This study was attempted to improve teaching methods for the education department of a teachers' college. Problems referred to teaching methods of the department were extracted through the analysis of its educational systems. The content of education as well as such variables as students and professors were examined. And then, the tactics and a model for improving the teaching methods of the department were presented on the basis of problems extracted. The devices for solving the problems were discussed as follows : 1) As for the content of education,acadmic structures of each subject have to be facilitated through the rearrangement of educational content,which should be reintegrated according to Starratt's humanistic curriculum model. The devices for fostering the activities of students' scientific inquiry have to be facilitated through the rearrangement of educational content by the Butt's model. 2) As for the student variables,most of the freshmen have difficulties in performing their academic purposes due to the lack of aims and directions of the department in which they are enrolled. Students' expectations need to be controlled by professors for students' adjustment to college life. Especially,students' expectations should be coincided with social expectation. 3) Professor variables are essential to the efficient learning and instruction processes. Thus,professors should concider many relevant variables in planning,implementing and evaluating the instruction-learning processes. The Nodding's teacher competence model provides the frame of references for considering these variables. On the other hand,instruction-learning processes need to be performed in terms of the student-centered learning. De Groot's self reporting model and Kirkpatrick's Maslovian counseling model have significant implications for the planning,implementation,and evaluation of the instruction-learning processes. On the basis of the findings of this study,the tollowing suggestions are in order. 1) The opportunities for academic research and self understanding should be presented to students in developing the instruction-learning processes in order to achieve the purpose of the department. 2) Group and individual guidance are needed to motivate the students and to foster the students' will to learn. 3) The supported research and opportunities for professors' in-service training to improve their teaching methods should be enlarged. 4) Various measures as stated above have to be devised to facilitate the students' participation and creativity. 5) The model of the education department should be applied to other deparments for improving their instruction-learning processes. 6) It is a well known fact that no school is better than the teacher. Thus,professors' continuous efforts should be made to improve the nstrction-learning processes as a student-centered one.

大學生의 思考技能의 診斷과 改善에 關한 硏究 : It's Diagnosis and Improvement

Cognitive psychologists have taken a growing interest in reasoning skills as a primary goal of education. This study was accomplished as a part of elementary research on reasoning skills that have been pointed out as short comings of teaching of thinking. This study was composed of two substudies : one was to explore the ways to analyzing and diagnosing strategies for college students to apply to reasoning and problem solving, and the other was to examine the teachability of a normative strategy of thinking. In the first part of this study, we explored three alternatives to analyze thinking skills : cognitive process analysis, cognitive structure analysis, and cognitive style analysis ; and suggested the integrative use of them in diagnosing the cognitive skill of reasoning and problem solving. Model of cognitive process analysis was to devide the executive process of a specific task into several subtasks or components, measure the amount of effort, response time, and achievement level for each of them, and thereby analyze the strategies of thinking. Model of cognitive structure analysis was to present subject a specific task, instruct him to think aloud those ideas that came into his head during this solution, and analyze his cognitive structure on the base of his thinking-aloud. Finally, model of cognitive style analysis put more stress on tendency in thinking rather than ability in problem solving. In this regard, a alternative presented in this study was to analyze the strategies of thinking according to Baron's cognitive style model, in which process of thinking activity was devided into four phases : search of goal, search of possibility, search of evidence, and use of evidence. For each of them, the amount of time and effort that the indevidual invested and patterns of value that he grant would become criteria for judging the strategies that would become criteria for judging the strategies that he might use in the process of thinking activities for reasoning and problem solving. In result, this should correspond to measure biases on thinking. In general, main biases on thinking could be referred to insufficient search, search biased toward affirmative evidence, and oversensitivity to supporting evidence, which corresponded to compulsiveness vs. reflectiveness, dogmatism vs. open-mindedness, and authoritarianism, from a point of view on cognitive style, respectively. In the second part of this study, we examined the general principles of teaching thinking skills, based on human informations processing, and several training programs that have been developed with the purpose of improvement in thinking and reasoning skills. These programs were discussed into five categories: (1) cognitive operations approaches, (2) heuristics oriented approaches, (3) formal thinking approaches, (4) symbolic facility approaches, and (5) thinking-about-thinking approaches. Within these programs, the expansion of strategies and control of cognitive styles in reasoning and problem solving have become the main targets for improving of thinking skills. Therefore, this study was attempted to develop two training programs―referred to as Problem-Solving Training Program and Reasoning Skill Training Program respectively― for the purpose of improving these skills, and to test the effectiveness of these programs with college students. This study has shown the following facts : 1) It is necessary to teach the basic strategies for solving cognitive tasks of subject matters such as writing and mathematical problem for the purpose of improving thinking skills. 2) It is necessary to change the relatively general tendency in thinking process such as cognitive styles, in parallel with training of strategies. 3) Also, the training programs must consider indevidual defferences in activity parameters such as self-knowledge about problem solving, motivation, belief, etc. These facts seemed to imply the necessity of multi-dimensional approach to training the thinking skills.

