Purpose: This study was conducted in order to investigate the effect on respiratory function, trunk control, and functional activities of daily living (ADL) through respiratory muscle strength training in patients with chronic stroke. Methods: Eighteen subjects who were six months post stroke participated in this study. The subjects were randomly allocated to two groups: experimental (n=10) and control (n=8). Both groups received physical therapy for five sessions, 30 minutes per week, during a period of six weeks. Subjects in the experimental group participated in an additional respiratory muscle strength training program, in which the threshold PEP device was used for 30 minutes per day, three days per week, during a period of six weeks. Results from pretest-posttest control were evaluated by pulmonary function forced vital capacity (FVC), forced expiratory volume at one second (FEV1), FEV1/FVC, peak expiratory flow (PEF), capacity of cough, trunk control, and functional ADL. Results: Significant improvement in the FEV1, PEF of pulmonary function (p<0.05), cough function (p<0.05), and trunk control (p<0.05) was observed among the groups. Conclusion: Respiratory muscle strength training improves pulmonary function, capacity of cough, and trunk control. These results suggest that respiratory muscle strength training is feasible and suitable for individuals with chronic stroke.

We demonstrate an 80km-reach 64-channel DWDM-PON based on wavelength-locked F-P LDs by changing the position of the C-band BLS for upstream channels from the CO to the RN. It mitigates the necessity of the high power C-band BLS and its handling problems. It also reduces back scattering induced penalty. We obtained less than $10^{-6}$ PLRs in all 128channels through 80km SMF. We also demonstrate a 240km-reach DWDM-PON based on wavelength-locked F-P LDs by adding a bidirectional erbium-doped fiber amplifier(EDFA). We show packet-loss-free transmission in all 128channels at 125 Mb/s per channel over 240km SMF We report the detuning effect of arrayed waveguide gratings(AWGs) and crosstalk effect in the implemented system. We Propose an architecture of a next generation defense wire communication system with the demonstrated long-reach DWDM-PON.

중심과 주변의 중층성: 노래와 평화기념공원으로 본 동아시아

김민환 ( Min Hwan Kim ) 한국사회사학회 2013 사회와 역사 Vol.0 No.97

이 글은 추상적이고 규범적이라는 평가를 받는 ``성찰적 동아시아론(reflective discourse on East Asia)``에게 구체성을 부여하고자 하는 시도 중 하나이다. 외관적으로 보면 전혀 관련없을것 같은 두 종류의 문화적 산물, 즉, 노래 세 곡과 평화기념공원 세 곳을 각각 의식적으로 ``분단된 동아시아``라는 맥락에 위치시켰을때 새로운 의미를 찾아낼 수 있었다. 「오키나와를 반환하라(沖繩を返せ)」, 「총통장공기념가(總統蔣公紀念歌)」, 「아름다운 강산」 등의 노래 세 곡은 모두 데땅트를 통해 동아시아 중심에서 냉전적 긴장이 감소될 때 오히려 냉전적 긴장이 배가되었던 동아시아 주변 사람들의 고통이 다른 방식으로 표현된 것들이다. 오키나와평화기념공원, 타이페이2·28평화기념공원, 제주4·3평화공원은 1990년대 초반 세계적인 탈냉전을 배경으로 진행된 동아시아 탈냉전의 산물이었다. 그러나 이시기 이루어진 탈냉전이 냉전과 분단의 완전한 해소가 아니었기 때문에, 이들 평화기념공원은 탈냉전을 지향하는 세력과 냉전적 사고를 고집하려는 세력의 전장이 되었다. 따라서 평화기념공원이 지향하는 ``평화``의 의미는 국민국가 내부의 투쟁 양상에 따라 매우 다르게 표상되었다. 그러나, 이들 세 평화기념공원을 분단된 동아시아라는 맥락에 위치시켜야만 ``발견``할 수 있는 평화에 대한 메시지가 따로 존재했다. 그것은 바로 동아시아에서 냉전에 기반한 분단의 완전한 해체와 새로운 동아시아질서의 형성에 폭력적 수단이 개입되는 것이 아니라 평화로운 방법이 동원되어야 한다는 ``평화``에 대한 비원(悲願)이었다. This paper attempts to substantialize the reflective discourse on East Asia, which is said to be rather abstract and normative. Two cultural products of songs and peace commemoration parks, seemingly unrelated, can provide new insights for this discourse, if they are contextualized in "divided East Asia." Three songs of "Return Okinawa(沖繩を返せ), Chiang Kai-shek Memorial Song(總統蔣公紀念歌), and Beautiful Land(아름다운 강산)" were respective representations of increased sufferings of people of East Asian periphery when the tensions of cold war in East Asian Center decreased. Three peace commemoration parks of Okinawa Peace Memorial Park, Taipei 228 Peace Memorial Park and (Jeju April 3rd Peace Park are the results of post-cold war in the context of global post-cold war from the early 1990``s. However, this post-cold war did not bring the compete resolution of cold war or division and peace commemoration parks became the battle grounds between the groups striving for post-cold war and groups maintaining cold war order. Therefore, the meaning of ``peace`` in such parks were differently represented according to the level of the struggles within each nation state. Nevertheless, there exists a message for ``peace``, which can be ``discovered`` only contextualized in divided East Asia. That is a yearning for ``peace`` of East Asia, that division based on cold war should be completely dismantled and the formation of order in East Asia should be not by means of violence but by peaceful means.

