The causes of pyogenic liver abscess has been known as biliary tract disease or intrabadominal infection but the large proportions of the patients has no apparent underlying disorders. Recently colonic mucosal lesions were reported in patients with cryptogenic liver abscess and it has been suggested that colonic mucosal break may play a role in developing liver abscess in otherwise healthy patients. We experienced a patient of severe recurrent liver abscess complicated with endophthalmitis only 3 months after successful treatment of initial cryptogenic liver abscess and a polypoid colon cancer was discovered by chance. It seems prudent to proceed colonoscopic examination in patients with cryptogenic liver abscess especially when it is recurrent.

Background/Aims: Hyperglycemia is associated with decreased 2-18[F]fluoro-2-deoxy-D-glucose (FDG) uptake by tumorsassessed by positron emission tomography (PET). In this retrospective study we investigated a comparison of standardizeduptake values (SUVs) in patients with primary colorectal cancers who either had diabetes mellitus (DM) or were otherwisehealthy. Methods: The medical records of 397 patients who were diagnosed with colorectal cancer and underwent PETCTbetween January 2006 and December 2012 were analyzed. Eighty patients with DM and 317 patients without DM wereincluded. Clinical characteristics were reviewed and maximal standardized uptake values (SUVmax) were calculated in the primarycolorectal lesions. Results: There was no significant difference between tumor SUVmax in DM patients (10.60±5.78) andthose without DM (10.92±5.44). In addition, no significant difference was detected between tumor SUVmax in DM patients withglycated hemoglobin (HbA1c) levels <8% (10.34±5.17) and those with HbA1c levels ≥8% (10.61±7.27). The maximum size ofthe primary colorectal tumor was associated with SUVmax in a linear regression analysis. Conclusion: The results of this studyshowed that DM did not influence FDG uptake values in colorectal cancer patients regardless of glucose levels. (Intest Res2014;12:146-152)

Background: The aim of this study is to investigate whether alcoholic liver disease (ALD) is associated with the increased risk of advanced colonic neoplasm in patients with ALD. Methods: We analyzed 118 consecutive patients with ALD who performed colonoscopy between January 2000 and December 2013. For each case, age- (±5 years) and sex- matched controls were identified from patients with non-alcoholic fatty liver disease (NAFLD) and healthy controls. Clinical characteristics were reviewed through medical records, colonoscopic finding, pathologic finding, images. Results: The prevalence of colorectal cancer was 6 (5.1%) in ALD patients, 5 (2.5%) in NAFLD patients, 0 (0.0%) healthy control (P =0.007). In addition, the prevalence of advanced colonic adenoma was 18(15.3%) in ALD patients, 17(8.6%) in NAFLD, in 6 (2.8%) healthy control (P<0.001). A case-control study showed that odds for detecting a colorectal advanced neoplasm among ALD patients without decompensated liver cirrhosis were approximately 10.1 times greater than in healthy controls [OR,10.095; 95% Confidential interval(CI), 3.638-28.014; P<0.001) ]. There was no significant difference in the prevalence of colorectal cancer (P=0.428) and advanced colonic adenoma (P=0.876) according to the presence of decompensated liver cirrhosis (LC) in ALD patients. Age is an independent risk factor for detecting advanced colonic neoplasm in patients with ALD [OR, 1.091; 95% CI, 1.025-1.162; P= 0.007]. Conclusions: The yield for detecting advanced neoplasm was significantly higher in patients with ALD than in healthy control. Screening for colorectal neoplasm using colonoscopy is warranted in ALD patients without decompensated LC.

오다연(Da Yeon Oh),임동선(Dongsun Yim) 한국언어청각임상학회 2013 Communication Sciences and Disorders Vol.18 No.3

배경 및 목적: 본 연구는 2-3세 말 늦은 아동과 정상 아동을 대상으로 비단어따라말하기와 문장 따라말하기 수행 능력 및 다양한 변인들 간의 관련성을 살펴보고자 하였다. 방법: 2-3세 말 늦은 아동과 정상 아동 각각 20명씩, 총 40명으로 하였다. 말 늦은 아동과 정상 아동의 비단어따라말하기 수행 능력과 문장 따라말하기 수행 능력 알아보기 위해 이원혼합분산분석(two-way mixed ANOVA)를 실시하였고, 각 집단에서 비단어따라말하기, 문장 따라말하기와 다양한 변인들(생활연령, 수용어휘력검사 점수, 자음정확도)과 상관관계를 알아보기 위해 Pearson 적률상관계수를 구하여 측정하였다. 결과: 첫째, 비단어따라말하기는 두 집단 간 통계적으로 유의하지 않았지만 두 집단 모두 음절길이가 길어질수록 수행률이 저조하여 통계적으로 유의한 차이를 보였다. 문장 따라말하기는 두 집단 간 통계적으로 유의한 차이를 보였으며, 두 집단 내 구문적 난이도에 따라 통계적으로 유의한 차이를 보였다. 다양한 변인들 중 정상 아동의 경우 생활연령과 문장 따라말하기 능력이 비단어따라말하기 수행과 유의한 상관을 보였으며, 말 늦은 아동의 경우에는 자음정확도와 문장 따라말하기 능력이 비단어따라말하기 수행과 유의한 상관을 보였다. 논의 및 결론: 본 연구를 통하여 문장 따라말하기에서만 말 늦은 아동을 선별할 수 있어, 비단어따라말하기보다 문장 따라말하기가 더 민감하게 말 늦은 아동을 선별할 수 있는 선별 검사도구임을 확인할 수 있었다. Objectives: The purposes of this study were to compare the non-word repetition and sentence repetition performance in late talkers compared to normal children, and to investigate the correlation among non-word repetition, sentence repetition and various other factors. Methods: A total of 40 children composed of 20 late talkers aged from 2 to 3 years old and 20 normal children participated in this study. Results: The results were as follows: a 2-way mixed ANOVA result at each syllable length showed that there was no significant difference on the non-word repetition performance between late talkers and normal children. However both group exhibited a word length effect: as the length of non-words increased, children's performance (percent accuracy of repeating non-words) decreased. On the sentence repetition task, normal children significantly outperformed late talkers. Correlation analysis showed that the non-word repetition performance was significantly correlated with chronological age and sentence repetition performance in normal children. However, in late talkers the non-word repetition performance was significantly correlated with the percent of correct consonant on a standardized articulation test and sentence repetition performance. Conclusion: These results suggest that the sentence repetition performance may be more reliable than the non-word repetition task for accurately identifying late talkers.

