The purpose of this study is to provide the useful reference to establish the system improvement plan that activates the counseling service quality for the disabled parents peer counselors. The qualitative case study method of Yin (2009) has been used to understand and reflect to the system for the experience of field counseling of the peer counselors for the disabled parents. 10 parents peer counselors for the disabled were proportionately sampled and interviewed about their experiences through a FGI and two individual interviews. The result of the study derived from total 87 abstract concepts and 17 categories and personal motivations for participating and changes from the experience are as follows: the effects of counseling are “mutual sympathy toward the same disability,” “Identity transformation from nobody to somebody who gives hope,” and “another social insurance and social safety network that parents disability make.” The barrier facts for the parents peer counseling activation are: “problem of securing the position of the counseling site” and difficulty in finding the client due to lack of awareness and publicity. “The study suggests four programs to upgrade the parents peer counseling: (1) To secure the position of the counseling site, (2) To reestablish the status as a professional counselor. (3) The need of pokicy supplement and support from the government, (4) The expectancy of creating jobs through the conversion of full-time workers. 본 연구의 목적은 장애인상담현장의 장애인부모동료상담서비스 활성화를 위한 제도개선 방안 및 시스템구축을 위한 기초자료를 제시하기 위하여 장애인부모 동료상담사들의 현장상담경험을 Yin (2009)의 질적 사례연구방법을 활용하여 수행하였다. 이를 위하여 장애인부모 동료상담사 10명을 대상으로 FGI와 개별심층면담을 실시하여 자료를 수집하고 분석했다. 연구결과, 총 87개의 압축개념, 17개의 핵심범주를 도출하였는데 장애인부모동료상담 참여 동기 및 상담효과는 “동병상련의 마음으로 두드림”, “조명 받지 못하던 존재에서 희망을 주는 존재로의 전환”, “장애인부모들이 만드는 또 다른 사회보험이자 사회안전망” 등으로 나타났다. 장애인부모동료상담활성화 장애요인은 “상담현장의 입지확보 및 위상정립의 문제”, “홍보부족으로 인지도가 낮아 내담자 발굴이 어려움” 등으로 나타났으며, 장애인부모동료상담 활성화를 위한 전략은 “현장의 입지확보와 전문가로써의 위상 재정립”, “정부의 정책적인 보완과 지원이 필요함”, “정규직 전환으로 일자리 창출을 기대함”이 제시되었다.

An architecture is a vessel containing a people's life. A life's paradigm could be made by values of the times and when the technical expertises are added to such a paradigm, thereby the architecture is finally made. Therefore an architecture is a favorite of the time's cultural arts. Such an architecture can not maintain the vital power as a real architecture if the architecture does not continue a people's life. Furthermore, while the time goes by and the building's functions change, the space no longer can perform the functions and happens to be abandoned and alienated. The architecture which is not well defined and misused needs to be renovated in the sense of recycling the city. Even more in case the architecture has a historical and cultural preservation value, the renovation for a proper use of the architecture is much more important. The modern time's street in Incheon is a historical spot which shows Korean modern architecture style. Nevertheless, the people's understanding for a preservation and proper use is quite low, because of a lack of historical definition about the modern times. Hence, in the case of building which is owned by private, sometimes it is heartbreakingly removed and demolished because of some monetary reasons. According as the industry prospered in this area declined and the center of city is moving, development for an actual use of this area's buildings are desperately needed. This study has focused that the modern buildings having value of the preservation in Incheon should be used more actively through a renovation. An architecture is a vessel containing a people's life.

본 연구는 서울시 지정 다문화통합 어린이집 보육교사를 대상으로 다문화통합 어린이집 지원 인식에 따른 다문화정책향성, 다문화수용성, 다문화역량의 차이를 알아보고, 보육교사 다문화정책지향성에 따른 다문화수용성, 다문화역량은 차이가 있는지 알아보려 한다. 본 연구는 서울시 지정 다문화통합 어린이집에서 근무하는 교사 163명을 대상으로 하였다. 수집된 자료는 SPSS 22.0 프로그램을 사용하였다. 본 연구의 결과는 첫째, 다문화통합 어린이집 지원 인식에 따라 다문화정책지향성의 경우는 차이가 있었는데, 다문화교육 경험, 외국인과 의 활동경험, 다문화통합 어린이집 소속에 대한 인식에 따라 차이가 있었다. 다음으로 다문화통합 어린이집 지원 인식에 따른 보육교사의 다문화수용성의 경우, 기관 지원동기여부, 관련 프로그램 실행여부 등에 따라 차이가 있었다. 또한 다문화통합 어린이집 지원 인식에 따른 다문화역량의 경우, 다문화 교육 경험 여부, 다문화통합 어린이집 소속에 대한 인식, 기관 지원동기여부, 다문 화통합 어린이집 지원내용인식, 관련 프로그램 실행여부 등에 따라 차이가 있 었다. 둘째, 다문화정책지향성에 따른 다문화수용성 수준의 차이는 차별․배제주 의에 대한 인식이 낮은 교사가 관계성 수용 수준이 높았고, 동화주의에 대한 인식이 높은 교사가 다양성과 관계성 수용 수준이 높았으며, 다문화주의에 대 한 인식이 높은 교사가 다양성과 관계성 수용 수준이 높았다. 보육교사의 다문 화정책지향성에 따른 다문화역량 수준의 차이 검증 결과, 동화주의에 대한 인식이 높은 교사가 다문화역량 수준이 높았다. The purpose of this study is to investigate the overall perception of multicultural support for the multicultural integrated day care center teachers in Seoul and to find the differences in policy orientation, acceptance and competence. This study was conducted on 163 teachers who work in a multicultural integrated childcare center in Seoul. Collected data was analyzed by using SPSS 22.0 program. Firstly, the orientation of the multicultural policy varies with the perception of the supports for multiculturalism & integration childcare, specifically with the perception of multicultural education, experience of activities with foreigners, and affiliation with multiculturalism & integration childcare. The childcare teachers’ receptiveness toward multiculturalism varies with the perception of supports to multiculturalism & integration childcare, the motivation for agency’s support, and the implementation of related programs. In addition, the multicultural capabilities affiliated with the perception of the supports for multiculturalism & integration supports vary with the experience of multicultural education, the perception of the affiliation with multiculturalism & integration childcare, the motivation for agency’s support, the perception of supports for multiculturalism & integration childcare, and the implementation of related programs. Secondly, the differentiation of the level of the receptiveness toward multicultural policy orientation is such that teachers with poor awareness of discrimination and exclusionism registered a high level of a teacher’s receptiveness toward relationality, a higher level of receptiveness toward diversity and relationality among those teachers with an excellent awareness of assimilationism, and a high level of receptiveness toward diversity and relationality among those teachers’ with excellent awareness of multiculturalism. When we checked the differentiation of the multicultural capabilities affiliated with multicultural policy orientations, those teachers with an excellent awareness of assimilationism showed a high level of multicultural capabilities.

