Objective : Subarachnoid hemorrhage(SAH) is still one of the most serious disease with high morbidity and mortality in the neurosurgical field. Clipping of the aneurysmal neck is the gold standard of the surgical treatment of aneurysmal SAH. The purpose of this study was to investigate the role of the postoperative angiography and to assess the risk factors related to the incomplete clipping. Materials and Methods : From July 1995 to June 1998, the pre- and postoperative angiography were performed in 50 patients among total 81 patients who have underwent the aneurysmal surgery. We reviewed the various contributing factors including age, sex, Hunt-Hess grade, Fisher grade and the premature rupture of aneurysm during operation retrospectively. Careful evaluation of pre- and postoperative angiography focusing on the size, shape, and remnant neck of the aneurysms and vasospasm was performed. According to the angiographic findings, the patients were divided into two groups ; a complete clipping group and an incomplete clipping group. The data were analyzed by using unpaired independent sample t test after F-test to compare the significance between two groups. Results : Incomplete clipping of aneurysms was found in 6(12%) patients through the evaluation of postoperative angiography. Among them, three cases were located on the middle cerebral artery territory. Whereas the patient age, sex, Hunt-Hess grade, and Fisher grade were not significant(p>0.05), an intraoperative premature rupture had a statistical significance(p<0.05). A severe vasospasm occurred in 24(48%) cases and one patient with anterior communicating aneurysm was reoperated due to residual sac. Conclusion : According to our experience, the surgeons' judgement is the most reliable factor in deciding the postoperative angiography. During the aneurysmal surgery, the premature rupture always disturbs a complete clipping of aneurysms. Therefore, the temporary clipping of parent arteries is considered essential for a successful clipping. We believe that the postoperative angiography has a role in decreasing the re-bleeding risk due to clip migration and an inaccurate clipping only in the selected cases.

When the crucial role of the agent in communicating with the customer is acknowledged well enough to relieve the agent's stress, it will lead to the decrease of the agent's emotional labor and the improvement of the business organization's performance simultaneously. However, the research on the relationship between information system and the emotional labor has been scarcely conducted even though the importance of the emotional labor is actively researched and discussed these days. Therefore, much effort has been put in this study to fine out how the quality of airline call center information system affects expectations-conformation and how expectations-conformation and self-efficacy affect performance of Emotional Labors. Analysis of the results to target a call center agent 436 people, When you provide them with quality information systems, it increased satisfaction and pride in their job. This mechanisms subsequently reduces the strength of the emotion labor, which ultimately improves the service performance. The implications of this study can be summarized as following: First, this research presented practical guidelines to the organization's decision-makers related to the airline call center operations in order to introduce and expand successful call center information system. Second, this research suggested the possible method to inspect and diagnose the system by way of applying the measurement model mentioned in this research into the airline information system and analyzing it. Third, the performance-measuring model developed in order to measure the performance of the airline call center information system can also be used when we carry out the performance-measuring task in the similar information system as the basis of diagnosing the situation and presenting the driving directions.

This study introduces the new role of science museums. The practitioners from seven domestic science museums and four overseas ones participated in this study and responded the questionnaires. I identified what kind of science culture programs there are, if those programs were successful or not, and if unsuccessful, what kind of improvements can be made to be successful. The participating practitioners in science museums also developed an ideal and realistic community cooperation-based science culture programs and I explored the role of a new science museum for this purpose. In the case of current science culture programs, the most successful or not was the participation of visitors according to public relations, and the importance of public relations were mentioned as improvements. For a successful community cooperation-based science and culture program, active promotion, pre-operation team, dedicated personnel, open mind, and same purpose of other institutions, the will of both institutions, and economic support sponsors are important variables. In the case of the domestic science museums, the actual development and operation of the program showed that a successful community based program must have cooperation with other institutions in the same region, win-win connections, the dedicated human resources, and that each science museum's strengths were maximized. The science culture programs in the 21st century will enhance the innovative role of science museums making the use of local human and physical infrastructure, reflecting the needs of citizens, taking the initiative in the community, fostering cooperation-based professional human resources, and communicating smoothly with the government or local governments.

In this study, we attempted to propose operational directions for each space in order to transform the newly built library in Yangpyeong-gun into a space for cultural enjoyment and creativity development for local residents. To this end, the purpose is to understand the space composition status of Yangpyeong-gun public libraries and establish an operation plan (draft) for the space to be constructed. To this end, we analyzed the names, operation status, and cases of similar spaces in other libraries, and analyzed the spatial characteristics of library cases to establish a space operation plan for the Yangpyeong-gun public library. As a result of the study, it is important to utilize spaces such as children's resource rooms to improve early reading habits for infants and children, contribute to development, and develop various senses, and small theaters should be planned with a focus on large-scale performances. Furniture and space for reading and relaxation should be provided next to Byeokmyeonga & Bookstair, and it should be operated as a communication space where small talk is possible within a certain limit. It is necessary to operate the multipurpose room by activating experiential creative activities and creative performances. It is necessary for the club room to establish an operation plan through regular communication and opinion sharing. The maker space space is a space that supports various creative activities, and the general data room is a place that provides materials on all topics and must be operated by regularly communicating with users and reflecting their opinions. Lastly, I would like to suggest that the family room should be used like a book cafe where children and parents can freely drink tea together in the same space.

