  • The interactions between people who do not know each other have been greatly increased with the on-going increase of people's cyberspace activities. In this situation, there exist potential risk factors such as the possibility of fraud, so we need a method to reduce or eliminate those risk factors. Concerning this necessity, rating systems are widely used, and many trust metrics calculated from rate values that people give to each other are proposed to help them make decisions. However, the trust metrics decrease the accuracy, and this is caused by the different rating scales and ranges of each person. So, we propose a fuzzy adjustment method to solve this problem. It is possible to catch the exact meaning of the trust value that each person selects through applying fuzzy sets, which improve the accuracy of the trust metric calculated from the trust values. We have applied our fuzzy adjustment method to the TidalTrust algorithm, a representative algorithm for calculating the local scalar trust metric, and we performed an experimental evaluation with four data sets and three evaluation methods.

  • Purpose: The purpose of this study was to compare psychosocial adjustment in children aged 4-11 years with cancer between on and off treatment. Method: The data was collected from parents of children with cancer through interviews with structured questionnaire at the pediatric outpatient department and inpatient ward of one university hospital located in Seoul. The instrument were the Child Behavior Check List(CBCL) developed by Achenbach(1991) and revised to standardize for Korean children by Oh et al(1997). Result: Total behavior problem score for children on treatment was greater than the score off treatment but there was no significant difference. Children on treatment reported higher levels of depression/anxiety, withdrawal, internalizing scores than children off treatment. Social competence score of children off treatment was greater than the score on treatment and the difference of school performance score of children between on and off treatment was not significant. The scores on the withdrawal, somatic complaints, social immaturity, internalizing scales in the cancer group including both on and off treatment was greater than normative findings in the general population. The scores on the school competence of children off treatment were lower than the norms for healthy children. Conclusion: Findings from this study support the importance of nursing interventions to facilitate the adjustment of children with cancer both on and off therapy.

  • A high attention has been paid on the running safety of Korean high-speed train, KTX. In running of KTX on bridge, the running unsafety problem issued from a resonance phenomenon of bridge, which was usually caused by the periodic wheel-loads of train. Therefore, many researches on this running safety of train on bridge have been conducted by domestic or foreign researchers. In this paper, for PSC box-girder bridge which is the representative high-speed railway bridge type, some numerical analyses on the dynamic characteristics of bridge with the non-periodic wheel-loads through vehicle size adjustment were performed. These numerical analyses shows the fact that the resonance phenomenon on bridge was mitigated through vehicle size adjustment. Additional numerical analyses on the vibration reduction of bridge in accordance with the location of size-adjusted vehicle were performed. From these results, it was represented that the adjustment of vehicle size has an effect on the running safety of train as well as the ride comfort.

  • Purpose: The purpose of this study was to identify sexual activities of males with spinal cord injury (SCI) and influential factors of sexual adjustment. Methods: A correlational survey was conducted among a total of 135 males with SCI. Results: After SCI, patients maintained low levels of sexual adjustment, and a main obstacle of sexual rehabilitation was decreased erectile function (65.2%). Sexual desires recovered in 84.4%, with 62.4% patients reporting more than once intercourse experiences. The erectile function of participants with normal, decreased or no erectile function were 13.0%, 62.6% and 24.4%, respectively. 8.1% of the participants reported no problem with ejaculation. Patients with incomplete SCI had better preserved erectile function than those with complete SCI (t=-4.627, p<.001). Patients with upper motor neuron injury had better preserved erectile function than those with lower motor neuron injury (t=2.446, p =.016). Sexual adjustment was relevant to age, job, degree of injury, post-injury period, sexual desire, intercourse experience, erection therapy, erectile function, and sexual health. Sexual adjustment was a factor of sexual health with a power of 24.2%. Conclusion: The main obstacle of sexual rehabilitation for males with SCI decreased erectile function. Erection and ejaculation are dependent on the severity and level of SCI. The major influence on sexual adjustment is sexual health.

