Purpose – As the scope of existing digital transformation expanded to various degrees, the Fourth Industrial Revolution came into being. In 2016, Klaus Schwab, Chairman of the World Economic Forum (WEF), said that the new technologies that lead the fourth industrial revolution are AI, Block chain, IoT, Big Data, Augmented Reality, and Virtual Reality. This technology is expected to be a full-fledged fusion of digital, biological and physical boundaries. Everything in the world is connected to the online network, and the trend of 'block chain' technology is getting attention because it is a core technology for realizing a super connective society. If the block chain is commercialized at the World Knowledge Forum (WKF), it will be a platform that can be applied to the entire industry. The block chain is rapidly evolving around the financial sector, and the impact of block chains on logistics, medical services, and public services has increased beyond the financial sector. Research design, data, and methodology – Figure analysis of data and social science analytical software of IBM SPSS AMOS 23.0 and IBM Statistics 23.0 were used for all the data researched. Data were collected from hotel employees in China from 25th March to 10th May. Results – The purpose of this study is to investigate the effect of the block chain characteristics of the existing hotel reservation system on the intention to use and to examine the influence of the block chain characteristics of the hotel reservation system on the intention to use, We rearranged the variables having the same or similar meaning and analyzed the effect of these factors on the intention to use the block chain characteristic of the hotel reservation system. 339 questionnaires were used for analysis. Conclusions – There are only sample hotel workers in this study, and their ages are in their 20s and 30s. In future studies, samples should be constructed in various layers and studied. In this study, the block chain characteristics are set as five variables as security, reliability, economical efficiency, availability, and diversity. Among them, Security and reliability made positive effects on the perceived usefulness. Also, security and economics did on the perceived ease. Availability and diversity did on both perceived usefulness and perceived ease. Perceived ease did on perceived usefulness. And perceived ease and perceived usefulness did on user intent. But security and economics did not on the perceived usefulness

Purpose - Unlike in the past, individualistic thought is more dominant than groupism where members prioritize organizations. Such changes run counter to the direction of the survival of the companies, which calls for companies to explore strategies to address thems. As one of the solutions, many people highlights social capital. However, since most studies have been conducted on the definition and characteristics of social capital, there is not enough prior factor research on the formation of social capital. So the current situation require researches on the formation of social capital. Research design, data, and methodology - To achieve the purpose, the literature and the empirical studies were combined. Deriving workplace democracy and servant leadership as factors affecting the formation of social capital through the literature, and this factors have modeled assumptions about the impact on social capital, and have established hypotheses to verify them. The survey which is conducted to verify the hypothesis and questionnaires are derived base on the variables used in the previous studies. The survey was conducted 447 respondents in Korea. Results - As a result, we found that the workplace democracy is positively functioning with the formation of social capital. It means that the democracy functions as a universal element to enhance the quality of social capital at the workplace. The evidence also shows that the positive impacts of the servant leadership on the formation of social capital. And the survey shows that groups with high level servant leadership had a higher impact on the formation of social capital than those with low levels leadership. Conclusions – At present, the social capital has become an important factor for the companies pursuing high performance workplaces. We found that the workplace democracy and the servant leadership affect the formation of social capital. It means that to increase the employees’ sense of community and solidarity, it is need to form democratic environment with the servant leadership. Therefore, based on the results of this study, the workplace democracy and the servant leadership can present strategic implications that can increase the social capital.

Purpose – The purpose of this paper is to find out a range of cues that trigger employees to willingly make efforts for corporate development in small and medium enterprises. This was determined by assessing the effects of employees' value inclination on their job satisfaction and organizational citizenship behavior as well as how they perceived their organizational support. Research design, data, and methodology – A total of 126 valid questionnaire sheets collected from SME employees were analyzed with SPSS 24.0 and AMOS 24.0 involving simple regression analysis, multiple regression analysis, hierarchical moderated regression analysis and 3-step mediated regression analysis. Results – The analyses highlighted employees’ personal value inclination had positive effects on their job satisfaction, which in turn enhanced their organizational citizenship behavior. Meanwhile, individualist and collectivist inclination exerted greater effects on job satisfaction and organizational citizenship behavior, respectively. The study also revealed that perceived organizational support moderated the relationship between job satisfaction and organizational citizenship behavior. Conclusion – Hence, CEOs in SMEs should avert any dichotomous analysis of their employees’ value inclination, respect their personal value inclinations and also apply factors that could raise their job satisfaction. Likewise, it was shown that SME employees need to make personal efforts for organizational development.

