This study was performed to investigate 172 samples of fried food in fast food store. The free fatty acid value of 22 samples exceeded standard of fried-food. These samples were 10 fried chickens, 6 fried potatoes and 5 fried onions. Fatty acid composition differed from each company. The correlation between free fatty acid value and double bond index was very low. New standard of fried food in fast food store is needed for thorough hygiene management, because of being not existed standard. The fried potato containing many carbohydrate and fat appeared higher calory than fried chicken containing many protein. The fried food had high fat comparatively, so that attention in regard to excess intake is demanded. The trace materials were included Mg, Ca, Mn, Fe, Zn, Cu and Cr in order of quantity, and the harmful heavy metals-Pb, Hg and Cd- were included small quantity.

Thermal performance of fusing system in laser printer is determined by FPOT(First print out time) required and toner fusing quality. FPOT is influenced by the thermal resistance of fusing system between heat source and nip region. Also FPOT is depended by the heat source power and toner fusing temperature. The fusing quality of toner is decided by the temperature, pressure and duration time in nip region. In this study, I have performed thermal analysis for the toner fusing system. Computational simulation has been used to understand the effect of heat source power and printing speed etc. on the temperature distribution of the fusing system. Also in order to predict fusing quality, numerical simulation of the process that paper is continuously supplied to the nip regions were performed. In comparison with the experimental results of the fusing quality vs transferred calory to the toner layer, I could evaluate various fusing condition parameters effected on the thermal performance.

Purpose : The rising prevalence of childhood obesity may be due to an energy imbalance between food intake and energy expenditure. Recently, consumption of beverages in children has increased. The aim of this study is to provide useful information for the prevention and the control of childhood obesity by assessment of variable beverage consumption. Methods : Fight hundred seventy seven children(M : F=1 : 1.02, mean age; 9.7 years) from two primary schools in Seoul in May 2003 were enrolled. Body mass index(BMI) was calculated and the degree of obesity was classified into normal, overweight and obese groups by BMI percentile. Parental BMI, socio-economic factor, 3-day dietary intake, calory intake and beverage intake were examined by questionnaires. We researched beverages and classified them into six categories, milk, other milk products, soda, sports beverage, other beverage. Results : The prevalence of obesity was 7.2%. The parental BMI of the obese group were higher than those of the other groups. There was no significant difference in birth weight, or parents' intellectual and economic levels between the obese group and the other groups. There was no significant difference in daily total calory intake between the obese group and the other groups. The obese group of 7-9 year-old-males was higher than the other groups in sodas, and sports beverages intake. The obese group of 10-12 year-old-males was higher than the other groups in total beverage intake and other beverage intakes. The obese group of 10-12 year-old-females was higher than the other groups in other milk products. Conclusion : Excessive intake of beverages is associated with childhood obesity. Efforts to decrease intake of beverages may be important approaches to counter the rise in the prevalence of obesity.

Aging is a senescence and defined as a normal physiologic and structural alterations in almost all organ systems with age. As Leonard Hayflick, one of the first gerontologists to propose a theory of biologic aging, indicated that a theory of aging or longevity satisfies the changes of above conditions to be universal, progressive, intrinsic and deleterious. Although a number of theories have been proposed, it is now clear that cell aging (cell senescence) is multifactorial. No single mechanism can account for the many varied manifestations of biological aging. Many theories have been proposed in attempt to understand and explain the process of aging. Aging is effected in individual by genetic factors, diet, social conditions, and the occurrence of age-related diseases as diabetes, hypertension, and arthritis. It involves an endogenous molecular program of cellular senescence as well as continuous exposure throughout life to adverse exogenous influences, leading to progressive infringement on the cell's survivability so called wear and tear. So we could say the basic mechanism of aging depends on the irreversible and universal processes at cellular and molecular level. The immediate cause of these changes is probably an interference in the function of cell's macromolecules-DNA, RNA, and cell proteins-and in the flow of information between these macromolecules. The crucial questions, unanswered at present, concerns what causes these changes in truth. Common theories of aging are able to classify as followings for the easy comprehension. 1. Biological, 1) molecular theories - a. error theory, b. programmed aging theory, c. somatic mutation theory, d. transcription theory, e. run-out-of program theory, 2) cellular theories - a. wear and tear theory, b. cross-link theory, c. clinker theory, d. free radical theory, e. waste product theory, 3) system level theory-a. immunologic/autoimmune theory, 4) others - a. telomere theory, b. rate of living theory, c. stress theory, etc. Prevention of aging is theoretically depending on the cause or theory of aging. However no single theory is available and no definite method of delaying the aging process is possible by this moment. The most popular action is anti-oxidant therapy using vitamin E and C, melatonin and DHEA, etc. Another proposal for the reverse of life-span is TCP-17 and IL-16 administration from the mouse bone marrow B cell line study for the immunoglobulin VDJ rearrangement with RAG-1 and RAG-2. Recently conclusional suggestion for the extending of maximum life-span thought to be the calory restriction.

