This study analyzes the factors involving clinical practice which have an influence on the satisfaction of students majoring in physical therapy at colleges or universities located in the Pusan and Kyungnam area. We investigated using a self-reporting method 305 students receiving a grade point average between 2.0 and 4.0 and who had finished their clinical practice. We also investigated the characteristics of clinical settings which make up the clinical practice, the general characteristics of the students involved and the characteristics of a clinical teaching method performed by physical therapists versus a teaching method by a professor of a university. The number of students divided according to educational background are as follows: 149 people (48.9% of the total group) were 4 year students, 156 people were 3 year students (51.1% of the total group). Sixty-nine students' or 22.6% of the group were men while women consisted of 236 persons or 77.4% of the group. Four year students had a longer clinical practice period than that of the 3 year students (p<.05). An average satisfaction score of students with their clinical practice was 3.84. The satisfaction scores showed no significant difference between genders, educational backgrounds, and grades. (p>.05). There were no significant differences in the satisfaction score of students with their clinical practice was 3.84. The satisfaction scores showed no significant difference between genders, educational backgrounds, and grades. (p>.05). There were no significant differences in the satisfaction scores regarding the student management system among varying gender or educational backgrounds between the 3 year and 4 year programs. The average satisfaction score with the environment of the physical therapy room was 3.35. And there were no significant differences in the physical therapy room satisfaction score based on sex or educational system (p>.05). The most influential factor of determining clinical practice satisfaction was a student management system of the clinical practice (p<.01). The next most influential factors were the clinical practice period (p<.05), size of facilities (p<.01) and relationship with physical therapists (p<.01) (=.554).

World Health Organization(WHO) revised the classification of neoplasms and other tumours related to odontogenic apparatus in 1992. The aim of this study was to classify the odontogenic tumors of Korean according to the WHO Histologic classification. A total of 271 cases were reviewed for the study which were diagnosed as odontogenic tumors at the department of Oral Pathology, Yonsei University College of Dentistry for the period from Jan. 1997 to March 2003. Clinical and pathology reports were reviewed & radiographic feature were examined. The following results were obtained : 1. Among 271 cases, 269 cases(99.3%) were diagnosed as benign odontogenic tumors, and the remaining 2 cases(0.7%) were malignant tumors, which were diagnosed as odontogenic ghost cell carcinoma and squamous cell carcinoma ex odontogenic cyst. 2. Four cases were not able to classify into the WHO classification. All of them were belonged to mixed odontogenic tumors; two cases of adenomatoid odontogenic tumor with calcifying epithelial odontogenic tumor, one case of adenomatoid odontogenic tumor with odontoma, odotogenic cyst and one case of ameloblastoma with immature odontoma. 3. The most frequent odontogenic tumour was odontoma(45.2%), followed by ameloblastoma (29.2%), odontogenic fibroma(9.2%) 4. One case of atypical amelobalstoma and one case of calcifying odontogenic cyst with ameloblastic fibroma were not able to subclassify histologically. 5. Male to female ratio of odontogenic tumors was 1.2:!. Odontogenic tumors mainly occured in the first and second decade, occurred twice as much as in the mandible than in the maxilla 6. The odontogenic tumors was discovered by routine oral x-ray examination, whereas the chief complaint of ameloblastoma were swelling, pain. 7. Ameloblastoma, adenomatoid odontogenic tumor, calcifying odontogenic cyst and odontoma were related to the impacted teeth and tooth displacement. The root resorption was frequently observed in ameloblastoma and calcifying odontogenic cyst.

