Association of Sleep Duration with Stress Status and Nutritional Quotient for Korean Adolescents (NQ-A) in High School Students in Chungbuk

This study aimed to examine the association between sleep duration, stress levels, and dietary behavior in adolescents. A survey was conducted on 453 students (227 male, 226 female) in high schools in the Chungbuk area. The participants were divided into groups based on daily sleep duration: group I (＜5 hrs/d), group II (≥5 hrs/d and ＜6 hrs/d), group III (≥6 hrs/d and ＜7 hrs/d), and group IV (≥7 hrs/d). To measure the stress levels of participants, the survey had questions covering a variety of areas, including school life, family life, social relationships, and personal evaluation. To assess the dietary behaviors of participants, the survey included questions encompassing the Nutrition Quotient for Korean adolescents (NQ-A). Among female students, the sleep duration group IV had significantly lower total stress (P=0.022) and significantly lower stress in the personal evaluation area than the sleep duration group I (P=0.004). In the analysis of NQ-A, among female students, the sleep duration group IV showed significantly higher scores in balance (P=0.004), diversity (P=0.016), and total NQ-A score area (P=0.007) compared to other groups. There was a significant negative correlation between sleep duration and stress scores in total students (r=–0.24, P＜0.001), while a significant positive correlation was seen between sleep duration and NQ-A scores in female students (r=0.16, P＜0.05). To sum up, the longer the sleep duration, the lower the degree of stress, and the quality of meals which can be said to be a significant finding for high school students.

¹⁸FFET PET is a useful tool for treatment evaluation and prognosis prediction of anti-angiogenic drug in an orthotopic glioblastoma mouse model / 한국실험동물학회지

O-2-¹⁸F-fluoroethyl-l-tyrosine ([¹⁸F]FET) has been widely used for glioblastomas (GBM) in clinical practice, although evaluation of its applicability in non-clinical research is still lacking. The objective of this study was to examine the value of [¹⁸F]FET for treatment evaluation and prognosis prediction of anti-angiogenic drug in an orthotopic mouse model of GBM. Human U87MG cells were implanted into nude mice and then bevacizumab, a representative anti-angiogenic drug, was administered. We monitored the effect of anti-angiogenic agents using multiple imaging modalities, including bioluminescence imaging (BLI), magnetic resonance imaging (MRI), and positron emission tomography-computed tomography (PET/CT). Among these imaging methods analyzed, only [¹⁸F]FET uptake showed a statistically significant decrease in the treatment group compared to the control group (P=0.02 and P=0.03 at 5 and 20 mg/kg, respectively). This indicates that [¹⁸F]FET PET is a sensitive method to monitor the response of GBM bearing mice to anti-angiogenic drug. Moreover, [¹⁸F]FET uptake was confirmed to be a significant parameter for predicting the prognosis of anti-angiogenic drug (P=0.041 and P=0.007, on Days 7 and 12, respectively, on Pearson's correlation; P=0.048 and P=0.030, on Days 7 and 12, respectively, on Cox regression analysis). However, results of BLI or MRI were not significantly associated with survival time. In conclusion, this study suggests that [¹⁸F]FET PET imaging is a pertinent imaging modality for sensitive monitoring and accurate prediction of treatment response to anti-angiogenic agents in an orthotopic model of GBM.

Difference in food and nutrient intakes in Korean elderly people according to chewing difficulty: using data from the Korea National Health and Nutrition Examination Survey 2013 (6th)

