The regulation of HNS has been intensified by the international trends including OPRC-HNS Protocol and '96 Convention which was driven by the high amounts of cargo. Due to the characteristics of HNS that would possibly bring potential damage with personnel and assets, effective management and prompt actions are required definitely. In order to respond effectively against HNS accidents, Korea Coast Guard (KCG) is in the process q development of HNS accident response manual and information system which allows On-Scene Coordinator(OSC) and personnels for rescue including an information for hazardous materials, sensitive area to be affected, solution methods and more. Furthermore, KCG is also building up establishment of national and local contingency plans for HNS in accordance with OPRC-HNS Protocol. It is also advised to proceed for the government to solve the anticipated obstacles that include protection equipments to get close to the site, experts allowing to manage accidents and organizations specialized for overall HNS related matters. The proposed issues described above are planned to conducted on basis of government.

The oceans are the largest body of water geographical unit in the earth. In accordance with the general said of the international law, countries on the international law must have four elements: 1) settled residents; 2) determined territory; 3) a certain degree of government organizations; 4) the sovereignty. The country's basic rights are: 1) the right to independence; 2) the right to equal; 3) the right to jurisdiction; 4) the right to self-protection. UNCLOS as the only one of the "Constitution of the Earth" on the earth, the implementation of its entry into force make about 1/3 of the world's oceans should be assigned to the coastal states, in the use and management of ocean gave the coastal states the center jurisdiction, the coastal states' jurisdiction sphere had been expanded, the power comparison among all countries in the world had new changes. The ocean territory, like the land territory, is the most major material condition of a country. The ocean's strategic status is extremely important, is the important stage of the international political, economic and military struggle, there are many disputes about the rights and interests, resources and the development and utilization on the oceans. To resolve these disputes is bound to depend on a strong comprehensive national strength, including politics, economy, science and technology, as well as the powerful marine force, in which maritime police plays an important role.

In 2007, Long-Term Care Insurance Law was enacted to share the family burden of caring for the elderly who are unable to perform every day living activities due to their old age and chronic diseases such as senile dementia, diabetes mellitus, stroke and more. Backed by this law, since 2008, care workers have been sent to the elderly care centers or each elder's home to help them not only with their recovery from illnesses, but also with general activities from dressing, eating, bathing, walking even to toileting. However, according to the recently released survey by National Human Rights Commission, it has been found that the caring workers are in a very poor working condition including low income, abused blanket wage system, shortage of welfare services, extra works and even sexual harrassment. It is becoming an important issue due to fast-ageing population, the fact that the care workers have had experiences of violation in their right of labor while they are at work needs to be carefully treated. In that sense, this article presents some difficulties the caring workers face and proposes effective ways to solve these problems through the perspective of human rights and human labor rights based on the report written by National Human Rights Commission. In short, for this law to function properly and to boost the worker's capability of providing better services to beneficiaries, followings can be good answers - enhanced management and supervision on caring plans and care centers, providing immediate counselling and protection for victimized care givers, training courses offered to promote service receiver's sincere respect and strengthened awareness upon care givers.

For an efficient and reasonable management scheme for protecting the soil environment, a soil ecological risk assessment (ERA) method should be developed prior to utilization, based on the contemporary uses and situations of each country. The Korean environmental policy focusing on soil protection is currently accelerating the development of the soil ecological risk assessment method. The soil ERA requires toxicological data on various trophic levels in the soil environment, and ultimately uses PNEC (Predicted No Effect Concentration), which is derived from collected toxicological data. Therefore, test species that are used to generate toxicity data are essential for conducting reliable ERA. This study aimed to select domestic test species for potential use in a reliable Korean ERA. Copper (Cu) and Nickel (Ni) were identified as target substances, with toxicity data (Cu, Ni) and standard test methods being collected to determine candidate species. The candidate species were first classified by soil trophic level, and then sorted into final domestic species. Forty out of 166 domestic species were determined as potential standard test species, whereas 17 out of 120 species were determined as potential Cu and Ni test species. Finally, this study presented potential soil test species based on the characteristics of the domestic soil environment, and established a preliminary step toward developing a reliable Korean soil ERA method.

The levels of psychosocial stresses and fatigue of firemen were analyzed to reveal the various factors related to them. The self-administered questionnaires were performed to 262 firemen ill Cheonsju City. In terms of various levels of psychosocial stresses, 12.2% were under potential stresses, 87.8% were under high-level of stress, but healthy group was not found. The levels of fatigue symptoms divided by the median of total scores was 51.1% of low levels, and 48.9% of high levels. Multiple stepwise analysis revealed that the factors or influence on psychosocial stresses with explanatory powers of 11.5% included subjective health status, job satisfaction, job demand and alcohol drinking habits. The factors of influence on fatigue symptoms with explanatory powers of 9.0% included subjective health and regular exercises. The study results indicate that the level of stress or fatigue is so complicatedly influenced by variable factors. Thus the effective strategy for stress and fatigue reduction among firemen should include additional programs focusing on health promotion.

