The member nations of European Union and some states levy the CT(Carbon tax) which approximately 3~150 US dollar per ton of CO2. A few years after, South Korea government will have to levy the CT to the fossil energy consumption fields for reduction of GHG because South Korea will not evade the Annex-Ⅰlevel at 2013. For the reduction of CO2 in the building, this paper were a preliminary study which the estimation on the CT influence of the energy cost in the use groups of building. It was using by the IPCC GHG estimation rule, the modification data of 2005 Energy Census in South Korea, and the consideration of the CT levy level of other nations. The influence of CT on the building energy cost was different level through the building use groups because each building use group consumes different level of the running energy and different energies as petroleum, city gas, electric power. In conclusion, if CT will be levied 10,000~15,000 won per ton of CO2 in South Korea, the annual building energy cost(Won/㎡year) will rise up as the follows; the average of all buildings is 841~12,622; the private office is 763~11,450; the public office is 816~12,242; the department is 1,965~29,469; the store is 1,806~27,090; the school is 592~8,876; the institute is 1,807~27,106; the hotel is 1,808~27,127; the hospital is 1,675~25,124; the telephone office is 2,102~31,532; the apartment is 437~6,558; the others building is 1,463~21,941.

정근주,원이중 한국중소기업학회 2023 中小企業硏究 Vol.45 No.2

This study analyzed the policy effectiveness by classifying the government's SME(small to medium‐sized enterprise) policy analysis research literature listed in the Korean Citation Index from 2002 to 2021 by policy target, policy tool, and policy performance. If most of the existing SME policy studies were analyzes focusing on specific policies, regions, or industries, this study divides 317 papers into 6 policy performances(management performance, economic performance, technological performance, employment performance, and establishment induction performance, policy satisfaction) and evaluates them. Therefore, it is meaningful in that it examined the effect of SME policies from an integrated point of view. As a result of an overview of the research literature, first, in studies targeting small and medium-sized enterprises, the proportion of positive research is high, but policies for detailed targets such as small businesses are evaluated as having low effectiveness. In the case of policies confined to industries rather than regions, the proportion of studies with positive evaluations was higher. Second, the research literature was analyzed based on policy tools. In the case of support limited participation, informatization, surety, and package policies, the proportion of positive evaluation was high, but the government-led management support policy has mixed positive and negative evaluations because it does not meet the needs of companies. Finally, SME policy performance accounted for the highest proportion in economic performance. In conclusion, policies aimed at clear targets, such as small business policies and management support, but which are ineffective or do not fit the needs of companies, should be reformed to suit the market environment. In addition, policies that are sure to be effective, such as industry-tailored policies, surety, certification, and informatization, must be actively supported. In addition, since SME policies have a very high effect on the overall macro economy, SME policies should move forward to have a positive impact on the overall industrial ecosystem through technological innovation, not just beneficiaries. 본 연구는 2002년~2021년 동안 한국학술지인용색인에 등재된 정부의 중소기업 정책 분석 연구 문헌을 정책 대상·수단·성과 별로 구분하여 정책 실효성을 분석 및 정리했다. 기존 중소기업 정책 연구의 대부분이 특정한 정책, 지역 또는 산업에 초점을 맞춘 분석이었다면, 본 연구는 317개의 논문을 각각의 대상 수단 외에도 6개의 정책성과(경영성과, 경제성과, 기술성과, 고용성과, 창업성과, 만족도)로 나누어 평가함으로써 통합적인 관점에서 중소기업정책의 효과를 살펴보았다는 점에서 의의가 있다. 연구 문헌들을 개관해본 결과, 첫 번째로 중소기업 전체를 대상으로 한 정책의 효과가 대상을 특정한 정책에 비해 실효성이 높은 것으로 확인된다. 또한 지역보다 산업에 국한된 정책의 경우 긍정적인 평가의 연구 비중이 높았다. 두 번째로 정책수단은 크게 재무지원과 비재무 지원으로 구분할 수 있는데 재무지원에서 자금지원이 가장 많이 활용되고 있으며, 대표적인 비재무지원인 정부 주도로 지원되는 정책이 기업의 수요를 따라가지 못해 복합적인 평가 비중이 높다. 마지막으로 중소기업 정책성과는 정책목표에 맞춰 구분하여 살펴보았는데, 중소기업 정책이 단기적으로는 복합적일 수 있지만, 기업에서 산업, 경제로 확대될수록 파급효과가 커지는 것으로 확인할 수 있었다. 한국 경제에서 중소기업이 차지하는 역할은 더욱 확대될 것이므로 수요(needs)에 맞지 않는 정책들은 시장환경에 맞게 개편되어야 하며, 산업 맞춤형 정책, 보증, 인증, 정보화와 같이 효과성이 확실한 정책들은 적극적으로 지원해야 한다. 또한 중소기업정책은 거시경제 전반에 미치는 효과가 매우 높게 나타나기 때문에, 중소기업정책이 수혜기업에만 머물지 않고 기술혁신을 통해 전반적인 산업 생태계에 긍정적 영향을 미칠 수 있도록 나아가야 할 것이다.

