Due to the changes in market place, new business types(e.g. e-business) have been rapidly emerged and increased. However, those new business types have not much been emerged n shipping and port related industries, and adoption rate of e-business in this area is very low, compared to other industries. Thus, to promote e-business in this area. many policies have been studied. However, most of previous studies have not been based on industrial structure, and results of these studies have mostly been case by case. Further, there have been no research based on the related theories. As a result, despite many of research and project for shipping and port related e-business, prominent achievements in this area have never to be presented. For these reasons, it can be stated that, first of all, basic studies related to new business types in shipping and port are needed. For these reasons, it can be stated that, first of all, basic studies related to new business types in shipping and port are needed, and then, various policies based on results of those basic studies should be discussed. The aim of this study is to classify business types existed (or expected) in a port related industry, ship bunkering. This taxonomy was based on theories related to business layer(BL) and value chain(VC), and these BL and VC combination enabled to acquire all possible business types.

This study aims to investigate the antecedent of consumer personal preventive equipment purchase behaviour by extending the HBM model after the pandemic. Pandemic related studies have focused on the effect of perceived susceptibility and perceived severity on consumer preventive behaviour, little studies have investigated the antecedents of consumer perceived risk. This study filled the gaps in the previous studies. This study tested all proposed hypotheses among users who have purchase the self-preventive behaviour. In final 253 valid data were collected through online survey for statistics analysis. This study found that consumer's health consciousness significantly impacted consumer's perceived severity of COVID-19 and perceived risk. Perceived risk positively impacted consumer self-preventive equipment purchase intention. In contrast, perceived susceptibility did not significantly consumer perceived risk. Based on these results, the theoretical implication will be offered on the study of health-related studies and will be given insight for disease control center to effectively manage consumer self-preventive behaviour.

본 연구에서는 한국어 SNS 대화에서 나타나는 문장들의 감성을 분석하고자 신경망 모델을 활용하여 시스템을 구축하였다. 현재 해외 SNS 감성분석에 대한 연구는 많이 진행된 상황이지만, 한국어 범용 대화에 대해 적절한 모델이 무엇인지는 연구가 부족한 실정이었다. 따라서 한국어 대화에 적합한 모델을 채택해 보다 정확한 감성분석을 수행하였다. 이를 위해 한국어 SNS 대화 데이터에 대해 신경망 모델을 적용하여, 82% 성공률로 기존 모델 72% 성공률보다 훨씬 더 우수한 성능을 보였다. 또한 본 연구의 결과는 악플 추적 등 실용적인 분야에도 기여할 수 있다고 사료된다.

이 연구는 대기오염과 미세먼지의 각 성분이 질환에 미치는 영향에 대한 데이터만 존재한다면 어떠한 질환이든 위험도 예측 결과를 알 수 있는 것에 의미가 있다. 또한 기존의 대기정보에 따른 정보를 예상하는데 필요한 데이터 종류와 수가 많았으며 계산의 복잡성이 높았고 정보의 제공 범위가 넓었다. 하지만 이 연구는 과거 대기 데이터와 딥러닝을 통해서 낮은 비용으로 더욱 자세하게 유해질환 위험도를 예측하는 시스템을 구축하였다. 이 연구에서 구축한 시스템은 예측 결과 88.9%의 정확도를 보였다. 이 시스템은 입력되는 데이터의 정보에 따라 세분화된 지역의 대기환경 정보 또한 파악 가능하며 그 과정이 매우 간편하고 유용하다. 이 시스템은 공기질 예측을 위해 유용하게 사용될 수 있을 것이라고 사료된다.

In this study we tried to measure the user satisfaction with IT in small firms. Though the number of small firms is not negligible, most studies on the IT satisfaction focused on medium and large-sized firms. Using Palvia's model in 1999 we measured If satisfaction of the employee in small firms in the manufacturing and telecommunication industry. We included seven constructs such as S/W pertinence, information content and accuracy, information format, system usefulness, system continuance, and system support to measure IT satisfaction. The result suggests that the If users in small firms are generally dissatisfied with the information technology and the areas of deep dissatisfaction are system usefulness and system support. Type of business, the gender and education of the users are found to affect the level of satisfaction.

This study is for understanding what is the significance and ethics of business in the Ukiyozoushi Seken Tedai Katagi written by Ezima Kiseki in Edo era. There were many merchants called Tedai in Seken Tedai Katagi, and they worked for their owners and the family(家). Tedai thought the business was not for themselves. Their attitudes seemed almost same as the loyalty of chivalry to the lord, so the merchants themselves thought business was not so different from the chivalry's conduct. Then the merchants thought business ethics were changeable, because the result of business was more important than the process of business. If the merchants earned the money by unethical conduct, the business could be eulogized by case, because the earning money was not for themselves but for the owner and the family ultimately. On the other hand, the business was also built up from trust, repute, etc. in Seken Tedai Katagi. So the business was not only the hylic conduct but also the mental conduct for the merchants, then the idea showed the business was not the social ills. In the Edo era, the chivalry and the Confucianists thought the business was social ills, so the merchants should build up the significance and ethics of business by themselves. Seken Tedai Katagi was the one of the cultural conduct to build up the significance and ethics of business of merchants', as we could see them in the stories.
