  • This study was designed to identify and compare the consumption value and interest in appearance with regard to the comparison of men's cosmetics purchase decision factors. We conducted a survey among 259 men who have experienced the re-purchase of men's cosmetics. All data was analyzed with the SPSS Windows 17.0 program in terms of frequency, percentage, means, standard deviations, paired-t test, Cronbach $\alpha$, factor analyses, and multiple regression. In summary, three findings emerged from this study. First, men's cosmetics purchase decision factors included two subfactors: product quality factors (price, quality, skin compatibility, fragrance) and image factors (trend, brand image, consciousness of others, diversion). Second, a paired-t test revealed that the consideration toward the image factors of a first time purchase decision was lower than the re-purchase decision factors. However the consideration toward the product quality factors of a first time purchase decision was not different from the re-purchase decision factors. Third, the product quality factors were positively influenced by distinction factors of appearance and functional value. And social value, emotional value, and curiosity value were found to be effective in the image factors at the first time of purchase and re-purchase. Also, the product quality factors of re-purchase decisions were influenced by the satisfaction of the first time purchase. This study will contribute to provide some information for marketers in understanding men's cosmetics purchase decisions and to offer basic data for marketing strategies and product development.

  • This paper uses 135 Licensed Operator Event Reports (LOER) from Chinese nuclear plants to analyze how safety culture affects unsafe behaviors in nuclear power plants. On the basis of a modified human factors analysis and classification system (HFACS) framework, structural equation model (SEM) is used to explore the relationship between latent variables at various levels. Correlation tests such as chi-square test are used to analyze the path from safety culture to unsafe behaviors. The role of latent error is clarified. The results show that the ratio of latent errors to active errors is 3.4:1. The key path linking safety culture weaknesses to unsafe behaviors is Organizational Processes → Inadequate Supervision → Physical/Technical Environment → Skill-based Errors. The most influential factors on the latent variables at each level in the HFACS framework are Organizational Processes, Inadequate Supervision, Physical Environment, and Skill-based Errors.

  • Demographics, personality traits and attitudes are related to safety behaviors in varied workplaces, but their roles in nuclear power plants (NPPs) have not been fully understood. This study was conducted to explore the roles of a set of demographic, personality and attitudinal factors on self-reported safety behaviors (including safety participation and human errors) among NPP commissioning workers. Survey data were collected from 157 Chinese commissioning workers. Results showed that age and work experience were significantly associated with human errors, but not with safety participation. Neuroticism and conscientiousness were significantly related to human errors, while neuroticism, conscientiousness and agreeableness were significantly related to safety participation. Attitude towards questioning was observed as an antecedent of safety participation, and functioned as a mediating variable in the relation between conscientiousness and safety behaviors. The findings provide evidence-based implications on the design of diverse interventions and strategies for the promotion of safety behaviors in NPPs.

  • 건설 사고재해의 가장 큰 원인은 인적요인이므로, 건설공사에서 휴먼에러를 감소시켜 사고재해를 감소시키는 것이 중요하다. 그러나, 휴먼에러는 조직적 상황의 연속적인 흐름이 배후 요인으로 작용한다. 따라서, 휴먼에러의 배후 요인을 파악할 수 있는 m-SHEL 모델을 사용하여 건설 중대 사고재해를 분석하였다. 분석 결과, 건설 중대 사고재해 유형에 따라 휴먼에러를 일으키는 배후 세부 요인이 차이가 있다는 것을 파악하였으며, 휴먼에러 배후 요인 중 L-m 요인, L-H 요인, L 요인 순으로 많이 차지하고 있는 것을 알 수 있었다. 본연구는 건설공사에서 휴먼에러를 줄이기 위해서는 조직적 상황을 파악하고 대응하는 것이 중요하다는 것을 사례를 통해서 확인하였다는 점에 의의가 있다.

  • Human factors engineering design guidelines for main control rooms(MCR) in nuclear power plants(NPP) have been applied to optimize human-machine interface(HMI) between operators and their equipment on the basis of physical, physiological and cognitive aspects. However, the HMI design for MCR is not found to be sufficient to maximize operators' performance since the operators in the MCR experience excessive stress due to the environmental factors such as inappropriate interiors and illumination. Therefore, well-designed environment of the MCR may be equally important to improve human performance in the MCR. The objectives of the study are two-fold: (1) to propose an interior design of SHIN-KORI 1 2 for pleasant and comfortable working environments, and (2) to design indirect lighting system to enhance visibility and productivity. The human factors engineering checklists were developed to examine whether or not the proposed human-environment design for SHIN-KORI 1 2 satisfies the regulations and guidelines presented by NUREG-0700 Revision 1. The implications of the human-environment design are discussed in detail.

