As home network is increasing to use, home network industry is developing too. Also, it is to be a popular subject in the network's topics. In this reasons, home network become a important thing because home gateway function is working between access network and home network. In the home network, it relates on the personal computer, home pad, and digital television. But, home gateway is not prepared standard point about techniques. Therefore, many kind of technique want to try for developing of home gateway's functions. Usually, we use ID/PASSWORD method in network control system. But, we found a lot of problems about classical network system while we experienced Jan/25 big trouble. We are considering about that home network system are using same network net. Therefore, seriously we have to check about security and safety at the home network's environment. This report focus on the home network's environment to control for using and efficiency and then it wants to find ways to protect from the internal and external attacks. Existing ID/PASSWORD method it used a electronic signature and the security against the approach from of external watch, the MIB structure of role base and the security of the Home network which leads the authority control which is safe even from the Home network inside it strengthened it used compared to it proposed.

Objective : This study was designed to investigate the relation between the angiotensin converting enzyme(ACE) gene polymorphism and Facial nerve palsy in the Korean population. Methods : This sudy was carried out on 117 Facial nerve palsy patients who were treated in the department of acupuncture & moxibustion, Hospital of Oriental medical college, Kyung-Hee University and 135 healthy control subjects. Blood samples from all subjects were obtaind for DNA extraction. The extracted DNA was amplified by polymerase chain reaction(PCR). PCR products were visualized by 2% agarose gel electrophoresis. Results : The sub-genotypes of ACE gene were II homozygotes, ID heterozygotes, DD homozygotes. While the distribution of ACE polymorphism in control subjects was 33%, 43%, 24%, the distribution of it in Facial nerve palsy patients was 32%, 50%, 18%(II, ID, DD). Thus, there was no significant different between the control and Facial nerve palsy groups. Conclusions : we conclude that there is no significant association between ACE gene polymorphism and Facial nerve palsy in Korean population. However, the findings of this study need to be confirmed in more patients and further studies. Additional epidemiologically based studies of the effects and relationship between ACE or other genes and lifestyles with regard to Facial nerve palsy is required.

Objective : This study was designed to investigate the relation between the angiotensin converting enzyme(ACE) gene polymorphism and stroke in the Korean population. Methods : This study was carried out on 58 stroke patients who were hospitalized in the department of acupuncture & moxibustion, college of Oriental Medicine, Kyung-Hee University and 61 healthy control subjects. Blood samples from all subjects were obtaind for DNA extration. The extracted DNA was amplified by polymerase chain reaction(PCR). PCR products were visualized by 2% agarose gel electrophoresis. Results : The sub-genotypes of ACE gene were II homozygotes, ID heterozygotes, DD homozygotes. While the distribution of ACE polymorphism in control subjects was 31%, 51%, 18%, the distribution of it in stoke patients was 33%, 52%, 16%(II, ID, DD). Thus, there was no significant different between the control and stroke groups. Conclusions : we conclude that there is no significant association between ACE gene polymorphism and storke in Korean papulation. However, the findings of this study need to be confirmed in large patients and further studies. Additional epidemiologicallly based studies of the effects and relationship between ACE or other genes and lifesyles with regard to stroke required.

One of celebrities using Social media caught public's eye and interest in Korea. Thereby the number of the user has grown rapidly and by last year it had reached to about 770 million. But at the same time, it has brought us social issues such as invasion of privacy, spreading of malicious code, and stealing of ID. To solve these problems, first the government need to establish adequate law and policy. Second, Service provider should remove vulnerability in the security system and filter illegal information. Third, individual user should put more effort to protect their own privacy. This paper will suggest a solution of using the Social media more sound and secure.

This case report describes the orthodontic treatment performed for open bite caused by internal derangement (ID) and osteoarthritis (OA) of the temporomandibular joint (TMJ). A Japanese woman, aged 31 years and 11 months, referred to our department by an oral surgeon had an open bite with clockwise rotation of the mandible and degeneration of the condyle. The overbite was corrected through intrusion of the maxillary and mandibular molars using mini-screw implants to induce counterclockwise rotation of the mandible. Then, the mandibular second premolars were extracted and comprehensive orthodontic treatment was performed to establish a Class I molar relationship with distalization of the maxillary arch and to eliminate anterior crowding. Following treatment, her facial profile improved and a functional and stable occlusion was achieved without recurrence of the TMJ symptoms. These results suggest that orthodontic intrusion of the molars is one of the safer and less stressful alternatives for the management of open bite due to degeneration of the condyles caused by ID and OA of TMJ.

JPMP SID Tag is the security senor tag to provides physical information protective function using sensor module, has impossible feature to copy and fake the data which is stored in the tag. So data which is stored in the JPMP SID Tag has authenticity, integrity, originality. Therefore JPMP SID Tag could be applied in the place where the security of data is demanded. This paper propose the system using the JPMP SID Tag to acquire and protect digital evidence where cause investigation of accident is necessary. Also, proposed systems is complement of software security with composition secondary control logic for JPMP SID tag access control.

Each online user should perform a separate registration and manage his ID and password for each online commerce or SNS service. Since a common secret is shared between the user and the SNS server, the server compromise induces the user privacy breach and financial loss. In this paper, it is considered that the user's authentication material is shared between multiple SNS servers for user authentication. A blockchain service architecture based on Hyperledger Fabric is proposed for each user to utilize an identical ID and OTP using the enhanced hash-chain-based OTP.

Sasang Constitutional Medicine is a major branch of Korean Traditional Medicine. The differences of disease susceptibility to be shown in Sasang constitution may be due to genetic factors. Therefore, I examined interrelationship among cerebral infarction (CI), apolipoprotein E (apo E) gene polymorphism, and Sasang constitutional classification. Apo E is a key protein modulating the highly atherogenic apoB containing lipoproteins and is a candidate gene for the development of coronary artery disease (CAD). The ε2 and/or ε4 alleles were the first to be implicated in premature CAD, which resulted in this polymorphism being extensively studied. I investigated the association between apo E genotype and CI by case-control study in a Korean population. I also classified CI patients and control group into groups according to Sasang Constitutional Medicine. 218 CI patients and 379 controls without CI were examined. Apo E genotype was determined by 8% polyacrylamide gel separation after DNA amplification. A frequency of apo E ε3/ε3 in the apo E genotype distribution was higher in the CI patients compared with that in controls. Also, it was widely known that Taeumin was easily attacked with CI, but there was no association between apo E polymorphim and Taeumin. However, the Taeumin constitution did not enhance the relative risk for CI in the subjects with apo E ε2 and/or ε4 alleles. No differences in the apo E genotypes frequencies were observed in the Taeumin compared with that in the other constitutions. In addition, I investigated whether the DD(deletion/deletion) or ID(insertion/deletion) genotype of angiotensin converting enzyme (ACE) gene, a candidate gene for CI, was associated with CI, Taeumin constitution, and apo E polymorphism. As a result, the frequency of Taeumin constitution was significantly higher in CI patients with both apo E ε3/ε4 and ACE ID/DD genotypes than in the remaining Sasang constitutions. In summary, it was concluded that the apo E polymorphism is a major risk factor for CI in Koreans and the ACE ID/DD genotype enhanced the relative risk for CI in the subjects with apo E ε3/ε4 genotype and Taeumin constitution.
