Due to the recent worldwide economic downturn, companies are required to put more effort into their innovation and quality improvement. In particular, business relationship is increasingly emphasized to be changed from a vertical relationship to a more horizontal relationship, such as collaborative partnership based on trust. In the logistics industry, through the collaboration, consignors can gain competitive advantages by focusing on their core capabilities, and freight forwarders also take advantages of securing stable cargoes and specialist expertise in distribution. Therefore, this study aims to identify key factors for developing a collaborative partnership between freight forwarders and consignors, and further examine the differences between the two groups empirically by using questionnaire survey. Based on the results, the main factors were found as follows: 1) Trust Building, 2) Competence Improvement, 3) Business Ecosystem and 4) Government Assistance. According to the analysis on sub-factors, first, among the four main factors, it turned out that trust is the most important variable. Specifically, the sub-factor of providing regular and stable service was revealed to be most critical. Second, it was found that forwarders need to improve services on 'Information Exchange System' and 'Electronic Data Interchange'. Finally, it is necessary for both consignors and forwarders to have better understanding of partnership. Key implications for both groups are highlighted based on the results.

Recently, the use of digital media such as computers and smart devices has been rapidly increasing, The vast and diverse information contained in the warrant of the investigating agency also includes the one irrelevant to the crime. Therefore, when confiscating the information, the basic rights, defense rights and privacy invasion of the person to be seized have been the center of criticism. Although the investigation agency guarantees the right to participate, it does not have specific guidelines, so they are various by the contexts and environments. In this process, the abuse of the participation right is detrimental to the speed and integrity of the investigation, and there is a side effect that the digital evidence might be destroyed by remote initialization. In this study, we conducted surveys of digital evidence analysts across the country based on four domains and thirty measurement items for enabling environment for participation in information storage media export and digital evidence search process. The difference between the level of importance and the performance was analyzed by the IPA matrix based on process, location, people, and technology dimensions. Seven items belonging to "concentrate here" area are one process-related, three location-related, and three people-related items. This study is meaningful to be a basis for establishing the proper policies and strategies for ensuring participation right, as well as for minimizing the side effects.

In July 2021, UNCTAD classified Korea as a developed country. After the Korean War in the 1950s, economic development was promoted despite difficult conditions, resulting in epoch-making national growth. However, in order to respond to the rapidly changing global economy, it is necessary to continuously study the domestic industrial ecosystem and prepare strategies for continuous change and growth. This study analyzed the industrial ecosystem of the automobile industry where it is possible to obtain transaction data between companies by applying complexity spatial network analysis. For data, 295 corporate data(node data) and 607 transaction data (link data) were used. As a result of checking the spatial distribution by geocoding the address of the company, the automobile industry-related companies were concentrated in the Seoul metropolitan area and the Southeastern(Dongnam) region. The node importance was measured through degree centrality, betweenness centrality, closeness centrality, and eigenvector centrality, and the network structure was confirmed by identifying density, distance, community detection, and assortativity and disassortivity. As a result, among the automakers, Hyundai Motor, Kia Motors, and GM Korea were included in the top 15 in 4 indicators of node centrality. In terms of company location, companies located in the Seoul metropolitan area were included in the top 15. In terms of company size, most of the large companies with more than 1,000 employees were included in the top 15 for degree centrality and betweenness centrality. Regarding closeness centrality and eigenvector centrality, most of the companies with 500 or less employees were included in the top 15, except for automakers. In the structure of the network, the density was 0.01390522 and the average distance was 3.422481. As a result of community detection using the fast greedy algorithm, 11 communities were finally derived.

