  • Many objects are always present in a visual scene. Since the visual system has limited capacity to process multiple stimuli at a time, how to cope with this informational overload is one of the important problems to solve in visual perception. This study investigated the suppressive interactions among multiple stimuli when attention was directed to either one of the stimuli or all of them. The results indicate that suppressive interactions among multiple circles were reduced in V4 when subjects paid attention to one of the four locations, as compared to the unattended condition. However, suppressive interactions were not reduced when they paid attention to all four items as a set, in order to compute their mean size. These results suggest that whereas focused attention serves to later out irrelevant information, distributed attention provides an average representation of multiple stimuli.

  • The purposes of this article are to criticize social services, and to consider alternative caring policies and social economic regime to cope with caring blank, in the view point of A. Gorz. According to Gorz, in the value of growth of capitalism, people who are in charge of household affairs and caring work make inroads into the wage market. At this point, as caring blank is occured, social services are emerged. These new aspects are 'Commodification and Rationalization of Private Life'. This article suggests alternative ideas to these aspects. First, universal care giver·breadwinner model, second, the dominance of eco-reason and shorter working hours.

  • This study was conducted to investigate nursing students' safety-climate: perception and performance of standard precautions for healthcare-associated infection control. We also identified actors influencing performance of standard precautions. Data were collected from 246 junior and senior nursing students at nine colleges in D city from July to September, 2016. The mean score of performance was significantly lower than that of perception in all areas of standard precautions. The biggest difference between perception and performance was in the usage of personal protective equipment and safe injection practices. We also detected significant positive correlations among safety-climate, perception, and performance of standard precautions. In the regression analysis, performance of standard precautions was influenced by safety-climate and grade accounting for 10.7% of variance. To improve healthcare-associated infection control among nursing students, safer and more supportive practical environments need to be provided, and new training strategies such as simulation education need to be expanded.

  • 본 논문에서는 한글과 영문 문서 영상들에 대한 기울어짐 추정(skew estimation) 알고리즘을 제안한다. 제안 방법은 전체 문서 영상에서 텍스트 요소들이 밀집되어 있는 영역을 선별하고, 선별된 영역에 대해 허프 변환을 적용하는 선택적 주의집중(selective attention) 방식을 채택한다. 제안 방법의 기울기 추정 과정은 2단계로 구성되는데, coarse 단계에서는 전체 영상을 몇 개의 영역으로 나누고 동일한 영역에 속하는 데이타들간의 연결 각도를 계산하여 각 영역별 accumulator에 저장한다. accumulator에 저장된 빈도치를 기준으로 $\pm$45$^{\circ}$범위 내에서 최대 $\pm$1$^{\circ}$의 오차를 가진 각 영역별 기울기를 계산한 후, 이들 중 최대 빈도값을 갖는 영역을 선정하고 그 영역의 기울기 각도를 문서 영상의 대략적인 기울기 각도로 결정한다. Refine 단계에서는 coarse 단계에서 선정된 영역에 허프 변환을 적용하여 정확한 기울기를 계산하는데, coarse 단계에서 추정한 기울기의 $\pm$1$^{\circ}$범위 내에서 0.1$^{\circ}$간격으로 측정한다. 이와 같은 선택적 주의집중 방식을 통해 기울기 추정에 소요되는 시간 비용은 최소화하고, 추정의 정확도는 최대화 할 수 있다.제안 방법의 성능 평가를 위한 실험은 다양한 형태의 영문과 한글 문서 영상 2,016개에 적용되었다. 제안 방법의 평균 수행 시간은 Pentium 200MHz PC에서 0.19초이고 평균 오차는 $\pm$0.08$^{\circ}$이다. 또한 기존의 기울기 추정 방법과 제안 방법의 성능을 비교하여 제안 방법의 우수성을 입증하였다.Abstract In this paper we propose a skew estimation algorithm for English and Korean document images. The proposed method adopts a selective attention strategy, in which we choose a region of interest which contains a cluster of text components and then apply a Hough transform to this region. The skew estimation process consists of two steps. In the coarse step, we divide the entire image into several regions, and compute the skew angle of each region by accumulating the slopes of lines connecting any two components in the region. The skew angle is estimated within the range of $\pm$45 degree with a maximum error of $\pm$1 degree. Next we select a region which has the most frequent slope in the accumulators and determine the skew angle of the image roughly as the angle corresponding to the most frequent slope. In the refine step, a Hough transform is applied for the selected region within the range of $\pm$1 degree along the angle computed from the coarse step, with an angular resolution of 0.1 degree. Based on this selective attention strategy, we can minimize the time cost and maximize the accuracy of the skew estimation.We have measured the performance of the proposed method by an experiment with 2,016 images of various English and Korean documents. The average run time is 0.19 second on a Pentium 200MHz PC, and the average error is $\pm$0.08 degree. We also have proven the superiority of our algorithm by comparing the performance with that of other well-known methods in the literature.

