Objectives : Considering the indigenousness of Korean medicine, the historical record was first introduced in 1946 as follows; a Chinese person, Ji-chong (知聰), brought 164 volumes of medical books to Japan via Goguryeo (高句麗) in A.D. 562. Since this event happened, Korean Oriental Medicine has been derived from Traditional Chinese Medicine because ancient Korean Medicine originated and was developed in China. The purpose of this study was to investigate the existence and role of Ji-chong in the history of medical exchanges between ancient Korea and Japan. Methods : We studied Ji-chong through ancient and modern historical literatures such as Nihon Shoki (日本書紀), the record of $Shinsen-sh{\bar{o}}jiroku$ (新撰姓氏錄), Korean Medical History (韓國醫學史), Japanese Medical History (日本醫學史), Samguk Sagi (三國史記), etc. Results : We found indications of the existence of Ji-chong and the import of Chinese medical literature to the ancient Korean peninsula by examining domestic and foreign historical literature. Especially, he was closely related to historical assumptions about the Japanese conquest of Goguryeo in A.D. 562, although without objective historical evidence and described only in modern Japanese historical records and Korean Medical History. However, substantial medical exchange toward Japan was accomplished by Korean medicine of either Goguryeo, Baekje (百濟), or Silla (新羅) dynasty until the late A.D. 6 century. Conclusions : Based on the above investigation, the idea that Ji-chong carried medical literature via Goguryeo in A.D. 562 needs to be reconsidered and the role of Ji-chong as recorded in a variety of literature and databases should be amended., Korean Oriental Medicine has been derived from Traditional Chinese Medicine because ancient Korean Medicine originated and was developed in China.

To produce well-qualified medical doctors, clinical training is a crucial part of medical education. To this end, teaching hospitals should be carefully selected and professionally managed. However, in Korea, there are no regulations or standards for training hospitals. Instead, some of the regulations that target teaching interns and residents are applied to teaching hospitals. In this study, we reviewed standards and regulations for training hospitals in other countries as a basis for proposing new standards for teaching hospitals in Korea. These new standards take into account the current environment of Korean medicine with the aim of designing appropriate educational programs for students and professional development systems for professors as well as providing educational resources and addressing the local community and international exchange opportunities.

In the medical field. the desire of the hospital information system based on the advanced computer technology has been increased because hospital staffs wanted to provide better medical services to their patients by using it. So, the electronic medical records have emerged to share and exchange medical and healthcare information stored in database. In this paper. we developed an electronic medical record system using XML. This system includes four modules : data repository. document structure manager, document writter and XML automatic generator. For the purpose of evaluating the usability of the electronic medical records of our system, we also applied it to out-patient medical records in the department of orthopedic surgery.

The objective of this study was to evaluate the chemical exchange saturation transfer (CEST) effect of amino acids and neurotransmitters, which exist in the human brain, depending on the concentration, pH, and amplitude of the saturation radiofrequency field. Phantoms were developed with asparagine (Asn), ${\gamma}-aminobutyric$ acid (GABA), glutamate (Glu), glycine (Gly), and myoinositol (MI). Each chemical had three different concentrations of 10, 30, and 50 mM and three different pH values of 5.6, 6.2, and 7.4. Full Z-spectrum CEST images for each phantom were acquired with a continuous-wave radiofrequency (RF) saturation pulse with two different $B_1$ amplitudes of $2{\mu}T$ and $4{\mu}T$ using an animal 9.4T MRI system. A voxel-based CEST asymmetry was mapped to evaluate exchangeable protons based on amide (-NH), amine ($-NH_2$), and hydroxyl (-OH) groups for the five target molecules. For all target molecules, the CEST effect was increased with increasing concentration and B1 amplitude; however, the CEST effect with varying pH displayed a different trend depending on the characteristics of the molecule. On CEST asymmetric maps, Glu and MI were well visualized around 3.0 and 0.9 ppm, respectively, and were well separated macroscopically at a pH of 7.4. The exchange rates of Asn, Glu, BABA, and Gly usually decreased with increasing pH. The CEST effect was dependent on the concentration, acidity of the target molecules, and B1 amplitude of the saturation RF pulse. The CEST effect for Asn can be observed in a 9.4T MRI system. The results of this study are based on applying the CEST technique in patients with neurodegenerative diseases when proteins in the brain are increased with disease progression.

