Recently, the platform industry is rapidly growing in the global market, and competition is intensifying at the same time. Therefore, in order for domestic platform companies to have global competitiveness in the platform market, it is necessary to study the platform business ecosystem and success factors. However, most of the recent platform-related studies have been theoretical studies on the characteristics of platform business status analysis, platform economy, and indirect network externalities of platforms. Therefore, this study comprehensively analyzed the success factors of Silicon Valley's business ecosystem proposed in previous studies, and at the same time analyzed the success factors extracted from stakeholders in the actual Silicon Valley platform business ecosystem. And based on these factors, an IPA analysis was conducted as a way to propose a success plan to stakeholders in the platform business ecosystem. As a result of the analysis, among the success factors collected through previous studies, manpower, capital, and challenge culture were identified as factors that are relatively well maintained in both importance and satisfaction in Silicon Valley. In the end, it can be seen that the creation of an environment and culture in which Silicon Valley can use it to challenge itself based on excellent human resources and abundant capital contributes the most to the success of Silicon Valley's platform business. On the other hand, although it is of high importance to Silicon Valley's platform corporate ecosystem, the factors that show relatively low satisfaction among stakeholders are 'learning and benchmarking among active companies' and 'strong ties and cooperation between members', and it is analyzed that interest and effort are needed to strengthen these factors in the future. Finally, the systems and policies necessary for market autonomous competition, 'business support service industry', 'name value', and 'spin-off start-up' were important factors in literature research, but the importance and satisfaction of these factors were lowered due to changes in the times and environment. This study has academic implications in that it comprehensively analyzes the success factors of Silicon Valley's business ecosystem proposed in previous studies, and at the same time analyzes the success factors extracted from stakeholders in the actual Silicon Valley platform business ecosystem. In addition, there is another academic implications that importance and satisfaction were simultaneously examined through IPA analysis based on these various extracted factors. As for academic implications, it is meaningful in that it contributed to the formation of the domestic platform ecosystem by providing the government and companies with concrete information on the success factors of the platform business ecosystem and the theoretical grounds for the growth of domestic platform businesses.

The purpose of this study is to identify potential semantic landscape makeup of "the Forty Eight Poems of Soswaewon" according to Yin-Yang and Five Elements Principle(陰陽五行論). that speculation system between human's nature and cosmical universal order. Existing academic discussions made so far concerning this topic can be summed up as follows: 1. Among Yin-Yang-based landscape makeups of the Forty Eight Poems of Soswaewon, poetic writings for embodiment of interactions between nature and human behaviors focused on depicting dynamic aspects of a poetic narrator when he appreciates or explores hills and streams as of to live free from worldly cares. Primarily, many of those writings were created on the east and south primarily through assignment of yang. On the other hand, poetic writings for embodiment of nature and seasonal scenery - as static landscape makeup of yin - were often created on or near the north and west for many times. Those writings focusing on embodiment of nature and artificial scenery as a work are divided into two categories: One category refers to author Kim In-hu's expression of semantic landscape from seasonal scenery in nature. The other refers to his depiction of realistic garden images as they are. In the Forty Eight Poems of Soswaewon, the poetic writings show that author Kim focused on embodying seasonal scenery rather than expressing human behaviors. In addition, both Poem No. 1 and Poem No. 48(last poem; titled 'Jangwon Jeyeong') were created in a same place, which author Kim sought to understand the place as a space of beginning and end where yin and yang - i.e. the principle of natural cycle - are inherent. 2. According to construction about landscape in the Forty Eight Poems of Soswaewon on the basis of Ohaeng-ron (five natural element principle), it was found that tree(木) and fire(火) are typical examples of a world combined by emanation. First, many of poetic writings depicting the sentiments of tree focused on embodying seasonal scenery and were located in the place of Ogogmun(五曲門) area in the east, from overall perspective of Soswaewon. The content of these poems shows generation and curve / straightness in flexibility and simplicity. Many of poems depicting the sentiments of fire(火) focused on embodying human behaviors, and they were created in Aeyangdan area on the south of Soswaewon over which sun rises at noon. These poems are all on a status of side movement that is characterized by emanation and ascension which belong to attributes of yang. 3. With regard to Ohaeng-ron's interpretation about landscape in the Forty Eight Poems of Soswaewon, it was found that metal(金) and water(水) are typical examples of world combined by convergence. First, it was found that all of poems depicting sentiments of metal focused on embodying seasonal scenery, and were created in a bamboo grove area on the west from overall perspective of Soswaewon. They represent scenery of autumn among 4 seasons to symbolize faithfulness vested in a man of virtue(seonbi) with integrity and righteousness. Poems depicting sentiments of water were created in vicinity of Jewoldang on the north, possibly topmost of Soswaewon. They were divided into two categories: One category refers to poems embodying actions of welcoming the first full moon deep in the night after sunset, and the other refers to poems embodying natural scenery of snowscape. All of those poems focused on expressing any atmosphere of turning into yin via convergence. 4. With regard to Ohaeng-ron's interpretation of landscape in the Forty Eight Poems of Soswaewon, it was found that poems depicting sentiments of earth(土), a complex body of convergence and emanation, were created in vicinity of mountain stream around Gwangpunggak which is located in the center of Soswaewon. These poems focused on carrying actions of author Kim by way of natural phenomena and artificial scenery.

