Objectives: The object of this study is to assess the relationship between socioeconomic factors and the predicted 10-year risk of cardiovascular disease by using health risk appraisal of ischemic heart disease. Methods: The study population was taken from The 2001 Korea National Health and Nutrition Survey, and it consisted of 1,566 men and 1,984 women aged 30-59. We calculated 10-year risk using the risk function of ischemic heart disease as developed by Jee. The educational level and equivalized household income were dichotomized by a 12 years education period and the median income level. Occupation was dichotomized into manual/non-manual work. We stratified the population by age(10 years) and sex, and then we rated the risk differences according to socioeconomic factors by performing t-tests for each strata. Results: There were gradients of the predicted 10-year risk of ischemic heart disease with the educational level and the equivalized household income, and thet was an increasing tendency of risk differences with age. Manual workers didn't show significant risk difference from non-manual workers. Conclusions: There was definite relationship between low socioeconomic position and the predicted risk of ischemic heart disease in the future.

EUS currently plays an important role in the diagnosis and treatment of digestive diseases. In addition, EUS-guided sampling has been applied to pancreaticobiliary lesions for the accurate diagnosis of pancreaticobiliary lesions. Many new instruments and studies for EUS-guided sampling are being developed and attempted. This review introduces and summarizes the key recommendations made in the recent guideline for EUS-guided sampling developed by the European Society of Gastrointestinal Endoscopy.

Acute pancreatitis is a common gastrointestinal disease that is associated with significant morbidity and consumes enormous health care resources. As such, it requires up-to-date evidence-based diagnosis and standard treatment guidelines with broad support from the clinician. Korean Pancreatobiliary Association has developed clinical practice guidelines for the diagnosis and treatment of acute pancreatitis to provide a framework for clinicians to manage acute pancreatitis and to improve national health care. The guidelines were divided into four parts: the diagnosis of acute pancreatitis, the assessment of the severity, the initial management, and the treatment of necrotizing pancreatitis and local complications of acute pancreatitis. In this article, we summarize and present the diagnosis and treatment guidelines for acute pancreatitis established in Korea. (Korean J Gastroenterol 2018;72:281-285)

Objectives: Occupational low back pain is a major cause of morbidity and the increases of medical and industrial costs. Efforts to control occupational low back pain have been largely unsuccessful, and further understanding of the risks including the psychological factors is needed. This retrospective study was designed to identify the effect of job stress on occupational low back pain among shipyard workers. Methods: The study group consisted of 976 male workers who were working at a Korean shipyard. A structured self-reported questionnaire was used to assess the participants' physical work factors, job stress and general characteristics. Job stress was measured using Karasek's JCQ(Job Content Questionnaire). Occupational low back pain was identified according to the NIOSH symptom survey criteria. Physical work factors were assessed using the Quick Exposure Check. Since the work duration can affect the relationship of physical work factors and job stress to occupational low back pain, we analyzed this association by dividing workers into two groups by work duration: 1) all workers, and 2) less than 5 years. Cox's proportional hazard model was used to elucidate the relationship of job stress with occupational low back pain in these two groups. Data were analysed with SAS 8.1. Results: In the all workers group, job demand, bending or twisting of the back, and carrying heavy materials were associated with an increased the risk of occupational low back pain. In the workers with less than 5 years work experience, people with high job demand were more likely to experience occupational low back pain than those with low job demand. Conclusions: These results suggest that job stress as well as physical work factors can raise the risk of occupational low back pain. Especially, in the workers with less than 5 years work duration, job stress played a more crucial effect on the occurrence of occupational low back pain than physical work factors did.

Objectives: Social support was previously regarded as acting only a stress modifier, but many recent studies have found a direct effect on stress. The purpose of this study is to evaluate the role of social support on job stress and psychosocial stress to determine whether it acts via direct effect or indirect effect. Methods: This study was performed in May 2003. The study population consisted of 425 male workers in an automobile factory in Korea. Data were collected with structured self-administered questionnaires. We used JCQ(Job Contents Questionnaires) to measure job stress and social support, and PWISF(Psychosocial Well-being Index-Short Form) to measure stress outcome. We analysed the relationships using Structural Equation Modeling software AMOS4. Results: It was found that social support acts both as a direct stressor and an indirect stressor via job stress. However the direct effect was double the indirect effect. Conclusions: The direct effect of social support on stress was the more major. Therefore social support is an independent stressor rather than a stress modifier in automobile factory workers.

Pancreatic cancer is one of the most lethal malignancies. Despite the availability of newer and better antineoplastic combinations, the 5-year survival rate for all stages of pancreatic cancer remains only 6%. Palliative care represents an important aspect of care in patient with pancreatic cancer. Thus, optimal palliation of symptoms to maximize remaining quality of life is of primary importance to most patients. This review discusses highlights the most significant problems faced when caring for patients with advanced pancreatic cancer. Common problems include pain, pancreatic insuffi ciency, anorexia-cachexia and depression. To provide optimal and meaningful supportive care for patients with advanced pancreatic cancer is complex and requires ongoing close monitoring of the physical and emotional aspects of the patient. Prompt management of the many symptoms and problems associated with pancreatic cancer is essential to minimize distress and improve quality of life for patients with this fatal disease. Recognizing end-of-life concerns and patient preferences during the dying process helps clinicians find ways to alleviate suffering for patients and families.

I analyze the effects of price matching guarantees when a firm can decide how much it will compensate for the price difference in a market with two different types consumers. Guarantees to compensate less than price difference will never be used and the effects of guarantees to compensate more than price difference do not depend on the compensation amount. Guarantees to compensate as much as price difference will be used as far as the number of loyal consumers is not too large, and profit does not decrease with this guarantees. The difference of the guarantees to compensate more than price difference and those to compensate as much as price difference arises when the number of loyal consumers is small. First, when the number is very small, the former will never be used. Second, when it is moderately small, both guarantees will be used. In case of the former, however, firms may be in the situation of Prisoner’s Dilemma in the sense that profits decrease when the demand of price sensitive consumer is price elastic. Finally, when a firm can decide the compensation amount, only the guarantees to compensate as much as price difference will be chosen when the number of loyal consumers is small. When the number is moderate, firms are indifferent between two guarantees and either of two guarantees will be chosen.
