The purpose of this study is to identify the relationship between pro-environmental consumption consciousness and resource saving behavior of university students. This research has been conducted in 2005 through a written questionnaire with the students of a university in Seoul. After a preliminary research, the main research bas been executed in number of 616 copies. The date were analyzed by statistical methods such as frequencies, precentiles, means, the standard deviations, Crobach's a coefficient, one-way ANOVA, and multiple regression analysis using SPSS statistics program. The major findings of this study were as follows. The pro-environmental consumption consciousness of the university students is the most important factor of doing resource saving behavior. The university students are the group that is going to take responsibility for a national economy and future society. Therefore, it is very important to educate them for establishing the rational consciousness of consumption in order to improve their consumption behavior and skills, because the consciousness formed in this period leads to the propensity to consume when they become adults.

Material failure behavior is generally dependent on loading rate. Especially in brittle and quasi-brittle materials, rate dependent material behavior can be significant. Empirical formulations are often used to predict the rate dependency, but such methods depend on extensive experimental works and are limited by practical constraints of physical testing. Numerical simulation can be an effective means for extracting knowledge about rate dependent behavior and for complementing the results obtained by testing. In this paper, the failure behavior of a brittle material under different loading rates is simulated by molecular dynamics analysis. A notched specimen is modeled by sub-million particles with a normalization scheme. Lennard-Jones potential is used to describe the interparticle force. Numerical simulations are performed with six different loading rates in a direct tensile test, where the loading velocity is normalized to the ratio of the pseudo-sonic speed. As a consequence, dynamic features are achieved from the numerical experiments. Remarkable failure characteristics, such as crack surface interaction/crack arrest, branching, and void nucleation, vary in case of the six loading cases. These characteristics are interpreted by the energy concept approach. This study provides insight into the change in dynamic failure mechanism under different loading rates.

In this paper, a new user identification method is presented using real environmental human-computer-interaction (HCI) behavior data to improve method usability. User behavior data in this paper are collected continuously without setting experimental scenes such as text length, action number, etc. To illustrate the characteristics of real environmental HCI data, probability density distribution and performance of keyboard and mouse data are analyzed through the random sampling method and Support Vector Machine(SVM) algorithm. Based on the analysis of HCI behavior data in a real environment, the Multiple Kernel Learning (MKL) method is first used for user HCI behavior identification due to the heterogeneity of keyboard and mouse data. All possible kernel methods are compared to determine the MKL algorithm's parameters to ensure the robustness of the algorithm. Data analysis results show that keyboard data have a narrower range of probability density distribution than mouse data. Keyboard data have better performance with a 1-min time window, while that of mouse data is achieved with a 10-min time window. Finally, experiments using the MKL algorithm with three global polynomial kernels and ten local Gaussian kernels achieve a user identification accuracy of 83.03% in a real environmental HCI dataset, which demonstrates that the proposed method achieves an encouraging performance.

ESG는 모든 기업에게 선택이 아닌 필수 사항이 되었으며, 국내 주요 은행들도 ESG 경영을 적극적으로 실천하고 있다. 은행은 ESG 내부활동 뿐만 아니라 자금공급의 중개자로 ESG 금융을 제공하는 역할을 수행하고 있다. 최근에는 디지털 신기술과 결합하여 친환경 활동 수행 시 우대금리를 제공하는 ESG 금융상품을 출시하고 있다. 그러나, 무분별한 우대금리 제공은 은행의 수익성에 악영향을 미칠 수 있으며, 환경인식 개선에 실질적으로 기여하지 못할 경우 그린워싱(Greenwashing) 문제에 직면할 수 있다. 이에 본 연구는 전기 절약과 연동된 ESG 디지털 적금상품을 연구 대상으로 선정하고, 가입자의 실제 데이터를 통하여 소비자의 환경인식과 저축행동을 실증적으로 분석하였다(표본수 2,478개). 본 연구의 주요 결과는 다음과 같다. 첫째, ESG 디지털 적금상품의 가입 현황을 분석한 결과, 30~50대가 주요 고객층으로 나타났으며, MZ세대는 다른 세대에 비해 전기 절약 실천을 통한 우대금리 달성에 있어 상대적으로 높은 성과를 보였다. 둘째, 소비자의 환경인식은 ESG 금융상품의 목표 달성에 유의한 영향을 미치는 것으로 나타났다. ESG 디지털 적금상품은 저축의 기본 기능에 충실함과 동시에 환경인식을 높이는 데 기여할 수 있음이 확인되었다. 셋째, 환경인식은 소비자의 저축 납입행동을 유도하지 못했으며, 이는 지속적인 소비자 관여가 필요함을 시사한다. 본 연구는 환경인식(Environmental Awareness)과 저축행동이론(Theory of Saving Behavior)을 기반으로 ESG 금융상품의 목표 달성에 미치는 소비자 인식 및 행동을 학문적으로 설명하였다. 연구의 결과는 ESG 금융상품의 우대금리 설계의 적정성이 중요함을 시사한다.

