We live in an age of information and an era of rising environmental awareness. As a result, efficient and judicious use of environmental information has become a prerequisite to planning and management of environmental affairs in contemporary societies. So, we have embarked on a study of Environmental Information System(EIS). In the first article, we discussed the status analysis of EIS in Korea, USA, and Japan. This study as the second project has three major components. First, it classifies items and sources of 22 EIA factors. Second, it explains building of environmental information comprising geographic and attribute data of 17 factors. Finally, the study presents applications of EIS as an alternative assessment of suitability analysis. Based on these analysis, the study makes some recommendations and conclusions.

As wireless and mobile technologies have advanced significantly, lots of large sized healthcare organizations have implemented so called mobile hospital (m-Hospital) which provides a location independent and point of care (POC) clinical environment. Implementation of m-Hospital enhances quality of care because health professionals such as physicians and nurses can use hospital information systems at the very place where patients are located without any delay. This paper presents a real-time patient monitoring system based on wireless network technologies. A general framework for the patient monitoring process is introduced and the architecture and components of the proposed monitoring system is described. The system collects and analyzes biometric signals of in-patients who suffer from cancer. Specifically, it continuously monitors oxygen saturation of patients in bed and alarms health professionals instantly when an abnormal status of the patient is detected. The monitoring system has been used and clinically verified in a university hospital.

Under the Enforcement Rules of the National Health Promotion Act, smoking areas in coffee shops in Korea should be divided off from other areas. The effect on indoor air quality of different division types for smoking areas was evaluated. Using real-time monitors, fine particulate matter <2.5 ${\mu}m$ in diameter ($PM_{2.5}$) concentrations were measured simultaneously in the smoking and non-smoking areas of 30 coffee shops in Seoul. Average $PM_{2.5}$ concentrations in smoking and non-smoking areas were 132 ${\mu}g/m^3$ and 52 ${\mu}g/m^3$, respectively; significantly different. Average $PM_{2.5}$ concentrations in non-smoking areas were 39 ${\mu}g/m^3$ in the glass-wall type and 64 ${\mu}g/m^3$ in the separate-floor type. These $PM_{2.5}$ levels were above the US national ambient air quality standard of 35 ${\mu}g/m^3$. Although indoor $PM_{2.5}$ levels in non-smoking areas were reduced by the division, the rates of reduction were not significantly different by division type. Our results demonstrated that $PM_{2.5}$ from smoking areas can infiltrate into non-smoking areas. Therefore, a complete indoor smoking ban in coffee shops is the only way to protect customers and workers in non-smoking areas.

Purpose The nuclear medicine examination, there is a difficulty to carry out the inspection of both on the day of residual isotope due to the half-life. In this study, by studying the mutual influence and $^{18}F$-FDG of $^{99m}TcO_4{^-}$, I would like to explain the matters to be considered in the case of performing the same day. Materials and Methods With the NEMA-1994 Phantom, and experiments were performed 3 times. Create a 1: 4 Background ratio HOT and the $^{99m}TcO_4{^-}$ The first experiment: After underwent SPECT in INFINIA (GE Healthcare, MI, USA), and were injected with $^{18}F$-FDG 37 MBq in the Background area, 13 once for 60 minutes under the same conditions was time Scan. Create a 1: 4 Background ratio HOT and the $^{18}F$-FDG second is: The Scan in PET/CT Discovery 600 (GE Healthcare, MI, USA), and 148 MBq after injection $^{99m}TcO_4{^-}$ the Background area, once for 60 minutes, 6 under the same conditions was time Scan. Create a 1: 4 Background ratio HOT and the $^{18}F$-FDG experiments las, increments of 296 MBq and 148 MBq the 1 Bed Scan after $^{99m}TcO_4{^-}$, was 1 Bed Scan under the same conditions. Non BKG area and HOT, I was measured comparing the Total Counts and SNR or CNR. Results Showed a significant difference in the ratio CNR of enforcement during SPECT $^{18}F$-FDG is, (p>0.05). The $^{99m}TcO_4{^-}$ was no significant difference between the SNR ratio of PET / CT at the time of the effective date (p<0.05). I got the results $^{99m}TcO_4{^-}$ that reduce the Total Counts of PET / CT scan. Conclusion If you make a PET / CT scan, may affect the test using the $^{99m}TcO_4{^-}$ up to 12 hours, when it is performed before the $^{99m}TcO_4{^-}$, does not affect the SNR and SUV, PET / CT scan I reduced the detection efficiency. The inspection of day, we'd like to recommend a way to complement the detection efficiency to increase the inspection time of PET / CT in move forward the inspection using the $^{99m}TcO_4{^-}$.

