부모의 지원, 성취압력과 초등학생 학업성취의 관계에서 학습동기 변인의 매개효과

신지연(Jiyoun Shin),권순구(Soon Koo Kwon),봉미미(Mimi Bong) 한국교육방법학회 2016 교육방법연구 Vol.28 No.3

이 연구에서는 초등학생이 주관적으로 지각하는 부모로부터의 지원과 성취압력이 그들의 학습동기와 전략 사용, 그리고 학업성취도를 어떻게 예측하는지를 조사하였다. 이를 위해 강원도 원주 소재 초등학교 6학년 학생 255명을 대상으로 설문을 실시하여 이에 대한 응답을 분석하였다. 이 때 학업성취도 지표로는 담임교사의 평정을 활용하였으며, 부모 변인과 학습동기 변인은 중간시험 이전에, 전략 사용과 학업성취도는 중간시험 이후에 측정하여 변인 간 예측관계의 타당성을 높이고자 하였 다. 구조방정식 모형 분석 결과, 부모의 지원과 성취압력 사이에는 부적 상관이 존재하였으며, 이들 부모 변인이 전략 사용과 학업성취에 이르는 경로는 학습동기 변인에 의해 유의하게 매개되었다. 예상과 달리, 부모의 지원뿐만 아니라 성취압력 역시 학습자의 자기효능감, 숙달접근목표, 수행접근목표를 정적으로 예측하였다. 숙달접근목표가 강한 학습자일수록 자기조절학습전략을 많이 사용하였고, 이는 다시 높은 학업성취도로 연결되었다. 반면 수행접근목표가 강한 학습자일수록 또 자기효능감이 낮은 학습자일수록 시험스트레스가 높았고, 시험스트레스가 높을수록 자기조절학습전략 사용이 감소하고 자기손상전략 사용이 증가하였다. 수행접근목표와 자기효능감은 시험스트레스와 자기조절학습전략 사용의 다중매개를 통해 학업성취도를 예측하였다. Survey responses of 255 elementary school students in Gangwon Province, Korea, were analyzed to see how their perceptions of parental support and achievement pressure predicted their motivation, strategy use, and achievement. Parental variables as well as student motivation variables such as self-efficacy, achievement goals, and test stress were assessed before midterm, while strategy use and teacher ratings of achievement were assessed after midterm. Structural equation modeling showed that motivation variables significantly mediated the relationship of parental variables with strategy use and achievement of students. Further, as mastery-approach goals became stronger, use of self-regulatory strategies increased, which resulted in higher achievement. As performance-approach goals became stronger and self-efficacy became weaker, students reported higher test stress. Higher test stress subsequently resulted in decreased use of self-regulatory strategies and increased use of self-handicapping strategies. Performance-approach goals and self-efficacy thus linked to achievement via test stress and self-regulatory strategy use as multiple mediators.

여성의학과 의료 서비스디자인 개선 연구

신지연(Shin, Jiyoun),조재경(Cho, Jaekyung) 인제대학교 디자인연구소 2013 Journal of Integrated Design Research (JIDR) Vol.12 No.3

