Genetic resources of buffalo, cattle, goat, sheep, deer, rabbit, pig, chicken, duck, goose, turkey and swan in Taiwan are conserved in living form or frozen genetic materials. Preserving farm animals in living form must conserve a considerable number of mature individuals with reproductive potential, and continued funding and breeding space are necessary. Based on the afore‐mentioned restraints and consideration of risk diversification, living animals are preserved in Taiwan Livestock Research Institute (TLRI) branches and breeding stock reproduction grounds throughout Taiwan. Genetic materials preserved in frozen form include germ cell (sperm, egg and embryo), tissue, somatic cell, cell line, DNA and gene pool. Those preserved for long term more than 10 years are conserved in liquid nitrogen storage tank at ‒185 to ‒196℃. Animal industry on utilization of farm animal genetics emphasizes the importance of in situ conservation and considers ex situ conservation as an essential complementary activity to in situ. In situ and ex situ utilization are complementary, not mutually exclusive. The exact strategy of germplasm cryobanking will clearly depend on the conservation objectives of TLRI. In situ and ex situ strategies differ in their capacity to achieve the different bio‐utilization objectives. Based on the objectives for bio‐utilization and conservation, the existing national technical capacity and infrastructure for cryoconservation, and amount of capital to invest in developing and maintaining a gene bank for food animal genetic resources (FAnGR), each country should determine for which FAnGR, if any, national cryobanking program should be undertaken. The health and sanitary issues of animals that must be considered when establishing and operating gene banks for animal genetic resources to help prevent the conservation of potentially dangerous pathogens along with the valuable genetic material in the ultra‐low temperature cell repository. Bio‐utilization of material stored in the bio‐bank must eventually be thawed and used to create new animals and therefore, national organization and annotation of the stored material is critical to ensure its proper utilization. Stock animals are the source of semen, embryo and oocytes are usually privately owned. This ownership may or may not change during the gene banking process, but the terms of agreements between bio‐banks and donors must be explicitly defined. Taiwan Animal Germplasm Center now conserves genetic resources of 77 livestock breeds and strains, including 19 native and 38 foreign species as well as 20 new breeds produced by inbreeding in poultry or breed‐crossing with the artificial insemination in livestock. Cryobanking of semen of native animals is for genetic diversity but also for risk management to long‐term global food security. Ex situ conservation program involving in vitro storage of germplasm cryobanking can contribute to ensure that it will be available to allow livestock keepers and animal breeders to confront future changes in animal production and economic environments.

Solar light pipes are effective ways of transmitting sun light into the rooms which are short of daylight and saving electrical lighting consumption in daylight. But solar light pipes can bring heat into the room at the same time. The temperature effect of side lighting solar light pipe and top lighting solar light pipes were tested in this paper. The length of side lighting solar light pipe was 2.6m with the diameter 0.36m. The length of top lighting solar light pipes were 1.3m with the diameter 0.36m.The temperature of air was tested by RH-LOG auto thermoscope. The temperature of the diffuser surface of top lighting solar light pipes was measured by NEC TH5104 Thermal Infrared Imager. The experimental results showed that solar light pipes can not only bring light into otherwise inaccessible or dimly lit places, but also improve the internal environment without generating excessive heat. So solar light pipes are appropriate methods for daylighting.

A novel experimental set-up allowing quantitative determination of the adsorption capacity of gas molecules on a surface under high-vacuum conditions is introduced. Using this system, the toluene adsorption capacities of various carbon nanostructures were determined. We found that for a give surface area, the adsorption capacities of toluene of multi-walled carbon nanotubes and nanodiamonds were higher than that of activated carbon, which is widely used as an adsorbent of volatile organic compounds. The adsorption of toluene was reversible at room temperature.

The genetic diversity of 16 Ganoderma strains was investigated by rDNA-ITS sequencing. Alignment analysis showed that whole length of internal transcribed spacer(ITS1+ITS2) was 500bp and with 139 variation sites (accounting for 23.3％, ITS1 was 66 and ITS2 was 73), 337 conserved sites (accounting for 72.2％), 59 informative sites (accounting for 9.88％), 86 conversion sites (G-A, C-T), 13 transversion site(C-G, T-A). The ratio of transition and transversion in ITS1 was higher than that in ITS2, and the variable sites of ITS2 were more than those of ITS1. The genetic distance among 16 Ganoderma strains is from 0 to 0.121. The genetic distance between G. lipsiense and F-1 was 0, and the genetic distance between Heizhi 02 and Huizhou, Jingda, G. capense was 0.121, 0.117 and 0.120, respectively. The 16 Ganoderma strains were classed into 4 groups. The biggest group is comprised of 12 strains, including Xinzhou, Huizhou, Jingda, 902, F-1, Xianzhi, Meiluo, Taishan, G. applanatum, 05, G. luteomarginatum. The G. atrum and G. sinense were clustered into one group. The G. capense and Zhongzhi was independent group, respectively. These results showed that there were some genetic difference among groups, and there was lower genetic diversity among strains in same groups.

