Objective: The objective of this study was to investigate undergraduate student's attitudes toward person with disabilities. Design: Questionnaire-based study Methods: This study conducted a survey of 350 undergraduate students attending two universities in cities B and C from March to April 2024. Out of a total of 350 questionnaires, 334 questionnaires were analyzed after excluding 16 questionnaires due to incomplete content. The questionnaire was revised and enhanced by the researchers and was supplemented through revision and verification by another occupational therapist as professor. Results: As a result of the study, significant differences in undergraduate students' positive attitudes toward the disabled were found to be gender and taking disability-related curriculum, while significant differences in negative attitudes were found to be gender, presence of a disabled person in the family, and religion. Gender, taking disability-related curriculum, and religion showed significant differences in neutral attitude, and in all areas, gender, taking disability-related subjects, having a family member with a disability, and religion showed significant differences. Conclusions: Factors that influence undergraduate students' attitudes toward person with disabilities include gender, whether or not they take disability-related curriculum, whether a family member is disabled, and religion. As our society's policies and perceptions of person with disabilities are rapidly changing, in order to improve our society's attitude and awareness of disabilities, we need to provide students with a correct understanding of disabilities and develop positive attitudes through positive experiences about disabilities. Educational programs should be provided.

In recent years, the development of digital design methods and structural analysis has made it possible to design complex building shapes. However, the construction of such buildings requires advanced knowledge of production, interaction with actual craftsmen, and verification of construction methods through mock-ups. Despite this, however, design education in Japanese universities is often limited to proposals at the predesign and schematic design stages, and students have few opportunities to study the design development and construction stages. However, in recent years, computer numerical control (CNC) machine tools have become relatively inexpensive and can be handled easily, even by beginners. Therefore, practical training programs intended to familiarize students with manufacturing techniques using such machines are becoming increasingly popular at Japanese universities. This paper reports on the content of a practical training program intended to provide students with practical experience from production to design in the field of manufacturing by using CNC machine tools and other digital fabrication equipment to create a mock-up of a complex curved surface for a building and simulate the process of construction production in the design development and construction management. It is difficult to create curved surfaces using only digital fabrication, and manual processes, such as bending wooden boards along curved surfaces, are required. Therefore, students were required to combine digital fabrication knowledge with hands-on manufacturing skills, including hand-bending and experiential learning, which helped students think about the necessary processes for constructing the shapes they designed.

Despite the gradual growth of mobile markets according to an increased mobile distribution rate, empirical studies on the mobile shopping application markets are not sufficient. From the viewpoint of a large number of purchase of brand product in department store by customers and a high growth rate of mobile shopping by means of mobile shopping, we classified a principle variable, the interactivity, into three levels and verified the effects of the interactivity on the flow, effects of the flow on the purchase intention and the control effect of purchase level. In conclusion, among the three levels of the interactivity the customer-customer interactivity and the content-customer interactivity have positive effects on the flow, but company-customer has not. On the other hand, the customer-customer interactivity and the content-customer interactivity have a positive effect on the flow. Furthermore, the flow affects the purchase intention positively. After the verification of the direct effect of interactivity on the purchase intention, the content-customer interactivity only has a positive effect on the purchase intention. Lastly, the purchase level has a control effect when the customer-customer interactivity has a positive effect on the flow.

This study was to verify and calibrate seven kinds of soil water sensors for volumetric soil water content(VSWC) measurement under field. Types of sensors were TDR (Time Domain Reflectometry) and FDR(Frequency Domain Reflectometry). Two kinds of TDR were TRIME(profile type), and Mini-TRASE(rod type). Five kinds of FDR were EasyAG, EnviroSCAN, PR-1(profile type), and WET-1(rod type). VSWC by TRIME and Mini-TRASE compared with VSWC by soil core showed the standard error of about 2.4%, and 1.4% which is the smallest value among all the sensors used in the experiment, respectively. The errors of EasyAG and EnviroSCAN analyzed with scaled frequency(SF) were about 2.6%, and 2.8% and those by 1 versus 1 correspondence were about 2.6%, and 2.6%, respectively. WET-1 showed about 2.0% of error, which is the smallest value among errors by FDR sensors. PR-1 with the error of about 4.7% should be hard for application in field. Therefore, users on soil water sensors have to take into consideration the errors of sensors revealed after the calibration for the correct measurement of VSWC in field. The rest except for PR-1 among the sensors could be used for VSWC measurement with 1.4~2.6% error.

