  • The relationships among self efficacy, depression and coping with cancer were examined in 194 outpatients who had received a diagnosis of cancer. The sample for this descriptive correlational study consisted of people who were at least 19 years old and had been treated for cancer at 6 hospital in Seoul. Data were collected using a self-report questionnaire. The results of this study are as follows: 1. People who attributed cancer to heredity/family showed the highest mean score of self efficacy. People who attributed cancer to smoking showed the highest mean score of depression. and coping. 2. There were significant differences between causal attribution and depression and between causal attribution and coping. 3. There was a negative correlation between self-efficacy and depression(r=-.301, p= .000), whereas there was a positive correlation between self-efficacy and coping (r=.195, 0=.006). Finally, it is evident that identifying clear perceived causes, self-efficacy, depression and coping in patients with cancer continues to challenge researchers. Based upon this study, it is recommended that future research have a longitudinal design that allows for the identification of changes in perception, emotion and coping and, possibly, different relationships over time.

  • Purpose: The purpose of the study was to meta-analyze the relationships of major concepts, which were made by synthesizing similar explanatory variables into more comprehensive concepts, to hope. Method: The relevant researches from Jan 1980 to Dec 2003, performed in adults or adult patients, were collected. Using the SAS program, meta-analysis were done with the input data of the number of subjects, the correlation coefficients provided from most of the studies or a few transformed correlation coefficients from F value. In order to get the analysis to be done in homogeneous status of the data regarding each relationship of each major concept to hope(p> 0.05), heterogeneous data were eliminated in repeating Q-test. Result: The major variable regarding relationship to self/transcendental being/life(spiritual wellbeing & self esteem) and social support(social support & family support) have very large positive effects on hope(D=l.72, D=l.27). The negative effect of the variable regarding captive state(uncertainty in illness, perceived unhealthiness status, & fatigue) and positive effect of coping(approach coping) on hope are in the level between moderate to large(D=-0.61, D=0.78). All the effects of the major concepts on hope were verified as significant statistically(p=.000). The Fail -Safe numbers showed the significant effects of the three major concepts except coping on hope were reliable. Conclusion: The results can be a guide to advance hope theory for nursing.

  • This paper aims to apply two ways of student evaluation, i.e. peer- and self-evaluation to TBL(team based learning) class and to explore the difference between two evaluations by gender and grade as well as their relationships, and finally to provide an explanation for the improvement of evaluation ways in TBL class. There has been much research about TBL and its related factors. However, according to the examination of both domestic and overseas researches concerning the application of peer- and self-evaluation to TBL class, few studies have focused on them in terms of the engineering curriculum. This study was conducted with 251 engineering students at P University, and peer- and self-evaluation in TBL class have been measured. Our findings show that firstly, there were significant grade differences in self-evaluation of engineering students. Second, there were no significant gender and grade differences in peer-evaluation. Third, we found a significant correlation between the two factors, self- and peer-evaluation. Also there was a significant correlation among variables of subcategories. Based on these findings, it is expected to provide an explanation for the application of peer- and self-evaluation in TBL class and will be useful for the improvement plans of the related courses in engineering school.

  • The purposes of this study were to determine the functions of actions of the limbs during each of the three support phases of the triple jump and their relationships with the performance of the triple jump. Four elite male triple jumpers were participated as subjects. The Pearson product moment correlation coefficient were used to determine and compare the relationships between the change in each component of the normalized angular momentum of the whole body about center of gravity and the actions of the extremities during different support phases. A level of significance at $\alpha$=.05 was set. After analyzing the angular momentum and correlation during support phase of the hop, step, and jump, the following findings are obtained: The actions of the arms created a side-somersaulting angular momentum about the whole body center of gravity toward the side of the free leg during the support phase of the step, and a somersaulting angular momentum about the whole body center of gravity during each support phase. The action of the free leg created a somersaulting angular momentum about the whole body center of gravity during the support phases of the hop and step.

  • The purpose of this study was to identify the relationships of optimistic bias about gastric cancer, self-efficacy of healthy dietary behavior and unhealthy dietary habit in Korean adult men. The subjects were 394 men aged from 20 to 64 who lived in Seoul, Kyonggi Do, Kwang-Ju, Jeonnam Do. Data was collected by questionnaire surveys using convenient sampling. The instruments used for this study were extracted and modified from Lee's(2003). The collected data was analyzed using descriptive statistics, Pearson correlation coefficient, and stepwise multiple regression with SPSS/PC 10.0 version. Unhealthy dietary habit in adult men indicated a significantly negative correlation to optimistic bias about gastric cancer(r=-.159, p=.002) and self-efficacy of healthy dietary behavior(r=-.470, P=.000). The most significant predictors influencing unhealthy dietary habit in adult men were age and self-efficacy of healthy dietary behavior. The variance explained was about 24%. These results suggested that men of young age and lack of self-efficacy of healthy dietary behavior are likely to have unhealthy dietary behavior. Therefore, considering age and facilitating self-efficacy are needed in nursing education and intervention for dietary habit change.

  • Mulberries have importance in the sericulture industry as food for Bombyx mori, silkworm reared for its silk. Korean Morus alba have many cultivars and, for the protection of these cultivars and for utilization in plant-breeding programs, genetic information and the diversity among cultivars are essential. This study with 14 mulberry genotypes was undertaken using RAPD and ISSR fingerprinting to discover the genetic divergences between cultivars. Polymorphism rate among the cultivars produced by RAPD primer was found to be 64.48% and 66.29% relative to ISSR primer. The genetic relationships among the cultivars were identified using a dendrogram constructed with the UPGMA clustering method. Nei's method was used to calculate the genetic dissimilarity coefficients between each pair of genotypes, and the highest dissimilarity coefficient of 0.246 was exhibited between Suwon and Hwanggum cultivars. To determine the efficiency of each primer, a polymorphic index was calculated, and the robustness of the dendrogram was checked using cophenetic correlation coefficient. The results of this study can be utilized for the improvement of mulberry varieties in plant-breeding programs.
