The whole blood inventory control model is developed, shown to provide an accurate representation of actual blood bank operations in Korea. The main difference of the blood bank situations between Korea and the United States is that about 50 percent of all bloods demanded, crossmatched, and held for a particular patient are eventually found not to be required for that patient in case of U.S. while in Korea the crossmatch test is not so significant and almost successful. Accordingly, the model in this paper is focused in seeking the minimum inventory level where neither shortage nor outdating bloods begin to occur, while the Jennings' model, developed in 1970 at MIT OR Center, is the inventory level somewhere between the inventory level 'band' where both shortage and outdating occur.

The Generalized Estimating Equations (GEE) approach is a widely used statistical method for analyzing longitudinal data and clustered data in clinical studies. In dentistry, due to multiple outcomes obtained from one patient, the outcomes produced from an individual patient are correlated with one another. This study focused on the basic ideas of GEE and introduced the types of covariance matrix and working correlation matrix. The quasi-likelihood information criterion (QIC) and quasi-likelihood information criterion approximation ($QIC_u$) were used to select the best working correlation matrix and the best fitting model for the correlated outcomes. The purpose of this study is to show a detailed process for the GEE analysis using SPSS software along with an orthodontic miniscrew example, and to help understand how to use GEE analysis in dental research.

As medical service industry is transformed into the market centered on consumers, medical service quality patients recognize is emphasized as the powerful means to ensure competitive advantage among hospitals in the fierce medical markets. Many researches have been done on the definition of medical service quality, developing a scale to measure it, patient satisfaction, hospital repurchase and oral transmission intention, but integrated studies have not been done sufficiently on the patient' cognitive emotional aspects. For these research purposes, based on service relation, service quality, physical surroundings, human services, corporate reputation, service value, emotional response, customer satisfaction and repurchase intention, this paper suggests a theoretical modeling composed of hypotheses on the relations of each theoretical variable. In addition, the moderating effect of service relationships is investigated based on the structural equation model.

Objectives The purpose of this study is to know the effect of Baekhogainsam-Tang on alopecia areata. Methods We decided the treatment principle through abdominal examinations and symptoms. We used herbal medicine (Baekhogainsam-Tang) to increase the roots of hair and hair. Results After the treatment, patients' hair condition had been improved (Hair loss patch diameter decreased from 2.5 cm to 0.5 cm). In addition, patient's physical symptoms were improved. Conclusions This case shows that herbal medicine, which focused on patient's physical symptom, is seemed to be effective in alopecia areata.

The senses that a doctor can feel is limited in MIS(Minimal Invasive Surgery) which guarantees the fast recovery of the patient and minimal incision for going in and out of instruments through the tissue of the patient. In particular, the surgical robotic teleoperation system developed recently serves with only the information of eyesight and auditory sense. Therefore force-reflection is the most demanded element of the senses in manipulating surgical instruments. In this paper, we designed the Master system and the 2 D.O.F grasper for the robotic teleoperation system(Slave) that has two force sensors on the grasper. Particularly, we focused on serve to master's handle with the contact force between tissue and the grasper of Slave.

It is practical nowadays to automate data recording in order to prevent loss and tampering of records. There are existing technologies that satisfy this needs and one of them is wireless sensor networks (WSN). Wireless body sensor networks (WBSN) are wireless networks and information-processing systems which are deployed to monitor medical condition of patients. In terms of performance, WBSNs are restricted by energy, and communication between nodes. In this paper, we focused in improving the performance of communication to achieve less energy consumption and to save power. The main idea of this paper is to prioritize nodes that exhibit a sudden change of vital signs that could put the patient at risk. Cluster head is the main focus of this study in order to be effective; its main role is to check the sent data of the patient that exceeds threshold then transfer to the sink node. The proposed scheme implemented added a time-based protocol to sleep/wakeup mechanism for the sensor nodes. We seek to achieve a low energy consumption and significant throughput in this study.

The purpose of this study was to determine the effects of associative drawing task in a Korean bilingual aphasic. The subject is a 41-year old male and lived and was educated in the United States for over 25 years(from the age of 14 through 39). His former occupation was a psychiatrist. He has had a massive lesion in the occipital lobe. This study focused on improving his spontaneous language performances by associative drawing task. The associative drawing task along with spontaneous speech is to help the subject's cognition. The ten target words in this treatment were familiar words and could be drawn easily. The results were that the associative drawing task was effective on improving the patient's drawing ability-writing ability in English only-and naming performance both in English and Korean. However, the patient's writing ability in Korean did not show any improvement.

In Korea, it is urgently required to develop the health care facilities and services for People with dementia. The progression of dementia is associated with a gradual decline in functional, cognitive, emotional, and social abilities. Therefore, architectural design for People elderly with dementia should be focused to maintain and preserve this abilities. This study aims to derive the design guidelines of the ward and patient roon unit planning to maintain this abilities in the health care facilities for People with dementia. For this, investigation and analysis through the case studies of domestic and foreign facilities and P.O.E of domestic facilities were performed.

Recently, the Korean medical system changed with diversification & specialization and the field of medical service is also specialized in these days. The medical space settings are usually designed for staff needs rather than for patient needs. but The purpose of this project was to identify the design elements for the patient-focused. Main keyword of this project is 'high touch' and basic design concept is 'a sense of stability/velocity'. This medical space is located in Sanbon, and it has an area of 171m$^2$. The material scheme in the interior design of medical space is an important factor for the hospital users. Painting, stainless steel, wood veneer, fabric and p-tile were used as interior finishing material.

The purpose of this study is to suggest reasonable composition and layout of a nurse station and attached spaces-which are central sector of patient caring in the inpatient department- in the view of funtional efficiency. The method of this study is examining other studies and case study of inpatient department in general hospitals. through this research we find out the plan type of inpatient department and layout of nurse station and attached spaces in the view of 'the efficiency of circulation' and 'the easiness of observation' . It is also found out that the nursing delivery system effects to the composition and layout of nurse station attached spaces. Therefore, the efficient design of inpatient department by this study can accomplish 'patient-focused' medical environment and aid to develop their health.
