Individual identification of severely decomposed or skeletonized bodies is an important part in medicolegal field. 142 bodies were torn up and carried away by flood in a park cemetry, Kwang-Ju, Kyunggi province, Korea at Sept., 10, 1990. The authors examed the 56 bodies, which were gained, through medical, anthropological, odontological, radiological methods, and superimposition for individual identification. Among them, 41 cases were successfully identified, and remaining 15 cases were not identified because of sever destruction and no adequate information.

<P><B>Purpose</B></P><P>This study aimed to investigate the effects of single-bout exercise on mitochondrial function, dynamics (fusion, fission), and mitophagy in cardiac and skeletal muscles.</P><P><B>Methods</B></P><P>Fischer 344 rats (4 months old) were randomly divided into the control (CON) or acute exercise (EX) group (n=10 each). The rats performed a single bout of treadmill exercise for 60 minutes. Mitochondrial function (e.g., O<SUB>2</SUB> respiration, H<SUB>2</SUB>O<SUB>2</SUB> emission, Ca<SUP>2+</SUP> retention capacity), mitochondrial fusion (e.g., Mfn1, Mfn2, Opa1), mitochondrial fission (e.g., Drp1, Fis1), and mitophagy (e.g., Parkin, Pink1, LC3II, Bnip3) were measured in permeabilized cardiac (e.g., left ventricle) and skeletal (e.g., soleus, white gastrocnemius) muscles.</P><P><B>Results</B></P><P>Mitochondrial O<SUB>2</SUB> respiration and Ca<SUP>2+</SUP> retention capacity were significantly increased in all tissues of the EX group compared with the CON group. Mitochondrial H<SUB>2</SUB>O<SUB>2</SUB> emissions showed tissue-specific results; the emissions showed no significant differences in the left ventricle or soleus (type I fibers) but was significantly increased in the white gastrocnemius (type II fibers) after acute exercise. Mitochondrial fusion and fission were not altered in any tissues of the EX group. Mitophagy showed tissue-specific differences: It was not changed in the left ventricle or white gastrocnemius, whereas Parkin and LC3II were significantly elevated in the soleus muscle.</P><P><B>Conclusions</B></P><P>A single bout of aerobic exercise may improve mitochondrial function (e.g., O<SUB>2</SUB> respiration and Ca<SUP>2+</SUP> retention capacity) in the heart and skeletal muscles without changes in mitochondrial dynamics or mitophagy.</P>

Aiming at the problem that the load disturbance generated by the permanent magnet synchronous linear motor (PMSLM) control system will affect its control performance and the load thrust of the PMSLM cannot be observed well, this design proposes two different load disturbance observers, namely the traditional Luenberger observer and novel internal model control (IMC) observer. The IMC observer observes the load disturbance in the form of proportional and integral, which can effectively improve the identification convergence speed and the compensation control effect. While observing the load disturbance, the two observers in this design can also use the generated thrust current compensation as the feedforward compensation of the system, to achieve disturbance suppression and effectively improve the control performance and robustness of the system. The PMSLM control system based on two observers is built in the simulation platform and the superiority of the designed control system is verified. Through the comparison and verification of the two observers and the no-observer system, it can be concluded that the control strategy can accurately track the load disturbance in the PMSLM, simplify the overall structure of the system, and effectively enhance the anti-disturbance capability and dynamic response capability of the PMSLM.
