This study analyze the factors affecting the number of bidders in public contracts by collecting contract data such as purchase of goods, service and facility construction through KONEPS among various forms of public contracts. The reason why the number of bidders is important in public contracts is that it can be a minimum criterion for judging whether to enter into a rational contract through fair competition and is closely related to the budget reduction of the ordering organization or the profitability of the bidders. The purpose of this study is to analyze the factors that determine the participation of bidders in public contracts and to present the problems and policy implications of bidders' participation in public contracts. This research distinguishes the existing sampling based research by analyzing and analyzing many contracts such as purchasing, service and facility construction of 4.35 million items in which 50,000 public institutions have been placed as national markets and 300,000 individual companies and corporations participated. As a research model, the number of announcement days, budget amount, contract method and winning bid is used as independent variables and the number of bidders is used as a dependent variable. Big data and multidimensional analysis techniques are used for survey analysis. The conclusions are as follows: First, the larger the budget amount of public works projects, the smaller the number of participants. Second, in the contract method, restricted competition has more participants than general competition. Third, the duration of bidding notice did not significantly affect the number of bidders. Fourth, in the winning bid method, the qualification examination bidding system has more bidders than the lowest bidding system.

본 연구는 우리나라 대학의 창업교육센터(Entrepreneurship Education Center)에 대한 조사를 수행하여 선행 조사DB와 비교 분석하였다. 창업교육센터 실태조사를 바탕으로 대학별 정량적 정성적 지표를 측정하여 상위그룹과 하위그룹의 구분하고 두 집단의 차이점과 성공운영 요인을 분석하였다. 창업교육센터의 일반 현황과 특성, 교직원(교수자수, 교원창업자수), 교과목(과목, 수강인 원수), 학내외 프로그램(창업동아리, 창업경진대회, 창업캠프), 재정운영(예산, 전담인력) 등의 계량 지표는 대학정보공시(대학 알리미)와 중앙일보 대학평가 DB를 기초하여 조사하였다. 그리고 운영상의 문제점, 센터의 성과측정 항목 등 정성지표는 창업교육센터장을 대상으로 설문 조사하였다. 또한, 국내 창업교육센터의 표본특성을 살펴본 후 상위그룹과 하위그룹의 차이를 규명하여 상위그룹이 보유하고 있는 인적 물적 역량과 프로그램의 분석하여 창업교육센터의 활성화 방안을 제시하였다. 본 연구는 교육부의 "산학협력 선도대학(LINC) 육성사업 (2012년~2106년)"에서 창업교육을 총괄 지원하기 위해 2012년 대학에 설치된 전담조직인 61개 창업교육센터의 성과를 분석하고 대학평가에서 상위 순위에 있는 대학 그룹들의 차이점을 도출하는데 의미가 있다. 또한 2017년에 새롭게 지정된 LINC+ 사업 ('17년~) 창업교육 분야의 정책적 시사점을 제시한다. 본 연구의 목적을 달성하기 위해 문헌연구와 창업교육센터 운영에 대한 구조적 설문지를 개발하여 실태를 분석하였다. 이 결과는 창업교육센터의 효율적 운영을 위해 대학교직원 연구자 공무원 학생 및 창업교육센터를 포함한 창업지원 기관의 이해 관계자에게 향후의 발전을 위한 자료로써 의미가 있을 것이다.

ECR(Electron Cyclotron Resonance)은 전자기장에 의한 회전주파수와 전원으로 가해지는 마이크로웨이브(microwave)의 주파수가 일치할 때 발생하는 공진(resonance)현상이다. ECR에 의해 형성된 고밀도, 고에너지의 플라즈마가 상온하에서도 표면에너지가 낮은 고분자수지상에 접착력과 내구성 및 성능이 우수한 금속박막을 형성시킬 수 있는 특징을 지니고 있다. [1] 이러한 고분자수지 표면에 제조되는 금속박막소재는 반도체산업을 비롯하여, 박막전지, 전자파 차폐 등의 다양한 용도로 개발되고 있다. 그러나, 고분자수지와 금속박막계면간의 접착성의 저하로 후처리 공정에서 외부의 응력을 받게되면 막이 쉽게 탈리되는 문제점이 대두되었고, 이에 대한 개선이 요구되고 있다. 따라서, 본 연구에서는 공업적으로 많이 사용되는 표면 전처리방법을 통하여 구리 박막의 접착력을 향상시키고자 하였다. 상온화학증착 방법에 의해 고분자수지표면에 구리금속박막을 제조하고 여러 가지 표준방법을 사용하여 고분자수지와 구리박막간의 접착특성을 조사하였다.

