평안누층군의 재조명: 송림 조산운동의 변성작용과 변형작용

김형수,Kim, Hyeong Soo 대한자원환경지질학회 2019 자원환경지질 Vol.52 No.5

태백산분지에 분포하는 평안누층군은 고생대 말-중생대 초기 동안 한반도 형성에 영향을 미친 송림 조산운동의 지구조적 특성을 이해하는데 필요한 지질학적 증거들을 가지고 있다. 따라서 이번 논문은 기존에 발표된 평안누층군의 변성-변형작용과 쇄설성 저어콘의 연령측정 결과들을 바탕으로 송림 조산운동의 특성을 알아보고, 평안누층군의 지질학적 중요성과 연구 필요성에 대해 고찰해 보고자 한다. 평안누층군의 쇄설성 저어콘의 Th/U 비와 연령분포 결과는 고생대 말 태백산분지의 퇴적환경은 능동적 대륙연변부의 화산호 형성으로 인해 만들어진 대륙전호분지와 후호 대륙전면분지일 것으로 판단된다. 또한 주된 화성활동은 펜실베니안 초기와 페름기 중기에 발생하였고, 따라서 평안누층군의 퇴적작용과 화성활동은 거의 동시기에 발생하였다. 송림 조산운동 동안 평안누층군은 저온-중압(M1)과 중온-중압(M2)의 광역변성작용에 영향을 받았다. M1 동안 경녹니석, 홍주석, 남정석 반성변정을 함유한 점판암과 천매암은 동-서 방향의 압축작용과 함께 수반된 습곡/전단운동에 의해 심하게 변형되어 산출되며, M2와 함께 수반된 남-북 방향의 최대 압축작용 동안 석류석과 십자석이 반상변정으로 형성되었다. 이런 평안누층군의 변성작용은 약 220-270 Ma 동안에 변형작용이 집중되는 지역에서 발생한 것으로 해석된다. 향후 고생대 태백산분지의 진화와 송림 조산운동의 지구조적 특성을 규명하기 위해서 평안누층군에 발달한 변성대의 광역적인 분포와 지질구조들의 특성과 형성 시기 그리고 고생대 말 태백산분지의 고지리 위치 등과 같은 연구가 수행되기를 기대한다. Pyeongan Supergroup (PS) in the Taebaeksan basin preserves key geological evidences to understand the tectonometamorphic evolution of the Songrim orogeny that affected the formation of the Korean Peninsula during the late Paleozoic to early Mesozoic. The aims of this paper therefore are to investigate the characteristics of the Songrim orogeny based on the previous results of metamorphism and deformations of the PS, and then to review geological significance and research necessity of the PS. Age distributions and Th/U ratio of detrital zircon in the PS indicate that sedimentary environment of the Taebaeksan basin during the late Paleozoic was arc-related foreland basin and retro-arc foreland basin at the active continental margin. In addition, the main magmatic activities occurred in the early Pennsylvanian and Middle Permian, thus sedimentation and magmatic activities occurred simultaneously. The PS was affected by lower temperature-medium pressure (M1) and medium temperature and pressure (M2) regional metamorphism during the Songrim orogeny. During M1, slate and phyllite containing chloritoid, andalusite, kyanite porphyroblasts intensively deformed by E-W bulk crustal shortening combined with folding and shearing. And garnet and staurolite porphyroblasts were formed during the N-S bulk crustal shortening accompained by M2. Such regional metamorphism of the PS is interpreted to occur in an area where high strain zone is localized during ca. 220-270 Ma. In order to elucidate the evolution of the Taebaeksan basin and tectonic features of the Songrim orogeny, it is expected that the study will be carried out such as the regional distribution of metamorphic zones developed in the PS, characteristics and timing of deformations, and late Paleozoic paleo-geography of the Taebaeksan basin.

정복 불가능한 슬관절 탈구의 드문 예: 내측광근의 단추구멍손상 - 증례 보고 -

정복되지 않는 슬관절 탈구 중 내측 광근에 의한 단추구멍 손상에 의한 경우는 매우 드문 경우로 이에 대한 신속한 정복이 지연된 슬관절 탈구로 발생할 수 있는 합병증을 줄일 수 있다. 저자들은 슬부의 후외방 전위와 대퇴골 내과의 돌출을 보이는 환자를 자기 공명 영상으로 진단하고 이에 대해 관절 절개술을 이용하여 정복술 및 양측 십자인대 복원술로 치료한 환자를 경험하였다. 술후 10개월에 환자는 경도의 후방 불안정이 있었으나 관절의 운동 범위는 정상으로 회복되었다. The muscular button holing of vastus medialis is a very rare case of irreducible knee dislocations, and rapid reduction of this can diminish the complications which delayed reduction accompanies. We diagnosed a patient who appeared posterolateral dislocation of the knee and protrusion of the medial femoral condyle with MRI grossly. That was reduced by open arthrotomy, followed the reconstruction of both cruciate ligaments and repair of medial collateral ligament. Patient didn't show joint instability except minor posterior sagging and had full range of motion postoperatively after 10 months.

