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

The purpose of this study was to provide the basic data for industrial nurses to perform their duties effectively, by comprehending the health problem of the industrial workers. The study was undertaken from October 1 to December 30, 1989. The subjects were 495 workers of the textile industry and 999 workers of the machine industry in some industrial corps. The interrelationship between workers' general characteristics and their perceived symptoms, and between the factors relating with the kinds of job and their perceived symptoms was examined and analyzed according to the type of industry. The results were as follows : A. The difference of the degrees of perceived symptoms according to general characterisrics. The degrees of appealing for perceived symptoms according to : 1. age : the younger, the higher. 2. sexuality : female was higher than male. 3. marriage : unmarried were higher than married. 4. level of education : high school graduates were the highest in the machine industry, and middle school graduates were the highest in the textile industry. 5. residence : workers living in the dormitory were the highest. 6. mealtime : the more irregular was the mealtime the higher became the degree. 7. smoking : non-smokers were the highest. B. The difference of the degrees of perceived symptoms according to the kinds of job. The degrees of appealing for perceived symptoms according to : 1. job experience : workers of four-year experience were the highest in the machine industry, and those of two-year experience were the highest in the textile industry. 2. department : workers of assembling department were the highest in the machine industry, and those of packing department were the highest in the textile industry. 3. working-posture : 1) workers working at sitting posture were high in eye symptoms in the machine industry (P < 0.0001). 2) workers working at standing posture were high in musculo-skeletal symptoms in the textile industry(P < 0.01). 4. kinds of job : 1) workers working in the noisy environment were high in musculo-skeletal symptoms in the machine industry, and in neural and mental symptoms in the textile industry(P < 0.0001). 2) workers dealing with manual job and weighty things were high in musculo-skeletal symptoms both in the machine and in the textile industry. 3) workers working a long time with the same posture were high in neural and mental, musculoskeletal, and eye symptoms both in the machine and in the textile industry(P < 0.0001). 5. environment of working area : both in the machine and in the textile industry. 1) workers with illumination problem were high in eye symptoms(P < 0.005). 2) workers with ventilation problem were high in musculo-skeletal symptoms(P < 0.0001). 3) workers with natural lighting problem were high in integumentary symptoms. 6. satisfaction with their work : both in the machine and in the textile industry, the more dissatisfied with their work they were the higher became the degrees of their perceived symptoms. 7. satisfaction with their working condition : both in the machine and in the textile industry, the more dissatisfied with their working condition they were, the higher became the degrees of their perceived symptoms.

연구목적 : 다면적 인성검사를 통해 이갈이군의 심리적 특성을 알아보고 이갈이 환자의 성별, 가족력, 발병기간, 이갈이 유형, 동반된 통증 유무에 따른 심리적 특성의 차이를 알아보고자 하였다. 방 법 : 1998년 1월부터 8월까지 개인 치과의원을 방문한 환자들 중 46명의 이갈이군, 41명의 대조군을 대상으로, 이갈이군과 대조군의 심리적 특성, 이갈이 환자의 성별, 가족력 유무, 이갈이 기간, 이갈이 유형, 통증과 같은 동반증상유무에 따른 심리적 특성의 차이를 알아보기 위해 다면적 인성검사를 실시하였다. 결 과 : 이갈이군이 대조군보다 모든 임상척도에서 높은 점수를 나타냈으나 남성특성-여성특성 척도점수를 제외하고는 통계적 유의성이 없었다. 가족력이 있는 이갈이군이 가족력이 없는 이갈이군보다 반사회성 척도가 높았다. 이갈이군에서 남자가 여자보다 교정척도(K) 점수가 높게 나타났으며 여자는 편집증 척도점수가 높게 나타났다. 발병기간에 따른 차이는 없었으며 이갈이 종류의 비교에서는 이악물기형이 다른형보다 내향성 척도가 유의하게 높았다. 저작근 통증, 경통, 두통과 같은 동반된 통증 유무에 따른 차이는 없었다. 결 론 : 다면적 인성검사상 일부 항목에서 높은 점수를 나타낸 것으로 이갈이 환자의 심리적 특성을 규정짓기는 어려우나 이갈이군이 대조군에 비해서 다면적 인성검사상 모든 척도가 상승되어 있고, 이갈이의 성별, 가족력, 이갈이의 종류에 따라 일부 척도의 점수가 상승되어 있는 것은 이들이 서로 다른 심리적 특성을 가질 가능성을 시사한 것이라고 판단되며, 이는 치료에 있어서도 좀 더 개별화된 접근이 필요함을 시사한다. Objectives : The aim of this study was to evaluate the psychological characteristics of the patients with bruxism by Minnesota Multiphase Personality Inventory (MMPI). Methods : MMPI was administered to 87 patients(46 bruxism group and 41 control group) who had visited a local dental clinic from January to August 1998. Results : The bruxism group had a higher score than control group in Masculinity-Femininity (Mf) scale. There were no differences between bruxism group and control group on the distribution of Depression(D), Psychopatic Deviate(Pd), Paranoia(Pa), Psychasthenia(Pt) scales. The bruxism group with the family history showed higher score than the bruxism group without family history in Pd scale. Male bruxism group had a higher score than female bruxism group in Defensiveness(K) scale and female bruxism group had higher score than male bruxism group in Pa scale. The bruxism group of clenching type had a higher score than the bruxism group of mixed type in Social Introversion(Si) scale. There were no differences in MMPI score between those who had and did not have symptoms such as masticatory muscle pain, neck pain, and headache. Conclusion : It is concluded that individualized approach may be effective to the evaluation of psychological disturbances which might be related to sex, family history and, type of bruxism, while we did not find significant differences in personality characteristics between the bruxism and control groups.

