A human being's pursuit is that of a better quality of life and the disabled naturally want to do so. But challenged people's lives have not improved apace with the general development of our society as a whole. Specially, in a patriarchal society like Korea, challenged women are in a less favorable situation. Challenged women can enjoy more healthy and more happy life in a given condition. Thus, in this research, we closely examined the women's general characteristics, disabled characteristics, health condition(subjective health condition, experiences of diseases, stress value, etc), satisfaction value of life who have handicaps of limb or/and body. On the 17th of September through the 14th of October '98, a nation-wide retardation compaign was held and 200 people were served by telephone. Then we analysed primary factors on quality of life. As results, monthly income, how they think of their economic level, their subjective health condition, and the stress level that the success depends on self influenced quality of life.

The current socioeconomic climate has meant more children spend more time alone at home even for dining. This study was performed to characterize modem Korean childrens´food ecology based on mealtime atmosphere. A total of 705 elementary school students, 347 girls and 358 boys took part in the study. They were chosen evenly from the Seoul metropolitan areas, provincial cities, or rural areas, and were asked to fill out a questionnaire. The questionnaire was categorized to determine various factors related to food ecology, life styles, and health related symptoms. The average age of the study subjects was 11.5 years. The average height, weight, body mass index, and Rohrer index were 143.2cm, 37.6kg, 18.2 and 127.2 respectively. A significant number of children(39.2%) answered their bed time was between 11 and 12 pm. Only 28.3% answered that the whole family has breakfast together, and 47.7% have dinner together. A considerable number of children, 17.8% for breakfast and 6.9% for dinner, answered they eat alone. Most of the children answered they like to have dinner with the whole family. Half of the children answered they do not feel hungry before having breakfast. Proportions of children for their favorite meal time were 66.8%, and 25.4% and 7.8% for dinner, school lunch, and breakfast respectively. The largest proportions of children, 53.3% and 68.7%, have breakfast and dinner at home. Most of the children(75.2%) never purchase their dinner. Forty two% of the children answered they like school lunch, however, 60% of children answered they leave portions of lunch uneaten occasionally or always. Only 38.0% and 46.2% of the children have nutritionally adequate diet for breakfast and dinner. Children having more meals with the whole family possessed a more positive attitude towards breakfast compared to the children who eat with the whole family less frequently. In conclusion, Korea children are exposed to different health threatening food ecology problems related to changing environments, and consistent concern and support from community nutritionists are required.

This study was performed to evaluate chromium in air and chromium concentrations in whole blood and urine of workers at chrome plating factories, and to determine the correlation between environmental and biological chromium levels. This study involved 29 workers as study group and 24 undergraduate students as control group. The geometric means(GM) of airborne hexavalent chromium and total chromium concentrations in the plating factories were 3.4 $\mu\textrm{g}$/㎥ and 10.8 $\mu\textrm{g}$/㎥, respectively. Hexavalent chromium levels in two of total 29 measurements exceeded the korean occupational exposure limit and the American Conference of Governmental Industrial Hygienists Threshold Limit Value(ACGIH-TLV) of 50$\mu\textrm{g}$/㎥. Only one sample for total chromium exceeded the Korea occupational exposure limits, the ACGIH-TLV, and the National Institute for Occupational Safety and Health Recommended Exposure Limits(NIOSH-REL) of 500 $\mu\textrm{g}$/㎥. The GM of chromium concentrations in blood and urine of workers exposed to chromium were 8.4 $\mu\textrm{g}$/L and 11.9 $\mu\textrm{g}$/L. The GM of chromium concentrations in blood and urine of workers exposed to chromium were 8.4 $\mu\textrm{g}$/L and 11.9 $\mu\textrm{g}$/L, respectively, whereas the chromium concentrations in blood and urine of the controls were 1.6 $\mu\textrm{g}$/L and 3.8 $\mu\textrm{g}$/L, respectively. There were statistically significant differences of blood and urine concentrations between study group and control group (p<0.01). The chromium concentrations in urine were most highly related to hexavalent chromium, concentration in air(r=0.642, p<0.01). Also, there was a relatively high correlation between the hexavalent chromium concentrations in air and chromium concentrations in whole blood(r=0.557, p<0.05). These results indicate that whole-blood chromium with urinary chromium could be an indicator of chromium body burden caused by exposure to chromic acid mist in plating operation.

