The purpose of this study was to compare sex role typing in relation to self-concept in 6th graders by to their residential area. The subjects were 6th grade children: 126 boys and 127 girls. The sample included 85 (42 boys, 43 girls) from a farming area, 111 (62 boys, 49 girls) from Pohang City, and 57 (22 boys, 35 girls) from a fishing area. The instruments used in this study were Shimer's self-concept measure (Suh, 1980) and Bern Sex Role Inventory (Byun, 1979). Statistical analysis of obtained data was by $X^2$ test; 2 (sex) x 3 (residential area) x 4 (sex role category) ANOVA; and $Scheff\acute{e}$ test. The results were as follows: Girls from the fishing area were more masculine than girls from other areas. Androgynous children and urban children demonstrated a higher self-concept. There was no difference in level of self-concept between urban boys and girls, but boys in both farming and fishing areas demonstrated a higher level than girls. In all 3 areas, androgynous children evaluated themselves positively whereas undifferentiated children evaluated themselves negatively. There were significant differences in self-concept according to sex, living area, and sex role category. In the city, the feminine category was related to a negative self-concept while the masculine category was related to a negative self-concept in the fishing area. But in the farming area, feminine boys demonstrated a higher self-concept whereas feminine girls demonstrated a lower self-concept.

The purpose of this study is to investigate significant differences of structural knowledges among the groups(high, middle, low) when the 6th grade subjects structured the concepts of the plane figures, triangle and quadrangle, by concept maps, and to analyse the features of concept maps according to hierarchy. For this purpose, the following two research contents were investigated： 1. Investigating significant differences of structural knowledge in the concepts of the plane figures using concept maps among the groups(high, middle, low). 2. Analysing the features of concept maps according to hierarchy. The structural knowledges represented on the concept maps of triangle and quadrangle which were drawn by the subjects were analysed by propositions, hierarchies, and cross-links. Subject-self Reports about how to make the concept maps were used to analyse the features of concept maps according to hierarchy. The conclusions drawn from the results were as fellows： First, there were significant differences among the groups in proposition links. Second, there wasn't my significant difference among the groups in hierarchy. Third, there were significant differences among the groups in cross-links, and Fourth, the results of analysing the concept maps by hierarchy showed that there were differences among the individuals in constructing the knowledges.

For an accurate analysis of three dimensional linear magnetostatic problems, a new boundary integral equation formulation is presented. This formulation adopts difference magnetic field concept and uses single layer magnetic surface charge as unknown. The proposed method is capable of eliminating numerical cancellation errors inside ferromagnetic materials. In additions, computing time and storage memory are reduced by 75% in comparison with the reduced and total scalar potential formulation. Two examples are given to show its efficiency and accuracy.

Support has always been considered an important nursing concept. However, there is no agreement among nurse researchers as to a conceptual definition of supportive nursing or meaningful supportive behaviors. Clarification of the concept, support in nursing, is necessary to promote communication among nurses on nursing behaviors that are effective in providing support and on understanding the relevant properties and charcteristics of the concept, supportive nursing care. The objectives of the study were : 1. to analyse the concept, support in nursing, in order to provide a definition of supportive nursing care, and 2. to operationalize the definition of supportive nursing care and use it as an experimental nursing intervention for patients with low back pain. The first part of the study used the concept analysis approach developed by Walker and Avant(1983) to define the concept of supportive nursing care. The properties of supportive nursing care, defined by this analysis, included perception of supportive need, reciprocal interaction(Transaction), listening, providing empathy and information related to health, and confirmation of the patient's verbal and non - verbal response. The second part, the experimental part of the study, was done using King's(1970) Interpersonal Theory for Nursing. The concept, supportive nursing care, as defined in the concept analysis was operationalized and used as the experimental intervention. The experiment tested the effectiveness of the independent variable, supportive nursing care on the dependent variables, depression, mood and patient satisfaction, in the patients with low back pain in army hospitals. The instruments used to measure the dependent variables were Zung's(1965) Self- Rating Depression Scale, Ryman and Colleagues'(1974) Mood Questionnaire and LaMonica and Colleagues'(1986) Patient Satisfaction Scale. The experimental design used for this study was a Solomon 4 group experimental design. This design has the strength of allowing for observation of the main effects of supportive nursing care and pretesting, and for observation of the interaction effects of pretesting and supportive nursing care. The design includes one experimental group and three control groups. The Subjects of this study were 150 young male patients with low back pain on Neuro - Surgical Wards in three general army hospitals. There were 35 in the experimental group, 39 in the pre - posttest control group, 36 in the treatment - posttest control group and 40 in the posttest only control group. Supportive nursing care, as operationalized by the researcher according to the concept analysis, was given to the patients in the experimental group and the treatment -posttest control group, individually for 30 minute sessions, every other day for 5 days. Data collection was done using a questionnaire. The data were collected in a pretest one week before the supportive nursing care sessions, a posttest immediately after the sessions and follow- up test one week later. Hypotheses testing was done using 2×2 factorial analysis of variance and Meta analysis(Stouffer's Z method). The results of this study are summarized as follows : 1. Hypothesis Ⅰ, “There will be a difference on depression level between the patients with low back pain who receive supportive nursing care and those who do not receive supportive nursing care”, was supported (F＝8.49, p＜.05). 2. Hypothesis Ⅱ, “There will be a difference on mood level between the patients with low back pain who receive supportive nursing care and those who to not receive supportive nursing care”, was supported (Z meta＝2.17, p＜.05). 3. Hypothesis Ⅲ, “There will be a difference on satisfaction level between the patients with low back pain who receive supportive nursing care and those who do not receive supportive nursing care”, was supported (F＝13.67, p＜.05). 4. ANOVA, done to examine the interaction effect of history and maturation, showed no significant difference on the dependent variables between the observations of the pretest scores of the experimental group, the pretest scores of the pre- posttest control group and the posttest score of the posttest only control group. 5. To test for continuing effect of supportive nursing care, paired t-test was done to compare the scores for the dependent variables at the posttest and at the one week later follow-up test. No significant difference on the scores for the dependent variables was found between the posttest scores and the follow-up test scores for the two groups that received supportive nursing care, the experimental group and the treatment-posttest control group. In conclusion, it was found that in the case of young soldiers with low back pain in army hospitals, their depression level was decreased, their mood state was changed positively and their satisfaction level was increased by receiving supportive nursing care. Further, the effectiveness of the supportive nursing care lasted for at least one week in this study. The significance of this study to nursing is in the analysis of the concept of supportive nursing care and the demonstration of the effectiveness of supportive nursing care as an intervention within the limits of the study.