탄소섬유는 경량이면서 높은 기계적 특성 때문에 우주항공, 선박, 자동차, 토목 및 건축과 같은 산업분야에서 그 어느 때 보다 더 광범위하게 적용되고 있다. 본 연구는 섬유혼입률 및 섬유길이 변화에 따른 탄소섬유 보강시멘트 복합재료( CFRC)의 역학적 특성과 휨 거동을 분석하였으며, 또한 자연 낙하시험에 의한 모르타르 시편에 대한 내충격성을 비교, 검토하였다. 더불어, 탄소섬유(CF)의 혼입률은 0.5%, 1.0%, 2.0% 및 3.0%로 변화를 주었으며, 각각의 섬유길이는 6 mm와 12 mm를 사용 하였다. 실험결과, 플로우 값은 탄소섬유의 뭉침현상으로 인해 유동성 측면에서 매우 불리하였으며, 단위용적질량은 다소 감소하였다. 특히, 압축강도는 탄소섬유 혼입량이 증가함에 따라 감소하는 것으로 나타내었다. 반면 휨 강도는 섬유 길이가 12 mm이고 2% 혼입한 것이 가장 높은 휨 강도를 보였다. 내충격성 시험결과, 보통 모르타르 시편은 완전파괴까지의 낙하횟수가 2∼3회 정도 걸리지만 반면 CFRC 시편은 섬유혼입량이 증가함에 따라 다소 차이가 있지만, 섬유길이가 12 mm이고 섬유혼입량 2% 인 경우 충격에 대한 저항성이 가장 높았다.

Purpose – Prior studies reported that the opacity of information caused stock price crash. If managers fail to disclose unfavorable information about the firm over a long period of time, the stock price is overvalued compared to its original value. If the accumulated information reaches a critical point and spreads quickly to the market, the stock price plunges. Information management by management's disclosure policy can cause information uncertainty, which will lead to a plunge in stock prices in the future. Thus, this study aims at examining the impact of disclosure quality on crash risk by focusing on the unfaithful disclosure firms. Research design, data, and methodology – This study covers firms listed on KOSPI and KOSDAQ from 2004 to 2013. Firms excluded from the sample are non-December firms, capital-eroding firms, and financial firms. The financial data used in the research was extracted from the KIS-Value and TS2000 database. Unfaithful disclosure firm designation data was collected from the Korea Exchange’s electronic disclosure system (kind.krx.co.kr). Stock crash is measured as a dummy variable that equals one if a firm experiences at least one crash week over the fiscal year, and zero otherwise. Results – Empirical results as to the relation between unfaithful disclosure corporation designation and stock price crashes are as follows: There was a significant positive association between unfaithful disclosure corporation designation and stock price crash. This result supports the hypothesis that firms that have previously exhibited unfaithful disclosure behavior are more likely to suffer stock price plunges due to information asymmetry. Second, stock price crashes due to unfaithful disclosures are more likely to occur in Chaebol firms. Conclusions – While previous studies used estimates as a proxy for information opacity, this study used an objective measure such as unfaithful disclosure corporation designation. The designation by Korea Exchange is an objective evidence that the firm attempted to conceal and distort information in the previous year. The results of this study suggest that capital market investors need to investigate firms' disclosure behaviors.

The purpose of this study is to examine the effect of climatic elements on the arabica coffee yield during the various growth stages of coffee plant for the period of 1996-2017 over Costa Rica. For the future scenario, change rate of arabica coffee yield is also estimated using the data of production and cultivated area. The cultivation area and the yield of arabica coffee has been decreasing since the 1990s in Costa Rica. The decreasing trend in arabica coffee yield could have a negative effect on Costa Rica’s coffee industry in the future. During the dry season, the yield of arabica coffee has significant negative correlation with precipitation at the stage of flowering in the month of February. In case of wet season, coffee yield and temperature were negatively correlated while precipitation showed positive association with coffee yield at the stage of growing period in the month of August. However, the observation revealed the excessive precipitation drastically reduced arabica coffee yield in 2013 during August, the month of wet season. According to the RCP 4.5 and RCP 8.5 climate change scenarios, due to high temperature and fluctuated precipitation the yield of arabica coffee is unstable and the future of coffee industries is also insecure.