The objective of this study was to clarify whether there are any differences between normal and over-weight adults in their perceived weight, health status, health conception and health promoting behavior. The sample consisted of 238 normal weight and 106 over-weight(11% above on the Body Index Scale) adults, more than 20 years-old, who live in Seoul metropolitan. One participant per household was selected for conveneience. The findings from this study are summarized below. 1) Among 106 overweight adults, 30 were above 20% on the Body Index Scale and 11 were above 30%. Twenty-one(19.8%) of the overweight group and 34(14.4%) of the normal weight group had one disease, and there were 30(28.3%) in the overweight group and 46(19.6%) in the normal weight group where one of the family members had a disease, but these differences were not statistically significant. The average monthly family income for the overweight group was \2,220,000 compared to \2,070,000 for the normal weight group, and this difference was statistically significant. The age range for the whole group was between 20 and 74(mean=35.6 for total, 39.4 for overweight and 34.0 for normal weight group). Again significant difference was found. Occupations were salaryman(57.6%), teacher(7.4%), student(5.4%) and others(27.3%). Fifty-six salaryman(70.0%) from the overweight group and 92(52.0%) from the normal group did not consitute a statistically significant different. For the educational status, 90(87.5%) of the overweight adults and 222(93.7%) of the normal weight group finished high school or more educational courses, and there was significant statistical difference. Ninety-two(86.8%) of the overweights and 156(65.5%) of the normal weight group were married, and again significant statistical difference was found. 2) A test for difference in health characteristics between the two weight groups indicated that two groups did not show statistical differences in their perceived health status, health conception or health promoting behavior. That is, the overweight group also perceive their health status as good as the normal group, and regard 'Health' as a state that enables them to carry out social roles and functions rather than as the traditional concept of health as no disease or no symptoms. Both group showed slightly high level of health promoting behavior. To determine if no statistical difference might be related to the overweight group's failure of perceive themselves as overweight, the perceived and objective overweight status were compared by the Pearson Correlation Analysis, and a strong corelationship was found(r=.76, p=.000). That is, if participants perceived themselves as overweighted, they thought and replied to be got more weight comparing to the other person who are in same age and sex. However, 43(18.1%) of the normal group perceived themselves as being overweight and 28(26.4%) of the overweight group thought they were of normal weight. Even though the overweight group employed in this study perceived themselves as being overweight, they regarded themselves as healthy as those in the normal weight group. It was shown that there was no statistical difference between the two groups in health conception, health status and health promoting behavior. 3) Perceived health conception was shown to be significantly related to health promoting behavior(r=.20, p=.004 for whole group ; r=.27, p=.009 for overweight group ; and r=.21, p=.001 for normal group). It means that in both group the higher perceived health conception level, the more frequent health promoting behavior. And, perceived health status was also shown to be significantly related to health promoting behavior(r=.16, p=.000) as a whole and especially for overweight group(r=.24, p=.018), but no significant relationship for normal group(r=.08, p=.620). 4) By means of multiple regression analysis, health conception, perceived health status, age, sex and marital status provided predicted 15.18% on health promoting behavior.

