본 논문에서는 표준망 관리 프로토콜인 CMIS/CMIP에서 M-Cancel-Get 서비스를 이용한 트래픽 제어방안을 제시하고 성능분석을 하였다. 복수응답 기능단위를 허용하는 M-Get 서비스는 피 관리시스템의 속성을 검색하는 서비스로서 관리 특성상 일상적이고 대량의 응답을 요구하는 서비스이다. 이때 관리응답은피관리시스템이 네트워크의 상황이나 관리시스템의 상황과 무관하게 전송하게 된다. 이에 대해 관리시스템은 자신이 발생시킨 M-Get 서비스의 취소를 알리는 M-Cancel-Get 서비스를 요청할 수 있다.M-Cancel-Get 서비스를 트래픽 제어를 위해 사용하는 경우, 복수응답 패킷수를 증가시키면서 관리응답 시간에 대해 시뮬레이션을 하여 적정 트래픽 제어 시점을 제안하였다. 그리고 그 결과를 백뷴율로 적용하면서 네트워크 부하에 따른 처리율과 일반 패킷의 평균 지연시간에 대해 분석하였다. 그 결과 본 논문에서 제시한 트래픽 제어변수가 처리율과 평균 지연시간에 있어서 우수함을 알 수 있으며, 특히 일반 트래픽이 차지하는 기본 트래픽 밀도가 증가할수록 성능이 향상 됨을 알 수 있다.

The purpose of this study is to examine the cognitive responses and the corresponding behavior responses of consumers who have experiences in not being able to buy a product in an online shopping mall due to it being sold-out. Responses were gathered from 526 consumers between the ages of 20 to 40 years residing in a metropolitan area. Each person surveyed had experienced a situation in which a product that they wanted to purchase from an online shopping mall was sold-out. SPSS 18.0 was used to perform frequency analysis, factor analysis, reliability analysis, and regression analysis. The first set of results of this study showed positive responses of quality, discernment, scarcity, but also negative cognitive responses of careless management, manipulation of shopping mall management, and common taste. In negative cognitive responses, sold-out situations caused consumers inconvenience. The second set of results revealed that quality, discernment, and careless management had a significant effect on product replacement (Substitute, S); likewise, factors such as quality, discernment, careless management, manipulation by shopping mall designers, and common taste had a significant effect on the delay of purchasing decisions (Delay, D). Scarcity, careless management, manipulation by shopping mall designers, and common taste also demonstrated significant influence on the incomplete leaving of stores (Incomplete Leave, L1), while discernment, scarcity, careless management, manipulation by shopping mall designers, and common taste had a significant influence on the complete leaving of stores (Complete Leave, L2). Previous studies have examined the behavioral response topics of substitute, delay, and leave. These study results suggest that product sellouts at online shopping malls did not have a solely negative effect on consumers. It actually had a positive effect in terms of discernment, scarcity, and the perception of quality of sold-out products. Furthermore, both positive and negative cognitive responses had various effects on behavioral responses.

반복되는 재난을 효과적으로 대응하기 위해서는 과거에 수행한 재난 대응 업무로부터 생산된 기록들의 체계적인 관리가 무엇보다도 중요하다. 흩어져 있는 재난안전 기록정보자원을 기록관리체계로 편입하기 위해서는 먼저 기능분류체계(BRM) 개발이 필요한데, 본 연구에서는 이를 위한 선행 연구로 위기관리 표준매뉴얼(SOP)을 대상으로 재난안전 공통업무를 분석하였다. 총 28개의 매뉴얼을 대상으로 3차에 걸친 분석을 실시하였으며, 그 결과 1,667개의 주요업무가 추출되었고 이는 다시 5개의 중분류 유형, 20개의 소분류 유형으로 그룹핑되었다. 나아가 업무유형별 생산 예상 기록을 살펴봄으로써 재난안전 업무의 수행 및 재난안전 기록정보자원 관리 측면에서 시사점을 도출하였다.

