  • Saemangeum reclamation project was started in 1991 with the purpose of eco-friendly reclamation, but without clear definition of eco-friendliness. This study was carried out to find out the environmental indicators to define and evaluate the eco-friendliness of Saemangeum project. The methodology to identify the indicators included the analysis of similar reclamation projects, professional discussions, and Delphi survey. The eco-friendly indicators are theoretically based on the five elements of eco-friendliness; 1) resource consumption, 2) energy consumption, 3) pollution emission, 4) bio-diversity, 5) social amenity. The 69 indicators were explained in detail for the convenient use of the indicators by the potential users. The 69 indicators were classified into three categories such as pre-evaluation, process evaluation, and post-evaluation. In terms of spatial consideration, the 69 indicators were classified into two categories such as direct influence area and indirect influence area. Also the 69 indicators were classified into 7 categories: 1) sea, 2) lake, 3) agricultural land use, 4) industrial land use, 5) residential land use, 6) tourism land use, and 7) environmental land use. Twenty core indicators were selected from the 69 indicators by surveying the importance of each indicator. The core indicators are recommended in case of time and budget strain. When there are few quantitative data accumulated for the reclamation project, 5 macro indicators are recommended to be used. Macro indicators are qualitative in nature, and may be used in order to evaluate the overall eco-friendliness of a reclamation project.

  • School Crime Prevention Throgh Environmental Design (CPTED) is in the process of building a design guide through a lot of research. However, it is common practice to conduct consulting through existing cases and utilize internal self-evaluation through similar projects, as the self-evaluation criteria are not open to public or unlike other certifications. Therefore, the purpose of this study is to contribute to the development of a more quantitative and objective practical manual by analyzing the evaluation elements of school crime prevention environment design provided by guidelines and guidelines of various organizations and local autonomous bodies involved in school design. As a result of quantifying the school facilities CPTED indicators so far and incorporating the current guidelines, 'Surveillance and access control' of 'Entrance space and parking space' is found to be main. If the various indicators presented above are applied in consideration of the specificity of the school facilities in the application of the school CPTED technique, in addition to the CPTED for physically preventing offenses committed by outsiders, it can be expected to prevent violence among students or social crimes in school education.

  • Generally, mass concrete structural behavior is governed by the strain components. However, relevant guidelines in dam engineering evaluate the structural behavior of concrete dams using stress-based criteria. In the present study, strain-based criteria are proposed for the first time in a professional manner and their applicability in seismic failure evaluation of an arch dam are investigated. Numerical model of the dam is provided using NSAD-DRI finite element code and the foundation is modeled to be massed using infinite elements at its far-end boundaries. The coupled dam-reservoir-foundation system is solved in Lagrangian-Eulerian domain using Newmark-${\beta}$ time integration method. Seismic performance of the dam is investigated using parameters such as the demand-capacity ratio, the cumulative inelastic duration and the extension of the overstressed/overstrained areas. Real crack profile of the dam based on the damage mechanics approach is compared with those obtained from stress-based and strain-based approaches. It is found that using stress-based criteria leads to conservative results for arch action while seismic safety evaluation using the proposed strain-based criteria leads to conservative cantilever action.

  • The purpose of this study was to survey the use of a evaluation tools of clinical competency for nursing students. The sample consisted of the departments of nursing in 14 universities and 20 Junior colleges of nursing. Data analysis was done by frequency, percentages and factor analysis. The results of the study were as follows : 1. A common measurement tools for evaluation in the clinical area was used by 74.4% of universities and Junior colleges of nursing. Only 0-4.5% of Junior colleges of nursing and 1.5-7.4% of universities used a evaluation tools developed according to their major. 2. Theoretically, 3% of those sampled applied the nursing process as an instrumental means of nursing practice. Bloom's theory was applied by 35.8% of the schools. Most of them used their own measurement tools for evaluating their students. 3. One half of them used quantitative scales, the other half used others. 4. Professional attitudes wire included in their contents bvy 93.9% of universties and 94.1% of Junior colleges of nursing. The major areas of evaluation were knowledge, skills, attitudes and interpersonal relationships in that order. Results ; From this study can be concluded that regardless of the number of academic years of nursing and professional area, common standard evaluation tools for nursing competency were found to be needed. Theoretically, an evaluation scheme which applies the nursing process should be required. Knowledge, skill, attitude and interpersonal relationship would be essential elements to be evaluated. Maximizing the clinical competency and minimizing the conflict elements for nursing students is important. Nursing, education, students and environmental aspects must be consider in the goal of clinical education. A diagram, a checklist and a anecdote note in addition to the quantitative scale are necessary for efficient evaluation.

