Objective : The purpose of the study is to investigate and compare multi-cultural families in terms of mother' s attitude on child-rearing and their children's sensory processing ability. Methods : 19 multi-cultural families and 38 ordinary families were investigated and all the targeted families had children aged 3 to 7 years. Data were collected by a questionnaire asking general characteristics of mother-child; mother's attitude on rearing; and child's sensory processing ability, the Korean-translated version of Short Sensory Profile [SSP], and the Mother nurturing attitude. Data analysis has been done by Descriptive Statistics for subject characteristics and by Mean-Whitney U test for comparison between multi-cultural family group and ordinary family group. Results : There are significant differences between the two family groups in terms of the rearing attitude, especially in sub-item 'refusing(p=.000)'and 'autonomous(p=.000)'. Result of the SSP also indicate significant differences between the two groups in total score(p=.002) and sub-items such as taste/smell sensitivity(p=.004), movement sensitivity(p=.021), underresponsive/seeks sensation(p=.010), auditory filtering(p=.016), low energy/weak(p=.003), visual/auditory sensitivity(p=.029). Conclusion : The results of this study well describe differences between multi-cultural families and ordinary families in maternal child-rearing attitude and sensory processing ability of the children. It is suggested to collect data regarding adaptation of multi-cultural families and their child development through more profound qualitative studies in further.

This study was undertaken in order to estimate the accuracy of disease code of the Korean National Medical Insurance Data and disease the characteristics related to the accuracy. To accomplish these objectives, 2,431 cases coded as notifiable acute communicable diseases (NACD) were randomly selected from 1994 National Medical Insurance data file and family medicine specialists reviewed the medical records to confirm the diagnostic accuracy and investigate the related factors. Major findings obtained from this study are as follows : 1. The accuracy rate of disease code of NACD in National Medical Insurance data was very low, 10.1% (95% C.I. : 8.8-11.4). 2. The reasons of inaccuracy in disease code were 1) claiming process related administrative error by physician and non-physician personnel in medical institutions (41.0%), 2) input error of claims data by key punchers of National Medical Insurer (31.3%) and 3) diagnostic error by physicians (21.7%). 3. Characteristics significantly related with lowering the accuracy of disease code were location and level of the medical institutions in multiple logistic regression analysis. Medical institutions in Seoul showed lower accuracy than those in Kyonngi, and so did general hospitals, hospitals and clinics than tertiary hospitals. Physician related characteristics significantly lowering disease code accuracy of insurance data were sex, age group and specialty. Male physicians showed significantly lower accuracy than female physicians; thirties and fortieg age group also showed significantly lower accuracy than twenties, and so did general physicians and other specialists than internal medicine/pediatric specialists. This study strongly suggests that a series of policies like 1) establishment of peer review organization of National Medical Insurance data, 2) prompt nation-wide expansion of computerized claiming network of National Medical Insurance and 3) establishment and distribution of objective diagnostic criteria to physicians are necessary to set up a national disease surveillance system utilizing National Medical Insurance claims data.

This study was performed to investigate LBP(low-back pain) prevalence rate and its related factors inphysical therapists. A self-administered questionnaire survey was conducted to 522 physical therapists in Daegu and Gyeongsangbuk. The LBP prevalence rate for recent 6 months was $61.7\%$. According to age, the prevalence rate was highest in the group aged 24 or less for both male and female physical therapistis. For male physical therapists , it was higher in smokers and drivers, but for female ones, it was not in a significant relationship with smoking and driving. According to work experience, the prevalence rates of those who had been working for less than one year were the highest, and those who had been working at hospitals and clinics were $69.1\%$, significantly high. According to therapy techinque, the prevalence rate related ti PNF was $71.6\%$, the highest and to occupational therapy was $34.3\%$, the lowest. According to working environment for six months, in both male and female physical therapists. LBP prevalence rate was in a statistically significant relationship with work hours during the day, night and weekend duties, repetitive works, motions that bend or twist the waist, the number of patients per day, the number of time to help patients per day, the number of time to carry medical equipment per day and the length of time to work standing. The rate was also higher when physical therapists fekt nire stress from their work. According to the result of multiple logistic regression analysis, male was in a significant relationship with work experience and motions that bend or twist the waist and female was in a significant relationship with work hours during the night and weekend duties, the number of time to help patients per day, motions that bena or twist the waist, actions taken to protect the waist. As for the developmental pattem of LBP in the group of physical therapists with LBP for six moths, $15.7\%$ of them had LBP for first time, $42.3\%$ had recurred LBP, and $42.0\%$ had chronic LBP. As for the causes of LBP, $51.7\%$ said that it was because they worked in the same posture for a long time, and as for how to treat LBP, 48.8% said that they treated themselvs or got help from their co-wokers. The results presented above suggest that physical therapists are exposed to high risk of LBP caused form occupational activities. Therefire, it is necessary to improve working environment to reduce the occurrence of LBP and to develop education programs for preventing the occurrence and recurrence of LBP.

