As the aviation industry looks to the future, fuel saving and $CO_2$ emission reduction play a dominant role in meeting the business challenges presented by global financial uncertainty. The IATA and International Government effort to save fuels, and then save 4 billion gallons of fuel burned, while reducing $CO_2$ emissions by 34 million tons. The various reduction methods adapted airlines and airports. We focused on optimized flight operation procedures for saving fuel and reduction emission cases. IATA and Canada government research reports focused on four methods that Engine Core Washing, Portable Water Management, Single Engine Taxi, APU limit operation. Apply to domestic airlines fuel data, Engine Core washing was saving more than Twenty-four thousand tons $CO_2$ emissions.

Objectives : A postoperative hydrocephalus is compromises the clinical outcome of patients with aneurysmal clippings as one of the major complications of SAH. Subdural hygroma is often complicated after aneurysmal clippings, which subsides spontaneously as simple hygroma, or progresses to shunt-dependent hydrocephalus (SDHC). To predict development of SDHC from the hygroma, and to improve clinical outcome of patients with aneurysmal clippings, we analyzed clinical predisposing factors between 2 subgroups, simple hygroma and SDHC. Patients and Methods : A retrospective study of 232 consecutive cases of clipped aneurysmal patient was undertaken in our hospital for last two years. The 46 patients(19.8%) developed hygromas after aneurysmal clippings. There were 22 cases with simple hygroma(9.5%), and 24 patients with SDHC(10.3%). Comparison of 2 subgroups was made for various clinical and radiological factors. Results : Older age(p=0.03), poor preoperative clinical grade(p=0.01), high Fisher grade(p=0.005), large amount of hygroma(p=0.014) and increased size of lateral ventricle ipsilateral to hygroma(p=0.001) were correlated significantly with SDHC. There was no statistical significance in sex, aneurysmal location and presence of acute preoperative ventricular dilatation between 2 subgroups. Conclusion : The clinical factors, such as older age, poor preoperative clinical grade, high Fisher grade, large amount of hygroma and increased size of lateral ventricle ipsilateral to hygroma showed statistical sinificance for differentiating SDHC from simple hygroma.

Hematomyelia is an extremely rare condition that cause severe neurological symptoms. We reported 4 cases of spontaneous hematomyelia, two cases of cavernous angioma and two cases of hematoma. In all patients, the clinical course was progressive ; motor and sensory abnormalities below the lesion and voiding difficulties were the common presenting symptom complex. The preoperative diagnosis was made by magnetic resonance imaging and the all patients underwent surgical exploration. Complete removal of hematoma was done in 3 patients and complete evacuation after aspiration of hematoma were performed in one patients. Neurological function did not worsen postoperatively in any patients. The early diagnosis with magnetic resonance imaging and immediate surgical treatment of the hematoma and the associated vascular malformation are considered to be the best way to halt the progression of the disease.

동양수련에서의 움직임을 통한 깨침의 심은 청정한 비움이며 무위로 여기에서 오묘한 이치가 나온다. 내단의 주천이 여기에서 비롯된다. 무위로서의 심은 마음 깨침의 본질이다 그래서 기공 수련에서 마음의 청정함을 이루는 정공을 중요시 하는 것 이다. 정공은 내관법으로 산란한 마음을 가라앉혀 숨의 기운이 생명의 자리인 성의 뿌리에 이르게 하며 이때 성과 신이 하나로 연결되어 주천의 깨침을 이루게 된다. 무심과 무위는 도의 근본으로 신의 작용이며 저절로 깨침이 이루어지는 것으로 성과 하늘이 하나로 통하게 된다. 무심은 내림의 작용으로 생명의 원기와 연결되며 이는 하늘의 숨이 생명의 불을 지펴 신명의 하늘이 되는 것이다. 이 신명의 기운은 몸 안을 깨워 기를 원활하게 소통시키며 몸 스스로의 움직임을 갖게 한다. 그것은 마치 무위의 움직임으로 어린아이들이 자연스럽게 노는 것처럼 몸 스스로 굳어있거나 불편한 곳을 찾아 움직임을 가지면서 몸을 가볍고 부드럽게 하여 신체를 원활하여야 한다. The substance of enlightenment though to movement in Oriental training is a pure empty, So the important reason is from here. And that is beginning of Jucheon from Naedan. As inaction is essence of enlightenment. So it is important to pure mind in Ki training. Jeonggong can make enlightenment of Jecheon through the mind control from breathe to root of Seong, Then Seong and Shin are connected. No-mind and No-action are root of Taoism. That is to act of Shin, and to be achieved of self-enlightenment, that Seong open onto sky. No-mind connect to energy of life with descensus. That become sky of Shinmyoung when breathe of sky makes a fire of life. The energy can awake inside of human body, that makes to be well ventilated with Ki. The body can have self-action. That likes children"s play, it"s natural action. So that find bad side on human body, finally it makes human body to soft and smooth.

