김은경 한국기술교육대학교 1998 論文集 Vol.5 No.1

In order to overcome the problems with first generation expert systems at the symbol level, recently various knowledge level development techniques of second generation expert systems have been proposed. But, these techniques are conceptual modelling techniques. This paper modifies and complement these conceptual modelling techniques and proposes a Task Modelling (TM) technique as a practical knowledge level expert system development technique. This paper defines a Task as a knowledge unit consisted of a goal, execution conditions, behaviour knowledge, and so on. And, this paper defines a Task Diagram to depict structural, dynamic, and functional aspects of task easily. This paper also defines Inference Types as basic units to describe behaviour knowledge of tasks. Also, this paper proposes task processing algorithm based on the state of tasks and implements a task debugger.

Background: clinical indicators are objective measures of process or outcome of patient care in quantitative terms. This study aims to review the medical records of patients who 'return to operating room during the same admission', which is one of the critical clinical outcomes, and describe the result by unplanned reoperation rate. Methods: Computerized patient registry was used for selecting subject conditions. For medical records retrieved, two nurse evaluators identified the presence of explicit reoperation planning in medical records. Results: Overall reoperation rate was 2.8% and unplanned reoperation rate 1.3%, The main category of reoperation cause was the postoperative bleeding. Duration of stay from previous operation to reoperation of the unplanned group, 12.7 days, was shorter than that of the planned(p<.05). The differences did not reach statistical significance in age, sex and length of stay. Conclusion: Results suggested that unplanned reoperation rate was lower than 'threshold' level other institutions had established. However, this result could become comparable only after management of medical records would be improved and risk adjusted.

에이전트 기반의 맞춤형 교육 시스템

김은경,허선영 한국기술교육대학교 2006 論文集 Vol.12 No.1

According to the rapid popularization of the internet, recently the number of web-based remote education systems are rapidly increased. And demand for the customized educational service suitable for individual learner's level and learning pattern is increasing. Meanwhile, most remote education systems do not provide adequately customized educational service fit for each learner's level and lots of learners easily lose their interest in studying. Therefore, many researchers have used agents to provide personalized educational service by analyzing learner's level and learning pattern automatically. In this paper, we designed and implemented an agent-based customized education system(ACE) for individual learning. ACE tries to provide more suitable and individually customized learning contents by dividing learners' level into 5 stages and reproduces new learning contents on section unit instead of chapter unit. Also, ACE encourages learners' participation by providing proper feedback and sending e-mails including each learner's studying stage and learning target regularly.

본 연구는 중학생들의 특기ㆍ적성 교육 활동 실태를 파악하고 여가만족과의 관계를 규명함으로써 여가 선용 및 특기ㆍ적성 교육 효과를 극대화 시킬 수 있는 방안을 제시하기 위한 기초 자료를 제공하고자 하였다. 본 연구에서 얻어진 결과는 다음과 같다. 1. 사회인구학적 변인에 따라 특기ㆍ적성 교육 활동 참여 실태는 여학생이 남학생보다 참여율이 높았고, 읍, 면 지역 중학생들은 모두가 참여한 반면에 광역시 중학생은 절반 정도만이 참여하였으며 시 지역에서는 거의 대부분이 참여하지 않는 것으로 나타났다. 가족의 소득이 높은 집단이 특기ㆍ적성 교육활동에 대한 참여율이 낮았으며, 부모의 학력이 높은 집단도 특기ㆍ적성 교육 활동 참여는 낮았다. 2. 사회인구학적변인에 따른 여가만족의 차이를 보면 심리적, 교육적, 사회적, 휴식적, 생리적, 환경적 만족의 6개 하위영역 중에서 읍, 면 지역 거주학생들이 광역시나 시 지역 학생들보다 높게 나타났다. 학년별로는 1학년 학생이 교육적 만족, 환경적 만족이 높았고, 가족의 소득이 높고 아버지의 학력이 높은 집단에서 여가만족이 더 높은 것으로 나타났다. 3. 특기ㆍ적성 교육 활동 참여 동기에 따른 여가만족은 참여 동기가 자신의 적성에 맞거나 진학을 위해서라고 하는 자발적인 의사결정의 결정에 높게 나타냈다. 참여 기간에 따라 참여 기간이 4개월 미만인 경우 높은 만족을 나타냈고, 집중도에 따른 여가만족에서는 모든 영역에서 집중도가 높은 집단의 여가만족이 높게 나타났다. The study has examined the relationship between the middle school students' after school activities and leisure satisfaction to provide the opportunity of making good use of leisure time and of developing students' latent talent and aptitude. The research finding are as follows : 1. Based on socio-demographic variables, the female students had more rates of participation in talent and aptitude educational activity than male students. The number of the students from rural areas was much bigger than that of cities such as Gwangju or other big cities in Chonnam. But the students whose parents made a lot of money showed less interest in participating talent and aptitude educational activities. 2. Based on the research of socio-demographic variables, students from counties or smaller areas showed more satisfaction than Gwangju in leisure satisfaction among the six subordinate categories. 7th graders were more satisfied in educational and environmental leisure activities than 8th or 9th graders. Moreover, as the family income is higher and as the father's educational level is higher, satisfaction rate from leisure activities cam out to be higher. 3. In regard to satisfaction they get from their leisure activities, it was comparatively high when they had the activities voluntarily as their hobbies or for fun. Some students regarded it as their chances for the next step and they were really satisfied, too. And also the period of time was one of the factors that affected students satisfaction. They were satisfied enough when they had the activities less than four month in a year. The students who had strong concentration and great enthusiasm showed high leisure satisfaction in all areas except for the environmental one.