This study evaluated the concentrations of urinary metabolites of polycyclic aromatic hydrocarbons (PAHs) in industrial waste incineration workers. The effect of genetic polymorphisms of xenobiotic metabolism enzymes on urinary concentration of PAH metabolites was assessed. And, aromatic DNA adduct levels were also determined in total white blood cells. Fifty employees were recruited from a company handling industrial wastes located in Ansan, Korea: non-exposed group (n=21), exposed group (n=29). Sixteen ambient PAHs were determined by GC/MSD (NIOSH method) from personal breathing zone samples of nine subjects near incinerators. Urinary 1-hydroxypyrene glucuronide (1-OHPG), a major pyrene metabolite, was assayed by synchronous fluorescence spectroscopy after immunoaffinity purification using monoclonal antibody 8E11 (SFS/IAC). Multiplex PCR was used for genotyping for GSTMI/TI and PCR-RFLP for genotyping of CYP1A1 (MspI and Ile/Val). PAH-DNA adducts in peripheral blood WBC were measured by the nuclease P1-enhanced postlabeling assay. Smoking habit, demographic and occupational information were collected by self-administered questionnaire. The range of total ambient PAH levels were 0.00-7.00 mg/㎥ (mean 3.31). Urinary 1-OHPG levels were significantly higher in workers handling industrial wastes than in those with presumed lower exposure to PAHs (p=0.006, by Kruskal-Wallis test). There was a statistically significant dose-response increase in 1-OHPG levels with the number of cigarettes consumed per day (Pearson correlation coefficient=0.686, p<0.001). Urinary 1-OHPG levels in occupationally exposed smoking workers were highest compared with non-occupationally exposed smokers (p=0.053, by Kruskal-Wallis test). Smoking and GSTMI genotype were significant predictors for log-transformed 1-OHPG by multiple regression analysis (overall model R²=0.565, p<0.001), whereas smoking was the only significant predictor for log-transformed aromatic DNA adducts (overall model R²=0.249, p=0.201). Aromatic DNA adducts was also a significantly correlation between log transferred urinary 1-OHPG levels (pearson's correlation coefficient=0.307, p=0.04). However, the partial correlation coefficient adjusting for Age, Sex, and cigarette consumption was not significant (r=0.154, p=0.169). The significant association exists only in individuals with the GSTMI null genotype (pearsons correlation coefficient=0.516, p=0.010; partial correlation coefficient adjusting for age, sex, and cigarette consumption, r=0.363, p=0.038). Our results suggest that the significant increase in urinary 1-OHPG in the exposed workers is due to higher prevalence of smokers among them, and that the association between urinary PAH metabolites and aromatic DNA adducts in workers of industrial waste handling may be modulated by GSTMI genotype. There results remain to be confirmed in future larger studies.

