The severity of smartphone dependence among early adolescents, known as the most vulnerable group to smartphone addiction, is increasing. In this study, the factors affecting the smartphone dependence of early adolescents were analyzed by separating into elementary school and middle school students. For this purpose, the 1st data from Korean Children and Youth Panel Survey(2018) was used. The subjects of the study were 2,607 4th grade from elementary school and 2,590 1st grade from middle school. Factors that affect to smartphone dependence of both elementary and middle school students in common were gender, self-esteem, aggression, time spent with parents, and negative parenting attitude. On the other hand, region(city size), economic level, health status, school life satisfaction, and relationship with teachers were significant in the smartphone dependence of elementary school students, but not in middle school students. In middle school students, positive parenting attitudes were significant. Based on the results of the analysis, implications for policy establishment and social service provision were drawn to encourage the proper use of the by early youth.

Salmonella enterica subsp. enterica serovar Enteritidis is a major food-borne pathogen responsible for severe economic loss in the poultry industry. We report the complete genome sequence of the novel bacteriophage (phage) vB_SenAt-pSL2 infecting Salmonella enterica subsp. enterica serovar Enteritidis KCTC 82777 isolated from Korean broiler chickens. The genome comprised a linear double-stranded DNA of 44,304 bp with 47.4% G + C content and 54 ORFs. Genome-based comparison revealed that the phage was closely related to Zindervirus and distinguished by having the largest genome in the genus. The high nucleotide similarity of the predicted tail fiber and spike proteins in vB_SenAt-pSL2 with other broad-host-range phages in Zindervirus suggests its potential to infect diverse Salmonella serotypes. Based on these results, the newly isolated Salmonella phage vB_SenAt-pSL2 is a new member of the genus Zindervirus and its genomic information provides insights into the biodiversity and taxonomy of Autographiviridae.

Vibrio parahaemolyticus associated with acute hepatopancreatic necrosis disease (Vp<sub>AHPND</sub>) and Enterocytozoon hepatopenaei (EHP) are the two most important pathogens in shrimp aquaculture and they have caused enormous losses to the shrimp industry worldwide. In ponds, the major target organ for the two pathogens is the hepatopancreas, and infection with EHP is a known potential risk factor for Vp<sub>AHPND</sub> infection. This study aimed to develop a PCR (polymerase chain reaction)-based diagnostic method for simultaneously detecting Vp<sub>AHPND</sub> and EHP. The newly developed PCR diagnostic method could be used to test various samples, such as seawater, shrimp, and feces. The diagnostic method exhibited high sensitivity and specificity for both pathogens. This will help reduce the potential economic losses that may have been caused by the two major shrimp pathogens, Vp<sub>AHPND</sub> and EHP, and will allow for the efforts and time spent combatting them to be dedicated elsewhere.
