Many patients of acute myocardial infarction showed delay time before seeking treatment although they needed immediate thrombolytic therapy once they perceived their symptoms. The objectives of this study were to identify the relationship between clinical symptoms and the delay, and to find the time spent before seeking the treatment. This study was a retrospective research. The delay time for the treatment consisted of the length of delay from symptom onset to patients' decision (T1), from patients' decision making to finding transportation (T2), and from taking transportation to the first hospital arrival(T3). The subjects were 89 patients who were admitted in the ICU and Cardiac Ward at Chonnam University Hospital with the first attack of acute myocardial infarction. The data was collected for three months from March 1st to May 31st of 1998 through questionnaires and reviewing patients' charts: The chart information was suppled by two nurses working at the ICU and Cardiac Ward. The data was analyzed by using frequency, mean and ANOVA through the SAS program. The results of study summarized as follows: 1. Sixty two patients (69.7%) were male and twenty seven patients (30.3%) were female, the ratio of male to female was 2.3 : 1. 2. In daily life, the 70.8% of the patients felt chest pain and discomfort fatigue in 67.4%, dyspnea in 57.3%, and pain in arm, neck, and jaw in 52.8%. During the attack, 97.8% of the patients felt chest pain and discomfort dyspnea in 82.1%, pain in arm, neck, jaw in 67.4% and perspiration in 51.7%. 3. The length of time a patient spent seeking time for treatment (T1+T2+T3) was 94.6 minutes, in which the time for patients' decision making for treatment (T1) was 70.3 minutes, time for finding transportation (T2) was 8.2 minutes, and time for the transportation of the patient to the first hospital (T3) was 16.1 minutes. Time for patients' decision making to go to a hospital(T1) was 74.2% of the total time sought for treatment.

PURPOSE: The purpose of this study was to identify the impacts of job stress and job embeddedness on presenteeism among container terminal workers. METHODS: The participants were 299 workers at the S Harbor in P City. Data were collected from April 22 to June 5, 2015. The data were analyzed using t-test, ANOVA, Scheffé's test, Pearson's correlation coefficients, and logistic regression. RESULTS: These workers on presenteeism were affected by the department of work, annual pay, and exercise of more than 30 minutes per day, revealing a statistically significant difference according to these variables. In other words, when job stress was high, job embeddedness was less, the extent of work impairment was higher, and in turn perceived productivity was lower. Work impairment was 3.11 times higher in workers with above-average job stress than those with lower job stress. Perceived productivity was 2.31 times higher in workers with above-average job embeddedness than those with lower job embeddedness. CONCLUSION: To reduce work impairment and increase productivity among container terminal workers, it is necessary to decrease their job stress, to increase their job embeddedness, and especially to do exercise for more than 30 minutes a day.

PURPOSE: There is a fair amount of evidence indicating that increased risk of obesity and insulin resistance is associated with postmenopausal state, but can be modulated by diet and exercise. In this study, we explored whether a Pueraria lobata root-based supplement containing Rehmannia glutinosa (PR) and/or aerobic treadmill exercise can modify the metabolic changes associated with estrogen deficiency. METHODS: Seventy rats were randomly assigned to the following groups for 8 weeks (n=10 per group): SHAM, sham-operated; PR0, ovariectomized (OVX) control; PR200, OVX with PR200 mg/kg B.W; PR400, OVX with PR400 mg/kg B.W; EPR0, OVX with exercise; EPR200, OVX with exercise and PR200 mg/kg B.W; EPR400, OVX with exercise and PR400 mg/kg B.W. RESULTS: OVX induced significant increases in body weight, food intake, fat mass, LDL-cholesterol, and fasting blood glucose, confirming induction of menopausal symptoms. PR supplementation or exercise significantly suppressed the above mentioned changes through different regulatory elements in adipose tissue: PR supplement upregulated adiponectin gene expression and aerobic exercise upregulated adiponectin and insulin receptor gene expression and a combination of PR supplement and aerobic exercise showed an additive effect on adiponectin gene expression. CONCLUSION: Taken together, the results of this study suggest that PR supplement has a potential to provide health benefits in OVX rats through leptin and adiponectin secretion. In addition, the data suggest that combination of exercise and PR would have additive effects on metabolic dysfunction associated with estrogen deficiency.

