  • The study was done to improve the job training course for Community Health Practioners (CHPs) by evaluating the level of help that the training provided to the CHPs in carrying out their work and to analyze the management activities of the CHPs in order to develop a more effective CHP training program. The methodologies used in the study were a questionnaire survey. The survey results were analyzed using SPSS Windows. The study results are as follows. 1. The total average level of help from the job training(Theory. Practice and Field Practice) for carrying out the CHP work was found to be $3.04\pm.53$ (of a possible 4), which indicates a high level of help. The average for clinical practices was $3.16\pm.60$. for theory. $3.11\pm.40$ and for field practice. $2.84\pm.60$. 2. For the theory content of the job training courses. the help level was low in the area of mother and child health management/family planning with an average of $2.65\pm.62$ and in the area of health information system development with an average of $2.62\pm.83$. The reason for these deficiencies were. in order of frequency. few opportunities to apply learning. training content that was inadequate. training methodologies which were incongruent with content. improper training items and insufficient class hours. For the practice. the clinical work in rehabilitation/orthopedics departments and in ENT/Opthalmology departments had averages of $2.96\pm.86$ and $2.97\pm.80$ respectively. This low level resulted from the lack of direct experience. lack of sincerity during the practice time. lack of practice guidance. insufficient time and lack of practice equipment. in that order. For the field practice. the delivery management averaged $2.06\pm.90$ as the lowest help level. In this case 68% of respondents replied that there were no relevant reasons for this deficiency. 21% responsed that there was a lack of direct experience, 7%, a lack of practice guidance and 4.8%, insufficient time. 3. There were significant differences for several demographic variables when comparing the help level of the clinical courses (practice and Field Practice). A higher help level was reported by older nurses as compared to younger ones, experienced nurses as compared to scholarship nurses, and married over single. Also for nurses who had finished more other programs and were qualified or licensed in several areas the level was high. Although it was not statistically significant the level was higher if the work area was in a rural county, not a city, and if one had more recently completed the job training(P<,05). 4. Of the respondents 58.6% replies stated the period of job training for the CHP was adequate, but 51.7% reported that the period for theory courses was too short while an other 48.3% responded that it was sufficient. For practice locations, 50% responsed that it was good to practice in medical institutions(primary, secondary and tertiary) at the same time. While 48.3% agreed that doing theory and practice simultaneously was good, and 56.9% agreed that field practice should be done after completing theory and practice training. Hence, the development of new field practice guidelines suitable for changing environments of health management are required in place of the existing ones which were considered low in help level to the practical work of the CHPs.

  • This paper addresses the development of inverse compensation techniques for a class of ferromagnetic transducers including magnetostrictive actuators. In this work, hysteresis is modeled through the domain wall theory originally proposed by Jiles and Atherton[1]. This model is based on the quantification of the energy required to translate domain walls pinned at inclusions in the material with the magnetization at a given field level specified through the solution of an ordinary differential equation. A complementary differential equation is then employed to compute the inverse which can be used to compensate for hysteresis and nonlinear dynamics in control design.

  • Even though there are lots of learning theory and learning Instruments today, it is still difficult to teach the children individually taking their learning ability into consideration. In this case lower level children may be discouraged and cannot catch up the next course. The purpose of this paper is to design and develop webb-based courseware on arithmetics for the disabled children and apply the program to the class field. This program is very useful for the left-behind children because it enables the repetitive and visible learning.

  • Functoriality conjecture is one of the central and influential subjects of the present day mathematics. Functoriality is the profound lifting problem formulated by Robert Langlands in the late 1960s in order to establish nonabelian class field theory. In this expository article, I describe the Langlands-Shahidi method, the local and global Langlands conjectures and the converse theorems which are powerful tools for the establishment of functoriality of some important cases, and survey the interesting results related to functoriality conjecture.

  • Scale scores for cognitive domains have been used as an important indicator for both academic achievement and clinical diagnosis. For example, in education, Cognitive Abilities Test (CogAT) has been used to measure student's capability in academic learning. In a clinical setting, Cognitive Impairment Screening Test utilizes items measuring cognitive ability as a dementia screening test. We demonstrated a procedure of generating cognitive ability test items similar as in CogAT but the theory associated with the generation is totally different. When creating cognitive test items, we applied automatic item generation (AIG) that reduces errors in predictions of cognitive ability but attains higher reliability. We selected two cognitive ability test items, categorized as a time estimation item for measuring quantitative reasoning and a paper-folding item for measuring visualization. As CogAT has widely used as a cognitive measurement test, developing an AIG-based cognitive test items will greatly contribute to education field. Since CLASS is the only LMS including AIG technology, we used it for the AIG software to construct item models. The purpose of this study is to demonstrate the item generation process using AIG implemented within CLASS, along with proving quantitative and qualitative strengths of AIG. In result, we confirmed that more than 10,000 items could be made by a single item model in the quantitative aspect and the validity of items could be assured by the procedure based on ECD and AE in the qualitative aspect. This reliable item generation process based on item models would be the key of developing accurate cognitive measurement tests.

