사회의 격변화로 모든 정보는 신속하고 정확한 것을 요구하게 되었고, 상수도 등 국토기반시설은 그 복잡성과 급격한 변화에 따라 2차원적인 정보관리의 한계를 맞게 되었다. 현재 대부분의 수치지도 제작 자료는 tablet을 가지고 수동적인 디지타이징에 의해 얻어지고 있다. 최근 고가의 스캐너가 대중화되고 스캐닝의 전·후 처리의 소프트웨어가 개발되어 앞으로 그 활용이 기대되고 있다. 본 연구에서는 tablet으로 디지타이징 한 것보다 스캐닝의 방법이 수치지도 제작을 위해 편리하고 또한 백터화된 도면의 3차원 모델링에 대한 가능성을 제시하였다. 상수도 사업에 있어서는 계획 및 수행에 필요한 신속·정확한 정보의 제공으로 효율적인 도면관리, 업무의 능률화 및 고도화를 기하였다. 또한 시민의 요구에 대한 서비스의 향상과 여타 시스템과의 연계를 통해 종합정보시스템으로 가능성을 제시하였다.

Korea's social health insurance system was introduced in 1977, which has made a universal coverage possibly by July 1989. Korean government had pursued a single objective for the last decade to put the whole population under the coverage of medical security, and the objective was achieved within 12 years. The rapid accomplishment is primarily due to such factors as limited benefits, high copayment rate, low contributions as well as rapid economic growth. There are several sources of pressure for the implementation of social health insurance such as health professional group, labor unions, politicians, international organizations etc.. However it is important to look at the feasibility of social health insurance. Among other things, it is necessary to identify the administrative infrastructure of insurance system and to assess income for source of fund. As many developed countries, Korea began to apply health insurance to the employees of the large firms, and the expansion based on employment status. Thus the several funds system was inevitable according to the gradual expansion strategy. However many persons had criticized several funds system in respect with equity and efficiency aspects. In the short history of the Korean health insurance, whether one fund or sever or funds had been the most controversial issue. In Febrary 1999, the National Assembly passed the act of one fund system. From July 2000 separate funds will be unifed under new health insurance scheme. In this study we will analyze the policy making process on implementation, expansion and integration of health insurance system of Korea. And also analyse problems related to policy making.

Occipital neuralgia is usually defined as paroxysmal stabbing pain in the greater or lesser occipital nerve (GON or LON) distribution. In occipital neuralgia patients, surgical considerations are carefully taken into account if medical management is ineffective. However, identification of the occipital artery by palpation in patients with thick necks or small occipital arteries can be technically difficult. Therefore, we established a new technique using transcranial Doppler (TCD) sonography for more accurate and rapid identification. The patient was a 64-year-old man who had undergone C1-C3 screw fixation and presented with intractable stabbing pain in the bilateral GON and LON distributions. In cases in which pain management was performed using medication, physical therapy, nerve block, or radiofrequency thermocoagulation, substantial pain relief was not consistently achieved, and recurrence of pain was reported. Therefore, we performed occipital neurectomy of the bilateral GON and LON by using TCD sonography, which helped detect the greater occipital artery easily. After the operation, the patient’s headache disappeared gradually, although he had discontinued all medication except antidepressants. We believe that this new technique of occipital neurectomy via a small skin incision performed using TCD sonography is easy and reliable, has a short operative time, and provides rapid pain relief.

Ever since the foundation of the Korean Society for Preventive Medicine in 1947, members of the Society had made remarkable contributions to the public health development and national health promotion. They had played key roles in establishing national health system, improving environmental hygiene, controlling infectious and chronic diseases, promoting family planning, improving industrial and environmental health, and developing health service management. However, the Society had less actively responded to the changes in health service needs of the population that were caused by a rapid epidemiologic transition in last a few decades. Early detection and treatment of chronic diseases including cancer and cardiovascular diseases and risk reduction by the life style modification are major approaches to the contemporary national health problems and they are the core contents of preventive medicine. The author proposed to develop the clinical preventive medicine specialist who will have additional training in clinical medicine for health screening and life style modification to the current preventive medicine training program and thus will be able to provide comprehensive preventive medical services. Another area that the Society may take the initiative is training preventive medicine specialist in the disaster, including bioterrorism, preparedness and management. The Society should be more active in proposing health policy and health service program and also participate collectively in a large scale health research project of the government. These approaches may not only contribute more effectively to the national health promotion but also improve the identity of the Society.

