In recent years, there is growing concern about the potential use of biological agents in war or acts of terrorism accompanied an increased realization that rapid preparedness and response are needed to prevent or treat the human damage that can be caused by these agents. The threat is indeed serious, and the potential for devastating numbers of casualties is high. The use of agents as weapons, even on a small scale, has the potential for huge social and economic disruption and massive diversion of regional and national resources to combat the threat, to treat primary disease, and to clean up environmental contamination. Biological weapons are one of weapons of mass destruction (or mass casualty weapons, to be precise. since they do not damage non-living entities) that are based on bacteria, viruses, rickettsia, fungi or toxins produced by these organisms. Biological weapons are known to be easy and cheap to produce and can be used to selectively target humans, animals, or plants. Theses agents can cause large numbers of casualties with minimal logistical requirements (in wide area). The spread of disease cannot be controlled until there is awareness of the signs of infection followed by identification of agents; and if the organism is easily spread from person to person, as in the case of smallpox, the number of casualties could run into the tens of thousands. Biological weapons could be used covertly, there can be a lot of different deployment scenarios. A lot of different agents could be used in biological weapons. And, there are a lot of different techniques to manufacture biological weapons. Terrorist acts that make use of Biological Agents differ in a number of ways from those involving chemicals. The distinction between terrorist and military use of Biological Weapon is increasingly problematic. The stealthy qualities of biological weapons further complicate the distinction between terrorism and war. In reality, all biological attacks are likely to require an integrated response involving both military and civilian communities. The basic considerations when public health agencies establish national defence plan against bioterrorism must be 1) arraying various laws and regulations to meet the realistic needs, 2)education for public health personnels and support of concerned academic society, 3)information collection and cooperative project with other countries, 4)Detection and surveillance(Early detection is essential for ensuring a prompt response to biological or chemical attack, including the provision of prophylactic medicines, chemical antidotes, or vaccines) and 5) Response(A comprehensive public health response to a biological or chemical terrorist event involves epidemiologic investigation, medical treatment and prophylaxis for affacted persons, and the initiation of disease prevention or environmental decontamination measures). The purpose of this paper is providing basic material of preparedness and response for biological terrorism in modern society.

This study is to analyze the existence of the real buffer effect that reflects the effect of beginning-of-period inventory stocks effect on the demand for fixed investment, and the financial buffer effect indicates the substitution effect between end-of-period inventory stock and the source of financing for fixed investment. I use panel data of 361 Korean listed non-financial firms during 1990-2003. After the crisis, it also observed whether the relationship between inventory stocks and fixed investment has altered or not. I review the theoretical connection between inventory stock and fixed investment through the paper by Bo(2004) and estimate the investment model by the method of GMM-SYS. The results show negative relation between end-of-period inventory stock and fixed investment in the whole period and each period classified, also it confirms that the relation between fixed investment and end-of-period investment is significantly negative. It can be interpreted through two aspects that firms not only use inventory stock as a buffer in response to unexpectedly high demand, but also utilize inventory stock as a source of financing for fixed investment. The results imply that firm's decision-making is much correlated with production-and-inventory stock adjustment, decision-making about fixed investment, and decision-making about financial affairs.

There are about 5,300,000 overseas Koreans in the world. This is about 11.8 percent of the total population of the Korean peninsular. They reside in more than one hundred nations. This exodus occurred due to forced emigration, escape from oppressive regimes, and economic opportunity. Most of them are living in the four regions, that is, China, Japan, America, and Central Asia. The purpose of this paper is to examine the pattern of Korean migration to overseas and to compare the life style of overseas Koreans. The data are taken from a sample survey, which was conducted in China, Japan, America, and Central Asia. A total of 300 respondents were interviewed in each country. The result shows that there are some differences in the lives of overseas Koreans. For example, the Koreans in Central Asia may have suffered the greatest hardship, the similar case was found in the Koreans in China. By contrast, the issue of ethnic conflict becomes the most serious problem in the Koreans in Japan. This study also shows many aspects of common Korean heritage, that is, hard work, diligence, and high level of education. In addition, the study indicates that overseas Koreans are trying to retain Korean traditional values and relationships in their families.

