Mixture phenomena are present in the overall culture due to internationalization in a modern society. A unique feel is required in materials due to the increasing demand for knit wear and there is a need for a strategic plan to achieve this. This study analyzed the appearance frequency and expressive characteristics of mixture phenomena based on selected data from collections related to the mixture phenomena trends in modern women's fashion from 2000 to 2008. Among the mixture phenomena, the mixture of the high and low class cultures had the highest frequency of occurrence and was expressed most often since the expansion of design areas was due to vague high and low concepts. The mixture of sexes showed the sharing of knit wear trends between the sexes with the pursuit of functionality. The mixture of styles showed a tendency to increase since the traditional form was transformed into a mixture of typical styles. The mixture of spaces showed a mixture of old and traditional knit wear patterns from Northern Europe and modern elements. The mixture of other materials showed the partial preceding mixture and the decorative materials that existed beyond it. The mixture of functions refers to the used characteristics of the two items. Imagination will grow and increase the possibility of expressions with the mixture of the other areas.

With the development of the society, people's thought and the way of life is changing. The change of the traditional values and marriage lead to the increase of the "singles" groups in modern society. The "singles" group's behaviors, living environment, and consumption have become a social focus. With the emergence of the "singles", traditional furniture already can't meet the demand, so personalized furniture should be developed for the "singles". This study based on background and consumption psychology of the "singles", analyzed the consumption characteristics and preferences of the "singles". It studied the furniture demand of the "singles", and analyzed the existing unmarried person's residential form, types and characteristics of the furniture, and also analyzed the existing furniture using by the "singles" with SWOT, made a more systematic study for finding the advantages and disadvantages of existing the "singles" group's furniture. Then, combined with the unmarried person's furniture needs, living forms, the advantages and disadvantages of the "singles" furniture, etc., made the multi-functional furniture design concept for the "singles". This concept as a design direction, which would make out more suitable furniture be in keeping with the "singles" group's characteristics and requirements. Finally through the concept of multi-functional and folding raise the utilization ratio of narrow space of the living environment.

Microorganism survived in the root canal after root canal cleaning and shaping procedure is a main cause of root canal treatment failure. There are several mechanisms for the bacteria to survive in the root canal after chemomechanical preparation and root canal irrigation. Bacteria organized as biofilm has been suggested as an etiology of persistent periapical lesion. Recent studies were focus on removal of Enterococcus faecalis biofilm due to the report that the persistence of this bacteria after root canal treatment may be associated with its ability to form biofilm. Several investigations demonstrated that current root canal treatment protocol including use of NaOCl, EDTA and Chlorhexidine as irrigants is quite effective in eliminating E. faecalis biofilm. However, this microorganism still can survive in inaccessible areas of root canal system and evade host immune response, suppress immune activity and produce biofilm. Up to date, there is no possible clinical method to completely get rid of bacteria from the root canal. Once the root canal treatment failure occurred, and conventional treatment incorporating current therapeutic protocol has failed, periapical surgery or extraction should be considered rather than prolong the in effected retreatment procedure.

In this paper, we propose a computerized psychological test system for art therapy. The proposed system with the computerized devices can measure various information, such as colors, characters of lines, pen pressure, size of objects, position of objects, and so on, from the drawn pictures by the child. The measured information can be analyzed to extract more meaningful information about the child and to provide more effective remedial information for art therapy. Art therapy essentially has a potential drawback that the results of test can be influenced by therapist's subjectivity. The results can be different from the method of gathering information, the method of analysis, the interpretation of analyzed data, and even the therapist's academic backgrounds. Therefore, in this paper, we focus on what information needs to be measured and how to measure the data from drawn pictures and propose a computerized psychological test system for art therapy. The proposed system can measure and analyze various information from the drawn picture by the child. Since the proposed system can provide valuable psychological information of child in the form of quantitative data, it can be exploited as a new method for art therapy.

Laser-based crystallization techniques are ideally-suited for forming high-quality crystalline Si films on active-matrix display backplanes, because the highly-localized energy deposition allows for transformation of the as-deposited a-Si without damaging high-temperature-intolerant glass and plastic substrates. However, certain significant and non-trivial attributes must be satisfied for a particular method and implementation to be considered manufacturing-worthy. The crystallization process step must yield a Si microstructure that permits fabrication of thin-film transistors with sufficient uniformity and performance for the intended application and, the realization and implementation of the method must meet specific requirements of viability, robustness and economy in order to be accepted in mass production environments. In recent years, Low Temperature Polycrystalline Silicon (LTPS) has demonstrated its advantages through successful implementation in the application spaces that include highly-integrated active-matrix liquid-crystal displays (AMLCDs), cost competitive AMLCDs, and most recently, active-matrix organic light-emitting diode displays (AMOLEDs). In the mobile display market segment, LTPS continues to gain market share, as consumers demand mobile devices with higher display performance, longer battery life and reduced form factor. LTPS-based mobile displays have clearly demonstrated significant advantages in this regard. While the benefits of LTPS for mobile phones are well recognized, other mobile electronic applications such as portable multimedia players, tablet computers, ultra-mobile personal computers and notebook computers also stand to benefit from the performance and potential cost advantages offered by LTPS. Recently, significant efforts have been made to enable robust and cost-effective LTPS backplane manufacturing for AMOLED displays. The majority of the technical focus has been placed on ensuring the formation of extremely uniform poly-Si films. Although current commercially available AMOLED displays are aimed primarily at mobile applications, it is expected that continued development of the technology will soon lead to larger display sizes. Since LTPS backplanes are essentially required for AMOLED displays, LTPS manufacturing technology must be ready to scale the high degree of uniformity beyond the small and medium displays sizes. It is imperative for the manufacturers of LTPS crystallization equipment to ensure that the widespread adoption of the technology is not hindered by limitations of performance, uniformity or display size. In our presentation, we plan to present the state of the art in light sources and beam delivery systems used in high-volume manufacturing laser crystallization equipment. We will show that excimer-laser-based crystallization technologies are currently meeting the stringent requirements of AMOLED display fabrication, and are well positioned to meet the future demands for manufacturing these displays as well.

