강병준,최조순 한국정책분석평가학회 2013 政策分析評價學會報 Vol.23 No.2

사회적 기업은 사회적 목적과 경제적 목적을 동시에 추구하는 조직으로 이해되고 있다. 그러나 사회적 기업은 혼성조직의 특성으로 인하여 사회적 목적과 경제적 목적 사이에 상충관계가 발생한다. 본 연구는 사회적 기업의 조직형태에 따라 사회적 성과와 경제적 성과 간의 영향 관계를 밝혀내는 것이다. 이를 위해 서울형 사회적 기업을 전통적 사회적 기업과 비전통적 사회적 기업으로 구분하였다.분석결과 서울형 사회적 기업은 전통적 사회적 기업과 비전통적 사회적 기업 간의 사회적·경제적 성과에는 차이가 없는 것으로 나타났다. 또한 서울형 사회적 기업의 사회적 성과(취약계층 고용비율)는 경제적 성과(기업수익률)에 부(-)의 영향을 미치는 것으로 나타났다. 그리고 서울형 사회적 기업의 조직형태는 사회적 성과와 경제적 성과 간의 조절변수로 작용하는 것으로 나타났다. 이러한 결과는 서울형 사회적 기업 정책이 지역적인 특성이나 조직형태를 고려한 것이기 보다는 탑다운 방식의 획일적 기준에 따라 정책이 집행되고 있는 결과를 나타내는 것이다.따라서 서울형 사회적 기업이 지속가능하기 위해서는 새로운 성과지표 개발, 사회적 기업의 선순환 체계 구축, 도시형이나 농촌형과 같은 지역별 특성과 조직형태를 고려한 맞춤형 사회적 기업 정책, 서울시와 자치구, 중간지원 조직, 일반 기업, 시민사회가 협력할 수 있는 사회적 기업 생태계 조성이 필요하다.

We have studied methods to save Si source during the fabrication process of crystalline Si solar cells. One way is to use a thin silicon wafer substrate. As the thickness of the wafers is reduced, mechanical fractures of the substrate increase with the mechanical handling of the thin wafers. It is expected that the mechanical fractures lead to a dropping of yield in the solar cell process. In this study, the mechanical properties of 220-micrometer-solar grade Cz p-type monocrystalline Si wafers were investigated by varying saw-damage etching conditions in order to improve the flexural strength of ultra-thin monocrystalline Si solar cells. Potassium hydroxide (KOH) solution and tetramethyl ammonium hydroxide (TMAH) solution were used as etching solutions. Etching processes were operated with a varying of the ratio of KOH and TMAH solutions in different temperature conditions. After saw-damage etching, wafers were cleaned with a modified RCA cleaning method for ten minutes. Each sample was divided into 42 pieces using an automatic dicing saw machine. The surface morphologies were investigated by scanning electron microscopy and 3D optical microscopy. The thickness distribution was measured by micrometer. The strength distribution was measured with a 4-point-bending tester. As a result, TMAH solution at $90^{\circ}C$ showed the best performance for flexural strength.

Sewer deterioration models are needed to forecast the remaining life expectancy of sewer networks by assessing their conditions. In this study, the serious defect (or condition state 3) occurrence probability, at which sewer rehabilitation program should be implemented, was evaluated using four probability distribution functions such as normal, lognormal, exponential, and Weibull distribution. A sample of 252 km of CCTV-inspected sewer pipe data in city Z was collected in the first place. Then the effective data (284 sewer sections of 8.15 km) with reliable information were extracted and classified into 3 groups considering the sub-catchment area, sewer material, and sewer pipe size. Anderson-Darling test was conducted to select the most fitted probability distribution of sewer defect occurrence as Weibull distribution. The shape parameters (β) and scale parameters (η) of Weibull distribution were estimated from the data set of 3 classified groups, including standard errors, 95% confidence intervals, and log-likelihood values. The plot of probability density function and cumulative distribution function were obtained using the estimated parameter values, which could be used to indicate the quantitative level of risk on occurrence of CS3. It was estimated that sewer data group 1, group 2, and group 3 has CS3 occurrence probability exceeding 50% at 13th-year, 11th-year, and 16th-year after the installation, respectively. For every data groups, the time exceeding the CS3 occurrence probability of 90% was also predicted to be 27th- to 30th-year after the installation.

