우리나라 도로중 PMS가 구축된 도로는 현재, 고속도로와 국도가 있다. 그러나 많은 시(市)에서 도로의 효율적인 관리를 위해 요구되는 시도로 PMS는 아직 없는 실정이다. 따라서, 본 논문에서는 시단위에 적용가능한 Prototype PMS 전산시스템을 개발 제시하였다. 개발한 PMS는 기본적으로 PC 수준에서 운영 가능하도록 구성하였으며 GIS 기능을 이용하여 사용자가 쉽게 포장상태나 유지보수 현황 및 계획을 이해할 수 있게 하였다. 본 PMS의 기능상 구성은 크게 조회, 분석, 자료관리, 출력 부분으로 구축하였다. 특히, 분석과정의 주논리(보수우선순위결정, 보수공법결정)부분은 필요시 사용자가 각 항목의 criteria 값을 수정 할 수 있게 하여 시스템운영이 경직되지 않도록 배려하였다. PMS 데이터베이스의 항목은 시도로 PMS의 규모 및 목적을 고려하여 선정하였다. 또한 PMS에서 사용된 도로 관리길이 및 위치 지정체계는 노선을 기준으로 기본 100m길이의 section으로 분할관리하였으며, 위치 지정체계 방식은 reference points 방식을 기본으로 사용하였다.

현대의 의료용 방사선 발생장치는 영상을 저장하고 전송하기 위해 의료영상 표준규격으로 Digital image communications in medicine(DICOM)을 채택하고 있다. DICOM 규격에서는 피폭선량 정보 표시를 위해 DICOM dose Structured Report(DICOM dose SR)를 표준으로 제정하여 사용하고 있다. 이와 더불어 DICOM Modality Performed Procedure Step(DIOCM MPPS) 정보와 DICOM tag 정보에서도 부분적인 피폭선량 정보를 표시하고 있다. 본 연구에서는 DICOM과 관련된 피폭선량정보 표시방법에 대해 고찰하고 의료정보 시스템간의 상호연동 테스트를 위한 Integrating the Healthcare Enterprise(IHE)의 Radiation Exposure Monitoring(REM) 프로파일에 대해 살펴보았다. 의료기관에서 의료방사선피폭선량정보에 대한 품질관리를 위해서는 DICOM 정보에서 표시되는 피폭선량 정보형식에 대한 이해가 반드시 수반되어야 하고 장비도입 단계에서 관련 규격에 대한 검토가 이루어져야 한다.

The Tosyl-JM3 (TJM3) is a modified compound from one of 1,2,3,4-Tetra- hydroisoquinoline (THIQ) derivatives. The THIQs include potent cytotoxic agents that display a range of anti-tumor activities, antimicrobial activity, and other biological properties. In this study, we investigated the effect of TJM3 on the cytotoxicity, induction of apoptosis in human promyelocytic leukemia cells (HL-60 cells). TJM3 showed a significant cytotoxic activity in HL-60 cells (IC50 = approximately $60{\mu}g/m{\ell}$) after a 24 hr incubation. Treatment of HL-60 cells with TJM3 exhibited several features of apoptosis, including formation of DNA ladders in agarose gel electrophoresis, morphological changes of HL-60 cells with DAPI stain. Here we observed that TJM3 caused a decrease of procaspase-3 protein. Further molecular analysis demonstrated that TJM3 led to cleavage of poly(ADP-ribose) polymerase (PARP) by western blot and increase of hypodiploid (Sub-G1) population in the flow cytometric analysis. In conclusion, these above results indicate that TJM3 dramatically suppresses HL-60 cell growth and induces apoptosis. These data may support a possibility for the use of TJM3 in the prevention and treatment of leukemia.

The chloromethyl-2-dihydroxyphosphinyl-6,7-dimethoxy-1,2,3,4-tetrahydro- isoquinoline (CDDT) is a newly synthesized derivative from 1,2,3,4-Tetra- hydroisoquinoline (THIQ). The THIQs include potent cytotoxic agents that display a range of antitumor activities, antimicrobial activity, and other biological properties. In this study, we investigated the effect of CDDT on the cytotoxicity, induction of apoptosis in human promyelocytic leukemia cells (HL-60 cells). CDDT showed a significant cytotoxic activity in HL-60 cells ($IC_{50}$ = approximately $37\;{\mu}g/ml$) at a 24 hr incubation. Treatment of HL-60 cells with CDDT displayed several features of apoptosis, including formation of DNA ladders in agarose gel electrophoresis, morphological changes of HL-60 cells with DAPI stain. Here we observed that CDDT caused activation of caspase-3, caspase-8, and caspase-9. The most efficacious time on the activation of caspases-3 was achieved at 12 hr. Further molecular analysis demonstrated that CDDT led to cleavage of poly(ADP-ribose) polymerase (PARP), increase of hypodiploid (Sub-G1) population in the flow cytometric analysis. In conclusion, these above results indicate that CDDT dramatically suppresses HL-60 cell growth by activation of caspase-3 with caspase-8, -9 activity. These data may support a pivotal mechanism for the use of CDDT in the prevention and treatment of leukemia.

