Lymphoproliferative disorders, manifesting either as a primary lesion or as part of a generalized process, rarely involve the breast. The primary malignant lymphoma of the breast is rare. The cytologic features of this neoplasm have not been reported in Korea thus far. We described a case of primary malignant lymphoma of the breast, as diagnosed by fine needle aspiration cytology (FNAC) in an 84-year-old female. FNAC smears showed high cellularity. The main cytologic feature observed was a carpeting of monotonous, atypical, enlarged lymphoid cells. These lymphocytes showed relatively round elliptical nuclei with some indentation. One or more prominent nucleoli were seen. Biopy from the breast mass revealed diagnostic features of non-Hodgkin's lymphoma, diffuse large B-cell type.

King Oyster(Pleurotus eryngii) is one of the most promising mushrooms produced on the domestic farms. The quality as well as quantity of King oyster is sensitively affected by micro climate factors such as temperature, relative humidity, $CO_2$ concentration, and light intensity. To safely produce high-quality King oysters year round, it is required that the environmental factors be carefully controlled by well designed structures equipped with various facilities and control systems. In this study, we are focusing on carrying out growing experiment to find out reasonable range of each environmental factor together with economic and safe structures influencing on the optimal productivity of king oyster mushroom. The optimal productivity will be evaluated by considering the quality and quantity of mushroom production, energy requirements, facility construction and management cost, etc.

International air transport for cargo services is a facilitator for various trade sectors and, by itself, an important service industry. Although international air cargo industry is expected to grow continuously, industry stakeholders complain about legal constraints in the industry and demand more liberalized regime. From its birth at the beginning of the 20th century, the airline industry was tightly regulated by governments with a strong tradition of protectionism. In the past few decades, however, protectionism in the airline industry has steadily declined. Indeed, the airline industry is largely in the process of liberalization. Interestingly, it has been easier to liberalize air cargo service than passenger service. Indeed, states have traditionally shown far more willingness to provide market access for foreign carriers carrying cargo than passengers. Given the impact of air cargo service in a state's wider economy and own characteristics of cargo services (i.e. air cargo traffic is inherently one-way, unlike passenger traffic, which tends to involve round trips), more liberalized approach is necessary for air cargo services. Among three approaches: bilateral, regional (block-based) and multilateral, it is desirable to adopt a multilateral treaty (a new multilateral all-cargo agreement) so as to harmonize and simplify complicated trade regulations on air cargo services.

Satellite laser ranging (SLR) system which measures the round trip time of laser to satellites is one of the important techniques in space geodesy. SLR system gives a powerful tool to determine the precise orbit of satellites, the center of mass of the Earth, and etc because it provides instantaneous range measurements of millimeter level precision. China Transportable Ranging Observation System (TROS) was built in 1999 and other four SLR stations were founded in China. TROS has been upgraded to the new electronic system capable of KHz ranging since last year, and succeeded in KHz SLR technology. TROS has been operated in KASI headquarter for research of space geodesy since August 2008, which will be operated for 12 months by August 2009. Now ISCEA and KASI keep strong relationship in SLR field.

A PCR-aided monitoring of verotoxin-producing Escherichia coli (VTEC) was performed over the period of 12 months by using fresh feces collected monthly from 5 dairy cows that had been identified as VTEC carriers. The PCR products were confirmed to be verotoxin genes by Southern hybridization using a gene fragment of verotoxin 2 as a probe. Although seasonal variation of VTEC shedding seemed to depend on each cow, several factors may have influenced the frequency of detection. Shedding of VTEC tended to be reduced during grazing from the middle of May up to the beginning of October. Only one cow was positive for VTEC in August. Dry-off was also suggested to have a depressive effect on VTEC shedding, i.e. 3 of 4 dry cows showed no shedding of VTEC. Contrary to these factors, winter or indoor rearing tended to increase VTEC with only 5/24 samples being negative during the period from November to April. Total VFA concentration was higher (p<0.05) in VTEC-positive feces than in VTEC-negative feces, while fecal pH and VFA proportions were not different. Partial sequences of verotoxin genes from feces of 4 VTEC-positive cows were nearly identical (99-100%), suggesting that gut bacteria sharing the same gene were distributed among the cows. The present results indicate that grazing and dry-off could be factors which reduce VTEC shedding, while winter/indoor rearing may be a factor which increases the shedding, possibly through on-farm interactions.

