  • The main aim of the study is to test a house pricing model by combining hedonic and asset-based pricing models. An understanding of the relationship between house pricing and its return (the rental income) helps to establish houses as a significant asset class. The model tested the relationship between house pricing (dependent variable) and the house attributes (independent variables) derived from Freeman's framework of housing attributes. This study uses a large data-set of 1,899 sample of new, high-end houses purchased between 2016 and 2019 collected from the national capital region of India (Delhi-NCR). The algorithm was built in R-Script, and stepwise multiple linear regression was used to analyze the model. The analysis of the model proves that the three significant variables, namely, carpet area, pay-off, and annual maintenance charges explain the price function. Further, the model is statistically fit. The major contribution of the study is to understand the key factors and their influence on the house pricing. The model will be helpful in risk assessment in the housing investment and enhance the chances of investment. Policy-makers can use information about the underlying valuation drivers of the house prices to stabilize the market and also in framing the tax policies.

  • Korea's marine products trade is taking for phase that income exceeds export after 2000. According to external environment change of Korea and Japan fishery agreement and an import liberalization of marine products, import of live fish and fresh fish is increasing rapidly. This study investigates import view of Japan live fish and fresh fish. Live fish which is imported from Japan has red seabream and seabass, but it is in declining tendency because of the increase in import of cheaper croaker from the China. If see importer's trend, entry to import business of fresh fish is eased a little. If a circulation trend is seen, However, it is thought that a future import trend is influenced by economic trends of Japan and the grade of place-of-production development of a domestic trader. Circulation market outside is common and the district wholesale store has played the important role. The import view of Japanese live fish and a fresh fish will increase against the background of maintenance of domestic circulation organization, and upgrading of marine product consumption However, it is thought that a future import trend is influenced by economic trends of Japan and the grade of place-of-production development of a domestic trader.

  • Rice cultivation is not only the main resource of farm income and staple food but also the root of cultural life of Korean people. Korean government has carried out irrigation water development with heavy investment to cope with water shortage in rice fanning as a link of the five years economic development plans. In spite of the continuous accomplishment of irrigation water development, the marginal benefits-costs of irrigation water has not been studied. Owing to the government full support for the operation and maintenance of irrigation facilities, price of irrigation water as a membership fee could not be formed as the municipal and industrial water prices. Accordingly this study is aimed at identifying firstly the marginal benefits-cost of irrigation water, secondly deriving the macro-econometrics models as supply and demand functions of irrigation water and thirdly examining the marginal benefits-cost ratio. The trends of supply and demand prices of irrigation water were estimated annually. Considering the marginal benefits-cost ratio as 1.3, it was identified that additional irrigation water development projects still have an economic feasibility under the present economic situation in Korea.

  • Fisheries resources living in inland have continuously reduced due to over-fishing and development thoughtless for the environment. Inland fisheries that target the fisheries resources have been also confronted by several problems such as insufficiency of inland fisheries management systems, inconsistent fisheries management system, inferior infrastructure of inland fisheries, and decreasing fishermen's real income. These problems have demotivated fishermen who want to focus on fishing and farming activation. Therefore, this paper provides alternatives of reorganization for turning to sound and healthy inland fisheries industries by reviewing Korean inland fisheries management systems. The reorganization should be preferentially granted resource management by water system considering geographical conditions, seed release, and establishment of fisheries order for maintenance of sound and healthy inland fisheries. Also, the reorganization should be moved toward the competitive strengthening of "company unit" for inland fisheries, the nourishment of fisher-oriented fisheries management system, strong relationship among inland fishermen, the systematic management of inland fisheries, the strengthening of guidance service for inland fisheries, the extension of infrastructure related to fisheries production, the development of inland fisheries policy including public people, and the improvement of inland fisheries system and law reflecting various users of inland fisheries.

  • Private financing is playing an increasing role in public infrastructure construction projects worldwide. However, private investors/operators are exposed to the financial risk of low profitability due to the inaccurate estimation of facility demand, operation income, maintenance costs, etc. From the operator's perspective, a sound and thorough financial feasibility study is required to establish the appropriate capital structure of a project. Operators tend to reduce the equity amount to minimize the level of risk exposure, while creditors persist to raise it, in an attempt to secure a sufficient level of financial involvement from the operators. Therefore, it is important for creditors and operators to reach an agreement for a balanced capital structure that synthetically considers both profitability and repayment capacity. This paper presents an optimal capital structure model for successful private infrastructure investment. This model finds the optimized point where the profitability is balanced with the repayment capacity, with the use of the concept of utility function and multi-objective GA (Generic Algorithm)-based optimization. A case study is presented to show the validity of the model and its verification. The research conclusions provide a proper capital structure for privately-financed infrastructure projects through a proposed multi-objective model.

