AlN films with c-axis orientation and thermal conductivity characteristics were deposited by using Pulsed Laser Deposition and the films were characterized by changing the deposition conditions. In particular, we investigated the optimal conditions for the application of a heat sinking plane AlN thin film. Epitaxial AlN films were deposited on sapphire ($c-Al_2O_3$) single crystals by pulsed laser deposition (PLD) with an AlN target. AlN films were deposited at a fixed pressure of $2{\times}10^{-5}$ Torr, while the substrate temperature was varied from 500 to $700^{\circ}C$. According to the experimental results of the growth temperature of the thin film, AlN thin films were confirmed with a highly c-axis orientation, maximum grain size, and high thermal conductivity at $650^{\circ}C$. The thermal conductivity of the AlN thin film was found to increase compared to bulk AlN near the band gap value of 6.2 eV.

한국산 팥꽃나무과에 속하는 5속 9종(팥꽃나무속: 4종, 아마풀속: 1종, 삼지닥나무속: 1종, 피뿌리풀속: 1종, 산닥나무속: 2종)의 잎의 해부학적인 두 가지 형질(중륵 횡단면, 엽병 횡단면)을 광학현미경과 전자주사현미경으로 연구하였다. 잎의 중륵의 외형은 3개의 유형 즉, 주맥부의 돌출 양상에 따라 상측이 '평평한 유형', '함몰된 유형', 혹은 '돌출된 유형'으로 구분되었다. 엽병횡당면의 윤곽은 대부분은 반달형이거나 원형으로 분류군마다 다소 차이가 있었고, 날개가 뚜렷하거나 미약하게 발달한 유형, 혹은 날개가 없는 유형으로 구별되었다. 유관속조직, 표피상납질, 결정체, 탄닌 등, 추가적인 해부학적 형질에 대해 상세히 기재하였다. 끝으로 조사된 잎의 해부학적 형질이 한국산 팥꽃나무과 분류군의 동정에 유용한가에 대하여 검토하였다. Two anatomical features of leaves, transverse section of midribs and petioles, were examined for nine species of five genera of Thymelaeaceae, Daphne L. -4 spp., Diarthron Turcz. -1 sp., Edgeworthia Meisn. -1 sp., Stellera L. -1 sp., Wikstroemia Endl. -2 sp., using light microscopy and scanning electron microscopy. In terms of shape of upper side, three types were observed, i.e., flattened, depressed, and raised. Outline of petioles is mostly semi-circular or circular in transverse section, with two distinct wings/weakly developed wings or without wings. Other characters besides anatomical features of leaves such as vascular bundle tissues, crystal, tannin are also described in details. Finally, we briefly discussed the systematic significance of the anatomical features of leaves for identification of Korean Thymelaeaceae.

Severities of musculoskeletal diseases (MSDs) have been recognized at the regular work such as manufacturing but incidence of MSDs are increasing also at the atypical work. The examples of those are health medical workers, office workers and service workers etc. Nurses among health medical workers are accomplishing to manage and recover the patients' health in the first place. Therefore, they are exposed to very stressful work conditions during caring the patients. This study was performed to analyze the musculoskeletal burdened work among nurses at a university hospital, in order to grasp the realities of the MSDs, analyze and prevent MSDs. We surveyed risk factors for ward, intensive care unit, delivery room, newborn room, operation room, function test room and central supply room at a university hospital in Seoul. It was executed for 2 months as the field study that was composed of simulation, real measurement, work motion assessment and subjective assessment. And the results were analyzed into ergonomics techniques. Works according to the criteria of musculoskeletal burdened work by the Ministry of Labor were scrub in operation room and heart ultrasonic function test. And a lot of works that need attention and management were also detected. So it should be required the education and systematic managements of MSDs for nurses.