BACKGROUND/OBJECTIVES: Chewing difficulty is a factor contributing to a poor nutritional status in the elderly. The aim of this study was to examine disparities in food and nutrition intakes among Korean elderly people with and without chewing difficulty. SUBJECTS/METHODS: This study utilized data from the sixth Korea National Health and Nutrition Examination Survey conducted in 2013. The study subjects included males and females over 65 years of age who were not required to adhere to a special diet due to disease or sickness. They were divided into groups according to their chewing ability. Those who found chewing “very difficult” or “difficult”, were combined to form the chewing difficulty group. Similarly, those who found chewing “moderately difficult”, “easy”, and “very easy” were combined to form the normal chewing group. RESULTS: Of the 999 subjects, 47.7% had chewing difficulties and the prevalence of chewing difficulty was higher in females than in males (P = 0.03) and higher in those 75 years of age and over than in younger individuals (P < 0.001). The chewing difficulty group had a significantly lower intake of fruits and vegetables (P < 0.05) and lower vitamin C and potassium intake than those in the normal group. Comparison of the percentages of Dietary Reference Intakes for Koreans (KDRIs) in the two groups indicated that the intake of most nutrients (energy, vitamin C, thiamin, riboflavin, niacin, calcium, phosphorus, sodium, potassium, and iron) were significantly lower in the chewing difficulty group than in the normal group. In particular, calcium intake was inadequate (51% of KDRIs) in the chewing difficulty group. CONCLUSIONS: The results indicate that chewing difficulty is closely related to food and nutrient intake in the elderly and can result in vitamin and mineral intake deficiencies. It is evident that the care of elderly subjects with chewing difficulty is essential for maintaining a healthy lifestyle.

Comparisons of Clinical Practicum Stress, Depression, and Self-Efficacy among Nursing Students: Focusing on Type D Personality and non-Type D Personality / 정신간호학회지

PURPOSE: The purpose of study was to examine and compare the clinical practicum stress, depression, and self-efficacy between Type D and non-Type D personality among nursing students. METHODS: This study used a descriptive correlational survey design. Subjects included a total of 120 nursing students (Type D personality: n=60, non-Type D personality: n=60) in Seoul, Korea. The collected data were analyzed using a descriptive statistics, χ² test, Fisher's exact test, independent t-test, ANCOVA, and Scheffe test as a post hoc test with SPSS/WIN 21.0 program. RESULTS: There were significant differences on clinical practicum stress (t=2.81, p=.029), depression (t=6.67, p<.001), and self-efficacy (t=9.84. p<.001) between non-Type D and Type D personality among nursing students. CONCLUSION: Type D personality in nursing students had higher clinical practicum stress and depression than them of non-Type D personality in nursing students. Nursing interventions or strategies for Type D personality in nursing students are needed to decrease clinical practicum stress and depression.

Current status of dietary education in elementary, middle and high school in Gyeonggi province: Comparison according to school level and placement of nutrition teacher / 한국영양학회지

PURPOSE: The purpose of this study was to investigate the current status of dietary education carried out by dieticians or nutrition teachers at elementary, middle, and high schools in Gyeonggi province. We compared dietary education status not only among school level but also between dieticians and nutrition teachers. METHODS: The survey using self-administered questionnaires was conducted by dieticians or nutrition teachers at 91 schools (43 elementary schools, 33 middle schools, and 15 high schools) in Gyeonggi province in December, 2015. The questionnaire consisted of questions regarding general characteristics of respondents, current status of dietary education, opinion about dietary education methods, and cooperation level of persons concerned. RESULTS: The placement rate of nutrition teachers was 50.5% overall. Only 36 out of 91 schools conducted regular dietary education, and the percentage of schools conducting regular dietary education was significantly different according to school level with the lowest percentage in high schools, equivalent to 20% (p = 0.003). The average annual dietary education time was 12.4 hours, and it was very low in high schools (5.1 hours) and in schools without a nutrition teacher (1.6 hours). The levels of cooperation and support from principals, teachers, parents, and students were significantly lower in high schools than elementary and middle schools (all p < 0.001) and in schools without a nutrition teacher than schools with a nutrition teacher (all p < 0.05). CONCLUSION: The results show that the level of dietary education is not enough and needs to be improved, especially at middle and high schools and at schools without a nutrition teacher. Government support polices need to be implemented to encourage dietary educational activities.

