Objective Chronic pain frequently coexists with psychiatric symptoms in patients diagnosed with complex regional pain syndrome(CRPS). Previous studies have shown a relationship between CRPS and the risk of suicide. The purpose of this study was to assess riskfactors for suicidal ideation in patients with CRPS. Methods Based on criteria established by the International Association for the Study of Pain, 39 patients diagnosed with CRPS Type 1or Type 2 were enrolled in this study. Suicidal ideation was assessed using item 3 of the Hamilton Depression Rating Scale (HAMD), andsymptoms of pain were evaluated using the short form of the McGill Pain Questionnaire (SF-MPQ). Psychiatric symptoms were assessedin using the Structured Clinical Interview for DSM-IV Disorders (SCID-I, SCID-II), the HAMD, the Hamilton Anxiety RatingScale (HAMA), the Global Assessment of Functioning Scale (GAF), and the Pittsburgh Sleep Quality Index (PSQI). Results Twenty-nine patients (74.4%) were at high risk and 10 (25.6%) were at low risk for suicidal ideation. Risk factors significantlyassociated with suicidal ideation included depression (p=0.002), severity of pain (p=0.024), and low scores on the GAF (p=0.027). Nosignificant correlations were found between suicidal ideation and anxiety or quality of sleep. Conclusion Significant risk factors for suicidal ideation in patients with CRPS include severity of pain, depressive symptoms, and decreasedfunctioning. These results suggest that psychiatric evaluation and intervention should be included in the treatment of CRPS.

The purpose of this paper is to search the strategies of preventing local extinction and facilitating local regeneration in Korea. Firstly, this paper reviews the theoretical backgrounds about the cause of local extinction, and finds the successive ways of local revitalization. Secondly, this article studies the effect of local thematic map production to activate local regeneration. Thirdly, this paper insists on the necessity of ecological map production for eco-city planning as a strategy of local regeneration. For ecological mapping, local government should make ecological zoning map, urban ecology status diagrams to search the locus of ecological assets, and produce land use map to defend over-development in the region. Local citizen also must learn the efficacy of the sense of place, and participate in the local thematic mapping by using of digital technologies such as EcoMap, mappler and naturing app.

This study analyzed the sensitivity of mechanical facilities in multi-unit dwelling according to the energy supply and heating type for 500 households of LH apartments. Accordingly, an optimal setting plan for each ZEB grade was presented, and the effects of energy cost and carbon emission reduction were analyzed. In the standard type model, it was found that the difficulty of achieving ZEB was higher in the public tract house than in the rental house. In order to achieve high-level ZEB, it is necessary to optimize mechanical facilities and improve performance. According to the annual apartment supply plan, apartment supplied in 2050 are expected to reduce energy cost by 79.7% and carbon emissions by 94.6% compared to apartments supplied in 2021. 본 연구는 탄소중립이 화두가 되고 있는 시점에서 공동주택의 ZEB화에 따라 탄소저감 효과와 에너지비용 절감 효과 도출을 하고자 하였다. 건축물에너지효율등급 및 제로에너지건축물 인증 평가 프로그램인 ECO2를 활용하여 LH에서 공급하는 500세대 규모의 임대주택과 분양주택을 표준모델로 설정하여 개별난방과 지역난방 모델에 적용가능한 기계설비 요소의 민감도를 분석하였다. 이를 바탕으로 도출된 우선순위를 고려하여 ZEB 등급별 기계설비 로드맵을 제시하고, 연도별 LH 공동주택 ZEB 로드맵 이행에 따른 탄소배출량 저감 및 에너지비용 절감 효과를 분석하였다. 그 결과는 다음과 같다. (1) LH 공동주택 표준형태로 임대주택은 26 ㎡+37 ㎡+46 ㎡ 조합으로 구성하였고, 분양주택은 임대주택 대비 비교적 큰 평면형태인 46 ㎡+55 ㎡+84 ㎡ 조합으로 구성하였다. 공동주택에 적용하는 기계설비 요소의 민감도 분석을 위해 18가지의 기계설비 조합 모델을 수립하였다. (2) 민감도 분석 결과, 개별난방 단지는 보일러 효율, 지역난방 단지는 지역난방 배관구간길이가 1순위로 도출되었으며, 개별난방+지열 적용 단지 및 지역난방+지열 적용 단지는 지열히트펌프 COP, 지역난방+태양열 급탕시스템 적용 단지는 지역난방 배관구간길이 및 태양열 집열기 유형의 변경(평판형→진공관형), 지역난방+연료전지 적용 단지는 연료전지의 발전효율이 1순위로 도출되었다. (3) LH 공동주택 ZEB 등급별 모델을 설정하여 탄소배출량 저감 및 에너지비용 절감 효과를 분석한 결과, 2021년에 공급되는 공동주택 대비 ZEB 1등급이 100% 보급되는 시점인 2040년에는 탄소배출량 94.6% 저감, 에너지비용 79.7%만큼 절감이 가능할 것으로 분석되었다. 2050년 탄소중립을 위해서는 전체 건축물 중 에너지사용량을 가장 많이 차지하고 있는 공동주택의 에너지절감 노력이 절실하다. 이에 따라, 공동주택의 제로에너지건축물 고등급화는 필수불가결한 상황이다. 공동주택의 에너지절감을 위해 적용할 수 있는 패시브 기술요소인 단열성능, 기밀성능은 한계치에 다다랐으며, 에너지생산을 위해 가장 많이 활용되고 있는 태양광 발전시스템의 경우, 설치공간의 제약사항으로 인해 에너지생산량의 확보는 한계가 있다. 따라서, 공동주택의 고등급 제로에너지건축물 구현을 위해서는 기계설비의 기술개발 및 최적의 설비시스템 조합, 다양한 신재생에너지의 적절한 활용이 필요할 것으로 판단된다.

