Definition of Security Practices in STP for SLMM

Tai-Hoon Kim 보안공학연구지원센터 2008 International Journal of Hybrid Information Techno Vol.1 No.1

To manage security level of information system (IS), organizations must select security practices (SP) first, and then apply them according to security level. SP can be divided into 2 groups security management part (SMP) and security technology part (STP), and some SPs in SMP were proposed already by Drs. Tai-hoon Kim and Kouichi Sakurai [1]. In this paper, we propose some SPs in STP to construct STP for Security Level Management Model (SLMM).

OS Security Enhancement System by Considering Security Level

Tai-Hoon Kim,Gil-cheol Park,Seok-soo Kim 보안공학연구지원센터 2007 International Journal of Multimedia and Ubiquitous Vol.2 No.3

Trusted operating systems (OS) provide the basic security mechanisms and services that allow a computer system to protect, distinguish, and separate classified data. Trusted operating systems have been developed since the early 1980s and began to receive National Security Agency (NSA) evaluation in 1984. The researches about trusted OS are proceeding over the world, and new product type using the loadable security kernel module (LSKM) or dynamic link library (DLL) is being developed. Most important concept in this paper is Security Level proposed by Dr. Tai-hoon Kim, because this concept should be considered in every operational environment. This paper assumed security level 1st proposed by Dr. Taihoon Kim, and proposes a special type of product using LSKM and specific conditions for operational environment should be.

時調의 形態的 淵源考

李泰極 이화여자대학교 한국문화연구원 1974 韓國文化硏究院 論叢 Vol.24 No.-

There were divided opinions as to the origin of Sijo among Korean scholars and writers. On one hand Ann Ja San and Jeong Nai Tong insisted that the origin was from Chinese poetry. Kim Tai Joon, Lee Kwang Soo, and Jo Yoon Jai mentioned that Sijo might have been formulated lated either naturally since ancient times or under the influences of Hang Ka, Silla poetry. On the other hand, Lee Pyeong Ki insisted that Sijo formed from the traditional six-phrase and three-verese form of the folk-song style, and Lee Heui Seung referred to origin from ritual songs by Shaman. Lee Tak, also insisted that the three-phrase and sixverse form of Hyang ka corresponds to the three-line form of Sijo. For this and other reasons. Sijo might be drawn from the three-vers form of Hyang Ka. The above divided opinions are commonly meaningful ones that seek. The origin from the format aspect. However, it is hard to find traditional format from the six-phrase and three-verse form of folk-song. The three-line and six-phrase format of Shaman's ritual songs rather influenced format form Sijo format. Based on the above points of view, we can find possibilities about the origin of Sijo format from the Hyang Ka format. When we compare three-lines of Sijo format with three-phrases pf Hyang Ka format, it is possible to find corresponding features between the two formats. We are uncertain about the origination of Sojo's six-phrase format. We can prove Sijo's six-phrase format in the existing works of Hyang Ka particularly the first eight phrases on the ten-phrases which are linked with two phrases of Sijo's pre-and mid-lines. Another two phrases which are linked with one-phrase are identified with metalines of Sijo. On the other hand, the first eight phrases of the Hyang Ka format have a contextual linkage with the four-phrase units. These two units correspond to Sijo's pre-and mid-lines, and phrases units of the ninth and tenth phrases correspond to the Sijo's meta-lines. Under these circumstances, the three-line and six-phrase format of Sijo resulted from the ten-phrase format of Hyang Ka, then this format generated into the Pyeol Kok format, and finally Pyeol Kok format divided into present Sijo format.

