A protected dinucleotide, 5'-O-dimethoxytritylthymidylyl-(3'→5')-3'-O-acetyl-N??-benzoyldeoxyadenosine, was synthesized by 'Phosphodiester Method' and separated by solvent extraction/recrystalization. The amino group of the base, 3'-hydroxyl group of deoxyadenosine-5'-monophosphate, and 5'-hydroxyl group of thymidine were previously protected with benzoyl, acetyl, and di-p-methoxytrityl group respectively before the condensation between the nucleotide and the nucleoside was conducted. The condensation reaction was more efficiently conducted with triisopropyl benzenesulfonyl chloride(TPS) than with dicyclohexylcarbodiimide(DCC). The dinucleotide synthesized was purified utilizing solvent systems isopropyl ether/0.5M triethylamminium bicarbonate (TEAB), ethyl ether-ethyl acetate (5:5, v/v)/0.5M TEAB, and 0.5M TEAB/CH₂CL₂-CCl₄(4:6, v/v). This method was more efficient than the ordinary diethylaminoethyl (DEAE) cellulose column chromatography.

The flexure strength distribution was observed with ball-on-3 ball test after thermal shock in 25℃ distilled water. Commercial alumina specimen(AES-11) was used, and after thermal shock and flexure test crack distribution was observed by dye-penetration. Statistical method for failure probability and comparison of failure probability of ball-on-3 ball test with that of 3-point bending test were studied. The nearest crack distance from the center of the specimen and crack density were considered as the factors affecting ball-on-3 ball test strength, and the nearest crack distance from the center of the specimen had a stronger effect on the flexure strength than crack density.

스웨덴의 노동시장정책

The purpose of this research is to find significance in the Swedish Labour Market Policy [SLMP], for supporting development of Korea's one. Sweden's unemployment experience differs radically from what has happened in most other European countries. Unemployment in Sweden has fluctured between 1 and 3.5% since the early 1960s, and there is only a weak trend increase ; the cyclical peaks in 1960s involved lower unemployment than the peaks in the 1970s and the 1980s, and the same holds for the slumps. Despite Sweden's excellent unemployment record, there are reasons for concern about a clear trend increase in the duration of unemployment. In the late 1960s, the average duration of a completed spell of unemployment was seven weeks ; in the mid-1980s, the unemployment who have remained so was about twice as long. But recently the fraction of the labour force unemployed for a year or more has exeeded 10%, and this is very same by European standards. Sweden' government make an effort to surment this problem by labour market policy. Generally, Labour market policy entails influncing the allocation of economic activities in time and space to meet the supply of labour, or, more simply, getting people (through traing, information, mobility allowances, etc.) to jobs, and getting jobs to people. Labour market policy is not social welfare, a means of keeping the unemployed off the streets and out of trouble. The rationale is first of all economic. Full employment brings an increase in the output of goods and services by making otherwise idle human resources productive. High unemployment means less output and greater dependency, thus increased cost in form of income transfers. But the logic does not end there. Even if afforable, income transfers cannot replace employment for people able to work. Work is part of living a normal life, even-especially-for those otherwise handicapped. Thus human well-being is inseparable from the functioning of the labour market. Full employment is at the core of social-welfare policy, 'the practical means of breathing life into a widely shared equalitarian philosophy.' In conclude, a core of SLMP is Active Labour Market Policy[ALMP], which is a main component of Sweden's post-war strategy for full employment. The main contends of ALMP are composed of labour supply-oriented programms, labour demand-oriented programms, relief work projects, and cash subsidy for the unemployed, etc.. Besides SLMP includes unemployment insurance, which is made of unemployment-benefits payment programms and cash labour market assistance(unemployment assistance). And prior to this SLMP' anaysis, I have expounded the conceptions and types of Welfare State, the changeable process of Swedish social welfare system, and the crisis of Welfare State and Welfare State Sweden, etc.. Finally the ultimate object of this study is to aid in escaping from 'the crisis of Korea's economy'.

The purpose of this paper is to investigate the nature of Korean capital by analyzing the process of capital accumulation in Korea during the period of 1945-1961. This study will be a tool for recognition of Korean capitalism. According to this study, the prime moments which contribute to capital accumulation are Farmland reform, Government-vested properity disposal, Aids and Treasury loans and investments. The major findings of this study are as follow; (1) Farmland reform partly converted land capital into industrial capital, and it enabled farmers to possess farmland. (2) Government-vested property disposal created material basis which formed the bureaucratic and monopolistic capital through the disposal. (3) Aids(mainly from United States) played a decisive role in the process of capital accumulation. But they were one strategy for advanced state monopoly capital. In conclusion, they made Korean capital subordinated to advanced monopoly capital. (4) The Allocation of Treasury loans and investments for which government raise counterpart fund is the creation process of greatly monopolistic capital. Ultimately, capital-labor relation that is the capitalist university of the reproduction on an expanded scale carried through the process of capital accumulation in Korea during that time. Therefore, the nature that Korean capital is subordinated to an advanced monopolistic capital and is depended on political power is consistent with expansion of capitalist reproduction in relation to monopolistic capital.

The aim of this study is to examine the phase of economic policy under Social Market Economy in Germang. The analysed results are as follows. Social Market Economy is Germany's economic system which was theorized by A. Mu¨ller-Armack, as is generally known, and is based on the order-liberalism which was formed by W. Eucken, a representative neo-liberalist in Germany. There fore the Germany's economic policy is a making process and measure of economic order to preserve and develop Social Market Economy. We expect that this study gives the authorities concerned suggestions to the function and making process of Korean economic policy.
