ABSTRACT
Purpose@#This study sought to predict the reasons for skipping breakfast by adolescents aged 13–18 years using the 7th Korea National Health and Nutrition Examination Survey (KNHANES). @*Methods@#The participants included 1,024 adolescents. The data were analyzed using a complex-sample t-test, the Rao Scott χ2-test, and the classification and regression tree (CART) algorithm for decision tree analysis with SPSS v. 27.0. The participants were divided into two groups, one regularly eating breakfast and the other skipping it. @*Results@#A total of 579 and 445 study participants were found to be breakfast consumers and breakfast skippers respectively. Breakfast consumers were significantly younger than those who skipped breakfast. In addition, breakfast consumers had a significantly higher frequency of eating dinner, had been taught about nutrition, and had a lower frequency of eating out. The breakfast skippers did so to lose weight. Children who skipped breakfast consumed less energy, carbohydrates, proteins, fats, fiber, cholesterol, vitamin C, vitamin A, calcium, vitamin B1, vitamin B2, phosphorus, sodium, iron, potassium, and niacin than those who consumed breakfast. The best predictor of skipping breakfast was identifying adolescents who sought to control their weight by not eating meals. Other participants who had low and middle-low household incomes, ate dinner 3–4 times a week, were more than 14.5 years old, and ate out once a day showed a higher frequency of skipping breakfast. @*Conclusion@#Based on these results, nutrition education targeted at losing weight correctly and emphasizing the importance of breakfast, especially for adolescents, is required. Moreover, nutrition educators should consider designing and implementing specific action plans to encourage adolescents to improve their breakfast-eating practices by also eating dinner regularly and reducing eating out.
ABSTRACT
Purpose@#The purpose of the study was to analyze the priorities for educational content regarding precautions to be taken to prevent safety accidents for employees in school foodservice using the Borich priority formula and the Locus for Focus model. @*Methods@#A survey was conducted in February 2019 on 194 employees in elementary school and 122 employees in middle- and high school foodservice in the Jeonbuk area. Demographic characteristics, status of safety accidents, safety education, and their importance and performance levels were assessed using a self-administered questionnaire. The priorities for the educational content on precautions to prevent safety accidents were based on a 3-step analysis method, including the paired sample t-test, Borich priority formula, and the Locus for Focus Model. @*Results@#The average perceived importance of the precautions to be taken against safety accidents of employees in elementary-, middle-, and high schools was higher compared to the average performance of the employees (p < 0.001). The top priority for elementary school employees was caution against falls during the cleaning of the gas hood and the trench in the kitchen. In addition, ‘awareness of chemical signs’ was added as one of the top priorities of middle- and high school employees. The second highest priority items were ‘do stretching’, ‘safely adjusting workbench height’, ‘keeping the right attitude’, ‘using assistive devices when moving heavy things’, and ‘checking the material safety data sheet’, which were the same for all elementary, middle- and high school employees. @*Conclusion@#Thus, to improve the educational preparedness of employees in the area of safety precautions, eight safety/accident prevention items should be included in the safety education program.
ABSTRACT
Purpose@#The purpose of the study was to analyze the status of dietary behavior and nutrition intakes according to the gender and the level of physical activity of adolescents. @*Methods@#Data from 659 adolescents aged 13 to 18 years who participated in the Korea National Health and Nutrition Examination Survey (2017–2018) were analyzed. Collected data were analyzed using complex sampling data analysis with SPSS v. 27.0. @*Results@#The adolescents were categorized into three groups based on their physical activity as follows: The first group with high physical activity (8.9%), a second group with normal physical activity (29.7%), and a third group without physical activity (61.4%). Boys showed significantly higher physical activity than the girls. Adolescents with high physical activity had a significantly lower body mass index than adolescents without physical activity, but their meal regularity, subjective health status, and recognition of body image were significantly higher. In terms of biochemical factors, adolescents with high physical activity had lower triglycerides and cholesterol than adolescents without physical activity, while hemoglobin and hematocrit were significantly higher. In addition, the intakes of energy, carbohydrates, proteins, fat, vitamin B 1 , niacin, calcium, phosphorus, sodium, potassium, iron increased significantly as adolescents’ physical activity increased. @*Conclusion@#The physical activity of adolescents had a positive effect on dietary behavior, lifestyle, and nutritional factors. Therefore, it is necessary to increase participation in physical classes in schools and develop various programs considering the level of physical activity among adolescents.
ABSTRACT
Purpose@#The purpose of the study was to investigate whether adherence to the Korea Healthy Eating Index (KHEI) was associated with metabolic syndrome and risk markers. @*Methods@#The participants included 8,345 adults, aged 20–59 years, who took part in the 7th Korea National Health and Nutrition Examination Survey (KNHANES). The data were analyzed using a complex-sample t-test, the Rao Scott χ 2 -test, and logistic regression analysis on the SPSS v. 26.0 software. The participants were divided into four groups by quartiles of KHEI scores. @*Results@#The average KHEI score was 61.06 points out of 100, and the women’s score (62.50points) was significantly higher than that of men (59.63 points). The KHEI quartiles status showed significant differences by age (p < 0.001), household income (p < 0.001), smoking status (p < 0.001), and food security. Specifically, the KHEI quartiles in the men showed significant differences in education (p < 0.001) and economic activity (p < 0.001) whereas those of women showed significant differences in alcohol-consumption (p < 0.001), depression (p < 0.01) and eating-out (p < 0.001). As the KHEI scores increased, the proportion of subjects with an energy intake below the estimated energy requirement (EER) was lower, and significantly better levels of intake were observed for carbohydrate, protein, vitamin C, calcium, vitamin B 1 , vitamin B 2 , and niacin. The incidence of the metabolic syndrome risk factors, hypertriglyceridemia and hyperglycemia for men and hypertension, and hyperglycemia for women showed significant differences. The KHEI scores were inversely associated with abdominal obesity, hypertriglyceridemia, low high-density lipoprotein cholesterol, hyperglycemia, hypertension, and metabolic syndrome. @*Conclusion@#Based on these results, we conclude that higher adherence to the KHEI was associated with lower metabolic syndrome risk factors and incidence of the metabolic syndrome.
ABSTRACT
Penetrating neck injuries constitute 5-10% of all trauma cases. These injuries may cause life-threatening suppurative or vascular complications, but the severity and extent of damage depends upon the inflicting object and the involved structures. If significant complications are not expected, then it is best to leave the foreign body embedded and avoid surgical risks. We present a rare case of a foreign body embedded in the neck causing tinnitus and foreign body sensation.

