The aim of the study is to develop a jean jacket and pants of easy-to-move for schoolgirls of 11 years old. The research was carried out as follows; 1. Using a manufacturer's pattern, a jean jacket and pants were made. 2. Based on the survey of 108 schoolgirls, interviews with 4 designers of children's wear, and wearing test, three trial garments were developed. -Certain areas such as knee, elbow, and hip should be altered to have better extensibility. -The weight of the garment would be better to be reduced. 3. Three trial garments were developed using following techniques, which were found in fashion magazines for kids very often. -Alter the location and the shape of the seam line so that the areas mentioned above can adjust the movement of the body better. -Match stretchable material at the areas which require better extensibility. -Use various trimmings to make the garment more size adaptable and easy-to-move. 4. These garments were tested by 26 schoolgirls, and they answered the questionnaires focused on the design preference and easy-to-move. 5. From the results of the wearing test of three trial garments, more effective techniques were selected. Using these techniques, prototype garment was developed. The prototype garment was approved by the wearing test of 26 schoolgirls.

Purpose The purpose of this study is to investigate the resistance factors interfering the acceptance factors of the mobile easy remittance service focusing on the switching cost and the innovation resistance model. Design/methodology/approach This study focuses on revealing the resistance factors of the mobile easy remittance service acceptance. The resistance factor is designed consisting both consumer characteristics and service characteristics in the Innovation Resistance Model. Furthermore, the effect of resistance factors on the innovation resistance and acceptance intentions were detected by moderating the switching cost. Findings According to the empirical analysis result, this study investigated the effect of resistance factors on innovation resistance and acceptance intention for the mobile easy remittance service. The results of this study as follows; (1) The consumer's inherent innovativeness did not significantly affect the innovation resistance and acceptance intention. (2) The attitude toward existing services and complexity significantly affected innovation resistance in direct manner, thus affecting the acceptance intention in indirect manner. (3) The perceived usefulness significantly affected both the innovation resistance and the acceptance intention in direct manner. (4) The perceived risk only effected the acceptance intention. (5) The switching cost had a moderating effect on the innovation resistance and acceptance intention.

A new and efficient method for the preparation of substituted 3,4-dihydropyrimidin-2(1H)-ones via Biginelli synthesis using catalytic amounts of 1,3-dichloro-5,5-dimethylhydantoin is presented. Short reaction times, easy work-up, high yields of products and stability, easy-handling, non-toxicity and cheapness of the catalyst are noteworthy advantages of the present work.

This study identifies possible determinants that may have influences on the switching behavior from the current payment system of credit or check cards to the easy payment service based on push-pulling-mooring model. And this research empirically tests how those determinants affect switching intention to the easy payment service. The moderating effect of policy expectation is also taken into account. The findings show switching intention to the easy payment service is influenced by the followings: dissatisfaction with the current payment system as a pushing factor, perceived easy of use and trust in easy payment service as pulling factors, and affective/cognitive inertia and unfavorable subjective norm as mooring factors. The results also show that moderating effect of policy expectation exists in the relationship between perceived ubiquitousness and switching intention.

The aim of this study was to compare the apical sealing ability of a new thermoplasticized gutta-percha filling technique, the Easy Filling and the Quick Obturation system with lateral condensation technique and Thermafil system to evaluate their clinical acceptabilities. Fifty-two extracted single-rooted teeth were instrumented to #35 using the .04 taper ProFile system. Four groups of 12 teeth were obturated by lateral condensation technique. Thermafil system and two new thermoplasticized gutta-percha techniques, the Easy Filling system and Quick Obturation system (Meta Dental co. Ltd. Korea), respectively. Four teeth served as controls. After the teeth were immersed in 2% methylene blue dye for 48 hours, they were resected horizontally at 1mm to 5mm level from the anatomical apex using a low-speed microtome. Each section was examined under a stereomicroscope at ${\times40}$ magnification and photographed. After each image was scanned, the leakage area was measured at each level using Brain 3 (Nosdia Tech., Korea) software. Leakage ratio was calculated for each group and was analyzed statistically to come up with the following results: 1. At 1mm level, the Quick Obturation system had the largest amount of apical leakage and it was statistically significant when compared with the lateral condensation group and the Thermafil group (p<0.05). 2. At 2mm and 3mm level, there were no significant difference of apical leakage among all four groups (p>0.05), and from 4mm level, no apical dye penetration was observed in all the groups. In conclusion, the apical seal produced by Easy Filling system and the Quick Obturation system was comparable to lateral condensation technique and Thermafil system except for the 1mm level. More improvement of the apical seal can be expected as the operator becomes skillful with the new techniques.

Objective: This study aims investigate the moderating effect of mothers' overprotective parenting in the influence of young children's competence, as determined by their temperament, on mastery motivation. Methods: An online survey was conducted on 429 mothers with children aged 3-5. The collected data was analyzed using K-means clustering in SPSS 23.0 and the Process macro Model 2. Results: Children's temperaments were categorized into four types : easy-active temperament, easy-inactive temperament, slow temperament, and difficult temperament. It was confirmed that children's competence directly affected their mastery motivation when they had easy-inactive, slow, or difficult temperament. It was also found that mothers' intrusive control had a direct main effect on object persistence when children had easy temperament, while there was no effect on mastery pleasure. The moderating effects of mothers' anxious protection on the pathway from children's competence to object persistence were significant only among children with a slow temperament. Conclusion/Implications: This study highlights the need for mothers to adapt their parenting behavior to their children's temperament type. The study confirmed partial moderating effects of mothers' overprotective parenting in the influence of children's competence, as determined by their temperament, on mastery motivation.

The GMR-SV (giant magnetoresistance-spin valve) device depending on the micro patterned features according to two easy directions of longitudinal and transversal axes has been studied. The GMR-SV multilayer structure was Ta(5 nm)/NiFe(8 nm)/Cu(2.3 nm)/NiFe(4 nm)/IrMn(8 nm)/Ta(2.5 nm). The applied anisotropy direction of the GMR-SV thin film was performed under the magnitude of 300 Oe using by permanent magnet during the deposition. The size of micro patterned device was a $1\;{\times}\;18\;{\mu}m^2$ after the photo lithography process. In the aspects of the shape magnetic anisotropy effect, there are two conditions of fabrication for GMR-SV device. Firstly, the direction of sensing current was perpendicular to the magnetic easy axis of the pinned NiFe/IrMn bilayer with the transversal direction of device. Secondly, the direction of shape magnetic anisotropy was same to the magnetic easy axis of the free NiFe layer with the longitudinal direction of device.
