  • In this study, a part of high school science instructional materials is evaluated by Instructional Quality Profile(IQP) based on the Merrill's Component Display Theory(CDT). The CDT is based on the Gagne assumption of different conditions of learning for different outcomes. The IQP enables the user to check both the consistency and adequacy of existing cognitive instruction. The IQP can be used to predict student performance, and also to design and develop new insturctional materials. The instructional components are classified according to 5 task levels; An Use-Generalities on Newly Encountered Examples(UGeg), A Remember-Paraphrased -Generalities (RpG), A Remember-Verbatim-Generalities (RvG), A Remember-Paraphrased -Examples (Rpeg), A Remember-Verbatim-Examples(Rveg). And the instructional presentations are classified according to 4 levels: Explain Generalities(EG), Explain examples(Eeg), Inquiry Generalities(IG), Inquiry examples(Ieg). The instructional presentations are determined by instructional components of a related test item, and indexes of the presentation adequacy are calculated by the instructional presentations. The indexes of this study(0.17 - 0.44) were very low and it indicates that the instructional presentations were not adequate to the instructional components of the related text item.

  • The purpose of this study was to examine the feasibility and validity of the Application of Cognitive Function Scale as developed by Lidz and Jepsen (1997). Data were collected from 4 to 5-years-old children. The analysis for item adequacy indicated that the passing rate increases according to age. Futhermore the analysis for test adequacy indicated that internal consistency reliability was .85 in the pre-test and .80 of post-test in terms of the cognitive function scale, and .90 of pre-test and .93 in the post-test in relation to the behavior observation scale. In conclusion, our analysis of the ACFS shows sufficiently high scores in terms of both validity and reliability, so as to indicate that this test is an appropriate way to measure the cognitive function and non-intellective function of young Korean children.

  • The objectives of the study were to provide the basis for nutrition education for consumers so that they could select nutritious and balanced fast foods and to promote menu items for fast foods franchisers by addressing nutrition and health. Nine franchisers (3 hamburger, 3 noodles and 3 chicken) were surveyed in terms of their nutritional concern for product development, and 360 consumers were interviewed at 36 fast food chains to assess their perceptions of nutrient adequacy of fast foods. The taste of foods was being addressed most when developing menu items in surveyed franchisers but nutrition and variety of menu were being considered least. Hamburger chain franchisers showed greater nutritional concerns in promoting menu items than noodles or chicken chain restaurants. Their nutritional concerns include utilization of nutritional information as promotion of menu item, providing nutrition information of menu item to consumers, and evaluating nutritional balance of their menu items. As a result of INQ evaluation of combined fast food selected by consumers for a meal, the desirable case of both nutritious and adequate in calorie was 14.7%, nutritious but lack in calorie was 44,1%, adequate in calorie was 24.5%, and undernutritious and lack in calories was 21.6%, 45.7% of snack selected by consumers had more calories than needed for a meal.

  • This study was conducted to develop and validate the Sugar Intake Reduction Test (SIRT) for young children, and included eating behaviors, attitude, and nutritional knowledge about sugars. A draft version of the SIRT was developed after literature review. The final draft of the SIRT was established after two pilot tests of 5 year old children and an expert group's review, and is comprised of a one on one test between an investigator and a child using picture tools. It contained of 20 questions which included 3 components: eating behaviors (5 items), preference for sugar sweetened food (10 items), and nutritional knowledge about sugars (5 items). The final SIRT was conducted on 181 children 5 (n=100) to 6 (n=81) years old, to examine its item and test adequacies. The passing rate of most items significantly increased with increasing age, and most of the item discrimination also differed significantly between the below and upper score groups. The content validity was given a high score by professionals (mean score 3.9 out of 4). Reliability of all the items in the SIRT was high (Cronbach's ${\alpha}=0.82$). Moreover, the total component and the sub-component scores of the SIRT correlated significantly. Our results indicate that the SIRT is a valid tool to measure sugar intake reduction in young children aged 5~6 years.

