현재 대형 마트에서 '미래형 매장(Future Store)' 을 구현하기 위하여 스마트 카트를 운영하고 있다. 스마트카트의 운영은 고객에게 물품의 정보, 해당 물품의 위치, 구매한 물품의 리스트 등 다양한 정보를 제공해주며 고객들에게 우수한 서비스를 제공한다. 하지만, 이런 스마트 카트는 큰 단점을 포함하고 있어, 많은 매장에 상용화 되기란 어려움이 예상된다. 이를 해결하기 위하여, 요즘 화제가 되고 있는 스마트폰을 이용하여 스마트 카트의 우수한 서비스를 제공하고자 한다.

RFID 미들웨어에서 저장소 역할을 하는 EPCIS는 이전까지 물품의 식별 정보만을 저장 및 관리하고 있었다. 하지만, 최근에는 많은 물류 분야의 응용에서 물품의 식별 정보뿐만 아니라 센서 및 위치 정보 등을 포함하는 다양한 물류 정보를 EPCIS에서 저장 및 관리하도록 요구하고 있다. 하지만, 현재 EPCIS에서는 RFID 태그의 식별 정보 이외의 정보에 대하여 처리를 하지 않고 있으며, 설령 처리한다하더라도 비효율적인 조인으로 인한 속도 저하가 일어날 수 있다. 즉, 각 정보 소자에 대한 복합 정보를 요구하는 응용에서는 개별적인 시스템에 질의를 한 후 결과를 조합해야 하는 부담이 있다. 본 논문에서는 물품의 식별 정보, 센서 및 위치 정보를 포함하는 지오센서 태그 데이터에 대한 효율적인 처리를 지원하기 위한 다양한 물류 환경의 정보와 질의 조건의 특징을 분석하며, 분석된 내용을 바탕으로 데이터 모델링을 제시한다.

It requires professional knowledge and much time to judge intellectual property rights infringement. The duties of customs administration are the balance between the propositon of trade facilitation through rapid clearance and the thesis of social security through exact examination. There is a view that the criminal procedure law control is necessary to the goods inspection of clearnce procedure if it is related to crimianl investigation. However, it seems that the customs law does not consider the goods inspection investigation as the investigation under judicial control, but only the mere administrative investigation. It can be said that the inspection of goods by customs law functioning as a clue of investigation is confined to the ordinary goods inspection, including the screening test. Searching for specific articles by specific informaition should be under the control of criminal procedure law because it constitutes the commencement of criminal investigation in criminal cases. This interpretation could be an opportunity as a harmonious operation between the goods inspection of customs clearance and the search and seizure of criminal procedure.

RFID와 sensor network의 두 기반 기술은 독특한 물리적 특정을 가지며 상호 보완적인 관계를 가지고 있다. 이러한 관계는 창고 안 물품의 상태파악과 입출 재고를 관리하는 형태로 응용된다. 창고 내 물품 보관 단위인 파렛트(Pallet) 에 RFID 태그를 부착하여 입/출고시의 물품을 식별한다. 그리고 Zigbee 무선 통신기능을 가진 센서 모듈에 의해 물품의 환경 상태 정보를 파악한다. 이후 현장 관리자나 소비자들은 이동형 단말장치를 통해 현장에서 다양한 USN 상의 정보들과 상호작용 한다. 이 과정에서 이동형 단말장치를 통한 RFID tag 정보와 센서 노드의 접근이 공중파 상에 노출 된다. 이러한 센서 노드 접근을 보호하기 위해 추가적인 칩 설계 등의 비용 지불로 기밀 노출에 대처할 수 있다. 이에 대한 대안으로 인프라형태로 놓여진 RFID tag와 단말장치에 탑재될 RFID 리더를 활용해 더 적은 비용으로 보안 서비스를 받고자 한다. 그래서 유비쿼터스 환경에서 센서 노드에 대한 접근을 제어하기 위해 RFID tag를 지역키(local key) 처럼 사용한다. 또한 이 과정에 보안이 적용된 프로토콜을 설계 하는 것이 본 논문의 주된 목표이다.

