  • Areas of forensic have been used as a tool in many fields of police investigation, detective, such as research relating to the criminal investigation. Despite it is failure to obtain a central role and status, forensic is nonetheless necessary. This study recognizes the importance of police and forensic activities, and in reviewing the level of support for actual condition of science and forensic investigations, and it has tried to find the problems. Based on this, this study discusses development plans of the working system to explore whether it can improve the efficiencies of forensic activities from the realistic restrictions. These days, one of the main problems that police forensic activities encounter is lack of labor and human resources on the arrested. Therefore, this study aimed to looking for realistic ways to improve efficiencies of forensic agents First, changing the working system and the restructuring the command system requires a long-term perspective. In other words, a regional forensic system is required. Second, the establishment of a Police Investagation Specialization to ensure the professionalism of the investigation is necessary. Third, the system should improve forensic specialties. Fourth, the R&D organization should established to improve the capability for forensic investigations.

  • Constructivism has had a great influence on science education over the last two decades. The purpose of this article is twofold: First, to describe the characteristics of constructivism and, second, to suggest an ideal forms of science education in Korea as implied in constructivism. A review of the literatures in the first area shows that constructivism is philosophical/psychological view which believe in the social nature of the construction of scientific knowledge and its learning. And the analyses of a few schools of constructivism suggest decision-making as a goal of science education, learning as the active construction of meaning through interaction between learner and learning environments, and discussion and cooperation as appropriate teaching strategies. At the same time, the results necessitate teaching ethical aspects of science in the secondary schools, and also imply that performance assessment must be emphasized in evaluation of science education.

  • The hepatocyte nuclear factor 4 alpha ($HNF4{\alpha}$) gene is related to lipid transport, including abdominal fat and growth, in chickens. Interestingly, the A543G SNP within the $HNF4{\alpha}$ gene has previously been reported to be associated with body weight in both broilers and Korean native chickens (KNCs). However, its exact position within the HNF4 is not yet reported. This study aimed to identify the position of the A543G SNP and to identify additional SNPs that can be used as genetic markers in KNCs. A total of 128 KNCs were used for the sequencing and analysis of these genetic associations. As a result, A543G SNP was located in intron 4 of the $HNF4{\alpha}$ gene; it is reported as rs731246957 in the NCBI database. Fourteen SNPs were detected in the sequenced portion of the $HNF4{\alpha}$ gene; three of these, rs731246957, rs736159604 and new SNP, intron 6 (249), were significantly related with growth in the chickens. In this study, the TT genotype of rs731246957, previously reported as A543G SNP, the GG genotype of rs736159604 and GT of new SNP have are highly associated with body weight from birth to 40 weeks of age in KNCs (P<0.01). These results suggest that rs736159604, rs731246957 and intron 6 (249) SNPs within the $HNF4{\alpha}$ gene could function as growth-related markers in the selective breeding of KNCs.

  • Science of gaining knowledge by the study of things[格物致知學]' is the translation of Science in Chosun age. Science of gaining knowledge by the study of things[格物致知學] which is the highest stage of new science is the symbol of the transfer of universal culture to the western modern civilization from old-fashioned confucianism. Modern western culture and the scientific way of thinking make man as a object to scientific research. Thinking method of social Darwinism made man believe to think like them as the modern method. And also such thinking method made man militarism and imperialism are right thinking and research methods. The core to think the science of gaining knowledge by the study of things[格 物致知學] as a violent thinking method is the Confucianism. By this method Park Eun-sik criticize this side of scientific technology as the means of militarism. Till now we pointed to think of the traditional philosophy as the tool of the western modern philosophy about war criminal. Now we rethink of the Confucianism asset as a tool of Korean Modern Culture. Musungmumul[無誠無 物] will offer moral basis to think humanism of the scientific technology of the modern western culture.

  • Antibiotics have greatly contributed to the treatment and prevention of bacterial diseases in humans, animals, and fish. However, antibiotic misuse has led to the emergence and spread of multidrug-resistant bacteria. In addition to antibiotic discovery research, efforts are being made to combat such multidrug-resistant bacteria using antimicrobial agents, antioxidants, host immune enhancement, probiotics, and bacteriophages, as well as various symptomatic therapies. To discover novel bioactive compounds, it is crucial to adopt approaches that incorporate fresh ideas, new targets, innovative techniques, and untapped resources. Halophytes are plants that grow in high-salt soils and are known to adapt to salt-induced stress through unique metabolic processes that produce secondary metabolites. This study aimed to investigate the effects of extracts of halophytes native to Korea on oxidative stress and to determine whether they exert inhibitory activity against biofilms, which are major pathogenic factors of infectious bacteria. The Acinetobacter baumannii strain ATCC 17978, a representative drug-resistant bacterium, was used to measure anti-biofilm activity. The results showed that Aster spathulifolius, Carex kobomugi, Rosa rugosa, and Asparagus cochinchiensis exerted strong antioxidant and anti-biofilm effects without affecting bacterial growth itself. The halophytes used in this study are promising candidates for the development of pharmaceutical agents with antioxidant and antimicrobial properties.

