사이버 공격이 더욱 지능화됨에 따라 기존의 침입 탐지 시스템(Intrusion Detection System)은 기존의 저장된 패턴에서 벗어난 지능형 공격을 탐지하기에 적절하지 않다. 딥러닝(Deep Learning) 기반 침입 탐지는 새로운 탐지 규칙을 생성하는데 적절하다. 그 이유는 딥러닝은 데이터 학습을 통해 새로운 침입 규칙을 자체적으로 생성하기 때문이다. 침입 탐지 시스템 데이터 세트는 가장 널리 사용되는 KDD99 데이터와 LID-DS(Leipzig Intrusion Detection-Data Set)를 사용했다. 본 논문에서는 1차원 벡터를 이미지로 변환하고 CNN(Convolutional Neural Network)을 적용하여 두 데이터 세트에 대한 성능을 실험했다. 평가를 위해 Accuracy, Precision, Recall 및 F1-Score 지표를 측정했다. 그 결과 LID-DS 데이터 세트의 Accuracy가 KDD99 데이터 세트의 Accuracy 보다 약 8% 높은 것을 확인했다. 또한, 1차원 벡터에 대한 데이터를 Kibana를 사용하여 데이터를 시각화하여 대용량 데이터를 한눈에 보기 어려운 단점을 해결하는 방법을 제안한다.

Background : Gastric cancer is the most common malignant tumor in Korea. surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for recucing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and unplanned readmission rate between the pre-pathway group(n=67) and the post-pathway group(n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days(p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was of satistically significant(p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korea hospital settings.

Through the study of successive literatures form the Han-dynasty(漢代) when 《Keumjweyeuliak(금궤요략)》 was written to modern age, we inspected many types of Onkyungtang(溫經湯) and prescriptions including the term of ' Onkyung(溫經)' or Chokyung(調經)', and look into their composition and symptoms respond to administration of this medicine. The results of this study were as follows; 1. The medicine which makes up Onkyungtang was 38 kinds from the Han-dynasty to the Chung-dynasty(淸代), and up to the present it summed into 43 kinds. 2. Onkyungtang which was composed of different kinds of medicine was 10 types from the Han-dynasty to the Chung-dynasty and added 11 types in modern days. Therefore it sumed up into 21 types. 3. No Onkyungtang is seen more common than that of the same composition as in 《Keumjweyeuliak》 in successive literature. The next is the same constituents as in 《Buinyangbangdaejeon(婦人良方大全)》. Others were rare. 4. Onkyungtang in《Keumjweyeuliak》was used to treat cold syndrome of the penetration and conception vessles or uterus of deficiency type and that in 《Buinyangbangdaejeun》was for cold syndrome of the penetration and conception vessels or uterus of excess type. 5. Other names of Onkyungtang in《Keumjweyeuliak》were Daeonkyungtang(大溫經湯), Chokyungsan(調經散), Chokyungtang(調經湯), Chunkeumchokyungtang(千金調經湯), Chunkeumchokyungsan(千金調經散) and Soonkyungtang(小溫經湯). And the prescription in the same constitution was also called Chungkyungonkyungtang(仲景溫經湯), Keumkweonkyungtang(금궤온경탕) and Sibbionkunghwan(十二溫經丸). 6. Onkyungtang in 《Buinyangbangdaejeon》was called Soonkyungtang(小溫經湯) and the very prescription was also called in the name of Yangbangonkyungtang(良方溫經湯), Jinmionkyungtang(指迷溫經湯), Kungkwiinkyungtang and Jinssionkyungtang(陳氏溫經湯).

Retroperitoneal fibrosis is a fibrotic process of the retroperitoneum that frequently produces ureteral obstruction. It can occur as an idiopathic disease or in association with various non-malignant and malignant condition. In the early phase of the retroperitoneal fibrosis ; symptoms originate from the disease process itself, while in the late state the clinical features represent the effect of obstructive uropathy and renal failure. Treatment consist of steroid therapy, urinary diversion and ureterolysis with jntraperitonealization or lateralization or wrapping with omentum. Herein we present 5 cases of retroperitoneal fibrosis.

