  • 농업과 IT기술 융합이 가속화됨에 따라 식물공장 내 작물의 품질 및 생산성을 향상시키기 위한 연구가 활발히 진행 중이다. 식물공장의 생산성을 최대화하기 위해서는 먼저 시설 내부의 특성을 고려하여 생육에 적합한 열 환경과 공기의 흐름을 제공하기 위한 고도의 생장환경 관리기술이 필요하다. 현재 운영되고 있는 식물공장은 특화된 공기유동장치의 설계 및 운영기술이 확립되지 않아 온도 기류 편차로 인한 불균일한 품질의 작물 생산, 재배기간 연장에 따른 에너지 소비 등의 문제점을 내포하고 있다. 이를 해결하기 위해서는 식물공장 시설의 설계 단계에서 전산유체역학 시뮬레이션을 이용한 공기유동장치의 배치 및 운영기술에 대한 최적화 과정이 선행되어야 한다. 본 연구에서는 CFD(Computational Fluid Dynamics) 시뮬레이션을 이용한 순환 팬의 적정 배치 및 유속을 파악하여 식물공장 시설 내부의 각 지점별 온도 편차를 최소화하고 에너지소비를 절감한다. 시뮬레이션 조건은 순환 팬의 설치 위치 및 수량 그리고 유속변화에 따라 총 12가지의 Case로 구분하였으며 해석을 위한 경계 조건 변수는 동일하게 설정하였다. 시뮬레이션 결과, 2set의 순환 팬을 식물재배기 상단에 부착한 Case D의 제어 조건이 설정온도에 부합하는 296.33K의 평균온도를 유지하면서 식물생육에 적합한 0.51m/s의 기류분포를 보였다. 또한, 순환 팬의 유속을 변화시킨 결과, 출구 유속을 2.09/s로 설정한 Case D-3이 에너지 효율 측면에서 가장 우수한 결과를 보였다.

  • This study was undertaken to meet more fully the demands for improved training of library personnel, occasioned by the rapidly changing roles and functions of libraries as they try to adapt to the vast social, economic and technological changes currently in progress in the Korean society. The specific purpose of this research is to develop a standard curriculum at the batchelor's level that will properly equip the professional personnel in Korean libraries for the changes confronting them. This study started with the premise that to establish a sound base for curriculum development, it was necessary first to determine what concepts, knowledge, and techniques are required for professional library personnel to perform it at an optimal level of efficiency. Explicitly, it was felt that for the development of useful curricula and courses at the batchelor's level, a prime source of knowledge should be functional behaviours that are necessary in the job situation. To determine specifically what these terminal performance behaviours should be so that learning experience provided could be rooted in reality, the decision was reached to use a systems approach to curriculum development, which is an attempt to break the mold of traditional concepts and to approach interaction from an open, innovative, and product-oriented perspective. This study was designed to: (1) identify what knowledge and techniques are required for professional library personnel to perform the job activities in which they are actually engaged, (2) to evaluate the educational needs of the knowledge and techniques that the professional librarian respondents indicate, and (3) to categorise the knowledge and techniques into teaching subjects to present the teaching subjects by their educational importance. The main data-gathering instrument for the study, a questionnaire containing 254 items, was sent to a randomly selected sample of library school graduates working in libraries and related institutions in Korea. Eighty-three librarians completed and returned the questionnaire. After analysing the returned questionnaire, the following conclusions have been reached: (A) To develop a rational curriculum rooted in the real situation of the Korean libraries, compulsory subjects should be properly chosen from those which were ranked highest in importance by the respondents. Characters and educational policies of, and other teaching subjects offered by, the individual educational institution to which a given library school belongs should also be taken into account in determining compulsory subjects. (B) It is traditionally assumed that education in librarianship should be more concerned with theoretical foundations on which any solution can be developed than with professional needs with particulars and techniques as they are used in existing library environments. However, the respondents gave the former a surprisingly lower rating. The traditional assumption must be reviewed. (C) It is universally accepted in developing library school curricula that compulsory subjects are concerned with the area of knowledge students generally need to learn and optional subjects are concerned with the area to be needed to only those who need it. Now that there is no such clear demarcation line provided in librarianship, it may be a realistic approach to designate subjects in the area rated high by the respondents as compulsory and to designate those in the area rated low as optional. (D) Optional subjects that were ranked considerably higher in importance by the respondents should be given more credits than others, and those ranked lower might be given less credits or offered infrequently or combined. (E) A standard list of compulsory and optional subjects with weekly teaching hours for a Korean library school is presented in the fourth chapter of this report.

