Purpose: This study was designed to identify knowledge, attitude, environment, and self-efficacy among perioperative nurses in terms of radiation protection and to describe those factors affecting radiation protection behaviors. Methods: The sample was comprised of 128 perioperative nurses who agreed to participate in this descriptive study. Data were collected from a self-administered questionnaire and were analyzed using the t-test, analysis of variance, Mann-whitney U test, Kruskal-Wallis test, Pearson's correlation, and multiple regression analyses. Results: Radiation protection behaviors were significantly different by participant's gender, length of career as a perioperative nurse, educational level and prior experience with radiation protection education. Radiation protection behaviors were significantly correlated with radiation protection environment and self-efficacy in terms of radiation protection behaviors. In the multiple linear regression models, radiation protection environment and self-efficacy on radiation protection behaviors were statistically significant predictors of radiation protection behaviors, which accounted for 50.3% of variance in dependent variable. Conclusion: This study concluded that radiation protective environment in operating room is important to promote radiation protective behaviors and radiation safety management program to enhance self-efficacy is highly recommended.

Background: Airborne radioactive particulate in many important nuclear facilities (particularly nuclear power plants) will have a strong impact on the relative public dose if they are released into the corresponding environment traversing the stack or vents. The radiation protection researchers have regarded the relative environment assessing and estimation of public doses. And the model of assessing impact of discharges radioactive substance to the environment have been recommended by many international organizations (e.g. IAEA) with the nuclear energy safety and radiation protection. Materials and Methods: This paper introduced the generic models that were suggested by International Atomic Energy Agency (IAEA), for use in assessing the impact of discharges of radioactive substances to the environment (e.g. IAEA Safety Report Series No.19). Results and Discussion: The writers of this paper, based on the recommend methods, assessed the discharge limits in some airborne radioactive substances discharging standards. The reasons that IAEA method are introduced are mainly the following considerations: IAEA is one of international organizations with some authorities in the nuclear energy safety and radiation protection; and, more important, the recommend modes are operational methods rather than the methods having little operations such as that have used by some researchers. Conclusion: It is wish that the introduced methods in this paper can be referenced in draft or revise of the standards related to discharges of radioactive substances to the environment.

Ships and offshore structures are exposed to harsh marine environments, and maintenance and repair are becoming increasingly important to the industry and the economy. The major corrosion phenomenons of metals and alloys in marine environment are pitting corrosion, stress corrosion cracking, crevice corrosion, fatigue corrosion, cavitation-erosion and etc. due to the effect of chloride ions and is quite serious. Methods of protection against corrosion can generally be divided into two groups: anodic protection and cathodic protection. Anodic protection is limited to the passivity characteristics of a material in its environment, while cathodic protection can apply methods such as sacrificial anode cathodic protection and impressed current cathodic protection. Sacrificial anode methods using Al and Zn alloys are widely used for marine structures and vessels intended for use in seawater. Impressed current cathodic protection methods are also widely used in marine environments, but tend to generate problems related to hydrogen embrittlement caused by hydrogen gas generation. Therefore, it is important to the proper maintenance and operation of the various corrosion protection systems for ship in the harsh marine environment.

The burial method has been generally used for the protection methods of submarine cable. Especially in Korea, various types of protection methods have been used according to fisheries and fishing implements. In these days, all the protection methods - burial, continuous concrete mattress, cast iron pipes, U-duct, concrete bags, rock berm, mortar bags and FCM(Flexible Concrete Mattress) are applied to the submarine cable, but these methods just focus not on the characteristics of ocean environment and the protection of environment but on the safety of submarine cable against the external damages. This research presents the protection methods of submarine cable according as the characteristics of ocean environment - external damages, depth of water, seabed condition and the protection of environment.

