Among many open libraries under the rule of the Japanese imperialism, only the railroad library as the character of special library under the control of the Japanese Government General is remarkable for having opened its facilities to outsiders as well as the interior users. This study tries a) To look into what were the colonial background, aim and motive of the establishment of the railroad library under the Japanese rule, b) To analyze its activities and the change of its organization, c) And to find out its vestiges an the effects which it has on our country's library circles. The following are the result: A. The railroad library under the rule of the Japanese imperialism functioned as a public library by the outside book's circulation rather than the interior using. B. The outsiders were qualified to use it only when they got the joint guarantee for the city resident, which means that the o n.0, pportunity of the circulation was not free for the Koreans rather than the Japanese. C. From the aspect of collections, technical books such as natural science, and reference ones tended to be collected, and their whole composition was focused on the materials for the Japan-Korea identification scheme and development of the national spirit as the Japanese empire's subjects. D. In the respect of its organization, all the clerical employees, as well as the chief librarian were composed of the Japanese. Although the Koreans were in principle prohibited from working there, a few of them were employed as guard or servant as the China-Japan War was close to the end. E. The area of the outside book's, circulation service was expanded throughout the whole region along the railroad connecting Pusan with Manchuria. Such a service activity which contained several meanings, was tried by means of culture's books, circuit's books, train's books, hotel's books, mind's development books and reader's reading books etc. F. Such matters as the limitation on book circulating and the quantity of circulation book, the paid circulation and the partial restriction on free circulation mean the wartime system under the rule of the Japanese imperialism and also a n.0, ppeared as a factor of hampering the Koreans from getting accustomed to using library, which has affected them until now. G. The noticeable thing in the service activity is shown in attempting the diversified and positive way of service like free circulation in order to solidify the attitude of the Koreans toward war by organizing mind's development books as well as culture's books with the China-Japan War. H. On the other hand, it can not be passed over that the diversified service activity of the railroad library played a role of bridge in turning of today's library circles of ours to the modernization.

In this study, the effect of thermal aging temperature on the weight loss, glass transition temperature, and morphology of epoxy adhesives cured with amine (D-230), amide (G-5022), and anhydride (HN-2200) was investigated. As a result, the weight loss of three specimens was increased with increasing the thermal aging temperature. The result was attributed to the thermal aging which was occurred at the surface of adhesive specimens at high aging temperature, resulting in increasing the weight loss of the specimens. According to the DSC result, the glass transition temperature of DGEBA/D-230 and DGEBA/G-5022 samples war increased as the aging temperature increased, whereas the glass transition temperature of DGEBA/HN-2200 samples was constant above aging temperature of $150^{\circ}C$ and aging tine of 7 days. The SEM result indicated that the surface of DGEBA/G-5022 specimen showed more rough topography than that of DGEBA/D-230 or DGEBA/HN-2200 specimen after thermal aging. This could be correlated with the result of weight loss.

As the technology hegemony war between the United States and China develops and the importance of R&D increases, countries around the world are increasing their R&D investment. In Korea, the size of R&D investment by the government and companies has steadily increased every year, and cutting-edge technologies are being developed in various fields as it shifts to the direction of creative technology development. However, the number of cases in which high-tech core technologies in Korea, which have invested a lot of budget, time, and effort, are illegally leaked overseas is also steadily increasing. Research security is an activity to safely protect protected objects in the research environment from risk factors such as leakage and deodorization, and laws and systems for research security are being reorganized not only in Korea but also in the United States and other countries around the world. In this paper we aims to derive Korea's research security policy direction, focusing on US research security cases which ranks first in R&D expenses around the world to improve the R&D system and actively discusses R&D policies and laws.

Because of the continuous growth of energy consumption, and also the tendency to site power lines and pipelines along the same route, the close proximity of power lines and metallic pipelines has become more and more frequent. Therefore, there has been and still is a growing concern about possible hazards resulting from the influence of power lines on metallic pipelines. This paper calculates the induced voltage of the pipeline which has the same right-of-war with 154kV and 22.9kV power cables in a tunnel. And propose the best phase order to minimize the induced voltage.

It is well known that polymer chemistry started by the study on cellulose. However, the study on cellulose has not made a significant progress after the 2nd World War, because the interest of researchers has directed to the newly developed synthetic polymer science. Recently the situation has been changing as suggested by the creation of a word "Cellulose Renaissance". This change is due to the recognition that cellulose is a renewable resource and a biodegradable, environmentally friendly material. In this lecture I'd like to introduce you some recent topics in cellulose chemistry which were reported by Japanese researchers.

Since World War II nations have formed alliances for reasons of security and trade. Countries have seen international integration as an appropriate approach to resolving domestic and international political issues, improving their welfare by both transforming their infrastructures and increasing their foreign trade. While the majority of these relationships are straightforward d Turkey's relationship with the European Union is more complex due to differences in religion and, at times, political ideology from other Union members. As a candidate country Turkey has made advances towards the full membership of the European Union with the customs union being the most significant. The impact of customs union membership is discussed and the effects of the customs union on Turkey's trade and economy are examined from a perspective of different economic theories.

To enhancing efficiency of hard chrome plating solution more highly, cathode current efficiency were surveyed connected with hardness of deposits, surface morphology, TEM analysis and corrosion test of anode materials. Efficiency war increased up to 26% values by adding catalyst and two kind of additives. With given bath composition and 6$0^{\circ}C$, 60A/d$\m^2$ electrolosis conditionss bright and micro cracked deposits were well obtained, which showed HV 1000 values. From corrosion tests, anode materials such as Pb-Te (0.02%) and Pb-Ag(1%) showed most anti-corrosive results. Through SEM micrograph observations, ef-fects of additives on levelling, brightness and micro crack properties of hard chrome deposits could be con-firmed. Also, through TEM analysis the fact that deposits from crack free solution or high speed solution were more fine than from sargent solution could be confirmed.

South Korea has had a rich history of independent thinking and self-reliance since the Korean Conflict. The war left the country the need for infrastructures in a variety of fields. Instead of relying on aid from foreign nations, however, key figures within South Korea's borders fathered the nation's first government-funded scientific and engineering institute, the Korea Institute of Science & Technology (KIST). Even though KIST encountered numerous obstacles, its commitment to research and development (R&D) would ultimately allow it play a crucial role in the rebuilding of the country. As a result of the institute's success, South Korea was able to move forward economically to become a beacon of hope for developing nations around the world.

Submarines are weapons systems that have been proven to be useful in battle since World War I and have continued to improve the efficiency of propulsion systems in order to be used efficiently on the battlefield. In particular, countries that unable to utilize nuclear propulsion systems make efforts to increase the efficiency of Air Independent Propulsion systems, and typical examples are fuel cells, Stirling engines and MESMA. It is also expected that the development of new propulsion systems such as hydrogen-reformer fuel cells, metal-air fuel cell and direct combustion propulsion systems will continue, so the characteristics of these will be examined and the performance based on the published data be checked in this thesis.
