In this study, the porous polymeric membranes such as polycarbonate and polypropylene were casted by Robe method and prepared by a phase inversion process using supercritical CO₂as an anti-solvent. The porous polycarbonate and polypropylene membranes were prepared by polyethylene glycol and polyvinyl-alcohol, respectively. The obtained membranes have identical pore sizes of 2∼3㎛.

Objectives: The purpose of this study was to estimate the prevalence and correlated factors of high myopia in 19 year-old men in Southeast Korea. Methods: This retrospective study was based on the medical checkup data of conscription during 2005. The study subjects were 19 years old men in Busan, Ulsan and Gyeongsangnam-do. The health checkup data of the conscripts consisted of noncycloplegic autorefraction test, the biometric data and social factors. To analyze the social and biometric effects, we classified the biometric factors into 4 or 5 groups and the social factors into 3 groups. High myopia was defined as a spherical equivalent of under -6.0 diopter. Data analysis was performed using the chi square test for trends and multiple logistic regression analysis. The SAS(version 9.1) program was used for all the analyses. Results: The prevalence of high myopia was 12.39% (6256 / 50 508). The factors correlated with high myopia were the residence area (OR, 2.07; 95% CI, 1.77 to 2.4 for small city; OR, 2.01; 95% CI, 1.72 to 2.34 for metropolis; the reference group was rural area), academic achievement (OR, 1.43; 95% CI, 1.34 to 1.53 for students of 4-and 6-year-course university; the reference group was high school graduates & under) and blood pressure (OR, 1.54; 95% CI, 1.10 to 2.16 for hypertension; OR, 1.09; 95% CI, 1.02 to 1.17 for prehypertension; OR, 1.10; 95% CI, 1.01 to 1.20 for hypotension; the reference group was normal blood pressure). Conclusions: More than one tenth of the young men were high myopia as one of the risk factor for visual loss. Further studies on high myopia and its complications are needed to improve eye health in Southeast Korea.

Most people define education as schooling. But school is life space where exist many different kinds of phenomenon. Educational phenomenon is distinguished by structure of unique theory. If we don't distinguish educational phenomenon from the other phenomenons, term of “school education” would have ridiculous meaning as ‘school school’ or ‘education education’. Thus, research for solving educational problem in school should distinguish between educational phenomenon and schooling. I assumed that teachers organization had influence on many people's view of education. Furthermore, school was the center axis which was created or used terms of “education”. So in this paper, I made an attempt to deconstruct the concept of “education” included in “ChamGyoYuk” discussion of Korean Teachers and Education Workers Union. Firstly, I selected the typical examples using the term, and reviewed existence of the unique meaning. Secondly, I quoted the paragraph which had ambiguity, vagueness, contradictoriness, and redundancy of terms, and then I made critical analyses of those conceptions of “education”. Finally, I tried to replace those wrong concepts of “education” with appropriate terms restoring accurately with the context. 교육이라는 현상을 인식하는데 있어서, 그것을 고유한 이론체계로 포착되는 현상이 아닌 ‘학교라는 삶의 공간에서만 일어나는 일’ 또는 ‘학교라는 삶의 공간에서 일어나는 모든 일’로 인식하는 관례가 통용되어 왔다. 우리의 인식체계가 이러한 관례의 지배를 받을 경우 우리는 학교라는 삶의 공간과 교육이라는 삶의 양상을 구분할 수 없게 되며, “학교교육”이라는 용어는 ‘학교학교’라는 우스운 의미를 담아낼 수밖에 없다. 학교의 교육적 문제를 연구하기 위해서는 교육학의 고유한 이론체계를 통하여 학교 안의 교육현상을 포착하여야 한다. 이 연구에서는 “교육”이라는 용어가 생성되고 사용되는 중심부인 학교에서 다수에게 영향을 미치는 소수로 가정되는 집단을 교직단체로 보고, 그 중에 전국교직원노동조합의 “참교육”이라는 용어가 사용된 논의에 포함된 “교육”개념을 해체하였다. 이를 위하여 “참교육”이라는 용어가 사용된 기원으로 거슬러 올라가 현재까지 사용된 대표적인 용례들에 공통된 의미가 존재하는지를 검토하였으며, 용어의 중의성, 애매성, 모순성, 잉여성이 드러난 전형적인 사례를 인용하여 개념적 문제점을 분석하고 맥락에 적절한 의미를 찾기 위한 되돌리기를 실시하였다.
