Blood-Letting Therapy is a rational and ecological medical treatment by which we can heal most of the diseases by removing the static blood which precipitates in the blood vessel and blocks the flowing of blood. And the static blood is the generic term for the injurious, bad, dead and precipitated blood which is blocked the capillary vessel. The Yellow Emperor's Canon of Internal Medicine says that "the patient is treated with drugs internally and stone acupuncture externally. "In the old texts, the blood-letting therapy is mentioned as blood-letting, network vessel pricking, bloodletting, pricking, and arousing pulses etc and it is noted down as the method of network vessel pricking in 'On the Application of Needles' of Spiritual Pivot. Nine-pricking therapy, twelve-pricking therapy and five-pricking therapy are recorded in the methods of network vessel pricking and among them, the method of squeezing blood after pricking the affected part is explained as the network vessel pricking. There are four methods of network vessel pricking, pricking, picking, cluster needling and scatter-pricking and they are fluidly applied to the various symptoms of diseases. In 'On Discriminative Treating for Patients of Different Regions' in Elementary Questions, Ki-baek emphasizes "most of the local people, there are black in skin and loose in striate, and their diseases are mostly of carbuncle kind. It is suitable to treat the disease with stone therapy to prick with stone, so the stone therapy is transmitted from the east. "And in 'On the Corresponding Relation Between the Eum and Yang of Man and All Things' in Elementary Questions, when the Emperor asked Ki-Back, he answered "sthenia means the sthenia of evil, and deficiency means the deficiency of healthy energy. When the blood is sthenic, the evil should be discharged by pricking when out letting the blood; deficiency of vital energy is the asthenia of channels and network vessels, so the energy should drain from the channel which is not deficient, to replenish. "And in this case we can use the methods of 'Breaking out the static bloods', 'driving out the static bloods', blood-letting'. With this we can infer that the blood-letting therapy is made use of the important medical treatments from the ancient times. Especially in referring to the principles of treatment in The Yellow Emperor's Canon of Internal Medicine, it mostly alluded to acupuncture therapies and only eleven times to medicinal treatments. This is to verify that the blood-letting therapy formed the foundation of the medical art. In Dong's Therapy of Acupuncture-Moxibustion and Bloodletting, Dong Kyeong-Chang gave emphasis on the points that there must be extravasated bloods without exception in the serious illnesses which is old, unnatural, accompanying acute pains and so we can revive our body‘s sprit by circulating 'gi' and static blood piled up in the network vessel, regulating the weakness and strength, and controling the disharmony of the internal organs. The blood-letting therapy has effect on the orifice in emergency, such as fore draining, freeing network vessels, harmonizing gi and blood, relieving pain, dispersing swelling and concretion, sedation, resolving toxin as well as strengthening the heart, relieving itching. So it has distinguished effect on all kinds of medical treatment to the modern people. But by the change of social customs and the confucianism of confucius - it is widely spread on the period of North and South Dynasties, 'Wi' and 'Jin' in china and the period of the Three States in korea - The blood-letting therapy which was regarded as the most important medicinal treatment withered rapidly. And Confucius accentuated the importance of our body and all its members, loyalty and filial piety and banned any damage of our body under no circumstances. As a result of it, the therapy of blood-letting had a rapid decrease and barely kept itself in existence in both countries. What is worse, at the period of Japanese colonial rule of korea and our nation's founding of early stage, it has been withered by the high-handed policy to change Oriental Medicine into modern medical science. So the therapy of blood-letting barely kept itself in existence in some Buddhist temples. Another case, it has handed down as a old-fashioned quick fix in folk remedies. But all kinds of the contamination of heavy metals and the misuses of antibiotics are widely spread nowadays, which increased diseases of adult people and incurable diseases as modern society unavoidably made its way into a highly industrial society. To make us more miserable, the western medical science - the antibiotics and surgical operation medical science - already reveals itself into a limit. The necessity of a new medical science which can give a security to the patients who are suffering from the diseases of adult people and the incurable diseases is especially come into the force nowadays. In view of the results after bibliographically studying on the blood-letting Therapy in Elementary Questions of the Yellow Emperor's Canon of Internal Medicine, the blood-letting therapy has acted for the important Oriental medicinal science and has been clarified the prominent effects on the diseases of adult people and the incurable diseases. So it is regarded as an appropriate thing that we lay out a determined theory of the blood-letting therapy and of course prevent the unwanted side effects from inappropriate medicinal treatments, and make full use of clinic by elevating the curative value and that we win back our self-respect of medical treatment which is dominated from the western medical science and ultimately contribute to national medical welfare.