  • BACKGROUND/OBJECTIVES: Average intake of calcium among college students is below the recommended intake, and knowledge surrounding the attitudinal and behavioral factors that influence milk and dairy intake, a primary food source of calcium, is limited. The purpose of this study was to evaluate college students' attitudes and behaviors concerning milk and dairy consumption and their association with calcium intake. SUBJECTS/METHODS: Participants were 1,730 undergraduate students who completed an online survey (SurveyMonkey) as part of baseline data collection for a social marketing dairy campaign. The online survey assessed attitudes and behaviors concerning milk and dairy intake, and calcium intake. Questions about milk- and dairy-related attitudes and behaviors were grouped into 14 factors using factor analysis. Predictors of calcium intake were then evaluated. RESULTS: Median calcium intake across all participants was 928.6 mg/day, with males consuming higher calcium intakes than females (P < 0.001). Adjusted for gender, calcium intakes were most strongly (and positively) correlated with associating milk with specific eating occasions and availability (i.e., storing calcium-rich foods in one's dorm or apartment) (both P < 0.001). Other correlates of calcium intake included: positive-viewing milk as healthy (P = 0.039), having family members who drink milk) (P = 0.039), and taking calcium supplements (P = 0.056); and negative-parent rules concerning milk (P = 0.031) and viewing milk in dining halls negatively (P = 0.05). CONCLUSIONS: Calcium intakes among college students enrolled in the current study was below the recommended dietary allowance of 1,000 mg/day, reinforcing the need for dietary interventions in this target population, especially females. Practitioners and researchers should consider the factors found here to impact calcium intake, particularly associating milk with specific eating occasions (e.g., milk with breakfast) and having calcium-rich foods available in the dorm room or apartment, as intervention strategies in future efforts aimed at promoting milk and dairy foods and beverages for improved calcium intake in college students.

  • Human reliability attempts to make precise quantitative analyses and predictions of the performance of human-machine(or product) systems. In order to yield more precise human error analysis, precise human error probabilities(HEPs) must be used in the analysis. However, because human behavior is influenced by factors that are called performance shaping factors(PSFs), the effects of PSFs must be considered to obtain precise HEPs, These are called basic HEPs or situation-specific HEPs. This paper presents a theoretical method for obtaining basic HEPs (i.e. , considering PSFs) in quantitative human error analysis. In this method, the weight which characterizes the degree of importance of several PSFs is obtained by the analytic hierarchy process. The quality scores of PSFs in the task situation are obtained by percentile concept. These scores are used in conjunction with the relative Importance weights of PSFs to compute the composite quality percentile score of PSFs in the task situation. Then, a new mapping method of the composite quality percentile score of PSFs into a situation-specific basic HEP is proposed with a numerical example.

  • 국외에서는 대형시스템을 사용하는 항공, 해양, 원자력, 철도 등에서 발생하는 사고 중 인적오류가 포함된 사고에 대한 분석 및 연구가 활발히 진행되고 있다. 우리나라에서는 영국, 미국 등의 철도선진국과 비교하여 인적오류를 고려한 철도시스템의 체계적인 운영이 미흡하며, 관련 기준을 별도로 규명하지 않고 있는 실정이다. 또한, 사고 분석을 위한 방법이나 절차, 인적오류와 관련된 원인요소에 대한 항목이 제한적이어서 사고분석이 어려운 실정이다. 이에 본 연구에서는 철도사고구분에 따른 위험사건들을 체계화하여 기관사, 사령, 역무원을 포함한 철도안전업무종사자의 수행도에 영향을 끼칠 수 있는 인적오류원인들을 국내외 연구결과를 바탕으로 체계화하고, 국내 철도 사고 사례를 통해 적합한 인적오류원인을 도출할 수 있는 분류방안을 마련한다.

  • Mammography utilization is low in Iran compared with other countries. Here a cross-sectional survey design was used to investigate psycho-social and individual factors associated with mammography among 400 women asymptomatic of breast cancer. The study was carried out at the four outpatient clinics of Tehran during the period from July through October, 2009. We found that mammography screening was related to higher self-efficacy and women's occupation. Future tailored interventions on potential psycho-social determinants and specific demographic factors are critical in increasing mammography screening rates among Iranian women.

  • Objective: The purpose of this paper is to introduce a task complexity model combining task design aspects and complexity dimensions and to explain an approach to identifying and organizing task complexity factors based on the model. Background: Task complexity is a critical concept in describing and predicting human performance in complex systems such as nuclear power plants(NPPs). In order to understand the nature of task complexity, task complexity factors need to be identified and organized in a systematic manner. Although several methods have been suggested for identifying and organizing task complexity factors, it is rare to find an analytical approach based on a theoretically sound model. Method: This study regarded a task as a system to be designed. Three levels of design ion, which are functional, behavioral, and structural level of a task, characterize the design aspects of a task. The behavioral aspect is further classified into five cognitive processing activity types(information collection, information analysis, decision and action selection, action implementation, and action feedback). The complexity dimensions describe a task complexity from different perspectives that are size, variety, and order/organization. Combining the design aspects and complexity dimensions of a task, we developed a model from which meaningful task complexity factors can be identified and organized in an analytic way. Results: A model consisting of two facets, each of which is respectively concerned with design aspects and complexity dimensions, were proposed. Additionally, twenty-one task complexity factors were identified and organized based on the model. Conclusion: The model and approach introduced in this paper can be effectively used for examining human performance and human-system interface design issues in NPPs. Application: The model and approach introduced in this paper could be used for several human factors problems, including task allocation and design of information aiding, in NPPs and extended to other types of complex systems such as air traffic control systems as well.