The purpose of this work was to assess and quantify the beneficial effects of gas exchange, while testingto the various frequencies of the sinusoidal wave that was excited by the PZT actuator, for patients suffering from acute respiratory distress syndrome (ARDS) or chronic respiratory problems. Also, this paper considered a simulator to design a hollow type artificial lung, and a mathematical model was used to predict a behavior of blood. This simulation was carried out according to the Montecarno's simulation method, anda fourth order Runge-Kutta method was used to solve the equation. The experimental design and procedure are then applied to the construction of a new device to assess the effectiveness of the membrane vibrations. As a result, the vibration method is very effective in the increase of gas transport. The gas exchange efficiency for the vibrating intravascular lung assist device can be increased by emphasizing the following design features: consistent and reproducible fiber geometry, and most importantly, an active means of enhancing convective mixing of water around the hollow fiber membranes. The experimental results showed the effective performance of the vibrating intravascular lung assist device. Also, we concluded that important design parameters were blood flow rates, fiber outer diameter and oxygen pressure drop. Based on the present results, it was believed that the optimal level of blood flow rates was 200$cm^3$/min.

Many hospitals tried to exchange their medical information between them. But they could not share efficiently medical information because of their different operating systems and database systems. In this paper, we developed an XML repository(called REPOMI : An XML Repository for Medical Information)based on HL7 that can store XML medical information. REPOMI is implemented by combining EJB components based on RDBMS. By REPOMI, we can manage more easily patient information and share efficiently medical information between hospitals. Therefore, medical informations can be exchanged between hospitals and general hospitals efficiently. As a result, hospitals can offer more efficient diagnosis to patients and it saves time and cost.

Purpose - This study investigated not only social network service (SNS) characteristics' effects on continuous use intention and reliability, but also the effects of continuous use intention and reliability on purchase intention. Research design, data, and methodology - The subjects comprised 274 SNS users in their twenties. The research was conducted over three weeks from October 16, 2013 to November 6, 2013, using questionnaires. A total of 267 copies were collected; 255 copies were used after excluding unsuitable copies. Results - Marketers who used SNSs should establish a bi-directional community and SNS page information exchange. SNS marketers should exchange useful information quickly through SNS pages, to differentiate themselves from competitors. Enterprises should use SNSs for marketing, considering not only continuous use intention but also reliability, to elevate product purchase intention. Conclusions - The study had limitations. Most subjects were students aged 24 to 28 years; the findings cannot be generalized. Second, personal computers (PCs) and smartphones had similar influence. Third, the preferences and/or characteristics of each SNS type were not reflected in marketing.

With the rapid advance of information technology and the popularity of digital medical, medical information are growing, the process of hospital digitalization are gradually quicken and systems involved are more and more. HIS system mainly deals with patient information, it follows the standard of HL7. While PACS system mainly manages image information, it follows the standard of DICOM. Because HIS and PACS deal with different information and follow different standards, it is difficult to directly communicate. This paper presents a method of establishing HL7/DICOM gateway to realize the information exchange of HIS and PACS. The HL7/DICOM gateway designed in this paper is made up of three modules. First, HL7 messages and triggered events are designed to achieve the function of transaction processing module. According to the designed HL7 messages, four message interface functions are defined to accomplish the function of send/receive messages module. Finally, the algorithm of construct/parse messages is given to complete the function of construct/parse messages module. Result shows that HIS and PACS realize information exchange successfully by using the HL7/DICOM gateway Implemented in this paper.

Exchanging sheets for patients is one of the worst and one of the factors that makes the nursing environment difficult. Many beds with various functions for the patient have already been developed, but there is no device for automatically changing the sheets. In this study, we developed and tested the first automatic sheet changer for a medical bed and verified its performance. The developed automatic seat changer uses a torque limiter to properly adjust tension and exchange a dirty sheet and a new seat at the same time. The designed automatic sheet changer was experimentally confirmed to be properly operated and installed in a integrated multi-functional bed with bed sores prevention and automatic patient transfer functions.
