뒤쥐(Sorex caecutiens) 혀유두의 형태적 특징을 알아보기 위해 주사전자현미경을 이용하여 관찰하였다. 혀유두는 실유두, 버섯유두 그리고 성곽유두의 세 가지 유형으로 관찰되었다. 실유두는 혀측면을 제외하고는 혀의 전역에 걸쳐 분포하고 있었으며, 형태와 구조적 특징을 기초로 하여 세 가지의 유형으로 구분되어졌다. 다수의 버섯유두는 혀 전체에 걸쳐 분포하였으며, 특히 혀의 양 측면에 걸쳐 존재하고 있었으며, 혀의 앞쪽보다는 뒤쪽으로 갈수록 크기가 더 컸었다. 버섯유두는 쌍을 이루며 분포하지는 않았지만, 대부분 일정하게 분포하였다. 큰 2개의 성곽유두는 혀의 후방부의 끝 가까이에 존재하고 있었다. 성곽유두는 바깥쪽(측면)이 두꺼운 두겹의 pad가 둥글게 둘러싸고 있었으며, 중앙에는 2개 혹은 3개 정도의 돌출된 둥글게 둘러싼 pad가 존재하고 있었다. 본 연구 종은 일반적인 뒤쥐류에서 볼 수 있는 혀의 형태와 거의 흡사한 구조를 가지고 있었음을 알 수가 있었다. 본 연구에서 성곽유두는 Sorex 종과는 차이가 있었다. 즉, 박쥐류와 Sorex 종에서와 같이 바깥쪽의 pad가 환상의 형태를 취하고 있다는 점에서는 동일하나 박쥐류와 Sorex 종의 경우는 바깥쪽의 pad가 한 겹인데 반해 본 연구 종은 두 겹의 환상 구조를 취하고 있다는 점에서 차이가 있었다. The dorsal lingual papillae of Sorex caecutiens were studied morphologically using scanning electron microscopy. Three types of lingual papillae were found: filiform papillae, fungiform papillae and circumvallate papillae. Filiform papillae were observed in most part of the tongue except on the lateral surface. There were basically three types of filiform papillae distinguished mainly by their morphological shape and structure. Numerous fungiform papillae were spread throughout the whole tongue, especially concentrated in lateral sides. The size varied according to the position of fungiform papillae, becoming larger as it reached to the rear. Strict pair-wise distribution was not observable, but fungiform papillae were mostly located in orderly manner. There were two large circumvallate papillae at the posterior region of the tongue. There were two thick pads around the center part where several bodies were gathered together. Overall research provided similar results with other close species such as common shrew (S. araneus). The circumvallate papillae of S. caecutiens were different from other Sorex species. They were circular, as in bats and other Sorex species, and had two distinguishable pads while others had only one.

주사전자현미경을 이용하여 한국산 긴가락박쥐(Miniopterus schreibersi fuliginosus)와 검은집박쥐(Pipistrellus savii)의 혀유두의 형태를 관찰하였다. 본 연구에서 두 종 모두 세 가지의 혀유두, 즉, 실유두, 버섯유두 그리고 성곽유두가 관찰되었다. 실유두는 다시 두 종류로 세분화되어졌으며, 침상의 돌기물을 갖는 유형1은 혀의 전반부의 1/2 지점까지 분포하며, 유형2는 밋밋하고 두꺼운 돌기물을 갖고 있으며 혀의 후반부의 1/2에 분포한다. 두 종 모두 35~45개의 버섯유두가 혀의 표면에서 관찰된다. 이들 버섯유두는 혀의 측면과 혀의 전반과 후반부의 끝 쪽에서 나타난다. 두 종의 버섯유두는 각각 두 개 혹은 세 개의 매우 큰 유두로 혀의 후반부 중앙에 일직선으로 배열되어 있다. 두 개의 성곽유두는 혀의 후반부 끝쪽 가까이에 분포하고 있다. 이들 성곽유두는 크고 둥글며 각각은 두 층의 pad를 갖고 있다. 긴가락박쥐와 검은집박쥐의 혀유두의 전체적인 형태는 다른 익수류와 유사하였다. 그럼에도 불구하고, 두 종 사이에 드물지만 주목할 만한 차이점이 실유두와 버섯유두에서 나타났다. 검은집박쥐와는 달리 긴가락박쥐의 유형2의 실유두는 두 개 혹은 세 개의 돌기를 가지고 있었다. 혀의 후반부 중앙에 위치하고 있는 큰 버섯유두의 경우, 긴가락박쥐에서는 3개, 검은집박쥐에서는 단지 2개만 관찰되었다. A SEM study on morphology of lingual papillae of Korean long-fingered bat (Miniopterus schreibersi fuliginosus) and Savi's Pipistrelle (Pipistrellus savii) was conducted. Three kinds of lingual papillae were observed: filiform, fungiform, circumvallate papillae. Filiform papillae were divided into two types; the type 1 had a group of needle-like projections, and was distributed throughout the front half of the tongue; the type 2 had a smooth and thick body, and was found in rear half of the tongue. 35 to 45 fungiform papillae were found on the dorsal surface of the tongue in both species. They were observed along the lateral margins and were also found on front and rear end part of the tongue. There were two to three noticeably large fungiform papillae arranged in a straight line on the region between lingual prominence and circumvallate papillae. There were two circumvallate papillae close to the rear end of the tongue. They were large and round, each having two layers of pads. The overall morphology of lingual papillae of M. schreibersi fuliginosus and P. savii was found to be similar with other Chiroptera. However, few but noticeable differences were found among the filiform papillae and fungiform papillae. Type 2 filiform papillae differed in that bifid and trifid configuration were found in M. schreibersi fulginosus unlike in P. savii. In addition, numbers of large fungiform papillae located in the center of posterior region of the tongue were different with M. schreibersi have three while P. savii having only two.

