Purpose: This study aimed to dosimetrically compare the technique of three-dimensional conformal radiotherapy (3D CRT), which is a traditional prophylactic cranial irradiation method, and the intensity-modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT) techniques used in the last few decades with the dynamic conformal arc therapy (DCAT) technique. Methods: The 3D CRT, VMAT, IMRT, and DCAT plans were prepared with 25 Gy in 10 fractions in a Monaco planning system. The target volume and the critical organ doses were compared. A comparison of the body V₂, V₅, and V₁₀ doses, monitor unit (MU), and beam on-time values was also performed. Results: In planned target volume of the brain (PTV_Brain), the highest D99 dose value (P<0.001) and the most homogeneous (P=0.049) dose distribution according to the heterogeneity index were obtained using the VMAT technique. In contrast, the lowest values were obtained using the 3D CRT technique in the body V₂, V₅, and V₁₀ doses. The MU values were the lowest when DCAT (P=0.001) was used. These values were 0.34% (P=0.256) lower with the 3D CRT technique, 66% (P=0.001) lower with IMRT, and 72% (P=0.001) lower with VMAT. The beam on-time values were the lowest with the 3D CRT planning (P<0.001), 3.8% (P=0.008) lower than DCAT, 65% (P=0.001) lower than VMAT planning, and 76% (P=0.001) lower than IMRT planning. Conclusions: Without sacrificing the homogeneous dose distribution and the critical organ doses in IMRTs, three to four times less treatment time, less low-dose volume, less leakage radiation, and less radiation scattering could be achieved when the DCAT technique is used similar to conventional methods. In short, DCAT, which is applicable in small target volumes, can also be successfully planned in large target volumes, such as the whole-brain.

Korea has entered the aged society, with those aged over 65 years accounting for 14~20% of its population. Interest in the quality of life, nutrition, and health of the elderly is increasing. Since the energy intake of the elderly is lower than the estimated required amount, nutrient intake ratio of the elderly is related to mastication. Yanggaeng is a high-energy food made from agar, sugar, and red bean paste. Since it has a soft texture, it is highly utilized as a snack for the elderly who have inconvenience in mastication. Pinus koraiensis needle is known to possess antioxidant and antibacterial effects. The purpose of this study was to develop a functional snack added with Pinus koraiensis needle extract powder known to possess anti-inflammatory, anti-cancer, and antibacterial effects for the elderly that would be easy for them to chew. In this study, yanggaeng was manufactured with 0%, 2%, 4%, 6%, or 8% of Pinus koraiensis needle extract powder, white sediment, and agar. In the experiment, moisture contents, color values texture characteristics, antioxidant activities, and sensory preference results were evaluated. Moisture content was the highest in the group added 6% of the extract powder. It was the lowest in the group added 8% of the extract powder, showing a significant (p < 0.001) difference between the two. Hardness, cohesiveness, and springiness of texture characteristics were decreased significantly (p < 0.001) while the adhesiveness and chewiness of texture characteristics were increased significantly (p < 0.001) as the amount of addition increased. Regarding antioxidative activity measurements, levels of polyphenols were the highest (p < 0.001) in the group added with 8% of the extract powder. DPPH and ABTS radical scavenging activities were increased as the amount of addition increased (p < 0.001). Overall sensory preference was the highest for the 2% addition group. It decreased as the amount of addition increased (p < 0.001). Results of this study indicate that Pinus koraiensis needle extract powder with antioxidant and antibacterial effects can be used to manufacture yanggaeng to make functional snacks with improved quality characteristics for the elderly.

