멀티미디어 시스템에서 사용자에게 고품질의 서비스를 제공하기 위해서는 자원을 효율적으로 관리해야 한다. 이를 위해서는 서비스의 적절한 품질 유지에 필요한 요구사항들의 범위를 정하고 그 범위 내에서 융통성 있는 서비스를 제공하도록 하여야 한다. 따라서 각 멀티미디어 응용은 다양한 서비스 품질을 기술할 수 있어야 하며 운영체제에는 서비스 품질 관리자가 있어 각 응용의 서비스 품질을 보장하여야 한다. 서비스 품질 관리자는 멀티미디어 응용에게 서비스 품질 기술에 대한 인터페이스를 제공하고, 각 응용의 서비스 품질 기술에 따라 시스템의 자원을 할당할 수 있어야 한다. 또한 응용의 요청에 대한 수용 여부를 결정하는 기능과 각 응용의 서비스 품질을 보장할 수 있도록 서비스 품질의 집행 기능도 가져야 한다. 본 논문에서는 멀티미디어 시스템에서 멀티미디어 응용의 서비스 품질을 보장하는 서비스 품질 관리자를 제안한다.

The quality control personnel of the construction work shall establish and execute the quality control plan or the quality test plan and check the qualification of the used materials according to the process, the management of the test and inspection equipment, the quality education, the own quality inspection and measures. Management and quality test of Korea and plays an important role in preventing accidents. However, related organizations did not explicitly disclose their roles in quality testing and quality control tasks while changing the names of quality control personnel to test personnel and quality managers when revising related laws and regulations and the application of labor costs. Therefore, a research of this is needed to improve conflicting situation. In this study, the ambiguous title relation to the quality control persons is improved to meet the requirements of the construction work based on related laws and regulations, and each role and title is classified as 'quality tester' and 'quality manager'. In other words, the person who carries out the quality test of the "Construction Quality Test Standard" specified in the Guideline for Quality Management of Construction Projects shall be the "Quality Tester" and the person who performs the quality control plan establishment and execution work specified in the Enforcement Rule of the Construction Technology Promotion Act shall be referred to as the 'Quality Manager'.

In order to calculate the quality management cost of construction work, the process must conform to relevant laws and regulations. In details, the cost of the various items such as quality test fee and quality control activity cost are required to be calculated. Regarding the quality management costs, the labor cost is applied to the quality examination fee and the calculation unit quantity in the construction quality management duties. The application of the unit price of the labor cost stipulates that Construction Association of Korea and Korea Engineering & Consulting Association apply the unit price which is surveyed and published. However, in the related laws and regulations, the standard of the quality manager and quality tester is not clear. This accounts for the confusion in the cost of construction management and the cost of labor. In the current law, the allocation standard of quality control personnel is specified according to the size of the construction, but the standard of placement of quality testers is not specified. At the construction site, there is no assignment criteria manpower for quality testers except quality managers, or very little work is being done. The quality control personnel conducts the quality test work to be carried out by the quality tester, and this carrying out heavy work. Therefore, it is difficult to maintain quality control activities. In this study, the labor cost of quality management expenses and the allocation criteria of quality managers and quality testers are established and presented for the purpose of securing the quality of the construction work and preventing the construction work. It is stipulated that the standards of the relevant laws and regulations, which are not clear, should be classified into quality control personnel and quality testers according to the size of the construction. Based on the unit price of Korea Engineering & Consulting Association, the personnel expenses of quality managers and quality testers are proposed to apply the unit price of engineer (professional engineer, specialist, advanced, intermediate, beginner) and skilled technicians (advanced, intermediate, beginner).

