This study aimed to determine eco-friendly factors on the aspects of library service, materials provided or handled by the library, and programs including educational programs. Furthermore, it was setup to perform a trial evaluation for the eco-friendliness of the library based on the determined evaluation standards by this study. Results are as follows; First, regarding the question of 'Do employees of the library think that establishment of green libraries is necessary?', the employees of the libraries responded yes by 65.52%, but only 4.6% responded that it would not be necessary. Second, in analyzing the most important evaluation areas of green libraries according to the opinions of the libraries' employees, they were ranked in order: the indoor environment, energy and prevention of environmental pollution, and material and resource areas. Third, 11 areas were determined to evaluate the level of greening in the libraries; the highest averages were scored 510 for the area of energy and prevention of environmental pollution, 415 for the area of library resource, and 320 for the area of indoor environment. Last, the libraries were graded based on actual data according to the results to measure the level of greening, two libraries were graded as Diamond, the highest grade, accounting for 15.39% of all libraries; Gold and Silver grades accounted for another 15.39%, together five Certified graded libraries accounted for 38.46%, which was the highest rate among the libraries. Any library scoring less than 20% when compared to the full score was graded as Non-certified, and one library, which scored 15.06% fell into this category. The results of this study set up to serve as basic data for the direction of development for green libraries in our country, as well as reference for the employees of libraries in constructing or remodeling library buildings, establishing service infrastructure, providing information service, and planning library duties in an eco-friendly way.

Most of the Korean watersheds are mountaineous and consist of various soil types and land uses And seldom watersheds are found to have long term hydrologic records. The SNUA, a hydrologic watershed model was developed to meet the unique characteristics of Korean watershed and simulate the storm hydrographs from a small mountaineous watershed. Also the applicability of the model was tested by comparing the simulated storm hydrographs and the observed from Dochuk watershed, Gwangjugun, Kyunggido The conclusions obtained in this study could be summarized as follows ; 1. The model includes the simulation of interception, evaporation and infiltration for land surface hydrologic cycle on the single storm basis and the flow routing features for both overland and channel systems. 2. Net rainfall is estimated from the continuous computation of water balance at the surface of interception storage accounting for the rainfall intensities and the evaporation losses at each time step. 3. Excess rainfall is calculated by the abstraction of infiltration loss estimated by the Green and Ainpt Model from the net rainfall. 4. A momentum equation in the form of kinematic wave representation is solved by the finite differential method to obtain the runoff rate at the exit of the watershed. 5. The developed SNUA Model is a type of distributed and event model that considers the spatial distribution of the watershed parameters and simulates the hydrograph on a single storm basis. 6. The results of verification test show that the simulated peak flows agree with the observed in the occurence time but have relative enors in the range of 5.4-40.6% in various flow rates and also show that the simulated total runoff have 6.9-32% of relative errors against the observed. 7. To improve the applicability of the model, it was thought that more studies like the application test to the other watersheds of various types or the addition of the other hydrologk components describing subsurface storages are needed.

The impact of 1 pound of nitrous oxide ($N_2O$) on warming the atmosphere is almost 310 times that of 1 pound of carbon dioxide. Agricultural soil management is the largest source of $N_2O$ emissions, accounting for about 73% of total $N_2O$ emissions. This study was conducted to evaluate the nitrous oxide emission in the cultivation of soybean during the first year of No-tillage (NT) and Conventional-tillage (CT) practices, under the various conditions such as different kinds of fertilizers, soil temperature, and moisture level. In the experiment, we set CT and NT treatments into 4 different groups - control treatments (no fertilization), green manure treatments, chemical fertilizer treatments and organic manure treatments. In the case of chemical fertilizer treatments, $N_2O$ emission of NT treatment was 7.78 to 22.59% lower than CT treatment. In organic manure treatment, $N_2O$ emission of NT treatment was 6.62% higher than CT treatment in August. But In July and September, $N_2O$ emission of NT treatment was 9.50% 28.38% lower than CT treatment, respectively. Soil temperature was correlated with $N_2O$ emission positively. In the future, continued long-term research on influence of various environmental factors on the generation of $N_2O$ and the economic value of no-till farming is required.

