We introduce a personal identification method which can find user's ID without any help of the user. To do this, there has been two approaches, vision-based and pressure-based. Pressure-based approach has some advantages compared than vision-based one in the aspects of illumination, occlusion, and the amount of data. In the previous study about pressure-based personal identification, there are some restrictions about human body posture for extracting normalized footprints. Since this approach cannot be extended unconscious and continuos identification, we suppose more natural method and verified it by experiments.

Climate change has resulted in increased frequency and intensity of heat waves, which poses a significant threat to the health and safety of construction workers, particularly those engaged in labor-intensive and heat-stress vulnerable working environments. To address this challenge, this study aimed to propose an interpretable machine learning approach for forecasting personal heat strain by considering the cumulative effect of heat exposure as a situational variable, which has not been taken into account in the existing approach. As a result, the proposed model, which incorporated the cumulative working time along with environmental and personal variables, was found to have superior forecast performance and explanatory power. Specifically, the proposed Multi-Layer Perceptron (MLP) model achieved a Mean Absolute Error (MAE) of 0.034 (℃) and an R-squared of 99.3% (0.933). Feature importance analysis revealed that the cumulative working time, as a situational variable, had the most significant impact on personal heat strain. These findings highlight the importance of systematic management of personal heat strain at construction sites by comprehensively considering the cumulative working time as a situational variable as well as environmental and personal variables. This study provided a valuable contribution to the construction industry by offering a reliable and accurate heat strain forecasting model, enhancing the health and safety of construction workers.

The purpose of this study is to review previous domestic and foreign studies and to investigate personal work-life harmonization through theoretical research on familyfriendly management using a dual agenda approach. The authors briefly identified trends and critically reviewed domestic researches on family-friendly management and foreign studies of scholars that overcame the limitations of domestic studies to present a foundation for work-life harmonization through a dual agenda approach. As a result, the existing family-friendly management was found to be compatible with work and family but was not effective in developing personal careers. The workers who actively accepted family-friendly management as part of their work-life balance were mostly female laborers who were employed part-time, had lower academic education, earned lower wages and, in general, were non-professional workers without specific skills or career aspirations. The remainder of the workers, full-time male employees, with higher education and with professional knowledge and skills, inevitably worked longer, more labor-intensive hours, due to the advent of the dual agenda approach. A new work-life harmonization program is urgently needed not only for family-friendliness but also for healthy organizations, individual career development and personal wellbeing.

Character education is an important educational purpose in the current situation of secondary mathematics education. In the current mathematics curriculum, character education is mentioned in terms of core competencies. However, it is very difficult to concretely practice character education in secondary mathematics education. This paper examines the theoretical background of character education in the tradition of mathematics education, and suggests that mathematics is regarded as a practical tradition by the nature of mathematics from a value-intrinsic perspective. In this respect, mathematics education is defined as an intrinsic and nurturing character through long history of practice. This paper searched for an integrated approach to practicing character education in of secondary mathematics education, and argued that the teacher's personal approach including the class model approach of the human factors by an example of the exponential law a^maⁿ = a^m+n and the value-oriented activities according to the nature of the mathematics was the core.

Recently, the demand for the use of personal mobility vehicles, such as an electric kickboard, is increasing explosively because of its high portability and usability. However, the number of traffic accidents caused by personal mobility vehicles has also increased rapidly in recent years. To address the issues regarding the driver's safety, we propose a novel approach that can monitor context information around personal mobility vehicles using deep learning-based object detection and smartphone captured videos. In the proposed framework, a smartphone is attached to a personal mobility device and a front or rear view is recorded to detect an approaching object that may affect the driver's safety. Through the detection results using YOLOv5 model, we report the preliminary results and validated the feasibility of the proposed approach.

The strength or resilience of refugees is a less emphasized area as the discourse in refugee mental health study mainly weighs on pathologizing the effects of refugee experiences. Within the lenses of strength and resilience, this study explored how refugees and asylum seekers, who experienced violence and loss, coped with trauma and hardship in their newly established lives in South Korea. In this study we analyzed survey data collected from 100 participants (55 asylum seekers and 45 refugees) through open-ended questions. We analyzed narratives for both content and form and provided evidence for factors that reflect coping strategies used by participants to overcome their life adversities. The findings gave rise to; (a) character traits like strong religiosity, personal determination, patience to forbear, hopefulness, and peaceful acceptance of current circumstance; (b) relationships, in the sense of meaningful strong bonds within family members and the instinctive personal resourcefulness to utilize support resources within and outside of their communities; (c) learned skills after migraing to korea; (d) knowledge sets in how to get by in korea; (e) personal talents, and (f) extra abilities that gave power to pass socio-economic difficulties. The findings underscore the importance of considering the strength-based approach either in discussing resilience or intervention. Our approach will allow practitioners to acknowledge that refugees and asylum seekers potentially have a unique set of strengths and abilities that they rely on to overcome their immediate and future problems. It will also guide practitioners as they devise their intervention schemes.

