The purpose of this study was to provide basic data for the systematic management of external landscaping spaces by analyzing the characteristics of changes in planting trees for about 50 years from 1976 to Ojukheon in Gangneung. Information on past planting species was confirmed based on the landscape plan of the Ojukheon Cleanup Site in 1976 and the current status plan of the Ojukheon Tree in 2000, and analyzed in overlap with the results of field surveys. From 1976 to 2023, a total of 18 additional species of trees such as Celtis sinensis, Toona sinensis and Lagerstroemia indica were planted or the tree species name was unified, and three species were not identified. It was confirmed that there was a change in the planting species by Aojegag, Main house, Ojukheon, and Munseongsa in terms of traditional landscape space. And the problems were derived regarding species name (correct name and synonym), lack of information on planting and removal, and foreign species planting by period. In the future, it is judged that systematic history management based on the tree management register, including basic planting information on external landscaping spaces in national cultural properties, is urgent.

We divided the planting bale into waterproof layer, drainage layer and soil layer so at to investigate changes of live load according to species of wood and composition of the base to make rooftops green. The results are follows, 1. As concerning construction and live load for green roof, sheet waterproofing is superior. 2. When materials of drainage are changed crushed gravel into artificial lightweight graval or ferrite, live load of planting bale is decreased about 22% and 25% in order. 3. When ingredients of soil are chased normal sand into volcanic sand, live load of base is decreased about 28%. Especially, when it is changed into ferrite, 54% of live load is decreased. 4. In this study, all live load we concerned excesses the standard about roof live load of office, school and house. Hence, structure has to be concerned thoroughly when making rooftops green. But, we judge that various methods for making rooftops green can be applied if we consider roof garden when we plan new buildings.

본 연구는 임해매립지에서 토양의 화학적 특성을 조사하여 수목식재를 위한 합리적인 토양관리에 관한 자료를 얻고자 수행하였다. 토양조사는 시화매립지의 시흥공단에서 녹지조성 예정지를 중심으로 토지이용별 및 토심별로 실시되었다. 조사지역에서 개흙은 전기전도도와 치환성나트륨 백분율이 높은 염류알칼리성 토양 특징을 갖고있었다. 임해매립지에서 토양 pH 평균값은 7.8~5.7범위이었고, 주거/공단 완충녹지 토양에서 전기전도도와 치환성나트륨 백분율은 각각 3.76Sm-1와 35%로 조사지역 중에 가장 높았다. 토양 50cm 깊이에서 치환성 Na+의 평균함량은 1.76~2.80cmol+/kg으로 조사되었고, 치환성 Na+의 평균함량은 치환성 Ca2+보다는 낮았으나 치환성 Mg2+과 K+보다는 높았다. 토심별 염분농도는 50cm보다 100cm 깊이에서 높게 조사되었으며, 주거/공단 완충녹지는 전토심에서 염분농도가 수목에 영향을 주기에 충분할 정도로 높았다.

Recently, as the population rapidly increases, food shortages and waste are emerging serious problem. In order to solve this problem, various countries and enterprises are trying research and product development such as a study of consumers' purchasing patterns of food and a development of smart refrigerator using IoT technology. However, the smart refrigerators which currently sold have high price issue and another waste due to malfunction and breakage by complicated configurations. In this paper, we proposed a low-cost smart refrigerator system based on IoT for solving the problem and efficient management of ingredients. The system recognizes and registers ingredients through QR code, image recognition, and speech recognition, and can provide various services of the smart refrigerator. In order to improve an accuracy of image recognition, we used a model using a deep learning algorithm and proved that it is possible to register ingredients accurately.

Large trees in the apartment complex are playing an important role to decide the quality of external environment. They are planted with the object of utilizing themselves as a landmark of the complex and enhancing space symbolism. Since planting large trees would require high maintenance costs and generate defect, it would cause decline in quality of external environment. This study researches on large trees in artificial ground of the apartment complex. This study analyzes actual condition of planting and tries to provide improvement direction of planting. In order to conduct this research, three target areas (over R30) and 265 trees are selected. Based on the drawings and specifications this study researches on the plan of landscape design, changes of field design, actual condition of completion, present condition of planting, minimum soil depth of growth and development and types of extra action for soil depth. The result shows that 85% of drawings and specifications for large trees in the apartment complex are deep-rooted tree species. On average large trees with R 35 are planted in artificial ground and there is lack of on average 65cm minimum soil depth of growth and development. Reviewing changes of field design is conducted in such limited size as mainly R30 and R40 and there is no extra plan for lack of soil depth. The plan for securing additional soil depth is done by 85% of mounding. However, since there is only 10% of satisfaction, the inappropriateness in securing additional soil is pointed out. This research also points out that the size of large trees, root characteristics and location-allocation for planting are pivotal factors for securing minimum soil depth of growth and development. This research also provides improvement direction in case of planning planting.

The purpose of this study is to present improvement devices of urban center's green function in the Public Open Space Attached Building(P.O.S.) in Incheon, Korea. Study sites were the P.O.S. of office building(10 place), transportation facility building(3 places), government office building(2 places) that were made up 1994∼2002 and analyzed establishment, using and planting status. And P.O.S.'s planting area structure of Osaka and Kawasaki in Japan that is operating P.O.S. system similar to Korea was compared with study sites of Incheon. P.O.S. of Incheon is not managing as valuable urban center's green and establishing to satisfy legal requirement. The strengthening devices of P.O.S. function are as follows. First, it is desirable that planting area rate of P.O.S. in order to develop small park in urban center is increasing by 40% that is children's park level. Second, it must be conferred about planting basis, tree selection and planting method etc. of P.O.S. with green and park development department at building authorization. Third, by the 'landscape planting standard of plottage' that is becoming planting standard of P.O.S is heightened and must increase quality and amount of green. Fourth, it is required mandatory establishing of sign so that citizens can search easily and utilize of P.O.S. Fifth, legal regulation should be decided to prevent that P.O.S. is used unlike purpose originally.

This study was carried out to obtain reasonable management method of salt-affected soil for ecological restoration in the reclaimed land. Chemical properties of reclaimed soil was investigated base on reclamation years. Ionic acitivity in soil and satruration extract were analyzed to estimate the effect of salt interception by planting ground treatment. The soil porperties of reclaimed land was saline-sodic soil with $11.3dSm^{-1}$ of electrical conductivity, 34.8% of exchangeable sodium percent in first reclamation year. Electrical conductivity, exchangeable sodium and exchangeable chlorine were remarkedly decreased during six years after reclamation but chemical properties of reclaimed soil was unsuitable status for tree growth. Exchangeable sodium perecnt was higher in the neighborhood parks and street tree sites than in the buffer green spaces and was higher in subsoil than in topsoil of profile in all sites. Content of soduim, chloride and sulfate in saturation extract were more than other ions. Content of soduim and chloride were higher in the neighborhood parks and street tree sites than in the buffer green spaces and were higher in subsoil than in topsoil. Content of calcium plus magnesium of soil was higher in the buffer green space than in the neighborhood park and street tree but content of calcium and magnesium in saturation extract were higher, as result from exchangeable sodium, in the neighborhood parks and street tree sites than in the buffer green spaces. Concentration of salt in soil showed the difference with mounding height and planting ground treatment. The lowest concentration of salt appeared in buffer green spaces and street tree sites was the highest. Salt interception by mounding height in the same planting ground treatment was more effective 120cm of mounding height than 70cm of mounding height.
