Habruta is a question-based learning that talks, discusses, and argues in pairs. In particular, the famous painting Habruta is being implemented for the purpose of enhancing the appreciation ability of paintings and enriching the expressive power through questions and answers about the famous paintings. In this study, in order to support the famous painting Habruta for oriental paintings, we propose a method of automatically generating questions from the gender perspective of oriental painting characters using the current deep learning technology. Specifically, in this study, based on the pre-trained model, VGG16, we propose a model that can effectively analyze the features of Asian paintings by performing fine-tuning. In addition, we classify the types of questions into three types: fact, imagination, and applied questions used in the famous Habruta, and subdivide each question according to the character to derive a total of 9 question patterns. In order to verify the feasibilityof the proposed methodology, we conducted an experiment that analyzed 300 characters of actual oriental paintings. As a result of the experiment, we confirmed that the gender classification model according to our methodology shows higher accuracy than the existing model.

최근 국내외에서 활발히 추진되고 있는 전자상거래는 비즈니스의 모든 프로세스를 전자화하고 디지털 통신망에 접속을 자동화하는 정보화 혁명으로써, 전자상거래의 보편화되면서 신용카드번호, 비밀번호 등 대금결제를 위한 중요한 개인 정보가 네트워크에 노출될 수밖에 없고 해커들의 공격 유형도 다양해 질 것으로 보인다. 본 논문에서는 전자상거래의 체계의 특징, 지불 시스템, 인증 시스템의 종류, 개인정보 위협요소들의 분석을 통해 전자상거래 최적환경을 만들기 위한 전자상거래 보안 시스템을 설계하였다.

본 연구는 모바일 비즈니스(Mobile-business)에서 모바일 서비스 특성이 고객충성도와 재구매에 미치는 영향에 관하여 연구하고자 한다. 모바일 서비스를 제공하는 기업들이 성공하기 위해서 사용자의 서비스에 대한 충성도를 높일 수 있는 확실한 콘텐츠를 개발하는 것은 매우 중요하다. 모바일 비즈니스의 기존연구를 살펴보면 고객의 충성도와 재구매를 높이기 위해 구체적 어떠한 서비스 특성이 영향을 미치는 가에 대한 연구는 미진한 편이다. 따라서 본 연구는 선행연구에서 연구된 모바일 비즈니스의 특성과 인터넷 특성을 고려하여 모바일만의 서비스 특성을 제시하고, 이를 실증 분석하여 주요한 영향요인을 도출하고자 한다. 본 연구에 제시하고자 하는 모바일 특성의 3가지 유형은 모바일 정보 특성과 인터페이스 특성, 모바일 이용 특성으로 분류하고 있다. 본 연구를 수행하는 방법은 모바일 특성을 선행변수로 하고, 재구매 의도와 고객충성도를 결과변수로 하는 연구 모형을 설정하여 실증연구를 수행하였다. 모바일 사용 주계층인 10대에서 30대를 대상으로 총 226부을 연구에 사용하였다. 연구 결과 첫째, 고객충성도와 재구매 의도간에 강한 영향정도가 있었고, 둘째, 고객충성도에 영향을 미치는 요인으로는 정보 특성 요인과 인터페이스 요인 중 간결성으로 나타났으며, 셋째, 재구매 의도에 영향을 주는 요인은 정보 특성 요인 중 정확성과 최신성과 인터페이스 특성 요인으로 나타났다.

Although there is a growing body of research on organizational commitment profiles based on a person-centered approach, it is not widely applied to the commitment research conducted by Korean organizational scholars yet. Therefore, in this paper, we introduced the concept and analytical methods, such as cluster analysis and latent profile analysis (LPA), of the person-centered approach. In addition, we also performed both cluster analysis and LPA to identify types of organizational commitment profiles of Korean employees based on the combination of affective, continuance and normative commitment on the sample from a range of different fields in South Korea (n = 349). Both analyses extracted two comparable sets of 6 commitment profiles. These six profiles were then contrasted with employee turnover intention. Finally, implications for commitment theory, practices and future research issues were discussed.

