  • Hydrogels for medical devices such as hydrophilic dressing, moisturizing healing band, hydrophilic intravenous catheter and soft contact lens were evaluated for their cytotoxicity according to the International Organization for Standardization (ISO) procedures. To test indirect cytotoxicity of hydrogel products, dissolution medium and dissolution condition were selected based on the guideline for medical devices. Cytotoxicity was low in all the case of hydrogel products. Soft contact lens showed no significant difference in dissolution between complete medium and saline. Currently, there is no specific guidelineto test hydrogel for medical devices in Korea with consideration of characteristics of hydrogel. Thus, proper method of cytotoxicity evaluation should be selected depending on the characteristics and usages of hydrogels for medical devices.

  • While the existing research took approach method that uniformly divided the cultural difference between specific countries into individualism - collectivism in the dimension of comparative culture, this research defines the cultural sense of value of domestic university students and company employees in accordance with horizontalism-verticalism pattern within it to corroboratively define the diverse effects of advertisements of standardization and localization of global enterprises. Researching the difference of cultural sense of value owing to this generation of Korean university students and company employees, Korean university students showed prominent propensity of vertical-individualism value and company employees, propensity of horizontal-collectivism value. Researching comparatively the effect of advertisements for standardization and localization of global enterprises in connection with Korean university students and company employees, it turned out Korean university students prominently prefer localization advertisement in the TV advertisement of global enterprises and company employees, standardization advertisement. Especially, the difference between standardization advertisement and localization advertisement of university students and company employees was very remarkable in trademark attitude and advertisement information rather than advertisement attitude. With respect to model appearing in the advertisement, it turned out university students prefer localization advertisement where domestic models appear and company employees prefer standardization advertisement where foreign models appear.

  • The equalization policy needs various factors-standardization of educational environment, standardization of learning method, standardization of teacher ability, etc. Especially the standardization of educational environment is the base of various factors. But the recent educational environment condition of high school is not equal. The purpose of this study is to provide basic data for equal learning environment condition in high school applying departmentalized classroom system. This study has progressed through analyzing on 9 remodelling case of high school in Gangwon-Do. The method of this study is visiting high schools that operate the system, grasping the condition for environment composition, and investigating and analyzing practical use of the environment. The results of this study are summarized as follows: 1) The space compositions for departmentalized classroom system are generally desirable, but some schools take irrational space composition, especially on home base-teacher laboratory, classroom-teacher laboratory. 2) The space area distributions are different in every school. This result is based on not taking standard criterion on space area distribution.

  • This paper presents about the activities of speech database standardization in ETRI. Recently, with the support of government, ETRI and SiTEC have been gathering the large speech corpus for the domestic speech related companies. First, due to the lack of sharing the knowledge of speech database specification, the distributed speech database has a different format. Hence it seems to be needed to have the same format as soon as possible. ETRI and SiTEC are trying to find the better representation format of speech database. Second, we introduce a new description method of the annotation information of speech database. As one of the structured description method, XML based description will be applied to represent the metadata of the speech database. It will be continuously revised through the speech technology standard forum during this year.

  • This study is under doing to suggest application manual using assembling reference plane design & standard finish material basis upon material classification code as a tool of a linkage between building design and construction standarization in order to enlarge the applicability of house building material that is produced by the module plant. We can say the goal of building standardization intend not only the improvement of construction productibility but also guarantee of subsequent performance through automatization basis upon informationalization of building design. For a etabilishing of this condition, it is neccessary to link the standardization's result of material--design--construction field. According to this neccessity, we are going to suggest information factor that can make relative business manager easily approach to the standardization practical task.

  • Objective : For the standardization and quality control of eleutheroside E in Eleutherococcus species, HPLC analysis was performed and eleutherosdie E content was compared in 23 kinds of Eleutherococcus species collected from Korea and China. Methods : The content of eleutheroside E in stem bark of Eleutherococcus species collected from Korea and China were analyzed by HPLC. 0.5% phosphoric acid and acetonitrile was used as mobile solvent. Validation of HPLC analysis method was confirmed by analyzing specificity, linearity, precision and accuracy following ICH guideline. Results : Content of eleutheroside E was determined to be 1.0-1.6% and 0.5-0.8% in Korean and Chinese E. senticosus, respectively. Content of eleutheroside E in E. sessiliflorus was 0.7-1.1% and 0.2-0.4% respectively in Korean and Chinese origin. All calibration curves showed good linear regression. The method showed good precision and accuracy with intra-day and inter-day variations of 0.880-3.442% (RSD) and 0.606-3.328% (RSD), respectively, and average recovery was of 0.141-1.363% (RSD), for the eleutheroside E analyzed. Conclusion : These results might be used to establish a criterion of eleutheroside E in Eleutherococcus species.
