Metastasizing mixed tumors [MMT] of salivary glands are inexplicably metastasize maintaining benign histology. There is no pathologic and flow cytometric analysis criteria to predict the metastasis. MMT is known to metastasize by local implantation, vascular and lymphatic embolization after multiple surgery to local recurrences of primary tumor. However, multiple metastasis including cranium and spine occurred even without surgery to the primary tumor in this case. No pathological evidence of malignancy could be found in both primary and metastatic tumor. MMT is considered as an low grade malignancy based on clinical behavior rather than histologic evidence, such as low mortality rate, long delay of metastasis after primary lesion. Cranial metastasis is also extremely rare and only two cases have been reported. We report this unusual case with a literature review.

This study was performed from July to December 1974 to investigate the rates of contamination of distilled water for injection and local anesthetics. 222 vials were sampled from 7 different places of St. Mary's Hospital The samples were cultured for isolation of microorganisms. The results were as follows; 1. Of 222 vials, 11 were Contaminated by 6 types: Staphylococcus epidermis, Bacillus subtilis, Mima polymorph a, Alcaligenes faecalis, Herellea vaginicala and pepto- streptococcus. 2. 5(9.1 %) of 55 vials from surgical wards, 2 (4.2 %) of 48 vials from surgical OPD, and 4 (12,l %) of 33 vials from pediatric wards were contaminated 3. Between rates of contamination of distilled water for injection and local anesthetics and the number of punctures, there was no significant relationship. (CR=1.42 P〉0.1) 4. There was no significant relationship (CR=1.02 P〉0.1) between the rates of contamination of vials and the duration of the first and the last punctures. 5. The ratios of contamination between 75% alcohol and 2% phenol used for disinfection of rubber lids of vials did not show significant difference.

Inadequate pain relief after upper abdominal surgery increases the incidence of pulmonary complications due to the difficulty in coughing and deep breathing. Kvalheim and Reiestad (1984) introduced intrapleural administration of local anesthetic solutions to produce analgesia following cholecystectomy performed through a subcostal incision, unilateral breast surgery and renal surgery. We studied continuous intrapleural administration of bupivacaine and epinephrine, and its effect in controlling pain after cholecystectomy. In 9 patients, an intermittent dosage technique was used. An intrapleural catheter was inserted and 20 ml of 0.5% bupivacaine and 1:100,000 epinephrine was administered. Results were as following: 1) Mean analgesic duration from the initial intrapleural injection to secondary administration of supplementary bupivacaine was 13.5 hours. 2) No specific changes were noted on vital signs and arterial blood gases. 3) Effective analgesia, produced by intrapleural bupivacaine resulted in significant improvement in tidal volume as measured by spirometry. 4) No signs of systemic toxicity and complications were encountered. 5) Intrapleural administration of a local anesthetics after cholecystectomy provides a satisfactory duration of analgesia.

Derivation of modern products from the by gone age has contributed much for the new modern living. It has been generally recognized that the various ethnicities in Borneo with different backgrounds had made Borneo a place of cultural diversity. However as time passed, most indigenous products are no longer in used or are stored in poor condition. Most products nearly aged over a century are still in a good condition with invaluable sentiments. Indigenous product is an artifact that had been designed and used by certain community of people such as tools, clothing, crafts and goods. Each design may have its own identity to the community. Some of the indigenous products which are no longer in use at present are kept by the community as their collections. The research reveals similarities in the interests of indigenous products, concerns and realities of indigenous communities from the different regions. The study suggests that learning about indigenous materials, such as hand-made products and machine-made products is necessary for the local industry to develop a product identity that is distinctly local. Most indigenous products show evidence of connections to old traditions, yet are new to the design market.

