Hung-Wei Chen,Jui-Yu Chou,Chung-Chi Lin,Yu-Der Wen,Wei-Lung Wang 한국응용곤충학회 2016 Journal of Asia-Pacific Entomology Vol.19 No.2

Forcipomyia taiwana, a biting midge, is one of the most annoying blood-sucking pests in Taiwan. The larvae of Forcipomyia species feed primarily on algae, and the adults feed on nectar for nutrition. After mating with male adults, females bite humans and digest blood for the formation and development of their eggs. The bites often cause human itching, swelling, skin lesion and even fatal shock. Harassment from this biting pest has become a serious problem and has influenced the quality of outdoor recreational activities. Thus, it is necessary to understand the ecology of F. taiwana to develop an effective control strategy. This study showed the seasonal variation of yeast compositions in the interior of F. taiwana. Furthermore, we found that Aureobasidium spp. appeared the most during collection times and these yeasts are able to decompose the cellulose, a major component in the cell wall of algae and Oomycete fungi. These fungi infect a broad range of host and have adverse effect on fitness of the biting midges. Thus, Aureobasidium spp. play a crucial role in the defense system of F. taiwana against pathogens. The study provides useful information that could be used in the development of biocontrol strategy in the future.

Fan-Hung Liu,Chang-Shun Hsu,Shun-Tsung Lo,Chiashain Chuang,Lung-I Huang,Tak-Pong Woo,Chi-Te Liang,Y. Fukuyama,Y. Yang,R. E. Elmquist,Pengjie Wang,Xi Lin 한국물리학회 2015 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.66 No.1

We use both the zero-magnetic-field resistivity and the phase coherence time determined by weaklocalization as independent thermometers for Dirac fermions (DF) in multilayer graphene. In thehigh current (I) region, there exists a simple power law TDF / I0.5, where TDF is the effective Diracfermion temperature for epitaxial graphene on SiC. In contrast, TDF / I1 in exfoliated multilayergraphene. We discuss possible reasons for the different power laws observed in these multilayergraphene systems. Our experimental results on DF-phonon scattering may find applications ingraphene-based nanoelectronics.

Kinect based somatosensory exergame is useful to support long-term care as it can motivate chronic rehabilitation patients or elderly with decreasing motor ability to do physical exercise in a pleasant and interesting gaming environment. Dynamic game difficulty adjustment (DDA) technique is implemented in all games to keep players engaged and adhered to the game. For long-term care service, game difficulty has to be manually adjusted as players are not able to or not willing to adjust game settings by themselves. To support manually difficulty adjustment, it is important to conduct player experience study to understand the impact of different game settings or gaming parameters on game difficulty. This paper evaluates the dif-ficulty of a Kinect exergame using objective player experiences derived from Kinect sensor and gameplay based player experience. Specifically, a Kinect exergame for upper arm exercise is developed and deployed to a nursing center at central Taiwan. The challenge (psychological difficulty) and intensity (physiological difficulty) of the game are analyzed using hand movement speed derived from Kinect sensor (objective player experience) and game score (gameplay based experi-ence). The results show that the objective player experience derived from Kinect sensor can help understand the exergame intensity. With cross reference to game performance, subjects who are more engaged in the exergame can be identified.

The results show that the objective player experience derived from Kinect sensor can help understand the exergame intensity. With cross reference to game performance, subjects who are more engaged in the exergame can be identified. Specifically, analysis of the hand movement speed shows that the Kinect exergame considered in this work does not present enough physiological difficulty (intensity) to elderly with level-4 muscle power but does present difficulty to elderly with level-3 muscle power. Subjects with level-3 muscle power who are engaged in the game can be identified from their game scores. As the optimum difficulty level as well as other game settings varies from individual to individual, an important task in exergame design is to dynamically adjust its challenge and intensity so that elderly players can be engaged in and adhered to the game. The results of this paper show that player experiences derived from Kinect sensor and gameplay performance can help game developers better understand, and hence adjust, the game difficulty levels.

