The purpose of this study was to develop Graphic Organizer as Advance Organizer. The 'Menu Planning and Food Selection' unit of second grade middle school Technology & Home Economics(revised curriculum of 2007) was selected as the study subject. The course of abstracting an essential education element got done $3^{rd}$ times. It abstracted the first essential education elements to analyze the presented sentence or a concept with the educational contents factor which is on the achievement standard of the area of dietary life from 5grade to 10grade in curriculum revised in 2007. The first 4 essential education elements selected were superiority and cultural value of Korean traditional meal, preparing a balanced diet for the family, food purchasing, and food selection based on the various information'. It abstracted second essential education elements that it concretized the first content factor on a unit of this study and solved overlapping when it was happened at the first contents factor and made connecting with between grade. The $3^{rd}$ essential education elements abstracted to classify the contents which abstracted essential education elements in second. And, it developed Graphic Organizer on a unit of 'Menu Planning and Food Selection' in eight-grade Technology & Home Economics based on the abstracted essential education elements. Graphic Organizer was developed in according to order of the way for making on a Concept Map of Heo In Sook(2000). Developed Graphic Organizer is all of 10 which are 'nutrition value on food of the season', 'harmony and combination of food', 'natural dressing and a garnish', 'the recipe', 'fermented food', 'a traditional instrument and a vessel', 'actor of food harm', 'present food', 'food quality certification' and 'selecting food with food information'.

The objective of this research was to study the effect of astaxanthin (AST) on growth performance and antioxidant capacity in golden pompano (Trachinotus ovatus) both in vivo and in vitro. In the in vivo study, two diets were formulated with or without astaxanthin supplementation (D1 and D2; 0 and 200 mg/kg) to feed fish for 6 weeks. In the in vitro study, cells from hepatopancreas of golden pompano were isolated and four treatments with or without astaxanthin and $H_2O_2$ supplementation were applied (control group: without both astaxanthin and $H_2O_2$ treated; $H_2O_2$ group: just with $H_2O_2$ treated; $H_2O_2$ + AST group: with both astaxanthin and $H_2O_2$treated; AST group: just with AST treated). Results of the in vivo study showed that weight gain (WG) and special growth rate (SGR) significantly increased with astaxanthin supplemented (P < 0.05). Feed conversion ratio (FCR) of fish fed D2 diet was significantly lower than that of fish fed D1 diet (P < 0.05). Hepatic total antioxidant capacity (T-AOC) and the reduced glutathione (GSH) of golden pompano fed D2 diet were significant higher than those of fish fed D1 diet (P < 0.05). Superoxide dismutase (SOD) was significantly declined as astaxanthin was supplemented (P < 0.05). Results of the in vitro study showed that the cell viability of $H_2O_2$ group was 52.37% compared to the control group, and it was significantly elevated to 84.18% by astaxanthin supplementation ($H_2O_2$ + AST group) (P < 0.05). The total antioxidant capacity (T-AOC) and the reduced glutathione (GSH) of cell were significant decreased by oxidative stress from $H_2O_2$ (P < 0.05), but it could be raised by astaxanthin supplementation ($H_2O_2$ vs $H_2O_2$ + AST), and the malondialdehyde (MDA) was significant higher in $H_2O_2$ group (P < 0.05) and astaxanthin supplementation could alleviate the cells from lipid peroxidation injury. In conclusion, dietary astaxanthin supplementation can improve the growth performance of golden pompano. Moreover, astaxanthin can improve the golden pompano hepatic antioxidant capacity both in vivo and in vitro study by eliminating the reactive oxygen species.

