  • This study sought to examine the factors influencing clinical competence of dental hygienists. A survey on burnout, critical thinking tendency, self-esteem, self-leadership, professional self-concept and clinical competence was conducted with 254 dental hygienists using self-administered questionnaires. Correlation analysis was performed between study variables, and linear regression analysis identified factors influencing clinical competence. To determine a causal relationship among these factors, a path analysis was conducted at the 0.05 level of significance. Relationships among research variables showed significant positive correlations (p<0.01). Self-esteem, self-leadership, and professional self-concept were found to influence clinical competence (p<0.01). A causal relationship was also found among variables influencing clinical competence. Burnout and critical thinking had an indirect effect, whereas self-esteem, professional self-concept, and self-leadership had both direct and indirect effects. In conclusion, important factors influencing clinical competence of dental hygienists include self-esteem, self-leadership, and professional self-concept. Based on these findings, programs to enhance clinical competence of dental hygienists should be developed.

  • In the universities of U.S.A., Criminal Justice is the interdisciplinary study of the institutions and policies that constitute the criminal justice system, as well as theories of human behavior and philosophies of justice related to the maintenance of social order, the control of crime, and the achievement of a just society. There are 103 American Universities have Criminal Justice department and they provide about 180 differents courses as a pre-requisition or optional subject in the major. The most 10 courses that those colleges adopted are Introduction to Criminal Justice, Criminal Law, Criminology, Criminal Procedures, Research Methods in Criminal Justice, Criminal Investigation, Juvenile Justice, Terrorism, Ethical Issues in Criminal Justice, Introduction to Psychology or Introduction to Sociology. Also, 10 fields more important in the major if we group together similar courses those are Criminal Justice and Procedures Sequences, Law, Justice and corrections, Theory and Methods Sequences, Homelend Security and Security Operations, Forensics and Cybercrime, Management and Administration, Police, Race and Ethnicity, General Requirements, Other Social Science Fields. The combined degree program leading to Bachelor of Arts Degree in Criminal Justice and Master in Public Administration provides a concentration in criminal justice, management, administration, and leadership. They have big different courses between USA and Korea event though they have similar educative goal and way of approach to the target in the major.

  • The purpose of this study is to identify secondary chemistry teachers' abilities to carry-out experiment lesson successfully. As far as the research method is concerned, literature reviews, analyses of abilities to carry-out experimentation from science textbooks, and a survey of science teachers' perceptions of experimental ability were employed along with the progressive discussions among the authors. In order to identify secondary chemistry teachers' abilities to carry-out experimentation, we divided the experiment lesson into three stages of preparation, conduct and arrangement, and management of lab, and added the stage of safety. Each stage is classified into sub-areas, and the sub-area consists of subordinate elements. The safety stage was included separately to emphasize the importance of the safety issue in lab and experimental activities. The secondary chemistry teachers' abilities to carry-out experimentation are the abilities to perform experiments in person, presupposing the instruction of experiment, and can be featured with the use of reagent and measuring instruments, the preparation of sample, designing experiment, correct experimental habit and skillfulness, data processing, analysis and reasoning, and management of lab and safety.

  • The purpose of this study was to evaluate the tobacco cessation activities of the dental staffs in Wonju city. All 137 subjects were surveyed by structured questionnaire with convenience sampling. The distribution and correlation of attitude, behavior, and intervention were evaluated by both frequency test and ANOVA test. 75.2% of total subjects responded that the dental staff should give a model through prohibition of smoking and 66.5% responded that tobacco cessation activities should be responsibility of the dental staff. Tobacco cessation counsel was performed by little but with positive attitude. Advice method of tobacco cessation was used to counsel on tobacco cessation (68.6%). The dentists (48.2%) and dental hygienists (23.4%) were responded adequate for the tobacco cessation counselor, however, it was shown that the dentist had lower level of attitude about tobacco cessation than dental hygienist (p<0.01). The dental staff needs to participate in the tobacco cessation counseling program more regularly and actively. In order for the dental staffs gets the counsel effectively and intervene with tobacco cessation, it is essential that the education of tobacco cessation is integrated in dental school. Furthermore, it is necessary for the dental staffs to take continuing education for more effective understanding of tobacco cessation.

  • Recently, many advanced countries have used original ICT tools in their educational courses. But Korea didn't have any effective origin ICT tools in our mathematical education, compared with other countries which have developed various tools, for examples, Web-Mathematica and HP Calculator. Although we have the advanced IT environment, the educational environments in mathematics using ICT seems to be not promising. In this paper, we suggest a new mathematics education tools in ICT and the internet environments in Korea, and a teaching and studyingmodel for the teachers, students and classrooms. It is based on the Sage-Math and RPG. Sage-Math which is the software based on the web and RPG(Random Problem Generator) will give a good answer for the future of Korean mathematics ICT education.

