The government promotes the 2050 carbon-neutral policy. Therefore, the concern to convert livestock manure into energy is increasing for the reduction of greenhouse gases generated in the livestock industry sector. In this study, the economic feasibility of the livestock manure solid fuel power generation facility, which is a major consumer of livestock manure solid fuel, was assessed to expand the demand for livestock manure solid fuel. The production cost of livestock manure solid fuel showed the lowest production cost of 97.4 thousand won/ton when dried using solid fuel at a 200 ton/day scale bio-drying facility. The livestock manure solid fuel power generation facility showed economic feasibility at a REC weight of 1.5 in the case of the bio-drying facility, so it was necessary to set a REC weight of 1.5 or more to expand the demand for livestock manure solid fuel. The conversion of livestock manure into solid fuel has various environmental benefits, such as the reduction of greenhouse gases and the effect of reducing non-point pollutants in the water system. Therefore, in order to expand livestock manure solid fuel production facility, it was required to review the feasibility including various environmental benefits.

Poitical demand for decentralization trends in Korea has led the government to plan to localize its agricultural extension system by changing the status of 6,696 extension personnel stationed at the provincial and county level from central government status to local government status as of January 1997. However, serious drawbacks of lowered morale of extension personnel and the financial burden of local governments has not yet been debated extensively for effective personnel management. Some of the findings that emerged from both the analytical and empirical research show the dangers of decentralization such as an increase in disparities, jeopardizing stability, and undermining efficiency. These problems should be considered along with the culture, tradition, and Koreans' attitude towards central and local government. The dangers of decentralization of agricultural extension services in Korea may cause serious problems in allocative efficiency because of a mismatch between available resources and promised expenditures, and in production efficiency because of unproven cost-effective provisions of local governments. It is accepted that the central government can invest more in technology, research, development, promotion and innovation in the agricultural sector. However, changing the status of extension personnel from central government to local government status may lead the best people to leave, lower morale, shake the sense of public service, break networks, and sacrifice investment in research, development and extension. In deciding the future directions for personnel management of agricultural extension services in Korea, maintaining or reinforcing the existing national status of extension personnel should be considered along with a reflection of the basic characteristics of agricultural extension services, linkages of research and extension, the financial burden of local government, specialization of extension personnel, unnecessary duplication of investment among local governments, possible national supports to agricultural research and development, and extension under the WTO systems.

Freight travel pattern has been less studied comparing with the field of passenger travel. Nonetheless, the importance of the freight travel has been increasing in urban travel sector, and the research needs on the freight travel demand hence is increasing. The current paper aims to identify, by tons of freight trucks and cargos, the characteristics of mean travel pattern, efficiency or performance, and the characteristics of freight trip chain regarding destination location, destination type and freight type. The study analyzed the nation-wide data of freight travel behavior survey. This study intended to set the starting framework of decision-making principle in freight travel, which has already been popular in passenger travel study. Findings suggest that those characteristics are clearly distinguished among trucks and cargos of different sizes of tons. The results are expected to provide important insight to the development of relevant transportation policy measures.

Purpose: The aim of this study was to investigate the association between job stress and metabolic syndrome among male workers. Methods: A total of 396 male workers employed in an electronic company, located in 'P' city, Gyeonggi Province, who had taken medical examination at the 'D' hospital, volunteered in this study. All the data used in this study were obtained from 'D' hospital after getting consent and permission from the workers. General and occupational characteristics, medical history, and health-related behaviors of the subjects were obtained by self-administered questionnaire. Results: The highest occupational stress by sub-sector was reported in the order of insufficient job control, organizational system, lack of reward, job demand, job insecurity, physical environment, job culture, and relationship conflict. The prevalence rate of metabolic syndrome of the participants was 19.9%. The results of the multiple logistic regression analysis on metabolic syndrome of the subjects indicated that the syndrome was significantly higher among those with family history, smoking habit and ex-smoking, working duration of 3 years and over, and with higher total score of occupational stress. It was significantly more prevalent, when the degree of stress was high in the sub-sectors of occupational stress; job autonomy, job insecurity, lack of reward, and job culture. Conclusion: In conclusion, it is necessary to implement a plan to efficiently manage the job stress of these male workers, as the probability of metabolic syndrome increased with the increase of occupational stress. Furthermore, considering the highest occupational stress was found to be job autonomy among its sub-sectors, it is necessary to prepare various measures to enhance the autonomy of such employees.

