The facts of job satisfaction and their perceived importance among elementary school foodservice dietitians were assessed. The survey instrument consisted of three parts: the job satisfaction survey was used to measure facets of job satisfaction and the level of total satisfaction; perceived importance questions for corresponding job facets; and demographic items. A survey of school food service operations was undertaken and detailed information was collected from 170 dietitians. The collected data were processed using the SPSS package program for descriptive analysis and analysis of valiance. School foodservice dietitians' importance and satisfactions scores on their job and working environment were 4.25 and 2.83, respectively. The respondents rated the subscales of 'communication' and 'nature of work' the highest and the subscales of 'pay' and 'working environment' the lowest The results of facet satisfaction scores and corresponding perceived importance scores were paired to be plotted on the Importance-Performance Analysis Grid. IPA grid was used to provide a strategy for food service managers to counteract dietitian dissatisfaction.

This paper proposes a tension control to compensate friction loss using on-line friction torque observer for a continuous strip processing line. Friction loss of roller results in significant deviation of strip tension, accordingly it has an influence on the operation of other adjacent rolls. To avoid tension variation of the strip, a friction torque observer is designed in adjacent roll, which operates in speed control mode. The observed torque is added to the torque limit reference of the pay-off reel for on-line compensation of both friction loss and acceleration/deceleration torque at the same time. The simulation and experimental results show improvement of tension control performance by the proposed friction compensation method.

Spectral efficiency of current two-phase cooperative communications protocols is low since in the second time the relay forwards the same signal received from the source to the destination, the source keeps silent in this time. In this paper, we propose a novel cooperative communications protocol where the signal needed to transmit to the destination is sent in both phases, the source and the relay also transmit different signal to the destination thus no loss of spectral efficiency. This protocol performs signal selection based on log-likelihood ratio (LLR) at relay and maximum likelihood (ML) detection at destination. While existing protocols pay for a worse performance than direct transmission in the low SNR regime which is of special interest in ad hoc networks, ours is better over the whole range of SNR. In addition, the proposal takes advantages of bandwidth efficiency, long delay and interference among many terminals in ad hoc network. Simulation results show that the proposed protocol can significantly save total energy for wireless ad hoc networks.

Purpose: This study aimed to investigate the work and job satisfaction of military emergency medical technicians (EMTs). Methods: We selected 122 military EMTs who participated in the refresher education in 2012. This study was conducted from November 12 to December 21, 2012. Results: The most frequent duties of military EMTs were scene assessment, cardiopulmonary resuscitation, surgical treatment, prehospital first-aid, transfer to the hospital, education, and call response. The air force and navy EMTs had better performance than the army EMTs. As for job satisfaction, the work itself ranked highest, whereas payment ranked lowest. Conclusion: The scope of the work of the military EMTs varied in the 14 fields of work but should be considered for further evaluation. In order to increase the job satisfaction of EMTs, their work conditions should be improved such as through salary increase and extra pay for those with professional certificates.

Purpose: In this study, effects of positive, negative, and mixed verbal feedback were examined for accuracy of self-assessment, emotional responses, self-efficacy, and perceived quality of feedback in skill performance assessment. Methods: Participants were a convenience sample of 104 second-year nursing students who had completed their fundamentals of nursing class. Participants were assigned randomly to a positive, a negative or a mixed feedback group. All participants completed the performance measure and then received the assigned the type of feedback from an evaluator. After delivery of feedback, they assessed their own performance using the same sheet as the evaluator and completed the survey for emotional response, self-efficacy for learning, and quality of feedback. Results: There were no significant differences in accuracy of self-assessment and perceived quality of feedback among the three groups ($x^2=4.74$, p=.094; $x^2=3.30$, p=.192, respectively). The negative feedback group had significantly lower self-efficacy and positive emotions and more negative emotions than the other two groups (F=9.43, p=.009; $x^2=16.29$, p<.001; $x^2=5.69$, p=.005, respectively). Conclusion: Negative feedback can affect emotions and motivations for learning in nursing students and may interfere with the effectiveness of feedback, so instructors should pay more attention when providing negative feedback. Mixed feedback with an effect similar to positive feedback could be an alternative.

