This study was carried out to compare the dietary behaviors and the nutrient intake of a middle school and a high school girls in Iksan. The subjects consisted of 132 middle school girls and 122 high school girls in Iksan. The proportion of subjects eating meals irregularly was higher in the high school girls (98.6%) than in the middle school girls(78.7%). The proportion of subjects skipping a meal also was higher in the high school girls(61.5%) than in the middle school girls(53.8%) and most of them (65.8%) skipped breakfast though they thought breakfast was the most important meal of a day (87.4%). The subjects tended to overeat at lunch (38.6%), and at dinner (55.9%). The main reasons of skipping a meal were 1. They had no time (49.3%), and 2. They had poor appetite (24.7%) Mean daily energy intake was 2198.5Kcal in the middle school girls and 2150.5Kcal in the high school girls and mean daily intake of protein, iron, vitamin $B_1$, vitamin $B_2$ and niacin was significantly higher (p<0.05, p<0.01) in the middle school girls than in the high school girls. Mean daily calcium, iron, vitamin $B_1$, vitamin A and C intake of middle school girls were lower than those of RDA and all nutrients intake of high school girls except for phosphorus was lower than those of RDA. The index of nutritional quality (INQ) was under 1.0 for calcium, iron, vitamin A, $B_1$ and C. Mean blood level of cholesterol, triglyceride, Hb, Hct, GOT, GPT were 170.9mg/dl, 78.9mg/dl, 13.1g/dl, 39.5%, 18.8mg/d and 15.7mg/dl, respectively.

This study was carried out to determine the depression symptoms and nutritional status of elderly females that ate congregate meals at lunch in rural Pocheon. The subjects were 18 elderly females aged over 65 ($75.7{\pm}4.6$ years) and information on smoking, subjective health status, depression symptoms and malnutrition risk were collected using a questionnaire administered with the help of trained research assistants. Measurements included mid-arm circumference and calf circumference. Food consumption for 3 days during breakfast and supper were determined by 24-hour recall and food consumption at lunch was determined as the difference between the amounts served and the plate waste. All data were compared between two age groups (${\leq}75$ and > 75). The subjects had the lowest nutrient adequacy ratio (NAR) for vitamin $B_6$ (0.523), followed by calcium and niacin and the lowest index of nutrient quality (INQ) for calcium (0.738). The older elderly had significantly lower NAR for vitamin $B_1$, vitamin $B_2$, vitamin $B_6$ and niacin as well as significantly lower mean adequacy ratio (MAR) compared to the young elderly. They also had significantly lower INQ for vitamin $B_1$ and vitamin C and significantly thinner arm circumference (28.3 cm vs. 31.3 cm). They consumed more than 40% of their daily intake for each nutrient at lunch. Higher proportions of nutrient intake from lunch provided evidence of the importance of congregate meals, suggesting that the government and society should support congregate meals to improve nutritional status.

The study was performed to investigate the relationship of regular exercise to body composition and nutrient intakes of male college students by comparing anthropometric measurements and one-day dietary intakes by 24-hour recall of physical education (PE) majors and non-major male college students. The subjects were 253 students residing in the Gyeonggi area. Only 64.1% and 32.1% of PE majors and non-major students exercised over 4 times a week and PE major students did stronger exercise than the non-major students did. Mean BMI and WHR (Waist Hip Ratio) of the two groups were not different. But percentages of body fat and lean body mass in PE major students were lower and higher, respectively, than those of non-major students. PE major students consumed significantly more energy and other nutrients except iron, niacin, vitamin C, and vitamin E than non-major students. Nutrients consumed less than KRDA was calcium in PE major students and energy, calcium, zinc, vitamin $B_{12}$, folate, and vitamin C in non-major students. Mean adequacy ratio (MAR) of PE major students (1.00) was significantly higher than that of non-major students (0.94). Index of Nutritional Quality (INQ) of all nutrients except vitamin A of PE major students was also significantly higher than that of non-major students. Nutrients below 1.00 in INQ of both groups were calcium, zinc, vitamin B2, and folate. Our data supports that regular exercise may positively influence on body composition and increase diet quality in male college students. Therefore, an educational program focused on regular exercise along with proper dietary behavior would be needed.