This paper investigates the difference of writing requirements between the UCC2. and the UN convention on international sales of goods (CISG). To do it, the U.S writing requirement by statute of frauds was introduced by two sources of laws including common law and UCC${\S}$2-201. Although the U.S. statute of frauds requires some contract to be written with formalities, the way the requirement is satisfied is quite flexible in terms of its formalities. The UCC is more flexible than the common law in its formalities. The CISG does not require the sales contract to be written with any format, which is totally different from the U.S statue of frauds. Such differences between the U.S laws and CISG in writing requirement were investigated in the context of conflicts of laws.

The ultimate purpose of this study is to improve the irrational system related to flame retardant coating performance test of field flame retardant coating articles and to secure the reliability of flame retardant coating through rational flame retardant coating test. To achieve this, the analysis was conducted on the interior finishing materials used in the interior fields and the trends of recent field flame retardant coating, based on the results of flame retardant coating performance test of field flame retardant coating articles which the first-line fire stations have recently conducted. And I attempted to present the methods of field flame retardant coating performance test suitable to current realities and the ways of improvement for securing reliability by analyzing the problems with the methods and procedures of field flame retardant coating articles and the registration system of flame retardant coating business.

Similar patterned fire incidents such as, Inchon Live-Hof Pub Restaurant as, Sea-land Children Resort have proven that serious loss of lives were caused by hazardous gas generated from a combustion of interior finish and decorative materials. Therefore, comparing Korean fire regulation with other countries fire code, e.g. UK, USA, France about limitation of interior finish and decorative materials in premises as assemblies, differences & problems have been int estimated and analyzed on hew serious they may affect on fire spread and smoke development based on analyze facts. It is suggested that Korean fire code would be revised in order to reduce hazardous interior finish materials from special occupancy and adapted new test methods to verify proper fire performance in premises as assembles which require a fire certificate. Finally, detailed code alternatives will be suggested in order to set up effective fire regulation, which could promote preventing serious loss of lives in future.

We are investigated about the Hepatitis infection risk of the funeral director related to wearing PPE(Personal Protect Equipment) within Metropolitan, Chungcheong and Gyeongsang regions in Korea. We are classified that the vaccinated group was classified as low risk group and the non-vaccinated group was classified as high risk group. And we are analyzed the risk rate of infection based on whether or not to wear PPE(personal protective equipment) among high-risk groups. The result is as follows. The mask wearing rate of high-risk group about HAV(hepatitis A virus) is three times lower than that of low-risk group. The surgical glove wearing rate of high-risk group about HBV(hepatitis B virus) is twice lower than that of low-risk group. The surgical glove and mask not wearing rate among the high-risk group observe that potential infection risk was high 4.23 times and 3.5 times, respectively. We are concluded that increasing the risk of potential infection risks from the funeral director could result in increased risk of infection to national public health, including the bereaved family. We are suggested that the funeral director must be bound to vaccinate against hepatitis and make PPE mandatory. It is deemed necessary for the government to develop policies to promote personal health and national health care.

In present, physical distribution industry fields are offering more convenient services using RFID, but there is plenty of room for improvement. And then, utilizing advantages of RFID which quick and simple manages goods and GPS which gets information of position at the present, we implemented a physical distribution management system can manages the information for distribution process of goods easier. We can get much information that the number of loaded goods, the data of goods, the state of distribution, whether or not missing, etc. as attached a RFID reader to the truck. and when truck is moving, we can also obtain much information consumer want that the real time data of position, distribution routes, etc. for loaded goods as received a latitude and longitude from GPS. These information have recorded, managed, and linked Google map, we can grasp the distribution information of goods on World Wide Web service. Because this service is focus on the image not the text can give the information required by the consumer on visual, it is different from the existing service. At this point of time that the RFID and GPS have used in overall industry, If these services have researched and developed with transportation, tour, etc. industry as well as physical distribution, it is possible to utilize more widely.
