The purpose of this study is to investigate how the 6 entry plans of Seoul Park in Paris were representing the tradition by comparing and reviewing them. Entry plans proposed for Seoul Park revealed different approaches of representing traditional gardens. Through scrutinizing these plans, some similar and different aspects among them could be found out. In order to find out those aspects, the entry plans were analysed and compared into several categories such as design concepts, programs and spatial components. The main concern for analysing the entry plans focused on the issue of are presentation. Representing a Korean garden into Seoul Park depends on the manner of a representation, their objets and media. Objects are related to the contents. The contents can have various themes, events, places beyond the garedn. Meids is related to represent Korean tradition with what implement. The manner of a representation can be divided into three types; a direct representation, an abstract(metaphoric) representation and a destructive representation. We found the characteristics through analysing the entry plans that 1) Korean terrain, Korean thoughts, narrative promenade, past/present/Korea/Seoul, story telling through the Korea traditional fence were used as design concepts. 2) Traditional elements such as a traditional pavilion, fence, madang, hwagye, gate were generally chosen as essential elements for representing the Korean tradition. 3) Direct representations were ore broadly used than abstract and destructive representation as the manner of a representation. and 4) The entry plans show us a variety of possibilities of representing traditional gardens. Abstract and destructive representations of tradition can be found out in th several plans compared with other existing ocean gardens made in foreign countries. In establishing urban parks and ordinary landscapes, those strategies can be alternatives to represent the identity of Korea by reconciling tradition with invention.

This study intends to establish a system to investigate and analyze various impacting factors to Rural Housings such as the relationship of characteristics of Rural Housings located in a Rural Village to the Village and a Unit Housing, to the External and Internal Spaces inside the Unit Housing and the Village, and to Living Characteristics of the Residents and Space from an integrated point of view. The results of this study are largely summarized as following four kinds. Rural Housing Survey System can be largely classified into three stages, and they are a Preliminary Survey, Basic Survey and In-depth Survey. Along with these, the scope of the survey contents can be divided into a survey result by a unit of village, of land, of housing, and of resident's opinion survey. Secondly, the surveys by village unit are on location properties, Village Identity, Street Network, Land Use, Landscape Features and Public Facilities, and consist of Literature, Discussion and Field Survey. Thirdly, the land Unit Surveys are on a Driveway, Gate Location, Housing Placement, Outer Space Design in a Yard and Outer Space Use Characteristics, and consist of Questionnaire and Field Surveys. For the fourth, the Housing Unit Surveys are on an Internal Space Design and Placement, and consist of Questionnaire and Field Surveys. Finally, the Resident Questionnaire Survey consisted of Entire Discussion Survey and a Household one, and then the Entire Survey was on the Village's History, Village's Characteristics, Cultivation Characteristics and Community Activities while an individual one was on Main Living Characteristics, Satisfaction and Utilization Characteristics.

Compared to the influences of Korean art journalism, the researches on them are rarely conducted. This study aims to examine the influence of art journalism in art magazines in Korea. Although it is essential to consider media, journalism, public opinion altogether, I focused only on the media due to the absence of previous studies I have analyzed the current conditions of korean art journalism, types of feature articles, sponsors, their relations with articles and the comparison with foreign art journalism in terms of production conditions. There have been about one hundred art magazines published in previous sixty years and currently there are twenty three. Monthly periodicals are the majority: the publishers are sorted out as publishing houses, galleries, newspaper company in order specialized art magazines developed from the eighties. Through an examination of feature articles in these art magazines, I found that they repeated similar art issues and covered the same artists sponsors and articles. Moreover, when the magazines went through the conflicts between managers and editors, the ascendency of managers obstructed the development of art journalism regarding journal quality. These days, art journalism have been comparatively regressed compared to other art systems such as art museums, curatorship, international aft festivals, distributions and art promotion policies. The main causes for failure were the lack of professional management, the limited effort to diversify sponsors, and the repetition of the same informants and events without making an effort to be specialized Magazines are published media which contribute to the creation of culture, distribution, and preservation. Therefore art magazines can be said the most influential media in forming art culture and distributing it. It is quite necessary to reform the problems of repeating of information and the lack of speciality in conjunction with the commitment of management and editorialship.

In this paper, we propose the data cache architecture with a write buffer for a 32bit asynchronous embedded processor. The data cache consists of CAM and data memory. It accelerates data up lood cycle between the processor and the main memory that improves processor performance. The proposed data cache has 8 KB cache memory. The cache uses the 4-way set associative mapping with line size of 4 words (16 bytes) and pseudo LRU replacement algorithm for data replacement in the memory. Dirty register and write buffer is used for write policy of the cache. The designed data cache is synthesized to a gate level design using $0.13-{\mu}m$ process. Its average hit rate is 94%. And the system performance has been improved by 46.53%. The proposed data cache with write buffer is very suitable for a 32-bit asynchronous processor.

