  • Kinematic characteristics of a heavy rainfall event occurred in Changma front are analyzed using synoptic weather charts, satellite imagery and NCEP(National Centers for Environmental Prediction) / NCAR(National Centers for Atmospheric Research) reanalysis data. The heavy rainfall is accompanied with mesoscale rain clouds developing over the Southwest region of Korea during the period from 0300 LST to 2100 LST 25 June 2006. The surface cyclone in the Changma front is generated and developed rapidly when it meets following vertical conditions: The maximum value of relative vorticity is appeared at 700 hPa and is extended gradually near the surface. It is thought that the vertical structure of relative vorticity is closely related with the descent of strong wind zone exceeding $10ms^{-1}$. The jet core at 200 hPa is shifted southward and extended downward and the low-level jet stream associated with upper-level jet stream appeared at 850 hPa. Kinematic features of heavy rainfall system at cyclone-generating point are as follows: In the generating stage of cyclone, the relative vorticity below 850 hPa increased and the convergence below 850 hPa and the divergence at 400 hPa are intensified by southward movement of jet core at 200 hPa. The heavy rainfall system seems to locate to the south of the exit region of upper-level jet streak; In the developing stage of cyclone, the relative vorticity below 850 hPa and the convergence near surface are further strengthened and upward vertical velocity between 850 hPa and 200 hPa is increased.

  • The purpose of this study was to find out the residents' consciousness of the unit plan on condominium apartment and to contribute to develop a condominium apartment unit plan in Daejeon City. This research was performed by a questionnaire survey method, 464 data was collected from apartment residents lived in about $85\;m^2$ unit with 3 rooms and the apartments was limited to the complexes within 1-4 years of the length of building at Yuseong-gu and Seo-gu. By analyzing those data, findings are as follows: 1) Residents thought living room, kitchen and bathroom were importment space in a unit plan. They needed a storage function in an entrance and a intermediate room, and Anbang(mater bedroom) so did. 2) L-DK plan type was very popular and the type of front DK with L on the floor plan was preferred. This was unique results. 3) Sub-kitchen was needed for a refrigerator of Kimchi, the location of it was related to a main kitchen and a utility. the third room was needed for library, home office and storage space. 3) Bath-tub in An-bang and showe-booth in public bathroom was preferred. This was same to the popular trend of Korean condominium apartment. 4) The enlargment remodeling of balcony was showed livingroom balcony or personal bedrooms at the time of occupancy. They needed the balcony near a kitchen or an utility to equip a storage facility. Additionally, residents were preferred to their taste rather than a choice of interior concept package services.

  • Although over - 600 students in Incheon has been participated in the gifted education programs under the colleges and Office of Education Department every year, it is reported that the number of teachers have insufficient teaching abilities in primary, advanced, and after-advanced gifted classes. The Gifted Education Research Institute in Incheon University introduced R&E activities for the improvement of teachers' abilities in science research and student guiding. Professors in science department conducted the R & E activities to select the research thesis. The professors and the guidance teachers decided the directions of the research, and the guidance teachers who learned from the professors taught 3-5 students to practice the research. Five professor-teacher-student research teams in math, physics, chemistry and biology conducted the research after school and during the vacation for 7 months. The results of the research were submitted to the journals of research activities and the result papers were presented to the seminar. On this research, the possibilities and the difficulties of the R&E activities based of the journals of research activities, oral presentation and the research results reports were analyzed with a purpose of improving the professionalism of the science gifted teachers. Although the professors proposed many difficulties or problems about the R&E activities, the teachers reported that the R & E activities he1ped them to improve their research activities and student guiding techniques. The teachers acquired more knowledge on the principles of the science related areas than before. Moreover, they thought it was very meaningful experience in using the science related instruments, guiding the students' research and writing the research reports. The students also gave the positive responses with the increased interests in new science studies and with the experience of learning the way of research.

  • 지식정보사회에서 컴퓨터교육의 필요성 및 중요성은 계속 강조되고 있다. 그러나 현재의 초등학교 컴퓨터 교육은 컴퓨터활용만을 위주로 전개되고 있는 형편이다. 그러나 응용 SW의 기능 습득을 통한 기계적 사무 처리 능력 향상이나 교육용 SW의 단순한 활용 측면의 접근용 지식정보사회의 요구에 부응하기 어렵다. 그러므로 이제는 창의적이고 논리적인 사고를 바탕으로 계속적으로 변화, 발전하는 지식정보사회의 사회적, 문화적인 환경을 이해하여 새로운 가치를 창조하고 지식을 형성하기 위한 본질적인 과학으로서의 컴퓨터교육이 필요한 시기라 여겨진다. 따라서 본 논문에서는 현 컴퓨터 교육의 문제점을 토대로 초등컴퓨터교육과정 변화의 필요성을 제시하고, 지식정보사회에서의 초등학교 컴퓨터 교육과정의 변화 방향에 대한 현장 교사들의 의견을 조사하였다. 또한 현재 초등학교 컴퓨터교육과정을 ACM과 미국 노스캐롤라나주, 캘리포니아주의 초등학교 컴퓨터교육과정을 중심으로 비교 분석 하여 초등학생을 위한 컴퓨터교육과정을 제시하였다.

