Feeding of the maiden goby, Pterogobius virgo and multicolorfin rainbowfish, Halichoeres poecilopterus, was studied at Kurahashi Island in the Seto Inland Sea, Japan. P. virgo foraged on only benthic invertebrates in a pit on the bottom by spot-fixed fin digging. Territory size of P. virgo was very small, because they only defended the excavated pit. H. poecilopterus frequently intruded into the feeding territory of P. virgo and fed on benthic invertebrates flushed out by the fin digging of P. virgo. Feeding activity and vigilance time of P. virgo tended to decrease significantly more in such an association than when solitary. Frequency of aggression of P. virgo when H.poecilopterus intruded into the territory was higher the intruder came from the front of the territory than when the invasion was from the side and back, regardless of the size of the intruder. In small H.poecilopterus, feeding success rate was greater from the side and back of the territory than from the front. However, similar-sized H.poecilopterus were more successful in feeding from the front and side. Feeding association provides an antipredatory benefit to P. virgo because of less alert time against predators and earlier detection of predators, although their cost is great because of territory defense and decrease of feeding activity.
This study has verified the process of helping actors recognize their sexual problems linked to sexual violence cases through early sexual experience history, and exploring and insighting the stuck feelings of sexual violence actors through psychodrama, which focuses on expressing behavior and emotions. The research questions were divided into sexual violence cases and perceptions of actors, actual insights through psychodrama, and dealt with past biblical history related to actors' events and events, exploration of childhood trauma, and insights and changes in emotions through psychodrama. The results from the study are as follows. First, they showed low self-understanding levels and frequent use of defense mechanisms against sexual violence cases in an environment related to cases involving sexual offenders, and were aware of the problematic factors affecting the cases in the course of their daily lives, but did not take them seriously. Second, there were many distorted masculinity and adult sites related to participants' biblical experience history. In the early experience of sexual activity, it was often viewed as a sexual object rather than an emotional exchange with a lover, and the contents of the initial Bible experience were linked to actual sexual violence cases committed by participants. Third, childhood trauma of participants through psychodrama led to rapidly changing family circumstances and abuse by fathers. Fourth, the actual content of emotions represented by anger in the early stages of psychodrama is meaningful in that it revealed the process of sadness, pain, regret and longing for a departing mother leading to objective insight into emotions through the catharsis process.
It is important to understand the potential human health implications of exposure to environmental chemicals that may act as hormonally active agents. It is necessary to have an understanding of how pharmaceutical and personal care products and other chemicals affect the ecosystem of our planet as well as human health. Endocrine disruption is defined as the ability of a chemical contaminating the workplace or the environment to interfere with homeostasis, development, reproduction, and/or behavior in a living organism or it's offspring. Certain classes of environmentally persistent chemicals such as polychlorinated biphenyls (PCBs), dioxins, furans, and some pesticides can adversely effect the endocrine systems of aquatic life and terrestrial wildlife. Research continues to support the theory of endocrine disruption. However, endocrine disruption researches have been applied to proteomics poorly. Proteomics can be defined as the systematic analysis of proteins for their identity, quantity and function. It could increase the predictability of early drug development and identify non-invasive biomarkers of tonicity or efficacy. Proteome analysis is most commonly accomplished by the combination of two-dimensional gel electrophoresis (2D/E) and MALDI-TOF mass spectrometry (MS) sr protein chip array and SELDI-TOF MS. Proteomics have an opportunity to play an important role in resolving the question of what role endocrine disruptors play in initiating human disease. Proteomics can also play an imfortant role in the evaluation of the risk assessment and use of risk management and risk communication tools required to address public health concerns related to notions of endocrine disruptors. Understanding the need for the proteomics and possessing knowledge of the developing biomakers used to abbess endocrine activity potential will he essential components relevant to the topic of endocrine disruptors.
Protection is to maximize the protectee's physical security by minimizing the threats and minimizing the damages caused by the threats. From this point of view, the assassination case of Israel's former Premier Yitzhak Rabin who devoted himself to proceed peace process in Middle East, on November 4, 1995, gives us a lot of lessons on protection. At that time, Israeli society was chaotic with anti-Rabin and anti-government demonstrations which is against Rabin's peace process, and they openly threatened to assassinate Premier Rabin. However, Shin Bet, Israeli Protective Agency, didn't reacted against the assassination threats effectively. Also they have to try to secure friendly public to widen the width of selection in case of crisis and to secure the credibility of the organization. They have to prevent harmful activities in advance by securing wide intelligence networks to collect and analyze various protective intelligences and preparing proper protective countermeasures. Intelligence is a basic element in protection and any protective measures not supported by intelligence activities are not useful and effective. Potential attackers study their target thoroughly and make an elaborate plan before their attack. Advance team is required to conduct security measures on a basis of analysis of vulnerability and threat factors, and close protection team should be prepared for the changing situations with crisis-consciousness. Is security, 100% perfection is not possible. However, Shin Bet failed to analyze and approach to the existing threats. They forgot the fact that security environment reflects social situations. Protection agents should be conscious of the fact that today is different from yesterday. So we have to expect what is not expected when not expected.
