Some groups do ethical activities (such as ethical slogan t-shirt campaigns) only to complete the requirements for ethical duty; consequently, some people question the effectiveness of those products. The attributes of ethical slogan t-shirts should be considered seriously to reduce skepticism when planning a campaign. Researchers can also suggest a new purpose for ethical t-shirts using an ethical message. In study 1, we conduct a conjoint analysis that suggests realistic multi-attribute choice decisions. The suggested multi-attributes wear design aesthetic (high/low), price (high/low), where we donate (close/far), and the size of firm (big/small). In addition, participations were divided into two groups according to eco-friendly attitudes to confirm differences in choices between two groups. Study 1 showed that price is the most important attribute, but design aesthetic also remains important. In addition, a group that has a high eco-friendly attitude thought "where we donate" was more important than other groups. In study 2, a pre-post approach investigated wearers' attitude changes. We also divided participants into two groups and one group wear high level design aesthetic t-shirts (and vice-versa) to measure the attitude change difference. As a result of study 2, the wearers partially changed their eco-friendly attitudes. The group that wore high design aesthetic t-shirts showed a greater difference than other groups. Through this study, we conclude that customers seriously considered the design aesthetic. Finally, wearing ethical slogan t-shirts can change the attitudes of wearers.

The primary objective of this study was to employ Darden's store patronage model in order to investigate the role that shopping orientation and store attributes play in store patronage. The study sample consisted of 340 female university students residing in Seoul. The data was analyzed by using path analysis and factor analysis. The recreational shopping orientation played a greater role in influencing the importance of store attributes than did the convenience shopping orientation. Recreational shoppers want a variety of brands and convenience shoppers can be attracted by a convenient location and availability of parking. Six important store attributes(variety of products and price level, proximity, variety of trendy brands, store decor, sales promotion, sales personnel) have a differential influence on store patronage. Shopping orientation was a direct predictor of patronage behavior and mediated the relationship between shopping orientation and store attribute importance. The finding indicated that both the recreational shopping orientation and convenience shopping orientation can be used effectively to position store patronage in such a way as to provide a strong means for shoppers to satisfy their needs. The findings of this study demonstrated that South Korean female shoppers with different shopping orientation have different store attribute preference and store patronage. The results provide a basis for building a successful strategy to attract shoppers and generate sales. The study focused on a specific product category, i.e., women's apparel. To meet the needs of female apparel shoppers, further research is needed to learn more about the distinctive characteristics of Korean consumers that could be applied to a variety of jobs, ages and living areas.

Blockchain technology can provide a high level security based on a decentralized distributed ledger and consensus-based structure. In order to increase the utilization of blockchain technology, it is necessary to find a way to use it in fields that require personal data processing such as health care and e-commerce. To achieve this goal, the blockchain based system should be able to comply with data privacy regulations represented by European Union(EU)'s GDPR(General Data Protection Regulation). However, because of the properties of the blockchain like the immutability and decentralized recorded data, it is difficult to technically implement the requirements of the existing privacy regulations on the blockchain. In this paper, we propose a multi-chain based access control system that can guarantee the rights of the personal data subject required by GDPR by utilizing Chameleon Hash and Attribute Based Encryption (ABE). Finally, we will show through security analysis that our system can handle personal data while maintaining confidentiality and integrity.

Recently the ground settlement has been increasing in urban area according to development. And, this may attribute a groundwater level drawdown. This study presents an analysis of groundwater level drawdown for circular vertical shaft excavation of ｢◯◯◯◯ double track railway build transfer operate project｣. And, in-situ monitoring data and numerical analysis were compared. So, if we examine the groundwater level drawdown in design, ground conditions should be applied so that the site situation can be reflected. And, groundwater level should be considered a seasonal measurement in order to apply the appropriate groundwater level. It was confirmed a similar predicted value to groundwater level drawdown of in-situ monitoring data.

We propose an extended relational data model which can represent the reliability of data. In this paper, the reliability of data is defined as the reliability of the source, from which the data originated. We represent the reliability of data at the level of attribute values, instead of tuples, then define the selection, product and join operators.

In any mobile ad hoc environment, collision amongst mobile objects is always likely to occur unless there is a certain level of intelligence to detect and avoid the collision. This phenomenon of detection and avoidance is the key attribute for safety applications in vehicle to pedestrian (V2P) communications systems. In this paper, we propose a V2P communications concept for collision detection and avoidance.

컴퓨팅 환경이 유리쿼터스 환경으로 변해가면서 다양한 컨텐츠와 다양한 디바이스들이 등장하게 되었고, 디지털 컨텐츠를 보호하기 위해 DRM(Digital Rights Management) 기술이 적용된 서비스가 제공되고 있다. 그러나 현재 DRM 기술의 디지털 컨텐츠 보안 정책은 일정한 키 길이에 동일한 암호 알고리즘을 사용함으로써 비효율적이고, 사용자의 다양한 요구를 만족시키지 못하고 있다. 본 논문에서는 디지털 컨텐츠에 보안 정책을 효율적으로 적용하고 디바이스의 성능과 디지털 컨텐츠의 가치에 따라 의사 결정 방법인 MAUT(Multi-Attribute Utility Theory) 알고리즘을 이용하여 최적의 보안 등급을 동적으로 결정하는 컨텐츠 암호화 모듈을 설계하고 구현한다.

Classification and Coding(C&C) systems as a core of design information management have been accomplished by many studies in terms of design and manufacturing attribute based on Group Technology. Those are very difficult to apply in make-to-order(MTO) manufacturing because the environment of MTO has various characteristics of product, many licensors, engineering change, insufficiency of integrated management system for codes and so on. This paper presents a suitable C&C system to MTO manufacturing which consider management level and drawing.
