Recently, as the concern over environmental problem has been serious all over the world, carbon has become a key issue to mitigate the problem. In the field of Architecture, various sustainable assessment systems and LCCO2 assessment strategies have been developed, guiding low carbon building while planning. However, assessment system for low carbon neighborhood, which can be more efficient strategy, is still in the stage of research. In this paper, as a research for low carbon assessment system and planning guideline for neighborhood, scope meeting domestic condition has been set and sustainable assessment system for neighborhood, which is similar to low carbon concept, have been compared. LEED-Neighborhood Development, BREEAM-Communities, CASBEE-Urban Development, and GBCC-Apartment Houses were used for comparison. As a result, it is found that those systems has many differences in judging system, aggregating method, scope of evaluation, and relations with a building assessment system. The concern about carbon is not insufficient yet. Finally, assessment system for low carbon neighborhood, which is not only for establishing the plan, but also for giving guideline at the very first state of the plan, should be developed as fast as passible. With the result of this paper, establishment of assessment criteria and the way to measure quantitative $CO_2$ should be studied forward.

A comparative Life Cycle Assessment (LCA) among three types of Electric Motor Unit (EMU) Interior Panel (IP) was conducted. A functional unit for comparative LCA is a weight of IP for 1 EMU. It is assumed that Manufacturing stage and its upstream processes, Use stage and End of Life (EoL) stage are included in the boundary of product system. For Use stage, the weight of IP causes electricity consumption. It is assumed that aluminum IP is recycled and the other IPs are incinerated at the EoL stage. As a comparison results, aluminum IP has much larger environmental impact (5.162pt) than others (FRP IP; 4.069pt, Phenol IP; 4.053pt) even though recycling consideration is included. The manufacturing stage of aluminum IP has relative big environmental impact (1.824pt) and this point make the most important difference from other IPs (FRP IP; 0.1617pt, Phenol IP; 0.4534pt)). Despite of large weight difference between FRP IP (888.96kg) and phenol IP (316kg), the final environmental impact result has only little difference (0.016pt, 0.39%). With this result, the EMU designer can choose IP with a consideration of the environmental performance of IP.

The KGBCC(Korean Green Building Certification Criteria), which is the assessment standard of green buildings, is not enough to reflect all the current demands of residents. Therefore, the comparative analysis between the certification score and the residents' satisfaction of a promotional green apartment, a awarded green apartment, and a certified green building apartment was carried out to derive improvements of the KGBCC. The residents of selected three apartments were surveyed through the assessment items of the KGBCC. According to the research, the certified green building apartment shows the highest certification score and residents' satisfaction overall, compared with other two apartments. Finally, the improvements of KGBCC were determined through the reason of the residents' dissatisfaction. The KGBCC that is improved by this study can be used for the new assessment standard of green buildings.

There are two methods of quantifying the damages when the contract is avoided. One is 'concret' assessment, the other is 'abstract' assessment. The former looks to the actual cost incurred by the aggrieved party in concluding a contract for the substitute transaction, while the latter is based on the market price. The concrete method of assessment forms the starting point in the Civil Law systems. In the Common Law systems, it is likewise available. The aggrieved party is entitled to recover the difference between the cost of cover or (as the case may be) the proceeds of resale and the contract price. Both systems also recognize the abstract method of assessment. If the aggrieved party does not resell or cover, damages are equal to the difference between the price fixed by the contract and the market price. The CISG and the UNIDROIT Principles recognize expressly both concrete and abstract methods. Under the relevant articles, the aggrieved party can recover the damages assessed by one of the methods as well as any further damages such as loss of profit, incidental and consequential damages.

The purpose of this study was to develop a Korean assessment model for the patients with voice disorders. Interviews were conducted with 4 voice therapists and the results were analyzed by using a qualitative, constant-comparative design. According to the three themes emerged from the qualitative analysis, 10 subthemes were derived. The three main themes were 1) consideration on the disordered voice, 2) status quo of instrumental and perceptual evaluation, and 3) suggestions for the other voice therapists. The 10 subthemes can be summarized as the following: 1) judgment centering on the patients, 2) increase of the reliability of instrumental and perceptual evaluation, 3) voice therapists' positive participation in the assessment procedure of voice disorder.

For the purpose of the comparative environmental estimation of the incineration processes for domestic wastes, environmental impacts for several incineration processes for one ton of domestic wastes have been estimated by employing life cycle assessment as the environmental impact assessment method. The scheme of minimum production of environmental pollutants has been considered for three different incineration processes. The evaluation for latent influence on environment was carried out by using CML(Center of Environmental Science) method which was developed by University of Leyden in Netherlands based on the equivalency factor suggested by Korea Accreditation Board. The result of life cycle assessment has showed that the total cost analysis according to the amount of incinerating waste was dependent on the operating conditions of incineration process. In addition, the annual running cost for the incineration of one ton of wastes was estimated to be negatively dependent on the amount of wastes. The degree of environmental pollution was mainly due to the kinds of the wastes rather than by the amount of wastes.

Environmental impact assessment (EIA) is a tool used in planning development strategies and projects, and its use has been adopted into planning regulations in a number of countries. EIA has progressed from the consideration of pollution assessment, through the wider range of ecological assessment. Now EIA is required to consider the textbook of university students. Students taking lesson on EIA textbook are generally majoring in a variety of subjects, including environmental engineering, environmental health, environmental science, city planning, civil engineering, public policy, economics, and applied earth sciences. However, substantiality program of teaching material on EIA textbook has not been studied at expert society in the meantime, though a number of EIA textbook have been published every year in Korea. In current study, we presented the point at issue and improvement method of teaching material of EIA for student using domestic and foreign teaching materials and papers.

Probabilistic Ecological risk assessment (PERA) is extensive approach to qualify and quantify risk on the multi species based on species sensitivity distribution (SSD). As a while, deterministic ecological risk assessment (DERA) considers the comparison of predicted no-effect concentration (PNEC) and predicted exposure concentration (PEC). DERA is used to determine if there is potential risk or no risk, and it doesn't consider the nature variability and the species sensitivity. But PERA can be more realistic and reasonable approach to estimate likelihood or risk. In this study, we compared PERA used in developed countries, and proposed PERA applicable for the Korean water environment. Taxonomic groups were classified as "class" level including Actinopterygill, Branchiopoda, Chlorophyceae, Maxillapoda, Insects, Bivalvia, Gastropoda, Secernentea, Polychaeta, Monocotyldoneae, and Chanophyceae in this study. Statistical extrapolation method (SEM), statistical extrapolation method $_{acutechronicratio}$ ($SEM_{ACR}$) and assessment factor method (AFM) were used to calculate the ecological protective concentration based on qualitative and quantitative levels of taxonomic toxicity data. This study would be useful to establish the PERA for the protection of aquatic ecosystem in Korea.
