Since the Denial of Service Attack against multiple targets in the Korean network in private and public sectors in 2009, Korea has spent a great amount of its budget to build strong Internet infrastructure against DDoS attacks. As a result of the investments, many major governments and corporations installed dedicated DDoS defense systems. However, even organizations equipped with the product based defense system often showed incompetency in dealing with DDoS attacks with little variations from known attack types. In contrast, by following a capacity centric DDoS detection method, defense personnel can identify various types of DDoS attacks and abnormality of the system through checking availability of service resources, regardless of the types of specific attack techniques. Thus, the defense personnel can easily derive proper response methods according to the attacks. Deviating from the existing DDoS defense framework, this research study introduces a capacity centric DDoS detection methodology and provides methods to mitigate DDoS attacks by applying the methodology.

There have been many requests for development of senior housing in Korea. Therefore it was very important to review how senior houses are established and managed in other countries. In this point, this research compared the actual conditions of the homes for the elderly in the U.K, U.S.A and Japan. Through the process, this research aimed to find the implications for Korea. The research was conducted by the literature review on senior congregate housing with Franklin's(1998) social constructionism perspective. This kind of research might be utilized as a theoretical framework for performance of any systems of housing for the aged. In this study, the researchers suggested the implications of senior congregate housing as follows. Firstly, in terms of structural context, government in the U.K, U.S.A., and Japan were positively concerned with solving the housing problems for senior citizens despite some differences. Secondly, from an institutional context, institutions related with provision, construction, and management of senior congregate housing were systematically consolidated and they all adapted the housing and welfare policy. Thirdly, in organizational context, there was an organization in charge of provision and management that exclusively oversaw the housing for the elderly in both the public and private sectors. Fourthly, in operational context, standards regarding space were clearly set both for individual units and common spaces as well as for facilities and services for the residents. Finally in terms of intersubjective context, the competency of housing manager and ways to involve the families which were important for residents' independent life were under study.

The construction supervisors of the public companies are usually responsible for process management, quality management, safety management, and many other various tasks that occur during construction project. Public companies such as Korea Highway Corporation have developed a framework and manual for management and supervision of construction projects. But, there has been the change of business environment such as increase of private investment project and the introduce of construction management system recently. It has been necessary for construction supervisor to streamline the current project management system in the owner's aspect in order to cope with the expected new challenges. Accordingly, this research has been investigated and analyzed the operation system between Korean supervisor and foreign supervisor in their public corporation. This research has suggested the advanced project management in their public corporation. Especially, this study has proposed the construction management manual for supervisors such as inspectors training, supervisors construction manual, and supervisors training road map.

Promotion of immunization including early recognition of disease symptoms and effective control of communicable disease have been the important role of the school heath teacher in Korea. The school heath teacher as a nurse have been practiced vaccination for students as one of the major method for promotion of immunization in school. Recently it was occured difficulty for school vaccination that is practicing by school health teacher. So it is predicted for reducing of vaccination coverage rates of students. The objectives of this study are, first; to examine current guidlines of government, second, to analysis problem according to current guidline, third, to discuss further direction for school vaccination. There are used study methods as litrature review, analysis of statistical data and case study etc. Analytical framework for increased effects of vaccination in this study was safty, cost -effectiveness and coverage rates of vaccination. Major suggestions are as follows : First, It is different from the role of the public and private sectors in preventive health services. The preventive health services are characterized that the effect of health promotion is large, but the period of input effect is slow. Therefore the leading role of school vaccination should be have school and school health teacher including public sectors. Second, Health management of contemporary people can be effective with cooperative relationship between various health manpower. School health teacher as a medical manpower should be provide vaccination service continiously for health promotion of students. Third, It is necessary to maintain collective vaccination in school because have lots of advantage at safty, cost-effectiveness and coverage rates. In conclusion, school heath teacher should have central and independent role in school vaccination in according to current law. Also it will be assured lawful compensation in prepare to accident in vaccination.

According to Plato's ontology, we lead our lives by establishing a relationship with others in the society. However in rapidly changing era, our lives was gradually moving towards personal tendency. Even for the relationship with family, not with others. Thus, awareness about owning properties has changed due to the sociocultural factors and increase number of single-person households. So in this study, the considerations for single-person housing were perceived through preceding research, and the elements making spatial boundary of shared housing were drawn to make rational space sharing based on the boundary with others and of the living environment. With overall analysis based on the spatial boundary features of planned shared housing, the plan characteristics according to the spatial boundary of the current shared housing is to be drawn and analyzed. Third, The expressive and structural features of spatial boundary as above appear with mutual flexible connectivity, And the result shows that the modularity was the highest. Among them variable coupling modularity of shows how it is possible to combine efficiently and variously the private and public spaces with regularity of 'space of optimal unit'. This study drew plan characteristics from more detailed space border of shared housing. Therefore, The basic framework of the characteristics spin for the cases that newly emerge later on.