Background: The objective of this study was to examine the effect of self-concept levels and perceived academic achievements of sixth, seventh and eighth grade primary school students upon their perceptions about smoking. Method: The data were collected with the Socio-Demographic Data Collection Form, Pier-Herris Self-Concept scale and Children's Decision Balance Scale. The study sample consisted of 374 students receiving education in the sixth, seventh and eighth grades of three primary schools, which were selected among primary schools of Izmir Provincial Directorate for National Education representing three socio-economic groups with a simple random sampling method. The data were collected in December 2012-January 2013. Percentages and the t test were used in the evaluation of the data. Results: While students with a positive self-concept had score averages of $7.12{\pm}2.18$ regarding the lower dimension of smoking pros and $29.0{\pm}2.47$ regarding the lower dimension of smoking cons, their counterparts with a negative self-concept had score averages of $8.61{\pm}3.76$ (p=0.000) and $28.1{\pm}3.49$ (p=0.004), respectively. According to self-perception, there was statistical difference between perceptions of students regarding smoking (p<0.01). While students perceiving themselves successful had score averages of $7.81{\pm}3.13$ and $28.5{\pm}3.19$ regarding the lower dimension of smoking benefit and harm, students perceiving themselves unsuccessful had score averages of $8.27{\pm}3.39$ (p=0.333) and $29.01{\pm}2.05$ (p=0.235), with no difference determined. Conclusion: Students with a positive self-perception had a low perception of smoking pros and a high perception of smoking cons. Perception of academic achievement did not affect the pros and cons perceptions of children regarding smoking.

Purpose : This study aimed to verify the effectiveness of the clinical ladder system (CLS) by identifying the perception of the CLS, professional self-concept, self-efficacy, and organizational commitment among intensive care unit (ICU) nurses. Methods : Data were collected through a questionnaire survey of 173 nurses working in 11 ICUs at a tertiary hospital in Seoul. Results : The perception of the CLS, self-efficacy, and organizational commitment showed significant difference according to the CLS level. As a result of the partial Spearman correlation analysis after adjusting for demographic difference according to CLS (age, marital status, education, and clinical career), CLS positively correlated with the perception of the CLS (r=.16, p=.045), professional self-concept (r=.24, p=.001), and self-efficacy (r=.21, p=.007). On the contrary, organizational commitment negatively correlated with the perception of the CLS (r=-.43, p<.001) and self-efficacy (r=-.32, p<.001). Conclusion : The CLS is effective for professional self-concept and self-efficacy. However, specialists 2 nurses, who had high professional self-concept and self-efficacy, showed low level of organizational commitment. Thus, it is necessary to examine the factors of work burden and career plateau that are imposed after promotion and improve experience and planning according to the growth needs. Moreover, regular evaluation of the CLS will require hospital support to ensure that ICU nurses appreciate and actively participate in the support.

The purpose of this study is to investigate the conceptions about altitude of the Sun of elementary students according to differences by the spatial ability. In this study through the qualitative analysis, 4 students who were similar understanding levels of concepts to altitude of the Sun and differences by the spatial ability were selected out of 75 in 6th grade elementary located in Sunchang, Jellabuk-do Province. 4 students for the qualitative analysis were selected by the test instrument of spatial ability and altitude of the Sun. The results of study was students with higher spatial ability were higher understanding levels of concepts to altitude of the Sun. However, both of student with higher and lower spatial ability showed a false concept to the expanded concepts into outer space like a cause of seasonal change, change of altitude of the Sun by latitude unlike the intution. Students with lower spatial ability didn't form the scientific concepts, not only a cause of seasonal change and change of altitude of the Sun but also difference of energy density by altitude of the Sun. A student of two with lower spatial ability has been impediment strongly to form the scientific concept by the false concepts to the distance. The findings were as follows; Learning to altitude of the Sun regardless of the difference of spatial ability should be learned to interact to the intution, celestial movement and model experiment. To students with lower spatial ability should be developed teaching methods to understand the relation between the Sun and celestial movement.
