최근 기후변화로 지난 2009년과 2012년에 강원도 태백시에서는 가뭄으로 인하여 엄청난 피해를 경험한 적이 있다. 또한 가뭄과 장마의 예측은 점점 더 어려워져 가는 실정이다. 특히 태백시의 87일간의 가뭄과 제한급수에 따른 피해액은 일상생활 134억원, 산업부문 338억원, 공공부문 47억원, 정신적ㆍ사회적 피해 1, 430억원 등 총 1, 949억원에 달하는 것으로 분석되었다. 태백시에 또 다른 큰 문제점은 가뭄으로 인한 고랭지 농업 피해로 인한 손실이다. 고랭지 배추를 생산하는 태백시는 우리나라 유일의 고산지역의 도시로서, 고랭지 농업이 특히 발달한 지역이다. 특히 태백 고랭지 배추는 태백시 농산품의 95.9%, 총 경지면적의 86.6%를 차지하고 있으므로, 배추의 생산성이 태백시 농산품 생산성을 대변한다고 할 수 있다. 본 연구에서는 태백시의 공공기관과 고랭지 농업 지역을 직접 방문하여 소규모 빗물 이용 시설에 대한 현황조사 및 시설의 상태를 점검하고 가뭄발생시 고랭지 농업지역의 피해를 최소화 할 수 있도록 소규모 빗물 이용 시설의 적용 방안 및 효과를 분석하였다. Recently, drought and rainy season are getting more serious. It is getting hard to forecast about drought because drought frequency is getting shorter than before. In 2009(winter) and 2012(summer), Taebaek-si was suffered from enormous damage due to the drought. Particularly, in 2009, cost of damage due to drought and restriction on water supply for 87days were estimated daily life sector 134 billion won, industry sector 338 billion won, the public sector 47 billion won, mental and social damage 1, 430 billion won. The other big issue of Taebaek is decrease in products of Highland Agricultural caused by the drought. Highland chinese cabbage which is the most important agricultural product in Taebaek-si account for 95.9% of all agricultural production of Taebaek-si and account for 86.6% of all gross area. For this reason, chinese cabbage of Taebaek-si is tropical agricultural product and is in charge of supply cabbage definitely. It is considered that if small scale rainwater harvesting system would be installed in highland agriculture area, it could reduce damage of drought at low cost and damage of cabbage would be decrease by system. For this study, We have researched regarding current status of Small Scale Rainwater Harvesting System of Highland Agriculture area in Taebaek-si and have compared with the amount of damage and installation cost in case of drought for the beneficial effects of Small Scale Rainwater Harvesting System, flexible supply of water and damage minimization of agricultural products.

Childhood is very important in one s physical and psychological development through the whole life. The development status of childhood exerts an influence upon physical and spiritual health of the future. Especially its development is dominated by environmental conditions. Unlike adults, children have fantastic, clear, and various sensibility. As they always express themselves following their inner desires, we should provide them with children s culture and environment which can satisfy with their desires and promote their intelligence and spirit. As we investigate carefully that how our children live under the rapid changes of modem society, what they want, and how they behave, express and feel, it s necessary to develop the diversified and reasonable play things fit for children s characteristics which can satisfy with their eyelight improving lack facilities and considering what the want, and also can help the development of their physique, language, emotion, acknowledgment and sociality. First, as a plaything to help children s creativity, social development and physical development in a small in a small area, we made it to be used variously. Second, we made it be controlled according to the height and length because children grow up rapidly in their height and weight. Third, as it s users are young. we made it to be assembled easily and mode it with hygienic and strong materials. Fourth. we improved the degree of children s color satisfaction and efficiency, providing various colors to consider their psychology. As they can experience disjointing, jointing, stability and rhythm through children s various playing desires and the basic type of things using the playthings designed like these, their world can be more rightful.

The aim of this work was to examine the production of stress shock proteins by 2,4,6-trinitrotoluene (TNT) in Pseudomonas putida HK-6 which isolated from explosive contaminated sites. The stress shock proteins, which contribute to the resistance of the cytotoxic effect of TNT, were induced at various concentrations of TNT in exponentially growing cultures of P. putida HK-6. Theses responses involved the induction of a 70-kDa DnaK and a 60-kDa GroEL proteins, characterized by SDS-PAGE and Western blot by use of anti-DnaK and anti-GroEL monoclonal antibodies. Survival of P. putida HK-6 with time in the presence of different concentrations of TNT was monitored, and viable counts paralleled the induction of the stress shock proteins in this strain.

