  • Radiation Following the 2011 Fukushima nuclear accident in Japan, public interest and anxiety about radiation safety increased, and vague anxiety about commonly exposed living radiation was generated. The Atomic Energy Safety Commission has been conducting a survey of processed products that advertise "negative ions" and "far-infrared" emissions under the Living Radiation Safety Management Act. In this study, in-depth analysis was performed from a statistical point of view using the measurement data presented in the Nuclear Safety Committee's actual survey analysis report as secondary data. As a result, there was a statistically significant difference (p<0.005) between latex and civil affairs products. There were also statistically significant differences (p<0.05) in the results of testing whether there were significant differences in the annual exposure dose between groups after categorizing 71 civil products, including radon beds, into bed, bedding, and living and other categories. The correlation analysis results also confirm that, as is commonly known, the annual doses received from processed products are associated with radon derived from U-238 and Th-232.

  • As artificial intelligence is actively studied, chatbot systems are being applied to various fields. In particular, many chatbot systems for psychological counseling have been studied that can comfort modern people. However, while most psychological counseling chatbots are studied as rule-base and deep learning-based chatbots, there are large limitations for each chatbot. To overcome the limitations of psychological counseling using such chatbots, we proposes a novel psychological counseling AI chatbot system. The proposed system consists of a GPT-2 model that generates output sentence for Korean input sentences and an Electra model that serves as sentiment analysis and anxiety cause classification, which can be provided with psychological tests and collective intelligence functions. At the same time as deep learning-based chatbots and conversations take place, sentiment analysis of input sentences simultaneously recognizes user's emotions and presents psychological tests and collective intelligence solutions to solve the limitations of psychological counseling that can only be done with chatbots. Since the role of sentiment analysis and anxiety cause classification, which are the links of each function, is important for the progression of the proposed system, we experiment the performance of those parts. We verify the novelty and accuracy of the proposed system. It also shows that the AI chatbot system can perform counseling excellently.

  • Growing evidence indicates a crucial role of the gut microbiota in physiological functions. Gut-brain axis imbalance has also been associated with neuropsychiatric and neurodegenerative disorders. Studies have suggested that probiotics regulate the stress response and alleviate mood-related symptoms. In this study, we investigated the effects of the probiotic Lacticaseibacillus rhamnosus IDCC3201 (L3201) on the behavioral response and fecal metabolite content in an unpredictable chronic mild stress (UCMS) mouse model. Our study shows that chronic stress in mice for three weeks resulted in significant changes in behavior, including lower locomotor activity, higher levels of anxiety, and depressive-like symptoms, compared to the control group. Metabolomic analysis demonstrated that disrupted fecal metabolites associated with aminoacyl-tRNA biosynthesis and valine, leucine, and isoleucine biosynthesis by UCMS were restored with the administration of L3201. Oral administration of the L3201 ameliorated the observed changes and improved the behavioral alterations along with fecal metabolites, suggesting that probiotics play a neuroprotective role.

  • Purpose : This study was to examine the secondary traumatic stress(STS) and related factors of emergency medical technicians. Methods : This study was conducted among 190 emergency medical technicians, over the age of 25, with the 1st or 2nd grade qualification, who serve at fire stations in U and P city of Korea. The collected data for this study was analyzed using SPSS 12.0. Result : The average character type of A-type personality technicians was 43.25 points and the average of B-type personality technicians was 37.82 points. It suggested that the former was higher than the latter. State anxiety did not show statistically significant difference between A-Type group and B-Type group with the score of 48.51 for A-Type and 47.91 for B-Type. Physical symptoms showed statistically significant difference between the two groups with the higher score of 28.45 for A-type group than that of 28.13 for B-Type group. The level of STS related to the volunteers' job characteristics was found to be low when the volunteers were satisfied with their job and didn't want to transfer to another division. Those on duty who had slept more than seven hours that day had the highest points. The number of points was highest when the frequency for the onset of trauma was between 20~30 times. Furthermore it was found that for most technicians, 71.05%, the period of symptoms lasted for a few weeks at most, and this was where the STS was the lowest, whereas on the other hand the highest STS occurred when the symptoms lasted for a period of up to six months. The findings showed significant correlations with a relation of r=.24 between STS and level of anxiety and r=.45 between STS and physical symptoms. However, no significant correlation was found between the level of anxiety and physical symptoms. Conclusion : The more emergency medical technicians are exposed to accidents, the more serious the STS are. Those with an A-type personality are especially prone to have higher STS. The higher the STS level is, the higher the level of physical states and anxiety is.