Antibacterial Coating of Cellulose by Iso-bifunctional Reactive N-halamine with the Dyeing Process of Reactive Dye

Tong Mu,Nengyu Pan,Yingfeng Wang,Xuehong Ren,Tung-Shi Huang 한국섬유공학회 2018 Fibers and polymers Vol.19 No.11

In this study, we synthesized a novel N-halamine precursor, sulfuric acid mono-[2-(4-[4-chloro-6-(2-[4,4- dimethyl-2,5-dioxo-imidazolidin-1-yl]-ethylamino)-[1,3,5]triazin-2-ylamino]-benzenesulfonyl)-ethyl] ester sodium (TB), which contains two reactive groups of monochloro triazine reactive groups and bis-sulphatoethylsolphone reactive groups. The structure of TB is similar to iso-bifunctional group reactive dyes and could be coated on cotton fabrics by covalent bonds through a reactive dyeing process. The cotton coated with TB was characterized by FTIR and SEM. After chlorination, the treated cotton fabrics showed excellent antibacterial efficacy and inactivated all inoculated S. aureus (ATCC 6538) and E. coli O157: H7 (ATCC 43895) within 1 min of contact. Over 85 % of tensile strength retained both in warp and weft directions after treatment and chlorination. Almost 80 % of active chlorine can be regained by treating with household bleach after extensive washing and long time storage.

