The purpose of this study was to examine the relationship between antecedent variables and subjective career success. Also, this study focused to investigate a moderating effect of gender difference between varieties antecedent variables and career success. Data were collected from 315 white collar employees who have been employed more than 3 years. The result of this study showed that subjective career success was significantly explained by sex role identity, political behaviors, career planning, school ties and regional relation, supervisor support, networking, and person-job fit. Gender moderated the relationship between career planning, networking and career satisfaction. Based on these results, the implications and limitations of this study and the directions for future research were discussed. 본 연구의 목적은 주관적 경력성공에 영향을 미치는 다양한 요인을 알아보고, 성별에 의한 조절효과가 나타나는지를 검증하기 위한 것이다. 일반 사무직에 종사하는 315명으로부터 자료를 수집하여 분석하였다. 연구결과, 주관적 경력성공에 유의미한 영향을 미치는 변인은 성역할 정체감, 정치적 행동, 경력계획, 학연 및 지연, 상사의 지원, 비공식적 인간관계, 개인-직무 적합성으로 나타났다. 성별에 따른 조절효과는 경력계획과 비공식적 인간관계 변인에서만 나타났다. 마지막으로 본 연구의 의의와 제한점, 미래 연구에 대해 논의하였다.

The purpose of the current study was to investigate whether cognitive distortion would mediate the relationship between socially prescribed perfectionism and abnormal eating behavior, and if such mediating effect would differ depending on the level of thin-ideal internalization. A total sample of 217 female undergraduate students completed measures assessing for socially prescribed perfectionism, cognitive distortion, abnormal eating behavior and thin-ideal internalization. The data was analyzed using SPSS Macro. The main results were as follows. First, cognitive distortion had a full mediating effect on the relationship between socially prescribed perfectionism and abnormal eating behavior. Second, thin-ideal internalization moderated the association between socially prescribed perfectionism and cognitive distortion. That is, as thin-ideal internalization increased, the effect of socially prescribed perfectionism over cognitive distortion increased. Third, the moderated mediating model was supported in that the mediating effect of cognitive distortion on the relationship between socially prescribed perfectionism and abnormal eating behavior increased as thin-ideal internalization increased. Limitation and future directions were discussed. 본 연구는 여자 대학생을 대상으로 사회부과 완벽주의와 이상섭식행동의 관계에서 섭식관련 인지왜곡이 매개하는지, 마른 이상적 체형 내면화가 이러한 매개효과를 조절하는지 알아보기 위해 SPSS를 활용하여 조절된 매개모형을 분석하였다. 217명의 여자 대학생을 대상으로 사회부과 완벽주의, 섭식관련 인지왜곡, 이상섭식행동, 마른 이상적 체형의 내면화를 측정하였다. 그 결과, 첫째, 인지왜곡은 사회부과 완벽주의와 이상섭식행동 간의 관계를 완전 매개하였다. 둘째, 사회부과 완벽주의와 이상섭식행동의 관계에서 마른 이상적 체형의 내면화의 조절효과가 나타났다. 즉, 마른 이상적 체형에 대한 사회문화적 기준을 내면화할수록 사회부과 완벽주의가 이상섭식행동에 미치는 영향이 증가하였다. 셋째, 조절된 매개효과가 나타났는데, 마른 이상적 체형의 내면화 수준이 높은 사람은 사회부과 완벽주의 수준이 높을수록 인지왜곡을 발달시켜 이상섭식행동에 취약해지지만, 내면화 수준이 낮은 사람은 사회부과 완벽주의 수준이 높더라도 인지왜곡을 발달시키지 않아 이상섭식행동에 취약하지 않다는 것이다. 끝으로 본 연구의 의의, 제한점 및 후속연구를 위한 제언에 대해 논의하였다.

Female sexual function is highly complex and deeply influenced by hormonal and non-hormonal factors. As sexual dysfunction becomes a common and important problem for women of all ages with related quality of life issues, we need to understand more about the effect of sex steroid hormones in female sexual function. However, there are limited data about the correlation between the value of sex steroid hormones- testosterone, in particular-and female sexual function. In a certain type of female sexual dysfunction (FSD), hypoactive sexual desire disorder, for example, there is evidence that treatment with androgens or with estrogens is effective. To widen the therapeutic options of hormone replacement therapy in FSD, further research is needed as to the benefits and risks of hormonal treatments in both pre- and post-menopausal women. Although important unanswered questions still exist in hormonal treatment of FSD, new therapeutic strategies are being studied and many ongoing clinical trials are expecting favorable results leading to more successful treatment of FSD.

윤하나,Youngdong Yoo,서관용,Juneho In,김봉수 대한화학회 2012 Bulletin of the Korean Chemical Society Vol.33 No.9

This review covers recent developments in our group regarding the synthesis, characterization and applications of single-crystalline one-dimensional nanostructures based on a wide range of material systems including noble metals, metal silicides and metal germanides. For the single-crystalline one-dimensional nanostructures growth, we have employed chemical vapor transport approach without using any catalysts, capping reagents, and templates because of its simplicity and wide applicability. Au, Pd, and Pt nanowires are epitaxially grown on various substrates, in which the nanowires grow from seed crystals by the correlations of the geometry and orientation of seed crystals with those of as-grown nanowires. We also present the synthesis of numerous metal silicide and germanide 1D nanostructures. By simply varying reaction conditions, furthermore, nanowires of metastable phase, such as Fe5Si3 and Co3Si, and composition tuned cobalt silicides (CoSi, Co2Si, Co3Si) and iron germanides (Fe1.3Ge and Fe3Ge) nanowires are synthesized. Such developments can be utilized as advanced platforms or building blocks for a wide range of applications such as plasmonics, sensings, nanoelectronics, and spintronics.

