The language of architecture is a kind of tool which helps people to experience the environment not as the thing itself but as a meaningful one. It, gathered by place, constitutes 'genius loci', as the existential structures. It, in other words, gives a thing 'cognitive quality', and serve people to 'dwell' because 'a place is a gathering thing with concrete presence.' Our environment, only when it possesses the language, presents itself as a namable thing or an understood world. Such a meaningful identification is dwelling. The modern world is a complex melting-pot. It is 'complexities' and 'contradiction'. The language of architecture is never created, rather it is selected by needs of the time and the place. In this sense, architectural design means discovery and interpretation of the poetic order of architypal form and style, and the poetic order is a way for people to dwell in the humanistic sense. These reminds me of Martin Heidegger's statement : "Architecture belongs to poetry, and its purpose is to help man to dwell."

The method to fabricate the cryostat of superconducting cable is extrusion type which is used Aluminum ingot under high temperature such as 45$0^{\circ}C$ and the cryostat is formed above cable core and MLI layer. In this case, it is expected to occur thermal injury in cable core and MLI layer, so it is necessary to study to prevent thermal injury. So in this paper, using simulation on radiation and convection which are accompany with fabricating cryostat, it is suggested to reduce the thermal injury. By measuring simulation temperature and real temperature, it is possible to check the temperature on cable core and MLI layer and using these temperature, it is possible to predict whether thermal injury is occurred or not on cable core and MLI layer.

The most fundamental topic of the Daesoonjinrihoe faith is how the human Kang Jeongsan can be supreme god(GucheonSangje). This statement is based on the Great Work of Sangje that is called Chunji-Gongsa. The documents on Chunji-Gongsa is founded in Jeongyung, the scripture of Daesoonjinrihoe. But it's not easy for us to understand it because of its holistic and symbolic expression. There are duplicate phrase of Chunji-Gonsa in one scripture or included it in another chapter that is not Chunji-Gongsa as well. So we need to analyze it more systematically and understand it reasonably. Especially in order to write this article I would like to use the view of Guchun-Sangje theory. This article is composed with three chapters except preface and conclusion. The first one is the relation between Chunji-Gongsa and Guchun-Sangje. The second one is to analyze Chunji-Gonsa. The third one is the doctrinal significances of Chunji-Gongsa.

A panic device is a type of door lock that opens when pressed or pushed by the body, so it is an emergency escape device designed to easily open the door and escape in an emergency situation such as fire or earthquake. It is an ideal door handle for an emergency exit. Because many people move quickly and it is easy to use, it is common in Europe and North America, but in Korea, the product is expensive, so it is used on a limited basis in luxury buildings such as hotels, but its use is gradually increasing. East Asian countries such as Korea, China, and Japan mainly prefer the North American type. The design of the penic device used in is a uniform and universal design, and research and development of a new design of the penic device was required to develop a new design type product considering the aesthetics of the building.

Today, it is not difficult to use information technology (IT), especially, Internet based ones. Many people can not only access IT without learning how to use it but also find and develop new techniques and usages which couldn't be expected by system engineers or designers. This is owing to social interactions among users as well as advancement of IT. Theoretically, such social interactions in using IT can be well explained by adaptive structuration theory (AST) which has been considered as one of trying to capture the change of using IT due to social interactions between users and system. This study is to analyze the relationship between social interactions and motivation in using IT which can determine attitude and intention of using IT. For this purpose we provide a research model, in which two AST related variables, faithfulness of appropriation and consensus on appropriation, are independent variables and three beliefs for using IT, usefulness, ease of use and playfulness, are dependent ones. Additionally, for reflection of changing uses, usefulness is formed as second order factor by two first order factors-usefulness of self-expression and communication. An empirical test of our model for blog users which is analyzed by Partial Least Square method shows supporting most of hypotheses except one, consensus-ease of use.

