The architectural site exists in the context of the surrounding environment as the background of architectural design, and the architecture exists in the connection between the site and the surrounding environment therefore, the plan of the building starts from the analysis of the site, and its consequences too meaning can be found in the relation with the surrounding environment. Ironically, however, there are no direct papers describing site analysis with this meaning. Therefore, this paper categorizes the site analysis items around the four environments of Land, Water, Fire, and Wind that constitute the environment of the ecosystem, furthermore, in order to apply the result of the fusion information to the architectural design by synthesizing the organic correlation between the inside and the surrounding environment, i created the '9sectors system', which is a combination of 'horizontal 3 and vertical 3' to provide a more rational and efficient architectural plan. Through the progress of the project using this system, it is considered that it is a more applicable method of the site analysis data than the existing site analysis method.

From the anodic peak currents of cyclic voltammograms for Ag(I)/Ag(II) couple obtained with the variation of nitric acid concentration, Ag(I) concentration and solution temperature at a Pt electrode in concentrated nitric acid solutions, the diffusion coefficients of Ag(I) ion were evaluated to estimate the limiting current density of Ag(II)-mediated electrochemical oxidation (MEO) process, which has been effectively used for the complete destruction of hazardous organic materials. The results showed that, due to the water decomposition reaction which occurred simultaneously with the Ag(I) ion oxidation, background subtractions for the cyclic voltammograms were required to estimate the correct peak currents. The empirical relationship for the diffusion coefficient of Ag(I) was suggested as a function of solution viscosity and temperature.

This study examined the wearing conditions of working clothes of shipbuilding industry workers according to the working environmental factors and working process features. It was also investigated the relationship between the wearing sense of working clothes and the overall comfort according to work processes. In the working process of shipbuilding industry, the process of fitting, welding, grinding and painting were chosen by considering work environmental factors, disaster types, hazardous materials, work process features, working clothes and safety equipments of each work categorized. The workers of fitting process usually wore the standard working clothes, while more than 60% of the workers of welding, grinding and painting wore the specialized protective clothes. The hazardous work environmental factors such as noise, heavy dust, high temperature and noxious fumes affected to the workers of fitting, welding and grinding. However, the workers of painting were greatly damaged by organic solvent. The dissatisfaction with the wearing performance of working clothes was highly shown in the sweat absorbency, moisture permeability and body protection. In respect of the correlation between the overall comfort and the wearing sense of working clothes, the satisfaction was decreased in orders of movement comfort> sensual comfort> physiological comfort.

The adsorption behavior of aromatic acids on Amberlite XAD-4 resin was investigated by measuring the distribution coefficient by batch method. The adsorption of solutes on XAD-4 was affected by the several factors such as, analyte concentration, the pH of solution and concentration of pairing ion. The enhanced adsorption of solutes on XAD-4 in the presence of tetraalkylammonium salt as an ion pairing reagent, referred to as ion interaction, was suggested to follow a double layer model where the pairing ion occupies a primary layer at the adsorbent while the solute anion and other anions in the system comlpete for the secondary layer. Therefore, the ability of an ion pairing reagent to enhance solute adsorption depended significantly on the type and concentration of counter-ion and co-anion accompanying the ion pairing reagent or salt used for ionic strength control. In addition, a good linear relationship between the logarithm of capacity factors measured by batch and elution method as a function of the concentration of ion pairing reagent and methanol can be used to predict the retention in elution method on the basis of capacity factors measured by batch method.

In order to achieve the purpose of treatment for patients by a doctor, the instruction explanation obligation, which means that he should give patients the description in more details to prepare for postoperative sequelae or complications, is common with the advice explanation obligation as a doctor should ex-plain some information to patients. Since the advice explanation obligation is the benefit and protection of the law for self determination right, but the instruction explanation obligation is one for the integrity of body and life, one can be distinct from the other. Judgments giving the instruction on the concept of instruction explanation obligation, specific methods of implementation and a range of compensation for damage are recently being made by courts at all levels including the Supreme Court. It is the time to systematize them. The contents which have been mainly discussed so far include the essence of above mentioned instruction explanation obligation. However, when the tendency of practice is considered, the efforts are required to admit the organic relevance between instruction explanation obligation and advice explanation obligation and to explain the relationship without any contradiction. For whereabouts of li-ability of proof, patients theoretically demonstrate the failure to implement it. However, when the theoretical consistency is maintained, it is likely to fail the intent to recognize the instruction explanation obligation and it may ask patients to prove something impossible to be proven. Thus, these things should be considered. Moreover, as the instruction explanation obligation is associated with medicine instruction obligation of a pharmacist and the coverage is being extended, it is the time to require the systematic study on the theoretical limit.

