OBJECTIVE: This study was performed to determine the smoking status and its associated factors in military life among young Korean men to provide date for smoking prevention in military areas as a part of the health promotion program for soldiers. METHODS: 1,033 infantrymen serving in 17 military units, which are located in suburbs of K city, were enrolled in this study. A questionnaire on the soldiers smoking status and other various characteristics was obtained from October 2nd to 12th, 2000. Logistic regression analysis was performed on the various variables in order to determine the factors related to smoking. RESULTS: 1) 830(80.3%) out of 1033 subjects had smoked cigarettes and 759 persons(73.4%) were regular smokers. 2) Among the 734 soldiers who started smoking before their military service, 714 soldiers(97.2%) continued to smoke after, while 45 soldiers(15.0%) among the 299 non-smokers started smoking after joining the army. 3) Through the logistic regression analysis, the education level, specialty in the army, smoking amongst the friends they met before military service, smoking amongst soldiers in the army, dating girl friends, drinking, satisfaction with their army lives and the presence of convenient smoking places at the barracks were significant factors related to the prevalence of smoking in soldiers. CONCLUSION: the factors related with incidence of smoking in the army are the complicated interactions among the individuals personal background, general charcterisitcs of the solider and the special environment in the barracks. Therefore, to improve national soldiers' health, an active non-smoking campaign and education should be pushed to discourage smoking in the barracks.

An association of low total cholesterol in blood with psychiatric diseases and suicidal behavior has been suggested. As part of an attempt to further explore this relationship, we examine first, whether serum cholesterol levels in psychiatric patients with suicidal attempt would be lower than in non-suicidal psychiatric inpatients or normal controls, second, whether such significant difference of cholesterol levels would be present when the diagnostic groups are analyzed separately, third whether low cholesterol level would be associated with a history of serious suicidal attempts, and finally, whether low cholesterol level in suicide attempters is as state or a trait marker. We determined the serum cholesterol levels in 231 patients admitted to an emergency room following an suicidal attempt, in the same numbers of age-, sex- and diagnosis-matched non-suicidal psychiatric controls, and in the same numbers of age-, sex matched normal controls. The seriousness of an attempt was divided into 5 grades according to the degree of the resulting medical injury. Total cholesterol levels in suicide attempters were significantly lower compared with both psychiatric and normal controls, when sex, age, and nutritional status(i.e., body mass index) were controlled for. This significant relationship was observed in major depressive disorders and personality disorders, but not in schizophrenia and bipolar type I disorders. The severity of suicide by a lowering of blood cholesterol was related to the magnitude of the cholesterol reduction. After treatment of their psychiatric ailments, the cholesterol levels in suicide attempters were significantly increased. This result suggests that low cholesterol level in psychiatric patients might be a potential biological marker of suicide risk. It is hypothesized that low cholesterol levels is associated with the suicide by modifying the serotonin metabolism, the production of interleukin-2 and melatonin metabolism in psychiatric patients.

Objective: Among old adults, caring for a spouse with cognitive decline is well-known to be associated with significant risk to the caregiver’s health such as cardiovascular disease, depression and, especially, cognitive impairment. It is important to understand the caregiving-related risk factors for caregiver’s cognitive decline. Therefore, in this study, we examined the impact of caregiver’s burden on the modifiable lifestyle factors influencing cognitive decline among spousal caregivers (SCGs), focusing on nutritional status which contribute to SCG’s cognitive decline. Methods: A total of 44 subjects were included in the analysis. As clinical assessment, we evaluated the care burden (Zarit Burden Interview), depression (Geriatric Depression Scale), sleep quality (Pittsburgh Sleep Quality Index), cognitive function (Mini-Mental State Examination, MMSE) physical activity (International Physical Activity Questionnaire), and nutritional status (Mini Nutritional Assessment). Results: High Neuropsychiatric Inventory (NPI) score and low MMSE score were significantly correlated with increased care burden. The SCG’s caregiving burden was significantly associated with the risk of malnutrition and increased level of depressed mood. These significant relationships unchanged even after adjusting for care-recipient’s MMSE or NPI score. Conclusion This study provides substantial evidence that SCGs of cognitive impairment are at risk for depression and malnutrition, which can further affect cognitive decline. As such, these factors should be well assessed and monitored among SCGs for patient with cognitive impairment.