  • The control of underactuated mechanical system is very complex for the loss of its control inputs. The model of underactuated mechanical systems in a potential field is built with Lagrangian method and its structural properties are analyzed in detail. A genetic algorithm (GA)based stable control approach is proposed for the class of under actuated mechanical systems. The Lyapunov stability theory and system properties are utilized to guarantee the system stability to its equilibrium. The real-valued GA is used to adjust the controller parameters to improve the system performance. This approach is applied to the underactuated double-pendulum-type overhead crane and the simulation results illustrate the complex system dynamics and the validity of the proposed control algorithm.

  • e-revolution makes a lot of changes in the methodology all over the world. That is, the theory of real time showing helps people to access audio and visual wherever and whenever they are. In the pst computers were considered as only tools which could make us work easily. However, the meaning of computer is changing with e-revolution nowadays. Computers are not just computers as they were; they have done a lot of things which we thought impossible and they will do in the future as well. This new wave encourages people who are teaching the design to use computers whatever they do. For example, instead of using pencil and a drafting board, most people in the design field work with monitors, mouse and plotter. Therefore, most people who are in the design field need to have the ability of computer skills. They have to use computers not only in their class but also in their office. However, if we use computers for visual presenting in the class, it will not be enough to catch the e-revolution. That is, we should work with computers in the creative and conceptual design such as the using of the design information and the applying digital techniques in the early stage of the work. The purpose of this study is to show how to work with computers in the spacial design process especially th using of the DIS(Design Information System) and the applying digital techniques in the early stage of the work.

  • 본 연구는 코로나19 사태 이후 증가한 비대면 수업의 효과성을 측정하기 위해 대학 수업에서 강조되고 있는 핵심역량과 학습 만족도를 사용하여 알아보고자 하였다. 이를 위해 충북 청주에 있는 S 대학교에서 진행되는 의류학 이론 전공 1개 교과목에서 플립러닝(flipped learning)이 적용된 비대면 수업을 진행하고 해당 교과목에 설정된 주요 핵심역량인 문제해결 역량을 중심으로 3가지 세부 영역인 문제분석력, 자원·정보·기술활용 능력, 융·복합적 사고력 및 전반적인 학습 만족도에서 비대면 수업 사전-사후 차이를 검증하였다. 연구결과 학생들은 플립러닝이 적용된 비대면 수업에 참여한 후, 3가지 문제해결 역량 세부 영역에서 능력이 향상되었다고 인식하고 있었으며 전반적인 학습 만족도도 증가한 것으로 나타났다. 기존에 의류학 전공 분야에서 비대면 수업에 대한 효과 측정은 주로 패션디자인과 의복 구성 교과목에서 수행되었지만, 본 연구결과를 토대로 이론 중심의 강의식 수업에서 플립러닝과 같은 교수·학습법이 적용된 비대면 수업 진행은 학습자의 전공 지식 습득을 넘어 문제해결 역량과 같은 대학생 핵심역량의 향상에도 효과적인 방법이라 제언할 수 있다. 본 연구는 의류학 전공 교과목 중 이론 중심의 수업에 학습자 중심의 비대면 수업 방식의 적용 사례와 그 효과를 제시하였다는 데 의의가 있으며 대학생 핵심역량 향상을 위한 차별화된 비대면 수업 설계 전략에 기초자료가 되리라 생각한다.

  • In this investigation, the aerodynamic performance evaluation of a 1MW class blade has been performed with the purpose of the verification of target output and its clear understanding of flow field using CFD commercial code, ANSYS FLUENT. Before making progress of CFD analysis the HERACLES V2.0 software based on blade element momentum theory was applied for confirmation of quick and approximate performance in the preliminary stage. The blade was designed to produce the target output of a 1MW class at a rated wind speed of 12m/s, which consists of five different airfoils such as FFA W-301, DU91-W250, DU93-W-210, NACA 63418 and NACA 63415 from hub to tip. The mechanical power by CFD is approximately 1.195MW, which is converted into the electrical power of 1.075MW if the system loss is considered to be 0.877.
