Germ cell-specific hyaluronidases such as sperm adhesion molecule 1 (SPAM1) and hyaluronoglucosaminidase 5 (Hyal5) are in part responsible for dispersal of the cumulus cell mass, which is a critical step in establishing fertilization in mammals. In this study, we identified two testis-hyaluronidases, SPAM1 and Hyal5, in hamster and rat. These two genes were expressed specifically in the testis. At the protein level, hamster SPAM1 and Hyal5 display 78.7% and 75.4% identity with mouse SPAM1 and Hyal5. Further, the activity of the enzymes with respect to cumulus cell dispersion did not differ, although we observed that the enzymatic activity differed in pH range. These studies suggest that different sperm hyaluronidases are capable of dispersing the cumulus cell mass despite differences in enzyme activity.

The purpose of the present research was to investigate (I) the acquisition of character constancy of self and others as a function of age; (2) the pattern of acquisition of character constancy, and (3) the relationships between character constancy and conservation of number and mass. The subjects of this study were 160 children, 20 boys and 20 girls at each grade level, kindergarter through grade 3. The Character Constancy Tasks devised bi Rotenberg (1982) and conservation task of number and mass were administered to each child. Chi square, Guttman Scale analysis and Pearson's Correlation were used for the statistical analysis of data. The findings showed that there was increase with age in character constancy of others and of sell in that there was increase with age in children's belief that the characteristics of another person are stable across time and consistent despite changes in a person's appearance. Character constancy of others and of self were acquired in the developmental stages of identity, stability, and consistency. Character constancy of others and self correlated with the conservation of number and mass.

Neuropeptides produced from prohormones by selective action of endopeptidases are vital signaling molecules, playing a critical role in a variety of physiological processes, such as addiction, depression, pain, and circadian rhythms. Neuropeptides bind to post-synaptic receptors and elicit cellular effects like classical neurotransmitters. While each neuropeptide could have its own biological function, mass spectrometry (MS) allows for the identification of the precise molecular forms of each peptide without a priori knowledge of the peptide identity and for the quantitation of neuropeptides in different conditions of the samples. MS-based neuropeptidomics approaches have been applied to various animal models and conditions to characterize and quantify novel neuropeptides, as well as known neuropeptides, advancing our understanding of nervous system function over the past decade. Here, we will present an overview of neuropeptides and MS-based neuropeptidomic strategies for the identification and quantitation of neuropeptides.

In recent years, a pattern recognition method has been widely used by researchers for fault diagnoses of mechanical systems. A pattern recognition method determines the soundness of a mechanical system by detecting variations in the system's vibration characteristics. Hidden Markov model has recently been used as pattern recognition methods in various fields. In this study, a HMM method for the fault diagnosis of a mechanical system is introduced, and a rotating machine with mass unbalance is selected for fault diagnosis. Moreover, a diagnosis procedure to identity the size of a defect is proposed in this study.

Today, the market environment for companies around the world has been changed by globalization, digital innovation, information by opening the diversity, consumer awareness, and the development of mass media in the wide areas such as, politics, economy, society and culture. Accordingly, the function of the housing cultural center also has been changed from the Place where the trading had been made to the Space where the marketing could work. The housing cultural center is home to companies to target their corporate culture and corporate image, and the brand identity. From the space marketing standpoint, this study extracts differentiator of the housing cultural center from theoretical consideration to boom up of the housing cultural center and to build up its identification. Based on this analysis, the design identity element of the interior design of the housing cultural center is proposed by the actual and analytical cases. Such a future plan design identity elements in the design of the new housing cultural center is providing basic design guide line to recognize the importance.

Among diverse cultural types which can be shown in movie, 'Subculture' is young culture that resist to major culture. It shows its belief and identity via its own style. Their 'Subcultural Style' became popular with mass media and has been affected to major cultures. Therefore, in this research, with times background as postmodernism in end of 20th century and mainly with movie which is about sexual minorities, I analyzed categories of costumes in the movie. Hedwig's rock costume shows combined fashion with hippie, punk, glam, kitsch, goth styles from the impact of postmodernism in mid 20th century. Tommy, showed his relief and defiant intention against old generations with grunge casual and graffiti styles. After he realized Hedwig's identity and showed defiant goth rock style as a famous rocker. The band, "Angry Inch", showed dissatisfaction and cynical attitude against the American society through subculture styles. Through this research, the fact that movie costume used a tool to show human's identity and value. Also, I can see that movie costume shows times and cultural phenomenon in the end of 20th century and through this, it was confirmed that this contributes to crease new fashion style through them.

In the twentieth century, due to extraordinary development of companies and life style, etc, market environments to which companies around the world currently face are being changed with reflecting the current age in various fields, which result from globalization, digitalized innovation, diversity by information acceptance, an enhanced level of a consumer's consciousness, developed mass media, etc. The companies are trying to expand their sale areas, not only products but also their cultures, images, and brand power in the name of a 'marketing' in a space In other words, if companies and brands express some identities without considering an entire image evaluated by customers, a mis-positioning for the companies and the brands may be caused. In this case, the companies and brands may not influence on potential major customers at all, of an image for the companies and brands may be degrade Accordingly, a space marketing is required as a distinguished strategic means in characterizing identities according to brands. Also, a design for communicating the space marketing with the customers is required. Therefore, the purpose and effects of the present research are to analyze how identity characteristics for brands and company images are reflected by analyzing a faadeof a hall for housing cultures, and are to analyze how they are recognized by customer.

The purposes of this study are to examine the concept of customized fashion product design as a new industrial paradigm reflecting individual customers' needs in modern society, and to grasp its sociocultural meaning. It is thought that this study will be helpful to investigate the cultural thinking of contemporaries represented through the consumption. For this, the documentary study and practical case study have been executed. As modern fashion business becomes more consumer-oriented due to the industrial paradigm shift, there appeared the prosumer as both consumer and producer. The type of customized fashion product design can be classified as 1) the traditional custom-made design in haute couture and classic tailoring 2) the tailor-made design in the prestige line of ready to wear 3) DIY custom design 4) mass customized design of customer involvement. The traditional custom-made design in haute couture and classic tailoring and the tailor-made design in the prestige line of ready to wear is to provide the distinguished product which has the best quality as well as the excellent beauty for VIP consumer. The DIY custom design is for creative consumer searching for the fun of craftsmanship to take part in producing personally. The mass customized design of customer involvement is to personalize product by selecting design module in mass production. Ultimately the sociocultural meaning of the customized fashion product design can be interpreted as (1)endowing special meaning to personal identity (2)distinguishing the privilege by rarefied authenticity (3)returning to analog sensibility 4)pursuing creative fun 5)thinking in a user-centered way.

In recent years, pattern recognition methods have been widely used by many researchers for fault diagnoses of mechanical systems. The soundness of a mechanical system can be checked by analyzing the variation of the system vibration characteristic along with a pattern recognition method. Recently, the hidden Markov model has been widely used as a pattern recognition method in various fields. In this paper, the hidden Markov model is employed for the fault diagnosis of the mass unbalance of a rotating system. Mass unbalance is one of the critical faults in the rotating system. A procedure to identity the location and size of the mass unbalance is proposed and the accuracy of the procedure is validated through experiment.
