As electronic commerce is becoming more popular on the Internet, smart cards have been used for safe transfers and transactions on I-commerce popularly. Especially, Java Card considered as a COS for the next generation must take advantage of the good points of Java Language by using this language and making programs asked for by various demands. In this paper, we proposed efficient management system of mileage on the Internet using Java Card. The system has security for data and the simplicity of application development by Java Card cryptography. The system is an independent program saved un Java Card and can calculate and save mileage, although the characteristic of the mileage is different from others through the calculating Process of the Card. Also, the system is developed to encourage the efficiency of a system after comparing and contrasting between established systems and the newly designed one in simulation.

Interest rate options embedded in life insurance products provide policyholders with minimum guaranteed rates credited to the corresponding surrender values. This paper discusses current low-interest environment and several types of interest rate options embedded in life insurance products. In addition, this paper shows profit structures of the life insurance products and calculates values of the interest rate options under stochastic interest model and the corresponding VaR (value at risk). Finally, some implications are discussed.

고객관리가 대두되면서 고객유지 및 관리를 위한 마케팅 기법 중에서 중요한 것이 마일리지 적립마케팅이며, 대표적인 방식으로 자바 카드(Java card)와 같은 스마트 카드 방식 및 스티커 또는 쿠폰, 도장을 이용한 방식을 들 수 있다. 그러나 현재 많은 업계에서 도입한 마일리지 관리가 오히려 다수의 마일리지 카드 소지로 인해 고객에게 불편함을 주고 있다. 몇몇 기업에서는 같은 계열사의 마일리지를 통합 관리하는 방식을 선보였으나, 불편함을 줄이기엔 역부족이었다. 본 논문에서는 현재 국내 및 전 세계에서 스마트폰 이용이 확산되고 있는 시점에서 스마트 폰의 한 종류인 애플사의 아이폰 어플리케이션, 즉 앱(App)을 활용하여 개인의 마일리지를 보다 효율적으로 관리할 수 있는 마일리지 통합 관리 시스템을 제안한다.

The purpose of this paper is to design a platform that is easier for users to provide membership services to consumers in systems used for non-face-to-face orders such as interphones and kiosks than conventional systems. In the past, memberships used cards, smartphones, and personal information to create barcodes, but consumers have difficulty managing memberships that exist in each company, and as unmanned ordering stores through kiosks and interphones increase, more and more consumers do not accumulate membership services. In order to increase the usability of membership services, an integrated platform design for the utilization of membership services is proposed. The purpose is to integrate and provide each membership service history with one view, and to provide consumers with a platform to integrate and check multiple services into one.

시대가 발전함에 따라 무선통신 기술인 사물인터넷이 점차 성장하고 있으며 모바일 중심으로 IT환경이 재편됨에 따라 전자상거래의 결제방식 또한 변화하고 있다. IT시대에 맞춰 개인의 실시간 위치정보를 기반으로 홍보할 수 있는 지능적 마케팅 수단으로 하이브리드 비콘을 활용하여 고객이 매장근처를 지나치거나 방문할 때, 프로모션 및 쿠폰 정보를 전송하여 실시간 마케팅이 가능하게 한다. 하이브리드 비콘은 고주파의 특성상 매장 안팎의 고객 위치를 정교하게 구분 및 제공할 수 있으며, 블루투스의 연결이 끊기더라도 일정시간 동안 마케팅 서비스를 제공하는 강점이 있다. 본 논문에서는 하이브리드 비콘의 고주파와 저전력에 대한 강점을 활용하여 오프라인 매장에서의 고객에게 프로모션 정보나 모바일 적립 서비스를 제공함으로서 오프라인 시장의 마케팅 및 O2O시장 성장을 목표로 한다.

Since American Airlines's mileage program emerged in market, loyalty programs have gained popularity. Many companies have generated many kinds of reward cards in order to induce precious consumers. As a result, reward cards are very important in consumer goods market and become diversified. In spite of its importance, little is known about how these cards influence consumer's perception. The prior research has not focused on reward card types and psychological variables. Accordingly this research intends to investigate psychological variables such as transaction coupling and sunk cost perception. According to the theory of regulatory focus, promotion focus consumers would point to gain-nongain frame work, but prevention focus consumers would point to loss-nonloss frame work. The paper proved the effect of reward card types and regulatory focus on transaction coupling and sunk cost perception. Based on the results from 2(type of card : visible vs invisible) ${\times}$ 2(regulatory focus: promotion vs prevention) between-subjects factorial design experiments, we found that consumer's transaction coupling and sunk cost perception of visible reward card are better recognized than invisible reward card. In addition, the results show that there is a significant interaction effect between the type of reward card and regulatory focus. Specifically promotion focused consumers tend to reveal better perception than prevention focused consumers in use of invisible cards. However, prevention focused consumers tend to show better perception than promotion focused consumers in use of visible cards. These findings will contribute to significant academic development and practically useful help to marketing managers.

The purpose of this study is to analyze current condition and features of female development funds of Busan primary local self-government, and to make useful implications out of this so that the local female development funds can contribute to its ultimate purpose, which is to achieve female development. The analyses show that 1) local self-governmental districts with good finance try to reserve funds by reducing programs; 2) local laws, which serve as the legal basis of female development fund utilization, do not reflect the value of gender equality; 3) the programs run by the female development funds lack contents; 4) beneficiaries of the fund programs aremixed; and 5) female policies and family policies are not separated, exhibiting the limitations of feministic perspectives. I propose that 1) the fund should be raised through the governance of local female groups and self-governments; 2) basic local laws should be revised: 3) gender perspective contents and birth support policy should be implemented.

Both arterial dissection and atherosclerosis are major causes of cerebral infarction and appear to be occlusion or stenosis in magnetic resonance angiography(MRA) and computed tomographic angiography(CTA). But there are differences in treatment because they have different mechanisms. Recently, as high resolution magnetic resonance image(HR-MRI) develops, the image of blood vessel wall can be confirmed non-invasively. Though HR-MRI has become a very useful method for patients with suspected arterial dissection, differential diagnosis of the two diseases has not yet been fully established due to differences in the findings according to stages of arterial dissection and atherosclerosis. We investigated the differences between vertebral artery dissection and atherosclerosis through HR-MRI in two patients and confirmed the diagnosis by CTA follow-up. In addition to the previously established diagnostic criteria, we determined that the long and severe stenosis and recanalization suggest arterial dissection. Characteristics of arterial dissection confirmed by HR-MR and additional studies will be helpful for the treatment.

Recently, environmental sustainability of the transitional explosives and propellants is an issue of growing importance in energetic materials. For examples, ammonium perchlorate(AP) as an solid propellants oxidizer could create a poisonous gas and atmospheric pollutions, such as HCl. Among the several oxidizers, hydrazinium nitroformate(HNF) is an effective candidate substance for eco-friendly oxidizer, which has high density, pressure index, and less smog generating property during combustion for the Divert and Attitude Control System(DACS). This study was confirmed a synthesis through various conditions, was performed for the essential data of solubility the crystallization process. Also, crystallization process such as cooling, drowning-out and sonication were performed.