  • Recently, resettlement problems of low income groups in the urban regeneration area have been issued in Korea because they have no capability to purchase (or lease) redeveloped housing (or apartment). There are several approaches for supplying affordable housing and one of these is the bidding system which can reduce construction cost. However, the lowest bidding system has many problems such as dumping and substandard quality. In this context, this study proposed bidding system based on technical proposal applying the concept of the lowest total combined bid price for optimization of bid price, reduction of construction cost and period, and maintenance of suitable quality. This bidding system embraces the best value and cost plus time concept on the basis of an improved lowest price bidding system. It consists of the following components: work unit based, project unit based, and period reducing technical proposals. The proposed bidding system for determining bidders are designed to evaluate the adequacy of each technical proposal in the order of the combined minimum price in an effort to effectively optimize bid prices and reduce the construction periods, as well as to maintain a minimum appropriate quality.

The collected date were analized by S.P.S.S. program(frequency, percentage, mean, t-test, ANOVA, Pearson Correlation). The results of the study were as follow. 1. The mean of the degree of mothers' stress was 3.681. Of the stress categories, illness treatment (4.216) was highest, and the next were in order of ill-ness status and prognosis(4.154) , family relation-ships and personal roles(3.202), interpersonal relationships(2.916). 2. The mean of the degree of mothers' coping method was 2.930. Of the coping method categories, communication with medical team or parents in similar situations(3.332) was highest, and the next were in or-der of family cooperation and optimistic thought about the situation(3.241), reforcement of self esteem and maintenance of psychological stability(2.538). 3. There was not seen a stastically significant correlation between stress factors and coping methods of mothers. But with categories, the higher the stress to illness status and prognosis was, the hight coping methods' degree of communication with medical team or parents in similar situations was shown a positive correlation, if not high (r=.2776, P=.046) . And the higher the stress to illness treatment was, the higher coping methods' degree of communication with medical team or parents in simial situations was shown a positive correlation, if not high (r=.2727, P=.049). 4. With the difference of stress according to mothers' general characteristics, religion and monthly income shew a statically significant difference. The mothers' group who have a religion shew the higher degree of stress(t=-3.17, P=.003), The group who get the most income shew highest degree of stress (F=.4693, P=.0156). With the difference of coping according to mothers' general characteristics, the most support-ing person, satisfaction with husbands and mothers' own health status shew a statistically significant difference. The group who get the most support from parents-in-law(F=3.7508, P=.013), the group who are much satisfied with husband(F=3.589, P=.016), and the group whose health status are good(F=3.3675, P=.046), shew the highest coping degree. 5. There were no significant difference in degree of stress and coping by children's characteristics The significance of the study will be concluded as follows. 1. Investigating the stress factors, which mothers are perceiving, it will be utilized as the basic materials of nursing plan so as to reduce the stress of mothers. 2. In searching for the ways of mothers' more helpful coping methods, it shows the necessity of the active nursing intervention for the mothers in the process of coping with their stress.

  • The purpose of this study is to examine the effect of urban decline on Subjective Well-being(SWB). According to the scale of the city, the municipal districts of Korea are classified into metropolitan cities, middle cities, and small cities. The SWB in the growth area, the maintenance area, and the declining area according to the degree of relative decline of each city group was examined. In addition, in order to consider the complex nature of urban decline, SWB was divided into overall life satisfaction, household income satisfaction, and housing environment satisfaction. Panel models were also used to identify the dynamic relationship between the progress of urban decay and the change in SWB. The empirical analysis of this study examined the effect of decline on the SWB for the local residents. As a result, it was confirmed that the effect of urban decline on the SWB of the residents varies according to the size of the city where the individual resides, according th the SWB by the division. In the case of metropolitan inhabitants, the decline of the housing environment of the residents due to deterioration of the physical environment was confirmed as a result of the decline of the city, but the overall life satisfaction was increased due to the decrease of the social costs such as congestion in an overcrowded area. On the contrary, in the case of the residents of the small cities, it is confirmed that the decline of the city reduces the overall life satisfaction, household income satisfaction, and housing environment satisfaction.
