Background: The purpose of this study was to develop a sit-to-stand transfer assistive device, and to conduct a feasibility test. Design: A technical note. Methods and results: In this study, we developed a sit-to-stand transfer assistive device for the elderly and the disabled who have difficulty standing up independently from sitting positions. The sit-to-stand transfer assistive device allows the user to transfer the weight from a sitting position to a standing position while shifting the weight forward by grabbing and pulling a support stand. Ten healthy adults participated in the feasibility test of the device. Each participant used the developed sit-to-stand transfer assistive device and investigated supplementation through a brief interview. As a result of the feasibility test, the opinion was that the device could assist the sit-to-stand transfer to some extent. There were opinions that it needed a function to adjust the height of the knee protective plate in the sitting position according to the user's physical characteristics. Because of the inconvenience of operating the lock device for fixing the position and adjusting inclination, there was an opinion that the improvement for a locking device is needed. There were opinions that it would be better to reduce the size of the device due to its inconvenience of portability. Conclusion: In this study, we developed the sit-to-stand transfer assistive device for the elderly and the disabled who have difficulty standing up independently from sitting positions. In addition, it is considered that the upgrade of the device is necessary for the future since there are supplementary opinions on some points.

The 21st centurt, the era of change-space, is requesting us to readjust our education system. In other words, we should renew it by looking back into the past cultivate more advanced ideas. As a matter of fact junior colleges have been considered just as miniture of universities in every way such as curriculum, prossor emploment, school affairs, etc. Therefore we should change our existing education system not to be criticized for the next century. May students are trained for industry as dental technicians in our department of college. We should educate experiment and practice substantially as college professors as well as exert ourselves in developing our abilities to adapt to high diverse industrial technique, putting emphasis on practice more than theory. It is mecessary for us to sufficiently teach the technique to good students and make them display their abilities in order to produce high quality goods. Reinvestment ineducation is a condition precedent. Dental laboratories have just employed the students that graduated from our college. However it's time for a change. They should pay attention to our education and assist us in all respects with the thought of equally educating professional dental technicians together with us. The field practice system is subject to reinforcement so that our students have more opporunities of utilizing the tools and materials for practice. Finally we should not only carry out new reserch more deeply no less than dental technicians who are experienced in business for development of education system but endeavor to meet pratical education by adding what is pratically needed in dental laboratories to the existing education system.

This study examines the fashion illustrations textbooks that have been published in the domestic market, and identifies its characteristics and problems in regards to its use in developing creative students. The purpose of the study is to propose ways to improve the development of the fashion illustration textbooks. The research method of this study are as follows: First, the teaching materials on fashion illustration in Korea were researched to examine the current state of publication. Second, its contents were analyzed to identify its characteristics. Third, an improvement plan of educational materials on fashion illustration in Korea were proposed. As for the scope of study, 18 volumes of fashion illustration teaching materials published in Korea during 2004-2014 were targeted. It should be noted that translated publications, digital fashion illustration materials and teaching materials for specialized and professional organizations were excluded. Conclusions of this study are as follows: First, examination of the textbooks revealed that additional content is needed regarding theoretical understanding of fashion illustration, as well as illustrations of men and children, as there was an insufficient amount of those topics. Second, the contents on the illustration application using current trends were lacking in the unit on illustration application. Accordingly, it is necessary to develop contents that reflect these trends. Lastly, the textbooks should be packaged with compact discs CDs containing video clips to assist students to get a better grasp of the material. The result of this study can be used to develop new teaching materials on fashion illustration, and be utilized as basic information in the curriculum design of fashion illustration.

