The urban housing market in Korea, especially in Seoul and the Capital region, has been revitalized with massive urban (re)developments and expanding real estate finance after the IMF crisis. This brought about a boom of housing price during the mid-2000s, which has been virtually stabilized by strong regulation policies of the previous government. But with impacts of the recent international financial crisis together with some inherent problems, the housing market of Korea faces with a worry of collapse in relation with the financial market volatility and the serious depression of real economy, and hence the current government attempts to implement strong deregulation policies on the housing market. In this paper it is argued that this kind of volatility of urban housing market seems to be caused by strategies of capital which involve continuous massive urban (re)development, residential segregation and appropriation of monopoly rent(or capital gain), and fictitious capitalization of real estates and integration of real estate market and financial market. In these reasons, the current tendency of urban housing price shows a slow downward, which seems to give the current neoliberal government a rationale for deregulation policies to prevent the downward tendency. But this paper suggests that such a slow downward of housing price shift would have positive effects on the housing market in particular and social and economic situations in general, and hence an alternative housing policy is required to realize such positive effects.

Recently, industrial locations have faced changing trends under the influence of emerging industries as well as advanced new technologies. So the purpose of this study is to analyze the spatial distribution and locational factors of biotechnology industry formed around the Seoul Metropolitan area and Daejeon city, both of which are centers of Korean biotechnology industry, and is also to identifytheir locational characteristics. Major results of this study can be outlined as follows: First, from the mid 1990' s to 2000, Korean biotechnology industry has rapidly developed owing to central and local governmental support policies and systems as well as changes in domestic economic environment due to Korean financial crisis. Secondly, it was found that spatial distribution of Korean biotechnology industry converged on the Seoul Metropolitan area till 1990, but shifted from there to Daejeon and Chungcheong area from 1990 to 2000. Particularly after 2000, positive local governmental efforts to attract biotechnology players have driven the spatial distribution of biotechnology industry to shift from Seoul Metropolitan area and Daejeon or adjacent area gradually to other profitable locations. In terms of locational factors, it was found that the locations of Korean biotechnology industry converged primarily on university or college campus and biotechnology venture center, particularly on locations adjacent to superhighway or expressway. Locational factors varied depending on region, industrial type and business growth phase. Therefore, it is advisable that our central and local government should make and implement practical and useful policies in favor of biotechnology business depending on region, industrial type, business growth phase, rather than depending on uniform locational policies.

This study examines American geography educators' familiarity and knowledge of Korea, their perception on sovereignty education, and their knowledge on Korea's sovereignty issues using the survey conducted at the annual conference of the National Council for Geographic Education (NCGE) in the United States in 2010 and 2012. This study also analyzes how much these knowledge and perception influence on values of sovereignty education and Korea's sovereignty issues and further investigates proper educational approaches on territorial issues in Northeast Asia. Knowledge on the geography of Korea of American geography educators is higher than their knowledge on Korean culture. Both experiences attending educational programs about Korea and visiting Korea further enhance their knowledge on the geography of Korea and Korean culture. They agree the importance of sovereignty education in geography education and believe that sovereignty education should promote students' sense of patriotism and encourage students to be global citizens who promote public interests. However, they value less on teaching on the economic value of their own country's territory and students' ability to understand territorial conflicts with other countries. American geography educators' perception on sovereignty education improves their familiarity with and knowledge of Korean territorial issues. This study identifies that providing opportunities to learn about Korea and Korean territorial issues can maximize geography educators' accessibility to Korean territorial issues, regardless of their interest in territorial issues. These findings help Korean government develops better strategies for formulating and implementing future international public relations practices for Korean territorial issues.

The commerce and industry of Busan was developed because of good geographical conditions with harbor. After passing its settling-down and diffusing time, Busan has grown in the trade city. Busan has lost the competitive power of the port city since 2000, because of the weakness of its economic power which is caused by the secession of manufacturing industry and the decrease of resident population and foreign tourist. In order to overcome these weaknesses, it is necessary for Busan to take the innovative strategy for the activation of marine tourism. This goal can be achieved by the strong quality of the port city, the coastal terrain, the traditional industry and the international traffic. The aim of this paper is to explore the Innovative Strategy for the activation of marine tourism in Busan and to suggest the following proposal. First, the government must decide the base of marine tourism under the geography viewpoint of the coast and sea, and develope tourism resources after analyzing the identity of marine tourism base. Second, the core part along the selected bases of marine tourism must be constructed the tourism terminal as the landmark of Busan in order to concentrate foreign tourist. Third, after each base of marine tourism must become the resort for tourists, they are able to experience the activity of marine tourism in this resort. Therefore, each base must be specialized. Fourth, each base must be connected with the route of marine tourism Fifth, in order to overcome the off-season of marine tourism, winter tourism goods such as skates, skis, artificial sea-bathing pool, artificial swimming beach, artificial sled, artificial rock wall of coast, hot spring resort of salt water are required to be developed in the center of marine tourism base.

