The objective of this study were to offer a basis data for application of management of forest resources through grasping of species composition by layer of forest vegetation in the Mt. Geumwon recreational forest. The tree and subtree layer consisted of 27 and 44 species in Mt. Geumwon recreational forest respectively. The importance value of Quercus mongolica (57.1) and Q. serrata (40.4) were highest in the tree layer and that of Acer pseudo-sieboldianum (43.4) was highest in the subtree layer, respectively. The shrub and herb layer was composed of 71 and 69 species, respectively. The value of species diversity ranged from 1.0391 to 1.5403. Evenness ranged from 0.7259 to 0.8320. Dominance was 0.2741 at tree layer, 0.2440 at subtree layer, 0.1680 at shrub layer, and 0.1702 at herb layer, which showed that Mt. Geumwon recreational forest is dominated by a large number of species at all layer. The result of forest vegetation in Mt. Geumwon recreational forest may be utilized as a basic data for application of reasonable ecological management of forest resources.

본 연구는 멸종위기 아고산수종 구상나무 잔존집단 복원을 위해서 묘목처리 및 입지환경이 구상나무묘목 초기생장에 미치는 영향을 구명하고자 수행하였다. 연구대상지는 경상남도 금원산으로 해발 1,300 m 이상 능선부(1입지)와 구상나무 잔존집단(2입지)을 선정하였다. 식재한 구상나무 실생묘는 지리산 5개 개체에서 종자를 채취하여 2014년도 파종한 1~5묘 1,350본을 이용하였다. 2019년 5월 연구대상지의 조릿대를 제거 후 무처리, 분해포트, 균근균 접종 실생묘를 9개 구역으로 나누어 3반복씩 입지별 0.15 ha, 4,500 본/ha 밀도로 식재하였다. 식재 후 2019년 5월부터 8월까지 입지별 기상데이터를 수집하였고 묘목의 생존율, 수고, 1년지 생장량 및 근원경을 측정하였다. 환경분석 결과 1입지(88.2%, $42.8umole{\cdot}m^{-2}{\cdot}s^{-1}$)가 2입지(84.5%, $29.4umole{\cdot}m^{-2}{\cdot}s^{-1}$)에 비해 대기습도와 광량이 높게 나타났다. 구상나무 실생묘의 생존율은 모든 입지에서 100%로 나타났다. 입지별 생장특성 분석 결과 1입지가 수고 17.3 cm, 1년지 생장 4.72 cm 및 근원경 6.20 mm로 2입지(19.0 cm, 3.88 cm, 5.31 mm)에 비해 양호한 것으로 나타났다. 묘목 처리에 따른 분석 결과 무처리와 분해포트 묘목이 모든 입지에서 초기 생장이 양호하였고 균근균 접종 처리는 초기에는 비교적 낮은 생장특성이 나타났다. 결과적으로 대기습도와 광량이 높은 환경 조건이 구상나무 묘목의 초기 생장에 긍정적인 영향을 주었으며 묘목 처리에 따른 생장특성은 지속적인 모니터링이 필요한 것으로 나타났다.

This experiment was conducted to investigate current situation and plant grouping by light and watering of mingled several cacti and succulents in a pot. The main 11 cacti are consist of Myrtillocactus geometrizans (Mart.) Cons., Gymnocalycium mihanovichii var. friedrichii Werd., Marginatocereus marginatus(DC.) Backbg., Eriocactus leninghausii (Hge. Jr.) Backbg, Notocactus scopa (Spreng.) Berg., Lobivia nealeana Backbg., Mammillaria elongata var. intertexta (DC.) SD., Pseudoespostoa (Vp1.) Backbg., Mammillaria albilanata Backbg., Mammillaria klissingiana Bod. and Espostoa lanata (HBK.) Br. & R. The main 10 succulents are Kalanchoe thyrsifolia Harv., Portulacaria afra var. foliis-variegatis Jacobs., Crassula perforata Thunbg., Echeveria pulvinata Rose, Aeonium arboreum cv. atropurpureum., Echeveria lauii Moran & J. Meyran, Pachypodium lamerei Drake, Sedum rubrotinctum cv. Aurora Boom., Aloe mitriformis Mill., and Euphorbia coerulescens Haw. The cacti were native to Mexico, Brazil, Peru, Paraguay, Ecuador, etc. The sucullents were native to Mexico, Africa, Gran Canaria, Madagascar, etc. Most of all the cacti and sucullents in the experiment are growing well under full sun or light shade, however Portulacaria afra var. foliis-variegatis Jacobs, and Sedum rubrotinctum cv. Aurora Boom. did not influenced by light. And all the plants require a little or moderate watering. Thus, planting by similar required water and light, when growing in a pot of several cacti and succulents, might be decreased the rate of death causing by their different plant physiology.

