Rheumatoid arthritis frequently involves the cervical spine and may lead to neurologic impairement. However, direct involvement of CNS structures by inflammatory cells has been reported infrequently. The prevalence of this complication of rheumatoid arthritis is unknown. Inflammatory CNS involvement in rheumatoid arthritis reportedly occurs in the setting of longstanding, active, erosive articular disease and is accompanied by extracranial and extraspinal nodules and vasculitis. This is diagnosed by radiologic finding of CNS nodules or meningeal thickening and by biopsy or autopsy. Treatment with corticosteroid, cytotoxic agent or surgical decompression is helpful. But the majority of patients die within several months of onset of neurologic symptom. Recently, we experienced a case of pachymeningitis caused by rheumatoid arthritis, which resolved repeatedly with azathioprine treatment.

문명의 발달, 인구의 증가 및 스포츠의 대중화로 인하여 교통사고, 산업재해, 상해, 및 스포츠로 인한 외상이 증가하고 있으며 손상의 양상도 보다 다발성이며 심각한 양상을 보이는 경우가 많아지게 되었다. 악안면부위에 외상을 가지는 경우, 신경외과나 정형외과적 영역의 손상을 동반하는 경우가 흔하며 이들 타과와의 협조하에 환자치료에 임하게 되는 경우가 많아지고 있다. 본 연구는 1991년 3월부터 1994년 2월까지 동국대학 부속병원 구강악안면외과에서 치료받은 214명의 안면골 골절 환자중 타과에서 대진의뢰를 받아 치료를 시행한 49명을 대상으로 방사선 사진과 의무기록 확인을 통하여 다음과 같은 결론을 얻었다. 1. 전체 안면골 골절환자중 타과에서 대진의뢰된 환자는 23%였으며, 남자 대 여자의 비율은 4.4:1로 남자에서 호발하였다. 2. 연령별로 보면, 20대(37%)와 30대(29%)에서 호발하였다. 3. 관골부(53%), 하악골(47%), 상악골(22%), 안와골(14%), 비골(8%)의 순으로 골절이 발생하였다. 4. 교통사고(76%)가 압도적인 손상의 주요원인이었다. 5. 신경외과(78%)에서 가장 많은 환자를 안면골 골절로 대진의뢰하였다. 6. 대진의뢰하는데 소요되는 기간은 1일이 69%, 2∼3일이 25%로 3일 이내에 대부분 처리되었다. 7. 비관혈적 정복술만으로 치료한 경우(4%)보다 비관혈적 정복술이 동반되거나 혹은 관혈적 정복술 만을 시행한 경우(86%)가 많았으며, 관혈적정복술은 소형금속판이나 강선을 이용하였다. 8. 1주일 이내에 80%의 환자가 골절에 대한 처치를 시행받았다. 9. 감염, 부정교합, 개구장애, 악관절 동통 등의 합병증이 24%로 일반적 안면골 골절환자에 비하여 비교적 높은 비율로 발생하였다. 안면골 골절시 치유경과 및 회복은 골절이 정도 및 양상, 환자의 연령, 타부위 연관손상 등에 의하여 많은 영향을 받게 되므로, 고도의 의료기술을 활용한 타과와의 신속하고 긴밀한 유기적 협조체체와 술후의 지속적, 주기적인 임상검사 및 연구가 요할 것으로 사료된다. This is a retrospective study on 49 facial bone fracture patients consulted to Department of Oral and Maxillofacial Surgery from March 1991 to February 1994. The obtained results were as follows. 1. Of the 214 patients with facial bone fractures, 49 patients(23%) were consulted and male to female ratio was 4.4:1. 2. The age frequency was the highest in the 3rd decade(37%)and then 4th decade(29%). 3. The zygomatic area(53%) was the most frequent site and then mandible(47%), maxilla(22%), orbit(14%) and nasal bone(8%). 4. Traffic accident was the most frequent cause(76%). 5. Seventy eight percent of the patients were consulted from neurosurgery. 6. The durations form trauma to consult were largely within 3 days(94%). 7. The open reductions(86%) were more frequent than the closed reductions(4%) when surgical treatments were performed. 8. The duration from trauma to operation were within 1 week, in 80%. 9. The complications in consulted patients were more frequent(24%) than other general facial bone fractures.

