To activate the use of the mobile Internet, its service must be changed itself, as well as improvement of its use environment, and the changing direction must orient 'SMART SERVICE', which it provides in the fastest, easiest, most comfortable way by selecting the core information users want most. This paper suggests that the users of smartphones access diverse contents out of the mobile apps anytime and anywhere and use them conveniently, by activating social communication among the users of school information through the mobile app development suitable for Android OS.

The purpose of this study is to orient users' touchpoints in co-design experience, to identify their need via visualized experience map, to recommend valid design information in online e-customization services. A user-centered co-design experience map (UCEM) is adopted to analyze the relation between users' desire and time spent, so as to evaluate the online co-design experiences. Based on evolutionary algorithm and fuzzy theory, data of this study is collected from 30 participants. The data was analyzed by descriptive analysis in SPSS, and frequency query and word cloud in NVivo. Employing design category and evaluating users' time spent, the findings are that (a) vamp color matching is consistent with interview data; (b) supported by qualitative feedback, the virtual experience map played an important role in the co-design process and the visualized interaction process; and (c) participants prefer to get more information and professional help on color matching and exterior design. Based on the findings in design category, future work should be focused on developing a better understanding of design resource recommendations and multi-stakeholder communication.

This study is to evaluate the morality of teenagers with regard to features of justice. On the basis of the findings, an online morality level test system is designed and implemented to help students understand themselves better and to increase moral maturity through this self-test method based on Kohlberg's Morality Development Level. The main purpose of this study is to help students test and evaluate their morality, and it will be contributed to slough off egocentrism and to orient a relationship based on a mutual respect by using the embodied system. If this system can be applied successfully, an effective improvement on students' further education guidance may be gained because the test and its results are made in the system simultaneously. Also this easy and fast test system can attain much more economical effects than a written test.

In general, flat-plate solar collectors are generally fixed in place at some angles. The most common method is to orient solar collectors toward the true south, where variations up to 15 degrees east or west are acceptable and the tiIt angle of the collectors is calculated from latitude and different heating applications. However, the best angle of flat-plate collectors depends upon whether the dominant load occurs in the winter, summer, or evenly all year. Moreover, this setting angle must consider the average insolation characteristics of the region exactly. In this study, the setting angle of flat-plate solar collectors is presented for Busan area by using domestic typical meteorological year weather data, so that the fixed flat-plate solar collectors must be set as quantitatively as possible.

The objectives of this paper is to propose the pharmacoepidemiologic methodology to Research for Sasang Constitutional Pharmacology. We mainly searched "Journal of Pharmacoepidemiology and Risk Management". And we also searched "J Korean Oriental Med.", "J of Sasang Constitutional Med.", "J. Oriental Physiology & Pathology", "Korean J Orient Int Med." using these kew words - "adverse event" or "side effect" and "Sasang Contitution" or "Constitution" or "Constitutional medicine". Through the examination of the Pharmacoepidemiologic methodology and current research for sasang constitiutional pharmacology, we could establish the proposal to collect objective constitutional medical reaction. For the actualization of this proposal, the more advanced studies will have to be carried out continuously.

Meliae toosendan Fructus, the seed of Pagoda tree, Melia toosendan Sieb. et Zucc. (Meliaceae), has been used as a liver protective herbal drug in the Orient. Administration of seed oil to hyperlipedemic rats revealed the lipid lowering effects in serum and liver tissue without any toxicity in body weight increase and liver function.

It is well known that the state of existence of molecules on the surface of water changes during compression of the molecules. Electric methods, such as the measurement of the surface potential or displacement current, are also useful for investigating dynamic changes of the molecular state on the water surface during compression. Maxwell-Displacement-Current(MDC) measuring technique has been applied to the study of monolayers of Arachidic acid and L-$\alpha$-Dimyristoyl Phosphatidylcholine(L-$\alpha$-DMPC). The displacement current was generated from monolayers on a water surface by monolayer compression. Displacement current was generated in the gas state, gas/liquid state, and liquid state in the course of monolayer compression. The researchers examined diplacement current of electric conduction organic monolayer generated due to orient change of monolayers alkylchain.

Woolen fabrics were manufactured in Korea since the early prehistoric period and were manufactured and used from the period of the three Kingoms and Koryo through the Chosonera. These materials were developed in to woolen fabrics through a tradition of thou-sand years. In Korea the Orient Culture of no-madic tribes and Mesopotamia Culture of stock-farming come together and developed these original woolen fabrics cultures. During the Chosen period woolen goods were frequently manufactured and used. Those re-mains consist of various hats and shoes made up of felt. And the remains which of a kind of woolen fabrics were made from the wool materials. There were various stock farms and supplies a woolen craftsman needed the wool materials. There were various stock farms and supplies a woolen craftsman needed the wool materials. And there were especial woolen goods shops as Choung Po Joun.

Time-Of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS) and Atomic Force Microscopy (AFM) are the useful instruments to measure nanostructures of material surfaces. Surface pattern formation in blending homopolymer and diblock copolymer films was investigated as a function of film thickness and annealing conditions. In this study, surface structures of blending homopolymer [deuterated polystyrene (Mn 20,000), poly (methyl methacrylate) (Mn 18,000)] and diblock copolymer [Poly (deuteratedstyrene(d8)-b-methyl methacrylate) (Mn 19,500-18,100)] films were observed. The AFM result indicated that the nanostructures and film thickness depended on temperature, concentration and solvent. TOF-SIMS depth profiling was obtained for the lamellar morphology of symmetric dPS-b-PMMA which is found to orient parallel to the surface of the substrate. Elemental and molecular depth profiles measured in the negative ion mode by a Cs+ primary ion beam demonstrate variations in hydrogen, deuterium, carbon, oxygen, hydrocarbons and deuterated hydrocarbons within the diblock copolymer according to the depth.

Pomegranate, a small tree originating in Orient, belongs to Punicaceae family. The seeds contain an oil of which about 80% is rare trans 18 carbon fatty acid (punicic acid), and have highest botanical concentration of a sex steroid, estrone. Pharmacological properties of pomegranate extract have been studied, with anti-microbial, anti-parasitic, ant-viral, and anti-cancer effects. We have examined the estrogenic activity of the pomegranate extracts using MCP-7-ERE cells. MCF-7-ERE cells, stably transfected with pERE-Luc were treated various amount of pomegranate extract and after overnight treatments, luciferase activity were measured. Estradiol(E2) dose dependently induced luciferase activity in this cell and maximal response is obtained at 100pM E2.
