During the last two and a half decades, philosophical interest in the aesthetics of nature and environment has been gained momentum. One of the most coherent theories in this arena of debate has been developed over a series of articles by Allen Carlson. The purpose of this paper is to examine Carlson's theory critically and suggest an alternative aspect that remains untouched by his model. Briefly stated, Carlson's view of the appreciation of nature is that it is a matter of under standing nature under suitable scientific categories. His argument, based on the objectivist epistemology, is basically a disjunctive syllogism : a) The concept of appreciation, derived from traditional disinterestedness and Stolnitz's aesthetic attitude, provides an insight into the explanation of aesthetic appreciation of nature, and is objectivistic in the light of its object-oriented character. b) Nature must be appreciated as nature itself, and the natural environmental model is the appropriate loci of our nature appreciation. c) The paradigmatic form of our nature appreciation is order appreciation. d) There can be a correct and objective aesthetic judgment of nature, and the sources of guiding categories pertinent to it is natural science and natural history. In regarding nature as an environment and as natural, his natural environmental model is meaningful. Nevertheless, his stance results in some serious problems : a) The natural environmental model excludes certain very common appreciative responses to nature-responses of a less intellective, more visceral sort. Therefore, the arousal model with appropriate emotions might be one of our characteristic forms of nature appreciation. b) Even if we consider the scientific knowledge as an objective source of our nature appreciation, this gives rise to the question of whether the natural science can be objective or not. Is there an objectivist aesthetic appreciation of nature\ Does aesthetic appreciation of nature need to be science-based\

As most modern architectures had been constructed aiming at only both self-reliance and the purity without considering the place, the contemporary architectures have been also exposed to 'the loss of the place' similarly. From recognizing these problems, studying new spatial approach and various movements to create new modern place overcoming this have been progressed. It is meant that building shouldn't exist away from a land, without meanings. It is need to create new space aggressively against varying spaces. Thus, This thesis focus on architect Jean Nouvel among the architects having the insight of space and study his architectural design philosophy through his works creating new space. The aim of this study is to review how to define the 'placeness', and the light as a mediator of place. First of all, this thesis begins with a review what is the 'placeness' as spatial analysis and how to define 'light' as a mediator of place with his books, scholarly lectures, interviews, writing and papers and then analyse how light is represented through 'the place program of light' from his selected works. As a result of it, the thesis provides the possibilities of his constant challenges about 'existence-space-essence' by deriving the characteristics of 'the place program of light' focused on what his architectural approach constructs new space all the time through a regular program even if hard to define all his works as one model.

This paper proposes a new direction of technical highschool in Korea and presents a network model for technical highschool. As a distributed intelligent portal, the network model connects to anywhere and consists of simulated practical exercise in a school's self portal intranet. A title of the simulated practice contents developed in a school would be posted on any open site connected to the network model so that anyone who want to use it in his/her practice class could download to his/her intranet portal site. This mechanism works in two good ways. One is a wide area networkness and another is an easy utilization of broad band width since teacher could use the contents in his/her school's own intranet band width. The paper also emphasize that teachers and educators should make an effort to develop good quality meta-contents.

In these days, an individual is evaluated by his or her credit. So, it is very critical for an individual to know his or her credit rating and then to try to improve the credit rating. But, there are few services to analyze credit status for an individual and inform the person of the credit. In fact, it could be impossible to let a person know how to improve his or her credit rating. Against this backdrop, we research on a credit management model to analyze credit status of an individual rapidly and propose individual-customized method to improve the credit rating. We set up the model and design it in detail. This servie would certainly make it convenient for an individual to retrieve credit rating and improve it.

In this paper, vehicle tracking algorithm using hue transformation in HIS color model is proposed. the proposed algorithm is installed on the road of the two horizontal virtual data sampling lines. The difference images are detected between the frame and the frame, respectively and also detected in the vehicle by using the hue color distribution to determine identity and lane changes. To examine the effectiveness of proposed algorithm, identification and velocity measurement for driving vehicle are evaluated. this evaluated results is shown by hue data of vehicle passing of two virtual data sample lines, and the velocity measurement for driving vehicle is less than 0.4% comparing with existing vehicle speed meter system.

