PurposeIn contrast to the core part of the clinical interviewing and physical examination (PE) skills course, corresponding to the basic, head-to-toe, and thoracic systems, learners need structured feedback in the cluster part of the course, which includes the gastrointestinal, neuromuscular, and musculoskeletal systems. This study evaluated the effects of using Dreyfus scale-based feedback, which has elements of continuous professional development, instead of Likert scale-based feedback in the cluster part of training in Taiwan. MethodsInstructors and final-year medical students in the 2015-2016 classes of National Yang-Ming University, Taiwan comprised the regular cohort, whereas those in the 2017-2018 classes formed the intervention cohort. In the intervention cohort, Dreyfus scale-based feedback, rather than Likert scale-based feedback, was used in the cluster part of the course. ResultsIn the cluster part of the course in the regular cohort, pre-trained standardized patients rated the class climate as poor, and students expressed low satisfaction with the instructors and course and low self-assessed readiness. In comparison with the regular cohort, improved end-of-course group objective structured clinical examination scores after the cluster part were noted in the intervention cohort. In other words, the implementation of Dreyfus scale-based feedback in the intervention cohort for the cluster part improved the deficit in this section of the course. ConclusionThe implementation of Dreyfus scale-based feedback helped instructors to create a good class climate in the cluster part of the clinical interviewing and PE skills course. Simultaneously, this new intervention achieved the goal of promoting medical students’ readiness for interviewing, PE, and self-directed learning.

Purification of durene from the mixture of durene and isodurene by stripping crystallization

Lie-Ding Shiau 한국화학공학회 2021 Korean Journal of Chemical Engineering Vol.38 No.12

Stripping crystallization (SC) is introduced in this work to purify durene from the mixture consisting of isodurene and durene. SC is a new technology which combines melt crystallization and vaporization via a series of three-phase transformations at low pressures during the cooling process. The three-phase transformation conditions for a liquid mixture determined by the thermodynamic calculations were adopted to direct the batch SC experiments. A model based on the mass and energy balances was proposed to determine the variation of the amount of remaining liquid, crystallized durene product and produced vapor during SC. The experimental yield and purity of the final durene product obtained from the experiments were compared with those predicted by the model.

Separation of the catechol/4-methoxyphenol mixture by stripping crystallization

Lie-Ding Shiau,Shu-Li Zeng 한국공업화학회 2012 Journal of Industrial and Engineering Chemistry Vol.18 No.3

This work presents a novel separation scheme, stripping crystallization (SC), to separate the catechol/4-methoxyphenol mixture. While operated at a triple-point condition, in which the liquid mixture is vaporized and crystallized simultaneously due to the three-phase equilibrium, SC combines distillation and crystallization to produce pure crystals. Experimental results demonstrate the feasibility of applying SC to purify catechol in the catechol/4-methoxyphenol mixture. However, purifying 4-methoxyphenol by SC in the catechol/4-methoxyphenol mixture is rather difficult.

Wavelet-Based Detection of Time-Frequency Changes for Monthly Rainfall and SPI Series in Taiwan

Jenq-Tzong Shiau,Yun-Feng Chiu 한국기상학회 2019 Asia-Pacific Journal of Atmospheric Sciences Vol.55 No.4

This study aims to assess time-frequency changes and trends of both monthly rainfall and SPI (standardized precipitation index) series in Taiwan using wavelet transform and Mann-Kendall test. The monthly data at Taipei, Sunmoon Lake, Kaohsiung, and Dawu stations with recorded length of 118, 73, 83, and 75 years, respectively, are used. The results of MK test reveal that insignificant positive monotonic trends for both rainfall and SPI series at west-side Taiwan (Taipei, Sunmoon Lake, and Kaohsiung stations) are observed, while both series have significant negative trends at Dawu station located at southeastern Taiwan.Wavelet analyses on the rainfall and SPI series indicate similar variation of wavelet power spectrum over time except the noticeable one-year periodicity in rainfall series and less power spectrum in SPI series. It is worth to note that the sub-decadal 36- and 96-month periodicities are common, but insignificant, at four stations for both series, although different data lengths are used. Combined with MK-test and wavelet-analysis results reveal that slightly less severe and less frequent droughts occur at Taipei and Sunmoon Lake stations, while drought frequencies probably remain unchanged at Kaohsiung and Dawu stations with slightly less severe and more severe droughts respectively occur at these two stations.

