  • If we consider the origins of new architectural language in Russian, as opposed to its social dimensions, then we are looking at quite another area of pre-Revolutionary activity: art. It was Tatlin's early ‘counter-reliefs’ which first explored the way new materials might generate new artistic form. The Basis of his art is collage and the reality of materials. In 1915, he exhibited the first of his ‘counter-reliefs’, casual montages of pieces of metal that invade the space around them, making the decomposition of the forms three-dimensional. What is not in doubt is the primacy of materials in Tatlin's art. He was a key figure in the transition from art towards design and ‘construction’, the last was accomplished with ‘real materials in real space.’After the October Revolution, one of the central myths of avant-garde was the realization of a total work of art. The progress has developed in the directions to an unprecedented creative realm, situated somewhere between painting and architecture in the post-revolutionary period. Paramount among such pioneer works was Tatlin's design for a monument to the Third International in 1919. Here In an artistic form, his investigation of ‘material, volume and construction’ was clearly embodied. In the comtemporary architecture, Tatlin's concept has been a great influence on the various tendencies of spatial expressions. For example, the architecture with concept of ex-formality has many varied aspects of space composition - dynamic forms with plasticity of concrete, ex-cubic composition with free walls, disposal composition by geometric collision and superimposition, and etc.

  • We analyze the risk factors identified for ex-ante evaluation regarding government R&D programs. In particular, we empirically examined to what extent each risk factor is perceived to be important by the stage of R&D, technology field, researcher's career and experience. The empirical results show that technology risk is perceive to be less important for basic research, while market risk more perceived to be important in the IT field. Political risk is perceived to be less important for the university faculty, while researchers with government R&D project experience gave more value to legal risk factor.

  • The purpose of this research was to find out what is the dominant factor determining the $H_{ex}$ and the $H_C$ of Mn-Ir/Ni-Fe multilayers with different buffer layers. Regardless of (111) texture of Mn-Ir layer, all samples showed over the $H_{ex}$ of 155 Oe. We found out the $H_{ex}$ and the $H_C$ of Mn-Ir/Ni-Fe multilayers depend on interface morphology and grain size of Mn-Ir layer at the interface between Mn-Ir and Ni-Fe layers. The dependence of magnetroesistance ratio and coupling field on the thickness of ferromagnetic layer, thickness of Cu layer and different buffer layers have been studied. Maximum magnetoresistance ratio appeared for the sample Ta(5 nm)/Mn-Ir(10 nm)/Ni-Fe(7.5 nm)/Cu(2 nm)/Ni-Fe(6 nm)/Ta(5 nm)/Si. Magnetoresistance ratio may be related to grain of ferromagnetic layer. Coupling field may be related to the roughness and the grain size of ferromagnetic layer in the spin-valve multilayers.

  • This study conducted digital storytelling-based programing education targeting students at elementary school and analyzed educational significance as looking into perception on programing, making cognitive-affective assessments and having interviews. The results of the study are provided as follows. First, in terms of ex-post perception, from all the areas of fun, usefulness and ease of use, statistically significant differences were observed. It was also learned that female students have positive perception similar to male students. Second, the ex-ante and ex-post cognitive assessments came up with significant differences. Third, more affectively the class is developed, the number of students who would feel 'happiness' constantly increases. What the study has found there proves educational value of digital storytelling to programing education, and they will be used effectively as basic references for any relevant field to design measures for programing education of students at elementary school in the future.

