The initial experiences of junior nursing college students when communicating with children during pediatric clinical practicum: A phenomenological study.

PURPOSE: Nursing students feel stressed during pediatric clinical practicum due to limited communication encounters with hospitalized children. The purpose of this study was to describe junior nursing college students' experiences of communicating with children during pediatric clinical practicums. DESIGN AND METHODS: A qualitative phenomenological research design was used. Purposive sampling was used to recruit 18 junior nursing college students who completed their pediatric clinical practicum. Data were collected using semi-structured interviews and were analyzed using Colaizzi's seven-step method for data analysis. RESULTS: Three themes emerged from the data. (1) Difficulties in communicating during initial practicum: fear, rejection, self-doubt of communication abilities, and unfamiliarity with the application of communication techniques posed frustrations among nursing students. (2) Efforts to learn during practicum: self-empowerment, seeking a diverse support system, adjusting communication methods, and striving to establish good relationships allowed nursing students to adapt to the pediatric curriculum. (3) Effective communication at the later stages of practicum: mastering fundamental communication techniques and exercising pediatric therapeutic communication techniques allowed nursing students to feel accomplished. CONCLUSIONS: Junior nursing college students initially encountered difficulties and frustration when communicating with children during their pediatric clinical practicum. This study serves as a guide for educators of pediatric nursing to design courses on communication with hospitalized children. PRACTICE IMPLICATIONS: These findings could be used to develop foundation courses on communicating with children for first-time pediatric nursing practicum students; for example, formulating a course on therapeutic play for children that encompasses communication techniques, pediatric ward simulation, and introduction to therapeutic play.

Psychosocial experiences in youth with Tourette syndrome: a systematic review and meta-synthesis.

Suffering from Tourette syndrome (TS) disrupts the daily lives and interpersonal relationships of patients. The psychosocial experiences of young people with TS are not yet clear. The aim of the systematic review is to identify and synthesize the psychosocial experiences of young people with TS. A meta-synthesis was conducted. PubMed, EMBASE, Cumulative Index to Nursing and Allied Health Literature, Web of Science, and Chinese Electronic Periodical Services databases were searched for articles published from their inception to February 2023. This review followed the Joanna Briggs Institute's Guidelines for Systematic Reviews according to a previously developed protocol. We used the confidence of synthesized qualitative findings (ConQual) approach to evaluate the credibility and dependability of the synthesized findings. This review included 12 qualitative studies from Western and Asian countries published between 2005 and 2019, representing 190 young people with TS. We identified five synthesized findings: affliction by intractable TS, TS was negatively perceived in the social and cultural context, self-adjustment in response to social interaction, response to receiving various interventions, and positivity in promoting self-acceptance. The ConQual grade for each generated synthesized finding ranged from low to moderate. The psychosocial experiences of youths living with TS are unique and are influenced by their interpersonal relationships, social context, and cultural framework. The findings recommend that healthcare providers assist young people in developing personalized symptom management strategies and provide guidance and care that meets the needs of each individual.

Factors associated with Tourette syndrome among adolescents in Taiwan: A cross-sectional correlational study.

PURPOSE: Adolescents with Tourette syndrome (TS) may suffer from learning difficulties (attention-deficit/hyperactivity disorder), challenges in interpersonal interactions (especially with peers), disruptions of daily routines (disruptive behavior disorders), and increased psychosocial stress, which can result in internalizing and externalizing behavioral problems, such as venting depression and stress through self-harm. The aim of this study was to investigate peer attachment in adolescents with TS and associated risk factors. DESIGN AND METHODS: Adolescents with TS aged 13-18 years were recruited from the outpatient departments of 2 hospitals in Taiwan. Participants completed a basic data sheet, the Beck Depression Inventory-II, the Chinese version of the State-Trait Anxiety Inventory, and the Chinese version of the Youth Self-Report. Descriptive statistics were performed. Structural equation modeling was used to verify the model proposed in this study and to analyze the overall fit and internal structure. RESULTS: A total of 452 adolescents with TS aged 10-19 years participated in this study, which aimed to investigate factors affecting peer attachment, depression, anxiety, and psychosocial maladaptation and to explore causal relationships between these factors. Peer attachment was significantly associated with grade point average (rs = -0.240, p < .001), birth order (rs = -0.118, p = .012), parental marital status (rs = -0.111, p = .018), parenting style (rs = -0.138, p = .003), family monthly income (rs = 0.124, p = .008), and weekly hours on the internet (r = -0.164, p < .001). CONCLUSIONS: These results suggest that depression, anxiety, and peer attachment affect psychosocial development. PRACTICAL IMPLICATIONS: The findings may help clinical staff manage adolescents' severe emotional distress and psychosocial maladaptation.