Ministry of Environment developed ‘Emergency Response Information System (ERIS)’ in 2001, which is in operation. As a next step, currently National Emergency Response Information System (NERIS) is being developed. The main difference among ERIS and NERIS is to enhance the system in the national level, including transportation of hazardous materials. This paper introduces concepts and methods applied to NERIS, especially HAZMAT, and the information system, operating strategies. Based on GIS and transportation-network data, the best route can be offered using Risk Analysis. Strategies for reporting and first-response information systems are also designed for emergencies in the paper.

For the count response we normally consider Poisson regression model. However, the conventional fitting algorithm for Poisson regression model is not reliable at all when the response variable is measured with sizable contamination. In this study, we propose an alternative fitting algorithm that is resistant to outlying values in response and report a case study in semiconductor industry.

Taguchi's parameter design seeks proper choice of levels of controllable factors (Parameters in Taguchi's terminology) that makes the qualify characteristic of a product optimal while making its variability small. This aim can be achieved by response surface techniques that allow flexibility in modeling and analysis. In this article, a collection of response surface modeling and analysis techniques is proposed to deal with the multiresponse optimization problem in experimentation with Taguchi's signal and noise factors.

The digital response is an excellent infection prevention and control measure to minimize person-to-person contact when a respiratory infectious disease is rapidly spreading. However, few studies have explored the reasons for the development and utilization of these technologies. Here, we analyze documents by the Korean government, existing research, and news articles to provide a qualitative review of the digital response, and new concepts explored by Korea during coronavirus disease 2019, to apply them for the next infectious disease outbreak.

The purpose of the establishment of corporation's Business Continuity Plan(BCP) is to maintain corporations' own business and establish the response plan in order to resume operation in a short time period when crisis situations occur due to natural disaster and human error. This study has presented all types of procedures and criteria which are needed to establish the airport crisis response system in order to maintain the business continuity by utilizing BCP technique. Basically the risk response procedures must be established in the process of (1) preparation stage, (2) plan development stage, (3) documentation stage, (4) test & maintenance stage. The guideline has been suggested that each stage must be carried out in the sequence of Policy & Planning Responsibility, Business Impact Analysis, Recovery Strategy & Plans, Emergency Plan & SOP, Training Awareness and Maintenance & Review

We study on the dynamic interaction with a simulated physical-biological coupled model response to nutrient reduction scenario in Jinhae Bay. According to the low relative errors, high regression coefficients of COD and DIN, and realistic distribution in comparison to the observation, our coupled model could be applicable for assessing the marine ecosystem response to nutrient input reduction in Jinhae Bay. Due to the new construction and expansion of sewage treatment plant from our government, we reduce 50% nutrient inputs near Masan Bay and sewage treatment plant. COD achieves Level II in Korea standard of the water quality from the middle of the Masan Bay to all around Jinhae Bay except the inner Masan Bay remaining at Level III. When our experiment reduces 50% nutrient inputs near Masan Bay and Dukdong sewage treatment plant simultaneously, COD decreases to about 0.1-1.2 mg/L $(128^{\circ}30'{\sim}128^{\circ}40'\;E,\;35^{\circ}05'{\sim}35^{\circ}11'\;N)$. The COD from the middle of the Masan Bay to Jinhae Bay achieves Level II.

In order to manage a cluster system that consists of a number servers, management aspects such as configuration management, fault management, performance management, and user management should be considered. Especially, it is necessary to monitor performances for performance and fault management. An agent in each server collects performance counters, status changes, and events occurred in normal or abnormal states. The data collected are delivered to a collector sorter and processed in a report tool for performance analysts and management decision in the cluster system point of view, by detecting fault state and tracing out resource usage, service response, and response, and states until failed. In this paper we propose an architecture modeling of a performance report tool for proactive cluster system management. Some results on a cluster system are presented.
