활선작업시 개폐섬락전압은 철탑형태와 작업유형에 따라 개폐섬락전압이 달리 나타나게 된다. 즉, 활선작업자의 위치, 철탑 종류 및 애자장치 종류 등에 따라 개폐섬락전압은 다르게 나타나기 때문에, 적용하고자 하는 활선공법이 있다면, 이에 대한 개폐섬락전압의 특성을 파악해 둘 필요가 있다. 점퍼V련은 일반적으로 선로의 수평각이 중각도 지역에 설치된다. 즉, 수평각이 너무 커서 조립식 점퍼장치를 설치할 수 없는 철탑에 점퍼V련 장치를 설치한다. 765kV 송전선로에서 실제 점퍼V련 장치가 많이 설치되어 있지 않으나, 이 경우에도 유지보수 사항이 발생할 수 있기 때문에 안전한 활선작업을 위한 실규모급 개폐섬락특성에 대해 검토할 필요가 있다.

금융가격별 지표의 변동성 증가에 대처하려는 보수적 투자가들이 이용할 수 있는 매력적 방안의 하나가 보험부 투자기법이다. 그러나 이 투자유형은 설계에 상당한 신축성을 보이며 이는 동시에 투자성과 구조의 신축성으로 반영된다. 주요한 설계차원의 하나가 위험투자의 손실발생시 보상차원이다. 여기에 일반적 보험개념을 적용할 때 투자가가 직면하는 선택문제의 하나는 부분보험계약형 투자설계시 공제부보험형 전략과 공동보험형 전략간의 선택이다. 일반적 보험 이론에서는 전자가 후자에 대해 우월한 유형이라는 것이 밝혀져 있다. 본 연구는 이를 보험부투자에 응용할 때도 양 전략간에 어떠한 우월관계가 존재하는 지 알아보려 시도했다. 이를 위해 효율성 평가기준의 하나인 간편한 확률적 지배기준을 적용하였으며 분석결과는 생산적이었다. 두 전략 각각의 기대수익률의 확률분포를 대상으로 기대수익률이 상대적으로 공제부보험형 전략에서 공동보험형 전략에서보다 상대적으로 높거나 최소한 같은 경우에 전자가 후자를 지배하며 그 반대조건인 경우에는 양 전략간에 우열관계가 나타나지 않는다는 결과를 얻었다.

In the existing research paper, we developed Mechanical Pressurizing Equipment(MPE) that can apply a certain amount of pressure and found out about improving the bonding strength of repair materials constructed in the repair section, and if pressurized, the bonding strength could be increased. In this study, the pressure of Mechanical Pressurizing Equipment(MPE) was changed to 0, 10, 30, 50, and 80 kPa, and the test was conducted to select effective pressure by measuring the flexural, compressive, and bonding strength of the specimens and deformation of the pressure plate at the age of 3 and 28th days. As a result of the test, 30 kPa was the most efficient pressure for the MPE. After producing the specimen with three types of repair materials with different main components, the bonding strength was measured according to dry and wet conditions, construction site (ceiling, wall and floor), and whether or not pressurized, on the 3rd, 7th, 14th, and 28th, indicating that the repair materials mixed with cellulose fiber was most effective for the MPE.

This study investigated subtypes of men who batter, and explored the differences among them. It was based on 217 subjects from all around the nation who received legal punishment. In the analysis of the typology, we specifically tested whether the Holtzworth-Munroe and Stuart proposed typology was verified. The results of the cluster analysis revealed support for their theoretical distinction for three types of abusers. These results imply that Holtzworth-Munroe and Stuart's batterer typology is applicable to Korean batterers to some degree. Type 1 men demonstrated the lowest levels of physical and psychological abuse toward their wives and were the least likely to have had a history of child abuse or alcohol problems. These men had lower MCMI scores and did not show any extraordinary personality traits. Men in this category were violent only against their wives, had relatively liberal sex role attitudes and had the most satisfaction in their intimate relationships. Type 2 men were violent only at home, using a moderate level of violence. These men had very high levels of dependency on others and showed a borderline, avoident or passive-aggressive personality. The amount of alcohol consumption was similar to Type 1, but scores of jealousy, self-esteem, and attitudinal variables were similar to Type 3 men. They lacked assertiveness skills and reported the least marital satisfaction. Type 3 men used the most severe violence and were violent both inside and outside the home. These men showed signs of antisocial and aggressive personality. They had experienced frequent physical abuse during childhood, were the most likely to abuse alcohol and had lower self-control. Type 3 were the most traditional in their views of women's roles and had attitudes supporting violence. Based upon the study findings, practical implications of enhancing treatment efficacy were considered.