  • A method for the free network adjustment is proposed, based on the application of generalized inverse matrix (g-inverse). If the network adjustment is executed according to the solution with parameters, especially when all coordinates are considered as parameters to keep unity strength, the matrix of normal equation will be singular. This paper discusses the problem of singular matrix and the analysis of accuracy between conventional method and the free network adjustment of trilateration. In case of the adjustment, the RMS errors of adjusted X, Y coordinates are increased to 35.6% in a polygon, central-point figure, and 50.5% in a quadrilateral. In the elements of error ellipse, the RMS errors are decreased by $\pm$24.5% (a) and $\pm$5.0 % (b) in the polygon, $\pm$42.6% (a) and $\pm$49.2% (b) in the quadrilateral. Introduction of free network adjustment, therefore, could be applied to improvement of relative accuracy in the horizontal positioning.

  • Purpose: The purpose of this study was to investigate the ecological factors influencing school adjustment of adolescents from low-income families. Methods: Secondary data analysis was performed using data of 1,321 low-income adolescents in 123 regions found on the Survey on Service Satisfaction with Community Child Care Center. Results: The results of multi-level analysis identified the factors influencing school adjustment of low-income adolescents as follows: individual-level factors were gender, grade in school, and emotional problem; an interpersonal-level factor was family structure; organizational-level factors were length of time attending center and satisfaction with the service of the center; community-level factors were region and perception of community. Conclusion: The results suggest that low-income adolescents' adjustment to school is influenced not only by individual factors but also by diverse environmental factors. Community factors suggest that more education support systems and leisure facilities for adolescents need to be built in small and medium cities. Strategies to enhance positive perception of community are also needed for this population. Further, it is necessary to develop multi-level interventions to improve the school adjustment of adolescents from vulnerable social groups.

  • This study examined the effects of interpersonal relationship harmony and stress coping on the college adjustment among nursing students. The participants were 231. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression. Adjustment to college life significantly correlated with interpersonal relationship harmony and stress coping style. Interpersonal relationship harmony was significantly different according to year, satisfaction with nursing as a major, and academic achievement. Multiple regression analysis showed that interpersonal relationship harmony and stress coping(problem-focused, emotion-focused, hopeful thought) explained 23% of variance in adjustment to college life. The study findings suggest that intervention intended to promote nursing students' adjustment to college life should focus on improving interpersonal relationship harmony and stress coping.

  • Visual discomfort is a common problem in three-dimensional videos. Among the methods to overcome visual discomfort presented in current research, disparity adjustment methods provide little guidance in determining the condition for disparity control. We propose a diaprity adjustment based on the characteristics of disparity distribution on visual comfort, where the visual comfort level is used as the adjustment paramter, in parallax barrier type auto-stereoscopic 3D display. In this paper, we use the horizontal image shift method for disparity adjustment to enhance visual comfort. The speeded-up robust feature is used to estimate the disparity distribution of 3D sequences, and the required amount for disparity control is chosen based on the pre-defined characteristics of disparity distribution on visual comfort. To evaluate the performance of the proposed method, we used a 3D equipment. Subjective tests were conducted at the fixed optimal viewing distance. The results show that comfortable videos were generated based on the proposed disparity adjustment method.

  • The purpose of this study was to improve the understanding of essential experiences of children of Alcoholism and explore their adjustment process from the children's perspectives. The specific research questions explored in this study were: 1. What was the central phenomenon that children of Alcoholism have experienced? 2. What was the adjustment process of the children of Alcoholism. The grounded theory was adopted in this study to address the research questions. Data was collected through in-depth interviews with eight young adult aged from 18-30 years olds who experienced their parent's Alcoholism. Grounded theory based data analyses resulted in 85 concepts, 30 sub-categories, and 16 categories. The 'causal conditions' influencing the central phenomenon was 'self denial' and 'being suppressed' is the central phenomenon for the children of Alcoholism. The core issue in the process of an adjustment of children from a Alcoholism family was 'accepting the parental Alcoholic problem and re-defining the self', The results of this study suggest that counseling interventions are suggested to improve children's well-being and facilitate their adjustment. Therefore this study has implication on building theory of intervention on the offsprings who have parents of Alcoholism.
