This research investigates the impacts of information security (IS) culture and management leadership styles on employee's security behaviors (IS policies compliance, IS participation) in financial institutions. This study use the survey data collected from 236 employees of financial institutions. This research shows that IS culture has a positive effect on both behavioral intentions to comply with IS policies and the intentions to actively participate in information security activities. Transactional leadership has a positive impact on the IS policies compliance intentions and to participate in information security activities. In contrast, transformational leadership has a positive impact on the intentions to participate in information security activities, but not on the IS policies compliance intentions.

Mica capacitor is being adopted for high voltage firing unit of guided weapon system because of its superior impact enduring property relative to ceramic capacitor. Reliability of localized mica high voltage capacitors was verified through environmental test like terminal strength test, humidity test, thermal shock test and accelerated life test for application to high voltage firing unit. Failure mode of mica capacitor is a decrease of insulation resistance and its final dielectric breakdown. Main constants of accelerated life model were derived experimentally and voltage constant and activation energy were 5.28 and 0.805 eV respectively. Lifetime of mica capacitor at normal use condition was calculated to be 38.5 years by acceleration factor, 496, and lifetime at accelerated condition and this long lifetime confirmed that mica high voltage capacitor could be applied for firing unit. 마이카 커패시터는 세라믹 커패시터에 비해 내고충격 특성이 우수하여 다양한 유도무기체계의 고전압 기폭장치에 적용된다. 본 연구에서는 국산화된 마이카 고전압 커패시터의 고전압 기폭장치 적용을 위해 단자강도시험, 내습성시험, 열충격시험과 같은 환경시험과 함께 가속 수명 시험을 진행하였다. 마이카 고전압 커패시터의 고장모드는 절연저항 감소 및 이를 통한 절연 파괴이다. 가속수명모델의 중요 상수를 실험적으로 도출하였으며 전압계수 n 및 활성화 에너지 E_a는 각각 5.28 및 0.805 eV이었다. 가속모델식을 이용하여 도출한 가속계수는 496이었으며 가속수명시험을 통해 도출된 정상 사용 조건에서의 마이카 고전압 커패시터의 수명은 38.5년으로 기폭장치 적용에 문제가 없는 것으로 확인되었다.

박성환,김기영,진량,이재헌,Park, Seong-Whan,Kim, Kee-Young,Chen, Liang,Lee, Jai-Heon 한국식물생명공학회 2002 식물생명공학회지 Vol.29 No.2

Suppression subtractive hybridization (SSH)를 통해 저온에 의해 발현이 유도되는 cDNA들을 분리하였고, 그 중 하나인 slti182는 asparaginase 유전자들과 높은 유사성을 보였다. Slti182의 전체 cDNA인 GmASP1은 1258 bp 길이에 326개 아미노산으로 구성된 긴 Open reading frame (ORF)를 포함하고 있었다. GmASP1 단백질은 애기장대의 putative asparaginase (AB012247)와 84%의 유사성을 보였으나, 애기장대의 다른 isoform(Z34884)와는 55%의 유사성을 나타내었다. GmASP1 유전자는 저온 처리 후 3시간째부터 발현이 유도되어 6시간째에 최대발현을 나타내었고, 이후 점차 감소하여 48시간에는 저온처리전 수준으로 되돌아왔다. 또한, 식물체를 저온에서 48시간 둔 후에 다시 상온으로 옮겼을 때, 정상수준으로 떨어진 GmASP1의 발현이 다시 증가하는 양상을 보였다. 이러한 결과로 볼 때, GmASP1이 저온 스트레스에 반응 초기의 단백질 합성 촉진에 중요한 역할을 할 것으로 사료된다. Suppression subtractive hybridization (SSH) was used to isolate wound-induced cDNAs from wounded soybean. One of low-temperature-inducible cDNA, slti182 showed high homology with genes encoding 1-asparaginase. The full length cDNA of slti182, deginated GmASP1, is 1258 bp long and contains an open reading frame consisted of 326 amino acids. CmASP1 protein showed the highest identity (84%) with putative asparaginase from A. thaliana (AB012247), but it showed only 55% identity with another isoform of A. tathaliana (Z34884). The expression of GmASP1 during low temperature stress started to increase 3 hours after treatment, reached the maximum at 6 hour, and then decreased to the initial level at 48 hours. The amount of GmASP1 transcripts increased again when low-temperature-treated plants were transferred to room temperature, The present study suggests that GmASP1 may function to accelerate the protein synthesis which is important in the early response to low temperature.