김민환(Kim Min Hwan),안관영(Ahn Kwan Young) 학습자중심교과교육학회 2012 학습자중심교과교육연구 Vol.12 No.1

이 연구는 학교장의 변혁적 리더십이 교사들의 임파원먼트에 미치는 효과와 두 변수간의 관계에서 재직기간의 조절효과를 실증적으로 분석한 것이다. 이에 따른 자 료를 2010년 3월 현재 강원 지역의 초등학교 교사 396명으로부터 설문지를 이용하여 수집하였다. 분석 결과 학교장의 카리스마와 개별적 배려 리더십은 각각 교사들의 자기 효능 감과 자율성 및 영향력 요인에 긍정적 영향을 미치고는 것으로 나타났다. 지적 자극 리더십은 교사들의 의미감과 자율성에, 그리고 고무적 리더십은 교사들의 의미감과 자율성 외에 영향력 요인에도 긍정적 영향을 미치는 것으로 분석되었다. 재직 기간은 학교장의 카리스마와 교사의 의미감의 관계에서, 지적 자극 리더십과 교사의 자율성 및 영향력의 관계에서, 그리고 고무적 리더십과 자기 효능감의 관계 에서 긍정적인 조절 효과를 갖는 것으로 나타났다. The purpose of this paper is to review the relationship between transformational leadership and teachers empowerment, and the moderating effect of tenure. In order to achieve this object, 396 questionnaires were gathered from primary school teachers in Kangwon province. To test hypotheses, this study used multiple regression analysis and hierarchical multiple regression analysis. The results of statistical analysis can be outlined as follows: Firstly, charisma is related positively with self-efficacy, self-determination, impact. Intellectual stimulation is related positively with meaning, self-determination. Individual consideration is related positively with self-efficacy, self-determination, impact. And inspirational leadership is related positively with meaning, self-determination, impact respectively. Secondly, in the moderating effect of gender and tenure on the relationship between transformational leadership and empowerment, it was found that transformational leadership(charisma, individual consideration, intellectual stimulation, and inspirational motivation) partly has effect on empowerment while interacting with teachers tenure.

