노영주(Youngju Noh),김재철(Jaechul Kim) 학습자중심교과교육학회 2023 학습자중심교과교육연구 Vol.23 No.8

목적 본 연구는 창의융합형 인재의 정서 핵심역량 하위요인인 행복감, 진로성숙, 창의인성, 시민참여에 따른 잠재계층을 구분하고 잠재계층의 분류에 영향을 미치는 요인을 탐색하고자 하였다. 방법 본 연구의 대상은 대구교육종단연구 1차 년(2017년)에 표집한 3,000명(초4, 중1, 고1 코호트) 중 2020년에 고등학교 1학년에 해당하는 4년 차 학생이었다. 대상자 표집은 유층표집법(stratified sampling)으로 대구광역시를 8개 행정구역으로 나누고 구역 내 학교는 무선표집 하였으며, 표집층 별 학교 수는 전체 학생 수 대비 해당 표집층에 속한 학생 수에 비례하여 결정하였다. 고등학교는 계열에 따라 일반계고, 특수목적고, 특성화고, 자율형 공립고를 구분하여 학생 수에 비례하여 결정하였으며, 최종 남학생 979명(52.5%), 여학생 897명(47.8%) 총 1,876명의 데이터를 분석에 활용하였다. 정서 핵심역량 측정도구는 대구교육종단연구에 사용된 행복감, 진로성숙, 창의인성, 시민참여 관련 총 49문항을 이용하였으며, 영향을 미치는 요인은 개인 요인(3개 요인), 가정 요인(5개 요인), 학교 요인(5개 요인)으로 구분하고 해당 문항을 분석에 활용하였다. 본 연구의 목적을 달성하기 위해 Mplus를 이용하여 잠재프로파일분석을 실시하였다. 결과 잠재계층의 수는 3개로 분류하였을 때 가장 적합한 것으로 확인되었으며, 잠재계층에 영향을 미치는 요인을 분석한 결과는 다음과 같다. 첫째, 개인 요인에서는 자기효능감이 정서 핵심역량에 매우 중요한 영향을 미치는 것으로 나타났다. 둘째, 가정 요인에서는 부모와의 의사소통이 가장 큰 영향을 미쳤다.셋째, 학교 요인에서는 친구의 지지가 가장 큰 영향을 미치는 것으로 나타났다. 특히, 개인 요인에서 자기효능감은 전반적 하위군에 비해 상위군이 월등한 영향을 미치고, 친구의 지지와 협력학습이 교사의 지지보다 더 큰 영향을 미치는 것으로 나타났다. 결론 학교와 교육 당국은 부모⋅자녀의 의사소통과 친구⋅교사의 긍정적 관계의 중요성을 인식하고 이를 위해 잠재계층의 특성에 적합한 맞춤형 프로그램 구안과 적용을 위한 노력이 필요하다고 판단되며 이를 위한 실제적 논의를 통해 학생들의 정서 핵심역량을 함양할 수 있는 효율적 전략 마련과 실천 노력이 지속되어야 할 것이다. Objectives The purpose of this study is to identify the characteristics of each latent classes and to explore the factors affecting the classification of latent classes by sub-factors such as happiness, career maturity, creative personality, and citizen participation as emotional core competencies of talents with creativity-convergence. Methods Among the 3,000 students (cohort of 4th grade elementary school student, 1st grade in middle school, and 1st grade in high school) who were selected in the first year of the Daegu Education Longitudinal Study (2017), the subjects of this study were fourth-year students corresponding to the first year of high school in 2020. The target marking was stratified sampling method, which divided Daegu Metropolitan City into eight administrative districts, and the schools in the area were tabulated wirelessly, and the number of schools in each target layer was determined in proportion to the number of students in the target layer compared to the total number of students. High schools were determined in proportion to the number of students by dividing them into general, special-purpose, specialized, and autonomous public high schools according to their affiliation, and 979 boys (52.5%) and 897 girls (47.8%) A total of 1,876 data were used for analysis. The emotional core competency measurement tool used a total of 49 questions related to happiness, career maturity, creative personality, and civic participation used in the longitudinal study of education, and the factors influencing this were largely divided into individual (3 factors), family (5 factors), and school (5 factors) factors, and the questions were used for analysis. Results The number of latent classes was confirmed to be most appropriate when classified into three, and the results of analyzing the factors affecting the latent classes are as follows. First, in the individual factors, self-efficacy was found to have a very important effect on emotional core competencies. Second, in the family factor, communication with parents had the greatest influence. Third, in the school factor, support from friends was found to have the greatest influence. In particular, in the individual factors, self-efficacy was found to have a superior effect on self-efficacy in the upper group compared to the overall lower group, and the support of friends and cooperative learning had a greater effect than the support of teachers. Conclusions Schools and educational authorities recognize the importance of communication between parents and children and positive relationships between friends and teachers, and for this purpose, it is necessary to devise and apply customized programs suitable for the characteristics of the latent classes. Efforts to develop effective strategies and practice efforts to cultivate students' emotional core competencies should be continued.

