  • The present study assessed children's perceptions of risk of sexual abuse before and after participation in a sexual abuse prevention program, and investigated the effects of the sexual abuse prevention program on the children's emotional response. The subjects for this study were 135 3rd and 145 6th graders, attending elementary school in Seoul. Instruments were the Sexual Abuse Situational Risk (Jacobs, Hashima, & Kenning, 1995) and the Children's Emotional Response Questionnaire (Garbarino, 1987). The results of this study were that (1) children's perceptions of the risk of sexual abuse by a stranger decreased, relative to those by familiar persons which increased after the program. Especially, 6th graders had higher perceptions of the likelihood of abuse by familiar persons than 3rd graders. Girls had higher perceptions of risk than boys. (2) Children perceived adults as more dangerous than adolescents both before-and after-program. (3) Children's perceptions of the risk of sexual abuse in public settings decreased, relative to perceptions of risk in private settings which increased after the program. Girls had higher perceptions of the liklihood of abuse in private settings than boys; no significant difference was found by grade. (4) Children's emotional response did not reveal a significant change between pretest and posttests.

  • Background: Breast cancer incidence and mortality rates are increasing in North-Eastern Brazil and the patients with the disease often presented at advanced stages. The present study was focused on identifying variables that affect women's frequency of breast self- examination (BSE) performance. Materials and Methods: Data on BSE, socio-economic parameters and risk factors for breast cancer were obtained from 417 women from a community in North-Eastern Brazil by a self-informant method. To identify independent variables that affect frequency of BSE, nominal logistic regression analysis was performed. Results: Of 417 women, 330 (79.3%) reported performing BSE. Compared to high-income women, BSE performance by low-income women every month was 7.69 (OD=0.130; CI 95%: 0.044- 0.0386; p=0.000) times lower. Women who did not live in a stable union performed BSE each month 2.73 (OD=0.366; CI 95%: 0.171-0.782; p=0.010) less often than those living in a stable union. BSE performance every month and every six months or every year by women with poor knowledge about risk factors for breast cancer was 3.195 (OD=0.313; CI 95%: 0.141- 0.695; p=0.004) times and 2.028 (OD=0.493; CI 95%: 0.248- 0.979; p=0.043) times lower, compared to women with good knowledge. Participants who had a close relative with cancer performed BSE every month and every six months or every year 2.132 (OD=0.469; CI 95%: 0.220-0.997; p=0.049) times and 2.337 (OD=0.428; CI 95%: 0.219-0.836; p=0.013) times less often, compared to those women without close relatives with cancer. Conclusions: The results of this study indicated that income, marital status, knowledge about risk factors and having a close relative with breast cancer, affect the frequency of BSE performance. Information about risk factors in public health campaigns could additionally strengthen avoidance behaviour and also motivate BSE performance.

  • The two-stage minimum risk point estimation of mean, the probability of success in a sequence of Bernoulli trials, is considered for the case where loss is taken to be symmetrized relative squared error of estimation, plus a fixed cost per observation. First order asymptotic expansions are obtained for large sample properties of two-stage procedure. Monte Carlo simulation is carried out to obtain the expected sample size that minimizes the risk and to examine its finite sample behavior.

  • This study focuses on the risk management of "Digital Goods" appeared with the progress of information technology(IT) in international transaction. As a result of that digital goods have a lot of uncertainty between the general goods or service which have been deal with object of international transaction broadly because digital goods hold uniqueness. In this study, the author give a definition of "Digital Goods" and make an examination of uniqueness of that in international transaction. Next, six risks are defined base on risk theory and risk analysis matrix applying risk mapping model is made. Conclusionally, risk transfer as insurance is adequate to manage business risk, security risk, credit risk and legal risk. Meanwhile, risk avoidance is adequate to manage reputation risk and market risk. But, this study have following three limits. Firstly, concerning definition of the risk, real case is not applied owing to lack of transaction data. Secondly, measuring of the risk is not based on absolute data but relative data. Lastly, suggesting way of risk management is not concrete and practical to international trader of digital goods.

  • This study was undertaken to evaluate the relation between obesity and dietary life of children aged 4-7 divided into two groups based on height for age, weight for age and weight for height. Controls were selected based on sex and age similar with those of cases. Cases and controls were selected using the combination of weight for height, weight for age and height for age by the World Health Organization standard. Cases were 23 children judged as obese. Controls were 37 judged as normal. Whether their mother had a job or not, showed relative risk 1.35(95% C1 0.32-5.64). In obese group, employmental statue of mother was 17.4% compared with 13.5% in control group. In mother's concern for cooking pattern, the relative risk was 5.64 and 95% CI was 1.70-18.66 in the item of "We consider the color arrangement when we serve foods" which was the highest rate. The item having the lowest relative risk was "We cook the meal by ourselves with spending time" which of the relative risk was 0.52 and 95% CI was 0.16-1.65. The item having a great significance in the dietary habit of subjects were "They beat the tablewear with the chopstick"(RR:1.64, 95% CI:0.22-12.73) and "I talk with food in my mouth"(RR :1.11, 95% CI:0.39-3.15), and the other items didn't show significancy. Number of food eating per day for male was 30.0$\pm$10.93 in obese group where as 23.2$\pm$9.80 in control group. 22.3$\pm$4.56, 21.8$\pm$10.91 were taken obese group and control group respectively in female. In the survey for general habit in life, the item of "We has a time for conversation with our family regularly" was high correlation to obesity and item of "We made our children change clothes and go to toilet themselvesj has slight relation to obesity. From above, we observed normal and obese children had different factors such as mother's attitude for preparing meals, table manners and habit of living. So we should take a continuous interest in children's dietary life in order to correct the wrong dietary habit and to protect from future problems.