Purpose: The whole body scan in Nuclear Medicine is a widely accepted examination and procedure. Especially, it is mainly used in bone, I-131, MIBI, and HMPAO WBC scans. The diverse uses of the whole body scan range from the HMPAO WBC scan with a speed of 13cm/min, to a whole body bone scan using the Onco. Flash technique with a speed of 30cm/min. The accuracy of table movement has a strong correlation with the image quality, and inaccuracy of speed could negatively affect the image quality. The purpose of this study is to evaluate the accuracy of the table movement while considering the influence of the age of the equipment and the variability in the weight of the patients. Material and Methods: The study was conducted using two of Seoul Asan Medical Center's SIEMENS gamma cameras which are commonly used in our whole body study. The first one is the oldest gamma camera, an ECAM plus (installed in 2000), and the last is brand new one, a SYMBIA T2 (installed in 2008). Three trials were conducted with the tables moving at a different speed each time; 10, 15 and 30 cm/min. The tables' speeds were measured by checking how long it took for the table to move 10cm, and this was repeated every 10cm until the table reached 100 cm. With an average body weight of the patients of about 60~70 kg, the table speed was measured with weights of 0 kg, 66 kg and 110 kg placed on the table, then compared among conditions. Results: The coefficient of variance (CV) of the ECAM plus showed 1.23, 1.42, 2.02 respectively when the table movement speeds were set at 10, 15, and 30 centimeters per minute. Under the same conditions, the SYMBIA T2 showed 1.23, 1.83 and 2.28 respectively. As table movement speed more, the variance of CV as the speed increases. When the patient body weight was set to 0, 66 and 110kg, the CV values of both cameras showed 0.96, 1.45, 2.08 (0 Kg), 1.32, 1.72, 2.27 (66 Kg) and 1.37, 1.73, 2.14 (110 Kg). There was no significant difference (p>0.05) in 95 percent of confidence intervals and measured CV values were acceptable. However, the CV value of the SYMBIA T2 was relatively larger than the ECAM plus. Conclusion: The scan speed of the whole body scan is predetermined based on which examination is being performed. It is possible for the accuracy of the speed to be affected, such as the age of the equipment, the state of the bearings or the weight of a patient. These factors can have a negative impact on the diagnostic consistency and the image quality. Therefore, periodic quality control should be needed on the gamma cameras currently being used, focusing on the table movement speed in order to maintain accuracy and reproducibility.

This study was conducted to assess diet-related health appraisal for cardiometabolic diseases of the college students in Gyeonggi-do. The survey data obtained by 21 questionnaire(6 general characteristics and 15 food behaviors) given to 90 students, 41 males and 49 females. The average age of the subjects was 22.2 years old for the male students and 20.9 years old for the female students(p<0.001). Among the subjects, 35 males and 47 females' height, weight and percentage of body fat were measured using bioelectrical impedance(Inbody 720). The average height, weight, Body Mass Index and percent body fat of the subjects were 175.7cm, 69.5kg, 22.4 and 16.9% for males and 162.0cm, 53.5kg, 20.4 and 27.7% for females, respectively (p<0.001). Male students had a higher prevalence of smoking compared with female students(p<0.001). Females had higher intake frequency of fruits than males(p<0.05). Males had higher intake frequency of fishes than females(p<0.05). Male students had higher number of side dishes at mealtime compared with female students. There were no difference between the sexes in intake frequency of dairy, ramyeon, rice with whole grain, 3-layered pork belly, processed meat, soft drinks, soy products and fast food. Also, there were no difference between sexes in number of vegetables per day, frequency of eating out, prevalence of eating kimchi at every meal. Cardiometabolic risks were calculated by 'Diet-related health risk appraisal'. Male students had higher cardiometabolic risks(hypertension, hyperlipidemia, diabetes, obesity, abdominal obesity) than female students(p<0.001). Appropriate nutritional education for college male students may help to prevent cardiometabolic diseases in the future.

Objectives: The purpose of the study was to investigate the influencing factors of oral health-related quality of life in social workers. Methods: A self-reported questionnaire was completed by 240 social workers in Gwangju by convenience sampling method. The questionnaire consisted of general characteristics of the subjects(age, monthly salary, smoking, alcohol consumption) and systemic health condition(systemic diseases, medication, oral health status, and stress). The factors associated with oral health-related quality of life included skin dryness, eye dryness, lip dryness, and nasal dryness. The subjective dry mouth consisted of 6 questions measured by visual analogue scale(VAS). Cronbach's alpha was 0.868 in the study. The data were analyzed for t-test, one-way ANOVA and multiple regression analysis using SPSS 18.0 program. Results: The oral health-related quality of life in social workers varied by age, oral health status, stress status, and halitosis. The oral health-related quality of life had positive correlations with the subjective perception of dry mouth and whole body dry symptoms. The health status(${\beta}=-0.410$) had the influence on the oral health-related quality of life, nasal dryness(${\beta}=0.230$), age(${\beta}=0.189$), and halitosis (${\beta}=0.162) in order. Conclusions: The oral health-related quality of life was closely related to the health status and nasal dryness. It is necessary to develop the quality of life improvement programs including oral health prevention and care program in the social workers.

