Synthesis of 2,2-difluoro-1-arylethenylsilanes and their reactions

이서희,정인화 한국공업화학회 2018 한국공업화학회 연구논문 초록집 Vol.2018 No.0

2,2-Difluoro-1-arylethenylsilanes 3 are useful building blocks for the synthesis of gem-difluorinated alkenes. However, previous methods for the preparation of 3 have been quite limited. A simple and straight forward approach to compound 3 will be established by the palladium-catalyzed cross-coupling of the 2,2-difluoro-1-trialkylsilylethenyl tosylate 2 with arylboronic acids. Starting material 2 was prepared in 83% yield from the reaction of 2,2,2-trifluoroethyl tosylate 1 with 2.2 equiv of LDA in THF at -78 °C for 1 h, followed by treatment with 1.0 equiv of (t-butyl)dimethylsilyl chloride. The cross-coupling reaction of 2 with arylboronic acids in the presence of 10 mol% Pd₂(dba)₃, 20 mol% SPhos and 1.7 equiv of Cs₂CO₃ in dioxane : H₂O (10:1) at 100 °C for 3-10 hours provided the compounds 3 in good yields. Acylation of 3 with benzoyl chloride in presence of AlCl₃ afforded the addition products 4 in good yields. The scope and limitation of these reactions will be presented.

특수체육에서 질적 연구의 이론적 배경과 연구 질의 평가

이서희 한국융합학회 2021 한국융합학회논문지 Vol.12 No.5

본 연구는 질적 연구를 시작하는 초보 연구자들을 위해 질적 연구의 기본적인 배경 학적 이론과 방법의 틀을 제시하고, 특수체육에서 질적 연구의 질을 평가하는 기준을 제시하는 데 있다. 첫째, 질적 연구의 기본이 되는 인식론의 이해를 설명하였다. 둘째, 질적 연구에서 가장 많이 활용되는 자료 수집 방법론을 제시하였다. 셋째, 질적 연구에서 자 료 분석 방법과 타당성 확보의 근거를 제시하였다. 마지막으로, 특수체육 영역에서 활용되는 질적 연구 질의 평가 기준 을 제시하였다. 국 내외 특수체육 분야에서 질적 연구의 숫자는 계속 늘어나고 있고 그 중요성 또한 계속 강조되고 있 다. 질적 연구는 연구자들이 참여자들을 관찰, 이해, 분석 그리고 해석하는 과정을 요구하기 때문에 연구자의 역할은 대단히 중요하다. 따라서, 질적 연구를 처음 시작하는 연구자들은 질적 연구의 본질적인 이해와 연구 방법론의 습득이 요구된다. 또한, 지속적인 질적 연구의 질의 평가로 좀 더 깊이 있는 질적 연구의 결과물이 특수체육 분야에 적용돼야 할 것이다. The purposes of this paper were to provide the basic segments of qualitative research to assist the understanding of qualitative research and to provide implications of indicators (i.e., criteria) to determine the rigor of the qualitative research in the area of Adapted Physical Education (APE). This paper was divided into five sub-categories to facilitate understanding the qualitative research, which were (a) the epistemological stances, (b) the data collection methods (c) the data analysis (d) the trustworthiness and (e) the implications of Adapted Physical Activity Taxonomy (APAT) in APE. Qualitative researchers deliver their understanding of human experience and knowledge by means of text rather than number so their explanations and understanding tend be subjective and distinct from otherwise interpretaotherwise (Crotty, 1998; Pitney& Parker, 2009). Examining the rigor of qualitative research is therefore concerned due to the complexity of understanding of reality (Goodwin 2020; Zitomer & Goodwin, 2014). In the meantime the roles of qualitative research have been highlighted in educational research including the area of APE because qualitative research enables researchers to examine different voices of school members (e.g., students with and without disabilities parents teachers Goodwin ,2020; Hodge et al., 2019; Zitomer & Goodwin, 2014).

