The purpose of this study was to investigate the structural relationship between environmental factors, personal factors, ease of use, usefulness and behavioral intention of delivery application by applying the extended Technology Acceptance Model (TAM). An online survey was conducted based on a self-administered questionnaire to a selected sample who had an experience of using delivery application at least once. The survey was conducted in September, 2017. The data obtained was analyzed using SPSS 24.0 for windows and AMOS 24.0. The findings of the study showed that among environmental factors, social influence had a significant effect on perceived usefulness and perceived ease of use and facilitating conditions had a significant effect on perceived ease of use only. Among personal factors, anxiety had a significant effect on perceived usefulness, while innovation had a significant effect on perceived ease of use. Both of perceived usefulness and perceived ease of use had a significant effect on behavioral intention. This study suggests the importance of environmental and personal factors for increase of behavioral intention of delivery application.

Background: In occupational studies, it is a known situation that technical and organizational attempts are used to prevent occupational accidents. Especially in the mining sector, if these attempts cannot prevent occupational accidents, personal protective equipment (PPE) becomes a necessity. Thus, in this study, the main objective is to examine the effects of the variables on the use of PPE and identify important factors. Methods: A questionnaire was implemented and structural equation modeling was conducted to ascertain the significant factors affecting the PPE use of mining employees. The model includes the factors that ergonomics, the efficiency of PPE and employee training, and PPE usage habit. Results: The results indicate that ergonomics and employee training have no significant effect (p > 0.05) on the use of PPE. The efficiency of PPE has a statistically meaningful effect (p < 0.05) on the use of PPE. Various variables have been evaluated in previous studies. However, none of them examined the variables simultaneously. Conclusion: The developed model in the study enables to better focus on ergonomics and employee training in the PPE usage. The effectiveness of a PPE makes its use unavoidable. Emphasizing PPE effectiveness in OHS training and even showing them in practice will increase employees' PPE usage. The fact that a PPE with high effectiveness is also ergonomic means that it will be used at high rates by the employee.

Microblog is emerging as a new communication service because of its usefulness and real-time accessability. Recently, microblog services, such as twitter and me2day in Korea, are getting a great attention. Continuous use intention is critical to sustain the service. However, most recent studies are based on Technology Acceptance Model(TAM) and Expectation Confirmation Model(ECM). These models are only focused on individual factors and overlook social influence factors. Social influence has been indicated as a critical factor of technology adoption and diffusion in social context(Davis, 1989; Fulk et al., 1987). In this study, we explore factors related to social influence which effect on continuous use intention for 'me2day' that is one of the most famous microblog in Korea. The purpose of this study is to understand continuous use intention and examine the relationship among social influence factors, social presence, and continuous use intention. To understand the phenomenon of continuous use intention in microblog service, this study employed social influence theory and expanded it by adding personal network exposure and group norm as additional social influence factors. The results show that social identity, group norms, and social presence positively influences continuous use intention. Contrary to our expectation, personal network exposure does not influence on continuous use intention. Academically, this research can contribute to microblog research field through elucidating the relationship among social influence factors, social presence, and continuous use intention. Although there is not enough research which is considered social influence factors as major explanation for continuous use intention, this study can give novel point of view to understand continuous use intention of microblog. Practically, service providers could consider ways to encourage users to continually use microblog service by reinforcing social influence factors and social presence.

핀테크 서비스 산업은 현재 전 세계적으로 ICT 기술을 기반으로 모바일 등 다양한 채널을 통해 금융 및 결제서비스의 혁신을 이끌며 빠르게 성장하고 있다. 국내에서도 간편결제 서비스를 중심으로 다양한 핀테크 서비스 산업이 형성되고 있다. 이러한 핀테크 서비스는 여러가지 보안 위협들이 존재하며, 그 중 개인정보 및 금융정보를 수집 이용함에 따라 이에 대한 정보 유출이나 프라이버시 침해 사고 가능성도 증가할 것이다. 이에 본 논문에서는 핀테크 서비스 중 간편결제 서비스를 대상으로 자신의 개인정보보호에 대한 합리적인 선택을 하는 이용자들(Privacy Pragmatists)에 대해 해당 서비스를 이용 및 선택 시 개인정보보호에 대한 자가평가를 할 수 있도록 평가항목을 도출하며, 이를 통해 향후 핀테크 서비스의 개인정보 보호를 위한 보안 정책을 제언하고자 한다.

