This paper presents a method for precisely localizing and parking of bimodal trams. In order to gain an automatically driving system for bimodal trams, precise up-to-date localization, velocity recognition, distance to next station and precise parking location estimation functions are required. This paper proposes a system consisting of control device, steering device, sensor input equipment, driving system, tachometer, vehicle-side sensors, magnetic markers and magnetic sensors. The tram recognizes the precise location via magnetic markers containing information. Parking position and precise distance calculation is embodied by a tachometer. The vehicle-side sensors are used to assure safe station approaching and parking magnetic markers provide improvement of precision while tram parking. This paper provides a system realizing localization and precise parking and afterwards the automatic drive test results are reported and analyzed.

Fungi are well suited for studying mechanism controlling development and cell differentiation in multicellular eukaryotes. The asexual and sexual reproductive cycles are tightly coordinated during the life cycle of Aspergillus nidulans. The asexual (mitotic) reproductive cycle involves the formation of a number of differentiated cell types. Successful formation of multicellular reproductive structures and spores (conidia) requires the establishment of spatiotemporal gradients in essential transcriptional regulators, such as brlA, abaA and wetA. Altered gene expression is coordinated with critical changes in the movement of nuclei and the regulation of the cell division cycle. Therefore, it has been proposed to define a central regulatory pathway. Several early regulatory genes involved in signal transduction pathway controlling asexual sporulation are also required for activating the central pathway. Sexual (meiotic) reproduction is more complex, requiring the differentiation of several specialized tissue types. Although technical difficulties have limited efforts to study the genetics of sexual fruiting-body formation directly, some recent progress has been made. With the recent availability of mutants blocked in sexual development, understanding the genetic interactions between genes that function primarily in determining sexual sporulation will be achieved in the near future.

As a nursing practice involves nurses' actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives, Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal) ; excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, account- ability and commitment(4 theories of nursing ethics) ; human respect. partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences. positive perspectives(4 theories of nurse), role of intervention. rewarding peer relationship(3 theories of situations) The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore. it is recommended to review the theories-in-use in order to and any discrepancies between the espoused theories and the reality of nursing actions

박기오,채경훈,허원석,강윤세,정재훈,김연수,문희석,이엄석,김선문,이병석,김남재,이헌영 충남대학교 의과대학 의학연구소 2003 충남의대잡지 Vol.30 No.1

목적 : 최근 8년간 본원에서 경험한 자기면역성 간염의 혈액학적 특징과 스테로이드의 치료효과를 알아보고자 본 연구를 시행하였다. 방법 : 1996년 이후부터 2002년까지 충남대학교 병원에서 1999년 International Autoimmune Hepatitis Group(LAHG)에서 제시한 수정 진단 기준안에 의거하여 총 진단점수가 probable 이상에 해당하는 환자들을 대상으로 임상적 특징, 검사실 및 조직 소견과 스테로이드와 azathioprine의 치료 효과를 후향적으로 조사하였다. 결과 : 9예의 환자들은 여성이 78%, 40대가 많았고, 급성 발병이 33.3%, 피로감, 식욕부진 및 황달 등이 나타났으며, 항핵항체가 55.6%에서 그리고 항평활근 항체가 77.8%에서 양성이었고, 동반 질환은 류마치스 관절염이 2예, 특발성 혈소판 감소증 1예, Henoch-Sch nlein 자반증 및 그레브스병이 각각 1예 씩이었다. 7예에 대해서 스테로이드와 azathioprine으로 치료하여 생화학적 임상적 완해가 이루어져서 유효한 치료 결과를 얻었다. 결론 : 자가면역성 간염은 우리 나라에서 원인을 찾을 수 없는 만성 간질환의 경우, 특히 중년여성에서 다른 자가면역성 질환이 동반되었을 때 자가면역성 간염을 의심하여 자가항체 선별검사를 시행해 보아야 할 것으로 생각된다. 향후 다기관 연구를 통하여 좀 더 많은 증례를 모으고 전향적인 연구를 시행하여야 할 필요가 있다. Although autoimmune hepatitis(AIH) is common in western contries, some studties have been reported in Korea. The aim of the study was to analyze the clinical and histological features and expression pattern of the autoantibody and to examine clinical course of AIH in Korea. For 9 patients diagnosed as having AIH in our hospital since 1996, we reviewed medical records and analyzed clinical and laboratory findings retrospectively. They had a probable or definite AIH according to the revised criteria of International AIH group. The mean age was 42.7(21∼68)years and 7(77.8%) were female. Three of them(33.3%) showed acute hepatitis and five of them showed cirrhosis. Fatigue and anorexia were the most frequently complained symptoms(55.6%). Four patients(44.4%) were accompanied with other autoimmune diseases. Antinuclear antibody was detected in 5(55.6%) and anti-smooth muscle antibody was detected in 7(77.8%). Three patients showed focal picemeal necrosis and four showed periportal fibrosis. Among 7 patients who received immunosuppressive therapy, six patients(85.7%) showed initial response. and biochemical and serologic remission were achived in 5(71.4%) and 3(42.8%) patients, AIH seems to be partly responsible for chronic liver disease of unknown etiology in Korea. AIH should be suspected in female patients with unknown chronic liver disease of unknown etiolgy, especially accompanied with other autoimmune disease. The clinical characteristics of AIH may not be quite different from those of Western countries.

This study was conducted to examine the growth change in external nose according to age which plays an important role in determining the facial profile, by analysing the biennial serial lateral cephalograms of 20 males and 20 females of mean 8.5 years old to 16.5 years old who have a normal occlusion. The results of this study were summarized as follows. ㆍBoth mean and standard deviation were obtained according to each item, sex and age for the male and female. ㆍNose heights of the male and female increased with increase in their age. The upper to lower nose height ratio somewhat decreased for both male and female with increase of age. The mean ratio was 3.69:1 for the male, respectively, and 3.83:1 for the female during this study. ㆍThe nose depth indicated the most significant increase of all items according to the increase of age, while the sagittal depth inicated higher value for the female than that of the male in the most age groups. ㆍThe nose inclination did not show a remarkable change during this study. ㆍThe proportions of growth completed at the earliest age showed the highest percentage for sagittal depth(male : 87.14% & female : 91.29%). Also, the male indicated the lowest percentage in lower nose height(73.04%), while the female did the lowest in nose depth(79.09%). ㆍThere was shown the variable of the greatest correlation between the upper nose inclination and nose depth. ㆍFrom this study, the whole external nasal growh was occurred downward and forward which was more frequent for forward growth than vertical growth.
