식물사회네트워크란 식물사회를 이해하기 위한 기존의 식물사회학적 방법과 사회과학에서 최근에 주목받고 있는 사회연결 망 분석 방법을 접목하여 식물사회연결망을 시각화하고 분석하는 것을 말한다. 구축 및 분석 과정은 조사구 설정 및 출현 수종 조사, 종간결합분석, 소시오그램 작성, 네트워크 구조 및 중심성 분석 순으로 진행된다. 식물사회네트워크를 구축하기 위해 본 연구는 해안식생과 내륙식생을 동시에 볼 수 있는 부산광역시를 중심으로 다양한 상관우점식생이 포함되도록 708개 조사구를 설치하여 출현 수종을 조사하였다. 조사 결과, 출현한 수종은 모두 195종이었으며, 상록수 42종, 낙엽수 151종, 반상록수 2종으로 나탔으며, 전체 출현수종을 중심으로 종간결합분석을 실시하였다. 종간결합 분석 결과, 친화종수는 사스레피 나무(47종), 마삭줄(46종), 감태나무(44종), 팥배나무(44종), 광나무(41종) 순으로 나타났으며, 이를 바탕으로 gephi 0.9.2. program을 활용하여 소시오그램을 작성하였다. 작성된 소시오그램은 해안에서 주로 출현하는 그룹과 그렇지 않은 그룹으로 나뉘어져 있어 부산광역시 산림식생의 지리적 분포특성을 반영하고 있었다. 네트워크 구조를 분석한 결과, 1,709개의 연결선 (link)이 나타났고, 한 수종과 종간결합을 갖는 종수의 평균은 약 17.5개였다. 밀도는 0.09, 지름은 5, 평균 경로거리는 2.268로 분석되었는데, 사회과학분야의 네트워크 특성과 정밀한 비교 분석을 위해 앞으로 다양한 식물사회네트워크 구축이 진행되어야 할 것으로 판단되었다. 부산광역시 식물사회네트워크에서는 사스레피나무, 감태나무, 광나무, 마삭줄 등이 중심성 이 높은 것으로 나타났다.

This study was conducted in order to investigate the effects that the difference of planting time by a method of cultivation in the non-heated greenhouse and the open field with spring planting had on growth and yield. With regard to the tested variety of Momordica charantia, variety ‘Dragon’ (Japan Yae 農藝) was selected. And 3 treatments on March 20, April 5 and April 20 for the greenhouse cultivation and 3 treatments on April 20, May 5 and May 20 for the open-field cultivation 1 month later than those for the greenhouse cultivation were planted by the randomized complete block design, and 4 secondary vines were trained. In the results of examining 15-day average atmospheric temperature after planting according to the methods of greenhouse and open-field cultivation and planting time, it was shown that there was a tendency for atmospheric temperature inside the greenhouse to decrease as the planting time was moved up. In particular, the average atmospheric temperature was 16.7oC when seedling was planted on April 20 in the open-field cultivation, which was approximately equal to 17.0oC of the average atmospheric temperature when a seedling was planted on March 20 in the greenhouse cultivation. With regard to the date of first harvest by the method of cultivation, it was shown that there was a tendency for the date of first harvest to be earlier in the greenhouse cultivation than in the open-field cultivation, and the date of first harvest was moved up as a seedling was planted earlier for the planting period. The number and weight of harvested fruits per plant showed a tendency which was almost similar to that of total number of harvest days and number of harvests. Thus, the number of fruits was 189 and the weight of fruits was 31,649g in case of the greenhouse cultivation and planting on March 20, which were maximum. In case of planting on the latest planting date : May 20 in the open-field cultivation, the number of fruits was 77 and the weight of fruits was 12,502g, which were at a level of 40% of those of planting on March 20 in the greenhouse cultivation 2 months earlier. The total yield per 10a was 10,228kg in the greenhouse cultivation and was 2.2 times as heavy as 4,607kg in the open-field cultivation with regard to the method of cultivation. For the planting period in the greenhouse cultivation, it was 10,539kg and 10,517kg in planting on March 20 and April 5, which was higher by 9% than 9,629kg in planting on April 20. And in the open-field cultivation, it was 4,785kg in planting on April 20 and 4,872kg in planting on May 5, which was higher by 15~17% than 4,163kg in planting on May 20. Taking the above results into account, it is considered proper to plant Momordica charantia from March 20 to April 5 for the greenhouse cultivation and from April 20 to May 5 or thereabouts when a risk of late frost is gone for the open-field cultivation in southern area.

