Unfortunately, we have poor knowledge of medical technology in North Korea. This study has thus attempted to identify the level and status of medical technology development through analyzing the contents of medical textbooks currently in use. This study has assumed that three factors are influencing the level and status of medical technology in a society ; the level of socio-economic development in general, the level of scientific technology revolution and health policy. Forty textbooks are collected for this purpose. The main findings are summarized as follows : 1) North Korea s strengths in that (1) its herb drugs, which are in a broad use, are cheaper, more safe and more attainable than bio-equivalent chemical ones, and (2) the development of its medical technology was carried out with emphasis on the practical and basic health needs. 2) North Korea has weaknesses in that (1) its medical diagnostic method largely depends on manual procedures, (2) the R & D investment in the development of chemical drugs, especially antibiotics, is very small, (3) the amount of medical equipments is in a absolute shortage, and (4) the medical technology is destitute of specialty, caused mainly by the overemphasis on Juche-Uihak or herb medicine. 3) Medical technology has two faces, positive and negative so that it cannot be successfully evaluated by one. It eventually acts a positive function for public health through developments of drug, equipment and new medical treatment method. But it is also true that it has negative effects such as the dehumanization of high cost medical technology, cost hike due to over-investments in expensive equipment and the absence of wholistic care from overspecialization. 4) We have to consider economic status and the social needs of medical care in order to evaluate the medical technology of a society. It is also the case with North Korea. A whole picture of the North Korean medical technology could be understood only if further comprehensive studies of medical technology are to be carried out for North Korea.

Background: Immunization has been one of the most effective measures preventing from infectious diseases. However, children routine vaccination rate of Korea was 68.2% and it was not higher than expected. Korean government revised the School Health Law for every primary school children to submit the vaccination certificate record from 2005. It is quite important national infectious disease prevention policy to keep the immunizations rate high and monitor the immunizations rate continuously. To do this, National Institute of Health introduced the National Immunization Registry(NIR) Program at 2000. Objective: The aims of this study was to evaluate the Immunization Registry program which has been implementing since 2000 at the Public Health Centers(PHC). Methods: The mail survey was done from November 2001 to January 2002. 169 (69%) Public Health Centers among 244 PHC were responded. Results: The respondents of PHC said the Immunization Registry(IR) program had reduced the workload (18.5%). 69.2% said they inputted the immunization data into the IR program after the shots were given. 86.5% said they hadn`t checked or retrieved the children lists who had missed the scheduled immunization. Only 17.2% said the speed of internet for the IR program was good. It showed that 20% of respondents hadn`t written down documents, records on immunization any more. Even there were a lot of negative results, the respondents of PHC thought that the IR program was effective. They especially agreed that the IR program could make the job accurate (81.5%), convenient (71.3%), and reduced the chances of making mistakes (71.3%), increase the service quality (78.5%). And they were well adapting the job process of the IR (79.63%). Bivariate analysis showed that the software program was the important determinants of IR success. The only Bit Computer software program has been evaluated to be less satisfactory than the Integrated (Posdata operating system + Bit software) program. Other variables, such as age, duration of present job, and location of PHC (metropolitan, small city, rural area) were not significantly related. Conclusion: It seemed that the success of NIR might depend on the software program. Because Integrated program, which has been developed from 1994, include not only the general operating and management program for PHC but also IR program. It was natural to prefer Integrated program to Bit software program. So we can suggest that it is essential for the NIR to be successful that not only the immunization software program but also hardware equipments and public health information system should be further improved.

실제로 사용되는 주소의 분석을 통해 한글주소의 해석방법을 제안하고, 제안한 주소해석 방법을 이용한 주소 검색시스템의 구현에 대하여 서술한다. 주소 상위 및 하위영역의 일치검증을 각각 순차적으로 수행하는 2단계 과정을 통해 최종 배달점에 대한 순로코드를 발생한다. 우편 번호와 주소 상위영역 일치검증 단계에서는 우편버호를 이용하여 주소사전에서 검색된 주소단어와 인식된 문자 후보들과의 비교를 통해 우편 번호를 검증하게 되며, 주소 상위영역과 주소 하위영역이 분리된다. 주소 상위영역 일치검증 과정의 성능향상을 위해 혼동행렬을 제안하고, 주소 인식결과에 혼동행렬을 적용하여 검증 성공률의 향상을 통해 혼동행렬의 유용성을 확인하였다. 주소 하위영역 검증은 번지정보와 건물명 정보를 이용하여 순로코드를 발생하였다. 부분적으로 완성된 광주와 부산지역의 DPF(Delivery Point File)와 레이블링된 데이터를 이용해 분석 가능한 주소에 대해 높은 정확도를 가지고 순로코드를 발생함을 확인할 수 있었다. A systematic approach for interpreting Korean addresses based on postal code is presented in this paper. The implementation is focused on producing the final delivery point code from various types of address recognized. There are two stages in the address interpretation : 1) agreement verification between the recognized postal code and upper part of the address and 2) analysis of lower part of the address. In the agreement verification procedure, the recognized postal code is used as the key to the address dictionary and each of the retrieved addresses is compared with the words in the recognized address. As the result, the boundary between the upper part and the lower part is located. The confusion matrix, which is introduced to correct possible mis-recognized characters, is applied to improve the performance of the process. In the procedure for interpreting the lower part address, a delivery code is assigned using the house number and/or the building name. Several rules for the interpretation have been developed based on the real addresses collected. Experiments have been performed to evaluate the proposed approach using addresses collected from Kwangju and Pusan areas.