For the programming volume of PRAM, Ge2Sb2Te5(GST) thin films have been dominantly used and prepared by physical vapor deposition (PVD), chemical vapor deposition (CVD), atomic layer deposition (ALD). Among these methods, ALD is particularly considered as the most promising technique for the integration of PRAM because the ALD offers a superior conformality to PVD and CVD methods and a digital thickness control precisely to the atomic level since the film is deposited one atomic layer at a time. Meanwhile, although the IST has been already known as an optical data storage material, recently, it is known that the IST benefits multistate switching behavior, meaning that the IST-PRAM can be used for mutli-level coding, which is quite different and unique performance compared with the GST-PRAM. Therefore, it is necessary to investigate a possibility of the IST materials for the application of PRAM. So far there are many attempts to deposit the IST with MOCVD and PVD. However, it has not been reported that the IST can be deposited with the ALD method since the ALD reaction mechanism of metal organic precursors and the deposition parameters related with the ALD window are rarely known. Therefore, the main aim of this work is to demonstrate the ALD process for IST films with various precursors and the conformal filling of a nano size programming volume structure with the ALD?IST film for the integration. InSbTe (IST) thin films were deposited by ALD method with different precursors and deposition parameters and demonstrated conformal filling of the nano size programmable volume of cell structure for the integration of phase change random access memory (PRAM). The deposition rate and incubation time are 1.98 A/cycle and 25 cycle, respectively. The complete filling of nano size volume will be useful to fabricate the bottom contact type PRAM.

Recently, spintronic devices with submicron structures are widely investigated to take advantage of their unique micromagnetic properties. In this work, we study the temperature dependence of exchange bias in bilayer anti-dot arrays made by depositing Co (40 nm)/Ni (5 nm) ferromagnetic bilayer on Si substrate to form anti-dot arrays with a diameter $1{\mu}m$. The anti-dot patterning was done only for the upper Co layer, while the Ni underlayer was kept unperforated. The temperature dependences of magnetoresistance (MR) and exchange bias were studied along magnetic easy and hard axes. The in-plane MR measurements were performed using a physical-property measurement system (PPMS ; Quantum Design Inc.) at various temperatures. The standard in-line four-point probe configuration was used for the electrical contacts. As temperature was varied, the MR data were obtained in which in-plane field (H=3 kOe) was applied in the directions along the hard and the easy axes with respect to the lattice plane. The temperature dependences of magnetic anisotropy and exchange bias were also studied along the magnetic easy and hard axes. As temperature decreases, the single peak splits into two peaks. While no exchange bias was observed along the magnetic easy axis, the exchange bias field steadily increased with decreasing temperature along the magnetic hard axis. These results were interpreted in connection with the magnetic anisotropy and the effect of the anti-dots in pinning domain wall motion along the respective direction.

This study examines the characteristics of Paul Smith's fashion from the viewpoint of Habitus. To this end, on the theory of Bourdieu's Habitus concept and theory of the field, we derive the attributes of fashion and fashion designers and Habitus that appeared in fashion from the viewpoint of Habitus. Based on this, the tendency of Paul Smith's Habitus tendency has been examined and how it is expressed in fashion design and store production has been investigated. The scope of the study is from 1977 to the present, and it covers Paul Smith's menswear and stores. Research methods are literature research and visual data analysis. The results of the study are as follows. The characteristics of Habitus' tendency in Paul Smith are childlike imagination and humor, vigorous curiosity and observation, paranoid collection and memos, and British tradition and craftsmanship. Paul Smith's Habitus propensity reflects the following features in fashion design and store direction. First, a unique mix of wit or list structure, second, respect for uniqueness and discrimination with respect for the local image, and third, the new male image was presented to contribute to the diversification of consumers, and fourth, sensitivity and emotion reflecting his Habitus propensity. It is a friendly space for communication. As a result of analyzing and applying to Paul Smith, it was found that the special Habitus characteristics possessed by designers in fashion are important and impart a great influence.
