This research was aimed to extend the vase life and improve the quality of cut roses 'Marina'. This study investigated the effect of three different angles and sucrose concentration on the vase life and the quality of cut rose flowers. In first experiment, cut roses were placed in three different angles ($0^{\circ}$, $45^{\circ}$ and $90^{\circ}$) in holding solutions containing 0.5, 1 and 2% sucrose (soaking treatment), and examined the number of petals of cut roses. In second experiment, cut roses were placed in three different angles after pre-treated in 0, 1, 2 and 4% sucrose solution for 2 and 20 hours, and examined the flower diameter of cut roses. In third experiment, cut roses were examined the pigmentation, flowing response and chlorophyll contents in cut roses by three different angles after pulsing treatment (pre-treatment) in holding solution containing 2% sucrose for 2 and 20 hours. Results of this study showed that cut roses were influenced by arranging angles and sucrose concentrations. The vase life of cut roses were extended in $45^{\circ}$ and $90^{\circ}$ arranging angle, as compared with the control (distilled water), and the holding solution containing 2% sucrose significantly increased vase life of cut roses(P < 0.05). Flower diameter of cut roses pre-treated in 4% sucrose solution for 2 and 20 hours significantly decreased (P < 0.05). The pigmentation and flowing response in cut roses were beneficial in $45^{\circ}$ arranging angle treated with 2% sucrose solution for 2 and 20 hours. Chlorophyll content in leaves of cut roses was not influenced by arranging angles. The pigmentation and flowing response of $0^{\circ}$ and $45^{\circ}$ arranging angles were better than that of 90 arranging angle. The vase life of cut roses in $45^{\circ}$ arranging angle was more prolonged than that in $90^{\circ}$ arranging angle. In conclusion, the arranging angles seem to be effective in retarding senescence of cut rose flowers.

The dramatic rise of experience space using cultural heritage in modern architecture has been generally acknowledged in recent literature. The present study aims to investigate effective ways to enhance competitiveness in local experience space, with an emphasis on the use of cultural heritage in modern architecture. Using the case of the Sam-Rae Arts Village in Wanju-gun, Jeollabuk, this study analyzes the characteristics of the 4Es in experience economy theory. In order to arrive at findings that represent the variety of perspectives found in this context, qualitative interviews were conducted with three groups: public officials, maintenance staff in the experience center, and field experts. The results of this study revealed that the Visual Media Art Museum and Book Wooks were used for entertainment, the Corpentry Shop for education, the Book Museum for escapism, and the Design Museum Culture $Caf{\acute{e}}$ The O's for aestheticism. Additionally, depending on the commercial potential of the respective experience space, the Corpentry Shop, Book Wooks, and the Culture $Caf{\acute{e}}$ The O's were used for profit purposes while the Design Museum and the Visual Media Art Museum for non-profit. Based on the findings of the present study, effective ways to enhance competitiveness in the local experience space are suggested. First, the public nature of cultural enjoyment may be realized in a field that bears non-profit characteristics. In exhibiting works, the experience space could suggest the extra demonstration. Second, in the for-profit experience hall, the securing of tourists may help to maximize profit. In so doing, a variety of experience programs and activity spaces could be provided internally, while advertisement marketing through mobile and SNS could be reinforced externally.

Using the United Nations Convention on the Rights of the Child(UNCRC) as a frame of reference, this study examined South and North Korean children's rights as reported in the UNCRC and the pattern of changes in the reports depending on the period in which the reports were written. For this purpose, we reviewed Article 1 of the Convention to see what age range the South and North Korean governments, respectively, specify to define a child. We also analyzed the method and attitude of how each Korean government acknowledges the rights of children in the four general principles of the Convention("non-discrimination", "the best interests of the child", "the right to life, survival, and development" and "respect for the views of the child"). The results showed that there was asymmetric content between South and North Korea in the four general principles of the Convention. Both South and North Korea lack a sense of respect for the views of children. There were also differences in the rights of children depending on the distinct characteristics of each Korea. In South Korea, it is important to guarantee the rights of multicultural children and provide a plan for child safety. On the other hand, North Korea has emphasized that they provide the necessities of life and free education to children. Both Koreas have continuously submitted their reports and showed improvement in understanding the rights of children in each report. We conclude that it is essential for South and North Korea to build common ground in their respective contents on children and to establish a foundation of normative standards in the path to prepare for reunification. Moreover, we also conclude that South and North Korea should work collaboratively to reach mutual consent to achieve these goals.

This paper aims to apply our research and theorization on arts entrepreneurship to entrepreneurs active in the arts and cultural sector. Our goal is to develop proposals for practical actions that can support both arts entrepreneurs and supportive arts advocates. Using Action Research methodology, we hosted and facilitated two workshops with selected groups of arts entrepreneurs. Prior to the workshops we designed a questionnaire, based on the competency theory, to assess the qualities and characteristics of the participants. During the workshops we conducted surveys, interviews, and made observations in order to further understand the knowledge, experiences, motivations, capabilities, and attitudes necessary to successful arts entrepreneurship. We also conducted in-depth follow-up interviews with participants as a cross-check. We found that most of the participating arts entrepreneurs had a low understanding of the technology required for effective arts entrepreneurship, which has resulted in insufficient managerial support for artistic innovation. In addition, we found that participants lacked the skills and clear vision to construct a viable economic engine for their organization. Nevertheless, in light of the considerable strengths and high levels of enthusiasm and commitment participants evinced, we believe that their deficits can be corrected with education and training. Thus, we conclude by discussing the path forward and outlining a proposal to develop an innovative educational program on the daily operations of arts management that emphasizes applied technology and creating financial sustainability.

