  • In this paper, the dynamics on a transcendental entire semigroup G is investigated. We show the possible values of any limit function of G in strictly wandering domains and Fatou components, respectively. Moreover, if G is of class $\mathfrak{B}$, for any $z$ in a Fatou domain, there does not exist a sequence $\{g_k\}$ of G such that $g_k(z){\rightarrow}{\infty}$ as $k{\rightarrow}{\infty}$.

  • Gravitationally bound objects in the universe have been a main target of astronomers for long. However, some objects in the universe may want to be free, as we do. Recently we are witnessing the existence of some globular clusters wandering in the nearby universe. The nature and origin of these wandering globular clusters are not yet known. With the advent of giant telescopes they will be an excellent tool for various fields of research including first stars, star clusters, galaxies, and galaxy clusters.

  • Wandering spleen is a rare condition characterized by migration of the spleen from its normal position due to laxity or absence of the supporting splenic ligaments. Ultrasonography shows the absence of the spleen in left upper quadrant (LUQ) and the presentation in the lower abdomen of a homognous mass whose sonographic appearance is consistent with that of a spleen. Contrast-enhanced CT reveals the absence of the spleen in LUQ, a soft tissue mass resembling spleen in the lower abdomen, and the splenic pedicle of whirled appearance. We present a case of wandering spleen, which could be diagnosed with US and CT by the ectopic location of spleen and the whirling pattern of splenic pedicle.

  • Torsion of the wandering spleen is a rare condition especially in children. Unfortunately, splenectomy was the advocated treatment of choice for wandering spleen in many children up to 1985 in spite of the well-known possibility of overwhelming postsplenectomy sepsis. Because of the conclusive evidence of the vital function of the spleen in infection, indication of splenectomy have been revised and more attention has been paid to preserving the spleen where possible. We are presented a girl with splenic torsion, seen as a migratory abdominal mass and intermittent vague abdominal pain. Splenopexy by fixation of the spleen to the diaphragm and posterolateral peritoneum and the use of Avitene in the splenic bed was successfully performed. Complete fixation of the spleen was confirmed by ultrasound a year after this procedure was carried out. The clinical presentation, etiology, diagnostic procedures and management are discussed also.

  • The research was conducted to investigate the characteristics of lateral wheel path distributions (wandering) in different traffic lanes. The Wandering may affect pavement life and various distress types. To achieve results presented that the normal distribution curve with symmetry was observed in the 3-lane roads. In the case of the 3-lane road (on one direction), 50-60cm, 65-85cm, and 80-95cm for the 1st, 2nd, and 3rd lanes, respectively. In addition, the 1st lane vehicles tended to pass on the right side to avoid th opposite side vehicles, while the outside lane vehicles tended to pass on the left side to avoid the walkway.

  • Objective : The purpose of this study was to effects of the Participation in physical group occupational therapy on cognitive function, neuropsychiatric, social behavior in elderly with wandering dementia. Methods : Thirteen elderly with wandering dementia who live in nursing home in this study. Assessment tools were made by using Cognitive function scale(CFS), Algase Wandering Scale-V2(AWS-2), Neuropsychiatric Inventory-Questionaire(NPI-Q), social-behavioral function measure(SBFM). physical group occupational therapy performed for forty minute, once a week for 9weeks. the assessment tools were made twice: before, after the intervention. Results : Significant differences between pre-treatment and post-treatment were found in the AWS(p<0.05) score and SBFM(p<0.05) score, NPI-Q behabioral and psychological level(p<0.05) score. The cognitive function and neuropsychiatric number showed improvement. but score was not significantly(p>0.05) difference after physical group occupational therapy Conclusion : The findings suggest that the physical group occupational therapy used in this study may be helpful and effectiveness in elderly with wandering dementia, further studies with more subjects and longer treatment period, including will be performed to justify these findings.

  • This paper studies a method to minimize the baseline wandering that make hard to extract R-wave in ECG. This method uses a difference signal between ECG and ascending slope tracing waves to minimize the baseline wandering. When the slope of ECG signal maintains the value or falls, the ascending slope tracing wave follows ECG signal directly, and this wave holds that value of ECG signal when the slope begins to rises in a certain time(=hold time). After this hold time, this wave traces ECG signal again. This method has been applied to MIT/BIH database to verify its efficacy and validity in practical applications.

  • Until now, the level design for games has played a very important role in the process of developing games since it has been mapped out and applied so the game players have fun to certain level in playing games. So as game becomes more complex the number of game designers also grow and to make diverse levels, work force and working hours also should grow larger. In this treatise, it suggest a way where level's structure is changing dynamically so with only one level you can experience diverse levels by introducing wandering agent to the level structure. Also, I am trying to show the possibility of balance between the players by wandering agent.

  • Purpose: This study was done to identify differences in the life transition process of parents caring for children with autism according to parents' socio-demographic characteristics. Methods: Participants were 194 parents caring for children with autism. Data were collected from December 2013 to February 2014 through self-report questionnaires, and analyzed using descriptive statistics, t-test, ANOVA with SPSS/WIN 20.0. Results: Mean scores for despairing or accepting phases were higher than those for denying or wandering phases in the life transition process. According to parents' gender, educational level, and job, there were some significant differences in the denying and wandering phases. Differences in denying phase by education (p=.033), job (p=.004) were significant. Respondents with higher educational level, and having a job showed a lower level of denying than other respondents. Wandering phase differed significantly by gender (p=.009) and job (p=.001). Mothers and those who did not have a job showed a higher level of wandering than fathers and those who had a job. However, there was no difference in the despairing or accepting phases. Conclusion: The life transition phase of parents with autistic children needs to be assessed to provide differentiated and intensive support program and help them move to the accepting phase.

  • This paper describes a design of a Wavelet Adaptive Filter(WAF) for the removal of the baseline wandering and the minimization of the signal distortion using by wavelet transform and adaptive filter in the ECG signal. WAF consists of two parts. The first part is wavelet transform that decomposes the ECG signal into seven frequency bands using Vaidyanathan and Hoang wavelet. The second part is adaptive filter that uses the signal of seventh low frequency band among the wavelet transformed signals as primary input and a unit impulse sequence as reference input. For the evaluation of the performance of WAF, we used several baseline wandering elimination filters such as commerical standard filter with cutoff frequency of 0.5Hz and general adaptive filter. We made use of MIT/BIH database and real patient data for the evaluation. In conclusion, WAF showed a lower ST segement distortion than standard filter and adaptive filter and has a higher eliminated noise power than standard filter and adaptive filter.
