  • In this paper, a client/server architecture and design concerns deduced from a real system design are described. The MIS system carried on IDIS is the one to be described. The experience from the system design is listed up and analized also. It is common to see that a distributed computing environment has much more complex structure than a conventional centralized one. As a consequence, a distributed system design is a complex task. It is worth to note that there should be sufficient considerations which had not been though ever for a centralized system. The objectives of this paper is to list up these problems and the solutions from experiences on a real system construction.

  • The purposes of this thesis lies in the study of marketable design through understanding of skiwear design and its market. This was done through the analysis of the present state of, and the growth of its market, modern fashion industry and the consumer, through skiwear related periodicals. I undertook the task of understanding current design trends through a study of catalogs by well-known ski wear brands, firsthand observation and photographing at ski resorts. The characteristics of present fashion industry lie in the realization of global merchandising, expansion of discount stores and tele-sales, demands for susceptible store interiors and change in consumer behavior. The market created outside of mainstream skiwear, focuses on the growth of the sportive mood over all areas of fashion, and among these developments. Skiwear trends begin to show tendencies to subdivide. Skiwear design can be divided into groups of functional sportswear for professionals, practical, snowboard-wear that combines as street-wear and finally elegant, feminine style.

  • This paper proposes the integration of photovoltaic (PV) and energy storage systems for sustained power generation. In this proposed system, whenever the PV system cannot completely meet load demands, the super capacitor provides power to meet the remaining load. A power management strategy is designed for the proposed system to manage power flows between PV array systems and supercapacitors (SC). The main task of this study was to design PV systems with storage strategies including MPPT with direct control and an advanced DC-link controller and to analyze dynamic model proposed for a PV-SC hybrid power generation system. In this paper, the simulation models for the hybrid energy system are developed using Matlab/Simulink, SimPowerSystems and Matlab/Stateflow tool. This is the key innovative contribution of the research paper. The system performances are verified by carrying out simulation studies using practical load demand profile and real weather data.

  • The paper is the principle of a curriculum, a recent method of teaching-learning in pedagogy, and intended for the exploration of the meaning of which reconstructs curriculum by narrative through practical exploration and narrative being discussed as the form of exploration. To date, Korean education showed an inclination of the traditional paradigm centered thinking and has emphasized the results by the method of scientific investigation. Even a curriculum reconstruction demonstrates documents that produce results without actually demonstrating the actual school setting. With communication one another is becoming increasingly important, we need the conversion of cognitive thinking that can express dilemma, contradictions, and complexities of the human world of which unexplainable by traditional paradigm mindset. Ultimately, the exploration of the direction that reflects a series of verbal, symbolic, and spiritual activities, which analyze lives of students, understanding and composing the meaning by using narrative, which talks about the experience of the human world in curriculums, is an important task for us.

  • In this paper, we introduce three monitoring filtering techniques which reduce the overheads of dynamic data race detection. It is well known that detecting data races dynamically in multi-threaded programs is quite hard and troublesome task, because the dynamic detection techniques need to monitor all execution of a multi-threaded program and to analyse every conflicting memory and thread operations in the program. Thus, the main drawback of the dynamic analysis for detecting data races is the heavy additional time and space overheads for running the program. For the practicality, we also empirically compare the efficiency of three monitoring filtering techniques. The results using OpenMP benchmarks show that the filtering techniques are practical for dynamic data race detection, since they reduce the average runtime overhead to under 10% of that of the pure detection.

  • Traditionally, the problems of manufacturing technology and manufacturing management have been treated independently. In this research, we endeavor to integrate the process planning and scheduling activities as an attempt to integrate the two realms. To draw up a plan of process planning and scheduling in real manufacturing environment is not an easy task because available time to plan could be limited and the shop status could change frequently. So we propose an architecture of integrated process planing and scheduling problem within the allowed time even if sheep situations change rather frequently. We argue that we can obtain a better and practical scheduling solution by dynamically changing the processing machines and operations as the shop condition changes. The proposed system takes the initial information for alternative machines and operations represented by an AND/OR graph as its input. Other informational inputs to the system are part order and shop statues. The system then generates new process plan and schedules during permitted time. Experimental results show that the proposed scheme provides a viable solution for real world scheduling problems.

  • Understanding of 'spatial' pressure distribution is required to determine design loads on local structures, such as plating and framing. However, obtaining a practical 'spatial' pressure distribution is a hard task due to the sensitivity of the data acquisition frequency and resolution. High-resolution Pessure-Idicating Flm (PIF) was applied to obtain pressure distribution and pressure magnitude using stepped crushing method. Different types of PIF were stacked at each test to creating a pressure distribution plot at specific time steps. Two different concepts of plotting 'spatial' pressure-area curve was introduced and evaluated. Diverse unit pixel size was chosen to investigate the effect of the resolution in data analysis. Activated area was not significantly affected by unit pixel size; however, total force was highly sensitive.

  • The purpose of this study is to provide a practical guide for selecting architectural artwork and analyze relationship between artwork and interior space & facade. The problems with many outdoor artwork did not make the characteristics of the specific environment and did not form a big flow in the urban contextualism. Choosing the artwork, architectural environment for artwork is very much part of the designers' task. When artwork is to be specifically acquired for a particular projects, designer and client must work together to make choices and plan placement. The data are collected through evaluation surveys of college students and graduate students majoring in interior architecture & design, and analyzed by using SPSS-WIN program to find the major characterized factors. It is concluded that architectural artwork should be constituted with nine major factors of interior space - theme/scale, situation/contemporay accord, finished materials harmony, line/two-three dimensional form, proportion/rhythm, sequence, natural/artificial form, abstract/reality expression, originality - and eight major factors of facade - situation, abstract/reality expression, finished materials harmony, theme/sequence, natural/artificial form, proportion/rhythm, static/dynamic expression, originality/. contemporay accord.
