The purpose of this paper is to shed the light on one of the most important influential factors for the development the Palestinian economy, which is logistics system. The discussion about the Palestinian state and its economy arise after the UN General Assembly voted to grant Palestine a nonmember state. Palestine is considered land-locked country, although it has seashore. Although Palestine has seashore, it is considered land-locked country due to the lack of sovereign logistics infrastructure. International Trade with Israel, Jordan, and Egypt is done through land border crossings. Palestinian international trade to European, Asian, and American countries is currently done through Israeli airports and seaports. Almost 99% of the Palestinian imports are through land. Israeli policies and procedures incur Palestinian exports additional transportation costs when delivering their products to Israeli ports and Airport and even when transit these cargos to neighboring countries through Israeli controlled areas. Therefore, without direct access to international markets, the Palestinian economy will not be able to compete in international markets, and will continue its dependence on the Israeli economy. Considering that the current situation will continue, alternative routes for international trade to avoid using the Israeli ports are Aqaba Port in Jordan and Port Said in Egypt. In the long term, having a seaport and Airport in Gaza, Airport in the West Bank, and constructing the Corridor connecting Gaza and the West Bank, is the only solution capable for independently integrating the Palestinian economy with the region and other countries in the world, and therefore creating competitive advantage for the Palestinian exports.

For the Palestinians, what is the impact of the Arab Spring? The revolution not only dislodged Mubarak from the presidency, but also changed Egyptian policy regarding Palestinians in Gaza. New Egyptian diplomacy has encouraged Hamas and Fatah, which had been in dispute, to seek reconciliation and has loosened the border control on humanitarian grounds. We focus on Palestinian voting attitudes in the wake of the Arab Spring. Despite the vast quantity of literature written about Palestinian politics since the first decade of the millennium, we know little about the determinants of Palestinian attitudes toward the divided governments in the West Bank and the Gaza Strip. The Fatah government, in the West Bank, increased in popularity after submitting a request for UN recognition of Palestinian statehood. In Gaza, the Hamas government lost popularity because of mismanagement but won support through the success of its prisoner swap deal with Israel. However, evaluation of the ruling party does not depend only on one-time events. This research attempts to measure the impact of policy change in Gaza after the Arab Spring. We provide an account of our research on Palestinian attitudes toward the divided governments based on two sets of the original survey data conducted in May 2009 and June 2012. The paper sheds light on Palestinian attitudes and makes clear the effects of "democratization" in the Middle East and the effects of regional context factors on the occupied Palestinians.

Morphogenesis of rat retina was studied by light and electron microscope from day 14 of gestation to 55 days after birth. The results indicate as follows: 1. At the outer border of the neuroblastic layer at the 14th day of gestation, cells she wed active mitotic figures which result in the increases of thickness and differentiations of this layer. 2. At birth, rat retina is still in a premature state. But, it is begining to approach its adult condition in appearance till the 9th postnatal day. Particulary photosensitive cells are fully developed by the 14th postnatal day, so they are functional from now on. 3. It is observed that the pigment epithelium begins differentiation at the fetal period, but is not functional urtil birth 4. The pigment epithelium differentiates earlier than the neuroblastic layer. It is suggested that these two layers are so closely associated that the pigment epithelium takes part in the differentiations of the neuroblastic layer. In conclusion, rat retina is differentiated soon after the optic cup formation before the 14th day of gestation, but even new born rat retina is not functional, and then it has function as photoreceptors coincided with the eye opening.

The diagnosis and treatment of early gastrointestinal cancers is the gastroenterologists' mission because of national cancer screening program in South Korea. The detection of early cancers is emphasized, because these were previously treated with surgical treatment can be currently cured with endoscopic treatment. Gastroenterologists who achieved at least on some level can make an exact diagnosis regardless of what type of endoscopy, but generally, there are some required conditions for an optimal diagnosis. First, clinically important lesions have to be detected easily. Second, the border and morphology of lesions have to be characterized easily. Third, lesions have to be diagnosed exactly. Precancers and early cancers are often subtle and can pose a challenge to gastroenterologists to visualize using standard white light endoscopy. The use of dye solutions aids the diagnosis of early gastrointestinal cancers, however, it is a quite cumbersome to use dye solutions all the time and the solution often bothers the exact observation by pooling into the depression or ulceration of the lesion. To overcome this weakness, newer endoscopes are now developed so called "image enhanced endoscopy" using optical and/or electronic methods such as narrow band imaging (NBI), autofluorescence imaging (AFI), i-scan, flexible spectral imaging color enhancement (FICE) and confocal endomicroscopy (CLE).