  • This paper aimed to compare the daily water quality as well as the hydrological data gathered for the past two years (2000 to 2001) between the two influent rivers of Paldang reservoir. The analysis also has been carried out to draw out the factors that affect the water quality at the dam site, where the main drinking water drawing point is located. The relationship between total amount of monthly rainfall and monthly inflow showed $r^2=0.74$ (p<0.05). The highest peak of inflow of influent rivers recorded in August and September (in the year of 2000) and July and August (2001). Average inflows of influent rivers in 2000 and 2001 are calculated at 209.0, 161.5 CMS (Bughangang), 268.6, 148.2 CMS(Namhangang), and 7.8, 5.0 CMS (Gyeongancheon). The formula which was driven from the relationship between inflow and COD load of influent rivers, explained that COD concentration in general increased with the inflow. But during the rainy seasons (July, August, and September), COD concentration decreased according to the increase of inflow. The daily rainfall and COD concentration(or load) during the rainy season (August and September in the year of 2000, July and August in 2001) indicated that the peak of COD load correspond with the rainfall, which decreased sharply after 3 or 4 days. The reason was thought that the high COD load was diluted rapidly by the rain flow. Water temperature, pH and conductivity measured at dam site decreased obviously when the inflow sharply increased. Peak period of total phosphorus concentration coincided with that of inflow. In rainy season, chlorophyll-a concentration decreased obviously as the inflow increased. The reason can be ascribed to the flushing effect caused by the operation of floodgate.

  • The purpose of this study is to analyze the actual status of costume exhibitions displayed in architectural structures heritage today to examine if they play proper roles as visual materials and suggest the necessity of post-management for comfortable viewing. This is significant in that it makes costume exhibitions function as educational culture contents to let Korean and also foreign viewers know of our costume culture properly. As a research method, the database of the Office of Cultural Properties homepage was used to extract anything related to the lives of figures during the Chosun Dynasty among the architectural structures heritages in Seoul, Incheon, and Gyeonggido. By doing so, the costume exhibitions were able to be examined among them. With field investigation and interviews of related institutions, this study examined the current status of costume exhibitions, planning of exhibitions, and post-management. Also, they found costume exhibitions that were not right for the era, and suggested ways that were more appropriate for them. The results of this study were as follows : First, according to the third selection results, there were only six among 71 places where three districts of the architectural structures heritage were present. This is a very small quantity of places when compared with the total number of architectural structures heritage. Second, as a result of the current condition investigation, the costume exhibition in the Architectural Structures Heritage is not nearly enough for a historical investigation, and almost all polluted costumes were not displayed in suitable environments for an exhibition. Therefore, qualified managers who have expertise in exhibition planning were needed to be trained to do a post-management follow up. Furthermore, it is important to systematically reorganize post-management methods. Third, the two selected places(Haepung-buwongun-yuntaegyeong-jaesi and Sunaedong-gaok) were thought not to be right for the era among the six places with costume exhibitions, and suggestions such as flat-drawing and illustration were made.

  • Purpose - The development of technologies lead the volume of sale on online market increase but an off-line shopping center is still a core component in the omni-channel strategy. It is generally thought that high-level retailtainment on brick and mortar store affects purchase intentions positively, but some previous studies dispute that and have reported that retailtainment does not affect purchase intentions. So we have studied the additional factors' effect - the nature of purchase and utility - with retailtainment. Research design, data, and methodology - There are 8 treatment groups which were assigned by the method of retailtainment (high vs. low), nature of purchase (essential vs. non-essential), and utility (acquisition vs. transaction). A total of 240 subjects (office workers = 163, 68%; undergraduates = 77, 32%; average age = 30s; female = 39%) were divided into groups and exposed to one of the eight scenarios. Participant's purchase intention was the dependent, and ANOVA and L-matrix were used to analyze for main and interactive effects between factors. Results - First, the main effect and interactive effect between retailtainment and the nature of purchase are significant. We also found that the contrast between essential and non-essential at low-level retailtainment is higher than that of high-level retailtainment. Second, in the case of retailtainment and utility, transaction utility under high-level retailtainment affects purchase intentions positively. Third, between the nature of the purchase and utility, the main effect of the nature of purchase and the interactive effect is significant, but the main effect of utility is not significant. In the case of non-essential goods, the purchase intention was high when transaction utility was provided but in the case of essential goods, acquisition utility increased purchase intentions. Finally, when transaction utility is given, purchase intentions of essential goods increase under low retailtainment, and the purchase intentions of non-essential goods increase under high retailtainment. Conclusions - When customers buy essential goods, discounts decrease purchase intentions. During the season for bargain sales, purchase intentions increase when retailtainment of essential goods is low, and retailtainment of non-essential goods is high.