Purpose: Currently, PET/CT scan has been known to provide useful information to both preoperative and postoperative examination of cancer patients. Contracted stomach by the long fasting could cause difficulties of interpretation because of its size on reconstructed image data. To solve this problem, after the whole body PET/CT scan, patients were administrated in drinking 300 mL of water to expand stomach and performed additional scan on stomach region. Not only PET/CT scan but also CT performs this water-administration, and patients were take oral solution to make stomach expand for stomach cancer. When this scan performed, patients lay supine position. In this study, we evaluated the capacity of stomach through PET/CT scan with drinking water performed in supine and prone position so that we can distinguish exact location of cancer around pylorus and inferior wall of stomach. Furthermore, image data from supine and prone positions were analyzed the difference of volume of stomach through the change of standardized uptake values. Materials and Methods: From July 2009 to January 2010 in severance hospital, 30 patients who were diagnosed as early gastric cancer or advanced gastric cancer were chosen. All patients had PET/CT scan before the operation and have had follow-up PET/CT. The patients fast for at least 8 hours, and had an injection intravenously with $^{18}F$-FDG, 7.4 MBq (0.2 mCi/kg) per kilogram. They were rested for 60 minutes. Before the examination, all patients were administrated to drink water for 300 mL Patients had PET/CT scan with supine position around the region of stomach, whole body, and around the region of stomach with prone position after drinking another 300 mL of water respectively. Results: As a results of comparison between stomach capacity of 30 patients in supine and prone position, the study draw results that average capacity of stomach body was 460.29 $mm^2$ in supine position, and 641.39 $mm^2$ in prone position for 30 patients. The change of capacity shows 41.3% expanded in prone position. And there was no noticeable difference at maximum standardized uptake values in supine position and prone position. Conclusion: As results, stomach would have more expanded capacity in prone position than supine position. For patients who have physical disabilities to move freely, additional scan in prone position will be obstacle to perform. However, if additional scan in supine position add with the scan in prone position, it will be easier to diagnose stomach cancer. Moreover, we believe that this study will help the research for inventing support tools for patients who have physical disabilities in prone position.

Purpose: This study investigates morphologic change of the rectosigmoid colon using a belly board in prone position and distended bladder in patients with rectal cancer. We evaluate the possibility of excluding the proximal margin of anastomosis from the radiation field by straightening the rectosigmoid colon. Materials and Methods: Nineteen patients who received preoperative radiotherapy between 2006 and 2009 underwent simulation in a prone position (group A). These patients were compared to 19 patients treated using a belly board in prone position and a distended bladder protocol (group B). Rectosigmoid colon in the pelvic cavity was delineated on planning computed tomography (CT) images. A total dose of 45 Gy was planned for the whole pelvic field with superior margin of the sacral promontory. The volume and redundancy of rectosigmoid colon was assessed. Results: Patients in group B had straighter rectosigmoid colons than those in group A (no redundancy; group A vs. group B, 10% vs. 42%; p = 0.03). The volume of rectosigmoid colon in the radiation field was significantly larger in group A (56.7 vs. 49.1 mL; p = 0.009). In dose volume histogram analysis, the mean irradiated volume was lower in patients in group B (V45 27.2 vs. 18.2 mL; p = 0.004). In Pearson correlation coefficient analysis, the in-field volume of rectosigmoid colon was significantly correlated with the bladder volume (R = 0.86, p = 0.003). Conclusion: Use of a belly board and distended bladder protocol could contribute to exclusion of the proximal margin of anastomosis from the radiation field.

