  • Purpose: The purpose of this study was to develop a scale to evaluate parenting stress of international marriage immigrant women from Vietnam and the Philippines. Methods: The concept of parenting stress of international marriage immigrant women was analysed with a hybrid model. Data were collected from 273 international marriage immigrant women from Vietnam and the Philippines who were raising their children aged 1 to 6 years. These collected data were subjected to exploratory factor analysis, multitrait/multi-item matrix assessment, Pearson correlation coefficient analysis, and Cronbach's alpha internal consistency measurement. Results: The final instrument consisted of 28 items. The following six factors were extracted by exploratory factor analysis: 'insufficiency of parenting support system', 'role burden of mothers', 'maladjustment of children', 'confusion of parenting methods due to cultural differences', 'unskilled Korean communication', and 'ordinary difficulties'. Construct validity (factor analysis, convergent validity, and discriminant validity) and criterion-related validity were confirmed. Cronbach's ${\alpha}$ value of total items was .92(95% CI .91-.94). Cronbach's ${\alpha}$ of values for these factors ranged from .76 to .85. Conclusion: The parenting stress scale for international marriage immigrant women is a valid and reliable tool.

  • The fire and explosion properties necessary for waste, safe storage, transport, process design and operation of handling flammable substances are lower explosion limits(LEL), upper explosion limits(UEL), flash point, AIT( minimum autoignition temperature or spontaneous ignition temperature), fire point etc., An accurate knowledge of the combustion properties is important in developing appropriate prevention and control measures fire and explosion protection in chemical plants. In order to know the accuracy of data in MSDSs(material safety data sheets), the flash point of phenol was measured by Setaflash, Pensky-Martens, Tag, and Cleveland testers. And the AIT of phenol was measured by ASTM 659E apparatus. The explosion limits of phenol was investigated in the reference data. The flash point of phenol by using Setaflash and Pensky-Martens closed-cup testers were experimented at $75^{\circ}C$ and $81^{\circ}C$, respectively. The flash points of phenol by Tag and Cleveland open cup testers were experimented at $82^{\circ}C$ and $89^{\circ}C$, respectively. The AIT of phenol was experimented at $589^{\circ}C$. The LEL and UEL calculated by using Setaflash lower and upper flash point value were calculated as 1.36vol% and 8.67vol%, respectively. By using the relationship between the spontaneous ignition temperature and the ignition delay time proposed, it is possible to predict the ignition delay time at different temperatures in the handling process of phenol.

  • This study measured and analyzed male firefighters hand sizes as well as suggested data for developing firefighting gloves with a good fit. Accordingly, body dimensions related to the hand were measured for 100 male firefighters. Twenty-three measuring items related to the hand and lower arm were selected. The firefighters' measurement data were compared to general adult male measurements from the 6th Korean Anthropometric data to analyze the hand sizes characteristics of firefighters. As a result, height, hand circumference, hand breadth, wrist circumference, elbow-wrist length, forearm-fingertip length and firefighter weight were significantly larger than adult males. A correlation analysis for 23 items was conducted to select items used as standards for setting a size when manufacturing firefighting gloves. Hand length and circumference were selected as representative hand parts for making firefighting gloves. Cross analysis between hand length and circumference were conducted to find the section showing the highest distribution ratio. As a result, the highest sections were between 19cm and 21cm for hand circumference and between 18.5cm and 19.5cm for hand length, which may be suggested as the most important ranges.

  • Various leading indicators of safety culture have been advocated for proactive actions as lagging indicators have limitations in reflecting the attitudes and behaviors due to their reactivity and low sensitivity. This study proposes a model of incident-reporting culture (IRC) and determines the influence of the components on incident-reporting rate (IRR) in order to develop proactive indicators of safety culture. A questionnaire survey was administered to 614 workers at a chemical company in Korea, and the internal psychological aspects were explored by using perceptions, attitude, and backgrounds. The relationship between these factors and IRR was quantitatively confirmed. The workers are more reluctant to report injury than property damage, the perception of severity is the most influencing factor, and most property damages are reported regardless of worker's willingness. These features should be prioritized when improving IRC, and the criteria of IRC need to be aligned with safety culture.

