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.

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.

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.

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.

Objectives: The purpose of this study is to develop the Respected Parents & Respected Children program for first-time expectant parents, and to investigate the effectiveness of the program. Methods: The program aims to help participants adjust to the transition to parenthood. The weekly program, composed of three phases - introduction, development, and closing - consists of a total of six two-hour sessions. In order to verify the effectiveness of the program, a pretest-posttest control group design was used. The participants in this study were 78 first-time expectant parents in Seoul, Gyeonggi province, and Daegu Metropolitan City. Sixteen couples were assigned to an intervention group and 23 to a control group. The data were analyzed by independent two-sample t -tests and repeated measures ANOVA using SPSS 21.0. Results: The couples in the intervention group showed positive changes in parenting beliefs, as well as increases in life satisfaction and marital intimacy as compared to those in the control group. Regarding the changing patterns, life satisfaction and marital intimacy increased in the intervention group, but decreased in the control group. In addition, child-centered views in the intervention group were little changed, while those in the control group were weakened. Parenting beliefs became more personality centric in the intervention group and more intellect centric in the control group. Stress during pregnancy was decreased in both groups. Conclusions: This study confirmed the effectiveness of the program and emphasized the need for preventive intervention for first-time expectant parents.

TV 애니메이션의 서사전략 : SBS <용의 전설 레전더>를 중심으로

김은혜(Kim Eun-Hye) 국어문학회 2006 국어문학 Vol.41 No.-

This thesis aims to examine the narration strategy of <Legender>, a TV animation produced in Japan and now showing in Korea. In case of Japanese animation occupying over 70% of world market, possession of fictional narrative in cultural industry strategy of one-source multi-use encroaches upon actual lives such as costumes, character toys and games simultaneously. Frequent contact of goods related to narrative in daily life makes Korean children and adolescents fascinated to TV narration more effectively and strongly."Tarispod"in <A Legend of Dragon, Legender> is the medium that connects the past with present and the world of imagination with that of the reality. In the mean time, real items of"Tarispod"that can be directly purchased and touched is used as a narration strategy of absorbing into narrative, making users confused of reality and fiction. In addition, by shoring the sex discriminative narration strategy that emphasizes sexuality of female characters, motherhood myth, dichotomous sex role of private area and public areas as well as human superiority and capitalism cheerfully and brightly, it leads young viewers to follow in the fixed idea of patriarchic ideology unconsciously. That is, <A Legend of Dragon, Legender> excludes the dream and reality of girls but disseminate eager for forceful power and pleasure of sexual image, targeting only boys.
