Automobile industries have been developed rapidly mainly as a key manufacturing industry. On the other hands, atmosphere pollution is getting worse noticeably than in any other times. In the diesel emission, PM(Particulate Matter) and NOx(Nitrogen Oxidation) have been exhausted with a great amount and the regulation is getting stringent. In order to develop a low emission engine, it is necessary to research on better quality of fuel. Sulfur contained in fuel is transformed to sulfur compound by DOC(Diesel Oxidation Catalyst) and then it causes to increase of sulfate-laden PM on the surface of catalyst. Recently diesel automobile industries are focused on the development of reduction techniques on PM by modifying combustion of sulfur in fuel. In this research, ULSD(Ultra Low Sulfur Diesel) is used as a fuel and some experimental results are investigated. ULSD can reduce not only PM but also gas materials because cetane value, flash point, distillation 90%, pour point and viscosity are improved in the process of desulfurization. However, excessively reduced sulfur may cause to decrease lubricity of fuel and engine performance in fuel injection system. Therefore, it requires only modest adjusted amount of sulfur can improve engine performance and DOC, as well as decrease of emission.

Highly developed modern capitalism requires the machine system of states with positive and various functions. This means the substantive formation of fundamental policies and strong tendency of dependence towards the administration for the decision of the national affairs. With this changing aspect the chief national issues are mostly decided by the administrative functions which monopolize the public informations and supreme powers. Also this administrative states produces the transition of the present system of administration and charactrizes the structure of modern states. The result is that modern capitalistic states are being under the control of the "administrative states" whatever the systems they have maintained so far. Today democratic free nations, having complicatedly industrialized show the unavoidable characters; positivism, formalization, functionalism, professionalism, technocracy and massiveness. Accordingly the trend is that the modern states are going far from the last system-the separation of three powers of governments, and the administration means much. Now the national and international affairs are becoming complicate, formidable and professional, changing rapidly. These require the rapid establishment of the policies and executing them by the administration. In spite of the written records of the separation of three powers and their constraint on each other in the constitution real political performance are increasingly being carried out by the administration itself. In conclusion the democratic free nations would persist in preserving the superior position of administration now on. Realizing these problems I am going to revise the followings, especially studying the administrative states of Western Germany. 1. The background and the base of the administrative states. 2. Realiy and norm of modern administration and its organization. 3. Present standings of administrative states.

Recently, air pollution is increased according to increase of vehicle. So many countries are studying about compressed natural gas engine. Research on the development of CNG dedicated engine that has important meaning both as a clean fuel and an alternative energy to reduce the exhaust emission from diesel engine are actively going on these days. In this study, the characteristics of CNG engine was investigated and the engine performance experimented by changing the parameters such as boost pressure. The CNG engine performance and exhaust emission were measured by engine performance mode at maximum load condition with increasing the rpm in the range of 1,000 ∼ 2,200rpm. The exhaust emission was also measured at D-13 mode and compared to the emission regulation.

We have carried out the field compaction tests in the site in which the high rock fill embankments are going to be constructed about 25m in height, to examine the effect of the soil fraction to the total embankment materials which are the mixture of rock fills and soils on the degree of field compaction. We have made four sets of in-situ concrete boxes of the size of 1.5m×1.5m×0.6m to obtain the maximum dry density of total embankment materials after compacting by using a 10-ton vibrating tamping roller. We have found, as a result, that the optimum passing number of the roller to yield the 90% of relative compaction economically attainable has appeared to be 8 passes, and that the percent of the soil fraction to the total embankment materials to yield the 90% of relative compation in the field has appeared to be 41.78% by weight.

Abstract Financial slack refers to a firm's excess holding of liquid assets above what is necessary for the normal operation. There are still controversies about why firms should maintain financial slack and what the optimal amount of financial slack is. In imperfect market, financial slack becomes relevant to the firm value through the effect of tax, agency problem, information asymmetry. This thesis examined the effect of information asymmetry on the level of financial slack. It was found that R&D investments have positive effects on the financial slacks.

Until rexent times, regional development policy of our country has focused on the metropolitan area and the growth of industry. Therefore, rural community has been confronted with underdevelopment to the contrary. But, it is difficult to consider a balanced development of our country without having a new understanding of local area. In the near future, our country will enforce a local automony having been held back for 27 years since 1961. From now on, citizen must assume leadership of community development, participation in it suvjectively and voluntarily. The purpose of this study is to explore the device for effectiveness of citizen participation in sub-region development. To quarantee citizen participation in sub-region development effectively it is required to expand chances for citizen participation, to cultivate qualities of participatiors (citizens, public officials, planners), to institutionalize citizen participation and finally, to study this subject continuouslly.

Studies on the turbocharger itself or various aspects generated from turbocharged engine have been made. However, only a few researches have been made on the performance for the natural aspirated engine equipped with the turbocharger and the intercooler. In this study, the performance prediction program based on turbocharger theory is developed for simu-lation which may reduce the cost and the trial-and-error time. The program is verified with the experimental results for 11,000cc diesel engine with the turbocharger and the intercooler. Also, various factors which are invisible in experiment are predicted using this program.

배당정책과 주식평가모형 : Review of MM Theory MM이론의 재조명

AbstractMiller and Modigliani provided the theoretical foundation about the dividend policy. They proved, under perfect market conditions, the dividend policy had no effects on the firm's valu. MM's proof, however, has serious problems of tautology. MM used the accounting equation that the use fund dquals the raised fund, and that approach vagued the essential part of dividend policy. This article is aimed to suggest an alternative frame for proving the dividend irrelevancy theorem.

資産價格決定模型의 檢證可能性에 관한 硏究

The CAPM of Sharpe and Linther is the very popular asset pricing model because of its simplicity and its practicability. Many researchers tried to examine whenther the linear relation between the returns and the risks holds as predicted. The results, however, were somewhat contradicting. Especially those who found unsatisfacory results represented possible causes of such departures. And most of these causes were concerned with the assumptions upon which the CAPM is based. This paper examines the testability of the CAPM more basically. In section Ⅱ, the mathematic properties of the efficient set are derived. The testable hypothesis of the CAPM and its problems are described in section Ⅲ, and section Ⅳ contains the summary and the conclusion.
