In this study, we fabricated nickel oxide thin film for lithium based electrolyte using sol-gel method. This film was deposited by dip-coating method with mixed solvent of DameH (N,N-dimethylaminoethanol) and DI water. As changing the ratio between DmaeH and DI water, nickel oxide thin film was presented in different charge density and optical transmittance because they were shown various thickness. It was accounted for changing viscosity and density by the ratio of DmaeH and DI water. The thin film synthesized with 1 : 1 ratio of DmaeH and DI water was expressed best electrochromic performance in lithium based electrolyte, because of thick thickness but porous structures.

The purpose or this study was threefold: 1)) to produce the optimum scale of small schools according to the economies of scale, 2) to grasp the consolidation and the related factors of small schools, and 3) to discover the economical approach utilized in the consolidation of small schools. Review of literature and empirical analysis were the major reseach method used for this study. Literature review was used to gain an understanding of the economies of scale as well as the optimum scale of small schools. Empirical analysis was utilized 「or analyzing consolidation and related factors of small schools. Additionally, statistical techniques such as ANOVA analysis, correlation analysis, and regression analysis were employed according to the characteristics of the variables. The summary of findings are as follows: First, number of classes were inverse proportion to the educational cost per student. The average operational cost per student was low in schools with more classes. whereas the cost was high in schools with fewer classes. Therefore, the standard for the distribution of educational cost should be based on a cost per student basis. Second, the size of the teaching staffs were significantly related to the average operational cost per student. The average operational cost per student was low in schools with larger teaching staffs, while the cost was high in schools with smaller staffs. This fact should be considered carefully when allocating teaching staffs. Third, the relationship between the number of students versus the average operational cost was studied for 5 styles of school groups. It was discovered that schools with 1-10 students had the highest average operational cost while schools wi.th over 101 students had the lowest. Therfore, the consolidation of these smaller schools should be considered to decrease the operational costs of these schools. Fourth. the number of classrooms was inverse proportion to educational costs. This could contribute to the distribution of operational cost which was not based on classroom number. Fifth. it was found that buildings of 60 years or older shared the highest operational cost. On the other hand. newer buildings had the lowest operational cost. The operational cost in older school buildings was because these schools also had smaller student populations. Sixth operational cost differed according to school location Schools located on islands had the highest operational cost while urban schools had the lowest. Seventh, operational cost was affected by distance. Schools located within 1Krn shared the least operational cost while schools outside 4km shared the largest cost. Therefore schools located in longer distance should be consolidated to reduce operational cost. In order to determine the optimum scale of small schools, multiple regression analysis was utilized using crucial independent variables. It was detern1ined that the optimum size of small elementary schools is 12~i students. The optimum size for small secondary schools was found to be 175 students. The related factors in the consolidation of small schools were separated from environmental factors such as geography and the community. Numerous variables were determined from the related factors. The relationship between the related factors and average operational cost was analyzed through regression analysis to determine that the variable relating to student population size had the greatest effect. Other significant variables to the number of classes, teaching staff size. school location, and the public opinion of residents. Therefore. the decision to consolidate small schools should be based on the variables discovered through related factors analysis.

The purpose of this study is to analyze high school student’s brain activity of the process of selfregulation during performing phylogenetic classification task. For this study, their brain activity in the selfregulation was measured using fNIRS when the phylogenetic classification task to find the closest relative to a whale was presented to the students. Self-regulation were classified into five types based on the data with fNIRS, think-aloud, and post-interview. Then, the difference in brain activity of students in self-regulation type 1 and self-regulation types 2 to 5 was analyzed. The results of the study were shown a significant brain activity in FP and DLPFC from types 2, 4, and 5 of conflict-induced self-regulation. This shows that conflict, goal-oriented thinking, and the use of working memory to gain an equilibrium occurred after discovering the difference between whales and sharks. Type 3 was shown no significant brain activity, which means that logically consistent thinking is not involved in the process of mindchanging. Self-regulation types 4 and 5 were shown some significant activities in VLPFC and OFC. In the accommodation process, it can be seen that not only the uncertainty about the problem is recognized, but also the meaning classification work is performed to grasp the meaning of visual data and evaluate the value of alternative schemas they created. Based on interview data and fNIRS brain activity data, this study suggests that if education is conducted with active feedback from teachers, the effect of learning system classification will be further enhanced.

