A proficiency test is one of programs which Korea Research Institute of Standards and Science(KRISS), as national metrology institute, is putting in operation for the mutual recognition arrangement. The Fluid Flow Group of KRISS evaluated the measurement capability for liquid flowmeter calibrator of the national calibration and test organizations. The uncertainty of national standard system was estimated in accordance with Guide to The Expression of Uncertainty in Measurement (ISO), and the turbine flowmeter, which was used for the round-robin test as a reference flowmeter, was characterized. The round-robin tests with the turbine flowmeter package were carried out in 1995 and 1999. The test results of the organizations and those of KRISS agreed within $\pm0.2$%. It is found thus that the organizations have the traceability of the national standard for liquid flow measurement.

The evaluation of port competition could be applied to determining the selection of a calling port. A few fundemental attributes of port competition were adapted by the 'brain storming' method. The criteria used for evaluating a port's competitiveness were as follows: efficiency of port operations, competitive power of each port's industry, economic activity of the hinderland associated with each port and capability of globalization. The weight of each criterion was 30%, 40%, 20% & 10%, respectively. And the most important factors that were considered in choosing each of the above criteria were profitability, port information system, cargo volume & inducement of foreign capital. The results of this study seemed to suggest that factors which influence port competition varied according to port circumstances, such as computer and communication systems and access to the global trade within the World Trade Organization

As the population of olds increases, the number of old people with capability increases, and they actively participate to social works with interests in healthy life and leisures. Therefore the demand rises to expand social facilities to support their spare time, while there are limitation, such as land, financial state, to build such facilities. In case of Japan, a solution of such problem occurs by compounding Social facilities for Old people and local facilities in practical and finacial aspect of the selection of site and managing the facilities and social aspect of supporting oppotunities to use various facilities. Such community based complex facilities supports services depending on the health state of Old people locally residing and increases the communication between different generation. The purpose of this research is aimed to analyze programs and space organization of advanced facilities in Japan and provide basical data for planning complex facilities for old people in Korea.

In recent years, research has begun to place greater emphasis on the strategic use of IT in seeking to build firm's capability, thus innovating firm's business value. Many leading firms have been put efforts to formulate and implement IT governance (ITG) structures, processes, and mechanisms for firm's IT activities. However, recent literatures reviews found that ITG framework have been discussed independently rather than in an integrated and on convergent manner failing to provide comprehensive conceptual framework. The objective of this paper is therefore, to develop a conceptual framework that enable to conduct a comparative ITG case studies. The proposed framework, developed by one of author, has extensively applied in real case study to validate its usefulness and also aims to contribute practitioners to understand how well IT principles are formed within the organization as well as corelate with ITG objectives and ITG execution.

National Competency Standard(NCS) is a national organization that organizes the knowledge, skills, and quality required to perform duties at industrial sites by industry sector and level. As NCS was developed and adopted as part of the government's implementation of capability-oriented society, the construction industry is also fully applying NCS to the curriculum and training. This study investigated and analyzed the problems of NCS development in construction work field through prior research analysis and experts interview and derived problems such as discrepancies in classification system, lack of connectivity with curriculum, and lack of effectiveness in revising NCS in construction work field. Further research is thought to be necessary for the establishment of the development system reflecting the construction characteristics in the future and for the presentation of practical improvement directions.

This paper presents a comprehensive survey of various artificial intelligence (AI) techniques implemented in cognitive radio engine to improve cognition capability in cognitive radio networks (CRNs). AI enables systems to solve problems by emulating human biological processes such as learning, reasoning, decision making, self-adaptation, self-organization, and self-stability. The use of AI techniques is studied in applications related to the major tasks of cognitive radio including spectrum sensing, spectrum sharing, spectrum mobility, and decision making regarding dynamic spectrum access, resource allocation, parameter adaptation, and optimization problem. The aim is to provide a single source as a survey paper to help researchers better understand the various implementations of AI approaches to different cognitive radio designs, as well as to refer interested readers to the recent AI research works done in CRNs.

국내 많은 기업들이 CMMI(Capability Maturity Model Integration) 모델을 도입해서 소프트웨어 개발 프로세스를 구축 및 내재화 후 CMU(Carnegie Mellon University)의 SEI(Software Engineering Institute)로부터 인증을 받고 있지만, CMMI Maturity Level 3 이상 인증 받은 조직에서 조차도 프로젝트 지연 및 품질 문제가 자주 발생한다. 프로젝트 지연 문제는 개발 단계 이후에 대부분 발생되고 있으며, 이는 현저히 낮은 소프트웨어 개발 생산성의 영향 때문이다. 본 논문에서는 프로젝트 개발 생산성에 영향을 미치는 중요 요인을 분석하고, 이에 따른 작업의 가치를 결정하는 방법을 제시한다.

Purpose: The current research investigates the beneficial impacts of supply chain innovation and risk management on the competitive advantage of organizations, based on the resource-based theory (RBT) framework. Research Design, Data, and Methodology: 14 survey items were included in the study's questionnaire, utilizing a random sampling technique to gather data from 239 leaders and managers employed by various steel trading firms in Vietnam. In order to validate the data and examine relationships, the collected data is analyzed using structural equation modeling, confirmatory factor analysis, and reliability analysis via SPSS 22.0 and AMOS 22.0 software. A fictitious system has been suggested. Results: According to the findings, the most positive influence on competitive advantage is supply chain innovation, followed by risk management capability, having the second greatest positive influence. Conclusions: Some conclusions are drawn based on the research's findings in order to assist managers in realizing the significance and necessity of giving attention to supply chain innovation and improving risk management capabilities, both of which are essential components for achieving the competitive advantage of an organization.

Nowadays, many farmers use online management diagnosis tool developed by Rural development agency(RDA) for the purpose of self-diagnosis of their farm management. Database(DB) was created using the diagnosis results and has been used for agri-firm management consulting. However, the amount of diagnosis data in the DB has been decreasing year by year. This means that the diagnosis tool of RDA did not reach farmers' expectation. Therefore it is necessary to develop a practical consulting tool which is applicable for various types of agri-firm management. This study introduces a management diagnosis tool and consulting method based on multi-contingency organization theory and value chain model for the purpose of improving existing tools and methods. The consulting method based on multi-contingency organization theory shows the core strategy of agri-firms by two different ways such as "efficiency-oriented" direction and "effectiveness-orientated" direction. Also, this method emphasizes that the performance of firm can be achieved when subelements of firm activities follow the same direction with the orientation of core strategy. The important thing is the right firm management activity fitted to its strategic direction. Through this action, limited firm resources can be optimized. In order to make itself understand, this study shows a practical example applied by this method from actual agri-firms.
