With an entering into force of OPRC-HNS started in June 14th 2007, establishment of response system in a nationwide scale to take care of accidents is required to respond rapidly and effectively. This necessities drove us to analyze national contingency plan for chemicals including national response system against accidents, which is in operation in the US. Main characteristics of the system are well described as an integrated incident command system with a cooperation of responsibilities facilities, manpower, and technical support. In addition, state anψor local authorities tend to have responsibilities on management of disaster with its response activities. Polluters are also charged to pay expenses 3 times expensive provided state or local authorities are conducted. In general, response activities are conducted by private sectors. However, the government will take action with Superfund if the response capacity is over than the polluters can. However, safety are regarded as a primary factor to be considered in the response activities, and try not to recover any pollutants. Personals belonging to USCG and EPA are required to complete specialized courses to promαe professional skills, and are also welcomed to participate in "certification program"

Socioeconomic status in this county progressed rapidly, this has brought about many changes in health care fields, namely, pattern of disease prevalence and morbidity, increase of the aged people, and also availability of health care in rural areas. According to the utilization study of medical care, it showed that the oriental medicine is used for the treatment of lasted chronic disease not the minor and common diseases which is quick in its effect. Particularly, in rural areas. prevalence of chronic disease is higher than that in urban areas. Although the health cafe need of the oriental medicine is high in rural areas, the distribution of manpower and facilities is lower than that in urban areas. Therefore the government has planned to implement the demonstration project for the oriental medicine at the designated 3 health centers in rural areas. The purpose of this study was to collect the utilization level of oriental medical care of the people in rural areas. To meet the purpose of this study, patient interview were applied. 790 patients visited to health center in project areas were selected and analyzed by experienced interviewers from 2 April to 21 April 1990. The major findings of this study were as follows ; 1) Of the 790 patients, 32.6 percent of the respondents had experience of using the oriental medicine. As for the utilization by age and sex. 54.8% of those was female and 70.7% was 40 years of age and more. 2) Reaction to the question of educational achievement showed that on schooling and primary school graduates accounted for 63.1%. 3) The most user of oriental medicine resides in country level, where the health center is located, and 80 percent of those users resides within 10Km. 4) More than 50% of the total was the chronic diseases which lingered for more than 3months. 5) 32.6 percent of the total cases used the oriental medicine. 61.2% among those was treated by oriental medical care hospital and 38.8% by oriental drug dispensaries etc. 6) The contont of oriental medical care varied ; 50.1% for prescription of herb drugs for treatment, 25.1% for health maintenance and 23.9% for acupuncture, moxibustion etc. 7) As for the motivation for using the oriental medicine. 56.6% of the respondents was for treatment of diseases and 27.9% wes for strengthening the physical weakness. 8) As for the effectiveness of the oriental medicine. 70.3% of the total cases satisfied with that treatment and 84.2% of the total cases will use the oriental medicine when is provided by health center.

The steel cargoes as the core raw materials for the manufacturing industry have important roles for increasing the handling volume of the port. In particular, steel cargoes are fundamental to vitalize Port of Incheon because they have recognized as the primary key cargo items among the bulk cargoes. In this respect, the IPA(Incheon Port Authority) ambitiously developed the port complex facilities including dedicated terminals and its hinterland in northern part of Incheon. However, these complex area has suffered from low cargo handling records and has faced operational difficulties due to decreased net profits. In general, the import and export steel cargo volumes are sensitively fluctuated followed by internal and external economy index. There is a scant of research for forecasting the steel cargo volume in Incheon port which used in various economy index. To fill the research gap, the aim of this research is to predict the steel cargoes of Port of Incheon using the well established methodology i.e. System Dynamics. As a result, steel cargoes volume dealt with in Incheon port is forecasted from about 8 million tons to about 10 million tons during simulation duration (2011-2020). The Mean Absolute Percentage Error (MAPE) is measured as 0.0013 which verifies the model's accuracy.
