Daily monitoring of the heart rate can facilitate detection of heart-related diseases in their early stages. Therefore, providing an easy-to-use and noninvasive heart rate monitoring system has been a very popular research topic in the field of healthcare. One of good candidate methods is to use commonly available cameras and extract information that can help to estimate heart rate from a human face. Generally, such information can be retrieved using two different approaches: photoplethysmography (PPG) and ballistocardiography (BCG). PPG exploits slight color changes caused by blood volume variations during heartbeats; thus, it tends to be vulnerable to unstable lighting conditions. BCG exploits subtle head motions caused by pumped blood travelling through the carotid artery during heartbeats; thus, it is vulnerable to the voluntary head movements that are not related to heartbeats. Nevertheless, most related works use either to estimate the heart rate. In this paper, we propose to combine two approaches to be robust to challenging conditions. Specifically, we explore possible ways to combine raw signals obtained from two approaches and verify that the proposed combination shows better accuracies under challenging conditions, such as voluntary head movements and ambient lighting changes.

Purpose: This study aimed to conduct a scoping review of studies on interventions for the prevention of safety accidents involving infants. Methods: The scoping review method by Arksey and O'Malley was used to conduct an overview based on information spanning a wide range of fields. Multiple electronic databases, PubMed, CINAHL, RISS, and KISS, were searched for articles written in English or Korean published from 2012 to the present on safety accident prevention interventions. A total of 2,137 papers were found, and 20 papers were ultimately analyzed. Results: Most studies were conducted in the United States (55.0%) and in the medical field (45.0%), and most were experimental studies (35.0%). The results were organized across five categories: 1) preventive precautions, 2) characteristics of children's developmental stages, 3) encouraging voluntary participation, 4) continuity of interventions, and 5) teaching methods. Conclusion: Safety accident prevention interventions should cover the establishment of a safe home environment, include voluntary participation, and provide routine follow-up interventions. Additionally, practical training and teaching methods that incorporate feedback rather than a lecture-oriented approach should be adopted.

Purpose - There is a paucity of literature dealing with exporters' compliance issues in e-commerce exports. This study aims to fill this gap in the literature by exploring customs initiatives to facilitate the e-commerce exports of small and medium-sized enterprises (SMEs) in the changed compliance environment. The central question of this study was divided into five subquestions: first regarding the pros and cons of trade facilitation measures for Korean e-commerce export clearance; second and third questions about risk and compliance management for facilitation fourth about instruments, the changes in Korean SME compliance burden in e-commerce exports, and ways to improve trade facilitation for e-commerce exports. Design/methodology - This study adopts a qualitative approach using a case study method to understand the SME experience in Korean e-commerce export compliance procedures. A qualitative method was selected to answer research questions requiring an in-depth understanding of the regulatory procedures of customs administration and exporters' compliance burden. Because this study addresses the changing compliance environment for which statistical data is insufficient, a quantitative method is considered inappropriate. Based on the approach, data were collected using multiple sources, including an extensive literature review, interviews, and field observations. Thematic pattern matching was applied to interpret the data. Findings - This study examined ways to support SMEs in the changed e-commerce export compliance environment. Facilitation measures for e-commerce exports have contributed to SME access to global markets, simplifying export clearance procedures, and saving exporters' compliance costs. However, such instruments are limited in promoting SME compliance capabilities to cope with intensified competition and strengthened controls over foreign exporters in cross-border e-commerce. Therefore, this study highlights the importance of reshaping facilitation measures for e-commerce exports based on risk and compliance management theories to a system encouraging exporters' voluntary compliance. Originality/value - This study's academic significance derives from verifying the relationship between trade facilitation instruments and risk and compliance management procedures using an actual case in Korea. It is also of practical importance in navigating the directions for improving facilitation measures for e-commerce exports in a changed compliance environment.

Recently crime against children is emerged as a serious social problem. Children should be protected in social. However, they have become major targets of the crime, as sexual abuse, abduction, abuse, domestic violence, school violence and so on. To solve these problems, it is important to educate crime prevention for children all above. Entertainment is one of the edutainment's elements. It attracts voluntary participation, immersion, and continuous learning from children. Edutainment contents for prevention of crime against children are far less fully studied than that of school subject as Mathematics, English, and so on. There is no serious study on edutainment contents for prevention of crime against children, as well as base study and approach way. Now more than ever, safety needs are strongly demanded in society. Accordingly, study on edutainment contents for prevention of crime against children have been demanded more than ever. In this paper we shall see basic approach principles and planning process of web-based edutainment contents for prevention of crime against children. This study lays the foundation for future work on edutainment contents for prevention of crime against children.

Along with the uprising of sustainability issues in the field of business and management, firms increasingly strategize and mobilize resources towards sustainability related activities and processes much more than ever. Together with this phenomenon, the concept of corporate sustainability has been noticed much more by scholars and practitioners from diverse fields. However, differently with an expectation, it is undoubted that there is a small controversy when we treat the issues related to its definition, antecedents, consequences, processes and so on. Based on this kind of understanding, this study tries to suggest and advance a new approach to the corporate sustainability based on the premises of social capital theory for social relations, which explains the role of institutions, and norms that shape firms 'social interactions. Main argument is that firm's voluntary, progressive, and proactive activities for sustainability issues can be understood as the firm's social capital building processes. Though there are a little existing study dealing with this issue, this study has a difference with them by proposing social capital building issues based on firm's real activities. Finally, case analyses based on a new approach are suggested and the theoretical considerations with some limitations are explained.

