This study investigates the impact of organizational socialization tactics on newcomers' organizational citizenship behaviors. We explains this relationship with the concept of perceived organizational support, which refers to the extent to which individuals perceive that the organization recognizes their contributions and takes care of their well-being. We expect that the more institutionalized the organization's socialization tactics are, the more organizational support individuals perceive, consequently increasing the performance of organizational citizenship behaviors. We performed a survey targeting 450 newcomers in domestic companies, and adopted 382 data for path analyses based on the structural equation modeling. As the result, in all the three dimensions of socialization tactics (content, context, social), the extent to which socialization tactics are institutionalized is positively related to the perception of organizational support. It also has the positive relationship with individuals' organizational citizenship behaviors, being fully mediated by the perceived organizational support. More specifically, context socialization tactics shows the highest level of impact both on the perceived organizational support and organizational citizenship behaviors, whereas social tactics has the lowest level of impact. These results imply that the range of effects the organizational socialization has on the newcomers' attitudes and behaviors should be more extended and detailed.

The objective of this study was to empirically analyze the effect that the perceptions professionalism perceived by social workers at local child care centers wold have on organizational commitment. For this study, the social workers at local child care centers in Jeollanam-do were surveyed. 286 sets of questionnaires were used for analysis among the collected ones, excluding the missing values. The results of analysis showed that the professionalism score was above the medium level while the service conviction score was found to be the highest. A positive(+) correlation was observed between perceptions professionalism and organizational commitment. Particularly, the correlation was the highest between occupational consciousness of mission and organizational commitment. Meanwhile, the results of multiple regression analysis suggested that the organizational commitment was affected by occupational consciousness of mission and utilization of professional organization, the sub-variables of perceptions professionalism. Moreover, it was found that the occupational consciousness of mission had the greatest influence on organizational commitment. Based on aforesaid results of analysis, this study presented the direction for the improvement of perceptions professionalism and organizational commitment among social workers of local child care centers, along with the challenges for the succeeding studies.

The prior purpose of this study is to introduce a optical biopsy and evaluate whether the optical biopsy, real-time, non-invasive technique, is a reliable tool to assess response to radiotherapy Four healthy volunteers, and four patients with inflammatory conditions of the oral cavity participated on the study. was obtained from each person enrolled in the study. Using FastEEM(Ercited Emission Matrix) as a optical biopsy tool, normal and tumor spectra are taken from the normal and the tumor regions. And then second optical biopsy are taken from the tumor regions in 4 patients with time delay at 7days.. Using a diagnostic algorithm, made by Gillenwater based on spectra excited at 337nm The Optical Biopsy turned out to be more suited for tumor diagnostic resulting in significant difference fluorescence spectra. The fluorescence intensity of cancerous tissue showed a higher position. The second fluorescence intensity of optical biopsy of cancerous oral tissue has more smaller than the first result. I conclude that optical biopsy, which technique don't need to remove tissue sample from body, and is a real time , and non-invasive measurement is a reliable tool to access to radiotherapy because FastEEM can do measure the variation of the tissue composition chemical, biological, and morphological after radiotherapy. Based on the fluorescence spectrum are taken from the optical biopsy in normal and tumor spectra as well as tumor spectra after 7days.

In order to do a meta-analysis, a total of 27 journals, theses and dissertations published between 1998 and 2020 were reviewed systematically. Through this process, this study calculated average effect size of each variable and explored moderator variables. This study results were as follows. First, this study identified a total of 14 individual, enviroment of institution, population variables related with case management performance. Second, the results indicated that case management performance variables which showed large effect sizes included professional capability, supervision, network, case management significance recognition, manual, agency support. Third, variables with medium effect sizes included self-efficacy, case management education, autonomy, motivation, number of conference and variables with small effect sizes included work experience, academic ability, age. Fourth, Moderator effects were identified in the field, target, publication of case management. Finally, the implications of the study findings were discussed.

현재 시판되고 있는 치과용 76.5%Pd-11.6%Cu-7.2^%GarP 합금의 주조상태 및 임상열처리에 따른 미세조직의 변화를 X-선 회절기, 광학현미경, 시차열분석기를 이용하여 관찰하였다. 주조상태, 탈개스 및 세리믹소성처리 후 미세조직은 Pd고용체와 금속간화합물 Pd2Ga으로 구성되어 나타났고, 이들 상들은 열처리에 따라 상당한 변화를 보였다. 또한 Pd은 아르곤 분위기 내의 산소와 반응하여 산화물 형성 및 분해로 인해 질량변화곡선(TG)이 변하였고, 시차열분석(DTA)에서는 약 815$^{\circ}C$ 정도에서 Pd2Ga에 기인하는 흡열피크를 확인하였다. 이러한 실험의 결과들은 Cu가 이원계 Pd-Ga 합금의 Ga의 고용량을 낮추어 공정반응이 저 Ga 쪽으로 이동하기 때문인 것으로 설명하였다. 그러나 앞으로 보다 명확한 상변태 규명을 위해서 TEM등의 분석장비를 사용하여 체계적인 연구가 요구된다.

This study examines runaway youths at risk in a youths' shelter who are preparing for an independent life and both the facilitating and adverse factors to personal characteristics and independence of runaway youths at risk with the aim to grasp their recognition of independence and level of desire for it and find out necessary factors for a successful independence in multidimensional perspectives including the economic independence, educational independence, psychological independence, and social independence for their sound growth. This will provide the basis for desirable interventions for youths runaway youths at risk to prepare for an independent life. The findings of this study on the factors that affect the preparation for an independent life are as follows: First, as a result of analyzing the effect of micro-systematic factors on the preparation for an independent life, it turned out that problem-solving abilities and self-efficacy had influence on the preparation for a career Second, as a result of analyzing the effect of mesoscopic-systematic variables on the preparation for an independent life, it turned out that the preparation for a career were affected by whether to participate in independence preparation programs and institutional supports, and that career maturity of runaway youths at risk were affected only by the relationship with teachers and participation in independence preparation programs. Third, as a result of analyzing the effect of macro systematic variables on the preparation for an independent life, it turned out that the preparation for a career were affected by participation of the local community and service network, and that participation of the local community was an predictor variable that would affect a career maturity of runaway youths at risk. Fourth, as a result of analyzing ecological systematic variables that might affect the preparation for a career, it turned out that intervening variables and macro systematic variables had the most powerful influence on the preparation for a career among runaway youths at risk. It is necessary, therefore, to provide education programs organized by policies in order to develop problem-solving abilities and vocational capabilities so that runaway youths at risk, and to train and appoint more professional teachers at shelters. Programs for independence preparation need to be developed actively and practically in consideration of the characteristics of shelters, and the network with the local community for support also need to be established in utilization of the human resources and service programs of the community. With the understanding of leaving home of runaway youths at risk as the previous stage of an independence, there should be a housing support for their stable settlement in the perspective of housing welfare until become adults. In addition, there should be education specialized programs for occupation and careers to train runaway youths at risk as professionals including such areas as health, mentality, learning, and voluntary work for their sound growth.
