Purpose: The purpose of this study was to explore mothers' adjustments in raising children with Down syndrome and to develop a grounded theory about their adjustments. Method: Three mothers from each group of children in the ages below 7 years, 8-13 years, 14-19 years, and over 20 years participated in the study. Data were collected through an in-depth interview from twelve participants having a child with Down syndrome. Then it was analyzed simultaneously using the grounded theory method. Results: 'Adjustment of mother's expectation according to child's status' was emerged as a core category. The adjustment process was categorized into five stages: shocking, embracing, doing one's best with passion, lowering anticipation, and accepting another living. Conclusion: Being the mother of a child with Down syndrome is not considered to be a negative experience. There are positive experiences along with some more negative ones. Nurses working with families that include children with Down syndrome need to be aware of the obstacles the families will face and should advise necessary support.

This paper presents a new vertex selection scheme for shape approximation. In the proposed method, final vertex points are determined by "two-step procedure". In the first step, initial vertices are simply selected on the contour, which constitute a subset of the original contour, using conventional methods such as an iterated refinement method (IRM) or a progressive vertex selection (PVS) method In the second step, a vertex adjustment Process is incorporated to generate final vertices which are no more confined to the contour and optimal in the view of the given distortion measure. For the optimality of the final vertices, the dynamic programming (DP)-based solution for the adjustment of vertices is proposed. There are two main contributions of this work First, we show that DP can be successfully applied to vertex adjustment. Second, by using DP, the global optimality in the vertex selection can be achieved without iterative processes. Experimental results are presented to show the superiority of our method over the traditional methods.

This paper present the optimal cleaning condition of the out-hull preprocessing robot by Taguchi method in design of experiments. A $L_8(2^4)$ orthogonal array is adopted to study the effect of adjustment parameters. The adjustment parameters consist of robot speed, motor torque, motor speed and tool angle. And the quality feature is selected as surface roughness of sheet metal. Taguchi analysis is performed in order to evaluate the effect of adjustment parameters of the quality feature of cleaning process by $Minitab^{(R)}$.

The automation system oriented as one of the second year automation projects for the small and medium sized enterprises(SME) was developed for the improvement of the production rate and cut the required manpower in the field of the relay which is one of the small electric components used in various industrial fields. The objectives of this study are not only improving the international competition of the relay itself but also partially solving the technical and financial problems featured by common bottlenecks of the SME for efficient assembly automation. For the purpose of these objectives, several topics are studied as followings. - Analyzing the adjustment process and determining the specification of the automation system. - Determining the layout for the automation system to meet the determined specification. - Detail design of the automation system for relay adjustment and inspection. - Control system design - Automation system development and performance test.

There are many kinds of maintenance care services for removable denture patient. Adjustment of the denture base and occlusion should be performed regularly not only for pain relief but also for maintaining the denture function. Direct and indirect relining are needed frequently in specific cases including mandibular distal extension case or non-symmetric residual teeth situation. Surface treatments for metal and resin are essential in the relining procedure. Clinical process for the denture repair is similar to indirect relining which needs inter-occlusal registration. Especially, the peridontal maintenance care and caries prevention are most important way to preserve the abutment teeth in partial edentulism. Moreover, the caring method for the denture and the tissue should be instructed to the denture patient.

The purpose of this study was 1)to examine the effect of various stress on adjustment in terms of depression and well-being, 2) to examine whether the widow's self complexity and coping behavior mediate the effect of various stress on adjustment . The subject was composed of 117 women in the first 7 years of their widowhood. The major results of findings were as following: 1. Widows experienced children-related stress(54.7%), financial stress(47%), emotional loneliness(42.7%), relational stress(34.2%), and instrumental stress(27.4%) in their order. 2. Widows who experienced emotion loneliness had high depression and low well-being. And Widows who experienced financial stress reported low well-being. 3. When widows experienced instrumental stress, Widows who had high active coping behavior reported high well-being than widows who had low active coping behavior.

The purpose of this research was to develop the education program for post-divorce adjustment and to evaluate effectiveness of the program. This program was consisted of eight sessions and applied to divorced parents. It was focused for the understanding of grief processes for adults, recovery by forgiveness, children's responses and coping strategies to divorce, open minded relationship between parents and children, and enhancement of self-esteem to be healthy single parent. Results of paired t-test showed that there were significant differences between pre-test and post-test, and the effectiveness remained until follow-up. In conclusion, this program was thought to be effective for improving self-esteem, divorce coping competency and minimizing of the depressions. Continual education is thought to be necessary for maintaining of the effectiveness to the divorced parents.

There have been a number of empirical studios on the effectiveness of Judgmental adjustment to statistical forecasts Generally the results have been mixed. This study examined the impact of the reliability and the source of the additionally presented reference forecast upon the revision process in a longitudinal time series forecasting task with forecast support systems. A 2-between(reliability ＆ source). 2-within(seasonality ＆ block) factorial experiment was conducted with post-graduate students using real time series. Judgmental adjustment was found to improve the accuracy of initial eyeballing irrespective of the reliability of an additionally presented forecast. But it did not outperform the dampened reference forecast. No effect was found of the way the source of the reference forecast was framed. Overall the subjects anchored heavily on their Initial forecast and relied too little on the reference forecast irrespective of its reliability. Moreover they did not improve at the task over time, despite immediate outcome feedback.

In this paper, we consider the adjustment of convergence on Color Display Tube (CDT). Convergence is a measure of how well the red, green and blue beams are physically aligned with each other to strike the same area on the screen. When misconvergence (convergence error) occurs, one way of compensating it is to attach several ferrite sheets on the inner part of Deflection Yoke (DY). We suggest an optimization model of misconvergence compensation process and report test results for 81 DY samples. As a result, more than 90% of the samples could be made to satisfy the required convergence criteria.

Generally, sensor nodes can be easily compromised and seized by an adversary because sensor nodes are hostile environments after dissemination. An adversary may be various security attacks into the networks using compromised node. False data injection attack using compromised node, it may not only cause false alarms, but also the depletion of the severe amount of energy waste. Dynamic en-route scheme for Filtering False Data Injection (DEF) can detect and drop such forged report during the forwarding process. In this scheme, each forwarding nodes verify reports using a regular probability. In this paper, we propose verification probability adjustment scheme of forwarding nodes though a fuzzy rule-base system for the Dynamic en-route filtering scheme for Filtering False Data Injection in sensor networks. Verification probability determination of forwarding nodes use false traffic rate and distance form source to base station.
