Recently, an attack to an application incapacitates the intrusion detection rule, the defense policy for a network and database and induces intrusion incidents. Thus, it is necessary to study integration security to ensure the security of an internal network and database from that attack. This article is about building an integration security system to prevent an attack to an application set with intrusion detection rules. It responds to network-based attack through detection, disperses attack with the internal integration security system through virtual clustering and load balancing, and sets up defense policy for attacking destination packets, analyzes and records attack packets, and updates rules through monitoring and analysis. Moreover, this study establishes defense policy according to attacking types to settle access traffic through virtual machine partition policy and suggests an integration security system applied to prevent attack and tests its defense. The result of this study is expected to provide practical data for integration security defense for hacking attack from outside.

Spatial distribution analysis of industrial locations plays a very important role in the establishment of relevant spatial policies and plans. The first thing to consider in this analysis is what analysis indicators and spatial units are used, because the interpretation of the analysis results may vary depending on the analysis indicators and the spatial units. Therefore, this study first examines various industrial integration indicators considering spatial autocorrelation and suggests the classification of regional types of industrial aggregation through the combination of related indicators. And then, this paper aims to empirically analyze the root industry by presenting a methodology for analyzing industrial integration by various spatial units such as individual locations, grids, and administrative districts. The results of the empirical analysis show that the grid in the spatial unit can be analyzed in more detail than the administrative unit. In addition, it is expected to overcome the limitations such as differences in interpretation that may occur due to the setting of spatial units. In the classification of regional types, the south-eastern region of Ulsan, Busan, and Changwon, and the western region of the SMA of Incheon, Hwaseong, and Ansan were analyzed as the industrial cluster type.

The non-linear static analysis of reinforced concrete (RC) structures using the three-dimensional (3D) finite element method is a time-consuming and challenging task. Moreover, this type of analysis encounters numerical problems such as the lack of convergence of results in the stages of growth and propagation of cracks in the structure. The time integration analysis along with the mass scaling (MS) technique is usually used to overcome these limitations. Despite the use of this method in the 3D finite element analysis of RC structures, a comprehensive study has not been conducted so far to assess the effects of the MS method on the accuracy of results. This study aims to evaluate the accuracy of the MS method in the non-linear quasi-static finite element analysis of RC structures. To this aim, different types of RC structures were simulated using the finite element approach based on the implicit time integration method and the mass scaling technique. The influences of effective parameters of the MS method (i.e., the allowable values of increase in the mass of the RC structure, the relationship between the duration of the applied load and fundamental vibration period of the RC structure, and the pattern of applied loads) on the accuracy of the simulated results were investigated. The accuracy of numerical simulation results has been evaluated through comparison with existing experimental data. The results of this study show that the achievement of accurate structural responses in the implicit time integration analyses using the MS method involves the appropriate selection of the effective parameters of the MS method.

The purpose of this study is to analyze the implications of the case of France, which has already implemented the social integration policy with the interest of the social integration of migrants in advance of Korea. First, we analyzed the system and system of social integration policy in France. Second, we analyzed the social integration policy promotion system in France, and examined the ministries and the agencies that direct the integration policies of the migrants. Third, the implications for the integration policy of Korean immigrants were derived through the above analysis. As a result, France was promoting a consistent social integration policy at the level of the central government, and all members of the society participated in the social integration program. It also encouraged participation in the program in conjunction with social integration programs. Based on this, we concluded that the social integration policy of our country should be modified somewhat. First, it is necessary to pursue the unity of policy by uniting the ministries that can manage migrant social integration policy in our country. Second, the main target of the social integration policy of our country should include not only immigrants who migrated from abroad but also Koreans. Third, Korea should encourage migrants to participate more in social integration programs and at the same time increase their participation rate by disadvantage of staying.

