Purpose: This study was to provide preliminary data for degree of self-leadership in pregnant women. Method: Participants were 148 pregnant women who visited 2 university hospitals in Taegu city. Data collection was done from April 16 to May 22, 2005 by self administered questionnaires. Results: The mean score for self-leadership of pregnant women was 3.27 and the thought self-leadership of subconcept was the highest score. The highest mean score in self-leadership was found in 'When I'm faced with a problem during the pregnancy period' and 'I tend to look for the opportunity it contains rather than drawbacks'. The lowest mean score in self-leadership was found in 'I often practice health management before I actually do them'. There was the highest positive correlation between self-leadership and natural reward. Conclusion: This study had highest positive correlation between self-leadership and natural reward. Considering this, self-leadership is an effective nursing strategy to promote natural reward. Further studies are necessary to identify the level of self-leadership in pregnant women.

Traditional CVP (Cost-Volume-Profit) analysis employs linear cost and revenue functions within some specified time period and range of operations. Therefore CVP analysis is assumption of constant labor productivity. The use of linear cost functions implicity assumes, among other things, that firm's labor force is either a homogenous group or a collection homogenous subgroups in a constant mix, and that total production changes in a linear fashion through appropriate increase or decrease of seemingly interchangeable labor unit. But productivity rates in many firms are known to change with additional manufacturing experience in employee skill. Learning curve is intended to subsume the effects of all these resources of productivity. This learning phenomenon is quantifiable in the form of a learning curve, or manufacturing progress function. The purpose d this study is to show how alternative assumptions regarding a firm's labor force may be utilize by integrating conventional CVP analysis with learning curve theory, Explicit consideration of the effect of learning should substantially enrich CVP analysis and improve its use as a tool for planning and control of industry.

Soil samples were collected in thirteen Manitoba boreal forest sites. Spatial distribution of chytrids from diverse boreal forest microhabitats was investigated by baiting with jack pine pollen. After baiting, the pollen was surveyed for chytrids for 8 ten day period and individual species were counted. Total infestations of pollen by chytrids ranged from 5.8% to 90.2% from various soils. Each site with high infestation was characterized by litter with high needle content while mineral soil or soil with limited organic matter yielded low levels of pollen infestation. Species diversity tended to be higher in soils with higher pollen infestation and lower in soils with lower pollen infestation. Lower diversity was generally observed in mineral soils or soils with a limited organic horizon comprised, in part, of broad leaf litter. Based on coefficients of association and species in common among species across the collection sites, it was possible to relate dominant species assemblages in site groups. These species assemblages in the site groups suggest that the chytrids are distributed by litter and soil types. It can be concluded that the substratum characteristics of litter types and availability of litter may be important in describing chytrid distribution in boreal forest sites.

Purpose: The purpose of this study is to identify and to investigate the nursing organizational culture. Method: A descriptive correlational study was conducted with convenience sample of 448 staff nurses who were working for six general hospitals located in Seoul, Province of Gyeonggi and Province of Chung-cheong. The period of data collection took over 5 months between August and December. Organization Culture Questionnaire developed by Lee (2001) were used to measure nursing organizational culture. Collected data were analysed on SPSS Win 12.0. Result: The meta culture of the nursing organizations was the conservative culture. The cultural pattern of nursing organizations was classified into three patterns which were conservative-dominant culture, symmetric culture and innovative-task culture. Conclusions: The meta culture of the nursing organizations was the conservative culture. But conservative culture decreased nurses' outcomes. Therefore the nurse manager should develop a symmetric organizational culture including four types of culture than dominant culture of one type.

This study developed the learning ability-based smart education program. The effectiveness of the developed materials was investigated using the quantitative-qualitative mixed method, and the process and results of the investigation are as follows. The quantitative investigation was conducted using the non-equivalent pretest-posttest design, in which the smart education method was applied to the experimental group, while the conventional education method was applied to the control group to analyze students' creative problem-solving potential, task concentration, and the variables required for the learning activity. The results showed significantly higher performance in the experimental group over the control group. Regarding data collection in the qualitative investigation, an analysis of the class from the instructor and class consultation logs from the class analyst were collected; the comments on the experience of each class period were collected from students. The results of the analysis of the data suggest that the perception of smart education improved for the instructor, class analyst, and learners as the course progressed.

Polyethylene glycols (PEGs; 400, 600, and 1000) were used to study the molecular weight (MW) permeability dependence in the rat ileal mucosa. Absorption of the PEGs was measured by following their recirculation perfusion over a 3 hr collection period. HPLC methods were used to separate and quantitate the individual oligomers present in the solution of PEGs mixtures (MW range 330 to 1 1 22 D). In the range studied, a distinct molecular weight cutoff was not identified. Corrected for the length of ileum used in the study, over the molecular weight range 330 to 1122 D, the apparent permeability $(P_{app)$ of PEG ranged from $3.2\pm0.06\times10_{-5} cm/sec(mean\pmSEM, n=7)\; to\; 0.1\pm0.02\times10^{-5} cm/sec.$ Also, it was observed that the apparent permeability was inversely proportional to approximately $MW^{2.4}$.

Although scholars have been using qualitative research commonly since 1990 in Korea, discussions on the criteria for the quality of qualitative research have been rare. The purpose of this paper was to analyze the trends of qualitative research methodology in Family Studies, and critically examine qualitative research articles published in the three most prominent journals in the field of family studies. The three journals were Journal of Korean Home Management Association, Journal of the Korean Home Economics Association, and Journal of Family Relations. During the period from 1998 to 2003, twenty seven published articles were identified as qualitative research articles from the three journals. Qualitative research in family studies had a wide variety of purposes, but the articles shared similar characteristics: the main goal was to understand the nature of the research participants' experiences and perspectives. The common data collection techniques were in-depth interview, journal writing, and document analysis. Also, all research articles had applied various techniques to data analysis such as grounded theory, or van Manen's method. This article also discussed the usefulness of qualitative research methodology in broadening and deepening the knowledge body in Korean Family Studies.

The diverter system is a key component in achieving a high accuracy liquid flow rate standard using a static gravimetric system with a flying start and stop method. The diverter is a moving device used to direct flow alternately along its normal course(by pass) or towards the weighing tank. The time needed for collection into the weighing tank is measured using a timer. So it is important to the diversion period is sufficiently fast and triggering point of timer which is determined the filling time. On this studies show that uncertainty of diverter system for changing diversion speed and triggering point was estimated in accordance with Guide to The Expression of Uncertainty in Measurement(ISO).
