The purpose of this study was to understand the present condition about the space planning of the nursing rooms at the child care center in U.S.A. The researchers investigated the physical conditions of the centers through sketching, measurement, taking pictures and observation. On the other hand, to understand the user's needs, the interview to the directors of the centers was performed. As a result, the followings were proposed. The grouping of children depending upon the age has to be more classified according to the development period. And the guideline for the space areas has to be improved to a larger standard than present regulation. And the most impressive characteristic of the center in U.S.A. is the functional space design. The space such as toilet, washing room, kitchenet are well organized into the nursing rooms for children. Various ideas for arranging above functions in the small nursing rooms have to be developed in Korea. And the dynamic space arrangement of nursing room is also impressive. The material of the floor has to be considered variously for the comfort of the children.

디지털 음악 컨텐츠의 활용이 보편화되고 음악 데이터의 양이 방대해지면서 데이터베이스로부터 음악 컨텐츠를 효과적으로 질의하고 검색하는 기능이 절실해졌다. 본 논문에서는 사용자들이 자주 질의하는 멜로디 부분을 이용하여 음악 검색을 보다 빠르고 효과적으로 수행할 수 있는 음악 검색 시스템인 FMF(Fast Melody Finder)를 제안한다. 이 기법은 어떤 음악에 대해 사용자가 기억하고 질의하는 내용이 대개 음악의 특정 선율에 한정되어 있다는 사실에 기반하고 있으며, 사용자의 이러한 질의 패턴을 이용하여 자주 질의되는 부분을 인덱스로 사용함으로써 사용자가 원하는 곡을 빠르게 찾아낼 수 있게 해준다. 또한 이러한 선율들을 다루기 위해서, 사용자의 허밍에 의한 음향 질의와 오선지를 통한 질의로부터 추출된 음높이와 음의 길이를 분석하여 UDR과 LSR 스트링으로 변환함으로써 더욱 정확한 질의를 할 수 있다. 프로토타입 시스템을 구현하고 다양한 실험을 통하여 논문에서 제안하는 기법의 우수성을 보인다.

As the population of the aged and the disabled increases, the needs for universal design is also growing. Universal design is to design for diverse users including all ages from children to the elderly, the disabled and non-disabled, the pregnant, the tourist, and etc. This study is intended to develop the design evaluation tool and guidelines of universal design for applying to space design. In order to achieve this, four basic spaces in human living such as residential space, educational space, working space, and cultural space were selected. Then, the elements of universal design were chosen for each space. The numbers of areas in each space were 12 for residential spae, 5 for educational space, 6 for working space, and 6 for cultural space. Also, 60 elements of universal design for residential space, 53 for educational space, 36 for working space, and 46 for cultural space were selected. The field observation with photos and user evaluation survey were carried out for each space by using these elements. Finally, the elements and guidelines of universal design applied for spatial design were suggested. This consisted of 8 areas and 67 elements. This would be useful for designing space for all people.

Recently, manufacturing work has been transformed to small scale production form with various types to act up to user's expectation from mass production with a little items required in the past. Then FMS using NC type machinaries has been applied actively also in domestic manufacturing line to meet thus tendency, but there are many machining troubles occured during work process not be settled yet. Nowdays high efficiently has been required no less than high precision in grinding work for the improvement of productivity. In this study, to represent more advance FMS can be adapted to thus situation In-process type monitoring method using AE and Current sensors is suggested to investigate the machining condition in grinding process. As results form this experimental study, it is recognized well that grinding conditions and dressing point of in time cab be estimated effectively using monitoring method suggested. Furthermore, surface shape of grinding wheel on voluntary point of in time can be predicted indirectly through the observation and comparison of AE signal waveform obtained as performance of continuous dressing work.

디지털 오디오 컨텐츠의 활용이 보편화되면서 오디오 데이타베이스에 대해 컨텐츠를 효과적으로 질의하고 검색하는 기능이 절실해졌다. 본 논문에서는 사용자들이 자주 질의하는 멜로디 부분을 이용하여 오디오 검색을 효과적으로 수행할 수 있는 새로운 인덱스 기법을 제안한다. 이 기법은 어떤 오디오에 대해 사용자가 기억하고 질의하는 내용이 대개 오디오의 특정 부분에 한정되어 있다는 사실에 기반하고 있다. 사용자의 이러한 질의 패턴을 이용하여 자주 질의되는 부분을 감지하고 인덱스로 사용함으로써 사용자가 원하는 곡을 빠르게 찾아낼 수 있게 해준다. 이러한 방법은 데이타베이스의 모든 컨텐츠를 순차적으로 검색하는 기존의 방법에 비해 적은 비용으로 검색 속도를 크게 향상시키며 특히 기존의 검색 시스템 상위 모듈로 사용이 가능하다. 프로토타입 시스템을 구현하고 다양한 실험을 통하여 논문에서 제안하는 기법의 우수성을 보인다.

