With the rapid progress of the aging society in Korea, the silver generation is emerging as another class of users in the new population structure. This is a social issue to be dealt with, and the effect of such a change is being observed dearly in the design area. In addition, there are increasing demands for consideration of minor groups of users including the elderly, the disabled, the left-handed, children and pregnant women and nursing mothers, who have been treated as the weak. Such a human-centered idea may be the manifestation of the recovery of humanity and the self-realization of human beings through experiences and reflections of the industrial society of the past. The present study examined the tendency of design standardization centering on universal design, which has emerged in response to user-centered social needs, and suggested general considerations for the necessity of introducing such standards. These days the meanings of standardization are not limited to quality, performance, safety and economic aspect. Standardization is required to consider the diversity and the welfare of human beings. In addition, one of the important functions of standardization is to provide designers with important clues and guidelines for designing. In reality, however, standardization has been rejected by the circle of design for the reason that it deters free creation, so research on the introduction of standardization has been at standstill. As ISO/IEC Guide71 was published in November 2001, based on which, the Korea Standards Association established KS A ISO/IEC Guide71 without changing its contents. In companies' manufacturing activities, the progress of standardization in connection to universal design is growing more important. However, usefulness and interchangeability for the absolute majority resulting from standardization are incomparable. Lastly, the realization of universal design requires human-centered design mind, based on users' experiences and needs, the characteristics of the human bodies and inconvenient elements rather than standards for the sake of standardization.

The purpose of this study is to check effects on the awareness of parents supporting in their self retirement preparation of the baby boomer generations who have faced relatively bad situation in this era considering the reality of great changes brought in the parents supporting spirit which was regarded as family and individual responsibility due to the rapid industrialization and urbanization. In the result of this study, some points such as religious, living status and monthly average earning show meaningful result and also all of the colligation in the retirement preparation standard concerning economic living life, health life, leisure time, family life, dwelling life and leisure life shows most significance probability of .001(*p<0.05) and retirement preparation standard relative to economic life indicates significance probability of .005(*p<0.05). Eventually this result shows that the higher people have retirement standard, the higher parents supporting sprit they have. So I would like to suggest some policy advices on the basis of this study. First stable supporting policy on their dwelling life should be assisted by differential methods, secondly social programs aid for leisure life through social activities like volunteer work are required, further more national based policy supports for youngsters are considered in order to reduce economic daily life on their economic activities.

The FPDs(Flat Panel Displays) such as LCD(Liquid Crystal Display) and PDP(Plasma Display Panel) and OLED(Organic Light Emitting Diode), recently, have been substituted for CRT(Cathode Ray Tube) displays because they have a convex surface, small volume, light weight and lower electric power consumption. The productivity of FPDs is greatly dependent on the area of thin glass panel with 0.6 - 0.8mm thickness because FPDs are manufactured by cutting a large-scaled thin glass panel with patterns to the required product dimensions. So FPD's industries are trying to increase the area of thin glass panel. For example, the thin glass panel size of the 8th generation is 2,200mm in width, 2,600mm in length and 0.7mm in thickness. The air flows both in the thin glass panel and in the porous PE-plate surface were modeled and analyzed, from which a working condition was estimated. The thin glass panel on the porous PE-plate surface with self-lubricating characteristics was investigated and compared with that on the square duct floating bar surface with many holes of 1mm diameter when the thin glass panel contacts the floating bar surface due to malfunction of electric power supply.

This research is to explore food waste management across local governments. In particular, pubic administration on food waste, food waste management (from generation to disposal) and civil complaints in jurisdiction are examined. In doing so, a self-administered questionnaire survey was conducted among civil officers in charge of food waste management, and all the collected responses were statistically analyzed. The main results were as follows: public spending on food waste management was a little larger in metropolises than in provincial cities, and the largest food waste source was identified as households (in housing). While regular collection of food waste by trucks was the most common transport method adopted by local governments, resource recovery for compost/fertilizer production was widely used. Also, most of the respondents agreed that the current approach to food waste handling practices are necessarily replaced with more advanced technology converting waste into energy or fuel. Further, it's found that the civil complaints on food waste management were largely categorized into 3 groups - food waste handling, civil service and food waste retrieval. Therefore, the findings indicate that the development and application of no-food waste or waste-to-resource systems are effective in housing estates where large amount of food waste is generated and eliminated.

Archives have historical and academic values. That is why the study of preservation conditions and the environment for the effective management of various records progress. However, materials such as paper and adhesives will inevitably cause biological damages. These damages spread into the inner side of archives, which would make it impossible to recover. For example, archival records from Malaysia and Oman are easily exposed to biological damage because of these countries' hot and humid climate. As such, once records are damaged, disinfection operations are customary in these areas. Methyl bromide (MeBr) and ethylene oxide (EtO) were used in the disinfection process as they showed good insecticidal effect. However their antibacterial effect are negligible. As such, the need for an environmental-friendly fumigator was evident. An environmental-friendly fumigator is designed to improve storage stability. Such equipment is expected to contribute to prevention of damages to cultural heritages through its use of vaporization technology, maintenance of a disinfection space (chamber), and self-generation of nitrogen.

The IEEE standard 1149.1, which was proposed to increase the observability and the controllability in I/O pins, makes it possible the board level testing. In the boundary-scan environments, many shift operations are required due to their serial nature. This increases the test application time and the test application costs. To reduce the test application time, the method based on the parallel opereational multiple scan paths was proposed, but this requires the additional I/O pins and the internal wires. Moreover, it is difficult to make the designs in conformity to the IEEE standard 1149.1 since the standard does not support the parallel operation of data shifts on the scan paths. In this paper, the multiple scan path access algorithm which controls two scan paths simultaneously with one test bus is proposed. Based on the new algorithm, the new algorithm, the new board level BIST architecture which has a relatively small area overhead is developed. The new BIST architecture can reduce the test application time since it can shift the test patterns and the test responses of two scan paths at a time. In addition, it can reduce the costs for the test pattern generation and the test response analysis.

