After the Cold War was over, the Korean-Japanese relations are experiencing radical changes. While the potential cooperative factors between two nations in politico-security and economic fields weaken, bilateral conflict issues such as so-called 'past history problem', fishery and territorial friction are being revealed. In order to overcome this situation rationally, two governments are required to build up the co-perception framework to cope with conflict issues smoothly. Especially the conflicts concerning 'past history problem' and the bilateral coordination of attitudes toward the North Korea policy are very important issue areas which should be settled down in the near future. This paper provides the objective analysis and desirable policy orientations about the two issues from the point of view of the Korean side. Firstly, 'past history problem' is one of the most serious issues which deteriorated the bilateral relation severely since 1980s. It is obvious that the frequency of conflicts concerning the past history problem between two nations have gradually increased since cold war system was collapsed. Why was this phenomenon occurred? This paper answered the question by pointing out the three factors, say, first is the deconsolidation of the bilateral relations since the collapse of cold war in the context of politico-security area, the second is the intensification of domestic struggle concerning the perception of the past history between the right-wing and the liberal group in Japan, and the third is the stem and hard-line response of the Korean side to the past history problem. Thus this paper suppose that it should be desirable for the Korean side to take more flexible and strategic stance as far as the issue concerned. It is impossible to settle down the issue completely by the any kind of short term measures. Therefore we should make efforts to solve the problem by means of multilateral approach, say. the formation supra-national solidarity at the level of civil societies or setting the issue as the international agenda at the global society. Secondly, the incorrespondence at the North Korea policy between two nations came up to the surface as the serious problem. The Korean government since the appearance Kim Dae-Jung administration is consistently seeking to appeasement approaches toward the North Korea below the slogan named "Sunshine Policy". In contrast to the this approach. the Japanese government is taking a series of hard-line North Korea policies. It is needless to say that Japan's stem policies toward the North Korea was originated from the uncompromising and hostile activities of the North Korea such as the kidnapping incidents. and the unexpected mid-range missile test across the Japanese territory. In spite of the gap of the interests of two nations, it is essential to make common efforts to alleviate the hostile attitude of the North Korea for the peace and security in northeast Asia area. In this context, we need to give impetus for the Japanese government to resume the normalization negotiation. suspended since 1992. with the North Korea, and take a positive role in KEDO project herself.

Objective: To evaluate nasal and upper lip changes after Le Fort I surgery by means of images taken with a three-dimensional computed tomography (3D-CT). Methods: Fifteen patients (9 female and 6 male, mean age 21.9 years) with preoperative and postoperative 3D-CT were studied. The patients underwent maxillary movement with impaction or elongation, and advancement or setback. With the 3D-CT which presents reconstructive soft tissue images, preoperative and postoperative measurement and analysis were performed for nasal tip projection angle, columellar angle, supratip break angle, nasolabial angle, interalar width, internostril width, columella length and nasal tip projection. Results: Postoperative interalar and internostril widening was significant for all categories of maxillary movement. However, there was little significant relation in all parameters between the amount and direction of maxillary movement. Interestingly, movement of the maxilla with upward did show a little decrease in the columellar angle, supra tip break angle and nasolabial angle. Also movement of the maxilla with forward did show a little advancement in the upper lip position. Conclusion: Changes to the nose clearly occur after orthognathic surgery. There was a significant increase in postoperative interalar width and internostril width with maxillary movement. However, no clear correlation could be determined between amount of change and maxillary movement. Interestingly, maxillary impaction did show a little decrease in the columellar angle, supra tip break angle and nasolabial angle. In addition, we used 3D-CT for more precise analysis as a useful tool.

Purpose: The purpose of this study is to test the efficacy of various methods of fat harvesting in animal model by viability comparison with assay including cell counting, MTT assay, and histologic evaluation. Materials and methods: New Zealand white rabbits experiments were used. Groin fat pads were subjected to different harvest method varying ingredients of solution(Experiment 1: T1 solution= lidocaine 1000mg/L, epinephrine 1mg/L, sodium bicarbonate 10mgEq/L, Triamcinolone 10mgEq/L; T2 solution=lidocaine 1000mg/L, epinephrine 1mg/L, sodium bicarbonate 0mgEq/L, Triamcinolone 0mgEq/L) and pressure exerted on harvesting with Luer-Lock syringe connected to suction cannula.(Experiment 2: P1 group=3cc intermittent pressure; P2 group=10cc sustained pressure) Fat cell viability was assessed with cell counting with a hemocytometer, MTT assay, and histologic evaluation. Results: Experiment 1 Cell count: T1=2.4/3.4/4.2, T2=9.6/8.4/7.2($\times10^5$ per mL); MTT assay: T1=0.516/0.41/0.453/0.412/0.421, T2=0.925/0.765/0.54/0.634/0.614 in 21 days(absorbance); Histology: T1 showed elongated and, different in size and shape, and ruptured adipocytes with only a few normal adipocytes whereas T2 showed central core of fat with almost intact fat cells Experiment 2 Cell count: P1=1.2/3.2/4.2, P2=1.2/2.4/3.8($\times10^5$ per mL); MTT assay:P1=0.256/0.245/0.258/0.21/0.264, P2=0.12/0.231/0.245/0.313/0.281 in 21 days(absorbance); Histology: P1 showed somewhat evenly distributed normal-looking fat cells and P2 showed relatively irregular shape of fat cells with small blood vessel amongst adiopocytes. Conclusion: Viability was higher in ‘modified tumescent solution’without sodium bicarbonate and triamcinolone and we also found no significantly different viability between using intermittent pressure and using sustained pressure. But in terms of initial viability of fat cell, we can assume that lower intermittent pressure would make better clinical results.

Il Woong Cleft lip and palate foundation was founded in 1968 by Professor emeritus Byoung-Il Min. Since then the foundation has operated numerous cleft lip and palate patients not only in Korea but also in under-developed countries such as Vietnam, China, and Cambodia. In December 2005, the foundation was allowed as an incorporated association by Ministry of Foreign affairs and Trade, so that it could have official status. From March 6th 2009 to March 14th 2009, we conductp,d charity cleft lip and palate operations of 23 patients in areas of Deozhou, China. Hereby we present the results of operations.
