Purpose: The purpose of this study was to provide basic data on the infection prevention management program, which is one of the infectious disease control program by identifying the prevalence and risk factors of latent tuberculosis infection (LTBI) in healthcare workers. Methods: We surveyed a total of 3,046 LTBI test results, including those of 2,269 existing staff and 777 new employees. An interferon-gamma release assay (IGRA) for the diagnosis of LTBI was performed using QuantiFERON^®-TB Gold In-Tube (QFT-IT). The risk factors of LTBI were analyzed using logistic regression analysis. Results: The overall prevalence of LTBI was 16.0% (487/3,046). The prevalence of LTBI in the existing staff was 17.9% (406/2,269) and the prevalence of LTBI in new employees was 10.4% (81/777). Multivariate logistic regression analysis revealed that the risk factors of latent tuberculosis infection among the existing staff were gender, age and work period wheres, the risk factor amongst the new employees depended on their age. Conclusion: The LTBI was not related to the type of occupation and work unit. Therefore, while establishing an infection control program for the prevention of tuberculosis infection at medical institurions, institutional heads and infection control experts should encompass a policy for all the employees.

Recently, IT outsourcing has become a very important management strategy which implements information systems in organizations. This paper investigates the risks and strategic recognition as a key factors affecting on the degree of IT outsourcing. Specifically the risks of IT outsourcing and its four components-risk of control, risk of economical, risk of technical, risk of relational - are examined to be a negative effect on the degree of outsourcing. And strategic recognition about outsourcing is examined how to affect en the risks and the degree of IT outsourcing. To empirically test these relationships, data ere gathered from senior IT managers in 86 corporations. Results of this study show that the degree of outsourcing is strongly influenced by risk of control, risk of economical, risk of relational. But risk of technical does not influence on the degree of outsourcing. And strategic recognition about outsourcing is found that is negative effect on the risks of IT outsourcing and positive effect on the degree of IT outsourcing. The results provide a good framework to minimize the risks for IT outsourcing success.

Today, IT outsourcing has become a very important management strategy of implementing information systems in organizations. This paper investigates the risks and strategic recognition as a key factors effecting on the degree of outsourcing, Specifically the risks of outsourcing and its four components-control risk, economical risk, technical risk, relational risk-are examined to be a negative effect on the degree of outsourcing. And strategic recognition about outsourcing is examined to be a mediator factor between the risks and the degree of outsourcing. To empirically test these relationships, data are gathered from senior IT managers in 62 corporations. Results of this study show that the degree of outsourcing is strongly influenced by control risk, economical risk, relational risk. But technical risk does not influence on the degree of outsourcing. And strategic recognition about outsourcing is found that is mediator concern with the risks and the degree of outsourcing. The results indicate to provide a good framework to minimize the risks for IT outsourcing success.

This study investigated the relationship between knowledge of COVID-19, the risk of exposure to subjective infectious diseases, and the degree of infection control practices for dental personnel. For dental personnel currently working in dentistry, a survey consisting of 10 questions about COVID-19 knowledge and 63 questions about infection control practices was conducted. This study analyzed 126 survey data collected by distributing questionnaires form May 30 to June 20, 2020. Data was analyzed using t-test, ANOVA, and Pearson correlation. The average level of knowledge of COVID-19 was 5.44 out of 10, the average risk of exposure to infectious diseases was 3.86 out of 5, and the average level of infection control practices was 4.05 out of 5. The risk of exposure to infectious diseases was positively correlated with dental waste (r=.184). It was found that there was a significant positive correlation between infection control practices and sub-factors of infection control practices (p<0.001). To prevent the spread of COVID-19 and infectious diseases and to reduce the risk of exposure to infectious diseases for dental personnel, the practice of infection control should be improved. It is necessary to cultivate infection control experts and have mandatory infection control education and social regulations.

In the decision of a collision avoidance action for navigators and intelligent ships, it is necessary to evaluate the degree of surrounding risks and to control them effectively. In this paper, we propose the new methodology for navigational risk evaluation and control at sea. In the methodology, navigation risk is evaluated in two dimensions using Even Risk Contour on the basis of the concept of contour line. In addition, the movement information of dangerous targets is assessed continuously and precisely with wide band data. The presented technique is useful for the safety navigation at the heavy traffic sea and will be applied for the ultra automatic ship.

Background: Breast cancer in Kazakhstan and its Kyzylorda oblast is the most prevalent cancer in women and features increasing trends of incidence. The aim of study was to reveal risk factors for breast cancer among women of Kyzylorda oblast of Kazakhstan. Materials and Methods: A hospital-based case-control study was conducted at Kyzylorda oblast Oncology Center, including 114 cases of breast cancer and 196 controls. Binary logistic regression analysis was performed. Results: Social and behavioral risk factors for breast cancer were evaluated, among which unfavorable living conditions, chronic stress, unilateral breastfeeding, breastfeeding less than 3 months and over 2 years, abortions, and hereditary predisposition were found to be related with increased breast cancer risk. Breastfeeding for 6-24 months was found to be protective. Conclusions: The findings may have significant impact on activity planning aimed towards breast cancer reduction among women in Kazakhstan.

Gall bladder cancer is generally fatal. The high morbidity and mortality due to gall bladder cancer exerts a significant impact on efforts towards cancer control in high risk populations of the World and a rationale program for control of gall bladder cancer mortality has remained as an unmet need in these populations. Currently there are no effective strategies for controlling gall bladder cancer mortality. This mini review is to highlight the need and feasibility for secondary prevention of gall bladder cancer by screening in high risk populations. A way forward is to assess the role of secondary prevention of gall bladder cancers by conducting randomized-controlled screening trials in high risk populations.

해양 유류오염 및 유출량 증가에 따라 방제능력을 추가로 확보에는 많은 위험이 있다. 현재 해역에 배치된 방제선을 재배치하여 유휴능력을 개선하고 부족한 해역에 배치하고자 하고자 해양오염지수를 도출하고 해역별 해양오염지수 대비 방제능력을 비교하여 방제선 배치의 적절성을 검증하였다. 해양오염을 유발하는 항목에 대한 해역별 수치에 전문가 집단에서 도출한 가중치를 곱하여 해양유류 오염위험지수를 도출하였다. 해역별 해양오염 위험지수(F) 대비 방제능력(A)이 부족한 해역은 목포(F:13.4, A:1.9), 부산(F:14.3, A:6.4), 여수(F:21.5, A:16.6)이고, 여유있는 해역은 마산(F:5.9, A:13.3), 군산(F:1.7, A:8.3), 제주(F:2.7, A:6.9)이다. 따라서 해양오염 위험도에 비례한 평준화된 방제능력을 제고하기 위해 방제능력 여유 해역인 마산, 군산, 제주의 방제선을 방제능력 부족해역인 목포, 부산, 여수으로 재배치되어야 함을 시사한다.

The risk management case is an organization's formal arrangement to ensure the safety of its work activity within risk management system. It allows an organization to demonstrate its capability in achieving its safety objectives and in meeting regulatory requirements. This paper presents how the safety assessments are described, prepared and maintained to meet the criteria specified by the upcoming safety regulations. We propose the elements of risk management system that include arrangements for the ongoing identification of hazards, assessment of risks and the implementation of necessary control measures.