This study analyzed the effects of improving energy performance, thermal comfort, reducing energy costs and carbon emissions through green remodeling for neighborhood facilities and houses that were completed more than 35 years ago. As a result of analyzing the effects of improving the indoor surface temperature of the bedroom on the second floor of the house, in corner of building envelope was improved the most to 16.51℃. The surface temperature in the center of the glass was also improved by 11.77°C, which is expected to significantly improve the discomfort of the occupant due to the influence of cold draft near the window in winter. In addition, it was analyzed that the amount of heat loss had a 44% reduction effect. As a result of the overall analysis of energy performance before and after green remodeling, the energy demand of houses was reduced by 55.7% from 268.8 kWh/㎡·yr to 119.2 kWh/㎡·yr, and the primary energy consumption was 233.7 kWh/㎡·yr at 578.6 kWh/㎡·yr. It was reduced by 59.6% in ㎡·yr. Neighborhood facilities reduced their energy demand by 21.3% from 220.0 kWh/㎡·yr to 173.2 kWh/㎡·yr, and reduced primary energy consumption by 89.0% from 391.8 kWh/㎡·yr to 43.2 kWh/㎡·yr. It was confirmed that the rate was 85.23%, which was at the level of a zero-energy building 2nd grade. The recovery period compared to energy cost and cost investment was analyzed to reduce the annual energy cost by 2,159,963 won/year due to green remodeling, and the recovery period compared to cost investment will take a total of 11.1 years based on the material cost.

This study indicates an error of positive epistemology that is not competent enough for the cause analysis and cure of failure of government owing to its immoderate persistence in causal explanation.Therefore, this article searches a new epistemology that is fit for the introspection of fallacy of government. A new epistemology based on phenomenology and critical theory provides a helpful method that can effectively understand the genuine because-motive of administrators who cannot do their best because of the pressure of bureaucratic organizational structure. The new epistemology called Verstehen method finds a solution to the failure of government.Its solution is a rediscovery of human value through the phenomenological essential intuition, and an emancipation of administrators in coercive bureaucratic organizations by the critical self-reflection and ideology Critique.

Now, the local self-government is enforced in Korea. For that reason, there are much discussions about desirable directions of administrative capacities of our local administrators. Our local public servants` responsiveness to citizen`s demands and their productivity og public goods and services, have been and are at very low level owing to the long-term centralization of administrative power. The low administrative capabilities of our local administrators interrupt the institutionalization of our local self-government. It`s a matter of grave anxiety. Local public service personnels are a very important point to the success of local self-government and the establishment of good cities. Korean local administrators must respond citizen`s demands and manage the human/financial resources effectively. In this interrelationship, the entrepreneurial government that is a recent orientation of the local government in U.K., U.S.A. and Japan, give us the fresh implications of local administrative reform. Good enterprises do eagerly market survey and after services for their customers in order to survive fierce market competitions. They also have the basic productive cost mind, and make an effort for high profit. Likewise, entrepreneurial local governments in foreign countries are developing their administrative abilities for the sake of client-oriented, efficient, productive and profitable public administration. It`s a market approach to public management toward ‘more services and less taxes’. The development of client-oriented, efficiency-oriented, productivity-oriented, and profit-oriented administrative capacities is a very urgent task of our local administrators. Because their abilities are key point to the success of local self-government and the building of good cities in Korea.
