최성우 동아대학교 1997 국내석사

現在 飮食物 찌꺼기의 일일 發生量이 일만오천톤을 넘어섰고 조리되는 總 飮食物의 15%가 再活用되지 못하고 쓰레기로 損失되는 금액이 거의 일년 에 10조원에 육박하고 있다. 또한 1995년부터 쓰레기 從量制가 실시됨에 따라 飮食物 찌꺼기의 處理에 대한 間題가 크게 대두되고 있다. 우리나라의 경우 飮食物 찌꺼기의 대부분을 埋立과 燒却에 의존하고 있는 실정이지만 埋立 後 發生되는 惡臭, 浸出水 發生 및 埋立空間 不足 등의 問 題가 있으며 燒却할 경우 發熱量 減少 및 燒却의 非效率性 등의 問題點이 대두되고 있으므로 再活用을 위한 새로운 補完對策이 필요하다고 볼 수 있 다. 따라서 本 硏努에서는 飮食物 찌꺼기에 韓國 고유의 술인 濁酒 製造에 利明되어 온 누룩을 種菌劑로 添加하여 嫌氣性 醱酵에 미치는 影響과 嫌氣性 醱酵時의 生成 가스種과 發生量 및 嫌氣性 醱酵 後의 乾燥特性 등을 檢討하여 飮食物 찌꺼기의 再活用에 대한 可能性을 提示하고자 한다. 嫌氣性 醱酵 實驗을 행하여 水分含量, TS, VS, Cl^(-), pH, 부피 減少率, IR, 惡臭, 가스 發生量, 가스 性狀, 乾燥率 등을 分析하여 본 結果 飮食物 찌 꺼기에 누룩을 添加하여 이틀간 嫌氣性 醱酵시키면 初期 含水率이 80~85%이던 것이 脫水되어 약 60% 以下로 減少되었고 전체 飮食物 찌꺼기 부피 도 약 30% 정도 減少되었다. 또한 初期 鹽分 濃度가 2.3%에서 누룩 醱酵 後 약 1.7%로 減少되었고 누룩을 添加하여 飮食物 찌꺼기를 嫌氣性 醱酵시 키면 嗜好性이 向上되고 惡臭가 減少하였으며 알코올과 有機酸 生成에 의해 長期間 保管이 可能하였고 누룩을 添加하지 않고 嫌氣性 醱酵 시킨 飮 食物 찌꺼기 보다 乾燥가 빨리 進行되므로 以上의 結果를 檢討해 보면 飮食物 찌꺼기를 飼料化 등으로 再活用時 누룩 添加가 肯定的인 效果가 있음 을 알 수 있다. This study has been carried out in order to reduce the moisture content of waste food and improve the drying effect of waste food. After adding Nuruk, the results from anaerobic fermentation experimentation, kind of producing biogas, biogas production and drying experimentation was summarized as follows ; 1.

Water management is one of the powerful strategies to mitigate greenhouse gas emissions in particular methane (CH₄) in flooded rice paddy soils. The drainages greatly reduce methane emissions but may significantly increase nitrous oxide (N₂O) emission during rice cultivation, requiring optimum level of soil moisture to trade off these two opposite greenhouse gas emissions. The objective of this study was to evaluate the feasibility of precise water control on effectively mitigating greenhouse gas emissions and water usage as well as improving rice productivity in flooded paddy ecosystems. In this study, a pot experiment (1 2000 a-¹) was conducted to maintain six different moisture contents (two flooded conditions, four drained conditions) during whole rice cultivation season : (i) 100%-high (maintaining water level, 7.5 cm from the soil), (ii) 100%-low (2.5cm), (iii) 90%, (iv) 80%, (v) 70%, and (vi) 60% of total soil porosity (soil volume 9322㎤, BD 1.07 g cm^(-3), PD 2.6 g cm^(-3)) based on volume water content by using a moisture sensor and supplying water by hands. During the cultivation, CH₄ and N₂O emissions were monitored by using static chamber methods twice in a week, and soil moisture content was monitored by using a soil moisture sensor. Soil physical and chemical properties, rice productivity, and the amount of total water input were analyzed after the rice harvesting. In this study, CH₄ emissions significantly decreased with decreasing soil moisture contents, showing lowest value at 90% which was no significant difference among the drained conditions. However, N₂O emission significantly increased with increasing soil moisture contents, showing highest value at 80%, and then sharply decreased. Global warming potential (GWP) was lowest at 100%-low which effectively mitigated N₂O emission during rice cultivation although the CH₄ emission was recorded as second highest level among all the treatments. Rice productivity was highest at 100%-low due to increased panicle number and number of grains per panicle, showing lowest GWP per yield index as a promising and sustainable way. The amount of total water input during whole cultivation period was highest at the 100%-high treatment and then gradually decreased with decreasing soil water moisture contents, showing lowest total water input per rice yield. Our study suggests that maintaining low level of the flooded water could be a promising way to maintain rice yield and to mitigate greenhouse gases emissions, in particular N₂O in paddy ecosystems.

