수영운동과 식이섭취제한으로 유도되는 체내 글리코겐의 변화가 혈액 및 조직 세포내 IL-6와 관련 신호전달 인자에 미치는 영향
안경준 ( Kyung-Jun An ),허성훈 ( Sung-hoon Hur ),이종삼 ( Jong-Sam Lee ),안나영 ( Na-Young Ahn ) 한국체육대학교 체육과학연구소 2021 스포츠사이언스 Vol.39 No.1
본 연구는 수영운동과 식이섭취제한에 의해 유도되는 근육 조직 내 글리코겐의 변화가 혈액과 근육 조직 세포내 IL-6(interleukin-6)의발현과 긴밀한 연관을 맺고 있는 세포 내 신호전달체계의 변화를 연구하고자 하였다. 실험동물을 통제군(n=12)과 단식군(n=12) 및 운동군(n=12)으로 임의배정하였고, 혈액 및 조직 적출을 위해서 단식군의 경우 오후 4에서 다음날 오전 10시까지 물을 제외한 음식의 공급을 중단해 총 18시간의 단식이 되도록 하였고, 운동군의 경우 오전 8시부터 10시 15분까지 총 2시간의 수영운동(30분 운동 후 5분 휴식)을 실시하였으며, 통제군은 특별한 실험 적용을 하지 않은 상태로 실험이 진행되었다. 첫째, 그룹간 체중의 변화에서는 단식군의 18시간 단식 후의 체중과 비교해 2시간의 수영운동을 하기 전 운동군의 체중과 단식군의 18시간 단식 전의 체중에서 높게 나타났다. 둘째, 혈중 글루코스 농도는 단식군과 비교해 통제군과 운동군이 높게 나타났다. 그리고 혈중 유리지방산의 농도는 통제군에 비해 단식군과 운동군에서 높게 나타났으며, 단식군이 운동군과 비교해 높게 나타났다. 셋째, 조직 내 글리코겐 농도의 변화에서는 soleus와 EDL 모두 단식군과 비교해 통제군과 운동군에서 높게 나타났다. 하지만 조직 내 다른 요인(IL-6, Erk1/2, pErk1/2, p38MAPK)들의 변화는 나타나지 않았다. The aim of this study is to investigate the changes in cellular signaling system associated with the expression of IL-6 (interleukin-6) in blood and muscle tissue cells by the changes in body glycogen induced by swimming exercise and food intake restriction. Randomly assigned to the control group(n=12), the fasting group(n=12), and the exercise group(n=12). In addition, for the extraction of blood and tissues, the fasting group stopped supplying food except water from 4 pm to 10 am the next day for a total of 18 hours of fasting. A total of 2 hours of swimming exercise (5 minutes rest after 30 minutes of exercise) was performed in the exercise group, the control group was experimented with no special experimental application. First, the change in body weight, compared to the weight of the fasting group after 18 hours fasting, the weight of the exercise group before the 2 hours swimming exercise and the weight of the fasting group before the 18 hour fasting were higher. Second, concentration of glucose in blood were higher in the control and exercise groups than in the fasting group. The concentration of free fatty acids in blood was higher in the fasting and exercise groups than in the control group, and the fasting group was higher than the exercise group. Third, changes in tissue glycogen levels were higher the control and exercise groups than the fasting group in the sole and the EDL. However, there was no statistical difference of more than 95% in the changes of other factors in the tissues (IL-6, Erk1/2, pErk1/2, p38MAPK).

李斗馥,安景晙 홍익대학교 산업기술연구소 1998 産業技術 Vol.8 No.-
This paper deals with the design of real-time access system of field level control equipment from remote places through communication network by making links between LAN and computers which control various field equipment. The Winsock application program designed to implement simulations for the study was based on standardized Winsock program through WAN(Wide Area Network) According to the results of the study. the connection to computers linked field equipment in the laboratory from remote places through LAN. Also, searching data generated in the process of the controlling equipment on a real-time from remote place are possible through TCP/IP(Transmission Protocol/Internet Protocol) The construction of real-time data access system of field-level equipment from remote places will play an important role in sharing data and information through Internet and Intra-net which is an information network within a company.

USB 인터페이스를 이용한 필드 장비의 고속 데이터 전송 시스템 설계
李斗馥,安景晙 홍익대학교 산업기술연구소 1999 産業技術 Vol.9 No.-
The development of recent computer and communication technology has changed automation system used by communication network, and the new USB substituted with Serial Communication was already developed and now popular. In this paper, high speed data transfer system design using USB interface and communication application simulated for the situation is introduced. At the base of USB, we can use additive functions efficiently coped with former field device. The `Winsock Connection USB Terminal', designed for hardware simulation, controls the field device connected by USB, and can control the field device remotely the assistance of connection through TCP/IP. That theorem guarantees the accurate function by using sensors and field apparatus through packet communication channel of user's direct input As a result of my research, the system of operation through communication application under the condition of a former field device has in good operation. Another result of the experiment of hardware operation, we obtained the result of the sufficient bandwidth guarantee of USB with high speed and high quality comparing with serial system and of the system occupancy.
