Seven specimens of raindrop imprints are discovered from the Late Triassic Amisan Formation of Nampo Group distributed in the Myeongam area of Boryeong-City, Chungcheongnam-do. The raindrop imprints are interpreted to had been formed in lacustrine environments under subtropical humid climate during the lowered period of the surface of the water by temporally or seasonally arid climate. The raindrop imprints are the first finding in the Lower MesozoicNampo Group, Korea.

Cooling seawater of thermal power plant which amounts about 5 cms per 100 MWe has hydro energy of about 3,000 kW at the thermal power plant complex, but this useful hydro energy has not been developed. Therefore, the feasibility study on hydro energy development of three power plants located in the southern and western coast of Korea was performed. Three target power plants are Samcheonpo, Boryeong and Hadong thermal power plant. The design head to discharge cooling water by gravity and the head caused by tidal level in the southwestern coastal area, could be used for the production of electric power. The various alternatives were studied and technical feasibility and economical efficiency were clearly proved.

대한민국 대표 축제로 자리 잡은 보령머드축제의 핵심 프로그램인 머드 셀프마사지 행사의 재미와 다양성을 부여하기 위하여, 색상이 함유된 머드에 관한 연구를 수행하였다. 머드 고유의 낮은 명도를 조절하고자 이산화티탄을 첨가하여 머드의 질감을 유지하면서 색상이 발현되는 이산화티탄의 함량을 실험하고, 결정된 혼합비율에 황색산화철을 첨가하여 색상의 발현도를 색차계, 육안검사, 사용감 등으로 판단하였다. 결정된 색상은 물에 젖음 시 발색정도와 세척상태를 검토하여 보령머드 축제 프로그램인 머드 셀프마사지 행사에 사용하여 축제의 다양성을 높이고 또한 한국의 고유색인 오방색을 나타낼 수 있는 유색머드를 개발하고자 하였다.

This study was conducted to determine the serum cardiac troponin I (cTnI) concentrations in clinically normal (uninfected) Korean Jindo dogs and those infected with Dirofilaria (D.) immitis. Forty Korean Jindo dogs (22 females, 18 males) were obtained from two kennels in the Boryeong area of Chungnam Province and the Daejeon area, Korea. Significantly higher cTnI concentrations were observed in D. immitis-infected dogs than clinically normal dogs. cTnI testing in addition to thoracic radiography, echocardiography, and electrocardiography shows promise as an additional method for diagnosis of heartworm infection.

The KEPCO Research Institute has developed Molten Carbonate Fuel Cell(MCFC) since 1993. Recently, an 125-kW MCFC system was operated at Boryeong thermal power plant, Korea from December, 2009 to March, 2010, This system is composed of an 125-kW stack, mechanical balance of plant (MBOP), and Power Conditioning System. The stack has 200 unit cells of which effective area is 10,000 cm2. Especially, MBOP is mainly made up of ejector and catalytic combustor which help this system to be supplied with cathode inlet gas using anode tail gas and fresh air. After the pretreatment of this system was performed for about 20 days, initial load operation was performed at January. 2010. Moreover, this system had been operated for 3,270 hours.

This study was performed to proof expansion effect of the mortar bar due to Alkali-silica Reaction (ASR) by ASTM C 1260 test. Recently, the failure case of cement concrete pavement by ASR was reported in Korea. Cement concrete structures are caused crack by ASR. The service life of cracked cement concrete structures by ASR will be shorted. In this study, crushed the slate rock producted Chungcheongnamdo Boryeong was caused 0.3% expansion at 14 days due to ASR by ASTM C 1260 test. The particular spectrum showed that the ASR gel was analyzed contents included Si, Na, K, and Ca by EDX (electron dispersive X-ray spectrometer). It was verified that the crushed aggregate was caused expansion by ASR in Korea.

Researchers consider obsessive-compulsive disorder (OCD) to be an anxiety disorder, but it often shows comorbidity with other disorders in the affective spectrum. Epidemiological and clinical studies have shown a strong association between OCD and mood disorders. In addition, some reports show the patients with OCD have attentional-processing impairments regarding emotional information. However, research has not revealed the exact nature and degree to which OCD constitutes an affective problem. In this review, we discuss the affective aspects of OCD and the relationship between OCD and mood disorders.

In this study, three optimization techniques efficiency is assessed for calibration of the GR4J model for streamflow simulation in Selmacheon, Boryeong Dam and Kyeongancheon watersheds located in South Korea. The Penman-Monteith equation is applied to estimate the potential evapotranspiration, model calibration, and validation is carried out using the readily available daily hydro-meteorological data. The Shuffled Complex Evolution-University of Arizona(SCE-UA), Uniform Adaptive Monte Carlo (UAMC), and Coupled Latin Hypercube and Rosenbrock (CLHR) optimization techniques has been used to evaluate the robustness, performance and optimized parameters of the three catchments. The result of the three algorithms performances and optimized parameters are within the recommended ranges in the tested watersheds. The SCE-UA and CLHR outputs are found to be similar both in efficiency and model parameters. However, the UAMC algorithms performances differently in the three tested watersheds.

This study evaluated the external form of Rhodeus notatus TSV (transparent-scaled variant) type identified in Korea for the first time and compared it with that of the normal type. The TSV units newly found on Rhodeus notatus are iii10 of dorsal fin and anal fin iii10, which are similar to that in the normal type, considering the observing coefficient of each part's fins. The external form is, transparent enough to see the red gill filament in the operculum, the spiral digestive organ is observed opaquely, and numerous melanophores are stained at the upper part of abdomen. The coloration and scales are different between TSV type and normal type; however, there is no difference in the external form and meristic character.
