  • The main purpose of this research is to examine the relation of variables related to the worker's stress symptoms and coping. The influence of emotional support(from family, colleague, and boss), self-efficacy (self-regulatory, social, relational, resiliency, and management of work), job-satisfaction, and job-performance on worker's stress symptoms and coping is analyzed. Participants were 559 teachers (elementary 205, junior high 203, senior high 151; male 132, female 427). The results were as follows: There were no significant differences in stress symptoms and coping among primary, junior and senior high school teachers. On the other hand, there were significant differences in stress symptoms and coping between male and female teachers. Female teachers experienced more stress symptoms than male teachers. At the same time female teachers coped more efficiently in stress situation than male teachers. With emotional support, self-efficacy, job-performance and job-satisfaction as independent variables, the result of multiple regression showed that job-satisfaction has a negative influence on stress symptoms. Positive influences on stress coping was found for resiliency of self-efficacy in case of male teachers, and in case of female teachers resiliency of self-efficacy, emotional support from colleague, job-performance, and emotional support from family. Therefore, regardless of the gender of the teachers, high job-satisfaction decreased stress symptoms and high resiliency of self-efficacy increased efficient stress coping. As for female teachers, not only resiliency of self-efficacy but also emotional support from colleague and family, job-performance contributed to coping with stress.

  • Software development involves a series of stages, including requirements analysis, design, implementation, unit testing, and integration testing, similar to those used in the system engineering process. This study utilized MathWorks' model-based design platform to develop multi-function radar software and evaluated its feasibility and efficiency. Because the development of conventional radar software is performed by a unit algorithm rather than in an integrated form, it requires additional efforts to manage the integrated software, such as requirement analysis and integrated testing. The mode-based platform applied in this paper provides an integrated development environment for requirements analysis and allocation, algorithm development through simulation, automatic code generation for deployment, and integrated requirements testing, and result management. With the platform, we developed multi-level models of the multi-function radar software, verified them using test harnesses, managed requirements, and transformed them into hardware deployable language using the auto code generation tool. We expect this Model-based integrated development to reduce errors from miscommunication or other human factors and save on the development schedule and cost.

  • Recently, green processes that can be directly used in an energy-efficient and electrified society to achieve carbon neutrality are attracting attention. Existing heat and pressure-based desalination technologies that consume tremendous amounts of energy are no exception, and the growth of next-generation electrochemical-based desalination technologies is remarkable. One of the most representative electrochemical desalination technologies is electrochemical ion separation (EIONS) technology, which includes capacitive desalination (CDI) and battery desalination (BD) technology. In the research field of EIONS, various system applications have been developed to improve system performance, such as capacity and cyclability. However, it is very difficult to understand the meaning and novelty of these applications immediately because there are only a few papers that summarize the research background for domestic readers. Therefore, in this review paper, we aim to describe the technological advances and individual characteristics of each system in clear and specific detail about the latest EIONS research. The driving principle, research background, and strengths and weaknesses of each EIONS system are explained in order. In addition, this paper concluded by suggesting the future development and research direction of EIONS. Researchers who are just beginning out in EIONS research can also benefit from this study because it will help them understand the research trend.

  • Background: Dental hygienists emphasize the ethics of healthcare workers. To effectively cope with various ethical conflicts, it is necessary to establish a reasonable ethical value system. Therefore, this study intends to use basic data to develop ethics education programs and ethical value evaluation tools. Methods: We conducted a questionnaire survey targeting dental hygienists between January 1 and 15, 2023. A total of 251 people's responses were analyzed with SPSS Win 25.0, to perform frequency, t-test, one-way ANOVA, and multiple regression analysis. Results: The idealistic propensity (3.82 points) was higher than the relativistic propensity (3.42 points), and the absolutists showed a deontological position in the partnership area and dental hygiene work relationship area(P < 0.001). Regression analysis of factors affecting ethical values revealed that idealism (β=,444, p=0.000), marital status (β=-0.123, P = 0.035), and position (β=-0.154, P = 0.009) were significantly related to ethical propensity. Conclusion: It is necessary to develop an ethics education program that considers the ethical propensity of dental hygienists and establish firm ethical values by implementing situation-oriented ethics education that can respond to many changes and conflicts.

