'Instagrammable' is a new term which means a photo or a series of pictures are worth posting on Instagram. Since Instagram is an image-oriented social media platform, it is important to give users proper awareness through images in order to be an instagrammable post. In this study, we explored the proper delivery method of messages within instagrammable posts through the use of hashtags(#). Specifically, we paid attention to the use of 'Card News', which involves a series of images that form a short narrative. Hashtags play an important role that they often describe sharing intention of the post, and we found analyzing the use of hashtags in Card News posts is a good indicator of users' Instagram activities. Currently, there are more than 580k posts are found with the search keyword Card News, and the number is increasing. In this study, we collected and analyzed more than 50k hashtags on Instagram to explore how news stories are posted from both the general users and news media accounts. Furthermore, we conducted interviews with journalists to analyze how news media are making use of Instagram as a legitimate place to share news stories with impact.

Market share is one of the most important measures in the valuation of prospering firm. It plays a role of composite indicator for the competitiveness of firm. So, the understanding of the underlying process of market share is inevitable factor for the econometricians and the business engager. Lately, the Korean Economy has been placed in the control of IMF. This shock will cause a lot of influence over the domestic economy. The idea that the information about the past shock-response experience will do us good for dealing with this kind of economic shocks is not new. Among numerous markets, we pay attention to the durable goods market, especially automobile market. The automobile market has large repercussion effect over the domestic economy on the issue of both national employment and technology integration. We divided the Korean automobile market into three segments: small, medium, and large-sized car, while each proportion of these segments has been changing slowly. We propose a Bayesian approach to detect and forecast structural changes in time series of the market shares in the domestic automobile market, especially for level shifts and drift changes, and compare the empirical results with other existing approaches.

The servicescape of a hotel means the physical environment in which a service is produced and consumed. The users perceive the quality of the service and their inner response affects their satisfaction or behavior such as repurchase. Servicescape has been addressed mainly in marketing as a strategic element of service marketing research. The aim of this research is to find out which dimensions of servicescape is required in hotel facilities and to identify servicescape of tourist hotel in Seoul. For this study, questionnaire survey with facilities users and site research were used. Servicescape factors were derived cleanliness, convenience, aesthetics and ambience. According to case study, the most significant servicescape need for hotel facilities was cleanliness. Therefore, facility managers must continuously manage the facilities. In terms of convenience, layout of guest bathrooms and furniture was the important indicator of servicescape. Facility aesthetics play an important role as differentiation from competitors. By providing a customized design, customers choose hotels that best satisfy their needs. It is important to recognize that ambience can be controlled to a large extent by facility management.

As the usage of smart phones continues to increase, the control UI, which users have to continue to use, sometimes finds a heavy burden on users. Therefore, in this study, we have studied the control user interface structure along with the theoretical background of the control user interface, and we have studied the role and usage of the control component based on it. Typical commonly used controls are button controls for transmission, selection controls for various selections, link controls for navigation, text controls for inputting characters, indicator controls for feedback on progress, A message control that displays information about warnings and errors, and a window control such as a dialog box. The structure of the control should be designed according to the use of the separated control to help the user efficiently use the control user interface. Based on the analysis of the theoretical usage of representative components belonging to the separated controls, we presented a new and correct way to use the control to improve the user experience. The use of improved control components will help to design the control structure efficiently and to improve the user experience.

P300 is widely used as a neurophysiological indicator of cognitive processing, which is known as reflecting controlled processing. MMN (mismatch negativity), early response prior to P300, is known as reflecting an early stage of information processing and having involuntary attention and automatic awakening or sensory memory. This study for normal people shows that electric potential of P300 and MMN are in close correlation (r=-0.673, p<0.05). That is, it is observed that the higher negative value electric potential of MMN measured at cerebral forehead-center has, the higher value electric potential of P300 measured at cerebral center-vertex has. This fact implies that working memory for temporary storage and operation of stimuli, and involuntary attention which constitute automatic information processing, an early stage of information processing, play a crucial role in efficient information processing. On the other hand, considering that MMN of cerebral forehead-center and P300 of cerebral center-vertex are in close correlation, it is necessary to pursue further study of cerebral parts which generate P300 and MMN in information processing.