The purpose of this research is to provide the data base for the activation of Quality Improvement operation through investigating the status of Quality Improvement operation, and finding out factors influencing on the goal-orientation of QI performers in the medical centers of more than one hundred beds where are practicing Quality Improvement operation. In order to reach the purpose, document study was carried out grounded on the proceeding researches and formulated statistical data in relation with the status of Quality Improvement performers, and proof study was carried out through questionnaire survey. The subjects of the survey were the Quality Improvement performers working in seventy three medical centers in Pusan-Gyeongnam, Daegu-Gyeongbuk, and Ulsan. Among eighty three Quality Improvement performers, fifty, five were questionnaire surveyed, on the result of which Reliability Analysis, Factor Analysis, and Multiple Regression Analysis were made, using statistical program. The the results of the proof analysis on this research are as follows. First, in the factors influencing the devoting to goal pursuit of QI performers, organization-goal contribution(0.44) had significant positive effects, while organization conflict(-0.25) had significant negative effects. In other words, the higher the organization-goal contribution was, the higher the devoting to goal pursuit was, while the less the organization conflict was, the higher the devoting to goal pursuit was, which was statistically significant.(p<0.05). Second, in the aspect of goal performance types of QI performers, the process-centered type showed high level of the devoting to goal pursuit, which was statistically significant.(p<0.05). Third, in the aspect of QI performance degree, the higher the devoting to goal pursuit was, the higher the QI performance degree was, which was statistically significant.(p<0.05). In addition, the performers who perceived their workplaces organic structure showed much higher QI performance degree, which statistically significant.(p<0.05). Generalizing the results of this research, it is possible to offer a few suggestions as follows. First, as the competition among the medical centers is more severe recently owing to medical center evaluation system, medical centers are practicing various Quality Improvement operation in all of medical services such as clinical performance and management performance, to reach the purpose of both cost-cutting and medical quality improvement. Thus in order to practice Quality Improvement operation more efficiently in medical centers, it is essential to nuke use of problem-solving methods and statistical members. This as the willingness of chief executives and positive attitude and recognition of organization members. This requires the installation of divisions in charge and disposition of persons in charge, not to speak of persistent training of Quality Improvement. Second, the divisions in charge of QI carry out Quality Improvement operation at the medical center level, and take the role of generalizing and adjusting QI performances of various departments. Owing to this role, the division in charge of QI is considered indispensable organization in the QI operation of medical centers along with medical QI committee, while it contributes to the government's goal of reducing quality level gaps among medical centers. Therefore it is necessary for government and QI organizations to give institutional support and resources for the sake of QI operation of medical centers, besides to supply systematic trainning and informations to the divisions and persons in charge of QI. Third, it is certain that disposition of persons in charge should be determined in view of the scale and the scope of QI operation in medical centers.

Nursing standards determine the type and extent of services that are delivered to the patients and define quality care and communicate the institution's expectations of care. Thus, taking the standard of care and incorporating it into a welldefined indicator of excellent patient care becomes one of the first activities in setting up the nursing service's quality assurance process. The purpose of this study was to determine the impact of using a nursing care standards for the quality of nursing care in gastrectomy patients. The subjects were composed of fourty-two under going gastrectomy patients with stomach cancer in general surgery nursing care unit of K University Hospital in Pusan. The data was collected from January 3 to April 13,1996. The subjects were divided into a control group - those admitted from Jan.3 to Feb.12 and an experimental group those admitted from Feb.18 to April 13. The instruments used for this study were a nursing care standards in gastrectomy patients developed by the investigator and an evaluation tool for the quality of nursing care in abdominal surgery patients developed by Byoung-Sook Lee in 1995. The data was analized by means of chi-square test, t-test and Cronbach-alpha test with the SAS System. The result was as follows : The hypothesis, that scores of the quality of nursing care in the experimental group would be higher than that of the control group. was supported(t=-6.12, p=0.00). The detailed results of each standards of evaluation tool were as follows : The mean score of the experimental group