This study is aimed to look into the craftsmanship non-educated constructors in Korean-style secondary stations(Gong-So) of Naepo region which is located in the northwestern Chungcheongnam-do. Although the area was persecuted as one of three cradles of Korean Catholicism, Catholic activities flourished there. The 13 cases of Korean-style secondary stations were selected through a survey report list about modern cultural assets of Chungcheongnam-do published in december 2004. This study examined the methods of plan layout and framework of Gong-So to look into craftsmanship of non-educated constructors, the results are as follows; The methods of plan layout are divided into three types according to existence and arrangement of inner column(Nae-Ju); 'Layout with Nae-Ju' is considered as the primary form of Korean-style Gong-So with using regular Nae-Ju. 'Layout with the different position of the center between Nae-Ju and exterior column(Oe-Ju)' and 'layout without Nae-Ju' is appeared in Korean-style Gong-So which is important to assembly and alter function. The methods of framework are appeared variously according to different plan layout for securing worship space. The unusal beam(Chung-Ryang) is used to solve different spans of altar and narthex. When space was formed widely without Nae-Ju, diagonal members and M letter type rafters are used, they are influenced by the technique of western wooden roof truss.

This paper presents a current mode integrated control technique (CM-ICT) using a modified voltage space vector modulation (MSVM) for Z-source inverter (ZSI) fed induction motor drives. MSVM provides a better DC voltage boost in the dc-link, a wide range of AC output voltage controllability and a better line harmonic profile. In a voltage mode ICT (VM-ICT), the outer voltage feedback loop alone is designed and it enforces the desired line voltage to the motor drive. An integrated control technique (ICT), with an inner current feedback loop is proposed in this paper for the purpose of line current limiting and soft operation of the drive. The current command generated by the PI controller and limiter in the outer voltage feedback loop, is compared with the actual line current, and the error is processed through the PI controller and a limiter. This limiter ensures that, the voltage control signal to the Z-source inverter is constrained to a safe level. The rise and fall of the control signal voltage are made to be gradual, so as to protect the induction motor drive and the Z-source inverter from transients. The single stage controller arrangement of the proposed CM-ICT offers easier compensation. Analysis, Matlab/Simulink simulations, and experimental results have been presented to validate the proposed technique.

The purpose of this study is to figure out the trends of the community facilities patterns in the designated apartments through the method of analyzing a case of a community housing yet to be open to its tenants. The thesis is based on document research and analysis of apartments categorized into five different groupings all in a status of being a prospective dwelling. The conclusion of the case study results as follows. Firstly, the distribution of a plan is either centrifugal or widespread. Secondly, the elevation plan contains its facilities in the basements or low-rise floors. Thirdly, sports facilities such as an indoor driving range, a fitness club and a GX-room and a open square on the outer space were unifiably common to all five groupings. In conclusion, in light of the facility patterns shown in the five extracted groupings of apartments, it seems that it will be difficult for all residents to benefit from the public facilities because the facilities are perceived as being limited to only a specific tower which hampers the improvement of the quality of life of the rest of the tenants and dampens an active social gatherings. Therefore, the public facilities must be planned and constructed to meet the satisfaction of the residents in whole, in place of being a commercially lucrative space.

The structural design of oil tankers and bulk carriers should be performed based on the Common Structural Rules(CSR) which were recently established by the International Association Classification Societies(IACS). At first, in the structural design viewpoint, the scantling and hullweight based on the CSR should be compared with those of existing rules, and then a minimum weight/cost design should be performed by considering the variation of the number of web and the material property. In this study, the optimum web space and material property will be proposed by performing a minimum weight/cost design of a large oil tanker, and the results will be compared with those of existing ship. The longitudinal members are determined by SeaTrust-Holdan developed by the Korean Register of Shipping(KR), and the transverse members are determined by NASTRAN and PULS.

Due to the development of technology, urbanization, industrialization, etd. at modern times, even the individual view of value has changed in variety. That means the change of each consumcer's life-style and even that of propensity to consume. In that regard, the modern, commercial space became to be increasingly included to specialization and complication. Such specialization and complication of the commercial space can be thought to be a positive response of enterprises to satisfy the needs or desire of consumers who become diversified. In this study, some new models in the method of the planning and designing of the S.I.P(Shop Identity Program). intended to research into as follows ; - As the background of the advent of the multi-used shopping complex, changes in consumer life-style and propensity to consume according to social and economical changes were intended to be studied through various statistical data literature. - For the study of the characteristics, constituent conditions, and planning operation of the future multi used shopping complex in the marketing aspect of enterprises, it was intended to study centered on the theory of consumer behavior and that of retail marketing. - In the process of the spatial design of the multi-used shopping complex, it was tried that a designing process to materialize a target of the discrimination and orderly arrangement of stores be progressed. In the process of materializing a target based on both corporate image and 'brand' image in designing.

The purpose of this study is to analyze the unique characteristics of the vernacular house of Ulleung-Do(island), which shows a different residential culture from the main land. For this purpose, this study examined the characteristics of the location, spatial arrangement, and floor-plan of the house and also tried to understand how these basic elements were changed and why these changes were occurred. The result of this study is as follows: First, the house was located on the mountain area and was oriented toward the various bearings. Second, the house usually did not have annexes and most residential space was installed on a main building. Third, the floor-plan of the house was developed from a basic two-Kan (with single row) house type in a early settlement period to three-Kan, four-Kan, and five-Kan house types in later periods. While the development of house type proceeded. the main building was functioned as a complex space for both residential and storage purposes. Some houses were gradually developed into a middle and upper-class house shape by installing annexes. The change of the floor-plan and the house size was the result of self-sustained living culture influenced by the natural environment of the island and of changes of residential conditions as well.

As ongoing construction of a new municipal government building leads to the destruction of the interior of the Kyungsung Municipal Government Building(currentlySeoul Metropolitan City Hall) despite its enormous historic value, this study aims to identify the unique features of spatial composition and interior design of the Kyungsung Municipal Government Building, which is widely known as a typical example of public architecture of the 1920s. The primary goal is to perform a systemic arrangement of its interior data and define the modern historic implications of its interior design, thereby laying the foundation for a compilation of the history of modern interior design. From a historical perspective, the Kyungsung Municipal Government Building-an explicit symbol of Japanese colonial supremacy-has served as the administrative hub of a hugecity for 19 years during the Japanese colonial rule and for 64 years following Korea's independence from Japan. From the perspective of architectural history, it also represents modern transitional buildingsin their shift from historicism into modernism, as manifested by its reasonable placement of interior space matching well with topographical form, easy access by citizens, open office space, and, excluding decoration, a simple and non-authoritarian exterior. Its interior design style follows Western historicist architecture, whereasits simple interior decoration embodies expressive characteristics of pragmatic simplicity. Such elements are notably found in the Grand Central Hall, the Municipal Head's Reception Room, and the Grand Conference Room.