"Journal of Korean Academy of Adult Nursing" has been published since 1989 and more than 330 articles have been published up 2000. We reviewed all the articles published in this journal to analyze the contents and trend of published articles and to find out the way of improvement both in quantity and quality of studies in this area. The results are as follows : 1) Ninety percent of articles were quantitative studies. Experimental design was used in 16.1% and quasi-experimental design was adapted in 73.6% of articles. Qualitative research were 10.3% of total articles reviewed. 2) Only 5.1% of articles described theoretical framework and 73.6% of experimentally designed articles included research hypotheses. 3) Among experimental studies, only one was true experimental studie design. Eighty nine point three persent had descriptive survey method among non-experimental studies. Amog the thirty four qualitative studies, phenomenologic(73.5%), grounded theory(14.7%), and ethnographic (11.8%) design were used. 4) Most of research subject were patients and few healthy people, healthcare worker, and patient family. 5) Psychosocial data collection method which used questionnaire were 53.7% and interview. physical measurement, observation were used in 22.8%. 8.2% 5.4% of articles respectively. 6) Total number of keywords were 692, and average number of key words per article was 2.2. Health-related keyword was the most frequently used according to four metaparadigm of nursing (human, health, nursing, and environment). Environment related keyword was rarely appeared. The number and quality of nursing research in "Journal of Korean Academy of Adult Nursing" have been improved continuously. It is difficult to find out special trend or characteristics which is unique in this journal because of relatively short history of adult nursing studies. This review study was performed to analyze adult nursing studies only in the view of quantitative aspect, but it is needed to analyse qualitatively to find philosophical or theoretical trend in nursing.

Micro SIM Card Socket에 사용된 Push-Push Type 기구의 다물체동역학 해석

최찬규,김주철,윤주영,심정길,유홍희,Choi, Chan Kyu,Kim, Ju Chul,Yun, Ju Young,Sim, Jung Kil,Yoo, Hong Hee 대한기계학회 2013 대한기계학회 논문집. Transactions of the KSME. C, 산업기술과 혁신 Vol.1 No.1

SIM card socket은 USIM 카드를 휴대폰에 고정시키기 위하여 많이 사용되며 사용자의 편의를 위하여 push-push 기구를 많이 사용하고 있다. Push-push 기구는 하트-캠 구조에 의해 작동되며 사용자가 USIM 카드를 한번 눌러주면 삽입이 되면서 locking, USIM 카드를 다시한번 눌러주면 토출이 되면서 unlocking이 되는 기구이다. Push-push 기구는 주 스프링에 의해 구동되는데 주 스프링에 의해 캠 슬라이더와 캠 스틱에 응력이 발생하여 기구가 파손되기도 한다. 따라서 push-push 기구 동작 시 발생하는 응력을 반드시 고려한 기구 설계가 필요하다. 기존의 기구 설계 방식은 정적인 응력해석 결과만 사용한 방식을 사용하였다. 하지만 기구 특성상 동작 시 충격력이 반드시 발생하기 때문에 충격력에 의해 발생하는 동응력을 해석하고 기구 설계에 반영하여야 한다. 본 논문에서는 push-push 기구 동작 시 발생하는 동응력 해석을 위하여 push-push 기구의 유연 다물체 동역학 모델을 개발하고 기구 동작 시 발생하는 동응력을 해석하였다. A SIM card socket is used for a cell phone to fix an USIM card and a push-push mechanism is typically employed in the SIM card socket for a user convenience. A SIM card is inserted with locking when a user pushes the card once and a SIM card is removed with unlocking when a user pushes the card again. A push-push mechanism is operated by a heart-cam structure and a main spring. A cam slider and a cam stick consisting a push-push mechanism may be broken because of the main spring. So, dynamic stress at a cam slider and a cam stick which is generated by a main spring during operating should be analyzed and considered in the push-push mechanism design. In this paper, a flexible multibody model of a push-push mechanism was developed to analyze dynamic stress at a cam slider and a cam stick.
