Background: Neurolytic celiac plexus block (NCPB) is a typical treatment for severe epigastric cancer pain, but the therapeutic effect is often affected by the variation of local anatomical structures induced by the tumor. Greater and lesser splanchnic nerve neurolysis (SNN) had similar effects to the NCPB, and was recently performed with a paravertebral approach under the image guidance, or with the transdiscal approach under the guidance of computed tomography. This study observed the feasibility and safety of SNN via a transdiscal approach under fluoroscopic guidance. Methods: The follow-up records of 34 patients with epigastric cancer pain who underwent the splanchnic nerve block via the T11-12 transdiscal approach under fluoroscopic guidance were investigated retrospectively. The numerical rating scale (NRS), the patient satisfaction scale (PSS) and quality of life (QOL) of the patient, the dose of morphine consumed, and the occurrence and severity of adverse events were recorded preoperatively and 1 day, 1 week, 1 month, and 2 months after surgery. Results: Compared with the preoperative scores, the NRS scores and daily morphine consumption decreased and the QOL and PSS scores increased at each postoperative time point (P < 0.001). No patients experienced serious complications. Conclusions: SNN via the transdiscal approach under flouroscopic guidance was an effective, safe, and easy operation for epigastric cancer pain, with fewer complications.

For the past few years, the video surveillance market has shown a rapid growth due to the increasing demand for Closed Circuit Television(CCTV) by the public sector and the private security industry. While the overall utilization of CCTV in the public and private sectors is expanding, its usage in the field of disaster management is less than sufficient. Therefore, the authors of this study, in an effort to revisit the role of CCTV in disaster situations, have carried out a case analysis in the vicinity of the Gangnam Station which has been designated as a natural disaster-prone area. First, the CCTV images around the target location are collected and the time and depth of inundation are measured through field surveys and image analyses. Next, a rainfall analysis was conducted using the Automatic Weather Station(AWS) data and the past inundation records. Lastly, the authors provide an estimate of rainfall for the areas around the station and suggest viable warning systems and countermeasures. The results from this study are expected to make positive contributions towards a significant reduction of the damages caused by the floods around the Gangnam Station.

Beam hardening artifact happens in the CT image. when a PET/CT is conducted while there is a metallic dental implant. The artifact appears in the CT image can affect the PET image. When the patient with head and neck cancer has a metallic dental implant, Beam hardening artifact which was taken in th CT image can change the PET image and SUV value. Therefore, by Quantitative measure of the SUV according to the change in HU by the metallic dental implant, the appropriacy in the clinical application was assessed. The records of 47 patients with PET/CT August 2011. For the analysis, 2 region of interest were defined in area where CT and PET image. As a result of the experiment, if there in an implant, the HU and the SUV increased and there existed a statistically significant difference(p<0.01). Although this level of increase was not large compared with that in the patient who have no metallic dental implant, when a person has head and neck cancer, it is even more likely to be overestimated when diagnosing the cancer. When conducting PET/CT for the patient who have head and neck cancer, the physical biological parts should be considered in order not to make an error in decoding.

Purpose: Traumatic cervical SCI is frequently accompanied by dural tear and the resulting cerebrospinal fluid (CSF) leak after surgery can be troublesome and delay rehabilitation with increasing morbidity. This study evaluated the incidence of intraoperative CSF leaks in patients with traumatic cervical spinal cord injury (SCI) who underwent anterior cervical surgery and described the reliable management of CSF leaks during the perioperative period. Methods: A retrospective study of medical records and radiological images was done on patients with CSF leaks after cervical spine trauma. Results: Seven patients(13.2%) were identified with CSF leaks during the intraoperative period. All patients were severely injured and showed structural abnormalities on the initial magnetic resonance image (MRI) of the cervical spine. Intraoperatively, no primary repair of dural tear was attempted because of a wide, rough defect size. Therefore, fibrin glue was applied to the operated site in all cases. Although a wound drainage was inserted, it was stopped within the first 24 hours after the operation. No lumbar drainage was performed. Postoperatively, the patients should kept their heads in an elevated position and early ambulation and rehabilitation were encouraged. None of the patients developed complications related to CSF leaks during admission. Conclusion: The incidence of CSF leaks after surgery for cervical spinal trauma is relatively higher than that of cervical spinal stenosis. Therefore, one should expect the possibility of a dural tear and have a simple and effective management protocol for CSF leaks in trauma cases established.

