Cleidocranial dysplasia (previously known as cleidocranial dysostosis) is a well-known, rare and hereditary skeletal disorder characterized by a variety of dental abnormalities and as its name implies, striking involvement of the cra-nial vaults and clavicles. A 17-year-old female who presented with short stature and prolonged retention of decid-uous teeth, subsequent delay in eruption of permanent teeth is described, She could touch her shoulders together at the midline anteriorly. Diagnostic procedures showed hypoplasia of the maxillary and zygomatic bones, open fontanelles and sutures, and aphasia of the clavicles. The paranasal sinuses were absent or underdeveloped. Characteristically, she had near parallel-sided borders in the ascending ramus of the mandible and abnormal-shaped, the slender pointed coronoid process. The zygomatic arches had a downward bend and discontinuity at the zygomaticotemporal suture area. Radiographic and clinical investigations of her cranial and skeletal abnormalities revealed features of cleidocranial dysplasia.(Korean J Oral maxilloface Radiol 2000; 30: 229-234)

주정화,이기찬,이훈갑,노순성 대한신경외과학회 1979 Journal of Korean neurosurgical society Vol.8 No.1

We have recently experienced a case of malignant schwannoma in the right ulnar nerve. A 17 years old male underwent a surgery with a total removal of maligment schwannoma of the right ulnar nerve in the elbow. The tumor mass was walnut size with infiltration to the adjacent structures. The pathological findings show the pattern of interlacing bundles of long spindle cells, plumper hypochromatic elongatd or serpentile and eosinophilic nuclei with process and frequent mitosis, loss of cellular polarity and polymorphism can be seen. Pathological diagnosis was malignant schwannoma. Approximately 4 months later his innitial operation, the tumor recurred at right elbow and exillary region and removed without any proper treatment.

4-Aminosalicylic acid 유도체의 합성연구 : 2-Ethoxy-4-acetamidobenzthioamide 및 2-Methoxy-4-acetamidobenzthioamide의 합성 Synthesis of 2-Ethoxy-4-acetamidobenzthioamide, 2-Methoxy-4-acetamidobenzthioamide

2-Alkoxy-4-acetamidobenzthioamide was synthesized by reaction of hydrogen sulfide with 2-alkoxy-4-acetamidobenzonitrile which was dehydrated from 2-alkoxy-4-acetamidobenzamide by thionyl chloride or phosphorus pentoxide. 2-Alkoxy-4-acetamidobenzthioamide was obtained by hydrolysis of 2-Alkoxy-4-acetamidobenzthioamide with 10% hydrochloric acid solution.

상박신경총에 발생한 Granular Cell Myoblastoma 1예 보고

조순구,이기찬,이훈갑,주정화 대한신경외과학회 1980 Journal of Korean neurosurgical society Vol.9 No.2

Granular cell myoblastoma is an uncommon tumor occurring on the skin as a single nodule. The tumor are generally small, the usual size being 0.5 to 2cm in diameter. Its rate of growth is usually slow. It is found in nearly equal distribution in men and women and is most common in the third to fifth decade of life. This is a case report of a 37-year-old woman with solitary nodular mass on right brachial plexus. The histopathology of the lesion revealed the pale cytoplasm filling with characteristic granules. Nerve bundles are often seen among or adjacent to the tumor cells. The histogenesis of this tumor is still disputed but the most accepted theory today is the neural derivation. The treatment of choice is surgical excision.

The ranula is a form of mucocele which specifically occurs in the floor of the mouth. The ranula is classfied into simple ranula and plunging ranula according to the mechanism of development such as the salivary duct obstruction or the extravasation. Clinically this lesion develops as a slowly enlarging painless, fluctuant mass on one side of the floor of the mouth and the mucosa may have a translucent bluish color. An 8-month-old male infant visited our hospital with the chief complaint of the left submandibular swelling and the mass on the floor of the mouth. We tentatively diagnosed a simple ranula. The marsupialization was performed but the sign and the symptom did not subside, so we took the MRI. By the MRI we diagnosed a plunging ranula and excised the sublingual gland via the intraoral approach. The correct diagnosis is essential for the most effective treatment, which is the excision of the sublingual gland.

The main purpose of this study is to verify the structural validity of the questionnaire for the Self Management. Exploratory factor analysis is for the member of Female Soccer Players. In all 291 persons women For meddle school players 83, high school payers 78, senior players 130. The Self Manaement inventory, for the validation of factor structure we used the analysis of questions, of technical(frequency, averag, standard deviation, skewness, kurtosis, etc.). The result of elgenvalue is 6.36-1.24, total variance is 54.66%, The correlation of Self Management factors is .55-.41. The Cronbach'a of each factor is .83-.69. With confirmatory factor analysis is GFI=.91, CFI=.93, TLI=.92, RMSER=.05. The factors correlation is .71-.52, .66-.22 the varience of measurement error as .66-.22 express variance estimates sub-scale. In conclusion, The Self Management inventory of 4 factors 19 questions of validation is reasonable with approval level. Group differences between athletes and non-athletes on the selected subscales related to athletic capacity further supported validity of the Korean Female Soccer Players Self Management version.

