경기도의 연합정치 성과에 대한 분석을 실시함에 있어 정책연합, 정부연합이라는 두 가 지 분류기준을 주요변수로 규정하였다. 아울러, 경기도 연합정치를 평가함에 있어 한국과 같은 지방자치단체의 독임제 기관구성 하에 연합정치의 성과를 분석하여 연합정치의 활성 화를 위한 방안으로서 지방자치제도 개선방안을 제시하였다. 경기도 연합정치의 한계로 행정업무 지연의 문제 등 연합정치로 인한 다양한 사업으로 인해 많은 예산이 반영되고 해당 부서의 중요사업에 대한 검토를 신속하게 이루어져야 함 에도 불구하고, 보고 및 결제단계 증가로 시간소요 또한 증가하는 등의 문제점이 나타났다. 향후 경기도 연합정치를 활성화시키고 나아가 이를 실천하기 위한 지방자치제도의 개선 방안으로 첫째, 기관구성의 다양화이다. 둘째, 지방장관제 도입이다. 셋째, 광역시도 의회의 역량을 강화하는 것이다. 넷째, 지방선거제도의 개편이다. On the other hand, comparing the first and second periods in terms of the governmental coalition, the allocation of power and the improvement of the coalition process can be mentioned. First, from the aspect of power allocation, the first stage handed over to the opposition party the vice governor of social integration, which is responsible for the three countries of health, welfare, environment, and women's family. In the second stage(Cho Sung-Ho et al., 2017), In this way, the opposition party is able to share power with the opposition party. At the same time, it introduced the coalition chairperson system, which further strengthened the power of political parties participating in the coalition. In addition, by establishing a unified political arbitration committee to facilitate the conflict situation that occurred under the coalition government, the coalition government made soft landing. In the future, we will suggest ways to improve the local autonomy system to revitalize the Gyeonggido coalition politics and to practice it. First, diversification of organization. Second, the introduction of local ministers. Third, the metropolitan city should strengthen its capacity. Fourth, it is a reorganization of local electoral system.

조미애,민성란,고석민,유장렬,이준행,최필선,Cho, Mi-Ae,Min, Sung-Ran,Ko, Suck-Min,Liu, Jang-Ryol,Lee, Jun-Haeng,Choi, Pil-Son 한국식물생명공학회 2006 식물생명공학회지 Vol.33 No.4
정상' 배추와 '서울' 배추의 배축절편을 선발마커로서 hygromycin 저항성유전자를 갖고 있는 pCAMBIA1301와 paromomycin저항성유전자를 갖고 있는 pPTN290으로 각각 형질 전환된 LBA4404 또는 EHA101균주와 공동배양한 후 선발배지에서 배양하면서 형질전환체를 선발하였다. 형질전환빈도는 사용된 항생제와 품종에 따라서 현저하게 차이가 있었으며, 특히 paromomycin은 hygromycin보다 효과적이었고 정상 배추는 서울배추보다 양호하였다. 가장 높은 형질전환빈도는 (0.70%) 100mg/L paromomycin이 첨가된 선발배지에서 정상배추의배축을 배양할 경우 얻어졌다. GUS양성반응으로 확인 한 결과 정상배추에서 9개체와 서울배추에서 3개체를 각각 얻었으며, 온실에서 생장한 후 $T_1$종자를 수확하였다. $T_1$ 종자를 다시 발아시켜 유식물체를 얻은 후 GUS양성반응을 확인함으로서 외래유전자가 안정적으로 발현하고 있음을 확인하였다. Hypocotyl explants of Chinese cabbage (us. 'Jeong Sang' and 'Seoul') produced adventitious shoots on Murashige and Skoog (MS) basal medium supplemented with 4mg/L $AgNO_3$, 5 mg/L acetosyringone, 4 mg/L 6-benzyladenine and 3mg/L alpha-naphthaleneacetic acid (SI) after cocoultivation with strains of Agrobacterium tumefaciens (LBA4404) harboring the pCAMBIA1301 and the $_PPTN290$ containing hygromycin-resistance gene and paromomycin-resistance gene as a selectable marker genes, respectively. There was a significant difference in the frequency of transgenic plants depending on antibiotics and cultivars used. Paromomycin was better than hygromycin, and cultivar 'Jeong-sang' was higher than 'c.v. Seoul' in the frequency of transgenic plants. In particular, the highest frequency (0.70%) of transgenic plants was obtained from selection medium (SI) containing 100mg/L paromomycin in c.v., 'Jeong-sang' GUS positive response were obtained 9 plants and 3 plants from the cultivars, 'Jeong-sang' and 'Seoul', respectively. They were grown to maturity in a greenhouse and normally produced $T_1$ seeds. GUS histochemical assay for progeny $(T_1)$ revealed that the transgenes were expressed in the plant genome.

