  • As the contemporary public consensus prefers individuality to classical things, they have gotten sick of the universality and pursue fashion anew. As a result the new concept of artistic value delivers a shock to ordinary and traditional images. The bizarreness culture of fashion contains two extremes, horror and humor. which make people uneasy but amused by sensuous descriptions. Bizarre things captivate the audience regardless of the violent stimuli. The conversion of aesthetic consciousness is brought accordingly by horror and humor. In this paper, It is discussed that the concept of history of bizarreness and the social effect from its phenomena in current fashion are expressed through the two methods above. The bizarreness phenomena in current fashion is shown as a new hybrid type which has been recreated and came out of the internet. This phenomena has caused abnormal results and ironically mixed products, what was once directness, violence and disgust, are on the other hand enjoyment and amusement. A widening field, the bizarreness phenomenon, as an important implication in which can completely change the current trend, will be on track as a crucial concept representing contemporary cultures.

  • It is a common saying that markov-chain is a special case of probability course. That is to say, It means an unchangeable markov-chain process of the transition-probability of discontinuous time. There are two kinds of ways to show transition probability parade matrix theory. The first is the way by arrangement of a rightangled tetragon. The second part is a vertical measurement and direction sing by transition-circle. In this essay, I try to find out existence of procession for transition-probability applied markov-chain. And it is possible for me to know not only, what it is basic on a study of chain but also being applied to abnormal problems following a flow change and statistic facts expecting to use as a model of air expansion in physics.

  • Spart-ignition engine knock is an abnormal combustion phenomenon originated from auto- ignition of a portion of or the entire end-gas during the later stage of combustion process. And engine knock is accompanied by a vibration of engine cylinder block and a high-pitched metallic noise. Engine knock is characterized in terms of its intensity, its occurrence crank angel and the percentage of engine knock cycles. To characterize engine knock, a precise measurements of cylinder pressure and a statistical analysis of cylinder pressure data are needed. The purpose of this study is to develope a technique to measure engine knock and its characteristics as a function of ignition timing change. A 4-cylinder spark-ignition engine and unleaded gasoline, whose octane number was 94, were used for experiments. To measure engine knock and to analyze engine knock characteristics, cylinder pressure data were sampled by a high speed data acquisition system which was developed in this study. Cylinder pressure data were sampled at each 0.1.deg. crank angle and the number of cycles continuously sampled was 80.

  • Knock and misfire, kinds of abnormal combustion, are highly undesirable effect on the internal combustion engine. So, it is important to detect these avnormal combuition and control the ignition timing etc. to avoid these mal-effect factors in real engine system. In this study, the system which detects the knock and the misfire using by spark plug is presented. This system is based on the effect of modulation breakdown voltage(BDV) between the spark gaps. The voltage drop between spark plug electrodes, when an electrical breakdown is initiated, depends on the temperature and pressure in combustion chamber. So, we can detect knock and misfire that produce changes in gas temperature and pressure (consequently, its density) using by BDV signal change which carries information about the character of combustion.

  • Relapsing polychondritis is an uncommon disorder of unknown etiology. That involves multisystem characterized by recurrent inflammation, degenerative change of multiple cartilaginous structures. The most common clinical manifestation is an auricular chondritis. Other involving systems are joint, nose, eye, larynx, trachea, aorta, heart and kidney. A 26-year-old man who complained of hoarseness and sore throat was referred to the ENT department from internal medicine department. On initial video-laryngoscopic and radiologic examination, there was no abnormal finding. Treatment with high doses of corticosteroid and methotrexate was not effective. Symptoms were aggrevated with dyspnea. Three months later, on video-laryngoscopic examination, bilateral cord fixation with swelling was noted. The radiologic finding showed subglottic stenosis due to collapse of anterior wall of cricoid cartilage. The condition was managed with tracheotomy. We report a case of relapsing polychondritis involving larynx and trachea with bilateral vocal cord palsy which was managed with tracheotomy.

  • Aluminum nitride powder prepared from the hydroxides, AlOOH and Al(OH)3 which were obtained by hydrolysis of Al-isopropoxide, was densified at 1750 and 180$0^{\circ}C$ for 60 min by hot-pressing under the pressure of 25kg/$\textrm{cm}^2$. Theoretical density could be obtained at 175$0^{\circ}C$. Their flexural strengths were 450MPa and 395MPa for the specimens obtained from Al(OH)3 and AlOOH, respectively. There was no remarkable change in flexural strength up to 100$0^{\circ}C$. Fracture toughness values were 3.50MN/m3/2 for Al(OH)3 and 3.11MN/m3/2 for AlOOH. It is assumed that these differences in mechanical properties are due to the abnormal grain growth for the AlN ceramics obtained from AlOOH.

  • When asymmetric thermal-hydraulic conditions occur between cold legs, the core inlet temperature will be nonuniform if the coolant is not mixed perfectly in the lower plenum. These uneven core inlet conditions may induce the change in core power distribution. Thus realistic prediction of thermal mixing is important in such abnormal conditions. In this study, reactor internals, which are scaled down as to conserve the flow area ratio, are set up in the model of KORI Unit 1 with the scaling factor of 1/710 by volume and coolant temperatures are measured beneath the lower core plate. Based on experimental results, the ability of COMMIX-1B code to simulate the coolant mixing phenomena in the lower plenum is estimated. The results show that complete mixing never occurs in any conditions and the mixing pattern is characterized according to the plant type.

  • The porosity is often regarded as a linear function of fluid pressure in porous media and permeability is approximately looked as constants. However, for some scenarios such as unconsolidated sand beds, abnormal high pressured oil formation or large deformation of porous media for pore pressure dropped greatly, the change in porosity is not a linear function of fluid pressure in porous media, and permeability can't keep a constant yet. This paper mainly deals with the relationship between the damage variable and permeability properties of a deforming media, which can be considered as an exploratory attempt in this field.

  • There are three major motives for M&A, financial synergy effect, operating & managerial synergy effect, and tax effect. The purpose of this study is to prove the operating & managerial synergy effect of M&A. To do this, we analyze the market-ripple effect of M&A, focusing on the increase in market power. Specifically we use cross-sectional data from 1985 to 1998 to show whether a market power of mergers is higher than that of a matched non-merging control group. we use time series data to show whether a market power of merger is higher than that of pre-merger. Also we use the event study using market model to show the stock price movement after mergers. The result is that although revenue increase after mergers, profit of the firms does not improve after mergers. Also there is sufficient evidence to say that there is a cumulative abnormal return for the firms after mergers.
