This paper examines the behaviour of two types of practical open beam-to-tubular column connection details subjected to combined moment, axial and/or shear loads. Detailed continuum finite element models are developed and validated against available experimental results, and extended to deal with flexural, axial and shear load interactions. A numerical investigation is then carried out on the behaviour of selected connections with different stiffness and strength characteristics under various load combination scenarios. The influence of applied levels of axial tensile or compressive loads on the bending stiffness and capacity is examined and discussed. Additionally, the interaction effects between shear forces and co-existing bending and axial loads are examined and shown to be comparatively insignificant in terms of stiffness and capacity in most cases. It is also shown that the range of connections considered in this paper can provide rotational ductility levels in excess of those required under typical design scenarios. Based on these findings, a simplified component-based representation is proposed and described, and its ability to represent the connection response under combined loading is verified using results from detailed numerical simulations.

Purpose: Competency in physical assessment is an important component of nursing practice. However, some physical assessment skills are not being utilized within the current teacher-centered, content-heavy curriculum. This study was conducted to identify the effects of student-centered, self-directed learning in the physical assessment class. Methods: An experimental study with a post-test only control group design was used to compare an intervention group that was provided self-directed learning classes and a control group that was provided traditional lecture and practice classes. Competency in physical assessment, academic self-confidence, and learning satisfaction were evaluated. Collected data were analyzed using $x^2$-test (Fisher's exact test) and independent t-test. Results: Competency in physical assessment was significantly higher in the experimental group. However, academic self-confidence and learning satisfaction were not significantly different between the groups. Conclusion: The findings in this study indicate that self-directed learning can improve nursing students competency in physical assessment and that self-directed learning is a good education method to improve nursing students' competency in physical assessment during clinical practice and perform quality patient care by making active use of physical assessment skills.

Post-translational modifications (PTMs) of proteins are essential to increase the functional diversity of the proteome. By adding chemical groups to proteins, or degrading entire proteins by phosphorylation, glycosylation, ubiquitination, neddylation, acetylation, lipidation, and proteolysis, the complexity of the proteome increases, and this then influences most biological processes. Although small RNAs are crucial regulatory elements for gene expression in most eukaryotes, PTMs of small RNA microprocessor and RNA silencing components have not been extensively investigated in plants. To date, several studies have shown that the proteolytic regulation of AGOs is important for host-pathogen interactions. DRB4 is regulated by the ubiquitin-proteasome system, and the degradation of HYL1 is modulated by a de-etiolation repressor, COP1, and an unknown cytoplasmic protease. Here, we discuss current findings on the PTMs of microprocessor and RNA silencing components in plants.

Western medicine was first introduced to Korea by Christian missionaries and then by the Japanese in the late 19th century without its historical, philosophical, cultural, social, political, and economic values being communicated. Specifically, during the Japanese colonial era, only ideologically 'degenerated' medicine was taught to Koreans and the main orthodox stream of medicine was inaccessible. Hence, Korean medical education not only focuses on basic and clinical medicine, but also inherited hierarchical discrimination and structural violence. After Korea's liberation from Japan and the Korean war, the Korean medical education system was predominantly influenced by Americans and the Western medical education system was adopted by Korea beginning in the 1980s. During this time, ethical problems arose in Korean medical society and highlighted a need for medical humanities education to address them. For Korean medical students who are notably lacking humanistic and social culture, medical humanities education should be emphasized in the curriculum. In the Fourth Industrial Revolution, human physicians may only be distinguishable from robot physicians by ethical consciousness; consequentially, the Korean government should invest more of its public funds to develop and establish a medical humanities program in medical colleges. Such an improved medical education system in Korea is expected to foster talented physicians who are also respectable people.

Hyperhidrosis is the distressing condition of abnormal sweating which affects the palm, sole and axillary region. Transthoracic endoscopic sympathectomy is recommended as the treatment of choice for hyperhidrosis, especially when the upper limbs are affected. We experienced a case of accidental cauterization of right azygos vein in a healthy 23 year old male during endoscopic transthoracic sympathectomy. We changed the single lumen endotracheal tube to a double lumen tube which made it easier to perform the explo-thoracotomy and bleeder ligation under one lung ventilation. Crystalloid and colloid solutions, and packed RBC were loaded during explo-thoracotomy. Monitoring showed the signs indicating pulmonary edema. Pulmonary arterial catheterization revealed global heart failure. The patient was transfered to ICU for intensive management for heart failure. On the 4th postoperative day, pulmonary edema and heart failure were cured; and the patient was extubated. But in the evening of the same day ST-segment elevation and Q-wave were noted on ECG monitoring. On the 13th postoperative day coronary angiography was performed. This revealed left apex focal hypokinesia, patent coronary artery and accidental right coronary spasm, treated by vasodilator. On the 14 day, after surgery, he was discharged to return to work.

