The OSI fault management is composed of specific management functions such as the Alarm Reporting Function, Event Report Management Function, and Log Control Function. The fault management is to notify and manage the events and the alarm data which are transfered as the information of the fault management may be managed effectively. And it is necessary to design the model of the fault management properly by using these functions for the study of network management activities. Therefore, in this paper, the integrated management model of the Event Report Management and Log Control Function based on Alarm Reporting Function is investigated. Also, the system component of alarm collector which is added in the manager system for the effective fault management is studied and proposed.

Computer center of university or company manages many non fault-tolerant servers and network devices to spare expenses. Because a service fault occurs sometimes by worm virus, system bug etc, we need a technique to detect it for continuing service. This paper introduces design and implementation of the system to observe many heterogeneous services, and web-based interface improving convenience of system manager. A system fault is reported to system managers via email or SMS by introduced service observation system, not service user. Then system managers can recover the system fault by this notification and minimize a fault period.

This study investigated the effect of cash benefit and in-kind benefit policy supported by disabled children on the satisfaction of service care of main caregiver. The results of this study are as follows. First, the parental stress, parenting burden, and family members' difficulties were investigated. However, the research on the salary policy supported by the handicapped children has been scarce, and it has been found that the research on the service satisfaction of the main caregiver is also insufficient by the type of salary. The purpose of this study is to examine the effect of variables (parents gender, child gender, parents age, child age, disability grade, average income) on service satisfaction. As a result, parents age, child age, and child gender showed statistically significant effects on service satisfaction. This resulted in statistically significant overall effects on the application process, economic burden, support and selection criteria, service volume, and overall satisfaction. Based on the results of the study, the implications for cash benefits and in-kind benefits could be improved by increasing the amount and scope of benefits, and customized services considering the age of the handicapped children, ultimately improving the service satisfaction of the main caregiver.

현재 네트워크 처리 시스템의 문제점은 시스템 상태나 장애에 따른 결과를 받아서 네트워크 상태가 정상인지 비정상인지를 네트워크 운영자에게 보고하는 기능은 가지고 있지만, 장애의 기록유지와 네트워크 사용자의 문의 및 불만 상담을 처리할 수 있는 기능은 제공되고 있지 않은 상태이다. 이러한 네트워크 상에서 장애를 효과적으로 해결하기 위해서는 장애를 처리하는 네트워크 장애처리시스템(Network Trouble Management System)이 필요하다. 또한, 네트워크 장애처리시스템은 궁극적으로 네트워크 운영 방식을 획기적으로 개선함으로써 네트워크 장애로 인한 시간적, 경제적 손실을 최소화할 수 있다[1]. 본 논문에서는 장애 처리 티켓 시스템에 전문가 시스템을 접목시켜 각 분야에 고급 전문가들을 영입하고 관리할 수 있는 전문가 시스템 기반의 통합 시스템 구현함으로써 사용자에게 신뢰성 있는 고부가가치의 서비스를 제공할 수 있게 하였다.

Objectives : The aims of this study were to investigate the psychopathology in adolescents with internalizing disorder using the self-report version of Strengths and Difficulties Questionnaire (SDQ-SR) and the Minnesota Multiphasic Personality Inventory for adolescents (MMPI-A), and to explore the complementarity between these two inventories for diagnostic assessment. Methods : Ninety-one patients aged 13-17 were divided into two groups by clinical diagnosis, 44 with internalizing disorder and 47 comparison group with other disorders. The data of SDQ-SR and MMPI-A completed by them were analyzed for the ability to predict internalizing disorder. Results : The logistic regression analysis revealed that diagnostic predictability increased by 2.27 times with every 1 point of SDQ-SR emotional symptom score increment. Comparison of ROC curves for internalizing disorders showed that the SE and SP of SDQ-SR emotional symptom with score over 4 was 88.94 and 78.72, respectively. For A-anx of MMPI-A with score over 56, SE and SP was 77.27 and 74.47, respectively. However, combination of these scales could not enhance the predictability of diagnostic classification more than that of SDQ-SR emotional symptom alone. Conclusions : Emotional symptom scale of SDQ-SR and A-anx, A-aln, A and INTR of MMPI-A should be important subscales for diagnosing the internalizing disorder of adolescents, however, which needs to be examined further with a larger sample size including normal control group.

This study sought to explore the demand in the social service sector and present policy implications, focusing on the vulnerable in rural villages exposed to worse conditions amid the Covid-19 crisis. To this end, the social service needs of vulnerable groups by household type were analyzed by utilizing the raw data of the 2018 Survey on Rural Well-Being. Analysis showed that the greatest demand social services for all rural villages, the elderly, the disabled, one-person, one elderly and low-income households were income support services, while in household that included children the demand was for childcare and education-related services. The second-highest social services in terms of demand were cultural leisure vacation support services for all rural villages, healthcare-related services for the elderly, the disabled, one elderly and low-income households, cultural leisure vacation support services for households including children and daily life support services for single-person households. Based on these results, a measure was proposed to support social services, tailored to vulnerable groups in rural villages. In addition, the government's lack of a consultation system between urban and rural welfare policies, such as a basic plan for health and welfare in rural villages, led this paper to discuss the need for a feedback function and dedicated formulation of mid- to long-term policies in rural villages. It also proposed the establishment of conditions for providing customized social services for rural villages.

The study was to improve the right to the enjoyment of culture of persons with visual impairment by increasing the accessibility to art exhibitions and exploring assistive measures through needs assessment survey of persons with visual impairment on arts exhibition. We used total 83 responses collected through an online survey. The result are as follows. First, watching movies at a teather was the most frequent leisure activity among persons with visual impairment, while respondents reported attending art exhibitions as the least frequent activity. Yet, 71.1% included attending art exhibitions as one of their top 5 culture and leisure activities. Most of the respondents reported the purpose of attending art exhibitions as fun. However, a primarily visual atmosphere prevented them from visiting the exhibition. Second, persons with visual impairment preferred approaching the art to have a closer look. More than about 50% of the respondents used their residual vision. Most of the respondents reported to use more than two senses when appreciating the exhibits. Moreover, respondents reported that devices/services for multi-sensory experiences would be helpful to appreciate the art. The findings imply that the consideration of the characteristics and needs of persons with visual impairment is required for establishing the environment of art exhibitions. This could further contribute to the improvement of the right to the enjoyment of leisure and culture of persons with visual impairment and lead to the realization of social integration.

The purpose of this study was to examine music-color association response(MCAR) of people with visual impairment through music-emotion scale and music-color scale. The study was conducted on 60 participants(30 congenital/ 30 adventitious) who are using services of two welfare centers at S and B cities. For this, four basic emotions (happiness, sadness, anger, and fear) mediated by music were selected, and MCAR to emotion-inducing music were analyzed through self-report method. As a result, first, there were found contrasts in MCAR between happiness and sadness according to type of emotion, however, similar in anger and fear. Second, in MCAR among three variables of the music-emotion scale(valence, arousal and intensity), valence was congruent with MCAR according to type of emotion, arousal marked high scores in negative emotions, and scores of intensity in happiness and sadness were higher than those in anger and fear. Third, there were no significant differences between two groups of people with congenital and adventitious visual impairments. It is meaningful that this study showed the MCAR can be mediated by music through investigating those of people with visual impairment.
