  • The mechanical system of a drive can often be modeled as a two- or three-mass-system. The load is coupled to the driving motor by a shaft able to perform torsion oscillations. For the automatic tuning of the control, it is necessary to know the mathematical description of the system and the corresponding parameters. As the manpower and setup-time necessary during the commissioning of electrical drives are major cost factors, the development of self-operating identification strategies is a task worth pursuing. This paper presents an identification method which can be utilized for the assisted commissioning of electrical drives. The shaft assembly can be approximated as a two-mass non-rigid mechanical system with four parameters that have to be identified. The mathematical background for an identification procedure is developed and some important implementation issues are addressed. In order to avoid the excitation of the system with its natural resonance frequency, the frequency response can be obtained by exciting the system with a Pseudo Random Binary Signal (PRBS) and using the cross correlation function (CCF) and the auto correlation function (ACF). The reference torque is used as stimulation and the response is the mechanical speed. To determine the parameters, especially in advanced control schemes, a numerical algorithm with excellent convergence characteristics has also been used that can be implemented together with the proposed measurement procedure in order to assist the drive commissioning or to achieve an automatic setting of the control parameters. Simulations and experiments validate the efficiency and reliability of the identification procedure.

  • Starting from common sense that happiness is a state where needs are satisfied, this paper suggests the intelligence and the virtues for democratic citizens. The fact that human beings exist, relate to each other, and undertake activities which can become of moral worth when joined by autonomy, equality, and responsibility, respectively, is explained. It is also discussed that happy citizens should be able to exist autonomously in the face of political power, make an equal relationship with political power and fellow citizens, and undertake responsible activities. Lastly, it is suggested that happy citizens should be able to understand the plurality of value-contents, the similarity of value-forms, and the possibility of value-realization, and then be equipped with self-respect, mutual respect, and law-respect.

  • To date, one of the prevailing criticisms of Daniel Defoe's Robinson Crusoe has seen the adventure novel as a celebration of the rise of mercantile capitalism and the beginnings of colonialism. From this point of view, the Englishman has often been interpreted as an early embodiment of the concept of the sovereign economic subject. Prominent social critics who took up this interpretation have included Karl Marx, Max Weber, and Jean-Jacques Rousseau. Within literary studies proper, the work of Ian Watt offered perhaps the earliest version of this point of view of the novel. Influenced by both Weber and Rousseau, Ian Watt argued that Defoe's wandering protagonist embodies the rise of economic individualism. More recent criticism has tended to challenge this dominant interpretation by laying greater stress on such countervailing factors as Crusoe's mental uncertainty and inner conflict. Drawing inspiration from Fredric Jameson's diagnosis of the ills of late capitalism, this paper analyzes the ways in which Defoe's hero, rather than championing modern rationality, can in fact be seen as suffering from many forms of emotional psychosis. Robinson Crusoe can, after all, be better viewed as a contradictory multi-layered text that, despite its outward valorization of economic individualism, portrays its hero as a victim of negative capitalistic forces, a hero driven by his desire to possess but haunted by a fear of loss, a hero who flaunts inflated feelings of self-worth even as he reveals deflated notions of material insecurity and mental persecution.

  • The objective of this research is to search the solution for the difficulties of science and invention gifted middle school students with social and emotional problems that they are faced. The result of this research has shown that the gifted students were feeling difficulties of low self-esteem in their peer relationships, communication and cooperation skills. They were feeling less confident in their stress processing capacity and their multi-processing capacity. Some were also troubled with the intense expectations from their environment and theirselves which led them to feel confusion in their identities and their future. Therefore, instead of education focused on academic achievement and cognitive activity, present education for the gifted must focus on helping to solve the student's social and emotional problems and to strengthen social and emotional skills they need. To achieve this, the education for the gifted students should include a social-emotional learning program, and it should also run a continued and personalized consultation program for gifted students.

  • Currently marketing researchers are investigating the causal variables affecting to salesforces' performances. Some researchers found personal and organizational affecting variables as well as structural context of variables. But almost affecting variables examined in salesforce performance researches are personal characteristics. Such organizational variables like leadership, organization's market orientation would be worth to examine in salesforce performance researches. Thus this research is intended to analyze effects of personal and organizational characteristics on salesforces' performances. Data for this research were elicited from sales representatives of motor companies. Data collected were analyzed by regression analysis using SPSSWIN Ver.10.0. The following are major findings of this research. 1. Leadership whether transformational or transactional affected on salesforces' performances. But it was not accepted that transformational leadership would be superior than transactional leadership. 2. Market Orientation of organization affected on its salesforces' performances. 3. Personal characteristics such as need for achievement, compensation predispositon, self efficacy, learning goal orientation were affect on salesforces' performances. But it found that effects of intrinsic compensation predisposition on salesforces, performances were reverser (-). Based on the above findings, the following conclusion could be drawn: 1. Organizational variables like leadership and market orientation are key managerial variables in the sales organization, meaning that sales manager development and organization's market-driven culture are important. 2. Through recruiting and educating, raising salesforces' self-esteem is necessitated.