To prepare for the changes in the future, this study considered people in their seventies and eighties in rural areas in the last decade. Based on a survey of rural life by the Rural Development Administration, all factors were analyzed using SAS ver. 9.3. The rate of rice farming decreased, and vegetable-cultivation increased from 8.4% in 2001 to and 26.6% in 2008 for people in their seventies and eighties. The number of family members decreased to 1.96 in 2010 from 2.04 in 2001, and annual income increased by KRW 20-29 million for those in their seventies and eighties, whereas it was more than KRW 30 million for those in their forties. Bathing with warm water increased to 88.9% from 69.8%, and household waste treated by self-incineration decreased from 86.4% to 40.0% in the last decade. Separate collection spread since 2008. Food waste disposal and the burial (46.0%) showed had for people in their seventies and eighties, and animal feed increased (50.7%) for those in their forties at 2001. The separate collection increased by 39.6% in 2010 for those in their seventies and eighties and by 53.5% for those in their forties(p<0.05). The manufacture of jang and kimchi showed were little annual changes for people in their seventies and eighties. Food storage processing was higher for those in their forties. For those in their seventies and eighties, food group intake over the 2004-2010 period increased from 3.3 times a week to 4.2 times a week for protein foods and from 4.9 times a week to 5.5 times a week for vegetables. There was no change in fruits, milk, and seaweeds for those in their seventies and eighties, but there was an increase for those in their forties. The results suggest the continued increase in the manufacture of jang and kimchi and protein and vegetable intake for those in their seventies and eighties. Some direction to welfare, mechanized rice planting and living with neighbors together would be continued with good nutrition for elderly residents.

To examine the relationship between the causal infection of gastric cancer and lifestyle and nutritional status, we surveyed 183 persons, 102 female and 81 male, aged 40 years and over from August to October, 1996, in Chunchon area, Kang Won Do, Korea. For this purpose, we investigated Helicobacter pylori infection in the agricultural Korean adult and identified the effect of sex, age, smoking, alcohol consumption, economic status, occupation and lifestyle. Helicobacter pylori immunoglobulin G(IgG). Helicobacter pylori infection was present in 64.5% of total subjects, and 63.7% of female, 65.4% of male and its prevalence was increased with age, smoking, low education level, low monthly income, high childbirth. Some nutrients intakes were significantly difference between Helicobacter pylori infection positive(+) group and those negative(-) group. The negative Helicobacter pylori infection group were much more intaked energy, total protein, total fat(p<0.05), animal fat(p<0.05), Iron(p<0.001), vitamin A(p<0.01), vitamin C(p<0.05) than Helicobacter pylori positive infection group. But the calcium intakes were lower than positive(+) group.

This study was conducted as a comparative analysis, using the SPSS 17.0 program for a survey conducted from March to July 2013, on the level of perception and preference factors of Koreans and Americans residing in Virginia, USA(89 male and female adults of 20 years of age or above). For the information on the degree of obesity, a survey was used and the subjects provided with their heights and weights. The researcher used this data to calculated their BMI and distinguished the degrees of obesity. For the BMI, the obesity diagnosis of Korean Society for the Study of Obesity was used for Koreans, and the WHO's obesity diagnosis on adults were employed for Americans. First, regarding the Korean participants, the level of obesity appeared in the order of normal (79.6%), overweight (14.3%), and underweight (6.1%). Also, the level of perceptions of their health conditions appeared in the order of average (51.7%) and good (34.7%). No one perceived their health to be in poor condition. Meanwhile, for the American participants, the order was as follows: overweight at about 45%, normal weight at about 35%, obesity at about 12.5%, and underweight at about 7.5%. In terms of the level of perception of health during ordinary times, about 55% of the American participants answered that they are in good health. Therefore, the Americans were found to perceive their health to be in relatively better condition than the Koreans residing in the USA. Also, concerning the level of interest in health while eating food at ordinary times, the American participants were discovered to be more interested (about 62.5%) than the Korean participants. The research on their preference for salty taste was conducted as a survey, and the subjects were asked to choose an item according to their subjective feeling. Regarding the preference for salty taste, both Koreans and Americans residing in the USA responded as moderate. However, a higher proportion of Americans than Koreans responded to favor salty taste. Concerning the reason for their preference for salty taste, Koreans responded with various reasons whereas Americans mostly responded that it is because they eat salty food frequently. For any changes in dietary behavior related to eating salty food, both Korean and American respondents thought that the amount of their daily intake of salt is appropriate and that they consider taste as most important in selecting a snack. Based on the above data, the results of this research indicate a need for actual improvement in the diet with regard to salty food along with diverse policies for promoting life with a low salt diet in future.

