연구배경: 동일한 환자를 대상으로 조혈모세포이식 전 일반 병실에서의 관해유도 항암제치료 및 강화요법으로 인한 호중구감소 기간의 감염양상과 고용량 항암제치료 후 무균실에서의 조혈모세포이식 시 호중구감소 기간의 감염양상을 중심정맥관 관련 패혈증을 중심으로 비교 연구함으로써 효율적인 감염관리지침을 마련하고자 하였다. 대상 및 방법: 1999년 1월부터 2001년 7월까지 2년 7개월간 동아대학교병원 일반병실에서 악성혈액질환으로 항암제 치료를 받다가 조혈모세포이식을 시행받았던 22명을 대상으로 중심정맥관 관련 패혈증의 형태를 비교분석하였다. 결과: 대상 환자들의 일반병실과 무균실에서의 입원기간은 각각 32±13일, 33±19일, 호중구 감소기간은 15±12일, 17±18일, 호중구 감소기간의 발열 횟수는 14회, 14회로서 입원병실의 종류에 따른 차이는 없었다. 환자들의 중심정맥관 사용일수는 일반병실에서 29일(7~545일), 무균실에서 100.5일(25~606일)이었으며, 총 사용일수는 각각 1,515일, 3,250일로서 무균실에서의 중심정맥관 사용일수가 의미 있게 길었다(P=0.001). 중심정맥관 사용 일수에 대한 감염률은 각각 5.28/1,000일, 3.08/1,000일로서 일반병실에서 그 빈도가 높았으나 통계적 유의성은 보이지 않았다(P=0.141). 결론: 중심정맥관 삽입 후 일반병실에서 항암제 치료를 받던 환자가 조혈모세포이식을 위하여 무균실에 입원하는 경우, 중심정맥관을 교체하는 것이 감염관리를 위하여 바람직할 것으로 생각된다. Background: We compared the incidence of central venous catheter (CVC) related septicemia during neutropenic period in the same patient, which developed following chemotherapy for remission induction and consolidation, or hematopoietic stem cell transplantation (HSCT). Methods: We retrospectively reviewed the medical records and laboratory data of 22 patients with hematologic malignancies who received anticancer chemotherapy followed by HSCT at Dong-A University Hospital between January, 1999 and July, 2001. We investigated the duration of hospitalization, duration of neutropenic period, duration of catheterization, microbiologically documented organisms and incidence of CVC related septicemia. Results: The data in general ward (before HSCT) and laminar air flow room (after HSCT) were as follows: duration of hospitalization was 32±13 days and 33±19 days, duration of neutropenic period was 15±12 days and 17±18 days, median duration of catheterization was 29 days (7~545 days) and 100.5 days (25~606 days) (P=0.001), and incidence of CVC related septicemia was 5.28/1000 days and 3.08/1000 days, respectively. In the CVC related septicemia, the most common etiologic organism was coagulase negative staphylococcus. Conclusion: We suggest that the exchange of CVC before admission to laminar air flow room could decrease the incidence of CVC related septicemia in HSCT recipients.

With modern society becoming more fractionated and specialized, social structure becomes more complicated and diversified, thereby resulting in generating a large quantity of information in a moment. In the forms of information communication or delivery, there are various communication methods by letters by means of newspapers, magazines, various document, etc., or sound by means by radio, telephone, etc., or by visual elements such as TV, picture, or photography, illustration, etc. However, a method to visually communicate information has a big advantage in the aspect of effectiveness for it appeals and deliver information to the populace so effectively through a synchronous or simuataneous and intuitive path. After all, as a method to deliver information which completely corresponds to the demand of th present age, it is true that the method gives fully play to its value. Thus, the historical significance of illustration, one of special fields, which performs a role to deliver information, based on such visually sensual images, is now so great, and a condition on that illustration stands out in bold relief has been already created, and therefore its importance is gradually culminating. At such a point of time, since the necessity of illustration rapidly increased socially, and accordingly a number of illustators who are engaging in the field of illustration have so increased quantitively, it is as clear as the light that the qualitative improvement of illustration will be greatly demanded and required in the near future. There would be many factors required as qualitative standards of illustration, and however, among those factors, the characterized or indivisually-oriented expressivity of illustration is deemed to be so important. Such a kind of expressivity, in the first place, objectively helps understanding in the populace's acception of information, and initiatively delivers or communicates the overall intention of information and at the same time, being recognized anew even formatively in the aspect of communication of aesthetic sentiment or feeling, it gives visual charm to the populace and plays as an element to raise the preference of illustration, thereby taking an important part for each author to secure his or her competitive power. This study, in a dimention of researching into the expressivity which can be regarded as a standard to measure the quality of illustration, has a significance to newly suggest the new possibility of expressivity through developement of an expression-oriented proccessor, and at the same time, aesthetic inspiration as well in a multilateral aspect, based on visual formativeness.

