This experiment was carried out to evaluate the effects of feeding green tea powder on laying performance and egg quality in hens. A total 180 'Tetran Brown' laying hens aged 40 weeks were assigned to 6 treatments in a completely randomized design. Each treatment consisted of five replicates accommodating six layers per replication. The experimental diets were a negative control containing no green tea, a positive control diet containing antibiotics (0.05% chlortetracycline) and diets containing 0.5%, 1.0%, 1.5% and 2.0% green tea powder. Egg production rate of layers fed the diets containing green tea powder did not differ significantly from that of the negative and positive controls (p>0.05). Egg weight was decreased significantly in the group fed the diet containing 0.5% green tea powder (p<0.05). Feed intake of layers was significantly higher for the diet containing 1.5% green tea powder compared to that of negative and positive control diets (p<0.05). The eggshell thickness reduced significantly in the layer group fed the diets containing green tea powder regardless of dietary levels (p<0.05). Green tea powder tended to reduce egg yolk cholesterol in this experiment. Particularly, dietary 2% level of green tea powder significantly suppressed the cholesterol contents of the egg yolk (p<0.05). Thiobarbituric acid value (TBA) of egg yolk was significantly reduced by green tea diets (p<0.05). The yellowness of egg yolk was increased in the layers fed the 2.0% green tea diet compared with that of control diet (p<0.005). The Linoleic and $\alpha$-linolenic acids tended to increase in the group fed diets containing 1.5% green tea powder even though there were no significant differences among treatments (p>0.05). The oleic and docosahexaenoic acid contents of the egg yolk were similar among treatments (p>0.05). Based on the results of the experiment, it is concluded that green tea powder inclusion in the diet for layers at 2.0% level can reduce the cholesterol content and TBA value of the egg yolk, implying its potential effect on egg quality parameters.

Approximate 2D image generation from laser 3D point clouds for indoor modeling

Uuganbayar Gankhuyag,한지형 제어로봇시스템학회 2020 제어로봇시스템학회 국내학술대회 논문집 Vol.2020 No.7

The indoor modeling from unstructured 3D point clouds has been a challenging task and ongoing research. It supports various fields such as building information model (BIM), navigation inside of buildings, and 2D and 3D floorplan generation. The 2D methods of indoor modelling highly depends on 2D image which has to contain clear wall boundaries as well as high-quality pixels. It becomes more challenging on noisy 3D point cloud data. In this paper, we propose fully automate method to generate approximate 2D image for more accurate indoor modelling. The proposed method consists of three main parts. The first part is to simplify input data that denoise and remove some outliers from unstructured 3D point clouds without changing innate structure or orientation information. The second part is to up sample points for missing points in extracted plane and nearby edges. The last part is to generate 2D image. Our method generates high quality image in low computational cost. We experimented the proposed method on 3D point clouds of residential and house building.

Uuganbayar, D.,Shin, I.S.,Yang, C.J. Asian Australasian Association of Animal Productio 2006 Animal Bioscience Vol.19 No.8

This experiment was carried out to investigate the effects of Korean, Japanese and Chinese green tea on laying performance and egg quality in hens. A total of 168 "Tetran Brown" hens aged 40 weeks were assigned to 7 treatments in a completely randomized design. Each treatment had 4 replicates accommodating 6 layers per replication. The seven dietary treatments were: 1) control diet with no green tea added, 2) diet containing 1.0% Korean green tea (1.0% KGT), 3) diet containing 2.0% Korean green tea (2.0% KGT), 4) diet containing 1.0% Japanese green tea (1.0% JGT), 5) diet containing 2.0% Japanese green tea (2.0% JGT), 6) diet containing 1.0% Chinese green tea (1.0% CGT), and 7) diet containing 2.0% Chinese green tea (2.0% CGT). Egg production rate of the layers fed diets containing 1.0 or 2.0% green tea powders were significantly increased compared to that of the control (p<0.05). The egg weight of layers was significantly reduced in layers fed 1.0% CGT (p<0.05). The feed intake was significantly decreased in KGT and CGT groups at 2.0% inclusion levels (p<0.05). The egg shell thickness and shape index of JGT treatment was significantly lower than that of the control (p<0.05). There were no significant differences in albumen index, yolk index and Haugh unit of eggs for layers fed diets containing green tea powders regardless of origin (p>0.05). Green tea feeding to layers tended to reduce the overall cholesterol content of egg yolk. Particularly, 1.0 or 2.0% CGT significantly depressed the total cholesterol content of egg yolk (p<0.05). In conclusion, incorporation of 1.0 or 2.0% Korean, Japanese and Chinese green tea into layer diets regardless of origin had favorable effects on laying performance and egg quality profiles. Among the three green tea sources, the Chinese green tea powder had the highest reducing effect on cholesterol content in egg yolk.

