  • This study aimed to examine the effect of external pop-up satellite archival tags (PSATs) attachment and water temperature on the oxygen consumption rate (OCR) of the olive flounder (mean body weight 2281.7 g). The OCRs of fish were measured under conditions of three different water temperature conditions (15, 20, and 25℃) and two different tagging methods [non-tagging, control; bio-logger external attachment with a miniature PSAT (dummy mrPAT), BEA] using a closed flow-through respirometer. The OCRs of fish linearly increased with the increase in water temperature in both the control and BEA (P<0.001); however, the OCRs of BEA were approximately 1.8-1.9 times lower than those of the control at each water temperature (P<0.001). The Q10 values of the control and BEA were the highest in the water temperature range of 15 to 20℃, but sensitivity to water temperature changes was higher in BEA than in the control. The metabolic energy loss rate (MEL) of fish increased with increasing water temperature regardless of external tagging, but the MEL of the control was higher than that of BEA (P<0.001). These results demonstrate that OCR, thermal sensitivity, and energy expenditure are all affected in adult olive flounder with external PSAT attachment.

  • Tick infestation causes a significant threat to human and animal health, requiring effective immunological control methods. This study aimed to investigate the potential of recombinant Haemaphysalis longicornis enolase protein for tick vaccine development. The exact mechanism of the recently identified enolase protein from the H. longicornis Jeju strain remains poorly understood. Enolase plays a crucial role in glycolysis, the metabolic process that converts glucose into energy, and is essential for the motility, adhesion, invasion, growth, and differentiation of ticks. In this study, mice were immunized with recombinant enolase, and polyclonal antibodies were generated. Western blot analysis confirmed the specific recognition of enolase by the antiserum. The effects of immunization on tick feeding and attachment were assessed. Adult ticks attached to the recombinant enolase-immunized mice demonstrated longer attachment time, increased bloodsucking abilities, and lower engorgement weight than the controls. The nymphs and larvae had a reduced attachment rate and low engorgement rate compared to the controls. Mice immunized with recombinant enolase expressed in Escherichia coli displayed 90% efficacy in preventing tick infestation. The glycolytic nature of enolase and its involvement in crucial physiological processes makes it an attractive target for disrupting tick survival and disease transmission. Polyclonal antibodies recognize enolase and significantly reduce attachment rates, tick feeding, and engorgement. Our findings indicate that recombinant enolase may be a valuable vaccine candidate for H. longicornis infection in experimental murine model.

  • In the treatment of chronic adult periodontitis, scaling and root planing have been generally performed prior to periodontal flap surgery. The purpose of this study was to evaluate the clinical significance of nonsurgical periodontal therapy prior to periodontal flap surgery in patients with chronic adult periodontitis. Fifty six molars showing bilateral bony defects and 4-6mm periodontal pocket in twelve patients with chronic adult periodontitis were selected. By randomized split-mouth design, in one side, flap operation was performed 4 weeks after scaling and root planing, in the other group, flap operation was only performed without scaling and root planing. Probing pocket depth, gingival recession, clinical attachment level, gingival index, plaque index, and tooth mobility were measured at baseline, before flap operation and post-operation

  • Kelp life history pathways alternate between macroscopic sporophytes that produce spores and microscopic gametophytes that produce gametes. Occasionally, an alternative pathway is seen. This study examined the circumstances by which the high latitude estuarine bull kelp, Nereocystis luetkeana, foregoes the "free-living microscopic stages by releasing embryonic sporophytes directly from sori. Sori were collected from adult N. luetkeana sporophytes from eight locations within Kachemak Bay, Alaska in 2018 and 2020 to examine spatial and temporal development of embryonic sporophytes on sori. Distinctions were made between sori collected from first-generation and overwintered adults to assess the influence of parental age on embryonic sporophyte release. Further distinctions were made between sori collected from attached and drifting individuals to assess the influence of the status of parental attachment to substrate on embryonic sporophyte release. Inspection of propagules released from sori after 48-h incubations indicated that embryonic sporophytes were occasionally released alongside viable spores. Though embryonic sporophytes were released from sori as early as spring, it was not evident that they were bound by seasonal or spatial limits. The percent of propagules that were embryonic sporophytes ranged from 0% to 100% but were not significantly different between first-generation and overwintered adults, nor were they different between attached and drifting individuals. Nevertheless, the characteristic of directly releasing embryonic sporophytes from adult sporophytes might have ecological advantages for N. luetkeana.

