With the dynamically changing environment of society, managing change is the vital element of organizations's survival and growth. Health care organizations have expended enormous resources to restructure patient care delivery. Despite the growing literature describing these organizational innovations, there is a paucity of credible data that reflects systematic measurement and evaluation of such changes. This study examined the nurses' psychological response toward the work process redesign, newly introduced by the nursing department in a acute care hospital. The aim of the study was to figure out how nurses's general perception of change and perceived attributes of change affected their acceptance of change during the organizational transition. This was descriptive- correlational. The sample for the study included 50 head nurses and 135 staff nurses. Data was analyzed using SPSS PC+, version 10.0. The major findings of the study were as follows: First, the mean score of the perception of change was 71.2(SD=13.8) with the range of 0-100, which means nurses generally perceived change positively. There were significant differences in perception of change by gender and education level. Head nurses perceived change more positively than staff nurses. The higher education level showed the more positive view of change. Second, among the perceived attributes of change, trialability had the highest mean score, which means nurses perceived the change more positively if it is testable on a limited basis. Relative advantage was perceived the most negatively. Finally, factors influencing the acceptability of the work-process redesign were perceived comparability, complexity, relative advantage, and observability, which accounted for 43.7% of the variance in the acceptability of change. This study evaluated the preliminary effects of the nursing process for reengineering, focusing on nurses' acceptability towards change. The usefulness of this research study was to determine the factors influencing acceptance of organizational members during transitional periods of change and to suggest effective strategies for increasing adoption as well as for decreasing resistance to change.

The purposes of this study were to analyze and understand the life of mothers rearing children with Down syndrome and to present basic data for overcoming the difficulties of those families. For these purposes, this study made use of the phenomenological analysis and approach with a qualitative research method. The subjects of this study are 4 mothers rearing children with Down syndrome who are beyond school age. The results were as follows. First, the reason why mothers with Down syndrome children went through psychological shock and horror was the social stigma due to the unusual appearance of children with Down syndrome. Second, the isolation with in the public education system was disclosed as a factor causing much sorrow and pain. Through this, we can recognize the importance of ensuring the equal right to receive education of children with Down syndrome. Third, the period which the mother experienced most shock and confusion was right after finding out about the disability that her child has. So, we can identify the importance of early intervention providing psychotherapy and rearing service to the parents. Fourth, the crucial factor that relieved pain and pressure from mothers was social support including family. Therefore, the social support system for mothers with Down syndrome children has to be developed and strengthened. Fifth, the crucial factor that made mother grow up during rearing experience was the reestablishment of cognition about the desired role of mothers. Through this, we can identify the importance of the mental transition process to independent thinking.

Mathematical formal justification may be seen as a bridge towards the proof. By requiring the mathematically gifted students to prove the generalized patterned task rather than the implementation of deductive justification, may present challenges for the students. So the research questions are as follow: (1) What are the difficulties the mathematically gifted elementary students may encounter when formal justification were to be shifted into a generalized form from the given patterned challenges? (2) How should the teacher guide the mathematically gifted elementary students' process of transition to formal justification? The conclusions are as follow: (1) In order to implement a formal justification, the recognition of and attitude to justifying took an imperative role. (2) The students will be able to recall previously learned deductive experiment and the procedural steps of that experiment, if the mathematically gifted students possess adequate amount of attitude previously mentioned as the 'mathematical attitude to justify'. In addition, we developed the process of questioning to guide the elementary gifted students to formal justification.

This work focuses on the electrical conduction mechanism in a lead free ($Na_{0.5}K_{0.5}NbO_3$ ; NKN) ceramics system with $LiNbO_3$ content of approximately critical concentration $x{\geq}0.2$. Lead free $(1-x)(Na_{0.5}K_{0.5})NbO_3-x(LiNbO_3)$, $NKN-LN_x$ (x = 0.1, 0.2) ceramics were synthesized by solid-state reaction method. Crystal structures are confirmed by X-ray diffraction. The electric-mechanical bond coefficient $k_p$ decreases and the phase transition temperature $T_c$ increases with increasing x content, as determined by dielectric and piezoelectric measurements. The value of the real dielectric constants ${\varepsilon}^{\prime}$ and $k_BT{\varepsilon}^{\prime\prime}$ showed anomalies around $T_c$ ($462^{\circ}C$ in the NKN-LN0.1 and $500^{\circ}C$ in the NKN-LN0.2). For the ionic conduction of mobile ions, the activation energies are obtained as $E_I=1.76eV$ (NKN-LN0.1) and $E_I=1.55eV$ (NKN-LN0.2), above $T_c$, and $E_{II}=0.78$ (NKNL-N0.1) and $E_{II}=0.81$ (NKN-LN0.2) below $T_c$. It is believed that the conduction mechanisms of NKN-LNx ceramics are related to ionic hopping conduction, which may arise mainly due to the jumping of $Li^+$ ions.

