스타트업 생태계 활성화를 위한 액셀러레이터의 역할에 대한 큰 잠재력을 인정한 대한민국 정부는 2016년 일명 액셀러레이터법을 도입하였으며, 이에 힘입어 최근 등록된 액셀러레이터는 136개 수준으로 활성화 되었다. 액셀러레이터는 발원지인 미국뿐 아니라 유럽에서도 부흥하고 있는 등 세계적으로 주목받고 있지만 현재까지 액셀러레이터에 대한 선행 연구는 많지 않은 것이 사실이다. 국내에서는 액셀러레이터 법제화 이후에도 액셀러레이터의 연구는 극소수에 불과해 액셀러레이터에 대한 다양하고 심도 있는 학문적 연구가 필요한 상황이다. 스타트업과 액셀러레이터 간의 관계에 대한 객관적인 정보는 액셀러레이터를 통한 성공적인 스타트업 지원에 필수적이다. 아직 국내 액셀러레이터는 초기단계이므로 관련 연구나 사회적인 합의가 매우 부족한 실정이다. 특히, 스타트업이 액셀러레이터의 프로그램을 통해서 얻고자 하는 부분에 대한 명확한 정보는 보다 정교한 액셀러레이팅 프로그램 설계를 가능하게 하여, 지원받는 초기 스타트업들의 발전에도 도움이 될 것이다. 이에 따라, 본 연구에서는 판단분석기법을 활용하여 액셀러레이터의 지원이 필요한 단계에 있는 스타트업이 액셀러레이터를 선택 할 때 어떤 부분을 고려하는지에 대해서 알아보았다. 본 연구를 통해 스타트업이 액셀러레이터 선택 시 의사결정에 대한 합의와 액셀러레이터의 발전 방안을 제시하고자 하였다. 실증 분석 결과 스타트업이 액셀러레이터를 선택 시 의사결정요인에 가장 큰 영향을 미치는 요인은 후속 투자유치로 나타났다. 이는 초기 단계의 스타트업이 성장을 위해 가장 중시하는 요인을 투자라고 생각하며, 이를 액셀러레이터에 원한다는 것으로 해설할 수 있다. 이러한 연구결과가 국내 스타트업의 액셀러레이터 정책 수립과 관련 산업 활성화를 위한 방향 설정에 도움을 줄 수 있을 것으로 기대하며 본 연구와 함께 액셀러레이터와 관련한 후속 연구가 지속되길 기대한다.

As the construction industry develops, environmental pollution gets increasingly serious, giving damage including the increase of incidence of respiratory diseases and skin diseases among children with weakened immune systems, rather than adults. In daycare centers, infants and children spending much of their time, have high frequency of contact with the interior floor finish material. However, the majority of the child care centers don not use eco-friendly flooring but ordinary monorium flooring, because the initial investment cost of the eco-friendly flooring is higher than ordinary monorium flooring. Therefore, in this study, life cycle costs including the initial investment cost of the eco-friendly flooring and ordinary monorium flooring were calculated, demonstrating that the eco-friendly flooring is more economical than ordinary monorium flooring in terms of life-cycle cost. In addition, the analysis of the environmental performance also showed the excellence of the eco-friendly floor finishes. It is expected that the use of the eco-friendly floor finishes will increase due to their excellence in the aspect of life cycle cost and eco-friendly performance, through this study.

In this study, air conditioning systems include ground source heat pump (GSHP), are evaluated for economic feasibility. The building is modeled an air conditioned for 280kW scale. This analysis is compared with the energy tariff programs of Korea and USA. The objectives of this paper are to evaluate the cost-effectiveness of the GSHP and combined system using Life-Cycle Cost (LCC) analysis, and to carry out the sensitivity analysis of key parameters. The paper considered the cases including the base case of air source heat pump and the other two alternates for comparisons. The combined system is not only a cost-effective way to the low energy consumption but also a way to avoid a high initial investment. The variations of initial investment and energy rates give a significant effect on the total LCC and payback period.

