The purpose of this study is to analyze the relationship between life style and health status of the staffs of an elementary school to understand exercise practices and life styles and to analyze the self-efficacy and the factors that affect it concerning walking exercise. The subjects were m9 staff member of the 10 elementary school in Seoul and materials were collected through an organized examination table from October, 1999 to May 2000. The people health awareness table was used as a variable for life style, the 13 questionnaires made of a 5 points measure was for the self efficacy concerning walking exercise. The data was analyzed through a statistics package made of a Chisquare-test, t-test, ANOVA and a regression analysis. The major results of this study were as follows; 1) 50% of the staffs were practicing regular exercise, 3/4 of them practiced walking, jogging and mountain climbing that don't need equipment and exercise frequency was 1-2 times per week 64%. of the time and exercise span was under 30 minutes in 38%, the highest 2) The average of self-efficacy concerning walking exercise was 3.6 points but the answers "I can walk enough to be in a sweat", "I can walk according to my exercise plan" were relatively low. 3) The explanation degree of the Model was 14% in a regression analysis between self efficacy concerning walking exercise and as a dependent variable for a regular walking exercise plan, regular health examination, routine health status, and breakfast might serve as an explanation degree. According to the results of this study, the suggestions were as follows: 1) The chronic invalid was not enough in the change of life style after chronic disease, most of all, it need the awareness of change, of active health education and of public information for health promotion action practice through the prohibition of smoking, abstinence from drink, exercise and nutritional balance. 2) Concrete practice program enlargement is needed to enhance related walking exercise or of a type lecture meeting for subjects who have a positive attitude about walking exercise plans. 3) A program that can actively recommend a health promotion life style is needed when we make allowance for those who have an ordinarily healthy life style and show a high walking exercise self-efficacy.

In this study, we have analyzed the cost of korea high-speed rail project. The predicted cost in planning phase and adjustment data to 5th year are collected. Then, predicted cost is compared with adjustment in year/item/system base. We make a project history table for criteria to review project history and research ＆ development activity. We have developed CBS(cost breakdown structure) and allocated adjustment data to them. It is shown that cost prediction related to research St development activity in planning phase is relatively correct.

Objective : Only a few studies have investigated the life expectance and health related quality of life (HRQOL) about stroke patients. The purpose of this study is to analyze the life expectancy, preference based quality of life(QOL) and quality adjusted life years(QALYs) of stroke patients. Methods : We used data of 10,533 adults from 4th Korean national health and nutritional examination survey 2009 for evaluating HRQOL of stroke patients. We also analyzed the life expectancy for stroke patients using life table from national public health data. Finally we calculated the QALYs with and without stroke conditions and assumed the difference of QALYs. Results : The mean age of stroke patients was assumed to be 65. Lower income and less educated groups were prone to be exposed to the stroke conditions. Common comorbidities of stroke patients were ischemic heart attack, hypertension, diabetes and hyperlipidemia. The proportions of participants who reported problems in each of the five EQ-5D dimensions increased significantly at chronic stroke group. Participants with chronic stroke conditions had an almost 6-fold higher risk of impaired health utility(the lowest quartile of EQ-5D utility score) compared with non stroke participants, after adjustment of age, gender, income, education, comorbidity variables. The differences of life expectancy and QALYs between non-stroke and stroke group from the age of 65 till death were assumed to be 0.767 year and 3.103 QALYs. Conclusions : Although the authors analyzed the affecting factors of QOL and assumed the differences of life expectance and QALYs about stroke patients using domestic national data and statistic references, well designed cohort studies should be needed to prove the causal effects of affecting factors and to assume more correct QALY differences.

아카시아진딧물은 다양한 기주식물을 먹이로 하는 곤충으로 전 세계적으로 분포하고 있다. 본 연구는 아카시아진딧물 약충의 발육기간, 무시성충의 수명과 번식능력을 조사하기 위하여 10.0, 15.0, 20.0, 25.0, 30.0, $32.5^{\circ}C$ 정온조건에서 실험을 실시하였다. 조사된 모든 항온조건에서 아카시아진딧물은 성공적으로 성충으로 발육하였고 발육율은 온도가 상승할수록 증가하였다. 아카시아진딧물 약충시기별 발육영점온도와 유효적산일은 선형회귀분석 방법을 이용하여 계산하였다. SSI모델을 이용하여 발육최저, 최고한계를 추정하였다. 아카시아진딧물 전체약충기간의 발육영점온도와 유효적산일은 각각 $5.3^{\circ}C$과 128.4DD였다. SSI모델을 이용한 아카시아진딧물의 발육최저, 최고온도는 $17.0^{\circ}C$과 $34.6^{\circ}C$였으며 이들간의 차이는 $17.5^{\circ}C$였다. 전체약충기간의 발육완료분포모형은 3-매개변수 Weibull함수를 이용하여 나타내었다. 온도와 관련된 아카시아진딧물의 생물적 특성을 생명표분석을 통해 나타내었다. 내적자연증가율은 $25^{\circ}C$에서, 개체군순증가율은 $20^{\circ}C$에서 가장 높았다. 다른 지역에 서식하는 아카시아진딧물의 생물적 특성을 비교 분석하였다.

Vitamin D contents in agricultural products and foods were quantified by high performance liquid chromomatography (HPLC) with a UV/Vis detector, using external standard methods. The results were confirmed with liquid chromatography tandem mass spectrometry (LC-MS/MS). After homogenization, samples were hydrolyzed by direct alkali saponification. Thereafter, fat-soluble components were extracted with n-hexane containing 0.01% butylated hydroxytoluene (BHT). Vitamin D contents in cereals were found to be in the range of $1.882{\sim}4.856{\mu}g/100g$. Juda's ear and oak mushroom contained high amounts of vitamin D, at 363.85 and $199.42{\mu}g/100g$ of edible portion, respectively.

High Speed Machining(HSM) reduces machining time and improves surface accuracy because of the high cutting speed and feedrate. Development of HSM makes it allowable to machine difficult-to-cut material and use small-size-endmill. It is however limited to cutting condition and tool material. In the machining operation, it is important to check main parameter of tool life and select optimal cutting condition because tool breakage can interrupt progression of operation. In this study, cutting parameters are determined to 3 factors and 3 levels which are a spindle speed, a feedrate and a width of cut. Experiment is designed to orthogonal array table for L9 with 3 outer array using Taguchi method. Also, it is proposed to inspect significance of the optimal factors and levels by ANOVA using average of SN ratio for tool life. Finally, estimated value of SN ratio in the optimal cutting condition is compared with measured one in the floor shop and reduction of loss is predicted.

A study of the factors influencing the quality of life and social support of people suffering with mental disabilities, who use mental health centers. The purpose of the study includes the general characteristics of subjects, characteristics of the mental health center, the mean score of social support and quality of life of people living with mental disabilities. The 132 questionnaires were administered by meeting directly with subjects and personal visits. 112 Questionnaires were returned(85% response rate). Data was collected from mentally disabled patients in Chungnam Mental Health Center. difference in quality of life by using t-test, one way ANOVA table, the relationship between social support, quality of life by pearson correlation coefficients, and relevant factors affecting quality of life by multiple regression with the SPSS 19.0 program. This study revealed that the group that participated regularly in the day time rehabilitation program showed better social support and positive attitude to a better quality of life than the other group that participated irregularly. This result is directly proportional to the participation frequency to the program during the recent 3-month duration. Another correlation with religion was found in the study due to the fact that a buddhist group showed positive significance in quality of life than non-religious groups. The results show positive correlation between the improvement of the quality of life of patients living with mental disabilities and the social support they receive.