When an accident occurs at nuclear power plant and radionuclide material is released to the area around the plant, public evacuation is considered as a measure to protect the safety of the residents nearby. This study draws factors required to estimate evacuation time and make estimation of the time to evacuate all residents from the EPZ of Wolsong site in consideration of traffic condition in the neighborhood and on the basis of field data around the site for each factor. The traffic capacity and the traffic volume by season were investigated for the traffic analysis and simulation within EPZ of Wolsong site. As a result, the background traffic volume by season were established. To estimate TGT(Trip Generation Time), the questionnaire surveys were carried out for resident and transient. The TSIS code was applied to traffic analysis in the events of daytime/night and normal/adverse weather under normal day/summer peak traffic condition. The results showed that the evacuation time required for total vehicles to move out from EPZ took generally from 118 to 150 minutes. The evacuation time took longer maximum 17 minutes at night than daytime during summer peak traffic.
A pot experiment was conducted to find out the effect of arsenic(As) added to soil on the number of roots, root diameter, root length and root tissue of the rice plant. The results obtained were as follows: Higher As levels in soil remarkably reduced not only the number of roots, root length and root diameter, but also the diameter of the central cylinder, the route of the water and inor ganic nutrients of the roots. When arsenic was treated in soil, abnormal cells in the cortex of rice root were developed and considerably increased with higher As levels in the soil. These were only observed in the middle and upper parts of root segments except root tips and they looked like rice roots without epidermis in shape. Therefore, the occurrence of the abnormal cells in the root was attributed to high arsenic accumulation in the root. Its mechanism is not clear. However, it is assumed that the abnormal cells had occurred to compensate for lower amount of water and inorganic nutrient absorption by the injured rice root or self-defense against the penetration of arsenic within the rice root.
The purpose of this study was to explore and better understand special education music teachers' perceptions of their music curriculum. For this purpose, we conducted a focus group interview with seven special education music teachers. During the interview, four major themes and 14 sub-themes were identified. The main themes were the following: (a) types of applied activities and the goals of music classes (e.g., activities to be applied in various ways depending on the characteristics of the disability and intended outcome), (b) difficulty in implementing the music curriculum (e.g., lack of fit between textbook and students' chronological ages, lack of time and focus, self-evaluation of performance as a music teacher, (c) therapeutic experiences during music classes (e.g., expectation for positive effects through music therapy, joy of witnessing changes in students, and sense of togetherness), and (d) obstacles to the therapeutic approach of music classes and need for support (e.g., lack of professional knowledge regarding therapeutic approaches and problems with administrators and school environment). Based on these results, problems in implementing the music therapy approach as part of the music curriculum in special education schools are discussed and practical solutions for educators are offered.
For over two years, after COVID-19 was first reported in the last quarter of 2019, the world has suffered from the pandemic. The Korean government has taken an initiative and has implemented a variety of policies to protect people from COVID-19. These policies have resulted in some suffering and inconvenience for people. In this context, we aim to find out what factors influence Korean college students' intention to social distance. We surveyed with Google's online survey tool(Google Form) for 116 Korean college students using a convenient sampling from December 30, 2020, to January 8, 2021. We put perceived susceptibility, perceived severity, perceived health status, level of involvement, and trust in the policy as independent variables into a multiple regression equation using the stepwise method. We found that intention to social distance was predicted by perceived susceptibility, level of involvement, and trust in the policy in the final model. The findings mean that the more people perceive themselves susceptible to COVID-19, and the more they get involved with COVID-19, and the more they trust their governmental policies on COVID-19, the more they agree on social distancing.
E171, a mixture of titanium dioxide, has been widely used as a food additive due to its whitening effect and low toxicity. However, it has been proven that E171 is no longer safe for public health. So far, there are insufficient studies on the toxic effects of E171 on organisms especially using standardized test methods. In this study, toxicity assessments of E171 to two aquatic species, water flea (Daphnia magna) and zebrafish (Danio rerio), were performed using modified standardized test methods based on the physicochemical properties of E171. The hydrodynamic diameter, polydispersity index, and turbiscan stability index (TSI) were measured to ensure the dispersion stability of E171 in exposure media during the test period. The EC50 for immobilization of water flea was 141.7 mg L-1 while zebrafish was not affected until 100 mg L-1 of E171. Measurements of reactive oxygen species (ROS) and antioxidant enzyme activities confirmed that E171 induced oxidative stress, leading to the activation of superoxide dismutase and catalase in both water flea and zebrafish, although the expression of antioxidant enzyme genes differed between species. These results suggested the potential risk of E171 to aquatic organisms and provided toxicological insights into the impacts of E171 on the environment.
This research investigates the effect of brand-self identification on brand attachment and brand commitment focusing on luxury brand. Another purpose of this study is to examine how the relationships among brand identification, brand attachment and brand committment are moderated by consumers' regulatory focus. Structural Equation Modeling using 214 questionnaires was conducted to test hypothesized model. The results reveal that perceived luxury brand personality including excitement, competence, and sophistication influences brand-self identification positively, which in turn has a signifiant positive effect on the brand attachment. It is also found that consumers' emotional attachment to luxury brands has a positive influence on the luxury brand commitment while the effect of the brand-self identification on the brand commitment is not signifiant. This finding strongly supports that brand attachment and brand commitment are distinct construct, which confirms the results of the previous studies. In addition, the results show that consumers-luxury brands relationships are moderated by consumers' regulatory focus. This finding explains that prevention-focused individuals who have interdependent self-view respond to the loss caused by relationship break more sensitively compared to the promotion-focused consumers. Finally, based on the findings of this study, theoretical contribution and managerial implications are discussed.
