We have studied a chip-on-board LED lighting optical system for various luminous-intensity-distribution angles of the LED. An optical system that can accept different LEDs was made to reduce the systems's weight and size as we selected the chip-on-board LED, which is easy to apply to optical systems, unlike existing package-on-board LEDs. The luminous-intensity-distribution angles were $45^{\circ}$, $60^{\circ}$, $90^{\circ}$, and $120^{\circ}$. We researched these four types of optical systems. The $45^{\circ}$ and $60^{\circ}$ units were developed into reflectors, and the $90^{\circ}$ and $120^{\circ}$ units, into lenses. We checked the performance of the designed optical system through simulation and made a mock-up. Then we made a prototype of the chip-on-board LED high bay for use with the mock-up. After measuring its performance, we tested the luminous-intensity-distribution angles and compared them with simulation data. The resulting prototype was developed considering brightness, light uniformity, age, and economics which are suitable for a factory environment.

암묵지는 전이를 통해 증식되며, 가치 또한 증대된다. 암묵지 전이는 조직의 경쟁력 향상을 위한 가장 중요한 역할을 담당하고 있다. 암묵지 전이가 매우 중요함에도 불구하고, 암묵지 전이는 활발히 이루어지지 못하고 있다. 암묵지 전이를 방해하는 장벽이 암묵지 전이를 저해하고 있기 때문이다. 암묵지 전이를 방해하는 장벽은 지식과 지식전문가에 대한 이해부족, 업무 가중 및 미흡한 보상, 신뢰부족과 지식 접착성(Knowledge Stickiness)이다. 암묵지 전이의 장벽을 극복하기 위해서는 암묵지 지식전이를 주도적으로 추진하는 대리인이 필요하다. 지식중개자는 암묵지 전이를 위한 근간이며, 효율적인 지식네트워크의 구축은 암묵지 전이를 위한 핵심성공요소이다. 그러나 지식네트워크 관련된 대부분의 연구는 네트워크의 근접성과 밀도, 중심성 등 기초지표를 활용하는 수준에 머무르고 있다. 암묵지 전이 활성화를 위한 새로운 지식중개인 진단 프레임워크가 필요하다. 따라서 사회연결망분석을 기반으로 조직관점 및 지식근로자관점의 암묵지 전이를 분석하고, 이를 기반으로 BSKT 구축안을 제시하고자 한다.

This study reviews and modifies general IS success models to find success factors of WIS(Web-based Information Systems) and to confirm the relationship between WIS success and user's satisfaction of web use. A WISSM(Web-based Information Success Model extended to include EQ(E-Quality) is developed to anticipate user's intention to use Web-based Agricultural Information System and fit into the survey data from 252 WIS users of RDA(Rural Development Administration). PLS is applied to estimate a structural model based on EQ-WISSM to test hypotheses including 1) users reach a high level of intention to use Web-based Information Systems when they feel a high level of interactivity among an 'E-Quality', 'Decision Making Support Satisfaction' and 'Task Support Satisfaction', and E-Quality boosts intention to use Web-based Information Systems. The results show high path coefficients and $R^2$ values and find followings; First, the EQ-WISSM explains the user's intention to use WAIS quite well. Second, E-Quality can be used well in web-based IS environment to predict IS Success. Finally, this research finds the importance of 'Task Support Satisfaction' as a mediator between 'Decision Making Support Satisfaction', 'E-Quality' and 'Intention to Use'.

Narratives arouse diverse and rich affective responses to recipients, and this is one of the reasons why narratives are universal and popular. Computational studies on narratives have established a formal model or system of the affective response based on the theory in psychology or media research, and have analyzed or generated a narrative that can evoke a specific affective response. In this paper, we propose a new computational model that can detect the affective response expected to appear in the narrative based on the narrative agent's knowledge. First, we designed a narrative representation model that can elaborately express the event structure and the agent's knowledge as well. Additionally, an analysis method was proposed to detect the three affective responses and the related situational information. Then, we validated the model through a case study about an actual movie narrative. Through the case study, we confirmed that the model captures the affective responses of the audience. The proposed model can be effectively used for the narrative analysis and the creation that must consider the affective responses of the recipient.

