Recently, International institution such as IMO and major maritime countries have introduced various regulations and steps to reduce port pollution. However, recognition of environmental pollution from ports is not sufficient for Korean policy makers and port communities. The purpose of this paper is to examine solutions to port pollution problems and suggests some implications to Korean ports to become a green port. To this aim, necessity of regulation on environmental pollution from port operation; literature survey on port's environmental pollution; current conditions of international port pollution; various regulations and policies governing major ports are conducted in this paper. Our main findings are as follows; first, air pollution from ship can be reduced by providing electric power at docks while at berth, Second, in case of cargo-handling equipment, retire old equipment and switch to cleaner fuel such as low-sulfur fuel and diesel emulsions. Third, offering incentives for the installation of pollution controls and minimizing idling by enforcing idling limits or by installing idle shutoff controls can be recommended for reduction of air pollution of truck and rail at ports.

The purpose of this research is to investigate the factors which effect the intention to reemploy after the retirement and the mediation effect of the social capitalism for retired and prospective retired baby boomers. Starting from 2010, baby boomers have been retiring at a large scale. However retirement at a large scale without securing provision for fiancial wise in later life can lead to many issues regarding social and fiancial wise such as instability of labour market and increase of spending in society welfare cost and such on. Change of individual's self prospective and institutional support to help prepare find new career for next 3decade after the retirement needs to be concretized. Also, while in the work force, potential retiring baby boomer workers should be systematically supported with education, training and reemployment program based on individual's career orientation and allowing them to stay for a longer period in the labour market can be the implication to the solution for the economic stability and increasing social cost such as public pensions.

The purpose of this study was to criticize the sport culture of babyboom generation women in Korea society. In the traditional society with Confucianism dominating, women were told to walk in small strides with modesty, keep footsteps narrower than the size of foot and never run frivolously. But in the modern society, many middle aged women-babyboom generation who was born in 1955-1963 and the first generation was served high level education engaged to enjoy various physical activities. For this study, there is a important method to analysis through three oral history interviews. It can be seen the cultural context in the result of sport as a play, restricted P·E class, forced motive-a good motherhood, survival fitness and ready for later life. These results will can be founded as a reality of dynamic relations and provided implications about founding the important of women voice and creating important data for people who want to be engaged in sports as a physical activities.

This paper examined the problems concerning recognition of business selection and operation, etc. and the presentation of the corresponding improvement measures. For this purpose, according to the results of a questionnaire survey on recognition of detailed business operation of the fire safety shared tax, satisfaction in business execution, financial operation measures for the subject of fire fighters, fire fighters have been shown to be indifferent to the detailed business field of fire safety shared tax, investment contents, etc. in the operation of fire safety shared tax. In terms of satisfaction after execution of the shared tax, reduction of the aging rates for firefighting equipment and improvement of dissemination rate was shown to be high with Fire Sergeant (M = 3.70) and a service duration of more than 16 years (M=3.64). To improve the measures of finance, there was considerable feedback saying that the reduction in state subsidy was inappropriate. In view of the diversification and development of the fire safety shared tax businesses being operated on a limited basis along with the overlap of most state subsidy businesses with safety field businesses, legal system improvement is needed for the stable securing of insufficient firefighting financial resources so that the full amount of shared tax can be invested in firefighting fields.

Pump car is an equipment that transports concrete products as needed to the place where they are poured. In order to pour a large amount of concrete in a short period of time, using a pump car is the most efficient in terms of economic efficiency and quality control. However, recently, many casualties have occurred due to boom damage during concrete pouring, so this study suggests that improvements are needed in the equipment manufacturing stage, inspection standards for old equipment, and equipment rental system. The reason is that, as a result of the finite element analysis of the pump car, the significant stress acting at the second stage of the boom and the maximum stress at the top of the boom were found to be 895.39 MPa, and M.S. Since it was evaluated the lowest at 0.04, the need for reinforcement was recognized. And it was confirmed that the 2nd stage boom was the most stressful and vulnerable part of the 1st to 5th stage booms. Therefore, it is necessary to increase the thickness and rigidity of members at the design and manufacturing stage, and to reinforce the steel plates of currently used equipment. In addition, it is urgent to establish a system that makes non-destructive testing mandatory for all general construction machinery and holds inspection agencies responsible for missing boom defects during non-destructive testing and regular inspections.

