<B>Graphic Abstract</B> <P>The cover shows an image of fully rollable transparent nanogenerators synthesized using chemical vapor deposition grown large-scale graphene sheets as transparent electrodes and piezoelectric ZnO nanorod arrays. Sang-Woo Kim, Jae-Young Choi, and co-workers report on p. 2187 the electrical and structural stability of the nanogenerators, with excellent charge scavenging performance under external mechanical loads such as bending and rolling. This study shows that graphene-based nanogenerators are very promising for self-powered rollable transparent device applications. <img src='wiley_img_2010/09359648-2010-22-19-ADMA201090066-content.gif' alt='wiley_img_2010/09359648-2010-22-19-ADMA201090066-content'> </P>

Strain type of lactic acid bacteria was analysed by PCR and SDS-PAGE. PCR allows the rapid and specific detection of lactic acid bacteria using primers based on 16S rRNA gene-sequences. The analysis of protein pattern on SDS-PAGE can be used to determine the differences among the same or similar species of lactic acid bacteria. Therefore, the complementary use of PCR and SDS-PAGE method is one of simple way to classify the lactic acid bacteria and to compare with genetic analysis.

This paper is the results of experimental and numerical works on analyzing the geotechnical engineering behavior and characteristics of excavated clay slope formed by the method of excavated replacement which is one of treatments in soft soil ground. For the centrifuge model tests, models of excavated clay slope were prepared by remolding the marine clayey soil sampled from the field. Tests were performed with changing the slope to investigate the behavior of them. On the other hand, numerical analyses were carried out to analyze the change of safety factor against instability of slope with time. Changes of pore water pressure, shear strength and displacement were also investigated. As results of centrifuge model tests with slopes of 1:1.5 and 1:3 using the confining body of simulating the effect of excavation, for the case of 1:1.5, slope failure occurred right after remove the confining body whereas relatively small displacements within the range of 3.2mm, implying to maintain the stability of slope, were observed for the case of 1:3 slope. From the results of numerical analyses using the software of PLAXIS to investigate the stability of slope after excavation, the minimum safety factor against slope failure was 1.28 for the case of 1:3 slope. The further researches in the future are required with considerations of build up of static pore water pressures during acceleration of centrifuge, depth of excavation influencing the behavior of the slope and permeability of the slope since excavation of the slope was not simulated well resulted from the limitations of apparatus at the stage of excavation during the centrifuge tests.

Research has been conducted on the polymerization of Nylon 6.6 and its Kinetics has been computer simulated. The experimental results was in good agreement with those of the computer simulation within the average of 11.5%. It was found as the temperature increases and time elapses the molecular weight increased. The physical properties of the polymers improved as the average molecular weight increased.

Hypereosinophilic syndrome is characterized by persistent blood eosinophilia of 1,500/ul or more in the absence of known causes and multiorgan dysfunction by eosinophil-related tissue damage. In Korea, some cases of hypereosinophilic syndrome with hepatic involvement have been described with prolonged benign clinical courses. Most of them were diffuse or multifocal lesions in imaging studies, and a few case presenting as a single mass has been described. Here we report a case of hypereosinophilic syndrome with hepatic involvement in a 65-year-old man who presented with multifocal mass lesions. By abdominal US and CT scan, multiple, ill-defined nodules were detected in throughout the liver. Liver biopsy revealed severe eosinophilic hepatitis, suggestive of hypereosinophilic syndrome. Hepatic mass lesions improved after steroid administration for several weeks.

