        산림토양 특성이 집재차량의 주행성에 미치는 영향

        김기원(Ki Weon Kim) 한국산림과학회 1999 한국산림과학회지 Vol.88 No.2

        This study deals with forest soil characteristics and their effects on the trafficability of logging vehicles. The study area is the national experimental forest located in Kwangnung. This site has 20m length and is equally divided by 5 surveying ranges with 4m width, on which a tractor(FIATAGRI) attached with logging boogie can drive in 4 driving types, namely Mime-return unload, 1time-return with load of 780-790㎏ weight of 3 logs, 5 and 10times-return with same load. After one driving type on all surveying ranges, the soil hardness is surveyed 5 times with 3 several type tools, SHM-1 type, lang penetrometer(L-PNTM), and clegg impact soil tester(CIST). A disturbed degree of cover vegetation and sliding conditions of vehicle are also observed. As results, the soil type of the test site was SC by USCS and dry brown forest soil. The cover vegetation is gotten trambled under driving after 3-5 times-return, shrubs leaves are fully fallen and their bark are peeled, and after 10 times-return the cover vegetations were nearly disappeared. The test vehicle has neither slided nor was overthrown. The wheel tracks in the 1-3 ranges, of which unit weight(gd, gt) is high and soil moisture content(MC) is low, were only 1-2㎝ deep, but those in the 4-5 ranges, of which the gd, gt is low and the MC is high, were 5-7㎝ deep. In the soil hardness test, which was established in 5 test ranges by types of driving, the more driving times, the higher the hardness. The soil hardness surveyed by L-PNTM has changed slowly and that surveyed by SHM-1 type has risen sharply. In the ranges with higher specific gravity(Gs), higher unit weight, lower MC and higher liquid limit(LL) and plasticity index(PI) was the soil hardness high and the trafficability was good. In the ranges with opposite conditions, also in the ranges of the lower soil hardness, the trafficability must be not good, because the wheel track may be deep. The results from CIST attached with 4㎏ hammer was not better than expected. So it is recommended to use CIST with 2.5㎏ or 0.5㎏ hammer.

        삼림욕장 설계를 위한 기초연구

        김기원 ( Ki Weon Kim ) 한국산림과학회 1984 한국산림과학회지 Vol.65 No.1

        This study contains the scientific justification of the forest aromatic bath(F.A.B) in the stage of introduction and the general concepts using in the design of the forest aromatic bath ground, especially definition of F.A.B, basic activities and facilities, carrying capacity and criteria deserving much consideration in designing of it. Terpene, the origin of F.A.B appearance, is made clear that it is efficacious in our physical health. The forest (coniferous one) mainly exhales terpene about noon and morning and seasonally spring and summer time. The most influential factor to exhale terpene is the climate one-wind, temperature, sunlight, humidity. Forest canopy and leaves are related to the concentration of terpene in the forest area. The basic activities for F.A.B are mostly static, and so are the facilities. The forest aromatic bath room(F.A.B.R) which a person must be given for F.A.B. is 169㎡, 59 persons per ha. This 169㎡ is the carrying capacity of F.A.B. The sites of F.A.B.G. might better be located around the national and provincial park, mountain torrent, hot spring zone and the waterfronts. Meanwhile, forest management in F.A.B.G should be enforce in order to keep on constantly maintaining the exhalation quantity of terpene.

        임도설계에의 응용을 위한 흙의 토질 역학적 특성

        김기원 ( Ki Weon Kim ) 한국산림과학회 1995 한국산림과학회지 Vol.84 No.2

        This study was carried out to discuss how soils in the area planned for a forest road construction can be mechanically tested and practically applied. For this, 16 soil test samples from 8 plots(2 samples per plot) were used. The major tests are focused on unit weight before and after cut, water content, liquid and plastic limits, sieve and hydrometer analysis etc. The total unit weight(p_t) before and after cut are 1.69g/㎤ and 1.19g/㎤, respectively. Their water contents are 21.0% and 20.5%. The coefficient of uniformity U and coefficient of curvature C obtained from sieve and hydrometer analysis are 125 and 0.42, which mean generally not well graded. On the soil classification by USCS, SM(silty sand or silt - sand mixed soil)is a Key soil, but it seems to be not good for fill material. From the standard proctor test are resulted 1.40±0.065g/㎤ for the unit weight(p) in the nature and 1.88±0.049g/㎤ for the optimum proctor unit weight(ppr) each. With this to say, it is necessary more powerful compaction work at earth filling, with which this soil reachs enough the ppr, and more earth.

