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.

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.

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.

Sociodemographic Predictors of Recall and Recognition of Colorectal Cancer Symptoms and Anticipated Delay in Help-Seeking in a Multiethnic Asian Population

Loh, Kwong Weng,Majid, Hazreen Abdul,Dahlui, Maznah,Roslani, April Camilla,Su, Tin Tin Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.6

Background: Colorectal cancer is the second most common cancer in Malaysia. The prognosis of the disease is excellent if detected at an early stage, but the majority of Malaysian patients present at late stages. We aimed to assess the awareness of cancer warning signs and anticipated delay in help-seeking as possible contributors to this phenomenon. Materials and Methods: A population-based cross-sectional survey using the Colorectal Cancer Awareness Measure was initiated in Perak, Malaysia. A total of 2,379 respondents aged 18 years and above were recruited using a multi-stage sampling in five locations. Analysis of covariance was used to examine independent sociodemographic predictors of scores for symptom awareness. Results: Younger age, being female, a higher education, and higher income were significantly associated with better scores for both recall and recognition of warning symptoms. Among the ethnic groups, Malays had better recognition of symptoms whereas Chinese recalled the most symptoms. Passing bloody stool was associated with the least anticipated delay and unexplained anal pain had the highest anticipated delay. Conclusions: The level of awareness across all ethnicities in Malaysia is generally low, especially among minorities. Targeted public education, which is culturally and linguistically appropriate, should be developed to encourage early help-seeking and improve clinical outcomes.

Experimental and Analytical Study of a Cooling Mechanism Using Acoustic Streaming by Ultrasonic Vibrations

Loh, Byoung-Gook,Lee, Dong-Ryul 한국소음진동공학회 2003 한국소음진동공학회 논문집 Vol.13 No.9

A cooling mechanism using acoustic streaming by ultrasonic vibrations and associated convective heat transfer enhancement is investigated experimentally and analytically. Acoustic streaming pattern and associated heat transfer characteristics are presented. Analytical transient temperature profile of the heated plate following Nyborgs theory is accomplished along with experimental measurement. A temperature drop of 30 C is obtained in 4 minutes with vibration amplitude of 10${\mu}{\textrm}{m}$. As the vibration amplitude is further increased to 25${\mu}{\textrm}{m}$ a temperature drop of 40 C is achieved that is the maximum temperature drop obtained with the current experimental apparatus. Analytical heat transfer solutions verified a temperature drop of 4$0^{\circ}C$ with a vibration amplitude of 25${\mu}{\textrm}{m}$ at 28.4 kHz which is experimentally obtained.

An Objective Approach to Deriving the Clinical Performance of Autoverification Limits

Loh Tze Ping,Tan Rui Zhen,Lim Chun Yee,Markus Corey 대한진단검사의학회 2022 Annals of Laboratory Medicine Vol.42 No.5

This study describes an objective approach to deriving the clinical performance of autoverification rules to inform laboratory practice when implementing them. Anonymized historical laboratory data for 12 biochemistry measurands were collected and Box-Cox-transformed to approximate a Gaussian distribution. The historical laboratory data were assumed to be error-free. Using the probability theory, the clinical specificity of a set of autoverification limits can be derived by calculating the percentile values of the overall distribution of a measurand. The 5th and 95th percentile values of the laboratory data were calculated to achieve a 90% clinical specificity. Next, a predefined tolerable total error adopted from the Royal College of Pathologists of Australasia Quality Assurance Program was applied to the extracted data before subjecting to Box-Cox transformation. Using a standard normal distribution, the clinical sensitivity can be derived from the probability of the Z-value to the right of the autoverification limit for a one-tailed probability and multiplied by two for a two-tailed probability. The clinical sensitivity showed an inverse relationship with between-subject biological variation. The laboratory can set and assess the clinical performance of its autoverification rules that conforms to its desired risk profile.

Acoustic Levitation and Rotation Produced by Ultrasonic Flexural Vibration

Loh, Byoung-Gook 한국소음진동공학회 2004 한국소음진동공학회 논문집 Vol.14 No.5

Acoustic levitation induced by ultrasonic flexural vibration at 28.4 KHz with a vibration amplitude of 10 micrometers is presented. Levitation of multiple objects along the length of the beam in a gap of 8.3 mm which is the half of acoustic wavelength is experimentally demonstrated. Analytical analysis predicts that levitated objects for the gap of half-the wavelength converges to the center of the gap, which is experimentally verified. It is observed that levitated objects with well-balanced mass distribution are set into rotation due to acoustic streaming. For cylinder-shaped Styrofoam with a diameter of 1.8 mm and a length of 3 mm, measured rotational velocity is 2400 revolution per minute. Applications of standing wave field levitation (SWFL) include manipulation of biological cells and blood constituents in biotechnology, and fine powder in material engineering.

ROCKET: A Robust Parallel Algorithm for Clustering Large-Scale Transaction Databases

LOH, Woong-Kee,MOON, Yang-Sae,AHN, Heejune The Institute of Electronics, Information and Comm 2011 IEICE transactions on information and systems Vol.94 No.10

<P>We propose a robust and efficient algorithm called ROCKET for clustering large-scale transaction databases. ROCKET is a divisive hierarchical algorithm that makes the most of recent hardware architecture. ROCKET handles the cases with the small and the large number of similar transaction pairs separately and efficiently. Through experiments, we show that ROCKET achieves high-quality clustering with a dramatic performance improvement.</P>

Suppression of 5' splice-sites through multiple exonic motifs by hnRNP L

Loh, T.J.,Choi, N.,Moon, H.,Jang, H.N.,Liu, Y.,Zhou, J.,Zheng, X.,Shen, H. Elsevier Science 2017 Biochimica et biophysica acta. Gene regulatory mec Vol.1860 No.3

Selection of 5' splice-sites (5'SS) in alternative splicing plays an important role in gene regulation. Although regulatory mechanisms of heterogeneous nuclear ribonucleoprotein L (hnRNP L), a well-known splicing regulatory protein, have been studied in a substantial level, its role in 5'SS selection is not thoroughly defined. By using a KLF6 pre-mRNA alternative splicing model, we demonstrate in this report that hnRNP L inhibits proximal 5'SS but promotes two consecutive distal 5'SS splicing, antagonizing SRSF1 roles in KLF6 pre-mRNA splicing. In addition, three consecutive CA-rich sequences in a CA cassette immediately upstream of the proximal 5'SS are all required for hnRNP L functions. Importantly, the CA-cassette locations on the proximal exon do not affect hnRNP L roles. We further show that the proximal 5'SS but not the two distal 5'SSs are essential for hnRNP L activities. Notably, in a Bcl-x pre-mRNA model that contains two alternative 5'SS but includes CA-rich elements at distal exon, we demonstrate that hnRNP L also suppresses nearby 5'SS activation. Taken together, we conclude that hnRNP L suppresses 5'SS selection through multiple exonic motifs.
