Recently, one of the critical issues in Korea is the huge debt and future role of Korea Land and Housing Corporation. In this regards, the purpose of this study is to get implications from other public housing agencies in Asian countries such as UR of Japan, HDB of Singapore and HA of Hongkong. The changes of housing policy since 1960s, business and financial structure of housing agencies in each nation are investigated and compared. As a result, some policy directions can be proposed as follows : review of current mass housing program, relaxing qualifications for public rental housing, promotion of urban renewal projects, reinforcing cooperation with private sector and local governments, more government's support to LH's financing and loss from businesses for public interests and re-evaluation of LH's debt. The contribution of this study is that suggestions to improve housing policy and to alleviate financial problem of LH are based on the actual conditions of public housing agencies in Asian countries where the housing policy implementation system is similar to Korea, not on the theoretical basis.

The indices to choose the object countries for developing overseas industrial park were developed and applied in this paper. The results are showing as follows. First, the Korean enterprises are branched out into total 128 countries as of the first quarter of 2010, and the 13 asian countries including China, Vietnam, Japan, and Hongkong shows the majority of precedence 20 countries among the reported during 1980-2010. Second, the 3 steps of selecting the principal region to branch out, establishing assessment indices and criteria, and choosing strategical target counties were developed to choose the countries for developing overseas industrial park. The 38 of 128 countries were selected where the GDP per capita is lower than Korea, and the local reports of incorporation during 2007-2010 are more than 10 times. Then, the 10 countries were excluded where the minimum wages during 2008-2009 are similar to Korean ($815/month). Consequently, the 28 countries including China, Vietnam, and Cambodia etc. were selected as the major target regions. Third, the indices to choose countries for developing overseas industrial park are classified into 5 categories-investment condition, labor market flexibility, potential market demand, population, changing rate of the reported number of manufacturing industry, and detailed indices for each category were selected, then the weight were given with the consideration of importance. Finally, Indonesia, Mongolia, and Uzbekistan were selected as the strategical target counties where acquire the high score in labor market flexibility and investment condition, relatively undeveloped, and friendly to Korea.

Creative industries and creative occupations have been attracting issues in recent years, in both policy and academic fields. Although no literature has yet made all-embracing definitions of creative sectors, it is important to measure creative workers who are contributing to the national economy. Since 2000, many countries including UK, France, Germany, Finland, Hongkong, US, Canada, etc. have tried to develop more refined mapping methodologies for measuring the creative economy. However we are lack of deep scrutiny in the criteria select which sector is creative or not, as well as in existing methodologies for measuring creative employment. This paper presents a creative mapping methodology, called 'Creative Trident' and criteria that can be applied to measuring the scale of creative employment in Korea. Using annual labor data from Statistics Korea and Ministry of Employment and Labor, this research found that creative employment in Korea amounts to 40,922 and 6.65% of total employment. Also the research found that there are many workers who are creatively occupied outside the creative industries, called embedded creative workers which are 248,445 and 33.5% of total creative employment. That means embedded workers take some large portion of all creative workers and are dispersed across all the sectors of the economy. The research demonstrates that creative trident can be useful to estimate the true size of creative employment in Korean and finishes with some academical and practical implications.

The purpose of this paper is to show the clustering trend and to choose the clustering ports for 3 Korean ports(Busan, Incheon and Gwangyang Ports) by using the self organizing maps based on neural network(SOM) and Tier models for 38 Asian ports during 11 years(2001-2011) with 4 input variables(birth length, depth, total area, and number of crane) and 1 output variable(container TEU). The main empirical results of this paper are as follows. First, clustering results by using SOM show that 3 Korean ports[Busan(26.5%), Incheon(13.05%), and Gwangyang(22.95%) each]can increase the efficiency. Second, according to Tier model, Busan(Hongkong, Sanghai, Manila, and Singapore), Incheon(Aden, Ningbo, Dabao, and Bangkog), and Gwangyang(Aden, Ningbo, Bangkog, Hipa, Dubai, and Guangzhou) should be clustered with those ports in parentheses. Third, when both SOM and Tier models are mixed, (1) efficiency improvement of Busan Port is greater than those of Incheon and Gwangyang ports. (2) Incheon port has shown the slow improvement during 2001-2007, but after 2008, improvement speed was high. (3) improvement level of Gwangyang port was high during 2001-2003, but after 2004, improvement level was constantly decreased. The policy implication of this paper is that Korean port policy planner should introduce the SOM, and Tier models with the mixed two models when clustering among the Asian ports for enhancing the efficiency of inputs and outputs.

Limit state design (LSD) and allowable stress design (ASD) are two main types of soil nailing design methodologies. In the LSD method, stability is determined by applying individual coefficients to ground strength, working load and etc. The ASD method calculates the safety factor and compares it with the minimum safety factor to determine the stability. The global design trend of soil nailing system is changing from the ASD method to the LSD method. The design method in Korea still adopts the ASD philosophy while others mostly do the limit state design. In this study, four soil nail design methods, 'FHWA GEC 7' in U.S. (2015), 'Clouterre' in France (1991), 'Soil nailing - best practice guidance' in U.K. (2005), 'Geoguide 7' in Hongkong (2008), and 'Design guide for slope in construction work' in Korea (2016) were applied to the evaluation of the stability and the results were analyzed comparatively in brief. It is revealed that the design method of 'the overall stability of soil nail walls' in Korea is the most conservative and next those by FHWA, Clouterre and CIRIA become more conservative in order. However, the difference of results obtained from FHWA and Clouterre is negligible. Also, this study found out that efforts to improve domestic design criterion are needed.

