  • PURPOSES : This study is to develop ISM for potential risk factor in School Zone. METHODS : Based on the literature review, the Analytic Hierarchy Process (AHP) has been used most widely. However, it is difficult to apply in practice because the AHP results have the characteristics of the independence between each element and the interlayer can not explain the interrelationship. The Network Analysis Process (ANP) is possible to analyze the relationship between the elements and the network through the feedback. But, the reliability of the analysis fall because of complicated pair of comparison, also it is difficult to solve the super matrix. In this study, the complicated relationship between each element is inquired through the Interpretive Structural Modeling (ISM). RESULTS : The methodology of ISM is developed to remove the children's potential risk factors in school zone. CONCLUSIONS : It is possible to remove the children's potential risk factors from low level to high level step by step and improve safety. Through this, risk factors can be removed from the low-level, and upper-level will automatically improve.

  • Minority populations in the United States have a higher prevalence of non-insulin-dependent diabetes mellitus (NIDDM) and more persons die of the disease than white persons. This study was to review and compare risk factors and prevalence rates of NIDDM in African Americans, Hispanic s, Korean Americans and Native Americans in the United States. The risk factors of NIDDM, including family history of diabetes, obesity, physical inactivity, diet and age, were reviewed in the minority populations. Risk factors such as obesity, physical inactivity and family history of diabetes occurred to a greater extent in some minority populations than in the white population. Diabetes should be treated as a public health problem for minority populations. Due to the increase of older populations and the increased prevalence of obesity and sedentariness, NIDDM in minorities is nearing epidemic proportions. Good diet and regular exercise can reduce the incidence of NIDDM but an understanding of the cultural aspects of diabetes is imperative in order to provide adequate community health education programs because those programs involve diet and behavior changes, characteristics that are often culturally determined. In summary, it is important to plan a community health education program targeted on NIDDM in a culturally adapted manner that will be received with both comprehension and acceptability. In particular, the program for high-risk populations should be stressed so to prevent diabetes. Preventive approaches to diabetes should be considered because they can be both therapeutic and cost effective.

  • Background and purpose : Stroke is one of the most deadly diseases and a leading cause of disability. Lipids confer an increased risk for cardiovascular morbidity and mortality. In spite of many studies on the relationship between stroke and lipids, their relationship is not clear. This study was undertaken to determine whether lipids were associated with stroke. Method : We compared the components of blood lipids between stroke patients group (n=217,Cases), non-stroke control group (n=160, Controls) and healthy control group without hypertension, diabetes mellitus, ischemic heart disease, or hyperlipidemia (n=140, Normals). These data were statically analyzed by general linear models and binary logistic regression analysis to get each adjusted odds ratio. Result : The results were as follows. The blood levels of total cholesterol (T-Chol), triglyceride (TG) and low density lipoprotein cholesterol (LDL-Chol) were significantly higher in patients of ischemic stroke, while the blood levels of T-Chol and LDL-Chol were significantly lower, and the blood levels of TG significantly higher in patients of hemorrhagic stroke. The blood level of high density lipoprotein cholesterol (HDL-Chol) was significantly lower in all cases. Conclusion : These results suggest that high TG and low HDL-Chol may be risk factors of hemorrhagic stroke and ischemic stroke, high T-Chol and LDL-Chol may be risk factors of ischemic stroke, and low T-Chol and LDL-Chol may be risk factors of hemorrhagic stroke in Koreans.

  • 유류를 포함한 위험 유해물질(Hazardous and Noxious Substances : HNS, 이하 HNS)의 물동량이 증가하는 추세에 있음에도 불구하고 우리나라에서는 HNS 해상운송 중에 일어난 사고의 분석과 위험에 관한 연구가 미진하다. HNS는 형태와 종류가 다양하고, 사고발생 시 피해가 심각하게 나타나기 때문에 사고에 대한 위험도 분석과 저감방안 모색이 필요하다. 본 연구는 ETA를 통해 국내에서 발생하고 있는 HNS 해상운송사고의 전개과정을 분석하여 사고유형과 특징을 고찰하고, 시나리오별 확률과 인명피해를 산출하여 F-N curve로 표현함으로써 위험도를 평가한다. 또한 Risk Matrix를 이용하여 고위험군 시나리오를 선정하여 국내에 적용 가능한 현실적인 사고 저감방안을 모색한다. 연구의 결과는 충돌사고의 발생확률이 가장 높은 반면 인명위험도는 발생확률이 낮은 질식, 침몰, 폭발의 사고유형이 높은 것으로 나타났다. 이러한 인명피해를 줄이기 위해서는 기본적으로 선내에서 안전수칙 및 작업절차를 준수하는 것으로도 효과를 얻을 수 있다.