The study aims to investigate the nexus of between role identity, self-efficacy, feeling of energy, and employee creativity in the hotel industry of Korea. The employees’ innovative behaviors like creativity have been many researchers’ interest for decades in the hotel industry. The hypotheses depicting the relationship among the variables have been proposed based on a review of existing literature. The number of 215 cases was used for final analysis and the results were explained through structural equation modeling. The results indicate the hotel employees’ role identity and creative self-efficacy positively influenced their feeling of energy. Further, both role identity and creative selfefficacy make significant impact on employee creativity. Feeling of energy also makes a positively significant impact on employee creativity. Feeling of energy partially mediates the relationship between the two independent variables and employee creativity. As a result, creative role identity, self-efficacy, and feeling of energy explain the variance of the hotel employees’ creativity. The results present that hotel practitioners need to regard their employees’ creative roles and build organizational culture to support creative activities so as to enhance employee creativity. Finally, theoretical and practical implications for the hotel industry and future studies have been discussed.

China has become the second largest economy since 2010. China’s economy is supported by the rapid growth of its automobile industry. The rapid growth of the automobile and tire industry will increase the natural rubber (NR) demand as its primary raw materials. Although as a significant producer, China cannot fulfill the consumption by its domestic production. Thus China relies heavily on import from Southeast Asia countries as the primary producers of natural rubber in the world. China and Southeast Asia are dependent on their economy in terms of the availability of natural rubber as raw materials. But the economic slowdown in China since 2008 is expected to affect the international trading between China and Southeast Asia countries. This research aims to analyze the determinants of NR export from Southeast Asia to China using panel data analysis. The results show NR price, exchange rate, and China’s economic slowdown significantly affect NR export to China, while Southeast Asian NR production has no significant effect. China as the main importer of NR from Southeast Asia has a big role in growing NR export in Southeast Asia. If China's economy doesn’t improve soon, it will affect the economy in Southeast Asia.

The objective of this study was to establish whether global macroeconomic indicators affect the profitability of Korean shipping companies by using panel regression analysis. OROA (operating return on assets) and ROA (ratio of net profit to assets) were selected as proxy variables for profitability. OROA and ROA were used as dependent variables. The world GDP growth rate, interest rate, exchange rate, stock index, bunker price, freight, demand and supply of the world shipping market were set as independent variables. The size of the firm was added to the control variable. For small-sized firms, OROA was not affect by macroeconomic indicators. However, ROA was affected by variables such as interest rates, bunker prices, and size of firms. For medium-sized firms, OROA was affected by demand, supply, GDP, freight, and asset variables. However, macroeconomic indicators did not affect ROA. For large-sized firms, freight, GDP, and stock index (SCI; Shanghai Composite Index) have an effect on OROA. ROA was analyzed to be influenced by bunker price and SCI.

Purpose – This research explores the impacts of third-party logistics (3PLs) within the aircraft Maintenance, Repair and Overhaul (MRO) industry in the United Arab Emirates (UAE) to explore the role of collaborative relationships for improving outsourcing. Globalization and time based competition have changed business environments and challenged the conventional management strategies that are related to core competencies and operational models. Organizations are forced to devise innovative practices in which logistics outsourcing to 3PLs offers significant advantages. Research design, data, and methodology – This case study was conducted within a leading global aircraft MRO organization whose reach spans across Europe, the Middle East, Asia and the Americas. The methods used face to face semi-structured interviews, validated through further focus group discussions. Results – These findings highlight the effectiveness of collaborative relationships on their role to improve outsourcing and also demonstrated that MROs gain several advantages from 3PL arrangements. However, any gaps in outsourcing management elevates potential risks to organizations as well, which could result in reputational, operational and financial losses. Conclusions – Although generalizability is not possible due to the case study approach, generality suggests that in order to reduce reputational, operational and financial risks, enhanced collaboration with 3PLs is recommended to optimize outsourcing arrangements.

