This research investigates whether product types moderate the relationship between e-tailer characteristics and shopping attitudes in the context of online category killer stores. To identify the antecedents of consumer attitudes for category killer stores, the product types are characterized by the two dimensions of hedonic and utilitarian. A total of 268 responses were collected from consumers who experienced online category killer stores. The results show that the quality of information contained in a website, customer review, relational benefits, and the expertise of the e-tailer are important determinants for shopping attitudes of consumers. Regarding the moderating effects of product types, hedonic value significantly moderates the relationships between shopping attitudes and relational benefits/e-tailer expertise. However, utilitarian value does not significantly moderate the relationships between shopping attitudes and any of the e-tailer characteristics. Theoretical contributions of this study are the findings of moderating effects of hedonic value on the relationships between e-tailer characteristics and shopping attitudes. In addition, this study practically implies how companies can utilize these characteristics strategically for marketing and the selection of products.

검색 결과 내 군집화(search-result clustering)는 검색 엔진으로부터 검색된 결과 내에서 비슷한 문서를 자동으로 군집화하는 기법이다. 본 논문에서는 논문 검색 서비스에 전문화된 새로운 결과 내 군집화 기법을 제안한다. 제안하는 시스템은 '범주체계생성기(Category Hierarchy Generation System)'와 '논문군집기(Paper Clustering System)'로 구성되어있다. '범주체계생생기'는 KOSEF의 연구 범주 체계를 이용하여 분야 시소러스라 불리는 범주 체계를 생성하고, K-means 알고리즘을 이용한 단어 군집화 알고리즘을 사용하여 분야 시소러스의 키워드 집합을 확장한다. '논문군집기'는 top-down 방식과 bottom-up 방식을 이용하여 각 논문의 범주를 결정한다. 제안하는 시스템은 논문 검색 서비스와 같은 전문 분야에 대한 검색 서비스에 유용하게 사용될 수 있을 것이다.

본 연구는 정치인의 종합적 이미지에 대하여 유권자가 가지고 있는 가치와 태도를 밝혀내고 유권자가 갖는 주관성의 구조를 심층적으로 알아보았다. 이러한 작업을 통하여 유권자의 정치적 행동에 미치는 영향력을 설명하는 것이 연구의 목적이다. 본 연구에서는 이재명 경기도지사 인식에 대한 3개의 유형이 도출되었는데, 제1유형(N=4) : 뚜렷한 원칙과 추진력 있는 개혁가, 제2유형[(N=12) : 실행력 있는 실용적 정책가, 제3유형(N=4) : 정치적 야망을 달성하고자 하는 포퓰리스트로 분류되었다. 제1유형은 이재명 경기도지사는 기득권의 장벽을 허물 수 있는 적임자라는 의견을 보였고, 제2유형은 성남시장 재임 중에 보인 행정능력으로 유권자 피부에 와 닿는 실용적 정책을 펼칠 것으로 기대를 가지고 있었으며, 제3유형은 현실성이 떨어지는 주장으로 자신의 정책과 태도만 부각시켜 인지도를 높이고 인기만 끌려는 태도에 우려를 표시했다.

In general, neural networks are widely used for the category classification of multispectral images. Since the input multispectral images into neural networks we, however, low contrast images, neural networks converge very slowly and are of bad performance. To overcome this problem, we propose a new image enhancement method which consists of smoothing process, finding the main valley and enhancement process. In addition the enhanced images by the proposed method are used as the input of neural networks for the category classification. When the new category classification method is applied to multispectral LANDSAT TM images, we verified that the neural networks converge very lastly and that the overall category classification performance is improved.

Objectives: The purpose of this study was to focus on the phenomenon of spouses experienced by offenders after completing the offender intervention program. Method: For this purpose, among the offenders who received the decision of counsel (counseling order) accused by domestic violence, who the other spouse selected case without counseling. After the in - depth interviews with the 9 participants, the collected data were analyzed by Colazzi 's phenomenological study method. Results: Major research findings can be summarized as follows. Category 1 was "Experiences about causes of violence", category 2 was "Experiences with forms of violence", category 3 was "What I wanted about my spouse when I called the police", category 4 was "What I wanted for myself when I reported to the police", category 5 was "the situation of the offender after completing the offender intervention program", category 6 was "what I experienced after completing the offender intervention program" and category 7 was "Experiences for Follow-up consultation needs". Conclusions: Based on the results of the research, counseling for perpetrators who are violent actors needed a therapeutic approach not only to strengthen the temporary punishment but also to help the family recovery on a continuous and sustainable level. Therefore, the implications of policy intervention for domestic violence were suggested.

