본 연구에서는 대구광역시 중구의 국채보상운동기념공원과 2.28기념중앙공원을 대상으로 도시공원의 조성 후 열섬 영향 정도와 미기후환경 변화를 정량적으로 분석하여 과거대비 미기후 측면의 효율성 검증과 도시내 공원의 중요성 및 필요성에 대해 살펴보고 이를 바탕으로 미기후개선을 위한 친환경적 도시공원 계획 및 도시계획 방안 제시를 목적으로 한다. 본 연구에서는 대구광역시 중구에 위치하는 2.28기념중앙공원과 국채보상운동기념공원을 대상으로 3차원 미기후분석프로그램인 ENVI-met을 이용하여 미기후환경(온도, 습도, 바람)의 변화를 분석ㆍ고찰하였다. 2.28공원 및 국채보상기념공원 조성으로 인한 미기후환경 변화를 요약하면, 지점별로 차이가 있지만 기존대비 각각 2.27%, 1.50%의 온도저감효과가 있는 것으로 나타났다. 습도는 기존대비 각각 5.52%, 2.83%의 상승효과가 나타났다. 본 연구는 과거의 미기후환경을 예측하여 공원 조성을 통한 미기후환경의 변화를 정량적으로 분석하였다는데 가장 큰 의의가 있다. 향후 도시계획 이전에 미기후의 변화를 모의하여 계획에 반영한다면 보다 쾌적한 도시조성에 효과를 줄 것이라 판단된다. This study examined the effect of Gukchae-bosang Memorial Park(GBM park) and 2.28 Jung-ang Memorial Park(JAM park) located at Jung-gu, Daegu on heat island phenomenon. The changes in micro-climate environment after the development of urban parks were analyzed quantitatively to evaluate the efficiency of the parks in terms of micro-climate control. The importance and necessity of urban parks are reviewed based on the analysis, and the guidelines for eco-friendly park and town planning are suggested. In this study, the microclimate environment factors of the urban parks, such as temperature, humidity, and wind, were analyzed and examined by ENVI-met -- a three dimensional micro-climate analysis program. The micro-climate environmental changes caused by the urban parks are as follows. The temperature decreasing effects by the parks were 2.27%(JAM park) and 1.50%(GBM park), and the humidity increasing effects were 5.52%(JAM park) and 2.83%(GBM park) respectively. The significance of this study is that the changes of micro-climate environment by urban parks were analyzed quantitatively on the assumption of the past micro-climate environment. It is expected that the simulation of micro-climate changes from the results of this study helps planners develop a better plan to create more pleasant urban environment.