Home care, known also as domiciliary care, is part of the community care service that is a responsibility of the local government authorities in the UK as well as many other countries around the world. The aim is to provide the care and support needed to assist people, particularly older people, people with physical or learning disabilities and people who need assistance due to illness to live as independently as possible in their own homes. It is performed primarily by care workers visiting clients' homes where they provide help with daily activities. This paper is concerned with the dispatching of care workers to clients in an efficient manner. The optimized routine for each care worker determines a schedule to achieve the minimum total cost (in terms of distance traveled) without violating the capacity and time window constraints. A collaborative population-based meta-heuristic called Particle Swarm Optimization (PSO) is applied to solve the problem. A particle is defined as a multi-dimensional point in space which represents the corresponding schedule for care workers and their clients. Each dimension of a particle represents a care activity and the corresponding, allocated care worker. The continuous position value of each dimension determines the care worker to be assigned and also the assignment priority. A heuristic assignment scheme is specially designed to transform the continuous position value to the discrete job schedule. This job schedule represents the potential feasible solution to the problem. The Earliest Start Time Priority with Minimum Distance Assignment (ESTPMDA) technique is developed for generating an initial solution which guides the search direction of the particle. Local improvement procedures (LIP), insertion and swap, are embedded in the PSO algorithm in order to further improve the quality of the solution. The proposed methodology is implemented, tested, and compared with existing solutions for some 'real' problem instances.

Boreholes that are drilled in soft or unconsolidated materials such as gravels and coals are prone to collapse. To maintain the hole, some kinds of casing pipes are needed. If thereby a plastic pipe e.g. PVC is used for the casing, Televiewer tool is still capable of detecting structural features such as fractures in the borehole wall behind the pipe, whereas other borehole-imaging logging devices such as BIPS (Borehole Image Processing System) and FMS(Formation Micro Scanner) won't provide any information about that. Televiewer's primary component is a piezoelectric transducer centered in the hole. It acts as both a transmitter and receiver, and sends an ultrasonic beam. That is reflected, in the same manner as the seismic wave propagation, from the both sides(inner and outer surfaces) of the casing pipe, transmits through the pipe and then reflected from the borehole wall. With an appropriate choice of time-windowing, it is possible to capture the returning signals from both the borehole wall and the outer side of casing pipe as well. A suite of laboratory tests were performed on various physical models composed of plastic pipes with different diameters. Although the amplitudes of returning signals were reduced to about half the usual value due to the transmission loss, the dynamic range of Televiewer tool was sufficient to observe the structural features behind the casing pipe. Besides, several representative case studies at various research areas in our country are presented. The results demonstrate the usefulness of the transmissivity of Televiewer acoustic km, which will assist in further structural interpretation.

온라인 교육시장이 확대됨에 따라 다양한 교육용 콘텐츠들이 출시되어지고 이를 사용하는 사용자들의 사용성과 사용자환경이 반영될 수 있는 콘텐츠 개발 방법이 연구되고 있다. 시장의 양적 확대를 뒷받침할 콘텐츠의 질적 성장을 위해서는 새로이 개발되지는 콘텐츠의 개발 방향성 확보 시점에서 기존 출시 모형에 대한 빠른 분석이 매우 중요하다. 하지만 콘텐츠 개발과정에서 개발 목표 설정에 필요한 전형적 모델의 추출과정을 직관적으로 협의할 수 있는 툴의 부재로 제작시안을 기준으로 한 반복적 업무 회귀가 개발공정에 필요한 많은 인력과 시간을 낭비하게 한다. 통계를 이용한 자료원 검증툴은 개발 전 과정과 최종 개발 결과에 영향을 주는 프로토타입의 선정 시 협력 업무를 수행하는 단일기업 내 또는 다수의 기업 간 소통의 부재로 인한 성과 이원화 문제를 공정 간에 스크린해주는 긍정적 효익으로 작용할 수 있다. 본 연구는 시료가 충분치 않은 AR기반 교육용 콘텐츠의 개발과정에 적용할 후속 현장실험 적용 통계서비스모델을 설계하는 것으로써 유사 범주의 시료 확보를 통해 개발에 필요한 데이터를 확보하는 것이 적정하여 빅데이터를 이용한 자료의 취합과 의사결정이 프로세스를 기준으로 진행되었다. 이번 연구에서 제시되는 데이터 통계분석서비스 기본 모형은 직관적인 다차원 요인과 속성의 선택과 검출이 가능한 구조로 설계하였으며 후속 현장형 실험연구와 연계하여 조직 내 또는 다수 기업 간 협력활동에 조력이 가능한 온라인 기반 데이터 통계분석서비스로 제안하고자 한다.

