This study proposes the improvement scheme of the current lease rate assessment system (2003~2014), as a major problem solving area, for the Terminal Operating Company (TOC)'s wharf since the introduction of the TOC system in 1997. The study considers the reform system using three criteria: standardization, simplification, and fairness. The final alternative presented by the study adopts the lease rate assessment system, which newly reflects changes of facilities' property values for aprons, combining it with the related fees of the Korean seaport dues for open storage yards, warehouses (shed), passages, buildings and lands within leased facilities. The proposal anticipates that the new system will not only minimize stakeholders' confusion, but also resolve the main problems within the current system. The study, further, introduces the adjustment ratio, which will make the new lease rate of the apron equal to the current lease rate of a berth, for the individual TOC's wharf, in order to prevent a sharp increment in the lease rate of the apron. This is because the government or port authorities as lessors, need to give priority to lightening the burden of TOC's costs under the deteriorating business environment such as the slowdown in port throughputs' growth. This study makes a contribution by suggesting a new lease rate assessment system for the TOC's wharf, reflecting the value of property as well as leading to its simplification and standardization. Additionally, it may lead to the improvement of fairness by applying the same rate to all leased wharfs for the lease rates of open storage yards, warehouses (shed) and passages. However, it has a limitation that hinders the fairness: the lease rate for the apron cannot be imposed in proportion to the leased area, by applying the individual adjustment ratios. In the future, those adjustment ratios should be, gradually, rationalized to be the same target ratio (0.5) for each wharf, following an improvement in the terminal operating business environment.

The buffer capacity of food waste lowers during the collecting and transportation period. Food waste usually shows deficiency of micro nutrients especially molybdenum(Mo) and cobalt(Co). Therefore, food waste can be considered as a good mixture of livestock waste to enhance methane production. The objective of this study was to investigate the correlation between properties of substrates (local food waste and livestock manure) and methane yields for successive anaerobic fermentation process and its stable management. Food wastes were taken at an intermediate storage or treatment system provided by eight local authorities (Gangnam, Gangdong, Gwanak, Guro, Dongjak, Songpa, Yeongdeungpo, and Younsan) in Seoul. The solid content and potential methane yield of food wastes were average of 16% and $446.6STP-m{\ell}/g-VS$ (range from 334.8 to $567.5STP-m{\ell}/g-VS$) respectively. As for the beef cattle manure, the solid content and potential methane yield had an average of 26% and $280.6STP-m{\ell}/g-VS$ respectively. Potential methane yield had a positive correlation with fat content, and hydrogen content and a negative correlation with carbohydrate content ($r^2>0.8$). Therefore, the potential methane yield can be predicted based on the substrate characterization results with reasonable accuracy. Further research may be needed to investigate the relation of the properties of the mixture substrate and methane production rate. The mixtures may include food waste, livestock waste, and bulking agents (saw dust, rice hull, or agricultural byproducts etc.) to determine best combination of these substrates for maximum methane production rate.

In this study, we intend to test whether experience variables such as sense, feel, think, relate, and action experiential activities of farming village can be usefully applied to revisit intention. As a result, we found that the sense, relate, and action experiences were adopted, while the feel and think variables were rejected, leading to the conclusion that Schmitt's (1999) experiential marketing theory was also applied to 6th industry experience marketing activities in rural areas. Therefore, the significant effect of rural experience activities on revisiting intention is thought to be related to the fact that they stimulated sensitivities by drawing attention and interest of consumers during the 6th industrial experience configuration, and to the environmental facilities connected to the experience site. The Feel experience has been rejected due to limitation of development of emotional element from the 6th industry certification business experience program, leading to the necessicity for development of a program that can stimulate the consumer's emotions. The reason why the Think experience was rejected is that the experience of the rural area 6th industry did not create surprises or curiosity, and thus does not meet the expectations of consumers. In case of relational experience, experiential marketing through social organizational relationship formation is expanding, and in case of behavioral experience, experience of 6th industry constitutes experience related to interaction with others and lifestyle.

Recently, tourists and sightseers are increasingly showing their interests in the native local food cultures as their living standards improve. This is why the local autonomy bodies are vigorously trying to develop their local native foods as tourism commodities, which is a part of their efforts to bring a life to their local economies. This study explores the solutions to promote the native local foods of Jeonju area as a tourism item, eventually contributing to the progress of the local economy. The target population of this study was the owners of native local food restaurants in Jeonju area, and the survey was conducted from February 10th to 25th, 2008. For data analysis, frequency analysis was used. In order to achieve this goal, analysis on local restaurant managers for their business operation should be conducted. The results showed they had daily sales of under 100,000 won and did restaurant promotions through pamphlets, brochures and so forth. The development of food was carried out mostly by the restaurant owners and the restaurant management type was independent. To activate the food tourism in Jeonju area, it is necessary to develop a representative native local food restaurants of Jeonju area as a tourism attraction, excavating new food festivals and food tourism courses suited to different areas and developing various food ingredients and spice packages.