기후변화 적응을 위한 대형 재해 위험의 분산체계와 보험제도 -해외 사례와 제도를 중심으로-

임채욱 ( Che Oug Rim ) 한국법정책학회 2016 법과 정책연구 Vol.16 No.1

1997년 기후변화 적응을 위한 교토의정서 체결 이후 2015년 파리기후협약이 체결되면서 기후변화에 대한 심각성과 그 적응책 마련이 시급한 시기임을 알리는 계기가 되었다. 기후변화 적응책은 크게 기후변화를 늦추는 방법과 기후변화로 인한 피해 복구로 나눌 수 있다. 기후변화를 늦추는 방법은 온실가스 감축으로 대표되며, 현재 대부분의 국가의 기후변화 적응 정책은 주로 온실가스의 배출을 줄이고 통제하는 것을 목적으로 하고 있다. 그러나 온실가스의 감축 만큼 기후변화 피해의 방지와 리스크의 분산을 통한 복구 비용의 마련도 중요한 문제이다. 현재까지 후자에 대한 제도적 정책이나 법규범은 구축되지 않고 있다. 이와 관련하여 국제연합, 세계은행, 유럽연합, 미국정부 및 재보험사를 중심으로 보험의 위험 분산체계를 활용하여 기후변화 위험을 대비하고 있는 것을 확인하였다. 이에 본 논문은 궁극적으로 우리나라의 기후변화 위험을 분산하기 위한 대책으로 보험의 활용을 제안하기에 앞서, 기후변화 적응을 위한 해외의 보험제도와 기존의 보험제도를 비교하여 그 차이점을 중점적으로 고찰하고자 한다. 먼저 기후변화 적응을 위한 재정 안정 정책으로 보험제도의 필요성을 강조하는 국제기구의 정책안과 재보험사 및 전문연구기관의 연구 결과를 소개하여 기후변화 적응 방안으로 보험제도가 필수적임을 주장하고자 한다. 그리고 기후변화 적응을 위한 보험제도는 초대형 위험을 산정하고 위험을 효과적으로 분산할 수 있는 체계를 갖추어야 함을 주장하고자 한다. 또한 기후변화 재해와 저소득층간의 상관관계에 대해 고찰하고 그 대안을 제시하고자 한다. After signing the Kyoto Protocol for Climate Change Adaptation in 1997 as the Paris Climate Agreement concluded in 2015, it was an opportunity to inform the seriousness and urgency of adaptation to climate change. Climate change adaptation can be divided into disaster recovery caused by climate change and how to make slow. This article proposes the utilization of insurance as a risk-sharing and adaptation mechanism for extreme-scale natural disasters resulting from climate changes. It proposes how an insurance system should be established in order to accommodate climate change, and emphasizes its differences from existing insurance systems. The policy recommendations from key international organizations as well as the findings of re-insurance companies and related research institutions, which propose and indicate the necessity of insurance as a fiscal stabilization policy to adapt to climate changes, are introduced herein to demonstrate that insurance system is vital as a measure of climate change adaptation. Based on the recommendations from international organizations, the policy implementations and legislations of other countries, and the research from specialized research institutions and the insurance industry, this dissertation demonstrates the correlation between natural disasters caused by climate change and the degree of damages suffered by lower-income people. Accordingly, re-insurance, public-private joint insurance and micro-insurance are proposed as alternatives to the current problem.

Soo-Gon Han,Jung-Ho Huh 서울시립대학교 도시과학연구원 2008 도시과학국제저널 Vol.12 No.2

Cities all over the world have been warming up in the summer over the years. Seoul, the capital of Korea, is also an example of a city which has been transformed into an urban heat island. Green areas produce social, economical, and environmental benefits in highly populated urban areas. This study is to investigate the micro-climate changes and urban-scale cooling load reduction by the recently restored Cheonggye stream, also known as Cheonggyecheon, in Seoul. Since the urban developments of the 1950’s, the Cheonggye stream, located in central Seoul, has been covered with pavement and concrete overpass structures for over 50 years. A lot of surrounding buildings, traffic, and people caused the Cheonggye stream area to get hotter than other districts. For the urban environmental renovation, the 5.84 km-long stream was restored in September 2004. Since the restoration, the ecosystem in the center of Seoul has been reviving. This simulation study analyzes the micro-climate changes in the restored Cheonggye stream and its surroundings by using Envi-Met, a microclimate model designed to simulate the surface-plantair interactions in an urban environment. We employed TRNSYS to estimate the urban-scale cooling load reduction by using the output data from the Envi-Met simulation. The results indicated that the cooling benefits of the restored stream areas are promising in the locations where the environment was restored.