Associations among quality of life, activities, and participation in elderly residents with joint contractures in long-term care facilities: a cross-sectional study.

BACKGROUND: Joint contractures and degenerative osteoarthritis are the most common joint diseases in the elderly population, can lead to limited mobility in elderly individuals, can exacerbate symptoms such as pain, stiffness, and disability, and can interfere with social participation and quality of life, thus affecting mental health. However, relevant studies on this topic are very limited. This study describes the associations of joint contracture categories and sites in elderly residents in long-term care facilities with their quality of life, activities, and participation. METHODS: Elderly individuals with joint contractures who were residents in long-term care facilities were recruited. The World Health Organization (WHO) Quality of Life and the WHO Disability Assessment Schedule 2.0 were used to survey the participants. Correlations, multiple linear regressions, and multiple analyses of variance, with joint contractures as the response variable, were used in the statistical analysis. RESULTS: The final statistical analysis included 232 participants. The explanatory power of contracture sites on activities and participation had a moderate strength of association (η2 = .113). Compared with elderly residents with joint contractures and osteoarthritis isolated to the upper limbs, those with joint contractures and osteoarthritis in both the upper and lower limbs had significantly worse activity and participation limitations. No significant differences in activity and participation were found between elderly residents with joint contractures affecting only the upper limbs and those with joint contractures affecting only the lower limbs (F1,226 = 2.604 and F1,226 = 0.674, nonsignificant). Osteoarthritis had the greatest impact on activity limitations and participation restrictions among elderly residents with joint contractures affecting both the upper and lower limbs (F1,226 = 6.251, p = .014). CONCLUSIONS: Elderly residents in long-term care facilities belonging to minority groups, with a history of stroke, and with osteoarthritis are at a high risk of developing activity limitations and participation restrictions. Moreover, compared with other contraction sites, regardless of osteoarthritis, joint contractures affecting both the upper and lower limbs were associated with the greatest activity limitations and participation restrictions. TRIAL REGISTRATION: This study has been registered in the Chinese Clinical Trial Registry, registration number and date: ChiCTR2000039889 (13/11/2020).

Psychometric validation of the Chinese version of the PaArticular Scales among elderly residents in long-term care facilities with joint contractures.

BACKGROUND: Joint contractures, which affect activity, participation, and quality of life, are common complications of neurological conditions among elderly residents in long-term care facilities. This study examined the reliability and validity of the Chinese version of the PaArticular Scales in a population with joint contractures. METHODS: A cross-sectional study design was used. The sample included elderly residents older than 64 years with joint contractures in an important joint who had lived at one of 12 long-term care facilities in Taiwan for more than 6 months (N = 243). The Chinese version of the PaArticular Scales for joint contractures was generated from the English version through five stages: translation, review, back-translation, review by a panel of specialists, and a pretest. Test-retest reliability, internal consistency reliability, construct validity, and criterion validity were evaluated, and the results were compared with those for the World Health Organization Quality of Life scale and the World Health Organization Disability Assessment Schedule. RESULTS: The Chinese version of the PaArticular Scales had excellent reliability, with a Cronbach α coefficient of 0.975 (mean score, 28.98; standard deviation, 17.34). An exploratory factor analysis showed three factors and one factor with an eigenvalue > 1 that explained 75.176 and 62.83 % of the total variance in the Activity subscale and Participation subscale, respectively. The subscale-to-total scale correlation analysis showed Pearson correlation coefficients of 0.881 for the Activity subscale and 0.843 for the Participation subscale. Pearson's product-moment correlation revealed that the correlation coefficient (r) between the Chinese version of the PaArticular Scales and the World Health Organization Disability Assessment Schedule was 0.770, whereas that for the World Health Organization Quality of Life scale was - 0.553; these values were interpreted as large coefficients. CONCLUSIONS: The underlying theoretical model of the Chinese version of the PaArticular Scales functions well in Taiwan and has acceptable levels of reliability and validity. However, the Chinese version must be further tested for applicability and generalizability in future studies, preferably with a larger sample and in different clinical domains.

Development and Validation of the Social Adjustment Scale for Adolescents with Tourette Syndrome in Taiwan.

