본 논문은 한국에 거주하고 있는 일본결혼이주여성들의 갈등과 문화적응과정을 전환학습적인 접근으로 파악하여 분석하며 삶의 특징을 찾아 논술하였다. 연구방법은 일본결혼이주 여성 8명을 대상으로 반 구조화된 심층면담을 하였고 분석방법은 근거이론의 특징을 가지며 코딩기법의 분석부분을 명확하게 수정한「수정판 M-GTA」(Yasuhito.K. 2003)를 이용하였다. 한국에 거주하고 있는 일본결혼이주여성들은 문화적응과정에 있어서 경제적인 갈등, 남녀(부부) 간의 갈등, 세대 간의 갈등, 문화적인 갈등 등을 가지고 있으며 이러한 갈등을 극복하려고 할 때 어려움을 ‘탕감’으로 수용하여 관점전환을 일으켜 전환학습을 이루어 나가 는 특징을 찾을 수 있었다. 전환학습의 1단계는 ‘어려움과 갈등’을 느끼는 경험이며 ‘어려움을 수용’(2단계) 하게 되면 자기성찰을 통한 비판적인 반성으로 관점전환이 이루어지며 ‘상대에 대한 이해’(3단계)가 생기고 ‘자신에 대한 반성․이해․자각’(4단계)을 하게 되어 어려움을 극복하게 된다. 적극적으로 ‘상대 문화를 배우기’(5단계)도 하고 ‘새로운 사고․가치 관․태도의 변화’(6단계)가 생기기도 하고 갈등의 요인과 사람, 전환학습의 진도에 따라 다양한 문화적응과정을 찾을 수 있었다.

최근의 예멘 난민 사태는 국제난민 이슈가 한국인의 일상으로 다가올 때 타나는 시민사회의 충격파를 보여주었다. 10여 년간 다문화 정책에 투여한 정부의 재정과 시민단체의 인식 개선 노력이 무색할 정도로 제주도 예멘 난민 이슈는 반(反)다문화주의 현상을 심화시켰다. 이 논문은 세계시민성 관점에서의 이주민 성원권 개념을 바탕으로 예멘 난민을 둘러싸고 나타난 다양한 논쟁의 교차점을 분석하였고 다문화교육이 나아가야 할 방향을 비판적으로 고찰하였다. 난민과 이주민의 성원권에 관한 논의 실종, 난민 권리에 대한 이해와 학습의 부재, 그리고 이질성을 가진 타자의 사회 참여에 대한 현재의 다문화교육의 이슈와 문제를 분석하였으며, 궁극적으로 난민 문제를 보편적인 성원권과 인권의 실천이라는 관점에서 담아내기 위한 다문화교육의 재구조화를 주장하였다.

국화과에 속하는 단풍취의 추출물이 가지는 알츠하이머에 대한 효과를 알기 위하여 AChE에 대한 억제효과와 peroxy-nitrite 소거효과를 연구하였다. 단풍취 추출물은 AChE에 대한 억제효과로서 그 IC50가 73.4 μg/ml이었으며 peroxynitrite 소거효과에 관한 IC50는 8.60 μg/mL이었으므로 알츠하이머 질환에 유익할 것으로 판단된다. 단풍취에 가장 많이 함유된 성분인 3,5-dicaffeoylquinic acid 성분의 활성도 이와 유사한 활성을 보였으므로 단풍취 추출물의 효과는 주로 이 화합물의 활성에 따른 것으로 예상된다. Caffeoylquinic acid가 알츠하이머 질환에 효과있다는 보고가 있으므로 이 식물의 잎과 줄기 추출물에서 6종의 지표물질을 이용하여 정량법을 확립한 후 정량하였다. 그 결과 잎에서는 성분 함량이 25.1%를 차지하여 줄기의 함량보다 훨씬 높았다. 특히 잎 추출물 중 3,5-dicaffeoylquinic acid의 함량이 145.6 ㎎/g에 달하여 알츠하이머 질환 치료에 유익할 것으로 예상된다.

Background: Sancho (Zanthoxylum schinifolium Siebold and Zucc) oil is used as a traditional medicinal material to treat severs stomach inflammation and as a diuretic. This study was carried out to investigate the effect of addition of antioxidants and blended oil the storage stability and safety of the biomaterial. Methods and Results: The effects of temperature and light on sancho oil were investigated, and the ability of antioxidants in preventing rancidity of the oil was discovered. Under fluorescent light and in darkness, the acidity of the oil was much lower than that under direct sunlight. The addition of antioxidants decreased the acid value of sancho oil; the antioxidant that showed the best results in this regard was 0.5% propolis. The acid value of canola oil, which had the lowest acid value compared with that of other oils, and blended oil, containing 5% canola oil in sancho oil, decreased by 5.5% and 15%, respectively. About one acid value decrease was observed for every 1% increase in blending with canola oil. As the concentration of canola oil increased, the viscosity and the elightness (L valu) of sancho oil increased slightly, while the blueness (b value) decreased. Conclusions: The results of this study may contribute to ensuring food safety during preservation and the industrialization of the presevation of sancho oil.

