This was a qualitative study to explore and better understand the adaptation experience and processes of peoples with fibromyalgia syndrome (FMS), as well as to develop a substantive theory using the grounded theory method. There were 13 patients (12 females and 1 male) who received FMS treatment from Rheumatic Medicine outpatient department of one general hospital. The data were collected through an in-depth interview between January and May of 2014. Transcribed interview contents were analyzed by the grounded theory method of Corbin and Strauss (2008). As a result, a total of 98 concepts, 26 sub-categories, and 10 categories were identified through the open coding process. The process of adaptation experience showed 4 steps: perception of uncertainty and limited condition, evaluation of self-control possibility and determinations of expectations of life, searching and trying of strategies, as well as self-regulation. The 4 types of adaptation experience were expansionary, complacently, effusively and withering. The 'protective self-regulation' theory was derived from the core category of 'learning to self-regulation method'. Patients with FMS has repeatedly attempted these strategies of protective self-regulation in order to gain stability from uncertainty and limited condition of the disease. Based on these results, it is necessary to develop an educational program for patients and families which has appropriate nursing intervention strategies in accordance with the types of adaptation.

This study was a qualitative research to investigate the adaptation process and stress experiences of female marriage immigrants to Korean culture, and to explore life experiences and meanings to cope with them. Participants in the study collected data through individual in-depth interviews targeting 5 female marriage immigrants with more than 5 years of marriage using the Healthy Families·Multicultural Family Support Center located in ◯◯-gu, Incheon City. Using the six steps of Braun & Clarke's topic analysis method, 3 main topics and 13 subtopics were derived. Research Results First, cultural differences experienced by female marriage immigrants in Korean life (daily life culture, tradition, family relations) Second, the cultural adaptation process experienced by female marriage immigrants (difficulties and fears-understanding cultural differences-efforts to overcome) Third, it was found that the cultural adaptation of female marriage immigrants is that Korean lifestyle becomes natural and familiar by knowing the difference in lifestyle between their mother country and Korean culture, and finding and practicing the way they want to live with Korean people. Based on the research results, a practical intervention plan for successful cultural adaptation of female marriage immigrants was presented.

The objectives of this study is to develop an adaptable digital wall model whose color can be changed dynamically according to the identified emotional state of a user. This study addresses how to capture a specific user's emotion through the web and use it for modifying VR model mainly for color adaptation. This adaptation process of a VR model consists of three phases: 1) identification of the user's emotional state projected onto the list of emotional keywords 2) translation of those captured emotional keywords into a pertinent set of color coordinations, and finally, 3) automated color adaptation process for the given model. This process derives an on-line viewer's emotional state, which can be utilized to find a new color scheme reflecting the identified emotion.

This study set out to investigate the adaptation process and experiential structure of those children who went through sexual abuse by looking into their inner worlds in order to understand what kind of meaning sexual abuse had on them. For that, the investigator conducted in-depth interviews with 13 children aged 8~16 who lived at the shelter after experiencing sexual abuse. The methodology of Grounded Theory by Strauss and Corbin(1990) was used to analyze raw data. The analysis results indicate that the core theme of the adaptation process among the children living at the shelter after sexually abused by kin and kith was "hoping to appear the same as others." According to the results, the core phenomenon was "blaming the victims." The causal conditions include "broken families," "antihuman sexual abuse," "making sexual abuse a public issue," and "the trap of the family." The contextual conditions include "the chain named family," "family as the last fortress" and "structural enforcement of silence." The intervening strategies was "dual emotions toward the shelter." The action/interaction strategies include "aftermath of violence" and "trying to escape." The consequences were "preparation for the future" and "uncertain future." The identified stages include the confusion, keeping the secret, leaking the secret to others, intervention by others, social support and challenge and adjustment stage. The three identified types were "withdrawal and avoidance," "settling down in reality" and "overcoming and challenging." Based on the analysis results, discussions were made about the social welfare plans and intervention strategies in the conclusion.