최근 사회 전반에 걸쳐 서비스 산업의 비중이 높아지면서 의료서비스와 관련해서도 보다 환자를 배려하는 질높은 서비스와 진일보한 의료 환경에 대한 요구가 있었다. 보건 의료 분야에서도 디자인과 의료 서비스의 접점을 찾아 문제를 해결하려는 움직임이 있었고 디자이너의 시각에서 역량을 발휘하여 의료서비스의 여러 문제를 해결하고자 하고자 하는 다양한 시도가 나타나게 되었다. 따라서 여성의학과 병원의 경우에도 미용 관련 산업이나 산후조리원, 레스토랑 또는 카페 등의 외식업과 연계하여 여성의 심리적, 행동적 특성을 고려한 서비스를 제공하는 의료시설이 늘어났으나 이와는 별개로 정작 여성의학과와 관련된 치료나 시술을 자유롭고 떳떳하게 받을 수 없는 환경에 놓인 미혼 여성에 대한 배려는 매우 미약하다. 오늘날 우리 사회 젊은 층의 성의식이나 태도는 급격히 변화하고 있다. 특히 개방된 성 의식과 문화의 유입으로 기성세대와는 달리 성에 대해 자유로운 가치관과 태도를 지닌 사람이 많아졌다. 그러나 피임 교육과 임신, 출산에 대한 사회적 안전장치에 대한 논의와 적절한 대안은 제시되지 않은 채 여전히 과거에 머물러 있다. 본 연구에서는 여성이 여성의학과 병원에 내원하여 진료를 받는 과정에서 발생하는 심리적 장애요인을 구체적으로 확인하기 위하여 관찰 및 심층 인터뷰를 수행한 후 서비스 이용 단계에 따라 환자 여정 맵을 제작하였다. 그 결과 환자가 서비스의 전 과정에 걸쳐 사생활의 침해에 따른 불편함을 느끼는 것을 확인 할 수 있었고 특히 다른 환자의 시선이 불편하게 느껴지거나 의료진이 환자에 대해 공감하고 배려하는 정도가 낮은 데서 오는 불쾌함을 토로한 환자가 많아 심리적인 장애 요인이 분명히 작용하고 있다는 것을 확인 할 수 있었다. 본 연구는 여성의 눈높이에서 진행되는 연구를 통해 임신 및 출산을 목적으로 병원을 방문하는 환자는 물론 전 연령의 여성 환자의 편의 향상에 그 궁극적 목적이 있다. 또한 디자이너의 활동 무대가 단지 제품이나 광고 등 상업적 이익 창출에만 머무르지 않고 보건의료 분야의 문제를 다루고 나아가서는 사회적 차원의 문제를 해결하는데 보다 표준화된 디자인 방법과 도구를 활용하여 기여함으로써 공공의 이익과 사회 전반에 걸친 서비스의 질적인 발전에 일조할 수 있을 것으로 사료된다. A variety of demands of high quality service for patients and advanced medical environments has been raised to medical services in along with the increasing proportion of service industry in the overall aspects of society. In the health and medical area, there was an attempt to solve problems by finding out a contact point between design and medical services, and also various attempts have been made to solve medical service problems from the perspective of designers. Accordingly, in case of obstetrics and gynecology, there are increasing number of medical facilities providing services reflecting women’s psychological and behavioral features in connection with beauty industry, postnatal care center and food service industry like restaurant and cafe. Besides, it is still very insufficient to consider single women who are not properly cared or treated in relation with obstetrics and gynecology. Social awareness on single women who had experiences in sexual discourse is still negative, and women suffering from diseases could not properly express their own disease which tends them to aggravate diseases. This study would like to examine various barriers in the use of actual services together with background in which patients would not use medical services in obstetrics and gynecology, and then attempts to find improvement measures to consider women by means of service designs. Through the study carried out from the perspective of women, this study aimed to improve convenience of all aged women as well as patients for pregnancy and child birth. And the activities of designers do not remain in commercial profits such as product or advertisement but could involve health and medical problems. Furthermore, it is also expected to contribute to quality development of services for public benefits and social benefits by providing standardized design method and tools to solve problems of social level.

Synthesis of Fused Polycyclic 1,4-Benzodiazepines via Metal-Free Cascade [5 + 2]/[2 + 2] Cycloadditions

Shin, Jinhwan,Lee, Jiyoun,Ko, Donguk,De, Nirupam,Yoo, Eun Jeong THE AMERICAN CHEMICAL SOCIETY 2017 ORGANIC LETTERS Vol.19 No.11

<P>A metal-catalyst-free, mild, and efficient synthetic protocol for polycyclic 1,4-benzodiazepines via cascade [5 + 2]/[2 + 2] cycloadditions between pyridinium zwitterions and arynes is reported. Mechanistic experiments revealed that pyridinium zwitterions act as 1,5-dipoles in [5 + 2] cycloadditions with arynes for the construction of 1,4-benzodiazepines, which further undergo [2 + 2] cycloaddition resulting in the one-pot formation of one CN bond and three CC bonds.</P>

Molecular Mechanism of Atopic Dermatitis Induction Following Sensitization and Challenge with 2,4-Dinitrochlorobenzene in Mouse Skin Tissue

JiYoun Kim,JaeHee Lee,SoJung Shin,AhRang Cho,Yong Heo 한국독성학회 2018 Toxicological Research Vol.34 No.1

