Background and Purpose: Cisplatin is the most common chemotherapeutic agent for loco-regionally advanced nasopharyngeal carcinoma (NPC); however, toxicity is a limiting factor for some patients. We retrospectively compared the efficacy and toxicity of weekly docetaxel-based and cisplatin-based concurrent chemoradiotherapy in loco-regionally advanced NPC. Methods and Materials: Eighty-four patients with Stage III and IVA-B NPCs, treated between 2007 and 2008, were retrospectively analyzed. Thirty received weekly docetaxel-based concurrent chemotherapy, and 43 were given weekly cisplatin-based concurrent chemotherapy. Radiotherapy was administered using a conventional technique (seven weeks, 2.0 Gy per fraction, total dose 70-74 Gy) with 6-8 Gy boosts for some patients with locally advanced disease. Results: Median follow-up time was 42.3 months (range, 8.6-50.8 months). There were no significant differences in the 3-year loco-regional failure-free survival (85.6% vs. 92.3%; p=0.264), distant failure-free survival (87.0% vs. 92.5%; p=0.171), progression-free survival (85.7% vs. 88.4%; p=0.411) or overall survival (86.5% vs. 92.5%, p=0.298) of patients treated concurrently with docetaxel or cisplatin. Severe toxicity was not common in either group. Conclusions: Weekly docetaxel-based concurrent chemoradiotherapy is potentially effective and has a tolerable toxicity; however, further investigations are required to determine if docetaxel is superior to cisplatin for advanced stage NPC.

目的範疇具有“意向性”、“‘目的-行爲’或‘行爲-目的’的語義關係”、“非現實”等三個根本性的語義特徵。幷且,以這三項語義特徵爲語義基礎可以建立目的範疇。 另外,以是否具有這三項語義特徵爲判斷標準,可以判斷一個句子或格式是否體現目的範疇。本硏究的判斷結果顯示:漢語目的複句、目的緊縮複句、帶有關聯詞語的目的單句、目的連動句以及“V + PO”結構能勾體現目的範疇。 因此,我們可以把關聯詞“爲、爲了、爲著、以、以便、以期、以求、好、借以、用以、來、以免、以防、省得、免得”以及關聯短語“爲(了)……而……、爲(了)……起見、爲的是、是爲了”等看做漢語目的範疇的目的標記。 The purpose category possesses three fundamental semantic features: intentionality, the semantic relationship of “Purpose-Action” or “Action- Purpose”, and irrealis. Moreover, these three semantic features can be used as the semantic foundation to establish the purpose category. In addition, whether a sentence or a construction possesses these three semantic features or not can be regarded as a criteria to tell this sentence or construction reflects the purpose category or not. The findings of this research showed that the purpose conjunctive sentence and the purpose contraction conjunctive sentence, the purpose conjunctive simple sentence which is connected by connectives, the purpose conjunctive serial verb sentence and ‘V + PO’ construction have the function of reflecting the purpose category. Among these members of purpose category, the purpose conjunctive sentence is the most prototypical member, and rest of the members are marginal members. Therefore, we can regard the connective word such as “wei, weile, weizhe, yi, yibian, yiqi, yiqiu, hao, jieyi, yongyi, lai, yimian, yifang, shengde, miande” and the connective phrase such as “wei(le)……er……, wei(le)……qijian, weideshi, shiweile” as the purposive marker of the Chinese purpose category.

Objective: Hypoactivity in the reward system among patients with attention deficit hyperactivity disorder (ADHD) is a well-known phenomenon. Whether the activity in the reward pathway is related to harm avoidance, such as in sensitivity to punishment, is unclear. Evidence regarding the potential difference between ADHD patients and controls in terms of this association is scarce. Methods: Event-related functional magnetic resonance imaging was conducted on subjects performing the Iowa gambling test. Fourteen adults with ADHD and 14 controls were enrolled in the study. Results: Harm avoidance was found to be positively correlated with the activities of the bilateral orbitofrontal cortex and right insula in individuals with ADHD. A group difference was also confirmed. Conclusion: Understanding the roles of harm avoidance and brain activation during risk tasks is important.
Low-Frequency Compensation of Piezoelectric Accelerometers for Motion Control Systems
Lu Yu-Sheng,Lu Chun-Wei 대한전기학회 2021 Journal of Electrical Engineering & Technology Vol.16 No.4
This paper describes how piezoelectric accelerometers can be applied to motion control systems for performance enhancements. Piezoelectric accelerometers are known for their wide frequency ranges to sense dynamic acceleration. However, they are unable to measure static and quasi-static acceleration. Since positional sensors generally exist in motion control systems, this paper presents two acceleration observers that fuse piezoelectric accelerometers and positional sensors and are able to achieve high-quality observation of acceleration, including static and quasi-static components. The proposed observers are applied to a robotic manipulator, and experimental results confi rm feasibility and eff ectiveness of the proposed acceleration observers.

