The Ministry of Environment plans to improve quality of water which is achieved over 85% in rivers and 94% in lakes of the whole country as "Good Water" until 2015. Also, the law of evaluation of water quality and water quality goal were made newly. So, the water quality has evaluated by using new law since 2007. This study evaluated whether "Good Water" and" Water Quality Goal" were achieved or not in 22 middle-sized districts and major 10 lakes of Geum river. The achievement rates of rivers decreased and the achievement rates of lakes mostly were the same for 5 years. In 2007, the achievement rates of "Good Water" were 50% in rivers and 50% in lakes. The achievement rate of "Water Quality Goal" were 59.1% in rivers and 20% in lakes. The water quality in 2007 was evaluated worse than last year in case of rivers. The evaluations of Korea-Comprehensive Water Quality Index(K-CWQI) showed that achievement rates of "Water Quality Goal" were 81.8% in rivers and 0% in lakes. The statistical correlation analysis showed that correlations between BOD and COD were meaningful at the downstream, compared to upstream, generally. In case of lakes, correlations between COD and temperature were meaningful. Also, correlations between COD and Chl-a were meaningful. The Trophic State Index ($TSI_{KO}$) showed that the half of lakes are major over eutrophic status in lakes. These analytical methods such as K-CWQI, $TSI_{KO}$, statistical correlation analysis could be additionally helpful for evaluation of water quality and provide basis data for understanding characteristics of watershed in Geum river.

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.

최근 해양환경법제도에 관한 정비작업이 활발하게 진행되고 있는바, 이는 "지속가능한 개발원칙"과 "사전예방주의 윈칙"을 "법(law)"의 형태로 내재화하고 "정책(policy)"으로 실현하기 위한 노력의 일환이라고 할 수 있다. 연안침식 방지, 기후변화 대책마련과 같이 해양환경에 관한 입법수요는 지속될 것으로 예상된다. 향후에는 해양환경 관련 법률의 법체계를 합리적으로 정비함으로써 법률간 연계성 및 정책의 효율성을 제고하는 것이 필요하다. 또한 해양환경을 효율적으로 보전하기 위해서는 법률과 정책의 정비와 함께 체계적인 연구와 조사가 지속적으로 이루어져야 한다.

This study has a purpose to provide information to help develop nursing intervention for demented elderly staying at home. For this purpose I analysed the relationship of patients' disturbing behaviors with their demographic and social characteristics, premorbid personality, and present environmental characteristics through questionnaire survey on their family members. The survey was performed through direct interview, telephone contact. and mail in the regions of Pusan and Gyeongnam. Among family members contacted. 112 ones made an appropriate response to the survey. The statistical package SAS was utilized for descriptive statistics, correlation coefficients, stepwise multiple regression, and cluster analysis. The results of the study were as follows: 1) Demographic and social characteristics of the patients surveyed are female 81.3%, average age 81.4 years, lack of schooling 83.0%, spouse dead 73.2%, having no other disease 58.9%, average duration of dementia 3.8 years, no medical treatment for dementia 84.8%, good married life 40.2%, and primary care given by daughter-in-law 49.1%. 2) Aggressive Psychomotor Behavior(APB) was observed in a way statistically meaningful in case that primary care was given by daughter-in-law, while Nonaggressive Psychomotor Behavior(NPB) was in case of good married life and primary care given by other than daughter-in-law and spouse. Verbally aggressive behavior (VAB) was observed in groups of female, spouse dead, bad married life, and daughter-in-law's primary care. As for Passive Behavior(PB), it was observed in case that patients had educational background of not less high than middle school and that they were having medical treatment. Functionally Impaired Behavior(FIB) was observed in age group of 60-69 and more than 90, in patients' group having no other disease, and in case that the duration of dementia was not less than 5 years. 3) Premobid Neuroticism(N) showed positive correlation with APB and VAB, while Openness (O) did negative correlation with PB. Agreeableness (A) was proved to have positive correlation with PA and FIB, but to have negative correlation with APB and VAB. In addition, Conscientiousness(C) showed negative correlation with APB and VAB. 4) The worse the psychosocial environment was, the more NPB and VAB were observed. 5) APB was explained 24% by C and primary care-giver, while NPB was explained 28% by psychosocial environment, having other disease or not, and married life. VAB was explained 40% by A. sex, and married life. On the other hand PB was explained 33% by O, A. N, and having medical treatment or not. But any significant factor was not found to explain FIB. 6) A cluster analysis was performed on disturbing behaviors of demented elderly staying at home. It enabled to regroup the demented elderly in 5 patterns: high scored in NPB, high scored in FIB. high scored in NPB and VAB, moderately scored in most disturbing behaviors, and low scored in all areas. In conclusion, disturbing behaviors of demented elderly not only reflect their premorbid personality in the past, but also are affected by their present psychosocial environment. Therefore, it is necessary to encourage and respond them with understanding their disturbing behaviors in relation to their past premorbid personality. In addition, it is important to provide them better psychosocial environment in order to reduce their disturbing behaviors.

