The concept of 'the lunar and planetary phases' is very difficult to understand and students may have various misconceptions on this concept. A module drawing the lunar and planetary phases was developed with the application of the simplifying conditions method. The effects of instruction using the module drawing the lunar and planetary phases on the conceptual change and the achievement was investigated in the consideration of learners' characteristics (spatial perception ability, science inquiry ability, required pre-requested learning ability). Findings were as follows: 1) This module was effective for learners' conceptual change and achievement, 2) This module had a positive influence for development the learners' characteristics and conceptual change with the middle level of science inquiry ability, the middle and low level of required pre-requisite learning ability, and middle level of the spatial perception ability.

This study has developed the sex education contents including new natural family plan, concept and principle by receiving the opinions and advices from professionals and professors on sex education, by amending and supplementing existing teaching materials on sex, and examining the books related with sex education contents that reflect the request of teachers and students, and the lack of sex education teaching materials which have been the reason that needs of school sex education has been highly recognized but not vitalized. The developed sex education contents are 8 areas such as knowing my body right, caring my body, observing the ability of being pregnant, marriage, sexual intercourse, process of pregnancy, miscarriage, and sexual violence, 30 lower areas, and 105 detailed contents in their composition, and here are the results of analyses of the degree of request of nurse teachers and the students on them. The teachers showed highest request in the area of sexual violence(M =4.67), the next was my body care(M=4.44), knowing my body right(M =4.38), process of pregnancy(M=4.13), marriage(M=4.11) and sexual intercoursen (M=3.98), ways of judging the ability of being pregnant(M=3.88), and miscarriage(M=3.72) showed comparative higher request than normal. Not like the teachers, the students showed that they requested Marriage area as the highest need(M=3.04) and next was sexual violence(M=3.02), caring my body(M=3.00) to have been higher than normal. Process of pregnancy(M=2.99), Sexual intercourse(M=2.81), miscarriage(M = 2.77), observation of the ability of being pregnant(M=2.74), and knowing my body right(M=2.70) have been the requests lower than normal. This study showed that sexual violence, marriage, caring my body, were the items most requested by both the leacgers and students and in elementary school the development of sex education teaching materials on natural family plan suitable to the level of development of the children has been requested as it has had no inclusion of the concept of natural family plan, and the students in elementary school are concerned on indirect sexual contents related with physical health like regular exercise rather than direct sexual education contents including sexual intercourse. All these show that they are still so naive on sex. The sense of the teachers on sex has been connected with the level of achievement of sex education of the children as it has been the important cause of deciding the contents of sex education. Therefore the materials developed onesidedly by leaders without reflecting the needs or the preference of the students might be worries of bringing shameful. low quality and negative opinions on sex, and on the other hand the children might lose the concerns and interest on sex education, So the materials should be developed to have the contents of sex education coinciding with the request of the children.

Radiologic images in dentistry are essential to perform the diagnosis, treatment, and tracking process of prognosis, thus the ability of accurate evaluation in the diagnostic images is requested for dental clinician. Radiologic interpretation means recognition of a normality and an abnormality and to report the possible diagnosis and differential diagnosis list. Therefore, dental clinicians should be familiar with the basic principle of interpretation of intraoral and extraoral radiographic images primarily used in dental clinics. Recently, dental cone beam CT is widely used for diagnositc process, thus understanding the three dimensional images is requested. The objective of this manuscript is to help the dental clinicians to interpret accurately the diagnostic images by introducing the basic principles of the step by step analytic process in the appearance of a lesion.

In this paper, we propose the redirect streaming service model to enhance resurgent ability. The system consists of a redirect server, local streaming servers and clients. A redirect server searches the best streaming server. And streaming servers starts a requested service or resumes it when in a trouble. RTSP/RTP is one of the effective solutions to improve QOS in VOD, however a service can be broken off by an overloaded server or network especially in live. We designed and implemented not only a distributed streaming system that solves the broken-off service to enhance a resurgent system, but also DSSP, distributed streaming service protocol, which is adopted to implement this model. Those will improve the performance of streaming service using RTP/RTSP and be contributed to a real time streaming research to solve a service trouble.