Four Ganoderma lucidum strains, Chizhi 05, Jingda, Huizhou and Xinzhou, were screened out as hybrid parent in order to establish G. lucidum cross breeding system that based on protoplast monokaryogenesis method. Monokaryotic strains of each parental strains were obtained and mating type of each monokaryotic strains were determined. One to three monokaryotic strains that have different mating types were mated, and hybrids were identified by clamp connection observation and antagonist response. The results showed that the number of monokaryon came from Chizhi 05, Jingda, Huizhou and Xinzhou was 9, 14, 40 and 38, respectively. Only one mating type was obtained from Jingda, and two mating types were obtained from the other three strains, Chizhi 05, Huizhou and Xinzhou, respectively. Chi-square test showed that the ratio of two mating types of the three strains was 1:1. Fourteen monokaryotic strains of different mating types from 4 parental strains were select as a cross- breeding materia, and 17 hybrids were obtained, which were identified by clamp connection observation and antagonist response. This study proclaimed that the practicality of the hybridization breeding of G. lucidum by protoplast monokaryogenesis method.

Prostatic calculi are common finding in radiographic examination, however, the true incidence and the clinical significance are not clearly known. We investigated the prevalence of prostatic calculi and the relationship between prostatic calcification and urolithiasis. From a database, 305 consecutive subjects older than 30 years of age who had undergone regular health checks in our hospital from January 2007 to July 2009 were enrolled in this study. Prostatic calculi and urinary stones were confirmed by non-enhanced CT. According to the presence of prostatic calculi, they were divided into two groups and the relationship with urolithiasis was determined using statistical analysis. Among 305 male subjects, prostatic calculi were found in 97 (31.9%), which revealed a linear trend with aging (r=0.928, p=0.023), while asymptomatic upper urinary tract stones were found in 45 subjects (14.9%). A significant difference was observed in mean age (p<0.001), however, no difference was observed in prevalence of diabetes mellitus (DM), hypertension (HT), and body mass index (BMI). In the prostatic calculi group, 24 (24.7%) subjects had previously unknown urolithiasis, while only 21 subjects (10.1%) in the non-prostatic calculi group had urinary stones. The prevalence of urolithiasis was significantly higher in men with prostatic calcification than in those without prostatic calcification (OR=2.92, 95% CI: 1.53-5.58, p=0.001). No significant differences in serum chemistry were observed between the two groups. Among the 45 patients with urolithiasis, no significant differences were observed in the mean stone size according to the presence of prostatic calcification. Our data showed that prostatic calcification was prevalent up to approximately 31.9% and was frequently combined with upper urinary tract stones. These results indicate that evaluation for urolithiasis might be needed in patients with incidentally detected prostatic calcification.

To understand geographic genetic variation of the species and relationships among populations of the bumble bee, Bombus ardens, that is utilized as green house pollinator we expanded our investigation by sequencing somewhat longer mitochondrial DNA (mtDNA) fragment, covering some uninvestigated regions within the species distribution, and analyzing the sequence data in terms of population genetic structure. For the purpose of study, a portion of mitochondrial COI gene, corresponding to "DNA Barcode" region (658 bp) was sequenced from 160 individuals of B. ardens collected over 15 localities in Korea. The sequence data revealed overall relatively low genetic diversity within species, with a maximum sequence divergence of 0.3%. Geographically, one haplotype (BARBA01) was found in all localities surveyed, with the frequency of 91% (145 among 160 individuals), whereas other haplotypes were found in a locality mostly as a single individual, suggesting that haplotype distribution can be summarized as coexistence of widespread, one dominant haplotype and regionally restricted, other haplotypes. Overall, very high rate of per generation female migration (Nm = 4.6 ~ infinite) and very low level of geographic substitution (FST = 0 ~ 0.099) among localities were characteristic. Although some populations were genetically subdivided from the remaining localities in the hierarchical analysis, there was regional polarity on this subdivision. Taken together with gene flow estimates, the nature of genetic divergence of the bumble bee populations is characterized as one that possessing low genetic diversity, high gene flow, and wide spread of one dominant haplotype, consistent with the previous finding. To have further detailed information of this valuable genetic resource, further longer and variable molecular portion is under investigating.

The commercial activated carbons are typically prepared by activation from coconut shell char or coal char containing lots of inorganic impurities. They also have pore structure and pore size distribution depending on nanostructure of precursor materials. In this study, two types of commercial activated carbons were applied for EDLC electrode by removing impurities with acid treatments, and controlling pore size distribution and contents of functional group with heat treatment. The effect of the surface functional groups on electrochemical performance of the activated carbon electrodes was investigated. The initial gravimetric and volumetric capacitance of coconut based activated carbon electrode which was acid treated by HNO3 and then heat treated at 800℃ were 90 F/g and 42 F/cc respectively showing 94% of charge-discharge efficiency. Such a good electrochemical performance can be possibly applied to the medium capacitance of EDLC.

Carbon/silicon composites were synthesized by mixing silicon powders with petroleum pitch and subsequent heat-treatment. The resultant composites were composed of carbon and nano-size crystalline silicon identified by XRD and EDX. FIB images and SEM images were taken respectively to detect the existence of silicon impregnated in carbon and the distribution of silicon on the carbon surface. The obtained carbon/silicon materials were assembled as half cell anodes for lithium ion secondary battery and their electrochemical properties were tested. The pitch/silicon composite (3 : 1 wt. ratio) heat treated at 1000℃ and mixed with 55.5 wt.% of graphite showed relatively good electrochemical properties such as the initial efficiency of 78%, the initial discharge capacity of 605 mAh/g, and the discharge capacity of 500 mAh/g after 20 cycles.
