Purpose: The main purpose of this study was to observe the adaptation experience process of adolescents with hematologic malignancies. Methods: The Grounded Theory Method, developed by Strauss & Corbin (1998), was used in this study. The data were collected through in-depth. interviews with 10 adolescents with cancer. Data collection and analysis occurred concurrently. Theoretical sampling technique was used until the data reached saturation. Results: "A deviated life" was verified as the central phenomenon for adolescents with cancer. The adaptation experience process was divided into 3 steps: "Self-confusion", "Reinterpretation", and "Regeneration of self". Through these 3 steps, the adolescents with hematologic malignancies fitted a new life by self-integration. Conclusion: The results of this study provide a frame for individualized nursing intervention strategies in helping with the psychosocial adaptation of adolescents with hematologic malignancies.

In this research, hybrid method with case-based reasoning and rule-based reasoning is applied. Using case-based reasoning, design experts'experience and know-how are effectively represented in order to obtain a proper configuration of midship section in the initial ship design stage. Since there is not sufficient domain knowledge available to us, traditional case-adaptation algorithms cannot be applied to our problem, i.e., creating the configuration of midship section. Thus, new case-adaptation algorithms not requiring any domain knowledge are developed antral applied to our problem. Using the knowledge representation of DnV rules, rule-based reasoning can perform deductive inference in order to obtain the scantling of midship section efficiently. The results from the case-based reasoning and the rule-based reasoning are examined by comparing the results with various conventional methods. And the reasonability of our results is verified by comparing the results wish actual values from parent ship.

In this paper we present a new approach to estimate link travel speed based on the hybrid neuro-fuzzy network. It combines the fuzzy ART algorithm for structure learning and the backpropagation algorithm for parameter adaptation. At first, the fuzzy ART algorithm partitions the input/output space using the training data set in order to construct initial neuro-fuzzy inference network. After the initial network topology is completed, a backpropagation learning scheme is applied to optimize parameters of fuzzy membership functions. An initial neuro-fuzzy network can be applicable to any other link where the probe car data are available. This can be realized by the network adaptation and add/modify module. In the network adaptation module, a CBR(Case-Based Reasoning) approach is used. Various experiments show that proposed methodology has better performance for estimating link travel speed comparing to the existing method.

Recently, character motion have been used extensively in the entertainment business, and researchers have investigated algorithms of reproducing, editing, and simulating mimic human movements. Also, many recent researches have suggested how a character interacts with its surrounding environment in terms of motion. Specially, spatial relationships of the environment have been introduced for adapting and preserving character motion. In this paper, we propose a motion adaptation technique preserving a spatial property between a virtual character and the configuration of its surrounding space. Additionally, we report on experimental results of smoothly adapted motions in various environmental structures with original motions such as walk, jump, and tumbling.

This study aims to investigate the stress factors of students in Dental Hygiene Department who will soon take the national examination, corresponding countermeasures and relationship of internal and external personality. On the basis of the results from investigation, this study will identify the methods to effectively cope with stress and to take the national examination with more positive thinking for the students and faculty members in Dental Hygiene Department, who have to pass the difficult test, the national examination. The structured questionnaires were given to junior students in Dental Hygiene Department in three colleges, to identify the stress factors, methods to deal with stress and A/B personality types. For the stress factor by field, the M college showed significantly higher stress about curriculum and assignment than the C college. In the stress factor analysis by item, the lack of information on national examination in the test area, all items in learning environment, a quantity of assignment that doesn't help the preparation of national examination in the assignment area, and lack of information on employment in job area demonstrated the significant difference(p<0.05). For the methods of subjects to deal with stress, several subcategories of long-term and short-term adaptation had significance. In case of the methods to deal with stress by personality type, B type in the short-term adaptation method in M college and A type in the long-term adaptation method in C college were significantly higher(p<0.05). As for the correlation between the population sociological features and stress factors by personality type, health status had the high correlation with test in the test area. In other areas, the travel hours to school showed the significant correlation. The higher the records were, the longer the travel hours were and the better the health status was, the higher the long-term adaptation method scores were. Moreover, the personality of A type showed the higher scores in the long-term adaptation method than that of B type. The health status and personality type showed the significant correlation(p<0.05). In conclusion, it is required to prevent any situations b identify the personality type and stress reasons of the students in Dental Hygiene Department who will take the national examination soon. The additional requirement is the continuing interest and counseling of faculty members to help students to cope with stress with positive attitude.