PURPOSES : Daejeon is basically divided into an old downtown and a new downtown, and the recent relocation of the Chungcheongnam-do Provincial Government of Republic of Korea from the old downtown and the opening of governmental buildings in the new downtown as well have made this new downtown only densely populated with industrial and business facilities. Such changes in the downtowns have promoted the conditions of the new downtown while, consequently, dragging down the old downtown. Out of concern for those unbalanced developments of the two downtowns, Daejeon is now carrying out several city projects to revive the old downtown. In the light of that, as a part of the project to promote the old downtown, this study aims to conduct an evaluation on landscape of the culture and arts street in Daeheungdong which was built upon those ideas of a theme street project by Daejeon. METHODS : Based on the findings from the questionnaire not only on the components that would design the streetscape of the culture and arts street but also on the public satisfaction with the streetscape, the study defined how those changes in the components affect emotional factors of the pedestrians. In order to achieve the research goal, the study made changes in D/H ratio of the street structural components as well as the roadside trees. In terms of the questionnaire method, the study used the SD scale, and proceeded with its investigation through the frequency analysis, the principal component analysis (the factor analysis) and the structural equation model. RESULTS : According to the results from the factor analysis and the regression analysis, of those three factors, such as the openness, the comfortable sensation and the safety, the openness followed by the comfortable sensation and the safety was determined to have the most positive influence on the total satisfaction. The structural model analysis reported that the D/H and the structural components of the roadside trees and planting have a positive effect on the emotional image, and this emotional image also appeared to be positively related to the total satisfaction. CONCLUSIONS : This study looked into how the changes in the street structural components of the culture and arts street in Daeheungdong would affect the satisfaction with the streetscape, and finally confirmed that the D/H and the planting are what would have a positive effect on this satisfaction. What has been learned from this study will be the basic data to figure out how to promote and improve the culture and arts street in Daeheung-dong as this data will also help designing and developing of those specialized streets in other regions.
Island regions suffer from a shortage of health care in part because they are less developed, they cover a widespread area relative to the population, and due to transportation barriers. The purpose of this study was to assess the level of illness and the magnitude of medical care utilization, and to investigate the determinants of utilization in these area. The data were collected by means of a household survey conducted from February 16 to 25, 1987 on S islands which were selected in consideration of the size of the population, the distance from the main land, and the distribution of health care facilities. The household response rate was 89.1% (491 of 551 households), and 1971 persons were surveyed. The major findings of this study are as follows: 1) The morbidity rate of the island inhabitants was 27.7% during the two weeks, and 25.5 chronic illnesses and 9.1 acute illnesses per 100 persons, were noted. Differences in the magnitude of illness were statistically significant by sex, age, education, and family size. 2) The magnitude of total ambulatory carl utilization was 16.8 visits per 100 persons during the two weeks, which was less than that of other regions; and differences in the magnitude of total ambulatory care were statistically significant by sex, age, education, occupation, and family size. 3) Unmet needs were classified as 56.0% in chronic illnesses and 19.6% in acute illnesses; and differences in unmet needs were statistically significant by sex, age, education, occupation, income, and family size. 4) Statistically significant determinants in medical care utilization included the frequency of acute illness and chronic illness, and income in total utilization; the frequency of chronic illness and acute illness, and medical care insurance in physician visits. 5) According to the results of the path analysis, need factors had the greatest effect on utilization, and predisposing factors had more indirect effects through enabling or need factors than direct effects.
The numerous definition of terrorism is viewed as the use of force or violence by individual or group that is directed toward civilian populations and intended to instill fear as a means of coercing individuals or groups to change their political or social positions. Recently, the paradigm of terror has been developed as new terrorism motivated by 9. 11 terror in 2001. In these contexts, this study analyzed the case study of recent counter-terrorism of international events and suggested the policy implications. This study is split into four chapters. Chapter I is the introduction part. Chapter II introduces the reader to new terrorism theory, and Chapter III deals with the case study of the international counter-terrorism policy around the world, Chapter IV deals with the policy implications of the case study. The greater the political, economical and social advantages opening large international ceremonies, the larger the probability of being targets for terrorists and criminals. As terrorism is one of the important issue, the security problems at international ceremonies in Korea, rising country as political essence in Asian-Pacific region, become very important. With experienced know-hows against terror and preparations for security, local and central governments must promote the private security companies filling up vacancies of police and official security system and develop international ceremonies, rising high valuable industries in 21st century, with diplomatic efforts. International major events is the largest event related events with politics, economy, culture, and such large-scale events should be a comprehensive counterplan in the light of safety check for the location of a hazard and safety check of facilities in and out, attendance on athlete and visitor and escort of VIPs.

