From our analysis of pedestrian walking behavior at the Daegeon underground shopping center, we think that the following changes might be necessary to improve sign placement and use. First, the discrepancy between the location of information signs and their rate of use should be reduced. Second, differences in information given by the signs that arise from problems with sign height and placement should be reduced. Third, signs should be distributed in such a way that they provide co-ordinated information about points and places. Fourth, the arrangement and placement of the signs should be considered from the view point of pedestrian walking behavior. Because there is difference in the number of installed signs and the rate of use of these signs, to increase the rate of information use it may be necessary to adjust the content and placement of the signs. Furthermore, analysis of subject walking paths shows that it is necessary for information to be offered about connections between spaces.

This study analyzes the sign system, the types and distribution of sign boards, around Cheon-An railway station which is a representative public space, and it gives a classification of the system through investigating them by types and location. Some points are issued on the kind of the system established, the location of the information, and the clustered plantation of them. Thus, it is required to differentiate sign systems in each section, to distribute them uniformly rather than aggregated densely, and to place them at pertinent locations with the analysis of people’s behavior avoiding improvised decision.In conclusion, pedestrians’ needs on them should be analyzed first no matter where the sign is installed so that it is possible to develop tranquil atmosphere for people to use through providing proper information.

Recently, organic produts become popular. It is based on an elaborate marketing. An advertisement of Horizon Organic Milk shows a child has freckled face on a title ``You are what you drink.`` It`s an example of using a national emotion that wants to return to simler life getting out from fear like terrorism. A dictionary of organic produts is produced produts not using chemical pesticide, chemical fertilizer, radiation, genetic technology, hormone, antibiotic, and so on. In the past, organic food was thought `the thing sold for specific consumers at specific market`, but it becomes more common. Thus, I could know package design is changed to design that makes charge and sympathy from consumers by expressing natural images getting out from the standard images.

멀티미디어를 주요 처리 대상으로 하는 포터블 임베디드 시스템은 데이터에 대한 빈번한 메모리 접근으로 인하여 처리 속도가 저하되는 문제점에 직면하고 있으며, 이를 해결하기 위하여 임베디드 프로세서 설계 과정에서 데이터 선인출 기법을 채택하고 있다. 이 논문에서는 임베디드 시스템의 주요 성능 척도인 전력 소모 측면에서 데이터선인출이 시스템의 성능에 미치는 영향을 분석하였다. 이를 위하여 데이터 선인출 기법이 추가된 메모리 시스템의 전력 분석 모델을 제안하고, 응용 프로그램 수행에 소모되는 전력을 모의 측정하였다. 실험 결과, 데이터 선인출은 응용 프로그램의 처리 시간을 단축하는 반면 전력 소모를 크게 증가시키는 것을 확인하였다. 더불어 데이터 선인출을 채용한 임베디드 시스템에 대하여 처리 속도와 전력 소모를 함께 고려하는 성능 분석 모델을 제안하였다. Portable embedded systems which mainly handle multimedia applications involve the problem that frequent accesses to fetch data from memory make running time increased. To cope with the problem, embedded processors have adopted data prefetching schemes. From a power point of view, which is a main performance indicator of embedded systems, this paper analyzed to investigate how data prefetching schemes influence on system's performance. To solve the problem, we proposed a power-consumption analysis model of a memory system with data prefetching scheme and measured the power dissipated during running application programs. As a result data prefetching schemes have application program's running time reduced but have system's power increased. Also we proposed a performance analysis model considering execution time and power consumption for embedded system with data prefetching schemes.

We Studied the method of structuring the sign system for pedestrians in the underground space by investigating and analyzing the sign system at Tae-jon Underground Commercial Area in Korea by 1) classifying the signs by types and comparing their numder for each type in sections, 2) classiflying the signs by the points of installation, types, functions and contents of information and comparing their numbers, 3) classifying the signs by their height and comparing by the points of installation, and 4) classifying the signs by their points of installation finding patterns. As a result, we found out that the current pedestrian signs in Tae-jon Underground Commercial Area could by classified into those installted with a certain regularity and those concentrated in at certain points. We also found out that there were many problems with the current signs system. The big gap of the type and numble of the signs, concentration of the signs at the gate (entrance), and the big gap of the function of the signs by their points of installation. And the gap of the signs by the number of installation is big between the North side and the South side. Most of signs concentrated in the South side show the problems of installation attached by the types and quantity of information. We suggest that type of information has consistency by posting of signs, at the same time, the necessary information should be offered in order for the pedestrians to easily recognize as they more in the Underground space. 본 연구는 지하공간에서의 보행자를 위한 사인 시스템의 구축 방법에 관한 연구로, 대전시 지하상가의 사인을 사례로 이하의 조사를 실시하였다. 1)지하상가에서의 사인의 종류를 구분(區分)하고, 구간별(區間)종류의 기수(基數)비교.2)사언을 설치장소별(別),종류별,기능별,정보내용별로 구분하고, 그 기수의 비교.3)높이에 의한 사인의 종류를 구분하고,설치장소별에의 비교.4) 설치장소별 사인의 패턴(pattern)화. 그 결과, 현재 대전시 지하상가에서의 보행자사인은, 규칙적으로 일정하게 설치되어 있는 일정형(一定型)과,설치 장소에 따라 밀도 (密度)의 차(差)가 큰 밀집형(密集型)의 분포특성으로 나눌 수 있었다. 또한,사인의 종류와 기수의 차가 크고 사인이 출입구에 집중되어 있는 것, 사인에 있어서 설치장소에 따라 기능의 차가 큰 것에서, 설치장소에 따른 정보의 불규칙한 집중과 개성의 유무(有無)둥의 문제점이 나타났다 .그리고 북측( 北測)과 남측(南測)에서의 사인의 설치 수(數)에 차가 크고, 대부분의 사인이 남측에 집중되어 있는 것에서 정보의 종류와 양(量)에 있어서 편중(偏重)된 설치 상의 문제점이 나타났다 . 이에 해결책으로 사인을 설치함에 있어서 정보의 종류에 일관성을 가짐과 동시에 장소에서의 인식이 쉽도록 적절한 정보제공의 필요성을제시하였다

Today, the main work that occupies the majority of the car industry is Model-change. Frequently, compared with Europe, Model-change is short cycled and it has been done in Japan`s market which is a small-scale. The method and the form of Model-change functioned as a chance to the product improvement including quality of each design. Therefore, in every case, clearly reflecting sense of values and the culture in the age, they contain a lot of varieties, and it has contributed to the creation of new sense of values. In this article, the evaluation and consideration of those typical Model-changes were tried from the aspect of product design. As a result, various forms and concepts in the background of age and corporate strategy were confirmed. Those are the enhancement of lineup by addition or independence according to Model-change, or, inner evolution by consolidation of some car types. It was recognized again as the factor common to them that the distinctiveness of the vehicle design was in Stuck to shape which was actually the origin of product design.

This study discusses the flow of information regarding buildings connected via an underground space. Common information is installed although there are a small number of signs in the Tenjin underground center that provide directions to the buildings that are connected to the Tenjin underground shopping center. The data show that the sign format in private sector sites (private spaces) connected to the underground shopping center (public space) is different from the standard sign format and content used in the underground shopping center. Thus it is apparent that there is a need to integrate the format of the information signs in the two spaces (public and private).
