This study was conducted to understand the degree and contents of stress which the mothers of high-risk infants can be experienced from the hospitalization of ICU for their new borns, and thus to offer the basic program to he nursing intervention program for these. Subjects were the 171 mother of hospitalized newborn in NICU of 1 University Hospital in Busan from June, 20, 2001 to September, 15, 2001, who agreed to take part in this study. The instruments used in this study were Parental Stressor Scale:NICU(PSS:NICU) developed by Miles et al. The questionnaire has 4 dimensions and 45 items ; sight and sounds of NICU(5 items), babies' appearance and behavior nursing intervention(19 items), parental role alteration and relationship with their baby(10 items), health team communication(11 items). The data was analysed as average, frequency, Standard Deviation, t-test, ANOVA, Pearson correlation coefficient by use of SPSS/PC+. The results of this study are as follows ; 1. The total perceived stress level score of mothers of high-risk infants was slightly high(3.44±0.71). The highest scored dimension was 'appearance and behavior of the baby'(4.06±0.80), and next were 'relationship with their baby and parental role change'(3.55±0.98), 'sight and sounds of NICU'(3.22±1.01), 'communication with health team'(2.93±0.91). 2. The total perceived stress level score was significantly correlated with birth weight (F=2.35, p<.05). 3. In sight and sounds of NICU, the perceived stress level score was significantly correlated with nursing in the incubator(t=2.28, p<.05) and birth weight(t=2.26, p<.05). In summary, information about physical environment of NICU, birth weight and nursing in the incubator must be included in nursing intervention program of mother's of high-risk infants in reducing the patents stress level. And, it is suggested that there need to find the coping mechanism of mother of high-risk infants.

Purpose: Surgical Site Infection(SSI) is the third most common cause of nosocomial infection, so that it results in serious socioeconomic impact such as extra hospitalization, mortality and health care cost. The aim of this study was to analyses the SSI that based on the degree of wound contamination and patient risk index after general surgery and to generate a reference data for the effective management and reducing SSI. Method: From July, 1999 to June, 2000, 1080 cases which presented with surgical site infection after general surgery at S hospital in chunchon city were included in this study. The data were collected by review of the medical records retrospectively. The collected data, in accordance with the test purpose, is analyzed by SPSS/PC+ program, using real numbers, percentage, $X^2$ test, Pearson's correlation and stepwise logistic regression. Result: The overall wound infection rate was 4.7%(51 cases out of 1,080). The infection rate of clean wounds was 1.4%. Surgical site infection rate for patient risk index scores of 0, 1, 2 and 3 was 1.9%, 8.0%, 13.1% and 20.0%, respectively and increased significantly according to patient risk index(p=.000). Sixteen of the fifty one(31.4%) surgical site infections were found during an outpatient visit after discharge. Multivariate analysis, identified two independent variables : duration of postoperation stay(p=.000), age(p=.037). The most frequent isolated organisms were Pseudomonas aeruginosa(21%) and Staphylococcus aureus(21%). Also Staphylococcus aureus were all MRSA(Methicillin Resistant S. aureus). Conclusion: In this study, SSI was analysed according to the degree of wound contamination and patient risk index after general surgery. The data that obtained from this study is expected that it would be available for surveillance and control of SSI.

Multiple genetic and environmental factors have been reported to play key role in the development of nasopharyngeal carcinoma (NPC). Here, we investigated interactions of XRCC1 Arg399Gln and XRCC2 Arg188His polymorphisms and environmental factors in modulating susceptibility to NPC in Northeast India. One-hundred NPC patients, 90 first-degree relatives of patients and 120 controls were enrolled in the study. XRCC1 Arg399Gln and XRCC2 Arg188His polymorphisms were determined using PCR-RFLP, and the results were confirmed by DNA sequencing. Logistic regression (LR) and multifactor dimensionality reduction (MDR) approaches were applied for statistical analysis. The XRCC1 Gln/Gln genotype showed increased risk (OR=2.76; P<0.024) of NPC. However, individuals with both XRCC1 and XRCC2 polymorphic variants had 3.2 fold elevated risk (P<0.041). An enhanced risk of NPC was also observed in smoked meat (OR=4.07; P=0.004) and fermented fish consumers (OR=4.34, P=0.001), and tobacco-betel quid chewers (OR=7.00; P=0.0001) carrying XRCC1 polymorphic variants. However, smokers carrying defective XRCC1 gene showed the highest risk (OR = 7.47; P<0.0001). On MDR analysis, the best model for NPC risk was the five-factor model combination of XRCC1 variant genotype, fermented fish, smoked meat, smoking and chewing (CVC=10/10; TBA=0.636; P<0.0001); whereas in interaction entropy graphs, smoked meat and tobacco chewing showed synergistic interactions with XRCC1. These findings suggest that interaction of genetic and environmental factors might increase susceptibility to NPC in Northeast Indian populations.

