The purpose of this study was to make a pants pattern suitable for women 70 to 85 years of age, then analyze that- pattern's shape, size, appearance, fit, allowance and air gap. Participants made the pattern using 3D simulation program DC Suite version 5.1. The results suggest a design method suitable for the lower-body shapes of elderly women. In external appearance, the A-type earned the highest evaluation in all items except the allowance of the back waist and back hip. The L type earned the highest evaluation in the allowance of back waist and hips. The A-type's, back waist appeared set at an angle that did not match the body shape of an old-old aged woman in the center-back-line setting. Therefore, the pattern method of A-type combined with L-type's method of center back, produces an excellent pants pattern. Evaluation of the air gaps among patterns revealed that; the A-type showed the largest air gap in waist and hip circumference and the smallest air gap in thigh circumference. The waists, abdomen, and hip circumferences of older women often become larger while their legs become slimmer. This study accounted for those factors in determining a pattern suitable for the lower-body shape of old-old aged women. However, participants only analyzed four patterns and compared them with women 70 to 85, years of age. Therefore, it is necessary to develop industrial patterns applicable to a wide age group.

데이터 스트림에 대한 기존의 패턴 분석 알고리즘은 대부분 속도 향상과 효율적인 메모리 사용에 대하여 연구되어 왔다. 그러나 기존의 연구들은 새로운 패턴을 가진 데이터 스트림이 입력되었을 경우, 이 전에 분석된 패턴을 버리고 다시 패턴을 분석하여야 한다. 이러한 방법은 데이터의 실시간적인 패턴 분석을 필요로 하는 실제 환경에서는 많은 속도와 계산 비용이 소모된다. 본 논문에서는 끊임없이 입력되는 데이터 스트림의 패턴을 실시간으로 분석하는 방법을 제안한다. 이 것은 먼저 빠르게 패턴을 분석하고 그 다음부터는 이전에 분석된 패턴을 효율적으로 갱신하여 실시간적인 패턴을 얻어내는 방법이다. 데이터 스트림이 입력되면 시간 기반 윈도우로 나누어 여러 개의 순차들을 생성한다. 그리고 생성된 순차들의 정보는 해시 테이블에 입력되어 정해진 개수의 순차가 해시 테이블에 채워질 때마다 해시 테이블에서 패턴을 분석해 낸다. 이렇게 분석된 패턴은 패턴 트리를 형성하게 되고, 이 후에 새로 분석된 패턴들은 이 패턴 트리 안의 패턴 별로 갱신하여 현재 패턴을 유지하게 된다. 새로운 패턴 추가를 위해 패턴을 분석할 때 이전에 이미 발견된 패턴이 Suffix로 나올 수 있다. 그러면 패턴 트리에서 이 전 패턴으로의 포인터를 생성하여 중복되는 패턴 분석으로 인한 계산 시간의 낭비를 방지한다. 그리고 FIFO방법을 사용하여 오랫동안 입력이 안 된 패턴을 손쉽게 제거한다. 패턴이 조금씩 바뀌는 데이터 스트림 환경에서 RSP-DS가 기존의 알고리즘보다 우수하다는 것을 성능 평가를 통하여 증명하였다. 또한 패턴 분석을 수행할 데이터 순차의 개수와 자주 등장하는 데이터를 판별하는 기준을 조절하여 성능의 변화를 살펴보았다.

In this study, a spiking cortical model (SCM) based n-g discrimination method is proposed. The SCM-based algorithm is compared with three other methods, namely: (i) the pulse-coupled neural network (PCNN), (ii) the charge comparison, and (iii) the zero-crossing. The objective evaluation criteria used for the comparison are the FoM-value and the time consumption of discrimination. Experimental results demonstrated that our proposed method outperforms the other methods significantly with the highest FoM-value. Specifically, the proposed method exhibits a 34.81% improvement compared with the PCNN, a 50.29% improvement compared with the charge comparison, and a 110.02% improvement compared with the zero-crossing. Additionally, the proposed method features the second-fastest discrimination time, where it is 75.67% faster than the PCNN, 70.65% faster than the charge comparison and 38.4% slower than the zero-crossing. Our study also discusses the role and change pattern of each parameter of the SCM to guide the selection process. It concludes that the SCM's outstanding ability to recognize the dynamic information in the pulse signal, improved accuracy when compared to the PCNN, and better computational complexity enables the SCM to exhibit excellent n-γ discrimination performance while consuming less time.

Purpose: Human body have biological rhythmic pattern in a day, which is affected by internal and external environmental factors. We investigated whether respiratory function was fluctuated according to the influence of time-of-day (around at 9 am, 1 pm, and 6 pm) in health subjects, using pulmonary function test (PFT). Methods: Eighteen healthy volunteers (8 men, mean ages; $22.4{\pm}1.6$, mean heights; $166.61{\pm}9.60$, mean weight; $59.3{\pm}10.3$) were recruited. Pulmonary function test (PFT) was measured at three time points in day, around 9 am, 1 pm, and 6 pm in calm research room with condition of under 55dB noise level, using a spirometer (Vmax 229, SensorMecis, USA). Forced vital capacity (FVC), forced expiratory volume at one second (FEV1), FVC/FEV1, and peak expiratory flow (PEF) were acquired. Results: In comparison of raw value of PFT among three time points, subjects showed generally better respiratory function at 9 am, than at other points, although no significance was found. In comparison of distribution of ranking for respiratory function in each individual, only PEF showed significant difference. In general, distributional ratio of subjects who showed best performance of respiratory function in a day was high. Conclusion: These findings showed that circadian rhythm by diurnal pattern was not detected on respiratory function throughout all day. But, best performance on respiratory function was observed mostly in the morning, although statistical significance did not exist.

Purpose: The purpose of this study was to understand the effect of aquatic exercise on balance and depression of stroke patients. Methods: For 12 participants with stroke, six members of the experimental group and six members of the control group were randomly selected and arranged. Proprioceptive Neuromuscular Facilitation (PNF) lower extremity aquatic pattern exercise was applied to the experimental group. On the other hand, participants in the control group performed PNF lower extremity pattern exercise on the ground. Both exercises were performed 30 minutes per day, five times per week, for a period of six weeks. Balance was assessed using the Berg Balance Scale (BBS) and Timed Up to Go test (TUG). Depression was measured using the Center for Epidemiologic Studies depression scale (CES-D). Results: As a result of comparison within groups, the experimental group showed significant difference for balance and depression after the experiment (p<0.05). In comparison between the two groups, the experimental group in which aquatic exercise was applied showed more significant change in balance and depression than the control group (p<0.05). Conclusion: According to the results of this study, aquatic exercise was proven to enhance the balance and decrease the depression of stroke patients.
