전기식 출입문 시스템은 철도차량 영업운전에 영향을 주는 가장 중요한 시스템 중의 하나이다. 도시철도차량의 출입문은 승객들의 승하차를 담당하는 장치로써 고장이 발생할 경우 승객의 안전과 직접적인 영향을 미치기 때문에 열차운행에 영향을 미치는 중요한 장치이다. 최근에는 전기식 출입문 시스템의 신뢰도 목표값을 철도운영자가 철도차량 설계와 제작을 위한 발주사양 기술 요구조건에 포함하는 경향이 있으며, 차량 제작자는 제작시 발주사양기술 요구조건에서 철도운영자가 제시한 전기식 출입문 시스템의 신뢰도 목표값을 만족시켜야 하고, 철도운영자는 유지보수 데이터를 기반으로 공급자의 신뢰도 목표값 달성여부를 확인하고 승인하여야 한다. 본 연구에서는 전기식 출입문 시스템의 유지보수 현장 데이터를 수집하여 신뢰도를 미니탭 통계프로그램으로 분석하였다. 현장 데이터를 적용한 신뢰도 분석은 철도차량에 대한 새로운 유지보수 정책이나 유지보수 주기를 바꾸는데 매우 유용할 것이다.

This study was done to suggest basic modifications in the present situation for the family of women in labour which is a separation management method. The study design was a descriptive study. The number of the subjects were 80. they were husbands, mothers in law, and mothers of women in labour who were full term and for whom there were no complications, either for the mother or the fetus. Data collection was done with a structured questionnaire which was analyzed using frequencies. The results were as follows, 1. Most of the subjects(95.0%) wanted to participate in the labour process. 2. The subjects wanted to support the women in labour by way of encouraging(95.0%), consoling (95.0%), listening to(75.0%), praying with(68.8%), hand holding(97.5%), stroking(63.8%), helping with respiration control(50.0%), maintaining relaxation(46.3%), changing position(58.8%), and illustration (58.8 %). 3. The subjects answered that they expected their participation to have the effect of an easier labour course(52.5%), security for the women in labour(95.0%), and providing a better relationship between the women in labour(66.3%) and the new baby(55.0%). 4. The priority of the response as to who is the best supporter was husband, and mother of the women in labour in that order. It can be concluded that nurses maintained a management method which ignored the needs of the families of women in labour. If given consideration is to be given to these subjects, future programs should initiate ways to let the families participate in the labour process.

Purpose: The purpose of this study was to investigate the relationship between cell phone dependency and aggression in elementary school students with the mediating effect of leisure activities in South Korea. Methods: Data were cross-sectional in study design with 1,555 fourth grade elementary school students participating in the 4th-year Korean Children and Youth Panel Survey. Data analysis was performed using the SPSS/WIN 23.0 and AMOS 21.0 program. Results: Cell phone dependency has a significant effect on aggression, but it did not act as a control variable in the relationship between the protective factor, weekly book reading time and the amount of daytime play with aggression. Weekly entertainment time and weekly TV and video viewing time had a significant statistical effect on aggression, thus this study confirmed that cell phone dependency acts as a control variable in relation to aggression. Conclusion: As the entertainment time for elementary school students, the time spent watching TV and videos play a negative role, it is necessary to prepare a leisure activity management practice and strategies with an emphasis on entertainment time as well as, TV and video viewing as elementary school students' leisure activities for a healthy school life.

Purpose - This article tries to test if the conditional consumption capital asset pricing model (CCAPM) with bank credit for household as a conditional variable can explain the cross-sectional variation of stock returns in Korea. The performance of conditional CCAPM is compared to that of multifactor asset pricing models based on Arbitrage Pricing Theory. Design/methodology/approach - This paper extends the simple CCAPM to the conditional version of CCAPM by using bank credit for household as conditioning information. By employing KOSPI and KOSDAQ stocks as test assets from the second quarter of 2003 to the first quarter of 2018, this paper estimates risk premiums of conditional CCAPM and a variety of multifactor linear models such as Fama-French three and five-factor models. The significance of risk factors and the adjusted coefficient of determination are the basis for the comparison in models' performances. Findings - First, the paper finds that conditional CCAPM with bank credit performs as well as the multifactor linear models from Arbitrage Pricing theory on 25 test assets sorted by size and book-to-market. When using long-term consumption growth, the conditional CCAPM explains the cross-sectional variation of stock returns far better than multifactor models. Not only that, although the performances of multifactor models decrease on 75 test assets, conditional CCAPM's performance is well maintained. Research implications or Originality - This paper proposes bank credit for household as a conditional variable for CCAPM. This enables CCAPM, one of the most famous economic asset pricing models, to conform with the empirical data. In light of this, we can now explain the cross-sectional variation of stock returns from an economic perspective: Asset's riskiness is determined by its correlation with consumption growth conditional on bank credit for household.

