Fabrication of conductive polymer combined with graphene oxide composites for lithium rechargeable cells

이희윤,김석 한국공업화학회 2015 한국공업화학회 연구논문 초록집 Vol.2015 No.1

In this present work, we introduced a PDDA coated on graphene oxide/ sulfur (PDDA-GO/S) composites for lithium-sulfur battery and demonstrate that conducting polymer coated on graphene oxide sheets can effectively induce chemical interaction of sulfur on the surface carbon framework and serves as a good electron conductive framework. The electrochemical performances of PDDA-GO/Sand RGO/S composites were investigated by using cycle voltammetry test measurement. Our investigation is that the PDDA-GO/S cathodes show excellent coulombic efficiency (>95%), cycling stability (60% retention within 100 cycle), and a good capacity of around 740 mAh g^-1 after 100 cycle.

기혼중년남성의 가족탄력성이 스트레스 대처행동에 미치는 영향

이희윤,박정윤 한국가족관계학회 2011 한국가족관계학회지 Vol.16 No.2

The purpose of this study was to examine the influence of married middle-aged men`s family resilience upon their stress coping behavior. The study subjects were 301 married middle-aged men between the ages of 40-54. The results were as follows. First, the extent of family resilience was above the middle level. Among the stress coping behavior, rational action presented the highest average score. Second, among the sub-variables of family resilience, the influential variables upon the coping behavior of stress were belief system`s family coherence, positive perspective, the flexibility of morality, religion and organizational pattern, connectivity, family resources, communication-oriented mutually cooperative problem-solving, clarity and emotional coping. There was significant difference in the coping behavior in response to stress by groups. When family resilience was higher, the men responded to stress rationally. Third, among the variables of family resilience, organizational pattern had the highest influence upon the coping behavior in response to stress, followed by belief system, communication and marriage status in that order. The groups of proper formation of family norm and proper reorganization of family structure, proper exchange of information within family circles and first-marriage coped with stress rationally.

Nutritional status assessed by the Controlling Nutritional Status (CONUT) score as a predictor of recurrence of urolithiasis

이희윤,강호원,김경,하윤석,김원태,김용준,윤석중,김원재,이상철 대한비뇨의학회 2021 Investigative and Clinical Urology Vol.62 No.5

Purpose: We aimed to determine the influence of nutritional status on urinary metabolic abnormalities and stone recurrence in patients with urolithiasis. Materials and Methods: We analyzed data for 464 stone-formers and 464 propensity-score-matched control patients that had been collected between 2003 and 2015. Nutritional status was evaluated by use of the Controlling Nutritional Status (CONUT) score, and patients were placed into two CONUT score categories (0–1 and ≥2). Serum and 24-hour urinary metabolites were evaluated in 464 stone-formers. Kaplan–Meier and multivariate Cox regression analyses were performed to assess the influence of nutritional status on stone recurrence. Stone recurrence was defined as radiographic appearance of new stones during the follow-up period. Results: Stone-formers showed a higher prevalence of poor nutrition (CONUT score ≥2) than did the propensity-score-matched control patients (p<0.001). Stone-formers who had poor nutritional status had significantly lower 24-hour urinary calcium but higher oxalate excretion (each p<0.05). Kaplan–Meier estimates demonstrated that stone-formers with poor nutritional status also experienced stone recurrence more rapidly (log-rank test, p=0.014). Multivariate Cox regression revealed that poor nutritional status was independently associated with stone recurrence (hazard ratio, 1.736; 95% confidence interval, 1.041–2.896; p=0.034). Conclusions: The CONUT score, an easily measured immunonutritional biomarker, is independently associated with a higher risk for stone recurrence in patients with urolithiasis. This implies that not only dietary excess, but also undernourished status, may be associated with aberrations in urine physicochemistry and stone recurrence.