The sheep can be reproduced by natural mating as well as applied reproductive biotechnology, embryo transfer (ET). However, this method in sheep is influenced by several factors such as season, photoperiod, latitude, temperature, nutrition, and breed. In addition, there is still less research on assisted reproductive technologies in small ruminants, compared to other livestock species such as cattle and pigs. Because there has been a need for an optimization and a continuous improvement of ET techniques in small ruminants. the main objective of this study was to evaluate the conception rate obtained after ET in Mongolian sheep (Dorper breed). After embryo recover, code 1 and 2 embryos (morula or blastocyst stage) for ET in the present study were 63% (63/100) and 24% (24/100), respectively. Then Each single embryo was transferred to a synchronized recipient who prepared by estrous synchronization protocol with fluorogestone acetate-cloprostenol sodium. The results demonstrated that an average conception rate and lambing rate was 35.6% (31/87) and 33.3% (29/87), respectively. Further study is still necessary, but these results indicated that single embryo of Mongolian sheep with the present protocol was enough to conducting ET when the genetically superior sheep were necessary to be expanded.

이 연구는 후견주의(Clientalism) 개념의 적용을 통해 1990년대 이후 체제이행기의 몽고 국내 정치 동향을 분석하고 있다. 후견주의는 근대화 사회의 새로운 이미지와 함께 살아남고 적응하여 등장하였다. 정부의 역할이 국가 경제 속에서 급격히 커짐에 따라 여당은 후견주의적 정치 경쟁 속에서 더 많은 이점을 지녔다. 정치학자들 가운데에서 이와 같은 현상은 후견주의가 더욱 더 인기를 얻음으로 인해 연립정부의 인기 역시 상승한다는 새로운 가설을 제기하였으나 후견주의가 진정으로 연립정부의 인기를 결정하는지에 대하여 논의하기보다 후견주의의 부풀려진 인기가 언제 그리고 어떻게 연립정부로 이끄는지에 대한 질문을 던지는 것이 더욱 생산적이라 할 수 있겠다. 이 논문은 2004년과 2008년의 몽골의 국회선거의 사례에 이론적인 기초를 두고 있다. 다음 조사 결과는 후견주의의 인기도의 상승이 연합 정부의 인기를 반드시 견인하는 것은 아니라고 보여준다. 따라서 공공자원 중심적 후견주의의 교류가 정치 경쟁에서 승리자와 패배자를 결정할 수 있다고 볼 수 있다. Clientelism has survived, adapted, and emerged with new image in modernizing world. As government role has greatly increased in national economy, ruling party has had more advantage in clientelist political competition. Among politics scholars, such new condition has raised a hypothesis which argues more popularity of clientelism leads to more popularity of coalition government, but rather than debating whether clientelism really determines the popularity of coalition, it is more fruitful and interesting to question when and how inflated popularity of clientelism leads to coalition government. This article tries to explain this issue theoretically based on the case of 2004 and 2008 Mongolia`s State Great Khural elections(Mongolia`s parliamentary election). The finding of this research suggests that whether higher popularity of clientelism leads to more popularity of coalition government is conditional. It could occur when public resource centered clientelist exchange determines winner and loser in political competition.

포퓰리즘 후보에게 투표하는 유권자와 그렇지 않은 유권자가 발생하는 것에 영향을 미치는 요인은 무엇인가? 몽골의 투표행위가 포퓰리즘 커뮤니케이션의 부상에 미치는 영향에 관한 연구

포퓰리즘 후보에게 투표하는 유권자와 그렇지 않은 유권자가 발생하는것에 영향을 미치는 요인은 무엇인가? 몽골의 투표행위가 포퓰리즘 커뮤니케이션의 부상에 미치는 영향에 관한 연구이다. 포퓰리즘의 수요와 공급 측면을 가늠하려는 다양한 경쟁 이론과 접근법이 등장했다. 그러나 구 공산국가들의 경우, 기존과는 다른 정치적, 경제적 맥락에서 등장했기 때문에 이들의 포퓰리즘 경향을 설명하고 평가하기 위해서는 더 많은 연구가 필요함에 따라 아직까지 많이 다뤄지지 않았던 이 주제에 대한 연구를 진행했다. 이 연구의 목적은 강력한 독재 리더쉽 및 직접민주주의 혹은 자유민주주의가 구 공산국가인 몽골의 포퓰리즘에 대한 유권자들의 태도에 미치는 영향을 조사하는 것으로, 연구를 수행하기 위해 포퓰리즘 태도를 조사하기 위한 질문지 조사를 설계했으며, 수집된 데이터를 분석하기 위해 로지스틱 희귀분석법을 사용하였다. 이 연구를 통해 두 가지 주요 결론에 도달했다. 조사 결과에 따르면 중국의 시진핑(習近平)과 같은 공산주의 국가의 강력한 지도자를 선호하는 유권자 포퓰리즘 정당과 포퓰리즘 지도자를 선택할 가능성이 더 높으며, 대의민주주의 실패로 인해 직접민주주의를 지지하게 된 사람들은 포퓰리즘 후보를 지지하고 투표할 가능성이 더 높은 것으로 나타났다. Numerous competing theories and approaches have been developed to measure demand and supply sides of populism. However, more studies should be conducted on assessing and interpreting populist attitudes in post-communist countries that have emerged in completely different political and economic settings. This study addresses this gap. We attempted to explore what effects preferences for strong autocratic leadership, direct democracy, and liberal democracy have on populist attitudes in the post-communist Mongolia. To achieve this objective, we developed and conducted survey on populist attitude. We run logistic regression to analyze and interpret data we collected from the survey. This study finds two interesting findings. Those findings suggest that voters who have high preference for strong leaders that can be observed in communist countries like Xi Jinping in China are more likely to vote for populist parties or leaders. Moreover, people who highly support direct democracy in association with failed representative democracy are more likely to vote for populist candidates.

