Jenn-Jhy Tseng,Yi-Huei Chen,Hsiu-Yin Chiang,Ching-Heng Lin 대한부인종양학회 2017 Journal of Gynecologic Oncology Vol.28 No.3

Objective: To evaluate if uterine myoma is associated with breast cancer. Methods: This case-control study used a nationwide database in Taiwan. We identified 24,315 patients with newly diagnosed breast cancer as cases and matched them with 24,281 patients without breast cancer on age, sex, urbanization, income, and initial diagnosis date. Patients with prior mastectomy were excluded. We used logistic regression analysis to assess the association between uterine myoma and breast cancer while adjusting for confounders. We evaluated the impact of surgical removal of uterine myoma on subsequent breast cancer among patients with uterine myoma. Results: We found that 2,892 (11.9%) patients with newly diagnosed breast cancer and 2,541 (10.5%) patients without breast cancer had a history of uterine myoma. The association between breast cancer and uterine myoma was significant (adjusted odds ratio [aOR]=1.14; 95% confidence interval [CI]=1.07–1.21; p<0.001). This association remained in patients who used hormone (aOR=1.20; 95% CI=1.08–1.33; p=0.001) or who did not use hormone (aOR=1.11; 95% CI=1.03–1.19; p=0.005) within 5 years prior to the index date. Surgical removal of uterine myoma was not associated with a decreased risk of breast cancer (aOR=0.99; 95% CI=0.88–1.10; p=0.795). Conclusion: A minor increased risk of breast cancer was found in women with a history of uterine myoma. This association remained in patients with recent hormone use. Removal of uterine myoma was not associated with decreased risk of breast cancer.

Production of Space and Space of Production: High Tech Industrial Parks in Beijing and Shanghai

Jenn-hwan Wang,Tse-kang Leng 고려대학교 민족문화연구원 2011 Cross-Currents Vol.- No.1

The development of high-tech industrial parks (HTIPs) has become a salient phenomenon in China’s economic and urban development. Current studies regarding the development of HTIPs tend to focus either on the active role of the local government or on the consequences of technological innovation that those parks may have brought about. Very few studies have paid attention to the intrinsic relationship between the process of space production in building HTIPs and the effect on urban development. To fill this theoretical gap, this article considers developing HTIPs as a territorial project through which both central and local states seek to promote economic growth by reorganizing their territories so as to facilitate capital accumulation based on building high-tech industrial parks. The authors use Beijing’s Zhongguancun and Shanghai’s Yangpu areas as examples to show the active role played by district governments in promoting and using the symbol of “high tech” to develop industrial estates. In the end, due to the HTIPs’ quick tax-generating potentiality, their construction has given rise to commodity housing and commercial projects which district governments are much more enthusiastic to pursue. The property-led high-tech development projects have paradoxically generated a negative impact on sustainable high-tech development.

Jenn-Jhy Tseng,Chun-Che Huang,Hsiu-Yin Chiang,Yi-Huei Chen,Ching-Heng Lin 대한부인종양학회 2019 Journal of Gynecologic Oncology Vol.30 No.5

Objective Uterine myoma which results in the magnitude of ovarian cancer remains uncertain. This study aimed to assess the association between women with previous uterine myoma and the risk of ovarian cancer. Methods This population-based case-control study was conducted using the Taiwan National Health Insurance Research Database between 2006 and 2010. We identified 4,088 adult women with newly diagnosed ovarian cancer with 16,348 women without ovarian cancer matched for age, urbanization level, income and initial diagnosis date. Logistic regression analyses were used to evaluate the variables associated with ovarian cancer. In addition, the effect of surgical interventions on the risk of ovarian cancer was also evaluated. Results Women with previous uterine myoma were more likely than those who did not to have ovarian cancer (adjusted odds ratio [aOR]=2.26; 95% confidence interval [CI]=2.06−2.49). Patients with uterine myoma who either received (aOR=1.79; 95% CI=1.51−2.13) or did not receive hormone replacement therapy (aOR=2.51; 95% CI=2.24−2.82) experienced a significantly higher risk of ovarian cancer than those without uterine myoma, respectively. However, patients with uterine myoma who underwent either myomectomy (aOR=0.55; 95% CI=0.39−0.77) or hysterectomy (aOR=0.33; 95% CI=0.26−0.42) had a significantly lower risk of ovarian cancer. Conclusion The results revealed that a significantly higher risk of ovarian cancer in women with previous uterine myoma, through an indirect mechanism. Furthermore, a lower risk of ovarian cancer was observed in women who underwent surgical removal of the uterine myoma.

Hegemonic Distortions: The Securitisation of the Insurgency in Thailand’s Deep South

Nicole Jenne,Jun Yan Chang 서강대학교 동아연구소 2019 TRaNS(Trans –Regional and –National Studies of Sou Vol.7 No.2

The conflict between the Thai state and the Malay-Muslim insurgency in the country’s Deep South is one of Southeast Asia’s most persistent internal security challenges. The start of the current period of violence dates back to the early 2000s, and since then, a significant number of studies exploring the renewed escalation have been published. In this study, we argue that existing scholarship has not adequately accounted for the external environment in which political decisions were taken on how to deal with the southern insurgency. We seek to show how the internationally dominant, hegemonic security agenda of socalled non-traditional security (NTS) influenced the Thai government’s approach to the conflict. Building upon the Copenhagen School’s securitisation theory, we show how the insurgency became securitised under the dominant NTS narrative, leading to the adoption of harsh measures and alienating discourses that triggered the escalation of violence that continues today. The specific NTS frameworks that ‘distorted’ the Thai state’s approach of one that had been informed solely by local facts and conditions were those of anti-narcotics and Islamist terrorism, albeit in different ways. Based on the findings from the case study, the article concludes with a reflection on the role of the hegemonic NTS agenda and its implications for Southeast Asian politics and scholarship.

