In this study, FAISC (Family Activity for Improving Scientific Creativity) program was developed and applied to 12 families. FAISC consists of 12 tasks and 12 evaluation papers. Family participants conducted the task individually and evaluated their performance results through discussion and agreement. From the participants' responses, it was found that FAISC tasks were fun but weakly difficult. Participants responded that Guide 1 (Creative thinking methods) and Guide 2 (Related knowledge) were helpful in their performance, and their scientific creativity was enhanced. From the analysis of interview and video recording of participants' behaviors, various positive aspects were observed. Especially on cognitive aspects, harmonious and pleasant family activities were observed. Negative aspects observed in interview and video gave us a practical guide for more effective performance in further application. Finally, according to comparison of evaluation results by family and professionals, the correlation between them was .901. Therefore, we conclude that evaluation of creative activity by family is highly confidential.

Using self-regulation learning strategies that can cultivate the creative and critical thinking required in the era of the Fourth Industrial Revolution, it was applied to the exploration experimental class of the section 'quantitative relationship in chemical reactions' in high school chemistry and the effects on academic performance and scientific attitudes were analyzed. In case of academic achievement, although there was no meaningful difference between the two groups in the pre-test, the average value of the experimental group was significantly higher in the post-test. In the case of scientific attitudes, the difference in average points between the two groups was the greatest in readiness and curiosity. In the post-test of the experimental group, academic achievement showed the highest correlation with meta-cognition and scientific attitude with behavioral regulation, respectively. Considering the effectiveness of metacognition and scientific attitudes, self-regulation learning strategies are the most suitable teaching-learning forms for creativity and personality education in this era.

Previous artificial latent fingerprint solution has shown unsatisfactory results. Therefore, in this study, we developed an artificial latent fingerprint solution close to the actual fingerprint composition by improving the lipid composition. We mixed lipid solution with amino acid solution at v/v ratios as follows: 2:3, 1:4, 1:5, 1:8, 1:10, 1:20. We then dropped the same amount of each proportion of artificial latent fingerprint solution on porous paper and non-porous slide glass. Subsequently, each sample was treated with Oil red O, Cyanoacrylate fuming and Basic yellow 40 staining. As the concentration of lipids decreased, the output also decreased. Both types of surfaces and all concentrations were visually confirmed very well. In addition, the reactivity to lipids was significantly higher compared to the previous artificial latent fingerprint solution. Furthermore, for the quantitative evaluation, it is necessary to conduct additional research on the printing of the artificial latent fingerprint solution.

한 개인의 입장에서도 영재성의 발휘는 매우 중요한 일이지만, 민주국가와 인류공영에 크게 이바지하는 입장에서도 영재성의 발휘는 매우 중요한 일이다. 하지만 현재 운영되고 있는 영재교육을 살펴보면 국가에서 영재교육을 해야 한다고 영재교육의 중요성만 이야기했지 실제로 현장에서 활용할 수 있는 교육과정이나 교육내용을 정해주지 않았기 때문에 실제로 영재교육이 이루어지고 있는 것을 보면 그 내용과 방법은 영재교육을 맡은 기관에 따라 매우 다르게 이루어지고 있다. 현재 17개 대학 부설 과학영재교육원에서 영재교육을 담당하고 있다. 하지만 각 대학 부설 과학영재교육원의 교육과정을 보면 대부분 프로그래밍 위주의 교육을 하고 있고, 그 교육과정도 다른 곳에 개방되어 있지 않아서 각 대학 부설 과학영재교육원마다 교육과정 개발에 상당한 어려움을 겪고 있다. 따라서 본 논문에서는 초등학교에서 고등학교 1학년까지의 10학년에 걸쳐 실시되고 있는 정보통신기술교육내용과 방과 후 특기적성 교육에서 이루어지고 있는 컴퓨터 교육내용, 각 대학 부설 과학영재교육원에서 이루어지고 있는 교육내용을 분석하여 실제로 대학 부설 과학영재교육원에서 활용할 수 있는 초등 정보과학영재를 위한 교육 과정을 개발하였다. 단, 현재 과학영재교육원에서 이루어지고 있는 영재교육이 기초반과 심화반으로 나누어서 운영되고 있는 점을 고려하여, 본 논문에서는 기초반과 심화반 중 기초반에 초점을 두고 연구를 진행하였다.