  • Introduction: Breast cancer is the most common cancer among Jordanians. Breast cancer patients suffer from several negative consequences after treatment and these include pain, fatigue, sexual problems, appearance and body image concerns, with psychological dysfunction. This could affect the patient quality of life and psychological well-being. To the best of our knowledge, there is no published quantitative data on the quality of life and psychological well-being of breast cancer patients in Jordan. The objective of this study was to obtain such data and assess predictors with calculated scores. Methods: In this cross-sectional study conducted among breast cancer patients in Jordan diagnosed in 2009 and 2010, assessment was performed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), the Breast Module (QLQ-BR23) and the Hospital Anxiety and Depression Scale (HADS). Clinical, demographic and psychosocial indicators that could predict patient quality of life scores were collected. Results: The number of patients interviewed was 236 (mean age=$50.7{\pm}10.7$ years). The mean Global Health score for the QLQ-C30 was $63.7{\pm}20.2$ SD. Among functional scales, "social functioning" scored the highest ($mean=78.1{\pm}28.6$ SD), whereas "emotional functioning" scored the lowest ($mean=59.0{\pm}SD\;33.5$). For the QLQ-BR23, the worst scores within the functional scales were for "body image" ($mean=52.1{\pm}36.8$ SD) and "future perspective" ($mean=52.9{\pm}38.5$ SD). The worst symptom was "upset by hair loss" ($mean=69.8{\pm}43.0$). The mean HADS scores was $18.{\pm}9.0$ SD. Out of study participants, 53% scored abnormal on the anxiety scale and 45% on the depression scale. Severe depression and severe anxiety were detected among 8% and 14% of study participants, respectively. Statistically significant predictors for individual scores were similar to those reported in published studies, such as the presence of recurrence since baseline, family history of cancer, low educational status, current social problems, extent of the disease, presence of financial difficulties, and employment status. Conclusions and Recommendations: Breast cancer survivors in Jordan have overall good quality of life scores when compared with patients from Western countries. However, their psychological wellbeing is more impaired. There is an urgent need for psychosocial support programs and psychological screening and consultation for breast cancer patients at hospitals of the Ministry of Health in Jordan.

  • 현대를 살아가는 우리는 대형마트와 아웃렛을 쉽게 접할 수 있고 편리한 모바일 쇼핑과 당일·새벽배송시대를 살고 있다. 이러한 쇼핑의 목적이 재화 본연의 목적에 기인하지 않고 스스로 조절할 수 없는 충동에 의해 구매하는 상태에 이르는 것을 '쇼핑중독' 이라고 한다. 과거 연구에 따르면 미국 성인의 5.8%, 한국 여대생의 15.5%가 구매중독으로 조사[3]되었다. 이 연구는 소비자가 구매중독에 이르는 다양한 요인 중 대인 불안, 타인 의식성, 자기 통제력과의 관계를 파악하여 소비자의 내적 심리에 미치는 영향에 관하여 확인하였다. 연구결과 대인 불안은 구매중독에 직접적인 영향을 미치지 않았으나 자기 통제력과 타인 의식성에 영향을 받아 구매중독 성향을 높이는 것으로 나타났다. 남녀 집단비교 결과 남성은 자기 통제력, 여성은 타인 의식성에 의해 구매중독 성향이 높아지는 것을 확인할 수 있었다. 이러한 남녀 심리의 차이에 따라 구매중독 예방관리와 치료방식을 달리 적용해야 하는 등 관련 시사점을 제시하였다.

  • Despite the existing body of literature focusing on the effects of one-to-one mobile technology integration in teaching and learning, research discussed that the determinants of mobile technology acceptance and use in secondary school settings are still unclear. Hence, this study examined the extent to which determinants influence high school students' behavioral intention to use one-to-one mobile technology for learning. The newly proposed model incorporated three additional constructs beyond those in the unified theory of acceptance and use of technology (UTAUT) model, including computer self-efficacy, attitude toward using technology and computer anxiety, as suggested by recent literature. Data were collected from 247 U.S. Midwestern high school students who participated in an online survey. Using a structural equation modeling approach, this study established construct validity for the nine-construct extended UTAUT model to assess high school students' intention to use mobile technology. The results of structural relations in the proposed model showed that their behavioral intention to use mobile technology was significantly predicted by social influence and attitude toward using technology. Also, their strong behavioral intention and facilitating conditions were associated with frequent use of mobile technology in learning. Discussion, implications, and conclusion were addressed in this study.
