본 논문에서는 호의 도착을 고려한 거리기준 위치등록 방식을 제안하고 성능을 평가하였다. 이를 위해 이동성 모형을 제시하고, 이를 이용하여 제안한 방식의 성능을 분석하였다. 분석 결과 거리기준 위치등록 방식은 영역기준 위치등록 방식에 비하여 위치등록이 자주 발생하지만 위치등록 부하가 위치영역 내 모든 셀에 분산된다. 반면에 호의 도착을 고려한 거리기준 위치등록 방식의 위치등록 부하는 영역기준 위치등록 방식과 비슷한 수준이면서도 위치등록 부하가 위치영역 내 모든 셀에 분산되기 때문에 한정된 무선자원을 효율적으로 사용할 수 있다.

1.Objectives of the Study It is a well known fact that a prompt and reliable data on demographic information is essential in a proper planning and evaluation of any program of national or community level. Especially vital statistics are an important demographic component among demographic information. Realizing the importance of vital statistics, the government has made some efforts for years to improve the vital registration system which has a close relationship with the production of vital statistics. However, it is still observed that there are some limitations in utilizing vital registration data due to considerable amount of vital events which are never registered and registered but not in time or inaccurately, even though vital registration system in Korea has sound legal basis. In this connection, the objectives of the study is as follows :(1) To examine some problems of the vital registration system in various aspects, (2) To make improvement programme of continuous Demographic Survey as a supplementary source of vital statistics, and (3) To find out some alternatives for making it possible to produce and utilize the reliable vital statistics by developing analytical methodologies on that. 2. Current Situation of Vital Registration System All the vital events, i.e. births, deaths, marriages and divorces, are to be registered in time under the Civil Registration Law, Statistics Law and Regulation on Vital Statstics as a duty of people. Some recent tendencies in each of recent registration are summarized as below: (1) The completeness of vital registration .Out of all births which are occurred during a year, around 75% of those compared to the estimates are registered in the year of occurrence. .In case of death registration, the percentage of registration in the year of occurrene has been gradually increased from 86.2% in the year of 1980, but it is still below the level of 90% compared to the estimates. .The percentage of registration for marriages and divorces in the year of occurrence out of total registered numbers was revealed to be 69% and 73% respectively in 1985. (2) Continuous Demographic Survey .It is a kind of sample survey for the purpose of producing reliable vital statistics which could not be provided by the vital registration. .It covers about 17, 000 sample households at national level and important information for vital events are collected in every month by 323 expertized enumerators who are regular staff of the government. .Although the result of the survey seems to be more reliable than of vital registration, the reliability of the data is still bellow the acceptable level if compared with relevant information from other sources such as population census or special surveys. 3. Problems of Vital Registration System There are four major obstacles in improving vital registration system in Korea; (1) In general, policy priority is not given on any programme of improving vital registration system. It is, therefore, very difficult to formulate comprehensive programme through having cooperation from related authorities and sufficient financial assistance. (2) In all the laws related and system itself, there is substantial degree of overlap and irrationality. Registration of each vital event is maintained according to several laws and regulation such as Civil Registration Law, Statistics Law, Resident Registration Law and Regulation on Vital Statistics. However they are mutually overlapped and overall supervision can not be done systematically due to lack of co-operation among the authorities concerned. (3) The administration of vital registration system seems to be working inefficiently, because of most of civil servants who are in charge of vital registration are lacking of conception on vital statistics and also there is a certain extent of regidity in handling the works. Therefore, they are doing their jobs in a passive way. (4) A substantial proportion of vital events occurred is not registered within the legal time limit (i.e. within one month after the occurrence in case of birth and death) or not registered forever. Some of social customs and superstitution seem to be the potential causes especially in case of births and deaths. 4. Recommendations for the Improvement of Vital Statistics (1) Reporting systems such as civil registration, vital statistics and resident registration should be integrated under the single law. Also, administrative supervision, personnel and budget with regard to the registration system should be under the control of a single ministry. (2) It is necessary to simplify the procedures and methods of reporting vital events, i.e., reducing number of sheets of the form, making corrections easily, reducing registration items, etc. (3) Continuous Demographic Survey as a supplementary source of vital registration should be improved and special ad-hoc surveys should be conducted wth regular interval. (4) In-depth analysis should be done using various sources of data on vital statistics. 5. Concluding Remarks From this study, we can notice that temporary campaign and motivation programs are not sufficient to improve the quality of vital statistics. Strong intentions and continuous efforts of the government are needed for the improvement of the vital registration system. Furthermore, most of the data collected through the registration are not properly analyzed and utilized, partly due to the lack of appreciation among high-level governmental officials of the need for vital statistics. It is, therefore, requested that long-term improvement programs of vital statistics be implemented with policy priority and continuous efforts be given to this purpose as a long-term goal of development in Korea.

