The purpose of this study was to evaluate the current dietary habits, health related behaviors, nutrition knowledge and body indices, and to investigate the changes in nutrition knowledge for designing and monitoring nutrition education program among preschool children. The subjects were 1,200 preschool children, aged $4{\sim}6$ years. A measurement of the height and weight was conducted. The general home environment, the dietary habit of children and nutrition knowledge were collected using a questionnaire that included information about family income, parent's education and occupations. Using the PIBW, 14.6% of the preschool children were under weight, 54.4% were normal, and 31.0% were overweight or obese. We regarded to food habit score, the highest score was in the regularity of breakfast, while the lowest score was in consumption of yellow-green vegetables such as spinach and carrots. Result in food behavior showed that 69.1% of preschool children had a unbalanced diet, and their favorite snack was fast food like pizza and hamburger then followed soft drink and fried foods (chicken of potato). After nutrition education, there was somewhat improvement in the nutrition knowledge score of preschool children from $7.7{\pm}1.7$ point to $8.9{\pm}1.5$ point. These results suggest that nutrition education help preschool children change their nutrition knowledge. Therefore, it would be needed that new appropriate nutrition education to improve dietary habits and health status.

Background : Small cell lung cancer represents approximately 20% of all carcinomas of the lung, and is recognized as having a poor long term outcome compared to non-small cell lung cancer. Therefore, this study investigated the prognostic factors in small cell lung cancer patients in order to improved the survival rate by using the proper therapeutic methods. Material and method : The clinical data from 394 patients who diagnosed with small cell lung cancer and treated from 1993 to 2001 at the Kosin University Gospel Hospital, were analyzed. Result : There were 314 male patients (79.7%), and 80 female patients (20.3%). The number of those with limited disease was 177 (44.9%), and the number of those with extensive disease was 217 (55.1%). Overall, 366 out of 394 enrolled patients had died. The median survival time was 215 days (95% CI : 192-237days). The disease stage, Karnofsky performance state, 5% body weight loss for the recent 3 months, chemotherapy regimens, and the additive chest radiotherapy were identified as being statistically significant factors for the survival time. The median survival times of the supportive care group, one anticancer therapy, and two or more treatment groups were 17 days, 211 days, and 419 day, respectively (p<0.001). These data emphasize the importance of anticancer treatment to improve survival time for patients. The group of concurrent chemoradiotherapy (30 patients) showed significantly longer survival time than the group given sequential chemoradiotherapy (55 patients) (528 days versus 373 days, p=0.0237). The favorable prognostic factors of laboratory study were groups of leukocyte =8,000/mm3, ALP=200 U/L, LDH=450 IU/L, NSE=15 ng/mL, s-GOT=40 IU/L. In extensive disease, there was no difference according to the number of metastatic site. However, the median survival time of patients with ipsilateral pleural effusion had longer than patients having other metastatic sites. According to the survey periods, three groups were divided into 1993-1995, 1996-1998, and 1999-2001. The median survival time was significantly prolonged after 1999 in comparison to previous groups (177 days, 194 days, 289 days, p=0.001, 0.002, respectively). Conclusion: Disease stage and 5% body weight loss for recent 3 months at diagnostic state were significant prognostic factors. In addition, the performance status, serum ALP, LDH, NSE, CEA levels also appear to be prognostic factors. The survival time of those patients with small cell lung cancer has been prologned in recent years. It was suggested that the used of the EP (etoposied and cisplatin) chemotherapy method and concurrent chemoradiotherapy for patients with a limited stage contributed to the improved survival time.

This study was performed to investigate relationships among night eating and nutrient intakes status in university students. A total of 271 subjects (male=155, female=116) were divided by using 3-days food record method according to the percentage of energy from night eating: non-night eating, <25% night-eating and ${\geq}25$ night-eating group. There were no significant differences in age, height, weight, percent body fat and BMI among the groups. The proportion of morning anorexia and insomnia was below 2% and 10%, and no differences were observed among the groups by percentage of energy from night eating. In the male subjects, the intakes of energy in the '${\geq}25$ night-eating group' was significantly higher than those of the other groups; whereas, the nutrient density (ND, nutrient intakes per 1,000 kcal) and INQ (index of nutritional quality) of vitamin $B_1$, vitamin $B_2$, vitamin C, calcium and iron in the '${\geq}25$ night-eating group' was significantly lower than those of the other groups. In the female subjects, the intakes of energy in the '<25 night-eating group' was significantly higher than that of the 'non-night eating group'. And the ND and INQ of vitamin C in the '<25 night-eating group' was significantly higher than those of the 'non-night eating group'. In addition, within the male subjects, the INQ of vitamin $B_1$, vitamin $B_2$, vitamin C, calcium and phosphorous showed significantly negative correlations with food intakes, energy intakes and percentages of energy from night eating after the values were adjusted for age. These results suggest that among male university students, night snack intakes above 25% of energy have lower micronutrient qualities of vitamin $B_1$, vitamin $B_2$, vitamin C and calcium.

