Background: The most important factor in preventing sternal complications is stable sternal approximation. We have tried to find the most effective sternal closure method by examining the incidence of sternal dehiscence with or without infection in patients with cardiac surgery through median sternotomy. Material and Method: This study was performed in 489 patients over 45 years of age with median sternotomy for open cardiac surgery. Simple closure with interrupted 6 wires was performed in 159 patients, figure-of-8 closure technique in 119, overlapping interrupted closure using 10 wires in 150, and combined closure technique of interrupted simple closure and figure-of-8 suture closure in 61. Two hundred thirty-four patients underwent valve and aortic operations and 213 patients coronary artery bypass surgery. Result: Sternal dehiscence with or without infection occurred in 12 (2.5 %) patients. The complication developed in 5 of 159 patients (3.1%) with six interrupted simple closure, in 4 of 119 patients (3.4%) with figure-of-8 closure, and in 3 of 150 patients (2.0%) with overlapping interrupted closure using 10 wires, but there was no complication in 61 patients with combined closure technique (relative risk for other closure techniques, p<0.05). There was no significant difference in the incidence of the sternal complication between valve and aortic operation group and coronary artery bypass group (3.0% vs 2.3%, not significant), but diabetes mellitus was a significant independent risk factor (odds ratio and multivariate analysis, p<0.05). Conclusion: The sternal closure technique that combines simple interrupted suture closure and figure-of-8 suture closure may be a more useful technique to enhance sternal stabilization compared to other closure techniques, such as simple interrupted closure, 8-figure closure, and overlapping interrupted closure.

The study area in the East Sea is located on the northeastern margins of the Ulleung Basin near the Kita-Yamato Bank. The research area provides the important clue to the development of Miocene basins which are characterized by the normal faults and volcanic activities related to rifting in the continental crust. Kita-Yamato Bank is a small sediment-filled graben which was formed by failed rifting in the Early Miocene. The basins rapidly vary the bathymetry, depth of acoustic basement and thickness of sedimentary layer. The tension in the study area caused the extensional lithospheric deformation before/during the Early Miocene. In consequence, tectonic forces resulted in the depression or subsidence of basement from continental rifting in the Kita-Yamato Bank followed by the opening of the Ulleung Basin, and caused the onset of graben or half-graben structure bounded by large blocked syn-rift faults. Afterward no significant tectonic deformation exists, with the consequence that post-rift normal faults with small heave were formed and reactivated by the resultant forces such as tectonic subsidence, sediment loading and volcanic activity. The Cenozoic sediment layer has a maximum thickness of 1.0 s along the center of the graben or half-graben, which overlies the consolidated acoustic basement. Seismic units V and IV supposed to be syn-rift sedimentary rocks are deformed by both the volcanic activities and numerous basement-involved normal faults induced from extension. In the uppermost layer, slump scars resulted from the slope failure are recognized.

Seismic interpretation was carried out based on biostratigraphy of Fukue-1 well in Japan side of the Domi Basin and compared with the Cheju Basin and Tertiary basins in north-west Kyushu. East China Sea Basin including Domi Basin began to develope in the latest Cretaceous$\sim$Paleocene related to rifting. The basin was filled with a thick package of syn-rift sediments during Paleocene to Oligocene and was under post-rift stage effected by transtenssion during Miocene. Previous studies suggest that the basin had been mostly filled with Miocene formation (>3 km), but the Miocene formation is interpreted to be comparatively thin in this study. The thickness of the Miocene formation varies from tens of meters to hundreds of meters and become thicker to the south-west of Cheju Basin. The index taxa of the Oligocene$\sim$Eocene nannofossils and dinoflagellates found in the Cheju Basin and Tertiary basins in north-west Kyushu also corroborate the result of this study.

