There is very high preference for the firms to locate in the Capital region, the City of Seoul and its surrounding areas, which inevitably meets diverse types of regulations to prevent over-concentration in Korea. In order to suggest an urgent need to reform these regulations, the demand for knowledge-based industries is estimated. A legit model is employed to estimate the demand of relocation of the current firms based on a survey conducted in 2001. A logistic curve is used to forecast the demand of new start-ups in Korea. The lands for industrial use only are estimated as many as 2.1 million~3.9 million pyung(1 pyung=3.3$m^2$) in nation-wide. Considering affiliate facilities and infrastructures, 3.1 million~5.9 million of industrial area should be developed in Korea for next five years. Since the rents are very high and the available land is short in the southern parts of Seoul, where most knowledge-based firms locate right now. Many firms have considered relocating on any other places where there exist a plenty of lands available and cheaper rents and cheaper wage rates, but still not far away from Seoul so that they could obtain new advanced information, skilled labors, venture capitals, and high quality of producer services. The Capital region, especially Gyeonggi and Incheon, is the only place to meet those conditions in Korea.

Objective: Despite the increasing number of female participation in employment, blue-collar women have been exposed to higher health risk. This study is to describe the prevalence of chronic diseases, health behaviors, and medical service utilization of female blue-collar workers. Methods: Data were derived from the 2001 Korea National Health and Nutrition Survey (KNHANES). The sample was made up of 37,108 male and female participants aged 20 or over selected nation-wide by probability sampling from Korea. This study applied the logistic regression for nominal variables such as disease prevalence and health behaviors and with the regression for continuos variables such as the length and costs of medical services. Results: In general, women's prevalence of chronic illness and uncured rate were significantly higher than male, and especially female blue-collar workers had the highest prevalence, uncured rate, unhealthy status, and perceived stress. However, the medical care cost was the lowest in female blue-collar workers. Conclusions: The findings suggest that female blue-collar workers were more likely to experience health problems, and that despite the highest health risk, health service is not effectively utilized, and health policy maker should take consider of special status of female blue collar workers who are in health inequality.

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.

In Korea, changes in children's diet patterns accelerate their physical growth and development: frequent snacking has been presumed to be a major cause of increasing dental caries. The present study attempts to clarify the relationship between the physical development of growing children and their tooth decay. For this purpose, 632 six-grade children in 4 elementary school located in Urban(Seoul) and Rural(Po-gok, Yang-In) were classified into three groups based on the Weight Length Index(WLI), known to reflect the nutritional conditions of school-age children, and the relationship was analyzed between each group and the variables considered to be related with dental caries. The result is as follows: The average weight and height of the male is $44.88{\pm}10.89$ kg, $148.49{\pm}7.33$ cm and female is $43.35{\pm}9.60$ kg, $149.23{\pm}6.73$ cm, respectively, which are in the similar level with the Korean Physical Standard. The classification of the children by the WLI reveals a relatively high distribution of over-weighted child ren - 212 persons, 335% of the entire population. The DMFT Index was a little high in the rural area(3.15 teeth in urban and 3.31, in rural). Among the groups of children classified by the WLI, the over-weight group have the highest DMFT index(3.69 teeth). The relationship between the frequency of taking in basic nutrients and the DMFT index is also found: the relationship is not evident in case of the foods containing rich calcium, protein, as well as fruits and vegetables. But, in the protein-rich food, higher frequency of its intake means significantly lower DMFT index in the normal-weight group of the urban children. In case of carbohydrate, higher frequency of its intake means significantly higher DMFT index in all the groups of the rural children. The DMFT index has some correlations with the relevant variables: the index has a positive correlation with the frequency of snacking, and a negative correlation with the economic status. That is, the higher the frequency of snacking is, and the lower the economic status is, the higher the DMFT index may be. In the logistic multiple regression analysis conducted with the presence of DMFT as a dependent variable, only the frequency of tooth brushing is turned to be a variable affecting the presence of either decayed, missing, or filled teeth. Based on the above result, the variables affecting the DMFT index are a time spent on eating, frequency of intake of protein and carbohydrate for a week, frequency of snacking, regular dental check-ups, preventive behaviors for oral health(fluoride gargling, tooth brusing after each meal, proper tooth brushing method). These variables have a relationship with the DMFT index, but the degree is somewhat different between the groups classified either by the region or by the WLI. Therefore, appropriate nutrition management should be conducted according to the individual's nutritional conditions when the services like nutritional education are provided based on the closely-examined characteristics of each target group. And, at the same time, oral health education should be strengthened, and its importance should also be emphasized so that people can pay attention to their own oral health.

Objective: After introduction of the Elderly Long Term Care Insurance, number of geriatric hospitals increased greatly. However, few studies were conducted on the satisfaction of the patients of the geriatric hospitals especially on the intention to reuse geriatric hospitals. Methods: The current study modified Sheth's consumption value model, useful for the development of an effective marketing strategy for geriatric hospitals, and tested it in Korean circumstances. The survey was conducted at two municipal hospitals and three private hospitals in Seoul and Gyeonggi Province between August 1 and September 30 of 2012. Data were collected from 472 inpatients who are 60 years or older. The structured research tool was developed and distributed. Factor analysis and hierarchical logistic regression analysis were conducted using SPSS(version 14.0) Results: The result of the research suggested that the satisfaction on rehabilitation services, which is a functional value, among the consumption values was the strongest factor on the intention to reuse geriatric hospitals. Impression of high-end luxury, reliability of care, and outside locus of control on health followed. Conclusion: It is recommended that geriatric hospitals ought to improve rehabilitation programs, facilities, and equipments and enhance kindness of staff to encourage intention to reuse geriatric hospitals.

