This study analyzed the gender factors and priorities that are on the basis for establishing the school safety education policy according to the times when the demand for customized education is increasing. AHP analysis method was used in the paper for systematic and hierarchical analysis. We had checked a safety education specialist group to identify the priorities of important factors to improve the efficiency of analysis. The male group first considered the change of the beneficiary by policy guidelines, and the female group regarded the change of interest and public opinion as important. This has studied the difference in approach between the two groups, although the key elements of the detailed policy are the same. This study suggests that school safety education is effective in improving effective gender safety education response capacity and ensuring substantive policy sustainability.

Purpose: This research was for understanding the attitudinal difference by gender towards emotional design through questionnaire survey with female and male inpatients on environmental characteristics of wards in general hospitals. Methods: The survey was conducted by questioning inpatients at two general hospitals on the importance rating on emotional design elements of patient rooms, lounges, and hallways. Eighty questionnaires were returned and used for data analyses through SPSS windows version 15.0 statistic package program. Results: 1) In general, female patients considered emotional design of wards as more important than male patients and the most outstanding difference was indicated for patient rooms among patient rooms, lounges, and hallways. For patient rooms the comfortability index was rated as the most important to both female and male inpatient groups, and for lounges and hallways the safety index was evaluated as the most important to both gender groups. 2)For lounges, while male patients rated 'prevention of infection' important among safety relating items, women considered 'accident prevention' more important. It is inferred that female patients have more safety needs and anxiety about physical injury or accidents than male ones do. Implications: It is considered that there need to be further succeeding in-depth studies, e.g. research interviews with inpatient;s family members or other caregivers as well as patients themselves.

DUPIC (Direct use of spent PWR fuel in CANDU reactors) nuclear fuel is a CANDU fuel fabricated remotely from spent PWR fuel materials in a hot cell. The soundness of the end closure welds of nuclear fuel elements is an important factor for the safety and performance of nuclear fuel. To evaluate the soundness of the end closure welds of DUPIC fuel element, a precise X-ray inspection system is developed using a micro-focus X-ray generator with an image intensifier and a real time camera system. The fuel elements made of Zircaloy-4 and stainless steel by an Nd:YAG laser welding and a TIG welding aye inspected by the developed inspection system. The soundness of the welds of the fuel elements was confirmed by the X-ray inspection process, and the irradiation test of DUPIC fuel elements has been successfully completed at the HANARO research reactor.

Purpose: This study was conducted to experimentally investigate the structural safety of and identify critical locations in a front-end loader under impact loads. Methods: Impact and static tests were conducted on a commonly used front-end loader mounted on a tractor. In the impact test, the bucket of the front-end loader with maximum live load was raised to its maximum lift height and was allowed to free fall to a height of 500 mm above the ground where it was stopped abruptly. For the static test, the bucket with maximum live load was raised and held at the maximum lift height, median height, and a height of 500 mm from the ground. Strain gages were attached at twenty-three main locations on the front-end loader, and the maximum stresses and strains were measured during respective impact and static tests. Results: Stresses and strains at the same location on the loader were higher in the impact test than in the static test, for most of measurement locations. This indicated that the front-end loader was put under a severe environment during impact loading. The safety factors for stresses were higher than 1.0 at all locations during impact and static tests. Conclusions: Since the lowest safety factor was higher than 1.0, the front-end loader was considered as structurally safe under impact loads. However, caution must be exercised at the locations having relatively low safety factors because failure may occur at these locations under high impact loads. These important design locations were identified to be the bucket link elements and the connection elements between the tractor frame and front-end loader. A robust design is required for these elements because of their high failure probability caused by excessive impact stress.

Graphite material plays an important role in nuclear reactors especially the high-temperature gas-cooled reactors (HTGRs) by its outstanding comprehensive nuclear properties. The structural integrity of graphite pebble fuel elements is the first barrier to core safety under any circumstances. The correct knowledge of the stiffness coefficient of the graphite pebble fuel element inside the reactor's core is significant to ensure the valid design and inherent safety. In this research, a vertical extrusion device was set up to measure the stiffness coefficient of the graphite pebble fuel element by the Institute of Nuclear and New Energy Technology (INET) of Tsinghua University in China. The stiffness coefficient equations of graphite pebble fuel elements at different temperatures are given (in a helium atmosphere). The result first provides the data on the high-temperature stiffness coefficient of pebbles in helium gas. The result will be helpful for the engineering safety analysis of pebble-bed nuclear reactors.

For last decades, the interests and efforts to enhance healthcare facility users' experience is focused on improving facility environments for healing (Delvin, 2003) and servicescapes in order to meet the users' needs (Becker, 2008; Seunghee, 2011). In the emerging experience economy, customer want experiences and they're willing to pay for the experiences and memories not goods. (Pine, J. & Gillmore, J., 1999). It is important to identify what supports customer experiences and how they perceive the experiences in healthcare environments and it will provide important information for healthcare planners, managers, architects, and interior designers. This study examines the service user experience design elements from a User Experiences design perspective. It focuses on healthcare facilities as user experience elements and build up a conceptual framework that outlines service user experience design elements in healthcare facilities. Literature review and case studies were conducted to build the service user experience design elements according to affordance theory. Findings from this study shows that service user experience design elements were introduced and newly developed which can be categorized into three factors; 1) Functional experiences in the physical environments (safety, accessibility, self-directiveness), 2) emotional expression and cognitive experiences (identifiability/clarity, natural features/pleasant environment, aesthetic elements/playful space, media richness), 3) social relational experiences(closeness, privacy, communication with staff, integrated system). These service user experience design elements will help healthcare facility designers to understand what customer experiences, how they increase the satisfaction, and how they improve facilities for modeling the industry's best practices.