  • Environmental designers in Korea have shown interests in Environomental Psychology and Behavior Studies (EPBS) since 1970's. However, many designers, who have expected a great deal of contribution from the EPBS, have disappointed due to their overexpectation and misunderstanding on the EPBS. This study intends to analyse the nature of the EPBS and to investigate the potential contribution of the EPBS to the field of environmental design. The EPBS are able to help designers by providing scentific data in each stage of the design process. Further, most design theories and principles are based on the findings of the EPBS. Thus the development of the EPBS has great potential of contribution to the development of design theories arid principles Due to the scientific nature of the EPBS, however, the EPBS have difficulties in supplying scientific data within relatively short period, which make most designers impatient. Designers should understand the scientific nature of the EPBS and be patient in expecting usable outcome from the EPBS. Further, Designers should not expect the EPBS give them design soultion itself.

  • 정부지원 R&D 프로그램에 대한 성과평가는 과학기술혁신을 위한 정부투자의 규모가 확대되면서 동시에 그 수요가 증가하고 있다. 본 연구는 국내외에서 시행되고 있는 정부 R&B 프로그램의 성과평가에 대한 체계를 비교분석함으로서 올바른 성과평가의 틀에 관한 시사점을 제공하는데 목적이 있다. 각 프로그램을 비교분석하기에 앞서 성과평가와 관련한 일반적인 이론들을 살펴봄으로써 R&D프로그램에 대한 성과평가가 갖추어야 할 이론적인 체계에 대해 살펴보았다. R&D 프로그램의 성과평가를 위해서는 R&D 활동 자체가 혁신시스템 안에서 수행되고, 집행과정에서 그 효과가 증폭되어 혁신시스템을 변화시킬 수도 있기 때문에 일반적인 정책평가 이론 외에도 혁신시스템 이론을 함께 고려할 필요가 있다. 혁신시스템적 사고방식하에서 올바른 성과평가를 수행하기 위해서는 일반적인 평가기준으로 서 제시되는 적합성, 효율성, 효과성의 각각에 대해 혁신시스템적 기여도에 대한 고려가 충실히 반영되어 있어야 한다. 예를 들어 혁신시스템의 모든 요소들을 포함하는지, 환경적인요인을 고려했는지, 혁신 요소들 간에 형성된 네트워크에 대해 충분한 고찰을 하고 있는지 등이 여기에 해당한다. 실증연구에서는 이러한 것들이 모두 반영되었는가에 초점을 맞춰 각 국가 별 R&D 프로그램에 대한 성과평가를 분석하였다. 분석 대상은 해외와 국내의 주요 R&D 프로그램으로 비교적 성과평가가 활발하게 진행되었던 사례들을 선정하였다. 이러한 평가에 대한 평가, 즉 메타평가를 통해 각 프로그램의 성과평가가 가지는 특성을 밝히고 이들을 비교하여 적절한시사점 이 도출하였다. 이들 사례를 비교 분석한다면 그 결과를 바탕으로 하여 혁신시스템을 고려한 성과평가의 일반적인 모형을 제시할 수 있을 것으로 기대한다. 나아가 추후에 진행될 R&D 프로그램에 대한 성과평가에서도 본 연구에서 제시한 일반 모형을 응용함으로써 조금 더 체계화된 성과평가가 이루어질 수 있을 것으로 기대한다.결과 관점간 가중치의 우선순위가 동일할 경우 현행 평가제도는 연구기관의 의견이 반영되었다고 볼 수 있으나, 검증결과 관점간 가중치가 다르게 나타났다. 또한, 추가적인 분석에서 연구회별 관점의 가중치와 소속 연구기관별 관점의 가중치를 분석한 결과 일부 연구기관에서는 연구회의 가중치와달리 나타났다. 따라서, 현행 기관평가제도는 일부 연구기관의 특성이 충분히 반영되지 않아서 유효한 평가제도로 볼 수 없다고 하겠다. 본 연구의 결과에 따라 출연연구기관의 기관평가지표에 대한 각 지표별 가중치와 지표 문항 개선시 유용한 자료로 활용되리라 본다.로 하기 때문에 원가를 절감할 수 있다.환경현안에 대한 정치경제적 접근을 외면하지 말고 교과서 저작의 소재로 삼을 수 있어야 하며, 이는 '환경관리주의'와 '녹색소비'에 머물러 있는 '환경 지식교육'과 실천을 한단계 진전시키는 작업으로 이어질 것이다. 이후 10년의 환경교육은 바로 '생태적 합리성'과 '환경정의'라는 두 '화두'에 터하여 세워져야 한다.배액에서 약해를 보였으나, 25% 야자지방산의 경우 50 ${\sim}$ 100배액 어디에서도 액해를 보이지 않았다. 별도로 적용한 시험에서, 토마토의 경우에도 25% 야자지방산 비누 50 ${\sim}$ 100배액 모두 약해를 발생하지 않았으나, 오이에서는 25% 야자지방산 비누 100배액에도 약해를 나타내었다. 12. 이상의 결과, 천연지방산을 이용하여 유기농업에 허용되는 각종의 살충비누를 제조할 수 있었으며, 방제가 조사결과 진딧물, 응애 등 껍질이 연약한 곤충의 방제에 효과적인 것으로 나타났다. 따라서 제조된 살충비누를 활용하면 환경친화적인 해충방제가 가능하다고 판단되었다.능을 충진시켜서 암세포를 파괴시킨다. 또한 콜로니 자극인자인 사이토카인을 생산시켜서 면역담당세포의 신생을 촉진시키기도 하며, 암의 화학요법과 방사선 요법으로 저하된 백혈구를 회복시키는 역할을 한다. 따라서 최근의