The motivation of this paper is to identify the variation of stress filed in multi-strand tendon anchorage system using electromechanical impedance measurement. To achieve the objective, the following approaches are implemented. Firstly, stress variation in multi-strand anchorage system due to strand breakage is analyzed to determine the location of impedance acquisition. Secondly, a piezoelectric-based interface technique is designed to localize the damage strand. Lastly, the conceptual design of the PZT-interface is preliminarily verified by an experimental test. Impedance signatures obtained from PZT-interface are quantified by using RMSD index (root-mean-square-deviation). The result shows that the PZT-interface technique is promisingly to identify damage strands.

In this paper, a soft robotic arm which can prevent impact injury during human-robot interaction is introduced. Two degrees of freedom joint are required to realize free movement of the robotic arm. A robotic joint concept with a single degree of freedom is presented using simple inflatable elements, and then extended to form a robotic joint with two degrees of freedom joint using similar manufacturing methods. The robotic joint with a single degree of freedom has a joint angle of 0° bending angle when both chamber are inflated at equal pressures and maximum bending angles of 28.4° and 27.1° when a single chamber if inflated. The robotic joint with two degrees of freedom also has a bending angle of 0° in both direction when all three chambers are inflated at equal pressures. When either one or two chambers were pressurized, the robotic joint performed bending towards the uninflated chambers.

In addition, transcriptional gene regulation was quantified by the real time PCR for targeting adipogenic genes such as PPARγ, STAT3, CEBPα, ap2 and aP2 as well as hepatogenic genes such as ACC, AMPK, FAS and PPARα. Moreover, protein expression was evaluated by immunoblotting assay. Conclusion : Altogether, the above results were confirmed that BSA-F1 at dose 25 μM exhibited the anti-adipogenesis effect by downregulating the major transcriptional factors PPAR γ/STAT3 in signalling in 3T3-L1 mature adipocytes and upregulated the fatty acid oxidative AMPK signaling in fatty acid induced HepG2 hepatocytes.

Background : Anemarrhena asphodeloides has efficacy such as anti-fungal, anti-cancerous, anti-inflammatory, anti-diabetic, Anti-UV etc. Metal nanoparticles are used for photo imaging, cancer resection and drug delivery etc in medical field. Therefore A. asphodeloides nanoparticles will be expected better efficacy for therapeutic properties in medical field. Methods and Results : The water extract of A. asphodeloides mediated the synthesis of Aa-AgNPs and Aa-AuNPs. Their characterized by several physicochemical techniques such as UV-Vis spectrophotometry, FE-TEM, EDX spectroscopy, SAED pattern, DLS size analysis, XRD analysis, and FTIR analysis. Both Aa-Ag/AuNPs were evaluated for cytotoxicity towards 3T3-L1, A549, HT29 and MCF7. Aa-AgNPs and Aa-Au NPs were found to be spherical, face-centered cubic nanocrystals with hydrodynamic diameter of 190 and 258 ㎚. In vitro cytotoxic analysis revealed that up to 50 ㎍/㎖-1 concentration Aa-Au NPs did not exhibit any toxicity on 3T3-L1, HT29 and MCF7 cell lines, while being specifically cytotoxic to A549 cell line. On the contrary, Aa-Ag NPs displayed a significantly higher toxicity in all cell lines specially MCF7 cell line. ROS generation was not affected by Aa-Au NPs, but Aa-AgNPs has a higher potential to induce oxidative stress in A549 cells than HT29 and MCF7 cells. Aa-Au NPs have the potential for anticancer agent during lung cancer treatment. Aa-AgNPs is also exhibited to inhibit cell migration by induce oxidatie stress. Conclusion : The Aa-Au/AgNPs might have the anticancer potential and might be effective in the lung cancer therapy, however further evaluation is must needed.

The talking head (TH) indicates an utterance face animation generated based on text and voice input. In this paper, we propose the generation method of TH with facial expression and intonation by speech input only. The problem of generating TH from speech can be regarded as a regression problem from the acoustic feature sequence to the facial code sequence which is a low dimensional vector representation that can efficiently encode and decode a face image. This regression was modeled by bidirectional RNN and trained by using SAVEE database of the front utterance face animation database as training data. The proposed method is able to generate TH with facial expression and intonation TH by using acoustic features such as MFCC, dynamic elements of MFCC, energy, and F0. According to the experiments, the configuration of the BLSTM layer of the first and second layers of bidirectional RNN was able to predict the face code best. For the evaluation, a questionnaire survey was conducted for 62 persons who watched TH animations, generated by the proposed method and the previous method. As a result, 77% of the respondents answered that the proposed method generated TH, which matches well with the speech.