The early Korean church had experienced rapid growth and revival. What caused this phenomenon? What are its driving forces? Though so far there have been many papers on the quantitative growth of the Korean church, there are almost none which deals with it from the perspective of church planting. Therefore, in this paper, I tried to evaluate the Nevius Plan as a church planting theory that enabled the early Korean church to grow rapidly. As a result of this study, I found that the Nevius Plan as a church planting method has some strengths and weaknesses.The Nevius Plan is positive in that it enhances greatly the spontaneity of believers on the basis of Three-self Principle─self-support, self-governance, and self-propaganda. However, it is not an absolute principle that can unconditionally be applied in every condition. In addition, it is wrong to place the responsibility of evangelism and church planting on only native people. Such interpretation is a distortion of the Nevius Plan. This would be demonstrated by the supportive argument that when considering Adams Evangelistic Fund, the Nevius Plan did not collide with strategic fund supports. When the Nevius Plan based on Three-self Principle was introduced to missionaries in Korea, it was indigenized into a church planting method focused on self-support and self-propaganda. As a church planting theory, it regarded the church as an organic community full of vitality and pursued establishing indigenous churches in their own culture. Three-self Principle functioned as a concrete method for church planting. However, it should not be recognized as an end in itself or an absolute theory, rather it should be applied appropriately in a certain circumstance in which local churches existed. In his writing, John Nevius also agrees that supporting fund should be invested to several ministries such as school, and to hire paid workers in case of need. Therefore, to believe that the Nevius Plan insists on leaving the responsibility of evangelism and church planting to native people without any outer fund, is a distorted interpretation. As the Nevius Plan was applied all over the country, Adams Evangelistic Fund, which had a marked effect on church planting ministry in Taegu area, demonstrates how the Nevius Plan as a indigenous church planting theory could be harmonized with fund support. Three-self Principle is the important foundation for indigenous church planting. The Nevius Plan makes church planting not a humanistic enterprise but a dynamic work led by the Holy Spirit. On the other hand, if funds in the strategic church planting support workers devoted to the Three-self spirit, it will heighten the intensity of effect more than the case of when everything is left to only native people will. It is of course that beneficiaries’ sense of independence is necessary in this case.

본 연구는 일본 고베시 로코아일랜드 완충녹지의 공간기능별 지형구조, 식재개념, 식재구조를 조사분석하여 해안매립도시의 토지이용을 고려한 완충녹지 식재기법 연구 기초자료를 제공하고자 수행하였다. 로코아일랜드(총면적 580ha)는 대규모 완충녹지를 박스형으로 조성하여 외곽부의 항만물류 산업용지와 도시내부 도시기능용지로 구획되었다. 완충녹지 지형구조는 편향마운딩형, 병렬마운딩형, 복합마운딩형이었고, 북쪽의 녹지폭은 50m, 동쪽의 녹지폭은 8~32m, 서쪽의 녹지폭은 37.5m, 경사도는 18~25˚, 성토고는 2~15m이었다. 공간기능별 재개념은 해안측 사면부는 경관식재와 완충식재, 도시내부는 경관식재와 녹음식재를 적용하였다. 북측 완충녹지 식재구조 조사결과, 종가시나무, 녹나무, 후박나무, 녹보리똥나무 등 난온대 상록활엽수를 식재하였고, 100mm2단위의 종수 및 식재밀도는 최대 교목 9종 22주, 아교목 9종 15주, 관목 3종 67주로 전 층위 14종 104주이었다. 녹피율은 교목층 69~139%, 아교목층 26~38%, 관목층 6~7%, 전 층위 101~184%, 녹지용적계수는 교목층 1.40~3.12m3/m2, 아교목층 0.43~0.55m3/m2, 관목층 0.06m3/m2, 전 층위 1.89~3.73m3/m2이었다.

