  • This experiment was designed to study the effects of temperature on the peroxidase isoenzymes of a mesophilic microorganism, Escherichia coli (grown within biokinetic zone). Optimum temperature for the growth of E. coli was $37{\circ}C.$ Three different temperatures, 20, 30 and $40{\circ}C,$ were selected. And the isoenzyme patterns of peroxidase of E. coli, growth respectively at each temperature, were analysed by disc electrophoresis. The sample of 20.deg.C showed 4 bands, that of 30.deg.C, 5 bands and that of 40.deg.C, 6 bands. Two dark bands (higher molecular weight, 56,000 and 54,000) and two light bands (lower molecular weight, 11,500 and 10,000) were constant at all samples. But two intermediate bands (M.W.44,000 and 34,000) were variable ; at $20{\circ}C,$ no banding pattern, one band 9M.W. 34,000) only at $30{\circ}C,$ and at $40{\circ}C$ two bands were appeared. And the shifts of growth temperatures between 30.deg.C and 40.deg.C showed the alteration of the isoenzyme patterns ; the isoenzyme patterns of the smaple of tmeperature shift from $30{\circ}C$ to $40{\circ}C$ were same as that of 40.deg.C and vice versa.

  • Rett syndrome (RS) is a neurodevelopmental disorder characterized by loss of cognitive, motor, and social skills, epilepsy, autistic behavior, abnormal airway patterns, gastroesophageal reflux, nutritional problems, and severe scoliosis. Although girls with RS show normal or near-normal growth until 6-8 months, they lose their skills after that. The anesthetic management of these patients requires care because of all these clinical features. Especially in the postoperative period, prolonged apnea is common and extubation is delayed. In this case report, the effect of using sugammadex was presented in a 16-year-old girl with RS. The patient's all bimaxillary teeth and 4 wisdom teeth were extracted under general anesthesia in one session with minimal surgical trauma and moderate bleeding. Sugammadex can be a rapid and reliable agent for the reversal of the neuromuscular block in neurodegenerative patients.

  • 인공지능 기술이 발전하면서 이미지, 음성, 텍스트 등 다양한 분야에 적용되고 있으며, 데이터가 충분한 경우 기존 기법들에 비해 좋은 결과를 보인다. 주식시장은 경제, 정치와 같은 많은 변수에 의해 영향을 받기 때문에, 주식 가격의 움직임 예측은 어려운 과제로 알려져 있다. 다양한 기계학습 기법과 인공지능 기법을 이용하여 주가 패턴을 연구하여 주가의 등락을 예측하려는 시도가 있어왔다. 본 연구는 딥러닝 기법 중 컨볼루셔널 뉴럴 네트워크(CNN)를 기반으로 주가 패턴 예측률 향상을 위한 데이터 증강 방안을 제안한다. CNN은 컨볼루셔널 계층을 통해 이미지에서 특징을 추출하여 뉴럴 네트워크를 이용하여 이미지를 분류한다. 따라서, 본 연구는 주식 데이터를 캔들스틱 차트 이미지로 만들어 CNN을 통해 패턴을 예측하고 분류하고자 한다. 딥러닝은 다량의 데이터가 필요하기에, 주식 차트 이미지에 다양한 데이터 증강(Data Augmentation) 방안을 적용하여 분류 정확도를 향상 시키는 방법을 제안한다. 데이터 증강 방안으로는 차트를 랜덤하게 변경하는 방안과 차트에 가우시안 노이즈를 적용하여 추가 데이터를 생성하였으며, 추가 생성된 데이터를 활용하여 학습하고 테스트 집합에 대한 분류 정확도를 비교하였다. 랜덤하게 차트를 변경하여 데이터를 증강시킨 경우의 분류 정확도는 79.92%였고, 가우시안 노이즈를 적용하여 생성된 데이터를 가지고 학습한 경우의 분류 정확도는 80.98%이었다. 주가의 다음날 상승/하락으로 분류하는 경우에는 60분 단위 캔들 차트가 82.60%의 정확도를 기록하였다.

