In order to identify effective approaches for creating more viral Facebook posts, this research conducted an empirical content analysis of leading Korean brands' Facebook fan-pages (Samsung Mobile, SK Telecom, Kia Motors, and POSCO). Their distinctive visual storytelling and communication patterns were investigated as effective user engagement triggers. Through analysis of the research results, it was statistically proved that the different industrial attributes of the four brands, which are primarily characterized by their product (or service) types, affect their Facebook posting patterns by showing different engaging rates (measured by like, comment, and share metrics). In addition, the user engagement rates of the posts were influenced by their visual storytelling factors (i.e. ad objective, value scale, and visual media types). In line with these statistical findings, the distinctive visual storytelling strategies of the four brands were identified. Moreover, competitive and uncompetitive visual storytelling tactics were suggested according to the ad objectives and visual media types on Facebook.

Colletotrichum acutatum J. H. Simmonds is an important fungal pathogen that causes anthracnose disease in crops. In this study, 59 C. acutatum isolates from regions in South Korea were collected and phenotypically compared. The average colony diameters of isolates from Gyeongsangbuk-do, Chungcheongbuk-do, and Gangwon-do were 4.36 cm, 4.24 cm, and 4.38 cm, respectively, following 6 days of growth on V8 juice agar. The average conidium concentrations of the isolates from each province were 14.43, 12.83, and 10.17 × 104/mL after 7 days of growth on V8A. Amplified fragment length polymorphism(AFLP) analysis using three primer pairs identified 5 polymorphic bands and 56 monomorphic bands. Two polymorphic bands were identified using the E-ACC/M-CTT primer pair, one polymorphic band was identified using the E-ACG/M-CTG primer pair, and two polymorphic bands were identified using the E-ACG/M-CTT primer pair. A dendrogram was constructed using the AFLP data, and four clusters were identified.

Postharvest apple rot causes severe economic losses and lowers apple quality, and is one of the most important limiting factors of apple exports. Apples with rot symptoms were sampled from Geochang, South Korea. Isolation of the causal fungus was performed by culturing small pieces of diseased tissues on potato dextrose agar. Two different rot genera, Fusarium and Alternaria, were identified according to their morphological characteristics. To confirm the identity of the causal fungus, we sequenced the DNA of the complete internal transcribed spacer(ITS) rDNA gene region and translation elongation factor 1-alpha(EF1-α) region. Koch’s postulates were supported by pathogenicity tests conducted on apple fruit. Based on mycological characteristics, molecular identification, and pathogenicity tests, the two fungi were identified as Fusarium tricinctum and Alternaria alternata. To the best of our knowledge, this is the first report of postharvest apple rot caused by F. tricinctum and A. alternata in South Korea.

We propose a custom analysis technique for the dark field (DF) image based on transmission electron microscopy (TEM). The custom analysis technique is developed based on the DigitalMicrograph® (DM) script language embedded in the Gatan digital microscopy software, which is used as the operational software for most TEM instruments. The developed software automatically scans an electron beam across a TEM sample and records a series of electron diffraction patterns. The recorded electron diffraction patterns provide DF and ADF images based on digital image processing. An experimental electron diffraction pattern is recorded from a IrMn polycrystal consisting of fine nanograins in order to test the proposed software. We demonstrate that the developed image processing technique well resolves nanograins of ~ 5 nm in diameter.

The formation mechanism and photocatalytic properties of a multiwalled carbon nanotube (MWCNT)/TiO2- based nanotube (TNTs) composite are investigated. The CNT/TNT composite is synthesized via a solution chemical route. It is confirmed that this 1-D nanotube composite has a core-shell nanotubular structure, where the TNT surrounds the CNT core. The photocatalytic activity investigated based on the methylene blue degradation test is superior to that of with pure TNT. The CNTs play two important roles in enhancing the photocatalytic activity. One is to act as a template to form the core-shell structure while titanate nanosheets are converted into nanotubes. The other is to act as an electron reservoir that facilitates charge separation and electron transfer from the TNT, thus decreasing the electronhole recombination efficiency.

직장 내 성차별은 많은 나라에서 아직도 큰 사회적 이슈이고 전 세계적으로 국제기관과 각국 정 부들은 이를 줄이기 위해 많은 노력을 기울이고 있다. 기업들 또한 직장 내 성차별을 줄이는 것을 사회적 책임 활동의 하나로 여기고 점차 많은 관심을 보이고 있다. 이러한 추세를 바탕으로 본 연 구는 외국인 소유가 직장 내 여성차별에 어떠한 영향을 미치는지를 조사한다. 한국직업능력개발원 에서 구축한 인적자본 기업패널 자료를 분석하여 본 연구는 외국인이 소유권을 보유하고 있는 회사 는 한국인만이 소유권을 보유하고 있는 회사에 비해 좀 더 많은 여성 인력을 채용하고 있음을 밝혔 다. 또한 외국인이 소유권을 보유하고 있는 회사는 상장회사일 경우 비상장회사에 비해 정규직 여 성채용에 더 적극적임을 발견했다. 이러한 연구결과는 외국인 투자가 현지국의 직장 내 성차별이라 는 사회적 이슈에 미치는 영향을 보여줌으로 외국인 투자와 성차별에 관한 연구분야에 유용한 시사 점을 제공하고 있다.