모더니즘과 포스트모더니즘 양식의 영향 아래 많은 예술 작품들이 무용 안에서 다양한 예술 매체의 통합을 추구하기 시작했고, 새로운 현대무용 작품들을 만들기 시작했다. 이 연구는 많은 무용가들의 작품을 분석하여 현대무용의 멀티미디어 통합에 대한 연구에 초점을 맞추었다. 보다 구체적으로는 베이징무용쌍주(北京舞蹈双周)의 현대무용 작품들에 대한 조사를 통해 현대무용에서 미디어의 적용과 특성을 알아내는 것을 목표로 하였다. 연구결과 현대무용이 ‘반무용’ 경향의 개념을 일반화하여 미디어의 다원적 표현을 추구한다는 것을 발견하였다.

본 논문은 윤치호가 1885년부터 1888년까지 중국 상해에 머물며 남감리회 미션스쿨인 중서서원에서 수학하던 시기를 그 연구대상으로 삼아, 윤치호가 중서서원에서 받은 근대교육과 종교교육에 대해 살펴보면서, 미션스쿨이 윤치호의 개종에 미친 영향에 대해 고찰해 보는 것을 목표로 하였다. 이에 대해 본 논문은 첫째, 윤치호가 상해에서 수강한 과목들을 당시 중서 서원의 8년 학제에 포함된 교과목들과 비교하면서 윤치호가 그 중 3-6학년 도 과정을 수학한 것을 밝혔으며, 둘째, 중서서원의 종교교육을 검토하면서 중서서원은 세속학교가 아닌 전형적인 미션스쿨로서, 윤치호도 그가 받은 모든 수업에서 성경이 교재로 사용되었고 매일 두 차례씩 종교예식을 갖고 토요일에는 성경강독 수업을 받았음을 살펴보았다. 셋째, 선행연구에서와 달리 윤치호가 처음 예배당에 간 것은 1885년 2월 15일이 아닌 2월 8일이었으며 교회에 데려간 사람은 알렌이 아닌 로얄 선교사였음을 밝혔고, 이를 통해 윤치호가 중서서원에 입학한 직후부터 선교사들의 특별한 선교적 관심을 받았을 가능성이 컸음을 추론하였다. 결국, 윤치호는 윤리적 종교에 대한 개인적 관심 및 근대 사상에 대한 관심에서 스스로 기독교 에 접근하기에 앞서, 이미 미션스쿨의 종교적 학풍과 선교사들의 전략적 전도 과정을 통해 이미 기독교적 환경에 놓이게 되었던 것이었다.

Purpose - The purpose of this study is to empirically investigate the effect of choice of cause on the purchase intention by dividing it into the situation selected by the consumer and the company. This study also examines the moderating effect of cause options diversity and company-cause fit on the relationship between choice of cause and purchase intention. This will provide the theoretical information necessary to gain an in-depth understanding of the consumer's intention to purchase the cause-related marketing campaign, and in practice, it is expected that companies will be able to obtain useful information for effective planning and execution of the cause-related marketing campaign. Research design, date, and methodology - This study's survey was carried out on the college students of university located in Shandong, China. It was from November 4-11, 2018, and a total of 440 questionnaires were distributed, with 424 collected. Of them, effective questionnaires used in the final study were a total of 400 except 24 that couldn't be used. In this study, empirical analysis was done with frequency analysis, reliability analysis, analysis of variance and simple effect analysis by using Statistics Package SPSS 20.0. Results - The results are reported below: first of all, in the cause-related campaign consumers are more willing to buy the products when they are allowed to choice the focal cause of charity than when the company selects the cause of charity. Furthermore, the positive effect of allowing consumers to choice the cause of charity (vs. company choice) on purchase intentions is greater for high cause diversity to select. Finally, the positive effect of allowing consumers to choice the cause of charity (vs. company choice) on purchase intentions is greater when perceived fit between the company and the cause charity is low. Conclusions - This study extends the scope of the consumer perspective from consumer purchase intention research to the choice of cause in the cause-related marketing. When consumers select the cause, it would be better to provide the cause charity in diversifying selection and provide options for low fit between company and cause charity.

