Stomach contents of 518 specimens of the yellow goosefish, Lophius litulon caught by the off-shore stownet in the southern waters of Korea were examined by means of the calculation of the frequency of occurrence number and weight percentages, and index of relative importance (IRI) in each prey organisms. Prey organisms of the yellow goosefish consist of fishes, crustaceans, cephalopods. Fishes were dominant prey group, and occupied $98.8\%$ in IRI of prey organisms. Four species of fish, Pseudosciaena manchurica Collichthys niveatus, Engraulis japonica, Trichiurus lepturus were dominant as to the IRI and occupied $87.2\%$ of the total IRI. P. manchurica was a dominant prey organism in predator's stomach through the year, and the other dominant prey organisms occurred intermittently with seasonal progress. P. manchurica was a dominant prey organism to all fish size, too. C. niveatus and E. japonica decreased in importance in the diet as the fish size increased concomitant with an increase in importance of T. lepturus. Mean species number and mean individual number of prey organisms increased with the fish size.

Following breast cancer diagnosis, women often attempt to modify their lifestyles to improve their health and prevent recurrence. These behavioral changes typically involve diet and physical activity modification. The aim of this study was to determine association between healthy eating habits and physical activity with quality of life among Iranian breast cancer survivors. A total of 100 Iranian women, aged between 32 to 61 years were recruited to participate in this cross-sectional study. Eating practices were evaluated by a validated questionnaire modified from the Women's Healthy Eating and Living (WHEL) study. Physical activity was assessed using the International Physical Activity Questionnaire (IPAQ). A standardized questionnaire by the European Organization of Research and Treatment of Cancer Quality of Life and its breast cancer module (EORTC QLQ-C30/+BR-23) were applied to determine quality of life. Approximately 29% of the cancer survivors were categorized as having healthy eating practices, 34% had moderate eating practices and 37% had poor eating practices based on nutrition guidelines. The study found positive changes in the decreased intake of fast foods (90%), red meat (70%) and increased intake of fruits (85%) and vegetables (78%). Generally, breast cancer survivors with healthy eating practices had better global quality of life, social, emotional, cognitive and role functions. Results showed that only 12 women (12%) met the criteria for regular vigorous exercise, 22% had regular moderate-intensity exercise while the majority (65%) had low-intensity physical activity. Breast cancer survivors with higher level of physical activity had better emotional and cognitive functions. Healthy eating practices and physical activity can improve quality of life of cancer survivors. Health care professionals should promote good dietary habits and physical activity to improve survivor's health and quality of life.

To assess the food habits, the nutrient intakes and diet quality of high school students living in Chuncheon area. a dietary survey using a questionnaire and 24hr recall method was conducted with 318 subjects. $30.8\%$ of the subjects often skipped breakfast and $28.0\%$ had snacks over once per day. Mean daily energy intake was $1740\pm712kca1\;with\;61.1\%$ of energy supplied by carbohydrate, $16.0\%$ by protein and $23.1\%$ by fat. As well as insufficiencies in calcium and iron intakes, the bioavailability of calcium and iron consumed is considered to be low because most of them came from plant origins. For calcium, iron and riboflavin, the proportions of subjects with intake levels less than $75\%$ of RDA were all over $68\%$. The mean adequacy ratio(MAR), an index of overall dietary quality was 0.79 for males and 0.78 for females. The indexes of nutritional quality(INQ) were over 1 for most nutrients except 3 nutrients: 0.67 of calcium, 0.82 of iron, 0.90 of riboflavin. Nutrient intake levels less than $75\%$ of RDA may be appropriate as a criteria for insufficiency of nutrient intakes. Based on these results, it is evident that some of high school students in Chuncheon area did not consume enough nutrients, especially calcium, iron and riboflavin.

This study aims at grasping the relativity between laborers' yangseng level and stress so as to present the groundwork for preventive oriental medicine approach in industrial health. The researcher prepared the questionnaire on general character, - health-related yangseng level and chose 632 people to execute Autonomic balance test through heartbeat change. The collected material was analyzed by SPSS and tested by T-test, ANOVA The general yangseng level average is 3.27, morality yangseng 3.91, sleep yangseng 3.39, mind yangseng 3.32, sex life yangseng 3.29, exercise yangseng 3.14, activities and rest yangseng 3.07, diet yangseng 2.95, seasonal yangseng 2.84. The highest is morality yangseng and seasonal yangseng is the lowest. In the aspect of yangseng level: Having a spouse, Non-smoking, Non-drinking, Regular exercising, Sufficient sleeping have higher yangseng levels. In Autonomic balance test, age from 35 to 40 has the highest autonomic activity and job period from 5 years to 10 years has the highest stress resistance. Non-smokers have high autonomic activity and stress resistance. Further, have low autonomic balance, stress index and fatigue strength. In the case of regular exercising person, he/she has high autonomic activity and stress resistance with low stress index. Regarding sleeping time, autonomic balance is the highest when he/she sleeps less than 6 hours. Stress resistance is the highest when he/she sleeps 7 hours and stress index is the highest when he/she sleeps 6 hours. After comparing the relativity between yangseng level autonomic balance test, only exercise yangseng has plus factor on autonomic activity and stress resistance and minus factor on stress index and fatigue strength. Yangseng level has been affected by individual character and daily habits. Also stress is more influenced by daily habits than by individual character. We can find the relativity of exercise yangseng between yangseng and stress which suggests that we need to take measures to win over stresses in individual health in the near future.
