Tetralogy of Fallot is a cyanotic congenital heart disease characterized by large ventricular septal defect[VSD] and stenosis of right ventricular outflow tract[RVOT] and the degree of RVOT stenosis and the state of pulmonary arteries are the major determinant of prognosis of this anomaly after operation. The sum of blood flow through RVOT and collateral flow from systemic arteries determine the total pulmonary blood flow and it is drained to left atrium and left ventricle. Therefore the degree of development of left ventricle not only reflects pulmonary blood flow and the status of peripheral pulmonary arteries but also affects postoperative prognosis as a systemic ventricle. In this article, left ventricular volume and its influence on postoperative cardiac function in tetralogy of Fallot were studied in 34 patients operated on at Department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital in 1985. Mean age of the patients was 5 1/12*3 9/12 years[range 9/12 - 14 8/12 years], mean body surface area[BSA] 0.65*0.20m2[range 0.38 - 1.22m2], mean body weight 15.6k6.48kg[range 7.0 - 36kg]and mean hematocrit 50.6*9.77%[range 32.0 - 73.5%]. Left ventricular end-diastolic volume[LVEDV] of them were from 11.2 to 113cc and there was a good linear correlation between BSA[m2, X]and LVEDV[cc, Y][Y= - 20.0+923x, r= 0.84, p < 0.005]. Mean LVEDV/m2 was [57.6 * 18.3 cc / m2[range 28.7 - 95.8 cc / m2] and there was a significant reduction of volume compared with normal value. As body surface increases, there was a increasing tendency in LVEDV/m2 but there was no statistical significance. Mean total amount of postoperatively infused dopamine in these 33 patients[except one who expired postoperatively] was 65.6*74.5mg / kg and it was 40.6*44.0mg / kg in routine RVOT widening group [Group I] and 205*49.3mg / kg in transannular RVOT widening group[Group II]. There was a statistically significant difference between two groups. In group I patients there was a good linear inverse correlation between dopamine total amount[mg / kg, Y] and LV volume[cc / m2, X] [Y = 150 - 1.89 X, r = - 0. 77, p < 0.005]. But there were no correlations between dopamine total amount and Hct, cardiopulmonary bypass time and aorta cross clamp time. In conclusion, the patient with small preoperative left ventricular volume required more amount of dopamine as an inotropic agent for the maintenance of a cardiac function in postoperative period. But this is a result of immediate postoperative period and does not reflect the long term effect of left ventricular volume in tetralogy of Fallot. There must be more study for the evaluation of its long term effect.
Between 1987 and 1995, eleven patients with severe chronic corrosive stenosis of the hypopharynx and esophagus underwent surgical restoration of digestive continuity at Inje University Seoul Palk Hospital. There were 7 male and 4 female patients aged from 21 to 47 years (mean, 34 years). The caustic material was acid in 6 patients and alkali in 5 patients. The esophagus was reconstructed using the right colon In 9 and left colon in 2. The cervical approach and the side of proximal anastomosis depended on the status of the pyriform slnus of the hypopharynx. In the neck, J-formed incision was made along the sternocleidomastoid muscle. The sternohyoid and thyrohyoid muscles were divided transversely to expose the thyroid cartilage. Hypopharyngeal opening for proximal anastomosis was made by reverse triangular formed resection of the thyroid cartilage after elevation of perichondrium. Immediately after operation, dysphagia and aspiration into trachea were common, so training of swallowing was required. Feeding gastrostomy was usually maintained for 3 months until restoration of swallowing function was confirmed . There was graft necrosis in 3 patients, who were treated with jejunal free graft. Revisional procedures for stenosis of cervical anastomosis in B patients consisted of widening of pharyngocecostomy site in 2 and resection of adhesive band in one. Return of normal swallowing assuring normal nutrition was obtained in 10 of 11 cases.
