Objectives: Modern people spend most of their day indoors. As the health impact of radon becomes an issue, public interest also has been growing. The primary route of potential human exposure to radon is inhalation. Long-term exposure to high levels of radon increases the risk of developing lung cancer. Radon exposure is known to be the second-leading cause of lung cancer, following tobacco smoke. This study measures the indoor radon concentrations in detached houses in area A of Chungcheongbuk-do Province considering the construction year, cracks in the houses, the location of installed detectors, and seasonal effects. Methods: The survey was conducted from September 2017 to April 2018 on 1,872 private households located in selected areas in northern Chungcheongbuk-do Province to figure out the year of building construction and the location of detector installed and identify the factors which affect radon concentrations in the air within the building. Radon was measured using a manual alpha track detector (Raduet, Hungary) with a sampling period of longer than 90 days. Results: Indoor radon concentrations in winter within area A was surveyed to be 168.3±193.3 Bq/㎥. There was more than a 2.3 times difference between buildings built before 1979 and those built after 2010. The concentration reached 195.4±221.9 Bq/㎥ for buildings with fractures and 167.2±192.4 Bq/㎥ for buildings without fractures. It was found that detectors installed in household areas with windows exhibited a lower concentration than those installed in concealed spaces. Conclusion: High concentrations of indoor radon were shown when there was a crack in the house. Also, ventilation seems to significantly affect radon concentrations because when the location of the detector in the installed site was near windows compared to an enclosed area, radon concentration variation increased. Therefore, it is considered that radon concentration is lower in summer because natural ventilation occurs more often than in winter.

Background: Information regarding the incidence and risk factors for deep vein thrombosis (DVT) detected by follow-up computed tomographic (CT) venography after pulmonary embolism (PE) is sparse. The aim of the present study was to identify the predictors of DVT in follow-up CT images, and to elucidate their clinical significance. Methods: Patients with PE were classified into the following three cohorts based on the time of indirect CT venography follow-up: within 1 month, 1 to 3 months, and 3 to 9 months after the initial CT scan. Each cohort was subdivided into patients with or without DVT detected by follow-up CT. Clinical variables were compared between the two groups. Results: Follow-up CT revealed DVT in 61% of patients with PE within 1 month, in 15% of patients with PE at 1 to 3 months, and in 9% of patients with PE at 3 to 9 months after the initial CT scan. Right ventricular (RV) dilation on the initial CT (odds ratio [OR], 8.30; 95% confidence interval [CI], 1.89-36.40; p=0.005) and proximal DVT at the initial presentation (OR, 6.93; 95% CI, 1.90-25.20; p=0.003) were found to independently predict DVT in follow-up CT images within 1 month, proximal DVT at the initial presentation was found to independently predict DVT in follow-up CT images at 1 to 3 months (OR, 6.69; 95% CI, 1.53-29.23; p=0.012), and central PE was found to independently predict DVT in follow-up CT images at 3 to 9 months (OR, 4.25; 95% CI, 1.22-4.83; p=0.023) after the initial CT scan. Furthermore, the detection of DVT by follow-up CT independently predicted the recurrence of venous thromboembolism (VTE) (OR, 4.67; 95% CI, 2.24-9.74; p<0.001). Conclusion: Three months after PE, DVT was not detected by follow-up CT in most patients with PE. RV dilation on the initial CT, central PE, and proximal DVT at the initial presentation were found to predict DVT on follow-up CT, which might predict VTE recurrence.

The importance of repeat screening for stomach cancer is well known to decrease deaths from stomach cancer. This study was aimed at assessing practice behaviors and to identify related factors in the aspects of demographic factors, health status and cancer risk recognition, attitude to cancer screening, health behaviors, and inhibiting or facilitating factors to stomach cancer screening in an urban area. Data was collected through self-administered questionnaires from 403 people aged 40 to 69 years from April 23th to May 15th, 2002. Practice behaviors were classified as : "ever" or "never", and "repeat" or "not repeat" grouped based on a recent 5 year screening history. The results were as follows: 1. Among the 403 subjects: "the ever group" was 23.8% and "the repeat group" was 4.0%, The rates of screening were 20.5% for men, 27.8% for those women, and 27.3% for aged 40-49, 24.5% for those aged 50-59, 19.0% for those aged 60-69. The rates of repeat screening were 4.0% for men, 4.1% for women, and 2.9% for those aged 40-49, 6.3% for aged 50-59, 2.5% for those aged 60-69. 2. The main factors associated with adherence to gastric cancer screening were education(post high school vs below : OR=2.44), previous cancer screening(yes vs no : OR=2.61), belief in personal health(no vs yes : OR=2.72), health status(unhealthy vs healthy : OR=3.40), possibility of cancer compared to others(low vs not low : OR=2.56), and regular exercise(yes vs no : OR=2.94). The main factor associated with adherence to gastric cancer repeat screening was other cancer screening(yes vs no : OR=6.33). Consequently, there is a need to change the recognition of the importance and necessity of stomach cancer screening in healthy conditions through health education, and to perform multiple screening tests each visit.