With the increasing number of women involved in social activities, beauty industry has flourished. More women than ever before are concerned about make-up, hair care, skin care, and weight control, etc. With the success and commercialization of beauty industry, unconfirmed beauty care services have been introduced in the market. However, the health hazard from diverse beauty care services has not been systematically addressed. This study has the following two purposes: 1) to examine the utilization pattern of diverse beauty care services; and 2) to examine the health hazard from beauty care services. For this study, two major universities located in Seoul area were selected. While 450 female college students were selected from one women's university, the other 450 were from mixed university. Using survey questionnaire, we interviewed with 900 female college students. The results are as follows: As for the beauty care patterns, makeup accounted for 78.6％, Skin care 49.5％, weight/body control 32.0％, hair care 81.5％, and cosmetic operation 14.9％, indicating significant high rates of makeup(x2=9.215, p=0.002) and hair care(x2=4.435, p=0.035) at both mixed and women's universities. The health hazard was measured using four questions. The past studies have not paid special attention to the methodological issue of how to ask health hazard. Depending on how to ask health hazard, the percentage of respondents reporting health problems varied. When the respondents were asked whether or not they had suffered health problems for a short period, over 60％ of respondents reported health problems; when they were asked in other ways-1) whether or not they had suffered health problems for a long period, 2) whether or not they had suffered whole body problems, 3) whether or not they had permanent traces on skin due to beauty care activities-, the percentage of respondents reporting health problems dropped substantially to less than 10％, This finding indicates the importance of ‘words’ used in questions. The relationships between health problems and utilization of beauty care services were examined, using χ2 test or t test. We found that there was a significant relationship between health problem and beauty care.

This study was designed to describe the effect of the protein quality at different intake level of protein on the protein metabolism in the whole body of growing pigs with a simulation model. Varying to the protein level in feeds, four simulations were conducted. The feed protein level, represented as proportions of digestible protein to the metabolic energy (DP/ME, g/MJ), were 6-8, 11-13, 17-19, and 23-25 DP/ME, respectively. Two protein quality and six weeks of growth time were used at each simulation. The objective function for the simulations was protein deposition in the whole body, which was calculated from the experimental results. The parameters in the simulation were determined by the parameter estimation technique. The results obtained from the simulation were as follows: The protein synthesis and breakdown rates(g/day) in the whole body was increased with the increase of protein quality only at lower or required level of protein intake. They showed a parallel behavior in the course of growth, irrespective of quality and level of feed protein intake. The simulated protein deposition and protein synthesis showed a linear relationship between them at different protein quality and level. The affinity parameter showed a linear relationship between them at different protein quality and level. The affinity parameter showed that arginine, tryptophan and isoleucine were more efficient in the stimulation ofbody protein synthesis. Lysine and phenylalanine+tyrosine were less efficient. The oxidation parameter showed that histidine, pheyalanine+tyrosine were less efficient. The oxidation parameter showed that histidine, phenyalanine+tyrosine, and methionine+cystine were oxidized in larger magnitude than lysine and threonine. The oxidation parameter of most amino acids increased with the increase of protein intake beyond the requirement level, but not any more at highest protein intake level. Finally it was found that the improvement of feed protein quality at the lower or required level of protein intake increase protein deposition through a parallel increase of protein synthesis and breakdown.

The food and nutrition system is a network of processes linking agriculture, food, eating, nutrition, and health. The system includes a series of nine stages (production, processing, distribution, acquisition, preparation, consumption, digestion, transport, and utilization) and two types of contexts (biophysical and sociocultural). Analysis of whole food and nutrition systems provides information about the structure and processes involved in the complete scope of food and nutrition, assisting in the identification of ″upstream″ influences and ″downstream″ consequences in the system. The current analysis gathered existing data about the food and nutrition system in South Korea from public sources and professional publications, and interpreted that information to consider how different elements of the system contribute to health. The findings revealed that South Korea has substantial domestic food production and processing supplemented by imports, widespread food distribution in markets and a growing number of Korean and Western restaurants, a relatively low percentage of household income spent on food, growing use of new food preparation methods such as microwave ovens, a rice/vegetable/fish based three-meal consumption pattern, few recorded digestive problems, increasing calorie storage as body fat, and a relatively low chronic disease prevalence compared to other developed societies. Examination of the full scope of the food and nutrition system provides a broad perspective using whole system thinking that can identify potential strategies for future research and intervention.
