  • This study was conducted to evaluation the quality of meals served in elementary school based on nutrient contents and food diversity . A questionnaire was mailed to school foodservice dietitians requesting one week menus for April and October . Menus served in 388 schools from each province and from major cities in Korea were analyzed. Mean nutrient contents per meal of persons served, and food expenses per meal. Mean percentages of energy from fat was 20.2% , and was significantly l different by foodservice system. When nutrient contents were converted to amount per 1, 000kcal, all were higher than that calculated from RDA except calcium, iron, and Vitamin A. Most of these were not significantly different according to area, foodservice system, the number of persons served, and food expense per meal. Compared to 1/3 of RDA for children , many meals provided lower amounts of energy, Vit A, VitB2, and Ca. More than half of the meals provided less iron than 1/3 RDA for 10-12 years girls. Using the highest values of RDA for the elementary school age group as evaluation, criteria nutrient adequacy ratios(NAR) were lowest for Ca(0.61), Vit A(0.57), and iron(0.77). The mean adequacy ratio(MAR) was 0.86. Mean numbers of food items and dishes per meal were 15.3 and 5.1 , respectively. 66.3% of the meals provided three food groups of grain, meat, and vegetable. Except for the number of different food items served per meal, the aspect of food diversity was similar to that of nutrient contents. There was significant positive correlation between mean number of different food items served per meal and nutrient content . In summary , schools in small cities and rural areas than those in large cities, schools adapting commissary or joint management than those or density. Also the more food groups served per meal, the higher the nutrient content per meal . In summary , schools in small cities and rural areas than those in large cities, schools adapting commissary or joint management than those adapting conventional foodservice system, schools serving smaller number of persons, and schools with higher food expenses provided higher energy contents and food diversity.

  • This study investigated the trends in the number of applicants and mean score and applicants' responses on the test items of 'science inquiry' of the College Scholastic Ability Test(CSAT) implemented for 3 years$(1999\;{\sim}2001)$. The results of this study were as follows: The percentage of applicants of science track for 1995 CSAT were 43.13%, but reduced to 29.5% for 2001 CSAT. And unlike other tracks, the percentage of male applicants, ranking above average, of science track was 65.58%, which is about twofold of female applicants(34.42%). The mean score of 'Science inquiry' was 58.6 in 1999, and 69.5 in 2001. And the score of the applicants, ranking above average, of humanity and social science course and science course, were 85.8 and 90.7 respectfully in 2001 CSAT. These high mean scores were caused by the policy of "easy CSAT" so called. Most of test items were developed to have difficulty 60-79% or above 80%. This easy CSAT provoked intense dispute about the discriminating power of CSAT. The mean score of male applicants was higher than that of female. But the difference decreases every year. Applicants were generally very good at solving tests focusing on process skills only but poor at solving tests related to physics or calling for two or more science concepts. Thus special measures to cope with the decrease in applicants, especially female applicants, for science track should be provided. To increase discriminating power of CSAT, it is recommended to develop test items with wider range of difficulty and to reduce test items which are focussing process skills and can be solved without any special science concepts. And special consideration should be given to teaching the content area with poor achievement and high actual difficulty compared to the expected.

  • A reliability acceptance sampling plan (RASP) consists of a set of life test procedures and rules for eitheraccepting or rejecting a collection of items based on the sampled lifetime data. Most of the existing RASPs areconcerned with the case where test items are available at the same time. However, as in the early stage ofproduct development, it may be difficult to secure test items at the same time. In such a case, it is inevitable toconduct a life test using sequentially supplied samples.In this paper, it is assumed that test items are sequentially supplied, the lifetimes of test items follow anexponential disthbution, failures are monitored continuously, arrival times of test items are known, and thenumber of test items at each arrival time is given. Under these assumptions, RASPs are developed by deter-mining the test completion time and the critical value for the maximum likelihood estimator of the mean lifetimesuch that the producer and consumer risks are satisfied. Then, the developed plans are compared to thetraditional Type-I censored RASPs in terms of the test completion time. Computational results indicate that thetest completion time of the developed RASP is shorter than that of the traditional Type-I censored plan in mostcases considered. It is also found that the superiority of the developed RASP becomes more prominent as theinter-arrival times of test items increase and/or the total number of test items gets larger.

