OCI and ROCSAT-1 Development, Operations, and Applications

Chen, Paul,Lee, L. S.,Lin, Shin Fa 대한원격탐사학회 1999 International Symposium on Remote Sensing Vol.15 No.1

This paper describes the development, operations, and applications of ROCSAT-1 and its Ocean Color Imager (OCI) remote-sensing payload. It is the first satellite program of NSPO. The satellite was successfully launched by Lockheed Martin's Athena on January 26, 1999 from Cape Canaveral, Florida. ROCSAT-1 is a LEO experimental satellite. Its circular orbit has an altitude of 600 kilometers and an inclination angle of 35 degrees. The satellite is designed to carry out scientific research missions, including ocean color imaging, experiments on ionospheric plasma and electrodynamics, and experiments using Ka-band (20-30 GHz) communication payloads. The OCI paylaod is utilized to observe the ocean color in 7 bands (including one redundant band) of Visible and Near-Infrared (434 nm-889 nm) range with the resolution of 800m square and the swath of 702 km. It employs high performance telecentric optics, push broom scanning method using Charge Coupled Devices and large scale integrated circuit chips. The water leaving radiance is estimated from the total inputs to the OCI, including the atmospheric scattering. The post process estimates the water leaving radiance and generates different end products. The OCI has taken images since March 1999 after completing the early orbit checkout. Analyses have been performed to evaluate the performances of the instrument in orbit and to compare them with the pre-launch test results This paper will also describe the ROCSAT-1 mission operations. Four mission phases defined during the operations life cycle will be introduced. The spacecraft operating modes and ROCSAT Ground Segment operations will also be described. Finally, the contingency operations and its management process will be delineated.

The 5p15.33 Locus Is Associated with Risk of Lung Adenocarcinoma in Never-Smoking Females in Asia

Hsiung, Chao Agnes,Lan, Qing,Hong, Yun-Chul,Chen, Chien-Jen,Hosgood III, H. Dean,Chang, I-Shou,Chatterjee, Nilanjan,Brennan, Paul,Wu, Chen,Zheng, Wei,Chang, Gee-Chen,Wu, Tangchun,Park, Jae Yong,Hsiao, Public Library of Science 2010 PLoS genetics Vol.6 No.8

<▼1><P>Genome-wide association studies of lung cancer reported in populations of European background have identified three regions on chromosomes 5p15.33, 6p21.33, and 15q25 that have achieved genome-wide significance with p-values of 10<SUP>−7</SUP> or lower. These studies have been performed primarily in cigarette smokers, raising the possibility that the observed associations could be related to tobacco use, lung carcinogenesis, or both. Since most women in Asia do not smoke, we conducted a genome-wide association study of lung adenocarcinoma in never-smoking females (584 cases, 585 controls) among Han Chinese in Taiwan and found that the most significant association was for rs2736100 on chromosome 5p15.33 (p = 1.30×10<SUP>−11</SUP>). This finding was independently replicated in seven studies from East Asia totaling 1,164 lung adenocarcinomas and 1,736 controls (p = 5.38×10<SUP>−11</SUP>). A pooled analysis achieved genome-wide significance for rs2736100. This SNP marker localizes to the <I>CLPTM1L</I>-<I>TERT</I> locus on chromosome 5p15.33 (p = 2.60×10<SUP>−20</SUP>, allelic risk = 1.54, 95% Confidence Interval (CI) 1.41–1.68). Risks for heterozygote and homozygote carriers of the minor allele were 1.62 (95% CI; 1.40–1.87), and 2.35 (95% CI: 1.95–2.83), respectively. In summary, our results show that genetic variation in the <I>CLPTM1L-TERT</I> locus of chromosome 5p15.33 is directly associated with the risk of lung cancer, most notably adenocarcinoma.</P></▼1><▼2><P><B>Author Summary</B></P><P>Worldwide, approximately 15% of lung cancer cases occur among nonsmokers. Genome-wide association studies (GWAS) of lung cancer conducted in populations of European background have identified three regions on chromosomes 5, 6, and 15 that harbor genetic variants that confer risk for lung cancer. Prior studies were conducted primarily in cigarette smokers, raising the possibility that the associations could be related to tobacco use, lung carcinogenesis, or both. A GWAS of lung cancer among never-smokers is an optimal setting to discover effects that are independent of smoking. Since most women in Asia do not smoke, we conducted a GWAS of lung adenocarcinoma among never-smoking females (584 cases, 585 controls) in Taiwan, and observed a region on chromosome 5 significantly associated with risk for lung cancer in never-smoking women. The finding was independently replicated in seven studies from East Asia totaling 1,164 lung adenocarcinomas and 1,736 controls. To our knowledge, this study is the first reported GWAS of lung cancer in East Asian women, and together with the replication studies represents the largest genetic association study in this population. The findings provide insight into the genetic contribution of common variants to lung carcinogenesis.</P></▼2>

