Purpose: Avulsion injuries of digits have been presented for a long time as complex management problems. Despite of microsurgical advances, it is difficult to achieve good functional results and their management remains somewhat controversial. However, in a finger there are three transverse digital palmar arches. The middle and distal transverse digital palmar arches are consistently large(almost 1 mm) and may be used for arterial vessel repairs either proximally or distally, depending on the length and direction needed. 39-year-old man presented with avulsion amputation of the ulnar three digits, was operated using only arterial anastomosis with rerouting the transverse digital palmar arches. Methods: Replantation was performed using the artery-only technique. Because the digital arteries had been damaged, we did that the transverse digital palmar arches were transposed in an inverted Y to I configuration and were lengthened with rerouting them for the purpose of direct anastomosis of the digital artery. Venous drainage was provided by an external bleeding method with partial nail excision and external heparin irrigation. Results: The authors conclude that complete avulsion amputations with only soft tissue at the distal to insertion of the flexor digitorum superficialis tendon were salvageable with acceptable functional results. All three fingers survived. Conclusion: With technical advancements, the transverse digital palmar arches play an important role for finger amputation. Three digital palmar arches give us additional treatment option for the finger amputation. In this case, replantation with only-arterial anastomosis was successful and we obtained good aesthetic and functional outcome.

Purpose: Increasing advancements in the technology industry are forcing people to become more accustomed to digital financial transaction activities. The need for fast and secure payment mechanisms has birthing new idea to digital financial transaction services. Along with increasing access to technology in digital payments, new service is developed in the form of digital wallets as the successor for electronic money. Research design, data and methodology: This research aims to find out whether using QR code as digital payment tool can build customer loyalty in consumers, especially to measure the factors of satisfaction, trust and commitment of customers to do payments with QR Codes. The QR code in this study is refer to the Quick Response Code Indonesian Standard (QRIS) which was officially implemented by Bank Indonesia starting on January 1, 2020 as a means of payment for digital transactions nationally. The research method uses a quantitative approach by way of surveying questionnaires using Likert scale of 100 samples. Results: The hypothesis analysis proved that the variables of satisfaction, trust and commitment together have positive and significant influences on customer loyalty. Conclusion: This research found that there are high interest in Millennials to do transaction using QRIS because it is deemed to be more easy, quick and safe. If a customer achieves a level of loyalty in the usage of digital transaction using QRIS then cashless society lifestyle can be considered successful and can be used in the future.

This study analyzed the illustrations presented in the elementary science paper textbooks and digital textbooks under the 2015 revised curriculum in terms of gender role stereotypes. The frequency of pupils and adults on illustrations was counted by gender, and the types of activities and behavior of characters were analyzed. For pupils, paper textbooks showed a higher frequency of girls than boys, and digital textbooks showed similar gender rates. In the aspect of the activity, paper textbooks showed similar gender rates in non-learning activities, but more girls in learning activities. In digital textbooks, the learning activity was balanced by gender, but the non-learning activities presented boys more frequently. For both paper and digital textbooks, most pupils were described to be active regardless of gender. For adults, paper textbooks were balanced in the frequency by gender, but digital textbooks had a higher proportion of men. Paper textbooks showed similar gender rates in out-of-home activities, but more men in housework activities. In digital textbooks, housework activities were balanced by gender, but out-of-home activities presented men more frequently. For both paper and digital textbooks, men appeared in a broader range of occupations than women. Female scientists appeared more than male scientists in paper textbooks, and opposite tendency appeared in digital textbooks. As a result of analyzing the characteristics of adults, both paper and digital textbooks showed gender stereotypes in specific behavioral characteristics.

본 논문에서는 급증하는 사회적 문제인 자살에 대해 가상현실 체험을 통해 예방할 수 있는 콘텐츠 설계를 제안한다. 엔터테인먼트 형태의 콘텐츠로 뇌파 측정을 하여 자살증후군을 가진 대상자를 선별하고 이에 따른 자살동기 유형별 적합한 자살예방콘텐츠를 설계하는 것이다. 콘텐츠 설계는 자살예방을 위한 검증된 프로그램을 적용하고 사용자의 자연스러운 몰입을 유도하도록 VR 기기를 활용한다. 콘텐츠 사용을 통하여 수집된 데이터 분석으로 오프라인 전문가의 심층적인 치료 및 교육이 가능하도록 연계한다. 본 논문에서 설계된 콘텐츠를 이용하여 자살에 대한 경각심을 주거나 예방을 할 수 있을 것으로 기대한다.

A new analog-la-digital structure. called cyclic-parallel analog-to-digital(A/D) converter, has been developed for video applications. It consists of a M-bit parallel A/D converter, a digital-to-analog(D/A) converter, a differencing amplifier with gain of $2^M$ and two sample-and-hold circuits. In this structure, the input signal is circulated around the circuits K times, thereby converted into a MK-bit digital word. The proposed converter retains speed advantages of conventional series-parallel converters, with half reduced circuit components.

A demand on the spatial data management has been rapidly increased with the introduction and diffusion process of ITS, Telematics, and Wireless Sensor Network, and many different people use the digital map that offers various thematic spatial data. Spatial data for digital map can manage to tile-based and feature-based data. The existing tile-based digital map management systems have difficult problems of data construction, history management, and updating based on a spatial object. In order to solve these problems, this paper proposed the data model for the feature-based digital map management system that is designed for feature-based seamless map, history management, real-time updating of spatial data, and analyzed the validity and utility of the proposed model.
