  • In this paper the extraction method for the best suitable green vegetation area in urban area, Daegu, Korea, was developed using satellite images (1994, 1999, Landsat TM). For this, the GIS overlay analysis of GVI (Green Vegetation Index), SBI (Soil Brightness index), NWI (None-Such wetness Index) was performed to estimate the best suitable green vegetation area. Also, the statistical documents, algorithm and Tasseled-Cap index were used to recognize the change of land cover such as cultivation area, urban area, and damaged area. Through the result of this study, it is possible to monitor the large sized reclamation of land by drainage or damaged area by forest fires. Moreover, information with the change of green vegetation and the status of cultivation by GVI, but also moisture content by percentage by NWI and surface class by SBI can be obtained.

  • Purpose: To develop and test the validity and reliability of the Korean version of PES-NWI measuring nursing work environments in hospitals. Methods: The Korean version of the PES-NWI was developed through forward-backward translation techniques, and revision based on feedback from focus groups. An internal consistency reliability and construct validity using confirmatory factor analysis were conducted using SPSS WIN (16.0) and AMOS (18.0). Survey data were collected from 733 nurses who worked in three acute care hospitals in Seoul, South Korea. Results: The Korean version of PES-NWI showed reliable internal consistency with a Cronbach's alpha for the total scale of .93. Factor loadings of the 29 items on the five subscales ranged from .28 to .85. The five subscales model was validated by confirmatory factor analysis (RMR<.05, CFI >.9). Conclusion: The findings of this study demonstrate that the Korean version of PES-NWI has satisfactory construct validity and reliability to measure nursing work environments of hospitals in Korea.

  • In order to prepare against the unpredictable provocation of nK on NWI, instead of the threat based force enhancement, sufficient capability based force planning is required in consideration to enemy capability, operations environment, and technological development. This thesis proposes a method on how to prioritize the required capabilities of NWI during the process of identifying capabilities and investing on the decided acquisition assets. Ambiguity in deciding the priority is eliminated and detailed planning is possible through instituting relationship of organization, operation and capability, and by designating weight based on the above relationship. This method identify the various operations and required capabilities, classify the order of priority clearly for NWI, when compare to other method of priority decision. Although capability based force planning requires more assets and faces limitations due to budget, this method will provide and efficient decision making procedure through precise prioritization.

  • With the realization of the importance of the NWI, iterated by the Cheonan Ship sink and the YP-Do shelling, this thesis separates the NWI from the peninsula, regarding it separate from the Korea Theater of Operations, and suggests the method to establish NCOE with consideration to the characteristics of separated theater as well as the current situation. Although the NWI holds strategic value, systematical NCOE of surveillance and reconnaissance system, command and control system, and precision strike system is not yet established. Pertaining to this issue, Architecting was utilized to identify improvement measures and of the identified improvement measures, improvement on the "strike on nK hardened artillery sites with K-9 Self-Propelled Artillery in correlations with theater ISR" shows greatly improved strike effects when conducting simulations based on the Operation-Plan Analysis Model. Such a method of NCOE establishment will serve as a standard model for military force building and operation execution system for separated theater operations such as the NWI.

  • Purpose: The purpose of this study was to test the reliability and the validity of the Practice Environment Scale of Nursing Work Index (PES-NWI) scale when applied to Korean psychiatric nurses working in the psychiatric hospital in Korea. Methods: Data from 224 psychiatric nurses working in the 6 psychiatric hospitals in Korea were analyzed using Cronbach's ${\alpha}$, item total correlation, and exploratory factor analysis. Results: The Cronbach's ${\alpha}$ for the 27 items from the PES-NWI were .93, and the item total correlation coefficients ranged from .38 to .64. Six factors which explained 61.2 of variance in the perception of practice environment, emerged; nurse professional role and development, nurse manager ability, leadership, and support of nurses, staffing and resource adequacy, nursing foundation for quality of care, collegial nurse-physician relations, co-worker's ability and qualification. Five derived factors reconstructed, and two factors were renamed. Conclusion: Findings demonstrate that not all but 27 items from PES-NWI is a reliable and valid scale when applied to Korean psychiatric nurses working in Korea. Also findings indicate that Korean psychiatric nurses perceive practice environment differently than American nurses but have some point of similarities with Asian nurses working in the United States.

