  • Measuring the food safety has been focused only on the psychological consumers' recognition of food safety. The actual measurement tool should consist of the evidence-based statistical data to assess the level of national food safety in scientific perspectives. This paper described the development of a concept to measure the food safety of the food chain based on OECD PSR framework. This paper discusses the elaboration of a set of 8 food safety related data issued as statistical data, and which were same weighted. These food safety statistical data (FSDs) were derived as the basis of measuring the variation of food safety during 2013-2019. The values of the primary production indicator (PPI), the processing and manufacturing indicator (PMI), and the distribution and consumption indicator (DCI) are 0.558-0.859, 0.533-0.691, and 0.979-0.982, respectively. The food safety status (FSS) derived from the safety indicator values of each of the three stages is 0.700-0.810. In order to increase the level of food safety, it is necessary to pay attention to PMI and PPI management. In the future, continuously calculating the level of food safety, managing it like the level of psychological safety, and further expanding it to the level of food safety between countries will help establish policies to improve the level of food safety in Korea.

  • Control Rod Position Indicator in nuclear reactor vessel has developed for small reactor in Korea. Because of severe environment in reactor vessel, target of this study is to develop the suitable position indicator. In this study, solenoid type position indicator made of Mineral Insulated Cable(MI Cable) was introduced to adapt in severe environment. And inductance of the solenoid was used to indicate the rod position for high precision. But problem of this concept is that a linear slope of inductance is changed by temperature effect. To resolve this problem, two sensing coils were introduced for temperature compensation. A role of the sensing coil is to make reference linear equation about certain temperature. To confirm this concept, also, inductance of solenoid and sensing coils were measured at room and high temperature (${\sim}300^{\circ}C$). The results of measurement show that the position error of sensing coil between room and high temperature was about 2%. But it was identified that this error was resulted from insufficient test environment (temperature error between solenoid and sensing coils was about 2% at high temperature condition). Therefore, solenoid type position indicator shows that it is very suitable in reactor vessel as a high precision rod position indicator.

  • Purpose: Although there is a lot of secondary data available for comparing community health status and planning health policies in terms of large area such as metropolitan cities or provinces, there is restricted data for establishing community health policies of the small areas such as towns, Gun(i.e., districts), and Gu. Specifically, the problems of producing a valuable index for health promotion in small areas are three fold: First, there is not an appropriate index model for measuring a small community health status. Second, a large part of secondary data in the small areas has been produced in an irregular time interval. In addition, all valuable data can not be integrated without time consuming work. Thus this study tries to establish a health promotion index model for assisting community health promotion initiatives of local governments. Methods and materials: Literature review, community health specialist consultation and a questionnaire survey was performed. Results: Based on Dever's model, a prototype of health promotion indicators was proposed and modified by the community health specialists. 15 classification scheme of statistical yearbook reorganized into the six areas. Those six areas were comprised in 24 indicator class with 96 specific indicators. Through further modification processes by a questionnaire survey, we developed a health promotion indicator model that contains six areas with 23 indicator class encompassed by 87 specific indicators. Conclusions: This study proposed a model of health promotion indicator comprised in the six areas with 23 indicator classes for measuring small area health promotion status. However, more specific or additional data in human biology, environment, and socioeconomic data is essential for producing a stronger model for health promotion measurement.

  • Objective: The objective of this research is to study preceding literature on safety culture surveying tools and indicators used in aviation organizations to help the further understanding of aviation safety culture by presenting Korea-Safety Culture Survey Indicator (K-SCSI) as a relevant case. Background: The aviation field puts a great deal of effort in preventive safety management through the application of Safety Management System (SMS), which was co-developed by international aviation organizations such as ICAO and FAA. To successfully operate safety management system, safety culture factors such as the organization member's level of consciousness, attitude and faith regarding safety must be put together. However, the aviation field currently lacks programs to promote safety culture and the exact understanding of some safety culture concepts. Method: This research inquired into the definition of safety culture in the aviation field and the surveying tools used to measure it. It then described the development and application process of the Korea-Safety Culture Survey Indicator (K-SCSI) mainly focusing on case studies. Results: In this research are presented safety culture promoting programs that can be applied to subordinate indicators of K-SCSI such as organization commitment, management involvement, rationality of reward system, employee empowerment and reporting system. Conclusion: For a mature safety culture to settle successfully, it is essential that safety culture survey indicators are developed and applied in a way that fits the organization's features. Also, behavior measuring indicators are required to develop a more objective indicator and thus must be standardized. Application: Cases that deal with the development and application of safety culture measuring tools within the aviation field can be studied and applied in other domains to spread safety culture.

  • Most existing damage detection methods based on curvature should investigate the indicator value changes between the intact and damaged state. However, the 'footprint' in the intact state is usually not available for most actual beams. Therefore, a new damage localization indicator called Difference of Nearby Difference Curvature Indicator (DNDCI) was introduced for single-span beams. This indicator does not require prior information of the intact beam and is sensitive to the damage occurs on or nearby the measuring points. Practical and detailed application method of DNDCI has been proposed. Besides the idealized simply supported beams, it was validated by example that DNDCI is also applicable to the actual single-span beams supported by bearings.

  • In order to evaluate the exact effect of detergency it is necessary both to measure the actual soil content by chemical analysis and to determine the degree of soil removal visually. Since it takes considerable time and effort to use both methods, usually one of the two methods is used. Many studies have been carried out through increasing the visibility of oily soil to evaluate detergency by measuring reflectance of fabrics. In this study Sudan Black B, an oil soluble dye was used as an indicator to increase the visibility of oily soil on cotton and polyester fabrics. The condition of artificially soiled fabrics and the method of evaluating detergency were investigated which represent the actual detergency of oily soil by measuring the reflectance only. Also the detergency of Sudan Black B and that of oily soil were compared with each other under various washing conditions, As a result, the K/S values converted from the reflectances showed a good correlation with the actual soil content. Linear relationship between K/S value and the actual soil content was obtained. The K/S values of washed fabrics were higher than those of unwashed fabrics which included same content of soil since the soil visibility changed during washing. But the difference was small when Sudan Black B was used. With the increase of soil content, detergency of cotton fabric decreased, but detergency of polyester fabric increased gradually. With regards to soiled fabrics, detergency of cotton fabric measured by K/S value was close to that of actual oily soil when Sudan black B was used as an indicator.

  • 수도권 내 화학공장에서 부식성 유체를 펌프로 저장탱크에 공급하던 도중 수위파악이 정확히 되지 않아 상부 배기벤트로 부식성유체가 누출되는 사고가 발생하였다. 누출 사고가 발생한데는 다양한 원인이 있지만 직접 원인인 레벨게이지의 수위 지시계가 고착되는 것에 초점을 맞추었다. 분석 결과 사고가 발생한 사업장에서 사용되는 수위 지시계를 임의로 교체하였으며, 사고발생인 여름에 Tubular 방식의 레벨게이지는 열팽창이 쉽게 일어나서 다른 형태보다 고착이 발생될 수 있는 것으로 파악되었다. 또한 국내에는 저장탱크에 설치되는 계측기기의 설치기준이 명확치 않아 적정설치 검토에 어려움이 있었다. 따라서 본 연구에서는 사고사례 및 해외기준을 바탕으로 저장탱크 계측기기류 설치 시 유의사항에 대해 검토하였다.
