        To achieve the high efficiency for a comminution of sericite powder with a plate structure, the sericite powder was milled in 1M KNO₃ solution for 0, 0.5, 1, 2, 5, 10 h and compared with the addition of distilled water. It has been found that the mean diameter of the grinded particles decreases until the milling for 1 h, however, increases after l h due to the agglomeration between fine particles The sericite powder milled with 1 M KNO₃ solution for 1 h shows the smallest particle size of 19㎛ and in the case of distilled water, it shows the smallest particle size of 2.4㎛.

        과학고등학교 교사들의 영재교육에 대한 신념과 실제수업의 관련성

        노희진,김동욱,백성혜,Noh, Hee-Jin,Kim, Dong-Uk,Paik, Seoung-Hey 대한화학회 2008 대한화학회지 Vol.52 No.2

        이 연구에서는 과학고 교사들의 영재교육에 대한 신념과 실제수업의 관련성을 알아보았다. 이 사례 연구의 자료는 한 과학 고등학교에 근무하는 세 명의 과학교사로부터 얻었으며, 면담과 수업관찰 등 질적 연구 방법을 통해 수집하였다. 과학고 운영과 교사의 수업에 관련된 다양한 자료도 함께 수집되어 상호검증을 통한 일 치도 확인 방법으로 자료 분석이 이루어졌다. 연구 결과, 과학고 근무경력이 가장 많은 교사는 교사중심의 신념 을 가졌고, 실제 수업 역시 교사 중심으로 운영되었다. 또한 과학고 근무경력이 가장 적은 교사는 학생 중심의 신 념을 가졌고, 실제 수업 역시 학생 중심으로 운영되었다. 반면 과학고 근무경력이 중간인 교사는 학생 중심의 신 념을 가졌으나, 실제 수업은 교사 중심으로 운영되어 신념과 실제 수업의 불일치를 보여주었다. 이러한 연구 결 과로부터, 학교 문화가 교사의 신념보다는 더 강하게 교사의 실제 수업에 영향을 준다는 사실을 알 수 있었다. 과 학고 근무 경력이 많을수록 교사의 신념은 영재교육보다는 대학 입학을 위한 지식 교육을 위한 교사 중심으로 변 화되었다. 이러한 문제점을 해결하기 위하여 과학고 교사를 위한 교사교육 프로그램의 필요성을 제안하였다. This study investigated the relationship between science high school teachers' beliefs of gifted education and classroom practices. The data of this case study were collected from three science teachers who worked in a science high school through qualitative research methods such as interviews and classroom observations. The other various data related to science high school management and the teachers' teaching were collected and analyzed using the constant comparative method. The results of the study are as follows: the teacher of long period in-service experience in science high school had teacher-centered belief, and his classroom practices were matched with his beliefs. The teacher of short period in-service experience in science high school had student-centered belief, and her classroom practices were matched with her beliefs, also. The teacher of medium period in-service experience in science high school had student-centered belief, but her teacher-centered classroom practices were mismatched with her beliefs. From the results, it could conclude that school culture affects on teachers' classroom practices stronger than beliefs. The longer career period of science high school changed easier teachers' beliefs into knowledge education for university entrance examination removed from gifted education. To solve these problems, we suggest the needs of teacher education programs for science high school teachers.

        유역유출 변화에 따른 도암댐 저수지 수질 영향 예측

        노희진,김정민,김영도,강부식,Noh, Hee Jin,Kim, Jung Min,Kim, Young Do,Kang, Boo Sik 대한토목학회 2013 대한토목학회논문집 Vol.33 No.3

        본 연구에서는 도암댐 유역을 대상으로 유역모형과 호소 및 하천모형의 연계를 통해 통합모델링시스템을 구축하였다. 국내 기후 특성상 하절기에 집중되는 강우로 인해 댐의 건설은 홍수조절, 용수확보 및 전력생산 등의 목적에 있어서 불가피하다. 특히 이러한 목적의 댐 형태가 하천과 하천 사이에 위치할 경우에는 연계된 구간을 하나의 유역으로 보고 이를 통합적으로 모의 및 관리 할 수 있는 시스템이 필요하다. 본 연구에서는 도암댐 유역을 대상으로 유역모형인 SWAT 모형을 구축하고 저수지 및 하천의 수리 및 수질 모의를 위해 EFDC-WASP 모형을 구축하였다. 또한 현재 도암댐 상부에서 시범가동 중인 수질개선장치 효율이 반영된 시나리오를 모의하여 통합모델링시스템의 적용성을 검토하였다. In this research, the integrated modeling system by coupling of a watershed model, a reservoir model, and a river model has been constructed in Doam reservoir watershed. Because of domestic climate characteristics, it is inevitable to construct the dam for control of flood, water use, and power production due to the heavy rain in the summer. Especially, when the dam is constructed on the stream for these kinds of purpose, it is necessary to consider this region as one watershed and also to make the integrated system for simulation and management. In this study, SWAT model was constructed for watershed modeling and EFDC-WASP model was constructed for simulating the hydrodynamic and water quality of the reservoir and the downstream in Doam dam watershed. Also, the water quality improvement equipment for demonstration was applied in the upstream part of Doam reservoir, which shows the applicability of the developed integrated modeling system.

