In this paper, applicability of SI-PD(switching impulse - partial discharge) testing method was put on an attempt as a newly proposed diagnostic method for the underground distribution power cable system in Korea. For this purpose, SI-PD testing equipment was designed, and tests were performed using artificial needle-type defects integrated into the 22.9 kV CN/CV cables in drder to prove its reliability. As a result, arc noises, generated from spark gap, were considerably decreased by use of a pneumatic switch immersed into oil, and artificial needle-type defects were well detected with impulse voltage level under $2U_0$. These results imply that it is likely possible to apply SI-PD measurement method as a the nondistructive test for the 22.9 kV CN/CV cable system in Korea.

Porcine epidemic diarrhea virus (PEDV) strain Chinju99, which was previously isolated from piglets suffering from severe diarrhea was used to characterize the membrane (M) protein gene to establish the molecular information, and the results will be useful in elucidating concepts related to molecular pathogenesis and antigenic structures of PEDV isolates. The Chinju99 M gene generated by reverse transcription and polymerase chain reaction (RT-PCR) consisted of 681 bases containing 22.3% adenine, 22.3% cytosine, 23.1% guanine and 32.3% thymine nucleotides, and the GC content was 45.4%. It had some nucleotide mismatches from M gene of other PEDV strains, such as CV777, Br1/87, KPEDV-9, JMe2, JS2004-2 and LJB-03 with 97-99% nucleotide sequence homology to these strains. Also, it encoded a protein of 226 amino acids, which had some mismatches from those of CV777, Br1/87, KPEDV-9, JMe2, JS20004-2 and LJB-03, as the amino acid sequence homology showed a 97-98% to these strains. The Chinju99 had a very close relationship to the Japanese strain JMe2 for the nucleotide and amino acid sequences of the M gene. The amino acids predicted from Chinju99 M gene consisted of mostly hydrophobic residues and contained three potential sites for asparagine (N)-linked glycosylation, two serine (S)-linked phosphorylation sites by protein kinase C, and two S- or threonine (T)-linked phosphorylation sites by casein kinase II.

Objectives : The purpose of this study is to investigate acupoints that appear in ancient records and use with regard to treatment to the wheezing and dyspnea. Methods : We investigated 10 ancient records from Song Dynasty to the Qing Dynasty that had medical references to wheezing and dyspnea. Results and Conclusions : Out of acupoints that found out to be used for treatment of wheezing and dyspnea in this study, Conception and Governor channels account for 38.9%, the three yang meridians of the foot account for 22.2% and the three tin meridians of the Hand account for 13.9%. In 10 ancient records, CV22(Tian tu) appears 5 times, CV12(Zhongwan) and ST36(Zusanli) appear 4times. A total number of acupoints that appear in the ancient records were 35. In compendium of medicine, the number of acupoints was 21. In cmpendium of acupuncture and moxibustion, the number of acupoints was 10. In the treatment of wheezing and dyspnea, not only acupuncture but also moxibustion has a great importance.

In this paper, we present a solution to the problems caused by using only text - based information as an index element when a commercialized missing person indexing system indexes missing persons registered in the database. The existing system could not be used for the missing persons inquiry because it could not formalize the image of the missing person registered together when registering the missing person. To solve these problems, we propose a method to extract the similarity of images by using OpenCV image processing and TensorFlow deep - running image processing, and to process images of missing persons to process them into meaningful information. In order to verify the indexing method used in this paper, we constructed a Web server that operates to provide the information that is most likely to be needed to users first, using the image provided in the non - regular environment of the same subject as the search element.

The high-performance liquid chromatography(HPLC) method for the determination of trans-resveratrol in 34 germplasms and processing methods of peanut seeds has been modified. Peanut germplasms contained trans-resveratrol contents of $0.14{\sim}4.96{\mu}g/g$, but findings for the testa color were not significant. However, two germplasms, 'KIGAN' and 'CS1', contained more trans-resveratrol contents than the other germplasms. The contents of their were $2.26{\mu}g/g\;and\;4.96{\mu}g/g$. The tested processing methods caused no significant changes in trans-resveratrol contents. The contents of fresh, boiled, and roasted peanuts were 0.36, 0.32, and $0.40{\mu}g/g$, respectively in cv. Palkwang, and 0.22, 0.22, and $0.26{\mu}g/g$, respectively, in cv. Jakwang. Differences were not significant among fresh, boiled, and roasted peanuts. The grains of 'Palkwang' and 'Jakwang' contained trans-resveratrol contents of $0.34{\mu}g/g\;and\;0.24{\mu}g/g$, and testa contained $1.12{\mu}g/g\;and\;1.00{\mu}g/g$, respectively. However, when comparing absolute quantity, the trans-resveratrol contents appears to be approximately $3{\sim}4$ times higher in the testa than in the grain of the peanut, although the total contents were not different because the ratio of testa was low in peanut seeds.

Objectives : The prevalence of chronic cough in Korea is 2.5 ± 0.2% among people over the age of 40, and the rate of idiopathic chronic cough is high. Hemoptysis is one of the respiratory emergency symptoms, and the cause is unknown in 30% of cases. This case report is to confirm the treatment of korean medicine for Idiopathic chronic cough and hemoptysis. Methods : A 74 year old female patient with idiopathic chronic cough and hemoptysis was treated with korean medicine. The patient was treated from july 21, 2021 to september 24, 2021, using herbal medicine (Chungpyebyeolgab-sangagam) and acupuncture(Sa-Am Acupunture Lung Tonifying, CV22). Idiopathic chronic cough and hemoptysis were assessed by VAS. Results : Idiopathic Chronic cough and hemoptysis improved through Korean medicine treatment. Although taking codeine phosphate and transamin was stopped, the improvement of symptoms was maintained. Conclusions : This study suggests that korean medicine treatment may be an effective therapy for treatment of idiopathic chronic cough and hemoptysis.

The FSA(Force Sensitive Application) system measures hand force by using force resistance sensors. Compared to conventional hand force measurement systems such as Lafayette hand dynamometer and Jamar hydraulic hand dynamometer, the FSA system can be applied to analyze use of hand forces while the hand is manipulating objects for a task, However, the measurement performance of the FSA system has not been objectively evaluated. The present study tested the FSA system in terms of stability, repeatability, accuracy, and linearity. It is shown that the FSA system has good stability (CV$\leq$0.02) and linearity($R^2$=0.82), but has low repeatability(CV=$0.11{\sim}0.19$) and accuracy(22% of underevaluation on average). This performance result indicates that measurements from the FSA system should be used for relative comparison rather than for absolute comparison.

In this paper, we studied the diagnostic method of insulation deterioration for 22.9kV CNCV cable using D.C potential decay component. At first, arbitrary D.C high voltage is appeied the CNCV cable for two minutes and switched off in vacuum. And then D.C potential decay components is measured for ten minutes. It is detecting source for cable insulation deterioration that its gradient is. Provisionally, we decided the criterion voltage and select the high voltage meter and S.W.
