  • Subarachnoid pleural fistula (SPF) is an aberrant communication between the pleural cavity and subarachnoid space, resulting in uncontrolled cerebrospinal fluid drainage. The negative pressure of the pleural cavity creates a continuous suctioning effect, thereby impeding the spontaneous closure of these fistulas. Dural tears or punctures in cardiothoracic procedures, spinal operations, and trauma are known to cause such abnormal communications. Failure to recognize this entity may result in sudden neurological or respiratory complications. Hence, a high index of suspicion is required for early diagnosis and prompt management. Noninvasive positive pressure ventilation has been described to be effective in managing such fistulas, thus mitigating the high morbidity associated with exploratory surgery for primary repair. Herein, we describe the typical presentation of SPF and the clinical course, treatment, and follow-up of a patient who sustained SPF following anterior thoracic spinal surgery.

  • 2020년까지 전 세계 수송에너지의 수요가 현재의 2배까지 증가할 것으로 예상되면서 석유 자원의 안정적 공급이 어려워지기 이전에 이를 대체할 수 있는 에너지원 개발이 시급하다. 이러한 노력의 일환으로 최근 들어 대두되고 있는 가스화용융 기술은 석탄 폐기물 등으로부터 합성가스를 생산하는 고청정 고효율 기술이다. 여기에서 생산되는 합성가스는 천연가스를 대체하여 전기 및 화학원료를 생산하기 위한 원료로 이용 가능하다. 폐기물로부터 가스화용융기술을 통하여 생산되는 합성가스로부터 DME(dimethyl ether)를 생산할 수 있다. 가스화용융기술로부터 생산되는 합성가스는 자체의 일산화탄소와 수소의 조성비가 DME를 합성하는데 적당하다고 알려져 있다. DME는 에너지원의 다원화와 대기오염 물질의 저감, 지구온난화 대응 등과 아울러 제 4세대 수송 연료로 부각되고 있다. DME를 합성하는 방법은 합성가스로부터 메탄올의 합성 단계를 거친 후 DME를 합성하는 간접법과 단일단계의 반응에서 합성가스로부터 직접적으로 DME를 합성하는 직접법이 있다. 현재는 화학 평형적 측면 경제적 측면에서 이점을 가지고 있는 직접법에 관한 연구가 활발히 이루어지고 있다. DME 직접합성법에서는 메탄올 합성 촉매와 메탄올 탈수촉매의 물리적 혼합에 의한 혼성촉매가 주로 이용되고 있는 것으로 알려져 있다 본 연구에서는 일산화탄소와 수소로 이루어진 합성 가스로부터 직접 DME를 생산할 수 있는 직접 합성 공정에 적용 가능한 고효율 촉매 기술을 개발하기 위해 상용촉매의 스크린 테스트를 수행하였다. 상용촉매로는 sud-chemi사에서 메탄을 합성 촉매와 탈수촉매를 각각 구입하였으며, 이들 촉매를 원하는 조성비로 물리적으로 혼합한 다음 반응온도 ($250-290^{\circ}C$) 압력 (30-50 atm), $H_2$/CO 몰비 (0.5-2.0) 등의 다양한 반응조건 하에서 스크린 테스트를 수행하였다.대장조영영상을 얻을 수 있어 대장암의 위치에 관한 정보를 삼차원적으로 제공하므로 대장암의 성상을 정확히 알 수 있는데 도움을 주었다.요인은 없는 것으로 사료된다. 이 중 2예의 CT에서 선상 혹은망상형의 음영을 보였다. 결론: 유방암 환자의 방사선 치료 후 CT 소견은 방사선 치료의 방법에 따라 폐첨부 혹은 폐의전면 흉막하 부위에 선상 혹은 망상형의 음영으로서 방사선 폐렴 혹은 섬유화 소견이다.

  • A small cationic peptide (JH8944) was tested for activity against a number of pathogens of agricultural crops. JH8944 inhibited conidium growth in most of the tested plant pathogens with a dose of $50{\mu}g/ml$, although one isolate of Fusarium oxysporum was inhibited at $5{\mu}g/ml$ of JH8944. Most conidia of Fusarium graminearum were killed within 6 hours of treatment with $50{\mu}g/ml$ of JH8944. Germinating F. graminearum conidia required $238{\mu}g/ml$ of JH8944 for 90% growth inhibition. The peptide did not cause any damage to tissues surrounding maize leaf punctures when tested at a higher concentration of $250{\mu}g/ml$ even after 3 days. Liposomes consisting of phosphatidylglycerol were susceptible to leakage after treatment with 25 and $50{\mu}g/ml$ of JH8944. These experiments suggest this peptide destroys fungal membrane integrity and could be utilized for control of crop fungal pathogens.