  • The contamination status of Vibrio parahaemolyticus in commercially valuable shellfish from the south and west coasts of Korea and the antimicrobial resistance patterns of isolated V. parahaemolyticus were investigated from July through October, 2011. The range of V. parahaemolyticus concentrations in oysters Crassostrea gigas and short neck clams Venerupis philippinarum was <30~290 MPN/100 g and <30~46,000 MPN/100 g, respectively, and greater than 10,000 MPN/100 g of V. parahaemolyticus was detected from 7 of 40 short neck clams. During the survey period, 436 strains of V. parahaemolyticus were isolated (129 from oysters and 307 from short-neck clams) and the antimicrobial resistance patterns of all of the isolates were examined. Antimicrobial resistance against at least one antibiotic was seen in 79.8% of the oyster isolates (103 strains) and 63.8% of the short neck clam isolates (196 strains). The antimicrobial resistance patterns were relatively simple because the antimicrobial resistance of the isolates was simply due to resistance to ampicillin. Only one oyster isolate and three short neck clam isolates showed multiple antibiotic resistance, i.e., resistance against more than four antibiotics.

  • Objective : Choroid plexus papillomas (CPPs) are generally regarded as benign tumors with typical radiologic and pathologic findings. However, they sometimes have unusual findings. We have analyzed radiologic findings and pathologic growth patterns on CPPs. Methods : The study group included 5 male and 5 female patients (age range, 3 months to 58 years : median, 29 years). The study group included 3 pediatric and 7 adult patients. All patients underwent surgery; 9 patients had a gross total resection and 1 patient had a subtotal resection. We analyzed the radiologic findings (location, size, mottle-like appearance, enhancement, calcifications, and hydrocephalus) and pathologic growth patterns (typical papillary, papillary and solid, and papillary and tubular). Results : The median follow-up duration was 21.3 months (range, 4-47.8 months). There were no recurrences after initial treatment. All patients had benign CPPs. Pediatric CPPs were 3.2 cm masses (range, 2.7-4 cm) with homogeneous enhancement and a mottle-like appearance, which pathologically showed the papillary growth pattern. Hydrocephalus was present in all pediatric patients. Postoperatively, subdural hygroma had occurred in two patients. In adults, CPPs were located in the fourth ventricle in 6 patients and suprasellar area in 1 patient. The size varied from 0.5-4.2 cm. Hydrocephalus and calcifications occurred in 3 and 4 patients, respectively. Three patients showed the heterogeneous enhancement without a mottle-like appearance and pathologically showed combined papillary and solid growth in 2 patients and papillary and tubular growth in one. Postoperatively, two patients with large masses had injuries of the brainstem and underwent shunt procedures for aggravation of hydrocephalus. Conclusion : CPPs may show unusual radiologic findings, which preoperatively give the difficulty to be differentiated from other tumors. CPPs with unusual radiologic findings showed the combined pathologic growth patterns.

  • To determine the frequency of past and present obesity among patients with NIDDM and to identify the differences of body fat, blood pressure and C-peptide/glucose ratio according to obese diabetic patients (BMI$\geq$25 kg/$m^2$) and nonobese (BMI<25 kg/$m^2$). Also the final factor is to observe the anthrometric change patterns in the study. Method: The weight at 20 years-old, previous maximal body weight, and acute weight loss were queried. Current height, body weight, BMI, waist & hip circumferences, waist-hip ratio, skinfold thicknesses, blood pressure, fasting blood glucose, and fasting C-peptide were measured in one hundred sixty-seven NIDDM patients. The differences of the parameters ccording to obese and nonobese, and three anthropometric change patterns were analyzed. Result: Results were as follows: 1. 66.5 % of the NIDDM patients had a history of past obesity as assessed by their maximum weight, while only 33.2% of them were currently obese (p's < 0.001). 2. The waist & hip circumferences, skinfold thicknesses, systolic, diastolic & mean arterial blood pressure in obese patients were greater than those of nonobese patients (all p's < 0.001). 3. The waist and the hip circumferences, and skinfold thicknesses (subscapula & triceps) were highest among the obese-obese group. WHR and abdominal skinfold thickness in the obese-obese and obese-nonobese groups were higher than those in the nonobese- nonobese group. Systolic & diastolic and mean arterial blood pressures in the obese-obese group were higher than those of obese-nonobese and nonobese-nonobese groups(all p's < 0.005). 4. The abdominal and subscapular skinfold thicknesses in female diabetic patients were greater than those of male patients (all p's <0.0001). Conclusion: Although most Korean NIDDM patients were previously obese, many of them were not obese during the course of the study. Greater central and upper body adiposicity and higher blood pressure was shown in obese diabetic patients. Also, greater central and upper body adiposicity was demonstrated in female diabetic patients.

