Results were obtained through the study as follows: 1. There are 14 junior health colleges in Korea and 3,106(79.9%) licensed dental technicians out of 3,885 graduated from health colleges and rest of them obtained their licenses through practical training in dental clinics. 2. 8,030 applicants have applied to the national examination which was carried out for 22 times during 1965 - 1985. The passing rate in the examination for 22 times showed 48.3% in average. 3. The dental technicians are working mostly in 404 dental laboratories and 2,522 dental clinics and hospitals through out the country. However, most technicians are dominantly working in large citis, because 255 (63.1%) dental laboratories and 1,537 (60.9%) dental clinics and hospitals are mainly located in Seoul and Busan. 4. Regarding distribution of the dental technician, 1,126(52.1%) technicians have been employed in the dental institutions, however, 530 (24.5%) could not have a job and the rest of them (504 technicians: 23.3%) were in leave absence from military service, travelling abroad and unknown reasons. 5. Through reference review, it was found that there were 95,886 dental technician (9/ 100,000 population) in the world during 1973$\sim$1977. However, 91,553 dental technicians lived in the developed countries (14/100,000 population)) also ratio between the dentist and the dental technician in the world showde 1:0.38. In such coentries where per capita income showed $100 in average, the distribution of the dental technician showed 0.272 per 100,000 population. 6. In an estimation of demand and supply for the dental technicians by the year from 1985 through 1996 in Korea, the supply is estimated by the capacity of educational institutions as over-production even through such estimation based on the future incresing of GNP and ratio between the dentist and the dental technicianas and also ratio between the dental technician and general population. At present such ratio shows less compared with the developed contries, however, it is estimated as over-supply in 1994.

This paper analyzes the consistency and the discrepancy between system and practices of the old age pension(Nyunronyungeum) in North Korea. The literature review is conducted to analyze the system. Specifically, the North Korean law and North Korean dictionaries were carefully examined. The interviews with 25 North Korean refugees were conducted to grasp the exact state of the old age pension in North Korea. Major findings are as follows: the consistency between system and practices of the old age pension in North Korea is identified only certain portions of that. Beneficiaries(blue-collar workers, white-collar workers, farmers, soldiers, and employees in foreign-invested enterprises), contribution periods, earning-related schemes, the totalization of periods of coverage(workplace transitions), the absence of double benefits and early retirement pension, and the delivery system around Civic Service offices(Dong offices) are confirmed by complete consistency. Preservation age, variations in the implementation of the pension system by region, and premium of the old age pension are confirmed by partial consistency. The length of service, the labor regulation, lump-sum payment, and double dipping are confirmed by discrepancies. It's important that this study brings about a better understanding the old age pension in North Korea through various original texts of North Korea and interviews with refugees. The results of this study are expected to contribute to the policy production for the age income security system after the unification and to the spread of unification perspectives.

The purpose of this study was to compare the taxation equity of non-residential collective real estate based on its standard market prices set by National Tax Service and those for taxation set by the Ministry of Government Administration and Home Affairs with that of the apartment houses in Seoul, South Korea. The study findings were as follows. First, the analysis results of the standard market price rates of non-residential collective real estate pointed to a huge gap in the assessment rate (AR) of the taxation standards among the Gu offices. Second, there was a big coefficient of dispersion (COD) in the standard market prices of non-residential collective real estate, which confirmed the presence of horizontal inequity. Finally, there was regressive vertical inequity, which leads to the undervaluation of high-value assets, in the standard market prices of non-residential collective real estate. The evaluation of the standard market prices of non-residential collective real state should thus reflect the market prices and the addition and assessment of the land and buildings to achieve taxation equity. Based on these findings, it is hoped that this study will make a significant contribution to the improvement of the official announcement system for non-residential real estate based on real transactions during the shift to such system.

Since the late 20th century, there has been much effort to improve the market value of media contents which are commercialized in a digital format, by fusing digital data of video, audio, numerals, characters with IT technology together. Then by what criteria and methodologies could the market value for the drama "Sons of the Sun" or the animated film 'Frozen', often referred to in the meida, be estimated? In the circumstances there has been little or no research on the valuation framework of media contents and the status of their valuation system development to date, we propose a practical valuation models for various purposes such as contents trading, review of investment adequacy, etc., by formalizing and presenting a contents valuation framework for the four types of media of movies, online games, and broadcasting commercials, and animations. Therefore, we develope computational methods of cash flows which includes production cost by media content types, provide reference databases associated with key variables of valuation (economic life cycle, discount rates, contents contribution and royalty rates), and finally propose the valuation framework of media contents based on both income approach and relief-from-royalty method which has been applied to valuation of intangible assets so far.

This study aims to suggest effective management performances of nonprofit arts organizations among competitive environment. To examine the factors which affect the performance of nonprofit performing arts organizations such as external environment, cultural capital, orchestra characters and government grants, this study analyzed the data of 990 tax forms of the US Internal Revenue Service(IRS) of the top 73 symphony orchestras and government sources in USA. Independent variables are measured as sponsorship amount which is the biggest part of orchestras' income, and ticket sales which is profit of inherent business purpose. As a result, the performance of the orchestra is affected positively by the income and influenced by the orchestras' characteristics including age, size, and conductor. Also government grants to the orchestras are essential for organizations to sustain their business. But, there are two different sides on these effects that small to medium groups are influenced by crowding in effect and bigger groups are more likely conducted by business overview. Lastly, cultural capital is no significant relationships to orchestras' management performances. This scope of the study is limited to American symphony orchestras; however, this study is significant in that empirical analysis on nonprofit performing arts organizations from an economic view point and contribute on other nonprofit arts organizations to develop their strategic plan for sustainable business.