This study aims to investigate the effect of psychosocial aging on age integration and the moderating effect of Familism and Family solidarity. In particular, this study has significance for establishing a basis of practical and political intervention in family level for improving age integration. We employed data from the 'Ageing Society Awareness Investigation' funded by Korean National Research Foundation in 2014. Our analysis sample consisted of 702 adults who were from 40 to 90 years old. Also, this study conducted descriptive statistics and multiple regression analysis by using STATA13. First of all, the lower psychosocial aging awareness is the higher age integration awareness. Familism and family solidarity were not a significant predictor for age integration. However, the interaction effects between familism as well as family solidarity and psychosocial aging ware statistically associated with age integration. That is to say that as psychosocial aging is negative, when decrease age integration, the net moderating effects of familism and family solidarity were found between age integration and psychosocial aging. Based on the results, this study provides implications that reinforcing family value and promoting interaction and solidarity with family members are positively contributed to age integration awareness at this point of negative psychosocial aging.

Purpose: The purpose of this paper is to analyze the spatial configurations of a sample of Korean regional emergency medical centers (REMCs) to explore its underlying genotypes and thus produce a base line data for the analysis and evaluations of future REMCs designs using space syntax theory. Methods: Space syntax analysis was used as a major tool for the analysis and exploration of Genotype. The measures of Integration(overall integration with exterior and without exterior as well as the integration of individual clinical spaces for each center), base difference factor (DF) and Space link ratio were calculated for a sample of seven Korean REMCs. Results: The result shows a strikingly similar pattern of Syntactic measures across the sample, the mean integration of sample ranges from 0.82-0.99 with exterior (while considering the exterior space as a root) and 0.81-1.01 without exterior (considering the connections of interior spaces only with no outside connection). The base difference factor (DF) of the sample varies from 0.60-0.81 with exterior and from 0.59-0.82 without exterior. Case number-1 was identified as non-genotype with differing order of Syntactic values. Although the genotype had different forms, layouts and even sizes, these results cannot be explained by Phenotypical comparisons. Implications: This study will contribute to the configurational analysis and evaluation of existing and future Korean REMCs design and practice of emergency healthcare delivery system in Korea.

Objective : The aim of this study was to determine the priority competency by analyzing the importance, performance, and educational requirements of occupational therapists to develop a competency in performing sensory integration intervention. Methods : Occupational therapists were surveyed by gender, age, educational background, work location, occupational therapy experience, and sensory integration therapy experience. The difference was investigated through the importance-performance analysis of competency, and the priority of the competency was investigated using the Borich demand analysis method. Results : The therapists recognized professional competency as the most important, whereas performance was the least important. In all sub-competencies, the importance was high, but the performance was low. As a result, the education requirement was highest for professional competency. The importance-performance analysis revealed that professional competency was the area requiring the most urgent improvement. As a result of the Borich demand analysis, statistically significant differences between the importance of all competencies and the actual performance. The most significant difference was found in the professional competency group. Conclusion : The occupational therapists in this study who performed sensory integration interventions recognized professional competency as the most important but most lacking in actual clinical practice. The results of this study will be used as guidelines for developing competency-based sensory integrated intervention curricula.

In order to overcome social exclusion and to integrate social housing, it is necessary to plan a communal space in urban collective housing so that residents can have belonging sense and community consciousness. In this study, it is necessary to consider the linkage between social integration and residential space, and to derive the characteristics of planning the collective housing for social integration. We analyzed the planning characteristics of MVRDV's communal spaces of collective housing and suggested a method of planning communal spaces of urban collective housing for social integration. Urban density is an important tool and background for MVRDV's design methodology. For this reason, MVRDV's collective housing is selected as a case study in this study. As a result of case analysis, openness and connection characteristics should be considered by using various devices such as glass exterior, balcony, and void in planning the communal space in urban collective housing for social integration. However, since it has appeared in many cases, it can be criticized that the application of this is merely a logic. In other words, it is possible to suggest that we should actively introduce less accessible access. This problem should be solved through more case studies.