본 논문에서는 노후된 중소규모 RC슬래브 교량에 대한 응답계수를 분석하였다. 이 응답계수는 진동수 기반 교량의 내하력 예측 모델에서 중요한 변수이며, 정적 및 동적 응답계수로 구성되어 있다. 정적 및 동적 응답계수는 교량의 현재와 이전(또는 설계) 상태의 진동수 변화와 충격 계수 변화에 따라 각각 결정된다. 여기서 충격계수 변화는 충격계수 응답스펙트럼에서 교량의 고유진동수에 따라 산출된다. 본 연구에서 고려한 총 4개의 대상교량은 지간길이가 12 m이고 시공 후 30년 이상 된 RC슬래브 노후 교량이다. 진동수 분석을 위해 덤프 트럭을 이용한 현장 동적 재하시험과 설계기반 FE모델을 이용한 고유치 해석을 통해 교량의 현재 및 설계 상태의 고유 진동수를 각각 도출하였다. 충격계수 응답스펙트럼 개발에 있어서 좀 더 현실적인 조건을 반영하기 위해 3축이동하중과 단순지지 및 양단고정 조건을 고려하였다. 분석 결과 응답계수는 0.21에서 0.91까지 광범위하게 분포하였고, 정적 응답계수가 총 응답계수 결과에 크게 기여한 반면 동적 응답계수는 결과에 작은 영향을 미쳤다. 1축 이동하중과 단순지지 조건에서의 응답계수와 비교해 보았을 때 최대 오차는 약 3%미만으로 매우 작게 나타났다.

Many studies have shown that job performance and leadership are important in our society. In addition, to improve the quality of work or to improve the work efficiency is still a lot of challenges for each leader. In Vietnam, there are few specific studies on the impact of leadership styles on employee engagement such as: transformational leadership styles, business leadership styles and leadership styles. In the field of higher education, the fewer studies on these issues. A study is conducted to test the impact of leadership styles on the engagement of cadres, lecturers and staff at public universities in Vietnam. Using adjustment techniques, inspecting the scales and theoretical models representing the relationship among the influential factors. The research is based on a sample of 309 cadres, lecturers and staff currently working in universities in Vietnam and used Structural Equation Modeling (SEM) to test the relationships among the variables. The study results show that the scales of the variables: transformational leadership, transactional leadership, laissez faire leadership, job satisfaction and organizational engagement attain the validity and reliability in the research. The study results also show transformational leadership, transactional leadership and laissez faire leadership are directly and indirectly affected by job satisfaction and organizational commitment.

The study aims to identify Service Quality factors that affect purchase decision on Click and Collect service through the mediating variable of customer emotions at Mobile World stores in Ho Chi Minh City. This study employs a mixed methods research design. Data were collected through online self-completion questionnaire distributed to 316 customers who used to experience Click and Collect service at the Mobile World stores in Ho Chi Minh City, Vietnam. The theoretical model was tested through two-stage regression analysis (PATH model). The findings show that factors of service quality such as Reliability, Responsiveness, Assurance, Empathy, Tangibility, and Emotions affect the decision to purchase online and receive products directly at Mobile World stores in Ho Chi Minh City. Responsiveness and Assurance have a significant positive impact on the customer's emotions. Consequently, these factors should be considered and addressed when conducting multi-channel services. Obviously, employees must first be trained to be able to deliver the promise of the retailer to their customers. Based on the results of the study, the authors provide managerial implications for retailers in Vietnam in the multi-channel retail environment to develop Click and Collect at retail stores across the country and the world.

Service quality has been a point of discussion from the decades as it is important for customer satisfaction, loyalty and retention. Various models have been proposed to measure the quality in the service sector. Models are modified in accordance with context and geography to assess the quality of service better. This study aims to investigate the impact of the modified e-SERVQUAL model on the customer perception about the existing relation and potential scope of doing business with a bank which in-turn will decide the performance of the bank. Statistical data was analyzed through various tests like reliability analysis, correlation and regression analysis using SPSS 25.0. The primary data of e-SQ and performance was gathered from 721 internet banking users using 32 item questionnaire, representing 72% response rates, of four selected Islamic banks of Malaysia. E-SERQUAL was modified by adding Shariah Compliance information about banks and products for Islamic banking customers. The finding specified that efficient & reliable services, fulfillment, security/trust, and Shariah compliance information have a significant association with the performance of Islamic banks. The research is original and its implications will be helpful for Islamic banks across the world to enhance the online experience of customers, which will help them to retain the customers in the rapid changing virtual environment.
