Objectives: This aim of this study is to compare the reflux esophagitis improvement effects of Sepiae Os, Arcae Concha, Ostreae Concha, and Proton Pump Inhibitor(esomeprazole) through rat experiments. Methods: NO production inhibitory effect was measured by NO production amount and iNOS mRNA expression level in cell lines. iNOS, $TNF-{\alpha}$ and $p-I{\kappa}B$, and serotonin were compared using immunohistochemistry at the rat reflux esophagitis. Reflux esophagitis connection external form, lower esophageal sphincter, and gap were observed and an esophageal inflammatory indicator, IL-6 activity was also evaluated by immunohistochemistry. Results: NO production and iNOS mRNA expression was showed concentration dependent decrease in cell lines treated with Sepiae OS, Arcae Concha, and Ostreae Concha at the experiments of cell lines. In the suppression of iNOS and $p-I{\kappa}B$ at the rat reflux esophagitis, Sepiae Os treat group(SOT) and Ostreae Concha treat group(OCT) were more effective. In the increase of serotonin at the rat reflux esophagitis, ACT, MT and OCT were more effective. Damage of lower esophageal sphincter, and gap between esophageal keratin and mucosa were observed less at the SOT, ACT, OCT. In the suppression of IL-6 at the rat reflux esophagitis, SOT and OCT were more effective than GE and, SOT was more effective than MT significantly. Conclusions: The anti-inflammatory effect was the best in the SOT and lower esophageal sphincter muscle contraction was the best in the ACT at the rat reflux esophagitis. Sepiae OS was more effective than esomeprazole in the suppression of iNOS, $TNF-{\alpha}$, and IL-6.

This paper examines the diffusion of smartphones with a special emphasis on the diffusive interactions between Apple iOS and Google Android in a global context. Since the two mobile platforms were first introduced in the market, the use of smartphones has skyrocketed, suggesting that the dramatic diffusion of smartphones may be explained in part by the growth and competition of these two platforms. To study this, an extended Bass model is applied to a data set of quarterly smartphone sales between 2008 and 2013 for 15 countries. Our findings suggest that the innovation effect was more salient for iOS than for Android in developed countries, whereas the imitation effect was more striking for Android than for iOS in developing countries. Furthermore, our results from the co-diffusion model suggest that the diffusion of Android negatively affected by the diffusion of iOS, but not vice versa.

본 논문에서는 iOS 플랫폼을 위한 스마트 가상기계(Smart Virtual Machine)를 설계하고 구현하였다. iOS 플랫폼을 위한 스마트 가상기계는 가상기계 기반의 컴파일러가 C/C++나 Java 언어로 작성된 프로그램과 의미적으로 동등한 중간 코드를 생성하면 이를 입력으로 받아 실행시켜주는 프로그램이다. 스마트 가상기계는 실행 파일인 SEF(Smart Executable Format) 파일을 입력으로 받아 실행하며, SEF 로더와 인터프리터, 내장 라이브러리, 실행 환경으로 구성되어 있다. 스마트 가상기계는 스마트 기기 등에 탑재되어 하드웨어 독립적으로 실행되며 어플리케이션 형태로 실행이 가능하므로 플랫폼에 독립적인 장점을 가진다. 또한, 프로그래머는 개발 언어의 제약 없이 프로그램을 작성할 수 있고, 프로그램을 플랫폼 독립적으로 실행할 수 있다.

iPhone and Smart Phone domestic markets are activated with domestic coming out of galaxy S together and the users are increasing. It follows hereupon and with forensic techniques for the cellular phone relation criminal evidence collection of data of existing the mobile forensic engineering research is necessary in about Smart Phone where it has become new techniques and WiFi etc. Convergence. It respects Smart Phone OS star forensic technique and a tool research, iPhone Apple MAC OS X and it researches galaxy S Google Android from the present paper. Smart it uses SYN methods with Phone OS star forensic techniques and it researches in order mobile forensic description below it observes it sees and forensic application methods computer forensic methods and the tools and it researches forensic techniques. The present paper research as IT powerful country will contribute in Smart Phone forensic technical advances of Korea.

