The objective of this study was to analyze the color distribution of the maxillary primary central incisors and the relationship between the color of each tooth region by dividing tooth into incisal, middle and cervical region using a spectrophotometer. The subjects were 105 sound maxillary primary central incisors from 3 to 6 years old children. Color measurements were performed by one dentist using same protocol. CIE $L^*$, $a^*$, $b^*$, $C^*$, $h^*$ data and the best matched shades with coverage error were obtained for each region and whole labial surface. There was a significant difference in CIE $L^*$, $a^*$, $b^*$ according to regions and the difference in color between each region was more than the clinical acceptance. By correlating the relationship between the color of each region with $L^*$, $a^*$, $b^*$ values, it is possible to extrapolate the color of other region with one color or to be used as data for making restorative materials and prostheses that are more aesthetically pleasing for primary teeth.

To improve the standard of living of its citizens, local festivals is located in one axis of the new culture. These symptoms shows that there is increasing awareness of traditional culture such as Hanryu. The purpose of this study is to develope the presentative Dress of Andong International Maskdance Festival to stimulate curiosity and participate easily. 24 villages in Andong were present to represent appropriate Dress of Maskdance Festival which have been announced through the fashion show. The characteristics of the maskdance dress which presented in this study has the purpose of making the specialties of each village to tourism resources. Characteristics of the maskdance dress which designed to blend on the mask was as following. (1) Maskdance dress should shown well and must have strong durability of strenuous exercise in maskdance (2) Maskdance dress should be able to get the sympathy of the spectators. (3) Maskdance dress should be sympathetic as modern costumes. (4) Aesthetics as custumes and requirements as product must be met. (5) Acceptance of Andong region's traditional beauty is required. (6) Maskdance dress is likely to require long-term use. (7) Maskdance dress must be able to accommodate a variety of body conditions. Through customer satisfaction survey of 158 spectators and 48 members of fashion show, the relevance of masks and costumes, aesthetic and motility of costumes, commercialization potential, especially costume' motility and functional fitness of clothing sizes was highly evaluated. So maskdance dress or stage costumes as long-term development is likely to be considered. And continued research is needed.

Information technology and the need for timely and effective communication during the Covid-19 have made most governments adopt technological approaches to provide their services. E-government services have been adopted by most governments especially in developed countries to quickly and effectively share information. This study discusses the reasons why governments in the Gulf region should develop a new model for information technology knowledge management practices. To achieve this, the author identified possible benefits of adopting information technology knowledge management practices and why most governments in the Gulf find it hard to adopt them. Knowledge management allows for learning, transfer as well as sharing of information between government organizations and citizens and with the development of technology, the effectiveness of electronic services can easily be achieved. Also, effective adoption of information technology can improve knowledge management with the help of techniques that enhance capture, storage, retrieval as well as sharing of information. The author used systematic literature review to select 28 journals and articles published post 2019. IEEE, Google Scholar and Science Direct were used to select potential studies from which 722 journals and articles were selected. Through screening and eligibility assessment, 21 articles were retained while the back and forward search had 7 more articles which were also included in the study. Using information gathered from these articles and journals a new conceptual model was developed to help improve information technology knowledge management for governments in the Gulf region to effectively deliver e-services during Covid-19. This model was developed based on the process of KM, Theory of Planned Behavior and Unified Theory of Acceptance and Use of Technology. Based on the developed model. From UTAUT model, performance expectancy, effort expectancy as well as social influence had a great impact.

This study develops a traditional green fabric pattern design through an apparel CAD system. The method used simulated stage costumes and evaluated the consumer satisfaction connected with a 3D fitting system. The results are as follows. Computerization of the pattern making process can provide higher accuracy and efficiency in apparel pattern making and marking for green fabrics. A Stage costumes design was developed; subsequently, the developed dress patterns are automatically depicted to the input of the body size of the consumer and marked using marking program. This results show that it has an effect on narrow and expensive green fabrics. Stage costumes design can make a simulation by a 3D Fitting system. The results of this study can provide higher consumer satisfaction through a survey of 30 consumers. Stage costumes should attract the sympathy of the spectators. The Acceptance of Andong region's traditional beauty is required. We found that a relationship of performance and clothes, physical functionality and beauty of costumes, possibility of commercialization, and the possible use of a 3D Fitting system use are evaluated. A continuous study of regional culture resources is required since there is a significant possibility for the long-term development of stage clothes.

Superelastic Shape Memory Alloys (SMAs) are gaining acceptance for use as reinforcing bars in concrete structures. The seismic behaviour of concrete frames reinforced with SMAs is being assessed in this study. Two eight-storey concrete frames, one of which is reinforced with regular steel and the other with SMAs at the plastic hinge regions of beams and regular steel elsewhere, are designed and analyzed using 10 different ground motion records. Both frames are located in the highly seismic region of Western Canada and are designed and detailed according to current seismic design standards. The validation of a finite element (FE) program that was conducted previously at the element level is extended to the structure level in this paper using the results of a shake table test of a three-storey moment resisting steel RC frame. The ten accelerograms that are chosen for analyzing the designed RC frames are scaled based on the spectral ordinate at the fundamental periods of the frames. The behaviour of both frames under scaled seismic excitations is compared in terms of maximum inter-storey drift, top-storey drift, inter-storey residual drift, and residual top-storey drift. The results show that SMA-RC frames are able to recover most of its post-yield deformation, even after a strong earthquake.

In thin paper, error tolerance of each array element which satisfies error tolerance of beam pattern is decided by using the Monte-Carlo method. Conventional deterministic method decides the error tolerance of each element from the acceptance pattern by testing all cases, but this method is not suitable for the analysis of large number of array elements because the computation resources increase exponentially as the number of array elements increases. To alleviate this problem, we applied new algorithm which reduces the increment of calculation time increased by the number of the array elements. We have validates the determined error tolerance region through several simulation.