In this paper, we evaluate the performance of zone-based registration. First, we propose a mobility function for single zone-based registration. And we establish the circumstances of multiple zone-based registration, which is based on the mobility function for single zone-based registration, and perform simulation programs for the circumstances. Using the simulation results, we obtain optimal N, the number of multiple zones which minimizes signalling traffic in radio channels. Results show that in most cases optimal N is 2. Multiple zone-based registration has less signalling traffic in radio channels than single zone-based registration and zone-based registration must be implemented as multiple zone-based registration.

The Korean resident registration number has been used since 1962 as a personal identification number. The Korean government assigns this number to each korean citizen and it is not able to be changed. In 2000s, as the Internet was rapidly spreaded out, personal information such as the Korean resident registration number, name, home address, and phone number was leaked. The companies provide diverse internet service while collecting personal information. However, personal information was sometimes leaked because of hacking, poor information management and so on. As s results, some of citizens asked government and court of Korea to change the Korean resident registration number because they suffered material damage and emotional distress. The constitutional court decided to be able to change the number from 2018. In this study, the Korean resident registration number which is possible to change, serial number, public certificate, I-PIN, and My-PIN were analyzed comparatively. In addition, considerations when the Korean resident registration number was changed were discussed. The public certificate and I-PIN were appropriate to the case of on-line Korean resident registration number. The Korean resident registration number, serial number, My-PIN were appropriate to the case of off-line Korean resident registration number. Lastly, it would be efficient to manage the Korean resident registration number separately such as on-line and off-line.

For small image registration, feature-based approaches are likely to fail as feature detectors cannot detect enough feature points from low-resolution images. The classic FFT approach's prediction accuracy is high, but the registration time can be relatively long, about several seconds to register one image pair. To achieve real-time and high-precision rigid registration for small images, we apply deep neural networks for supervised rigid transformation prediction, which directly predicts the transformation parameters. We train deep registration models with rigidly transformed CIFAR-10 images and STL-10 images, and evaluate the generalization ability of deep registration models with transformed CIFAR-10 images, STL-10 images, and randomly generated images. Experimental results show that the deep registration models we propose can achieve comparable accuracy to the classic FFT approach for small CIFAR-10 images (32×32) and our LSTM registration model takes less than 1ms to register one pair of images. For moderate size STL-10 images (96×96), FFT significantly outperforms deep registration models in terms of accuracy but is also considerably slower. Our results suggest that deep registration models have competitive advantages over conventional approaches, at least for small images.