이태준(Lee, Taejun(David)) 한국광고홍보학회 2017 한국광고홍보학보 Vol.19 No.1

본 연구에서는 중앙 정부에 속해 있는 공무원의 사내 커뮤니케이션, 조직ᐨ공중 관계 관리 전략의 시사점을 발굴하기 위해 미시적 경계 확장 커뮤니케이션 모델을 활용하여 공무원 간 관계의 질과 조직과 관련된 개인별 전략 커뮤니케이션 행위의 연관성을 검증하였다. 그리고 이에 영향을 미칠 수 있는 조직 특성 요인들로 창조적 기풍, 조직 투명성, 커뮤니케이션 대칭성의 구조적 관계와 효과를 이론적 모형을 설정하여 분석하였다. 결과를 통해 공무원 간 관계의 질이 높게 형성될수록 공무원 스스로 조직을 위해 내부 공중 및 외부 공중과 긍정적이고 건설적인 커뮤니케이션 행위를 증진시키는 것으로 나타났다. 그리고 공무원 간 관계의 질은 창의적 기풍, 조직 투명성, 커뮤니케이션 대칭성이 공무원 개인의 전략적 커뮤니케이션 행위에 미치는 영향에 매개적 역할을 하는 것으로 나타났다. 또한 본 연구에서는 공무원 간 관계의 질만큼이나 관리자급의 변혁적 리더십도 공무원 개인의 전략적 커뮤니케이션 행위를 활성화시키는 것으로 나타났다. 본 연구는 공공 인재 관리제도 개선과 공무원 역량 강화 혁신 차원에서 공무원 소통과 공중 관계 관리 능력을 강화하기 위한 전략적 함의와 이론적 준거점을 제시하고 공공거버넌스의 질을 제고할 수 있는 정부기관 사내 커뮤니케이션 방향성을 논의하였다. Based on a conceptual model of government officers’micro-boundary spanning (i.e., non-designated persons’voluntary communication behaviors to disseminate positive information for one’s organization, collect pertinent organization-related information from internal and external stakeholders and share obtained strategic information with internally relevant persons of the organization), this article is to test the effects of three organizational traits ᐨ climate for creativity, transparency in organization, and communication symmetry on quality of relationship and micro-boundary spanning. In this study, transformational leadership is posited as an antecedent variable to the effects of micro-boundary spanning among government officers. A survey research was conducted with 450 government officers in Korea. Findings suggest that the quality of government officers’relationships can lead to a greater likelihood of performing micro-boundary spanning in and around the organization as the three organizational factors become well-established. In a similar vein, managers’transformational leadership can also be a meaningful driver of promoting micro-boundary spanning as the organizational climate is innovative and adaptive to creativity. The author discusses important theoretical and managerial implications regarding the role of government officers’internal communication and organization-public relationship in building and sustaining socio-cultural assets and individual capacity in government organizations.

Precision monitoring of radial growth of trees and micro-climate at a Korean Fir (Abies koreana Wilson) forest at 10 minutes interval in 2016 on Mt. Hallasan National Park, Jeju Island, Korea

Kim, Eun-Shik,Cho, Hong-Bum,Heo, Daeyoung,Kim, Nae-Soo,Kim, Young-Sun,Lee, Kyeseon,Lee, Sung-Hoon,Ryu, Jaehong The Ecological Society of Korea 2019 Journal of Ecology and Environment Vol.43 No.2

To understand the dynamics of radial growth of trees and micro-climate at a site of Korean fir (Abies koreana Wilson) forest on high-altitude area of Mt. Hallasan National Park, Jeju Island, Korea, high precision dendrometers were installed on the stems of Korean fir trees, and the sensors for measuring micro-climate of the forest at 10 minutes interval were also installed at the forest. Data from the sensors were sent to nodes, collected to a gateway wireless, and transmitted to a data server using mobile phone communication system. By analyzing the radial growth data for the trees during the growing season in 2016, we can estimate that the radial growth of Korean fir trees initiated in late April to early May and ceased in late August to early September, which indicates that period for the radial growth was about 4 months in 2016. It is interesting to observe that the daily ambient temperature and the daily soil temperature at the depth of 20 cm coincided with the values of about 10 ℃ when the radial growth of the trees initiated in 2016. When the radial growth ceased, the values of the ambient temperature went down below about 15 ℃ and 16 ℃, respectively. While the ambient temperature and the soil temperature are evaluated to be the good indicators for the initiation and the cessation of radial growth, it becomes clear that radii of tree stems showed diurnal growth patterns affected by diurnal change of ambient temperature. In addition, the wetting and drying of the surface of the tree stems affected by precipitation became the additional factors that affect the expansion and shrinkage of the tree stems at the forest site. While it is interesting to note that the interrelationships among the micro-climatic factors at the forest site were well explained through this study, it should be recognized that the precision monitoring made possible with the application of high resolution sensors in the measurement of the radial increment combined with the observation of 10 minutes interval with aids of information and communication technology in the ecosystem observation.