  • Aim: The risk factors mostly strongly associated with gastric cancer are gastric bacteria Helicobacter pylori and diet. Using a case-control study among residents in Jinan, we examined the association between the salt taste and gastric cancer according to H. pylori infection, smoking and histological type as well as tumor site. Methods: This population-based case-control study included 207 cases and 410 controls. Data on potential risk factors of gastric cancer were obtained by interview of cases and controls with a questionnaire, salt taste preference was measured for all subjects, and IgG antibodies to H. pylori were applied to assess infection. Risk measures were determined using unconditional logistic regression. Results: The proportions of salt taste at intervals of 1.8-7.2 g/L and ${\geq}7.2$ g/L were significantly higher in cases than controls, with ORs of 1.56 (1.23-3.64) and 2.03 (2.12-4.11), respectively, subjects with high salt intake having an elevated risk for gastric cancer when infected with H. pylori. Significant modification by smoking and tumor site was observed across the different measures of salt intake, the highest salt taste showed higher cancer risk in ever smokers or with non-cardia cancers. Conclusion: Our study supports the view that high intake of sodium is an important dietary risk factor for gastric cancer, with a synergistic effect found between salt and H.pylori and smoking, dependent on the tumor site.

  • This study was conducted to recognize the need for diet and nutrition education to correct body-shape and eating habits that lead to eating disorders in college students. The relationship between diet and obesity was confirmed. Approximately 405 (male 46.4%, female 53.6%) students were evaluated by questionnaire in September 2014. The statistical program SAS (ver. 4.3) was used to evaluate the Chi-squared, F and T-value. The correlation between eating disorder risk and eating habits was evaluated by Pearson's correlation. Body type recognition was classified into nine steps up the body fatty (9) to skinny (1) to show their body. Eating disorder risk (KEAT-26) was composed of F1 (attachment factors for weight loss), F2 (attachment factors for binge eating, and food), and F3 (adjustment factor to eating their will. The risk of eating disorders in male 73.4% of low risk, in female 61.3% (p<0.05). According to body mass index, underweight groups recognized in the normal weight (53.7%), normal weight group was in overweight (29.1%) (p<0.001). According to body-type, the overweight group had a higher risk of eating disorders (68.2%). The KEAT-26 showed that the overweight and obese group were high-risk in F1 & F2, while the underweight group was high-risk in F3 (p<0.001). Recognized overweight showed the dangers of eating disorders, proper recognition of body-type and body mass index required. Tendency to seek a balanced diet was associated with eating disorders, no-imposed adequate diet for nutritional education would be made. Proper nutrition education for males is needed depending on the increased incidence of male eating disorders.

  • Northeastern India is a major nasopharyngeal carcinoma (NPC) high risk-area although the rest of the country has very low incidence. A case-control study of 105 NPC cases and 115 controls was conducted to identify the potential risk factors for NPC development in this region. Information was collected by interviewer about socio-demographic characteristics, cigarette smoking, alcohol consumption, dietary history, occupational history, and a family history of cancer. Epstein-Barr viral load was assayed from the blood DNA by real time PCR. Associations between GSTs genotypes, cytochrome P450 family including CYP1A1, CYP2E1 and CYP2A6 polymorphisms and susceptibility to relationship between the diseases were studied using PCR-RFLP assay. Results indicate that Epstein-Barr virus load was significantly higher in patients compared to controls (p<0.0001). Furthermore, concentration of blood EBV-DNA was significantly higher in advanced stage disease (Stage III and IV) than in early stage disease (Stage I and II) (p<0.05). Presence of CYP2A6 variants that reduced the enzyme activity was significantly less frequent in cases than controls. Smoked meat consumption, exposure to smoke, living in poorly ventilated house and alcohol consumption were associated with NPC development among the population of Northeastern India. Thus, overall our study revealed that EBV viral load and genetic polymorphism of CYP2A6 along with living practices which include smoked meat consumption, exposure to smoke, living in poorly ventilated houses and alcohol consumption are the potential risk factors of NPC in north eastern region of India. Understanding of the risk factors and their role in the etiology of NPC are helpful forpreventive measures and screening.