본 연구는 종부형태가 이유한 암돼지의 번식성적에 미치는 영향을 조사하기 위하여 이유후 4-6 일경에 자연발정이 발현되어 수정적기라고 판단되는 암돼지에 12시간 간격으로 각각 자연종부 2회, 인공수정 2회 및 혼합교배(자연종부 l회＋인공수정 1회)의 형태로 나누어 종부하고 분만율과 산자수를 조사하였다. 분만율은 자연종부 78.5%, 인공수정 76.3% 및 혼합교배 76.0%로 나타나 종부형태간에 유의적인 차이가 없었으나 총산자수는 자연교배 9.89 두와 인공수정 10.04 두의 단독 종부 형태 보다 혼합종부형태가 10.26두로 높게 나타났다(P<0.01).

Silk, polyester, cotton, and wool fabrics were embroidered with varying stitch length of 3mm, 5mm, and 10mm to examine the difference in fabric shrinkage in terms of sewing direction, fabric thickness, cover factor, stitch length, and fiber type. Warp, filling, and bias direction of sewing resulted in no difference in fabric shrinkage. Within the samples with same stitch length, there was less fabric shrinkage in fabrics with higher fabric thickness or higher cover factor. There was larger shrinkage when sewn with longer stitch length. Comparing fabrics with different fiber types but similar fabric thickness, silk and polyester fabrics showed the smallest fabric shrinkage and wool fabrics showed the largest shrinkage. It is shown that similar fabric shrinkage between silk and polyester is due to the similarity in cover factor.

The purpose of this study is to analyze the industrial accidents data with survival model. EDA approach is used to explore the relationship between two variables and among three variables for the past 10 years of industrial accidents data. Survival models are also tried. Survival curve drops more rapidly for the business with fewer employees as time goes by. Industrial accidents occur more often as the total number of industrial accidents gets larger and as the number of employees gets smaller. Agriculture, fishing and forestry have a higher level of industrial accidents than construction while service industry and 'transportation·storage and telecommunication' have a fewer number of industrial accidents than construction. Korea Safety and Health Agency's and Ministry of Employment and Labor's involvement were not effective but Civilian's was. Recurrent event data analysis reveals all most the same result as for non-recurrent data analysis.

As the complexity of society increases, the demand for the forest-based recreational site is also increased. This, in turn. makes congestion an ubiquitous type of externality in forest-based recreational site. Efficient resource allocation requires this congestion effect to be accounted and considered in the decision making process. In this content, this study was conducted to suggest a process which can be used to measure the congestion and determine the optimal number of users. Willigness to pay(WTP) function obtained from Book Han San National Park users suggested that every 20.000 users increased decrease the satisfaction of users obtained from the site visit be 27.3%. For the purpose of demonstration this WTP function is applied tit determine the optimal number of users which is estimated as about 73,000 persons per day.

Pricing for e-journals has become more complex than before-certainly much more complex than print pricing has ever been. E-journals charge either a fiat fee based on print, user, library size, usage, and combination. A survey of publisher's pricing structure found that print based model is popular followed by user based model. The current pricing situation is far from equitable and can be improved if publishers can be coerced to change their pricing practices. This study focus on a number of possible pricing models that may supplement and/or possibly replace the current print based model. With the possibility that its pricing will eventually be based strictly according to usage, may lead to the most equitable pricing model as well as the most efficient use of society's resources. Libraries can alleviate the pricing problem by encouraging library organizations and university consortia to exploit their potential monopoly power into a bilateral monopoly situation.

The accident rate is obtained by dividing the number of accidents by the number of regular workers. In the case off construction work, however, the accident rates are not accurately figured out, because they use the approximate number of regular workers, which is estimated based on the amount of construction work and the labor ratio. In addition, the current accident rate estimation method does not reflect the characteristics of construction types, such as building, civil, plant, etc. This study is conducted with the aim of presenting a supplementary method of accident rate assessment that incorporates the characteristics of type of construction. For the purpose of this, correlation and regression analysis are executed to verify the relationships between number of accidents and the amount of construction contract, and several equations are derived which shows the relationship between the number of accidents by accident types and amount of constract by construction types. The result shows that the non-residential work amount and the number of accidents showed a proportional relationship, while the civil work amount and the number of accidents showed an inversely proportional relationship. The results of this research are expected to calibrate the construction accident rates and to be used as an auxiliary indicator to determine the trend of annual accident rates by comparing the values with usual years.
