According to the development of information technology, there are many services in our life. These services make our life safe and convenient. However, the increment of the services also causes the increment of human concern and effort to control these services. The context-aware service is the service that provided their functionality at the right time and to the right place by analysis user's current situation. The most previous studies about context-aware service regard that context-aware services are defined by the developer who has expertise in information technology. The definition of the context-aware services by the developer makes difficult to reflect user's personal preferences and life pattern to the services. In this paper, we propose an user interface EUCAS(by End-User, Context-Aware Service development) that make the user can define and manage their own context-aware service according to their preferences. We expect EUCAS can be effective user interface technology for providing personalized context-aware service.

In this paper, we propose sensibility recognition model that recognize user's sensibility using brain waves. Method to acquire quantitative data of brain waves including priority living body data or sensitivity data to recognize user's sensitivity need and pattern recognition techniques to examine closely present user's sensitivity state through next acquired brain waves becomes problem that is important. In this paper, we used pattern recognition techniques to use Multi Layer Perceptron (MLP) that is pattern recognition techniques that recognize user's sensibility state through brain waves. We measures several subject's emotion brain waves in specification space for an experiment of sensibility recognition model's which propose in this paper and we made a emotion DB by the meaning data that made of concentration or stability by the brain waves measured. The model recognizes new user's sensibility by the user's brain waves after study by sensibility recognition model which propose in this paper to emotion DB. Finally, we estimates the performance of sensibility recognition model which used brain waves as that measure the change of recognition rate by the number of subjects and a number of hidden nodes.

오늘날 분산 컴퓨팅 환경에서 운용되는 시스템이 증가됨에 따라 시스템의 관리작업은 고수준의 자동화를 요구하고 있다. 이에 따라 시스템 관리방식은 전통적인 관리자 중심에서 시스템 스스로가 자신의 문제를 인식하고 상황을 분석하여 해결하는 자율 컴퓨팅 방식으로 변화하고 있으며, 현재 이에 대한 연구가 많은 연구기관에서 다양한 방법으로 이루어 지고 있다. 그러나 이러한 대부분의 연구에서 자율 컴퓨팅의 한 요소인 자가 치유는 문제가 발생한 이후의 치유에 주로 초점이 맞추어져 있다. 이러한 문제를 해결하기 위해서는 시스템 스스로가 동작환경을 인식하고 에러의 발생을 예측하기 위한 예측 모델을 필요로 하게 된다. 따라서, 본 논문에서는 자율 컴퓨팅환경에서 자가 치유를 지원하는 4 가지 예측 모델 설계 방법을 제안하며, 본 예측 모델을 ID3 알고리즘, 퍼지추론, 퍼지뉴럴네트워크 그리고 베이지안 네트워크가 각 시스템 상황에 맞추어 적절하게 사용되는 하이브리드 방식이며, 이를 통해 보다 정확하고, 신속한 에러 예측이 가능해진다. 우리는 제안 모델을 평가하기 위해 본 예측 모델을 자가 치유 시스템에 적용하여 기존 연구와 예측 효율을 비교하였으며, 그 결과를 통해 제안 모델의 유효성을 증명하였다.

This study purposes to analyze the changes of the pain care awareness and health related quality of life of the people with the chronic low back pain through the participation in the kinesio-taping self application education program. A total of 30 people with chronic LBP participated and they divided into experimental(n=15) and control group(n=15). An experimental group participated in the Kinesio-taping education program for 4 weeks and a control group was treated by a therapist. Through these, the pain care awareness and health related quality of life were analyzed. In the care of the health care awareness, the canadian Occupational Performance Measure was used to assess the subjects' performance and satisfaction. The short form-8 health survey was used to the health related quality of life. The results of the health care awareness and health related quality of life were increased in the experimental group and the statistically significant difference showed between group. This education program is a meaningful method to improve the health related quality of life from the pain care in the daily life by itself. Thus, the kinesio-taping self application education program should be considered for the people with the chronic low back pain.

The importance of personalized services has been attracted in smart home environments according to the development of ubiquitous computering. In this paper, we proposed the smart home personalized service system based on context information using the speech recognition. The proposed service consists of an OSGi framework based service mobile manager, service manager, voice recognition manager, and location manager. Also, this study defines the smart home space and configures the commands of units, sensor information, and user information that are largely used in the defined space as context information. In particular, this service identifies users who exist in the same space that shows a difficulty in the identification using RFID through the training model and pattern matching in voice recognition and supports the personalized service of smart home applications. In the results of the experiment, it was verified that the OSGi based automated and personalized service can be achieved through verifying users in the same space.

In this paper, we propose an efficient multi-object recognition and tracking scheme based on interest points of objects and their feature descriptors. To do that, we first define a set of object types of interest and collect their sample images. For sample images, we detect interest points and construct their feature descriptors using SURF. Next, we perform a statistical analysis of the local features to select representative points among them. Intuitively, the representative points of an object are the interest points that best characterize the object. in addition, we make the movement vectors of the interest points based on matching between their SURF descriptors and track the object using these vectors. Since our scheme treats all the objects independently, it can recognize and track multiple objects simultaneously. Through the experiments, we show that our proposed scheme can achieve reasonable performance.

With the advent of the Fourth Industrial Revolution, there is an increasing demand for interdisciplinary studies in the realm of university education. Accordingly, this study sought to explore learners' perceived expectation factors for a modular curriculum, one of the primary strategies for curriculum revision in interdisciplinary departments, by applying the Expectation Theory. Learners' perceptions were measured pre and post during the second semester of 2022. The results confirmed that among the expectation factors, the selection factor significantly decreased after the course compared to before. Changes in the understanding and perceived difficulty level of tool utilization within the course may have influenced these results. The significance of this study lies in providing direction for curriculum revisions in interdisciplinary departments by analyzing learners' perceptions of the modular curriculum. Specifically, curriculum design should focus on reducing difficulties and cognitive burdens associated with educational tool utilization. Furthermore, considering that students' prior experience and understanding of educational tools can impact educational outcomes, it is crucial to factor these elements when designing a modular curriculum.

This study investigated the students' perceptions of environmental scientists and their work and the factors influencing the students' images of them by using the Draw-An-Environmental-Scientist-Test (DAEST). The DAEST was administered to 413 students in 10th and 11th grades selected from three high schools in Seoul. The results revealed that the students' images of environmental scientists were different from the stereotypical images of scientists. In the students' drawings, it was difficult to distinguish the gender and age of environmental scientists. Most students also perceived environmental scientists collecting data on environmental pollution by using experimental equipments and a laptop computer in the field. The students answered that the factors affecting their images of environmental scientists were mass media, school education, internet, and so on. According to the students' grade and gender, there were differences in the perceptions of environmental scientists and their work, and there were factors that influenced their images. Educational implications of these findings are discussed.
