This study was undertaken to improve the perceived value of halophytes and contribute to the activity of the local economy by analyzing the antioxidant activity and mineral content of Suaeda japonica, Tetragonia tetragonoides, and Spergularia marina that grow wild on the mud flats and coastal areas. The total phenolic compound content found in each order is as follows: Suaeda japonica (3.674∼5.989 mg TAE/g dry wt.), Tetragonia tetragonoides (2.515∼4.471 mg TAE/g dry wt.), and Spergularia marina (2.450∼4.067 mg TAE/g dry wt.); DPPH radical scavenging and ABTS cation radical scavenging activities were also recorded in the same order. In the case of minerals, Iron(Fe) was relatively high in Suaeda japonica (960.1∼1,346.7 mg/kg), Manganese(Mn) in Tetragonia tetragonoides (197.1∼574.8 mg/kg), and Zinc(Zn) was relatively high in Spergularia marina (63.19∼216.56 mg/kg). It was confirmed that the mineral content of Suaeda japonica, Tetragonia tetragonoides, and Spergularia marina was significantly higher than that of Chinese cabbage, lettuce, leek, and spinach.

This study analysed the mercury concentration in the hair of 62 students (male : 21, female : 41) of D university in Najusi, Jeon-Nam area. Also, questionnaire, which developed by NIES, were completed by the students. According to the questionnaire, most of the students had a higher intake of meat than that of fish. Also, among the students, there were many smokes and many had dental treatment with amalgam. Based on the gender, female showed 1.024 ${\mu}g/g$ and male showed 0.882 ${\mu}g/g$ of the mercury concentration. This means that female students had higher level of mercury in their hair, but it was not a significant statistic difference. Comparing by the intake frequency of meat, processed food stuffs, protein foods, it shows the more they at the higher mercury concentration was observed. According to the intake frequency of fish, when the number of times they intake increased, the mercury concentration was higher. Under one time was 0.857 ${\mu}g/g$ and twice or more times were 1.152 ${\mu}g/g$, which showed a significant statistical difference (p<0.05). Depending on the Life style, the mercury concentration in the hair was high with workout, outdoor activities, and direct smoking. The mercury concentration in the hair showed no difference for whether they received amalgam treatment but the personal dietary habit and the Living condition affects strongly on the mercury concentration level.

Obesity is defined as an excess of body fat and is closely related to diabetes, hypertension and heart disease. Dietary cure has been paid attention as a method for preventing from or curing obesity. The effect of some food products developed in this laboratory, such as, functional saengsik (Health & Joy saengsik), diet food (Health & Joy diet meal) and intestine function activator (Cell-pa, commercial name) on curing and protecting from obesity were investigated. Diet program was applied to 31 adults (Males 22, Females 9) with above 120% body mass index (BMI). After diet program was applied, body weight, body fat and fat weight decreased by 1, 4.8 and 4.5% (p<0.01), HDL-cholesterol increased by 3.6% and LDL-cholesterol and atherogenic index decreased by 6.6 and 7.7% (p<0.05). Consequently, the food products developed in this laboratory effectively reduced the obesity.

A study on the spalling causes of work roll for cold rolling was performed in the cold rolling mill. Performance of work roll is dependent to a great extent on spalling so that both roll manufacturers and users show great interest in spalling. So this paper shows that spalling phenomena were investigated and causes determined because of more than 85% of spalling has its origin on the roll surface. As being well known, spalling mostly occurred due to developing fatigue fracture originated a crack on a roll. But such spalling can be prevented by proper roll maintenance. The spalling accidents have sharply decreased since 1981 because of the use of ultrasonic test to detect cracks on a roll.

Adipokines has been used to describe the numerous adipocyte secretory products, which include Tumor Necrosis Factor(TNF)-α, Interleukin-6(IL-6), Leptin, Resistin, and Adiponectin. There is growing evidence that adipocyte scretory products are important determinants of insulin resistance, cardiovascular, through either circulating hormonal effect or local effects on the adipocyte. The expression of adiponectin is low in rodent models or humans obesity of insulin resistance, cardiovascular and is accompanied by low muscle and liver lipid accumulation. adiponectin knockout mice develop severe insulin resistance in response to a high-fat diet, in association with higher levels of TNF-α and increased tissue lipid accumulation. TNF-α is considered as an important mediator of insulin resistance. However, the effect of TNF-α in skeletal muscle is still controversial. It has been shown, on one hand, that muscle TNF-α may play an important role in the development of insulin resistance in rat and humans. on the other hand it has also been reported that TNF-α may up-regulate glucose uptake in human muscle cells. Physical exercise is a well established method for the treatment of insulin resistance and type 2 diabetes mellitus and atherosclerosis. Adiponectin and TNF-α is associated with insulin resistance, cardiovascular and because it is know to respond to exercise

High level of reliability in facility operation is specifically required these days. The goal of this study is to secure a methodology for reliability analysis of hydro-power plant so that an appropriate decision for operation and investment can be made. Fault tree analysis of water supply system within hydro-power plant has been performed in this study. We briefly examined the electric power generation facility and water supply system. We then developed fault tree for the water supply system based on failure modes and effects analysis. We conclude this study and provided future research areas.

Austenite stainless steel 년 316 has heat treated to austenite structure by heating at 1100℃ for 1hr and suddenly cooling. These specimens has been dealed with aging treatment at 700℃ for 0hr, 2hr, 10hr, and 100hr separately, and then conducted by creep test on the uniaxial state of stress in atmosphere of 600℃. The experimental results are obtained as follows. 1) Creep rupture stain rate has increased by the increasing of aging time. 2) Creep rupture time have had large affect of aging time comparing with 0hr aging specimen and increased by 20%, 40%, and 60% separately for 2hr, 10hr, and 100hr aging specimen. The empirical formulas of creep rupture time "t" as follows. (aging time are in parenthesis) t?=2.297×10? t?=8.810×10? t?=2.951×10? t?=1.178×10? 3) Creep constant "n" has increased, "k" decreased and creep limit increased by increasing the aging time. Then creep strain rate has decreased and increased by increasing the aging time and stress. The empirical formulas as follows. ε?=3.326×10? ε?=1.905×10? ε?=1.347×10? ε?=3.465×10? 4) The creep strain rate multiplied by creep rupture time has constant value according to property of material and belongs to the range of parallel line at logarithmic graph paper. 5) Hardness has increased by the increasing of aging time and intergranular hardness is higher than transgranular hardness. 6) The micro cracks occur from wedge crack and cavitation crack at grain boundary and exist at the surface of specimen and the surface of longitudnal section. 7) High stress and aging specimens have mostly wedge crack. Low stress and nonaging specimens have mostly cavitation crack. 8) Rupture surface of higher stress has shearing fracture of about 45° inclination, and has tendency of fracture by directing perpendicular to the axis for decreasing creep stress and also has same phenomenon for occurrence and propagation of crack.

In currency crisis(IMF relief loan), the construction industry has prepared a foundation for existence by taking such desperate countermeasure as reducing a lot of construction companies and readjusting the their structure. Even though a number of employee of construction industry came to a million in 1996, it reduced to 980 thousand in 1997 and 710 thousand in 1998. After 1998, there was the trend about reducing a number of employee every year. The final goals of this study have inquired into the current situation of manpower supply and demand per region, compared and analyzed the circumstance of manpower supply and demand, and utilized references in decision-making between construction companies and students.