  • Ultrastructural study of the development of the atrioventricular (AV) node was studied by electron microscopy in human fetus ranging from 30 mm to 260 mm crown rump length, and compared with human adult. By 30 mm fetus, the right AV nodal primordium was located below the attachment of the right venous valve. The left AV nodal primordium was observed below the attachment of septum primum. The cytoplasm of the nodal primordia contained few mitochondria, and myofibrils. These cells were apposed to each other with occasional desmosomes. In 40 mm fetus, the AV node cells were poorly organized myofibrils, while working myocardial cells were well organized myofibrils with sarcomere. At 70 mm fetus, intercalated discs were developed in the working myocardial cells. At 100 mm fetus, the nodal cells contained a relatively clear cytoplasm with a few groups of myofibrils and mitochondria. By $140\sim200$ mm fetuses, the nodal cells were an increasing number of myofibrils and mitochondria and these were scattered throughout the cytoplasm. At 260 mm fetus, the nodal cells were small and contained a clear cytoplasm with sparse and poorly organized myofibrils and mitochondria. All major ultrastructural features which characterize the adult AV nodal cells were found in this stage. The working myocardial cells were larger and had a more compact cytoarchitecture than nodal cells. Zonula adherens or fasciae adherens type junction were not found between nodal cells, but they frequently observed between nodal and working myocardial cells.

  • This study explored in-depth emotional experiences influenced by childhood trauma of adult female survivors. For this purpose, in-depth interviews were conducted with married adult women who experienced trauma in their childhood. The collected data were analyzed using Colaizzi phenomenological research method. As a result of the study, 7 categories were derived: 'children who cannot protect themselves', 'childhood trauma,' 'insecure attachment and good child syndrome,' 'difficulties in interpersonal relationships,' 'difficulties in raising children,' 'somatization symptoms,' 'finding myself who is lost.' In addition, this study aims to understand the psychological experience of children in the family and the relationship between parents and children and the growth experience of healing them by comparing and contrasting the two cases of trauma. The foundation for healthy ego-resilience and emotional well-being has been laid through the research results on negative and maladaptive emotional experiences reflected throughout the life of adult women who suffered childhood trauma.

  • The purpose of this study is to find out the dimensions of kidult fashion emotion and identify the influence of socio-psychological characteristics(nostalgic orientation, change inclination, and self-esteem) on kidult fashion emotion. 'Kidult', composite of kid and adult is indicating a group of people who feel nostalgic for and feel attachment to the products that they have been used in their childhood. A questionnaire was prepared in the survey and a total of 474 women in their twenties and thirties who had purchased the kidult fashion products were selected. The research findings are as follows: 1. Kidult fashion emotion can be classified as 5 factors: pursuits of fashion emotion, seeking girlish image emotion, preference for character emotion, seeking fun emotion, and past oriented emotion. 2. Socio-psychological variable that affected kidult fashion emotion is turned out change inclination. 3. The higher the seeking girlish image and pursuit of fashion emotion tendencies, the more they purchase the kidult fashion products. Based on these results, kidult fashion emotions are not the attachment to the past but positive expression of self and individuality.

  • In order to determine the relationship between probing pocket depth and trypsin-like activity in subgingival plaque, probing pocket depth and loss of attachment were measured by Michigan-O probe on mandibular incisors of 30 patients with adult periodontitis. And the trypsin-like activity of Treponema denticola, Porphyromonas gingivalis, and Bacteroides forsythus was evaluated by the hydrolysis of N-Benzoyl-DL-Arginine-2-Naphthyla-mide (BANA) using PerioScan reagent cards(Oral-B Laboratories, Redwood City, CA). The obtained data were statistically analyzed by Microstat program. The results were as follows. 1. The number of teeth showing negative trypsin-like activity was more in shallow periodontal pocket groups, but the number of teeth showing positive trypsin-like activity was more in deep periodontal pocket groups. 2. There was a significant positive correlation between probing pocket depth and trypsin-like activity in subgingival plaque(y=0.413X - 0.955, r = 0.7024, p<0.001). 3. There was no consistent relationship between loss of attachment and trypsin-like activity in subgingival plaque(p>0.01).