1997년 홍콩 가금시장에서의 H5N1 조류독감바이러스의 발병은 18명의 감염된 사람 중에서 6명의 사람의 생명을 앗아갔다. 이 사건은 조류독감바이러스가 매개체를 통하지 않고 닭에서 바로 사람에게 감염한 처음 있는 사건이다. 홍콩가금시장에서의 역학조사는 H5Nl과 H9N2 조류독감바이러스가 함께 공존한다는 것을 밝혔다. 가금에서는 H5N1과 H9N2 조류독감바이러스가 검출되었다. 우리는 H5N1 조류독감바이러스로부터 자을 방어하는데 H9N2 조류독감바이러스의 역할에 대해 연구했다. H5N1과 H9N2 바이러스의 혼합바이러스를 동시에 자에 접종하면 자은 생존하지 못했다. 그러나, H5N1 조류 독감바이러스감염 이전에 H9N2 조류독감바이러스를 감염한 닭들은 생존할 수 있었다 H9N2 조류 독감바이러스로 감염된 닭으로부터 얻어진 혈청은 H5N1 조류독감바이러스와 교차반응을 일으키지 않는다. H9N2 조류독감바이러스로 감염시킨 닭으로부터 얻어진 T임파구 또는 CD8 T임파구를 감염하지 않은 닭에 주입할 때 닭은 H5N1 조류독감바이러스로부터 생존할 수 있었다. 실험실외 킬러임파구실험은 H9N2 조류독감바이러스로 감염된 닭으로부터 얻어진 T임파구는 H5N1과 H9N2 조류독감바이러스로 감염된 목표세포를 동시에 감지했다. 게다가, 생체내 T임파구의 제거실험은 교차보호면역은 a/b TCR를 가진 CD8 T임파구가 중요한 역할을 하며, a/b TCR (Vbl)형의 T임파구가 목표세포를 감지한다는 것을 증명했다. H9N2 조류독감바이러스에 의한 방어면역은 시간이 지남에 따라 감소를 했고, 감염 100일까지 방어력을 나타냈다. 1997년 조류독감바이러스인 H5N1의 홍콩에서의 발병에 대한 풀리지 않은 것 중의 하나는 약 20%의 조류들이 매우 치사율이 높은 H5N1 독감바이러스를 가지고 있음에도 홍콩가금시장에서의 대부분의 닭들은 건강했다. 얻을 수 있는 정보에 따르면 대부분의 자들은 H5N1조류독감바이러스를 변으로 방출했고, 단지 두 곳의 가금시장에 있는 자들이 질병증상을 보였다. 홍콩가금시장에서 분리된 모든 H5N1 조류독감바이러스를 닭에 감염하면 100%의 치사율을 나타낸다. 바이러스 측면에서의 연구에 따르면, H9N2 조류독감바이러스는 홍콩가금시장에서 두 번째로 많이 분리되었다. H9N2 조류독감바이러스에 대한 연구에 따르면 세 가지 형이 홍콩가금시장에서 검출되었다. 1997년에 가장 많이 분리된 H9N2 조류독감바이러스는 PB1과 PB2가 A/Chicken/HongKong /156/97 (H5N1)과 유전적으로 유사한 A/HongKong/G9/97 (H9N2)형이다. A/Chicken/Hong Kong/156/97(H5N1)의 나머지 유전자는 A/Chicken/HongKong/739/94 (H9N2)와 A/chicken /Hong Kong/G23/97의 유전자와 비슷하다. 하나의 A/Quail/Hong Kong/G1/97은 Quail에서 분리되었고, 두 개의 A/Duck/Hong Kong/Y280/97 (H9N2)은 오리에서 분리되었다. A/Quail/Hong Kong/G1/97 (H9N2)의 6개의 내부유전자는 A/HongKon9/156/97 (H5N1)에 유사하나, A/Duck/ Hongkong/Y280/97 (H9N2)의 유전자는 A/HongKong/156/97 (H5N1)과 유사하지 않다. 킬러임파구는 바이러스로 감염된 목표세포를 MHC에 의존하여 파괴한다. 독감바이러스 특이 킬러임파구는 독감바이러스로 감염된 mice의 폐로부터 독감바이러스를 제거하는데 중요하다고 알려져 있다. 독감바이러스의 HA단백질은 특이 킬러임파구의 주요 목표항원 단백질이 아니다. 내부단백질인 nucleoprotein, polymerase (PB1 PB2, PA), Matrix protein, 그리고 비 구조단백질인 NS1에 대한 특이 킬러임파구의 반응이 사람과 mice에서 보고되었다. 독감바이러스에 대한 mice의 킬러임파구의 인식영역은 제한되어 있다고 알려져 있다. 많은 mice MHC 1은 독감바이러스 단백질의 킬러임파구의 epitope를 표현하지 못한다. 사람 기억킬러임파구는 다양한 종류의 독감바이러스의 단백질을 인식한다고 알려져 있다. 지금까지, 닭에서의 독감바이러스의 킬러임파구에 대한 연구는 되지 않았다.
