Hair style allows consumers to express their aesthetic sense and individual beauty. However, due to the attributes of hairdressing services and the high expectations of consumers, complaints are increasing rapidly. This study examined the complaint behavior, compensation and hair salon patronage of consumers. Then, a model is presented that explains the complaint behavior for hairstyling, forms of compensation, and hair salon patronage through empirical analysis. This study was conducted by a survey method. A total of 399 questionnaires were used for the analysis. The data were analyzed using SPSS 23.0 and AMOS 23.0 statistical software. The dimension of complaint behavior for hair style included verbal complaints, non-verbal complaints in the salon and private complaints outside the salon. The forms of compensation included re-procedure, psychological, and material compensation. Hair salon patronage was one-dimensional. These results were obtained through exploratory and confirmatory factor analysis. Then the conceptual model was empirically analyzed by covariance structure analysis and obtained in final form through model modification. Verbal complaint behavior positively influenced re-procedure compensation. In addition, non-verbal complaint behavior had positive effects on psychological and material compensation. Hair salon patronage was positively affected by re-procedure and psychological compensation. However, private complaint behavior had a negative effect on hair salon patronage. The direct and indirect effects of the paths among variables were verified by analyzing the mediating effects of different forms of compensations. It is possible to establish differentiated marketing strategies with these findings for consumers with complaint behaviors by considering the forms of compensation.

This study examines determinants of user immersion for Korean drama and entertainment genre programs among Chinese students in Korea. The major results are as follows: firstly, user immersion for entertainment genre was more greater than that of drama genre. Although drama was tended to evaluated based on star appearance and narrative structure, entertainment program was favored by its pleasure and vividness. Secondly, there were gender differences for entertainment and drama genre programs between male and female respondents. Also, there was a correlation between drama immersion and duration of stay. Thirdly, although determinants of drama immersion were program characteristics, duration of stay and drama preference, those of entertainment immersion were program characteristics, appearance of star players and entertainment preference.

As major industries become information-centered, business transactions and information-sharing processes are being computerized and automated, which ultimately re-defines electronic commercial transactions in a broader context. Business documents are the basic tools for corporate transactions. The use of business documents in electronic commercial transactions has increased markedly and this sphere is rapidly being extended to include information sharing between companies. XML(extensible Markup Language) was selected as the focus for this thesis. XML ran help to make a complicated and data-rich document easy to share. The thesis proposes a business XML document editing system, comprised of a style document editor for business XML document structure, business documentation, and business document presentation, along with a business document transformation system which makes a transformation possible regardless of platform or using various corporate document standards.

In this paper, a vehicle antenna for AM, FM, TDMB, GPS systems was designed and implemented. AM antenna loaded into small space of shark shape was designed by ferrite turn style antenna. For the FM and TDMB antenna, folded monopole antenna which helical is folded was applied. GPS antenna for achieving characteristics both bandwidth and gain improvement was designed microstrip patch that has air substrate and fractal structure. Receiving signal strengths by the measurement were presented for the AM, FM and TDMB antenna. AM signal strength was -65.7dBm, this strength is almost as same conventional pole antenna as -63.4dBm. It can be replaced conventional pole or glass antenna by the studied antenna. Signal strengths for FM and TDMB were -55.66 and -43.50dBm at center frequency, they are 5~10dB higher than conventional antenna. Measurements of bandwidth and gain for the GPS antenna showed 135 MHz under VSWR 2 : 1 and 4.31dBi, gains over GPS band were 3~5dB higher than ceramic patch antenna.

The paper focuses on how to classify as well as to define the Architecture Patterns which are popularly used in the design of software architecture. In order to achieve this purpose, we propose not only the revised methodology for Pattern-Oriented Software Architecture Design, but also new method of classification and definition for the Architecture Patterns. Especially, because the patterns are so diverse depending on the level of abstraction and types of applications, it was considered to have some different views of classification of the patterns in order to support convenient access to classified and stored patterns. The abstraction of the pattern is another important result of the research, which is devised for concrete expression of the patterns and for presentation of the interrelation among group of the patterns. The research also includes the extension of the quality model popularly adopted in the software domain, which enables the description of the patterns with the well defined quality attributes in terms of software architecture's point of view.

This paper aims to show that cooperative robots, which have only been used in manufacturing sites, are expanding their scope of use in daily living spaces due to the expansion of non-face-to-face services. By combining robots and IoT technologies in terms of diversifying services in daily life and customized service areas, it is expected that the general public will also have easy access to smart technologies, and these technologies will be used in more areas. The robot barista system will provide customers with the services they want, monitoring, maintenance, and management of the system, making this paper convenient for customers, as well as managers who run stores, maintenance and repair, and engineers who design the system. This paper attempts to demonstrate this through a structure called Robopresso.

Among the generative models in Artificial Intelligence (AI), especially Generative Adversarial Network (GAN) has been successful in various applications such as image processing, density estimation, and style transfer. While the GAN models including Conditional GAN (CGAN), CycleGAN, BigGAN, have been extended and improved, researchers face challenges in real-world applications in specific domains such as disaster simulation, healthcare, and urban planning due to data scarcity and unstable learning causing Image distortion. This paper proposes a new progressive learning methodology called Progressive Step Training (PST) based on the Auxiliary Classifier GAN (ACGAN) that discriminates class labels, leveraging the progressive learning approach of the Progressive Growing of GAN (PGGAN). The PST model achieves 70.82% faster stabilization, 51.3% lower standard deviation, stable convergence of loss values in the later high resolution stages, and a 94.6% faster loss reduction compared to conventional methods.

In our search for the natural cosmetic ingredients, we found that Euryale ferox seed extract exhibited the strong antioxidative activity. Five active compounds were isolated from the ethyl acetate extract through various chromatographic methods and their structures were determined by NMR and MS spectral analysis. These compounds were identified as fucosterol (1), 3-(4-hydroxy-3-methoxybenzyl)-4-[(7'R),5'-dihydroxy-3'-methoxybenzyl]tetrahydrofuran (2), resorcinol (3), pyrogallol (4) and 4-O-methylgallic acid (5).We evaluated the antioxidative, antielastase activities and melanogenesis inhibitory effects of these compounds. The $SC_{50}$ values of compounds 2 ~ 5 for free radical scavenging activity were $17.0\;{\sim}\;100.2\;{\mu}M$ and especially compounds 4 and 5 were 6-fold more effective than ferulic acid as a positive control. And compounds 2 ~ 4 inhibited human neutrophil elastase with $IC_{50}$ values of $18.8\;{\sim}\;78.2\;{\mu}M$ and compound 3 also inhibited melanin synthesis in B16F10 melanoma cells with an $IC_{50}$ value of $492.8\;{\mu}M$. These results suggest that Euryale ferox extract having a lot of various active ingredients may be useful as a natural multi-functioning agent.
