악성코드에 대한 보다 바람직한 예방은 클라이언트측이 아닌 서버측에서 이루어지는 것이다. 본 논문에서는 새로운 개념 의 서버용 안티바이러스 엔진인 SAVE 1.0을 설계 구현하여 제시한다. SAVE는 기본적으로 1개의 AV모니터와 다수의 AV에이전트로 구성되어 있는데 다중 CPU를 장착한 병렬처리서버의 특징을 직접 활용하기 위하여 관리자가 다중쓰레드 기법을 직접 지정할 수 있도록 하고 있다 악성코드를 5가지 부류로 구분하여 바이러스 시그너쳐 DB를 구축 제공함으로써 부류별 진단을 지정할 수 있도록 하고 있으며 실시간 네트워크 패킷 검사를 통한 악성코드 유입 점검 기능도 제공한다. 웹 기반의 관리자 인터페이스는 뛰어난 사용자 편의성을 제공하고 있다. 성능실험결과 악성코드 검색율은 국내외 상용제품과 비교해서 매우 우수한 것으로 나타났으며 검색속도에 있어서도 서버의 CPU 수 증가에 거의 선형 비례하여 향상되는 특징을 보이고 있다. It is more desirable to prevent and detect the malicious codes in server system rather than in client PCs. In this paper, we suggest a new anti-virus engine, SAVE 1.0, which is executed on a parallel processing server. SAVE consists of 1 AV monitor and several AV agents. A system administrator can control the degree of multi-thread directly in order to enhance the utilization of parallel processing servers. Virus signature DBs in SAVE are classified into 5 categories, which support system administrator's options to use the classifier or not. By real-time checking of network packets, the influx of malicious codes can be prevented. Web-based GUI is one of the convenient functions provided in SAVE. In performance tests, we have confirmed that SAVE has higher virus detection ratio than any other AV engine, and SAVE has a desirable feature as an software of parallel processing servers since the performance of SAVE is improved almost linearly as the CPUs in a parallel processing server increases.

This article on Educational Autonomy System(EAS) in Korea during 1964-1991 reviews socio-historical backgrounds and the practice of EAS. The article focuses on the autonomy unit size, the organization of Boards of Education, and the quality of the Chief State School Officer. The purpose of this study is to draw lessons from past EAS in Korea which should serve as a future direction for improvements. The major findings are as follows: First, Educational Autonomy System during 1964-1991 was not adequately decentralized as the size of the distract unit was in appropriate, and the relationships among School Boards of Education, the Ministry of Education and the State Department of Education were not healthy. Second, EAS during 1964-1991 had problemss in Boards of Education, organization and operation aand the ppuublic could not have firm control over major policy decisions. Third, EAS during this period was too much dependent uppon thee generral administration, and the last finding is that under this period the key personnel for educational addministration were not adequately qualified for fulfilling their roles.

The number of colleges and college students has shown rapid increase since the Liberation of 1945. In the process of its increase there has been continuous debate on improving the quality of education in general. Liberal education not only plays an important role in college curriculum, but also becomes hot issues in the course of revising the curriculum for the coming century. This paper is present the basic direction and the standard of liberal education and further to develop an independent model for Yong-In University in the future. The Paper begins with the review of Philosophical foundations of liberal education. More specific detail comes with the objective of the issues. Developing a model for Yong-In University remains as an assignment for future research. As Harvard University developed independent and creative liberal education program through Red Book and Columbia did through Carmen Report since 1960, it is proper to have sound discussion for the betterment of curriculum for college students.

The purpose of this study analyzes preconception that students have about electricity in the 4-th graders of elementary school. The results are as follows; First, grade 4 elementary school students who learn with a first curriculum of science had many misconception. It is a because that the language use which goes wrong and students have experience only the actual condition regarding as electricity before the electric concept is formed. second, the students think that recording where the volt will be high non dawns. And Students had misconception that light is changed by location of front line or the light bulb. Moreover the students didn't make a idea of electrical circuit. Third students had misconception that the light bulb comes to brighter according as battery is more. This is because that students compose the concept of electricity from an experience.

