Objectives: This study was designed to find out factors that are needed to be improved for the Buddhist training environment of Sramanera Sramanerika monks, who have been newly adapted for their life style after becoming a monk, and to provide basic data for the development of the standard diet in Buddhist temples. Methods: A self-administered questionnaire was applied to 365 Sramanera Sramanerika monks at 11 Buddhist monk universities. The questionnaire was designed to investigate their dietary habits, dietary evaluation, satisfaction of food service, and food preferences. Results: The study population consisted of 52.6% men, and 47.4% women. The subjects who had a vegetarian diet before joining the Buddhist priesthood were 27.7% women, and 13.5% men (p<0.01). 42.2% of the total subjects felt that they are healthy now and 19.4% felt weak. The most difficulty of dieting adaptation as soon as entering the priesthood was the strict diet rules (42.9%). The subjects considered health or nutrition (40.0%) highly when having meals. 94.8% women, 84.1% men ate breakfast every day (p<0.001). Women (55.4%) frequently ate snacks more than men (26.6%) (p<0.001). The results of the dietary evaluation indicated that the intake of milk, soy milk or dairy products and beans or tofu received lower than 3 points and women had lower point result than men (p<0.001). Foods with higher preference were grilled mushrooms, grilled laver, miso stew, sweet and sour mushrooms, steamed tofu with seasoning. Conclusions: Women were more interested in their health than men but they also required to improve the nutritional eating habits. It appeared that the lower intake rates of the calcium containing food (milk and dairy), and proteins (beans and tofu) could result in nutritional imbalance. Therefore, it is necessary to offer food based on the standard menu plan with consideration given to their food preferences in order to maintain their health and desirable dietary habits.

The COVID-19 pandemic has led to the curtailing of school meal services. This study aimed to compare the diets of students attending online classes who prepared their own lunch under these circumstances, with those of their counterparts who had their lunch prepared for them. In December 2020, a survey was conducted on 204 students (75 male and 129 female) at a high school in Gyeonggi-do. The results showed that more girls prepared their own lunch than boys (53.5% vs. 36.0%, respectively, P<0.05). Further, more participants with working mothers prepared their own lunch compared to those with unemployed mothers (60.8% vs. 23.0%, respectively, P<0.001). Lunch was prepared either by parents (47.5%), themselves (47.1%), or others (5.4%). A comparison of the Nutrition Quotient (NQ) was carried out between the subjects who prepared their own lunch and those who ate lunch prepared by their parents. The students who prepared their own lunch had significantly lower total (P<0.05), balance (P<0.01), and environment (P<0.01) sectors of NQ-A than their counterparts. Especially, subjects whose parents prepared their lunch had bean·tofu·soy milk more frequently (P<0.01), tended to eat vegetables more frequently (P=0.059), and skipped breakfast less frequently (P<0.01). In conclusion, this study suggested that high school students who have to prepare their own lunch at home during the COVID-19 pandemic are the newly emerging nutritionally vulnerable group. This study may provide the basic information necessary for preparing measures to maintain the diet quality of high school students during the COVID-19 pandemic and similar situations in the future when school meal services may not be available.

BACKGROUND/OBJECTIVES: This study measured the effects of a taste education program developed in Korea on food neophobia and willingness to try novel foods in school children. SUBJECTS/METHODS: One-hundred and twenty school children (aged 7-9 years) residing in Seoul participated in 12 sessions of a taste education program for 3 months. The Korean taste education program was adapted from "Les classes du gout" by J. Puisais and modified to suit a Korean education environment. The study subjected school children to pre- and post-programs on food neophobia and willingness to try novel foods (WTNF), in addition to children's food neophobia in their parents. A total of 101 survey data were analyzed using SPSS 18.0. RESULTS: Regarding the effects of taste education, scores of food neophobia significantly decreased (P < 0.01) in the posttest, mean (m) score ($4.10{\pm}1.19$) decreased compared to the pretest ($4.39{\pm}1.00$), and WTNF significantly increased (P < 0.001) in the pretest (m) score ($0.48{\pm}0.33$) compared to the pretest ($0.32{\pm}0.34$). This result indicates verification of the study hypothesis. CONCLUSIONS: Food neophobia scale (FNS), an index that measures personal food preference [1,2], showed a very weak correlation with behavioral willingness to taste novel foods (WTNF). Therefore, it is expected that the two scales measure different things. However, considering that the traits of food neophobia are not easily changed, the taste education program was administered in a remarkably effective manner.

