      • 경제발전하의 안정화정책 : 제1차 경제개발 5개년계획의 경험에 비추어 With Respect to the First-Five Year Economic Plan

        임종철 성균관대학교 사회과학연구소 1968 社會科學 Vol.7 No.1

        To maintain economic stability and sustained economic growth is the main objectives of our economic society. However, it is hard to expect that these goals can be always realized any time and anywhere. In fact, economic policies to implement these two objectives seem to be highly complementary by its intrinsic nature, yet sharply conflicting each other in practice. Our experiences indicate that some country can attain a rapid stable growth; some country, by intensifing these conflicts, yet obtain a rapid growth of an economy. It is also learned that in some countries, the - primary emphasis is placed on stabilization policies at the expense of economic growth. Amongst these alternatives of economic policies, what is the best one depends entirely on the social welfare function and the ultimate value towards it taken by decision makers of economic policies. Nevertheless, a generalization is easily made that stabilization policies are the primary goal of economic policies where wealth is so much accumulated in advanced economies while the $quot;growth-first$quot; policies are the primary targets in developing nations. Such a generalization might seem to be justifiable. However, our experiences indicate that such an generalization is, in fact, extremely difficult one to make. One of the main reasons is that unstabilizing factors are expected to be inherent in developing countries more than in advanced countries, because of the fact that there exists growth potentials in underdeveloped economies. Such inherent unstabilizing factors are as follows. 1. Unstabilizing effects are easily expected when the pattern of wealth composition of an economy is changing. 2. When investment demand is increasing, inflationary pressure might be taken place. 3. There is a widening gap between the living standard and increase in the level of productivity. 4. In a rapidly growing economy, structural changes are easily expected to be occurred. 5. When development plans are formulated with regionally bias within an economy, this might lead to create unstabilizing effects. 6. If the government takes discretionary policies of development plans, this leads to create unstabilizing effects in an economy. Therefore, unless the above effects were completely eliminated or minimizing such effects inherent in a process of economic development, self-sustained economic growth of an economy can hardly be expected. Let us consider stabilization policies necessary to eliminate the above effects. 1. When the pattern of wealth composition of an economy is changing, the government should control investment activities. Therefore, selective investment-control policies are required to stabilize an economy. 2. When an economy is under inflationary pressure, basically caused by an increase in investment demand, expansionary policies should be curtailed by the government to use monetary and fiscal measures properly. 3. In order to wipe out the gap between the living standard and the increase, in the level of productivity minimum standard of living on the part of wage-earners should be maintained. 4. In fact, structural change of an economy is primarily concerned with long-run aspects of economic development. Therefore, the scales of operation in medium-size industries should be changed in order to be optimized. 5. In order to eliminate the regional difference of development it is necessary for the government to carry out decentralization policies of development so that potentiality of medium size industries should be fully utilized. Income equalization policies through fiscal measures are also necessary to increase effective demand of the economy as a whole. 6. In order to mitigate discretionary policies taken by the government, policy criteria should be rationalized in line with economic reasoning. Once a criteria is specified, policy instruments reqnired for the criteria should be used efficiently. Above all, it is needless to say that a set of development projects and policies should be coordinated. I have pointed out the measures necessary to maintain a stable growth in the context of Korean economy. In underdeveloped countries, to make realization of all such measures into effect can be hardly expected, because of lack of administrative techniques of government in underdeveloped countries to implement such measures of development planning. Yet, efforts trying to pay to implement such measures by our government will certainly contribute to maintain economic stability and economic growth of our economy.

        A Blockchain is a type of distributed ledger system that consists of a large number of nodes. A block is a container in which transactions are included, and the transactions can be recorded in chronological order by chaining blocks. To work properly, it is essential that the nodes in the Blockchain system have the same image of the chained-blocks. Blockchain systems use various types of consensus algorithms to achieve the same states among the nodes, and the fundamental elements in these algorithms are proof of work and the main chain selection policy, particularly in permissionless Blockchain systems. However, consensus algorithms for permissioned Blockchain systems can be completely different from those of permissionless blockchain systems. In this paper, we overview the basic working mechanism of consensus algorithms, and briefly introduce a few that are currently being applied.

        자동차 부품 기업의 물류시스템 개선 방안 연구

        임종철,강경식,Lim, Jong-chul,Kang, Kyung-sik 대한안전경영과학회 2017 대한안전경영과학회지 Vol.19 No.1

        Currently, Korea is actually increasing and increasing demand for leisure such as parts for A/S of automobile parts of the car, as well as trends in borrowing and finished parts are also required a steady increase in automobile traffic daetsu. There is one car and want to be driving a car A/S parts supplier smoothly for many years and that it is often the case if it is not supplied in a timely fashion, it is a reality that many eonseong hear from customers. These symptoms can be confirmed that the logistics systems of a system of selling auto parts supplier but above all a problem for several reasons, which will be considered as areas for improvement should be done urgently. Enterprises internally cooperation automotive supplier, but the need to get out to re-examine urgently complemented by the logistics system of systems to allow better respond to complex environmental changes of our customers grow, and now also the proliferation of small ship-run screen and Darvin, there is increasing distribution and logistics services, including logistics costs as a lack of work force that the company is itgetda can be called by the reality that the chances of getting a lot of jeyakreul own growth. Given this situation, the procurement of logistics enterprises. In-house logistics. Classified as sales logistics examined the long-term improvement of logistics distribution networks based on this part to derive into the problems of logistics and parts distribution system of Korean auto parts dealer.

      • 모래지반내의 연직 지반앵커 표면의 마찰각

        임종철 한국지반공학회 1995 지반 : 한국지반공학회지 Vol.11 No.4

        본 연구에서는 정규압밀 건조 모래 지반내의 연직 강체 지반앵커에 대한 모형 인발실험을 실시해서 앵커 표면의 마찰각을 실측했다. 마찰각은 앵커 표면의 깊이 방향으로 설치된 다수의 2 방향 로드셀을 사용해서 측정된 수직응력, 전단응력으로 구했다. 실험은 평면변형률 앵커와 축대칭 앵커에 대해서 실시했는데 실험 분석 결과, 앵커표면의 최대마찰각은 평면변형률 압축시험에 의한 무신축방향의 면상의 응력경각의 최대치와 거의 일치한다는 것을 알았다. 이 결론은 모래의 강도 이방성과 구속압 의존성 등을 고려하여 얻은 것으로 앵커 표면 마찰각에 모래의 전단저항각을 적용해서 설계하면 위험측이 된다는 것도 알 수 있다. In this study, friction angles on the surface of vertical rigid ground anchor in normally consolidated dry sand were measured by model pullout tests in laboratory. Friction angles were obtained from the normal and shear stresses measured along depth of the anchor stir face by attaching several 2-dimensional load cells. Model tests were conducted under the plane strain state and axial symmetric state. From the results of tests, it was concluded that the maximum friction angle on the anchor surface coincides nearly with the maximum angle of stress obliquity on the plane of zero-extension direction obtained by plane strain compression test. This result was made with regard to the strength anisotropy and stress dependency of sand. It showed that when angle of shear resistance of the sand is applied to the friction angle of the anchor surface, the design capacity could be less than the applied force, thus making the anchor unsafe.