Years ago, anthropologists gave no attention to clothing and dress; but in the 1980s, a new research agenda was created placing the body surface at center stage (Tranberg-Hansen, 2004). Now culture is seen as a process created through agency, practice, and performance-no doubt, clothing very much has a human element. Just as important, we now understand that the globalization process has both local and global impact. Highest on this local/global interaction is the process of consumption. Certainly we are not surprised by this when we know that clothes may be inspired from France, tech-packed from New York, sourced from all over the world, produced in China, and sold in shops on the other side of the globe.

인터넷을 기반으로 하는 정보방송 서비스가 널리 확대되고 있으나, 인터넷 프로토콜 고유의 한계로 인해 사용상에 제한이 있다. 본 논문에서는 기지국에 IP 주소변환 기능을 도입한 억세스망에서의 인터넷 방송 기술이 제안되었다. 수신기에 IP 주소가 할당되지 않아도 되며, 사전에 서버의 주소를 몰라도 정보를 수신할 수 있으며, 서버의 부하나 통신망 트래픽이 대폭 감소되는 장점이 있다. 본 기술은 특히 무선 인터넷 지역방송에 매우 적합하다.

Highly significant correlation (p < 0.001) was found between body weight and chest circumference of the local Katjang and cross-bred (local Katjang ♀ ${\times}$ German Fawn ♂ bucks under study. Increase in body length, chest circumference, depth of chest and height at withers (p < 0.001) reflected significantly the increase in body weight of the bucks. At the same age the cross-breds were bigger than the indigenous breed. No significant correlation was detected between body weight and scrotal circumference, or the latter with sperm counts in both buck types under study. However, the fluid portion of the semen increased in acidity and volume, the latter being significant (P < 0.01) in the local Katjangs, with increase in scrotal circumference. Although the effects of body condition on buck libido of both groups were not significant, the reaction time taken to mount the teaser females were significantly diminished (p < 0.001) with better body condition, at least in the local Katjangs. The reaction time gad an inverse, though not necessarily significant, relationship with semen characteristics such as volume, pH (in local Katjangs, p < 0.05), concentration, color (in cross-breds, p < 0.05), agglutination and mass movements in both phenotypes.

This study was carried out to investigated the actual state of rice milling at local milling plants and to find out sources for elevating their milling recoveries in both quantity and quality. At 36 local milling plants located in Gyeongnam and Jeonnam , milling recoveries and head rice recoveries were measured with respect to their different milling systems and rice varieties. Then, the same samples of rice were milled by experimental milling equipments at laboratory, and the two experimental results were compared in order to determine the amount of milling recovery possibly to be increased. The results of this study are as follows ; 1. Milling recoveries of rice at local milling plants were proved to have no relationship with milling systems, and were 68.1% per ent and 72.6percent on an average with new variety and native variety, respectively. 2. The milling recoveries above stated can be elevated 4.5 percent and 2.9percent with new variety and native variety, respectively, by developing and extending technologies of manufacturing and handling rice milling machinery. 3. The head rice recovery of new variety at local milling plants has insignificant differences among milling systems, and was 54.8 percent on the average. With native variety, the recovery by friction type rice polisher was 0.9percent higher than that of friction-abrasive type polisher, and was 64.9 percent on the average. 4. The head rice recoveries of new variety and native can be elevated 5.1percent and 3.9percent, respectively, by the same stimulation above mentioned.

The Istanbul Strait is one of the important waterways in the world. And its southern entrance has a highly congested local traffic. Till now there are several studies regarding how the Istanbul Strait is dangerous to navigate and how those dangers can be mitigated. But there is no study regarding local traffic which is posing great collision risk. In a certain traffic area, marine traffic safety assessment parameters are traffic volume, frequency of collision avoidance maneuver, traffic density, traffic flow and potential encounter, In this paper local traffic volume, traffic flow and potential encounter number of local traffic vessels and possibility of collision are investigated in order to find degree of danger at the southern entrance of the Istanbul Strait. Finally by utilizing those, risky areas are determined for southern entrance of the Istanbul Strait. Results have been compared to a previous study regarding risk analysis at congested areas of the Istanbul Strait (Aydogdu, 2006) and consistency of the results were presented.
