The purpose of this study was to assess priority of educational needs for the development of curriculum based on key competencies of NCS for departments related to culinary arts in a 2-year college. In order to achieve this objective, the survey has been distributed to cooks working in hotel restaurants or restaurant companies by social network service and a total of 360 responses were analyzed excluding 18 responses. The collected surveys were analysed by using paired t-test, Borich's needs analysis and the locus for focus analysis. The results of this study were as follows. First, the difference between the level of importance and present level about key competencies recognized by cooks working in restaurant company was statistically significant in 9 fields of key competencies excluding mathematical competence. The difference recognized by cooks working in hotel was statistically significant in all 10 fields of key competencies. Second, the results of Borich's needs assessment showed that the education needs of problem solving competence were the highest, followed by interpersonal, resource management, communication, information competence. Finally, considering both Borich's needs assessment and the locus for focus analysis, cooks working in hotel restaurants recognized that educational needs of communication, interpersonal, problem-solving, information competence were the top priority, and cooks working in restaurant companies recognized that educational needs of communication, interpersonal, skill, resource management competence were the top priority. Therefore, it is necessary to develop curriculum for culinary arts specialists based on key competence of top priority.

In this paper, we propose a new scheduling algorithm that guarantees the delay property of real-time traffic, not considered in previous DWRR(Dynamic Weighted Round Robin) algorithm and also transmits non-real-time traffic efficiently. The proposed scheduling algorithm is a variation of DWRR algorithm to guarantee the delay property of real-time traffic by adding cell transmission method based on delay priority. It also uses the threshold to prevent the cell loss of non-real-time traffic due to cell transmission method based on delay priority. Proposed scheduling algorithm may increase some complexity over conventional DWRR scheme because of cell transmission method based on delay priority. However, the consideration of delay priority can minimize cell delay and require less size of temporary buffer. Also, the results of our performance study shows that the proposed scheduling algorithm has better performance than conventional DWRR scheme due to reliable ABR service and congestion avoidance capacity.

Objectives: This study evaluates and recommends the priority of policy implementation to improve the fire protection clothing management system used by firefighters and the reduction of cross-contamination from contaminated clothing at the scene of a fire. Methods: It consisted of 7 experts and conducted three interviews and two modified Delphi surveys. Through the results of previous research and interviews with experts, a plan to reduce cross-contamination of fire suits and improve the management system was first derived. An improvement plan was presented in the four areas including resources, management, fire protection related work, and laws and regulations, and the priority of policy implementation was derived by analyzing the importance and practicality of the policy at the same time. Results: As a result of the analysis, the first priority was education on the health effects of pollutants at the disaster scene for firefighters, and the second priority was the addition of SOP for the primary decontamination of on-scene personal protective equipment in preparation for the health effects of the disaster scene, and education for fire suppression and rescue workers. The next step was to improve the management system of personal protective equipment such as fire suits and develop a training course for systematic operation. Conclusions: This findings could be used in the implementation of mid- to long-term firefighting policies for the systematic operation and establishment of a systematic management system for personal protective equipment such as fire protective suits.

In spite of the proven effectiveness of ramp metering system, it has not been successfully implemented in Korean setting. The purpose of this paper is to select target locations to introduce ramp metering into the Korean expressway system. For this, domestic standards to introduce ramp metering have been presented after reviewing those of the US. The major criteria are level of service (LOS), the existence of detour route, space for queue build-up and opened ramp. 15 different locations were selected and AHP has been used to make priority among them. Intuitively, the result of priority was in accordance with the congestion and traffic volume. The core results identified in this paper is expected to be used in different cities and expressway networks elsewhere.

A Denial of Sewice (DoS) attack attempts to prevent legitimate users of a sewice from being adequately served by monopolizing networks resources and, eventually, resulting in network or system congestion. This paper proposes a Minority First (MF) gateway, which is capable of guaranteeing the Quality of Service (QoS) of legitimate service traffic under DoS situations. A MF gateway can rapidly determine whether an aggregated flow is a congestion-inducer and can protect the QoS of legitimate traffic by providing high priority service to the legitimate as aggregate flows, and localize network congestion only upon attack traffic by providing low priority to aggregate flows regarded as congestion-inducer. We verify through simulation that the suggested mechanism possesses excellence in that it guarantees the QoS of legitimate traffic not only under a regular DoS occurrence, but also under a Distributed DoS (DDoS) attack which brings about multiple concurrent occurrences of network congestion.

