Xue Yuan,Shuai Huang,Huiling Ma,Ning Huang,Niu Ye 한국원예학회 2019 Horticulture, Environment, and Biotechnology Vol.60 No.3

In this study, we screened eight walnut ( Juglans regia L.) cultivars (‘Xifu2’, ‘Shaanhe’, ‘Weina’, ‘Xiangling’, ‘Xiluo3’,‘Xifu1’, ‘Liaoning4’, and ‘Qingxiang’) in order to establish reliable selection criteria for storage-tolerance. Fresh walnutfruit were stored at 0 ± 0.5 °C and 70–80% relative humidity. Browning index, postharvest physio-biochemical characteristics,acid value, and sensory quality were measured. The results showed that ‘Xifu2’, ‘Shaanhe’, and ‘Weina’ developedbrowning early and quickly and storage was terminated for these cultivars at 60 days. ‘Xiluo3’, ‘Xifu1’, ‘Liaoning4’, and‘Qingxiang’ had a slow browning rate and storage was terminated at 72 days. ‘Xiangling’ developed browning at a mediumrate and storage was terminated at 72 days. Correlation analysis suggested that the terminal browning index of each cultivarpositively correlated with lipoxygenase activity at 18 days of storage, polyphenol oxidase activity at 18–30 days, malondialdehydecontent at 18 days, and the respiration rate at 42 days, while it negatively correlated with the total phenolic contentat 18 days and phenylalanine ammonia lyase activity at 12 days. The storage tolerance of each cultivar was evaluatedaccording to the terminal browning index, acid value, and sensory quality. Comprehensive evaluation and cluster analysiswere performed to rank the cold storage tolerance of the eight cultivars as follows: ‘Qingxiang’ and ‘Xifu1’ > ‘Liaoning4’and ‘Xiluo3’ > ‘Xifu2’ and ‘Xiangling’ > ‘Shaanhe’ and ‘Weina’. In conclusion, cultivars used for fresh in-husk walnut fruitwith lower levels of membrane peroxidation and phenol oxidation, and higher level of phenol synthesis around 18 days ofstorage would be suitable candidates for cold storage. ‘Qingxiang’ and ‘Xifu1’ were selected as storage-tolerant cultivars.

Xue-Lin Wang,Peng Liu,Qing Huang,Xue-Feng Xu,Sha Yan 한국물리학회 2010 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.56 No.4

This paper reports the basic results obtained from an investigation of the microstructure of lithium niobate (LiNbO3) crystals fabricated by using the focused ion beam (FIB) sputtering method. The morphology characterization of the microstructure is explained in terms of scanning electron microscopy observations based on the geometrical integrity, surface smoothness, cross-sectional area, aspect ratio, etc. The optimized micro-fabrication conditions and the sample morphology characterization are presented, and the sputtering rate of Ga ions for a 30-keV energy milling of the LiNbO3 crystal is calculated, which is lower than the theoretical one gained from “The Stopping and Range of Ions in Matter” (SRIM) sputtering simulation due to the redeposition effect being enhanced with increasing milling depth

A Hybrid Double Self-lift Switched-Coupled Inductor Quasi-Z-Source Inverter

Huang Dong,Xue Pengfei,Chen Guang,Zhang Chaozhong,Zhao Chang,Huang Yuchen,Ding Xinping,Zhang Min 대한전기학회 2022 Journal of Electrical Engineering & Technology Vol.17 No.4

A hybrid double self-lift switch-coupled-inductor quasi-Z-source inverter (HDSCL-qZSI) is proposed in this paper. The voltage boost capability is higher and the voltage and current stress on components are lower than the existing quasi-Z-source topologies. Owing to the strong current handling ability and step-down coupled-inductor, the magnetic elements are smaller than that of mSSCL-qZSI and SCL-qZSI whose structure are similar to that of HDCSL-qZSI. The operation principles, comparisons of voltage and current stress on components and the size of magnetic elements are analyzed theoretically. Finally, the eff ectiveness of the proposed HDSCL-qZSI was validated by a 1 kW prototype fabricated in the laboratory.

Xue Huang,Jiayi Xu,Feng Gao,Hongyan Zhang,Ling Guo 한국식품과학회 2022 Food Science and Biotechnology Vol.31 No.9

Amygdalin content in apricot kernels is an essential factor in the rapid and nondestructive identification of sweet or bitter apricot kernels through spectroscopy. Now, amygdalin content has been determined by high-performance liquid chromatography and near-infrared spectral database to construct a model so that the sweet or bitter apricot kernels could be identified and classified. Principal component analysis–K-nearest neighbor classification algorithm combined with multivariate scattering correction pretreatment method could distinguish sweet and bitter apricot kernels in the wavelength range of 1650–1740 nm with 98.3% accuracy and apricot kernel species with 96.3% recognition rate in the full wavelength spectrum. Furthermore, prediction of amygdalin content in bitter and sweet apricot kernels by partial least squares model was superior to that by back-propagation neural network model. This study provides a theoretical basis for quality identification of apricot kernel quality, as well as a method for nondestructive and rapid detection of sweet and bitter apricot kernels.