Purpose - This study aims to (a) analyze local citizens' perception of a local company, the Gwangyang Steel and Iron Company (GSIC); (b) compare the perception toward the local company with that of national citizens' perceptions towards many other unspecified companies, which were surveyed biannually by The Korea Chamber of Commerce and Industry (KCCI); and (c) analyze how such companies evaluate perceptions towards them, in relation to citizens' socioeconomic position, such as their education status. Research design, data, methodology - The data were collected using a questionnaire, which was given to a sample of local citizens in cities. To test the hypotheses, factor analyses, a t-test, and an ANOVA were conducted. The total number of respondents was 1798. The data gathered from the respondents of the sample were analyzed using SPSS Win 19.0 software. Perception towards the company was evaluated on the corporate favorite index (CFI). The CFI index shows how positive citizens feel towards a company. It is calculated using five leading factors, consisting of the following: contribution to the economy, productivity, international competitiveness, social contribution, and ethical management. The higher the level of positive feelings exhibited, the closer the index will come to 100. Results - As a result of the analysis, the CFI index towards the GSIC stood at 67.3. The CFI index towards the company is 16.5 points higher than that of the index towards the many other unspecified companies, which were surveyed by the bi-annual KCCI study in the first half of 2011. The other five indexes stood as follows: contribution to the economy, productivity, social contribution, and ethical management was 69.2, 71.2, 64.6, and 58.6, respectively. These indexes are 18.3, 4.6, 27.6, and 35.6, respectively, higher than those found by the KCCI study. However, international competitiveness is 73.0 (9.8 points lower than that of the KCCI study). This survey thus shows that the CFI of the local citizens towards the global company GSIC is very high when compared with the CFI index towards the many other unspecified companies that was determined by the KCCI survey. Conclusions - This survey shows that local citizens have high expectations of economic activity, increasing working opportunities, and regional cooperation projects from the local company, GSIC. In addition, the CFI index towards GSIC evaluates results depending on the respondent's relationship with the company, and their educational status. Respondents, whose family or relatives were working as employees of GSIC, have relatively positive perceptions of GSIC, and respondents with a relatively higher educational status also share positive perceptions. Local citizens expect the profit-making of the company to operate in accordance with management activities, and at the same time, they expect that the wealth generated by the company will return to wider society.

Background: The geographical origin of Panax ginseng Meyer, a valuable medicinal plant, is important to both ginseng producers and consumers in the context of economic profit and human health benefits. We, therefore, aimed to discriminate between the cultivation regions of ginseng using the stable isotope ratios of C, N, O, and S, which are abundant bioelements in living organisms. Methods: Six Korean ginseng cultivars (3-yr-old roots) were collected from five different regions in Korea. The C, N, O, and S stable isotope ratios in ginseng roots were measured by isotope ratio mass spectrometry, and then these isotope ratio profiles were statistically analyzed using chemometrics. Results: The various isotope ratios found in P. ginseng roots were significantly influenced by region, cultivar, and the interactions between these two factors ($p{\leq}0.001$). The variation in ${\delta}^{15}N$ and ${\delta}^{13}C$ in ginseng roots was significant for discriminating between different ginseng cultivation regions, and ${\delta}^{18}O$ and ${\delta}^{34}S$ were also affected by both altitude and proximity to coastal areas. Chemometric model results tested in this study provided discrimination between the majority of different cultivation regions. Based on the external validation, this chemometric model also showed good model performance ($R^2=0.853$ and $Q^2=0.738$). Conclusion: Our case study elucidates the variation of C, N, O, and S stable isotope ratios in ginseng root depending on cultivation region. Hence, the analysis of stable isotope ratios is a suitable tool for discrimination between the regional origins of ginseng samples from Korea, with potential application to other countries.

Systematic and efficient forestry management is required because of the long-term low profitability of timber production and forest products. In this situation, non-timber forest products can be the solution to secure stable sources of income for workers in the forestry field. However, the existing studies for non-timber forest products focus on effective production and economic analysis and provide plans for increasing the income and improving the marketing system. Therefore, this research intends to analyze the spatial distribution as well as quantitative concentration of non-timber forest production. To achieve this goal, this study examined the regional concentration and dispersion of non-timber forest production in 2001, 2007, and 2014 using the coefficient of localization(CL) and location quotient(LQ) and investigated the change in spatial distribution using spatial statistics. The production of chestnuts generally showed a concentrated pattern in 2014 based on the outputs of the CL and LQ, but the result of spatial autocorrelation indicated a decrease in the spatial concentration. In addition, astringent persimmon showed more concentration from the output of CL than oak mushroom, but Moran's I suggests the opposite. Therefore, it is necessary to examine the spatial distribution to understand and improve the marketing system and intensify the production of forest products.

