The purpose of this study was to identify the factors affecting family functioning of stroke patients. A descriptive survey research was conducted in which 65 stroke patients and their primary caregivers were conveniently sampled. Data were collected from July to September, 1998 through interviewing using a structured questionnare. The measuring instruments used were Barthel Index by Mahoney and Barthel(15 items), Quality of Relationship Scale by Archbold and Stewart(15 Items), Role Stress of Caregiver Scale by Yang(14 items), Situational Definition Scale by Lee(9 items), Family Hardiness Index by McCubbin, McCubbin. and Thompson(20 items), and Family Adaptability Cohesion Evaluation Scale(FACES-III) by Olson, Portner, and Lavee(20 items). The obtained data were analyzed using percentage, t-test, ANOVA, Duncan test, and Pearson coefficients correlation by SAS/PC program. The results were as follows; 1. Role Stress of Caregiver was not severe and Quality of Relationship was moderate. The level of Situational Definition of primary caregivers was not high but Family Hardiness and Family Functioning were rather high. 2. The following relationships between research variables and demographic characteristics of the primary caregivers of stroke patients were significantly different; occupation of caregiver between Quality of Relationship, occupation of caregiver between Situational Definition, family type between Role Stress, caregiving duration between Family Hardiness, caregiving duration between Family Functioning, and hospitalization days between Family Functioning. 3. The correlations between research variables were as follows; There was positively correlated between patient's ADL and Quality of Relationship. The relationship of the patient's ADL between Role Stress was negatively correlated. Quality of Relationship between Situational Definition, Family Hardiness, and Family Functioning were significantly correlated. The correlation of Situational Definition between Family Hardiness, and Situational Definition between Family Functioning were very high. As a result of these findings, Quality of Relationship, Role Stress, Situational Definition. and Family Hardiness were useful variables for identifying Family Functioning of stroke patients. It is important for the rehabilitation nurse to be knowledgeable about family functioning of stroke patients to promote rehabilitation process.

Objectives : This study was conducted to investigate the systematic error, such as seasonal change or inadequate food items, in a food frequency questionnaire administered to workers in a Nuclear Power Plant, Korea. Methods : We performed three repeat-tests with 28 subjects on May 13, July 8 and Dec 16, 1992. Our food frequency questionnaire (FFQ) comprised 84 foods organized into 7 food-groups, and was composed of the items of usual intake frequency (8 categories) and the amount per intake (3 or 4 categories) over the previous year. We compared the means of intake frequency and the frequency of the portion-size according to each season using Repeated Measures ANOVA and Pearson's chisquare test with Fisher's exact test. Results : We found the significant seasonal changes of several food items in intake frequency measurement. These items were typical seasonal foods such as mandarin orange, plum and green vegetables, while the single questions consisted of inadequate food items such as thick beef or similar soup and various kimchi products. Significant seasonal changes in portion-size were found in only two items: cooked rice-brown and fresh frozen fishes. Conclusions : The systematic errors observed could caused loss of validity in the FFQ. Consideration should be given for seasonal variation in FFQ survey and methodological concerns are needed to improve the quality for measuring usual diet pattern.

The goal of the National Assessment of Educational Achievement(NAEA) 2001 was to affirm the accountability of school education, to scientifically manage and elevate the quality of education at the national level, and to articulate the final design of the NAEA. It was implemented on June 28th of the year 2001. The assessment frame for NAEA includes the achievement standards, the assessment standards, the instruction for the item development, and the grading policy for mathematics subject. Most of items are multiple-choice types, but the performance-based items should be at least thirty percent of the total items, also 30% in case of mathematics. Approximately 1% of students among entire population of the Grades 6 were randomly selected. Therefore, the finally sampled examines were 8023 at Grade 6. The result of the analysis of the NAEA revealed that Grade 6 students was labelled as ‘average’ level in general (Number and Operation: average, Geometric figures: average, Patterns and Functions: excellent, Measurements: average, Letters and Expressions: average, Probability and Statistics: average). The most characteristic finding was that except for Grade 6(its average is 69.92), most secondary students obtained low test scores and its average of each grade is below 50 out of 100. Especially, the scores on the performance-based items were by and large very low. This finding implies that Korean students are not familiar with the kind of test items which requires expression of ideas and feelings and they are rather familiar with the multiple-choice items. Another interesting finding was that the students in small towns and remote areas showed significantly low scores in all four skills compared with Seoul, metropolitan cities and medium and small cities. This may be attributed from the fact that the remote areas do not have equal learning environment with regard to social and cultural experience, supply of various teaching materials, extracurricular lessons which are directly related to teaching and learning. These findings may be utilized as a reliable resource fur improving curriculum and teaching and learning in Mathematics.

