Background: Due to the asymmetry of information and knowledge and the power of bureaucrats and medical professionals, it is not easy for citizens to participate in health care policy making. This study analyzes the case of the insured organization participating in the Health Insurance Policy Committee (HIPC) and provides a basis for discussing methods and conditions for better public participation. Methods: Qualitative analysis was conducted using the in-depth interviews with the participants and document data such as materials for HIPC meetings. Semi-structured interviews were conducted with purposively sampled six participants from organizations representing the insured in HIPC. The meanings related to the factors affecting participation were found and categorized into major categories. Results: The main factors affecting participating in the decision making process were trust and cooperation among the participants, structure and procedure of governance, representation and expertise of participants, and contents of issues. Due to limited cooperation, participants lacked influence in important decisions. There was an imbalance in power due to unreasonable procedures and criteria for governance. As the materials for meetings were provided inappropriate manner, it was difficult for participants to understand the contents and comments on the meeting. Due to weak accountability structure, opinions from external stakeholders have not been well received. The participation was made depending on the expertise of individual members. The degree of influence was different depending on the contents of the issues. Conclusion: In order to meet the values of democracy and realize the participation that the insured can demonstrate influence, it is necessary to have a fair and reasonable procedure and a sufficient learning environment. More deliberative structure which reflects citizen's public perspective is required, rather than current negotiating structure of HIPC.

Purpose. This study of purpose was to compare and analyze the relationship among the isokinetic trunk muscular functions, flexibility and low back pain of elite weight lifter with regard of sex. Methods. we measured the level of low back pain, isokinetic muscular functions according to gender, then analyzed the relationship between isokinetic functions and the level of low back pain, between flexibility and the level of pain, between Athletic Career and the level. Results. In this study, the gender, the VAS point was $2.6{\pm}2.3$ and the VRS point was $2.3{\pm}1.3$ in males. The other side, in females the VAS points was $3.6{\pm}1.7$ and the VRS was $3.2{\pm}1.1$. There was significant negative correlation(r=-0.826) between the VAS point and the maximal flexion muscular strength per kilogram of $30^{\circ}/sec$ isokinetic exercise in female. also there was negative correlation between the muscular flexion strength per kilogram and the VRS point in female, but there was no significant relationship in male. Conclusions. In current study, these results suggested that the higher muscular flexion strength per kilogram is, the lower the level of low back pain is in female athletes. this is caused by the imbalance between Abdominal Muscles and Back Extensor in weight lifter. Therefore, there is the need to apply the program to improve the balance of trunk.

언제, 어디서나, 누구나 원하는 것을 배우고 즐길 수 있는 학습 도시의 구현은 개인의 자아실현을 도모하고 삶의 질을 높여 도시 전체의 경쟁력을 향상시키는데 중요한 역할을 한다. 학습 도시 구현을 위해서는 이를 실현할 수 있는 공간이 필요한데, 현실에서는 그 공간의 부족과 불균형화가 나타나고 있다. 본 연구에서는 평생학습시설의 공간 데이터 분석결과를 바탕으로 공간 서비스 취약지역에 초등학교의 유휴시설을 활용하여 공간적 불균형화를 해소하고자 하였다. 현재는 학교의 소극적인 참여로 그 효과가 미비하긴 하지만, 추후 학교의 적극적인 지원이 뒷받침해준다면 충분히 공간적 불균형을 해결할 수 있을 것이라는 결론을 도출하였다.

Computational flow dynamics(CFD) has been frequently applied to the waste incinerators to understand the flow performance for various design and operating parameters. Though it needs many simplifications and complicated flow models, the reasonability of its results is not fully evaluated. For example, the inlet condition is calculated from an arbitrarily assumed properties of combustion gas release from the waste bed, since the combustion in the bed is difficult to be predicted. In this study, the computational modeling and calculation procedures of CFD for the grate type waste incinerator were evaluated using comparative simulations. Though the assumption method on the generation of the combustion gas directly affected the temperature and gas species concentrations, the overall flow pattern was dominated by the secondary air jets. The gaseous reaction could be included by assuming the release of the products of incomplete combusion from the bed. However, the reaction effficiency cannot not be directly evaluated from the species concentration, since it is not possible to simulate the actual co-existence of fuel rich or oxygen rich puffs over the bed. In predicting the turbulence, the higher order model, such as Reynolds stress model, gave difference shape of local recirculation zones, but similar results was acquired from the standard $k-{\varepsilon}$ model. Introducing radiation model was required for accurate temperature prediction, but it also caused heat imbalance due to the fixed temperature of the inlet, i.e. the waste bed. Thus, the computational modeling procedures on incinerators and the analysis of the predicted results should be progressed carefully. Though not validated experimentally, current simulation method is capable of comparative evaluation on the flow-related parameters such as the furnace shape and secondary air injection using identical inlet conditions. Quantitative analysis using measures of the residence time and mixing is essential to compare the flow performance efficiently.

