This study was conducted to investigate the extent to which the teachers in disability welfare facilities are acquainted with the oral health knowledge. It was compiled by means of the self-administered questionnaire held out by 119 teachers in Gimhae and it conducted in August of 2010. Considered the score of 100 as all the precise answers, the total average score was 46.4(${\pm}18.0$). Moreover, the heterogeneity of the oral health knowledge among the respondents was revealed that it statistically does not have anything to do with the demographic characteristics. In conclusion, it is urgently required to develop the oral health education in forms of the continuing education, the online education, and the materials of the regular university curriculum - all for the teachers of the disability welfare facilities in Korea.

The TMN that appears to operate the various communication networks generally and efficiently is developed under the different platform environment such as the different hardware and the different operating system. One of the main problems is that all the agents of the TMN system must be duplicated and maintain the software and the data blocks that perform the identical function. Therefore, the multi-platform cannot be supported in the development of the TMN agent. In order to overcome these problems, the Farming methodology that is based on the Farmer model has been suggested. With the Farming methodology, the software and the data components which are duplicated and stored in each distributed object are saved in the platform independent class repository (PICR) by converting into the format of the independent componentware in the platform, so that the componentwares that are essential for the execution can be loaded and used statically or dynamically from PICR as described in the framework of each distributed object. The distributed TMN agent of the personal communication network is designed and developed by using the Farmer model.

Fuzzy theory is used to quantify some subjective criteria and consider uncertain factors for transmission line reinforcement planning in this paper. Sugeno's fuzzy integral is also used in the proposed method, because it can be easily allied to multi attribute decision making problems such as power system planning. To verify the proposed algorithm, some bode-neck lines are searched for the case that the amount of Maximal Load Supplying Capability(MLSC) is small using the results of contingency analysis for Korea Electric Power Corporation(KEPCO)'s 345[kV] transmission line in 1998. And several feasible alternatives are composed for line reinforcement which can dissolve the bottle-neck.

This paper deals with the linear matrix inequality (LMI) design procedures for multi-objective Η$_2$/Η$_{\infty}$ controllers with pole-placement constraints for an inverted pendulum system modeled as convex polytopes to ensure the stabilizing regulator and tracking performances. Polytopic models with multiple linear time-invariant models linearized at some operating points are derived to design controllers overcoming the conservativeness such as a controller may have when it is designed for a model linearized at a single operating point. Multi-objective controllers are designed for polytopic models by the LMT design technique with convex algorithms. It is observed that the inverted pendulum controlled by any controller designed for each polytopic model is stabilizingly restored to the vertical angle position for initial values of larger tilt anlges.

This paper proposes and implements an on-line instruction manual system which can generate the instruction manual page for the target device at the smartphone on the spot. The instruction manual app. on smartphone scans a QR code or reads NFC tag attached in the instruction manual management module embedded in the target device, and receives instruction manual data from the instruction manual management module through the Bluetooth communications and finally shows the refined instruction manual pages on the smartphone display using a Web-based templates. For the evaluation we embedded the instruction manual management module for an industrial generator with its instruction manual data. Assuming a circumstance of blackout we show that the proposed system can reduce the repair work within two steps compared to three steps in the existing one without the proposed system.

This study explored the prospects and tasks of accreditation system for instructional materials and equipment in early childhood education. Various aspects of accreditation system, such as necessities of evaluation system, thoughts regarding evaluation system, necessities of categorizing standards, and necessities of constructing accreditation system were discussed based on previous research. Also other aspects of accreditation system which were not considered in the previous research, such as thoughts related with instructional materials and equipment being evaluated and considerations regarding evaluation indexes were explored.

Recently, safety accident by misstep at the gap between the platform and railway vehicle have frequently occurred to the mobility handicapped including disabled person, children etc. in metropolitan subway region. Particularly, because the curved platform's gap from platform to railway vehicle is max. 260mm it is important to securement of the passenger's safe mobility right. So it is necessary to platform safety step equipment for needs technology to interface gap between the platform and railway vehicle. In this study we examined the function & production requirements of platform safety step and performed the conceptual design considering the crash safety and maintenance easiness. Moreover, considering various performance requirements we suggested step's operation procedure & control flowchart.

The present research aims to analyze empirically the effect of group cohesiveness and supervisor trust which tax investigators recognize while performing tax administrative duties on the team commitment and in-role behavior. The result of the analysis showed that tax investigators' higher group cohesiveness and supervisor trust resulted in higher team commitment, and that higher team commitment in turn resulted in higher in-role behavior, thereby raising the efficiency of tax investigators' activities as well as tax payers' satisfaction with tax services. Therefore in order to improve the efficiency of tax organizations and team performance, the managers of the organizations must set solid goals, develop solid strategies appropriate for situation, and make proper compensations for investigators' achievements. In addition, there would have to be an organic improvement In all the relevant areas, including organization, personnel management, work style, compensation and welfare, in order to raise tax investigators' work desire.

It takes quite a long time for an analyzer, such as gas chromatography, to measure a bulk property of a system, which prevents on-line measurements. Also, the cost of installation and maintenance is very high. Consequently, some other means is needed for on-line measurements of properties and the development of soft sensors based on process variables like temperature and pressure is of great interest. In the field of gas industry, the development of a soft sensor which makes indirect on-line measurements of gas compositions and flow rate, is in progress. In this paper, we proposed a hybrid inner model PLS which improved the prediction performance by taking into account the data structure, as an empirical modeling algorithm. When applied to a design of a soft sensor of a distillation tower, the hybrid inner model PLS showed better prediction performance than other methods.

This study examines self-reflexive scenes of Changgeuk [창극; Korean classical opera] Seopyenje [서편제]. This show deals with Pansori [판소리; a kind of Korean folk play] and its singers. The uniqueness of this show is that although it is a new creative work of Changgeuk, the traditional Pansori music is used intactly. These characteristics are related to some self-reflexive scenes in the show: the narcissistic reference of Pansori makes to seem that this show inherits a artistry of Pansori; a play within a play and a role-play reinforce a reality on the action and characters of outer play; an intertextuality, bringing the narrative and music of Pansori Simcheong-ga [심청가] in this show, it makes audiences spontaneously discover a connection between the cited original text and the hypertext. Namely, the self-reflexivity of Changgeuk Seopyenje doesn't destroy an illusion, but rather it presents a kind of conservative self-reflexivity which uncovers a part of tricks for the illusion in order to create new illusion.
