PMIPv6에서의 위치관리기법을 고려한 이 기종 망간의 Fast Handover 기법 설계 및 평가

심재성,박석천 한국정보처리학회 2012 정보처리학회논문지. 컴퓨터 및 통신시스템 Vol.1 No.3

As the wireless Internet become more widely accessible, variety of Internet services can be used without limitation of location. However, existing mobility management methods such as MIP and PMIP of IETF requires the load of heavy protocol stack on the mobile nodes or the addition of components such as LMA and MAG. In this paper, we proposed the location management technique in the PMIPv6 and Fast Handover technique. according to the moving pattern of the node, the location management technique proposed in order to adjust the paging area dynamically. The Fast Handover technique applied MIH technology and it reduced the handover signal processing time between heterogeneous network. The location management cost in the environment which the node moves in order to evaluate this and handover delay time was calculate. The proposal technique was efficiently more evaluated than PMIPv6 with the smallest 29% and maximum 83%. 무선 인터넷 서비스가 활성화 되면서 현재 많은 사용자들은 공간에 제약 없이 다양한 인터넷 서비스들을 사용할 수 있게 되었다. 그러나 기존의 모바일 노드의 이동성 보장을 위한 IETF의 MIP, PMIP 등과 같은 이동성 관리 기법들은 모바일 노드에 무거운 프로토콜 스택을 탑재하게 하거나 LMA, MAG 등과 같은 신규 구성 요소 추가 등의 문제점을 안고 있다. 이를 위해 본 논문에서는 PMIPv6에서의 위치관리기법과 Fast Handover 기법을 제안하였다. 위치관리기법은 노드의 이동패턴에 따라 페이징 영역을 동적으로 조정하도록 제안하였고, Fast Handover 기법은 MIH 기술을 적용하여 이 기종 네트워크간의 핸드오버 신호 처리 시간을 단축하였다. 이를 평가하기위해 노드가 이동하는 환경에서의 위치관리비용과 핸드오버 지연시간을 계산하였고, 제안기법이 PMIPv6보다 최소 29%, 최대 83% 더 효율적으로 평가되었다.

Nitrogen fertilization and cutting practice were studied on turfgrasses and cover plants to investigate the possibility of maintaining green color during the growing season. Research also involved the effect of the nitrogen on a few morphological characteristics of leaf performance elements which might give an information to coloration and life-span of turf leaves. Treatments in the first experiment undertaken on pot included one N level: 350kgN /ha applied as compound fertilizer in split applications of one-half in mid-May and the rest both in late June and August, and four spring-summer cuts: late May, late June, late July and late August. The soil filled in pot a moderately well-drained sandy loam. In the second experiment(field observation) leaf length and width, inflorescence and flowering, and color performance were also investigated. With nitrogen fertilizer applied on turfs, desirable turf color was maintained during a period of poor coloration in specific seasons such as mid-summer for cool season grasses and late fall for warm season grasses comparing to the non-treatment. However, this was not stimulated by cutting treatment to nitrogen status existed. Cutting effect on coloration was more remarkable in both Korean lawngrass and Manilagrass than in cool season turfgrasses such as Italian rye-grass, perennial ryegrass and tall fescue. Especially down-slide of leaf color in cool season turfgrasses could he detected in mid-summer /early fall season ranging up to mid-September. In early November as well as mid-September, Italian ryegrass, perennial ryegrass and tall fes-cue retained a high level of green color as followed by nitrogen application and cutting treatment, and little detectable variation of leaf color notation between cool season turfgrasses was obtained. However, Korean la'vngrass and Manilagrass failed to retain the green color until early November. Color notations in cool season turfgrasses investigated early November on the final date of the experiment ranged from 5 GY 3/1 to 4/8 in 'Ramultra' Italian ryegrass, 'Reveile' perennial ryegrass and 'Arid' tall fescue, but those in Zoysiagrasses were 7.5 YR 4/8 in Korean lawngrass and 2.5 y 5 /6 in Manilagrass. Life-span of leaves was shorter in Italian ryegrass, perennial ryegrass and tall fescue than in beth Korean lawngrass and Manilagrass with and without nitrogen application. In general, leaves appeared in early May had a long life-span than those appeared in late April or mid-June. Nitrogen application significantly prolonged the green color retaining period in perennial ryegrass, Italian ryegrass, Korean lawngrass and Manilagrass, and this was contrasted with the fact that there was no prolonged life-span of leaves emerging in early May and mid-June in tall fescue. SPAD reading values in 48 turfs and cover plants investigated in the field trial were increasing until late June and again decreasing till September. Increasing trends of reading value could be observed in the middle of October in most of grasses. On the other hand, clovers and reed canarygrasses did not restore their color values even in October. Color differences between inter-varieties, and inter-species occurred during the growing season under the field condition implicated that selection of species and /or cultivars for mixture should be taken into consideration. In Munsell color notation investigated in the final date in the middle of November, 32 cultivars belonged under the category of 5 GY and 10 cultivars under the category of 7.5 GY. This was implying that most of cool season turfs and cover plants grown in the center zone of Korean Peninsula which are able to utilize for landscape use can bear their reasonable green color by early or mid-November when properly managed. The applicable possibilities of SPAD readings and Munsell color notation to determine the color status of turfgrasses and cover plants used in this study were discussed.

