Mahseer (Tor soro) growth performance tends to be slow, necessitating further development and intensification of cultivation. One way to develop aquaculture intensification is to manipulate cultivation containers to create optimal environmental conditions for the mahseer to grow. This study aimed to examine the body performance and growth performance of mahseer reared in different colored containers. Experimental research with completely randomized design was employed, with four colored container treatments namely treatment A (transparent), B (green), C (blue), and D (black), with four replications in each treatment. Findings indicate that different rearing media colors had significant effect on absolute length (4.68 ± 0.24 cm), absolute weight (1.58 ± 0.35 g), specific growth rate (2.17 ± 0.38%), feed conversion ratio (2.87 ± 0.04), survival rate (100 ± 0.00%), gross energy (3,816 ± 65.05 cal/g), and body proximate. Physiologically, mahseer fish bred using blue and black containers tend to be more resistant to stress.The best body performance and growth performance were observed in the blue and black colored containers.

Introduction of ICE(Integrated Collaboration Environment) has a great effect on corporate performance. In particular, it is expected that information sharing and collaboration among transaction partners will be an important factor which mediates ICE and its performance. Under such a background, this research intends to identify the influence of ICE by manufacturing industry on corporate performance through role of the parameter of information sharing and collaboration. The result of this research may be summed up as follows: ICE promotes information sharing and collaboration among enterprises, it accelerates integration of supply chain network among enterprises and cooperation. In particular, ICE has a great effect on information sharing. And information sharing has a direct effect on collaboration and performance. However, when we classify corporate performance into the "performance due to introduction", which is direct performance, and the "overall performance", which is indirect performance, the result of this research is as follows: information sharing has a great effect on the performance due to introduction, but does not have a meaningful effect on indirect performance. On the other hand, collaboration does not have any effect on the performance due to introduction, but has a meaningful effect on the overall performance, which is indirect performance. It is necessary to study and analyze additional this result in future.

This study aims to provide the results of a case study, based on the action research approach, in which an user-oriented management system for enterprise information systems operational performance is successful developed and applied. This study performs the research and summarizes the results by adopting 5-step approach of action research, i.e., diagnosing, action planning, action taking, evaluating and specifying learning. The most important lessons learned from the study include (1) operation performance measures should be established to be shared by the management and users; (2) evaluation and improvement activities should be performed continually; and (3) formula to calculate the measure should be evolved so that improvement initiatives can be identified. The results of the study are expected to provide the companies intending to develop a management system for enterprise information systems operational performance with the practical and useful information. In addition, it is expected to suggest the research results that can be utilized as a basis for future research in this area.

This paper investigates how the weights of performance measures vary depending on corporate life cycle, such as birth, growth, maturity, revival, and decline. Balanced Scorecard performance measures are employed for this investigation. Balanced Scorecard has been widely used for measuring a corporate Performance by incorporating financial and non-financial measures simultaneously. Because these performance measures are related to the compensation and promotion of employees, research of weights of performance measures would be instrumental. Questionnaires from 218 companies are analyzed. Depending on the corporate life cycle, our survey results demonstrate that the weights of the business Performance measures differ In the four Perspectives - financial. customer, Internal Process, and learning/growth. Our results can be used for enhancing the Duality of performance measurement systems.

최근 의료 서비스의 질 향상과 환자 안전에 대한 관심이 대두되면서 간호 업무수행에 대한 중요성이 증가하고 있다. 본 연구의 목적은 현재까지 수행된 간호사의 업무수행과 관련된 국내 연구들을 분석함으로써 이들 연구들의 현황 및 문제점을 조사하고 추후 연구의 발전방향을 제시하고자 시도되었다. 간호 퍼포먼스 관련 연구 33편 중 25편은 서술적 상관관계 연구였다. 간호 퍼포먼스를 측정한 도구에 있어서는 15편에서 Park (1989)의 도구 및 이를 기반으로 수정한 도구가 사용되었다. 간호 퍼포먼스에 대한 용어 사용과 정의에 있어서는 일치된 합의가 없었다. 대부분의 연구에서 간호 퍼포먼스를 리더십이나, 임파워먼트 등의 요소들에 의해 영향을 받는 결과값으로 설계하였다. 따라서 추후 연구에서는 국내 간호사의 퍼포먼스에 대한 개념적 기틀을 구축할 것을 제언하며, 간호 퍼포먼스가 의료 환경의 구조적, 과정적, 결과적 변수와는 어떠한 상호관련성을 가지는 지를 총체적으로 확인해보는 연구가 필요할 것으로 사료된다.

