Background: Sea turtles, which are globally endangered species, have been stranded and found as bycatch on the Korean shore recently. More studies on sea turtles in Korea are necessary to aid their conservation. To investigate the spatio-temporal occurrence patterns of sea turtles on the Korean shore, we recorded sampling locations and dates, identified species and sexes and measured sizes (maximum curved carapace length; CCL) of collected sea turtles from the year 2014 to 2020. For an analysis of diets through stomach contents, we identified the morphology of the remaining food and extracted DNA, followed by amplification, cloning, and sequencing. Results: A total of 62 stranded or bycaught sea turtle samples were collected from the Korean shores during the study period. There were 36 loggerhead turtles, which were the dominant species, followed by 19 green turtles, three hawksbill turtles, two olive ridley turtles, and two leatherback turtles. The highest numbers were collected in the year 2017 and during summer among the seasons. In terms of locations, most sea turtles were collected from the East Sea, especially from Pohang. Comparing the sizes of collected sea turtles according to species, the average CCL of loggerhead turtles was 79.8 cm, of green turtles was 73.5 cm, and of the relatively large leatherback turtle species was 126.2 cm. In most species, the proportion of females was higher than that of males and juveniles, and was more than 70% across all the species. Food remains were morphologically identified from 19 stomachs, mainly at class level. Seaweeds were abundant in stomachs of green turtles, and Bivalvia was the most detected food item in loggerhead turtles. Based on DNA analysis, food items from a total of 26 stomachs were identified to the species or genus level. The gulfweed, Sargassum thunbergii, and the kelp species, Saccharina japonica, were frequently detected from the stomachs of green turtles and the jellyfish, Cyanea nozakii, the swimming crab, Portunus trituberculatus, and kelps had high frequencies of occurrences in loggerhead turtles. Conclusions: Our findings support those of previous studies suggesting that sea turtles are steadily appearing in the Korean sea. In addition, we verified that fish and seaweed, which inhabit the Korean sea, are frequently detected in the stomach of sea turtles. Accordingly, there is a possibility that sea turtles use the Korean sea as feeding grounds and habitats. These results can serve as basic data for the conservation of globally endangered sea turtles.

The aim of this study was to determine the association between, smoking, exercise, sex, and dietary carotenoids ($\alpha$-carotene, $\beta$-carotene, $\beta$-cryptoxanthin, lutein + zeaxanthin, lycopne) intake in Korean middle-aged adults. Food-frequency questionnaire were analyzed from 304 healthy adults (115 men, 189 women) aged 20 - 59. The self-administered questionnaire contained subject s habitual diet and alcohol intake were the previous 3 months. Data on frequency of 102 foods, including vegetables, fruits, beverages and legumes were analyzed. Total dietary carotenoids intake were 27.13 $\pm$ 3.09 mg/d for men and 26.71$\pm$ 2.82 mg/d for women. It was found that smoking had no significant contribution to the dietary intake of carotenoids. Among other lifestyle factors that had significant correlation was the amount of exercise time. The increases in exercise time was associated with increase in carotenoids intake (r= 0.121, p : 0.04). The major contributors of $\alpha$-carotene and $\beta$-carotene were carrots consumed as single-food item or carrot juice. Lutein and Zeaxanthin intake mainly came from spinach and most lycopene intake was derived from tomato products not fresh tomatoes. Persimmon was the major contributor of $\beta$-cryptoxanthin. These findings provide valuable information on understanding the unique pattern of dietary intake of Korean, which might help identify the risks for developing various diseases.

This study was conducted to examine the association of dietary behaviors, serum lipid profiles according to the progression of angiographically evaluated atherosclerosis. The subjects were 32 male patients aged 59-80 yrs living in the Daegu area who underwent initial angiography for their lower extremities. We classified the subjects into two groups according to the seriousness of iliac lesions based on angiographic results : Group I (lower lesion group) and Group II (higher lesion group). Dietary habits were evaluated by 10-item questionnaires. Daily food intake of each subject was assessed by the 24-hour recall method. There were no significant differences in serum cholesterol and triglyceride levels between the two groups. The food habit score of Group II was significantly lower than that of Group I (P<0.001). Group II showed significantly lower dietary habit scores in the consumption of fish and bean product (P<0.001), seaweed product (P<0.01), and salt use (P<0.001) than those of Group I. Dietary intake of vitamin C was significantly lower in Group II (P<0.01). Our results indicate that the more serious of atherosclerotic lesions the patients had, the poorer dietary habits they exhibited. Therefore, medical nutrition therapy for atherosclerotic patients should emphasize maintaining a balanced diet by consuming more fishes, beans, and seaweed as well as by reducing salt intake.

