Development of a New Direct Marketing Channel in the Chinese Rural Market: The Case of Hongfu Fertilizer Company

Dao-sheng Li,홍진환 한국마케팅학회 2013 ASIA MARKETING JOURNAL Vol.15 No.2

Distribution channel decisions involve long-term commitments with other firms that are very difficult to change or replace. In particular, marketing channel decisions in emerging markets are much more complicated due to unfamiliar conditions and problems such as lack of market data and distribution systems. Therefore, when a company considers changing or introducing a marketing channel in an area, it is much more difficult to judge its effectiveness in an emerging market than in a developed market. In this study, we investigate the development process of a new direct marketing channel of Hongfu Fertilizer Company (hereafter Hongfu), a medium-sized Chinese fertilizer manufacturer, and propose an approach to test the feasibility of this new marketing channel in the Chinese rural market. We measure the effectiveness of Hongfu’s new marketing channel from two perspectives: i) from customers’ perspective through direct responses of farmers, which showed that a new channel can increase the convenience and lower the purchasing costs for the farmers, and ii) from the company’s perspective, by calculating the incremental profit of the company using the expansion factor (T/Q) method, which suggested that the execution of Hongfu’s strategy to expand a new marketing channel will result in an increase in profits. The results of this study contribute to the development of a methodology to test the feasibility of a new direct marketing channel in the emerging markets such as the Chinese rural market. Traditional and indirect distribution channels in emerging markets are generally not very efficient and difficult to change. Especially, in emerging markets, like the Chinese rural market, the methods of testing channel feasibility must be different from that of developed markets. Considering market situations, market experiments can be more effective then systematic market surveys in testing channel feasibility in emerging markets. This study implies that managers must learn to cope with a transition from the traditional marketing channels in emerging markets. With the development in farmers’ understanding of marketing concept, the transition from traditional marketing channel is unavoidable for all firms. Farmers in China are generally very conservative, however, their buying behaviors are changing. Therefore, fertilizer companies should try to adjust in accordance with farmers’ demand characteristics that the efforts to meet the economic needs of farmers with new marketing channels as well as trust building are critical in the near future.

Impact of Pursuing Goals on Customer Channel Preference: Mediating Effects of Product Utility and Process Utility

Li, Dao-sheng,Lee, Hyunjoung,Hong, Jinhwan Korean Marketing Association 2014 ASIA MARKETING JOURNAL Vol.16 No.2

This paper explores the influence of pursuing goals on customer channel preference in Chinese rural market. With the rapid change in distribution channels and increase in multi-channels, it is necessary to understand the preference for channel choice as well as product choice. This study empirically validated the conceptual framework of the relationship between the pursuing goals and customer channel choice proposed by Balasubramanian, Raghunathan, and Mahajan (2005). Based on the survey data of 232 fertilizer customers in Chinese rural market, this study explores how economic, social, and psychological pursuing goals can impact customer channel preference by mediating variables of product utility and process utility. The results indicate that pursuing goals positively related with product utility and process utility, and product / process utility can mediate the relationship between pursuing goals and customer channel preference positively. Consequently, we can conclude that customers' economic-social-psychological pursuing goals can directly influence customer channel preference via their purchase process utility and product utility. This result also implies that product utility is effective on process utility during consumer's buying decision making, and process utility and product utility are not mutually independent. Therefore, purchase process utility is a "latent driving force" on customer's channel choice decision.

A cDNA encoding a cysteine protease inhibitor (CPI) was isolated from the cDNA library of clamworm Perinereis aibuhitensis Grube. The deduced amino acid sequence analysis showed that the protein had 51%, 48%, and 48% identity with Zgc: 153129 from Danio rerio, cystatin B from Theromyzon tessulatum, and the ChainA, stefin B tetramer from Homo sapiens, respectively. The gene was cloned into the intracellular expression vector pET-15b and expressed in Escherichia coli. The recombinant CPI (PA-CPI) was purified by affinity chromatography on Nicharged resin and ion-exchange chromatography on DEAE-Sepharose FF. The relative molecular mass of PACPI was 16 kDa as deduced by SDS-PAGE. Activity analysis showed that the recombinant protein could inhibit the proteolytic activity of papain. A constitutive and secretive expression vector was also constructed, and the cDNA encoding CPI was subcloned into the vector for extracellular expression. Western blotting analysis results showed that the PA-CPI was secreted into the medium. Bioassay demonstrated that E. coli DH5α harboring pUC18ompAcat-CPI showed a significant difference in mortality to the Asian longhorned beetle Anoplophora glabripennis compared with untransformed E. coli DH5α and control.