PURPOSE: The purpose of this study was to identify relationships between quality of sleep, symptom cluster, depression, environmental disorder, and quality of life among hospitalized cancer patients. METHODS: The subjects were 114 patients who underwent chemotherapy for colon cancer, gastric cancer, gynecologic cancer and breast cancer. They were recruited from the cancer center of a university hospital. Data were collected from August 4th to 30th, 2011. The questionnaires included the Korean sleep scale A (quality of sleep), MDASI-K (symptom cluster), the environmental sleep disturbing scale, Zung's depression scale, and the Korean version of EORTC QLQ-C30. The collected data was analyzed by t-test, ANOVA, multiple regression analysis using the SPSS 19.0 program. RESULTS: Functional QOL was negatively associated with symptom QOL (r=-.798, p<.001). Symptom cluster, depression, & spouse (46.3%) were the most powerful predictors for functional QOL (46.3%) and symptom QOL (53.4%). CONCLUSION: It is evident that oncology nurses need to evaluate two dimensions of quality of life for cancer patients, for example, functional and symptom QOL. We recommend nurses develop specific protocols for relieving physical symptoms and alleviating depression, and furthermore test the effectiveness of them.

PURPOSE: To find the effect of visual feedback of head angle with using a mobile posture-aware system on craniocervical angle and neck and shoulder muscles fatigue for preventing or decreasing the forward head posture. METHODS: Twenty-four healthy young adults in Chungbuk to participate in this study. The subjects started to watch a movie clip for 10 minutes with visual feedback in 0°, 30°, and 60° of head angles. During the task, surface electromyography (EMG) was used to collect data from the upper trapezius (UT), sternocleidomasetoid muscle (SCM), cervical erecter spinae (CES) during watching the smartphone. Craniocervical angles were measured using a sagittal-view photograph of the subject in a sitting posture. A one-way repeated analysis of variance with a significant level of 0.05 used for statistical analysis. RESULTS: Craniocervical angle with 0° visual feedback was significantly greater than 30°and 60°. Craniocervical angle with 30° visual feedback was significantly greater than 60°. In addition, MDF of UT muscles in 0° and 30° of visual feedback was significantly greater than 60°. CONCLUSION: We concluded that 0° visual feedback of head angle with using a mobile posture-aware system would be beneficial to prevent or decrease forward head posture during watching a smartphone. We also could recommend using of 30° visual feedback in case of caring UT muscle fatigue primarily.

Purpose: To identify the differences in perception of and adherence to the COVID-19 social distancing behavior guidelines among health care workers, patients, and the general public and to use them to prevent the spread of COVID-19. Methods: From October 16 2020 to November 30, 2020, a survey was conducted among 85 health care workers, 85 patients, and 82 general public regarding the perception of and adherence to the COVID-19 social distancing behavior guidelines. Results: Patients scored significantly higher than the general public in the adherence to the COVID-19 social distancing behavior guideline, and there was no difference between health care workers and general public, and patients and health care workers. In the multivariate analysis, the factors that influence the adherence of the COVID-19 social distancing behavior guide were found in women and the perception of the COVID-19 social distancing behavior guideline. Conclusion In order to promote the implementation of the COVID-19 social distancing behavior guideline, it is necessary to increase the perception of the COVID-19 social distancing behavior guideline and provide additional education in men. It is necessary to investigate the reason behind why men have low adherence to the COVID-19 social distancing behavior guideline.

