Due to the outbreak of the COVID-19, self-service technology is widely used in Korea, and demand for disposable cups is increasing significantly. Waste and recycling of disposable cups have become a social concern for Koreans and Korea implemented the "Disposable Cup Deposit Systems" again in December 2022. Whether the emergence of this system can change the way people behave in environmental protection is a question to be examined in this study. Companies participating in the disposable cup deposit system are hoping that customers will actively recover cups through self-service in the process of collecting disposable cups. The government, along with businesses, transfers recovery work to customers through self-service technologies and schemes. Due to the increase in Shadow Work and the strengthening of consumer environmental protection consciousness, this paper focuses on how unmanned service types such as self-service technology can affect people's environmental protection behavior. An empirical analysis with 477 samples examined how the characteristics of shadow work, perceived efficacy, environmental awareness, and ecological guilt affect user's environmental protection behavior. Perceived efficacy that acts as a mediator and ecological guilt that plays as a moderator are investigated. Although there have been many studies on the effects of shadow work on customer behavioral intentions before, it has been very rare to study the effects of shadow work perceived by people on environmental behavioral intentions from an environmental protection perspective. This study shows that the higher the perceived efficacy of consumers, the more people prefer self-service technology and the stronger the environmental protection behavior. Also, consumers' ecological guilt significantly moderates the relationship between environmental consciousness and eco-friendly behavior. It is expected that companies and governments will be able to understand the impact of shadow work on consumers' environmental protection behavior and further promote environmental protection by appropriate policies and marketing strategies.

In recent years, self-healing coatings have been the subject of increasing interest. The ability of such coatings to self-repair local damage caused by external factors is a major factor contributing to their attractiveness. Metals are extensively used in modern society in a range of applications from infrastructure to aircraft to consumer products. The protection of metals, primarily from corrosion has been an active area of materials science for many years. The aim of this review is the demonstration for recent progress achieved in the development of carrier-based self-healing coatings for the protection of metals. This review mainly covers the reports published after 2010. Two main types of carriers for corrosion inhibitors or healing agents-polymer capsules and porous composite inorganic nanoparticles-are described.

This paper proposed an ESD protection device that improved the current driving ability through Self-bias than the existing ESD protection device. The new proposed structure is based on the LRSCR structure and adds an N+ diffusion region, and reduces resistance by connecting the gate and the P+ diffusion region. As a result, it was confirmed that the proposed ESD protection device exhibits a trigger voltage of 11.8V and a holding voltage of 5.9V. It can be used in 5V applications for low voltage and is expected to have excellent current driving capability.

Purpose: The purpose of this study was to identify factors influencing patient privacy protection behavior among nursing students and examine the relationships between these factors. Methods: Participants in this study were 144 nursing students who have experienced clinical practice. The data were analyzed using descriptive statistics, one-way ANOVA, Scheffe test, Pearson's correlation coefficient, and multiple regression with IBM SPSS Win 23.0 program. Results: Professional self-concept and ethical values were factors influencing patient privacy protection behavior among nursing students. These variables explained 21.9% of the variance for patient privacy protection behavior. A higher level of patient privacy protection behavior was associated with higher levels of professional self-concept and ethical values. Conclusion: The findings demonstrate that strategies for enhancing patient privacy protection behaviors of nursing students should include methods for forming images of positive nurses and firming ethical values.

This study examined the effects of response-facilitating factors(Food-related Knowledge, Response-Efficacy, and Self-Efficacy) and response-inhibiting factors(Severity, Vulnerability, and Consumer Stress) on the consumer' behavior intention based on protection motivation theory, which explains the behavioral change to protect oneself. This study was conducted to reduce the customers' concerns regarding food safety accidents and introduce ways to make them more interested in food safety. A sample of 225 adults over 19 years of age was collected in February 2018 through a self-administered questionnaire. The results of the cognitive mediation process of protective motivation theory showed that the consumers' knowledge and self-efficacy which are response-facilitating factors, positively influence the behavioral intention. Severity and consumer stress were response-inhibiting factors. On the other hand, response-efficacy, which is a response-facilitating factor, and vulnerability, which is a response-inhibiting factor, did not influence the behavioral intention. Therefore, severity and consumer stress are response-inhibiting factors. The results were analyzed as a result of a behavioral change to protect oneself from food safety accidents. The applicability of the theory of protection motivation on the topic of food safety was also confirmed.