This study has been conducted to investigate the status on the school curriculum construction and implementation at the primary and secondary school level, and to explore the tasks for its improvement. Data was obtained from 273 teachers surveys and 12 teacher interviews, and it was analyzed by percentile and F-test. Some of the research findings are as follows: First, most of the school curriculum committees do not operated practically. The bulk of the school curriculums were developed by only one curriculum researcher instead of cooperation with other teachers. Second, most of schools established the school curriculum from December to March every year, and its processes are too formal. Thus, in order to increase the effectiveness of the school curriculum usage, it is necessary to make the curriculum until February. Third, most of all schools collect teachers opinion about the curriculum construction and implementation to set up the school curriculum. However, their results are merely reflected for school curriculum construction. Instead, they refer to the former or other schools curriculums to make the new school curriculum. Fourth, teachers are not using the documents of school curriculum many times. They make use of it three to four times in a year for the sake of checking school schedules. Given those facts, following suggestions might be attempted. The school curriculum committees are necessary to be activated. Also, the school curriculum needs to be constructed by much more teachers than only one curriculum researcher. Furthermore, it is needs to make a best workable school curriculum that coincides with each school circumstances.

목적: 특발망막전막에서 수술 전후 빛간섭단층촬영으로 망막층별 두께를 측정하고 수술 후 시력예후와의 관계에 대해 알아보고자 하였다. 대상과 방법: 단안 특발망막전막 환자 46명, 46안을 대상으로 수술 전, 수술 후 1, 3, 6개월째 스펙트럼영역 빛간섭단층촬영기로 측정이 가능한 모든 망막층들의 두께를 측정하여 수술 전 대상군의 정상안과 비교하였고, 유리체절제술 후 6개월째 두께변화를 측정하여 각 인자들과 수술 후 시력예후와의 상관관계에 대해 알아보았다. 결과: 수술 전 정상안과 비교하여 망막신경섬유층의 두께가 가장 많이 증가하였으며, 시세포층과 망막색소상피층에서는 정상안에 비해 감소하였다. 수술 후 6개월째 망막층별 두께변화는 망막신경섬유층, 신경절세포층, 내망상층, 신경절세포-내망상층, 외망상층에서 감소하였고, 시세포층은 수술 전과 비교해 증가하였다. 수술 전 망막전막안과 정상안 간 신경절세포층의 두께차이(r=0.477, p=0.008)가 수술 후 최대교정시력과 유의한 상관관계를 보였다. 결론: 수술 전 망막전막안과 정상안 간 신경절세포층의 두께차이가 수술 후 최대교정시력과 유의한 상관관계를 보였고, 두께 차이가 클수록 수술 후 시력예후가 불량했다. Purpose: In this study, we evaluated the thickness of each retinal layer using spectral-domain optical coherence tomography (OCT) and investigated the correlation between the thickness of each retinal layer and postoperative visual acuity in eyes with idiopathic epiretinal membrane (ERM). Methods: his retrospective study included 46 eyes from 46 patients with idiopathic ERM who underwent pars plana vitrectomy. Each retinal layer thickness was measured by spectral-domain OCT before operation and at 1, 3, and 6 months after operation. The thickness of each retinal layer was evaluated in the control group before the operation. We performed an analysis of the changes in thickness of each retinal layer at 6 months after operation and then investigated the correlation between the retinal layer thickness and visual improvement. Results: Preoperatively, the thickness of the retinal nerve fiber layer (RNFL) in the ERM group showed more increased compared with that in the control group, and the thickness of photoreceptors and retinal pigment epithelium were decreased compared to those in the control group. At 6 months after the operation, thickness changes were reduced at the RNFL, ganglion cell layer (GCL), inner plexiform layer (IPL), GCL-IPL complex, and outer plexiform layer, while the photoreceptor layer increased compared with the values preoperatively. Differences in the preoperative thickness of GCL between the two groups had a significant correlation with postoperative visual acuity (r = 0.477, p = 0.008). Conclusions: Differences in preoperative thickness of the GCL between the two groups had a significant correlation with postoperative visual acuity. The greater was the thickness of the GCL, the worse was the visual outcome.
