Purpose of this study is studying direction that change of design by development of new digital technology. And with new technology, find direction of architectural design. Digital technology for architectural design demonstrates hightechnology or is not limit. Must recognize change for our idea and necessity. We can know change in relation of photography and impressionism. Idea and hitting on a thought which is arts by new technology changed. Finally, we must develop techniques of design on the basis of technology and look for possibility of new expression. Digital medium expands communication with designer and customer because there is special quality of nonlinearity, interactivity and audiovisuality unlike old medium. Digital medium can take advantage of techniques of new design. Can construct R&D and database of design and improve quality of design. Designer must master use skill to take advantage of digital technology in design. Because quality of design becomes different according to degree that use. Also, developer of digital technology must supply design tool such as previous design method. Creativity that architectural design that allow fetters in digital technology can understand design in new viewpoint is required. Architectural design may be magnified by architectural design that allow fetters in multimedia. We may see experience between new time and space of architectural design and reappearance space reappeared in cyberspace. Architect is going to run role as developer of culture. Value and technology of digital design may offer more more possibility and an opportunity since Intustrial-Revolution.

The 19th CPC National Congress has a key historical significance in the development of China's constitution. It will also play a decisive role in the history of the seventy years'constitutional change in New China. XiJinping's new socialist thought with Chinese characteristics established in the report of 19th CPC National Congress will be written in the preface of the March 2018 National People's Congress's constitutional amendment. The fifth revision of 1982 Constitution will touch on many issues such as the leadership of the CPC into the constitution, the abolition of the tenure of the president, the constitutional oath system, and the reform of the national supervisory system. In addition, the constitutionality review system, the establishment of the National Security Council, the constitutional status of socialist public property and private property and the adjustment of major economic system has become a hot topic in the theory field. In the history node towards a socialist country ruled by law, the theory and practice of the China indeed have the academic ideas, value position and path model differences, which will delay the Chinese constitutional development, but also is the necessary pain in the process of moving towards the rule of law in China. Indeed, how to the development and where to go in the future of Chinese constitutionalism itself has sample value, which deserves rational attention and in-depth inquiry from Chinese and Western academics.

This paper describes the development of a surface acoustic wave gas sensor that is designed to detect volatile gas by monitering phase change of output signal as a function of time. The sensor consists of SAW oscillators with a center frequency of 100 MHz fabricated on $128^{\circ}$ Y-Z $LiNbO_{3}$ substrates. Experimental results, which show the phase change of output signal under the absorption of volatile gas onto sensors, are presented. The proposed sensor has the properties of high sensitivity compare to the conventional SAW gas sensor and chemical selectivity. Thus, it is thought these results are applicable for use in sensor array of an high performance electronic nose system.

Purpose: The purpose of this study was to investigate the effects of group art therapy on old adults' powerlessness, loneliness. depression and self-image (for 55-year old or older people). Method: An experimental group of 10 persons were given group art therapy for 1 hour per week for 8 weeks. Results: The result of this study showed that group art therapy is effective in decreasing older adults' powerlessness (p<0.05) and their loneliness and depression (p<0.05). However, there was no significant difference in the score of loneliness (p>0.05). A tree test was executed to analyze self-image change. and the result of the tree test showed a significant change in the tree shape. which mean a significant positive change in self-image. Conclusions: The scores of older adults' powerlessness, loneliness and depression were lowered by the group art therapy. Therefore it is thought that group art therapy program was an effective intervention for improving older adults' quality of life. Thus, this study suggests to apply group art therapy as a supportive nursing intervention in order to manage powerlessness, loneliness, depression and self-image in old low-income adults.

A unique technique to estimate the magnitude or contribution ratio of each stage backlash in a system with a two-stage gear reducer is proposed. The concept to estimate the magnitude or contribution ratio of each stage backlash is based on the change of frequency response characteristic, in particular, the change of anti-resonant frequency and resonant frequency, due to the change of each stage backlash magnitude, even though the total backlash magnitude of a system with a two-stage gear reducer is constant. The validity of the technique is verified in a seeker gimbal and satisfactory results are obtained. It is thought that the diagnosis and maintenance of the manufacturing machines and systems with two-stage gear reducers will become more efficient and economical by virtue of the proposed technique.