Currently, the Ministry of Employment and Labor is strengthening monitor programs in regards to occupational industrial safety and health act compliance in business operations. However, industrial accidents occur persistently. Therefore, the study strives to diagnose and understand the issues in its educational stature, targeting managing supervisors in large scale shipbuilding industry whose completed the regular safety and health act sessions. This research considered a total of 3,252 employees whose completed theory-based cluster sessions for three months since February, 2016. The group is divided into two categories; 551 participants whose completed 8 hours of training and 2,701 participants whose completed 4 hours of training. Technical statistics were used to measure the knowledge of safety and health, educational environment, curriculum and educational effects on managing supervisors. A t-test was used to analyze the difference between the training hours. The result indicated that the target participants' knowledge on safety and health before the session was 50.24 points average (100 point scale), showing low standards in general. In depth analysis indicated that both 8 hours and 4 hours groups scored lowest in educational methods and communications between the lecturer and participants factors within the educational curriculum category. Meanwhile, transition in knowledge acquirement, work attitude, and work behaviors scored the highest in the analysis, showing a high satisfaction factors in educational effects. Therefore, the improvement in educational time and period can increase the efficacy of the educational programs. Also, theory-based cluster programs based on lectures suggests positive influence in knowledge acquirement and behavioral transitions.

This paper describes a novel Context-awareness Markov Chain Prediction (CMCP) algorithm based on movement prediction using Markov chain in Delay Tolerant Network (DTN). The existing prediction models require additional information such as a node's schedule and delivery predictability. However, network reliability is lowered when additional information is unknown. To solve this problem, we propose a CMCP model based on node behaviour movement that can predict the mobility without requiring additional information such as a node's schedule or connectivity between nodes in periodic interval node behavior. The main contribution of this paper is the definition of approximate speed and direction for prediction scheme. The prediction of node movement forwarding path is made by manipulating the transition probability matrix based on Markov chain models including buffer availability and given interval time. We present simulation results indicating that such a scheme can be beneficial effects that increased the delivery ratio and decreased the transmission delay time of predicting movement path of the node in DTN.

The photoelectric effect is a representative phenomenon explaining the particle nature of light and is an important theme that led to the transition from classical physics to modern physics. Although the secondary school curriculum deals with the photoelectric effect, teachers and students are often confused with terms because the explanation of the 'light intensity' is different from that of electromagnetic waves. Hence, this study examines how modern physics textbooks explain the intensity of light through photon model. We analyzed the photoelectric effect unit of 10 modern physics textbooks. Results show that there are two different types of representation on 'light intensity.' Especially those two different types were found even within a textbook. Modern physics textbooks do not seem to provide a unified presentation of the light and cautions to describe the photoelectric effect and its interpretation are suggested for teaching light intensity in modern physics.

Loss has been expanded to include not only death but also the change that take place in the transition of life. In addition, the rate of direct and indirect experience of death around us has increased due to natural disasters and unexpected accidents. Therefore, there is a growing demand for grief counseling and a need for professional grief counseling. The purpose of this study was to investigate the competency of grief counselors and to review on the literatures what grief counselors should be trained to improve their professional competences. Specifically, there were grief counseling theory, evaluation of grief, death education, and counselor self-care. There were suggested that how to integrate into existing counselor curriculum and introduced experiential practice. This study can be used as a basic data for encouraging the attention of grief counselor education and competency model.

This study aims to examine the transition of the youth to the labor market by types of education and training institutes focusing employment rate. To construct the dataset for the analysis, the list of the graduates from 4-year universities, junior colleges, polytechnic colleges and the graduates from vocational training institutes as of February 2001 has been merged with the database for the insured in the Unemployment Insurance Database. This data enables tracking down of these graduates in terms of their mobility in the labor market. For graduates from universities and junior colleges, their scores on the Scholastic Aptitude Test have been matched. One of major findings is that the longer the schooling period is, the better the employment results are. Among those who finished 4-year universities, those who went to schools in the metropolitan area achieve a relatively better record in job finding than those who attended schools in the local areas. Meanwhile it is confirmed that the SAT score is highly co-related with the performance in the labor market among those who finished 4-year universities. The co-relation of one's major with his/her employment is not negligible also.