In this study, two types of thick steel plates are prepared by controlling carbon equivalent and nickel content, and their microstructures are analyzed. Tensile tests, Vickers hardness tests, and Charpy impact tests are conducted to investigate the correlation between microstructure and mechanical properties of the steels. The H steel, which has high carbon equivalent and nickel content, has lower volume fraction of granular bainite (GB) and smaller GB packet size than those of L steel, which has low carbon equivalent and nickel content. However, the volume fraction of secondary phases is higher in the H steel than in the L steel. As a result, the strength of the L steel is higher than that of the H steel, while the Charpy absorbed energy at -40 ℃ is higher than that of the L steel. The heat affected zone (HAZ) simulated H-H specimen has higher volume fraction of acicular ferrite (AF) and lower volume fraction of GB than the HAZ simulated L-H specimen. In addition, the grain size of AF and the packet sizes of GB and BF are smaller in the H-H specimen than in the L-H specimen. For this reason, the Charpy absorbed energy at -20 ℃ is higher for the H-H specimen than for the L-H specimen.

Purpose: The objectives of this study were to explore the relationships between the fear of falling and daily activities, and physical functioning of older people in community. Method: A descriptive study design was used in this study. 295 people aged over 65 and living in community participated. Data of demographic characteristics, fear of falling, activity daily living, physical functioning were collected. Result: 13.2% of the participants reported that they have falling accident last one year. 75.6% of participants reported fear of falling. 67.7% of them expressed restricting activity because of fear of falling. There were no significant relationship between fear of falling and BADL(Basic Activity Daily Living) but fear of falling and IADL(Instrumental Activity Daily Living) were related. It was also found that older people with higher fear of falling expressed more pain and uncomfortable feelings especially on their lower body and had higher scores of morbidity of neurologic diseases such as neuralgia and cerebrovascular diseases. Conclusion: There were significant relationships between fear of falling and IADL, and physical functioning on lower body, and morbidity of neurologic diseases such as neuralgia and cerebrovascular diseases.

Purpose: To identify the health condition, home care support, support requirement of poor and elderly people living alone. Method: Data was collected through self-administered questionnaires and analyzed by descriptive statistics, t-test, ANOVA and correlation. Survey involved 269 conveniently selected who have a social support in H city. Result: Perceived health condition of subjects was bad to moderate (mean score: 2.22). There were significant home care support differences according to gender, religion, education level and dwelling pattern. Support requirement was influences only by the dwelling pattern. Perceived health condition showed a positive correlation with home care support of friends and neighbors, and a negative correlation with support requirement (medical, material, economic emotional support). Conclusion: These findings are expected to make a positive contribution to create an ideal intervention for public visiting nurses and social workers to improve the quality of life in poor and elderly people who live alone.

Purpose: Home health nurses could affect patients' choice of alternative therapy. This study was carried out to investigate home health nurses' attitudes and cognition toward alternative therapy. Method: The subjects were 92 nurses who preparing the home health nurses at 2 university in Seoul and Suwon. Using the questionnaire. we measured the subjects' attitudes and cognition toward alternative therapy. Result: The mean score of attitudes about application was 3.14. and the score of attitudes about therapeutic effect was 2.57. The score of attitudes about therapeutic effect were significantly positive correlation to the score of cognition about alternative therapy. The attitudes about therapeutic effect were different significantly according to number of working years. But they commonly wanted to apply the soojichim. aroma-therapy. massage. danjon breathing. music therapy. plant therapy. and foot reflexology to their home health care subjects. Conclusion: Alternative therapies became a popular source of health care in Korea. This study showed pre-home health nurses had positive attitudes toward alternative therapies and they had wide variations of knowledge in how to use each therapy. But they acknowledge the value of alternative therapies as useful nursing interventions. so we all nurses should pay attention to develope the nursing intervention using alternative therapy.

Purpose: This study was to delineate the structural change of neural pathway after sequential motor learning using diffusion tensor imaging (DTI). Methods: The participants were 16 healthy subjects, which were divided by training (n=8) and control (n=8) group. The task for the training was the Serial Reaction Time Task (SRTT) which was designed by Superlab program. When the 'asterisk' shows up in the 4 partition spaces on the monitor, the subject presses the correct response button as soon as possible. The training group participated in the training program of motor learning with SRTT composed of 24 digits pattern in one hour per daily through 10 days during 2 weeks. Results: In the behavioral results the training group showed significant changes in the increase of response number and the reduction of response time than those of the control group. There was significant difference in the left inferior frontal area in the fractional anisotropy (FA) map of the training group in DTI analysis. Conclusion: Motor sequential learning as like SRTT may be needed to the learning of language and visuospatial processing and may be induced for the experience-dependent structural plasticity during short period.
