This study is about online purchases of foods that have been reluctant to deal with distribution processes and reliability issues. We find out that attributes of the online food market affects behavior intention and whether it differs according to consumption tendency. A survey was conducted on consumers who had ever purchased food online for hypothesis testing. Reliability and feasibility were reviewed for the collected data and the hypothesis was verified through structural equation model analysis. While product diversity, product information and customer service factors of the online food market significantly affect behavior intention, price is not. We identified differences in the impact of behavior intention on consumption tendencies. For the Gaseongbi group, only the product information factors have significant effect on behavior, and for the Gasimbi group, the price and customer service factors have a significant effect on behavior intention. The findings provide theoretical and practical implications for marketers to study various marketing method based on consumer tendencies.

While green packaging related concerns are mainly studied in developed countries, there is a lack of knowledge to observe purchase behavior toward green packaging in developing countries, especially in Vietnam. Buying green packaged products in FMCG is not required to trade-off between sustainability and product performance. Hence, this present research aims to understand the gap attitude - behavior existing on FMCG green packaged products among Vietnamese young consumers with psychosocial factors (environmental concern, environmental knowledge of green packaging and green trust) and contextual factors (availability of desired green packaging and product attributes). With a sample size of 396 respondents, data was collected by convenient sampling method and then was analyzed using structural equation modeling. The results reveal that all psychosocial factors are positive related to attitudes while purchase behavior is positively influenced. The findings also report that contextual factors have positive impacts on purchase behavior, which proves the important role of contextual factors in influencing consumer choices. It suggests that green packaging is receptive to Vietnamese young consumers but it should be considered within product-related context to enhance the difference in sustainability among similar FMCG products. Practical implications for marketers and future researches have also been discussed at the end of study.

Most companies are achieving economic benefits by producing products in the form of bi-national products, but there are also negative consequences such as reduced brand power, so strategic bi-national product planning and branding is essential. In order to actively reflect these practical needs, this study conducted a comprehensive and easy-to-generalize evaluation of Bi-national products that has been somewhat underdeveloped in previous studies. To this end, the selection and evaluation criteria of the products to be investigated were differentiated. This is to classify the products by place of use and the purpose of use so that the majority of bi-national products can be included, and then use the combination to derive the specific products to be evaluated for bi-national products. The evaluation of the product identified the phenomenon of psychological conflict among consumers due to the country of origin discrepancy at the level of decreasing brand authenticity. The above research design is an evaluation method that can encompass bi-national products as a whole, rather than an evaluation of a specific product or product line that is mainly reported in previous studies, and it is also very easy to apply to practice because it allows us to more carefully identify changes in psychological attitudes.

This work tries to empirically validate the effect of influencers' product-usage videos upon brand attitude and purchase intention of consumers. More specifically, we choose 3 attributes of product-usage videos of influencers such as expertise, trustworthiness, and attractiveness from our literature review. We collect 200 survey questionnaires in 2019 using Google survey forms from subjects who have watched influencers' usage videos of fashion items. Our results suggest that expertise and trustworthiness of influencers' videos positively affect brand attitude of consumers, which in turn positively influence their purchase intention. However, we have not found significant effect of attractiveness of the videos upon brand attitude. We also confirm that brand attitude positively affect purchase intention as proposed in the literature. The practical implications of this work is that firms should focus and strengthen expertise and trustworthiness of videos rather than attractiveness in order to enhance purchase intention of consumers and eventually lead to their purchase behavior.

In metal forming, there are problems with recurrent geometric characteristics without explicitly prescibed boundary conditions. In such problems, so-called recurrent boundary conditions must be introduced. In this paper, as a practical application of the proposed method, the precision cold forging of a helical gear has been simulated by a three-dimensional rigid-plastic finite element method and compared with the experiment. The application of recurrent boundary conditions to helical gear forging analysis is proved to be effective and valid. the elastic stress analysis of the die for helical gear forging has been calculated by using the nodal force at the final stage obtained from the rigid-plastic finite element analysis. In order to obtain more precise gear products, the elastic analysis of the die after release of punch and the elastic spring-back analysis of product after ejection have been performed, and the final dimension of the computational product has been in good agreement with that of the experimental product.

In this thesis, an optical bidirectional inner-product associative memory model using liquid crystal television is proposed and analyzed theoretically and realized experimentally. The LCTV is used as a SLM(spatial light modulator), which is more practical than conventional SLMs, to produce image vector in terms of computer and CCD camera. Memory and input vectors are recorded into each LCTV through the video input connectors of it by using the image board. Two multi-focus hololenses are constructed in order to perform optical inner-product process. In forward process, the analog values of inner-products are measured by photodetectors and are converted to digital values which are enable to control the weighting values of the stored vectors by changing the gray levels of the pixels of the LCTV. In backward process, changed stored vectors are used to produce output image vector which is used again for input vector after thresholding. After some iterations, one of the stored vectors is retrieved which is most similar to input vector in other words, has the nearest hamming distance. The experimental results show that the proposed inner-product associative memory model can be realized optically and coincide well with the computer simulation.

In room acoustics, reverberation time is an important acoustic parameter. However it is often difficult to measure short reverberation times at low frequencies with a traditional band pass filter bank if the product of filter bandwidth (B) and reverberation time (T) is small. It it well known that the minimum permissible product of bandwidth and reverberation time of the traditional band pass filter is at least 16. This strict requirement makes it difficult to measure short reverberation times of an acoustic room at low frequencies exactly. In order to reduce this strict requirement, in the previous paper, the wavelet filter bank was developed and the minimum permissible product of bandwidth and reverberation time was replaced with 4. In the present paper it is demonstrated how the short reverberation times of an practical room at low frequencies are successfully measured by using the wavelet filter bank and the results are compared with the traditional method using a band past filer bank.

A Bayesian analysis for the product of different powers of k independent Poisson rates, written ${\theta}$, is developed. This is done by considering a prior for ${\theta}$ that satisfies the differential equation due to Tibshirani and induces a proper posterior distribution. The Gibbs sampling procedure utilizing the rejection method is suggested for the posterior inference of ${\theta}$. The procedure is straightforward to specify distributionally and to implement computationally, with output readily adapted for required inference summaries. A salient feature of the procedure is that it provides a unified method for inferencing ${\theta}$ with any type of powers, and hence it solves all the existing problems (in inferencing ${\theta}$) simultaneously in a completely satisfactory way, at least within the Bayesian framework. In two examples, practical applications of the procedure is described.

Company strategy that considers market trend becomes a more important key to success in the new product development. Well-being as a present social trend has created a huge new product market. but with increasing number of camouflaged well-being products that are not fulfilled consumer needs. The purpose of this study is to understand the concept of well-being products from a consumer point of view an to find five consumer values based on the consumer value model of Sheth, Newman, and Gross(1991) through conducting content analysis from semi-structured individual In-depth Interviews. This study has a significance in identifying the detailed consumer value attributes and influence factors by collecting practical and reach qualitative data in the lack of systematic research of domestic well-being market and its products from a consumer point of view. The result of this study will be a foundation of future quantitative researches and provide a guideline to companys' well-being marketing strategy.
