An ocean buoy was deployed 10 km off Donghae city, Korea at a depth of 130 m to measure meteorological (air pressure, air temperature, wind speed, wind gust, wind direction, relative humidity) and oceanographic data (water properties and currents in the whole column) in real-time. The buoy recorded a maximum wind gust of 25 m/s (10 minutes' average speed of 20 m/s) and a minimum air pressure of 980 hPa when the eye of typhoon Maemi passed by near the Uljin city, Korea at 03:00 on 13 September 2003. The wave height reached maximum of 9 m with the significant wave height of 4 m at 04:00 (1 hour after the passage of Maemi). The currents measured near the surface reached up to about 100 cm/s at 13:00 (10 hours after the passage of Maemi). The mixed layer (high temperature and low salinity) thickness, which was accompanied by strong southward current, gradually increased from 20 m to 40 m during the 10 hours. A simple two layer model for the response to an impulsive alongshore wind over an uniformly sloping bottom developed by Csanady (1984) showed reasonable estimates of alongshore and offshore currents and interface displacement for the condition of typhoon Maemi at the buoy position (x=8.15 km) during the 10 hours.

In this study I tried to examine the origin of the Codex Theodosianus, first official code of the Roman Empire. Theodosius II summoned in 429 the first committee for the compilation of this code and it was finally published in 438. Three constitutions, C. Th., I 1,5-6 and Novellae Theodosii 1, contain the historical process of compilation of the code and I presented my interpretation with their latin texts. Originally the first committee had a plan to publish two different Codices: one was destined to an intermediary code, while the other would have to be the perfect Codex without any errors, including legal theories of several jurisprudents. Nevertheless, it was principally because of the so-called the christological controversy of Epesus in 431 that the committee failed to accomplish its mission. Only in winter 435 after the exile of Nestorius, bishop of the capital of the Eastern Empire, Theodosius II ordered to organize his second committee, but only to aim at the intermediary Codex of which the title was named after himself. Finally the second committee accomplished its own task, publicizing the Codex Theodosianus in 15 february 438.

In this study I tried to compare the film Agora(2009) with its historical sources from the 4th-5th centuries. The film used the Christian Roman Empire of the period as its background. Its plot was formulated so that the destruction of the Alexandrian Serapeum at the end of the 4th century was connected to the Jewish persecution and Hypatia's death in the early 5th century. The drama of Agora differs, in many aspects, from the history preserved in the texts. According to the Ecclesiastical History of Rufinus, it was Theophilus of Alexandria to whom was attributed the cause of the pagan riot of 391-392. It is accepted that Synesios studied under Hypatia in the 390's, but at that time he was not Christian but pagan. Orestes, Praefectus Augustalis of Egypt in 414-415, was not a disciple of Hypatia. Furthermore I tried to prove the fact that the Rescriptum of Theodosius did not state verbatim that both the demolition of the temple of Serapis and the destruction of the Library occurred. Nevertheless the temple was levelled to the ground, while it is more probable that the Library was saved even inspite of the fanatic religious violence. In the Jewish persecution and the death of Hypatia, fiction plays an important role. Agora described the instigating cause of the Jewish persecution as the stone throwing of the Parabalani, nurse-monks who cared for the sick in the hospital organized by the Alexandrian Church. This sort of intrigue is not what the church historian Socrates describes. It is also fictive rather than historic that Synesios mediates between Cyril and Orestes, and persuades Hypatia to receive baptism. The emotion of love that both the slave Davos and Orestes feel toward Hypatia is totally imaginary even though it has crucial importance in the plot of Agora. Nevertheless the film Agora succeeds in expressing superbly and beautifully all opposing notions such as religion and power, violence and sacredness, love and truth.

Sagnac 간섭계를 이용한 광섬유 음향 센서의 동적 범위 향상 기법

남성현(Sung Hyun Nam) 한국센서학회 2000 센서학회지 Vol.9 No.6

A new demodulation technique which can be used for the fiber optic acoustic sensor system using Sagnac interferometer is described. The theoretical limitation in dynamic range of the quadrature demodulation technique can be removed by the proposed BPSK(Binary Phase Shift Keying) demodulation technique. Full demodulation of input acoustic signal is possible with just simple electronics by eliminating the necessity of the high frequency phase modulation. This technique is suitable for digital signal processing of fiber optic sensor systems and can be applicable for other interferometers.

