The clinical spectrum of infections caused by non-typhoid Salmonella spp. includes gastroenteritis, enteric fever,bacteremia, and extraintestinal localized complications, especially in immunocompromised hosts. Here we report a patient with severe aplastic anemia developing left iliopsoas abscess caused by non-typhoid Salmonella (NTS),which was successfully treated by prolonged antibiotic treatment and repeated debridement. Our data indicate that aplastic anemia is a risk factor for infection caused by NTS.

( Chin Min Lin ),( Chi Ta Wu ),( Li Chin Chen ) 전북대학교 인문학연구소 2014 건지인문학 Vol.12 No.-

This research aims to compare the similarity and difference in vocabulary strategy use between EFL and CSL learners. There were 217 subjects in Taiwan participated in this study. Vocabulary Learning Strategy Inventory was conducted to identify the strategies for both EFL and CSL learners used to learn English vocabulary or Chinese characters. SPSS is employed to analyze the data collected. The results showed that two of the strategies used by EFL and CSL learners are different and the other 16 strategies used are the same. The outcome revealed that vocabulary learning is similar across these two languages. Thus EFL and CSL teachers can facilitate learners to apply their first language vocabulary learning strategies and transfer those to second/foreign language learning. In the meantime, teachers ought to pay attention to the fundamental differences between the two languages to help learners to seize the vocabulary learning strategies based on the language features specifically.

This research aims to develop a scale to explore student`s atti-tude toward creative English teaching in Taiwan. Three hundred and nineteen subjects participated in this study. Exploratory factor analy-sis was employed to test the internal consistency of scale and reli-ability test was conducted to measure the internal consistency of the items. The preliminary 32-item scale was scrutinized by a specific set of criteria to develop the final version of the scale. Four items were removed from the scale because they did not meet the requirements. The final scale consisting of twenty-eight items were examined by the same procedure and five factors were extracted from this scale. All of the items in the final scale met the following criteria: Eigen values were larger than 1, factor loadings were larger than.3; item-total cor-relations were larger than.5, and Cronbach`s a value was larger than .6, Teachers and researchers can employ this scale to uncover stu-dents` attitude toward creative English teaching, and modify their teaching methods accordingly.

Unusual Exchange Bias Effects Induced in NiFe/Mn Thin Films via Ion-beam Bombardment: Superlattice vs. Nanocomposite

Chi-Hsin Liu,Chin Shueh,Tien-Chi Lan,Ko-Wei Lin,Wen-Chen Chen,Te-Ho Wu,R. D. Desautels,J. van Lierop 한국물리학회 2013 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.62 No.12

The interplay between interlayer coupling and exchange bias coupling in [NiFe/Mn] multilayerbasedthin films was investigated by using ion-beam bombardment during deposition to control theconfigurations from superlattice to nanocomposite or hybrid-structured thin films. Results showedthat well-defined interfaces in the superlattice [NiFe/Mn] thin film exhibited an interlayer couplingbehavior. In contrast, an enhanced coercivity was observed in the nanocomposite [NiFe-Mn] thinfilm. However, the hybrid [NiFe-Mn]/[NiFe/Mn] thin film with an intermixed NiFeMn alloyed filmcomponent gave rise to unusual positive exchange bias coupling.

The construction of a multiple intelligences inventory

( Chin Min Lin ),( Chi Ta Wu ) 전북대학교 인문학연구소 2012 건지인문학 Vol.8 No.-

The purpose of this research is to construct an inventory to explore Taiwanese students` multiple intelligences. Four hundred and nineteen subjects participated in this study. The validity of the inventory was examined by exploratory factor analysis and the internal consistency was examined by reliability test. A set of criteria were used to extract the preliminary 64-item inventory to derive the final 42-item inventory. These criteria included four parts: Eigen values were greater than 1, factor loadings were greater than .3; item-total correlations were greater than .5, and Cronbach`s α values were greater than .6. This proposed inventory can be used to assess students` multiple intelligences more efficiently and effectively teachers then can plan and arrange their instructions accordingly.

Mathematical Analysis of the Parallel Packet Switch with a Sliding Window Scheme

Liu, Chia-Lung,Wu, Chin-Chi,Lin, Woei The Korea Institute of Information and Commucation 2007 Journal of communications and networks Vol.9 No.3

This work analyzes the performance of the parallel packet switch (PPS) with a sliding window (SW) method. The PPS involves numerous packet switches that operate independently and in parallel. The conventional PPS dispatch algorithm adopts a round robin (RR) method. The class of PPS is characterized by deployment of parallel low-speed switches whose all memory buffers run more slowly than the external line rate. In this work, a novel SW packet switching method for PPS, called SW-PPS, is proposed. The SW-PPS employs memory space more effectively than the existing PPS using RR algorithm. Under identical Bernoulli and bursty data traffic, the SW-PPS provided significantly improved performance when compared to PPS with RR method. Moreover, this investigation presents a novel mathematical analytical model to evaluate the performance of the PPS using RR and SW method. Under various operating conditions, our proposed model and analysis successfully exhibit these performance characteristics including throughput, cell delay, and cell drop rate.

Evaluation of Malignancy Risk of Ampullary Tumors Detected by Endoscopy Using 2-[18F]FDG PET/CT

Objective: We aimed to investigate whether 2-[18F]fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (2-[18F]FDG PET/CT) can aid in evaluating the risk of malignancy in ampullary tumors detected by endoscopy. Materials and Methods: This single-center retrospective cohort study analyzed 155 patients (79 male, 76 female; mean age, 65.7 ± 12.7 years) receiving 2-[18F]FDG PET/CT for endoscopy-detected ampullary tumors 5–87 days (median, 7 days) after the diagnostic endoscopy between June 2007 and December 2020. The final diagnosis was made based on histopathological findings. The PET imaging parameters were compared with clinical data and endoscopic features. A model to predict the risk of malignancy, based on PET, endoscopy, and clinical findings, was generated and validated using multivariable logistic regression analysis and an additional bootstrapping method. The final model was compared with standard endoscopy for the diagnosis of ampullary cancer using the DeLong test. Results: The mean tumor size was 17.1 ± 7.7 mm. Sixty-four (41.3%) tumors were benign, and 91 (58.7%) were malignant. Univariable analysis found that ampullary neoplasms with a blood-pool corrected peak standardized uptake value in earlyphase scan (SUVe) ≥ 1.7 were more likely to be malignant (odds ratio [OR], 16.06; 95% confidence interval [CI], 7.13–36.18; P < 0.001). Multivariable analysis identified the presence of jaundice (adjusted OR [aOR], 4.89; 95% CI, 1.80–13.33; P = 0.002), malignant traits in endoscopy (aOR, 6.80; 95% CI, 2.41–19.20; P < 0.001), SUVe ≥ 1.7 in PET (aOR, 5.43; 95% CI, 2.00–14.72; P < 0.001), and PET-detected nodal disease (aOR, 5.03; 95% CI, 1.16–21.86; P = 0.041) as independent predictors of malignancy. The model combining these four factors predicted ampullary cancers better than endoscopic diagnosis alone (area under the curve [AUC] and 95% CI: 0.925 [0.874–0.956] vs. 0.815 [0.732–0.873], P < 0.001). The model demonstrated an AUC of 0.921 (95% CI, 0.816–0.967) in candidates for endoscopic papillectomy. Conclusion: Adding 2-[18F]FDG PET/CT to endoscopy can improve the diagnosis of ampullary cancer and may help refine therapeutic decision-making, particularly when contemplating endoscopic papillectomy.