본 연구에서는 학교정보공시를 활용하여 과학중점 고등학교에서의 SW동아리 활동 실태를 분석하였다. 전국의 103개 과학중점 고등학교를 대상으로 SW동아리에 영향을 주는 요인을 분석하였으며, 학교교육계획서, 학교특색사업계획서, 과학중점학교 운영보고서를 통해 SW동아리 활동 실태를 분석하였다. 동아리 참여율에 가장 많은 영향을 미치는 것은 정보교과의 편성이므로 교육과정 개편이 가장 시급한 것으로 판단된다. 또한 SW관련 비교과활동 및 예산지원은 정(+)적 영향을 미치고 있었고, 고등학교가 소재한 지역의 사회 경제적 배경을 반영하기 위해 사용한 학비지원율은 부(-)적 영향을 미치고 있었다. 그러나 고등학교의 전반적인 학력 수준을 파악하기 위한 학업성취도는 유의한 영향을 미치지 않았다. 따라서 가능한 많은 학생들이 SW관련 비교과활동을 할 수 있도록 지원하되, 이를 위해서는 지역 및 학교의 특성을 반영한 프로그램 개발 및 예산지원이 필요할 것으로 판단된다.

Background: Traumatic rupture of the aorta is a life-threatening injury that must be diagnosed as rapidly as possible and treated immediately. The chest X-ray is a valuable tool for screening traumatic rupture of the aorta in blunt chest trauma. And various chest radiologic parameters are being used as diagnostic tools for aortic injury. The purpose of this study is to identify chest radiographic parameters that may assist in the detection of traumatic rupture of the aorta and to compare these findings with those of other reports. Methods: This study involved 30 adult patients with traumatic rupture of the aorta seen at the emergency department of the Asan Medical Center from 1997 to 2004. The control subjects were 30 healthy patients with neither lung nor cardiovascular disease. We retrospectively assessed over 14 parameters on chest X-rays. Results: In 11 of the 14 parameters, there were significant differences between the study group and the control group. There was no significant difference in the M/C ratio (mediastinumto-chest width ratio) between the two groups, and neither the left nor the right paraspinal interface was statistically significant (p value>0.05). Our study indicates that new criteria for the MC ratio and for the paraspinal interfaces are needed for screening traumatic aorta injury. The other radiographic parameters for traumatic rupture of the aorta need to be further assessed through a prospective study.

As we increase installing computers, traditional commerce by paper document is replaced by Electronic Commerce, paperless document commerce. Electronic Commerce proves to be an intermediary for increasing efficiency on work, which makes us use it more. This study aims to contribute to streamline local export by analyzing trade firms and manufacturers' using status of Electronic Commerce on work in Pusan. I sent questionnaires to 202 firms working on trade in Pusan to do survey. The sample of this study consists of 96 of them. I analyze using status of Electronic Commerce on work based on those data. The result shows that the more the firms install facility to be able for Electronic Commerce and the better they understand Electronic Commerce related laws, the more they select that on work. Generally The firms in Pusan rarely select Electronic Commerce on work and even acknowledges how much that is needed on work. Considering all of them, this study shows the method of streamlining local export by Electronic Commerce as follows; First, all kinds of Electronic Commerce such as trade related site in Internet should be systemized. Second, the laws on Electronic Commerce should be established in details. Third, workers on firms should be educated on Electronic Commerce. Forth, the firms should install the facility for Electronic Commerce, assist financially and make marketing strategy for selecting Electronic Commerce on each step in work. In conclusion, export in Pusan would be streamlined when the use of Electronic Commerce, effective intermediary, is motivated and we take that method to use on work properly.
