This study considered network quotient (NQ) of deluxe hotel employees and schematized characteristic attributes of being selected by employees with image through correspondence analysis in terms of cognition degree. Self-administrated questionnaires were completed by employees (292 samples) and data were analysed by frequency, t-test, one-way ANOVA, reliability and correspondence analysis. First, the hotel employees indicated the high average value in "participating in special education or seminar for improving ability ($3.85{\pm}0.76$). Second, as a result of analyzing difference according to gender, the average value in men was higher than in women. It was indicated that the higher age and career lead to a rise even in the average value of relationship index. Third, in consequence of carrying out correspondence analysis in order to prepare image map according to cognition level on relationship index in hotel employees, the measurement item that is placed in the closest distance to the response as saying of not so very was the response as saying of "having a lunch (dinner) engagement twice or three times a week." On the other hand, the response as saying of "tending to have many acquaintances compared to coworkers" was schematized in the close distance to the response as saying of very so.

대형복합재난은 자연재난과 사회재난이 연쇄적 또는 동시다발적으로 발생함에 따라 예측 가능한 범위 밖의 거대한 규모로 전개되는 재난을 의미한다. 대형복합재난은 재난의 동시성과 연쇄성으로 전혀 새로운 형태로 변화되어 기존의 재난관리방식과 다른 새로운 관리방식이 필요하게 된다. 이에 본 연구는 대형복합재난을 대상으로 선진외국의 복합재난대응체계를 검토하여 국내 복합재난 대응체계에 필요한 정책적 개선방향을 제시하였다.

Several water tanks installed in the building were damaged during the Gyeongju earthquake (2016) and the Pohang earthquake (2017). Since a water tank for fire protection is very important component, seismic safety should be ensured. In this study, an interaction between a water tank and a building was studied by the dynamic analysis of the RC building with the water tank. In case the water tank was installed on the roof of the RC building, it was confirmed that it did not significantly affect the response of the building. Based on the result, dynamic response characteristics of the water tank in the building were studied using two SDOF models represented dynamic behavior of the water tanks under earthquake. An earthquake time-history analysis was carried out with variables of aspect ratio of the tank, story of the building, and installed location in the building using three kinds of earthquakes.

Because of the burgeoning demand of the energy, the countries are finding sustainable solutions for these emerging challenges. Demand Side Management is playing a significant role in managing the demand with an aim to support the electrical grid during the peak hours. However, advancement in controls and communication technologies, the aggregators are appearing as a third party entity in implementing demand response program. In this paper, a detailed mathematical framework is discussed in which the aggregator acts as an energy service provider between the utility and the consumers, and facilitate the consumers to actively participate in demand side management by introducing the new concept of demand reduction bidding (DRB) under constrained direct load control. Paper also presented an algorithm for the proposed framework and demonstrated the efficacy of the algorithm by considering few case studies and concluded with simulation results and discussions.

1. Today mass communication informs us of the unethical behaviors of business almost everyday and the social interest about them including individuals implicated in loss and gain grows larger. It is the real aspect that business manager and scholars do not cope with the situation. 2. Five business ethical scales as justice theory, relativism, egoism, utilitarianism, deontological theory and information ethics were applied to this thesis. 3. Hypothesis : There will he a difference in the response on five ethical scales and the recognition degree of information ethics with consumers. 4. The response on five ethical scales with the sex of consumers showed a significant difference but that with the age showed a little difference that with the academic career showed a significant difference in justice theory, relativism, utilitarianism and deontological theory 5. The recognition degree of information ethics with the age and academic career of consumers showed a significant difference and the hypothesis was accepted, but that with the sex showed a little difference.

Mean squared error (MSE) is an effective criterion to combine the mean and the standard deviation responses in dual response surface optimization. The bias and variance components of MSE need to be weighted properly in the given problem situation. This paper proposes a systematic method to determine the relative weights of bias and variance in accordance with a decision maker's prior and posterior preference structure.

Korea, which entered the aged society in 2018, is accelerating the progress of the aged society due to the rapid decrease in birth. Although the low birth rate is the important issue, comprehensive measures to cope with the aged society should be established. In particular, the reform of the healthcare system in response to the aged society is very urgent. The reorganization of the healthcare system in response to the aged society should focus on improving the functional abilities of the elderly and should be transformed into integrated older person-centered health service. The benefit package of National Health Insurance should be diversified and appropriate payment of each benefit package should be applied. The ageism should be overcame, and it is important to recognize that the measures for the older person are investments in future society. The reform of healthcare system for older person are very urgent in Korea, which is advancing into a rapidly aged society.

인터넷 사용 증가로 인한 통신망에 대한 위협은 갈수록 증대되고 있다. 이에 대한 방안으로 많은 보안장비들이 개발되어 설치되고 있으며, 침입차단시스템에 이어 근래에는 침입탐지시스템에 대한 연구와 개발이 활성화되고 있다. 그러나, 네트워크의 규모가 커지고, 관리 대상 시스템의 수가 방대해짐에 따라 현재의 단일 네트워크 단위의 관리로는 해결이 어렵다. 본 논문에서는 IETF에서 진행되고 있는 PBNM(Policy-Based Network Management) 기술을 도입하여 대규모의 네트워크의 보안을 관리하기 위한 통합 침입탐지시스템(Integrated Intrusion Detection System:IIDS)을 설계한다. 통합 침입탐지시스템은 다수의 침입탐지 에이전트로 구성되어 있으며, 시스템의 요구사항과 기능별 요소들에 대하여 기술하고 있다.

This study was intended to identify customer's response to CRM of fashion business.488 questionnaires were distributed to male and female respondents aged 16 to 55, and then analyzed by descriptive statistics, oneway-ANOVA, chi-square test, and factor analysis. As a result of customer information management, respondents evaluated taste, interest and demographic informations as most valuable. But they did not value personal and credit information. For CRM concept, 4 factors were determined: continuous care and suggestion, particular service to important customer, customer management program development, and customer convenience consideration. For CRM activity, 3 factors were determined: customization, information offering, and programmed service strategies. Respondents were having positive attitude toward CRM concept and activity of fashion business. Among customer loyalty programs, they affected by immediate and direct programs most. The preference of customer contact methods was differentiated by sex and age groups. Males and teenagers preferred e-mail, and females preferred catalog and telephone connection.

One of the most difficult tasks in pavement management information systems is establishing the links between performance measures of a structure and the design and construction inputs. In-situ pavement performance can be considered a response variable to many project input variables, such as design, construction, and traffic loading effects. If we are to fully understand the component of pavement performance and specify the inputs through design and construction specifications to achieve that performance we must develop quantitative relationship between input and response variables through a scientific, fully integrated Pavement Performance Analysis System (PPAS). Hence, the objective of this study is to design a database model required for developing an effective database template that will allow analysis of pavement performance measures based on design and construction information linked by location. In order to select the most appropriate database model, a conceptual database model (Entity Relationship Model) and dimensional model, which is believed to be the most effective modeling technique for data warehouse project, are designed and compared. It is believed that other state highway agencies could adopt the proposed design strategy for implementing a PPAS at the discretion of the state highway agencies.