PURPOSE: The aim of this study developed the psychometric properties of the social adjustment scale for adolescents with Tourette syndrome (SASATS). DESIGN AND METHODS: A cross-sectional study design was conducted. 346 adolescents with Tourette syndrome (TS) were purposively sampled from pediatric outpatient departments at two hospitals in Taiwan. The scale was developed through a phenomenological study of adolescents with TS and by reviewing the literature. The reliability analysis of the SASATS was performed using the corrected item-total correlations coefficients, Cronbach alpha coefficients, and test-retest correlations. An exploratory factor analysis and confirmatory factor analysis were used to examine the construct validity. RESULTS: The content validity index of 0.89 was obtained, and acceptable model fit was achieved according to the explanatory factor analysis and confirmatory factor analysis. The final scale had 17- items and four factors: relationship between self and TS, academic performance, family relationship, and peer interaction. Acceptable values of 0.81 and 0.87 were obtained for the test-retest and internal consistency reliabilities, respectively. CONCLUSIONS: The SASATS is a reliable and valid instrument for evaluating social adjustment status in TS adolescents. PRACTICE IMPLICATIONS: The SASATS is easy to use and offers an effective scale for nurses and healthcare providers in clinical and academic settings. It can quickly measure and detect the psychological functioning of the social adjustment of adolescents with TS during interpersonal interactions. Moreover, interventions can be provided to improve adolescents' social adjustment and promote their mental health.

Effects of preferred music therapy on peer attachment, depression, and salivary cortisol among early adolescents in Taiwan.

AIMS: To explore the effects of preferred music therapy on peer attachment, depression, and salivary cortisol among early adolescents. BACKGROUND: As adolescents enter puberty, they start to seek partnering relationships among peers. Peer attachment is central for adolescents and greatly influences their physical and psychological development. DESIGN: A pre-test-posttest control group design. METHODS: The data were collected from July - October 2016. A total of 65 individuals were included. The treatment group received 40 min of music therapy twice per week over the course of 10 weeks. The control group maintained its typical routine. The research data were collected using structured questionnaires, including basic information, the Inventory of Peer Attachment, the Beck Depression Inventory-II questionnaires, and salivary cortisol concentrations. Statistical analysis methods included percentages, chi-square tests, t tests, analyses of covariance, and the Johnson-Neyman technique. RESULTS: There were statistically significant differences in peer attachment, depression, and salivary cortisol levels in the music group compared to the control group (p < 0.05). Additionally, the findings showed that early adolescents with more severe depression experienced greater improvement through preferred music therapy. CONCLUSION: The results allude to the beneficial effects of receiving preferred music therapy in terms of the peer attachment, depression, and salivary cortisol levels of early adolescents. Adjustments should be made based on the characteristics of student groups to develop suitable and safe music therapy and to reduce the risks of poor mental health.

Social adjustment experiences of adolescents with Tourette syndrome.

AIMS AND OBJECTIVES: To explore and describe the experience of social adjustment of adolescents with Tourette syndrome in Taiwan. BACKGROUND: Although Tourette syndrome is a non-life-threatening disease, the inherent difficulties in controlling tics and comorbidities can cause long-term physical and psychological issues, as well as social maladjustment among adolescents. Good social adjustment can promote mental health among adolescents. Currently, it is not clear how adolescents with Tourette syndrome can self-adjust and maintain harmonious social interaction with others. DESIGN: Descriptive phenomenological approach was used in this study. Four criteria were applied to establish the trustworthiness or methodological rigour. METHODS: Sixteen adolescents with Tourette syndrome were recruited by purposive sampling from a medical centre in Northern Taiwan. Semistructured one-on-one interviews were performed from March 2014-April 2015 for data collection. Every participant was interviewed once or twice, and each interview lasted for duration of around 60-90 min. Data were analysed with Giorgi's phenomenological method for data analysis. RESULTS: Three themes were identified from the adolescent' interviews. The themes were included visible and invisible destitution, moulding a socially acceptable self and coexisting friends and foes. CONCLUSIONS: Adolescents with Tourette syndrome experienced that tics are often not understood nor accepted during social interactions with others. However, with age and autonomy of adolescents, they were able to adjust and develop a socially acceptable body image and maintain amicable social interactions with others. Accompanied by positive thinking, support from friends and families, the adolescents could achieve good social adjustments for living with Tourette syndrome. RELEVANCE TO CLINICAL PRACTICE: The experiences and feelings highlighted in this study can bring awareness to nurses and healthcare professionals for developing interventions that promote healthy social adjustment and mental health for adolescents with Tourette syndrome.

An Investigation of the Factors Related to Low Parent-Adolescent Attachment Security in Taiwan.