The purpose of this study is to examine the necessity of providing new perspectives by conveying the various psychological changes and realities experienced by victims of incest sexual violence after the incident, And it is meaningful to understand and record it through. The results of the analysis through the phenomenological methodology are as follows: First, participants were disturbed by the emotional neglect of their parents and forced violence, threats, and silence by their family members, resulting in disbelief in interpersonal relationships and low self-esteem and suffered constant difficulties in daily life. Second, the suffering and aftereffects of sexual violence experienced the conflict of roles by repeating the real maladjustment and social activity avoidance as the fear of being informed about the event, the negative thought about oneself, and the difficulty of interpersonal relationship. Third, the aftereffects of incest sexual violence in childhood·adolescence were found to be extreme with regard to PTSD. The PTSD experience has become a factor that forces participants to rely on substances, such as psychiatric medications and alcohol, and further avoids external activities with hallucinations and delusions. Fourth, the change through the adaptation process is a new perspective on life, facing and separating the events. During the adaptation program, they tried to express their words and feelings that they could not express because of the past hurts, to set goals for living their life, and to move forward. The experience of overcoming reality has enhanced participants' confidence in self-esteem, self-efficacy, and healthy self-control ability. In this study, it is meaningful to suggest a model in which the incest sexual violence trauma is reexperienced through the new daily crisis and the new adaptation process is repeated for each process.

This study verified the relationship between marital conflict perceived by working mothers and the influence of children's cyber delinquency and the mediating effect of school life adaptation. For the analysis data, the 14th data of the Korean Children's Panel (2021) were used, and SPSS WIN 23.0 and PROCESS MACRO were used for analysis. The analysis method used the PROCESS MACRO Model Number 4 technique to verify the hypothesis, first, frequency analysis to understand the demographic and sociological characteristics of the survey subjects, second, technical statistics, correlation analysis to understand the technical statistics and correlations of major variables. As a result of the main analysis, first, it was found that marital conflict perceived by working mothers did not have a statistically significant effect on children's cyber delinquency. Second, in the relationship between marital conflict perceived by working mothers and cyber delinquency of children, school life adaptation had a complete mediating effect. Based on these results, it is significant in that it has presented basic data to prevent cyber delinquency problems before children who are active a lot online are exposed.

This paper introduces a new monitoring technique which utilizes an adaptive signal processing for feature generation, coupled with a multilayered merual network for pattern recognition. The cutting force signal in face milling operation was modeled by a low order discrete autoregressive model, shere parameters were estimated recursively at each sampling instant using a parameter adaptation algorithm based on an RLS(recursive least square) method with discounted measurements. The influences of the adaptation algorithm parameters as well as some considerations for modeling on the estimation results are discussed. The sensitivity of the extimated model parameters to the tool state(new and worn tool)is presented, and the application of a multilayered neural network to tool state monitoring using the previously generated features is also demonstrated with a high success rate. The methodology turned out to be quite suitable for in-process tool wear monitoring in the sense that the model parameters are effective as tool state features in milling operation and that the classifier successfully maps the sensors data to correct output decision.

An adaptive model predictive control (AMPC) strategy using auto-regression moving-average (ARMA) models is presented. The characteristic features of this methodology are the small computer memory requirement, high computational speed, robustness, and easy handling of nonlinear and time varying MIMO systems. Since the process dynamic behaviors are expressed by ARMA models, the model parameter adaptation is simple and fast to converge. The recursive least square (RLS) method with exponential forgetting is used to trace the process model parameters assuming the process is slowly time varying. The control performance of the AMPC is verified by both comparative simulation and experimental studies on distillation column control.

Perhaps one of the most versatile approaches to learning in practical domains lies in case based reasoning. To date, however, most case based reasoning systems have tended to focus on relatively simple domains. The current study involves the development of a decision support system for a complex production process with a limited database. This paper presents a set of critical issues underlying CBR, then explores their consequences for a complex domain. Finally, the performance of the system is examined for resolving various types of quality control problems.