본 실험에서는 국화의 재배방법에 따라 즉, 적심재배방법과 정식시기에 따른 국화 '진바'의 생육과 절화의 상품성과 재배기간의 차이에 미치는 영향에 대하여 알아보고자 하였다. 실험 결과 무적심 재배의 경우 화아 분화 돌입에 필요한 충분한 영양생장기간을 확보하는데 비해, 적심재배의 경우는 충분한 영양 생장기간을 확보하지 못하였다. 화아분화 유기 12주 후의 무적심 재배 개화율은 95%를 상회하였으나 적심재배는 95% 이하로 나타났다. 무적심재배구는 정식시기에 관계없이 3등급상품 이상의 절화가 100% 생산되었으나 적심재배는 첫째주 정식구에서 84.7%로 아주 낮았고 둘째주 정식구는 64.3%, 셋째주 정식구는 18.8%, 넷째주 정식구는 2.6%로 적심재배구의 절화 상품성이 아주 좋지 못하였다. 무적심재배구의 절화품질이 제일 좋지 못한 넷째주 정식구와 적심재배구의 절화품질이 제일 좋은 첫째주 정식구를 비교하면 절화의 품질은 무적심재 배 넷째주 정식구가 좋았고 재배기간도 38일을 단축시킬 수 있었다. 이와 같은 절화국화 무적심재배는 적심 재배에 비하여 재배기간 단축과 품질향상이 가능하므로 경영비 절감과 소득향상이 가능한 재배법으로 판단되었다.

돌나물의 노지 가을삽식을 위하여, 줄기의 삽수 부위(상부, 중부, 하부) 및 삽식 방법(점파, 조파 산파)에 따른 월동전후 생육특성을 조사하였다. 삽수부위에 따른 삽목후 40일째의 월동전 생육은 상부 삽수에서 초장, 근장, 줄기수, 지경수, 지상부 생체중 및 건물중 등에서 유의하게 높았으며, 월동후 개화전(May 10th) 생육은 개체당 줄기수, m2당 지상부 생체중 및 건물중에서 하부 삽수보다 유의한 증가를 보였다. 삽식 방법에 따른 삽목후 40일째의 월동전 생육은 점파(10×10cm)가 조파나 산파보다 양호하였고, m2당 지상부 생체중 및 건물중도 점파〉산파〉조파 순으로 높았다. 월동후 생육(May 10th)은 개체당 줄기수, m2당 생체중 및 건물중에서 점파가 조파보다 유의하게 증가하였다. 돌나물의 가을 노지 삽식은 줄기 상부의 삽수를 이용하는 것이 월동 전후 생육 및 수량성에 유리하였으며, 삽식방법은 점파에서의 수량성이 가장 양호하였으나, 생력화를 위해서는 월동후 생체중에서 점파와 유의한 차이를 보이지 않은 혼파방법이 바람직할 것으로 기대되었다.

본 연구는 서울시에 조성된 아파트단지내 녹지를 대상으로 식재개념, 식재밀도, 식재유형 및 패턴 등 배식특성을 조사.분석하여 개선방안을 제시하고자 실시하였다. 대상지는 아파트단지 녹지면적이 크게 달라지는 시기의 대표대상지인 1978년에 준공된 강서구 화곡주공아파트(2단지)(용적률:99%), 1983년에 준공되 강남구 삼익그린아파트(2차)(용적률:175%), 1992년에 준공된 강서구 동신대아아파트(용적률:225%)를 선정하였으며 녹지를 전면녹지, 측면녹지, 후면녹지로 구분하였다. 대상지의 녹지유형별 식재개념은 경관식재로만 이루어져 시기에 따른 차이는 없었으며 식재종에 있어서도 외래종 조경수목이 주를 이루어 녹지공간별 차이는 없었다. 아파트단지의 식재밀도은 교목 및 아교목층 0.0~0.2주/m2로 관목층의 식재밀도가 부족하였으나 조성시기에 따른 식재밀도의 차이는 없었다. 층위구조는 교목.아교목층과 관목층 수목이 각각 다른 위치에 평면적으로 식재된 단층구조이었으며 녹지공간과 관계없이 독립식재, 열식재, 부등변삼각식재가 주로 활용되었다. 아파트 단지내 녹지는 공가별 식재개념에 따라 식재종, 식재밀도, 층위구조, 식재패턴이 다양하게 이루어져야 하므로 식재개념에 차별화시키기 위하여 전면녹지는 시각적 차폐와 미적인 기능, 후면녹지는 녹지량 증지 및 생태적 개념, 측면녹지는 녹지량을 증진을 주된 목적으로 조성할 것을 제안하였다.