  • 본 연구에서는 서울에 위치한 G 영재원의 과학영재학생들을 위하여 제공된 영재교육 프로그램에 대한 학생들의 인식을 조사하였다. 이 프로그램은 Betts와 Kercher(1999)에 의해 제안된 자율학습자 모형을 기반으로 설계된 통합적인 프로그램이라는 점에서 독특하다. 프로그램의 효과를 알아보고자 영재원의 교육목표들이 내재된 항목들에서 긍정적 영향이 있었는지 묻는 설문을 제작하여 프로그램에 참여한 중학교 1학년부터 중학교 3학년까지의 학생들을 대상으로 실시하였다. 설문 결과 거의 모든 학생들이 긍정적 영향에 강한 동의를 나타냈다. 학생들은 유용하고 흥미로운 과학 내용물을 배웠고, 소그룹 내에서 동료들과 함께 협력하는 의미 있는 경험을 즐겼으며, 탐구과제에 의해 많은 도전을 받았다고 응답하였다. 학생들은 또한 스스로 학습하는 방법을 익히게 되었고, 또한 자신들의 선택과 결정이 존중되었다는 사실이 동료와의 의견 조율이나 능동적인 탐색 등에 긍정적인 영향을 미쳤다고 했다. 이는 자율학습자 모형이 성공적으로 구현되고 있으며 학생들이 자율학습자로써 성장하고 있음을 시사한다. 프로그램에 처음 참여한 학생보다 참여한 기간이 길었던 학생들이 좀 더 긍정적인 반응을 보였으며, 이것은 시간이 지나면서 프로그램의 일관성으로 인한 축적된 효과를 기대할 수 있음을 시사한다. 또한 세부 프로그램들, 특히 ALM 수업, 분과 수업, 학술대회가 과학적 탐구의 과정과 자율학습자 특성에 기여하는 비중이 비슷하여, 과학적 탐구과정과 자율학습자 교육을 위한 전략이 프로그램 전체에 내재하고 있으며 서로 유기적으로 긍정적 상호작용을 하여 시너지 효과를 내는 통합적 접근이 이루어지고 있는 것으로 판단된다. 본 연구의 결과는 영재들을 위한 특정 교육 모델에 기초한 프로그램의 일관성이 영재학생들을 위한 더 나은 교육환경을 제공할 수 있다는 점을 제안한다.

