김유나,정창우 한국스포츠학회 2024 한국스포츠학회지 Vol.22 No.1

요약본 연구는 코로나19(COVID-19) 확산 시기에 은퇴를 결정 한 대학 운동선수 출신 4명을 선정하여 그들이 경험한 갈등에 대해 이해하고 해석하여 의미를 도출하기 위해 실시한 연구이며, 연구 목적에 따라 초점 집단 인터뷰를 실시하여 얻은 결과는 다음과 같다. 첫째, 운동선수에게 팬데믹 현상은 정상적인 훈련이 이루어지지 못했기 때문에 선수들에게 많은 혼란스러움을 안겨주었고, 연이은 대회 개최 취소는 선수들에게 보다 큰 혼란을 야기 시킨 것으로 나타났다. 시기적으로 운동선수들이 동계 훈련 기간을 마치고 시즌을 앞두고 있었기 때문에 보다 심리적 허탈감이 컷을 것으로 생각되며, 이러한 허탈함이 지속되면 될수록 목표가 사라짐에 따라 상실감과 권태감 등을 느꼈던 것으로 나타났다. 둘째, 은퇴 결정 요인에 대해서는 시합의 부재와 수차례 여러 가지의 심리적 갈등을 경험하면서 그들은 불확실한 미래에 대한 걱정과 반복되는 무의미한 일상에 따른 것으로 나타났고, 세부적으로 시합취소로 인한 진로 및 기회의 문제, 사라진 목표와 기약 없는 기다림에 대한 두려움과 권태감, 두려움을 극복하기 위한 생각의 전환은 곧 다양한 심리적 갈등이 시작된 것으로 나타났다. 이와 같은 과정을 거쳐 은퇴를 결정 한 선수들은 새로운 사회에 적응하는 단계에서“사회적응”에 대한 갈등이 새롭게 나타났다. 그들은 새로운 사회에 적응하는 과정에서 평소 운동선수 생활하면서 고민하지 못했던 부분들을 고민하고 어려워 한 것으로 나타나 은퇴 전, 은퇴 후 선수들을 위한 교육이나 상담 프로그램의 보급 및 저변확대가 필요할 것으로 생각된다. AbstractThis study selected four former university athletes who decided to retire during the spread of COVID-19. This study was conducted to understand, interpret, and derive meaning from the conflicts they experienced. The results obtained through focus group interviews according to the purpose of the study are as follows. First, the pandemic phenomenon caused confusion for athletes, and the successive cancellations of competitions caused even greater confusion for athletes. Because the athletes had finished their winter training period and were preparing for the season, it was thought that they would have experienced a greater sense of psychological desolation. The longer this detachment continued, the more they felt a sense of loss and boredom as their goals disappeared. Second, regarding the factors determining retirement, problems with career paths and opportunities due to competition cancellation, fear and boredom about lost goals and endless waiting, and a change in thinking to overcome fear were found to be the beginning of various psychological conflicts. Athletes who decided to retire after going through this process experienced new conflicts about “social adaptation” during the stage of adapting to a new society. Accordingly, it is believed that it is necessary to disseminate and expand the base of education and counseling programs for athletes before and after retirement.

This study examines the trend of research on outdoor play for infants and toddlers. For this purpose, a total of 221 papers related to outdoor play published in the past 10 years were analyzed. Focusing on the studies included in 55 degree papers and 166 academic journals conducted in Korea from 2012 to 2021. The collected papers were systematically analyzed by research topics, subjects, research types, data collection methods and publication years. The most commonly found research topics were teaching and learning method, followed by papers related to the operation status and recognition of outdoor play and activation methods. The research subjects of outdoor play-related papers were found to be infants, teachers, infants, parents, physical objects, literature subjects, and directors by overlapping the research subjects in one paper. In terms of research methods, observation was the most utilized, followed by the questionnaires. Based on the results of these studies, the development direction of research related to outdoor play for infants and toddlers was discussed and suggested.

Complementary electrochromic windows with conductive nano-composite thin films

김유나,김은경 한국물리학회 2008 Current Applied Physics Vol.8 No.6

All-solid-state electrochromic windows which have complementary color transition were assembled by employing poly(aniline-Nbutylsulfonate) s (PANBS), photo polymerizable electrolyte and poly(3,4-ethylenedioxythiophene) (PEDOT) in sequence. Each electrochromic layer thickness was controlled in nano-scale in order to balance charges between the electrodes generated from the electroactive layers. The electrochromic (EC) properties were characterized using cyclic voltammetry, chronocoulometry and UV–Vis spectroscopy. Absorbance change and coloration efficiency were dependant on charge density and an all solid state EC display based on an optimized thickness showed EC response at 2.4 V within 5 s with a stable memory effect.