Background : Cynanchum wilfordii is a perennial species of climbing vine belonging to the family Asclepiadaceae. Cynanchum wilfordii native to Korea has been cultivated and used for medicine with tuber root. Direct seeding and seedling transplanting and tuber root seed (below ∅10 ㎜) planting have been performed for cultivation. This experiment was carried out to investigate growth and yield characteristics of Cynanchum wilfordii according to planting method. Methods and Results : Direct-seeding and tuber root seed (TRS) planting were performed in early April and seedling transplanting with seedling grown for 40 days was performed in early may. TRS size was 2 – 3 ㎝ in length and 10 ㎜ and 20 ㎜ in diameter respectively. Seedling establishment rate was similar as 97.3% - 99.0% in all treatments. Vine length, branch number, node number and chlorophyll content were not significantly different in all treatments. Stem diameter, leaf length, and leaf width were higher in TRS planting. Main root number was more as 4.5 - 4.3 in seedling planting and TRS planting (∅20 ㎜) respectively but first lateral root number was not significantly different in all treatments. Root diameter was thicker as 23.3 ㎜ in TRS planting (∅20 ㎜). Total yield in TRS planting (∅20 ㎜) was higher as 1,041 ㎏/10 a, 25% increased compared to 830 ㎏/10 a of direct seeding and with higher commercial yield rate of 75.7%. Conclusion : It was considered that higher total yield and commercial yield in TRS planting (∅20 ㎜) was resulted from bigger size of stem diameter, leaf length, and leaf width and bigger main root size related to root yield and commercial value.

Background : For the GAP standard cultivation, weed occurrence pattern was investigated by planting density and mulching method of Bupleurum falcatum L. Methods and Results : Vinyl and rice straw were used for mulching. The planting density were 10, 20, and 30 cm, and the spacing between plants were 5 ㎝. The amount of weed emergence were examined twice at the end of July and at the end of September. The degree of importance was based on the Braun-Branquet’s dominance value distinction criterion. As a result, the kind of total weeds emerged during the cultivation of Bupleurum falcatum L. were identified as 20 species in 10 families. Amount of weed’s occurrence were the highest in rice straw covering after 10 × 5 ㎝ sowing, and it were lowest in vinyl mulching after 30 × 5 ㎝ sowing. The frequency of weed emergence was highest with 10 species of 8 families in rice straw mulching treatment. On the other hand, the treatment with the least emergence frequency of weeds was 30 × 5 ㎝ sowing after vinyl mulching, and weeds of 7 species of 6 families appeared. In the second survey in September, weeds of 15 species in 9 families were identified in the test field. The amount of weed’s occurrence were the highest in rice straw mulching after 10 × 5 ㎝ sowing, and it were the least in the case of vinyl mulching after 30 × 5 ㎝ sowing. The frequency of emergence of weeds was highest in rice straw mulching after 20 × 5 ㎝ sowing, and the kind of weeds were 11 species of 8 families. The treatment of the lowest emergence frequency of weeds was 30 × 5 ㎝ sowing after vinyl mulching. Three kinds of weeds occurred. Conclusion : From the above results, it is expected that we can suppress the weed occurrence at the planting density of 30 × 5 ㎝ after vinyl mulching at the sowing of Bupleurum falcatum L.

This study was performed to identify the effect of fertilizer application and planting method on growth and yield of 'Seolhyang' strawberry during seedling raising. According to the concentration of fertilizer applied, the height of daughter plants was the highest at an EC of 0.8 dS·m-1. Leaf number and crown diameter were greatest at an EC of 0.6-0.8 dS·m-1. In the first measurement, root number was highest in non-fertilizer application, while root weight was heaviest in non-fertilizer application and EC 0.4 dS·m-1. The higher the concentration of fertilizer applied as culture media, the lower the growth rate. Thirty days after planting on the main field, plant height and number of new leaf were highest at an EC of 0.8 dS·m-1. However, no significant difference was found in leaf length and width and chlorophyll content according to fertilizer application. Marketable yield of 25 g or higher was greatest in EC 0.6 dS·m-1. In contrast, no significance was found in total marketable yield at an EC of 0.4-0.8 dS·m-1. Aconsistent pattern was exhibited in the growth of 1-5 harvesting flower clusters according to planting method. The length of leaf and flower cluster was short and chlorophyll content was low, when bed soil was removed 100% in harvesting of the first flower cluster. In all treatment, leaf length was shortened until harvesting of the second and third flower cluster, but rapidly lengthened in harvesting of the third and fourth flower clusters. Moreover, the length of flower cluster had a increasing tendency from harvesting of the third flower cluster. However, chlorophyll content was reduced continuously until harvesting of the fifth flower cluster, and was lowest in harvesting of the fourth flower cluster without removal of bed soil. Total yield was greatest in treatment of crown removal in bed soil between November and May. Late marketable yield between March and May was highest in treatment of 100% bed soil removal, followed by treatment of crown removal. Marketable yield of 25 g or higher was greatest in treatment of crown removal between December and February, while greatest in treatment of 100% bed soil removal between March and May.
