The purpose of this study is to understand the vegetation structure and ecological characteristics of the coastal forest Pinus thunbergii community in Busan Metropolitan City (BMC) and to establish reference information for the management of the coastal forest in BMC in the future. We set up 97 plots with an area of $100m^2$ each for the analysis and investigation of the vegetation characteristics. The analysis using the TWINSPAN and DCA techniques found seven community groups: Pinus thunbergii-Quercus aliena community, Pinus thunbergii-Eurya japonica(1) community, Pinus thunbergii-Eurya japonica(2) community, Pinus thunbergii-Quercus serrata community, Pinus thunbergii-Camellia japonica(1) community, Pinus thunbergii-Camellia japonica(2) community, and Pinus thunbergii-Eurya japonica-Camellia japonica community. According to the analysis of vegetation structure, Pinus thunbergii was a main dominant species at the canopy layer in all sites while Eurya japonica and Camellia japonica were dominant species at the understory layer. Pinus thunbergii-Quercus serrata community is predicted in the forest succession because of the competition between Pinus thunbergii and Quercus serrata in the canopy layer and the understory layer. As such, it is necessary to observe changes by continually monitoring this community. Tree species with strong salinity tolerance, including Pinus thunbergii, have formed community groups because of the environmental characteristics of coastal forests, strong with salinity tolerance species are forming community groups. Therefore, all community groups except for the Pinus thunbergii-Quercus serrata community will maintain the current vegetation structure unless drastic environmental changes occur.

This study examined the relationship between professional self-concept, interpersonal relationship, coping, and clinical practice satisfaction of nursing college students. This was a descriptive study. The survey participants were 355 students in M city and I city. The data were collected from May 29 to June 16, 2017 and self-report questionnaires, including the Professional Self-concept Scale, Interpersonal Relationship Scale, Coping Scale, and Clinical Practice Satisfaction Scale. The data were analyzed by descriptive statistics, independent-samples t-test, ANOVA, and stepwise multiple regression. Professional self-concept showed significant differences according to religion, income, and school records. Interpersonal relationships showed significant differences according to gender, income, and school records. Coping showed significant differences according to the school records. Professional self-concept had a statistically positive correlation with interpersonal relationship, clinical practice satisfaction, and approach coping. Stepwise multiple regression analysis showed that the predictor of professional self-concept was interpersonal relationships, approach coping, religion, school records, and avoidant coping, which accounted for 45.2% of the variance. These results highlight the need for enhancement programs of nursing college students' professional self-concept that consider their interpersonal relationships, coping, religion, and school records.

To understand the development mechanism of the aerosols in the surface boundary layer, the variation in the aerosol number concentration due to the divergence and convergence of the wind fields was investigated. The aerosol number concentration was measured in the size ranges of $0.3{\sim}10.0{\mu}m$ using a laser particle counter(LPC) from 0000 LST on 03 Feb. to 0600 LST on 07 Feb. 2004 at Mokpo in Korea during snowfall. The Velocity Azimuth Display(VAD) technique was used to retrieve the radar wind fields such as the horizontal wind field, divergence, and deformations including the vertical air velocity from a single Doppler radar. As a result, the distribution of the aerosol number concentration is apparently different for particles larger than $1{\mu}m$ during snowfall, and it has a tendency to increase at the beginning of the snowfall. The increase and decrease in the aerosol concentration due to the convergence and divergence of the wind fields corresponded to the particles with diameters greater than $1{\mu}m$. It is found that the fluctuations in the aerosol number concentration are well correlated with the development and dissipation of snowfall radar echoes due to the convergence and divergence of horizontal wind fields near the surface boundary layer in the inland during the snowfall.

Purposes : This study was conducted to examine nursing effects after using a new method of nasogastric tube feeding with recycled PETE bottle making use of gravity, and to compare with those of bolus method using syringe and pressure. Methods : The data collected from patients with nasogastric tube feeding more than a week at an internal medicine unit of C university hospital located in G-city from January 1st, 1998 through June 30th, 2000. For this nonequivalent control group posttest non-synchronized design, 28 patients were assigned to an experimental group and 35 patients to a control group. The homogeneity of two groups and the dependent variables were tested with use of $x^2-test$ and t-test. Results : The duration of hemostatic use was significantly shorter in the experimental group than control group(t=2.63, p=0.02). Also, the patients with PETE bottle feeding had a lower cost of material(t=3.51, p=0.01) and a lower rate of the time of direct nursing care(t=2.44, p=0.04) than those of control group. But, there was no significant difference between two groups in the length of hospital stay. Conclusion : This results indicates that nasogastric tube feeding with PETE bottle is superior to nasogastric tube feeding with syringe. This findings gave us an evidence to enhance nursing effectiveness in clinical setting.
