Motor intentional disorders have been studied by visual examination methods such as cross-response task and Luria loop. To provide more analytical, quantitative information for motor intentional disorders, the present study developed a method which evaluates force control capabilities by the index finger. The assessment method analyzes the finger force control capabilities at four stages(initiation, development, maintenance, and termination) with NK Pinch-GripTM(force resolution= 0.098 N; temporal resolution=50Hz). By applying the assessment method, a patient(age=66) with callosal legion was compared with 6 healthy males(mean age=65.5, SD=2.8), showing significant but different decreases in force control capabilities depending on hand and response location. The assessment method would be of use to better understand various aspects of motor intentional disorders such as the effects of the disorders to the neurological network of the brain and severity assessment of the disorders.

The purpose of this article is to analyze the progress of North Korea's SLBM threat, and to assess the technological capacity and threat level of its SLBMs. Currently, North Korea has approximately 1000 ballistic missiles, such as the SCUD, Musudan, and Nodong, in stock. This article pays close attention to the background and strategical implication behind North Korea's obsession with developing SLBMs despite possessing sufficient means to launch provocations with its current arsenal of ground based ballistic missiles and conventional weapons. Based on the abovementioned analysis, this article will recommend possible response directions for the ROK Armed Forces to North Korea's SLBM threat. It is highly difficult to detect SLBMs due to its stealthy nature, as it is launched underwater after covert infiltration. North Korea's SLBM is considered a game changer in that even one SLBM can significantly change the strategic balance of North East Asia. North Korea's SLBM test launch in August has made a 500km flight, landing 80km inside the JADIZ (Japan Air Defense Identification Zone), and as such, it is assessed that North Korea already possesses underwater ejection and cold launch capabilities. The most realistic response to North Korea's imminent SLBM threat is bolstering anti-submarine capabilities. ROK Armed Forces need to upgrade its underwater kill-chain by modernizing and introducing new airborne anti-submarine assets and nuclear-powered submarines, among many options. Moreover, we should integrate SM-3 missiles with the Aegis Combat system that possess strong detection capabilities and flexibility, thereby establishing a sea-based Ballistic Missle Defense (BMD) system centered around the Aegis Combat System, as sea-based ballistic missile threats are best countered out in the seas. Finally, the capabilities gap that could arise as a result of budgetary concerns and timing of fielding new assets should be filled by establishing firm ROK-US-Japan combined defense posture.

Purpose: This study aimed to evaluate and assess the response capabilities and educational needs of 119 emergency medical technicians (EMTs) in chemical accidents. Methods: A self-reported questionnaire was completed by 167 119 EMTs between December 1st and December 31, 2023. The questionnaire comprised 8 questions on general characteristics, 2 on chemical accidents experienced by the participants, 29 on response capabilities, and 15 on educational needs. Data analysis was performed using t-tests, analysis of variance, Duncan's test for post-hoc analysis, and Pearson's correlation coefficient, using SPSS 27.0. Results: The participants scored 2.69 points on response capacity to chemical accidents. The EMT-Paramedics scored high in 'patient triage,' 'patient treatment,' 'patient transport,' and 'collaborative support' (F=3.924, p=.010; F=5.843, p=.001; F=3.698, p=.013; F=5.272, p=.002), followed by educational experience (t=-4.962, p<.001; t=-2.685, p=.008; t=-3.455, p=.001; t=-3.593, p<.001; t=-3.034, p=.003). The participants scored 4.19 points on educational needs, with high scores for 'patients treatment and transport' (4.280.93). The scores for 'patient triage competency', and 'patient triage' (r=.169, p=.024) correlated positively. Furthermore, the scores for 'patient treatment competency' and all sub-factors of educational needs (r=.185, p=.013; r=.215, p=.004; r=.199, p=.008; r=.190, p=.011; r=.197, p=.008) correlated positively. Conclusion: To strengthen the response capabilities of 119 EMTs, it is imperative to develop an educational program that focuses on first-aid responses.

This paper addresses the problem of the modeling and vibration control of tapered rotating blade modeled as thin-walled beams and incorporating damping capabilities. The blade model incorporates non-classical features such as anisotropy, transverse shear, secondary warping and includes the centrifugal and Coriolis force fields. For the rotating blade system, a thorough validation and assessment. of a number of non-classical features including the taper characteristics is accomplished. The damping capabilities are provided by a system of piezoactuators bonded or embedded into the structure and spread over the entire span of the beam. Based on the converse piezoelectric effect, the piezoactuators produce a localized strain field in response to a voltage and consequently, a change of the dynamic response characteristics is induced. A velocity feedback control law relating the piezoelectrically induced transversal bending moment at the beam tip with the appropriately selected kinematical response quantity is used and thebeneficial effects upon the closed-loop dynamic characteristics of the blade are highlighted.

The stochastic response surface method (SRSM) and the response surface method (RSM) are often used for structural reliability analysis, especially for reliability problems with implicit performance functions. This paper aims to compare these two methods in terms of fitting the performance function, accuracy and efficiency in estimating probability of failure as well as statistical moments of system output response. The computational procedures of two response surface methods are briefly introduced first. Then their capabilities are demonstrated and compared in detail through two examples. The results indicate that the probability of failure mainly reflects the accuracy of the response surface function (RSF) fitting the performance function in the vicinity of the design point, while the statistical moments of system output response reflect the accuracy of the RSF fitting the performance function in the entire space. In addition, the performance function can be well fitted by the SRSM with an optimal order polynomial chaos expansion both in the entire physical and in the independent standard normal spaces. However, it can be only well fitted by the RSM in the vicinity of the design point. For reliability problems involving random variables with approximate normal distributions, such as normal, lognormal, and Gumbel Max distributions, both the probability of failure and statistical moments of system output response can be accurately estimated by the SRSM, whereas the RSM can only produce the probability of failure with a reasonable accuracy.

해사안전을 위한 비상대응훈련 및 해기교육기관의 안전교육은 정해진 시나리오와 교육내용을 기반으로 실시되기 때문에, 다양한 상황에 따른 인적오류 감소와 대응에는 한계가 있다. 이에 대한 개선 필요성이 요구되고 있으나, 기존 교육훈련에 대한 평가와 상황의 다양성 확보를 통한 대응능력 향상을 위한 방안은 부재하다. 본 연구는 비상대응훈련 개선을 위해 상황 다변성을 모델링할 수 있는 이론적 절차 분석기법을 제안한다. 선원과 시스템의 유기적 관계에 기반한 인적 및 시스템 이론적 절차 분석 모델(HSTPA)을 정의하고, 각 구성요소들이 발생시킬 수 있는 오류를 분석, 수직적 보고체계와 대응이 요구되는 화재대응 훈련 시나리오에 이를 적용하여 기존 훈련의 한계점을 식별하였다. 제안된 HSTPA 모델을 적용한 훈련 시나리오 고려요소의 세분화 및 점검은 비상대응훈련 및 교육에 있어 다양하고 현실적인 시나리오 생성과 피훈련자들의 상황판단 이해력 및 대응능력 향상에 도움이 될 것으로 판단된다.