The rapid growth of the Internet has stimulated the development of various new applications and services, and the service providers and the Internet users now require different levels of service qualities rather than current best-effort service which treats all incoming packet equally. Therefore, next generation routers should provide the various levels of services. In order to provide the quality of services, incoming packets should be classified into flows according to pre-defined rules, and this should be performed for all incoming packets in wire-speed. Packet classification not only involves multi-dimensional search but also finds the highest priority rule among all matching rules. Area-based quad-trie is a very good algorithm that constructs a two-dimensional trie using source and destination prefix fields. However, it performs the linear search for the prefix length, and hence it does not show very good search performance. In this paper, we propose to apply binary search on length to the area-based quad-trie algorithm. In improving the search performance, we also propose two new algorithms considering the priority of rules in building the trie.

This paper suggested to solve ATM switch performance and service rate which was input buffer managed scheme in ATM network with burst traffic characteristics, For this purpose, ATM multiplexer is prepared before sending for handling burst random input traffic to multiplex and then sort based on cell inter-arrival time and cell processing due time which had been marked after that. The server looks for cell header with the most shortest due time and sends it, thus it is satisfied that real time traffic for instance CBR and rt-VBR was guaranteed cell processing time to send fast than non real time traffic. For analysis of ATM switch performance with cell processing due time and priority, each output port has divided into four different virtual buffer and each buffer has assigned different cell inter-arrival time and processing due time according to ATM Forum for example CBT/rt-VBR, nrt-VBR, ABR and UBR and showed it’s optimal service parameters then analyzed service rate behaviors according to each traffic characteristics.

The purpose of this study was to provide the basic information necessary to efficiently run a coffee shop. It comparatively analyzes the relative importance and satisfaction of side menu selection characteristics through analyses on customer importance-satisfaction when selecting a side menu as well as their usage behavior of the side menu at coffee shops. According to reason price the analysis result on the differences in the coffee shop side menu importance and satisfaction, there was a difference because the importance of selecting a side menu was higher for the attributes of taste, health, packing & appearance, economics and personnel service compared to satisfaction among which the price of a side menu was found to be the top priority for improvement. The significance of coffee shop side menu for the respondents prior to usage as well as their satisfaction after usage was evaluated in order to comparatively analyze the relative importance and achievement of each characteristic through the IPA. The result indicated that the variables positioned in the Concentrate Here area (II) were related to economic feasibility such as reasonable price, appropriate price of set menu, telecommunication company affiliated service and coupon usage and point accumulation. As for the Keep up the Good Work area (I), there were many variables regarding personnel service including taste of side menu, blending with coffee, clean packing, clean packaging, staff's side menu knowledge, staff's quick response, staff's politeness and staff's sincere response. As for the variables in the Low Priority area (III), health variables on health such as nutritional value, eco-friendly food materials and calories were observed.

As the interest in VANET is increased, a study on the beacon message transmission between vehicles is actively being made. IEEE 802.11p/1609.4 standard is based on a multichannel system consisting of multiple service channels (SCH) and a control channel (CCH). Multiple SCHs are defined for nonsafety data transfer, while the CCH is used to broadcast safety messages called beacons and control messages (i.e., service advertisement messages). However, most messages broadcast in the only one CCH belong to safety application that must be contested in dense vehicular network. This paper suggests safety message transfer algorithm in dense vehicular congestion. The proposed algorithm is that the priority of safety messages is decided by decision tree and messages are stored in proper queues according to their priorities. Then, safety messages with higher priorities are sent in turn by CCH in the assigned time. The proposed algorithm decreases the beacon transmission delay and increase on the probability of a successful beacon reception in an IEEE 802.11p/1609.4-based network.
