Using youth panel data, this study attempted to diagnose the effect of residential characteristics (housing type and housing type) and various household background variables on the implementation of youth NEET (Not in Employment, Education or Training), and to suggest appropriate policy directions. As a result of the analysis, it was found that young individuals residing in unfavorable living conditions such as those who rent on a monthly basis or live in multi-household, villa, or officetel settings, had a higher likelihood of transitioning to NEET. Those who received financial support from their parents were more likely to transition to NEET. Therefore, comprehensive youth NEET support policies such as customized housing and job policies according to the characteristics of NEET should be established. In particular, even though they have reached adulthood, it is shown that the likelihood of becoming NEET is very high for youth who live together with their parents without being economically independent or who receive financial assistance from their parents. In order to mitigate and prevent these young people from NEET transition, transitioning from school to the labor market should be facilitated with policy support.

In the past, purchasing limited products was nothing more than purchasing expensive luxury goods. However, the current 'Limited product purchase' is not just pay to ability, but the information to purchase the product are important factors. Therefore, this study aims to find out 1) the motivation to purchase limited edition products and 2) the effect of the motivation on the consumer's experience(price, intention to purchase). As a result, five major purchase motives(Conformity, Interest, Scarcity, Finance technology, Desire to concede) were found. Among them 'Interest' had a positive effect on the product purchase price, and 'Conformity' had a negative effect on the product price. Next, 'Interest' and 'Scarcity' had a positively significant effect on intention to purchase. Through this study, we were able to reveal in depth the actual purchase motives of consumers who are currently emerging as the main age group of the new consumption culture, and expect these purchase motives to be actively used in the new market such as resell markets.

This study analyzed bidding data for construction projects ordered by the Public Procurement Service under the lowest bidding system since 2001 by using statistical technique in terms of construction types, company sizes, bidding prices. This study brings out construction company's bidding practices and problems caused by the current lowest bidding system and suggests the way to mitigate the problems and to improve the lowest bidding system. The analysis shows the problem of winning a bid in abnormally low price under the lowest bidding system, feared at the start, was realized. As bidding practice has polarized with low and high price, the analysis shows that the lowest bid system's market has a high possibility to be distorted by construction companies' bid strategies. To complement the lowest bidding system's problem, the analysis shows that introduction of the bidding system using particulars where bidders estimate construction quantities and unit prices by themselves is needed.

Smart Farm means creating new value in various fields related to agriculture, including not only agricultural production but also distribution and consumption through the convergence of agriculture and ICT. In Korea, a rental smart farm is created to spread smart agriculture, and a smart farm big data platform is established to promote data collection and utilization. It is pushing for digital transformation of agricultural products distribution from production areas to consumption areas, such as expanding smart APCs, operating online exchanges, and digitizing wholesale market transaction information. As such, although agricultural data is generated according to characteristics from various sources, it is only used as a service using statistics and standardized data. This is because there are limitations due to distributed data collection from agriculture to production, distribution, and consumption, and it is difficult to collect and process various types of data from various sources. Therefore, in this paper, we analyze the current state of domestic agricultural data collection and sharing for digital agriculture and propose a data collection and linkage method for artificial intelligence services. And, using the proposed data, we propose a deep learning-based environmental factor recommendation method.