The purpose of this study is to evaluate the community based home care service, and make reorientation for better service. The data was collected from the public health center, which was operated for one year, 1997. This case is evaluated and reoriented according to five elements of public health care system; system of resources for public health, organization and administration, health care delivery system of financing, management. In resources for public health, available health personnels are 15 physicians, 17 nurses, 11 nurse aides and 2 other persons. One professional health personnel take care of 609 clients, The equipments used for elderly and the disabled are 6 wheelchairs, 4 walkers, 1 hairwashers and 30 viberations. But these equipments are not enough to deal all clients. In organization and administration, planning and setting goals for community home care are made by the director, supervisor of family department and public health nurse. So there is no regular commitee for home care services in this community. The form of delivery of health care is focused on preventive health care. The important works of public health nurse are health education, preventive care for hypertension, D.M. and vaccination of communicable desease. In finaning system, funds come from central government(8.3%), local goverment(16.7%) and health center itself(3.8%), The services consist of health education, vaccination, clinical test and equipment. There are several local volunteers, which are local hospitals, a college, a christian association, a catholic association, a drivers association and a disabled association. The volunteer groups give physical and mental support to the clients. In management, this health center has three evaluation methods. One is done by local government, one is done by health center itself, and the other is done by clients with questionair. But the evaluation tools are deferent between agency. Home care services must be planned and evaluated. This public health center has to have more personnel, equipments, education for professional kowledge and meetings with community volunteer agencies.

Purpose: This descriptive correlational study examined the acculturation, health literacy, and factors affecting the health literacy of Vietnamese and Chinese female marriage immigrants. Methods: The sample consisted of 90 Vietnamese and 89 Chinese female marriage immigrants who participated in Multicultural Family Support Centers' programs in metropolitan city A. The health literacy was measured by HLI-FMI (Health Literacy Index for Female Marriage Immigrants), acculturation was measured using the Acculturation Index for female marriage immigrants. Descriptive statistics, t-test, Chi-square, one-way ANOVA, Scheffé test, Pearson correlation coefficient, and multiple linear regression were performed for data analysis. Results: The Chinese group (M=9.80±2.72) showed a significantly higher health literacy than the Vietnamese group (M=8.07±3.57). The factors affecting health literacy among Chinese were the length of residence (β=.442 p<.001), and adaptation to Korean culture (β=.381, p=.007). Conclusion: To develope graded education programs for promoting the health literacy of Chinese and Vietnamese female marriage immigrants, the length of residence can be considered. Continuously providing a support system to help them adapt to Korean culture can also have a positive effect on health literacy.

Objectives: To assess the hazard of Korea chrysotile and anthophylite, fibers were analyzed for their physicochemical properties by transmission electron microscope equipped with energy dispersive X-ray spectrometer (TEM-EDS). Methods: To evaluate the biopersistence of 2 domestic asbestos, Sprague-Dawely rats were exposed to 2 mg asbestos by intratracheal instillation. Each asbestos (chrysotile ; $8,814,244{\times}10^6$ fibers/mg, average size $0.08{\mu}m{\times}4.39{\mu}m$, anthophyllite ; $5,182{\times}10^6$ fibers/mg, average size $0.95{\mu}m{\times}7.29{\mu}m$) were evaluated after a single intratracheal instillation. At times from 1 week to 4 weeks after exposure, the numbers of asbestos fivers in the bronchoalveolar lavage fluid and in the lung were calculated. Results: Anthophyllite fivers continuously have retained for 4 weeks but chrysotile fivers were rarely found at 4 weeks after exposure in the bronchoalveolar lavage fluid. Chrysotile fivers at 4 weeks after treatment were not observed but anthophyllite was easily observed in the lung with phase contrast microscopy. According to electron microscopic observation of asbestos in the lung, within 1 week after the administration of chrysotile fivers were decreased rapidly but anthophyllite fivers were very little change for 4 weeks. When chrysotile fivers have been lost Fe in 1 week, there were no significant changes in anthophyllite fivers in the lung. Conclusions: These findings indicate that after a long time exposure to chrysotile, asbestos bodies can not be found in the bronchoalveolar lavage fluid.
