Objective : The aims of this study was to investigate the effects of modified constraint induced movement therapy(CIMT) on upper extremities function of children with hemiplegic cerebral palsy. Methods : The participants of this study are 4 children with hemiplegic cerebral palsy aged between 8 to 11 years old. During the modified CIMT period, the unaffected hand of the subjects was restrained by a hand splint for 8 weeks, five days per week, five hours a day. And the affected upper extremity was strongly trained by performing functional tasks, which were individually structured use of the affected arm. Measurements used to assess hand function are Jebsen Hand Function Test, and 3D Motion Analysis. The Jebsen Hand Function Test was performed repeatedly every two weeks. The 3D Motion Analysis was performed before and after the 8 weeks of modified constraint induced movement therapy. Results : After the modified CIMT, there was a significant improvement in completed time for the 6 tasks of Jebsen Hand Function Test(p<.05). 3D Motion Analysis was that the finger tapping and the hand tapping has been significantly decreased (p<.05), and the pronation-supination movement has been significantly increased as well(p<.05). Conclusion : In the results of this study, it is evidenced that modified CIMT is effective treatment for upper extremities function of children with hemiplegic cerebral palsy. For future research, it is recommended to examine various periods and protocol of modified CIMT including impact of long periods application.

The absolute value management method is widely used in the most of the earth retaining construction, which evaluates the safety by comparing measurement result and management criteria. Therefore, the management criteria is the standard to evaluate the safety of the site, and in other words, the criteria is a direct factor of the evaluation. That means that the safety of the site can not be acquired if the management criteria is not proper, even though the measurement system is perfectly set. However, many of field technicians do not have rely on the current management criteria, and they even recognize the necessity of the revision. Therefore, in this study, the necessity of the revision was studied. Also, the optimum criteria selection and the application were performed based on the test results of earth retaining deflection and probabilistic theory. The absolute value management method was used for this study. The details are tabulated.

The selection of appropriate ground motions and reasonable modification are becoming increasingly critical in reliable prediction on seismic performance of structures. A widely used amplitude scaling approach is not sufficient for robust structural evaluation considering a site specific seismic hazard because only one spectral value is matched to the design spectrum typically at the structural fundamental period. Hence alternative approaches for ground motion selection and modifications have been suggested. However, there is no means to evaluate such methodologies yet. In this study, it is focused to describe the main questions resided in the amplitude scaling approach and to propose a regression model for structural damage as point of comparison. Spectrum compatible approach whose resulting spectrum matches the design spectrum at the entire range of the structural period is considered as alternative to be compared to the amplitude scaling approach. The design spectrum is generated according to ASCE7-05.

In this paper, we applied modified slope rotatability introduced by Victorbabu (2005) to the central composite design of second type, and studied related content. We suggested methods of constructing central composite designs of second type which have modified slope rotatability. Especially, this property has the advantage that it can be used to sequential experiments, because we can obtain central composite designs of second type which have modified slope rotatability by adding experimental points without changing the axial values to central composite designs of second type having Box-Hunter rotatability. We explained central composite designs of second type which have modified slope rotatability by using two examples.

전체적인 조선 생산일정계획을 수립하기 위해서 계층적 구조를 채택하였다. 이 구조에 의하면 도크의 상위 일정계획 생성기는 탑재 일정계획을 생성하고, 조립공정의 하위 일정계획 생성기는 상위 일정계획 생성기가 요구하는 범위 내에서 각각 세부적인 조립 일정계획을 세우게 된다. 그런데 하위 일정계획 생성기가 아무리 노력하여도 상위 일정계획 생성기로부터의 제약조건을 만족시킬 수 없는 상황이 발생하면, 일정계획 수정기에 통보하여 초기 탑재 일정계획을 수정해야 한다. 하위 일정계획 생성기로부터의 조정요청을 반영하기 위해서 부분 수정을 통해 충격을 최소화시키는 일련의 휴리스틱으로 구성된 알고리즘을 제시하였다. 각각의 휴리스틱은 여유시간 제거, 버퍼 제거, 작업시간 축소, 다단계 여유시간 제거, 과부하 자원 공유블럭 조정, 자원 제약조건 완화 등이고, 흡수되지 않은 일부의 충격은 주변으로 전파된다. 이와같은 방법론을 대우조선의 상황에 적용하여, 조선일정계획 수정 시스템인 DAS-REACT를 개발하였다.