Stretching exercises are known to help improve joint range of motion and mobility, but the appropriate exercise duration is not clear. The purpose of this study was to compare the effect of stretching exercises for different durations on the Achilles tendon. This study was conducted on 24 healthy adult males and females. Active and passive dorsiflexion ranges of the ankle joint were measured using a smartphone application to investigate the effect of stretching exercises for different durations (15, 30, and 60s), and the pennation angle of the medial gastrocnemius muscle was measured using ultrasonography. Measurements were taken before, immediately after, and 5 and 10min after the stretching exercise. The active and passive dorsiflexion ranges and pennation angle significantly improved after stretching exercises for all tested durations. The active and passive dorsiflexion ranges measured immediately after the stretching exercise were significantly greater for the 30 and 60s durations than for 15s duration, with significantly decreased pennation angle the gains persisted even 5 and 10min after exercise. These results indicate that the stretching exercises for the Achilles tendon should be performed for more than 30s. This study provides useful information for clinical practice and research related to stretching exercises.

Sonia Delaunay was among the group of avantgarde artists drawn to Paris in the early part of this century who were exploring concepts of art that were felt to capture best the speed and me chanization of the modern world. She believed modernity-and her own attitude toward modern life-could be expressed through the primacy of color in art and the dynamic interplay of its dissonances and harmonies. The metaphysical implications Delauny felt inherent in this idea made it applicable to all surfaces, and she was compelled to transform the world around her according to it. She set up a dialogue between fine art and everyday objects and accompplished the transition from representation work to her color theory through her investigation in embroidery and collage. This study is for Sonia Delaunay`s field of work which is close to fine and applied arts. To study Sonia Delaunay`s work, I can find some points of her fashion designs. First, Simultaneous, which is to use collage techenics such as simultaneous and meterial to combinate variety meterial. Secund, Durability which is restoration of mordern fashion, eventhough her work is 60 years old still it is foward to the furture. Imitation of textile which is devdloped by her, always looks new and fresh. Third, The elements of Folklore. Her elements of Russia, it appears on variety colors. Sepecially contemporary colths has elements of folklore, we should use it and made it to suituble to contemporary fashion of our country. For the furture, we need more study how to apply pictorial meterial of art into fashion design.

『恩遊日記』에 드러난 申象岳의 科擧 체험

이서희 민족어문학회 2023 어문논집 Vol.- No.99

The present study aims to examine the appearance of provincial scholars taking the past civil service examinations and the scenery of the examination hall through ‘EunYoo-diary’ written by Shin Sang-ak(1713~1767). Additionally, purpose to identify the literary value of ‘EunYoo-diary’ EunYoo-diary is written by a provincial scholar ‘Shin Sang-ak’, who was a resident of Mungyeong(聞慶), Gyeongsangbuk-do, South Korea. He wrote this diary while preparing for and taking Civil Services Examination(生員 會試) at the age of 53 in 1765. He departed from Mungyeong on January 29th to travel to the Seoul City(Hanyang) for the exam, and passed the ‘小科’ on February 8th. After returning home, he spent time with his family and visited the tombs of his ancestors. He recorded his travels for approximately 130 days until May 10th. The copy held by Dongsan Library at Keimyung University is the only existing Manuscriptof the diary. During stay in Ban-chon(泮村), Shin Sang-ak did not travel for sightseeing, but he recorded where he visited and whom he met. He selected people to enter the examination hall with him, and they evaluated each other's writings and prepared for the Hak-lye-gang(學禮講). In addition, he described the discomfort he experienced financial problems and poor living conditions, the friction with the people he lived with honestly. Furthermore, through his diary, we can speculate on the state of the examination halls in the 18th century and we can take note of the change in traditional dress culture during the reign of King Yeongjo(英祖). Shin Sang-ak expressed the perspective of a provincial student who left for the examination. This study was able to specifically examine the characteristics and related customs of past examinations during the reign of King 英祖, moving beyond previous research and analysis. Through this, it was confirmed that ‘EunYoo-diary’ has value as a literature source material for ‘civil service examination diaries(科擧日記)’ in various aspects.