The "Imwon Gyeongjeji(林園經濟志)", the largest encyclopedia of the Late Joseon Dynasty covers the details of the materials and construction methods related to everyday life's facilities. It is very useful to examine the "Imwon Gyeongjeji" for studying the materials and construction methods of the fences in traditional dwellings. Therefore, we tried to find the characteristics of the traditional fences exhibited in the "Imwon Gyeongjeji" by examining the construction methods shown in the book by structure of the fence. The results are as follow. First, the nine types of fence were listed in the "Imwon Gyeongjeji". Second, we could figure out the construction methods according to the structure of fences. The fence is divided into three parts: foundation, body, and roof. The body of the fence is a characteristic part distinguishing the types of fence. The foundation and the roof are related to the durability of the fence, regardless of the type of fence. The "Imwon Gyeongjeji" showed a robust manner in building fences than known today. Third, we found that the introductions and transformations of certain fence types. Fences such as Chuibyong(翠屛), Jeon Doldam(甎墻) and Bunjang were originated from China, yet has developed unique Korean styles in Joseon. It could also be seen that Kajo Zhang(哥窯墻) and Yonglong Zhang(玲瓏墻) were special fence types imported from China. It is not certain that the fences depicted in the "Imwon Gyeongjeji", represent the whole features of Joseon fences, but it is certainly an important literature to understand the structure and design of traditional fences of the Late Joseon Dynasty.

Bulcheonwi is determined by various ways. The first is certified by the state. Kings granted posthumous names to figures such as meritorious retainers, figures whose mortuary tablets were put into Jongmyo Shrine, and venerated figures with erudition and virtue whose mortuary tablets were put into Munmyo (Korean primary Confucian shrine The purpose of this study is to understand the spatial perception of Main head families (大宗家) and Sub head families (小宗家) have been divided for several centuries. This study was conducted under the assumption that it was possible to understand the mutual influence and relationship between perception and space by examining how methods for ritual ceremonies held in Main head families were conducted in different spaces of Sub head families or the process of ritual ceremonies changed with space. Bulcheonwi rites was performed by each family's own concepts of spaces such as Jeongchim or Cheongsa For actual ritual space, An-chae, Sarang-Chae and Byeoldang was utilized. This shows that one family's conception and utilization of each space was correspondent also different family s had their own idea of utilizing different spaces. In addition depends on the family in this study, there was differences on positon of Sa-dang upon the regions or time of construction. This can be concluded as familes had their own accommodations depends on building's space layout and traditons rather than following traditional Rites book's the rules of decorum.

Gordon Cullen, who tried to understand urban landscapes in terms of visual attention, introduced a concept called 'Space and Infinity' in his book 'Townscape'. According to him, urban images like infinity spreading across the sky are more effectively created when we happen to see an open space while walking along a ground-level street than when we look at the sky. This study aims to quantitatively examine if urban observers pay more attention to spaces like pilotis on the bottom of a building. Thus, this study collected observers on actual urban landscape images and partially-edited images and conducted an experiment by adopting Eye-movement Tracking to find out if they actually pay more visual attention to a space like pilotis. This study selected a total of 50 people as research subjects and divided them into two groups. Image 1 was shown to one group, and Image 2 with the pilotis space edited was shown to the other group. As an experiment to find objective evidences on Gordon Cullen's 'Space and Infinity', this study analyzed difference between Image 1 and Image 2, and it was found that the domain of pilotis showed a value five times higher than the average visual attention since it attracted much visual attention although it was very small in area. That is, it has objectively clarified that people get most fascinated with a place with infinite images in the background like a pilotis space out of all the urban landscapes as Gordon Cullen's theory. In addition, the differences in visual concentration of pilotis space by sex, by subject was examined, and there was no significant difference in visual concentration of pilotis space by gender. As a result of examining the difference of visual concentration by classifying the subjects into architectural related major, the major group showed higher frequency of viewing than the non - major group.

The purpose of this study is to get a more fundamental definition of the term Architecture and Geonchuk through analyzing the origin and reception of the terminus technicus Architektonike. In Latin world the greek term Architektonike was adopted and replaced the term Constructio by Vitruvius and has played a significant role in the history of architecture. In the late 19th Century however, the word Architecture was translated into Geonchuk(建築) and has been dominantly used in countries such as Korea, Japan, and China. But the difference of the denotation between them has not yet been fully evaluated. The term Geonchuk signifies much the same as the Tektonik and remains as such in the architectural discourse. In this context, this study goes back to refer to the philosophy of Metaphysics by Aristotle. In his book the term Architektonike was defined for the first time as terminus technicus, and the philosophies in later Ages of Leibniz or of Kant adopted it to signify the world view in accordance with the time. However, the original thought of the Architektonike disappeared in architectural practice and has been used in most cases as a substitute for Oikodomike which denotes house-building. The usage of this word in later time shows that it lost its foundation to be interpreted not only in terms of principium cognoscendi, but also in terms of principium reale. From this the literal usage of the term architecture and Geonchuk has seldom to do with its original meaning and denotation of Architektonike and also they lost the status of terminus technicus for the discourse of arche which encompasses the meaning of both principle and universal order.
