A Study on Success Factors in the 6th Industrialization of Agriculture in Korea and China
Ming-Sheng Zhu,Jin-Sup Jung 한국무역연구원 2017 무역연구 Vol.13 No.4
Rural communities in both Korea and China have faced important negative conditions, such as a population decrease, aging, and the increasing income gap between urban and rural areas. To overcome these problems, a new change is needed in rural areas. In recent years, the 6th industrialization of agriculture, which seeks the convergence of the primary, secondary, and tertiary industries to revitalize agriculture and rural villages, has attracted considerable attention as an alternative. Meanwhile, Korea and China have plentiful humanistic resources. However, there are few studies on how humanistic resources affect the success in the 6th industrialization of agriculture. The goal of this study it to carry out empirical tests on Korea and China, using key successful factors―technology, manpower, market expansion, government support, linkages among industrial subjects―for the 6th industrialization of agriculture and find moderating effects of physical humanistic resources. Results suggest some valuable implications, and differences between Korea and China.

Background: Although Becker`s nevus (BN) is a relatively common disease, the systematic studies of clinicopathological and immunohistochemical results are poorly reported. Objective: To investigate the clinicopathological features and immunohistochemical alterations of keratinocyte proliferation, melanocyte density, smooth muscle hyperplasia and nerve fiber distribution in BN. Methods: Clinical and pathological data were collected in 60 newly-diagnosed BN cases. Immunohistochemical stain of Ki-67, Melan-A, keratin 15, smooth muscle actin and protein gene product 9.5 was performed in 21 cases. Results: The median diagnostic and onset age was 17 and 12 years, respectively. Skin lesions usually appeared on the upper trunk and upper limbs. The pathological features included the rete ridge elongation and fusion and basal hyperpigmentation. Epidermal Ki-67, Melan-A and keratin 15 expression and dermal nerve fiber length were significantly higher in lesional and perilesional skin than in normal skin (p<0.05∼0.01), while smooth muscle actin expression was upregulated only in skin lesion (p<0.05). Conclusion: Although the clinical diagnosis of BN is often straightforward, histopathology is helpful to differentiate from other pigmentary disorders. The hyperproliferation of keratinocytes, melanocytes, arrector pili muscle and dermal nerve fibers could be involved in the patho-genesis of BN. (Ann Dermatol 28(6) 697∼703, 2016)

In order to study the biological function of gapdh gene in yak, and prove whether the gapdh gene was a useful intra-reference gene that can be given an important role in molecular biology research of yak, the cDNA sequence encoding glyceraldehyde-3-phosphate dehydrogenase from yak was cloned by the RT-PCR method using gene specific PCR primers. The sequence results indicated that the cloned cDNA fragment (1,008 bp) contained a 1,002 bp open reading frame, encoding 333 amino acids (AAs) with a molecular mass of 35.753 kDa. The deduced amino acids sequence showed a high level of sequence identity to Bos Taurus (99.70%), Xenopus laevis (94.29%), Homo sapiens (97.01%), Mus musculus (97.90%) and Sus scrofa (98.20%). The expression of yak's gapdh gene in heart, spleen, kidney and brain tissues was also detected; the results showed that the gapdh gene was expressed in all these tissues. Further analysis of yak GAPDH amino acid sequence implied that it contained a complete glyceraldehyde-3-phosphate dehydrogenase active site (ASCTTNCL) which ranged from 148 to 155 amino acid residues. It also contained two conserved domains, a NAD binding domain in its N-terminal and a complete catalytic domain of sugar transport in its C-terminal. The phylogenetic analysis showed that yak and Bos taurus were the closest species. The prediction of secondary structures indicated that GAPDH of yak had a similar secondary structure to other isolated GAPDH. The results of this study suggested that the gapdh gene of yak was similar to other species and could be used as the intra-reference to analyze the expression of other genes in yak.

<P>2-Aminoindan-2-phosphonic acid (AIP), a specific competitive phenylalanine ammonia lyase (PAL) inhibitor was applied to a suspension cell culture of Cistanche deserticola. The effects of AIP treatment on cell growth, PAL activity, contents and yields of total phenolic compound, salidroside and four phenylethanoid glycosides (PheGs) are investigated. The results demonstrated that, 0.5 and 2.0 μM AIP treatments had similar effects on the measurements investigated in this study. AIP treatment resulted in significant decreases in PAL activity, total phenolic compounds content, and PheGs content. Linear regression analysis showed that PAL activity had a high correlation coefficient with the total phenolic compound content and the four PheGs contents. Total PAL activity-time area under curve (AUC) had a high correlation coefficient with the total phenolic compound yield and the yields of five tested compounds in untreated cell samples. In AIP-treated cells, total PAL activity-time AUC retained a high correlation with the total phenolic compound yield and the yields of three tested compounds, echinacoside, acteoside, and tubuloside A, but not salidroside and cistanoside A. The difference could be caused by the different biosynthetic origins of each of the tested compounds. These results demonstrate the important role of PAL in the biosynthesis of PheGs in the suspension cell culture of C. deserticola.</P>

High temperature preheated air and steam as gasifying agent and coal gasification was performed in a pressurized turbulent circulating fluidized bed (CFB) gasification pilot plant to investigate the pressurized gasification process and estimate its potential. Within the scope of this paper this test facility as well as its operation behavior was described. Furthermore, the parameter pressure has been investigated regarding its influence on the syngas composition and was presented and discussed in the following. The results show that the gasification quality is improved at higher pressure because of the better fluidization in the reactor. Coal gasification at a higher pressure shows advantages in lower heat value and carbon conversion. With the gasifier pressure increased from 0.1MPa to 0.3MPa, the gas heating value is increased by 15%. Increasing the gasifier pressure would increase the carbon conversion from 57.52% to 76.76%. Also, the dry gas yield and efficiency of cold gas increase little with the increase of the gasifier pressure. The operating parameter of pressure exists at optimum operating range for this specific CFB coal gasification process.
