In a competitive organizational environment, members view completing tasks to perfection without mistakes as the requirement for success and good evaluation from others. However, unrealistically strong perfectionism can have negative effects on members' psychological states and organizational performance. This study focuses on evaluative concerns perfectionism, the negative aspect of perfectionism, based on positive psychology theory to explore the positive mechanism that comes into place in the process of strengthening organization members' resilience. For this purpose, we performed a moderated moderation analysis to investigate whether the moderating effect of leaders' social support (primary moderator) is moderated by their emotional intelligence (secondary moderator). To verify our research model, we conducted a two-part survey of 252 employees in various industries with a time interval to minimize the common method bias. Job rank and positive affectivity were set as control variables to identify the clear causal relationship among variables. Our findings showed that first, evaluative concerns perfectionism reduced resilience; second, leaders' social support positively moderated the relationship between evaluative concerns perfectionism and resilience; and third, the leaders' emotional intelligence positively moderated the two-way interaction between evaluative concerns perfectionism and the leaders' social support, confirming a moderated moderation. Our findings suggest the need for leaders to assume multidimensional roles to enhance the positive traits of organization members, especially in today's complex business environment. The implications of our findings are further discussed in relation to knowledge management and the development of organization members who exhibit evaluative concerns perfectionism, along with suggestions for future research.

This paper presetns an adaptive critic self-learning control system with cerebellar model articulation controller (CMAC)-based decoder integrated with the associative search element (ASE) and adatpive critic element(ACE)- based scheme. The tast of the system is to balance a pole that is hinged to a movable cart by applying forces to the cart's base. The problem is that error feedback information is limited. This problem can be sloved when some adaptive control devices are involved. The ASE incorporates prediction information for reinforrcement from a critic to produce evaluative information for the plant. The CMAC-based decoder interprets one state to a set of patways into the ASE/ACE. These signals correspond to te current state and its possible preceding action states. The CMAC's information interpolation improves the learning speed. And design inverted pendulum hardware system to show control capability with neural network.

While prior work has noted the importance of knowledge creation in gaining competitive advantages, much less is understood about why firms do not actually use what they create. Building upon institutional approaches to organization studies, we offer a new framework to explain the gap between knowledge creation and utilization. We test our framework in an empirical context of sustainable innovation and environmental technologies where ideas of environmental sustainability have recently gained public popularity and shaped how interested audiences make evaluative assessments of firms. In such a context, firms are apt to perceive the social attention toward sustainability to be a normative pressure, which causes them to create new knowledge and develop technologies consistent with the pressure. Using data from the government-initiated certification system for green technologies, our study finds that firms do not always fully implement new environmental technologies they develop in response to the certification program, the situation we refer to as knowledge decoupling. We also examine a set of conditions under which knowledge decoupling becomes more or less amplified. Taken together, our findings show how a firm's knowledge creation and utilization is shaped by its external institutional environment as well as internal learning processes.

The purpose of this study is to develop a valid and reliable instrument, applicable to high school Earth Science class experiment. In advance of developing items, I was selected 14 inquiry process skills and specified evaluative objectives for each of them to develop scales and criteria for them. I developed 28 evaluation items for 5 experiment subjects among those of high school Earth Science class. The first field trial was performed a sample of 5 high school students, and the second one using a sample of 25 high school students. The results are as follows. (1) The content validity and reliability(Cronbach $\alpha$) of the developed items were 82.7% and .86, respectively, the developed instrument in this study is considered valid and reliable. (2) The average difficulty index was .69 and the discrimination index was .30. (3) Answer sheets based on the reported results were rated 5 teachers and Inter-rater Reliabilitiy and Inter-rater Consistency were analyzed, its indices were .80 and .76, respectively. (4) The developed items show a low coefficient of .45 with TESIS, a set of paper-and-pencil test items developed by Lee, Hang-Ro(1991). That the experiment assessment is solely subject to the rater's viewpoint has been one of the major problems raised concerning the matter. This research, however, shows that a set of more specified scales and criteria for the evaluation will make it more valid, reliable and efficient.

The multifarious array of benefits to the e-Government systems research, from evaluative frameworks and conceptual models to guidelines for initiatives, adoption, and assimilation, evidences the requirement, both from the researcher's and the practitioner's standpoint, of sound theoretical foundations that can be applied directly in practice. Grounded upon structuration theory, this paper proposes a framework for e-Government systems assimilation through the structuration of its organizational factors. Upon this proposition, we map the factors of e-Government systems assimilation with the organizational meta-structures of signification, domination and legitimization. The framework is then tested for the case of one particular e-Government systems of Korean government. The juxtaposition of the theoretical position and the practical findings leads us to isolate the organizational, technological, and inter-organizational factors that shape the meta-structures for the assimilation of e-Government systems. This framework offers interesting possibilities to researchers in exploring the relationships and insights into the complex interactions that shape the relationships among government, people and technology. Thus, the paper's contribution lies on three axes: first, the furthering of a theoretical perspective of e-Government systems assimilation; second, a detailed exposition of the structuration theory and an illustration of its application to the issues of e-Government systems assimilation in the organizational context; and finally, developed framework through the isolation of a usable set of theoretically grounded factors affecting e-Government systems assimilation that can be applied in future research and practice.

본 연구는 쾌적성을 증진시킬 수 있고, 인간의 건강에 긍정적인 영향을 미칠 수 있는 음이온을 평가인자로 설정하고, 학교별 녹지특성 및 배치, 기상요소를 구분하여 음이온 발생에 효과적인 학교숲 조성모델을 제시하고, 더 나아가 도시녹지 조성에 대한 기초자료로 제공하고자 하였다. 연구결과, 음이온의 경우 식재구조에 따라 차이가 있으며, 단층구조($934ea/cm^3$) > 다층구조($794ea/cm^3$) > 잔디($553ea/cm^3$) > 나지($529ea/cm^3$)의 순으로 분석되었다. 또한 기상요소와의 상관성의 경우, 기온과 부의 상관관계인 것으로 분석되었다. 분산분석 및 사후분석 결과, 식재구조의 차이에 따른 음이온발생량은 통계적으로 차이가 있는 것으로 분석되었다. 녹지구조에 따른 음이온농도의 차이는 다층구조보다 단층구조에서 더 높은 것으로 분석되었다. 이는 다층구조에서 단층구조보다 기온이 더 높게 측정되었는데, 선행연구 고찰결과, 음이온 발생원에서 일정거리 이내에서는 기온이 높을수록 음이온 농도가 낮아지기 때문인 것으로 사료되었다. 또한 풍속이 다층구조 식재구조보다 단층구조 식재구조에서 더 높게 측정되었는데, 음이온의 확산에 있어 단층구조 식재구조가 다층구조 식재구조에 비하여 수목에 의한 바람의 차폐가 상대적으로 덜 이루어져 음이온의 발생과 확산이 더 유리할 것으로 사료되었다.