Fluoroscopy and Sonographic Guided Injection of Obliquus Capitis Inferior Muscle in an Intractable Occipital Neuralgia

Occipital neuralgia is a form of headache that involves the posterior occiput in the greater or lesser occipital nerve distribution. Pain can be severe and persistent with conservative treatment. We present a case of intractable occipital neuralgia that conventional therapeutic modalities failed to ameliorate. We speculate that, in this case, the cause of headache could be the greater occipital nerve entrapment by the obliquus capitis inferior muscle. After steroid and local anesthetic injection into obliquus capitis inferior muscles under fluoroscopic and sonographic guidance, the visual analogue scale was decreased from 9-10/10 to 1-2/10 for 2-3 weeks. The patient eventually got both greater occipital neurectomy and partial resection of obliquus capitis inferior muscles due to the short term effect of the injection. The successful steroid and local anesthetic injection for this occipital neuralgia shows that the refractory headache was caused by entrapment of greater occipital nerves by obliquus capitis inferior muscles.

Assessment of Accidents Occurrence and Cuisine Employees' Awareness of Workplace Safety in Contract Foodservice Management Company

The study was conducted in two phase. In phase I, workplace safety accidents were investigated that happened from 2004 to 2008 in 52 medium-sized contract managed foodservice companies located in Seoul. In phase II, a survey was conducted to examine the cuisine employees' awareness of workplace safety. The survey was administered to the same foodservice management companies from April 12 to April 20, 2009. The final response rate was 84% (N=336), and the data were analyzed using SPSS Windows (ver. 12.0). The analysis showed that more accidents occurred in the age groups of 51~60 and 41~50 and among women. Forty-four percents of the accidents were reported by the employees who had been engaged in foodservice for 1~4 years. The majority of the safety accidents occurred in May~June of the year and the injuries were related to the 'hands and arms'. Approximately 38.5% of the injuries happened during 'movement and transportation'. More than half of the accidents were not managed as 'industrial accidents'. By type of injuries, 28.6% of the accidents were 'fractures'. In terms of the companies' actions, 44% of the accidents were dealt by companies' paying medical bills. The results of this study could be useful to develop evaluation indicators for safety education programs, decrease cuisine employees' safety accidents, protect assets, and prevent various worker and industrial accidents to create a pleasant work environment.

Nucleoplasty in a patient with cervical disc extrusion with radiating pain of an upper extremity

Conventional open discectomy is considered as the standard treatment for cervical disc herniation.However, open discectomy does not always yield a successful result.Nucleoplasty is a newly developed minimal invasive spinal surgery that uses the Coblation technique.The concept of Coblation involves the use of radiofrequency energy to ablate the nucleus pulposus tissue in a controlled approach leading to reduction of pressure on the nerve roots.Inclusion criteria for candidates for nucleoplasty include complaints of symptoms related to a contained herniated disc or focal protrusion.We describe here our experience with the use of nucleoplasty for a 49-year-old male patient with a cervical disc extrusion.Percutaneous decompression with nucleoplasty using the Coblation technique for the treatment of cervical disc extrusion was successfully performed with an excellent result.

Scale Development for Measuring the Brand Images of Contract Foodservice Management Companies

The aim of this study was to measure the brand images of contract foodservice management companies by identifying brand image attributes and then developing a measurement scale to measure the weight of these attributes. The measurement scale was developed by following a 5-stage process that included face-to-face interviews with experts, literature review, questionnaire surveys, verification of scale validity, exploratory factor analysis, and confirmatory factor analysis. A total of 137 items measuring brand image were collected: 37 items from studies of brand image and corporate image, 55 items from studies of contract foodservice management companies and 45 items from the internet and websites of contract foodservice management companies. A survey was then conducted to assess the validity and reliability of the questionnaire items. Ultimately, the 137 items were reduced to 40 items. The calculated Cronbach's alpha for the 40 brand image items was 0.934, demonstrating good internal consistency. Based on exploratory factor analysis (EFA), employee attitude, menu content, corporate image, dining location and ambience, along with 33 subattributes, were identified as brand image attributes. Employee attitude was the most significant attribute influencing brand image. After confirmatory factor analysis (CFA) and a review process, four brand image attributes and 33 subattributes were finalized and incorporated into the scale.