기능성 담체를 이용한 질소·인 제거기술

백순기,정희정,이정환 동신대학교 환경연구소 2004 환경연구 Vol.9 No.1

국내의 폐수처리공정들은 호기성 처리이므로 유기물제거는 효율적으로 처리되어 왔으나 호소 및 하천 등의 부영양화를 일으키는 질소와 인이 제대로 처리되지 못하고 방류되고 잇는 실정이다. 본 연구에서는 A2/O 변형공법 및 담체 이용 폐수처리공법에 적용시키기 위한 질소·인 제거용 실험설비를 설계 제작하였으며, 이 실험 장치를 이용하여 처리방법별 수질오염물질 제거효율을 살펴보았다. 담체를 이용하지 않은 A₂/O변형공법의 경우, 수질오염물질의 제거효율을 T-N 94%,T-P 91.15%의 제거효율을 나타내었다. 담체로는 기능성담체, 흡착담체, 그리고 다공성담체를 사용하였는데, 기능성담체의 처리효율이 T-N 97%, T-P 94.75%로서 가장 높은 것으로 밝혀졌다. 또, 담체들을 혼합하여 처리효율을 살펴본 결과, 처리효율은 T-N 98.5%, T-P 96.19%로서 담체들을 각각 사용하는 경우보다 더 높은 효율을 나타냈다. In korea Wastewater treatment plants from aerobic process that organic remove was efficiency treatment but do not eliminate drain in the lake and river nitrogen and phosphorus by cause of eutrophication. This study was have designed pilot plant for fixed manufactured A2/O process and using the ceramics process. And test of wastewater treatment efficiency for effective treatment of nitrogen and phosphorus in wastewater. In case of A2/O modification process without ceramics, the removal efficiency of the process for T-N, T-P are 94%, 91.1% respectively. We have used three kinds of ceramics, those are functional, porous, and adsorptive. The functional ceramic showed the highest removal efficiency among them. In case of the process using three kinds of ceramics simultaneously, the removal efficiency of the process for T-N, T-P are 98.5%, 96.2% respectively.

안면비대칭 진단을 위한 하악골 3차원영상 계측기준치에 관한 연구

안정순,이기헌,황현식 대한치과교정학회 2005 대한치과교정학회지 Vol.35 No.2

기존의 2차원적 진단자료는 상의 확대 및 왜곡으로 인해 형태나 크기의 정량적 평가시부적절한 결과를 야기할 수 있어 안면비대칭의 정확한 진단과 치료계획 수립을 위해서는 3차원영상 진단의 도입이 필요하다. 본 연구는 안면비대칭 진단시 3차원적 분석에 도움이 되는 기준자료를 얻고자 정상교합자를 대상으로 하악골 3차원영상 계측항목의 평균값과 좌우차이의 정상범주를 알아보기 위하여 시행되었다. 뚜렷한 안면비대칭을 보이지 않는 성인 정상교합자 남녀 30명씩 총60명을 대상으로 두경부 전단화단층사진을 촬영한 후 컴퓨터 프로그램을 이용한 각각의 단면 촬영영상 정보를 이용하여 3차원 입체영상을 재구성한 다음, 하약골 비대칭시 좌우차이를 보일 수있는 계층항목 ramus length를 나타내는 6개 condyla neck length를 나타내는 1개, mandibular body length를 나타내는 8개 등 15개의 거리 계층항목과 gonial angle을 나타내는 4개, frontal ramal inclination을 나타내는 2개, lateral ramal inclination을 나타내는 2개 등 8개의 각도계층항목. 총 23개의 계층항목을 설정한 후, 좌측과 우측을 구분하여 컴퓨터 상에서 3차원계측치를 구하고 좌우차이값을 산출하였다. 본 연구결과 얻어진 정상교합자의 하악골 3차원영상 계층항목의 좌우차이값은 안면비대칭 환자의 진단 기준치로 유용하게 사용될 수 있을 것이다. For an accurate dlagnosis and treatment planning of facial asymmetry, the use of 3-dimensional(3-D) image is indispensable. The purpose of this study was to get standard data for the 3-D analysis of facial asymmetry.Computerized tomography(CT) was taken in the 60 normal occlusion individuals (30 male, 30 female) who did not have any apparent facial asymmetry. The acquired 2D CT DICOM data were input on a computer, and the reformatted 3-D images were created using a 3-Dimage software. Twenty three measurements were established in order to evaluate asymmetry:15linear measurements (6 for ramus length, 1 for condylar neck length, and 8 for mandibular body length) and 8 angular measurements (4 for gonial angle, 2 for frontal ramal inclination, and 2 for lateral ramal inclination). The right and left difference of each measurement was calculated and analyzed. Itis suggested that the right and left differences of the measurements obtained from the study could be used as references for the diagnosis of facial asymmetric patients.
