Place names are generally composed of first half and second half, whether the originality of those names comes from Korean or Chinese. The first half, modifying the second half, represents the naming flexibility of the name, while the second half of the name points out its directive object, which refers to a branch of the name. For example, 'Myeong' in 'Myeongryang' and 'No' in 'Noryang' represent their naming flexibility while 'Ryang', constituting the second half, points out the name's directive object. The purpose of this study was to investigate the etymology of place names, 'Myeongryang' and 'Noryang', by figuring out the meanings of those two elements. In order to search for the meaning of the second half, 'Ryang', other examples presented in the related literature have been examined. The finding indicated that 'Ryang' means 'dol', or 'do', which refers to 'moon(door)'. Furthermore, it is found out that the meaning of 'Ryang' has been transferred from 'dol' or 'do' to 'moon(door)', furthermore, to the straits. Upon looking into the origins of those names on the field, it is interpreted that 'Myeong Ryang' has been meant as a door in which huge and rough waves cry out, and 'No Ryang' has been meant as a door in which huge and rough waves rise up.

Social networking services that connect a person to other people are attracting our attention and various types of on-the-network services are provided. Library has been playing a role of social media by providing with materials such as books and magazines, and with a place for reading, studying, getting lectures, etc. In this paper, we present a method for finding candidates of groups of the library's patrons who share interest areas by utilizing the loan records, which are obtainable by every library. Such a homogeneous group can become a candidate for a study group, a community for exchange ideas, and other activity group. We apply the method to a collection of loan records of a university library, find some problem to be solved, and propose measures for more detailed solutions. Even though the potential group finding problem still remains a lot of problems to be solved, its potential importance is very high and thus to be studies even more for future applications.

The paper discusses the problem of finding the Origin-Destination(O-D) shortest paths in internodal transportation networks with time-schedule constraints. The shortest path problem on the internodal transportation network is concerned with finding a path with minimum distance, time, or cost from an origin to a destination using all possible transportation modalities. The time-schedule constraint requires that the departure time to travel from a transfer station to another node takes place only at one of pre-specified departure times. The scheduled departure times at the transfer station are the times when the passengers are allowed to leave the station to another node using the relative transportation modality. Therefore, the total time of a path in an internodal transportation network subject to time-schedule constraints includes traveling time and transfer waiting time. In this paper, a genetic algorithm (GA) approach is developed to deal with this problem. The effectiveness of the GA approach is evaluated using several test problems.

Recently, the definition of work space contains so many meanings. Basically, this means space where handling various information and developing numerous creative activities. Moreover, the work space is important not only for individual itself but also organizational development. This research is studied for suggesting revitalization of advanced work efficiency, deriving motivation as well as creative operation support for harmonious communication. In order to make the better creative work places, "concentration and motivating interests between members of organization", "Necessity of environment for development and operational progress of work", "improvement and creativity of work and importance of the physical environment" and "harmonious communication and development of advanced community" should be considered. This research arranged based on ALCEMIS model and used actual examples on each step for better understanding of creative work spaces. ALCEMIS model is as follows: (1) Opportunity Finding (2) Fact Finding (3) Opportunity Definition (4) Idea Finding (5) Evaluate & Select (6) Plan (7) Acceptance (8)Execution' over the eight-step details to proceed through the 1. Discovert ((1)+(2)) 2. Dream ((3)+(4)) 3. Design((5)+(6)) 4. Destiny((7)+(8))y" It has been understood that many works related to creative jobs make good use of public spaces to progress operational improvement. The place where co-workers share with can create more effective and fulfilling outcome and satisfaction than independent and exclusive places. Especially creative jobs need this kind of spaces for better communication and cooperation.

We analyse the map of the west capital Pyongyangbu of Old Korea(AD 920) by topological method and geometrical method and compare it with the map of North Korea Pyongyang. By the analyse of the map we find the real place of the old map. The analysing and finding the real place of the old map is a very good example of geometry education. Many Koreans had learned and recognized that Old Korea(AD 920) was a small country located in the south part of Ablok river. But, after reading this paper they change their old recognitions and they take prides in Great Old Korea.

Fire-fighters are struggling against heat and dense smoke by fire when it occurs at the basement or the inner place of a building. An indoor fire-fighting robot with well heat-resistance, great searching cameras and good extinguishing ability has been developed. It never suffocate, coming into the fire district and extinguishes fire directly. In this study, several experiment was conducted to evaluate field working ability of the fire-fighting robot. As a result, a series of passing obstacles, finding fire place and fire suppression by the remote controlling with image information appeared satisfactory.

The interaction of oxygen molecule with Ni44(111) model surface to which the molecule approaches is studied by calculating the relevant DOS and COOP with the tight-binding EHT method. It is found that the dissociative adsorption of oxygen takes place as a result of electron transfer from the Ni d${\pi}$ orbital to the antibonding 1${\pi}_g$ orbital of the oxygen molecule. This finding is noteworthy to contrast with the case of Ni(100) surface in which the electron transfer takes place from the Ni d${\delta}$ orbital of the nickel surface.

The purpose of this note is to give insights into the role of parallelism to the middle school mathematics. According to NCTM(1998), the middle grades mathematics classroom should be a place in which students regularly engage in thoughtful activity that relates to their emerging capabilities of finding and imposing structure, conjecturing and verifying, and engaging in abstraction and generalization. In this aspect it is desirable to reinvestigate Euclidean Parallel Postulate in the axiomatic point of view in the level of the middle school mathematics. Reconstructing the contents Greenberg(1993), and we explain the statements which are logically equivalent to the Parallel Postulate for mathematics teachers in the middle school.

Libraries both in the East and the West in terms of its usage went through various changes in meaning. The writer attempted an etymological study on the terms of libraries from the earliest time to the present time. Finding various ways and means of usage in the literature of past and present, the writer tries to suggest the best fitted term for libraries to the Korean usage. The suggestion which the writer intended to introduce is Munhun-gwan(文獻館) in the place of Dosu-gwan(圖書館).
