Berthierine and Nontronite are firstly identified in the Sangdong tungsten ore deposits. Quantitative and qualitative analyses by EPMA and the studies using X-ray diffraction, transmission electron microscopy, and infrared absorption spectroscopy were done to characterize berthierine and nontronite. The data from berthierine are in good agreement with those from other localities. The structural data of the Sangdong berthierine are consistent with the orthorhombic, pseudo-hexagonal form which is more common in samples with high $SiO_2$ and low $Al_2O_3$ content. Geologic features suggest that the Sangdong berthierine is diagenetic in origin. However, nontronite might be a product of hydrothermal alteration after the tungsten mineralization.

Surgical angioplasty of isolated stenosis of the left main coronary artery(LMCA) restores a more physiologic flow to the myocardium, allows percutdneous transluminal coronary angioplasty (PTCA) of distal coronary stenoses at a later stage, and is a less time consuming and convenient procedure than the conventional coronary artery bypass grafting(CABG) . Between Jul. 1994 and Dec. 1995, 7 surgical angioplasty had been performed. LMCA stenoses involved ostium in 2 patients, middle third in 3, and dis- tal third in 2. In 2 patients, the origin of left anterior descending coronary artery was involved in conjunction with LMCA. T e additional coronary artery stenoses were found in 2 cases. One patient was emergently operated after coronary angiography following his cardiac arrest. LMCA was approached anteriorly in all patients. The pulmonary artery was transected in 3 patients for a better exposure. The onlay patch consisted or autologous or bovine pericardium. There was no postoperative myocardial infarction or mortality. Left ventricular functions were well preserved in all patients. Postoperative coronary angiography revealed widely patent LMCA in 5 cases, and mild narrowing of distal anastomotic sites in 2 cases. Provided that well defined indications are followed correctly, surgical angioplasty can be a safe alternative to conventional CABG.

Objective : This study investigated the effect of a remote sensory integrated family program on the visual seeking and stereotyped behavior of children with autism spectrum disorder. Methods : This study was conducted as a single-subject study, a mid-baseline design for three children with autism spectrum disorder, and the intervention was conducted 4 times a week for 4 weeks. All three children confirmed the changes in visual seeking and stereotyped behavior after the intervention. Results : After the intervention, visual seeking and stereotyped behavior decreased compared with the baseline period. Visual seeking decreased on average after 7.59% at intervention, and stereotyped behavior decreased by 6.81 on average. Conclusion : Through this study, it was confirmed that the remote sensory integration home program is effective in visual seeking and stereotyped behavior of children with autism spectrum disorder. Addionally it is useful as a new intervention method a program that allows parents to participate in the intervention process. and it is emphasized that occupational therapists should create and promote cooperative relationships for children intervention.

The objective of the present study is to design a hull form of a 9.77 ton class trimaran for use as a Pleasure boat around the bay of Gyounggy. The boat will be made of fiber reinforced plastics and equipped with a 650 hp diesel engine with a conventional water jet propulsion system and the maximum speed be 25 knots after fully loaded. In the present study, the optimal configuration such as relative location of outriggers of the 9.77 ton class trimaran is selected and the resistance characteristics are carefully studied through a series of model tests. The general arrangement of the boat are also considered in the final decision of the hull form.

유무선 혼합 망에서 GFR서비스의 최소대역, 효율 및 트래픽 제어를 위한 버퍼관리 기법 등을 유무선 혼합망의 셀기반 네트워크에서 가중치를 높이는 시뮬레이션을 통해 공평성을 입증하는 연구를 한다. GFR서비스는 TCP/IP 패킷의 품질보장과 베스트 에포트 트래픽에 대한 최소의 대역폭 보장을 하며, 가용 대역폭에 대한 공평성 있는 대역할당을 지원해야 하기 때문에 버퍼관리를 통한 셀 폐기와 셀 스케줄링 둥이 중요한 요소이다. 본 논문에서는 유무선 혼합 네트워크에서 MCR을 보장하기 위하여 버퍼의 사용 가능한 영역의 활성 VC에 각 VC가중치를 비례해 할당하는 per-VC 어카운트에 기초한 트래픽 제어의 버퍼관리에 대한 유동적 WBA알고리즘을 제안하고 GFR 서비스의 효율 및 공평성을 유무선 혼합 망 셀 기반의 스위치를 이용하여 시뮬레이션으로 결과를 보인다.

경골어류의 뇌하수체에서는 두 종류의 생식선자극호르몬 (FSH, LH)이 생산되며, 이 호르몬들은 공통적인 α 쇄와 특이적인 β 쇄를 가진다. 연어과 어종들에서, FSH는 난황형성과 정자형성의 역할을 하며, LH는 배우자의 최종성숙을 조절한다. 냉수성 고유어종인 열목어 (Brachymystax lenok)의 멸종을 방지하고 종묘생산을 원활히 하기 위하여 먼저 열목어의 GTHα, FSHβ 및 LHβ 쇄를 cloning하여 염기서열을 결정하였다. 열목어 GTHα, FSHβ 및 LHβ의 cDNA는 산천어의 해당 cDNA와 높은 상동성 (각각 84, 95, 98%)을 보였다. 다음으로 기능적인 생식선자극호르몬을 제작하기 위해서 2개의 쇄를 single-strand로 연결하여 진핵세포를 숙주로하는 시스템에서 생식선자극호르몬을 생산할 수 있는 구조체인 FSHβ-GTHα (235 amino acids) 와 LHβ-GTHα (240 amino acids)를 각각 재조합하였다. 또한 각각의 융합단백질 생산용 구조체의 3'-말단에는 단백질추출이 용이하도록 histidine×6 구조를 첨가하였다. 이상의 단일쇄 FSH와 LH 유전자재조합 산물을 포유동물 유래의 세포 (CHO-K1)에 liposome chemical을 사용하여 유전자도입 후 세포에서 분비되는 단백질을 모니터링하였다. 배지를 부분정제한 후 SDS-PACE로 조사한 결과, LH 재조합 유전자를 도입한 후 48-60 시간째에 약 25 kDa의 단백질로서 관찰되었다. 현재 FSH 재조합 유전자에 대해서도 조사중이며, 향후 이를 재료로 하여 기능형 생식선자극호르몬을 생산하고 추출하기 위한 연구가 계속적으로 수행 될 것이다.

Raw and washed spinaches were tested to evaluate the incidences of Aeromonas hydrophila, Escherichia coli O157:H7, Plesiomonas shigelloides, Pseudomonas aeruginosa, Salmonella spp., Shigella spp., Yersinia enterocolitica, Bacillus cereus, Campylobacter jejuni, Clostridium perfringens, Listeria monocytogenes, and Staphylococcus aureus. Four pathogenic bacteria were isolated from spinach samples, and identified by morphological and biochemical methods, including API and ATB identification systems. Isolates from MacConkey, Cereus Selective, Clostridium Perfringens, and Baird-Parker agar media were in 99.9, 99.8, 99.9, and 97.8% agreements with A. hydrophila, B. cereus, C. perfringens, and S. aureus at the species level, respectively. SET-RPLA revealed, among the five strains of S. aureus isolates, two produced type A enterotoxin. All five strains of B. cereus isolates produced enterotoxin as revealed with CRET-RPLA.