In 2016, the IMO's new rules for an 80% reduction in NOx emissions in newly built ships will necessitate the use of LNG as a clean fuel. So far, the developed European countries have led the development of LNG bunkering ships and related facilities. An LNG bunkering system stores LNG in a horizontal or vertical IMO "C"-Type tank insulated with perlite powder, and a vacuum in the annular space between the double walls, like the cryogenic liquid nitrogen tank. Current storage tanks have high heat leakage, evaporating over 2.0% daily, and are difficult to build with the required vacuum. A more efficiently insulated storage tank could reduce the evaporation rate. This research carried out thermal analysis on a new effective insulation method that separates high vacuum in the annular space between two tanks with a solid insulation material, such as urethane foam, lining the outer vessel. This highly efficient insulation system obtained an evaporation rate of 0.03% per day under a $10^{-3}torr$ vacuum, and an evaporation rate of 0.11% at $10^{-45}torr$. Even if the space loses its vacuum, the new insulation system showed a lower evaporation rate of 4.12% than the present perlite system of 4.9%. This newly developed tank can increase the efficiency of LNG storage tank and may help keep LNG bunkering systems safe.

It is necessary for managing a perfect process for degasing aluminum molten metal according to the increase of a grade of aluminum and its alloy products. There are some methods that have been used to manage a degasing process in recent years, such as an injection method that uses aluminum molten metal powder and chemicals supplier and input method that supplies argon and nitrogen, or chlorine gas by using a gas blow-tube. However, these methods show some problems, and it shows that it is a difficult process to handle. pollution due to the producing a lot of toxic gases like chlorine and fluoride gas. irregular effects, and lowering work efficiency due to the excessive processing time. The problems that are the most fatal are the producing a lot of sludge due to the reaction of aluminum molten metal with chemicals. loss of metals, and decreasing the life of refractory materials. In order to solve these problems. this paper develops a technology that is related to aluminum continuous casting molten metal and monolithic degasing apparatus. A degasing apparatus developed in this study improved the exist ing methods and prevented environmental pollution wi th smokeless. odor less, and harmlessness by using a new method that applies argon and nitrogen gas in which the methods used in the West and Japan are eliminated. The developed method can significantly reduce product faults that are caused by the production of gas and oxidation because it uses a preprocessed molten metal with chemicals. In addition. the amount of the produced sludge can also be reduced by 60-80% maximum compared with the existing methods. Then. it makes it possible to minimize the loss of metals. Moreover. the molten metal processing and settling time is also shortened by comparing it with the existing methods that are applied by using chemicals. In addition, it does much to improve the workers' health, safety and environment because there is no pollution. The improvement of productivity and prevent ion effects of disaster from the results of the development can be summarized as follows. It will contribute to the process rationalization because it does not have any unnecessary processes that the molten metal will be moved to an agitator by using a ladle and returned to process for degasing like the existing process due to the monolithic configuration. There are no floating impurities due to the oxidation caused by the contact with the air as same as the existing process. In addition. it can protect the blending of precipitation impurities. Because it has a monolithic configuration. it can avoid the use of additional energy to compensate the temperature decreasing about 60t that is caused by the moving of molten metal. It is not necessary to invest an extra facilities in order to discharge the gas generated from a degasing process by using an agitator. The working environment can be improved by the hospitable air in the factory because the molten metal is almost not exposed in the interior of the area.