  • Most of the evaluations of environmental effect of construction of road do not run parallel with the evaluation of the propriety of the business, but it just reviews how to reduce contamination before the beginning of the construction work. This reveals the limitation of the induction of environment friendly development from the fundamental. In this study, a function of GIS spatial analysis for 9 elements of pre-evaluation of environmental effect has been introduced, and a GIS decision making system for environmental effect of a road has been established for an integrated evaluation by using individual evaluation result. By using GIS decision making system for pre-evaluation of environmental effect that has been developed in this study and the GIS data that has been collected, it would be possible to decrease time and money for evaluation as well as fulfill the requirement of objectivity. Therefore, it would be possible to apply for pre-evaluation of environmental effect when deciding on the route of the road at the beginning stage of the construction work. Also, through the system developed in this study, the construction body could easily induce a mutual agreement with the residents by the visual evaluation material, which might result in an evaluation of environmental effect while decreasing time and money at the beginning stage of the construction.

  • Recent developments in contactless, air-coupled sensing of seismic and ultrasonic waves in concrete structures are presented. Contactless sensing allows for rapid, efficient and consistent data collection over a large volume of material. Two inspection applications are discussed: air-coupled impact-echo scanning of concrete structures using seismically generated waves, and air-coupled imaging of internal damages in concrete using ultrasonic tomography. The first application aims to locate and characterize shallow delamination defects within concrete bridge decks. Impact-echo method is applied to scan defected concrete slabs using air coupled sensors. Next, efforts to apply air-coupled ultrasonic tomography to concrete damage imaging are discussed. Preliminary results are presented for air-coupled ultrasonic tomography applied to solid elements to locate internal defects. The results demonstrate that, with continued development, air-coupled ultrasonic tomography may provide improved evaluation of unseen material defects within structures.

  • With increasing population densities in cities, underground facilities and entertainment locations are proliferating at a rapid pace in efforts to maximize the use of land. The purpose of this study is to evaluate CO concentration level of subway stations having underground platforms in Busan Metropolitan City, from September to November 2000, over seven times. The places of inquiry include Yonsan-dong station, Somyon station, Busan station, Nampo-dong station and Dusil station. The samplings were conducted at three points of each station, i.e. gates, ticket gates, and platforms. The component of CO concentration is the main elements of indoor air quality evaluation. The total concentrations and average concentrations of CO were the higher at the Somyon station. The distribution of CO concentrations at each station, generally was higher at gate than ticket gates and platforms. The I/O ratios(I-platforms, 0-gates) were expressed highly than 1 at the Yonsan-dong station, Busan station, Nampo-dong station and were lower than 1 at the others.

  • There have been endeavors for sustainable development all over the world after the Rio World Summit and the idea of sustainable development has become common paradigm. Now, Korea has come to a situation where we need to apply the concept of sustainable development inevitably. Especially housing estate development must be preliminary change for sustainable development. Therefore, the objectives of this study were to establish sustainable planning element system of housing estate, and to propose a sustainable planning model compatible with the Korean situation. The scope of this study focused on typical multi-family housing estates in Korea and the environmental sustainable planning model. The model was developed from the evaluation of the important level and extra costs of planning elements for sustainable development of housing estate. The important level of planning principles and elements was analyzed by conducting a survey to experts. As the results of this study, four planning section ('land use and transport', 'pollution and waste', 'energy', and 'natural resource') and twelve planning items were identified. Twenty-one planning principles and fifty-five planning elements were found. Synthetically, the sustainable planning element system is composed of four planning sections, twelve planning items, twenty-one planning principles, and fifty-five planning elements. Based on survey to experts, $\ulcorner$The short-term strategic model$\lrcorner$ was developed for the social implosion of sustainable development, which is composed of ten basic elements, eighteen necessary elements, twelve optional elements, and seven arbitrary elements. $\ulcorner$The long-term future model$\lrcorner$was developed for application to from 10 to 15 years later. It is composed of fifteen basic elements, thirty-three necessary elements, and seven optional elements. The planning model proposed by this study can be used as a prototype for the development of a sustainable housing estate and can provide a practical tool for developers and planners who are not familiar with the concept of sustainable development.
