Inclusion and exclusion is used in many papers to count certain objects exactly or asymptotically. Also it is used to derive the Bonferroni inequalities in probabilistic area [6]. Inclusion and exclusion on finitely many types of properties is first used in R. Meyer [7] in probability form and first used in the paper of McKay, Palmer, Read and Robinson [8] as a form of counting version of inclusion and exclusion on two types of properties. In this paper, we provide a proof for inclusion and exclusion on finitely many types of properties in counting version. As an example, the asymptotic number of general cubic graphs via inclusion and exclusion formula is given for this generalization.

Purpose - This research aims to investigate the influence of social exclusion on conspicuous consumption. Specifically this research suggested that the influence of social exclusion on conspicuous consumption would be different depending on consumers' psychological characteristics such as internal attribution tendency and self-esteem. Design/methodology/approach - The experiment was conducted to verify hypotheses. 110 sample data were collected from the experiment and SPSS PROCESS Macro was used for data analysis. Findings - The result revealed that the interaction effect of social exclusion and internal attribution was significant. Specifically, social exclusion had on positive impact on conspicuous consumption for consumers with high level of internal attribution tendency. In addition, conspicuous consumption was pronounced for consumers having both high level of internal attribution and low level of self-esteem.

This study was conducted to examine the latent classes in social exclusion and to analyse empirically the effects on the economic instability of old age by this type. And it also sought to look at whether the influence of old age anxiety varies with the subjective class consciousness of the elderly. Using the 14th data from the Korea General Social Survey (KGSS) in 2016, 1,041 adult males and females aged 18 years old were analyzed at the time of the survey. T-test, potential layer analysis (LCA), and multinomantic analysis of potential groups were conducted using the STATA14 and MPLUS 7 statistical programs. Finally, multi-regression analysis was performed to identify the moderate effect and effects among variables. According to the research, the types of social exclusion were three groups, followed by social exclusion group (49.3%), Multi-dimensional exclusion group (30.9%), and active social participation group (19.7%). The social exclusion group has the lowest possibility of economic, employment, and health exclusion, but the exclusion of formal and informal social activities seem to prominent, and the multi-dimensional exclusion group is more than 50% likely to experience exclusion in all areas. Active social participation are characterized by very active participation in informal social activities. By conducting multinominal logistic regression, it was observed that the social exclusion group included more young people than other groups, and that the multi-dimensional exclusion group included many elderly women without spouses. Finally, multiple regression analysis showed that social exclusion type interacts with subjective class consciousness and affects economic anxiety of old age.

The purpose of this study was to examine the effects of maternal rejective parenting behaviors and preschoolers' aggression and social skills on preschoolers' exclusion by peers. Subjects were 91 5- to 6-year-old preschoolers(49 boys, 42 girls) and their mothers. Data was analyzed by descriptive statistics, correlation analysis and stepwised multiple regression analysis. The major findings are summarized as follows: (1) preschoolers' exclusion by peers was positively correlated with maternal rejective parenting behaviors and preschoolers' aggression. On the other hand, preschoolers' exclusion by peers was negatively correlated with preschoolers' social skills. (2) The most influential factor on preschoolers' exclusion by peers was preschoolers' cooperative behaviors, and the next influential factor on preschoolers' exclusion by peers was maternal rejective parenting behaviors. In conclusion, maternal rejective parenting behaviors and preschoolers' social skills influence preschoolers' exclusion by peers.

This study examines cognitive impairment, which is one of the results from social exclusion and leads to logical reasoning disorders. This study also investigate how cognitive errors called abductive inference error occur due to cognitive impairment. Present study was performed with 81 college students. Participants were randomly assigned to the group who has experienced social exclusion or to the group who has not experience the social exclusion. We analyzed how the degree of error of abductive inference differs according to the social exclusion experience. The group who has experienced social exclusion showed a higher level of abductive inference error than the group who has not experience. The abductive condition inference value of the group who has experienced social exclusion was higher in the group with the deduction condition inference value of 90% than in the group with the deduction condition inference value of 10%, and the difference was also significant. This study extended the concepts of cognitive impairments, escape theory, cognitive narrowing which are used to explain addiction behavior to human cognitive bias. Also this study confirmed that social exclusion experience increased cognitive impairment and abductive inference error. Future research directions and implications were discussed and suggested.

The mutual exclusion (MX) paradigm can be used as a building block in many practical problems such as group communication, atomic commitment and replicated data management where the exclusive use of an object might be useful. The problem has been widely studied in the research community since one reason for this wide interest is that many distributed protocols need a mutual exclusion protocol. However, despite its usefulness, to our knowledge there is no work that has been devoted to this problem in a mobile computing environment. In this paper, we describe a solution to the mutual exclusion problem from mobile computing systems. This solution is based on the token-based mutual exclusion algorithm.