Purpose: The purpose of this study was to demonstrate effects of a critical pathway (CP) for stroke patients seen in emergency rooms (ER). Method: The CP developed by the CP committee consisted of 8 criteria: behavior of doctors and nurses, laboratory tests, Image testing, medication, treatment, activity, and nutrition. According to application of CP, a control group (n=17) and experimental group (n=17) were defined. Time was checked by the electronic medical records. Result: Use of CP for stroke patients in the ER, resulted in a decreased length of stay in ER (t=2.341, p=.026), and time required for image testing (t=2.623, p=.021), and an increased number of patients using rtPA ($x^2$=4.802, p=.049). Time required for neurology doctor contact, for neurology doctor to see patient in the ER, and for report of blood tests decreased, but there were no statistical significance. Conclusion: Quick responses are most important in the ER, so CP for these patients is a very effective patient management tool. To reduce delay in stroke diagnosis, continuous education programs for similar symptoms are necessary. CPs for other patients in the ER should be developed, and studies on cost and satisfaction, as well as length of stay, should be done.

The recent development of embodiment technology of the medical images makes most medical institutions introduce PACS(Picture Archiving and Communication System) in haste. However lots of PACS solutions, currently developed and distributed, haven't been able to serve the convenience of users and to satisfy user's demand because of economic limitations and administrator-oriented considerations in the process of development. So we have developed MIH(Medical Image History), by which we can search and refer to the patient's medical images and information with few restrictions of time and space for diagnosis and treatment. This program will contribute to the improvement in the medical environment and meet the clients' need. We'll make more effort to develop the application which insures the better quality of medical images. MIH manages the patient's image files and medical records like film chart in connection with time. This trial will contribute to the reduction of the economical loss caused by unnecessary references and improve the quality in the medical services. The demand on the development or the program which refers to the medical +ata quickly and keeps them stable will be continued by the medical institute. This will satisfy the client's demand and improve the service to the patients in that tile program will be modified from the standpoint of the users. MIH is trying to keep user-oriented policy and to apply the benefit of the analog system to the digital environment. It is necessary to lead the public to the better understanding that the systematic management and referring of the medical images is as important as the quality of the images.

The praying sentences of the script of Saddharmapundarika-sutra NO.5 which was made by prayer Bang-Ui, prince Ik-An, was investigated and the cover painting, Byonsangwha(Buddha's preaching painting), and letter style written in the script were discussed in this study. The cover painting on the script is known to be followed to the style of the cover painting as shown in a set of 7 rolls of Saddharma pundarika-sutra of the Horim Museum collection. It is not so difficult to say that the characteristics of cover painting of the script would be suceeded to those of scripts of the end of Koryo and the early Choseon Dynasty. Lotus and its surround was decorated with arabesque figure whose stems were drawn with golden paste and the arabesque figures were done with silver paste. However, for the expression of lotus and arabesque pattern the special feature of drawing style that was originated from the end of Koryo Dynasty to draw the outline with broad line and/or the hardness of drawing line became much more deepened than ever. It is not different to think that this characteristics should be those of Choseon Dynasty. On the Byeonsangwha(buddha's preaching painting) the painting of scattered flowers on stairs of Sumera-Mandala and the scheduled clouds (underseen from heaven) were as similar as to the Byeonsangwha style of the end of Koryo and the early Choseon Dynasty. However, the image of Shakyamuni and/or the halo(光背) is nearly same as the characteristics shown on the Beonsangwha of Saddharma pundarika-sutra of Nesosa' collection, a set of seven rolls which was completed in the 15th year of king Taejong(AD 1415). It is apparent that these characteristics are those of Choseon Dynasty. After king Chungsean in Koryo Dynasty, letter style of Chao Meng-Fu was shown in the script of late Koryo Dynasty as a new letter style.