두가지 방법의 Tension Suture가 개에서 손상을 입은 피부의 접합에 평가되어졌다. 이들 술식은 Vertical Mattress Tension Suture와 'Walking'봉합이다. 7주후에 타원형으로 손상된 피부의 반흔조직을 추적하여 면적을 측정하였다. 흠손된 피부의 반흔조직의 평균 넓이는 V.M.T.S의 $5.29cm^2$에 비해 'Walking'봉합의 경우는 $2.07cm^2$였다. 이는 'Walking'봉합의 경우가 명백히 반흔조직이 좁다는 것이 관찰되었다. 더구나 어떤 손상의 경우더라도 'Walking'봉합은 열개(봉합한 자국)가 발견되지 아니했다.

Reflection seismic survey has been conducted using R/V Yuzmogeologia of Russia on the area of between northern part of Powell basin and South Scotia Ridge. 48-channel seismic data have been processed using Promax system. Hesperides and Eastern Deep located in the central part of the South Scotia Ridge show similar geological structure comprising two distinct sedimentary layers. The lower layer filled with fault breccia is considered to be formed with the expansion of the deeps. The upper layer is filled with pelagic sediments which implies this layer is formed after the spreading of the deeps has stopped. The south branch of the South Scotia Ridge is characterized by bigger width than the north branch. Topographical depression shown in the south branch is formed by many faults accompanied with the seafloor expansion of Powell basin.

The Korean Dendropanax lacquer, made from a natural resinous sap from Dendropanax orbifera Lev., was used as a golden and transparent varnish for the traditional artifacts (armor uits, helmets, arrowheads, etc.) to make them be brilliant golden color. The cured film of the acquer has excellent protective properties such as weatherability, water resistance, and nticorrosive. But, one of disadvantages is that takes a long time and much energy to fulfill curing the lacquer. The chemical constituents of the lacquer contained conjugated diene compounds s the photopolymerizable monomers. These monomers easily polymerized in sunlight to form olden-colored, hard-coating films in a short time. Photooxidation may be one of the most mportant reactions in the chemistry of the lacquer. Although the Korean Dendropanax Lacquer hould be dried to a thoroughly dry stage to achieve optimal film properties, curing with elevated emperatures may be required for the protracted curing time at atmospheric temperature. So we ntended to accelerate the curing rate of the lacquer by dual curing of thermal and radiation uring. The effect of thermal initiator on the thermal curing reaction was evaluated by monitoring he changes in double bond peak with FT-IR. Then the curing rate of the lacquer blended with hermal initiator and photoinitiator together was measured during dual curing using a RPT with V spot curing machine. Thermal initiator not only accelerated the curing rate but also improved he physical property. And the curing rate of the Korean Dendropanax lacquer was improved by ual curing method of thermal and UV curing. According to these results, the application area of he Korean Dendropanax lacquer could be expanded to surface coatings for electronic devices uch as mobile phones or electronics.

The study is to investiagte the transition of types of Deul-E-Yul-Gae(lift up) windows and doors in Korean traditional architecture which was on the wall batween Dar Chung and Bang. As the result of studying and analysizing the transition of those the following conclusion could be obtained. The first type was to attach windows on the middle of Deul-E-Yul-Gas(lift up) doors, the second type remove windows attached on that or be(Maeng-Jang-Jee) dark paper covered door annexed Bool-Bal-Gee, and the third type to be (Myung-Jang-Jee) bright paper covered door of bottom panel slender ribs which was the most openness. Finally, we could understand the transition which would be changed from the type of(Maeng-Jang-Jee) bright paper covered lift up door of bottom panel slender ribs that had a pliable and open mood.

The two-sample locally optimum rank detection scheme is obtained which uses rank and sign statistics for detection of random signals in additive noise. It is shown that the detector is similar in structure to the locally optimum detector for random signals and to the one-sample locally optimum rank detector for random signals. It is also shown that the detector is a generalization of the two-sample locally optimum rank detector for known signals. In addition , the problem of two-sample locally optimum rank detection of random signals in multiple input case is considered briefly.