cis-Dichlorodiammineplatinum (Ⅱ)이 Hamster 신장의 Acid Phosphatase 활성에 미치는 영향

백태경,정수태,이규식 한양대학교 의과대학 1987 한양의대 학술지 Vol.7 No.2

cis-Dichlorodiammineplatium (II) (cis-DDP), a metallic compound, is a bifunctional alkylating agent that has been known as an effective anticancer drug. It is so effective on solid tumor that it has been used in the therapy of ovarian tumor, epithelial tumor of the neck, bladder cancer and thyroid cancer. Since cis-DDP reacts with DNA and RNA especially with guanine base, the protein synthesis is inhibited consequently. As a result, administration of cis-DDP results in cytotoxicity of the renal epithelial cell. So te author undertook the present study to pursue the effect of cis-DDP on the activity of acid phosphatase of the hamster kidney. Hamsters, weighing 110gm, were used as experimental animals. The experimental animals were killed at 2, 4, and 6 days after administration of 6 mg/kg of cis-DDP. The specimens obtained from the kidney were sectioned at 16㎛ thickness with frozen cytostat. The acid phosphatase activity was observed by the Gomori's method for the histochemical study. The results were as follows. 1. The acid phospatase activity was moderate positive at the cortical glomeruli and weak positive at the outer stripes of the medulla in the 2 day cis-DDP treated group. 2. The acid phosphatase activity was moderate positive at the pars concoluta glomeruli of the cortex and other strips of the medulla while a weak positive activity was seen at the inner stripes of the medulla in the 4 day cis-DDP treated group. 3. The acid phosphatase activity was moderate at the parts convoluta and renal medulla, and strong positive activity was seen at the glomeruli in the 6 day cis-DDP treated group. It is suggested that cis-DDP decreases the acid phosphatase activities of the hamster kidney.

김태규,이혜정,정서영,정태준,한훈 대한조혈모세포이식학회 1997 대한조혈모세포이식학회지 Vol.2 No.1

연구배경: HLA-DP 유전자는 DR 및 DQ와 같이 항원제공 세포(APCs), B 세포 및 활성화된 T 세포등의 표면에 발현되는 class Ⅱ 유전자로서 외인성 항원제공시 MHC 제한(restriction)과정을 통해 면역 반응에 관여한다. DP 항원 분자는 PLT(primed lymphocyte test)와 같은 세포학적 방법에 의해 처음으로 규명되었고, 이어서 혈청학적 형별이 시도되었으나, DR, DQ 분자에 비해 발현 정도가 낮아 형별에 어려움이 있었다. 최근 DP 유전자의 염기서열이 밝혀짐에 따라 DNA 수준에서 DP 형별이 가능하게 되었으며, 지금까지 DPA1 10개, DPBI 77개의 대립유전자가 밝혀졌다. 본 연구는 이식의 결과 및 질병 발생과 연관이 있다고 추정되는 HLA-DPB1 대립유전자를 DNA 수준에서 형별하고 정상 한국인의 DP 대립유전자 분포를 확인하기 위해 시도되었다. 방법: HLA-DPB1 유전자 중 초가변부위(hypervari-able region)가 있는 exon 2 부위를 일차적으로 증폭시킨후, 17종의 probe를 사용하여 PCR-SSOP를 실시하였고, PCR-SSP에는 5종의 primer를 사용하였다. 이들 방법은 DP형이 알려진 미국 UCLA 대학의 international cell exchange sample 88개를 표준 DNA 시료로 이용하여 확립하였다. 결과: 36종류의 HLA-DPBI 대립유전자를 형별할수 있음을 확인하였다. 그러나 DPBI*0402와 0601 대립유전자를 동시에 갖는 heterozygote인 경우에는 DPBI*0201와 2001을 동시에 갖는 heterozygous와 구분이 어려웠다. 100명의 정상 한국인에서 DPBI 대립 유전자형의 분포를 조사한 결과 한국인에서는 11종류의 HLA-DP 대립유전자가 존재함을 확인하였고, DPBI*0501(36.5%), 0201(27%), 0402(10.5%) 대립유전자의 순으로 분포되어 있었으며 검출율은 100%였다. 결론: 이상의결과로 골수 이식 등 이식시 공여자와 수혜자간의 조직적합성은 HLA-DP, DQ뿐만 아니라 DP도 확인 하게되었으며, 앞으로 질병과의 연관성 연구에서 이용될수 있을것으로 사료된다. Background: The HLA-DP genes are highly polymorphic, which encode heterodimeric cell surface glycoproteins that play a role in the immune response as restriction elements in antigen presentation. HLA-DP antigens were initially defined through the primed lymphocyte test (PLT), and the serological typing has been performed which is practically difficult because the expression of DP molecules is very low, comparing with that of DR and DQ. Recently, DNA sequencing and PCR have allowed the various and extensive study on the HLA-DP genes. We developed the molecular typing method for HLA-DPBI alleles, and studied the distribution in normal Korean population. Methods: After PCR amplification of hypervariable exon 2 regions in HLA-DPBI gene, both PCR-SSOP (sequence specific oligonucleotide probes) with 17 probes and PCR-SSP (sequence specific primers) by 5 Primers were used. And this method was tested using a international pannel DNA as standard. Results: Total 36 alleles of HLA-DPBI were defined in the standard DNA pannel. However, DPBI*0.402, and 0601 heterozygote could not be distinguished from DPBI*0201 and 2001 heterozygote. And 11 alleles were defined in 100 normal Koreans and the common alleles were DPBI*0501 (36.5%). 0201 (27%) and 0402 (10.5%). The detection rate was 100% in this study. Conclusion: As the results, the molecular typing of HLA-DPBI alleles is possible for the accurate matching between donor and recipient in born marrow transplantation and for the study of disease association.