Primary small cell carcinoma of the ovary is a rare, aggressive tumor of young women and has two subtypes. The pulmonary type small cell carcinomas of the ovary that resembled small cell carcinoma of the lung and differed from both clinically and pathologically from small cell carcinoma of the ovary, usually associated with hypercalcemia. The histogenesis of the primary ovarian small cell carcinoma has not been established. We have identified two cases of small cell carcinomas primary in the ovary. One has microscopic features of pulmonary type, and the other has hypercalcemic type. Pulmonary type small cell carcinoma patient was a 40-year-old woman. She was admitted due to known ovarian mass. She was well before this episode. Total abdominal hysterectomy and bilateral salpingo-oophorectomy was performed. Gross examination revealed 15cm sized right ovarian mass which was mostly solid with multifocal necrosis. Histologically, the tumor was composed of small to medium sized round cells with scanty cytoplasm, hyperchromatic nuclei, inconspicuous nucleoli, numerous mitotic figures forming large sheets and diffuse pattern. Hypercalcemic type small cell carcinoma patient was a 43-year-old woman. She was also complained of right abdominal swelling and discomfort of 1 month duration. She was received total abdominal hysterectomy due to myoma in 3 years ago. The serum calcium levels was elevated. Right salpingo-oophorectomy and omentectomy was performed. Gross examination revealed 15cm sized huge ovarian mass which was mainly solid with small cystic components and hemorrhagic necrosis. The omentum showed several oval shaped metastatic nodules. Microscopic examination reveals closely packed tumor cells with scanty cytoplasm, vesicular nuclei that contains single nucleoli, and numerous mitotic figures. Many folliculoid spaces are present. Pulmonary type small cell carcinoma patient died 13 months after surgery. Hypercalcemic type small cell carcinoma patient was alive without evidence of disease 2 months after surgery but lost to follow up thereafter.

Infectious diseases imported from other countries have increased as more and more Koreans are going abroad for various purposes. Tsutsugamushi disease from other endemic area such as Southeast Asia is important, because it can occur in any season and eschar may be absent. We report a case of imported tsutsugamushi disease acquired in the Philippines. A patient presented with fever, headache, and maculopapular skin rash. However, eschar was absent. Polymerase chain reaction (PCR) for 56-kDa gene of Orientia tsutsugamushi using buffy coat was positive. Serum indirect immunofluorescent antibody assay was initially negative but became positive with a titer of 1:320 at follow-up, Sequencing analysis revealed the strain to be 100% identical to the TW73R strain identified in Taiwan. After the patient received doxycycline, body temperature normalized in 12 hours. Tsutsugamushi disease is one of the differential diagnoses that should be included for patients with fever who have recently returned from Southeast Asian countries. PCR for O. tsutsugamushi using patient's buffy coat was useful for early diagnosis.

Microbial consortia were screened for their ability to degrade resole at the sole carbon source. Five microbial consortia were derived from a plant site where a biological treatment of liqid waste stream of a manufacturing facility was located. Among the consortia, the test consortium, designated as MS2, displayed approximately 70% degradation of the substrate, 0.1 g of resole per liter, within the first twelve days of incubation but the degradation did not proceed to completion. pH was decreased and resole degradation was inhibited under the conditions. UV-spectroscopy was used quantitatively to monitor the residual concentrations of resole in the present work. UV-scans of spent culture showed that wavelength of maximum absorption was 216nm for resole.

The purpose of this work was to investigate the microbiological distribution and contamination from korean currency that is circulated generally among various kinds of people. Fifty 1,000-won bills were collected by seasons and regions for 18 months. supernatants derived from bills treated by ultrasonicator with .0.8% saline were inoculated and incubated on various selective media such as mannitol salt agar, potato dextrose agar, plate count agar, bismuth sulfite glucose glycine yeast extract agar, luria-Bertani agar. As the results, various kinds of bacteria and fungi including Staphylococcus aureus, Staphyolcoccus epidermidis, Streptococcus mitis, Streptococcus salivarius, Escherichia coli, Enterobacter sp., Salmonella sp., Pseudomonas sp., Candidasp. from 1,000-won bills grew on the solid media. Bacterial contamination was higher in spring and summer compared to winter, whereas fungal contaminatioj was predominated in winter. Especially, 1,000-won bills collected in fish markets and korean traditional markets were heavily contaminated by E. coli, staphylococcus aureus, Pseudomonas sp. Streptococcus sp.,Salmonella sp., and -hemolytic Bacillus. Similar results were obtained from 5,000-won bills and 10,000-won bills as well. In consequence, it was proven that korean currency of bank notes in current use was significantly contaminated by many pathogenic microorganisms.