The effect of ultrasonic melt treatment (UST) on the solidification microstructure of an Al–5Ti–1B alloy containing highvolumefractions of Al3Tiand TiB2particles is investigated for various UST times with different melt holding times. Theas-cast Al–5Ti–1B alloy is composed of TiB2and polygonal Al3Tiparticles (present prior to UST), plate-like Al3Tiparticles,and Al grains (formed during UST and/or solidification). The UST causes a size reduction and homogeneous distributionof the TiB2-agglomerated region containing many submicron-sized TiB2particles pushed to the grain boundaries. The USTslightly decreases the size and improves the distribution of polygonal Al3Tiparticles enriched in the TiB2-agglomeratedregion. Unlike the TiB2and polygonal Al3Tiparticles, which exhibit a minor refining effect, the plate-like Al3Tiparticlesshow a significant refinement with UST application. The UST has a significant effect on the size distribution of Al grains byinducing the formation of medium-sized grains at the expense of small and large grains; however, it only has a slight effecton grain refinement. The degree of microstructure modification increases with increasing UST time but decreases with meltholding time after UST. The mechanisms for the refinement and dispersion of the TiB2and Al3Tiparticles and Al grains arediscussed considering fragmentation, nucleation, and growth behaviors induced by the UST and subsequent solidification.

Acinar cell carcinoma is a rare tumor that represents 1~2% of al1 pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-o1d man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased ^(18)F-fluorodeoxyglucose (FDG) uptake Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the Pancreas The patient underwent a total gastrectomy three months later because of gastric recurrence Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabme.

Syncope is not uncommon problem that needs broad differential diagnosis. Correct diagnosis of the cause of syncope is important, because although some causes of syncope such as vasodepressor syncope have benign prognosis, others such as ventricular tachycardia may need prompt diagnosis and treatment. We present a retrospective study of the patients with episodes of syncope brought to Emergency Medical Center of Chung Ang Gil Hospital from January 1994 to October 1994 and the results were as followings. 1. The patients with episodes of syncope accounte for 0.5% of total Emergency Department visits. 2. The male to female ratio was 4 : 6 and mean age was about 54-years old. 3. The cause of syncope was identifiable in 48% of the case and not in 52%. The noncardiac cause(56%) was more common than the cardiac(44%) and cardiac, noncardiac, SUO(Syncope of Unknown Origin) ratio was 1 : 1.4 : 2.6. 4. 29% of patients were dignosed by history taking, physical examination, and electrocardiography when they visited the Emergency Department initially, and 88% of patients with identifiable causes were diagnosed through initial Emergency Department investigation and Holter monitioring. 5. The rate of correct diagnosis can be increased if initial investigation includes Holter monitoring, and the further research for more accurate, inexpensive and noninvasive diagnostic method for syncope is needed.

Maize hybrids were planted on April 1, April 25, May 20 and June 15 in 2012, 2013 at the experimental paddy and upland fields in Suwon city , respectively to know changes of growth stage and yield according to different planting time. Maize planting on April 1 was not recommended because total growing days at planting on April 1 was not different with that at planting on April 25 due to many days from planting to emergence over 20 days at planting on April 1. Total growing days were not much different among three planting time after April 25 because days from silking to maturity was lengthened though days from planting to silking was shortened at later planting time. Stalk weight was decreased as planting time was delayed, particularly at planting times after May 20 at paddy field by excess water injury during early growth stage. But, grain yield was not low as in May and June. It is needed to introduce early maturity maize variety as Yanganok at late planting for higher grain yield and enough time for soil preparation for next winter crops

Background : The cun measurement System, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and Small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height.

Youn Sun Son, Bong Yeon Hwang, Dae Taek Lee and Yoon Jung Bae. Effects of active drinking practices on fluid consumptionand sweat rate while exercising in a hot environment. JENB., Vol. 18, No. 2, pp.215-223, 2014 [Purpose]To examine the effectsof active drinking practices on fluid consumption and sweat rate while exercising in a hot environment. [Methods]Nine mencompleted two experiments. Each consisted of 3 phases: pre-testing (pre), training period, and post-testing (post). During testing,the subjects ran on a treadmill at a moderate intensity for 90 min at 39 ± 1℃ followed by a 3-h recovery. They drank ad libitum. During training, they ran for 90 min for 7 days while either drinking actively (AH, 150% of weight loss) or passively (PH,50% of weight loss). [Results]The actual volume consumed in training was three times greater during AH than during PH. Inpost during AH, the volume of drinking was two times greater than pre (1592 ± 953 and 855 ± 551 mL, respectively; p < 0.05). No difference in volume consumption during PH between pre and post was found. The sweat loss during exercise was greaterin post (1377 ± 956 mL) than in pre (558 ± 642 mL) during AH (p < 0.05), but not during PH. Rectal temperature and heartrate decreased after training. Serum osmolality following exercise were not different than the baseline or between the conditions. [Conclusion]Active drinking practices while exercising in a hot environment induced greater voluntary fluid intake and sweatloss. [Keyword]voluntary intake, rehydration, thermoregulation.