In this study, to evaluate the applicability of ORP and pH as process control parameters for an intermittent aeration process, a 200L/d bench-scale plant was installed and operated for 90 days. It was fed with synthetic wastewater which contained $COD_{Cr}$ : 400mg/L, TN : 40mg/L and TP : 7mg/L. ORP & pH were measured on-line and compared with the variation of nutrient concentrations. As the results, both of the ORP and pH were able to monitor successfully nitrification and denitrification. Bending-points on the ORP curve and peak points on the pH curve corresponded to the termination of nitrification and denitrification. For P uptake and release, pH was the best indicator for performance evaluation. The aerobic pH apex was appeared when P uptake was accomplished and there was a relationship between the P release and pH variation. But the pH curve needed filtering because there were many noises on it. In this study, the shape of the ORP & pH curves were varied as the operating conditions such as aeration rates and organic loads were changed. It allowed the operating states of biological systems to be effectively evaluated. If it is properly managed to show the bending points and peak points clearly, the on-line monitoring of ORP & pH will be a reliable and effective technique for process control of intermittent aeration processes.

This study suggests a conceptualization model of 'cultural inclusiveness' organically connected to social inclusiveness, by expanding the implications of urban inclusiveness to the domain and relationship. Based on the process of necessity of relation, connection of space, and execution of act, the cultural inclusiveness could be connected to the formation of organic/learning relation, the creation of openness focusing on public space, and the practice of diverse subjects. Concretely, the concept of cultural inclusiveness is applied to the case of 'Hongdae-ap'. The recent Hongdae-ap is showing the value of coexistence such as the establishment of environment that could protect the diversity of individual subjects and groups(artists, residents, government officials, students, cultural activists, citizens, tourists, and etc.), the formation of public space such as 'Hongdae-up playground', 'pedestrian-friendly street', and 'Gyeongui-Line book street', social network service & horizontal network, and access.

Tropical forests play a critical role in mitigating climate change, and therefore, an accurate and precise estimation of tropical forest carbon (C) is needed. However, there are many uncertainties associated with C stock estimation in a tropical forest, mainly due to its large variations in biomass. Hence, we quantified C stocks in an intact lowland mixed dipterocarp forest (MDF) in Brunei, and investigated variations in biomass and topography. Tree, deadwood, and soil C stocks were estimated by using the allometric equation method, the line intersect method, and the sampling method, respectively. Understory vegetation and litter were also sampled. We then analyzed spatial variations in tree and deadwood biomass in relation to topography. The total C stock was 321.4 Mg C $ha^{-1}$, and living biomass, dead organic matter, and soil C stocks accounted for 67%, 11%, and 23%, respectively, of the total. The results reveal that there was a relatively high C stock, even compared to other tropical forests, and that there was no significant relationship between biomass and topography. Our results provide useful reference data and a greater understanding of biomass variations in lowland MDFs, which could be used for greenhouse gas emission-reduction projects.

The prediction of landfill settlement is very important for managing land properly, especially in small national land like Korea. It is difficult to express settlement using the consolidation theory because biochemical decomposition is main reason of settlement, and organic materials in landfill are decomposed far long time. In this study, LFG (Landfill Gas) generation characteristics are studied to find long-term settlement analysing model landfills. Two lysimeters are made; one is leachate recycled, and the other is not leachate recycled. The relationship between gas generation and settlement is analysed as a function of time. A mathematical gas generation model is suggested to predict long-term settlement due to biodegradation, and correction coefficient is recommended for long term settlement through model tests. The leachate recirculation system is more effective to accelerate landfill settlement. The appropriate coefficients of gas correction for non-recycled leachate model are 1.4 and 1.7 for recycled system from tests showing 22% of acceleration.
