In this thesis, the writer has dealt with the theme "A Study on inflation problems of Korea". 1. It is unrealistic to expect that expansions in investment and other spending will have effects solely on employment and output. Changes in price levels must be expectes as well. The effect and causes of a general rise in prices and wages (i,e., inflation) and a general fall in prices (i.e., deflation) are vital. 2. Historially, prices have shown their greatest fluctuations in time of war. But recently the trend in price seems to have been more of a one-way climb: the absence of a drop in prices following world warⅡ and Korea war is perhaps a sign that modern mixed economies are no longer likely to tolerate legthy periods of unemployment, soft business conditions, and falling prices. Creeping "cost-push inflation is a new disease distinguishable from conventional demand-pull inflation", in which too much money spending (too much C+I+G or, what is the same, too much MV) bids for the limited supply of goods and labor available at full employment and pulls up price and wages. 3. Slow price increases are one thing. But when each increase in prices becomes the signal for an increase in wages and costs, which again sends prices up still further, we may be in the midst of a malignant, galloping hyper inflation. 4. Goals of long-term price behavior. 1) Prices-on the average- are to be stable. 2) Prices are to be gently rising. 3) Prices are to be falling steadily. But factors of inflation in Korea is attributable to compound function of increase of the currency, increase of demand, and continuous increase of expense. Thus inflationary factors continue because the fundamental factors bring out this exists inside of modern economic society. The fundamental factors are as follows. 1) Offering service of economy. 2) Comprehension increases influence of group. 3) Humanistic economy management. 4) The continuous increase of government roles. 5. We must consider a counter-measure on Korean inflation as follows. 1) Price policy for agriculture-marine products industry. 2) House and land policy 3) Monetary policy 4) Stock policy for the principal goods as petroleum resources. 5) Free policy for imput. 6) Administration policy of total demand. (price policy) 7) Growth policy 8) Income and indexing policy. 9) Reasonable exchange rate. 6. In case of pursuit the elements of galloping rising of land price is to be galloping economic development and the quick development policy. Therefore, we must find out settlement course in case of whole economic policy. 7. I've indicated the model of land decision and demand price, supply price, evaluation price etc, and researched for the land policy. Economic subjectors must break their consciousness from psychology of inflation of present day.

The following are some of the official responsibilities which the professional managers assume for specialized utility of the economic division of labours. (1) Choosing and arranging the personnel in accordance with the executive ability. (2) Helping to promote technical level to the highest degree. (3) Increasing the efficiency. (4) Standardization of commodities to make possible the mass production. (5) Improvement of the goods quality. (6) Economizing the time and labour. (7) Distribution of goods and skill. (8) Spurring for large-scaled plant. The technical experts are so essential to the successful technical innovation that the investment for its purpose is keenly needed. Accordingly, in order to educate both the technicians and the professional managers, the analysis of duties and the plan for educational training as well as the estimation concerning its effects should be examined. 1. Analysis of duties. There are some kinds of analysis of duties for educational training. In general use are one of the analysis of duties elements in which the estimation of duties is applied to the determination of wage and the other for recording the details of duties also applied to design, choice and distribution. Although the above-mentioned kinds of analysis are applicable enough to the plan for educational training, in its case it is recommended that the following should be emphasized on: a) The duties should be recorded in details. b) The analysis of work should be performed. c) The outline of training should be given. 2. The management of the plan for educational training. The management of the plan for educational training is the most important part of the concerned. For its effective and successful execution the following matters would be recommend: a) the preparation of training items. b) the preparation of training schedule c) the arrangement of training environment and its allotment d) the computation of educational training group. e) the training period fixing 3. The effects of educational training and its estimation. a) The greatest effects should be brought on the least expenditure. b) The standard for effects should be prepared. c) The actual measurement should be taken d) The desirable results should be expected. 4. Each of the enterprises had better, on its own account, run the training program for the professional management and the technicians. In case that it is not possible, however, it is the most desirable the governmental institute or the training schools attached to college take part in the program comprehensively in each sphere. It is also recommendable to establish a foundation for the joint training school managed in cooperation with each other of the enterprises. 5. From this time forward we must establish the independent system of professional technical development. Accordingly it can be expected that the promotion of independent research for the professional technical development would bring about the effects of killing two birds with one stone that we are able to the succeed in the technical innovation and also get to the advantageous ground for the hopeful induction of foreign technique.

