Previously, Gum Metal (Ti-24(Nb + Ta + V)-(Zr, Hf)-O (at%)) exhibiting an ultralow Young`s modulus, ultrahigh strength and super elasticity was developed by Saito et al., who proposed that three electronic magic numbers, an average electron/atom (e/a) ratio of 4.24, an average bond order (Bo) of about 2.87, and an average “d” electron-orbital energy level (Md) of about 2.45 eV, should be satisfied simultaneously to obtain such “super” properties. The purpose of this study was to find new alloy systems possessing those properties and to examine the effect of beta equivalent content ([Mo]eq) on Young`s moduli of new alloys having the same three electronic numbers mentioned above. It was found that not only three electronic numbers but also [Mo]eq should be considered to obtain a similar Young`s modulus and hardness with respect to the Gum Metal.

Purpose: This study was conducted to investigate the extent of diffusion of Intravenous infusion nursing practice guideline among nurses in advanced general hospitals and general hospitals in Korea. Methods: The subjects were 234 nurses who practice the intravenous infusion in 24 advanced general hospitals and general hospitals. Data were collected between October 5 and November 2, 2015 by mail (return rates: 97.5 %). Data were analyzed using descriptive statistics, t-test, and ANOVA with SPSS/ WIN 21. Results: The average guideline diffusion score and levels of diffusion was 3.39±0.58 (level of “use sometimes”). 44 recommendations (46%) were in level of “use always” and 50 recommendations (53%) were in “use sometimes”. Extent of diffusion were significantly different according to present status (F=2.81, p=.040) and education (F=4.35, p=.014). The facilitating factors to use the guideline were education by department of nursing service, convenient composition of guideline and barrier factors were “no time to use the guideline”, “don’t know the guideline” and “there is no guideline at ward”. Conclusion: Extent of diffusion of Intravenous infusion nursing practice guideline among nurses was moderate level. The strategies for promoting the implementation of guideline in clinical practice is needed. Further study of outcome evaluation of guideline implementation will be needed.

Background: To describe the first experience of case-based advanced cardiac life support(ACLS) course in Korea. Methods: We have given case-based ACLS course to 13 nurses(6 emergency nurses, 4 coronary care unit nurses, 3 professors) and 17 physicians(4 emergency physicians, 12 emergency residents, 1 intern). We performed the case-based ACLS course according to 1992 American Heart Association guidelines and recommendations for advanced cardiac life support by american ACLS instructors(1 pulmonologist, 4 critical care nurses). We performed final theoretical written test and 2 times written survey (immediate and 100th day after the course) about the course. Results: On final written test, all practitioners answered at least 70% of the questions correctly. There was no significant difference between nurses and physicians(86.2±3.6 of physicians and 82.5±6.8 of nurses, p=0.06). 90% of participants considered that case-based advanced cardiac life support was acceptable. 100th day after the course, 93% of participants answered that ACLS course have been helpful on his/her job and also want retraining of ACLS course. 70% of participants considered that ideal ACLS training committee in Korea is the Korean Society of Emergency Medicine. Conclusion: Case-based ACLS course is a useful educational method for physicians and nurses in Korea. In the future, we should organize Korean resuscitation committee and then make guidelines for ACLS, and then continuously educate physicians and nurses.

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.