  • The objectives of this study were to investigate the status of accidents and to assess hazards in institutional foodservices in the Changwon and Masan areas. A survey was conducted from February 1 to March 31, 2009 using questionnaires, and 142 dietitians participated. The dietitians' perception of accident risks in workplace averaged 3.11 points. Forty-five percent of the respondents responded that accidents had occurred more than once between 2006 and 2008. In addition, 28.2% of the respondents experienced employee absences or turnover due to accidents during Year 2008. 'Musculoskelectal injuries or disorders (65.5%)', 'slips or falls (64.8%)', 'burns (57.7%)', and 'cuts and punctures (48.6%)' were the predominant accidents in foodservice. 'Knives (76 points)', 'steam kettles (41 points)', 'vegetable cutters (34 points)' and 'turn kettles (26 points)' were the equipment with severe accidents, such as burns or cut injuries. Among foodservice processes, 'carpal tunnel syndrome while washing (2.83 points)', 'burned by frying oil (2.64 points)', 'cut by sharp tools (2.55 points)', 'musculoskelectal injury by moving heavy weight food materials (2.41 points)', and 'injury by slipping on wet workplace floors and trenches (2.19 points)' were the most frequently occurring accidents at foodservice sites. To prevent safety accidents, dietitians' perceptions of safety supervision should be improved, and therefore, it is necessary they receive safety education.

  • Various types of geosynthetics have been manufactured and their applications are rapidly extended disregarding unreliable lifetime, chemical and biological persistence and puncture resistance. Puncture resistance of geosynthetics in earth structures and liner systems has been a critical issue to be improved. In this paper, comparative studies were made on a puncture resistance of various geosynthetics that were used to a liner system. Two types of puncture tools and rubles and gravels were used to generate punctures on geosynthetics. From the results it is shown that types of puncture tools affect puncture resistance of materials significantly and puncture forces were irregular depending upon puncture tools and materials.

  • Purpose: The purpose of the study is to investigate the relationship between total serum bilirubin(TSB) and transcutaneous bilirubinometry(TcB) in neonates with jaundice. Method: TcB from various sites(forehead, sternum, abdomen, buttock, hand, dorsalis-pedia) was measured using a JM-102 in a total of 102 neonate, 42 female and 60 male, with the mean 37.5 gestational week and the mean 2,903 gram of birth weight, as well as TSB from capillary punctures. Result: The mean bilirubin was 11.73 in serum, 20.55 on the forehead, 17.23 on the sternum, 16.19 on the abdomen, 18.22 on the buttock, 15.83 on the hand and 15.49 on the dorsalis-pedia. The relationship between TSB and TcBs were formulated by simple regression with 0.406 < r < 0.668(p < .000). A higher relationship was revealed between TSB and TCB at the forehead in infants of full-term, ABO incompatibility, and Hb greater than 16 mg/dl(r =0.725, 0.790, and 0.717, retrospectively). Phototherapy altered the measurement of TcB per site. Conclusion: TcB on the forehead is a reliable, noninvasive and convenient measurement of TSB in normal infants(Institutions need to establish quantitative equations representing the specific relationship between TSB and TCB according to the hemodynamic problems of infants such as ABO incompatibility, or low Hb).

  • Field studies on the damage type of rice plants by the rice stem maggot in the second generation were conducted at Yong-in, Gyonggi Province, in 1982. Rate of damaged ears and the number of punctured leaves were higher in Tongil line than Japonica line. Early heading cultivars usually had bottom-damaged ears and on the contrary late heading cultivars had upper?damaged ears. In Tongil line, many of the upper-damaged or middle-damaged ears had punctured-flag leaves and less first leaves with punctures, but most of the bottom-damaged ears had not punctured-leaves. When matured, the larvae moved up to the upper part of stem and pupated on the upper and inner part of leaf-sheath of flag or first leaves.

  • Purpose: The purpose of this was to compare effects of application of the skin stimulation method and topical anesthetic cream on pain, heart rate variability and satisfaction according to nursing intervention methods during arteriovenous fistula puncture in chronic renal failure hemodialysis patients. Methods: This study was a crossover design. Participants were 36 patients with chronic renal failure receiving hemodialysis treatment. Two forms of intervention were applied to participants, and then pain and heart rate variability were measured during the puncture. Results: There were no statistically significant differences according to each treatment in vein pain and artery pain. Also, there were no statistically significant differences according to each treatment in stress index, sympathetic activity (LF), parasympathetic activity (HF) and sympathetic activity/parasympathetic activity (LF/HF ratio). Satisfaction with application of skin stimulation method was statistically higher than that of topical anesthetic cream application. Conclusion: This suggests that application of the skin stimulation method complements disadvantages of topical anesthetic cream application and demonstrates possibility of application as a nursing intervention method which can be conveniently used by nurses in clinical practice.

  • Purpose: This study was conducted to examine the effects of ethyl chloride spray during arteriovenous fistula puncture on pain, depression, and noncompliance in hemodialysis patients. Methods: This study used a randomized controlled trial design on adults with chronic renal failure who received hemodialysis treatment through arteriovenous fistula. Ethyl chloride spray was applied to 20 subjects in the experimental group during arteriovenous fistula puncture, and a placebo spray was applied to 20 subjects in the control group; the intervention was conducted 12 times for 4 weeks. A total of 33 participants were used in the final analysis. The outcomes were measured using the face pain rating scale, Center for Epidemiological Studies Depression Scale (CES-D), and modified United States Renal Data System tools. Results: As a result of the pre-homogeneity test between the two groups, it was confirmed that the sexes were not homogeneous. Therefore, sex was treated as a covariate and analyzed. Puncture pain was significantly reduced in the experimental group (p<.001). However there was no significant difference between the groups in depression and noncompliance. Conclusion: Ethyl chloride spray was convenient and effective pain management intervention for both hemodialysis patients and medical staff.