The purpose of this study is to derive institutional improvement methods for promoting the Damaged Area Restoration Project in greenbelts. The current status of greenbelts in Gyeonggi-do, where greenbelts are extensively distributed was analyzed, and the relevant laws and regulations were reviewed to suggest measures to promote the restoration project. The area of damaged areas within greenbelts in Gyeonggi-do was 6,121,024 m², accounting for about 0.52% of the total area of greenbelts, and more than 80% was found to be located in Namyangju (55.49%), Hanam (16.48%), and Siheung (8.68%). Various measures to improve the policy were examined as follows: reducing the minimum size of the restoration project area; adjusting baseline of recognizing range of damaged areas; introducing the right of claim for land sale; allowing long-term unexecuted urban parks to be replaced as alternative sites for parks and green spaces; simplifying administrative procedures; and allowing public participation. All of them are expected to promote the restoration project within greenbelts. In results, when the minimum size of area for the restoration project was reduced from 10,000 m² into 5,000 m², 3,000 m² and 2,000 m², the ratio of the number of combinable lots to the total number of lots increased from 4.4% to 18.8%, 38.8%, and 55.9% respectively in Namyangju. Morever, when the recognizable ranges of the restoration project were extended to the structures obtaining building permit as of March 30, 2016 and obtaining use approvals before December, 2017, the number of applicable lots increased by 5.1% and 9.2% respectively.

With 12 environmental basic facilities (EBF) in Busan, each business place's present situation of the operation of new and renewable energy as well as the feasibility to establish additional systems of utilizing solar energy (photovoltaic power generation system [PPGS] and solar heating system [SHS]) were investigated. Currently, with the environmental basic facilities, the new and renewable energies (such as, waste heat, biogas, PPGS, SHS, and small hydro power) can produce 195 GWh per year as electric power unit. Among the energy sources, except waste heat, biogas (154 GWh/yr) appears as the highest. Next, PPGS is the second most widely used system and produces 5,560 MWh/yr at 11 business places. Through a field survey, it appears that 19 business places of total 27 places at 12 EBFs have good locational conditions and they need an introduction of PPGS. Through it, it is investigated that it would be possible to produce 5,311 MWh/yr and to reduce $2,348tCO_2/yr$. And, it is identified that SHS can be additionally introduced in only 4 EBFs. This can reduce energy cost as much as one ten million won/yr and green-house gas as much as $28tCO_2/yr$. A cost-benefic analysis shows that the use of governmental support or private investment can be the most efficient way, when PPGS and SHS are introduced in EBFs.

We seasonally examined marine macroalgal community structures and ocean environmental characteristics in subtidal zones at five sites on and around Jeju Island, Korea, from February 2013 to November 2015. A total of 186 macroalgal species were identified, including 18 green, 33 brown, and 135 red algae. During the study period, the number of species was highest at Gapado Island (125 species) followed by Bukchon (123 species), Sagye (122 species), Sinheung (122 species) and Sinchang (97 species). Ecklonia cava, Peyssonnelia caulifera, Synarthrophyton chejuense, Corallina aberrans and Corallina crassisima occurred at all study sites and in all seasons. The average annual biomass of seaweed was $1,125.10g\;wet\;wt./m^2$ and ranged from $899.77g/m^2$ at Sinheung to $1,452.00g/m^2$ at Gapado. A brown alga E. cava was the most dominant species, accounting for 49.84% ($560.78g/m^2$) of the total seaweed biomass. Subdominant species were C. aberrans and C. crassissima, comprising 6.83% ($76.79g/m^2$) and 5.98% ($67.28g/m^2$) of total biomass, respectively. Cluster analysis revealed three distinct groups: the Sagye/Sinheung group (group A), the Bukchon/Sinchang group (group B), and the Gapado group (group C), indicating significantdifferences in macroalgal communities between sites.
