This study presents the first analysis system and fast-access cloud database for shrinkage and creep of concrete in the world, named "shrinkage and creep database in Taiwan", SCDT. SCDT not only has the most comprehensive experimental data, including NU, JSCE, Europe, and TW databases, but provides a design tool for researchers and engineers. It can further facilitate the development of prediction models for localized concrete. Users can obtain the shrinkage and creep curves based on their selected prediction models in SCDT. Comparisons of the predicted results of selected models and test results in the chosen database can be generated in seconds. One example of the development of basic creep prediction model in Taiwan based on model B4 by using SCDT to reflect concrete characteristics in Taiwan is also presented in this study. Users anywhere in the world can easily access SCDT to browse and upload data, receive predictive results, or develop predictive models.

주희(朱熹)는 정이가 제기한 '리일분수(理一分殊)'의 명제를 계승하여 십 수년의 노력을 기울인 후에 최종적으로 "서명해(西銘解)"를 지었다. 이로부터 '리일분수(理一分殊)'의 사상은 "서명(西銘)"을 해석하는 모델이 되었으며, "서명(西銘)"의 기조(基調)를 확정하는 역할을 하게 되었다. '리일분수론(理一分殊論)'은 처음에는 "서명(西銘)"의 윤리학적 의의를 표현하는 명제였다. 그런데 주희(朱熹)의 일생을 통해 볼 때 '리일분수론(理一分殊論)'은 단순히 "서명(西銘)"의 윤리학적 의의에 국한되지 않고, 보편적인 철학적 의의를 포함하며, 사물의 일반과 특수의 관계를 표현하는 데에도 사용되었다. 전자는 협의의 '리일분수론(理一分殊論)'이고, 후자는 광의의 '리일분수론(理一分殊論)'이라고 할 수 있다. 이 글에서는 광의적인 리일분수론(理一分殊論)에 대해서는 논하지 않고, 주희(朱熹)가 확립한 "서명(西銘)"을 해석하는 모델로서의 협의의 리일분수론(理一分殊論)을 연구 대상으로 삼고자 한다. 학술계의 선행연구 중에서 어떤 학자들은 '리일분수(理一分殊)'의 명제가 "서명(西銘)"의 의미와 일치한다고 생각하지만, 다른 어떤 학자들은 일치하지 않는다고 주장한다. 이러한 두 종류의 사고방식은 확연히 상반되는 입장이다. 이 글에서는 리일분수(理一分殊) 사상에 의한 주희(朱熹)의 "서명(西銘)" 해석이 어떤 부분에서는 "서명(西銘)" 본래의 뜻과 일치하기도 하지만, 또다른 어떤 부분에서는 서로 부합하지 않는 곳도 있다는 입장을 견지한다. 달리 말하면, 주희(朱熹)가 리일분수론(理一分殊論)으로 "서명(西銘)"을 해석할 때, '공헌(貢獻)'과 '제한('制限)'의 의미를 동시에 지닌다는 것이다. 즉, 리일분수론(理一分殊論)에 의한 주희(朱熹)의 "서명(西銘)" 해석은 그 의미를 확장시킨 부분도 있지만, "서명(西銘)" 본래의 목표로부터 멀어진 부분도 있다는 의미이다.

The purpose of this study is to investigate the anti-aging and anti-oxidative effects of oral administration with SYG (SipYiMiGwanJungTang) decoction in early aged rats. The results were as follows : 1. At the 52 week of the SYG group, the body weight gain was decreased. 2. At the 52 week of the SYG group, the activity of the SOD in the liver was significantly increased than the 10, 22 and 40 week. 3. At the 52 week of the SYG group, the level of the glutathione in the liver was significantly increased than the normal group. 4. At the 68 week of the SYG group, the activity of the catalase in the liver was significantly increased than the normal and control group. 5. At the 52 week of the normal group, the level of the NO in the liver was significantly increased than the 22 and 40 weeks. But, the level of the NO of the SYG group was not changed by the aging. 6. At the 52 and 68 weeks of the SYG group, the level of the MDA in the liver was significantly decreased than the normal and control groups. These results suggest that oral administration of SYG (SipYiMiGwanJungTang) decoction has anti-oxidative and anti-aging effects in early aged rats.

