      • 鍛辭成章: 「閱讀促進學習」教學法中筆記摘錄與共同建構在香港非華 語初中課堂的實踐與成效

        Loh,Ka,Yee,Elizabeth,Shum,Shui,Kee,Mark,Lai,Kwok,Chang,Leung,Tit,Hei,Nixon,Lam,Ka,Chun 단국대학교 한문교육연구소 2019 International Han-character Education Research Vol.1 No.1

        최근 홍콩에서 중국어를 모국어로 사용하지 않는 학생들을 합격시킨 주류 중등학교들이 급증하고 있다.(2016, 입법회). 이 학교는 이러한 학생의 학습 차이를 고려하여 다양한 대처를 필요로 하고 있다. 다양한 방식을 채택하여 학생들이 중국어 학습을 잘 마칠 수 있게 지원하여, 그들의 진학이 구직난을 해소하고 사회 상류로의 진출 기회가 될 수 있도록 해야 한다.(Leung et al 2017; Loh & Tam, 2016). (중국은) 중국어를 사용하지 않는 학생들에게 적합한 중국어 교육법을 제공하 는 것이 필요하다고 판단하고 있으며, 이는 해결해야 할 급선무 문제가 되었다.(shum, 2015). 본 연구는 이러한 홍콩의 상황에 집중하였다. 「阅读促进学习」(Rose&Martin, 2012) 교수법은 비 중국어 사용자 학생들의 비율이 비교적 높은 중등학교 한 곳을 선정하고, 제2외국어 교육 과정을 중국어로 하는 대외한어교육현장에서 제 2외국어 학습 기관(홍콩교육국, 2014) 및 국제 일반 중등학교 교육 증서(IGCSE)의 교육과정 개요를 참조하여, 본 교육과정(커리큘럼)을 수정 하였다. 협업과 회의를 통해 공동으로 수업을 준비하고 교육현장을 관찰하는데, 교사와 학생들이 모인 소그룹 인터뷰, 필기 및 수업 원본 분석 등의 방법을 진행하였다. 이를 통해 본 교수법이 학생들에게 설명문 종류의 글을 읽고 쓰는 능력을 향상시키고 학습 동기를 높일 수 있는지의 여부를 검토하였다. 교사는 학생들이 본문을 자세하게 읽도록 한 후, 그룹 협업을 통해 그 문장에 서 핵심 키워드를 발췌하여 노트에 기록하도록 학생들을 지도하는 방법(Note Making)을 시행하고, 이어서 학생들은 상호 간의 교류와 협력에 의해 문장 속에 등장한 핵심 단어들과 구 형식, 문장 형식을 활용하여, 협업을 통해 새로운 글을 창작하고, 마지막으로 학생들이 각자 개별적으로 작문을 수행하게 하였다. 본 연구를 통해, 상술한 단계가 학생들이 문장 형식에 따른 다양한 언어 능력의 차이를 이해하도록 돕는데 효과적이며, 서로 다른 글쓰기 활동에 활용할 수 있음을 발견했다. 원전 분석 및 소그룹 인터뷰 또한 위 교수법이 학생들의 중국어 학습 동기를 향상시키는 데 효과가 있음과 학생들의 학습에 대한 믿음이 증가한 것을 보여주었다. 본 연구는 阅读促进学习 교수법이 학생들의 읽기와 쓰기 능력을 개선하고, 각 교육 절차의 실천적 성과들이 모두 시사성이 있음을 검증하였다는데 그 의의가 있다. In Hong Kong, the number of secondary schools admitting Non-Chinese Speaking (NCS) students has increased tremendously in recent years (LegCo, 2016), in which most of them are mainstream schools. To cater the learning differences of NCS students, various supportin g programs have been employed to help NCS students to improve their Chinese so as to ease their difficulties in applying for universities and finding jobs (Loh & Tam, 2016), and hence enhancing upward social mobility (Leung et al, 2017). Thus developing suitable Chinese as a Second Language (CSL) pedagogies has caught much scholarly attention with pressing needs. Under such backdrop, the paper discusses the use of “Reading to Learn (R2L)” Pedagogy (Rose & Martin, 2012) to support the junior secondary CSL teaching and learning in a secondary school with high NCS density. The research team developed school-based teachin g and learning materials based on Chinese Language Curriculum Second Language Adapted Learning Framework (EDB, 2014) and International General Certificate of Secondary Educat ion (IGCSE) syllabus. Based on collaborative lesson preparation, class observation, teachers and students focus groups, close examination of students'work, the study aims at finding the effectiveness of R2L in enhancing students' reading and writing abilities of explanatory essays, as well as their motivation. Through Detailed Reading, Note-making, Joint Rewriting and Joint Construction, with extensive scaffolding and teacher-student interaction, students are able to understand the register variables and transfer to individual writing of explanatory essays. Discourse analysis and focus group interviews also show that R2L can enhance the motivation of students and their confidence in learning Chinese. The study explores the potential of applying R2L pedagogy to enhance the reading and writing of explanatory essay s, as well as discerning the praxis and effectiveness of various teaching stages.

