The purpose of this paper is to analyse the industrial structure and competitiveness of five large cities in Korea. say Pusan, Taegu, Inchon, Kwangju, and Taejon. These cities are performing more important roles in this borderless society. Industrial competitiveness may not fully represent the competitiveness of a city, rather is one of the major constituents of urban competitiveness. The selected indices representing industrial competitiveness of a city include regional industrial share, location quotient, growth potential. productivity. profitability. The analyses reveal that all the five large cities are required the tasks for industrial restructuring in facing with the rapid deindustrialization trend. Inchon shows relatively competitive position in a number of industries, while the others are revealed weak in most categories of industries.

This paper examines the change of quality of life in the Integrated Yosu City and suggests the directions of urban development. Research into the quality of life in local and region scale is interesting both from the point of view of theory and practice, and has attracted much attention in the social sciences since the 1960s. This study is an attempt to examine the change of the quality of hie in the Integrated Yosu City. In the overall assessment of the level of satisfaction about the quality of life during the past five years, most of the respondents have positive evaluation of the changes of quality of urban life. In particular, the quality of living facilities, urban administration and convenience services has relatively improved during the past five years. On the other hand, the quality of physical environment. art and cultural opportunities, transportation options has been backward during the past five years. Therefore, the directions of urban development of the Integrated Yosu City may be summarized as follows: the establishment of a wide transportation network system, waterfront development, the activation of tourism industry and harbor works, the preparation of an urban landscape, the citizens'campaign for a community culture.

The aim of present study was to explore there were relationships among familism(collectivism vs. individualism), filial responsibility, and helping behavior of the middle-aged women towards parents. The respondents were 552 married women in their thirties, forties and fifties. OK Sun-hwa(1989)'s Seelbach (1978)'s, Cicirelli (1983)'s and Chang Sun-ju(1989)'s scale were utilized to tap the familism, filial responsibility, and helping behavior of the middle age daughter and daughter in low respectively. The major results of the study were summerized as follows; 1) Married women perceived relatively high levels of familism and filial responsibility and a moderate level of helping towards their parents and in-law parents as well. Among the demographic variables, education, income and age of the married daughters and daughters-in-law were found to be correlated to both familism and filial responsibility of support for their parents, Also, education and age were negatively related to helping behaviors. 2) Marred women reported similar levels of filial responsibility of support towards parents in law and their own parents, However significant difference were found between the amounts of helping behavior towards parents-in-law and their own parents. 3) Regression analysis revealed that living arrangement(living with parents or not ), the level of filial responsibility , and education level provided to be significant predictors on the helping behavior towards parent-in-law explaining 46% of the total variance. On the other hand, filial responsibility , living pattern, and income level for the parents were powerflu in predicting helping behavior towards their own parents accounting 24% of the total explained variance. 4) A path analysis model indicated that while educational level and living arrangement influenced directly to helping behavior toward parent-in-law, living arrangement, income level of parents and familism were directly associated with helping behavior for parents of their own. Therefor , helping behavior of the middles aged women was significantly mediated by familism and filial responsibility for support towards both parents-in-law and their own parents.

When an embankment is performed on the soft ground of the coastal with possibilities of lateral flow, lateral displacement occurs to the bottom of the surface of the ground. This lateral displacement can affect existing infra structures that are buried in the adjacent underground by causing a displacement in the nearby base foundation. Soft ground supporting piles and reinforced piles were applied as reinforcement remedies against the lateral displacement. And for the effect analysis, numerical analysis was performed under the classifications of non-reinforcement base and reinforced base. The result of the numerical analysis showed that the reinforced piles had more effects by 1.9 times than non-reinforced piles. Soft ground supporting piles showed better effects by 2.6 times than non-reinforced piles. Additionally, between the two reinforced remedies, soft ground supporting piles showed greater effects by 1.3-1.6 times than the reinforced piles.

Development of housing, industrial and public lands has been a cause to increase a temperature of a city higher than that of a rural area. Knowing that, the research analyzed temperature changes in a riverside district and a coastal area depending on the land usage and climate change in the areas. Add to this, the study examined a correlation between topographic characteristics and temperature changes. According to the results, the temperature was increased by $1.80^{\circ}C$ in 2007 comparing to 2003 while the wind velocity was reduced by 0.24m/s. In addition, a more number of areas were designated as build-up areas which, in return, decreased the forested land. The analysis on the correlation reported that the riverside district has more of grassland and bare land while the coastal area has more of wooded land and grassland. The study is expected to be used as fundamental data for research on heat island effect which would be different by each regional characteristic as it proposes measures to solve the heat island effect.

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.

To reduce the redundancy within samples that resulted from uniform sampling method, nonuniform sampling or nonredundant-sample coding methods can be considered. But it is well-known that when conventional nonuniform sampling methods are applied directly to speech signal, the amount of data required is comparable to or more than that required by uniform sampling method like PCM. To overcome this problem, we consider properties of speech signal in the sense of perception, and suggest a nonuniform sampling method at the maxima and minima of speech wave. To analyze the performance of the suggested method, compression ratio is considered. We show that compression ratio can be improved by silence detection, which can't be implemented by conventional methods based on uniform sampling. As experimental results, compression ratios of 1.54 without silence detection and 2.88 with silence detection for 8kHz 8-bit PCM signals are obtained.

The objective of this study is to analyze the propriety of the Biotope Area Factor's(BAF) application and propose an improvement plan. The BAP system, initially started by Seoul metropolitan city, is being settled in Korea. The BAF originated from the Biotop $Fl{\ddot{a}}chen$ Faktor(BFF) system of Berlin Germany. It was established as part of the Landscape Plan for the ecological function recovery in the high density built-up area with a sense of environmentally friendly urban management. The study compared the BAF's present condition of Ganddong-Gu, Seoul with Seoul's BAF system. Some problems appeared from the system application. Firstly, it may cause ecological damage if the site ranges are more than current BAF system limits. Secondly, the application of the current BAF system has the possibility of general redevelopment, but the partial improvement considering current standards of the high density built-up area's paving section is impossible. Lastly, division of the application object and application type are not divided well. In addition, the Seoul BAF which is currently applied across the board is based on the destruction of the natural area and low density built-up area. Accordingly, to improve these problems requires a complementary system protecting the ecological function prior to the application of the BAF and with restricted application to high density of BAF system built-up area.