Objectives: Cardiovascular disease is one of the main causes of death and morbidity in Korea. In this study, the prevalence and incidence of developing hypertension in a male-workers' cohort were investigated during 3-years follow-up with a view to find the risk factors that affected the development of hypertension. Methods: Among the 5,374 people who participated in a routine health check up, 3,852 people with normal blood pressure and who had no history of hypertension were prospectively followed up for 3 years. The classification of hypertension was based on the JNC7 report (the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure). Life style factors and underlying diseases that were related to the risk factors of hypertension were collected by using a self-report questionnaires via the internet. Results: The prevalence of hypertension was 28.3% (1,520/5,374) at the first screening (2001). It was found that the incidence in 2004 of hypertension for the follow-up subjects (3,711) who had normal blood pressure in 2001 was 7.6 per 100 person-year. Multiple logistic regression analysis of the variables related to the risk factors of hypertension was carried out. The relative risks were 1.037 (95% CI=1.022-1.053) as the age increased 1 year and 1.039 (95% CI=1.023-1.055) as the body mass index increased $1kg/m^2$. The relative risk for the prehypertensive group was 2.501 (95% CI=1.986-3.149) compared to the normotensive group. These results showed that age, body mass index and the baseline blood pressure were significantly related to the incidence of hypertension. Conclusions: The incidence of hypertension was 7.6 per 100 person-year during follow-up. It was concluded that the risk factors for developing hypertension in the short-term were age, BMI, and prehypertension; Especially, this showed that it is necessary for prehypertensives to manage their body weight and blood pressure to prevent hypertension in middle-age by modifying their life style.

Objectives: This study was carried out to identify relation of health care utilization due to skin disease(ICD-10, L00-L99) and characteristics(sex, age, exposure status, type of industry, size of enterprise) of workers. Methods: We made new database composed of 30,536 workers' health examination results in one specific health examination institute in Inchon and data of medical insurance utilization due to skin disease in 4 medical insurance associations for enterprise from January, 1995 to December, 1997 And we analyzed determinants of health care utilization due to skin disease of workers. Results: Among 30,536 study subjects, 8,837(28.9%) workers and 4,181 (13.7%) workers utilized medical insurance due to total skin disease(ICD-10, L00-L99) and contact dermatitis(ICD-10, L23-L25), respectively. Female workers(p<.001), workers exposed to organic solvents(p<.05), workers if manufacturing industries(p<.05, p<.01, respectively) and in large scale enterprises(p<.001) utilized more medical insurance due to total skin disease and contact dermatitis than male workers, workers not exposed to organic solvents, workers in non-manufacturing industries and small scale enterprises. With multiple logistic regression analysis, significant explanatory variables affecting workers' medical utilization due to total skin disease and dermatitis and eczema(ICD-10, L20-L30) in total workers were sex, age, specific chemicals and size of enterprises. And age, type of industries, organic solvents, specific chemicals and size of enterprises were significant explanatory variables related to medical insurance utilization due to dermatitis and eczema and contact dermatitis in male workers. Conclusion: From the above results, we found that workers exposed to organic solvents utilized more medical insurance due to skin disease than workers not exposed to. And, comparing to workers in large scale enterprises, workers in small scale enterprises may have unmet medical care utilization due to skin disease. Therefore we have to establish counterplan to manage occupational skin disease of high risk group(organic solvent exposure group) and to satisfy unmet medical care utilization of workers in small scale enterprises.

Objectives: The purpose of this study was to determine whether the disabled have worse access to primary care than the non-disabled. Methods: We used the National Disability Registry data and the National Health Insurance data for the calendar year 2003, and we analyzed 807,380 disabled persons who had been registered until December 2001 and we also analyzed 1,614,760 non-disabled persons for nine ambulatory care sensitive conditions (ACSCs). The rates of physician visits and hospitalizations for the patients with ACSCs were compared between the disabled and the nondisabled. Multiple logistic regression analysis was used to evaluate the association between medical care utilization and disability and to assess the association between hospitalization and the number of physician visits while controlling for potential confounders. Results: The numbers of physician visits per 100 patients were $0.78{\sim}0.97$ times lower for the disabled than that for the non-disabled with five of nine ACSCs. The numbers of hospitalizations per 100 patients were $1.16{\sim}1.77$ times higher for the disabled than that for the non-disabled with all the ACSCs. While the ORs of a physician visit for the disabled were significantly lower than that for the non-disabled with all the ACSCs (OR: $0.44{\sim}0.70$), and the ORs of hospitalization for the disabled were significantly higher (OR: $1.16{\sim}1.89$). The lower physician visit group (number of physician visits ${\leq}$1) was more likely to be hospitalized than the higher physician visit group (number of physician visits ${\geq}$2) (OR: $1.69{\sim}19.77$). The effect of the physician visit rate on hospitalization was larger than the effect of disability on hospitalization. Conclusions: The results suggest that the disabled were more likely to be hospitalized for ACSCs due to their lower access to primary care.

