  • The primary purpose of this study is to investigate ASP (Application Service Provider) vendor attributes that affect ASP client satisfaction. From the relevant literature, ASP vendor attributes that might affect the ASP client satisfaction were derived from which the survey questions were formulated. The survey was conducted among the companies that have adopted ASP. Through the factor analysis of the survey results, the following vendor attributes - vendor's IT infra structure, service reliability, service flexibility, vendor stability, IS maturity, information sharing - were derived ; and the relationships between those attributes and ASP client satisfaction were explored. The result of this study revealed that IT infra, service flexibility, vendor stability are related to ASP client satisfaction. The customer satisfaction factors in the traditional outsourcing -- reliability, IS maturity, information sharing were proved to be not applied in ASP environment. This study provides ASP vendors with guidelines on how to improve their ASP strategies to satisfy clients. The results of this study can also be used by client companies as a decision basis for ASP vendor selection.

  • 62 specimens of deteriorated rice which were collected all over Korea, were classified according to their color outlooks, and the causitive microorganisms were isolated and identified. The following results were observed; 1. 62 specimens of deteriorated rice were classified according to color outlooks into 7 types; reddish yellow, light reddish yellow, light gray yellow, light reddish yellow, light gray yellow, light red, ligt gray, dark gray and rice weevil type. 2. The isolated microorganisms from 62 specimens of deteriorated rice were 44 species, 5 genera of molds, 1 species of yeast, and 14 species, 4 genera of bacteria. 3. The frequently observed microorganisms which caused the deterioration were Asp. glaucus group, Asp. oryzae, Asp. candidus, and Asp. versicolor. Among bacteria, Bacillus was dominant. 4. The relationship between color outlook types and the deterioration causing microrrganisms was not definite, but Pen. islandicum from reddish yellow, Asp. candidus and Asp. clavatus from light reddish yellow, Asp. glaucus group, Asp. candidus, Asp. versicolor and Asp. fumigatus from light red, Asp. oryzae from light gray yellow, and Asp. glaucus group and Pencillium species from light gray and dark gray were chiefly isolated. 5. As mycotoxin producing fungi, Asp. fumigatus, Pen. citrinum, Pen. islandicum, Asp. flavus, and Asp. ochraceus were detected, but their growth frequencies were not very high to be problems except Pen, islandicum which infected an imported rice sample heavily.

  • This paper presents Web service based ASP (WS-ASP) model for QR(Quick Response) system, supply chain management system in the textiles and clothing industry. The Korean textiles and clothing industry is mostly composed of medium and small-sized companies, which are not capable of recruiting If specialists and making a large scale investment in IT. ASP model not only let them obtain QR system at relatively low usage cost, but also take higher vendor risk due to high dependency. This paper argue that WS-ASP model is appropriate for QR systems by complimenting ASP model with lower vender risk, which results from re-integrating software-on-demand services distributed to several QR specialized WS-ASP vendors.

  • Aspartyl-tRNA synthetase (AspRS) exists in two different forms with respect to tRNA recognition. The discriminating enzyme (D-AspRS) recognizes only tRNA$^{Asp}$, while the non-discriminating one (ND-AspRS) also recognizes tRNA$^{Asn}$ and therefore forms both Asp-tRNA$^{Asn}$ and Asp-tRNA$^{Asp}$. Plus primary sequence distinguishes two general groups of AspRS. There is a predominantly bacterial-type, larger AspRS (about 580 aa) in addition to a shorter archaeal/eukaryotic type (about 430 aa). In vivo data made clear that discriminating and non-discriminating enzymes exist in both groups. The determinants in the protein sequence responsible for tRNA discrimination are not hewn. The AspRS from Acidithiobacillus ferrooxidans might be suggested ND-AspRS fur missing of AsnRS in genomic sequencing data. Therefore, we analyzed the AspRS from A. ferrooxidans with in vitro aminoacylation assay with E. coli unfractionated tRNA, in vivo missense suppression assay with tipA34 mutant and Northern hybridization with probes which were specific with tRNA$^{Asp}$ or tRNA$^{Asn}$. The AspRS from A. ferrooxidans produced more Asp-tRNA than that from E. coli. Only aspS gene from A. ferrooxidans suppressed trpA34 strain in minimal media without tryptophan. Only AspRS from A. ferrooxidans showed mischarged Asp-tRNA$^{Asn}$ band. Therefore, AspRS from A. ferrooxidans is definitely ND-AspRS.