This study was conducted to develop a service quality measurement scale suitable for the fast food restaurant segment. After reviewing the relevant literature, it was decided that the current service quality measurement scales (SERVQUAL, SERVPERF, DINESERV) are not appropriate for the fast food restaurant segment. Based on Cronin & Taylor's (1994) argument, perceived service quality is a form of attitude that represents a long-term overall evaluation of the company. Therefore, this study selected SERVPERF items for the initial pool of service quality items. Through a systematic scale development process, the SERVPERF instrument was then refined and a new concise scale was produced. Specifically, a focus group discussion with a group of patrons who are very familiar with fast food restaurants was conducted and the new service quality measure was refined so that it would be more realistic and closely describe service operation in the fast food industry. Moreover, the data collected from 112 college students who visit fast food restaurants frequently were used to statistically evaluate each of the items again via EFA (Exploratory Factor Analysis) and three sub-dimensions were derived: (1) responsiveness, (2) tangibles, and (3) reliability. Additionally, the data collected from 179 fast food restaurant consumers was used to conduct CFA (Confirmatory Factor Analysis). During this process, the convergent validity, discriminant validity, and internal consistency were double-checked. Overall, the newly developed scale achieved validity and reliability on a theoretical and statistical basis. Possible interpretations and managerial implications are also suggested.

The purpose of this study was to identify the factors affecting job satisfaction in dental hygienists with and without schoolwork, who form professional manpower in dental clinics, and provide basic data that could help develop detailed plans for reducing the turnover intention and improving job satisfaction. For data collection, convenience sampling was performed among clinical dental hygienists at dental clinics in Daejeon and Chungcheong and Gyeongsang Provinces from July 20 to September 20, 2019, and a self-administered questionnaire was used and the data were analyzed by T-test, One-way Anova, Pearson correlation, Stepwise multiple regression analysis, etc. using IBM SPSS/WIN 20.0. For the dental hygienists with schoolwork, job stress was negatively correlated with professional self-concept and job satisfaction, and professional self-concept was positively correlated with job satisfaction; for the dental hygienists without schoolwork, job stress was negatively correlated with professional self-concept and job satisfaction, and professional self-concept was positively correlated with job satisfaction. The factors affecting job satisfaction were professional self-concept, job stress, and age of ≥30 for the dental hygienists with schoolwork and professional self-concept, job stress, and the position as a middle manager for those without schoolwork. To put these results together, professional self-concept and job stress were factors affecting job satisfaction for dental hygienists with and without schoolwork. It is necessary to focus on the formation of good dental organizational culture through positive institutional support as well as through systematic establishment of professional self-concept.

The peculiar feature of cathodic protection in seawater has the capability to form mineral calcareous deposits such as magnesium and calcium on metal surfaces. It is assumed that $OH^-$ ions are generated close to the metal surface as a result of cathodic protection and generated $OH^-$ ions increases the pH of the metal/seawater interface outlined as the following formulae. (1) $O_2+2H_2O+4e{\rightarrow}4OH^-$, or (2) $2H_2O+2e{\rightarrow}H_2+2OH^-$. And high pH causes precipitation of $Mg(OH)_2$ and $CaCO_3$ in accordance with the following formulae. (1) $Mg^{2+}+2OH^-{\rightarrow}Mg(OH)_2$, (2) $Ca^{2+}+CO{_3}^{2-}{\rightarrow}CaCO_3$. The focus of this study was to increase the amount of $CO{_3}^{2-}$ with the injection of $CO_2$ gas to the solution for accelerating process of the following formulae. (1) $H_2O+CO_2{\rightarrow}H_2CO_3$, (2) $HCO^{3-}{\rightarrow}{H^+}+CO{_3}^{2-}$. Electrodeposit films were formed by an electro-deposition technique on steel substrates in solutions of both natural seawater and natural seawater dissolved $CO_2$ gas with different current densities, over different time periods. The contents of films were investigated by scanning electron microscopy(SEM) and X-ray diffraction(XRD). The adhesion and corrosion resistance of the coating films were evaluated by anodic polarization. From an experimental result, only $CaCO_3$ were found in solution where injected $CO_2$ gas regardless of current density. In case of injecting the $CO_2$ gas, weight gain of electrodeposits films hugely increased and it had appropriate physical properties.

Increasingly, the emphasis in regional Passenger rail Planning is finding ways to more efficiently use existing facilities, with particular attention being Paid to Policies designed to spread Peak-Period travel demand more evenly throughout the week with consideration of train classification. In this context the individual's choice of time to travel is of crucial significance. This paper investigates the use of multinomial logit analysis to model ridership by rail classification using data collected for travel from Seoul to Busan during the one week in October 2004. The Particular model form that was successfully calibrated was the multinomial logit (MNL) model : it describes the choice mechanism that will Permit rail systems and operations to be planned on a more reliable basis. The assumption of independently and identically distributed(IID) error terms in the MNL model leads to its infamous independence from irrelevant alternatives (IIA) property. Relaxation of the IID assumption has been undertaken along a number or isolated dimensions leading to the development of the MNL model. For business and related rail travel patterns, the most important variables of choice were time and frequency to the chosen destination. The calibrated model showed high agreement between observed and Predicted market shares. The model is expected to be of use to railroad authorities in Planning and determining business strategies in the Increasingly competitive environment or regional rail transport.
