The variable message sign(VMS) is a facility to smoothen traffic flows and enable safe passing by providing real-time necessary information on roads, weather, transportation, and traffic regulations. The VMS also solves a feeling of uneasiness and gives a sense of psychological security by providing information to drivers. However, the VMS has a strong character of being a non-market product but a public product, so it has not normally been evaluated for its value. This research has evaluated a value of satisfaction level for traffic information users, using a contingent valuation method(CVM). As a result of evaluating the value of satisfaction level for users through division into an urban roadway and an urban highway for the cities where an intelligent transportation system(ITS) has been established, the urban highway had a value of 96.7 won/system and the urban roadway had a value of 76.3 won/system.

The mixed-use development project like urban regeneration project has been enforced with long period and participation of various stakeholders. For this character, lots of risk could be occurred during the process of project and the project's success or failure depends on the risk management. So the process of identifying and responding to risks in urban regeneration projects should be followed systemically. The risk identification phase is the first step to identify risk factors and define risk's character. One of the risk identification methods, the checklist, is the most practical and well-known one. This study suggests the check list that devide risks classified by stakeholders through analizing tasks of stakeholders and drawing risks. This kind of checklist which handles risk factors classified by stakeholders is an easy tool to identify risks and expected to be effective to find risks for various stakeholders and themselves in the urban regeneration projects.

This study analyzed the factors related to labor market transition of job injured workers. The Workers' Compensation Insurance Panel data ver.1, which that was surveyed by the Korean Workers' Compensation & Welfare Service in 2013, was used. Four key findings were made: first, the economically inactive populations are 7.2% and unemployed is 22.3% of occupational accident workers who finished the treatment period; second, 31.5% of laborers who returned to a new workplace went into another type of occupation; third, the results showed that socio-demographic factors, such as gender, age and education years, injury-related factors, such as the treatment period and work limitation, and workplace factors, such as company size and employment status, were associated with the return to work; and fourth, a relatively higher proportion of people who has received occupational training could not return to work and the disability grade was not associated with the return to work. These results suggest that policy makers need to understand the characteristics of labor market transition of job injured workers and develop efficient intervention programs based on the transitional labor market.

The rapid trends toward outsourcing have created more complex and fragmented multi-tier supply chains for Engineering, Procurement & Construction(EPC) industry. Working with suppliers and sub-suppliers requires continuous integration activities during project execution. The purpose of this study is to identify the factors influencing the performances and relationship satisfaction of second-tier suppliers participating in the project-based supply chain. This study proposes the network embeddedness, collaboration, information-sharing and flexibility as antecedents variables, and collected the survey responses from the second-tier suppliers having experiences with complex projects. The statistical results indicate that the collaboration with supply chain leading firm and first-tier supplier has significant impact on the performances and relationship satisfaction of second-tier suppliers. It was also found that the information-sharing and flexibility influence the network embeddedness as well as collaboration, and that the embeddedness have significant impact on the collaboration.

This paper aims to draw practical measures for the Protection of the Rights of the private security guards. The results of the analysis, and presents the legal definition if need be introduced for the protection of private security guards right, are as follows. First, it must be established in Private Security Act the basic provisions that assure the economic status of the private security guards. Secondly, there is a need to clearly define the scope of authority of private security guards. Third, there is a need to clarify the scope of physical force or power in the regulations relating to the duty of the private security guards. This provision during the "displayed its power", there is a possibility that is too arbitrary interpretation, it must be deleted. Fourth, it must be established by weighting penalties for assault of a private security guards. Finally, Private Security Act and the Petition Police Act has a difference in personality and the purpose of the enactment. So it is not desirable to be directly applied to private security guards the provisions that apply to the petition police.

Since Macintosh computer was introduced in 1984, important technological evolution has not only changed the computer graphics field but had a significant effect in the graphic design field for its judgement of aesthetic value. In Korea, the development of digital typeface and electronic pre-press business became active due to computer design system since Macintosh computer was introduced in 1987. Currently there are many digital type foundries in Korea and they have produced over 500 typefaces of the Korean alphabet. However, a few technological limitations and aesthetic problems still exist in the development of the Korean typeface. In this study, I have examined the role and function of computer technology in typography. Also I analyzed the aesthetic elements which are found in computer technology and compared them to traditional typography to try to find some opportunity and possibility for new method of development.

본 연구는 병원 근로자들의 직무스트레스와 소진의 관계에 미치는 펀 리더십과 근로자 놀이성의 조절효과를 규명함으로써 향후 병원조직의 효과적인 인적자원관리에 필요한 기초자료를 제공하고자 하였다. 연구자료는 부산지역 2개 병원에 근무하는 근로자(의사 제외)를 대상으로 구조화된 자기기입식 설문지를 통하여 수집하였으며 총 230부의 설문지를 배부하여 이 중 207부의 설문을 회수하였다. 설문 문항에는 응답자의 일반적 특성, 직무스트레스 특성, 펀 리더십, 근로자 놀이성, 소진 등을 측정하는 항목들이 포함되었다. 자료 분석을 위해 SPSS WIN 18.0을 이용하여 빈도분석, 신뢰도분석, 상관관계분석과 조절회귀분석 등을 수행하였다. 주요 결과를 요약하면 다음과 같다. 첫째, 직무스트레스와 소진의 관계에서 펀 리더십은 직접 효과는 물론 조절효과도 유의하게 나타나지 않았다. 둘째, 직무스트레스와 소진의 관계에서 근로자 놀이성은 소진에 직접적인 효과를 주는 변수임과 동시에, 낮은 유의수준(p=0.053)에서지만 직무스트레스와의 상호작용을 통해 소진을 감소시키는 조절효과가 있는 것으로 나타났다. 본 연구는 병원 근로자의 업무 수행과 관련해 비교적 관심을 받지 못했던 펀 리더십이나 근로자 놀이성 등과 같은 성격적 특성이 소진을 감소시키는 유효한 조절변수가 될 수 있음을 검증해 보았다는 점에 그 의의가 있으며, 다만 후속 연구를 통해 추가적인 검증이 필요할 것으로 판단된다.

When the construction management method was introduced, there were arguments regarding the contractual responsibility of the construction manager. Accordingly, the provisions on damage compensation in the Construction Technology Management Act were revised in 2002, and the obligatory duty of care of a good manager is now required by the Framework Act on the Construction Industry. Even though the construction manager has a responsibility of a consultant in the CM-for-fee contract, however, the Korean construction environment does not clearly specify the consultant's scope of responsibility. In this study, the theory about the duty of care, which is a consultant's responsibility among the expert's responsibilities, was arranged. Based on the responsibilities of experts such as lawyers, the duties of care of a good manager of the construction manager were presented to provide the foundation for establishing the construction manager's responsibilities. To verify the resulting items, interviews with experts were performed to assess their importance levels.

Recently, the construction industry is getting more complex and sophisticated having the characteristics of a mega project. Mega project pursues a value that can't be gained with an approach of seeing a project as just a simple sum of different parts but a mutual combination. Hence to reach the goal, program management is needed rather than project management. program management can be seen as a 'total project management' and for an efficient program management prompt support for decision making is required. However, the current supporting method can't fulfill the requirements, therefore, need a tool to support the decision making and a IETM is expected to take this role. Despite the a lot of expected advantages of IETM, it is still difficult to apply because of the frequent changes of information in specifications and laws. In this research, as part of developing a IETM, we aim to propose a system frame which is based on the analysis of processes of a project. Moreover, based on this frame, a database will be built to contribute towards the application of construction IETM in the domestic construction industry.
