The percentage of postnatal disabled people and elderly population is rapidly increased by the industrialization, and the improvement of medical technology. The disparity between the city and rural area is in the way to disabled people who need rehabilitation. To solve these problems, Community Based Rehabilitation(CBR) is suggested by WHO. In this study, at first, the CBR model considering the specific characteristics of AnSan City are presented. Secondly, the first, the second, and the third rehabilitation facilities in AnSan City are classified by the CBR model. Thirdly, the estimation of optimum space for physical therapy and occupational therapy at rehabilitation center and public health center are sugested, which are the second level rehabilitation facilities. There are some differences in the distribution of population between new and old area in AnSan City. In other words, the subject population of CBR program in old area is relatively higher than that of new area. So, the CBR program for AnSan City must reflect their regional characteristics. In this study, the therapeutic boundaries of second level rehabilitation facilities is decided through the survey of physical therapists and occupational therapists in general hospitals and nursing homes.

The previous researches on railway sector have focused on the total greenhouse gas(GHG) emission through national approaches. The aim of this study was to calculate GHG emission at a local government level to measure each city's GHG intensity on rail transportation. This study followed 'the guidelines for local government greenhouse gas inventory(issued by Korea Environment Corporation)' including VKT(Vehicle kilometers Travelled) methodology for railway inventory at a metropolitan area. As a result, the gyeongsangbuk-do emitted the highest GHG emissions at a local government level, followed by chungcheongnam-do and chungcheongbuk-do in 2006. Among several cities, Gimcheon-city emitted the highest GHG at basic government level in 2006. In future, the calculation of GHG emissions at local government level can be applied to establish various policies for GHG reduction.

The study aims to provide some plausible explanation for why Vietnamese listed companies only stop at the level of truthful presentation of information related to accounting data through the opinion of independent auditors. The information is only at the level of compliance with the requirements of Circular 155/2015/TT-BTC in form, but in essence is sketchy. What factors affect the level of voluntary disclosure of listed companies in Vietnam? In order to identify the factors affecting voluntary information disclosure on annual reports of listed companies, the study collected data on annual reports of 122 companies listed on the stock market in Ho Chi Minh City in the period 2015-2018 and uses regression analysis methods. The research presents 8 factors affecting the level of voluntary information disclosure including: Firm size, Listed time, Profitability, Solvency, Separation of board of directors and executive director, Board size, Organizational ownership and Foreign ownership. Next, the study conducted descriptive statistical analysis correlation coefficient analysis to examine the correlation and relevance of independent variables measured by the scale ratio, testing multiple linear regression model. The results of the study show that factors listed time, profitability and organizational ownership affecting voluntary information disclosure on annual reports of listed companies in Vietnam.

Common-mode voltage (CMV) causes overvoltage stress to winding insulation and damages AC motors. CMV with high dv/dt causes leakage currents, which create noise problems for equipment installed near the converter. This study proposes a new pulse-width modulation (PWM) strategy for three-level T-type NPC inverters. This strategy substantially eliminates CMV. The principle for selecting suitable triangle carrier signals for the three-level T-type NPC is described. The proposed method can mitigate the peak value of CMV by 50% compared with the phase disposition pulse-width modulation method. Furthermore, the proposed method exhibits better harmonic spectrum and lower root mean square value for the CMV than those of the reduced-CMV method on the basis of the phase opposition disposition PWM scheme with modulation index higher than 0.5. The proposed modulation can easily be implemented using software without any additional hardware modifications. Both simulation and experimental results demonstrate that the proposed carrier phase-shift PWM method has good output waveform performance and reduces CMV.

The purpose of this study is to estimate the economic valuation of rural waste disposal facilities that are one of the rural environmental improvement projects using contingent valuation method(CVM) in Gyongsangbuk-do, Korea. This study surveyed 1,089 households about the WTP(Willing To Pay) of rural waste disposal facilities policy in Gyongsangbuk-do and it was composed with city level and town level. The overall results show that the respondents well accepted the contingent market and would be willing to pay(WTP) a significant amount for the proposed policy program of rural waste disposal facilities. The values estimated for the rural waste disposal facilities are as follows : 1. The maximum WTP was \10,466 in City level and it was \9,104 in town level by per year. 2. The mean WTP was \9,257 in City revel and it was \8,636 in town lever by per year. 3. Total economic benefits for the household amounted to \7,989,046,270 per year. This result can be used to useful base data fir the policy programs of rural waste disposal facilities.

Historically, humans settled in waterside areas that provided abundant resources and water resources. Afterwards, as industrialization progressed, the city's waterfront contributed to the development of the city through water resources, transportation, and maritime trade. In response to changes in industrial structure, over the past few decades, the city's waterfront has transitioned from an industrial and port-oriented function to a public space function. And from the perspective of urban regeneration, research and design on sustainable waterfront space development are being promoted around the world. However, areas near waterfronts are geographically vulnerable to the direct impact of natural disasters caused by climate change, such as sea levelrise and floods. Therefore, it is essential to establish a systematic management plan to ensure the safety of citizens and publicness. Since the 1990s, New York City in the United States has been establishing a city-level waterfront space management plan to ensure the public nature, safety, and equity of waterfront spaces. On the other hand, in South Korea, there is a lack of research on city-level waterfront management plans. Accordingly, this study sought to find implications and policy improvement measures for domestic waterfront space planning by examining the development process and major policies of New York City's waterfront comprehensive plan.

This thesis explores Vitruvius and his impact upon other Renaissance architects who compare a city to a building or a building to a city, who match the city and the building into a human body, and who develop their own works. The objective of this study is to furnish an interpretation of their theory and practice through their literature and designs. In this point of view, this article takes notice of Vitruvius's six concepts coined from venustas and divides them into two parts: i.e. aesthetic quality (ordinatio, dispositio, and distributio) and technical activity (eurythmia, symmetria, and $d{\acute{e}}cor$) each. This thesis indicates that Vitruvius's successive impacts from the concepts bring about concrete design principles through proportional measurements, placing together, and hierarchic values for the former, as well as appropriate use through beautiful look, symmetrical harmony, and appropriate uses for the latter, tracking notions between a city as a house and vice versa, and either the ideas of the house or the city in the synthesis of the human body, which follows the perfect number and module based on the human body. The thesis shows that the representations of architecture and the city take place with the form of a circle and a square that express the religious belief and the cosmos, substantiating the connection between the proportions of the human body and numbers, and ultimately satisfying a concept of centrality, which is slowly extended to the enclosed plaza at the urban level from chambers, atrium, and corridors at the residence level.
