Objectives: The major objective of this study was to investigate the prevalence of and risk factors for latent tuberculosis infection (LTBI) among employees at a workers' compensation hospital. Methods: Among the 394 employees at Incheon Hospital, 362 were enrolled in the study. An interferon-gamma release assay(IGRA) for diagnosis of LTBI was performed using QuantiFERON$^{(R)}$ TB Gold In-Tube(QFT-IT). Risk factors for LTBI were analyzed using logistic regression analysis. Results: The overall prevalence of LTBI was 32.0%(116/362). The non-medical departments have a significantly high prevalence compared to medical departments(39.7% vs 23.2%). In multivariate logistic regression analysis, experience working in the pneumoconiosis hospital(OR, 3.6; 95% CI, 1.3-10.3) was associated with development of LTBI. Conclusions: Korean guidelines for the management of tuberculosis recommend annual regular health examinations for TB and LTBI for health care workers(HCWs). Considering the high prevalence of and risk factors for LTBI among non-HCWs, it suggests a need for annual regular health examinations for TB and LTBI for all employees at workers' compensation hospitals, including pneumoconiosis hospitals.

Objectives: This study examined the characteristics and nutritional risk of the elderly who receive home delivery services. We then analyzed the effects of the characteristics of the elderly who receive the home-delivery meal service on their nutritional risk. Methods: A total of 220 respondents who receive home-delivery meal service in Seoul participated in the survey. The survey consisted of the characteristics of the elderly (health status, tooth condition, physical activity, social participation activity, depression and relationship with neighbors), nutritional risk assessment and other general matters. The data was analyzed by using the SPSS program. Cross-tabulation analysis, t-test, correlation analysis and regression analysis were all conducted. Results: 47.0% of the subjects were under 80 years old and 53.0% were over 80 years old, The nutritional risk score, as evaluated by a Nutrition Screening Initiative (NSI) checklist was 10.7 points, and the high nutrition risk group was 91.5% of the subjects. The subjective self-health status score was 2.24 points (out of a total of 5 points) and the tooth status score was 3.30 points. The physical activity level was 2.17 points for the under 80 years old group and 1.76 points for the over 80 years old, and there was a significant difference according to age (p<0.01), The higher the health status, tooth condition, physical activity and social participation activity level, the lower was the nutritional risk. Further, the higher the degree of depression, the higher was the nutritional risk. Conclusions: For the healthy life of the elderly in the community, various welfare policies should be planned to increase social participation as well as to promote physical health and reduce depression.

Purpose: This study identifies preventive measures for VOC management by analyzing the causes and effects of factors that contribute to high risk service failure using FMEA on KORAIL VOC data. Methods: Two research methods were used. First, a Risk Priority Number (RPN) was assigned to each KORAIL VOC based on Failure Mode and Effect Analysis (FMEA). Second, multiple regression analysis was run with RPN factors that include severity, occurrence, and detection as the independent variables and customer dissatisfaction as the dependent variable. Results: Multiple regression analysis showed that RPN factors including severity, occurrence, and detection had significantly positive relationship with customer dissatisfaction. Based on these results, an FMEA was performed on VOC categories with high RPN for railroad stations including platform, ticketing, ticket verification, parking, and escalator, and VOC categories with high RPN for trains including entrance doors, cafes, air quality, announcement, and ticket verification. Conclusion: This study has practical implications to service failure management. A priority order using FMEA was established for the list of customer dissatisfactions that should be addressed to actively manage service failure, and strategies for tackling this priority list are offered.

Objective : To determine demographic, clinical, health care utilization factors predicting unplanned readmission(within 28 days) to the hospital. Methods : A case-control study was conducted from January to December 2009. Multiple logistic regression was used to examine risk factors for readmission. 180 patients who had been readmitted within 28 days and 1,784 controls were recruited from an university hospital in Seoul. Results : Six risk factors associated with readmission risk were identified and include mail sex, medical service rather than surgical service, number of comorbid diseases, type of patient's room, lenth of stay, number of admissions in the prior 12 months. Conclusions : One of the association with readmission risk identified was the number of hospital admissions in the previous year. This factor may be the only risk factor necessary for assessing prior risk and has the additional advantage of being easily accessible from computerized medical records without requiring other medical record review. This risk factor may be useful in identifying a group at high readmission risk, which could be targeted in intervention studies. Multiple risk factors intervention approach should be considered in designing future prevention strategies.

