In recent years, IT advancement has brought out the new Internet communication environment such as online social network services, where people are connected in global network without temporal and spatial limitation. The popular use of online social network helps people share their experience and preference for specific products and services, thus holding large potential to significantly affect firms' business performance through Word-of-Mouth (WOM). This study examines the role of online social network in raising WOM effect on the movie industry by comparing with the similar role of Internet portal, another major online communication channel. Analyzing 109 movies and data from both Twitter and Naver movie, we found that significant WOM effect exists simultaneously in both Twitter and Naver movie. However, we also found that different figures of online viral effects exist depending on the popularity of movies. In the hit movie group, before the movie release, the WOM effect occurs only in Twitter while the WOM effect arises in both Twitter and Naver movie at the same time after the movie release. In the less-popular (or niche) movie group, the WOM effect occurs in both Twitter and Naver movie only before the movie release. Our findings not only deepen theoretical insights into different roles of the two online communication channels in provoking the WOM effect on entertainment products but also provide practitioners with incentive to utilize SNS as strategic marketing platform to enhance their brand reputations.

This research explores the relationship between gender equity within family and second birth in Korea. For a factor analysis on the intention of having additional children for women with one child, I have used the data from the 2005 National Survey on Marriage and Fertility Trend" of the Korea Institute for Health and Social Affairs. Among 516 samples(year of 20-44), women planning to have second birth are 54.7%, and others have answered that they have no intention to have second birth. As a result, main causes affecting progressing to second birth seemed to be family planning on family cycle, such as controlling age gaps between first and second child, composing children genders as they wish etc. The variable of "gender equity between couples" in progressing to second birth are of significant only with married working women group. In case of married working women, more the husband's houseworking hours increase, the more prone to progress to second birth. However, in case of housewives, gender equity level, such as husband's housework hours or share of housework are not of significant influence in progressing to second birth. Not only working mothers but also housewives need the realization of gender equity within the family and the expansion of social support system for work-family life balance.

This study explores Korean youths' gender equality consciousness in an attempt to search for a way to increase youth's gender equality consciousness. First, this study carries out a survey of youths' gender equality consciousness based on questionnaires collected from a nationwide sample. Second, this study attempts to identify key points needed to evaluate youths' gender equality consciousness in terms of youths' general values. The data used for this survey is from the survey on youths' values conducted by Korean Institute for Health and Social Affairs in 2006 with a sample of 11,240 students from 132 schools nationwide. As a result, youths in 2006 had higher gender equality consciousness than that of previous years(2002). Especially, the support for the fair share of domestic work in the house by youths was significantly increased than the past. However, the survey of youths' values showed clear gender gaps in general attitudes of youths including gender equality consciousness. Female students not only had higher gender equality consciousness than male students but also had higher levels of 'universal value' which would allow one to become sensitive to discrimination and 'self development and achievement value'. In contrast, male students scored high on 'power-oriented value' related to discriminatory attitudes. Therefore, the study recommends focusing on alleviating the gender gaps through school education and other various media education.

Using a generalized translog multiproduct cost function model, this paper examines economies of scale and scope in the vertically-integrated Korean railway industry. The paper then conceptualizes that the Korea National Railroad (KNR) produces four outputs (passenger-kilometers, ton-kilometers of freight, average length of passenger trips, and average length of freight haul) using three input factors(labor, fuel and maintenance, and rolling stock and capital). Using time series data collected from the KNR's annual records for the years from 1977 to 2002, the simultaneous equation system consisting of a cost function and two input share equatins is estimated with the Zellner's iterative seemingly unrelated regression. The findings show that the cost function corresponding to a non-Cobb-Douglas, non-homothetic, and non-homogeneous production technology adequately represents the KNR's cost structure. On the other hand, the Korean railway industry experiences sizeable overall scale economies, which result from substantial product-specific scale economies associated with passenger-kilometers and freight ton-kilometers and from scope economies associated with their joint production. In addition, the magnitude of economies of scope is influenced largely by the ratio of passenger trips, and has increased over time as the former has increased while the latter has decreased.

In recent years, the use of BIM in domestic construction has been increasing, but it is used mainly for internal and external visualization rather than for BIM design including drawings. For this reason, several studies have highlighted the lack of libraries and economic problems for BIM design. In other words, for the most economically small domestic design offices, activating the BIM design is a negative factor because it is difficult to invest the necessary manpower and cost to produce and use the required BIM library. The BIM design can be more applicable if the library can be supplied economically, easily, and quickly. In this study, BIM library business model and consideration factors that can provide BIM library service economically, easily, and quickly by considering the existing building material selection task and BIM library are presented. The proposed business model will increase the number of suppliers of BIM libraries, which are lacking in Korea, and will enable an effective BIM design at low cost and effort. If a service that reflects the business model proposed in this study is made, an integrated database that can consistently share information in the design, construction, and maintenance stages will be constructed. This can monitor the changes in material and equipment information during the life cycle of the building. The database can be used to monitor any changes in material and equipment information throughout the life cycle of a building, so that it can be used as historical data for effective design and maintenance as well as for material and equipment upgrades.