The principal objective of this study was to analyze and conceptualize the socio-psychological burden in utilizing a nursing home for elderly. The subjects were five elderly from a private nursing home located in Seoul and their familial caregivers. An old male and three females were currently staying at the facility, and a female had been discharged already from there. Data were collected through depth interviews, observations and review of records at the facility For analysis, the data were classified by similar contents among significant expressions and factors in common. The subjects' motives to consider admission to the nursing home might be attributed to familial caregivers' burden, a shortage of support, environmental improvement and feeling of helplessness for the case elderly. The concept of burden is including family members' being badly off in living, their weariness, complications among family members, feeling psychological uneasiness, and hospital expenses. The identified image of nursing homes for the elderly in Korea was generally negative at the point of high cost, unreasonable requisites and limitations for admission to the facilities, inferior situations, and especially in that there were few long-term care facilities within the community boundary. From their experience of nursing homes, the interviewees have felt the sentiments of sorry for their old parents, with the thought of being an undutiful, bitterness, and empathy. Additionally, they expressed a sense of anxiety of relative deprivation against the fact that there were no long-term care facilities available for the middle class. On the basis of these, multi-dimensional needs could be identified for the elderly with chronic illnesses.

Background :The authors have developed a Digital image chart(DIC) and digital Radiotherapy Record System (DRRS). We have evaluated the DIC and DRRS for reliability, usefulness, ease of use, and efficiency. Materials and Methods :The basic design of the DIC and DRRS was to build an digital image database of radiation therapy Patient records for a more efficient and timely flow of critical image information throughout the department. This system is a submit of comprehensive radiation oncology management system (C-ROMS) and composed of a picture archiving and communication system (PACS), a radiotherapy information database, and a radiotherapy imaging database. The DIC and DRRS were programmed using Delphi under a Windows 95 environment and is capable of displaying the digital images of patients identification photos, simulation films, radiotherapy setup, diagnostic radiology images, gross lesion Photos, and radiotherapy Planning isodose charts with beam arrangements. Twenty-three clients in the department are connected by Ethernet (10 Mbps) to the central image server (Sun Ultra-sparc 1 workstation). Results :From the introduction of this system in February 1998 through December 1999, we have accumulated a total of 15,732 individual images for 2,556 patients. We can organize radiation therapy in a 'paperless' environment in 120 patients with breast cancer. Using this system, we have succeeded in the prompt, accurate, and simultaneous access to patient care information from multiple locations throughout the department. This coordination has resulted in improved operational efficiency within the department. Conclusion :The authors believe that the DIC and DRRS has contributed to the improvement of radiation oncology department efficacy as well as to time and resource savings by providing necessary visual information throughout the department conveniently and simultaneously. As a result, we can also achieve the 'paperless' and 'filmless' practice of radiation oncology with this system.

Purpose : Reversible posterior leukoencephalopathy syndrome is a complex disorder with characteristic clinical and radiologic findings that mainly involve the white/gray matter of the parieto-occipital lobes. The purpose of this study was to determine its clinical and radiological characteristics. Methods : A total of 15 pateints were involved in the study. Their medical records and radiological features of brain MRI were retrospectively reviewed and analyzed. Results : Fifteen pateints were involved. (9 males and 5 females). The patients' ages ranged from 2-20 years (mean age : 10 years). The brain MRI revealed fairly symmetric areas of increased T2 signal involving both white and gray matter of parieto-occipital regions. The condition seemed to be associated with cyclosporin A and steroid therapy or a variety of other conditions in which blood pressure rises acutely. Conclusion : Reversible posterior leukoencephalopathy syndrome is a complicated neurological condition, but a better understanding of this complex syndrome may obviate unnecessary investigations and lead to prompt and appropriate management of the associated problems.
