Background: Core stabilization exercises are widely used to improve trunk stability, balance, and functional movement by enhancing the activation and endurance of deep trunk muscles such as the transversus abdominis (TrA). However, evidence comparing the effects of sling-based unstable surface training and mat-based stable surface training remains limited. Objects: To investigate the effects of mat based core stabilization exercises and sling based unstable surface core stabilization exercises on transversus abdominis thickness and core endurance. Methods: Forty-six healthy adults were randomly assigned to a mat exercise group (MEG, n=23) or a mat with sling exercise group (MSEG, n=23). Both groups performed 30-minute core stabilization exercises twice per week for four weeks. TrA thickness was measured using ultrasonography (SONON 300L), and core endurance was evaluated using the Bourban test for the anterior muscle chain. Results: Both groups showed significant increases in transversus abdominis thickness (MEG: P<.05; MSEG: P<.00) and core endurance (P<.00) after the intervention. However, no statistically significant differences were found between the two groups in post-intervention TrA thickness or Bourban test. Conclusion: Both mat based and sling based core stabilization exercises effectively enhanced TrA thickness and core endurance in healthy adults.

Background: Previous systematic reviews and meta-analyses have suggested core stabilization exercise as a conservative treatment approach for scoliosis. Objectives: To investigate the effects of sling exercise and unilateral core exercise on the angle, balance ability, and muscle tone in individuals with scoliosis. Design: Randomized controlled trial. Methods: Twenty-one students in their twenties with mild scoliosis were recruited as participants and randomly assigned to one of three groups: a sling exercise group (n=7), a unilateral core exercise group (n=6), and a combined sling and unilateral core exercise group (n=6). Two participants dropped out during the study. Each group performed its designated exercise program individually, three times per week for five weeks. Measurements of scoliosis angle, balance, and muscle tone were taken before and after the intervention. Results: The sling exercise intervention significantly reduced the scoliosis angle (P<.05) and significantly increased muscle tone on the convex side (P<.05). In the combined sling and unilateral core exercise group, a significant improvement in static balance ability was observed (P<.05). Conclusion: Among the core stabilization exercises applied to scoliosis, sling exercise may be considered a potential intervention for mild scoliosis.

2019년 동남아시아 국가연합(ASEAN)이 채택한 ‘인도·태평양에 대한 아세안의 관점(AOIP)’은 새로운 질서를 제시하거나 새로운 협력 메커니즘 을 수립하는 등 기존 메커니즘을 획기적으로 대체한 것은 아니었다. 오히 려 기존의 협력 아젠다들을 종합하고 정리한 문서로 여겨진다. 그렇다면 아세안은 왜 이러한 지역 전략 문서를 채택했는가? 본 연구는 이 질문에 대답하기 위해 아세안 AOIP의 수립 배경과 이를 통한 아세안의 인태전략 해석에 초점을 맞춘다. 기존 연구는 아세안의 인태전략이 외부 환경과의 고려 가운데 내려진 전략적 선택의 결과물이라는 점을 종종 간과하고 있 다. 본 논문은 아세안의 전략적 선택 추론을 위해 아세안에게 크게 네 가 지 가능성이 있었음을 제시한다. 이를 뒷받침하기 위해 AOIP와 기타 협 력 이니셔티브 등의 내용을 분석하여 소개한다. 또한 구체적 근거 제시를 위해 AOIP에서 강조된 4가지 영역(해양협력, 연계성, UN SDGs, 기타 경 제협력 등)이 대화 상대국과의 협력 과정에서 어떻게 등장하는지 살펴본 다. 본 연구는 인태지역을 둘러싼 이해 당사국의 역동성을 아세안의 AOIP 수립을 통해 구체화했다는 연구 함의와 더불어 향후 이를 중심으로 한 AOIP의 발전 가능성을 탐구했다는 점에 연구 의의를 갖는다.

Indonesian women have emerged as global consumers, and various studies are needed to expand the global fashion market targeting their needs. In this study, a survey was conducted to determine the fashion design preferences of Indonesian Muslim women according to demographic characteristics and religious variables. In this study, Indonesian women aged from their teens to their 40s were surveyed by questionnaire during June 2020. This yielded 301 survey responses, which were analyzed using χ2-test, t-test, ANOVA, and Duncan's multiple range test using SPSS23. The results of the study are as follows: Analysis of the demographic characteristics of Indonesian Muslim women and the degree of acceptance of fashion trends according to religious variables showed significant differences according to age, monthly income, and the extent to which they wore a hijab. Analysis of the demographic characteristics of the women and the degree of acceptance of the fitted garment according to religious variables showed significant differences depending on their age, whether they were married, their monthly income, religious faithfulness, the extent to which they wore a hijab, and the degree of acceptance of Islamic discipline. After examining the difference in Muslim women’s preferred fashion images (according to demographic characteristics and religious variables), significant differences were identified according to their age, income, extent to which they wore a hijab, and the degree of Islamic discipline with regard to clothing.

In this study, the precise orbit determination (POD) software is developed for optical observation. To improve the performance of the estimation algorithm, a nonlinear batch filter, based on the unscented transform (UT) that overcomes the disadvantages of the least-squares (LS) batch filter, is utilized. The LS and UT batch filter algorithms are verified through numerical simulation analysis using artificial optical measurements. We use the real optical observation data of a low Earth orbit (LEO) satellite, Cryosat-2, observed from optical wide-field patrol network (OWL-Net), to verify the performance of the POD software developed. The effects of light travel time, annual aberration, and diurnal aberration are considered as error models to correct OWL-Net data. As a result of POD, measurement residual and estimated state vector of the LS batch filter converge to the local minimum when the initial orbit error is large or the initial covariance matrix is smaller than the initial error level. However, UT batch filter converges to the global minimum, irrespective of the initial orbit error and the initial covariance matrix.
