Incheon City move onward re-modeling about Jayu Park(public park) in Incheon city. The building restoration must equip all data which are necessary to a restoration and it must be advanced and, currently the project which is advanced is not like that. The place objective which evaluates the restoration possibility of the modern time building where this dissertation is included consequently in project contents it is letting. The evaluation result data is not secured not to be, the restoration is impossible. Also simplicity reappearance of the building where the function disappears without being true feelings characteristic is there is not a possibility of having a construction value. The modern time building restoration which Incheon City it propels consequently it is right to be discontinued.

The related industrial technologies are also being developed in medicine, education, the military, transportation, process management, security management and information technology industries due to a rapid progress in telecommunications technology. The supervisory remote control system is based upon telecommunications technology. The supervisory remote control systems are used in various ways such as city gas, water supply and drainage, environment, power, communication and device control fields. The supervisory remort control system became a solution with complex systems and important technologies in electricity, city gas filed that require safety management skills. The supervisory remote control system as a special technology has a lot of practical applications. In this paper, Let me examine the present status of remort control system applications and present development plans and alternatives in city-gas industrial technology.

According to opening the domestic existing lines and High-Speed Lines(HSL) depending on each section and phase-in, there were constructed in railway over state-of-the-art radio communication networks. Therefore, there have been 3 wireless communication networks in domestic railways in accordance with running sections as like VHF, TRS-ASTRO and TRS-TETRA. For instance, the VHF networks were constructed in exsiting lines and TRS-ASTRO were Kyungbu HSL phase-1 except Seoul-Kwangmyung section, downtown in Daejeon City and that of Daegu City. And it was constructed in DongDaegu-Busan section of Kyungbu HSL phase-2, Osong-Kwangju section of Honam HSL phase-1 and would be done in Kwangju-Mokpo of Hanam HSL phase-2 and Soosu-Pyungtaek of Metropolitan Area Line by TRS-TETRA. In this paper, we described some important problems of radio communication management and investigated current state of radio communication for railways. Moreover, we presented the necessity of integrated radio networks for domestic railways.

The landscape plannings were composed of the fundamental provisions which are important factors for the city and local plannings in Germany. The State Government run institute like LOLF in NRW have been established to solve the serious ecological problems. The institute have completed the basic system covering various ecological problems, such as environmental affection analysis and ecological risk, to contribute the application of the various land-using plants. The ecological landscape plannings are regarded as major fundamental plans of environmental preservation for the plannings development. The problems about the local landscape plannings needed to be preserved ecologically are introduced into the Federal Nature Preservation Law and State Congress Law in order to carry out the environmental protection policy effectively. The local landscape plannings are divided into two-step models by the special classification system for the planning. One is build-up of an independent design separated from city plans functionally, and the other is a systematic regulation for cooperation between the local plans and ecological conservation functions. The local plannings including lands to be preserved as the Nature Preservatin Zone is classified a rest area total sectioned plains.

Forecasting prices in electricity markets is critical for consumers and producers in planning their operations and managing their price risk. We utilize the generalized autoregressive conditionally heteroskedastic (GARCH) method to forecast the electricity prices in two regions of New York： New York City and Central New York State. We contrast the one-day forecasts of the GARCH against techniques such as dynamic regression, transfer function models, and exponential smoothing. We also examine the effect on our forecasting of omitting some of the extreme values in the electricity prices. We show that accounting for the extreme values and the heteroskedactic variance in the electricity price time-series can significantly improve the accuracy of the forecasting. Additionally, we document the higher volatility in New York City electricity prices. Differences in volatility between regions are important in the pricing of electricity options and for analyzing market performance.

Purpose: This study was conducted in order to investigate factors related to depression of elderly women in a Metropolitan city. Methods: Subjects included 118 elderly women older than 65 years of age. Structured questionnaires were used for data collection, and descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and hierarchical regression analysis were performed for data analysis. Results: A significant difference in depression was observed according to number of chronic diseases(F=4.963, p=.001). Significant factors influencing depression included number of chronic diseases (${\beta}$=.265, p<.01), cognitive function (${\beta}$=.290, p<.01), quality of sleep(${\beta}$=.212, p<.01), and nutritional state (${\beta}$=.161, p<.05). These factors explained 54.2% of the variance. Conclusion: Findings of this study suggest the need for development of nursing strategies to decrease the incidence of depression in elderly women.

In this paper, we proposed MLP(MultiLayer Perceptron) based HMM's(Hidden Markov Models) with bounded state duration for isolated word recognition. The minimum and maximum state duration for each state of a HMM are estimated during the training phase and used as parameters of constraining state transition in a recognition phase. The procedure for estimating these parameters and the recognition algorithm using the proposed HMM's are also described. Speaker independent isolated word recognition experiments using a vocabulary of 10 city names and 11 digits indicate that recognition rate can be improved by adjusting the minimum state durations.

An analysis of the throughput and stability region of random access systems is currently of interest in research and industry. This study evaluated the performance of a multiuser random access channel with a retransmission gain. The channel was composed of a media access control (MAC) determined by the transmission probabilities and a multiuser communication channel characterized by the packet reception probabilities as functions of the number of packet transmissions and the collision status. The analysis began with an illustrative two-user channel, and was extended to a general multiuser channel. For the two-user channel, a sufficient condition was derived, under which the maximum throughput was achieved with a control-free MAC. For the channel with retransmission gain, the maximum steady throughput was obtained in a closed form. The condition under which the random access channel can acquire retransmission gain was also obtained. The stability region of the general random access channel was derived. These results include those of the well-known orthogonal channel, collision channel and slotted Aloha channel with packet reception as a special instance. The analytical and numerical results showed that exploiting the retransmission gain can increase the throughput significantly and expand the stability region of the random access channel. The analytical results predicted the performance in the simulations quite well.