This study aims to examine the opposant of conventional images of women against heroines in the genre of TV melodramas having been produced since 2005. To attain the goal, it investigates the alteration of female opposant types in 27 dramas with female opposant in them among the melodramas positioned high in terms of ratings from 1992 to 2011. As a result, first, after 2005, docile tendencies increased in female opposant. Second, pure and feminine appearance increased. Third, women with conservative sexual consciousness increased. Fourth, in relationships with others, they showed more dependent tendencies. Although female opposant in the past were characterized by strong character, unfeminine attitudes, or dressing up the outside, after 2005, female opposant tended to show characteristics more like heroines' in the past. This research result implies that after 2005, there has been alteration in the paradigm defining female image.

Currently, attentions toward the Chinese market have been growing rapidly. Economical values of China are highly appreciated. The current shift of economical environments in China leads to changes in the way of consumers' consumption. The purpose of this study is to identify the Chinese consumers' brand purchasing behavior according to their lifestyle. Questionnaires developed by researcher were distributed and collected from 118 Chinese consumers living in metropolitan areas of China. In research, five different lifestyles were identified; which are the vogue pursuing group, the social intercourse group, the traditional conservative group, the achievement pursuit group, and the passive stagnated group. These groups differed in the perception of cosmetic prices, purchase motivations, post-acquisitional satisfaction, and their demographics. For example, the vogue pursuing group consumers turned out to consider price as the most important element when they purchase cosmetics, while the social intercourse group valued recommendation from others more. Meanwhile the traditional conservative group and the achievement group each used past experience and attributes as their criterion.

A number of tangible cultural properties have been left to suffering damage without any scientific conservation or maintenance. We conducted nondestructive geophysical explorations around the Western pagoda of the Iksan Mireuksa Temple for the purpose of preparing the counterplan of its conservation and maintenance and of utilizing the geophysical information for the design of repair. Geophysical image of the shallow subsurface around the construct resulting from electric resistivity, seismic refraction, and GPR methods carried out along 6 lines in the site was used to investigate the relationship between the foundation characteristics and the structural safety. Tilting of the pagoda southwest towards seems to result from the low resistivity zones found in the southwestern part. The GPR and seismic surveys revealed a boundary at depth of 3.3～3.5m dividing into two layers, compacted overlaid soil and the original ground. The boundary appears to dip southwest. The artificial layer as a foundation does not covers as much as the bottom area of the pagoda. This top soil dipping southwest seems to result in tilting of foundation southwestward towards. Our geophysical result suggests ground reinforcement in the western part of the survey area for the conservation of the construct.

In recent years, the proportion of medium and small-sized apartments within the housing market has seen a noticeable increase, alongside a corresponding rise in disputes related to construction defects. Such disputes are most prevalent in the finishing works phase of construction, which not only are frequent in occurrence but also impose significant repair costs. Furthermore, there is a noticeable scarcity of research focused on the quality management of finishing work defects prior to the completion of construction. Addressing this issue necessitates a methodology capable of preemptively identifying defects by analyzing their frequency and associated costs across various defect types. Consequently, the aim of this study is to propose a risk assessment methodology by conducting an analysis of defect cases across 3,299 apartment units, considering aspects such as frequency and severity. The outcomes of this research endeavor are expected to offer practical management strategies to enhance the quality of apartment finishing works and serve as an academic foundation for the enhancement of construction management systems pertaining to apartment finishing works.

The purpose of this study is analyzing newly the role of the educare teachers by finding the teachers' subjective perception on their duty and understanding its feature. With the research, I'd like to present the fundamental materials for re-training and education for specialty. I Q-sorted 17 teachers based on the 36 statements which had been selected carefully. The results are following. The first type is the teacher who is aiming the specialized education. The teacher of this type needs to have the comprehensible knowledge on the child-development and seeks the teacher's specialty with self-supervision and study group. The second type is the teacher who is pursuing safety and protection for the children. The teacher of this type considers safety and cleanness very important and thinks that he or she should take care of the children by the cooperation with parents. The third type is the teacher who is heading for everyday's life and improvement. He or she thinks that teaching the child daily life is significant and by it, the child should grow up. The results of the research show us 3 points. The first, we need to re-design training program for the educare teachers. The second, we should prepare the manual for the teachers in accordance with the infants' growing-up. The third, we should understand the teacher's type and train him or her in accordance with the type.

Component-based development(CBD) has been generalized in industry to master the complexity and reduce the development cost and time. However, current CBD practice is developing the component which is dependent on single application[l][2]. Therefore component variability is emphasized to reuse the component in many family members in a domain[8]. However, components are developed for the reason of replaceability rather than the reusability which is the main purpose of the component due to the insufficiency of the study of component variability definition and type[3]. In this paper, we formally specify the component variability reflecting the characteristics of the component to increase the component reusability. We define the logic variability which was recognized as the existing component variability and we propose all types of variability existing in the component by suggesting three more variability types. And we propose the component variability scope which makes us estimate and verify the number of cases of the variability when we customize the component. We propose these component variability types and scope through formal specification. By applying these techniques in developing components, we can develop high quality components reusable in many family members.
