The bioethics as a comprehensive and normative control method of life sciences including the technology of advanced medical care, on the one hand, it has modified the conditions for allowing the progress of life sciences. On the other hand, it has put the brakes on attempts of life sciences violating the dignity and value of human beings, natural order. Positively, bioethics presents ethical bases, suggests organization of the legal and institutional conditions, and enables elimination of the legal and institutional obstacles, for the progress of life sciences. Negatively, it has presented justifiable prospects and road maps of life sciences, not to take indiscreet and intemperate turn of violating the dignity and value of human beings, natural order, and its such roles must be carried on.

Today's environment of enterprise is changing. They have to face customer' demands with the right product, the right service and supply them at the right time. And also cut down logistics and inventory cost and bring up the profit as much as they can. This means the change of putting enterprise first in importance to putting customer first importance. therefore to correspond to customer's demand, shorting lead time is becoming a essential condition. The answer to this changes of environment is supply chain management. In this paper, It consolidates the necessity on a LTV(Life Time Value) and analyzes data which is concerned of Customer Value. Under the these environments, defines the LTV(Life Time Value) rule that can improve the customer value.

Leisure time is a critical part of modern life and is increasingly important in modern society. Therefore, analyzing expectations and values of leisure and researching leisure practices are integral in measuring the quality of life. In this respect, differences between values and attitudes leading to the ideal leisure life and the actual leisure life could provoke negative influence on our lives, further, decreasing quality of life. Therefore, classifying leisure lifestyle through analyzing value of lifestyle and the actual state of leisure precisely is very necessary. Leisure lifestyle could be very useful standard satisfying various desires and demands related to leisure. In the research, we surveyed 3,000 people over 10 years of age, one on one interview method, asking value of life behaviors (Individualism vs. Collectivism, Pro-Stability vs. Pro-Change, Statistical way of life vs. Active way of life, Family-centered life vs. Work-centered life) and practices of leisure life (With whom, How frequently, Where, For what) in respect to both value and behaviors. Through this survey, five groups of leisure life type have been identified; "Community-oriented Type", "Cocoon Type", "Family-oriented Type", "Personal-stability Type" and "Multiplicity Type". These leisure lifestyles would provide effectual alternatives for reducing gaps between expectations for ideal leisure life and actual life. Furthermore, this could be used for ground work to develop measurements for satisfying various leisure demands.

The tensile strength (TS) and elongation-at-break (EB) loss of a CR/CB rubber composite sample prepared for the automotive parts were measured after accelerated thermal ageing at temperatures of 100, 120, 140, and $150^{\circ}C$. The change in TS was observed to be linear from the master curve prepared using the time-temperature superposition-principle (TTSP). An Arrhenius type of shift factor, $a_T$ was used to predict the life time of the sample, and a plot of ln $a_T$ vs. 1/T was also shown to be linear. The activation energy ($E_a$) of the sample was calculated as 70.30 kJ/mole from the Arrhenius plot. The expected life time of the sample was predicted at the given operating conditions by applying Arrhenius analysis. Assuming the $E_a$ value was constant at lower operating condition, life time of the sample was calculated as 2.3 years when the life limit was set as time to reach the 20% decrease of the initial TS value at operating temperature of $40^{\circ}C$.

In this paper, breakdown strength and time to breakdown are experimented under semiconducting layer/needle electrode in XLPE which is used for power cable insulator. Shape and scale parameters of obtained data are estimated using 2-parameters Weibull distribution. Life-time coefficient(n-value) using shape parameters for breakdown strength and time to breakdown tests is estimated. n-value of 1000 hour aged XLPE showed higher value than that of virgin XLPE. Increase of n-value is estimated by the stability due to removal of by-product and residue gas in XLPE by heating.

The purpose of this research is to study the middle and high school student’s value on the family life of the contemporary society. The data for this study has been collected for 808 students of kangwon-do by Liert-scale Type questionnaire. The data were processed by SPSS-X Program. Frequency, Percentage, Mean, Standard Deviation, One-way ANOVA, Pearson’r coefficient, Step-wise multiple regression and Cronbach’coefficient have been calculated and analyzed. The Summary of this research is described as follows. Firstly, the overall average of value of family life was 3.25 points which reflected more or less modern tendency. Secondly, significant difference in the student’s value of family life affected by environmental variables were such as sex(P<.001) school years(P<.001) group(P<.01). Thirdly, the overall average of the student’s interest in the home economics was 3.74 points which reflected heigher tendency, Significant difference in the student’s interest in the home economics according to environmental variables were such as sex(P<.001) school years(P<.05), living standard(P<.01), residential area(P<.001). Fourthly, the student’s overall interest in the home economics and their view on the family life were correlated as follows; Spare time(r=-1.3), parents-children(r=.12) relatives and neighbors(r=0.8) show lower correlation and household work(r=.07) show higher correlation. Fifthly, the area which has closest correlation with the value on the family life was the value on family economics, whereas is has been shown that the field with least correlation was the area of supporting the spare time. Sixthly changes that affect the student’s value of the family life were such as sex (${\beta}$=.43), school years(${\beta}$=.18), group(${\beta}$=.15) and interest degrees(${\beta}$=-.12). These whole explanatory power was 21%.
