The purpose of this study is to develop an intervention program for improvement of elementary science-poor students' Basic Science Process Skill (BSPS) and to validate the intervention program's effectiveness using eye-tracker. The participants of this study were 35 elementary science-poor students. This study's method was the analysis of real-time eye movements during basic science process skill problem solving. SMI's 120 Hz iView XTM RED was used to collect EMD (eye movement data). Experiment 3.4 and BeGaze 3.4 programs were used to design experiment and to analyze EMD. The results of this study are as follows. First, we developed an intervention program including BSPS instructional strategy, behavior of teachers & student according instructional strategy stage, teachinglearning plan and learning note. Second, science poor students' BSPS ability has improved statistically significantly through the application of intervention program and BSPS problem-solving time decreased statistically significantly. Third, AFT (average fixation time) of BSPS Question and keyword area decreased statistically significantly. Fourth, APD (average pupil diameter) of BSPS problem-solving process expanded statistically significantly. Fifth, AST (average saccade time) of BSPS problem-solving process increased statistically significantly. Sixth, AFET (average fixation entry time) of BSPS problem-clue area was accelerated statistically significantly, AFT of BSPS problem-clue area reduced statistically significantly.

테크놀로지의 중요성이 증가함에 따라 교사와 예비 교사의 테크놀로지 관련 지식의 중요성이 증가하고 있다. 이에 따라 예비 교사의 TPACK을 향상시키기 위한 다양한 연구가 진행되고 있다. 본 연구에서는 프로그래밍을 접목한 TPACK-P 모델을 기반으로 개발한 교육 프로그램을 예비 교사에게 적용하고, 예비 교사의 TPACK 변화를 관찰하였다. 교육 프로그램의 적용은 K 대학의 2016년 2학기 강의의 일부로 진행하였으며, 연구 대상은 수업을 수강하는 예비 교사 19명이었다. 교육 프로그램을 적용하기 전과 후에 박기철과 강성주(2014)의 검사 도구를 활용하여 예비 교사의 TPACK을 측정하였고, 대응 표본 t-검정을 통하여 예비 교사의 TPACK 변화를 통계적으로 분석하였다. 분석한 결과, TPACK-P 기반 교육 프로그램은 예비 교사의 TPACK 발달에 효과적인 것으로 나타났다. 세부 영역에서는 PCK를 제외한 모든 영역에서 통계적으로 유의미한 차이가 나타났다.

The present research is aimed to observe the effects on the peer counseling program which can increase the communication skills and social efficacy of high school students. In order to do the present research, I have taken 16 high school students, who want to join to this research, within A city. I have separated those students into two groups: an experienced group of 8 students and a controlled group of 8 students. Mann-Whitney U and Wilcoxon Signed Ranks test were adopted to analyze collected data from the peer counseling program. The results of this research indicated that the level of communication skills have been increased after peer counseling intervention program of the experienced group, and the level of occupational stress also have been increased after peer counseling intervention program of the experienced group. This result showed that, the peer counseling program could stimulate the communication skills and social efficacy of experienced group significantly comparing with the result of the controlled group. From the result I have confirmed that, the peer counseling program have positive effects to increase the high school students' communication skills and social efficacy.

This study carries out an empirical analysis of how workplace innovation affects employment growth. The theoretical model and hypotheses of this study are drawn from the previous research on the employment effects of innovation. I use the data on Workplace Innovation Indicators(2013-14) collected by Labor Foundation. As the regression models for this study, I adopt OLS models whose dependent variable is employment growth rate, and whose main independent variables are the adoption and the intensity(standardized values) of three innovative work practices such as TQM, employee suggestion plans and multi-skill training programs. The results of this study indicate that the adoption of workplace innovation does not have significant effects on employment growth, but that the intensity of workplace innovation has weakly positive effects on employment growth. Besides, the results of this demonstrate show that government-subsided organizational innovation consulting and training hours per capita have positive employment effects, but that wage level and prior employment size have negative ones. Finally the empirical results are outlined, and their limitations and the future direction of research on this topic are discussed.

The United States Census Bureau released a new version of X-13ARIMA-SEATS that integrates X-12-ARIMA with TRAMO-SEATS. This paper compares a seasonal adjusted series from X-13ARIMA-SEATS and those from X-12-ARIMA. An X11 filter and SEATS filter were used for the X-13ARIMA-SEATS. The result of the comparison suggests that seasonal adjusted series using X-13ARIMA-SEATS with the X11 filter are similar to those of X-12-ARIMA.

The purpose of this study was to obtain the basic data for the effective development and operation of forest healing by analysing the preference of adults on the forest therapy program. The survey of 516 normal adults on the forest therapy program was conducted. Using SPSS 21.0 Program, data analysis of descriptive statistics and correlation analysis of each program confirmed number of covariate, and so we conducted a factor analysis to short meaningful data. And then we looked at the forest healing program preference difference according to demographic characteristics(sex, age, residence, occupation) through reliability analysis, frequency analysis, T-test, analysis of variance(ANOVA). Facter analysis was performed by use of the VariMax orthogonal rotation factor analysis to abbreviate 37 forest therapy program. Through this, the program has been reduced such as 7 program group(1: psychology-based treatment, 2: teaching and counselling-based treatment, 3: camping and forest bath-based treatment, 4: diet-based treatment, 5: nature and plant-based treatment, 6: meditation-based treatment, 7: respiration and yoga-based treatment) and 7 independent programs(1: sleeping in the forest, 2: vision quest, 3: soaking in water, 4: walking wearing shoes, 5: viewing the forest, 6: mountaineering, 7: athletics in the forest). With this criterion, the forest therapy program difference in accordance with sex, age, residence, occupation has been investigated. First, it was verified that there was a significant difference between male and female in the group of such as psychology-based treatment, diet-based treatment, mountaineering. Second, there appeared a significant difference in groups such as teaching and counselling-based treatment, camping and forest bath-based treatment, nature and plant-based treatment, respiration and yoga-based treatment, athletics in the forest. Third, according to the residence, there appeared a significant difference in groups such as psychology-based treatment, teaching and counselling-based treatment, diet-based treatment, nature and plant-based treatment, meditation-based treatment, vision quest, mountaineering, athletics in the forest. Fourth, according to the occupation, there appeared a significant difference in groups such as nature and plant-based treatment, medication-based treatment, vision quest, walking wearing shoes, viewing the forest, mountaineering. As shown before, it seems to be necessary that we should be mindful of this investigation which shows variety of preference of adults on the forest therapy program according to demographic characteristics. We expect the results of this study to be utilized as basic data for the development of forest therapy program targeting on adults.

The results of the study are as follows. First, in learning capability according to participation in learning programs, we found statistically significant differences in the ability to organize information, resource utilization, self-awareness, self-improvement and sociality. Second, there were no statistically significant differences in the ability to organize information, resource utilization, self-awareness, self-improvement and sociality in participating in learning programs. Third, there were statistically significant differences in the ability to organize information, resource utilization, self-awareness, self-improvement and sociality in not participating in learning programs. Fourth, there were statistically significant differences in the ability to organize information, resource utilization, self-awareness, self-improvement and sociality in experiencing difficulties in learning. Fifth, learning capabilities in specific areas that students wanted to improve had no statistically significant differences in the ability to organize information, resource utilization, self-awareness. However, there were statistically significant differences in self-improvement and sociality.
