This work concerns ecological studies on the larvae of the ark shell, Anadara broughtonii(SCHRENCK), in the aea adjacent to Gajyo-do in Jinhae Bay. Marine environmental factors, namely, temperatue, salinity, depth, and tidal current were observed in connection with the larval distributions. Water temperature appeared to be one of the main factors that influence the spawning activity. The numbers of the drifting larvae fluctuated greatly during the study period. The trend, however, was for numbers to be low in early summern, increasing in mid summer, and reaching a peak in late summer, at high bottom water temperature and low bottom salinities. Significantly increased numbers of the drifting larvae were observed during the period in which the bottom water temperatures and salinities were very close to those at the surface. the numbers of the drifting larvae showed a positive relationship with velocities of the water mass within the range of 0∼20 cm/sec. It was also noticed that the drifting larvae were relatively abundant in the area of eddy motion.

Wheat germ agglutinin (WGA) lectin, which binds to human melanoma cell line, was con- jugated with Praecoxin A using 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide as a cross-linking agent. Physical mixture(PM) of WGA and Praecoxin A was also prepared by using a non-specific binding property of Praecoxin A to WGA. The WGA : Praecoxin A ratio in the conjugate and PM was approximately 1:18 and 1:20, respectively. The results of hemagglutination assay and enzyme-linked lectin assay indicated that the conjugate and PM maintained the lectin-like properties of the WGA. The binding ratio of coniugate was about 70% during 4-24 hr but the most of Praecoxin A was released within 24 hr in the carte of PM. These results lead to the conclusion that the conjugate is potentially useful for the formulation of injection that requires targeting for melanoma as well as sustained release at the site.

기후변화에 따른 부정적 영향이 가시화되고, 직접적인 경제적 피해가 현실화되면서 온실가스 배출을 줄여 기후변화에 대응하기 위한 범지구적 노력이 가속화되고 있다. 특히 국가의 온실가스 감축에 기여하고 기업의 지구 온난화 방지를 위한 노력을 소비자에게 보여줄 수 있는 효과적인 수단으로 탄소성적표지 제도가 주목을 받고 있으며, 탄소배출량이 상대적으로 적은 저탄소제품에 대한 관심이 점차 증가하고 있는 추세다. 본 연구에서는 제품의 기존 원료물질을 환경부하가 상대적으로 적은 물질로 대체하여 탄소배출량을 줄인 주방세제의 탄소배출량에 대해 전과정평가(LCA) 기법을 활용하여 산출하였다. 전 과정 평가기법은 환경부의 탄소성적표지 작성지침을 적용하여, 사용단계를 제외하는 제조 전 단계와 제조단계 및 폐기단계 를 조사하였다. 그리고 친환경 제품 설계 도입이 제품 온실가스 배출에 미치는 영향을 파악하기 위해 주방세제의 주요 원료 물질에 대한 변경 전후를 비교하였다. 그 결과 대상 주방세제 주요 원료물질의 온실가스 배출량이 0.47 kgCO₂eq/kg-제품에서 0.38 kgCO₂eq/kg-제품으로 개선됨을 알 수 있었으며, 이는 제품 주요 원료물질의 탄소배출량이 약 9.4% 감소되는 것으로 이 를 통해 연간 약 916톤의 온실가스가 감축되는 효과가 있음을 확인할 수 있었다. As negative effects of climate change have been visualized and its direct damages to economy have been realized, the global efforts to respond to climate change by reducing greenhouse gas emission were accelerated. Korea``s Carbon Footprint Labeling gets a lot of attention as one of the effective methods to contribute to national GHG reduction goal, and for enterprises to show customers how much effort the company put into global warming prevention. Consumers`` interest on low-carbon products has been increasing. This study uses Life Cycle Assessment method to calculate the amount of carbon emission of dishwashing detergent, LG Household & Healthcare, which reduced carbon emissions by using raw materials that has relatively lower environment load. Life Cycle Assessment Method is based on guidelines of Carbon Footprint Labeling, Ministry of Environment, and pre-manufacturing, manufacturing, and disposal phase are included while use phase of the product is excluded from assessment. In order to understand the effects of eco-design on carbon emissions, the dishwashing detergent’s carbon emissions are compared before and after the change of main raw materials. The result shows the improvement from 0.47 kg CO₂eq/kg to 0.38 kg CO₂eq/kg per product, and this means the main raw materials`` carbon emissions could be reduced by around 9.4%, which is equivalent to 916tons of GHG emissions per year.

A chevron rubber spring is used in primary suspension system for rail vehicle. The chevron spring support the load carried and reduces vibration and noise in operation of rail vehicle. The computer simulation using the nonlinear finite element analysis program MARC executed to predict and evaluate the load capacity and stiffness for the chevron spring. The appropriate shape and the material properties are proposed to adjust the required characteristics of chevron spring in the three modes of flexibility. Also, several samples of chevron spring are manufactured and experimented. It is shown that the predicted values agree well the results obtained from experiment.

Purpose: We report two cases of brothers diagnosed with oculocerebrorenal syndrome after binocular congenital cataract surgery. Methods: Two brothers who had undergone surgeries for congenital cataracts showed growth retardation, proteinuria, and generalized tonic seizures. The patients were referred to the pediatrics department and evaluated for systemic diseases and genetic counseling. Results: Two brothers had renal tubular dysfunction characterized by hypercalciuria and hyperphosphaturia. The older brother had multiple microcalcifications on both kidneys, and ischemic injury with general dysfunction of the brain. Genetic analysis of brothers and their mother showed a new mutation of P799L in the region of the chromosome Xq25-26.1 locus. The two brothers were diagnosed with oculocerebrorenal syndrome of Lowe (OCRL). Conclusions: In cases of patients with congenital cataracts, the evaluation of systemic disease including genetic abnormality should be considered whenever systemic symptoms such as growth retardation, proteinuria or seizure are found.
