Researches on military weapons are actively studied to improve national defense power of each country. The military weapon system is being used not only as a weapon but also as a reconnaissance and surveillance device for places where it is difficult for people to access. If such a weapon system becomes an object of attack, military data that is important to national security can be leaked. Furthermore, if a device is taken, it can be used as a terrorist tool to threaten its own country. So, security of military devices is necessarily required. In order to enhance the security of a weapon system such as drone, it is necessary to form a chain of trust(CoT) that gives trustworthiness to the overall process of the system from the power on until application is executed. In this paper, by analyzing the trusted computing-based boot technology, we derive trusted boot technology components and classify them based on hardware dependence/independence. We expect our classification of hardware dependence/independence to be applied to the trusted boot technology of our self-development ultra- precision weapon system to improve the defense capability in our military. 세계으로 국방력 향상을 해 정무기체계에 한 연구가 활발히 진행되고 있다. 정무기체계는 무기로 사용될 뿐만 아니라 사람이 근하기 힘든 장소의 정찰 감시 역할도 수행하기 때문에 그 활용성이 차 확장되고 있다. 이러한 무기체계가 공격의 상이 될 경우, 국가 안보에 요한 군사 데이터가 유출될 수 있고, 더 나아가 기 기가 탈취될 경우 오히려 자국을 하는 테러 도구로 사용될 수 있기 때문에 이와 같은 을 방지하기 해서는 무기 체계에 한 보안이 매우 요하다. 이러한 무기체계의 보안을 유지하기 해서는 원이 인가된 시부터 응 용로그램이 실행되기까지 시스템 운용의 반인 모든 과정에 신뢰성을 부여하는 신뢰체인을 형성하는 것이 필 요하다. 따라서 본 논문에서는 신뢰성 부 기술 분석을 바탕으로 신뢰성 부 기술을 구성하는 요소 기술들을 도출 하고 하드웨어 종속/독립성을 기으로 분류한다. 본 논문에서 분류한 하드웨어 종속/독립성에 따라 분류한 신뢰성 부 구성 요소를 바탕으로 신뢰성 부 기술을 용하기 해 필요한 최소한의 하드웨어 종속인 구성 요소를 제 시하여 우리 군에서 국방력 향상을 해 자체개발하는 정무기체계 설계에 용될 수 있을 것으로 기된다.

朴建鎬 圓光大學校大學院 1984 學位論叢 Vol.13 No.-

For the increase of soybean yield in newly reclaimed area, this experiment was carried out in Kimje (plain area) and Jinan (hilly area) to determine the effect of nitrogen topdressing on agronomic characters. grain yields, protein and oil contents of soybean in 1982~1983. The results obtained were summarized as follows; 1. During growing period, average mean temperatures were similar, but amounts of rainfall and sunshine hours were smaller in Jinan than in Kirn je. 2. Applications of sufficient amounts of phosphates and lime increased available P20S and exchangeable Ca contents on both soils to optimum levels within one year after reclamation. 3. Days required for flowering (days from sowing to flowering) were shortened as sowing dates were later. 4. Nitrogen topdressing at flowering shortened the length of branches, but increased number of branches per plant, thus preventing over-thriving and lodging as compared with basal fertilization. 5. Nitrogen topdressing at flowering increased number of pods per plant and weight of 100 seeds. 6. Significant positive correlation were observed between grain yield and stem length, number of branches per plant, number of pods per plant, and weight of dry matter. 7. A significant negative correlation was obtained between grain yield without topdressing and yield increasing index by topdressing. The result indicates that nitrigen topdressing may be very effective practice III newly reclaimed area. 8. Soybean seeds produed in Jinan had higher protein contents than there of in Kimje. Higher protein contents in grains were noted with nitr ogen topdressing than without topdressing (only basal fertilization). Tendency of oil content was just opposite to above results of protein content. The protein content was significantly negative correlates with oil contents, regardless of area and varieties. 9. Total nitrogen content by Danyeobkong(medium type) plants was increased continuously until maturing stage, but that by Kwangkyo (limited type) plants showed the peak at 30 days after flowering. Total nitrogen content by plants at 30 days after flowering was significantly correlated with grain yield of soybeans. 10. The order of distribution ratio among plant parts in nitrogen content at maturing stage was mainstem < branch < pod < seed. The distribution ratio in seed was highest in the plants that receiving nitrogen topdressed at flowering. 11. Application of 8kg/l0a nitrogen as only basal fertilization inhibited formation of nodules in soybean roots, and nitrogen topdressing tended to decrease their sizes. 12. Topdressing of 4kg/10a nitrogen at flowering stage increased grain yields by 23-36% and 18-27% in Danyeobkong, and by 15-56% and 20-28% in Kwangkyo , III Kimje and Jinan respectively.