The purpose of this study was to assess the effects of ultrasound on adjuvant-induced arthritis in rats. Adjuvant arthritis was induced in 26 female Sprauge-Dawley rats by the subcutaneous injection of a single dose of .1 mL of Complete Freund's Adjuvant (CFA) (1 mg of Mycobacterium Butyricum suspended in .1 paraffin oil) into the right hind paw. After confirming inflammatory edema and arthritis in the paw 2 weeks later, the arthritic rats were divided into 3 groups, i.e., a control group, a pulsed ultrasound group (Group A), and a continuous ultrasound group (Group B) with 8 rats placed in each group. The rats in Group A were treated with pulsed ultrasound at 1 MHz frequency with .5 intensity in 1 : 4 mode for 3 minutes. The rats in Group B were treated with continuous ultrasound at 1 MHz frequency with 2 intensity in the continuous mode for 3 minutes. The ultrasound treatment was done in the left and right ankles for 2 weeks. Clinical, radiographic and histopathologic findings were then evaluated before and after treatment and yielded the following results. 1. No significant difference was present in body weight between the control group and the treated groups. 2. A statistically significant decrease in the edema of the paw was seen in the rats in Group A that was treated with pulsed ultrasound by 26~29 days after the treatment started (p<.05). 3. According to radiological examination, Group A showed the lowest score in arthritis scale which means it showed a tendency to suppress arthritic inflammation of the left and right hind paws. However, no statistically significant difference was present in the score between the control group, Group A and Group B. 4. According to histopathologic findings, the degree of infiltration by inflammatory cells and hypertrophy of the synovium were less in Group A compared with the control group and Group B. The results of the study show that rats that were treated with the pulsed ultrasound effectively suppressed adjuvant arthritis. However, more effort is needed to objectively prove the effectiveness of ultrasound by developing more sensitive testing methods that could quantitatively evaluate the treatment effects of acute rheumatoid arthritis and by trying out different ultrasound treatment methods.

Odontogenic keratocysts(OKCs) are frequently associated with erupted or impacted tooth. In such instances, the radiographic features simulate those of a dentigerous cyst. The purpose of this study was to evaluate a comparative immunohistochemical expression of Ki-67 as a proliferative marker and apoptotic signals in the OKC associated with or without impacted tooth. In addition, we have also been investigated with regard to the proliferative activity and apoptosis comparing the unilocular and multilocular varieties of the OKC. The material for this study consisted of thirty-two cases of OKCs (OKC with impacted tooth, n=16；OKC without impacted tooth, n=16) and ten cases of dentigerous cysts as a comparison. The results revealed that the proliferative activity and apoptosis of OKCs with impacted tooth was higher than those of dentigerous cysts. However, there was no correlation between Ki-67 immunoreactivity or apoptosis and association with or without impacted tooth in 32 cases of OKCs. In addition, this present study showed that there was no correlation between the unilocular and multilocular varieties of the OKCs in proliferative activity and apoptosis.

1999년 6월부터 2002년 4월까지 총 2년 11개월 간 전국에서 발생한 소 유조사산에 대한 임상학적 연구결과는 다음과 같았다. 1. 계절별 소 유조사산 발생은 여름에 다른 계절에 비해 많이 발생하였다. 이는 여름철의 고온 다습한 기후와 낮은 우군관리 집중도에 기인한다고 사료된다. 2. 임신우의 산차별 유조사산 발생 비율을 조사한 결과 산차가 낮은 소에서 많이 발생하였다. 이는 유조사산의 원인이 임신우의 산차수에 있기보다는 산차수가 높은경우 사육되는

This study was performed to evaluate whether vitrification method using ethyle glycol and eletron microscopic (EM) grid could be used far the cryopreservation of human oocytes in ART program. Surplus oocytes were obtained from consented IVF patients. These surplus human oocytes were frozen with our vitrification method, Oocytes were exposed to 1.5M ethylene glycol (EG) in DPBS far 2,5 minutes, followed by 5.5M EG plus 1.0M Sucrose in DPBS for 20 seconds. Then oocytes were transferred onto the EM grid and the grid was plunged into LN2 for storage. For thawing, oocytes containing EM grid were sequentially transferred in 1.0M, 0.5M, 0.25M, 0.125M and 0 M sucrose in DPBS solution at the intervals of 2.5 minutes. Thawed and survived oocytes were provided for ICSI. Embryos from vitrified oocytes were transferred to uterus of the patient on 4 to 5 days after ovulation in natural cycles of on 15 to 17 day of hormone replacement cycles. A total of 370 oocytes from 26 patients were thawed and 159 (43.0%) of them survived. One hundred thirty four oocytes (84.3%) were fertilized normally and 126 pre-embryos were transferred to 26 patients, resulting in 5 clinical pregnancies. The pregnancy rate per transfer was 19.2% and implantation rate was 4.0%. Among the five pregnant, 4 patients delivered 4 healthy babies and the one patient was 32-week ongoing pregnancy. From this results, vitrification using ethylene glycol as cryoprotectant and EM grid is a rapid and simple method that can be effectively applied for the cryopreservation of human oocytes in ART program.
