The aim of this study is to propose the design suitable for sustainability evaluation model of the mobile industry considering system process (SEP). Although a quantitative evaluation was conducted on the link between the national sustainability report and the mobile industry, it was confirmed that it was difficult to identify stakeholders. So it is necessary to develop the design process suitable for the more operator-specific interfaces. The Human System Integration (HSI) methodology was proposed through linkage with work domain analysis. Agile methodology and Resilience engineering methodology were added for sustainable model design. The proposed sustainability system evaluation model is applied so that it can be easily used in all industries.

The purpose of this study is to develop an engineer competency model using Analytical Hierarchy Process (AHP) to improve the national technical qualification system. Korea has managed technical human resources at the government level through the operation of a national technical qualification system that certifies engineers with national certificates or technical grades by laws. However, there have been increasing concerns that the government system is separated from global standards and does not reflect an engineer's comprehensive capabilities. For these reasons, the new architecture of the system has been continuously discussed and becomes a major policy issue of the Korean government. For the development of the engineer competency model, domestic and global models were separately structured using 554 valid questionnaires with a consistency ratio (CR) of 0.1 or less. The relative importance of engineer competency factors in a domestic model was career (0.383), qualification (0.253), academic degree (0.195), and job training (0.169) whereas the order in the global model was career (0.308), global ability (0.237), job training (0.175), domestic qualification (0.147), and academic degree (0.134). The results of AHP analysis indicated that the evaluation factors and methods recognized by engineers were different from a current government model focusing on domestic qualifications. There was also perceptual difference in the importance of engineer evaluation factors between groups depending on the type of organizations and markets. This means that it is necessary to reflect the characteristics of organizations and markets when evaluating engineer competency. Based on AHP analysis and literature reviews, this paper discussed how to develop a new engineer competency index (ECI) and presented two effective index models verified by simulation test using 59,721 engineers' information. Lastly, the paper discussed major findings of our empirical research and proposed policy alternatives for the improvement of a national engineer qualification system. The paper contributes to the management of technical human resources since it provides quantitative competency models that are objectively developed by reflecting market recognition and can be effectively used by the policy makers or firms.

The connection system of steel pile and RC footing is an important structure, because the total load of upper construction should be transferred through this joint construction of different two materials-steel and RC-with strongly changed section area. Although many connection systems have been developed, their structural and economical efficiency and workability are often insufficient. Therefore, a new connecting system was developed to improve the problems of current systems. The divided arc plate could improve the workability and economical efficiency, structural efficiency could be reached by welding construction. The main purpose of the research is to evaluate the structural behavior of the new designed connection system through experiments and numerical analysis.

This paper discusses the potential to upgrade the Thai innovation system by university-industry linkages. Our results are structured into three parts. First, the identification of potentials for university-industry linkages (UIL) within the Thai innovation system shows that the re is a wide gap between absorptive capacities of private companies and knowledge production of universities. Second, we present survey results for individual departments at Thai universities showing that UIL are mostly limited to consulting and technical services, hampered by mutual distrust, and maintained to receive an extra personal income. Third, case studies on four typical modes of UIL allow us to discuss various ways to upgrade the Thai IS by UIL in future.

In recent years, the specialized construction industry has undergone major construction and major industries, and without considering the technical expertise of construction works, the construction industry is promoting the integration and establishment of specialized construction industries according to convenience and abolition of their own industries. As the reorganization plan causes confusion in the production structure and lacks persuasive power by aiming only for industry simplification, it is judged to be desirable to review it according to the detailed characteristics of the specialized construction industry. In this study, -to review the reorganization of a rational classification system that considers the specific nature of the specialization of specialized construction projects, the classification of construction works, major work contents and characteristics, technical expertise, and problems of largescale industry in the case of painting construction and landscaping construction was analyzed. Based on this, aspects to be considered when reorganizing the current professional construction industry classification system are identified and reasonable improvement plans for each industry are suggested.

Technical efficiency of semiforcing watermelon growers is 0.8248 on average, and distributed between 0.6744 and 0.9268. The result showed that semiforcing watermelon growers had by 18% of technical inefficiency and could be assumed that increasing technical efficiency could induce watermelon production more increase. Consequently, if growers' technical efficiency were improved while other environments were constant, watermelon production could be increased. Following the results from the inefficiency effect model, all assumption coefficient such as growers age etc, are significant at 10% level. Estimate of dispersion parameter ${\gamma}$ is 0.89, which confirms those differences between practical output and frontier output were derived from the technical efficiencies among growers. Differences of production system between high and low level growers in production efficiency were showed at side altitude, ventilation and heat-retaining in section of facilities and automation, soil test and calcium application in section of environment management, transplant preparation and duration of pollination in section of crop management and shipment place, sorting degree and management record analysis in section of business management respectively. As a result of analyzing consulting data by using standard diagnosis table of watermelon cultivation under structure which cultivated on semi-forced watermelon growers, gap between high and low level growers was 7.0 points in facility automation section, 7.1 points in environment section, 8.8 points in crop management section and 13.6 points in business management section, respectively, which were the biggest one among them. In case of excluding information-related items from the evaluation index of business management section, changes of business achievement are to occur. Therefore, it is recommended for us to review the standard diagnostic table of watermelon cultivation under structure by dividing evaluation index of management section into management and information.

This paper discusses about the e-commerce and the various types of e-commerce disputes. Through empirical examination on the dispute consideration system and by comparative analysis it is derived out of the weakness of current system and finally some suggestions for improvement. First, it is recommended that the more sophisticated knowledge concerning e-commerce should be proliferated through the existing institutions. For example, disputes for B2C could be managed by the consideration system of consumer dispute consideration in Consumer Protection Board of Korea, while B2B by the arbitration system of the Korean Commercial Arbitration Board. Second, the role of Korea Institute for Electronic Commerce established for the purpose of consideration of e-commerce disputes is much emphasized. For successful achievement, it is necessarily required to reinforce the related laws, systems, institutions and human resources. Finally, it is also suggested that the Korean Commercial Arbitration Board and Consumer Protection Board of Korea fully cover consideration and arbitration, while Korea Institute for Electronic Commerce activates its proper role of consulting and ad hoc arbitration by using electronic information. This study results are how to minimize the disputes and the method of dispute settlement. Therefore, a role of arbitration proposed and emphasized. To protect the dispute in advance, it's suggested to revise rules timely following on technical changes, and emphasized that the dispute has to lead to arbitration settlement not for consuming unnecessary time and finance for enterprises and consumers.