  • This study purports to explore potential determinants of welfare attitudes toward universalism vs selectivism. For this purpose, literature review upon such subjects as definitions of universalism and selectivism and welfare attitudes has been done. The hierarchical regression analyses show several major results. First and foremost, the effects of those variables such as political orientation and attitudes toward free education and gratuitous child care, categorized as political-social stance were found to be significant. However, it was unexpected results that those variables which have been found signigicant in predicting welfare attitudes in previous literature, that is to say age, education and economic status especially were not to be found significant in predicting welfare attitudes toward universalism vs selectivism. There could be many underlying causes for this result including measurement errors, and this study strongly speculates that the division between universalism vs selectivism itself exists only both in purely conceptual level and in political rhetoric and therefore, universalism or selectivism as people's consistent and logical attitudes or consciousness may simply not exist at all.

The Dynamics of British Welfare Pluralism from Post World War II until the New Labour Government: Personal Social Service Policy for the Elderly (제2차 세계대전 이후부터 신 노동당 정부까지 영국의복지 다원주의의 역동성: 노인을 위한 개인적 사회 서비스 정책을 중심으로)

  • The purpose of this research is both to analyse the dynamics of welfare pluralism in the personal social service policy for elderly British people and to provide policy implications based on analysis of the post World War II time era up until the end of the New Labour Government. Content analysis of government and parliament reports, minutes, scripts for party conferences, legislations, declassified government documents, and institutes' reports of the Conservative, Labour, and New Labour Governments from 1945 to 2010 shows that the governments played only assistive roles in welfare pluralism at any given point in time. The negative experiences of elderly British can be attributed to the unbalanced structure of roles held by public and private institutions for personal social services. They ultimately have important policy implications for the foundation of welfare pluralism in elderly Korean community care by the Moon Jae-in government.

  • Korean studies are in crisis because they have fallen prey to the territorial trap associated with methodological territorialism and methodological nationalism. In order to overcome this situation, this paper suggests the studies on Korea to be more active in accepting the socio-spatial perspective that emphasize the inseparability of society and space. In particular, paying special attention to the 4 important dimensions of socio-spatial relations, such as place, territory, network and scale, it examines the ways in which these 4 dimensions are overlapped, interconnected and dynamically interacting with one another from the perspective of "multi-scalar networked territoriality". In conclusion, I argue that the Korean studies need to understand the variegated and multi-scalar nature of Korea, a place, which is constituted through complex interactions among diverse political, social, economic and cultural forces and processes that operate in various places and at diverse geographical scales.those days, such as agriculture, crops, and transportation of goods. Fifth, the bibliography and citations explaining all instances reveal that China (Qing) is a great civilization of the advanced world and that the scholarship of Joseon relied on and accepted it. Sixth, except for horse raising and management, farming implements for rice transplantation, sericulture, and natural dying of cloth, most of the topics are useful even today. In short, theres is a profound aspect to the content that makes it possible to estimate the "geographical thinking". In general, the focus of the content of this book directly linked to the practical agricultural economy of the common people.

  • The goal of this study is to compare entrepreneurial orientation of both countries' students and to compare the effect of individualism on developing entrepreneurial orientation of both countries. In order to achieve this goal, this study will conduct two analysis. Firstly, the comparative study on entrepreneurial orientation of both students will be implemented by conducting F-test and t-test. Secondly, the regression analysis between an independent variable - individualism - and dependent variables - innovativeness, internal locus of control, and entrepreneurial orientation - will be conducted in order to compare the effect of individualism on developing entrepreneurial orientation. Prior to implementation of two analysis, this study has implemented the survey to Korean and Chinese university students to estimate entrepreneurial orientation and a cultural variable to influence entrepreneurial orientation. The question of survey is divided into two parts - individual entrepreneurial orientation including internal locus of control and innovativeness and a cultural variable, individualism. As other precedent comparative studies of Chines and Korean potential entrepreneurship concluded, Chinese students have shown higher entrepreneurial orientation than Korean students. However, on the contrary to prior studies on cultural factors and entrepreneurship, only Chinese students' entrepreneurial orientation is influenced by individualism. Any dependent variables of Korean students were not affected by individualism variable.
