최근 중국은 양산항을 개장하여 선사 유치를 위한 다양한 혜택을 제공하고, 일본은 "수퍼중추항만 육성계획“을 세워 항만의 효율성을 바탕으로 비용을 낮추려는 노력을 하고 있다. 또한 선박의 대형화에 의한 중심항만(Hub Port) 위주의 기항과 북중국의 대량 물량 발생지역에 대한 직기항 경향으로 동북아 항만간의 경쟁이 더욱더 치열해 지고 있으며 동북아 역내 피더네트워크 강화의 필요성이 제기되고 있다. 따라서, 본 연구에서는 유럽 피더네트워크 전략 사례를 바탕으로 동북아 피더시장 현황을 파악하고 동북아 피더네트워크 구조를 분석함으로써 동북아 역내 항만 및 선사간의 과당경쟁을 지양하고 서로 Win-Win할 수 있는 터미널의 전략적 활용, 선사간 제휴 확대, 항만간 협력 강화를 위한 구체적인 전략을 제시하였다. Recently, China opened Yangshan port and provides a variety of benefits for shipping companies. Japan plans to reduce logistics costs and improve efficiency through the established "super major ports" project. According to the "hub and spokes" system, the number of direct calls toward North-Chinese ports are increasing. This changing environment has negative effects on the amount of transshipment cargos in Korean ports. In order to make a hub port of a domestic port, it is necessary to develop northeast Asian feeder networks. Therefore, this paper analyzes the structure of northeast Asian feeder networks through the case study of European feeder networks strategy. Finally, we suggests the plans to reinforce feeder networks, which are strategic terminal operation, strategic alliances between shipping companies and port co-operation, for win-win strategy in the competitive northeast Asian market.

Background: Neurotransmitter like substances in the gut have been proposed to contribute to the overall portal systemic encephalopathy (PSE). The source of the ammonia in patients with PSE is mainly the small bowel, as a result of the conversion of glutamine in the diet to glutamate and ammonia. PSE is highly responsive to changes in diet, to antibiotic therapy and to ingestion of nondigestible disaccharides such as lactulose. This study was performed to evaluate the relationship between PSE and oro-cecal transit time. In addition, performed to evaluate the effect of severity, cause, complications of liver cirrhosis on oro-cecal transit time. Methods: Between August 2006 and February 2007, 48 cirrhotic patients consecutively was enrolled in study their oro-cecal transit time after informed consent was obtained. A non-invasive hydrogen breath test was used to study oro-cecal transit time (OCTT). Result: The OCTT were delayed in cirrhotic patients with PSE compared without PSE (123.3 ± 42.7 min vs 170.0 ± 58.3 min, p<0.05). OCTT tended to prolongate further as the damage in the liver got worse, nevertheless the result was statistically meaningless (p<0.111). Neither presence of ascites or cause of PSE had any influence on gastrointestinal transit. Conclusions: Cirrhotic patients with PSE have more delayed OCTT than without PSE. Further research is needed to find out the relationship between OCTT and severity of liver cirrhosis.

This study was carried out in order to estimate the domestic sewage quantities-qualities from combined sewer in Iksan and Hameol. To investigate the domestic sewage quantities-qualities from combined sewer, sample were collected 2 times during this study period at ten points. Flow rate analysis demonstrates a major morning and evening peak between 08:00∼10:00 and 19:00∼22:00, respectively. The concentrations of BOD were in the range of 23∼340㎎/ℓ and 28∼318㎎/ℓ, respectively. The highest concentrations of BOD occurred in the point 1. The concentrations of suspended solids were in the range of 18∼330㎎/ℓ and 13∼85㎎/ℓ, respectively. The pollution loading runoff after a rainy season decreased compared to that made before the rainy season. Comparisions with data for second survey show lower than first survey, from domestic sources, of many dilute water often regarded as having a mainly groundwater origin.

Nonpoint source pollution(NSP) arises due to agriculture activity and it is quite an extensive and complicated problem in order to control and has received a great deal of concern during the recent years, whereas point source are known to originate from an estimated volume of contaminant discharged from a distinguishable source. Extensive research work have been conducted and presented in the past with regard to the various characteristics of watershed on Dong Jin River(DJR), however there are certain drawbacks of existing survey for determining important polluting sources, distribution features of pollutants and estimated load of the organic and nutrients from the creeks. Unfortunately, investigation for loadings originating due to agricultural drainage was not satisfactory, although the regional consideration for DJR across Kim Je Field(KJF) as an agricultural area receives a reasonable source point in the agri-pollution management. Therefore it was necessary to carry out a thorough investigation into the diffuse sources resulting, to form the pollution-developing estimation and to evaluate the output roperties and determining various factors in the generation of non-point pollution. Eventually, this research work would serve as an useful tool for the development of predictive pollution management for DJR. Non-point sources in the present work were classified as municipal non-treated sewage water discharged into the river, loadings through agricultural drainages in the dry/wet field and inadequate treatment of wastewater generated from livestocks. The entire duration of the research work was from December-2001 to July-2002. Site measurement were conducted during various season, in a dry season(December), in rainfall, in seed-sowing time and also collecting data from the rural public organizations related to water management was done and examined and examined during the mid of research work. Similarly, domestic wastewater loadings due to population was based on area unit, as City, Country, Up, Myon, Dong, Ri. The Dong Jin River watershed contains small three Creeks, KoBu(KB), DongJin(DJ, including JeongEup(JE) and ChilBo(CB), WonPyong(WP). It was further divided into 32 sub-watersheds which comprises of further 5,18,9 watersheds in the creeks respectively. The results obtained from research work are presented as follows. Animal productions have marked differences in the rate of pollutant loadings reported in the following sequence: DJ(only CE)>WP>CB>KB, in a case of Korean cow and milk cow. However, it was revealed that WP creek became significantly higher than any other livestocks. According to statistical data for land use, rice field(369.0㎢) and forest(378㎢) have much occupation prior to dry paddies(125.0㎢), residential land(32.0㎢) and others(5.0㎢). Especially, rice fields receives 2.5∼3 times than dry paddies in size.

