After 2010, Kim Jong-un regime have a quite different action from the previous one in the stronger economic sanctions, The Kim Jong-un regime seek change and transformation in all areas of society. It is also true that policy changes and social systems, sometimes called innovation, have been transformed into crisis response systems whenever the North Korean regime faces a crisis. However, the separation of the Kim Jong-un regime from the Kim il-sung and Kim Jong-il is actively making efforts to become a proud and normal state in the world, free from isolation and closure, and also reflect this in their policies. In the midst of these changes, the Kim Jong-un regime is pushing for changes in cultural heritage policies as a means of globalization strategy. In particular, it is noted that the period when the immaterial cultural heritage policy is incorporated into the legal system and the period when the Kim Jong-un regime emerges as real power, are intertwined. The driving force of change can be found in the “socialist civilization”, one of the representative policies of the Kim Jong-un regime. The Kim Jong-un regime set the national goal of building a socialist civilized country, and induces them to gather in all areas of society, including economy, education, health, sports, social culture, and arts, with the goal of building a socialist civilized country. Among these, non-material cultural heritage promotes internal convergence by emphasizing the excellence of the country As a normal country, it promotes the image of the country both internally and externally, Under the economic benefits through tourism,service trade, the Kim Jong-un regime has revised at a three times, been raising its status among the major policies of the Kim Jong-un regime. As North Korea’s immaterial cultural heritage, folk dance is uniquely linked among various immaterial cultural heritages specified by the law such as national games, national customs, holiday events, various ceremonies, and stage arts. It is also linked to other genres, such as folk songs, traditional music, and costumes. The characteristics acquired through policy in North Korea’s political society reflect the wide range of traditional cultures and historical layers and status of national culture, as well as the politics and society of the North Korean regime of the time.

붉은곰팡이병은 주로 Fusarium graminearum에 의해 발생하며 전세계적으로 주요 곡물에 치명적인 피해를 주는 식물병이다. 관행농가에서는 일반적으로 붉은곰팡이병 방제에 합성살균제를 사용하고 있지만 장기적인 합성살균제의 사용으로 인하여 환경 오염 문제와 인간의 건강을 위협하는 문제가 야기되었다. 때문에 천연물살균제를 포함한 친환경 생물농약 개발에 대한 관심이 고조되고 있는 실정이다. 본 연구에서는 100종의 식물추출물을 이용하여 F. graminearum에 항진균 활성을 갖는 식물 추출물을 탐색하였다. 그 결과 자단 심재부인 자단향의 조추출물이 가장 강한 항진균활성을 보였으며, GC-MS 분석을 통하여 자단향으로부터 ${\alpha}$-cedrol과 widdrol로 동정된 두개의 항진균 활성물질을 분리하였다. ${\alpha}$-Cedrol과 widdrol의 F. graminearum 포자발아 억제활성 최소저해농도는 각각 31.25 mg/l과 62.5 mg/l였으며, 이 두 물질은 F. graminearum 이외에도 다양한 식물병원균의 균사 생육을 저해하였다. 더욱이 자단향 추출물을 분말 수화제로 제형화하여 처리한 결과, 밀 붉은 곰팡이병에 대한 방제효과는 유효성분 농도가 높을수록 효과적인 방제가를 보였으며, 250배 희석처리 시 2,000배의 상용농도로 희석한 합성살균제의 방제가(92.6%)와 통계적으로 유사한 87.2%의 병방제가를 보였다. 본 연구결과는 붉은곰팡이병방제를 위한 효과적인 생물살균제로 자단향 추출물이 활용 가능하다는 것을 제시하고 있다. Fusarium head bight (FHB) is a devastating disease on major cereal crops worldwide which causes primarily by Fusarium graminearum. Synthetic fungicides are generally used in conventional agriculture to control FHB. Their prolonged usage has led to environmental issues and human health problems. This has prompted interest in developing environmentally friendly biofungicides, including botanical fungicides. In this study, a total 100 plant extracts were tested for antifungal activity against F. graminearum. The crude extract of Pterocarpus santalinus heartwood showed the strongest antifungal activity and contained two antifungal metabolites which were identified as ${\alpha}$-cedrol and widdrol by GC-MS analysis. ${\alpha}$-Cedrol and widdrol isolated from P. santalinus heartwood extract had 31.25 mg/l and 125 mg/l of minimal inhibitory concentration against the spore germination of F. graminearum, and also showed broad spectrum antifungal activities against various plant pathogens. In addition, the wettable powder type formulation of heartwood extract of P. santalinus decreased FHB incidence in dose-dependent manner and suppressed the development of FHB with control values of 87.2% at 250-fold dilution, similar to that of chemical fungicide (92.6% at 2,000-fold dilution). This study suggests that the heartwood extract of P. santalinus could be used as an effective biofungicide for the control of FHB.

