  • 본 시험은 휴면 정도 및 탄소 함량이 사과나무의 과대지 내동성에 미치는 영향을 밝히고자 실시하였다. 시험재료는 M.26과 M.9에 접목된 성목기 '후지' 사과나무의 과대지였다. 과대지의 휴면 정도는 자발휴면기(1월말), 자발휴면 타파 초기(2월초), 자발휴면 타파 후기(2월말), 발아기(3월말) 및 개화기(4월말)로 구분 하였다. 저온처리 범위는 $0^{\circ}C$부터 $-40^{\circ}C$ 사이였다. 탄소 함량의 차이에 따른 내동성은 갈색무늬병에 의해 낙엽이 심하게 발생한 '후지'/M.9 사과나무(낙엽구)와 과다결실에 의해 평균 신초장이 20cm 이하였던 '후지'/M.9 사과나무(수세가 약한 시험구)를 대상으로 조사하였다. 결과를 살펴보면, 과대지의 내동성은 자발휴면 타파 후에 약해졌다. M.9와 M.26에 접목된 '후지' 사과나무 과대지의 탄소 함량의 차이는 없었으며, M.9과 M.26 대목에 접목한 사과나무 과대지의 내동성 차이는 없었다. 건전구에 비해 낙엽구의 과대지는 C/N율이 낮았고, 수세가 약한 시험구는 탄소 함량이 낮았다. 이러한 결과에 의해 낙엽구와 수세가 약한 시험구의 내동성은 건전구보다 약하였다.

  • 본 연구는 직무스트레스와 개인적 자원(강인성, 낙관성)이 아동상담자의 소진 및 직무열의에 미치는 영향을 알아보고자 하였다. 이를 위해, 아동 대상 심리치료를 하는 아동상담자 171명에 대해 설문조사를 실시하였다. 수집된 자료는 상관분석 및 위계적 다중회귀 분석방법을 통해 분석하였다. 그 결과, 직무스트레스와 개인적 자원은 소진 및 직무열의와 상관관계를 나타냈는데, 특히 직무스트레스는 소진과, 개인적 자원은 직무열의와 더 밀접한 상관을 보였다. 직무스트레스는 소진을 높이는 것으로 나타났으며, 개인적 자원으로서 강인성은 소진을 감소시키는 것으로 나타났다. 직무열의와 관련해서는 강인성과 낙관성이 직무스트레스에 비해 상대적인 영향력이 컸다. 따라서 강인성이나 낙관성과 같은 심리적 자원을 가진 아동상담자는 소진을 덜 느끼고 자신의 일에 더 많이 헌신하며, 몰두한다는 것을 알 수 있다. 본 연구결과를 바탕으로 아동상담자에 대한 실천적 함의를 논하였다.

  • Purpose: The purpose of this study was to identify predictors of depression and quality of life among older adults with osteoarthritis. The predictors included in the model were the client's characteristics(age, pain, disease duration, ADLs), personal resources(hardiness, self-care agency and family support), and depression. Method: 150 subjects who were older than 65 years and had diagnosis of osteoarthritis participated in the study. To answer the research questions, descriptive analysis, Pearson correlation, and hierarchical multiple regression were utilized using SPSS WIN program. Result: Older adults who were younger and had lower levels of pain and dependency on ADLs, and higher levels of self care agency and hardiness reported lower levels of depression($R^2=0.517$). Older adults who had lower levels of depression, pain, and dependency on ADLs, higher levels of family support and hardiness, and who are younger reported higher levels of quality of life($R^2=0.084$). Conclusion: Based on the findings of this study, development of nursing intervention program including pain reduction, enhancing ADL abilities and personal resources (hardiness, family support) can be suggested. Further study is needed to increase the ability of generalization of the study findings to the broader population.