The purpose of this study is to examine the differences of use behavior and environmental perception of a park and to analyze the influence of environmental perception factors on park satisfaction among 7 parks in Suseong-gu, Daegu. The data from the 255 questionnaires of young adults (30-59) and old adults (more than 60) who use the park more than once a week were used for the analysis. In terms of park use behavior, young adults used the park for walking and jogging mainly on weekday evenings, while old adults used the park for walking and rest mainly during weekday daytimes. In addition, old adults used the park more times a week than young adults, and spent more time in the park. In the analysis of the environmental perception of the park, similar results were found in both age groups but overall, old adults were more satisfied with the park environment than the young adults. As a result of analyzing the influence of environmental perception factors, it was determined that park satisfaction in young adults has a significant influence on 'use amenity', 'use convenience', 'facility suitability', and 'landscape diversity' in this order. On the other hand, park satisfaction for old adults has an influence on 'use amenity', 'facility suitability', and 'use convenience' in this order. The findings of this study can be used as an effective basic data for future park planning considering age groups.

The Purpose of this study is to understand the relationship between residential environment and healthy behavior by examining the effect of environmental stress on psychology and physiology. With anxiety, the acute environmental stressor activates sympathy nerve system and the chonic environmental stressor activates the intenal secretion system because this stress induces depression. Thus, we could find that the continuity of these kinds of stresses brings the chronic disease.

The purpose of this study is to develop an environmental education program for environmentally friendly consumer behaviors by analyzing factors influencing the attitude-behavior relationship, and examining consumer information needs about environmental problems. Environmental information demanded by consumers could be classified into five main areas; 'use and disposal of environmentally friendly resources', 'purchase of environmentally friendly goods', 'environmental problems and consumer sovereignty', 'environmental laws and regulations' and 'environmental values and consumer's civil consciousness'. Based on the study results, an environmental education program for consumers was developed which consisted of two main parts, basis and practice. The former aimed to strengthen consumer consciousness about environmental problems and the latter, to make regular environmentally friendly consumer behaviors. The two parts were correlated. Thus strengthening environment-related consumer consciousness by learning the part of basis could promote of environmentally friendly consumer behaviors.

In this paper, we propose a method of cooperative control based on immune system in distributed autonomous robotic system(DARS). Immune system is living body's self-protection and self-maintenance system. Thus these features can be applied to decision making of optimal swarm behavior in dynamically changing environment. For the purpose of applying immune system to DARS, a robot is regarded as a B lymphocyte(B cell), each environmental condition as an antigen, and a behavior strategy as an antibody respectively. The executing process of proposed method is as follows. When the environmental condition changes, a robot selects an appropriate behavior strategy. And its behavior strategy is simulated and suppressed by other robot using communication. Finally much simulated strategy is adopted as a swarm behavior strategy. This control scheme is based on clonal selection and idiotopic network hypothesis. And it is used for decision making of optimal swarm strategy.

In this paper, we propose a method of cooperative control(T-cell modeling) and selection of group behavior strategy(B-cell modeling) based on immune system in distributed autonomous robotic system(DARS). Immune system is living body's self-protection and self-maintenance system. Thus these features can be applied to decision making of optimal swarm behavior in dynamically changing environment. For the purpose of applying immune system to DARS, a robot is regarded as a B cell, each environmental condition as an antigen, a behavior strategy as an antibody and control parameter as a T-call respectively. The executing process of proposed method is as follows. When the environmental condition changes, a robot selects an appropriate behavior strategy. And its behavior strategy is stimulated and suppressed by other robot using communication. Finally much stimulated strategy is adopted as a swarm behavior strategy. This control scheme is based of clonal selection and idiotopic network hypothesis. And it is used for decision making of optimal swarm strategy. By T-cell modeling, adaptation ability of robot is enhanced in dynamic environments.
