  • This paper describes on the consolidation of AIS and ARPA radar positions by comparing the AIS and ARPA radar information for the tracked ship targets using a PC-based ECDIS in Busan harbor, Korea. The information of AIS and ARPA radar target was acquired independently, and the tracking parameters such as ship's position, COG, SOG, gyro heading, rate of turn, CPA, TCPA, ship s name and MMSI etc. were displayed automatically on the chart of a PC-based ECDIS with radar overlay and ARPA tracking. The ARPA tracking information obtained from the observed radar images of the target ship was compared with the AIS information received from the same vessel to investigate the difference in the position and movement behavior between AIS and ARPA tracked target ships. For the ARPA radar and AIS targets to be consolidated, the differences in range, speed, course, bearing and distance between their targets were estimated to obtain a clear standards for the consolidation of ARPA radar and AIS targets. The average differences between their ranges, their speeds and their courses were 2.06% of the average range, -0.11 knots with the averaged SOG of 11.62 knots, and $0.02^{\circ}$ with the averaged COG of $37.2^{\circ}$, respectively. The average differences between their bearings and between their positions were $-1.29^{\circ}$ and 68.8m, respectively. From these results, we concluded that if the ROT, COG, SOG, and HDG informations are correct, the AIS system can be improved the prediction of a target ship's path and the OOW(Officer of Watch) s ability to anticipate a traffic situation more accurately.

  • Im sog. Kemptener-Fall aus dem Jahre 1994 in Deutschland hat der 1. Strafsenat des BGH die Bedeutung des Patientenwillens erstmals $f{\ddot{u}}r$ einen solchen Fall hervorgehoben, in dem die Krankheit noch keinen irreversibel $t{\ddot{o}}dlichen$ Verlauf genommen hat. Der 1. Senat des BGH entwickelt aus den $Pr{\ddot{a}}missen$, die er in drei $Leits{\ddot{a}}tzen$ $festh{\ddot{a}}lt$, $schl{\ddot{u}}ssig$ und im $gel{\ddot{a}}ufigen$ Modus der Dogmatik eine $Begr{\ddot{u}}ndung$, die gleichwohl den weitaus ${\ddot{u}}berwiegenden$ Teil der eigentlichen Probleme des Falles nicht einmal sichtbar genacht, geschweige denn einer $L{\ddot{o}}sung$ $n{\ddot{a}}hbar$ $br{\ddot{a}}chte$. Die $Leits{\ddot{a}}tze$ formulieren rechtliche Prinzipien, beziehen aber unvermeidlich zugleich und $selbstverst{\ddot{a}}ndlich$ Stellung zu einigen der schwierrigsten und $ungel{\ddot{o}}sten$ ethischen Fragen der modernen Medizin. Im sog. Kemptener-Fall brachte die $L{\ddot{o}}sung$ des Senat $f{\ddot{u}}r$ Mediziner, Ethiker und Juristen keine befriegende $L{\ddot{o}}sun$, sondern allein zahlose Zweifel und Unklarheiten. Denn dabei geht es nicht um moralisch $unerw{\ddot{u}}nschten$ Ergebnis der Rechtsanwendung im Einzelfall. Vielmehr hat die moderne Medizin $f{\ddot{u}}r$ den ${\ddot{a}}rztlichen$ Eintscheidungsbereich zwischen Leben und Tod einen Typus professionellen Alltagshandelns gebracht. Deshalb ist es eine Illusion, wollte man von der strafrechtlichen Dogmatik befriegende Resoltate erwarten. Trotzdem kann man nicht die dogmatische Untersuchung $aufh{\ddot{o}}ren$, weil eine Gesetzgebungslehre oder eine Strafrechtspolitik von den dogmatischen Probleme ausgehen muss. In diesem Hintegrund im Beitrag wurde dieser Fall durch kriti sche Auseinandersetzung strafrechtsdogmatisch zu begrunden versucht, Dabei wird die $Interessenabw{\ddot{a}}gung$ zwischen Lebens- und Sterbensinteressen als der $Rechtfertigungsbegr{\ddot{u}}ndung$ beim $t{\ddot{o}}dlichen$ Behandlungsabbruch vertreten.