  • One of the latest fields of research in the area of output devices is tactual display devices [13,31]. These tactual or haptic devices allow the user to receive haptic feedback output from a variety of sources. This allows the user to actually feel virtual objects and manipulate them by touch. This is an emerging technology and will be instrumental in enhancing the realism of wearable augmented environments for certain applications. Tactual displays have previously been used for scientific visualization in virtual environments by chemists and engineers to improve perception and understanding of force fields and of world models populated with the impenetrable. In addition to tactual displays, the use of wearable audio displays that allow sound to be spatialized are being developed. With wearable computers, designers will soon be able to pair spatialized sound to virtual representations of objects when appropriate to make the wearable computer experience even more realistic to the user. Furthermore, as the number and complexity of wearable computing applications continues to grow, there will be increasing needs for systems that are faster, lighter, and have higher resolution displays. Better networking technology will also need to be developed to allow all users of wearable computers to have high bandwidth connections for real time information gathering and collaboration. In addition to the technology advances that make users need to wear computers in everyday life, there is also the desire to have users want to wear their computers. In order to do this, wearable computing needs to be unobtrusive and socially acceptable. By making wearables smaller and lighter, or actually embedding them in clothing, users can conceal them easily and wear them comfortably. The military is currently working on the development of the Personal Information Carrier (PIC) or digital dog tag. The PIC is a small electronic storage device containing medical information about the wearer. While old military dog tags contained only 5 lines of information, the digital tags may contain volumes of multi-media information including medical history, X-rays, and cardiograms. Using hand held devices in the field, medics would be able to call this information up in real time for better treatment. A fully functional transmittable device is still years off, but this technology once developed in the military, could be adapted tp civilian users and provide ant information, medical or otherwise, in a portable, not obstructive, and fashionable way. Another future device that could increase safety and well being of its users is the nose on-a-chip developed by the Oak Ridge National Lab in Tennessee. This tiny digital silicon chip about the size of a dime, is capable of 'smelling' natural gas leaks in stoves, heaters, and other appliances. It can also detect dangerous levels of carbon monoxide. This device can also be configured to notify the fire department when a leak is detected. This nose chip should be commercially available within 2 years, and is inexpensive, requires low power, and is very sensitive. Along with gas detection capabilities, this device may someday also be configured to detect smoke and other harmful gases. By embedding this chip into workers uniforms, name tags, etc., this could be a lifesaving computational accessory. In addition to the future safety technology soon to be available as accessories are devices that are for entertainment and security. The LCI computer group is developing a Smartpen, that electronically verifies a user's signature. With the increase in credit card use and the rise in forgeries, is the need for commercial industries to constantly verify signatures. This Smartpen writes like a normal pen but uses sensors to detect the motion of the pen as the user signs their name to authenticate the signature. This computational accessory should be available in 1999, and would bring increased peace of mind to consumers and vendors alike. In the entertainment domain, Panasonic is creating the first portable hand-held DVD player. This device weight less than 3 pounds and has a screen about 6' across. The color LCD has the same 16:9 aspect ratio of a cinema screen and supports a high resolution of 280,000 pixels and stereo sound. The player can play standard DVD movies and has a hour battery life for mobile use. To summarize, in this paper we presented concepts related to the design and use of wearable computers with extensions to smart spaces. For some time, researchers in telerobotics have used computer graphics to enhance remote scenes. Recent advances in augmented reality displays make it possible to enhance the user's local environment with 'information'. As shown in this paper, there are many application areas for this technology such as medicine, manufacturing, training, and recreation. Wearable computers allow a much closer association of information with the user. By embedding sensors in the wearable to allow it to see what the user sees, hear what the user hears, sense the user's physical state, and analyze what the user is typing, an intelligent agent may be able to analyze what the user is doing and try to predict the resources he will need next or in the near future. Using this information, the agent may download files, reserve communications bandwidth, post reminders, or automatically send updates to colleagues to help facilitate the user's daily interactions. This intelligent wearable computer would be able to act as a personal assistant, who is always around, knows the user's personal preferences and tastes, and tries to streamline interactions with the rest of the world.