Batch slurry experiments were conducted to develop cement/slag/Fe(II) system that could treat hazardous liquid wastes containing halogenated organic solvents. Portland cement in combination with Fe(II) was reported to reductively dechlorinate chlorinated organics in a modified solidification/stabilization process. TCE (trichloroethylene) was used a model halogenated organic solvent. The objectives of this study were to assess the feasibility of using cement and steel converter slag amended with Fe(II) as a low cost abiotic reductive dechlorination and to investigate the kinetics of TCE dechlorination over a wide range of TCE concentration. From the result of screening experiments, cement/slag/Fe(II) system was identified as a potentially effective system to treat halogenated organic solvent. Kinetic studies were carried out to further investigate degradation reaction of TCE NAPL (Non Aqueous Phase Liquids) in cement/slag/Fe(II) systems by using batch slurry reactors. Degradation rate of TCE solution in this system can be explained by pseudo-first-order rate law because the prediction with the rate law is in good agreement with the observed data.

Most models for the simulation of multi-phase flow and multi-species transport employ the capillary approach which uses the Darcy's law for the representation of mass flux of each phase. The capillary approach based on the Darcy's law require many empirical coefficients with complex functional dependencies rather than rigrous mathematical and physical formulation. The shortcoming of the capillary approach cause the numerical errors in the simulations by the multi-phase flow and transport models. This study discuss some of the problems related with the use of models.

We have simulated the effect of fracture characteristics on reduction of effective permeability of the fractured rocks due to in-situ bacteria growth. A nutrient is injected continuously for growth of in-situ bacteria. We used a power law for fracture length distribution and a fBm for fracture aperture spatial distribution. The results show that in-situ bacteria growth reduces the Permeability hyperbolically, but the porosity of backbone fracture does not change significantly. It shows that reduction of the permeability proceeds at faster speed for smaller value of length exponent(a) and for larger value of Hurst exponent(H). The fracture length distribution has stronger effect on speed of reduction than the aperture spatial distribution. The time needed to reduce permeability is inversely proportional to the hydraulic gradient.

This research studies the Virtual Reality simulation of Newton's physics law on rigid body type of objects for physics learning. With network support, collaborative interaction is enabled so that people from different places can interact with the same set of objects in Collaborative Virtual Environment. The taxonomy of the interaction in different levels of collaboration is described as: distinct objects and same object, in which there are same object - sequentially, same object - concurrently - same attribute, and same object - concurrently - distinct attributes. The case studies are the interaction of users in two cases: destroying and creating a set of arranged rigid bodies. We identify a specific type of application for contents authoring with modeling systems integrated with real-time physics and implemented in VR system. In our application called Virtual Dollhouse, users can observe physics law while constructing a dollhouse using existing building blocks, under gravity effects.
