This paper deal with technique of tension length calculation for 350km/h high speed catenary system. Tension length affects in facility investment. Possibility of overlap increasing a tension length and the equipment investor decreases in order to decrease. Considers the parameter which specifies and the grudge which is possible long the fact that decides a tension length is the aim which is important plans overhead contact line. The element which decides a tension length with next following; (i) Operating range of tension device, (ii) Change of the horizontal tension which affects possibility of the effect which operates to the line and span, (iii) Tension of wire material the tensile force which is relation, (iv) Wire thermal expantion which relates with a standard temperature, (v) Curve radius, (vi) Wind velocity, (vii) Thermal range of overhead contact wire and mechanical design of tension mechanism etc.

The purpose of this study is to present that the strategic orientation affects on the green management performance. In order to carry out this research, the samples are reviewed and the ten hypotheses are verified reliably and appropriately. The results of the verification are summarized as follows: First, strategic directivity affects on the green management performance significantly. Second, two factors of the strategic directivity, customer orientation and technology orientation affect on the green performance relatively high. Finally, the two elements of the strategic orientation, competitive orientation and technology orientation affect on the financial performance significantly. In conclusion, this study shows all of the factors of the strategic orientation affect on the green management. In order to get the effective green management, education programs should be conducted by social support systems.

The purpose of this study is to suggest the implications of social welfare workers' understanding of emotional labor and prevention of psychological exhaustion. In order to achieve this goal, I analyzed the effects of the levels of surface acting and deep acting, which are components of emotional labor in social welfare workers in social welfare center, on emotional exhaustion, depersonalization, and lack of sense of personal accomplishment which are components of psychological exhaustion. And I empirically analyzed how emotional labor affects psychological exhaustion, when superior support and fellow support as components of social support play a role as moderating variables. Empirical results show that emotional labor affects psychological exhaustion and social support plays a moderating role. Based on these results, theoretical and policy implications and future research directions are presented.

In recent, the requirement of remote control of hychaulic system is in- creasing. The actuator unit whose output position is proportional to input electrical signal needs a pressure reducer and a dump valve. The pressure reducer provides a constant regulated pressure and filters contaminants. The dump valve supplies proper pressure to the pressure reducer and unloads when the system is not operated. In this thesis, dump valve and pressure reducer with auxiliary function are studied. The choke in the pressure reducer prevents actuator from supplying higher pressure than necessary pressure at beginning, and the spring constant affects on the dynamic characterisics. In dump valve, it is proved that diameter of servo-slide hold and choke diameter of dump plunger affects on damping response.

The purpose of this study is to analyze how future images are embodied in contemporary fashion design. To find out future images expressed in contemporary fashion design, this paper characterized the future society as information society, network society, pluralistic society, and global village. Cyber design and techno-style expressed through metal or lustrous material which is influenced by information symbolize future image. Also, minimalism which is characterized as simplicity and purity affects the contemporary fashion design. The network society which affets t the horizontal and functional social system diminishes the meaning of socio-economic status. Therefore, street fashion has diffused to high fashion, and the formal wear has tendency to be changed into casual wear. In addition, the meaning of status symbol in contemporary fashion design become decreased. The pluralistic society affects to search for one's own personality and identity. Also, contemporary fashion design is influenced by post-modernism and deconstructionism. In order words, genderless, ageles, seasonless, and infra fashion appeared. The global village emphasizes extension of universality in life style and search for world quality. so, ethnic fashions appear frequently in contemporary fashion design. Also, the effects of Korean traditional costume to contemporary fashion design has increased.

According to recent statistics, the number of family-owned small business have increased. And these growing numbers have created an urgent need for researchers and government to analyse and plan for this population. The purposes of this study were to identify the determining factors of the location of family owned small business and to analyze the factors related to their job satisfaction, and life satisfaction. The data used for this study, were 713 self-employed men and women which were elected from the panel data of 1998 MIPS of Daewoo Economic Research Institute. Statistics performed for the analysis were frequencies, percentiles, t-test, $\varkappa$$^2$, OLS and Logistic analysis. It was found that the person who work at home-base small office were the residents of smaller city, and are older than the office-going attendants. The variable which effects the job satisfaction of the home-based workers was the educational background. And sex was the only factor which affects the job satisfaction of the office-going attendants. It was also found that job satisfaction affects the life satisfaction significantly in both group.

The dynamics of the virus-host interface in the response to respiratory virus infection is not well-understood; however, it is at this juncture that host immunity to infection evolves. Respiratory viruses have been shown to modulate the host response to gain a replication advantage through a variety of mechanisms. Viruses are parasites and must co-opt host genes for replication, and must interface with host cellular machinery to achieve an optimal balance between viral and cellular gene expression. Host cells have numerous strategies to resist infection, replication and virus spread, and only recently are we beginning to understand the network and pathways affected. The following is a short review article covering some of the studies associated with the Tripp laboratory that have addressed how respiratory syncytial virus (RSV) operates at the virus-host interface to affects immune outcome and disease pathogenesis.

The purpose of this research is to find the relational influences of maternal child rearing behavior and peer acceptance on children's self esteem. The sample subject were 200 of fourth/sixth grade of elementary school. The major findings of the research were as follows : First, the scores of peer acceptance, social acceptance, behavior conduct, global self-worth and affect tend to be over the mean scores. Second, the influences of maternal child rearing behaviors and peer acceptance on children's self esteem found significant due to the sub-areas of self-esteem. The affectionate child rearing affects all sub-areas of self-esteem. Overprotection and peer acceptance affect social acceptance. In addition, gender affect cognitive ability and fade affects global self-worth.

Injection-stretch blowing system for preform has been developed in this study. The preforms for injection blow molding and injection stretch blow molding are being manufactured by injection molding. However it contains gate mark that affects the bottom crack in the PET bottle. The compression molded preform does not contain gate mark, thus the appearance quality of bottle has been increased and the residual stress near gate(bottom of the bottle) has been reduced. The thickness distributions, haze, and transmittance are well accepted for the preform. Also, flow characteristics of the resin between a core and cavity could be analyzed through computer simulation.
