The purpose of this study is to understand the characteristic elements of interior space which effects the basic floor plan of traditional houses, in Huizhou, CHINA. The field study for the content analysis of a interior space of traditional houses were conducted from August 16 to 21, 2015, in Xidicun & Hongcun village. The major characteristics of 'tang' interior were as follows; Firstly, all of traditional houses in a skylight that front of 'tang'. Several types of floor plan were fixed by a combination of the space layout and numbers between 'tang' and skylights. Secondly, 'Tang' is from 3,250 to 6,000 mm in width, from 3,800 to 7,800 mm in depth. All skylights are more length than 'tang' in width. So all of spacious 'tang' were very bright without any lighting fixtutes. Thirdly, the patterns of woodcuts were the major settings of interior decorations. All of a window and door, capital has a detail woodcuts that are flowers, animals, plants, peoples, vases, and geometric patterns. In the last analysis, the traditional housing designs in Huizhoui old villages were planned for family that everlasting life, made a functional and rational decision.

This paper focuses on the spatial analysis of traditional houses in Huizhou during the Ming and Qing period in China. It first reviews the spatial characteristics of the houses in Huizhou. Typical configurations, spatial elements and spatial compositions of the houses are briefly examined. It then discusses how those spatial characteristics are applied to the houses. To do so, the review of existing research and literature on the houses was conducted. For a detailed analysis of the houses, a field survey was performed to collect research materials of the houses and to assess the application of the characteristics in the houses. At times, the plans of the houses were redrawn for a further analysis of the spatial compositions of the houses. Attempts have been made to understand the underlying principles of their spatial organization. For example, Jin (2010) examined the spatial organization of unit plans. Boyd (1989), Berliner (2003) and Dan (2005) similarly categorized the organizational typology of its varying designs. Son(1995) further interpreted the spatial relations of the variety of houses in a comprehensive manner. Nevertheless, their analytic methodology falls short of a complete explanation of the spatial expansion and transformation in the houses. Therefore, this paper examines the basic principles behind the spatial expansion and transformation of a variety of traditional houses in Huizhou. In doing so, it strives to make logical sense of design variations in the houses and reveal the theory behind them.

The purpose of this study is to provide the conservation management direction about cultural landscape of the traditional villages in the area of Huizhou through the importance-performance analysis. The results of the survey on the importance - performance of 261 people who had many visits to various cultural landscapes of Huizhou villages such as Hongchun, Sidichun etc. are as follows. It was appeared that the item of 'good air' is the highest level of importance and satisfaction and is best condition. The item of 'historical conservation' is the high level of importance, but the level of satisfaction is low, so continuous improvement is necessary. The item of 'Old garden conservation' has high satisfaction but low importance, so it needs to improve its importance through subsequent improvement. The item of 'Keeping of old cemetary and old tower' has low importance and satisfaction but it is above average, so continuous maintenance is needed. The items of 'Preservation of stone gate' and 'Preservation of famous man's birth house' all have slightly higher satisfaction and lower importance. Both items are highly satisfied with their importance, so they should avoid excessive efforts and maintain the present status. Satisfaction with the item of 'water environment and water quality' was the lowest, and the problem of the present condition is the most serious, and a major improvement is needed. The importance and satisfaction of 'Commercial development of old villages' was the lowest among all items. This item is causing serious problems and should provide an overall improvement way to drastically improve the importance and satisfaction. Concentration is necessary to improve the environment of the whole villages, to protect the ecological plants and animals in old villages, to transfer and improve the culture of old villages, to maintain sustainability of the villages, and to protect old temple and old rock in old villages. As the level of satisfaction with sustainability is the lowest in the part of 'Concentrate here', there is a great concern about sustainability. Therefore, it is necessary to focus on sustainability and concentrate on sustainable development.

