We report a case of actinomycotic infection in epiglottis. Actinomycosis in the head and neck area is relatively rare but extremely rare in the larynx. A 63-year old man presented with continuous discomfort of the throat while swallowing. He had a history of oral injury caused by a fish bone a few weeks prior. Upon Examination with a flexible laryngoscope, a whitish round mass was noted at the lingual surface of the epiglottis. Under local anesthesia, a punch biopsy was performed and showed the typical features of actinomycosis. The mass was removed using a Diode laser under suspension laryngoscope. Additive oral antibiotic therapy was done for 2 weeks. No definite recurrence was noted at the operation site and the patient is now free of disease.

Embedded capacitor technology can improve electrical perfomance and reduce assembly cost compared with traditional discrete capacitor technology. To improve the capacitance density of the $Al_2O_3$ based embedded capacitor on Cu cladded fiber reinforced plastics (FR-4), the specific surface area of the $Al_2O_3$ thin films was enlarged and their surface morphologies were controlled by anodization process parameters. From I-V characteristics, it was found that breakdown voltage and leakage current were 23 V and $1{\times}10^{-6}A/cm^2$ at 3.3 V, respectively. We have also measured C-V characteristics of $Pt/Al_2O_3/Al/Ti$ structure on CU/FR4. The capacitance density was $300nF/cm^2$ and the dielectric loss was 0.04. This nano-porous $Al_2O_3$ is a good material candidate for the embedded capacitor application for electronic products.

Ecological characteristics of phytoplankton communities were investigated biweekly at 6 stations from Feb. 2001 to Feb. 2002 at the lower part of the Han River. During the study, a total of 267 taxa which were composed of 114 green algae, 104 diatoms, 22 blue-green algae, 13 chrysophytes and 2 dinoflagellates were observed. The standing crops of phytoplankton communities were ranged from 1.30 ${\times}10^6$ cells ${\cdot}l^{-1}$ to 37.47 ${\times}10^6$ cells ${\cdot}l^{-1}$. The dominant species were 11 taxa including Pediastrum duplex, Scenedesmus quadricauda in green algae, Osillatoria limosa, Microcystis aeruginosa, Merisomorpedia sp., Phormidium sp. in blue-green algae, and Asterionella gracillima, Aulacoseira granulata, Fragilaria crotonensis, Stephanodiscus hantzschii f. tenuis, Synedra acus in diatoms. Asterionella gracillima and Stephanodiscus hantzschii f. tenuis were abundant at every station from winter to spring. Stephanodiscus hantzschii f. tenuis occupied the highest dominant ratio and standing crop. From summer to autumn, dominant species were Aulacoseira granulata at all stations and blue-green algae such as Osillatoria limosa, Microcystis aeruginosa, Merisomorpedia sp. at some stations. These 4 species were mostly present at the lower stations 4, 5, 6 and very few at the upper stations 1, 2, 3.

This study purports to verify managerial effectiveness of the integrated delivery system(IDS) of Japanese health care institutions through comparing the managerial performance between hospital groups providing with both acute and nursing care and those with acute care only. Data on the managerial performance of 697 hospitals providing with nursing care together and 819 hospitals providing with acute care only were collected from Japanese Central Social Insurance Medical Councils 2001, 2003, 2005, and were analyzed using mean comparison test(t-test) between the two groups. The results revealed that there were significant differences between the two groups in such indicators as ratio of material cost, labor cost, depreciation rate, total margin, operating margin, average number of outpatient per day, average revenue of an inpatient per day, total amount of labor cost, gross revenue per employee, and labor productivity. However, we could not find out any consistent evidence which support the effect of integrated delivery system on the hospital managerial performance. Further discussion was made on the limitation of the study and future research agenda relevant to the topic.

In order to investigate water quality factors controlling chlorophyll-a concentrations, the by-daily monitoring was conducted from February to November 2010 in 4 stations of Masan Bay. Seasonal variability in physico-chemical factors was mainly controlled by freshwater loading as a result of precipitation: chemical oxygen demand, suspended solids and nutrient concentrations rapidly increase during the heavy rainy season, whereas they decrease in the dry season. From late winter to mid spring, phosphorus and silica sources relative to Redfield ratio were probably functioned as limiting factor for phytoplankton flourishing in surface waters, but nitrogen concentration during mid-spring to autumn might be responsible for the increase of phytoplankton biomass. The multiple regression analysis revealed that variations in chlorophyll-a concentration may be strongly correlated with changes of water temperature, chemical oxygen demand, dissolved inorganic phosphorus in spring, and salinity, chemical oxygen demand and precipitation in summer. Consequently, in the Masan Bay, a heavy rainfall event is an important factor to determine changes of biotic and abiotic factors, and in addition the dynamics of chlorophyll- a concentration are strongly affected by changes of hydrological factors, especially water temperature, precipitation and nutrients.

간상피모양혈관내피종은 혈관에서 기원하는 종양으로 간에서 발생하는 가장 드문 육종 중의 하나로서 저등도에서 중등도의 악성도를 가지고 있다. 아직까지 원인은 알려져 있지 않으며 예후 또한 예측하기 어렵다. 발생빈도가 낮고, 불균일한 특성, 다양한 임상경과 등으로 현재까지 정해져 있는 치료지침은 없다. 저자들은 64세 여자 환자에서 우엽에 발생한 간상피모양혈관내피종을 간절제술을 시행하고 22개월 후에, 원발병소인 간내 재발은 없이 골, 흉막, 복강 등으로 간외전이를 보인 사례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Epithelioid hemangioendothelioma is a neoplasm of vascular origin with a low-to-intermediate malignant potential and is one of the rare sarcomas arising from the liver. Its etiology is unknown and its clinical outcome is unpredictable. There is no generally accepted therapeutic strategy because of its rarity and the variable natural course between hemangioma and angiosarcoma. We report a case of a 64-year old woman who underwent hepatic resection due to epithelioid hemangioendothelioma in the right lobe that progressed to extrahepatic metastases of the bone, pleura, and peritoneum 22 months later. However, after resection there was no primary hepatic recurrence. (Korean J Hepatol 2008;14:525-531)