The amount of water resources that can be used tend to be decreased gradually. In contrast, the rapidly increasing water consumption is a problem that need to be addressed. Renovation and equipment replacement to improve energy efficiency and to reduce expenditure for building usage is required. But the excessive initial investment cost and the prolonged of pay back period may be uneconomical choice. Water usage for cleaning the toilet bowl accounts for 27%of the total water usage. Water-saving valve that can select the amount of water for cleaning toilet bowl can be reduced expenditure. After installing water-saving valve, analysed the economic effects. Water-saving valves compared with flush valves, and researched the amount of water usage. Then analyzed for the economic effects. Water-saving valve was used 5.6 ${\ell}$/time for cleaning toilet bowl. In contrast, flush valve was consumed 8.4 ${\ell}$/time. Water-saving valve's water-saving rate was 33.3%. The initial payback period for Water-saving valve was 459.5 days. By a small investment in water saving valve, the economic benefits can be obtained.

Plural governance system in which firms use vertical integration and market governance simultaneously are widely used across various marketing context. Typical examples of plural governance include franchise systems, in which firms own and operate some unit themselves while licensing the operation of some of their units to franchisees. Despite many scholars have attempted to explore the structure of plural governance over decades, there are few insights into its determinants. In this study, we examine the relationship between the proportion of outlets franchised and several franchisor's characteristics based on the perspectives of transaction cost analysis, resource scarcy theory and agency theory. Using franchisor data in Korean Franchise Disclosure Document over the 2006-2009 period, we test the effect of franchisor size, system growth rate, franchise fee, initial investment, and risk sharing on the proportion of outlets franchised. Except for the effect of system growth rate, the results of a series of multiple regression analysis supported the negative effects of franchisor size, franchise fee, initial investment and risk sharing on the proportion of outlets franchised.

This study quantitatively analyzes the work performance of the structural safety diagnosis team that diagnoses pipe racks. To this end, a method for evaluating the performance of the structural safety diagnosis team using the queuing model was proposed. For verification, the case of applying the existing method and the method of introducing a 3D laser scanner for one site was used. The period, number of people, and initial investment cost of each project were collected through interviews with case project experts. As a result of analyzing the performance of the structural safety diagnosis team using the queuing model, it was possible to confirm the probability of delay in the work of each project and the amount of delayed work. Through this, the cost (standby cost) when the project was delayed was analyzed. Finally, economic analysis was conducted in consideration of the waiting cost, labor cost, and initial investment cost. The results of this study can be used to decide whether to introduce 3D laser scanners.

Purpose - This paper examines the impact of labor market regulations on FDI and the production of foreign firms. Design/methodology - We use an index of employment protection along with data on the FDI and production of foreign affiliates that are provided by the OECD. Findings - The empirical results show that strict employment protection discourages both the production and initial entry of foreign firms, with its impact on production being larger than that on the initial entry decision. The result is robust to various specifications in which instrumental variable estimations are used by applying a unionization rate and a severance pay for redundancy dismissal as instruments, respectively. Therefore, policymakers should not limit their focus to tax incentives, cash grants, and relaxation of market regulations, but they should also extend their attention to labor market deregulation and decreasing non-wage cost to attract more foreign firms into their countries. Originality/value - This paper attempts to answer the question on the impact of employment protection rules on the foreign firm's decisions regarding production as well as initial entry.

This paper deals with the annulment of the ICSID(International Centre for Settlement of Investment Disputes) arbitral award. The annulment of the ICSID is characterized by the fact that it can be made possible through the special committee of ICSID only. The annulment of the ICSID was constructed on the premise that it is not an appeal procedure. However in the initial period, it was strongly criticized as it allowed new trials or duplicated many of the functions of an appeal and it broke down the boundary between the two systems. Although the trend seemed to be corrected through its 2nd and 3rd generations, it was still criticized for functioning as a new trial. It is approaching its 4th generation. On the other hand, with the activation of investment agreement arbitration based on ICSID and FTA, a certain degree of consistency is required for the ICSID arbitralaward. Also, with the emphasis on the public features of the arbitration for the investment agreement, the necessity of an appeal system is presented. The ICSID Secretariat published the "Opinion on the Appeal Procedure" in 2004 but as the system was criticized as too early due to the cost allocation problem and others, its adoption of an appeal procedure has been delayed. This paper focuses on how the currently incomplete ICSID arbitration judgment annulment system shall be used. Although it is still hardto expect the quality and consistent arbitral award annulment in the ICSID, this paper suggests that the "annulment without the actual new trial" using the restricted authority of a special commission in a creative way shall be pursued rather than just the actual new trial with or without annulment, thus going back to the original concept of the ICSID arbitral award annulment.
