Purpose: The use of e-Samsat services in East Java has not been significant in the amount of use of its services for tax payments as a whole. The purpose of this study is to analyze what factors East Java e-Samsat services practice and the existence of recommendations as a basis for government decisions to improve the quality of East Java e-Samsat services. Research design, data and methodology: Our model hypothesizes that three key factors determine the intention to use e-samsat platform such as: trust, awareness, ease to use. Data collection methods by distributing questionnaires and interviews. Results: The results of the study provide two findings, firstly, Trust, Ease of Use, Awareness directly or indirectly affects the Intention to Use the East Java e-Samsat service for motor vehicle taxpayers. Thus it is essential to pay attention to these three variables in terms of clarity, reliability, and timeliness as a recommendation to improve the quality of East Java e-Samsat services.. Conclusions: The results of this study can be applied and developed in other countries besides Indonesia with the same cultural patterns. Several variables have been measured in previous studies in several Asian continent countries.

비트코인에 기반한 블록체인 기술은 익명성이 있는 스마트 계약, 저렴한 송금, 온라인 거래 등을 가능하게 하는 하부구조를 제시하고 있다. 하지만, 비트코인을 구현하는 블록체인 기술은 처리량과 지연시간 간의 트레이드오프 관계에 있는 확장가능성 제한을 갖고 있다. 이러한 문제를 해결하기 위한 비잔틴 고장 감내 기반 블록체인 기술이 제안되었다. 이 기법은 리더를 선출하고 리더에 의해 기존 블록 내에 작업증명을 포함하지 않는 많은 마이크로 블록을 구성하여 지연시간 증가 없이 처리량을 향상시켰다. 하지만 이 기법은 리더를 선출하는 부분에서 기존 기법보다 보안성이 떨어질 수 있다. 본 논문에서는 마이크로 블록기술과 병행수행 기법을 통해 블록체인 기술의 확장가능성을 위한 기법을 제안한다. 하나의 마이크로 블록 내에는 여러 개의 거래에 대한 정보가 있다.

The ability of smartphones to facilitate various services like mobile banking, e-commerce and mobile payments has made them part of consumers' lives. Conjoint analysis (CA) is a marketing research approach used to assess how consumers' preferences for products or services develop. The potential applications of CA are numerous in consumer electronics, banking and insurance services, job selection and workplace loyalty, consumer packaged goods, and travel and tourism. Choice-Based Conjoint (CBC) analysis is the most commonly used CA approach in marketing research. The purpose of this study is to utilise CBC analysis to investigate the relative importance of smartphone attributes that influence consumer smartphone preference. An experiment was designed using Sawtooth CBC Software. 326 students attempted the online survey. Utility values were derived by Hierarchical Bayes (HB) estimation and used to explain consumers' smartphone preferences. All the six attributes used for the study were found to significantly influence smartphone preference. Smartphone brand was the most important, followed by the price, camera, RAM, battery life, and storage. This study is one of the first to use Sawtooth CBC analysis to assess consumer smartphone preference based on the six attributes. We provide implications for the development of new smartphones based on attributes.

The use of mobile payment services has recently increased in South Korea. Mobile payments allow consumers to purchase items digitally, using a mobile card in an app affiliated with a payment service. This study explores the predictors of intention to adopt mobile payment services. The study employed an A(affective)-B(behavioral)-C(cognitive) model with two antecedent variables: cognitive (perceived usefulness, perceived risk, perceived ease of use, and perceived herding behavior) and affective (satisfaction with the status quo, innovation resistance) responses. An online survey of 405 non-users of mobile payment services aged 20 to 49 years was conducted. The study used SPSS 23.0 for descriptive analysis and Amos 23.0 for confirmatory factor analysis and structural equation modelling. The results are as follows. First, perceived usefulness, perceived risk, and perceived herding behavior significantly influenced innovation resistance. Second, perceived herding behavior significantly influenced subjective norms. Third, innovation resistance and subjective norms significantly influenced the intention to adopt mobile payment services. The findings suggest that the A-B-C model can be useful in understanding consumers' adoption and resistance behaviors and that cognitive and affective responses are important antecedent variables affecting the decision to adopt mobile payment services.