A Study on Brand Personality Factors as Recognized by the Customers of Contract Foodservice Management Companies

The purpose of this study was to determine the attributes and factors of brand personality for contract foodservice management companies. Self-administered questionnaires were distributed to five students at universities operating under the top five companies in contract foodservice management. The following statistical analyses were conducted for the data assessment: descriptive analysis, t-test, ANOVA, reliability analysis, and factor analysis, using the SPSS Win(12.0) package program. From these analyses we divided a company's brand personality into the following five functional and emotional elements: sensibility, sincerity, confidence, competence, and excitement. Based on these five elements a total of 26 scales were developed to measure brand attributes of the companies. The variance was explained by 19.29% of sensibility, 17.65% of sincerity, 15.71% of confidence, 14.06% of competence, and 13.62% of excitement. The calculated Cronbach's alpha was more than .90 for all the scales measuring the five attributes, indicating good internal consistency. There were significant differences in sensibility(p<.01), sincerity(p<.001), creditability(p<.01), competence (p<.001), and excitement(p<.001) among the companies. In regards to overall brand personality, company a had a higher mean score for sincerity, while the other companies had higher mean scores for competence. Among the brand personalities, 'confidence' had the highest mean score with 3.36, followed by 'cooperation' (3.17), 'successful'(3.12), 'leadership'(3.11), and 'down-to-earth'(3.02).

Nutritional Labeling Practices for Processed Foods According to Food Category

The purpose of this study was to investigate the current nutritional labeling practices in the processed foods industry. Package labels provide consumers with reliable nutritional information, which has been considered a useful aid for food selection and a potent educational tool for nutrition in a daily life. To assess the nutritional composition labeling and nutritional claims on the food package labels in the Korean market, 2,691 processed foods were purchased from a wholesale market in August, 2004, under the food categories specified in the 2004 Food Code. Nutritional composition labels were found on 674 out of the 2,691 processed foods items. The study findings were as follows. Milk and dairy products showed the highest percentage(56.6%) of nutritional composition labeling among the food categories, while 86.2% of processed foods carried inappropriate types of nutrition labels. The title of nutritional composition labeling was ordered according to the nutritional composition presented on the top part of the box. The regulations method which it indicates was 77.8%. The expression unit of the nutritional composition labeling was per 100g(32.8%) or per OOg (29.4%). Of total processed foods, 83(3.1%) offered nutritional claims in their labels. These claims were divided into two ways: nutrient content claims and nutrient comparative claims. The most frequently used term in nutrient content claims was "contained"(67.2%). "More" or "Plus" were frequently used term in nutrient comparative claims(11.2%). Calcium was the most popular among nutrients claimed by processed foods(34.3%).

Improvement of Spinal Central Pain by Brachial Plexus Block: A case report / 대한통증학회지

Central pain is defined as pain associated with lesions of the central nervous system, and is among the most intractable of chronic pain syndromes. A 47 year-old-female, who had right arm and shoulder pain, was diagnosed with syringomyelia of the Arnold Chiari malformation type I and received foramen magnum decompression and a syringo-subarachnoid shunt. After the operation, the evoked pain was improved, but she complained of a continuous burning pain, coupled with cold and tactile allodynia. This symptom failed to fully subside on administration of oral medicine; therefore, brachial plexus block was performed, which relieved her pain transiently. Through repeated trials, a gradual decrease in the pain intensity and frequency was found. However, the way in which brachial plexus block improves spinal central pain is not completely known.
