산업안보위협은 개인 또는 전·현직자의 이익을 위해 다양한 경로를 통해 지속적으로 산업기술들을 유출하였지만, 최근에 는 국가에서 지원하는 사이버 공격자 그룹을 활용하여 신기술을 탈취하려는 목적의 사이버공격을 감행하고 있어 현재 산업체뿐만 아니라, 국가경제의 손실이 매우 크다. 따라서 본 논문에서는 정보탈취를 목적으로 하는 국가 배후 해킹조직의 침투 경로 및 공격 단계와 국가핵심기술 유출 사례와 연계하여 MITRE사(社) ATT&CK 프레임워크를 활용하여 산업기술위협에 대응할 수 있는 기술을 소개 한다.

We had applied Saenggangunbitang, Gamijihwangtang, and Saenggangunbitang-Gamijihwangtang on a alcoholic liver disease patient with diabetes mellitus, Saenggangunbitang has been used to treat alcoholic liver disease and had known to have beneficial effects. Gamijihwangtang has been used to treat Yin deficiency syndrome in Orient Medicine. We observed clinical symptom, liver function, nutritional state and blood sugar. After first administration, Clinical symptom and blood sugar were improved by Gamijihwangtang medication. Alter second administration, Clinical symptom, blood sugar and liver function were improved by Saenggangunbitang-Gamijihwangtang medication. After third administration, clinical symptom and liver function were improved by Saenggangunbitang medication. It is possibly suggested that Saenggangunbitang-Gamijihwangtang medication has a therapeutic effect on alcoholic liver disease with diabetes mellitus.

During the Period from 22th to November 26th, 1971, An Epidemiological Survey was performed on the Accident which was occurred by Leakage of Chloride Gases in A Chemical Industry, one of Wul San Industrial Areas. The obtained results were as follows; 1. The largest damage was observed at Yeo Cheon Dong, 5.38 Km2 in Area and 8,192 in the Residents. 2. By the age distribution of Yeo Cheon Dong, The largest damaged area resulting from chloride accident, the age group of between 10 and 39 was highly occupied with 55.2% Of all Yeo Cheon residents. 3. The number of patient was 436 totally, 198 in male and 238 in female. 4. By the age group distribution of the patient, in case of male, the largest group was under 20 age (96) and female, between 20 and 40 age group. 5. By the educational level of the patient, No-Education group was 116 (26.6%), and primary school, middle school and high school were respectively 168 (38.5%), 68 (15.6%) and 12 (2.8%). 6. By the occupational distribution of the patient, No-Occupation group was 49.7%, students and agriculture were respectively 14.4% and 8.1%. 7. By the complaints of the patient, most of all were for respiratory tract, those are coughing (56.9%), chest tightness (35.6%), sore throat (24.8%), and so forth. 8. By the injured domestic animal, the Dog was most highly injured with 46.2%.

In this paper, we propose a new fault tolerant architecture for high availability systems, where for module internal operations both processor modules perform the same tasks at the same time independently of each other while for module external operations both processor modules act actively. That is, operations of synchronization between dual processor modules except clock synchronization are requested only when module external operations are executed. The architecture can not only improve system availability by reducing system reintegration time but also reduce performance degradation problem due to frequent synchronization between dual processor modules. The clock unit consists of a clock generator and a clock synchronization circuit. This supplies a stable clock signal under clock unit disorder of any processor module or rapid clock signal variation. And this architecture achieves system availability and data credibility by designing as symmetrical form.

A major feature of type 1 diabetes mellitus (T1DM) is hyperglycemia and dysfunction of pancreatic ${\beta}$-cells. In a previous study, we have shown that Tat-DJ-1 protein inhibits pancreatic RINm5F ${\beta}$-cell death caused by oxidative stress. In this study, we examined effects of Tat-DJ-1 protein on streptozotocin (STZ)-induced diabetic mice. Wild type (WT) Tat-DJ-1 protein transduced into pancreas where it markedly inhibited pancreatic ${\beta}$-cell destruction and regulated levels of serum parameters including insulin, alkaline phosphatase (ALP), and free fatty acid (FFA) secretion. In addition, transduced WT Tat-DJ-1 protein significantly inhibited the activation of $NF-{\kappa}B$ and MAPK (ERK and p38) expression as well as expression of COX-2 and iNOS in STZ exposed pancreas. In contrast, treatment with C106A mutant Tat-DJ-1 protein showed no protective effects. Collectively, our results indicate that WT Tat-DJ-1 protein can significantly ameliorate pancreatic tissues in STZ-induced diabetes in mice.

Objective : It is well known that Gagamsojeokbackchool-san show antitumor effects and its activities are result from enhancement of immune function, we investigated the antitumor effects of Sambonggangyongbaneo-tang and its mechanism. Methods : We measured change of body weight, weight of immune organs (Spleen, Thymus), Liver, Kidney, tumor weight, cytotoxicity for investigation of antitumor effects of Sambonggangyongbaneo-tang. Results : 1. The body weight of mouse has no significant difference between control and sample groups. 2. The weights of immune organs (Spleen and Thymus) decreased significantly in sample groups. The weights of Liver and Kidney have no significant difference. 3. The tumor weights in mouse decreased significantly in sample groups and showed dose-dependent effect. 4. Cell viability of Sarcoma 180 has no significant difference in sample groups. 5. HeLa cell viability has no significant difference in low concentration, but it decreased significantly in high concentration. Conclusions : According to the above results, it could be suggested that Sambonggangyongbaneo-tang has prominant antitumor effects and cytotoxicity.

Objectives : This study was prepared for investigating the clinical features of stroke patients. Methods : We retrospectively reviewed the medical records of 102 patients who were admitted to Department of Internal Medicine, College of Oriental Medicine, Kyung-Won University with a diagnosis of stroke from Jan. 1, 2004 to Dec. 31, 2004. Results : Ischemic stroke(include TIA, 82.4%) was more common than hemorrhagic stroke(17.6%). The incidence in male was 41.2%, in female was 17.6% and the most prevalent age group is over-sixties. Cerebral infarction was most frequently noticed in lacunar-infarction and hemorrhage in putamen. Hypertention, the most preceding diseases, followed by diabetes mellitus and CVA. The rate of recurrence was 27.45%. Cerebral infarction and cerebral hemorrhage was much occurred after rising. The most patients visited the hospital within 24 Hours. The most common symptoms in admission time were motor weakness and speech disorder. The complication was mostly mental disorder. Conclusion : Our study on CVA patients was similar to previous studies from 1994 to 2003. In most cases, western and oriental treatment and medicine were given synthetically.

Recently, business application vendors have responded to customer demand with several technological and organizational changes for reflecting network-oriented process flow with electronic communication and expanding their market. In organizational changes. Vendors are adding new functionality to their core offerings through mergers and acquisitions, or by partnering with front-office operation and SCM vendors. And technological changes are embracing the development of component-based application and middleware technology to be possible with integration of their function modules. We will present the design and development process of component-based SCM system to be integrated with heterogeneous ERP under implementation. Especially, we survey and analyze the technology related with CBD(Component-Based Development) to be adapted this research - component's design and methodology, the interface for component integration, middleware's development methodology of Enterprise Middleware vendo to bundle various types of middleware into a single package product with easy-to-use interface.
