This paper is conducted to find out if the previous corporate internal reservation has a significant effect on current investment and dividend payments by using the dummy variables of each classified industry. The results of the research show that previous corporate internal reservation had a significant effect on current material investments in following fields - manufacturing industries, technical services, wholesale and retail industries, information services, construction and transportation industries - over two years. Especially, investments in tangible assets were more effective than those in development expenses. In human resource investment, previous corporate internal reservation had a significant effect on current human investments in fields of manufacturing, technical services, information services and transportation industries. Among them, investments in education training expense and welfare benefit expense were more effective than those in wages. In the dividend section, previous corporate internal reservation had a significant effect on current dividends in the fields of manufacturing, wholesale and retail, information services, transportation industries, and in other businesses. Among them, Expenditure on dividend amounts was found to be more effective than that on dividend ratio. This paper contributed to the field in a way of empirically demonstrating the effects of previous corporate internal reservation on current investments and dividends by using the method of industrial classification. On the other hand, it also has a limitation since collecting precise taxation data was practically difficult. Therefore, a further developed study is required to find out the standard which shows exactly how much the measured results of the regression analysis reflect the effects of the government policies. Moreover, it is considered necessary for the government to devise policies on vagueness and uncertainties in the domestic and overseas economic and business environments so that companies can conduct investment with confidence.

This paper is concerned with medical tourism, which is expected to become the new growth engine of the 21st century. Medical tourism is a collaborative and synergistic composition of Healthcare and Tourism, and has led to a remarkable growth in 2012 since the year 2009, exhibiting huge growth potential. This paper reviews the emerging market of the medical tourism with five major hospitals in Korea from the perspective of medical tourists, and makes suggestions for the global health care and the sustainable development in Korean medical tourism as a growth market: the construction of websites for active services and transparent management of medical expenses with proper arrangement of medical consulting and advices, cooperation of the health care center and the medical tourism industry, and the activation of healthcare communication. For the smooth progress of medical tourism, this paper suggests two separate communication channels: one for the patient tourists and the other for the medical tourism coordinators. The former needs accuracy with professional knowledge on the healthcare and communication, which should be classified as medical interpreters working with disease-oriented medical tourists. The latter refers to international medical coordinators dedicated to the smooth progress of medical tourism and services. This paper also points out the creative efforts to improve the relatively poor infrastructure of tourism industry to accommodate the medical tourists, and improve the medical tourism industry.

This study investigated a mechanism of naming a disease, as examining how obesity attain a status of disease. WHO(World Health Organization) warned 'The obesity is definitely a disease to need medical treatment' in 1996 and 1997. However, before then, obesity was classified as unusual or nonstandard body status but it was not categorized as a disease. In order to examine a mechanism how obesity attain the status of disease, this study examined the historical process of construction to obesity in discourse of disease and ontological reality of pathological epidemiological to obesity. As a result of this research, it was found that the medical community manipulated BMI(Body Mass Index) and deliberately narrowed the range of person's normal weight, and institutionalized sizism. Especially, it was found that as the medical community associated the body state of obesity with high blood pressure, diabetes, and etc that causes burden of medical expenses to patients, that was fatphobia. And it tried to from a medical control mechanism to assign obesity to an independent status of a disease. Based on this examination, this study found an entailment: the noninfectious disease such as obesity attains the status of disease not because of the pathologic reason but because of cultural or socio-economical reason which han nothing to do with any medical source.

KCTA(Korea Container Terminal Authority) is going to introduce automated operating system in the port of Gwangyang container terminal to enhance the efficiency. Prior to developing the container terminal, defining the objective of container terminal operation is essential. This research used AHP technique to define the operation objective of automated container terminal objectively, and the questionnaire to collect the opinions of future customer, operator and research institution. The objectives mix of the automated container terminal are composed of the minimization of initial investments, the minimization of operational expenses, the performance of automation system, the raising of operation efficiency and productivity and the improvement of customer service. The result of the analysis revealed that most important factor among objectives mix was “the minimization of operation expense”. Especially, the user group preferred to select the factor of “the improvement of customer service”as objective rather than select other objectives. The result of this research will suggest some guidelines for deciding the level of investment of terminal construction. information system, automation equipment, terminal worker and etc., which are to be considered in terminal development and the system development hereafter.

The economical feasibility was conducted to find the adequate method to treat the dredged sediments from agricultural reservoirs in a pilot project that had been operated to improve the quality of water and benthic environments by dredging of contaminated sediments. For benefit/cost (B/C) analysis, the net expenses were considered as the costs of project, and the benefits were calculated from the saving of waste-treatment cost through reuse of dredged sediment, the saving of construction cost of settling pond, and the values of retained water by dredging. Although the economic feasibility depended on the sites of operation, the average B/C value of the pilot project was estimated as 1.32, indicating this project is economically feasible. Depending on the treatment methods, the B/C values were in the order of the methods of coagulating sedimentation, machinery dewatering, stabilization through exothermic reaction, and soil improvement and stabilization. The machinery dewatering method is estimated as the most adequate one to treat the dredged sediments because of the minimum riskiness of secondary pollution, the recyclability, and its economic feasibility.

