투자결정요인과 환경요인이 한국중소기업의 對중국직접투자 경영성과에 미치는 영향에 관한 연구

송재훈 한국중소기업학회 2002 中小企業硏究 Vol.24 No.2

본 연구는 중국에 진출한 한국의 중소기업을 대상으로 하여 투자결정요인과 중국의 경영환경 요인이 그간의 경영성과에 어느 정도의 영향을 주었는가 하는 분석과 이를 통해 새로운 투자전략을 수립해 보이는 데 그 목적이 있다. 따라서 연구모형은 투자결정요인과 환경요인을 독립변수로 하였으며 경영성과를 종속변수로 구분하였다. 경영성과의 경우도 단기적인 측면(기대이익 실현)과 장기적 측면(사업의 장기 지속성)으로 세분화하였다. 실증연구의 결과 단기적인 관점에서 보면 투자결정 요인중 투자동기에서는 시장기반의 확보가, 투자형태에서는 의사결정 참여도와 거리의 원근이 유의적으로 나타나 경영성과에 영향을 주었고 환경요인과 경영성과와의 관계를 살펴보면 중국근로자의 생산성이 성과에 높은 영향을 미치는 것으로 나타났다. 장기적인 관점에서 파트너의 협상력 이용, 용이한 시장진출(이상 투자동기요인) 그리고 정보의 부적절성(환경요인) 등이 부정적인 효과를, 중국근로자의 생산성이 긍정적인 효과를 나타냈다. The purpose of this study is to finding out business performance investing in China in case of Korean medium & small enterprises. Empirical test was conducted on evaluating the interrelation among Business Performance Factors, Investment Decision-Making Factors, Environmental factors. Major empirical results are summarized as follows: First, guarantee of market base was positively significant with short-term performance. Second, invest information and area were significant with investment decision-making factors. Third, Chinese labor's productivity was very influential to the short-term performance. Fourth, in the long term performance, using parter's negotiation power and validity of information was negatively significant, but Chinese labor's productivity was positively effective with performance.

It is so difficult to know about the course of non-point source that only few people studying. This is the reason why we did not get good result in water-treatment frequently. Point and non-point source study must be balanced. This report have this intention. Summer is rain season in Korea so we have many problem in water quality. Bad quality originated from agricultural field, non-point source, that flow nutrients, agricultural chemicals, weed chemicals and etc. In this report provide the basic data of non-point source study on river of Haenam Area. Three point that we research is near Bok-pyoung, Kil-ho and Eo-seong bridge at 1999. 7. 5 ∼ 7. 12. Resulted: BOD, COD, SS, T-N, NH₃-N, NO₃-N, T-P, PO₄-P, Alkalinity decrease afterraining, dilution, much amount of water quantity made it. Agricultural section that major non-point source effluent high waste concentration at first stage, but dilution made lower at last. so it is needed that non-point source water storage for improve first stage wastewater at the lower part of a river. And continuous study about non-point source outbreak reason by waste effluent quantity data that made water quality and quantity research after division of the land useness near the river is needed, too.