Development of primary cell cultures from the adult xylem-feeding leafhopper, Kolla paulula, as a tool for studying Wolbachia biology

Rong-Jen Shiau,Yu-Der Wen,Hsien-Tzung Shih,Shin-Yi Chen,Chiou-Chu Su,Wei-Huang Tsai 한국응용곤충학회 2011 Journal of Asia-Pacific Entomology Vol.14 No.4

Xylophagous leafhoppers are vectors of xylem-limited plant pathogens such as citrus variegated chlorosis (CVC) and Pierce's disease, which cause Xylella diseases. Currently, no cure for Xylella diseases exists. The objective of endosymbiont control using Wolbachia pipientis is to reduce the populations of insect vectors,potentially preventing the expansion of Xylella diseases. The purpose of this study was to establish primary cell cultures from adult xylem-feeding leafhoppers to study Wolbachia biology. Cells from adult male and female Kolla paulula (Walker) (Hemiptera: Membracoidea: Cicadellinae) were successfully cultured in Dulbecco's Modified Eagle Medium containing 20% fetal bovine serum and were maintained for more than 6 months. Cells of both male and female adults are round and semi-attached. The doubling times for male and female K. paulula cells are approximately 8 and 10 days, respectively. The presence of Wolbachia in K. paulula cell cultures was detected by polymerase chain reaction (PCR) amplification of Wolbachia surface protein (wsp) gene. The cell cultures developed in this study may be useful in studying interactions between Wolbachia and its hosts of different genders.

Improvements of GC and HPLC Analyses in Solvent (Acetone-Butanol-Ethanol) Fermentation by Clostridium saccharobutylicum Using a Mixture of Starch and Glycerol as Carbon Source

Tsuey, Liew Shiau,Ariff, Arbakariya Bin,Mohamad, Rosfarizan,Rahim, Raha Abdul The Korean Society for Biotechnology and Bioengine 2006 Biotechnology and Bioprocess Engineering Vol.11 No.4

A study on the feasibility of using improved computer-controlled HPLC and GC systems was carried out to shorten the time needed for measuring levels of the substrates (glucose, maltose, and glycerol) and products (acetone, butanol ethanol, acetic acid, and butyric acid) produced by Clostridium saccharobutylicum DSM 13864 during direct fermentation of sago starch to solvent. The use of HPLC system with a single injection to analyse the composition of culture broth (substrates and products) during solvent fermentation was achieved by raising the column temperature to $80^{\circ}C$. Although good separation of the components in the mixture was achieved, a slight overlap was observed in the peaks for butyric acid and acetone. The shape of the peak obtained and the analysis time of 26.66 min were satisfactory at a fixed flow rate of 0.8mL/min. An improved GC system was developed, that was able to measure the products of solvent fermentation (acetone, butanol, ethanol, acetic acid, and butyric acid) within 19.28 min. Excellent resolution for each peak was achieved by adjusting the oven temperature to $65^{\circ}C$.

Nonstationary Distributional Changes of Annual Rainfall Indices in Taiwan

Jenq-Tzong Shiau,Pei-Syun Wu 한국기상학회 2021 Asia-Pacific Journal of Atmospheric Sciences Vol.57 No.3

The purpose of this study is to detect alterations of annual rainfall regime in terms of distributional changes of rainfall indices in Taiwan. A total of nine rainfall indices at eight stations with at least 72-year daily records are used to characterize annual rainfall regime. The generalized additive models for location, scale, and shape (GAMLSS) is adopted for dynamically detecting evolution of probability distributions of these indices. The results indicate that alterations of annual rainfall regime are spatial diverse and no prevalent distributional changes are observed. Approximate half indices (35/72) exhibit stationarity and WRR (wetseason rainfall ratio) is the least-affected index since only two stations (Sunmoon Lake and Chengkung) revealing nonstationarity. On the contrary, PRCPTOT (annual total rainfall), SDII (simple daily intensity index), and ADD (annual dry days) are high-affected indices due to 75% of stations exhibiting nonstationarity. Highly affected stations include Taipei, Hengchun, and Dawu because two (WRR and CRX (maximum consecutive rainfall)), one (WRR), and one (WRR) indices classified as stationarity, respectively. Taichung and Sunmoon Lake are least-affected stations since 7 out of 9 indices revealing stationarity. These facts indicate that annual rainfall regime of central-west Taiwan is less affected, and north and southeastern regions are change-prone regions.
