IEEE802.11g VoWLAN (Voice over Wireless LAN) 단말기는 802.11b 전용 단말기에 비해 통화시간이 30 % 이상 감소하는 문제점이 있어 통화시간이 문제로 대두되고 있다. 일반적으로, 802.11g에서는 멀티캐리어 방식인 OFDM (Orthogonal Frequency Division Multiplexing) 변조방식을 사용하여 54 Mbps속도로 전송하기 때문에 기존의 802.11b MAC (Medium Access Control) 전송방식과 비교하여 통화시간을 만족시키는 것이 어렵다. 본 논문에서는 802.11g 규격을 적용한 단말기에서 통화중 Power Save 방법으로 Holdover Time을 처음으로 제안하므로 통화시간을 만족시킨다. 다만, 통화 단말기 수 증가에 따른 네트워크 혼잡으로 경합 창 (contention window)이 많이 발생하여, Back-off 수 증가로 인한 통화품질(QoS)의 문제가 발생하지만, QoS 해결 방안으로 다운 링크 시 802.11 G.711 Sequence Number를 단말기 MAC 단에서 분석하여 손실율에 따른 Holdover Time을 가변 하는 방법을 제안하므로 이 문제를 해결한다. 802.11b/g 소비전류 분석과 통화 단말기 증가에 따른 네트워크 혼잡에 의한 MAC 파라미터 성능을 분석하며, VQT장비와AiroPeek를 이용하여 실제적인 데이터를 분석한다.

The facade, an exterior material of a building, is one of the crucial factors that determine its morphological identity and its functional levels, such as energy performance, earthquake and fire resistance. However, regardless of the type of exterior materials, huge property and human casualties are continuing due to frequent exterior materials dropout accidents. The quality of the building envelope depends on the detailed design and is closely related to the back frames that support the exterior material. Detailed design means the creation of a shop drawing, which is the stage of developing the basic design to a level where construction is possible by specifying the exact necessary details. However, due to chronic problems in the construction industry, such as reducing working hours and the lack of design personnel, detailed design is not being appropriately implemented. Considering these characteristics, it is necessary to develop the detailed design process of exterior materials and works based on the domain-expert knowledge of the construction industry using artificial intelligence (AI). Therefore, this study aims to establish a detailed design automation algorithm for AI-based condition-responsive exterior wall panels and their back frames. The scope of the study is limited to "detailed design" performed based on the working drawings during the exterior work process and "stone panels" among exterior materials. First, working-level data on stone works is collected to analyze the existing detailed design process. After that, design parameters are derived by analyzing factors that affect the design of the building's exterior wall and back frames, such as structure, floor height, wind load, lift limit, and transportation elements. The relational expression between the derived parameters is derived, and it is algorithmized to implement a rule-based AI design. These algorithms can be applied to detailed designs based on 3D BIM to automatically calculate quantity and unit price. The next goal is to derive the iterative elements that occur in the process and implement a robotic process automation (RPA)-based system to link the entire "Detailed design-Quality calculation-Order process." This study is significant because it expands the design automation research, which has been rather limited to basic and implemented design, to the detailed design area at the beginning of the construction execution and increases the productivity by using AI. In addition, it can help fundamentally improve the working environment of the construction industry through the development of direct and applicable technologies to practice.

The purpose of this study is 1) to clarify that the house is no long the safe place through the cases of the senior safety accidents and to argue the need for housing repair and 2) to present the minimum standards for housing repair by comparing the cases here as well as the abroad and to back up the standards with the current senior housing environment 300 people at least 60 years old living in Seoul$\cdot$Metropolitan area were interviewed using the structured questionnaire. As the result, the following conclusions were made: 1. There was high accident rates of the senior residents due to physical deficits within the house, causing excessive medical cost and decreased housing satisfaction. This problem can be sufficiently prevented by housing repair which can not only solve the safety problem but also support self sufficient living for the senior residents. 2. Proper housing repair required the architectural know how as well as the expertise knowledge of the physical characteristics of the senior people. Therefore, it is essential to secure the professional (i.e., occupational therapist) who can analyze the needs of the senior residents and evaluate and/or predict the obstacles during repair. Furthermore, development and distribution of the standardized manual are also needed. 3. The minimum standard for housing repair could be approached in view of 'barrier-free' concept. First, the bumps should be removed, slippery prevented, and safety grab-bar installed for safety. Second, the entrance should be widened and the bathroom and kitchen restructured to support for the senior residents' self sufficiency. To make housing repair policy more efficient, the legal basis is required. It can be incorporated into the existing senior citizens 'Welfare Act' or the 'Senior Residents Medical Insurance' which will be effective starting in 2007.

In the ship building industry various problems of erection is counterfeited due to formation of bottle necks in the block erection flow pattern This kind of problems cause accumulated problems in real-time erection right on the floor, When such a problem is approached, a support data of the entire erection sequence should be available, Here planning is done by reasoning about the future events in order to verify the existence of a reasonable series of actions to accomplish a goal. This technique helps in achieving benefits like handling search complications, in resolving goal conflicts and anticipation of bottleneck formation well in advance to take necessary countermeasures and boosts the decision support system, The data is being evaluated and an anticipatory function is to be developed This function is quite relevant in day to day planning operation. The system updates database with rearrangement of off-critical blocks in the erection sequence diagram, As a result of such a system, planners can foresee months ahead and can effectively make decisions regarding the control of loads on the man, machine and work flow pattern, culminating to an efficient load management. Such a foreseeing concept helps us in eliminating backtracking related adjustment which is less efficient compared to the look-ahead concept. An attempt is made to develop a computer program to update the database of block arrangement pattern based on heuristic formulation.

Objectives: Family caregivers (FCs) are often the primary source of social and emotional support for cancer patients and play a major role in how well they manage their illness. The aim of this study was to create an Turkish version of the Quality of Life - Family Version (QOL-FV) and to evaluate its psychometric properties in a sample of FCs of cancer patients. Materials and Methods: This study was carried out with the FCs of 218 patients with cancer. Data were collected with a Demographic Questionnaire and the QOL-FV and The Multidimentional Scale of Perceived Social Support (MSPSS). The QOL-FV was developed by Ferrell and Grant and is composed of 4 subdimensions. Linguistic validity, translation, back translation, and content validity were tested with expert opinions. Test-retest reliability, and internal consistency reliability were assessed. Construct validity was tested by factor analysis and with the scale of the MSPSS. Results: The family caregivers were between the ages of 46-56 (32.6%), a great number of them being male (52.8%). The scale is made up of four subdimensions. The result of the test-retest analysis of this scale was calculated as r:0.86. As a result of the reliability analysis, six items were eliminated from the scale, factor analyses were fulfilled according to varimax transformation through the method of principal components. Four new subdimensions were restrustured at the end of the analysis. The scale of Cronbach ${\alpha}$ coefficient was calculated as 0.90. Concurrent validity showed low correlations with the MSPSS (r=0.29). Conclusions: The QOL-FV, adapted into Turkish, was found to have sufficient reliability and validity.
