This study is a narrative depiction of a focusing attitude training experience through a counselor's participation in focusing workshop. Through the story of life, the researchers explored how the participant experienced according to the three - dimensional narrative inquiry space (time, place, interaction). The results of this study is that the contact (self - awareness process) with self - experience through focusing training abled the counselor to facilitate clients' own self-contact during the psychotherapy process and as a result the counselor was able to establish 'relational depth' with clients. Through Focusing experience, the counselor was able to aware bodily feeling 'as it is' which helped the expansion of self with multiple perspectives of life away from fixed own self -frame. The implication of this study is to explore the meaning of the counselor's Focusing attitude and to prepare for the development of Focusing workshops in the future.

Researches using time reversal acoustics(TRA) for impact localization have been paid attention to recently. Dispersion characteristics of Lamb waves, which restrict the utility of classical nondestructive evaluation based on time-of-flight information, can be compensated through the application of TRA to Lamb waves on a plate. This study investigates the spatial focusing performance of time reversal Lamb waves on a plate using finite element analysis. In particular, the virtual sensor effect caused by multiple wave reflections at the boundaries of a plate is shown to enable the spatial focusing of Lamb waves though a very small number of surface-bonded piezoelectric(PZT) sensors are available. The time window size of forward response signals, are normalized with respect to the number of virtual active sensors. Then their effects on the spatial focusing performance of Lamb waves are investigated.

자체집광(Self-focusing)현상은 매우 높은 집적도를 가지는 광기록매체의 제작에 응용 가능하기 때문에 많은 연구자들에 의해 광범위하게 연구되어왔다. 그동안의 연구에서는 자체집광에 대한 분석방법으로서 빛살의 벡터특성을 무시한 비선형 슈뢰딩거 방정식(nonlinear Schr dinger equation)을 이용하였는데, 이 경우 축상으로 대칭적인 빛살이 입사될 때 발생되는 다중 필라멘테이션(Multiple Filamentation)현상은 입사빛살에 첨가되는 random noise에 기인한다는 것이 유일한 해석방법이었다.

This study examined the relationship between ambivalence of Korean working mothers for children and their future desire for child birth. This study examined multiple-role efficacy as a mediator in the relationship between ambivalence for their children and future desire for child birth by Korean working mothers having more than one pre-school aged child. This study examined the mediation effect of multiple-role efficacy on the relationship between ambivalence and desire for child birth by working mothers. On-line and off-line survey data from 291 Korean working mothers with more than one pre-school aged child was used for this study. Collected data were analyzed using the PASW 18.0 program and descriptive statistics analyses. Structural equation modeling and bootstrapping were conducted by AMOS 20.0 program. Results showed that ambivalence for children of working mothers having pre-school aged children had no direct influence on future child birth desire. However, their ambivalence had an indirect influence on future child birth desire through multiple-role efficacy and multiple-role efficacy by working mothers had significant effect on child birth desire. In conclusion, the working mothers' multiple-role efficacy had a mediation influence on the relationship between ambivalence for children and desire of child birth. These results were discussed for designing a policy to counter low birth.

The multiple entity data model which contains metadata that associate two or more entities is applied recordkeeping metadata standard in recent years. This paper described and analyzed the recordkeeping metadata standard applying multiple entities such as ISO 23081, Australia recordkeeping metadata Standard, New Zealand recordkeeping metadata Standard, New South Wales recordkeeping metadata Standard, Queensland recordkeeping metadata Standard recordkeeping metadata Standard, South Australia recordkeeping metadata Standard, focusing on scope, the number of entities, category in entity, metadata elements. And shows some examples of relationship entity which is the key of multiple entity. As a result of the analysis, this paper suggests some consideration when recordkeeping metadata standard applying multiple entities is revised.

Although synthetic aperture focusing techniques can improve the spatial resolution of ultrasound imaging, they have not been employed in a commercial product because they require a real-time N-channel beamformer with a tremendously increased hardware complexity for simultaneous beamforming along M multiple lines. In this paper, a hardware-efficient beamformer architecture for synthetic aperture focusing is presented. In contrast to the straightforward design using NM delay calculators, the proposed method utilizes only M delay calculators by sharing the same values among the focusing delays which should be calculated at the same time between the N channels for all imaging points along the M scan lines. In general, synthetic aperture beamforming requires M 2-port memories. In the proposed beamformer, the input data for each channel is first upsampled with a 4-fold interpolator and each polyphase component of the interpolator output is stored into a 2-port memory separately, requiring 4M 2-port memories for each channel. By properly limiting the area formed with the synthetic aperture focusing, the input memory buffer can be implemented with only 4 2-port memories and one short multi-port memory.

A new method for simultaneous multiple transmit focusing using orthogonal weighted FM chirp is proposed. Weighted chirp signals focused at different depths are transmitted at the same time. These chirp signals are mutually orthogonal in the approximate sense that the autocorrelation function of each signal has a narrow mainlobe width and low sidelobe levels, and the crosscorrellation function of any pair of the signals has smaller values than the sidelobe levels of each autocorrelation function. This means that each weighted chirp signal can be separately compressed into a short pulse, focused individually and combined with other focused beams to form a frame of image. Theoretically, any two chirp signals defined in two nonoverlapped frequency bands are mutually orthogonal. In the present work, however, a fractional overlap of adjacent frequency bands, by up to 25%, were permitted to design more chirp signals within a given transducer bandwidth. The crosscorrelation values due to the frequency overlap could be reduced by alternating the direction of frequency sweep of the adjacent chirp signals. The simulation results show that this method can improve the lateral resolution of image without sacrifice in the frame rate compared with the conventional pulse system.

The purpose of this study is to the relation between the focusing manner and clinical competence and to determine the effect of the focusing manner on clinical competence. In December 2018, data were collected from 189 university students in the nursing department and analyzed using a multiple regression. As a result, major satisfaction and focusing manner of nursing university students were identified as major factors influencing clinical competence. In particular, 'expressing', a sub-factor of the focusing manner, had a significant effect on the sub-factors of clinical competence ability, 'nursing process, nursing skill, teaching and cooperation, interpersonal relationships and communication, and professional development', and explanatory power was 15.7%~19.9%. Therefore, during the undergraduate course, it is suggested that university students in the nursing department actively develop teaching-learning methods along with the development of a program to improve 'the ability to express appropriately for the situation'.
