The Association of the Southeast Asian Nations(ASEAN) is economically important not only as the vast commodity market but also as the provider of natural resources. Japan established her economic hegemony through early advances into this area. There have been the two kinds of assessment on the Japanese investments into this area. One is that the Japanese economic penetration made ASEAN the economic vassal of Japan while the other that this contributed to the economic prosperity of this area.. The present study therefore examines the motivation and reality of the Japanese economic, and political advances into this area in order to explore some sueful lessons in the formulation of our ASEAN strategy. Initially, the Japanese investments towards ASEAN concentrated on resource developments. The pattern of the Japanese investments in the area, however, has changed dramatically in its magnitude and characteristics. In the 1970s and early 1980s, the Japanese investments amount to 400 millon dollars as annual average. It increased 900 million dollars in 1984 and 1,524 million dollars in 1987 respectively. At the same time, most investments were transformed from import-substituting industries to export industries. The investment boom since the middle of 1980s has been due to the high value of Japanese yen and trade conflicts between Japan and the US. Viewing the annual trends of Japanese investments, one can see its annual increase of over 70% until 1990 and its decrease since then. This contrast with Japanese investments towards China which has increased rapidly since 1991. However, Japan's ASEAN investments has increased again in 1994 due to the high value of yen. The decrease of Japan's foreign investments in recent years has been due to the such multiple factors as the disappearance of bubble economy, cosequent economic recession, the increases of wages on the part of ASEAN countries and the emergence of China as an attractive site of foreign investments. Several lessons can be drawn as the result of the analysis on the Japan's advances into ASEAN: 1) The pattern of our ASEAN investments which have been simple assembling production of labor intensive consumer goods should be corrected. 2) Industrial reordering master plan should be devised not only in ASEAN but also in south Asia, and China. 3) Joint ventures with local partners rather than individual investments should be promoted. As for the Japan's political relations with ASEAN countries, Japan was able to penetrate economically into ASEAN as a result of the US's cold war policy. During the cold war periods, Japan could not have diplomatic autonomy due to her pursuit of the US's cold war policy. In the early 1970s when detente began as a result of the US-China rapproachment, Japan was able to have some diplomatic autonomy towards the Southeast Asian countries. Due to the rapid economic advances into the ASEAN countries on the part of Japan, the anti-Japanese riots during Prime Minister Tanaka's 1974 visit to ASEAN occured. It followed closely on the heels of the oil embargo. The demonstrations showed that Japan was alienated from some of its neighbors, whose importance as raw material providers had just been highlighted by the oil embargo. In this situation, Japan needed a new Southeast Asian policy. This new policy was crystallized in the Fukuda doctrine. The Fukuda doctrine enunciated that Japan would play a mediating role between ASEAN and the Indochina countries. Although Japan failed its mediating role because of the Vietnamese invasion into Cambodia, she played a significant role in the peaceful settlements of the Combodian confilicts and in the Asian Pacific economic cooperation. In the post cold war periods, Japan will continue expanding its political role in this area. as a junior partner of the US. Korea should cooperate with the ASEAN countries in order for the US to remain in the Asian Pacific area.

온도 변화가 교정용 니켈-티타늄 호선의 하중값에 미치는 영향

천경애,임성훈,김광원 대한치과교정학회 2007 대한치과교정학회지 Vol.37 No.6

초탄성 니켈-티타늄 호선의 하중값은 온도 변화에 따라 변화함이 보고된 바 있다. 따라서 본 연구에서는 온도가 변화함에 따라 니켈-티타늄 합금 호선의 하중값이 어떻게 변화하는지 알아보고자 하였다. 37℃ 항온 상태에서 0.016" x 0.022" 니켈-티타늄 호선을 3.1mm까지 변위시키는 3점 굴곡 실험을 시행하여 하중 시와 탈하중 시의 1.5mm 변위지점의 하중값을 측정하고 이 지점에서 구강내 온도 변화를 고려한 온도 변화 실험을 시행하였다. 20℃ 저온수 또는 50℃ 고온수를 호선에 흘려보냄으로써 온도 변화를 주었다. 저온 실험은 저온수로 온도 변화를 주고 37℃ 항온 온도로 회복된 후에 다시 저온수를 흐르게 하는 방법으로 10회 시행하였고 고온 실험도 동일한 방법으로 시행하였다. 그 결과 하중 시 1.5mm 변위지점의 하중값은 저온 실험 및 고온 실험 후 37℃로 회복된 후에도 모두 감소된 값을 유지하였다. 반대로 실제로 치아에 가해지는 교정력으로 생각되는 탈하중 시 1.5mm 변위 지점의 하중값은 저온 실험 및 고온 실험 후 온도가 37℃로 회복되어도 모두 증가된 값을 유지하였다. 이상의 결과를 종합해 볼 때 온도변화를 거친 후 초탄성 니켈-티타늄 합금 호선의 하중 시 힘은 감소하였고 탈하중 시 힘은 증가되므로, 임상에서 니켈-티타늄 호선을 적용 시에는 37℃에서의 하중-변위 곡선에서 나타나는 힘에 비해 더 작은 하중 시 힘과 더 큰 탈하중 시 힘이 적용될 수 있음에 유의하여야 한다. Objective: The purpose of this study was to evaluate the influence of intraoral temperature changes on the orthodontic force level of a superelastic nickel-titanium alloy wire. Methods: Nickel-titanium archwires of 0.016" x 0.022" thickness were tested with a three point bending test setup, and temperature changes were applied. The force level changes according to temperature changes were measured at a 1.5mm deflection during the loading phase and a 1.5mm deflection during the unloading phase from a deflection to 3.1mm. Ten cycles of thermal cycling from baseline (37℃) to cold (20℃) or hot (50℃) temperature were applied. Results: After thermal cycling, the force level during the loading phase decreased and the force level during the unloading phase increased even after the temperature was changed to the initial 37℃. Conclusions: The results suggest that the orthodontic force level can not return to the initial force level after temperature changes. When applying superelastic nickel-titanium archwires, we must consider that a lighter force than the loading force and a heavier force than the unloading force will be applied after intraoral temperature changes caused by eating and drinking.

