The subject were consist of 8 males and 8 females in Taekwondo Athletes, The result of this study by analysis of variance of raw data from repetition measurement both male and female at the pre and post competition were as follows.1. There was no significant difference of HR between male and female in competition, but between 1R and 2R and between 1R and 3 were significantly different. The highest HR of each round was 180∼189bpm, 90∼95% of HRmax.2. There was no significant difference of blood lactate between male and female, but lactate was significantly increased as times went by, and especially at the post immediately 3R was increased three times at rest.3. There was a significant difference of systolic pressure between male and female at each round. Systolic pressure of male athletes was 13∼22mmHg higher than female athletes after each round, and MV˙O_2 of male athletes was 1∼4.6mmHg·bpm^-3 higher than female, that was increased a few times at rest. As a result HR and blood lactate were no significantly different between male and female athletes in Taekwondo competition. But, blood pressure and MV˙O₂ in male athletes were higher than female. In conclusion, the results suggest that it is necessary to figure out the best way to develop athletic performance by applying individual exercise intensity or different program during the Taekwondo training.

본 연구에서는 현재 일반적인 스마트 팩토리에서 데이터 전송에 사용하는 중앙 집중형 시스템에서 발생하는 데이터를 중앙의 센터까지 전송, 처리할 때 발셍하는 전송 지연 등의 문제 해결을 위하여 필요한 곳에 연산과 저장 장치를 도입하는 분산 컴퓨팅 패러다임 (Distributed Computing Paradigm)인 온-디바이스 (On-Device) 기반 에지 컴퓨팅 (Edge Computing) 기술과 빅데이터 분석 기술 및 활용 방법의 연구를 통하여 설비 고장 등을 예지하여 가동율을 높일 수 있는 산업현장의 설비관리에 활용되는 솔루션을 제안한다. 그러나 에지 컴퓨팅 기반의 기술이 실제 적용되더라도 네트워크 에지에서 장치의 증가는 많은 양의 데이터가 데이터 센터로 전달되어 네트워크 대역이 한계치에 이르게 되어 네트워크 기술의 향상에도 데이터 센터는 수많은 응용에서 중요한 요건이 되는 수용 가능한 전송 속도와 응답 시간을 보장하지 못하게 된다. 이와 같은 요구조건을 수용할 수 있는 일체형 하드웨어 기술과 공장관리 및 제어 기술을 적용한 설비보존 및 스마트 팩토리 산업 분야에 적용할 수 있는 연구를 통하여 생산성 증대를 지원할 수 있는 지능적 설비관리를 지원하도록 하여 추후 빅데이터에 적합한 딥러닝을 적용할 수 있는 인공지능 기반 설비 예지 보전 분석 도구로 발전할 수 있는 기반을 제공한다. In this paper we propose an uses on-device-based edge computing technology and big data analysis methods through the use of on-device-based edge computing technology and analysis of big data, which are distributed computing paradigms that introduce computations and storage devices where necessary to solve problems such as transmission delays that occur when data is transmitted to central centers and processed in current general smart factories. However, even if edge computing-based technology is applied in practice, the increase in devices on the network edge will result in large amounts of data being transferred to the data center, resulting in the network band reaching its limits, which, despite the improvement of network technology, does not guarantee acceptable transfer speeds and response times, which are critical requirements for many applications. It provides the basis for developing into an AI-based facility prediction conservation analysis tool that can apply deep learning suitable for big data in the future by supporting intelligent facility management that can support productivity growth through research that can be applied to the field of facility preservation and smart factory industry with integrated hardware technology that can accommodate these requirements and factory management and control technology.

The purpose of this study was to investigate the effect of 12weeks of aerobic training with different exercise intensity on blood lymphocyte number. Healthy college-aged males(22.53±1.91yr) were participated in the maximal exercise test before(N=32) and after(N=30) 12weeks of aerobic training. The subjects were divided into two groups; control groups(N=8), training group(N=24). Then training group was divided into three subgroups; 50%HRR(low, N=8), 70%HRR(middle, N=8), 85%HRR(high, N=8). Two persons were eliminated during the training. To investigate the effect of aerobic training on blood lymphocyte number were measured at rest, immediately after exercise and 60min recovery. Maximal exercise testing was used the Bruce protocol on the treadmill. VO_(2max) were measured by maximal exercise testing, exercise intensity was determined for aerobic training treatment a basis of this measured values. speed and grade at 50%, 70%, 85%VO_(2max) and 50%, 70%, 85% of %HRR gained pre test were produced and applied. The programs of exercise groups were aerobic treadmill exercise for 12weeks. Three groups performed almost 40min, 30min, 20min per day(3days/week) by 300㎉ respectively. Venous blood were drawn at the forearm antecubital vein at rest, immediately after exercise and 60min recovery. First, there was no significant differences of T-cell among four groups in number, but there was significant differences before and after training and sampling time in number(P<.01, .001). Second, there was no significant differences of B-cell among four groups in number, but there was significant differences before and after training and sampling time in and number(P<.01, .001). Also, there was no interaction effects. Third, there was no significant differences of NK-cell among four groups in number, but there was only significant differences before and after training in number(P<.01). there was significant differences of sampling time in number(P<.001). There was no interaction effects before and after training and sampling time in number. Forth, there was no significant differences of Th(CD4+)/Ts(CD8+) ratio among four groups, but there was significant differences before and after training and sampling time(P<.01, .001). Also, there was significant differences interaction effects among groups, before and after training, and sampling time(P<.05). Results indicate that the exercise-induced lymphocyte subset reduction is transient and suggest that it is not dependent upon training intensity in the case of college-aged male, but aerobic training of various intensity is associated with sustained alterations in immune function, both at rest and when exercising.
