Extant literature has emphasized the role of citizen participation in creating a successful smart city. However, previous works are lacking in a systematic analysis of the specific mechanisms by which citizen participation makes a positive impact on smart city projects. We attempt to bridge the gap by focusing on the role of the living lab, a citizen-driven mechanism that has used innovative ideas, new technologies, and cooperation with various participants to address local problems. As co-creation is the common ground for smart cities and living labs in terms of citizen participation, we provide a theoretical framework in which the notion of co-creation mediates smart cities and living labs. To examine the living lab's effect of co-creation on smart cities, we conduct a comparative case study of two Northeast Asian cities: Taipei and Busan. We explore (1) the factors behind the different outcomes in these two cities, despite many similarities that might affect smart cities' effectiveness, and (2) the relationship between smart cities and living labs and how to systematically understand the interaction between the two. We find that living labs have played a key role in making Taipei's smart city projects effective and successful, which allows the city to keep showing a high level of performance. In contrast, citizens could not find channels to participate in such projects in Busan. We conclude that the living lab explains why the smart cities in Busan have been less successful than in Taipei.

As society evolves, people are making more of an effort to learn more about human aspects, one of which is emotional intelligence, a topic on which education experts have traditionally concentrated. This is due to the fact that emotional intelligence has a significant impact on how people think and manage their emotions. On the other side, it promotes the development of expressive ability and aids people in better adapting to life. This study explores the relationship between communication skills, leadership skills, stress management, adaptability, and emotional intelligence of FPT University students to determine the factors that affect students' emotional intelligence. To survey 500 FPT University students, this study used a sample size of 500. Previous studies used a 5-point Likert scale to assess the four skill elements. According to the results, students who completed the survey showed adequate communication skills, leadership qualities, stress management, adaptability, and emotional intelligence. Emotional intelligence is influenced by communication skills, leadership abilities, stress management, and flexibility. This suggests that students who master these four skills have higher levels of emotional intelligence. The outcomes of this study reveal that students have been conscious of Emotional Intelligence since a young age. The affirmations in this research paper will benefit students and young people interested in enhancing complimentary soft skills that boost Emotional Intelligence.

The smart farm is a remarkable system because it utilizes information and communication technologies in agriculture to bring high productivity and excellent qualities of crops. It automatically measures the growth environment of the crops and accumulates huge amounts of environmental information in real time growing in smart farms using multi-variable control of environmental factors. The statistical model using the collected big data will be helpful for decision making in order to control optimal growth environment of crops in smart farms. Using data collected from a smart farm of tomato, we carried out multiple regression analysis to determine the relationship between yield and environmental factors and to predict yield of tomato. In this study, appropriate parameter modification was made for environmental factors considering tomato growth. Using these new factors, we fit the model and derived the optimal environmental factors that affect the yields of tomato. Based on this, we could predict the yields of tomato. It is expected that growth environment can be controlled to improve tomato productivities by using statistical model.

Since the Industrial Revolution, which made the mass production and mass distribution of standardized goods possible, machine-made (manufactured) products have accounted for the majority of the market. However, in recent years, the phenomenon of purchasing even more expensive handmade products has become a noticeable trend as consumers have started to acknowledge the value of handmade products, such as the craftsman's commitment, belief in their quality and scarcity, and the sense of self-esteem from having them,. Consumer interest in these handmade products has shown explosive growth and has been coupled with the recent development of three-dimensional (3D) printing technologies. Etsy.com is the world's largest online handmade platform. It is no different from any other online platform; it provides an online market where buyers and sellers virtually meet to share information and transact business. However, Etsy.com is different in that shops within this platform only deal with handmade products in a variety of categories, ranging from jewelry to toys. Since its establishment in 2005, despite being limited to handmade products, Etsy.com has enjoyed rapid growth in membership, transaction volume, and revenue. Most recently in April 2015, it raised funds through an initial public offering (IPO) of more than 1.8 billion USD, which demonstrates the huge potential of online handmade platforms. After the success of Etsy.com, various types of online handmade platforms such as Handmade at Amazon, ArtFire, DaWanda, and Craft is ART have emerged and are now competing with each other, at the same time, which has increased the size of the market. According to Deloitte's 2015 holiday survey on which types of gifts the respondents plan to buy during the holiday season, about 16% of U.S. consumers chose "homemade or craft items (e.g., Etsy purchase)," which was the same rate as those for the computer game and shoes categories. This indicates that consumer interests in online handmade platforms will continue to rise in the future. However, this high interest in the market for handmade products and their platforms has not yet led to academic research. Most extant studies have only focused on machine-made products and intelligent services for them. This indicates a lack of studies on handmade products and their intelligent services on virtual platforms. Therefore, this study used signaling theory and prior research on the effects of sellers' characteristics on their performance (e.g., total sales and price premiums) in the buyer-seller relationship to identify the key influencing e-Image factors (e.g., reputation, size, information sharing, and length of relationship). Then, their impacts on the performance of shops within the online handmade platform were empirically examined; the dataset was collected from Etsy.com through the application of web harvesting technology. The results from the structural equation modeling revealed that the reputation, size, and information sharing have significant effects on the total sales, while the reputation and length of relationship influence price premiums. This study extended the online platform research into online handmade platform research by identifying key influencing e-Image factors on within-platform shop's total sales and price premiums based on signaling theory and then performed a statistical investigation. These findings are expected to be a stepping stone for future studies on intelligent online handmade services as well as handmade products themselves. Furthermore, the findings of the study provide online handmade platform operators with practical guidelines on how to implement intelligent online handmade services. They should also help shop managers build their marketing strategies in a more specific and effective manner by suggesting key influencing e-Image factors. The results of this study should contribute to the vitalization of intelligent online handmade services by providing clues on how to maximize within-platform shops' total sales and price premiums.

