In this study, Q-methodology was applied to examine the recognition, values and attitudes of character leadership of childcare staff. The results of this study are as follows. The directors were shown to exhibit managerial character leadership, rational character leadership, emotional character leadership based on gratitude and love, and relational character leadership. The head teachers were shown to exhibit relation-oriented character leadership, stability-oriented character leadership that considered other teachers, efficiency- oriented character leadership to handle work efficiently, and system-oriented character leadership that led teachers into a community with a sense of responsibility. The general teachers were shown to exhibit belief-oriented character leadership to foster a sincere attitude as a teacher, fellowship- oriented character leadership to value their relationships with fellow teachers, value-oriented character leadership to value their current job as a childcare teacher, and child-oriented character leadership to value their relationship with children.

최경선,신혜경 한국코칭학회 2017 코칭연구 Vol.10 No.3

본 연구는 TREASURE Talk 코칭모델을 활용한 자율장학을 통해서 영유아 교사의 상호작 용 훈련효과를 확인하는데 그 목적이 있다. 이러한 목적을 달성하기 위한 연구문제로 영아반 교사, 유아반 교사의 TREASURE Talk 코칭모델을 활용한 자율장학의 상호작용 훈련효과는 어떠한지 살펴보았고, 연구도구 및 절차는 다음과 같다. 연구도구로는 이소희(2015)가 개발한 관찰을 통한 아동-성인 상호작용 코칭척도(CICAIO)를 사용하였고, 원내 자율장학이라는 특성 상 어린이집 5곳을 선정하고 원장 5명에게 TREASURE Talk FT 교육을 실시하였으며, 교사 40명이 자율장학에 참여하였다. 자율장학의 방법으로는 원내 교사교육과 각 교사를 대상으로 상호작용 관찰 및 지도 2회, 스크립트 제공 및 작성을 실시하였다. 자료분석 방법으로는 빈도 분석, t-검정에 의한 사전사후 검사를 실시하였다. 연구결과, 영아반 교사, 유아반 교사 모두에 게 TREASURE Talk 코칭모델을 활용한 자율장학의 상호작용 기술이 향상되었고, 교육훈련 효과가 있음이 나타났다. 따라서 어린이집 자율장학에 TREASURE Talk 코칭모델이 효과가 있는 도구로서 범용적으로 사용할 수 있음이 밝혀졌다.

늑대인간 전설의 흔적-다카기 도시오(高木敏雄), 1914 「人狼傳說の痕跡」 『鄕土硏究』 1-12-

Folk tales of Kim Hyun and Shin Dojing in Samgungnyusa are stories becoming a woman, a tiger had married a man. These stories remind us of the werewolf legend. The werewolf legend is the legend about the man that turned into the wolf, not necessarily be limited to the wolf and this belief is evident across the world. But werewolf legend was never mentioned in China, Chosun(Korea) and Japan. If looking about some of chinese legends, there is something that corresponds to werewolf legend. Also in japanese legends, there are stories that a man turned into the wolf. But these stories are supposed to come from the other region, be formed at the end of the Meiji Japan. Folk tales of Kim Hyun and Shin Dojing are difficult to be included in the werewolf legend. The story what after a woman put on a tiger skin, she became a tiger is rather similar to swan maiden legend. I'd prefer to reserve judgement on the origin of both tales for a while. 『三國遺事』의 김현과 신도징 설화는 호랑이가 사람이 되어 사람과 부부의 연을 맺는다는 이야기이다. 이 이야기는 서양의 늑대인간 전설을 연상케 한다는 점에서 주목된다. 늑대인간 전설은 늑대로 변한 인간에 대한 전설로 반드시 늑대로 한정되는 것은 아니며, 그 신앙은 전세계적으로 나타난다. 하지만 중국, 조선, 일본에서는 늑대인간 전설이 이야기된 바가 없었다. 중국의 전설 몇 가지를 보면, 인간이 호랑이로 변하는 이야기들이 있는데, 이 중에는 늑대인간 전설에 부합하는 것이 있다. 그리고 일본의 전설에는 사람이 늑대로 변하는 이야기들이 있다. 하지만 이 이야기들은 토착의 원시신앙으로부터 생겨난 것이 아니라 다른 지역으로부터 수입되어 메이지 말에 성립된 것으로 추정된다. 호랑이가 사람으로 변하여 사람과 부부가 되는 김현과 신도징 설화는 늑대인간 전설에 포함되기 어렵다. 오히려 호랑이 가죽을 입고서 호랑이가 된다는 이야기는 백조처녀 전설과 유사하다. 두 설화의 기원 문제는 당분간 보류해 두어야 할 것이다.