The demand for specialized human resources capable of bringing about highly advanced logistics systems and the integration of logistics centers situated in local hubs, has been on the rise. Logistics industry requires more of a systematic mind set, endless innovation, and the navigation of uncharted waters than the logistics industry. This study lays out the reasons for the importance of developing human resources in the logistics industry, and then carries out an evaluation of the current state of human resources development in that particular field in Korea. This study found that there is not only a shortage in terms of the courses needed to develop the skills required to carry out the core activities associated with the logistics sector, but also that students' ability to speak English and Chinese, which are ubiquitous in the international logistics industry, was also wanting. There is a need for the study of logistics at the university level to be based on practical applications rather than theoretical ones.

Six countries are considered in the study for the comparison of their respective gas industries with the Korean gas industry: the U.S., Canada, the U.K., France, Germany and Japan. The emphases of comparison are given on the cross-evaluation of industry organizations and related regulations. In terms of industrial development stages, the Korean gas industry, with its short experience and in need of more infrastructure, is still young and at an early stage of development. Due to this reason, the study finds that it is premature for the Korean case to propose some policies like the promotion of competition in the gas transportation through third-party access to pipelines. or seeking overseas business opportunities requiring venture capital and advanced technology. Recommendations are made that Korea rather, for the time being, concentrate its energy on the construction of infrastructure and on securing supply sources and diversifying import origins, in order to strengthen it's supply capability in the face of rapidly increasing gas demand in the nation. Nevertheless, Korea will soon have to consider more seriously about the deregulation of the market and more diversified business activities through the development of high technology and managerial skills.

The concept of SIL is applied in the most of all standards relating to functional system safety. However there are problems for the people to apply SIL to their plants. as these standards don't include sufficient informations. In this regards, this paper will suggest the direction of SIL application and concept based on IEC 61508 and IEC 61511. A Safety Integrity Level(SIL) is the discrete level(one out of possible fours), corresponding to a range of the probability of an E/E/PE (Electric/Electrical/Programmable Electrical) safety-related system satisfactorily performing the specific safety functions under all the stated conditions within a stated period of time. SIL can be divided into the target SIL(or required SIL) and the result SIL. The target SIL is determined by the risk analysis at the analysis phase of safety lifecycle and the result SIL is calculated during SIL verification at the realization phase of safety lifecycle. The target SIL is determined by the risk analysis like LOPA(Layer Of Protection Analysis), Risk Graph, Risk Matrix and the result SIL is calculated by HFT(Hardware Fault Tolerance), SFF(Safe Failure Fraction) and PFDavg(average Probability of dangerous Failure on Demand). SIL is applied to various areas such as process safety, machinery(road vehicles, railway application, rotating equipment, etc), nuclear sector which functional safety is applied. The functional safety is the part of the overall safety relating to the EUC and the EUC control system that depends on the correct functioning of the E/E/PE safety-related systems and other risk reduction measures. SIL is applied only to the functional safety of SIS(Safety Instrumented System) in safety. EUC is the abbreviation of Equipment Under Control and is the equipment, machinery, apparatus or plant used for manufacturing, process, transportation, medical or other activities.

To cope with recently increasing demand for data traffics, heterogeneous networks have been actively studied, where small cells are deployed within a macro cell coverage with the same frequency band. To mitigate the interference from the macro cell to small cells, an enhanced Inter-cell Interference Coordination (eICIC) technique has been proposed, where ABS (Almost Blank Subframe) is used in time domain. However, there is a waste of resource since no data is transmitted in a macro-cell in ABS. In this paper, we propose a new interference management method by using a 3D sector beam based on Active Antenna System (AAS), where Genetic Algorithm (GA) is applied to reduce the antenna gain toward a small-cell. With the proposed scheme, the macro-cell and small cells can transmit data at the same time with the AAS antenna pattern generating reduced interference to small cells. The performance of the proposed scheme is evaluated by using an LTE-Advanced system level simulator.
