Objective : Two famous medical doctors, Yoo Itae(以泰, 爾泰) and Riu Euitae(義泰), have been well known in academic world and public in Sancheong-gun. Yoo Itae is the progenitor of Majinhak which is the therapy for measles, he wrote a "Majinpyun" as the first book of therapy for measles in Chosun. Riu Euitae, meanwhile, is a fictional medical doctor and a teacher of Heo Jun who became real without confirmation of historical truths by Roh Jeongwoo who heard about a name, Yoo Itae. Roh's assertion was quoted in the report of literatures, papers, novel, and telecast without verification. His assertion is exposed in novel and media and it has seriously distorted the history. The purpose of this study is to rectify the historical distortion. Methods : Various references study was performed. Confirmed a family tree, birth and death year, birthplace, sepulture, words on a tombstone, writing, collections of works anthology and the existence of keepsake. Investigated records of royal family, Sancheong-gun papers, Sancheong Hyanggyo papers, Dongyuhagan, Chosun Hanryuseungram and the record of Sawoo Munjip(anthology). Analyzed Roh Jungwoo's conversation that tells Riu Euitae is a teacher of Heo Jun and contents of an encyclopedia. Listened to testimony of descendants and assertions of historian in rural area. Verified voice recording on books taken from at birthplace and the space of activity. Results : Yoo Itae is well shown in various records and medical writing books, whereas Riu Euitae does not. Riu Euitae is not a real person in the history. Roh Jeongwoo who asserts Riu Euitae is a teacher of Heo Jun admits his mistake. But, the encyclopedia record describing Riu Euitae is a teacher of Heo Jun, government official at Sancheong district office, historians in rural area, historians in rural area who made a family shrine, gravestone, a statue, memorial, historic site of Riu Euitae on Jinju Rui could not suggest any evidences for the existence of Riu Euitae and for record Riu Euitae is a teacher of Heo Jun. Conclusion : Riu Euitae is neither a real person in the history nor a teacher of Heo Jun. Riu Euitae came from pronunciation confusion between 'I' and 'Eui' in Kyungsang province. Riu Euitae is Yoo Itae on Geochang Yoo who was a medical doctor of King, Sukjeong and wrote medical books including , , .

Purpose: The aims of this study were to evaluate effects of massage therapy and the attachment promotion program with autistic children. Method: A quasi-experimental design was conducted with a convenience sample of 44 autistic children. The experimental group (n= 23) attended the massage therapy and the attachment promotion program for 4 months. The control group (n=21) only had the attachment promotion program. Measurements were made twice for both groups using the social maturity scale and child autism rating scale. Recording of mother-child attachment was done for 15 minutes in only the experimental group twice using video equipment. Results: After 4 months of interventions, there was significant difference on social maturity (F=9.01, p=.005) between the groups. However, there was no significant difference on CARS ((F=2.47, p=.124). The total scores of mother-child attachment between pre- and post-interventions showed a significant difference (Z=-3.42, p=.001). Conclusion: The results showed that massage therapy and the attachment promotion program might be an effective way for providing a chance to increase social maturation and to increase attachment between mother and autistic child.

Multi-valued decision making for transitional stochastic events was newly derived based on conditional probability of knowledge database which included experts'knowledge and experience. The proposed multi-valued decision making was successfully adopted to the determination of the five levels of the vigilance of a subject during the EEG (electroencephalogram) recording; awake stage (stage W), and sleep stages (stage REM (rapid eye movement), stage 1, stage 2, stage $\sfrac{3}{4}$). Innovative feature of the proposed method is that the algorithm of decision making can be constructed only by use of the knowledge database, inspected by experts. The proposed multi-valued decision making with a mathematical background of the probability can also be applicable widely, in industries and in other medical fields for purposes of the multi-valued decision making.