도시하천은 급속한 경제성장과 개발 등 여건변화에 따라 크게 변화되어왔다. 이에 하천은 본연의 모습과 가치를 잃고 인공적인 모습으로 변해 하천의 주요 기능인 자정작용, 생태계 건강성 유지 등의 기능을 잃고 도시 활동에 따른 오염물질에 노출되어가고 있는 실정이다. 이로 인한 부정적인 영향으로 도시민의 삶의 질과 만족도 또한 하락되고 있다. 본 연구에서는 부산의 대표하천인 수영강을 대상으로 도시하천 수질 개선을 위한 도시민의 지불의사를 추정하였다. 비시장가치를 추정하기 위해 조건부가치측정법(CVM, Contingent Valuation Method)을 적용하여 수질개선에 따른 지불의사(WTP, Willingness To Pay)를 파악하고 경제적 가치를 추정하였다. 가상시나리오는 EPA, water quality ladder의 개념을 이용하여 현재 수영강 수질이 오염된 물(4등급)이라고 가상시장을 설정하고 낚시가 가능한 수준(2등급)까지 개선을 시키고자 할 때의 지불의사를 물었다. 이때 지불수단은 기부금의 형태로 연 1회 향후 5년간 지불기간을 설정하였다. WTP 모형추정은 KDI에서 제시하고 있는 로지스틱분포 함수와 스파이크 모형을 사용하여 WTP를 추정하였다. 스파이크 모형의 추정결과 평균 지불의사액은 12,255원으로 부산광역시 전체 가구 수인 1,392,291가구(2019년)에 적용할 경우 향후 5년간 연 170억 원의 재원을 확보할 수 있는 것으로 나타났다. 지불의사 추정결과 수영강 인접 지역주민의 지불의사가 높게 추정되었고, 부산시민이 수영강을 자연과 생태보전 기능하천으로 인지하고 있음(56.5%)을 고려 할 때, 하천환경개선을 통한 지불의사의 상승은 도시하천 가치 향상이 될 수 있을 것으로 판단된다. 또한 도시민의 기대수준 충족과 더불어 도시하천 가치상승을 위한 부족한 재원까지도 조달 할 수 있는 방안의 기초를 마련 할 수 있을 것이라 판단된다.

The position of newspaper has been getting critical, since there are various new digital devices that can embody much information in only one device. Smart devices has risen the possible replacement of newspaper, while they are getting lighter and getting faster access to the information. However, there is lack of study on the application for smart devices, since it is at the early stage of development. In this study, the design method for the effective news application is considered by analyzing not only an external element, the layout design, but also an internal element, the content of it. Then, 20 domestic and foreign news applications were analyzed concentrating on the layout and the contents. Through the observation, I looked into what type of applications that can be deliver messages effectively. After the observation, participants are asked about their impressions and preferences of the applications. A news application for smart devices should not be just a mobile version of newspaper. If so, a news application never be able to leap over authority and popularity of the newspaper. So, it needs constant researches on an effective news application focused on the attribute of the smart devices to develop the news application for the devices.

The development of IT increases the importance of understanding of IT-driven ecosystems. Platform business is the representative business model in the era of innovative IT-based businesses. However, it lacks the review research that entails ecosystem perspectives from traditional disciplines in which the perspective of ecosystem had been applied. Further most of platform research have focused on the comparison between ecosystems as a whole rather than exploration on complementors in the ecosystem who are selected and survive and, in turn, contributed to maintain the ecosystem to compete with other ecosystems. The current study listed highly cited papers from economics, sociological ecology, socio-technical ecology, organization studies, and marketing research which have cumulated research on ecosystems. And the three most critical features that determine the success of complementors, which are competition, relationality, and adaptability. Present study showed how the features were explained by each perspective from the different disciplines.

The sharing economy has emerged as a new form of consumption pattern along with the advancement of information technology and the changes in the consumers' desires for economic spending. In a C2C-sharing economy platform, the user side and supplier side share the same assets, thereby making both sides of the market closely related. However, an information asymmetry exists within the platform that makes the players from one side reluctant to participate. This information asymmetry warrants a strategic approach for solving the fundamental "chicken and egg" problem for platform development. Motivated by this phenomenon, this study aims to analyze how the participation intentions from both sides of the platform are influenced by certain anteceding factors, such as trust, perceived risk, and perceived economic profit. Our findings show that the anteceding factors affect the participation intentions in different paths for both sides of the platform. As a managerial implication, these findings highlight the necessity of employing different approaches for each side of market development.

In Korea, the permission for private investigation(PI) industry was implemented in 2020, and many PI associations and education institutions are currently training private investigators in the form of private qualifications. In line with the expansion of PI industry, universities are also establishing and operating private investigation study departments or major courses, and are constantly developing research and programs to provide education that meets the purpose and characteristics. This study compared and analyzed the subjects of various domestic universities that already operate the detective department and suggested the direction necessary for the development of PI market in Korea and the revival of private investigation studies in the future. The contents of the study include the composition of an educational model reflecting the field, the expansion of professors specializing in PI studies, and the development of original subjects in PI studies that break away from subjects such as police science and criminology. It is hoped that suggested direction will be actively reflected to lay the foundation for the development of private investigation studies and private investigation industry.
