The purpose of this study is suggesting the direction for improving web accessibility by analyzing the state of abiding by the web accessibility by the centers for teaching and learning support at the education offices in cities and provinces which provide the learning and teaching materials to the K-12 members and the interested people. For this aim, nine centers for teaching and learning support were evaluated. The primary manual evaluation by two experts and the evaluation by 18 users were conducted. The users were comprised of hearing-impaired people, visually-impaired people, brain-disabled people, the elderly, various browser users, and a variety of operating system users. As a result of the analysis, not a single center for teaching and learning support had conformed to web accessibility in the expert evaluation and the user evaluation. As a result of the expert evaluation, the errors regarding web design improvement, HTML source error correction, and provision of alternative measures for the disabled were found. This study is meaningful in the sense that it provided various discussions with regard to the direction of the future web accessibility evaluation based on the improved web accessibility evaluation method.

Quantitative structure-activity relationship (QSAR) analysis for recently synthesized imidazole-(benz)azole and imidazole - piperazine derivatives was studied for their anticancer activities against breast (MCF-7) cell lines. The statistically significant 2D-QSAR models ($r^2=0.8901$; $q^2=0.8130$; F test = 36.4635; $r^2$ se = 0.1696; $q^2$ se = 0.12212; pred_$r^2=0.4229$; pred_$r^2$ se = 0.4606 and $r^2=0.8763$; $q^2=0.7617$; F test = 31.8737; $r^2$ se = 0.1951; $q^2$ se = 0.2708; pred_$r^2=0.4386$; pred_$r^2$ se = 0.3950) were developed using molecular design suite (VLifeMDS 4.2). The study was performed with 18 compounds (data set) using random selection and manual selection methods used for the division of the data set into training and test set. Multiple linear regression (MLR) methodology with stepwise (SW) forward-backward variable selection method was used for building the QSAR models. The results of the 2D-QSAR models were further compared with 3D-QSAR models generated by kNN-MFA, (k-Nearest Neighbor Molecular Field Analysis) investigating the substitutional requirements for the favorable anticancer activity. The results derived may be useful in further designing novel imidazole-(benz)azole and imidazole-piperazine derivatives against breast (MCF-7) cell lines prior to synthesis.

With the increase in private and community archives to record various different shapes and forms of societies, the establishment of archives for social minorities has heightened. In line with these changes, this study analyzed the Korean queer archives "Queerarch," which focus on records and archives on sexual minorities. This study examined the current status of the archives of Queerarch, and grasped the characteristics of the queer archives and the problems of archival description elements. The current archival description elements used in Queerarch do not fully reflect the characteristics of the queer archives and the multilayer description method. To solve these problems, this study proposed a metadata schema that includes archival description elements that are based on archival description standards such as the General International Standard Archival Description (ISAD (G)), Manual of Archival Description (MAD), Rules for Archival Description (RAD), and others.

This study was performed by the literature review on housing of the aged in Korea with social constructionism perspective. This kind of research may be utilized as a theoretical framework for performance of any systems of housing for the aged. In terms of structural context, the value of conventional custom of filial piety thoughts and duty for family are being collapsed, which nay be suitable to the change of society, should be considered for positive acceptance of changes in ideology. In terms of institutional context, a method to grope for housing for the aged should be established through amicable cooperation between organizations of legalization concerned. In terms of organizational context, there is no organization that exclusively concern housing for the aged until now, thus, development of concrete manual is required for jobs of service in current department of policy for the aged. In terms of operational context, the service may include the understanding of characteristics of the aged and design of housing may also change the service of administration, and as cooperation in the local community care systems may change the service to the aged in the field. Connection of these services and operation of these organizations nay be required in the field to manage housing. Finally in terms of intersubjective context, as the form and method of housing management service is important, with understanding of the social meaning and importance on the role of manager.

To complete an image, it is needed to go through the process to capture the actual actor's motion and compose it with virtual environment. Due to the excessive cost for production or lack of post-processing technology, however, it is mostly conducted by manual labor. The actor plays his role depending on his own imagination at the virtual chromakey studio, and at that time, he has to move considering the possible collision with or reaction to an object that does not exist. And in the process of composition applying CG, when the actor's motion does not go with the virtual environment, the original image may have to be discarded and it is necessary to remake the film. The current study suggested and realized depth-based real-time 3D virtual image composition system to reduce the ratio of remaking the film, shorten the production time, and lower the production cost. As it is possible to figure out the mutual collision or reaction by composing the virtual background, 3D model, and the actual actor in real time at the site of filming, the actor's wrong position or acting can be corrected right there instantly.

The structures built under the groundwater level are affected by the buoyancy force, which is hydrostatic pressure in the up direction. Recently, buoyancy-resistant anchor method has been applied in many cases of the construction of the important structure of large size, which is built under the groundwater level so that it takes high uplift pressure. Even if the construction cost of the method is very high, it surely increases the safety rate. However, the diagnosis of the performance of the buoyancy-resistant permanent anchor and the investigation of resistance mechanism are still insufficient. Especially, the long-term behavior of the anchor has not been studied well due to the difficulty in observation procedure. The contribution of this paper is the establishment of reasonable design methodology. We have measured anchor axial forces for 10 years after the construction, by using an automated measurement and a manual measurement by establishing a load cell in anchor head. Through the data collected from the measurements, we analyze the construction-step behavior of the anchor according to the self-weight variation of the building and the long-term behavior (i.e. movement within 10 years after the construction) of the anchor according to the passage of time.

Although the usage of gas as one of the most economical energy source is ever expanding, numerous gas accidents occur as a result of negligence in safety management. The main reason behind such accident is that the current safety control system relies heavily on the manual control mechanism. This paper designed and developed a prototype of a computerized gas safety control system that automates such critical functions as the alarm sensing and the valve control. Since the system is connected through a digital network, the control can be performed remotely. Most importantly, the accidental risk or damage can be greatly reduced since the system monitors and reacts actively to gas leakage in real time.

Purpose: Considering the proportion of the population such as the elderly, pregnant women, infants companion and constantly increasing foreign tourists, there is a high need for implementing an environment without barriers. In terms of policy and institutional aspects, Jeju Special Self-Governing Province is striving to create an environment without barriers and to promote the safety and convenience of Vulnerable Pedestrians. But it is not enough to create a viable barrier-free environment. Methods: Method of this research is to analyze the general population status and installed facilities status for the disabled in Jeju. And analysis of policy research needs and level of barrier-free. By applying the barrier-free environment certification standards should conduct an assessment of the level of the current public office buildings in Jeju. It presents the environmental improvement of public office buildings for barrier-free environment. Result: Barrier-free environment status of the five public office buildings research surveyed all buildings have shown low levels of installed facilities for the disabled. In particular, it was analyzed that represents a very low level in the intermediate facilities and other facilities. The development of a specific installation manual for the facilities for the disabled is required to improve public office buildings. And barrier-free criteria need to reflect on the implementation of regulations. Implications: Through continuous research to analyze the barrier-free level and problems of public office buildings, it will be made to improve the comprehensive and reasonable alternative.