In this study an output-only system identification technique for civil structures under ambient vibrations is carried out, mainly focused on using the Stochastic Subspace Identification (SSI) based algorithms. A newly developed signal processing technique, called Singular Spectrum Analysis (SSA), capable to smooth a noisy signal, is adopted for preprocessing the measurement data. An SSA-based SSI algorithm with the aim of finding accurate and true modal parameters is developed through stabilization diagram which is constructed by plotting the identified system poles with increasing the size of data matrix. First, comparative study between different approaches, with and without using SSA to pre-process the data, on determining the model order and selecting the true system poles is examined in this study through numerical simulation. Finally, application of the proposed system identification task to the real large scale structure: Canton Tower, a benchmark problem for structural health monitoring of high-rise slender structures, using SSA-based SSI algorithm is carried out to extract the dynamic characteristics of the tower from output-only measurements.

Indium-nitrogen co-doped zinc oxide thin films (INZO) were prepared on glass substrates in the atmosphere by ultrasonic spray pyrolysis. The aqueous solution of zinc acetate, ammonium acetate and different indium sources: indium (III) chloride and indium (III) nitrate were used as the precursors. After film deposition, different anneal temperature treatment as 350, 450, $550^{\circ}C$ were applied. Electrical properties as concentration and mobility were characterized by Hall measurement. The surface morphology and crystalline quality were characterized by SEM and XRD. With the activation energy analysis for both films, the concentration variation of the films at different heat treatment temperature was realized. Donors correspond to zinc related states dominate the conduction mechanism for these INZO films after $550^{\circ}C$ high temperature heat treatment process.

Preimplantation genetic diagnosis (PGD) is gradually widely used in prevention of gene diseases and chromosomal abnormalities. Much improvement has been achieved in biopsy technique and molecular diagnosis. Blastocyst biopsy can increase diagnostic accuracy and reduce allele dropout. It is cost-effective and currently plays an important role. Whole genome amplification permits subsequent individual detection of multiple gene loci and screening all 23 pairs of chromosomes. For PGD of chromosomal translocation, fluorescence $in-situ$ hybridization (FISH) is traditionally used, but with technical difficulty. Array comparative genomic hybridization (CGH) can detect translocation and 23 pairs of chromosomes that may replace FISH. Single nucleotide polymorphisms array with haplotyping can further distinguish between normal chromosomes and balanced translocation. PGD may shorten time to conceive and reduce miscarriage for patients with chromosomal translocation. PGD has a potential value for mitochondrial diseases. Preimplantation genetic haplotyping has been applied for unknown mutation sites of single gene disease. Preimplantation genetic screening (PGS) using limited FISH probes in the cleavage-stage embryo did not increase live birth rates for patients with advanced maternal age, unexplained recurrent abortions, and repeated implantation failure. Polar body and blastocyst biopsy may circumvent the problem of mosaicism. PGS using blastocyst biopsy and array CGH is encouraging and merit further studies. Cryopreservation of biopsied blastocysts instead of fresh transfer permits sufficient time for transportation and genetic analysis. Cryopreservation of embryos may avoid ovarian hyperstimulation syndrome and possible suboptimal endometrium.

In this paper, a visualization digital forensics tool, called JumpList Analyzer, is implemented. The tool can analyze the complicated Jump Lists files, and then the results are demonstrated by visualization. To compare the proposed tool with the other Jump Lists tools, the proposed tool is the only one can display the analyzed results by visualization. The visualization will help the investigators more easily to find the evidence than the other tools showing the analyzed results by texts only. In the experiment, the proposed JumpList Analyzer is demonstrated its convenience at identifying artifacts for doing digital forensics in a financial fraud case. In addition, the proposed tool can also be used to reveal the computer user's behavior or background.
