A systematic approach for interpreting Korean addresses based on postal code is presented in this paper. The implementation is focused on producing the final delivery point code from various types of address recognized. There are two stages in the address interpretation : 1) agreement verification between the recognized postal code and upper part of the address and 2) analysis of lower part of the address. In the agreement verification procedure, the recognized postal code is used as the key to the address dictionary and each of the retrieved addresses is compared with the words in the recognized address. As the result, the boundary between the upper part and the lower part is located. The confusion matrix, which is introduced to correct possible mis-recognized characters, is applied to improve the performance of the process. In the procedure for interpreting the lower part address, a delivery code is assigned using the house number and/or the building name. Several rules for the interpretation have been developed based on the real addresses collected. Experiments have been performed to evaluate the proposed approach using addresses collected from Kwangju and Pusan areas.

In this paper, we propose a coding packet group-based ARQ scheme (rNC) for file delivery in wireless networks. rNC assumes multiple network coding points between the source and the destination. Each network coding point gathers and codes a group of packets according to the queue polling system. A queue polling system makes a few or several packets available for coding in a queue while polling the other queues in the system. Thus, we assuem a queue polling system at each network coding point. We call this group of packets as coded packet group. Each coding point acknowledges the reception of every code packet group to its previous coding point for reliable delivery. Thus, the intermediate coding points including the source can release its buffer before the packet is delivered to the destination. To guarantee the ultimate file delivery to the destination, the destination sends acknowledgement to the sender. We evaluate our proposed scheme using ns-2 and compare the performance with CodeCast. The results show that rNC works better than CodeCast in terms of packet delivery ratio and control overhead in unreliable wireless networks.

"Domestic delivery service" is defined the service to deliver goods or packages from point of senders to point of receiver. With the characteristics of door to door, it is must a service provider should know the exact location of destination assuring best utilization of moving path. Generally, location information consist of postal code and address only, which result in difficulties to identify the precise location of destination. It is relatively less correlated between the information that address refers and practical location in Korea address system. For example, the next door to house number 100 is not always house number 101. Therefore, a delivery man additionally uses a paper map or a GPS navigation which carry extra job to input every code of location to the device in order to know precise location. It is also very inconvenient that every delivery man identify the location that address information refers and make a personal decision of the optimum moving path dropping each destination without calculating provisioning process of whole delivery path. As explained above, it is inefficient to find information delivery service required and to generate the optimum path. In results, these difficulties bring in delay of service and increase of cost. In this point, the contents of the thesis suggest a GPS navigation system easy to obtain accuracy of delivery information which enables to automate optimum moving path based on RFID which contains location information.

In recent semiconductor and FPD (Flat Panel Display) manufacturing processes, high clean-class delivery operation is required more and more for short working time and better product quality. Traditionally SLIM (Single-sided Linear Induction Motor) is widely used in the liner drive applications because of its simplicity in the rail structure. A magnetically levitated (Maglev) unmanned vehicle with SLIM traction, which is powered by a CPS (Contactless Power Supply) can be a high precision delivery solution for this industry. In this paper unmanned FPD-carrying vehicle, which can levitate without contacting the rail structure, is suggested for high clean-class FPD delivery applications. It can be more acceptable for the complex facilities composed with many processes which require longer rails, because of simple rail structure. The test setup consists of a test vehicle and a rounded rail, in which the vehicle can load and unload products at arbitrary position commanded through wireless communications of host computer. The experimental results show that the suggested vehicle and rail have reasonable traction servo and robust electromagnetic suspensions without any contact. The resolution of point servo errors in the SLIM traction system is accomplished under 1mm. The maximum gap error is ${\pm}0.25mm$ with nominal air gap length of 4.0mm in the electromagnetic suspensions. This type of automated delivery vehicle is expected to have significant role in the clean delivery like FPD glass delivery.