BACKGROUND: Adolescence may involve increases in many behavioral problems and psychosocial maladaptation. Adolescents must successfully cope with these challenges to achieve positive developmental milestones. OBJECTIVES: To investigate whether low parental attachment security among adolescents in Taiwan is associated with their demographic characteristics, psychosocial maladaptation, and depression. DESIGN: A cross-sectional survey. A total of 335 adolescents completed the questionnaires. The Inventory of Parent and Peer Attachment, the Chinese version of the Youth Self-Report, and the Beck Depression Inventory-II were used to survey the participants. Correlation and multiple linear regressions, using low attachment security as the response variable, were used in the statistical analysis. RESULTS: The prevalence of Taiwanese adolescents with low parental attachment security was 38.5%. Low parental attachment security in adolescents was significantly associated with parental remarriage status and psychosocial maladaptation. CONCLUSIONS: By considering these risk factors, nursing educators and nurses could develop effective interventions to strengthen parent-adolescent attachment security.

The effects of Chinese five-element music therapy on nursing students with depressed mood.

This study aimed to evaluate the effects of Chinese five-element music therapy on nursing students with depressed mood. We randomly assigned 71 nursing students from Taiwan with depressed mood to the music and control groups. The music group (n = 31) received Chinese five-element music therapy, whereas the participants in the control group (n = 40) maintained their routine lifestyles with no music therapy. All of the participants were assessed using the Depression Mood Self-Report Inventory for Adolescence, and their salivary cortisol levels were measured. The study found that there was a significant reduction in depression between the pre- and posttherapy test scores and in salivary cortisol levels over time in the music group. After receiving the music therapy, the nursing students' depression levels were significantly reduced (P = 0.038) compared with the control group (P < 0.001). These results indicate that the Chinese five-element music therapy has the potential to reduce the level of depression in nursing students with depressed mood.

The development and psychometric evaluation of the Chinese version of the Maternal Attachment Inventory.

AIMS AND OBJECTIVES: To develop the Maternal Attachment Inventory (MAI) into Chinese and assess its psychometric properties. BACKGROUND: The MAI measures of maternal affectionate attachment. This scale displays the most appropriate indicators associated with attachment and has been widely adopted in different fields for measuring maternal-infant attachment. DESIGN: Cross-sectional survey design. METHODS: The study was carried out in two clinics. From the accessible population of 507 samples, a simple random sampling method of selection was used to randomly choose 200 names of mothers at 4-8 months after delivery using a computer. One hundred and eighty-one mothers agreed to participate in the study. The Chinese version of the MAI (CMAI) was developed in five stages: translation, review, back-translation, a review by a panel of specialists and a pilot test. Regarding the reliability of the CMAI, a test of correlations between the subscales and the entire scale was performed consecutively. With respect to the validity of the MAI, exploratory factor analyses, a test of relationships between items and subscales, and an analysis of concurrent criterion-related validity were conducted. RESULTS: The CMAI contains four factors in its structure. The CMAI and its subscales possess good internal consistency; the Cronbach's α coefficient was 0·94. In addition, the Pearson product-moment correlation coefficient between the CMAI and the Maternal-Fetal Attachment Inventory (MFAI) and between the CMAI and the Maternal-Infant Attachment Inventory (MIAI) was 0·38 and 0·5, respectively. This suggests significant medium and high respective correlations between the CMAI and these two scales. One major limitation of this study is that participants were recruited from two clinics located in central Taiwan. CONCLUSIONS: The CMAI possesses acceptable reliability and validity for use in measuring the levels of attachment and affectional ties between mothers and their infants. RELEVANCE TO CLINICAL PRACTICE: The CMAI provides further evidence of the applicability of the CMAI in clinical maternity care services.

Effects of a Moodle-based E-learning environment on E-collaborative learning, perceived satisfaction, and study achievement among nursing students: A cross-sectional study.