  • In this paper, I consider the development of methods in contemporary human geography in terms of a dialectical relation of action and structure, and try to draw a new horizon of method toward which geographical research and spatial theory would develop. The positivist geography which was dominent during 1960s has been faced both with serious internal reflections and strong external criticisms in the 1970s. The internal reflections that pointed out its ignorance of spatial behavior of decision-makers and its simplication of complex spatial relations have developed behavioural geography and systems-theoretical approach. Yet this kinds of alternatives have still standed on the positivist, geography, even though they have seemed to be more real and complicate than the previous one, The external criticisms that have argued against the positivist method as phenomenalism and instrumentalism suggest some alternatives: humanistic geography which emphasizes intention and action of human subject and meaning-understanding, and structuralist geography which stresses on social structure as a totality which would produce spatial phenomena, and a theoretical formulation. Human geography today can be characterized by a strain and conflict between these methods, and hence rezuires a synthetic integration between them. Philosophy and social theory in general are in the same in which theories of action and structural analysis have been complementary or conflict with each other. Human geography has fallen into a further problematic with the introduction of a method based on so-called political ecnomy. This method has been suggested not merely as analternative to the positivist geography, but also as a theoretical foundation for critical analysis of space. The political economy of space with has analyzed the capitalist space and tried to theorize its transformation may be seen either as following humanistic(or Hegelian) Marxism, such as represented in Lefebvre's work, or as following structuralist Marxism, such as developed in Castelles's or Harvey's work. The spatial theory following humanistic Marxism has argued for a dialectic relation between 'the spatial' and 'the social', and given more attention to practicing human agents than to explaining social structures. on the contray, that based on structuralist Marxism has argued for social structures producing spatial phenomena, and focused on theorising the totality of structures, Even though these two perspectives tend more recently to be convergent in a way that structuralist-Marxist. geographers relate the domain of economic and political structures with that of action in their studies of urban culture and experience under capitalism, the political ecnomy of space needs an integrated method with which one can overcome difficulties of orthhodox Marxism. Some novel works in philosophy and social theory have been developed since the end of 1970s which have oriented towards an integrated method relating a series of concepts of action and structure, and reconstructing historical materialism. They include Giddens's theory of structuration, foucault's geneological analysis of power-knowledge, and Habermas's theory of communicative action. Ther are, of course, some fundamental differences between these works. Giddens develops a theory which relates explicitly the domain of action and that of structure in terms of what he calls the 'duality of structure', and wants to bring time-space relations into the core of social theory. Foucault writes a history in which strategically intentional but nonsubjective power relations have emerged and operated by virtue of multiple forms of constrainst wihthin specific spaces, while refusing to elaborate any theory which would underlie a political rationalization. Habermas analyzes how the Western rationalization of ecnomic and political systems has colonized the lifeworld in which we communicate each other, and wants to formulate a new normative foundation for critical theory of society which highlights communicatie reason (without any consideration of spatial concepts). On the basis of the above consideration, this paper draws a new norizon of method in human geography and spatial theory, some essential ideas of which can be summarized as follows: (1) the concept of space especially in terms of its relation to sociery. Space is not an ontological entity whch is independent of society and has its own laws of constitution and transformation, but it can be produced and reproduced only by virtue of its relation to society. Yet space is not merlely a material product of society, but also a place and medium in and through which socety can be maintained or transformed.(2) the constitution of space in terms of the relation between action and structure. Spatial actors who are always knowledgeable under conditions of socio-spatial structure produce and reproduce their context of action, that is, structure; and spatial structures as results of human action enable as well as constrain it. Spatial actions can be distinguished between instrumental-strategicaction oriented to success and communicative action oriented to understanding, which (re)produce respectively two different spheres of spatial structure in different ways: the material structure of economic and political systems-space in an unknowledged and unitended way, and the symbolic structure of social and cultural life-space in an acknowledged and intended way. (3) the capitalist space in terms of its rationalization. The ideal development of space would balance the rationalizations of system space and life-space in a way that system space providers material conditions for the maintainance of the life-space, and the life-space for its further development. But the development of capitalist space in reality is paradoxical and hence crisis-ridden. The economic and poltical system-space, propelled with the steering media like money, and power, has outstriped the significance of communicative action, and colonized the life-space. That is, we no longer live in a space mediated communicative action, but one created for and by money and power. But no matter how seriously our everyday life-space has been monetalrized and bureaucratised, here lies nevertheless the practical potential which would rehabilitate the meaning of space, the meaning of our life on the Earth.

