최근 정부는 SOC디지털화 계획의 하나로 스마트 물관리 및 홍수 예방을 위해 배수시설 자동·원격제어체계를 국가하천 57%에 도입(1,800억원)하고 실시간 모니터링체계(300억원)를 구축하며, 댐 11개소에 빅데이터를 기반으로 한 스마트 댐 안전관리 체계(150억원)를 마련할 계획입니다. 이러한 스마트 물관리 및 홍수 예방을 위해서는 하천의 실시간 유속 측정을 통해 중간단면법을 적용하여 유량을 정확히 계산할 수 있는 시스템의 연구가 필요합니다. 이러한 시스템의 구현과 정확도를 높이기 위해서 가장 중요한 것은 실시간 유속 측정의 정확도를 확보하는 것입니다. 현재 실시간 유속 측정을 위해 미국, 유럽 등의 전자파 표면 유속 측정용 레이다 센서를 도입하여 시스템에 적용하고 있으나 고가의 가격, 유속 측정 범위의 한계 및 기술 지원 미흡 등의 문제로 인해 시스템의 개선 요구가 지속되고 있는 상황입니다. 따라서 실시간 유속 측정을 위한 전자파 표면 유속 측정용 레이다 센서를 자체 개발하여 개선된 유량 측정 및 홍수 예측 시스템을 제시하고자 합니다.

본 연구는 동진강 유역의 수질 보전을 위한 기초자료를 얻기 위하여 동진강 본류와 이에 유입되는 정읍천을 대상으로 2001년 5월부터 11월까지 수질 모니터링을 실시하였다. 동진강 본류의 수질은 BOD기준으로 상수원 II$\sim$IV등급(2.84$\sim$6.45 mg/L)으로 지점별로는 DJ6(정읍천 합류후)이 4.07 mg/L로 높게 나타나 III급수의 수질을 유지하였다. COD는 지점별로 11.20$\sim$32.96 mg/L의 범위로 정읍천 합류후의 농도가 32.96 mg/L로 가장 높게 나타나 정읍천을 통한 본류의 오염물질량의 증가를 알 수 있었다. T-N의 경우 4.16$\sim$5.84 mg/L의 범위로 유역 전반에 걸쳐 오염이 이루어지고 있는 것으로 나타났고, T-P의 경우 BOD, COD와 마찬가지로 정읍천 합류후가 0.19 mg/L로 타 지점에 비하여 높게 조사되었다. 본류의 COD의 경우 장마후 갈수기에 높은 농도를 나타냈고, T-P의 경우는 하천의 유량이 증가하는 홍수기보다 장마전 갈수기의 오염정도가 높고 이후 장마후 갈수기로 갈수록 수질이 악화되는 것으로 조사되었다. 동진강 수질의 오염은 주로 하류로 갈수록 그 정도가 심하게 나타나는데, 이것은 정읍천을 통해 유입되는 도시생활하수와 인근 공장단지의 산업폐수가 그 주 요인으로 오염물질(BOD, COD T-N 및 T-P)의 농도가 상승하는 주원인이 되고 있다. 따라서, 동진강 수계의 수질관리를 위해 주 오염원이 되고 있는 정읍천의 도시생활하수와 공장단지에서 방류되는 산업폐수의 제어에 대한 대책이 먼저 이루어져야 할 것으로 판단된다.