본 연구는 산란계에서 남은 음식물과 녹차 부산물이 산란계의 산란성적과 계란품질에 미치는 영향을 연구하였다. 공시동물은 50주령 Tetran Brown종 산란계 210수를 7처리 5반복 (반복당 6수)으로 임의 배치하였다. 시험설계는 대조구와 옥수수 곡류와 대두박을 대용한 건조된 남은음식물 10, 20, 30 및 40% 첨가구 (10% DLF, 20% DLF, 30% DLF 및 40% DLF)와 1.0%의 녹차 부산물 첨가구 (1.0% GTB)와 30% DLF와 1.0% GTB를 첨가한 혼합 첨가구를 두어 사양실험을 8주 동안 실시하였다. 산란율은 대조구에 비하여 10, 20 및 40% DLF 처리구에서 유의적으로 증가하였다 (P<0.05). 난중은 대조구에 비하여 10% DLF 처리구에서 유의적으로 감소하였다 (P<0.05). 사료 섭취량은 대조구보다 20% DLF 처리구와 30% DLF와 1.0% GTB의 혼합 첨가구에서 높게 나타났다 (P<0.05). 사료 요구율은 대조구에 비하여 10% DLF 처리구와 1.0% GTB 처리구에서 유의적으로 감소하였다 (P<0.05). 난황 콜레스테롤은 DLF 처리구와 대조구 사이에서 변화가 없었다 (P>0.05). 난황의 리놀렌산은 DLF 처리구와 1.0% GTB 첨가한 처리구에서 유의적으로 증가하였다. This study was designed to determinate the effects of dried leftover food and green tea by-product on laying hens performance and egg quality in hens. A total of 210 “Tetran Brown” layers 50-weeks of age were assigned to 7 treatments in a completely randomized design. Each treatment had five replicates per treatment with six layers per replication. Seven dietary treatments were a control diet (formula diet) and dried leftover food (DLF) mixed in 10, 20, 30 and 40% to the control diet substituting the corn grain and soybean meal, control diet containing 1.0% GTB without DLF supplementation and control diet containing 30% DLF plus 1.0% GTB supplementation. The trial period was for 8 weeks. The egg production rate of layers was significantly increased in 10, 20 and 40% DLF treatments compared to that of the control treatment (P<0.05). The egg weight was significantly decreased in 10% DLF treatment compared to that of the control (P<0.05). The feed intake of layers was higher in 20% DLF and 30% DLF plus 1.0% GTB treatment than that of the control (P<0.05). The feed conversion ratio significantly decreased in 10% DLF and control plus 1.0% GTB treatments compared to that of the control (P<0.05). The egg yolk cholesterol not varied among the DLF and control treatments (P>0.05). However, the linolenic acid content of egg yolk was significantly increased in DLF and control treatments both containing 1.0% GTB supplementation.

<P>The ATP-binding cassette subfamily C member 4 gene encodes a transmembrane protein involved in the export of proinflammatory molecules, including leukotriene, prostaglandin, and sphingosine-1-phosphate across the plasma membrane. Those metabolites play important roles in asthma. We investigated the potential associations between <I>ABCC4</I> gene polymorphisms and asthma phenotype. In total, 270 asthma patients and 120 normal healthy controls were enrolled for a genetic association study. Two polymorphisms (−1508A>G and −642C>G) in the <I>ABCC4</I> promoter were genotyped. The functional variability of the promoter polymorphisms was analyzed by luciferase reporter assay. Inflammatory cytokine levels were measured by enzyme-linked immunosorbent assay. Serum and urinary eicosanoid metabolites, sphingosine-1-phosphate, were evaluated by quadrupole time-of-flight mass spectrometry. Asthma patients carrying the G allele at −1508A>G had significantly higher serum levels of periostin, myeloperoxidase, and urinary levels of 15-hydroxyeicosatetraenoic acid and sphingosine-1-phosphate (<I>P</I> = 0.016, <I>P</I> = 0.027, <I>P</I> = 0.032, and <I>P</I> = 0.010, resp.) compared with noncarrier asthma patients. Luciferase activity was significantly enhanced in human epithelial A549 cells harboring a construct containing the −1508G allele (<I>P</I> < 0.01 for each) compared with a construct containing the −1508A allele. A functional polymorphism in the <I>ABCC4</I> promoter, −1508A>G, may increase extracellular 15-hydroxyeicosatetraenoic acid, sphingosine-1-phosphate, and periostin levels, contributing to airway inflammation in asthmatics.</P>