The purpose of this study was to investigate the effectiveness of integrated education research conducted in Korea and to propose a meaningful discussion for further research. Among the studies conducted for last three years, the relevant 161 research articles were selected, and 236 effect sizes were calculated. Effect sizes were analyzed with different dependant variables including creativity, problem solving ability, academic achievement, inquiry skills, creative personality, scientific attitude, and interests. In addition, effect sizes with different moderating variables, such as characteristics of subjects, sample sizes, class types, core disciplines and publication types, were compared. The results are as follows: The overall effect size of integrated education program produced a huge effect (effect size=0.88, U3=81.06%). Integrated education program showed the highest effect size on scientific attitude among other dependant variables. However, all of the other dependant variables represented more than medium size effect size. Integrated program proved to be more effective on kindergarten pupils and gifted students compared to other school levels and regular students. The effect size for group of less then thirty students were larger than other groups. Programs implemented in after school hours were more effective than in regular school hours. Considering the core subject of program, arts-centered integrated programs showed the largest effect size, while all the others showed above medium effect sizes.

This study analyzed current use of 2-block haircut styles and preferences for accurate understanding of the haircut and enhancement of its efficiency. For this, a questionnaire survey was performed against 441 men in their 20~40s living in Jeollanam-do from June 27 to July 6, 2019. A total of 430 copies were used for final analysis. The collected data were analyzed by frequency analysis and cross-tabulation analysis, using SPSS 21.0, and the results found the followings: When asked about the factors affecting their choice of the haircut, 58.4% (20~40s in age) responded, 'my own decision'. Second, 61.2% said that they were interested in a 2-block haircut, and 54.7% responded that they had the haircut before. Among them, 92.3% said that they were satisfied with the trendy undercut. The above results confirm that men's appearance management is now essential, considering changes in social environments. People envision their hairstyle and visit a hair salon based on their own will, not after recommendation from their acquaintances. Many customers prefer a 2-block haircut because they believe it looks good on them. In addition, they choose the easy-to-care undercut to have a clean and neat image. It is anticipated that the study results would make a contribution to suggesting basic academic data and enhancing sales in a 2-lock haircut which is expected to remain popular. Therefore, it proposes in-depth studies on new 2-block haircut styles for women.

The purpose of this study is to examine the current status of automobile logistics in the domestic automobile industry and to derive and evaluate the factors to improve the quality of automobile logistic services to final consumers. To that end, we selected the relevant factors through literature review and expert interviews, and conducted a survey with consumers and experts. The quality of automobile logistic service was evaluated using the Importance-Performance Analysis (IPA) method. The results show that the "kindness of shipping staff" is high on the importance of customers but low on the importance of employees. On the other hand, factors that have high customer satisfaction but low staff satisfaction include "rapid handling of complaints", "transportation accuracy of receipt", "kindness of delivery staff", and "automobile manual guide and explanation of internal functions". This study has academic and industrial significance in that it has derived important factors for evaluating the quality of automobile logistics services and suggests improvement measures for experts and consumers who actually work in the industrial field. Future research should investigate measures to minimize the returns and complaints of shipment offices which have not been examined in this study.

In this paper, we propose an effective software education scheme for universities. The key idea of this software education scheme is to analyze software curriculum of QS world university rankings Top 10, SW-oriented university, and regional main national university. And based on the results, we propose five improvements for the effective SW education method of universities. The first is to enhance the adaptability of the industry by developing courses based on the SW developer's job analysis in the curriculum development process. Second, it is necessary to strengthen the curriculum of the 4th industrial revolution core technologies(cloud computing, big data, virtual/augmented reality, Internet of things, etc.) and integrate them with various fields such as medical, bio, sensor, human, and cognitive science. Third, programming language education should be included in software convergence course after basic syntax education to implement projects in various fields. In addition, the curriculum for developing system programming developers and back-end developers should be strengthened rather than application program developers. Fourth, it offers opportunities to participate in industrial projects by reinforcing courses such as capstone design and comprehensive design, which enables product-based self-directed learning. Fifth, it is necessary to develop university-specific curriculum based on local industry by reinforcing internship or industry-academic program that can acquire skills in local industry field.