Triton Ⅹ-100이 Trichoderma koningii의 성장 및 형태에 미치는 영향을 조사하기 위하여, Triton Ⅹ-100 첨가 여부에 따른 각 종 성장계수의 변화를 조사하여 보았다. 액체 배양시 Triton Ⅹ-100의 첨가에도 불구하고, specific growth rate과 doubling time은 변화가 없었으나, Triton Ⅹ-100을 첨가한 경우, 군체의 방사상 성장률이 감소하였다. 이러한 현상은 Triton Ⅹ-100에 의하여 균사의 분지 형성이 촉진되고, 격막형성이 촉진되어 격막 간의 간격이 짧아져 나타나는 것으로 확인되었다. We investigated the effect of Triton Ⅹ-100 on the growth and morphology of Trichoderma koningii by comparing various parameters representing the growth of mold in the presence or absence of Triton Ⅹ-100. The specific growth rate and doubling time of T. koningii were not affected by the addition of 0.05% Triton Ⅹ-100 into solid medium also resulted in decrease in the colony radial growth rate and this response was correlated with the formation of mycelia which showed increase in branching and septation in the presence of Triton Ⅹ-100.

知能 및 人性的 要因과 外國語學習 成就度 間의 相關性에 관한 硏究

朴熙文 培材大學校 1985 論文集 Vol.6 No.-

The purpose of the study is twofold : first, to investigate the correlationship between intelligence and foreign language proficiency, second, to discuss the influence of personality factors on foreign language achievement, To identify the relationship between intelligence and 1anguage proficiency, 215 students from Pai Chai College were selected as research subjects. The research result reveals that the correlation between the two is r = 0.009, which means no correlation at all. This result implies that students' IQ level should not be used as an exclusive indication of the students' foreign language attainment, and that every student be equally treated as qualified individuals who can achieve the same goal. As for the corelationship between personality factors (e.g., attitude, motivation, self-esteem, ego) and foreign language proficiency, existing related literatures were carefully reviewed. The research results reveal that attitudinal characteristics of the student are important in the acquisition of a foreign language. The nature of these characteristics suggests that the truely successful student is motivated to become integrated with the other language community. The integrative motive appears to derive from the attitudinal characteristics in the home and must be fostered by an accepting attitude, by the parents, concerning the other language group. The process of second language acquisition involves taking on behavioral characteristics of the other language community and the fact that the child will experience resistence from himself and pressures from his own cultural community.

해수에서 분리한 Vibrio sp. M-96 균주의 열감수성 alkaline phosphatase 성질

박문경,진덕희,김중균,공인수,김광현,홍용기 동의대학교 기초과학연구소 1997 基礎科學硏究論文集 Vol.7 No.1

A thermolabile alkaline phosphatase has been purified through steps of osmotic shock, ammonium sulfate salting-out, and DEAE-cellulose chromatography from the cultured broth of the marine Vibrio sp. M-96 strain. The optimal temperature for the enzyme activity was 35℃. The optimal pH was pH 11.0, and the range of pH stability was pH 10.4 to 12.0. Thermal inactivation occured within 6 minutes at 60℃. The enzyme was considerably inactivated by 0.1mM concentrations of Hg^2+, Ni^2+ and Zn^2+, whereas activated up to 234% by 1mM of Mn^2+. The activation energy and deactivation energy by the Arrhenius equation were 4.02 Kcal/mol and 9.09 Kcal/mol, respectively. The Km and Vmax values of the enzyme for p-nitrophenylphosphate were found to be 0.0465mM and 0.001335mM/min. respectively. Active from of the enzyme had a molecular weight of 57,000 dalton determined by the Sephadex G-200 gel filtration method.

話題化 變形(Topicalization)에 관한 GPSG 分析 硏究

朴熙文 培材大學校 1985 論文集 Vol.7 No.-

The purpose of the study is two fold : one is to survey the general framework of GPSG theory, art the other is to apple the theory to the topicalization of English and Korean, The classical TG theories on topicalization, that is, deletion hypothesis, movement hypothesis, and phrase structure hypothesis failed to provide comprehensive explanations on the theme, Recently however, the GPSG theory proposed by Gazdar et al. shows the possibility that all of the syntactic phenomena can be explained within single level, using syntax and, more importantly, the semantics which is the central theme of the GPSG work. In order to analyze syntactic transformations, the GPSG set up various rules such as metarules, lexical and non-lexical ID rules. Unlike classical TG theories, which are inevitably to undergo complex transformational processes, the GPSG has the merits of simplicity in describing syntactic varieties. In addition, we have also seen from the analyses of topicalization that syntax and semantics interact with each other while each has its own domain strictly defined, The research also reveals that the applicability of GPSG theory to Korean language is relatively high if some specific grammatical attributes of Korean language are properly interpreted be forehand. In this regard, it seems safe to say that, in a broad sense, FFP and STMI of GPSG are universal. Further detail study is definitely needed on interpreting some exceptional grammatical phenomena of a certain language in order to make them fit into the formal system of GPSG theory.