  • The aim of this research is to contribute to enhancing the competitiveness of automotive parts suppliers while departing from the dependent relationship structure, by developing and interpreting factors that affect sale, which are financial achievements, in a practical way. The research data covered 200 companies from 2013-2017. The study hypothesis was verified by dividing the hypothesis into Model1 with control variables only and Model2 with control variables in independent variables. As a result of hypothesis testing, regarding sales, only capital size showed to have an effect in Model1, while in Model2, asset size, number of employees and joint ventures with foreign companies did but the other remaining factors did not. In particular, the results showed that an increase in financial performance required 'Economies of scale', and that companies that concentrated on a small number of items, diversified products into four or more items, or owned two to four suppliers, reaped positive results in financial performance. Therefore, in addition to the selection and concentration of corporate management for production items and account management, applying strategies, like the inter-company M&A, consortiums and co-branded strategies to achieve 'Economy of scale', would highly enhance the financial performance of automotive parts suppliers.

  • In the history of fashion, the category of knitted items was traditionally associated with ordinary clothing products like undergarments and socks. However, in a mere century Chanel has changed that idea by bringing into fashion consciousness items such as sports sweaters, jerseys, and suits, and so it has been necessary to upgrade this notion. As the needs of the times and new inventions have an inseparable relationship, knit fashion was also born with a close relationship with the zeitgeist of the time - the feminine movement, the rise of sports fashion and the world war - adapting itself up to the present time through continuous changes. Most brands are elevating knit from a mere decoration into a collection piece in a large number of collections every year. The number of brands that cannot exist without knit is increasing, such as Sonia Rykiel, Missoni, and so on. This essay is written with the purpose to study the birth, growth and future potential of knit items. The first stage concentrates on the age of knit's appearance (1910s-1930s). Contingent upon the collection of further data, this essay will be continued through the second stage (the 1960s - 1970s) and the third stage (after the 1980s).

  • The statistical process control charts are very extensively used for monitoring of process mean, deviation, defect rate or reject rate. In this paper we consider a control chart to monitor the process reject rate in the high yield process, which is based on the observed cumulative probability of the number of items inspected until r defective items are observed. We first propose selection of the optimal value of r in the CPC-r charts, and also consider the usefulness of the chart in high yield process such as semiconductor or TFT-LCD manufacturing process.

  • The problem of clustering stock-keeping-units to assign storage locations is treated. Firstly, a construction heuristic algorithm is developed to cluster items considering demand dependencies(correlated assignment) for the case that the maximum number or the maximum volume(weight) of items per tray is constrained by the capacity of tray. Secondly, inventory-related cost as well as material handling cost is considered to determine the space requirement and the storage location of each item simultaneously.

  • Purpose : The purpose of this study was to develop a tool to assess the need for hospice care in families of patients with cancer. Method : Research design was a methodological study. The tool was developed in 3 stages : first, preliminary items were developed based on a questionnaire about the needs for hospice care that was given to 8 families of patients with cancer; second, a panel of specialists reduced the number of preliminary items using 2 validity tests on the contents. Finally, reliability and validity were tested by a sample of 98 families who have a patient with cancer from April 2003 to July 2004. Result: Cronbach's alpha coefficient for internal consistency was .94 for the final total 22 items. Using the factor analysis, 4 factors with eigenvalue of more than 1.0 were extracted and these factors explained 65% of the total variance. The four factors were labeled as 'control of terminal physical problems', 'emotional care', 'spiritual care for preparing for death', and 'family support'. The final items of the tool developed on the need of hospice care consisted of 22 items. Conclusion : The instrument, for accessing the need for hospice care in families of patients with cancer, developed in this study was identified as a tool with a high degree of reliability and validity. In this sense, this tool can be effectively utilized for implementing and improving hospice care for patients with terminal cancer.