In this paper, we propose three new text-independent speaker identification methods. At first, to exclude the frames not having enough features of speaker's vocal from calculation of the maximum likelihood, we propose the FS(Frame Selection) method. This approach selects the important frames by evaluating the difference between the biggest likelihood and the second in each frame, and uses only the frames in calculating the score of likelihood. Our secondly proposed, called the Hybrid, is a combined version of the FS and WMR(Weighting Model Rank). This method determines the claimed speaker using exponential function weights, instead of likelihood itself, only on the selected frames obtained from the FS method. The last proposed, called MWMR (Modified WMR), considers both original likelihood itself and its relative position, when the claimed speaker is determined. It is different from the WMR that take into account only the relative position of likelihood. Through the experiments of the speaker identification, we show that the all the proposed have higher identification rates than the ML. In addition, the Hybrid and MWMR have higher identification rate about 2% and about 3% than WMR, respectively.

In vitro culture has provided new information on the mechanisms involved in fertilization how sperm and oocyte fuse together. At the same time, results obtained in vitro have led to new questions. Techniques for In vitro maturation of porcine oocytes have progressed such that the problem of the low rate of pronucleus formation with in vitro matured oocytes after in vitro fertilization has been nearly improved. On the other hand, porcine spermatozoa have been shown to be capacitated if the fertilization medium contains caffeine and Ca$^2+$, but the incidence of polyspermy in IVM-IVF oocytes is still high. To prevent polyspermy, co-culture with oviductal cells, sperm preincubation with porcine follicular fluid or control of sperm concentration, have been examined with significant effects but still remarkably high rates of polyspermy. The under standing of these influences is a prerequisite to enhancing in vitro production of porcine em bryos.

Solar radiation data are important data that can be used as basic research data in diverse areas. In particular, solar radiation data are essential for diverse studies that have been recently conducted in South Korea including those for new and renewable energy resource map making and crop yield forecasting. So purpose of this study is modification of Heliosat-II method to estimate solar irradiance in Korea by using COMS-MI imagery. For this purpose, in this study, errors appearing in ground albedo images were corrected through linear transformation. And method of producing background albedo map which is used in Heliosat-II method is modified to get more finely tuned one. Through the study, ground albedo correction could be successfully performed and background albedo maps could be successfully derived. Lastly, In this study, solar irradiance was estimated by using modified Heliostat-II method. And it was compared with actually measured values to verify the accuracy of the methods. Accuracy of estimated solar irradiance was 30.8% RMSE(%). And this accuracy level means that solar irradiance was estimated on 10% higher level than previous Heliosat-II method.

Objective: The aim of this study was to compare the fertilization and cleavage rates of human in vitro matured oocytes after fertilized by conventional in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). Methods: A total of 135 GV stage oocytes were obtained from 59 women who received ovarian stimulation and IVF during Jan 2007 to Oct 2008. Ovarian hyperstimulation was performed using hMG or recombinant FSH with GnRH antagonist and then ovulation triggered by recombinant hCG. The immature oocytes obtained from stimulation cycles were cultured in IVM medium up to 48 hrs; commercial medium supplemented with rFSH 75 mIU/mL, rhCG 0.5 IU/mL and rEGF 10 ng/mL. The in vitro matured oocytes were fertilized by conventional IVF (41 GV oocytes) or ICSI method (94 GV oocytes). Results: Maturation rate were 51.2% and 59.6% in conventional IVF group and ICSI group, respectively. There was no significant difference in fertilization rates between two groups; 71.4% and 80.4%, respectively. The cleavage rate was also similar in two groups. Conclusion: The presented data suggest that conventional IVF has comparable fertilization and cleavage potential compared with ICSI as the insemination method of immature human oocytes obtained from stimulated cycle.
