Cultural and creative products promote social and economic development. China's traditional art culture is not only indispensable in developing its own cultural and creative products but also one of the important sources of international cultural and creative industries for its design inspiration and material generation and development. It is not only the exchange and common development of Chinese culture and the cultural fields of other countries in the world but also further promotes the response to the policy of "One Road One Road One Road" and "Building a Community with a Future for Humanity." In the field of culture and art in China, the cultural and artistic symbols of Chinese calligraphy are richly reflected in the design. The research method is mainly through a case study, visual analysis, etc., to reflect the value of cultural and artistic symbols contained in Chinese characters in packaging design. The analysis is mainly based on the current situation, problems, and innovative exploration of various elements of Chinese calligraphy and artistic symbols in the packaging of creative products. Because of the design and development of the artistic symbols of Chinese characters, the significance of the research results is not only as a unique cultural heritage of China but also expected to provide a reference for the world's cultural and artistic exchanges, innovative development, and integrated development.

There are many aspects to consider the good assembly model for Thai wooden furniture. The main idea is the assembly can be made in difference ways. As a result, the easy to assemble means the efficiency to produce. The way how to make an assembly need to be considers. The assembly assessment model is evaluated from the assembly’s method, the assembly’s point, the assembly’s direction, the assembly’s difficulty and the assembly’s motion and time. All these assembly criteria needed to be set to make the assembly easier. Also, part’s size and weight and part’s direction can affect the result of the assembly. With these assembly criteria, Thai’s wooden furniture experts are choosing to select sub-criteria and compare all sub-criteria. Then, the Analytic Hierarchy Process (AHP) is used to calculate the weight of each sub-criterion. With the weight of all sub-criteria when the assessors evaluate the way the assembly makes, the overall score is calculated. The higher overall score means a good assembly model. The second idea is because the assembly can be adjustable and changeable, therefore the assembly’s sequence needed to be considered. The sequence assessment model is developed to calculate the assembly time. The sequence assessment model will use assembly relationship chart and AND/OR graph to set up all the assembly sequence from the beginning to the finished furniture. The smaller assembly time shows the good assembly.

This study evaluates the awareness of green buildings in the West Bank, Palestine, and the importance of applying the green building concept to the public. Green building practices are a significant role in attaining sustainability, particularly in the construction industry. This practice is constructed for minimizing impacts on the environment as well as decreasing building effects on occupants. The key issue is the establishment of a solid knowledge foundation for Palestine that will equip the public, professionals, development agencies and governments with accurate and relevant knowledge generated within the framework of the state’s social needs, its cultures, and its biophysical environment to guide their decisions and actions towards establishing a sustainable built environment. The hypothesis tested was that the implementation of green technology will be beneficial in terms of cost and benefit for the improvement of the environment in West Bank, Palestine. The validity and reliability of data were considered to increase the quality of the data. The results show that there is a positive significant relationship between awareness level and the efficiency of building green practices in West Bank, Palestine. Therefore, motivation and government support are crucial to increase the awareness level of the importance of green building development in West Bank, Palestine. The survey conducted revealed that although the fieldwork professionals are aware of the green building concept, the general public is not aware of this concept as there was only minor efforts are developed in implementing it. A lot more work is necessarily needed to enhance public awareness of the application of green building and further stimulate measures and strategies towards a sustainable built environment.

This study analyses the quality process using the integration of ergonomic and lean six sigma in the DMAIC cycle at CV. Wahana Karya shipyard. The ergonomic uses RULA tools while lean six sigma uses SIPOC diagram tools, current stream mapping, DPOM, Pareto diagrams, cause, and effect diagrams and FMEA. The improvement stage is recommendations for improvement through the highest RPN in the FMEA analysis and recommendations for improving ergonomics from work posture. The control stage is the supervision of the recommended improvements. The result indicates that there are 7 work postures that cause a decrease in quality where one of the risks of high work postures is in wood cutting activities with recommendations for improvement, namely designing ergonomic wood forming and cutting tools, on lean six sigma, recommendations for improving process quality are obtained based on analysis of FMEA tools for installing Advanced hull boards are tenuous hull boards with an RPN value of 384 with recommendations for improvement, namely replacing a new clamp press tool that is easy to install. Meanwhile, in the process of installing the ivory with an advanced level, which is not according to the size of the RPN 336 value, the recommendation for improvement is to make clear and written SOPs and work guidelines.

A study about the antimicrobial activity test of black tea ethanol extract (Camellia sinensis) against Pseudomonas aeruginosa has been carried out. The black tea leaves are sourced from Sidamanik Plantation, North Sumatra. The dried black tea leaf extract was obtained by maceration technique in which black tea leaves were macerated for 24 hours. Then, the macerate was concentrated to obtain a thick extract and make sure that the ethanol had evaporated. After that, the concentrated extract was made with a variation of 5%, 10% and 15%. The antimicrobial activity test used was the disc method, where distilled water was used as a negative blank. The results obtained for average SD for blank with diameter 6 mm, 5%, 10% and 15% extracts were 6 ± 0,00; 7,75 ± 0,35; 9,05 ± 0,07 and 9,95 ± 0,07 mm with the inhibition diameter 0 mm; 1,75 ± 0,35; 2,05 ±0,07 and 3,95 ± 0,07 mm. The conclusion of this study is that the concentration of the extract is straightly proportional to its inhibitory power, namely the higher the concentration of black tea ethanol extract, the higher its inhibitory activity against Pseudomonas aeruginosa, so it can be used as an antibacterial agent for Pseudomonas aeruginosa.
