Describing Gambling Affinity: The Role of Personality Traits

This study was undertaken to determine the degree to which personality dimensions provide insights into who is likely to gamble a significant dollar amount at a casino. Using measures of the Big Five, respondents were grouped into one of the following four personality clusters: (a) Moderate Trait Scores, in which no trait dimension was dominant; (b) Elevated Trait Scores, where a respondent scored highly across trait dimensions; (c) Agreeably Conscientious, in which a respondent scored highly on the agreeableness and conscientious trait domains; and (d) Highly Extraverted, where a respondent’s dominant trait dimension was extraversion. Respondents who were classified as Highly Extraverted were the most likely to gamble a day’s wages at a casino. Those classified into the Moderate Trait Scores cluster also exhibited a gambling affinity. Other factors associated with gambling affinity included subjective financial knowledge, financial satisfaction, and risk tolerance. Results from this study show that personality traits are important descriptors of gambling affinity; however, rather than there being a direct relationship with individual trait factors, the willingness to gamble appears to be based on unique combinations of personality. Findings from this study provide direct insights into who is more likely to require financial advice regarding gambling expenditures at the household level

Sonographic measurements of normal gallbladder sizes in children.

PurposeOur goal was to establish the range of sonographic measurements of normal gallbladders in children.MethodsSix hundred ten children aged 0-16 years (male:female ratio, 1.5:1) with normal clinical and laboratory findings were included in this study. The sonographic parameters were the length, width, and calculated volume of the gallbladder, and the clinical parameters were the age, height, weight, and body surface area of the children. Statistical significance was determined through correlation and regression analyses.ResultsThe length of the gallbladder showed significant positive correlations with age (r = 0.65), height (r = 0.67), weight (r = 0.63), and body surface area (r = 0.65; p < 0.01). The calculated volume of the gallbladder also showed moderate correlations with age (r = 0.53), height (r = 0.55), weight (r = 0.61), and body surface area (r = 0.57; p < 0.01). The gallbladder width showed modest but significant correlations with age (r = 0.48), height (r = 0.53), weight (r = 0.53), and body surface area (r = 0.55; p < 0.01). The highest correlation coefficients were found between the gallbladder length and subject age (r = 0.65; p < 0.01) and between the gallbladder length and subject height (r = 0.67; p < 0.01). For all correlations, statistical significance remained after regression analysis (p < 0.01).ConclusionsValues for the size of the normal pediatric gallbladder are defined and will be helpful in the diagnosis of gallbladder abnormalities

Interrupted aortic arch diagnosed with loss of femoral pulse in a patient undergoing patent ductus arteriosus ligation -A case report-

A 12-year-old boy with ventricular septal defect and patent ductus arteriosus was presented to the operating room. Upon clamping the patent ductus arteriosus, the femoral arterial pressure curve was lost; however, it returned upon unclamping. Upon further dissection, an interrupted aortic arch was found between the left subclavian artery and patent ductus arteriosus. The surgery was discontinued for further evaluation

A Phenomenological Study on the Experiences of Parenting Burden of Working Mother with Young Children in Korea

PURPOSE: The purpose of this study was to describe the essential structure of the lived experience of working mothers' parenting burden in Korea. METHODS: Eight working mothers with young children were interviewed. The Colaizzi analysis of phenomenological research was applied. RESULTS: Seven theme clusters were extracted: a life with constant conflict, sense of guilt, feeling anxious because of lack of information about education for their children, social stigma as a deficient mother, family relationship becoming distant, a life being exhausted, day to day struggle. CONCLUSION: These results provide an opportunity to have a better understanding of the experiences of working mothers related to parenting their young children. It would also serve as a medium for the formulation of appropriate nursing intervention relevant to burdens of parenthood

Analysis On Runoff Characteristics Of Decentralized Rainwater Management System Using XP-SWMM Simulation

In recent years, impervious areas are increasing in residential zone as well as unsettled area with rapid urbanization and land use. Consequently, this phenomenon influences weak urban environmental compositions about climate change including urban flooding accidents. Therefore, a new paradigm on rainwater management is needed for sound and sustainable restoration of hydrological circulation. Recently, a novel rainwater management system has been developed and recommended for irrigation and flood control in Korea. Especially, P city is now planning a new rainwater management system adopting LID (Low Impact Development) techniques on a small scale development area. In this study, XP-SWMM was used to simulate effects on runoff characteristics by installation of 8 kinds of rainwater management facilities on small scale development area (4.2 ha) of P city in Korea. Also, flood control safety analysis under the condition of localized torrential downpour event was carried out and effects of rainwater recycling facility was evaluated to measure annual water resource amount and water cost reduction. Peak rate runoff was reduced 11.8% and 36.4% in restrict A and B, respectively. Total amount of annual water source substitution was estimated 3,000㎡/yr with LID adoption in land use planning.

Chronic Idiopathic Myelofibrosis Presenting as Cauda Equina Compression due to Extramedullary Hematopoiesis: A Case Report

Extramedullary hematopoiesis (EMH) is occasionally reported in idiopathic myelofibrosis and is generally found in the liver, spleen, and lymph nodes several years after diagnosis. Myelofibrosis presenting as spinal cord compression, resulting from EMH tissue is very rare. A 39-yr-old man presented with back pain, subjective weakness and numbness in both legs. Sagittal magnetic resonance imaging showed multiple anterior epidural mass extending from L4 to S1 with compression of cauda equina and nerve root. The patient underwent gross total removal of the mass via L4, 5, and S1 laminectomy. Histological analysis showed islands of myelopoietic cells surrounded by fatty tissue, consistent with EMH, and bone marrow biopsy performed after surgery revealed hypercellular marrow and megakaryocytic hyperplasia and focal fibrosis. The final diagnosis was chronic idiopathic myelofibrosis leading to EMH in the lumbar spinal canal. Since there were no abnormal hematological findings except mild myelofibrosis, additional treatment such as radiothepary was not administered postoperatively for fear of radiotoxicity. On 6 month follow-up examination, the patient remained clinically stable without recurrence. This is the first case of chronic idiopathic myelofibrosis due to EMH tissue in the lumbar spinal canal in Korea

Breathing silicon anodes for durable high-power operations

Silicon anode materials have been developed to achieve high capacity lithium ion batteries for operating smart phones and driving electric vehicles for longer time. Serious volume expansion induced by lithiation, which is the main drawback of silicon, has been challenged by multi-faceted approaches. Mechanically rigid and stiff polymers (e.g. alginate and carboxymethyl cellulose) were considered as the good choices of binders for silicon because they grab silicon particles in a tight and rigid way so that pulverization and then break-away of the active mass from electric pathways are suppressed. Contrary to the public wisdom, in this work, we demonstrate that electrochemical performances are secured better by letting silicon electrodes breathe in and out lithium ions with volume change rather than by fixing their dimensions. The breathing electrodes were achieved by using a polysaccharide (pullulan), the conformation of which is modulated from chair to boat during elongation. The conformational transition of pullulan was originated from its a glycosidic linkages while the conventional rigid polysaccharide binders have beta linkagesopen1