Gwangju Metropolitan City has implemented a creative regeneration project of Gwangju Folly in the site of Gwangju-eup Fortress as part of the Gwangju Design Biennale by inviting well-known international architects. This study examined and analyzed the characteristics of location, place, and space through actual survey. The results were as follows. Gwangju Folly were mainly located at the four gates and corners of Gwangju-eup Fortress, main entrances of Asia Culture Complex, and historical places where the May 18 Democratization Movement occurred. The common place of Gwangju Folly was a footpath and common location types were the full location of footpath width and the partial location of footpath width. For the spatial types of Gwangju Folly, the practical type which people can stay was the most common(2/3). In the partial location of footpath width, the type which people take a rest and look out over the surroundings accounted for a half. In the full location of footpath width, the gate type which people pass accounted for 2/5. However, as footpath width was minimum for walking, both partial and full occupation types were narrow in place. It influenced the image of Gwangju Folly. Gwangju Folly did not play as a figure and show architects' intentions clearly because of their narrow locations. Therefore, it is very necessary to make a plan to maintain places so that Gwangju Folly do not have a cramped image and architects' intentions become clear with citizens' cultural competence. Also, urban property which creates the identity and attraction of Gwangju continuously should be settled down through helping citizens recognize the intention and value of artistic works.

SRAM-based FPGAs mainly used to develop and implement high-performance circuits have SRAM-type configuration memory. Soft errors in memory devices are the main threat from a reliability point of view. Soft errors occurring in the configuration memory of FPGAs cause FPGAs to malfunction. SEM(Soft Error Mitigation) Controllers offered by Xilinx can mitigate the influence of soft errors in configuration memory. SEM Controllers use ECC(Error Correction Code) and CRC(Cyclic Redundancy Code) which are placed around the configuration memory to detect and correct the errors. The correction is done through a partial reconfiguration process. This paper presents the availability analysis of SRAM-based FPGAs against soft errors under the protection of SEM Controllers. Availability functions were derived and compared according to the correction capability of SEM Controllers of several different families of FPGAs. The result may help select an SRAM-based FPGA part and estimate the availability of FPGAs running in an environment where soft errors occur.

Fast and accurate fault detection is the primary step and one of the most important tasks in fault tolerant converters. In this paper, a fast and simple method is proposed to detect and diagnosis the faulty cell in a cascaded H-bridge multilevel inverter under a short circuit fault. In this method, the reference voltage is calculated using switching control pulses and DC-Link voltages. The comparison result of the output voltage and the reference voltage is used in conjunction with active cell pulses to detect the faulty cell. To achieve this goal, the cell which is active when the Fault signal turns to "0" is detected as the faulty cell. Furthermore, consideration of generating the active cell pulses is completely described. Since the main advantage of this method is its simplicity, it can be easily implemented in a programmable digital device. Experimental results obtained with an 11-level inverter prototype confirm the effectiveness of the proposed fault detection technique. In addition, they show that the diagnosis method is unaffected by variations of the modulation index.

It was believed that Jeongnimsa temple was built after the capital was moved from Gongju to Buyeo. It was confirmed that it was built A.D. $625{\pm}20$ by conducting a paleomagnetic analysis on the fireplace, which was recently found at the bottom of Jungmunji(middle gate). Consequently, it is assumed that the temple was built in the early 7th century unlike the previous point of view. Therefore, this study evaluated if the fireplace at the bottom of Jungmunji was found at the geological stratum representing the Jeongnimsa temple. Moreover, the study examined when the fireplace at the bottom of Jungmunji was constructed on the soil stratum. It is possible that the fireplace was built in the early 7th century as shown in the paleomagnetic analysis. However, when we compared the soil strata of the Jungmunji and the existing five-story stone pagoda, it showed that the ground was prepared differently and they were built over a fairly long period of time. Furthermore, I discovered that there was a wooden pagoda under the five-story stone pagoda by examining the soil strata map. Therefore, previous studies evaluated the arrangement of auxiliary buildings of Jeongnimsa temple and concluded that it was built in the early 7th century. It is hard to determine when the temple was built based on the arrangement of auxiliary buildings, because it takes a long time to build a temple and auxiliary buildings can be relocated during this long construction period. Rather, we have to admit that there are various arrangement patterns through minor changes in buildings from the one pagoda and one main building(Geumdang) arrangement.

Recently, to achieve high performance of the processor, the cache is splits physically into two parts, one for instruction and one for data. This paper proposes an architecture of asynchronous instruction cache based on mixed-delay model that are DI(delay-insensitive) model for cache hit and Bundled delay model for cache miss. We synthesized the instruction cache at gate-level and constructed a test platform with 32-bit embedded processor EISC to evaluate performance. The cache communicates with the main memory and CPU using 4-phase hand-shake protocol. It has a 8-KB, 4-way set associative memory that employs Pseudo-LRU replacement algorithm. As the results, the designed cache shows 99% cache hit ratio and reduced latency to 68% tested on the platform with MI bench mark programs.

In this paper, we propose two main points. The first is the constraint for logic synthesis, and the second is an efficient logic synthesis method. Logic synthesis is a process to obtain the gate-level netlist from RTL (register transfer level) codes using logic mapping and optimization with the specified constraints. The result of logic synthesis is tightly dependent on constraint and logic synthesis method. Since the size and timing can be dramatically changed by these, we should precisely consider them. In this paper, we present the considering items in the process of logic synthesis by using our experience and experimental results. The proposed techniques was applied to a circuit with the hardware resource of about 650K gates. The synthesis time for the hybrid method was reduced by 47% comparing the bottom-up method and It has better timing property about slack than top-down method.