  • The purpose of this study was to verify the effectiveness of a life review-narrative group therapy program aimed at increasing ego-integrity in the elderly. The life review-narrative group therapy program was organized according to the tfe course from childhood to old age. The objectives of the program were for the elderly to enhance their self-worth, become aware of their individual self existence, accept aging and death, accept the past and present life, and to make the most of their experiences of overcoming difficulties. The counseling techniques used in the program were mainly reminiscence and re-authoring of the narrative therapy. Thirty-two elderly people aged 60 years and over (16 in each of experimental and control groups) were selected randomly from the Daegu Metropolitan City General Welfare Center for the research. The two groups were identified as equivalent for the study in a pre-test. The program of the experimental group was implemented twice a week for 90 minutes per session over a 6-week period (Sep. 8th - Oct. 14th. 2005). The pre (Sep. 8th 2005), the post (Oct. 14th. 2005) and follow-up (Nov. 14th. 2005) tests were implemented in ordo, to verify the effectiveness of the program. The instruments used in the study were the Ego-Integrity Scale. The data were analyzed using t-test, and Ore-Factor Repeated Measures ANOVA. The findings of the study were as follows. The experimental group evidenced significant effects on enhancing ego-integrity. The result of the post hoc multiple comparisons showed that the effects of the life review-narrative group therapy Program were maintained for one months. Meanwhile the control group did not show any significant change in ego-integrity. Based on these findings, the limitations of the study were discussed, and further research was suggested.

  • This study analysed marital comflicts, related factors, and adjustments to those conflicts described by urban Korean women. The purpose was to discover directions for resolution that would enhance the helpfulness of volunteers or prfessionals working with women in counselling settings. The investigator interviewed 20 married women, all mothers and housewives living in Seoul, attending marriage encounter programs and the Lifeline telephone counselling service. An interview schedule using six open-ended questiona guided the data colleciton which took place between May 31 and December 29, 1988. Content analysis of the data revealed, in order of reported frequency, the following areas of conflict: relationships between husband wife, relationships with children, relationships between the wife and her mother-in-Law, unsatisfied sexual needs, the husband's extra marital relationships, lack of self actualization and finacial matters. Analysis of the data suggested the following factors were related to the conflicts: reasons for marriage, traditional views about marriage and divorce including to accept a marriage arranged by the parents, the husband's traditonal attitude toward the sex role of the wife, the husband's patriarchical authoritarianism, and his attitude toward the wife;s empolyment outside the home. The women thought these conflicts severely affected their relationships within the famaily, particularly with their children. Literature suggests links with such poor parent-child-family relationships and adolescent or young people's social problems. Volunteers or professionals working with married women in counselling situation need to be conscious of the possibility of these conflict during assessment, and direct their guidance toward such conflict resolution. The researcher makes several suggestions which include the need for the husband to give emotional supports to his wife, to recognize the worth of housework, to share the work of the home, to fine ways to enhance the wife's self-actualization and to ease dreary housework routines by prviding modern appliances.

  • We have developed art and career convergence class for career recognition through drawing a neighborhood job map. Thus, we want to expand the students' career recognition. 3 Classes were conducted in 16 elementary school students from 5th to 6th. Through pre & post-questionnaire, and the interviews with the students' work, job recognition with job value and job prejudice, self-understanding and career attitude were analyzed. As follows. First, students' job recognition was expanded. The ability to identify the needs, values and purposes of jobs has improved. Changes in job values that all jobs are worth have occurred and job bias has changed. Second, the career attitude changed on the basis of self-understanding. Thus, in the context of deciding the job demanded by the society rather than the student's will, art and career convergence class was effective in career recognition.

  • Under the inhumane oppression of imperialism, the Third World's political violence has been often represented as an immediate and explosive one with an instant, concentrated visibility. Yet the ecological and psychological exploitation of the Third-World countries by empires, as Rob Nixon insists, shows the relative invisibility of slow violence. This paper is to reveal this slow violence of the marginalized areas symbolized as the lowland. Although Arne Naess' deep ecology promotes the inherent worth of living beings regardless of their instrumental utility to human needs. this paper deals with three postcolonial ecological textbooks which criticize the white-centered deep ecology: Amitav Ghosh's The Glass Palace, Jhumpa Lahiri's The Lowland, and Barbara Kingsolver's The Poisonwood Bible. Through postcolonial critical study, this paper finds out that all these three works have some themes in common. First, these postcolonial works assume a shape of family saga which is parallel to the slow violence of ecological and psychological plundering of empires in the postcolonial countries. Second, like the mangroves which have a tenacious hold on life, these postcolonial people rather overcome the heterogenic challenge with the sturdy and tough mind than defeated. Third, the native people's ethics of earth functions as the stronghold for their respectable lifestyle in their indigenous historicity. Finally, as a big fat brother, the Americanized globalization or neoliberalism is warned as the neocolonialism which is often shown as the disguised pattern of greenwashing. Namely, the people's self-enhancement is always prior to the imperialistic development or neoliberalism in the postcolonial ecological texts which sharply contrast the native's life consciousness and the empire's development theory.

  • Recently, the Korean government announced that it would focus on fostering intrapreneurship and corporate spin-off. The government encourages intrapreneurship because it ultimately seeks to develop industries and markets, grow innovative companies, and job creation. In particular, the government believes that enhancing intrapreneurship will reduce the personal fear of failures, expand open innovation by utilizing resources within existing companies related to innovation creation, and lead to new start-ups. Accordingly, this research reviewed the previous studies on corporate entrepreneurship activities and entrepreneurial self-efficacy and briefly looked at the status of global intrapreneurship activities. Based on the Global Entrepreneurship Monitor Adult Population Survey data in 2015, this study conducted a logistic regression analysis with the data of 27 OECD member countries' and Korean respondents. The finding confirms that the personal experience of intrapreneurship could be positively associated with entrepreneurial self-efficacy of the person. Therefore, it seems to be worth for the Korean government considering policies that support intrapreneurship as part of the start-up policy.
