The Effect of Sirtuin on age-related cerebrovascular alteration in microvessel By Ju Yeon Mun Doctor of Philosophy in Biomedical Science Graduate School of Kyung Hee University Advised by Dr. Chan Park With aging, structural and functional alters in the cerebrovascular system including microvessels. Microvessels are the main pathway that regulates cerebral blood flow (CBF) to brain tissue. Age-related cerebral microvascular alteration reduces CBF and interferes with the supply of oxygen and nutrients to brain tissue, increasing the vulnerability of the brain and the risk of cerebrovascular diseases. However, morphological alterations at the microvascular level are still limited. In this study, age-related cerebrovascular morphological alterations were analyzed at the microvessel level using a microvessel isolation method. At the microvascular level, increased morphological alterations into atrophic and string vessels as indicated by a decrease in vascular diameter, the total amount of protein and density decreased with aging. The decreased expression of endothelial homeostasis maintenance factors, eNOS and Tie2, demonstrated they play a role in the age-related morphological alterations in microvessels. Sirtuins have attracted attention in animal and clinical studies for their anti-aging properties involved in the regulation of cellular aging. Among the seven mammalian sirtuins, age-related alters in sirtuin 1 (SIRT1) and sirtuin 6 (SIRT6) expression are known to play an important role in vascular diseases. This study evaluated trends in SIRT1 and SIRT6 expression in aging through meta-analysis. SIRT6 showed a consistent tendency to decrease with aging, while the expression of SIRT1 showed differences between species and had inconsistent patterns. Considering these results and the limited study on SIRT1 and SIRT6 expression in the aging brain, this study aimed to evaluate their expression patterns in aging microvessels and ultimately mitigate cerebrovascular alterations by modulating their expressions. SIRT1 and SIRT6 expression was decreased in the microvessels of the aging brain. Quercetin, an inducer of SIRT1 and SIRT6, was used to evaluate the inhibitory effect of age-related cerebrovascular alterations by increasing SIRT1 and SIRT6 expression. Quercetin inhibited the decrease in CBF and morphological changes at the microvessel level as well as pial vessels in aging mice. Quercetin increased the expression of microvascular SIRT1 and SIRT6 in aging mice and also increased the expression of eNOS and Tie2. In addition, quercetin increased the expression of Claudin-5, one of the blood-brain barrier (BBB) tight junction proteins, which inhibited BBB disruption in aging mice. These results demonstrate that quercetin may be a potential therapeutic agent of vascular aging by inhibiting cerebrovascular alterations.

