This paper proposes OPTICAL MARKER fer registering process - one of the 3D measurement process : scan registering - merging - measurement. If the registering work is carried out manually, it can be accompanied with much time and many errors. Because the patterned marker make registering process automatic, many firms use it now. But the physical shape of existing markers is the source of the data loss caused by hiding surface, and the marker arrangement is the source of the time loss. The optical marker proposed in this paper has marker generator, organized a large number of binary coded control laser diode, separate from 3D scan object. So, it does not take much time for the marker disposition, and it is not the origin of the data loss, and the binary coded laser information make the auto-registering possible.

Transforms including translation and rotation are required for registering two or more images. In medical applications, different registration methods have been applied depending on the structures: for rigid bodies such as bone structures, affine transformation was widely used. In most previous research, a single transform was used for registering the whole images, which resulted in low registration accuracy especially when the degree of deformation was high between two images. In this paper, a novel registration method is introduced which is based image sub-division and bilinear interpolation of transformations. The proposed method enhanced the registration accuracy by 40% comparing with Trimmed ICP for registering color and MRI images.

The Antarctica continent does not belong to any countries so that a place in the region has some different place names between countries. Korea gave Korean place names to the places around the King Sejong Station, and the names have since been used by Korean researchers on the Antarctic. However, they have yet to be registered officially at CGA(Composite Gazetteer of Antarctica) by November 2010. Therefore, to prepare for the possible disputes over territorial claims in Antarctica and to expand and specify activity areas, this research tries to analyze the present condition of advanced countries' committees on place names of Antarctica, their procedures of registering names and their registration criteria, and thereby suggest an efficient plan for registering place names of Antarctica. If the plan suggested in this research is actively reviewed and applied, it will be able to make a great contribution to advancing the place names of Antarctica and research on the Antarctic.

Since the idea of registering architectural heritage from the early 20th century was introduced as part of the code in the Cultural Heritage Protection Law in July, 2001, more systematic and flexible application the code has been in great demand. It is the aim of this thesis that we preserve modern buildings and then use this research data what find our modern history. So we should find connection of modem and tradition with the overcome of the feeling of being victimized. Accordingly, based on preservation cases and finding of modern house heritage, it is the aim of this thesis that we find the way of the best use. The purpose of this research is to establish a more comprehensive and commonsensical guideline for the preservation of modern architecture satisfying both the government and the registering party, based on more thorough architectural analysis of residential edifices. The results of this study were as follows: (1) It is necessary for application and conservation by point, area and network method. (2) It is needed that periodically check and record central system for the purpose of the management of those. (3) It's consider that develop of conservation method on co-ownership with citizen by house personality.

Drones are increasingly being used to investigate disaster damage because they can quickly capture images in the air. It is necessary to extract the damaged area by registering the drones and the existing ortho-images in order to investigate the disaster damage. In this process, we might be faced the problem of registering two images with different time and spatial resolution. In order to solve this problem, we propose a new methodology that performs initial image transformation using line pairs extracted from images and association matrix, and final registration of images using linear features to refine the initial transformed result. The applicability of the newly proposed methodology in this study was evaluated through experiments using artifacts and the natural terrain areas. Experimental results showed that the root mean square error of artifacts and the natural terrain was 1.29 pixels and 4.12 pixels, respectively, and relatively high accuracy was obtained in the region with artifacts extracted a lot of linear information.

This study was done in order to analyze the factors which influenced the performance level of urban family planning health personnels' task. Interview survey was done during the period May, 1989. Interviewee were 130 family planning health personnels among total of 140 family planning health personnels in Seoul metropolitan city area. The internal consistency reliability was tested by Cronbach’s Alpha and the construct validity of the survey tool was tested by Factor analysis. Multiple stepwise regression analysis was used to identify major factors influenced to perform family planning health personnels' task. The results of this study were summarized as follows: 1. The internal consistency reliability was high and very significant (Cronbach's Alphs=0.8445, p<0.0000). 2. The construct validity was high and very significant. This analysis was contained 5 factors; registering and keeping of eligible woman records, health educating for FP & MCH, referral for vasectomy and tubal ligation and loop, supplying contraceptive appliances, sending moved-out eligible woman records. 3. Among a total of 15 contents of their functions recording of daily report and monthly report (76.2%), classifying and keeping of records(66.2%), registering of eligible woman records(60.85ti), distribution of leaflets and pamplets(54.6%), counselling & supervision about family planning(53.8%) were actively performed. Sending moved-out eligible woman records(60.8%), health education for community people(49.2%), referring contraceptors' side-effects were poorly performed. 4. The factors which influenced the performance level of urban family planning health personnels' function were age, marital status, educational level, certification, number of residents, number of eligible women, job car-eer, work responsibility, job satisfaction knowledge, position, cooperation of community people, cooperation of Dong Office, cooperation of Health Center. These 14 variables were able to explain job function from 21.4% of follow-up care of contraceptor to 9.1% of classifying & keeping of eligible woman records.

With rapid spread of handheld devices like cellular or smart phones, a short message service (SMS) comes on the public as a communication means. SMS is very cheap and can be easily written down on the storage in order not to forget it, hence it is widely used to inform schedules (time and place). In this paper, we develop a system for automatically registering schedules extracted from SMS text messages. SMS text messages are very short and concise, but include a lot of Internet words like slangs and abbreviations. These have made it difficult to extract information on schedules from them. Also handheld devices have some limitations on computing power and storage and then applying general natural language processing modules like morphological analysis to the devices are somewhat hard. To relax these burdens, we extract schedule informations from SMS messages using machine learning methods like condition random field (CRF) without using any language processing modules and register the informations on the schedule management system of handheld devices. Our proposed automatic schedule registration system has implemented on Samsung Omnia phone for experiments.

Since textbooks are developed according to the curriculum, it might be said that the terms registered in curriculum can serve as guidelines for terms used in textbooks. But it really is not. In this study, so that terms registered in curriculum can serve as guidelines for terms used in textbooks, inconsistencies between them would be found out and improved. To this end, suitability of selecting and using terms are discussed, focusing on terms registered in curriculum and terms used in textbooks. In fact, there are significant differences between the terms registered in curriculum and the terms in textbooks, because there is not any criteria in selecting and using terms. In this study the five criteria with respect to registering terms in curriculum are proposed. Everyday language should not be registered. Naturalized terms should not be registered. Terms used in only elementary mathematics, but are already well-established should be registered. Same term used in diverse context should be registered only once. Terms which can be used without definition should be designated. Three criteria in regard to using terms in textbooks are proposed. Terms registered in curriculum must be used. Same term used in diverse context should be redefined in every context. Terms that are not certified and are not absolutely necessary must not be used.

Through the technology of the 4th industrial revolution, agricultural machinery is becoming increasingly intelligent, and the machine is replacing the role of farmer manpower as a whole. However, safety accidents caused by careless use of agricultural machines and theft accidents due to the difficulty of keeping them are increasing every year. Because agricultural machines do not manage the history of events and accidents unlike automobiles, they are often used for crime. There is also no way to cope with the issues if there happens issues on agricultural machines. In this paper, we propose the system based on block chain which can manage the history of the agricultural machinery by registering the chassis number at the same time when purchasing the agricultural machinery. Since this system contains the history of accident and repair information about the owner's agricultural machinery, it is possible to trace back even if a theft occurs. The proposed system also allows buyers to secure transactions by providing reliable data through inquiry of this system when trading in the secondary market in the future.