급변하는 사회의 변화로 말미암아 강력 범죄가 급격하게 증가하고 있다. 하지만 이에 대한 경찰 인력의 부족, 현장출동을 하더라도 범죄 상황에 대한 파악 등을 위한 시간 지연 등의 문제가 심각하다. 이미 오래전부터 관련 연구자들이 이를 해결하고자 많은 연구방법들을 제안하였다. 하지만 현실적으로 기존에 제안된 연구방법들이 아직도 부족한 점이 많다. 그러므로 본 연구에서는 스마트폰과 초고속 인터넷서비스 기술을 활용해서 범죄 상황에 대한 신속한 파악과 푸쉬 서비스를 사용해서 보안 서비스를 제공하고자 한다. 제안한 시스템은 스마트폰 사용자가 사전에 설정한 단축키를 누르면 주변에서 발생하는 음성 정보를 실시간으로 녹음하고, 저장된 음성 정보와 LBS 정보를 인증 과정을 거쳐 서버에 저장한다. 그리고 서버는 저장된 음성 정보와 LBS 정보를 푸쉬 서비스를 사용해서 가족들에게 알린다. 현재까지 우리는 제안시스템에 설계를 마쳤다. 그리고 스마트폰 사용자 앱과 인증 서버를 구현했다. 그리고 인증 서버에서 푸쉬 서비스를 사용해서 사용자 가족에게 메시지를 전달해서 알릴 수 있는 상태이다. 하지만 향후 연구를 통해 좀 더 제안한 연구가 타당성을 검토해야만 한다.

It is important to asess the risk factors of parenting and provide early intervention for promotion of the maternal caretaking ability. The purpose of the study was to identify the maternal burden of caretaking, the supporting and the educational need for the caretaking activities of the mother of infant. Sixty three mothers of infants who visited the wellbaby clinic of S university hospital and one health center during the period of November 1st, to 30th in 1996 comprised the subjects of this study, Data were gathered through the instruments that were developed by researcher. Statistical analysis of this study was used ANOVA and Pearson correlation. The results were as follows : 1) The mean score of the maternal burden of caretaking was 22.06. The maternal burden of caretaking was significantly high in the mothers who had vaginal delivery compare with the mothers who had caeserean section and in the muthers who gave artificial feeding compare with the group of breast or mixed feeding. 2) The mean score of the support need for the caretaking activities was 30.69. The support need for the caretaking activities was significantly high in the mothers who had the second child, compare with the mothers who had first or third child. And the support need for the caretaking activities was significantly high in the mothers who had caretaking help compare with the mothers who had no caretaking help. The specific subjects of 'mother-infant interaction', 'immunization' and 'prevention of accident' on the support need for the caretaking activities were relatively high. 3) The mean score of the educational need of caretaking activities was 29.3. The educational need of caretaking activities was significantly high in the mother who had the second child compare with the mothers who had first or third child. And the educational need of caretaking activities was significantly high in the mothers who had caretaking help compare with the mothers who had no caretaking help. The specific subjects of 'mother-infant interaction', 'emergency care' and 'prevention of accident' on educational need of caretaking were relatively high. 4) The maternal burden of caretaking was not correlated with the support need or the educational need of caretaking activities. But the support need of caretaking activities was significantly correlated with the educational need of caretaking activities. 5) The support and educational need of caretaking activities were significantly high in the mothers who wanted home care for caretaking their infants. Through the study, it was found that there is considerable maternal burden of caretaking as well as the support and educational need on the caretaking activities in the mothers whose child is young. Therefore developing the systematic and effective program is needed to meet the mother's need. The results of this study will be useful resources to develop the program. On the other hand, it can be recommanded that home health care will be one of the approach to support the mothers caretaking activities.

Objectives: The purpose of this study is to investigate the weight loss effects of auricular acupuncture in obese patients. Methods: Six databases (Research Information Sharing Service [RISS], Korean studies Information Service System [KISS], Oriental Medicine Advanced Searching Integrated System [OASIS], PubMed, The Cochrane Library, China National Knowledge Infrastructure [CNKI]) were searched up to May 20, 2020. Eight eligible randomized controlled trials were included the present study. The quality of included studies was assessed by the Cochrane risk of bias tool and a meta-analysis was performed by Review Manager software. A meta-analysis was conducted using a random-effects model and a subgroup analysis was performed to detect the sources of heterogeneity, identify the selection of acupuncture methods and explore its contributions to the weight loss effects. Results: Among 8 trials, 5 trials used auricular acupuncture and 2 trials used auricular acupressure, 1 trial used both types of intervention. Most commonly selected acupoints were Shenmen (TF4) and stomach (CO4). Treatment duration was six to twelve weeks, and total treatment session was six to twelve. Compared to the control groups, auricular acupuncture significantly decreased body weight, body mass index (BMI), high density lipoprotein-cholesterol (HDL) and ghrelin. For the selection of acupuncture methods, both methods performed similarly in most outcome except waist circumference (WC), body fat percentage (BFP), and triglycerides (TG). Conclusions: We found that auricular acupuncture can be effective for weight loss and controlling appetite. However, the findings should be interpreted with caution due to heterogeneity. So further vigorous and well-designed studies should be conducted to strengthen the evidence of the use of auricular acupuncture for obesity.