The Korea Radioactive Waste Agency (KORAD) has developed a concrete cask for the dry storage of spent nuclear fuel that has been generated by domestic light-water reactors. During long-term storage of spent nuclear fuel in concrete casks kept in dry conditions, the integrity of the concrete cask and spent nuclear fuel must be maintained. In addition, the radiation dose rate must not exceed the storage facility's design standards. A suitable shielding design for radiation protection must be in place for the dry storage facilities of spent nuclear fuel under normal and accident conditions. Evaluation results show that the appropriate distance to the annual dose rate of 0.25 mSv for ordinary citizens is approximately 230 m. For a $2{\times}10$ arrangement within storage facilities, rollover accidents are assumed to have occurred while transferring one additional storage cask, with the bottom of the cask facing the controlled area boundary. The dose rates of 12.81 and 1.28 mSv were calculated at 100 m and 230 m from the outermost cask in the $2{\times}10$ arrangement. Therefore, a spent nuclear fuel concrete cask and storage facilities maintain radiological safety if the distance to the appropriately assessed controlled area boundary is ensured. In the future, the results of this study will be useful for the design and operation of nuclear power plant on-site storage or intermediate storage facilities based on the spent fuel management strategy.

Fungicide resistance study in Korea is still in its infancy, and most of those resistance studies are largely limited to newness of the detected resistant strains. In future, detection of fungicide-resistant strains has to be based on sensitivity distribution of pathogen populations to certain fungicides, and standard levels of certain fungicides for resistance should be determined under the basis of this data. Most of the early research on fungicide resistance in Korea has overlooked this point, and resulted in inconsistency and confusion for monitoring sensitivity shift of pathogen population among individual researchers. Fungicide resistance detected in vitro tests has to be documented in field trials by examining control efficacy against resistant and wild-type pathogen populations. Resistance detection in wife has to be correlated with lower activity in practice. Using this process, fungicide resistance will have a practical meaning. Fitness evaluation of resistant strains for survival is, in particular, of importance to determine the future stability of the resistance in the pathogen population. In fields, sensitivity change of pathogen populations should be carefully monitored with and without fungicide selection pressures to establish long-term management strategies against fungicide resistance. It is becoming an urgent task to provide information through research for designing and implementing successful counter-measures against fungicide resistance problems in Korea.

In recent studies, $PM_{2.5}$ has been reported to be more harmful to human health than $PM_{10}$ because it penetrates more deeply into the lung. We estimated $PM_{2.5}$ related health benefits in Seoul from implementing the World Health Organization (WHO)'s guidelines (annual average $10{\mu}g/m^3$, 24-hour average $25{\mu}g/m^3$) and U.S. Environmental Protection Agency (EPA)'s National Ambient Air Quality Standard (annual average $15{\mu}g/m^3$, 24-hour average $35{\mu}g/m^3$). U.S. EPA's Environmental Benefits Mapping and Analysis Program was utilized for the analysis. It was predicted that the attainment of the WHO annual guideline and U.S. EPA's annual standard, relative to the concentration in 2006, would result in reduction of 2,333~2,895 premature deaths and 1,703~2,121 premature deaths, respectively. If the WHO and EPA's daily standard for $PM_{2.5}$ are attained, 1,211~1,394 and 1,012~1,165 premature deaths could be avoided, respectively. Sensitivity analyses indicated that the estimates were robust regardless of air quality simulation methods for attaining the $PM_{2.5}$ goals. This study provides a quantitative approach to evaluate health risks from air pollution as well as to assess the potential health benefits of improving atmospheric $PM_{2.5}$ concentration. Even considering the intrinsic limitations and uncertainties of the analysis, it is an important information to rationalize the enforcement of $PM_{2.5}$ management policies and measures in Seoul, Korea.

Private security industry in South Korea has rapidly been growing in recent years. However, such a rapid growth is being criticized for its focus on external results, which has produced a number of problems. The continued growth of private security industry can be only based upon substantive and qualitative development. In this aspect, it is necessary to consider the global trends of the private security industry, particularly the recent trends of the U. S. security industry which has led the global security industry. This is because the recent trends of the U. S. private security industry would guide the future direction of the private security industry in South Korea. The U. S. private security industry has been replacing the role of law enforcement agencies including the police, from crime prevention to investigation and disaster management, not to mention asset protection and loss prevention. The recent trends of the U. S. security industry appears to be summarized by such characteristics as variety, specialty, and integration, which might account for the structural problem of the private security industry in South Korea. In short, the substantive and qualitative development of the private security industry in South Korea should be accomplished by strengthening its specialty and integration, and also widening its variety.
