Contracts of carriage evidenced by bill of lading which are made between carrier and unidentified number of the shipper are to a large extent regulated by statute law such as Hague-Visby Rules and Hamburg Rules. These rules qualifies the contractual liberty of parties and especially restrains the carrier from introducing exemption from his liability beyond those admitted by the Rules. However, these Rules are applied only to goods in respect of which a bill of lading or similar document of title has been issued. In this reason, it is possible that liability of carrier in respect of goods shipped could become an issue where electronic bill of lading is used instead of paper bill of lading because electronic bill of lading is not generally recognised document of title in existing rule. Thus, this article discuss the relation between the carrier who create electronic bill of lading and the Rules regulating liability of carrier. Also, new Rules which has been examining in UNCITRAL will be introduced.

International Trade has led to the increase of the demand of international transport, and also the development of international transport not only incurs claims concerning transportation but also establishes various international rules to settle the claims between the shippers and carriers incurred in the course of transport. With a view to settling the claims successfully, the men who are concerned in the transport have to know the principle and scopes of carrier's liability. In this paper, I would like to find out the scopes of liability of multimodal carriers based on the principles of liability. In order to perform the purpose of this study, I classify the liability principle of the international carrier under the UNs Convention on International Multimodal Transport of Good(1980) and UNCTDAD/ICC Rules(1991) in three system-Network Liability System, Uniform Liability System and Modified Liability System. And that I show the results-the scopes of multimodal carriers' liability based on the UN's Multimodal Convention(1980) and the ICC/UNCTAD Rules(1991), and transport vehicles.

최근 캐리어를 이용한 액체막의 연구가 대단히 활발하다. 항생물질의 모넨신을 사용하여 옥타놀의 유기용매에 용해시켜 양이온교환막을 제조하였다. 이막의 평가를 Nernst-Planck식과 Fick식으로 막전위와 물질의 투과선택도를 분석하였다. 사용한 알카리이온의 농도에 대한 높은 투과선택성을 확인하였고, 시간에 따른 이온농도값은 선형관계를 알았다. 그러나 이온의 높은농도에서 변화량은 선형이 아니였다. 이를 위한 해석은 정지층(Stagnent Layer)을 하나 더 도입하여 업 - 힐 수송에서 직선관계를 얻었다.

This study examined the charge carrier photogeneration and hole transport properties of blends of poly (9-vinylcarbazole) (PVK), $\pi$-conjugated polymer, with different weight proportions (0~29.4 wt%) of (PEA)$VOPO_4{\cdot}H_2O$ (PEA: phenethylammonium cation), a novel organic-inorganic hybrid material, using IR, UV-Vis, and energy dispersive spectroscopy (EDS), thermogravimetric analysis (TGA), steady state photocurrent (SSPC) measurement, and atomic force microscopy (AFM). The SSPC measurements showed that the photocurrent of PVK was reduced by approximately three orders of magnitude by the incorporation of a small amount (~12.5 wt%) of (PEA) $VOPO_4{\cdot}H_2O$, suggesting that hole transport occurred through the PVK carbazole groups, whereas a reverse trend was observed at high proportions (>12.5 wt%) of (PEA)$VOPO_4{\cdot}H_2O$, suggesting that transport occurred via (PEA)$VOPO_4{\cdot}H_2O$ molecules. The transition to a trap-controlled hopping mechanism was explained by the difference in ionization potential and electron affinity of the two compounds as well as the formation of charge percolation threshold pathways.

The transport of Chromium(Vl) ion from waste water throughl the liquid surfactant membrane containing tri-n-octylamine as a carrier, was analyzed by a slab model and was investigated through experiments. For the experiment of membrane stability, concentrations of surfactant and liquid parafnn oil were analyzed. Extraction euperiments were carried out to observe the effect of system variables, such as stirring speed, concentration of carrier, and NaOH in internal aqueous phase, and concentrations of H$_2$SO$_4$and initial chromium(VI) ion in external aqueous phase at $25^{\circ}C$. It is concluded that the most stable formation of liquid membrane emulsion was obtained when surfactant concentration is above 3 wt. ％ and liquid parafnn oil concentration is 50 vol. ％. The transport of chromium(VI) ion in bacth extractor increased with increasing carrier concentration, the volume ratio of emulsion to external aqueous phases, and initial concentration of chromium(VI) ion under the optimum stirring speed of chromium(VI) ion below 2 ppm. The theoretical equation on the transport of chromium(Vl) ion agreed well with the experimental results.