The purpose of this study is to find out the safety crisis of Chinese international students studying in Korea and how to improve safety perception. After COVID-19 as a sudden public event, safety perception and education on public health should be strengthened. Although China is taking many protective measures for the safety of international students, not only the popularity of 'health bags' is high, but also the publicity needs to be improved. The survey results showed that first, it is necessary to establish a mechanism for assessing student safety perception, adjust the focus of education, identify the main factors affecting student safety, and timely and effectively remove the pressure of the epidemic on students. Second, it is necessary to continuously update the safety protection contents for international students. Third, safety education for international students should be thoroughly conducted and attention should be paid to emergency management resources. Fourth, it is required to promote the timeliness and efficiency of information update and to establish a broad and effective information communication channel.
Effect of Impeller Blade Number on Kla in Mechanically Agitated Vessels
Lu Wei Ming,Wu Hong Zhang,Chou Cheng Ying 한국화학공학회 1999 Korean Journal of Chemical Engineering Vol.16 No.5
Effects of impeller blade number on gas dispersion and mass transfer rate were thoroughly investigated for mechanically agitated vessels equipped with 2-, 4-, 6- and 8-straight blades disk turbine impellers. The results show that under the same rotational speed, the impeller with more blades always can disperse gas more effectively, which induces a higher value of $lt;K_La$gt;. However, with the same total power consumption, the 4-blade impeller can obtain a higher $lt;K_La$gt; value than the 6- and 8-blade impellers under a lower gassing rate condition (Q-g$lt;0.5vvm), but if Q_g) exceeds 0.5vvm, the 6-blade impeller will perform better than the 4- and 8- blade impellers. To examine the results obtained from the single impeller systems, the same approach is applied to measure $lt;K_La$gt; values for the triple stage 6-blade impeller system (3×6) and quadruple stage 4-blade impeller system (4×4). From the experimental results, it can be found that the 4×4 system gives higher $lt;K_La$gt; value than the 3×6 system under gas completely dispersed conditions. By correlating $lt;K_La$gt; with n_b, N and V_s, the following correlation can be given as: $lt;K_La$gt; = 0.00119n^(0.62)_bN^(1.56)V^(0.4)_s $lt;K_La$gt; = 0.0297n^(0.1)_b(P_s/V)^(0.34)V^(0.48)_s These two correlations can also be used to evaluate the mass transfer coefficient of each impeller region for the multiple impeller systems and the deviation is always less than 10%.
Particle Size and Loading Effects on Particle-Laden Flow with Mono-sized Droplets
( Wei Hsiang Lai ),( Wei Fu Lu ),( Keh Chin Chang ) 한국액체미립화학회 2010 한국액체미립화학회 학술강연회 논문집 Vol.2010 No.-
Turbulence modulation is an interaction between phases that occurs in multiphase flow, and turbulence intensity traditionally can be represented as an indicator of turbulence modulation. Many researchers paid attention on the subject, but no coincident conclusion can be proposed. A general cognition is that larger particles induced wake to enhance the fluid turbulence intensity and smaller particles suppressed the fluid turbulence intensity since the fluid eddy imparted energy to the smaller particle. Here, the authors orderly changed particle size of dispersed phase and mass loading ratio (LR) to study the change on fluid turbulence intensity. Mono-dispersed droplets with a narrow size distribution were used to load into a homogeneous turbulence to investigate the turbulence modulation. Particle Dynamic Analyzer (PDA) was used to measure the particle (droplets and tracers) dynamic information. The particle concentration effect can be significantly observed. After coupling particle concentration and particle wetting area (πd2), a linear relationship can be obtained and it represents the turbulence modulation dominated the dilute two-phase flow as our expectation.