본 연구에서는 낙동강 하구의 대포천에서의 주민운동을 분석하여 지역사회가 주도하는 환경운동이 특정 조건이 충족된다면 성공적인 환경관리를 할 수 있는 대안이 될 수 있음을 보여준다. 지역사회기반 환경보호(Community-Based Environmental Protection)는 다양한 명칭으로 표현되고 있으나 지역주민의 주도 하에서 환경보호 및 개선을 이룩하는 것으로 지속가능한 사회를 달성할 수 있는 유용한 환경관리 방안으로 이론적인 지지를 받고 있다. 이 방법은 정부의 강압적인 규제보다 효과적일 수 있으며 지역사회의 다양한 욕구와 환경문제를 동시에 고려하게 되는 장점도 있다. 그러나 이러한 지역기반환경운동이 실재 전개되어 성공하는 경우는 흔하지 않다. 그런데 낙동강 하류의 대포천 사례는 지역주민의 환경규제반대운동이 결국에는 주민의 자발적인 수질개선운동으로 발전하여 실질적인 수질개선효과를 창출하였다. 뿐만 아니라 낙동강특별법의 제정 시에 제도화되어 수질환경정책의 발전에도 기여한 특별한 사례이다. 본 연구는 대포천 사례를 우리나라 수질관리정책의 종합적인 체계와 연계시켜서 살펴보면서 대포천 인근지역주민의 수질개선운동의 단계적 전개과정을 살펴보고 이 운동이 성공할 수 있었던 요인을 분석하고 있다.

Purpose Compliance support system (CSS) aims to support employees' voluntary compliance activities, however, it requires a different approach from the acceptance of other general information systems. In other words, the user's concern that his/her compliance activities recorded in the system are monitored may hinder the active use of the system. In this regard, we set up a research model to investigate the factors that affect the intention to use CSS, by including perceived usefulness, compliance commitment, and surveillance concern. Design/methodology/approach A questionnaire survey was conducted for the employees of a domestic oil-company, who operates their own CSS. Based on the 865 data collected, a structural model analysis using PLS was conducted. As a result, all four hypotheses were accepted. It was found that perceived usefulness of CSS has a positive effect on the intention to use CSS. Compliance commitment has a positive effect both on perceived usefulness and intention to use CSS. In contrast, surveillance concern of one's non-compliance recorded in the CSS was shown to have a negative effect on the relationship between compliance commitment and perceived usefulness. Findings This study has academic implications in that it extends the viewpoint of the existing technology acceptance mechanism by examining the two aspects, i.e., compliance commitment and surveillance concern. This study may also provide practical directions to strengthen the use of the active compliance support system by the employees.

This article explores the risk governance of nanotechnology in Korea in light of a regulatory law approach, a soft law approach, and a participatory governance approach. The risk governance of nanotechnology in Korea has three characteristics. First, there are many existing regulatory laws that can be applied to the regulation of nanotechnology. However, these laws have exemptions, the extent of which are larger than that of the Europe and the United States. Second, the soft law approach is the most prevalent risk policy in Korea at present, but is limited because it is being driven by the government without active, voluntary participation of relevant companies. Third, no case of participatory governance took place when it comes to nanotechnology technology assessment. As policy recommendations to improve Korean nanotechnology risk governance, this article suggests pre-market screening, mandatory governmental registration of nanomaterials, transition management of code of conduct, and the design of interdisciplinary research and development project for real-time technology assessment.

The purpose of this study is to examine direct and the indirect path of social leisure activity to life satisfaction of the elderly, through comprehensive approach. I analyzed data collected 531 old people in Seoul metropolitan area on SPSS 18.0 and AMOS 7.0 It was found that the participation in any social leisure activity including leisure program, voluntary activity, religious activity and bonding networks impact indirectly to the old people's life satisfaction through the leisure satisfaction and loneliness. However, only one activity, voluntary activity, impacted directly to life satisfaction. The leisure satisfaction and loneliness played partial-mediation role between voluntarily activity and life satisfaction. From the results of this study, we can know the policy to life satisfaction for the elderly in aging society and the strategies to manage the leisure programs in social welfare agencies for the elderly.

Objectives: This paper aims at addressing the importance of community-based health promotion. It would identify the origin of community health programs in Korea, which emphasized community involvement. And it would reveal the discontinuity of community-oriented health programs in the current health promotion activities. Finally, the methods of attaining community-based health promotion would be suggested. Results and Conclusion: Community-based health promotion had been implemented in rural areas by medical schools in the 1970s and 1980s, which emphasized the role of village health workers. But their roles has disappeared since the government-initiated health promotion policies and programs have been implemented in the mid-1990s. This paper addressed the factors contributing to this discontinuity, such as the expansion of heath insurance system, the change of health care discourses, the monopoly of resources for health promotion by government, and the bureaucratic approach to health promotion, etc. This paper suggested the utilization of voluntary and civic organizations in community for realizing the goal of community-based health promotion.