This paper presents a PC cluster-based distributed video on demand (VOD) server that minimizes the load of the interconnection network by adopting channel bonding-based MVIA and the interval cache algorithm Video data is distributed to the disks of each server node of the distributed VOD server and each server node receives the data through the interconnection network and sends it to clients. The load of the interconnection network increases because of the large volume of video data transferred. We adopt two techniques to reduce the load of the interconnection network. First, an Msupporting channel bonding technique is adopted for the interconnection network. n which is a user-level communication protocol that reduces the overhead of the TCP/IP protocol in cluster systems, minimizes the time spent in communicating. We increase the bandwidth of the interconnection network using the channel bonding technique with MThe channel bonding technique expands the bandwidth by sending data concurrently through multiple network cards. Second, the interval cache reduces traffic on the interconnection network by caching the video data transferred from the remote disks in main memory Experiments using the distributed VOD server of this paper showed a maximum performance improvement of $30\%$ compared with a distributed VOD server without channel bonding-based MVIA and the interval cache, when used with a four-node PC cluster.

Mathematical knowledge is not exact definition but the supposition. Considering the nature of mathematics, realization of mathematics teaching which pursues critical thinking and rationality would be our problems. Accordingly, I set the subject of this study whether learning of constructivist discussion, which induces reflective thinking through communicating with others by expression with language of mathematical thinking in discussion, is effective against attitude on Mathematics and Mathematics achievement and study themes are as follows; A. Is learning of constructivist discussion effective against attitude on Mathematics? A-1. Is there any difference of self-conception on the subject between experimental group applied to learning of constructivist discussion and comparative group? A-2. Is there any difference of attitude on the subject between experimental group applied to learning of constructivist discussion and comparative group? A-3. Is there any difference of learning habits on the subject between experimental group applied to learning of constructivist discussion and comparative group? B. Is learning of constructivist discussion effective against mathematics achievement? The objects of study are 30 children of one class in the third grade of elementary school in Seoul for experimental group, and another one class with 30 children is comparative group. Study results and conclusion based on those results are as follows; First, students make reflective thinking through communication each other, therefore, instructor should create discussion environment for communication to express and form their mathematical thinking. Next, adaptability in student's mathematics activities and mathematical ideas should be permissible, and those should become divergent thinking. However, this study analyzed comparative results from only two each class having enrollment of thirty in the third grade. Accordingly, results from students in various grades and environment that are required to get more significant conclusion statistically.

A case of bladder prolapse through a patent urachus is reported in a female infant born with a large, red, tubular mass inferior to the umbilical cord. A cystic mass communicating with fetal bladder was detected by prenatal ultrasound performed at $20^{+2}$ weeks of gestation. A fetal MRI was also performed to confirm the diagnosis and to exclude associated fetal anomalies. At $40^{+4}$ weeks, the cystic mass was no longer present and a new small solid mass was noted at the fetal abdominal wall. After birth, a protruded mucosal mass inferior to the umbilical cord was noted, and catheterization confirmed communication between the protruded mass and the urinary bladder. On the second day of life, reduction of the bladder and partial resection of the urachus was performed. A voiding cystourethrogram showed good bladder capacity and no vesicoureteral reflux. The patient voided well and was discharged after 10 days. Here, we present a case of urinary bladder prolapse through a patent urachus, diagnosed by fetal sonography and this is the first case reported that was treated by simple excision without complication.

As the first class Teaching Artists system is about to be brought to effect, the ability required for Teaching Artists to design educational contents, develop and manage education programs is not much different from that of a museum Educator. This system is necessary for resolving problems in existing Arts and Culture Education, such as overlapping programs and adjusting difficulty levels by age to meet the demand of educatee. It also deals with drawbacks in production-oriented curriculum originating from the preference in some subject. In addition, as progress in science and technology makes rapid changes in digital media and its subculture, increasing need for novel and interdisciplinary curriculum in the field of Arts and Culture Education puts further emphasis on the importance of this system. In this study, we focus on clarifying the significance of Educator as a professional and proposing curriculum for the system, trying to avoid restricting our discussion to current Arts Instructor Supporting Project which are merely aimed at supporting children and adolescents to grow up to enjoy culture and arts. Capacity for designing curriculum for culture and arts, the kernel of qualification for the first class Teaching Artists, requires a variety of comprehensive expertise and qualification such as doing preliminary research on contents related to animation, curating, determining potential of educational contents, organizing educational contents for appropriate educatee, understanding esthetic property and its role in education, and appreciating and enjoying cultural contents. Therefore, Teaching Artists plays roles not only in developing and running educational programs but also in supporting and cooperating with culture and arts institutions, designing and managing creative programs, combining and communicating with different social groups, and emphasizing mutual interchange in culture.
