The main purpose of this study was to develop a teaching program, especially designed to improve the skills of control variables. The secondary purpose was to investigate the effect of the program on enhancing students' scientific reasoning and understanding. The program was designed based on the 3-step learning model: i.e. students recognize the necessity of controlling the variables (step 1), perform their own experiments (step 2), and reflect on their variables control process (step 3). The program included 9 topics of increasing difficulty. In results, Lawson's SRT scores increased in both experimental and control groups after application of the program, but the difference was not statistically significant. After the application, there was an increase in type A and type B which implied that students' skills of control variables was improved. In addition, responses of students in the experimental group to the open-ended items showed that it was challenging for them to think scientifically and critically when controling variables, but they ended up feeling proud of their achievement after the program.

The purpose of this study was to develop teaching stratege focused on Conservational reasoning, Proportional reasoning, Variable-controlling reasoning, Probabilitic reasoning, Correlational reasoning, Combinational reasoning and investigate its effects on enhancing students' logical thinking skills through the science teaching on common education. And the teaching materials was implemented to 110 students in middle school over about six months. The results indicated that the experimental group presented statistically meaningful improvement in logical thinking skills (p<05). Especially, this teaching stratege was effective on Conservational reasoning, Variable-controlling reasoning, Combinational reasoning but was not effective on Proportional reasoning, Probabilitic reasoning, Correlational reasoning (p<.05). Logical thinking according to the teaching strategy skill was not affected by gender, cognitive level, academic achievement (p<.05).

The purposes of this study were to develop teaching strategy enhancing the activity to explore variables and to examine the instructional influences on students' creative thinking skills and critical thinking skills. In this study, a model using listing-excluding-controlling variables (DPAS model) was designed and applied to the existing 'Teaching model for the enhancement of the creative problem solving skills'. And it was implemented to preservice science teachers for the one semester. Results indicated that the experimental group presented statistically meaningful improvement in creative thinking skills, especially in recognizing problems, making hypothesis, controlling of variables and interpreting & transforming of data (p<.05). In addition, the strategy contributed to improve critical thinking skills, especially in making hypothesis and making conclusion & generalization (p<.05).

The aim of this study was to examine growth trajectories of delinquent behaviors during adolescence. In addition, the effects of protective and risk factors that might account for individual difference in the level of delinquent behaviors and in the rate of change were examined. Four waves of data in the Korea Youth Panel Survey(KYPS) were used to analyze the linear growth modeling. The sample consisted of 3346 adolescents who were assessed at 4 measurement waves with approximately 1-year intervals. The results showed significant individual differences in both final level of delinquent behaviors and in the rate of change across 3 measurement occasions. Adolescent gender, family's socioeconomic background predicted the final level and the rate of change of delinquent behaviors. The protective effects of positive parenting and self-control were significantly associated with problem behaviors and the risk effects of the association with deviant peers and negative stigma were significant on the final level of delinquency. Self-control and deviant peer affiliation had differential influences over time significantly. Practice and policy implications as well as further research topic were discussed in the light of searching for important factors in preventing adolescent problem behaviors.

The purpose of this study was to develop teaching materials using pyramid model of divergent thinking, inverse pyramid model of convergent thinking and evaluate the effects of its applications. The teaching materials was implemented to 110 students (The experimental group is 57, The control group is 53) in middle school for about 8 months (from May to October). Results indicated that the experimental group presented statistically meaningful improvement in creative thinking skills, especially in fluency, flexibility and originality. There was no interaction effect about creative thinking skills between the teaching strategy and cognitive level, achievement, gender of those students. Also the teaching materials contributed to improve critical thinking skills, especially in making hypothesis, control of variables transformation and interpretation of data. There was no interaction effect about critical thinking skills between the teaching strategy and cognitive level, achievement, gender of those students.

Objective : This study is purposed to suggest basic data of developing program preventing Herpes zoster by analysis of related variables for adults over 50 years old. Methods : Data had been collected by 225 adults over 50 years old who participated in health program in B city, interested program of welfare service center in C city and community residence through self-administered questionnaire from $15^{th}$ June to $15^{th}$ July 2016. The collected data was analyzed by IBM SPSS statistics v.18 and AMOS v.18. Results : Based on the verification of model by the results of the study, ${\chi}^2=365.785$(df=193, p<.001), $CMIN/DF({\chi}^2/df)=1.90$, GFI=0.88, AGFI=0.84, NFI=0.88, TLI=0.93, CFI=0.94, RMR=0.07, RMSEA=0.06, The action of Herpes zoster preventive behavior and perceived behavior control for adults over 50 years old made direct influence to the Herpes zoster preventive behavior and the attitude of preventive behavior showed the largest total effect. Conclusions : In conclusion, for improving action of Herpes zoster preventive behavior for adults over 50 years old, it is important to induce change of attitude about Herpes zoster preventive behavior. Also, the development and strategy of education program, which can improve action of Herpes zoster preventive behavior, are necessary through emphasizing perceived behavior control about Herpes zoster preventive behavior.

The purpose of this study is to find out the relationship among the degree to provide emotional labor, personal relationship and the intent to stay of female care service workers. Specifically, this study focuses on the mediating effect of the personal relationship (client and agency relation). The path analysis and structural equation modeling analysis were performed on the collected data using SPSS18.0. and AMOS 8.0. And Sobel test conducted for examine the mediating effect. The results are the followings. First, the result of the analysis showed that agency relationship was an indirect factor as the partial mediating effect on relationship between the degree to provide emotional labor and the intent to stay for the care women workers. The result suggests that education utilizing various techniques and strategies to overcome the difficulty accompanied by emotional labor such as communication education and the government try to effort managing and controlling the agency which impact on the labor condition of care workers. Second, the government also tries to provide the trust and collaboration network system which construct a good relationship between the care worker and the agency.

This study was a descriptive research study conducted to determine how nursing students' good death awareness and nursing attitudes toward dying patients affect their empathy. The subjects of the study were 155 nursing students, and data were collected using an online survey method. Data analysis was performed using descriptive statistics, independent t-test, one-way ANOVA, and multiple regression using the IBM SPSS Statistics 26. Higher attitude toward care of dying (B=.312) had a statistically significant positive effect on empathy capacity (p<.010). The variables that affected nursing students' empathy capacity were end-of-life experiences of relatives (𝛽=.226) and attitude toward care of dying (𝛽=.220). The regression model was statistically significant (F=6.968, p<.001), explained 10.4% of empathy. This study is expected to be used as basic data for the development of programs to strengthen the empathy capacity of nursing students in the future.
