  • This study proposes a new approach to analyze the impedance and the elasticity of a serial chain of spring-damper system, areal-time collision-free trajectory generation algorithm is proposed. The reference points on a trajectory connected by the spring-damper system have a mechanism for self-position adjustment to solve a collision problem by the impedance, and the local adjustment of each reference point is propagated through the elasticity to a real robot at the end of the spring-damper system. As a result, the overall trajectory consisting of the reference points becomes free of collision with environmental obstacles and efficient having the shortest distance as possible. In this process,, the reference points connected by the spring-damper system take role of virtual robot as global guidance for a real robot, and a cooperative is carried out by the system of robots. A control technology is proposed to implement for mobile robot.

  • This paper examines whether me effects of product demand shocks on employment are different between unionized and non-unionized firms, using new firm-level longitudinal data in Korea over the period 1997~2004. The estimation result shows that the effects of both negative and positive demand shocks on employment are smaller in unionized firms than in non-unionized firms. The result implies that unions appear to provide their members with job stability in response to negative demand shocks, while playing a very limited role in employment determination in response to positive demand shocks leading to employment expansion.

  • Applying effective coping strategies and reducing powerlessness for the chronic pain adjustment of musculoskeletal patients were researched for basic data in the development of nursing intervention. The subjects were 99 musculoskeletal patients with chronic pain. Data was gathered with direct interview using a questionnaire. With the SAS tool. data were analyzed for percentage. Pearson correlation. t-test. and ANOVA according to characteristics of variables. Internal consistency(alpha) coefficients were .91 for coping scales and .71 for powerlessness scales. The results are as follows: 1. Pain duration was mainly 6 - 12 months(52. 5%). 2. Primary pain site was mainly lower limbs(58.6%) and pain severity was a moderate level. 3. The preference of coping strategies was decreased in the order named in resting. seeking social support. exercise or stretch. guarding. and asking for assistance. 4. The longer pain duration. the more the coping strategies of asking assistance used. This was stastically significant(F=3. 35. p<.05). 5. The group with the experience of hospital admission was more powerless than the group without that(F=3. as. p<.01). 6. Pain severity and powerlessness were significantly positively correlated(r=.444. p<.001). Coping strategy applying and powerlessness were significantly negatively correlated(r=-. 288. p<.01). In consequence. the nurse should playa role as the supporter of patient's maximal usage of his resources in pain relief. adjustment, and control. The nurses should also develop for the nursing intervention of physical therapy and educational programs.

  • Anxiety is one of the basic human emotions. From the evolutionary psychology point of view, it is a necessary factor for survival and prosperity of human beings that had been developed throughout time with the history of human survival and development. Anxiety plays the role of protecting one from social or physical threats. In reality, lacking of anxiety showed lots of examples of maladjustments. But the result of over-adjustment, which is overanxious disorder, is definitely disturbing one's survival and growth, and it can lead to anxiety disorder that needs to be treated. Anxiety from the evolutionary psychology point of view, started as a primary adjustment form and it evolves into various types of anxiety disorders that relates to the modern society's characters. Therefore, having the grasp of evolutionary psychology, which can be the base of treating anxiety and anxiety disorders, is very important. So from now on, studies for this aspect would need to be done as integrated and multidisciplinary studies not only by psychiatrists, but by including epidemiologists, psychologists, ecologists, biologists, and neuropsychologists. In this article, the author tried to review and explore the idea of anxiety and anxiety disorders from the evolutionary psychology point of view.

  • Purpose: This study examined the effects of a gender-friendly environment and the communication competence of male nursing students on college life adaptation. Methods: The participants included 221 male nursing students from the nursing departments at five universities. Data were collected using self-report questionnaires and analyzed using descriptive statistics, independent t-tests, one-way ANOVA, Pearson's correlation coefficients, and multiple regressions with SPSS/WIN 18.0. Results: The participants' scores on the gender-friendly environment, communication competence, and college life adaptation were 58.41±10.96, 56.19±7.32, and 117.37±16.86, respectively. Factors influencing male nursing students' college adaptation included satisfaction with major, communication competence, academic grade, and economic level. These variables together explained 59% of college adaptation in male nursing students (F=26.74, p<.001). Conclusion: The findings demonstrate that the development and application of educational programs for communication competence and a gender-friendly educational environment are essential in enhancing the adaptation of male nursing students to college life.

  • Purpose: This study aims to analyze the distribution of the role of adversity quotient in the estimation bias of future earnings. Adversity quotient is a cognitive ability that can be distributed as a reducer of bias effects that occur in profit forecasting or investment decision making. Research design, data and methodology: The study designs a full factorial within-subject 2×3 as a laboratory experiment. The study subjects are 30 accounting students who are proxied as investors. Results: The results show that the estimated earnings made by investors experience anchoring-adjustment heuristic bias which means the initial value becomes a basic belief that influences the decisions taken by investors. However, this study also provides evidence that heuristic bias can be reduced by the presence of adversity quotient. Investors who have high adversity ability are abler to reduce the estimation bias when compared to investors who have medium and low adversity ability so the higher the difficulty ability possessed by investors, the less likely the occurrence of bias in decision making. Conclusion: Thus, the adversity quotient is proven to be distributed as a reducing opportunity from the bias that will occur in estimating future earnings or making investment decisions.

  • Purpose: The purpose of the study was to explore and describe the experience of adult Korean children who are caregivers for parents institutionalized with dementia. Methods: Participants were fourteen adult children caregivers of elders institutionalized with dementia. Data were collected through in-depth unstructured interviews with individual participants from August to November, 2012. Theoretical sampling was used to the point of theoretical saturation. Data were analyzed using Strauss and Corbin's Grounded Theory Method. Results: From open coding, 67 concepts, 29 sub-categories, and 14 categories were identified. Analysis revealed that the core category of the experience of adult children caring for their parents institutionalized with dementia was 'enduring the role of a prop' consisting of four phases: initial turmoil, exploration, role adjustment, and acclimation. To manage the role of a prop, participants utilized various action/interactional strategies such as overcoming the unfamiliarity, overseeing the nursing home care, and counterbalancing the caring roles. As a result, participants experienced ambivalence towards the existence of parents with dementia, changes in family relationships, altered viewpoint towards nursing homes, and restructuring of life. Conclusion: In-depth understanding of the experience will guide nurses to promote effective interventions in order to better support the Korean family caregivers of parents institutionalized with dementia.

  • The purpose of this convergence study was to evaluate the influence of interpersonal problems on sleep quality in college students and to analyze the mediating role of mental health and the moderated mediating role of emotional regulation. This was a cross-sectional study of 307 students at a college in Seoul. The results of hierarchical linear regression showed that interpersonal problems and mental health were statistically significant predictors of sleep quality in college students. A mediation analysis further revealed that students' mental health mediates the relationship between interpersonal problems and sleep quality. Additionally, there was a moderated mediating role of dysfunctional emotional regulation in this process. Our findings suggest that supportive and adaptive cognitive emotional regulation educational programs should be designed based on college students' maladaptive emotional regulation experiences and individual characteristics.
