Aircraft fuel indicator is a device to indicate the amount of fuel remained during flight, where accurate and consistent operation of the indicator should be maintained. Previously the Korean Utility Helicopter fuel indicator sporadically displayed abnormal sign by "8888" during flight, jeopardizing flight safety. Inappropriate EMI/EMC performance was detected during trouble shooting process. The cause of the abnormal display was found to be resulted from unstable power induced by electro-magnetic disturbance and CAN communication error. The aircraft fuel indicator design was improved and the design compatibility was verified to avoid abnormal display.

In case a firm proceeds with TQC the activity of QCC, one of the activities concerned with TQC, is made first of all. There fore, in consideration that TQC could not be successful with the activity of QCC being unsuccessful a firm underlines activating QCC and makes considerable support of the educational discipline. However, as for the data of TQC having been introduced in domestic country no data related to construction industry have been found, all of them being concerned with manufacturing industry and it has happened that some firms of the construction industry make the negative reaction to the activity of QCC. So some of firms including our one have prepared and published their own texts and made them available by utilizing the translated Japanese data which were attained through Japanese construction firms. It is thought that a problem has been caused by the above-stated. While Japanese firms have made R & D of the features concerning to the most basic QCC activity for themselves, Korean ones have just followed and taken advantage of those originated by Japanese without being conscious of the basic idea, and this has caused the consequent failing of QCC activity. In other word, the emphasis of the results only rather than process has brought about the unsuccessful QCC activity.

Purpose: The Study of vaccination for infants and children business in Primary Health Care Posts from 1980 to 2009. Method: look for national essential vaccination look for the change of vaccination by the times in Primary Health Care Posts and the rate of vaccination for infants and children by a administrative report statistics survey of a vaccine delivery system of Public health care institutions investigation about assistance details of vaccination cost in order to raise the rate of vaccination for infants and children. Results: In 1980s, there are many infants and children management object, but now there are rapidly decreasing infants and children management subject of a Primary Health Care Post because of rural exodus phenomenon of 1990's and a low birthrate of 2000's. Currently, the infants and children that registed, and managed to a Primary Health Care Post is most multi-cultural families. A multi-cultural family assistance program is provided these infants and children to the objects. Conclusions: Infant vaccination execution in Primary Health Care Posts showed to high vaccination rate because the prevention of vaccination delay or omission of the interior child who raised geographical accessibility to object sons nowadays it difficult to management of transportation of vaccine and storage management for a little shroud objects limited and management of inoculation business in quality. A main problem is as follows. There are a little vaccine transportation, trouble of proper temperature maintenance of a storage process, and having a lot of vaccine abolition as a little objects, educational training shortage of health care practitioner regarding to execute an inoculation. Therefore, vaccination business needs measures for management in quality in Primary Health Care Posts.

The curriculum of programming education including algorithm has been recognized as a very important subject to many students majoring in natural sciences and engineering including electronic engineering and computer related departments. However, many students have had difficulties with it due to its characteristics; as a consequence, they have been in trouble taking upper-level subjects. Flow chart is a diagram that expresses logical stages necessary to solve certain problems and has been widely used to have an understanding of the flow of algorithm. The practice-oriented education of algorithm and programming would be very important to assist the understanding of operation processes. Furthermore, it has been desperately required to the necessity of auxiliary programs that could enhance an understanding of the concept of algorithm and program execution process. This study was aimed to design and embody the learning system of programming languages using basic algorithms so as for students to easily learn basic algorithm among the entire programming curriculum.

In recent, many consumers visit the online shopping malls or price comparison sites to collect the information on the product category that they are interested in. However, the volumes of the data provided by such web sites are often too enormous, and significant number of consumers have trouble in making purchase decision based on the plethora of products and sellers. In this context, modern online shopping agents need to process the retrieved information in more intelligent way before providing them to the users. This paper proposes a novel approach for identifying the main price ranges hidden in a single product category. To this end, the price of an item in the category is represented as a row vector and k-means clustering analysis is applied to the price vectors to produce the clusters that consists of the product items with similar price vectors. Then, the main price ranges of the product category can be identified from the result of clustering analysis. In general, the price is one of the most important factors in the consumers' purchase decision, and the identified main price ranges will be helpful for the online shoppers to find appropriate items effectively.

When enjoying sports activities with friends or others, sportswear has symbolic meanings to express and expect self-concept. Sports players sometimes have trouble when they feel embarrassed by their low skills or care about other people too much. Therefore, researchers tried to find out which feature of sports players affects dependence on brand sportswear along with the effect of wearing conspicuous sportswear on wearer when sports players have a conflict based on Solomon's symbolic interactionism. We proposed that role knowledge and attention to social comparison information (ATSCI) influenced people to depend on and use brand sportswear that influences a reflexive evaluation. Finally, we suggested that a changed self-concept would exert influence commitment to sports. A quantitative study was conducted employing an online survey of 121 people by convenient sampling. In this process, Google Docs was to create the online survey and to collect responses by participants. In data processing, via SPSS 21.0 version for Windows, exploratory factor analysis, Cronbach's ${\alpha}$, ANOVA, t-test, discriminant and regression analysis were conducted to study the relationship between variables. The finding provided evidence that low role knowledge and high ATSCI create high dependence on brand sportswear and influence people to buy sportswear. When people bought and wore a brand sportswear, they evaluated themselves as professional sports players who were more committed to sports. This study confirmed that brand sportswear was useful for sport players to change self-evaluation and enjoy sports.

This study was carried out to investigate the vacuum drying characteristics of 50mm- and 75mm- thick tree disks of some domestic softwoods for substituting the conventional hardwoods as the materials for wood crafts. Though the elapsed drying times from green to in-use moisture content(MC) were largely shortened by vacuum drying, the tree disks treated by EWS couldn't be dried to in-use MC, and so sapwood stains also were occurred severely. We suggest EWS treatment is undesirable for the species with very high sapwood portion or vacuum drying with hot water circulation heating system. Heart checks were slight, but sapwood checks, which have never been trouble in drying process of tree disks, were severe. For the reasonable explanation it is suggested MC differences between sapwood and heartwood were large and most of tree disks had already no barks before drying test. Ginkgo was vacuum-dried with very slight drying defects such as heart checks, sapwood checks. V-cracks and sapwood stains. In Korean red pine and pitch pine V-cracks were severely occurred. And it was found the special feature that most of these defected tree disks contained several V-cracks within one tree disk. It can be considered as the causes that the region of sapwood was defected by the several checks at the early drying stage because of the steep MC gradient along the radial direction, and then at the later drying stage the drying stresses due to differential shrinkage were concentrated on these brittle spots.