김형수,양홍서,Kim, Hyeong-Soo,Yang, Hong-So 대한치과보철학회 1997 대한치과보철학회지 Vol.35 No.1

Dental implant may be immediately placed in postextraction socket which has alveolar bone defect. The purpose of this study was to compare the bone regeneration and bone quality around defects adjacent to implants that were placed into extraction sockets according to EFEB, GTAM barrier and GTAM barrier with DFDB. Mandibular P2, P3 and P4 were extracted bilaterally in dogs, and buccal defects were created about 4mm in depth and 3.3mm in width. Screwed pure titanium implants, 3.8mm in diameter and 10mm in length, were placed into the extraction sockets. The experimental groups were divided into four groups : the G group was covered with a GTAM barrier on the defective area, the D+G group was filled with DFEB and covered with a GTAM barrier, the D group was filled with DFDB only and the control group was sutured without any special treatment on the defective area. The experimental animals were killed after 12 weeks and specimens were prepared for light microscopic evaluation and fluorescent dyes were administered daily for 2 weeks after implantation, and injected on the 4th and 11th week for fluorescent microscopic examination to observe new bone formation and bone remodeling. The new Bone height of the buccal defect was measured and compared with the another for bone gain and the removal torque for the implant was measured for the comparison of bone density and bone-implant osseointegration. Results obtained were as follows : 1. Experimental groups showed bone regeneration in oder from D+G, G, D group and control. D+G and G group was significantly from D group and control(P<0.01). 2. In the defective area of control the regenerated alveolar bone showed poorly developed lamellated structure and fibrous tissue intervention into the bone-implant interface but the others showed well developed lamellated structure and osseointegration. 3. All implant groups showed no significaant difference in the removal torque for implant(P>0.05) These results suggest that immediate implants placed in defective sockets were successfully osseointegrated and utilizing placed in defective sockets were successfully osseointegrated and utilizing not only the combination of GTAM and DFDB but also only the GTAM was favorable for the predictable regeneration of the defective area.

4겹의 반건양건과 골-슬개건-골을 이용한 관절경적 전방 십자 인대 재건술의 중기적 치료 결과 비교

김형수,박승림,강준순,이우형,김기욱,Kim, Hyoung-Soo,Park, Seung-Rim,Kang, Joon-Soon,Lee, Woo-Hyeong,Kim, Ki-Wook 대한관절경학회 2001 대한관절경학회지 Vol.5 No.1

