Various methods for detecting changes in response behaviors of indicator specimens are presented for monitoring effects of toxic treatments. The movement patterns of individuals are quantitatively characterized by statistical (i.e., ANOVA, multivariate analysis) and computational (i.e., fractal dimension, Fourier transform) methods. Extraction of information in complex behavioral data is further illustrated by techniques in ecological informatics. Multi-Layer Perceptron and Self-Organizing Map are applied for detection and patterning of response behaviors of indicator specimens. The recent techniques of Wavelet analysis and line detection by Recurrent Self-Organizing Map are additionally discussed as an efficient tool for checking time-series movement data. Behavioral monitoring could be established as new methodology in integrative ecological assessment, tilling the gap between large-scale (e.g., community structure) and small-scale (e.g., molecular response) measurements.

Purpose: This study evaluates the ability to improve the economic welfare of rural communities in Indonesia by using the inequality measures of the distribution of information between leaders and their people as a variable that weakens the capacity of increasing the welfare. Research Design, Data, and Methodology: The research designed by developing an instrument using data validity and reliability testing. Before, primary data collected through interviews, questionnaires, observation, and documentation on the selected respondents. Then, the research method used is mixed methods research, in which quantitative and qualitative methods combined. Result: The finding from this study is that there is an inequality measure in the form of a high gap between the score of information distribution obtained by the village government compared to the score of the community, which has led to the welfare of the village which is still at a moderate level and not ready to become a prosperous society. Conclusion: The weakness of the village community is related to two things, namely the behavior and knowledge of the community about the issues, so the implication is that there must be a strong effort from the central government to ensure that technology is more evenly distributed to all villagers.

본 연구는 교과 간 연계·융합 수업자료 개발의 필요성이 높아지고 있음에도 고등학교에서 관련 수업 자료 개발 빈도가 적다는 선행연구의 연구 결과에 근거하여 수학과 정보 과목의 연계·융합 수업자료 개발 과정 및 결과물을 제시한 연구이다. 특히 본 연구는 동일한 교원학습공동체 프로그램에 참여한 6명의 교사들이 수학과 정보 교과 간 연계·융합 수업자료로서의 적합성과 현장 수업 적용 가능성이 높은 자료 개발을 목표로 논의한 과정들에 대한 정보를 담고 있다. 자료 개발 절차에 따라 주제기반 설계 모형을 적용하여 자료를 개발하였으며, 선행연구와 교원학습공동체 구성원의 합의 결과를 반영하여 100분 블록 수업 시간 동안 수학과 정보 과목의 교사가 함께 수업을 진행할 수 있는 수업 자료를 개발하였다. 개발한 자료는 사회적으로 이슈가 되었던 문제상황을 두 과목의 연결고리로 삼아 학생들이 수학적 모델링과 코딩을 통한 문제해결을 경험할 수 있는 자료이다. 개발된 자료는 '개발 자료를 현장에 적용하기에 타당한 자료인지 살펴보고 적용 실천성을 높이기 위하여' 현장 교사를 대상으로 CVR 검증을 통하여 검증을 하였으며, 그 결과를 반영하여 최종 개발된 수업 자료를 지도안 형태로 제시하였다. 또한 자료 개발 과정에서 개발자들의 경험한 시행착오와 고민도 함께 기술하여 현장 연구자들의 관련 연구 수행에 기초가 될 수 있는 정보를 제공하고자 하였다. 이러한 연구 결과는 수업자료 개발 모형이 실제 수업에 적용가능한지 탐색할 수 있는 실증적인 자료로서의 가치를 가지며, 이들 자료의 축적은 이론적인 수업 모형과 실제적인 현장 수업 사이의 선순환적인 관계 구축에 도움이 될 것으로 보인다.

Background: Bojungikgitang is one of the most common herbs in oriental medicine. Principally, this medicine heals illness from overwork and stress. Therefore, it is frequently used in the ancient community. Because of insufficiency in data, objective judgements are difficult in remedial effects by Bojungikgitang. In order to make objectivity diagnose data, this research is developed. Purpose: The aim of the research is to make questionnaire for the medicine and the objective is to sell to the public from the local clinic. Methods: The questionnaire which includes symptoms and signs for diagnose of Bojungikgitang is studied by the Delphi method and average value. Results: By the Delphi method and average value, 25 Items of questionnaires are choosen for the research. Conclusions: Further research is necessary for modification of questionnaire by statistics and certification by clinical trial. The statistics and verification by clinical trial is necessary with modification for further research.

