Purpose : The research was done to investigate the effectiveness of 2D bony morphometry and microstructure of micro-computed tomography (micro-CT) on the osteoporotic bony change. We performed the bone morphometric analysis of proximal femur in ovariectomized rabbits with BMD and micro-CT examination. Materials and Methods : Twenty-one female (Newzealand, about 16 weeks old, 2.9-3.4 kg) rabbits were used. Three rabbits were sacrificed on the day when experiment began (Baseline). The remaining 18 rabbits were divided into two groups. One group was ovariectomized bilaterally (OVX) and the other animals were subjected to sham operation (Sham). Bone specimens were obtained from the right and left femur of sacrificed rabbits. At intervals of 1, 2, 3, 5, 6 months respectively, BMD tests were performed on the proximal femur by using PIXImus 2 (GE Lunar Co. USA), 2-dimensional bone morphometric analysis by custome computer program and 2D/3D bone structure analysis by micro-CT (Skyscan1072, Antwerpen, Belgium). Statistical analysis was carried out for the correlation between bone morphometry , micro-CT and BMD Result : BV/TV, Tb.Th, Tb.N of micro-CT parameters showed higher values in sham group than OVX group. N.Nd/Ar.RI, N.NdNd, N.NdTm, N. TmTm, PmB/Ar.RI, 3-D BoxSlope of 2D morphometric parameters showed higher values in Sham group than OVX group. The micro-CT parameters of Tb.Sp, Tb.N were statistically significant correlated with BMD respectively. Several 2D morphometric parameters were statistically significant correlated with BMD respectively. Conclusion : Several parameters of 2D bony morphometry and micro-CT showed effective aspects on the osteoporotic bony change. (Korean J Oral Maxillofac Radiol 2007; 37 : 27-33)

Hepatobiliary cystadenoma is a rate but distinct neoplasm with malignant potential, similar to that occuring in the pancreas or ovary. The differential diagnosis of hepatobiliary cystadenoma includes other cystic neoplasms, primary and metastatic, and nonneoplastic cysts including infective conditions. A preoperative distinction from hydatid disease, difficult on radiologic grounds alone, is particulary important. We report a 38-year-old woman admitted because of intermittent epigastric pain. Abdominal ultrasonography, CT and MRI revealed about 15×10㎝ sized multiloculated cystic lesion in medial segment of left lobe of the liver. Hydatid serologic analysis was normal. But serum level of CA 19-9 was raised above 2400U/mL. Under ultrasonographic guidence, we performed aspiration of the cystic fluid. In the examination of cystic fluid, malignant cell was abscent and cystic fluid level of CA 19-9 was also rasied above 2400U/mL. Under the impression of hepatobiliary cystadenoma, laparotomy was performed. A 15×10㎝ sized cystic mass was noted in the medial segment of left lobe of the liver, and then left lobectomy was done. On cut section, 1800mL of serous fluid was obtained from the multiloculated cystic mass. Microscopic findings revealed a cystadenoma lined by a single layer of columnar epithelium containing some intracellular mucin pools and hemorrhagic infact without evidence of cellular atypism or mitosis.

The diffuse sclerosing variant (DSV) is a rare malignant tumour that accounts for 0.7-5.3% of all papillary thyroid cancers. DSV tends to occur at a younger age and has a higher incidence of cervical lymph node metastases, compared with papillary thyroid carcinoma. A 62-year-old female patient diagnosed thyroid nodule with diffuse and mild increased 18F-deoxy-glucose (FDG) on FDG positron emission tomography (PET)-computed tomogram (CT) scan. The ultrasound images showed typical findings of DSV such as diffusely enlarged thyroid lobes and diffusely scattered microcalcification. We performed this patient ultrasonography guided fine needle aspiration and cytologic analysis revealed papillary carcinoma. Total thyroidectomy with central compartment node dissection and lateral lymph node dissection was performed and finally diagnosed DVS. The authors report this case with literature review.

