Platform lending or online lending, sometimes called peer-to-peer (P2P) lending, arose due to the digital revolution to meet people's requirements for simple fund borrowing. It quickly became an alternative to other traditional lending techniques, for example, loans banks. Along with the growth of P2P lending, several academics have investigated how information technology is used in financial services, emphasizing extended application methods. This study proposes an enhanced technology acceptance model (TAM) that investigates how consumers embrace P2P lending platforms by using quality of service and perceived risk as drivers of trust, relative advantage and compatibility as drivers of perceived usefulness. For the purpose of this study, we created a questionnaire, distributed it to clients of P2P lending platforms and fintech services in general in cities in Java, Indonesia. We received 290 replies to our questionnaire. The data was analyzed to test the hypotheses using structural equation modeling (SEM). The findings show that consumers' trust, relative advantage, perceived usefulness, and perceived ease of use in P2P lending platforms substantially affect their views toward adoption. The research's findings are useful for fine-tuning platform marketing strategies and putting strategic goals into action.

일찍이 복지국가 발달에 산업화가 중요한 영향을 끼친다는 산업화 이론은 복지국가 발달을 설명하는 주요한 이론으로 자리매김해 왔다. 그러나 산업화 이론은 산업화가 발달한 서구 선진국가들이라 하더라도 공공복지의 규모는 상대적으로 약하다는 비판에 직면하였고, 이러한 한계를 보완, 설명하기 위해 이익집단들이 선거 경쟁에서 승리하기 위한 전략으로 공공부문의 복지가 확대될 수 있었다는 민주주의 이론, 복지국가를 요구하는 노조와 좌파정당들의 힘이 강화될 때, 복지국가 또한 발달할 수 있었다는 권력자원 이론 등이 부각되었다. 본 연구는 복지국가 발달을 설명하기 위한 새로운 시도로서 복지국가의 발달에 영향을 주는 기존 이론들에 따른 요인들 외에 산업구조에 따른 요인들을 추가하여 퍼지셋 질적비교 분석을 수행하였다. 분석결과 복지국가발달에 있어 기존이론 외에 제조업의 비중 또한 복지국가 발전의 중요 요소로서 작용할 수 있다는 점을 발견할 수 있었다. 이러한 분석결과는 산업화 이론, 민주주의와 선거경쟁이론, 권력자원 등과 같은 복지국가를 설명하는 기존이론 뿐만 아니라 제조업 비중과 같은 산업구조 또한 복지국가 발달에 영향을 줄 수 있는 요소임을 시사하고 있다.

Fashion industry is faced with issues of raising the competitiveness of established designers recently. As well as the change of business system, the specialization of professionals in design team increases the needs of in-service training of fashion designers. But, the education programs of enterprise are generally focused on adaptability to the organization and harmony among men as an introduction level. Furthermore, there are few professional institutions that give an education to the working-level designers. Thus, this study aimed at development of specialized in-service training program that could educate established designers for more integrated thought to cope with rapid changes in the fashion field. Firstly, the theoretical study on the in-service training and changes of fashion environment had been studied through literature review. Then, the current state of in-service training of fashion enterprises and the courses for established designers in fashion institutions were analysed. Finally, a comprehensive framework of in-service training program for fashion designers has been established as a result of this study. The program was designed in accordance with the previous research which reached 4 different educational needs for in-service training: brand planning and management, understanding production, understanding practical fabrics & colors, computer program. The study went further to apply the program to each design group divided by career: new designer, junior designer, senior designer, design leader. This study also suggested evaluation process to confirm the effects.

In this paper, the Packet CDMA Reservation ALOHA protocol is proposed to support the multi-traffic services such as voice and videophone services with handoff calls, high-rate data and low-rate data services efficiently on the multi-rate transmission in uplink cellular systems. The frame structure, composed of the access slot and the transmission slot, and the proposed access permission probability based on the estimated number of contending users for each service are presented to reduce MAI. The assured priority to the voice and the videophone handoff calls is given through higher access permission probability. And through the proposed code assignment scheme, the voice service can be provided without the voice packet dropping probability in the CDMA/PRMA protocols. The code reservation is allowed to the voice and the videophone services. The low-rate data service uses the available codes during the silent periods of voice calls and the remaining codes in the codes assigned to the voice service to utilize codes efficiently. The high-rate data service uses the assigned codes to the high-rate data service and the remaining codes in the codes assigned to the videophone service. Using the Markov-chain subsystem model for each service including the handoff calls in uplink cellular systems, the steady-state performances are simulated and analyzed. After a round of tests for the examples, through the proposed code assignment scheme and the access permission probability, the Packet CDMA Reservation ALOHA protocol can guarantee the priority and the constant QoS for the handoff calls even at large number of contending users. Also, the data services are integrated efficiently on the multi-rate transmission.
