The purpose of this study was to identify the factors affecting family functioning of stroke patients. A descriptive survey research was conducted in which 65 stroke patients and their primary caregivers were conveniently sampled. Data were collected from July to September, 1998 through interviewing using a structured questionnare. The measuring instruments used were Barthel Index by Mahoney and Barthel(15 items), Quality of Relationship Scale by Archbold and Stewart(15 Items), Role Stress of Caregiver Scale by Yang(14 items), Situational Definition Scale by Lee(9 items), Family Hardiness Index by McCubbin, McCubbin. and Thompson(20 items), and Family Adaptability Cohesion Evaluation Scale(FACES-III) by Olson, Portner, and Lavee(20 items). The obtained data were analyzed using percentage, t-test, ANOVA, Duncan test, and Pearson coefficients correlation by SAS/PC program. The results were as follows; 1. Role Stress of Caregiver was not severe and Quality of Relationship was moderate. The level of Situational Definition of primary caregivers was not high but Family Hardiness and Family Functioning were rather high. 2. The following relationships between research variables and demographic characteristics of the primary caregivers of stroke patients were significantly different; occupation of caregiver between Quality of Relationship, occupation of caregiver between Situational Definition, family type between Role Stress, caregiving duration between Family Hardiness, caregiving duration between Family Functioning, and hospitalization days between Family Functioning. 3. The correlations between research variables were as follows; There was positively correlated between patient's ADL and Quality of Relationship. The relationship of the patient's ADL between Role Stress was negatively correlated. Quality of Relationship between Situational Definition, Family Hardiness, and Family Functioning were significantly correlated. The correlation of Situational Definition between Family Hardiness, and Situational Definition between Family Functioning were very high. As a result of these findings, Quality of Relationship, Role Stress, Situational Definition. and Family Hardiness were useful variables for identifying Family Functioning of stroke patients. It is important for the rehabilitation nurse to be knowledgeable about family functioning of stroke patients to promote rehabilitation process.

The purpose of this study was to test the hypothetical model designed to explain nursing students' perceived stress, coping levels, and stress outcomes. This hypothetical model was based on the Kim. Jung Hee(l987)' s stress model and stress-related literature. Exogenous variables were self-efficacy. hardiness. social support. and exercise. Endogenous variables were stress perception. coping levels. and stress outcomes. Empirical data for testing the hypothetical model consisted of 205 nursing students. SAS PC Program and LISREL 8.12a program were used for descriptive statistics and linear structural relationship(LISREL) modeling. The results were as follows. 1) The overall fit of the hypothetical model to the data was good( $x^2$=78.41(p=0.010), $x^2$/ df=1.50. RMSEA=0.05, standardized RMR= 0.05, GFI=0.95, AGFI=0.91, NNFI=0.90, NFI=0.94). 2) The results of statistical testing of the hypotheses were as follows. (1) As expected. self-efficacy had a significant effect on stress perception. But. hardiness. social support, and exercise did not have a significant effect on stress perception. Self-efficacy, hardiness. social support, and exercise explained 12% of the total variance of stress perception. (2) As expected, self-efficacy, hardiness, social support, exercise, and stress perception had a significant effect on coping behavior, Self-efficacy, hardiness, social support, exercise, and stress perception explained 53% of the total variance of coping behavior. (3) As expected, stress perception and coping behavior had a significant effect on stress outcomes. Stress perception and coping behavior explained 84% of the total variance of stress outcomes. In conclusion, the hypothetical model of this study was confirmed in explaining and predicting stress perception, coping levels, and stress outcomes in nursing students. And these findings suggest the need to develop nursing intervention to enhance self-efficacy, hardiness, social support, and exercise to decrease the harmful outcomes of stress.