Purpose: We examined the effect of stress on the pathophysiology of bladder stability in terms of enzyme levels, Rho-kinase, and bladder relaxation. Materials and Methods: A total of 48 female Sprague-Dawley rats were studied in scheduled stress environments for 7, 14, and 28 days; 24 rats were in the control group and 24 rats were in the test (stressed) group. Results: Estrogen decreased significantly whereas testosterone and dopamine increased significantly in the stress group (p<0.05). Rho-kinase was significantly increased in the rats exposed to stress stimuli for 14 days (p<0.05). Collagen types I and III in the bladder tissue were significantly higher in rats exposed to stress for 14 days and 28 days (collagen type I in the 14-day group, p<0.01; collagen type I in the 28-day group, p<0.05; collagen type III in the 14-day and 28-day groups, p<0.05). Voiding frequency increased significantly as the duration of stress exposure was prolonged, in addition to a significant decrease in volume per voiding (p<0.05). Conclusions: The changes observed in micturition pattern, factors that contribute to smooth muscle contraction, and relaxation in the female rat bladder support the hypothesis that stress affects bladder stability.

게이트키핑 이론의 재해석 : 뉴미디어 환경에서 큐레이션을 중심으로

윤하나,정정주 한국지역언론학회 2020 언론과학연구 Vol.20 No.3

With the development of information and communication technology, the popularity of traditional news media is decreasing, and news consumption is moving to new media platforms, such as social network services and messaging systems. Certain topics like social media, online journalism, and the multi-channelization of news are drawing attention, but discussions of the meaning of classical media theories in the new media environment are not enough. Therefore, this study aims to revisit gatekeeping theory through curation, which is a common practice of information delivery in the new media environment. Gatekeeping theory, which presupposes the scarcity of sources and channels, is somewhat shunned in accordance with the belief in a multi-channel environment that increases news accessibility. However, news consumers are actively consuming and reproducing news within their social networks, intervening in the practice of institutional-level gatekeeping and playing as another type of gatekeepers. This study focuses on the curation as a concrete form of gatekeeping of news inmates and theoretically looks at interactions between new media and mass media, new media and human actors, and human actors in the network. This comprehensive discussion could provide one direction for future research in online journalism. 정보통신 기술발달과 미디어환경의 변화에 따라 전통 언론매체인 종이신문과 텔레비전의 이용률은 감소하고, SNS 등 뉴미디어 플랫폼을 중심으로 한 뉴스 소비 경향이뚜렷해지고 있다. 소셜미디어, 온라인 저널리즘, 뉴스의 다채널화 등 저널리즘의 특정한 주제들이 주목받지만 고전적인 언론 모델이 새로운 매체 환경에서 지니는 의미에대한 논의는 미진한 상황이다. 본 연구는 이와 같은 문제의식을 바탕으로 저널리즘 연구의 대표적 이론인 게이트키핑을 뉴미디어의 보편적인 정보 전달 방식인 큐레이션을통해 재해석해보고자 한다. 소수의 정보원과 채널의 희소성을 상정하는 게이트키핑 이론은 뉴스 접근성을 높이는 다채널 환경에 대한 믿음을 기반으로 외면 받고 있는 것이사실이다. 그러나 뉴미디어 환경의 뉴스 수용자들은 자신의 네트워크 내에서 적극적으로 뉴스를 소비하고 재생산함으로써 제도권의 게이트키핑 실천에 개입하는 한편, 또다른 게이트키퍼의 역할을 수행하고 있다. 본 연구에서는 뉴스 수용자 게이트키핑의구체적인 실천 형식으로서의 큐레이션에 주목하고, 이를 가능하게 한 뉴미디어와 매스미디어, 뉴미디어와 인간 행위자, 그리고 네트워크 내 인간 행위자들 간 상호작용을이론적으로 살펴보았다. 이러한 통합적 논의를 통해 향후 온라인 저널리즘 연구에 하나의 방향성을 제시하고자 한다.

노년기 성교육의 필요성과 방안

윤하나 대한의사협회 2019 대한의사협회지 Vol.62 No.6

Major improvements in health care have allowed people in the modern era to lead longer, healthier, and more active lives. The current generation of over-60s are more active than previous generations at the same age. In South Korea, the elderly population (65 years of age or older) has grown to more than 14% of the general population, meaning that we are already in the era of an ‘aged society’ and are transitioning into a super-aged society. Therefore, health issues in the elderly population cannot be ignored, and should be adequately addressed as soon as possible. Sexual health has become an important issue in the elderly that cannot be neglected, according to studies on sexual attitudes and behavior in older adults. As the quality of health improves in the elderly population, requests for proper sexual education and sexual health-related services have become more common. This pattern of increased sexual activity, partially driven by pharmacological advances in the treatment of sexual dysfunction and hormonal replacement products, has also led to increases in drug use and sexually transmitted infections (STIs). Responses to sexual health and education issues for the elderly currently remain ill-structured, as the significance of these issues is often ignored, largely due to incorrect assumptions about sexuality and sexual health among the elderly. Stronger requirements should be implemented for properly structured education and management systems regarding awareness, risk perception, and preventive strategies for safe sex among the elderly population in Korea.