경제 및 산업의 원천 에너지원인 전력은 생산과 소비의 지역적 상이함으로 장거리 수송을 필수로 하며, 다중환상망(Multi-loop) 형식의 송배전계통으로 전력을 공급한다. 실질적 사용에 앞서, 변전소내 변압기를 통해 변전과정을 거쳐 각 사용처의 특성을 고려하여 전력공급이 이루어지고 있으며 변압기는 본체, 권선, 절연유, 부싱등의 구조로 결합되어 있다. 변전소에서 발생하는 변압기화재는 가구와 상업시설등에 전기공급을 중단시키고 각종 안전사고를 발생시키는 1차 손실뿐만 아니라 2차적으로 경제 손실을 야기한다. 화재의 원인은 부싱 하부파손에 따른 절연유 유출과 약 1초 이내 발화점에 도달하는 절연유에 의한 화재의 연쇄반응으로 파악된다. 화재피해의 최소화를 위해 연기감지기, 자동소화설비 등이 구축되어있으나 감지기의 동작 및 소화가스 방출지연 등으로 화재진화를 위한 골든타임 확보의 부재가 문제되고 있다. 이에 본 연구는 초기 화재진화에 따른 골든타임 확보의 중요성에 따라 화재확산을 방지하고 절연유 누출을 차단하는 능동적 메커니즘의 필요에 따라 수행되었다. 따라서 화염에 의해 팽창하는 고온형상 유지물질과 기계적 화염차단장치를 적용한 부싱방화구조체를 개발하였다. 실제 부싱 및 프렌지규격을 적용하여 제작된 변압기모형에 부싱방화구조체를 설치하여 실규모 화재실험을 수행하였다. 초기화염으로부터 3초내에 정확한 위치와 높이에 부싱방화구조체가 작동함을 확인하였으며 이는 실제 변압기화재 시 화염 확대를 효과적으로 차단할 수 있을 것으로 사료된다.

The anticommunist guerrillas' activities that aretheconcern of this article took place largely in North Korea or behind the enemy-held lines. Verifying their history is accordingly difficult and requires careful attention, but despite their active operations the military as well as the scholarly community have been lax in studying them. The Korean War came to be perceived as a traditional, limited war with regular battles, so that the studies addressed mostly the regular operations, and guerrilla warfare is remembered as an almost 'exclusive property' of the communist invaders; a small wonder that the anticommunist guerrillas have not been studied much and the collection of materials neglected. Therefore, in contrast with the witness accounts concerning regular battles, witness resources were of a small volume about these "patriots without the service numbers." For the above reasons the guerrilla participants and their later-organized fellowships took to the task of leaving records and compiling the histories of their units. They became active preservers of history in order to inform later generations of their works and also to secure deserved benefits from the government, in a world where none recognized their achievements. For instance, 4th Donkey Unit published witness accounts in addition to a unit history, and left video-recordings of guerrilla witnesses before any institute systematized the oral history of the guerrillas. In the case of Kyulsa ("Resolved to Die") Guerrilla Unit, the unit history was 10 times revised and expanded upon for publication, contributing substantially to the recovery of anticommunist guerrilla history which had almost totally lacked documented resources. Now because the guerrilla-related witness accounts were produced through fellowship societies and not individually, it often took the form of 'collective memory.' As a result, though thousands of former guerrillas remain surviving, the scarcity of numerous versions of, or perspectives upon, an event renders difficult an objective approach to the historical truth. Even requests to verify the service of a guerrilla member or to apply for decoration or government benefits for those killed in action, the process is taken care of not at the hands of the first party but the veteran society, so that a variety of opinions are not available for consideration. Moreover, some accounts were taken by American military personnel, and since some historians, unaware of official documents or evaluation of achievements, tended to center the records around their own units and especially to exaggerate the units' performances, they often featured factual errors. Thefollowing is the means to utilize positively the aforementioned type of witness accounts in military history research. It involves the active use of military historical detachments (MHD). As in the examples of those dispatched by the American forces during the Korean War, experts should be dispatched during, and not just after, wartimes. By considering and investigating the differences among various perspectives on the same historical event, even without extra documented resources it is possibleto arrive at theerrors or questionable points of the oral accounts, supplementing the additional accounts. Therefore any time lapses between witness accounts must be kept in consideration. Moreover when the oral accounts come from a group such as participants in the same guerrilla unit or operation, a standardized list of items ought to be put to use. Education in oral history is necessary not just for the training of experts. In America wherethefield sees much activity, it is used not only in college or graduate programs but also in elementary and lifetime educational processes. In comparison in our nation, and especially in historical disciplines, methodological insistence upon documented evidences prevails in the main, and in the fields of nationalist movement or modern history, oral accounts do not receive adequate attention. Like ancient documents and monuments, oral history also needs to be made a regular part of diverse resource materials at our academic institutes for history. Courses in memory and history, such as those in American colleges, are available possibilities.

