In order to determine whether vegetation would be one of the factors for the selection of otter home range, vegetation structure and other potential factors were studied in Hwacheon, Korea. Thirteen sites, otter’s activity found and not found, were investigated in North Han River and connected tributary streams of Hwacheon-gun. Three types of vegetation were classified by cluster analysis, which is short grass, tall grass and shrub type. Vegetation zone of each channel is composed of either one type, or mosaic of tall grass and shrub type. Short grass type is common in Lake Paro and upper North Han-river where water level is highly variable throughout a year. Therefore, annual species such as Persicaria nodosa, Fimbristylis dichotomam and Chenopodium ficifolium are the most dominant. Shrub type is common at the downstream sites of Jichon stream and along mainstream of North Han River down Lake Paro. A shrub species, Salix koreensis, is the most common. Tall grass type is dominant occupying the most vegetation zone of the tributary channels. Phragmites japonica is absolutely dominant. Due to its dense cover, a few plant species are co-existed. Otter activity was found in all three vegetation types and no marked activity was found at some sites of tall grass type. There is no difference in species composition and physiognomy between tall grass sites with and without otter activity, while it shows significant difference in fish availability between two groups. Overall we found that home range of otters in the region is along the mainstream and downstream of tributary streams with high fish availability in all vegetation types and in various human activity levels.

Internal derangement of the temporomandibular joint can be defined as an abnormal relationships of the meniscus relative to the mandibular condyle, articular fossa and eminence. This may cause variable mandibular dysfunctions and pain. For diagnosis, arthrography, computed tomography and magnetic resonance imaging are used. In this study, the authors reviewed 98 TMJs of 88 patients who were diagnosed as internal derangement through inferior joint space arthrography at the department of Oral & Maxillofacial Radiology, Dental Hospital, Dankook University through 1986 to 1992. 98 TMJs consisting of 30 disc displacement with reduction, 48 disc displacement without reduction and 20 perforation were studied about clinical and radiological findings. The results were as follows : 1. Internal derangement was found most frequently in the 2nd and 3rd decades and the average age of perforation was higher than that of disc displacement with reduction. The sexual predilection was 2 times higher in females. 2. The most frequent chief complaints were TMJ sound in displacement with reduction, pain and limitation of mouth opening in disc displacement without reduction and pain in perforation. The duration of the chief complaints was longer in disc displacement with reduction than in preforation and disc displcement without reduction. 3. Reciprocal click was the most frequently TMJ sound in disc displacement with reduction. History of joint sound in disc displacement without reduction and crepitus in perforation was the most frequent one. 4. The average maximum opening was 45.4mm in disc displacement with reduction, 31.4㎜ in disc displacement without reduction and 33.8mm in perforation. 5. In the centric occlusion, posterior condylar position was the most frequent in disc displacement with reduction, posterior and concentric condylar position was frequent in disc displcement without reduction, concentric and anterior condylar position in perforation. At 1 inch opening, the same position to articular eminence was most frequently found in disc displacement with reduction, posterior position in disc displacement without reduction, posterior and anterior position in perforation was frequently found. 6. Bony changes, especially sclerosis and flattening, was most frequently found in perforation.

The purpose of this study was to collect basic data for the development of oral health education program of parents and to encourage their actual interest and participation in school oral health program. The authors surveyed parents' awareness and behaviors about the oral health of their children. The subjects in this study were 193 parents of elementary school children in Seoul. The collected data were analyzed, the obtained results were as follows: 1. Thirty-five percent of the parents investigated paid a regular visit to a dental clinic. The must common tooth brushing time among them was after dinner, the second was after breakfast, and this was followed by before bedtime and before breakfast. 2. Ninety-four percent of the parents responded that prevention is necessary, 92.2% had a plan to visit a dental clinic to prevent dental caries, and 60.1% experienced receiving pit and fissure sealants. Ninety-seven percent responded that they did check their children's dental caries. 54.9% chocked their children's oral status after tooth brushing. The parents who visit a dental clinic on a regular basis were more likely to check their children's teeth after tooth brushing than those who don't(P<0.05). 3. Eighty eight percent of respondents wanted to keep the fluoride mouth rinse program. 4. It is recommended that an oral health education program be developed for parents to visit dental clinics on a regular basis, to educate as to the right tooth brushing time, and to check out their children's oral status after tooth blushing.

Sj□gren's syndrome is a chronic inflammatory disease that predominantly affects salivary, lacrimal and other exocrine glands. We report a case of Sj□gren's syndrome combined with MALT (mucose associated lymphoid tissue) Iymphoma which occured in the parotid gland. A 57-year-old female with the complaint of painful swelling and iymph node enlargement was referred to our department. Sialograms of both parotid glands showed globular collections of contrast material uniformly distributed throughout the parotid gland. Salivary scintigraphy showed decreased uptake of the parotid gland. CT scan showed larger, slightly more dense parotid gland than normal and honeycomb glandular appearance. Also, It showed discrete, slightly more enhanced round mass in the left parotid gland. Histopathological finding showed replacement of salivary gland parenchyma with dense small lymphocytic infiltration having the feature of epimyoepithelial islands. Kappa light chain restriction of interglandular plasma cell could be seen. (Korean J Oral maxillofac Radiol 2000; 30: 144-148)

