Purpose: The study aimedto provide basic data to improve the quality of home healthcare nursing services by evaluating quality of care in representative nationwide sites. Method: The current quality of home care service in 104 nationwide sites was evaluated in terms of structures, processes, and outcomes based on published standards of the Joint Commission on Accreditation of healthcare Organizations. Results: The mean score for three dimensions of quality of home care service was as follows in descending order: structures (77.6), outcomes (60.4), and processes (38.7). Additionally, by specific item compared level of quality of home care servicein each site, the highest score was 97.3 and the lowest score was 42.3 out of 100, with a mean score of 74.7. Conclusions: These findings provide a base for establishing the quality management system and to develop a tool for evaluating the quality of home healthcare nursing. The result should be continuous management and improvement of home healthcare nursing quality.

The purpose of this study was to investigate dietary intake and to evaluate patient satisfaction toward the quality of hospital foodservice. Questionnaires were distributed to 203 hospitalized patients in 3 hospitals having 300 beds. The intake rates for served amounts of rice, side dishes, and soup were 72.5%, 68.2%, and 62.6%, respectively. The main reasons for left-overs were 'no appetite' (25.8%) and 'not salty enough' (19.9%). The rate of patients eating outside food was about 33.5%. The average score for quality satisfaction of meal characteristics was 3.34 ${\pm}$ 0.61, and the average score for quality satisfaction of sanitation and service characteristics was 3.58 ${\pm}$ 0.61. 'Seasoning' showed the lowest score and 'temperature' showed the highest score for quality satisfaction of meal characteristics. In the quality satisfaction of sanitation and services, 'explanation of meals' showed the lowest score and 'exactness of meal times' showed the highest score. The patients hospitalized for 10 days showed significantly lower average scores than those hospitalized over 60 days for quality satisfaction of meal characteristics. The patients with 'little appetite' and 'regular appetite' showed significantly lower average scores than those with 'much appetite' for the quality satisfaction of meal, sanitation, and service characteristics. The patients who 'rarely had leftovers' showed significantly higher average scores than those who 'always had leftovers' and 'often had leftovers' for quality satisfaction of meal characteristics. Meal characteristic scores were significantly correlated with age (r = 0.216), length of admission (r = 0.310), appetite (r = 0.251), leftovers (r = 0.233), and intake of soup (r = 0.205). Also, sanitation and service characteristics scores were significantly correlated with age (r = 0.327), education (r = -0.202), length of admission (r = 0.168), and appetite (r = 0.155). Thus, it would seem to be desirable that hospital foodservices improve the taste and seasoning of meals and provide appropriate nutrition education and counseling in mid-sized hospitals.

The design of this study was a cross sectional correlational survey. The subjects were 220 out and in-cancer patients in 5 general hospitals in Pusan. The data were collected from July 2 to August 1, 2001. The instruments were the Percieved social support scale(16 items, 5 point scale) had developed by Tae(1986), Hope scale(12 items, 4point scale) developed by Nowotny(1989) and Quality of life scale(31 items, 10 point scale) developed by Tae et al.(2000). The data was analyzed by the SPSS/PC+ program using frequency & percentage, item mean & standard deviation, t-test, ANOVA & Scheffe test, Pearson's correlation coefficient. The results of this study was as follows: 1) The item mean score of quality of life was $6.05{\pm}1.16$ (range 0-10). The highest score of subarea of the quality of life was the spiritual wellbeing area ($7.09{\pm}1.63$) and the lowest score was social wellbeing area ($5.53{\pm}1.65$). The mean score of perceived social support was $52.65{\pm}10.32$ (최저 1, 최고 80). The mean score of family support was $32.71{\pm}6.66$ (range 1-40) and the mean score of medical team support was $19.93{\pm}5.95$ (range 1-40). The mean score of Hope was $37.02{\pm}5.64$ (range 1-48). 2) There were statistically significant difference in the score of quality of life according to the life effect of religion(F=3.97, p=0.00), treatment method(F=2.94, p=0.01), area of diagnosis(F= 3.48, p=0.01), stage of disease (F=13.74, p=0.00). 3) There was significant correlation between perceived social support(r=0.44, p=0.000 ; family support ; r=0.334, p=0.000, medical support; r=0.395, p=0.000), hope(r=0.563, p=0.000) and quality of life. In conclusion, there was a significant relationship among perceived social support, hope and quality of life. Therefore perceived social support, hope intervention programs should be developed to improve the quality of life in cancer patients.

The data of dietary intakes were obtained using food frequency questionnaires which were collected from 151 postmenopausal women in urban area. Diet quality was assessed by INQ(index of nutritional quality), MAR(mean adequacy ratio), DDS(dietary diversity score), DVS(dietrary variety score), DQI(diet quality index). The results are summarized as follows. The mean age of the subjects was 59.9 years old. The means of height, weight, and BMI were 154.7cm, 57.2kg and 23.9 respectively. The subjects who did not exercise regularly were 70.9% and those who excercised at least once a week were 29.1%. The subjects who had regular meal time were 69.5% and those who ate breakfast regularly were 72.6%. More than 2/3 of subjects had regular eating behavior. Overall dict quality was significantly(p < 0.05) associated with INQ, MAR, DDS, DQI. However, there was no significant association between income level and diet quality. In conclusion, it would be beneficial to provide nutritional education included dietary diversity, dietary variety, dietary guideline, and adequate flood amount, to prevent chronic degenerative disease and maintain healthful life in the postmenopausal women.

Purpose: The purpose of this study was to explore the psychosocial responses and quality of life (QOL) among Amyotrophic Lateral Sclerosis (ALS) patients and their caregivers in South Korea. Methods: A cross-sectional design was used. Purposive sample of 15 ALS patients and their 14 caregivers were recruited via Korean Amyotrophic Lateral Sclerosis Association (KALSA) website. Demographic characteristics, hopelessness, quality of life, physical function, and caregiver burden were measured. Results: The mean period after being diagnosed with ALS was 57.73 months. The mean score of amyotrophic lateral sclerosis functional rating scale and quality of life was 21.33 (SD=11.97) and 5.70 (SD=1.23) respectively. The mean score of hopelessness was 11.87 (SD=4.72). The caregivers' mean score of McGill quality of life was 4.29 (SD=1.46), and the mean score of McGill quality of life-single item scale was 4.29 (SD=2.02). Conclusion: Since the cause of ALS has not been identified and cure is yet to be discovered, supportive care should be provided for not only quality of life but hope of patients. The findings may be used to develop knowledge based nursing intervention for patients diagnosed with ALS and their caregivers.

Data analysts explore collections of data to search for valuable information using various techniques and tricks. Garbage in, garbage out is a well-recognized idiom that emphasizes the importance of the quality of data in data analysis. It is therefore crucial to validate the data quality in the early stage of data analysis, and an effective method of evaluating the quality of data is hence required. In this paper, a method to visually characterize the quality of data using the notion of a saliency score is introduced. The saliency score is a measure comprising five indexes that captures certain aspects of data quality. Some experiment results are presented to show the applicability of proposed method.

Many domestic studies related to service quality are performed but the study on computing Service Quality Score is not yet activated. Because Service quality measurement plays an important role in assessing service performance and diagnosing service problems, it is very important that service quality is measured exactly. Therefore this study offered realistic approach method for computing Service Quality Score by using T.L. Saaty's Analytic Hierarchy Process technique. That is, Service Quality Score of this study is computed by using customer's priority(weights) for five dimensions(Tangible, Reliability, Assurance, Responsiveness, Empathy). This method is more realistic than the existing method computed by an arithmetical average of dimension's variables.
