山地流城에 있어서의 土石移動은 滯留過程과 移動過程으로 구분되며, 과거로 부터의 변화과정을 반영하고 있는 현재의 지표면의 특성을 분석하기 위하여는 원인과 결과를 분명히 하여야 한다. 여기서 원인이란 단위시간 안에서 유역특성을 구성하는 요인인 地形, 地質, 氣候, 植生, 土地利用 등을 의미하며, 결과란 流域안에서 발생하고 있는 山沙汰, 땅밀림, 河床變動 등을 말한다. 본 연구는 조사대상지인 山地急流河川에 있어서 상기 원인중 地形(河川徵地形)과 植生(同齡林分)을 분석하여 결과로서 존재하는 河床變動을 해석하는데 필요한 기초자료를 얻고저 하였다. 그 결과 河床堆積地의 침입수목의 年輪解析으로부터 河床變動에 대한 空間的(堆積高)·時間的(滯留期間) 分布에 대한 객관적인 자료를 얻을 수 있었다. 따라서 이를 기초로하여 流域間 또는 區間間의 地表變動의 特性을 時·空間的으로 해석하므로서 보다 객관적인 防災對策을 수립할 수 있을 것이다. Based on the topographical and vegetational indicators on sediment movement of Yongcheon River, the movement occurence years were estimated. 1. The cross sectional shapes of deposits in torrential stream are stepped and even-aged forests tend to be established on each step. 2. Generally the older the forest age is, the higher the height of step from the lowest base tend to become. 3. The ages of trees indicate the year when deposition occured, and so may be useful as plant indicator to get chronological information.

21세기에 들어 在來木本植物을 이용한 비탈면 綠化가 이용되기 시작되고 있으므로 그 발전방향을 예측하기 위해 綠化의 기본적인 개념과 綠化에 대한 주역주민의 인식을 정리하여 보았다. 조사결과, 지역주민은 綠化의 필요성과 在來木本植物을 이용한 工法을 충분히 인식하고 있었으나, 外來種의 도입에 대해서는 대부분의 주민이 부정적이었다. 따라서 앞으로는 비탈면 綠化의 多面性을 추구해야 하며, 在來 木本植物의 도입이 곤란한 장소에는 在來 雜草類의 이용을 추진해야 할 것이다. 또한 비탈면에 시공하고 있는 金網은 人爲的 災害를 유인할 가능성이 있으므로 시정할 필요가 있다. 결론적으로 비탈면 綠化는 단기적으로는 비탈면의 物理的 安定과 生態的 安定에, 중·장기적으로는 地球環境의 改善과 向上에 기여해야 할 것이다. The twenty-first century was entered and began to show the extent where revegetation of the face of slopes using the native woody plant was nationwide at last. Then, future revegetation of the face of slopes was considered on the basis of them in order to attempt the development of this direction, while the recognition for fundamental matter of the revegetation and revegetation of t h e regional inhabitant was arranged this time. The regional inhabitant sufficiently understood t h e necessity of the revegetation, and the method using the native woody plant had sufficiently been recognized, and the high evaluation was given in the method. In the other, the major inhabitant questioned it for introducing the exotic species. I t was proposed that the utilization of native weeds should be advanced by the pursuit of many facets of the revegetation of the face of the slopes based on these in future in the place where the introduction of the native woody plant is difficult. And, the method for stretching the wire netting for the face of slopes indicated the necessity of the urgent review, because the artificial disaster might be caused. As a conclusion, the goal of the revegetation of the face of slopes confirmed that it was ecologically stable short-terminable face of slopes physically and connects it with the medium and long term for improvement and improvement of global environment, and it indicated the importance of the revegetation of the face of slopes.