본 논문은 한국 전통사찰의 경관현황을 개관하고 조경식물을 통한 가람의 종교적 이미지를 부각시켜 불교신도들의 경건한 수도와 함께 관광적 효과를 한층 거양하기 위한 방안을 모색하고자 산지형 사찰인 낙산사, 부석사 및 불국사를 대상으로 연구를 수행하였다. 이에 얻은 결과를 요약하면 다음과 같다.1. 사찰경 내 수목의 식재현황 및 유형조사대상 사찰에서 석가모니불을 주로 모시는 곳인 대웅전 앞에는 아무런 교.관목이 식재되어 있지 않았다. 극락보전과 무량수전에서는 공통적으로 주목이 식재되어 있었으며 사찰에 따라 매자나무 외 15종이 식재되어 있었다. 또한 불국사의 비로자ㅣ불에서는 백목련을 위시하여 25종의 수목이 식재되어 있음을 볼 수 있었다.한편 낙산사와 불국사의 원통전 및 관음전에는 사철나무 외 26종의 수목이 식재되어 있었다.2. 수목과 사찰 건물과의 연관성 및 산지형 사찰의 교관목 식재모형수목과 각각 건물의 특성과는 특별한 연관성을 발견할 수 없었다. 다만 불교적 의미를 갖는 수종으로서 배롱나무와 불두화가 식재되어 있음이 밝혀졌다. 또한 대체적으로 지역적 특성, 기후 환경과 친화적인 식물이 식재되어 있었으나 수목과 사찰 건물과의 관계를 고려한 배식형식을 찾아보기 어려웠다. 본 조사를 토대로 산지형 사찰에서 교.관목을 식재할 때 활용할 수 있는 모형을 제시하였다. It is the purpose of this study to arrange in ornamental trees and shrubs the planting that leads to an appropriate type of templescape. The study was designed primarily as an examples for each Buddhist temple which desires further decoration with several ornamental plants, doubles the effectiveness of the Sen-Buddhist meditation, and boosts tourists' attraction. To investigate the planting status and type of trees and shrubs in the precincts of Buddhism temples, We close three temples : They are Nagsansa, Boolgoogsa and Booseugsa, which are intermonatane area temples all together. The results investigated were summarized as follows :1. Planting status and pattern in temples Open spaces of the Daewoogjeon in all temples, a main Sanctuaries in temple buildings, where Buddha is enshrined in, we could not find any kind of trees of shrubs to be planted.Muryangsujeon, a symbol of "Future", which can be also found at Boosugsa temple, is living in Western Elysium world and takes mercy on mankind of this life. Taxus cuspidata was planted at this Muryangsujeon, known as an immeasurable bliss building, where an Amitabha is enshrined in.Total 25 species of trees and shrubs were planted around Birozani building of Buddhist temples, Birozani is enshrined at the Birojion of Boollgoogsa temple.The buddhist Goddess of Mercy which is a buddhist saint for pursuit of fortune and blessing to relieve the mankind is enshrined at Wonchonjeon, Daebijeon and Kwaneumjeon which are able to observe at both Boolgoogsa and Nagsnsa temples, where Euonymus japonicus trees including other 26 species could be found in common at both temples.2. Correlation between trees/shrubs and temple buildingsTrees and flowers symbolizing Buddha are often planted as material sources of gardening to decorate : They are Logerstroemia indica as Buddha's flower, Viburmum opulus var. calvescens resembling Buddha's head, Tilia mandshurica producing the beads of rosary, Gardenia jaminoides Ellis with white flower blade and flower of bliss, not flower to this day and Lotus flowering clearly in the pond filling with dirty water which is able to clarifies the world full of crime, infidelity and injustification. Among these Buddhist' plants, however, Logerstroemia indica could be found in all three temples, and Viburmum opulus var. calvescens at both Nagsansa and Boosugsa. Also, Lager stroemia indica was planted at all three temples and Viburmum opulus var. calvescens at both temples of Nagsansa and Boosugsa. Tilia mandshurica and Gardenia jasminoides Ellis were not found in any temples which might become the subject of investigation.In relation of the buildings of each temples as a sanctified space, the planting of trees and shrubs was not considered for the arrangement, templescape architecture or species. And, also, we could not find in the study any special relationship of trees/ shrubs with the characteristics of temples.With the results obtained through precise studies we presented here in this paper newly designed model of templescape in intermane buddhist temple which can be applied for planting and arrangement of trees or/and shrubs. Basic principles of model in mind are:To consider the correlation of the dominant between plants and temple buildings.To plant trees/shrubs for special functions as well as conditions of temple location.To make tree arrangement correlating to Buddhism spirit.To induce environment friendly plants to be planted, suitable to regional conditions.This redecorated model of templescape might be used as a canon of the tree planting and arrangement in the precincts of Buddhism temples.
