In acidosis associated with mineral acids, acide- mia per se, results in predictable increases in serum K^+ concentration. In acidosis associated with nonmineral organic acids, serum K^+ concen- tration usually remains within the normal range in uncomplicated cases. The mechanism of this di- ffering effect of mineral and organic acidemias on transmembrane movement of K^+ remains undefined. We observed that serum K^+ was increased after ingestion of p-fluoroethylacetate 6.0gm for sucide.

Unsteady flow in a natural river which meanders through a wide flood plain is complicated by large differences in hydraulic resistance and cross sectional geometry of the river channel and the floodplain. The unsteady flow is further complicated by the tendency for a portion of the flow to short-circuit along the more direct route afforded by the flood plain rather than following the longer route along the meandering channel. A mathmetical model for routing floods in meandering river with floodplains is presented. The one-dimensional equations modified such that the flow in the meandering channel and floodplain are identified separately. The floodplain model has been used to simulate flow in an idealized meandering river with a flood plain. Flood peak attenuation and travel time are found to increase as flood-plain roughness and width increase and as channel sinuosity decrease. Attenuation increase and travel time decreases as the flood plain flow increases.

The purpose of this paper is to demonstrate major factors influencing regional informatization. In order to present the region information elements by employing the factor analysis in the study, they have been divided into the three catagories such as the generation of information, the distribution of information, and the consumption of information. On the basis of the empirical analysis, the following result was derived. Followed by the factors of information distribution and information consumption, major elements in the field of information production are most important in regional informatization. Therefore, it is meaningful to recognize that strategic efforts to provide information-producing facilities such as telecommunicating infrastructures as well as to support information industries realize balanced regional informatization.

우리나라 복합역사의 현황과 과제

박재홍 水原大學校 2014 論文集 Vol.28 No.-

SAccording to the huge scale of the urban growth and expansion in Seoul since 1970, the railway stations have been developed to the civil railway station based on the private investment. There are two purposes of the paper. First, the study introduces the current status and the development process of the civil railway stations. Secondly, it predicts the direction of developing them on the basis of the current development paradigm of the railway stations. Based on the analysis of the current status and the development process of the civil railway stations, it is found out that most of the civil railway stations in Seoul continue deficit operation. Due to the long period of developing time and lots of land-use restrictions associated with the civil railway stations, the private investment does not want to engage in the development of the civil station any more recently. Thus, It is essential for balancing between the public regulations and the private revenues by allowing land-use deregulation of the civil railway stations Finally, as a policy implication, the result of the study emphasizes that the current civil railway station will be developed to the composite railway station by inviting the public investment as well as the private funds. Therefore, regulation reform should be accompanied by the paradigm shift of railway station development in the future.

As cathode materials of LiMn2O4-based lithium-ion secondary batteries, Li(Mn1-$\delta$M$\delta$)2O4 (M=Ni and Co, $\delta$=0, 0.05, 0.1 and 0.2) materials which Co and Ni are substituted for Mn, were syntehsized by the solid state reaction at 80$0^{\circ}C$ for 48 hours. No second phases were formed in Li(Mn1-$\delta$M$\delta$)2O4 system with substitution of Co. However, substitution of Ni caued to form a second phase of NiO when its composition exceeded over 0.2 of $\delta$ in Li(Mn1-$\delta$M$\delta$)2O4. As the results of charging-discharging test, the maximum capacity of Li(Mn1-$\delta$M$\delta$)2O4 appeared in $\delta$=0.1 for both Co and Ni. Also, Li(Mn1-$\delta$M$\delta$)2O4 electrode showed higher capacity and better cycle performance than LiMn2O4.

2010년 한 해 동안 국내에서 발생한 교통사고 는 226,878건으로써, 5,505명이 사망한 것으로 보고되었다. 이러한 수치는 2009년에 비해 5.7%가 감소한 것으로 분석되지만, (도로교통공단, 2011) 자동차 1만대당 사망자 수로 비교 했을때, OECD 평균(1.3명)보다 2배(2.6명) 가까이 높게 나타난 다. 교통사고 감소를 위한 노력은 정부 및 도로관 리기관에 특히 요구되며, 이러한 노력의 일부로써, 도로관리기관에서는 정기적인 도로안전점검과 사 고 잦은 구간을 대상으로 도로안전진단 등을 실시 한다.

