The purpose of this study is to investigate the preference of the hand and the sensibility image of underwear textiles according to seasons. According to a recent survey of 109 college students, using a 7 scale evaluation to the preference of the hand and the sensibility image among 13 summer and 10 winter underwear textiles. The data was analyzed through mean, SD, factor analysis, t-test, Person correlation analysis and regression analysis using SPSS Win 11.0. The summer underwear textiles were classified according to six tactile factors: stiffness/surface unevenness, weight, elasticity, moistness, extension, and warm-cool and 3 sensibility image factors: elegant individual, modern, and sporty-casual. The winter textiles were classified according to six tactile factors: stiffness/surface unevenness, elasticity, warm-cool, drapability, moistness and flexibility and divided into 2 sensibility images: modern elegant and sporty-casual. Factors expressing hand and sensibility image according to season showed significant difference. In the summer, weight, in the winter, drapability and flexibility showed significant difference at the hand factor evaluation. The hand factors: weight, warm-cool and modern sensibility image factors effect the preference of summer underwear textile, also the hand factors-elasticity, stiffness/surface unevenness and the sensibility image factor-easy-sport-casual-effect the preference of winter textiles. Therefore, the thin, light, and cool textiles which are also gorgeous and sporty-casual are preferred for summer underwear textiles while soft, simple and comfortable textiles are preferred for winter textiles.

Single-phase and three-phase load can be used together in 3-phase 4-wire system. Single-phase and three-phase loads can be classified as linear loads without harmonics and nonlinear with harmonics. Single-phase linear loads are linear loads such as lamps and heat, and single-phase nonlinear loads are power converters such as rectifiers. It is recommended that the distribution of loads in the 3-phase, 4-wire distribution lines be evenly distributed within a certain range. However, harmonic currents generated in a nonlinear load flow on the neutral line and affect the phase current magnitude. The difference in the magnitude of the individual phase current due to the influence of the harmonic current present in the neutral line can produce a difference in current and load unbalance. In this study, current unbalance ratio and load unbalance ratio which can occur when a combination of linear and nonlinear loads are applied to 3-phase 4-wire distribution line are calculated.

The research was carried out in order to assess, at an early stage, the potential barrier in mother-child relationship in the childs' development by using the screening tool. Consequently, after modifying the Neonatal Perception Inventory developed by Broussard and testing its reliability. It has been applied to 152 mothers at the hospital of three universities in Seoul from August 1 to September 30, 1986. The data was analyzed by S.P.S.S. pro-gram and the results were as follows: 1) Mothers perceived the newborn as an individual, and evaluated their baby higher than other babies. 2) Mothers indicated difficulties in their role performance in the fellowing order-bathing, safety, detecting pain or suffering, and feeding. 3) Mothers' perception of a newborn was positive for 75% of the mothers. 4) The factor analysis of the modified tool using principal components analysis and Varimax rotation resulted in the two factors: Factor 1, Baby as an individual: Factor Ⅱ, Performances are required to meet the new-born's needs. 5) The difference in mothers' individual characteristics such as the number of childbirth, the desire to get pregnant or not, the type of deli-very, and the sex of the newborn did not influence on a mothers' perception of her newborn. As seen above, most of the mothers perceived their newborns as able individuals and expressed difficulties involved in taking care of the newborn. Also most of the mothers perceived their babies positively. My point here is, we ought to observe those mothers who perceive their babies negatively, and then compare them with those mothers who perceive their babies extremely positive or extremely negative. In the future, for more comprehensive assessment tool for maternal perception of the newborn, a repetitive verification and modification of this tool is demanded. At the same time, father's perception of the newborn should be included.

Total particulate mater (TPM), $NO_2$ and $NH_3$ were measured simultaneously in the smoking and non-smoking locations during an eleven month period from March 1986 to January 1987 at three sites in Chicago : Illinois Institute of Technology Cafeteria, Rush-Presbyterian St. Lukes Medical Center Cafeteria and a downtown office building. From this study, the mean concentrations of $NO_2$ and $NH_3$ were not significantly different between the smoking and non-smoking locations at any sampling site ; however, there was a statistical difference for TPM between the smoking and non-smoking locations. Activity factor was useful for describing the contribution from indoor source. The linear regression analysis was reasonable method for discriminating the individual contribution of source to determine the emission factor. The TPM emission factor determined from this technique was in good agreement with value from the literature.

As government's policy is enacted to reduce greenhouse gas emission in transportation sector, railroad sector has to estimate amount of emission and propose feasible methods to reduce emission. To calculate accurate emission of railroad sector, we performed a study on the calculation model development for Tier 3 GHG emission factors. According to IPCC guide line, Tier 3 emission factor reflects individual characteristic of diesel locomotive. For this reason, we estimated GHG emission factor by stratified diesel locomotive and the result show difference of emission factor by notch changing. Therefore, the analysis of notch frequency during operation is required to develop Tier 3 emission factor, and we analysed a running pattern of diesel locomotive. As a result, idle and 8 notch consist about 70% of total running distance. In conclusion, the calculation model suppose that Tier 3 GHG emission factor is the sum of multiplied emission factor by weights in each notch. This result can contribute to Tier 3 emission factor calculation and reduction method development of emission in railroad sector by managing driving efficiency and technology development.

The purpose of this study was to investigate the variables that had an effect on the maturity of career attitude in middle school students. Independent variables were categorized into three groups: individual-related variables, family-related variables, and school-related variables. The individual-related variables were gender difference, academic year, academic achievement, and self-efficacy. The family-related variables were socio-economic status of the family, communication about career with parents, parental support, sibling's support, and value orientation of the family. The school-related variables included communication about career with friends, teacher's support, and friend's support. The subjects of this study were 490 students who were selected at random from first, second, and third grade of middle school in Daegu. A questionnaire was used for the survey. It consisted of a career attitude maturity scale, a self-efficacy scale, a communication scale, a value orientation of the family scale, and a social support scale. The data was analyzed by factor analysis, multiple regression analysis, and hierarchical regression analysis. The major findings of this study are summarized as follow: First, among the individual-related variables that had an effect on the maturity of career attitude in middle school students, self-efficacy affected all sub-factors of how mature they were in matters relating to career. Academic achievement affected decisiveness and preparation-- maturity of career attitude subfactors. And gender difference and academic year affected preparation and goal orientation. Second, the results of the family-related variables that had an effect on the maturity of career attitudes in middle school students were that communication about career with parents affected decisiveness, preparation, and confidence-- maturity of career attitude sub-factors, socio-economic status of the family and sibling's support affected confidence. And value orientation of the family affected goal orientation and independence. Third, the results of the school-related variables that had an effect on the maturity of career attitude in middle school students were that communication about career with friends affected preparation-- a maturity of career attitude sub-factor; teacher's support affected decisiveness, preparation, and confidence; and friend's support affected confidence and independence. Fourth, decisiveness, preparation, and confidence among the maturity of career attitude sub-factors were affected the most by individual variables. And self-efficacy was the most significant. Goal orientation and independence were affected the most by family-related variables.
