  • For evaluating the printing suitability of electronic copying papers in the aspect of climate conditions, 12 samples of copying papers being generally used in Korea and worldwide were collected. The copying papers were controlled by various temperature and humidity options in conditioning equipment in order to simulate the specific circumstances of dry, temperate or tropical climate, and the pre-heating system of photocopying machines during printing. As results, some copying papers showed several physical problems, especially in recycled copying papers and a normal paper with original printing faulty. These problems of copying papers were mostly resulted in extremely high moisture circumstance, and in lower levels of tensile strength and tensile stiffness. The moisture contents of copying papers during passing through the pre-heater system of photocopying machine could be rapidly decreased because paper is exposed to high temperature around the pre-heating zone. The copying paper, for example of XR3 sample, containing low moisture contents below 2% had high exfoliating possibility of toner transfer from copying paper.

  • "Science" journal is one of the world's top academic journals. Many researchers are trying to publish their work in Science, and only a few selected novel papers are accepted. However, we think that this kind of process cannot continue forever. In this paper, we show that there is a limit to the number of Science papers that can be written. Therefore, the day will come when Science cannot publish new papers anymore. Using a similar method, we estimate the maximum limit on the number of pop songs that can be composed. By extending our discussion to all kinds of digital contents, we derive a mathematical expression for the maximum number of digital contents of a certain type that can be created. These results imply that someday man will not be able to produce new papers or new digital contents anymore. This conclusion raises deep philosophical questions.

  • Thermal batteries are primary reserve batteries that use inorganic salt as electrolytes which are inactive at room temperature. The two principal heat sources that have been used in thermal batteries are heat paper and heat pellets. As soon as the heat paper, which is ignited by the initiator, in turn ignites the heat pellets, all the solid electrolytes are melted into excellent ionic conductors. However, the high combustion temperature by heat papers in thermal batteries causes thermal decomposition at the cathode, eventually leading to a thermal runaway. In this paper, we have attempted to prepare $Zr/BaCrO_4$ heat papers coated with KCl molten salt. We have also investigated the effect of a molten salt coating on the heat papers through the thermal characteristics such as calorimetric value, combustion temperature and burning rate. The calorimetric value and combustion temperature of heat papers were reduced with an increase in the molten salt coating. As a result, the molten salt coating on heat papers greatly reduced risk of a thermal runaway and improved the stability of thermal batteries.

  • Background: The recent change in pharmaceutical education system following the paradigm shift to patient-oriented pharmacy service requires an in-depth discussion to reorganize a future direction and establish a basis for maximizing social values of community pharmacy service. Objective: This study was conducted to review the current status of community pharmacy service provision in Korea based on published literatures. Methods: The electronic databases of National Digital Science Library and Electronic National Assembly Library were used to search the journal articles and dissertation papers. A search term "community pharmacy" was used and the published period was limited to papers published after year 2001, when the legal separation of prescribing and dispensing was implemented. Relevant study reports were also searched manually. Information about pharmacy service provision and study outcomes were retrieved from the selected papers, and classified by predefined individual service scope. Results: A total 33 papers reporting services provided by community pharmacies were selected (journal article 11, dissertation paper 17, and study report 5). Pharmacy services identified in these papers could be classified into prescription dispensing service, pharmaceutical care service, self medication service, other products service, and health promotion service. Twenty papers reported prescription dispensing services, three papers reported pharmaceutical care service, and only two papers reported health promotion service. Current community pharmacy services are highly dependent on prescription drugs while expanded services such as pharmaceutical care and health promotion are peripheral. Most prevalent research topic was medication counseling service (18 papers), reflecting that community pharmacists generally consider it to be the most important and fundamental service. Overall, current pharmacy services are very limited and focus on prescription dispensing service. Conclusion: At this point of time requiring expansion and quality improvement of community pharmacy services, we suggest further lively discussion to strengthen pharmacist's functional identity and set conditions for providing socially expected services.