목적 : 본 논문의 목적은 전방 십자 인대 손상에 있어서 반건양건과 골-슬개건-골 자가이식을 이용한 관절경적 전방 십자 인대 재건술후의 술 후 중기적 성공여부와 안정성을 비교하기 위함이다. 대상 및 방법 : 순수한 전방 십자 인대 파열만을 가진 80명의 환자를 대상으로 하였다. 평균 추시 기간은 골-슬개건-골군은 49.4개월이었고 반건양건군은 48.8개월이었다. 술후 주관적인 Lysholm score와 anterior drawer test, Lachman test, pivot shift test, KT-2000 measurement에 따른 객관적인 이완정도 및 IKDC 평가법을 이용하여 최종결과를 비교하였다. 결과 : 전방 전위 검사상 반건양건군에선 양성이 $22.5\%$, 골-슬개건-골군에 $27.5\%$ Lachman 검사상 반건양건군에선 양성이 $30.0\%$, 골-슬개건-골군에선 $25.0\%$, pivot shift 검사상 반건양건군에선 양성이 $15\%$, 골-슬개건-골군에선 $20\%$를 보였으며 통계학적으로 의미있는 차이를 보이지는 않았다(p>0.05). 20lbs에 따른 KT-2000 검사의 차이는 반건양건군에서는 2.2mm, 골-슬개건-골군에서는 2.1mm의 차이를 보였다(p>0.05). 주관적인 Lysholm 점수 평가 상 두군에서 의미있는 차이를 발견하지 못하였다(>0.05). 전방 슬관절의 통증은 골-슬개건-골군에서 더 흔히 나타났으며 양쪽군 모두가 IKDC 등급 상 $82.5\%$에서 유사 정상 등급 이상의 결과를 나타내었다. 결론 : 전방 십자 인대 재건술에 있어서 골-슬개건-골이식건을 이용하는 방법과 비교하여 반건양건도 관절의 안정성에 있어서 유용한 방법으로 생각된다. Purpose : The purpose of this study was to compare the postoperative success and stability of arthroscopically assisted anterior cruciate ligament(ACL) reconstructions using central one third bone-patellar-tendon bone(BPB) autograft versus quadrupled semitendinos-us(ST) autograft as the medium term review. Materials and Methods : Eighty patients(40 BPBs,40 STs) with isolated ACL injury were available for a mean follow up of 49.4 months(BPB) and 48.8 months(ST). There was no significant difference between the two groups with respect to age and sex. We compare the final results between two groups with respect to subjective Lysholm score, objective laxity including anterior drawer test, Lachman test, pivot shift test, KT-2000 measurements and International Knee Documentation Committee(IKDC) evaluation system. Results : Postoperatively, positive anterior drawer test was found in $22.5\%\;and\;27.5\%$, positive Lachman test was found in $30.0\%$ and $25.0\%$ and positive pivot shift test was found in $15\%\;and\;20\%$ of the ST and BPB group, respectively(p>0.05). Mean side to side difference of KT-2000 at 20 lbs was 2.2 mm for the ST group and 2.1 mm for the BPB group. There was no significant difference between the two groups about Lysholm score(>0.05). Anterior knee pain was knee common in the BPB group. Eighty-three percent of the patients were nearly normal according to the IKDC grade in both groups. Conclusion : We consider that autogenous semitendinosus tendon is a good alternative subsititute in ACL reconstruction together with the bone-patellar tendon-bone autograft.

2차유동이 평판후류의 난류구조에 미치는 영향

The effects of secondary flow on the structure of a turbulent wake generated by a flat plate was investigated experimentally. The secondary flow was induced In a $90^{\circ}$ curved duct in which the flat plate wake generator was installed. The wake generator was installed in such a way that the wake velocity gradient exists in the span wise direction of the curved duct. Measurements were made in the plane containing the mean radius of curvature where pressure gradient and curvature effects were small compared with the secondary flow effect. All six components of the Reynolds stresses were measured in the curved duct. Turbulence intensities in the curved wake are higher than those in the straight wake due to an increase of the turbulent kinetic energy production by the secondary flow. In the inner wake region, shear stress and strain in the plane containing the velocity gradient of the wake show opposite signs with respect to each other, so that eddy viscosity Is negative in this region. This indicates that gradient-diffusion type turbulence models are not appropriate to simulate this type of flow.

우리 사회가 `다문화 사회(multi-cultural society)`로 이행해 감에 따라 파생되는 다양한 문제에 대한 대책이 필요한 시점이다. 2006년 참여정부의 다문화정책을 시발로 다문화에 관련된 다양한 정책이 논의되고 있다. 하지만 전통적인 관료제에 의한 접근방식으로는 다양한 정책적 이슈들을 통합하고 관리하는 것은 어려운 실정이다. 따라서 복잡다기한 다문화정책의 실효성을 확보하기 위해서는 공공부분의 네트워크 구축을 통한 효과적인 지원방안을 강구하는 노력이 필요하다. 이에 본 연구는 각 부처별로 진행되고 있는 정부 차원의 다문화 정책을 살펴보고 그 문제점을 지적하여 부처 간의 연계방안에 관한 정책적 함의를 구하는 것이 목적이다. 이러한 연구는 향후 다문화사회로의 이행과정에서 야기되는 문제점들을 최소화하는 정책적 기여를 할 수 있을 것으로 본다. The trend toward multi-cultural society has been rapidly grown in many aspects. Nevertheless, the tendency of globalization are ubiquitous and sweep almost every corner of the world. However, the governmental efforts to make good combinations with the foreign culture have been rare that create some of the contradictions. The United Nation has recommended Korea having an inclusive attitude toward foreigners and the foreign cultures. To be a global leader, it is necessary for the Korean to generate multi-cultural societies by absorbing not only foreign labors, but also the foreign cultures. In this perspective, this paper have dealt with some of the issues of multi- cultural society. The Korean government should play a pivotal role in building a global community by establishing the network systems with other cultures. This paper suggest some ways of improving the globalization by structuring the multicultural policy communities. The establishing multi-cultural policy network means obviously making linkages with other cultures. This trend would, we hope, lead us to realization of a global leader in the very near future.
