Purpose: The study is to investigate the effect of communication and self-leadership on nursing performance. Methods: The subjects of study were composed of 358 nurses at a G city university hospital, tested with structured questionnaire from September 15 to 30, 2010. The collected data were analyzed with ANOVA, Pearson's correlation coefficients and multiple regression analysis. Results: The level of communication, self-leadership, and nursing performance was 3.37, 3.38 and 3.70 respectively in average. The variables showing significant difference in communication were as follows: age, marital status, religious status, education, monthly income, work department and work experience. Also, the variables in nursing performance were as follows: age, marital status, religious status, education, education, monthly income, position, working department and work experience. Communication, self-leadership and nursing performance of nurse showed significant positive correlation. Nursing performance was positively correlated with monthly income, when it exceeded 2.01 million won, career experience and self-leadership (p<.001). These variables explained 53.7% of the regression model. Conclusion: Since monthly income, work experience, communication and self-leadership have positive effect on nursing performance, an effective strategy is required to improve self-leadership and nurse's communication.

Climate is one of most important environmental factors on the forest ecosystem. This study was conducted to analyze the characteristics of meteorological factors in the forest area and weather stations from July 2015 to June 2016 in Cheuncheon and Hongcheon of Kangwon Province in Korea. The HOBO data logger was installed for meteorological analysis in forests area (site 1 and site 2). The meteorological data from the HOBO data logger compared with meteorological data of the weather station. The meteorological data used for the analysis was monthly mean temperature ($^{\circ}C$), monthly mean minimum temperature ($^{\circ}C$), monthly mean maximum average temperature ($^{\circ}C$), and monthly mean relative humidity (%). As a result of this study, the mean temperature ($^{\circ}C$) of forest area was relatively lower than weather station which is the outside the forest area, and the mean maximum temperature ($^{\circ}C$) of weather station was relatively higher than that of forest area. The mean relative humidity (%) was higher in forest area than weather station.

This study is designed to understand demographic characteristics, store selection factors, difference in preferred stores which are considered to be related to store selection behaviors for clothes by college students in Yanbian, China. Questionnaire was used for measurement tools to study the subject of the thesis. Questions used for the evaluation criteria for store selection were primarily based on those previously used by the other researchers with some revision and supplementation. Each question was rated in 5 point scale, where 1 means 'not at all' and 5 means 'definitely'. A total of 50 copies of the questionnaire was passed out to college students in Yanbian from March 20 to March 25, 2001, for the preliminary study. The main study was conducted against 450 college students from May 17 to June 5, 2001 The data for the study were analyzed using SAS PC program for frequency distribution, percentage, 1 -test, and one way ANOVA. A significant difference was showed in the preferred stores between male and female students. In total, underground markets were preferred most with 41.6%, followed by markets with 40.3%. A significant difference was showed among groups regarding preferred stores based on an average monthly income, monthly expense on clothing. Three areas of 'product price', 'display and mood of the store' and 'royal store' showed a significant difference in terms of selecting stores based on an average monthly income. A significant difference was showed in only one areas(brand awareness) in selecting stores based on monthly clothing expense.

To investigate conditions for the survival and growth of Dungeness crab zoeae in situ, spatial and monthly changes of sea surface temperature (SST), sea surface salinity (SSS), Chlorophyll ${\alpha}$ (Chl ${\alpha}$), and zooplankton biomass were measured in four transects: upper Chatham, Icy Strait, Cross Sound, and Icy Point in southeastern Alaska from May to September, 1997-2004. Monthly mean SST was coldest in May, increased throughout the summer months, and decreased in September. SST was coldest in the Cross Sound transect, intermediate in the upper Chatham and Icy Strait transects, and warmest in the Icy Point transect. SSS of northern stations in the upper Chatham and Icy Strait transects decreased throughout the summer months and increased in September, while that of other transects did not vary. Monthly mean Chl ${\alpha}$ was highest in May and decreased thereafter. Chl ${\alpha}$ in the upper Chatham and Icy Strait transects were relatively higher from May through September than those in the Cross Sound and Icy Point transects. Mean zooplankton biomass was highest in the Icy Strait transect in May and lowest in the Icy Point transect in September. This research suggests that oceanographic conditions during the season of Dungeness crab zoeae in southeastern Alaska may not constrain the survival and growth of Dungeness crab zoeae.

Disaggregation model has recently become a major technique in the field of synthetic generation and the model is possibly one of the most widely acepted tools in stochastic hydrology. The application of disaggregation model is evaluated with the streamflow data at the Waegwan and Hyunpung stage gaugin station on the main stem of the Nakdong River. The disaggregation process of annual streamflow data and the method of parameter estimation for the model is reviewed and the statistical analysis of the generated monthly streamflows such as a computation of moment estimation of covariance and correlogram analysis is made. The results, disaggregated monthly streamflow, obtained by Disaggregation Basic Model for single site are compared with the historical streamflow data and also with the other model, Thomas-Fiering Model. The generated monthly streamflow data by two models have been investigated and verified by comparision of mean and standard deviation between the historical and generated data.

In this paper, I studied about historical seasonal subdivision system and a theory of traditional monthly order, which was used for so long from Koryo dynasty to the late of Choseon dynasty in Korean histoy. Especially, I took note of the fact that there used the table of solar terms and meteorological observation what we called the table of Kihoo-pyo in the historical Sunmyung-calendar and the Soosi-calendar during the Koryo dynasty. This table of Kihoo was developed for explaining meteorological change during a year at that time. Here are largely four elements related meteorological nature : the first is the list of 24 solar terms, and the second is 12 monthly seasonal terms and 12 monthly central terms, the third is about four right hexagon based I-ching, the fourth is 72 meteorological observations called 72-hoo. Among them, the 72-hoo system is important to know how premodern people observed natural materials including animals and plants, weather, climate about meteorological phenomena according to the seasonal change or solar terms' change during a year. I argued in this article to need developing modern new table of Kihoo system like that, in order to show common people to recognize annual meteorological change more easy and clear. I also argued to need a distinct definition of meteorological seasons from a view point of modern meteorology.
