In the North-eastern districts of China, Northern races inherited and developed their own cultural traditions. The housing of northeastern China has been changed under the influence of environment. Some tribes' housings has been developed, keeping their own peculiar style, while others have divested of their ethnic flavor. To understand these aspects of development, this study focused on the housings in Heilongjiang and Nei Monggol. As for the procedure, this study referred to the literature and carried out a field trip at the same time. The housing of northeastern China has undergone the process to fix their residence after the life of migration in common. In this process, northeastern hosing has changed variously and can be grouped into the several types by shape and material. From the point of view about living pattern, some important living features are extracted by the types.

This paper focuses on the development prospects of the UK after Europe, the development situation of the EU and the world's democratic issues were discussed. Professor Zhou Yushu that the old EU pattern may no longer be suitable for contemporary development trends, the need for reform and create a new pattern of mutual benefit and win-win situation. Professor Thomas believes that the impact of Britain's departure from Europe should be viewed from a dialectical perspective, and the benefits and disadvantages of China's economic development plan will be positive for the economic development of Europe as a whole. With the common development of China.

A case of metastatic adenoid cystic carcinoma of the lung, originated from the trachea, was diagnosed by fine needle aspiration. Although the cytologic features of adenoid cystic carcinoma have been well described, it is easy to confuse adenoid cystic carcinoma with more common primary small cell neoplasms of the lung, i.e., small cell carcinoma, well differentiated adenocarcinoma, and carcinoid tumor of the lung. The features distinguishing adenoid cystic carcinoma from these neoplasms include 1) tight, globular, honeycomb pattern of cells, 2) acellualr basement membrane material in the lumen, and 3) cells lacking true nuclear melding and having bland chromatin pattern. The morphologic feature of metastatic adenoid cystic carcinoma in this case was so distinctive as to permit a definite diagnosis by aspiration cytology.

This paper proposes speaker recognition algorithm which includes the pitch parameter for the peak and valley. The time-frequency hybrid method for pitch extraction is valuable in that it can improve resolution in the time domain and accuracy in the frequency domain at the same time. It makes reference pattern using membership function and performs vocal track recognition of common character using fuzzy pattern matching in order to include time variation width for non-linear utterance for proposed method, speaker recognition experiments are carried out using vowels and number sounds.

In this study, we developed rotating machine vibration condition monitoring system based upon Windows NT and DSP Board. Developed system includes signal analysis module, trend monitoring and simple diagnosis using threshold value. Trend analysis and report generation are offered with database management tool which was developed in MS-ACCESS environment. Post-processor, based upon Matlab, is developed for vibration signal analysis and fault detection using statistical pattern recognition scheme based upon Bayes discrimination rule and neural networks. Concerning to Bayes discrimination rule, the developed system contains the linear discrimination rule with common covariance matrices and the quadratic discrimination rule under different covariance matrices. Also the system contains k-nearest neighbor method to directly estimate a posterior probability of each class. The result of case studies with the data acquired from Pyung-tak LNG pump and experimental setup show that the system developed in this research is very effective and useful.

Electronic Speckle Pattern Interferometry(ESPI) is a common method for measuring out-of-plane deformation and in-plane deformation and applied for vibration analysis and strain/stress analysis. However, ESPI is sensitive to environmental disturbance, which provide the limitation of industrial application. On the other hand, Shearography based on shearing interferometer which is insensitive to vibration disturbance can directly measure the first derivative of out-of-plane deformation. In this paper a technique that extract out-of-plane deformation from results of shearography by numerical processing is proposed and measurement results of ESPI and Shearoraphy are compared quantitatively.

We defined life style as something that every members of society have in common. These social and cultural environments build up not only society group or every individual's expectation but also its own life style. In that way, these social and cultural environments leads to particular consumer behavior pattern in this food-service industry. So we regard next generation's trend which consists of rational consumers as important indicator when we make future's plan in foodservice industry. We consider smart map which needs rational and continuous consume pattern as the construction of next generation's main consumer class. Therefore, this study tried to develop of color and image marketing strategies to attract LOHAS and nomadic consumer.

It is very important to select optimal investment alternative. The common method of economic evaluation is to compare of NPV, FW, AE by MARR, or the rate of return for the cash flow of alternatives. This method is undergoing by assumption that cash flow can be always evaluated by MARR, but the cash flow is not always increased or discounted like MARR. So this paper suggests a model on an economic analysis and evaluation regarding to various cash pattern, that is helpful for the person in the field to use easily.

In this paper we： (1) analyze the relationship among public R＆D investment, private R＆D investment, and GDP by employing the Clangor causality test; (2) examine if there is any country-specific pattern in the relationship by testing the cases of Korea, the U.S. and Japan. We found some common results for the above countries as follows： (i) GDP causes Public R＆D, not vice versa; (ii) Private R＆D causes GDP; and (iii) Public R＆D does not cause Private R＆D. For the bivariate model of GDP and total R＆D, the results show the existence of one-way causality running from total R＆D to GDP f3r both U.S. and Japan. We also found bidirectional causal relationship between GDP and total R＆D for Korea, which could be interpreted as a typical pattern for newly industrialized countries.

This paper proposes speaker recognition algorithm which includes both the pitch parameter and the fuzzy inference. This study proposes a pitch detection method PVPF(peak and valley pitch detection fuction) by means of comparing spectra which utilizes the transform characteristics between time and frequency. In this paper, makes reference pattern using membership function and performs vocal tract recognition of common character using fuzzy pattern matching in order to include time variation width for non-linear utterance time.
