The purpose of this study was to provide a reference range for plasma homocysteine and to explore the relation between plasma homocysteine and nutritional indexes in a Korean college women. Thirty women were selected from college students in Seoul area With mean age of 22.4y. Dietary intakes of Vitamins B$_{6}$, B$_{12}$, folate were estimated from a 3 day food diary method and plasma homocysteine concentration was mearsured as well as the levels of blood vitamins. The results obtained are as follows. Mean daily intake of energy, vitamin B$_{6}$, B$_{12}$, and folate were 1731.9kcal, 0.9mg, 2.2mg and 139.8$\mu\textrm{g}$ respectively. Mean plasma homocysteine concentration was 12.4$\mu$mol/l with a range between 6.7 and 17.8$\mu$mol/l and the mean concentrations of plasma vitamin B$_{6}$(PLP), serum vitamin $_{12}$, Serum folate and RBC folate were 77.5nmol/l, 267.4pmol/l, 17.1 nmol/l and 736.5nmol/l arid 736.5nmol/l respectively. we found a negative correlation between plasma homocysteine concentration and dietary vitamins, and blood levels of vitamin although it was not significant.
This study was carried out to investigate the Ca and Mg supplementation on the serum and liver lipid parameters in ovariectomized and Ca deficiency rats. Total 50 Sprague Dawley female rats (6 weeks) were divided into 5 groups and bred for 12 weeks: sham operated control group (SNCa), OVX Ca deficiency poop (OLCa) with Ca deficiency diet (0.1% Ca modified AIN-93N diet), OVX Ca deficiency & Mg supplement group (OLCaMg), OVX adequate Ca group (OACa; 0.5% Ca AIN-93N diet) and OVX adequate Ca & Mg supplement group (OACaMg). There were no significant difference among the five groups in serum total cholesterol, triglyceride and HDL-cholesterol levels. LDL-cholesterol of OVX groups was significantly higher than that of SNCa group (p < 0.01). AI (Atherogenic index), TPH (Total cholesterol/HDL-C) and LPH (LDL-C/HDL-C) of OACa group were significantly lower than those of OLCa groups. OACaMg group had significantly lower levels LDL, AI and TPH than OLCa group. There was no significant difference in lever cholesterol level. However, liver total fat content of OACa was significantly lower than that of OLCa. From the above the results, it is concluded that the accumulation level of calcium shows how the supplement of magnesium affects hyperlipidemia. Therefore, in order to prevent women#s hyperlipidemia after menopause, and to keep healthy, it is encourage able to consider how the supplement of magnesium relates calcium intake.
Objectives : The purpose of this study was to investigate how the play habits, temperament, and environmental factors might affect childhood obesity. Methods : Two hundred sixty children, aged 4 through 6 years living in Seoul & Cheonan were surveyed by a questionnaire about the children's play habit and the parent's related factors such as weight, height, education, income. In addition the Korean version of the Parent Temperament Questionnaire for Children and the Korean version of the Family Environment Scale were also administered to parents of those children. The height and weight of those children were measured and the percentage of body fat was measured by Bioelectrical Impedance Fatness Analyzer. Result : 1) Among 260 children, 25 children were considered to be obese on the basis of both obesity index and percentage of body fat. 2) Parents of obese children showed a significantly higher educational level(p<0.05) and mothers of obese children had significantly more jobs(p<0.05) and showed higher body mass index(p<0.05) than those of nonobese children. 3) By observing play habits of children, obese children spent significantly longer time in watching TV and video(p<0.05), while nonobese children showed a trend to play outside(p<0.1). 4) On the Korean version of the Parent Temperament Questionnaire for Children, obese children showed significantly less activity than nonobese ones(p <0.05). 5) Family of obese children had significantly higher point on subscale of Achievement orientation, Intellectual-cultural orientation and Moral-religious emphasis of the Korean version of the Family Environment Scale(p<0.05). 6) Percentage of body fat of obese children was correlated with children's watching TV time, activity level, scores of Achievement orientation, Intellectual-cultural orientation of the Korean version of the Family Environment Scale and the both parent's education levels(p<0.05). Conclusion : Obese children showed hypoactivity and more watching TV time. And obese children's both parent had higher educational level and their mother had higher Body Mass Index and more jobs. Family of obese children had higher point on items of Achievement orientation, Intellectual-cultural orientation and Moral-religious emphasis. Family environmental factors influence on children's obesity through interaction of genetic and behavioral-psychological factors concomittently.