Objectives: The objective of this study was to revise the target pattern in food guidance system for adolescents' balanced menu planning. Methods: The food groups in the target pattern were divided into detailed food items, and intake number were assigned to each food items based on the revised standard food composition table. The validity of revised target pattern was examined. Menu planning according to the revised target pattern was made available to 305 male and female middle school students and the nutritional assessment of the menu plan were carried out using SPSS WIN 12.0. Results: The energy contents, energy contribution ratios of carbohydrate, fat, and protein, and 4 minerals' and 6 vitamins' contents of the revised target pattern were adequate. The average energy contents of the menu planned according to revised target pattern were 400~500 kcal higher than that of the revised target pattern when the revised standard food composition was applied. The energy contribution ratios of fat were 28.9%, close to maximum of acceptable macronutrient distribution range (AMDR) (30%), and that of carbohydrate were 54.5%, lower than minimum of AMDR (55%). The nutrient adequacy ratios (NARs) of calcium and vitamin C were less than 1.0. According to index of nutritional quality (INQ) of food items, kimchi, milk dairy products, and soybean curd were energy efficient source for calcium, kimchi, fruit, vegetable and seaweed were energy efficient source for vitamin C, with INQ of food items were higher or close to 2.0. Kimchi was the best energy efficient source of calcium and vitamin C. Conclusions: Revised target pattern based on the adolescent's foods intake was not good enough for balanced menu planning by adolescents, because what they ate and what they wanted to eat were very much different. Detailed guidance for food selection is necessary in each food items.

This study was conducted to examine the nutritional status, quality of diet and quality of life in postmenopausal women with mild climacteric symptoms based on their food group intake patterns. The data for nutritional status were obtained using 3-day records. Quality of diet was assessed by INQ, NAR, MAR, DDS, DVS, DQI-I. Climacteric symptoms were analyzed by the questionnaire of Kupperman's index and MENoL. The subjects were classified into the five groups, GMVDF, GMVdF, GMVDf, GMVdf, GmVDF according to their food group intake patterns. Analysis of nutrient intakes showed that the GMVDF group took significantly higher levels of kcal, carbohydrate, protein, fat, vitamin A, thiamin, riboflavin, folate, vitamin C, vitamin E, calcium, phosphorous, sodium, iron, zinc and fiber than GMVdf group did (p < 0.05). INQ of Ca and Fe appeared to be higher in GMVDF than in GMVdf groups (p < 0.05). Analysis of NARs showed that missing milk groups took lower riboflavin, Ca and P than other groups did as the same result with MAR (p < 0.05). Analysis of DDS and DQI showed that GMVdf group had the lowest quality of diet (p < 0.05); however, no difference was found on DVS. The GMVdf group showed the worst climacteric symptoms compared with those of the other groups (p < 0.05). However, we couldn't observe any differences in menopause-specific quality of life among the groups. In conclusion, it would be beneficial to meet all five food groups to increase the quality of diet and to reduce the climacteric symptoms in postmenopausal women.

Comparative studies regarding the nutritional status of 93 home-living elderly people taking free congregate lunch meals(FL) and 87 middle income class elderly people(MI) were performed in Taejon city. Data was obtained from questionaires, anthropometry and interviews for the 24-hour dietary recall of 2 nonconsecutive days during August, 1996. The average age for FL was 75.8 years. The monthly familly income for FL belonged to the low-income class. FL females had lower heights and weights than MI females. The average daily nutritional intake of both FL and MI were low, particularly in FL whose %RDA of energy was 68.5%, protein 65%, Ca 29.6%, Fe 50.8%, vitamin A 34.5%, vitamin E 30.5%, riboflavin 40.6%, vitamin C 76.9%. MI's %RDA of energy was 76.4%, protein 80.a2%, Ca 48.1%, Fe 78.6%, vitamin A 67.3%, vitamin E 117.4%, riboflavin 45.6%, vitamin C 136.5%. Comsumption of Zn, vitamin $B_6$ and folic daily average. There was no nutrient having average INQ(Index of nutritional quality) over 1 for either group. The INQs for protein, Ca, Fe and vitamin A were 0.802, 0.377, 0.625 and 0.296 in FL, and 0.900, 0.601, 0.784 and 0.602 in MI, respectively. The MAR(Mean adequacy ratio) was low with the value of 0.500-0.518 in FL and 0.630-0.723 in MI. The percentage of main nutrients from lunch was the highest among the three meals for FL males, while that from breakfast was the highest for MI. Free lunches taken by FL supported higher percentages of main nutrients than home-lunches taken by MI. Eating-out was done more frequently by MI than by FL and that eating-out brought them more nutritional intake. The above data indicated that the dietary nutritional intake status of the FL elderly was very poor in both quantity and quality and that free congregate lunch significantly contributed to the daily nutrient-intake for the FL elderly.