        장자(莊子) 소요유(逍遙遊)의 현대적 해석과 산림치유에의 적용에 관한 소고(小考)

        김기원(Kim, Ki Weon) 한국산림휴양복지학회 2017 한국산림휴양학회지 Vol.21 No.1

        본 연구는 장자(莊子)가 주장한 소요유(逍遙遊)의 개념을 분석하여 현대 산림치유에서 의미하는 바를 해석하고 이를 산림치유계획에 적용할 수 있는 방안을 모색한 것이다. 연구를 통해 얻은 주요 내용은 첫째, 소요유의 개념, 둘째, 소요유와 산림치유의 유사점, 셋째, 산림치유활동에서 가장 빈번히 일어나는 활동, 넷째, 소요유와 산림치유와 관련되는 개념들의 비교, 다섯째, 소요유로부터 산림치유에 적용할 수 있는 방안 등이다. 소요유는 현실을 벗어나 고통과 번민이 없는 정신적으로 안정한 무애소통의 세계, 자아실현과 자기초월의 자유의 세계를 일컫는다. 소요유와 산림치유는 세 가지 측면에서 유사함을 발견할 수 있는데, 개념적인 측면, 목적지향적인 측면, 행태적인 측면에서 살펴보았다. 소요유가 추구하는 내용을 산림치유, 의료적 치유, 몽유도원도, 게슈탈트 치료, 명상, 실존적 치료 등과 비교하였다. 비교한 개념들에서 궁극적으로 추구하는 것이 소요유가 지향하는 바와 유사함을 알 수 있었다. 산림치유활동에서 가장 빈번하게 일어나고 목적지향적인 활동은 산책으로 나타났는데 이는 소요유의 거닐다, 노닐다라는 의미와 상통하여 두 용어사이에 매우 긴밀한 관련성이 있음을 발견한다. 이를 근거로 소요유의 개념에서 산림치유에 적용하기에 가장 적합한 활동으로서 숲길걷기를 도출하였다. 숲길걷기는 소요유의 세계로 이끌어야 하므로, 이를 위해 현실세계→전이세계→이상세계의 구도를 지닌 몽유도원도의 공간구도를 적용한 공간계획기법이 필요함을 제시하였다. This study deals with modern interpretation and therapeutic application of Xiaoyoyu(happy wandering) in Zhuangzi. The main results are summarized in concept of Xiaoyoyu, likeness between Xiaoyoyu and forest healing, the most frequent activity in forest healing, comparison of concepts related to Xiaoyoyu and forest healing, application methode of Xiaoyoyu to forest healing. Xiaoyoyu means a condition in which there are no other obstacles and no pains because of isolation from real world, a psychological safety world, a world of self-actualization and self-transcendence, and a condition of an absolute freedom. There are three points of likeness between Xiaoyoyu and forest healing, namely in conceptual aspect, goal-oriented aspect, and behavioral aspect. The pointing content of Xiaoyoyu is compared with forest healing, medical healing, Mongyudowondo, Gestalt therapy, meditation, and existential therapy and it is concluded that they are very close together in pursuit contents. The most frequent activity both in forest healing and forest recreation is walking that can be understood as a motivation or a goal-oriented activity of forest healing or forest recreation. Walking seems to be very close together between Xiaoyoyu and forest healing because Xiaoyoyu itself has a meaning ‘walk leisurely’, ‘take a stroll’, etc. From this point of view, walking forest trail is selected as the most applicable activity to forest healing. Lastly, it is proposed that composition of Mongyudowondo with three steps of real world→middle world→ideal world(Shangri-la) has to be introduced as the spatial planning methode, because walking forest trail has to lead to the world of Xiaoyoyu.

        경제성장-친화적 사회복지정책에 관한 연구

        김기원(Ki Weon Kim) 한국사회정책학회 2002 한국사회정책 Vol.9 No.1

        경제성장 친화적 복지정책은 개별적인 복지정책대안들이 경제성장요인들에 영향을 미쳐서 이들 요인들이 경제를 성장시키는데 직간접적으로 기여할 수 있도록 하는 정책을 말한다. 이는 사회복지와 경제성장이라는 두 마리 토끼를 모두 잡을 수 있는 정책대안이다. The economic development-friendly social welfare policy is designed for welfare policy alternatives to contribute to the economic development directly and indirectly by influencing various economic development factors. It is a kind of policy alternatives which enable us to catch two rabbits, social welfare and economic development.
