이 연구는 대안교육 특성화고등학교의 학교 밖 체육활동의 경험과 교육적 의미를 탐색하는 것을 목적으로 한다. 이를 위해 경기도 소재 대안교육 특성화고등학교인 D 고등학교의 교사, 재학생 및 졸업생을 연구 참여자로 선정하였다. 문서자료를 바탕으로 면담을 하였으며, 수집된 자료는 귀납적범주분석으로 분석, 해석하였다. 대안교육 특성화고등학교에서 학교 밖 체육활동 경험은 ‘학교 밖 체육활동의 의미 있는 교육적 변화’, ‘환경의 변화와 낯설음의 불편함을 통한 공동체에서 독립적 존재로의 경험 ’, ‘친구, 선생님, 자신과의 투닥거림’으로 분석되었다. 이러한 경험은 ‘학생, 교사와의 관계성 회복과 대인관계 기술 향상’, ‘아이들의 생활 전체를 조력하는 마음을 가진 교사’, ‘인성 체득의 가능성 탐색’이라는 교육적 의미를 시사하고 있다. 이를 토대로 학교 밖 체육활동이 대안교육의 본질적 가치를 실현하는데 교육적 역할과 사제(師弟)의 관계성 회복과 인성 체득 가능성을 통해 미래 체육교육에 대안을 제시할 수 있다는 의의를 제시하였다. 이 연구는 학교 밖 체육활동이 인성 함양, 사제 간 관계 회복을 통해 대안교육의 본질적 가치를 실현하는데 어떻게 기여 할 수 있는지를 보여주며, 학교 밖 체육활동을 체육수업으로 활용할 수 있는 방안을 제공한다. The purpose of this study is to explore alternative education characterization high schools’ outside-school physical activity experience and educational meaning. To address the goal, this author selected the teachers, students, and graduates of D High School, an alternative education characterization high school located in Gyeonggi, as participants. This researcher conducted interviews based on literature review, and the data collected went through inductive categorical analysis and interpretation. Outside-school physical activity experiences in alternative education characterization high schools are found to be ‘the meaningful educational change of outside-school physical activity’, ‘experience as an independent being in a community through environmental change and the inconvenience of unfamiliarity’, and ‘struggling with friends, teachers, and oneself’. This experience suggests such educational meanings as ‘the recovery of relationship with other students or teachers and improvement of interpersonal relationship skills’, ‘a teacher with a mind to assist the whole life of teenager’, and ‘exploring the possibility acquisition of character’. Based on that, this researcher suggests the implication about the realization of alternative education’s essential value that outside-school physical activity can provide alternatives to future physical education through educational roles, teachers and disciples’ relationship recovery, and the possibility acquisition of character. The study explains how the out of school physical activities can contribute to realizing the essential value of alternative education by fostering personality and restoring relations between teacher and student. and It provides the ways to utilize the out of school physical activities for physical education classes.

In zeolite separation membrane, there are defects which lower separation performance of the membrane. It should be noted that quantification of the defects is of great importance in order to compare performance of each membranes fabricated by lots of methods and structures. Here, we approached the quantification by first obtaining defects images from microscopy and second using those images to be image processed. In this paper, we introduce some efficient sequence of state-of-arts preprocessing methods for enhancing image segmentation result.