Tao Huang,Ya‑dong Wang,Ming‑ming Xue,Xue Feng,Cai‑Xia Sun,An‑si Wang,Shu‑yu Xie,Meng Zhang,Gui‑Rong Sun,Ming Li 한국유전학회 2018 Genes & Genomics Vol.40 No.7

Reproduction is a complex physiological process that is regulated by multiple genes and pathways. Compared with studies of common livestock, fewer studies of genes related to the fertility of rabbits (Oryctolagus cuniculus) have been reported, and the molecular mechanism of their high productivity is still poorly understood. To identify candidate genes associated with development and prolificacy in rabbits, we analyzed gene expression differences among the ovaries of mature Californian rabbit (LC), and mature (HH) and immature Harbin white rabbit (IH) using digital gene expression technology. We detected 885 and 321 genes that were significantly differentially expressed in comparisons between HH/IH and HH/LC, respectively. The functions of the differentially expressed genes (DEGs) were determined by GO classification and KEGG pathway analysis. The results suggest that most of the DEGs between the mature and immature developmental stages were predominantly associated with DNA replication, cell cycle, and progesterone-mediated oocyte maturation, and most were up-regulated in the IH group compared with the HH group. The DEGs involved in disparate fecundities between HH and LC were associated with reproduction, fructose and mannose metabolism, steroid hormone biosynthesis, and pyruvate metabolism. Our results will contribute to a better understanding of changes in the regulatory network in ovary at different developmental stages and in different fertility of rabbit.

모션 그래픽은 아이디어를 디지털 이미지로 표현해 영상이나 애니메이션 기술을 활용하여 메시지를 전달하는 방식이다. 이러한 모션 그래픽의 전달하는 방식은 어려운 콘텐츠의 내용을 이해하기 쉽도록 전달하는 매체로서 활용하기 용이한 방법이다. 하지만 도자기 관련 박물관에서 도자기의 형태나 제작과정 등의 중요한 정보를 사진과 일러스트레이션, 2D그래픽 등 정적인 이미지로 관람자에게 제공하는 경우가 많다. 따라서 본 연구에서는 도자기 문화재에 대한 정보 인지의 정확성을 높이기 위해 중국 경덕진(景徳鎭) 도자기 박물관의 원대(元代) 모란꽃 문양 매병 청화백자 제작과정을 2가지 버전으로 제공하였다. 첫 번째 버전은 움직임이 없는 키 이미지들로 제작과정을 제공하였으며 두 번째 버전은 모션 그래픽을 활용하여 제작과정을 제공하였다. 설문은 한국인 성인 65명을 대상으로 설문을 진행하였으며. 그 결과, 모션 그래픽을 활용한 중국 도자기 문화재 제작과정 안내 콘텐츠 디자인은 정보전달에 있어 매우 효과적임을 확인할 수 있었다. 동적인 모션 그래픽을 시청하는 관람객은 고정적인 이미지를 보는 관람객보다 전반적으로 높은 정보 인지 수준의 결과를 보였다. 특히 유약 칠하기 단계에서 복잡한 단계의 이해가 필요하였는데 이를 정확하게 이해하는 정보 인지 수준의 차이는 뚜렷한 특징이 있었다. 모션 그래픽을 활용한 중국 도자기 문화재 제작과정 안내 콘텐츠 디자인 개발을 통해 정지되어 있는 이미지보다 모션 그래픽으로 제공된 움직이는 시각 이미지를 통해 많은 지식과 감상을 할 수 있을 것이다. 따라서 다양한 문화재의 콘텐츠와 모션 그래픽을 활용한 연구가 활발히 진행되길 기대한다. Motion graphics are a method of expressing ideas in digital images and delivering messages using video or animation technology. This method of delivering motion graphics is an easy method to use as a medium to deliver difficult content in an easy-to-understand manner. However, ceramics-related museums often provide important information such as the shape and production process of ceramics to visitors in static images such as photography, illustration, and 2D graphics. Therefore, in this study, in order to increase the accuracy of information recognition on ceramic cultural properties, two versions of the process of making 元 Peony Flower Patterns Blue and White porcelain at the 景徳鎭 Ceramic Museum in Gyeongdeokjin, China were provided. The first version provided the production process with key images without movement, and the second version provided the production process using motion graphics. The survey was conducted on 65 Korean adults. As a result, it was confirmed that the content design guiding the production process of Chinese ceramic cultural properties using motion graphics was very effective in delivering information. Visitors who watched dynamic motion graphics showed a higher level of information perception overall than those who watched fixed images. In particular, it was necessary to understand a complex stage in the glaze painting stage, and the difference in the level of information perception that accurately understood this had distinct characteristics. Through the development of content design that guides the production process of Chinese ceramic cultural properties using motion graphics, you will be able to gain more knowledge and appreciation through moving visual images provided with motion graphics rather than stationary images. Therefore, it is expected that research on using various cultural properties’ contents and motion graphics will be actively conducted.