Certain Fungi Including Aspergillus flavus produce low molecular secondary metabolite that is toxic to human and animals, which have been termed mycotoxin. Given the proper humidity and temperature like summer in Korea, are capable of growing of those hazard fungi and elaborating mycotoxin on almost any organic substrate such as traditional foodstuffs and their raw materials including rice, barley, corn, meju, doenjang and gochujang etc. Until now, some people have examined to isolate various fungi such as Aspergillus sp., Penicillium sp. and Fusarium sp. from traditional foodstuffs and raw materials, and have screened various mycotoxin producing strains. Some mycotoxin contamination such as aflatoxin, ochratoxin, deoxynivalenol (DON) and zearalenone etc. also have been confirmed from similar above samples. But these data are different each other and inconsistent in experimental conditions and methods. Especially, almost experiments have been finished for one time. So more consistent experimental method and data are necessary to evaluate objectiely the safety of traditional foodstuffs subjected to the mycotoxin. For this purpose, we have to apply a new advanced technology to develop more simple and rapid methods for determination of mycotoxin and also have to concentrate our efforts on activation of research and accumulation of technology nth sustaining investment of financial support and enlargement of research installation. With those harmonious efforts, it should be possible to examine continuously nd systematically the mycotoxin contamination in our traditional foodstuffs and to assure the safety of them. Then we can maintain and develop the better traditional foodstuffs suited to internationalization.

The unsignalized intersections in a community road in the city of Seoul have 3,753 traffic accidents(9%) of total 41,702 cases in 2008, not high in the occurrence rate of traffic accidents, but seem to have a quite high potential of accidents due to the unreasonable and insufficient operation of systems and facilities in the part of traffic foundations. In particular, the un-signalized intersections in a community road have an insufficient measure for safety as compared to the crossroads with signals, and there are few analysis of traffic accidents and domestic researches on the model of affecting factors. Our country also has no concept of passing priority in operating a crossroad without signals, differently from foreign countries, so the researches and safety measures for improving the safety of a crossroad without signals in a community road are urgent. Therefore, This study set out to analyze the road conditions, traffic conditions, and traffic environment conditions on unsignalized intersection, to identify the elements that would impose obstructions in safety, and develop a traffic accident prediction model to evaluate the safety of an unsignalized intersection using the correlation between the elements and an accident. In addition, the focus was made on suggesting appropriate traffic safety policies by dealing with the danger elements in advance and on enhancing the safety on intersection in developing a traffic accident prediction model for an unsignalized intersection.

In Korea, previous certification of water supply infrastructure was mainly focused on economical and physical aspects. Recently, hygienic safety of water supply service has become a sensitive and important issue to our people for evaluating the water quality with growth of economy and education system. According on water quality in 497 Korean water supply facilities, pH values in the supplied water have ranged between 5.8-8.5. However, little is known about metal leachability at the pH conditions observed in the real water supply systems because a fixed pH condition (pH 7.0) has been used in the current standard method, 'Hygienic Safety Testing Method', in water supply. In this work, we examined the effects on heavy metal leachability with pH differences in the water supply pipes which are typically used in Korea. As a result, the amounts of metal leachability were tended to increase when pH levels were decreased. Especially at pH 5.8, Cu leachability from Cu pipes was found to exceed the public health standard level even after applying a normalization factor (NF) given by the current Korea standard method. The Cr and Cu leached from stainless steel pipes, Cd, Pb, Cu, and Zn from Cu-based pipe fittings, and Zn from Zn-based pipe fittings were exceeded the Korean hygienic safety standards while, after applying the NF, concentrations of the leached metals were satisfied with the current Korean standard. The findings from this work provide implications on the needs of reforming the current hygienic safety standard methodology.

The purpose of this study is to systemize volunteer program for the people with chronic mental health problems to participate in helping the community as service providers not receivers, and then to examine empowerment effects of this volunteer program. The distinctive feature of this program was to volunteer the mental ill to help other people. Therefore, this volunteer program had specially strengthened preliminary stage which make not only the mental ill be ready to work but also the community to use them as volunteer, and to invite general citizen of the community as co-volunteers. The result showed this program empowered the mental disorders to have more positive self-concept. It revealed that co-volunteer's attitude toward the mental disorders was changed positively through this program, also. These results told us not only the chronic mental ill could be volunteers helping others using their abilities, but also this activity would make their self-image better and citizen's perception toward mental disorder less prejudiced. The volunteer program presented in this paper was expected to be useful for their empowerment and social integration.

Bauxite is a main raw material for the production of alumina and aluminum hydroxide in the processing plant of KC company. It is a NORM (Naturally Occurring Radioactive Materials), and its waste, red mud, is a TENORM (Technologically Enhanced Naturally Occurring Radioactive Materials). The purpose of the geochemical and mineralogical investigations of the bedrock and soils in and around the plant, a large NORM source, was to provide basic data for measuring the radiation dose and protecting from radioactive hazards. Soils were mixtures of minerals derived from the country rock (quartz, feldspar, mica, kaolin, gibbsite, and sepiolite) and bauxite (hematite, boehmite, and calcite) of open-air storage. Average U and Th contents of the soil samples were 4.7 ppm and 23 ppm, respectively, indicating somewhat Th anomaly. The average concentrations of radionuclides are $^{40}K$ 100~1,433 Bq/kg, $^{226}Ra$ anomaly in the red mud open-air storage. Soil external hazard indices range from 0.10 to 1.66 with an average of 0.63. Although most of the indices are below 1.0 that is a regulation value, those of 4 samples of total 41 soil samples exceed 1.0, requiring further detailed investigation.
