현재 국내 액셀러레이터 시장에서 공공 액셀러레이터의 역할이 점차 확대되고 있다. 이에 따라 향후 정책의 수립을 위해 공공 액셀러레이터의 투자효과를 점검하고 그 타당성을 검증할 필요가 있다. 그러나 국내 액셀러레이터는 그 역사가 짧고 정량적인 자료가 공개되지 않고 있어 액셀러레이터에 관한 재무데이터를 활용한 정량적 연구가 부재한 것이 현실이다. 이에 본 연구는 공공 액셀러레이터의 투자가 스타트업에 미치는 효과를 확인하기 위해 실제 공공 액셀러레이터의 지분투자를 받은 스타트업의 재무데이터를 가지고 실증분석을 진행하였다. 2016년부터 2020년까지 5년간 공공 액셀러레이터가 투자한 112개 스타트업의 재무데이터를 사용하여 회귀분석을 진행하였다. 실증분석 결과 첫째, 공공 액셀러레이터의 초기투자가 스타트업에 대한 성장성과 수익성에 영향을 미치는 것으로 나타났다. 세부적으로 살펴보면 공공 액셀러레이터의 초기투자가 성장성 지표인 매출액 증가율과 총자산증가율에 정(+)의 영향을 미치는 것을 확인하였다. 둘째, 공공 액셀러레이터의 공동투자가 성장성보다는 수익성 지표인 매출액이익률에 유의한 정(+)의 영향을 미치는 것으로 나타났다. 본 연구를 통해 유의미한 결과를 보인 초기 스타트업에 대한 투자를 지속적으로 확대하고 공공 액셀러레이터의 강점인 지원 사업을 결합한다면 스타트업의 성장에 더욱 큰 힘이 될 것으로 생각한다. 본 연구를 통하여 공공 액셀러레이터의 투자 성과를 확인하였으므로 향후 공공 액셀러레이터 사업은 민간 액셀러레이터들의 미흡한 부분을 보완함과 동시에 민간과의 공동투자를 통해 스타트업의 성과를 제고하는 방향의 정책 추진이 필요한 것으로 판단된다.

This study calculated monthly and sectoral (for industry, energy industry, transport, residential, commercial and public sectors) greenhouse gas (GHG) emissions of Seoul, Korea from 1999 until 2009 with following the IPCC 2006 Guideline for National Greenhouse Gas Inventories through an analysis on available monthly data of fossil fuel and electricity consumption for the period. The time series analysis showed that GHG emissions had significant cyclical pattern season by season with the highest peak in August and the lowest peak in January throughout the period. The analysis on monthly and sectoral energy consumption showed that residential, commercial and public sectors had emitted about 65% of total GHG emissions of Seoul and had consumed more energy in winter for heating. About 30% GHG of Seoul was emitted from transport sector but its monthly energy consumption showed irregular pattern and it consumed 80% petroleum (in 2009) of Seoul. Hopefully together with further study on this subject, it is expected that this study can be used as basic data for various research regarding Greenhouse gas baseline emission, energy consumption pattern and estimation for future GHG emission of Seoul.

The purpose of this study was to investigate work stress and identify the various factors affecting stress in married women in working manufacturing industries. Data were collected between March 31 and June 28, 2003 from 266 married women working in 10 manufacturing industries in Korea. The self-administered questionnaire included general characteristics. social support, and work stress. The data were analyzed using descriptive statistics, t-test, ANOVA, and Cronbach's alpha. SPSS/win 11.0 was used to assist analysis. The results of the study are as follows: 1. Scores for work stress in the field of sub-categories 2. Perceived work stress was significantly different according to salary, behavior type, discomfort related to menstruation, consumption, duty type, job stability, weekly work time and family, 3. Social support had a significant negative relationship with work stress. Accordingly, stress management for married working women will be more successful if interventions not only address each person's unique needs, for example, control of perimenstrual discomforts and health behavior change, but also are accompanied by organizational management strategies and policies, for example, improvement of work environment and nursery facilities.

Angiogenesis is one of the essential processes that occur during wound healing. It is responsible for providing immunity as well as the regenerative cells, nutrition, and oxygen needed for the healing of the alveolar socket following tooth extraction. The inappropriate removal of formed blood clots causes the undesirable phenomenon of alveolar osteitis (AO) or dry socket. In this review, we aimed to investigate whether enhanced angiogenesis contributes to a more effective prevention of AO. The potential pro- or anti-angiogenic activity of different materials used for the treatment of AO were evaluated. An electronic search was performed in the PubMed, MEDLINE, and EMBASE databases via OVID from January 2000 to September 2016 using the keywords mentioned in the PubMed and MeSH (Medical Subject Headings) terms regarding the role of angiogenesis in the prevention of AO. Our initial search identified 408 articles using the keywords indicated above, with 38 of them meeting the inclusion criteria set for this review. Due to the undeniable role of angiogenesis in the socket healing process, it is beneficial if strategies for preventing AO are directed toward more proangiogenic materials and modalities.

