The purpose of this paper is to empirically analyze the effects of related and unrelated varieties of industry and occupation on regional economic growth. Recent studies dealing with the mechanism of economic growth argue that occupation as well as industry act as the driving force of regional economic growth by inducing knowledge externalities. Therefore, this study comprehensively analyzed the effects of occupational diversity along with industrial diversity. For the empirical analysis, we set the regional labor market areas as the spatial units of analysis. Dependent variables include regional per capita GRDP and employment growth between 2010 and 2015, and related and unrelated variety of industry and occupations measured based on the entropy approach are used as key explanatory variables. Our empirical results show that the related variety of industry has a positive effect on per capita GRDP in the region, and the related variety of occupation has a positive effect on regional employment growth. On the other hand, the unrelated variety of industries shows a negative correlation with regional employment growth. Based on the empirical results, this paper provides regional policy implications for strengthening economic vitality by dividing the diversity of industry and occupation into related and unrelated varieties and analyzing how they affect regional economic growth.

Along with the recent increase in national income, social phenomena such as aging due to a decrease in population and an increase in single households are observed. There are also an increasing number of households raising pets in proportion to aging households and the increase in the number of single households, most of which use animal companions to overcome loneliness and boost domestic vitality. As more and more people consider pets as family members, the size of the domestic pet market is also growing. The growing number of pets in older households and single households is not properly managed by care such as food meals and exercise management for pets. It is necessary to research and develop robots that can monitor animal companions remotely, feed a certain amount of food at regular intervals, and manage their health through exercise. Among pet companions, dog selection is the highest. Therefore, this study identified robot research on driving methods, examples of existing pet care systems, and researched pet care robots using obstacle avoidance algorithms. In order to use the snack pay behavior and obstacle avoidance algorithm of the pet animals by applying IoT and we .oPI technology, it is able to use ultrasonic sensors on the front and has four infrared sensors on the back. However, this study does not reflect the characteristics of other pet animals as a study on pet care robots, and it requires continuous observation and testing.

The aim of this study was to analyze dieting practices and tendencies in 2016 using big data. The keywords related to diet were collected from the portal site Naver and analyzed through simple frequency, N-gram, keyword network, and analysis of seasonality. The results showed that exercise had the highest frequency in simple frequency analysis. However, diet menu appeared most frequently in N-gram analysis. In addition, analysis of seasonality showed that the interest of subjects in diet increased steadily from February to July and peaked in October 2016. The monthly frequency of the keyword highfat diet was highest in October, because that showed the 'Low Carbohydrate High Fat' TV program. Although diet showed a certain pattern on a yearly basis, the emergence of new trendy diets in mass media also affects the pattern of diet. Therefore, it is considered that continuous monitoring and analysis of diet is needed rather than periodic monitoring.

This study analyzes China's technology billionaires. However, this study does not show the accumulating process of wealth in each of the Chinese billionaires, because there are many technology billionaires, but only deals with the macro analysis of the technology billionaire; the pattern of existence, comparison with other industries, the process of wealth creation reflecting China's particularity, and comparison with the world's technology billionaires. The findings of this study are as follows. First, more than 10 billion yuan of Chinese billionaires will emerge from 2004. Second, in the early days, illegal and corruption made rich, but the wealth of own efforts has gradually increased. Third, the real estate and manufacturing billionaires are still strong overall, but the growth of billionaires in technology, medicine and finance industry is remarkable. Fourth, in the case of the top 10 richest, four are from real estate, four from technology, and two from manufacturing and distribution. Most technology billionaires are in Guangdong, Zhejiang, Beijing and Shanghai. The determinants of the number of billionaires are GDP, exchange rate to US Dollar and Shenzen Stock Index, and those of technology billionaire are GDP and exchange rate. Given the relationship with existing theories, this study can be called the fifth type of billionaire research. Conceptually, the main reason for accumulating wealth is the search for policy opportunities, market opportunities and technology opportunities.

This study analyzes the technology billionaires with the combination of technology commercialization studies and billionaire research. However, we will not discuss individual billionaires, but discuss the general features of technology billionaires. This study assumes that the answers to the technology commercialization studies are in the technology billionaire researches. In other words, unlike the technology commercialization studies so far, it can be said that it is a retrospective approach of technology commercialization to see the process and the beginning from the result. The conclusion of this study is as follows. First, technology billionaires are in the middle rank among industries, but their wealth is the best. Second, in the technology sector, four 20s are self-made billionaires. It is a matter of securing technological opportunities, not a long training and preparation. Third, the determinants of technology billionaires are population size and venture capital investment. This means technological efforts and sufficient market conditions are the basis for the development of technology billionaires. Fourth, only high income is not the determinant of technology billionaires. There are many small countries that are very rich but can not utilize technology. Technology billionaires can appear in countries with a minimum of US $ 20,000, unless the country has a huge population such as China and India. Sixth, technology billionaires in the diversified business, classified as Chaebol in low-income countries become scarce in the countries over the US $ 40,000. Billionaires will increase rapidly from the mid-2000s. However, this is not explained by the income increase effect. The world's income increase has been slowing since the 1980s. The market economy effect of the socialist countries is not the reason, because it is limited to some socialist countries. Ultimately, the main reason is the new technology opportunity called the IT paradigm.

The study intends to identify the effects of infrastructure property on an apartment house by analyzing the price variation affected by factors constituting the quality of the transit services of each individual station in urban railway system based on hedonic price model. The research findings indicate that the prices depending on the transit users have increased from 7.8% to 12.2% in Seoul and decreased from 6.1% to 12.9% in Gyeonggi, which implies that a lower number of transfer users has a positive effect on housing prices in Seoul unlike Gyeonggi. It also is noteworthy that the distance to the urban railway station had a negative effect on housing prices in Seoul and positive effect in Gyeonggi. Taking these results together, in Seoul, the increase in the number of transit users had a negative effect on neighborhood housing prices. When analyzed by segments, however, an additional negative effect was observed only in the apartments located within the radius of 100 meters. It is also found that the impact of transit users varies according to the regional characteristics, such as the density of commercial facilities and the population density, and the spatial extent of negative effect also showed regional differences. These results provide implications for the planning of new stations, new cities, and land use of existing areas around stations.

The survey conducted with 120 florists in Korean domestic flower shops to investigate the use and awareness of floral preservatives in Korea. As a result, only 19.8% of the domestic florists use floral preservatives frequently in their shops, whereas 45.5% do not use them at all, suggesting very low use frequency. Korean domestic florists considered the use of floral preservatives mostly for storing cut flowers to preventing bacteria growth. For the reasons not to use floral preservatives, 51.4% of the Korean domestic florists did not value its usefulness, showing a lack of awareness of floral preservatives. However, 44.2% of the florists who had the experience with floral preservatives satisfied with the effect of floral preservatives, and 49.5% of the respondents positively answered to recommend floral preservatives to others. General awareness on floral preservatives among Korean domestic florists was positive. 50.5% of the florists with the experience with the floral preservative had the high intention to re-purchase the flower preservatives. The low use frequency and lack of recognition of floral preservatives in Korea were likely due to very few floral preservative brands and little advertising. However, the high satisfaction level and repurchase intention rate shown by the florists indicates that increasing advertising and education for the floral preservatives would improve the accessibility and awareness of the products and their effects increasing the opportunity to use floral preservatives among Korean domestic florists, further enhancing consumers' satisfaction by improving the cut flower quality and its vase life.