Recently, the application of paint protection films (PPFs) for automobiles having a self-recovery coating layer has been grown up. In this study, we report the evaluation results on the basic physical properties of a poly(vinyl chloride)- based PPF containing poly(urea-urethane) hybrid self-recovery coating layer. Depending on the main chemical composition and the thickness of poly(urea-urethane)-based coating layer for PPF, the self-recovery performance by an optical microscope and the stain resistance through color difference value are measured. To improve the surface properties and show its easy-cleaning effect against the polluted things, silicone-modified polyacrylate is introduced to the self-recovery coating composition. The contact angle of water on the coated surface is confirmed to show its hydrophobic surface. Finally, accelerated weathering test of paint protection film with poly(urea-urethane) hybrid coating layer is performed to check the possibility of discoloration and deformation due to long-term exposure on harsh condition.

The Personal Information Protection Commission has been promoting the adoption of co-regulation to replace/improve the existing self-regulation programs since 2022. While the Commission's co-regulation framework has received positive feedback for its contribution to address the regulatory issues, it has also faced criticism for being seen as "co-regulation in appearance only without any real differentiation from existing self-regulation." This study aims to examine the case of industry-specific co-regulation proposed by the Personal Information Protection Commission, with the objectives of 1) determining whether their approach can be categorized as a type of co-regulation with differentiation from the existing self-regulation programs, and 2) proposing improvements for successful regulation. The 'co-regulation' of the Commission can be classified as a form of co-regulation that differs with traditional self-regulation, as it involves government and private organizations collaborating to establish self regulatory codes reflecting industry-specific characteristics as well as provides interest groups with incentives to comply with the codes. The co-regulation framework is evaluated to some extent as successful, but there is still room for improvement in three major aspects. (1) When selecting the areas for co-regulation, a focus should be placed on areas where technological changes are rapid, and government regulations should be applied in areas where they are not. (2) It is necessary to enhance the expertise of regulatory agencies, and (3) ensuring the democratic nature of regulation, such as encouraging the participation of civil organizations, is necessary.

The European Union recently established the General Data Protection Regulation (GDPR) for secure data use and personal information protection. Inspired by this, South Korea revised their Personal Information Protection Act, the Act on Promotion of Information and Communications Network Utilization and Information Protection, and the Credit Information Use and Protection Act, collectively known as the "Three Data Bills," which prescribe safe personal information use based on pseudonymous data processing. Based on these bills, the personal data store (PDS) has received attention because it utilizes the MyData service, which actively manages and controls personal information based on the approval of individuals, and it practically ensures their rights to informational self-determination. Various types of PDS models have been developed by several countries (e.g., the US, Europe, and Japan) and global platform firms. The South Korean government has now initiated MyData service projects for personal information use in the financial field, focusing on personal credit information management. There is also a need to verify the efficacy of this service in diverse fields (e.g., medical). However, despite the increased attention, existing MyData models and frameworks do not satisfy security requirements of ensured traceability, transparency, and distributed authentication for personal information use. This study analyzes primary PDS models and compares them to an internationally standardized framework for personal information security with guidelines on MyData so that a proper PDS model can be proposed for South Korea.

위치기반 서비스에 관련된 기술 연구가 활발히 진행됨에 따라 다수의 사용자가 위치기반 앱 서비스를 이용하고 있다. 그러나 위치기반 앱 서비스를 이용하는 사용자가 점차 증가함에 따라 사용자의 위치정보가 노출될 확률이 높아지고 있다. 우리는 개인의 위치 정보를 보호하면서도 서버의 작업 부하를 줄일 수 있는 self-Privacy Protection Range (self-PR)을 제안한다. Self-PR은 클라이언트의 조건(ex. 배터리 상태, 모바일 기기의 성능 등)에 따라 보호 영역을 설정할 수 있기 때문에 이상적인 질의처리가 가능하다. 반면에 서버는 클라이언트의 self-PR이 증가할수록 서버는 데이터 탐색 경로가 짧아지기 때문에 작업부하를 줄일 수 있다. 그리고 서버는 클라이언트의 self-PR 확인하고 질의 결과를 전송하기 때문에 정확한 질의 결과를 전송할 수 있다.
