The Breakfast Club of the Seoul Metropolitan Government aims to provide breakfast and nutrition education to students who require need breakfast. This study was conducted to explore the experience of changes at the individual and environmental levels among high-school participants of the Breakfast Club. The qualitative data were collected from 20 high school students (10 boys and 10 girls) via a focus group interview at each school. Experienced improvement and suggested future tasks from the experience of the Breakfast Club were categorized at three levels (themes): personal factors, school environmental factors, and home environmental factors. The health belief, knowledege, awareness, and perception of effects of the participants showed improvement but the personal barriers need to be improved. At the school level, peer influence and school food policies were improved but some aspects of availability and accessibility for breakfast, and social norms need to be improved. The factors related to the home environment, such as family influence, and availability and accessibility for breakfast were better after the program. The Breakfast Club changed not only personal behaviors but also the family and school environments.

Occurrence and prevalence of Marteilioides chungmueasis have been reported in several waters around Tongyeong but no report has been made for Pukman bay. Therefore, we investigated that the prevalence and infection intensities in Pukman Bay at the inside and the outside areas which are hydrographically divided by tidal current. Furthermore, various environmental parameters were investigated in order to elucidate effective parameter for parasitic infection. Infection rates of Marteilioides chungmuensis in adult oysters were ranged 3.3-20.0% at the inside area during September 2002 through January 2003, and 3.3-30.9% at the outside area during August 2002 through January 2003. External manifestation of infected oyster consisted of abnormal egg masses with nodular appearance in the soft tissue. Histopathological symptoms included massive hemocytic infiltration within or around the follicle wall and atrophic epithelium of digestive diverticula. For the environmental parameters, comparative study made differences between two side of the Bay during the infection period: inside > outside for SS while inside < outside for chlorophyll-a. A positive relationship was observed between chlorophyll-a and infection period, which might indicate the difference in food availability between two areas. The prevalence of ovarian parasite Marteilioides chungmuensis, therefore, was highly associated with food availability. Pearson's correlation analysis was made between environmental parameters and infection prevalence. Significance was observed in water temperature (p < 0.05), suspended solids (p < 0.01) and chlorophyll-a (p < 0.05). A principle component analysis showed that infection of the ovarian parasite, Marteilioides chungmuensis, exhibited effects of seasonality (component I = 55.2%) and chemical/physical environmental factors (component II = 24.4%). These results clearly indicate that the infection of ovarian parasite, M. chungmuensis in the Pacific oyster Crassostrea gigas is closely associated with seasonality and food availability.

The rapid rise in the incidence of obesity has emerged as one of the most pressing global public health issues in recent years. The underlying etiological causes of obesity, whether behavioral, environmental, genetic, or a combination of several of them, have not been completely elucidated. The obesity epidemic has been attributed to the ready availability, abundance, and overconsumption of high-energy content food. We determined here by Pearson's correlation the relationship between food type consumption and rising obesity using the loss-adjusted food availability data from the United States Department of Agriculture (USDA) Economic Research Services (ERS) as well as the obesity prevalence data from the Behavioral Risk Factor Surveillance System (BRFSS) and the National Health and Nutrition Examination Survey (NHANES) at the Centers for Disease Control and Prevention (CDC). Our analysis showed that total calorie intake and consumption of high fructose com syrup (HFCS) did not correlate with rising obesity trends. Intake of other major food types, including chicken, dairy fats, salad and cooking oils, and cheese also did not correlate with obesity trends. However, our results surprisingly revealed that consumption of com products correlated with rising obesity and was independent of gender and race/ethnicity among population dynamics in the U.S. Therefore, we were able to demonstrate a novel link between the consumption of com products and rising obesity trends that has not been previously attributed to the obesity epidemic. This correlation coincides with the introduction of bioengineered corns into the human food chain, thus raising a new hypothesis that should be tested in molecular and animal models of obesity.