This study focuses on the Mise-en-abyme theories of Lucien $D{\ddot{a}}llenbach$, and presents research methodology to analyze the modern cinema costume in a new view. Inherent aesthetic values of the costume code shown in the film are as follows. First, esthetics value shown is the analogic code through the maximization of factual realism by directing target. Mise-en-abyme placed in this film plays the role of costume codes, and highlights the subject by presenting specifically targeted realistic icons to maximize the realism of the movie. Second, Mise-en-abyme is deployed to the explicit text through costumes code is placed as Displaced code arrangements. In other words, each of the characters is a signifier. Symbolizing a historical era is the device that represents a self-reflective signifier. Third, paradoxically reflected by the overlapped expansion of virtual reality and the self-referential characteristics and are subject to reflect the thinking of the author. Costumes code placed in Mise-en-abyme is expressed in costumes positioned to maximize the realism in the film as described above, and implies narratives and self-reflective mediating tools that symbolism can be seen that the paradoxical metaphor for the reality and the future. In addition, through the metaphor of visual narrative is allegorical representation Mise-en-abyme with ambiguity, and it is a concrete text that can be realized in a variety of creative storytelling methods and image delivery methods of modern fashion. This study confirmed that this costumes to take the point of view of emotional $Mise-en-sc{\grave{e}}ne$ in the process of completing the film's themes and cinematic devices by identifying the roles and aesthetic value of code costumes as the core subjects that make up the narrative of the film.

As the portion of information systems (IS) budget to the total government budget becomes greater, the cost estimation of IS development and maintenance projects is recognized as one of the most important problems to be resolved for scientific and efficient management of IS budget. Since IS budget makes much effect on the delivery time, quality and productivity of IS projects, the exact cost estimation is also necessary for the successful accomplishment of IS projects. The primary concern in the cost estimation of IS projects is software cost estimation, which requires the measurement of the size of softwares. There are two methods for sizing software : line-of-code approach, function point model. In this paper, we propose a function-point-based model for estimating software cost. The proposed model is derived by collecting about fifty domestic IT projects in public sector and analyzing their relationship between cost drivers and development effort. Since the proposed model is developed by simplifying the function point model that can be used only when detailed user requirements are specified, it can be also applied at project planning and budgeting phase.

In manufacturing industries, one of the critical issues is to synchronize the sequence of production operations with materials needed at each operation to improve productivity. In order to solve this synchronization problem. We develop a code system entitled 'Work-Order-Number' for automated storage/retrieval systems(AS/RS) in this paper. The Work-Order-Number is designed for the purpose of integrating the engineering information. material handling, production and operations scheduling, point of production, and AS/RS systems. This paper implemented the Work-Order-Number in the electric motor manufacturing. The results of the implementation showed the reduction of the number of workers in material handling and cost-loss due lo a late delivery.

The international sale transaction is in essence a sale of goods and presents all those commercial and legal problems in any sale of goods. As a result, A International sales contract imposes several duties on the parties : the seller must deliver the goods and transfer ownership in them, while the buyer must pay the price and take delivery of the goods. However, there are several problems which impede a active transaction between seller and buyer who have their places of business in other countries each other. Therefore, It is necessary to provide the concept on the conformity of goods in the Int'l Sale of Goods. Especially, In our consideration for the point of time when defects occurs, the existence of non-conformity of goods should be judged on the basis of time of delivery rather than time of contract. Moreover, The burden of proof about nonconformity of goods is another fact which make an international dispute between the contractual parties in an international trade. Thus, The consistency in the interpretation of law must be maintained betweened the warranty and seller's liability. In the Uniform Commercial Code and UN Convention, non-conformity of contract is made of contract liability. And in our civil and commercial law provisions of warranty should be understand as the special ones of the provisions of general non-performance of obligation liability. As a result, More concrete study of them is required because they may have a great influence especially on international trade. As a result, We should be our best in finding a helpful and systematic structure that the dualistic structure of nonperformance of obligation liability and warranty liability must be unified by studying the theories of English and American warranty and our legal system, as well as international practice and usage being used in an international trade.
