Recently, in a field of cadastre, a computerization of cadastral map is in progress with great growth of GSIS field. Also, the needs fer the integration of land and building information are widely increasing for integral-management and its application of various land related information. Through a revision of cadastral laws to replace the existing 2D-Cadastre with the 3D-Cadastre, a legal basis to register the position of buildings and facilities is prepared in the governmental or civil fields. This paper presented 3D-Cadastre theory that has been studied on Europe and surveyed building position directly with Totalstation at cadastral control point after choosing pilot test area, Also, the most efficient surveying method of registering building in a cadastral map is presented with comparing and analyzing building position after surveying digital orthophoto and digital map. And it is constructed a 3D information cadastral map model that can make the integral management of land, building, connecting land recorders, building management ledgers, building titles, building pictures, and related attribute information.

The accurate geo-referencing processes that apply ground control points is prerequisite for effective end use of HRSI (High-resolution satellite imagery). Since the conventional control point acquisition by human operator takes long time, demands for the automated matching to existing reference data has been increasing its popularity. Among many options of reference data, the airborne LiDAR (Light Detection And Ranging) data shows high potential due to its high spatial resolution and vertical accuracy. Additionally, it is in the form of 3-dimensional point cloud free from the relief displacement. Recently, a new matching method between LiDAR data and HRSI was proposed that is based on the image projection of whole LiDAR data into HRSI domain, however, importing and processing the large amount of LiDAR data considered as time-consuming. Therefore, we wmotivated to ere propose a local LiDAR chip generation for the HRSI geo-referencing. In the procedure, a LiDAR point cloud was rasterized into an ortho image with the digital elevation model. After then, we selected local areas, which of containing meaningful amount of edge information to create LiDAR chips of small data size. We tested the LiDAR chips for fully-automated geo-referencing with Kompsat-2 and Kompsat-3 data. Finally, the experimental results showed one-pixel level of mean accuracy.

Background: A chronic disease management program including patient education, recall and remind service, and reduction of out-of-pocket payment was implemented in Korea through a chronic care model. This study aimed to assess the effect of a community-based intervention program for improving medication adherence of patients with diabetes mellitus in rural areas of Korea. Methods: We applied a non-equivalent control group design using Korean National Health Insurance Big Data. Hongcheon County has been continuously adopting this program since 2012 as an intervention region. Hoengseong County did not adopt such program. It was used as a control region. Subjects were a cohort of patients with diabetes mellitus aged more than 65 years but less than 85 years among residents for 11 years from 2010 to 2020. After 1:1 matching, there were 368 subjects in the intervention region and 368 in the control region. Indirect indicators were analyzed using the difference-in-difference regression according to Andersen's medical use model. Results: The increasing percent point of diabetic patients who continuously received insurance benefits for more than 240 days from 2010 to 2014 and from 2010 to 2020 were 2.6%p and 2.7%p in the intervention region and 3.0%p and 3.9%p in the control region, respectively. The number of dispensations per prescription of diabetic patient in the intervention region increased by approximately 4.61% by month compared to that in the control region. Conclusion: The intervention program encouraged older people with diabetes mellitus to receive continuous care for overcoming the rule of halves in the community. More research is needed to determine whether further improvement in the continuity of comprehensive care can prevent the progression of cardiovascular diseases.

Image co-registration is the process of overlaying two images of the same scene, one of which represents a reference image, while the other is geometrically transformed to the one. In order to improve efficiency and effectiveness of the co-registration approach, the author proposed a pre-qualified area matching algorithm which is composed of feature extraction with canny operator and area matching algorithm with cross correlation coefficient. For refining matching points, outlier detection using studentized residual was used and iteratively removes outliers at the level of three standard deviation. Throughout the pre-qualification and the refining processes, the computation time was significantly improved and the registration accuracy is enhanced. A prototype of the proposed algorithm was implemented and the performance test of 3 Landsat images of Korea. showed: (1) average RMSE error of the approach was 0.435 pixel; (2) the average number of matching points was over 25,573; (3) the average processing time was 4.2 min per image with a regular workstation equipped with a 3 GHz Intel Pentium 4 CPU and 1 Gbytes Ram. The proposed approach achieved robustness, full automation, and time efficiency.

As a number of new college students is dramatically decreasing, each college is trying to find various solutions for gathering many students and operating a school. In specialty, information such as entrance examination and matriculation status data is very important for a college to decide a direction of admission and public relations policy, and increase welfare of the school. Therefore, it is seriously needed for a school to introduce a matriculation management system that can do the effective analysis through various entrance examination and matriculation status data and decision factors of school. In this study, I developed a matriculation management system which can analyze information of applicants, successful candidates and registrants based on national framework data, and was able to analyze applicants, successful candidates, registrants by regional groups and the ratio of successful applicants against applicants and the change rate of applicants in the last 3 years. It is expected that the developed system can provide appropriate and rational information for public relations policy and operation to a college.