The purpose of this study was to serve as a basis for school health care of better quality, by making a comparative analysis of the health care satisfaction and attitude of elementary school students in consideration of their general characteristics and the presence or absence of nurse teacher. The subjects in this study were 919 selected six graders in 16 elementary schools in the city of Tongduchun, Koyang and Euijungbu, Yangju-kun and Yeunchun-kun. A survey was conducted with questionnaire designed for measurement of health care satisfaction and attitude. As a result of analyzing the data collected from June 1 through 15, 2000, the conclusions were as follows. 1) As for the general characteristics of the students investigated, the subjects included 513 boys(55.8%) and 406 girls(44.2%). The schools where 390(42.4%) students attended were located in municipal area, and the schools where 529(57.6%) students attended were located in kun area. 608(66.2%) students had a nurse teacher at their schools, while 311(33.8%) students had no nurse teacher. 498(54.2%) had an experience to use the health room this year, but 421(45.8%) had no such an experience. Their mean school life satisfaction was scored $3.42{\pm}.71$, above the average. And their health condition was rated $3.81{\pm}.87$, which implied they tended to be in good health. 2) The mean satisfaction at the health room operation was scored $3.33{\pm}.71$, above the medium level. What they were most satisfied with($4.02{\pm}1.08$) was, among the health room facilities, that there were beds. But they expressed the least satisfaction($2.83{\pm}1.17$) at the location of health room. The presence or absence of nurse teacher made a significant difference to their satisfactionat health room operation, because the students in schools with nurse teacher showed greater satisfaction($3.42{\pm}.72$) than the others in schools with no nurse teacher did($3.15{\pm}.66$). 3) Concerning their attitude to use the health room in case of disease or accident occurrence, a lot of students in schools with a nurse teacher, who had ever suffered from indigestion, headache or traumatic injury, used the health room. In schools with no nurse teacher, there was a tendency to talk to their class teachers(p<.001). The recognition of the necessity for health counseling was generally on a medium level. The counselor whom they wanted to discuss health problem with was family or friend in the largest cases. Few students discussed with class teachers in case there was a nurse teacher in school. Instead, some of them discussed with friend, family or nurse teacher, and there was a significant difference between them(p<.001). 4) The mean satisfaction at health, sanitation and environmental management was rated $3.20{\pm}.90$, above the average. The classroom lighting gave them the best satisfaction with $3.67{\pm}1.07$, but the satisfaction at toilet cleanness and disinfection was not good with $2.83{\pm}1.19$. By the presence or absence of nurse teacher, those who had a nurse teacher expressed better satisfaction at water supply facilities including hot water than the others who had no nurse teacher did(p<.001). But no significant difference was observed in the other items. 5) The health education satisfaction was rated $3.19{\pm}.99$, which was on a medium level. By item, the mean satisfaction level was $3.36{\pm}1.19$ at nurse teacher's explanation about treatment, $3.13{\pm}1.15$ at the frequency of health education, and $3.08{\pm}1.16$ at the explanation on the cause of disease. By the presence or absence of nurse teacher, the students with nurse teacher showed significantly better satisfaction at every factor0(p<.001). 6) Regarding health education attitude, their recognition of the need for school health education was scored $3.89{\pm}.96$. Those who had a nurse teacher felt it more necessary($3.96{\pm}.92$), yet the others who had no nurse teacher felt its necessity a little less($3.74{\pm}1.01$). The most preferred thing for them to learn in health education was first aid, followed by sex education, obesity prevention, safety accident prevention in school and outdoors, smoking-related health, good use of leisure time, and environmental pollution cause in the order named. According to the presence or absence of nurse teacher, there was a significant difference in sex education(p<.01), but no significant disparities were found in the other factors. The most preferred person who would offer health education was a lecturer from the outside(45.8%) and nurse teacher(45.4%). Their preference for class teacher as a person in charge of health education was just 8.8%. But the presence or absence of nurse teacher didn't produce any differences to their preference for a person in charge of health education.