BACKGROUND/OBJECTIVES: This study investigated gender and age differences in nutrient intake and dietary quality of people eating alone. SUBJECTS/METHODS: From Korean National Health and Nutrition Examination Survey 2013-2016 data, 2,305 adults aged 20 years and older that ate meals alone were included in this study. Their energy and nutrients intakes, as well as their nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ) were analyzed. Food group consumption pattern, dietary variety score (DVS), dietary diversity score (DDS) were also analyzed. All data were compared among gender and age groups. RESULTS: Men consumed more energy and nutrients than women, except for vitamin C, and the NARs showed similar gender differences. The INQs of 4 nutrients (calcium, vitamin A, vitamin C, and riboflavin) were lower than 1.0 in men, whereas only the calcium INQ was lower than 1.0 in women. Men had a lower DDS (3.6) than women (3.9) (P < 0.001) and had more 'undesirable' food group consumption patterns than women (P < 0.001). The intakes of calcium, vitamin A, and vitamin C were relatively low in the young-aged group (INQs less than 1.0). In the old-aged group, the MAR level was relatively low, and the INQs of calcium, riboflavin, and niacin were below 1.0. The old-aged group consumed more menu items, but their DVS was the lowest. CONCLUSIONS: Compared to women, the dietary quality and food diversity among men were poorer. There were poorer quality and diversity patterns in the young-aged group compared to those of the older groups. An overall low intake of nutrients and the low nutrient density of meals were the main dietary problems among the old-aged group who eat alone. Therefore, men, particularly young- and old-aged, need to be prioritized in nutritional policies directed toward those who eat alone.

본 연구에서는 2008~2009년도 국민건강영양조사 자료를 활용하여 45~60세 중년여성을 대상으로 주관적 건강상태에 따라 대상자를 분류하여 그룹 간에 생활습관, 건강특성, 영양소 섭취량 및 식사의 질에 차이가 있는지 비교하고, 주관적 건강상태와 식사의 질과의 관계를 살펴보았다. 조사대상자의 평균 나이는 $52.1{\pm}4.6$세였고, 교육수준과 월 평균 소득은 주관적 건강상태가 '좋음' 군에서 유의적으로 높았다(P<0.05). 주관적 건강상태가 '나쁨' 군의 허리둘레가 유의적으로 더 컸으며(P<0.05), 체지방률, 체질량지수는 주관적인 건강상태에 따라 유의적인 차이가 없었다. 신체활동에서도 주관적 건강상태가 '좋음' 군에서 일주일간 걷기 일 수와 신체활동 일 수 모두 유의적으로 많았다(P<0.01). 영양소 섭취량 분석 결과 주관적 건강상태가 '좋음' 군의 철(P<0.01), 인(P<0.05), 칼륨(P<0.05)과 비타민 A(P<0.05), 비타민 $B_1$(P<0.01), 비타민 $B_2$(P<0.05), 나이아신(P<0.01)의 섭취량이 유의적으로 높았다. NAR을 평가한 결과에서도 '좋음' 군의 단백질(P<0.05), 칼슘(P<0.05), 철분(P<0.05), 비타민 A(P<0.05), 비타민 $B_2$(P<0.05), 나이아신(P<0.01)의 NAR이 유의적으로 높았으며, MAR도 '좋음' 군에서 유의적으로 높았다. 단백질(P<0.05), 철(P<0.05), 비타민 $B_1$(P<0.05), 나이아신(P<0.05)의 INQ 또한 '좋음' 군에서 유의적으로 높았다. 식사의 질과 주관적 건강상태 관련성을 알아보기 위해 회귀분석을 실시한 결과 교란 인자를 보정한 후에도 MAR과 INQ는 주관적 건강상태와 유의적인 양의 관련성(P<0.001)을 보였다. 이상의 결과로 높은 식사의 질이 자기가 인식하는 주관적인 건강상태에 긍정적인 영향을 미칠 수 있으며, 중년여성의 식사의 질이 주관적 건강상태와 관련이 있는 만큼 이들 여성의 건강 증진을 위해 바람직한 식습관을 통한 식사의 질을 높일 수 있는 구체적인 식사 지침 및 식생활 교육이 마련되어야 할 것으로 사료되는 바이다.

We report on the synthesis and film formation on a variety of small molecules such as $Alq_3$, $Znq_2$, and $Inq_3$, used as light emitting material in organic light emitting diodes (OLEDs) . The organic materials are usually susceptible to environmental aging and photo-oxidation, which influences their viability for commercial utility. Here, we examine the effects of oxygen and light on these organic materials to enhance the efficiency and lifetime of OLEDs. Optical techniques - ellipsometry, photoluminescence and infrared spectroscopies- have been used to study of environmental and light induced effects on 8-hydroxyquinoline derivative metal complex small molecules thin films
