As the Internet service is expanding rapidly, portal sites, a gateway tn the net, are attracting increasing attention these days. As the Internet service has expanded rapidly, so has the interest for portal sites,, which serve as a gateway to the net. Despite the tendency, however, research on a measure by which to evaluate the quality of portal sites or development of such measures has not been fully pursued. As online services, faced with profitability, are considering 'charge per view', the development of a set of quality evaluation measures for portal services will prove to become a valuable instrument in constructing competitive strategies that are vital for survival and growth of a firm. In that regard, this study aims to develop a set of evaluation measures for Internet portal sites by empirically investigating the most common offline measures for quality of services, SERVQUAL, retail SERVQUAL and other evaluation measures for IT-related online services. Moreover, the study offers the strategic implications of the defined measures.

This paper deals with a comparative evaluation of the reliability of control rod drive mechanisms including their driving methods for nuclear power plants. Basically there exist two types of electromagnetic-jack-type drive mechanisms in commercial use that are called as Control Rod Drive Mechanism and Control Element Drive Mechanism. Each type has corresponding drive sequence to make the movements of insertion and withdrawal. A state-space model is derived for each model graphically. Then the evaluation of the reliability is carried out on the programming tool called SHARPE. The evaluation does not give any meaningful numerical values for the reliability but just shows a relative degree to each other in view of reliability.

Because of increased nonpoint source runoff potential at highland agricultural fields of Kangwon province, effective agricultural management practices are required to reduce the inflow of sediment and other nonpoint source pollutants into the water bodies. The watershed-scale model, Soil and Water Assessment Tool (SWAT), model has been used worldwide for developing effective watershed management. However, the SWAT model simulated sediment values are significantly affected by the number of subwatershed delineated. This result indicates that the SWAT estimated watershed characteristics from the watershed delineation process affects the soil erosion and sediment behaviors. However, most SWAT users do not spend time and efforts to analyze variations in sediment estimation due to watershed delineation with various threshold value although topography falsification affecting soil erosion process can be caused with watershed delineation processes. The SWAT model estimates the field slope length of Hydrologic Response Unit (HRU) based on average slope of subwatershed within the watershed. Thus the SWAT ArcView GIS Patch, developed by using the regression relationship between average watershed slope and field slope length, was utilized in this study to compare the simulated sediment from various watershed delineation scenarios. Four watershed delineation scenarios were made with various threshold values (700 ha, 300 ha, 100 ha, and 75 ha) and the SWAT estimated flow and sediment values were compared with and without applying the SWAT ArcView GIS Patch. With the SWAT ArcView GIS Patch applied, the simulated flow values are almost same irrespective of the number of subwatershed delineated while the simulated flow values changes to some extent without the SWAT ArcView GIS Patch applied. However when the SWAT ArcView GIS Patch applied, the simulated sediment values vary 9.7% to 29.8% with four watershed delineation scenarios, while the simulated sediment values vary 0.5% to 126.6% without SWAT ArcView GIS applied. As shown, the SWAT estimated flow and sediment values are not affected by the number of watershed delineation significant compared with the estimated flow and sediment value without applying the SWAT ArcView GIS Patch.

As the standard of living has raised and the local self-governing body has enforced, cultural facilities have been increased in local areas. These cultural facilities should be designed to consider various users. However, most facilities were designed to focus on size or visual expressions. Therefore, this study was intended to evaluate common spaces of two cultural centers in local area from the universal design point of view. Two cultural centers located in large apartment complex were selected. The evaluating tool consisted of 46 elements related to universal design. The common space were pathway to entrance, parking lot, entrance, all over building, corridor, and restroom. Each 100 users of these two cultural centers evaluated them using by 5-point Likert scale. The results were as follows; The users rated them positively, but not highly. This means that some improvement were needed. Generally, the consideration for upgrading the quality of design such as material, pattern and color needed, and for various users including wheelchair users and seniors were needed. Also, when considering the users' behavior pattern and purposes, installing canopy over entrance, and providing seating places at corridor or pathway were needed.

UAV(Unmanned Aerial Vehicle, 드론)는 재난재해, 유통, 물류 등 다양한 분야로의 활용가치가 증대되고 있으나, 관련 법규의 미비, 사생활 침해 등이 산업성장의 저해요소로 지적되고 있다. 이에 앞으로 전개될 UAV의 융합서비스에 대해 규제 프레임워크를 기반으로 규제방향성을 제시하였다. 기술관점에서는 아키텍쳐 설계에 대한 규제, 시장관점에서는 제한된 영역에서의 서비스 병행운영, 법적으로는 입법 예고된 영상정보보호법 하의 사전규제보다는 사후평가 중심, 사회규범 관점에서는 사회적 공감대 형성을 위한 노력을 통해 UAV기반 융합서비스 조기 정착에 기여할 것으로 생각한다.

