As knowledge-based society comes to the fore, sharing knowledge becomes a hot issue. Among various types of knowledge, a significance of software(applications) and contents is a huge in a current society. Moreover, along with appearance of smartphone, for instance iPhone, Application Store(also known as AppStore) utilized as a common gateway for sharing software and contents, brings a big interest for many users and developers. However, prior research to understand users` behavior on AppStore has been a scant. Therefore, the main purpose of this study is to investigate the impact of key smart service environmental factors on AppStore in order to empirically explain users` psychological feelings of intention to use AppStore. Based on a well-known technology adoption model, TAM, the study incorporates three main characteristics(user, society, and service) with six constructs(Innovation, Enjoyment, Subjective Norm, Information Level, Content variety, and Cost), influencing perceived usefulness, which then affects users` intention to use AppStore. Results provide evidence that support the tested hypotheses. The implications of the findings suggest a new theoretical work for future AppStore research and offers suggestions that the researchers and practitioners of AppStore should consider regarding the development of application and contents.

The dissolution test method and an analytical procedure by HPLC were developed and validated for dobesilate calcium tablets and acepifylline tablets. These drugs were not yet characterized by the dissolution specifications in Korean Pharmaceutical Codex. So, with each reference and test drugs, we did the preliminary and standard experiments based on the Korean Pharmacopeia Guideline of dissolution testing for solid oral dosage forms. The dissolution test for dobesilate calcium tablets was carried out under sink conditions as following: dissolution medium water, paddle rotation speed 50 rpm and vessel volume 900 ml. More than 90% of its label amount was released within 30 min in this method. Also the dissolution test for acepifylline tablets was carried out under sink conditions as follows: dissolution medium water, paddle rotation speed 100 rpm and vessel volume 900 ml. More than 90% of its label amount was released within 45 min in this method. The dissolution samples were analyzed with a precise and accurate HPLC method. The developed dissolution test showed specificity, linearity, precision and accuracy within the acceptable range. The dissolution testing method described above was adequate for the purpose and may be proposed as a pharmacopeial standard to assess the performance of dobesilate calcium tablets and acepifylline tablets.

Despite the fact that the dissolution test can serve as an effective tool for drug quality control and prediction of in vivo drug performance, there are a number of drugs with no established dissolution specifications because they were developed quite a long time ago. Under this circumstances, KFDA started the new project that establishes dissolution method and specifications for drugs with no dissolution specifications listed in the Korea Pharmaceutical Codex (KPC). This project aims for promoting the appropriate management of oral solid dosage forms. Seoul regional KFDA selected 2 items, Nicametate citrate tablet and Norfloxacin capsule, for establishing dissolution specifications. We went through the following procedures to develop the dissolution method and specifications: (1) Validation of dissolution test equipment, (2) Purchase of test drugs, (3) Preliminary test with one of the test products (1 lot), (4) Validation of analysis methods (3 lots), (5) Final tests and cross tests among other laboratory to establish dissolution specifications, (6) Additional test with the other test drugs. The outcome of this study will be reflected in revision of the KPC. It is believed that the quality control and evaluation of oral solid dosage forms listed in KPC will be advanced with the revision which adds additional dissolution test and specifications for the drugs with no established dissolution specifications.