This study examines the relationship between food purchase accessibility for 86 homemakers and that for 42 grocery stores. The Study area included Bibong-myeon and Maesong-myeon, Hwaseong-si, Gyeonggi-do, to represent a rural area. The analysis classified three regions (residence, outside of residence, and other areas) and seven types of grocery stores (LDS, CS, NCS, CC, NCC, TM, and other). The expansion of the area range increased the availability of food items and the accessibility of large-scale grocery stores as well as those for food procurement. The respondents had difficulty preparing family meals and buying food items because of a lack of food item variety and the small scale of grocery stores. In particular, fresh meat, fruits, and fish were difficult to purchase, causing some nutritional imbalance. These results suggest a need to develop meal composition samples and programs that can actively encourage the intake of meat and fish products with a diet based in self-produced vegetables for better dietary behaviors.

The aim of this study was to develop and apply a list of meals and standard recipes using barley for diabetic patients. The degree of interest and requirements of diabetic patients were investigated for the development of meals. The ingredients of the meals were selected through the diabetic literature and previous research. While developing a list of meals, dietetic therapies for diabetic patients were considered. After developing 15 kinds of meals and modifying them through sensory evaluation, a standard recipe was completed. In the standard recipe, the menu name, the ingredients, quantity, and recipe were stated and the nutritional components were indicated. Photographs of the meals were included. The calorie prescription for the diabetic patients was aimed at elderly women, that is, those 65 years old or above, based on research showing this to be the average age of diabetics. The prescribed calories were 1,500 kcal based on the food exchange list. Weekly lists of meals including the developed dishes were made for diabetic patients. The list were modified after consultation with a clinical nutritionist. When completed, one meal item was selected for each day and cooked. A photograph was taken and presented diabetic patients. This article presents the standardized recipes of the developed list of meals and applies them to modifying the diabetic diet, with an aim to be of service to diabetic patients attempting to meet their dietetic therapy goals. We also provide basic data on institutional food services for diabetic patients and nutrition education.

This study was performed to identify the health behaviors and medication compliances of hypertensive patients in a rural area, from May 1 to July 31. 2001. The subjects were 100 hypertensive patients who were registered at the Health Center in Goeje City. The data was collected by face-to-face interviews with a 25-item questionnaire on health behaviors, and analyzed by the Chi-square test on each variable. The results were as follows: Approximately 76% of the subjects were currently taking drug medication. In the comparison of health behavior rates between male and female, there were statistically significant differences in smoking (p< .000), alcohol(p< .003), low salt diet(p< .014), and the health behavior rates of female were higher than those of male. In the comparison of socioeconomic factors by medication compliance, there was statistically significant difference in sex(p< .001), and the medication compliance rate of female was higher than that of male. In the comparison of subjects' perception by medication compliance, there were statistically significant differences in seriousness of hypertension (p< .001) and medication period for hypertension care (p< .004), The medication compliance rate of the group of subjects who took the threat on their hypertension seriously was higher than that of the group who didn't, and the medication compliance rate of the group who knew that they should take medication for the rest of their life was higher than that of the group who didn't. These results suggest that community health education programs and distribution of information must be emphasized in order to increase medication and to encourage behavior changes for promoting health.

A food frequency questionnaire (FFQ), which can be used in studies investigating relationship between diet and chronic diseases in a rural area of Korea, was developed and validated. Food items were selected from two sources ; (1) preliminary survey in a rural area by 24-hour recalls and (2) National Nutritional Survey of 1991. Sixty-five food items were finally selected based on the frequency of consumption and contributions to major nutrient intakes. Portion size of each food item was determined considering the mean and median values of the amounts consumed by subjects in the preliminary survey. Frequency of consumption was asked in nine categories ranging from 'more than three times a day' to 'almost never'. The newly developed FFQ was administered in 24-hour recalls conducted in different seasons in the same area after the administration of FFQ. Sixty-one subjects completed both FFQ and all three repeated 24-hour recalls. The results of the two different survey methods showed that mean daily intake levels of energy, carbohydrate, vitamin A and vitamin C were significantly higher in FFQ compared to 24-hour recalls(p<0.05). Intake levels of energy, protein, fat, carbohydrate and iron were significantly correlated by Pearson's correlation coefficients(p0.05). Ranking on nutrient intake of the subjects by two method were significantly correlated(Spearman's correlation coefficients) in all above nutrients plus Ca and vitamin A. Percentage of subjects in the lowest or in the highest quintile by 24-hour recalls who belong to the nearest two categories by FFQ ranged from 46% to 83%, while the percentage falling into the opposite category were below 10% in most of the nutrients. The proportion of subjects classfied into the same quintiles by the two methods were between 23% and 33%, with an average of 28%. From the results, FFQ developed in this study seems to be useful in evaluating nutrient intake pattern of 1 year in adults living in rural area of Kyonggi province.