The surge of cross border trade and transactions has seen international arbitration fast emerging as the preferred mode of dispute resolution. This phenomenon is especially remarkable in the Asian region. The Singapore International Arbitration Centre ("SIAC") aspires to contribute to this growth as one of the leading arbitral institutions. The objective of this article is to provide an insight into the key features of SIAC Rules. This article has been divided into two parts; the first part discusses how the SIAC Rules are helpful in building bridges in international arbitration between the common law and civil law systems. We have attempted to throw light on how the SIAC Rules may be tailored by the parties to bring about a harmonization in the common law and civil law practices in the conduct of the arbitration proceedings. In the second part of the article, we discuss the two most popular procedures introduced in the SIAC Rules in 2010 i.e. 'Emergency Arbitration' and 'Expedited procedures'. The emergency arbitration provisions enable a party to obtain order(s)/award for urgent interim relief(s) upon commencement of arbitral proceedings but pending the constitution of the main Tribunal. The expedited Procedure provisions give parties the option of having their disputes determined in six (6) months from the date of the constitution of the tribunal.

The China entered World Trade Oganization(WTO) last year, thus opening its border to more - and freer - trade. With its foreign trade rapidly expanding and with economic growth continuing at a substantial -rate, China will be the largest container traffic generating country in the world. In the light of this potential trade bonanza, regional ports in North-East Asia strive to gain a competitive-edge. The Port of Busan, the world's third largest container port, wants to capture a significant share of the china's container cargoes. In this circumstance, development strategies of the Port of Busan are suggested as follows. First, to cope with increasing volumes, the New Busan Port on Gaduk island should be constructed without failure. Second, it is necessary to add modernized high-performance gantry cranes and to train crane operators' skill. Third, it needs to apply Dwell Time- Sliding Scale System for transshipment cargoes. Fourth, it needs to develop the EDI network in terminal areas or adjacent hub ports to exchange trustworthy and satisfactory informations Fifth, port authority -needs to enlarge designated Free Trade Zone to facilitate the free flow of cargoes. Sixth, the restoration of rail links between North and South Korea is abundantly clear. Thus it needs to enlarge railroad facilities in advance. Seventh, it needs to establish the Port Authority of Busan immediately. Finally, it needs to strengthen port sales and to open events like 'Marine Week 2001' regularly to attract potential canters or big shippers.

도시기반시설에 첨단 정보통신기술을 융합하여 언제 어디서나 자유롭게 서비스를 제공하고자 하는 U-City(Ubiquitous City)의 공간정보기술은 다양한 형태로 서비스 되고 있다. 그 중에서도 U-City에서 가장 많이 설치되어 있는 CCTV(Closed Circuit TV)의 스테레오 영상을 가지고 특징점(Key Point)을 선정하여 정합(Matching)하고 3차원 공간정보를 구축하는 연구가 진행되고 있다. 하지만 대부분 정합점을 추출하는데 사용된 데이터는 조도와 같은 외부 환경영향을 고려하지 않고 있다. 본 논문은 동일한 하드웨어에서 조도의 변화에 의해 영상의 질이 좌우되는 CCTV를 가지고 3차원 공간정보를 구축하는데 필요한 정합점이 조도에 따라 얼마나 변화 하는지 실험을 하였다. 조도에 따른 정합점 수의 분석 결과, 카메라의 조리개, 셔터속도, 감도를 고정하였을 때 3,000Lux까지 정합점 수가 조도에 비례하여 높아 졌으며, 물체와 배경의 경계가 뚜렷해졌다. 반대로 빛이 과도하게 들어 왔을 경우 화면이 밝이지며, 노이즈가 발생하고 사물과 사물의 경계가 없어져 특징점을 선정하기가 힘들었다. 본 논문에서 얻어진 결과를 이용하여 촬영할 경우 향상된 정합점을 가질 수 있을 것으로 기대된다.