A city is an ordinary space and a place of living that is directly related to our lives. An ordinary space is the total products of culture and the target of cultural representation. An aging residential area of a city reflects the ordinary lives of ordinary people along with its unique history; therefore, this place should not be seen only from an economic and political perspective. The Wausan area is a place that best maintains the characteristics and scenery of an aging urban residential area within Gwangju metropolitan city. Through research into this area, it is possible to discover the meaning and true value of an aging urban residential area such as the close relationship between ordinary culture and placeness, the creation factors and process of placeness of an aging urban residential area, and the authenticity of a particular place. This area is a modern residential area of today's ordinary people, created on a topography of hills and hilly areas along with a historical value of 400 years. It is based on the Gyeongyangyeok of the Joseon period. This place may be described as a space where the dailiness of ordinary people is alive based on its alleys and the unique scenery formed by its alleys and vegetable gardens. The authenticity deduced from such placeness is that an aging urban residential area is a place where communicative and considerate human life and a cultural diversity of an atypical nature are alive, a place where an environment and humans coexist in harmony, and a place where the communal dailiness of residents still exists.

This paper is to conceptualize the urban social circulation of water from the social constructivism and political ecology, and to analyze the history of development of social circulation of water, that is, the modernization process of water in Daegu. The development of social circulation system of water in Daegu can be divided into 4 stages, that is, the beginning stage of modernization of water mainly during the period of Japanese colonization, the take-off stage from the 1960s to the mid-1980s, the stage of reflexive modernization from the late 1980s to the 1990s, and that of neoliberalization of water since the 2000s. It can be seen that the development of social circulation system of water in Daegu has contributed the increasing urban population and economic development, especially supporting the spatial expansion of the city and the way of modern way of urban life. But the social circulation system of water in Daegu seems to meet with a lot of problems such as relocation of the water intake station, over-equipment of filtration plants, distrust on tap water, inequality of water use, readjustment of water charge, liquid waste from industrial complexes within the urban area, creative destruction of waterfront environment, and privatization of water.

The genetic algorithm (GA) and branch and bound (B&B) methods are the useful methods of searching the optimal project combination (combinatorial optimization) to maximize the project effect considering the budget constraint and the balance of regional development with regard to the Urban Regeneration New Deal policy, the core real estate policy of the Moon Jae-in government. The Ministry of Land, Infrastructure, and Transport (MOLIT) will choose 13 central-city-area-type projects, 2 economic-base-type projects, and 10 public-company-proposal-type projects among the numerous projects from 16 local governments while each government can apply only 4 projects, respectively, for the 2017 Urban Regeneration New Deal project. If MOLIT selects only those projects with a project effect maximization purpose, there will be unselected regions, which will harm the balance of regional development. For this reason, an optimization model is proposed herein, and a combinatorial optimization method using the GA and B&B methods should be sought to satisfy the various constraints with the object function. Going forward, it is expected that both these methods will present rational decision-making criteria if the central government allocates a special-purpose-limited budget to many local governments.

As regional air pollution gets worse by the sulfur oxides emitted from various types of vessels passing through the many countries, the International Maritime Organization establishes the emission control areas and regulates sulfur dioxide in those areas. In order to satisfy these regional regulations, the fuel selection method and the exhaust gas post-treatment device are applied to the ships. Due to the economic reasons, the post-treatment method of exhaust gas for reducing the amount of sulfur oxides discharged is mainly preferred. The scrubber which is dominantly used in the ships are the spray type system where the sprayed liquid drops used for capturing the soluble sulfur dioxides in the exhaust gas. The performance of the spray type system depends on the size distribution of the sprayed droplets. In order to evaluate this performance, we designed counterflow type scrubber and cyclone scrubber and evaluated the desulfurization efficiency and the amount of droplet evaporation according to the size of each droplet by using computational fluid dynamics. The Eulerian-Eulerian analysis method was used because the scrubber had a gas-liquid two-phase flow inside the scrubber. When the diameter of the droplet was $100{\mu}m$, $300{\mu}m$, $500{\mu}m$ and $700{\mu}m$. As a result, both of scrubbers showed high desulfurization efficiency and low evaporation amount at $500{\mu}m$ and $700{\mu}m$.

The amount of data is increasing through various IT devices in a hyper-connected society where the 4th revolution is progressing, and new value can be created by analyzing that data. This paper was collected total 1,526 articles from 2017 to 2019 in central magazines, economic magazines, regional associations, and major broadcasting companies with the keyword "(East Coast Tourism or East Coast Travel) and Gangwon-do" through Bigkinds. It was performed the topic modeling using LDA algorithm implemented in the R language to analyze the collected 1,526 articles. It was extracted keywords for each year from 2017 to 2019, and classified and compared keywords with high frequency for each year. It was setted the optimal number of topics to 8 using Log Likelihood and Perplexity, and then inferred 8 topics using the Gibbs Sampling method. The inferred topics were Gangneung and Beach, Goseong and Mt.Geumgang, KTX and Donghae-Bukbu line, weekend sea tour, Sokcho and Unification Observatory, Yangyang and Surfing, experience tour, and transportation network infra. The changes of articles on East coast tourism was was analyzed using the proportion of the inferred eight topics. As the result, the proportion of Unification Observatory and Mt. Geumgang showed no significant change, the proportion of KTX and experience tour increased, and the proportion of other topics decreased in 2018 compared to 2017. In 2019, the proportion of KTX and experience tour decreased, but the proportion of other topics showed no significant change.
