The strain BT320 was closely related to Flavisolibacter galbus 17J28-26 (97.

Flaviaesturariibacter aridisoli sp. nov., A Bacterium Isolated from Dry Soil.

A novel bacterial strain, designated 17J68-15, was isolated from dry soil collected in Jeju Island, South Korea. Cells of strain 17J68-15 are Gram-negative, pale-yellow-colored, non-motile, non-spore-forming, rod-shaped was able to grow at 18-42 °C with 0-1% NaCl on R2A agar. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the strain was distinct from any previously known species of the genus Flaviaesturariibacter.

Spirosoma aureum sp. nov., and Hymenobacter russus sp. nov., radiation-resistant bacteria in Cytophagales order isolated from soil.

A Gram-stain-negative, aerobic, nonmotile, yellow-colored strain BT328 and Gram-stain-negative, aerobic, non-motile, red-colored strain BT18 were isolated from the soil collected in Korea. Phylogenetic analyses based on 16S rRNA gene sequence revealed that strain BT328 formed a distinct lineage within the family Spirosomaceae (order Cytophagales, class Cytophagia) and was most closely related to a member of the genus Spirosoma, Spirosoma terrae 15J9-4 (95.9% 16S rRNA gene sequence similarity).

Rhodocytophaga rosea sp. nov. and Nibribacter ruber sp. nov., two radiation-resistant bacteria isolated from soil.

Two bacterial strains, 172606-1 and BT10, were isolated from soil, Korea. Both strains were Gram-stain-negative and rod-shaped bacteria. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain 172606-1 formed a distinct lineage within the family Cytophagaceae (order Cytophagales, class Cytophagia, phylum Bacteroidetes).

Noviherbaspirillum galbum sp. nov., a bacterium isolated from soil.

A Gram-stain-negative, aerobic, non-motile and yellow-colored bacterium, strain 17J57-3, was isolated from soil collected in Pyeongchang city, Korea. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain 17J57-3 formed a distinct lineage within the family Oxalobacteraceae (order Burkholderiales, class Betaproteobacteria). Strain 17J57-3 was the most closely related to Noviherbaspirillum humi U15 (96.

Pontibacter fetidus sp. nov. and Pontibacter burrus sp. nov., isolated from the soil.

Two novel strains, BT213 and BT327, were isolated from the soil collected in Uijeongbu city, Korea. Cells of strains were Gram negative, aerobic, and non-motile. Phylogenetic analysis based on 16S rRNA gene sequences showed that strains BT213 and BT327 formed two distinct lineages within the family Hymenobacteraceae (order Cytophagales, class Cytophagia).

Adhaeribacter soli sp. nov., a bacterium isolated from soil in Korea.

Strain MA2 was isolated from a soil sample from Gijang-gun, Busan in Korea. The strain, a Gram-stain-negative aerobic bacterium, is non-motile, ovoid- or rod-shaped, catalase- and oxidase-positive, and grows at NaCl concentrations 1% (w/v), at 15-30 °C (optimum 25 °C) and at pH 6-8.5 (optimum pH 7.

Pontibacter pudoricolor sp. nov., and Pontibacter russatus sp. nov. radiation-resistant bacteria isolated from soil.

Gram-stain-negative, aerobic, non-flagellated, red-colored strains BT214 and BT326 were isolated from soil collected in Uijeongbu city, Korea. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strains BT214 and BT326 formed a distinct lineage within the family Hymenobacteraceae (order Chitinophagales, class Chitinophagia) and were most closely related to members of the genus Pontibacter, Pontibacter populi HLY7-15 (96.9% 16S rRNA gene sequence similarity) and Pontibacter amylolyticus 9-2 (96.

Development and Validation Study of the Internet Overuse Screening Questionnaire.

Objective: Concerns over behavioral and emotional problems caused by excessive internet usage have been developed. This study intended to develop and a standardize questionnaire that can efficiently identify at-risk internet users through their internet usage habits.

Methods: Participants (n=158) were recruited at six I-will-centers located in Seoul, South Korea.

The relationship of problematic internet use with dissociation among South Korean internet users.

This study examined patterns of problematic internet use (PIU) among South Korean internet users to investigate the association between PIU and dissociative experiences. Five hundred and eight participants between 20 and 49 years old were recruited through an online panel survey. Using logistic regression analysis with PIU as the dependent variable, we observed that the participants with PIU were more likely to have alcohol-related behaviors or problems, higher levels of perceived stress, and dissociative experiences.