Pulse-Width-Modulation Feedforward Neural Network Design with On-Chip Learning

Bor, Jenn Chyou,Wu, Chung Yu 대한전자공학회 1996 APCCAS:Asia Pacific Conference on Circuits And Sys Vol.1 No.1

In this paper, a CMOS VLSI design of the pulse width modulation (PWM) neural network with on-chip leaning is proposed. The multiplication and summation functions are realized by using the PWM technique and simple mixed-mode circuits with good linearity and large dynamic range. From the measured results, the linearity of synapses versus input pulse widths can be almost kept under ±0.2%. Also the measured results on the simple Chinese word speech classification have successfully verified the function correctness and performance of the designed neural network.

Taiwan Agricultural Ecosystem Plant Investigation Methodology for Evaluating Agricultural Ecosystem Services

Tsai, Jenn-Kuo,Chen, Chi-Ling National Institute of Ecology 2022 Proceedings of NIE Vol.3 No.1

Farming practices that balance environmental friendliness with biodiversity are increasingly valuable. Wild plants on farmlands compete for nutrients with crops and create a crucial microhabitat and resources for animals such as natural enemies. Investigating farmlands and their surrounding plants with limited human and material resources has become an essential aspect of evaluating the agricultural ecosystem services. This study investigated plants in six agricultural long-term ecological research sites in Taiwan from 2017 to 2020 to determine the ideal season for investigation. Cluster analysis was performed to group habitats with similar plant composition, and the species-area curves of the clusters in each season were created. The results indicated that the agricultural ecosystem could be divided into farmlands, banks, orchards, and tea gardens. The habitats were divided into farmland, bank, Chia-Yi orchard, Gu-Keng orchard, and tea garden clusters. Ground plant cover can be investigated all year with at least 18 quadrats. However, if human and material resources are limited, 10 quadrats should be the minimum for farmlands in autumn and for the other microhabitats in spring. The minimum number of quadrats is 10 for banks, 17 for orchards, and 9 for tea gardens.

Mechanical Behavior of Directionally Solidified (Y2O3)ZrO2/Al2O3 Eutectic Fibers

박덕용,Jenn-Ming Yang 한국세라믹학회 2004 한국세라믹학회지 Vol.41 No.1

The microstructural features and mechanical behavior of directionally solidified (Y2O3)ZrO2/Al2O3 eutectic fibers after extended heat treatment in oxidizing environment were investigated. The fiber was grown continuously by an edge-defined film-fed growth (EFG) technique. The microstructure was characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The microstructure of the fiber in the as-fabricated state consists of highly oriented colony and fine lamellar microstructure along the fiber axis. Tensile strength of the (Y2O3)ZrO2/Al2O3 eutectic fiber remained unchanged with heat treatment at temperatures between 1200C and 1500C up to 300hrs. The Weibull’s modulus remained fairly constant after extended thermal exposure. The fracture toughness and crack propagation behavior were investigated. The fracture toughness (K1C) of the (Y2O3)ZrO2/Al2O3 eutectic fiber in the as-fabricated state were measured to be 3.60.5 MPam1/2 by an indentation technique and 2.20.2 MPam1/2 by assuming elliptical flaw of a semi-infinite solid, respectively. The (Y2O3)ZrO2/Al2O3 eutectic fiber showed a radial (Palmqvist) crack type and exhibited an orthotropic crack growth behavior under 100g load.

Incorporation of n-3 Long-chain Polyunsaturated Fatty Acids into Duck Egg Yolks

Chen, Tian-Fwu,Hsu, Jenn-Chung Asian Australasian Association of Animal Productio 2003 Animal Bioscience Vol.16 No.4

The objective of this experiment was to determine the effects of different levels of refined cod liver oil (RCLO) on laying performance, n-3 polyunsaturated fatty acids composition (n-3 PUFAs) and the organoleptic evaluation of duck egg yolks. A total of 180 30 wk old laying Tsaiya ducks, at the beginning of peak production, were allotted into 6 treatments with 3 replicates each. Ducks were fed one of the 6 experimental diets, supplemented with 2% tallow (control) and graded levels of RCLO at 2, 3, 4, 5, and 6% to a corn-soybean diets, respectively, for 6 wks. All of the experimental diets were formulated to be both isocaloric and isonitrogenous. Feed and water were supplied ad libitum throughout the experimental period. The results indicated that the RCLO supplementation levels did not affect (p>0.05) egg production, egg mass, feed intake, feed efficiency or body weight change. Egg weight was the lightest when the ducks received the 6% RCLO diet. The eicosapentaenoic acid, docosahexaenoic acid, and total n-3 PUFAs contents in the yolks increased with increasing RCLO supplementation. The taste and general acceptability of the hard-boiled eggs were not significantly different among the treatments. However, a fishy flavor was much higher when ducks were fed diets supplemented with 5% and 6% RCLO diets.
