Feline calicivirus (FCV) infection results in a common upper respiratory disease associated with oral ulceration in cats. Although FCV infection has been reported in cats worldwide, the biologic and genetic features of South Korean FCV are unclear. We aimed to investigate the biological and genetic features of South Korean FCV isolates. Crandell-Rees feline kidney (CRFK) cells were used to isolate FCV from 58 organ homogenate samples. The FCV isolates were confirmed by cytopathic effects, immunofluorescence, electron microscopy, and reverse transcription polymerase chain reaction assays. Viral genetic analysis was carried out with VP2 gene and complete genomes of FCVs. Five viruses propagated in CRFK cells were confirmed to be FCVs. The FCV17D283 isolate showed the highest viral titer of 107.2 TCID50/mL at 36 h post-inoculation. Korean FCV isolates did not grow well in Vero, BHK-21, A72, or Madin-Darby canine kidney cells. The FCV17D03 and FCV17D283 isolates had the highest genetic similarity (80.1% and 86.9%) with the UTCVM-H1 and 14Q315 strains, which were isolated in the United States and South Korea in 1995 and 2014, respectively. We isolated five FCVs from cats and detected important genetic differences among them. FCV isolates did not show any virulent effects in mice.

The scope of fire services has been expanded from local fire prevention to rescue and first aid services, and the fire services system has been converted from an autonomous fire services system to a wide-area fire services system, and the status of fire officers has been unified as a national public servant. However, the underlying problem remains unsolved. One is a problem related to the conversion of fire services to state affairs, and the other is that Fire officers converted to national public servants are in charge of fire services which are evaluated as local autonomous affairs. The controversy over the nature of fire service stems from uncertainty and redundancy in the coordination of office function and distribution between the State and Local governments, and incomplete legislation that fundamentally fails to achieve systematic unity of office work and status. The fire service has a national responsibility as an affair that includes the existence of the state and the welfare and order of the people along with the police affairs. That is, affairs related to the safety of the people that protect the lives, bodies and properties of the people should be understood as State affairs. 「The LOCAL AUTONOMY ACT」 stipulates that local governments cannot perform State affairs such as affairs necessary for the existence of the nation, affairs requiring performance in a uniform manner throughout the nation, and affairs of nationwide or similar scale unless otherwise provided by the law. Fire Service should be regarded as such affairs. Considering that the rights to the safety and life of the people and the duty to protect the people are the duty of the nation, it is necessary to keep in mind that the reason for the change fire officers to the national public servants was not basically just a matter of treatment and finance.

Background: Canine distemper virus (CDV) infection results in high morbidity and mortality in dogs. There has been no report about Isolation of Korean CDV since 1980 in Korea. Objectives: To investigate the biological properties and the genetic characterization of Korean CDV. Methods: Vero cells expressing dog signaling lymphocyte activation molecule (dSLAM) gene named as Vero/dSLAM were used to isolate CDV using 17 samples. Diagnostic methods such as cytopathic effects, immunofluorescence assay, peroxidase linked assay, electron microscopy, rapid immunodiagnostic assay, and reverse transcription polymerase chain reaction were used to confirm the Korean CDV isolate as a CDV. The genetic analysis was performed through cloning and sequencing of hemagglutinin gene of CDV isolate. Results: A virus propagated in Vero/dSLAM cell was confirmed as CDV (CD1901 strain) based on the above methods. The CD1901 strain showed the highest viral titer (10^5.5 50% tissue culture infectious dose [TCID₅₀]/mL) in the Vero/dSLAM cells at 4 days post inoculation, but did not form a fork on chorioallantoic membrane of 7-day-old egg. Ribavirin, a nucleotide analogue anti-viral agent, inhibits moderately the Korean CDV propagation in the Vero/dSLAM cells. The nucleotide and amino acid sequences of the H gene of CD1901 strain were compared with those of other CDV strains. The CD1901 strain belonged to Asia 1 group and had the highest similarity (99.9%) with the BA134 strain, which was isolated in China in 2008. Conclusions: We constructed successfully Vero/dSLAM and isolated one Korean CDV isolate (CD1901 strain) from a naturally infected dog. The CD1901 strain belonged to Asia 1 genotype.

This study was undertaken to evaluate the impact of Chinese cinnamon powder (w/w), at the levels of 0.5%, 1.5%, and 2.5% and control (without additive) on ground lamb meat quality. The samples were stored at 4℃ and examined for pH, color, lipid oxidation (thiobarbituric acid reactive substances) and total viable counts (TVC). The results demonstrated that pH values were declined with the increase of Chinese cinnamon levels compared to control group. The L* values throughout the storage were significantly higher (p<0.05) in the control group than in other treatment groups, while a* values were decreased with the increase of Chinese cinnamon levels. The addition of Chinese cinnamon powder strongly inhibited (p<0.05) thiobarbituric acid reactive substances (TBARS) and TVC in all treated samples. It can be concluded that Chinese cinnamon powder in lower concentration 0.5% has the ability to maintain the quality of ground lamb in comparison with other treated samples.

Two new diphenylethylenes, gramniphenols H and I (1 and 2), together with six known diphenylethylenes (3-8), were isolated from Arundina graminifolia. The structures of 1-8 were elucidated by spectroscopic methods including extensive 1D- and 2D-NMR techniques. Compounds 1 and 2 were evaluated for their cytotoxicity against five human tumor cell lines. Compound 1 showed cytotoxicity against PC3 cells with $IC_{50}$ value of 3.5 ${\mu}M$. Compound 2 showed cytotoxicity against NB4 and PC3 cells with $IC_{50}$ values of 3.6 and 3.8 ${\mu}M$, respectively.

Objectives : This study aimed to evaluate adverse outcome associated with acupotomy and compare it with that of acupuncture. Methods : We retrospectively analyzed the chart records of 71 patients who received acupotomy at Daemyung Korean medical clinic from January 7, 2020 to March 6, 2020. We divided the acupotomy treatment area into 10, including the head, hand, chest, knees, shoulders, low back, neck, upper extremities, thighs, and feet. Furthermore, we investigated the adverse effect of acupotomy on those areas after treatment. Data were analyzed using descriptive statistics, and frequency analysis. Results : 'Bruise of specific region' accounted for the largest portion with 29 cases, followed by 24 cases of 'feeling tired and sleepy' and 17 cases of 'itch'. There were 16 cases of 'sustained pain' at the area of treatment, 11 cases of 'fatigue', 5 cases of 'swelling', 5 cases of 'dizziness', 4 cases of 'hematoma'. There were 3 cases of 'vertigo' and 2 cases of 'parathesia' and 'wide bruises', 'headache', 'gastric discomfort', 'bleeding', and 'skin rash' each. There was one case each that experienced 'unclear pronunciation', 'nausea', 'abnormal sweating', 'vomiting' and 'emotional/psychological reactions'. Conclusions : Adverse outcomes associated with acupotomy were mostly 'bruise of specific region', 'feeling tired and sleepy', 'itch', 'sustatained pain', and 'fatigue'. However, no adverse outcome or irreversible damage that have a serious effect on the body were observed.

This research was focused on wives and theirs husbands who have been involved in extramarital affairs. The major purpose of this study was to find out wives' marital adaptation process and typology in the process of their husbands' affairs. The grounded theory provided the theoretical and methodological framework for this research. The qualitative data were obtained from ten wives whose husbands have had extramarital affairs through in-depth interview. The data wear analyzed through open, axial, and selective codings and formed a conditional matrix. This research classified these wives' adaptation into four types such as Separated Independent, Rigid Resigned, Connected Acceptive, and Chaotic Attached types.