This study examines demand of the Korean TV VOD using monthly aggregate data and time series analysis models. In particular, the impact of box office attendance, number of IPTV subscribers, income and price of substitutes on TV VOD market is analyzed. Data on TV VOD download during the period 2013 January to 2018 June are used for the empirical analysis. TV VOD demand shows lower level of seasonality than box office attendance and the share of monthly top1 movie in TV VOD platform is also lower than that of box office attendance. The relationship between a movie's holdback and box office performance does not seem consistent. The empirical result of ARDL model reveals that in the short-run box office attendance, number of IPTV subscribers and price of substitutes have significant impact on TV VOD demand. The result on the long-term relation shows that income is the only determinant of TV VOD demand. The impact of box office attendance on TV VOD is not shown to be robust both for the short-term and long-term.

This study was examined the characteristics on the pollinating activities of Apis mellifera, Bombus ignitus and B. terrestris as pollinators on the watermelon flowers(Citrullus vulgaris Schrad), and the effects of the pollination by pollinators compared to the artificial pollination in the watermelon green houses in Nonsan City on summer season in 2005. As a result, B. ignitus and B. terrestris could not be used for summer season, because the bumblebees were not pollinated effectively indeed even two days after hives were released at watermelon green houses during the summer cultivating period. It could not be controlled a poor watermelon house conditions; high temperature and low humidity on summer season which were the bad environment for pollinating activities of bumblebees. But this study was showed that A. mellifera could be used comparatively good pollinator instead of artificial pollination in spite of the bad environment for bee within the watermelon green houses on summer season.

Purpose: The franchise system started by Singer Sewing Machine in the US is acting as a national economic growth engine in terms of job creation and economic growth. In China, the franchise system was introduced in the mid-1980s. And since joining the WTO, it has grown by 5-6% every year. However, compared to the growth rate of franchises, studies on shared growth between the chain headquarters and franchisees were insufficient. Accordingly, recent studies related to shared growth between the chain headquarters and franchisees have been active in China. The purpose of this study is to examine the knowledge transfer system between the knowledge creation, knowledge sharing, and the use of knowledge by franchise chain headquarters in China. In addition, the relationship between franchise satisfaction and performance is identified. Research design, data, and methodology: The data were collected from franchise stores in Sichuan, China, and were conducted with the help of ○○ Incubation, a Sichuan Province-certified incubator. From November 2020 to January 2021, 350 copies of the questionnaire were distributed in China, and 264 copies were returned. Of these, 44 copies with insincere answers and response errors were excluded, and 222 copies were used for analysis. The data were analyzed with SPSS 22.0 and AMOS 22.0 statistical packages. Result: The results of this study are as follows. First, knowledge creation has been shown to have a statistically significant impact on knowledge sharing and knowledge utilization. In particular, the effectiveness of knowledge creation was higher in knowledge sharing than in knowledge utilization. And we can see that knowledge sharing also has a statistically significant e ffect on knowledge utilization. Second, knowledge sharing was not significant for transaction satisfaction and business performance, and knowledge utilization was significant for transaction satisfaction and business performance. These results can be said to mean less interdependence of the Chinese franchise system. Finally, transaction satisfaction was statistically significant to business performance. The purpose of this study was to examine the importance of knowledge management to secure long-term competitive advantage for Chinese franchises. This study shows that knowledge sharing is important for long-term franchise growth. And we can see that there is a lack of knowledge sharing methods in the case of franchises in China. I n addition, it was found that the growth of Chinese franchises requires systematization of communication, information sharing measures and timing, help from chain headquarters, and mutual responsibility awareness.

Objectives: We aimed to examine the association between the relative preference for vegetables and meat and cancer incidence, in a population-based retrospective cohort in Korea. Methods: We included 10,148,131 participants (5,794,124 men; 4,354,007 women) who underwent national health screening between 2004 and 2005 from the National Health Information Database of the National Health Insurance Service (NHIS-NHID). Participants were asked whether they preferred consuming 1) vegetables more often, 2) both vegetables and meat or 3) meat more often. Participants were followed up to Dec. 31, 2017. All cancer and eighteen common cancer cases were identified through the code from the International Classification of Diseases, 10th revision. We estimated sex-specific relative risks and 95% confidence intervals, adjusting for age, body mass index, alcohol consumption, smoking, physical activity, and income level. Results: During an average follow-up of 12.4 years, 714,170 cancer cases were documented. In men, consuming meat more often was associated with lower risk of esophageal, liver, and stomach cancers, but higher risk of lung and kidney cancers. Consuming both vegetables and meat was associated with higher risk of prostate cancer, but with lower risk of esophageal, liver, and stomach cancers in men. In women, consuming meat more often was associated with a higher risk of colorectal cancer and breast, endometrial, and cervical cancers diagnosed before the age of 50. Consuming both vegetables and meat was associated with lower risk of liver cancer in women. Conclusions: Our study suggests a potential link between vegetable and meat intake and cancer incidence in the Korean population. Further investigation on the association between the intake of specific types of vegetables and meat and cancer risk in Korean prospective cohort studies is needed.
