A 3-year-old, intact female English cocker spaniel dog was evaluated for an acute onset of tetraplegia. Utilizing magnetic resonance (MR) imaging, the cause of the neurologic deficits was determined to be an peracute hemorrhage of spinal cord. The MR study additionally demonstrated parenchymal hyperintensity on T2weighted images and similarly located hypointensity on T1weighted images. Hemorrhagic myelomalcia was suspected based on these MR characteristics, which was subsequently confirmed histopathologically.

The prostate cancer diagnosis has traditionally been based on a systematic biopsy method in which tissue samples are randomly obtained from the prostate 10-12 sites. However, there are concerns as the method can fail to diagnose all prostate cancers or lead to over-detection of clinically insignificant cancers. MRI-guided prostate targeted biopsy has been proposed to address these shortcomings. This method involves identifying suspicious lesions using MRI and performing targeted biopsies under ultrasound or MRI guidance. We review the methods of MRI-based targeted biopsy and discuss recent guidelines and trends in prostate cancer diagnosis.

Objective: The aims of this article are to differentiate soft tissue masses showing low signal intensity on T2-weighted images (T2WIs) according to the histopathologic findings. Conclusion: To know relatively small numbered soft tissue masses with low signal intensities on T2WIs adding characteristic location, morphology, signal intensities on other sequences might be helpful for differential diagnosis of mostly non-specific soft tissue tumors on MRI.

본 연구에서는 전기/자기 및 기계적 요소들이 복합되어 이루어진 자기부상 시 스템의 설현을 위한 기초단계로서 제어동역학(controlled dynamics) 측면에 입각한 모 델식을 본드선도 기법을 이용하여 보다 조직적으로 유도한다. 우선, 자속흐름 확장 및 자속 유출량을 고려하여 부상 시스템을 모델링하고 차량/레일 및 2차 현가(second ary suspension)장치를 포함한 자기부상 시스템을 모델링한다. 다음, 지지 및 안내 방향의 동역학을 동시에 고려한 2차원 자기부상 시스템을 본드선도의 다접점 필드(mu- ltiport field) 개념을 이용하여 모델링한다. 끝으로, 본드선도 기법으로 모델링된 2차원 자기부상 시스템의 안정도와 성능을 향상시키기 위하여 LOG/LTR(linear quadra- tic Gaussian control with loop transfer recovery) 제어시스템을 설계한다. LQG/ LTR 제어방법은 Doyle과 Stein에 의해 인성(stability-robustness) 문제와 주파수역 성능을 설계시에 직접 고려할 수 있는 강력한 선형 다변수 제어시스템 설곕방법으로 현재 널리 사용되고 있다.

Recent study has demonstrated that some magnetic properties are sensitive to the microstructural state of material. The ASTM A 508 Gr. 3 reactor pressure vessel steel has various microstructural changes including martensitic and bainitic phases, and various sizes of grain and precipitates in the weld heat-affected zone (HAZ). To correlate the microstructural state with Barkhausen noise (BN), specimens were prepared through simulating various weld thermal cycles using a thermal simulator. The conventional magnetic properties, i.e. coercive force, remanence and maximum induction, did not change significantly, whereas the BN amplitude and energy during a magnetization cycle changed markedly with microstructural state. The BN increased with increasing grain and carbide sizes, and the tempered bainite structure showed higher BN parameter than tempered martensite.

This study explored the relationship between the Resilience and Organizational commitment, The police officers' perception on the resilience has been measured, and then how their perception on the resilience affects the organizational commitment has been examined. This study aimed at measuring the effects of police officers' perception on the resilience on organizational commitment By reviewing previous finding, police officers' resilience(Self-Regulation Skills(Regulation skills, Cause Analysis skills, Impulse control skills), Interpersonal Skills(Expansion skills, Communication skills, Empathy skills), Positive Capacity(Appreciate, Life satisfaction, Self-optimism)) were selected as independent variables, Organization Commitment(Affective commitment, Continuance commitment, Normative commitment) was selected as dependent variable. The result of analysis showed that Life satisfaction>Cause Analysis skills>Communication skills> Empathy skills> Appreciate> Impulse control skills influenced in Affective commitment (positive), Life satisfaction>Self-optimism>Regulation skills>Communication skills>Cause Analysis skills in Continuance commitment(positive), and Expansion skills>Empathy skills>Self-optimism>Life satisfaction>Impulse control skills in Normative commitment (positive).

Currently forest interpreter has become one of occupations, and the demand for forest interpretation has been increasing. For that reason, it is important to achieve the goal of forest interpretation and to satisfy its customers. Therefore, this research examined the relationship between organizational commitment and job motivation and analyzed the effects of job motivation on organizational commitment. Firstly, the mean value for interpreters' job motivation was classified into three factors, which were social relationship, affection for forest, and self-development. Secondly, organizational commitment was classified into two factors of goal-oriented and relation-oriented commitments. Thirdly, gender and number of participation made significance differences in job motivation. In addition, organizational commitment of interpreters was different in accordance to their age and affiliated organization. Finally, job motivation had positive impacts on organizational commitment, and especially social relationship influenced positively to general organizational commitment and goal-oriented commitment.

This study was carried out in order to verify the influence that social welfare trust organizational culture and level of empowerment. The study object 656 copies of guns were used to analysis to social worker engaged in to the community welfare agency, old man welfare agency, disabled welfare agency which was social welfare use facilities. Organizational culture and empowerment as it was for an independent variable analyzed correlation to trust and executed regression analysis to grasp a degree of an influence to be mad to trust. Research result, first, Organizational culture appeared to what I affected to trust social group culture, development cultural artist and second, Level of empowerment of social worker appeared to what I affected to trust own a task meaning result and self-determination. There's social welfare is organized in order to improve social welfare gratitude confidence, and it is group culture and development culture, and an level of empowerment to recognize a social welfare private house gives meaning anger to a task and self-determination had to heighten it.

The purpose of this study is to identify Hierarchical Culture of construction enterprises, Empowerment, and Organizational Effectiveness through empirical research. To perform this study, we carried out a survey targeting executives of construction companies in Seoul, metropolitan area, and non-metropolitan area. For analyzing, SPSS Statistical Techniques, Reliability analysis, Factor analysis, Multiple Regression analysis were used. The results of the study are as follows. First, the Hierarchy of the Culture affects significantly positive (+) on Organizational Effectiveness. Second, Hierarchical Culture affects the significantly positive (+) to the Empowerment. Third, Hierarchies and Cultural Empowerment was found to significantly affect the positive (+) on Organizational Effectiveness. Based on the conclusions, Hierarchical Culture of the domestic construction industry has a significant impact on Self-determination and the goal of consciousness among employees. In addition, this is helpful in Job Performance and Organizational Commitment.