In the present study, the structural response of breakwaters installed on container carriers against green water impact loads was numerically investigated on the basis of the fluid-structure interaction analysis. A series of numerical studies is carried out to induce breakwater collapse under such conditions, whereby a widely accepted fluid-structure interaction analysis technique is adopted to realistically consider the phenomenon of green water impact loads. In addition, the structural behaviour of these breakwaters under green water impact loads is investigated simultaneously throughout the transient analysis. A verification study of the numerical results is performed using data from actual collapse incidents of breakwaters on container carriers. On the basis of the results of a series of numerical analyses, the pressure distribution of green water was accurately predicted with respect to wave mass and velocity. It is expected that the proposed analytical methodology and predicted pressure distribution could be used as a practical guideline for the design of breakwaters on container carriers.

keV-neutron capture gamma-ray spectrum of $^{197}Au$(natural gold) sample have been measured in neutron energy range from 10 to 90 keV using the 3-MV pelletron accelerator of the Research Laboratory for Nuclear Reactors at the Tokyo Institute of Technology. Pulsed keV neutrons were produced from the $^7Li(p,n)^7Be$ reaction by bombarding on the $^7Li$ target with the 1.5-ns bunched proton beam. The incident neutron spectrum on the Au sample was measured by a $^6Li$-glass scintillation detector and TOF method. Capture gamma-rays from Au sample were measured by anti-Compton NaI(TI) spectrometer. Five average neutron energy regions were selected to obtain the neutron capture spectrum. Several gamma-ray peaks in the spectrum were found in the present experiment. 동경공업대학교의 3MV 펠레트론가속기를 사용하여 10에서 90keV 영역에 대하여 $^{197}Au$의 중성자포획 스펙트럼을 측정하였다. 중성자 펄스빔은 $^7Li(p,n)^7Be$반응을 통하여 발생되었다. 사용되어진 양성자 빔의 폭은 1.5-ns였다. 금 시료에 입사된 중성자의 에너지 스펙트럼은 $^6Li$-glass 섬광검출기의 중성자 비행시간법을 사용하여 측정하였다. 금 시료의 중성자포획에 의해서 발생된 감마선은 anti-Compton NaI(TI) 검출장비를 사용하여 측정되었다. 본 연구에서는 5개의 중성자 에너지 역영을 선택했고, 각각의 에너지영역에서 얻어진 감마선파고스펙트럼을 표시하였다. 본 연구에서 얻어진 스펙트럼은 처음으로 얻어진 결과이며, 중성자 결합에너지부근에 몇 개의 천이 피크가 보인다.
Reduction of mycoplasmal lesions and clinical signs by vaccination against Mycoplasma hyorhinis
Lee, Jung-Ah,Hwang, Min-A,Han, Jang-Hyuck,Cho, Eun-Haeng,Lee, Joong-Bok,Park, Seung-Yong,Song, Chang-Seon,Choi, In-Soo,Lee, Sang-Won Elsevier 2018 Veterinary immunology and immunopathology Vol.196 No.-
<P>Porcine mycoplasmal pneumonia is a significant disease problem in the swine industry. The causative agents include Mycoplasma hyopneumoniae and Mycoplasma hyorhinis. M. hyopneumoniae is the major pathogen contributing to the porcine respiratory disease complex, but is difficult to isolate from the respiratory tract and tonsils, whereas M. hyorhinis is not. Although M. hyorhinis is commonly detected in the lungs, the role of M. hyorhinis as a cause of pneumonia remains unclear. Current vaccines for porcine mycoplasmal pneumonia only include M. hyopneumoniae, not M. hyorhinis. M. hyopneumoniae vaccines are widely used, but disease still occurs because of poor vaccine efficacy and possibly the presence of M. hyorhinis. In this study, an inactivated vaccine containing a mixture of M. hyorhinis and M. hyopneumoniae was generated and evaluated for safety, immunogenicity, and protective efficacy against challenge with M. hyorhinis in pigs. The inactivated vaccine induced an antibody response and reduced pneumonic lesions in the lungs and tracheas compared with the non vaccinated group.</P>