Laboratory animal models have been developed to investigate preventive or therapeutic effect of medicinal products, or occurrence or progression mechanism of atopic dermatitis (AD), a pruritic and persistent inflammatory skin disease. The murine model with immunologic phenomena resembling human AD was introduced, which demonstrated skewedness toward predominance of type-2 helper T cell reactivity and pathophysiological changes similar as human AD following 2,4-dinitrochlorobenzene (DNCB) sensitization and challenge. Molecular mechanism on the DNCB-mediated AD was further evaluated. Skin tissues were collected from mice treated with DNCB, and each tissue was equally divided into two sections; one for protein and the other for mRNA analysis. Expression of filaggrin, an important protein for keratinocyte integrity, was evaluated through SDS-PAGE. Level of mRNA expression for cytokines was determined through semi-quantitative reverse transcriptase polymerase chain reaction. Expression of filaggrin protein was significantly enhanced in the mice treated with DNCB compared with the vehicle (acetone : olive oil = 4 : 1 mixture) treatment group or the normal group without any treatment. Level of tumor necrosis factor-alpha and interleukin-18 mRNA expression, cytokines involved in activity of type-1 helper T (TH1) cell, was significantly downregulated in the AD group compared with other control groups. These results suggest that suppression of TH1 cell-mediated immune response could be reflected into the skin tissue of mice treated with DNCB for AD induction, and disturbance of keratinocyte integrity might evoke a compensatory mechanism.

( Jiyoun Kim ),( Eunsurk Yi ),( Munhee Kim ),( Ahra Oh ),( Jongseob Shin ),( Namyoung Kim ) 융합연구학회 2020 융합연구학회지 Vol.4 No.2

Since 2015, Korea has been operating regional sports science centers in 10 cities across the country, and is pursuing a plan to systematically link athletes’ physical fitness through physical fitness measurements according to the athlete’s life cycle. For 243 elite athletes whose physical strength was measured by the Seoul Sports Science Center, the development direction of each sport type of the elite athletes in Seoul is analyzed through classification and grade. As a result of the study, in terms of basic physical strength, the difference in physical strength by sport type was significant in all items of muscle strength, muscular endurance, muscle power, cardiopulmonary endurance, agility, balance, and coordination except flexibility. As a result of analyzing the difference in the level of the physical strength factor according to the application of the fitness grade criteria for each sport type, the A type showed significantly higher differences in grip strength and back strength than the B and D types. It was significantly higher in sit-up than type A. Type B showed significantly higher physical endurance, muscle power, cardiopulmonary endurance, agility, coordination, and equilibrium compared to the A and D types, and D type showed higher physical strength level than the A type in cardiopulmonary endurance, agility, and balance. Based on the results of this study, it is considered necessary to compare the performance and physical strength of male high school students in Seoul and the characteristics of athletes by sport type to review the training method and improvement of the performance.

경사면 상승 보행 시 경사 각도가 중족지관절에 관여하는 근육들의 근활성도에 미치는 영향

김지연(Jiyoun Kim),김판권(Pankwon Kim),신충수(Choongsoo S. Shin) 대한기계학회 2018 대한기계학회 춘추학술대회 Vol.2018 No.12

3D musculoskeletal models with Metatarsophalangeal (MTP) joint has not been studied for uphill walking, though uphill walking is very demanding for MTP joint. We aimed to compare EMG activities of extensor digitorum longus (EDL) and flexor hallucis longus (FHL) between level and uphill walking. EMG data of four subjects were collected during level walking, 15° and 25° uphill walking. One-way ANOVA tests and post-hoc tests were performed (α= 0.05). The 1st peak activity of EDL (all p<0.05: 0° vs. 15°; 0° vs. 25°), 2nd peak activity of EDL (all p<0.05: 0° vs. 15°; 0° vs. 25°; 15° vs. 25°), 1st peak activity of FHL (all p<0.05: 0° vs. 15°; 0° vs. 25°; 15° vs. 25°) and 2nd peak activity of FHL (all p<0.05: 0° vs. 15°; 0° vs. 25°; 15° vs. 25°) were significantly different. The 2nd peak activity of EDL and FHL increased by 175% and 275% during 15° and 25° uphill walking, respectively, compared to the level walking. As the slope angle increases, more FHL strength is needed for toe flexor to obtain propulsion force at push-off phase. Our results suggest that maximum isometric force of MTP joint muscles in a musculoskeletal model should be increased to study biomechanics of uphill walking.