EXTERNAL COSTS OF INLAND CONTAINER TRANSPORTATION

Paul T-W Lee,Kai-Chieh Hu,Tao Chen,Jo-Ping Hsiung 인하대학교 정석물류통상연구원 2008 인하대학교 정석물류통상연구원 학술대회 Vol.2008 No.3

This paper aims to explore the external costs of inland container transportation in Taiwan, by analyzing the origin and destination of current container cargo in Taiwan, after reviewing an extensive literature survey of methods of external costs. A comparison of external costs between truck and SSS by corridor is made by using a model developed in this paper. Based on the findings that external costs of SSS is considerably lower than truck transport mode and can be an alternative of modal split for current inland container cargo transportation, we discuss the significance and managerial implications of SSS from the perspective of green logistics. In so doing, a top-down approach is employed for developing government policies, which aim to not only reduce the external costs of inland container transportation but also promote SSS in Taiwan.

Interface-State Modeling of <tex> $\hbox{Al}_{2}\hbox{O}_{3}$ </tex>–InGaAs MOS From Depletion to Inversion

Chen, Han-Ping,Yuan, Yu,Yu, Bo,Ahn, Jaesoo,McIntyre, Paul C.,Asbeck, Peter M.,Rodwell, Mark J. W.,Taur, Yuan IEEE 2012 IEEE transactions on electron devices Vol.59 No.9

<P>This paper presents a detailed analysis of the multifrequency capacitance–voltage and conductance–voltage data of <TEX>$\hbox{Al}_{2}\hbox{O}_{3}/\hbox{n-InGaAs}$ </TEX> MOS capacitors. It is shown that the widely varied frequency dependence of the data from depletion to inversion can be fitted to various regional equivalent circuits derived from the full interface-state model. In certain regions, incorporating bulk-oxide traps in the interface-state model enables better fitting of data. By calibrating the model with experimental data, the interface-state density and the trap time constants are extracted as functions of energy in the bandgap, from which the stretch-out of gate voltage is determined. It is concluded that the commonly observed decrease of the 1-kHz capacitance toward stronger inversion is due to the increasing time constant for traps to capture majority carriers at the inverted surface.</P>

Korea-ASEAN Free Trade Agreement

Paul T-W Lee,Tsung-Chen Lee,Tzu-Han Yang 인하대학교 정석물류통상연구원 2013 JOURNAL OF INTERNATIONAL LOGISTICS AND TRADE Vol.11 No.1

This paper aims to explore the impacts of the recent development of Korean free trade agreements (FTAs) on its seaborne trade volumes. The paper firstly estimates the changes in cargo value flows caused by Korea-EU FTA, Korea-USA FTA and Korea-ASEAN FTA using a global computable general equilibrium model named Global Trade Analysis Project (GTAP) and its most recent database - version 7 with 2004 as the base year. Then a set of systematic conversion factors transferring trade value flows to volume flows of different types of commodities is calibrated according to the United Nations COMTRADE database and is used to convert the GTAP trade value flows into volume flows. Having indentified maritime cargo flows by different commodity types, this paper attempts to draw implications for maritime logistics policy in order to facilitate the trade of Korean merchandises and to propose key competitive strategy for the maritime container transport networking and logistics service providers in the Korean logistics industry.