류필열,정문태,신부안,정선식,안태휴 대한화학요법학회 1990 대한화학요법학회지 Vol.8 No.2

Antimicrobial activities of nalidixic acid(NA),norfloxacin(NX), oxolinic acid(OA), pefloxacin(PX), pipemidic acid(PA), oxacillin, cefotaxime(CFT), cephaloridine, cefazoline, moxalactam(MX), gentamicin, amikacin(AK) and rifampin(RP) were compared by the agar dilution method against 31 strains of K. pneumoniae isolated from various clinical spectimens. And then combined activities of RP with each of the quinolones (NA, MX, OAA, PX, and PA) against the test strains were measured by checkerboard dilution and time-killing methods. The growth inhibitory activities of PX, NX, OA, MX and AK were exellent, and those of PA, NA, RP and CFT were moderate, while the other's being almost negligible. The bactericidal activity of PX was more active than that of the other quinolones. Increasing concentrations of the quinolones resulted in a parallel increment of killing rate. However, when levels of quinolones were excessive beyond the most effective bactericidal ones, the bactericidal activity was decreased. In the combined growth inhigitory tests of RP with quinolones by checkerboard agar dilution method, synergistic and additive effects were rarely observed, and antagonism was noticed among the combinations in the following order: RP-NA, 22 strains (71%); RP-PA, 21 strains (67.7%); RP-OA, 17 strains (54.8%); RP-PX, 15 strains (48.4%) and RP-NA, 14 strains (45.2%). In the combined bactericidal tests measured by time-killing method, RP was found to reduce the activities of all five quinolones tested. And the gradual increasing of RP dose was revealed to reduce progressively the bactericidal action of the quinolones. But when RP was added to quinolones after 1 hour of incubations, the bactericidal activities were not affected.

근대문학작품의 도시풍경구도에 나타난 시·공간의 체험적 인식에 관한 연구 : 소설 "소설가 구보씨의 일일"을 중심으로 Focused on the novel entitled "a novelist Gubo's day"

김기범,김태영 淸州大學校 都市·地域開發硏究所 2000 都市·地域開發硏究 Vol.8 No.2

The purpose of this study aims to understanding a common mental image between architecture and literature work in the modem ages, and especially the experiential recognition of time·space described on townscape. Following the result, Kyong-song have been represented to compound emotion with modem architecture established in 1930s of Modem Ages. First of all, the experiential recognition have been connected to the conflict structure between past and present townscape in the novel entitled "a novelist Gubo's day" by Park Tai-Won. And so on, such townscape consciousness was one of the immediate causes of the reminiscence.

POS System Design in Security Level 1st

Seok-soo Kim,Tai-hoon Kim 보안공학연구지원센터 2007 International Journal of Multimedia and Ubiquitous Vol.2 No.2

POS system is a supply net administration system for customer management. It becomes an essential element in distribution industry to construct database, and uses XML-Encryption to complement PKI techniques and standards for security. POS system has four advantages. First, it does not have to be certificated and transmit data every time because there is no server. Second, it can integrate database by using XML and improve portability of program itself. Third, transmitted data is safe because of XML-Encryption. Fourth, processing speed will be faster because it gathers data from data transmission. All systems should be designed by considering security level to reduce non-necessary burdens. The concept of security level management was developed by Dr. Tai-hoon Kim a few months ago, and this paper used this idea. In this paper, Security Level 1st environment was considered to design POS systems.