Ma, Ying,Mao, Rui,Feng, Sheng‐,Hui,Gong, Dao‐,Yi,Kim, Seong‐,Joong John Wiley Sons, Ltd 2017 International journal of climatology Vol.37 No.7

<P><B>ABSTRACT</B></P><P>Wind chill temperature (WCT) describes the joint effect of wind velocity and air temperature on exposed body skin and could support policymakers in designing plans to reduce the risks of notably cold and windy weather. This study examined winter WCT over Northern Asia during 1973–2013 by analysing <I>in situ</I> station data. The winter WCT warming rate over the Tibetan Plateau (TP) slowed during 1999–2013 (−0.04 °C decade<SUP>−1</SUP>) compared with that of during 1973–1998 (0.67 °C decade<SUP>−1</SUP>). The winter WCT warming hiatus has also been observed in the remainder of Northern Asia with trends of 1.11 °C decade<SUP>−1</SUP> during 1973–1998 but −1.02 °C decade<SUP>−1</SUP> during 1999–2013, except for the Far East (FE) of Russia, where the winter WCT has continued to heat up during both the earlier period of 1973–1998 (0.54 °C decade<SUP>−1</SUP>) and the recent period of 1999–2013 (0.75 °C decade<SUP>−1</SUP>). The results indicate that the influence of temperature on winter WCT is greater than that of wind speed over Northern Asia. Atmospheric circulation changes associated with air temperature and wind speed were analysed to identify the causes for the warming hiatus of winter WCT over Northern Asia. The distributions of sea‐level pressure and 500‐hPa height anomalies during 1999–2013 transported cold air from the high latitudes to middle latitudes, resulting in low air temperature over Northern Asia except for the FE of Russia. Over the TP, the increase in wind speed offset the increase in air temperature during 1999–2013. For the FE, the southerly wind from the Western Pacific drove the temperature up during the 1999–2013 period through warm advection.</P>

Yu-shuai Wang,Min-zhe Fang,Sheng-dao Zheng,조진경,이태후 한국식품과학회 2021 Food Science and Biotechnology Vol.30 No.10

Tea is one of the most widely consumed aromaticbeverages in the world because of its taste and flavor,as well as due to many potential health beneficial properties. Metabolomics focuses on an in-depth analysis of allmetabolites in living organisms. In this study, 29 primarymetabolites and 25 secondary metabolites were identifiedusing GC/MS and UPLC-QTOF/MS, respectively. Further,PCA analysis showed conspicuous discrimination for theten varieties of green tea with metabolite profiling. Amongthem, organic acids, amino acids, flavan-3-ols, and flavonolglycosides varied greatly through checking the VIP valuesof the PLS-DA model. Moreover, the intrinsic and/orextrinsic factors characterizing each type of green tea werealso discussed. The chemical component marker derivedhere should be used as an important detection index, whileevaluating the tea quality, as well as while establishing thetea quality standard.

Crack‑free TiO2 films prepared by adjusting processing parameters via liquid phase deposition technique

Jie Li,Hai‑Yan Xu,Ai‑Guo Wang,Feng‑Jun Zhang,Dao‑Sheng Sun,Won‑Chun Oh 한국세라믹학회 2020 한국세라믹학회지 Vol.57 No.2

TiO2 thin films with controllable morphology and grain size were prepared via a liquid phase deposition (LPD) technique. The effects of the processing parameters including the ( NH4)2TiF6 concentration, solution pH, and ( NH4)2TiF6:H3BO3 molar ratio on the grain size and morphology of the films were investigated. The prepared samples were characterized by X-ray diffraction, scanning electron microscopy, and ultraviolet–visible spectroscopy. The results showed that the deposition parameters significantly affected the growth and nucleation velocities of the crystalline grains, which resulted in the formation of TiO2 films with different morphologies and grain sizes. The capillary stress among the grains of the film, which resulted in the cracking of the film, depended on the size of the grains. Thus, the cracking of the LPD-derived TiO2 films could be mitigated by adjusting the deposition parameters.

Hua-Shuai Gao,Zhi-Min Zong,Zheng Yang,Dao-Guang Teng,Xiu-Hua Sun,Li Yan,Xian-Yong Wei,Qing-Jie Guo,Tian-Sheng Zhao,Hong-Cun Bai 한국화학공학회 2020 Korean Journal of Chemical Engineering Vol.37 No.5

Low-temperature coal tar (LTCT) is a sticky liquid mixture produced mainly from coal pyrolysis, which contains various value-added chemicals (VACs). Liquid-liquid extraction is considered as one of the green and effective ways to explore the organic composition and separate the VACs from LTCT. Herein, petroleum ether, methanol, and carbon disulfide were used to extract arenols from a LTCT. As a result, the relative content and absolute content of arenols extracted from the LTCT are ca. 96.3% and 85.9%, respectively. Among them, p-cresol is predominant, accounting for 22.2%. The isolated contents of arenols are up to 84.6%. Moreover, a kilogram-scale operation was carried out under the same conditions, which offers a potential application in industrial production.