Objective: PCOS is one of the most common endocrine disorder affecting reproductive age women. It shows wide range of reproductive and metabolic manifestations. This study was to determine the differences of clinical and laboratory characteristics between adolescent and adult Korean Daegu Kyungpook PCOS patients. We also compared clinical and laboratory values of Korean PCOS patients to Turkish and American PCOS patients. Methods: 88 cases were diagnosed and enrolled as PCOS patients, based on 2003 Rotterdam criteria, who visited KNUH Reproductive Endocrinology division between Jan. 2000 and Apr. 2008. We retrospectively reviewed clinical characteristics, serum hormone levels, ultrasono-graphic findings. And we divided into 2 groups, adolescent and adult. We analyzed them with Chi-square test and Student's t-test statistically. Results: There were no statistically significant differences between adult and adolescent Korean PCOS patients. The prevalence of hyperandrogenism such as facial acne or hirsutism, obesity, and insulin resistance of Korean PCOS women was significantly lower than Turkish and American PCOS women. Conclusion: From the results of this study, we can suggest that it is sure that there are differences of clinical and laboratory characteristics of PCOS patients between races. Genetic background, dietary habits and life style affect the expression of clinical symptoms of PCOS. But we could not find out the difference between adolescent and adult PCOS patients of same race. It might be due to the limitation of small patient number and narrow range of age distribution. So, there must be large scale and multi-center and multi-regional study.

Recently, the cardiovascular disease has increased by causes such as westernization dietary life, smoking, and obesity. In particular, the acute myocardial infarction (AMI) occupies 50% death rate in cardiovascular disease. Following this trend, the AMI has been carried out a research for discovery of risk factors based on national data. However, there is a lack of diagnosis minor suitable for Korean. The objective of this paper is to develop a classifier for short-term relapse mortality prediction of cardiovascular disease patient based on prognosis data which is supported by KAMIR(Korea Acute Myocardial Infarction). Through this study, we came to a conclusion that ANN is the most suitable method for predicting the short-term relapse mortality of patients who have ST-segment elevation myocardial infarction. Also, data set obtained by logistic regression analysis performed highly efficient performance than existing data set. So, it is expect to contribute to prognosis estimation through proper classification of high-risk patients.

Objectives : The aim of this study was to evaluate the relation between the state of dental health(number of natural teeth) and nutritional status of Korean elderly using Korean Dietary Reference Intakes, which was an objective standard for nutritional intake based on database of Korea National Health and Nutrition Examination Survey, large scale of sample obtained by the government. Methods : Complex sampling procedure was used to analyze the fourth data(2007-2009) of Korea National Health and Nutrition Examination Survey. When preparing planning file, the estimator of variance as a stratification variance (variance name : kstrata), population of survey unit as a cluster variance(variance name : PSU), and previous exam and nutritional related weighted as a weighted were analyzed by considering reproduced survey and nutritional related total weighted. Complex samples chi-square test was used to estimate the relation between number of natural teeth and inadequate intake and relation factors included in the model were analyzed by complex samples logistic regression analysis. Results : The group of edentulous had a higher risk to intake less nutrient, except calcium, riboflavin and vitamin C than recommended level comparing to reference group which had natural teeth more than 20(phosphate : OR=1.763; 95% CI=1.273-2.443, thiamine : OR=1.748; 95% CI=1.276-2.395, protein : OR=1.610; 95% CI=1.213-2.138). Conclusions : The number of teeth in Korean elderly over 65 years old had a relation with nutritional status in this investigation. Especially, intake level of nutrients was different between the edentulous group and the reference group. Therefore, dental health care is needed from young and middle age to keep health dental condition for through whole life as well as old age. Although the dental condition of the aged is not good, it is evitable to educate them about the relation between dental health and nutritional ingestion to take balanced nutrition, we think.