In this study, in order to utilize the seawater as a heat source at Gangneung city near the East Sea in Korea, an annual heating performance of a screw heat pump was simulated. For a simulation, the maximum heating capacity of heat pump was assumed at 3.5 MW. An ambient temperature at Gangneung city was calculated from the TMY2 weather data, while the seawater temperature was calculated from the regression equation based on the measurement by the National Fisheries Research and Development Institute of Korea. The heating load was assumed linearly dependent on the ambient temperature, while the maximum heating load was assumed to appear when the ambient temperature is below $-2.4^{\circ}C$, which is the temperature of TAC 2.5% for heating at Gangneung city. A heat pump performance at full-load was calculated from the regression equation, which involves refrigerant's evaporating and condensing temperatures, based on a commercial screw compressor performance map. A heating supply temperature which determines refrigerant's condensing temperature was assumed linearly dependent on the heating load. A performance degradation due to the part-load operation of heat pump was also considered. Simulation results show that an annual heating coefficient of performance ($COP_H$) of a seawater-source screw heat pump is approximately 2.8 and that it is necessary to improve part-load performance to increase an annual performance of the heat pump.

본 연구에서는 전국의 국공립 및 사립, 전문대학의 교수들 2,618명을 대상으로 교수연구업적평가와 관련하여 교수들의 인식을 파악하고자 설문조사를 수행하였다. 설문조사는 두 가지 부분에 대한 인식을 파악하기 위한 조사로 하나는 현재 각 대학에서 진행되고 있는 교수연구업적평가에 대한 인식조사이며, 다른 하나는 정량 위주의 업적평가 방식의 대안으로 여겨지는 정성적 평가 지표의 도입에 대한 인식조사이다. 설문 결과, 교수 연구업적평가에서 정량 중심 평가는 여전히 대다수의 대학에서 크게 활용되며, 계열 또는 분야에 적합하지 않은 연구업적평가가 이루어지고 있으며, 평가 기간의 확대가 필요를 요구하고, 정량 위주의 업적평가 방식은 학술 커뮤니티에 부정적인 영향을 가져오며, 연구업적평가에 대한 개선의 필요하다는 인식을 가지고 있는 것을 확인할 수 있었다. 정성적 평가 지표의 도입과 관련하여 교수들은 연구업적평가에 정성적 평가가 필요하다는 인식을 하고 있으며, 정성적 평가 도입과 관련하여 부정적인 의견 또한 존재하는 것을 확인할 수 있었다.

In order to obtain key technologies for a kW class internal humidifying proton-exchange-membrane fuel cell (PEMFC) a single cell with a large electrode area has been designed and manufactured and the performance of large area membrane/electrode assemblies (MEAs) has been evaluated by using the single cell. A small area MEA made of commercial E-TEK electrode and Nafion 117 membrane showed a performance of 0.7V, $300mA/cm^2$ whereas large area MEA made of catalyst layer on carbon support and Nafion 117 showed a lower performance. To improve the performance of large MEA direct coating of catalyst was carried out on the membrane using a screen printer.

[Purpose] Sodium bicarbonate shows ergogenic potential in physical exercise and sports activities, although there is no strong evidence which performance markers show the greatest benefit from this supplement. This study evaluated the effects of sodium bicarbonate supplementation on time trial performance and time to exhaustion in athletes and sports practitioners. [Methods] A systematic review was conducted using three databases, including 17 clinical trials. Among these clinical trials, 11 were considered eligible for the meta-analysis according to the criteria for the assessment of methodological quality using the PEDro Scale. Time to exhaustion was assessed in six studies, while time trial performance was evaluated in five studies. [Results] A significant beneficial effect of supplementation on time to exhaustion was found in a random effects model (1.48; 95% confidence interval [CI], 0.49 to 2.48). There was no significant effect of supplementation on time trial performance in a fixed effects model (slope = -0.75; 95% CI, -2.04 to 0.55) relative to a placebo group. [Conclusion] Sodium bicarbonate has the potential to improve sports performance in general, especially in terms of time to exhaustion.