  • Etoricoxib features antioxidant and anti-inflammatory properties concomitantly, suggesting that it may be beneficial in testicular ischemia reperfusion (I/R) damage. Our aim is to investigate the effects of etoricoxib on testicular I/R damage induced with torsion-detorsion (TD). The etoricoxib + torsion-detorsion (ETD) groups of animals were given etoricoxib in 50 and 100 mg/kg of body weight (ETD-50 and ETD-100), while the testes torsion-detorsion (TTD) and sham operation rat group (SOG) animals were given single oral doses of distilled water as a solvent. TTD, ETD-50 and ETD-100 groups were subjected to $720^{\circ}$ degrees torsion for four hours, and detorsion for four hours. The SOG group was not subjected to this procedure. Biochemical, gene expression and histopathological analyses were carried out on the testicular tissues. The levels of malondialdehyde (MDA), myeloperoxidase (MPO), interleukin-1 beta ($IL-1{\beta}$) and tumor necrosis factor alpha ($TNF-{\alpha}$) were significantly higher, and the levels of total glutathione (tGSH) and glutathione reductase (GSHRd) were significantly lower in the TTD group, compared to the ETD-50, ETD-100 and SOG groups. Etoricoxib at a dose of 100 mg/kg better prevented I/R damage than the 50 mg/kg dose. Etoricoxib may be useful in clinical practice in the reduction of I/R damage on testes caused by torsion-detorsion.

  • 태양전지의 공정중 고온공정을 줄여줌으로서 최종 태양전지의 가격을 저가화할 수가 있다. 이 논문은 점액 상태의 인을 희석시켜서 접촉 홈에 확산공정을 마친 후, 그 기본 특성을 조사하였다. 점액상태점의 희석도와 스핀속도가 산화막의 두께에 영향을 미치는 것이 확인되었다. 희석도가 높을수록 산화막은 두꺼워지고 균일도는 낮아졌다. 희석도 60%의 인이 홈에서의 균일도와 깊이를 고려할 때 가장 적당한 것으로 사료된다.

  • In this report, the FE characteristics of carbon nanotubes (CNTs) treated using both thermal annealing and mechanical coatings on the as-grown CNTs system atically studied. It was found that in the high temperature annealed samples, CNTs were attacked at its root during annealing due to a small amount of oxygen, and were pulled out of the substrate in places after FE measurements because of the contact resistance. However, for the mechanically coated samples both with spin on glass (SOG) and polymethyl methacrylate (PMMA), CNTs were found to be nearly intact after FE measurements and showed reliable FE characteristics over repeatable voltage scan. The reliability of CNTs during FE could be owing to the strong adhesion of CNTs to the substrate both by SOG and PMMA coatings.

  • The application of advanced oxidation for the treatment of oil refinery wastewater under UV radiation by using nanoparticles of titanium dioxide was investigated. Synthetic wastewater prepared from phenol crystals; Power Glide SAE40 motor vehicle oil and water was used. Response surface methodology (RSM) based on the Box-Behnken design was employed to design the experimental runs, optimize and study the interaction effects of the operating parameters including catalyst concentration, run time and airflow rate to maximize the degradation of oil (SOG) and phenol. The analysis of variance and the response models developed were used to evaluate the data obtained at a 95% confidence level. The use of the RSM demonstrated the graphical relationship that exists between individual factors and their interactive effects on the response, as compared to the one factor at time approach. The obtained optimum conditions of photocatalytic degradation are the catalyst concentration of 2 g/L, the run time of 30 min and the airflow rate of 1.04 L/min. Under the optimum conditions, a 68% desirability performance was obtained, representing 81% and 66% of SOG and phenol degradability, respectively. Thus, the hydrocarbon oils were readily degradable, while the phenols were more resistant to photocatalytic degradation.

  • SOG박막 밑에 층간 절연박으로 사용하는 PECVD산화막을 Si rich산화막으로 만들어 줌으로써 실리콘 dangling bond가 수소원자나 수분과 결합하여 SOG박막으로 부터 침투되는 수소원자나 수분의 확산을 억제하므로서 소작 열화되는 것을 방지한다. 이러한 Si rich산화막의 기본 특성을 알아보기 위하여 LF/HF power비와 $SiH_4/N_2O$ gas유량비를 변화시켜서 박막 특성을 조사하였다. 저주파 power만 변화시킨 경우, 증착속도가 감소하고 굴절율과 압축응력에 증가하며 FTIR에서 3300$\textrm{cm}^{-1}$~3800$\textrm{cm}^{-1}$영역의 수분에 의한 peak이 감소하는 것으로 보아 박막이 치밀해짐을 알 수 있고, $SiH_{4}$기체유량을 증가시킨 경우엔 증착속도, 굴절율, 식각속도는 증가하나 압축응력은 감소한다. FTIR에서 Si-O-Si peak의 세기가 감소하고 낮은 파수영역으로 이동하며, AES분석 결과에서 일반적인 oxide(Si:0=1:1.98)에서 보다 Si:O비가 1:1.23으로 낮아 PECVD산화 막내의 Si danling bond가 증가했음을 알 수 있었다.
