Although the patient's problem with access to health information has been improved due to rapidly developing information technologies, such as the internet, some patients still do not have enough ability to understand, interpret, and analyze the health information. Given this view on the patient's asymmetric information problem, if a doctor provides sufficient effort to help patients understand and interpret medical information, the efficiency of patient's medical care use could be improved. This paper shows firstly that the patient's inefficient use of medical care originates from his information problems, such as the misperception of the effectiveness of medical care and secondly suggests that if the doctor makes sufficient effort to correct patient's information problems, the inefficiency can be ameliorated. This paper also suggests the manipulation of a doctor's payment method can lead a doctor to provide optimal level of efforts which can in turn lead patients to use the optimal level of medical care. With an optimal level of effort, a doctor can more easily achieve a patient's compliance with the newly recommended amount of medical care.

In April 2009, in the wake of President Obama's Prague speech, the international community held four nuclear sec urity summits from 2010 to 2016 to promote nuclear security and prevent nuclear terrorism. The Nuclear Security S ummit has made significant progress in preventing terrorists from attempting to acquire nuclear weapons or fissile materials, but it still has limitations and problems. To solve this problem, the international community should resume the joint efforts for strengthening bilateral cooperation and multilateral nuclear security regime, and the participating countries should strive to protect their own nuclear materials and fulfill their commitments to secure nuclear facilitie s. Second, the United Nations(UN), the IAEA(International Atomic Energy Agency), International Criminal Police Or ganization(INTERPOL), the Global Initiative to Combat Nuclear Terrorism(GICNT), and the Global Partnership(G P) must continue their missions to promote nuclear security in accordance with the five action plans adopted at the Fourth Nuclear Security Summit. Third, the participating countries should begin discussions on the management and protection of military nuclear materials that could not be covered by the Nuclear Security Summit. Fourth, the intern ational community must strive to strengthen the implementation of the Convention on the Physical Protection of Nuc lear Material(CPPNM) Amendment and International Convention for the Suppression of Acts of Nuclear Terrori sm(ICSANT), prepare for cyber attacks against nuclear facilities, and prevent theft, illegal trading and sabotage invo lving nuclear materials.

This study was conducted to determine how well middle school students in the Ulsan area recognize trans fat and the amount of these compounds that they consume in their daily life. Students who recognized trans fat well could also identify trans fat contents on the nutrition label. However, recognition of trans fat was not associated with its intake. Students who thought it was necessary to learn about trans fat in school showed a tendency to consume less trans fat or to make more efforts to reduce its intake. Additionally, a preference for snacks had a significant influence on recognition and intake of trans fat. The overall, the following conclusions could be drawn from this study: 1) It is necessary for continuous efforts to teach students how to take snacks correctly and help them form good dietary habits both at home and school. 2) Both development of basic educational materials and the systematic education about trans fat at home and school are urgently needed to instill good dietary habits regarding trans fat. 3) It is highly recommended that the school meal service should take students' preferences into consideration and provide them with good nutrition and a balanced diet, and efforts should be made to contribute to the formation of good dietary habits.

Meta-thinking is a kind of thinking beyond certain scope or border, which sees objects as an expanded definition exceeding its essence. It can be experienced when people come into contact with new things. As for digital media, experience acquired from computer screen makes users' thinking be changed continuously and help their thinking to be expanded. Today, studies on development of digital technology regarding virtual reality (VR) and experience obtained from digital media become a topic of conversation, however, this experience depends on the sense of sight through screen. Actually, transparent experiences in digital media are not the same with those in real world, therefore, this study investigated experience expansion through interaction with real things which are much closer to daily lives than virtual experiences. It can be found in media art which induces positive participation of audiences and shows them a new meaning through delight and amusement experienced in the process of interaction. Visual expression in digital media should be more than spectacular which is only full of excessive images. In addition, interface should not be remained as an expression from technological attempts, instead, it is necessary to find humans aspiration with meta-thinking which accepts things expansively and visualize their experiences.

This paper aims at investigating the developments and challenges of Northwest Pacific Action Plan (NOWPAP), a regional cooperation mechanism to protect marine environment in Northeast Asia. As one of 16 UNEP's Regional Seas Program, NOWPAP has evolved since its inception in 1994. Based on the belief that a cooperative institution may work more efficiently to address common regional concerns on marine environment, China, Japan, Russia and South Korea have developed NOWPAP under the UNEP's leadership. NOWPAP now has its own independent secretariat, and 4 regional activity centers while expanding its partnership with other institutions. However, NOWPAP must address several challenges that it now faces for better achievement of its goals. They include consideration of unique geopolitical situation in this region, participation of North Korea, incorporation of sustainable development concept in its activities, reconsideration of equal opportunity principle for more efficient cooperation, and securing sufficient financial resources.

The deposition of sewer solids during dry weather in combined sewer systems results in a loss of flow capacity that may restrict flow and cause a local flooding and enhanced solids deposition. Sewer solid accumulations in drainage systems also create the 'first-flush' phenomena during wet weather runoff periods. In order to solve these problems, measurement of these loadings for a given sewer system for extended period is needed but this task is very difficult and extremely expensive. In this study, generalized procedures for estimating sewer sediment solid during dry weather in combined sewer systems developed by the U. S. Environmental Protection Agency were applied in a drainage system in Korea. As result, the appropriate equation can be selected and applied according to the available data. However, the estimated solid sediment shows considerable difference between methods which classified by model and estimation methods of variable. The estimated values using equations (1) $\sim$ (4) are greater than that of equations (5) $\sim$ (9) and intermediate models show greater values than elaborate or simplest models. The comparison between simulated and measured solid deposition is difficult due to the absent of measurement data, but this estimation method can be used usefully for the management of sewer solid with reduction of cost and effort if the measurement is carried out and the equation is adjusted according to the actual drainage systems in Korea.

The purpose of this study was to identify contents of Taekwon and to improve specialized knowledges and practical abilities for Taekwondo majoring university students. The sample was categorized into college and student. The first round survey was divided into two parts in finding possible ways to improve practical abilities from students and school authority perspectives. The second round was conducted through survey by dividing respondents into students and school authority. The third round was performed to identify the nessessities and problems in relation to specialized knowledge and practical abilities such as sparring, poomsae, and demonstration. Based on the findings, three critical themes were identified: motivating them to accumulate specialized knowledge, providing opportunities to practice, and offering diverse job directions. Students indicated several critical themes such as recognition of job opportunities in different domains, endeavour to increase communication ability with others in different domains, reconsideration to learn things in different domains, and efforts to take an interests in life-time Taekwondo. The findings provide ideas in applying practical knowledge into the field and in changing students' perception in terms of Taekwondo majoring. They are specialized knowledge and practical ability improvement based upon college authority and students (15 college authority items, 9 student items).

Successful implementations of domestic public construction projects have been increasingly concerned with the efforts to improve the inefficient execution. However, the existing factors causing the inefficient execution have been repeatedly occurred in many projects. This is because the previous studies have been concentrated on identifying the factors without in-depth analysis and systematic prioritization. This study has clarified the characteristics of the inefficient public construction projects, identified the causes, constructed their hierarchical structure, and analyzed the impacts on them. In particular, the critical factors causing the inefficient execution are prioritized by the outcomes derived from the questionnaire surveys, which is limited to the pre-construction stage. They are utilized in prioritizing the institutional and political improvements. However, in the future, the analytic and detailed guideline for remedying the factors causing the inefficient execution of a project should be studied, and their analysis will be extended to the construction stage.
