Current medical information management systems use man's hands or wired network for information transmission. It is difficult to check the situation information of the patient in real time. Moreover, it is also cumbersome to transfer the information. In this paper, we obtain the bio-signal in real time through wireless LAN, and store the carrer information of the patient at the management server in the hospital. We studied about development of system which provide the management server in the hospital. We studied about development of system which provide a career information service through PDA to the doctor as well as patients.

In today's technological development of human society more and more influence on the lives of biological organisms different electromagnetic radiation. Therefore, the study and analysis of the mechanisms of their effects is an urgent task. The purpose of research - the study of the primary mechanisms of interaction of photons of optical radiation with the structures of biological objects, using the laws of quantum mechanics and biophysics. Photobiological basis of the mechanism of action of EMR optical range is the energy absorption of light quanta (photons) by atoms and molecules of biological structures (law Grotgus-Draper), which resulted in the formation of electronically excited states of these molecules with the transfer of photon energy (internal photoeffect). This is accompanied by electrolytic dissociation and ionization of biological molecules. The degree of manifestation of photobiological effects in the body depends on the intensity of the optical radiation, which is inversely proportional to the square of the distance from the source to the irradiated surface. Accordingly, in practice, determine not the intensity and irradiation dose at a certain distance from the source of exposure by the exposure time.

Purpose: The purpose of this study was to identify the factors associated with the discontinuation of patient controlled analgesia (PCA) after surgery. Methods: The data of 1,092 adult patients that were over 20 years of age and underwent PCA after surgery in the Gachon University Hospital from May 1 to June 30, 2017, were collected through the patients' Electronic Medical Record (EMR). The collected data was analyzed via the use of the Chi-test, t-test and multivariate logistic regression analysis using SPSS 18.0 program. Results: The postoperative PCA discontinuation rate was 26.1%. It was associated with various symptoms, such as those of nausea, dizziness, and headache. The PCA discontinuation was also related with female (odds ratio, OR= 1.75; confidence interval, CI= 1.09-2.82), nausea (OR= 105.27; CI= 61.03-181.58), total intravenous anesthesia (TIVA) of the thyroidectomy (OR= 10.43; CI= 5.01-21.70). Conclusion: It is necessary to provide additional medication and nursing interventions to reduce nausea, which is the symptom associated with PCA discontinuation, especially in the operation of female subjects and thyroidectomy under TIVA. That is, those who are at a high risk for PCA discontinuation should be able to administer additional antiemetics or reduce non medication nursing interventions.

Purpose: This study tries to propose the dimensions and area related to patient bed and surroundings in ICU considering nurses' observation and medical care. Methods: Literature survey, 11 Case studies, some Interviews with nurses and measuring of medical equipments' dimension in ICU have been mobilized in order to deepen the ICU bed area standards. Results: 0.3m clearance between head wall and patient bed is necessary for emergency cases. The minimum distance at the foot of the bed should not be less than 0.9m for EMR cart and medical tray. The clear floor area of one bed and surroundings in open ward is $10.2m^2(3m{\times}3.4m)$. In a single-bed patient room, the minimum clear floor area is $16.0m^2(4m{\times}4m)$. Considering the control of cross infection in ICU, Single bed patient room is recommended. Implications: The result of this study can be applied to the design of ICU and legislation of ICU standard.

The paper is to build recommendation systems leveraging Deep Learning and Big Data platform, Spark to predict item ratings of the Amazon e-commerce site. Recommendation system in e-commerce has become extremely popular in recent years and it is very important for both customers and sellers in daily life. It means providing the users with products and services they are interested in. Therecommendation systems need users' previous shopping activities and digital footprints to make best recommendation purpose for next item shopping. We developed the recommendation models in Amazon AWS Cloud services to predict the users' ratings for the items with the massive data set of Amazon customer reviews. We also present Big Data architecture to afford the large scale data set for storing and computation. And, we adopted deep learning for machine learning community as it is known that it has higher accuracy for the massive data set. In the end, a comparative conclusion in terms of the accuracy as well as the performance is illustrated with the Deep Learning architecture with Spark ML and the traditional Big Data architecture, Spark ML alone.

Objectives : This study aims to propose a processing method for dosage units of medicinal materials and the database schema to manage formula data in Korean medicine ontology. Methods : All dosage units of medicinal materials are collected from the seven textbooks that contain formula data of Korea medicine ontology. Dosages are converted to Arabic numerals and units that are frequently used are converted to representative units. Database schema is designed for processing and managing the formulas and medicinal materials with dosage units. Results : Seven representative units are selected out of 77 units. They will be used in the addition or subtraction of medicinal materials in a formula support system. The remaining units will be made available for references. Conclusions : EMR or chart programs used in clinical hospitals contain formula data that is already standardized. However, the formula data in Korean medicine literature and textbook is not refined, so it is necessary to process the dosages and units of medicinal materials to use in the formula support system. This result is a processing method to utilize the formula data of Korean medicine textbooks and it will be implemented this method in the established formula support system in the future.