멜론(Cucumis melo L.)은 서아프리카, 중근동, 인도, 중국등이 원산지로 알려져 있으며 유럽형 넷트멜론과 동양계 무넷트멜론으로 크게 분류되고 있다. 우리나라는 삼국시대부터 동양계멜론인 참외가 주로 재배되어 왔으나, 최근 국민소득수준의 향상과 더불어 고급 과채류에 대한 선호도가 높아짐에 따라 넷트 멜론의 재배가 증가되고 있는 추세이다. (중략)

To provide basic information for wildlife management, we investigated the distribution and ecology of wild mice in Mt. Keumwon recreational forests. The trapped wild mice were a total of 4 species such as Eothenomys regulus, Apodemus speciosus peninsulae, Apodemus agarius, and Crocidura suaveolens. A total of 79 individuals from four species were trapped. Number of Eothenomys regulus was the highest as 41 individuals followed by Apodemus speciosus peninsulae of 31 individuals, Apodemus agarius of 4 individuals, and Crocidura suaveolens of 4 individuals. Depending on forest type, 51 individuals were captured in broad-leaved forests, whereas 28 individuals were captured in coniferous forests. Average weight of the trapped Eothenomys regulus, Apodemus speciosus peninsulae, Apodemus agarius, and Crocidura suaveolens was 37.13 g, 36.29 g, 31.25 g, and 15 g, respectively. Among the trapped wild mice, vole which has the largest head and ears were Eothenomys regulus and vole which has the longest tail was Apodemus speciosus peninsulae and Apodemus agarius (p<0.5). This study might be valuable to control and predict some damages related to wild mice in Mt. Keumwon for protecting forest trees.

Conflict minerals refer to minerals mined in conditions of armed conflict, especially as in the eastern provinces of the Democratic Republic of the Congo. The common conflict minerals are cassiterite, wolframite, coltan(columbite-tantalite ore), and gold, which are mined and extracted from the Eastern Congo. These minerals are essentially used in the manufacture of a variety of devices, including consumer electronics. To end the violent conflict in the Democratic Republic of the Congo (DRC) and in surrounding countries, it is necessary to block the supply route of conflict minerals which has been partially financed by the exploitation and trade of conflict minerals. The Dodd-Frank Wall Street Reform and Consumer Protection Act, passed into law in July 2010 and it contains requirements that U.S. companies report to the Securities and Exchange Commission(SEC) on the origin of conflict minerals and show due diligence of OECD. The goal of the act is to cut direct and indirect funding of armed groups engaged in conflict.

The variations of monthly mean sea levels along the coast of Korea anre studied graphic and harmonic methods with the data from 9 tides stations and compared with the variations of atmospheric pressure and the changes in density of sea water measured near some of the stations. The monthly mean sea level generally rises in Summer to Autumn, and falls in Winter to Spring and its range is from 20 cm to 50 cm. The variation of monthly mean sea level is of annual type, having one maximum and one minimum. The semi-range of annual components is 10.5 cm at Pusan and increases to the north in the west coast, to 20.8 cm at Inchon. It's phase is, on the whole, similar for the entire coast with about 210 (middle of August), except at Inchon, 200 . The variation of monthly mean sea level is mainly isostatic, or caused by those of sea water density and atmospheric pressure. Especially, the steric effect is predominant on the south- east coast around Pusan. However, in shallow long bays and estuaries on the west coast, the river runoff effect as well as local wind effect is also considerable. Magnitudes of annual variations at each stations are not constant, but widely variable from year to year. On the east and south coast, especially at Ulneungdo and Pusan the variations are large, which seem to be connected with the shifting of main current axes or current patterns in the offing.