The purpose of this study was to explain the relationship between smoking status, smoking behavior and hardiness in university students in Gangnung City. The subjects were a convenience sample of 315 students. The data were collected by a questionnaire given to the students between May 22 to June 2, 2000. An instrument developed by Akers & Gang(1996) and translated by Sohn, Jung-Nam(1999) was used in this study to measure definition of smoking, differential reinforcement of smoking and smoking behavior. The differential peer association scale developed Krohn et al.(1982) and translated by Sohn, Jung-Nam(1999), and the hardiness scale developed by Pollock(1984) and translated by Suh, Mun-Sa(1988) were also used. The data were analyzed using the SAS/PC+ Program and included descriptive statistics, t-test, ANOVA, and Spearman correlation coefficients. The results of this study are as follows : 1. The smoking rate for university students was 50.5% of which 44.7% started smoking in high school. 2. The mean score for level of hardiness was $3.14{\pm}0.43$ 3. The mean score for smoking behavior was as follows : 1) The mean score for the neutralizing definition was $2.16{\pm}0.57$ 2) The mean score for the negative definition was $2.37{\pm}0.71$ 3) The mean score for the positive differential reinforcement was $1.89{\pm}0.63$ 4) The mean score for the negative differential reinforcement was $2.96{\pm}0.64$ 5) The mean score for the differential peer association was $2.67{\pm}1.05$ 4. The data showed positive correlations between hardiness and the neutralizing definition(r=.1951, P<.001), between hardiness and the positive differential reinforcement(r=.1128, P<.05), between hardiness and the amount of smoking per day(r=.1452, P<.05) between the neutralizing definition and positive differential reinforcement(r=.4212, P<.0001), between the neutralizing definition and differential peer association(r=.1856, P<.001), between the neutralizing definition and age at smoking initiation(r=.1582, P<.05), between the negative definition and negative differential reinforcement(r=.2985, P<.0001), between the positive differential reinforcement and differential peer association(r=.3451, P<.0001), between positive differential reinforcement and the amount of smoking per day(r=.4431, P<.0001), between differential peer association and the duration of smoking(r=.2789, P<.0001), between differential peer association and the amount of smoking per day(r=.5410, P<.0001), between the duration of smoking and the amount of smoking per day(r=.4245, P<.0001). The data showed negative correlations between the neutralizing definition and the negative definition(r=-.2065, P<.001) between the neutralizing definition and negative differential reinforcement(r=-.3943, P<.0001) between the neutralizing definition and duration of smoking(r=-.1957, P<.05), between the negative definition and positive differential reinforcement(r=-.2093, P<.001), between the negative definition and the amount of smoking per day(r=-.2282, P<.001), between positive differential reinforcement and negative differential reinforcement(r=-.5555, P<.0001) between negative differential reinforcement and differential peer association(r=-.3653, P<.0001), between negative differential reinforcement and the amount of smoking per day(r=-.4570, P<.0001), between the age at smoking initiation and the duration of smoking(r=-.4594, P<.0001).

Warming trends during winter seasons in East Asian regions are expected to accelerate in the future according to the climate projection by the Inter-governmental Panel on Climate Change (IPCC). Warmer winters may affect short-term cold hardiness of deciduous fruit trees, and yet phenological observations are scant compared to long-term climate records in the regions. Dormancy depth, which can be estimated by daily temperature, is expected to serve as a reasonable proxy for physiological tolerance of flowering buds to low temperature in winter. In order to delineate the geographical pattern of short-term cold hardiness in grapevines, a selected dormancy depth model was parameterized for "Campbell Early", the major cultivar in South Korea. Gridded data sets of daily maximum and minimum temperature with a 270m cell spacing ("High Definition Digital Temperature Map", HDDTM) were prepared for the current climatological normal year (1971-2000) based on observations at the 56 Korea Meteorological Administration (KMA) stations and a geospatial interpolation scheme for correcting land surface effects (e.g., land use, topography, and site elevation). To generate relevant datasets for climatological normal years in the future, we combined a 25km-resolution, 2011-2100 temperature projection dataset covering South Korea (under the auspices of the IPCC-SRES A2 scenario) with the 1971-2000 HD-DTM. The dormancy depth model was run with the gridded datasets to estimate geographical pattern of change in the cold-hardiness period (the number of days between endo- and forced dormancy release) across South Korea for the normal years (1971-2000, 2011-2040, 2041-2070, and 2071-2100). Results showed that the cold-hardiness zone with 60 days or longer cold-tolerant period would diminish from 58% of the total land area of South Korea in 1971-2000 to 40% in 2011-2040, 14% in 2041-2070, and less than 3% in 2071-2100. This method can be applied to other deciduous fruit trees for delineating geographical shift of cold-hardiness zone under the projected climate change in the future, thereby providing valuable information for adaptation strategy in fruit industry.

Purpose: The purpose of this study was to identify the factors affecting shiftwork tolerance among nurses and provide basic data, ultimately, in formulating a plan for improving their shiftwork tolerance. Methods: The participants were 317 nurses who were working at three general hospitals in Daejeon and Seoul. Data analyzed t-test, ANOVA, correlation analysis, and regression analysis using SPSS 20.0 program. Results: As for the sub-areas of shiftwork tolerance for the respondents, more than a half of nurses working at shifts suffered from insomnia, felt drowsy, complained of chronic fatigue, and were at the anxious and depressed state. Shiftwork tolerance differed by the daily intake of coffee and exercise. Shiftwork tolerance was significantly positively correlated with sleep-wake habits, hardiness, and flexibility and negatively correlated with a languidity. Regression analysis revealed that shiftwork tolerance was affected by age, sleep-wake habits, languidity, flexibility, and hardiness. Conclusion: To put the results, nurses had shiftwork tolerance affected by sleep-wake habits, languidity, and hardiness. It is therefore necessary to make a scheme for allowing nurses to improve hardiness and flexibility and decrease the languidity with the objective of improving their shiftwork tolerance.

