최병규,이동복,김병곤,허신,Choi, Byoung-Kyu,Lee, Dong-Bok,Kim, Byung-Kon,Heu, Shin 한국정보처리학회 2012 정보처리학회논문지 A Vol.19 No.1

일반적으로 스마트카드라고 불리는 IC(Integrated Circuit)카드는 작은 크기의 마이크로칩(MPU)과 메모리, EEPROM, 카드 운영체제(COS) 및 보안 알고리즘을 내장하고 있다. 이러한 IC카드는 금융(카드,은행,증권 등), 교통, 통신, 의료, 전자여권, 멥버쉽 회원관리 등 거의 모든 산업분야에서 이용되고 있다. 최근 방송통신융합 및 TV의 스마트기기화 추세에 따라 TV전자상거래(T-커머스)가 방송산업의 신성장 동력이 되면서 T-커머스 지불결제 방법으로 IC카드를 이용하는 등 응용분야가 증가하고 있다. 예를 들어, T-커머스에서 IC신용카드(또는 IC현금카드)를 이용하여 결제를 하거나, IC현금카드를 이용하여 ATM과 같은 방식으로 TV뱅킹 서비스를 제공한다. 하지만 아직까지 대부분의 T-커머스 신용카드 결제 서비스는 리모콘을 이용한 카드정보 입력 방식을 이용하고 있기 때문에 고객 편의성이 크게 떨어지고, 카드정보 저장 및 노출 등 보안성에 있어서 취약성을 가지고 있다. 이러한 문제점을 해결하고자, 본 논문에서는 IC신용카드 결제 표준기술인 EMV기술을 이용한 TV전자 지불 결제시스템 구현을 위한 결제처리 모듈을 개발하였다. IC(Integrated circuits)card, generally be named smard card, embedded MPU(Micro Processor Unit) of small-size, memory, EEPROM, Card Operating System(COS) and security algorithm. The IC card is used in almost all industry such as a finance(credit, bank, stock etc.), a traffic, a communication, a medical, a electronic passport, a membership management and etc. Recently, a application field of IC card is on the increase by method for payments of T-commerce, as T-commerce is becoming a new growth engine of the broadcating industry by trend of broadcasting and telecommunication convergence, smart mechanization of TV. For example, we can pay in IC credit card(or IC cash card) on T-Commerce. or we can be provided TV banking service in IC cash card such as ATM. However, so far, T-commerce payment services have weakness in security such as storage and disclosure of card information as well as dropping sharply about custom ease because of taking advantage of card information input method using remote control. To solve this problem, This paper developed processing payment module for implementing TV electronic payment system using IC credit card payment standard, EMV.

We fabricates the $TiO_2$ thin film from anatase phase $TiO_2$ powder having good photocatalytic property using aerosol deposition method at room temperature. Aerosol deposition method, which sprays an aerosol powder with ultrasonic velocity and deposits a thin film on substrate at low temperature, has the advantages of low thermal stress and low cost. To fabricate the $TiO_2$ thin film, the aerosol bath pressure and chamber pressure were 500 torr and 0.4 torr, respectively. The difference of aerosol bath pressure and chamber pressure accelerated the $TiO_2$ nano powder to ultrasonic velocity through the nozzle of $0.4 mm{\times}10 mm$ and $TiO_2$ thin film was finally formed. SS mesh with diameter of 50 mm was used as a substrate to apply the $TiO_2$ thin film to water quality purification. The raw powder was dehydrated for the good dispersion of $TiO_2$ powder. To suppress the formation of second particle, the powder was dispersed for 90 min in alcohol bath by ultrasonic treatment and desiccated. The grain size of $1 {\mu}m$ was observed in $TiO_2$ thin film deposited on SUS mesh by scanning electron microscopy (SEM). The anatase phase of $TiO_2$ thin film was also observed by X-ray diffraction (XRD) and the anatase phase of raw powder was nicely maintained after aerosol deposition. The results are applicable to water treatment filter having photocatalytic reaction. 본 논문은 광 활성도가 가장 좋은 아나타제(anatase)상의 광촉매 $TiO_2$분말을 상온에서 aerosol deposition 법을 사용하여 박막을 제조하였다. 이런 제조 방법은 aerosol 분말을 초음속으로 분사하여 기판에 증착시키는 방법으로, 저온에서 박막증착이 가능하여 thermal stress를 줄일 수 있고, 공정 단가를 낮출 수 있다는 장점이 있다. 박막 제조시 aerosol bath의 압력은 500 torr이고, chamber의 압력은 0.4 torr 였다. 이런 압력차는 $0.4 mm{\times}10 mm$의 크기의 노즐을 통해 $TiO_2$ 나노 분말을 초음속으로 가속하여 기판에 증착시켰다. 박막 제조를 위해 사용한 기판은 수질정화에 응용하기 위해 직경 50 mm인 원판 SUS mesh를 사용하였다. $TiO_2$ 분말의 고른 분포를 위해 $TiO_2$ 분말에 함유되어 있는 수분을 제거하고 이차 입자의 생성을 억제하기 위해서 알코올 bath 속에서 90분간 초음파 세척을 한 후 건조하였다. SUS mesh 위에 증착되어 있는 $TiO_2$ 박막의 입자크기를 알아보기 위해 주사 현미경(SEM)으로 분석하였으며, $1 {\mu}m$정도의 입자 크기를 관찰 할 수 있었다. X-ray diffraction (XRD) 분석 결과 aerosol deposition 후에도 분말의 anatase상은 그대로 유지되었으며, 이런 결과는 광촉매 작용을 이용한 수처리용 필터로 활용이 가능하다.

