In this paper, we discussed automatic target tracking algorithms for diver detection sonar that observes penetration forces of coastal military installations and major infrastructures. First of all, we analyzed sea trial data in diver detection sonar and composed automatic target tracking algorithms based on track existence probability as track quality measure in clutter environment. In particular, these are presented track management algorithms which include track initiation, confirmation, termination, merging and target tracking algorithms which include single target tracking IPDAF (Integrated Probabilistic Data Association Filter) and multitarget tracking LMIPDAF (Linear Multi-target Integrated Probabilistic Data Association Filter). And we analyzed performances of automatic target tracking algorithms using sea trial data and monte carlo simulation data. 본 논문은 연안 군사시설 및 주요 기반시설에 대한 침투세력을 감시하는 수영자 탐지 소나에서의 자동 표적추적 알고리즘을 다루었다. 이를 위해 수영자 탐지 소나에서의 해상실험 데이터를 분석하였고, 클러터 환경에서 자동표적 추적을 위한 트랙평가수단으로서 트랙존재확률 기반의 알고리즘을 적용하여 시스템을 구성하였다. 특히 트랙초기화, 확정, 제거, 합병 등의 트랙관리 알고리즘과 단일표적추적 IPDAF(Integrated Probabilistic Data Association Filter), 다중표적추적 LMIPDAF(Linear Multi-target Integrated Probabilistic Data Association Filter) 등의 표적추적 알고리즘을 제시하였으며, 해상실험 데이터 및 몬테카를로 모의실험 데이터를 이용하여 성능을 분석하였다.

In this paper, we propose a method of TMA(Target Motion Analysis) performance improvement using target elevation tracking and fusion in conformal array sonar. One of the most important characteristics of conformal array sonar is to detect a target elevation by a vertical beam. It is possible to get a target range to maximize advantages of the proposed TMA technology using this characteristic. And the proposed techniques include target tracking, target fusion, calculation of target range by multipath as well as TMA. A simulation study demonstrates the outstanding performance of proposed techniques.

A fundamental characteristic of PMHT (Probabilistic Multi-Hypothesis Tracker) is that the number of targets and initial states of targets in the surveillance area must be a priori known. This requirement is impossible to fulfil in almost every realistic scenario. In the paper, we present two track initiation methods to solve the problem. The proposed track initiation methods are 2-point track initiation and Hough transform track initiation, and they are used to evaluate track initial states and weights for FTD (False Track Discrimination) of the PMHT algorithm. Also suggested as automatic target detection for tracking systems that combines track initiation for target detection with the PMHT algorithm for target tracking in a cluttered environment. A series of Monte-Carlo simulation runs is employed to evaluate the overall system performance with the two track initiation methods and the results are compared and analyzed.

To enhance tracking efficiency, a target-tracking filter with a resource management algorithm is required. One of the resource management algorithms chooses or evaluates the proper sampling time using cost functions which are related to the target tracking filter. We propose a resource management algorithm for bearing only tracking environments. Since the tracking performance depends on the system observability, the bearing-only tracking is one of challenging target-tracking fields. The proposed algorithm provides the adaptive sampling time using the variation rate of the error covariance matrix from the target-tracking filter. The simulation verifies the efficiency performance of the proposed algorithm.

Background : Smoking reduces the ability of the lungs to function. In particular, smoking reduces the vital capacity of the lungs, which is the amount of air the lungs can take in. This reduction in vital capacity has several important health effects. Purpose : The purpose of this study, therefore was to examine the effects of the respiratory muscle exercise on peak expiratory flow and respiratory muscle strength. Methods : For an experimental research design, it was employed 20 young healthy subjects and these subjects were assigned into two groups; a smoking group(n=10) and an non-smoking group(n=10). All groups were participated in respiratory muscle exercises twice a week for 5 weeks in same condition. For comparison between before and after for post treatment, it was analysed as paired t-test and ANCOVA. Results : The result of this study were as follows; In the case of smoking group, there were significant differences, from $427.77{\pm}76.61$ l/min to $526.66{\pm}58.52$ l/min of peak respiratory flow, from $94.33{\pm}22.07$ kg to $102.16{\pm}21.60$ kg of abdominal muscle strength between the before and the after of respiratory muscle strength exercises. In the case of nonsmoking group, there were significant differences, from $449.54{\pm}77.47$ l/min to $553.18{\pm}61.32$ l/min of peak respiratory flow, from $93.41{\pm}19.21$ kg to $101.58{\pm}18.92$ kg of abdominal muscle strength between the before and the after of respiratory muscle strength exercises. Conclusion : These results were suggested that the peak respiratory flow and muscle strength were improved after respiratory muscle strength exercises.
