Under the global economic system, farmers are developing various sales channels in addition to traditional sales channels due to continuous changes in the market environment and consumer behavior. As a result, many farmers have started direct marketing, and the government is implementing policies to support direct transactions to secure farm income. The purpose of this study is to identify factors affecting the selection of sales channels such as wholesale, farmsite sales, and store sales of mulberry fruit farmers using a multinomial logit model, and to present basic data for a difference in revenues by sales channel. As a result of analyzing the factors influencing the selection of sales channels of mulberry fruit farmers, it was found that the number of family members, the presence of successors, and the size of the mulberry fields have more impact than demographic characteristics such as the age and farming experience of farm owners. In addition, as a result of comparing the revenues of mulberry fruit farms by sales channel, it was found that farms with store sales as their main sales channel earned statistically significantly more revenues than farms with farm sales as their main sales channel. Based on these results, there were some suggestions for selection of sales channel for mulberry fruit farms.

Over the past few years, companies have started moving into specific niches in plus-size fashion. The purpose of this study was to verify the marketability of young plus-size clothes in the USA. Data were collected from female consumers aged from 20 to 39 who have experience of purchasing plus-size items. A total of 282 responses were used for statistical analysis. The research result is as follows. First, the obesity stress is affected more by the subjective obesity level than by the objective obesity level and by how people recognize their body types. Second, from an analysis of the factors affecting the shopping orientation of plus-size consumers, style consciousness, pursuing reasonable, emphasizing comfort, and body consciousness are found to be important factors. Third, even if responders are aware of their exact body size, they actively look for the correct size. Fourth, fit evaluation of plus-size products is based on the factors of size fit and movement fit. The respondents were unsatisfied with chest and arm measurements, which deviate widely by body type for tops. Fifth, the overall dissatisfaction with the plus-size market is attributed to the fact that the product assortment range from which to select styles is narrow, and trend reflection is low. Sixth, the respondents tended to avoid fabrics that make their body type more obvious, textures that give the impression of a larger body size, or stiff textures. These results show that the psychological and physical characteristics of obese consumers should be considered to develop products for the young plus-size market.

The key issue of block-based multi-focus image fusion is to determine the size of the sub-block because different sizes of the sub-block will lead to different fusion effects. To solve this problem, this paper presents a novel genetic algorithm (GA) based multi-focus image fusion method, in which the block size can be automatically found. In our method, the Sum-modified-Laplacian (SML) is selected as an evaluation criterion to measure the clarity of the image sub-block, and the edge information retention is employed to calculate the fitness of each individual. Then, through the selection, crossover and mutation procedures of the GA, we can obtain the optimal solution for the sub-block, which is finally used to fuse the images. Experimental results show that the proposed method outperforms the traditional methods, including the average, gradient pyramid, discrete wavelet transform (DWT), shift invariant DWT (SIDWT) and two existing GA-based methods in terms of both the visual subjective evaluation and the objective evaluation.

Purpose: This study focuses on the Chinese smartphone market to estimate product attributes influencing Chinese customers' preference for developing new smartphones through conjoint analysis. Research design, data and methodology: The online questionnaire survey is processed among Chinese potential smartphone customers. Conjoint analysis including traditional conjoint analysis (TCA) and choice-based conjoint analysis (CBCA), is used to analyze the useful data of 500. Results: Results indicate that price is the most important predictor while screen size is the least for Chinese customers' preference whether the method is TCA or CBCA. However, the importance of brand, capacity, CPU, and screen design is different. Moreover, based on each smartphone attribute level's utility, the new products with the best combinations are different compared with both methods. Finally, the predicted market shares of the top 3 products are the same with maximum utility rule model between TCA and CBCA. However, when considering with the new best combined product, they are significantly different. Conclusions: Managers should recognize the differences between TCA and CBCA and select the best method to develop new smartphones for sustainable business in the Chinese competitive market based on the important attributes of price, brand, capacity, CPU, screen design, and size.

It is very useful and important to see the status and change of necessary parts in a short period through selecting and observing the bioindicator continually to forecast and prepare the future. Especially, living things are so closely related to the environment that the indicator between the environment and living things shows close interrelationship. Also, the indicator related to environment provides information about representative or decisive environmental phenomenon and is used to simplify complicated facts. Considering wide range of background and application including various indicators such as the change-, destruction-, pollution-, and restoration of habitats, climate change, and species diversity, the closest category includes "environmental indicator," "ecological indicator," and "biodiversity indicator." The selection and use of bioindicator is complicated and difficult. The necessary conditions for the indicator selection are flexible and greatly depend on the goals of investigation such as the indicator for biological diversity investigation of specific area, the indicator for habitat destruction, the indicator for climate change, and the indicator for polluted area. It should meet many various conditions to select a good indicator. In this study, eleven selection standards are established based on domestic and overseas studies on bioindicator selection: species with clear classification and ecology, species distributed in geographically widespread area, species that show clear habitat characteristics, species that can provide early warning for a change, species that are easy and economically benefited for the investigation, species that have many independent individual groups and that is not greatly affected by the size of individual groups, species that is thought to represent the response of other species, species that represent the ecology change caused by the pressure of human influence, species for which researches on climate change have been done, species that is easy to observe, appears for a long time and forms a group with many individuals, and species that are important socially, economically, and culturally.
