Optimal Timing of Purchasing Decisions for Airplane Tickets and Hotels. An Example in the UK.
Hao-Te LU,Wan-Yu,HSU,Chih-Yao,YI 세계문화관광학회 2012 International Journal of Culture and tourism Resea Vol.5 No.1
Customers usually like to make travel plans weeks or months ahead of the travel schedule. Therefore, they can take extra time to search information they need in order to purchase the products at the lowest possible price. Accordingly, this study bases on the revenue management (or yield management) to examine the prices of two categories, airplane tickets and hotels, over a period of eight weeks in order to observe how the prices cycle up and down over time. The aim of this study is to investigate whether there is an optimal purchasing time for any of the products. A structured observation, often also called systematic observation was conducted by this study to investigate the two categories of travel products. The study reveals that prices for the products assume an increasing trend as the date of the product consumption approaches. The implication for consumers is that they could purchase the products as early as possible to take advantage of the early prices. Although prices sometimes drop, they rarely drop lower than those the first day consumers start their search for tourism products. At end of this study, we also discuss the price variation in Taiwan and an avenue for further research.

Where Does Trust and Service Quality Reputation Come From?
Hao-Te Lu 한국문화관광학회 2011 문화관광연구 Vol.13 No.2
The term ‘business reputation’ has certainly moved into the spotlight recently. However, most studies conducted on business reputation have focused on large or multinational enterprises. Within a potentially very large topic, this research concentrates on the perception of the reputation of Taiwanese small enterprises, namely small Chinese restaurants. The motivation for this study stems from the notions about business reputation from customers’ points of view. In addition, significant frameworks reflect conceptual and empirical work which focuses on servicescape, social responsibility, trust and service quality, all of which are relatively common in Western countries. Existing studies which concentrate on Chinese societies are rather more limited and need to be expanded. The purpose of this paper is to fill in some of this research gap by discussing some of the above models in the Chinese cultural society of Taiwan. The results correspond to previous studies conducted, such as the strong relationship between servicescape and service quality, and servicescape being positively connected to trust. The role of trust is critically important in small Chinese restaurants.

Lu, Yu-Fei,Liu, Zhi-Cai,Li, Zhong-Hong,Ma, Wen-Hao,Wang, Fu-Rang,Zhang, Ya-Bing,Lu, Jian-Bang Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.3
Objective: To summarize the endoscopic screening findings in high-risk population of esophageal and gastric carcinoma and analyze influential factors related to screening. Methods: In seven selected cities and counties with high incidences of esophageal carcinoma, people at age of 40-69 were set as the target population. Those with gastroscopy contradictions were excluded, and all who were voluntary and willing to comply with the medical requirements were subjected to endoscopic screening and histological examination for esophageal, gastric cardia and gastric carcinoma in accordance with national technical manual for early detection and treatment of cancer. Results: In three years, 36,154 people were screened, and 16,847 (46.60%) cases were found to have precancerous lesions. A total of 875 cases were found to have cancers (2.42%), and among them 739 cases had early stage with an early diagnosis rate is 84.5%. Some 715 patients underwent prompt treatment and the success rate was 81.8%. Conclusions: In a high-risk population of esophageal and gastric carcinoma, it is feasible to implement early detection and treatment by endoscopic screening. Screening can identify potential invasive carcinoma, early stage carcinoma and precancerous lesions, improving efficacy through early detection and treatment. The exploratory analysis of related influential factors will help broad implementation of early detection and treatment for esophageal and gastric carcinoma.