This study was conducted to find out the optimal extraction conditions to obtain extracts with a high content of ginsenosides and antioxidant activity using the ginseng berry. After extraction by stirring, ultrasound and microwave method using 70% ethanol and distilled water as solvents, the results of considering the content of ginsenoside Re and Rb1, total polyphenol content, antioxidant activity, and whether it is an environmentally friendly manufacturing method, it was confirmed that the microwave method using distilled water is good method of extraction. The optimization of extraction conditions for microwave method were made by response surface methodology (RSM). Microwave power (50 ~ 200 W, X1), solvent and ginseng berry ratio (5 ~ 20 times, X2) and the extraction time (30 ~ 120 s, X3) were used as independent variables. The model showed a good fit having a determination coefficient of the regression equation of 0.9 or more and a p-value less than 0.05. Estimated conditions for the maximized extraction of ginsenoside contents and total polyphenols were 200 w in microwave power, 20 times in solvent and ginseng berry ratio, and 90 s in extraction time. Predicted values at the optimum conditions were total polyphenols of 6.23 mg GAE/g, ginsenoside Re of 17.69 mg/g, and ginsenoside Rb1 of 16.01 mg/g. In the verification of the actual measurement the obtained values showed 6.33 mg GAE/g, 17.79 mg/g, and 15.59 mg/g, respectively, in good agreement with predicted values.

In this study, the correlation between recycled plastic pellets and the antioxidant efficacy of the extract of Mucuna pruriens (M. pruriens) was verified. After immersing recycled plastic pellets in M. pruriens extracts, they were stored for 30 days under various temperature conditions, and then analyzed for DPPH radical and ABTS⁺ radical erasing ability, SOD-like activity, total phenol and flavonoid content. Compared to the existing efficacy, DPPH radical elimination showed less than 30% activity change in ECOTRIA and PCR-PP pellets, and the largest decrease in activity of 46.06% was confirmed in Grico pellets. As a result of measuring ABTS⁺ radical erasure ability, less than 5% of efficacy change was confirmed in all pellets. As a result of measuring SOD-like activity, all showed a decrease in activity of more than 30%, and as a result of measuring the total phenol and flavonoid content, all pellets showed a tendency to decrease compared to the existing content. Through this results, it was confirmed that the physiological activity of M. pruriens extract decreased and changed by recycled plastic pellets, and based on the results of this study, recycled plastic pellets are believed to affect the existing efficacy and activity stability of M. pruriens extract.

In this study, the shear wave velocity of the ground was measured using Flat TDR, and the precision analysis of the measured value and the verification of field applicability were performed. The shear wave velocity measurement value was derived in the field using the piezo-stack combined in the Flat TDR. analyzed. As a result of the experiment, the average value of the change in shear wave speed at the time of grout material injection was 10.15 m/s at the beginning of age, and the average value of the change in shear wave speed after the 7th to 14th days was 65.99 m/s, showing a tendency to increase with age. Also, it was found that dry density and shear wave speed increased as the water content increased on the dry side, and that the dry density and shear wave rate decreased as the water content increased on the wet side as the water content increased. The shear modulus value derived from the field test was confirmed to be a minimum of 17.36 MPa and a maximum of 28.13 MPa, confirming a measurement value similar to the reference value. Through this, it can be seen that the measured value of the shear modulus using Flat TDR is reliable data, and it can be determined that the compaction management of the site can be effectively managed in the future.