강릉시 시범 공설묘지 조성사업은 경사 30˚ 의 표고차가 심한 산지를 절 · 성토하여 계단식 묘역단을 조성하는 공사로 수직고 15m이상의 대절토 및 성토부가 산재하고 있다. 특히 묘역단장후 주변 유입수 및 표면 유출수에 의한 비탈면 붕괴, 묘역단 유실 등의 피해가 발생할 경우 보수 또는 보강이 사실상 어려운 실정이며, 사회적 여론으로 확대될 가능성이 크므로 비탈면 보호에 필요한 녹화공법을 검토하였다. 구체적인 연구내용으로는 설계도면 및 현장답사를 통한 문제 비탈면 추출, 비탈면의 물리적 특성과 식생의 생육상황 파악, 비탈면 주변부의 식생조사와 유용식생 선발, 비탈면의 토양조건 분석 및 비탈면 토사의 기본물성 조사 등이며, 이를 기초로 하여 비탈면 현황 및 문제점을 파악하고, 그 대안을 제시하였다. The construction of a public cemetery in Kangnung city includes terraced graveyard with cutting or banking in mountain which has severe altitude differences with a slope of 30˚. Therefore, there are scattered cutting and banking sections with vertical height more than 15m. Especially, if the slope failure or the loss of a graveyard happens after graveyard establishment due to surface flow and inflow around, it is difficult to repair, causing serious public censure. Accordingly. revegetation works were examined that need protection of slope. The specific content of the study was the selection of slopes requiring special care through blueprint and field investigation the measurement of the physical property of slope and the situation of vegetative growth, the investigation of vegetation in slopes and the selection of vegetation, and the analysis of soil condition of slopes and the physical condition of slope sediment. On the basis of investigations some alternatives were proposed.Key words: public cemetery, slope protection works, revegetation works

This study was conducted to find out the suitable gradient and length of the slope from the landslide of banking slope and cutting slope caused by rainfall. The survey was carried out on forest road built in 1986. And the period of survey was from June, 1989 to August, 1989 after dividing the forest road into A and B. The survey plots consisted of the 12 banking slopes and 6 cutting slopes. The results obtained from the study were summarized as follows; 1. The rate of landslide appeared 75% in A forest road, 50% in B forest road, and then the average 67% in A and B forest road. But the value of landslide showed considerably low. 2. Because of landslide chiefly occuring on banking slope of 36˚∼38˚ and on cutting slope of 42˚∼ 43˚, it is suitable to decide the banking slope and cutting slope below each 36˚and 40˚. 3. Landslide was the same on banking slopes through the length of slope. The best suitable length of slope is below 4m in cutting slope.

전건수,김유승,하재성,박준용,서정오 大韓成形外科學會 1993 Archives of Plastic Surgery Vol.20 No.3

Pressure sore is an area of ischemic tissue loss resulting from prolonged or often repeated pressure, usually over a bony prominence of body. Recently, the prevalence of pressure sore is major clinical problem, due to the increased number of patients with spinal cord injuries or longterm comatous patient after traffic, industrial accidents. The surgical principles in the treatment of pressure sores are total excision of the ulcer, scartissue, bursae, complete removal of all infected bone with recontouring of bony prominences to alleviate discrete pressure points and resurfacing and padding of the defects with healthy and well vascularized tissues. The sacral sore is the most common site for the development of pressure sore in Korea. We had experienced 14 cases who had received surgical treatments for sacral sores with transverse lumbosacral back flap. We obtained the following conclusions. Advantages 1)It is quick and easy procedure 2)The flap elevation itself is relatively bloodless 3)The donor defect is in a non-weight-bearing area 4)Muscle is not sacrified(possibly of importance in the ambulatory patient) 5)Surgical options are preserved in cases of recurrence(the flap itself may be reelevated and inset in some cases of recurrence) Disadvantages 1)It is lacking the bulky padding afforded by alternative musculocutaneous flaps 2)The vascularity of the flap tip is empirically less dependable than that of a musculocutaneous flap 3)The donor defect is large, cannot usually be closed primarily, and may prove of cosmetic concern