The purposes of this study were to investigate the effect of integrated poem activities on young children's language and perspective-taking abilities. The subjects were 40 5-year-old children in public kindergarten of D elementary school in Chonju City, Chung-buk area. Children were divided into two groups. One was experimental group which was exposed to integrated poem activities, and the other was control group. To assess children's language, cognitive and affective perspective taking abilities, K-ABC(Korean Kaufman Assessment Battery for Children) and Kurdek & Rodgon's perspective taking test were used. To analyse data, frequency, mean(M), standard deviation(SD) and Mann-Whitney test of non-parametric statistics were used. The results of this study were as follows. First, the language abilities of children with exposure to integrated poem activities were higher than those of control group. Second, the affective perspective taking abilities of experimental group were higher than those of control group. Third, no difference was found in cognitive perspective taking abilities according to treatment conditions. Fourth, among children with treatments, no sex difference was found in language, affective perspective taking and cognitive perspective taking abililties. The results of this study indicate that the integrated poem activities are effective tools for improving young children's language and perspective taking abilities.

본 연구의 목적은 현대여성의 구두 착용에 따른 발 및 주변 부위의 문제점을 밝히는데 있다. 본 연구에서는 주된 구두 소비자 계층인 20대 여성들을 대상으로 소비자 설문조사를 통하여 구두 착용현황 및 그에 따른 발 장애를 살펴보고 구두 제작시 필요한 기초자료를 제공하고자 하였다. 본 연구의 결과를 살펴보면, 구두 착용여성의 대부분이 연령과 착용시간에 관계없이 많은 장애를 경험하였다. 그러므로 구두장애 요인 중 가장 많이 지적된 ‘구두골 치수’와 소재의 개선이 요구된다. 특히, 발둘레 치수에 대해서는 소비자와 판매자의 인지도가 약해 적절히 사용되지 못하고 있으므로 KS 규격에 대한 홍보가 필요하다. The purpose of this study was to identify the problems of women’s feet and it’s relative area caused by wearing shoes. This study was conducted through a survey with 384 young women consumers of 20s. Most respondents indicated that problems while wearing shoes. The reasons of the discomfort were ‘unfit of the size’ and ‘inappropriate materials.’ Most respondents were found to have the knowledge of their sizes but not of the letter sizes for the foot girth. Seventy six percent indicated that they of the respondents rarely know about the letter size. Most of the respondents (92.5%) indicated that they never checked the letter size when purchased shoes. This implicates that consumer education concerning the ‘KS G 3405 Lasts for shoes’ size system is necessary.

Background Human endogenous retroviruses (HERVs) constitute around 8% of the human genome and have important roles in human health and disease, including cancers. Previous studies showed that HERV envelope (Env) proteins are highly expressed in cancer tissues and co-related with cancer progression. KAP1 has been reported to play a key role in regulating retrotransposons, including HERV-K, through epigenetic silencing. Objective The relationship between KAP-1 and HERV Envs expressions was analyzed only in tumor cell lines and has not yet been studied in cancer tissues. In this study, we analyzed the expression patterns and relationship between KAP1 and HERV Env proteins in ovarian cancer tissues. Method The expression patterns of KAP-1 and HERV Env proteins, including HERV-K and HERV-R, were analyzed in ovarian cancer tissue microarrays that contained 80 surgical specimens, including normal ovary and malignant ovarian cancers. Results The expression of HERV-R Env and KAP1 proteins is signifcantly higher in ovarian cancer compared with normal ovary tissues. However, the expression of HERV-K Env did not change signifcantly in cancer tissues. The expression patterns of HERV-K Env and HERV-R Env signifcantly increased in early stages of cancer and KAP1 expression was higher in certain stage and types of cancers. However, the expression of HERV-K Env, HERV-R Env, and KAP1 did not change in diferent age groups. The correlation between the expression of KAP1 and HERV-Env, including HERV-K and HERV-R, was not signifcantly correlated. Conclusions The results of this study showed that there was no signifcant correlation between the expression of KAP1 and HERV Env proteins in ovarian cancer tissues, unlike studies with cell lines in vitro. These results suggest that the actual expression of HERV Env proteins in ovarian cancer tissues may be regulated through various complex factors as well as KAP1.

Familial gigantiform cementoma is a rare fibro-cemento-osseous disease of the jaws which appears to be transmitted as an autosomal dominant trait with variable expressivity of the phenotype. A 7-year-old girl visited DKUDH complaining of the painless facial deformity. Clinically, significant facio-lingual expansion was observed at the left maxilla, left mandibular body and symphysis portion. Malposition of lower anterior teeth was found. Panoramic radiograph and CT scan showed the extensive expansile mixed lesion at maxilla and mandible. Bone scan revealed hot spot at the maxilla and left side of mandible. Histologic examination revealed moderately dense fibrous connective tissue with scattered masses resembling cementum. The patient's mother had a history of the mandibular resection due to benign tumor. Her younger brother had buccal expansion of right mandible. We report our finding of a family that has exhibited clinical, radiographic and histologic findings consistent with the familial gigantiform cementoma.