과잉치는 치배 형성기에 정상 치판의 과도한 증식의 결과로 발생하며 산발적일 수도 있고 유전적일 수도 있다. 발생 빈도는 1~3%이며,2:1의 비율로 남아에게 호발한다. 주로 상악 전방부에서 많이 발견되며, 매복, 영구치의 위치 이상, 정중부 이개, 낭종, 비강으로의 맹출 등과 같은 다양한 합병증을 나타낼 수도 있다. 상악 전방부에서 발견되어지는 과잉치는 치축방향에 따라 위치가 결정되며 상악 전방부 과잉치의 1/3 정도는 역위 매복되어 맹출의 가능성이 없지만, 치낭의 치관 부위가 정상적인 관계로 존재하는 한 과잉치의 이동이 일어날 수 있다. 치아의 이동은 경구개, 소구치 부위, 비강까지도 일어날 수 있다. 또한 전상악 수직고경의 성장으로 시간이 지남에 라 외과적 접근이 어려워질 수 있다. 이에 본 두 증례에서는 역위 매복된 상악 전방부의 과잉치가 구개 측 중앙부까지 이동된 것을 발견하여 외과적으로 제거하였다. Supernumerary tooth develops as a result of abnormal proliferation of the dental lamina during the initiation stage of dental development. It could be a sporadic occurrence or a hereditary transmission. Supernumerary tooth occurs with a frequency of 1 to 3%, Generally, there is a 2:1 preference for boys. It is usually found in the anterior portion of the maxilla and may be associated with complications such as impaction, malposition of permanent teeth, formation of diastema, cysts and eruption into nasal cavity. The position of supernumerary tooth found in the anterior portion of the maxilla is determined by the axis of the tooth. One third of supernumerary tooth in the anterior portion of the maxilla has no possibility of eruption due to its invertedly impacted position. However, as long as the coronal part of the follicle remain intact, migration of supernumerary tooth is possible. The migration may occur into the palate, the premolar region, the sinus or the nasal cavity. Also, growth of vertical dimension of maxilla could make surgical approach difficult as time goes by. For this reason, we have found invertedly impacted mesiodens moved to the vault of the palate in the two cases, and extracted supernumerary tooth surgically.

In Korea, there has been an increasing concern on rickettsiosis as one of most prevailing acute febrile illness, since murine typhus and scrub typhus had not been reported for 2 decades until 1986 and thereafter a few studies were reported on these diseases. A microimmunofluorescence test was used to study antibodies to R. typhi and R. tsutsugamushi in urban and rural inhabitants students, and patiants suspected of leptospirosis or rickettsiosis from 1986 to 1987 in Kangwon-do Korea. 43% of inhabitatnts and 17% of students reacted to R. typhi. Only one inhabitant among inhabitants and students reacted to R. tsutsugamushi. Among 169 patients, 43(25%) reacted to R. typhi, 38(22%) to R. tsutsugamushi and 25(15%) to Leptospira interrogans. Sexual rate(male; female) in murine typhus was 1.7:1, that in scrub typhus was 1:2.2 and that in leptospirosis was 1.5;1. The age ditribution of patients with murine typhus was generally even over 20 years old. But 71% of patients with scrub typhus were over 40 years old. Scrub typhus was most prevailing in female over 40 years old. Murine typhus was relatively more prevailing in Choonchun city than rural area as compared with scrub typhus and leptospirosis. Most of scrub typhus occurred in rural area. Most of each disease occurred between September and November (murine typhus; 93%, scrub typhus; 95%, leptospirosis; 84%) with a peak in October. Scrub typhus considerably occurred not only October(58%) but also November(28%). All patients with scrub typhus were immediately diagnosed by antibody when they visited hospital. 53% of patients with murine typhus were diagnosed when they visited hospital within 7 days after onset of illness, and others were done by second sera obtained 8 days after. The patients in whom IgM was seronegative but antibodies of other class were seropsitive by 20 days after onset of illness, were 14% in murine typhus and 26% in scrub typhus. At least those patients were considered to be infected second. Murine typhus and scrub typhus were suggested to be endemic diseases in Kangwon-do as antibodies of inhabitants and characteristics of patients' sera were considered. By serologic finding of patients with scrub typhus in Kangwon-do, Gilliam was 59'% of etiologic strain of scrub typhus, Karp was 41q% and Kato was none. Most scrub typhus occurred in person to be related to agriculture, but murine typhus was not related to job and occurred more in small city than rural area. Rash was scarcely detected in murine typhus and scrub typhus, and eschar was in 50% of scrub typhus only. Serum transaminase elevated in many patients with scrub typhus and murine typhus. Leukocytosis and abnormal finding in chest X-ray were showed in some patients with scrub typhus but were scarcely in murine typhus.