BACKGROUND/OBJECTIVES: This study aimed at evaluating the dietary intakes of Korean adolescents affected by food insecurity, in comparison with those who were food secure. SUBJECTS/METHODS: The study used one day 24-hour dietary recall data from the $6^{th}$ Korea National Health and Nutrition Examination Survey. The study subjects consisted of 1,453 adolescents of whom 695 were middle school-aged and 758 were high school-aged. Food security status was assessed using the 18-item questionnaire. Nutrient intake was evaluated in terms of nutrient density, insufficient intake, and excessive intake for selected nutrients, in addition to meeting the appropriate range for total energy intake and energy intakes from carbohydrate, sugar, protein, fat, and saturated fatty acids. Food intake was evaluated in terms of food group servings and dietary diversity score (DDS). RESULTS: The percentages of food insecurity were 11.1% for middle school-aged adolescents and 16.8% for high school-aged adolescents. Food insecure middle school-aged adolescents had higher intake of carbohydrate (P = 0.006) but lower intake of fat (P = 0.010) and saturated fatty acids (P = 0.005) than their food secure counterparts although the intake of both groups was in the recommended ranges. Nutrient intake among high school-aged adolescents was generally similar regardless of food security status. Both food secure and insecure adolescents showed insufficient intake of vitamin A, vitamin C, and calcium, and excessive sodium intake. They additionally had low prevalence of meeting appropriate intake ranges for energy, carbohydrate, and sugar. Food intake in terms of food group servings and DDS was also similar regardless of food security status among both age groups, with low intakes of foods from fruit and dairy groups. CONCLUSIONS: Except for a few nutrients among the middle school-aged adolescents, dietary intakes among Korean adolescents did not differ by food security status in this study.

This study was conducted to develop and evaluate the reliability and the validity of a questionnaire in order to determine the applicability as a screening tool for estimating environmental exposure and health effects related to air pollution. The questionnaire was developed with adopting some items of others such as ISAAC or ATS-DLD. And then we performed test-retest to 89 middle school students and their mothers at interval of three months. Cohen's Kappa values, weighted Kappa values, Spearman's correlation coefficients, and Pearson's correlation coefficients for each item were computed as reliability coefficients. The validity coefficients and validity coefficient bounds were also obtained by simply using these reliability coefficients. As results, Kappa ranged broadly from 0.10 to 0.61 of the items 'diet', $0.52\sim0.79$ of the environmental tobacco smoke, $0.39\sim0.44$ of the functional categories of surrounding environment, and $0.39\sim0.44$ of the using transportation systems; these items were regarded as confounding factors. For items related to health outcomes, Kappa ranged from -0.02 to 0.37 in the respiratory system of past medical history, and from 0.11 to 0.55 in the current health status. But Kappa of the others were over 0.60. In conclusion, if some items can be corrected or modified, the questionnaire developed in this study can be used as a tool for evaluating environmental exposure and health effects associated with air pollution.

This study investigates the effects of serving medicinal food items on the dietary intake of elderly inpatients. A total of 77 elderly inpatients at a long-term senior care hospital in Yeongju participated in this study. Control and medicinal food items were provided for 20 days (March 24 through April 12, 2014, and April 14 through May 3, 2014, respectively). A satisfaction survey was conducted for both control and medicinal food items on the last day of the respective serving period. Data were analyzed by using SPSS (Windows ver. 21.0). The satisfaction level was higher for medicinal food items than for control food items. The leftover rate was higher for control food items than for medicinal food items. The intake of energy, carbohydrates, proteins, fats, vitamin A, thiamin, niacin, potassium, and zinc was higher for medicinal food items than for control food items. These results indicate that the dietary intake of elderly inpatients was higher for medicinal food items than for control food items. This suggests that medicinal food items can help increase the nutrient intake of elderly inpatients and implies that such food items may be more desirable for a long-term senior care hospital diet. A prospective analysis of the long-term control is needed to establish the effects of medicinal food items on elderly patients.