The point spread function (PSF) of an optical system is in general defined as a two-dimensional intensity distribution which results from a single point source at infinity. It is an important key for the evaluation of the optical performance of an astronomical telescope. The PSFs of the soft X-ray telescope (SXT) aboard Yohkoh were measured in a wide range of the field-of-view under the in-flight configuration at White Sands Missile Range prior to launching the satellite. It has been known that the SXT PSF has a sharp peak at the core and the intensity drops very fast as it goes distant from the center. Due to the combination of this sharp peak at the PSF core and the effect of undersampling by a large pixel size, a carefully designed method is requested in the examination of the PSF data. The pattern of the SXT PSF is determined by the fitting of a mathematical functional form to the pre-launch experimental data. The elliptical Moffat function has been adopted for the evaluation of the SXT PSF. It is revealed from our study that the SXT PSF shows a peculiar characteristics, and thus a careful consideration on the undersampling effect and also a proper choice of statistics are necessary for the determination of the best fit function of the PSF. Details on the on- and off-axis SXT PSF in the field-of-view will be introduced and discussed in our presentation.

목 적 : 본 연구에서는 표준인 AP-WB(Weight-Bearing AP) 촬영법과 MTP(Semiflexed or metatarsophalangeal) 촬영법을 소개하고 판독 시 중요하게 여기는 관절간격과 신생골 묘출에 따른 항목을 각각 비교 고찰하여 골관절염 환자의 진단율을 향상시키고자 한다. 대상 및 방법 : 2004년 1월에서 2005년 1월까지 Knee Pain이 있는 환자로 본원의 류마티스내과에 내원한 220명(남:38명, 여:182명, 평균연령:57.3세)의 환자를 대상으로 표준인 AP-WB와 MTP검사를 병행하여 실시하였다. MTP검사는 20명의 모의환자로 발의 위치를 확인하며 슬개골이 슬관절부 정중앙에 위치하고, 관절강의 좌우대칭이 일치하도록 하였다. 관절간격과 신생골을 0(나쁨), 1(보통), 2(좋음), 3(아주좋음)점으로 구분하여 정형외과의사 3명, 류마티스 내과의사 2명, 방사선과 전문의 3명, 방사선사 5명이 PACS 모니터에서 영상을 Blind test하였다. 장비는 PHILIPS(Buckey Diagnostic-TH)를 사용하였고, 100 cm거리에서, 60 Kv, 8 mAs로 설정하였다. 결 과 : 위 방법으로 다음과 같은 결과를 얻을 수 있었다. 1. MTP 촬영법 : 발을 바깥쪽으로 $15^{\circ}$회전하고 무릎을 구부려 카세트 면에 대면 슬개골이 슬관절부의 정중앙에 위치하였고,관절강의 정렬에 따른 좌우대칭이 일치하였다. 2. 관절간격 점수 : AP-WB 촬영법; $1.32{\pm}0.050$, MTP 촬영법; $2.51{\pm}0.046$ 3. 신생골 점수 : AP-WB 촬영법; $2.14{\pm}0.054$, MTP 촬영법; $2.10{\pm}0.054$ 결론 및 고찰 : 이번 연구는 임상적인 판독 방법으로 관절간격과 신생골에 따른 점수를 비교 했을 때, MTP 촬영법이 가장 중요한 관절간격을 영상으로 표출하는데 있어서 기존의 AP-WB 촬영법보다 훨씬 더 우세하다는 결론을 갖게 되었다. 따라서 향후 골관절염 환자의 진단율을 향상시키는 데는 MTP촬영법이 유용할 것으로 사료된다.

Purpose - This study attempts to extend the research in responsible luxury by identifying contexts where Corporate Social Responsibility (CSR) can promote luxury brands' evaluation. It contributes to the literature on consumer responses to CSR, and to responsible luxury in particular and demonstrates how dispositional consensus and luxury-CSR information of luxury brands affects consumers' evaluation of brand. Research design, data, and methodology - An experiment was conducted to test the relationship between brand evaluation and responsible luxury brands' CSR information using collected data through a survey in a large university of South Korea. Study conditions were manipulated with various product types to analyze the relationship in different product domains. Results - When consensus regarding sincere and altruistic motive of companies for CSR activity is high, the perceived fit between luxury brand and the type of CSR has no effect on brand evaluation. But, in case of lower consensus regarding the benevolent company motives, higher fit enhances evaluation than lower fit. Conclusions - In using consensus as a guiding factor to choose the type of charity with favorably view, the level of irrespective fit can help luxury firms to enjoy the benefits of better image. In case of low consensus donating to charities that are closely related to the brands' product or area of business seems to be fruitful.
