The purpose of this study was to compare the task elements categorized into required and additional man power's implemental between present and future-oriented duties of school nutrition teachers. The survey consisted of five duties, 27 tasks, 93 task elements, and 270 work details in the task elements of school nutrition teachers. A pilot-test was first conducted on nutrition teachers to confirm the survey contents, and then a main survey was performed on 240 school nutrition teachers, using a self-administrated online method, from July 16 to September 5, 2016. To compare present and future-oriented tasks, frequency analyses were conducted. Work details in the task elements were categorized into 'required' and 'additional man power's implemental', depending on school nutrition teachers' responses, based on a 50% cut-off percentage. The results showed that 13 work details among 60 work details (21.7%) in the 'Duty C. Safety and hygiene management of school foodservice', and 15 work details out of 106 work details (14.2%) in 'Duty B. Foodservice management practices' were identified as additional man power's implemental in future oriented duties. As to 'Duty A. Nutrition management', only three work details among 55 work details (5.5%) were identified as additional man power's implemental. On the other hand, all work details in 'Duty D. Nutrition diet education and counseling and 'Duty E. Reinforce professionalism' were identified as "required" as school nutrition teachers' duties. These findings imply that school nutrition teachers perceive nutrition management and education as their primary duties to the fulfill school foodservice' mission of promoting students' health and fostering students' dietary behaviors. The study offers practical and governmental implications, which can encourage school nutrition teachers to perform their primary duties.

Recently, the development of the smart home field provides a range of services to install and keep the smart home appliance in a user's residential environment pleasantly. However, the conventional system method is not convenient enough to use properly because users have to select a device and manually operate the device on their own. In this paper, we propose a system to set the priority of the devices selected by the user and proceed with the task. When a user selects a device, the system recommends an optimal device associated with the device. The system compares and sets the priority of each device, carrying out the task one by one according to the set priority. Therefore, the proposed system is expected to provide users with increased convenience and more efficient task management.

IoT has been consistently used in various fields such as smart home, wearables, and healthcare. Since IoT devices are small terminals, relatively simple wireless communication protocols such as IEEE 802.15.4 and ISO 18000 series are used. In this paper, we designed the 802.15.4q 2.4 GHz TASK physical layer. Physical protocol data unit of TASK supports bit-level interleaving and shortened BCH encoding. It is spread by unique ternary sequences. There are four spreading factors to choose the data rate according to the communication channel environment. The TASK physical layer was designed using verilog-HDL and verified through the loop-back test of the transceiver. The designed TASK physical layer was implemented in a fpga and tested using MAXIM RFICs. The PER was about 0% at 10 dB SNR. It is expected to be used in small, low power IoT applications.

Measuring performance of corporate information system has become one of the core issues in that development of the information system requires substantial amount of investments and the system works as a crucial leverage to enhance competitive edge. Most of the previous researches for performance of the information system have narrow and limited focus on such as the effect of user satisfaction and productivity. This paper suggests a model to measures the comprehensive performance which is classified as user scope (user involvement and satisfaction), operational scope (task productivity, task innovation, customer satisfaction, management control) and efficiency scope (financial performance), and to represent the relationship among the scopes by the path analysis model. Followings are conclusions from statistical hypothesis test of the model: (i) user involvement through user satisfaction has positive effect on all the performances in the operational scope, (ii) task innovation and customer satisfaction in the operational scope has statistically significant impact on financial performance but task productivity and management control do not. This conclusion indicates that task productivity and management control has the long term effect in nature, and evaluation of the information system has managerial implication when it Is measured in comprehensive performance which includes internal operational performances as well as financial performance.

Purpose : In this study, task performance and job satisfaction of nurses in non-life insurance companies were examined to improve the personnel management in their companies. Method : Data collection was done with 119 nurses in non-life insurance companies in October and November, 1999. Data analyses were performed using SPSS Win 8.0 package. Result: The Results were as follows: 1. The tasks most commonly performed by nurses were 'medical fee inspection', 'education for staves', 'management of the injured', 'management of injury and disablement'. 2. The mean score of total job satisfaction was 3.2(interaction. 3.8; professional status, 3.6; autonomy, 3.4; task requirements, 3.1; administration, 2.8; pay and advancement, 2.6). 3. Task performance was significantly correlated with job satisfaction total score(r=0.478, p<.01). The item, 'executing statistical works and data analyses related with injury and disablement', was highly correlated with job satisfaction total score(r=0.418, p<.01). 4. The amount of task performance was significantly correlated with educational background and position. The job satisfaction level significantly correlated with personal experience and position. Conclusion : To improve the work efficiency and job satisfaction in the companies, it is necessary to set the bounds of task performance and to enlarge the promotion opportunities to higher positions.

In urban vehicular edge computing (VEC) environments, one edge server always serves many task requests in its coverage which results in the resource-constrained problem. To resolve the problem and improve system utilization, we first design a general hierarchical resource management framework based on typical VEC network structures. Following the framework, a specific interacting protocol is also designed for our decision algorithm. Secondly, a greedy bidding-based multi-hop task scheduling decision algorithm is proposed to realize effective task scheduling in resource-constrained VEC environments. In this algorithm, the goal of maximizing system utility is modeled as an optimization problem with the constraints of task deadlines and available computing resources. Then, an auction mechanism named greedy bidding is used to match task requests to edge servers in the case of multiple hops to maximize the system utility. Simulation results show that our proposal can maximize the number of tasks served in resource constrained VEC networks and improve the system utility.

The notion of technological adoption such as Radio Frequency Identification (RFID) has been examined in various domains such as supply chain management, inventory management and health care. However, there are several unanswered questions surrounding how this technology is adopted in disaster management. This study attempts to explore the potential of RFID in disaster management. The notion of Task-Technology Fit (TTF) is deemed suitable for this purpose and thus used as the theoretical framework that is further validated by employing multiple case studies. The empirical findings indicate that there are six key factors influencing the decision to adopt RFID in disaster management. Some relate to aspects of RFID when it is put into practice, namely cost, compatibility, standardisation, implementation and locatability; while the other key factor relates to privacy and security aspect of information. It is hoped that the findings of this research will inform disaster management organizations to better plan the adoption of RFID for their operations.

In today's highly automated aircraft, the role of the pilot has changed from an airplane controller to a system manager. As a system manager in a cockpit, today's pilot is in charge of a management-level activity called cockpit task management( CTM). According to earlier studies, pilot errors in performing CTM activities were significant factors in a large number of aircraft accidents and incidents. The primary objective of this research was to reduce CTM-related pilot errors. A prototype pilot- vehicle interface called the cockpit task management system (CTMS) was developed and its effectiveness in improving CTM performance was evaluated. After the CTMS was implemented, it was integrated into a PC-based flight simulator to perform an experiment to evaluate its effectiveness. Eight volunteer subjects were used to collect performance data. The results of the experiment indicated that a statistically significant improvement was observed when the subjects flew with the assistance of the CTMS.