Purpose: The consistent rise in the number of foreign students in Korea demands an accurate and detailed investigation into their dietary practices and nutritional status. For these international students, assimilation into new cultures can be stressful. The influence this process may have on dietary behaviors as well as overall health cannot be overlooked. Methods: The researchers in this study sought to investigate the nutritional status and dietary practices of Ghanaian students studying in Korea. A total of 81 Ghanaian male students with an average age of $29.4{\pm}4.0years$ were sampled between May and June 2016. Investigations were carried out on the general characteristics of the participants, their daily food and nutrient intakes using a 24-h dietary recall method, meal skipping practices, and the nutritional quality of their diets based on their meal skipping habits. Results: The study revealed that the daily nutrient intake of subjects did not fully meet the daily recommended nutrient intake (RNI) established by Ghanaian Ministry of Health and the World Health Organization (WHO) and Food and Agriculture Organization (FAO), particularly for energy, calcium, iron, zinc, and vitamin B2 requirements. The Nutrient Adequacy Ratio (NAR) for calcium was very low, posing a deficiency risk to the participants. Meal skipping practices among participants changed significantly after arriving in Korea. The study also compared the diet quality indicators (Nutrient Adequacy Ratio and Mean Adequacy Ratio) of those who skipped meals ${\geq}7times/week$ with those who skipped meals < 7 times/week. Participants who skipped meals ${\geq}7times/week$ were shown to have lower dietary intakes of vitamins B1 and B2 than those who skipped meals < 7 times/week. Conclusion: Ultimately, the study found that meal skipping among Ghanaian students was common, and their daily nutrient intakes did not meet the set dietary standards. Those who skipped meals ${\geq}7times/week$ had lower dietary intakes of vitamins B1 and B2 than those who skipped meals < 7 times/week. Based on our study findings, we recommend that nutrition education should be organized for the Ghanaian student community in Korea using our results as a template to draw up a nutrition program that is culturally appropriate.
The winter ecology of individual yellow-throated martens(Martes flavigula) intemperate region of Korea were studied through snow-tracking. The study was performed across 3 winter seasons, from January 2011 to February 2013. Total distance of 49.8km was snow tracked (comprising 13 snow-tracking routes) to determine winter foraging habits, general behavior and movement paths of solitary and small groups (1-6 individuals; $mean=2.9{\pm}1.6$) of yellow-throated martens. The martens in the current study were omnivorous, with their winter diet including 9 animal and 5 plant species. Yellow-throated martens searched for food near and under the fallen logs and branches, root plates of fallen trees, around the roots of growing trees, and in small holes in the ground. They also climbed trees to search inside the tree holes and vacant bird nests. Foraging activity was estimated to occur at a frequency of 1.20 times/km, while territory marking occurred 1.42 times/km on average. Of the 60 documented foraging activities we observed, 17 were successful (28.3%). Moving activity and territory marking mainly occurred along ridges, whereas foraging activity was recorded in valleys, slopes, and forest edges. To protect the habitat of this species, the entire forest should be preserved, including the valleys, slopes, and even forest edges as well as main ridges.
The aim of this study was to investigate the effect of sleep duration on dietary habits and body composition of university students. Sleep duration has recently been added to the list of risk factors for obesity. However, studies on this topic are fairly limited particularly in Korea. We studied the relationship between the duration of sleep and obesity principally based on body mass index and %body fat in university students. For this purpose, a survey was conducted on a total of 312 university students. The subjects enrolled for this study were divided into two groups: (1) those with sleep duration of <7 hours (148 students) and (2) those with sleep duration of >7 hours (164 students). Based on a self-reporting method, the participants filled up the questionnaires for more than 20 minutes. Based on the overall data obtained, we observed that most students (52.88%) skipped breakfast. This was mainly due to shortage of time (60.58%). We also observed that self-reporting dietary preferences included eating irregular meals (49.04%), overeating (19.55%), imbalanced diet (16.35%), and skipping meals (9.94%). It was found that cookies were the favorite snacks in the majority of the participants (50%). Our data reveal that the body mass index, fat mass, visceral fat, and subcutaneous fat, respectively of the shorter sleep duration group (<7 h/day) were 23.78 $kg/m^2$, 19.13 kg, 2.23 kg, and 11.15 kg. In contrast, in those of the control group (7 h/day), these values were found to be 21.84 $kg/m^2$, 13.88 kg, 1.56 kg, and 12.11 kg. We also observed that there were significant correlations of sleep duration with body mass index (p<0.05), fat mass (p<0.01), visceral fat (p<0.01), and beck depression score (p<0.01). Our data suggest that the body mass index in the shorter sleep duration group was higher than that of the control group; however, %fat, visceral fat, and subcutaneous fat in the shorter sleep duration group were found to be higher than those of the control group. The data obtained through our study suggest that short sleep duration is clearly associated with a modest increase in general and abdominal obesity particularly in university students.
