This paper studies the relationship between SCM(Supply Chain Management) metrics and corporate value (Tobin's Q) for manufacturing and wholesale/retail firms in Korea. Specifically, the multiple regression analysis is used to investigate the relationships 1) between inventory level, inventory turns, and days of inventory and Tobin's Q and 2) between cash-to-cash (C2C) cycle time including its components such as days of inventory, days sales outstanding, and days payable outstanding and Tobin's Q. The results indicate that there exist statistically significant negative relationships between inventory levels and days of inventory (DOI) and Tobin's Q. Also, we found that there exist commonly known negative correlations between days of raw materials inventory and days of work in process (WIP) inventory and Tobin's Q. For the C2C cycle time, we found that there -exists a statistically significant negative relationship between the C2C cycle time and Tobin's Q. Also, we found that there exist commonly known correlations between the two components of C2C cycle time and Tobin's Q such as the negative for DOI and days sales outstanding. This study clearly shows the negative relationship in general between inventory levels and corporate value and between C2C time and corporate value, and this kind of result has not been found by previous studies in Korea.

This study was performed to suggest the health management of farmers compared with different farming types, such as rice plant, livestock, horticulture, orchard and others, for the farmer's health enhancement. For this study, 720 subjects were selected in 8 provinces through cluster method, and relevent caculations for the analysis of the subjects were made SAS program, and tested significance with x$^2$ and F value, those probability levels were 0.1%, 1% and 5%. Among the subjects, aged 40's were 38%, females 66%, elementary graduates (32%), and think of living conditions were average (67%). In the self-consciousness test for health, there was no significant difference of farmers with farming types. In the aspect of agricultural work situation, they took holidays according to the weather conditions or no pressed work to be done. And They took a break “when they feel tired during work”. For the recovery of fatigue, sleeping was chosen as the most favorite (68%) followed bathing (17%). but exercise was the lowest (7%). In the case of working conditions, 74% of them replied they work under average condition, and only 9% of them thought they were under pleasant surroundings. And 37% of them have had healthy food, for health practice and restorative for health. 20% of them have had breakfast irregularly. In addition to the regular meal intake, sufficient re자 and pleasant agricultural working conditions would be necessary for health, and the farmers themselves should recognize the importance and care of health. The project for enhancement of the farmers' health is needed and who should give guideline to have the responsibility for health.

As a disease that reduces quality of life, functional dyspepsia (FD) is associated with foods that may worsen its symptoms or cause it. The purpose of this study was to examine the nutritional status and dietary behaviors of FD patients. We investigated food intake, food intake frequency, and dietary habits of 45 FD subjects according to the Rome III Diagnosis Criteria. Average age and body mass index (BMI) were 47.7 years and $22.6kg/m^2$ (males: $23.4kg/m^2$, females: $22.1kg/m^2$), respectively. Average energy intake was 77% of Korean Dietary Reference Intake (KDRI), and it was less than that of the Korea National Health and Nutrition Examination Surveys (KNHANES). Other nutrient intake levels were similar to the KNHANES. Energy intake proportion of carbohydrates : protein : fat was 56 : 18 : 26, and the ratio of fat intake was higher than that of the KNHANES. Beans, laver, tomato, and yogurt were consumed very frequently. In the results of meal regularity, dietary behaviors and composition of diet were relatively good. It is likely that the patient controlled their diet by eating cautiously and by reducing alcohol drinking and smoking. Our results indicate that FD patients' nutritional status by consumption of nutrients was at a level of normal healthy people and that dietary habits were better than normal adults. However, their fat intake levels were somewhat higher than normal people. Therefore, further research is required to identify the relationship between dietary intakes and FD.

In order to elucidate the effects of a lacto-ovo vegetarian diet on serum lipid levels, 91 male collegians residing in the Seoul area were recruited. The vegetarians did not smoke tobacco nor drink alcohol. Their anthropometric measurements, dietary intakes, and blood lipid concentrations were compared to age-matched omnivorous controls. The subjects were divided into four groups. The four groups were: 1) NSNDV (n=25): Non Smoking Non Drinking Vegetarians, 2) NSNDO (n=10): Non Smoking Non Drinking Omnivores, 3) SDO (n=37): Smoking, Drinking Omnivores, 4) SDM (n=11): Smoking Drinking Meat-eaters. Total serum cholesterol, HDL-cholesterol and hematocrit were analyzed. The results were as follows: Weight (p<0.05) and BMI (p<0.01) were significantly higher in SDM than NSNDV. Dietary protein (p<0.01), iron (p<0.05) and dietary lipids (p<0.01) from animals in NSNDV were significantly lower than the results in the SDM. Interestingly enough, we noted no significant differences between the four groups in terms of average total dietary protein, dietary lipids and dietary iron, total serum cholesterol, or HDL-cholesterol. Dietary fiber intake was significantly higher in NSNDV than in SDM (p<0.05). Weight, BMI, and total cholesterol were significantly positively correlated with animal protein (p<0.05) and animal lipid (p<0.01) intake. These results showed that vegetarian collegians who haven't smoked tobacco nor drunk alcohol evidenced lower body weight, BMI, and dietary animal lipid intake, but higher dietary fiber intake, than the other three groups. Additionally, intake of animal protein (p<0.001) and intake of animal lipids (p<0.001) were significantly positively correlated with body weight, BMI, and total serum cholesterol in male collegians.

