산업단지는 국가경제성장과 국토균형발전의 정책수단으로서 지역 및 국가발전에 많은 기여를 해왔지만, 조성 후 30년 이상된 노후산업단지 비율이 높아지면서 산업단지의 혁신이 요구되고 있는 실정이다. 이에 본 연구는 전국의 1,220개 산업단지 중, 단지면적이 30만㎡ 이상인 157개 국가·일반산업단지의 생산성과에 영향을 주는 내외부의 영향요인을 탐색하고, 산업단지 생산액에 미치는 영향도를 분석하였다. 산업단지 생산성과는 산업단지 자체의 속성요인 뿐만 아니라 산업단지 위치에 따른 지역요인 및 산업단지 지원정책과, 상위수준 요인인 산업별 경기변동 요인에 의해 포섭되는 계층적 구조의 데이터 특성을 감안하여 위계선형모형을 통해 분석한 결과는 다음과 같다. 첫째, 산업단지들의 생산성과는 각 산업단지의 내부속성(계획적, 물리적, 입지특성, 노후도)에 앞서 각 산업단지가 위치한 지역과 입주업종에 교차분류된(cross-classified) 형태로 내포되어 있다. 둘째, 생산성과에 긍정적인 영향을 미치는 요소로는 업종별 총 생산액, 산업단지별 산업시설용지 면적, 산업단지 소재지역의 인구수, 조성완료 후 경과년도가 있으며 공공시설 면적률이 커질수록 생산성과를 낮추는 것으로 분석됐다. 산업단지별 생산성과를 측정하기 위해서는 상위수준의 외적요인 통제하에 산업단지 자체의 내부속성 요인들의 영향력을 추정할 때 정확도를 더 높일 수 있다. Industrial complexes have contributed crucially to regional and national development as a policy tool for national economic growth and balanced national development, but as the ratio of old industrial complexes that have been built more than 30 years ago has increased, an innovation of industrial complexes is required. Therefore, this study is conducted with 157 national and general industrial complexes with an area of over 300,000㎡ out of 1,220 industrial complexes nationwide. The internal and external factors affecting the production performance of general industrial complexes were studied, and the degree of influence on the output value of each industrial complex was analyzed. The production performance of industrial complex is the data of a hierarchical structure that is covered not only by the attribute factors of the industrial complex itself, but also by regional factors and industrial complex support policies according to the location of the industrial complex, and economic fluctuations by industry, which is a higher-level factor to the production performance of industrial complex. The results of analysis through the hierarchical linear model considering the characteristics are as follows. First, the production performance of industrial complexes is implicit in the form of cross-classified in the region where each industrial complex is located and the main tenant business type of the industrial complex beside the internal properties of each industrial complex. Second, factors that have a positive effect on the production performance are the total production output by the industry, the area of the industrial facility site by the industrial complex, the number of population in the industrial complex, and the year after completion. When external factors are controlled in the model, it is possible to estimate the impact of internal factors on industrial site production performance more accurately.

본 연구에서는 치열한 경쟁에 처해있는 인터넷 쇼핑몰(Internet Shopping Mall:ISM) 산업에서 생존을 위하여 필수적인 차별화 구현을 통한 수익성 향상 방안을 탐색한다. ISM 관리의 실질적 차별화를 가능하게 하는 실행 수준에서의 관리 요소를 분석하는 본 연구는 이제까지 주로 개념적이고 기업 수준에서 수행된 B2C 차별화 전략 연구와 ISM 고객만족에 영향을 주는 선행요건을 파악하는 실증적 연구를 효과적으로 결합하여 다음과 같이 진행 되었다. 첫째, 고객의 구매 의사결정 프로세스의 각 단계 별 거래비용 이론 관점에서 고객가치를 정의하였다. 둘째, 포괄적 문헌연구를 통하여 ISM 고객만족에 영향을 주는 요소들을 파악하고 이들 중 관리요소의 차별화가 가능하며 차별화를 통하여 고객 가치에 영향을 줄 수 있는 15개의 관리요소를 도출하고 연구모델과 가설을 수립하였다. 마지막으로 실증분석을 통하여 구조적 모델을 검증하고 차별화에 대한 시사점을 제시하였다. 본 연구는 ISM 차별화에 대한 실증적 연구로는 초기 단계에 속하는 연구로 본 연구의 결과는 ISM 차별화를 위한 향후 연구와 실무적 응용에 유용한 시사점을 제시한다. In this study, we investigated how to achieve differentiation for the ISM (Internet Shopping Mall) to improve profitability, which is required for survival in the fiercely competitive ISM industry. We analyzed implementation level key managerial factors that could contribute to the differentiation of the ISM. The research model is constructed through integration of two distinctive research streams of e-commerce. The one is B2C differentiation strategy research, most of which are conceptual and conducted at a strategy level, and the other is empirical research analyzing the antecedents of customer satisfaction at the ISM. This study is organized as follows. First, we draw upon transaction cost theory to organize constructs representing customer value associated with the customer buying decision process. Next, after reviewing comprehensive managerial factors that could impact on customer value, we selected 15 managerial factors that could contribute to the differentiation of the ISM to deliver value to customers. Finally, the resulting structural model is validated through empirical analyses. The results provide insights for future studies on ISM differentiation.

Purpose : The purpose of this study is to evaluate the effectiveness of operative methods for diaphyseal fractures of both forearm bones in adults. Materials and Methods: Forty five cases with diaphyseal fractures of both forearm bones over 18 year old that are treated by operative methods from January 1994 to December 1998 were followed and analyzed. The most common age group was 3rd and 4th decade(each, 24.4%). Traffic accident was the most common cause of injuries(31.2%). Among both the radius and ulna, middle 1/3 was the most common level of fractures(60%, 57.8%). In operative methods, open redeuction and internal fixation with dynamic compression plate(D.C.P.) and screws were performed in 39 cases, closed reduction and internal fixation with Rush pin were performed in 5 cases, And another 1 case was performed with D.C.P. and Rush pin simultaneously. Results: According to simple X-ray and physical examinations, The average of bone union periods was l2.7 weeks in radius, 13.5 weeks in ulna. The range of bone union periods according to the level of fractures was from 12.4 weeks to 14.1 weeks. For the functional results assessed by Grace and Eversmann method, excellent was 48.9%, good was 35.6%, acceptable was 11.1% and unacceptable was 4.4%. Conclusion: The functional result was satisfactory in 84.5%. So the operative method of diaphyseal fractures of both forearm bones, if proper operative method had been selected and meticulous surgical technique had been performed, was considered as recommendable method.
