박현수,김경희,조양자,서인수 대한감염학회 1989 감염 Vol.21 No.2

In order to evaluate the possibility that facal E. coli might serve as a reservoir of β-lactamases for Haemophilus influenzae, Neisseria gonorrhoeae, or other members of the Family Enterbacteriaceae, 135 fecal E. coli isolates from Korean children uder two years of age were tested for resistance to ampicillin (??) and for β-lactamases activity. ?? was found in 115(85%) strains of E. coli tested. Of the 115 ?? E. coli, 87(76%) were β-lactamases producers. High rates of ?? and β-lactamases activity were found uniformly in various pathogenic types of E. coli. Our observations raise questions concerning the importance of fecal E. coli in the prevalance of β-lactamase producing bacteria in the community. Fecal E. coli of Korean children may be important in the epidemiology of β-lactamases producing pathogens in humans.

Human sparganosois was reported more than 100 cases in Korean population. However no case reported yet in Korea as a patient was infected by sparganum from other geographical area, such as Thailand. The case we are reported here is a 38 year-old Korean male who had been suffered from mass being a small, round and soft consistance in upper portion of his right thigh. The patients stated that he had an opportunity to eat living snake in Bangkok, Thailand during trip. As therapy praziquantel (75㎎/㎏/day) was given p.o. for 14 days, but in vain to cure. Following medical treatment, surgical exicision was performed to remove a alive, soft, whitish-milky, mobile and elongated sparganum. Serlogical test by micro-ELISA for sparganum-specific antibody revealed a high serum antibody level of absorbance 0.67 (positive criterion: absorbance 0.22).

Peroxidase(EC1.11.1.7) was partially purified from Korean radish by CM-Sepharose CL-6B, gel filteration on Sephacryl S-200 and DEAE-Sephacel column chromatography. The molecular weight of the enzyme was estimated to be about 34,000 by gel filtration on Sephacryl S-200. The optimal conditions for the enzyme reaction were pH6.5 and temperature of 65℃.The enzyme was very stable by heating at 60℃ for 30 munutes, while almost 91.2% of enzyme zctivity was lost by heating at 75℃ for 30 minutes. Kivetic studies indicated a K?? of 0.40mM for hydrogen peroxide at fixed phenol concentration, and a K?? of 67mM for phenol at a fixed hydrogen peroxide concentration . The peroxidase activity was enhanced by addition of pb???? and Mg????, respectively, meanwhile Mn??, Ca??,Fe??, K??, and Ag?? inhibited the enzyme significantly.

purpose: This study was conducted to describe qualitatively the entities of nurse's experiences in general hospitals and to suggest basic data guiding research on developing Standards of clinical nursing practice in Korea. Method: Fourteen nurses working at general hospitals with over 300 beds in Seoul were interviewed in-depth until saturation using tape-recorders and transcription. Result: The central theme of clinical nursing practice experienced by subjects was "being with clients" that means accepting client's personal character, solving client's needs and providing client-centered nursing. A also "being with clients" was felt to be the responsibility of nurses which was learned from their nursing schools. The nursing strategies performed in order to be with patients were proving skillful nursing techniques, accepting, educating, emotional support, advocating, and self-reflecting, the subjects experienced somewhat problematic affects such as difficulties in interpersonal relationship, work overload, negative image of nursing, deficit of self-confidence for nursing actions, poor working conditions, and unfair treatment. Nurses at the hospital practiced with pride when they felt that they were accepted by clients. Conclusion: Further research is needed to analysis problems in clinical practice and the comparison of nurses' experiences of clinical practice, with nurses' experiences in various settings.

This study has been conducted to offer as a reference material for follow-up research by other handball related researchers in this field study about handball. Knowing that the decision of the referees play a big role in the result of the game, we hope this study pave the way for future researchers, To achieve these goals, this study was selected with professional and amateur handball players as control group. The data were analized by One-way ANOVA and Multful regression using SPSS 11.0 for windows, This study resulted as the following : These decision of the referees differed according to the sex of the handball players. Female handball players showed a more positive attitude toward the referees decisions, Also, female and male handball players all thought the referees decision affect the result of the game but in particular, female players thought the referees were stricter than to male players, Meanwhile, according to the result of the survey of the relationship between the players awareness and experience, it turns out that the quality of the game resulted from the quality of the referees, After analyzing the awareness of players, tit was found that a crucial amount of the players consciousness was affected by the attitude of the referees. In this sense, handball players tend to become overly sensitive to the referees that, handball players. The analysis also represents the players consciousness to the referees but at the same time no findings proved that there is a certain impact on the result of the game. According to the results of this surrey, the handball players showed little confidence for the referees and this affects the result of the game. However when it comes to the impact of the referees on the game, the decision of the referees have consistency in making decisions of the game, and this has no actual affect on the result of the game. The reason these results come out is because it's a characteristic of handball but further analysis and theories should be made.

The purpose of this study was to evaluate the effect of sociodramatic play training on children's learning readiness development and to find effective teaching strategies of sociodramatic play for 4∼5 year-olders. The subjects were 30 children attending a full time day care center. They were divided into experiment group and control one according to their age, sex, and IQ scores. Experiment group had 12 sociodramatic play training sessions. There training sessions were held in a week and each session took about one hour. The test used in this study was Developmental Test of Learning Readiness for Preschoolers developed by KEDI(1987), and t-test was used for the analysis of data. The results of this study were as follows: 1. Experiment group was improved significantly more than control group in the total score of learning readiness development test. 2. Experiment group was improved significantly more than control group in the scores of motor coordination area and in the comprehension area. 3. Children showed preference for particular social roles such as doctor or buyer. The more training sessions were, the more spontaneous were children. Older children showed more leadership than younger ones in sociodramatic play. As play session proceded, children became involved into play more quickly and actively. Teacher's affective intervention brought positive effects on children's active participation. Summary and discussion were followed.

Urine certified reference material(CRM) has been developed to help clinical labolatories control analytical accuracy. Two levels of freeze-dried urine were prepared. The low level CRM was made from normal urine and the abnormal level CRM was prepared by spiking th normal urine with As, Cd, Cr, Cu, Hg, Ni and Pb. Urine reference materials were analyzed by graphite furnace atomic absorption spectrometry(GFAAS) and inductively coupled plasma mass spectrometry(ICP-MS). Analyte elements were separated from matrix elements by using ion exchange resin and hydride generation. Isotope dilution method was employed to enhance analytical accuracy. Round robin test results are also presented which were carried out with 5 clinical laboratories.

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

沈慶久,朴相獻,徐炳基 成均館大學校 科學技術硏究所 1987 論文集 Vol.38 No.2

Pollen morphology, sculpturing, and structure are useful in taxonomic studies from the family to the cultivar level. Scanning electron microscopy (SEM) studies on pollen morphology have proven to be a useful plant identification tool for taxonomists and horticulturist. Pollen grains of 5 Hibiscus moscheutos 'Southern belle' unnamed were studied. This study was conducted to observe pollen characters, and to investigate possibility of classification among cultivars. The results obtained were as follows. Pollen grains were characteristically monad and circular, sculpturing patterns were clavate in the light-pink color, others are echinate, and aperture were periporate. The diameter of pollen were large in the light-pink color and white color, and height of spines appeared small. Number of spines of pink color, light-color, and white color were more than that of the others. Number of aperture had no significant differeence each other, and number of pore area were plenty in flower-pink color and pink color. Morphological and structural characteristics of pollen may serve as an aid in the taxonomic identification of cultivars in Common Rose Mallow.
