Purpose: The purpose of this descriptive study was to investigate the pattern of physical restraints used in ICUs and to identify influencing factors of application and removal of restraints. Method: The subjects of this study were 90 restrained patients out of 215 patients over 6 years old who were admitted to 6 ICUs in SMC during a 2 weeks period. The data was collected through a questionnaire of characteristics, guidelines and nursing care of restraint uses. The data were analyzed by non-parametric statistic with the use of the SAS program. Results: The restraints were applied to 31.4% of subjects. Mean time of physical restraint was $36.76{\pm}55.7$ hours. There were significant difference with mean time and frequency according to duty shift. GCS, restless behavior and discomfort factors, medical devices, and life sustaining devices had significant relation with application of restraints. In addition, the mean time of restraints used were related significantly with GCS, restless behavior, and discomfort factors. Conclusion: The used of restraints were dependent on mainly the nurses' decision. Thus ICU nurses have to develop the guidelines to applying restraints and removal of restraints in regard to patients rights and ethics. Continuous monitoring and evaluation of application of the restraints is essential in professional nursing.

Purpose: The study was to develop psychoeducational intervention and identify its effect for symptom management of home cancer patient. Method: Study subjects were 24 patients in control group and 18 patients in experimental group. In experimental group, individualized psychoeducation was done after pretest and then continued to educate and consult through calling by telephone once a week for 4 weeks. The data were collected using several tools such as symptom distress by McCorkle(2000). Physical functioning, a part of Medical Outcome Study by Ware and Sherbouine(1992) and QOL- cancer patient version by Ferrell and Grant(1995) from 18th of Feb. to 30th of July. Data were analysed to ${\chi}^2$ test and t test using SAS VER8.12. Results: The mean score of symptom distress was 21.6 in experimental group and 24.2 in control group. Experimental group was shown lower score than control group. Physical functioning of experimental group was better as mean score 23.3 than 20.6 in control. Psychological wellbeing was 69.7 in experimental group and 66.1 in control group. Social wellbeing was 32.2 in experiment and 25.8 in control. Psychosocial wellbeing of experimental group was higher than control group. However there was no significant differernce between two groups among these variables. Conclusion: The psycho educational intervention was not made symptom mangement, physical functioning, and psycho social wellbeing improved but shown positive tendency. It is expected having a statistically significant finding if enlarged sample size and prolonged the intervention term in future. Therefore it is suggested psycho educational intervention study do repeatedly.

This research describes the construction of a site index equation and curves for Douglas-fir plantation (Pseudotsuga menziesii Mirb. Franco) in Nelson, New Zealand. The data sets of 146 Permanent Sample Plots (PSP) were used to build the model, and it was developed using the difference equation method. Parameter estimates were obtained using the non-linear routine of the SAS, PROC NLIN procedure. Of the models tested, a variant of the Schumacher polymorphic yield function showed the higher precision of fitting. About 95% of the observations used to fit the model could be predicted within ${\pm}1.2m$ of the actual values. Therefore, polymorphic family of site index curves, which reflect different shapes for the different site index classes, were derived from the Schumacher equation. It was found that the polymorphic site index equation was more accurate than the anamorphic equation in this study.

The purpose of this study was to investigate the effects of dietary behavior on the nutritional status of university students in Korea. A dietary intake survey of 603 university students (223 males and 380 females) was conducted using a 24-hour recall method. The resulting data on dietary behavior and nutrient intakes were analyzed by the SAS program package. The main results were as follows : 1) Most of the subjects were in their twenties and no obese cases were found. 2) Dietary intake data showed that, except for vitamin C in the female students, the average daily intakes of most nutrients did lot meet the Korean Recommended Dietary Allowances (RDA). The study also showed that most of the subjects, especially the female students, were concerned about having satisfactory physical appearances. Fat provided 25% of the daily energy intake, and this level was higher than the 20% recommended by the Korean Dietary Guidelines. In the female students, the iron intake from animal foods was lower than that from plant foods. 3) Male students were not very serious about healthy eating. However, the female group, who obtained a high score in dietary behavior, consumed more vegetables and had higher intakes of energy, protein, Ca, p, vitamin A, and vitamin C than the male group, even though they did not meet the Korean RDA in most nutrients. Energy intake from fats, as a percent of total energy intake, was lower than in the group of females who obtained higher stores in dietary behavior than the other groups. To sum up, the university students surveyed in this study were found to have the typical dietary behavior of young adults, such as frequent eating out and snacking. Female students were extremely conscious of their body images this can exert an important direct influence on their dietary intakes and health status. It is very important for university students to develop healthy lifestyles and desirable dietary behaviors, to best enable them to continue to lead a healthy lift: in their later years.