견비통 환자에 대한 한방단독치료와 한.양방병행치료의 치료효과 비교 연구

이희윤,윤현민,김원일,Lee, Hee-Yoon,Youn, Hyoun-Min,Kim, Won-Il 대한약침학회 2008 Journal of pharmacopuncture Vol.11 No.2

Objectives This study is for comparing the results in two groups of using Oriental medical treatment only with using Oriental-Western medical treatment together to shoulder pain patients. Methods 49 shoulder pain patients who participated in the clinical study both at the Bukpyeoung Haemalkeun Oriental Medical Clinic and at the Bukpyeoung Medical Clinic in Donghae city were classified 2 groups. Group A was treated with Oriental medical therapy only and group B was treated with Oriental-Western medical treatment together. They have been treated 3 times a week for 4 weeks. Results After 1, 2 and 4 weeks of each treatment, the scores of the two groups in 'Subjective symptoms of shoulder pain', 'Indisposition index of every day life', 'Shoulder pain and disability index', 'Visual analog scale' became signific antly lower than those before treatment. Conclusion Treatment of group B was better than treatment of group A but, there was no significant difference in therapeutic action between two groups.

HPV Literacy as a Crucial Determinant for Completion of HPV Vaccine Series in Young Adult Women

이희윤,함영훈,이종욱 사회복지정책실천회 2020 사회복지정책과 실천 Vol.6 No.1

Objective: Human papillomavirus (HPV) and HPV-associated cancer are preventable with vaccination but relevant research on what factors are associated with HPV vaccination is limited, particularly among young adults. This study aims to identify how predisposing, enabling, and need factors of Andersen’s behavioral model are associated with HPV vaccine initiation and completion among young women residing in upper Midwest. Design: A cross-sectional survey was completed at the 2016 MN State Fair. Sample: A sample of 103 young women aged between 18-26 was analyzed. Measurement: The dependent variables were initiation and completion of HPV vaccine answered as binary values. Result: This study reported relatively low initiation (56%) and completion (47%) rates of HPV vaccination. The multiple logistic regression results revealed that having an annual check-up was associated with HPV vaccine initiation while HPV literacy was linked to HPV vaccine completion. Conclusion: Intervention strategies should target improving regular health check-ups and HPV literacy to promote vaccine completion.

합의적 질적분석을 활용한 동거 가치관에 관한 연구

이희윤,박정윤 한국가족치료학회 2017 가족과 가족치료 Vol.25 No.1

본 연구는 다양해진 가족생활 양식 중 하나인 동거생활을 살펴봄에 따라 미래가족을 예측하고자 했다. 따라서 동거자의 동거 가치관을 분석하였고, 이를 통해 동거가족의 삶을 좀 더 심층적으로 밝히고자 하였다. 연구대상의 특수성, 연구주제가 초보적 단계임을 고려하여 합의적 질적 분석(Consensual Qualitative Research)을 통해 동거자를 분석하였다. 남녀동거자 10명을 대상으로 심층면접을 실시하였으며, 연구팀과 감수자가 연구과정에 함께 참여하여 연구자의 편견을 배제하고자 하였다. 본 연구를 통해 밝혀진 동거자의 인식과 경험에 대한 주요 결과는 아래와 같다. 첫째, 참여자들의 동거 가치관을 살펴보면, 그들이 인식하는 동거의 정의는 연애의 과정이었으며, 동거생활의 전제조건은 사랑하는 관계, 생활을 유지할 수 있는 경제력으로 나타났다. 참여자들의 동거의 선택 동기는 파트너와 함께 있고 싶은 욕구, 경제적 부담완화, 심리적 요인, 데이트장소의 편의성이 도출되었다. Objectives: This study explored the possibility of cohabitation as one of the diverse family lifestyles in Korea. The researchers analyzed values of cohabitation expressed by individuals who are cohabitating and attempted to deepen understandings about the life of cohabiting families. Methods: Given the specificity of the study population and the paucity of research in this area in Korea, the Consensual Qualitative Research (CQR) method was utilized. Ten male & female cohabiters were interviewed in depth. A structured team and an auditor were used to guard against researcher bias. Results: The participants defined cohabitation as the due course of love. The prerequisite of cohabitation was found to be a loving relationship and financial capability to maintain living standards. The participants chose to live together for the following reasons: their desire to be with their partner, a reduction of financial burden, psychological factors, and the convenience for dating. Conclusions: This study extended the current research on cohabitation in Korea. To increase transferability, future studies need to use more diverse samples in terms of factors such as age and former marital experience.