BACKGROUND: Studies suggest that e-learning environments (ELEMs) in nursing education may be more effective than traditional face-to-face teaching, as they lead to learning outcomes that equal or exceed those of face-to-face teaching. OBJECTIVES: To determine whether using ELEM for educational applications can significantly improve e-collaborative learning, perceived satisfaction, and study achievement among nursing students in a paediatric nursing course. DESIGN: Nonrandomized pretest-posttest quasi-experimental research design. SETTINGS: A medical college in northern Taiwan. PARTICIPANTS: Eighty-four students (52 in the non-ELEM group and 32 in the ELEM group) completed both the pretest and posttest. METHODS: Third-year nursing students were recruited and nonrandomly assigned to an experimental group (ELEM) and a nonexperimental group (non-ELEM) of their choice. Students in the former group received traditional classroom teaching without the use of Moodle-based ELEMs, while those in the latter completed the course through Moodle-based ELEMs and classroom lectures. RESULTS: Regarding perceived satisfaction, e-collaborative learning, and study achievement, the overall test results indicated a significant difference in the posttest between the two groups (F (1,82) = 10.622, P = 0.002), (F (1,82) = 9.481, P = 0.003), (F (1,82) = 59.301, P < 0.001, respectively). The explanatory power η2 reached 11.5 %, 10.4 %, and 42.0 %, respectively. CONCLUSION: The students who used Moodle-based ELEMs combined with classroom teaching showed significantly higher levels of e-collaborative learning, perceived satisfaction, and study achievement in the paediatric nursing course. ELEMs for educational purposes can serve as effective complementary learning tools for paediatric nursing courses.

Effects of video-recorded role-play and guided reflection on nursing student empathy, caring behavior and competence: A two-group pretest-posttest study.

AIM: The study examined the differences in nursing student empathy, caring behavior and competence between the experimental and control groups before and after educational intervention and to predict the factors affecting their core competencies. BACKGROUND: Educating nursing students in empathy and caring behaviors before entering clinical practice is challenging. DESIGN: We used a two-group pretest and post-test quasi-experimental design. METHODS: First-year nursing students from medical schools in Taiwan participated in our study. Data were collected between March and May 2022. The learning method used with the intervention group was role-playing with videos and guided reflection. The control group was exposed to traditional curriculum. Empathy, caring behavior and competence were measured using the Jefferson Scale of Empathy- Healthcare Providers, the Caring Behaviors Scale and the Nursing Student Competence Scale. RESULT: A total of 72 participants (40 in the experimental group and 32 in the control group) were included in the final statistical analysis. The response rate was 92%. Statistically significant differences in nursing student empathy, caring behavior and competence were observed between the experimental and control groups (p < .05). The η2 effect levels were 0.083, 0.223 and 0.270. Higher caring behavior scores were significantly associated with higher nursing student competence scores (ß = 0.81, 95% CI:0.66-0.97). CONCLUSIONS: Education based on video role-play and guided reflection improved empathy, caring behavior and nursing competence in first-year nursing students.

Development and validation of a brief version of the traditional Chinese Stressors in Nursing Students scale among college nursing students in Taiwan.

Objective: The 43-item Stressors in Nursing Students (SINS) scale has been evaluated among nursing students in several countries, including China, Hong Kong, Japan, Pakistan, and Spain. However, the original four-factor structure has not been consistently replicated in all of these populations. The aim of this study was to develop a brief version of the traditional Chinese SINS (TC-SINS) scale and to validate it in Taiwanese nursing students. Materials and Methods: Data obtained from a cross-sectional survey study of 814 nursing students in a nursing college and a university in Taiwan were randomly divided into two parts. The first part was used to conduct an exploratory factor analysis using principal axis factoring with oblique rotation. After the removal of cross-loading items, the resulting scale was validated with the data from the second part using confirmatory factor analysis. Results: A three-factor solution (social, clinical, and education) with 23 items accounting for 54.5% of variance was obtained in the exploratory factor analysis. The confirmatory factor analysis further reduced the number of items to 20. The goodness-of-fit indexes were good (Root Mean Square Error of Approximation = 0.075 and Comparative Fit Index = 0.90). Conclusions: The number of items in the TC-SINS could be reduced from 43 to 20, without sacrificing its psychometric properties. The brief version of TC-SINS might be able to reduce respondent burden.

Optical magnetic response in three-dimensional metamaterial of upright plasmonic meta-molecules.

We report the first three-dimensional photonic metamaterial, an array of erected U-shape plasmonic gold meta-molecules, that exhibits a profound response to the magnetic field of light incident normal to the array. The metamaterial was fabricated using a double exposure e-beam lithographic process. It was investigated by optical measurements and finite-element simulations, and showed that the magnetic field solely depends on the plasmonic resonance mode showing either enhanced in the centre of the erected U-shape meta-molecule (16 times enhancement) or enhanced around two prongs of erected U-shape meta-molecule (4 times enhancement).

Perinatal attachment in naturally pregnant and infertility-treated pregnant women in Taiwan.