Background: Nurses play an important role in preventive medicine because they represent the largest sector of health professionals. This role is very crucial in developing countries, which are going through rapid societal and economic changes, associated with a rising burden of cancers due to different risk factors. The current study aimed to compare health awareness between nurses and healthy women regarding preventive gynecological examinations and to answer the question - can nurses make a difference in women's health? Materials and Methods: This cross sectional research included a total of 150 women, 70 nurses and 80 healthy women, randomly selected. Data were collected in 2014 in Vlora city through a self-administered questionnaire that assessed different variables about preventive gynecological examinations. Results: Cervical screening rates were 20.3% and 41.8%, respectively, for nurses and healthy women, despite the former having a statistical significant greater knowledge of risk factors and symptoms. Conclusions: Even if the health awareness of nurse participants can be considered good, they need themselves to increase participation rates in cervical screening if they are to provide role models for health education/promotion addressing misconceptions and barriers.

Korea successfully achieved energy independence in the shortest period of time from being the poorest country in terms of energy 50 years ago through steady development of nuclear technology. In the past, the nuclear industry has been driven through government-centered policy development, public institution-based research, and industrial facility and infrastructure construction. Consequently, South Korea became a nuclear energy powerhouse exporting nuclear power plants to the UAE, surpassing the level of domestic technological independence. However, in recent years, the nuclear industry in Korea has experienced a decline in new plant construction since the Fukushima accident in Japan, which caused changes in public perspectives regarding nuclear power plant operation, more stringent safety standards on the operation of nuclear power plants, and a shift in governmental energy policy. These changes are expected to change the domestic nuclear industry ecosystem. Therefore, in this study, we investigate the priority of technology development investment from the perspective of experts in private nuclear power companies, shifting the focus from government-led nuclear R&D policies. To establish a direction in nuclear technology development, a survey was conducted by applying an analytic hierarchy analysis to experts who have worked in nuclear power plants for more than 15 years. The analysis items of focus were the 3 attributes of strategic importance, urgency, and business feasibility of four major fields related to nuclear energy: nuclear safety, decommissioning, radioactive waste management, and strengthening industrial competitiveness.

It is clear that so called 1% law " in Korea has been established to enhance the quality of urban environment. However, after more than 10 years of its enforcement, environmental sculptures installed in accordance with the "1% law" are even being called as "sculptural pollution". This research was a part of a study on the environmental sculptures for the enhancement of the quality of urban environment. The purpose of this study was to investigate problems inherent in the outdoor space as places of environmental sculptures installed in accordance with "1% law". The following facts were found from the analysis of the relationship between 223 environmental sculptures and their surrounding environment from the viewpoint of spatial organization through field surveys. 1. 88.3% out of 223 environmental sculptures were located on ' 'public space' on study sites 2. 69.1% were placed on 'green' 3. 80.7% of 'green' were either 'point' types or 'line' types 4. 85.2% were under 5m in the longest dimension. The implication of this study is that "1% law" in Korea has been applied to only buildings in private sector where most outdoor space area in unadequate physical and spatial conditions to install diverse forms of environmental sculptures. Further studies must be carried out to install environmental sculptures in public open pace as an alternative by amending "1% law".

The purpose of this study is to present an evaluation model to measure the clarification level of stakeholder requirements of public sector software projects in the Republic of Korea. We tried to grasp the quality of proposal request through evaluation model. It also examines the impact of the level of stakeholder requirements on the level of system requirements. To do this, we analyzed existing research models and related standards related to business requirements and stakeholder requirements, and constructed evaluation models for the system operation concept documents in the ISO/IEC/IEEE 29148. The system operation concept document is a document prepared by organizing the requirements of stakeholders in the organization and sharing the intention of the organization. The evaluation model proposed in this study focuses on evaluating whether the contents related to the system operation concept are faithfully written in the request for proposal. The evaluation items consisted of three items: 'organization status', 'desired changes', and 'operational constraints'. The sample extracted 217 RFPs in the national procurement system. As a result of the analysis, the evaluation model proved to be valid and the internal consistency was maintained. The level of system operation concept was very low, and it was also found to affect the quality of system requirements. It is more important to clearly write stakeholders' requirements than the functional requirements. we propose a news classification methods for sentiment analysis that is effective for bankruptcy prediction model.
