This study was designed to compare the understanding of ordinary elementary school students and scientifically gifted students about scientists. 473 fourth, fifth, and sixth graders in ordinary elementary schools and 40 students attending scientific educational institutions for the gifted were studied with the help of questionnaires and interviews. The survey showed that there were no significant differences between the two subject groups in relation to the external images of scientists. The subjects turned out to have four fixed external images. The scientifically gifted students had a better understanding of the internal images of scientists than ordinary elementary school students. Both the subject groups turned out to be influenced by the press media and off-campus education, thinking that scientists served as inventors producing something useful in daily life rather than as researchers studying natural phenomena or laws. It was found out that both groups admired Edison. The ordinary students respected Einstein and Jang Yeong-Sil whereas the scientifically gifted students respected Curie, Jang Yeong-Sil, and Nobel. The subjects admired them because of their achievements instead of their backgrounds or individual characteristics.

The purpose of this study was to analyze information about food and nutrition topics presented throughout the television broadcast media, thereby suggest the optimal communication method to give right information to the general public. To perform this study, total sixteen monitoring people were recruited and trained through monitoring practice before and during the study. Five domestic TV channels were selected to be monitored, for six months. For the best efficiency, all the monitoring people were divided into 8 teams based on the regional consideration. The statistical analysis of data was completed using SAS program. The main results of this study are as follows. First, the total reporting cases of information about foods and nutrition were 237, among which about 30% was classified as appropriate and 70% as inappropriate based on the trained monitors' evaluation. Second, the analysis of contents about incorrect informations showed that the insufficient descriptions of terminology and contents were the highest. And insufficient scientific evidences, incorrect contents excessively entertainment-oriented, no provision of alternatives, improper selection of expert advisors were followed. These results suggest that systematical monitoring should be continued to reduce the frequency of incorrect communication thereby give the right information in food and nutrition area to the general public. And there should be a closely cooperated system to provide the professional information to broadcasting production team by establishing the strategic program. In order to do that, most importantly the advisory team should be organized to professionally connect mass media to corresponding specialists. In addition, more educational programs about food and nutrition should be developed provide right information to the general public.

Nowadays increasing use of abdominal ultrasound in routine check-up may increase the detection rate asymtomatic cystic lesions of pancreas. Even through the majority of the cystic lesions of pancreas is pseudocyst, about 10-15% of those lesions are caused by pancreatic cystic tumor. In the pancreatic cystic tumor, especially, mucinous cystic tumor should be exicised due to its malignant potential, while the pancreatic pseudocyst or serous cystic tumon can be observed for a period or treated medically. Several clinical, radiological, biochemical and pathologic guidelines have been developed in order to distinguish among them. Among pancreatic cystic tumors, mucinous cystic adenocarcinoma is very rare and accounts for only 1% of all pancreatic neoplasms. Unlike extremely poor prognosis of pancreatic adenocarcinoma, mucinous cystic adenocarcinoma has an indolent course and shows a good prognosis after its curative resection. Recently we experienced a 69-year-old woman who had a mucinous cystic adenocarcinoma of the pancreas. We report this case with a review of literature.

The purpose of this present study was to investigate the effect of VitaminQ supplementation on antioxidant enzyme activities and cardiorespiratory function following prolonged exercise in trained triathlers. Male 14 healthy college students of trained triathlers participated in exercise sessions. The subjects were divided into 2 groups, as Non-supplement(NS) or VitaminQ supplement(VQ) groups. VitaminQ subjects were participated in two exercise sessions: an initial prolonged exercise(swim 750m, running 10㎞) and 70%V O2max treadmill running exercise. The Non-supplement group fed normal diet. VitaminQ group adminstated 90㎎/day for 4weeks. Venous blood samples were drown from the forearm antecubital vein pre-supplement, pre-exercise and immediately post-exercise. The results of this study can be summarized as follow: First, the SOD activity of RBC was not changed, while the GPx, GR or GR/GPx activies of Hb were significantly increased following prolonged exercise with CoQ10 supplementation. Second, 70%VO2max treadmill running exercise increased significantly the V O2max and VE, but the heart rate significantly decreased. In conclusion, the present results clearly show that the VitaminQ supplementation gave rise to increase the GPx or GR activies and to improve the cardiorespiratory function.

Kim, Kyung Hoon,Park, Jinhee,Yoo, Ji Yeon,Kim, Min Jae,Kim, Il,Rhee, Chin Kook,Lee, Hea Yon The Korean Academy of Tuberculosis and Respiratory 2015 Tuberculosis and Respiratory Diseases Vol.78 No.2

Lymphomatoid granulomatosis (LYG) is an angiocentric and angiodestructive neoplastic proliferation of B and T lymphocytes commonly involving the lungs. Epstein-Barr virus is commonly detected in lesional cells. We report a case of a 54-year-old female with underlying monoclonal gammopathy of unknown significance who presented with a 4 week history of dyspnea and cough. Computed tomography scan of the chest showed multiple lung nodules as well as endobronchial narrowing causing atelectasis at the left upper lobe. Bronchoscopic findings revealed obstruction at the lingula segment due to endobronchial mass as a rare presentation. Bronchoscopic biopsy was diagnosed with LYG grade 1. After treatment, the endobronchial mass and lung lesions were completely resolved. However, the patient eventually evolved to malignant lymphoma after 1 year.