In the view of the results investigated the effect of air pollutants that is emitted from a new generator facilities, the total estimated concentration which is the summation of a contributional concentration and observational concentration is much less than that of atmospheric environment criterion for the air pollutants. So we can predict that the operation of the new generator facilities with mitigation equipment don't seriously affect around environment. At the same time, we compared the contributional concentration of before mitigation equipment with that of after it to examine the decreasing amount due to mitigation equipment. The result showed that the concentration of SO2, NO2 and PM-10 is reduced to 25%, 30% and 26% of original value, respectively.

To predict reasonably the movement and the concentration of the pollutants in the coastal area. A simulation model should be prepared considering detail topography with land-sea and the urban effects, and the resolution near the source. The explicit method can not be applied due to the unstability of the numerical calculation in high horizontal-grid resolution, while the ADI scheme satisfied with the high horizontal grid resolution and can be used in the fine mesh system which shows the detail topography, atmospheric flow. The ADI method which studied the high horizonal grid resolution was excellent. The two dimentional model used in the study using ADI method is proved as a reasonable model to predict the wind field in any small scale area including mountainous coastal urban area.

목적: 급성 파종성 뇌척수염은 감염이나 예방 접종 후 발생하는 중추 신경계의 급성 자가 면역 염증성 질환으로 탈수초를 일으킨다. 신경학적인 증상으로 발현되고 대부분 환전히 회복되지만 신경학적 후유증을 남기거나 사망 할 수도 있다. 이에 저자들은 본원에서 발생 한 14명을 분석하여 조기 진단과 치료에 도움을 주고자 하였다. 대상과 방법: 1998년 3월부터 2003년 8월까지 이대목동병원에서 급성 파종성 뇌척수염으로 진단 받은 14명의 의무기록을 후향적으로 조사하였다. 결과: 환자들의 평균 발생 연령은 5±7.8개월이였고, 특정계절이나 연도에 집중되어서 나타나지는 않았다. 선행질환은 주로 비특이적인 상기도 감염이 가장 많았고, 초기증상으로는 경련이 가장 많았다. 그 외에 의식저하나 운동장애도 있었다. 뇌척수액 검사에서 백혈구 증가증이 발견된 경우는 있었으나 단백이 증가된 경우는 없었다. 뇌 자기공명 촬영에서 T2 증강시 뇌백질과 기저핵에 고음영의 다발성 병소가 발견되었고 추적 촬영에서 대부분에서 소실되었다. 뇌파 검사가 시행되었던 경우 전반적인 서파가 가장 많았고 국소적인 극파가 나온 경우도 한 명 있었다. 환자들은 정맥 면역 글로블린과 메틸프레드니졸론으로 치료하였고 치료 시작 후 3~7일내 증상이 호전되었다. 모든 환자를 2달 이상 추적 관찰하였고 항경련제가 지속적으로 필요한 정도의 경련성 질환이 두 명, 신경아교증이 남아잇는 경우가 한 명, 외래에서 다발성 경화증이 의심되는 경우가 한 명 있었다. 결론: 급성 파종성 뇌척수염은 침범 부위에 따라서 다양한 임상 상으로 나타나며 면역 글로블린과 메틸프레드니졸론이 치료에 효과적이였다. 본 연구에서는 대상 환자수가 적어 신경학적 후유증의 위험요소는 밝힐 수는 없으나, 예후는 검사소견과 연관되어 있지는 않았고, 대부분에서 양호하여 완전히 회복되었으나, 신경학적 후유증이 남은 경우도 있었다. Objective:Acute disseminated encephalomyelitis(ADEM) is an acute demyelinating autoimmune inflammatory disease of the central nervous system which develops after infection of vaccination. It may be fatal, and produce a permanent residual static disability or fully recover. We retrospec-tively studied 14 cases to investigate the clinical findings and outcome of ADEM. Methods : 14cases of ADEM diagnosed at Ewha Womans University Mokdong Hospital from 1998 to 2003 were retrospectively reviewed. Results : The age of onset was 5years±7.8 months and no seasonal clustering was found. The time of onset of symptoms was between 3 to 30 days. The preceding events were nonspecific upper respiratory infections in 9 cases, aseptic meningitis in 4 cases, and gastroenteritis in one case..The initial symptoms were seizure, altered consciousness, hemiparesis, fever, headache, and vomiting. Brain MRI showed multifocal high signal intensity lesions on T2 weighted image mainly in the cerebral whith matter, basal ganglia and periventricular white matter. EEG was performed in some cases and showed generalized or focal slow waves and only one case showed focal spikes. Patients were treated with IV globulin and methylprednisolone and the symptoms improved within 3-7 days after treatment. All patients were followed up for more than 2 months and most of them fully recovered except two. Conclusion : ADEM presents in various clinical manifestations depending on its involvement of the brain lesions. Most cases recovered fully but in some cases, residual permanent neurologic sequelae remained.

