Given the our life environment being the original space which surrounding human today's our environment turned in the artificial and dried space because it's focus on planned and made by city's function and efficiency. So Isamu Noguchi is try to express the formative space which can live nature and human, and human and space together just for a bit. And he succeeded to create the new molding formation named the environment and sculpture to deeply get the problem on nature of place and understanding of place for aesthetic satisfaction. So he makes great contribution towards the monument and field of environmental sculpture. So this thesis is for making clear the importance of space for the sculpture and effect on Isamu Noguchi's environmental sculpture by analyzing the various artworks by Isamu Noguchi and studying his space concept and space sensation of his through generating the experiment of space and eclecticism. Noguchi pursed the harmony with the artwork by expending the architectural space to the full, and he focus his energies to left the artwork which with the public in their lives.

Comparing with Seoul city's other administrative works, the work to arrange and collect monthly water rates with 470,000 faucets is tremendous in volume and simple repetition in quality. In order to cover the shortage of handling, it is urgent for us to replace the present manual system with EDP(Electronic Data Processing) system to mechanize a series of handling works of simple repeated calculation such as water consumption, rate calculation, statistics arrangement, bills and specification of water rate by computer. When this work is completely mechanized, inspectors of water meter just turn over their checking results to the Data Center and all data are processed through Input Media(OMR Card, Punched Card) and computer for programming final bills. Then, the delivery of the bills to citizens will be the only work to be carried out. such mechanization will bring about the following benefits: 1. Improvement of administrative work by efficiency and rationalization. 2. Improvement of administrative service with people. 3. Possibility of scientific with trustworthy multi-purpose policy-making data. 4. An effect to cover the personnel shortage of 252 persons (at all the water works offices) and save manpower of 166 persons (47,619 man-days). The application of the above mentioned mechanization will be started to only Chongro and Chung-ku water works offices as model cases out of all water works offices in Seoul. As the electronic calculating machines are inducted, this system will be gradually applied to other water works offices. The billing and collection works of water rates which are connected directly to the daily life of the citizenes, should be handled by the scientific EDP system as soon as possible in order to promote the convenience of consumers and effective operation. This study is to promote the sound and rational operation of this work.

The purpose of this paper is to investigate if any effects of GI cooperative learning method, which is compared to the effects of traditional competitive teaching-learning method on the students' academic attitude in middle school social studies classes. Conclusively, it is asserted to be a much more effective teaching-learning method. Some statistical evidences were gathered by questionnaire method just after the experimental classes being applied for a semester to the 241 first year middle school students in a small city. Using the t-test procedure, it is conformed that GI cooperative learning method can draw much more positive changes in the academic attitude of the students. In short, such positive changes in student's academic learning attitude can be related with the increase of self-trust in learning processes, the change in the conception of the subject, and the spontaneous interaction and verbal communication among the group members.

This paper has attempted to improve the quality of urban environment in terms of the management of urban green tract and suggest a way of coexistence between human and nature by proposing a plan to establish green network using an urban green zone based on 'linear concept' instead of point and plane concepts. The results have turned out as follows: 1. According to current status of forest functions, forest recreation area has reached 39.6%, satisfying citizens' needs. However, the space for living environment is just about 20% with a lack of a green zone. Therefore, it's been necessary to establish green network using roadside trees and take advantage of them as sustainable living space along with existing green tract. 2. With forest in the suburbs and Geumhogang which is the tributary to the Nakdonggang, Sincheon (stream) flows through the downtown. It connects mountains including Waryongsan from the south to the north around Duryu Park and Dalseong Park. Therefore, the water system that passes through Palgongsan (Mt.) and Biseulsan (Mt.) would make it possible to connect with the parks in the downtown. 3. According to this paper, it appears that it's necessary to establish green network through roof or wall greening by focusing on the existing green tract in the urban parks and suburbs and taking advantage of roadside trees and water system.

Many idealizations and ideal conditions in physics have been an important role in understanding of the basic physics concepts and in solving physics problems. The purpose of this study was to explore the relationships of pre-service teachers' misconception of heat with their understanding of the ideal conditions involved in solving problems of heat and temperature. Test instruments were composed of two parts. One part was asked to answer the heat conceptions, the other to write statements in relations to ideal condition hidden in the process of heat problems solving. For this study, pre-service teachers who are in four major courses in the University of Education in a local city were selected and total numbers of pre-service teachers were 108 students. The framework was developed for classifying pre-service teachers response of open items of ideal conditions of heat domains. According to the framework, each types of response were coded, analyzed and processed with a SPSS/PC program. The results are as the followings. In the heat conceptions, most of students showed correct response, and there was no significant differences between major courses. In understanding of ideal conditions, students' responses of "idealized condition relevant to problem" showed 65.2％ of them, and "not relevant idealized conditions" 15.5％, and no response 12.2%. In the 15.5% of students "not relevant idealized conditions", 10.5％ of them did not explained correctly conditions, just simply 2.7％ stated the laws in physics or formula, 1.6% generally, but irrelevantly described the idealized conditions. More importantly pre-service teachers showed very weak correlation between heat conception and understanding of ideal condition. Although we concluded there were no significant relationships of heat conception in understanding of ideal conditions in thermodynamics domain, these suggest that many other factors may influence understanding of ideal conditions in physics.