본 연구는 DMSP 위성의 OLS 센서에서 촬영된 Stable Lights 영상자료로부터 랴오닝성과 단둥시의 빛합계 지수를 도출한 후 이 지표와 경제 수준 간 관계를 분석하였다. 랴오닝성의 빛합계 지수는 다른 성급 지역의 평균보다 높은 수준이었고, 지난 20여 년 동안 지속적인 증가 추세를 보였다. 실질 성장률과 1인당 평균 임금 등 이 지역의 경제 수준 향상을 지시하는 경제 지표 변화를 잘 반영한다고 볼 수 있다. 그러나 단둥시의 빛합계 지수는 다른 지급시 평균보다 낮은 수준이었는데, 이는 주요 경제 지표에 기초한 이 도시의 경제적 지위와 맥을 같이하는 것으로 보인다. 이전 시기에 비해 1998~2007년 사이 대북무역이 활성화된 단둥시 시할구의 빛합계 지수의 연간 증가율이 높아졌고, 비슷한 기간 동안 북중 교역액과 북한의 대중 수출액도 증가하는 패턴을 보였다. 이 기간 동안 햇볕정책의 영향으로 남 북한 간 긴장 관계가 완화되었던 것을 비추어볼 때, 빛합계 지수는 단둥시의 지정학 및 지경학의 특성을 설명할 수 있는 공간 대안 지표로 활용될 수 있을 것으로 기대된다.

Xerostomia and xerophthalmia are delicate or serous side effects, occuring when the radiotherapy is administered to the head and neck cancer patient. It is known that the cause of the above side effect is radiosensitivity of serous cells. In this study, the ultrastructural features of the parotid glands of the X-irradiated rats were observed. Sprague-Dawley rats weighing 200-250g each were anesthetized with sodium thiopental, and placed on the Mitsubishi linear accelerator. Only the head and neck areas of animals were exposured at the distance of 80cm, within the area of $30X30cm$, in the depth of 1cm, with the speed of 200R/min. Total doses applied were 3,000R or 6,000R depending on the experimental groups. Animals were sacrificed on the 6th hour, 2nd day and 6th day after the irradiation. Parotid glands were fixed in the 2.5% glutaraldehyde-1.5% paraformaldehyde solution, and followed by refixation in the 1% osmium tetroxide solution. Dehydrated blocks were embedded in araldite mixture, and ultrathin sections were cut. Sections were contrasted with the solution of uranyl acetate and lead citrate, and observed with JEM 100 CX-II electron microscope. The results were as follows: 1. Normal parotid acinar cells are two types; the light and the dark acinar cells. The light acinar cell contains dense secretory granules, whereas dark acinar cells contains granules of medium density with some darker spots within them, or other cells contain granules of medium density with darker rims. 2. Six hours after the irradiation, many acinar cells were degenerated showing variable stages of cytolytic bodies, light bodies, or dense degenerations. Within the acinar cell, Golgi apparatus and granular endoplasmic reticula were most severely altered elements. Granules showed more contrasting densities and irregularities. 3. Two days after the irradiation, some cytolytic bodies, and focal lucent degeneration of cytoplasm, and fine granular alteration of cytoplasmic matrix were pronounced. But other elements including secretory granules are rather looked unlatered. 4. Six days after the irradiation, most severe alterations were seen. Many intracellular canaliculi (or secretion figures), quanta of cytoplasm containing secretion antecedants, severely irregular luminal border, and again contrasting density of secretory granules showing tigroid spots or dense rims were noted. And myoepithelial degenerations were observed not uncommonly. 5. Irregular densities of secretory granules were interpreted as abnormal components of protein or carbohydrate portion are synthesized or abnormally metabolized under severe X-irradiation. 6. Myoepithelial degeneration and related alteration of nerve endings, etc., were suggested as the other causes of xerostomia following X-irradiation. 7. It is requested that radiation doses should be arranged, considering in mind not only the sensitivity of acinar cells but also the myoepithelial and neural functions.