The present paper deals with the problem of nonselective harvesting in a partly infecte prey and predator system in which both the suseptible prey and the predator follow the law of logistic growth and some preys avoid predation by hiding. The dynamical behaviour of the system has been studied in both the local and global sense. The optimal policy of exploitation has been derived by using Pontraygin's maximal principle. Numerical analysis and computer simulation of the results have been performed to inverstigate the global properties of the system.

Direct-to-consumer (DTC) genetic testing is a controversial issue although Korean Government is considering to expand DTC genetic testing. Preventing the exaggeration and abusing of DTC genetic testing is an important task considering the early history of DTC genetic testing in Korea. And the DTC genetic testing performance or method has been rarely reported to the scientific and/or medical community and reliability of DTC genetic testing needs to be assessed. Law enforcement needs to improve these issues. Also principle of transparency needs to be applied.

The rapid advances in genetic knowledge and technology raise various, sometimes unprecedented, ethical dilemmas in the scientific community as well as the public realm. To deal with these dilemmas, the international community has prepared and issued ethical standards in various formats. In this review, seven international standards regarding genetics and genomics will be briefly introduced in chronological order. Critical reflections on them will not be provided in this review, and naturally, they have their own problems and shortcomings. However, a common set of the principles expressed in them will be highlighted here, because they are still relevant, and many of them will be more relevant in the future. Some of the interesting contents will be selected and described. After that, the morality of one recent event related to whole-genome sequencing and person-identifiable genetic data will be explored based on those international standards.

Taxonomic identification is fundamental to all microbiology studies. Particularly in metagenomics, which identifies the composition of microorganisms using thousands of sequences, its importance is even greater. Identification is inevitably affected by the choice of database. This study was conducted to evaluate the accuracy of three widely used 16S databases-Greengenes, Silva, and EzBioCloud-and to suggest basic guidelines for selecting reference databases. Using public mock community data, each database was used to assign taxonomy and to test its accuracy. We show that EzBioCloud performs well compared with other existing databases.

Childhood obesity has rapidly increased worldwide and is one of the most serious health problems in this age group. In order to prevent and manage childhood obesity, we developed a nutrition education website. The website consisted of three parts. The first part was made for self-assessment with regard to obesity index, dietary habits, food frequency, dietary attitude, nutrition knowledge, nutrient intake, energy expenditure, and the stage of behavioral change, and tailored messages and advice according to the assessment results. A total of 612 real-size food photos as well as a nutrient database of 3,346 foods and 541 dishes were created to help children estimate nutrient intakes accurately. In addition, an energy expenditure database of 156 activities for children was established to calculate calorie consumption. The second part was made for setting long-term and short-term goals and keeping track of the changes in energy intake and expenditure in one's own page. The third part was made for education. Various types of nutrition information were provided; texts, pictures, calculators and games. The readability and design of the website were evaluated by 46 obese children. Usefulness, design and readability of the website were found to be desirable for children. This website is expected to be used by an obese child alone or with parents or nutrition teachers in order to control body weight through healthy dietary habits and physical activities. In addition, a non-obese child can also use this website for maintaining healthy dietary habits and preventing obesity.

본 연구는 국내 메이커 운동의 현황을 파악하고 메이커 커뮤니티 참여를 중심으로 메이커 운동의 활성화 방안을 모색하는데 목적이 있다. 이를 위하여 한국과학창의재단에서 10대부터 50대 사이의 일반인 대상으로 실시한 '2018 하반기 국내 메이커 운동 실태조사' 자료를 분석하였다. 분석결과, 첫째, 국내에서 메이커 운동에 관한 인지도와 메이커 관심 및 참여 의도는 아직까지 높지 않았다. 둘째, 메이커 커뮤니티 참여자와 비참여자 사이에 메이커 인지도 및 메이커 활동에 유의한 차이가 있는 것으로 나타났다. 셋째, 메이커 커뮤니티 참여와 메이커 오리엔테이션 사이의 긍정적인 관계에서 메이커 활동 동기들(즐거움, 스트레스 해소, 자신의 아이디어 표현, 비용 절감, 사회적 인정)의 다중병렬매개효과를 확인하였다. 마지막으로, 연구 결과를 바탕으로 메이커 커뮤니티 참여를 활용한 국내 메이커 운동의 활성화 방안을 제안하였다.