2015년 12월, 헌법재판소는 주민등록번호 변경이 불가능하도록 한 주민등록법에 대해 헌법불합치 선언을 하고 2017년까지 개정을 하도록 했다. 본 연구에서는 개인정보보호와 관련되어 문제가 되고 있는 주민등록번호제도의 변경방안과 변경방안을 둘러싼 중요한 쟁점사항들에 대해 살펴보고, 이에 대한 일반 국민들의 인식조사를 수행하였다. 설문조사 결과 국민들은 자율적으로 번호를 변경하기를 바라고 있으며 개인정보가 주민등록번호 상에 나타나지 않기를 선호한다. 그리고 주민등록번호 외에 분야별로 별개의 번호를 사용하는 것에 대해 긍정적으로 보고 있다. 하지만 주민등록번호 개편에는 불편 비용이 소요될 것으로 인정되고 있으며, 이러한 불편 비용에 대해 국민들은 개별적으로 부담할 의사가 적었다. 즉 국민들은 주민등록번호 개편에 대해 긍정적이고 그 필요성을 인정하고 있음에도 불구하고 그에 대한 비용을 부담하지는 않으려는 경향이 강하다고 볼 수 있다. 이러한 연구 결과는 주민등록번호 개편 방향, 그에 대한 국민의 선호, 그리고 국민들이 주민등록번호를 변경하면서 어느 정도의 불편을 겪을 것인가 하는 것에 대한 기초적 연구가 될 수 있다.

종래의 판례에 의하면 사해행위인 매매예약을 원인으로 가등기를 마친 수익자가 그 정을 모르는 제3자에게 가등기에 의한 권리를 양도한 후 가등기 이전의 부기등기를 마치게 해 주고, 그 제3자가 그 가등기에 기한 본등기를 마친 경우에 있어서 수익자는 가등기말소등기 청구소송의 상대방이 될 수 없다고 보았다. 그 결과 수익자의 원상회복의무의 면탈 행위를 용이하게 해 줄 수 우려가 항존하고 있었다. 이에 대해 대상판결이 종래의 견해를 변경하여 수익자에게 피고적격을 인정함으로써 수익자를 상대로 사해행위인 매매예약의 취소를 청구할 수 있다고 판시한 것은 매우 바람직한 것으로 생각된다. 또한, 대상판결이 등기 명의인의 동일성이 인정되지 않는 위법한 경정등기가 마쳐졌다 하더라도, 그것이 일단 마쳐져서 경정 후의 명의자의 권리관계를 표상하는 결과에 이르렀고 그 등기가 실체관계에도 부합하는 것이라면 그 등기는 유효하다는 입장에서 경전 전 등기명의인의 권리관계가 소급적으로 소멸하지 않는 것으로 보아 이 사건 매매예약에 관한 사해행위 취소권자인 원고에 대하여 여전히 수익자의 지위에 있어 이들에게 사해행위 취소소송의 피고 적격이 있다고 판시한 것 역시 의미가 있는 것이라 생각된다.

In this paper, new filtering method for sensor registration is provided to estimate and correct error of registration parameters in multiple sensor environments. Sensor registration is based on filtering method to estimate registration parameters in multiple sensor environments. Accuracy of sensor registration can increase performance of data fusion method selected. Due to various error sources, the sensor registration has registration errors recognized as multiple objects even though multiple sensors are tracking one object. In order to estimate the error parameter, new nonlinear information filtering method is developed using minimum mean square error estimation. Instead of linearization of nonlinear function like an extended Kalman filter, information estimation through unscented prediction is used. The proposed method enables to reduce estimation error without a computation of the Jacobian matrix in case that measurement dimension is large. A computer simulation is carried out to evaluate the proposed filtering method with an extended Kalman filter.

With the development of medical imaging technology, image registration has been widely used in the field of disease diagnosis. The registration between different modal images of brain magnetic resonance (MR) is particularly important for the diagnosis of brain diseases. However, previous registration methods don't take advantage of the prior knowledge of bilateral brain symmetry. Moreover, the difference in gray scale information of different modal images increases the difficulty of registration. In this paper, a multimodal medical image registration method based on image segmentation and symmetric self-similarity is proposed. This method uses modal independent self-similar information and modal consistency information to register images. More particularly, we propose two novel symmetric self-similarity constraint operators to constrain the segmented medical images and convert each modal medical image into a unified modal for multimodal image registration. The experimental results show that the proposed method can effectively reduce the error rate of brain MR multimodal medical image registration with rotation and translation transformations (average 0.43mm and 0.60mm) respectively, whose accuracy is better compared to state-of-the-art image registration methods.
