  • The purpose of this study was to investigate visual evaluation according to various methods of motif presentation and the value contrast between the motif and background. The instruments developed for this purpose were two sets of stimuli and a response scale. the first set consisted of pattern stimuli. they were eight photographs of floral patterns constructed by using six different motif presentation methods and two different value contrasts. The second set had eight clothing stimuli, photographs of clothings with the above floral patterns. The 7-point sementic differential scale of 19 bipolar adjectives was used as the response scale. The data was analyzed by factor analysis, ANOVA and T-test. The major findings from this study were as follows; 1. Four factors emerged to account for the dimensional structure of the floral pattern image. These factors were attractiveness, tenderness, attention, and maturity. among them attractiveness and tenderness were the major dimensions 2. The patterns and the clothings had no significant difference from each other in terms of attractiveness and tenderness, but in terms of maturity and attention. The pattern presented a cute and sober image, but the clothing presented mature and gorgeous image. 3. methods of motif presentation had significant effects on all the factors. The pattern by shading method gave the most attractive and soft image, the one by line the most soberest, the one by area the most gorgeous, the one by collage the most unattractive, hardest, and cutest, and the one by mosaics the maturest. 4. The value contrast between the motif and background had no significant effects on attractiveness and maturity, but on tenderness and attention. The patterns with a high valued background presented a soft image, but the one with a low valued background a hard image. The patterns with a low valued area presented gorgeous image.

  • The purpose of this study was to investigate the causal relationship of early adolescents' personal variables and social support on their self-esteem by grade. Information on 226 6th graders from elementary schools and 226 1st year students from middle schools in Busan was collected. Early adolescents' prosocial behavior, academic achievement, social support, and self-esteem were assessed using their self-reports. For the data analysis, Cronbach's ${\alpha}$, t -test, Pearson's correlation coefficient, and multiple regression were used. The collected data were analyzed by the SPSS ver. 21.0 program for Windows. The major findings were as follows: first, early adolescents' prosocial behavior, academic achievement, social support demonstrated a significant difference between grades. Second, peers' social support was the most powerful determinant of self-esteem in both the 6th graders from elementary schools and the 1st year middle school students. Third, prosocial behavior had the greatest total effect on self-esteem in the case of both groups of students. The middle schoolers' academic achievement had no causal effect on their self-esteem. The findings from this study indicate that early adolescents' personal variables and social support are important elements that affect their self-esteem differently depending on their grade. Further, the findings of this study can be used as fundamental data to develop a teaching plan and provide counseling for early adolescents in order to increase their self-esteem.

  • The study was examined the multiple mediated effects of maternal self-efficacy and depression between perception gap about paternal involvement and marital conflict for dual-income parents. The data used were the fifth year data of the Panel Study on Korean Children from Korea Institute of Child Care and Education in 2012. The subjects consisted of 449 dual-income parents with more than one child. Data were analyzed using descriptive statistics, one-way analysis of variance, paired t -test, and correlation. SPSS macro and bootstrapping methods also assessed the mediation effects of maternal self-efficacy and depression between the perception gap about paternal involvement and marital conflict in dual-income parents. The results of this study were as follows. Significant positive correlations were observed for marital conflict, perception gap of dual-income parents about paternal involvement and maternal depression. Perception gaps by parents and self-efficacy were negatively correlated. Perception gaps by parents showed a direct effect on marital conflict. The results of indirect effects of all mediators showed the mediated effect of maternal self-efficacy and depression. The study revealed that the perceptive gap about paternal involvement has a significant impact on maternal self-efficacy and depression, as well as marital conflict. The perceptive gap of dual-income parents about paternal involvement has critical effects on marital conflict as much as the quantity of paternal involvement.

  • Background: Forward head posture (FHP) is common postural malalignment. FHP is described relatively extension to upper cervical and lower cervical is relatively flexion. Although several researchers mentioned the lower cervical flexion posture in FHP, most of the studies related to FHP is focused on the deep cervical flexor function. Objects: The purposes of present study is to compare the cervical strength (upper cervical extension [UCE], lower cervical extension [LCE], upper cervical flexion [UCF], lower cervical flexion [LCF]) between individuals with and without FHP. Methods: Fifty-one participants are recruited. Participants who have the craniovertebral angle (CVA) less than 48 degree were classified to the FHP group (n = 24) and the others were included in without FHP group (n = 27). The cervical strength (UCE, LCE, UCF, LCF) were measured using Smart KEMA strength sensor and the strength data was normalized by body weight. All strength measurement conducted at head and neck neutral position in sitting. Independent t-test was used to compare the cervical strength between individuals with and without FHP. Results: The mean value of CVA was greater in without FHP group than with FHP group (p < 0.000). The strength value of UCF (p < 0.002) and LCE (p < 0.001) was significant less in FHP group than without FHP group. But no significant differences were seen in the LCF and UCE strength between two groups. Conclusion: UCF and LCE weakness in FHP group should be considered to evaluate and manage the individuals with FHP.