AIM: This article is a report of a study of the differences in maternal-foetal attachment and maternal-infant attachment among naturally pregnant and infertility-treated pregnant women in Taiwan. BACKGROUND: Studies have shown that infertility treatment is likely to make up an increasing proportion in the coming years. As these experiences are unique, the attachment relationship may be affected. METHOD: The research data were collected from two obstetrics clinics which were located in central Taiwan. In 2008, all participants (n = 125) were asked to fill out the prenatal questionnaires at the beginning of the study and were followed up with postnatal questionnaires that were mailed to them 1-2 months after labour (n = 110). We used chi-square tests for categorical and t- tests for continuous variables. Multivariate analysis of variances was then performed, and changes in the maternal-foetal attachment and maternal-infant attachment Scales were assessed. FINDINGS: Women who became pregnant after fertility treatment had higher maternal-foetus and maternal-infant attachment scores, and this result was statistically significant; pregnancy mode and level of education are the main factors that have a significant effect on maternal-foetus attachment; and pregnancy mode and participation in prenatal education have a main effect on maternal-infant attachment. CONCLUSION: Development of a specific support group for mothers, such as a group for prenatal education, and providing useful resources for pregnant women with a lower level of education are involved in the future research studies for therapeutic intervention.

[Introduction to nursing aesthetics].

Empirical, aesthetic, ethical, and personal knowing are the four fundamental patterns of knowledge inquiry. Of these, the aesthetic knowing pattern is least discussed in nursing literature. This article discusses the definition of nursing aesthetics; its utilization in practice; and correlations between aesthetics and clinical practice. One of the advantages inherent to nursing is its ability to deliver skillful care directly to patients. Skillful performance is essential to reduce discrepancies between goals and patterns. Aesthetic nursing addresses more than the form of nursing. It further addresses the crucial elements of nursing knowledge. The science of nursing is influential in its ability to attain harmony among abundant empiric content, power of beneficence, and pleasure of aesthetic experience. In clinical practice, nurses can employ aesthetic nursing through various channels to create meaning and promote the professional image of nurses. Concepts listed in this article may be utilized in clinical supervision, practice and education.

Effects of three-dimensional holograms on the academic performance of nursing students in a health assessment and practice course: A pretest-intervention-posttest study.

BACKGROUND: Traditional teaching approaches are generally teacher-directed, and students are taught in a manner that is conducive to sitting and listening. Using three-dimensional (3D) holograms has many benefits in a higher education environment. However, relevant studies on this topic are very limited. OBJECTIVES: To confirm the efficacy of 3D holograms for educational purposes to support the academic and practical performance of nursing students. DESIGN: A randomly allocated pretest and posttest quasi-experimental design. SETTINGS: Mackay Medical College in Taiwan. PARTICIPANTS: Ninety third-year nursing students at a medical school in Taiwan. METHODS: The data were collected between January and May 2020. The participants were randomly allocated to an intervention group and a control group. The learning method used in the intervention group was a combination of a 3D hologram learning module and classroom lectures. The control group was exposed to classroom lectures without 3D holograms. The tool included hardware (Windows Mixed Reality Helmet and VR Remote Control) and software (Health Assessment® and Patient First Patient Condition VR System®). The Health Assessment and Practice Knowledge Assessment tool and the Health Assessment and Practice Techniques Performance tool were used to evaluate the effects of the study intervention on the knowledge and techniques of the students. RESULTS: A total of 79 participants (40 in the intervention group and 39 in the control group) were included in the final statistical analysis. The response rate was 88%. Statistically significant differences in knowledge and practical learning in the health assessment and practice course were observed between the intervention group and the control group (p < .05). The η2 effect level was 0.134. CONCLUSIONS: After attending classroom lectures, the students who also attended the 3D hologram-based laboratory courses had significantly higher knowledge and practical learning scores. This approach may be used as a complementary learning tool in higher education.

Electromagnetic energy vortex associated with sub-wavelength plasmonic Taiji marks.

The Taiji symbol is a very old schematic representation of two opposing but complementary patterns in oriental civilization. Using electron beam lithography, we fabricated an array of 70 × 70 gold Taiji marks with 30 nm thickness and a total area of 50 × 50 µm(2) on a fused silica substrate. The diameter of each Taiji mark is 500 nm, while the period of the array is 700 nm. Here we present experimental as well as numerical simulation results pertaining to plasmonic resonances of several Taiji nano-structures under normal illumination. We have identified a Taiji structure with a particularly interesting vortex-like Poynting vector profile, which could be attributed to the special shape and dimensions of the Taiji symbol.