The GHG(Green House Gases) emitted by the building energy consumption was a serious problem to the global warming because the building energy consumption ratio was approximately 30∼40% to the all energy consumption. Recently, a lot of the building energy source Heat Pump installed for the air conditioning, the domestic water supply. Generally, the Heat Pump is classified the EHP(Electric Air-sourced Heat Pump), the GHP(Gas Engine Driven Air-sourced Heat Pump), the GSHP(Electric Ground-Sourced Heat Pump). As known, the reducing performance of GHG of GSHP is approximately 20∼ 25% higher than EHP and GHP. However, the published quantitative study on the performance of reducing annual GHG was rare case. Therefore, the purpose of this study is comparison of the GHG on EHP, GHP, GSHP based on conversion data of annual energy consumption of GSHP in the case building. According to this study, the GSHP GHG emission is 18.1% lower than EHP, 8.1% lower than GHP. (In this study, the fossil fuel GHG emission estimate due to the IPCC GHG estimation rule as well as the electric power GHG emission estimate due to the electric power production ratio of fuels, the efficiencies of power plant of fuels, the efficiency of electric power distribution in Korea. The case building is a child-care center of which all area is 2,119.2㎡ and GSHP capacity is 90RT and the location is Seoul Korea.)

고정하중 및 공사비 경감과 관련하여 체육관 등의 큰 공간에 경량 철골 및 금속재 지붕재료가 사용되고 있다. 이러한 금속 지붕은 매끄러운 표면에 의하여 햇빛 경면반사를 일으키고 이에 의하여 인근지역에 불능현휘를 야기 시킨다. 이러한 현상은 인근 건물에 과열, 눈 건강 위해, 열적 불쾌적, 냉방부하 증가와 같은 환경적 문제를 발생시킨다. 본 연구는 이러한 금속 지붕의 햇빛 경면반사를 감소시키기 위하여 여러 가지 도장 샘플을 제작한 다음 각각의 햇빛 반사 휘도를 측정하고 가장 효과적인 감소방법을 찾고자 한다. 본 연구에서 9개의 샘플 가운데 7개의 샘플은 불능현휘를 발생시킬 수 있는 수준의 경면반사 휘도가 나타났다. 반면 규사를 혼합하여 표면을 매우 거칠게 구성한 2개의 샘플에서 확산반사가 발생됨에 따라 확연히 경면반사를 감소시킬 수 있었다. A lightweight building envelope, such as metal roofing, is widely used to reduce the dead load and cost of construction when designing gymnasiums and other large buildings. The specular reflection of sunlight from a gymnasium roof with a highly reflective metal material can result in disability glare. The reflective phenomenon generates environmental problems, such as the overheating of the building materials, vision problems, discomfort in thermal environment and the increase of cooling load in the neighborhood. The aim of this research is to reduce the specular reflection of sunlight from a metal roof using a rough coating, such as paint mixed with silica sand. The brightness of the sun’s reflection on a metal roof of model gymnasium was investigated. The research was carried out by using 9 samples of coating material and measuring the level of brightness of the reflected sunlight under natural sunshine condition. As the result, the disability glare occurred on 7 samples without rough surface and the diffusing reflection occurred on 2 sample surfaces with rough silica mixed coating.

추운 환경에서 발열의복을 착용한 건강한 피험자의 온열반응

정근주 대한건축학회지회연합회 2011 대한건축학회연합논문집 Vol.13 No.1

겨울철 대형 공장이나 외부 작업장에서 작업자들은 서늘하거나 추운환경에 노출되어 있다. 이들을 위하여, 최근 몇몇의 제조사들은 리튬이온 축전지와 가열기를 부착한 발열의복(HV)을 판매하고 있다. 그러나 발열의복을 작업자가 착용하였을 때, 그들의 온열감각이 상승되거나 그렇지 않은 점에 대하여 알려진 바가 없다. 그리고 이 옷에 관한 온열감각 평가 및 기초자료 관련 연구를 찾아보기 어렵다. 이에 따라, 본 연구는 약간 서늘한, 서늘한, 추운 온열환경으로 조절된 인공기후실에서 발열의복의 온열감각 및 육체적 온열반응을 실험하였다. 본 연구는 6명의 발열의복 착용 피험자를 대상으로 그들의 상반신, 하반신, 전신에 관한 세부분의 주관적온열반응평가(TSV; ISO 7730, 7척도), 평균피부온도(MST; ISO 9886)를 측정하였다. 본 연구에서, 발열의복 착용 시 상반신 TSV는 미착용 시보다 약간의 차이로 증가하였다. 이 차이는 약간 서늘한 환경에서 0.75, 서늘한 환경에서 0.83, 추운 환경에서 1.00으로 나타났다. 이와 대조하여, 착용 시 하반신 TSV는 미착용 시의 TSV와 비슷하게 나타났다. 발열의복 착용 시 피험자의 등 피부온도 상승을 통하여 MST는 미착용 시 보다 약간 증가하였다. 이 차이는 약간 서늘한 환경에서 0.46℃, 서늘한 환경에서 0.42℃, 추운 환경에서 0.26℃로 나타났다. 결론적으로 발열의복은 상반신의 온열감각을 약간 상승시킬 수 있었으나, 하반신에서는 그러하지 못하였다. 앞으로 하반신 온열감각 개선에 관한 후속 연구가 필요할 것으로 생각된다.