HMIPv6에서의 MAP의 부하 제어 및 경로 최적화

남성현(Sung-Hyun Nam),이경근(Kyung-Geun Lee) 대한전자공학회 2008 전자공학회논문지TC (Telecommunications) Vol.45 No.12

HMIPv6는 효율적인 핸드오버를 제공하고 시그널링 오버헤드를 줄이기 위한 기술로 주목받고 있다. HMIPv6는 이러한 시그널링 오버헤드와 지역적 이동성 관리를 위해 MAP(Mobility Anchor Point)를 도입한다. MAP는 빈번한 핸드오버가 발생하는 HMIPv6 네트워크 환경에서 효율적인 이동성 관리를 이룬다. 그러나 HMIPv6는 특정한 MAP로의 부하집중과 같은 네트워크 안에 존재하는 MN(Mobile Node)와 CN(Correspondent Node)사이의 불필요한 지연을 발생시킨다. 또한 모든 패킷은 MAP를 경유하여 전송되기 때문에 MAP는 HMIPv6 네트워크에서의 경로 최적화를 방해한다. 본 논문은 HMIPv6 네트워크에서 MAP의 부하에 따라 경로를 최적화하는 방법을 제안한다. 제안하는 방법은 MAP도메인 안에서 최적의 서비스를 제공하기 위한 임계값을 설정하고 MAP에 연결된 이동노드의 수가 임계값을 넘어서는 경우에 MAP를 거치지 않고 AR(Access Router)로 직접 전송하도록 한다. 이에 따라 제안하는 방법은 시그널링 비용을 줄일 뿐만 아니라 특정한 MAP의 부하집중을 완화시킨다. HMIPv6 draws lots of attentions in recent years for providing an efficient handover and reducing the signaling overhead. HMIPv6 employs MAP(Mobility Anchor Point) in order to minimize a signaling overhead and a local mobility management. MAP completes an efficient mobility management in HMIPv6 network environment with frequent handover. However, HMIPv6 causes load concentration at a paricular MAP and may have unnecessary latency between MN(Mobile Node) and CN(Correspondent Node) within the same network. A MAP may also disturb the route optimization in HMIPv6 network because all packets must be transmitted through a MAP. In this paper, we propose a scheme to optimize the route in HMIPv6 networks according to MAP load. We configure a threshold in order to support the better service into MAP domain. The packets do not pass through MAP and are directly transmitted to AR(Access Router) if the number of current MNs attached to the MAP exceed the desired threshold. We simulate the performance of the proposed scheme and compare with HMIPv6. Resultly, the proposed scheme reduces signaling costs and mitigates concentration of a paticular MAP as well.

로마법과 기독교: 간통 및 이혼에 관한 로마법 전통과 4-6세기 기독교 시대의 칙법 전통

In this study, I focused my arguments on what aspects the laws about the adultery and the divorce have been changed from the classical Roman law to the Christian period of the 4th-6th. First, I examined the Augustan law about the adultery, enacted about B. C. 18 and called often “Julian law for adultery repression.” The Julian law for adultery repression considered that the adultery was woman's sin. It offered to the husband and the married woman's father a right killing (ius occidendi) the adulterer without penalty. According to the Julian law, the husband had to divorce his wife before he accused her of adultery. If the adultery is proven, the adulterer and the adulteress were sentenced to a economic loss. In the period of Constantine, the fundamental notion of the Julian law and the Ius Occidendi were still unchanged. But the woman had to be divorced by his husband only after she was accused and proved guilty. And Constantine sentenced the death penalty to the adulterer and the adulteress, while Justinianus confined the latter in the monastery. As to the divorce, the Roman legal tradition sustained the marriage by marital affection (maritalis affectio) and the divorce by consent of two parties. But Constantine and Justinianus attempted to intervene a Roman custom of free divorce. Constantine promulgated a constitution limiting the unilateral divorce (repudium), but his law was made void twice and was vivified by Theodosius who lightened the conditions of the divorce and the penalty. On the other hand, Justinianus interdicted the bilateral divorce (divortium) but his law had to be recalled soon by Justine II, because it was contrary to the spirit of the Roman law about the marriage and the divorce by free consent.