The delivery of the proper care to the emergency dental patients is more important in the aspdect of community dental service. To attain such a purpose requires the sacred duty to the training of oral and maxillofacial surgeons. This is a retrospective study on the characteristics of dental injuries and diseases in emergency patients. Ths study was based on a series of 2,649 patients treated as dental emergency patients at K country hospital of medical college, from Jan. 1, 1993, to Dec. 31, 2000. The obtained results were as follows. The trauma(71.6%) was the most frequent cause in dental emergency patients, odontogenic infection and oral hemorrhage were next in order of frequency. The primary interdental wiring and transpalatal wiring were frequent proper methods with rubber drainage for prevention of hemorrhage and infection in the primary care of jaw fracture. The peak incidence(45.0%) about the infection group was occurred in the pulpitis of advanced dental caries, and common treatments were the medication of antibiotics & anagesics and I&D. In the dentoalveolar hemorrhage group, a major cause was postoperative hemorrhage(57.9%) and hemostasis was obtained by pressure dressing, suture and drainage of infected wound. About TMJ disorder group, the peak incidence was showed in the post-traumatic myofascial pain dysfunction syndrome and its primary care was medications(anagesics & sedatives). In the other groups, various irritable specific pains were complained, such as trigeminal neuralgia-form pain, acute stomatitis, chemical burn, terminal stage neuritis of head & nech cancer and their primary care methods were various individually. For the rapid and correct care of the emergency dental disease above, well-trained education should be presented in the intern and resident curriculum of oral & maxillofacial surgery.

The vehicle of recordable communication utilized first in human societies since the appearance of human beings on the earth was pictorial records, i.e., illustration. At one time in human history, charactors were created, thus preparing the means to convey lots of information via letters, without having recourse to drawings. which can be said to bean an epochal event in the history of man. Since then, letters cam to present the limits of expression that symbolization has in itself. It was just the portion of visual descriptions on the circumstances. The domain of painting has not thus far extinct by supplementing the demerit of the letter with drawings, coming to coexist with letters. The vehicle of what is referred to as illustration that has existed with human history obviously represents the nature of current events, and it would not be too much to say that it has sketched phases of human societies in their times. Today what is called current events include every happening, large or small, and significant or insigrnificant, arising from human societies. The illustration can be said to be an expressional domain dealing with current affairs as their themes. This effectively conveys the events occurring to the public from the present time, and simultaneously provides the people with clues for solving their problems via the artist's sharp critic capability or raise issues so as to form a zone of sympathy with the people. This specific role playing of the illustration led itself to be positioned as a domain. The expression of current event based illustration shows an unique artistic tendency of expression to impressively and indivisualistically convey messages, pursuing the enhancement of quality with more satisfaction, apart from merely reporting perspectives. With this in mind, this study made an attempt for groping for a better illustraion based on current events that can be harmonized with the above objectives, along with expectaions and alalyses of illustration works.

A field of science, the illustration which has been always with people since the prehistoric age, has existed with the purpose to talk with of speaking toward the general public and persuade them. Moreover, even though the letters invented for mankind to mutually understand and communicate were born, it is noteworthy that the 'drawings', a visually symbolic language, still plays fully its role and function in human society. Also, as one of the visual mass media, the illustration that was delievered from a big catagory of 'drawings' and which has faithfully performed its role, has played function such as that when it is necessary to mutually understand and communicate through a talk or letter, we can explain and make someone understand what we intend to explain the meaning of situation by means of explaining it figuratively of illustratively, in a visual demension, and at the same time its takes its firm position as a field performing its function to deliever information in the society of the general public. However, the part that should be tried to research into beyond the functional demension of illustration is to secure the aesthetic sense appealing to human sensitivity or sense in a dimension of maximizing its solicitation through the more efficient communication of illustration. Such an aesthetic sense stimulates and induces much of mankind's instinctive sensitivity, thereby becomming itself an important element which heightens more the effect deliver the content. The aesthetic sense basically takes the nature of art as its basis, and such nature of art can be fully played only on the process of reinterpretation through the indivisual idea peculiar to an artist. Therefore, after all such illustration that experiences a process of the conceptual reinterpretation containing the empirical philosophy peculiar to an artist basically deliever information to mankind, and at the same time form or creates a condition through which big inspiration of interest can be aroused even in the aspect of human sentiment through the mankind's aesthetic sense of beauty including the nature of art.

ATM(Asynchronous Transfer Mode) is a transmission technique for the B-lSDN(Broadband Integrated Service Digital Network). Congestion problems are unavoidable in the ATM networks, since various traffic typos coexist in the networks. The preventive congestion control algorithm is widely used for the real time traffics such as voice and video. The reactive congestion control algorithm works well for the non-real time traffic within a short distance. A mixed traffic control algorithm is proposed, which works either preventively or reactively based on traffic types. The proposed algorithm sets a high and low threshold value at the output buffers and modifies the EPRCA(Enhanced Proportion Rate Control Algorithm) to control loss-sensitive cells. Delay-sensitive cells are handled by the priority control and the UPC(Usage Parameter Control) algorithm. The performance analysis shows that the proposed traffic control algorithm works well for both the VBR(Variab1e Bit Rate) and ABR(Available Bit Rate) traffic with small buffers