In the knowledge-based society, IT literacy and application of a person become a measure of personal competitiveness. As IT industry is of great important nationally, many countries are trying to make an effort to promote IT industry. In this sense, identification and fostering of the gifted children in IT become an important national task since, in IT industry, usually only a few prodigies have led whole IT industry. Currently gifted education aims for convergent gifted education according to government policy. The purpose of this paper is to investigate correlation of information subject and convergent subject for the gifted children in IT. For this purpose, the gifted children in IT who attended a gifted science education center attached to a university at Seoul Metropolitan Area are selected. Their grades during their the period of attendance are collected and analysed. The statistical results show that there is a meaningful correlation between information subject and convergent subject for the gifted children in IT. It means that the higher scores information subject is, the higher scores convergent subject is. The results can be used to make or change gifted curriculum and education contents for gifted IT education.

It is difficult to justify an IT investment unless the investment is expected to have a direct impact on a corporation's performance under rapidly changing business environment. It is important to demonstrate the benefit of the investment through a pre-investment assessment process to induce the executive's decision. This paper presents a methodology to assess the investment by analyzing cost and benefit of the investment. This methodology shows tangible cost as well as hidden cost by analyzing total cost of ownership. The methodology also produces ROI by performing cost benefit analysis including financial and non-financial factors. This paper suggests a systematic way to support If investment decision marking process by evaluating the investment objectively.

In this study, the initial number of bacteria before ozone sterilizing shows 290 per $1m{\ell}$ in RUN 1 and RUN 2 equally, but the removal rate shows more than 50% in RUN 1, and 100% in RUN 2 respectively when ozone injection amount is $0.28mg/{\ell}$. It is regarded as a satisfactory result that E-coli concentration without ozone contact is 890, rapid removal effect of E-coli is observed in $0.28mg/{\ell}$ of ozone, and E-coli is removed perfectly in $0.84mg/{\ell}$ of ozone. It is thought that an excellent efficiency is obtained for vibrio alginolyticus because the initial number of bacteria before ozone contact is positive, but it is altered to negative after ozone contact. CODcr shows the tendency which is somewhat reduced as the ozone injection is increased, but the general effect is appeared not so much, and it is thought that the tendency is caused by the reason that sea water contains much salt which is estimated as a component of CODcr, therefore it is regarded that ozone contact has not an important effect on salinity. It is thought that the frequency of changing salt water in the fish preserve of a sliced raw fish restaurant can be reduced to under the standard because NTU of 7 days after sea water injection is 0.70 in the experiment of turbidity, hut more than 50% of turbidity removal efficiency is appeared at $0.28mg/{\ell}$ of ozone injection, and it shows 70% at $0.84mg/{\ell}$ of ozone injection in RUN 1 and RUN 2 commonly.

The process of evaluating and selecting the best available techniques presents various characteristics for each country. In the case of EU, BAT is selected through TWG meeting after first screening, mass and energy balance, impact assessment and decision support process. Korea has proposed four principles to select BAT that can be carbon neutral for each environmental infrastructure in order to reduce greenhouse gas emissions. In order to evaluate and select the best available technique, it is necessary to differentiate the method according to whether it is a technique generally applied at the current workplace, whether it is a single technique or a combination technique, and whether it is a technology technique or management technique. In the case of a single technique, it should be evaluated whether it is a technique applied in the workplace, excessive cost, superior environmental technique over BAT, and secondary environmental pollution. In the case of multiple techniques, it is necessary to examine whether the emission standards are met and whether the pollutants can be treated at the same level as BAT. In the case of BAT candidates for management techniques, whether or not they contribute directly or indirectly to lowering the emission level of pollutants can be an important evaluation item. In the case of environmental techniques that are not generally applied in the workplace, it is recommended that the following 8 steps be carried out, including those prescribed by law. In the first stage, the list of performance evaluation factors is listed. In the second stage, the level of disposal of pollutants and the level of satisfaction with standards are listed. In the third stage, the environmental evaluation elements are listed. In the fourth stage, Is to list the economic evaluation elements, step 6 is to list the pollution and accident prevention evaluation factors, step 7 is the quantitative evaluation of the technical working group, and step 8 is BAT confirmation through deliberation of the central environmental policy committee.