The practical application of modern space science and technology have resulted in many actual and potential gains of mankind. These successes have conditioned and increased the need for a viable space law regime and the challenge of space has ultimately led to the formation of an international legal regime for space. Space law is no longer a primitive law. It is a modern law. Yet, in its stages of growth, it has not reached the condition of perfection. Therefore, under the existing state of thing, we could carefully say that the space law is one of the most newest fields of jurisprudence despite the fact that no one has so far defined it perfectly. However, if space law can be a true jurisprudential entity, it must be definable. In defining the space law, first of all, the grasp of it's nature iis inevitable. Although space law encompasses many tenets and facets of other legal discriplines, its principal nature is public international law, because space law affects and effects law relating intercourse among nations. Since early 1960s when mankind was first able to flight and stay in outer space, the necessity to control and administrate the space activities of human beings has growingly increased. The leading law-formulating agency to this purpose is the United Nation's ad hoc Committee on Peaceful Uses of Outer Space("COPUOS"). COPUOS gave direction to public international space law by establishing the 1963 Declaration of Legal Principles Governing the Activities of the States in the Exploration and Use of Outer Space("1963 Declaration"). The 1963 Declaration is very foundation of the five international multilateral treaties that were established successively after the 1963 Declaration. The five treaties are as follows: 1) The Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space including Moon and other Celestial Bodies, 1967. 2) The Agreement on the Rescue of Astronauts, the Return of Astronauts, and the Return of Objects Launched into Outer Space, 1968. 3) The Convention on International Liability for Damage Caused by Space Objects, 1972. 4) The Convention on Registration of Objects Launched into Outer Space, 1974. 5) The Agreement Governing Activities of States on the Moon and Other Celestial Bodies: Moon Treaty, 1979. The other face of space law is it's commercial aspect. Space is no longer the sole domination of governments. Many private enterprise have already moved directly or indirectly into space activities in the parts such as telecommunications and space manufacturing. Since space law as the public international law has already advanced in accordance with the developments of space science and technology, there left only a few areas untouched in this field of law. Therefore the possibility of rapid growth of space law is expected in the parts of commerical space law, as it is, at this time, in a nascent state. The resources of the space environment are also commercially both valuable and important since the resources include the tangible natural resources to be found on the moon and other celestial bodies. Other space-based resources are solar energy, geostationary and geosynchronous orbital positions, radio frequencies, area possibly suited to human habitations, all areas and materials lending themselves to scientific research and inquiry. Remote sensing, space manufacturing and space transportation services are also another potential areas in which commercial. endeavors of Mankind can be carried out. In this regard, space insurance is also one of the most important devices allowing mankind to proceed with commercial space venture. Thus, knowlege of how space insurance came into existence and what it covers is necessary to understand the legal issues peculiar to space law. As a conclusion the writer emphasized the international cooperation of all nations in space activities of mankind, because space commerce, by its nature, will give rise many legal issues of international scope and concern. Important national and world-community interests would be served over time through the acceptance of new international agreements relating to remote sencing, direct television broadcasting, the use of nuclear power sources in space, the regularization of the activities of space transportation systems. standards respecting contamination and pollution, and a practical boundary between outer space and air space. If space activity regulation does not move beyond the national level, the peaceful exploration of space for all mankind will not be realized. For the efficient regulation on private and governmental space activities, the creation of an international space agency, similar to the International Civil Aviation Organization but modified to meet the needs of space technology, will be required. But prior to creation of an international organization, it will be necessary to establish, at national level, the Office of Air and Space Bureau, which will administrate liscence liscence application process, safety review and sale of launch equipment, and will carry out launch service.

최근 들어 학교폭력문제는 학교 내에서의 구성원간의 범죄양상에서 그치지 않고 외부인의 학교 내 침입범죄로까지 비화되어 학교가 이제는 더 이상 교육만이 이루어지는 범죄로부터의 안전지대는 아니게 되었다. 특히 초등학교의 경우에는 외부 침입자에게 대항하여 이를 제압할 수 있는 사람들이 거의 없기 때문에 침입범죄에 취약한 장소이다. 서울특별시는 2011년 3월 1일부터 관내 국 공립초등학교를 대상으로 학교보안관제도를 시행하고 있다. 하지만 학교보안관 사업이 사실상 경비업법상의 경비업무를 주 내용으로 하고 있음에도 불구하고, 경비업법의 적용을 배제한 채, 서울시와 운영업자의 도급계약에 의한 사법상 계약(私法上 契約)의 한 형태로 운영하고 있어 여러 가지 문제를 야기하고 있다. 첫째, 학교보안관 관련 손해발생 시, 경비업무가 아니므로 원칙적으로는 운영사업자가 가입하고 있는 경비업자 영업배상책임보험 적용이 배제되어, 피해자의 손해보전을 위한 담보가 취약하게 된다. 둘째, 학교보안관의 임무를 계약서에 개별약정하고 있으나, 이것만으로는 부족하고, 경비업법상의 경비원의 의무 등의 관련의무 등의 일반규정 적용이 요구된다. 셋째, 학교보안관의 교육은 상대적으로 보다 체계화된 경비업법상의 교육 프로그램과 연계하도록 하고, 학교폭력예방을 위하여 특별히 필요한 관련 전문교육은 부가 편성 운영하도록 하는 것이 타당하다. 넷째, 서울시의 여론조사결과에도 불구하고, 시민들은 여전히 경찰관 등 학교주변의 순찰강화를 요구하고 있으므로, 경찰과의 적극적인 협력관계를 경비업법의 적용으로 법적 제도적으로 뒷받침할 필요가 있다. 다섯째, 경비업법의 적용으로 인한 경비지도사 제도 운영이나 경찰의 지도 감독, 그리고 각종 행정처분 등으로 학교보안관 사업의 성공을 담보해 낼 수 있다. 따라서 이 연구는 이제부터라도 경비업법을 적용하여 학교보안관 사업이 관리 운영면에서 보다 내실 있고 지속적인 확대 발전이 가능하도록 할 것을 제시하고 있다.

