  • Nanotechnology is one of the critical factors involved in enhancing the sensitivity of serum biomarker detection. To explore the relationship between serum APN, Cystatin C and MMP-9 levels in patients with hypertension during pregnancy and the severity and prognosis of the disease. A total of 75 cases of hypertensive disorder complicating pregnancy (HDCP) patients who were admitted to the hospital from February 5, 2023 to May 9, 2024, were selected as the study group, and 70 healthy pregnant women who were in the same gestational week were selected as the control group. The serum APN, MMP-9 and Cys C levels of pregnant women and HDCP patients with different disease severity were compared between the two groups, and the receiver characteristic curve (ROC) was used to analyze its diagnostic value. The serum APN, MMP-9 and Cys C levels of HDCP patients with different prognosis were compared, and the factors affecting the prognosis of patients were analyzed by Logistic regression. Nanoparticles could aslo enable the sensitive detection and quantification of APN, Cystatin C, and MMP-9 in serum samples, thus increasing the accuracy of the study. The serum MMP-9 and Cys C levels of pregnant women in the study group were significantly increased, and the APN level was significantly decreased (P<0.05). Serum MMP-9 and Cys C levels in patients with pregnancy-induced hypertension, mild preeclampsia, and severe preeclampsia gradually increased (r=0.768, 0.766; P<0.001), and APN levels gradually decreased (r=-0.748, P< 0.001). In the diagnosis of patients with HDCP, the sensitivity, specificity and AUC of APN single diagnosis were 70.00%, 82.67% and 9.848 respectively. The sensitivity, specificity and AUC of MMP-9 single diagnosis were 82.86%, 74.67% and 298.300 respectively. The sensitivity, specificity and AUC of Cys C single diagnosis were 80.00%, 74.67% and 1.301 respectively. There were significant differences in age, BMI, parity, dysthymia, disease severity, APN, MMP-9 and Cys between patients with poor prognosis of HDCP and patients with good prognosis of HDCP (P<0.001). The patient's age, BMI, disease severity, APN, MMP-9 and Cys Cwere all related to HDCP. They were related risk factors of HDCP (P<0.05).

  • Seoul city has high population density as well as high traffic congestion, which are vulnerable to exposure of environmental pollutions caused by car traffic. However, recent studies are only on local regions about road traffic and air pollution or health effect of road traffic on residents. Thus, comprehensive study data are needed in terms of overall Seoul regions. In this study utilized the nitrogen dioxide concentration through the national air pollution monitoring network data, 2012 to 2013. It also divided regions into high and low exposure districts via the Origin destination data developed by the Korea transport institute to quantify and evaluate the effect of transport policies and analyzed a correlation of asthma symptoms with high and low exposure districts through raw data of community health survey from the Korea centers for disease control and prevention. Based on the collected data, the pearson's correlation analysis was conducted between air pollution substance concentration and high exposure district and multiple logistic regression analysis was conducted to determine the effect of traffic environment and factors on asthma symptoms of residents. Accordingly, the following results were derived. First, the high exposure district was higher concentrations of nitrogen dioxide (NO2) as per time compared to those of the low exposure district (p<0.01). Second, analysis on correlation between average daily environmental concentration in the air pollution monitoring network and road traffic showed that nitrogen dioxide had a significant positive correlation (p<0.01) with car traffic and total traffic as well as with truck traffic (p<0.05) statistically. Third, an adjusted odds ratio about asthma doctor's diagnosis in the high and low exposure districts was analyzed through the logistic regression analysis. With regard to an adjusted model 2 (adjusted gender, age, health behavior characteristics, and demographic characteristics) odds ratio of asthma doctor's diagnosis in the high exposure district was 1.624 (95% CI: 1.269~2.077) compared to that of the low exposure district, which was significant statistically (p<0.001).

  • Urban development and densification have led to the Urban Heat Island Effect, in which the temperature of urban space is higher than the surrounding areas, and the intensity is increasing with climate change. In addition, when the city's air temperature rises in summer, low-income, elderly population, and socially vulnerable people who have health problems lack the ability to cope with the elevated heat environment. Therefore, this study aimed to identify the urban heat island area of Seoul through Hotspot analysis, which is a spatial statistics technique, and explored physical environments, demographic and socioeconomic characteristics of urban heat island effect areas using logistic regression models. This study performed urban heat island hotspot analysis using the average air temperatures of the 423 administrative dongs in Seoul. Analysis results identified that the urban heat islands were concentrated in Jung-gu, Jongno-gu, Yongsan-gu, and Yeongdeungpo-gu. Logistic regression analysis results indicated that urban heat island areas of Seoul were affected by residential floor area ratio, commercial facility floor area ratio, overall floor area ratio, impervious surface ratio, and normalized difference vegetation index(NDVI). In addition, as a result of analyzing the vulnerable area of thermal environment considering the demographic and socioeconomic characteristics of the heat island area, urban heat island areas of Seoul were significantly associated with the proportion of low-income elderly living alone. The result of this study provided useful insights for urban thermal environmental design and policy development that could improve the thermal environment for the socially disadvantaged urban population.

