  • The respiration rate of Chinese quince was measured at 0, 5, 10, and $20^{\circ}C$ to determine its tolerable range of storage temperatures. Based on the measured respiration rates, plastic films covering a wide range of gas permeabilities were used for packaging and storing individual Chinese quince at 0 and $10^{\circ}C$. Chinese quince can be categorized as low respiration fruit. Higher respiratory quotients were observed at higher temperature suggesting that the tolerable temperature range for storage is $0-10^{\circ}C$. Packages containing Chinese quince wrapped in highly gas-permeable polyolefin film PD 941 attained, with progressive decreases in volume, 9.5-10.2% $O_2$ and 1.3-1.8% $CO_2$ at $0^{\circ}C$, 8.1% $O_2$ and 2.4% $CO_2$ at $10^{\circ}C$. At these levels, PD 941 could preserve the fruit at acceptable quality levels for 152 and 50 days at 0 and $10^{\circ}C$, respectively. Less gas-permeable packages built up high $CO_2$ concentrations (above 15.8%) and low $O_2$ concentrations (less than 1.8%) causing free volume expansion and eventual dark discoloration of the fruit. The storage life realized by packaging with polyolefin film PD 941 could facilitate the availability of Chinese quinces in winter and spring for medicinal or ornamental purposes in the fresh state.

  • The aim of this article is to investigate the religious medical treatments performed by Kang Jeungsan as recorded in The Canonical Scripture, the main scripture of the Korean new religion, Daesoon Jinrihoe. The unity of mind and body is the core principle underlying Kang Jeungsan's religious medical treatments. He believed treating the mind of his patients was more important and necessary than treating their diseases. As such, he believed the only way to treat critical illness was to keep preserve the mind-body unity of his patients. Massage was a physical therapy often used by Kang Jeungsan. The medicinal materials that he commonly used were the Four-substance Decoction (四物湯 samultang), Minor Bupleurum Decoction (小柴胡湯 soshihotang), quince (木瓜 mokgwa *Pseudocydonia sinensis; not papaya), and rehmannia (生地黃 saengjihwang). Kang Jeungsan's religious medical treatments were characteristic of Daoist healing methods. His Daoist style healing methods included multiple techniques such as treating diseases through correcting Qi, exorcising malevolent entities, transferring diseases to a different host, removing a disease through the changing of clothes, pouring medicine into the ground, combining the usage of talisman and incantations, and treating the common people. Among these techniques, Jeungsan's pouring medicine into the ground was especially innovative.

  • Several genera belonging to the family Acetobacteraceae were generally considered to be acetic acid bacteria (AAB) which produce acetic acid from alcohols using an oxidation pathway. Some species of the family Acetobacteraceae have been of interest to the industry due to their capability to produce vinegar. In 2018-2020, several bacterial strains were isolated from plants, fruits and vinegar in various regions of the Republic of Korea. Based on the 16S rRNA gene sequences, seven species classified into the family Acetobacteraceae were found to be ones unrecorded in the Republic of Korea, including two Asaia species, one Gluconacetobacter species, three Gluconobacter species and one Komagataeibacter species. As a result, we report Asaia lannensis AF11C3 (=KACC 22050) isolated from plant Chrysanthemum zawadskii, Asaia platycodi AF15C2 (=KACC 22051) isolated from plant Isodon inflexus, Gluconacetobacter liquefaciens C23-3 (=KACC 22064) isolated from fruit of Pyrus pyrifolia, Gluconobacter cerinus BGF2-R2 (=KACC 22053) isolated from fruit of Prunus armeniaca, Gluconobacter kondonii FR39A4 (=KACC 22388) isolated from persimmon fruit, Gluconobacter thailandicus FR36C4 (=KACC 22057) isolated from fruit of Pseudocydonia sinensis and Komagataeibacter melaceti SPV-2 (=KACC 22058) isolated from potato vinegar.