The purposes of this study were to offer foundation making more certain standards of musculoskeletal disorder diagnosis, We researched musculoskeletal symptoms degrees, frequencies, and cares and then examined relation between musculoskeletal symptoms and diagnosis of musculoskeletal conditions using moire topography among workers at an automobile manufacturing plant. Therefore we propose the possibility of moire topography as diagnosing utilities of musculoskeletal disorders. Methods: This study was to examine the general characteristics, complaints of musculoskeletal symptoms, and work-related musculoskeletal disorder rates of cervicobrachial and lumbar area by survey among 435 workers at an automobile manufacturing plant and then to show each frequency and percentage, In the diagnosis using moire topography, we studied pain control necessity of cervicobrachial and lumbar area, 435 subjects were classified by 5 levels: A(no symptoms), B(need management), C(need treatment) and then more divided by B1(light symptoms)/B2(heavy symptoms), C1(light symptoms)/C2(heavy symptoms), And musculoskeletal areas were divided by 2 parts, cervicobrachial area(neck, shoulder, arm&elbow, and wrist&hand) and lumbar area, Then, frequency and percentage of each musculoskeletal areas(cervicobrachial and lumbar area) were appeared. At last, Pearson's chi-square test analysis was utilized to observe the relation between diagnosis using moire topography and general characteristics and the relation between diagnosis using moire topography and work-related complaint of musculoskeletal symptoms of cervicobrachial and lumbar area, Results: The subjects employed for this research were categorized into; by gender, all of them were males(l00%): by age, under 35 years 12 %, 36-40 years 56.3%, 41-45 years 26.3 %, and above 46 years 5.3% with 36-40 years accounting for most of it. By living location, owned houses represented 69.7%, rented houses 23.4%, monthly-rented 1.6%, the others 5.3%; by education, middle school and lower represented 3.0%, high school 89.4%, and junior college and higher 7.6% with high school occupying most of the group. By marital status, married represented 95.2%, unmarried 4.1%, and the others 0.7% with most of them married; by alcohol, drinking represented 81.8% and non-drinking 18.2%; by smoking status, smoking represented 53.6%, non-smoking 46.4% with no big difference between them. By working time(hours/week), below 50 represented 26.9%, 50-60 67.6%, above 60 5.5%; by working time(hours/day), below 9 represented 21.6%, 10-12 73.1%, above 13 5.3%; by job tenure(years), below 10 represented 25.1%, 11-15 54.3%, 16-20 15.2%, above 21 5.5%. By personal income per year, below 30 million won represented 11.0%, 30-40 84.8%, above 40 4.1%; by sleeping hours, below 6 hours represented 26.7%, 7-8 hours 69.9%, above 9 hours 3.4%. Complaint rates of musculoskeletal symptoms and work-related musculoskeletal disorder rates were 63.9% and 54.9% with shoulder area occupying most of both them. By pain degree of musculoskeletal symptoms, shoulder area represented $2.73{\pm}0.84$, lumbar area $2.66{\pm}0.86$, wrist and hand area $2.59{\pm}0.86$, neck area $2.55{\pm}0.74$, and arm and elbow area $2.48{\pm}0.71$. By cares about musculoskeletal symptoms, taking medication or care represented 34.4%-46.7%, absence or leave 15.4%-28.7%, and job transfer 6.3%-11.5%. So experienced cases more than one thing among cares about musculoskeletal symptoms represented 39.6%-54%. In the diagnosis using moire topography, pain control necessity of cervicobrachial area was shown below; A(no symptoms) 20.7%, B1(need management/light symptoms) 64.6%, B2(need management/heavy symptoms) 11.5%, C1(need treatment/light symptoms) 3.0%, C2(need treatment/heavy symptoms) 0.2%. By lumbar area, A(no symptoms) 8.7%, B1(need management/light symptoms) 52.2%, B2(need management/heavy symptoms) 30.3%, C1(need treatment/light symptoms) 8.7%, C2(need treatment/heavy symptoms) was none. In the relation between pain control necessity and general characteristics, age(P=0.013), education(P=0.000), and job tenure(P=0.012) with pain control necessity showed differences with significance. The relation between pain control necessity and complaint of musculoskeletal symptoms of cervicobrachial and lumbar area showed no difference with significance; in cervicobrachial area represented P=0.708, lumbar area P=0.318 Conclusions: This study for musculoskeletal symptoms on workers at automobile manufacturing plant showed that complaint rates of musculoskeletal symptoms for cervicobrachial and lumbar area were so high, 63.9%. But Pearson's chi-square test analysis was utilized to study the relation between musculoskeletal symptoms and the diagnosis using moire topography, showed no differences with significance. They have no differences with significance, but the prevalence rates of diagnosis using moire topography for cervicobrachial and lumbar area were more higher than complaint rates of musculoskeletal symptoms; complaint rates of musculoskeletal symptoms were 52.4%, 34.5% and the diagnosis using moire topography were 79.3%, 91.3% for cervicobrachial and lumbar area. The results of this study indicate that the diagnosis using moire topography can find weak musculoskeletal disorders that an individual can not feel, not be judged work-related musculoskeletal disease. Therefore, this study has an important meaning that diagnosis using moire topography can predict and control own physical condition complete musculoskeletal disorders beforehand, since oriental medicine theory considers that prevention is important.
