It is Proposed thatthe Algorithm for Self healing to restoration the backup VP Occurrence Error in ATM Network. This study focuses on self-healing algorithm to restore failed VP. and backup-VP algorithm, one of the popular self-healing algorithm, is applied in this study. The problem with the existing algorithm is that when backup-VP is failed, there is no solution. This study proposes backup-VP algorithm to guarantee QoS in accordance with class. This study evaluates the effect of failure and proposes two algorithms. One is a disjointed path group to node pair class, and the other is one that applied different backup-VP case by case. Through simulation network restoring ability is compared, analyzed and synthesized.

In this study, the characteristics of Ultrasonic Transducer fabricated with PZT-Polymer 1-3 type piezoelectric ceramic/polymer composite are investigated. 3-D underwater object restoration using the self-made ultrasonic transducer and modified SCL(Simple Competitive Learning) neural network was presented. The ultrasonic transducer was satisfied with the required condition of commerical ultrasonic transducer in underwater. The modified SCL neural network using the acquired object data $16\times16$ low resolution image was used for object restoration of $32\times32$ high resolution image. The experimental results have shown that the ultrasonic transducer fabricated with PZT-Polymer 1-3 type piezoelectric ceramic/polymer composite could be applied for SONAR system.

Purpose. The purpose of this study was to obtain a clearer understanding of spirituality and examine the process of spirituality through defining the meaning and attributes of spirituality. Method. Concept analysis was done in the three phases, theoretical phase, fieldwork phase, and analytical phase suggested in the Hybrid Model. Five people participated in the fieldwork phase. Results. Spirituality is activated through self-awareness which occurs as spirit being activated through self-introspection, and through restoration of the relationship with Supreme Being. This interconnectedness with Supreme Being has an absolute impact on one's harmonious interconnectedness with self and neighbors, thus leads all the critical attributes of spirituality to be revealed. The core energy of this harmonious inter-connectedness is love. When activated, it has a great impact on an individual as integrative energy, leads one to go beyond everyday experience as well as to have new perspectives, and to live a satisfactory life in every aspect. Conclusion. The results of this study suggest that promotion of connectedness is the most important element in spiritual nursing interventions. The results can also be used effectively in developing spirituality assessment scales and theory.

Purpose: The purpose of this study was to understand and analyze the experience of restoration among Korean elders with suicide ideation. Methods: A phenomenological research method guided data collection and analysis. A total of five elders having had suicide ideation participated. Data were collected through individual in-depth interviews. All interviews were audio taped and transcribed verbatim. Coding was used to establish different concepts and categories. Results: As the results of analysis, the following three constituents have been found as a retrospective focus based on the primary suicide ideation: expanding their view and facing reality, reconstructing their view about life and death as well as self. Conclusion: The results of this study may contribute to health professionals working at various crisis settings to understand Korean elders with suicide ideation.

3-D object recognition and restoration independent of the translation and rotation using an ultrasonic sensor array, neural networks and invariant moment are presented. Using invariant moment vectors on the acquired $16{\times}8$ pixel data, 3-D objects can be classified by SOFM(Self Organizing Feature Map) neural networks. Invariant moment vectors kept constant independent of the translation and rotation. The experiment result shows the suggested method can be applied to the environment recognition.

A blast furnace slag(BFS) has been used as a filter medium for the treatment of domestic waste waters during the period of 9-month. More than 90% of phosphorus was removed while the hardness of the treated water increased by 5 times and the pH was significantly raised from 6.8 to 10.8. The high hardness and pH of the treated water indicated dissolution of BSF by the sewage. The experimental results suggest that BFS could be utilized for the removal of phosphorus in the waste water treatment plant using aquatic plants and gravels.

An object recognition and restoration using ultrasound sensors and neural networks are presented. The planar arrangement of the sensor is used to reduce the interference effects between sensors. The SOFM(Self-Organizing Feature Map) Neural Network and SCL(Simple Competitive Learning) method are learned with the acquired data. Lab experiments were performed that the object can be recognized ed the resolutions of the object can be enhanced by using the small number of the ultrasound array and neural networks.

Self-sufficiency has been recognized as one of the most important welfare goals for women in the domestic violence field since the welfare reform in the U.S. A qualitative research design was conducted to explore the self-sufficiency experience of Korean-American single mothers with the history of domestic violence in poverty. The meaning of 'self-sufficiency' to participants is that a continuing task or process in life to move toward being independent mentally as well as economically. Their challenges toward self-sufficiency include the period of restoration of their potentials for self-sufficiency destroyed by domestic violence victimization and divorce, and the period of developing their sustainability for self-sufficiency. Their needs for 'help and support similar to care from the woman's parents' home', 'welfare service of select and concentration', 'mature dependency and self-sufficiency', and 'self-sufficiency from survival to dream come true' to cope with the challenges formentioned are reported. Concrete strategies for the development of self-sufficiency polices and services sensitive to immigrant single mothers with the history of domestic violence are suggested.

The objective of this case report is to introduce a simple technique for simultaneously taking a closed-mouth impression and functionally generated path (FGP) for a full coverage crown restoration. A monolithic zirconia crown was the restoration of choice. An alginate impression of the abutment tooth was taken to fabricate a custom-made closed-mouth impression tray covering the abutment tooth and the adjacent teeth. The tray had an FGP table and an abutment tray in cameo and intaglio surfaces, respectively. The impression was taken with silicone impression material after adjusting the abutment tray and inscribing the FGP using self-curing acrylic resins. Plaster casts were made from the impression, and a zirconia crown was fabricated. The crown was cemented to the abutment tooth with minimal adjustments. This simple technique resulted in a well-fitting crown that accounted for mandibular movements. Using the custom closed-mouth impression tray incorporating an FGP table simultaneously aids in fabricating an accurately fitting restoration that incorporates harmonious mandibular movements using a single impression capture.

Purpose: The aims of this study were to evaluate the effect of a resin coating on the shear bond strength of indirect composite restoration bonded to dentin with a self adhesive resin cement and to compare the shear bond strength with that of a conventional resin cement. Materials and methods: The occlusal enamels of thirty six extracted noncarious human molars were removed until the dentin flat surfaces of the teeth were exposed. Then, they were divided into 3 groups. The dentin surfaces of group 1 and 3 were left without any conditioning, while the dentin surfaces of group 2 were resin-coated with Clearfil SE bond and a flowable resin composite, Metafil Flo. After all specimens were temporized for 24 hours, indirect composite resin blocks fabricated by Tescera were bonded to dentins by Unicem for group 1 and 2, and by Panavia F for group 3. After 48 hours of water storage, shear bond strengths were measured. The data was analyzed with one-way analysis of variance and multiple comparison test (Tukey method). Results: The shear bond strengths of Unicem applied to resin coated dentin surfaces were significantly higher than those of Unicem and Panavia F used to uncoated dentin surfaces (P<.0001). Conclusion: Application of a resin coating to the dentin surface significantly improved the shear bonding strength of a self adhesive resin cement in indirect restoration.