지식정보사회가 고도화되어가며 개인정보가 가지는 가치와 중요성은 더욱 증가하게 되었다. 최근 빅데이터 기술 발달과 클라우드 환경의 보급에 따라 개인정보의 침해나 유출 가능성은 증가하였으며, 공공부문의 다양한 정보를 개방하고 공유하려는 시도는 정보 활용을 통한 가치창출 가능성을 높여주고 있다. 이러한 개인정보에 대한 논의가 진행되어온 연구경향을 분석하기 위하여 2000년부터 지금까지 논의된 연구논문과 보고서를 중심으로 연구자가 설정한 분석기준에 따라 분석하였고, 그 결과에 기반을 둔 몇 가지 제언을 정리하였다. 이를 간략히 보면, 첫째, 개인정보 연구가 질적 법제도적 차원에서 정보보호를 주로 강조하면서 논의되어 왔다. 둘째, 개인정보의 중요성에도 불구하고 정부기관이나 국책연구원에 비해 학계에서의 심도있는 논의가 부족하였다. 셋째, 실태파악이나 현황조사 수준에서 진행된 경우가 다수를 차지하고 인과관계나 영향요인을 분석하려는 연구는 많지 않았다. 향후 개인정보 연구를 보다 발전적으로 진행하기 위해서는 개인정보 자체에 대한 체계적이고 심도있는 접근, IT패러다임의 변화에 맞는 연구범위의 확대, 계량적 방법 등 다양한 연구방법론의 적용과 학제간 연구 활성화, 공공부문 뿐만 아니라 민간부문에서의 개인정보 사용과 관리에 대한 다양한 연구가 필요하다.

Purpose: This study aims to examine the relationships among social discrimination, subjective health, and personal satisfaction based on the country of origin. Methods: The analysis was based on 16,958 immigrants who participated in the National Survey of Multicultural Family 2015 in Korea. This study conducted stratified cross-analysis of social discrimination for the differences in subjective health and personal satisfaction. Multivariate-adjusted odds ratios and 95% confidence intervals for the relationships among social discrimination, subjective health, and personal satisfaction were examined with multivariable logistic regression. Results: There were differences in experience of social discrimination, subjective health status, and personal satisfaction according to the country of origin. Groups without the experience of social discrimination had better subjective health and personal satisfaction than the other groups. Conclusion: This study demonstrates that a discrimination prevention program needs to be developed based on a cultural approach.

This study examined how pre-service elementary teachers' perceptions regarding the learning environment (learning focus/ability-meritocracy/cooperative climate) and achievement goals (mastery/performance-approach/performance-avoidance) in science education courses jointly contributed to their science teaching efficacy beliefs (personal science teaching efficacy belief/science teaching outcome expectancy). A path analysis supported a causal model in which the perception of the learning focus influenced the mastery goal, which in turn influenced the personal science teaching efficacy belief and science teaching outcome expectancy. The perception of learning focus also had a direct effect on science teaching outcome expectancy. The perception of ability-meritocracy influenced personal science teaching efficacy belief via the performance-approach (positively) or, conversely, the performance-avoidance goal (negatively). No link .was deduced from the perception of cooperative climate. The educational implications of these findings were also discussed.

The release of relational data containing personal sensitive information poses a significant risk of privacy breaches. To preserve privacy while publishing such data, it is important to implement techniques that ensure protection of sensitive information. One popular technique used for this purpose is data perturbation, which is popularly used for privacy-preserving data release due to its simplicity and efficiency. However, the data perturbation has some limitations that prevent its practical application. As such, it is necessary to propose alternative solutions to overcome these limitations. In this study, we propose a novel approach to preserve privacy in the release of relational data containing personal sensitive information. This approach addresses an intuitive, syntactic privacy criterion for data perturbation and two perturbation methods for relational data release. Through experiments with synthetic and real data, we evaluate the performance of our methods.