The purpose of this paper is to suggest the improving plans about the system as searching an effective managing devices for NEIS with analysis of managing condition. For the plans, questionnaire was performed in the five sections to primary and secondary school teachers. Those were recognition about C/S, Introduction and conductive processing of NEIS, Satisfaction of specific task on school affairs and educational matters, its function, efficiency and security as well as technical problem. Those were recognition about C/S, Introduction and conductive processing of NEIS, Satisfaction of specific task on school affairs and educational matters, its function, efficiency and security as well as technical problem. The results are following: First. in spite of satisfaction with function of C/S, it have been some problems such as frequent patch and down of server. Secondly, although the introduction of NEIS was done in hurry without gathering teachers' opinions and sufficient research of system, it has been expected to settle down normally with correction and security. Thirdly, positive reaction was generally showed in research on satisfaction of specific task for school affairs and educational matters. Fourthly, most of teachers have known the functions of NEIS and recognized its convenience. Although they has not thought it reduced their work, they have realized it's convenient for dealing with statistics. Lastly, they think of NEIS as the essential system for the age of information, in spite of problems such as reveal of personal data and security. Therefore, we should keep eyes to problem of an invasion of human right. In addition, study deep into NEIS should be conducted with consistent security for the system. In order to it. technical and legal system should be carried out side by side.

In u-GIS environment, GeoSensor environment requires that dynamic data captured from various sensors and static information in terms of features in 2D or 3D are fused together. GeoSensors, the core of this environment, are distributed over a wide area sporadically, and are collected in any size constantly. As a result, storage space could be exceeded because of restricted memory in DSMS. To solve this kind of problems, a lot of related studies are being researched actively. There are typically 3 different methods - Random Load Shedding, Semantic Load Shedding, and Sampling. Random Load Shedding chooses and deletes data in random. Semantic Load Shedding prioritizes data, then deletes it first which has lower priority. Sampling uses statistical operation, computes sampling rate, and sheds load. However, they are not high accuracy because traditional ones do not consider spatial characteristics. In this paper 'Pre-Filtering based Post Load Shedding' are suggested to improve the accuracy of spatial query and to restrict load shedding in DSMS. This method, at first, limits unnecessarily increased loads in stream queue with 'Pre-Filtering'. And then, it processes 'Post-Load Shedding', considering data and spatial status to guarantee the accuracy of result. The suggested method effectively reduces the number of the performance of load shedding, and improves the accuracy of spatial query.
In Korea, measures to maintain sustainable fire safety performance for apartment buildings are insufficient in terms of fire-fighting products, skilled personnel, and maintenance status. Also, because of the particular features of a fire compartment, it has structural problems that are very likely to cause damage to human life when a fire occurs. Currently, problems with the fire supervisory system installed in an apartment building cannot be checked in real time, so it is difficult to identify the location of a fire accurately. Protected areas are also not assigned to each household, and residents cannot be clearly informed of the occurrence of a fire. As a consequence, safety evacuation cannot be secured. In addition, it is impossible to test the operation performance for water detectors in sprinkler fire extinguishing systems outside of the household. Therefore, an experiment was conducted to evaluate the performance of a remote fire supervisory system. The results show that the system satisfies all performance requirements. Also, an household alarm system was installed in each household to alert of any occurrence of a fire accurately, and the performance of the alarm system was improved to ensure that residents were quickly evacuated.

This research investigates the historical changes of the educational system for the clothing departments at vocational high schools. According to the growth of the fashion industry, employment potential in the clothing departments of the vocational high schools, numerical changes in the educational statistics, and curriculums were investigated by papers, reports, and statistic data. The statistic data were derived from the 'Center Educational Statistics and Information', 'School Information' (Hak-gyo Alimi), 'Korean Statistical Information Services' and internet home pages of vocational high schools. Technical service workers that graduate from clothing departments and vocational high schools have limited competitiveness in a thriving fashion industry field. Highly developed fashion industries require more professional workers in fashion design, fashion marketing, and fashion materials. Compared to 1994, when 35 classes were conducted in 5 vocational high schools, 69 classes are now conducted at 15 schools. They have over 2,000 students and produce over 600 graduates. However, 222 credits of the $1^{st}$ curriculum in 1958 went down to 82 credits in the 2007 revised curriculum to complete the credits of clothing departments. The 15 courses of the 1st curriculum fell to 5 courses in the 2007 revised curriculum on the number of major subjects. It is a fundamental problem that major courses in clothing education have been excessively reduced despite the demand for of highly specialized workers in the fashion industry. In the view of operating conditions of those schools, there were several problems such as the wide gaps in the curriculum, limited equipment, the supply of teachers, and counseling on the choice of college or a career. In conclusion, the following measures are required: 1) the increase of complement credits in major subjects and renovation of curriculum, 2) national substantial support to change the social circumstance concerning vocational education and occupational consciousness, 3) operation of credit approving systems in universities and colleges for students that have completed the same courses at vocational high schools, 4) designing realistic programs for vocational education and cooperation systems with corporate enterprises.