자기성찰의 사회과교육적 실천 방안: "다시쓰기"를 중심으로

황정현 ( Jeong Hyun Hwang ),남상준 ( Sang Joon Nam ) 한국교원대학교 초등교육연구소 2012 초등교과교육연구 Vol.16 No.-

본 연구는 사회과교육에서 학습자의 주체적이고 능동적인 의미구성 과정의 중요한 양상으로서 ``자기성찰``을 제안하고, 이를 위한 사회과교육 실천방안을 모색하였다. ``자기성찰``은 ``대상``을 통하여 자기를 이해하는 일련의 사고행위를 가리키는 것으로, 대상의 의미를 탐색하는 과정을 통하여 자신을 되돌아보고 새롭게 발견·이해함으로써 세계와 자신의 삶에 대한 가치와 태도를 정향하는 의식활동이다. 사회과교육을 통한 ``자기성찰``은 학습자가 교과의 지식과 가치의 의미를 탐색하는 과정 속에서 그것이 나에게 가지는 상황적이고 맥락적인 의미를 구성함으로써 학습자 자신을 발견·이해하고 나아가 자기의 변화와 성숙을 도모할 수 있도록 해야 한다. 본 연구에서는 사회과 텍스트를 중심으로 한 교수-학습 상황에서의 자기성찰을 구현할 수 있는 하나의 실천방안으로 학습자와 사회과 텍스트의 만남과 대화를 통한 새로운 의미구성의 과정인 ``다시쓰기``를 제안하였다. 자기성찰을 위한 사회과교육 실천방안으로서 ``다시쓰기``의 가능성을 모색하고 다시쓰기가 이루어지는 읽기와 쓰기 국면, 그 결과물을 매개로 한 토의 국면에서의 자기성찰 전략을 제시해 보았다. Considering the perspectives of the individual development model which values the holistic growth of a learner through the social studies education, the study suggested the self-reflection as one of meaningful aspects in the process of the learner`s organizing a sense of subjectivity and activeness, which leads to the individual changes and full growth. The study considered the ``self-reflection`` a thinking behavior that a person understands himself through an ``object``. Here, the person is able to look back on himself and discovers new things as he searches for the meaning of the object. This way, the person refreshes himself with new values and attitudes towards the life. In other words, the meaning of the ``self-reflection`` through the social studies education indicates that it encourages the learners to achieve the individual changes and full growth as they build up any situational, contextual meanings which suit themselves in the process of their searching for knowledge and values that a subject possesses. As an action plan which realizes the self-reflection in the teaching-learning situation focused on the text of the social studies, the study came up with ``rewriting`` which is considered to be an organization of a new meaning, based on a meeting and a conversation between the learners and the text of the social studies.

교통노면표시는 교통안전을 위해 규제 또는 지시내용을 노면에 표시하여 전달하는 것으로, 노면표시 퇴색으로 인한 교통사고를 예방하기 위해 경찰청에서는 2014년 1월 1일부터 노면표시 반사성능 기준 2배정도 강화하였다. 본 연구에서는 강화된 기준에 따라 시공된 노면표시 반사성능이 시간이 경과함에 따라 저하되는 정도를 실제 측정하여 시간의 경과에 따른 노면표시 재도색 시기를 파 악하고, 노면표시가 퇴색됨에 따라 교통사고에 미치는 영향을 분석하였다. 그 결과, 노면표시 반사성능은 교통량 등은 외부 요인과는 관계가 없이 시간의 경과함에 따라 성능저하가 유의하게 나타났다. 단순 선형회귀분석 결과 백색 및 황색노면표시는 1주마다 각각 4.5, 2.4mcd/(㎡·Lux)의 반사성능이 저하되어 약 1년 후면 재도색 시기가 도래하는 것으로 나타났고, 노면표시 반사성능과 교통사고의 관계를 t-test로 검증한 결과, 200mcd/(㎡·Lux)이하일 경우 야간 교통사고 심각도가 증가가 통계적으로 유의한 것으로 분석된다.