  • Exoticism, by definition, is 'the charm of the unfamiliar', usually because of associations with a distant country. In the western-centric world, exoticism implies non-western or oriental style. The purpose of this study was to identify Koreans' perception of "Exoticism", and to compare the perception of exotic fashion image according to gender and education differences. Empirical study was composed of two parts focusing on gender and education effects respectively. For the first part, data were collected by self-administered questionnaires distributed to 280 respondents at 2 universities and 2 high schools during August and September 2005. The sample was consisted of 140 male and 140 female. A measurement, including 24 image adjectives to evaluate 16 fashion stimuli, was developed. Data were analyzed by descriptive statistics, correlations, t-test, and MDS. There was no difference in the perception of exotic fashion image according to gender. Both gender groups perceived exotic image as western image and non-exotic image as oriental image. Thus it could be said that Koreans perceive western-based fashion as foreign and exotic. This finding implies the relativity of "Exoticism." In the second part, the measurement and the analysis methods were the same with the first part. The respondents were consisted of 70 fashion majored female students and 70 non-fashion majored female students. There was considerable difference between fashion and non-fashion major groups in their perception of exotic fashion image. Whereas non-fashion major group perceived exotic image as western image and non-exotic image as oriental image, fashion major group perceived exotic image as both western and oriental image. This result suggested that fashion major group have western-centered conception as well as general perception character of Korean.

  • Purpose: The purpose of this study was to analyze the effects of simulation-based training on nursing students' knowledge and ability to perform advanced cardiovascular life support. Methods: A nonequivalent control group non-synchronized design was used. The participants were, in total, 59 junior college nursing students (experimental group: 30, control group: 29). The data were analyzed with a ${\chi}^2$-test, independent t-tests, and analysis of covariance (ANCOVA) using IBM SPSS Statistics 23 program. Results: The experimental group ($80.8{\pm}8.4$), who received simulation-based advanced cardiovascular life support education, showed a higher level of knowledge of advanced cardiovascular life support than the control group ($75.0{\pm}9.9$), who received lecture-based education. In addition, the experimental group ($106.4{\pm}11.9$) showed a higher level of ability to perform advanced cardiovascular life support than the control group ($86.5{\pm}9.9$). Conclusion: Simulation-based advanced cardiovascular life support education was more effective for increasing the knowledge and performance ability of college students than lecture-based education. Therefore, simulation-based training should be used to improve the knowledge and ability of nursing students and should be applied with reinforced systematic education programs.

  • Purpose : The purpose of this study was to identify the factors influencing the general hospital nurses' confidence about the advance directives (ADs). Methods : This is a descriptive cross-sectional study. A total of 105 nurses were asked questions about characteristics, knowledge, attitude, learning needs, and confidence the about ADs, using structured questionnaires. Data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression. Results : The mean scores of knowledge were 7.26±1.47; attitude, 2.80±0.31; learning needs, 4.22±0.62; and confidence, 2.57±0.74. It was observed that knowledge had significant correlations with attitude (r=.43, p<.001), learning needs (r=.29, p=.003), and confidence (r=.40, p<.001), and attitude had significant correlations with learning needs (r=.31, p=.001) and confidence (r=.45, p<.001). Using multiple regression analysis, it was found that confidence was significantly influenced by knowledge (β=.27, p=.007), attitude (β=.21, p=.043), and experience of nursing or counseling a patient who wrote ADs (β=-.19, p=.046). The explanatory power of this model was 37.9% (F=5.16, p<.001, R2=.379). Conclusions : These findings suggest the need to develop a program to enhance nurses' knowledge, positive attitude, and experience of nursing or counseling a patient who wrote ADs.