A yellow pigmented, Gram-stain-negative, aerobic bacterium designated A5.7T was studied to evaluate the taxonomic position following the modern polyphasic approach. The strain was isolated from sediments near Zhairuo Island, which is situated in the East China Sea. Cells were non-spore forming rods without flagella but showed motility by gliding. Growth was observed at 15–35°C (optimum 28°C), pH 6.0–9.0 (optimum pH 6.5) and 0–2% (w/v) NaCl (optimum 0–0.5%) in LB broth. The major respiratory quinone of A5.7T was menaquinone 6. The major polar lipid of A5.7T was phosphatidylethanolamine and the predominant fatty acids (> 5%) were iso-C15:0, iso-C17:0 3-OH, C15:1 ω6c, iso-C15:0 3-OH, iso-C15:1 G, summed feature 3 (C16:1 ω7c and/or C16:1 ω6c) and summed feature 9 (iso-C17:1 ω9c and/or C16:0 10-methyl). Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate belongs to the genus Flavobacterium and shares the highest sequence similarities with Flavobacterium sharifuzzamanii A7.6T (98.5%), Flavobacterium tistrianum GB 56.1T (98.3%), Flavobacterium nitrogenifigens NXU-44T (97.8%), Flavobacterium anhuiense D3T (97.6%), Flavobacterium ginsenosidimutans THG 01T (97.6%), and Flavobacterium foetidum CJ42T (97.6%). Digital DNA-DNA hybridization and average nucleotide identity values between the strain and its closest phylogenetic neighbors showed the ranges from 19.6 to 34.1% and 73.7 to 87.9%, respectively. Therefore, based on polyphasic characteristics, strain A5.7T represents a novel species of the genus Flavobacterium for which the name Flavobacterium zhairuonensis sp. nov. is proposed. The type strain is A5.7T (= KCTC 62406T = MCCC 1K03494T).

Xu Hai-Yan,Yang Yi Cai,Li Dong-Cai,Wu Ran Ran,Wang Ai-Guo,Sun Dao-Sheng,Zhang Feng-Jun,오원춘 한국세라믹학회 2023 한국세라믹학회지 Vol.60 No.3

Heavy metal ion pollution of water resources is becoming increasingly serious, and adsorption is one of the most effective strategies for removing heavy metal ions. In the paper, hydrated hydrogen sodium vanadium oxide (HNaV 6O164H2O) fi lm developed for heavy metal ion adsorption was prepared directly via a low-temperature liquid-phase deposition approach. The prepared film shows an interesting porous flower-like morphology and has large spacing ( d = 10.87 Å). The highest adsorption capacity of the obtained HNaV 6O164H2O fi lm for Pb 2+, Cu 2+, Cd 2+ and Mn 2+ is 513 mg/g (2565 mg/m 2), 430 mg/g (2150 mg/m 2), 134 mg/g (875 mg/m 2) and 175 mg/g (670 mg/m 2), respectively. The adsorption percentage of the sample decreased from 92.2 to 86.3% after 4 cycles. The adsorption process follows the Langmuir adsorption isotherm and the pseudo second-order dynamic model, indicating that heavy metal ion adsorption by the fi lm is a single molecular layer chemical adsorption. In combination with various characterizations and comparison tests of samples after adsorption, the adsorption mechanisms include surface electrostatic attraction, complexation, and cation exchange. The results indicate that the fi lm is a potential material to remove heavy metal ions from the aqueous solution.

Wang Xu-Dong,Xu Hai-Yan,Zhang Feng-Jun,Li Dong-Cai,Wang Ai-Guo,Sun Dao-Sheng,오원춘 한국세라믹학회 2020 한국세라믹학회지 Vol.57 No.4

The eff ect of impurities in coal gangue on the sintering and properties (porosity and compressive strength) of porous cordierite ceramics has been investigated by adjusting the amount of impurities by controlling the acid–gangue ratio during acid leaching. The sintering behavior and microstructure of the porous ceramics have been characterized via X-ray diff ractometry and scanning electron microscopy. The eff ects of both the acid–gangue ratio and sintering temperature on the porosity and compressive strength have been also investigated. The results indicated that both porosity and compressive strength of the porous cordierite ceramics prepared using acid-leached coal gangue were evidently improved. The content of the impurities in coal gangue was adjusted via acid leaching by controlling the acid–gangue ratio. The appropriate content of impurities in coal gangue facilitated the sintering process and improved the porosity and compressive strength of the obtained porous cordierite ceramics.