Market segmentation helps providers to find better marketing opportunities and allows foodservice managers to develop the right product for each target market. Therefore, this study, taking university faculty and staff as subject, is intended to diagnose the relative value of service quality attribute, on the basis service quality scenario of faculty foodservice; to suggest price for improving customer loyalty in market segments. A questionnaire was developed ar d mailed to 600 Yonsei university faculty and staffs. A total of 385 questionnaires were usable; resulting in a 58.7％ of faculty and a 69.7％ of staff response rate, respectively. Statistical data analysis was completed using the SAS/Win 6.12 for descriptive Analysis, ANOVA, principal factor analysis, cluster analysis, reliability test and discriminant analysis. The results of the study are as below. Eighteen questions were selected for measuring respondents' lifestyle by AIO method and the seven lifestyle factors derived from factor analysis and aggregated distinct 4 clusters. Service quality attributes of the scenario were determined with 'food quality', 'menu variety', 'atmosphere', 'fast service', and 'clean and sanitation'. 'Food quality', 'menu variety', 'atmosphere', 'fast service', and 'clean and sanitation', in decreasing order, were identified as improving customer loyalty. However, most faculty and staffs were satisfied with the present meal price. The result of this study indicates that the relative value of service quality was differed significantly among the various market segments. 'Food quality', 'menu variety', and 'atmosphere' were determined as major service quality attributes. Thus, customer loyalty could be increased by improving food taste and quality, atmosphere, and service delivery. (Korean J Community Nutrition 8(4) : 556 ∼565, 2003)

Periotest(Siemens, Germany) has been used to test mobility of the implants clinically, however the effects of target materials and connection methods on the PTVs(Periotest Values) have not been evaluated. Periotest has been regarded as a reliable and objective tool to test implant and natural teeth mobility clinically, however this instrument showed different PTVs under various test conditions. This in vitro study was designed to compare PTVs of different veneering materials and prosthodontic designs (single and bridge restorations). To compare the effects of veneering materials on PTVs, 1 mm thickness of five different testing materials (porcelain, type III gold alloy, pure titanium, composite resin, acrylic resin) were placed on the resin block. Three full length of 13 mm Mark II implant fixtures were embedded into autopolymerizing resin block to fabricate single and bridge restorations. To evaluate effects of the connection method in single restorations, PTVs of screw retained(UCLA type) and cementation type(Cera-One system) were compared. Finally, to test reliability of PTVs of the final restorations, screw retained three unit short span PFM bridges were fabricated on the standard and Estheti-Cone abutments. All testing components were tightened with torque controller and PTVs of all specimens were measured 15 times for statistical analysis with SAS program. Following conclusions were made within the limit of this in vitro study. 1. PTVs of type III gold alloy, grade II titanium, composite resin veneering materials showed no significant differences, however acrylic resin and porcelain showed significant differences (P<0.05). 2. Single tooth restorations showed consistent PTVs as long as proper torque force was applied. 3. PTVs of bridge type prostheses was inconsistent regardless of abutment types. 4. PTVs of the prostheses showed higher scores and standard deviations than those of abutments regardless types of connection (P<0.05).

Objectives : This study was conducted to evaluate the risk factors associated with cardiovascular disease. Methods : By the questionnaire, the informations of education level, monthly income, alcohol consumption and smoking habit were obtained. Height, weight and blood Pressure(BP) were measured by a trained nurse. The level of lasting blood sugar(FBS), total cholesterol, hight-density lipoprotein(HDL) cholesterol and triglyceride were tested by enzyne method about a group of 2888 males and 1696 females ages ever 20 who had never taken the medication for hypertension. Statistical analysis, ANOVA, stepwise multiple regression, correlation analysis were peformed using SAS package program. Results : There were significant differences among age groups in systolic and diastolic blood pressure, body mass index(BMI), FBS, triglyceride and cholesterol except HDL-cholesterol. The risk factors associated with systolic and diastolic BP significantly in male were BMI, age, alcohol intake, but in female BMI, age. Smoking habit had a significant negative correlation with BP in both sex. In the group of mild hypertension ($\geq140\;mmHg\;or\geq90\;mmHg$ defined by JNC-VI) and hypertension ($\geq160\;mmHg\;or\;\geq95\;mmHg$ defined by WHO), the percent of diabetes $(FBS\geq140\;mg/dl)$, hypercholesterolemia $(\geq240mg/dl)$, and hypertriglyceridemia $(\geq200\;mg/dl)$ were significantly higher compared with normal group in male and female. BMI, and alcohol consumption had a positive correlation with FBS, total cholesterol and triglyceride. Smoking had a positive correlation with cholesterol and triglyceride but negative correlation with HDL-cholesterol in male. The educational attainment had a negative correlation with BMI, FBS, total cholesterol and triglyceride in female. Conclusions : This study suggested that drinking, smoking, and BMI and lower educational level were associated with hypertension, hyperlipidemia and diabetes, but further evaluation was needed by prospective intervention study.