최근 iPhone, iPad의 높은 사용율과 더불어 Apple 의 Mac 계열 제품에 대한 관심도 높아지고 있다. 이는 Apple의 운영체제인 Mac OS X의 사용율 증가와 함께 디지털 포렌식 수사 환경에서의 Mac OS X의 중요성이 높아짐을 의미한다. 디지털 포렌식 관점에서 Mac OS X에는 사용자의 사용 정보를 남기는 주요 Artifacts들이 있다. 외부 저장 장치 연결 정보, 어플리케이션 설치 정보, 사용자 인증 정보, 어플리케이션 설정 정보 등이 대표적인 Artifacts들이며, 이러한 정보들은 특정 위치의 로그 파일에 남게 된다. 본 논문은 Mac OS X의 대표적 Artifacts 들을 대상으로 사용 흔적 정보가 남는 파일을 분석하여 디지털 포렌식 수사 시 활용할 수 있도록 한다.

Objectives: This experimental study has been done to compare the Os Draconis composition before and after using processing method. Os Draconis has a quality for calming the liver meridian function and relaxation the mind. Methods: I studied the Os Draconis and processed Os Draconis by vinegar to compare the compositions and its' character. Results: Os Draconis is not a dinosaur's bone fossil but a mammal's bone fossil which has a Calcite mineral, an Apatite mineral, $SiO_2\;Al_2$ O, etc. Os Draconis contains a main ingredients CaO>50.00%. Processed Os Draconis which is heated and soaked in vinegar changes to weak condition Conclusion: Os Draconis is supposed to be a mammal's bone fossil. Some Os Draconis has a radioactive substance like a U, Th so we pay heed to deal with it in a medical clinic.

Background & Object : The differentiation of osteoblasts controlled by various growth factors and matrix proteins expression in bone. The aim of this study was to identify the Astragalus membranaceus that may induce the osteogenic activity in human osteoblast-like SaOS-2 cells. Methods : The osteogenic activity of Astragalus membranaceus were evaluated by WST-8 assay, ALP activity, RT-PCR analysis of VEGF, OCN, OPN, Col I mRNA, and ELISA or colorimetric analysis, and mineralization by Alizarin red staining in SaOS-2 cells. Results : Astragalus membranaceus had no effect on viability of osteoblastic cells, and dose dependently increased alkaline phosphatase (ALP) activity. Astragalus membranaceus markedly increased mRNA expression for vascular endothelial growth factor (VEGF), osteocalcin (OCN), osteopontin (OPN), and type I collagen (Col 1) in SaOS-2 cells. Extracellular accumulation of proteins such as VEGF, and Col I was increased in a dose-dependent manner. Also, Astragalus membranaceus significantly induced mineralization in the culture of SaOS-2 cells. Conclusion : This study showed that Astragalus membranaceus not affect on viability, but it enhanced ALP activity, VEGF, bone matrix proteins such as OCN, OPN and Col I, and mineralization in SaOS-2 cells. These results propose that Astragalus membranaceus plays an important role in osteoblastic bone formation, and possibly lead to the development of bone-forming drug.

Demand for "pet plants" and "planteriers" is increasing due to the increase in COVID-19 and fine dust. In this paper, Smart pots for planterior should be small in size while providing the functions for cultivation without any problems. They should provide a user interface for long-range control for user's convenience. We implemented smart pots by incorporating IoT into pots. In response to the growing number of iPhone users, we developed an iOS app for user interface and UX/UI design. By communicating with the smartphone app and a home pot server over the Internet, users can check and control the state of the pot anytime, anywhere. The server and the pot module were separated to reduce the size of the pot itself. By locating a water bottle at the bottom of the pot, we expect that it is suitable for a "planterier" because it adopts a circulating structure in which drainage flows down to the water bottle as it is.