The aim of this study is to get the basic data to design the clothing for the female teachers. In this study, we survey the practice of the wear in the spring and the fall of the 422 female teachers in primary, middle and high school, and their wearing sensation according to clothing construction factors. The results are as follows: first, the female teachers frequently wear blouse and skirt, jacket and blouse, jacket and T-shirts, cardigan and T-shirts in upper wear. Second, most female teachers had troubles in their clothing at work. They had serious troubles in writing on the blackboard, due to the improper form and. length of the sleeves, and the inconvenience of their skirt is due to the improper length, while they go up the strains. Third, the comfortable factors of the female teachers' blouse are as follows; round neck line, soutien and peter pan collar, sleeve attatched bodice with a little loose armhole, $10{\sim}20cm$ under from waist in length, front slit, and fastening bottons. In case of skirt, they perceive A-lined, flared, pleats skirt more convieniently than tight one, which are 10cm under from kneeline in length, side fastening system, back slit.

In Bluetooth version 1.0, the frequency hopping algorithm was such that there was one piconet, using a specific frequency, resolving the frequency depending on the part of the digits of the device clock and the Bluetooth address. Basic pattern was a kind of a round-robin using 79 frequencies in the ISM band. At this point, a problem occurs if there were more than two devices using the same frequency within specific range. In this paper, we proposed a software-based adaptive frequency hopping method so that more than two wireless devices can stay connected without frequency crash. Suggested method was implemented with HDL(Hardware Description Language) and automatically synthesized and laid out. Implemented adaptive frequency hopping circuit operated well in 24MHz correctly.

A spayed female, 8-year-old, maltese, weighing 1.84 kg with a history of acute severe vomiting, anorexia, depression for 2 day was referred. An abdominal mass was palpated with abdominal pain on physical examination. Radiographic findings included two soft tissue density masses in the mid-abdominal cavity and gas dilated colon. Ultrasonographs showed one heterogeneous hypoechoic round mass including intestinal wall. There were loss of normal wall layering and motility and absence of internal lumen of the intestinal wall. And another heterogeneous hyperechoic mass was identified to the medial side of the intestinal mass. Based on clinical signs, image findings, and the result of fine needle aspiration, intestinal obstruction due to alimentary lymphoma was diagnosed. On surgery, a cecal lymphoma and mesenteric lymphadenopathy were confirmed and the cecal mass was resected.

A neutered male, 8-year-old, Pekingese, weighing 4.3 kg with a history of anorexia, sneezing, nasal discharge, and epistaxis for one month was referred. Soft tissue swelling around the nasal bone and small defects of the hard palate with a tiny round dark red mass were found on physical examination. The laboratory tests represented mild leukocytosis. On skull radiographs, soft tissue swelling and osteolytic change of the incisor bone, nasal bone, and maxilla were found. On computed tomography scan images, there was soft tissue attenuating opacity with calcified spots in the bilateral nasal cavities and frontal sinuses. Loss of nasal turbinate pattern and nasal septum was found. And destruction of the insicor bone, nasal bone, maxilla, hard palate, perpendicular palatine bone, and cribriform plate were identified. Nasal malignant melanoma was confirmed by nasal biopsy.

A domestic round robin test(RRT) for the quantitative analysis of minor impurities was performed by a standard procedure and standard reference material. The certified reference material(CRM)s for B-doped Si thin film and analysis specimens and the analysis specimens were prepared by an ion beam sputter deposition method. These samples were certified by inductively coupled plasma mass spectrometry(ICP-MS) with isotope dilution method which il one of the most quantitative methods in chemical analysis. By using an international standard procedure(ISO/DIS-l4237) for the quantitative analysis of B in Si by SIMS, a domestic RRT was performed for these specimens. Although only a few laboratories participated in this RRT, the average B concentration well agreed with the certified value within 2% error.