Sewer deterioration models can offer important information on prediction of future condition of the asset to decision makers in their implementing sewer pipe networks management program. In this study, Markov chain model was used to estimate sewer deterioration trend based on the historical structural condition assessment data obtained by CCTV inspection. The data used in this study were limited to Hume pipe with diameter of 450 mm and 600 mm in three sub-catchment areas in city A, which were collected by CCTV inspection projects performed in 1998-1999 and 2010-2011. As a result, it was found that sewers in sub-catchment area EM have deteriorated faster than those in other two sub-catchments. Various main defects were to generate in 29% of 450 mm sewers and 38% of 600 mm in 35 years after the installation, while serious failure in 62% of 450 mm sewers and 74% of 600 mm in 100 years after the installation in sub-catchment area EM. In sub-catchment area SN, main defects were to generate in 26% of 450 mm sewers and 35% of 600 mm in 35 years after the installation, while in sub-catchment area HK main defects were to generate in 27% of 450 mm sewers and 37% of 600 mm in 35 years after the installation. Larger sewer pipes of 600 mm were found to deteriorate faster than smaller sewer pipes of 450 mm by about 12 years. Assuming that the percentage of main defects generation could be set as 40% to estimate the life expectancy of the sewers, it was estimated as 60 years in sub-catchment area SN, 42 years in sub-catchment area EM, 59 years in sub-catchment area HK for 450 mm sewer pipes, respectively. For 600 mm sewer pipes, on the other hand, it was estimated as 43 years, 34 years, 39 years in sub-catchment areas SN, EM, and HK, respectively. 하수관로 열화모델은 하수관망을 관리하는 의사결정자에게 자산의 미래 상태 예측에 대한 중요한 정보를 제공할 수 있다. 본 연구에서는 CCTV 조사를 통해서 확보한 구조적 상태평가 이력자료를 기반으로 마르코프 연쇄 모델을 이용하여 하수관로의 노후도를 추정하였다. A시의 3개 배수분구에서 1998-1999년과 2010-2011년에 CCTV 조사에 의해 수집된 관경 450 mm와 600 mm의 흄관 자료를 이용하여 분석하였다. EM 배수분구의 450 mm 관로와 600 mm 관로에서 주요 결함 발생이 다른 두 배수분구보다 빠르게 발생하는 것으로 나타났다. 관로 설치 이후 35년이 지난 시점에는 450 mm 관로의 약 29%, 600 mm 관로의 약 38%가 주요 결함이 발생했으며, 100년 후에는 각각 62%와 74%의 관로가 주요 결함으로 관로 기능을 상실하는 수준으로 나타났다. 관로설치 35년 후, SN 배수분구는 450 mm 관로의 약 26%, 600 mm 관로에서 약 35%, HK 배수분구에서는 450 mm 관로의 약 27%, 600 mm 관로에서 약 37%의 주요 결함이 발생한 것으로 예측되었다. 또한 600 mm 관로가 450 mm 관로보다 평균 12년 정도 빨리 기능 저하가 일어나는 것으로 나타났다. 한편, 관로의 주요 결함등급 비율을 40%로 설정하여 관로의 유효사용수명으로 적용할 경우, 450 mm 관로는 SN배수분구에서 60년, EM배수분구에서 42년, HK배수분구 59년이며, 600 mm 관로에서는 각각 43년, 34년 39년으로 나타났다.

Large spatial structural system technology has been developed since the mid-20th century by applying technologies to various types of large spatial structures. In architecture, design can greatly improve the value of the structure. However, each large spatial structure has its own shape and size, making it difficult to apply directly to the design of large spatial structures, as there are many unpredictable elements, unlike ordinary ramen structures. In this paper, we aim to classify large spatial structures with different shapes around the world into five categories: gable, barrel, circular, oval, and stadium, and analyze the trends in large spatial structure design to explore related technology development plans in the future. The Lucas Oil Stadium was able to create a familiar and classic beauty using a gable roof, which is an advantage of simplicity and efficiency, and the New Safe Configuration was built with sliding barrel roofs for the safety of workers. Busan Asiad Main Stadium chose a circular shape that is advantageous for large spatial formation where thin members are used for the purpose of lightening steel truss structures, while the Joe & Rika Mansueto Library chose a functionally excellent oval method to secure space. It was concluded that large spatial structures require appropriate building technology depending on the purpose of use and the form of expression.