The survey was conducted to investigate the perception and purchase behaviors regarding environment-friendly agricultural products (EFAP). 353 questionnaires were collected from college students in Daejeon and analyzed using SPSS 21.0. The students recognized EFAP as foods containing less or no agricultural pesticides and chemical fertilizers. More food major students knew the definition of EFAP compared to non-food major students (p<0.05). The students discriminated EFAP based on certificat on label and obtained information about EFAP from TV/home shopping. More non-food major students purchased EFAP than food major students (p<0.001). The main reason for hesitation with EFAP purchases was the high price. However, students purchased EFAP because of their family's safety. Price reduction is the most important factor to promote the consumption of EFAP. Proper education programs are required so that college students can easily purchase EFAP to promote safe and healthy dietary habits.

This study was performed to assess the perception and need for the elderly meal service program of the Korean elderly. The purpose of this study was to assess the dietary environment factors which are related to the perception and need for such service. Subjects of this study were 800 elderly persons of whom responses were received from 769(male: 26, female: 543) aged over 60 years. Their mean age was 7.51 $\pm$8.1 years. Seventy two point two percent of them lived with their family and 54.5% of them were supported economically by their children. Among their meal management behaviors, food purchasing was hard to perform and the most aid-needed activity. In their dietary environment, 47.1% of them were supported by their children. The percent of the subjects who were aware of the elderly meal service program was 48.4%. Men were more aware of the meal service program than women(p<0.01). Elderly who were supported by government were more aware of this service than others. Elderly who were in poor dietary environment, were less affluent or had trouble preparing meals expressed better perception this service than others (p<0.05). Those who requested meal services had poor dietary environment than those who did not (p<0.001). The elderly who were younger, with higher income, and lived with a spouse had more demand for home delivered meal service. This study showed that the poorer the greater desire for meal services. Therefore, the need for urgent improvement and expansion of meal services for elderly is suggested by this study.

The present paper resents information on the dietary intake and biochemical status of elderly who are living in different types of residence. On hundred and sixty five women(age 65-80 years old) were divided into three groups ; those who are living alone (LA) , living with family (LF) , and living in institutions (LI) within the same general community. Nutrient intake, body fat content, and biochemical measurements in blood and urine were examined statistically and potential environment-related influence are discussed. Elderly women living alone had significantly lower intake of nutrients than elderly women were not living alone LF group showed significantly higher fat consumption than LA and LI groups. Body fat content, plasma albumin and calcium levels in elderly women who lived with other people were significantly higher than those in elderly women living alone, but fat weights and lean body mass between groups were not different. None of the plasma lipid fractions were significantly different among the three groups except LDL-cholesterol (LDL-C) concentration. In the LI group, LDL-C was lower than that of LF and LA groups. From the above results, serious nutritional deficiency has been shown in elderly women that live alone. Therefore, nutritional education and social help should be carried out to improve these situations for elderly people.

The purpose of this study was to compare wage treatment and the employment environment of school foodservice employees before and after conversion to indefinite contract status since September 2012 when the Ordinance on the Appointment of Education Officials (indefinite contract) under the Gangwon Provincial Superintendent of Education was applied as well as to examine the effects of wage treatment and the employment environment on job stability. The questionnaire survey was conducted from March 31 to April 10, 2017 for school foodservice employees working at 97 schools in Gangwon province. A total of 477 questionnaires were distributed and 470 questionnaires were used for the analysis. Statistical analysis was conducted using SPSS Window Ver.18.0. The detailed results of this study were as follows. First, wage treatment (2.29 vs. 3.16), employment environment (3.45 vs. 4.22) and job stability (1.88 vs. 2.35) revealed significantly positive perceptions after conversion to indefinite contract status compared to before conversion. Second, after analyzing leading factors influencing job stability, it was revealed that wage treatment (before: ${\beta}{\hat{a}}=0.516$, P<0.05; after: ${\beta}{\hat{a}}=0.465$, P<0.05) had a positive (+) effect on job stability, whereas employment environment did not affect job stability. In conclusion, in the context that most school foodservice employees are contract employees, this study is significant in that the changes in the employment policies of the national government and education office were confirmed to have effects on school foodservice employees.