  • There are replete numbers of reports which have apparently shown that established patterns of methylation are critical for normal mammalian development. Here, we report expression of the DNA methyltransferases (Dnmts) family during mouse early development. Transcription of Dnmt1o occurs in one-cell and morula stage embryos, whereas Dnmtls transcripts were detectable in all cells and tissues examined during the study. Dnmt3a1 transcript was detected in all cells and Dnmt3a2 transcript was particularly detected in the oocyte and 1-cell stages. Low level Dnmt3b1 transcripts were expressed ubiquitously in oocyte, 1-cell, and preimplantation embryos except $2{\sim}4cell$ stages. Dnmt3b3 transcripts were only detected in E7.5 embryo and ovary. Furthermore, Dnmt31 transcripts were detectable in all cells and tissues examined. Unlike Dnmtl, both Dnmt3a and Dnmt3b proteins existed in the nucleus of preimplantation embryos till the morula stage. These Results suggest that differences Dnmts expression level exist and genomic DNA methylation patterns may be determined partly through differential expression of Dnmts during early development.

  • Tatan is a symbol of kinship and belonging in Scotland and a badge of identity recognized all over the world. Alongside the powerful historical and national resonance to Tartan for Scots it has been borrowed repeatedly by fashion. The pattern compositionof Tartan check is formed as a typical cross stripes that vertical line and hrizontal line meets rectangulary. And its color is much various and rich than other check pattern. So its magnificient spec-tacle that various all kinds of colors is dyed in cloth is second to name. Today we are as likely to meet tartan in a couturier dress as in a kilt or plaid. Tartan is distinctive in colour style and de-sign. It conveys personality ceremony and drama. All these aspects of its character have contributed to tartan being one of the best-known and best-loved fabrics in the world. In other parts of Europe traditional checked patterns declined and disappeared but in Scotland tartan survived strongly jist as the bagpipes also European flourished Due to geographical and cultural circumstances Scots were able to develop and enhance tartan and its remarkable individuality ensured its sur-vival in spite of adverse political and economic pressures. Tartan has been adopted as the national dress of all Scots. Lowland and High-land providing a powerful form of national cultural and personal identity. Whether tra-ditional or a recent creation whether tra-ditional or a recent creation whether a symbol of nationality or a substitute for nationhood tartan is no mean achievement.

  • Three dominant rocky intertidal macroalgae, the fucoids Fucus gardneri and Pelvetiopsis limitata (Phaeophyta) and the red alga Mazzaella cornucopiae (= Iridaea cornucopiae) on the west coast of Vancouver Island, British Columbia, Canada were used in a series of field experiments to examine interspecific interactions. These experiments showed complex patterns which included an interchange of negative (inhibition) and positive (facilitation) interactions depending on neighbor distance. Less fucoid recruitment occurred in the plots with greater percent cover of a turfforming red alga, M. cornucopiae. However, experimentally removing Mazzaella turf (the turf was considered to be "blocking" fucoid recruits or "shading" growing recruits) did not increase recruitment. This result indicated that there may be another factor(s) involved in the survivorship of juvenile fucoids in the turf-removed plots. Morphological differences in adult plants between Mazzaella and the two fucoids resulted in another type of interaction; these began when fucoids successfully settled and grew nearby or within the red algal turf. By monitoring microhabitat at the individual plant level for two years, I found that survivorship of fucoid recruits showed different species-specific patterns. The patterns also varied as the microhabitat changed from Mazzaella turf edge to open space. For F. gardneri, longevity of P.limitata at all distances tested was similar. A reason for greater longevity of F. gardneri individuals at edge microhabitats may be that these sites have one side open to light and nutrients and another site that buffers them from desiccation and wave impact. In the Mazzaella-Fucus interaction, neighbor distance was a key factor in determining whether the outcome of the interaction would be competition or facilitation (or protection). This study provides experimental evidence that detectable biological interactions occur in this upper intertidal algal community where physical conditions are usually severe, and also indicates the importance of small scale examination in understanding macroalgal interactions in intertidal habitats.