        Vibration-based identification of rotating blades using Rodrigues' rotation formula from a 3-D measurement

        Loh,,Chin-Hsiung,Huang,,Yu-Ting,Hsiung,,Wan-Ying,Yang,,Yuan-Sen,Loh,,Kenneth,J. Techno-Press 2015 Wind and Structures, An International Journal (WAS Vol.21 No.6

        In this study, the geometrical setup of a turbine blade is tracked. A research-scale rotating turbine blade system is setup with a single 3-axes accelerometer mounted on one of the blades. The turbine system is rotated by a controlled motor. The tilt and rolling angles of the rotating blade under operating conditions are determined from the response measurement of the single accelerometer. Data acquisition is achieved using a prototype wireless sensing system. First, the Rodrigues' rotation formula and an optimization algorithm are used to track the blade rolling angle and pitching angles of the turbine blade system. In addition, the blade flapwise natural frequency is identified by removing the rotation-related response induced by gravity and centrifuge force. To verify the result of calculations, a covariance-driven stochastic subspace identification method (SSI-COV) is applied to the vibration measurements of the blades to determine the system natural frequencies. It is thus proven that by using a single sensor and through a series of coordinate transformations and the Rodrigues' rotation formula, the geometrical setup of the blade can be tracked and the blade flapwise vibration frequency can be determined successfully.

        Factors Associated with Resolution of Hypertension after Adrenalectomy in Patients with Primary Aldosteronism

        Wann,Jia,Loh,Dawn,Shao,Ting,Lim,Lih,Ming,Loh,Peng,Chin,Kek 대한내분비학회 2018 Endocrinology and metabolism Vol.33 No.3

        Background: The aim of this study was to investigate the factors associated with resolution of hypertension after adrenalectomy inpatients with primary aldosteronism. A secondary aim was to describe our use of the contralateral ratio in adrenal venous sampling(AVS) in the setting of suboptimal successful cannulation rates. Methods: A retrospective review of patients who underwent AVS followed by unilateral adrenalectomy for primary aldosteronismwas performed. Results: Complete resolution of hypertension and hypokalemia was seen in 17 of 40 patients (42.5%), while a clinical improvementin hypertension was seen in 38 of 40 (95%). Shorter duration of hypertension, mean aldosteronoma resolution score (ARS), and ahigh ARS of 3 to 5 were associated with resolution of hypertension after adrenalectomy (P=0.02, P=0.02, and P=0.004, respectively). Of the individual components of ARS, only a duration of hypertension of ≤6 years was associated with resolution of hypertensionafter adrenalectomy (P=0.03). Conclusion: A shorter duration of hypertension was significantly associated with resolution of hypertension after adrenalectomy inpatients with primary aldosteronism.

      • A distributed piezo-polymer scour net for bridge scour hole topography monitoring

        Loh,,Kenneth,J.,Tom,,Caroline,Benassini,,Joseph,L.,Bombardelli,,Fabian,A. Techno-Press 2014 Structural monitoring and maintenance Vol.1 No.2