현재 온라인, 모바일 게임에는 '가챠' 시스템이란 뽑기 시스템이 없어서는 안 될 수익창출 방법으로 자리 잡고 있다. 이 시스템은 '확률성 무작위 뽑기'라고도 불리며 현금을 이용한 결제로 진행되며 얼마를 사용해야 원하는 아이템을 얻을 수 있는지 확실하지 않다. 그래서 이용자들의 반발로 게임사들은 일정 금액 이상으로 사용하면 원하는 아이템을 얻는 '천장' 시스템을 도입했고, 이를 활용해 여러 수익 창출법을 추가했다. 이 시스템이 지속 과금 유도에 미치는 영향에 대해 알아본다.

모바일은 단순한 콘텐츠 소비도구를 넘어 독점적 플랫폼 역할로 확장되어 가고 있다. 모바일 콘텐츠란 모바일 기기를 이용한 업체들의 서비스를 말한다. 장점은 이용자의 행동을 실시간으로 분석할 수 있어서 취향에 맞춰 만족도를 높일 수 있다. 반면 단점은 편리한 온라인 결제환경으로 미성년자들이 쉽게 유료결제를 할 수 있다. 콘텐츠 무단도용플랫폼을 사용하지 않고 자극적인 미디어에 무방비하게 노출되지 않도록 조심해야한다. 또한 모바일 콘텐츠 플랫폼의 순기능을 키우고 역기능을 줄이는 방안을 모색하여야 할 것이다.

This study aims to compare the experience of selected countries in operating separate payment system for new healthcare technology and to find implications for price setting in Korea. We analyzed the related reports, papers, laws, regulations, and related agencies' online materials from five selected countries including the United States, Japan, Taiwan, Germany, and France. Each country has its own additional payment system for new technologies: transitional pass-through payment and new technology ambulatory payment classification for outpatient care and new technology add-on payment for inpatient care (USA), an extra payment for materials with new functions or new treatment (C1, C2; Japan), an additional payment system for new special treatment materials (Taiwan), a short-term extra funding for new diagnosis and treatment (NUB; Germany), and list of additional payments for new medical devices (France). The technology should be proven safe and effective in order to get approval for an additional payment. The price is determined by considering the actual cost of providing the technology and the cost of existing similar technologies listed in the benefits package. The revision cycle of the additional payment is 1 to 4 years. The cost or usage is monitored during that period and then integrated into the existing fee schedule or removed from the list. We conclude that it is important to set the explicit criteria to select services eligible for additional payment, to collect and analyze data to assess eligibility and to set the payment, to monitor the usage or cost, and to make follow-up measures in price setting for new health technologies in Korea.

The demand of renewable energy is expected to grow in the long run in spite of current stable lower oil prices. Energy consumption for heating in horticulture greenhouse is large and affects the profits of the farms. This study analyzed the availability of biomass in rural area and proposed the strategies for utilizing the biomass for greenhouse heating. Data reveal the annual average fuel consumption in greenhouses is about 78 TOE/ha. Considering biomass resource in rural areas, agricultural residues are not sufficient to meet the biomass demand from greenhouses. Therefore it is recommended to secure further biomass including wild herbaceous biomass and woody biomass from forest. Based on the conditions of biomass gasification equipment investment and fuel prices, maximum allowable price of biomass turned out about 100,000 KRW/t to be competitive to kerosine. Biomass supply chain should be established for facilitating biomass trading between biomass consumers and biomass producers such as farmers who provide crop residues. An online trading system is an example of the system where consumers who utilize biomass make payments to suppliers and get the information about the biomass. Intermediate collection storages are required to store biomass from distributed sources. Operation of biomass heating systems in demonstration greenhouses is necessary to get information to refine and further develop commercial biomass heating systems. Relatively large greenhouses are desirable to have biomass heating systems for economic viability. The location of the greenhouse farms should be selected within the area where enough biomass resources are available for feeding the biomass facility.