최성우 한국체육대학교 사회체육대학원 2011 국내석사

이 연구는 12주간의 규칙적인 운동이 치매노인의 인지기능, 혈당 및 혈중 지질 성분에 미치는 영향을 규명하는데 목적이 있다. 경증치매환자 14명을 대상으로 12주 동안 주3회, 1회 60분 복합운동을 실시하였으며, 운동 전ㆍ후 2회에 걸쳐 한국판 MMSE(Mini mental state examination)와 혈압, 혈당 및 혈중지질(TC, TG, HDL-C)을 측정, 분석하여 다음과 같은 결과를 얻었다. MMSE-K는 운동군에서 운동 후 향상하였으나 통계적으로 유의한 차이가 없었고, 혈압은 운동군에서 수축기 혈압의 유의한 감소가 나타났다. 혈당은 운동군과 대조군 모두 유의한 차이가 나타나지 않았다. TC는 운동군의 경우 운동 후 감소하였으나 유의한 차이가 나타나지 않았고, 대조군의 경우 증가하였으나 유의한 차이가 나타나지 않았다. TG는 운동군의 경우 운동 후 유의하게 감소하였고, 대조군의 경우 증가하였으나 유의한 차이가 나타나지 않았다. HDL-C는 운동군의 경우 유의하게 증가하였으나 대조군의 경우 유의한 차이가 나타나지 않았다. 이상의 결론을 종합해 보면, 운동군의 경우 수축기 혈압이 감소되었고, TG, HDL-C 수준이 유의하게 개선되었다. 하지만 비교군의 경우 TC, TG 수준이 증가되었다. 이는 12주간의 복합운동이 피험자들의 지질대사를 개선시켜 심장과 뇌혈관 질환의 위험인자를 감소시키고 치매 진행 지연 및 인지기능이 감소되는 것을 예방하는데 긍정적인 효과가 있다고 생각된다.

본 연구의 목적은 인권의 관점에서 한국 장애인운동의 전개과정을 고찰하고, 이를 통해 장애인들의 인권확보를 위해 장애인운동이 나아가야 할 방향성과 향후과제를 모색하는 데에 있다. 역사적인 전개과정은 생존권운동, 노동권운동, 교육권운동, 이동권운동으로 나누어 각 운동의 역사적인 전개과정을 살펴보았다. 장애인운동은 다음과 같은 역사적인 특징을 갖는다. 첫째, 장애인운동에 있어서 장애인당사자의 참여와 요구로 제안이 시작되고 실현되었다는 긍정적인 측면을 지녔다. 둘째, 경증장애인 중시에서 중증장애인의 권리와 삶의 문제로 무게중심이 점차적으로 전환되었다. 셋째, 장애문제의 접근이 복지의 관점에서 인권의 관점으로 서서히 가치관이 전환되었다는 긍정적인 시각이 등장한 것을 알 수 있다. 이렇듯 본 연구를 통해 장애인운동의 역사적인 특징을 발견하기는 하였지만 정책결정과정에서 장애인운동이 보다 많은 영향력을 행사하고 대중적 지지를 얻는데는 조직 내ㆍ외적인 한계점을 발견할 수 있었다. 이러한 한계점을 극복하고 장애인운동의 계속적인 발전(진보적 장애인운동)을 위한 과제는 다음과 같다. 첫째, 장애인운동의 대중적인 기반을 확보하고 강화해 나가야 한다. 둘째, 장애인운동이 대중적 운동으로서 광범위한 조직을 형성하기 위해서는 운동조직이나 운동단체간의 연계체계가 구축되어야 한다. 셋째, 장애인과 비장애인 모두가 장애문제의 해결에 적극적으로 동참하기 위해 장애인운동의 방식과 전략에 있어서 전체적인 전환이 필요하다는 과제를 설정할 수 있었다. The purpose of this study is to consider the development process of the movements of the disabled in Korean and so explore the directions and future tasks of movement of the disabled in order to secure the human rights of the disabled. This study divided the historical development process of movements of the disabled into survival rights movement, labor rights movement, education rights movement, and mobility rights movement, and so examined the historical development process of each movements. The movements of the disabled have the following historical characteristics. First, the movements of the disabled had the positive aspect that the proposals of such movements were begun and realized by the participation and request of the disabled concerned. Second, the center of gravity was shifted from the focus on mild of the disabled to the problem of severe handicapped people's right and life. Third, there emerged the positive perspective that the approach to the disabled problem was gradually changed from the viewpoint of welfare to the viewpoint of human rights in a sense of values. Through these historical characteristics, this study discussed the tasks remaining for the continuous development of movements of the disabled(the progressive handicapped people movements). Such tasks are as follows. First, the popular basis of movements of the disabled should be ensured and strengthened. Second, in order that the movements of the disabled might form a wide range of organizations as the popular movement, the linkage system between movement organizations or movement groups should be constructed. Third, in order that both the disabled and non-handicapped people might participate together actively in solving the disabled problem, it is necessary to change entirely the methods and strategies of movements of the disabled.

