Reflecting the current international trends toward proactive risk assessment and control at work with practical procedures, participatory action-oriented approaches are gaining importance in various sectors. The roles of these approaches in promoting the safety and health at work are discussed based on their recent experiences in preventing work-related risks and improving the quality of work life, particularly in small-scale workplaces. The emphasis placed on the primary prevention at the initiative of workers and managers is commonly notable. Participatory steps, built on local good practices, can lead to many workplace improvements when the focus is on locally feasible low-cost options in multiple aspects. The design and use of locally adjusted action toolkits play a key role in facilitating these improvements in each local situation. The effectiveness of participatory approaches relying on these toolkits is demonstrated by their spread to many sectors and by various intervention studies. In the local context, networks of trainers are essential in sustaining the improvement activities. With the adequate support of networks of trainers trained in the use of these toolkits, participatory approaches will continue to be the key factor for proactive risk management in various work settings.

The antimicrobial activity of the ethanol extract of Hibiscus sabdariffa L. (Roselle) powder against various food-borne pathogens was tested using the lawn diffusion assay. The results showed that the ethanol extract exhibited antimicrobial activities against Staphylococcus aureus (total inhibition), Salmonella enteritidis (partial inhibition), Listeria monocytogenes (partial inhibition), Escherichia coli (partial inhibition), Cronobacter sakazakii (partial inhibition), and Bacillus cereus (partial inhibition). Therefore, it is strongly recommended that Hibiscus sabdariffa L. (Roselle) should be considered for use as a natural food-grade additive for the inhibition of various food-borne pathogens, including both gram-positive and gram-negative pathogens, and the improvement of the overall quality of various dairy products, including milk.

It has been suggested that merging plays an important role in the formation and the evolution of early-type galaxies. Optical-NIR color gradients of early-type galaxies in high density environments are found to be less steep than those in low density environment, hinting frequent merger activities in early-type galaxies in high density environment. In order to confirm if the flat color gradient is the result of dry merger, we decided to look deeply to find merging features and get their relation with color gradient. We selected samples which show extreme values of optical-NIR color gradients based on the data of previous study, and observed them at Maidanak observatory 1.5m telescope with long exposure. After masking out overlaid sources, our analysis reveals that these galaxies do not have extreme color gradient values. High degree sky flat technique was used during observation to aid discovery of faint, extended features. However, flatness of detector (SNUCAM) was good enough, so we could not see any marked improvement in image quality compared to those using normal sky flats. Additionally we noticed a feature that looks like merging tidal tail in the CFHT archival image, but this does not show up on the image we obtained. This demonstrates that flatness and correct sky estimation is very important when we look for faint merging features. In future we plan to enlarge the number of the sample.

The first objective of this study is to investigate and analyze the construction of TUTU and secondly, to propose a systematic research background on a sewing method of TUTU. The final objective is to provide the exquisiteness and the comfort for customer when wearing a stage costume. The research method to investigate the TUTU construction in detail is by renting or buying three major TUTU brands, which are selling in Korea. The results of this study can be summarized into four categories. Firstly, the Bustier composes into 8 to10 patches, and the external material or accessory differs by the work of art and its characteristics. Moreover, the cotton is used for the inner material. which depends on dancer's vital activities. Secondly, a skirt layer ranges from 6 to 12 layers with laces. In addition, the gather or the pleats is used to form a crease. Thirdly, lace or cotton is the material used for culottes because it is stretchy and lightweight. For the waist part. a rubber band is used since its wearability plus functionality. Lastly, an adjusting part for a stage costume varied for each dressers physical feature and can be corrected with inner hems together a hook, a thread loop or a zip. In conclusion, the results of this study can provide the quality improvement for TUTU and furthermore can propose a framework for an understanding and a practical use of TUTU construction.

It is a trend to pursue the reinforcement of child-centered, play-oriented ecological education programs that support children's development. Most of these nature friendly and eco education is done in the outdoor space. So outdoor activities in child care facilities are essential. The purpose of this study was to analyze the actual condition of the outdoor space for ecological child education in the child care center. Therefore, in order to provide the basic data for the direction of the improvement and to grasp the current situation and problems, the survey and analysis of the external space composition and utilization status in the child care facilities for nature-friendly ecological child care education has been done. As a result, the half of the cases did not reserve even the minimum size of outdoor space and fall short of the standards of outdoor space quality as accessibility, complexity, articulation and nature friendliness for ecological education. Therefore, in order to establish an ecological education environment, it is necessary to build facilities in natural green or suburban areas. In addition, they need to use the natural environment such as parks, open spaces, and forests.
