본 논문의 목적은 설계 변경된 세척기의 유한요소해석에 있으며 세척 성능을 향상시킨 세척기 개발을 위하여 기존 세척기의 구조를 변경하여 설계하였다. 설계 시 프로그램은 CATIA V5를 사용하였으며 유한요소해석에 필요한 모델링 또한 CATIA V5를 사용하였다. 모델링된 세척기에 대하여 3차원 유한요소해석 프로그램인 ANSYS를 사용하여 해석을 수행하였으며 안정성을 검증하기 위하여 내부압력의 변화에 따른 유체의 흐름을 구하였다. 이러한 해석결과는 새로운 모델의 세척기를 개발하는데 활용되었다.

본 논문에서는 시스템 파라미터의 변동이나 모델의 불확실성 및 외부 외란 등에 강인한 외란 관측기에 기초로 한 강인 제어기의 설계를 제안한다. 제어기는 두 개 루프의 구조를 갖는 모델기반 보상기와 궤환 제어기 구조로 구성되어 있다. 내부 루프 보상기는 내외부의 외란을 제거하고, 외부 루프 궤환 제어기는 주어진 사양을 만족하도록 하는 역할을 수행한다. 결과적으로, 제안한 강인 제어기를 이용함으로써 외란에 대해 시스템을 안정화 시킬 수 있으며, 제어 성능을 향상시킬 수 있음을 보인다.

This paper covers a plan to build supply chain cooperation systems among stream of the textile industry to strengthen international competitiveness. To obtain the study objective, it has been reviewed the theoretical rationale relating to organizational cooperation model and discussion and performed the case study that analyzed stream group and participated firms to the textile stream policy project. The analyzed stream cooperative types that measured configuration of cooperative degree and productive type are new market creation, technology improvement, relation maintenance, and relation cease. Two types - new market creation and technology improvement - have significant effect of the textile stream cooperation. Key successful factors of these two effective types are the external intervention of specialized consulting organization and build internal coordination and integrated mechanism to the cooperative stream group and participated firms.

The purposes of this paper is to draw a conclusion on the impact of the characteristics of economic cooperation between china and south korea on customer value and enterprise performance in the korean electronics industry. In this paper, product reliability and product innovation are especially used as analytical factors, and this paper used a survey of 293 internal employees working in the electronics industry for analyze, and structural equation model(SEM) was used to analyze the data. The results of the research analysis are summarized as follows. First, it was found that the characteristic of economic cooperation in the research model has a significant effect on the product reliability. Second, it was found that the characteristics of economic cooperation have a significant effect on the products innovation. Third, the products reliability has a significant impact on customer value, while the products innovation has not affected customer value. Finally, it was found that the customer value of the korean electronics industry also has a significant impact on the Enterprise performance. As a good development alternative to this research, there is the ultimate goal of hoping that corporate managers will help to create new good values. To this end, we hope it will be helpful as we have made necessary suggestions to establish the desired direction of the Korean electronics industry operator.

As a suitable volute configuration in the range of low specific speed, circular casing is suggested in this study. The internal flows in a centrifugal pump with the circular and spiral casings are measured by PIV and analyzed by CFD. The results show that the head and efficiency of the pump by a circular casing of very small radius are almost same as those by the spiral casing. Even at the best efficiency point, the internal flow of the pump by circular casing is asymmetric, and vortex and strong secondary flow occurs in the impeller passage. The radial velocity becomes higher remarkably only near the region of the discharge throat. The flow in the impeller outlet is strongly controlled by the circular casing because the velocity distribution almost does not affected by the position of the impeller blades.

This review addresses the escalating challenge posed by antibiotic resistance, highlighting its profound impact on global public health, including increased mortality rates and healthcare expenditures. The review focuses on the need to adopt the One Health approach to effectively manage antibiotic usage across human, animal, and environmental domains. Antimicrobial stewardship programs (ASPs) are considered as comprehensive strategies that encompass both core and supplementary initiatives aimed at enhancing prudent antibiotic use. The 2021 "Guidelines on Implementing ASP in Korea" introduced such strategies, with a strong emphasis on fostering multidisciplinary and collaborative efforts. Furthermore, the "Core Elements for Implementing ASPs in Korean General Hospitals," established in 2022, provide a structured framework for ASPs, delineating leadership responsibilities, the composition of interdisciplinary ASP teams, a range of interventions, and continuous monitoring and reporting mechanisms. In addition, this review examines patient-centric campaigns such as "Speak Up, Get Smart" and emphasizes the pivotal role of a multidisciplinary approach and international cooperation in addressing the multifaceted challenges associated with antibiotic resistance.

Purpose: The purpose of this study is to examine under what conditions suggestion programs conducted by organizations actually increase individual perception of their work effectiveness. Specifically, this study looks into the effects of cooperation perception and relational demography of employee on work effectiveness of suggestion programs. It does this by focusing on the interaction effect of organizational commitment. Research design, data and methodology: Data was collected from 1,872 participants who took part in the suggestion program of HCCP 6th DATA. This data was subjected to multiple regression analysis. Results: a) higher employee cooperation perception enhances work effectiveness of suggestion program, but relational difference of knowledge diversity between team members has no effect on work efficiency; b) Positive effect of cooperation perception, and difference in education level on work effectiveness become greater as commitment increases. However, organizational commitment decreases the positive effect of difference in organizational tenure on work effectiveness by suggestion program. Conclusion: The results point to the importance of broadening the current conceptual models of employee work effectiveness of suggestion program to include relational demography, as well as the utility of conducting additional cross-level research on suggestion programs.
