  • Retained austenite in matrix of austempered ductile iron has been well-known as a parameter in controlling mechanical properties, but investigation to obtain quantitative relationship with mechanical properties lack. Therefore, this study executed austempering treatment at various temperatures on ductile iron alloyed with Mo, Ni, Cu. In consequence, microstructure of retained austenite transformed coarse, and quantity increased according as austempering temperature increased. After heat-treatment, microstructure of specimen alloyed with Ni was fine, and toughness improved. At austempering temperature up to $400^{\circ}C$, carbide precipitation started in retained austenite. In consequence, afforded cause of hardness increase, a lot of increase did not arise for coarse structure.

  • This study aimed to examine the cause and consequence of emotional labor strategies based on the emotional labor framework. To investigate the boundary condition of the current research model, the study proposed that job autonomy would moderate the effects of emotional labor on employees' well-being. To achieve the purpose of the study, it was first tested whether neuroticism and extroversion of employees predicted the focal outcomes (i.e., burnout and work engagement) via distinct emotional labor strategies. Second, the moderation effects of job autonomy were tested for each emotional labor strategy in predicting the focal outcomes. Third, the conditional indirect effects of job autonomy on the mediation process were examined. The results revealed that surface acting partially mediated the relationship between neuroticism and burnout, whereas deep acting fully mediated the relationship between extraversion and work engagement. Regarding the moderating effects of job autonomy, it significantly moderated the relationship between surface acting and burnout and between deep acting and work engagement. In addition, from the moderated mediation effects, the conditional indirect effects of job autonomy were significant. Finally, theoretical and practical implications are discussed and limitations and future research directions were suggested.

  • This study was to explore the living experiences of the disabled adults who were participating in public education Yahak program held at evening class. The study designed in-depth interviews with ten disabled people using a grounded theory approach. Through analyzing process, 34 concepts, 15 subcategories, and eight categories were deduced. In axial coding, casual condition, 'Suffering from unknown cause disabilities' and 'Isolated by social cause', context condition, 'Taking discriminative treat for disabilities' impacted on phenomenon, 'Overcoming their conditions by themselves'. Intervening conditions was 'Taking social supports' and action-interaction condition, 'Enjoying public programs' totally lead to consequence in 'Controlling daily life' and 'Exploring their own social roles'. The periods of process were divided three stages, reflecting disabled situation, formation phase of social relation, and self-developing phase. The core category, 'Trying to be recognized as a member of society' incorporated the relationship between and among all categories and explained the process. The study indicates that social education program for the disabled helped to develop themselves as a member of society. Therefore, we suggest there may be a need for training for professionals who work with disabled people to develop social adaptation.

  • AGNPS model is applied in this study to analyze the changes of non-point source pollutant according to AMC condition using probable rainfall. Probable rainfall of H-dam area by Gumber's extreme value distribution is computed through frequency analysis for each return period. 35 coarse grids are subdivided into 134 find grids of finite differential network to analyze peak flow soil loss quantity and nutrients of study area and the modified CN estimation equation shows good result about rainfall events-peak flow relationship. And as the consequence of estimation of soil loss quantity for each rainfall event soil loss quantity shows 120%-170% of actual soil loss quantity Regression analysis for the observed and calculated values of flow T-P AMC has an important effect on nutrients concentration of outflow and it if found that the excessive fertilization under AMC III condition may cause eutrophication by nutrients because the range of increase of outflow concentration appears relatively high.

