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

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.

This study is focused on understanding the relation between patient flow and nursing service. Investigated the number of patient and nurse who were under nursing service, after looking into the nursing list concerning the patient who were hospitalized at the mixed surgery unit and the sole surgery unit among the surgery unit in H hospital, one of Third Medical Institution in Seoul, from 1 January to 30 June, 2002. The result of study are as follows: 1. The mixed surgery unit is three times more than the sole surgery unit concerning the absolute number of admission and discharge's average in a day. 2. The factor of administration (transferring a room and unit, admission and discharge) and medical treatment (surgery), all of them that the mixed surgery unit is more than the sole surgery unit. This difference had the meaning statistically. 3. The number of patient per nurse is not different between the mixed surgery unit and sole surgery unit, however in case of the number of patient caused by movement factor, the mixed surgery unit is more than the sole surgery unit in a day and month. Consequently, it suggests to examine the working plan flexibly in a day and month with considering the administration factor such as movement, as thinking over the manpower arrangement in the unit with having the limited manpower.