This study examined the mental health status (depression, cognitive impairment and dementia) and its association with the related factors in the elderly people who were admitted from long-term care insurance. The study subjects were 1,488 people (male 740, female 748) aged over 70 years of age who had been recognized for long-term care insurance services in the years 2011~2014 from the National Health Insurance Corporation. The data collected from the National Health Insurance Corporation set forth a lifestyle questionnaire, itemized health screening tests, and long-term care as recognition data for research purposes. As a result, depression, cognitive impairment, and dementia of subjects increased significantly with age. As a multiple logistic regression result, the risk ratios of depression, cognitive impairment, and dementia, which indicated the mental health status, were significantly higher in women than in men, in the lower body weight group than in the overweight group, in the smoking group than in the non-smoking group, and in the drinking group than in the non-drinking group. These results suggest that the mental health status (depression, cognitive impairment, and dementia) of subjects decreased with increasing age, particularly the group with poor health related behaviors, such as smoking, drinking, and regular exercise, indicating that the mental health condition is lower than in the good group.

This study conducted a chi-square test and a logistic regression analysis by not only using a investigation data of discharged patients with damages from 2004 to 2006, but also using a census and a research data on the actual condition from health care system. The result follows; First, the centralization of medical utilization of operation patients is becoming apparent, centrally the capital area. To improve this, a policy that can not only provide medical centers and sickbed, but also improve the quality of local medical treatments for the localization of medical treatments. Second, propelling localization policy of certain diseases for the localization of medical utilization is needed as the rate of non-residential of operation patients that have diseases of the eye and adnexa, or cancers is high. Third, a localization policy for patients with damages is needed as the rate of treatments in other regions of operation patients with industrial accidents is increasing day by day.

This study was performed to determine the levels of physical function (ADL, IADL) and to reveal its association with the related factors in the elderly people. The study subjects were 1,756 (male 872, female 884) people aged over 70 who received medical check-ups and long-term care services between 2009 and 2012 from the National Health Insurance Corporation. As a result, the distribution of impaired ADL and IADL increased significantly with age. Logistic regression showed that the risk ratio of impaired ADL was increased significantly in the following groups: female, urban, low weight, stroke history group, smoking, alcohol drinking, and not regular exercise group. The risk ratio of an impaired IADL were increased significantly in the group of females, low weight, smoking, alcohol drinking. On the other hand the risk ratio of an impaired ADL and IADL was similar in each age group. As above results, the levels of ADL and IADL in the study subjects are closely related to the socio-demographic characteristics and health related behaviors. In particular, they suggested that the levels of ADL and IADL were lower in the poor group of the health-related behaviors, such as smoking, alcohol drinking, and regular exercise.

Background: While the perinatal outcomes of active maternal smoking are well documented, results of the effects of environmental tobacco smoke (ETS) exposure during pregnancy are inconsistent. We aimed to examine the effect of ETS exposure, assessed by maternal hair nicotine levels at $35^{th}$ week of gestation, on birth weight and the risk of small for gestational age (SGA) and low birth weight (LBW). Materials and Methods: A total of 871 non-smoking healthy pregnant women were recruited by one Korean hospital between 1 October 2006 and 31 July 2007. Hair samples were collected and anthropometric questionnaires administered at $35^{th}$ week of gestation. The primary outcome was birth weight and secondary outcomes were the risk of babies being SGA and LBW. Results: Log-transformed hair nicotine concentrations were inversely related with birth weight after adjusting for confounding variables (${\beta}=-0.077$, p=0.037). After stratifying hair nicotine levels by tertiles (T1, low [0.0-0.28 ng/mg]; T2, medium [0.29-0.62 ng/mg]; and T3, high [0.63-5.99 ng/mg]), the mean birth weight in each groups were 3,342g (T1) 3,296g (T2) and 3,290 g (T3), respectively. However the difference between groups was not statistically significant by analysis of co-variance (ANCOVA) adjusting for covariates (p=0.062). In logistic regression analysis, the risk of SGA was higher in the T3 (OR=1.59, 95%CI 1.05-2.42) than in the reference group (T1), after controlling for confounding variables. The risk of low birth weight (<2,500g, LBW) was not significantly higher (OR=1.44, 95%CI 0.95-2.19), but the risk of babies being below 3,000g birth weight was increased in the T3 group (OR=1.53, 95%CI 1.00-2.36) compared with that in the T1 group. Conclusions: Maternal ETS exposure during pregnancy was inversely related with birth weight. The risk of SGA increased in the highest ETS exposure group compared with in the low exposure group. To prevent ETS exposure during pregnancy, more comprehensive tobacco control policies are needed.

As developing satellite communication, the tracking range of the moving objects which move in local area is expanded to the whole world. However previous logistics management system is able to monitor freight which transporting in local area using mobile communication system. In this paper, we propose the reefer container management system that manages the location information and other related information such as temperature, humidity of container using the satellite system. The proposed system consists of three parts; data collector, satellite communication manager, reefer container information manager. And the proposed system uses the moving object index for managing the trajectory of container and tracing the location of container or vessel that is transporting the container, and supports various services such as reefer container and vessel tracking, container control and container statistics to logistic companies like shipper and forwarding agent. And the system can be increasing the quality of container transportation service to the shipper, and it makes the efficient management of reefer container to the shipping company.