  • According to Soil Taxonomy which has been developed over the past 20 years in the soil conservation service of the U. S. D. A, Soils in Korea are classified. This system is well suited for the classification of the most of soils. But paddy field soils have some difficulties in classification because Soil Taxonomy states no proposals have yet been developed for classifying artificially irrigated soils. This paper discusses some problems in the application of Taxonomy and suggestes the classification of paddy field soils in Korea. Following is the summary of the paper. 1. Anthro aquic, Aquic Udipsamments : The top soils of these soils are saturated with irrigated water at some time of year and have mottles of low chroma(2 or less) more than 50cm of the soil surface. (Ex. Sadu, Geumcheon series) 2. Anthroaquic Udipsamments : These sails are like Anthroaquic, Aquic Udipsamments except for the mottles of low chroma within 50cm of the soil surface. (Ex. Baegsu series) 3. Halic Psammaquents : These soils contain enough salts as distributed in the profile that they interfere with the growth of most crop plants and located on the coastal dunes. The water table fluctuates with the tides. (Ex. Nagcheon series) 4. Anthroaquic, Aquic Udifluvents : They have some mottles that have chroma of 2 or less in more than 50cm of the surface. The upper horizon is saturated with irrigated water at sometime. (Ex. Maryeong series) 5. Anthro aquic Udifluvents : These soils are saturated with irrigated water at some time of year and have mottles of low chroma(2 or less) within 50cm of the surface soils. (Ex. Haenggog series) 6. Fluventic Haplaquepts : These soils have a content of organic carbon that decreases irregularly with depth and do not have an argillic horizon in any part of the pedon. Since ground water occur on the surface or near the surface, they are dominantly gray soils in a thick mineral regolith. (Ex Baeggu, Hagseong series) 7. Fluventic Thapto-Histic Haplaquepts : These soils have a buried organic matter layer and the upper boundary is within 1m of the surface. Other properties are same as Fluventic Haplaquepts. (Ex. Gongdeog, Seotan series) 8. Fluventic Aeric Haplaquepts : These soils have a horizon that has chroma too high for Fluventic Haplaquepts. The higher chroma is thought to indicate either a shorter period of saturation of the whole soils with water or some what deeper ground water than in the Fluventic Haplaquepts. The correlation of color with soil drainage classes is imperfect. (Ex. Mangyeong, Jeonbug series) 9. Fluventic Thapto-Histic Aeric Haplaquepts : These soils are similar to Fluventic Thapto Histic Haplaquepts except for the deeper ground water. (Ex. Bongnam series) 10. Fluventic Aeric Sulfic Haplaquepts : These soils are similar to Fluventic Aeric Haplaquepts except for the yellow mottles and low pH (<4.0) in some part between 50 and 150cm of the surface. (Ex. Deunggu series) 11. Fluventic Sulfaquepts : These soils are extremely acid and toxic to most plant. Their horizons are mostly dark gray and have yellow mottles of iron sulfate with in 50cm of the soil surface. They occur mainly in coastal marshes near the mouth of rivers. (Ex. Bongrim, Haecheog series) 12. Fluventic Aeric Sulfaquepts : They have a horizon that has chroma too high for Fluventic Sulfaquepts. Other properties are same as Fluventic Sulfaquepts. (Ex. Gimhae series) 13. Anthroaquic Fluvaquentic Eutrochrepts : These soils have mottles of low chroma in more than 50cm of the surface due to irrigated water. The base saturation is 60 percent or more in some subhroizon that is between depth of 25 and 75cm below the surface. (Ex. Jangyu, Chilgog series) 14. Anthroaquic Dystric Fluventic Eutrochrepts : These soils are similar to Anthroaquic Fluvaquentic Eutrochrepts except for the low chroma within 50cm of the surface. (Ex. Weolgog, Gyeongsan series) 15. Anthroaquic Fluventic Dystrochrepts : These soils have mottles that have chroma of 2 or less within 50cm of the soil surface due to artificial irrigation. They have lower base saturation (<60 percert) in all subhorizons between depths of 25 and 75cm below the soil surface. (Ex. Gocheon, Bigog series) 16. Anthro aquic Eutrandepts : These soils are similar to Anthroaquic Dystric Fluventic Eutrochrepts except for lower bulk density in the horizon. (Ex. Daejeong series) 17. Anthroaquic Hapludalfs : These soils' have a surface that is saturated with irrigated water at some time and have chroma of 2 or less in the matrix and higher chroma of mottles within 50cm of the surface. (Ex. Hwadong, Yongsu series) 18. Anthro aquic, Aquic Hapludalfs : These soils are similar to Anthro aquic Hapludalfs except for the matrix that has chroma 2 or less and higher chroma of mottles in more than 50cm of the surface. (Ex. Geugrag, Deogpyeong se ries)