박선하(Park, Sun Ha),김해동(Kim, Haedong) 학습자중심교과교육학회 2019 학습자중심교과교육연구 Vol.19 No.18

본 연구는 학술적 영어 듣기를 하며 노트 필기를 실행 한 대학생 학습자들이 영어능숙도에 따라 노트 필기의 양상에 차이를 보이는지와 노트 필기 행위 자체에 대한 인식에 차이가 있는지를 파악하였다. 본 연구의 대상자는 40명의 대학교 1학년생이 고, 이들은 16주 한 학기 동안에 4주, 9주, 14주의 3회에 걸쳐 영어 강의를 들으면서노트 필기를 시행하였다. 참여자들은 사전 영어 능력 시험 점수에 따라 각 20명의 상위와 하위 집단으로 나누어 졌다. 반복측정 분산분석 결과 두 집단 모두 총 단어, 내 용어, 핵심 내용어는 시간이 경과함에 따라 훈련에 따른 질적인 개선을 보였다. 기호와 번호 붙이기, 축약어는 상위 집단이 유의미한 정도로 자주 사용을 하였으나 시간의 변화에 따른 유의미한 변화는 주목되지 않았다. 14주차에 실시된 면담을 통한 인 식 조사 결과 상위 집단과 하위 집단 학습자들 모두 학술적 영어 듣기에서 노트 필기는 학습한 바를 복습하고 듣기 시험 준비 연습을 위해서 필요하다고 서술하였다. 듣기와 동시에 노트 필기하는 것에 있어서 어려움으로는 상위 집단 학생들은 노트 필기 시간이 부족한 것을, 하위 집단 학생들은 자신의 청취력의 부족을 언급하였다. 본 연구의 시사점은 학술적 영어 듣기를 하며 노트 필기를 시행할 경우 교사는 학습자 영어 수준에 맞추어 개별화된 노트 필기 전략을 지도할 필요가 있다는 것이다. This study aimed to find out whether college students who took notes while listening to academic English showed differences in note-taking aspects depending on their proficiency in English and whether there were differences in their perception of the note-taking activity itself. Forty freshmen participated in the study. They took a 16-week English class and wrote notes three times: the fourth, ninth, and fourteenth weeks. They were divided into upper and lower groups according to their scores on the pre-English proficiency test, and their note-taking was identified by the following areas; total words, content, key words, symbols and numbers, and frequency of abbreviations. The frequency of each criterion was checked by repeated measures ANOVA. The results of the analysis revealed that there is a significant difference depending on the groups and time respectively in the frequency of the total number of words, content and key words, but the interaction of the groups and time is not shown. However, only difference between the groups is significant in the area of the frequency of symbols and numbers, and the frequency of abbreviations. During the interview, the learners stated that in academic English listening, note-taking was necessary for reviewing what they had learned and preparation for listening tests. The upper group mentioned that the difficulty of note-taking while listening was due to the lack of time, whereas the lower group mentioned their lack of listening skills. This study suggests that teachers need to consider learners’ individual differences while teaching note-taking strategies.

유성종,임주완,박선하,원호연,성영은,Yoo, Sung-Jong,Lim, Ju-Wan,Park, Sun-Ha,Won, Ho-Youn,Sung, Yung-Eun 한국전기화학회 2007 한국전기화학회지 Vol.10 No.2

