The purpose of this study was to discuss how traditional construction practices could be applied to school buildings. The spatial arrangement and constituents of Seoweon and Hyanggyo buildings were analyzed, and the spatial arrangement and ground plans of current schools were analyzed as well. As a result, it's found that how the characteristics of traditional architecture should be reflected in today's school design is one of critical matters that need an immediate attention. Based on the case study, there are some suggestions about the application of traditional construction techniques to school buildings: (1) The link between internal and external spaces should be stressed. The type of spatial configuration the could ensure nature accessibility is required. (2) The use of environment-friendly materials is recommended, and classrooms should be arranged in a way to let them function as multipurpose educational spaces. (3) It's not advisable to construct school buildings according to the sung-Confucianistic construction techniques of traditional educational institutions, but there should evidently be a change in tasteless school buildings, They should be built in small size and in consideration of harmony with nature and ecosystem, and boarding schools should be constructed in a more careful and discreet manner.

Although human beings have been able to lead the affluent life owing to industrialization and development of science and technology, as the result of this, the nature has be destroyed, energy consumption has been accelerated, urban area has got wide and the nature has got narrow. In the face of such critical situations, concerns have been aroused to environment. In order to minimize the environment destruction and accompany the aesthetic, efficient and advantage methods, environmental marketing has been introduced to indoor. Environmental marketing is the marketing that minimizes the reverse function so as to obtain the satisfactory result, and it is still in the stage of fundamental investigation. stage. As the concept and type of environmental marketing have not been established yet for interior design, environmental marketing currently applied to indoor space is classified Into three types in this study. Through the four types of environmental marketing, which are the introduction of natural elements to indoor space, the use of eco-friendly materials and the use of sustainable materials, renovation it is intend to derive the environmental marketing strategy and present the sequence of strategy establishment and desirable direction in environmental marketing.

The green craze has hit all the world lately. The green revolution which means immense changes for sustainable development under the new environment-economy system is foretelling that we should have new angle to the environment and economy. This paper is about the development of the model and indicators for construction of ECO(Energy Circulating Organic)-Village which is the green growth option of local community. This model is composed of three concepts - SPDC (about procedural methodology of Model), Virtuous Circle (about functional relationships of three requisites), Network (about spatial relationships between communities) - and evaluation indicators. Environment, tourism, industry (Energy & Organic Agriculture) are set as the three requisites for green growth of local community. Nations of the world plunge into the green war which is silent, general, sweeping changes. We can not win this war with the existing thinking system and policy. We need revolutionary changes reconsidering of environmental value and sustainable development strategy of the region. Each of us should go through the changes and this work would be the one among those efforts.

Fermentation of palm oil mill effluent (POME) produces biohydrogen in a mixture at a specific set condition. This research was conducted to purify the produced mixed biohydrogen via absorption and membrane techniques. Three different solvents, methyl ethanolamine (MEA), ammonia ($NH_3$) and potassium hydroxide (KOH) solutions, were used in absorption technique. The highest $H_2$ purity was found using 1M MEA solution with 5.0 ml/s feed mixed gas flow rate at 60 minutes absorption time. Meanwhile, the purified biohydrogen using a polysulfone membrane had the highest $H_2$ purity at 2~3 bar operating pressure. Upon testing with proton exchange membrane fuel cell (PEMFC), the highest current and power produced at 100% $H_2$ were 1.66 A and 8.1 W, while the lowest were produced at 50/50 vol% $H_2/CO_2$ (0.32 A and 0.49 W). These results proved that both purification techniques have significant potential for $H_2$ purification efficiency.

Submetering electricity consumption data enables more detail input of end use components, such as lighting, plug, HVAC, and occupancy in building energy modeling. However, such an modeling efforts and results are rarely tried and published in terms of the estimation accuracy of electricity demand. In this research, actual submetering data obtained from a university building is analyzed and provided for building energy modeling practice. As alternative modeling cases, conventional modeling method (Case-1), using reference schedule per building usage, and main metering data based modeling method (Case-2) are established. Detail efforts are added to derive prototypical schedules from the metered data by introducing variability index. The simulation results revealed that Case-1 showed the largest error as we can expect. And Case-2 showed comparative error relative to Case-3 in terms of total electricity estimation. But Case-2 showed about two times larger error in CV (RMSE) in lighting energy demand due to lack of End Use consumption information.