국제건축설계공모전 운영의 문제점과 개선방향에 관한 연구 - 2004년 낙동강 에코센터 국제건축설계공모전 사례를 통해 -

강병준 대한건축학회지회연합회 2017 대한건축학회연합논문집 Vol.19 No.6

The economic value and socio-cultural value of specialized buildings have a great impact. The value of aesthetic architectural design led to the creation of added value such as an increase in the value of assets and an increase in the number of foreign tourists and visitors. Therefore, many countries and cities have made great efforts to make urban image making through specialized buildings. But exceptional architecture starts with designers with creative and technically superior competencies. If the designer's competence and the legal system and regulations to support it do not have the triple digits, excellent architecture will not be able to see the light of the world. If you do not have all the details such as purpose of construction design, specialization plan, space plan, and related regulations and technical review to be presented to the participants for the design competition, you should not select ‘work’, select ‘person’. The purpose of this study is to find out the problems and find alternatives through the case of Nakdong River Eco Center. In the case of the Nakdong River Eco Center, the design process based on the elected design was not able to be constructed according to the design of the wooden material according to the law. The problems at the Nakdong River Eco Center International Design Competition can be summarized as follows. First of all, it is a problem in the operation process such as making design guidelines by non-experts. If the relevant laws and regulations were thoroughly reviewed and the design guidelines for the public offering were made and presented after the technical review was completed, the design using wood would not have been submitted in the first place. Next is the unilateral process of design change. If design changes were inevitable due to the restriction of related laws, designers need to be actively involved in the design change so as not to undermine the design philosophy and concept of the designer. If public buildings built with enormous cost can not match the original philosophy and function, it can also be a social loss. In this study, the following three alternatives were proposed for a more efficient and high-level operation plan of the international architectural design contest. First, it is necessary to secure the public power by including the regulations on the drafting of the guidelines for the international architectural design competition, which is based on actual construction, in the ‘Building Service Industry Promotion Act’. Second, the level of awareness of stakeholders is enhanced through education. Third, it is necessary to build an integrated database for the international architectural design competition and to build a system that manages already completed projects, present and planned projects as a whole. In accordance with the WTO opening principle of architectural design market, the domestic architectural design market is also in need of in-depth discussion and research on the planning and operation of architectural competition in accordance with global standards and guidelines.

강병준 한국정책개발학회 2011 정책개발연구 Vol.11 No.1

In Korea, social enterprises have been received attention in a subject of social integration, social problem solving and polarization. To suggest policy alternatives about the enhancement of social enterprises, interviews were conducted with stakeholders of the social enterprise. The result of analysis shows that the high quality growth of social enterprises through the collaborative effort of government, business, civil society and social enterprises is required. The government needs to ease the current stringent standards for certification and to modify the enterprise promotion act to avoid inconsistency with other laws. Also, diversification of financial support and e-government system is required. In addition, the role of the civil society and government is essential to raise awareness of social enterprises among people. Finally, the corporate sector should diffuse the business ethics, strengthen the cooperation and network between businesses and social enterprise, and support the system for reinforcing the internal organization of social enterprise management. 최근 한국사회에서 사회적 기업은 사회문제 해결과 양극화 해소, 사회통합의 주체로서 주목받고 있다. 본 논문은 사회적 기업의 이해관계자들을 대상으로 사회적 기업의 현황, 정부 부문, 시민사회 부문, 기업 부문에 대한 인터뷰 조사를 실시하여 사회적 기업 활성화를 위한 정책적 대안을 도출하는 것이다. 인터뷰 분석 결과 전반적인 사회적 기업 활성화를 위해서는 정부와 기업 그리고 시민사회의 협력적 노력을 통한 사회적 기업의 질적 성장이 요구된다는 것을 밝혀내었다. 정부 부문에서는 현재의 엄격한 사회적 기업 인증기준의 완화, 사회적 기업 육성법과 다른 법령과의 유기적인 정비, 재정지원의 다양화, 전자정부시스템 도입이 필요하다. 다음 시민사회 부문에서는 사회적 기업에 대한 인식제고를 위한 시민사회의 노력과 정부의 정책적 노력이 요구된다. 마지막으로 기업 부문에서는 기업윤리의 확산, 일반 기업과 사회적 기업의 협력․네트워크 강화, 사회적 기업의 내부 조직관리 강화를 위한 제도적 지원이 확대되어야 한다.