To investigate the effect of dietary supplementation of Acanthopanax senticosus (AS) and Eucommia ulmoides (EU) on antioxidant defense system in laying hens, a total of three hundreds sixty 20-wk old Hyline brown commercial laying hens were assigned to five dietary groups for 10-wk: (1) control diet, (2) control diet supplemented with AS at 0.5%, (3) control diet supplemented with AS at 1.0%, (4) control diet supplemented with EU at 0.5% and (5) control diet supplemented with EU at 1.0%. Total antioxidant status (TAS) in blood and antioxidant enzymes including superoxide dismutase (SOD), gluthathione -S- transferase (GST) and glutathione peroxidase (GSH-Px), and lipid peroxidation in the small intestine and liver were measured. There were no changes in body weight for 10-wk dietary treatment. TAS in blood significantly (P<0.05) increased in birds fed the diet supplemented with 1% AS and 0.5 and 1.0% EU compared with those fed control diet. Especially, dietary EU showed much higher (P<0.05) TAS compared with AS. In the antioxidant defense enzymes, GST activity of the small intestine was shown to be significantly (P<0.05) increased in birds fed the diets supplemented with 0.5 and 1.0% EU compared with those fed the control diet. In addition, intestinal SOD activity significantly (P<0.05) increased in birds fed the diets supplemented with 0.5% of AS and EU. However, we could not observe any significant dietary treatment effect of those antioxidant parameters in the liver. In conclusion, dietary supplementation of 0.5% AS and EU in a laying hen diet could be applied as a potential antioxidant source to improves bio-activity of antioxidant and economical aspect in laying hens.

This study was conducted to determine the effects of exogenous zinc-metallothionein (Zn-MT) on anti-oxidative function and pork quality. After feeding a corn-soybean meal-based diet for two weeks, 48 pigs ($Duroc{\times}Landrace{\times}Chinese\;Black Pig$) were assigned randomly to four groups. Pigs in Group 1 were maintained under non-stress conditions, whereas pigs in Groups 2, 3 and 4 were aggressively handled for 25 min to produce stress. Pigs in Groups 1, 2, 3, and 4 received intramuscular administration of saline (control group; CON), 0 (negative control group; NCON), 0.8 (low dose group; LOW), and 1.6 (high dose group; HIGH) mg rabbit liver Zn-MT per kg body weight, respectively. Pigs were slaughtered at 3 and 6 h post-injection. Zn-MT treatment increased (p<0.05) the activities of superoxide dismutase (SOD) and glutathione-peroxidase (GSH-PX) while decreasing the concentration of malondialdehyde (MDA) in liver. These responses were greater (p<0.05) at 6 h than at 3 h post Zn-MT injection. Zn-MT treatment increased (p<0.05) hepatic SOD mRNA levels in a time and dose-dependent manner and decreased (p<0.05) serum glutamate-pyruvate transaminase and lactate dehydrogenase activities (indicators of tissue integrity). Zn-MT administration decreased (p<0.05) lactate concentration and increased (p<0.05) pH and water-holding capacity in the longissimus thorasis meat. Collectively, our results indicate that intramuscular administration of Zn-MT to pre-slaughter stressed pigs improved tissue anti-oxidative ability and meat quality.

