Interest in bodybuilding, such as weight training, has increased, but research on the motivation and behavioral intention of college students is lacking. Therefore, this study aimed to examine the motives of bodybuilding participation for college students and to find out the effect on behavioral intention by mediating the psychological resistance that occurs during the bodybuilding. As for the research method, a questionnaire was conducted on 250 users through an online survey from May 30 to June 10, 2023, and a total of 232 copies were used for the final analysis. As a result of the study, first, among college students' motivation to participate in weight training, the health-oriented type and self-development type had a positive effect on voluntary acceptance. Second, among the motives for participating in weight training, the home-oriented type was found to have a negative effect on opportunistic acceptance. Finally, voluntary acceptance had a positive effect on learning outcomes, and opportunistic acceptance had a negative effect on learning outcomes. Using the results of this study, it is expected that it will be helpful to understand the factors and policies in promoting the physical health of college students.

In this study, we analyzed causal relationships between technology orientation and technological performance, between technological performance and commercialization speed on the government -funded R&D projects in 2009 for searching the cause of the big gap between technological success rate and commercialization success rate. In the result, technology orientation affected negatively on the technological performance, but the technological performance affected positively on the commercialization speed. These results mean that low technology oriented projects are easy to reach the selling step of products faster but they are not easy to attain a balanced income and outgo in contrast to the firms' own R&D. we found it was caused by a defect in the government's R&D support and management system.

The present paper describes a method of recognizing a polyhedron employing the notion of network constraint analysis. Typical difficulties in three-dimensional object recognition, other than shading, reflection, and hidden line problems, include the case where appearances of an object vary according to observation points and the case where an object to be recognized is occluded by other objects placed in its front, resulting in incomplete information on the object shape. These difficulties can, however, be solved to a large extent, by taking account of certain local constraints defined on a polyhedral shape. The present paper assumes a model-based vision employing an appearance-oriented model of a polyhedron which is provided by placing it at the origin of a large sphere and observing it from various positions on the surface of the sphere. The model is actually represented by the sets of adjacent faces pairs of the polyhedron observed from those positions. Since the shape of a projected face gives constraint to that of its adjacent face, this results in a local constraint relation between these faces. Each projected face of an unknown polyhedron on an acquired image is examined its match with those faces in the model, producing network constraint relations between faces in the image and faces in the model. Taking adjacency of faces into consideration, these network constraint relations are analyzed. And if the analysis finally provides a solution telling existence of one to one match of the faces between the unknown polyhedron and the model, the unknown polyhedron is understood to be one of those memorized models placed in a certain posture. In the performed experiment, a polyhedron was observed from 320 regularly arranged points on a sphere to provide its appearance model and a polyhedron with arbitrarily postured, occluded, or imposed another difficulty was successfully recognized.

PMN-PZT films with thickness of $5\;{\mu}m$ were deposited on $Pt/Ti/SiO_2/Si$ substrate at room temperature using aerosol deposition process. The films showed fairly dense microstructure without any crack. XRD and TEM analysis revealed that the films consisted of randomly oriented nanocrystalline and amorphous phases. Post-annealing process was employed to induce crystallization and grain growth of the as-deposited films and to improve the electrical properties. The annealed film showed markedly improved electrical properties in comparison with as-deposited film. The film after annealing at $700^{\circ}C$ for 1h exhibited the best electrical properties. Dielectric constant $(\varepsilon_r)$, remanent polarization $(P_r)$ and piezoelectric constant $(d_{33})$ were 1050, $13\;{\mu}C/cm^2$ and 120 pC/N, respectively.

When automatic speech recognition (ASR) is provided as a cloud service, it is easy to collect voice and application domain data from users. Harnessing these data will facilitate the provision of more personalized services. In this paper, we demonstrate our transfer learning-based knowledge service that built with the user-generated data collected through our novel system that deliveries personalized ASR service. First, we discuss the motivation, challenges, and prospects of building up such a knowledge-based service-oriented system. Second, we present a Quadruple Transfer Learning (QTL) method that can learn a classification model from a source domain and transfer it to a target domain. Third, we provide an overview architecture of our novel system that collects voice data from mobile users, labels the data via crowdsourcing, utilises these collected user-generated data to train different machine learning models, and delivers the personalised real-time cloud services. Finally, we use the E-Book data collected from our system to train classification models and apply them in the smart TV domain, and the experimental results show that our QTL method is effective in two classification tasks, which confirms that the knowledge transfer provides a value-added service for the upper-layer mobile applications in different domains.

The study was focused on setting priority for future core technologies in crops using Analytic Hierarchy Process (ARP). The technologies were derived by Delphi method. Evaluation criteria for the priority setting were decided as 'technology', 'market oriented', and 'public concerns' by council. The future core technologies were divided as four groups by importance and R&D level. Technologies in upper two groups were considered in the study. Group I had high importance and high R&D level. Group II had high importance and lower R&D level. Questionnaires were given to 8 specialists in crops. As the results, 'public concerns' was decided as the most important evaluation criterion. The most important technologies are 'developing of growing technology that has low inputs and production cost for environmental friendly agriculture' in group I, and 'developing of gene searching, characteristics transformation, and commercialization technologies for crops using bio-technology' in group II.

This study examined the contents of 'Adolescent's Consumption Life' unit in 12 Technology Home Economics textbooks used in the 2009 revised curriculum to analyze the contents of school consumer education. The main summary of this study is as follows: First, the contents of consumer education in the unit of 'Adolescent's Consumption Life' consisted of five criteria including the understanding of adolescent consumer, consumer's right and responsibility, reasonable purchase, resolution to consumer problems, and the formation of new consumption culture. Second, significant differences were found in the contents of consumer education among textbooks because basic concepts have been not been clearly defined yet. Third, essential content was either omitted or hard to understand. Thus, some contents elaborations were inappropriate for students' level. Fourth, there were some limitations in drawing interest and attention from learners and developing dispute resolution competence, since the textbooks mainly comprised the theory-oriented contents of consumer education. Fifth, cautious consideration needs to be taken with regards to clear understanding of basic concepts and systematic and consistent contents composition for coherent and organized school consumer education. These research findings are anticipated to provide basic information of Technology Home Economics textbooks to teachers, and will be utilized as basic data in organizing textbook contents or developing efficient teaching-learning programs for consumer education.

Purpose - The study aimed to evaluate the market opportunities and constraints confronting resource-poor pig farmers in South Africa. Research design, data, and methodology - Information was collected from 292 households in three municipalities through interviews with key informants. The data collected included socio-economic characteristics, major market channels, prices for different pig classes, average weight of the pigs on sale, number of pigs sold annually, and preferred meat quality attributes. Results - In Ngqushwa, 96% of respondents sold pigs as compared to Elundini (81%) and Ntabankulu (65%). Less resource-poor households and those with market-oriented production had large herdsizes (P < 0.05) when compared to more resource-poor farmers. The probability of selling pigs was high for the backyard production system and educated farmers. For all farmers, opportunities included high pork demand, good prices, employment creation, and a niche market for organically produced indigenous pork. Constraints include disease, feed shortages for large herds, distances to formal markets, lack of training, and drugs. Conclusions - Constraints outnumbered opportunities for the resource-poor pig farmers.
