김은혜,이광진,송국현,Kim, Eun-Hye,Lee, Kwang-Jin,Song, Kuk-Hyun 대한용접접합학회 2015 대한용접·접합학회지 Vol.33 No.2
This study was carried out to evaluate mechanical properties of the jointed Al6061/HT590 alloys by friction stir welding (FSW). FSW was conducted under the conditions with tool rotating speed of 500 RPM and traveling speed of 300 mm/min., where Ar gas was introduced to prevent the materials from corrosion during the welding process. Electron back-scattering diffraction (EBSD) was used to characterize microstructures such as grain size, misorientation angle and crystal orientation. Evolution of intermetallic compounds in Al6061 during the process were examined in terms of morphology, size and aspect ratio at three distinct zones Al base material, heat affected zone and stir zone, where transmission electron microscope (TEM) was used. It was revealed that FSW gave rise to refinement of grains as well as growth of intermetallic compounds in Al6061. The morphological changes of intermetallic compounds exerted an influence on mechanical properties, resulting in occurrence of fracture in the part of the base material instead of the jointed parts (heat affected zone and stir zone). This study systematically evaluated the microstructural evolutions during the FSW for joining Al6061 with HT590 and their effect on mechanical properties.

Objective: This study was aimed to report the therapeutic effects of herbal medicine on chemotherapy-induced peripheral neuropathy (CIPN). Methods: The prior studies were searched from the databases included PubMed, Cochrane Library, EMBASE, CNKi, CiNii, KISS, NDSL, KMBASE, and OASIS until September 2020. The main search keywords were chemotherapy, peripheral neuropathy, and herbal medicine, and only randomized controlled trials that analyzed the therapeutic efficacy of herbal medicine were included. The Cochrane's Risk of Bias was used for assessment of the risk of bias and the Review Manager 5.3 program was used for meta-analysis. Meta-analyses were grouped by the administration routes of herbal medicines (oral administration or topical use). Results: Nine studies with a total of 563 participants were included. Compared with usual care, the effective rate was higher in oral administrated herbal medicine (RR 1.67, 95% CI 1.25 to 2.23; p<0.001, I2=31%). In addition, topical herbal medicine showed an significantly higher effective rate than placebo (RR 2.20, 95% CI 1.52 to 3.18; p<0.001, I2=0%) and usual care (RR 2.24, 95% CI 1.74 to 2.89; p<0.001, I2=66%). There was no severe adverse effect in all participants. Conclusions: Herbal medicine appears to improve neuropathy caused by chemotherapy in cancer patients more than conventional therapy of CIPN. However, as there is heterogeneity between the included studies and a lack of blinding, further well-designed researches are more needed.

This study was carried out to evaluate the developed microstructures and mechanical properties of friction welded A6063 alloy. For this work, specimens were prepared at a size of 12 mm ${\O}{\times}80mm$, and friction welding was carried out at a rotation speed of 2,000 RPM, friction pressure of $12kgf/cm^2$ and upset pressure of $25kgf/cm^2$. To perform an analysis of the grain boundary characteristic distributions, such as the grain size, orientation and misorientation angle distributions, the electron back-scattering diffraction method was used. In addition, in order to identify the dispersed intermetallic compounds of the base and welded materials, transmission electron microscopy was used. The experimental results found that the application of friction welding on A6063 led to significant grain refinement of the welded zone relative to that of the base material. Besides this, intermetallic compounds such as AlMnSi and $Al_2Cu$ were found to be dispersed with more refined size relative to that of the base material. This formation retains the mechanical properties of the welds, which results in the fracture aspect at the base material zone. Therefore, based on the developed microstructures and mechanical properties, the application of friction welding on A6063 could be used to obtain a sound weld zone.

Objectives: This study was aimed to report a patient with metastatic pancreatic cancer treated with modified Bangam-tang and Gunchil-dan in conjunction with gemcitabine. There were better survival-related outcomes compared to gemcitabine alone. Methods: The patient with metastatic pancreatic cancer received gemcitabine as palliative chemotherapy since June 2016 concurrent with modified Bangam-tang and Gunchil-dan since October 2016 to October 2017. To evaluate the effect of treatment, tumor markers (carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA)), Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, and overall survival were checked. Adverse events were evaluated according to the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Results: After 12 months with the combination treatment, levels of CA19-9 were decreased from 8747 to 265.7 ng/ml and CEA from 42.2 to 6.5 U/ml. Clinical partial response state was shown until May 2, 2017 and stable disease state was maintained from August 4, 2017. In March 2018, the patient got an operation including pancreatectomy and diagnosed with no evidence of disease state in September, 2018. In conclusion, it showed the overall survival of 29 months from June, 2016 to November, 2018. Serious adverse events were not identified. Conclusions: This study suggested that combined treatment with modified Bangam-tang and Gunchil-dan may show better outcome in patient with metastatic pancreatic cancer than gemcitabine alone.