        Scour is one of the leading causes of overwater bridge failures worldwide. While monitoring systems have already been implemented or are still being developed, they suffer from limitations such as high costs, inaccuracies, and low reliability, among others. Also, most sensors only measure scour depth at one location and near the pier. Thus, the objective is to design a simple, low cost, scour hole topography monitoring system that could better characterize the entire depth, shape, and size of bridge scour holes. The design is based on burying a robust, waterproofed, piezoelectric sensor strip in the streambed. When scour erodes sediments to expose the sensor, flowing water excites it to cause the generation of time-varying voltage signals. An algorithm then takes the time-domain data and maps it to the frequency-domain for identifying the sensor's resonant frequency, which is used for calculating the exposed sensor length or scour depth. Here, three different sets of tests were conducted to validate this new technique. First, a single sensor was tested in ambient air, and its exposed length was varied. Upon verifying the sensing concept, a waterproofed prototype was buried in soil and tested in a tank filled with water. Sensor performance was characterized as soil was manually eroded away, which simulated various scour depths. The results confirmed that sensor resonant frequencies decreased with increasing scour depths. Finally, a network of 11 sensors was configured to form a distributed monitoring system in the lab. Their exposed lengths were adjusted to simulate scour hole formation and evolution. Results showed promise that the proposed sensing system could be scaled up and used for bridge scour topography monitoring.

        Application of recursive SSA as data pre-processing filter for stochastic subspace identification

        Loh,,Chin-Hsiung,Liu,,Yi-Cheng Techno-Press 2013 Smart Structures and Systems, An International Jou Vol.11 No.1

        The objective of this paper is to develop on-line system parameter estimation and damage detection technique from the response measurements through using the Recursive Covariance-Driven Stochastic Subspace identification (RSSI-COV) approach. To reduce the effect of noise on the results of identification, discussion on the pre-processing of data using recursive singular spectrum analysis (rSSA) is presented to remove the noise contaminant measurements so as to enhance the stability of data analysis. Through the application of rSSA-SSI-COV to the vibration measurement of bridge during scouring experiment, the ability of the proposed algorithm was proved to be robust to the noise perturbations and offers a very good online tracking capability. The accuracy and robustness offered by rSSA-SSI-COV provides a key to obtain the evidence of imminent bridge settlement and a very stable modal frequency tracking which makes it possible for early warning. The peak values of the identified $1^{st}$ mode shape slope ratio has shown to be a good indicator for damage location, meanwhile, the drastic movements of the peak of $2^{nd}$ mode slope ratio could be used as another feature to indicate imminent pier settlement.

        Effects of Palm Kernel Cake on Performance and Blood Lipids in Rats

        Loh,,T.C.,Foo,,H.L.,Tan,,B.K.,Jelan,,Z.A. Asian Australasian Association of Animal Productio 2002 Animal Bioscience Vol.15 No.8

        Palm kernel cake (PKC), a by-product of oil palm seeds after extraction of their oil. The aim of this study was to investigate the effects of different levels of PKC on growth performance and blood lipids in rats. A total of 64 Sprague-Dawley (8 weeks of age) male rats were assigned individually to four treatments with different levels of PKC in the diet: 0, 15, 20 and 25%. No differences (p<0.05) were found in daily feed intake (6-8 g/day), body weight, growth rate and epididymal fat weight for all the dietary groups. Plasma protein and very low density lipoprotein (VLDL) triacylglycerol (TG) were higher (p<0.05) for 20% PKC fed rats than the control rats. Conversely, the plasma cholesterol and TG and VLDL-phospholipid (PL) concentrations of the control rats were higher (p<0.05) than those of PKC fed rats. The VLDL-protein, total cholesterol, free cholesterol (FC) and cholesteryl ester (CE) were not significantly different (p>0.05) among the treatment groups. Rats fed PKC had greater (p<0.05) ratios of total surface to core lipid components [(FC+PL)/(CE+TG)] than control rats. The results reflect dissimilarities of VLDL particle size between PKC treatment and control rats, where the plasma of the PKC treated rats contained more lipid rich VLDL. In conclusion, there was no adverse effect on growth performance when inclusion of PKC up to 25%. However, fibre content may affect the plasma lipid concentrations.