  • Digital Game design with educational purposes and User Experience measurement via game analytics has been extensively covered in literature, however non-digital games such as tabletops in education and its corresponding educational impact have limited research. In this paper, we propose a guideline to create non-digital educational games from scratch and evaluate them based on the know-how of developers and the investigation of scholars who have studied the engagement factors related to the digital games and applied their findings to non-digital games. Along with the guideline we provide an actual implementation, a game called HXGN_766, meant to serve as scaffolding of computational thinking and rudimentary Python programing concepts. We believe both, guideline and game, can be a useful reference for those interested on game design, educational content design, game quality control check, and unplugged computer science activities. This is the first in a series of papers where the game design concept, the evaluation methodology and the game itself will be presented with more detail.

  • 기계학습 기반 비디오 화질 자동 측정 기술은 주관적 화질 평가를 대체하기 위한 기술로, 비디오를 입력 신호로 화질 평가 결과를 출력 신호로 하는 기계학습 모델을 통해서 개발하는 기술이다. 학습에 필요한 비디오 데이터 셋은 입력 신호인 비디오 시퀀스와 입력의 출력신호로 학습할 주관적 화질 평가 결과로 구성된다. 이때 데이터 셋의 일부는 기계학습 기반 비디오 화질 자동 측정 기술 개발 과정에서 학습에 사용하고, 남은 일부는 개발 기술의 성능 평가에 사용한다. 일반적으로 기계학습 기반 기술의 성능은 학습 데이터의 양과 질에 비례한다. 그러나, 기계학습 기반 비디오 화질 자동 측정 기술 개발에 필요한 데이터 셋은 주관적 화질 평가 결과를 포함해야 하므로, 데이터 양을 늘리는 것은 쉬운 문제가 아니다. 이에 본 논문에서는 압축 비디오에 대한 화질 자동 측정 기술 개발을 위해 필요한 데이터 셋을 양과 질적 측면에서 효율적으로 구축하는 방법을 제안한다. 양적 측면에서 효율성을 높이기 위해 부호화 복잡도와 평가 난이도 기반으로 시퀀스를 선정 방법을, 질적 측면에서 효율성을 높이기 위해 쌍 비교(Pairwise Comparison)기반의 주관적 화질 평가 방법을 제안한다.

  • This study aimed to determine the applicability of drones and air quality sensors in environmental monitoring of air pollutant emissions by developing and testing two new methods. The first method used orthoimagery for precise monitoring of pollutant-emitting facilities. The second method used atmospheric sensors for monitoring air pollutants in emissions. Results showed that ground sample distance could be established within 5 cm during the creation of orthoimagery for monitoring emissions, which allowed for detailed examination of facilities with naked eyes. For air quality monitoring, drones were flown on a fixed course and measured the air quality in point units, thus enabling mapping of air quality through spatial analysis. Sensors that could measure various substances were used during this process. Data on particulate matter were compared with data from the National Air Pollution Measurement Network to determine its future potential to leverage. However, technical development and applications for environmental monitoring of pollution-emitting facilities are still in their early stages. They could be limited by meteorological conditions and sensitivity of the sensor technology. This research is expected to provide guidelines for environmental monitoring of pollutant-emitting facilities using drones.

  • The purpose of this study is to develop and validate the disaster safety awareness scale for high school students. For this purpose, the previously developed disaster safety awareness scale and related prior research was analyzed. Questionnaire data was collected from March 22 to May 25, 2021 from 1054 students (male: 569, female: 485) in the first, second, and third grades of 5 high schools in 3 cities. Through the process of revising, supplementing, and reviewing the items extracted through preliminary research and preliminary test together with experts and students, a final disaster safety awareness scale consisting of 24 items was developed. This scale consists of four sub-factors: 'disaster prevention', 'disaster response A', 'disaster response B', and 'disaster recovery'. Good reliability and validity were secured through exploratory and confirmatory analyses. The significance of this study is that it laid a basic and objective foundation for high school students' disaster safety awareness research by developing a validated scale in a situation where the development of disaster safety awareness scales for high school students was still insufficient. It can be used as useful data for fire safety education as well as a psychological measurement tool for fostering fire safety awareness.