Astroglial loss and edema formation in the rat piriform cortex and hippocampus following pilocarpine-induced status epilepticus

Kim, Ji-Eun,Yeo, Seong-Il,Ryu, Hea Jin,Kim, Min-Ju,Kim, Duk-Soo,Jo, Seung-Mook,Kang, Tae-Cheon Wiley Subscription Services, Inc., A Wiley Company 2010 Journal of comparative neurology Vol.518 No.22

<P>In the present study we analyzed aquaporin-4 (AQP4) immunoreactivity in the piriform cortex (PC) and the hippocampus of pilocarpine-induced rat epilepsy model to elucidate the roles of AQP4 in brain edema following status epilepticus (SE). In non-SE-induced animals, AQP4 immunoreactivity was diffusely detected in the PC and the hippocampus. AQP4 immunoreactivity was mainly observed in the endfeet of astrocytes. Following SE the AQP4-deleted area was clearly detected in the PC, not in the hippocampus. Decreases in dystrophin and α-syntrophin immunoreactivities were followed by reduction in AQP4 immunoreactivity. These alterations were accompanied by the development of vasogenic edema and the astroglial loss in the PC. In addition, acetazolamide (an AQP4 inhibitor) treatment exacerbated vasogenic edema and astroglial loss both in the PC and in the hippocampus. These findings suggest that SE may induce impairments of astroglial AQP4 functions via disruption of the dystrophin/α-syntrophin complex that worsen vasogenic edema. Subsequently, vasogenic edema results in extensive astroglial loss that may aggravate vasogenic edema. J. Comp. Neurol. 518:4612–4628, 2010. © 2010 Wiley-Liss, Inc.</P>

Sexual Maturity and Early Life History of the Mudskipper Scartelaos gigas (Pisces, Gobiidae): Implications for Conservation

Kim, Jin-Koo,Baek, Hea-Ja,Kim, Jae-Won,Chang, Dae-Soo,Kim, Joo-Il The Korean Society of Fisheries and Aquatic Scienc 2011 Fisheries and Aquatic Sciences Vol.14 No.4

Scartelaos gigas is an amphibious mudskipper species that inhabits mud flats in Korea, China, and Taiwan. This fish is at risk of extinction because of its very restricted habitat and overexploitation. Information about this fish's reproductive characteristics is needed for species conservation. The sexual maturity and early life history of S. gigas were investigated through histological methods and direct observation of eggs in the wild, respectively. In total, 560 individuals of S. gigas were collected with the aid of fishermen from March 2003 to October 2003 at Jung-do Island, southwest Korea. Through microscopic observations of gonadal development, it was determined that S. gigas of both sexes were immature in April, but began to reach maturity in May, and were then fully mature by June, which was maintained until July. In August, some female fish developed early oocytes, but by September oocytes were observed to have degenerated and had been absorbed. Spawned eggs were elliptical and had an average size of 1.37 mm (long axis) by 0.69 mm (short axis). The newly hatched larvae (3.03 mm total length, TL) had an open mouth and anus, two melanophores near the anus, and one large melanophore between the 18th and 19th myomeres. The larvae (3.18 mm TL) showed absorption of the yolk and oil globule within 5 days after hatching and became prelarvae. This species should be considered vulnerable or conservation-dependent, and thus parental fish need to be protected from fishermen during the main spawning season (June).

정해용(Hea Yong Jeong),안대균(Dae Gyun Ahn),천영일(Yeong Il Cheon),김기성(Ki Seong Kim),전봉근(Bong Geun Jeon),박태학(Tea Hak Park),김홍일(Hong Il Kim) 대한기계학회 2020 대한기계학회 논문집. Transactions of the KSME. C, 산업기술과 혁신 Vol.8 No.1

소형 제품 및 의학 인체 제품을 만들기 위해서 3D 프린팅 공정을 활용하여 복잡한 형상 및 경량화를 위한 연구가 많이 진행되고 있다. 소형 및 형상이 복잡한 제품을 PBF 방식이 유리하며, 대형이며 형상이 단순한 제품은 DED 방식이 유리하다고 알려져 있다. 지금의 3D 프린팅 사업은 ABS 수지나 플라스틱 제품 제작이 일반화되어 있으나, 금속 제품은 제한적으로 현업에 적용되고 있으며, 미래에는 이러한 공정을 활용하여 적재적소에 사용될 것이다. 이에 선도적으로 판재 소재나 단조 소재로 제작하던 구조용 제품의 3D 프린팅 PBF 방식으로 개발 및 구조용으로 사용 가능성에 대하여 고찰하고 현업에 적용하는 것을 검토하고자 한다. As the industry develops, many researches are being conducted to make complex shapes and lightweight using 3D printing process to make small products and medical human body products. It is known that the PEB method is advantageous for a small-sized and complex-shaped product, and the DED method is advantageous for a large-sized and simple-shaped product. In the current 3D printing business, the production of ABS resin and plastic products is common, but metal products are limitedly applied to collaboration and will be used in the right place in the future by utilizing these processes. In this paper, we will consider the possibility of using 3D printing PEB method for structural products manufactured by using plate material or forging material for development and structural use.
