Purpose: The purpose of this study was to develop a wellness index for workers (WIW) and examine the validity and reliability of the WIW for assessing workers' wellness. Methods: The developmental process for the instrument included construction of a conceptual framework based on a wellness model, generation of initial items, verification of content validity, preliminary study, extraction of final items, and psychometric testing. Content validity was verified by 4 experts from occupational health nursing and wellness disciplines. The construct validity, convergent validity and discriminant validity were examined with confirmatory factor analysis. The reliability was examined with Cronbach's alpha. The participants were 494 workers from two workplaces. Results: Eighteen items were selected for the final scale, and the results of the confirmatory factor analysis supported a five-factor model of wellness with acceptable model fit, and factors named as physical emotional social intellectual occupational wellness. The convergent and discriminant validity were also supported. The Cronbach's alpha coefficient was .91. Conclusion: The results indicate that the WIW is a valid and reliable instrument to comprehensively assess workers' wellness, and to provide basic directions for developing workplace wellness program.

We developed a novel method of fluidic self-assembly to replace the conventional pick-and-place method. This method is cheaper and more effective than the previous method. For this research, we compared mathematical models with experimental results using the parameters of the drag force, the capillary force, and the restoring force for effective chip assembly, and the results for the alignment to the substrate. We obtained a 96.5% attach rate and $5^{\circ}$-misalignment to the substrate in a 500 ${\mu}m$ solder ball.

New concept of wind energy conversion system is proposed to increase the energy density at a given working space. The quality of wind for wind power generation is depend on its direction and speed. However, the quality is not good on land because wind direction is changeable all the time and the speed as well. The most popularly operated wind turbine system is an axial-flow free turbine. But its conversion efficiency is less than 30% and even less than 20% considering the operating time. In this research, a cross-flow type wind turbine system is proposed with a convergent-divergent duct system to accelerate the low speed wind at the inlet of the wind turbine. Inlet guide vane is also introduced to the wind turbine system to have continuous power generation under the change of wind direction. In here, the availability of wind energy generation is evaluated with the change of the size of the inlet guide vane and the optimum geometry of the turbine impeller blade was found for the innovative wind power generation system.

Fashion professionals these days agree that changes in the fashion business are essential and highly value creativity as a genuine source for generating new ideas in fashion products as well as fashion business practices. As fashion professionals deal with problems of which solutions do not exist or that need innovative solutions for brand or product differentiation in the fast-paced environments, interest in creativity and creative problem solving in the field has increased; therefore, fashion educators have realized that there has been an increasing need for incorporating creativity or creative problem solving into the fashion curriculum. In this study, the researcher intended to review previous research on the use of creative problem solving in classrooms in various disciplines including the field of fashion education to provide insights and suggestions for fashion educators to integrate creative problem solving into the fashion education curriculum. Previous attempts to apply creative problem solving to solve issues in fashion classrooms have mostly limited to promoting divergent thinking techniques. It is suggested for fashion educators as well as fashion students to consider creative problem solving as a process consisting of the four distinct stages in which both divergent and convergent thinking techniques should be properly utilized stimulating various thinking strategies.

The dual-throat nozzle is an extremely effective method in the thrust vectoring control field, utilizing another convergent section to connect with the divergent part of the conventional convergent-divergent nozzle. In the present research, the numerical simulation is conducted to investigate the effects of the injection angle on thrust vectoring performance in a 3D supersonic nozzle. Five injection angles are discussed and core performance variations are analyzed, including the deflection angle, injected mass flow ratio, system resultant thrust ratio, efficiency, Mach number contour and streamline on the symmetry plane, and Mach number contours at different slices. Meaningful conclusions are offered for fighter jet designers.

This study is the academic work to explore the potential meanings of print advertisements. Linguistic features such as repetition, variation, contrast and phonological structure in the verbal texts of ads can give rise to shades-of-meaning or slight variations in advertising. The language of advertising is not only language in words. It is also a language in images, colors, and pictures. Pictures and words combine to form the advertisement's visual text.. While the words are very important in delivering the sales message, the visual text cannot be ignored in advertisements. Forming part of the visual text is the paralanguage of the ad. Paralanguage is the meaningful behaviour accompanying language, such as voice quality, gestures, facial expressions and touch in speech, and choice of typeface and letter sizes in writing. Foregrounding is the throwing into relief of the linguistic sign against the background of the norms of ordinary language. This paper focuses its discussion on the advertisements within the framework of the paradigmatic and the syntagmatic relationship. The sources of ads have been confined to Malboro. The ads were reselected based on purposive sampling methods.

This study investigated a utilization deficiency phase in the situation of children's acquiring mnemonic strategies in which children successfully execute a strategy but the strategy does not facilitate memory performance. This study examined spontaneous acquisition of elaboration strategy among 5th grade children in the learning of noun pairs for 5 sessions. Participants were tested in memory task using different list of word pairs in each session. Results showed that children increased the use of elaboration strategy significantly in 5 sessions but they did not gain benefit in recall. When the word pairs were associated, the use of elaboration strategy was significantly increased but children did not gain benefit in recall. This results were discussed in terms of utilization deficiency.

In Europe side, Most of North Korean refugee lives in New Malden, Kingstone resident with South Korean and international student near London, United Kingdom (UK).The reason why dispersed around in Europe is can be issue in societies with secure problem and temporary protection status have to be accept for change the concept in international law and refugee law. their ethnicity is organized by North Korean defectors, South Korean, Korean-Chinese in the area of New Malden and Kingstone.it means small unification is going to foundation on abroad. also their solidarity of diasporic integration development would ahead. and have to organise of Coexistence between U.K and thier ethnicity. for Humanitarian way for vulnerable. But Europe is not the most welcoming place for North Koreans at the moment. The European Alliance for Human Rights in North Korea, an advocacy group, reported in 2015 that many European countries had rejected the vast majority of North Korean asylum cases. Partly this is to do with how governments view North Korean defectors: the UK "considers North Koreans as South Korean citizens, thus excluding them from refugee status".