Purpose: This study aimed to identify the effect of job stress, coping behavior, and hardiness on burnout in nurses in the emergency department (ED). Methods: Data were acquired via self-reporting questionnaires from 148 nurses in EDs at one general hospital, four university hospitals, and six hospitals with >200 beds. Data were analyzed using the SPSS 23.0 program through descriptive statistics, t-test, analysis of variance, Pearson's correlation coefficient, and stepwise multiple regression. Results: A statistically significant difference in burnout was observed with respect to the age of the nurses. Burnout was positively correlated with job stress and wishful thinking and detachment, among coping behaviors, and was negatively correlated with hardiness. Job stress and wishful thinking, among coping behaviors, were significant predictors of burnout and were observed in 14.9% of the nurses who experienced burnout. Conclusion: According to our results, job stress was identified as the most significant factor which influenced burnout in ED nurse's. Therefore, it is necessary to develop and implement educational programs for reducing job stress and minimizing the use of wishful thinking as a coping behavior in order to alleviate the burnout in ED nurses.

The purpose of this study was to investigate the factors influencing health promoting lifestyles in undergraduate students thus providing the basic data necessary to establish a health promoting program. The subjects of this study were 392 undergraduate students, living in Seoul, Chung-Buk, and Kangwon, during the period from May 10 to July 15, 2000. The instruments for this study were the health promoting lifestyles scale developed by Bak, Insuk(l995), the hardiness scale by Suh, Yeonok(1995), the social support scale by Su, Moonja(l988), and the perceived health status scale by Lawton et al.(l982). The results of this study are as follows; 1. The average score for health promoting lifestyles was 2.47 on 4 point scale. The health promoting lifestyles categories ‘harmony relationships’(3.08) and ‘sanitary life’(2.97) revealed higher scores, whereas scores for ‘healthy diet’(2.31), ‘exercise ＆ activity’(2.20) and ‘professional health management’(1.48) were lower. 2. The mean score for hardiness, social support and perceived health status was 4.43(on 6 point scale), 2.91(on 4 point scale) and 3.11(on 5 point scale) respectively. 3. There was a statistically significant difference in degree of health promoting lifestyle according to religion(t=2.05, p=0.04) and spending money per month(F=2.98, p=0.03). 4. Health promoting lifestyles showed significant positive correlation with hardiness, social support, and perceived health status. 5. Stepwise multiple regression analysis revealed that the most powerful predictor of health promoting lifestyle was hardiness. Social support and perceived health status have significant effects on health promoting lifestyles. These predictive variables of health promoting lifestyles explained 24% of variance. Finally, the result of this study will provide important factors for the development of a nursing intervention program for the promotion of healthy lifestyles in Korean undergraduate students.

Background and objective: This study was conducted to establish a Plant Hardiness Zone (PHZ) map, investigate the effect of global warming on changes in PHZ, and elucidate the difference in the distribution of evergreen trees between the central and southern region within hardiness Zone 7b in Korea. Methods: Mean annual extreme minimum temperature (EMT) and related temperature fluctuation data for 40 years (1981 to 2020) in each of the meteorological observation points were extracted from the Open MET Data Portal of the Korea Meteorological Administration. Using EMT data from 60 meteorological observation points, PHZs were classified according to temperature range in the USDA Plant Hardiness Zone Map. Changes in PHZs for each decade related to the effects of global warming were analyzed. Temperature fluctuation before and after the day of EMT were analyzed for 4 areas of Seoul, Suwon, Suncheon, and Jinju falling under Zone 7b. For statistical analysis, descriptive statistics and ANOVA were performed using the IBM SPSS 22 Statistics software package. Results: Plant hardiness zones in Korea ranged from 6a to 9b. Over four decades, changes to warmer PHZ occurred in 10 areas, especially in colder ones. Based on the analysis of daily temperature fluctuation, the duration of sub-zero temperatures was at least 2 days in Seoul and Suwon, while daily maximum temperatures were above zero in Suncheon and Jinju before and after EMT day. Conclusion: It was found that the duration of sub-zero temperatures in a given area is an important factor affecting the distribution of evergreen trees in PHZ 7b.