PURPOSE: The aim of this study is to present our experience with minimally invasive surgery (MIS) for congenital cystic adenomatoid malformations (CCAMs). METHODS: The medical records of infants under 2 years of age who underwent operation for a CCAM from 2009 to 2014 were retrospectively reviewed. RESULTS: MIS (9 of thoracoscopy and 1 of laparoscopy) was performed for 10 infants (male:female = 7:3) with CCAM. CCAM were discovered prenatally around gestational age of 24.7 weeks. The median gestational age was 38.6 weeks, and the median body weight was 2,817.5 g. None had respiratory distress after birth. The median age at the time of operation was 0.94 years (range: 8 days-1.66 years). Two underwent the operation during the neonatal period; one because of a coexisting large esophageal duplication cyst and the other due to diagnostic uncertainty. While awaiting operation, 5 of CCAM had grown without respiratory symptoms, and 2 infants had experienced pneumonia. The mean operative time was 98 minutes (range: 70-227 minutes), and there were no conversions or perioperative complications. The infants resumed enteral feeding within 2 days and were discharged within 7 days, except for 1 infant who underwent esophageal duplication cyst excision. During the follow-up period, there were no cases of either remnant lesions or respiratory symptoms. CONCLUSION: MIS for CCAMs is safe and feasible, with excellent cosmesis and short hospital stays. Increasing experience with various MIS procedures will widen the indications for MIS in lung pathology.

PURPOSE: The aim of this study was to evaluate observed changes in the prevalence of biopsy-proven Helicobacter pylori infection in Korean children with functional recurrent abdominal pain during the past 18 years. METHODS: Between July 1991 and December 2008, 1,194 children with functional recurrent abdominal pain (499 males and 695 females) 9.2+/-3.1 years of age were included. Upper gastrointestinal endoscopies were performed in all patients. H. pylori infection was assessed by the CLO test. Changes in the prevalence of the endoscopic diagnosis of H. pylori infection during 18 years were analyzed. RESULTS: The prevalence of H. pylori infection between 1991 and 1993, 1994 and 1996, 1997 and 1999, 2000 and 2002, 2003 and 2005, and 2006 and 2008 were 25.1% (56/223), 23.1% (45/195), 19.3% (28/145), 16.1% (39/242), 11.3% (24/213), and 10.8% (19/176), respectively; these serial decreases in the prevalence over 18 years were statistically significant (p<0.001). Regardless of gender and age, the prevalence of H. pylori infection decreased. This decrease was inversely related to socioeconomic improvement as represented by the per capita gross national income growth of Korea. CONCLUSION: The prevalence of H. pylori infection has decreased significantly for the past 18 years in Korean children. This decrease might be caused by an improvement in socioeconomic status.

Contrary to metastatic tumors of the omentum, primary tumors of the omentum are very rare. A 10-year-old girl presented with low abdominal pain. Imaging studies showed a multiseptated hemorrhagic tumor. The mass from the omentum was removed completely and confirmed as a malignant rhabdoid tumor. Despite aggressive chemotherapy, she died after 9 months due to disease progression. We report one case of primary malignant rhabdoid tumor of the omentum for the first time.

The goal of this review is to present the similarities and differences among the latest guidelines for noninvasive diagnosis of hepatocellular carcinoma (HCC) of American Association for the Study of Liver Disease (AASLD), European Association for the Study of the Liver (EASL), Liver Imaging Reporting and Data System (LI-RADS), Asian Pacific Association for the Study of the Liver (APASL), and Korean Liver Cancer Association-National Cancer Center (KLCA-NCC) of Korea. In 2018, major guideline updates have been proposed by the AASLD, EASL and KLCA-NCC; AASLD newly incorporated LI-RADS into their HCC diagnostic algorithm. The AASLD and EASL guidelines now include magnetic resonance imaging (MRI) using hepatobiliary contrast media as a first-line diagnostic test in addition to dynamic computed tomography and MRI using extracellular contrast media and the KLCA-NCC and EASL guidelines also include contrast-enhanced ultrasound as a second-line diagnostic test. We will comprehensively review the HCC surveillance and diagnostic algorithms and compare and highlight key features for each guideline. We also address limitations of current systems for the noninvasive diagnosis of HCC.
