For the purposes of augmentation of the aid for case analysis and diagnosis of malocclusion, a roentgenocephalometric study was made form 84 Korean adolescences. The Subjects consist of 42 males and 42 females aged from 17 to 20 years with normal occlusion and acceptable facial appearance. The author measured 18 angles and 14 linear distances as suggested by Jarabak. The following results were obtained. 1) Each linear measurement of the males' skull was greaten than that of the females. 2) The posterior to anterior facial height was 69.2% in the males and 67.1% in the females. 3) In the relationship of upper lip to esthetic line, the lip of females was more behind than that of males. 4) Saddle angle was 124.7。, articular angle was 148.7。, gonial angle was 119.4。 and upper and lower gonial angles were 45.1。(N-Go-a。) and 74.2。(N-Go-Me。). 5) The ratio of mandibular body to anterior cranial base was about 1:1.1. 6) The angulations of SNA。, SNB。 and SNP。 were as follows; SNA。, 80.3。, SNB。, 79.8。, SNP。, 81.1。. 7) The angle of the sella-nasion plane to the mandibular plane (SNG。Me。) was 32.0。 and that of the occlusal plane to the mandibular plane was 18.2。. 8) The angle of the maxillary central incisor to the sellanasion plane (1-SN。) was 105.6。. That of the mandibular central incisor to the mandibular plane (1-GoMe。) was 94.0。, and the interincisal angle (1 to 1。) was 127.6。. 9) The linear distance from incisal edge of upper central incisor to facial plane was 8.0mm and that of lower central incisor was 4.6mm. 10) In the relationship of the lower lip to the esthetic line, the lower lip was 0.2mm front of the esthetic line.

충북 영동 영국사 대웅전 하부 토양층에서 출토된 탄화 목재의 현장 보존처리 방법을 개발하고자 하고자, 6가지 처리법을 실험한 결과 PEG#400 10%를 4일간 1일 1회씩 점적(dropping)한 후 PEG#4000 10%에서 40%까지 단계적으로 점적하는 방법이 좋은 치수안정성을 나타냈으며, 육안적으로 관찰했을 때도 갈라짐이 발생하지 않고 견고하였다. 이 방법을 건물 하부에서 출토된 주두로 보이는 탄화 건축부재 2점에 대해 현장에서 경화처리를 실시하였다. 현장에서의 시간 제약상 PEG#400 10%로 점적한 후 바로 PEG#4000 80%를 로 가열하여 다시 점적하였다. 경화 처리된 주두는 실험실로 운반하여 PEG#4000 80%()로 재처리한 결과 우수한 치수안정성을 보여주었다. The conservation methods for the charred-woods excavated under the Daewoongjeon Hall of Youngguksa Temple, Youngdong, Chungbuk, Korea were investigated. The tests revealed that PEG#400 10% for four days followed by gradual application of PEG#4000 10% to 40% showed the most stable and robust results, showing no cracks in macroscopic examination. This treatment method was applied to the two charred elements, which appeared to be the capitals at the excavated site. After the treatment, the consolidated capitals were transported to the laboratory, where they were retreated with PEG#4000 80% at .... Charred capitals showed also an excellent level of stability.

Seonreung is the tomb of Seong-jong (A.D. 1457~1494), the 9th king of Joseon Dynasty (1392-1910) and his second queen Jeonghyeon-wanghu (1462~1530). We obtained dendrochronological dates of Jeongjagak (ceremonial hall) of Seonreung. It was known first built in 1495 and reconstructed in October 1706, We obtained tree-ring dates of 20 wood elements (beams, pillars, truss posts, cant strips, roof boards and roof loaders). Their outermost rings were dated from 1630 to 1705. The dates of bark rings in four elements were A.D. 1705 with completed latewoods, indicating that these woods were cut some time between the autumn of 1705 and spring of 1706. The results confirmed the reconstruction date Jeongjagak of Seonreung in 1706, suggesting that there was not so long period for wood drying or storage, i.e., less than 6 months. The dates of outermost rings prior to 1705 in other elements indicated that some outer rings of these elements were removed during wood processing. Tree-ring dating proved that the present Jeongjagak of Seonreung had been well preserved for more than 300 years.

In order to screen new allogeneic mixed lymphocyte culture (allo-MLR) inhibitor which is expected to be immunomodulating drug lead, we have investigated allo-MLR inhibitory activity on the marine-derived symbiotic microorganisms (1,895 strains) from the marine algae. The potent inhibitory activities (over 45% inhibition of proliferation at 10 and 2 µg/ml)without cytotoxicity were observed in the extracts of 46 strains. While, the significant stimulating activities (over 100% proliferation at 10 and 2 µg/ml) without cytotoxicity were observed in the extracts of 5 strains. In the second assay using 46 bioactive strains, 14 strains exhibited again significant allo-MLR inhibitory activity. Finally, 11 strains among the 14 strains inhibited proliferation and IFN-γ production of CD4+ T cells during the stimulation with specific antigen in the third assay. On the basis of above results, the marine algae is nice source for isolation of immunomodulating microorganism, and the marine algae-associated microorganism is also nice target for development of the new immunomodulating drug lead.