  • The develop a simple screening test for identifying Korean elderly at risk of undernutrition, the data of the health-related habits, dietary behaviors and nutrient intakes of the elderly in Chongju were analyzed. Two risk indicators, mean adequacy ratio (MAR) and the respondents perceived health, were used to detect the undernutrition risk of the elderly. In order to select a list of questions for the test, factors a affecting nutritional status and items investigated in previous nutrition surveys of the elderly were considered, and 21 questions were primarily selected. A multiple regression and stepwise regression analysis were used to take out the weak predictors of poor nutrient intake, and to give item weights to the strong predictors, and a list of 17 questions was finally adopted. To determine the cut-point of the test score, sensitivity, and positive predictive values were calculated. The Simple Screening Test developed in this study is a brief, easily scored tool to predict poor nutrient intake and the perceived health status of the elderly. The test may provide a basis of further comprehensive nutritional assessment or intervention planning, if necessary, for those who are diagnosed ad "high risk". The test, however, needs to be independently validated by other groups of individuals.dividuals.

  • Purpose: The purpose of this study was to test the reliability and the validity of the Practice Environment Scale of Nursing Work Index (PES-NWI) scale when applied to Korean psychiatric nurses working in the psychiatric hospital in Korea. Methods: Data from 224 psychiatric nurses working in the 6 psychiatric hospitals in Korea were analyzed using Cronbach's ${\alpha}$, item total correlation, and exploratory factor analysis. Results: The Cronbach's ${\alpha}$ for the 27 items from the PES-NWI were .93, and the item total correlation coefficients ranged from .38 to .64. Six factors which explained 61.2 of variance in the perception of practice environment, emerged; nurse professional role and development, nurse manager ability, leadership, and support of nurses, staffing and resource adequacy, nursing foundation for quality of care, collegial nurse-physician relations, co-worker's ability and qualification. Five derived factors reconstructed, and two factors were renamed. Conclusion: Findings demonstrate that not all but 27 items from PES-NWI is a reliable and valid scale when applied to Korean psychiatric nurses working in Korea. Also findings indicate that Korean psychiatric nurses perceive practice environment differently than American nurses but have some point of similarities with Asian nurses working in the United States.

  • The purpose of this study was to investigate satisfaction and preference for current military meal service and food behaviors and food habits of some military personnel in Chunchen and Wonju of the Kwangwon area. The results are as follows. In the anthropometric survey, average height of the subjects was 175.03 $\pm$ 5.30 cm, average weight was 69.15 $\pm$ 7.74 kg. As a result of surveying satisfaction in the current food service, an item high in satisfaction was adequacy of serving hours, whereas an item of low satisfaction was diversity of menu. The item of food service improvement needs of the subjects were in order more variety of menu, nutrition, preference, sanitation, cooking method. As a result of surveying eating behavior of the subjects, most items were high medium response. They preferred soju and relish and also they liked the bokkum cooking method. As a result of surveying food habits of the subjects, items of good habits were regularity of meals, marginal meals, diversity of food intake, dairy and dairy products, avoiding too exciting meals and natural food diet; whereas, items of bad habits were fast food intake, alcohol, smoking, carbonated and caffeine beverages, skipping breakfast. snacks, fatty food intake, yellow or green vegetable intake and fruit and seaweed intake. Following is the result of a survey on the preference of meals by cooking method serving the current military meal service. They liked one-dish meals such as Bokkeumbap, Bibimbap, Tteokguk, whereas, they disliked curryrice, Jajangbap. In case of soup, they liked soup made from meat better than vegetable soup or soup made with fish. Also they liked pot stem better than soup. Generally they liked meals containing meat in most cooking methods. These results suggest that continuous and practical nutrition education to change food habits in military life are necessary to Prevent chronic disease with increasing age.