The combined ${\bar{X}}-S^2$ chart is a traditional control chart for simultaneously detecting mean and variance. Control limits for the combined ${\bar{X}}-S^2$ chart are determined so that each chart has the same individual false alarm rate while maintaining the required false alarm rate for the combined chart. In this paper, we provide flexibility to allow the two charts to have different individual false alarm rates as well as evaluate the effect of flexibility. The individual false alarm rate of the ${\bar{X}}$ chart is taken to be γ times the individual false alarm rate of the S² chart. To evaluate the effect of selecting the value of γ, we use the out-of-control average run length and relative mean index as the performance measure for the combined ${\bar{X}}-S^2$ chart.

In this thesis, the emphasis is laid especially on the culture & structure of Huizhou Province, China as the prime mover of the specifically-regional Huizhou $X{\bar{i}}n^{\prime}{\bar{a}}n$ medicine. Huizhou was the home town & stronghold of Neo-coufucian masters Cheng-Zhu (Cheng brothers and Zhu-hsi)". The tradition of the region as "The arts province" resulted in the flourishing trend of nurturing prominent Confucian-doctors. The remarkable all round activities of Huizhou Merchants (新安商人 $X{\bar{i}}n^{\prime}{\bar{a}}nsh{\bar{a}}ngr{\acute{e}}n$), as the reigning power merchant at the period were the second mover of the Zeitgeist. Their nation-wide network all over China made it possible to gain valuable inlormation and access to news including the field of medicine in time. Some merchants actually have "abandoned their own jobs to become doctors of medicine". This Confucian-Merchant culture was one of intrinsic characteristics of Huizhou region, inducing "Pragmatic Scholarship". With the enlargement of the population of Confucian-tumed doctors and improvement of the societal status of doctors, the resultant occupational triad of local Confucian govemment officials, local $X{\bar{i}}n^{\prime}{\bar{a}}nsh{\bar{a}}ngr{\acute{e}}n$ merchants, and local doctors was established after the Middle-Ming Dynasty. Ultimately, the two prime movers of the concomitant development of medicine in the Province Huizhou in this study are concluded to be the synergy effects of the Neo-Confucian tradition and economic power of the prevalent Huizhou Merchants ($X{\bar{i}}n^{\prime}{\bar{a}}nsh{\bar{a}}ngr{\acute{e}}n$).

Charts based on geometric distribution are effective to monitor the proportion of nonconforming items in high-quality processes where the in-control proportion nonconforming is low. The implementation of this chart is often based on the assumption that in-control proportion nonconforming is known or accurately estimated. However, accurate parameter estimation is very difficult and may require a larger sample size than that available in practice for high-quality process where the proportion of nonconforming items is very small. An inaccurate estimate of the parameter can result in estimated control limits that cause unreliability in the monitoring process. The maximum likelihood estimator (MLE) is often used to estimate in-control proportion nonconforming. In this paper, we recommend a Bayes estimator for the in-control proportion nonconforming to incorporate practitioner knowledge and avoid estimation issues when no nonconforming items are observed in the Phase I sample. The effects of parameter estimation on the geometric chart and the geometric CUSUM chart are considered when the MLE and the Bayes estimator are used. The results show that chart performance with estimated control limits based on the Bayes estimator is generally better than that based on the MLE.

As interest in social network analysis increases, researchers' interest in detecting changes in social networks is also increasing. Changes in social networks appear as structural changes in the network. Therefore, detecting a change in a social network is detecting a change in the structural characteristics of the network. A local change in a social network is a change that occurs in a part of the network. It usually occurs between close neighbors. The purpose of this paper is to propose a procedure to efficiently detect local changes occurring in the network. In this paper, we divide the network into partitioned networks and monitor each partitioned network to detect local changes more efficiently. By monitoring partitioned networks, we can detect local changes more quickly and obtain information about where the changes are occurring. Simulation studies show that the proposed method is efficient when the network size is small and the amount of change is small. In addition, under a fixed overall false alarm rate, when we partition the network into smaller sizes and monitor smaller partitioned networks, it detects local changes better.