In this research, the automatic synthesis of knowledge models is proposed. which are the basis of the methods using qualitative models adapted widely in fault diagnosis and hazard evaluation of chemical processes. To provide an easy and fast way to construct accurate causal model of the target process, the Role-Behavior modeling method is developed to represent the knowledge of modularized process units. In this modeling method, Fault-Behavior model and Structure-Role model present the relationship of the internal behaviors and faults in the process units and the relationship between process units respectively. Through the multiple modeling techniques, the knowledge is separated into what is independent of process and dependent on process to provide the extensibility and portability in model building, and possibility in the automatic synthesis. By taking advantage of the Role-Behavior Model, an algorithm is proposed to synthesize the plant-wide causal model, Fault-Causality Graph (FCG) from specific Fault-Behavior models of the each unit process, which are derived from generic Fault-Behavior models and Structure-Role model. To validate the proposed modeling method and algorithm, a system for building FCG model is developed on G2, an expert system development tool. Case study such as CSTR with recycle using the developed system showed that the proposed method and algorithm were remarkably effective in synthesizing the causal knowledge models for diagnosis of chemical processes.

Purpose Since COVID-19, the demand for online class platforms has increased. However, those platforms have not been clearly defined, and related research is also limited. In the context of the knowledge marketplace (KMs), this study examined the effects of class information and trust in creators on class preferences from the perspective of consumption value theory. Design/methodology/approach By establishing a web crawler through Python, this study collected 1,174 class data in Korea's leading knowledge marketplace, Class 101, focusing on diverse class-related information and the number of Instagram followers for individual class creators. Based on class information, this research analyzed the effects of consumers' utilitarian value, social value, and hedonic value on class preference. In addition, this study examined whether consumers' trust in creators moderates the relationship between class information and class preference. Findings According to analysis results, it was found that the higher the consumers' consumption value for each class on KMs, the more positive their preference for the class. Also, it was confirmed that consumers' trust in creators moderates the relationship between class information and class preference.

이 연구는 최근, 대학도서관 뿐만 아니라 특수ㆍ전문도서관 등에서도 자주 나타나고 있는 PDL의 등장 배경과 지식기반사회에서 PDL의 개념이 어떻게 형성되었는가를 살펴보았다. 또한, 이와 관련한 사례들을 함께 살펴봄으로써 현행 PDL 개념의 확장에 관한 발전적 제안을 발견하게 되었는데, 이것은 향후, 이용자 중심의 PDL모형을 개발하는데 있어 중요한 기초 자료가 될 것이라 생각한다. 이 연구에서 밝혀진 PDL모형 개발시 유의점은 다음과 같다. \circled1 개인화가 발생하게 된 사회 환경의 변화에 그 의미를 찾아야 한다. \circled2 제공되어지는 콘텐츠는 제한을 두지 않아야 한다. \circled3 개인의 요구조건을 충분히 만족할 수 있는 시스템이어야 한다 \circled4 시스템구현 방법은 공개적이어야 하며, 계속적인 지원이 가능하도록 오픈소스 개념으로 개발되어져야 한다.

Innovation becomes norm rather than exception in today's business, and accordingly firms are working on how to make their employees to work smarter using information systems and technologies. Smart work demands virtual collaboration and cooperation among team members in different places and different time. Sharing of knowledge among team members in these innovative activities are critical in every sense for the successful performance. This study explores the antecedents of knowledge sharing among team members in team-based innovation activities. Five factors (pleasure of knowledge sharing, self-efficacy, management support, rewards, and system usage) are identified through extant review of literature and an instrument is adopted and validated from previous studies. The instrument is adminitered against 138 individuals in and across 54 teams in a telecommunication firm. Except self efficacy, all the paths in the proposed research model is confirmed with different levels of relational coefficients towards the levels of knowledge sharing and innovation activities in teams. Surprisingly, findings indicate that intrinsic pleasure of sharing is most critical than management support, organizational rewards or system usage. This study fills the research gap in team management. Findings provide important implications for managing teams in coming virtual and smart environment.
