The purposes of this study were to analyze the work patterns of selected hospital foodservices by Work Sampling methodology, and to investigate the relationship among operational factors affecting productivity. The hospitals were classified into 3 groups by the percentage of patient meals, and the percentage of special patient diet, and the menu items of patients meals. The groups clustered were characterized by productivity. Work Sampling methodology was utilized to analyze the work patterns of hospitals with selected 3 hospitals to investigate the productivity the productivity and labor times used in each work functions. Productivity index analyzed by Work Sampling were 10.36 min/meal, 10.95 min/meal, and 12.19 min/meal, respectively X, Y, Z hospital. Z hospital was significantly different from time used in direct work function and delay. Direct work function time was the highest, delay the lowest in Z hospital. The relation between the results of Work Sampling and the productivities of 3 groups showed not by delay but direct work function in the classification used in this study.

The purposes of this study were to assess hospital foodservice quality and to identify causes of quality problems and improvement strategies. Based on the review of literature, hospital foodservice quality was defined and the Hospital Foodservice Quality model was presented. The study was conducted in two steps. In Step 1, nutritional standards specified on diet manuals and nutrients of planned menus, served meals, and consumed meals for regular, diabetic, and low-sodium diets were assessed in three general hospitals. Quality problems were found in all three hospitals since patients consumed less than their nutritional requirements. Considering the effects of four gaps in the Hospital Foodservice Quality model, Gaps 3 and 4 were selected as critical control points (CCPs) for hospital foodservice quality management. In Step 2, the causes of the gaps and improvement strategies at CCPs were labeled as "quality hazards" and "corrective actions", respectively and were identified using a case study. At Gap 3, inaccurate forecasting and a lack of control during production were identified as quality hazards and corrective actions proposed were establishing an accurate forecasting system, improving standardized recipes, emphasizing the use of standardized recipes, and conducting employee training. At Gap 4, quality hazards were menus of low preferences, inconsistency of menu quality, a lack of menu variety, improper food temperatures, and patients' lack of understanding of their nutritional requirements. To reduce Gap 4, the dietary departments should conduct patient surveys on menu preferences on a regular basis, develop new menus, especially for therapeutic diets, maintain food temperatures during distribution, provide more choices, conduct meal rounds, and provide nutrition education and counseling. The Hospital Foodservice Quality Model was a useful tool for identifying causes of the foodservice quality problems and improvement strategies from a holistic point of view.

Purpose: The aim of this study was to examine the utilization of and satisfaction with the smart bedside station (SBS) system among users in a hospital. Methods: A cross-sectional descriptive design was used. The participants were 190 patients, 186 family caregivers, and 154 nurses in a hospital. Results: Around 78.1% of patients or family caregivers used the SBS system at least once during their hospital stay. The commonly used items on the SBS system menu were "lab findings", "hospital cost", "today's medication", and the "alarm message". Satisfaction with the SBS system of patients and family caregivers were significantly higher than those of nurses (F=39.88, p<.001). Conclusion: A patient-centered SBS system was a useful system that could increase patient satisfaction and comfort. More specific and technical service contents reflecting the current healthcare system should be added.

Laboratory information system (LIS) is a key tool to manage laboratory data in clinical pathology. Our department has developed an information system for routine hematology using down-sized computer system. We have used an IBM 486 compatible PC with 16MB main memory, 210 MB hard disk drive, 9 RS-232C port and 24 pin dot printer. The operating system and database management system were SCO UNIX and SCO foxbase, respectively. For program development, we used Xbase language provided by SCO foxbase. The C language was used for interface purpose. To make the system use friendly, pull-down menu was used. The system connected to our hospital information system via application program interface (API), so the information related to patient and request details is automatically transmitted to our computer. Our system interfaced with fwd complete blood count analyzers(Sysmex NE-8000 and Coulter STKS) for unidirectional data tansmission from analyzer to computer. The authors suggests that this system based on down-sized computer could provide a progressive approach to total LIS based on local area network, and the implemented system could serve as a model for other hospital's LIS for routine hematology.

The purpose of this study was to investigate the compliance and need for diet therapy among diabetics and their caregivers. A total of 625 respondents participated in this survey. Appropriate management for long-term blood glucose control and difficult-to-manage cases appeared to be diet therapy, physical activity, medical treatment and folk remedies, in that order. The most important educational avenues for diet therapy were books, magazines and TV, Most respondents were educated in diet therapy within a year after diagnosis and had practiced diet therapy for over four years. The most common diet therapy Practices were food selection and Quantity control. Of the specific problems in practicing diet therapy, time and labor, taste, and meal planning appeared to be equally difficult factors. The prevailing diet therapy skills were controlling food amounts at breakfast and supper, and selecting food for lunch and refreshments. Respondents practicing both skills were about 20% of the participants; this shows the need to improve the current situation. The nutrients most frequently considered in diet therapy practice were simple sugars (sugar and sweet goods) , total fats and cholesterol. Since the perception of the role of dietary fiber among respondents was very low, nutrition education about the importance of dietary fiber and food sources of dietary fiber was needed. Diabetics seemed to be concerned about diabetic menus. Three difficult problems in planning diabetic menus were daily menu planning, patient's preferences, and the calculation of calories. As a means of nutrition counseling, they preferred interviews. The higher the educational status and the lower the age, the higher the preference was for internet or PC counseling. Therefore, it is necessary to develop nutrition educational programs so that diabetics can obtain practical knowledge of diet therapy. Furthermore, it is also necessary to develop additional means of informing diabetics about menu planning, while still considering Korean dietary behavior.

MRI는 1970년을 시작으로 자장 세기와 수신 채널 수, 촬영시간의 단축 등으로 많은 발전을 해 오고 있으며, 병원 또한 각종 전산 시스템과 무선 네트워크의 발전으로 인해 각종 진료 영상장비로부터 디지털 영상을 획득, 저장 및 관리하게 되었다. 하지만, 국내 대학들은 고가의 실습장비와 유지비로 인하여 자체에서는 실습을 하지 못하고 있으며 임상 실습에 의존하고 있다. 이에 윈도우즈 운영체제의 PC상에서 MR 환자의 검사 프로그램을 개발하여 학생들이 많이 다루어 봄으로써 임상에서 근무하기 전 많은 도움을 주고자 하였다. MRI Simulator의 Relational Database 설계는 각 기능과 자료의 특성에 따라 7개의 Table로 구성하였으며, 환자정보 설계는 임상에서의 환자등록 방법을 기준으로 각 단계별 기능을 분류 하였다. 또, 검사를 위한 기본 정보 설정을 가정하여 각각의 설정 값 및 그 내용을 분류 하였다. 실행 단계별 메뉴는 한 눈에 볼 수 있도록 왼편에 배열을 하였다. 환자 등록은 이름, 성별, 고유번호, 생년월일, 몸무게 등 기초정보를 입력하고, 환자의 자세와 검사 방향을 설정하였다. 또, 검사부위와 Pulse Sequence을 나열하고, 선택하도록 분류하였다. 그리고 Protocol 이름과 부가 인자들를 입력할 수 있도록 하였다. 최종 화면은 검사 영상과 환자 정보, 검사 조건 등을 확인할 수 있도록 설계하였다. 이 프로그램을 통해 환자정보의 입력과 검사조건의 변경을 학습해봄으로써 이론과 실습을 통한 용어의 이해에 많은 도움을 주어 실제 임상근무에서 배우는 시간을 단축시킬 수 있다.