was significantly higher than that of the control group in audit standard 1:'Collection of basic data of the patients', (t=-3.76, p=0.00). The mean score of the experimental group was significantly higher than that of the control group in audit standard 2 : 'Defining nursing diagnoses(or nursing problems)', (t= (-), p= (-) ). The mean score of the experimental group was significantly higher than that of the control group in audit standard 3:'Estabilishment of nursing care plan according to nursing diagnoses(or nursing problems)',(t= (-), p= (-) ). The mean score of the experimental group was significantly higher than that of the control group in audit stndard 4:'Implimentation of nursing care plan', (t=-2.38, p=0.01). The mean score of the experimental group was significantly higher than that of the control group in audit standard 8 : 'Increase of the knowledge of health related to surgery',(t=-2.40, p=0.01). No significant differences between the mean scores of the experimental group and that of the control group in audit standard 5 : 'Recover and maintain of the physical function', audit standard 6:'Prevention of the post-operative complication', audit standard 7 : 'Decrease of discomfort caused by operation', and audit standard 9 : 'Patient satisfaction in nursing care' were found. The standards of evaluation tool were devided into two dimension. One was process dimension which contains four standards(audit standard 1 to 4), the other was outcome dimension which contains five standards(audit standard 5 to 9). The mean score of the experimental group was significantly higher than that of the control group in process dimension (t=-12.30, p=0.00), but no significant difference between the mean scores of the experimental group and that of the control group in outcome dimension was found. From these results, it is concluded that using a nursing care standards in gastrectomy patients promotes quality of nursing care and nursing care standards of various fields are necessary for effective nursing care.

Korea is to open its medical markets to foreign hospitals starting in the year 2006 regardless of our will(DDA, Doha Development Agenda). To accurately understand the characteristics of Korean medical users, their detailed and various needs, their attitudes toward the opening of Korean medical markets, and factors affecting these users in choosing foreign medical service providers would be first step needs to be taken by the Korean medical facilities that need to survive and develope through the fiercely competitive era coming with the opening of Korean medical markets to foreign medical service providers and would be very important in hospital management. The subjects of this study were 500 patients randomly selected from the outpatients who visited one of university hospitals in Seoul on the 14th-16th days of April 2003, and conducted a self-completion questionnaire. The answers of 463 respondents among the selected patients(93% of a responding rate)were analyzed through the Excel and statistics programs. The attitudes on the opening of the medical markets were shown in agreement 56.5%(247 persons), disagreement 6.9%(30 persons), and no idea 36.6%(160 persons). In consideration of only the answers as agreement and disagreement exclusive of the answer as no idea, 89.2% of the respondents agreed to the opening of the medical markets while 10.8% objected to the opening. The approval rate was higher with the higher education and income levels. Moreover, The approval rate for the opening of the medical markets was relatively high regardless of the satisfaction in the medical service, and the most important reason of the agreement was the guarantee of the patients(national)option. The main reason of the disagreement was high medical fee(50.5%), and the other reasons showing low rates were outflow of the domestic fund to the foreign countries(13.6%), damage of medical influences on the public(11.4%), lack of competition of the domestic medical industry(9.1%)and so on. As for the factors of selecting the foreign hospitals in the opening of the medical markets, the patients considered the authority(competency)of doctors firstly, and the other principal factors were worldwide fame and reliance, specific explanation of doctors, modernized medical instruments, convenient consultation procedure, etc. The patients agreed to the opening of the medical markets at a high rate regardless of the satisfaction in the medical service, and the most principal reason of the agreement was the guarantee of the patients(national)option for the medical care. Connected with the factors to select the hospitals, the approval reasons for the opening of the medical markets were the authority(competency)of the doctors as the first one, and then fame and tradition, reliance, overall diagnosis and modernized medical instruments, doctors specific explanation, and so on. However, these factors are actually associated with the Quality of the medical care, and consequently the approval reasons for the opening of the medical markets are connected with the security of the medical care. Accordingly, the guarantee of the patients(national)option answered as the main reason of the agreement can be also understood as the awareness of the right to have a variety of options for the security of the medical quality.