  • In this study, we investigated the characteristics of students participating in Science Core high schools classes and their relevance to Positive Experiences on Science (hereinafter, PES), and factors causing PES, presented by the students of Science Core high schools. A total of 20 students and five teachers in four regions across the country participated in the in-depth interview, which were conducted with the focus group of students first, and then in-depth interviews with teachers. Based on the interview results, we explored teaching and learning experiences helpful to the PES, assessment experiences resulting in the PES, and ways to support Science Core high schools to enhance their PES. Students and teachers of Science Core high schools argued that students' participation will increase only if they engage in classes while drawing attention within the range that students can understand, students' PES such as scientific interest can be improved through experiments in which students choose topics or design their own exploration process, science competencies such as science problem solving ability and scientific thinking ability should be developed through exploratory experiment activities that fit the nature of science, etc. In addition, regarding ways to improve and support Science Core high schools to enhance PES, securing science class hours, restructuring the contents of science elective courses, and necessity of maintaining Science Core high schools are suggested. Based on the research results of science high school students' PES, ways to improve the PES of general high school students are discussed.

  • The purpose of this study is to provide some suggestions for future improvement of scientific inquiry activities in Korean elementary science textbook. The modified framework of Lee(2005) and Millar et al.(1998) was used to compare inquiry activities in the Korean and Singaporean science textbooks. The results of this study are as follows: Korean text books have more activities than Singapore's, but both countries have similar time allotment for science classes. In the area of 'inquiry process skill', Singapore is more balanced in 'Basic inquiry process skills' and 'Integrated inquiry process skills' than Korea. Singapore's integrated inquiry rate is also higher than Korea's. Next the results of comparing leaning objectives to scientific inquiry activities shows that Korean text books tend to focus on 'contents objectives', while Singapore's text books focus on balancing 'contents objectives' and 'process objectives'. Korean science textbooks encourage students to communicate the results of experiments but in most case these communication activities are actually not performed. Lastly Korea and Singapore have low degree of openness in inquiry activities. Remarkably 'Suggest questions' are totally conducted by teachers. This study implies that Korean science textbooks should have lower amounts of inquiry activities to accomodate enough time for communication about results. Next we need to make balance not only 'Basic inquiry process skills' and 'Integrated inquiry process skills' but also 'Content objectives' and 'Process objectives'. Lastly we need to make student to be the leader in science classes through encouraging them to plan procedures for experiments and to discover results by themselves.

  • 이 연구는 한국의 산업발전 과정에서 '기술혁신'이라는 개념이 어떻게 변화하며 사용되어 왔는지를 분석하고자 한다. 이를 위해 한국과학기술단체총연합회(이하 과총)의 기관지인 "과학과 기술" 기사에서 등장한 '기술혁신' 키워드를 중심으로 네트워크 분석을 실시하였다. "과학과 기술"은 1968년부터 지금까지 꾸준히 발간되었으며, 과학기술인 뿐만 아니라 정부부처 관계자 및 과학 분야 기자들을 대상으로 하기 때문에 한국 과학기술사회 전반의 동향을 파악하기 위한 사료로서 가치가 높다. 본 연구에서는 1968년 이후 "과학과 기술"에 실린 기사들 중 제목에 '기술혁신' 키워드가 포함된 모든 기사의 전문을 분석 대상으로 출판 이후부터 현재까지의 기간을 세 구간으로 나누어 '기술혁신'과 동시출현하는 키워드들의 변화 양상을 분석하였다. 이와 같은 분석을 통해서 이 연구는 다음과 같은 결과를 도출하였다. 첫째, 기술혁신 개념은 1970년대와 크게 다를 바 없이 지금까지도 여전히 국가 주도의 산업 발전을 위한 요소로 이해되고 있었다. 둘째, 그럼에도 불구하고 공업, 생산에 국한되어 있던 기술혁신 개념은 1980년대를 거치며 다양한 연구개발 분야 및 이해관계자들을 이어주는 키워드로 변화하였다. 본 연구는 키워드 네트워크 분석을 통해 한국 기술혁신 논의의 변화 양상을 제시하였다는데 의의가 있으며, 연구 결과는 향후 한국적 맥락을 기반으로 한 기술혁신정책의 방향성을 모색하는데 활용될 수 있을 것으로 기대된다.

  • The purpose of this study was to propose for efficient selection with observation and nomination system and efficient operation of Convergence Science class in a Science Institute for Gifted Youth attached in university. For this purpose, we analyzed the result of entrance exam with observation and nomination system, and the correlation between enterance exam score and achievement to perform at the Convergence Science class. As a result, despite observation and nomination system is highly dependent on observers and recommenders, they have very different perspectives each other. In addition it was founded that selection and education process after admission is inconsistent.
