  • Purpose: This study aimed to examine the effects of a mobile navigation program on uncertainty, resilience, and growth through uncertainty in colorectal cancer patients. Methods: To verify the effectiveness of the mobile navigation program, 61 participants diagnosed with colorectal cancer undergoing surgery were selected. A nonequivalent control group nonsynchronized design was used to evaluate the program. Uncertainty was measured using the Korean version of the Uncertainty in Illness Scale, resilience was measured using the Korean version of the Connor-Davidson Resilience Scale, and growth through uncertainty was measured using the Growth through Uncertainty Scale. Results: Compared with the control group, patients in the mobile navigation program group showed significant differences in scores for uncertainty (F=7.22, p=.009) and resilience (F=4.31, p=.042), but not for growth through uncertainty (F=2.76, p=.102). Conclusion: These results suggest that the mobile navigation program has positive effects on decreasing uncertainty and increasing resilience among colorectal cancer patients. The mobile navigation program could play a significant role in assisting colorectal cancer patients in regard to the continuity and usability of the program.

  • Open Science is an umbrella term that involves various movements aiming to remove the barriers to sharing any kind of output, resources, methods or tools at any stage of the research process. While the study of open science is relatively advanced in Western countries, we know of no scholarship that attempts to understand open science in Hong Kong. This paper provides a broad-based background on the major research data management organisations, policies and institutions with the intention of laying a foundation for more rigorous future research that quantifies the benefits of open access and open data policies. We explore the status and prospects for open science (open access and open data) in the context of Hong Kong and how open science can contribute to innovation in Hong Kong. Surveying Hong Kong's policies and players, we identify both lost research potential and provide positive examples of Hong Kong's contribution to scientific research. Finally, we offer suggestions regarding what changes can be made to address the gaps we identify.

  • Purpose: This study aimed to develop and test a model for posttraumatic growth among cured patients with COVID-19. This model was based on Calhoun and Tedeschi's Posttraumatic Growth model and a literature review. Methods: The participants comprised 223 patients cured from COVID-19 who were ≥ 19 years of age. The data were collected through an online questionnaire from March 21 to 24, 2022. The assessment tools included the Impact of Event Scale: Revised Korean version, the Connor-Davidson Resilience Scale, the Distress Disclosure Index, the Multidimensional Scale of Perceived Social Support, the Korean version of the Event-related Rumination Inventory, and the Korean version of the Post-traumatic Growth Inventory. Data were analyzed using the IBM SPSS version 24.0 and IBM AMOS 26.0. Results: The modified model showed appropriate goodness of fit (χ2 = 369.90, χ2 /degree of freedom = 2.09, SRMR = .09, RMESA = .07, CFI = .94, TLI = .93). The post-traumatic growth of cured patients with COVID-19 was explained through distress perception, self-disclosure, and deliberate rumination, with the explanatory power being 70.0%. Conclusion: This study suggests preparing a disaster psychology program involving experts who can activate deliberate rumination is necessary. Further, this study may serve as basic data for developing a program to enhance the post-traumatic growth of patients cured from COVID-19.

  • Many materials including cementitious concrete-type materials undergo material property changes during high-rate loading. There is a wealth of research regarding this phenomenon for concrete in compression and tension. However, there is minimal knowledge about how mortar material used in concrete masonry unit (CMU) construction behaves in high-rate shear loading. A series of experiments was conducted to examine the bond strength of mortar bonded to CMU units under high-rate shear loading. A novel experimental setup using a shock tube and dynamic ram were used to load specially constructed shear triplets in a double lap shear configuration with no pre-compression. The Finite Element Method was leveraged in conjunction with data from the experimental investigation to establish if the shear bond between concrete masonry units and mortar exhibits any rate dependency. An increase in shear bond strength was observed when loaded at a high strain rate. This data indicates that the CMU-mortar bond exhibits a rate dependent strength change and illustrates the need for further study of the CMU-mortar interface characteristics at high strain rates.

  • Objectives The purpose of this study was to examine the differences according to depressive symptom-related difficulty status. Methods 2828 participants were a divided into depressive symptom-related difficulty group (difficult group, n = 774), and a non-depressive symptom-related difficulty group (not difficult group, n = 2054). The psychological character of the participants were assessed using the Korean version of the Patient Health Questionnaire-9 (PHQ-9), Satisfaction with Life Scale (SWLS), the 12-item General Health Questionnaire (GHQ-12), and Conner-Davidson Resilience Scale (CD-RISC). Statistical analyses were done using t-test, chi-square, and analysis of covariance (ANCOVA). Results Compared with the no difficulty group, the difficulty group reported significantly higher score in all items of PHQ-9. The score of "feeling tired" was the highest and the score of "suicidal ideation" is the lowest in both groups. ANCOVA analysis that is adjusted with the total score of PHQ-9 showed the differences in SWLS, GHQ-12, and CD-RISC scores between the difficulty group and the no difficulty group. Conclusions The findings suggest that there are different characters on PHQ-9, SWLS, GHQ-12, and CD-RISC according to depressive symptom-related difficulty. Therefore, it is required not only to evaluate depressive symptoms in patients with depression, but also the depressive symptom-related difficulty to understand these differences.

