Objectives: With the increase in the number of people who are marginalized in receiving medical services, the role of Seoul National University Hospital as a public hospital is being emphasized. However, many patients are either experiencing delays in receiving medical services or simply being left out as a result of the inaccessibility to the department of social work on part of both the patients and the medical staff. Methods: In order to increase consultation from other departments and the accessibility to the department of social work for the socially marginalized group through early consultation from other departments, the following steps were taken. First, an orientation program for novice medical residents led by clinical social worker was introduced/implemented. Second, posters and brochures on various financial aids programs were produced and distributed. Third, a system of early screening was built/constructed, and once a week rounds and early screening meeting were executed/carried out. Result: The department of social work's rate of consultation from other departments increased by 4.4% compared to last year, while it showed 61% increase for those wards that had an early screening meeting. In addition, the average time of consultation from other departments was reduced by 3.1 days, securing sufficient amount of time for clinical social work services, both in terms of quality and quantity. Conclusion: It is believed that the various promotional activities, along with the strengthening of accessibility to clinical social work services and early consultation on part of social disadvantaged/marginalized group, would undoubtedly help provide quality services to patients and increase their level of satisfaction. In this way, the wards can effectively reduce the number of unnecessary hospital stay days while the hospital can prevent the accumulation of outstanding bills/fees as well as contribute to the publicness of hospitals. The promotion of clinical social work programs in various ways are crucial to ensuring the satisfaction of patients and hospital staff.

In Korea, the majority of hospital dietitians expend most of their time performing food management related activities, and only a few carry out nutrition care activities in full-time. This study was designed to measure productivity of the clinical nutrition team and assess the role of clinical dietitians in the only 2200-bed teaching hospital in Korea. Six full-time clinical dietitians collected time data for four weeks according to the nutrition care activities outlined. Three clinical dietitians assigned to 7 units recorded how often physicians implemented their recommendations for two months. Two kinds of survey questionaire were developed and sent to the patients and the health care team. The followings are a summary of the results. 1. The clinical nutrition team of 6 full-time dietitians expended 75% of their time performing patient care activities, 20% in non-patient care activities and 5% in delay and transit. 2. Each clinical dietitian assigned to the units carried out 56 patient care activities on daily basis. 3. The average time required for the clinical nutrition services was 60.2 minutes for outpatient counseling, 89 minutes for inpatient counseling, 72.5 minutes for nutrition management, 95 minutes for malnutrition consult and 121 minutes for dysphagia diet management. 4. Physicians' implementation of clinical dietitians' recommendations was 98.5%. 5. Most physicians and nurses viewed the clinical dietitians on the units assertive, contributing to the quality improvement of medical services, and helpful to the patients as well as the health care team. 6. Most patients viewed the clinical dietitians on the units considerate, attentive and helpful. Based on these results, it is suggested that (1) daily meal round and nutrition care monitoring are effective tools for nutrition intervention in the hospital setting. (2) unit assignment of clinical dietitians enhances the patients' satisfaction in the nutrition services provided as well as the perceptions of health care team on clinical dietitian's expertise.

Purpose: The purpose of this study was to propose a revised Clinical Ladder System(CLS) Model for nurses based on the evaluation of clinical competence and professional activities of nurses working in general hospitals. Methods: Data were collected between September 10 and October 30, 2017. Participants were 50 head nurses from 10 general hospitals with over 400 beds located in Seoul City and Gyeonggi Province. Each head nurse evaluated clinical competence, qualifications, and professional activities of 5 staff nurses at each of the 5 levels of CLS in her unit. The total number of the nurses evaluated was 245. Data were analyzed with descriptive statistics and t-test, one-way ANOVA, and $Scheff{\acute{e}}$. Results: Over 80% of the nurses were university graduates. As the CLS levels increased, clinical competence, qualifications, and professional activities also increased significantly. Education material development and quality improvement activities were carried out by nurses from level 2, research and evidence based practice activities were carried out from level 3, and nurses at level 4 or 5 participated in most of the professional activities as leaders. Conclusion: In order to retain excellent nurses in general hospitals, recognizing and rewarding nurses according to the revised model of the CLS are recommended.

The academic journal is a very important means for science communication, and it is critical for academic development. Most of Korean academic journals are not doing their fundamental roles because of the researchers' perception about their quality. A fundamental thing for Korean academic Journals to contribute effectively to science communication would be the effective evaluation on the journal. The purpose of this study is to develop an evaluation model for Korean academic Journals. This model will be effective for quality measurement, manifestation of the strength and weakness, and for the improvement of journal qualify. It was developed through analysis on evaluation activities of two institutions, and through interviews and surveys on Korean researchers.