[ $Li_+$ ]를 기반으로 하는 비수용액 전해질에서 Prussian blue가 degradation이 없이 구동할 수 있도록 소재를 design하고 제조하여 전기화학적 변색특성을 연구하였다. Prussian blue는 ITO가 코팅되어 있는 유리판위에 일정전류-전착법으로 코팅을 했고, 이 때 사용된 코팅 용액은 $FeCl_3,\;K_3Fe(CN)_6$을 deionized water에 녹이고, HCl, KCl, LiCl을 각각 넣었다. 전기화학적 변색특성을 비교하기 위해 continuous와 pulse potential cycle 하는 동안 transmittance 변화를 in-situ He-Ne laser를 이용하여 측정하였고, electroactive layer thickness를 통해 degradation된 정도를 실험하였다. The durability problem of Prussian blue in non-aqueous $Li_+$-based electrolytes has been due to the degradation of the Prussian blue electrode matrix during the insertion/extraction processes by $Li_+$. In this work, we designed and synthesised the Prussian blue without reducing the electrochromic performance in non-aqueous $Li_+$-based electrolytes. Prussian blue was electrodeposited on a glass which has ITO coating, and the coating solution is a mixture solution of $FeCl_3\;and\;K_3Fe(CN)_6$ with deionized water added HCl, KCl, and LiCl, respectively. The durability of Prussian blue was evaluated by an in-situ transmittance measurement during a continuous and pulse potential cycling test, and measured by electroactive layer thickness due to evaluating the degradation.

장애인 활동보조서비스제도의 분석 및 개선방안

이종복(Lee Jong-Bok),박선하(Park Sun-Ha),정하선(Jung Ha-Sun) 한국복지행정학회 2008 복지행정논총 Vol.18 No.2

보건복지부는 2007년 4월부터 최중증 장애인을 대상으로 장애인 활동보조지원사업을 실시하게 되었다. 그러나 자립생활 패러다임 이념 적용으로 시행된 활동보조지원사업은 자립생활 관련 사업의 성장과 발전에도 불구하고 장애인 개개인의 욕구에 부응한 질 높은 서비스를 제공할 수 있는 수준에는 미치지 못하고 있다는 평가를 받고 있다. 본 연구는 장애인활동보조서비스 제도의 현황을 분석하고 이를 개선할 수 있는 방안을 제시하는데 그 목적을 두고 있다. 지금까지 장애인 활동 보조 서비스제도를 분석한 결과를 토대로 그 개선 방안을 제시하면 다음과 같다. 첫째, 수급대상에 있어 장애 유형별 서비스 선정 기준 및 인정시간별 등급기준 제고하여야 하며, 둘째 소비자 중심의 전달체계를 구축하여야한다. 이것은 장애인의 선택권과 장애인 참여의 확대되는 방향으로 제정․운영 되어야 함을 의미한다. 셋째 예산 확대와 효율적 운영을 도모하고, 중개기관 및 활동보조인 지원이 확대되어야 한다. 이러한 재정 지원은 서비스를 실시하는 중개기관의 부담을 낮춰 서비스의 질적 향상 노력을 유도할 것이라 예상된다. 그러나 자립생활능력 향상을 위한 장애인의 선택권과 자율성을 극대화 방법은 활동보조지원사업을 확대하고 정책을 강화해야 함을 제언하는 바이다. Ministry of health & welfare has carried out personal assistant service program for the most significantly disabled people since April, 2007, based on the independent living paradigm. Despite the growth and development of programs related with independent living, however, personal assistant service program is being evaluated that it hasn t reached the level that can provide disabled people with high quality services enough to satisfy the needs of each person. This study is intended to review on the present condition and problems of personal assistant service program to improve disabled people s independent living skills comprehensively, and then to suggest plans for improvements. Consequently, the current personal service program needs to reconsider a standard to choose a suitable service per type of disability and rating standard per time service delivery system. It means that personal assistant service program needs to be established and operated disabled people s right of choice and social participation can be expended. Third, a budget expansion and effective operation need to be promoted. Furthermore, the support on intermediary agencies and personal assistants should be expended. It s expected that such financial support might lighten the burden on intermediary agencies which carry out services, and thereby lead to their efforts to improve services qualitatively. In conclusion, personal assistant service program should be expanded and relative policies should be strengthened so as to maximize disabled people s right of choice and autonomy to improve their independent living skills.