In traditional approaches to scheduling problems, a single dispatching rule was used by all machines in a system. However, since the situation of each machine generally differs from those of other machines, it is reasonable to apply a different dispatching rule to each machine responding to its given situation. In this regard, we introduce the concept of spatial adaptation and examine its effectiveness by simulation. In the spatial adaptation, each machine in a system selects an appropriate dispatching rule in order to improve productivity while it strives to be in harmony with other machines. This study proposes an adaptive procedure which produces a reliable dispatching rule for each machine beginning with the bottleneck machine. The dispatching rule is composed of several criteria of which priorities are adaptively weighted. The weights are learned for each machine through systematic simulations. The simulations are conducted according to a Taguchi experimental design in order to find appropriate sets of criteria weights in an efficient and robust way in the context of environmental variations. The proposed method was evaluated in an application to a semiconductor wafer fabrication system. The method achieved reliable performance compared to traditional dispatching rules, and the performance quickly approached the peak after learning for only a few bottleneck machines.

Each year, significant amounts of Stereoscopic 3D(S3D) contents have been introduced. However, viewers who enjoy the contents readily experience a sense of fatigue on account of various factors. Consequently, many improvement studies have been conducted with the domain of disparity by, for example, simply controlling the disparity or optimizing the reaction speed of viewers' eyes to vergence. However, such studies are limited to the disparity domain and therefore are restricted to a limited number of applications. In this study, we attempted to transcend this limitation and analyzed how a reconstruction in color and brightness, as well as disparity and other important features, affects eyes in terms of vergence adaptation. As a result, we found that, the higher the color similarity is, the better it positively affects vergence adaptation during viewing. Based on this analysis, we propose in this paper a similar color extraction method between takes that are applicable to real-life situations. In an evaluation, the algorithm was applied to publicly available S3D contents and produced a converted color optimized image. The vergence adaptation time of this applied contents was significantly decreased. Also it was minimized through color reconstruction, thereby, being resulted in enhancing viewer concentration.

Purpose : This study develops a substantive theory on the recipients' experience of adapting to a permanent pacemaker. Method : The study used the grounded theory method developed by Strauss and Corbin (1998). The participants of the study were 13 adults who had received a permanent pacemaker during the previous year. The study addressed the research question "what is the experience of adaptation in people who had received permanent pacemakers?" From October 2016 to March 2017, data were collected from the participants through in-depth interviews. Results : The core category indicating the essence of the adaptation experience was shown to be "accepting the pacemaker as part of my body and living in line with it." Conclusions : In nursing practice, the results of this study will assist nurses in improving their communications with and developing guidelines or interventions for their clients who have received permanent pacemakers. In the field of nursing education, this study is expected to provide a framework to understand the experiences of future nurses and other healthcare workers working with permanent pacemaker recipients.

The speech recognizer in general operates in noisy acoustical environments. Many research works have been done to cope with the acoustical variations. Among them, the multiple-HMM model approach seems to be quite effective compared with the conventional methods. In this paper, we consider a multiple-model approach combined with the model compensation method and investigate the necessary number of the HMM model sets through noisy speech recognition experiments. By using the data-driven Jacobian adaptation for the model compensation, the multiple-model approach with only a few model sets for each noise type could achieve comparable results with the re-training method.

This paper presents an adaptive control method based on parameter linearization for incompletely restrained wire-suspended mechanisms. The main purpose of this control method is utilizing it in a walking assist service robot for elderly people. This method is computationally simple and requires neither end-effector acceleration feedback nor inversion of estimated inertia matrix. In the proposed adaptive control law, mass, moment of inertia and external force and torque on the end-effector are considered as components of parameter adaptation vector. Nonlinear simulation for walking an elderly shows the effectiveness of the parameter adaptation law.