본 논문은 단락의 자동 구분을 통해 중요한 문장을 추출하는 요약 시스템을 제안한다. 먼저 어휘의 재출현 여부를 파악하여 어휘의 일치도와 어휘의 역할 변화와 같은 재출현 어휘의 양상 정보를 수집하고, 이를 통하여 문장 간의 긴밀도를 정량적으로 계산한다. 다음으로 측정된 문장간 긴밀도를 이용하여 사용자의 추출 범위에 따라 단락을 구분하고, 각 단락의 대표 문장을 선정하여 최종 요약문을 추출한다. 제안한 방법은 문서 제목, 문장의 위치, 수사 구조 등의 정보를 이용하지 않기 때문에 수사 구조가 자주 발견되지 않는 문서에도 적용이 가능하다.

이 논문에서는 opencv와 android studio를 이용하여 시각장애인이 앞에 사물이 있는지 유무를 구분해준다. 스마트폰의 카메라와 연결하여 차영상으로 움직임을 감지하면 해당 부분을 Labeling 작업을 수행하고 mean shift알고리즘을 이용하여 계속 tracking하는 작업을 수행하여 시각 장애인에게 물체가 앞에 있다는 것을 알려주는 방식의 어플리케이션을 제작하고 있다. 실시간 움직임 관측을 위하여 OpenCV 기반의 C++ 프로그램을 사용하였으며, 어플리케이션은 android studio에서 제작할 예정이다. 연구 결과 Labeling으로 움직이는 물체들을 판별하였으며, Mean-Shift 알고리즘으로 박스영역을 지정하여 물체가 움직이면 박스도 함께 이동하여 실시간으로 사물을 Tracking작업을 수행한다.

The purposes of this study are to analyze the problems of the elderly using kitchens by ergonomic work evaluation methods, and to make suggestions for planning and remodeling of the kitchens for the elderly. The work evaluation methods which used in this study were direct-observing methods, which contained the process of 2 or 3 times each visiting to four different houses where elderly people live. For direct-observing methods, analyzing with movement observations and observation methods with photos and videos were used. Characteristics of subject elderly people and problems of their kitchens were analyzed by static measurements, interviews, pictures, and videos. The data, which are recorded movements of the preparing meal of the elderly were analyzed by playing it back repeatedly. As results, physical characteristics of the elderly was the most important consideration; a participant with the arthritical knee was limping at the kitchen entrance due to the difference of the floor level, and a user with a bent back was working on the floor or place an elbow on the worktable to support her body. Those results made a conclusion about the common problems of the kitchens, and suggested the check list which has to be considered when designing the elderly using kitchen.

The purpose of this study is to understand the physical accessibility of the child care centers for disabled children in Japan. Fifteen centers located in Tokyo, Japan were surveyed through sketching, measuring, taking pictures, and observation. To understand the user's needs. the directors of the centers were interviewed. As a result,the followings suggestions were proposed. First, when the entrance of the center is close to the road, careful design for the entrance area is required to secure the safety of children using wheelchairs. If possible, a fence or door between the corridor and entrance is necessary. Second, most aspects of accessibility are pretty well designed. But a canopy over the entrance area is required to escape the rain. Third, a wider corridor space is desirable for storing and driving wheelchairs and for special equipment for the disabled. Forth, because the emergency exits were installed but not used, the new and safer emergency exits should be installed. These results will be a good case reference for developing Korean design guidelines for the children with disabilities.

The article describes actions and strategies to obtain higher productivity on maritime automobile terminals. The main focus is on elaboration of efficient and effective organizational structure to model and implement short-term, mid-term and long-term strategies. In addition, with an empiric approach we combined the analyses of current findings in important scientific papers and our acknowledgments in practical research of north Adriatic maritime automobile terminals. The main goal is to propose actions towards increasing system's productivity. Based on our research of the north Adriatic maritime automobile terminals and with Lambert's model an in-deep analysis of limiting factors, user's expectations and possibilities for productivity increase has been performed. Moreover, with our acknowledgments a three-level decision-support model is presented. With an adequate model implementation it is possible to efficiently develop and implement different strategies of productivity measurement and productivity increase, especially in the fields of internal transport productivity, entrance/exit truck gates operations and wagon manipulations. According to our observation a significant increase might be achieved in all three fields.