본 논문에서는 다중 양자 우물 레이저 다이오드의 동적 특성을 해석하기 위해 정공에 의해 캐리어 전송이 주관된다는 가정 하에 새로운 형태의 비율방정식을 제시하였다. 제시된 비율방정식을 바탕으로 다중 양자 우물 레이저 다이오드의 직류 과도 응답 및 교류 주파수 응답의 해석을 시도하였다. 이로부터, 정상상태에서 우물간 캐리어 전송 효과의 영향으로 우물마다 캐리어 농도가 불균일함을 확인하였다. 또한 우물의 개수가 많아지면 우물간의 캐리어 전송의 영향으로 변조속도가 제한될 수 있으며, InGaAlAs 전위 장벽이 이러한 점을 개선하는데 유리함을 확인하였다. 고속 직접 변조를 위한 다중 양자 우물 레이저 다이오드의 최적화된 구조 설계시, 본 논문에서 제시된 해석 방법은 유용하게 사용될 것으로 기대된다.

In this paper, the light emitting efficiency, spectrum, and the lifetime of the phosphorescent devices, whose emission characteristics are strongly dominated not only by the energy transfer but also by the charge carrier trapping induced by the emissive dopant, are explained by differences in the energy levels of the host, dopant, and nearby transport layers. On the basis of our finding on device performance and photocurrent measurement data by time-of-flight (TOF), we investigated the effect of the difference of carrier trapping dopant and properties of the host materials on the efficiency roll-off of phosphorescent organic light emitting diode (OLED), along with a physical interpretation and practical design scheme, such as a multiple host system, for improving the efficiency and lifetime of devices.

Government tries to revise the article 25 in Korea Maritime Transport Act which describes subject of coastal carriage for exported-imported container cargoes. The subject of coastal carriage will be replaced coastal carrier by ocean liner carrier according to the revised article 25. By adopting the revised article, coastal shipping industry will be deteriorated in terms of returns on investment, sales and etc. Even though the revision is inevitable to harmonize the flow of exported-imported container cargo movement, coastal shipping industry should be developed and restructured to get competitive power and to set up an efficient international logistics system. To enhance competitive power of coastal shipping companies successfully, government must realize the importance of coastal shipping, and aid the industry through various methods such as arrangement of law and regulation, indirected financial assistance, decrease of tax rate, etc.

A cause and counterplan of the increase in dark decay rate of$\varepsilon$-CuPc/PVCz photoreceptor which is consist of the carrier generation layer (CGL) of$\varepsilon$type copper phthalocyanine ($\varepsilon$-CuPc) thin film by an aqueous coating method and the carrier transport layer (CTL) of polyvinylcarbazol (PVCz) by spin coating, are studied in this paper. Electrochemical deposition of CGL was accompanied by an increase in work function of the aluminium substrate during the processes and the enhanced work function 5.3 eV rose above the ionization potential 5.16 eV of $\varepsilon$-CuPc. This resulted in the increased injection of holes from substrate into CGL and a fast dark decay rate. Improved photoreceptor, an electron-transport $\varepsilon$-CuPc/TNF photoreceptor, led to lowing of dark decay rate and increasing of photosensitivity. The carrier generation efficiency (ηg), carrier injection efficiency (ηi) and xerographic gain (G) of the $\varepsilon$-CuPc/TNF photoreceptor were obtained by XTOF method and PIDC.

The purpose of this paper is to describe the contents and issues of the draft legislation of Part VI the Carriage by Air of Korean Commercial Code in respect of the domestic carriage of cargo by air, comparing to the related provisions of the Montreal Convention of 1999 for the unification of certain rules for international carriage by air and the related provisions of Korean Commercial Code in respect of the carriage by land and sea. The Montreal Convention in respect of the international carriage by air was adopted in 1999, and Korea has ratified the Montreal Convention in 2007. However, there is now no national legislation in respect of the carriage by air in Korea. Thus, the Ministry of Justice has prepared the draft legislation of Part VI the Carriage by Air of the Korean Commercial Code in July 2008, and the draft legislation is now being reviewed by the National Assembly. The draft provisions of Part VI the Carriage by Air are basically adopting most of the related provisions of the Montreal Convention in respect of the carriage of cargo by air and some draft provisions are applying the related provisions of the Korean Commercial Code in respect of the carriage of cargo by land and sea. In respect of the carriage of cargo by air, the contents of the draft legislation of Part VI the Carriage by Air are composed of the provisions in respect of the liability of the carrier, the rights of the consignor and consignee, the transport document and others. In respect of the carriage of cargo by air, the issues on the draft legislation of Part VI the Carriage by Air are the problems with respect to the extinguishment of the liability of the carrier, the application for the non-contractual claim, the liability limit of the servants or agents of the carrier, the right of disposition of cargo, the effect of breach of the provision in respect of the air transport document, the prescription of claim of the carrier, the immunity reasons from liability of the carrier for the loss or damage of the cargo, the making out of the air waybill, and the effect of the statement of the air transport document. In conclusion, the national legislation of Part VI the Carriage by Air of the Korean Commercial Code will protect the right and interest of the consignor and consignee, and clarify the right and duty of the parties to the air transport. Also it will contribute to the development of the air transport industry in Korea.