In line with the trend of global transport volume which has increased rapidly over the years, internal transportation in seaports is always conducted with high frequency. Thus, there is always much potential for traffic jams as well as high transportation costs and emissions. Many efforts have been initiated to streamline the inter-terminal container transport (ITT) through the development of automated vehicles and equipment as well as using private transport facilities to overcome these limitations. The purpose of this paper to develop a framework to design, analyze, and validate the efficiency of a new ITT system in a port area based on the monorail network and automatic vehicles. First, the number of shuttles and loaders was determined depending on the transport demand scenario. Next, a simulation model was applied to evaluate the system performance as well as gain more insight into the working process of the ITT system. Finally, by setting goals for the performance indicators, the results showed that the system was highly efficient with 100% of the containers delivered to their destination on time. Besides, a series of other performance tracking was provided to provide insight into the system's capabilities.

Purpose: At the time of consensus on the necessity of appropriate guidelines for health care facilities suitable for Korea, the paper aimed to analyze the characteristics in the aspect of the system of the US Health Care Facility Guidelines(FGI Guidelines) and to suggest implications. Since the system is significant for the guidelines to be socially accepted and operated, this study focuses on the system. Methods: Literature studies focusing on the analysis of prior studies and the 2018 edition of the FGI Guidelines were conducted. Results: As a result of reviewing the history and outline of the FGI Guidelines, the derived characteristics of the system were governance, procedure, and composition. First, it had multi-layered organization and multidisciplinary members. Secondly, the focus is on the procedure of gathering opinions from industry and the public. Third, the Guidelines have been continuously evolving to reflect the needs of the times and changes in the medical environment, and the content framework and method of writing are user-friendly in order to prevent confusion caused by vast contents. Implications: First, we need to consider the composition of a private organization to prepare Korean health care facility guidelines. Second, it needs a system that can induce the participation of multidisciplinary experts. Third, a comprehensive and user friendly guideline needs to be constructed.

In the absence of a clear command and control structure, a key challenge in supply chain management is the coordination and alignment of the supply chain members who pursue divergent and often conflicting goals. The newsvendor model is typically used as a framework to quantify the cost of misalignment and to assess the impact of coordination initiatives. This paper considers a fuzzy approach for the newsvendor problem which includes a single manufacturer and a single retailer. We use several fuzzy parameters in the model such as the demand, the wholesale price, and the market sales price. We apply a coordination policy, referred to as buyback, to solve the fuzzy newsvendor problem. Based on the buyback policy, the optimal order quantity of the retailer can be computed, and the possible profits of the members in the supply chain can be calculated with minimum sharing of private information. Focusing on the fuzzy model with buyback policy for the newsvendor problem, we illustrate exemplary fuzzy models. We also illustrate an integration model, which extends a single-manufacturer-single-retailer model to the single-manufacturer-multiple-retailer setting. In the extended model, we consider three coordination policies including quantity discount, profit sharing, and buyback, as well as non-coordination case.

This paper illustrates some practical geographic information system (GIS) applications for aiding fishery managers and coastal area planners in analysing the likely control scheme of coastal farming areas, and in providing a flexible framework for decision making on fishery development and zoning issues. The effective management of marine farming operation is vitally important since it can greatly influence economic availability by determining capital outlay and by affecting running costs, rates of productions and mortality factors. GIS has been widely adopted elsewhere as a potent management tool in both the private and public sectors. GIS is now being extensively adopted in marine-associated activities. Here, we have used GeoMania v2.5 GIS software and its 3D Analyst extension module to visualize marine farming areas data that were collected around the Jinhae bay.

In comparison with the long and continuous his-tory of research in the general area of stress and coping, theoretical and clinical interest in family stress and adaptation is a recent phenomenon. To understand the phenomena of family behavior, a comprehensive theoretical framework is needed to us provide an adequate background to for research. This study was designed to develop and test a hypothetical model for family stress and adaptation in families with handicapped children. A hypothetical model was constructed on the basis of the family stress theory developed by McCubbin etc. The model included six paths. For the purpose of model testing, empirical data was collected from May to August, 1992. The subjects of the study were 190 parents of chidren in five special schools and one private institute in Seoul and Choong Nam. An SPSS P $C^{+}$ and PC-LISREL 7.13 computer programs were used for descriptive and covariance structure analysis. The results of the study are as follows. (1) Family Stress(${\gamma}$$_{3l}$=-.288, T=-4.942) had a direct effect on Family Adaptation. (2) Family Functioning ($\beta$$_{21}$=-.373, T=5.595) had a direct effect on Situational Definition. (3) Family Functioning ($\beta$$_{31}$ =.334, T=5.375) had a direct effect on Family Adaptation. (4) Situational Definition( a2=.270, T=4.285) had a direct effect on Family Adaptation The model was supported by the empirical data. Thus it is suggested that the model could be adequately applied to family nursing care of families with a mentally handicapped child. In particular, the nursing interventions that enhance family functioning and the situational definition would improve family adaptation in families with mentally handicapped children.n.n.
