A survey questionnaire that addressed the issues to manure compost producers and users was prepared. The questionnaire addressed three main topics as follows: 1) types of manure treatment and composting facilities are being operated, 2) quantity of manure compost produced and used, 3) problems experienced in producing and using manure compost. A total of 30 manure compost producers and 10 manure compost users were interviewed. Solid manure are applied to composting. Slurry and wastewater are simplified aeration method to produce liquid fertilizer. The open elongated type manure composting are generally used on manure compost centers jointly used by several farms. The amount of annually manure compost production was most common in the range of $5{\sim}10$ thousand tons per manure compost center. The manure compost utilization and cucumber yield were mostly $6{\sim}15$ tons and $20{\sim}27$ tons per 10a of cucumber farmland, respectively. Environmentally friendly use both of manure compost and chemical fertilizer are recommended for natural recycling agriculture.

The purpose of this study is to analyse the impact of macroeconomic and non-macroeconomic forces on the management performance of the air transport firms and offer the useful information to the managers. To conduct the regression analysis, eight macroeconomic and non-macroeconomic variables were selected individually as an independent variable. Macroeconomic variables were the return of corporate bond, West Texas Intermediate, the unemployment rate, the money supply, the trade balance, the won to USD exchange rate, the consumer price index and the index of industrial production. And non-macroeconomic variables were Taiwan earthquake, the Asian economic crisis, the 911 terrorist attacks in the US, the Iraq war, Beijing Olympic, the outbreak of a swine flu epidemic, the 1st presidential election and the 2nd presidential election. And ROA was selected as a dependent variable. As the result of analysis, it was found that the changing rates of won to USD exchange rate and consumer price index affected the changing rate of ROA significantly. And also as the result of analysing the impact of two significant macroeconomic variables and eight non-macroeconomic variables on the changing rate of ROA, it was found that the Asian economic crisis and the outbreak of a swine flu epidemic had a negative impact on it. Therefore managers should take note of a change in macroeconomic and non-macroeconomic variables carefully to improve the management performance.

Objectives : This study aimed to analyze the trend of financial balance of Korean medicine clinics during 20 years, and to provide basic information for adjusting the fee schedule of Korean medicine procedures in national health insurance(NHI). Methods : We collected 6 financial analysis reports for Korean medicine clinics from the Association of Korean Oriental Medicine(AKOM). The data on incomes, costs and EBIT(earning before interests and taxes) of subject clinics were abstracted, and their long-term trends were evaluated. Results : The proportion of insurance income in total income increased from 23% to 56% during 20 years. Among 5 treatment groups, 'non-insurance medication' took up 65~67% of total incomes in 1997, but its proportion decreased to 42.4% in 2007. 'medical procedure, physical therapy and others' increased from 12.4% in 1987 to 29.2% in 2007. The labor cost was major part of total cost and its proportion maintained from 52% to 54%. Cost of 'non-insurance medication' was on the decline from 41% in 1996 to 31.6% in 2007. EBIT were -17.4 million won in 1996, and 18.4 million won in 2007. Conclusions : Financial balance of Korean medicine clinics improved until early 2000, but it became worse in 2007. Though deficits from NHI procedures has been covered up by profit from 'non-insurance medication', health insurance became a major source of income during last two decades.