연구배경: 수면부족은 당 대사조절 등 체내 생리적 시스템에 영향을 주면서 비만의 유병률을 높일 것으로 생각되는데, 국내외적으로 수면시간과 비만과의 연관성을 다룬 연구는 많이 있으나 체지방량의 분포 등 체성분과의 연관성을 다룬 연구는 거의 없는 실정 이다. 이에 본 논문에서는 우리나라 성인의 수면시간과 체성분과의 연관성을 확인하고자 했다. 방법: 제 4기(2008∼2009)와 제 5기(2010) 국민건강영양조사 자료를 분석하였으며 고령, 미측, 갑상샘 질환, 신부전, 임신을 제외한 총 9880명을 대상으로 하였다. 체성분인자로 BMI, 허리둘레, 총체지방률, 몸통체지방률, 제지방률, 몸통제지방률, 근량을 사용하였고, 수면시간에 따른 체성분 분석의 연관관계를 보기 위해 선형 회귀분석 및 로지스틱 회귀분석을 이용하였으며, 나이, 흡연, 운동, 음주 등의 교란변수를 보정하여 다중 로지스틱 회귀분석을 실시하였다. 결과: 남성과 여성 모두 BMI, 허리둘레, 몸통체지방률, 근량에서 수면시간과 유의한 음의 상관관계를 보였으며, 비만 관련 위험도를 알아보기 위하여 BMI≥25 kg/㎡, 허리둘레(남자≥90 cm, 여자≥85 cm), 체지방률과 제지방률, 근량의 상위 25%값의 비율에 대해 다중 로지스틱 회귀분석을 실시하였을 때는, 남성에서만 유의한 교차비를 보였다. 남성에서 수면시간이 1시간 증가할수록 BMI 25이상의 위험은 0.89배, 허리둘레 90 cm이상 위험은 0.90배, 몸통 체지방률과 근량도 각각 0.93배, 0.89배 감소하였다. 결론: 우리나라 성인의 수면시간은 체성분인자 중 BMI, 허리둘레, 몸통 체지방률, 몸통 제지방률, 근량과 유의한 연관성이 있었으며, 남성에서는 수면시간이 부족할수록 BMI 25 kg/㎡ 이상, 허리둘레 90 cm이상 될 위험이 증가하고, 몸통체지방률이 증가할 위험도 높은 것으로 나타났다. 이러한 결과는 수면부족이 몸통에 체지방량의 분포를 증가시켜 중심비만을 야기시키는 원인이 될 수 있음을 뒷받침하며, 적절한 수면관리를 통해 이를 예방할 수 있을 것으로 사료되므로 이를 지키기 위한 노력이 필요하겠다. Background: Despite the large number of epidemiological studies linking obesity and short sleep duration, there is paucity of data carefully examining the relationship between body composition and sleep duration. So, through national undertaking Korea National Health and Nutrition Examination Surveys (KNHANES), we examined the relationship between sleep duration and BMI, waist circumference, and percent body fat in Korean adults. Methods: From the data of KNHANES in the year of 2008∼2010, over 19 years old 4337 men and 5543 women, relationship between sleep duration and indices of body composition was examined. Anthropometric and dual-energy X-ray absorptiometry (DXA) measures of body composition were used. Sleep duration was measured using information obtained from self-reported questionnaires. Results: The study results revealed a negative association between sleep duration and most of body composition variables - body mass index, waist circumference, truncal fat percentage, muscle mass - and positive association with truncal lean mass percentage. In men, increasing sleep duration 1 hour, prevalence of obesity (BMI≥25 kg/㎡) is decreasing (OR=0.89, CI:0.837-0.939), risk of waist circumference over 90 cm is decreasing (OR=0.90, CI:0.851-0.966), truncal fat percentage (OR=0.93, CI:0.869-0.992) and muscle mass (OR=0.89, CI: 0.835-0.949) are also decreasing. Conclusion: Our results are consistent with previous findings that sleep duration is associated with obesity. However, the relationship between sleep duration and body composition may be stronger in men than in women. Short sleep duration was associated with increased truncal fat. And it supports that short sleep duration may increase prevalence of central obesity in Korean men.