현재의 인터넷망을 이용하여 음성, 화상 정보를 실시간으로 이용하고자 하는 다양한 응용이 시도되어 왔다. 인터넷망이 최선의 노력(best effort)만을 제공하기 때문에 발생되는 신뢰성과 지연의 문제는 이미 많은 연구가 있어왔고 현재 어느 정도의 서비스 품질을 획득하여 인터넷폰과 같은 서비스가 실제로 이용되고 있다. 그러나 무선 통신의 경우는 이에 더하여 무선 구간에서의 자원 할당의 문제가 남아 있다. 본 연구에서는 코어 망으로 인터넷 프로토콜을 사용하는 차세대 망에서, 무선 이동단말 간의 멀티미디어 서비스가 가능하도록 효율적인 주파수 할당을 지원하는 QoS 관리자를 설계하였다. 제안한 QoS(Quality of Service) 관리자는 요구 대역폭이 다른 멀티미디어 호 요청에 대해 융통성 있는 주파수 할당이 가능하도록 대국의 QoS 관리자와의 협상을 통해 제한된 범위 내에서 서비스 품질을 조절하여 보다 높은 서비스 수준을 유지할 수 있도록 한다.

In this study, we attempted to derive major management factors related to the quality control of formwork and identified differences in the perceptions of construction engineers, construction managers, and field workers about the importance and performance of the derived factors. As a result of the study, 18 management factors related to the formwork were derived. Among the derived factors, the field workers placed importance on the factors that influence the detailed process of the formwork, while construction engineers placed importance on the factors related to the judgment of the progress and completion of the construction. The construction managers placed importance on the factors that affect the quality of the building frame. Based on the results of this study, it is expected that a plan to improve the quality of formwork that accepts the various opinions of each participant will be established.

Currently, the quality management, safety management and environment management of domestic construction work does not form a infrastructure for integrated control which have been developed according to the unique characteristics based on respective the law. In other words, the quality manager and safety manager of human resources is set to a legal arrangement personnel, but environment manager of human resources is not. In addition, quality management standard is to perform the work to PDCA(Plan-Do-Check-Action) system which is reflected in all of the requirements of KS A ISO 9001 standard, but safety management plan and hazard harmfulness prevention plan are not properly reflected P(Plan), C(Check) and A(Action) system and focusing on only 4 section Do(D) in KOSHA 18001 standard requirement. Moreover environmental management plan is not even established requirement. Through examining the operation practices of an advanced nation prior to building the integrated control standard for construction work qualify safety.environment, the possibility of applying domestic is reviewed, and then this study is going to research the operation practices of Singapore.

다양한 유 무선 통신 환경에서 사용되는 많은 종류의 사용자 단말은 프로세싱 능력과 가용 대역폭의 한계 등의 제한된 성능이 있지만 사용자는 일반 PC와 같은 성능의 응용 서비스를 요구한다. 하지만 서비스 제공자는 모든 단말 종류에 맞는 서비스를 제공하기 힘들다. 본 논문에서는 사용자 환경과 단말의 성능을 고려하지 않고, 전달 망의 자원 예약만으로 서비스를 제공하는 경우의 문제점을 개선하는 서비스 제어 관리자를 제안한다. 서비스 제어 관리자는 사용자 환경과 단말 능력에 맞는 서비스를 제공하기 위해서 서비스 품질 협상을 수행한다. 또, SIP 프락시 기능을 가지고 기존에 제안된 SIP 프로토콜 기반 서비스 제어 관리자들과의 연동한다. 이 때, 서비스 제공 과정에서 효율적으로 메시지를 전달하기 위해 새롭게 SIP 헤더를 제안한다.

Korean foreign direct investment (FDI) firms procure cheap raw materials, produce goods in developing countries featuring low rent and labor costs, and sell goods in world market. In this regard, global supply chain management is important to Korean FDI firms. The objective of this study is to analyze gaps in the performance of reliability and quality of supply chain orientations. To achieve this objective, this study confirms theoretical relationships between variables through prior research, selects measuring variables, and analyzes data collected from Korean FDI firms. Results are as follows; First, there is a gap in reliability performance among the levels of supply chain orientation. Managers should check the level of their supply chain orientation and make strategic and structural efforts to improve reliability performance. Second, there is a gap in quality performance among the levels of supply chain orientation. To improve quality performance, managers should identify the level of their supply chain orientation. In addition, managers can enhance quality performance on the basis of strategic and structural efforts.
