As a demand of mobile network is increasing, mobile support protocols are suggested. Although HMIPv6 managing the micro mobility with MAP suggests a plan for an effectively mobile support, there has a problem of traffic concentrating. This paper propose efficient schemes of distributing the traffic concentrated on hierarchical Mobile IPv6. This proposed schemes, selecting MAP more than two, are divided by selected 'Active' and 'Passive' MAP. The proposed schemes change a state in MAP and define performance to distribute a load in MAP as the Load is occurred by traffic.

Purpose: The purpose of this study was to develop a Coping Scale for Infertility-Women (CSI-W). Methods: The initial items were based on an extensive literature review and in-depth interviews with seven infertile women. Forty-three items were derived from a pilot survey. Data were collected from 216 women who had experienced intrauterine insemination (IUI) and in-vitro fertilization (IVF) more than once. The data were analyzed to verify the reliability and validity of the scale. Results: Seven factors containing 28 items (four factors containing 17 items for active coping and three factors containing 11 items for passive coping) were extracted from the exploratory factor analysis to verify the construct validity. The four factors of active coping were confrontation, self-control, seeking social support (spouse), and seeking social support (colleagues and experts). The three factors of passive coping were distancing, escape, and avoidance. These items were verified through convergent, discriminant, and concurrent validity testing. The internal consistency reliability was acceptable (active coping: Cronbach's α = .78; passive coping: Cronbach's α = .81). Conclusion: As its validity and reliability have been verified through various methods, the CSI-W can contribute to assessing the coping strategies of infertile women.

Because of economic polarization and difficulties, extreme personalization, and the complexity of social relationships, modern people are experiencing various mental disorders or pathologies. Accordingly, there is an urgent need to prepare more active countermeasures and support those with mental health difficulties to improve mental health and prevent abnormal pathologies. Artificial intelligence (AI) is expected to improve the mental health of individuals through emotional enhancement beyond affective computing. We investigated how to use AI to prevent and diagnose mental diseases or disorders, support treatment, and manage followup. In particular, promising services that can be used in daily life or medical clinics were discovered and active directions for realizing these services are suggested.

Social media such as Twitter and Facebook have become popular. In the age of social media, many people have become more active online. For example, about half of all global active Internet users are on Facebook (Perry 2012). Personal branding is a very important strategy to build on an individual's strengths, and this kind of branding is expected to contribute to self-actualization. Therefore, the presence of mentors who advise users to discover their own strong points for self-actualization is necessary. In this paper, we propose a personal branding support service, Mentors, which connects mentors and mentees. The core concept is: "Everyone has the face of both a mentor and mentee." The key function is sharing stages of self-analysis in human life design: Determining value, creating a mission, and forming a strategy. From this function, a good match between a mentor and mentee can be found. The program aims to improve human life by understanding the client's strengths and using social media effectively. Future work includes launching Mentors and evaluating its service.

Supporting object group on distributed object system give merits such as load balancing, fault tolerance and high availability. In this paper, we describe a CORBA ORB that has been designed to support object group based on active replication. The ORB supports the operational model in which it uses the IIOP for communication between client and server and total ordered multicast protocol for consistency control among group members. And through extension of ORB, it provides functions required for support of object group. Since it provides transparency of object replication, the ORB is interoperable with the existing CORBA products. It make possible for existing server application to be easily extended to application supporting object group as adding interface functions which should be used for building applications is minimized. A prototype is implemented, and performance of the replicated object group is tested and compared with a single object invocation.

Detection and classification of undersea mines in shallow waters using active sonar returns is a difficult task due to complexity of underwater environment. Support vector machine(SVM) is a binary classifier that is well known to provide a global optimum solution. In this paper, classification experiments of sonar returns from mine-like objects and non-mine-like objects are carried out using the SVM, and classification performance is analyzed and presented with discussions depending on parameter values of SVM kernel functions.

The financial MyData service has implemented in January 2022 and launched 45 services by banks, securities, credit cards and fintech companies. This study applied the Q methodology, to identify the user types of MyData services and compared the perceptions of employees of financial institutions who plan and develop the MyData services. There are three types of MyData service users: active users, limited users who focus on consumption and asset status inquiry, and sensitive users for personal information. There were two types of recognition of financial company employees. One is the active user support other is the sensitive user for personal information support. The analysis of subjective perceptions can be used as a reference for establishing a company's MyData service marketing strategy and establishing related policies to improve the MyData ecosystem.

Rain-wind induced cable vibration can cause serious problems in cable-stayed bridge. External dampers attached to the cables have become widely accepted as an effective means for stay-cable vibration suppression. For very long stay-cables, however, such damper systems are rendered ineffective, as the dampers need be attached near the end of cables for aesthetic reasons. A recent study by the authors proposed that a movable anchorage system is replaced direct fixed support of the cable with a support through a bearing and damper. This paper extends the previous work by adding active control system to mitigate the cable vibration. The response of a cable with the proposed active control system is obtained and then compared to those of the cable with and without an external passive damper. The results show that the active control system can provide superior protection than the passive control system for a cable vibration.

Purpose: The purpose of this descriptive study was to identify factors influencing pulmonary tuberculosis patients' self-care behaviors. Methods: The patients were 125 adults over the age of 19 who were diagnosed with pulmonary tuberculosis, receiving care at the National tuberculosis hospital. The survey questions measured family support, multidimensional scale of perceived social support (MSPSS), stigma and self-care behaviors. Results: The average score for self-care behaviors was 3.91, ranging from 2.22 to 5.00. There was a significant positive correlation between self-care behaviors and support system. There was a significant negative correlation between self-care behaviors and stigma. The significant variables influencing self-care behaviors were family support (β = .33, P< .001), smoking (β= -.23, p= .002), age (β= .22, p= .005) and experience of stopping treatment (β= -.17, p= .040). These factors explain 36% of pulmonary tuberculosis patients' self-care behaviors. Conclusion: Family support is very important to improve selfcare for tuberculosis patients. However, those in their fifties, men, and those who do not have a job and have underlying diseases have low family support, so they need active support at the national level. The study results suggest that a educational and nursing programs must be designed to reduce stigma and promote support system in order to enhance self-care behaviors.
