임베디드 시스템 교육을 위한 Windows CE 이식 절차
유호경,이명의 한국기술교육대학교 2003 論文集 Vol.10 No.1
This paper deals with a porting procedure for a real-time operating system. Windows CE is widely used in various post PC products due to having a strong multimedia capability in Web browser and Media player. Also, MediaGX processor is well known that it has compatibility with Intel x86 processor, and a lot of off-the-shelf source code program can be used. With merits stated above, Internet Appliance(IA) equipments such as PDA, Thin client, Set-Top-Box, and Web terminal have been choosing MediaGX processor as a CPU in the current market. The description of Win CE porting procedure is presented, and the experimental results are shown via a real implementation in this paper. This porting description proposed will be invaluable for the student in studying the subject related to embedded systems and real-time operating system.

Polycythemia vera is one of the myeloproliferative diseases, and as such, is an example of clonal hematopoiesis. The progeny of a single, abnormal, hematopoietic stem cell gain a grwoth advantage over their normal counterparts resulting in overproduction of red cells generally accompanied by overproduction of granulocytes and platelets as well. There are a variety of nonspecific symptoms at onset related to the increased red cell mass and hematocrit accompanied by the more specific manifestations of pruhtis, erythromelalgia, and hepatic, portal, and mesenteric vein thrombosis. Splenomegaly and hypertension are common. Thrombosis and leukemia are frequent complication in polycythemia vera and are associated with severa organ damage and a high mortality. We report here the case of occurrence of myocardial and cerebral infarction in a patient with polycythemia vera.

This research aims to develop a new evuluation method of endurance for elementary school students. The norm of the event of 1,000m running-walking was examined and reviewed. As a result, a new highly-valid norm for the present 1,000m running-walking was made. Among the 5th and 6th graders, 2,144 pupils were chosen. The subjects were given 1,000m running-walking and step test. The new norm led to the following results: 1. The frequency distribution of PEI according to Cajori's 5-stage evaluation method turned out to be normal for both 5th and 6th graders. In conclusion, this new norm of 1,000m running-walking is believed to provide more valid and credible scores for elementary school students. The 1,000m running-walking records and the PEI will be used as the basic data for foretelling one's endurance.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

To develop a poloxamer-based solid suppository with poloxamer mixtures, the melting points of various formulations composed of P 124 and P 188 were investigated. To investigate the effect of poloxamer to the dissolution and dissolution mechanism of diclofenac sodium from the suppository the dissolution of diclofenac sodium delivered by the poloxamer-based suppository was performed. Furthermore, to investigate the mucoadhesive property of the poloxamer-based solid suppository, the identification test in the rectum was carried out after its rectal administration in rats. The poloxamer mixtures composed of P 124 and P 188 were homogeneous. Very small amounts of P 188 affected the melting points of poloxamer mixtures. In particular, the poloxamer mixture [P 124/P 188 (97/3%)] with the melting point of about 32℃ was a solid form at room temperature and instantly melted at physiological temperature. Furthermore, very small amounts of P 188 in the poloxamer-based suppository hardly affected the dissolution rates of diclofenac sodium from the suppository. Dissolution mechanism analysis showed the dissolution of diclofenac sodium was proportional to the time. At 4 h after administration, the blue color of poloxamer-based suppository [diclofenac sodium/poloxamer mixture (2.5/97.5%)] with the P 124/P 188 ratio of (97/3%) and blue lake in the rectum was faded. However, the position of suppository in the rectum did not significantly change with time. Thus, it retained in the rectum for at least 4 h. Our results indicated that the poloxamer-based solid suppository with P 124 and P 188 would be a candidate of rectal dosage from for diclofenac sodium.

To develop a clotrimazole-loaded solid suppository with poloxamer and propylene glycol, the melting points of various formulations composed of poloxamer 188 (P 188) and propylene glycol were investigated. The dissolution study of clotrimazole delivered by the suppository composed of P 188 and propylene glycol was performed. The mixtures composed of P 188 and propylene glycol were homogeneous. Propylene glycol affected the melting points of poloxamer mixtures. In particular, the mixture [P 188/propylene glycol (70/30%)] with the melting point of about 32°C was a solid form at room temperature and instantly melted at physiological temperature. Furthermore, propylene glycol affected greatly the dissolution rates of clotrimazole from the suppository. Dissolution mechanism analysis showed the dissolution of clotrimazole was proportional to the time. Our results indicated that the solid suppository with P 188 and propylene glycol would be a candidate of rectal dosage form for clotrimazole.

Paraquat is a bipyridilium nonselective contact herbicide and well-known pulmonary toxicants. Concentrated solution of paraquat may causes severe corrosive injury and multiple system organ failure. It is poorly absorbed from GI tract, but is extremely toxic and so one swallowed mouthful of Gramoxone(about 5ml) will be fatal. We experienced 3 cases of paraquat poisoning through injection and examined pathologic findings, medical records and concentration of paraquat in blood and tissues. We reviewed the mechanism of action of paraquat. pathologic changes of organ system, concentration of compound in the various organ and cause of death in autopsy cases.
Case Report : Relief of Postherpetic Neuralgia with Transforaminal Epidural Injection of Magnesium
( Ho Kyoung Yu ),( Joon Ho Lee ),( Sung Hwan Cho ),( Yong Ik Kim ) 대한통증학회 2011 The Korean Journal of Pain Vol.24 No.1
Although postherpetic neuralgia (PHN) is a common chronic pain syndrome, the pathophysiology of this disorder is not well known and management is often very difficult. N-methyl-D-Aspartate (NMDA) receptor antagonists are known to be effective in PHN, and magnesium, a physiological blocker of NMDA receptors, is widely used to treat various chronic pain disorders. Here, we present a case of the PHN refractory to conventional treatment, which was treated successfully with transforaminal epidural injection of magnesium sulphate at the affected dermatome.