The purpose of this study was to analyze the quality characteristics of bread with added saltwort powder in the amounts of 0%, 3% 5% and 7% based on the wheat flour weight The results were as follows. The 7% group had the lowest water content and the highest content of ash and protein. There were no significant differences in fat content between any samples. There were also no significant differences in dough weight between samples, but after baking, the control showed the lowest weight. Baking loss increased with increasing amounts of saltwort powder. The bread volume was the highest with the control group, and its specific volume decreased as the ratio of saltwort increased. By the color difference meter, the L value became lower as the ratio of saltwort powder increased, and the saltwort powder groups had higher a and b values than the control group did. Hardness was at a minimum in the control group, and it increased with increasing amounts saltwort powder. There were no differences in springness between samples. Cohesiveness tended to decrease, and chewiness an brittleness increased. with increasing amounts of saltwort powder. In sensory tests, the 3% group showed the highest color, flavor, and taste. Aircell sizes were greatest with the control group. The higher the ratio of saltwort powder, the higher the aircell size became. Softness was the highest within the 3% group, as was the overall preference.

Purpose: The purpose of this study was to identify the relationships among distress from drinking, alcohol abstinence self-efficacy and outcome expectancy in youths. Method: The participants in this study were 174 university students who were enrolled by convenience sampling. The data were collected from March to August, 2005. Descriptive statistics and Pearson's correlation coefficients with SPSS 12.0 were used to analyze the data. Results: There were significant differences in the physical distress from drinking according to gender, age, residence, drinking frequency and drinking capacity. There were significant differences in alcohol abstinence self-efficacy by drinking frequency and drinking capacity. There were significant differences in drinking outcome expectancy according to gender, drinking frequency and drinking capacity. The physical distress from drinking showed a significant positive correlation with alcohol abstinence self-efficacy (r=.312, p=.000) and negative correlation with drinking outcome expectancy (r=-.353, p=.000). Alcohol abstinence self-efficacy showed a significant negative correlation with drinking outcome expectancy (r=-.387, p=.000). Conclusion: There were relationships among physical distress from drinking, alcohol abstinence self-efficacy, and drinking outcome expectancy. These findings provide the basis to prevent problems of drinking by developing alcohol control program for university students.

The pharmacological properties of ginseng are mainly attributed to ginsenosides, the active constituents that are found in the extracts of different species of ginseng. Lately; the studies on ginsenosides are mainly focused on IH-901, a major intestinal bacterial metabolite of ginsenosides. In this study; we examined the anti-diabetic activity of IH-901 in C57BU61 db/db mice model. IH-901 was administrated orally at a dose of 20 mg/kg for 5 weeks. During the experimental period, body weight and blood glucose levels were measured every week. After 5 weeks, db/db mice were sacrificed and diabetic parameters were analyzed. IH-901 treated group showed a significant decrease in fasting blood glucose levels (from 10.5 mM to 9.4 mM), insulin resistance index (from 163.6 to 100.2) and triglyceride levels (from 115.3 to 70.1) compared to the diabetic control. In Pancreatic islets morphology; IH-901 treated group revealed much less infltrated mononuclear cells, indicating that IH-901 recovered ${\beta}$-cell damage due to hyperglycemia. In addition, IH-901 upregulated expressions of glucose transporter 4 (GLUT4) and PPAR-${\gamma}$ in skeletal muscle and adipose tissue, respectively. Taken together IH-901might be a potential anti-hyperglycemic agent with insulin sensitizing effect.

This paper studied the stress of Metropolitan Transit driving crews. Stress to such workers can not only lead to fatalities and infrastructure damage but also enormous loss of competitiveness. The study was carried out to search for ways of alleviating stress of driving crews. In order to reduce the various factors that exacerbate job stress of driving crews of Metropolitan Transit, it is first necessary to expand training in order to enhance their expertise, and improve facilities to protect driving crews in the event of accidents. Second, psychological compensation or organization's systems may cause job stress. It may therefore be possible to solve fundamental problems through typical organization level approach such as leadership training programs. Third, job stress may be reduced through proper life habits such as personal regular exercise. Fourth, we need to improve driving crews' working conditions and adjust working hours by avoiding excessive performance competition and an unfair evaluation system, by understanding their mental states, and by setting up systems such as a comprehensive health improvement and management program at the organization level.