  • This study was conducted to evaluate the effect of several fungicides and growth regulators on rice seedling growth and damping-off in seedling boxes for machine transplanting. Fungicide treated plots were better seedling growth, shoot regrowth, rooting ability, change of moisture content than those of nontreated plot. Metalaxyl application of Samgangbyeo and SF8002 application of Nagdongdyeo apparently increased plant height, length of the third leaf and fourth leaf. And metaiaxyl application highly increased dry weight. Fungicide treated plots were highly effective in reducing the incidence of damping-off. Benzyladenine application of Samgangbye and $GA_3$ application of Nagdongbyeo apprently increased plant height. But ABA application highly decreased plant height. ABA application and aCE application resulted in highly increased rooting ability. Fungicide and $GA_3$ treated plots, Metalaxyl and growth regulator treated plots resulted in highly increased plant height. I soprothiolane and growth regulator treated plots resulted in decreased plant height. Dachigaren and lAA treated plot apprently increased dry weight and shoot dry weight/plant height. Fungicide and growth regulator treated plots were highly effective in reducing the incidence of damping-off.

  • The purpose of this study was to explore the learning progression of logical thinking in acid and base chemical reactions and to evaluate its validity. For this purpose, we collected 387 participants in 9 schools of elementary, middle and high schools nationwide. The questionnaire developed in this study was composed of nine items. The questionnaire presented the acid and base reactants and products, and the students pictured their thoughts on how these substances change, and answered the reasons of their thoughts. Situation contexts of the questionnaire were divided into two groups: one kind of solute dissolved in a solvent, and two kinds of solute dissolved in a solvent. In this study, six levels of learning progression were assumed by combining material conservation logic, combination logic, proportion logic, and particle number conservation logic. By analyzing the data, Infit and Outfit values of Person reliability, Item reliability, MNSQ and ZSTD were obtained from the Rasch model. As a result of the analysis of data, it was found that lower levels of learning progression prevailed up to the younger grade students till $8^{th}$ grade. The higher levels of learning progression(Level 2~Level 5) prevailed up to the older grade students. However, higher levels of learning progression dropped sharply in Grade 12. The 5 level of learning progression was very low in all grades, and $9^{th}$ grade had highest percentage of students belonging to the 5 level. Interpretation of these unusual results suggests a future research related to explanation differences of textbooks.

  • This study proposes a STEAM (Science, Technology, Engineering, Arts, and Mathematics) program for career exploration of middle school students. The proposed program utilizes VR (Virtual Reality) for new digital technology and webtoon as a popular cultural element. It enables the students to investigate promising fields and experience them virtually for themselves. We design the program based on the 2015 revised curriculum, which enhances the learning effects with existing subjects. In particular, the program provides a hybrid education to combine contact and untact classes considering the COVID-19 situation. The educational goal of the proposed program is to improve creativity and convergence capability. Specifically, it aims to prepare an educational foundation that integrates new digital technologies into education and applies the programs to school education fields. To prove the effectiveness of the developed program, we applied the program to the second graders of A middle school located in Seoul. We expect that the proposed program helps students learn how to utilize new digital technologies and explore future career paths.