수정시편을 300℃, 400℃,500℃,530℃에서 각각 20시간씩 열처리한 후에 X밴드 전자 공명장치를 사용하여 α-수정내의 S?(1).S?',S?'' 세 공명중심들에 대한 열처리 조건에 따른 공명 신호들의 세기의 변화를 상온에서 조사하였다.열처리 효과로 S?'과 S?'' 공명중심들이 일부 S?(1)으로 전환되었다. 480℃에서 수정시편의 c축 방향으로 15ooV/cm의 전기장을 가하여 시편내에서 +1가의 보상이온들을 빼내거나, 500V/cm 와 1000V/cm의 전기장으로 Li+ 이온과 Na+이온을 각각 주입시킨 후에 공명신호들의 세기를 서로 비교하였다.한편 시편내에서 보상이온들을 빼내지 않고 400℃에서 20V/cm 와 50 V/cm의 약한 전기장으로La+이온을 주입시킨 경우와 200V/cm의 전기장으로 Na+이온을 주입시킨후에 공명신호들의 세기가 변화하는 모습을 조사하였다.Li+ 이온이 시편에 주입됨에 따라 세 공명중심들 모두 공명신호들의 세기가 증가하였으며, Na+이온이 주입된 경우에는 공명신호를의 세기가 크게 감소하였다. 열처리 효과와 전기장 처리의 결과로부터 세 공명중심들 모두 Li+이온에 의하여 전하가 보상되는 것으로 판명되었다. After heating a quartz sample for 20 hours at 300℃, 400℃, 500℃, and 530℃, respectively, the changes of resonances signal intensities of the centers S?(1), S?', and S?''in α-quartz according to the conditions of heat treatments were investigated at room temperature by employing an X-band electron spin resonance spectrometer. The centers S?' and S1'' were partly converted into S?(1) by the effect of heat treatments. After extracting positively monovalent ions from quartz samples by applying an electric field of 1500V/cm along the crystal c-axis at 480℃ and after electrodiffusing Li+ ions and Na+ ions into the samples with applied electric fields of 500 and 1000 V/cm, respectively, the intensities of resonance spectra were compared with each other. On the other hand a quartz sample was electrodiffused with Li+ ions at 400℃ with weak electric fields of 20 and 50V/cm and then implanted with Na+ions with an electric field of 200V/cm.As Li+ ions diffused into the sample, the intensities of all the three centers increased. But in the case of electrodiffusion with Na+ ions the resonance signals decreased by considerable. From the effect of heat treatment and the result of electrodiffusions it is proved that all the three centers are compensated by the Li+ion.

政治, 經濟, 經營的 側面에서 考察한 日本의 發展戰略에 관한 硏究

The purpose of this paper is to explore the key factors which brought on the Japan's high speed economic growth in the postwar periods. There are largely two approahes which deal with this issue: the state-business relations and the Japanese style management. This study undertook critical reviews on the existing literatures. There are four models in the state-business relations: bureaucratic-led devlopment model; market oriented model; network model; and corporatism. Considering industrial policy as only state intervention into the market, all four models was not able to explain fully different policy patterns in the respective industrial sectors. Acordingly, it is more relevant to consider industrial policy as conflict resolution among actors, existing in the state and market, who realize their interests respectively. In this context, one has to understand policy network patterns in the respective industrial sectors which emerge out of interactions among not only bureaucracy's industrial strategy but also business' strategy, cooperation and competition between business and bureaucracy, and poitician's intervention into the industrial sectors. In the managerial perspectives, not only life employment system, seniority system, corporate union system but also relational theory, technological development, production system were analyzed.

문규춘,김훈,한상엽,박광채 조선대학교 에너지.자원신기술연구소 1999 에너지·자원신기술연구소 논문지 Vol.21 No.2

B-ISDN using ATM should provide QoS of various service and also fair control for each source. In this paper, we suggested the Virtual-Time-based Round Robin(VTRR), fair scheduling algorithm guaranteeing demanded QoS. We searched the characteristic and required points possessing proper fair scheduling algorithm in high speed network. And we analyzed the performance character and simulation. The result is that VTRR is much simpler in algorithm and is better than WFQ or GPS in performance.

The effect of nucleants was studied on the mechanical property and corrosion resistance of phosphate refractories used for high temperature inorganic binder It was found that a mixture of TiO₂ and ZrO₂ nucleants yielded not only the best corresion resistant but the highest strength phosphate refractory. However, the effects of nucleants on the mechanical property of the refractories could not be identified in this study because each sample showed different porosity which was also presumed to affect the fracture strength of the refractory.