The purpose of this study is to prove double faced heterotopiatic placeness of North Korea which can be highlighted to one aspect through priming test. Korean-Americans are found to have a perception of North Korea as a closed society where political leader cult is practiced, Pyongyang as a display city. They have Christian nostalgia toward it as a place where Christianity was first introduced to. North Korea's heterotopiatic placeness is sharing the 5,000 years of history of the Korea peninsula on the one hand and being a closed dictatorship place on the other. North Korea is kept isolated and closed but has had a liminal space through the intentional open system like special economic zone. Pyongyang is the city for specific class where it shows the heterotopiatic character. Priming is found effective in Yeongbyun, a place of extreme mixtures placeness as being the hometown of the beloved Korean poet Kim So-Wol and the site of nuclear weapon experiment but Korean-Americans have not found any priming effect regarding the Geumgang mountain tour. As to the Arirang performance, a man-made landscape expressing North Korea's sense of value and ideology, priming resulted in preference. This study raises the needs for understanding North Korea as a multifaced placeness and it can purposely be emphasized and changed to contribute the two Korea's unification.

This paper is to reconsider comprehensively and systematically major issues on transnational immigrants, increased rapidly since the beginning of the 1990s, and their impacts on socio-spatial changes in S. Korea. Foreign immigrants who have moved on the contexts of unevenness of globalization and advancces in transport & telecommunication technology on the global level and of economic development and shortage of cheap and unskilled workers have been distributed unevenly, concentrating on the Capital region and local areas with industrial complexes. Foreign workers seems to have some negative influences on regional economies in the long-term, though positive in the short-term. Domestic people seem to have an ambivalent attitude which accepts necessity of multi-culture, while simultaneously continues to be self-confident on ethnic homogeneity. The Korean government has launched multicultural policies for foreign immigrants by the mid-2000, but still continues some policies with assimilationism and differential exclusionism, marginalizing them socio-spatially, while lacking local government's policy and programmes. In conclusion, in order to resolve these problems and to transfer multicultural societal space of Korea, a geography of transnational migration which promotes especially discourse and policy with authentic multiculturalism, extending roles of local government, and ensuring glocal citizenships.

The growth and development of Gwangyang city was a result of the POSCO Gwangyang Works, and Gwangyang city is one of typical firm citys in Korea. The objective of this study is to identify and examine the change of migration and population structure in Gwangyang city from 2001 to 2010. Since 1981, total number of population of Gwangyang city increased from 78,478 in 1981 to 145,512 in 2010. The population structure by age was changed with population increase since 2001, and 30-40 aging group was 35% of total in 2010. During 2001-2010, the netmigraion showed -2,925 people, however, the number of inmigrants were overtaking the number of out-migrants since 2008. The most common reason of in-migrants was occupation(49.5%). Factors influencing Gwangyang City's population growth and oversupply are the location of POSCO Gwangyang Works and steel-related enterprises, opening and construction of Gwangyang container berth, the related development projects and establishment of Gwangyang Bay Area Free Economic Zone, and the local policies of Gwangyang City connected with these large-scale national projects. As a result, the number of manufacturing-related businesses increased due to various regional development projects conducted in Gwangyang City, and the growth of the business continued to increase due to the increase of younger people and births.

Domestric Construction & Engineering market has been long in recession due to the global economic crisis. Domestic construction industries consequently looks at overseas construction markets where relatively more construction projects are constantly required. In order to provide meaningful information for Korean engineering companies to keep the pace with the changes in the construction industry, various construction related date and statistics are analyzed. In addition, previous research from the related organizations and construction engineering companies are closely reviewed. Investigation of preliminary data and research have been conducted to draw remedies for their overseas expansion. Moreover, it is attempted to classify foreign markets as the Asia, Africa and etc. (Europe, North America/the Pacific and Latin America) to provide the list of first target countries and its regional market information focusing on their bidding system. This study had tried to show comparative analysis of different bidding procedures between Korea and the selected countries to suggest measures of improvements for the domestic bidding system. Finally, this study suggested policy recommendations to meet the requirement of bid qualification to advance the global market that was suggested with validated clustering bidding data.