In this study, we carried out a survey on the degree of recognition for the brand of the Korea Institute of Geoscience and Mineral Resources (KIGAM) to contribute to reestablishing the status and role of KIGAM as an institution that people proud of by effectively delivering KIGAM's various research activities and achievements to people. About 49.9% of external publics recognized that there was relevance between research achievements of geo-technology and national brand. On the contribution of research achievements of geo-technology to promoting Korea's power of science and technology, 42.3% gave positive answers. On research achievements of mineral resources technology, just 14.4% replied they saw such results. As alternatives to promote the degree of recognition for brand, we suggested development of beneficial message, operation of brand management committee, promotion of involvement of research achievements of mineral resources technology about people-friendly subjects, development and distribution of "board game for education on mineral resources technology" for youths, activation of location PR, activation of online Q&A bulletin board, finding out star researchers, and president's PI activities.

Recently, as new paradigm for government operation called government 3.0, government is actively operating policy opening and sharing public data. In addition, the Ministry of Land are operating an open platform integrated map service (the VWorld) which provides a variety of video contents such as the country's national spatial information, traffic information and three-dimensional building for the public. According to W3C Foundation's Open Data Status Report(2013), our country has the evaluated results that the part of the government's policy support and planning is good while the part of the data management is vulnerable. So our country needs the quality improvement for the data management. In addition, a digital aerial photograph image data is required to be up-to-date for the three-dimensional spatial object data. In this paper, we present the method for enhancement of the accuracy of vertical position and for maintainment of up-to-date vertical position. Our methods evaluate the data quality and analyze the cause of error of measurement utilizing the national standard quality assessment method. The result of research shows that the accuracy of vertical position is improved if the height of the building captain is adjusted by the quality assessment values and a three-dimensional model has up-to-date data if reconstruction and extension information of construction register is utilized.
This study closely analyzed the curriculum of the Christian Education Counseling Department and the general Education Counseling Department, and found the current status and problems of the curriculum of the Christian Education Counseling Department and the general Education Counsel Department. This study presented a balanced curriculum of the Christian Education Counseling Department with above analysis. For this purpose, the analysis focused on the educational operation process of Christian education counseling departments and general education counseling departments, such as educational goals, subjects, and counseling practical training. The Christian Education Counseling Department and the general Education Counseling Department are often combined with departments such as Christian Education, Youth, Children and Youth, and Lifelong Education, with the characteristics of convergence majors, so the basic subjects of the department were analyzed to have a higher percentage of subjects than counseling subjects. The results of the analysis showed that both departments lacked a considerable number of subjects related to counseling practical training. In the counseling course, the subjects of personal analysis, education analysis, counseling ethics, and counseling case super-vision for the professional development of counselors are still lacking, according to the analysis. In order to train counselors, it was analyzed that the system of systematic clinical practice system, various counseling analysis for counselor education, and the expansion of super vision subjects were urgently needed. In a modern society where the demand for counseling and the need for counseling experts are increasing as society becomes more complex, it is hoped that Korean universities will be able to actively contribute and cooperate in developing models of counseling education and training counseling experts through them, focusing on standardized indicators for fostering counselors.
In this study, the problems in the domestic disaster management system were identified through the examination of the system, relevant implications were drawn through the present status of domestic integrated disaster management system, and the consciousness survey for the integrated disaster management system targeting fire-fighting officers in the front line of the disaster was carried out to identify the measures to improve the system. Based on the findings, the measures to establish and revitalize the integrated disaster management system was presented, and the contents of the measures are as follows. In order to establish and revitalize the integrated disaster management system, the following measures should be prepared for each item. In the organizational aspect, the coordination system between government agencies should be established properly and the relevant information should he shared and delivered smoothly. In the legal and institutional aspect, the improvement is required to prevent any miscommunications in the coordination and joint operation plan through the collaboration between government agencies should be established in consideration of characteristics of each government agency. Also, in the aspect of system, the equipment should be maintained and updated continuously in order to respond to rapidly changing disasters and the organization, laws, institutions and system should be improved systematically and harmoniously. And, the detailed measures appropriate for the characteristics of domestic disasters should be prepared through the examination of advantages and disadvantages of integrated disaster management system in advanced countries in details and the detailed plans for the establishment of integrated situation management system in relevant organizations and the unification of situation room through the establishment of efficient integrated management system should be established.
