Despite the significant increase of Korean contractors in the international construction market, many SMCCs (Small & Medium Construction Companies) have suffered in the global financial crisis, and some of them have been kicked out of the international market after experiencing huge losses on projects. SMCCs face obstacles in the international market, such as an insufficient ability to gather information and inappropriate management of associated risks, which lead to difficulties in establishing effective business strategies. In other words, making immature decisions without an effective business strategy may cause not only the failure of one project but also the bankruptcy of the SMCC. To overcome this, the research presented herein aims to propose a decision support system for SMCCs, which would screen projects and make a go/no-go decision at the early stages of international projects. The proposed system comprises a double axis: (1) a profit prediction model, which evaluates 10 project properties using an objective methodology based on a historical project performance database and roughly suggests expected profit rate, and (2) a feasibility assessment model, which evaluates 17 project environment factors in a subjective and quantitative methodology based on experience and supervision. Finally, a web-based system is established to enhance the practical usability, which is expected to be a good reference for inexperienced SMCCs to make proper decisions and establish effective business strategies.

Purpose: The purpose of this study was to investigate perceived family support and quality of life in patients with cancer. Method: Data were collected from 83 cancer patients in the 3 cities of Korea. Family support was measured using the Tae's Family Support Scale and quality of life was measured using Functional Assessment of Cancer Therapy-General (FACT-G). Results: The mean scores of family support and quality of life were 30.48 and 53.04 respectively. Family support was significantly different according to marital status, education level, income, living together, helper, type of treatment, and weight change. Quality of life was significantly different according to the purpose of treatment, weight change, performance status, exercise, and sleep. There was a positive correlation between family support and quality of life (r=0.499, p<0.000). Conclusion: The study results underscore the importance of family support in improving the quality of life of patients with cancer.

We studied improvement in marine environmental impact assessment and related management systems of coastal sediments that are dredged inshore but disposed offshore. After reviewing and diagnosing the existing assessment procedures and problems, we recommend to design the core assessment items and improve the reliability of assessment byenhancing the quality assurance/quality control (QA/QC) and verification processes. We proposed eco-friendly disposal plan for dredging sediment such as reuse system in land development was explored. A marine environmental database system was established to support the assessment processes. Guidelines for marine research and modelling were proposed for improving assessment of dredging and disposal of coastal sediment. Also, applying of screening and scoping for marine environmental assessment was reviewed.

Environmental capacity assessment of Busan city was conducted to provide basis for planning on sustainable development and growth of the city. Using Onish model, assessment was carried out on amenities and service facilities for the citizens of Busan city. Ecological Footprint model was used to judge if the city exceeds the its environmental capacity and to estimate the extent of the excess if it exists. The analysis using Onish model revealed that the citizens of Busan city are generally well supported by the infrastructure and service facilities of the city. Water treatment and supply facilities have enough capabilities to support the city, whereas the relatively low rate of sanitary sewer supply (78%) suggests the need for further improvement in the wastewater area. The capacities of sanitary landfills are found sufficient enough to support the city for the next 10 years. The high value for the line length served per capita in the subway sector hints on certain inconvenience of commuters. All the air quality indicators meet the Korean and WHO standards except for $NO_2$. The ecological footprint model analysis produced EF indicators for Busan city of 3.04 ha/person and 2.54 ha/person for the years of 1993 and 2003, respectively. The decrease of the indicator from 1993 to 2003 is mainly due to the incorporation of Gijang area by Busan city in 1995, suggesting the importance of the ecologically productive area in the evaluation using this model. The analysis on the ecological deficit that is based on ecologically productive land shows that the consumption by Busan city exceeds its ecologically available production by 19,600% as of 2003. The area needed to support the consumption of Busan city in 2003 is 123 times as large as the present area of Busan city, which is substantially lower than the multiplier (742) obtained for Seoul city in 1997 but is higher than those observed for Chongju city (71 in 1999) and Ulsan city (39 in 2001).

The power plant is well known to influence air pollution as well as emission of green house gas. Because of increasing demand on electricity, the government set up the electric support action plan every 2 years. In this research, the impacts of power plants on the environment and region was studied. The study was focused on the establishment of power plant in Incheon area based on the 3rd electric support action plan. According to the 3rd electric support action plan, almost 80% of power plant in metropolitan area is planned to be built in Incheon area. The main influences of establishment of power plant are emissions of $SO_x$, $NO_x$ and PM and exceed the allocated local industry emissions, which means the emission allocation of other industry is difficult. In additions, the power plant exhaust $CO_2$ much more than other types of fuel such as waterpower generation, atomic power station. Although several supports are given in local government, these cannot cover the whole cost due to establishment of power plant. Subsequently, this study suggest the additional policy based on local consideration is needed and the current electricity distribution system should be reconsidered fundamentally in the lang term.

Purpose: This study was to identify the levels of functional status, depression, family support and their relationship among those variables in head and neck cancer patients. Method: The subjects were 100 patients with head and neck cancer patients who visited at outpatients clinic in one university hospital in Taegu. The instrument used for this study were Functional Status in Head & Neck Cancer - Self Report Scale developed by Baker(1995), Self-Rating Depression Scale by Zung(1965) and Family support assessment tool by Kang hyun-suk(1984). The data were analysed percentage, mean, t-test, ANOVA and pearson's corelation using SAS program. Result: There was significantly negative correlation between functional status and depression(r=-.71) and between depression and family support(r=-.56). The relationship of functional status and family support was significant as r= .33. Conclusion: It was found that functional status, depression and family support of head and neck cancer patient were closely related each other. Therefore it is necessary to design nursing intervention to enhance family support or decrease depression for improving quality of life in head and neck cancer patient.