  • The purposes of this study are to delineate a profile of the state of a stroke patient's adaptation at 3 months after hospitalization and to explore the relationship between the level of adaptation and the variables which influence the adaptation of hemiplegic patients. To these ends, theoretical framework was derived basically from the stress adaptation model. The basic assumption underlying the level of adaptation is influenced by the presenting focal, contextual and residual stimuli. This group of stimuli is further operationalized and represented by a perception of stress. which is the perceived effect of the disability and by the mediating variables such as sociodemographic factors as an external conditioning variables and perceived social support and hardiness personality characteristics as an internal intervening variables. The dependent varibales in this study is the level of physical, psychological and social adaptation and is hypothesized to be a function of the interaction between 3 sets of variables namely, the perceived disability effect, external conditioning variables and internal intevening varibles. A total of fourty three subjects from 3 general hospitals in Seoul were observed and interviewed with the aid of 7 structured instruments. The data were collected twice on each subject : first at the pre-discharge period arid at 3 months post-discharge from hospital for the second time. The study was carried out for the period from February to August, 1988. The instruments used for the study include 4 existing scales and 3 scales developed by the researcher for this study. They are : 1) The ADL dependency scale and the scale of the clinical physical functions for the assessment of physical adaptation. 2) the SDS(self report of depression) to measure the level of psychological adaptation. 3) The scale for the amount of social activities for the measurement of the level of social adaptation. 4) The scale for the perceived effect of disability for the measurement of the focal stimuli. 5) The health related hardiness scale and the perceived interpersonal support self evaluation list(ISEL) for the measurement of the hardiness personality character and the perceived social support. The data obtained were analyzed using percentage, oneway ANOVA, Pearson coefficients correlation and stepwise multiple regression. The findings provide valuable information about the present level of physical adaptation at 3 months after discharge. The patient revealed a decreased ADL dependency and lowered limitation of physical function as compared with pre - discharge state. Psycholcgically, the average degree of depression at follow up was within normal range of depression. Socially, the amount of social activities was very low. The one way ANOVA and the correlational analysis revealed the relationship between the 3 sets of variables and the adaptation level as follows : 1) The perceived disability effect was related to the degree of the depression and the amount of social activities but was not related to the physical adaptation. 2) Among the sociodemographic variables, sex and education were related to the difference of ADL dependency and the change of physical function. These factors indicate that women more than men and educated more than the less educated were found more independent. The education was also related to the degree of depression suggesting that the higher the educational level, the more well adapted the patients were both physically and psychologically. Age, marital status and job state were not found to be related to the patient's adaptation level. 3) Among the internal intervening variables, the health related hardiness characteristic was related to the differences of ADL dependency, physical functions and the social activities, indicating that the higher the hardiness character the higher the level of physical and social adaptation. 4) The perceived social support, another internal intervening variable, was related to the degree of depression and the social activities. This data suggest that the higher the perception of social support, the better adapted the patients were psychogically and socially. In summarizing the results of the correlational analysis, the level of physical adaptation was influenced by sex, the years of education and the hardiness character. The level of psychological adaptation was influenced by the years of education, the perceived disability effect and the perceived social support. And the level of social adaptation was influenced by the perceived disability effect, the hardiness character and the perceived social support. The stepwise multiple regression analysis shows findings as follows : 1) The most important factor to explain the difference of ADL dependency was sex, indicating females were more independent than males. 2) The most important factor to explain the difference of physical function and the degree of depression was the patient's education level. 3) The strongest explaining factor for the amount of social activities was perceived self esteem(one of the subconcepts of perceived social support). Thus the most important factors influencing the level of adaptation were found to be sex, education, the hardiness character and self esteem. From the above findings, the significance of this study can be delineated as follows : 1) Corroboration of the assumed relationship between the various variables and the adaptation level as suggested in the conceptual model. 2) Support for the feasibility of the cognitive approach for nursing intervention such as hardness character training, counselling and teaching for self-care in the chronic patients.

  • To determine factors affecting self-care behavior of diabetics, the relationships of hardiness, family support, demographic and medical variables to self-care behavior were investigated in 180 samples with non-insulin dependent diabetes mellitus. In stepwise multiple regression analysis, 26.76% of the variance in self-care behavior was accounted for by family support(15.52%), age(7.76%), and clinical history (2.07%). To compare the magnitude of predictor's significance by gender, stepwise multiple regression was conducted seperatively by gender group. In the male sample 25.22% of the variance in self-care behavior was accounted for by family support, age, and challenge. In the female sample family support, age, and committment were significant predictors in self-care behavior with 28.82% of the variance. The results highlight the value of family support in self-care behavior in diabetics regardless of gender difference. According to the finding of this study, family support is the most significant predictor of self-care behavior in NIDDM. This implicates that in future diabetic care, a family member should be encouraged to participate in the patient education process. Also as hardiness is not supported by a unidimensional construct, more empirical studies are recommended to differentiate the conceptual traits for the three subconcepts of hardiness.