Ching-Lung Cheung,Gloria HY.Li,Hang-Long Li,Constance Mak,Kathryn CB. Tan,Annie WC. Kung 대한골다공증학회 2023 Osteoporosis and Sarcopenia Vol.9 No.1

Objectives: To enhance the public awareness and facilitate diagnosis of osteoporosis, we aim to develop a new Chinese Osteoporosis Screening Algorithm (COSA) to identify people at high risk of osteoporosis. Methods: A total of 4747 postmenopausal women and men aged ≥ 50 from the Hong Kong Osteoporosis Study were randomly split into a development (N = 2373) and an internal validation cohort (N = 2374). An external validation cohort comprising 1876 community-dwelling subjects was used to evaluate the positive predictive value (PPV). Results: Among 11 predictors included, age, sex, weight, and history of fracture were significantly associated with osteoporosis after correction for multiple testing. Age- and sex-stratified models were developed due to the presence of significant sex and age interactions. The area under the curve of the COSA in the internal validation cohort was 0.761 (95% CI, 0.711-0.811), 0.822 (95% CI, 0.792-0.851), and 0.946 (95% CI, 0.908-0.984) for women aged < 65, women aged ≥ 65, and men, respectively. The COSA demonstrated improved reclassification performance when compared to Osteoporosis Self-Assessment Tool for Asians. In the external validation cohort, the PPV of COSA was 40.6%, 59.4%, and 19.4% for women aged < 65, women aged ≥ 65, and men, respectively. In addition, COSA > 0 was associated with an increased 10-year risk of hip fracture in women ≥ 65 (OR, 4.65; 95% CI, 2.24-9.65) and men (OR, 11.51; 95% CI, 4.16-31.81). Conclusions: We have developed and validated a new osteoporosis screening algorithm, COSA, specific for Hong Kong Chinese.

( Ming-lung Yu ),( Chao-hung Hung ),( Yi-hsiang Huang ),( Cheng-yuan Peng ),( Chun-yen Lin ),( Pin-nan Cheng ),( Rong-nan Chien ),( Shih-jer Hsu ),( Chen-hua Liu ),( Jee-fu Huang ),( Chung-feng Huang 대한간학회 2018 춘·추계 학술대회 (KASL) Vol.2018 No.1

Aims: The current study aims to elucidate the treatment efficacy (defined as undetectable HCV RNA throughout 12 weeks of post-treatment follow-up, SVR12) and safety DCV/ASV plus ribavirin for 12 weeks in HCV-1b patients without NS5A RAS. Methods: This is a single-arm, open-label phase 2 study. Seventy directly acting antivirals (DAA)-naïve HCV-1b patients without L31/Y93 RAS are planned to receive daclatasvir (60 mg/ day) and asunaprevir (100 mg twice daily) plus weight-based ribavirin (1000-1200 mg/day) for 12 weeks. After treatment they were followed up for 12 weeks. Results: As of 31 Oct 2017, 58 eligible patients are allocated to treatment, with a mean age of 59.3 years and female predominance (67.2%, 39/58). The mean HCV RNA was 5.87+0.77 log10 IU/mL; 23 patients (39.7 %) had significant hepatic fibrosis (>F2). In the modified intention-to-treat analysis, the rate of undetectable HCV at week 1, week 2, week 4, week 8 and endof- treatment was 25 % (14/56), 84.8 % (39/46), 100 % (46/46), 100 % (38/38) and 100 % (27/27), respectively. Undetectable HCV RNA were observed in all of the patients with HCV RNA assessable 4 weeks (SVR4, 18/18) and 12 weeks (SVR12, 12/12) post treatment. None of the 18 patients who completed the 12-week treatment experienced relapse during post-treatment follow-up. The most common adverse event was fatigue (78.3 %), followed by pruritus (65.2 %) and dizziness (52.2 %), of which were considered as ribavirin related. None of the participating subjects withdrew treatment or follow-up throughout the trial peroid. Three serious adverse events were reported which included urosepsis, appendicitis and left ureteral stone. All were unrelated to the investigating drugs. Conclusions: 12 weeks of DCV/ASV plus ribavirin was highly effective and safe in HCV-1b patients without NS5A RAS in the interim analysis. The satisfactory results would be anticipated in the full patient set.