근대 산업혁명 이후 도시 내 하천은 개발의 압력에 의해 점차 복개되고 사라져 도시 자연생태계의 기반이 되는 기능이 훼손되기 시작하였다. 중랑천 현지조사에서 조사지역내에 3회에 걸쳐 조사한 식물목록은 총 64과 179속 230종 36변종 1품종 1아종 등으로 총 268분류군으로 조사되었다. 연구대상지 출현식물의 상대 우점도를 분석한 결과 2차 조사에서는 참새귀리 22.97, 쑥 16.76, 개망초 15.89 등으로 나타났으며, 3차 조사에는 바랭이 26.78, 단풍잎돼지풀 16.29, 미국쑥부쟁이 14.31 등으로 조사되었다. 현지조사를 통해 연구대상지에 출현한 귀화식물은 총 54종이었다. 분석 결과 1년생 23분류군(43%), 2년생 11분류군(20%), 다년생 17분류군(31%), 목본 3분류군(6%) 등으로 나타나 우리나라 귀화식물 생활형과 유사한 값을 보였다. 귀화식물을 원산지별로 분석한 결과 북미와 유럽의 귀화종 비율이 76%이상이었다. 귀화도 5가 22분류군(41%)로 가장 높게 나타났고, 귀화도 3이 19분류군(35%), 귀화도 2가 8분류군(15%), 귀화도 4가 5분류군(9%) 순으로 조사되었다. 중랑천의 식물상은 아직도 10여년 전의 모습과 변화가 없다. 중랑천은 시민들을 위한 편의시설 확충과 수질개선은 이루어졌으나, 중랑천의 자연환경과 친수경관적 측면에서는 시급히 생물 다양성을 높이기 위한 노력이 필요하다고 판단된다.

Objective : Globus pallidus interna (GPi) is acknowledged as an essential treatment for advanced Parkinson's disease (PD). Nonetheless, the neurotransmitter study about its results is undiscovered. The goal of this research was to examine influences of entopeduncular nucleus (EPN) stimulation, identical to human GPi, in no-lesioned (NL) rat and 6-hydroxydopamine (6-HD)-lesioned rat on glutamate change in the striatum. Methods : Extracellular glutamate level changes in striatum of NL category, NL with deep brain stimulation (DBS) category, 6-HD category, and 6-HD with DBS category were examined using microdialysis and high-pressure liquid chromatography. Tyrosine hydroxylase (TH) immunoreactivities in substantia nigra and striatum of the four categories were also analyzed. Results : Extracellular glutamate levels in the striatum of NL with DBS category and 6-HD with DBS category were significantly increased by EPN stimulation compared to those in the NL category and 6-HD category. EPN stimulation had no significant effect on the expression of TH in NL or 6-HD category. Conclusion : Clinical results of GPi DBS are not only limited to direct inhibitory outflow to thalamus. They also include extensive alteration within basal ganglia.

Reward-based crowdfunding is a funding platform that allows funds to be raised to early operators who have lack of funds, and is seen as an outstanding infrastructure that is going to lead the fourth industrial revolution in that it is a field of realization of new technologies and creative ideas by start-ups. Reward-based crowdfunding has grown in line with the trend of the fourth industrial revolution, and funding success cases are taking place in various industries that culture/art to technology/IT, including as a new means of knowledge management in a rapidly changing industrial environment. The study focused on the fact that consumer's donation purposes may also vary depending on the category of projects classified as reward-based crowdfunding. Because consumer payment decisions and motivation of consumer purchasing behavior are classified according to the purpose of purchase, the previous papers that the goal gradient effect that the main motivation of consumer donation for reward-based crowdfunding introduced vary depending on project category of utilitarian and hedonic. In this study, consumer's daily donation data is collected by Indiegogo which is a leading reward-based crowdfunding company using web-crawling and the model was defined as propensity score matching (PSM) and random effect model. The results showed that the goal gradient effect occurred in utilitarian project category, but no goal gradient effect for the hedonic project category. Furthermore, this paper developed the study of motivation of consumer donation and contributes theoretical foundation by the results consumer donation may vary depending on the project category; also, this paper has implications for an effective marketing strategy depending on the project category leaves real meaning to the projector.

A systematic classification of Korean traditional patterns has been made according to their objects and presenting methods. The classification is represented with 3 levels of categories. First, the superordinate category is composed of 7 groups of patterns, i.e. Naturals, Animals, Plants, Artifacts, Geometric, Composites, and Others. Second, the basic category is composed of motifs in each group. Third, the subordinate category is composed of 3 types, i.e. realistic, stylized, abstracted, according to the degree of simplification. As this classification is a method for organizing informations in Korean traditional patterns in a systematic way, it can offer a useful basis for computerization of the patterns.