Objectives : The purpose of this study was to examine the relationship of oral health behavior factors to oral health promotion behavior in dental hygiene students and nonhealth-related majors, to identify factors affecting their oral health promotion behavior and ultimately to provide information on the oral health promotion of college students and behavioral factors related to that. Methods : The subjects in this study were three-year-course dental hygiene students and two-year-course nonhealth-related majors in G college located in the city of Gwangju. A self-administered survey was conducted for 11 days from September 9 to 19, 2009, and the answer sheets from 473 respondents were analyzed. To look for connections between their major and the characteristics of their oral health promotion behavior, t-test was utilized, and t-test and one-way ANOVA were carried out to find out the relationship oral health promotion behavior by general characteristics. Besides, multiple regression analysis was employed to grasp factors affecting oral health promotion behavior. Results : Among the subfactors of oral health promotion behavior, the dental hygiene students statistically significantly outdid the nonhealth-related majors in thorough post-meal toothbrushing(p<0.01), toothbrushing method(p<0.001), use of fluorine-containing dentifrice(p<0.001) and good nutrition(p<0.05). But the latter statistically significantly outperformed the former in use of fluorine-containing rinse(p<0.001) and limited sugar intake(0<0.05). Regarding variables affecting oral health promotion behavior, the age group, whether to get a dental checkup over the last year and whether to use oral hygiene supplies were identified as the variables to impact on oral health promotion behavior. Specifically, the age group(dental hygiene students) and the get a dental checkup over the last year(nonhealth-related majors) had a greater impact. Conclusions : To promote the oral health of college students, comprehensive oral health education should be provided, which covers the importance of dental checkup, recommendation for the use of oral hygiene supplies, etc. Specifically, oral health education should be offered as one of general education courses in order for nonhealth-related majors to get into sound life habits and improve their oral health promotion behavior. To make it happen, required institutional measures should be taken.

The purpose of this study was to construct and test a structural equation model for college student's gambling behavior. A structured questionnaire was completed by 246 college students to analyze the relationships between perspective factors(irrational gambling belief), psychological factors(depression, anxiety), social factors(parental monitoring, parental support, friend support), self-control and gambling behavior. The moderating effects of gender, friends and family's gambling behaviors were examined. The data were analyzed using SPSS 21,0 and AMOS 20.0 programs. Self-control and psychological factors directly affected the college student's gambling behavior, while perspective factors and social factors affected it indirectly. The model fit indices of the modified model were suitable for the recommended levels. The overall study findings suggest the need to develop a gambling prevention program for college students that reinforces self-control, parental monitoring and support, and friend support while reducing irrational gambling belief, depression, and anxiety. An approach that considers gender and a development of a group counseling program for family or friends are also required.

This study aimed to investigate the levels of Obstructive Sleep Apnea (OSA), health behavior and sleep quality and to examine the predictors of OSA in patients with ischemic cardio-cerebrovascular disease. 141 patients who were admitted to the vascular unit were recruited and surveyed using structured questionnaires. Saturation of Peripheral Oxygen (SpO2) was measured at three time points using a pulse oximeter. Data were analyzed using SPSS/WIN 20.0. The mean age of the subjects was $64.4{\pm}11.1$ years and 61% was men. The 21.3%(n=30) of the subjects were classified as high-risk for OSA by the cut point and 71.6%(n=101) had low sleep quality. OSA high-risk group showed significant difference in SpO2 in the middle of sleep (p=.006) and at the end of sleep (p=.004) compared to the low-risk group. Multiple logistic regression analysis showed that perceived frequent snoring, smoking, obesity, lack of exercise among health behavior were found as predicting factors on OSA. OSA or persistent snoring should be recognized as a cardiovascular risk factor in the cardiovascular nursing practice. In addition to early treatment of OSA, education and counseling should be provided to patients and their family for prevention of secondary recurrence.
