  • This study examines the factors that influence the actual usage of mobile shopping applications among Generation Y (Gen Y) users in Thailand, determined by behavioral intention, compatibility, perceived cost, perceived ease-of-use, perceived usefulness, perceived risk, and personal innovativeness. The researcher carried out the analysis based on a quantitative approach and used a non-probability sampling as the convenience sampling tool. A total of 502 Gen Y respondents who experienced using the top-four ranking mobile shopping applications in Thailand were invited to participate in the study. The Structural Equation Model (SEM) and Confirmatory Factor Analysis (CFA) were used to analyze the model fit, reliability, and validity of the variables. The primary result revealed that perceived usefulness has the strongest positive significant effect on behavioral intention, followed by personal innovativeness and compatibility. Conversely, the perceived cost has a significant negative influence on behavioral intention. Besides, perceived ease-of-use has a significant positive effect on perceived usefulness. The direct relationship between perceived usefulness and behavioral intention is, however, insignificant. Similarly, the result showed no effect of perceived risk towards behavioral intention. Finally, the result also revealed that behavioral intention determined the actual usage of mobile shopping applications of Gen Y users in Thailand.

  • Infinity is one of the important concept in mathematics, science, philosophy etc. In history of mathematics, potential infinity concept conflicts with actual infinity concept. Reason that mathematicians refuse actual infinity concept during long period is because that actual infinity concept causes difficulty in our perceptions. This phenomenon is called epistemological obstacle by Brousseau. Potential infinity concept causes difficulty like history of development of infinity concept in mathematics learning. Even though students team about actual infinity concept, they use potential infinity concept in problem solving process. Therefore, we must make clear epistemological obstacles of infinity concept and must overcome them in learning of infinity concept. For this, it is useful to experience visualization about infinity concept. Also, it is to develop meta-cognition ability that students analyze and control their problem solving process. Conclusively, students must adjust potential infinity concept, and understand actual infinity concept that is defined in formal mathematics system.

  • This study is intended to compare an actual wedding dress being made completely through 3D software, and compare it with an actual dress of a real model by using collective tools for comparative analysis. The method of the study was conducted via a literature review along with the production of the dresses. In the production, two wedding dresses for the small wedding ceremony were designed. Each of the design was made into both 3D and an actual garment. The results are as follows. First, the 3D whole body scanner reflects the measure of the exact human body size, however there were some difficulties in matching what the customer wanted, because the difference of the skin color and the hair style. Second, the pattern of the dress is much more easily altered than it was in the real production. Third, the silhouette of the virtual and the actual person with the dress was nearly the same. Fourth, textile tool was much more convenient because of the use of real-time rendering on the virtual dresses. Lastly, the lace and biz decoration were flat, and the luster was duller than in reality. Prospectively, the consumer will decide their own design of variety through the use of the avatar without wearing the actual dresses, and they would demand what the another one desired, different from the presented ones by making the corrections by themselves. Through this process, the consumer would be actively participating in the design, a step which would finally lead to the two way designing rather than the one way design of present times.

  • The purpose of this study was to research the actual state of mother's internet use and to explore the possibility of the internet use as a social support. The affect of mother's internet use on maternal efficacy is also examined. The Subjects were 250 mothers, who have their first child under 8 years old, in Seoul and Ilsan. Data were gathered through questionnaires. As predicted, mother's internet use was popular among young mothers. And, the main reason of internet use of mothers was to find some information on parenting and nurturing child. Moreover, mothers believed that they could get some social support from using internet in terms of informational, instrumental, and emotional service. However, it should be noted that mother's perceived level of support was significantly different, depending on mother's age, level of mother's education, household income, and the age of the first child. It was also found that mothers who received social support from internet showed higher material efficacy. Thus, we believe that internet use could be a new source of social support for the mothers of young children.

  • There are various types of energy simulation tool to predict both thermal load and energy use. However, the problem about these software is that they have too much input variables and need expert with skills to run the simulation. Therefore, the purpose of this study is to develop the thermal analysis simulation program with input variables which eliminates coordinates of building components instead of using full coordinates by using DOE2. Since the simulation engine of the program is DOE2, the validity of S-DOE is performed by comparing peak heating and cooling load results with VisualDOE and annual energy use results with actual energy use of 1996. The results have shown that there are little difference between VisualDOE and S-DOE. Also it showed that there are little difference between actual energy use and S-DOE energy use results. S-DOE took less time to model a building than VisualDOE. These results reveals that the application of S-DOE have potentials in accurately predicting both energy load and energy use of the building and still have an advantage of taking less time to model a building.

  • Purpose: This study aimed to investigate intensive care unit (ICU) nurses' actual and perceived glove uses for preventing healthcare associated infection. Methods: We observed nurses' donning glove by occasions and adherence to guideline for glove uses in four ICU in a single hospital. Total of 378 cases were observed from August 16 through October 6, 2020. Sixty one nurses of 66 nurses observed responded to a self-reported questionnaire about perceived glove use and knowledge of glove use. Data analysis was performed using descriptive statistics. Results: The number of observed episodes for glove use was 277. Although the highest numbers of occasions of wearing gloves was contact precaution, the compliance rate was 72.1%. The rates of donning gloves were low in the insertion and removal of peripheral venous catheters, blood glucose testing and blood sampling, which were at risk for exposure to blood. We observed misuse of wearing gloves even when they were not required. Results showed that the majority of non-compliance with glove use were a failure of performing hand hygiene before and after glove use and a failure of changing gloves between procedures on the same patient. The participant's knowledge of glove use was high. Conclusion: Based on the results, it is necessary to provide ICU nurses with education and reinforcement of proper glove uses for infection control.

  • With the current global need for eco-friendly energies, the large scale use of Electric Vehicles (EVs) is predicted. However, the need to frequently charge EVs to an electrical power system involves risks such as rapid increase of demand power. Therefore, in this paper, we propose a practical smart EV charging scheme considering a Time-of-Use (ToU) price to prevent the rapid increase of demand power and provide load leveling function. For a more practical analysis, we conduct simulations based on the actual distribution system and driving patterns in the Republic of Korea. Results show that the proposed method provides a proper load leveling function while preventing a rapid increase of demand power of the system.

  • The purpose of this study was to analyze biotope types of urban land-use patterns. Forest areas were considered according to vegetation type and potential for succession. Urban ecosystem structure was analyzed according to land use, land coverage, vegetation structure (actual vegetation, diameter at breast height, layer structure, and revetment). As a results of the classification, the biotopes were divided into 71 types according to the urban ecosystem structure. In the case of the Hanam province, the biotopes were divided into 51 types: 26 forest types; 5 swampy and grass land types; 3 farm land types; 3 types of planted land, and 8 types of urbanization.

  • Despite their potential value, the mobile Internet services in the domestic market have not been widely accepted as industry experts have expected. To understand why, this study uses the TAM, Technology Acceptance Model, and explores the factors affecting the usage behavior of the end-users. Based on statistical analysis of survey data, we show that social influence and perceived ease of use affect perceived usefulness, and that self-efficacy and focus significantly influence perceived ease of use. Furthermore, perceived usefulness is shown to play a significant role in explaining actual usage of the mobile Internet services. However, contrary to the hypothesized relationships, service quality, focus, and innovativeness of users turn out to have little impact on the traditional endogenous TAM variables such as perceived usefulness, perceived ease of use, and actual usage behavior. Based on these results, we attempt to provide managerial implications for the domestic mobile Internet service providers and to suggest future research directions in this domain of research.