The performance of scientific researchers has been studied from a number of different aspects, mostly in developed countries. This paper attempted to identify salient factors influencing scientific performance at individual level in a developing country. A model describing the productivity and performance of scientific researchers was developed. Four hypotheses were derived from the model; i) the degree of diversity of a researcher will affect the degree of his scientific performance, ii) the degree of dedication will affect the degree of his performance, iii) the degree of research pressure will affect the degree of his performance, and iv) the degree of satisfaction will affect the degree of his performance. Data were collected through questionnaires responded by 48 researchers from two research organizations. The results of data analysis supported the hypotheses in part. Specifically, diversity measured by the number of research areas was related to the productivity of research reports (p<0.05); research pressure influenced the average number of research papers (p<0.05). The results of hypothesis testing of the satisfaction showed mixed directions according to the indicators. Even though the results of data analysis did not support the hypotheses unanimously, probably due to the limitation of sample size, most of the descriptive analysis indicated that the direction of hypotheses in developed countries seemed to be similar in developing country too. However, more research efforts are needed to verify the research findings of developed countries in developing countries.

- I aimed to isolate trans-acting factors involved in the basal expression level of eukaryotic genes. One of the yeast histidine biosynthetic gene, HIS5 was taken as a model for this study. HIS5 gene has a substantial basal level in amino acid rich medium and is derepressed if starved for any single amino acid. The derepression is mediated by cis-acting DNA sequences 5'-TGACTC-3' found in 5' non-transcribed region of the gene and trans-acting factors including GCN4 as positive factor and its negative factor GCDI 7, and GCNZ as a negative factor of GCD17. I first investigated the role of these trans-acting factors in HIS5 basal expression level by using HIS5-pH05 fusion in which expression of pH05 gene encoding inorganic phosphate-repressible acid phosphatase (APase) is regulated by HIS5 promoter. Strain with gcn2 or gcn4 mutation showed 3 to 4 fold lower APase activity than wild type. The level of APase activity was similar in gcn2 and gcn4 mutants. Trans-acting factors involved in basal level were identified by isolating 14 mutants showing increased expression of HISSPH05 fusion from gcn4 background. All the mutants carry a single nuclear recessive mutation and fall into four complementation groups, designated as bell (basal expression level), be12, be23 and be14.

Human gets almist all of his knoweledge from the recognition and the accumulation of input patterns,image or sound,the he gets theough his eyes and through his ears.Among these means,his chracter recognition,an ability that allows him to recognize characters and understand their meanings through visual information, is now applied to a pattern recognition system using neural network in computer. Recurrent neural network is one of those models that reuse the output value in neural network learning.Recently many studies try to apply this recurrent neural network to the classification of static patterns like off-line handwritten characters. But most of their efforts are not so drrdtive until now.This stusy suggests a new type of recurrent neural network for an deedctive classification of the static patterns such as off-line handwritten chracters.Using the new J-E(Jordan-Elman)neural network model that enlarges and combines Jordan Model and Elman Model,this new type is better than those of before in recobnizing the static patterms such as figures and handwritten-characters.

Harmony between men and their surroundings has been one of the most profound motives in space and object design for a long time. It is often expressed in design as the concept of 'organic'. Nowdays the term of organic is expanding its meaning in the contemporary sense of organicism. Nature, human 'beings, and digital technology are the key issues in future design paradigms. Karim Rashid is one of the most futuristic and vendible designer and his works show these issues. His designs flow organically and he uses materials that allow his forms to flow like the body, echoing life forms. it's very sensual, very tactile. In his work, a new concept of organic design is expressed in the organic unity of experience. He tries to contribute objects to our physical landscape that inspires, engages, and encourage positive experiences. Also, Technology is at constant play in his design process. With the latest three dimensional design software it is much easier to design and model sophisticated and complex shape and forms. Digital technology affects not only his design processes but also cultural views. New technologies and social shifts are changing our understanding of interior space.
