서로 다른 입자크기의 3층구조를 갖는 튜브형태의 한외알루미나 분리막은, 일반적으로 제조공정중 분리층에 결손부분이 발생하기 때문에 낮은 선택도 및 제거율을 보인다. 이와같은 결손부분을 보정 하고 보정전, 후의 분리막에 대한 기체장치에 의한 투과도(permeability) 및 선택도(selectivity)를 측정하였다. Colloidal silica 솔의 deposition에 기인하여 기체 투과율의 감소가 60%였다. 한외알루미나 여과막의 보정에 있어서 습도조절에 의한 선택적 적심법은 비록 deposition에 의한 문제점을 내포하고 있으나, 기체분리에서도 효과적인 방법이다. The 3-layer tubular type alumina membrane consisting of different pore size shows the decreased selectivity and rejection because of cracks in the separation layer generally occurred during the manufacturing process. For the comparing of native and modified membranes, the modified membranes were tested by permeability by gas equipments, selectivity for the gases after caulking. The permeabilities are decreased 60% for the gas caused by deposition of colloidal silica sol after caulking. In conclusion, the Alternative Wetting Method by humidity control had the effect for the modification of ultrafiltration alumina membrane for separation of gases, though having problem of deposition.

The hospice activities in Korea have still stood in the premature stage, although the contemporary hospice program, which professionally accommodates terminally ill patients, appeared in the history 35 years ago. Especially, the availability of the facility hospice is not only poor in number, but also lack of a guideline for the conduct of the facility. Saemmul Hospice has keenly felt the necessity of more facility hospices and has interchanged experiences and informations with people interested in hospice. However, the number of facilities has fallen short of one's expectations, and many problems have been revealed in order to maintain the operation. This paper was written in order to improve these atmospheres and to help more terminally ill cancer patients properly. This paper clarifies in detail the principle of management, the method of practice in each departments of Saemmul Hospice, expected effects and supplemental items. We try to provide concrete and practical informations and to help extensively for all peoples who are to begin or currently working. 1.Facility: It secures, maintain, and manage the hospice environment for all around care of patients effectively. 2.Education and Volunteer: It trains and manages hospice volunteers devoted to hospice. 3.Financial: It manages donation by healthy soul with an effective method. 4.Administration and Organization: It executes the administration efficiently and constitutes the organization to operate. 5.Medical and Nursing: It offers the maximum professional supports to a hospital. 6.Medicine and alternative medicine: It improves the quality of life of patients by medical and pharmaceutical approach and by other possible methods available. 7.Nutrition: It helps patients to have diets in accord with the order of the creation. 8.Belief: It offers spiritual care which allows the profound relationship with God. 9. Funeral ceremonies: Funeral ceremonies may heal grieves of families faced with their deaths. 10. Bereaved families: It supports the families after the deaths of patients. 11.Reception and consultation: It seeks to help the patients who meet the purposes for which Saemmul Hospice is established. 12.Publication: It allows publicity activities for Saemmul Hospice. Facility hospice programs are able to overcome the disadvantages that the other type of the hospice possess, like as the economic burdens of the families, and the patients' losses of comforts of home after being transferred to a hospital. Facility hospice can provide home atmosphere with professional manpower and facilities like hospital to the patients. Therefore, it can also improve patients' qualities of life and make them comfortable death. We anticipate that the hospice program in Korea would be more active to let more people be indebted to maintain the nobel human dignity and to cross beautifully in the most painful process of dying in the journey of their lives.