Zeolite-templated nanoporous carbon for high-performance supercapacitors
Lu, Hao,Kim, Kyoungsoo,Kwon, Yonghyun,Sun, Xiaoming,Ryoo, Ryong,Zhao, X. S. The Royal Society of Chemistry 2018 Journal of Materials Chemistry A Vol.6 No.22
<P>Hierarchical porous carbon prepared with calcium-containing nanocrystalline beta zeolite as the template and ethylene as the carbon source at a relatively low carbonization temperature (600 °C) displayed excellent electrocapacitive properties. The presence of both micro/mesopores and surface oxygen-containing groups on the ordered porous structure, along with a high specific surface area (2280 m<SUP>2</SUP> g<SUP>−1</SUP>) and pore volume (1.95 cm<SUP>3</SUP> g<SUP>−1</SUP>) coupled with good wettability towards the electrolyte enabled the carbon to perform well as a supercapacitor electrode. This carbon electrode achieved a specific capacitance of 250 F g<SUP>−1</SUP> at a current density of 1 A g<SUP>−1</SUP> with 1 M H2SO4 as the aqueous electrolyte measured in a three-electrode system. A symmetric capacitor fabricated with the carbon as both electrodes exhibited a specific capacitance of 161 F g<SUP>−1</SUP> at a current density of 1 A g<SUP>−1</SUP>, and an excellent cycling stability. After being cycled 17 000 times and shelved for another two months, the electrode exhibited a specific capacitance of 246 F g<SUP>−1</SUP> at 1 A g<SUP>−1</SUP>, 153% of the initial capacitance, and still maintained an excellent cycle stability. Besides, an all-solid-state supercapacitor cell fabricated with this carbon as both electrodes and polyvinyl alcohol/H2SO4 gel as the electrolyte displayed an areal specific capacitance of 413 mF cm<SUP>−2</SUP> at a current density of 0.25 mA cm<SUP>−2</SUP>.</P>

A bogie frame is a key component of high-speed rail; higher requirements of the safety and stability of the bogie frame are put forward with the continuous improvement of the train speed. In this study, we first performed a strength analysis of a bogie frame according to the JIS E 4207 standard by using finite element method. Then, we did a reliability analysis of the bogie frame. The reliability problems are defined as strength reliability and resonant frequency reliability, which indicate the structural safety and stability of the bogie frame. The reliability estimation is realized by experimental design, artificial neural network and stochastic perturbation theory. Additionally, reliability-based sensitivity indices were derived to measure the parameter importance of random input variables. An illustrative example of the bogie frame with incomplete probabilistic information was used to demonstrate the applications of the proposed method for reliability and reliability-based sensitivity estimation in terms of strength and resonant frequency reliability. The results indicate that vertical loads and the material density have more of an impact on reliability than other variables of the bogie frame.

While literature focusing on the constructs of the environmental factors of servicescape and trust are relatively common in Western countries, the empirical studies which focus on the Chinese context of the restaurant service sector are rather limited and need to be expanded. The purpose of this study is to fill in some of this gap in research by analysing the relationships between servicescape, trust and customers' choice of restaurant within the Chinese cultural society in Taiwan. This study concludes that trust has a very strong positive association for customers' choice of restaurant in Taiwan. On the other hand, although empirical findings have shown that servicescape is a very important factor in affecting customers' intentions and purchasing behaviour, this study reveals that servicescape is not an important element for customers' choice of small Chinese restaurants in Taiwan. Consequently, this study suggests that for different customers from different countries with different eating cultures, the servicescape elements may not apply to all of these customers.

<B>Summary</B><P>Sequence-based variations in starch synthesis-related genes (SSRGs) exert a basic influence on the determination of eating quality in rice (<I>Oryza sativa</I> L.). This study aimed to investigate the relationship between the sequence variations from parts of 10 SSRGs and the amylose content (AC) plus rapid viscosity analysis (RVA) profiles in a heuristic rice core set by association mapping (AM). In total, 86 sequence variations were found in 10 sequenced amplicons, including 79 single-nucleotide polymorphisms (SNPs), six insertion-deletions (InDels) and one polymorphic simple sequence repeat (SSR). Among them, 61 variations were exon-based, of which 41 should lead to amino acid changes. Four subpopulations were revealed by population structure analysis based on 170 genome-wide SSR genotypes. The final AM showed a sum of four significant associations between three phenotypic indices and three sequence variations. An <I>ADP-glucose pyrophosphorylase small unit 1</I> (<I>OsAGPS1</I>) SNP (A-G) was significantly associated with increased AC (<I>P</I><0·001, <I>R</I><SUP>2</SUP>=15·6%), while a 12-bp deletion of <I>AGPase large unit 4</I> (<I>OsAGPL4</I>) was significantly related to the decreased breakdown viscosity (BDV) (<I>P</I><0·001, <I>R</I><SUP>2</SUP>=16·6%) in both general linear model (GLM) and mixed linear model (MLM). This study provides a new perspective of allele mining for breeding strategies based on marker-assisted selection.</P>