With the development of cognitive science and environmental psychology, there have been growing researches and discussions on the relationship between the residential design preferences and personality types. MBTI personality types have been earning popular credibility. MBTI means Myers-Briggs Type Indicator. It is based on Carl Jung's theory of psychological type. This study is based on Myers-Briggs theory to explain residential furnishing preference and explores the relationship between the four bi-polar personality types-Extroversion/Introversion, Sensing/Intuition, Thinking/Perceiving and residential furnishing preference. These tests were conducted to two hundred and twelve adult residents who live in Seoul, Korea. These tests were analyzed several significances by Chi-Square with SPSS for windows software. (E) Extroverted residents prefer layouts for interaction with guests. (I) Introverted residents prefer centripetal layout around the bed. (S) Sensing residents prefer practical and functional layouts. (N) Intuitive residents prefer personal and conceiving layouts. (T) Thinking residents prefer for attribute of space. (F) Feeling residents for familiar conversation. (J) Judging residents prefer systematic and complete layouts. (P) Perceiving residents prefer adaptable and flexible layouts. In conclusion, personality types can have a determining role in preference of residential furnishing layouts. This study suggests that residential designers should take into account clients' personality types prefer effective designing and should provide a variety of alternatives reflecting clients' preferences. This will promote clients' pleasantness and satisfaction in dwelling at home.

A steel shear wall with double-tapered links and in-plane reference was developed for assisting the assessment of the structural condition of a building after an earthquake while maintaining the original role of the wall as a passive damper device. The double-tapered link subjected to in-plane shear deformation is designed to deform torsionally after the onset of local buckling and works as an indicator of the maximum shear deformation sustained by the shear wall during an earthquake. This paper first examines the effectiveness of double-tapered links in the assessment of the structural condition under various types of loading. A design procedure using a baseline incremental two-cycle loading protocol is verified numerically and experimentally. Meanwhile, in-plane reference links are introduced to double-tapered links and greatly enhance objectivity in the inspection of notable torsional deformation with the naked eye. Finally, a double-layer system, which consists of a layer with double-tapered links and a layer with rectangular links made of low-yield-point steel, is tested to demonstrate the feasibility of realizing both structural condition assessment and enhanced energy dissipation.

Crack opening governs many transfer properties that play a pivotal role in durability analyses. Instead of trying to combine continuum and discrete models in computational analyses, it would be attractive to derive from the continuum approach an estimate of crack opening, without considering the explicit description of a discontinuous displacement field in the computational model. This is the prime objective of this contribution. The derivation is based on the comparison between two continuous variables: the distribution if the effective non local strain that controls damage and an analytical distribution of the effective non local variable that derives from a strong discontinuity analysis. Close to complete failure, these distributions should be very close to each other. Their comparison provides two quantities: the displacement jump across the crack [U] and the distance between the two profiles. This distance is an error indicator defining how close the damage distribution is from that corresponding to a crack surrounded by a fracture process zone. It may subsequently serve in continuous/discrete models in order to define the threshold below which the continuum approach is close enough to the discrete one in order to switch descriptions. The estimation of the crack opening is illustrated on a one-dimensional example and the error between the profiles issued from discontinuous and FE analyses is found to be of a few percents close to complete failure.

Purpose- This study seeks to investigate the impact of foreign remittances on private sector investment and the moderating role of banking sector development in Sub-Saharan African Countries. Research design, data, and methodology-The study has used a sample of 15 Sub-Saharan African countries and data for the years 1986 - 2017. Data was obtained from the World Bank Development Indicator (WDI) Database. Panel data diagnostic tests were conducted to ascertain the suitability of the data for regression analysis. The data was analyzed through descriptive and inferential statistics, while the hypothesis was tested through hierarchical regression analysis. Results- The finding of this study indicates that foreign remittances and banking sector development had a significant and positive effect on private investment in Sub-Saharan Africa. Besides, the banking sector development significantly moderated the foreign remittances and private sector investment relationship. Conclusions- Based on the results, the study concludes that banking sector development has an important influence on foreign remittances and private sector investment nexus. Due to the antagonistic interaction between foreign remittance and banking sector development, the study recommends the use of alternative ways of channeling remittances to private investment such as; issuance of diaspora bonds and appeal for direct investment by citizens living abroad.