Objectives : Evidence for an effect of rerroductive factors on colorectal carcinogenesis is not yet consistent. Little research has been conducted to investigate whether reproductive factors were associated with colorectal adenomas that are the precursors of colorecta1 cancer, We evaluated the relationships between reproductive factors and the degree of dysplasia of the colorectal adenoma and cancer as colorectal adenoma-carcinoma sequence. Methods : For this study, 241 adenoma cases with histopathologically confirmed incident colorectal adenoma, 76 cancer cases with colorectal cancer and 1677 controls were collected from Our Lady of Mercy Hospital, The Catholic University of Korea, during 1994-1999. Before colonoscopy, information on demographic characteristics, reproductive factors, life style habits and dietary intake were obtained by interviewed questionnaire. Adjusted OR and 95% CI were estimated by using polytomous logistic regression model, Potential confounders that were selected based on the goodness of fit Statistics and interaction between risk factors were considered in this adjustment. The Wald statistic was calculated to test the heterogeneity of the odds ratios for each case. Results .: Postmenopausal women with natural menopause were found to be positively associated with the risk of mild dysplasia adenoma (multivariate-adjusted OR : 2.59, 95% CI=1.1-0.2). Parity was found to be negatively associated with the risk of colorectal lancer (age-adjusted OR : 0.40, 95% CI=0.2-0.9), but did not significantly decrease the risk of colorectal cancer (multivariate-adjusted OR : 0.95, 95% CI=0.3-2.9). Me associations were seen between a9e at menarche, breast feeding, induced abortion, oral contraceptive use, menopausal types, menopausal age or hormone replacement therapy (HRT and the degree of dysplasia of the colorectal adenoma and cancer. However, none of these associations differed' significantly between the degree of dysplasia of the colorectal adenoma and cancer. Conclusions : These findings suggest that postmenopausal women with natural menopause may experience increased risk of mild dysplasia adenorna among colorectal adenoma-carcinoma sequence.

This study aims to explore how the degree of education related to information systems and the Internet literacy affect perceived security risk and how these three variables affect online transaction intention based on the Technology Acceptance Model (TAM). Since using smartphone to purchase necessary products is increasing, the study provided two different cases of using the existing Internet and smartphone to buy products. As a result of an empirical test, the degree of information system education, internet literacy, and perceived security risk had significant effects on online transaction intention mediating perceived usefulness and perceived ease of use. Unlike the expectation, the more people have education related to information systems, the more they have knowledge about hacking or cases of privacy infringement, leading to even more concerns about security, thereby believing the Internet transactions require much effort. The more the education about information system, the more we have concerns about security; therefore, perceived security risk have a positive(+) effect on perceived usefulness not a negative(-) effect. Lastly, while the degree of education related to information systems has relations with the recognition of the usefulness of the Internet transaction, the study showed that there are no relations of recognizing the usefulness and the ease of use of smartphone.

The purpose of this study is to present an appropriate management plan as a supplement to the scientific evidence of the currently operated distancing system for preventing COVID-19. The currently being used mathematical models are expressed as simultaneous ordinary differential equations, there is a problem in that it is difficult to use them for the management of entry and exit of small business owners. In order to supplement this point, in this paper, a method for quantitatively expressing the risk of infection by people who gather is presented in consideration of the allowable risk given to the gathering space, the basic infection reproduction index, and the risk reduction rate due to vaccination. A simple quantitative model was developed that manages the probability of infection in a probabilistic level according to a set of visitors by considering both the degree of infection risk according to the vaccination status (non-vaccinated, primary inoculation, and complete vaccination) and the epidemic status of the virus. In a given example using the model, the risk was reduced to 55% when 20% of non-vaccinated people were converted to full vaccination. It was suggested that management in terms of quarantine can obtain a greater effect than medical treatment. Based on this, a generalized model that can be applied to various situations in consideration of the type of vaccination and the degree of occurrence of confirmed cases was also presented. This model can be used to manage the total risk of people gathered at a certain space in a real time, by calculating individual risk according to the type of vaccine, the degree of inoculation, and the lapse of time after inoculation.

The purpose of the present study was to investigate the use level of display and perceived risk of high school girls according to their attitudes toward fashion. Data were collected through self-administered questionnaires and analyzed by descriptive statistics, $x^2$, ANOVA, and Duncan test. The sample consisted of 390 students at four girls' high schools located in Seoul. The results are as follows : 1. Based on the attitudes toward fashion, respondents were classified into 3 groups, fashion-oriented, fashion-conformed, fashion-retarded. No differences were found in fashion attitudes among and between the groups by residing place. The group having higher interest in fashion spent more expenditure for apparels, and showed the higher interest in display, and highly regarded the needs of display. 2. The more fashion-oriented group showed higher degree of risk perceiving. Especially, they perceived psychological risk, fashionability risk, and social risk highly. And all the three groups perceived opportunity risk most. 3. In general, those who are more sensitive to fashion showed more positive attitude of risk reduction activities.

Based on basic characteristics of urban disasters and their data availabilities in Korea, this study provides risk assessment models which are derived from Cheongju examples. In specific, the application models are confined to fire, facility and escape risk survey results in the paper. For the assessment criteria, major independent variables for the categories of fire include both the frequency levels and the amount of damage. And the degree of facility risk assessment is heavily hinged on both the weighted values of key facilities and their weighted rank-sizes. In the same context, the degree of escape risk assessment is hinged on both the weighted values and the amount of the classification of land. From the empirical configuration, this paper presents that the potential figure of fire risk is relatively higher in the built-up areas within the existing Central Business District where accommodates a number of dilapidated housing units and community-supportive facilities. In contrast, the potential figure of facility and escape risk is higher in both old residential areas and the newly-built apartment complex. In short, the CBD and its neighboring residential areas record a high potential figure in terms of total risk, juxtaposing fire, facility and escape risk all together.