In insurance contract law it is very important that the insured has to get sufficient information from insurer. Nowadays the insurance contract is very complicated. Therefore it is not easy to understand the contract concretely. Disputes are arising from the fact whether the insurer has offered sufficient information to insured. Therefore the insurance contract law should burden the insurer to offer sufficient information to insured. Nowadays many countries are making effort to get better insurance contract law. Germany has reformed the insurance contract law thoroughly in 2007. Japan has new, separate insurance contract law since 2008. The current korean insurance contract law in korean commercial code was effected in 1963. It has many problems. § 638-3 korean commercial code regulates the duty of insurer to explain the insurance contract clauses. But it is not sufficient. In that regulation there is no content about the effect of non-explanation. And § 7 german insurance contract law(VVG) are the regulations that burden the insurer to offer sufficient information to insured by the process of making contract. When the insurer violates this regulation, the insured can cancel the contract in 14 days. It has more detailed contents as korean commercial code. For instance it is not regulated in korean commercial code expressly, then the insurer offer information and which informations should be delivered to insured. The german change in regard of offering informations to insured is key point of the reform of the year 2007. We should also regard this change in germany. The reform discussion about korean insurance contract law is being done in korean national assembly. The ministry of justice has also established a reform commission in the part of insurance contract law. By the reform discussion in korea we can also consider adopting more detailed regulations about agreed value. By the work the german example(§ 7 VVG) can give us good suggestions.

Nowadays every person has bank account. Bank trade plays very important role in everyday life of the people. Korean people want to habe their own houses. Therefore they borrow money on their house. This is so called mortage loans. Subprime mortage was a cause of the global financial crisis in the year of 2007, 2008. On the other hands, standard contract terms has important roles in modern, mass product society, especially in the field of bank business. But the interest of the clients can be neglected by the unfair standard contract terms about the bank trade. Therefore, it happens very often that people confront problems with the use of inadequate standard contract terms. This study concentrates on analysing the contract terms about the bank business. The contents of standard contract terms about bank business should be valid in regard of korean unfair contract terms act and jurisdiction. There were some discussions about the problem, who should bear the fee for getting mortage in korea. The old standard contract terms about bank business allows the selection of the parties in this point. But the korean fair trade commission has revised the standard contract terms about bank business. It has also enforced the new clauses to all banks. The bank association sued the fair trade commission. The seoul high court accepted the claim of the bank association. But the supreme court has broken off the decision and refer the case back to seoul high court. The seoul high court is now reexamining the case. The author has in this article analyzed court cases about this problem. The old standard contract terms about bank business is valid in regard of § 6 korean unfair contract terms act. The revised standard contract terms about bank business, in short, has problems. The older clauses are adequate in regard of the interest division of the parties. Therefore the fair trade commission should not enforce the new clauses. But some standard contract terms of bank business is vague. Therefore, it should be defined more clearly.

Nowadays trade volumes are also symbol of competitiveness of one country. In the mean time, korea became the 7. large export country in the world(2010). The korean government has offered special effort and support to export companies. One of them is the Export credit insurance. Not only export, but also import play very important role in modern economic society. Import credit insurance in general has some special character. The import insurance and the export insurance is nonprofitable policy insurance. In korea export credit insurance was held by Korea Export Insurance Corporation(KEIC). But the KEIC was changed to Korea Trade Insurance Corporation(K-Sure) in the year of 2010. At that time the Export Credit Insurance Act was changed to Trade Credit Insurance Act. Because of this change, K-Sure handles not only export credit insurance, but also import credit insurance. K-Sure has been committed to promoting sound overseas transactions since its establishment in July 1992. K-Sure compensates the losses arising from import transactions and overseas investments that cannot be handled by the general insurance systems, and provides useful information to its customers. Always looking beyond its success, K-Sure is making effort to meet the various needs of its customers, while furthering international cooperation and striving to become one of the leading import and export credit insurance institutions in the world. Import credit insurance compensates the credit risk and emergency risk. The objects of it is the import of material resources that are very import for the national economy. Pure consumption goods are not the objects of this insurance. It is introduced in korea since July 2010. This study handles the characteristic of the import credit insurance. By the analyse, it concentrates on showing the differences between the general principles of civil based insurance and import credit insurance. The author has mentioned as example the duty of disclosure and indemnities in the field of general contract terms of import credit insurance. Cases of import credit insurance have meanwhile shown some problems in regard of general principles of insurance. But it has the ground on special character of import credit insurance. Because the import credit insurance is a sort of company based insurance, not consumer based insurance. Therefore it can be partly justified. The author tried to point out the differences between import credit insurance and general civil based insurance. And he has suggested that some clauses of the import credit insurance should be changed.