This study aims to compare Jeju Island, Shanghai, and Yokohama cruise ports and to investigate the relative strengths and weaknesses of Jeju Island. This study conducted comparative evaluation of 8 factors [airport, berth, expenses, distance, access to town, shopping facilities, source market (background market), and tourism] through a cruise network analysis. Comparative evaluation results find that Jeju Island, which secured 2 berths (berthing capacity) by completion of the civil-military complex port, has ascendancy over Shanghai cruise port and will have ascendancy over Yokohama cruise port once construction of the new airport is completed. Therefore, it will qualify as the best cruise port in Northeast Asia in the future. Results obtained from the cruise network analysis provide insights for administrative policy. Study limitations include only eight factors are used for evaluating the cruise-ship harbor area and surrounding hinterlands, and thus cannot sufficiently evaluate the complex conditions of the sites. In the future, it is necessary to reexamine the evaluation factors of the cruise ship harbor in detail. Furthermore, future research will need to consider the economic effects of the cruise ship industry, and its relevance to related industries as a possible fusion or hybrid industry.

The procedure that combines the result of infiltration analysis into stability analysis based on the limit equilibrium method is widely used to evaluate the impact of rainfall infiltration on slope stability. Accurate prediction of rainfall infiltration is essential to the prediction of landslides caused by rainfall, requires to obtain accurate unsaturated hydraulic properties of the soil. Among the unsaturated hydraulic characteristics of the soil, the importance of the soil-water characteristic curve describing the retained water characteristics of the soil is relatively well known and the measurement by test method to obtain the SWCC is gradually increasing. However, it takes a lot of time and expenses to experimentally measure the unsaturated conductivity characteristics of the soil. Therefore, it is common practice to estimate the hydraulic conductivity function from the SWCC. Although it is widely known that the SWCC has a great influence on rainfall infiltration, studies on the effect of the hydraulic conductivity function estimated from the SWCC on rainfall infiltration are very limited. In this study, we explained how the estimation model of the hydraulic conductivity function affects rainfall infiltration and slope stability analysis. To this end, one-dimensional infiltration analysis and slope stability analysis were conducted by using the data on the SWCC of weathered granite soil widely distributed in Korea. The applicability of each estimation model is discussed through review of the analysis results.

The amount of the Korean export & import in 1987 reached $88.3 billion which was 1.75% of the total world trade and the proportion of foreign dependence to G.N.P was 74.5%. From these facts, we can infer that the development of national economy is largely dependent upon trade. Therefore the role of transportation, especially Ocean transportation, as a basis of economic development through trade is one of the main factors that can not be passed over. Here, We can define that a port as a subsystem of transportation determines the efficiency of the total transportation system. Thus, the purpose of this paper is to contribute in improvement of the efficiency in port, reinforcement of the international competitiveness for exporting goods by the analysis of the cargo handling charges. In order to do this, this paper deals the case of B.C.T.O.C. Furthermore, this study gives some important informations related to the level of tariffs for establishing an autonomous port administration. The Summary of the conclusions of this paper is as follows ; 1) The object of port administration in Korea has been emphasized on the maximization of efficiency in using the port facilities. Nowadays, however, it should be moved to a direction that port is operated under the compound aims considering the public interests and economy. 2) For a criterian of tariff calculation, A tariff system based on the cost accounting is desirable. In general it is recommended that the cost for construction, management, and operation of port is compensated by the revenue from port operation. Therefore, it is necessary for the administration bodies of each port to establish a tariff system on the basis of the independent profit system. 3) For the investigation of actors of tariff adjustment by the Break-even point analysis, (1) When we conducted the B.E.P analysis using total cost as cost term, we got 3.8% discount in tariff at 12% of target profit rate and 1.5% discount at 15% of rate. when we set the target profit rate as 17% we could have the proper tariff level. (2) When using operating cost as cost term, we got 13.1% discount in tariff at 12% of target profit rate and 10.9% discount at 15% of rate. When setting the target profit rat as 28%, we could have the proper tariff level. 4) Comparing with the tariffs of foreign ports for the basic terminal rate, The tariff level of B.C.T.O.C showed 33% of stevedoring charge and 80% of marshalling charge incurred at Kobe port. The comparison with Singapore port gave 50% of transhipment charge and 17% - 20 % of stevedoring charge. 5) We found that the financial structure of B.C.T.O.C was better than those of other companies and the worth fixed assets ratio was too low. The fact of low worth fixed assets ratio implies that the cargo handling facilities should be increased. Moreover, The return of assets for B.T.T.O.C was good but non-operating expenses were still contained too much in. Therefore, we think that it is necessary for B.C.T.O.C. to rationalize business management. Although the present cargo handing charge for B.C.T.O.C is a proper level in terms of a public corporation, for the final recommendation in connection to the results, It is required to take the rationalization process for business management.

The Chonsei component holds the highest level of weight (5.4%) in the composition of the Korean consumer price index (CPI). The variations in Chonsei prices are directly reflected in the CPI as a representation of cost swings. The Chonsei refers to a deposit that accumulates the costs related to housing services and is mostly affected by variations in rental rates. Nevertheless, it is important to note that Chonsei prices are also susceptible to fluctuations in interest rates, regardless of the rent prices. Therefore, if Chonsei were directly and one-to-one indexed to the CPI, they could include changes other than residential service prices. After analyzing the time series data of the Chonsei index and rent index inside the CPI, it becomes apparent that the Chonsei index displays an average annual growth rate of 2.3%, whilst the rent index reveals a growth rate of 0.9%. The observed disparity in growth rates indicates a divergence in trends between the two indices. It is posited that the Chonsei index, when capitalized, has had a more rapid increase compared to the rental index, owing to the gradual drop in interest rates. To effectively reflect fluctuations in the housing service costs, proxies for the Chonsei index were utilized in the construction of a consumer price index. The findings of our study suggest that, overall, the newly developed CPI demonstrates a comparatively lower rate of inflation when compared to the official CPI. Furthermore, the inclusion of imputed rents for owner-occupied housing in CPI amplifies this effect.
