The survey method was used in this descriptive study. The purpose in this study was to investigate middle school home economics(HE) teachers' stages of concern, levels of use, and perception about career education, based on the Concerns Based Adoption Model(CBAM). Questionnaire was administrated to middle school HE teachers over the whole country except Jeju Island through mail or e-mail by systematic random sampling. 118 data collected from the responses were finally analyzed statistically with mean, standard deviation, frequencies, percentage, and independent-sample t-test by using SPSS/WIN 12.0 program. The results of the study were as follows: First, most-HE teachers were in stages of the personal concern (86.56) and the informational concern(85.42) about HE career education. Second, the highest number of teachers was in level of refinement(33.1%) use. Third, teachers recognized important goal of HE career education as 'understanding of diverse careers and formating of positive values and attitude about work'. Also they had generally conducted HE career education through 'Understanding Teenager' chapter of a first-year middle school. However they had struggled with difficulty such as lack of data, time, and expertise in conducting HE career education. Therefore, it is necessary that support such as development, supplies, and training opportunities of career education should be provided.

This study was designed to compare the effectiveness and applicability of the HApS$^{TM}$ (Hazard Analysis process System; HUKO, Seoul, Korea) based on Petrifilm$^{TM}$ (3M, St. Paul, MN, USA) with the AOAC (the Association of Official Analytical Chemists) standard total aerobic count (TAC) method and coliform count (CC) method for meat products. The comparisons were carried out using 230 meat samples collected from various retailers: 80 pork samples, 80 chicken samples, and 70 beef samples. In the comparison of the correlation coefficient (r) between conventional method and HApS$^{TM}$ method by a linear regression analysis, the correlation coefficients in total microorganism were 0.97767, 0.90712, and 0.95594 in pork, beef, and chicken samples, respectively. The correlation coefficients in coliform count were 0.82062, 0.94833, and 0.96839 in pork, beef and chicken samples, respectively. All the independent t-test on measurement values between conventional method and HApS$^{TM}$ method represented no significant differences in the means between two methods at the 0.05 of significance level($\alpha$=0.05). Based on the high correlation between HApS$^{TM}$ and the AOAC standard methods in the TAC and CC, it might be compatible to employ the HApS$^{TM}$ method to measure the microbial contamination in livestock products. HApS$^{TM}$ method was simpler and less time-consuming in sample preparation and procedures faster than the conventional method. These results suggested that the HApS$^{TM}$ method could be substitute for the conventional methods in the analysis of microbial contamination measurement in meat products.n meat products.

The purpose of this study is to explore the science learning motivation of technical high school students through comparison with general high school students. 596 high school students and 1063 general high school students participated in the study. Three statistical methods were used for data analysis: two-way ANOVA, independent sample t-test, and Pearson correlation analysis. The results showed that the interaction between school type and grade had a significant effect on the difference of students' motivation for science learning. There was a significant difference in learning motivation among general high school students according to academic year, while there was no significant difference between first and second grader of technical high school students. Especially, technical high school students showed low level of science learning motivation compared to the students in general high school. The correlations among five motivational factors of science learning motivation were also significantly lower than that of general high school students. Lastly, the result of correlation analysis between science motivation and academic achievement showed that second year students in technical high school had less correlation coefficients than the first year students. Given these results, it is necessary to develop a educational strategy for enhancing science learning motivation of technical school students. We will discuss the direction of science education for technical high school based on our findings.

The collected data was analyzed using SPSS 23.0 using descriptive statistical analysis, the independent sample T-test, ANOVA analysis, Pearson correlation, and structural equation analysis. First, significant differences were revealed in the level of attachment avoidance, satisfaction with the marriage relationship, and job motivation according to the age group, in the level of attachment avoidance and satisfaction with the marriage relationship according to the education level, in the level of attachment avoidance and satisfaction with the marriage relationship according to the marriage period, in job motivation according to the position, in satisfaction with the marriage relationship according to the average household income, and in satisfaction with the marriage relationship according to the work shift pattern. Second, although a significant negative correlation appeared between attachment anxiety and attachment avoidance, a significant positive correlation was found between attachment avoidance and job motivation. Also, although a significant negative correlation appeared between attachment avoidance and marital relationship, a significant positive correlation was found between job motivation and marital relationship. Third, to examine the mediating effect of satisfaction with the marital relationship on the relationship between adult attachment and job motivation, a structural equation analysis was carried out. As a result, the indirect effect of attachment anxiety on job motivation turned out to be significant and its complete mediating effect was confirmed. This suggests that when developing programs to improve job motivation within the workplace or consultative interventions for the enhancement of marital relationships, the above characteristics of individuals should be taken into consideration.

If game images use colors improper for certain ages, the characteristics of games disappear, and the efficiency of image expression drops. thus a study in color is very important. Nevertheless, there is a lack of research on this subject. In this study, we investigated the difference of color of game images according to users. User group is divided into all users and users over 18 years old. Among the rank of games,10 each from games for all ages and games for non-teen-rated are selected, and the game-playing images are taken as snapshots to have 100 each images each, A total of 2000 images were extracted and the mean values of RGB and HSB of each game were obtained and independent sample t test was performed. The results showed that the RGB color values between the two users were significantly significant. In the future, it is expected that it will be helpful in color selection when developing psychotherapy games and emotional games using color psychology. Furthermore, we will use color image scales to express colors as adjectives, analyze colors in a variety of ways, and investigate the difference in color of game images in each country.