The visual humor can be regarded as an original source for creative ideation. There are several types of humor. for example,'wit, satire, irony and so on. These can be motivations of developing an up-to-date idea. Wit differs from most humor in being purely intellectual, rather than relying on incongruities that come up naturally in many situations. The humor of words contains pun, hyperbole, repetition, and comparison or contrast. Especially in case of pun, it can be most important type of humor for making analytical and humorous effects visually. Pun, meaning the humor of double meaning, furnish us with much of our humor. The concept of pun is the most valuable for creating the visual humor by substituting, combining and manipulating symbols. There are essentially three distinct categories of puns : the literal pun, the suggestive pun, and the comparative pun. All types of puns belong to one of these three groups. The definitions are simple to understand and easy to apply for creating the visual humor, In order to develop a better conceptual model, (this researcher) reexamine the concept of humor, the relationship of humor to various types of message processing, and the relationship of humor to various aspects of message. This thesis. is primarily concerned with basic theories of humor such as concepts of humor, types of humor and analysis of humor. And this contains the research of humor's communications effects and theory of humor response with literature reviews. Modem theories of humor response generally fall into three major schools : Incongruity theories, Superiority theories and Arousal (Relief theories. Together these three approaches address the cognitive-perceptual, affective-evaluative and psycho-dynamic dimensions of a subject's humor response. The literature research of humor and humor response theory in communications and visual communications can help the visual application of humor concepts and usefulness of visual humor appeals. This research agreed that the humor and visual humor must be very effective at being as a means for the advertising expression, not for the purpose itself. In addition, this research is aimed at studying significations and usefulness of visual humor through semiotic approaches in the near future. Then it can be essencial research for the appropriate situational uses of humor related to media, product, and audience factors, such as nationality, age, standard of living, sexuality, and so on.

According to Plato's ontology, we lead our lives by establishing a relationship with others in the society. However in rapidly changing era, our lives was gradually moving towards personal tendency. Even for the relationship with family, not with others. Thus, awareness about owning properties has changed due to the sociocultural factors and increase number of single-person households. So in this study, the considerations for single-person housing were perceived through preceding research, and the elements making spatial boundary of shared housing were drawn to make rational space sharing based on the boundary with others and of the living environment. With overall analysis based on the spatial boundary features of planned shared housing, the plan characteristics according to the spatial boundary of the current shared housing is to be drawn and analyzed. Third, The expressive and structural features of spatial boundary as above appear with mutual flexible connectivity, And the result shows that the modularity was the highest. Among them variable coupling modularity of shows how it is possible to combine efficiently and variously the private and public spaces with regularity of 'space of optimal unit'. This study drew plan characteristics from more detailed space border of shared housing. Therefore, The basic framework of the characteristics spin for the cases that newly emerge later on.

The Collaborative Filtering (CF) is one of the popular techniques for personalization in e-commerce storefronts. For CF-based recommendation, every customer needs to provide subjective evaluation ratings for some products based on his/her preference. Also, if an e-commerce site recommends a new product, some customers should rate it. However, there is no in-depth investigation on the impacts on recommendation performance of two number of ratings, i.e. the number of ratings of an individual customer and the number of ratings of an item, even though these are important factors to determine performance of CF methods. In this study, using publicly available EachMovie data set, we empirically investigate the relationships between the two number of ratings and the performance of CF. For the purpose, three analyses were executed. The first and second analyses were performed to investigate the relationship between the number of ratings of a particular customer and the recommendation performance of CF. In the third analysis, we investigate the relationship between the number of ratings on a particular item and the recommendation performance of CF. From these experiments, we can find that there are thresholds in terms of the number of ratings below which the recommendation performances increase monotonically. That is, the number of ratings of a customer and the number of ratings on an item are critical to the recommendation performance of CF when the number of ratings is less than the thresholds, but the value of the ratings decreases after the numbers of ratings pass the thresholds. The results of the experiments provide insight to making operational decisions concerning collaborative filtering in practice.

A Study of the Emotionality of Child and Mother The purpose of this study is primarily to understand the emotional climate of child and mother, which is a significant factor in child study and the home life. A sample was collected from a total of 1,592 of whom 796 are elementary school children with their mothers. Of these 796 children 440 are fom private schools, 190 from public schools in Seoul. The rest are taken from a farming area, 100 kilometers from Seoul. The data was basically obtained through answers to a questionaire distributed in September 1973. In this study, the cross-sectional method, percentage calculation and chi-square test are adapted from factor analysis. With this limited amount of data special attention now, the following conclusions can be drawn from this analysis although special attention should be given in making any kind of generalization about the entire population. 1) Children's emotionality (a) There is a higher percentage of emotionally well-adjusted children as opposed to maladjusted children.(51%>11%) (b) There is no correlation between children's emotionality and the following factors: grade, sex, residential area, school records, and educational level of their mothers. 2) Mother's Emotionality (a) There are more mothers who consider themselves happy than unhappy.(49%>2%) On the other hand a higher percentage of mothers reported feelings of tension and insecurity as compared to those who had feelings of firm security(65%>5%) (b) There is a high correlationshionship between marital adjustment and marital happiness. In other words, the more adjusted, the happier. A high marital happiness has strong influence on the preference of sex, on children's adjustment to their friends, and their present living condition. (c) There is a close relationship between a high marital adjustment and the social development of a child: being fond of fathers, homelife, and the acquaintance with many friends. In the same way, the positive emotionality of a mother in raising her children and their school records are also important. 3) Emotional relationship between a mother and her chid There is a close bond of love and respect between a mother and her child.