조경블럭을 이용한 환경친화적 보강토옹벽의 시공사례연구

한중근,송영석 중앙대학교 기술과학연구소 2003 기술과학연구소 논문집 Vol.33 No.-

블록식옹벽은 다양한 토목 및 건축공사에서 적용되고 있으나, 옹벽시공시 환경친화적 요소의 유무가 점 차 문제화 되면서 공공공사에서는 특히 설계요소로서 인간생활과 친밀해질 수 있는 특징으로 친환경적 요소가 필요하게 되었다. 이러한 관점에 주안을 두고 친환경적 요소를 갖는, 즉 식생이 가능한 보강토블록으로서 그린스톤이 개발되었다. 그린스톤블록은 조경용 블록으로서 도심지등에서 많이 적용되며, 식생 조건에 맞는 자동화된 배수체계를 도입하였다. 그러나, 그린스톤은 직립옹벽의 형상으로 제한된 높이와 국부파괴의 위험이 상존함을 시공사례 고찰을 통해 확인하였다. 이를 만족하기 위해, 뒤처짐경사를 갖는 친환경적 블록으로서 중력식블록세트(그린스톤플로, 연결축 및 고정축)가 개발되었고 개발된 시스템의 시공사례를 이용하여 문제점을 고찰하여 시공 및 설계기준을 마련하였다. 중력식블록옹벽의 설계 및 시공시 주의할 점은 부등침하의 원인이 되는 기초지반의 지지력, 옹벽배면에서의 배수무네가 가장 큰 문제이었으므로 본 연구에서는 블록식옹벽 시공시 적합한 관리 및 설계기준으로 기하수위, 기초지지력 및 배수조건에 대하여 제시하였다. 특히, 도심지내에서는 친환경적요소의 특징이 더욱 발휘될 수 있음을 확인할 수 있었다. The SRW(segmental retaining wall) including soil-reinforcement retaining wall has been used for various construction works in Civil and Architectures works. But the non-environmental factors in this system are one of significant problems. Then, the environmental factors within familiarity in field were become to the design factor in the public works. The Green Stone was developed. which can be planting and can be make a possible to construction of closed environmental structures. This landscape block can be automatically management of lowers and plants at spaces between blocks in all seasons using the drop water system. The existing systems have got usually the possibility of local failure. Through case studies, the shapes of block were improved to gravity Green Stone FLO. That is composed to three parts as follows; Green Stone FLO, Trunk-Bar and Anchor-Joint. This system was satisfied for the problem of structure stability with setback. The significantly considering problems at design and construction of soil-reinforcement retaining wall are he bearing capacity of foundation to the control of non-uniformed settlement and drainage system in retaining wall backside. In study, therefore, the design criteria and its control conditions were suggested to on the groundwater level, foundation bearing capacity and drainage conditions. The feature of gravity block including environmental factors could be defined, especially, the advantages of improved block appeared and shown in downtown.

Cerebral angiography has been essential for the diagnosis of the intracranial aneurysms but. is sometimes accompanied by serious complications. Resolution of CT angiography was up-graded greatly to represent the three-demensional structure of vesseles since helical CT had been introduced. We have compared 26 cases of CT angiography and 28 cases of conventional angiography in terms of specificity and sensitivity for the diagnosis detectable aneurysm diameter. configurational diagnosis and diagnostic confidency. All results showed no statistical difference between CT angiography and conventional angiography. These should suggest that CT angiography could be replaced with conventional angiography for the diagnosis of ruptured aneurysms and even of unruptured aneurysms. resulting in the introduction of first screening modality of unruptured aneurysms.

지연성근육통에 대한 수지요법의 효과

송영래,정한영 한국학교체육학회 2001 한국학교 체육학회지 Vol.11 No.2

지연성 근육통에 대한 예방과 치료법은 다양하다. 그러나 아직까지 명확한 치료법은 밝혀지지 않았다. 따라서 본 연구는 수지요법이 지연성 근육통에 대한 예방과 치료법의 대안으로 적합한지를 보기 위하여 수지요법을 이용한 통증역치의 변화를 알아보았다. 실험에 참가한 대상자는 5대학교에 재학중인 건강한 여학생 18명으로 실험군과 대조군에 9명씩 무작위 배치하였다. 지연성 근육통은 슬관절 굴곡근과 신전근에 등속성 운동을 시행하여 유발하였으며, 통증역치의 수치는 지연성 근육통을 유발하기 전과 후, 그리고 치료 후 각각 3회 측정되었다. 실험군에서는 30분의 수지요법 치료과정을 거쳤 고 대조군은 치료과정이 없었다. 연구의 결과 실험군에서 치료 후의 통증역치는 치료전에 비해서 상승하였으며 통계학적으로 유의한 차이가 있었다(p<.05). 대조군은 치료 전·후에 유의한 차이가 없었다(p<.05). 치료 전·후의 실험군과 대조군의 통증역치의 변화량을 비교한 결과 실험군의 통증역치의 변화량이 대조군보다 유의하게 높았다(p<.05). 이상과 같은 결과로 지인성 근육통에 대한 수지요법의 적용은 효과적이라 할 수 있으며, 앞으로의 연구는 그 기전에 대하여 다루어져야 할 것이다. There are diverse prevention and treatment methods for Delayed Onset Muscle Soreness(DOMS). There are, however, controversy regarding effective treatment methods. Therefore, the purposes of this study were 1) to determine the changes between pre and post-treatment of two groups of 18 people and 2) to examine the effect of Koryo Hand Therapy on pressure threshold. DOMS was induced when isometric exercise were performed the flexor muscle and extensor muscle of knee joint. Eighteen healthy subjects (female=18) aged 20 to 23 years were randomly assigned to one of two troups. Group 1 received Koryo Hand Therapy to the appropriate hand points for DOMS of knee flexor muscle. Group 2 received no treatment and served as control. Pain threshold at the knee joint. Determined by a painful Apbong before and 30minutes after hand stimulation. Experimenta3 group was the only group that showed statistically significant increase(p <.05) in pain threshold. These results suggest that Koryo Hand Therapy has the capability to increase pain threshold.