<P> Mepivacaine is an aminoamide local anesthetic with an intermediate duration that intrinsically produces vasoconstriction both in vivo and in vitro. This study investigated the arachidonic acid metabolic pathways involved in mepivacaine-induced contraction, and elucidated the associated cellular mechanism with a particular focus on extracellular signal-regulated kinase (ERK) in endothelium-denuded rat aorta. Isolated rat thoracic aortic rings were suspended for isometric tension recording. Cumulative mepivacaine concentration-response curves were generated in the presence or absence of the following inhibitors: quinacrine dihydrochloride, nordihydroguaiaretic acid, phenidone, AA-861, indomethacin, NS-398, SC-560, fluconazole, PD 98059, and verapamil. Mepivacaine-induced ERK phosphorylation, 5-lipoxygenase (5-LOX) expression, and cyclooxygenase (COX)-2 expression in rat aortic smooth muscle cells were detected by Western blot analysis in the presence or absence of inhibitors. Mepivacaine produced tonic contraction in isolated endothelium-denuded rat aorta. Quinacrine dihydrochloride, nordihydroguaiaretic acid, phenidone, AA-861, NS-398, PD 98059, and verapamil attenuated mepivacaine-induced contraction in a concentration-dependent manner. However, fluconazole had no effect on mepivacaine-induced contraction. PD 98059, quinacrine dihydrochloride, nordihydroguaiaretic acid, AA-861, phenidone, and indomethacin attenuated mepivacaine-induced ERK phosphorylation. Mepivacaine upregulated 5-LOX and COX-2 expression. These results suggest that mepivacaine-induced contraction involves ERK activation, which is primarily mediated by the 5-LOX pathway and in part by the COX-2 pathway. </P>

Direct Photo-Patternable Organic-Inorganic Hybrid Gate Dielectric for Organic Thin-Film Transistors: Influence of the ZrO2 Content

Seong Hui Lee,정선호,Jun Kwang Song,문주호 한국물리학회 2009 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.54 No.2

An inorganic-organic hybrid gate dielectric was synthesized in a sol-gel reaction. 3-methacry loxypropyltrimethoxysilane serves as both an organosiloxane network former and an organic func- tional group whose photo-polymerization can permit negative-type photo-patternability. Addition of zirconium alkoxide leads to the uniform incorporation of ZrO2 distributed in the matrix phase. At 170℃, the obtained hybrid dielectric exhibits a smooth surface structure with an RMS roughness of ~0.25 nm. The dielectric strength of the film was determined to be 1.2~2.3 MV/cm. Increasing the amount of zirconium alkoxide effectively enhances the dielectric constant of the hybrid films from 5.3 to 6.6. The use of the gate dielectric with a high dielectric constant proves to be beneficial for fabricating an organic thin-film transistor. The organic thin-film transistor fabricated using the hybrid dielectric with a high dielectric constant shows a very low threshold voltage close to ~0.4 V without deteriorating carrier mobility.

Enhanced Scintigraphic Visualization of Thyroglossal Duct Remnant during Hypothyroidism after Total Thyroidectomy: Prevalence and Clinical Implication in Patients with Differentiated Thyroid Cancer

Lee, Sang-Woo,Lee, Jaetae,Lee, Hui Joong,Seo, Ji-Hyoung,Kang, Seong-Min,Bae, Jin-Ho,Ahn, Byeong-Cheol Mary Ann Liebert 2007 Thyroid Vol.17 No.4

<P>OBJECTIVE: The exact prevalence and clinical significance of ectopic thyroid or thyroglossal duct remnant (TGDR) in the general population have not yet been fully determined despite numerous case reports. This study was prepared to assess the prevalence of TGDR in asymptomatic subjects during hypothyroidism after a total thyroidectomy for differentiated thyroid cancer (DTC) and to clarify the clinical implication. DESIGN: Tc-99m pertechnetate scintigraphy (Tc-scan) of the head and neck before radioiodine ablation therapy and whole-body and pinhole I-131 scintigraphy (I-scan) after ablation therapy were reviewed for 131 consecutive DTC patients with hypothyroidism after a total thyroidectomy. MAIN OUTCOME: Forty-four among the 131 patients (33.6%) revealed an unexpected linear or focal radioactivity at the anterior midline of the neck, suggesting the presence of TGDR. The Tc-scan and pinhole I-scan were concordant in all cases of abnormal midline neck uptake, although the planar I-scan failed to delineate TGDR due to prominent photon scattering in most cases. Preoperative enhanced neck computed tomography scan was performed in 49 patients and showed no evidence of thyroid glandular tissue separated from thyroid gland in midline of the anterior neck except 1 case. The success rate after radioiodine ablation did not differ significantly between the positive and negative TGDR patients. CONCLUSIONS: TGDR can be frequently observed in scintigraphy of hypothyroid subjects after a thyroidectomy, even when clinically unexpected. Therefore, care should be taken not to confuse the tracer uptake by TGDR with metastatic foci in I- and Tc-scans of patients with hypothyroidism after a thyroidectomy for DTC.</P>