In this paper, a study was conducted on an induction type heating device to remove snow and ice that may cause obstacles and malfunctions of the railway switch. In the induction heating device, an ohmic loss is the heat source. Ohmic loss and heat transfer change greatly depending on the shape and material of the heating device and condition of the atmosphere. Since the loss must be accurately calculated to conduct the thermal analysis properly, it is necessary to analyze the electromagnetic and thermal characteristics and to interlock of electromagnetic and thermal analysis. Therefore, the electromagnetic and thermal analysis was conducted using finite element method (FEM). By the performance test of the prototype, verification of the simulation was conducted.

본 논문에서는 신경망을 이용하여 텍스타일 영상으로부터 인간의 감성을 인식할 수 있는 시스템을 제안한다. 자동감성인식 시스템의 구현을 위해 220장의 텍스타일 영상을 수집한 후, 일반인 20명을 대상으로 설문조사를 실시하였다. 이를 통해 텍스타일 영상에서의 패턴과 감성간의 상관관계, 즉 특정 패턴이 사람의 감성에 영향을 준다는 것을 발견하였다. 따라서 본 연구에서는 텍스타일 영상에 포함된 패턴의 인식을 위해 신경망을 이용하였으며, 이때 패턴 정보의 추출을 위해 두 가지 특징 추출 방법을 사용한다. 첫 번째는 auto-regressive method를 이용한 raw-pixel data extraction scheme(RDES)을 사용하는 것이고, 두 번째는 wavelet transformed data extraction scheme(WTDES)을 사용하는 것이다. 제안된 시스템의 유용성을 증명하기 위해서 실제 100장의 텍스타일 영상을 감성을 인식하는데 사용했다. 그 결과 RDES와 WTDES를 사용했을 때 각각 71%와 90%의 인식률로, WTDES를 사용했을 때가 RDES를 사용했을 때보다 더 좋은 성능을 보였다. 데이타 추출방법에 따라 다소 차이가 있었지만 전체적으로 약 81%의 정확도를 보였다. 이러한 실험 결과는 제안된 방법이 감성인식 기반으로 텍스타일 데이타를 검색 할 수 있는 시스템 및 다양한 산업 분야에 응용 가능함을 보여주었다. This paper proposes a neural network based approach for automatic human emotion recognition in textile images. To investigate the correlation between the emotion and the pattern, the survey is conducted on 20 peoples, which shows that a emotion is deeply affected by a pattern. Accordingly, a neural network based classifier is used for recognizing the pattern included in textiles. In our system, two schemes are used for describing the pattern; raw-pixel data extraction scheme using auto-regressive method (RDES) and wavelet transformed data extraction scheme (WTDES). To assess the validity of the proposed method, it was applied to recognize the human emotions in 100 textiles, and the results shows that using WTDES guarantees better performance than using RDES. The former produced the accuracy of 71%, while the latter produced the accuracy of 90%. Although there are some differences according to the data extraction scheme, the proposed method shows the accuracy of 80% on average. This result confirmed that our system has the potential to be applied for various application such as textile industry and e-business.

