The police is huge career civil service organization. In 1999, police organization employed 7,801 persons as a new hiring. The police had revised employment system several times for competent human resources. But, it is true that much improvements need yet for person's employment which equip eligibility. Specially, discussions need for many new hirings by duty police system abrogation. Career civil service system is impossible of dismissal after permanent appointment. It is true that competitive rate of police officer examination much rose. But it's not important about organization development in addition this unconnects with competent resources. Must change police officer employment system for organization's future development. This study proposed policy about improvement way of examination for service step, field training officer and appointment.

The IT education is the element which is important from information anger society which is changing quickly to be self-explanatory and the talented men who will work from IT field educates the role of the college agency for is becoming larger. But information - computer subject are not regular academic work still from the secondary school and the disciple of teacher appointment the teacher positivity from the now college of education which is coming to be narrow little by lit시e must dispose positive and spontaneously. Becomes the hazard IT powerful country which will reach and our country computer education for analysis it tries the appointment humble refusal for the curriculum and a computer teacher positivity of the hazard college of education and it analyzes, the reporter to propose field must be improved it.

본 연구는 장애인생활시설에서의 정보화에 대한 고찰이다. 정규 시각장애인학교와 장애인생활시설의 시각장애인 교육환경의 비교하기 위하여 대전의 한 장애인생활시설을 선정하고. 장애인생활시설에 몸담고 있는 원생의 유형별, 연령별 인원현황, 연령별 교사현황, 컴퓨터 보유현황, 원생의 주간교육 일정, 시각장애인용 기자재 보유현황 등을 조사하였다. 그 결과 시각장애자에게 있어서 정보화의 기초가 되는 점자 숙지자가 많지 않아 점자교육의 확대가 필요하였고, 정규학교와 달리 컴퓨터교육에 필요한 기자재가 턱없이 부족하여 학습의 환경조성이 시급한 상황이었다. 또한, 교사 중 일부만이 사회복지나 특수교육을 전공하였고, 컴퓨터를 전공한 사람은 단 한 명도 없었다. 그 이유는 아직 장애인 생활시설의 교사채용기준은 법으로 규정되어 있지 않고 생활시설의 교사에 대한 처우가 일반학교의 교사에 대한 처우에 못 미치는 상황이어서 전공자의 임용지원이 많지 않기 때문이었다. 장애인 생활시설에서 정보화 촉진을 위해 정부의 지원을 바탕으로 한 기자재의 확충과 꾸준한 교육연수를 통한 전문지식인의 양성과 그에 걸 맞는 물리적, 사회적 대우를 통하여 원생들에게 질 높은 교육환경을 제공하는 것이 시급한 것으로 조사되었다.

For the polynomial spline regression with fixed knots, some properties of the D-optimal design are discussed. Also the D-optimal design for some cases are found analytically by using a normalized B-spline basis for $S(P_m : k : \Delta)$. Based on the Kiefer-Wolfowitz equivalence theorem, the D-optimal design for some cases are found by numerical methods.

This study examined the effects of neoliberal educational policy on the appointment system of teachers to assess the impacts of this neoliberal education policy. Neoliberal education policy has led to increased private education cost, and strengthened the function of social stratum reproduction in the education system despite increasing the efficiency and flexibility. Since contracted employment was applied to the educational field, the number of regular teachers began to decrease, while that of contracted teachers increased. For example, the number of contracted teachers was 300 in the 1990, which increased to 42,042 in 2015. Neoliberal education policy contributed to teacher's quantitative demand; however, the increase in the number of contracted teachers is ultimately degrading the education quality. In an education market, the issues of balancing between supply and demand often occur. Therefore, it is necessary to strongly control the number of contracted teachers by limiting their contract period. Furthermore, an institutional device that can convert a contracted teacher to a regular one must be established.

Watermarking is one of the methods that insist on a copyright as it append digital signals in digital informations like still image, video, ets. This paper proposed a novel digital watermarking scheme which combines a QR code and a watermarking method using DCT coefficient. It proposed an algorithm for selecting a QR code from a image and to be converted into a watermark. It processed a watermarking process using expanded watermarking method in DCT area. This simulation results showed that the PSNR difference between the proposed scheme and the original image was 33.98dB and the normalized correlation between the proposed scheme and the original image was above 99.51. The proposed method is reusable.

The purpose of the present study was to examine the effect of diesel exhaust particles on human aortic vascular smooth muscle cells (VSMCs). DNA synthesis, cell viability and morphology of VSMCs after treatment of diesel exhaust particles (DEP) and fine particulate matter (PM$_{2.5}$) were assayed. PM$_{2.5}$ inhibited the DNA synthesis of VSMCs in a concentration -dependent manner, whereat DEP did not affect VSMCs up to 50$\mu\textrm{g}$/mL. These results were confirmed by morphological examination of VSMCs. PM$_{2.5}$ showed a dose-dependent cytotoxicity of VSMCs by MTT assay. Fraction 4 (organic acids) and fraction 8 (moderately polar compounds) showed the most potent inhibition of DNA synthesis of VSMCs, and fraction 7 (slightly polar compounds), fraction 9 (higher polar compounds), and fraction 6 (aromatic compounds) were next order. These results were confirmed by morphological examination of VSMCs. These results suggest that PM$_{2.5}$ inhibits the DNA synthesis of VSMCs through the cytotoxicity.oxicity.

Watermarking is one of the methods that insist on a copyright as it append digital signals in digital informations.(image, video, ets) In this paper, we proposed a digital watermarking algorithm which improved Gradient of DCT Coefficient. This method targets MPEG-2 TM5 system and watermarking process is to be performed during Quantization DCT. Watermark was inserted on Y components of each frames. The PSNR difference between the compressed images with and without watermarking was only 0..23dB. In each case that the resulting image was reusable the normalized correlation between the extracted watermark and the original one was above 0.99.
