This study empirically investigated the effects of knowledge management(KM) strategic alignment on the KM activities as well as the product and process innovation of manufacturing firms. Based on the framework, which employs the usage levels of target costing systems(TCS) and information technology(IT) infrastructure, four types of KM strategies were identified and proposed：mixed, explorative, exploitative and negative strategies. In this research, these four types of KM strategies were empirically validated. According to the results of this study, it was found that when a explorative KM strategy is aligned with a low-cost strategy, KM activities are activated and the degree of a process innovation is increased. It was observed that in the case of the alignment between a differentiation strategy and a exploitative KM strategy, both KM activities and the level of a product innovation are enhanced. The results also demonstrated that for the enhancement of both a process and a product innovation through the activation of KM activities, a mixed KM strategy must be aligned with a composite business strategy, which focuses on a low-cost as well as a differentiation strategies. Accordingly, it is concluded that the KM activities and the levels of the product and process innovation can be activated or improved with the alignment of the KM strategies and business strategies.

This research investigated students' interaction in the environment with dynamic geometry software such as Cabri II, and GSP in order to understand and analyze why computer environment is a richer interaction field for developing children's explorative ability than other traditional paper-and-pencil environments. This research focused on 5th graders' interaction with topics of transformational geometry and similar figure and analyzed children's learning process and their interview results gotten through audio and video recording. Computer exploration with a dynamic software seems to be very helpful for elementary students to learn geometry. However, the effectiveness of the computer should be discussed with respected to its methodological validity of teachers to guide students' explorative activities with a dynamic software.

The results of recent work on the dye-sensitized photooxygenation of sulfides is discussed. In the case of dialkyl sulfides, the weakly bonded adduct initially formed with singlet oxygen (the persulfoxide) decays unproductively unless protonation by an acid (an alcohol or a carboxylic acid) facilitates its conversion to the sulfoxide. The effect is proportional to the strength of the acid (eg., less than 0.1 % chloroacetic acid in benzene is sufficient for maximal efficiency) and corresponds to general acid catalysis, suggesting that protonation of the persulfoxide occurs. On the other hand, with sulfides possessing an activated hydrogen in ${\alpha}$ position (eg., benzyl and allyl sulfides), hydrogen transfer becomes an efficient process in aprotic media and yields a S-hydroperoxysulfoniumm ylide, possibly arising from a conformation of the persulfoxide that is different from the one protonated in the presence of acids. Calculations on some substituted sulfides support this hypothesis. This process, which leads to C-S bond fragmentation with formation of an aldehyde, may be viewed as a general method for the preparation of aryl and heteroaryl aldehydes. In this effort, mechanistic studies offered new hints on the structure of the intermediate persulfoxide.

The study aims to investigate the relationship between innovation activities and business process performance in higher education institution (hereinafter referred to as "HEI") context. The data was collected using a survey and later analyzed through Partial Least Squares Structural Equation Modelling (PLSSEM) and SmartPLS software. A total of 50 questionnaires were submitted from respondents representing vocational study program management located in Makassar, Indonesia. The findings show that two hypotheses discussed in this study fit the empirical data. Specifically, the results show that there is a positive relationship between innovation activities and business process performance, involving two types of innovation activities, which are exploration activities and exploitation activities, within HEIs. Explorative activity is firmly related to exploitative activity, which furthermore links to business process performance within the HEIs observed. The results confirm that exploration activity can stimulate and lead the HEIs management to generate exploitation activity. For instance, capabilities to absorb knowledge from the external institution may lead this institution to generate advanced academic processes, as well as more efficient and effective managerial processes. The study also signifies ambidexterity capacity, suggesting that it may lead HEIs management to formulate proper strategies in achieving better performance and gaining competitive advantage.

소규모 신생 기업들이 대기업으로 성장하면서, 성장의 발판이 되었던 기업 내 절차와 규범들이 조직을 오히려 관료화하고 구성원들의 혁신과 창의적 발상을 저해함으로써 결과적으로 기업의 경쟁우위를 약화시키는 주요한 요인으로 작용하고 있다. 기업들은 사내 기업가정신(Corporate Entrepreneurship)을 통해서 이런 문제점들을 극복하고 혁신과 창의적 발상을 지속시켜 냉혹한 경쟁 상황을 효과적으로 대응하려고 노력해 왔다. 최근 선도 기업들을 중심으로 사내 벤처 프로그램을 Seed조직으로 하여 사내 기업가정신 강화를 시도하고 있다. 주요 특성 강화를 통해서 기업가정신을 확산시키고 있는 삼성전자의 사내 벤처 프로그램인 C-Lab 사례를 심층 분석하여 사내 기업가정신 제고측면에서 1) Seed조직이 안착하기 위해서 기업이 조성해야 할 환경적 특성이 무엇인지 2) 사내 기업가정신과 관련한 어떤 주요 특성들이 Seed조직을 통해서 강화되어야 하는지 3) 주요 특성 강화를 통해 어떠한 성과가 이루어 질 수 있는지 4) 주요 특성들이 어떻게 기업 전체로 전파되는지 등을 조명하였다. 이를 기반으로 사내 기업가정신 강화 절차를 제시하였다. Seed조직의 운영이나 전파 방식에 있어서는 기업의 강점과 약점에 따라 서로 다른 접근 방식이 필요하기 때문에 사내 기업가정신 강화 절차에는 반드시 '기업 내부 역량 평가' 단계가 포함되어야 한다. 일반화된 절차와 C-Lab의 사례를 참고하여 각 기업은 자신에 맞게 절차를 구체화하여 사용함으로써 사내 기업가정신을 강화시킬 수 있을 것으로 본다.

We conducted an explorative study about the types of APEC government's policies for SME(Small and Medium Enterprise) informatization. Informatization means the process whereby information and communication technologies shape cultural and civic discourse. By using Qualitative study methods such as interviews and case studies, we identified the influential factors for the effectiveness of government policies on SME's informatization. Based on the implementation levels of these factors, we also developed the typology of government policies for SME informatization. Our conclusion ends up with the suggestion of a contingency approach for SME informatization of underdeveloped and developing countries.

This study focuses on the mediating role of creativity on the knowledge management process. To confirm focal hypotheses, we conducted survey on 538 employees of foreign subsidiaries of global enterprises. Main findings are: first, creativity turned out to positively mediate the effect of knowledge transfer on the firm's performance; second, the mediating role of creativity differs depending on the domain of acquiring knowledge such as exploitation and exploration. This research found that the influence of exploitative knowledge on knowledge creation and innovative performance was stronger. As such, among tension view and foundational view, which are two competing views on the relationship between knowledge and creativity, the latter is more soundly supported.

Organizational learning of construction team has been long addressed in the literatures, but the mechanism of learning and the influence of leader in the team still remain vague. This paper presents a computational model (OLT) depicting the mechanism and the influence of leader in a systemic way. The OLT model is a multi-agent system based on some eloquent propositions proposed in previous researches. The proposed model is preliminarily validated by some toy-problem simulations. In the OLT model, the leader is assigned as a project manager. The results show that a proper leader can effectively improve the learning process and the result-in performance, in which the team learning is mainly affected by both the leader and the majority in a team. Based on our findings, two propositions are concluded accordingly: (1) Learning of a team would be enhanced if a proper leader is assigned; (2) The effectiveness of learning would increase in a team, in which the members retain explorative attitudes.