We investigate the solar cycle variation of microwave and extreme ultraviolet (EUV) intensity in latitude to compare microwave polar brightening (MPB) with the EUV polar coronal hole (CH). For this study, we used the full-sun images observed in 17 GHz of the Nobeyama Radioheliograph from 1992 July to 2016 November and in two EUV channels of the Atmospheric Imaging Assembly (AIA) 193 A° and 171 A° on the Solar Dynamics Observatory (SDO) from 2011 January to 2016 November. As a result, we found that the polar intensity in EUV is anti-correlated with the polar intensity in microwave. Since the depression of EUV intensity in the pole is mostly owing to the CH appearance and continuation there, the anti-correlation in the intensity implies the intimate association between the polar CH and the MPB. Considering the report of Gopalswamy et al. (1999) that the enhanced microwave brightness in the CH is seen above the enhanced photospheric magnetic field, we suggest that the pole area during the solar minimum has a stronger magnetic field than the quiet sun level and such a strong field in the pole results in the formation of the polar CH. The emission mechanism of the MPB and the physical link with the polar CH are not still fully understood. It is necessary to investigate the MPB using high resolution microwave imaging data, which can be obtained by the high performance large-array radio observatories such as the ALMA project.

This study was aimed to evaluate the dose-response the effects of nano-encapsulated conjugated linoleic acids(CLAs) on in vitro ruminal fermentation profiles. A fistulated Holstein cow was used as a donor of rumen fluid. Nano-encapsulated CLAs(LF, 5% of nano-encapsulated CLA-FFA; HF, 10% of nano-encapsulated CLA-FFA; LT, 5% of nano-encapsulated CLA-TG; HT, 10% of nano-encapsulated CLA-TG) were added to the in vitro ruminal fermentation experiment. In the in vitro ruminal incubation test, the total gas production on incubation with nano-encapsulated CLAs was increased significantly according to the incubation time, compared with the control(p<0.05). The tVFA concentrations on addition of LF and HT were significantly higher than that of the control(p<0.05). Thus, nano-encapsulated CLAs might improve the ruminal fermentation characteristics without adverse effects on the incubation process. In addition, the population of Butyrivibrio fibrisolvens which is closely related to ruminal biohydrogenation was increased by adding HT, while decreased by adding LF at 12 h incubation. These results showed that nano-encapsulated CLA-FFA could be applied to enhance CLA levels in ruminants by maintaining the stability of CLA without causing adverse effects on ruminal fermentation profiles considering the optimal dosage.

Unidirectionally solidified TiAl alloys were prepared by optically-heated floating zone method at growth rates of 10 to 70 mm/h in flowing argon. The microstructures and tensile properties of these crystal bars were found to depend strongly on the growth rate and alloy composition. TiAl alloys with composition of 47 and 50 at.%Al grown under the condition of 10 mm/h showed Ti3Al(α2)/TiAl(γ) layer structures similar to single crystals. As the growth rate increased, the alloys with 47 and 50 at.%Al compositions showed columnar-grain structures. However, the alloys fabricated under the condition of 10 mm/ h had a layered structure, but the alloy with increased growth rate consisted of γ single phase grains. The alloy with a 53 at.%Al composition showed a γ single phase regardless of the growth rate. Room-temperature tensile tests of these alloys revealed that the columnar-grained material consisting of the layered structure showed a tensile ductility of larger than 4 % and relatively high strength. The high strength is caused by stress concentration at the grain boundaries; this enhances the secondary slip or deformation twinning across the layered structure in the vicinity of the grain boundaries, resulting in the appreciable ductility.