Plastic shrinkage is likely to occur when the rate of evaporation exceeds the rate at which the bleeding water rises to the surface. Plastic shrinkage clacking occurs at the exposed surfaces of freshly placed concrete due to consolidation of the concrete mass and rapid evaporation of water from the surface. This leads to the tensile stress and concrete surfaces may crack. This so-called shrinkage clacking is a major concern for mortar and concrete, especially for flat structural such as pavement, agricultural roads, slabs for industrial factories and walls. One of the method to reduced the adverse effects of shrinkage cracking is to reinforce concrete with randomly distributed fibers. The contribution of polypropylene fiber to the plastic shrinkage crack reduction potential of concrete and its evaluation are presented in this paper. The results of tests of the polypropylene fiber reinforced concrete were compared with plain concrete. Results indicated that polypropylene fiber reinforcement showed an ability to reduce the total area and maximum crack width significantly(as compared to plain concrete) .

The entire duration of the research work was from December-2000 to July-2002. Site measurement were conducted during various season, in a dry season(December), in rainfall, in seed-sowing time and also collecting data from the rural public organizations related to water management was done and examined during the mid of research work. Generally, the Dong Jin River watershed contains small three Creeks, KoBu, DongJin(including JeongEup and ChilBo, WonPyong). It was further divided into 32 sub-watersheds which comprises of further 5, 18, 9 watersheds in the creeks respectively. Inflow loading to the river was calculated from measurement of general water quality and quantity and these field surveys were made thrice times in agricultural drainage channels, where fertilizers and pesticides leaching from the surface have an direct effect for the deterioration of the several creek and river. Estimation of contaminant loading has been done by using unit loading based on the notification No. 1999 - 143 of the Ministry of Environment. Most of estimated loading data reported during the research work were slightly higher when compared with the notification of the Ministry but they do not have any significant effect. It was assumed that sub-watersheds have considerable field survey loading data, which were affected due to non-point source pollution load as compared to point source. For investigation of surface rainfall ranging from .50㎜ during non-farming or .10 rainfall on the period of farming, BOD loadings in the field during farming showed slightly higher levels in comparison with discharge loadings, T-N also showed the similar trend as discussed earlier.

한국 아동문학 연구 현황과 과제

Korean juvenile literature is characterized by its combination with the children's movement. It is a phenomenon that has been unparalleled in other countries. Most of the first generation of Korean juvenile literature can be said to have been the leaders of the children's movement, the second generation has grown up mostly with the children's movement. Korean juvenile literature was developed as a part of the national movement. This is why the trend of emphasizing enlightenment and reality occurred. It resulted in an imbalance that leaned towards creating a realistic fiction rather than creating a fairy tale or a fantasy. There has been a need for reflective discussion but there has never been enough. The research on Korean juvenile literature is low in quality compared to other general literature. The proof is the fact that the representative masterpieces of Korean juvenile literature are hardly outstanding. The activities of Lee Won-Soo and Lee Oh-Duk in criticism and Lee Jae-Chol in research have been getting attention. Whether it is due to criticism or research, the efforts have born fruit steadily in the literature aimed at the movement based on conscience and sense of mission. It is thinkable that the situation of the research aspect would be improved if the subject of juvenile literature could be established in the curriculum of the universities that train teachers for kindergarten and elementary school.

Gastrointestinal stromal tumor (GIST) is the most common non-epithelial neoplasm arising in the gastrointestinal tract, but this tumor is rarely seen in association with type l neurofibromatosis (NFl) Generally, the majority of GISTs are isolated neoplasm and they are sporadically found in the stomach, but the GISTs in NFl patients are usually multiple and usually found in the small intestine. We report a case of multiple GISTs in the jejunum of a 63-year-old woman diagnosed as NFl accompanied by complication of gastrointestinal bleeding, In this case, Patient had multiple cafe-au lait spots and neurofibroma on skin and had freckling on axilla and groin, and then, we made a diagnosis of NFl. Gastrointestinal bleeding is controlled by resection of multiple GISTs. Generally, only 3-5% of all gastrointestinal bleeding comes from the small bowel. Causes of small intestinal bleeding are angiodysplasia, neoplasm, NSAIDs induced ulcer etc. but, If patients have NFl accompanied by complication of gastrointestinal bleeding, GISTs on small bowel must be considered.