Background: Total anomalous pulmonary venous connection (TAPVC) is still one of the more challenging congenital heart defects in newborns and young infants. The purpose of the study is to evaluate the early and midterm results of the surgical corrections for patients in early infancy with isolated TAPVC. Material and Method: Hospital records of 15 consecutive patients in early infancy (January 1993 to August 1998) were retrospectively reviewed. There were 8 boys and 7 girls whose ages ranged from 4 days to 3.5 months (median age 22 days). Their body weight ranged from 1.75 kg to 4.9 kg (mean 3.54 kg). The abnormal anatomical connections were supracardiac in 11, cardiac in 3, and infracardiac in 1. In 6 patients (40%), the pulmonary venous drainage was obstructive. Total circulatory arrest was used in 13 patients. Anastomosis between the common pulmonary vein and the left atrium was performed with a continuous suture technique using a fine nonabsorbable polypropylene suture through a lateral approach behind the right atrium. Result: There was one hospital death (6.5%) caused by a sepsis 17 days after the operation in a neonate who had supracardiac drainage and was dependent on a ventilator preoperatively. There were 2 late deaths. One died sudde`nly of an unknown cause at home 2.5 years after the operation and the other died of a recurrent pulmonary hypertension 3 months after the reoperation due to pulmonary venous obstruction (PVO). Two patients required reoperations because of PVO 5 months and 10 months respectively after the initial operation. Of these patients, one patient is alive at the present time with persistent pulmonary hypertension. All survivors without postoperative PVO (78.6%) were in NYHA functional class I at mean follow-up of 25.8 months (0.5∼67 months). Conclusion: Surgical correction of TAPVC in early infancy can be performed at low risk. However, there were 2 postoperative PVOs (14.3%) which had bad results. The survivors without postoperative PVO had excellent functional status.

Purpose: The aim of this study was to evaluate the preoperative and postoperative nutritional statuses of patients with gastric cancer and to investigate the nutritional factors that are correlated with perioperative complications. Materials and Methods: From January 2008 to Jun 2008, 669 patients who underwent curative gastrectomy were enrolled in a retrospective study. To evaluate the changes of their nutritional status preoperatively and postoperatively, we measured the total lymphocyte count, the serum albumin, the body weight change and the BMI. The nutritional factors correlated with short-term postoperative complications were analyzed. Results: The total lymphocyte count and serum albumin decreased from the first preoperative day to the $5^{th}$ day after operation, but they tended to increase and approach the normal range 6 months after operation. The only factor correlated with the short-term postoperative complications (defined as the ones that occurred for 30 days) was the serum albumin checked on the $5^{th}$ day after operation. Conclusion: Low serum albumin on the $5^{th}$ day after operation was correlated with postoperative short-term complications. Serum albumin can be the preoperative statistical parameter that can predict the occurrence of postoperative complications.

Background : To evaluate the clinical characteristics of lung cancer patients in Korea, where there is a higher number of smokers than in Western countries. Methods : A retrospective study was performed on 1655 lung cancer patients, who were diagnosed at a university hospital between September 1996 and August 2005. Age, gender, cell types and clinical stage were analysed. Of 941 patients, who responded to a questionnaire at the time of diagnosis, the smoking habits, occupational history, family history of lung cancer in the first-degree relatives, coexisting diseases (diabetes mellitus and cardiovascular disease), body weight loss, ECOG performance status and presenting symptoms, were examined prospectively. In addition, coexisting diseases including chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis and active pulmonary tuberculosis were evaluated. Results : Of the 1655 patients, the male to females ratio was 3.6. Squamous cell carcinoma was the most common cancer whereas adenocarcinoma was more common in lifetime nonsmokers or women. 19.9% of the patients were non smokers and 80.1% ever smokers. Since 2000, there was an increase in the incidence of adenocarcinoma with a corresponding decrease in the incidence of squamous cell carcinoma. 6.2% of patients were asymptomatic. A coincident diagnosis of chronic obstructive pulmonary disease, cardiovascular disease, diabetes mellitus, active pulmonary tuberculosis, and idiopathic pulmonary fibrosis was made in: 44.1%, 22.2%, 10.7%, 3.9%, and 1.6% of patients, respectively. A positive family history of lung cancer in the first-degree relatives was identified in 4.4% of patients. An occupational history relevant to lung cancer was identified in 12.2% of patients. Conclusion : There is a high proportion of cigarette smokers in Korean lung cancer patients. The most common cell type was squamous cell carcinoma. However, a more detailed, prospective study of the clinical characteristics will be needed to better characterize lung cancer in Korea.