The Conceptual Management Framework for Sustainable Fisheries Development

Mu, Yong Tong,Choe, Jung Yoon 한국수산경영학회 2000 수산경영론집 Vol.31 No.1

최근에 지속적 발전(sustainable development)은 환경 정책 분석뿐만 아니라 현대 환경, 생 태 경제학에 있어서 중요한 개념이 되어왔으며, 이 개념은 어업에 있어서 특히 중요한 국제적 이슈(issue)가 되고 있다. 어업은 갱생자연 자원에 입각한 산업으로서 지속적 발전의 길로 가야만 한다. 이것은 1982년 UN해양법 협약(UNCLOS), 1995년 UN 경계왕래성 어족과 고도회유성 어족에 관한 집행협약 (UNIA), FAO의 책임있는 어업(the Code of Conduct for Responsible Fisheries)을 위한 국제규범과 일련의 기술지침서에서 구체적으로 표현함으로써 국제적 합의가 이루어지게 되었다. 지속적 발전의 개념에 대한 심층적인 이해는 어업 관리자가 어업정책의 수립과 평가에 대한 새로운 요소와 기준을 설정함에 있어서 중요한 의미를 부여한다. 이것은 특히, 어업 관리자(정부와 단체 그리고 어업자)가 어업관리목표 어종 및 비관리목표 어종과 어종의 생태, 그리고 환경을 포함한 어업자원의 직접 사용 가치와 비사용 가치(즉, 내재 가치)등에 관련된 제문제를 다루는 것을 그 내용으로 한다. 따라서, 이 논문은 국제사회에서 지속적 발전과 관련된 지식의 현 주소와 어업관리에 없어서 갖는 함축적 의미와 주로 관계된다. 이 논문은 지속적 발전에 대한 개념의 기원과 형성과정, 개념 구조를 상세히 고찰함으로써 어업의 지속적 발전을 위한 어업관리정책 수립을 위한 방향설정에 기여하게 될 것이다. 또 이 논문에서는 지속적 발전의 개념하에서 어업의 지속성과 지속적 발전이 어업관리에 어떠한 의미를 갖는지 고찰한다. 그 하나로 이 논문에서는 FAO에서 최근에 제시한 해양어업의 지속적 발전지표를 어떻게 설정하는지에 대한 가이드라인을 분석 고찰하였다. 이 FAO의 지속적발전지표는 지속적 발전의 평가체계의 구성요소와 어업에 대한 지속적 평가체계[sustainable development reference system(SDRS)]를 수립하는데 있어서 필요한 관련 절차에 관해 특별한 의미를 부여해 줄 것으로 생각한다. 마지막으로 본 논문에서는 SDRS가 지역어업 협력체계 구축에 있어서 어떠한 역할을 할 것인가를 강조함으로써 결론을 내리고 있다.

쿼터제에 기초한 중국연근해 어업관리에 대한 제도적 연구

모영통(Yong Tong Mu),최정윤(Jeong Yoon Choe) 한국수산경영학회 2001 수산경영론집 Vol.32 No.2

이 논문은 2002년도 부경대학교 수산경영학과 박사학위논문(A Study on Institutional Arrangements for Quota-Based Management : The Case of China`s Marine Capture Fisheries)의 일부이다. 이 논문의 기본목적은 쿼터제에 기초한 중국의 어업관리를 위한 제도적인 틀을 세우고자 하는데 있으며, 이런 목적을 달성하기에 위해 이 논문은 다음과 같이 구성하여 연구를 진행시켰다. 제1장은 연구목적과 문제의 제기에 이어 제2장에서는 중국 해양어업의 개발과 이에 따른 문제점을 분석하였으며, 여기에서 쿼터제에 기초한 어업관리정책의 제도적 제안을 함과 동시에, 제3장에서는 중국 해양어업의 현실과 중국 사회의 일반적인 현상을 분석하여 제4장을 통해 쿼터제에 기초한 중국의 어업관리를 위한 제도적 프레임워크를 제안하였다. 마지막으로 본 논문을 요약하고 향후 계속되어야 할 연구과제를 제시하였다. 본 논문의 중요한 연구 결과는 다음과 같다. 현재 중국 수산업의 관리체제는 질적 규제 중심 관리제도, 그리고 정부 주도하의 어업관리 과정으로 특징지을 수 있다. 이러한 명령과 통제 (command-and-control) 방식의 전통적인 중국어업 관리제도로서는 어업인들에게 있어서 자원 보존에 대한 동기와 제도에 대한 수용성을 약화시키며, 정부 규제를 오히려 무시하게 되는 결과를 초래한다. 결과적으로 현행 중국의 어업관리제도는 어업인에게 있어서 자원 보전에 대한 유인을 약화시키고 단기적인 수익을 극대화하도록 유도하는 맹점을 지니므로 인해 더 이상 지속적인 어업성립의 보장을 할 수 없다는 점을 지적할 수 있다. 중국정부는 이러한 어업관리제도의 불완전성을 인식하여 2000년 10월 31일에 1986년에 제정된 수산업법을 개정하게 되었으며, 새로운 중국의 수산업법은 어업 허가제도와 함께 할당량제에 기초한 어업관리제도를 국가가 운영하는 것으로 특징지울 수 있다. 그러나 아직까지 중국은 할당제에 근거한 어업관리제도를 미실시중에 있으며, 그 내용도 애매모호한 점을 많이 가지고 있다. 또한 중국의 절대적 어획량은 현재 논란의 여지로 남아있고, 거대 어업 인구의 근본적인 요구와 중국 어선의 국제적인 경쟁력, 그리고 유어(遊漁)에 대한 사회적 요구 등도 중국의 수산정책이 채결해야 할 과제이다. 위에서 고찰한 내용을 기초로 하여 우리는 중국의 쿼터제에 기초한 어업관리에 대해 다음과 같은 몇 가지를 제안한다. 중국 연근해어업에 있어서 할당제 모형에 참가하는 어업 참여자들의 유형은 세 가지로 구분할 수 있다. 첫째는 어촌에 거주하면서 생존수단으로 소규모 어업에 종사하는 경우이고, 둘째는 유어어업의 경우이며, 셋째는 상업적 목적으로 어업에 종사하는 집단으로 나눌 수 있다. 이러한 세 집단을 하나의 제도의 틀로 통합하기 위해서는 국가의 총허용 어획량(TAC)을 총 어촌 허용어획량(TAFVCs)과 총 허용 유어 어획량(TARCs) 및 총허용 상업적 어획량 (TACCs)의 세 부문으로 나눌 것을 제안한다. 그리하여 다시 TAFVCs와 TARCs, 그리고 TACCs는 어촌별 어획량(IFVQs), 개별 유어 회사별 어획량(IRCQs), 그리고 양도 가능한 개별 상업적 어획량(ITCQs)으로 나누어 관리하도록 한다. 이와 같이 중국의 국가 총허용어획량(TAC)을 IFVQs와 IRCQS, 그리고 ITQCQs의 세부문으로 구분하여 할당하고, 여기에 기초하여 어업을 관리하는 것은 중국에 있어서 사회적 형평성과 경제적 효율성과의 상충관계를 고려하여 고안된 것으로, 중국에 있어서 수산업을 통한 경제적 및 사회적 효과를 동시에 기대할 수 있을 것이다.

