Strongyloidiasis is a parasitic disease caused by Strongyloides stercoralis which exists in two forms : the free living and parasitic forms. It exists in warm, moist climate in areas where there is frequent fecal contamination of the soil. After cutaneous invasion by the filariform larvae, petechial hemorrage, pruritus, papular rashes, edema, and urticaria occur. Infection commonly occurs in the proximal intestine of the gastrointestinal (G-I) tract but may extend from the stomach to the anus. Once the worm is established in the small intestine, the physical findings may include epigastric tenderness to palpation. The mucosal biopsy is an inefficient way of making the diagnosis because the worm is found in the biopsy specimen in only 2% of patients. Gastric strongyloidiasis is rare. We experienced a case of gastric strongyloidiasis diagnosed by the endoscopic biopsy and serologic test for parasite specific IgG antibody by micro-ELISA.

Fungus such as Candida albicans is a normal flora that is frequently found in the oral cavity, gastrointestinal tract, genitourinary tract, vaginal mucosa in a normal person. However, candida can cause opportunistic infection in an immune compromised host. Candidiasis has broad spectrum of disease from mucocutaneous infection to invasive or disseminated infection. But, it is rarely reported that candida is associaed with gastrointestinal tract disease in a healthy adult. The case of gastric ulcer associated with candida particularly in a health adult is reported with relevant literature.

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

The elastomeric impression materials had become increasingly popular. The purpose of this study was to evaluate the effect of thickness on the accuracy of the elastomeric impression materials. After impression trays were fabricated providing 1, 2, 3, 4, and 5mm spaces for the impression materials, the polysulfide, silicone, and polyether rubber base impressions were made with the brass master die and measured immediately and at 24 hours from the start of removal. Measurements were made of the length of the crossbar of a figure H reproduced in the impression fromthe scored surface of the occlusal aspect of the master die. The findings through this study could be summarized as follows: A this layer of elastomeric impression probuced more accurate results than thicker layer. Overall, the thickness on the accuracy of the elastomeric impressions did not produced significant differences between 1 and 3mm. In the polysulfide and the silicone impression, no sighificant differences were found in accuracy between 1 and 4mm immediately, and between 1 and 3mm at 2t 24 hours. at The polyether impression did not produced significant differences between 1 and 5mm. The polyether impression was the most stable, while polysulfide impression was the least stable dimensionally.

Jae‑Jin Sim,Sang‑Hoon Choi,Yong‑Kwan Lee,Sung Gue Heo,Taek‑Soo Kim,Seok‑Jun Seo,Kyoung‑Tae Park 대한금속·재료학회 2021 METALS AND MATERIALS International Vol.27 No.7

Tantalum (Ta) is a heavy refractory metal with an atomic weight of 180.95 g/mol, a density of 16.6 g/cm3, and a high meltingpoint of 3017 °C. With its refractory characteristics, it shows excellent chemical and physical stability as well as corrosionand heat resistance at elevated temperatures. The demand for Ta metal and related compounds is increasing with the expansionof the electronics and chemical industries. The Hunter process was proven to be effective in producing Ta powder in1953. Hunter proposed a method in which potassium heptafluorotantalate (K2TaF7) was reduced by sodium (Na). Thus far,this process has been the primary commercial method to produce Ta powder. In this study, quantitative differences wereanalyzed for diluent selection. Additionally, consideration was given to changes in the caloric value depending on the inputamount of diluents. Finally, the optimum material input and the properties of the prepared Ta were analyzed. Stoichiometricratios of K2TaF7(1 mol), NaCl (6.2–6.7 mol), Na (5–7 mol) were weighed, to perform a metallothermic reduction reaction. After the reaction, the tantalum powder was recovered and the flush process was carried out. After that, it was dried in avacuum atmosphere. Physical properties such as oxygen concentration, PSA, ICP-OES, and XRD of powder were conductedto evaluate the characteristics of Ta powder that was finally manufactured.

이 연구는 초등학교 과학 성적 우수아를 대상으로 과학계발활동 프로그램의 구성 및 적용이 과학탐구능력에 미치는 효과를 분석하였다. 분석결과, 과학계발활동 프로그램을 적용한 학생들은 적용하지 않은 학생들에 비하여 관찰, 측정, 자료해석, 가설 설정, 변인통제의 과학탐구요소가 더 신장된 것으로 나타났다. 따라서 과학계발활동의 운영은 과학탐구능력의 신장에 효과를 기대할 수 있으므로 교육현장에서 과학교육을 보다 다양하고 수준별로 운영할 수 있는 프로그램의 개발 및 적용 방안을 모색할 필요가 있다. This study organized a Science Improvement Activity Program designed for the excellent students in science in 5th and 6th grades. After application the effect of the program on science process skills was analyzed. The Science Improvement Activity Program was applied to the experimental group as a club activity after school during the semester. The results of this study were as follows: First, the students participated in the Science Improvement Activity showed an increase in the science process skills compared with those who didn't. Second, it was found that the students to whom the Science Improvement Activity Program was applied have improved in enhancing their science process elements of observation, measurement, data analysis, forming hypotheses, and controlling variables. It is expected that the development of activity programs and their active application should be done in order for schools to provide science education according to each student's capacity from various angles.

This study was compared pre-operative MRI finding with operative finding on 36 cases with the failed back surgery syndrome (FBSS) retrospectively. The purpose of this study was to determine the accuracy of the MRI on the FBSS including early complications such as hematoma of infection. Of the 51 patients with FBSS, we analyzed pre-operative MRI finding compared with operative finding on 36 cases excluding nonunion, instability, metal failure and pseudoarthrosis who underwent an operation for the FBSS from December 1994 to June 1997. There were 25 men (69.4%) and 11 women (30.6%), aged from 16 to 68 years (average 43.6 years). These were divided into 5 sub-groups and calculated sensitivity, specificity and positive predictability. MRI accuracy in recurred disc was 84%, scar adhesion, recurred or developed stenosis, infection and hematoma 100% each and all, overall accuracy of the MRI 93%, respectively. Average interval of re-operation in FBSS WAS 4.3 years. In the 18 cases (50%), symptoms persist without pain-free interval after first operation. Early complications including hematoma and infection are easily detected with MRI. Especially if patient complains of severe leg pain or neurologic deficit, it is a good diagnostic procedure to check the MRI. The MRI is a useful method for evaluation of most cases of the FBSS, but it has limitations to evaluate recurred disc or scar adhesion only in T1, T2 weighted image. Therefore Gd-DTPA enhancement is necessary for the accurate diagnosis.