Authors studied the workers' knowledge about the health problems detected through the previous workers' periodic health examination, content of follow-up management ana actions taken for their health problem detected on previous health examination. From June to September 1992, workers' periodic health examination was peformed on workers employed in 10 companies located in 2 middle-sized Korean cities. A questionnaire survey was done far 150 workers who reported to have $D_2$ result of either hypertension or liver disorder at the previous workers' periodic health examination done in 1991. The results are as follows; 1. Of 160 workers who had $D_2$ result of either hypertension or liver disorder in previous examination one year before, only 85 workers(51.3%, 43 workers with hypertension, 38 workers with live disorder) responded that they have such disorders. The other 65 workers responded to questionnaire were all those with C results. Respondents' knowledge about their diagnoses was relatively precise (95.2% in hypertension group, 94.6% in liver disorder group) but knowledge about classification of diseases was poor. 2. The main efforts to solve the health problem nab self management (20 spells, 55.3%), visiting clinic or hospital(6 spells, 12.8%), use of herb medicine (2 spells, 4.3%) and use of drug store(2 spells, 4.3%) in hypertension group. In liver disorder group, 30 spells (71.4%) relied on self management,6 spells (14.3%) on hospital or clinic and 9 spells (21.4%) had no effort to improve the health problem. Content of self management was low salt diet, quit smoking, regular exercise and quit alcohol drinking in order. Avoidance of salt in diet was high in hypertension group and quitting alcohol drinking was high in liver disorder group. In those with self management, 80.7% of hypertension group and 83.3% of liver disorder group continued previous effort. Those, however, who utilized clinic or hospital, only 16.7% and 50.0% were still visiting hospital or clinic. 3. Fifty seven percent of hypertension group and 64.3% of liver disorder group was presently smoking,8.5% and 11.9% reduced smoking and 21.3% and 14.3% stopped smoking. Forty nine percent of hypertension group and 28.6% of liver disorder group was presently drinking. Reduced alcohol intake was reported in 29.8% and 40.5%, 12.8ole and 23.8% stopped alcohol drinking. Sixty six percent of hypertension group and 73.8% of liver disorder group did no regular exercise, but 12.8% and 11.9% of each group increased their physical exercise far last one year. Forty three percent of hypertension group and 38.l% of liver disorder group was overweight (defined by bodymass index greater or equal than 25). Reduced body Weight was reported in 17.2% and 16.7% of each group. Reduced dietary salt intake was high in hypertension group (51.5%). The study results suggest that follow-up management after workers' periodic health examination is not satisfactory. In order to improve this situation, adequate information on the result of the workers' periodic health examination should be distributed to each worker group with health education and counselling.

Purpose : Dialysis in children with chronic renal failure presents with many difficulies. The purpose of this study is to find an improved method in chronic dialysis in infants and children less than 2 years of age by analyzing the experience with 10 cases. Methods : A retrospective review of the medical records of 10 patients(6 boys and 4 girls) was conducted. The patients had chronic renal failure and underwent chronic dialysis at Samsung medical center from March 1999 to February 2007. Results : At Initiation of dialysis, the median age was 3 months old(22 days-20 months), the median body weight was 3.75 kg(2.2-10.3 kg), and the median serum creatinine level was 4.3 mg/dL(2.0-11.4 mg/dL). The median duration of dialysis was 29.5 months(3-62 months). Dysplastic kidney disease was the most common underlying renal disease. Two patients were treated with hemodialysis, 4 patients with peritoneal dialysis, and 4 patients eventually switched dialysis modality. Nine of the 10 patients took erythropoietin and anti-hypertensive drugs. At the end of the follow up period, 1 patient received kidney transplantation, 2 patients died due to sepsis, and 5 patients were treated with peritoneal dialysis. Two patients were lost to follow up. The most common complication of dialysis was infection. Achieving vascular access and maintaining proper catheter function were the most important factors in treating patients with hemodialysis. The growth status of patients was aggravated after 6 month of dialysis but improved after 1 year of dialysis. Patients showed better growth on peritoneal dialysis than hemodialysis. Conclusion : Chronic dialysis can be performed successfully in infants and children under 2 years of age. Vascular access was the main limitation of hemodialysis, and infection was the common problem in both hemodialysis and peritoneal dialysis. To improve the patients survival rate and quality of life, major efforts should be directed toward the prevention of infection and preservation of catheter function.