Recently, microturbines have received attention as a small-scale distributed power generator. Since the exhaust gas carries all of the heat release, the microturbine CHP (combined heat and power) system is relatively compact and easy to maintain. Generating hot water or steam is usual method of heat recovery from the microturbine. In this work, a heat recovery unit producing hot water has been attached at the end of a 30㎾ class microturbine and its performance characteristics following microturbine power variation was investigated. Heat recovery performance has been compared for different operating conditions such as constant hot water temperature and constant water flow rate. Variations of performance parameters of the heat recovery unit such as flow rates, temperatures and effectiveness were analyzed. Total CHP efficiency was also provided.

A Calculation for the Viscosity of Fluids by Using Van Der Waals Equation of State

Jhon, Mu Shik,Chair, Tong Seek,Pak, Hyung Suk,Kim, Won Soo 한국화학공학회 1989 NICE Vol.7 No.3

A new equation for the viscosity of fluid is presented by considering that the viscosity is equal to the product of the shear pressure and the shear relaxation time. The shear pressure and the shear relaxation time are calculated thermodynamically by applying the van der Waals model for fluids. The calculated viscosities for various simple substances are in good agreements with those of the observed values through liquid-critical point-gas region.

Recently, microturbines have received attention as a small-scale distributed power generator. Since the exhaust gas carries all of the heat release, generating hot water is usual method of heat recovery from microturbine CHP (combined heat and power) systems. The power of microturbines decreases as ambient temperature increases. This study predicted micoturbine power boost by injecting hot water generated by heat recovery. Influence of injecting water at two different locations was examined. Water injection improves power, but efficiency depends much on the injection location. Injecting water at the compressor discharge shows a much higher efficiency than the combustor injection. However, the combustor injection may have as much available cogeneration heat as the dry operation, while the available heat in the compressor discharge injection is much smaller than the dry operation.