  • 본 연구는 과학관 설계와 운영을 위해서는 관람객의 관점을 고려해야 하지만 아직까지 그러한 점이 충분하지 않다는 주장에 근거하였다. 이에 본 연구에서는 학생들이 과학관에 대해 어떤 이미지를 가지고 있는지, 그리고 어떠한 전시물을 원하는지를 조사하였다. 조사에 참여한 학생은 영재교육원 중학생 31명과 과학고 학생 177명이었고, 설문지를 이용해 조사하였다. 연구결과, 과학관에 방문한 경험이 있는 학생은 51%에 불과하였으나, 한번 과학관에 방문했던 학생들의 평균 방문횟수는 4.2회로 나타나, 일단 과학관에 방문하고 나면 반복적으로 방문하는 경향이 있음을 알 수 있었다. 과학관에 대한 좋았던 이미지를 조사한 결과, 학생들은 과학관에서 체험과 실험을 했던 것과 다양하고 새로운 전시물, 재미있고 신기하고 흥미로운 전시물 등의 순서로 나타났다. 나빴던 이미지로는, 전시물 자체에 대해서 새로움/흥미부족, 정보/안내 부족, 내용부족, 체험부족의 순으로 구분할 수 있었고, 전시물 외적 요소로는 환경, 관리미비, 운영부족 구성의 불편함의 순으로 구분할 수 있었다. 과학관에 바라는 점을 조사한 결과는, 체험/실험/활동, 다양한/새로움, 재미/흥미 순으로, 전시물 외적 요소에는 관리, 구성, 안내/정보, 환경, 운영 순으로 나타났다. 그리고 과학관 방문횟수가 적을 학생일수록 과학관에서의 외적인 준비를 더 필요로 한다는 것을 알 수 있었다. 이상의 결과를 바탕으로, 제한적이지만, 학생의 관점에서 본 좋은 과학관을 위한 방향을 제안하였다. 학생들에게 국립광주과학관의 4개 대범주를 주고, 각 큰 주제별로 배우고 싶거나 알고 싶은 구체적인 주제를 조사한 결과, 학생들은 1인당 평균 4.0개를 응답하였고, 하나의 주제에 대해서는 평균 2.9개의 응답이 중복되어 나타났다. 주제별로는 '생활 속 과학' 주제, '해양, 우주, 미래의 과학' 주제, '빛과 과학' 주제, 그리고 '문화와 예술과 과학' 주제 순으로 나타났다. 그리고 학생들이 알고 싶고 배우고 싶다고 언급한 주제들은 국내 4개 국립과학관별로는 9.2~19.7%, 전체 평균으로는 36.9%만이 전시되어 있음을 알 수 있었다. 이러한 연구방법과 결과는 과학관의 평가뿐 아니라, 앞으로 과학관 설립이나 특별기획을 위한 계획에서 어떤 전시물을 선정할 것인지에 대한 결정에 도움을 줄 수 있다고 본다.

  • This study is search for analyzed the primary factor of psychological characters of crippled person toward psychological rehabilitation that is the most foundmental to all rehabilitation for a crippled person. The research is, make a comparative analyze to personality character, value character, and motion, and then examined the relation of among then, by applies to high school's crippled students. First. in the personality character aspect, a group of crippled student's is shown that the factor of family relations is lack harmony than normal group, that is, shown up that a parents and family members is oversensitiveness to crippled person, So sometimes they overprotectiveness, unconcered, and not accept it is. Also, in the factor of confrontability aspect, a group of crippled person's average is shown to high as compared with normal group, and then, it shown that they are irresponsible, have a weak self-control, and show a marked trend toward self-control. This is means that crippled person have scruples about psychological and social adaptation. But friendship, adaptability, cheefulness. and emotonal stability is shown no difference with normal person. Accordingly, in the personality aspect, the falter of family-relation and confrontability can be know that the object of psychological rehabilitation. Second, in the sence of value aspect, crippled students is show that the average score had higher than normal group toward the factor of variety, therefor we can know that they have purpose to more pursur of variety in the living. This is consideration that a raise from the limited of social contact chance and badly informed and experience. Also, the factor of purpose-intention is shown that crippled students had low non than normal group, then, that means that they have a weak will toward cope with various problems in daily living. Crippled student is, in contrast to lacked fixed purpose with self-living, and also insufficient tring to accomplish their objects. Third, crippled students motion shown that related to low level of personality character and a sence of value factor. Daily living activity is show that related to the factors of confrontability and cheerfulness. This means that rehabilitation service given a change to confrontability and cheerfulness that can be effect is related. And the activity of home is related with confrontability, psychological rehabilitation for the change of activity is can say that it should be contribute to strengthen toward responsibility and self-control from self-central to intention at rho others. Fourth, the relation between an motion and a value of crippled student is shown low level of regulations that can be ignore. In sum, in the rehabilitation of crippled person, hereafter, a study subject is if which search to character factor and to find out effect inter-factors within the the factor of psychological rehabilitation as medical, occupational, social rehabilitation, then probably more effective development toward rehabilitation programs. Conseguently, hereafter for the crippled person's rehabilitaton, the study should be rquirement for establish a character and factors each filed of rehabilitation. The study sibject toward crippled person's rehabilitation for the fature is search for character factor toward medical. occupational, and social rehabilitation. and find out inter-relation among then like as search of this study for psychological rehabilitation. For the rehabilitation of crippled person, if is not preceding of study like this, it ought to be difficult to creation service as well as development to effective program.