An attractive user interface (UI) design with a clear user experience (UX) is the key for the success of applications. Therefore software development projects require very close collaboration between SI developers and front-end service developers. However, methodologies for software development only exist with inadequate development processes or work standards for collaboration. This survey derived 13 risk factors in developing UI/UX from 113 risk factors of IT projects through a questionnaire and factor analysis and proposed a collaboration-based UI/UX development model that can eliminate or mitigate six risks with high weights and reliability. To extract risk factors with high reliability, factor and reliability were analyzed to extract 13 major risks, and based on the expert opinions and the results of correlation analysis, UI/UX development stages were classified into planning, design, and implementation. The causal relationships between risks were verified through regression analysis. This study is the first to expertly analyze major risks based on collaboration in UI/UX development and derive a theoretical basis that can be used in project risk management. These findings are expected to provide a basis for research on development methodologies for higher levels of front-end services and to construct rational collaboration systems between SI practitioners and front-end service providers.

Background: Breast cancer is worldwide the most common cancer in women and is a major public health problem. Genes with high or low penetrance are now clearly implicated in the onset of breast cancer, mostly the BRCA genes. All women in families at high risk of breast cancer do not develop tumours, even when they carry the familial mutation, suggesting the existence of genetic and environmental protective factors. Several studies have shown that consanguinity is linked to a decreased or an increased risk of breast cancer, but to the best of our knowledge, there is no study concerning the association between consanguinity and the occurrence of tumours in women with high risk of breast cancer. The objective of this study was to examine whether parental consanguinity in families with genetic predisposition to breast cancer affect the risk of siblings for having this cancer. Materials and Methods: Over a six-year period, 72 different patients with a histological diagnosis of breast or ovarian cancer from 42 families were recruited for genetic counselling to the Department of Medical Genetics, Rabat. Consanguinity rate was determined in cases and compared to the consanguinity rate in the Moroccan general population. Results: Consanguinity rates were 9.72% in patients and 15.3% in controls, but the difference was statistically not significant (p>0.001) and the mean coefficient of consanguinity was lower in breast cancer patients (0.0034) than in controls (0.0065). Conclusions: Despite the relatively small sample size of the current study, our results suggest that parental consanguinity in Moroccan women might not be associated with an altered risk of breast cancer. Large scale studies should be carried out to confirm our results and to develop public health programs.

이른바 코로나19 대유행으로 철도서비스 경영 역시 유례없는 상황을 맞이하고 있다. 본 연구에서는 코로나19 유행기간 동안 고속철도를 이용한 고객을 대상으로 설문조사를 진행하여 감염병이 철도서비스 고객경험에 미치는 영향을 탐색하였다. 연구결과, 철도운영기관이 제공하는 방역관련 서비스에 대해 고객이 높은 수준으로 지각할수록 고객만족도와 충성도가 증가하는 것으로 나타났다. 또한 고객 별로 코로나19에 대해 위험하게 생각하는 수준에 개인차가 있기 때문에, 고객의 코로나19 위험지각의 조절역할도 실증하였다. 그 결과, 코로나19에 대한 고객의 위험지각이 적정한 수준일 때에는 서비스 기관의 방역관련 서비스 속성이 고객만족 형성에 큰 영향을 미치지만, 고객의 위험지각수준이 상당히 높은 경우에는 그 영향력은 유의하지 않은 것으로 나타났다. 결국 감염병에 대한 위험이 완벽히 소멸되는 것만이 서비스 산업의 완벽한 회복을 가져다줄 것이다. 그럼에도 감염병 유행기간에는 서비스 운영기관이 방역활동을 철저히 하고, 고객에게 이에 대해 충실히 커뮤니케이션 하는 것이 주요한 서비스 속성이 된다는 것을 확인하였다.