The purpose of this study is to develop and evaluate the effect of a teaching-learning plan for teaching about Hanbok to high school students. Results of this study are as follows. First, learning themes in the teaching-learning plan were selected so that the learning objectives could be achieved by gradually advancing from understanding to exploring and finally practicing. Teaching and learning activities for conceptual classes focused on students' exploration and thinking processes. For Making project, students were asked to complete a group artwork using characteristics and images of Hanbok while applying creative thinking and collaboration. Second, the teaching-learning plan was evaluated by comparing students' pre- and post-test scores of knowledge in, perception of, and attitude toward Hanbok; and by analyzing students' journal of reflection and teacher's observation diary. The mean scores of high school student' knowledge, perception and attitude of the post-test were significantly higher than those of pre-test. The content analysis showed that students gained extensive knowledge toward Hanbok and found new values through their classes. Making practices with generation of creative ideas and collaboration has been effective in training a self-directed and a creative learner.

The purpose of this study is to consider ontology theory and get to forge design and implementation of ontology-based access system which is support to the nutrition and food guide tower of Home Economics textbooks in middle school in order to offer the way of effective learning performance. It offers a model by establishing a nutrition and food guide tower access system based on Protege-2000 framework. This system is on the basis of XML, and it makes possible to work with semantic web, a next generation internet technology, and provides a meaning structure that can be shared in the field of nutrition in order to build up the fundament of knowledge an information system for the mutual operations. A learner can systemize the knowledge through a self-information access and an instructor can also check out the degree of learner's learning-accomplishment and interests, directly putting the access system into the teaching and learning process. In addition, it is supposed that the learner can maintain a balance and healthy life by internalizing his or her knowledge throughout ontology not only in a teaching and learning process but also in a daily life.

This study focuses on the methodology of an ecological interpretation of Korean traditional landscapes through both life-oriented philosophy and traditional Korean philosophy which are similar to ecology. Also, useful tools for discovering an ecological technique of formation based on the ecological thoughts in ancestors' life are shown. Ecological key words as interpretative tools on the traditional landscape replaced ecological concepts in Korean culture and landscape. There are 'Bonsung(本性; the original nature)', 'Chungjeol(中絶; moderation)', 'Hyoyul(效率; efficiency)', 'Sangsaeng(相生; symbiosis)', 'Jasaeng(自生; self-generation)', 'Chunghwa(中和; neutralization)', 'Bangtong(旁通; communication)', and 'Byuntong(變通; variableness)'. For the case study, the concepts of 'spatial structure', 'constructive elements in the traditional gardens', and 'structural elements in the dwelling houses' were extracted from $\ulcorner$Imwonkyeongjeji$\lrcorner$ as an interpretative subject. As a result, Jeongon house, Jongtaek of Choi's family(the first incoming resident) showed us an ecological technique of formation by interpretation on the composing elements. Namely, they are natural dwelling houses in harmony with natural conditions and delicate relational styles. Five kinds of ecological characteristics were exposed. They are: 1. land use method following natural features('本性' '相生' '中和'), 2. physical and spatial elements in a body with nature('中絶' '相生' '中和'), 3. sustainable circulation system by recycling limited resources('效率' '自生' '旁通'), 4. use of natural materials based on the regional climate ('中絶' '效率' '自生') and 5. plane and structural decision by microclimate('效率' '自生' '變通'). Consequently, the dwelling houses and their traditional gardens aimed at the consuming space of the efficient resources by utilizing and circulating natural energy more than different types of the traditional spaces.

ZnO has a very large exciton binding energy (60 meV) as well as thermal and chemical stability, which are expected to allow efficient excitonic emission, even at room temperature. ZnO based electronic devices have attracted increasing interest as the backplanes for applications in the next-generation displays, such as active-matrix liquid crystal displays (AMLCDs) and active-matrix organic light emitting diodes (AMOLEDs), and in solid state lighting systems as a substitution for GaN based light emitting diodes (LEDs). Most of these electronic devices employ the electrical behavior of n-type semiconducting active oxides due to the difficulty in obtaining a p-type film with long-term stability and high performance. p-type ZnO films can be produced by substituting group V elements (N, P, and As) for the O sites or group I elements (Li, Na, and K) for Zn sites. However, the achievement of p-type ZnO is a difficult task due to self-compensation induced from intrinsic donor defects, such as O vacancies (Vo) and Zn interstitials ($Zn_i$), or an unintentional extrinsic donor such as H. Phosphorus (P) doped ZnO thin films were grown on c-sapphire substrates by radio frequency magnetron sputtering with various Ar/ $O_2$ gas ratios. Control of the electrical types in the P-doped ZnO films was achieved by varying the gas ratio with out post-annealing. The P-doped ZnO films grown at a Ar/ $O_2$ ratio of 3/1 showed p-type conductivity with a hole concentration and hole mobility of $10^{-17}cm^{-3}$ and $2.5cm^2/V{\cdot}s$, respectively. X-ray diffraction showed that the ZnO (0002) peak shifted to lower angle due to the positioning of $p^{3-}$ ions with a smaller ionic radius in the $O^{2-}$ sites. This indicates that a p-type mechanism was due to the substitutional Po. The low-temperature photoluminescence of the p-type ZnO films showed p-type related neutral acceptor-bound exciton emission. The p-ZnO/n-Si heterojunction LEO showed typical rectification behavior, which confirmed the p-type characteristics of the ZnO films in the as-deposited status, despite the deep-level related electroluminescence emission.