"Environmentally Sound and Sustainable Development (ESSD)" is a key word in recent years. The construction industry, have put a great influence on ergonomic and sustainable environment. Recently, "green building certifications", such as Indoor Air Quality (IAQ) and eco-friendly material regulation have been established. With this regard, new construction and aged-housing remodeling projects are required to meet these certification criteria. Multi-housing residents have great concern on eco-product, since many cases are reported that Sick Building Syndrome is caused by toxic substance from building materials. Aged-housing remodeling project is very unique in that building residents are selected prior to design phase. Therefore, the analysis of resident's need for building materials in aged-housing remodeling is relatively easy compared to new building construction. As such, it is very important to analyze their preferences for eco-friendly materials prior to project execution. The purpose of this study is to find the needs of residents and priority of their needs. Based on their needs and priority, this paper provides a new strategy in using environment-friendly materials and maximizing their satisfaction level when aged housing remodeling is constructed. In addition, this paper provide new criteria in selecting new developed environmental materials in remodeling projects for the purpose of improving the safety and health level in construction industry.

Since the great acceleration, the emergence of the sustainable development concept amid the conflict between economic growth and the preservation of the natural environment is at a time when an efficient land-environmental plan integration system is needed to achieve a smart balance between development and conservation. Although preceding studies have been conducted domestically and internationally on various aspects, the operating system has not been implemented effectively. In this study, the policy concept of environmental policy integration, the current status of integrated management of land-environmental plans in South Korea, and related literature studies were reviewed to derive overall complementary points. In addition, the review was carried out by reorganizing the domestic urban planning legal-based system and the environmental legal-based system according to the same hierarchy to promote an effective integration system, and in foreign cases, the establishment of spatial and environmental plans in Germany and Japan was typically considered to derive implications for the establishment of an efficient interconnection system for the integrated management of domestic land-environmental plans in the future.

The concept of 'Cleaner Production(CP)' and various activities aiming at promoting CP are investigated along with the applicabilities of CP to marine environment. Although the conventional approaches dealing with the marine pollutions can be absorbed in CP, the whole activities of Production and conservation in the ocean must be projected into a new Paradigm, 'Sustainable Development.' Renewable energy is the first key to a complete CP and the ocean can provide us with the clew. In order to introduce CP system more effectively to marine environment opinion collection, environment monitoring, problem identification, resolution proposition, state-of-the-art evaluation, policy development, communication, education and public information are to be Planned and followed up systematically KOSMEE is believed to be a good structure to stand at the center of the upcoming CP activities in the ocean.

The National Forest Inventory (NFI) is important for providing fundamental data for basic forest planning and the establishment of forest policies for the purpose of implementing sustainable forest management. The purpose of this study is to present the development of Korea's NFI including legal basis, sampling design, and measured variables and to review the usage of NFI data. The survey methods and forestry statistics among the Unites States, Canada, Japan, China, and European countries were briefly compared. Total 140 publications utilizing NFI data between 2008 and 2015 were categorized with 15 subjects. Korea has conducted the NFI 6 times since 1971, but only the $6^{th}$ NFI is comparable with the fifth, the previous NFI, because the permanent sampling plots have been shared between the periods. The Korean Forestry Statistics contains only half as many variables as that of advanced countries in Forestry. More researches were needed to improve consistent measurement of diverse variables through implementation of advanced technologies. Additional data for Forest Health Monitoring since the NFI $6^{th}$ must be under quality control which will be an essential part of the inventories for providing the chronological change of forest health.

Soil quality assessment is an important tool for environmental management in an agricultural field. It can be used to evaluate the health of the soils and to establish the basis for sustainable urban agriculture and soil management. For this study, the chemical properties of the soils used for urban agriculture were examined. Results of the soil analysis for chemical properties were applied to soil quality assessment system, which is composed of principal component analysis, application to scoring function and derivation of soil quality index (SQI). Soil pH, electrical conductivity (EC), organic matter (OM), total nitrogen (T-N) were determined for minimum data set (MDS) according to principal component analysis. Based on the results of scoring for four indicators (pH, EC, OM, T-N), soil pH was the indicator that needs the most urgent management. Results of SQI derivation showed that many of the urban farms appeared to be insufficient score in comprehensive soil quality assessment. In conclusion, soil management practices based on scores derived from soil chemical indicators need to be carried out to maintain sustainable urban agricultural soil environment and to provide easy-to-understand information to urban farmers.