We investigated clothing consumers' perception of benefits and risks on internet shopping and tried to identify the perceptual differences according to presence of real experiences of internet shopping, intention to buy clothings using the internet, clothing items, and demographic variables. A total of 441 people aged of twenties and thirties were surveyed for analysis. The mean values, standard deviation, Student's t-test, paired t-test, ANOVA and multiple range test were used for statistical analysis. The results of this study included: 1. Clothing consumers perceived the internet shopping as a convenient, time-saving method, and an easy way to compare clothing items, but not a cheap tool. The most highly perceived risk was inability to identify the size of clothing item, followed by shortage of stock, delivery problem, color, textiles, after-service, and exposure of personal informations in a decreasing order. 2. Those who had real experiences of internet shopping or who had intention to use it tended to perceive more benefits and less risks on the internet shopping. 3. Perception of risks and benefits differed according to the clothing items and demographic variables.

The purpose of this study is to develop questionnaire items for the Pilot Aptitude Personality Test(PAPT) which can predict the flight training achievement through personality and personal characteristics. To do this, we investigated the personality traits required to successfully conduct flight training for 30 flight instructors as a subject. The results were as follows: motivation, concentration, concentration, situational awareness, and concentration. Based on this, preliminary 300-item questionnaire was prepared by combining the existing studies related to pilot aptitude. Survey was conducted using preliminary questionnaire for 152 student pilots as a subject. As a result of the correlation analysis between the results of the questionnaire and the flight training, 16 questions were derived. Finally, factor analysis showed that the final 14 questionnaire items were confirmed. The internal concept of an item is categorized as personality, perception, and motivation. This study suggests that the pilot aptitude should be viewed from an extended point of view by analyzing individual characteristics and pilot aptitude in relation to flight training achievement.

In Korea association of health promotion(KHAP) there are fourteen laboratories in branch offices and one laboratory in headquarter office. To standardize the reference ranges of all laboratories of KAHP, they have been newly calculated from the laboratory data perfomed during the previous yearsby statistical metod annually for the period of 2000 through2003 so far. The referance ranges of total 56 test items were assigned. Among these there were eight test items that needed referance ranges by age groups and nine test items that needed reference rages by gender. The age grouping was into six groups : baby (0-3y), children(4-12y), adolescent(13-18y), adult(19-64y), younger elderly(19-64y), older elderly(over 80y) with references of statics in Medical Informatics and WHO classification. All the data collected were statistically analyzed with SAS 6.04 for Gaussian distribution that had been repeated two or three times after trimming out the the tests showed Gaussian distribution. Subsequently, Thereference ranges were defined in the rage from the point of lower 2.5% to the point of higher 97.5%. And in case the lower range could be "0", the reference ranges were defined in the range of 0 to 95%. Fifteen laboratoried troughout Korea of KAHP currently have standarzed reference rages of the tests that they perform. This means the patient data and reference values an be exchangeable among laboratories of KHAP.Annual revise of such reference rages can eventually lead to the level of those representing a standard of the national reference ranges.

Purpose: This study was done to develop the self-report Mother-Preschool Child Interaction Scale (MPIS) for mothers of preschool children. Methods: The scale was based on items derived from literature review and in-depth interviews. A methodological study was used to check reliability and validity and participants were 334 mothers of preschool children enrolled in kindergarten or nursery. Data were analyzed using principal component factor analysis for construct validity, t-test for contrasted group validity, Pearson correlation for criterion related validity and test-retest reliability and Cronbach's ${\alpha}$ for reliability. Results: In the final MPIS 34 items identified through factor analysis were included, 6 constructs were derived, and explanatory power was 64.2%. Items on the MPIS were verified through correlation with the interaction observation scale of Kim & Mahoney and MPIS. Results were significant as mothers in the normal group exhibited MPIS scores that were significantly higher than those of mothers in the depressed group. Reliability of MPIS was .96 and test-retest reliability was .92. Conclusion: MPIS has the advantage of being easy to use, economical, and useful. Consequently, it is expected to be used as a screening tool for promptly and simply identifying the mother-preschool child interaction in diverse nursing practice and research.
