Korea's conventional iPhone users had to pay for their applications in dollars. However, Apple will have to consider implementing a payment system in Korean won. Apple has strongly insisted on using the payment system in dollars, but despite its relatively small sales proportion, it will turn to the Korean market that ranks 3rd in the world for its number of downloads. In other words, the Korean market has tremendous potential for growth. Thus, this study aimed to analyze the changes that will be experienced by Apple in the Korean market due to the implementation of the iPhone-based won payment system, price fluctuations due to the introduction of iTunes, as well as positive aspects and implications of Apple's market expansion in Korea when users make payments in Korean won.

The purpose of this paper is to analyze the difference of the value in main production areas affected through the hedonic price model and the conjoint analysis. In addition, the partial value of each attribute level, and the consumers' willingness to pay(WTP) for change in each attribute level are analyzed. For this, we compared the value of apple determined in Garak market with the value that consumers' WTP. The result showed that there is a gap between the market value and the consumers' preferences on apple. It means that it is necessary for the local branding to be more developed to receive higher sales. Furthermore, understanding the consumers' preferences on the apple attributes can enhance the consumer utility and the competitivity. As a result, this study provides an apple marketing direction for main production areas that has been changing due to climate change.

This study examines a data-driven approach for software test automation at an online shopping site. Online shopping sites typically change prices dynamically, offer various discounts or coupons, and provide diverse delivery and payment options such as electronic fund transfer, credit cards, mobile payments (KakaoPay, NaverPay, SyrupPay, ApplePay, SamsungPay, etc.) and so on. As a result, they have to test numerous combinations of possible customer choices continuously and repetitively. The total number of test cases is almost 584 billion. This requires somehow automation of tests in settling payments. However, the record playback approach has difficulties in maintaining automation scripts due to frequent changes and complicated component identification. In contrast, the data-driven approach minimizes changes in scripts and component identification. This study shows that the data-driven approach to test automation is more effective than the traditional record playback method. In 2014 before the test automation, the monthly average defects were 5.6 during the test and 12.5 during operation. In 2015 after the test automation, the monthly average defects were 9.4 during the test and 2.8 during operation. The comparison of live defects and detected errors during the test shows statistically significant differences before and after introducing the test automation using the data-driven approach.

The aim of this study is to scrutinize acceptance intentions of Korean users and influences of information security related factors on mobile payment services based on biometric authentication methods, like finger print authentication or face recognition authentication, by focusing on ApplePay. Unlike previous studies on user acceptance of mobile payment which lack considerations on information security related factors, this study employs the UTAUT with detailed information security factors to create a research model and PLS(Partial Least Squares) method to analyze the model. Based on the analysis, gaining trust on service through company's efforts on information protection, personal characteristics and trust on applied security technologies are important factors to Korean users along with social awareness and service infrastructures. The result of this study would be helpful to companies or organizations, which provide biometric-based mobile payment services, to understand needs of Korean consumers. Based on this study, further analysis is expected to find impacts of user experiences on same company's or competitors' products to acceptance intentions.

This study first introduces platform services and their business models. On the basis of the concepts of business ecosystem, we present a framework for distinguishing types of the platform service business models. Two key characteristics of business ecosystems-ecosystem configuration and value production process-are employed as fundamental dimensions for constructing typology. In particular, we also present the notion of value ecosystem, where not a single platform provider but a federation of platforms constitutes a virtual platform and completes a service system. The value ecosystem represents two distinct types of platform service business models : meta-platform ecosystem and platform coalition ecosystem. They show different governance structure in the platform federation and service flows across the ecosystem. We present detailed analyses of these two value ecosystems focusing on relevant cases of e-payment FinTech : Apple Pay as an example of meta-platform and Kakao Pay for platform coalition. Our conceptual typology contributes to platforms' proper strategy formulation and presents policy implications to, for example, platform neutrality.

Recently, biometric technology has begun to be used as a fusion of IT technology and financial system. Using this biometric technology, FIDO(Fast Identity Online) technology, Samsung and Apple started Samsung Pay and Apple Pay service. FIDO authentication technology replaces existing authentication methods such as passwords. Among the biometric technologies, fingerprint recognition technology is attracting attention because it can minimize the device and user rejection at a relatively low price. However, fingerprint information has a limited number of users and it can not be reused if fingerprint information is leaked by an external attacker. Therefore, in this paper, we propose a method to authenticate a user using EEG signal which is one of biometrics technologies. W propose a method to use EEG signal measurement value in FIDO system by using convenience channel by using short channel EEG device. And propose a method to utilize EEG signal when the user recognizes a specific entity by measuring the EEG signal before and after recognizing a specific entity.

The physicochemical characteristics and consumer perceptions of two Fuji cultivars (Fuji and Royal Fuji) with six different size groups (3D: 30~39, 4D: 40~49, 5D: 50~59, 6D: 60~69, 7D: 70~79, and 8D: 80~89 apples/15 kg) were investigated to identify the ideal size and the drivers of consumer acceptability of apples. For the physicochemical characteristics, the weight, volume, specific volume, L, a, and b colors, hardness, pH, acidity, and brix of apples were measured. A total of 100 consumers were asked to mark the intensity of the characteristics (size, redness, glossiness, surface roughness, apple odor, apple flavor, sweetness, sourness, hardness, crunchiness, and toughness) to determine the ideal characteristics of apples before they were asked to taste the apple products. The consumers evaluated the apple samples in terms of their appearance, odor, flavor, texture, and overall acceptability; the consumers' intent to purchase such apples and willingness to pay for them; and the intensity of the aforementioned characteristics. Compared to the ideal characteristics of apples, the actual apple samples were rated low in their apple odor, apple flavor, acidity, sweetness, hardness, and crispness. The ideal size of the apples was between 4D and 5D. Their overall acceptability was highly affected by their flavor, followed by their texture, odor, and appearance. The acceptability of the appearance was highly correlated with the glossiness (r = 0.80), volume, weight, redness (r = 0.73), and size (r = 0.72). The consumer acceptability of the apples increased with the decreased pH and the increased Brix, hardness, and color b values of the peeled apples. The apple flavor, sweetness, hardness, crispiness, juiciness, and toughness during mastication were noted as sensory drivers of consumer acceptability.