소셜미디어 시대의 설화 활용 문학교육방안: 노원구 지역설화를 중심으로
김은혜(Kim, Eun Hye),정소연(Chung, So Yeon) 학습자중심교과교육학회 2019 학습자중심교과교육연구 Vol.19 No.13
본 연구는 2000년과 2005년의 『인구주택총조사』를 토대로 한 인구이동 분석을 바탕으로 글로벌리즘에서 글로컬리즘으로 변화하고 있는 사회적 흐름을 해석하였고, 멀티미디어에서 소셜미디어로 변화한 현대사회의 문학교육방안을 모색하였다. 농촌 에서 도시로 인구가 밀집되던 산업화 시기와 달리 현대사회는 오히려 수도권에서 비수도권으로 인구가 분산되는 인구이동 경향을 보인다. 또한 소셜미디어는 청소년들에게 친숙한 소통방식으로서 일상생활 문화의 한 부분으로 자리매김하고 있는데, 지 역설화는 ‘상호소통, 공통의 관심사 촉발, 커뮤니티 형성’이라는 소셜미디어의 특성을 가장 긴밀하게 공유하는 문학의 하위 갈래로서 현대적인 방식의 교수-학습과 문학생활화를 가능하게 만든다. 따라서 본 논의는 구비문학, 특히 지역설화를 활용한 문학교육을 통하여 청소년 학습자에게 사회적·문화적 정체성을 부여하고, 다른 문화를 접촉·수용하는 과정에서 확고한 정체성을 바탕으로 사회 통합을 주체적으로 주도해나 갈 수 있는 능력을 함양시키기 위한 방법을 모색하고 있다. 지역설화를 활용한 문학교육은 청소년의 정체성, 관용정신을 함양시키는 전인적 차원의 교육적 효용을 높이며, 소셜미디어 시대를 살아가는 청소년 학습자에게 익숙하고 친밀한 문학공부 방법을 제시한다. Based on the population movement analysis based on the “Population Housing Survey” in 2000 and 2005, this study analyzed the social trends that are changing from globalism to glocalism, and explored the methods of literature education in the modern society that have changed from multimedia to social media. Unlike the era of industrialization, modern society tends to spread its population from the Seoul metropolitan area to the non-capital areas. It is very important for learners to consolidate their identity in this social trend. In the process of contacting and embracing other cultures, they will be able to lead the integration of society by themselves when their firm identity is based on. Especially regional folktale helps youth learners to express their own individuality by giving them social and cultural identities, a period of forming their identity. Social media has also established itself as a part of everyday culture as a communication style that is familiar to teenagers, making it possible for modern methods of teaching-learning and regional folktale shares the characteristics of social media: mutual communication, triggering common interests, and forming a community. Using local folktale, the education system enhances the educational utility of the whole level that fosters the identity and tolerance of young people, and presents a familiar and intimate way of studying literature for young learners living in the age of social media. As part of that method, we propose the creation and sharing of localized content, the creation and sharing of UCCs linking villages. We hope this discussion will be a development discussion that will provide new ideas for learner-oriented education.