The purpose of this study was to estimate the relationships between dietary factors and the stress perception levels of College students. A survey was conducted in June, 2010, targeting 332 college students in Gwangju. General environmental factors, stress perception levels, dietary behaviors, and dietary action guide performance of the subjects were evaluated by questionnaire, and food intakes was determined by the 24-hour recall method. The results are summarized as follows.: The score of frequency experiencing was $45.1{\pm}16.9$ for male students, and $47.0{\pm}16.7$ for female students. The importance scores were $50.8{\pm}18.5$ for males, and $53.3{\pm}18.7$ for females. The total score for dietary action guide performance was $39.6{\pm}7.2$ for males and $40.6{\pm}6.5$ for females. Nutrient intake levels were evaluated based on dietary reference intake (DRI), revealing energy intakes to be 68.5% EER in males and 73.9% in females. The mean intakes of nutrient were 54.2% RI for calcium, 73.6% RI for riboflavin, and 51.2% RI for vitamin C but 203.6% AI for sodium, which indicates an imbalance in nutrient intake. Analysis of the correlations between stress perception levels and dietary factors, scholarship achievements, financial problems, future problems, value senses, and family relationships revealed significant correlations with general environment factors, dietary behaviors, Dietary action guide performance, and nutrient intakes (p<0.05). The higher the stress perception levels of the students, the higher the energy, coffee and alcohol intake, which predicts that appropriate stress control in college students will lead to better dietary habits. It is expected that the results above will be used as basic data for the development of proper nutrition education programs and stress control strategies.

BACKGROUND/OBJECTIVES: Unregulated inflammatory responses caused by hyperglycemia may induce diabetes complications. Hesperetin, a bioflavonoid, is a glycoside in citrus fruits and is known to have antioxidant and anticarcinogenic properties. However, the effect of inflammation on the diabetic environment has not been reported to date. In this study, we investigated the effect of hesperetin on proinflammatory cytokine secretion and its underlying mechanistic regulation in THP-1 macrophages with co-treatment LPS and hyperglycemic conditions. MATERIALS/METHODS: THP-1 cells differentiated by PMA (1 µM) were cultured for 48 h in the presence or absence of hesperetin under normoglycemic (5.5 mM/L glucose) or hyperglycemic (25 mM/L glucose) conditions and then treated with LPS (100 ng/mL) for 6 h before harvesting. Inflammation-related proteins and mRNA levels were evaluated by enzyme-linked immunosorbent assay, western blot, and quantitative polymerase chain reaction analyses. RESULTS: Hesperetin (0-100 µM, 48 h) treatment did not affect cell viability. The tumor necrosis factor-α and interleukin-6 levels increased in cells co-treated with LPS under hyperglycemic conditions compared to normoglycemic conditions, and these increases were decreased by hesperetin treatment. The TLR2/4 and MyD88 activity levels increased in cells co-treated with LPS under hyperglycemic conditions compared to normoglycemic conditions; however, hesperetin treatment inhibited the TLR2/4 and MyD88 activity increases. In addition, nuclear factor-κB (NF-κB) and Acetyl-NF-κB levels increased in response to treatment with LPS under hyperglycemic conditions compared to normoglycemic conditions, but those levels were decreased when treated with hesperetin. SIRT3 and SIRT6 expressions were increased by hesperetin treatment. CONCLUSIONS: Our results suggest that hesperetin may be a potential agent for suppressing inflammation in diabetes.

This study investigates the effect of working hours on the dietary behaviors and dietary quality of male industrial workers employed in rotating shifts. The survey was conducted from February to March 2022, enrolling 209 male workers operating in rotational shifts at industries in the Chungcheongnam-do region. Eating behavior and health awareness were investigated during the morning shift, afternoon shift, and night shift for the same subjects. The shift timings were found to be associated with dietary behavior, which had an impact on the dietary quality of workers. Negative effects of shift timings on diet and health were also perceived by the shift workers. The frequency of alcohol consumption was high during the morning shift, and the frequency of night time snack intake was high during the afternoon shift. During the night shift, there was decreased vegetable intake and increased ramyeon intake. Compared to the morning shift, a significant decrease in dietary quality scores was found during the night shift. The workers recognized that rotating shift work negatively affected health, eating habits and sleep. There was a high demand for providing a variety of menus and healthy night snacks in the company cafeteria. When nutritional counseling and educational health services were provided, the willingness to participate was high. Therefore, to improve the health and dietary quality of shift workers, there is a need to provide diets suitable for the working environment and the characteristics, and to provide nutrition management services.