Third, exercise attitudes had a positive influence on intention of exercise practice. It means that if exercise attitudes is more positive, intention of exercise practice would be higher. 국문초록 청소년의 체력통제소재와 운동태도 및 운동실천의도의 관계 인천대학교 교육대학원 체육교육전공 최 성 우 본 연구는 청소년의 체력통제소재가 운동에 대한 태도와 운동 실천에 어떤 영향을 주는지를 알아보기 위하여 실시되었다. 이러한 연구를 통하여 청소년의 운동참여를 촉진하고 운동실천 전략을 개발하는데 기초 자료를 제공하고자 하였다. 연구대상은 인천에 소재한 중학교를 모집단으로 각 지역교육청에서 1개씩의 학교를 목적표집(purposeful sampling)하여 각 학교당 중학교 3학년에 재학 중인 남학생 38명, 여학생 26명으로 총 320명을 연구대상으로 선정하였다. 배포된 설문지 중 313부를 회수하였으며, 이중 분석에 사용된 유효 표본수는 조사가 완료되어 수집된 자료 중에서 응답내용이 부실하거나 신뢰도가 떨어지는 12부를 제외한 총 301부를 분석 대상으로 하였다. 설문지는 체력통제소재 척도, 운동태도 척도, 운동실천의도 척도로 구성되었다. 수집된 자료는 Windows용 통계프로그램 SPSS 13.0 version을 이용하여 분석하였다. 연구에 포함된 모든 변인의 평균과 표준편차를 산출하였으며, 인구통계학적 변인에 따른 차이를 알아보기 위하여 일원변량분석(one-way ANOVA)을 실시하였다. 그리고 체력 통제소재의 3개 요인(내재성, 강력한 외인, 운)과 운동 태도 및 운동 실천의도와의 관련성을 알아보기 위해 중다회귀분석(multiple regression analysis) 검증을 실시하였다. 이상의 과정을 거쳐 나타난 본 연구의 주요 결과는 다음과 같다. 첫째, 체력 통제소재의 하위 요인인 내재성(β=.435)은 운동 태도에 정적(+) 영향을 미치고 있는 것으로 나타났다. 둘째, 체력 통제소재의 하위 요인인 내재성(β=.480)은 운동 실천의도에 정적(+) 영향을 미치고 있는 것으로 나타났다. 셋째, 운동 태도(β=.631)는 운동 실천의도에 정적(+) 영향을 미치고 있는 것으로 나타났다.

열연강판의 구멍확장성 및 인장성질에 미치는 미세조직의 영향

최성우 경북대학교 대학원 2010 국내석사

For car body design, a reliable prediction of material formability is required. Stretch-flangeability has become an especially important formability parameter in addition to tensile properties, particularly for complicated auto body parts or parts under heavy deformation conditions. Increased strengths create problems which are usually hidden in the application of lower strength steels. One of these problems is ductile fracture in heavy deformation conditions such as experienced in hub hole forming of automotive wheels. The hole expansion ratio of multiphase steel is strongly influenced by microstructures and their distribution. Therefore, failure behaviour by the stretch-flangeability analysis of this steel has to be described as a function of microstructure. The effect of cooling temperature on the mechanical properties of hot-rolled high strength steels was important. The low temperature coiling method using a 3 cooling pattern (555℃, 355℃, 255℃) after hot rolling was very effective for producing high strength steel with high stretch- flangeability. In this study, microscopic deformation behaviors during punching and following stretch-flangeforming were investigated using three types of sheets with ferrite/pearlite, bainite, and martensite in order to clarify how the microstructure affects the stretch-flange-formability and tensile properties. Major conclusions from experimental results in this study are derived as follows; (1) The low temperature coiling method using 350 ℃ controlled cooling pattern was very effective for producing bainite-bearing steel with high stretch-flangeability. (2) In case of coiling temperature at 500 ℃, the balance of ductility and stretch-flangeability was excellent that have ferrite-pearlite microstructure. (3) The analysis of the hardness of ferrite and martensite suggests that the difference in hardness is the dominant factor of the stretch-flangeability of the ferrite-martensite steel. (4) During hole-expanding, the micro-cracks propagate mostly along the phase interfaces in the ferrite-martensite steel sheets in the case of poor stretch-flangeability. (5) The existence of strain gradient induced by hole punching is considered to be one of the reason for the highest hole-expanding ratio of the bainite steel. (6) Deep cracking resistance in this process is important to improve the stretch-flangeability.