        치과위생사의 기본소생술관련 지식 및 수행능력

        노희진,배성숙 대한응급의학회 2012 大韓應急醫學會誌 Vol.23 No.4

        Purpose: The purpose of this study was to evaluate Cardiopulmonary Resuscitation ability and level of knowledge among certain dental hygienists in Seoul and Gyeonggi-do. Methods: We surveyed ability and knowledge of CPR among dental hygienists working at dental offices and dental hospitals located in Soul and Gyeonggi-do from September 18, 2010 to October 16, 2010. Data acquired from dental hygienists who had completed the questionnaire that we designed were used in the analysis. Uni- and bi-variate analysis and Chi-square test were performed using SAS 9.2. Results: According to our findings, among respondents,approximately 14.29% of dental hygienists had a CPR license. Their CPR licenses are affected by working period,job position, and level of education (p<.05). Factors including working period, type of CPR license, and CPR license renewal were indicators of CPR knowledge level (p<.05). Significant differences were observed among dental hygienists with regard to subjective CPR abilities, which is dependent on obtaining a CPR license, CPR knowledge level, and education channel for CPR (p<.05). Conclusion: CPR ability and knowledge level among dental hygienists were not sufficient to save emergency people in the dental clinic. In order to save emergency patients patients, implementation of a CPR education and renewal program for dental hygienists is recommended.

        고흥산 세리사이트의 物性 및 분쇄 특성

        노희진,이종국,서동석 한국자원리싸이클링학회 2001 資源 리싸이클링 Vol.10 No.4

        박판상을 갖는 세리사이트 분말의 분쇄 효율을 향상시키기 위하여 분쇄조제 1 M $KNO_3$ 용액이 첨가된 분말을 시간에 따라 분쇄하였으며, 증류수만을 첨가하여 분쇄한 분말과 비교하였다. 분쇄된 분말의 평균 입자크기는 분쇄시간 1시간까지는 감소하다가 1시간 이후에는 미세 입자들간의 응집으로 증가하였다. 세리사이트 분말에 $1 M KNO_3$용액을 첨가한 경우 1시간 분쇄하였을 때 평균입자크기가 $1.9mu$m로 가장 작게 나타났으며 증류수를 첨가한 경우에도 1시간 분쇄 시 $2.4\mu$m로 가장 작게 나타났다. The Sericite Powder W3S Comminuted in 1 M $KNO_3$solution for 0.5, 1, 2, 5 and 10 h, compared with the addition of distilled water. It has been found that the mean diameter of the ground particles decreases until the comminuting for 1 h, however, increases after 1 h due to the agglomeration between fine particles. The sericite powder comminuted with 1 M $KNO_3$solution for 1 h shows the mean particle size of $1.9\mu$m, and it also shows the mean particle size of 2.4 $\mu$m in case of comminution in distilled water for 1 h.

        『膽大小心錄』の中での狐の性について

        盧熙眞 한국일어일문학회 2003 日語日文學硏究 Vol.45 No.2

        It seems that an anecdote about a fox asserted in TANDAISYOUSINROKU by UEDAAKINARI presents a world different from that of a large majority of human beings where the doctrine of Confucianism and Buddhism, i.e, the concept of good and evil, and right and wrong prevails as the criteria. There is the concept of good and evil, and right and wrong in the world of human beings. Human beings who have the concept of good and evil, and right and wrong of Confucianism and Buddhism judge someone's wrongdoing by considering what kind of will he had when doing such a behavior as the criteria of judgement. Therefore, in some cases they cannot judge his behavior only by the norm with the intervention of humaneness despite the standard of good and evil, and right and wrong. Fox or God that has no concept of good and evil, and right and wrong judges by the results appeared on the surface regardless of man's will. For AKINARI, such animals as fox, dogs, raccoon, wolves and snakes are the ones that repay man for his behavior. In reality, the behavior of fox is the act of man. That is to say, it is a mirror itself. But, if man destroys the mirror to the extent of perfection or kills the fox or snake the mirror cannot reflect man. If the fox or snake does not exist, it cannot retaliate man. AKINARI believed in fox on the basis of his own direct experience saying that "The more you see of fox and raccoon, the more you get to know they take the form of man." in article 13 of the TANDAISYOUSINROKU. The fox and mirror have the same nature in that they reflect objects as they are, and don't have the concept of good and evil, and right and wrong. Nevertheless, Confucianists insist that fox's transformation into man is a rumor or superstition, but, the fox and mirror cannot retaliate man if he has "jyoubusin" which can make God give in to him. In this regard, AKINARI's fox is regarded as very unique and different from that of Confucianists, or a rumor or superstition of those days.