  • 해양계대학교 실습해기사들은 승선하기 전 필요한 안전교육을 충분히 이수하고 승선해야 되지만 기초안전교육만 이수하고 승선을 하며 승선실습을 마치고 졸업 전까지 남은 학기 중 상급안전 교육과 탱커선 교육을 이수하고 있다. 그러나 해양대학교 실습해기사들은 선박회사 승선실습 과정 중에 위험에 노출되는 많은 작업들을 하게 된다. 이처럼 대부분의 상선들은 ISM관리 하에서 선박회사 및 승선하는 선박에서 각종 점검표에 의해 사전 교육을 행하고 작업을 하는 것이 당연한 것이다. 그러나 본 연구조사 결과 선박회사와 승선하는 선박 및 해양대학교에서도 교육이 제대로 이루어지지 않고 있으며 특히 '유해화학 물질의 취급'은 승선 경험이 없는 실습해기사들에게 상당한 위험이 되고 있다. 또한 승선실습 해기사들은 유해화학물질 취급에 관한 개인안전과 취급에 관한 사전교육이 없이 승선하게 되는 경우가 대부분이다. 이로 인해 실습해기사들이 승선실습 중 유해화학물질 취급 부주의와 무지로 인해 신체적 손상을 입고 하선을 하거나 승선에 어려움에 처하는 경우가 종종 발생하고 있다. 따라서 사고를 미연에 방지하기 위해서는 승선 실습 전에 해양대학교에서 이 부분의 철저한 교육이 이루어져야 하고, 선박회사에서는 취급하는 유해화학물질의 안전에 대한 데이터 베이스화가 체계적으로 갖추어져야하며, 각 선박에 맞는 유해화학물질 안전교육을 위한 온라인 켄텐츠 개발이 절실히 필요하다. 또한, 선박회사에서는 유해화학물질 안전점검일지를 만들어 관리감독하고, 선박에서는 이에 관한 교육을 이수한 관리책임자를 지정하여 안전교육과 관리를 하여야 할 것을 제안한다.

  • 목 적: 한의사의 유방암 보완치료에 대한 실태를 조사하고 임상진료지침의 필요성을 알아보고자 본 연구를 시행하였습니다. 방 법: 본 연구는 e mail 설문지를 사용하였으며 유방암 환자 치료 여부, 내원환자들의 병기, 증상, 진단, 치료, 기타 의견 등을 설문하였습니다. 결 과: 322명이 응답하였으며 그 중 84명이 해당 기관에서 유방암 치료를 시행하고 있었습니다. 내원 환자들의 주된 호소는 피로 및 전신 소력감이었고 변증 및 맥진을 주된 진단법으로 한약 및 침뜸을 중심으로 치료하고 있다고 응답하였습니다. 유방암의 한의학적 보완치료로서 임상진료지침이 필요하다고 생각하며 개발된다면 적극적으로 사용하겠다고 응답하였습니다. 결 론: 유방암 보완치료 실태조사를 통해 임상진료지침에 대한 필요성을 알 수 있었으며 추가적인 연구가 필요합니다.