  • Background : Complementary and alternative medicine has bee used to cardiovascular diseases. In recent years, many hospitals have tried to integrate complementary and alternative medicine(CAM) with conventional medical approaches for patients with chronic diseases. Recently, the prevalence of the use of traditional Korean medicine(TKM) among patients with chronic diseases, expecially, hemiplegia patients after cerebrovascular accident is increasing in Korea. To date, however, there were only few studies addressing the patients' attitudes, and utilization of TKM, compared to the well-documented escalating use of TKM among consumers in Korea. Objectives : The objective of this study was to analyze the prevalence of TKM use among hemiplegia patients after cerebrovascular accident and to determine what factors affect to use CAM among the patients. The study also aims to provide information on TKM and assist therapy selection among various CAM therapies for hemiplegia patients after cerebrovascular accident within health care system in which both practitioners of TKM and practitioners of modern Western medicine coexisted. Methods : The design of the study was descriptive cross-sectional, and data were collected using a 32-items questionnaire. The subjects were one hundred fifty nine patients with chronic diseases who visited or admitted to health care facilities in a hospital in Seoul Metropolitan city, Korea. Data were analyzed using 'SPSS Statistics 18.0 Network Version(on release 18.0.1 of PASW Statistics)' program. Various statistical methods were used to obtain a profile for participants and the therapies most frequently used by hemiplegia patients of TKM. Logistic regression analysis was employed in order to determine the predicting variables of TKM use. Results : The prevalence of the use of TKM was 51.6%. The most common TKM therapies used by the patients included acupuncture(93.2%), herbal medicine(64.8%), and cupping(37.5%). Results of logistic regression analysis revealed that the variables significantly related with TKM use were gender, marital status, job, No. of visiting health care facilities/week. Conclusions : This study shows that the use of TKM among the hemiplegia patients is relatively high in Korea, this topic should be taken into account in the development of a holistic approach for patients with chronic diseases and an efficient chronic disease management system in Korea.

  • This study is conducted to evaluate the supply effectiveness of the Long-term Secured Public Rental Housing (LSPRH) program implemented by the City of Seoul since March, 2012. To estimate the residential intention of potential applicants for the housing program, two logistic regression models of residential intention are estimated based on the residential characteristics of real residents. The purpose of this model estimation is to find out factors influencing the supply of LSPRH and thus to suggest the ideas for improving the effectiveness of the rental housing program operation. The analysis result shows that financial condition, income level, and public support are the major determinants for selecting LSPRH. It is also revealed that those who are currently living in rental housing or living in a house more expensive than those in nearby areas have higher residential intention for the LSPRH program. The result also presents that some problems associated with the traditional rental housing programs - such as visually recognizable low-quality exterior building design or the concentration of rental housing on limited spots - could be solved by this new type of public housing program. Lastly, one interesting finding different from previous research is that people with the intention to move into either traditional rental housing or LSPRH do not necessarily prefer a more spacious house than their current rental house.

  • Firemen are directly exposed to various harmful chemicals, physical factors and mental stress during rescue and fire-fighting. In fire extinguishing, unstable posture, poisonous gas, dust, high temperature and heavy equipments are possible hazardous factors. The alertness for emergency, shift work, job strain and stress are also possibly hazardous. Therefore, this study aimed to investigate the prevalence of musculo-skeletal symptoms and job stress and to determine risk factors in firemen. This study was carried out in a group of 226 firemen in Busan City, Korea. Standardized Nordic Questionnaire was used to investigate the prevalence of musculo-skeletal symptoms and Psycho-social Well-being Index (abbreviated PWI) was used to investigate the prevalence of job stress. General and occupational characteristics were included education, marital status, alcohol and smoking history, working duration, and work shift system. Body mass index (BMI) scores were calculated by physical examination including height and weight. Concerning musculo-skeletal complaints, the commonest site was neck, and shoulder, lower back, upper back were the next. Complaint site above one area of body was about 80%. From multiple logistic regression analysis, working duration was significant variable in musculo-skeletal symptoms. Odds ratio were 15.4 in working duration. About 16.8% was high risk stress group. From multiple logistic regression analysis, shift work and alcohol drinking were significant variables in PWI scores. Odds ratios were 2.25 in shift work. Accordingly, interventions are needed for health promotion of long term and shift worker.