최근의 정보통신은 하루가 다르게 기술혁신에 의한 변화를 맞이하고 있는 가운데, 기술이 시장을 주도하여 신기술이 시장구조를 변화시킴은 물론 정보통신 사업구조를 크게 개편시키고 있다. 정보통신망기술은 다양한 멀티미디어 정보를 대량, 고속으로 전송·교환할 수 있는 방향으로 발전되고 있으며, 단말기는 유·무선전화서비스를 비롯하여 영상정보까지 다양하게 송수신할 수 있는 보다 작고 간편한 멀티미디어 일체형으로 발전하고 있다. 서비스분야에서는 디지털화, 고속화, 광역화에 따라 문자, 음성, 영상 등이 통합된 멀티미디어서비스가 보급되고 있으며, 특히 '7년부터 상용화된 인터넷을 통한 전화와 방송서비스는 정보통신분야에 새로운 사업영역으로 등장하고 있다. 이로인해 기존의 통신사업 질서인 “유선통신 대 무선통신”, “기본통신 대 고도통신”, “통신 대 방송”의 개념은 무너져 버리고, 기술과 시장이 상호 융항되어 새로운 통신사업 구도를 형성시키고 있다. 이의 대표적인 사례는 인터넷분야이며, 기존의 전화사업은 물론 CATV등 방송사업에까지 시장잠식과 구도변화라는 형태로 커다란 영향 미치고 있다. 국내 정보통신 사업정책도 이러한 세계적인 추세에 따라 이미 지난해 별정통신 사업자의 신설 등 정책과 제도를 바꾸었으나, 기술혁신 속도보다 늦게 반응하여 사업초기에 혼란을 주고 있는 실정이다. 최근 기술에 의한 시장구조 변화에 대응하기 위하여 정부는 기존 국가 초고속망구축사업도 대폭 수정하여, 즉 모든 가입자선로를 광케이블로 연결하는 당초의 계획을 ADSL 등 기존 전화선의 활용과 WLL기술을 선택적으로 적용시키고 있다. 통신사업자들도 유선위주의 전송망과 가입자망을 LMDS, WLL 등의 무선통신망으로 구축하려는 현상이 나타나고 있으며, 정보통신 정책도 과거의 유·무선통신을 별개로 취급하던 정책에서 선회하여 겸업 또는 연계를 권장하는 방향으로 전환되고 있다. 이와같이 정보통신분야의 기술혁신과 새로운 서비스의 도입은 기존 서비스시장의 시장잠식은 물론 유·무선영역을 무너뜨리고, 고정사업자와 무선사업자간의 영역이 허물어지는 등 사업자구도를 크게 변화시키고 있다. 이러한 기술혁신의 영향으로 시장경쟁은 심화되어 단기적으로 기존 통신사업자의 경영수지가 악화되기도 하지만, 요금인하를 수반한 신기술서비스의 공급은 이용자 입장에서 저렴하고 양질의 정보통신서비스를 제공받을 수가 있으며, 장기적으로는 서비스이용 증가로 인해 전체적인 시장크기는 더욱 확대되어 통신사업자와 이용자 모두 효율성을 나타낼 수 있을 것으로 전망된다.

As the scarcity of natural resources has become apparent, the recycling industry has emerged as a promising one for its growth potential. Yet, the recycling industry still remains undeveloped and inefficient for various reasons. In this study, we focus on firms' recycling processes to understand the current status of recycling firms' value creation activities. With respect to the adopted recycling processes, we empirically investigate the differences in firm characteristics and firm performance. We use the data from Keco (Korea Environment Cooperation) which annually conducts a survey of recycling firms in Korea. We exclusively consider the whole group of plastic recycling industry in order to control for a possible bias in firm performance, stemming from the heterogeneity in processing and recycling of materials other than plastics. We review the descriptive statistics from the sample firms and conduct a series of hierarchical regression analyses. The results show that most of the firms in this industry adopt physical transformation processes with a low-level technology. These firms with physical transformation processes are smaller in size and produce entry level items which do not secure higher margins. The results indicate that the recycling industry largely comprises low value added firms which lack economies of scale and resources for R&D. For the stable growth of the industry, recycling firms must create sustainable values through implementation of technology-driven processes and improvement in product quality. In addition, the government should help build a reliable reverse logistic network, lower the entry barriers, and provide necessary funding for the SMEs in the recycling industry.

The purpose of this study is to analyze the factors affecting financial performance of community pharmacies after the implementation of the new drug policy in Korea: separation of drug prescription and dispensing (SPD). The online survey questionnaires were sent to the active pharmacists of the total 20,633 community pharmacies in Korea and 1,147 pharmacists responded to the survey (the response rate was 5.5%). The questionnaire asked simple financial data in order to compare their financial performances before and after the policy. With the SPSS package (version 12.0), two levels of data analysis were used: 1) descriptive statistics to see the financial status of the pharmacies; and 2) multiple regression analysis to find the factors. {or A multiple regression method was used for the data analysis.} The finding illustrated that the average net benefit of the pharmacies was 4,870 thousand won in August 2006, and the major factors affecting the net benefit were the location of pharmacy (geographical proximity to medical institutions), number of prescriptions, drug management services for patients, chain pharmacy membership. The findings of this study suggest that service improvement for patients, revitalization of non-prescription drug sales, professional management will contribute to promote community based pharmacy business.
