        The development of ICT technology has created new channels for product sales and promotion, which not only make information accessible to customers as easy as possible, but also provide consumers with much more absolute and comparative information. Modern consumers are exposed so many shopping channels currently, especially mobile-based channels have grown significantly and have become the center of the market. It is true that mobile shopping has led the growth of overall online shopping with the recent development of mobile devices such as smartphones and related software. The importance of strengthening corporate competitiveness and mobile-based management strategies through on line channels continues to increase. At this point, this study attempted to investigate the influencing factors by focusing on the entire distribution channel and mobile shopping channels. As most of previous studies were focused on Internet shopping malls or specific channels, So the research on mobile channels can be judged to be timely and appropriate. Furthermore, it can be said that mobile shopping channels are now presenting empirical implications. In conclusion, it provides practical implications to examine the management strategy of mobile shopping channels from the perspective of consumer value.

        Designing and producing a low-cost, high-current-density electrode with good electrocatalytic activity for the oxygen evolution reaction (OER) is still a major challenge for the industrial hydrogen energy economy. In this study, nanostructured Fe-doped CuCo(OH)2 was discovered to be a precedent electrocatalyst for OER with low overpotential, low Tafel slope, good durability, and high electrochemically active surface sites at reduced mass loadings. Fe-doped CuCo(OH)2 nanosheets are made using a hydrothermal synthesis process. These nanosheets are clumped together to form a highly open hierarchical structure. When used as an electrocatalyst, the Fe-doped CuCo(OH)2 nanosheets required an overpotential of 260 mV to reach a current density of 50 mA cm−2. Also, it showed a small Tafel slope of 72.9 mV dec−1, and superior stability while catalyzing the generation of O2 continuously for 20 hours. The Fe-doped CuCo(OH)2 was found to have a large number of active sites which provide hierarchical and stable transfer routes for both electrolyte ions and electrons, resulting in exceptional OER performance.

        분화국화 ‘솔라에그(등록번호 8569)’는 2015년 경상남도농 업기술원 화훼연구소에서 분홍색 ‘포인트에그’를 감마선 처리 를 하여 육성하였다. 특성검정과 형질 안정성은 2017년에서 2018년까지 3회를 수행하였다. ‘솔라에그’는 분홍색 꽃잎(54D) 과 적자색 중심부(59B)를 가진 ‘아네모네’ 형태이다. 꽃과 잎 색깔과 모양에서는 ‘솔라에그’와 ‘포인트에그’ 간의 차이는 거 의 없었다. ‘솔라에그’의 식물체와 개화 연구에서 조명과 억제 재배를 했을 때 약 42일로 개화소요시간은 비슷했다. 그러나 초장, 꽃 크기, 꽃 중심부 크기와 착화수에서 ‘포인트에그’와 비교했을 때 차이가 있었다. 특히, 자연재배조건에서 꽃 크기 는 4cm으로 대조품종과 비교했을 때 컸다. 국화 품종에서는 꽃의 크기가 상업적으로 중요한 형질이다. ‘솔라에그’의 표현 형과 개화기 연구와 비교하여 배수성, RAPD, 세포 크기 및 수 분석을 하였다. 이들 결과에서는 표현형의 변화는 작은 유전 적 변이와 세포 분열 증가와 관련이 있을 것이라고 추정하고 있다. 중형 크기의 ‘솔라에그’는 분화국화로 이용되며 농가의 평균소득 증대를 기대할 수 있다.

        비모란 선인장 ‘Ahwang’ 품종이 2016년에 국립원예특작과 학원에서 육성되었다. 증식력이 우수한 밝은 황색 ‘Ahwang’ 품종 육성을 위해서, 황색 ‘Hwangun’품종을 모본으로, 황색 ‘0930001’ 계통을 부본으로 하여 2012년 6월 25일에 교배하였다. 어린 비모란 선인장을 2014년 이전에 삼각주에 2번 접목하여 계통을 양성하였으며 2014년부터 2016년까지 총 3회에 걸쳐 생육특성을 조사하였다. ‘Ahwang’ 품종의 모구는 편원형 모양에 황색 구색(Y9A)이다. 모구는 평균 8.6개의 능(rip)과 2.7mm의 짧은 직립형 회색 가시를 가지고 있고 혹(tubercle)이 돌출된 형태를 띠고 있다. 10개월 재배 후 ‘Ahwang’ 품종의 구직경은 44.5mm였으며 자구는 평균 26.9개가 생성되었다. ‘Ahwang’ 품종은 모구 능마다 황색의 자구가 3-4개가 착생되었다. 2016년 육성계통 평가회에서 ‘Ahwang’ 품종은 기호도 점수 3.9을 받았다. 이 품종은 2018년 5월 16일 국립종자원에 등록되었으며 식물신품종보호법에 의해 품종보호(등록번호 7193)를 받게 되었다.

        The purpose of this study was to develop synbiotic materials and to apply them to the puffed grain products using electrostatic spraying technology. Lactic acid bacteria were isolated from Kimchi and selected through tests of acid resistance, bile salt resistance and γ-aminobutyric acid (GABA) content. The isolated Lactobacillus brevis CFM21 produced highest GABA production up to a concentration of 926.42 μg/mL when grown in MRS broth containing 0.8% MSG. The possibility of coated grains as a prebiotic material was evaluated Confocal laser scanning micro scopy (CLSM). Rice bran extract containing 2% dextrose, 2% soytone, 0.2% potassium chloride, 0.6% MSG was produced 524.77 μg/mL of GABA. Citrus sinensis oil showed the highest antibacterial activity against Clostridium perfringens Electrostatic spray showed much higher effectiveness than conventional spray in coating the puffed grain product through CLSM. Applying Rice bran culture and Citrus sinensis oil to puffed grain product using electrostatic spray could contribute to promote intestinal health of consumers.

        Online search advertising (aka, sponsored or paid search advertising) is a technology that any matched advertisement is displayed on Web pages as online users’ query results from search engines and Web portals (e.g., Google, Bing, Baidu, Naver, and Yahoo!). In specific, after online users type search keywords on the search box (at this stage, online users become searchers), search engines match users’ query texts to phrases included in search advertisement. Then, if an advertiser’s investment on her/his search advertisement is high enough, the advertisement is likely to be displayed on a search engine results (called “impression”) (Hanson and Kalyanam 2007; Jansen et al. 2009; Jansen and Clark 2017; Moore, Stammerjohan, and Coulter 2005). Once a searcher clicks a displayed advertisement and arrives on the advertiser’s landing page, s/he becomes a visitor by clicking the impression. As benefits of utilizing search keywords, online search advertising can reduce search costs and increase information accessibility by potential customers. In addition, because online search advertising provides relevant search results based on the users’ own queries, it is considered less intrusive than banner advertisement and widely used by many marketers (Ghose and Yang 2009; Johnson, Bruner, and Kumar 2006; Quinton and Khan 2009; Rangaswamy, Giles, and Seres 2009; Yang and Ghose 2010).