This paper describes an e-Engineering framework to support collaborative design of automotive suspension systems developed at KIMM(Korea Institute of Machinery and Materials). The e-Engineering framework is proposed and developed on the base of the multi-layered software agents including engineering task agent which is generated from the domain knowledge of experts. The developed framework is aim to widely spread application to the small and medium enterprises by adopting open source technologies such as JADE (Java Agent Development Framework) and by using the independent characteristics related with applicant H/W and 81W system. This framework can provide an integrated design environment to support distributed personnel, design activities and engineering resources during product development process. For the validation of the system's applicability and efficiency, the several practical design processes for automotive suspension systems of RR/FR lower arms and RR cross member are applied and discussed. 본 논문에서는 한국기계연구원에서 개발된 자동차 서스펜션을 대상으로 한 협업설계 지원 엔지니어링 프레임워크 개발에 관하여 기술한다. 개발된 엔지니어링 프레임워크는 각 분야별 전문가 지식에 기초한 엔지니어링 task agent를 포함한 다양한 복수 계층의 소프트웨어 에이전트로 구성된다. 본 프레임워크는 폭 넓은 국내 중소제조기업 적용 확산을 목적으로 JADE(Java Agent Development Framework)와 같은 공개 소스 프로그램 기반으로 개발하였으며, 프레임워크의 확장성을 유지하기 위하여 관련 H/W 및 응용 S/W의 독립성을 가능한 한 유지하도록 노력하였다. 개발된 프레임워크는 제품개발과 정에 있어 지역적으로 분산된 사용자 및 엔지니어링 자원 등을 효과적으로 활용할 수 있는 통합된 협업 설계환경을 제공한다. RR/FR lower arm 및 RR cross member와 같은 몇 개의 실제 자동차 서스펜션 모듈의 설계엔지니어링 문제에의 적용을 통하여 본 시스템의 적용성과 효율성을 확인하였다.

Suppression subtractive hybridization (SSH)를 통해 상처에 의해 발현이 유도되는 cDNA들을 분리하였고, 그 중 하나인 gmwi33은 $\beta$-amyrin synthase 유전자들과 높은 유사성을 보였다. gmwi33의 전장 cDNA인 GmAMS1은 2416 bp 길이에 739개 아미노산으로 구성된 긴 open reading frame(ORF)를 포함하고 있었다. GmAMS1 단백질은 감초의 $\beta$-amyrin synthase인 GgbAS와 89%, 완두의 OSCPSY와 86%의 유사성을 보였다. 암조건 하에 5일간 기른 콩나물에서, GmAMS1는 빛을 쪼여주었을 때 가장 강하게 발현되었고 methyl jasmonate 처리와 저온처리 시에도 발현이 유도된 반면, UV-B나 elicitor를 처리하였을 때는 발현이 유도되지 않았다. 이러한 GmAMS1의 발현양상은 사포닌의 활성산소 제거기능과 밀접한 연관이 있을 것으로 추측된다. Suppression subtractive hybridization (SSH) was used to isolate wound-induced cDNAs from wounded soybean. One of wound-induced cDNA, gmwi33 showed high homology with genes encoding $\beta$-amyrin synthase. The full length cDNA of gmwi33, designated GmAMS1, is 2416 bp long and contains an open reading frame consisted of 739 amino acids. GmAMS1 protein showed 89% identity with licorice GgbAS1 and 86% identity with pea OSCPSY. In 5 day-old, dark-grown seedlings, the expression of GmAMS1 was most strongly induced by light and weakly induced by methyl jasmonate and by low temperature. However, GmAMS1 was not induced by elicitor or UV-B treatment. Such expression pattern might be closely related with the oxygen-radical scavenging activity of soyasaponin.

Obejectives : To investigate the clinical effect of electroacupuncture and bee venom acupuncture for benign prostatic hyperplasia(BPH) symptoms. Methods : Among 39 outpatients who were treated at a BPH clinic, 8 were finally selected for analysis by charts-review, retrospectively. They were treated by electroacupuncture and bee venom acupuncture more than 3 times. We estimated the effectiveness of the treatments by using the International Prostate Symptom Score (IPSS) questionnaire and checking their nocturia frequency. On the basis of these variables, we analyzed the statistical significations of symptom improvements. Results : Among 8 patients, the IPSS and nocturia frequency showed significant improvement after the final treatment compared with baseline (P = .0078, P = .0078). The IPSS significantly decreased even after the 1st treatment and also after the 2nd treatment compared with the baseline (P = .0078, P = .0078). The IPSS at post final-treatment, post 1st- and post 2nd treatment also showed significant improvement compared with IPSS at baseline in 6 severe symptomatic patients(P = .031, P = .031, P = .031). Nocturia frequency decreased after the 1st treatment compared with baseline and showed significant improvement between baseline and post 2nd treatment (P = .0078). Conclusions : In a retrospective and cross-sectional study investigating the clinical effects of electroacupuncture and bee venom acupuncture on BPH, these treatments proved to have significant therapeutic effects, particularly for various symptoms involving frequent nocturia.

Priapism is a persistent penile erection that continues for more than 4 hours beyond, or is unrelated to, sexual stimulation. Because priapism is a medical emergency, all patients with priapism should be evaluated and treated urgently. Subtypes of priapism are ischemic, non-ischemic and stuttering priapism. Stuttering type is a recurrent form of ischemic priapism in which unwanted painful erections occur repeatedly with intervening periods of detumescence. The etiology of this type is often idiopathic and the treatments are still not clearly established. We present one case of stuttering priapism which occurred after suppression of his sexual desire. A 23-year-old man visited our clinic complaining of recurrent pain and erections persisting for about 5 weeks. We performed evaluation and confirmed the diagnosis of Rigid swollen penis. Jibaekjihwang-tang gamibang (ZhiBaiDihuang-Tang Jiaweifang) was administerd to the patient for 9 days. After the treatment, duration of erections and pain showed remarkable improvements. This will be recorded as the first case report of treating priapism with a Korean medical approach and suggests that Korean medicine therapy can be efficient to treat priapism.