MicroRNAs (miRNAs) are endogenous non-coding genes that participate in post-transcription regulation by either degrading mRNA or blocking its translation. It is considered to be very important in regulating insect development and metamorphosis. Insects are the largest group of animals and are extremely valuable in biological and agriculture research. Insects are also important pests to human health and agriculture, and efforts are necessary protect both humans and plants from disease and damage. Despite their importance, insects lag behind mammals, nematodes, and plants in miRNA research. At present, only 279 insect miRNAs have been identified from Drosophila melanogaster, Anopheles gambiae, Apis mellifera, Bombyx mori, and D. pseudoobscura in miRBase, and most of these miRNAs were computationally predicted without experimental validation. Functional analysis of insect miRNAs has only been conducted in D. melanogaster.

( Wen-luh Huang ),( Jia-jyun Huang ),( Chih-cheng Pai ),( Zi-yuan Xue ),( Yu-hsuan Wu ) 한국농업기계학회 2018 한국농업기계학회 학술발표논문집 Vol.23 No.1

The traditional process of cabbage roll at present is to use the manpower to excavate cabbage stem, to invert the hot water to heat(70-80℃) to shell leaf and cool it down, patting the cabbage leaf stem and then put the stuffing on the leaf, rolling the leaf and tying a knot by hand finally. Most processes of production are hand-made. The human resource cost is high and the production capacity is limited. Therefore, our project is designed to develop and research for the tying and bundling machinery for cabbage roll. Our machinery is mainly composed of U-type platform for cabbage roll, hook for calabash melon wire, adjustable varying speed motor, insert machinery, Single acting cylinder,Programmable Logic Controller(PLC) and others elements. According to our test results, the embedded machinery operates fine, not only bundling a single cabbage spent less than 6 seconds, but also passing the 6 hours cooking test. The wire lead won’t be dropout. The bundled cabbage roll achieved the same standard specification of cabbage roll that the 7-11 convenience stores’re selling now. At the same time, we tried different wire materials and different process (bundling and tying) to make questionnaire. According to our statistical results, no matter the texture, process(bundling and tying)and taste, the bundling process is all better than the traditional tying process, and preference of wires materials shows the most respondents choose the calabash melon which account for 45.9%, the second and third choice is konjac jelly, leek(16.5%)and Dried bamboo shoot (15.3%), others account for 5.8%. Finally we find that this embedded bundling machinery’s feature and performance will satisfy with the Mechanization demands for the food factory.

Hua-Xing Huang,Liang-Lan Shen,Hai-Yan Huang,Li-Hua Zhao,Feng Xu,Dong-Mei Zhang,Xiu-Lin Zhang,Tong Chen,Xue-Qin Wang,Yan Xie,Jian-Bin Su 대한당뇨병학회 2021 Diabetes and Metabolism Journal Vol.45 No.6

Background: Type 2 diabetes mellitus (T2DM) is characterized by elevated fasting glucagon and impaired suppression of postprandial glucagon secretion, which may participate in diabetic complications. Therefore, we investigated the associations of plasma glucagon with estimated glomerular filtration rate (eGFR), albuminuria and diabetic kidney disease (DKD) in T2DM patients.Methods: Fasting glucagon and postchallenge glucagon (assessed by area under the glucagon curve [AUCgla]) levels were determined during oral glucose tolerance tests. Patients with an eGFR <60 mL/min/1.73 m2 and/or a urinary albumin-to-creatinine ratio (UACR) ≥30 mg/g who presented with diabetic retinopathy were identified as having DKD.Results: Of the 2,436 recruited patients, fasting glucagon was correlated with eGFR and UACR (r=–0.112 and r=0.157, respectively; P<0.001), and AUCgla was also correlated with eGFR and UACR (r=–0.267 and r=0.234, respectively; P<0.001). Moreover, 31.7% (n=771) presented with DKD; the prevalence of DKD was 27.3%, 27.6%, 32.5%, and 39.2% in the first (Q1), second (Q2), third (Q3), and fourth quartile (Q4) of fasting glucagon, respectively; and the corresponding prevalence for AUCgla was 25.9%, 22.7%, 33.7%, and 44.4%, respectively. Furthermore, after adjusting for other clinical covariates, the adjusted odds ratios (ORs; 95% confidence intervals) for DKD in Q2, Q3, and Q4 versus Q1 of fasting glucagon were 0.946 (0.697 to 1.284), 1.209 (0.895 to 1.634), and 1.521 (1.129 to 2.049), respectively; the corresponding ORs of AUCgla were 0.825 (0.611 to 1.114), 1.323 (0.989 to 1.769), and 2.066 (1.546 to 2.760), respectively. Additionally, when we restricted our analysis in patients with glycosylated hemoglobin <7.0% (n=471), we found fasting glucagon and AUCgla were still independently associated with DKD.Conclusion: Both increased fasting and postchallenge glucagon levels were independently associated with DKD in T2DM patients.