The number of North Korean defectors in South Korea has reached 30,000, however, it has been reported that many of them still have adaptation problems. Research on adaptation of North Koreans to South Korean society has been approached mainly from social, economic, and psychological perspectives, and little research has been conducted on their adaptation in terms of lifestyle of North Koreans in South Korean society. Adaptation to daily life pattern in a new social-cultural environment may be examined in the context of acculturation. As a part of the daily life, we are focusing on North Korean defectors’ clothing behavior and how they use clothing as a strategic tool for their adaptation to South Korea. The results of this study may provide marketers the information needed to develop mobile applications to help the North Korean defectors adapt to South Korean fashion style. This research also examined the impact of fashion SNS and word-of-mouth communication as a means of identity formation. In depth interviews using snowball sampling were conducted with 10 North Korean defectors in their 20s and 40s who agreed to voluntarily participate in the research from December 2016 to February 2017. The findings from the interviews are as follows. First, according to Berry’s(1997) types of acculturation, North Korean defectors were classified based on the subjective aspects(e.g. clothing norms) and objective aspects(e.g. clothing purchase behavior) of their daily clothing behavior. The Integrators still tried to abide by the clothing norm acquired in North Korea, but at the same time accepted the clothing norms of South Korea and tried to change their personal ideal. In the objective aspects, their clothing styles still reflect North Korean fashion norms, yet they newly acquire norms regarding thin body ideals or skin care management in the South. They also showed the change of store preference and choices as they become adapted to South Korean culture. The second group, Assimilators show high degree of acceptance of South Korean culture. They regarded the sense of belonging to South Korean society and appearance management as important. Many of them played a role as a fashion adviser among their North Korean peers while they have formed and kept the social network with South Korean. Thirdly, Segregators are the people who try to maintain North Korean culture and try to segregate from the South Korean (host) culture. Defectors in this type still abided by the clothing norms they acquired while in North Korea, and had a negative viewpoint on the South Koreans' styles. They still preferred North Korean fashion style, and were familiar with using North Korean words for expressing terminology related to fashion. Finally, Marginalized group is the people who consider themselves being individual and independent self-standing entity with low degree of acceptance of South and North Korean culture. They sought to express their own individuality before and after defecting by creating their own style. This study may contribute to the understanding of adaptation process, not only of North Korean defectors, but also other immigrants to other countries.

Since 2008 to 2014 the operating margins of Chinese traditional retail industry went a sustained downward. Instead, the operating margins of online-store have been the sudden explosion. In this case which online-store sale the same products with traditional market, my research try to find out how to improve the state of traditional market since 92.5% practitioners of retail industry are doing their business in traditional market. Customer equity can estimate customer lifetime value for the company (Rust et al, 2004). The firm can make proper marketing strategy with customer equity. Customer equity can both satisfy consumers and make a profit for the company (Lemon et al., 2001).So we built a model to connect service quality and customer equity to study how to prove the competitive power of traditional market. In this paper we used customer satisfaction and brand attitude as mediating variables since Store brands have become an important contributor to retail differentiation and basis for building store loyalty (Dodd and Lindley, 2003) and in retail market customer equity varies with customer satisfaction( Pappu and Quester 2006). Considering that Chinese economic growth rate was slowing down, traditional market is being a priority for Chinese Government to relieve severe export pressure and employment pressure. In this research we would like to study the relationships among service quality, customer satisfaction and brand attitude and how they influence customer equity in traditional markets. For this purpose we built a model which composed by service quality, satisfaction brand attitude and customer equity and tested it. The survey was collected from traditional markets in China and South Korea and the data was analyzed by AMOS and SPSS.

Introduction The concentration of manufacturing factories in China signals a significant change in the global economy. Manufacturers in countries that are not price competitive feel a sense of crisis and use servitization in the manufacturing industry as a countermeasure. In particular, with the recent rapid development of IoT and AI, service methods are becoming faster and more diverse resulting in increased research on servitization. Vandermerwe and Rada (1988), who first mentioned the term servitization, define it as providing customer-focused products, services, support, self-service, and knowledge, all bundled together. Despite numerous studies on servitization few consider the customer’s perspective, although many consider the producer’s point of view. So far existing research only explored on how consumers accept value-in-use based on an accurate understanding of consumers' needs from the consumer perspective in servitization, based on expectation-confirmation theory. This study examines how customers accept servitization and links it to customer satisfaction. Literature review Servitization Ren and Gregory (2007) defined servitization as a strategic change in which manufacturing companies develop service-oriented or better services to satisfy customers, gain competitive advantage, and improve corporate performance. Raja et al. (2013) examined servitization to find the most important attributes of value-in-use for customers using servitized products and classified them into seven attributes. This study is based on the seven attributes identified by Raja et al. (2013). Perceived Usefulness, Confirmation, and Customer Satisfaction Bhattacharjee developed the Continuance Use Model based on the expectation-confirmation theory and conducted empirical studies for verification (2001b). Our study analyzes the correlation between customer acceptance process and customer satisfaction based on the Expectation-Confirmation model by Bhattacharjee (2001b). Research method We conducted surveys and analyzed the data of 50 Korean university students and members of the public using Smart Pay (Samsung Pay, Apple Pay etc.). The reliability of the questionnaire was verified by using the Cronbach’s alpha values and exploratory factor analysis. The seven variables of the value-in-use attributes of servitization identified by Raja et al. are as follows: relational dynamic, accessibility, range of product and service offering, knowledge, price, delivery, and locality. We measured three additional variables: perceived usefulness, confirmation, and customer satisfaction. Contributions Academic contribution This study provides a theoretical basis for examining the relationship between variables and the influence of the value-in-use attributes of servitization on customer acceptance and satisfaction. Practical contribution We present implications for customer satisfaction in the servitization process of manufacturing companies by explaining how customers accept the value-in-use attributes of servitization.
