Bacterial endocarditis is a well-recognized complication of prosthetic valve replacement. Postoperative fungal endocarditis of aortitis has been reported with increasing frequency. Aspergillus endocarditis or aortitis following open heart surgery has been reported in several patients. The difficulty in the diagnosis of this type of infection, the problems of therapy of prosthetic valve endocarditis0 and the relative ineffectiveness of antifungal agents account for the high mortality. Recently, we have experienced a patient with aspergillus aortitis after replacement of mitral valve. The diagnosis was finally established by histotogical examination of emboli removed from the femoral artery. The patient died after second open heart surgery for replacement of ascending aorta.

The H.263 Annex I method for the intraframe coding is based on the prediction in DCT domain, unlike JPEG, MPEG-1, and MPEG-2 where the intraframe coding uses block DCT, independent of the neighboring blocks. In this paper, we show the ineffectiveness of H.263 Annex I prediction method by mathematically deriving the spatial domain meaning of H.263 Annex I prediction method. Based on the derivation, we propose a prediction method which is based on the spatial correlation property of image signals. From the experiment and derivation, we verified the proposed method.

The existing Law of fisheries Management of China was firstly established on October 30th, 1986 and revised in October, 2000. The new Law of Fisheries Management provided a basis for introduction of the TAC (total allowable catch) system into China. Introduction of the TAC system is a natural result of the practise of EEZ (exclusive economic zone). In addition, the inability of the traditional fishery management system and the promising results obtained by conductions of TAC system in some countries with advanced fishery also make the introduction of TAC system a necessity, However, the contradictions between the unrealistic introduction of the fisheries management systems, the small-scale operation, higher expense of the conduction and supervision of the systems, and the insufficiencies of human power, financial fund, and scientific technique of the underdeveloped country resulted in the ineffectiveness of the new systems. So this study is to discuss the background and the possibility of TAC system implementation in china. The results of this study showed that many factors restrict the implementation of TAC system into China at present. It will take a long time to practise the new system. meanwhile, reforming and improving the functions of the existing systems to provide a better environment will play an important role in the introduction of the TAC system into china.

Tardive dyskinesia is a syndrome of involuntary hyperkinetic abnormal movements that occurs during or shortly after the cessation of neuroleptic drug treatment. Typically, the movements are choreoatheoid. Other movements such as tics and dystonia may be present. Nonetheless, any dyskinesia seen in a neuroleptic-treated patient is not always neuroleptic-induced tardive dyskinesia. The prevalence of tardive dyskinesia varies widely, which reflects many methodological problems, such as differential diagnosis. symptom fluctuation, masking effect of neuroleptics, validated diagnostic criteria. Of suggested risk factors, only old age has been consistently found to be associated with an increased frequency of tardive dyskinesia. Many hypotheses about the pathophysiolgy of tardive kinesia are proposeed, but time-honored ones are not present. No consistently safe and effective treatments are found. Various treatment modalities signifies the general ineffectiveness of these agents for most patients. In general, reduction or cessation of neuroleptics, if possible, is recommended. Remission or improvemets of tardive dyskinesia after neuroleptics withdrawal usually occurs among most patients within three months.

Purpose: The purpose of this study was to develop the day hospital program for Korean eating disorders patients and to examine the effect of the day hospital program on improving frequency of binging and purging, eating disorders symptoms, self-esteem, and depression. Method: The subjects were 24 binge eaters visited at eating disorders clinic 'M'. They participated in a modified day hospital program based on the Toronto Day Hospital Program. All subjects completed the Eating Disorders Inventory(EDI)-2, Rosenberg Self-Eesteem Scale, Beck Depression Inventory(BDI) at pre and post intervention, and recorded daily food records. Results: In paired t-test analysis, frequency of binging and purging, self-esteem, depression, and 11 sub-scales of EDI-2(drive for thinness, bulimia, body dissatisfaction, ineffectiveness, interoceptive awareness, perfectionism, interpersonal distrust, maturity fear, asceticism, impulse regulation, social insecurity) were significantly improved after treatment. Conclusion: The results of this study suggest that the day hospital program for Korean eating disorders patients may be an effective initial approach to overcoming various eating disorders symptoms. Further studies should investigate longer term outcome data using a larger sample.

In 22.9kV underground distribution system, power cables are provided with multiple-point ground in which each neutral line of the distribution cable(A, B, C phases) and three-wire common grounded at every connecting section. But in such grounding methods, circulating current flows between the neutral wire and grounding wire. And power loss due to circulating current also occurs in all conductors. Therefore it is getting necessary reducing circulating current in underground distribution system. This paper presents improved grounding method to overcome such problems. The proposed grounding method eliminates circulating current in the neutral line effectively and is verified that there is no electrical problem or any ineffectiveness of operating protection systems. These analyses are carried out by EMTP/ATPDraw to compare each grounding methods in steady and transient state. This grounding method suggested in this paper can be applied on real distribution system after field tests considering elimination of circulating current was implemented.

Most of clustering algorithms data to degenerate rapidly on high dimensional spaces. Moreover, high dimensional data often contain a significant a significant of noise. which causes additional ineffectiveness of algorithms. Therefore it is necessary to develop algorithms adapted to the structure and characteristics of the high dimensional data. In this paper, we propose a clustering algorithms CLIP using the projection The CLIP is designed to overcome efficiency and/or effectiveness problems on high dimensional clustering and it is the is based on clustering on each one dimensional subspace but we use the incremental projection to recover high dimensional cluster and to reduce the computational cost significantly at time To evaluate the performance of CLIP we demonstrate is efficiency and effectiveness through a series of experiments on synthetic data sets.

Contrail is a kind of cloud that is formed during the flight by vapor condensation of engine exhaust in a cold atmospheric condition. Owing to the negative effects of contrails on the environment and in military applications, several studies for contrail mitigation had been performed in developed countries. The goal of this research is to design a lab-scale contrail generator, and to validate the contrail mitigation technology suggested by previous studies. The contrail generator was made using superheated vapor and a low temperature wind tunnel. Using this generator, the ineffectiveness of ethanol and surfactant suggested in the previous paper on contrail mitigation was found experimentally.