The primary purpose of the study was to determine the appropriateness o the inquiry processes and its activities as described in Science 8's which were written according to the 7th National Science Curriculum. It was found that the basic processes were well reflected on the textbooks analyzed for the research. However, only a few integrated processes and the inquiry activities could be read on the same textbooks. Furthermore, a large majority of the inquiry processes and activities were not agreed with what the tasks and titles say. Especially, the none of as many as 216 experiments were not coincided with their titles' intentions. Also suggested in the paper were the implications of the results for inquiry-based science education in the Korean middle schools.

Although feather-sexing using sex-linked genes related to feather development is a widely used chick sexing method in the poultry industry, the feather-sexing method has yet to be used for Korean native chickens (KNCs). The purpose of this study was to construct a KNC feather-sexing line using early-feathering (EF) and late-feathering (LF) genes for industrial application. Using 557 reddish-brown KNCs as the basal flock, frequencies of the EF (k) and LF (K) genes were estimated to be 0.814 and 0.186, respectively. This indicating that it would be feasible to construct a feather-sexing line using this chicken group, and we accordingly constructed EF paternal and LF maternal lines. On the basis of test-cross for the selection of LF homozygous (KK) males in the maternal line, we confirmed that three of 40 chickens were homozygous males. The survival rate, body weight, days at first egg-laying, hen-day egg production, and egg weight were analyzed to compare the production performance of EF and LF chickens. The results revealed that EF chickens were characterized by a superior survival rate, whereas LF chickens were superior in terms of egg production rate. However, no differences between LF and EF chickens were detected with respect to other production performance parameters. In addition, assessment of the fitness of sexed chicks produced in the established KNC feather-sexing lines revealed that the accuracy of sexing was 98.6%. Collectively, these findings indicate the feasibility of constructing effective KNC feather-sexing lines with potential industrial application.

Here, we reported 159 varieties of major cultivars using grapevine genetic resources to identify the resistant grape ripe rot cultivars. To do this, we performed pathogenicity assays from these grape cultivars by inoculating Colletotrichum acutatum and Colletotrichum gloeosporioides. Genotyping-by-sequencing(GBS) method was also used to compare genetic diversity among grape varieties. As a result, leaves inoculated with C. acutatum showed that 58 cultivars were susceptible, while 17 cultivars were resistant. In the case of C. gloeosporioides, 34 cultivars were found to be susceptible, while 25 cultivars were resistant. The 8 cultivars that showed resistance to both species were 'Agawan', 'Huangguan', 'Xiangfei', and 5 other cultivars from the hybrids of European and American species. Most of the varieties such as 'Emerald Seedless', 'Tano Red', and 'Rem 46-77(Aestivalis GVIT 0970)' originated in European species were identified as susceptible. These results can be used in the effective management of grape disease. In addition, these findings provide information for the development and cultivation of resistant to grape ripe rot disease cultivars.

The purpose of this study is to analyze the efficiency of budget utilization of science and technology by the Chinese autonomous province and to present the direction of improvement. Data were obtained from the 2013-2017 statistical yearbook of higher education published by the Ministry of Education of China, and efficiency was analyzed using the malmquist analysis method. The analysis found that the low technological progress caused changes in the productivity MPI index, and that cities affected by technological efficiency needed to improve internal factors such as internal coordination and restructuring of universities in the region to increase efficiency. And it was found that areas affected by technological change needed proper response to external factors such as government policy, economic environment, social environment or technological development. This study is meaningful in that it presented reference data in enhancing efficiency of budget utilization of science and technology by autonomy of China, and it is necessary to establish strategies and study essential factors to increase efficiency of inefficient areas in the future.