조정에 관한 연구를 위한 실험 환경 설계

김은경 한국기술교육대학교 2003 論文集 Vol.10 No.1

In building Intelligent Agent Societies(IASs), it is important to design and implement coordination in accordance with the known requirements and anticipated working conditions of the IAS in question. Coordination has been defined as the process of managing dependencies between activities in an IAS. Unfortunately, currently there is little theoretical support that could help in this process. Therefore, our final goal is to generate a empirically-based theory of coordination. In order to get basic data for constructing a theory of coordination, firstly we need to develop an experimental environment to conduct rigorously designed experiments in which control variables operated under well-defined conditions and performance measures were observed. In this paper, we outline our approach to design the experimental environment, that is based on the Unified Modeling Language(UML).

Ontologies are formal theories that are suitable for implementing the semantic web. Which is a new technology that attempts to achieve effective retrieval, integration, and reuse of web resources. Ontologies provide a way of sharing and reusing the knowledge among the people and the heterogeneous application systems. The role of ontologies is that of making explicit specified conceptualizations. In this context, domain and generic ontologies can be shared, reused, and integrated in the analysis and design stage of information and knowledge systems. This study aims to design an ontology for juju lodges and tour, and build an Internet web retrieval system based on the proposed ontologies. This study found that we can take the same result for synonym that cilent use.

This paper shows that the identified and unidentified components of surface roughness in NC turning lathe which can not be analyzed in time domain such as Rmax, Ra can be isolated in frequency domain by FFT analyzer. By interfacing FFT analyzer with stylus surface roughness instrument, surface roughness on change of working condition, especially tool feed, such as 0.1, 0.15, 0.2, 0.25, 0.3(mm/rev) can be analyzed in frequency domain as follows. 1. By frequency analysis of surface roughness profile, the basic wave length of surface roughness can be obtained to isolate the identified and unidentified components of surface roughness. 2. With increase of tool feed, the unidentified components of surface roughness increase. 3. Since Rmax, which can be obtained by stylus surface roughness is proportion to the output voltage of FFT analyzer, FFT analyzer also can be used to measure surface roughness in time domain such Ra, Rmax.

To develope a sauce using Gochujang which can give foreigners good overall acceptance such as good flavor, taste, color, viscosity and versatility to many foods, we studied on the rheological properties and color control, recipes with spices, herbs, syrup, salt and flavor ingredients and sensory evaluation by Chinese, American and Japanese including Korean. From the survey, the Americans suggested that the proper fellow food of Gochujang sauce be fried chicken, barbecue, hamburger and pizza, and hoped to reflect red color, low viscosity, hot taste, low sweetness, salty and sourness and diet effect. The Chinese suggested pork and fried food as a fellow food with Gochujang sauce and showed similar opinion in the sensory attributes like the Americans except sweetness. When 5% of starch and xanthan gum was added to sauce, respectively, the yield stress of Gochujang sauce showed 33.21 Pa similar to tomato ketchup. In fluidity measured by voistic flow meter, Gochujang sauce showed 6.2 cm/30sec more or less faster than tomato ketchup which showed 4.7 cm/30sec. Gochujang sauce tended to show strong red color and lightness as pH decreased. The pH adjustant and Paprica oleoresin(2%) improved a value to 12.11 and L value to 24.24 similar to tomato kechup(a:12.42, L:25.48). The 1st gochujang sauce product showed 4.50 to 5.75 points in the overall acceptance in the consumer test including foreigners and koreans. However, the 2nd Gochujang sauce product showed 5.90 points and 6.30 points in the pizza and fried chicken, respectively, in the same consumer test. Therefore, we propose that Gochujang can be used for developing sauce products which is most acceptable for various foreigners.