Due to the problems of global warming, the frequency of meteorological extremes such as droughts, floods and the annual rainfall amount are suddenly increasing. Even though the increase of greenhouse gases, for example, is thought to be the main factor for global warming, its impact on global climate has not yet been revealed clearly in rather quantitative manners. Therefore, tile objective of this study is to inquire the change of precipitation condition due to climate change by global warming. In brief, this study want to see its assumption if rainfall quantile estimates are really changing. In order to analyze the temporal change, the rainfall quantile estimates at the Seoul rain gauge stations are estimated for the 21-year data period being moved from 1908 to 2002 with 1-year lag. The main objective of this study is to analyze the variability of rainfall quantile estimates using four methods. Next, The changes in confidence interval of rainfall quantile are evaluated by increasing the data period. It has been found that confidence interval of rainfall quantile estimates is reduced as the data period increases. When the hydraulic structures are to be designed, it is important to select the data size and to re-estimate the flood prevention capacity in existing river systems.

For the relationship between conformance cost and the individual elements of non-conformance, an analysis was made of the relationship between inspection cost and training cost and scrap cost. As a result it was explained that there was all a positive correlation between training cost and scrap cost, and between inspection cost and scrap cost. Like this, training and inspection cost and scrap cost have a positive correlation. Judging from the fact that the coefficient of inspection cost is lower than that of training cost in the comparison of the coefficient of each cost, it can be analyzed that the change in scrap cost is influenced by the change in training cost more greatly than the change in inspection cost. If doing so, it can be interpreted that scrap cost and rework cost do not still decrease in spite of increasing in education and training cost and prevention cost. This result may represent the problem as to whether education and training cost is effectively expended for prevention activity. Accordingly, to cope with this situation, it is thought that scrap cost should be cut by establishing the effective prevention measure for causing the increase of scrap cost.

A special concern is paid to the risks with which small-sized water resources systems are confronted in supplying water in the far future. Taking the Gwangdong dam reservoir as a case study, the authors seek to understand demand-side and supply-side disturbances of a reservoir, which, respectively, corresponds to effects of water demand changes on the intake amount and those of climate changes on the inflow amount. In result, it is demonstrated that both disturbances in the next 50 years are almost unpredictable. Yet the projection ranges, thought of as relatively reliable information that models offer, reveal that severity and period of water shortage is very likely to change. It is therefore concluded that water resources management requires more rigorous approaches to overcoming high uncertainties. The methods and models for projecting those disturbances are selected, based on practicality and applicability. Nevertheless, they show a large usefulness, especially in dealing with data shortage and reducing the needs for expensive modeling resources.

The purpose of this study was to seek desirable direction of science teaching and to present meaningful ideas for implementing the science curriculum and teaching materials by measuring the degree of the students' understandings on science and comparing it with those of American students. The researcher comprised 790 primary and middle school students for the study and administered them questionnaires developed by Trowbridge, Bybee, and Sund. The questionnaires were analyzed along with three categories such as science method, science theory, and the achievement of scientists. The researcher used t-test and ANOVA in order to compare the difference of their understandings in accordance with grades and gender, and later compared Korean students' understandings with those of similar aged American students administered by the National Assessment of Educational Progress (NAEP) The research loathed to the overall conclusions as follows; Both primary and middle school students' understandings on science revealed positive and appeared no significant difference in gender. And it is thought that science education was being carried out hopefully to enhancing Korean students' scientific literacy, therefore, science teaching like what is implemented to the classrooms currently should be kept on in future. On the other hand, it is necessary to change primary school children's understandings on attitude and value of scientists while to change middle school students' understandings on scientific processes by experiment. Also primary school children need to understand that scientists are willing to change their ideas when new information becomes known.

목적: Magnetron의 세기를 비대칭으로 한 unbalanced magnetron sputtering 장치를 설계 제작하고 sus304시편 위에 TiN박막을 증착하여 색상과 경도에 관한 연구를 하고자 한다. 방법: 증착된 박막표면의 화학조성을 양적으로 분석하기 위하여 XPS high resolution scan과 curve fitting을 수행하였으며, 박막 표면의 경도를 측정하기 위해 nano indentation 장비를 이용하였다. 결과: 박막 두께가 두꺼워지면 박막의 색상은 처음에는 연한 금색, 시간이 지남에 따라 어두운 금색, 연보라, 남색으로 바뀌었다. 두께에 따른 박막의 색상변화는 박막에$TiO_{x}N_{y}$, $TiO_2$, TiN과 같은 세가지 화합물의 조성변화에 기인함을 알 수 있었으며,$ TiO_{x}N_{y}$의 조성변화가 두께에 따른 색상변화에 가장 큰 영향을 미치는 것을 여겨졌다. 결론: TiN박막의 비커스 경도가 TiN의 일반적인 경도보다 수치가 작은 것은 박막이 TiN, $TiO_2$,$TiO_{x}N_{y}$ 세가지 물질 섞여 있기 때문이라고 여겨지며, 두께에 따른 박막의 경도가 점점 커지다가 줄어드는 것은 두께에 따른 TiN 양과 밀접한 관계가 있음을 알 수 있었다.