  • Aids to Navigation (AtoN) is an important tool for safe navigation, and the variety of information provided by AtoN is invaluable. The demand for standardized AtoN information for efficient utilization is gradually increasing, and for this purpose, the International Association of Lighthouse Authorities (IALA) has developed S-201, a standard for the management of AtoN information, and recommends its application to member countries. Notably, since Korea defines AtoNs and manages the information according to the Aids to Navigation Act, the need for definition and information management according to the S-201 standard, an international standard, is even greater. Therefore, in this study, according to the recommendation of IALA, we aimed to suggest a way to manage AtoN information by applying the S-201 standard. To this end, after comparing the classification criteria of the AtoN information of the IALA, and that of Korea's classification standards, Korea's AtoN information management plan applying the S-201 standard was presented. The results of this study provide important basic data for managing standardized digital AtoN information that is easy to use worldwide.

  • In the event of a disaster occurring within a building, the prompt and efficient evacuation and rescue of occupants within the building becomes the foremost priority to minimize casualties. For the purpose of such rescue operations, it is essential to ascertain the distribution of individuals within the building. Nevertheless, there is a primary dependence on accounts provided by pertinent individuals like building proprietors or security staff, alongside fundamental data encompassing floor dimensions and maximum capacity. Consequently, accurate determination of the number of occupants within the building holds paramount significance in reducing uncertainties at the site and facilitating effective rescue activities during the golden hour. This research introduces a methodology employing computer vision algorithms to count the number of occupants within distinct building locations based on images captured by installed multiple CCTV cameras. The counting methodology consists of three stages: (1) establishing virtual Lines of Interest (LOI) for each camera to construct a multi-camera network environment, (2) detecting and tracking people within the monitoring area using deep learning, and (3) aggregating counts across the multi-camera network. The proposed methodology was validated through experiments conducted in a five-story building with the average accurary of 89.9% and the average MAE of 0.178 and RMSE of 0.339, and the advantages of using multiple cameras for occupant counting were explained. This paper showed the potential of the proposed methodology for more effective and timely disaster management through common surveillance systems by providing prompt occupancy information.

  • 정보화의 발전에 비례하여 정보보호의 중요성도 높아지고 있다. 최근까지 정보보호에 대한 관심과 주요 연구의 흐름은 기술적인 보호조치(예: 암호화, 접근제어, 방화벽 등)와 관리적 관점의 행동연구였다. 최근에 들어서야 국내외적으로 정보보호 투자효과에 대한 연구가 활성화되기 시작했다. 정보보호 투자효과에 대한 계량적 산정이 필요한 이유는 정보보호의 중요성을 정확하게 인식할 수 있어 적정규모의 예산을 책정하고 효율적으로 예산을 투입할 수 있는 기초를 마련할 수 있기 때문이다. 정보보호 투자효과를 측정하기 위한 선행연구로 보안사고의 피해규모를 산정하는 연구가 필수적이다. 보안사고의 피해규모는 가시적 손실(피해복구, 생산성 저하, 손해배상 등)과, 비가시적 손실(고객 충성도 저하, 회사의 브랜드 이미지 하락 등) 규모의 합으로 구성된다. 그 동안 가시적 손실규모 측정에 관한 연구는 상대적으로 많았으나, 비가시적 손실규모 측정에 관한 연구는 상대적으로 미흡하였던 것이 사실이다. 이는 현실적으로 비가시적 손실규모를 측정할 수 있는 접근방법을 고안해내는 것이 어려웠기 때문이다. 이로 인해 막연히 비가시적 손실규모가 가시적 손실규모에 비해 대단히 클 것이라고 짐작해 올 수 밖에 없었다. 본 논문에서는 보안사고의 비가시적 손실규모를 측정하기 위해 대규모 개인정보 보안 사고가 발생한 기업의 매출액 증가율을 경쟁기업과 분석하는 연구방법을 제안한다. 매출액은 영업이익 및 순이익과는 달리 회사 내부적인 회계방침에 의해 규모의 조절이 불가능한 재무요소이면서 회사가 고객 충성도 저하와 회사의 브랜드 이미지 하락으로 인해 받게 되는 영향을 가장 정확하게 반영하는 재무요소이기도 하다. 연구방법에 따라 2008년 대규모 개인정보 보안사고가 발생한 국내기업을 선정하고 그 경쟁사와 매출액 변화추이를 비교 분석하였다. 분석결과 보안사고가 발생한 기업의 평균 매출액 증가율이 경쟁사 평균 매출액 증가율 보다 0.0225% 높다는 사실을 발견했다. 이 결과는 국내의 보안 사고가 기업 가치에 미치는 비가시적 영향이 거의 없거나 또는 발생하더라도 그 영향력이 미미하여 가격정책 및 광고 홍보를 통해 충분히 극복할 수 있다는 점을 대변한다. 본 논문의 결과는 역설적으로 국내 보안사고의 피해규모를 측정하는데 있어 가시적 손실규모의 정확한 측정이 무엇보다 중요함을 의미한다.