In this article, an empirical study was conducted by using public dataset from Lending Club Corporation, the largest online peer-to-peer (P2P) lending in the world. We explore significant predictor variables related to P2P lending default that housing situation, length of employment, average current balance, debt-to-income ratio, loan amount, loan purpose, interest rate, public records, number of finance trades, total credit/credit limit, number of delinquent accounts, number of mortgage accounts, and number of bank card accounts are significant factors to loan funded successful on Lending Club platform. We developed online P2P lending default prediction models using discriminant analysis, logistic regression, neural networks, and decision trees (i.e., CART and C5.0) in order to predict P2P loan default. To verify the feasibility and effectiveness of P2P lending default prediction models, borrower loan data and credit data used in this study. Empirical results indicated that neural networks outperforms other classifiers such as discriminant analysis, logistic regression, CART, and C5.0. Neural networks always outperforms other classifiers in P2P loan default prediction.

온라인 채널의 발달로 전자상거래를 통한 거래와 수익 증가에 관한 많은 연구들이 진행되어왔으나 수익 원천으로써의 커뮤니티(Community)에 관한 연구는 제한적이다. Hagel(1997)은 커뮤니티를 미래 사업 모델의 중심축이 될 것으로 예측하고 커뮤니티의 수확체증효과와 수익증가역학고리, 커뮤니티 자산들을 통해 포탈 비즈니스 모델에 적합한 일방향적이고 순차적인 커뮤니티 형성 프로세스를 중심으로 제시하였다. 본 논문에서는 전자상거래의 형태에 따라 커뮤니티 형성 프로세스의 변화 형태는 차별화 된다는 사례들에 근거하여 e-비즈니스 모델에 따른 차별화 된 커뮤니티 성공요인, 커뮤니티 주요자산들의 중요도 차이, 전환비용발생 요인을 파악하였으며, 이를 바탕으로 커뮤니티 형성 프로세스의 구조적 변화 행태를 제시하였다. 본 연구는 온라인 비즈니스 도입 기업에게 비즈니스 모델과 연계하여 네트워크 외부 효과를 극대화하는 차별화 된 커뮤니티 활용 포커스와 수익성 향상을 위한 커뮤니티 형성 프로세스를 설계하는 프레임�p을 제시하였다는데 그 특징이 있다.

This study aims to classify the pursuit benefits of smart-phone users, to find smart-phone market segments by pursuit benefits, and to analyze the relative importances of smart-phone attributes according to the smart-phone market segments. As a result, we found that smart-phone users are pursuing the network benefit as well as the two traditional benefits (the utilitarian benefit and the hedonic benefit). According to the levels of these three pursuit benefits, smart-phone users can be classified into four segments : All Benefits Cluster, Utilitarian-Network Benefits Cluster, Hedonic-Network Benefits Cluster, and Non-Network Benefits Cluster. We also verified that, according to the four smart-phone user segments by the pursuit benefits, there exist significant differences in relative importances of the seven smart-phone attributes : hand-set price, hand-set brand, hand-set speed, applications, tariff, mobile internet quality, and number of same service users.

Increasing uncertainties in the technological innovation environment and increasing technology competition also present new challenges in terms of industrial technology security. Therefore, the purpose of this study was to identify the direction of policy change necessary for the improvement of related policies in the future by examining the importance and implementation of the government's industrial technology security support policies for small and medium-sized enterprises engaged in industrial technology innovation activities. As a result of the analysis, first of all, small and medium-sized enterprises that responded to the government's industrial technology security support policy were perceived to be less performing than the importance of the program. These results can be said to mean that selective budget expansion for related policy programs may be necessary, along with efforts to improve the quality of each program. Second, an analysis of the differences in group recognition between new technology certification firms and industrial technology verification(certification) companies showed that significant differences exist between groups for the program. These results suggest that more effective operation of the relevant policies may require policy enforcement in consideration of the level of security and will of each company in industrial technology, as much as the quantitative characteristics of the entity. This study is meaningful in providing the necessary policy directional basic information for the design and execution of more specific and effective industrial technology security policies by presenting empirical research results that domestic small and medium-sized enterprises are aware of about the government's industrial technology security policies.
