Purpose: Smart Safety Living Lab is a Living Lab facility, constructed and operated by KITECH in Korea, to support the user experience(UX) evaluation, planning and certification of smart safety products and services. The purpose of this study is to develop a UX evaluation methodology that accommodates the characteristics of the Living Lab and smart safety products and services for a systematic and efficient UX evaluation in the Smart Safety Living Lab. Methods: A generic model of UX evaluation was first derived based on a review of related literature. Then, the generic model is revised to accommodate the characteristics of the Smart Safety Living Lab and smart safety products and services, resulting in the UX Evaluation Methodology for Smart Safety Living Lab (SSLL-UXEM). Results: The developed SSLL-UXEM consists of a structured process for UX evaluation, a guideline for conducting each step of the process, and a set of forms for recording the major evaluation results in each step. Conclusion: SSLL-UXEM can help to enhance the efficiency of the UX evaluation process and the consistency of the UX evaluation results. SSLL-UXEM is also expected to serve as a basis for UX evaluation in various living lab environments in the future.

The purposes of this study were to assess the child care centers' foodservice facility, and to develop the kitchen facility model based on the general sanitation standards and guidelines in order to provide basic information for a plan review to build or renovate child care centers' foodservice facility. The scopes of the study include : 1) field assessment of the foodservice management practices and facilities in 8 public child care centers, and 2 private child care centers which they are subsidized from the government as public child care centers, 2) development of child care centers' kitchen facility model based on the General Sanitation Standards and Guidelines. The results of this study can be summarized as follows : 1. Field Assessment of the Child Care Centers' Foodservice Facility Average number of children in child care centers was 78.0$\pm$24.20, the average space of kitchen was 15.13$\pm$4.25($m^2$). Especially, the average space of kitchen was 18.49$\pm$4.35($m^2$) with enrollment capacity of 90～120 children in child care centers. The inventory level of most foods was relatively low except rice and kimchi. Kitchen facilities and equipments were similar to those of home kitchen and did not meet the standards of institutional practice. Therefore, the director in child care centers should recognize the importance of the sanitation management and pay more attention to the renovation of foodservice facilities as well as sanitation management practices. 2. Development of the Kitchen Facility Model based on the General Sanitation Standards and Guidelines The kitchen facility plan model with enrollment capacity of 100 children was developed based on the results of field assessment and literature review. Suggested kitchen space was 34.16$m^2$(6,100mm×5,600mm). This space was bigger than the results of field survey or precedent study, considered appropriate to implement the general sanitation standards. The main feature of the developed kitchen facility plan and model was product flow in one direction from the arrival of the raw material to the finished product in order to prevent cross contamination and to improve working efficiency.

중 저준위 방사성폐기물 처분시설의 운영 중 사고로 인한 방사선적 영향을 평가하기 위해서는 운영 중 발생 가능한 사고에 대한 타당성이 입증되어야 한다. 본 논문에서는 처분시설의 운영 중 사고분석 체계를 처분시설의 구성요소에 대한 안전기능분석, 잠재위험요소분석, 위험도분석, 그리고 향후 조치대안으로 사고평가체계를 개선하였다. 이를 위하여 위험도분석에 필요한 설계대안과 관리대안을 추가하여 설계-운영-평가가 연계되도록 하였다. 또한 운영 중 사고의 발생확률과 평가결과의 심각성에 따라 운영중 사고에 대한 분류기준을 제안하여 처분시설 운영 중 대표 사고시나리오에 대한 정당성을 확보하였다. 본 논문의 개선된 평가체계를 우리나라의 2단계 중 저준위 방사성폐기물 표층처분시설에 대한 처분시설 운영 중 사고분석의 사례에 대해 적용하였다.

Infrastructures in Japan constructed mostly in high economic growth period become elder & elder, and the troubles & accidents caused by the aging increase. Though investment for the renewal is necessary, the shortage of public fund delays the action. Besides, we expect the decrease of the population that means the decrease of the engineers who take care of social infrastructures. Thus, it is necessary for us to develop Advanced Management system of social Infrastructures (AMI) to realize the efficient and economical operation. Our concept of AMI consists of using ICT, PI (Public Involvement) and establishment of O&M diagnosis system. We expect AMI will support to realize the appropriate repairing, preventive maintenance based on the actual performance, accidents & dangerous experience and education & training of the workers. In this paper, development of AMI for the waste disposal facility as a first example of infrastructures will be shown.

This study analyzed how the installation of a pressure gauge in the indoor fire hydrant of an apartment building affected identifying pressurized water in the pipe, making it easier to conduct internal inspection on the fire suppression system, and ensuring reliability of fire suppression. The following are the study's results: First, identifying pressurized water in the indoor firefighting pipe had a positive effect on the installation of a pressure gauge in the indoor fire hydrant. This implies that a higher level of identification of pressurized water in the indoor firefighting pipe had a positive impact on improving the installation and use of a pressure gauge in the indoor fire hydrant. Second, making it easier for the fire safety officer to inspect the fire suppression system had a positive effect on the installation of a pressure gauge in the indoor fire hydrant. This suggests that if it becomes easier for the apartment building's stakeholder to conduct internal inspection or the firefighting facility manager to carry out inspection on the fire suppression system, it would have a positive effect on the installation of a pressure gauge in the indoor fire hydrant. Finally, ensuring reliability in fire suppression had a positive effect on the installation of a pressure gauge in the indoor fire hydrant. This implies that if it becomes easier to identify pressurized water in the indoor firefighting pipe, for the fire safety officer to conduct internal inspection, or for the firefighting facility manager to carry out inspection in accordance with the fire suppression system's internal inspection requirements, it would increase reliability in fire suppression, making it more necessary to install a pressure gauge in the indoor fire hydrant.

The purpose of this study is to investigate EU, UK and USA's laws and standards related to safety criteria for commercial kitchen machines. The study was based on literature survey and web surfing. The results revealed that EU has relevant directives by kitchen machines and harmonized standards according to the directives. The directives and harmonized standards are translated into the laws and standards of EU member countries, respectively. The kitchen facility relevant legal systems of UK and USA do not prescribe the safety devices or measures, but only the basic health and safety requirements. The requirements were forcefully implemented through the certificate systems such as CE(Confommite European), UL(Underwriters Laboratories), etc. Only products with CE, UL or NRTL(ationally Recognized Testing Laboratory) certificate marking can be placed on the market of EU and USA, or put into service. For achieving the certificates, all requirements regulated in the relevant standards should be met. The standards of UK and USA were presented by kitchen machines or by standards themselves, respectively. Safety devices required by the standards were also summarized by kitchen machines and their risk factors.