  • The purpose of this study was to clarify the dynamic relationships among risk factors of arteriosclerosis and to develop and examine a model which could explain this relationship clearly. Data were collected from medical records of 400 male clients who visited a university hospital located in Inchon for physical examinations, from May 1996 to December 1996. Data were analyzed using the LISREL (Linear Structural Relationship) 8 program. To test the fitness of the hypothesized model, chi-square, RMSR (root mean square residual), GFI (goodness of fit index), CN (critical number) and Q-plot were used. Most of the fitness measurements, except the chi-square showed that the hypothesized model complimented the real data. According to the results, there were trends that obesity and hyperlipidemia were prevalent in heavier smokers, higher alcohol intakers, and groups who excercised less. Also, hypertension was more prevalent in older age, higher alcohol intaker, and higher serum lipid level groups. In contrast to the hypothesis, alcohol intake did not significantly affect serum lipid levels. This might be due to the serum lipid measurements (total cholesterol and trigryceride) used in this study to estimate hyperlipidemia. The direct effect of smoking on hypertension was not significant. However, the total effect of smoking on the hypertension was significant since indirect effects of smoking on hypertension, such as obesity and hyperlipidemia, were significant. The total effect of obesity on hypertension was significant since the indirect effect of obesity on hypertension via hyperlipidemia was significant, although the direct effect of smoking on hypertension was not significant. The degree of explaining hyperlipidemia with smoking, exercise, and obesity was high (60%), however, the degree of explaining obesity with age, smoking, alcohol intake, and exercise was very low (7%). On the basis of these results, high risk factors of arteriosclerosis such as hypertension, hyperlipidemia, or obesity are either directly or indirectly correlated each other. Therefore, it is difficult to predict outcomes for increasing or decreasing the risk factors by simply modulating a factor. Smoking, alcohol, and exercise both directly and indirectly affected major risk factors of arteriosclerosis. Therefore, correcting these variables is required to decrease risk factors. Finally, the relationship among other risk factors which have been known to be related with arteriosclerosis (diet, stress or hereditary) should be clarified in further studies.

  • Purpose: Nutritional status and support in critically ill patients are important factors in determining patient recovery and prognosis. The aim of this study was to analyze the early nutritional status and the methods of nutritional support in critically ill patients with acute poisoning and to evaluate the effect of nutritional status on prognosis. Methods: A retrospective study was conducted in tertiary care teaching hospital from January 2018 to December 2020. in an emergency department of university hospital, 220 patients who were stayed more than 2 days of poisoning in intensive care unit were enrolled. Results: 155 (70.5%) of patients with acute poisoning had low-risk in nutritional risk screening (NRS). Patients with malignancy had higher NRS (low risk 5.2%, moderate risk 18.5%, high risk 13.2%, p=0.024). Patients of 91.4% supplied nutrition via oral route or enteral route. Parenteral route for starting method of nutritional support were higher in patients with acute poisoning of herbicide or pesticide (medicine 3.2%, herbicide 13.8%, pesticide 22.2%, p=0.000). In multivariate logistic regression analysis, herbicide or pesticide intoxication, higher risk in NRS and sequential organ failure assessment over 4.5 were affecting factor on poor recovery at discharge. Conclusion: NRS in patients intoxicated with herbicide or pesticide were higher than that in patients intoxicated with medicine intoxication. Enteral nutrition in patients intoxicated with herbicide or pesticide was less common. Initial NRS was correlated with recovery at discharge in patient with intoxication. It is expected to be helpful in finding patients with high-risk nutritional status in acute poisoning patients and establishing a treatment plan that can actively implement nutritional support.

  • This study is aimed to find a control factor for the marine casualty of fishing vessel by using the risk quantitative method of marine casualty, and sequentially timed event analysis for the reason finding. The result is that collision, sinking, and capsizing took high risk need to be strongly controlled. And the accident reason and control factors distinguished are as follows. The 82.2% of collided fishing vessels have negligence of look out as a immediate cause, while it was judged that underlying causes were the characteristics of vessels and fishing method, lack of suitable complement, fatigue, the prejudice or ignorance on steering and sailing rules. So the control factors are; firstly needs educational control measures and in terms of systemic control approach expand the range of the certificate of competency more smaller tonnage.
