  • Congenital lobar emphysema is one of the abnormal development of pulmonary parenchyme which may cause respiratory distress in infant. This disease is an unusual condition barely mentioned before 1949, and only 166 cases were reported till 1967 in English literature. This report describes a 13 months old girl who had a congenital left upper lobar emphysema. The left upper lobectomy was the operation for this case and the postoperative course was not eventful, and have been in good condition upto now.

  • A frequency relaying algorithm which is used system separation and load shedding to improve transient stability is proposed. The algorithm can trip the generator and shed load in the abnormal frequency condition. The computer simulations of load flow analysis is used to determine the amount of load to be shed in an under frequency condition. Furthermore dynamic brake energization in the simulation is performed for the control of overfrequency.

  • In order to cope with the occurrence of abnormal operation, rotatory condition monitoring system for guide roller of finishing train in wire rolling has been developed. In this study, proximity sensor and its holding devices that could overcome severe in-situ measurement conditions was designed and MMI software using C++ was programmed. Performance of the developed system turned out to be good enough as results of in-line test for POSCO #3 wire rolling mill. It is expected to contribute to prevent the cobble and the grade-down of products caused by the abnornormal operation of guide rollers.

  • The oxygen distribution at steady state is analyzed mathematically in a hexagonal cylinder. The domain is penetrated by parallel cylindrical capillaries of different oxygen squirt. Asymptotic solution is used to determine the effect of axial diffusion. Oxygen concentration profiles are displayed at some positions of capillary-beds. At the venous end some tissue areas suffer from a shortage of oxygen.

  • Mammalian cell cycles are tightly regulated by cyclins, cyclin dependent kinase (CDK), Retinoblatoma (Rb) protein, and cellular CDK inhibitors (CDKI). Cyelin dependent kinases (CDK) are key enzymes regulating eukaryotic cell cycle. And also it is recognized that the abnormal increase of CDK activities is one of the common events in human cancer and CDK inhibitors have therapeutic values in cancer treatment. Until now it is known that over 10 different CKDs participate in cell cycle regulation. (omitted)

  • HDAC and HAT (histone acetyltransferase) are involved in co-regulation in chromatin remodeling and the functional regulation of gene transcription. Abnormal recruitment of HDAC is related to carcinogenesis. Thus, the identification of potent histone deacetylase (HDAC) inhibitor has been considered as very intriguing approach for development for cancer chemotherapy. More recently, anti-inflammatory activity of SAHA cytokines was reported via reduction of proinflammatory cytokinres in vitro and in vivo. (omitted)

  • In mammalian species, CpG dinucleotides are highly methylated with 60-90% methylation at the 5-position of cytosine. The pattern of DNA methylation in a cell dramatically affects the function of the DNA by switching genes on or off. Abnormal methylation events occur during aging and in the development of many cancers. Methylated CpG was reported recently to affect the reactivity of agents (mitomycin C and benzo [a]pyrenediolepoxide) that can fromguanine adducts in DNA. (omitted)

  • For high quality storage of agricultural products, temperature, humidity and gas conditions in a storage house should be controlled properly. But most of the low temperature storage house is depending on temperature control. This study aimed to develop an automatic control system for low temperature storage house that can control storage conditions such as temperature, humidity and $CO_2$ gas concentration. The developed system alarms the user, by telephone or beeper, when abnormal condition has occurred. The farmer can also monitor the inside condition of warehouse in his residence, by Internet. From the results of the performance test, the temperature and relative humidity in the warehouse is controlled within the range of ${\pm}0.5^{circ}C$ and ${\pm}2%$, respectively.

  • The damage by Debrisflow is occurring repeatedly recently by influences of abnormal climate changes. To reduce damage of Debris flow, primarily establishes the suitable measures and apply, in order to do that it is important for investigate the actual condition of Debrisflow. However, it is difficult to understand the current situation of Debrisflow phenomenon because the limit of technical development. For the reduce damage by future Debrisflow, have to collect data, analysis and preservation base on real status of Debrisflow disasters. This paper will refer to The Proposal of Debrisflow Investigation development have been applied overseas to the The Proposal of Debrisflow Investigation which already proposed it at these papers with bases. And this paper will suggest currently face objective The Proposal of Debrisflow Investigation to be able to do utilization to a Debrisflow occurrence situation and state and further study analysis(2).
