  • The objective of this study was to determine whether there are differences in hand muscle activities (APB : abductor pollicis brevis, ED : extensor digitorum, ECU : extensor carpi ulnaris, and EI : extensor indicis) and subjective discomfort according to the three mouse sizes (small, medium, large) and two task types (pointing and scrolling). The mouse size and task type showed significant interaction effects on the total NEMG (p = 0.004) and on the NEMG of the abductor pollicis brevis muscle (p = 0.001). The total NEMG and the NEMG of APB showed the highest value in the 'scrolling' task using the 'small' mouse. However, the NEMG of the EI was different according to the mouse size, and the 'small' mouse showed the lowest value. The subjective discomfort was the lowest in the 'medium' mouse, and all nine subjects preferred the 'medium' size. The hand-size related anthropometric variables showed different correlations according to the task type and mouse size with the NEMGs and subjective discomfort. The results of this study could be used as a basic information for the determination of the proper mouse size according to the hand size.

  • In this paper, we propose a new bankruptcy algorithm. The proposed algorithm is comprised of four tasks. Task A is the procedure of soliciting bids, Task B is the procedure of allocating claims, Task C is the procedure of trading claims, and Task D is the procedure of exercising options and holding shareholders' meeting. Tasks A, B, and D are based on Bebchuk(1988) and Aghion, Hart, ad Moore(1992). This paper adds Task C, the procedure of trading claims. Claims are in the form of options which are written on the new shares of the bankrupt firm. Trading options expedites the process of finding the value of the bankrupt firm, and also it mitigates the problem of incomplete capital market by expanding the pool of new investors.

  • The purse of this study is to identify whether ethical values of Korean nurses are deontological or utilitarian. Nurse's ethical value questionnaire was developed from review of the literature and interview of nurses in the clinical settings. Ethical problem are categorized into four areas 1) human life 2) nurse-patient relationship 3) nurse-nursing task relationship 4) nurse-collegue relationship The data were obtained from 250 nurses in the clinical settings from Jun. to July in 1998 using the ethical value questionnaire developed by Lee (1990). The analysis of data was done by Pearson's correlation coefficient, t-test and anova. The results of this study were as follows : 1. The ethical values of human life slightly took up the position of utilitarian. 2. The ethical value of nurse-patient relationship slightly took up the deontological position. 3. The ethical value of nurse-nursing task relationship slightly took up the deontological position. 4. The ethical value of nurse-collegue relationship greatly took up the deontological position. 5. The ethical values of nurses related to demographic characteristics of age, marital status, position. Therefore it is suggested that new strategies and continuing education programs be established to help clinical nurses formlulate higher ethical values.

  • The purpose of this study was to investigate the effect of academic self-efficacy, task value, behavioral participation, cognitive participation, emotional participation, and initiative participation on learning satisfaction in 462 college students who took a flip learning class. Results, As for the direct effect of variables affecting learning satisfaction, behavioral participation was the largest factor, followed by initiative participation, task value, emotional participation, and academic self-efficacy. These variables explained 86% of learning satisfaction. Academic self-efficacy and task value had an indirect effect on learning satisfaction through behavioral, emotional, and proactive participation. In the multi-group moderating effect with the upper-middle class (B+ or higher) and the lower-middle class (below B) group as the moderating variables, there was a partial moderating effect because the path coefficients of leading participation and learning satisfaction differed between the groups. It is necessary to seek various ways to increase the degree of participation in learning and to develop an intervention strategy through a program tailored to each individual.

  • Objectives: The main purpose of this study was to assess firefighters' daily personal noise exposure and explore noise levels related to specific tasks and their contributions to total noise exposure using 24-hour full-shift noise exposure measurements with task-based data. Methods: Noise exposure was assessed for eight firefighters (two rescuers, two drivers, and four suppressors) using time-activity diaries. We collected a total of 24 full-shift personal noise sample sets (three samples per a firefighter). The 24-hour shift-adjusted daily personal noise exposure level (Lep,d), eight weekly personal noise exposures (Leq,w), and 40 task-specific Leq values (Leq activity) were calculated via the ISO/NIOSH method. Results: The firefighter noise-sample datasets showed that most firefighters are exposed to noise levels above EU recommended levels at a low-action value. The highest noise exposure was for rescuers, followed by drivers and suppressors. Noise measurements with time-at-task information revealed that 82.3% of noise exposure occurred when checking equipment and responding to fire or emergency calls. Conclusions: The results indicate that firefighters are at risk of noise-induced hearing loss. Therefore, efforts at noise-control are necessary for their protection. This task-specific noise exposure assessment also shows that protective measures should be focused on certain tasks, such as checking and testing equipment.

  • With the rise of the Al wave, task-oriented dialogue systems have become one of the popular research directions in academia and industry. Currently, task-oriented dialogue systems mainly adopt pipelined form, which mainly includes natural language understanding, dialogue state decision making, dialogue state tracking and natural language generation. However, pipelining is prone to error propagation, so many task-oriented dialogue systems in the market are only for single-round dialogues. Usually single- domain dialogues have relatively accurate semantic understanding, while they tend to perform poorly on multi-domain, multi-round dialogue datasets. To solve these issues, we developed a paddle-based multi-domain task-oriented Chinese dialogue system. It is based on NEZHA-base pre-training model and CrossWOZ dataset, and uses intention recognition module, dichotomous slot recognition module and NER recognition module to do DST and generate replies based on rules. Experiments show that the dialogue system not only makes good use of the context, but also effectively addresses long-term dependencies. In our approach, the DST of dialogue tracking state is improved, and our DST can identify multiple slotted key-value pairs involved in the discourse, which eliminates the need for manual tagging and thus greatly saves manpower.