  • The objectives of this study were to compare the relative risk of all-cause mortality and cause-specific mortality associated with Asian dust events, and especially to investigate the effects on the susceptible population such as the elderly and children, which were based on the data in Seoul from 2000 to 2006. Both of the study periods with/without Asian dust days, respiratory-cause mortality was the highest, followed by cardiovascular-cause mortality and all-cause mortality in sequence among mortality related to air pollution for all-aged group. As to susceptible group, the relative risk of mortality is the highest for +65 yrs group among all-cause mortality. According to comparison of mortality with/without Asian dust days, the relative risk of all-cause mortality is larger in the model with Asian dust days than the one in the model without Asian dust days among all age group (except for under 15 yrs group) and all air pollutants. The relative risk of cause-specific mortality (except for ozone in under 15 yrs group in case of respiratory-cause mortality, and ozone in all age group and over 65 yrs group in case of cardiovascular-cause mortality) per IQR increase of each pollutant is larger in the model without Asian dust days.

  • Candida albicans is one of the most frequently isolated fungal pathogens in human. Recently, the prevalence of candida infection has markedly increased, partially due to the increase of immunocompromised hosts. Proposed virulence factors of the pathogenic Candida are the ability to form hyphae to adhere to epithelial cell surfaces, and to secrete acid proteinases and phospholipases. We measured the relative cell surface hydrophobicity (CSH) and the ability of proteinase production (PROT), phospholipase production (PLase), adherence to host epithelium (ADH), and hyphal transition (Germ). The relative risk of virulence factors was analyzed by lethality test in murine model of hematogeneously disseminated candidal infection. According to Cox's proportional hazard analysis, the statistically significant virulence factors were PROT, ADH, and CSH. PROT was the highest risk factor of them. To evaluate the applicability for the diagnosis and treatment of Candidiasis, we examined the protective effect of the active and passive immunizations with the materials purified from virulence factors and antibodies to them in Candia-infected mice model. The mean survival times of active and passive immunized groups were slightly longer than those of non-immunized groups.

  • A successful fire risk assessment is depends on identification of risk, the analytical process of potential risk, on estimation of likelihood and the width and depth of consequence. Take the influence on enterprise into consideration, Fire risk assessment could carry out along the evaluation of the risk importance, the risk level and the risk acceptance. A large part of the limitation of choosing the risk assessment techniques impose restrictions on expense and time. If it is unnecessary high level risk assessment or Probabilistic Risk Assessment of buildings, in compliance with the Relative Ranking Method, Fire risk indexing and assessing is possible. As working-level technique, AHP method is useful with practical technique.

  • Objective: Patients with inflammatory bowel disease (IBD) have an increased risk of extra-intestinal cancer, whereas its impact on cholangiocarcinoma (CC) remains unknown. The aim of this study was to obtain a reliable estimate of the risk of CC in IBD patients through a meta-analysis of clinical observational studies. Methods: Relevant studies were retrieved by searching PUBMED, EMBASE and Web of Science Databases up to Dec 2013. Four population-based case-control and two cohort studies with IBD were identified. Summary relative risk (RR) and its corresponding 95% confidence interval (CI) were calculated using a random-effects model. Potential sources of heterogeneity were detected using subgroup analyses. Results: The pooled risk estimate indicated IBD patients were at increased risk of CC (RR = 2.63, 95%CI = 1.47-4.72). Moreover, the increased risk of CC was also associated with Crohn's disease (RR = 2.69, 95%CI = 1.59-4.55) and ulcerative colitis (RR = 3.40, 95%CI = 2.50-4.62). In addition, site-specific analyses revealed that IBD patients had an increased risk of intrahepatic CC (ICC) (RR = 2.61, 95%CI = 1.72-3.95) and extrahepatic CC (ECC) (RR = 1.47, 95%CI = 1.10-1.97). Conclusions: This study suggests the risk of CC is significantly increased among IBD patients, especially in ICC cases. Further studies are warranted to enable definite conclusions to be drawn.

  • This study was conducted to draw out prevalence and the risk factors of diabetes mellitus and impaired fasting glucose for adults,(age 30-69). The subjects were 2096 adults, who had regular health examinations between January and December of 1999 at K Hospital in Seoul. The data was analyzed using chi-square test, unpaired t-test and logistic regression. Diabetes Mellitus and impaired fasting glucose were diagnosed by ADA (American Diabetes Association, 1997) criteria. The results were as follows: 1. Mens' prevalence of Diabetes Mellitus was 7.9% and womens' prevalence of Diabetes Mellitus was 3.8%. Mens' prevalence of impaired fasting glucose was 10.4% and womens' prevalence of impaired fasting glucose was 6.5%. Prevalences of Diabetes Mellitus and impaired fasting glucose increased with age. 2. Prevalence of Diabetes Mellitus and impaired fasting glucose of obese subjects (relative body weight>=162) was higher than that of overweight subjects (110<=relative body weight<=119) in men and women. 3. The diagnoses of Diabetes Mellitus and impaired fasting glucose increased with systolic blood pressure and triglyceride. 4. Significant factors associated with diabetes in the logistic regression best gut model were age, relative body weight, systolic blood pressure, triglyceride in men, and systolic blood pressure in women. In conclusion, as age, weight, systolic blood pressure and triglyceride get higher, Diabetes Mellitus and impaired fasting glucose prevalence also increases, porportionally.
