It is difficult to obtain the accurate and homogeneous height information over the whole Korea due to the effect of different vertical datums have been divided into land and sea part. In this study, we tried to unify the different vertical datums using the precise spirit leveling between TBM (tidal bench mark) and BM (bench mark) in order to solve the problems caused by different vertical datums. For this, the vertical datum offsets at observed points which were calculate from leveling results and then transformation model of vertical datum will be modelled using calculated offsets along the coastal line. For suggesting the precise modelling method to vertical datum transformation, we analyzed results from various interpolation methods such as Spline and LSC method. As the results from analysis, the LSC method combined with 4-parameters trend model is more suitable for modelling the offsets between vertical datums. The final transformation model of vertical datum using the combination of LSC and 4-parameter model which provides the transformation accuracies of ${\pm}10.4cm{\sim}14.8cm$ level. And, the software for vertical datum transformation that was also developed using the final model in order to convert the height information included in various spatial data effectively. Therefore, the transformation model between vertical datums of land and sea part, which is developed in this study, is expected to minimize the confusion caused by mismatch of height information in the use of spatial data, and it also can be minimize economic and time losses in various application fields such as coastal development project, coastal disaster prevention, etc.

This study looks at plans for the efficient functions of the current terror response system in Korea. The results are derived from by comparing and analyzing American, British, German, Japanese, and Korean terror response systems. It focuses especially on addressing some problems with Korea's terror response system and how to operate it effectively. The study will systematically compare and analyze each nation's terror countermeasure studying organizational, functional, and legal aspects as standards. This study shows that there is not an exclusive terror response center in Korea compared with other nations such as America, the United Kingdom, Germany, and Japan. Also it is difficult to expect effective and vigorous operations due to weak cooperation across the relevant organizations. The presidential directive of the state's anti-terrorism action guidelines is legally ineffective. This means that on legal grounds, it is difficult to take actions to prevent the terrorism. Therefore, keys to counteracting terrorism derived from this study are summarized below. In the first place, an integrated terror response system should be set up for expansion of information sharing which leads to emergence effect. In the second place, the superior legislative systems should be made for the cleardefinition and extent of what the terror is, rigid enforcement of investigation, immigration, and keeping an eye on the funds raised by terrorists and tracking down the terrorists, the plan for eco-terrorism. In the third place, to augment security of vital facilities and peoples' awareness of terrorism safety should be emphasized and a cooperative system between civil and government organizations need to be built. In the fourth place, system for crisis management must be provided in an effort to maximize management system of terrorism and unify a decentralized emergency countermeasures effectively.

South Korea is currently facing multiculturalism, appropriately demanding broadened view and access to the study of Unification, especially in terms of who should be the subject. In congruence, recent Unification Education studies are proposing values stressed in Multiculturalism to function as the core ground, upon which other traits and contents are to follow. Similarly, Christian Education field is also reflecting the recent trend, welcoming 'everyone' to participate in preparing reunification of Korean Peninsula. However, most studies consist of suggesting and introducing directions for new approaches, not so much of dealing with systems or guidelines for practical practices. Information provided in fragments can rather cause confusion in understanding the concept, and lack of specific guidelines can soon lead to poor performances. In this study, Universal Design for Learning (UDL) is introduced as a methodology to be examined, whether it could effectively embody and systemize the newly emerged Multicultural Christian Unification Education. Therefore, the purpose of this study is 1) to generalize the concept of Christian unification education introduced in the multicultural era and 2) examine whether UDL is suitable for uniformizing and spreading the Multicultural approach of Christian Unification Education. Specifically, this study highly focused on examining whether UDL is a suitable methodology to achieve the goal of Multicultural Christian unification education, while uniformizing the diversities within multicultural Christian Unification Education. Through a thorough research, it was proved that the purpose and characteristics of multicultural Christian unification education are similar to those of UDL in that both focus on accepting heterogeneity as something "different" rather than something "wrong." Also, it was found that the application of the theory and guidelines of UDL can effectively unify while respecting the diverse methodologies used in Multicultural Christian Education.

Background : The necessity of unify and standardize codes used at hospital has been emphasized since OCS (Order Communicating System) was adopted. Therefore, the purpose of this study were to standardize operation code by continuous training of the ICD-9-CM code that is used as standard code in OCS program at operating room. Method : In 400 operation data, operation code entered in OCS program at operating room was compared to operation name recorded in medical record. In addition, a matching rate between input data of operation code by medical record department and computing input data of operation code in 3,710 cases was compared for each department. User operation name and operation code were matched and major diagnosis by operation department and operation name were also matched. Results : User operation name was reflected in operation classification code in detail, and operation code entered on user was registered. Input rate and matching rate of operation code were gradually improved after improvement activity. In particular, a matching rate was high at ophthalmology where operation name is segmented. Plastic surgery and orthopedics with a lot of emergency operation and comprehensive operation name show low input rates. Conclusions : As the medical field makes progress in computerlization, awareness of information exchange and sharing becomes higher. Among codes to classified medical institution, codes related to surgical operation are all different by user of hospital and department. Computerlization and standardization is essential. And when efforts of standardization continue in alliance with individual hospital and institution, initiative of preparing medical policy data at a national level will be accelerated.