박건호,이준웅 광운대학교 신기술연구소 1996 신기술연구소논문집 Vol.25 No.-

본 연구에서는 송배전 계통에서 변성기의 몰드 재료로서 널리 사용되고 있는 에폭시 수지를 시료로 하여 설정해 높은 배합비에 따라 5종으로 제작한 각 시편에 대해 절연 파괴 실험을 하였다. 절연파괴 데이터를 가지고 와이블 분포식을 이용하여 임의의 허용 파괴 확률에서의 허용인가 전계의 값을 추정하였으며 절연 안전성을 판단하기 위하여 경년 열화(經年劣化) 데이터의 통계 처리를 행한 결과 허용 파괴 확률을 0.1[%]로 하였을 때, 허용 인가 전계는 21.5[kV/mm] 이하가 되어야 함을 확인할 수 있었다. In this study, the dielectric breakdown of epoxy composites used for transformers was experimented and then its data were simulated by Weibull distribution probability. The more hardener increased the stronger breakdown strength at low temperature because of cross-linked density by the virtue of ester radical, and the breakdown strength of specimens with filler was lower than it of non-filler specimens because it is believed that the adding filler forms interface and charge is accumulated in it, therefore the molecular motility is raised, the electric field is concentrated, and the acceleration of electron and the growth of electron avalanche are early accomplished. From the analysis of Weibull distribution, it was confirmed that as the allowed breakdown probability was given by 0.1[%], the applied field value needed to be under 21.5[kV/mm].

Comparative Evaluation of Mn(II) Framework Substitution in MnAPSO-34 and Mn-impregnated SAPO-34 Molecular Sieves Studied by Electron Spin Resonance and Electron Spin Echo Modulation Spectroscopy

박건호,김양희,조영수,이용일,이철위 한국자기공명학회 2002 Journal of the Korean Magnetic Resonance Society Vol.6 No.1

영어논문 MnAPSO-34 and Mn-impregnated SAPO-34(Mn-SAPO-34) sample were prepared with various manganese contents and studied by electron spin resonance(ESR) and electron spin echo modulation(ESEM). Electron spin echo modulation analysis of 0.07mol % Mn(relative to p) in MnAPSO-34 with adsorbed D2O shows two deuteriums at 0.26 nm and two at 0.36 nm from Mn. This suggests that two waters hydrate an MnO4 configuration with a D-O bond orientation for the waters as expect for a negatively charged site at low manganese content (0.1 mol%), the ESR spectra of MnAPSO-34 and MnH-SAPO-34 exhibit the same parameters(g  2.01 and A  89 G), but the spectra obtained from MnAPSO-34 samples are better resolved. The decomposition temperature of as-synthesized MnAPSO-34 were in the range of 200 – 600 oC of the morpholine which is 12 oC higher than that in as-synthesized MnH-SAPO-34. Infrared spectra showed that the position of a band at 3450 cm-1 shifted about 15 cm-1 toward higher energy in MnAPSO-34 versus MnH-SAPO-34. The modulation depth of the two-pulse ESE of MnAPSO-34 with adsorbed D2O is deeper than that of MnH-SAPO-34 with adsorbed D2O. Three-pulse ESEM of MnAPSO-34 and MnH-SAPO-34 with adsorbed deuterium oxide shows that the local environments of manganese in the hydrated samples are different, suggesting that Mn(II) is framework substituted in MnAPSO-34 since it obviously occupies an extraframework position in MnH-SAPO-34.

Manganese-doped H-SAPO-34 samples were prepared by an ion-exchanged reaction between H-SAPO-34 and paramagnetic Mn(II) species in methanol media and characterized by ESR and Electron Spin-Echo Modulation(ESEM) studies. In the hydrated (W)MnH-SAPO-34 measured in water, the Mn(II) ion was octahedrally coordinated with four framework oxygens and two water molecules at a displaced site IV of the eight membered ring window in the ellipsoidal cavity, while the Mn(II) ion was octahedrally coordinated to three framework oxygens and three water molecules at a displaced site I’ of the six membered ring window in the ellipsoidal cavity in hydrated(M)MnH-SAPO-34 measured in methanol. The similar result was found in the experiments with methanol adsorbents except ethanol. 영어논문

박건호,이성복,백진,최대균,Park, Geon-Ho,Lee, Sung-Bok,Bak, Jin,Choi, Dae-Gyun 대한치과보철학회 2007 대한치과보철학회지 Vol.45 No.5

Statement of problem: In the Protar articulator, the models are almost parallel with the Camper's plane. The ultrasonic-based ARCUSdigma system is basis for the determination of dynamic function parameters with so-called "articulator related registration". Purpose: The purpose of this study was to compare the sagittal condylar guidance angles found by use of the wax protrusive records in a semi-adjustable articulator(KaVo Protar 7) with those found by use of the Axiograph (ARCUSdigma). 83 volunteers with intact dentition participated in this study after obtainment of informed consent. Material and method: The sagittal condylar guidance angles were measured and estimated statistically by semi-articulator and Axiograph. All the readings were in degrees. No control was used in this project. To test whether there was a significant difference between the 2 independent samples, paired t-test and Kruskal-Wallis test were carried out(p=.05). Results: 1. The mean results for the wax protrusive records were as follow: right side (32.65 degrees, SD 16.48); left side (33.27 degrees, SD 17.49). 2. The mean results for the Axiograph were as follow: right side (32.26 degrees, SD 7.00); left side (33.07 degrees, SD 7.58). 3. There was no statistical difference on the wax protrusive records and Axiograph(p>0.05). Conclusion: Both methods of wax protrusive records and Axiograph are clinically acceptable for measuring the sagittal condylar guidance angles in semi-adjustable articulators.