Neuroprotective Effects of N-Acetylglucosamine against Hydrogen Peroxide-induced Apoptosis in Human Neuronal SK-N-SH Cells by Inhibiting the Activation of Caspase-3, PARP, and p38

최하나,정미자,박제권,박용일 한국식품과학회 2013 Food Science and Biotechnology Vol.22 No.3

Neuroprotective effects of N-acetylglucosamine (GlcNAc), a monosaccharide derivative of glucose, against H2O2-induced neurotoxicity and its underlying mechanism in human SK-N-SH neuroblastoma cells were investigated. Pretreatment of GlcNAc prior to exposure of cells to H2O2stress significantly reduced the H2O2-mediated neuronal cell death and apoptosis. The GlcNAc dose-dependently decreased the level of intracellular reactive oxygen species (ROS) in H2O2-treated cells and also effectively inhibited H2O2-induced apoptotic features such as DNA fragmentation,caspase-3, and poly ADP-ribose polymerase (PARP) cleavages,and p38 phosphorylation. These results suggested that GlcNAc might potentially serve as agents for prevention of neurodegenerative diseases caused by oxidative stresses and this effect may be associated with the suppression of caspase-3, PARP, and p38 activation.

앙상블 SVM 모형을 이용한 기업 부도 예측

최하나,임동훈 한국데이터정보과학회 2013 한국데이터정보과학회지 Vol.24 No.6

Corporate bankruptcy prediction has been an important topic in the accounting and finance field for a long time. Several data mining techniques have been used for bankruptcy prediction. However, there are many limits for application to real classification problem with a single model. This study proposes ensemble SVM (support vector machine) model which assembles different SVM models with each different kernel functions. Our ensemble model is made and evaluated by v-fold cross-validation approach. The k top performing models are recruited into the ensemble. The classification is then carried out using the majority voting opinion of the ensemble. In this paper, we investigate the performance of ensemble SVM classifier in terms of accuracy, error rate,sensitivity, specificity, ROC curve, and AUC to compare with single SVM classifiers based on financial ratios dataset and simulation dataset. The results confirmed the advantages of our method: It is robust while providing good performance. 기업의 부도를 예측하는 것은 회계나 재무 분야에서 중요한 연구주제이다. 지금까지 기업 부도예측을 위해 여러 가지 데이터마이닝 기법들이 적용되었으나 주로 단일 모형을 사용함으로서 복잡한 분류 문제에의 적용에 한계를 갖고 있었다. 본 논문에서는 최근에 각광받고 있는 SVM (support vector machine) 모형들을 결합한 앙상블 SVM 모형 (ensemble SVM model)을 부도예측에 사용하고자 한다. 제안된 앙상블 모형은 v-조각 교차 타당성 (v-fold cross-validation)에 의해 얻어진 여러 가지 모형 중에서 성능이 좋은 상위 k개의 단일 모형으로 구성하고 과반수 투표 방식 (majority voting)을 사용하여 미지의 클래스를 분류한다. 본 논문에서 제안된 앙상블 SVM 모형의 성능을 평가하기 위해 실제 기업의 재무비율 자료와 모의실험자료를 가지고 실험하였고, 실험결과 제안된 앙상블 모형이 여러 가지 평가척도 하에서 단일 SVM 모형들보다 좋은 성능을 보임을 알 수 있었다.

The Influence of Threat Situation and Expectation on the Weapon Focus Effect in a Virtual Mock-Crime Video

최하나,이장한 한국자료분석학회 2016 Journal of the Korean Data Analysis Society Vol.18 No.4

This study aimed to investigate whether the eyewitness expecting to see a weapon would cause the weapon focus effect (WFE) in the threat or non-threat situation. Two video clips showing the presence or absence of a threat (crime or refund) were used. 80 participants were randomized within four conditions: threat and expected, threat and enexpected, non-threat and expected, and non-threat and unexpected. The expected group was provided with critical information about the incident before watching the video clip, while the unexpected group was not. To identify the occurrence of the WFE, eye-movement was measured while the participants were watching the interaction between two individuals in a crime scene or a refund scene; then, a memory recall test and a photo line-up test were conducted at the end of the experiment. Our results indicate that the threat and unexpected condition showed a significantly longer dwell time on the weapon than did other conditions. Therefore, our results suggest that participants’ expectancy to see a weapon can be reduced in the WFE, but the threatening situation will still cause the WFE.
