  • A battery of neuropharmacological experiments showed the hot water extract of Ocimum sanctum Linn. (Labiateae) had a depressant effect on the central nervous system (CNS), but the aqueous extract showed no effect on it. The hot water extract reduced the spontaneous locomotor activity, exploratory head dipping, propulsive locomotion and exploratory ambulation as well as prolonged the pentobarbital induced sleeping time. The depressant effect starts from 60 minutes after the drug administration and continued to 180 minutes. The drug may exert central depressant effect by interfering with the function of the cortex.

  • Fricated nuclei in Nuosu Yi were found to be more correctly described as fricated vowels, rather than syllabic fricatives due to the presence of clear formant structures typical of front vowels. In this exploratory study, two types of fricated nuclei were examined: retroflex "yr" and non-retroflex "y". The retroflex nucleus "yr" had higher F1 and lower F3 than non-retroflex "y", indicating a lower tongue height. On the other hand, F2 was found to correlate not with nucleus retroflexion, but instead with onset consonant retroflexion: F2 was higher following retroflex onsets, in both vowels. This effect was persistent through the entire vowel, suggesting a phonological effect, rather than a coarticulatory one. Interpretation of the F2 results require accompanying articulatory data since the usual coupling of F2 and tongue backness does not always hold for retroflex vowels. Examining the articulation of the fricated nuclei in Nuosu Yi is a direction for future research.

  • Studies on housing concept currently activated by environmental psychology are in its early stage of developement. The trends can be characterized as case oriented, phenomenological, and exploratory. The purpose of this research was to explore empirically the housing concept from residents living in multi family housing complex through their verbal expressions. Subjects were 63 housewives of middle class households in Junggae area. Interview technique with open questions about housing concept and images was used. The responses were analyzed using content analysis in which episode was the analysis unit. Relaxation appeared the most important aspect of housing concept This seemed to imply the need for escaping from the modern city life with too much stimulus or stress. Answers on specific images considered desirable to keep and continue from past traditional housing to future housing showed their strong need for natural green environment such as garden and park. This supported the concept of relaxation as a major function of modern housing and showed a specific alternative mean to satisfy the relaxation concept.

  • This paper examines the evolution issues of regional tourism resources in complicated and networked industry the perspective of co-evolution types and dualism. Regional tourism structure has been changing more and faster according to various attractions and internal and external environment; natural resources, facilities, festivals and events, drama and movies, and public resources, etc. This paper approaches Olikowski's dualism perspective as a theoretical view about the alliance network between region's attractions and tourism industry in Korea. Exploratory analysis was explained the dualism cases performed on the matrix between resource characteristics and alliance complexity on human resources based on regional tourism industry.

  • In recent years, academic scholars and practitioners have given increasing attention to the importance of strategic performance measurement systems including both financial and non-financial performance metrics. The Balanced Scorecard (BSC) is known as integrated performance management framework that helps an enterprise to translate strategic objectives into relevant performance within an organization. While the current literatures and management articles offer BSC design and implementation. there are few reports of detailed validation of using the rationalized sets of CSF (Critical Success Factors) and KPI (Key Performance Indicators) for the Korean construction industry. This paper first propose the perceived sets of CSF/KPI using current literatures and validate with a major construction company's executives and senior managers in Korea. The paper then examines whether the perceived sets of CSF/KPI have co-relationships with the firm performances. The results of the research contribute in heightening of competitiveness of the Korean construction companies in strategic and performance management.

  • Purpose The purpose of this paper is to conduct exploratory comparative research on the determinants of successful crowdfunding projects, focusing on multiple crowdfunding platforms in Korea, U.S., and Japan. Design/methodology/approach This study collected data from three representative crowdfunding platforms: Wadiz (Korea), Kickstarter (U.S.), and Readyfor (Japan). Based on 1,906 crowdfunding projects from Wadiz, 3,864 projects from Kickstarter, and 3,060 projects from Readyfor, multiple regression models were applied. Findings Focusing on the crowdfunding projects which have overly achieved goal amount, the analysis results show that the number of comments, the number of Facebook likes and the number of backers have an positive impact on the performance of crowdfunding projects, while target amount has a negative impact. Comparatively, word counts of project description have an impact on funding performance in U.S. and Japan, while the number of images in project description affects funding performance in Korea and U.S. Meanwhile, video clips in project description has little impact on crowdfunding performance in all of the three funding platforms.

  • 미국과 중국의 기술패권 전쟁이 전개되고 연구개발의 중요성이 증가함에 따라 세계 각국은 연구개발 투자를 증대하고 있다. 우리나라는 정부 및 기업의 연구개발 투자 규모가 매년 꾸준하게 증가하였으며, 창조형 기술개발의 방향으로 전환되며 다양한 분야에서 첨단 기술이 개발되고 있다. 하지만 많은 예산과 시간, 노력이 투입된 국내의 첨단 핵심 기술이 해외로 불법 유출되는 사례 또한 꾸준히 증가하고 있다. 연구보안은 이처럼 연구환경에 존재하는 보호대상을 유출 및 탈취 등의 위험요소로부터 안전하게 보호하기 위한 활동으로, 우리나라뿐만 아니라 미국 등 각국에서 연구보안을 위한 법령 및 제도를 정비하고 있다. 본 논문에서는 연구보안제도의 개선을 위해, 전 세계 연구개발비 1위를 차지하고 있으며 연구보안정책 및 법령의 정비를 위한 논의가 활발하게 이루어지고 미국의 연구보안 사례를 중점으로 우리나라의 연구보안 정책방향을 도출하고자 한다.

  • 이 논문에서는 기존 정보검색모델에서의 문제점을 살펴보고 그 대안을 제시하고 있다. 정보환경의 변화에 따라 '개념'중심의 새로운 정보조직인 온톨로지와 소셜태깅은 탐험적 발견행위를 가능하게 해줄 수 있다. 이들을 통해 어느 한 이용자의 머릿속에 있는 생각을 인터넷상의 수많은 사람의 머릿속에 있는 생각을 연결해주고 있다. 이러한 상호작용을 통한 연결고리를 통해서 이젠 이용자들이 탐험적으로, 적극적으로 정보를 찾아 나서고 있다. 이에 본 연구의 목적은 질적인 연구방법론으로 온톨로지와 소셜태깅에서 제공되는 수많은 탐색촉진제의 존재를 밝힌 후, 하나의 탐험적 발견행위 모델을 만들어내는 것이다. 그 결과는 먼저 3개의 상위그룹이 형성되었다. 첫째, 브라우징 및 모니터링으로 어떤 대상을 인지 및 집중하는 단계, 둘째, 의미부여로 적극적인 참여 및 공유하는 단계이며 셋째는 더 적극적으로 생각을 확장시켜나가면서 스스로 사회적 학습을 하는 단계였다. 제일 첫 그룹에는 정보요구인지, 소셜공간에서 도움 필요성인지, 도움을 받을 수 있는 자료 발견, 일단 멈춤, 그 대상에 집중등의 단계가 있었다. 두 번째 그룹에는 적극적 의미형성, 소셜 북마킹 및 태깅, 소셜 네트워크에서 나눔, 처음 정보요구를 더 구체화하는 단계가 있었다. 세 번째는, 발견적인 소셜학습, 우연한 정보 발견, 창조적 생각을 유발, 문제 해결 능력향상 등의 총 13단계를 발견하게 되었다. 이 모델은 이용자들이 탐험적 발견행위를 할 수 있는 능력을 향상하게 시키는 정보시스템 디자인에 공헌할 수 있을 것이다.
