In order to develop a process for manufacturing a composite structure of an intermetallic compound foam and a hollow material, the firing and pore form of the Al-Ni precursor in a steel pipe are investigated. When the Al-Ni precursor is foamed in a hollow pipe, if the temperature distribution inside the precursor is uneven, the pore shape distribution becomes uneven. In free foaming, no anisotropy is observed in the foaming direction and the pore shape is isotropic. However, in the hollow pipe, the pipe expands in the pipe axis direction and fills the pipe. The interfacial adhesion between Al3Ni foam and steel pipe is excellent, and interfacial pore and reaction layer are not observed by SEM. In free foaming, the porosity is 90 %, but it decreases to about 80 % in the foam in the pipe. In the pipe foaming, most of the pore shape appears elongated in the pipe direction in the vicinity of the pipe, and this tendency is more remarkable when the inside pipe diameter is small. It can be seen that the pore size of the foam sample in the pipe is larger than that of free foam, because coarse pores remain after solidification of the foam because the shape of the foam is supported by the pipe. The vertical/horizontal length ratio expands along the pipe axis direction by foaming in the pipe, and therefore circularity is reduced.

본 연구는 상사의 성과코칭이 지식공유행동에 미치는 영향을 밝히고자 하였다. 그 과정에서 ‘개인이 대상을 자신의 것처럼 느끼는 상태’로 정의되는 심리적 주인의식을 향상적 주인의식과 방어적 주인의식 으로 구분하였으며, 그중에서 긍정적인 향상적 주인의식의 매개효과를 검증하였다. 또한, 방어적 주인의 식이 향상적 주인의식의 영향을 조절하는 효과를 검증하였다. 본 연구를 수행하기 위해 국내 서울 및 경기 지역의 직장인 260명을 대상으로 설문을 수집하였다. 수집한 자료를 바탕으로 위계적 다중회귀분석을 진행한 결과, 상사의 성과코칭이 지식공유행동에 정적인 영향을 미치는 것으로 나타났다. 또한, 그 관계를 향상적 주인의식이 완전매개한다는 것을 확인하였으며, 향상적 주인의식과 지식공유행동의 관계에서 방어적 주인의식이 유의미하게 조절하는 것으로 나타났다. 이러한 연구결과를 바탕으로 본 연구의 학문적 의의와 실무적 의의를 논의하고, 제한점과 향후 연구과제에 대해 제시하였다.

Stakeholder management in construction projects is an important factor in project performance creation. The purpose of this study is to verify the effect of the recognition of the importance of the quality influence factors among the stakeholders of the construction project on the perceived quality and the project performance. The impact of the project management methodology on the project performance has been actively researched, but there is little research result on the project stakeholders. The projects to be researched are apartments and buildings that have been completed within the last five years of domestic large construction company. The method of survey is to measure the consensus of the importance of the quality influential factors among the three parties such as the ordering party, the design supervisor and the constructor, and confirm whether the agreement affects the quality of the actual project. Finally, the research model was verified by surveying the satisfaction of the client on the final product. The results are as follow. The degree of agreement on the importance of quality influential factors among stakeholders has a significant effect on perceived quality. In the relationship between perceived quality of influence factors, organizational (support) quality influenced technological quality and managerial quality, and technological quality and managerial quality also have significant influence on resource quality. The results of analysis showed that perceived quality of resources strongly influenced project performance. The remaining three experienced qualities also significantly affect project performance.

Domestic SMEs play a key role in production and employment, accounting for 98.9% of total enterprises, 74.4% of employment, 50.8% of production, and 49.0% of value added (as of 2016). However, they are faced with difficulties of survival because of continuous decrease in profitability, shortage of funds and manpower, insufficient accumulation of technology, minimum wage increase, and 52-hour workweek. In order for SMEs to continue to develop in such a difficult environment, we must constantly innovate our organization by making full use of our knowledge, information, experience and ability. To do this, CEO (management) leadership is very important to ensure that the best people are focused on the organizational innovation and management performance without moving the company. In this study, we wanted to establish empirically how the newly emerging compassionate rationalism leadership of SMEs business managers affected the innovation activities and management performance of companies. Research has shown that management’s compassionate rationalism leadership has a positive and significant causal relationship with the innovation activities and management performance of the enterprise. Therefore, SMEs managers need to learn the bottom eight strategic factors of compassionate rationalism leadership and use them strategically to make efforts to create positive emotions for the organization so that members can be immersed in innovative activities and management performance creation.

As the technological gap amongst manufacturers decreases, the life cycle of products has shortened, and competition accelerates due to the development of technology, incumbent manufacturing companies face growth limitations. In order to overcome such business issues, manufacturing companies are increasingly interested in changes in business models and innovations, especially in the direction of providing services where they can maintain the competitive advantage of their products. In such context, this empirical study examines managerial leadership, differentiation strategies, and products and services pricing as ‘servitization factors’, which can be driving forces for moving into a new era of growth for Korean SMEs, focusing on the mediating effects of servitization competency. The results are as follows : First, it was confirmed that executive leadership, differentiation strategy, and information & communication technology capability have a direct effect on service sales. Second, the process competency, partnership competency, and ICT competency, which are presented as the service competence of SMEs, were found to play an important role in inducing service sales in managerial leadership, differentiation strategy, product and services pricing. It also emphasized the role of the public policy such as helping to foster SMEs as key partners in the expansion of social facilities and establishing platforms through ICT and data utilization for the convergence of manufacturing services.
