Objective: The lumbar spinal canal can be devided into the central zone and the lateral zone. The divisions of the lateral zone are the subarticular, the foraminal, and the extraforaminal zone. A common causes of the operation for the spinal stenosis are related to the association with the spondylolisthesis and the central stenosis. There is a paucity of data, however, regarding the operative intervention in the lateral zone stenosis(LZS). Our aim was to analyze the surgical result by the anatomical type and the operative method. Methods: 72 patients of LZS excepting the association with the spondyolisthesis have been operated by six neurosurgeons of our hospital from 30th April, 1994 through 30th September, 2002. The patients had been interviewed about surgical result through telephone by third party persons. The surgical results were analyzed by the four score rating system: ① medication, ② ADL(Ability of daily living), ③ the degree of improvement, ④ the degree of satisfaction. Results: Among 72 patients, there were 25 males and 47 females. The age group of the patients were in their thirties(1), forties(9), fifties(21), sixties(36) and seventies(5). Surgical methods were used on decompression(22), posterior lumbar interbody fusion(PLIF) with cage(1) and PLIF with transpedicular screw fixation system(49). The types of stenosis were subarticular(24), foraminal(16) and extraforaminal(30) and double crush(2). The overall surgical results were Excellent(18), Good(34), Fair(19), and Poor(1). The Non-success rate according to the methods of surgery were decompression(34.8%), PLIF with transpedicular fixation system(24.4%). The overall success rate was(53/72: 73.6%). The success rate according to the types were subarticular(17/24: 70.8%), extraforaminal(21/30: 70%), and foraminal(12/16: 75%). Conclusion: It is suggested that the result was more favorable on the cases of lateral zone stenosis operated with PLIF and transpedicular fixation system. According to the method used, the success rate of decompression was worse than PLIF with transpedicular fixation system.

본 연구에서는 세종시 개발지역 학교의 학교입지․통학환경․교육여건․적정규모에 대한 실태를 탐색하고, 교육공동체의 요구 분석자료를 바탕으로 향후 효과적인 학교 설립방안을 모색하든데 목적이 있다. 이를 위한 연구문제로 첫째, 세종시 개발지역 학교의 개교부터 현재까지 학생수 변화 추이 및 다른 신도시의 차이점은 무엇인가? 둘째, 과대․과소학교 발생으로 인한 학교입지의 문제점은 무엇인가? 셋째, 안전한 통학환경 조성을 위한 학교입지 상 문제점은 무엇인가? 넷째, 적정 배치를 위해 개선해야 할 점은 무엇인가?로 설정하였다. 연구방법으로 학부모와 교직원을 대상으로 설문조사를 실시하였다. 그 결과, 첫째, 학교설립 시 적정한 학교입지를 최우선으로 하고, 둘째, 학교를 공동주택 중심에 위치하고 학교용지 옆에 회차로, 학부모드랍존 설치, 셋째, 운동장 및 특별교실․돌봄교실 부족 문제를 해결하기 위해 학교용지를 일정 면적 이상 확보, 넷째, 저출산에 따른 학령인구 감소에 대비하여 통합운영학교나 학교시설복합화 등 다양한 방안으로 모색할 필요가 있다. This study explores school location, school environment, educational conditions, and appropriate scale of schools in the context of Sejong City’s development area and identifies effective school establishment plans based on the analysis of the needs of the educational community. The research questions for this study include, first, what is the change trend in the number of students as a result of the opening of schools in the development area of Sejong City to the present, and what differences are there between Sejong and other new cities? Second, what challenges arise in school location due to the occurrence of oversized schools and undergraduate institutions? Third, what challenges arise in school location that would limit the ability to create a safe school environment? Fourth, what aspects need to be improved in school location decisions to promote proper placement? A survey was conducted among parents and faculty members to collect data. The findings revealed that first, when establishing a school, identifying an appropriate location for the school was the top priority of the respondents. The second was the proximity of the school to dense housing, with a parent drop zone next to the school site. Third, to address the issue of lack of playgrounds and special class and care classes, respondents called for various measures such as securing school sites within a certain area. Finally, integrated operation schools and school facilities are required in preparation for decreasing school-age populations due to low birth rates.