  • This paper presents a state-of-the-art survey in ASP/SaaS Industry and the development strategy of ASP/SaaS business models which are issued as a new software distribution method recently. First of all, SaaS(Software as a Service) is defined as the evolutionary concept of ASP(Application Service Provider) and then the survey results of domestic ASP/SaaS providers and users are presented. In order to cope with recent and rapid If development environment, the development strategy of the ASP/SaaS business models is proposed. The development strategy suggested in the paper is used as a guideline for ASP/SaaS providers to enter into the new ASP/SaaS business and improve their competition.

  • Domestic ASP (Application Service Provider) market has been dramatically enlarged under government supports for last 10 years. However ASP industry recently has been troubled for poor performance and market saturation. In this paper, firstly I derive core service groups through using BCG matrix for ASP market size and growth rate and secondly generate major critical success factors using focused group interview for selected core service groups. Finally I would like to propose a direction of ASP industry revitalization based on above critical success factors and transition strategy to SaaS (Software as a Service).

  • Many SMEs have adopted ASP models which have brought various benefits to SMEs such as decreasing the total cost, using new IT technology, enhancing the maintenance, and implementing the information systems rapidly. Ministry of Information and Communication had implemented the ASP diffusion project for the ASP venders and SMEs between 2001 and 2003. As results of this project, various industries adopted the ASP applications of which the performance was enhanced, and then the competitiveness of the ASP vendors in Korea was increased. The purpose of this study is to make a strategy of the penetration into China market for ASP services which have competitive advantages. This study uses various research methods such as questionnaire survey, visiting SMEs in china and making interviews. This study shows the current status of Chines ASP market, the several cases of using ASP services, and questionnaire analyses(service recognition, service requirement and factors and infrastructure, business environment and supporting organizations etc) of ASP demand. And finally this study proposes several strategic considerations in entering China market and suggests several support policies for supporting Korean ASPs.

  • Objective: To investigate the association between xeroderma pigmentosum group D (XPD) Asp312Asn polymorphism and esophageal cancer (EC) susceptibility by meta-analysis. Methods: We searched PubMed up to April 9th, 2012, to identify relevant papers, and 8 published case-control studies including 2165 EC patients and 3141 healthy controls were yielded. Odds ratios (ORs) with relevant 95% confidence intervals (CIs) were applied to assess the association between XPD Asp312Asn polymorphism and EC susceptibility with the Comprehensive Meta-Analysis software, version 2.2. Results: Overall, the meta-analysis results suggested the XPD Asp312Asn polymorphism to be significantly associated with EC susceptibility [(Asn/Asn+Asp/Asn) vs. Asp/Asp: OR=1.20, 95%CI=1.05-1.36, p=0.01; and Asp/Asn vs. Asp/Asp: OR=1.15, 95%CI =1.01-1.31, p=0.04]. In the subgroup analysis by ethnicity and cancer type, significantly associations were found for Caucasian populations [(Asn/Asn+Asp/Asn) vs. Asp/Asp: OR=1.26, 95%CI =1.08-1.47, p<0.001; Asp/Asn vs. Asp/Asp: OR=1.19, 95%CI =1.02-1.40, p=0.03] and esophageal squamous cell carcinoma [(Asn/Asn+Asp/Asn) vs. Asp/Asp: OR=1.19, 95%CI=1.01-1.41, p=0.04]. There was no heterogeneity and no publication bias existed. Conclusions: This meta-analysis shows that the XPD Asp312Asn polymorphism may be a risk factor for developing EC, especially for Caucasian populations and esophageal squamous cell carcinoma.
