Green Infrastructure(GI) is suggested to recover urban water circulation system as a newly conceptual alternative methodology by Korean landscape field in recent years. In this context, the study considers the essential meaning of GI. The methodology of this study is literature review with 47 published papers which were peer-reviewed in international journals in the recent 5 years. These papers were collected from online database and academic archives. The main analysis targets are definition sentences about GI. The each sentences were interpreted by semantic structure between verbs and objects in the definition sentences. As the results, it figured out 5 aims('Provide', 'Improve', 'Produce', 'Conserve', 'Reduce'), 4 objects('Humanistic', 'Environmental', 'Ecological', 'Hydrological') and 3 spaces('Object space', 'Technically available spaces', 'Object or technically available spaces'). The '5 aims' connected with the elements of '4 objects' based on the '3 spaces'. The elements was connected to the '5 aims' via single form or 2~3 forms of the essential meaning networks of GI. The study provides 83 meaning networks to use landscape architecture planning and urban planning.

Objectives :The Korean Medical concept Gak-Gi(脚氣) is understood as being identical to Beriberi and Vitamin B1 deficiency, without the necessary investigation that is required in such identification. Therefore this study aims to systematically compare these two concepts for thorough investigation. Methods : Research was carried out in two directions. First, the cause, symptoms, treatment principles of Gak-Gi(脚氣) in the medical texts were analyzed. Second, the process of the Beriberi theory development and its identification with Gak-Gi(脚氣), medical information on Beriberi, and the basis of various diseases that have been linked to Gak-Gi(脚氣) were studied. Results of the two directions were used to compare Gak-Gi(脚氣) and Beriberi. Results : Gak-Gi(脚氣) and Beriberi overlap in many aspects. However, unlike Beriberi which is understood as nutrient deficiency essentially, Gak-Gi(脚氣) can be caused by exterior pathogens such as wind toxin, while its different manifestations and treatment principles cannot be fully explained by nutrient deficiency. Conclusions : Gak-Gi(脚氣) could be understood as a type of syndrome in which causes and symptoms are connected, where symptoms start in the legs, moving upwards. It cannot be identified with Beriberi, which has been interpreted as a single disease.

Background/Aims Although functional abdominal pain disorders (FAPDs) are common in children, the accurate pathogenesis of FAPDs is not known yet. Micro-inflammation, particularly tissue eosinophilia of gastrointestinal (GI) tract, has been suggested as the pathophysiology observed in several GI disorders. We aimed to evaluate eosinophilic infiltration throughout the entire GI tract in children with FAPDs, compared to those with inflammatory bowel diseases (IBD) and to normal reference values. Methods We included 56 children with FAPDs, 52 children with Crohn's disease, and 23 children with ulcerative colitis. All subjects underwent esophagogastroduodenoscopic and colonoscopic examination with biopsies. Tissue eosinophil counts were assessed in 10 regions throughout the GI tract. Results Eosinophil counts of the gastric antrum, duodenum, terminal ileum, cecum, and ascending colon were significantly higher in children with FAPDs compared to normal reference values. Eosinophil counts of the stomach and the entire colon were observed to be significantly higher in children with IBD than in those with FAPDs. Even after selecting macroscopically uninvolved GI segments on endoscopy in children with IBD, eosinophil counts of the gastric body, cecum, descending colon, sigmoid colon, and the rectum were also significantly higher in children with IBD than those with FAPDs. Conclusions Significantly high eosinophil counts of the stomach and colon were observed in the order of IBD, followed by FAPDs, and normal controls, regardless of endoscopically detected macroscopic IBD lesions in children. This suggests some contribution of GI tract eosinophils in the intrinsic pathogenesis of FAPDs in children.

The existing mobility management schemes do not fully support the next generation network, which is composed of IP-based core network and various access networks. Currently, ETRI has been developing the AIMS (Access Independent Mobility Service) system which satisfies the ITU-T requirements of mobility management in the next generation network. The AIMS system is designed to provide a mobile host with a fast and reliable mobility service among heterogeneous access networks. Recently, many user devices have multiple communication interfaces, e.g., 3G and WLAN, and thus they can make two or more network connections at the same time. In this paper, we design a scheme of flow mobility, i.e., the movement of selected data flows from one access technology to another, to be applied in the AIMS system, and verify the proposed scheme through the NS-3 simulation study. From the simulation results, we can know that the proposed flow mobility scheme can utilize the network resource efficiently in the heterogeneous mobile networks.

This paper aims at the comparative study of practicing Buddhism and Taoism related to "life gate". The term "life gate", as a physiological entity of disputed morphological identity, first appears in The Inner Canon where it refers to the eyes. Reference to a "life gate" as an internal organ body first appears in The Classic of Difficult Issues which states, "The two kidneys are not both kidneys' The left one is the kidney, and the right is the life gate." Successive scholars refers to life gate as a gi point of Taoists.. The question of the life gate invited little discussion until the Myeong and Cheong Dynasty, when various different theories were put forward. Especially Jin Sa-taek says "life gate" is the governor of the twelve place in the human body, throwing light on the meaning of it. Not that life gate denotes a local point, it does a system of life gate. Generally speaking, life gate designates cinnabar field. I think that the human body produces essence by way of life gate. That is, the human body is unified by the system of life gate. Life gate is not only the source of infusing the engine of the human body with vital energy but also as well as gi-point.

This paper aims to identify the spatial concentrations and linkage properties of industrial clusters in the Chungbuk Province region in Korea using a three-step approach, which is composed of the cluster index, Getis-Ord's $Gi^*$, and qualitative input-output analysis. The results of the study reveal: a) what industrial sectors are concentrated and where they are; b) where the spatially interdependent industries are; and c) how the industrial sectors of the identified clusters in different locations are vertically interconnected. In addition, the degree of strength of the interindustry linkages between industrial clusters are assessed. Based on the findings, some plausible industrial policies are suggested.

Recently spatial modeling that combined GIS and Cellular Automata(CA) which are based on dynamic process modeling has been discussed and investigated. However, CA-based spatial modeling in previous research only provides the general modeling framework and environment, but lacks of providing simulation or transition rules for modeling. This study aims to propose a methodology for extracting spatial relation rules using GIS and Knowledge Discovery in Database(KDD) methods. This new methodology has great potentials to improve CA-based spatial modeling and is expected to be applied into several examples including urban growth simulation modeling.