  • The purpose of this study was to examine the perception of cyber community participants on reconciliation of divorced couple and find reasons for pros and cons concerning reconciliation after divorce. The data were collected through searching for website or Internet cafe related to 'reconciliation after divorce' on Internet. The contents of 7 cases for asking for advice on reuniting and opinions of cyber community participants on them were analyzed. Cyber community participants expressed their approval of divorced couple's reuniting for following reasons: 'strong motive for reunion', 'sexual relation with ex-partner', 'parental responsibility', 'regarding reconciliation as a better choice than remarriage', 'regarding as a good choice for child' etc. But cyber community members were opposed to divorced couple's reuniting for following reasons: 'doubt about real intention to reuniting', 'no self-reflection on previous marriage and ex-spouse', 'concern for recurrence of former marital conflict', 'reuniting only for child not for couple', 'no prior settlement of former marital conflict', 'no forgiveness and tolerance for ex-spouse', 'no reflection and change', 'no effort on ex-spouse's side' etc. Though these results were restrictive, this study identified issues surrounding reconciliation after divorce through asking and giving advices by anonymous members on cyberspace. These findings implied that we should take more interest in reconciliation as an realistic alternative marriage pattern after divorce and consider what is important to successful reuniting after divorce.

  • To improve current transportation service, a new Seoul Metropolitan Transportation Administration (Seoul MTA), backed by Korean central government, is on the way of being established. This paper tries to answer questions such as 'What is the best type of organizational formation of the upcoming institute to deliver better, seamless transportation service?' and 'What is the most suitable scope of work of the upcoming institute to achieve the goal?' A group decision making process, a kind of AHP (Analytic Hierarchy Process) was adopted to measure the experts' preferences of alternatives in quantitative scale measurement. To evaluate the alternatives, five evaluation criteria were selected. Among them, it is revealed that 'Improvement of the transportation service' and 'Political & Administrative power to make it happen' are the two most important evaluation criteria over what types or operating costs of the administrations are. When the five evaluation criteria are applied onto the group of alternatives, it yields that a stand-alone organization, which should be independent from upper-level government body, should have an integrated and sole authority on the area-wide transportation system management.

  • In the simple application programs, when the Bluetooth system is used, main packet, which is transmitted or many overheads, which depend on processing between every level, lead to superfluous outlay of resource area. It is shown in this paper, that all layers of bluetooth system are not used. And, it uses up to HCI layer which it is supported to make a connection between bluetooth and host device(ex. PC, PDA, etc$\ldots$), should be used levels up to HCI layer. Therefore, it is able to transfer every part of data what should be transmitted.

  • This paper is the result of research what im-ply the shaman's costume in Korea "Kut" The implications can be summarized as follows: 1) Shaman's costumes in "Kut" are divided into two parts. Namely the one is the position as a priest and the other is the one as God it-self 2) Also shaman's costume were used to ex-press God's character in the ritual "Jae-Cha" These were based on the costume system by one's social position in the times of the Cho-Sun. 3) The reasons why shaman worn the tra-ditional costume are discussed variously. Among those reasons firstly shaman stands for the symbolic significance of each "Kut" as the agent of God. And secondly shaman wore to symbolize the miraculous virtue of God. symbolize the miraculous virtue of God.

  • An innovative Panel ExTension SATellite(PETSAT) and propulsion system for PETSAT, are presented in this paper. First, we outline what PETSAT is. Next, based on PETSAT ethos, design policy of the propulsion system is provided. According to the policy, we designed propulsion system and concretely estimated and assembled mono-propellant and bi-propellant systems, and it indicated that mono-propellant propulsion with 50-60 seconds of specific impulse and 1 N of thrust is probable. In the case of bi-propellant, 120-150 seconds of specific impulse is valid even based on the design policy. We conducted captive tests of mono-propellant and bi-propellant propulsions with a breadboard model of propulsion system for PETSAT, and obtained good operations and performances. Based on the test results, we designed and manufactured flight model propulsion system for PETSAT. We are planning to demonstrate it in SOHLA-2L project progressed by the Space Oriented Higashiosaka Leading Association(SOHLA). SOHLA-2L will be the first on-orbit demonstrator of PETSAT in 2008.