Purpose:The ob gene, specifically expressed in adipocyte, encodes leptin, a hormone that induces satiety and increases energy expenditure. In this study, effects of saturated fatty acid and polyunsaturated fatty acid on ob gene expression were investigated by quantitative competitive RT-PCR in a mouse cell line (3T3-L1) which can be induced to differentiate into adipocytes. In addition to ob gene, expression of the fatty acid synthase gene as a marker of lipogenesis was measured simultaneously. Materials and Methods:The 3T3-L1 fibroblast cell were cultured in the Dulbecco`s modified Eagle medium with 10% fetal bovine serum. The differentiation of 3T3-L1 fibroblast to adipocyte was induced by the treatment of 250 nM dexamethasone and 0.5mM 1-methyl-3 -isobutylxanthine. At 10∼14 days after induction, 3T3-L1 cells were fully differentiated and had had lipid droplets in the cytoplasm. At that time, 3T3-L1 adipocytes were cultured for 12 hours in the fatty acids contained medium and were harvested for RNA extraction. Palmitate as a saturated fatty acid and docosahexaenoic acid (DHA) as a polyunsaturated fatty acid were used in this experiment and treated concentration was 600 μMol. Results:After conversion to adipocytes, glycerol-3 phosphate dehydrogenase activity was increased and leptin mRNA was expressed, Ob gene expressions of differentiated adipocytes were suppressed by palmitate treatment, however, there was no significant change in DHA treated adipocyte. Fatty acid synthase gene expressions, on the other hand, were suppressed by DHA treatment and not changed by palmitate treatment. Conclusion:These results suggested that polyunsaturated fatty acid inhibited lipogenic process and saturated fatty acid inhibited lipolytic process at cultured adipose cell level.

낙인이 자살생각에 대한 도움요청의도에 미치는 영향

김지인(Ji-In Kim),권호인(Ho-In Kwon) 한국콘텐츠학회 2017 한국콘텐츠학회논문지 Vol.17 No.11

자살 위험성이 있는 사람이 주변지지 체계에 도움요청을 하는 행위는 자살예방에 있어서 매우 중요한 요소이다. 본 연구에서는 한국 군 병사를 대상으로 자살생각에 대한 도움요청의도에 영향을 미치는 요인과 그 기제를 파악하는 목적으로 수행되었다. 이를 위하여 총 471명의 한국 군 병사가 이 연구에 참여하였으며, 이들을 대상으로 사회적 낙인과 자기 낙인이 자살생각과 도움요청의도의 관계를 매개하는지를 살펴보았다. 연구 결과, 사회적 낙인과 자기 낙인은 자살생각과 도움요청의도를 부분 매개 하는 것으로 나타나, 자살생각은 낙인을 통해 간접적으로 도움요청의도에 영향을 미칠 뿐 아니라 직접적으로도 영향을 주는 것으로 나타났다. 또한 사회적 낙인은 자기 낙인을 강화시킬 뿐 아니라 직접적으로 도움요청 의도를 약화시키는 것으로 나타났다. 이러한 결과는 한국 군 병사의 자살에 대한 도움요청 행동을 증가시키기 위해서는 사회적 낙인과 자기 낙인 모두를 감소시키는 자살예방개입이 필요하다는 것을 시사한다. The purpose of this study is to find out factors affecting intentions to seek help for suicidal ideation in Korean Army and to provide a basis for approaches to facilitate formal or informal help seeking for suicidal ideation. A total of 471 Korean soldiers participated in the current study. First, the question of whether suicidal ideation have a significant influence on general help seeking, and whether public stigma and self stigma mediate the relationship between suicidal ideation and general help seeking were examined. According to the results, public stigma and self stigma partially mediated the relationship between suicidal ideation and general help seeking, indicating that suicidal ideation not only has an indirect effect on general help seeking through public stigma and self stigma, but also has a direct influence on general help seeking.