This study was carried out to survey dietary intakes of 739 elementary students, 4-6grades, in Won-Ju area, in 1998, to enhance the effect of school foodservice. The results were as follows : 1. Most investigated students had nuclear family with one brother or one sister. 2. The average height of boys and girls was $141.0{\pm}7.7cm\;and\;141.4{\pm}8.0cm$, and the average weight of them was $35.7{\pm}8.5kg\;and\;36.1{\pm}8.5kg$, respectively. There was no significant difference between boys and girls. 3. The rates of obesity were 12.2% in urban, 7.4% in rural and 0% in remote rural area by Rohrer index and 22.9% in urban 13.9% in rural and 0% in remote rural area by the rate based on standard weight. 4. All nutrients intake of investigated students were sufficient according to recommended dietary allowances. All nutrients intake of boys were higher than those of girls. Calcium intake of children with well educated mother was higher than that of children with poorly educated mother. Children in remote rural area had lower carbohydrate, calory and calcium intake than those in other areas. 5. Students without breakfast had lower protein and iron intake and higher calory from snack than those with breakfast. 6. Students who thought themselves to be obesity had low intake of carbohydrate, total calory and calory from snack and students with regular exercise had high intake of protein, iron, calcium and calory from snack. 7. Students with unbalanced diet, snack intake in large quantities and irregular meal had lower protein, fat, iron and calcium intake and higher calory from snack than other students. As a result, Students without breakfast often had lower all nutrients except calory from snack than other students, significantly. Problems of nutrients intake of elementary students in Won-Ju area were high rate of obesity, high intake of protein, unbalanced nutrients intake of students without meal or students with excessive eating and limited calcium intake of students with poorly educated mother. It is important to confirm desirable food habits for balanced nutrients intake in all areas and to increase calcium intake of students in remote rural area.
The factors for the childhood onset obesity were assessed to provide informations for the nutrition education program targeting the primary school children. The subjects of this study were 529 primary school children in Iksan City, Jeon-buk Province. Children were classified into obese(236) and control(293) groups by the obesity index. Anthropometric measurement dietary intake through 24-hour recall method, blood analysis and questionnaire response including nutritional knowledge and attitude, body image recognition and eating habits were conducted The mean age of subject was 12.0 years. The average body weight(p<0.001), BMI(p<0.001), and obesity index(p<0.001) in obese group were significantly different from those in control group; their values in the former were 26.5 kg/m2 and $37.7\%$ and 43.0 kg, 19.8 kg/m2 and $3.2\%$ in the latter, respectively. The average scores of self-satisfaction were significantly different in two groups (p<0.001), 31.2, and 34.1, respectively. Among the obese subjects, $60.6\%$ were unsatisfied or very unsatisfied with their body image, and $76.5\%$ had experiences of weight control and $67.5\%$ took diet control as a weight control method Among mothers of obese subjects, $89.1\%$ were unsatisfied with their children's body image. $64.4\%$ of obese subjects had obese parents. Average intake of energy were $76.7\%$ of RDA in obese group and $74.9\%$ of RDA in control group. Average intake of cereals(p<0.01), potatoes & starch(p<0.01) and eggs(p<0.01) between obese and control subjects were significantly different; 295.4g, 76.2g, 55.6g in the former and 277.9g, 38.1g, 45.6g in the latter, respectively. The mean serum triglyceride(p<0.05), GPT(p<0.05), hemoglobin(p<0.001) concentration of the obses and control subjects were significantly different; in the former, 103.6mg/dL, 24.6U/L, 13.4g/dL, and in the latter, 93.7mg/dL, 19.9U/L, 13.1g/dL, respectively, The results suggest that practical nutrition education for the prevention of childhood onset obese should be provided to primary school children.
The feeding habits of Coreoperca herzi were investigated from specimens collected in the Geum River, from March to December 2016. The specimens were separated into groups of 38~70 mm, 71~109 mm, and over 110 mm in total length. The live foods of C. herzi included Ephemeroptera, Odonata, Plecoptera, Coleoptera, Diptera, Trichoptera, and fishes. The Korean aucha perches fed mostly on aquatic insects which took up 98.8% of food regarding the number, 55.8% regarding the biomass, and 97.1% in terms of iregarding the index of relative importance. They were carnivorous in diet and predators (stalker) in food intake characteristics and forms when applying Keenleyside's classification. The main food sources of C. herzi were Ephemeroptera, Diptera, and Trichoptera while Odonata, Plecoptera, Coleoptera, and fishes were rare. A food migration was observed since less Ephemeroptera was found and more Trichoptera and fishes were found in the biomass of the feed consumed by larger species. The amount of Coleoptera and Diptera did not change much with the size of the species. The overall composition of live food was not seasonal. The result of the study indicates that, when restoring the streams to be the habitat for the natural population increase of Coreoperca herzi, the environment should be inhabitable to Ephemeroptera, Diptera, and Trichoptera which are the main foods.