Background The Pilates method has recently been recommended as the best way to improve spinal stability by strengthening the trunk and gluteus maximus (GM) muscles. Purpose In this study, we compared trunk and GM muscle activities and pelvic rotation angles during four traditional Pilates exercises. Study design Cross-sectional study Methods Twenty healthy volunteers were recruited for this study. During the four exercises, the activity of the trunk and GM muscles were measured via electromyography and pelvic rotation was measured using a smart phone-based measurement tool. Results The activities of the transverse abdominis/internal oblique and external oblique muscles were highest during the leg pull front (LPF) compared to the other exercises. GM activity was significantly higher during the LPF compared to the shoulder bridge and swimming (SW), but not during the one leg kick (OLK). Multifidus (MF) activity was significantly higher during SW than during the other exercises. There were no significant differences in MF activity between the SW and OLK exercises. Pelvic rotation angle was significantly reduced during the OLK compared to the LPF (p=0.004). Conclusions We recommend the LPF exercise if the goal is increased trunk and GM muscle activity and the SW exercise if you target for increased MF activity. The OLK exercise is useful for activating the trunk and GM muscles while reducing uncontrolled pelvic movements.

Neoadjuvant chemotherapy with a combination of vinblastine, bleomycin, and cisplatin(VBP) followed by surgery in locally advanced squamous cell carcinoma of the vulva : A case report

A 56-year-old female was referred to our gynecological department for evaluation of the vulvar ulceration. The patient suffered from vulvar burning sensation. Physical examination revealed an approximately 7 cm in diameter exophytic cauliflower-like mass with ulcerative growth that involved the both labia minor and the perineum. And both enlarged inguinal lymph nodes were palpable. The serum squamous cell carcinoma antigen level was 4.3 ng/ml. Punch biopsy was performed and the result was reported as SCC of the vulva. Computed tomography showed an enlarged (>5mm) lymph nodes metastasis in the both groin. Due to bulky mass in the vulva, the patient underwent neoadjuvant chemotherapy(NACT) with VBP(vinblastine 4 mg/m2 plus bleomycin 25 mg and cisplatin 50 mg/m2). After the three courses of chemotherapy, the vulvar lesion was greatly reduced in size, while the both groin lymphadenopathy remained unchanged. Subsequently, a radical vulvectomy with bilateral inguinofemoral lymphenectomy was performed. The final histopathological reports of the surgical specimen demonstrated a moderately-differentiated invasive squamous cell carcinoma with negative resection margin. Lymph nodes were positive for metastasis (right inguinal: 3/8, left inguinal: 1/7). 2 month later the surgery, the patient received adjuvant radiotherapy of the vulvar and inguinal regions bilaterally. (external-beam irradiation, 1.8 Gy/day in 25 fractions over 5 weeks ; total radiation dose, 45.0 Gy) Optimal treatment of locally advanced, inoperable vulvar cancer is still debatable. Our case illustrates that NACT with VBP showed significantly decreasing in tumor burden with manageable toxicity. In conclusion, NACT with VBP may increase surgical feasibility in initially unresectable tumor, decrease the deleterious side effect of radiotherapy. Therefore, the use of neoadjuvant chemotherapy followed by surgery could be considered as a therapeutic option for locally advanced vulvar cancer.

