This study went beyond making an indicator simply based on theoretical arguments, and explored a wide spectrum of different types of perceptions about energy safety to make a concept of energy safety for the Korean society. The energy safety schemata of people can be divided into three types. Type1 is concern about multi-level risks-responsibility-centric, type2 is concern about security and personal burden-expertise-centric, and type3 is concern about health and personal burden-responsibility-centric. Questions were designed on the basis of the characteristics, differences and commonalities of the three types of perceptions, explored through the Q methodology, and Koreans' perception of nuclear safety was examined. Based on the results of this research the following components of trust in nuclear safety were derived, risk perception, responsibility, honesty, expertise and procedural justification. The items for specifically evaluating them were developed, and factor analysis was conducted, and as a result, the validity of each item was proven. The components of the nuclear safety trust indicator do not exist independently, but influence each other continuously through interactions. For this reason, rather than focusing on any one of them, laws and systems must be improved first so that they can move together in one big frame.

In the field of artificial intelligence education, discussions on the direction of artificial intelligence education are actively underway, and it is necessary to establish a foundation for future information education. It is necessary to design a creative convergence teaching-learning and evaluation method. Although AI experience coding education has been applied, the evaluation stage is insufficient. In this paper, we propose an evaluation system that can verify the validity of the proposed education model to find a way to supplement the existing learning module. The core components of this proposed system are Assessment-Factor, Self-Diagnosis, Item Bank, and Evaluation Result modules, which are designed to enable system access according to the roles of administrator, instructors and learners. This system enables individualized learning through online and offline connection.

Current studies validate the Body Positive Scale (BP Scale) as a self-assessment instrument that captures four dimensions of the positive body image construct. We developed and evaluated a 17-item BP Scale using two focus group interviews and four independent samples (n = 1,379) of Korean women who completed online survey questionnaires. We generated an initial pool of items via literature review, content validation with experts, and focus group interviews, subsequently refining the items through exploratory analysis (Study 1). We confirmed the BP Scale's underlying dimensions with young Korean female samples (Study 2, Study 4) and with a community sample (Study 3). We also examined the construct validity, internal consistency, and test-retest reliability over a six-week interval. Overall, the results supported that the four-factor BP Scale demonstrates adequate validity and reliability in measuring positive body image among Korean women. The BP Scale provides a method for researchers and practitioners to understand and assess individuals' positive body image in a multifaceted manner.

Both the importance and process of estimating Nuclear-power plant construction time and cost have increased in significance as energy user costs themselves have become more significant. In estimating construction time, few parameters are more significant than work item production rates and factors significantly affecting the rates. A standardized data collection tool was used to acquire a total of 401 data points from a S Nuclear-power plant project, for selected critical works: form-work, rebar-work, and concrete-pouring. With the data, several hypothesized drivers of the man-hour production rates and crew-day production rates were also analyzed. Findings from this study will enable industry professionals to enhance accuracy of time and cost estimation for nuclear power plant construction.

This paper explores the impact of mobile device usage frequency in the classroom on students' perceptions of their use. To assess this, we created a survey that measured students' perceived frequency, usefulness, and convenience of using mobile devices, using a reversed Technology Acceptance Model. Through the analysis of responses from 781 Korean students, utilizing confirmatory item factor analyses and a structural equation mixture model, we found that the effect of frequent mobile device use on students' positive perceptions is non-linear. As the frequency reaches to a certain level, the effect sizes of the frequency in the positive perceptions diminishes. Additionally, students who used mobile devices less frequently in class reported higher levels of difficulties in using the devices. This study introduces a tool for evaluating multiple aspects of students' perceptions regarding mobile device use and offers a framework for understanding the relationship between usage frequency, usefulness, and convenience.

운전자는 다양한 종류의 교통정보를 여러 방식을 통해 받을 수 있지만, 인적요소를 고려한 정보 서비스는 이루어지지 않고 있다. 본 연구는 운전자 인적요소에 대한 기초 연구를 실행하기 위해 고속국도 주행 시 다양한 주행환경에서 속도의 차이에 따른 운전자 평균 주시시간의 특성 분석을 목표로 하였다. 분석 시 속도 외에 영향을 줄 수 있는 변수를 통제하기 위하여 주행상황을 '주간에 선행 차량 없이 주행', '주간에 선행 차량이 존재하는 상황에서 주행', '야간에 선행 차량 없이 주행', '야간에 선행 차량이 존재하는 상황에서 주행' 4가지로 분류하였다. ANOVA Test를 활용하여 속도 그룹을 나누었으며 그룹별 평균 주시시간의 차이를 비교하기 위해 다중비교(multiple comparison)를 한 결과 도로, 선행 차량 항목은 속도가 증가함에 따라 평균 주시시간이 증가하고 전경 항목은 평균 주시시간이 감소하는 것으로 나타났다. 도로표지 항목은 속도에 따라 주시시간의 차이가 통계적으로 무의미한 것을 확인할 수 있었다.

This research was conducted to provide basic data for the formulation of marketing strategies suitable to the increasingly globalizing clothing market for the elderly in the fashion industry, by comparing the clothing behavior and preferences of elderly women aged over 70 years in Korea with those of women in the U.S. The 106 questionnaire responses that were collected in the U.S. and the 235 responses that were collected in Korea were used for the analysis, The major objectives of this study were as follow; 1. It was found that the elderly women of Korea utilize mostly human information as information source when purchasing clothing, whereas women of U.S. utilize mostly media information. Comfort was found to be most important factor both countries, but the Korean women considered the aesthetic aspect of clothing more important than did American women. 2. The clothing preference of Korean elderly women aged over 70 years was concentrated in young and feminine images regardless of items, so it could be seen that they had strong desire for looking young. But American elderly women showed different preference depending on items, so it could be seen that they pursue diverse images depending on clothing items and personality without concentrating in one image. The comparison of the preference style by item of elderly women over 70 years of age between Korea and the U,S. showed significant difference. Accordingly, the designs of the clothes of the Korean and American women should be differentiated and developed according to the clothes item and country.
