This study is to evaluate the morality of teenagers with regard to features of justice. On the basis of the findings, an online morality level test system is designed and implemented to help students understand themselves better and to increase moral maturity through this self-test method based on Kohlberg's Morality Development Level. The main purpose of this study is to help students test and evaluate their morality, and it will be contributed to slough off egocentrism and to orient a relationship based on a mutual respect by using the embodied system. If this system can be applied successfully, an effective improvement on students' further education guidance may be gained because the test and its results are made in the system simultaneously. Also this easy and fast test system can attain much more economical effects than a written test.

The aims of the study were to analyze the contents of elementary mathematics curriculum in order to help students to have ideas about the history of mathematics and to apply the ideas to develop their knowledge of mathematicians or mathematical history into the lesson ideas for preservice elementary teachers and elementary students. As a result, many ideas of mathematical connection into the history of mathematics are reviewed, and posters about Pythagoras and Pascal are designed to help students to reinvent the idea of triangular numbers and square numbers.

In this study, we designed and developed an ultrasonic transducer which can measure urine volume based on the estimation of distance between the interior-wall and posterior-wall of bladder. Measurement of urine volume is a way to help patients with urinary incontinence by detecting the amount of urine before the urine is released from the bladder. With the results of this experiment, we can measure the urine volume more accurately and also develop an incontinence preventive system. This study can help patients with urinary incontinence and enuresis to live longer, healthier lives.

This study examined mothers′ confidence in parenting practices for dealing with children′s emotional and behavioral problems, as well as the relationships between different confident parenting practices and their application to children′s behavioral problems. A total of 337 mothers of 4- and 5-year-old children responded to the Mother′s Questionnaire of Children′s Behaviors, with the following study results. First, the mothers showed high confidence in applying their own parenting practices to their children′s behavioral problems without outside help. Second, the parenting practice of "asking for help from family members" was related to children′s withdrawn behaviors, anxious behaviors, aggressive behaviors, social relationship problems, moral problems, and rule and courtesy problems.

This report contains information about "System Selection Assistant"(SSA) - Program, which can help customers of manufacturing company to select optimal electro-mechanical system for their purposes. This Program shows main principles of programs, which can help to make decision, using knowledge of experts. Program consists of two main parts: "Expert's part" must be tuned by expert and "Customer's part" can be used to make final decision about optimal parts of system. This report describes all parts of SSA program and shows simple example of selection parts of electro-mechanical system.

Technology competitiveness evaluates environmental and engineered technology and process at both the scientific and market levels. There are increasing concerns to measure the effects of the technology variables on the potential market feasibility levels. However, there are very little empirical analysis studies on that issue. This study investigates the impacts of technology variables on the levels of market feasibility based on 230 data obtained from Korea Technology Transfer Center. As various statistical analysis, the canonical discriminant model, logit discriminant model and classification model were used and their results were compared. This study results showed that major technology variables had very significant relations to discriminate high and low categories of market feasibility. Finally, this study will help building management strategies to level up the potential market performance and also help financial Institutions to decide funds needed for small-sized technology firms.

The critical problem of nurse scheduling in the hospital is determining the day-to -day shift assignments for each nurse for the specified period in a way that satisfies the given requirements of the hospital. As nurse scheduling involves many factors and requirements, manual scheduling requires much time and effort to produce an adequate schedule. A PC - based decision support system, developed in Turbo - C/sup ++/, for nurse scheduling was introduced. The system is composed of 4 sub-systems : 1) Entering basic information for each nursing unit : 2) Generation of an appropriate initial schedule and revised schedule for a given period, maximally satisfying each nurse's duty requests : 3) Provision of variety of statistical information, and 4) Help messages for each modular function. Icons and a mouse are used for easier graphic user interface and reducing the need for typing efforts. This system can help nurses develop quick and easy schedule generation and allow more time for the patient care.

Geocell is a three dimensional cellular confinement system that forms a reocomposite mattress with infill material to increase the bearing capacity dramatically rather than geotextiles of nonwoven and woven fabric type and geogrid. In terms of design, this geocell confinement is quite complex to assess and is different in its hieoretical evaluation and its concept from other geosynthetic products. Thsi study is aimed to help a basic understanding on Geoweb system, which is known to be the most effective and easiest in handling among the geocell systems ever developed, by introducing two method of interpretation for the improvement of bearing capacity. Thus the writers are sillingly to help the geotechnical engineers and the site engineers who might be encountered with the bearing capacity problems on site.

This study analyzed two dimensions hydraulic characteristic for actual flood events in steep meandering channel. It could get analysis results as follows; A water level difference of downstream more great than one of upstream at inner and outer of meandering channel. It judged that a significance of downstream level could appear more greatly in meandering channel bank, hydraulic structure and flood inundation analysis. As velocity and depth analysis was shown that much amount flow passing fast velocity happened in meandering channel, it could help establishment of meandering channel bank. In this study, the results of two dimension hydraulic analysis results could help a counterpaln establishment for the flood inundation and bank collapse.

A physically simple but mathematically cumbrous problem of rotating heavy chain with one fixed top point is studied. Nonlinear equation of its two-dimensional shapes of relative equilibrium is obtained and solved numerically. A linear case of small displacements is analyzed in terms of Bessel functions. The qualitative and quantitative behavior of the problem is discussed with the help of bifurcation diagram. Dynamics of the two-dimensional model near the equilibrium positions is studied with the help of simulation using the absolute nodal coordinate formulation (ANCF). The equilibriums are found instable, and the reason of instability is explained using a variational principle.