It is a common and prevailing Construction that recent environmental problems such as earth's warmer climate and depletion of ozone layers can never be solved by the efforts of any one nation. That is why the international conventions have been held more often lately in order to discuss the matter of environment protection and there has been increased tendency of using economic activities of any nation especially their international trades as means for achieving the purpose of environment protection. Furthermore, there is an ample possibility for the advanced countries to use the regulatory restrictions for environment protection as an another measure of none-tariff barrier against countries including Korea which has high dependence on international trade with not very high technological capability of environment protection. Some of the developed countries have recently moved toward the creation of a new system of international regulatory measures on world trade in the name of Environment Protection. They Plan to impose strict control over the process and technology of production of good they are importing from other country. However, ever though the international regulatory measures, in a short term, could play a negative role on our trade capability, they could, in the long run, also play a role of helping hands if we usefully work out positive countermeasures as a result of hand-working government supported by industry and all the society as a whole.

Environment protection is one of the important political goals along with trade liberalization. Some of the institutions associated with it, however, either hinder trade or exert distorted influence and can arouse trade conflicts eventually. Therefore, harmony between environment protection and trade policy is becoming a crucial issue nowadays. Among the policies for environment, those related to climatic change are regarded as major tasks to deal with in the world commonly. Saying that it is for environment protection, advanced countries impose fines for environment protection on developing countries through border tax adjustments about the items imported from them. However, there is no such agreement about it internationally, so disputes often arise regarding what extent is appropriate as countries cope with it differently in their own way. Disputes about measures for climatic change are highly influential economically, and due to the severe conflicts of interests between states, they often tend to become politicized. Accordingly, we can say that such disputes affect international trade based on the WTO system seriously. When it comes to negotiation for climatic change, we should establish international systems urgently which can work fairly and effectively for all the countries joining in it. Therefore, it is important to examine the treatment of trade restriction measures intended to solve climatic change in international negotiations and establish definite conditions about which measures are allowed and which are not. In conclusion, we should devise rules for environment protection internationally which all the countries in the world can accept and agree on and also make the definite criteria of interpretation as well. Also, through those trade regulations, we should be able to accomplish environment protection globally and at the same time produce synergy, that is, economic growth through trading.

The Human Research Protection Program (HRPP) includes all subject protection activities and entities involved in the process of planning, reviewing, and conducting clinical research and it ultimately aims that research can be conducted ethically and scientifically while protecting the rights and welfare of research subjects. At the beginning of its introduction in Korea, it was settled down by adopting the United States HRPP, especially the form of AAHRPP element and regulations. However, regulations and operating forms of HRPP have been changed according to the Korean domestic research environment. Actually, all the Korean institutions are adopted the Korean HRPP guidelines that have been officially announced by the Ministry of Food and Drug Safety in Korea. Recently, Korean domestic laws such as the "Advanced Regenerative Biology Act" or "In Vitro Diagnostic Medical Device Act" have been dramatically innovated and our research environment becomes to be more complicated. Therefore, the development of a suitable Korean HRPP model considering the Korean research environment is strongly demanded. For the early settle down of the Korean HRPP model, the positive incentive method should be applied, when the HRPP is operated and/ or properly operated. These improvements in the Korean HRPP environment will eventually lead to the appropriate protection of subjects who are participating in human clinical research and the quality improvement of clinical research.

Background: A common genetic variant rs3757318, located in intron of C6orf97, was firstly identified to be associated with breast cancer (BC) risk by a genome-wide association (GWA) study. However, subsequent validation studies with different ethnicities have yielded conflicting results. Materials and Methods: We performed a meta-analysis to synthesize all available data for evaluating the precise effect of this variant on BC susceptibility. Results: A total of 8 articles containing 11 studies with 62,891 cases and 65,635 controls were included in this meta-analysis. When compared to the G allele, the rs3757318-A allele was significantly associated with BC risk with the pooled OR of 1.21 (95% CI=1.15 - 1.29, P<0.001) but with obvious between-study heterogeneity (P=0.040). Stratified analysis suggested that diversity of ethnicity along with control source may explain part of the heterogeneity. Similarly, significant associations were also identified in heterozygote, homozygote, dominant and recessive genetic models. Sensitivity and publication bias analyses indicated robust stability of our results. Conclusions: Our present meta-analysis demonstrated that the variant rs3757318 is associated with increased BC risk. Nevertheless, further studies are needed to clarify the underlying biological mechanisms.