  • Objective : To evaluate the relationships among sociodemographic characteristics, health behaviors, levels of pros and cons and stages of change in Pap testing for uterine cervical cancer. Methods : A questionnaire survey was performed on 560 randomly sampled people who were assigned to participate in a Pap testing program by the National Cancer Screening Project in 2003' between 25 September and 10 October in Gyeonggi, Korea. Data about the behaviors and intentions of Pap testing, sociodemographic characteristics, health behaviors, and levels of acknowledged benefit (pros) and barrier (cons) for Pap testing was collected. The stages of change were grouped according to behaviors and intentions of Pap testing as passive, active, and relapse. Results : Logistic analysis between the passive and active groups showed that city dwellers, 'high' and 'middle' groups in terms of the individual s health belief, those who had undergone a health examination within the past 2 years, and those who had undergone hormone replacement therapy had a higher odds ratios to be in the active group. As the 'benefit' scores increased and the 'Unnecessity' scores decreased, the probabilities to be in the active group increased. According to the logistic analysis results between the active and relapse groups, those who were 60 years or older, members of the National Heath Insurance, and those who had not undergone a health examination within the past 2 years had a higher odds ratio to be in the relapse group. The 'Benefit' scores were not significant in this relationship. The probabilities of being in the relapse group increased as the Unnecessity and 'Shamefulness' scores increased. Conclusions : In conclusion, health planners should inform women in the passive group of the benefits and necessity of Pap testing. It would be better to reduce the barriers to the active group of undergoing Pap smear. This study might be a useful guide for future planning of Pap testing program.

  • The aim of this study was to find the factors related to smoking-cessation among citizens receiving smoking-cessation clinics' services in a public health center in Daejeon metropolitan city. The study subjects were 2,125 participants registered in "smoking-cessation clinic", public health centers in 2007. Frequency analysis, chi-squared test and multiple logistic regression analysis were used to determine the relationships between the success rate of smoking-cessation and the characteristics. The success rate of smoking-cessation during 6 months was 39.8%. Males had a higher rate than females, and people over 65 years of age had a higher rate than those less than 40 years of age. High blood pressure, drinking of more 2 times per week, regular exercise, CO under 10ppm had significantly relationships with the smoking-cessation rate. The other independent variables had no statistically significance with the smoking-cessation success rate. Logistic regression analysis showed that age, number of nicotine patches used and total consultation times had significantly relationships with the smoking-cessation success rate. The total consultation times showed the highest odds ratio than the other significant factors. This study suggests that regular consultations will be the most effective intervention towards maintaining smoking cessation programs of smoking-cessation clinics in public health centers.

  • Busan city implemented 'taxi transfer discount system' since October 2017 in order to create for new demand taxis. However, due to the low transfer discount amount and limited payment method to prepaid cards, it is difficult to attain the aim. In this study, we investigated the usage status of taxi transfer discount system and the intention to use taxi transfer discount system according to the discount amount level. We established a model of intention to estimate demand of taxi transfer discount using ordinal logistic model. The results of analysis are as following. The critical reason for low usage was to limit taxi transfer discount payment methods to prepaid cards other than post-paid cards which is used for most transportation payment. It was found that the discount rate for taxi transfers was affected in order of payment method, the purpose of the travel, major transportation, frequency taxi use, age, transportation costs, and the discount of taxi transfers. Also, the taxi transfer discount could be expected to increase to 1,550 won based on the price elasticity of demand due to changes in taxi transfer discount rate.

  • The purpose of this study was to determine factors affecting new nurses turnover in Korea. The participants in this study were 227 new nurses who has been working or turnover less than 12 months in fifteen hospitals in B and Y city. Data were collected with structured questionnaires to investigate the socio-demographics characteristics and turnover-related factors, and analyzed using x2test, Fisher's exact test, independent sample t-test, logistic regression with the SPSS win version 18.0 program. The significant factors affecting turnover were age over 26 years(OR=4.00, CI=2.02-7.91), married(OR=6.30, CI=1.21-32.79). On the other hand, mentoring(OR=0.96, CI=0.94-0.99) lowered the probability of turnover. To reduce turnover of new nurses, we need to give special consideration for age of over 26 years and married nurses. Also, there is a need to develop an individualized mentor program.