Purpose : Rotavirus is the main cause of infantile diarrheal disease worldwide, especially in patients 3-24 months of age. Infants younger than 3 months of age are relatively protected by transplacental antibody. So the purpose of this study is to evaluate the clinical features and severity of neonatal rotaviral gastroenteritis less than 1 month of age. Methods : A retrospective chart review was established of 62 neonates less than 1 month of age and with a diagnosis of rotaviral gastroenteritis who had been admitted to Pochon CHA University between June 2002 through July 2004. The rotavirus was examined by stool latex agglutination. Results : During 2 years, the total number of admitted patients for rotaviral gastroenteritis was 688 and among these, less than 1 month of age accounted for 9%(62). The occurrence was generally even distribution from January to July($7.14{\pm}1.0$) but since then decreased($2.4{\pm}1.8$). The most common chief complaint was mild fever(46%) when admitted which subsided within 1 hospital day in most patients. 4 patients had seizure and cyanosis with no typical symptoms of rotaviral gastroenteritis. During admission, all the patients had diarrhea. 17% of the patients had leukocytosis and positive C-reactive protein. In one patient, stool occult blood test was positive but there was no necrotizing gastroenteritis evidence. The mean period of hospital day was $5.8{\pm}2.5$ and breast-milk feeding was 62.9%. Conclusion : Neonatal rotaviral gastroenteritis is not a rare disease. Most patients have fever and diarrhea and improve through conservative therapy but a few patients may have severe complications so we must be more cautious about the hygiene for prevention.

Background : Anemia is still the most common nutrient deficiency worldwide, especially in adolescence because of an insufficient supply of iron, an increased iron requirement due to accelerated physical growth and blood loss due to menstruation in girls. This study was designed to assess the anemia and serum iron status of middle school girls. Methods : Hematologic examinations, physical examinations and questionnaires were performed for middle school girls in 1990, 1997, 1999 and 2000. Anemia was defined as a serum hemoglobin level of less than 11.5 g/dL. Iron deficiency was defined as a serum ferritin level of less than 10 ng/mL. Iron deficiency anemia was defined as anemia plus one of the following; MCV less than 78 fL, Ferritin level less than 10 ng/mL or Transferrin saturation rate less than 10%. Results : There was no significant difference in mean Hb between urban and rural areas and decreases in mean Hb as with age. The prevalence of anemia decreased by year; 13.5% in 1990, 6.9 % in 1997, 6.0% in 1999, and 5.7% in 2000. It was high in high school girls(10.1% in 1997 and 12.6% in 2000). The prevalence of iron deficiency decreased by year; 36.1% in 1990, 13.9% in 1997, 13.3% in 1999, and 23.2% in 2000. It was 21.3% in 1997 high school girls and 37.8% in 2000. The prevalence of iron deficiency anemia(IDA) decreased by year; 10.0% in 1990, 4.6% in 1997, 8.3% in 1999, and 6.1% in 2000. It was 11.6% in 1997 high school girls and 18.6% in 2000. Conclusion : Although the prevalence of iron deficiency decreased during this period, the prevalence of anemia in the elder adolescence girls was high. Two things are recommended; first, it is necessary to screen for anemia in middle school girls and high risk groups, second, it is important to evaluate the knowledge of nutrition and to enforce effective nutritional education, leading to subjects receiving adequate nutrition.

The productionof the highly relible softwae systems and theirs performance evaluation hae become important interests in the software industry. The software evaluation has been mainly carried out in ternns of both reliability and performance of software system. Software reliability is the probability that no software error occurs for a fixed time interval during software testing phase. These theoretical software reliability models are sometimes unsuitable for the practical testing phase in which a software error at a certain testing stage occurs by causes of the imperfect debugging, abnornal software correction, and so on. Such a certatin software testing stage needs to be considered as an outlying stage. And we can assume that the software reliability does not improve by means of muisance factor in this outlying testing stage. In this paper, we discuss Bavesian software reliability growth modeling and estimation procedure in the presence of an imidentitied outlying software testing stage by the modification of Jehnski Moranda. Also we derive the Bayes estimaters of the software reliability panmeters by the assumption of prior information under the squared error los function. In addition, we evaluate the proposed software reliability growth model with an unidentified outlying stage in an exchangeable model according to the values of nuisance paramether using the accuracy, bias, trend, noise metries as the quantilative evaluation criteria through the compater simulation.

Purpose: This study investigated the relationship between vitamin D level and dyslipidemia in Korean adults aged 19 years and older. The data for analysis were obtained from the sixth Korea National Health Nutrition Examination Survey 2013 and 2014. Result: This study showed that 74.4% of the specified adult population had vitamin D deficiency. Moreover, the prevalence of dyslipidemia was found to be 39.6% in the same population. Dyslipidemia differed significantly according to gender (p<0.001), age (p<0.001), smoking status (p<0.001), subjective health status (p<0.001), BMI (p<0.001), blood pressure (p<0.001), FBS (p<0.001), physical activity (p<0.001), and vitamin D level (p<0.001). When vitamin D deficiency was less than 20.0 ng/mL, there was a significant risk of dyslipidemia with an odds ratio of 1.29 (95% Cl, 1.11-1.51). The relationship between vitamin D level and a diagnosis index of dyslipidemia with controlled status of physical activity was statistically significant; in Korean adults, the odds ratio for total cholesterol was 1.41 (95% CI, 1.04-1.81) and for triglyceride was 1.36 (95% CI, 1.11-1.66). Conclusion: Our results showed the relationship between vitamin D level and dyslipidemia was significant in Korean adults, and total cholesterol and triglycerides, which are indicators of dyslipidemia, was significant. Future studies, such as a more systematic cohort study investigating the relationship between vitamin D level and dyslipidemia may be helpful in confirming the causal relationship between vitamin D and dyslipidemia.