A study on the meander characteristics of rivers is very important problems in a point of view river disaster protection and river preservation. But meander processing cause is not established a theory. The purpose of this study is to examine the meander characteristics for the Bosung River and Hongchun River. This study includes relationships between meander characteristics factors and stream order, among meander factors, i.e. meander length, meander belt, etc. Channel shape factor which is the ratio of the length from the starting point to the end to the channel length, tortuosity which is the ratio of the curved channel length against the channel length are well correlated with channel length, and meander gradient have to be important measure of river meander. The results of regression analysis of stream order and meander length and meander belt show linear relationships for the Bosung and Hongchun River.

Urban economics in application economics department is a very important duty which can settle urban many problems and urban economy subjects. Urban management in regional development and it's image takes overlap between them, and urban management was the past days used as means to regional development, but originally urban management is not thus, convenience things, but it is synthesis science which enlarges effective and welfare whole quantity for the citizens to league with optimum system through whole urban community space system and it's economy system, and social system. Viewed with this, the author has attempted to research a role of urban community and urban development, and problems of urban management. Urban problems appears rapidly by urban development and industrial urban community, and as a result of this, they appears occured to problems improvement of the slums, increasing worse houses, sudden increase in the traffic, increasing of popuration, and urban load development etc. But after that, in the latest date, the main theory of urban economics is analysis of economy power and problems which look for the certain law through a full urban phenomenon, and subjects of urban management. They are, that is 1. policy decision process for urban management 2. scientific method for management 3. introduction of accounting for enterprise 4. operation of PPBS etc. Urban community themselves must make rationally the efficient use of limited resources and needs practical effort to account of optimum supply in a state of equilibrium of public goods. The following are three policies for above practices. 1. Ordinary and capital expenditure are a design of integration conclusion, appropriative in conception of long-run finance administration. In this point, it is suitableness that include public enterprise accounting method. 2. First of all it is that grasps the movement of popuration and to presume social economy urban design. It needs to search the grounds of rationalistic expenditure burden and administration expenditure and to attempt cost - Benefit analyais and administration expenditure for citizen, as much as possible. 3. One of urban community must plan the management at operation of economic area and district area being different from administration area that is, conference, adjustment and contract etc. of the special survice between the other neighbour urban community in a wide administration scheme. This paper attempts to investigate the practical subject of urban management through many resources, and pursued future urban emage through the development of urban construction model, public development and information system. In addition to this, future urban emage is human environment and international information urban community, especially the heart of problem is civic subjectivity urban community in them.

A comparative study was undertaken to evaluate the contact Neodymium : yttrium aluminum garnet(Nd : YAG) laser system for vascular anastomosis of small caliber blood vessels(diameter 0.5-1.2mm) in the animal model. In this study 40 femoral arteries and 40 femoral veins of Sprague-Dawley rats were anastomosed by contact laser assisted microvascular anastomosis(LAMA) utilizing 3 stay sutures which were placed 120 degrees apart and the intervals welded with contact Nd : YAG laser unit, conventionally sutured anastomosis(CSA) served as controls. The time needed for vascular anastomosis, patency rate (immediate postoperative, postoperative 2nd day, postoperative 1 week, postoperative 4 week), gross and microscopic evaluations were compared to conventional microsurgical suture technique. The results are as follows : (1)Post-operative patency rate was 82.5% for femoral artery and 75% for femoral vein by contact LAMA technique compared to 90% and 75% by CSA technique at post operative 4 weeks. (2)Less time-consumed for arterial anastomosis by 6 minutes 23 seconds and venous anastomosis by 8 minutes 55 seconds with contact LAMA technique compared to CSA technique. (3)Grossly almost complete healing had taken place by post-operative 1 week by contact LAMA technique. (4)Aneurysm formation was 5% for femoral artery and 15% for femoral vein by contact LAMA technique compared to 5% and 10% respectively by CSA technique. (5)Microscopically, re-endothelization was complete by post-operative 7th day by contact LAMA technique. There was less medial hypertrophy and hyperplasia and also less inflammatory response compared to CSA.