This is a comparative and analytical study which comprises of the analysis of the rules of the buyer's remedies where the seller delivers defective goods of four legal systems; Directive, CISG, English law and Korean law. In light of threefold main purposes of this study, it firstly attempts to describe and analyze the remedy provisions of Directive in a comparative way in order to provide legal advice to the sellers who plans to enter into English consumer markets. It shows that the two tier remedial system under Directive is not much different from the other jurisdictions, except where the right of rescission under Directive is absolute in a sense that it does not require a certain degree of seriousness of defect. Secondly, the study compares the rules of one jurisdiction with those of other jurisdictions and evaluates the rules in light of the discipline of comparative law the basic question of which is whether a solution from one jurisdiction may facilitate the systematic development and reform of another jurisdiction. It proves the followings; (1) the reluctance and uncertainty in English law of ordering specific performance based on the discretionary power does not reflect the parties' preference because the order is either uncertain or rather negative where the purchase of substitute goods elsewhere is not a satisfactory solution in many cases; (2) the position in Korean law which has no limitation on the right to require substitute goods is likely unfair in commercial sales, but justified in consumer sales; (3) the right of termination or reduction under Directive which is subject to the applicability of the right to require repair or substitute goods seems to be contrary to the consumer's preference where the defective delivery destroys the basis of trust in the quality of the seller's performance; (4) the absolute right of termination under Directive and English law seems crucial in consumer sales because they are often inferior to commercial sellers in terms of information and bargaining power; (5) the right of reduction as a self-help remedy which is absent in English law emphasizes its usefulness. Thirdly, it finds that, where CISG is deemed to fail to unify different rules on the right to require specific performance between Civil and Common law, it is attempted once again in Directive and notwithstanding their hostility to awarding the right to require specific performance in English law, Regulations 2002 expressively stipulates such right.

Recently data centric routing or application dependent routing protocols are emerged in mobile ad hoc networks. In this paper, we propose a routing method for query processing in MANET(Mobile Ad hoc NETwork) environment, called road-based query routing, with consideration on real time traffic information of large number of vehicles. In particular, we focus on the method that process arrival time dependent shortest path query in MANET without a central server on the road networks. The main idea of our approach lies in a routing message that includes query predicates based on the road connectivity and on data gathering method in real time from vehicles on the road by ad-hoc network. We unify route discovery phase and data delivery(query processing) phase in our mechanism and reduce unnecessary flooding messages by pruning mobile nodes which are not on the same or neighboring road segments. In order to evaluate the performances of the proposed method, we established a model of road networks and mobile nodes which travel along the roads. The measurement factor is the number of nodes to whom route request is propagated according to each pruning strategy. Simulation result shows that road information is a dominant factor to reduce the number of messages.

This paper discusses a method of selecting variant groups to be reviewed for LGR (Label Generation Rule) of Internet Top-Level Hanja Domain. The most difficult problem in setting up LGR of Internet Top-Level Hanja Domain is how to treat Hanja variants. If domains containing variants (e.g.: 東海國) are directed to different addresses, confusion will arise. Therefore, it is desirable that such domains are directed to the same address. Since variant groups of Korea and China are not same, we need to unify variant groups of Korea and China. In the process of reviewing 3093 Chinese variant groups, the author found that Korea does not need to review Chinese variant groups which include no or just one Korean Hanja character. Korea only need to review Chinese variant groups which include two or more Korean Hanja characters. By doing so, the author could reduce the number of Chinese variant groups to be reviewed by Korea from 3093 to 303, which is only one-tenth of the original number of Chinese variant groups. After Korea finishes reviewing 303 Chinese variant groups selected according to the method suggested in this paper, the job of setting up LGR of Internet Top-Level Hanja domain will be accelerated by negotiating with China.

Geographic information and surveying products are a momentous national infrastructure since it is an essential basis for land management and environmental preservation. Hence, it is necessary to set up a systematic plan and countermeasure for the upcoming unification of Korea. Otherwise there would be tremendous confusion and it will cause enormous expenses to establish the national surveying and geographical information standard. In order to show the vision of policies preparing for the unification of North and South Korea, we analyzed the case of Germany and the current status of surveying and Geographical Information in South and North Korea by taking the internet investigation, having a seminar, interviewing experts, and visiting related organizations. First of all, we should predict the change of surveying circumstances after the reunification and establish a plan that unifies laws, systems, and surveying standards of North and South Korea. We need to modify the datum point and unify the surveying product of South and North Korea in World Geodetic System. To accomplish these goals, we must make the map of Korean peninsula and neighboring nations, especially urban area of North Korea. It is considered that National Geographic Information Institute should take a major role in the unification of Korea. With these active preparations and plans, we will achieve the goals of establishing the reinforced surveying policy and minimizing the reunification expenses.

The SSTop (Sea Surface Topography) provides an estimate of the large scale structure of the deviations between the geoid height and the mean sea surface in terms of a normalized surface spherical harmonic series. The SSTop is the key information which has been used to determine the shape of earth, geoid, current and tide etc. Also, the SSTop is a basic source for the unification of vertical datums at the different height systems which were established according to the their respective purposes. In order to unify the vertical datum around the East-Asian (E-A) region (covers the area: $20^{\circ}-45^{\circ}N$ and $110^{\circ}-140^{\circ}E$), we estimated the value of SSTop in the E-A region using the predicted values of mean sea surface (from KMSS04) and geoid height (from EGM96 and EIGEN-GL04C) and analyzed to aspect of SSTop at 5 tidal stations (InCheon, JeJu, QingDao, Aburatsubo, KeeLung) with the estimated values of each station previously. The result from this study indicates that the SSTop in the E-A region is relatively stable except for the area around the Japanese and Ryukyu deep, and also shows that the distribution of values of SSTop is ranged from 40 to 60 cm at tidal stations except InCheon station.