Background: Chronic obstructive pulmonary disease is characterized by emphysema, chronic bronchitis, and small airway remodeling. The alveolar destruction associated with emphysema cannot be repaired by current clinical practices. Stem cell therapy has been successfully used in animal models of cigarette smoke- and elastase-induced emphysema. However, the optimal dose of mesenchymal stem cells (MSCs) for the most effective therapy has not yet been determined. It is vital to determine the optimal dose of MSCs for clinical application in emphysema cases. Methods: In the present study, we evaluated the therapeutic effects of various doses of MSCs on elastase-induced emphysema in mice. When 3 different doses of MSCs were intravenously injected into mice treated with elastase, only $5{\times}10^4$ MSCs showed a significant effect on the emphysematous mouse lung. We also identified action mechanisms of MSCs based on apoptosis, lung regeneration, and protease/antiprotease imbalance. Results: The MSCs were not related with caspase-3/7 dependent apoptosis. But activity of matrix metalloproteinase 9 increased by emphysematous lung was decreased by intravenously injected MSCs. Vascular endothelial growth factor were also increased in lung from MSC injected mice, as compared to un-injected mice. Conclusion: This is the first study on the optimal dose of MSCs as a therapeutic candidate. This data may provide important basic data for determining dosage in clinical application of MSCs in emphysema patients.

전통적인 상호대차와 원문복사 서비스와 같은 도구를 통해 이용자의 정보요구를 충족시키는 것은 제한적이며 보다 심층적인 자원공유의 필요성이 제기되고 있다. 본 연구는 정보공유에 관련된 선행 연구를 분석을 통해 장애요인을 도출하고 정보공유와 관련된 이해관계자에 대한 분석을 제공하고 있다. 자원공유의 활성화와 관련하여 가장 중요한 이해관계자라고 여겨지는 사서의 인식을 보다 구체적으로 이해하기 위해 국내 대학에서 자원공유 관련서비스를 담당하는 실무사서 6명과의 면담을 수행하였다. 면담을 통해 규모가 큰 대학이 반드시 자원공유에 적극적이고 활발하게 서비스를 하고 있지는 않다는 것을 알 수 있었다. 무엇보다 자원공유에 대한 도서관간의 문화적 차이 그리고 담당 사서들의 태도에서 큰 간격이 있었다. 특히 연구에 대한 협소한 정의와 기관 규모의 불균형으로 인한 업무 폭주에 대한 부정적인 인식이 있었다. 전반적으로 자원공유를 새로운 차원에서 활성화시킬 수 있는 적극성이나 비전을 발견하기는 어려웠지만 자원공유 관련 서비스가 도서관에서 중요한 서비스로 인식되고 있고 담당자의 관심과 태도에 따라 발전의 가능성이 있다는 것을 알 수 있었다. 자원공유의 활성화, 보다 심층적이고 부가가치적인 자원공유 서비스를 창출하려면 먼저 사서들의 적극적인 개입이 요구되고 이를 위해 지역별, 주제별 사서 커뮤니티의 활성화가 필요하다.

The abundant nutrients contained in deep seawater are delivered by natural upwellings from the deep sea to the surface sea. However, the natural upwelling phenomenon is limited to specific areas of the sea; in other areas, the thermocline separates the surface sea from the lower layer. Thus, the surface layer is often deficient in nutritive salts, causing the deterioration of its primary productivity and ultimately leading to an imbalance in the marine ecosystem. Without a consistent supply of nitrogenous nutritive salts, they are absorbed by phytoplankton, resulting in a considerable problem in primary productivity. To solve this issue, a floating type of artificial upwelling system is suggested to artificially pump up, distribute, and diffuse deep seawater containing rich nutritive salts. The key technologies for developing such a floating artificial upwelling system are a floating offshore structure with a large diameter riser, self-supplying energy system, density current generating system, method for estimating the emission and absorption of CO2, and way to evaluate the primary production variation. Strengthening the primary production of the sea by supplying deep seawater to the sea surface will result in a sea environment with abundant fishery resources.

Panic disorder is a common psychiatric illness that causes considerable morbidity. However, the biological basis of panic disorder remains unclear. In this report, we present and summarize the current literature on functional neuroimaging studies related to the neurobiology of panic disorder. The findings were summarized and divided into six groups : (1) known brain structures related to anxiety, especially panic disorder ; (2) structural results ; (3) functional imaging studies at rest ; (4) functional imaging studies with challenge testing ; (5) neuroreceptor studies ; and (6) changes in the treatment of panic disorder. Based on the findings of these neuroimaging studies, it seems as though panic disorder involves the hippocampal and parahippocampal areas, including the amygdala, as well as some cortical regions, such as the temporal and prefrontal cortices. Panic disorder is known to be associated with an imbalance between the right and left hemispheres of the brain at rest or during panic attacks. During a panic attack, patients with panic disorder are likely to experience an increase in local activity in the cingulate, insula, midbrain, and so on. On the other hand, a widespread reduction in the cortical areas has also been reported in most provocation studies. Thus, panic disorder may be related to the excess activation of the fear networks in response to subtle environmental cues and insufficient inhibition from higher cortical control areas ; however ; further studies are recommended in order to fully understand the neurobiology of panic disorder.