The purpose of this paper is to present the introduction of development right of lands which are restricted to develop by the government for public interests in Korea. Since most of foreign countries adopt the policy to compensate the regulation of landuse currently, it is urgent for us to develop the policy to make up the loss to landowners due to the regulation. On the basis of research, it is more appropriate to implement TDR(Transfer of Development Right) in Korea which is popular in U.S. It is also recognized that although it is the optimal way to revise the urban plnning law to implement TDR in the ling run, it is also possible to apply TDR to local restricted area by regional governments in the short run.

소아에서 경피 내시경하 위루술의 임상적 고찰

박재홍,최병호,최광해,김재영 대한소화기내시경학회 2005 Clinical Endoscopy Vol.31 No.5

Background/Aims: Percutaneous endoscopic gastrostomy (PEG) is a simple, safe and rapid method for the placement of a feeding gastrostomy tube and it is a well- established mean of providing enteral nutrition. Although it is frequently used in adults, there is limited experience for this procedure in children. Methods: Twenty five procedures of PEG in 23 patients were performed in four institutions located in Youngnam province. We retrospectively reviewed our experiences of PEG. Results: Fourteen males and nine females were included and their mean age was 5.7 4.1 years. The patients aged 1 to 6 years accounted for about a half the subjects. The underlying diseases of the patients were CNS disorders in all except one who was suffering with a neuromuscular disorder. The main reason for PEG was swallowing difficulty and the associated complications of the patients. Nasogastric tube feeding was the most common method of nutritional support before the procedures. The most common complication of PEG placement was wound infection. The patients' nutritional status after PEG placement was satisfactorily improved. The indwelling time of PEG tube was over 6 months in 2 of 3 patients and the tube was switched for a new one after a year. Removal of the tubes by using percutaneous traction was done in 2 of 3 patients. Conclusions: The PEG is a safe, easy to perform, and reliable technique to support enteral nutrition in children. 목적: 경피 내시경하 위루술(percutaneous endoscopic gastrostomy, PEG)은 입으로 먹을 수 없는 환자에서 장기간 경장 영양을 하기에 가장 효과적인 방법으로 소아에서 시행한 PEG의 경험을 분석하였다. 대상 및 방법: 1995년 1월부터 2002년 7월까지 영남 지역 4개 병원에서 PEG를 하였던 환자들의 임상 소견에 대해 후향적 조사를 하였다. 결과: 총 23명의 환자에게 25회의 PEG를 시행하였다. 남아가 14명, 여아가 9명이었으며, 평균 연령은 5.7±4.1세였고, 2~6세가 약 절반을 차지하였다. 기저 질환은 근 질환 1예를 제외하고 모두 중추 신경계 질환이었다. 주된 적응증은 연하곤란과 동반된 합병증이었고, 83%에서 시술 전 장기간 비위관 영양을 하였다. PEG 시술 시 또는 유치 기간 중에 경미한 합병증들이 발생하였고, 창상 감염이 24%로 가장 많았다. PEG 유치 후 대부분의 환자에서 적절한 체중 증가가 있었다. 2/3 환자에서 6개월 이상 PEG를 유치하였고, 관을 교체한 경우는 2/3의 환자가 1년 뒤에 복벽에서 관을 견인하여 제거하였고, 나머지는 내시경을 통하여 올가미로 제거하였다. 결론: 소아에서 PEG는 간단하고 안전하며, 적절한 영양 공급을 보장할 수 있는 방법이다.

A 19-year-old girl with typical features of acromegaly, duration of which was thought to be above 10 years, presented with dyspnea. After serial studies, dilated cardiomyopathy and critical stenosis of left anterior descending coronary artery were demonstrated. Brain MRI revealed the following changes: the pituitary gland was enlarged and its upper margin was upwardly convex; severe cerebral atrophy and multiple signs of vascular abnormalities were present. Cerebral angiographic studies demonstrated the presence of complete occlusion of left carotid artery and severe stenosis of right carotid artery with the formation of collateral networks of vessels. The patient was thus diagnosed as having moyamoya disease that was thought to be congenital according to her past histories. Her cardiac function was slightly improved after percutaneous transluminal coronary angioplasty. Operation for the pituitary lesion and moyamoya disease was not performed due to poor general condition, but serum growth hormone concentration was adequately suppressed after octreotide therapy. We consider that this is a very rare case of acromegaly associated with moyamoya disease, coronary arterial disease and dilated cardiomyopathy.(Korean J Med 58:227-233, 2000)
