The purpose of this study is to investigate the relationship between the development of laterality and bilateral motor abilities measured with respect to various rhythm movements in upper extremity of mentally retared children. The development of laterality was measured by a survey of dominace-hand. The bilateral motor abilities were assessed by means of a tentative rhythm beat test of hands. One hundred sixty eighty subjects with special education needs shose age ranged from 7 to 18 years old were used for an experimental group. Fity nine normal children whose age ranged from 3 to 6 years old were also chosen as a control group. The major findings were as follows : (1) The development of lateral dominace-hand in mentally retared children differed from that of normal subjects with an increase in chronological age ; the mean level of the normal children. Though normal children establish a dominance-hand by ths age of years old, meatally retarded children are likely to show 57 percent of normal development at the age of 7 through 9 years old and 65 percent of normal development at the age of 16 through 18 years old. (2) A greater delay in mentally retarded children was found through a rhythm test which was development to assess bilateral motor abilities in upper extremity. A closer relationship betwin chronological age and the development of bilateral motor abilities in mentally retared children was found. (3) In view of these findings, it was indicated that bilateral motor abilities of the retarded and non-retarded children were significantly correlated to the acqusition of dominance-hand.

The use of O2O platforms are gradually increasing. This study reclassifies the preceding factors of trust in ‘Kakao Hairshop’ linked to hair salon services, and examine the process leading to platform loyalty based on the satisaction transfer theory. It is meaningful to consider not only the platform itself but also the hair salon, which is an offline entity that is actually used, in order to examine the actual online and offline connection. This study developed a research model and analyzed 271 responses from individuals who visited the hair salon through the Kakao Hairshop mobile O2O platform. Structural model analysis revealed that, except for perceived risk, the other two dimensions of perceptions toward the O2O platform(i.e., perceived quality and reputation) significantly influence trust in Kakao Hairshop. Moreover, trust was found to affect satisfaction with the hair salon service, and satisfaction with Kakao Hairshop, as well as continue to use Kakao Hairshop. Offline satisfaction was confirmed to impact satisfaction with the online platform, and this, in turn, was connected to the intention to continue using the platform. Additionally, it was confirmed that satisfaction with the hair salon also influences the intention to revisit the same hair salon. The findings of this research establish a basis for future related follow-up studies and are expected to offer guidance for O2O service developers and field practitioners in formulating development plans.

According to the change of customer needs, integration with other systems, and the advent of new technology, it is inevitable for the existing system requirements to be requested to redesign. However, there are actually no methodologies and processes to be able to reorganize the existing requirements or integrate a number of requirements different from each other. The traditional requirements processes do not work when solving such problems. Thus, since the existing approaches to develop requirements are not helpful, many traditional requirement engineering processes can not help falling in Red Ocean. In this paper, in order to solve such the problems, we propose a novel requirements engineering process applying Blue ocean strategy which is used to open a non-competition market not discovered yet. Blue Ocean approach is a novel effective method to elicit and build up new requirements from customers. In order to accomplish the strategy, this paper presents a framework and processes to discover new perspectives and analyze the corresponding requirements. In addition, some pieces of case study are presented to introduce how our approach is applied to practical system developments and the evaluation analysis for how valid it is.

To increase the biocompatibility and durability of glutaraldehyde (GA)-fixed valves, a biological coating with viable endothelial cells (ECs) has been proposed. However, stable EC layers have not been formed successfully on GA-fixed valves due to their inability to repopulate. In this study, to improve cellular adhesion and proliferation, the GA-fixed prostheses were detoxified by treatment with citric acid to remove free aldehyde groups. Canine bone marrow mononuclear cells (MNCs) were differen - tiated into EC-like cells and myofibroblast-like cells in vitro. Detoxified prostheses were seeded and recellularized with differentiated bone marrowderived cells (BMCs) for seven days. Untreated GA-fixed prostheses were used as controls. Cell attachment, proliferation, metabolic activity, and viability were investigated and cell-seeded leaflets were histologically analyzed. On detoxified GA-fixed prostheses, BMC seeding resulted in uninhibited cell proliferation after seven days. In contrast, on untreated GA-fixed prostheses, cell attachment was poor and no viable cells were observed. Positive staining for smooth muscle α-actin, CD31, and proliferating cell nuclear antigen was observed on the luminal side of the detoxified valve leaflets, indicating differentiation and proliferation of the seeded BMCs. These results demonstrate that the treatment of GA-fixed valves with citric acid established a surface more suitable for cellular attachment and proliferation. Engineering heart valves by seeding detoxified GA-fixed biological valve prostheses with BMCs may increase biocompatibility and durability of the prostheses. This method could be utilized as a new approach for the restoration of heart valve structure and function in the treatment of end-stage heart valve disease.