It has been known that the host mobility feature has very significant impact on the QoS (Quality of Service), which is usually required to a real-time multimedia application. The existing QoS support mechanisms to provide the real-time services to fixed network environment, like as RSVP, are inadequate to accommodate the mobile hosts which can frequently change their point of attachments to the fixed network. So, MRSVP (Mobile RSVP) protocol has been proposed to reduce the impacts of host mobility on QoS guarantees, in which a mobile host needs to make advance resource reservations at multiple locations it may possibly visit during the lifetime of the connection. This paper proposes a dynamic dual anchor node (DDAN) architecture which integrates the MRSVP and RSVP tunnel, in addition to the Mobile IP Regional Registration protocol. By limiting the resource reserved in local area, it preserves the lower level of resource reservation, but provides approximately the same degree of QoS support as the existing MRSVP.

Purpose: This study was conducted to explore the healthcare experience of residents participating in the Community-Based Hypertension and Diabetes Registry Program. Methods: This study used qualitative content analysis. Data were collected from in depth interviews of fifteen participants, who either participated in the program hosted by the Training Center for Hypertension and Diabetes for more than two years or participated in an intensive one-on-one education program. Results: The results showed that the core theme in healthcare of participants was 'Proactive healthcare with attention and systematic guidance of experts'. The positive reinforcement of staffs and the improvement of self-efficacy through effective close management were found to be positive influencing factors of participation. The theme consisted of the following categories: 'Participation in the program with positive expectations on healthcare', 'Interest in body and health', 'Vitality in life', 'Confidence in dealing with disease', 'Thankfulness for close care and attention', and 'Desire for continuous care'. Conclusion: When establishing policies on managing chronic diseases, a strategy that reflects the results of the study is required. It is necessary to build up emotional relationship among stakeholders, and expand opportunities for close healthcare such as one-on-one customized training, and mutual cooperation with various organizations in the local community.

기존의 댐에 대한 연구는 이 치수 및 전력생산, 환경문제와 같은 댐의 전통적인 기능과 그 파급효과에 대한 연구가 주로 진행되어 왔으나 댐의 친환경적 활용방안 및 댐에 서식하고 있는 동 식물 및 생태계에 대한 연구는 상당히 미흡한 실정이다. 특히, 댐 상류지역 및 주변지역에 위치하고 있는 습지는 댐의 수질개선, 희귀 동 식물의 서식처 확보 등과 같은 생태보존, 위락 경관 생태공원 등의 기능을 제공할 수 있다. 이로 인해 댐유역에 위치하고 있는 자연습지의 보전뿐만 아니라 훼손에 따른 대체습지(인공습지)의 필요성이 점증되고 있는 실정이다. 따라서 본 연구에서는 현재 운영되고 있는 댐을 대상으로 댐이 지니고 있는 습지의 역할을 검토하고자 수문지형학적 방법인 HGM 방법을 이용하여 댐습지의 기능을 평가하였다. HGM 방법을 이용하여 댐습지의 기능평가를 수행하기 위해서는 대상습지와 기준습지가 필요하며, 본 연구에서의 대상지역은 댐 유역내 습지지역이 조성되어 있는 보령댐으로 선정하였으며, 기준지역은 보전이 잘 되어 있고 람사르 협약에 등록된 우포늪으로 선정하였다. HGM 방법에서의 기능 평가는 수문학적, 생지화학적, 식물 서식처 그리고 동물 서식처 측면으로 구분하여 대상지역과 기준지역을 비교하는 방식으로 이루어진다. 그 결과, 댐습지가 지니고 있는 습지의 기능이 자연습지에 비해 평균적으로 약 50%정도의 역할을 하는 것으로 나타났다. 이는 댐습지가 습지로서의 역할을 기능적으로 100% 수행을 못하고 있지만, 댐이 습지의 기능을 어느 정도의 수준까지는 수행을 하고 있음을 알 수 있다.

The home nursing care system is an integral part of the health care delivery system in order to meet the various needs of consummer, in particular, early discharge patient from the hospital, patient with long term care needed and the elderly. To find out the cost of home nursing care services, the home nursing care records of patients registered by home nursing care units established in public hospital with 150beds during the period of 1996 - 1997 were analyzed. The subjects were 102patients, 45 of male patients and 57 of female patients, those who live in a rural area in Kymiggi - Do The results obtained are as follows : 1. The male patients accounted for 44.1% of the total, with 45cases : group aged 60 years and more was the largest group, accounting for 79.5%. 2. The most frequent disease revealed was the osteoporosis which constitute 35.3% of the total registered patients, followed, in order, by malignant tumor, cerebrovascular disease. 3. It revealed that the cost per visit for the male was 47,764won ; the female, 46,078 won per visit. Noteworthy the cost per visit was high in the older patient. It was clearly that the gender, years of age and the cost per visit were statistically significant at 0.01 level and 0.05 level. 4. The cost per visit for the non complicated disease was slightly higher than the complicated disease, but it is not statistically significant, the cost per visit by type of disease varied, the cost per visit for COPD was the highest, followed, in order, by in malignant tumor, cancer, diabetes, osteoporosis etc. 5. It revealed that home nursing care cost for a eligible disease for home nursing care was less than the cost for hospitalization of the same disease, therefore, we expect that the home nursing care is cost efficiency. In conclusion, the home nursing care costs are needed to analyze further in comparison with the hospitalization costs for a certain disease.
