  • This study analysis that how related to media use time before shuteye time. Excessive SNS and smatphone use were related to sleepquality and pattern. A positive correlation has been found between the time spent using smartphone before bedtime and sleep deprivation and disability phenomenon. The time spent is found to also affect the language of youths and behavioral violence.

  • Antiscratching behavioral effects of the water extract of two black colored rice (BCR) varieties [Oryza sativa L. cv. Heugjinjubyeo (HJ) and Josaengheugchalbyeo (JH)], major pigment of which is cyanindin 3-glucoside, were investigated. Orally administered BCRs' extracts exhibited potent inhibitory activity against scratching behaviors which were induced by compound 48/80 and histamine. The inhibitory effect of Josaengheugchalbyeo in vivo and in vitro were more potent than those of Heugjinjubyeo. These finding suggest that black colored rice, especially Josaengheugchalbyeo, may inhibit scratching behaviors and anaphylaxis reaction by stabilizing membrane.

  • The article formulates the key characteristics and features of country models of corporate governance. It was revealed that all countries are characterized by a fairly high concentration of ownership, insider control; Key gaps in the implementation of corporate governance principles were found: transparency and disclosure of information, protection of shareholders' rights, gender diversity of boards of directors, implementation of recommendations on the share of independent directors; The criterion of countries' efficiency (total investments) was identified and recommendations for their improvement were developed.

  • The visible threshold of Oreochromis niloticus responded to high light intensity under short wavelengths, whereas the response to low light intensity under long wavelengths was low, with a minimum visual threshold of 574 nm of LED lights. Movement distance of O. niloticus was dropped at 31℃ and increased abnormally at 37℃ under natural light. Comparing movement distance under red (622 nm) and green (518 nm) lights of LED, movement distance and swimming speed under red and green lights were higher than under natural light. However, the movement distance decreased rapidly at 31℃ under red light and lowest at 33℃ under green light. After that, there was a tendency to adapt to high water temperatures gradually. Consequently, red and green lights may be recommended for O. niloticus's aquaculture because the red and green lights have a positive effect on growth performance, survival rate, and metabolism, as shown in previous studies. It is necessary to control the water temperature below 32℃ because abnormal behavior above 32℃ revealed under red and green LED lights and natural light.

  • Climate-related events unevenly affect society, worsening mental health disparities among vulnerable populations. This paper highlights that lesbians, gays, bisexuals, transgender, queers, and other individuals identifying as sexual and gender minorities (LGBTQ+) (LGBTQ+) could be considered a climate-vulnerable population in the Philippines, one of the most climate-vulnerable countries. As such, this paper elucidated that LGBTQ+ Filipinos can be marginalized in climate response efforts due to their sexual orientation and gender minority identities. According to the minority stress theory, discrimination against LGBTQ+ individuals may predispose them to mental health problems. Thus, there is a need to institute an LGBTQ+ inclusive mental health response for climate-related events to address discrimination against LGBTQ+ individuals and uphold their mental health.

  • The purpose of this study is to evaluate dogs' sociality toward human strangers in the absence of an owner by analyzing changes in dogs' behavior during a task of making eye contact with an experimenter to obtain snacks. A total of 17 dogs were divided into groups of high sociality (HS; n = 10, 4.4 ± 3.87 years) and low-sociality (LS; n = 7, 3.71 ± 2.06 years). A comparison of the average frequency of five behavioral types-fear-appeasement behaviors (P<0.001), sociability-related behaviors (P<0.001), stress-related behaviors (P<0.05), destruction (P < 0.001), and vocalization (P < 0.001)-between the groups showed a significant difference in all five categories. Together, these results suggest that dogs with high sociality are less exposed to various stresses and have a higher ability to adapt to new environments than dogs with low sociality. This can predict dogs' adaptability to a new environment and positive outcomes in their daily life with the owner.

Is the Circadian Rhythm Dysregulation a Core Pathogenetic Mechanism of Bipolar Disorder? (일주기리듬의 조절이상이 양극성장애의 핵심 발병 기전일까?)

  • Circadian rhythm is a periodic and continuous change in physiological, behavioral, and mental characteristics that occurs in most organisms on the Earth, because the Earth rotates in a 24-hour cycle. The circadian system regulates daily rhythms of physiology and behavior, such as the sleep/wake cycle, body temperature, hormonal secretion, and mood. The influence of circadian rhythm is very powerful, but limited research has addressed its effects. However, many recent studies have shown that circadian dysregulation may play an important role in the pathogenesis of bipolar disorder. This review study examined current and noteworthy studies, including the authors' own works, and proposes a possible clinical application of bipolar disorder based on evidence that circadian rhythm dysregulation in bipolar disorder may be a key pathogenetic mechanism.

  • The corazonin (Crz) gene showed two subtypes of different length at laval and pupal stage. The long subtype fade out in adult central nerve system (CNS) but the short one survive through all the life cycle from larva to adult. The short subtype has the same base sequences with mature Crz mRNA and detected in both brain and ventral nerve cord (VNC). The long one, on the contrary, was detected only in the brain tissue. As observed in above results, Crz neurons develop in different pattern in the CNS of scuttle fly and the Crz gene expresses two different subtypes. These results suggest that this neurotransmitter may perform differential neurophysiological functions in the scuttle fly. Variation in the amino acid composition of the final active undecapeptide supports in strong those possibilities. We expect further studies on the relationship between neurophysiological functions of Crz and behavioral characteristics of the scuttle fly.

  • Occupational lung diseases (OLD) are a group of preventable conditions caused by noxious inhalation exposure in the workplace. Workers in various industries are at a higher risk of developing OLD. Despite regulations contributing to a decreased incidence, OLD remain among the most frequently diagnosed work-related conditions, contributing to significant morbidity and mortality. A multidisciplinary discussion (MDD) is necessary for a timely diagnosis. Imaging, particularly computed tomography, plays a central role in diagnosing OLD and excluding other inhalational lung diseases. OLD can be broadly classified into fibrotic and non-fibrotic forms. Imaging reflects variable degrees of inflammation and fibrosis involving the airways, parenchyma, and pleura. Common manifestations include classical pneumoconioses, chronic granulomatous diseases (CGD), and small and large airway diseases. Imaging is influenced by the type of inciting exposure. The findings of airway disease may be subtle or solely uncovered upon expiration. High-resolution chest CT, including expiratory-phase imaging, should be performed in all patients with suspected OLD. Radiologists should familiarize themselves with these imaging features to improve diagnostic accuracy.

  • Paiche (Arapaima gigas), is a colossal freshwater fish native to the Amazon basin. Its geographic distribution spans various regions, including Brazil, Peru, Colombia, and Guyana, making it a significant component of the aquatic ecosystems in this area. Beyond its ecological role, the paiche holds substantial importance as a valuable fish resource for local communities, providing sustenance and economic opportunities. This review provides a comprehensive analysis of the reproductive aspects of the paiche, based on information published from January 2000 to January 2022. It encompasses a wide range of reproductive characteristics, including sexual differentiation, age at first maturity, and identification techniques. Additionally, it offers an evaluation of various mating behaviors, highlighting their respective advantages and disadvantages. The review also explores genetic and behavioral traits observed in both wild and captive specimens, offering valuable insights for the effective management of breeding programs.