중국 귀주성(貴州省) 준의(遵义) 차문화 고찰

정은희(Eun-hee Jung) 국제차문화학회 2019 차문화ㆍ산업학 Vol.46 No.-

중국 귀주성 준의시는 깊은 역사 속에 다채로운 차문화를 간직하고 있다. 이 글에서는 준의의 자연과 인문환경을 고찰하고, 차문화를 시대별, 지역별로 분석하여 차문화 특성을 분석한다. 첫째, 준의의 차문화는 자연문화이다. 천혜의 자연환경에서 자란 준의는 국가급 우량 차 산지로서 독특한 향미를 지니고 있다. 둘째, 소수민족의 문화이다. 준의에 살고 있는 30여 민족들은 그들의 일상식과 의례·사교 등 생활 속에 차가 함께 하며 다채로운 문화를 형성하고 있다. 셋째, 해독(解毒)문화다. 든든하면서도 소화하기 쉬운 유차는 아편 해독과 치료에 도움을 주었다. 넷째, 다방문화이다. 고진에는 차를 거래하고 보관하는 다방(茶帮), 차를 저장한 다고(茶庫)가 설치되었고, 상인들이 잠시 쉬거나 거래를 위한 찻집이 흥성하였다. 다섯째, 풍류문화이다. 황정견, 막우지 등 선인들은 준의의 차를 마시며 계절과 산수의 아름다움, 그리움 등을 읊은 아회를 즐겼다. 여섯째, 준의의 차문화에는 시대적 특징이 담겨있다. 중국의 서남 변방에 위치한 준의는 차마고도, 염다고도와 연관된 차문화가 발달했으며, 현대에도 차 산지 생태관광, 레저와 건강을 위한 차 여행지로 알려져 있다. 깊은 역사만큼이나 차문화가 풍부한 준의는 과거에서 의미를 발견하고 문화로 공유하는 과정을 통해 차문화를 전승하고 있다.

삶의 총체적 변화로 이어지는 평생학습 - 성인대학원생들의 학습과 변화를 중심으로 -

정은희(Jung Eun-Hee) 한국평생교육학회 2005 평생교육학연구 Vol.11 No.3

본 논문의 목적은 평생교육에 참여하는 학습자들이 과연 학습을 어떻게 이해하고 있으며 평생 학습의 의미를 어떻게 부여해 가는지에 대한 사실적 접근을 통해 평생교육관점을 새롭게 제시하고자 하는 것이다. 이러한 연구를 위해 실제 평생교육의 장면으로 선택한 곳은 대학원이고, 수업 참여 및 학습자와의 면접 등의 자료 분석을 통한 질적 연구로 진행되었다. 그 결과, 평생교육을 ‘삶의 총체적 변화를 추구하는 학습’의 관점으로 제시하게 되었다. 성인대학원생들은 대학원학습을 통해 각자 다양한 삶의 변화를 경험하게 되었는데, 그 과정은 지각의 단계, 반성적 탐색 단계, 실천 단계로 구분될 수 있었다. 그리고 이들은 각 변화를 실천하는 과정에서 촉진 혹은 방해의 요소들을 만나게 된다. 이렇게 성인대학원생들은 대학원에서의 학습을 통해 스스로 변화 필요성을 인식하고, 변화를 위한 실천의지를 가지게 되었으며, 이를 구체적으로 실천하기도 하였다. 이것을 통해 학습자가 자신의 삶의 의미를 새롭게 부여해가고 삶의 태도 변화를 경험하게 되었으며 결국, 학습자들의 증언을 통해 학습이 삶의 총체적 변화를 경험하도록 하는 중요한 통로가 됨을 확인할 수 있다. The purpose of this study was to look into how learners who received lifelong education perceived learning and how much they found lifelong learning meaningful in an effort to see lifelong education in a new light. The subjects in this study were graduate students who took lifelong education, and qualitative approach was taken by attending their classes and interviewing them. As a result, lifelong education was defined as learning in pursuit of holistic change in life. The adult graduate students investigated underwent a change in their lives by taking the graduate course. Their change was implemented in three stages: perceiving, reflective exploring and acting, and there were both facilitative and interruptive factors they faced in the course of changing. Thus, receiving graduate school education served as an opportunity for them to feel the need for a change, to have a will to seek it, and to actually change themselves. That experience enabled the learners to look at the meaning of their lives from a new angle and to take a new attitude toward life. All the findings of the study suggested that learning made a great contribution to triggering holistic life changes.

This study aims to explore the longitudinal relationship between volunteer experience and depression trajectory using Latent Growth Curve Modeling and to examine wether it varies by age groups using Multi-group Structural Equation Modeling. A total of 14,145 individuals aged 20 and over who participated in the Korean Welfare Panel Study from 2006 to 2011 were included in the analysis. Age groups were divided into three: young (20-40 or less), middle-aged (40-60 or less), and old adults (60 and over). Main results are as follows. 1) On average, the level of depression decreased over the 6 years but the trajectory varied by age groups. Specifically, old adults started with the highest level of depression and declined relatively more slowly compared to other age groups. 2) Volunteer participation lowered depression level at the beginning of the study. However, the rate of change was not statistically significant, meaning that the difference between volunteers and none volunteers remained consistently. 3) The effects of volunteer participation on depression varied by age groups. That is, volunteers and none volunteers among young adults did not show any differences in depression trajectory, whereas the depression trajectories of middle-aged and old adults varied by volunteer experience. Volunteers in middle-aged were less depressive in the 1st year but the size of difference decreased over time. Volunteers in old adults were less depressive in the 1st year and the difference of depression level remained consistently. These findings indicate that volunteer experience is associated with lower levels of depression but the relationship varied by age groups. Based on the findings, practical implications for research and practice are discussed.
