One of the main chalenges in personal communication services (PCS) is to locate many mobile terminals that may move frequently from place to place. Such a system operation is called location management. Many network signaling traffic, and database queries are required to achieve such a task. Several strategies have been proposed to improve the efficiency of location management. These strategies use location register databases to store the current location on mobile terminals, and are vulnerable to failure of the location registers. In this paper, we propose a fault-tolerant pointer forwarding with distributed home location register (FT-RFDHLR) to tolerate the failure of location registers. The performance of the proposed method is evaluated by an analytical model, and is compared with thew pointer forwarding with the single home location register (PFSHLR), the pointer forwarding with distributed home location register (PFDHLR), Biaz's bypass forwarding strategy (BFS) and two-path forwarding strategy (TPFS).

Purpose: This study is to understand how community members perceive past life recollection and preparation for death. Methods: Using a questionnaire, we surveyed 160 adult residents of one of the districts (gu) in Seoul, Korea. Descriptive statistics were used. Results: Participants chose their 30s and 40s as the most difficult time in their lives. The most painful experience was "an illness of a family member", followed by "trouble with a spouse", and "trouble with children". As for the most difficult social experience, "sense of loss in life" was ranked the highest. Personally, the happiest time was "accomplishment of a goal", while it was "happiness through children" in family relationship and "contribution to society through my career" in social life. As for the most regrettable experience, personally "having lived without purpose" was the highest, "not meeting my parents' expectation more" in family relationship; "not providing sufficient education" in relationship with children; "not having an occupation that I wanted" in work life, and "lack of social skills" in social life. More than 87% of the surveyed showed a positive attitude about the system of the do not resuscitate (DNS) order. For a situation where participants were supposed to have an incurable disease, "I want to be notified of the true condition" and "I want to write a will and advanced directives" ranked high, receiving more than 3.1 points out of 4. Conclusion: These results demonstrate the need for death education to provide people with an opportunity to accept their regrettable experiences in the past as part of their life. Also, this study suggests the importance of writing advanced directives for people to prepare for "death with dignity" how it can help their decision to be better respected.

The government budget for promoting startup have been skyrocketed as catching up with increasing demands for high-tech startup by disruptive innovation resulted from rapid technology change. However, major trend of startup have still fallen on self-employed type of startup due to the lack of expertise and fund in spite of desperate government policy efforts. In reality, the access to high-tech startup has been very limited and too high huddle to would-be entrepreneur. This paper implement empirical analysis on the effects of entrepreneur competency and satisfaction level to government support, considering these as the KSF for the growth and success of high-tech startup, to the performance of the company. In particular, it focus on defining unique characteristics of high-tech startup through differential proving by the backgrounds of entrepreneur such as major, R&D experience, patent possession, CTO possession. This research carry out survey to 217 entrepreneurs in high-tech company in Daejon and Daegue at R&D Special Innopolis Zone. Research results are as follow. First, entrepreneurial achievement competencies, conceptualization competencies, network competencies and market recognition competencies positively affect the financial and non-financial performance and organizational and technical competencies, while organizational and technological competencies only positively impact on non-financial performance. Second, the satisfaction level of government support showed a positive moderating effect on entrepreneurial achievement competencies and financial performance, while no significant effect in other competencies. Third, positive differential effect by the technological background of entrepreneur such as Major, R&D experience, patent possession, CTO possession) have been confirmed. This paper deliver several significant implications and contributions, First, it propose classified and systematized entrepreneur competency through the domestic and foreign literature reviews. Second, it proves the need for the wider spread of team based startup culture rather then sole startup. Third, it also proves the important role of technological background of entrepreneur among the characteristics of high-tech startup.