The thermal insulation value of clothing depends upon the physical properties of the fabric, and amount of body surface area coverde, and the air space between the body and the clothing. The insulation of clothing system can be measured using an electrically-heated manikin in thermal equilibrium with its surroundings. This study is to examine the regional thermal resistance of dust-free garment in the climate chamber, 23±1℃ and 50±5%RH, has been determined by a sweating thermal manikin. Dust-free garment ensemble were composed of hood, mask, boots, gloves, dust-free inner wear and coveralls garb. Measured items were regional thermal resistance and micro-climate within colthing. The investigation presented a preparatory effort to assemble research and information pertaining to the dust-free garment function and identify and categorize garment design, fabrication of currently worn and desired future garment. The results were as follows; 1. The regional thermal resistance (℃/W/m²) of wearing dust-free garment on sweating thermal manikin were in the order of Abdomen >Chest > Trunt(front) > Back > Trunk(back)> Hip > Arm(right) > Leg(right) > Arm(left) =Leg(left). The variation coefficients(CV%) of regional thermal resistance was higher(85.8%) in dust-free garment than about 50% in one-piece dress and about 40% in sports wear. In case of the body, thermal resistance was lower in back sites than in front sites. 2. The regional temperature within clothing were in the order of Arm(right) > Chest > Abdomen= Hip > Lig(left) > Trunk(back) > Arm(left) > Back= Leg(right) = Trunk(front). In case of the body, temperature within clothing was higher in front sites than in back sites. And, the temperature sithin clothing was lower in leg parts than in arm parts generally. The other side, the humidity within clothing were in the order of Leg(left) > Arm(right) >Trunk(front) > Trunk(back) >Abdomen =Leg(right) > Back > Arm(left) > Hip > Chest. The regional humidity within clothing were the lowest in chest site 29.9% to 49.2% RH.

Micro-climate measurements and computational fluid analysis were conducted to use it as basic data for the preservation and management of the old house of Kim Myung-kwan, a traditional building that is National Folk Cultural Property No.26. As a result of the actual measurement, the temperature and humidity are relatively evenly distributed indoors unlike outdoors, but the temperature and humidity vary depending on the time change and the installation location in the outdoors. It was found that the temperature increases after dawn and the temperature varies depending on the installation position around 14:00–15:00, when the temperature becomes the highest. In particular, the temperature was high at the outdoor measurement point adjacent to the building and the fence. As a result of the computational fluid analysis, the temperature was high in the buildings and fences in the old house or in the area adjacent to the building, and it was about 1℃ higher than the surrounding area. In this area, it is judged that the thickening of wood will occur more severely than in other locations, and special preservation management is required.

Wood is one of the main materials of wooden building. Hanok also uses wood as its main component. Recently, Hanok continues to be built. Wood is affected by the climatic environment. The growth of decay bacteria is activated at more than 80% relative humidity. The microclimate environment and moisture content were measured for architectural cultural properties that have been maintained for a long time as a wooden building. The method analyzed the measured data by distinguishing between cloudy and sunny days. In the case of the old house, Anchae moisture content was higher than that of Sarangchae. This seems to be due to the narrow front yard or the planting of trees. The microclimate environment inside the house began to decrease in humidity from 8 am. According to the survey data, the relative humidity was less than 80% from 9 am when there was wind around 4-6 am. It appeared an hour earlier than in the absence of wind. As a result, the time interval for dehumidifying of wood was widened. Therefore, the wooden building is open to the front so there is airflow under the eaves during the daytime and wind in the morning appear to be alternatives in order to lower the moisture content.

As climate change becomes a reality, abnormal weather phenomena such as heat waves, cold waves and fine dust in cities are deepening, they are also affecting residential areas, which are the living places for urban residents. Low-rise residential areas account for 38.2 percent of the city"s total residential areas, and they are highly vulnerable to microclimate phenomena due to insufficient living infrastructure, such as green areas, and aging residential environments. Therefore, this study is intended to examine the seasonal phenomena of urban micro-climate in detail , which has the most direct effect on human life, in low-rise residential areas. Therefore, this study conducted on-site survey by measuring the elements related to microclimate that are felt throughout the year, such as temperature, wind speed and fine dust, during three seasons(summer, fall and winter) with hillside low-rise residential area in Dongjak-gu, Seoul as the study site. The results showed different characteristics of micro-climate depending on the topography, building shape, outer space composition, surface packaging, etc. In particular, due to the hillside and irregular housing arrangements in the northwest, the wind speed from the south has decreased, causing the heat in the target areas to stagnating. Based on these actual results, various methods of improving residential environment are needed to create a pleasant residential environment based on the analysis contents.
