  • This study was conducted to provide information of affective area in developing a nursing curriculum. The sample consisted of 38 sophomores and 43 seniors in Department of Nursing, College of Medicine, Han Yang University. Data were collected by using a structured questionnaire, which consisted of social, home and self control aspects in self concept. The results are summarized as follows; 1. CD In sophomore, as father's academic career were higher, the self concept In social aspects became higher. The students whose father's job was profesion and a white-collar job and who applied for nursing by force and were satisfied with their educational expenses had more positive self concept in social aspects. In senior, as their age were higher, the self concept in social aspects became higher. The students who had religion, recognized the visions of nursing, and were satisfied with their major, had more positive self concept in social aspects. In self concept in social aspects, home environment explained the major variable in sophomore. On the other side, the variable related to major was important in senior. (2) In sophomore, the students who were satisfied with educational expenses and their major had more positive self concept in home aspects. In senior, the students who counseled of their problems with their parents and recognized the visions of nursing had more positive self concept in home aspects. Counsel of their personal problem with their parents explained the most affective variable $(9.6\%)$ for self concept in home aspects in senior. But, it explained only $1.1\%$ of the variance for self concept in home aspects in sophomore. (3) In senior, the students who were unsatisfied with their educational expenses had more negative self concept in self control aspects. 2. There was no significant difference accord ing to the academic year m social, home and self control aspects. 3. The aspects with the highest positive perception of the self concept was home aspects. Self concept in social aspects was more positive perception than in self control aspects. Self concept in self control aspects was lower than in other aspects. 4. Significant relationship a revealed between social aspects and home aspects in sophomore. In senior, the positive correlation were found between social aspects and home aspects and between social aspects and self control aspects. In conclusion, the self concept m home aspects was more positive perception than in other aspects. It resulted from the fact that the nursing uniqueness was based on the spirit of humanity and service. But, when we consider social and self control aspects, good relationship between subjects and nurse is important in nursing, so it is desirable that nursing curriculum include human relationship program. Therefore. in order to strengthen positive self concept, professors and parents must pay attention to student's problems and counsel with then is required.

  • The purpose of this study is to define the difference in the self-concepts between the public and the private primary school students. The data were collected from March 16 to 20 in 1994. The objects of this study are the 5th graded primary school students, total 193, from the public (94 students) and private (99 students) schools located in Chong Ju city. The tool used for this study is SDQ (Self Description Questionnaire). The SDQ is a multidimensional instrument designed to measure seven aspects self-concept hypothesized in Shavelson's hierarchical model. The collected data were analyzed using descriptive statistics, chi-square test, t-test and 2-way ANOVA. The results of the study are as follows: 1. Between the public students and the private students there were no significant differences in the self-concept. 2. 2-way ANOVA using sex (male vs. female) and type of school (public vs. private) were performed. The boys had substantially higher self-concepts in physical ability and the nonacademic self concept. The girls tended to have higher self-concepts for the academic factors (except for Mathematies). 3. 2-way ANOVA using social stratification (upper vs. lower) and type of school (public vs. private) were performed. The upper classes tended to have higher self-concept for the academic factors. The social stratification and sample interactions were statistically no significant.

  • Purpose: This study was done to identify change in self-concept of smoking experience in middle school students. Method: The study was a longitudinal survey design and used only the responses on self-concept and smoking state from the data of the Korea Youth Panel Survey (KYPS). The sample for this study consisted of 3,449 middle school students and the data were collected over a two-year period (2003-2004). Results: Self-esteem scores for the first and second year were significantly higher and self-stigma and aggression scores were significantly lower in the non-smoking maintenance group. There was a significant increase in self-esteem scores for students in second year who quit smoking compared to those in first year. There was a significant decrease in scores for attachment to surrounding people and emotional sense of control in second year students compared to those first year for students in the non-smoking maintenance group and the group that quit smoking. Self-intimacy scores were significantly lower in the smoking maintenance group. There was a significant increase in sex-role identity scores in second year students compared to those in first year for students in the group who newly started smoking. Conclusion: Findings from this study can contribute to designing appropriate smoking prevention strategies to improve self-constructs related smoking experiences in adolescents.

  • Herein we present a diagnostic paper chip that can quantitatively detect albumin without external electronic reader and dispensing apparatus. We fabricated a diagnostic paper chip device by printing wax barrier on the paper and wicking it with citrate buffer and tetrabromophenol blue to detect albumin in sample solution. The paper chip is so simple that we dropped a sample solution at sample pad and measure the ratio of two travel distances of the sample solvent and albumin under the name of retention factor. Our result confirmed that the retention factor was constant in the samples with same concentration of albumin and useful determinant for the measurement of albumin concentration. The paper chip is affordable and equipment-free, and close to ideal point-of-care test in accordance with the assured criteria, outlined by the World Health Organization. We assume that this diagnostic paper chip will expand the concept of colorimetric determination and provide a inexpensive diagnostic method to aging society and developing country.

  • The purpose of this study is to develop a knitwear design with the potential for practical use through a combination of science and design by examining the concept and formative characteristics of fractal geometry and applying them to the development of 3D virtual clothing knitwear design. This study produced five main conclusions. First, the sub-concepts of "Repeatability," "Scale variability," and "complexity," which are based on self-similarity, appear together with simple regularity in the fractal formative characteristics shown in fashion design. Second, fashion fields apply fractal geometry in three-dimensional surface textures and optical textile patterns as a method of expression. Third, it was confirmed that various expressions can be created with fractal patterns by using the SDS-ONE APEX 3-4 design system; moreover, fractal patterns are a suitable design source for the development of Jacquard knitwear patterns. Fourth, in the development of knitted jacquard fractal patterns, by arranging the patterns in perspective, the effect of emphasizing or reducing the human body by optical illusion was shown. Fifth, a knit Jacquard structure with a pattern that exhibits fractal modeling characteristics and applying it to a 3D virtual clothing sample design reduces the time required for sample production while expanding the knit design's expression area and reducing costs. Thus, the clothing sample confirmed the effectiveness of practical knitwear design development.

  • Taking samples of data and using samples to make inferences about unknown populations are at the core of statistical investigations. So, an understanding of the nature of sample as statistical thinking is involved in the area of statistical literacy, since the process of a statistical investigation can turn out to be totally useless if we don't appreciate the part sampling plays. However, the conception of sampling is a scheme of interrelated ideas entailing many statistical notions such as repeatability, representativeness, randomness, variability, and distribution. This complexity makes many people, teachers as well as students, reason about statistical inference relying on their incorrect intuitions without understanding sample comprehensively. Some research investigated how the concept of a sample is understood by not only students but also teachers or preservice teachers, but we want to identify preservice secondary mathematics teachers' understanding of sample as the statistical literacy by a qualitative analysis. We designed four items which asked preservice teachers to write their understanding for sampling tasks including representativeness and variability. Then, we categorized the similar responses and compared these categories with Watson's statistical literacy hierarchy. As a result, many preservice teachers turned out to be lie in the low level of statistical literacy as they ignore contexts and critical thinking, expecially about sampling variability rather than sample representativeness. Moreover, the experience of taking statistics courses in university did not seem to make a contribution to development of their statistical literacy. These findings should be considered when design preservice teacher education program to promote statistics education.

  • 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.