The From “the Memorial Service for Confucius” to “the Ritual of Shi Dian for Sage Confucius” -A consideration for formation Process of The Shi Dian Ritual in Han-Tang Dynasty

( Yoo Eun Joo ) 성균관대학교 유교문화연구소 2011 儒敎文化硏究(中文版) Vol.0 No.16

在本論文中, 筆者把在闕里孔氏家廟擧行的孔子之祀, 作爲“聖孔釋奠禮”的直接來源, 討論了孔子之祀釋奠化成爲“聖孔釋奠禮”的全過程及其動因。其主要內容包括以下三点。 一、“聖孔釋奠禮”的形成肇始于孔子之祀的國家祀典化。兩漢之際, 儒家思想在政治上受到很大重視, 不僅如此, 因谶緯的推廣, 孔子的存在被認爲與漢朝的正統性直接相關, 他的地位亦不斷被提高, 幷由此逐漸被神聖化了。在這種環境下, 國家開始控制孔子之祀。朝廷封賜孔子后裔爵位, 使他們奉孔子之祀, 這種措施不僅使孔子后裔開始具有官方的身分, 而且突出了國家在孔子之祀中的地位。東漢初期, 朝廷已經使地方長官或敎學官在郡、縣、道的學校擧行孔子之祀, 這標志着, 在闕里家廟以外的地方所擧行的孔子之祀確是國家祀典體系的一部分。到了東漢末年, 朝廷進一步在闕里孔廟設置專職官員, 負責孔子之祀, 幷且其相關費用亦由政府承擔, 由此, 在闕里孔氏家廟所擧行的孔子之祀與在其他地方所擧行的孔子之祀, 都完全被納入了國家祭祀的范圍之中。 二、國家祀典化了的孔子之祀走出闕里家廟, 走進太學, 以“釋奠”之名重生, 進一步接近“聖孔釋奠禮”的完成。曹魏之際, 孔子之祀作爲帝王敎育的一部分進入太學, 成爲釋奠禮。到東晋以后, 釋奠禮結合了講儒經的活動, 共同構成皇位繼承的通過儀式, 象征了皇位繼承者之資格的獲得和完成。釋奠禮關系到皇位繼承, 起着象征皇權正統性的作用。因此, 皇太子與少年天子擧行的釋奠禮不再是簡單的學禮, 而是隆重的國家大典。這樣, 當時就有必要創建合适的禮儀場所, 所以東晋孝武帝以后開始倣借闕里孔氏家廟, 在太學創建了釋奠禮的專用場所――孔子廟。 三、唐朝完成統一之后, 在六朝時期國家正統觀念――儒敎的影響下, 關系到皇位繼承的釋奠禮, 逐漸得到與新王朝統治原則相适應的整備, 幷最終定型, 成爲“聖孔釋奠禮”。在這一進程中, 玄宗出于以孝道爲代表的自己政權權威的考慮, 樹立了“以孝治天下”的統治原則, 幷爲此積極推行孝道思想, 樹立孔子與儒學的權威地位。在這種環境下, 周公退出官學聖賢之祀, 釋奠禮主享孔子最終定型。皇太子釋奠禮亦成爲奉皇帝之命擧行的釋奠禮的最高層次。 總之, 縱觀“孔子之祀”成爲“聖孔釋奠禮”的全過程, 可以看出, 其變化的動因在于儒敎的時代地位和執政者的統治原則。在歷史上, 對孔子的祭祀儀式, 扮演了執政者將自己的統治原則明示于天下的主要象征性工具的角色。漢唐釋奠禮的形成過程就顯著地表明了這一点。漢唐釋奠禮承擔的時代功能及由此衍生的形式上的定型, 成爲后代釋奠禮的藍本。 In this paper, I regard “the memorial service for Confucius(孔子之祀)” held in the family shrine of Que-Li(阙里) as immediate source of “the Ritual of Shi Dian for Sage Confucius(圣孔释奠礼)”, and is dealing with the whole process and motives of “the memorial service for Confucius” shaping into “the Ritual of Shi Dian for Sage Confucius”. The main arguments of this paper are as below. First, the beginning of “the Ritual of Shi Dian for Sage Confucius” started from the Imperial House holding Ritual Practices of “the memorial service for Confucius”. In Han Dynasty reign period, Confucianism has a very important rule in dominant groups, and especially “Prognostication and apocryphal texts (谶纬)” which had been widely spread throughout society in that time provided a occasion for justifying of Han Dynasty’ rules. Through a series of this process, Confucius has gradually been sacralized and at the same time the status of him and his family was ascended. For instance, The Imperial Government conferred the title of nobility on descendants of Confucius, made them hold “the memorial service for Confucius”. This measure means that descendants of Confucius are in the Imperial Government service through directly performing sacrificial rites for Confucius. Furthermore, in the early years of the Eastern Han Dynasty, government newly started to appoint local officials engaging in “the memorial service for Confucius” in the schools of every region. In the late of the Eastern Han Dynasty, government after all set up official position in government center in mainly performing “the memorial service for Confucius” in the family shrine of Que- Li(阙里), and stood all the expenses for it. Through this process, “the memorial service for Confucius” that is initially held in the family shrine and in the schools of the regions, finally was enrolled into official institutions and system of the