This study primarily concerns the seller's right to require performance under the United Nations Convention on International Sale of Goods(1980) (here-in-after the CISG). By virtue of art. 62 of the CISG, the seller may require to pay the purchase price, take delivery or perform his other obligations. The right is known as a process whereby the aggrieved seller obtains as nearly as possible the actual subject-matter of his bargain, as opposed to compensation in money for failing to obtain it. The study describes and analyzes the provisions of the CISG as to the seller's right to require performance, focusing on the questions of what the seller can require the buyer to perform, and what the restrictions of his right to require performance are. It particularly deals with main controversial issues among scholars as to whether art. 28 of the CISG is applied to the seller's action for the price and so that it opens the door domestic traditions and national preconditions that prevent judges and enforcement authorities in some contracting states, and whether the seller's to require performance is subject to the duty to mitigate loss within the meaning of art. 77 of the CISG. On the basis of the analysis, the study puts forward the author's arguments criticizing various the existing scholars' views. In addition, this study provides legal and practical advice to the contracting parties when it is expected that the CISG is applicable as the governing law.

The purpose of value analysis is to assist each to approach nearer enough to this goal to provide substantial competitive and profit advantages. It provides planned and disciplined thought and act ion which hel ps identify unnecessary cost throughout the product or process cycle. Value analysis is a precise, disciplined, one-purpose thinking process. Its one purpose is to retain all the performance and aesthetic factors which now exist In the product, process or services, which the customer wants and is willing to pay for : and through disciplined thinking procedures, to put together Practical alternatives which will accomplish them at still lower cost. Value in a product or service is the reward for appropriate performance and appropriate cost Value analysis must therefore employ techniques which will sensitize any "lacking" area so that the need can be identified and satisfied. As the business begins to see the benefit of the activity, additional value analysts consultants may be added. This will provide more penetration in the three identified areas, of top managers group, individual value analysis consultants and senior member who organizes value analysis work, and besides, additional abilities will be secured.e secured.

This study describes the buyer's remedies regarding defects in title under CISG. Although CISG stipulates the seller's liability for the delivery of conforming goods physically at Art. 35 and legally at Art. 41 and Art. 42 respectively, the buyer's remedies are not distinguished between non-conformity governed by Art. 35 and defects in title governed by Art. 41 and Art. 42. If the seller does not fulfill his obligation under Art. 41 and Art. 42 to deliver goods which are free from third party claims, the buyer should pay attention to which remedies are available under CISG. Under CISG, for defects in title in the delivered goods, the buyer is entitled to require performance in Art. 46 (1) unless he has resorted to a remedy which is inconsistent with this requirement, to declare the contract avoided by strictly limiting the situation in which the failure by the seller to perform his obligation amounts to a fundamental breach of contract in Art. 49, to claim damages in Art. 74, and to suspend the performance of his obligation where it becomes apparent that the seller will not perform a substantial part of his obligation in Art. 71 (1). Unlike Art. 35 non-conformity, the buyer may not require delivery of substitute goods under Art. 46 (2), claim repair under Art. 46 (3), and declare price reduction for title defects under Art. 50.

From Feb. 2006, the ventilating systems with air exchange rate of over 0.7times/hour are installed at the apartment houses (over 100 units). Installation cost and maintenance cost are very important factors for ventilating system because consumers have to pay the expenses of that system. Especially small apartment needs more considerations because small apartment is comparatively the economically weak part. The purpose of this study is to the performance evaluation of the hybrid ventilation system for small apartment houses. Hybrid system 1 consists of natural ventilation system and duct type exhaust diffusers. Hybrid system 2 has natural ventilation system and toilet exhaust system with static pressure fan. Infiltration of test apartment houses with ventilation system is under 0.1 times/hour. Mean air age of hybrid system 1 is 1.52 hours and hybrid system 2 is 1.42 hours. Mean ventilation effectiveness of hybrid system 2(93%) is higher than that of hybrid system 1(81%).