An unusual success engendering loyalty among cult fans in the United States, Mamoru Oshii's 1995 cyberpunk anime, Ghost in the Shell (GITS) revolves around a female cyborg assassin named Motoko Kusanagi, a.k.a. "the Major." When the news came out last year that Scarlett Johansson was offered 10 million dollars for the role of the Major in the live action remake of GITS, the frustrated fans accused DreamWorks of "whitewashing" the classic Japanimation and turning it into a PG-13 film. While it would be premature to judge a film yet to be released, it appears timely to revisit the core achievement of Oshii's film untranslatable into the Hollywood formula. That is, unlike ultimately heteronormative and humanist sci-fi films produced in Hollywood, such as the Matrix trilogy or Cloud Atlas, GITS defies a Hollywoodization by evoking much bafflement in relation to its queer, posthuman characters and settings. This essay homes in on Major Kusanagi's body in order to update prior criticism from the perspectives of posthumanism and queer theory. If the Major's voluptuous cyborg body has been read as a liberating or as a commodified feminine body, latest critical work of posthumanism and queer theory causes us to move beyond the moralistic binaries of human/non-human and male/female. This deconstruction of binaries leads to a radical rethinking of "reality" and "identity" in an image-saturated, hypermediated age. Viewed from this perspective, Major Kusanagi's body can be better understood less as a reflection of "real" women than as an embodiment of our anxieties on the loss of self and interiority in the SNS-dominated society. As is warned by many posthumanist and queer critics, queer and posthuman components are too often used to reinforce the human. I argue that the Major's hybrid body is neither a mere amalgam of human and machine nor a superficial postmodern blurring of boundaries. Rather, the compelling combination of individuality, animality, and technology embodied in the Major redefines the human as always, already posthuman. This ethical act of revision-its shifting focus from oppressive humanism to a queer coexistence-evinces the lasting power of GITS.

Media coverage of depression, the mental disorder, is on the high rise following the soaring number of reported celebrity suicide. This study is an exploratory attempt to get a glance on how online news media are portraying depression. The content analysis results indicate that celebrity was the most cited source, outnumbering the others such as non-celebrity patients and experts. More than half of the sample attributed the cause of depression to socio-psychological factors. Medical consultation was the most reported means of treating depression among the sample, while over the half did not suggest any treatment methods at all. Overall, celebrity related news were less likely to talk about the cause and treatment methods. In addition, the more neuro-biological factors were designated as the main cause of depression in the articles, the more chances of treatment method of all kinds were brought up. The frame of human interest dominated a little less than half of the articles examined, and only few reported positive outcome or achievements after coping with depression.

The everyday life of police officers requires them to face a number of criminal acts and enter compromising crime scenes. In this case, officers may be compelled to make a personal expression of negative emotions. Negative emotions of members confidence for effective job processing and contributions duties and achievement of the job within the marine police force. Therefore, to control the emotive dissonance of organization members is a great help to the development of the organization. This study focuses on emotional dissonance among marine police officers to verify the impact of this dissonance on job burnout and consider the mediating effect of emotional intelligence. Research results are as follows: First, the relationship between emotional dissonance sub-factors and job burnout among marine police officers was studied. It was found that marine police did not feel emotionally jarred because they consciously tried to abstain from emotional engagement, but this was found to reduce emotional intelligence as related to desired emotions as well. Second, Emotional intelligence of the Marine Police was found on a significant impact on job burnout. Third, the impact of emotions in relation to emotional dissonance that job burnout of marine police intelligence officials confirmed that there is a statistically significant mediating effect. Finally, in a comparison of direct effects versus mediated effects, marine police were seen to be prone to emotional dissonance and experienced job burnout as a direct result of applying greater emotional intelligence.