Trichofolliculoma is an uncommon follicular hamartoma of hair follicle tissue, typically occurring on the face and skin of the head and neck and appearing as papules or nodules. Dents in the central portion and immature white hair may be observed. Asymptomatically, trichofolliculoma occurs at any age but rather frequently in adults in many cases. A 47-year-old man presented a right ear canal mass, which had not been treated for 12 years. The tumor began to increase its size 4 years ago. A little red bump blocked the entrance of the right external auditory canal and there was a little dinge at the center of bump with growing black hair. This case was first reported in our country. Thus, we report this rare case with a review of the literature.

BACKGROUND AND OBJECTIVES: Tinnitus can be classified into two types, otogenic and somatic tinnitus. Somatic tinnitus can occur even when the ear is normal, as it is known that tinnitus can occur after there is movement in the muscles of the head and neck. This study aims to characterize tinnitus and clarify the nature of tinnitus when it occurs from the contraction of the head and neck muscle. SUBJECTS AND METHOD: Thirty-five people with normal hearing, who had no history of otitis media or inner ear disease, were taken as subjects. First, we investigated whether the natural tinnitus occurred or not in the silent environment and checked its characteristics for five minutes. We then implemented eight different kinds of muscle contractions maneuver and measured whether the tinnitus occurred and the recorded the onset time, duration and location of the occurrence of the tinnitus. RESULTS: Among the total of 35 subjects inspected, 15 (42.9%) people felt the natural tinnitus. In terms of natural tinnitus, ringing was the most common characteristic and heard most often from both sides. Twenty (57.1%) subjects out of total 35 subjects inspected felt tinnitus after the contraction of the head and neck muscles. Tinnitus after the resistance to a force applied by the people to the occiput was the most common for 14 (40.0%) people, followed by parietal and right temporal area. The most common location was the left side for 6 (17.1%) subjects followed by right side and both sides. For the type of tinnitus after the contraction of muscles, ringing was observed the most by 6 (17.1%) subjects, followed by high frequency and pulsatile sound. The average onset time of the tinnitus was 8.8 seconds and the average duration was 29.6 seconds. CONCLUSION: The study showed that the muscle contraction of head and neck affects the occurrence of tinnitus for people who had no tinnitus. By clarifying the occurrence of tinnitus due to the contraction of muscles, the study identified the basic features of hearing and the role of the somatic tinnitus.

Phenolate type siderophore was produced in Pseudomonas sp. PY002 (P. sp. PY002) which cultured in M9 minimal medium supplemented with 0 to 500 uM of dipyridyl. Pyochelin, a kind of siderophore, was detected as a single broad absorption band (280 nm) at pH 12.0, which is a characteristic of phenolate type siderophore. The 280 nm absorption spectrum of pyochelin was changed to 310 nm at pH 1.5. The pyochelin produced was a structurally unique phenolate siderophore, designated 2-[2-(o-hydroxyphenyl)-2-thiazolin-4-yl]-3-methyl-4-thiazolidine car- boxylic acid on the analysis of infrared radiation and 'H and ""C nuclear magnetic resonance spectroscopy. Additionally, purified pyochelin increased the cell growth rate, like as growth fac- tor. All these results suggest that phenolate type siderophore play an important role in cell growth of P. sp. PY002.