목적 본 연구의 목적은 한국과 중국의 체육관련대학 입시제도를 비교하여, 이를 통해 한국 체대입시 제도 발전에 기여할 수 있는 아이디어를 제안하는 것이다. 방법 비교 연구는 대상 간의 유사성, 상이성 그리고 연계성을 포괄하는 연구방법이며, 목적은 공통점과 차이점을 찾는 것이다. 본 연구목적을 달성하기 위해 Bereday(1964)의 4단계 절차인 기술(description) 해석(interpretation) 병치(juxtaposition) 비교(comparison)를 활용하였다. 결과 그 결과는 다음과 같다. 첫째, 입시전형 요소는 비슷하나, 입학시기와 관리기관에 차이가 존재하였다. 둘째, 수능과 실기가 주된 입시전형 요소이나, 두 요소의 반영비중에서 서로 다르게 나타났다. 셋째, 실기유형은 기초체력이 공통점이고 운동기능의 세부 내용 영역이 차이점이다. 넷째, 실기 종목에서 종목은 비슷하나 종목 수에 편차가 존재하였다. 결론 양국의 체육관련대학 입시 비교 연구를 통해, 국가수준 체대 입시 지침서 마련, 지역 중심 연합실기시험, 그리고 필수종목과 선택종목 실기 제도 등을 제안하였다. 위의 3가지 요소를 한국의 현 체대입시 제도에 도입한다면 공정성 확보는 물론 공교육 정상화를 이룰 수 있을 것으로 사료된다. Objectives The purpose of this study is to compare the entrance examination systems for physical education-related universities in Korea and China. Through this, it is to propose ideas that can contribute to the development of the Korean Physical Education College Entrance System(PECES). Methods Comparative study is a method that encompasses similarity, difference, and connection between subjects, and the purpose is to find commonalities and differences. To achieve the purpose of this study, the four-step procedure of Berday (1964), intervention, juxtaposition comparison, was used. Results The results are as follows. First, the element of entrance examination is similar, but there was a difference between the time of admission and the management institution. Second, the College Scholastic Ability Test (CSAT) and practical test were the main factors for the entrance exam, but they were different among the reflection ratios of the two factors. Third, the common denominator of skill types is the basic physical strength, while the difference lies in the detailed area of motor skills. Fourth, The actual skill projects are similar but the number of projects is different. Conclusions Through a comparative study on the entrance examination of physical education-related universities between the two countries, Korea s physical education entrance examination needed to improve guidelines for national-level physical education entrance examinations, regional-centered joint practical tests, and the required and optional practical skill system. If the above three factors are introduced into the current Physical Education College Entrance System(PECES), it is believed that public education can be normalized as well as fairness.
말하기 평가에 구현된 한국어 초급 학습자의 의사소통 전략 양상
김은혜 ( Eun Hye Kim ) 국어교육학회 2011 國語敎育學硏究 Vol.40 No.-
본고는 한국어 초급 학습자의 말하기 평가에서 의사소통 전략이 구체적으로 어떤 양상을 보이는가를 논의하기 위해 의사소통 전략이 무엇이며 의사소통 전략은 의사소통 능력과 어떤 관계를 맺고 있으며 그 유형은 무엇인지에 대해 살펴보았다. 의사소통 과정에 관여하는 여러 요인을 의사소통 모형으로 만들어 보고 화자의 전달 능력과 청자의 이해 능력에 초점을 두어 의사소통 전략의 평가 요소를 추출하였다. 의사소통 전략이 실제 평가에 구현되려면 평가 목적, 대상, 평가 내용에 따라 선별될 필요가 있음에 착안하여 실제 평가를 인터뷰, 대화, 발표라는 각기 다른 말하기 표현 양식으로 구상하였고 인터뷰와 대화, 발표의 각기 다른 양식에서 사용하는 전략에 차이가 있음을 보였다. The purpose of this study is to investigate the aspects of communication strategies in speaking evaluation for beginner level of Korean learners. For this purpose, the definition of communication strategies, the relations between communicative competence and communication strategies, and types of communication strategies were discussed. A communication model and the evaluation criteria of communication strategies were extracted through this process, focusing on speaker`s productive abilities and listener`s receptive abilities. This study included various speaking evaluation tasks such as interviews, dialogues, and presentations because communication strategies should be served differently according to the purpose, subjects, and contents of evaluation. The research showed learners practised different communication strategies according to the context.

김은혜 ( Eun Hye Kim ),이선희 ( Sun Hee Rhee ),이운경 ( Woon Kyung Lee ),김민주 ( Minjoo Kim ),도현심 ( Hyun-sim Doh ) 한국가족복지학회 2017 한국가족복지학 Vol.22 No.1
The purpose of this study was to examine first-time pregnant couples` adaptation processes to parenthood by using the grounded theory approach. The participants were six pregnant couples who were experiencing pregnancy for the first time in their lives. Data were collected through individual in-depth interviews, and then analyzed through the processes of open coding, axial coding, and selective coding based on the grounded theory method. As a result of open coding, thirty concepts, eighteen subcategories, and seven categories were discovered. Following the paradigm analysis of the axial coding, causal conditions, contextual conditions, phenomenon, intervention conditions, and action/interaction strategies that lead to the consequence of “adjustment to parenthood” were analyzed. “Overcoming conflicts during first-time pregnancy and positive adjustment to parenthood” was suggested as the core category after selective coding was carried out. The two types of the adaptation processes were the “gradual adjustment type” and the “active change type.” The results of this study can be used as a basis for developing parent education and family relationship programs for first-time pregnant couples as well as for improving understanding of them.