목적 : 소음 특수건강진단시 문진표의 유용성을 알기 위하여 실시되었다. 방법 : 자료로는 전국을 5대 권역으로 나눈 후 연구에 협조적인 산업보건기관을 대상으로 하여, 소음성 난청이 발생한 사업장과 그 부서에 대하여 정상인 근로자의 검진기록과 작업환경측정 기록 및 문진표를 수집하여 분석하였다. 결 과 : 각각의 문진 항목과 청력이상 여부에 대한 분석결과, 귀에서 소리가 난다고 하는 항목과 최근 작은 소리가 잘 안들린다고 하는 만성 특이적 항목만 청력이상 여부와 관계가 있었고, 급성 항목들은 청력 이상 여부와 통계적 연관성이 없었다. 또한 7개의 설문 항목과 연령 및 근무경력만을 이용하여 청력이상을 판정한다고 하였을 때, 실제 건강진단 결과와 비교하게 되면 민감도, 59 %, 특이도, 88 %로 계산 되었으며, 평균 23 %정도가 잘못 분류되었다. 결 론 : 만성적이고 특이적인 항목을 위주로 한 단순하고도 판별력있는 항목의 개발이 필요하며, 이러한 항목들을 전산화하였을 때, 효과적인 소음성 난청의 선별검사 체계를 구축할 수 있을 것이다. Objectives : This study was performed to investigate the effectiveness of the questionnaire. Methods : Workers'health examination records, work environment record, and questionnaires of selected industries as samples were analysed using logistic regression analysis and discrimination analysis Results'Cases of bearing impairment (Dl+C) as dependent variables, and age, work duration and level of environmental noise as independent variables were selected for multiple unconditional logistic regression analysis. Odds ratio was 4.04 in hearing difficulty, 2.78 in tlnnitus and 1.08 in age. In the second analysis Noise induced hearing loss is selected as dependent variable. The OR in hearing difficulty was 3.67(95 % C.1. : 1.61 8.61), and was 1.09(95 % C.1. : 1.05-1.14) in age. Conditionnal multlple logistic regression analysis was performed. In hearing impairment as dependent variable, the OR of age was 1.02(95 % C.1. : 1.00-1.04) and other variables were not significant. However, NIHL as dependent, the OR of hearing difficulty was 4.57(95 % C.1. : 1.43-14.67). According to multiple logistic regression adopting each items of questionnaire as dependent variable, the only item of hearing difficulty showed significant difference with hearing ability. The discrimination analysis was performed with the class variable of hearing impairment, and discrimination variables of age, work duration, and environment noise level. The sensitivity of 59 %, and specificity of 88 %, and average error count of 23 % were obtained. When the numbers of items answered in questionnaire were assumed as the parameter of judgement for noise induced hearing loss (NIHL), the highest sensitivity and specificity were 33.5% and 49.0% in cases of more than two items answered. Conclusions : The development of items that is simple and discriminative mainly consisted of chronic and specific diseases related items is needed. Computerization for newly developed items might be needed to establish effective surveillance system for NIHL in the future.

투자결정요인과 기업특성요인이 한국기업의 對중국 투자전략 수립에 미치는 영향에 관한 연구

송재훈 대한경영학회 2003 大韓經營學會誌 Vol.16 No.6

This article, using the J.H.Dunning's Eclectic Theory(OLⅠ model), identifies the decision-making factors and firm's characteristic factors that explain Korean firms' FDI activities in China from 1988 to 2002. Section" Ⅰ" offers data on Korean firms' FDI activities in China for each year between to 1988 and 2002 and in aggregate for that period: the number of FDI, their dollar value, preferred geographical location, targeted industries, and degree of equity of ownership. Section" Ⅱ", using the J.H.Dunning's model, identifies the characteristics of Korean firms investing in China, their motivation for doing so, and the decision-making factors and firm's characteristic factors guiding their FDI decisions. The primary motivations for FDI by Korean firms in China are the availability of lower labor cost and the attraction of a rapidly growing market. This research also found that the FDI pattern is increasingly changing from investment in labor-intencive, low technology industry to high technology, capital-intencive industries. As per this study, decision-making factors of importance are ownership-specific and location-specific advantages. Internalization-incentive advantages are not applicable to Korean firms' investment decisions.

During a three-year period, 600 patients were admitted to the Asan Medical Center because of biliary tract diseases. Both aerobic and anaerobic cultures were performed in 313 patients with cholangitis (bile : 253, blood : 113, both : 53). Of these patients, 189 were positive(bile 159. blood 68. both 38). The most common organisms were E. coli, K pneumoniae, and P. aeruginosa in both bile(respectively, 49.7%, 20.8%, 51.5%) and blood cultures(respectively, 45.6%, 26.5%, 22.1%). Antibiotic therapy did not sterilize bile, but selectively increased the proportions of P. aeruginosa. There was no significant difference in biliary bacteriology according to the history of biliary surgery, or the presence of percutaneous biliary drainage or underlying disease. More than 95% of gram-negative organisms isolated was highly susceptible to imipenem and amikacin. P. aeruginosa was resistant to ceftazidime in 63.3% which might be associated with overuse of the drug during the study period. Further studies will be necessary in patients with cholangitis to determine whether newer antibiotics replace previous combination therapy.

A successful therapy of community-acquired pneumonia requires appropriate empirical antimicrobial therapy. Etiology and antimicrobial susceptibility of major pathogens of pneumonia can differ by country. Therefore, an ideal treatment guideline of community-acquired pneumonia should be based on the studies performed in each country. We developed a treatment guideline for community-acquired pneumonia in immunocompetent adults in Korea. This guideline was developed by the joint committee of the Korean Society for Chemotherapy, the Korean Society of Infectious Diseases, and the Korean Academy of Tuberculosis and Respiratory diseases.