의뢰전 중재 방식과 성공 요인에 관한 초등학교 일반교사의 인식 연구

문주연 경인교육대학교 교육대학원 2010 국내석사

기질적, 환경적, 문화적 요인으로 인해 지도하기 힘든(difficult to teach) 학생이 일반교실 내에 배치되어있으며, 이런 학생에게 적절한 교육을 제공하기 위해서는 일반교육과 특수교육의 협력이 요구된다. 특히, 지도하기 힘든 학생의 학습능력 향상과 문제행동 감소를 위하여 일반교육과 특수교육을 아우르는 다분야팀을 통해 학생에게 적합한 교수 지도 및 학급 경영 방법을 일반교사에게 제공할 수 있는 학교 차원의 시스템적 지원인 의뢰전 중재가 필요하다. 이에 본 연구는 우리나라 교육 여건에 맞는 의뢰전 중재 모형 개발의 방향을 제시하고자 의뢰전 중재 방식의 선호도와 의뢰전 중재 수행의 필수적 요소에 대한 초등학교 일반교사의 인식을 알아보았다. 연구 대상은 인천지역의 초등학교 일반교사로 지역과 학생 수준을 고려하여 총 210부의 설문지가 배부되었으며 이중 194부가 분석 대상에 포함되었다. 설문지는 국내·외 문헌연구를 바탕으로 본 연구자가 직접 개발하였으며 예비 조사와 전문가 검증을 통해 수정·보완 되었고, 응답자의 배경 정보에 관련된 8개의 문항과 의뢰전 중재에 대한 15개의 문항으로 구성되었다. 조사 결과는 성별, 업무량, 경력, 학급수를 변인으로 하여 우선순위를 묻는 문항은 빈도와 반응 백분율로, 리커트 척도로 표시하는 문항은 평균과 표준편차로 나타냈고, 교차검증, 사후 검증의 방법이 사용되었다. 연구 결과 첫째, 일반교사의 50%는 의뢰전 중재 과정에서 특수교육과의 협력에 긍정적인 반응을 보였다. 그러나 몇몇 요소에서 일반교육의 주도적 경향이 뚜렷이 나타났으며 여성보다는 남성 교사, 저경력 교사보다는 고경력 교사에게 더 뚜렷이 나타났다. 또한 정보 제공 단계, 중재 선택 단계, 중재 수행 단계 중 정보 제공 단계에서 특수교육과의 협력이 가장 잘 이루어 질 것으로 예상되며, 중재의 선택 시에 일반교사의 권한은 충분히 존중되어야 한다. 둘째, 일반교사는 스스로 특수교육요구학생에 대한 지도 능력을 낮게 평가하며 중재팀에 특수교육요구학생을 의뢰할 의사는 갖고 있으나 중재팀의 구성원으로 참여하는 것에는 부정적이었다. 의뢰를 높이기 위한 요인으로 ‘교사의 의뢰전 중재의 효과에 대한 인식’과 ‘시간적 여유’가 중요 요인으로 꼽혔으며, 팀 참여를 촉진하기 위해서는 ‘교사의 능력 향상’과 ‘시간적 여유’, ‘교내 교직원의 정서적 지원’이 필요한 것으로 나타났다. 셋째, 일반교사는 의뢰전 중재 시 수행해야 하는 모든 행정적 요소에 대해 부정적인 인식을 갖고 있었고, 학교 차원에서 요구되는 의뢰전 중재의 행정적 요소에 대한 실현 가능성에 대해서도 미온적인 태도를 보였다. 이를 통해 일반교사들의 행정적 업무에 대한 부정적 인식을 알 수 있었다. 그러나 ‘교사들 간 협동적이며 평등한 관계의 의사소통 가능성'에 대해서는 약하게나마 긍정적인 태도를 보였다. 일반교사들은 학습영역 전문가나 사회복지사와 같은 일반교사 이외의 특정 교육전문가에 의한 지원을 원하고 있었으며, 남성보다는 여성이 의뢰전 중재의 전(全) 과정에 보다 적극적인 참여 의사도와 실현 가능성을 나타냈다. 이상의 연구 결과는 국내 의뢰전 중재에 관한 연구의 폭을 넓히고, 우리나라 교육 현실에 적합한 의뢰전 중재 모형 개발을 위한 기초 자료로서의 역할을 할 것이다. This study was conducted to examine elementary school teachers' preferences about approach in implementing prereferral intervention, and perception about success factors for implementation of prereferral intervention, so as to help propose a prereferral intervention model appropriate to the Korean educational environment. A total of 210 questionnaires were sent out to elementary teachers in Incheon, rural areas. Among the questionnaires, 194 were analyzed. The draft of the questionnaire was made by the present writer based on preceding studies. The draft was revised by experts after a pilot test. The questionnaire included eight questions about information of respondents and fifteen questions about prereferral intervention. The collected data was analyzed after it was grouped according to gender, work load, the term of experience and the scale of the school in which they work. The questions which demanded prioritization were analyzed in frequency and percentage. In the other items used from the likert scale, the average and the standard deviation were calculated. The result shows that 50% of respondents answered with positive views about collaboration between special education and regular education. In some responses, however, general teachers were found to try to take their leadership. These aspects appeared more obviously among male teachers and long term experienced teachers. Among three steps - gathering information, exploring possible interventions, and implementing - in the stage of gathering information it was expected that collaboration with special education was activated. When intervention is chosen, the opinions of the general teachers need to be respected. Second, more than half of the general teachers have low self-efficacy on difficult-to-teach students. And over 65% of general teachers intend to refer the students with special needs to a prereferral intervention team, but at the same time, they do not want to participate in the intervention team. The factors to activate referral were 'belief on effect of prereferral intervention' and 'enough time', and the factors for participation in the team were ‘enhancing teacher's ability’, ‘enough time’, and ‘emotional support from school staffs’. Third, the general teachers were negative about all work for implementing prereferral intervention. From that result, it was found that general teachers were tired of public affairs. But the respondents said that the communication between teachers with collaboration and equal relationships might be possible. The general teachers want support from the education specialist, like an academic area specialist or a social worker, but not a general teacher. The female teachers would participate in all prereferral intervention process more than male teachers. These results deem to help discuss about prereferral intervention with a border perspective, and make an appropriate prereferral intervention model for both the students and the teachers. Key words : elementary school teacher, integrated education, perception, prereferral intervention, school personnel

