  • 디자인에 관련된 대부분의 사람들은 제품 심미성이 소비자 선호에 중요한 영향을 미친다는 것을 부인하지 않는다. 따라서 디자인 분야에 있어서 제품 심미성에 관한 연구는 아주 중요한 의미를 지니고 있는데, 그것은 제품 심미성에 관한 연구가 제품의 심미적 요소 평가에 대한 지침을 제공해주고 또한 제품 심미성이 소비자 선호에 어떻게 영향을 주는지에 대한 통찰력을 제공해주기 때문이다. 나름대로 지대한 공헌들이 있었지만 제품 심미성을 어떻게 평가하고 그것들이 소비자 선호에 어떻게 영향을 미치는지를 설명할 수 있는 이론들은 아직 형성단계에 있다. 본 연구의 목적은 제품의 어떤 측면들이 소비자들로 하여금 선호할 수 있는 것으로 고려되는 지를 체계적으로 설명할 수 있는 프레임 ?을 제공하는 것이다.

  • In the sea-floating logistics port called mobile harbor a crane system with the different structure from the conventional above-ground container crane is installed. And, the dynamic stability of whole mobile harbor by the wave excitation is definitely affected by the crane positioned at the top. This paper is concerned with the dynamic rolling analysis of the mobile harbor subject to sea state 3 wave excitation, for which two-step analysis procedure composed of theoretical and numerical approaches is employed. First, the rigid rolling of mobile harbor is obtained according to the linear wave theory. And then, the dynamic rolling response of the flexible crane system caused by the rolling excitation of mobile harbor is analyzed by finite element analysis. The coupled interaction effect between the sea wave and the mobile harbor is taken into consideration by the added mass technique.

  • This paper provides a theoretical approach to the New Zealand's Catch-Balancing Regime (CBR) with a reporting requirement under the Individual Transferable Quota (ITQ) system. The enforcement strategy depicted draws on recent literature regarding practical applications of the Revelation Principle. New Zealand's use of CBR-specific instruments such as deemed values, remains to be improved. However, some of its features can constitute a valuable example for regulators seeking to improve their methods of dealing with issues as bycatch or overfishing in order to maintain Total Allowable Catch (TAC) levels under emerging ITQ systems. The enforcement strategy analyzed has the potential to provide a more sustainable and efficient management of the fish stock, reduce discarding and stabilize monitoring costs, while improving the level of reporting compliance.

  • Since the 1980s, the academic interests on the regional geography have been renewed. This trend is usually called 'Renaissance' of the regional geography. Given this context, to explore diverse theories and methodologies in the regional geography is of much significance. Particularly, to examine the regional geography in Germany widens the understanding of not only the history, strength, and weakness of the regional geography, but also the discipline's status in the field of geography. This paper discusses the regional geography in Germany before World War II, focusing on varieties of theories and methods as well as the historical trajectory of the German regional geography. This discussion may well be significant in that 'Laenderkunde' became an important paradigm in the discipline of geography in Germany during the pre-World War II period.

  • Today's policing is toward to the Community Policing. Despite its widespread popularity, there exists a lack of common understanding among academics and practitioners alike regarding the scope of the community policing philosophy and of its ability to integrate these complementary ideas within it. These are Problem-oriented policing, broken windows, Compstat, third-party policing, and hot spots. We will present a definition of community policing and demonstrate how these other policing approaches can be incorporated into the overarching community policing philosophy. We will also discuss the potential benefits of taking such a unified approach with the hope of encouraging further integration among policing innovations.

  • I examine the situation in which the players compete to obtain economic rents which is generated by the market-based environmental regulation, such as carbon taxes or tradable permit allocations. Drawing on contest theory, I employ the sharing rules which is devised to motivate players best effort, and consider two models in carbon taxes: one model with observable sharing rules and the other model with unobservable sharing rules. I show that, first, the overall welfare of carbon taxes is always less than that of tradable permit allocations under the model with observable sharing rules. Second, depending on the share of the preassigned allocation in tradable permit allocations, the overall welfare of carbon taxes may be larger than that of tradable permit allocations under the model with unobservable sharing rules.

  • In this paper, we discuss the role of allocative efficiency and X-efficiency in determining resource allocation under the share tenency. Economic efficiency of resource allocation is related to land reform. Classical and neoclassical schools insist that land reform must be achieved for agricultural development by more efficient use of inputs. According to them, there is no incentive for tenants to use inputs until $MVP{\ell}=wage$ under the share tenancy. But "equal efficiency" school's conclusions are different. They conclude that there is no productivity differences between owner cultivation and share tenancy, owing to monopoly power of landlords and/or landlords's transaction costs. Considering X-efficiency, the share tenancy is not as efficient as the owner cultivation. On the other hand, the productivity differences may be reverse, in which landlords cultivate their lands by wage contracts. Land reform--reduction of land rent or redistribution of land--will be benefitable not only for agricultural development, but also for resource allocation in farm management.

  • The factors that affect on the ratio of monthly rent to total rents in commercial real estate lease contract was empirically investigated. The theoretical basis for the research was location theory, retail trade-area analysis, bid rent, agglomeration theory, and demand externality theory. The data used in this study included information on goodwills per 3.3 square meters, deposit money per 3.3 square meters, retail rents per 3.3 square meters, and passing pedestrians' characteristics in 96 retail trade areas in South korea. As the results, using the hedonic price functions and multi-regression analysis, the independent variables does affect the ratio of monthly rent to total rents in the each retail trade area were goodwills per 3.3 square meters, deposit money per 3.3 square meters, retail rents per 3.3 square meters, and the number of Small Wholesale Retail Trade Firms at the level of nation. also, the results show goodwills per 3.3 square meters and the number of Small Wholesale Retail Trade Firms are important factors in determining the ratio of monthly rent to total rents in commercial real estate lease contract in seoul. In summary, not only the economic conditions in the retail trade area but also the passing pedestrian count should be considered to determine the ratio of monthly rent to total rents in commercial real estate lease contract.

  • The organic law on the Construction Industry, initially, this law was enacted with a view to preserving and fostering the specialty of each type of industry. By dividing each construction business boundary, it gradually settles the system of construction specialized on the basis of productive stages. Controversy over the abolishing regulations on business boundary still continues to swirl. Since the intensity of exclusion as well as rigidities become increased. This results from the fact that informations are not shared among business boundary and businesses under the protection of the business boundary regulations choose 'rent-sicking activity'. According to dissidents against this law, structure should be established not by artificially enforced institution but by voluntary efforts of participants in construction industry. This paper aims at improving the competitive of the construction industry by showing the efficient system of construction and proving the legitimacy of abolishing business boundary