        Animal lectins: potential receptors for ginseng polysaccharides

        Loh,,So,Hee,Park,,Jin-Yeon,Cho,,Eun,Hee,Nah,,Seung-Yeol,Kang,,Young-Sun The Korean Society of Ginseng 2017 Journal of Ginseng Research Vol.41 No.1

        Panax ginseng Meyer, belonging to the genus Panax of the family Araliaceae, is known for its human immune system-related effects, such as immune-boosting effects. Ginseng polysaccharides (GPs) are the responsible ingredient of ginseng in immunomodulation, and are classified as acidic and neutral GPs. Although GPs participate in various immune reactions including the stimulation of immune cells and production of cytokines, the precise function of GPs together with its potential receptor(s) and their signal transduction pathways have remained largely unknown. Animal lectins are carbohydrate-binding proteins that are highly specific for sugar moieties. Among many different biological functions in vivo, animal lectins especially play important roles in the immune system by recognizing carbohydrates that are found exclusively on pathogens or that are inaccessible on host cells. This review summarizes the immunological activities of GPs and the diverse roles of animal lectins in the immune system, suggesting the possibility of animal lectins as the potential receptor candidates of GPs and giving insights into the development of GPs as therapeutic biomaterials for many immunological diseases.

        Effect of Fermented Fruits on the Growth Performance, Shedding of Enterobacteriaceae and Lactobacilli in Post-weaning Pigs

        Loh,,T.C.,Foo,,H.L.,Lee,,K.L.,Lim,,Y.Z.,Kufli,,C.N. Asian Australasian Association of Animal Productio 2003 Animal Bioscience Vol.16 No.11

        The aim of this study was to investigate the effect of fermented fruits (FF) on the growth performance, Enterobacteriaceae and Lactobacillus counts in faeces of the post-weaning piglets. A total of twenty-four 4 weeks old Landrace${\times}$ Large White${\times}$Duroc with initial body weight of 6 kg were used in this study. The piglets were housed individually in metabolic cage and randomly assigned to four groups with six piglets per group. The piglets were fed on basal diet without antibiotic (AF), basal diets with antibiotic (Ab), basal diet with 10% (w/w) fermented fruit (10% FF) and basal diet with 20% (w/w) fermented fruit (20% FF). Faecal samples were taken directly from the rectum of each piglet and cultured for Enterobacteriaceae and Lactobacillus counts. In the growth performance, the piglets of Ab and 10%FF had significantly higher (p<0.05) average daily gain than those of 20%FF. However, no differences (p>0.05) were observed between AF, Ab and 10%FF. Studies showed that the use of fermented fruits (FF) could significantly (p<0.05) reduce Enterobacteriaceae population in piglets' faeces compared to the use of normal feed (AF) and antibiotic (Ab). However, the Lactobacillus population in the faeces was increased in those piglets fed with diets added with FF.

        Orthogonal Stimulus-Response as a Tool to Formulate Traditional Chinese Medicinal Herbal Combination - New Scientific-Based TCM Herbal Formulating Method -

        Loh,,Yean,Chun,Tan,,Chu,Shan,Yam,,Mun,Fei,Oo,,Chuan,Wei,Omar,,Wan,Maznah,Wan KOREAN PHARMACOPUNCTURE INSTITUTE 2018 Journal of pharmacopuncture Vol.21 No.3

        Objectives: There is an increasing number of complex diseases that are progressively more difficult to be controlled using the conventional "single compound, single target" approach as demonstrated in our current modern drug development. TCM might be the new cornerstone of treatment alternative when the current treatment option is no longer as effective or that we have exhausted it as an option. Orthogonal stimulus-response compatibility group study is one of the most frequently employed formulas to produce optimal herbal combination for treatment of multi-syndromic diseases. This approach could solve the relatively low efficacy single drug therapy usage and chronic adverse effects caused by long terms administration of drugs that has been reported in the field of pharmacology and medicine Methods: The present review was based on the Science Direct database search for those related to the TCM and the development of antihypertensive TCM herbal combination using orthogonal stimulus-response compatibility group studies approach. Results: Recent studies have demonstrated that the orthogonal stimulus-response compatibility group study approach was most frequently used to formulate TCM herbal combination based on the TCM principles upon the selection of herbs, and the resulting formulated TCM formula exhibited desired outcomes in treating one of global concerned complex multi-syndromic diseases, the hypertension. These promising therapeutic effects were claimed to have been attributed by the holistic signaling mechanism pathways employed by the crude combination of herbs. Conclusion: The present review could serve as a guide and prove the feasibility of TCM principles to be used for future pharmacological drug research development.