The construction industry highly depends on each specialized manager which is essential to successful project. However, a new employee, who has just graduated from architectural engineering college, is requested additional education for 1~2 years such as On-the-Job-Training (O.J.T) to perform his/her professional job in construction site. It is wasteful for both construction company and the employee in terms of time and cost. The purpose of this paper is to investigate the required abilities and analyze the gap of demanded abilities between field managers and students. To collect data for analysis, questionnaire which uses Likert Scale has been performed to both parts. As a result, the analysis show that the graduate's abilities related to field experience get especially low degrees in compare with non-field experience factors. These results will contribute architectural engineering education in college to make more realized.

The purpose of this study was to investigate the effect of early educator's psychological exhaustion and happiness on adapting ability of children in early education settings. Two hundred ten early educators and six hundred thirty children were selected as subjects of this study and were requested to participate in a survey. The results of this study were as follows: First, as a result of analyzing the relationship between early educator's psychological exhaustion and happiness as well as children's adaptability on education facility, higher psychological exhaustion and lower happiness were related to lower children's adaptability on education facility. Second, as a result of comparing comparative impact that psychological exhaustion and happiness has on children's adaptability on education facility, psychological exhaustion of the teacher impacts negatively on children's adaptability on education facility and happiness of the teacher did not significantly impact children's adaptability on education facility. This research is expected to be used as foundational data that helps to recognize the importance of psychological exhaustion and happiness of the teacher and could be used to develop various programs that support teachers to recover from burnout and to increase happiness.

As the population of senior citizens has been increasing very rapidly, the importance of their education is gradually emphasized. To maintain their mental and physical health, the solution on the biological, physical, and educational approach might be helpful and effective. Especially in the aspect of the educational approach, the mathematics education can be regarded as an important subject for keeping the seniors in a good mental health. The reason is that the ultimate goal of mathematics education is to pursue an enhancement of mathematical thinking ability. By the reason, this study aimed to develop mathematical materials for enhancing seniors' thinking ability, and the seniors usually belong to fifties and sixties. To this purpose, this study selected the six essential mathematical thinking elements and four mathematical domains of 'number and operation', 'shape and measurement', 'possibility', and 'patterns'. Based on these elements, the mathematical materials including the nine types of activities using games and commercial manipulatives were developed. On the subject of 52 female seniors, the instruction was conducted using a part of the materials during 100 minutes. Also, 13 survey items were developed beforehand, and the survey was implemented after the class, and eventually 48 seniors responded in the survey. As a result, it is meaningful to develop the materials not only for enhancing mathematical thinking ability but for understanding and utilizing the content of materials. Furthermore, it is requested that those materials be differentiated according to the degree or the difference of age, academic ability, and sex.

EDS is a typical convergence service performing convergence between functions owned by multiple SPs. EDS provides users with the relevant information and the communication by the various personal conditional environment. An alternative terminology for events for net- work related applications is 'triggers'-these are assumed to be included in the present description. Events could be defined as any activities which occur within a service avail ability, signals. Events can be managed, for example, as part of a context-aware application. EDS carry out a procedure for processing user's requested information about mobil network-based entities, such as the combination with various applications, such as a LBS (Location Based Service) and area information. In AS (Application Service) network environments, the user has his customized EDS in the network, the EDS automatically connects the appropriate Terminals consistent with a user profile. EDS can also send the collected information to other requesting users by way of event information and using the procedures of combination with other services. The user can record/retrieve the user-related information to from the information base through EDS.

Developing a home network and a ubiquitous infrastructure requires various communication techniques and devices with more advanced hardware. With this development, increasing realtime access to multimedia data results in rapid degradation of qualify for multimedia playback. This paper presents a traffic allocation technique based on MPP(Media Preference for Presentation) that can steadily maintain multimedia playback quality by adaptively allocating streaming traffic requested from clients with different playback performances. Media preference is defined in accordance with content popularity and playback performance of client devices. Through experiments when requested stream data exceeds processing ability of a midea server, the proposed allocation technique shows 10% quality improvement comparing to the system without applying the proposed allocation technique.