In the late 16th century, the Theatrum Anatomicum or anatomical theatre opened in Leiden in the Netherlands. The theatre was open to a fee-paying audience of students, surgeons, and the public and soon settled down as one of the highbrow cultural activities in the city. This trend soon spread into Amsterdam, and Nicholaes Tulp appearing in Rembrandt van Rijn's was at the center of it. Human anatomy was not just an eyesore but started to get accepted as a cultural event for the civilized citizens of the time. It was with this backdrop that Rembrandt got inspired by this interesting scene of Tulp dissecting human body. Rembrandt well understood the changes of the time and captured them on canvas to attempt convergence between science and art.

With a rapid growth of domestic industry in korea, now about 25,000 kinds of chemicals are being distributed, and it has been known that just about 15% of them has toxic substances. Recently, South Koreans have an anxiety about the stability and accidents of chemicals because chemical accidents like Gumi hydrofluoric acid accident have occurred. The U.S. has adopted the systems like EPCRA (Emergency Planning and Community Right-to-Know Act), TRI (Toxic Release Inventory) and TSCA (Toxic Substances Control Act), and is also managing the hazardous chemicals by providing the information about them to its people and site workers. Japan's Ministry of Health, Labor and Welfare also has adopted J-CHECK system and is implementing it to let Japanese people know the information of safety of chemicals about REACH. However, the Korean government has a difficult situation to mediate the different idea with the Korean industry to make lower statute of Pre-legislation registration & evaluation of chemicals that will be implemented and Chemical Material Control Association that is being implemented. Especially city and country areas located in the industrial areas need political improvement focusing on vulnerable area through the check about current situation of hazardous chemicals of jurisdiction and management method, but the information about the management situation of small scale work places is insufficient. Therefore this study set up the urgent management area in Ansan Smart Hub through NFPA code according to the types of accident and dander characteristics of each chemical being used in the companies that have less than 50 workers and deal with chemicals located in Ansan Smart Hub in Gyeonggi-do.

Singapore government is strongly promoting the development and utilization of underground space in national level due to the nature of the city state which lacks the land. As well as conventional underground utilization in shallow depth such as metro and underground roads, large rock cavern utilization has been started after the successful completion of the underground ammunition depot in the rock, and Jurong Rock Cavern, the second large underground cavern project has just been completed. In this paper, after evaluating the conditions of the underground development in rock mass through the analysis of the geology of Singapore, the history and current status of underground development are examined. Several creative development plans from Singapore government such as underground reservoirs, underground automation logistics systems and underground warehouses storage etc. are introduced with technical issues. This paper also discusses the problems and issues related to the development of large underground space in rock mass in Singapore. It is expected that such active development of underground space in Singapore can give many opportunities and also challenges for rock engineering and industry in the future.

This is a follow-up study on Han and Kang (2013) which argued that the Euclidean distances between /o/ and /u/ in Seoul Korean decreased in the first syllable position as speakers were among younger female speakers but not for male speakers, whereas in the second syllable position both gender groups showed a cross-generational decreasing effect of the Euclidean distance between /o/ and /u/. This study normalized the same data in Han and Kang (2013) which measured 12 speakers (six males and six females) for each Age group and investigated the spectral changes vowels /o/ and /u/ between age and gender, using the log-mean normalized statistical results. This study also examined overlap fraction values generated in SOAM 2D ($F1{\times}F2$) (cf. Wassink, 2006), which may also indicate the proximity of two vowels in question. The results showed that /o/ and /u/ vowels were making closer with /o/ raising for female speakers in $V_1$ and $V_2$ positions but only in the $V_2$ position for male speakers. That is, females led the upward movement of peripheral /o/ vowel, just like the raising of 'e' and 'o' in New York City (Labov, 1991). The results also showed that younger speakers used a rather narrow vowel space for the vowels. This also contributed to the proximity of the vowels /o/ and /u/, resulting in rather large overlap fraction values for younger speakers between these two vowels.

The nonlinear effects on the statistical properties of wave groups in terms of the average nomber of waves in a group and the mean number of waves in a high run is studied in this paper utilizing the complex envelope and total phase function, random variable transformation technique and perturbation method. It tures out that the phase distribution is modified significantly by nonlinearities and it show systematic excess of values near the mean phase and the corresponding symmetrical deficiency on both sides away from the mean. for the case of threshold crossing rate, it turns out that threshold crossing rate reaches its maxima just below the mean water level rather than zero and considerable amount of probability mass is shifted toward the larger values of water surface elevation as nonlinearity is getting profound. Furthermore, the mean waves in a high run associated with nonlinear wave are shown to have larger values than the linear counterpart. Similar trend can also be found in the average number of waves in a group.