The study evaluated the accuracy and intra-rater reliability for OWAS (Ovako Working posture Analysing System), RULA (Rapid Upper Limb Assessment), REBA (Rapid Entire Body Assessment) to improve their evaluation accuracy and reliability. Participants (n = 163) with undergraduate degree were recruited in this study and trained for 6 hours about the ergonomic assessment methods. Ergonomic assessments were conducted using OWAS, RULA, and REBA for a representative work with dynamic posture found in manufacturing industries. The study compared action categories (overall level) and detailed evaluation scores for individual body part. Action categories of the participants significantly differed from the golden reference defined by ergonomic experts. The participants underrated or omitted scores for truck (37.4% of the participants) and legs (52.8%) in OWAS. Similarly, the participants underrated or omitted additional scores for all body parts except the hand and wrist in RULA (53.5%) and REBA (54.8%). On the other hand, the participants overrated scores for the hand and wrist in RULA (55.2%) and REBA (39.9%). The results found in this study can help of selecting focus points and parts during assessment and education to improve accuracy and reliability of the ergonomic assessment methods.

It is necessary to respond to rapid technological changes such as the 4th industrial revolution and digital transformation across industries. And, a change in the university education system is necessary in a crisis situation of universities due to the rapid decrease of the school-age population. This study is aimed at practical competency with the ability to apply intelligent information technology to their job fields based on a basic understanding of intelligent information technology rather than advanced competency centered on theory and research. Instead of presenting the curriculum system diagram so that it can be flexibly applied to the design and development of the curriculum for intelligent information technology, training modules according to job and level were presented. In relation to intelligent information technology, a questionnaire was conducted for college professors, and industry experts were conducted on the derived educational modules to reflect the opinions of the industry. Industry experts said that collaboration with PBL, Capstone, and industry is necessary to improve problem-solving and communication skills.

As the living standards have been enhanced thanks to rapid to rapid economic growth following industrial progress, today the advancement of woman into specialized jobs keep expanding not only for economic purpose such as increasing family income but also due to changed perception on woman's role, i.e. self-realization. In the actual situations, however, women are generally placed in a inferior position compared with men in most jobs, despite existence of gender equality policy. Therefore, concern and study on female adaptation into job and their work attitude have become increasingly important, which can contribute to alleviating women's discontent in the work but to raising efficiency of job execution and improving work quality. In this treatise, I researched the job attitude of woman for the period of 1980 up to 2005, with interval of every 5 years. For empirical analysis, research has been done towards females teachers in elementary and middle schools as well as female works in financial institutions. Both job fields have comparatively high percentage of female employees and have less sexual discrimination. The purpose of this vertical research is (1) to find out how women workers perceive their job environment, (2) to analyze empirically the change in female job attitude and their flow of consciousness. Ultimately this treatise aimed at contributing to efficient management of female work force in our society.

Microcystis sp. is one of the most common harmful cyanobacteria that release toxic substances. Counting algal cells is often used for effective control of harmful algal blooms. However, Microcystis sp. is commonly observed as a colony, so counting individual cells is challenging, as it requires significant time and labor. It is urgent to develop an accurate, simple, and rapid method for counting algal cells for regulatory purposes, estimating the status of blooms, and practicing proper management of water resources. The flow cytometer and microscope (FlowCAM), which is a dynamic imaging particle analyzer, can provide a promising alternative for rapid and simple cell counting. However, there is no accurate method for counting individual cells within a Microcystis colony. Furthermore, cell counting based on two-dimensional images may yield inaccurate results and underestimate the number of algal cells in a colony. In this study, a three-dimensional cell counting approach using a novel model algorithm was developed for counting individual cells in a Microcystis colony using a FlowCAM. The developed model algorithm showed satisfactory performance for Microcystis sp. cell counting in water samples collected from two rivers, and can be used for algal management in fresh water systems.

This study aims to compare six observational methods for assessing arm- and hand-intensive tasks, based on literature review. The comparison was conducted in viewpoints of body regions, force/external load, motion repetition, other factors including static posture, coupling, duration/break, pace, temperature, precision task, and final risk or exposure level. The number of risk factors assessed was more, and assessment procedure was more complex than the observational methods for assessing whole-body postural loads such as Ovako Working Posture Analysis System(OWAS), Rapid Upper Limb Assessment(RULA), and Rapid Entire Body Assessment(REBA). Due to these, the intra- and inter-reliabilities were not high. A past study showed that while Hand Arm Risk Assessment Method(HARM) identified the smallest proportion of the work tasks as high risk, Strain Index(SI) and Quick Exposure Check(QEC) hand/wrist were the most rigorous with classifying most work tasks as high risk. This study showed that depending on the observational technique compared, the evaluation factors, risk or exposure level, and evaluation results were different, making it necessary to select a technique appropriate for the characteristics of the work being assessed.