This study aims to investigate how the game based FES paradigm influences on EEG spectrum. Thirteen subjects were recruited for this study. We selected Fp1, Fp2, F3, F4, T3, T4, P3 and P4 for the EEG recording and the wrist was selected as the FES rehabilitation site. EEG spectrum were compared between FES only and FES with game condition. The results showed that FES game significantly suppressed alpha rhythm in EEG compared to the FES only condition.

This paper describes the design of portable arrhythmia monitor and associated algorithm for automated diagnosis based-on microcomputer in the ambulatory ECG recording, analysis, and transmitting to a hospital host computer immediately through the telephone system. The device differs from Molter recorder in that it does not store normal ECG signals but captures and alarms the ECG during suspected abnormal periods and selected temporal epochs to a central hospital site. This porta file arrhythmia monitor makes use of a general purpose computer and software will be changed to meet the custom requirements of individual physicians and patients. At present it is very obvious that each cardiologist has his own method of analyzing ECG recordings and utilizes past experience more than the firm quantitative analysis of data.

Electrogastrography(EGG), the cutaneous recording of the myoelectrical activity of the stomach using surface electrodes, is attractive due to its non-invasiveness. We propose feasible methods to detect tile gastric contraction by vector analysis of the surface EGG signals obtained from three paired electrodes. The amplitude and direction of the calculated EGG vector were analyzed and compared with the gastric contraction signals such as the strain gauge signal from the gastric serosa in dog. From the vector analysis of the EGG signal, we found a typical change of the amplitude and direction of the EGG vector, which can indicate occurrences of the gastric contraction.

The holographic measurement techniques can be applied to various industrial fields such as automobile, airplane, construction, electronics, medical, mechanics and physics. The visualization of fluids is very important in aerodynamics, heat transfer and stress analysis. There are classically optical methods such as shadowgraph, schlieren method, and Mach-Zehnder interferometry for visualizing the fluid flow phenomena. But, it is difficult to understand the continuous state of fluids well in those methods. In this study, the real-time holographic interferometer with high-speed camera is applied to the flow visualization. In addition, collimated laser beam and rotating wedge are used for recording and formation of carrier fringes, respectively.

In Growth Hormone (GH) therapy, suboptimal adherence is a common problem, reaching up to 82%, and there is a need for interventions to improve adherence and to maximize patients' growth potential eventually. Current studies have demonstrated the association between the rate of non-adherence and reduced height velocity. In order to maximize patients' potential to grow, an auto-injecting/recording device, such as $easypod^{TM}$, may help improve adherence and optimize the treatment effects of GH therapy. The use of $easypod^{TM}$ has contributed to high adherence rates: 87.5% and 93% in Bozzola et al.'s study and the $Easypod^{TM}$ Connect Observational study (ECOS), respectively. Improvement of adherence by $easypod^{TM}$ may lead to higher growth rates of patients receiving GH therapy. Additionally, patients' positive acceptability of $easypod^{TM}$ suggests $easypod^{TM}$ is a preferred device by patients for better adherence.

The left ventricular relaxation rate is used as a golden standard which describes the left ventricular diastolic unction. So far, to get the rate of relaxation one should calculate the data after full recording, that is, off-line method. Therefore one cannot get the rate of relaxation in real-time while changing loading condition or infusing drug. But real time monitoring of the relaxation rate is necessary while changing loading condition or infusing drug to control the mechanics of heart and to get more information. We propose a new criterion to get the left ventricular relaxation rate and a real time algorithm. By comparison, it was turned out that our criterion outperforms others criterion.

In this paper, we developed the process for depth-probe type silicon microelectrode arrays. The process consists of four mask steps only. The steps are for defining sites, windows, and for shaping probe using plasma etch from above, and for shaping using wet etch from below, respectively. The probe thickness is controlled by dry etching, not by impurity diffusion. We used gold electrodes with a triple dielectric system consisting of oxide/nitride/oxide. The shank of the probe taper from 200um to tens of urn tip and has 30 um thickness.