( Ming-lung Yu ),( Ming-lun Yeh ),( Chi-yi Chen ),( Pin-nan Cheng ),( Ming-jong Bair ),( Jyh-jou Chen ),( Ching-chu Lo ),( Chi-ming Tai ),( Ching-yang Tsai ),( Kuo-chih Tseng ),( Chien-hung Chen ),( C 대한간학회 2020 춘·추계 학술대회 (KASL) Vol.2020 No.1

Aims: Insufficient data regarding the treatment strategy for partial response to nucleot(s)ide analogue (NUC) raised the aim of investigating tenofovir alafenamide (TAF) switching for chronic hepatitis B (CHB) patients with advanced fibrosis and partial response to other NUCs. Methods: CHB patients with advanced fibrosis (stage 3 or 4) and under NUC (except TAF) therapy with detectable hepatitis B virus (HBV) DNA for >52 weeks are enrolled to TAF 25 mg/day for 96 weeks. The objectives are viral suppression, alanine aminotransferase (ALT) normalization and safety. Results: From Feb. 2019, 34 patients, including 21 (61.8%) with entecavir, 10 (29.4%) TDF and 3 (8.8%) lamivudine or adefovir, were enrolled (15 [44.1%] male, median 53 years). The fibroscan demonstrated a mean of 10.5 kPa (7 [20.6%] cirrhotic). Sixteen (47.1%) patients were HBV e antigen positive, seven (20.6%) had YMDD mutation. The median HBV DNA level declined from 68.5 IU/mL at enrollment to 27.0 IU/mL at 4^th week, and undetectable at 12^th, 24^th, 36^th week, respectively, after TAF switching, with undetectable HBV DNA in 14/34 (41.2%), 17/33 (51.5%), 15/25 (60.0%), and 9/15 (60.0%) patients and rate of ALT normalization (≤40 U/L) of 85.3%, 85.3%, 84.8%, 92.0%, and 80.0%, respectively, after TAF switching. (figure 1) Two patients experienced transient virological breakthrough and another one developed at the final time follow up. Serum creatinine and eGFR levels were stable after TAF switching (figure 1). Two patients early terminated including one at 12^th week due to personal reason, and another one accidently died at 20^th week due to acute heart attack. Others suffered only mild degrees of adverse events which were considered unrelated to treatment. Conclusions: The preliminary results demonstrated the TAF switching is effective and safe in viral suppression for CHB patients with advanced fibrosis and partial virologic responses to other NUCs.

Construction of the Operating Limits Diagram for a Ship-Based Helicopter Using the Design of Experiments with Computational Intelligence Techniques

Lin Hsin-Hung,Wu Sheng-Ju,Liu Tsung-Lung,Pan Kuan-Cheng 한국항공우주학회 2021 International Journal of Aeronautical and Space Sc Vol.22 No.1

Compared with land-based helicopters, ship-based helicopters are required to land in a more challenging working environment as the airwakes generated by the wind field flowing through the superstructure of the ship changes the wind field structure. This complicates the wind field structure and affects the safety of flight control. The flight safety of the helicopter pilot can be significantly improved with prior understanding of the relevant information in the ship-based helicopter operating limits (SHOL) diagram. In previous studies, the SHOL diagram of ship-based helicopters has been obtained using numerical simulations in conjunction with a flight simulator. However, the flight simulator equipment is expensive and difficult to maintain. This study references the aforementioned studies by initially employing a numerical simulation method to obtain the flow field information of the interaction between the airwakes of the ship’s superstructure and the downwash flow of the helicopter. Then, the flight simulator is replaced by computational intelligence methods involving artificial intelligence. This significantly reduces the research cost for envelope construction. This study integrates design of experiments (DOE) and computational intelligence techniques (soft computing) to establish a recommended range for the SHOL diagram of ship-based helicopters. This study utilizes the DOE and computational intelligence techniques to construct the SHOL diagram of ship-based helicopters, provide suggestions, and serve as a reference for helicopter pilots and engineering designers to improve the safety during flight.