Currently, in Korea, due to the rapid aging and deterioration of facilities, the minimum Maintenance Level and Performance Level' of facilities are required by the 'Facility Safety Act' or 'Infrastructure Management Act'. Since infrastructure assets have a long lifespan and the pattern of deterioration over time is complex, it is very difficult to maintain infrastructure as 'minimum maintenance state' or 'minimum performance state' by the current way of management. 'Asset Management' shall be performed not only by a technical perspective, but also by an accounting perspective such as cost and asset value. However, due to lack of awareness of 'asset management' among stakeholder, only technical perspective management is being carried out in practice. In order to effectively manage infrastructure assets, complex consideration of various asset value factors such as budget and service as well as safety and durability are required. In this paper, we presented a theory to evaluate and quantify the road network value for efficient asset management of the road network. We also presented a method of simulation to apply the theory presented in this paper. Through simulation and the results derived from this study, it is possible to specify the budget for the future national asset management, and to optimize the strategy for the management of old road facilities.

This study analyzes the multiple effects of the following three aspects of waterscape facilities within apartment complexes: planning/designing, maintenance/management, and use of the facilities and suggests primary documents that will be fundamental for the methods to accelerate the implementation of waterscape facilities. A survey and analysis was conducted among a few of the most representative private apartment complexes in Seoul in accordance with the management and operation of waterscape facilities. The analysis used frequency analysis, descriptive statistics, reliability test, t-test, and PLS regression analysis. The research findings are as follows: first, the degree of use of waterscape facilities was found to be low regardless of the levels of operation, but residents' preference for the facilities was shown to be high, thus indicating there are still high expectations on the part of residents. Second, regardless of whether the facilities are being operated efficiently, the two items of location and display method under the section of planning and designing and the two items of aptitude and convenience under the section of use were found to positively affect the operation and use of waterscape facilities. Particularly, the item of freshness, cleanliness was shown to be directly and indirectly correlated with obsolescence, administration costs, and noise, which negatively affect the operation. Third, it was found that the administration costs itself that had been shown as the most negative factor of operating landscaping facilities in previous research did not cause problems in the residential area where the facilities are not operated efficiently. The finding suggests that the administration costs do not matter but that in the case of experience- and entertainment-typed facilities that residents want, they are linked to problems that do not introduce the desired facilities. Fourth, it was found that various aspects of planning, designing, maintaining, and using facilities interconnect and affect one another in the process of operating and using waterscape facilities resulting in the need to have a comprehensive approach to these three factors of planning, design, maintenance, management, and utilization. This study proposes that the needs and values of residents should be reflected to activate the introduction of landscaping facilities in the apartment complexes.

Change of individual's self prospective and institutional support to help prepare find new career for next 3decade after the retirement needs to be concretized. The results of this study suggest that the management orientation affects the social capital positively and the autonomous orientation does not affect the relationship between career orientation and social capital. In terms of the relationship between career orientation and reemployment intention, management orientation does not affect the intention of the entrepreneur but affects the reemployment intention positively, while the autonomous intention affects neither entrepreneurial intention nor reemployment intention (+), Respectively. Social capital has a positive effect on the intention of reemployment, and the mediating effect of social capital on the relationship between career orientation and reemployment. Also, while in the work force, potential retiring baby boomer workers should be systematically supported with education, training and reemployment program based on individual's career orientation and allowing them to stay for a longer period in the labour market can be the implication to the solution for the economic stability and increasing social cost such as public pensions.

The purpose of this study is to analyze the influence of the nation's institutional environment on start-up intention of employees and the mediating role of risk-taking propensity in the relationship between these variables. This study classified the institutional environment into institutional profile regulation, institutional profile norms, and institutional profile recognition. The research data were collected through questionnaires for office workers belonging to domestic companies, and 322 copies of questionnaire data were used for hypothesis verification, except for questionnaires that were omitted or unfaithful. The results of this study are as follows. First, institutional profile regulations and norms were positively related to start-up intention of office workers, while institutional profile cognition had no significant effect on the start-up intention. Second, institutional profile regulations and norms were positively related to risk taking, while institutional profile cognition had no significant effect on risk taking. Finally, risk taking was found to partially mediate the relationship between institutional profile regulation and start-up intention, and completely mediate the relationship between institutional profile norms and start-up intention. The theoretical implications of this study are as follows. First, this study makes a theoretical contribution in that it revealed that the country institutional profile regulation and norms are important prerequisites for start-up intention and risk taking. Next, unlike previous studies, this study makes a theoretical contribution by presenting a start-up intention model of office workers consisting of perception of the institutional environment and risk taking, which is the individual characteristic of entrepreneurs. The practical implications of this study are as follows. First, the government and local governments should strengthen regulations on institutional profiles so that start-ups can be activated. Second, the government and local governments should strengthen the norms for institutional profiles so that start-ups can be activated. Finally, the government, local governments, and educational institutions should devise measures to strengthen the risk taking of start-ups.