  • Objectives: To examine whether the nursing practice environment at the hospital-level affects the job satisfaction and turnover intention of hospital nurses. Methods: Among the 11 731 nurses who participated in the Korea Health and Medical Workers' Union's educational program, 5654 responded to our survey. Data from 3096 nurses working in 185 general inpatient wards at 60 hospitals were analyzed using multilevel logistic regression modeling. Results: Having a standardized nursing process (odds ratio [OR], 4.21; p<0.001), adequate nurse staffing (OR, 4.21; p<0.01), and good doctor-nurse relationship (OR, 4.15; p<0.01), which are hospital-level variables based on the Korean General Inpatients Unit Nursing Work Index (KGU-NWI), were significantly related to nurses' job satisfaction. However, no hospital-level variable from the KGU-NWI was significantly related to nurses' turnover intention. Conclusions: Favorable nursing practice environments are associated with job satisfaction among nurses. In particular, having a standardized nursing process, adequate nurse staffing, and good doctor-nurse relationship were found to positively influence nurses' job satisfaction. However, the nursing practice environment was not related to nurses' turnover intention.

  • This study was conducted to utilize as basic information for the construction of conservation and estimation system for Palustrine wetland, which was badly managed and imprudently reclaimed, through the analysis of distribution characteristics and the estimation of conservation value for sample sites (eight wetlands) in rural area. As the result of wetland type classification, these wetlands was classified by 4 types (Permanent freshwater marshes/pools, ponds, Aquaculture ponds, and Seasonally flooded agricultural land) by Ramsar system, 3 types (Emergent Wetland, Aquatic Bed, and Scrub-Shrub Wetland) by NWI (Cowardin) System, 5 types (Farm Pond Depression, Under-flow wetland, Man-made Pond Depression, Abandoned Paddy Fields Wetland, and Reservoir Shore) by National Wetland's Categorical System, and 3 types (Aquatic Bed Wetland, Emergent Wetland, and Forested Wetland) by Lee (2000) System. These results suggest us developing the new type classification system for small Palustrine wetland in Korean rural areas. The score of function assessment (The Modified RAM) for small Palustrine wetlands was high at the wetlands nearby hills and rice paddy fields, and low at those nearby upper fields, which was mainly affected by land-use and vegetation. The functions as 'Flood/Storm Water Storage', 'Runoff Attenuation', 'Water Quality Protection' were resulted by the structural difference of inflow and outlet. Some functions as 'Wetland size', 'Wetland to immediate watershed ratio', 'Presence of boat traffic', 'Maximum water depth', 'Fetch of water's body' of RAM were not appropriate in evaluation of small wetlands in rural area. Which suggest us developing the new function assessment system for small Palustirne wetland in Korean rural areas.

  • Purpose: This study was aimed at (a) describing professional nursing practice environments embedded in nursing care units and (b) examining its relationships to nurses' task motivation. Method: Using the Nursing Work Index Revised (NWI-R) and the Work Preference Inventory (WPI), a descriptive study was conducted with a sample of 320 registered nurses on 26 nursing care units in one University hospital in Korea. Result: Mean scores were 12.9 on a 5-20 score range of an autonomous environment scale, 7.3 on a 3-12 score range of a collaborative environment, and 15.8 on a 7-28 score range of control over nursing practice. Nurses' age, educational level, job position, working period at the hospital and employment status were significantly related to the degree of a professional practice environment. The extent to which a professional practice environment accounted for task motivation was $19.5\%$. Conclusion: There is a certain degree of professionalism in the workplace environment that nurses perceived within the nursing care units. When nurses care for patients, the degree of task motivation depends on the work environment supporting the professional nursing practice.

  • Purpose: The purpose of this study was to identify the influence of nursing practice environment, compassion fatigue and compassion satisfaction on burnout among clinical nurses in Korea. Methods: A descriptive crosssectional study was conducted. The sample consisted of 210 clinical nurses from three tertiary hospitals located in Seoul. Measurement instruments included the Korean version of the Practice Environment Scale of Nursing Work Index (K-PES-NWI) and Stamm's professional quality of life (ProQOL). Descriptive statistics, t-test, ANOVA, correlation analysis, and multiple regression were used to analyze the data. Results: Nursing practice environment had moderate negative influence on burnout (r=-.38, p<.001). Compassion fatigue had strong positive influence on burnout (r=.50, p<.001), while compassion satisfaction had strong negative influence on burnout (r=-.61, p<.001). The regression model explained 63% of variance of burnout and the compassion satisfaction was the most influencing factor for nurses' burnout. Conclusion: This study identified nursing practice environment, compassion fatigue and compassion satisfaction as influencing factors for nurses' burnout. Strategies to decrease compassion fatigue, enhance compassion satisfaction and create better nursing practice environment are recommended to decrease nurses' burnout.
