The present study aims to develop measures to enhance user service at Chungnam Representative Library by establishing Chungnam Representative Library Operation Master Plan. To this end, I conducted a literature review, analysis of services of other representative libraries, and a survey. The study results suggested six measures for user service enhancement. The first measure is space-specific programs, such as children's materials room, general materials room, electronic materials room, auditorium, multipurpose room, outdoor stage, exhibition room, and book café. The second measure is the services specific user types, such as children, adolescents, adults, the disabled, and multicultural families. The third measure is information service specific for information type, such as print material service and digital material service. The fourth measure is the service for the Information-Poor including the expansion of mobile library service, the service for information users in special environment, and the development of mobile library rules. Fifth measure is information service for Chungcheongnam-do residents, such as Baekje Studies specialized service that incorporates local characteristics, specialized information service for Chungcheong Studies and local materials, and information service for administrative and policy materials. The last measure is the measure to secure initial users and early stage service enhancement.

To analyze the space features of small-sized detached houses, this study has compared the floor plan types of detached houses and apartments. Currently small-sized detached houses are popular in Korea. The comparative analysis was focused on common residential patterns and the apartment plan. The results of space syntax were summarized as follows: four types of apartments and twelve types of small-sized detached houses were deduced by the relative spatial depth analysis. Among the sixty-seven house samples, only two of them showed the same pattern as those of apartments, which showed that each room of detached houses had distinct difference with those of apartments. According to the integration and control analysis, each space of apartments showed difference within narrow range, while the space of detached housed showed difference within wide range. In addition, the detached houses showed distinct relations between the center of space and the surroundings, and there are distinct differences between the easier layouts for access rooms and difficult ones. Moreover, the living rooms of detached houses somewhat exist under the low integration condition, and they cannot be standardized in the center of house, which are different with those of apartments. The master bedrooms of detached houses exit at the surrounding space same as those of apartments. Nevertheless the toilet is in the master bedroom which made its control lower than those of apartments.

This study compares the space depth and layout of a modern apartment floor plan (MAFP) and the standard floor plan of traditional Korean houses (STKHs), which has preserved the traditional beauty of Korea. Space Syntax was applied to compare the MAFP and STKH. The space within MAFP was more divided into many spaces than the STKH. In both types of floor plans, the living room space had the highest degree of integration and was used for central functions in the each floor plan. The STKH and the space in the MAFP have more segregated space than integrated space. In the STKH, the master bedroom and other rooms were found to be segregated space. However, the master bedroom of the MAFP was highly integrated space. The function of the thet maru has been greatly reduced in the STKH, and the numaru was classified as a highly segregated space. The evacuation space was the most segregated space in the MAFP. The STKH has been adapted and changed according to the trends of the times, and the MAFP reflects our traditional living habits.

Smart museums based on the growth of online exhibition can be seen as in line with the movement of the 4th Industrial Revolution. By combining art and technologies, they enable viewers to experience culture and art. This study examined the cases of the Dunhuang Museum, the Palace Museum, and the China Arts and Crafts Master Museum to assess or identify how China is leading by accepting the technology of the fourth industry and applying the technology. In common, Chinese smart museums are widely used for collecting enviromental data, establishing integrated digital applications, and preserving collections, services, management, and exhibitions through VR, and AR. Through the case of the Chinese Smart Museum, this study identified the online exhibition as a space that exists in another dimension rather than an image replica with excellent operational utility. Therefore, online exhibitions are the best medium to expand the space, and viewers can explorethe museum's exhibition room and engage with all the contents of the museum without visiting the museum in person. Through the online exhibition of smart museums, visitors and viewers can be transformed into more active cultural consumers and develop collective capabilities.

The validity of 'modified overlay model' to describe the cyclic behavior of annealed 316L stainless steel at room temperature was investigated. Material parameters(~f$_{i}$, m$_{i}$b, η, E) fur the model were obtained through constant strain amplitude test. The strain amplitude dependency of elastic limit and cyclic hardening, which were the characteristics of this model, were considered. Eight subelements were used to describe the nonlinearity of the hysteresis loops. The calculated hysteresis curve in each condition (0.5％, 0.7％, 0.9％ train amplitude test) was very close to the experimental one. Two tests, incremental step test and 5-step test, ere performed to check the validity of 'modified overlay model'. The elastic limit was saturated to the one of the highest strain amplitudes of the block in the incremental step test, so it seemed to be Masing material at the stabilized block. Cyclic hardening was successfully described in the increasing sequence of the strain amplitude in 5-step test. But, the slight cyclic softening followed by higher strain amplitude would not be able to simulate by'modified overlay model'. However, the discrepancy induced was very small between the calculated hystereses and the experimental ones. In conclusion,'Modified overlay model'was proved to be appropriate in strain range of 0.35％~ 1.0％..0％.

The purpose of this study is to design and develop the circuit of the dual mode syringe pump. Syringe pump is used in intensive care unit, delivery room, pediatric room, operating theater and other fields of hospital at present. Normally the syringe pump delivers one medicine in one case, but in case of intensive care unit, it is necessary to deliver more than two kinds of medicines at a time. Therefore we have designed dual mode syringe pump. We used RISC type microcontroller, PIC17C44 as master controller, and PIC16C73 as slave cpu using for the low power consumption. The performance of system is evaluated by analysis of the linearity and accuracy which is the most important factors in application. While the proposed system shows a acceptable linearity and accuracy, a further research about reducing the errorr should be done.

Recent decreased number of family members have caused at least one spare room which is not used as a bedroom in an apartment house. In addition, people who need an apartment house cannot be satisfied with the typical unit plan any more, and rather request more various types of living space. Based on this kind of housing needs trend, we would like to analyze and classify dwelling unit planning methods which may create particular purpose extra rooms to satisfy their unique needs and to give characteristics and individualities by means of study on various cases. As a result of this study, we could find the following planning methods which can produce extra rooms : 1) Utilization of optional plan between living room and adjacent bedrooms, 2) Utilization of optional plan on master bedroom zone, 3) Insertion of transitional space and Utilization of spare space, 4) Insertion of a space for housewives near a kitchen, 5) Positive utilization of a balcony space. This study is also trying to show many unit plan cases of which planning methods can be applied in other cases.