This study intends to analyze the relative influence and causal effects of the factors that affects allowance management behavior in teenage consumers by surveying middle school students in Jeju region. The study’s results will provide reference material for identifying the spending patterns of teenage consumers in Jeju region and help develop a consumer education program to promote better allowance management behavior in teenage consumers. The data were collected from 616 7th to 9th grade students in middle schools across the Jeju region. For the analysis of the data, techniques such as frequency and percentage, t-test, ANOVA, multiple-range test by Sheffe, and a path analysis using the SPSS 18.0 program were utilized. The main findings of this study are as follows. First, the allowance management behavior of teenage consumers was better where teenage consumers had bank accounts, where the household income was higher than average, where the level of satisfaction with the allowance amount was high, where the level of consumer socialization with parents and school was high, and where a sound allowance management attitude and skill was present. Second, the factor that had the most causal effect on allowance management behavior was the skill in managing allowance, while self-esteem had the biggest indirect effect. In addition, gender, the presence of a bank account, and consumer socialization with parents, mass media and school had not only a direct impact on allowance management behavior but also had an indirect but significant impact through their effect on allowance management attitude and skill. Although household income, the awareness of the need for education of allowance management, and self-esteem did not have a direct significant impact on the allowance management behaviors of teenage consumers, these factors had an indirect significant impact on behavior through allowance management attitude and skill, which are consumer socialization factors. Such results showed that consumer socialization with parents, mass media and school and allowance management attitude and skill are all mediating factors in the allowance management behavior of teenage consumers.

Thromboembolic events are rare among systemic complications of inflammatory bowel disease; however, they are a significant cause of mortality when they occur. Several reports have considered thromboembolic events in patients with ulcerative colitis presenting with venous or arterial thromboembolism, such as cerebral thrombosis, deep vein thrombosis, pulmonary thromboembo-lism, portal vein thrombosis, or mesenteric vein thrombosis. However, increased coagulability related to Crohn`s disease is extremely rare compared with that of ulcerative colitis. We report a case of a 42-year-old man with complicated portal hypertension that occurred due to extensive portal vein and mesenteric vein thrombosis. He had a monozygotic twin brother who was also in re-mission with Crohn`s disease. The patient showed protein C and protein S deficiencies; however, he recovered with early anti-coagulation therapy.

Kim, Da Yeon,Kim, So-Hyun,Ahn, Hye Min,Lim, Sa Rang,Oh, Junsang,Choi, Seulgi,Lee, Hong-Jin,Auh, Joong-Hyuck,Choi, Hyung-Kyoon The Korean Society for Applied Biological Chemistr 2015 Applied Biological Chemistry (Appl Biol Chem) Vol.58 No.1

Highbush blueberries (Vaccinium corymbosum L.) are cultivated worldwide for their fruit with unique taste and potential health benefits. Blueray, Bluecrop, and Spartan are prominent among the various blueberry cultivars. We performed gas chromatography-mass spectrometry (GC-MS)-based metabolic profiling to differentiate the fruits of these three cultivars, and built an optimal partial least squares-discriminant analysis (PLS-DA) model to separate them. Amino acids, fatty acids, organic acids, phenolic compounds, and sugars were identified in the fruits. The optimized PLS-DA model for different cultivars of the fruits was obtained by selecting variables based on a variable importance in the projection (VIP) cut-off value of 1.0. Caffeic acid, aspartic acid, acetic acid, threonolactone, inositol, xylose, glucoside, linolenic acid, mannose, altrose, glycine alanine, and valine were found to be relevant and contributing compounds for differentiating cultivars. In addition, a hierarchical cluster analyses dendrogram pattern was correlated with the PLS-DA. This study suggested that GC-MS-based metabolic profiling coupled with multivariate statistical analysis could be used to differentiate the fruits of three major highbush blueberry cultivars.

A 6 bits 10 MS/s Asynchronous Loop-Unrolled SAR ADC

김다연(Da-yeon Kim),오상원(Sang-won Oh),황현기(Hyeon-gi Hwang),오동렬(Dong-ryeol Oh) 대한전자공학회 2024 대한전자공학회 학술대회 Vol.2024 No.6

We propose a 6 bits 10 MS/s asynchronous loop-unrolled (LU) successive approximation register (SAR) analog-to-digital converter (ADC) with complementary dynamic amplifiers (CDAs). The proposed LU SAR ADC performs comparison operations using both the rising and falling edges of the clock by utilizing CDA. This reduces power consumption of the comparator and clock generator, and halves the number of comparators, thus enhancing the power and area efficiencies. Designed using a 500nm CMOS process, the measured signal-to-noise and distortion ratio (SNDR) and spurious-free dynamic range (SFDR) at 4.77MHz input are 37.8 and 46.5 dB, respectively.