State cult practices. Second, “the memorial service for Confucius” as a royal ritual practices in the beginning takes the family shrine of Que-Li(阙里)’s form, but after go through a series of measures taken by a few of top rulers it eventually was reborn in form named “the Rituals of Shi Dian(释奠礼)” at the Imperial Academy(太学), That is nearly similar to “the Ritual of Shi Dian for Sage Confucius(圣孔释奠礼)” in form and procedure. In the CaoWei Dynasty(曹魏)’periods, “the memorial service for Confucius” served to one of the main parts of education for emperors got in the Imperial Academy, at that time, it was ascended official performance called “the Ritual of Shi Dian”. Since the Eastern Jin Dynasty(东晋), “the Ritual of Shi Dian” had started to get out of simple performance form and pattern and gradually had have a various and complex functions. For example, that is combined with lectures on Confucian Scriptures in the Imperial Academy, the symbolization of the rites of passage for succession to the Imperial Throne, confirmation and completion of qualification for succession to the Imperial Throne, and so on. Since this time “the Ritual of Shi Dian” centered in the Crown Prince and the Juvenile Emperor was not simply a sort of one-dimensioned simple ritual, but rather at least had embodied in royal family’s dignity and its supreme authority. For doing this ends appropriately and well, most of all the most important thing was to construct place for “the Ritual of Shi Dian”. And so, since XiaoWu Emperor(孝武帝) of the Eastern Jin Dynasty, the ruler group founded a sort of sacred place-the Kong temple(孔子庙) on the basis of the Confucius shrine of Que-Li(阙里), in the Imperial Academy. Third, after Tang Dynasty unifying a whole nation, the development of “the Ritual of Shi Dian” gradually has been in lined with the rule principle of New Kingdom, finally became “the Ritual of Shi Dian for Sage Confucius”. In this process, XuanZong(玄宗) made big contributions in this trends, he putted emphasis on dominance by Confucian virtues, especially by “Filial piety”. Due to his vigorous effort, during his reign, along with the thought of loyalty and filial rapidly spread on the whole nation, the status and authority of Confucius and Confucianism also naturally been established. From this time, ZhouGong(周公) naturally was thrown out in the memorial ceremony for the Sages performed by government school, only Confucius put down roots in performance of “the Ritual of Shi Dian”. Since this time, “The Shi Dian Ritual of the Crown Prince” has become the grandest ritual for Confucius that was held by Emperor’s commands himself. In conclusion, the whole process and development of “the memorial service for Confucius” becoming “the Ritual of Shi Dian for Sage Confucius” shows the fact that the result of Emperor’s political belief and practice being mainly based on Confucianism’s values and continually effort to spread them into whole nation by intension. So “the Ritual of Shi Dian for Confucius” institution and its functions eventually symbolize the groundings of each ruler’s legitimate reign and authority, which is mainly due to the political ideals of Confucianism, namely the dominance on virtues.