We investigate the outage probability in terms of QoS (quality of service) in indoor PLC network. We consider various kinds of appliances for realistic indoor PLC network. For estimation of the outage probability, we calculate the time-varying channel responses considering the loading conditions based on regular human activities and include the additive noise. We calculate the outage probability for each terminal and investigate relationship between the outage probability and the channel length, and transmit powers. Our results suggest that the outage probability is increased when the channel length becomes longer because more appliances affect the amount of reduced channel capacity and is not improved distinctly for very high and low outage threshold by increasing the transmit power. However, we can see outage probability improvement for 30% outage threshold case by increasing the transmit power.

In modern society, people live in an environment with artificial or natural noise. Especially, the sound that corresponds to the artificial noise makes the noise itself and affects each other because many people live and work in the city. Sounds are generated by the activities and causes of various people, such as construction sites, aircraft, production machinery, or road traffic. These sounds are essential elements in human life and are recognized and judged by human auditory organs. Noise is a sound that you do not want to hear by subjective evaluation, and it is a loud sound that gives hearing damage or a sound that causes physical and mental harm. In this study, we introduce the method of stimulating the human hearing by finger vibration and explain the advantages of the proposed method in various kinds of a noise environment. And how to improve the sound quality to improve efficiency. In this paper, we propose a method to prevent the loss of hearing loss and the transmission of sound information based on proper signal to noise ratio when using portable IT equipment in various noise environments.

Background : A pressure sore was defined as any skin lesion caused by unrelieved pressure and resulting in damage to underlying tissue. The health care institutions in the United States were reported the incident rate of pressure sores ranging from 6 to 14 %. Intensive Care Unit needed highest quality of care has been found over 40% incidence rate of pressure sore. Also, Annual expenditures for the care of pressure sores in patients in the United States have been estimated to be $7.5 billion; furthermore, 50 percent more nursing time is required to care for patients with pressure sore in comparison to the time needed to implement preventive measures against pressure sore formation. However, In Korea, there were little reliable reports, or researches, about incidence rates of pressure sore in health care institution including intensive care unit and about the integrated approach like CQI action team for risk assessment, prevention and treatment of pressure ulcers. Therefore, this study was to develop pressure sore risk assessment tool and the protocol for prevention of pressure sore formation through CQI action team activities, to monitor incident rate of pressure sore and the length of sore formation for patients at high risk, and to approximately estimate nursing time for sore dressing during research period as the effect of CQI action team. Method : CQI action team in intensive care unit, launched since early 1996, reviewed the literature for the standardized risk assessment tool, developed the pressure sore assessment tool based on the Braden Scale, tested its validity, compared on statistics including incidence rate of pressure sore for patients at high risk. Throughout these activities, CQI action team was developed the protocol, called as St. Marys hospital Intensive Care Unit Pressure Sore Protocol, shifted the emphasis from wound treatment to wound prevention. After applied the protocol to patients at high risk, the incident rate and the period of prevention against pressure development were tested with those for patients who received care before implementation of protocol by Chi-square and Kaplan-Meier Method of Survival Analysis. Result : The CQI action team found that these was significant difference of in incidence rate of pressure sores between patients at high risk (control group) who received care before implementation of protocol and those (experimental group) who received it after implementation of protocol (p<.05). 25% possibility of pressure sore formation was shown for the patients with 6th hospital day in ICU in control group. In experimental group, the patients with 10th hospital day had 10% possibility of pressure sore. Therefore, there was significant difference(p<.05) in survival rate between two groups. Also, nursing time for dressing on pressure sore in experimental group was decreased as much as 50% of it in control group. Conclusion : The collaborative team effort led to reduced incidence, increased the length of prevention against pressure sore, and declined nursing care times for sore dressing. However, there have had several suggestions for future study. The preventive care system for pressure sore should be applied to patients at moderate, or low risk throughout continuous CQI team activities based on Bed Sore Indicator Fact Sheet. Hospital-wide supports, such as incentives, would be offered to participants for keeping strong commitment to CQI team. Also, Quality Information System monitoring incidents and estimating cost of poor quality, like workload (full time equivalence) or financial loss, regularly in a hospital has to be developed first for supporting CQI team activities as well as empowering hospital-wide QI implementation. Being several limitations, this study would be one of the report cards for the CQI team activities in intensive care unit of an acute hospital and a trial of quality improvement of health care in Korea.
