This study was carried out to investigate the effects of breakfast service on nutritional status, hematological status, and attentiveness of children in low-income families. The subjects were 19 boys and 13 girls between 7 and 11 years old. The subjects were divided into a control group and a breakfast service (BS) group, in which 12 boys and 5 girls received breakfast from February 1 to December 31, 2010. The results can be summarized as follows: intakes of energy, protein, carbohydrate, calcium, iron, zinc, vitamin A, vitamin $B_2$, niacin, and vitamin C in the BS group were significantly higher than those in the control group. In the BS group, the intakes of calcium, folic acid, and vitamin C were lower than 75% of recommended intake levels. There were no significant differences in the total blood protein level and total cholesterol level between the BS group and control group. A blood albumin level was significantly higher in the BS group than in the control group. Systolic blood pressure was higher in the BS group than in the control group, whereas the diastolic blood pressure showed no significant difference between the groups. A dietary attitude score increased according to breakfast service and nutritional education. No significant differences were found in the capacity value and continuity value between the two groups, but the control value was significantly higher in the BS group than in the control group. Therefore, to sustain the effect of breakfast service and improve nutritional status for children skipping breakfast in low-income families, nutrition intervention services, as well as legal and financial support by the government should be provided.

우리나라와 일본정부는 해운정책의 일환으로써 계획조선정책을 실시하였다. 한국의 경우, 선복의 확보, 자국화자국선의 실시, 국내조선산업과 해운을 연계하여 육성하기 위하여 계획조선제도의 도입을 실시하였다. 일본도 마찬가지로 제2차세계대전중에 파괴된 상선대의 회복 및 자국조선산업의 활성화를 위하여 계획조선제도를 실시하였다. 우리나라의 계획조선정책은 선박자본측면에서 해운회사의 부담을 경감시킴으로써 우리나라 해운회사들이 저렴한 선원비와 화물유보정책 등의 지원하에서 급속한 성장을 이룩하는데 일조를 담당하였음은 인정되나 문제점도 발견된다. 첫째, 조달재원의 금리적인 측면에서 선진 해운국의 조달금리와 비교하여 볼 때 열위에 있었다는 점이다. 둘째, 계획조선을 위한 조달재원이 부족하여 수요를 충족시키지 못한 점이다. 셋째, 한국정부는 시장환경변화에 따른 신속한 정책의 반영이 결여되어 있었다. 오늘날 세계해운시장이 개방화, 국제화되고 있는 시점에서 경쟁력 있는 선박의 확보는 해운기업의 중요한 경영요소의 하나이며 우리나라도 이를 지원할 수 있는 방향으로 해운정책이 수립되어야 한다.

Many Asian countries are suffered from various problems on water, which include the need for increased access to improves water supplies and sanitation through investments in infrastructure and capacity building, the balances water management system between development and ecosystem, and the need to reduce the human populations'vulnerability to water-related disasters, in particular, from climate variability and evolution. Decison makers are the most influential people in policy making and solving global water problems is central issue in eradicating poverty and achieving sustainable development (MDG). They across the world form an integral part of the architecture of national or regional governance. Their role covers a range of decision-making processes including passing legislation, scrutinizing government policy, and representing citizen through the election. We must ensure that these quiet but important issues get the political space, financial priority and public attention they deserve. Regional bodies such as the EU have also enacted legislation which introduces rules on water quality and other enforceable mattera across state boundaries. With this growing body of laws and policies on water issues, the role of decision makers is growing. Recognizing this role, decison makers' platform is essential to provide an opportunity to discuss crucial water issues in each country or region and for the purpose "2010 Parliaments for Water in Asia" has planned and organized to investigate our common issues and goals. During the meeting, we have an opportunity to observe water policy of Bangladesh, Bhutan, China, Mongolia, New Zealand and the Philippines and share the views on what needs to be done to move forward by decision makers for the future of water. In conclusion, the process of developing the decision makers' platform in each region would be ultimately essential point to increase the awareness of the developed and developing countries' roles, knowledge to clarify roles and responsibilities of each stake holders and finally be a major actor for resolving not only water challenges also issues of human settlements.

Purpose: This paper studied about the integration for management system of representative international standard related to sustainable development. The well-known International standards such as ISO 9001, ISO 14001 and OHSAS 18001 (ISO 45001) can be operated in accordance with the organizational situation individually, or in a variety of ways of integration. It can be applied to help organizations utilizing the newly established "ISO IEC Directive Part1 Annex SL", when integrating quality, environmental and safety & health management systems based on international standards. Methods: We conducted an empirical survey of management executives and experts to study how three factors (management systems, organizational capabilities and integration methods) could affect business performance. Results: The questionnaire was analyzed using AMOS structural equation model. Quality, environmental and safety and health management systems affected management performance, and integration methods of management system affected business efficiency, risk performance and financial performance. Integration method is also important because organizational competence affects various aspects of integrated management. However, factors that affect integration should also be considered in terms of organizational capabilities. This is because organizational capacity influences the integration plan. Conclusion: To integrate the document system at the strategic level, management should actively participate in integrated operations to integrate organizations, eliminate duplicate tasks, and foster document integration experts to reflect the characteristics of individual standard. In the case of document integration, quality management is focusing, but once ISO 45001 is issued, the use of Annex SL is increasing, and Quality, environment and safety & health integration will also be expanded. It is possible to increase the effect of integration by strategically approaching and establishing organization document system rather than simple integration according to management system standard arrangement.

The revised Urban Park regulations newly adopt Theme Parks in order to enhance richness and diversities of urban services to communities. However, the regulations ambiguously define the main facilities and service programs of the theme parks. And there have been increasing concerns about confusions in terms of the main facilities and service programs of the theme parks among landscape designers/planners, local governments and relevant field of areas. Misunderstanding on the facilities and service programs of the theme parks may lead to ruin the purposes of the new urban park regulations. In the lights of these, this paper tries to reach a consensus for main facilities and service programs of two theme parks including athletic park and waterfront park, based on measured potential users' preferences with a conjoint choice model. For waterfront parks, potential users show low preferences or negative responses to facilities which are perceived as un-environment friendly. They also show high preferences on ecological areas sitting near to streams. For athletic parks, potential users show demand to introduce something different facilities and atmosphere from existing athletic parks. The demands are particularly high for children's play ground facilities and service facilities. This study also show some methodological examples to compute the carrying capacity with two hypothetical alternatives. This approach might be beneficial for local governments which are wish to alternate the park size on the basis of local conditions such as their financial conditions and land availability.

A study on estimation of the Levelized Cost of Energy (LCOE) was conducted for the Korean onshore wind farms. The LCOE was estimated on the basis of the actual wind farm data from Data Analysis, Retrieval Transfer system (DART) run by Financial Supervisory Service. Recently, social discount rate of Korea dropped from 5.5% to 4.5%, which was taken into account for this study. The onshore wind farms studied accounted for 42% of all the onshore wind farms of South Korea. Capital Expenditure (CapEx) and Operation Expenditure (OpEx) were calculated from the actual data, while Capacity Factors (CFs) were obtained from the wind farms of five provinces. Their distributions were estimated using Maximum Likelihood Estimation method, and then Monte Carlo Simulation (MCS) was performed for estimating LCOE, Levelized Fixed Cost (LFC), and Levelized Variable Cost (LVC). As a result, the LCOEs at the two discount rates, 4.5 and 5.5%, were 142 and 152 $/MWh, respectively, which were lower than that of financially viable onshore wind project of Korea. The 1% drop of social discount rate was estimated to result in a 10 $/MWh decrease in LCOE and a 4 $/MWh in LFC, which can be an advantage for wind project investors.
