The purpose of this study was to analyze task performance and importance level of the dietitian who is working in the public health nutrition area. Work oriented job analysis methodology was employed for the study purpose. Subjects of 38 dietitians currently working at health centers in 2002 were recruited. Based on the focus group interview with 7 public health nutritionists and 7 professors, information about task elements was collected. Questionnaires measuring work performance and self-perception of importance of the selected task elements were administered. The results of this study can be summarized as follows; 1) The tasks with high performance and importance level among 20 tasks are developing nutrition education material (B1), nutrition services for adults and the elderly (C3), writing the proposal for nutrition services (A2), evaluating service effect (A4), improving professionalism (E1), and self management (E2). 2) The task elements with high performance and importance level among weekly task elements are nutrition education for diabetes (C56), nutrition counseling for adults (C47), nutrition for hypertension (C53), managing and keeping records (C80), nutrition education for kindergarten and nursery school children (C42), searching for nutrition education materials (B26), and searching for media (B27). 3) The number of task elements with high performance and importance level among monthly task elements are 13 in the planning and evaluation of public health nutrition service, and 5 in developing nutrition education materials. The tasks of a dietitian in the public health center show a very wide spectrum. However dietitians recognize most of the tasks are important even though they cannot perform those tasks adequately.

본 연구의 목적은 구글 클래스룸(GC)을 기반으로 문제중심학습(PBL)의 평가를 조사하는 것입니다. GC는 쉽고 자유로운 온라인 학습으로 최근 교육과 훈련에 중요한 역할을 하고 있다. 학생들은 아이디어와 자원을 공유하고, 도메인 전체에 걸쳐 지식을 적극적으로 전달하고 PBL의 주어진 문제에 대한 해결책을 연구하면서 점점 더 자기 주도적인 학습에 독립적이 된다. 학생들은 과제 페이지에서 제출일을 확인하고 클릭 한 번으로 과제를 시작할 수 있고 선생님은 과제 완료 여부를 빠르게 확인할 수 있으며 GC에서 점수를 바로 매길 수 있다. 본 연구에서는 GC를 기반으로 한 PBL의 평가를 설계하였다. 학생들은 주어진 자료를 읽고 과목의 목적을 파악하여 학습 문제를 조사한다. 그 후에 그들은 주제를 토론하고 보고서를 작성하여 연구 논문, 책, 인터넷 자료를 가지고 그것들을 공부한다. 연구 결과는 GC에 기반을 둔 PBL이 함께 학습하는 데 효과적이라는 것을 보여 주었다. 학생들은 PBL학습 환경에서 긍정적인 태도를 보였다. 이 연구는 GC에서 PBL평가의 개발이 가능하다는 것을 제안한다.

An efficient measurement and evaluation system for hand tool tasks will provide a practical solution to the problem of designing and evaluating manual tool tasks in the workplace. Few studies on the biomechanical analysis of hand postures and tool handling tasks exist because of the lack of appropriate measurement techniques for hand force. A measurement system for the finger forces and joint angles for analysis of manual tool handling tasks was developed in this study. The measurement system consists of a force sensing glove made from twelve Force Sensitive Resistors and an angle-measuring glove (Cyberglove$\^$TM/, Virtual technologies) with eighteen joint angle sensors. A biomechanical model of the hand using the data from the measurement system was also developed. Systems of computerized procedures were implemented integrating the hand posture measurement system, biomechanical analysis system, and the task analysis system for manual tool handling tasks. The measurement system was useful in providing the hand force data needed for an existing task analysis system used in CTD risk evaluation. It is expected that the hand posture measurement developed in this study will provide an, efficient and cost-effective solution to task analysis of manual tool handling tasks. These tasks are becoming increasingly important areas of occupational health and safety of the country.

In developing the HMI(Human-Machine Interface) evaluation system for the IVNS(In-Vehicle Navigation System), design guidelines and evaluation methods are the most crucial problems for its use and efficiency. As the part of this system, focused on the final product of the database, subjective mental workload assessment is seriously considered to evaluate the driver's own driving task using the IVNS. This paper suggests the methodology for the ergonomic assessment of the IVNS that corresponds to the subjective measurement of the driver's mental workload by rating his or her own driving task. For this approach, Revision of NASA-Task Load Index(RNASA-TLX) was developed which translated and revised the version of NASA-TLX that is generally accepted an efficient and powerful method for evaluating the in-vehicle information systems. To verify the RNASA-TLX, an experiment was conducted in a real road situation, because the result of the laboratory approach is uncertain and has the differences from the real road test.

PURPOSE: This study was conducted to determine if the Harrison hip score (HHS), a tool for assessing hip joint function, and the Burg balance scale (BBS), a general balance assessment tool, actually reflect the balance ability of total hip arthroplasty (THA) patients 3 months after surgery. In addition, this study investigated the initial weight distribution strategy for bilateral lower extremity after THA surgery to understand the balance of THA patients. METHODS: Fourteen 3-month THA patients performed static dual standing and sit-to-stand (STS) tasks. Ground reaction forces on each leg were collected to calculate the weight distribution symmetricity (SWD), and the HHS, functional HHS (f-HHS), and BBS were evaluated. Correlation analyses between SWD and the HHS (also f-HHS) and BBS were then applied to the THA patients. RESULTS: The correlations between functional evaluation tools (HHS, f-HHS, BBS) and SWD were weak strength for the static balance task, but moderate for the dynamic STS task. Among the evaluation tools used in the present study, f-HHS was most useful for evaluation of dynamic balance ability. CONCLUSION: The results suggest that use of HHS, f-HHS, and BBS as functional evaluation tools does not provide meaningful information regarding balance ability, but that they are useful for evaluating dynamic balance ability of THA patients. The dynamic balance ability at 3 months after THA seems to be under development.

The purpose of this study was to evaluate the manual workload in repetitive wrist and finger motion. To evaluate manual workload, angular displacement of the joint, EMG of the muscle and subjective rating were studied. Both wrist motion and finger motion were studied. A screw-driving task was used for the wrist motion experiment. A keyboard typing task was used for the finger motion experiment. All finger joint angles and wrist angles were measured by an angle-measuring glove($CyberGlove^{TM}$, Virtual Technologies, Inc.). Surface EMG was recorded from FCU muscle and FDS muscle simultaneously with the angle measurement. Subjective ratings of exertion were also recorded using the modified Borg's CR-10 scale. Repetition rates of 0.5, 1, 2 motions per second were used with each task. As a result, manual workload increased with increasing repetitiveness. Peak spectral magnitude and frequency components corresponded closely with joint angular displacement amplitudes and repetition rates. Results of the correlation analysis showed that there were significant correlation among EMG, frequency-weighted motion and subjective measurement. Both EMG and frequency-weighted filtering showed consistent workload estimation with increasing task frequency. Subjective ratings showed slight over-estimation of the workload as the task frequency is increased.