  • By analysing the examination papers from third grade high school students, we classified the errors occurred in the problem solving process of high school 'Geometry and Vectors' into several types. There are five main types - (A)Insufficient Content Knowledge, (B)Wrong Method, (C)Logical Invalidity, (D)Unskilled Expression and (E)Interference.. Type A and B lead to an incorrect answer, and type C and D cannot be distinguished by multiple-choice or closed answer questions. Some of these types are classified into subtypes - (B1)Incompletion, (B2)Omitted Condition, (B3)Incorrect Calculation, (C1)Non-reasoning, (C2)Insufficient Reasoning, (C3)Illogical Process, (D1)Arbitrary Symbol, (D2)Using a Character Without Explanation, (D3) Visual Dependence, (D4)Symbol Incorrectly Used, (D5)Ambiguous Expression. Based on the these types of errors, answers of each problem was analysed in detail, and proper ways to correct or prevent these errors were suggested case by case. When problems that were used in the periodical test were given again in descriptive forms, 67% of the students tried to answer, and 14% described flawlessly, despite that the percentage of correct answers were higher than 40% when given in multiple-choice form. 34% of the students who tried to answer have failed to have logical validity. 37% of the students who tried to answer didn't have enough skill to express. In lessons on curves of secondary degree, teachers should be aware of several issues. Students are easily confused between 'focus' and 'vertex', and between 'components of a vector' and 'coordinates of a point'. Students often use an undefined expression when mentioning a parallel translation. When using a character, students have to make sure to define it precisely, to prevent the students from making errors and to make them express in correct ways.

The research instruments used in this study were HPLP II, Visual analogue scale, Self-esteem scale, Family support scale, Self-efficacy scale. In data analysis, SPSS PC ver 10.0 program was utilized and data were analyzed using descriptive statistics and t-test, ANOVA, Multiple Stepwise Regression and Pearson's correlation coefficient. Result: The average score of the pain, self-esteem, family support, self-efficacy, health promoting behavior was 5.38, 3.37, 4.29, 70.30, 2.68, respectively and the variable with the highest degree of it's subscale was interpersonal support(3.08), whereas the one with the lowest degree was exercise(1.66). There was a positive correlation(r=.327, p=.000) between the self-esteem and health promoting behavior. There was a positive correlation(r=.540, p=.000) between the family support and the self-efficacy and health promoting behavior. Family support, self-efficacy and marital status were significant factors to explain a variance of health promoting behavior in patients with chronic arthritis(51.6%). health promoting behavior. There was a positive correlation(r=.477, p= .000) between Conclusion: The health promoting behavior were positively correlated with self-esteem, family support and self-efficacy. These findings help to understand relationships among self-esteem, family support and self-efficacy in chronic arthritis patients. In addition, family support, self-efficacy and marital status were the mainly influencing factors of health promoting behavior. Among these variables family support was the most significant factor to predict a health promoting behavior. According to the results of this study, family support must be considered as a main factor in the nursing strategy for health promoting behavior of chronic arthritis patients.

  • The arthritis patients suffer from psychological, social and spiritual problems as well as physical problems because the arthritis is not curable and has chronic pain, joint deformity, limitation of activity and physical dysfunction for all of his life. Especially if they do not find the meaning in their lives, they will experience spiritual distress seriously. Therefore, it is important that nurses help the patients to find the meaning in their lives and to reduce spiritual distress. The purpose of this study is to provide a basis for nursing intervention strategies to minimize the arthritis patients' spiritual distress and understand the relationship between the meaning of life and the spiritual distress in arthritis patients. The samples were composed of 157 arthritis patients. Data collection was carried out from October 1, 1998 to February 28, 1999. Data were analyzed using a SAS program for descriptive statistic, Pearson correlation, t-test, ANOVA, linear regression. The results were as follow; 1. The scores on the meaning of life scale ranged from 51 to 130 with a mean of 93. 2. The scores on the spiritual distress scale ranged from 26 to 91 with a mean of 60. 3. There were significant correlations between the meaning of life and the spiritual distress(r=.53, p=.00). 4. The linear regression analysis showed that the meaning of life explained 13% of the spiritual distress. 5. In the degree of the meaning of life and the spiritual distress according to the general characteristics, the level of the meaning of life in arthritis patients was different by the duration of incidence(F=2.71, p=.03). In conclusion, the nursing intervention strategies to reduce the spiritual distress in arthritis patients must take into account the meaning of life.
