Design sector, one of the key factors defining national competitiveness and one of the creative industry, needs multi-functional and differentiated designers as its structure has changed to knowledge-intensive industry. Design sector is now following the trend of social change through frequent exchanges and joint researches with other sectors. However, education for human resource nurturing in the sector falls far short of social demand for change. As the industry still focuses on educating modeling issue handlers, the problems of excessive supply of human resources in particular sector and imbalance of supply and demand of human resources are adding extra difficulties to the already competitive designer employment market. Against this backdrop, this study recognized that design service sector, which began to be established as a new industry sector, has potential of becoming one of the new domains of movement for designers, explained the necessity of education in the field, and specified practical contents of design work. Also, It analyzed work contents of design service sector, classified them into each stage, and presented them to use in design professional nurturing education.

Korea's construction industry experienced no difficulty managing the costs of finishing work items in the apartment housing field thanks to the uniform specification and the standardized costs of finishing work items. Finishing work items have continuously become more high class and differentiated, which has caused the costs of finishing work items to rise. This study identified problems with the cost management when planning finishing work items and choosing their alternatives based on the current process applied to the planning stage of finishing work items. It also found problems with the information management of finishing work items including design, cost, and work information that took place in bulk. Based on the identified problems, the design, cost and work information of finishing work items was integrated so that they could management the costs and information when planning finishing work items and selecting their alternatives. Then a cost-based information management process was suggested for finishing work items by improving each of the project cost management elements. Finally, an information model for finishing work items was built by studying the ways to integrate the information hierarchy and library of finishing work items.

The purpose of this research is to reveal the problems of the Western based development discourse, and to derive the future direction of postdevelopment as sustainable development. This study attempted to reveal the historical process of formation and change on development discourse. Development generally regarded as the overcome of underdevelopment, inducing the marginalization of the South as a place to follow the development model of the North. State based development discourse (Keynesian development discourse) focused on the growth by industrialization, and the supreme aim of the South was to overcome the underdevelopment. Neoliberalism development discourse emphasized on the market principle based on free competition which was recognized as the best way to provide development. However, neoliberalism discourse has been criticized for the concentration of power and inequality of class, causing on the consideration of postdevelopment because of its emphasis on growth rather than distribution and life value. This research revealed the ways of postdevelopment with fair trade and ethical consumption. However, fair trade and ethical consumption discourses clearly show somewhat limitation subsuming into neoliberal development discourse. In this respect, future ways for postdevelopment have to consider the overcoming of powers based on market and capital, and to orient into the value of redistribution in development process.

This study investigates a comprehensive context between the vertical integration and concentration of Korean film market. The concentration of distribution and screening markets are result of industrial strategy to defend demand uncertainty and to pursue economies of scale. Major distributors are increasingly inclined to defend industrial risk by concentrating resources on blockbusters and bargaining power of the multiplex is getting strengthened by distribution competition to secure as many screens as possible. Vertically integrated multiplexes operate discriminatory preferential treatment to their affiliates, however, there is a difference in degree of discrimination between vertically integrated groups. Furthermore, it is difficult to exclude each other from the distribution competition in which the largest screen number has to be secured. It is difficult for multiplex only to pursue the interests of affiliates and make negative choices in screening performance. As the number of screening screens increases, the seat occupancy also increases. As a result, the polarization of the distribution and screening markets, including the screen monopoly, is a phenomenon that occurs commercial films centered markets and the unfair behavior of the vertically affiliated multiplex has a limited effect on the movie market.

Competition between ports around the world is intensifying to attract transshipment cargo. However, recently, there have been concerns about the departure of transshipment cargo volume at Busan Port, such as the lifting of the cabotage policy in China's shipping sector and the implementation of a safe fare system. In terms of operation, terminal congestion and vehicle waiting time are seriously occurring due to imbalance in the transshipment volume of each terminal and vehicles concentrated in a specific time period. In this paper, we propose a method of inter-terminal transportation (ITT) using buffer space to solve the problem caused by inefficient ITT systems and presented a mixed integer programming (MIP) for the problem. The effect of using the buffer space was analyzed for various work volumes and capacity fluctuation ranges by applying the terminal congestion pattern and ITT vehicle in/out pattern based on the Busan New Port data.

As competition between universities intensifies due to the recent decrease in the number of students, it is recognized as an essential task of universities to predict students who are underperforming at an early stage and to make various efforts to prevent dropouts. For this, a high-performance model that accurately predicts student performance is essential. This paper proposes a method to improve prediction performance by removing or amplifying abnormal data in a classification prediction model for identifying underperforming students. Existing anomaly data processing methods have mainly focused on deleting or ignoring data, but this paper presents a criterion to distinguish noise from change indicators, and contributes to improving the performance of predictive models by deleting or amplifying data. In an experiment using open learning performance data for verification of the proposed method, we found a number of cases in which the proposed method can improve classification performance compared to the existing method.

The Transport policies in Korea have been planned and implemented as a part of a larger economy policy based on the achievement of economic growth. As a result, previous transport policies have been focused mostly on the supply of transport infrastructure. The average annual economic growth of six percent and a twelve percent growth in motor vehicles until the late 90s led to the acceleration of the imbalance between the supply and demand of infrastructure. As such, there is a need to establish an innovative transportation policy in order to increase national competitiveness and provide momentum for national growth in the Twenty one century. This research has developed strategies and policies based on interviews that were carried out with specialists in transport field. Moreover, some transport policies have been established for the year 2020 through the conducting of a survey. The survey was conducted by interviewing respondents on making the priority of transport policies. which was then analyzed using the Data Envelopment Analysis with ranked voting data. The results are as follows. The most urgent matter was considered to be the development of a inter-modal transport system, followed by an integrated service system for public transport, and the need to increase the competitiveness of the transport and logistics industries and to further transport safety. Meanwhile, the provision of transportation for disabled people as well as the elderly was considered to be less important in Korea than in welfare nations. This stems from the belief as further attention needs to be paid to the construction of a public transport system, the establishment of transportation networks construction in preparation for reunification and the North-East Asian era, as well as the privatization of the transport infrastructure.

Purpose: This study investigated medical accessibility on optical stores and ophthalmic clinics of Seoul Special City and six other metropolitan cities. Methods: By using a number of households, population, optician stores, ophthalmic hospitals, and real estate (apartments) standard market price of Seoul Special City and six other metropolitan cities provided by the Commercial District Information System (2016.6) of Small Enterprise & Market Authority, we analyzed the level of healthcare accessibility and business area zones, Statistical analyses were performed with SPSS 18.0. Results: Inchon (household 2,227/population 5,723) had the highest household and population rate per optical store, and Gwangju (1,146/2,979) had the lowest. Gwangju (24,612/63,987) had the highest household and population rate per optical store, and Seoul (10,021/24,432) had the lowest. From the consumer and patient's point of view, lower household rate per optical store is a city with good accessibility to healthcare, but from an optical store and ophthalmic clinic's view, it will have great difficulty due to issues of competition. Conclusions: Consumers and patients should be the center of healthcare. A healthcare system that can provide smooth service anywhere anytime should be constructed. However, most metropolitan cities, including Seoul, have optical stores and ophthalmic clinics densely populated where profitability and liquidity are ensured and causing unbalanced distribution of healthcare. To solve such problems, we need proper distribution of optician stores according to the population proportion and industrial-educational research to find balance point of local healthcare.