This study concerns the understanding of 'social exclusion' which is getting poplular in Europe as the new term or paradigm in order to resolve poverty problem. As case study on the France, the purpose of this study is to extract the consideration of welfare policy and suggestions as to us. In order to understand comprehensively the concept 'social exclusion' and the situation of the France, this study analyzes the existing researches on its concept and tries to realize a comparative study. Thus, this study indicates that the France is the state which has taken the most interest in 'social exclusion'. The second parti of this study concerns the change of the concept 'social exclusion' and its policies in the France. The concept 'social exclusion' which has used in the 1960's, has settled as the term of policies in the 1980's, thanks to seriousness of poverty and unemployment problem and change of social consciousness (opinion). As policy on the 'social exclusion', there are Revenu minimum d'insertion of the 1988 and law on the social exclusion of the 1998. Through analysis of policies on the 'social exclusion' in the France, we can get the following consideration of welfare policy and suggestions: on the macro level, the necessity to establish the comprehensive perspective on the poverty problem, invention and development of the term as regard to social new problem; on the micro lever, planning of welfare program according to clients needs, importance of perpetual assessing of the existing welfare program and institutions, the institutional establishment of 'reserve budget', the application of decentralization principle and the active participation of the private sector in order to promote the effectiveness and the efficiency of the program and institutions.

This study was to develop the indicators for understanding social inclusion exclusion of the dwellers living in permanent rental apartment, and to present a important base about priority order of national housing policy for social inclusion. The ultimate purpose of this study was to provide basic information for the development of permanent rental apartment renewal techniques. The first phase of the study was to review of the social inclusion exclusion indicators mentioned in the literature. The indicators of EU (2001, 2006), KIHASA (2005), and Jehoel-Gijsbers & Brooman (2007), which were applied in many studies about social inclusion, or included various items about dwellers' subjective attitudes, were selected to construct the framework for the study. On the basis of 3 kinds of indicators at the above, the dimensions of social inclusion exclusion were categorized as material deprivation and access to social rights in an economicstructural exclusion view, and social participation and cultural normative accommodations in a socio-cultural exclusion view. And then, the domains of social inclusion exclusion were decided as follows: income, employment, education service, housing, health, family networks and social networks. The detail contents of indicators were adopted from the prior studies as many as possible, and the dwellers' subjective attitudes and housing domains were intensified with reference to UN housing rights and the study of "residents' satisfaction of housing facilities living in permanent rental housing". The developed indicators were modified through the advisory committee that consist of the specialists from the various fields of studies. The final indicators that were overlapped or not able to be measured were eliminated, and added, in a housing domain, the standards of convenient facilities, the management condition, safety, location, crime and etc. in the apartment complex, which were required to complement in the advisory committee.

The star tracker detects microscopic star light in space and compares it with a stored list of stars to calculate the satellite's position in the inertial coordinate system. If other light, such as the sun or the earth, enters the optical head, the star cannot be recognized and the star tracker cannot be operated. In particular, strong light such as the sun affects not only operation but also the performance of the star tracker. The sun exclusion angle of the star tracker is one of the important factors determining the performance of the star tracker. This paper performs the verification of the star tracker's sun exclusion angle. In order to verify the sun exclusion angle, we predict the sun exclusion time of the star tracker and compare it to the actual sun exclusion time of the GEO-KOMPSAT-2A star tracker. In addition, the performance of the star tracker is analyzed for normal operations against the sun exclusion in the optical head. It shows that the actual sun exclusion is maintained under the range of 26 degrees, the performance requirement of the star tracker, and the star tracker operates normally in spite of the sun exclusion.

The purpose of this study was to investigate the social exclusion of 'Da-Ka-Gu' rental housing and permanent rental apartments and to provide basic source of their socio-demographic characteristics and actual conditions of social exclusion. Self-administered questionnaires and interviews were carried out with 212 dwellers in 'Da-Ka-Gu' rental housing and permanent rental apartments in the city of Gwangju from July to October of 2010. The main findings are: 1. The social exclusion of physical deficiency dimension composed of income and employment has been found to be the most serious level, compared to all the other dimensions. 2. The social exclusion from health has been found to be the highest level in the dimension of the approach to social rights. The next highest level has been found to be the social exclusions from residential areas and education and service areas. 3. The level of social exclusions from the areas of family relations and social relations, which are in the dimension of social participation, has been found to be next highest to the level of physical deficiency dimension. 4. The level of exclusion from cultural and normative integration has not been found to be of significant difference between the two types of residence in this study. This study of the actual conditions of social exclusion among residents living in 'Da-Ka-Gu' rental housing and permanent rental apartments suggests the necessity and some practical implications for policy measures of social integration for the residents of lowincome housing.