The purpose of this study was to investigate the treatment status and its related factors of the newly detected rural hypertensives through community health promotion program. A questionnaire survey and blood pressure measurement were performed to 6,977 residents of a rural area, and 282 hypertensives detected by blood pressure measurement were selected as subjects of the study. The study employed the health belief model as a hypothetical model. The major results of this study were as follows: The proportion of person experienced treatment among hypertensives was 12.0%. Treatment experience rate was significantly related with age and educational level(p<0.01). That is, if they were older, lower educational level, the treatment experience rate was higher. The major reasons of no treatment were 'they had not hypertensive symptoms ' (45.6%), 'their blood pressure was not high so much that they received treatment ' (43.2%). The chief facilities for treatment were public health institutions(57.9%) such as health center and health subcenter, and hospital/ clinics(29.8%). The treatment experience rate was higher when they had higher perceived severity for hypertension, lower perceived barrier to treatment, although statistically not significant. Treatment experience rate was significantly related with cues to action and health education experience(p<0.05). That is, if they had hypertension related symptoms such as headache previously, patients suffered from hypertension complication and health education experience for hypertension, the treatment experience rate was higher. In multiple logistic regression analysis for treatment experience, having a cerebrovascular patient in their acquaintance and the experience of health education for hypertension were significant variables. On consideration of above findings, it would to be essential to provide knowledge about hypertension and its treatment, and severity of hypertension complications through health education.
Of the many pathogenic Candida species, Candida albicans is the main fungal pathogen of humans. The oral environmental factors considered in the Candida albicans colony forming unit test contain both host and microbial factors associated with candidiasis. In particular, Candida biofilms can develop on surfaces of prosthesis. The purpose of this study was to investigate the distribution of oral Candida species between the type of prosthesis and the situation of oral environment in patient with prosthetic appliance. The patients were 30 elderly subjects with different types of prosthesis, 7 who wore denture, 12 who wore implant and 15 who wore removable orthodontic appliance. We used Candida albicans colony forming unit test using saliva to exam the distribution of Candida albicans related with 5 oral environmental factors, gender, smoking or nonsmoking, alcohol/nonalcohol consumption, the type of prosthetic appliance and its treatment duration as well as tooth brushing frequency per day. In conclusion, for the patient's gender, site in the oral cavity and the type of prosthetic appliance and its treatment duration was associated with an increase in the distribution of Candida albicans in saliva. The distribution of Candida albicans within the oral cavity performs to be modulated to varying extents by oral environmental factors and, further investigations are required to elucidate these complex interactions.
Background: Surgical correction of the full spectrum of esophageal atresia with tracheoesophageal fistula has improved over the years, but the mortality and morbidity assoiated with repair of these anomalies still remains high. Material and Method: We retrospectively analyzes 27 surgically treated patients with esophageal atresia and tracheoesophageal fistula at Dong-A University Hospital between January 1992 and March 1997. Result: There were 21 male and 6 female patients. Mean birth weight was 2.62$\pm$.385 kg(2.0~3.4 kg). Twenty- four(88.9%) had esophageal atresia with distal tracheoesophageal fistula, and 3(11.1%) had pure esophageal atresia. Four(14.8%) infants were allocated to Waterston risk group A, 18(66.7%) to group B, and 5(18.5%) to group C. In eighteen(66.7%) infants with associated anomalies, cardiovascular anomalies were the most common. Three had a gap length of 3.5 cm or greater(ultra-long gap) between esophageal segments, 7 had 2.0 to 3.5 cm(long gap), 8 had 1.0 to 2.0 cm(medium gap), and 9 had 1 cm or less(short gap) gap length. Among 27 neonates, 3 cases underwent staged operation, late colon interposition was done in 2, and all other 24 cases underwent primary esophageal anastomosis. Oerative mortality was 2/27(7.4%). Causes of death included acute renal failure(n=1), empyema from anastomotic leak(n=1), necrotizing enterocolitis(n=1), sepsis(n=1), insulin-dependent diabetus mellitus(n=1 . There were 4 anastomosis- related complications including stricture in 3, leakage in 1. Mortality was related to the gap length(p<.05). Conclusion: Although the complication rate associated with surgical repair of these anomalies is high, this does not always implicate the operative mortality. The overall survival can be improved by effective treatment for combined anomalies and intensive postoperatve care.