Purpose - Recently, many theoretical researches suggested that arts-based marketing strategies provide many benefits for marketers to differentiate their brand or product from others. However, there has been little research focusing on consumers' response types from artwork (artifact-emotion appraisal; A-emotion vs. represented world-emotion appraisal; R-emotion). In order to deepen our understanding of arts-based marketing strategies, we addressed a research question related to how artwork-provoked consumers' emotional response can impact the perceived evaluation of art infused products. Research design, data, and methodology - To answer the research question, we conducted a pretest and one experimental study. The experimental study was 2(art-provoked response type: A-emotion vs. R-emotion) by 2(emotional valence: positive vs. negative) by 2(produce type: hedonic vs. utilitarian) mixed design. The art-provoked response type and emotional valence were between-subject design and product type was within subject design. For the experimental study, 108 undergraduate students and graduate students were randomly assigned to one of 4 conditions (A-emotion-positive, A-emotion-negative, R-emotion-positive, R-emotion-negative). Participants reported their evaluation of art-infused product and other items for a manipulation check. Results - The major results from the experimental study are as follow. First, participant's art-provoked response type influenced evaluation of art infused products differently. More specifically, the effect of emotional valence of artwork on product evaluation was not significant in A-emotion. However, in R-emotion, relative to the product with artwork provoked negative emotional valence, the product with artwork provoked positive emotional valence elicited significantly higher product evaluation. Second, product type also affected the art infusion effect significantly. Particularly, the differential effect of participant's art-provoked response type on product evaluation revealed when it is for a utilitarian product, but not for a hedonic product. Conclusions - Theoretically, the findings of this study expand academic research on art infusion. And the findings also can be extrapolated to generate lots of implication for marketers. In sum, when they plan art marketing strategies to build the favorable relationship with their customers, they need to consider customers' response type of an infused art and product type.

This study delineates how recipients access, understand, and make use of social welfare information in their life-worlds. Through this vivid illustration about recipients' information behaviors, this research aims to suggest that government-centred welfare informatization policy should be readjusted. South Korean government has made enormous efforts to deliver and share social welfare information and knowledge with recipients, by organizing IT eduction programmes, offering free computers, and opening welfare portals. However, despite of such endeavors, not a few recipients find difficulty in gaining, grasping, and using welfare information. In fact, welfare informatization programmes have so far been initiated by the governmental bureaucratic system, and the voice of recipients have hardly been reflected on the informatization policy. Starting from this problem, this study examines how low-income recipients perceive and accept social welfare information in their daily lives and reflects on social welfare information at their point. For this purpose, this research conducted in-depth interviews with 14 recipients and analyzed the data using a framework analysis method. Based on the results, it raises the need for the remodelling of current welfare informatization measures from the perspective of recipients rather than following the custom of the bureaucratic system.

As the intelligent revolution triggered by digital technology, unmanned vehicles such as self-driving cars, robots, and drones appeared, which brought about innovative changes in the industry. Gyeonggi Local government has established both an ordinance and a basic plan regarding unmanned vehicles. It is time to prepare a data-based policy by understanding the current state of the unmanned vehicle industry in the province. As a result of the survey, the unmanned vehicle industry in Gyeonggi Province is 25% of the nationwide, and more than 88% is concentrated in the southern part of Gyeonggi Province. The land sector such as the robot and autonomous vehicles are focused on 71.4% and the aviation sector such as drones are 26.7%. However, unmanned vehicle companies in Gyeonggi-do are mostly small-sized businesses with less than 10 years of experience and are in the stage of introduction and growth level. They have a plan to improve technology through continuous R&D by hiring human resources. Therefore, Gyeonggi-do needs to consider policy support for sustainable growth of start-up and small enterprises and for fostering professional manpower and technical skills as well as for establishing an unmanned vehicle industry network to create, share, and spread knowledge.

This study was conducted to understand and describe Korean nurses' perception of person-centered care for elderly patients in long-term care hospitals. Qualitative data were collected through four focus group interviews consisting of 21 nurses working in four long-term care hospitals in Jeolla and Gyeongsang provinces. Participants completed interviews from July 19 to 30, 2018. All interviews were recorded, transcribed, and analyzed by employing the thematic analysis method. Six main themes for the attributes of person-centered care for elderly patients in the long-term care hospitals were conceptualized: respecting individual needs, walking to the end, supporting hidden dreams, becoming a family partner, helping patients live like they are at home, and changing culture. Person-centered care perceived by nurses was conducted to provide individualized nursing according to elderly's preferences and help them discover the value and meaning of life through various activity programs. Nurses also recognized person-centered care to maintain cooperative relationships with their family members and share their decision-making process, as well as to form a physical environment and organizational culture that respects the rights and autonomy of the elderly. Based on the results of this study, it is necessary to identify the diverse needs of the elderly and develop nursing intervention programs based on person-centered care.

The purpose of this research was to introduce a network analysis method for analyzing technology trends in the aerospace industry at the Farnborough International Airshow (FIA), one of the world's three major airshows. Civil and defense companies and government and military officials from 112 countries and 1,500 agencies convened at FIA 2018 to share and explore recent trends in the aerospace industry. We studied aerospace technologies from 45 countries, 1,108 exhibiters, and 223 technology categories via centrality analysis. The results from the network analysis showed that machining is the center of aerospace technology. However, there were quite different tendencies, depending on the region and country. The centers of aerospace technology are machining in Europe and the United Kingdom, aircraft components in Asia, and engine components/controls in the United States. In Korea, no one key technology was recognized, due to the country's small attendance. We hope this research will be conducive to aerospace technology-and-research planning, and that it will be an appropriate tool to help domestic manufacturers boost their exports.