이 연구는 학습권보장제의 내용과 운영, 운동부와 학업활동에 미치는 영향에 대한 고등학교 탁구부 남자 학생선수의 인식을 심층적으로 탐색하는 데 목적이 있다. 이를 위해 경기도 소재 고등학교 남자 학생선수 4명을 연구 참여자로 선정하였으며, 2016년 12월부터 2017년 4월까지 참여 관찰과 심층 면담(8회) 자료를 수집하였고, 귀납적 범주분석을 활용하여 분석 및 해석하였다. 연구결과 첫째, 학생선수들은 학생선수 육성 제도 변화에 대해 원칙적으로 동조하고 있지만, 학업에 대한 양면적인 시각을 갖고 있다. 최저학력기준에 대해 관심이 적었고, 대회 출전 제한을 학습권 보장이 아닌 처벌로서 인식하고 있으며, 전반적인 학업 지원 시스템이 부실하다고 생각했다. 둘째, 학생선수들은 학업활동을 경기실적보다 중요하게 생각하지 않으며, 실효성 없는 최저학력기준은 학습동기를 저하시킨다고 생각했다. 지속적인 학습 결손으로 인한 학습무기력은 수업의 장애요인이며, 형식적인 e-school 지원은 무의미하다고 생각했다. 단. 수업 참여로 인해 일반학생과의 교우관계가 확대되는 것은 긍정적이라고 생각했다. 결론적으로 학생선수의 학업 참여와 지속성을 견인하는 실질적인 환경 조성, 학생선수의 학업 수준, 흥미 등을 고려한 맞춤형 프로그램의 개발, 학습권보장제에 관여된 다양한 이해 당사자의 의견 탐색과 정책 보완을 제안하였다. This study aims to conduct an in-depth exploration of the perceptions of high school ping pong club male student athletes regarding the effects of the contents and operation of the learning rights guarantee system on athletic clubs and academic activities. For this, 4 student athletes in high school located in Gyeonggido directly were selected as research participants and data was collected through 8th in-depth interviews and participative observations from December in 2016 to April in 2017 and analysis and interpretations were made using inductive categorical analysis. After the study, firstly, high school student athletes were agreeing with changes in the student athlete training system but had ambivalent perceptions regarding academic stress. They perceived thoughts of minimum education standards and restrictions on competition participation caused by these as punishment rather as learning rights guarantees and they considered the overall academic support system to be weak. Secondly, the student athletes considered that academic activities were still not as important as game performance and ineffective minimum education standards were seen to reduce learning motives. They thought that the ability to learn due to continuous learning deficits was a barrier to class, and that formal e-school support was meaningless. However, they considered the expansion of peer relationships with general students due to class participation to be positive. In conclusion, proposals were made for the development of customized programs that consider the academic participation of student athletes, the creation of actual environments that aid continuity, and the academic levels and interests of student athletes, and for the supplementation of policies through the exploration of opinions among interested parties regarding learning rights guarantees.

Algal dynamics is controlled by multiple environmental factors such as flow dynamics, water temperature, trophic level, and irradiance. Underwater irradiance penetrating from the atmosphere is exponentially decreased in water column due to absorption and scattering by water molecule and suspended particles including phytoplankton. As the exponential decrease in underwater irradiance affects algal photosynthesis, regulating their spatial distribution, it is critical to understand the light extinction characteristics to find out the mechanisms of algal dynamics more systematically. Despite the significance, the recent data have been rarely reported in the main stream areas of large rivers, Korea. In this study, the euphotic depths and light extinction coefficients were determined by monitoring the vertical variation of underwater irradiance and water quality in the main channel of Nakdong River near Dodong Seowon once a week during summer of 2016. The average values of euphotic depth and light extinction coefficient were 4.0 m and 1.3 m<sup>-1</sup>, respectively. The degree of light extinction increased in turbid water due to flooding, causing an approximate 50 % decrease in euphotic depth. Also, the impact was greater than the self-shading effect during the periods of cyanobacterial bloom. The individual light extinction coefficients for background, total suspended solid and algal levels, frequently used in surface water quality modeling, were determined as 0.305 m<sup>-1</sup>, 0.090 m<sup>-1</sup>/mg·L<sup>-1</sup>, 0.013 m<sup>-1</sup>/μg·L<sup>-1</sup>, respectively. The values estimated in this study were within or close to the ranges reported in literatures.

Dam reservoirs play a particularly crucial role in processing the allochthonous and the autochthonous dissolved (DOC) and the particulate (POC) organic carbon and in the budget of global carbon cycle. However, the complex physical and biogeochemical processes make it difficult to capture the temporal and spatial dynamics of the DOC and the POC in reservoirs. The purpose of this study was to simulate the dynamics of the DOC and the POC in Daecheong Reservoir using the 3-D hydrodynamics and water quality model (AEM3D), and to quantify the mass balance through the source and sink fluxes analysis. The AEM3D model was calibrated using field data collected in 2017 and showed reasonable performance in the water temperature and the water quality simulations. The results showed that the allochthonous and autochthonous proportions of the annual total organic carbon (TOC) loads in the reservoir were 55.5% and 44.5%, respectively. In season, the allochthonous loading was the highest (72.7%) in summer, while in autumn, the autochthonous loading was the majority (77.1%) because of the basal metabolism of the phytoplankton. The amount of the DOC discharged to downstream of the dam was similar to the allochthonous load into the reservoir. However, the POC was removed by approximately 96.6% in the reservoir mainly by the sedimentation. The POC sedimentation flux was 36.21 g-C/m<sup>2</sup>/yr. In terms of space, the contribution rate of the autochthonous organic carbon loading was high in order of the riverine zone, the transitional zone, and the lacustrine zone. The results of the study provide important information on the TOC management in the watersheds with extensive stagnant water, such as dam reservoirs and weir pools.