The main goal of this study was to develop a self-exploration career coaching program for elementary school students and to investigate the effect of the developed program on career recognition. We selected eleven students who participate in our self-exploration career program as experiment group; and eleven students who attend a weekend program at S learning center in Seosan, Choongnam province, as comparison group. Students in experiment group took 10 sessions of weekly 50-minute long self-exploration career coaching program. We used career recognition questionnaire developed by Korea Employment Service (2008) for elementary students and conducted pre-post test between experiment and comparison groups using Student’s t-test. Statistical analysis was performed using SPSS Statistics version 24.0. The result of our study showed that experiment group have statistically significant increases in career recognition compared to comparison group. We confirmed that there would be a positive effect on career recognition for elementary students when our self-exploration career coaching program was applied. One of our contributions in our study was to develop career coaching program and apply to the career education for elementary students. Since children start to make self-esteem and future career over years of elementary school and these years are very important period to develop self-identity in their adolescence, career education should be aimed to enhance their ability to decide what to do and what to choose by themselves. At the same time, it should cultivate their discernment to design their own happy life and achieve their own future which they can use their interests, characteristics, and traits. Therefore, we expect that our career coaching program can be applied as a useful tool to strengthen elementary students’ ability to discover their true value and understand their career selection criteria so that they can be a main player to decide their own career. 이 연구에서는 자기 탐색 진로코칭 프로그램을 구안하고 적용해 봄으로써 초등학생의 진로 인식에 미치는 효과를 검증해 보는데 그 목적을 두었다. 진로코칭 프로그램은 5단계의 코칭대화 프로세스 모형으로 구성되었다. 1단계는 관계 맺기로 코칭에 대한 내용을 안내하고 친밀감을 형성할 수 있는 내용으로 구성하였다. 2단계는 자기 탐색으로 자기 이해를 위해 성격과 흥미, 가치관 등을 파악하고 또래코칭을 활용해 자신의 상황, 환경 등을 점검하면서 또래와의 공감대를 형성할 수 있도록 하였다. 3단계는 정보탐색으로 미래사회와 미래직업 세계의 변화에 대한 내용을 바탕으로 다양한 예측을 통해 새로운 직업 만들기 등의 활동으로 구성하였다. 4단계는 목표설정 및 실행계획으로 자신의 흥미와 관련된 관심직업을 탐색하고 자신만의 관심직업 카드 북을 만들어 직업에 필요한 능력 등을 고려하여 실행해야 할 우선순위를 정해보고 비전을 작성하도록 하였다. 5단계는 실행 지지로 자신의 계획을 잘 실행할 수 있도록 또래의 지지와 응원을 통해 실천 의지를 다지도록 하였다. 이 프로그램은 충남 서산시에 위치한 S 학습센터에서 운영하는 주말프로그램에 참여한 초등학생 22명을 대상으로, 실험집단 11명에게 매주 50분씩 10회기로 진로코칭 프로그램을 운영하였고, 비교집단 11명에게는 진로와 관련되지 않은 프로그램을 진행하여 실험집단과 비교집단 간의 진로 인식 효과를 비교·분석하였다. 통계처리는 SPSS Statistics 24.0 프로그램을 이용하였고, 유의수준 p<.05에서 t-검증을 하였다. 이와 같은 내용을 토대로 다음과 같은 결과를 얻게 되었다. 첫째, 자기 탐색 진로코칭 프로그램 적용은 초등학생의 진로 인식에 긍정적인 효과가 있는 것으로 나타났다. 실험집단의 진로 인식 효과를 하위척도별로 나누어 사전검사와 사후검사의 평균 차이를 살펴보았을 때, 진로 인식의 3가지 하위척도인 자기 이해, 직업 세계인식, 진로 태도에서 유의미한 차이가 있었다. 둘째, 실험집단이 비교집단보다 자기 이해에서 긍정적인 효과를 얻었다는 것이다. 실험집단의 자기 이해 척도의 하위영역 중 자기 탐색과 의사결정성향 수준은 유의수준에서 향상을 보였으며, 비교집단과도 유의한 차이를 보였다. 이것은 자신의 내면을 들여다보고 잠재적 가치를 발견함으로써 진로코칭에서의 핵심인 자기 이해에 대한 능력이 향상된 것으로 볼 수 있으며, 실행계획 세우기 활동은 자신을 이해하고 스스로 진로를 설계하고자 하는 동기부여 및 진로 태도가 향상되는 효과를 줄 수 있다는 것으로 여겨진다. 이러한 연구 결과로 자기 탐색 진로코칭 프로그램의 적용이 초등학생 각자의 가치를 발견하고 성장해 가는 것을 돕고, 진로코칭 프로그램에 참여하는 과정에서의 경험을 통해 앞으로의 진로에 적극적인 태도를 길러, 올바른 선택을 실현하는 행복한 개인으로 만족한 삶을 살 수 있도록 진로교육의 유용한 도구로 활용되기를 기대한다.

Dietary fat greatly influences milk fat properties, and physical stresses caused by high milking frequency would affect milk fat globules (MFG) stability associated with the level of free fatty acids (FFA). A high milking frequency leads to high level of free fatty acids, increasing the risk of rancid flavor in dairy products. Since automatic milking system (AMS) is on a gradual increase in Korea, this study was conducted to compare effects of the AMS and CMS(conventional milking system) on milk fat properties. Effects of protected fat feeding on milk fat properties were also observed. Four AMS and four CMS dairy farms were selected depending upon the milking system and feeding protected fat. Milk quality-related parameters such as milk fat globule size distribution, free fatty acid composition, and fatty acid composition were measured. Milking system did not have effects on milk composition as well as milk fat globule size. However, level of free fatty acid in raw milk was significantly higher (p<0.05) for daily 3 times milking compared with 2 times milking. The results demonstrated that increased milking frequency should be a factor contributing to the elevated levels of free fatty acid when using AMS. The average diameter of milk fat globule was affected by feeding of protected fat so that milk produced by cows given fat supplements contained milk fat globules with a larger average diameter and had an increased level of free fatty acid.
