This study aims to create a disaster management system after an earthquake. Japan's earthquake disaster management system, including the Disaster Countermeasures Basic Act, addresses all of the disaster phases of prevention, mitigation, preparedness and emergency response as well as recovery and reconstruction with roles and responsibilities among the national and local governments clearly defined. Korea's earthquake disaster management system are including the Disaster Countermeasures Basic, but when the 9.12 earthquake occurred, problems such as insufficient early response, study on the earthquake lack were revealed. This study conducted a field survey and analyzed coping process after Po Hang earthquake. Therefore, this study have found that Disaster Management Headquarters are operated rapidly. They are coped with urgent safety inspection for damage facilities and soil liquefaction with advanced equipment. And The headquarters interviewed with victims. So they found out What the victims needed. However, when carrying out relief activities, Research of temporary housing and allocation of donations was not rapid. Further, this study have found that earthquake specialists were lack and disaster information transfer was not working. This study will be utilized as fundamental data in planning disaster management system after an earthquake.

Recent concerns about environmental conditions have triggered the growing interest in using green energy resources. These sources of energy, however, bring new challenges mainly due to their uncertainty and intermittency. In order to alleviate the concerns on the penetration of intermittent energy resources, this paper investigates impacts of realizing demand-side potentials. Among different demand-side management programs, this paper considers demand response wherein consumers change their consumption pattern in response to changing prices. The research studies demand response potentials from different load sectors on generation system well-being. Consumers' sensitivity to time-varying prices is captured via self and cross elasticity coefficients. In the calculation of well-being indices, sequential Monte Carlo simulation approach is accompanied with fuzzy logic. Finally, IEEE-RTS is used as the test bed to conduct several simulations and the associated results are thoroughly discussed.

In most developed countries, Extreme heat alter system operates every summer and the response plan to be issued according to this system is composed of some government agencies sub-plans. The National Emergency Management Agency in Korea develops response plan but it is not composed of the definition of the heat vulnerability and the concrete agency roles. Therefore, this study analyses foreign cases in three processing: preparedness, response, recovery and reviews the status of heat response plan. As a conclusion, the study suggests two ways of Extreme heat management into Korean heat response plan such as strengthening its institutional position and complementing its context.

Physical and psychological events can produce stress response in various degrees. Stress affects many aspects of physiology including both brain and peripheral elements which is represented as hypothalamus-pituitary-adrenal axis. Brain elements consist of corticotropin-releasing hormone(CRH), locus ceruleus(LC)-norepinephrine(NE)/autonomic system. Peripheral elements include pituitary-adrenal axis and the autonomic nervous system, which coordinate the stress response. Current trend of the stress researches is emphasizing the mechanisms of the stress response which is adaptive or become maladaptive. This review introduces 1) the concepts of stress, 2) physiological and behavioral aspects of stress responses, 3) the consequences of stress response, 4) the measurements of stress and 5) stress management for those interested in stress research.

Chemicals are an indispensable element of modern society to the extent that more than 15 million species are commercially available worldwide. However, among them are chemicals whose toxicityposes a threat to public health and the environment, as illustrated by past cases of chemical accidents, which revealed their danger to human life. Chemical accidents can spread and cause huge damage in a short time because of their characteristics. Therefore, it is important to do as much as possible to prevent them in advance and to respond promptly after an accident. The legal system pertaining to domestic chemical substances is the "Toxic Chemical Control Act", which is made up of the "Act on the Registration and Evaluation of Chemicals" and the "Chemical Control Act" since 2015. Under this law, the Comprehensive Chemical Information System and Chemical Substance Data Processing system were established and are still operating;however, chemical accidents are still occurring. These systems are comprehensive information systems aimed at providing chemical information rather than acting as chemical response systems, which has limited the effectiveness of accident response. This study is intended to analyze the information management systems, response management systems and the basis of chemical substance management support for hazardous chemicals and suggest ways to improve the legal system for developing and operating chemical response systemswithin a municipality.

With the increasing proliferation of World Wide Web, electronic mail systems have become very widely used communication tools. Researches on e-mail classification have been very important in that e-mail classification system is a major engine for e-mail response management systems which mine unstructured e-mail messages and automatically categorize them. in this research we develop e-mail classifiers for e-mail Response Management Systems (ERMS) using naive bayesian learning and centroid-based classification. We analyze which method performs better under which conditions, comparing classification accuracies which may depend on the structure, the size of training data set and number of classes, using the different data set of an on-line shopping mall and a credit card company. The developed e-mail classifiers have been successfully implemented in practice. The experimental results show that naive bayesian learning performs better, while centroid-based classification is more robust in terms of classification accuracy.

Climate change, rapid urbanization, and population concentration have led to a higher frequency and magnitude of disasters in the world. Recently, the occurrence of large-scale complex disasters, which are caused by a combination of natural disasters, man-made disasters, and social disasters, is increasing. In Korea, there are many case studies of damage prediction and response technology development for individual natural disasters, such as earthquakes, floods, and typhoons. On the other hand, the system basis for the efficient response and management of large-scale complex disasters is insufficient. Therefore, this study examined the representative cases of natural, social disasters, and related cases of domestic disaster response management systems. In addition, this paper proposes ways to improve the legal system for complex disaster management policies and establish a cooperation system between the ministries for an efficient response.

In this paper, we present POSSDM (POSTECH Situation-Based Dialogue Manager) for a spoken dialogue system using a new example and situation-based dialogue management technique for effective generation of appropriate system responses. Spoken dialogue system should generate cooperative responses to smoothly control dialogue flow with the users. We introduce a new dialogue management technique incorporating dialogue examples and situation-based rules for EPG (Electronic Program Guide) domain. For the system response inference, we automatically construct and index a dialogue example database from dialogue corpus, and the best dialogue example is retrieved for a proper system response with the query from a dialogue situation including a current user utterance, dialogue act, and discourse history. When dialogue corpus is not enough to cover the domain, we also apply manually constructed situation-based rules mainly for meta-level dialogue management.

In this paper, I present a new echo canceller using the adaptive cascade system identification (CSI) method, which a system response is divided into several responses so that each response is adaptively estimated and combined. Echo cancellation is required for a dual-duplex DSL, in order to allow each individual loop to operate in a full duplex fashion. Echo cancellation was one of the most difficult aspects of DSL design, requiring high linearity and total echo return loss in excess of 70 dB. Especially, for a fickle response, if the response is estimated by an adaptive filter, the filter needs more taps and the performance is decreased. But the response is divided into several responses, the computation complexities are decreased and the performance is increased. For the stage constant n, which represents the number of stages, if the response is not divided (n=1), the computation complexity of multiply is $2N^2$. And if the response is divided into two responses (n=2), the computation complexity of multiply is $2N^2$. Also, if n=3, the computation complexity is ${\frac{2}{3}}N^2$. Therefore, it is known that the computation complexity is decreased as n is increased. Finally, this proposed method is verified through simulation of echo canceller for digital subscriber line (DSL) application.

The purpose of this study is to find out how any organizational response or dispute-related consulting has a significant impact on management performance before or during a dispute over a construction subcontract dispute. In this study, multiple regression models were used to analyze the impact on consulting performance. According to the result of the analysis, the positive effects on the overall external consulting effect is influenced by five variables such as financial values, increase of the number of disputes, construction of response system by contents, construction of response system in each period, dispute response external response system. The original business operators were also more likely to be affected by internal activities of conflict response companies and the extent to which external response systems were established. This means that the supply and demand service provider's business environment is relatively poor, forcing it to be lower than the internal and external activities and influences of the original business operators of the conglomerates.