In order to help the understanding of web novel users, this study was intended to quantitatively verify the user's behavioral types according to the characteristics of web novels. For this purpose, the direction of the study proceeded as follows. First, the motives of web novel users were investigated by referring to the motives of other digital content users. In addition, specific behavioral types of users were also collected. As a result, the motivation for using web novels was found to be 'interpersonal relationships and information acquisition with others', 'leisure activities', and 'escape from reality/relieve tension'. After that, the groups were classified as to whether there was a difference between groups according to the motives of use. As a result, the 'hobbies' type, a group with a particularly high motivation for using leisure activities, the 'stress relief' type, a group with very high escapism and tension relief characteristics, and a group with high interpersonal relationships and information acquisition with others The 'communication' type was classified as a 'multipurpose' type with high overall motivation characteristics. Then, in order to find out the specific characteristics between the types, personas were constructed based on the different behavior type data. Through this, the theoretical contribution of this study is meaningful in that it revealed the motives of web novel users. As a practical contribution, the persona was formed by combining the users' motives and behavioral patterns and visualized to be close to the actual representative users. These results are expected to help improve the web novel service by providing useful indicators for actual writers, platform managers, and users.

The purpose of this study is to investigate and analyze the actual conditions of consumer damage occuring in the use of clothing products. The data used for analysis included 470 cases, which were deliberated by requesting consumer disputes deliberation at the consumer consultation room of Masan YWCA at the Kyeongsangnamdo Consumer Life Center belonging to the Kyeongnam provincial office. The disputes regarding the clothing products insisted that consumers suffered damage for the period from March, 2011 to June, 2013. The data processing was carried out by SPSS 14 and the statistics techniques used went through a cross tabulation analysis and ${\chi}^2$-test. The results are as follows. The difference in the analysis result of purchase path and material as to kinds of clothing products showed a significant difference. The damage types of clothing products were classified into five types: change of color, change of style, change of surface and touch, breakage of subsidiary materials, and others. The damaged clothing products showed a difference for damage frequency according to the items of clothing products; in particular, damage frequency for change of color appeared high. The damage contents of change of color were identified as metachromatism, discoloration and yellowing, stain occurrence, and decolorization. The damage responsibility for these clothing products appeared to be various as to clothing items, but was higher at dry cleaners and manufacturers.

'증거기반 교육'은 개인적 경험이나 성공 사례, 그리고 전통적인 속설보다는 과학적 연구결과와 근거가 중심이 되는 교육이다. 증거기반 창업 교육은 기존 속설과 믿음, 단편적 성공 사례로 인해 고착된 인지 편향을 완화시켜 중립적인 시각을 견지할 수 있으며, 직관과 경험을 넘어 데이터와 연구 결과에 의해 의사결정을 하는 분석적 자질을 연마하는데 기여한다. 본 논문은 현재 국내의 증기기반 창업교육의 현주소를 명확히 파악하기 위하여 1999년부터 2021년 출판된 49권의 창업교육 대학 교재를 분석하였다. 구체적으로 모든 도서의 내용을 1)창업기초, 2)비즈니스모델, 3)마케팅계획, 4)재무계획, 5)운영계획, 6)창업유형, 7)절차 및 제도의 각 7가지 기준으로 구분하고, 각각 사례, 단순통계, 변인 통계, 선행 연구의 비중을 분석하였다. 분석결과 증거의 핵심인 선행연구의 비중은 전체 교재의 총 분량 중 11.25%를 차지하는 것으로 나타났다. 이는 Charlier(2011)의 MBA 교과목 대상으로 조사한 결과와 유사한 값이다.

The best business strategy leading to innovation and productivity can be achieved by carefully analyzing internal and external environments of a company. Many companies often require, but difficult to find a tool to determine their own internal/external environmental factors including strengths, weaknesses, opportunities and threats(SWOT). SWOT is one analytical base model that is utilized in this research to design semi-automated environmental analysis process. This study investigates on SWOT generation system that is built on existing analysis database created by experts in each field. Companies can search and choose their best expressing environmental elements that are stored in the database. This semi-automated SWOT tool is expected to contribute that companies can recognize their internal capabilities more accurately, and help consider external environment changes around them.
