Patient safety is achieved through systematic improvement based on the knowledge and willingness of medical professionals. A systematic longitudinal curriculum for patient safety is essential to prepare medical students and professionals. The purpose of this article is to introduce our experience with a 'workshop for developing a patient safety curriculum' and to compare the results with previous studies. The workshop comprising 15 medical professors and patient safety experts met for 2 days. The Consensus Workshop method was applied, collecting opinions from all of the members and reaching consensus through the following stages: context, brainstorm, cluster, name, and resolve. The patient safety curriculum was developed by this method, covering patient safety topics and issues, and teaching and assessment methods. A total of 7 topics were extracted, 'activities for patient safety, concepts of patient safety, leadership and teamwork, error disclosure, self-management, patient education, policies.' Issues, teaching methods, and assessment methods were developed for each topic. The patient safety curriculum developed from the workshop was similar to previous curricula developed by other institutions and medical schools. The Consensus Workshop method proved to be an effective approach to developing a patient safety curriculum.

Pneumonia is an inflammation that forms at the mesopulmonum and alveolus that is also an acute infection with fever and cough. It is difficult for doctors to diagnose pneumonia in elderly patients, due to the variety of symptoms. For this reason, it, with its complications, is a major cause of death for the elderly. In this case, improvement was seen in an elderly patient diagnosed with pneumonia by X-ray, and by using Si-Kyung-Ban-Ha-Tang-Ka-Mi-Bang as a way of Kong-Bo-Kyum-Si, because in this case pneumonia was presumed Dam-Yel-Ong-Pye and Ki-Eum-Yang-Huh due to the weakness associated with old age. This thesis proposes that the elderly are better treated differently from other pneumonia patients due to the weakness that comes with old age.

Nano-sized powders of Indium Tin Oxide(ITO) were synthesized by a coprecipitation method. In order to investigate the gas sensing characteristics in the nanocrystalline ITO thick films with various particle sizes, ITO powders with the average particle diameter of 15, 30, and 70 nm respectively were synthesized. And the sensitivity of ITO thick films was measured upon exposure to a target gas($C_2$$H_{5}$ /OH) and some other Volatile Organic Compounds(VOCs), such as, toluene, methanol, benzene, chloroform. As a result, ITO thick films had high sensitivity for ethanol and higher sensitivity with smaller particle size.

Sn doped $In_2O_3$ (ITO) and ITO/Ni/ITO (INI) multilayer films were deposited on the glass substrates with a reactive magnetron sputtering system without intentional substrate heating and then the influence of the Ni interlayer on the methanol gas sensitivity of ITO and INI film sensors were investigated. Although both ITO and INI film sensors have the same thickness of 100 nm, INI sensors have a sandwich structure of ITO 50 nm/Ni 5 nm/ITO 45 nm. The changes in the gas sensitivity of the film sensors caused by methanol gas ranging from 100 to 1000 ppm were measured. It is observed that the INI film sensors show the higher sensitivity than that of the ITO single layer sensors. Finally, it can be concluded that the INI film sensor have the potential to be used as improved methanol gas sensors.

We have developed technology to fabricate large-size active matrix organic light-emitting diode (AMOLED) displays with good color purity. Using these innovations, we have developed a 40inch diagonal WXGA AMOLED full color display. Because the TFT circuitry occupies a large portion of the pixel structure, an efficient white emission OLED is essential to integrate the device onto the active matrix backplane. The development of these technologies enables OLED displays to fulfill the requirements for larger size applications such as HDTVs

Minimization of conventional propulsion device has been studied for altitude control of micro satellite. We studied micro nozzle performance and found higher significant loss for a micro nozzle with smaller nozzle throat diameter. To overcome this loss, we proposed thermal transpiration based micro propulsion system. This new system has no moving parts and can control flow by temperature gradient, and this can be an option for potential new micro propulsion system.

A successful rapid synthesis of dendritic benzyl chlorides from dendritic benzyl alcohols using methanesulfonyl chloride/$Et_3N$ as activating agents was described. In this method, each dendritic benzyl chloride can be prepared in one pot: no isolation of intermediate mesylated dendrons is required. The key steps in the syntheses of dendritic benzyl chlorides were the mesylation of the hydroxymethyl group followed by the chlorination by in-situ generated triethylammonium chloride.

Micro-/macroporous carbons (MMCs) were prepared using a hollow mesoporous silica capsule (HMSC) as a sacrificial hard template. The carbonization process after the infiltration of furfuryl alcohol into the template-free HMSC material afforded MMC materials in high yield. The hard template HMSC could be removed by HF etching without deteriorating the structure of MMC. The MMC materials were fully characterized by SEM, TEM, PXRD, XPS, and Raman spectroscopy. The replication processes were so successful that MMCs exhibited a hollow capsular structure with multimodal microporosity. Detailed textural properties of MMC materials were investigated by volumetric $N_2$ adsorption-desorption analysis at 77 K. To explore the gas sorption abilities of MMCs for other gases, $H_2$ and $CO_2$ sorption analyses were also performed at various temperatures. The multimodal MMC materials were found to be good sorbents for both $H_2$ and $CO_2$ at low pressure.

A lot of foreign objects(ceramics, pottery, bronze, glassware and coins, etc.) have been found in the archaeological sites in Korea. These foreign objects are the evidences of the cultural exchanges of that time, whose scale and routes are an important part of the studies in ancient history. So it is crucial to accumulate basic reference information such as the raw materials and the production method of these objects through scientific researches, along with archeological researches. These scientific research materials provide a basis for finding the importing route and the origin of these objects. Besides, we can find out extraordinary and distinctive production technique by comparison with tile domestic objects. This article reports the result of an analysis, performing on 36 samples of the glassware fragments excavated from the South Tomb of the Hwangnamdaechong, to verify their components and note peculiar features. We have analyzed the major and minor components of 10 elements, and then by using these data examined the differences in the composition of components, varying with the origin and color of glassware. We used the PCA(principal component analysis) as the statistical method to classify the sample in order to find out how the samples formed groups.