Proapoptotic Ginsenosides Compound K and Rh2 Enhance Fas-induced Cell Death of Human Astrocytoma Cells through Distinct Apoptotic Signaling Pathways

최경선,최철희 대한암학회 2009 Cancer Research and Treatment Vol.41 No.1

Purpose ; Malignant astrocytomas are among the commonest primary brain tumors and they have a grave prognosis, and so there is an urgent need to develop effective treatment. In this study, we investigated the molecular mechanisms that are responsible for the anti-tumor effect of ginsenosides on human astrocytoma cells. Materials and Methods ; We tested 13 different ginsenosides for their anti-tumor effect on human malignant astrocytoma cells in conjunction with Fas stimulation. In addition, the cell signaling pathways were explored by using pharmacological inhibitors and performing immunoblot analysis. DCF-DA staining and antioxidant experiments were performed to investigate the role of reactive oxygen species as one of the apoptosis-inducing mechanisms. Results ; Among the 13 different ginsenoside metabolites, compound K and Rh2 induced apoptotic cell death of the astrocytoma cells in a caspase- and p38 MAPK-dependent manner, yet the same treatment had no cytotoxic effect on the primary cultured human astrocytes. Combined treatment with ginsenosides and Fas ligand showed a synergistic cytotoxic effect, which was mediated by the reduction of intracellular reactive oxygen species. Conclusion ; These results suggest that ginsenoside metabolites in combination with Fas ligand may provide a new strategy to treat malignant astrocytomas, which are tumors that are quite resistant to conventional anti-cancer treatment.

반도체 광증폭기를 이용한 OR/NOR 다기능 전광 논리소자

최경선,전영민,박진우,변영태 한국물리학회 2008 새물리 Vol.56 No.6

An OR/NOR bi-functional all-optical logic gate has been constructed by using cross-gain modulation (XGM) in SOAs (semiconductor optical amplifiers). We have shown that the OR/NOR bi-functional all-optical logic gate operates well with RZ input signals at 10 Gbit/s. Only 2 SOAs and 1 circulator have been used to perform the OR/NOR bi-functional all-optical logic operation. 반도체 광증폭기 내의 교차이득변조 (XGM: Cross Gain Modulation)를 이용하여 OR와 NOR의 논리연산을 동시에 수행하는 다기능 전광 논리소자를 구성하였다. 다기능 전광 OR/NOR 논리소자는 RZ 입력신호로 10 Gbit/s 전송 하에서 동작 가능함을 증명하였다. 논리연산 OR와 NOR를 동시 수행하기 위해 오직 2개의 반도체 광증폭기와 1개의 광순환기를 사용하였다.

Background and Purpose Visual assessment of medial temporal-lobe atrophy (MTA) has been quick, reliable, and easy to apply in routine clinical practice. However, one of the limitations in visual assessments of MTA is the lack of widely accepted age-adjusted norms and cutoff scores for MTA for a diagnosis of Alzheimer’s disease (AD). This study aimed to determine the optimal cutoff score on a T1-weighted axial MTA Visual Rating Scale (VRS) for differentiating patients with AD from cognitively normal elderly people. Methods The 3,430 recruited subjects comprising 1,427 with no cognitive impairment (NC) and 2003 AD patients were divided into age ranges of 50–59, 60–69, 70–79, and 80–89 years. Of these, 446 participants (218 in the NC group and 228 in the AD group) were chosen by random sampling for inclusion in this study. Each decade age group included 57 individuals, with the exception of 47 subjects being included in the 80- to 89-year NC group. The scores on the T1-weighted axial MTA VRS were graded by two neurologists. The cutoff values were evaluated from the area under the receiver operating characteristic curve. Results The optimal axial MTA VRS cutoff score from discriminating AD from NC increased with age: it was ≥as ≥1, ≥2, and ≥3 in subjects aged 50–59, 60–69, 70–79, and 80–89 years, respectively (all p<0.001). Conclusions These results show that the optimal cutoff score on the axial MTA VRS for diagnosing of AD differed according to the decade age group. This information could be of practical usefulness in the clinical setting.

Objectives: The purpose of study is to investigate periodontal disease-related recognition and oral health-related behavior in orthodontic patients with fixed appliance. Methods: A self-reported questionnaire was completed by 286 orthodontic patients with fixed appliance in Gwangju, Jeonnam from September 1 to September 27, 2016. The questionnaire consisted of general characteristics (3 items), orthodontic related characteristics (3 items), knowledge of periodontal disease (3 items), and oral health-related behavior (4 items). The data were analyzed by frequency analysis, percentage and chi-square analysis using SPSS 21.0 program. Results: 62.8% had experiences of dental treatment and 67.5% had intention of involvement on incremental care program in orthodontic treatment periods. Accuracy rate of cause about periodontal disease was high in female and case of acquiring information experiences on periodontal disease (p<0.05). 67.2% performed correct toothbrushing for the management of periodontal disease in the experiences of acquiring information on periodontal disease in orthodontic treatment periods (p<0.05). The proportions of using interdental toothbrush and mouth rinsing solutions were high among those over 20 years old and students in the subjects (p<0.05). Conclusions:The accuracy rate were high in the answers about cause and management of periodontal disease in case of acquiring information experiences on periodontal disease in orthodontic treatment periods. Therefore, there is a need to further development and implementation of dental hygiene intervention program for periodontal disease care with fixed orthodontic appliances in that regard.