이산화탄소(CO2) 포집 및 지중저장을 위한 CO2 수송선용 저장탱크는 액체 CO2와 직접적으로 접촉할 경우 발생할수 있는 물리적/열적 탱크 손상을 방지하기 위해 화물 선적 단계 이전에 예냉과정을 거쳐야 한다. 본 연구에서는 예냉을 위해 주입되는 저온 CO2 기체의 탱크 유입량을 계산하기 위해 CO2 저장탱크 예냉과정의 수학적 모델 식을 제안하였다. 또한 비례-적분(proportional-integral: PI) 제어를 통해 공정을 제어하는 동적 모사 결과를 제시하였다. 이 때 제어 변수를 탱크 내 온도 또는 압력으로 선정한 두 가지 사례를 모사하였으며 그러한 결정이 CO2 저장탱크의 예냉과정에 미치는 영향을 해석하였다. 결과적으로 예냉과정의 PI제어에는 탱크 내 온도를 제어하는 것보다 압력을 제어하는 우회적인 방식을 택할 때 수학적 모델의 비선형성과 특이점 발생으로 인한 불안정성을 피할 수 있으므로 더 안정된 결과가 도출됨을 보였다. Storage tanks of Carbon dioxide (CO2) carriers utilized for the purpose of carbon capture and storage(CCS) into subsea strata have to undergo a pre-cooling session before beginning to load cryogenic liquid cargos inorder to prevent physical and thermal deterioration of tanks which may result from cryogenic CO2 contacting tankwalls directly. In this study we propose dynamic model to calculate the tank inflow of CO2 gas injected for precoolingprocess and its dynamic simulation results under proportional-integral control algorithm. We selected two cases inwhich each of them had one controlled variable (CV) as either the tank pressure or the tank temperature and discussedthe results of that decision-making on the pre-cooling process. As a result we demonstrated that the controllinginstability arising from nonlinearity and singularity of the mathematical model could be avoided by choosingtank pressure as CV instead of tank temperature.

Objectives: This study aimed to establish a linkage model involving regional responsible medical institutions after analyzing the existing conditions and deriving problems through qualitative analysis within the community care system. Methods: A total of 14 participants of this study were selected through the snowball sampling method, including 7 community care service providers and 7 service users. As for the research data, primary data were collected through interviews, and as a result of analyzing according to Aday&Anderson’ model, a total of 5 catergories, 8 topics, and 22 sub theme were derived. Results: The problem derived from the interview is that division services are provided for each institution due to the absence of a key central institution of community care system, and users’ commercial institutions is unclear. The second is the inconsistency between the needs and supply for community care, resulting in a possibility of delay in returning to the community after discharge. Based on these problems, it is necessary to unify it as an community care window of the Dong-community center. In addition, there is a need for public health centers to play an active role, and to establish a public-private joint system with the Health and Living Support Center to establish a model that can play a certain role. Conclusions: Therefore, based on the results of this study, it can be used as basic data when constructing community care model and applying it as an expanded model in the future.

노인인구의 의료수요에 따른 필요의료인구의 추계

문옥륜(Ok Ryun Moon),조유향(Yoo Hyang Cho),이석구(Seok Goo Lee) 한국노년학회 1991 한국노년학 Vol.11 No.1

Korea has experienced a rather rapid population aging process. The number of the elderly has increased from 1 million in 1970 to 2 million in 1990. however, the elderly will number as many as 3 million in 2000, and 5.8 million in 2020. Thus, it will take only 25 years for the number of the elderly to reach 14% of the total population from 7% in 2005. Yet, no information is available for health manpower requirement for the care of the elderly in Korea. The objective of this study is to analyze health manpower needs with respect to the care of elderlies. This paper is specifically addressed to the projection of physicians and nurses requirement by the year 2010. Ⅱ. METHODS Korea has achieved its universal health insurance program in July 1999. A population component method was applied to this analysis by breaking down its population into the following four categories : those members under the employees' health insurance, public officials and private school teachers' health insurance, regional self-employed health insurance and those under the medical assiance program. Based upon the existing data on the utilization rate and the number of days per in -and out-patient case, this study has made estimates of the daily number of elderlies-patients that will use medical care facilities of all kinds for the coming years up to 2010. Aprojection has been made on the health manpower requirement by using the optimum physician productivity per day and other criteria defined legally and customarily. Ⅲ. RESULTS In general, the medical care utilization rate for elderlies has increased much faster than is that for general population. This is particularly the case for inpatient. Average length of hospital stay for the aged is longer than that for the total population by 2.5 days per case. However, the difference is not remarkable for outpatient visits. The daily number of elderlies who will use medical facilities is estimated at 346,640 in the year 2010. This is equivalent to 8.1% of the aged at 65 and over. In other words, 51.335 beds will be occupied and 295,305 physician visits will be made nearly everyday by elderlies. Three indicators for measuring physician productivity and two indicators for nurses requirement are chosen for the purpose of projection of this study. The proportion of physicians caring for elderlies will increase from 8.7% in 1992 to 21.3% in 2010, or from 8.1% to 17.2% the same period. This difference mainly originates from variations on the medical care utilization rates of the regional self-employed health insurance program which extended to the entire target population only two years ago. Similar findings are noted for nurses. According to the projection, the proportion of nurses caring for elderlies will be doubled during the same period. Despite the fact that the current population structure is relatively young, this study shows that the Repulic of Korea will undergo a rapid change of aging in early 2000s. As a Preparatory measure, this study tries to project health manpower requirement for the coming 20 years.