유은정,우행원,김영철,연규월,김종원,임원정 대한신경정신의학회 2000 신경정신의학 Vol.39 No.2

연구목적: 1980년 중반부터 강박장애의 치료로 SSRIs가 널리 쓰이고 있으나 치료반응의 예측인자에 대한 연구는 미비한 실정이다. 본 연구에서는 sertraline 투여후 호전군과 비호전군의 인구학적 특성, 발병연령, 이환기간, 과거의 강방장애에 대한 투약경력, 정신과 질환의 가족력, 증상의 심각도, 임상양상 등의 변수들을 관찰하여 sertraline 치료반응과의 상관관계를 살펴보았으며 치료방응을 예측 할 수 있는 인자를 알아보았다. 방법: 연구 대상은 이대부속 동대문병원 정신과에 입원 또는 외래치료를 받은 환자들 중 정신과 진단 편람제 4판 진단 기준에 의거하여 강박장애로 진단 받은 31명(남자 10명, 여자 21명)이었다. 연구 방법은 sertraline을 하루 50mg씩 투약하면서 Y-BOCS, NIMHOCS, CGI로 강박증상의 변화를 평가하였고, HAM-A로 불안정도의 변화를 측정하여 투약 전 점수와 비교하였다. 결과: 1) Y-BOCS 점수 40%이상 감소와 함께 CGI 점수 2점 이상 감소를 보인 호전군은 대상환자 31명중 17명(54.8%)이었고, 비호전군은 14명이었다. 호전군이 비호전군에 비해 늦은 나이에 발병하는 경향을보였고(p<0.1), 이환기간이 짧았으며(p<0.05), 과거의 강박장애에 대한 투약경력은 적었다(p<0.05), 정신과 질환의 가족력은 두 집단간에 차이가 없었다. 2) 호전군에서 투약 전 Y-BOCS의 강박행동 점수가 유의하게 낮았으며(p<0.05), 기타 다른 평가척도에서는 두 집단간에 유의한 차이가 없었다. 3) 평균 Y-BOCS 점수는 투약 전에 비해 sertraline 투약 12주째 43.5%가 감소하였다. 투약 전과 비교하여 투약 2주째부터 불안을 평가하는 HAM-A 점수가 유의하게 감소하였고, 투약 4주째부터 Y-BOCS, NIMHOCS, CGI 점수가 유의하게 감소되기 시작하여 12주까지 지속되었다.(p<0.01). 4) 호전군에서 오염에 대한 강박사고와 씻음의 강박행동의 유의하게 많았으며(p<0.05), 셈의 강박행동은 없었다(p<0.05), 병적 의심은 비호전군에서 많은 경향을 보였다(p<0.1). 결론: 이상의 결과를 종합하면, 질병의 이환기간이 짧으며 과거의 강박장애에 대한 투약경력이 적고 투약 전강박행동이 심하지 않으며, 주된 임상양상이 오염에 대한 강박사고와 씻음의 강박행동인 경우 sertra-line에 좋은 치료반응을 보이지만, 셈의 강박행동이 있는 경우에는 치료반응이 좋지 않다고 예측할 수 있다. Objectives: The pharmacologic treatment of obsessive-compulsive disorder(OCD) with serotonergic antidepressant agents is well established in clinical psychiatry on the basis of serotonin hypothesis. Studies on predictive factors of treatment reponse to OCD are relatively scarce. The author compared the demographic factors, age of onset, length of illness, family history of mental illness, previous drug history for OCD, severity and type of symptoms between the drug reponders and non-responders to find out the predicitive factors that may be related to treatment response. Methods: The subjects were 31, both inpatients and outpatients who met the diagnostic criteria for OCD by DSM-IV and scored 20 or higher on the Yale-Brown Obsessive-Com-pulsive Scale(Y-BOCS) completed 12-week trial of sertraline. Y-BOCS, National Institute of Mental Health Obsessive-Compulsive Scale(NIMHOCS), Clinical Global Impression Scale(CGI) were scored to measure the changes of obsessive-compulsive symptoms, and Hamilto Anxiety Scale(HAM-A) was measured at each visit. Results: 1) The responders, defined as achieving at least a 40% decrease in the Y-BOCS total score and more than a 2 point decrease in CGI score, were 17(54.8%), and non-responders were 14(45.2%). Responders tended to show later onset(p<0.1), and shorter duration of illness(p<0.05), and less previous drug therapy for OCD(p<0.05) than non-responders. There were no significant differences in family history of mental illness between the two groups. 2) The basline Y-BOCS compulsive score was significantly lower in responders(p<0.05), although there was no significant difference in the basline severity of other measures. 3) The obsession of contamination and washing behaviors were more frequent, but compulsive counting was not shown, in responders(p<0.05). The pathological doubt tended to be more common in nonresponders(p<0.1). Conclusions: In summary, the patients with shorter duration of illness, less prior drug ther-apy for OCD, and less severe compulsive behaviors, and the obsession of contamination and washing behaviors are expected to be better outcome with sertraline, whereas compulsive counting are the predictor of poor response.

The purpose of this study was to investigate the effect of proprioceptive neuromuscular facilitation (PNF) approach on the spasticity of affected side in patients with hemiplegia, Three subjects with hemiplegia participated in this study. In single-subject research design (a multiple baseline across individuals) was employed in this study. The intervention program including PNF to the unaffected side was introduced for 30 minutes each day during each intervention phase. Muscle tone of affected side was measured with Tone Assessment Scale, and active hip abduction distance of affected side was taken with the subject supine. And then the muscle tone and the hip abduction distance were measured again 30 minutes later following the intervention. The results showed that the PNF application had some beneficial effects on both muscle tone and active hip abduction. This results suggests that PNF application to non-paretic limb can be effective in reducing muscle tone and improving hip abduction range on paretic limb in persons with hemiplegia. However, further research is needed to prove the effect of PNF application on functional improvement.
