The common recognition which the organic product is compared as safe to baby does not mean there is especially plentiful nutrition in organic product. The part mineral content of agricultural products follows in soil quality, therefore plentiful chemical fertilizer-use to change soil quality results in the possibility of the mineral content change. The vitamin, carbohydrate, protein and fatty acid composition does not change largely from original nutrition facts. Rather than, the most advantage of organic product is relieving baby from agricultural chemical harms. It will be a strong desire for consumers to eat safe, believable and healthy food like organic foods. Furthermore, it will be sincerely good to environment and ecosystem.

Bridge load rating calculations provide a basis for determining the safe load capacity of bridge. Load rating requires engineering judgement in determining a rating value that is applicable to maintaining the safe use of the bridge and arriving at posting and permit decisions. Load testing is an effective means in calculating the rating value of bridge. In Korea, load carrying capacity of bridge is modified by response modification factor that is determined from comparisons of measured values and analysis results. The response modification factor may be corrupted by vehicle location error that is defined as the gap of test vehicle location between load testing and analysis. In this study, the effects of vehicle location error to structural response and response modification factor are investigated, and a new method for evaluating response modification factor is proposed. The random data analysis shows that the proposed method is less sensitive to vehicle location error than the present method.

Bridge load rating calculations provide a basis for determining the safe load capacity of bridge. Load rating requires engineering judgement in determining a rating value that is applicable to maintaining the safe use of the bridge and arriving at posting and permit decisions. Load testing is an effective means in calculating the rating value of bridge. In Korea, load carrying capacity of bridge is modified by stress modification factor that is determined from comparisons of measured values and analysis results The stress modification factor may be corrupted by vehicle location error that is defined as the gap of test vehicle location between load testing and analysis. In this study, the effects of vehicle location error to structural response and stress modification factor are investigated, and a new method for evaluating stress modification factor is proposed. The random data analysis shows that the proposed method is less sensitive to vehicle location error than the present method.

Fail-safe design of machine elements or structural members is very aim of the whole mankind. Fracture occurs generally from cracks that exist originally or produced from flaws. The most important job we have to do is to make stopping or decreasing the crack growth rate. For fail-safe design variable thickness plates have been used as structural members in practical engineering services. In this paper, optimum design of CT type plate with varlng thickness is studied with the theoritical analysis. The theoritical analysis was based on the stress concentration and nominal stress analysis. From the study, the optimum design curve was determined for use of designing of such structures using the computer analysis program of optimum design.

Dexmedetomidine is a potent alpha-2-adrenergic agonist, more selective than clonidine, with widespread actions on the mammalian brain. A large body of recent work supports its analgesia and sympatholytic properties. Dexmedetomidine is a useful medication with many clinical applications. The medication has shown efficacy in decreasing the need for opioids, benzodiazepines, propofol, and other sedative medications. Dexmedetomidine has been used effectively for sedation during invasive procedures and in the ICU. Short-term sedation has been shown to be safe in studies, although hypotension and bradycardia are the most significant side effects. Dexmedetomidine is emerging as an effective therapeutic agent in the management of a wide range of clinical conditions with an efficacious, safe profile.

Purpose: Consumers can experience better service for distribution of products with payment technology such as QRIS (Quick Response Code Indonesian Standard) compared to conventional purchase methods. This research aims to determine the experience of QRIS service users in Indonesia. Perceived Usefulness, Ease of Use, and Perceived Security were independent factors. Behavioral Intention to Use is the dependent variable. Furthermore, Word of Mouth Attitude is an intervening variable. Research Design, Data, and Methodology: Involving active QRIS users in a survey-based quantitative study in Indonesia. A survey sample of 400 people was taken from data records of 30.87 million QRIS users in Indonesia. Data were analyzed using SEM-PLS. Results: Show that Perceived Usefulness and Perceived Ease of Use significantly impact Attitudes Word of Mouth, and Behavioral Intention to Use. This research also found that Behavioral Intention to Use does not significantly impact Perceived Security. Conclusion: QRIS, as a revolutionary innovation, offers faster payments than previous methods, with a payment time of no more than one minute. QRIS is seen as valuable, simple, and safe, disseminating information to the public and continuing to use QRIS. The implications of this research are very significant in accelerating the flow of distribution of goods and services and facilitating transactions.

Bird collisions with glass are a substantial source of human-caused avian mortality. It has been estimated that between 100 million and 1 billion birds die in collisions with windows every year, and bird-window collisions can have a particularly serious impact on populations because glass is dangerous for strong, healthy, breeding adults. The purpose of this study are to address the bird-window collision issue and to provide suggestions for bird-safe development by reviewing precedent studies on bird collision and analyzing bird-friendly design guidelines. Typically reflections of the sky, clouds or trees on glass, green plants in lobbies, and lights attract and confuse both migrating and resident birds. Therefore birds fatally fly into the glass because they do not recognize that reflections are false and that glass is a barrier. Many cities such as Toronto, Chicago and New York have made efforts on reducing the bird collision by encouraging the creation of environmentally conscious and bird-safe buildings. The USGBC also introduced a bird-safety credit as part of its environmental certification process, called LEED. The results of the study presented that architects and builders can help reduce or prevent bird from collisions in both new construction and existing structures with creative use of design elements. The measures to reduce bird collisions include using glass with an embedded pattern, opaque or translucent films, decals, dot patterns, awnings, louvers, and grilles. Turning off lights after midnight during the spring and fall migrations can be part of the solution as well. In order to reduce bird mortality, the most important thing is to generate awareness of the issue among designers, builders, as well as the public. Also local governments need to develop bird-friendly design guidelines and planning mechanisms to encourage bird-safe development and building operation.

Millions people in the US suffer from foodborne illnesses each year. In the US, multiple government agencies work separately or together to ensure the nation's food safety for different audiences. FDA plays a key role in ensuring food safety in foodservice operations by providing the Food Code. School foodservice operations must follow the FDA guidelines on food safety and make sure that foods produced in school foodservice are safe. Despite the continuous efforts, school foodservice operations were responsible for numerous foodborne outbreaks. Currently, school foodservice operations serve younger children (<5 years) and children with medical conditions which make the food safety extremely important. There are many programs that foodservice operators can use to train and educate their employees. ServSafe$\^$ⓡ/tate or local food safety education programs, Serving It Safe, and HACCP workshop are common programs that can be used to train their staff. HACCP is a preventative program that can prevent foodborne illnesses before they occur. Although there are many benefits of utilizing HACCP and training programs, a majority school foodservice directors and managers still did not implement HACCP nor perceived their food safety training is adequate. Most reasons why not implementing HACCP program are lack of trained personnel, time, and financial resources in the school foodservice systems. The gap between what people know and what people do is another challenge identified as an obstacle food safety programs. Despite safe food sources in the US, continuous training is necessary to remove human errors and ensure food safety in the school foodservice systems. Future research is recommended to reduce gap between food safety knowledge and behavior. Foodservice operators and researchers may apply the systems developed in the US to their food systems.
