A new dressing technique with utilizes electrolytic phenomenon for realizing effective mirror surface grindings with metal bonded super-abrasive wheels is called “Electrolytic In-process Dressing Grinding”. This technique enabled metal bonded micro-grain wheels, such as micro-grain cast iron fiber bonded wheels, to be used for mirror surface finish processes effectively. But this technique requires a lot of knowledge and experience to perform. And the condition of dressing is variable according to the time. Therefore adaptation of Monitoring and Control technique is needed.

The paper describes the adaptation of evolutionary fuzzy model ins (EFM) in developing global function approximation tools for use in genetic algorithm based optimization of nonlinear structural systems. EFM is an optimization process to determine the fuzzy membership parameters for constructing global approximation model in a case where the training data are not sufficiently provided or uncertain information is included in design process. The paper presents the performance of EFM in terms of numbers of fuzzy rules and training data, and then explores the EFM based sizing of automotive component for passenger protection.

The goal of our research is to build a text-independent speaker identification system that can be used in any condition without any additional adaptation process. The performance of speaker recognition systems can be severely degraded in some unknown mismatched microphone and noise conditions. In this paper, we show that PCA(principal component analysis) can improve the performance in the situation. We also propose an augmented PCA process, which augments class discriminative information to the original feature vectors before PCA transformation and selects the best direction for each pair of highly confusable speakers. The proposed method reduced the relative recognition error by 21%.

The purpose of this study was to investigate the changes of lives and problems of 'Kirogi'(or Wild Goose) fathers, who were called fathers in the 'Kirogi' families, South Korean families separated by an ocean. They almost sent too much money that were $50-100\%$ of their family income to the families abroad, and got economic pressures so severely. More or less, they sold their own real estates, moved to much smaller sized house. and often expended the saving money. Also, they had difficulties of taking care of their children and felt lonely very much. By the hand, they might experience the adaptation process through 3 stages-troubles, acception(or wandering or enjoy), adjust (or violation). They had three types of problems, that is, family relationship problem(the isolation), psychological problem(loneliness and self-control), economic problem (financial pressure and drop of economic status). They found the strategies to overcome these problems for themselves. Firstly, they took lots of methods like email, internet chatting, phone, etc. to communicate with their family everyday and made many events to strengthen the ties among families. Secondly, they got rid of stresses mainly by joining with their colleagues at work. Finally, they decided to lower the standard of living of their family in foreign country or tried to find their wives' jobs to prevent the financial hardship.

This article introduces the five functions of the national innovation system(NIS). As one of social systems in the national level, the five generic functions of open system - production, boundary spanning, maintenance, adaptation, management functions - are applied to the NIS. The production function is the primary process, which produces innovative products and services of the NIS. The boundary spanning function is the function of procuring input and disposing the innovation output or aiding in these processes. Experienced R&D human resources, R&D funds, technology etc. are some of the components of the input of the NIS. The maintenance function is responsible for maintaining smooth operation and upkeeping the system in terms of various conditions. The adaptation function is to help the system change and adapt, and scan the environment for problems, opportunites, and technological developments. It has outward orientation, from the long-term view for the survival of the system. The management function carries out planning and control of the overall activities for the other four functions in order to effectiving run the system as a whole. Finally, this article discusses implications of the diagnosis of the national innovation system and the decision making process of S&T policy.

Purpose: The study was done to explore meanings and essence of the experience in South Korea of men defectors from North Korea. Methods: Data were collected from March, 2011 to May, 2012, through in-depth interviews with ten men defectors. Data analysis was conducted using the process of hermeneutic phenomenological reflection. Results: Eight essential themes were extracted; 'buoyant expectation for a new life', 'feeling guilty about family left behind in North Korea', 'inability to become acclimatized due to communication difficulties', 'inability to socialize with South Koreans due to different lifestyles', 'finding strength through trustworthy acquaintances', 'continuing reconciliation with oneself while trying to assimilate into South Korean culture', 'self-realization of one's original self', and 'continuing to feel out the possibility of a future in South Korea'. Conclusion: The findings indicate that North Korean men who defect to South Korea shape their identity through three phases: forming self-image during escape from North Korea, trying to become accustomed to South Korean society, and finding their own identity by self-realization of their original self. Eventually, the whole process enables them to recover their identity, to feel a sense of belonging, and to discover possibilities for a better future.

In this paper, an adaptive algorithm is proposed in streaming MPEG-4 contents with fluctuating resource amount such as throughput of network conditions. In the area of adaptive streaming issue, a lot of researches have been made on how to represent encoded media(such as video) bitstream in scalable way. By contrast, MPEG-4 supports object-based multimedia content which is composed of various types of media streams such as audio, video, image and other graphical elements. Thus, it can be more effective to provide individual media streams in scalable way for streaming object-based content to heterogeneous environment. The proposed method provides the multiple media streams corresponding to an object with different qualities and bit rate in order to support object based scalability to the MPEG-4 content. In addition, an optimal selection of the multiple streams for each object to meet a given constraint is proposed. The selection process is adopted a multiple choice knapsack problem with multi-step selection for the MPEG-4 objects with different scalability levels. The proposed algorithm enforces the optimal selection process to maintain the perceptual qualities of more important objects at the best effort. The experimental results show that the set of selected media stream for presenting objects meets a current transmission condition with more high perceptual quality.

The purpose of this study is to offer suggestions to help immigrated youths of multicultural families become successful members of Korean society while preparing to enter schools or becoming involved in social activities. The study examined the following three issues using grounded theory: (1) the characteristics of cultural adaptation for immigrated youths of multi-cultural families; (2) their acculturation processes; and (3) their different patterns of acculturation experience. The process of acculturation involves (1) feeling timid, (2) feeling regretful and angry, (3) looking around and making an attempt, (4) feeling difficulty and feeling left out, (5) accepting reality and seeing Korea in a positive light. The core of acculturation among the immigrated youths of multicultural families is a limited living in an unfamiliar culture. Five acculturation patterns were found in the current study: (1) Someone who is actively striving for future dreams; (2) someone who adjusts himself/herself to circumstances without plans; (3) someone who passively makes an effort; (4) someone who accepts reality to continue education; and (5) someone who temporarily stays for financial reasons.

Purpose: The purpose of this study was to identify the role experience of preceptor nurses in general hospitals. Methods: Data were collected from 10 experienced preceptor nurses through in-depth interviews about their experiences. The main question was "How do you describe your experience as a preceptor in the process of role adaptation?" Qualitative data from field and transcribed notes were analyzed using Strauss & Corbin's grounded theory methodology. Results: The core category of experience in the process of role adaptation as a preceptor nurse was identified as 'being responsible to teach from beginning to end'. The participants identified five interactional strategies; 'abruptly having to take the role as a preceptor unwilling', 'difficulties in field training with variable situations', 'preceptor and new nurse with love and hate relationships', 'bring up preceptee as a child', 'redefining the concept of preceptor'. Conclusion: The results of this study provide useful information for understanding the role of preceptor nurses in general hospital who have to teach new nurses with patience and responsibility. It will be needed to establishment of preceptor's role and educational standards, and policy for their rewards by nurse manager. Additionally, making cooperative educational climate in nursing ward is important for teaching new nurse.