In this study, to improve the quality of school lunch in local colleges, we conducted a survey on students who attend 2 year colleges in Jeju region. With its own unique regional characteristics and the change of its school lunch program from direct management to consignment, there were some questions about how each factor in school lunch program affects on students' satisfaction with it and we tried to present helpful data to improve school lunch programs in each region. The survey took place from May 5 to May 10, 2005 covering the colleges only in Jeju region. There were 200 sets of questionnaires issued and distributed to the students who are currently using school lunch programs. Only 168 sets were retrieved and processed statistically. 2 sets out of 168 questionnaires had to be thrown away because there were wrong entries of some questions, which made overall retrieving rate 83%. In this study, SPSS 10.0 , one of the statistical package programs, was used as an analyzing tool to make Frequency Analysis. To verify credibility, Cronbach's Alpha Element Analysis was done and T-test and ANOVA was also made. After Recurrence Analysis for elements of satisfaction regarding main factors that is considered to be important to customers, we found that importance of following factors: appearance of food, incongruity between main and side dishes, availability of seasonal food, availability of preferred menu, absence of food stock, waiting time, accessibility of food counters, space between chairs, presentation of a menu, food tray's shape, and color of food trays. The importance of those showed high but satisfaction with the same factors was low. So the primary improvement on these factors should be made to increase satisfaction. Finally we concluded that in large extent, importance of each factor definitely affects on students' satisfaction.

해조류는 다당류인 수용성 식이섬유와 무기질의 공급원으로 그 필요성이 증대되고 있다. 그러나 인간이나 단위 동물에 있어서는 해조류의 세포벽물질을 분해할 수 있는 효소를 갖고 있지 않은 것으로 알려져 있어 이에 결합된 무기질은 인체 내 소화가 대부분 되지 않는다. 따라서 본 연구는 해조류의 무기질 함량을 측정하고, 해조류 다당류인 세포벽 물질(NDF, netural detergent fiber)에 결합된 다량 무기질인 Ca, P, Mg을 측정하여, 원래 해조류에 함유되어 있던 무기질 함량에서 NDF에 결합된 무기질의 함량을 감한 후 계산하여 실질적인 해조류의 무기질 추정 이용률을 산정하였다. Ca과 Mg의 경우, NDF에 결합된 무기질의 평균 함량은 각각 77.59, 45.62 mg/100 g NDF로 모두 96% 이상의 높은 추정 이용률을 보였고, P의 경우에는 NDF에 결합된 무기질의 함량이 많아 그 추정 이용률은 73.24%로 비교적 낮았다. P의 경우, NDF에 결합된 함량이 비교적 높았지만 70% 이상이 실질적으로 소화되어 이용가능하며, Ca과 Mg은 모두 96% 이상의 높은 추정 이용률을 보여 대부분의 무기질이 실질적으로 소화되어 이용되는 것으로 보인다. 따라서 해조 다당류인 수용성 식이섬유와 무기질의 급원으로 알려진 해조류는 인체 내의 소화율을 고려한다고 하더라도 무기질의 높은 이용률을 보일 것으로 판단되어 무기질의 급원으로 그 이용이 기대된다. 더욱이 해조류는 한국인에게 부족한 영양소로 주목 받는 Ca을 가장 많이 함유하고 있으며 동시에 그 추정 이용률이 90% 이상으로 높아 Ca의 공급원으로써 해조류의 이용을 기대하며, 추후 추정 이용률을 토대로 소화율을 고려한 무기질의 생체이용률에 관한 연구가 활발히 진행되어야 한다고 사료된다.

The influence of the social changes on the food and nutritional status of Korean during the late period of Joseon Kingdom (1800-1910) was analysed by using old literatures and the records of the Westerners visited Korea during the period. The late period of Joseon can be designated the most poor and miserable period in the history of Korea. The people suffered from the corrupted and incompetent government and social disturbances. The main driving forces to reforming the society at that time were 'Silhak' (Practical Learning), introduction of Catholic church and Donghak movement. The food related literatures written in this period in Korea described the life of upper classes (Yangban) and paid little attention to the life of the poor majority. This paper introduces the food availability and habits of Korean observed by the Westerners visited Korea at that time.