As high-resolution and high quality of sound technologies have developed, digital games can express a reality much more thoroughly compared to the past. This study aims to examine how the environments in games affect user experiences according to how well media elements in games reflect a reality as it is. Especially, this research focuses on the auditory components among the several factors that gamers can be affected when playing games. To explore the research question above, this study compared realistic sound game and animation ones by a playtesting experiment. The experiment used a physiological measurement method, EEG to complement the of self-reported measures such as flow, arousal, identification. According to the result of R-MANOVA analysis, flow, identification reveals significant differences between two games by sound realism. In case for identification, interaction effects between gender and sound presence showed significant differences. As for EEG, it showed significant results in mid-β, high-β, γ. Since theses brain waves are known to indicate the concentration degree of a certain activity, it implicates that the more realistic sound effects are, the more strongly users can concentrate on games. This study intends to figure out how sound presence can affect user experiences through comparative experiments and contribute to the validity and methodological elaboration of the sound presence effects using physiological variables.

구리염 수용액에서 알루미늄의 이상 반응 거동을 소재로 한 탐구학습 자료 개발

표준환원전위 차이에 의하면 수용액 속에서 구리 이온과 금속 알루미늄은 자발적인 산화-환원 반응을 일으킨다. 그런데 실험에서 반응을 관찰하면 알루미늄은 질산 구리, 황산 구리 수용액에서 반응하지 않고 염화 구리 수용액에서만 반응한다. 두 가지 수용액에서 반응이 일어나지 않는 것은 알루미늄의 산화피막이 보호막으로 작용한 때문이고, 염화 구리 수용액에서 반응하는 것은 염화 이온에 의한 공식(pitting corrosion) 현상으로 산화피막이 제거되기 때문이다. 반면 아연은 질산 구리, 황산 구리, 염화 구리 수용액 속에서 모두 반응한다. 본 교육 자료는 알루미늄이 서로 다른 구리염 수용액에서 선별적으로 반응하는 원인을 학생들이 직접 고등학교 수준의 화학 지식과 준비물만으로 가설을 설정하고 간단한 실험으로 증명까지 할 수 있음을 보이고, 학생들에게 적용할 수 있는 탐구활동 학습 자료를 제공한다. 이 활동을 통해 학생들이 과학의 핵심인 실험적 증명 과정을 즐겁게 체험할 수 있을 것으로 기대한다.

Detection of Radiation - Induced Hydrocarbons in Green, Black and Oolong Teas

Tusneem Kausar,Jungeun Lee,Jungeun Noh,Youngju Kwon,Joong-Ho Kwon 한국식품영양과학회 2004 Preventive Nutrition and Food Science Vol.9 No.3

Hydrocarbons induced by gamma-irradiation of green, black, and oolong teas were analyzed to determine whether the hydrocarbons can be used as markers for detecting post-irradiation of these teas. The samples were irradiated at 0, 2.5, 5, 7.5, and 10 kGy. Detection was attempted by extracting fat from the teas, separation of hydrocarbons with florisil column chromatography, and identification of hydrocarbons by gas chromatography-mass spectroscopy (GC-MS). Concentration of hydrocarbons increased with the irradiation dose. The major hydrocarbons in irradiated green, black, and oolong teas were 1-tetradecence (14:1), pentadecane (15:0), 1,7-hexadecadiene (16:2), 1-hexadecene (16:1), 8-heptadecene (17:1), and heptadecane (17:0). Radiation-induced hydrocarbons in teas were 1,7- hexadecadiene and 8-heptadecene. These compounds were not detected in non-irradiated samples, so the hydrocarbons (16:2, 17:1) can be used as markers for detecting post-irradiation of the teas. Furthermore, detection of hydrocarbons after 12 months storage at room temperature remains a suitable method for identifying irradiated teas.

This study was conducted to evaluate a visual surveillance system. The advancement of recording technology and network service make it easy to record and transfer the videos. Moreover, progressed recognition technology help to make a distinction each other. Cows show distinguishing behaviors during their estrus period. The mounting is one of the behaviors. The result was different depending on the breed of the cows and the size of the farm. In the case of Korean native cattle, the estrus detection rate was 71.15%, however, dairy cows, the estrus detection rate was 39.38%. At the farms having below 6 modules, the estrus detection rate was 87.41%. On the other hand, at the farms having over 6 modules, the estrus detection rate was 77.78%. With the proper progress, the visual surveillance system can be used to detect heat detection.