Purpose: The purpose of the study was to identify the relationship between low back pain and job stress in hospital nurses. Method: A descriptive correlation research design was employed. The participants were 355 nurses who worked in a general hospital in W city Kangwon-do and consented to participate in this study. The Visual Analog Scale and job stress scale were used in this study. Analysis included descriptive statistics, t-test, ANOVA, and partial correlation coefficients. Results: Experience of low back pain for nurse in the past was 86.5% and in the present was 67.5% for low back pain which measured an average of 4.4 points for the level of low back pain. The mean score for job stress was relatively low(M=47.2). Job demand, organization system, job instability and conflict in relationships contributed to high stress scores, instead inappropriate compensation, job culture, and job autonomy contributed to low stress. There was a significant relationship between low back pain and job stress. Conclusion: These results suggest that further research is needed to develop programs to prevention and management of low back pain for nurses.

Purpose: The purpose of this study was to analyse the level of sexual function among breast cancer survivors as compared with that among healthy women. Method: A total of 208 women participated in this study: 103 breast cancer survivors attending self-help group and 105 community-residing healthy women in G city. A self-reported questionnaire with the Female Sexual Function Index (FSFI) was used to obtain data. Data were analyzed using the SPSS Win 14.0 $K^+$ for descriptive statistics, t-test, and two-way ANOVA. Results: The sexual function score of breast cancer survivors was significantly lower than that of healthy women, respectively $14.9{\pm}9.9$ and $20.6{\pm}11.1$ (p<0.001). The sexual function of recurrent breast cancer survivors was significantly lower than that of women without recurrence. However, there were no significant differences in the sexual function score according to the cancer stage, period since diagnosis, and types of cancer treatment modality. Conclusion: The findings indicate the importance of sex-related counseling and educational programs to improve the quality of life of breast cancer survivors.

The purpose of this study was to determine whether a relationship existed between foot type and the location of plantar callus in healthy subjects. Twenty-five healthy subjects with plantar callus were recruited for this study. Foot deformities were classified according to the operational definitions as 1) a compensated forefoot varus, 2) an uncompensated forefoot varus or forefoot valgus, or 3) a compensated rearfoot varus. The location of plantar callus was divided into two regions. Fourteen of the 19 feet with compensated forefoot varus and six of the 9 feet showed plantar callus at the second, third or fourth metatarsal head. Five of the 6 feet with uncompensated forefoot varus and twenty of the 16 feet with forefoot valgus showed plantar callus at the first or fifth metatarsal head. A significant relationship was found between foot type and location of callus (p<.01). The results support the hypothesis that certain foot types are associated with characteristic patterns of pressure distribution and callus formation. We believe diabetic patients with insensitive feet and with the types of foot deformity should be fit with foot orthoses and footwears that accommodate their respective deformity in a position as near to the subtalar joint as possible with the goal of preventing plantar ulceration.

Background: The zygoma is the most prominent portion of the face. Almost all simple zygomatic arch fractures are treated in a closed fashion with a Dingman elevator. However, the open approach should be considered for unstable zygomatic arch fractures. The coronal approach for a zygomatic arch fracture has complications. In this study, we introduce our method to reduce a special type of unstable zygomatic fracture. Methods: We retrospectively reviewed zygomatic arch view and facial bone computed tomography scans of 424 patients who visited the Wonju Severance Christian Hospital from 2007 to 2010 with zygomaticomaxillary fractures, among whom 15 patients met the inclusion criteria. Results: We used a Dingman elevator and K-wire simultaneously to manage this type of zygomatic arch fracture. Simple medial rotation force usually collapses the posterior fractured segment, and the fracture becomes unstable. Thus, the posterior fracture segment must be concurrently elevated with a Dingman elevator through Keen's approach with rotation force applied through the K-wire. All fractures were reduced without any instability using this method. Conclusion: We were able to reduce unstable and difficult zygomatic arch fractures without an open incision or any external fixation device.

Amid the Covid pandemic surge last year, customers and businesses started embracing digital transactions. Digital banking, as an answer to the cash-less-contact-less way of doing financial transactions, was highly convenient during the pandemic, especially in the Philippines. This position examines the Gen Y and Gen Z in the Philippine case and its willingness to encourage digitalization of the financial sector. This study aimed at evaluating the intention to use digital banking services using the factors (1) ease of use; (2) perceived usefulness; (3) perceived risk; (4) trust; (5) convenience. A total of 226 respondents were selected by random sampling method and linear regression was used to analyse the collected data. Analysis of the results show that the components (1) perceived ease of use; (2) perceived usefulness; (3) perceived risk; (4) trust; (5) convenience had a significant effect on intention to use digital banking while the demographics - gender, age, monthly income, and educational attainment do not have any significance on the intention to use digital banking. The relevance of the study can be used for marketing and financial strategies to increase the intention to use digital banking and to contribute to the enhancement of technology acceptance concerning digital banking.