This study aims to find out the determinants of burnout in order to better understand the burnout process among social workers. For this purpose, a hypothetical model which explains the relationships among 8 job-related stressors (role ambiguity, role overload, difficulties in solving problems of clients, conflict with the clients, lack of support from the supervisor, closed communication pattern, bureaucracy, and lack of accountability), 4 mediators (job-stress, professional role performance, abiding by the agency policy and partiality in service delivery), and 4 dimensions of burnout (physical exhaustion, psychological exhaustion, depersonalization and personal accomplishment) was developed. Using the data collected from 207 social workers, the hypothetical model was tested. For data analysis, a path analysis was used, and the best-fitting model was found(df=66, $x^2$=63.250, GFI=0.962, CFI=1.00). As a result of this study, the following results were found. Burnout among social workers was increased by the 6 job-related stressors(role ambiguity, role overload, difficulties in solving problems of clients, conflict with the clients, lack of support from the supervisor, closed communication pattern). Job-stress, the mediating variable of the emotional path to burnout, increased professional role performance and the abiding by agency policy, and finally increased burnout. On the other hand, professional self-efficacy (which consists of professional role performance, abiding by agency policy and partiality in service delivery), the mediationg variable of the cognitive path to burnout, reduced burnout when the professional role performance was high, and abiding by agency policy and partiality in service delivery were low.

In this study, we examine the mediating effect of resilience on the relationship between grit and self-determination in college students in order to provide basic data for ensuring the positive development required for college students to understand their collective, as well as their individual, abilities. This study comprised college students sampled from three cities in Chungcheong province: Daejeon, Sejong, and Cheonan. The collected data were analyzed using AMOS 22.0 statistical software. The results of this study are as follows. First, firmness of mind and courage in the face of hardship (based on the resilience of college students) was found to have a statistically significant, positive effect on that resilience. Second, this grit in college students has a statistically significant, positive effect on their self-determination. Third, the resilience from college students' self-determination revealed that resilience has a statistically significant, positive impact on their self-determination. Fourth, we found after verifying the mediating effect of resilience in the relationship between grit and self-determination of college students that resilience has a mediating effect in the relationship between grit and self-determination. This study is significant in that it provided empirical grounds for self-determination in college students by identifying the relationship between the motivational variables affecting their self-determination.

In this study. 'extended science investigation' was conceptualized as a comprehensive science investigation contrasted with exercise of process and skill component and cookbook style experiment. The extended investigations should be pursued for giving opportunity of more authentic science activities in school science. And one of important educational objectives in students' science investigations is to achieve motivation for investigation which drives and triggers further investigations. It can be discerned as positive and negative by its direction and also as internal and external by its cause. The purpose of this study was to describe change of students' motivation for investigation while they were performing the extended science investigations. The subject was 128 7th grader attending coeducational school in Seoul. Questionnaires and students' reports were analysed complementarily to describe students' motivation for investigation. The number of students who showed positive motivation for investigation did not increase in the developed extended investigations than in the directive investigations in textbook, but the cause of positive motivation for investigation has changed largely from task-exclusive factors to task-inclusive factors. In case of negative motivation for investigation, regardless of the kind of investigation task, task-inclusive factors were recognized as the main causes. Among those whose motivation changed during successive extended investigations, the students who showed change from negative to positive were more than the reverse. And the number of positive intrinsic motivation for investigation was increased at the second half of the extended science investigations. So it can be said that there was a desirable change of motivation for investigation at the second half the extended science investigations.

Among many factors that affect the development of the talent of gifted children, the family factor that first finds and cultivates the talent of gifted children is quite important. The researches on the family of gifted children are mostly concentrated on physical environment out of the home environment, neglecting psychological environment. Although the recreational activity of family with gifted children considerably contributes to the emotional, intellectual and social development of gifted children themselves and to the improvement of life quality of the family members, the recreation of family with gifted children has not yet been studied. Thus, the objective of this research is to present basic materials for seeking the direction to educate parents and to support family with gifted children in order to encourage synergy effect in emotional and social growth of family with gifted children by surveying the property of recreation of family with gifted children. The result of result is as follows. First, the type of family with gifted children tends to be remarkably biased to 'family-oriented activity' and 'elf-development activity.' Second, verifying the significant level of motive for recreational activity of family with gifted children at the variables such as number of family members, parents' age, parents' education level, parents' occupation, etc, it was concluded that they were not statistically significant. The result of this research suggests that education and support for efficient recreation of family with gifted children is necessary to achieve healthy talent of gifted children.