업무 과정에서 생산되는 모든 기록들은 대부분 종이 형태로 작성, 관리해 왔다. 그러나 최근에는 전자적 형태의 기록이 종이를 대신하는 추세이다. 전자기록은 종이기록과 달리 생산과 보관의 편리성을 갖고 있어서 업무 효율성 극대화에 기여한다. 그러나 종이기록처럼 원본과 사본의 뚜렷한 구분이 어렵고 전자적 환경에서 외부 영향에 의해 변경, 훼손될 수 있으며 S/W, H/W 환경이 변화할 때 마다 즉각적인 조치를 취함에 있어 어느 경우에는 막대한 인력과 비용이 발생하기도 한다. 그럼에도 불구하고 업무의 편리성과 생산비용의 효율성으로 인해서 현재 업무 환경에서 전자기록 생산이 차지하는 비중은 날로 높아지고 있다. 이에 정부와 민간, 학계에서는 전자적 형태의 기록이 가지고 있는 장점을 극대화하면서 위험을 최소화할 수 있는 방안 마련에 노력하고 있다. 그 방법 중의 하나가 본 글에서 소개하고 있는 공인전자문서 보관소 사업(이하 공전소 사업)이다. 원활한 공전소 사업를 위해서 행정적으로는 전자기록의 법적 효력 보장과 기술적으로는 전자기록의 신뢰성, 진본성 보장을 우선적으로 확보해야 했다. 그래서 공전소 사업 주체인 산업자원부와 한국전자거래진흥원은 2005년 전자거래법 개정을 통해서 전자기록의 법적 효력 보장 규정을 보완하고 2006년에는 공전소 이용자의 요구인 전자기록의 장기보존과 신뢰성 확보를 위한 연구가 진행됐다. 이러한 공전소의 목적 달성을 위해 공전소 전자문서 정보패키지 연구에서는 디지털 형태의 장기보존을 위한 표준인 ISO 14721 정보패키지 모델을 적용하여, 전자기록이 생산 시점의 SIP, 보관 시점의 AIP, 이용자 활용 시점의 DIP 메타데이터 기능을 마련하고 이들이 공전소 정책에 따라 구현될 수 있도록 정보패키지를 생성, 관리하는 프로세스를 제시하고 있다. 이에 본 글에서는 그동안 진행되었던 연구 내용을 바탕으로 공전소 전자문서 정보패키지의 생성, 진행 과정과 적용 방법, 패키지 간의 흐름도를 소개하고 이를 바탕으로 기록관리 영역에서 지속적으로 연구해야 할 이슈에 대해 제시하고자 한다.

본 연구는 일반인에게 안전한 실내공기질 개선수단으로 인식되는 공기정화식물의 효율적 적용을 위해 실내공조에 요구되는 총풍량 확보가 가능한 식생기반 바이오필터 시스템을 제안하고자 했다. 시스템의 정량적 성능평가는 강의실형태의 실험실 체적 $332.73m^3$ 내 16명의 재실자 조건에서 목업단위 시스템의 공조 성능, 실내공기질 및 쾌적지표 개선효과에 대한 시계열 분석으로 진행되었다. 우선, 시스템 구동을 통해 총 $1,411.22m^3/h$의 유출 총풍량을 확보하여, 4.24 ACH의 환기율을 제공할 수 있었다. 실내온도는 $1.6^{\circ}C$, 흑구온도는 $1.0^{\circ}C$ 감소가 확인되었으며, 상대습도는 24.4% 상승한 최대 82.0%까지 증가하였다. 상대습도 급증에 따른 쾌적도 감소현상은 송풍기 구동에 따라 발생되는 실내기류로 상쇄되는 것으로 판단된다. 또한, 시스템 가동에 따른 공기질 개선지표 중 $PM_{10}$은 39.5% 감소한 평균 $22.11{\mu}g/m^3$을 기록하였다. 반면, $CO_2$는 최대 1,329 ppm까지 지속적으로 농도가 상승했는데, 이는 광도조건이 광보상점을 만족하지 못해 적용 식물과 재실자에서 방출되는 $CO_2$가 처리되지 못한 것으로 해석된다. 실내쾌적지표의 경우 PMV는 평균 83.6 % 감소된 -0.082, PPD는 평균 47.0% 감소된 5.41%에 수렴하여 식생기반 바이오필터 구동에 의해 높은 쾌적범위의 실내공간조성이 가능한 것으로 판단되었다. 본 연구의 한계는 소수 참여인원과 단기간 실험으로 인하여 시스템의 성능 규명이 제한적인 부분이었으며, 보다 장기간의 실험을 통해 바이오필터에 도입된 식생의 생육상태에 따른 압력손실 변화, 미세먼지 저감에 대한 구체적인 메커니즘 규명 등의 후속연구가 진행되어야 할 것이다.