PURPOSE: This study was conducted to identify the factors affecting container terminal worker's recovery experience from job stress. METHODS: The subjects were 299 workers from one S dock in P city. Data were collected from April 5 to June 5, 2015 and analyzed by SPSS/WIN 18.0 program using descriptive statistics, t-test, ANOVA, Sheffe test, Pearson's correlation coefficients, and logistic regression. RESULTS: The mean scores of job stress, ego-resilience, and recovery experience from job stress were 47.18, 46.90, and 49.17 respectively. Recovery experience according to the general characteristics showed significant correlation between daily exercise. There was a significant negative correlation between recovery experience and job stress, and a positive correlation between recovery experience and ego-resilience. Recovery experience was 2.54 times higher for a high ego-resilience group than for a low ego-resilience group, and the group that exercised was 2.25 times higher, than the non-exercising group. The group with a low level of interpersonal conflict was 1.97 times higher, than a group with a high level of interpersonal conflict. CONCLUSION: Based on this study, intervention programs to increase ego-resilience, decrease interpersonal conflict, and encourage over 30-minute-daily exercise for in container terminal workers should be developed to improve recovery experience of job stress.

Cardiac organoids have emerged as invaluable tools for assessing the impact of diverse substances on heart function.This report introduces guidelines for general requirements for manufacturing cardiac organoids and conducting cardiac organoid-based assays, encompassing protocols, analytical methodologies, and ethical considerations. In the quest to employ recently developed three-dimensional cardiac organoid models as substitutes for animal testing, it becomes imperative to establish robust criteria for evaluating organoid quality and conducting toxicity assessments. This guideline addresses this need, catering to regulatory requirements, and describes common standards for organoid quality and toxicity assessment methodologies, commensurate with current technological capabilities. While acknowledging the dynamic nature of technological progress and the potential for future comparative studies, this guideline serves as a foundational framework. It offers a comprehensive approach to standardized cardiac organoid testing, ensuring scientific rigor, reproducibility, and ethical integrity in investigations of cardiotoxicity, particularly through the utilization of human pluripotent stem cell-derived cardiac organoids.

BACKGROUND AND OBJECTIVES: Pulmonary embolism (PE) is a disease with high mortality if left untreated. But, confirmative diagnosis is difficult because many diagnostic modalities are nonspecific. Pulmonary angiography, which is considered as the gold standard diagnostic tool, is invasive, costly, time-consuming, and not always available in small centers. Echocardiography is a non-invasive and available in the emergency room without significant time delay. We investigated the role of echocardiography as a screening test in patients with suspected PE. MATERIALS AND METHODS: (A) Retrospective study: We analyzed the recorded videotapes of transthoracic echocardiography in fifty patients with confirmed PE from Jan 1995 to Aug 1999. From the frequent echocardiographic findings of those patients, positive criteria were defined as followed ( 2 among 1-5 or only 6). (1) RV or pulmonary artery dilatation (RVEDA/LVEDA 0.6) (2) RV hypokinesis (3) paradoxical septal wall motion (4) pulmonary hypertension (5) TR (moderate degree or more) (6) Visible thrombus. Although the degree of TR was less than moderate, if the degree of pulmonary hypertension was more than moderate, we considered as PE. (B) Prospective study: From Nov 1999 to June 2000, patients with suspected pulmonary embolism underwent a transthoracic echocardiography and perfusion-ventilation lung scan or chest CT. We assessed echocardiographic findings, sensitivity and specificity of the previously defined echocardiographic positive criteria for PE. RESULTS: (A) Retrospective study: The sensitivity of echocardiography for PE was 74%. (B) Prospective study: The number of enrolled patients was thirty-four. In twenty patients the diagnosis was PE. The sensitivity of echocardiography was 75% but the specificity was 14%. CONCLUSION: Echocardiography may be used as a good screening test in patients who are clinically suspicious of pulmonary embolism.

PURPOSE: The purpose of this study was to examine nurses' sexual health care attitude and practice while caring for cancer patients. METHODS: Data were collected using a structured questionnaire from 236 nurses caring for patients with cancer from June 30, 2014 to July 6, 2014 at a University Hospital in Daegu, Korea. RESULTS: The mean score for sexual health care attitude of nurses caring for patients with cancer was 27.75+/-6.45 of a possible range 17 to 51 and the mean score for a sexual health care practice of nurses was 3.67+/-3.30 of a possible range 0 to 21. The scores of a sexual health care attitude and practice were significantly different by age, education, department, experience in gynecology or urology departments, and position. Sexual health care attitude and practice had a significantly positive correlation (r=.16, p=.015). CONCLUSION: The nurses caring for patients with cancer recognize the importance of sexual health care, but their sexual health care practice rate was very low. Therefore specific and differentiated nurse education programs designed to increase sexual health care practice are required for young nurses and staff nurses that are not practicing sexual health care often.