Purpose: We studied to know the effect of early feeding on the course and the recovery of acute diarrheal disease. Methods: The study was conducted on 76 patients who admitted to the Soonchunhyang university hospital for acute diarrhea. We divided 76 patients into 3 dietary groups (whole milk group (WMG): 35, diluted milk group (DMG): 29, breast milk group (BMG): 12). We compared three groups by numbers of diarrhea, numbers of vomiting, calory intake, weight increments, and duration of diarrhea. Results: 1) The mean age was $16.45{\pm}18.20$, $11.53{\pm}9.80$, $5.38{\pm}5.01$ months for WMG, DMG, and BMG, respectively. The mean weight was 9 kg and the mean duration of diarrhea was 2.29 days. 2) The numbers of diarrhea during admission was not significantly different in the three groups. 3) The calory intake during admission was significantly low in DMG. 4) The weight increments during admission was significantly low in DMG. 5) The duration of diarrhea during admission was not significantly different in the three gourps. Conclusion: Early refeeding with whole milk or breast milk did not prolong or worsen the course or symptoms of diarrhea compared with gradual reintroduction with diluted milk. But there were advantages of improved nutrition and weight increments. Futher study is necessary to demonstrate the effect of diet according to the causative organisms.

Since a 'Well-being' theme had become an issue in 90's, everyone now care about their health more than ever. Besides, IT has been developed so tremendously that we have various ways to collect up-to-dated information through the internet. There are so many web sites that contain information about health and diet. However, the menus of these web sites are not simplified and the content is too large, so the information we see in those web sites may not be accurate. Also, some information is out-of-dated. In this paper, we propose a web site called 'Calory&Diet' that provides customized information on diet. The characteristics of the web site are as following: First, the menu is so simple that users can easily find information they want. Second, it only provides necessary customized information. Lastly, it uses an open application that helps users always get the latest information without DB updates. With its user friendly menu and feedback information, the proposed web site can be a good advisor for people who want to be healthy. 100 offers the user survey results than existing systems, simple system to 2%, 3% from a custom-related topics, the latest related topics were 3% higher on 5 point scale.

Few studies have conducted the bone health benefits of usual dietary isoflavone intake in Korean college-student women. To elucidate this benefitial effects and correlations between dietary isoflavone and nutrients intake and bone formation marker (ALPase, osteocalcin), questionnaires, anthropometric measurements, serum mineral (Ca, P, Mg) concentrations were analyzed. Fifty three subjects were used in this study. The average age, height, body weight, BMI, body fat content and triceps skinfold thickness were 21.43 year, 161.07 cm, 52.81 kg, 20.48 kg/$m^2$, 20.72% and 17.59 mm respectively. Soy food intake frequencies were soybean > soybean curd > soypaste stew > soybean milk. The average calorie, protein and Ca intake were 1766.21 $\pm62.54 kcal\;66.45\pm2.00 g\;and\; 549.62 \pm 27.55 mg$ respectively. Serum ALPase activity and osteocalcin concentration were 115.74$\pm3.6u/L$ and 7.15 ng/$m\\ell$ respectively. Usual dietary isoflavone intake was positively related to calory, protein, Ca, P intake and serum Ca, Mg concentration. Serum osteocalcin concentration was negatively correlated with isoflavone intake ($r^2$=0.28, p < 0.05). In these results, usual dietary isoflavone can support an additive effect to bone health and Ca nutrition.