Objective: To evaluate tumor responses in patients treated with anti-angiogenic agents for non-small cell lung cancer (NSCLC) by assessing intratumoral changes using a dual-energy CT (DECT) (based on Choi’s criteria) and to compare it to traditional Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Materials and Methods: Ten NSCLC patients treated with bevacizumab underwent DECT. Tumor responses to anti-angiogenic therapy were assessed and compared with the baseline CT results using both RECIST (size changes only) and Choi’s criteria (reflecting net tumor enhancement). Kappa statistics was used to evaluate agreements between tumor responses assessed by RECIST and Choi’s criteria. Results: The weighted κ value for the comparison of tumor responses between the RECIST and Choi’s criteria was 0.72. Of 31 target lesions (21 solid nodules, 8 lymph nodes, and two ground-glass opacity nodules [GGNs]), five lesions (16%) showed discordant responses between RECIST and Choi’s criteria. Iodine-enhanced images allowed for a distinction between tumor enhancement and hemorrhagic response (detected in 14% [4 of 29, excluding GGNs] of target lesions on virtual nonenhanced images). Conclusion: DECT may serve as a useful tool for response evaluation after anti-angiogenic treatment in NSCLC patients by providing information on the net enhancement of target lesions without obtaining non-enhanced images.

S-175 : Case of Pheochromocytoma Presenting with Combined Cardiovascular Manifestations

김유나,유철웅 대한내과학회 2013 대한내과학회 추계학술대회 Vol.2013 No.1

Excess level of catecholamine in pheochromocytoma can cause various clinical manifestations. Hypertension, palpitation, anxiety, headache and nausea are common manifestations of pheochromocytoma ever reported. There are few reports of pheochromocytoma presented with catecholamine-induced myopathy after mild stress and the case of the disease relating non-occlusive stroke is more uncommon.We report a case of pheochromocytoma manifestated repeated stress-induced cardiomyopathy after mild stress featuring fulminant myocarditis and combined non-occlusive stroke. A 56-year-old man admitted presenting with cardiac enzyme elevation, regional left ventricular (LV) wall motion abnormality and pulmonary edema. However, coronary angiography was normal. LV function was totally recovered at discharge, suggesting fulminant myocarditis. During the hospital stay, he also developed acute non-occlusive stroke but resulted in no neurologic sequelae. After 3 years, he readmitted because ventricular tachycardia and severe LV systolic dysfunction (EF=15%) were developed after mild stress. 3 days of applying percutaneous cardiopulmonary bypass system, the patient was completely recovered. Suspicious of pheochromocytoma, considering the repeated cardiomyopathy developed after stress, we checked 24 hour urine VMA and metanephrine and abdomen computed tomography, which revealed pheochromocytoma. After laparoscopic adrenalectomy, 24-hour urine catecholamine level were normalized and he was finally diagnosed with catecholamine-induced cardiomyopathy due to pheochromocytoma.

Background: While smoking prevalence in Korean men has been decreasing, it is increasing in Korean women. Little is known about women's smoking inequalities in Korea. This study was conducted to investigate the association of socioeconomic indicators with the initiation and cessation of smoking among Korean women. Methods: This was a cross-sectional study on 9,089 women aged 25-64 years from the 2008 Seoul Community Health Survey. The data on smoking and socioeconomic status were obtained through face-to-face interviews. Smoking initiation rate was defined as the proportion of the individuals who had started smoking at least one cigarette among all subjects. Smoking cessation rate was calculated by dividing the number of individuals who had quit smoking by the number of ever smokers. Education level, total family income and occupation were investigated as socioeconomic indicators. Results: Education level was significantly associated with both initiation and cessation of smoking. Lower educated women had a higher likelihood of smoking initiation (odds ratio [OR], 1.72; 95% confidence interval [CI], 1.17 to 2.51) but lower likelihood of smoking cessation (OR, 0.38; 95% CI, 0.22 to 0.66) than higher educated women. Smoking initiation rate was higher in manual workers (OR, 1.65; 95% CI, 1.20 to 2.27) than in non-manual workers. However, there were no significant differences of both initiation and cessation of smoking according to total household income. Conclusion: This study shows that there are smoking inequalities among Korean women. It is thought that education level and occupation are important determinants of women's smoking status.