  • 이 연구는 강 절도 범죄의 공범실행 과정을 전반적으로 살펴보는데 그 목적이 있다. 이를 위하여 2013년 한국형사정책연구원에서 '공범 있는 범죄의 구조와 특성에 관한 연구: 강 절도를 중심으로'를 수행하기 위해 수집된 심층 면접 자료를 이차자료로 활용하였으며, 이차자료를 통해 근거 이론적 접근을 시도하였다. Strauss&Corbin(1990)이 제시한 절차에 따라 사례를 분석한 결과, 개방코딩 단계는 51개의 개념과 22개의 하위 범주, 8개의 상위 범주가 도출되었다. 축코딩 단계는 '코딩 패러다임(coding paradigm)'이라는 분석도구에 따라 인과적 조건은 강 절도 범행원인이다. 맥락적 조건은 공범관계 형성과 공범선택 이유이다. 중심현상은 강 절도 공범실행이다. 중재적 조건은 공범 간 갈등과 검거요인 발생이다. 작용/상호작용 전략은 공범 모두 검거이다. 결과는 공범관계 종료로 구성되었다. 마지막으로 선택코딩 단계는 '공범관계 형성과 종료 사이의 갈등전개'를 핵심범주로 선정하였고, '형성-실행-갈등-검거-종료'라는 과정을 통하여 강 절도의 공범관계를 새롭게 정립하였다.

  • Purpose - The objective of this paper is to discover if there exists a relationship between the economic index and distribution industry index in Korean. Because of the distribution industry boom in the recent years, a lot of interest in the relationship between the economic index and distribution industry index in Korean and the economy has been generated. This article examine on the mutual influence between economic index and distribution industry index in Korean. Research design, data, and methodology - For this purpose, we use the vector-auto regression model, impulse response function and variance decomposition of the economic index and distribution industry index, Granger causality test using weekly data on the economic index and distribution industry price index in korea. The sample period is covering from January 2, 2010 to August 31, 2019. The VAR model can also be linked to cointegration analysis. Cointegration Analysis makes possible to find a mechanism causing x and y to move around a long-run equilibrium (Engle and Granger, 1987). This equilibrium means that external shocks may separate the series temporarily at any particular time, but there will be an overall tendency towards some type of long-run equilibrium. If variables are found to have this tendency they are said to be cointegrated and a long-run relationship between these series is established. These econometric tools have been applied widely into economics and business areas to analyze intertemporal linkages between different time series. Results - This research showed following main results. First, from the basic statistic analysis of the economic index and distribution industry index in Korean, the economic index and the distribution industry index in korea have unit roots. Second, there is at least one cointegration between the economic index and distribution industry index in Korean. Finally, the correlation between of the economic index and the distribution industry index in korea is (+) 0.528876. Conclusions - We find that the distribution industry price index Granger cause the economic index in korea. As a consequence, the distribution industry index affect the economic index in Korean. The distribution industry index to the economic index is stronger than that from the economic index to the distribution industry index.

  • The purpose of this study is to find the complementary idea of the psychological elements in aesthetic expression of architectural space in the sense of healing. Marks $L\ddot{u}scher$, the swiss psychologist suggested reasonable categories of emotional character according to the couple combinations among Content, Self-Esteem, Confidence, and Liberty. His theory on healing is not only the concept but the practical method to understand and control the conflict between contrary elements of emotion. Compared to the Freud's objective theory of cause and consequence, his idea is focused on the subjective and autonomous harmony. This theory based on complementary idea is applied to psychological attitude of architects on Spatial Expression in this study. Refuge, Prospect, Flow and Void are assumed as equivalent spatial elements to the four major emotional conditions suggested by $M.L\ddot{u}scher$. The couple combinations among them also characterize the architectural characters definitely and it is expected to be the reasonable criteria in analysing aesthetic value and motive of creating human space.

  • The potato has been used as a part of key staple foods in Korea. Recently, the demand for the potato tends to increase due to its nutritional Quality, and the Quantity of imports has rapidly been increasing. Contamination of seed potato by pathogens especially could cause a severe reduction of total production. In order to solve the problem, Korea Research Insistute of Bioscience and Biotechnology(KBIBB) developed the new commodity called a "potato microtuber". Before its production and distribution, researches on new commodity should be undertaken in many aspects, especially in terms of economic aspects. The main objectives of this study are to measure the economic value of the potato microtubers and to forecast its spreading effects and to examine the Contingent Valuation Method(CVM) could be accepted in the economic analysis for a new agricultural product, here in potato microtubers. Through the regression results, the consumer behavior analysis had performed for potential users of potato microtubers, and through the demand function derived by the consequence of functional relationship, consumer's surplus was estimated.