스마트폰의 대중화 보급은 모바일 인터넷 사용자를 증가시켰고 이로 인해 모바일 전자상거래 서비스도 급속히 성장하고 있다. 이런 급격한 성장과 더불어 모바일커머스 사용자의 보안 및 개인정보유출에 대한 불안감도 더욱더 커지고 있다. 따라서 모바일커머스의 지속적인 확대와 성장을 위해서는 보안과 개인정보보호가 무엇보다 중요하다는 인식하에 보안과 개인정보보호가 사용자의 모바일커머스 사용의도에 미치는 영향력을 심도 있게 분석하고자 하였다. 이에 본 연구에서는 모바일커머스 방문 경험자를 중심으로 설문조사를 하여 보안과 개인정보보호 인식이 지각된 위험과 지각된 신뢰, 사용의도 간에 미치는 영향을 분석하였다. 연구결과, 보안과 개인정보보호는 모바일 상거래에 대한 불안과 불확실성을 감소시킴으로써 사용자들의 모바일커머스에 대한 신뢰향상에 기여하며, 이런 결과가 사용의도를 높이는 심리적 기제에 영향을 미치는 중요한 요인으로 나타났다.

금융회사가 개인정보를 수집하기 위해서는 법률에 정해진 내용을 소비자에게 명시적으로 알리고 사전 동의를 받도록 되어 있다. 그 결과 금융상품이 복잡해지고 다양해짐에 따라 '개인정보제공 동의서' 내용도 복잡해지고 분량이 많아지게 되었다. 특히 인터넷과 모바일의 경우 화면 크기의 제약으로 글씨가 더 작아지면서 더욱 이해하기가 힘들어졌다. 이것은 개인정보를 수집하는 거의 모든 기업이 비슷한 상황이어서, 서비스를 이용하는 소비자 입장에서는 동의 내용을 이해못한 채 습관적으로 동의하는 모순이 생기고 있다. 본 연구에서는 금융회사 인터넷 홈페이지를 통한 합리적인 개인정보 수집 및 이용 동의 정책 수립 모델을 제시하기 위해 국내외 법제도를 고찰하여 문제점을 도출하고 개선 방안을 제시한다. 또 연구를 통해 선정된 평가요인을 AHP(Analytic Hierarchy Process)방법을 이용하여 의사결정 모델과 공식을 제시하고 검증한다.

개인정보보호법 등 데이터 3법 개정에 따라 통계작성, 과학적 연구, 공익적 기록보존 등을 위해서는 정보주체의 동의 없이 가명정보 처리가 가능하며 개인정보와 달리 개인정보 유출통지 및 개인정보 파기 등의 법적용 예외조항을 두고 있다. 가명정보는 국가별로 가명처리에 대한 기준이 상이하며 국내에서도 개인정보 비식별 조치 가이드라인에 비식별조치와 익명화를 동일시하고 있다는 점에서 개정이 필요하다 할 것이다. 본 논문에서는 4차 산업혁명에 따라 개인정보의 활용에 초점을 두고 새롭게 도입된 가명정보의 안전한 활용을 위해 가명정보의 개념을 살펴보고 국내외 비식별조치 기준과 가명정보의 생성/이용/제공/파기 단계에서 법 또는 시행령(안)의 주요내용 검토를 통해 향후 추진되는 관리적/기술적 보호조치 방안에 대한 제언을 하고자 한다.

Personal NO$_{2}$ expousre and time activity patterns were measured during March, 1991 for 46 taxi drivers in the Seoul area. Badge-type personal samplers were worn for 24 hours by taxidrivers for monitoring personal expousre to NO$_{2}$. A standard respiratory questionnaire was administered and pulmonary function test was performed using a protable spirometry. The mean concentrations of personal NO$_{2}$ expousres of taxi drivers were 0.55ppm. Personal NO$_{2}$ exposures of taxi drivers were seemed to be higher in longer period of driving, smokers, and use of LP gas in homes. Prevalence rate of respiratory symptoms and the level of pulmonary function(FEV$_{1.0}$ and FVC) seemed to be related to higher personal NO$_{2}$ concentrations. It is concluded that persoanl NO$_{2}$ expousres of taxi drivers are probably affected by indoor NO$_{2}$ levels of a tax/and their common activities.

In Internet of Things (IoT) era, more diverse types of information are collected and the environment of information usage, distribution, and processing is changing. Recently, there have been a growing number of cases involving breach and infringement of personal information in IoT services, for examples, including data breach incidents of Web cam service or drone and hacking cases of smart connected car or individual monitoring service. With the evolution of IoT, concerns on personal information protection has become a crucial issue and thus the risk analysis and management method of personal information should be systematically prepared. This study shows risk factors in IoT regarding possible breach of personal information and infringement of privacy. We propose "a risk analysis framework of protecting personal information in IoT environments" consisting of asset (personal information-type and sensitivity) subject to risk, threats of infringement (device, network, and server points), and social impact caused from the privacy incident. To verify this proposed framework, we conducted risk analysis of IoT services (smart communication device, connected car, smart healthcare, smart home, and smart infra) using this framework. Based on the analysis results, we identified the level of risk to personal information in IoT services and suggested measures to protect personal information and appropriately use it.