  • Rodents are well-known reservoirs and vectors of many emerging and re-emerging infectious diseases, but little is known about their role in zoonotic disease transmission in Bhutan. In this study, a cross-sectional investigation of zoonotic disease pathogens in rodents was performed in Chukha district, Bhutan, where a high incidence of scrub typhus and cases of acute undifferentiated febrile illness had been reported in people during the preceding 4-6 months. Twelve rodents were trapped alive using wire-mesh traps. Following euthanasia, liver and kidney tissues were removed and tested using PCR for Orientia tsutsugamushi and other bacterial and rickettsial pathogens causing bartonellosis, borreliosis, human monocytic ehrlichiosis, human granulocytic anaplasmosis, leptospirosis, and rickettsiosis. A phylogenetic analysis was performed on all rodent species captured and pathogens detected. Four out of the 12 rodents (33.3%) tested positive by PCR for zoonotic pathogens. Anaplasma phagocytophilum, Bartonella grahamii, and B. queenslandensis were identified for the first time in Bhutan. Leptospira interrogans was also detected for the first time from rodents in Bhutan. The findings demonstrate the presence of these zoonotic pathogens in rodents in Bhutan, which may pose a risk of disease transmission to humans.

  • The few lignin biomarker studies conducted in tropical environments are hampered by having to use references signatures established for plants and soils characteristic of the temperate zone. This study presents a lignin biomarker analysis (vanillyls (V), p-hydroxyls (P), syringyls (S), cinnamyls (C)) of the dominant plant species and soil horizons as well as an analysis of the interrelated terrigenous organic matter (TOM) dynamics between vegetation and soil of the $Tapaj{\acute{o}}s$ river region, an active colonization front in the Brazilian Amazon. We collected and analyzed samples from 17 fresh dominant plant species and 48 soil cores at three depths (0-5 cm, 20-25 cm, 50-55 cm) from primary rainforest, fallow forest, subsistence agriculture fields and pastures. Lignin signatures in tropical plants clearly distinguish from temperate ones with high ratios of Acid/aldehyde of vanillyls ((Ad/Al)v) and P/V+S. Contrary to temperate environments, similarly high ratios in tropical soils are not related to TOM degradation along with pedogenesis but to direct influence of plants growing on them. Lignin signatures of both plants and soils of primary rainforest and fallow forest clearly distinguish from those of non-forested areas, i.e., agriculture fields and pastures. Attalea speciosa Palm trees, an invasive species in all perturbed landscapes of the Amazon, exhibit lignin signatures clearly distinct from other dominant plant species. The study of lignin signatures in tropical areas thus represents a powerful tool to evaluate the impact of primary rainforest clearing on TOM dynamics in tropical areas.

  • Objectives : Since prostitution is multitraumatic phenomena, it is known that most women in prostitution have symptoms of posttraumatic stress disorder (PTSD) and other mental illness. In Korea, new anti-prostitution law launched in the year of 2004 imposes protecting prostituted victims at government-supported shelter. The objective of this study was to compare the mental symptoms, especially PTSD features of women who escaped from prostitution with those of control subjects. Methods : We assessed 113 ex-prostituted women who live in shelter for 8 months on the average and 65 normal control subjects. Demographic data, questionnaire for sleep, physical illness, smoking, alcohol and drug use, Stress Response Inventory, Davidson Trauma Scale (DTS), Impact of Event Scale-Revised (IES-R) were used. Results : Ex-prostituted women had significantly higher scores of DTS, IES-R, stress related responses, sleep problems, smoking problems, and alcohol problems than control group. Age and duration of sex trade of the subjects were significantly correlated with the severity or frequency of PTSD symptoms. The degree of smoking, alcohol drinking and sleep problems were also significantly correlated with the PTSD symptoms. Conclusion : These results suggested mental symptoms did not disappear even after women escaped from prostitution.

  • Objective : This study aimed to ascertain the effect of interpersonal sensitivity/resilience on depression and anxiety in firefighters whose frequency of exposure to traumatic events is high. Method : A survey was performed and data related to 75 firefighters were analyzed. Questionnaires included the Beck Depression Inventory (BDI) and Impact of Event Scale-Revised (IES-R). To assess the susceptibility or protector roles with respect to psychopathology, the Interpersonal Sensitivity Measure (IPSM) and Conner-Davidson Resilience Scale (CD-RISC) were used. Results : The personality characteristic, interpersonal sensitivity (IPSM) showed a significant positive correlation with depression (BDI, r=0.557, p<0.001) and posttraumatic stress symptoms (IES-R, r=0.316 ; p<0.001). In contrast, resilience and symptom parameters (BDI, IES-R) were negatively correlated with each other, but not statistically significant. However, an adaptive factor for change, a third sub-factor of CD-RISC, had significant negative correlation with depression and anxiety symptoms (BDI, r=-0.275, p<0.005 ; IES-R, r=-0.254, p<0.005). Conclusion : The results of the present study showed that some personality traits may act as vulnerability or protective factors with respect to the psychopathologies of depression and anxiety.

  • Background: The majority of deaths from cancer occur in low and middle income countries, partly due to poor public awareness of the signs and symptoms of cancer. Materials and Methods: A community based survey using the Cancer Awareness Measure (CAM) questionnaire was conducted in three different communities in Oman. Omani adults aged 18 years and above were invited to participate in the study. Results: A total of 345 responded from 450 invited participants (response rate=76.7%). The majority of respondents were unable to identify the common signs and symptoms of cancer identified in the CAM (average awareness was 40.6%). The most emotional barrier to seeking help was worry about what the doctor might find (223, 64.6%); a practical barrier was too busy to make an appointment (259, 75.1%) and a service barrier was difficulty talking to the doctor (159, 46.1%). The majority of respondents (more than 60% for seven out of ten symptoms) would seek medical help in two weeks for most signs or symptoms of cancer. Females were significantly more likely than males to be embarrassed (p<0.001), scared (p=0.001), and lack confidence talking about their symptoms (p=0.022). Conclusions: Urgent strategies are needed to improve public awareness of the signs and symptoms of cancer in Oman. This might leads to earlier diagnosis, improved prognosis and reduced mortality from cancer.
