The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

윤일혜,김현주,이상호 대한건축학회 2003 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.23 No.1(계획계)

Commercial building of small-medium scales in korea are being developed by multiple aspects. Commercial building of small-medium scales are lacking in representation of commercial function and characteristic image of their own. Therefore, the representation of commercial function is substitutes by many billboards and signboards and the visual street environment has been going from bad to worse. Planning of exterior renovation must include the representation of commercial function and the representation must be formed by architectural methods. Representation of commercial buildings means that communicational function of architectural and identity of architecture. The result of this study are as follows. The methods of Double skin and hybrid of surface and using new material on surface and wall is effective and economical methods to increase the representation of commercial function.

윤희훈,이상대,김영재,장기택,한세현,이상훈 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.2

Lymphangioma는 림프관에 나타나는 양성종양으로 림프관의 증식을 특징으로 한다. 이 종양의 대부분은 출생 시에 나타나며 종양의 95%정도가 10세 이전에 나타난다. 구강 내에 발생하는 경우에는 혀에서 가장 호발하며 거설증을 야기한다. 대개 양측성으로 혀의 전방 2/3부위에 나타나며 불규칙한 회색과 핑크빛을 띤 소절형태를 보인다. 본 증례 모두에서 환아들은 출생당시 혀에 lymphangioma를 지니고 태어나 거설증을 보였으며 이로 인해 개교합과 하악과성장 양상을 나타내었다. Lymphangioma에 의한 비정상적인 혀의 비대에 의해 환아의 구강과 두개안면부의 주위조직에 대한 적응 결과로 나타난 소견을 관찰하고 관련문헌을 고찰하여 다소의 지견을 얻었기에 보고하는 바이다. Lymphangioma is a benign tumor of lymphatic vessels. The majority of cases are present at birth and 95% of the tumors aroused before the age of 10 years. Oral lymphangioma may occur at various sites but are most frequent on the anterior two thirds of the tongue, where they often result in macroglossia. The lesions present nodularity with gray and pink projections. In the present cases, all the patients who had the macroglossia combined with lymphangioma showed openbite and mandibular prognathism. The purpose of this paper was to report the dental and craniofacial findings of macroglossia combined with lymphangioma and review the pertinent literature through the cases.

The high coherence of laser beam has made it possible to observe interference effects even in the light scattered from rough surfaces. That's why, when object with a scattering surface is illuminated with laser light, we do see a speckled appearance due to random interference. This sort of unique property of laser speckle has brought into existence the new noncontacting techniques such as speckle metrology method of measuring deformation, displacement, and vibration etc of objects with high optical sensitivity. The measurable range of speckle metrology especially used to measure in-plane information, however, is limited by some factors, the so-called strain, rotation, tilt of surface and out of displacement perpendicular to the plane of analysis. This restrictions severly limits the measurable range of speckle metrology by causing the decorrelation of speckle patterns. It is the purpose of this paper to give a survey on the measurable limitation of speckle photography method that is one of speckle metrology. Namely we will discuss the mutual relationships and problems of each limitations adding the restriction of the largest and smallest displacement measurable with speckle methods.

There are many causes of trismus. Aetiology can be roughly divided into muscle spasm, mechanical interference, extracapsular ankylosis, intracapsular ankylosis. Trismus caused by mechanical interference between postero-lateral wall of zygoma-maxillary complex and coronoid process following reduction of fractured facial bone is rare. Especially on maxillary bone fracture, when we faced the trismus following removal of intermaxillary fixation, we got used to solve that problem by physical exercise, We obtained good resurts by coronoidectomy on patients with limited mouth opening who were referred from department of plastic surgery, St. Marys' hospital, the Catholic university of Korea. We report our experience with literature review.

하악전돌증의 악교정수술 후 연조직 형태변화에 대한 연구

성상진,박현도,김재승,문윤식 대한치과교정학회 2000 대한치과교정학회지 Vol.30 No.3

악교정수술에 관한 치료계획은 치료결과에 관한 정확한 예측을 바탕으로 수립되는 것이 바람직하며 이는 심미적인 결과를 얻기 위한 가장 중요한 요소 중에 하나이다. 성인에서 골격성 하악전돌증의 치료는 하악골후퇴술을 이용한 악교정수술법이 주로 이용되는데, 술후 턱끝의 돌출도가 과도하게 감소되어 하악전진이부성형술을 추가로 시행해야 하는 경우 하악골과 턱 부위의 연조직 변화방향이 상이하게 나타나므로 술후 연조직 변화를 정확히 예측하는데 한계가 있다. 본 연구에서는 골격성 하악전돌증을 주소로 악교정수술을 시행한 성인을 대상으로, 상행지시상분할골절단술(BSSRO)만을 시행한 경우(A군) 11명과 하악전진이부성형술(advancement genioplasty)도 같이 시행한 경우(B군) 9명의 경조직과 연조직 변화의 상관관계를 알아보기 위하여, 수술 8개월 이후에 채득된 측모두부계측방사선사진을 비교하여 다음과 같은 결과를 얻었다. 1. E-line에 대하여 상순은 더 돌출되고 하순은 더 후퇴되어 입술의 형태가 개선되었으며,하악전진이부성형술을 병행한 경우 하순의 돌출도는 더 개선되었다. 2. 두 군 모두에서 상순은 후방이동하고 비순각은 증가하였다. 3. 술후 B점에 대한 연조직 POGs점의 변화율은 A군에서 84%, B군에서 66%로 나타났으며 두 군간에 통계적 유의성이 있었다. 4. 경조직과 계측점의 수직변화량은 A군에서 감소하였다. The treatment plan for orthognathic surgery must be based on accurate predictions, and this can be produced the most esthetic results. Treatment of prognathic mandible in adult is usually orthognathic surgery using mandible set back, but mandible with retruded chin point is needed additional chin augmentation. In this case, the directions between mandible and chin point are different therefore, the prediction of soft tissue reactions must be modified. In this study, we materialize the patients who was taken orthognathic surgery due to prognathic mandible, 11each(Group A) was taken only Bilateral Sagittal Sprit Ramus Osteotomy (BSSRO), 9each(Group B) was taken additional advancement genioplasty. The lateral cephalometric radiography taken 8 months later after orthognathic surgery by this patients were used. The results of this study were as follows : 1.The profile of lips was favorable after surgery due to upper lip to E-line became prominent and lower lip to E-line was retruded. 2.In both group, upper lip moved posteriorly and nasolabial angle was increased. 3.The ratio of the soft tissue profile change in POGs point to skeletal B point movement was 84% in group A and 66% in group B, and there was statistical significance between group A and group B. 4.Vertical movement of hard tissue points is decreased in group A.
