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.

목적 : 본 연구는 배회가 있는 치매 노인에게 신체 그룹 작업치료 참여가 인지기능, 심리행동증상 및 사회적 행동기능에 어떠한 영향을 미치는지 알아보고자 하였다. 연구방법 : 본 연구는 대전 ${\bigcirc}{\bigcirc}$요양원에 거주하고 있는 노인 중 고도의 치매(MMSE-K 9점 이하)를 가지고 있는 노인 13명을 대상으로, 2010년 7월부터 2010년 9월까지 주 1회 총 9회 실시하였다. 평가도구는 배회유형과 정도를 알아보기 위해 Algase Wandering Scale-V2를 사용하였고, 인지기능을 알아보기 위해서 인지기능 척도를 사용하였고, 심리정신행동을 알아보기 위해서 Neuropsychiatric Inventory-Questionnaire (NPI-Q)를 사용하였으며, 사회행동기능을 알아보기 위해 사회행동 척도를 사용하였다. 결과 : 대응표본 t-test를 이용하여 신체그룹 작업치료를 시행하기 전과 후를 살펴본 결과 인지도 기능손상정도와 심리행동증상은 감소되었으나, 유의한 결과(p>0.05)를 얻지는 못하였고, 사회적 행동기능, 심리행동증상의 심각정도, 배회의 정도는 유의하게 감소(p<0.05)된 것을 보여주었다. 결론 : 신체 그룹 작업치료를 한 결과 고도의 치매노인도 향상되었으며, 특히 사회적 행동기능, 심리행동증상의 정도, 배회의 정도가 향상되었음을 볼 수 있었다. 치매를 가지고 있는 노인에게도 꾸준한 치료가 필요하며, 앞으로 충분한 대상자와 대조군 그리고 치매노인의 다양한 변수를 고려한 지속적인 프로그램 개발이 필요하다.

본 논문에서는 심전도(ECG)에서 R-파의 추출을 어렵게 하는 기저선 변동의 최소화 방법을 연구하였다. 이 방법에서는 기저선의 변동을 최소화하기 위하여 심전도와 상승 기울기 추적파의 차신호를 이용하였다. 여기서 상승 기울기 추적파는 심전도 신호에서 기울기가 하강할 때는 그대로 심전도 신호를 추적하고 기울기가 상승할 때는 그 시작시간의 심전도 신호를 기준값으로 일정시간 유지시켜 준 후 다시 원신호를 추적하는 파형이다. 구현된 방법의 효용성을 검증하기 위하여 MIT/BIH 데이터 베이스의 심전도에 적용하여 그 실효성을 확인하였다.

현재 게임 레벨 디자인은 게임 유저로 하여금 게임에서 일정수준의 재미를 느낄 수 있게 게 임을 구상하고 적용하는 것으로 게임개발과정에서 중요한 역할을 해왔다. 이러한 레벨 디자인은 레벨 디자이너에 의해 설계되어 왔으며, 대부분의 게임 개발팀에서는 한 레벨 디자이너가 한 레벨씩 맡아서 설계하고 있다. 따라서 게임이 복잡해질수록 레벨 디자이너의 숫자는 늘어나고, 다양한 레벨을 만들기 위해 들어가는 인력과 작업시간은 늘어나야 한다. 본 논문에서는 레벨 구조에 배회 에이전트를 도입하여 하나의 레벨만으로도 다양한 레벨들의 효과를 경험해 볼 수 있도록 레벨 구조가 동적으로 변환되는 방법을 제안한다. 또한 배회 에이전트에 의해서 사용자들 간의 밸런스 조절도 가능함을 보이고자 한다.

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.
