The Ag/WC electrical contacts were prepared via powder metallurgy using 60 wt% Ag, 40 wt% WC, and small amounts of Co3O4 with varying WC particle sizes. After the fabrication of the contact materials, microstructure observations confirmed that WC-1 had an average grain size (AGS) of 0.27 μm, and WC-2 had an AGS of 0.35 μm. The Ag matrix in WC-1 formed fine grains, whereas a significantly larger and continuous growth of the Ag matrix was observed in WC-2. This indicates the different flow behaviors of liquid Ag during the sintering process owing to the different WC sizes. The electrical conductivities of WC-1 and WC-2 were 47.8% and 60.4%, respectively, and had a significant influence on the Ag matrix. In particular, WC-2 exhibited extremely high electrical conductivity owing to its large and continuous Ag-grain matrix. The yield strengths of WC-1 and WC-2 after compression tests were 349.9 MPa and 280.7 MPa, respectively. The high yield strength of WC-1 can be attributed to the Hall–Petch effect, whereas the low yield strength of WC-2 can be explained by the high fraction of high-angle boundaries (HAB) between the WC grains. Furthermore, the relationships between the microstructure, electrical/mechanical properties, and deformation mechanisms were evaluated.

Service industry can be divided largely into commercial industry, banking industry, insurance industry, advertising industry, and tourism industry. Of these, banking industry is playing an essential role as it constitutes the backbone of economy. Banking industry, which belongs to financial industry, is sensitive to external environment. In this kind of industry, internal dynamics of an organization is very important. The purpose of this research is to find out what kind of influence the relation of internal dynamics perceived by members of Nonghyup organization has on customer orientation via quality of internal service. For the purpose, we have reviewed preceding studies on variables that affect customer orientation and developed a measuring tool in a form that fits banking organizations. Internal service quality, job satisfaction, and organizational immersion which play a mediating role in the model of this research not only turned out to have a significant influence on customer orientation, they also turned out to have the strongest influence. This research has academic significance as it carried out a research with an emphasis on variables that affect customer orientation of members of Nonghyup organization. Regarding practical significance, it was intended to present useful data that can be utilized for an analysis of internal service quality management and capability of human resource management.

본 연구에서는 냉동저장에 따른 제빵용 밀가루 반죽의물리적 특성 변화를 분석하기 위하여, 냉동생지를 제조 후2주간 -20oC에서 냉동 저장하면서 신장특성, 텍스처, 부피,색상 등의 품질 특성을 측정하고 이를 냉동저장을 하지 않은 대조구와 비교하였다. Extensograph를 활용하여 냉동저장한 밀가루 반죽은 신장도와 신장저항도가 증가하였으며 R/E도 증가함을 확인하였다. 냉동생지를 이용하여 빵을제조한 경우 빵의 부피는 감소하고, 이에 따라 경도는 증가하였고 대조구와 비교하여 어두운 표면이 관찰되었다. 이러한 본 연구의 결과는 냉동 저장 반죽을 이용한 제품제조 시 냉동생지의 물리학적 특성을 파악하여 그 품질을 개선 및 보완하는데 필요한 기초 자료로 활용 될 수 있을 것으로 기대된다.

Among recent management innovation activities of companies, one of the most important competitive advantage through customer satisfaction, and to which members of the organization's service orientation is essential. The company's service orientation is closely related to the organization's culture. In this study, the organization's service-oriented culture, the internal service quality, job satisfaction and organizational commitment, and ultimately affects the employee's influence on customer orientation will look at that. Results and implications of this study can be summarized as follows. the internal service quality among the factors tangibles, assurance, empathy, job satisfaction showed a significant influence on the type of empathy and emotional commitment castle had a significant impact on. With these results, relationships with colleagues within the organization, such as work environment and job satisfaction and emotional commitment, the atmosphere is very important to know that you can affect. Therefore, the members of the company to increase job satisfaction and organizational commitment, corporate culture, business as well as collaboration with colleagues to share the emotional atmosphere of sympathy for the business environment will get improved.

수정 시뮬레이티드어닐링은 Simulated Annealing(SA)가 확률 탐색 방법을 사용하기 때문에 수렴시간이 오래 걸리는 단점를 개선한 방법이다. 따라서 본 논문에서는 RSA와 SA을 트러스구조물과 인공위성구조물의 최적화에 적용하여 서로 비교하여 보았다. 최적화 예제로 10부재 트러스, 실제 응용예제로 인공위성구조물은 위성 상단 플랫폼과 추진모듈의 최적화를 수행하였다. 인공위성구조물의 최적화에서 응력과 고유진동수, 전단응력 등을 제한조건으로 고려하여 최적화를 수행하였다. 인공위성구조물의 최적화를 수행한 결과 RSA을 이용하여 다양한 인공위성 구조물의 최적화에 적용될 수 있음을 확인하였으며, 인공위성 구조물의 최적화에서 RSA가 SA보다 수렴속도가 향상되었음을 확인하였다.
