Silicone softner(SSN-3) for permanent press(PP) finish was prepared by blending beef tallow hardened oil for improving softness, water, the emulsion, which was synthesized from pentaerythritol monostearate as a softening component and silicone oil KF-96 as a lubricating component. The prepared SSN-3 and the PP finishing resin were applied to PP finishing cotton broad cloth and P/C gingham samples using one bath method. The properties such as crease recovery, tear strength, bending resistance test were tested. The samples treated with SSN-3 and PP finishing resin have improved properties, compared with nontreated samples, those treated only with PP finishing resin, those treated with commercial PP finishing softners and PP finishing resin. Also from the bending resistance test, the two kinds of fabric samples treated with SSN-3 of 3% showed grade 5 and these were good enough in feeling.
악관절내장증의 진단에 있어 Dynamic MRI의 효용

The Magnetic Resonance Imaging has been used widely to evaluate the disk position without any interruption of the TMJ structures, and the Dynamic MRI presenting computed serial imaging or the video-recorded simulation images is thought to be very effective to evaluate the disk position under function. This is to study the correlation between the clinical diagnosis and the findings of Dynamic MRI for the diagnosis of internal derangement of the temporomandibular joints. 30 joints(15 patients) were examined clinically, and the movement of TMJ meniscus was reviewed in the dynamic MRI. The comparative results are as follows : 1. All internal derangements of TMJ disk displacement without reduction were consistent with MRI findings. 2. 5 joints (50%) of disk displacements with reduction could not be confirmed by MRI findings. 3. The disk displacements in MRI were found in 55% of painful joints, 50% of clicking joints, and 70% of the joints with restricted movement. 4. The reliability of MRI for the diagnosis of TMD was evaluated as 77% ; 24 of 30 joints who presented with clinical diagnosis of TMD. 5. MRI is very reliable to diagnose the disk displacement without reduction, but it is rather not so effective to diagnose the early derangement or muscle disorders.
Myristyl 지방족기를 함유하는 제4급 암모늄염에 의한 PET 섬유의 감량가공 효과

MDABM and MDAEW, as a accelerating weight loss agents, were prepared by adding water to myristyldimethylbenzylammonium bromide(MDAB) and myristyldmethylethylammonium ethyl sulfate(MDAE) synthesized. As a result of weight loss finishing of the MDABW and MDAEW with NaOH on PET fiber, the ratio of weight loss of MDABW was very larger than that of MDAEW. This result showed that quaternary ammonium bromide had higher weight loss effect than quaternary ammonium sulfate, and the ratio of weight loss was greatly varied with the kind of quaternary ammonium salts used. In these conditions, proper treatment concentration, treatment time, and treatment bath ration were about 8g/l, 60~90min, and 40:1~50:1, respectively.

<배경/목적> Gastritis cystica profunda (GCP)는 성숙된 선상피가 점막하층까지 침윤하여 다수의 낭종을 형성하는 비교적 드문 질환으로, 대부분 위절제술을 시행 받은 후에 발생한다고 보고되었으나 최근에는 위수술의 과거력이 없는 경우에도 보고되고 있다. GCP와 암과의 관련성에 대해서는 전암성 병변 또는 암주위 병변일 가능성이 제시되었으나 부정적인 견해를 보이는 보고들도 있어 논란이 되고 있다. 이에 연자들은 본원에서 수술 및 내시경

Brunner`s gland hamartomas are rare tumors of duodenum, they are often discovered incidentally during esophagogastroduodenoscopy or upper gastrointestinal series. These tumors arise mainly in the duodenal bulb and can present with gastrointestinal hemorrhage and intestinal obstruction. Most of Brunner`s gland hamartomas are located within the range of the standard esophagogastroduodenoscope. However, they are rarely located below the third portion of duodenum. As well known, the small intestine, including the 4th portion of duodenum, jejunum, and ileum, is relatively inaccessible with routine endoscopy. Thus, the diagnosis of Brunner`s gland hamartoma in these area can be delayed up to several months after onset of symptoms. We report a case of Brunner`s gland hamartoma which was located in the fourth portion of the duodenum and presented as obscure gastrointestinal hemorrhage. Radiologic, surgical, and pathologic appearances are presented. (Korean J Gastroenterol 2004; 43:211-214)
