Conversion disorder and factitious disorder should be ruled out before making diagnosis of malingering. For this work, inspection of patient's behavior along with complete neurological examinations, psychological tests, and meticulous psychiatric interview are necessary. Facial expression test, thermography, dynamometry were failed differentiating conversion disorders to the malingered pain and motor symptoms, however, controlled diagnostic block showed positive result partly in patients with regional or cervical pain syndrome. Chronic pain patients who are related to the process of litigation encounter stressful life situations which lead them into various neurobehavioral and psychosocial complications. Most of suspected malingered patients would not revealed pure form rather mixed with factitious and/or conversion features. At the time of increasing number of chronic patients associated with traffic accidents or industrial injuries who are involved in litigation, psychiatrist are needed sharp eyes and tenacity for evaluating malingering or medically unexplained symptoms.

본 논문은 시각 장애인들의 보행 시 앞을 볼 수 없는 점을 바탕으로 시각을 음성으로 대체하여 장애 물체가 발생하였을 경우 안전을 위하여 위험 요소를 사전에 경보하여 알려주도록 구현하였다. 시각 장애인들이 보행 시 장애 물체가 나타났을 경우 이를 입체 변위 센서인 초음파 센서로 장애물의 위치를 측정하고 측정된 거리 데이터를 근거리 무선통신인 블루투스를 동하여 송 수신하여 사용자인 시각 장애인에게 소형 스피커를 통하여 음성으로 알려주고 경고함으로써 위험 요소를 사전에 대처할 수 있도록 설계를 하였다. 초음파 입체 변위 센서를 이용하여 측정된 거리를 실시간 자동 거리 측정이 가능하도록 시스템을 구현하고 이 데이터를 근거리 무선 통신으로 송 수신하며 수신 모듈이 데이터를 음성으로 전환하여 실시간 자동 경보 시스템을 구축함으로써 보행 장애 위험물 감지가 보다 효율적으로 이루어지고 디지털화되게 시스템을 개선하였다.

Purpose: The purpose of this research was to develop a scale to measure the life transition process of parents of children with autism, against the backdrop of a lack of research on this topic. Methods: Seventy preliminary items were drawn from previous qualitative research, and content validity was tested by three professors as well as three parents of children with autism. A questionnaire survey was also done between August 2011 and February 2012. Data were collected from 207 parents of children with autism and analyzed using descriptive statistics, item analysis, Cronbach's alpha, Pearson correlation coefficients, and factor analysis with the SPSS Win 15.0 program. Results: Twenty-nine items were selected to constitute the appropriate measuring scale and categorized into 5 factors explaining 63.2% of the total variance. The 5 factors were named; stages of denial (5 items), wandering (6 items), devotion (7 items), frustration (3 items), and finally acceptance (8 items). Cronbach's alpha for the 29 items was .80. Conclusion: The results of this study not only suggest assessment criteria for the life transition process of parents who have children with autism but also provide basic directions for program development to provide differentiated support and care at each stage.

Purpose: The study was done to identify the construct validity and reliability of the life transition scale (LTS) for parents who have children with autism. Methods: Exploratory factor analysis (EFA) and confirmative factor analysis (CFA) were conducted to identify the most adequate measurement model for structural validity. Convergent validity and discriminant validity were also conducted for structural validity. Data were collected from 208 parents through self-reported questionnaires and analyzed with SPSS/WIN 15.0 and AMOS 20.0 version. Results: A four factor-structure was validated (${\chi}^2$=541.23, p<.001, GFI=.82, RMSEA=.07, IFI=.89, CFI=.89, PNFI=.73, Q (${\chi}^2/df$)=2.20) at the 3rd order of EFA and CFA, and factors were named as denying, wandering, despairing, and accepting. Both convergent and determinant validity for LTS were 100%. Cronbach's alphas for the reliability of each structure were .77-.90 and .83 for total structure. Conclusion: The four structures, 24-item instrument showed satisfactory reliability and validity. LTS has the potential to be appropriate for assessing the transition process of life for parents who have children with autism and provides basic directions for differentiated support and care at each stage.

Purpose: While there are a number of studies on children with disabilities, there have been few studies on mothers of children with autism. The purpose of this study was to explore the process of life transition of mothers who have children with autism. Methods: From June 2007 to May 2009, the researcher interviewed 15 mothers of children with autism living in Seoul City, Gyeonggi or Chonbuk Provinces, and then analyzed the data gathered using the constant comparative method of grounded theory. Results: "Living together holding a string of fate" was a core category showing along the continuum of life. The basic social process of life transition encompassed 5 stages: stages of denying, wandering, devoting, mind controlling, and finally accepting. These five stages proceeded in phases, though returned back to the wandering stage occasionally. Conclusion: This study has opened the door to understanding how mothers of children with autism experienced life transition. The findings suggest that differentiated support and care at each stage should be given and there is the need to develop transition assessment tools for mothers of children with autism.

The purpose of this study was to develop the Job Functional Assessment Scale. This study was involved took third steps. First, 93 preliminary items were developed based on theoretical literature and International Classification of Functioning, Disability and Health (ICF) Model. To verify the content validity, 3 rehabilitation experts rated those items. Second, the scale consisting of 73 items was administered to sample of 880 people with disabilities. Finally, items of the scale were reduced to 58 items. Factor analysis showed evidence of construct validity of the scale. Internal consistency (Cronbach's ${\alpha}$) of total score showed .94 and Cronbach's ${\alpha}$ of 7 subfactor demonstrated .74~.90. Thus, Job Functional Assessment Scale demonstrated satisfactory convergent validity and discriminant validity. In addition, the practical use of the scale was discussed.

This research reviewed the instrumental ADL for patients with mild cognitive impairment, which is one of the most interested topics, and hope that this research helps evaluating and treating the mid cognitive impairment patients in occupational therapy. The treatment for dementia patients are actively in progress, but there has not been treatment approach about mild cognitive impairment patients, who are in risk of moving on to dementia. In this review, we have dealt with the foundation of matching the point to instrumental ADL from the occupational areas of mild cognitive impairment patients and normal elders. We have discussed the that essential consideration about instrumental ADL is needed to prevent mild cognitive impairment developing into dementia. In conclusion, there is a need of regular evaluation about instrumental ADL considering the occupational areas of mild cognitive impairment patient groups, who are highly in risk of developing into dementia, and occupational therapeutic approach is needed as well.

This study compared voice range profiles (VRPs) of modal and falsetto register in 53 dysphonic and 53 non-dysphonic adult women with gliding vowel /a/'. The results shows that maximum fundamental frequency (F0_MAX), maximum intensity (I_MAX), F0 range (F0_RANGE), and intensity range (I_RANGE) are lower in the dysphonic group than in the non-dysphonic group. F0_MAX and F0_RANGE are significantly higher in falsetto register than modal register in both groups. I_MAX and I_RANGE are significantly higher in falsetto register in the non-dysphonic group, but those are not different between two registers in the dysphonic group. There was no statistically significant difference in minimum F0 (F0_MIN) and minimum intensity (I_MIN) between the two groups. Modal-falsetto register transition occurred at 378.86 Hz (F4#) in the dysphonic group and 557.79 Hz (C5#) in the non-dysphonic group, which was significantly lower in the dysphonic group. It can be seen that both modal and falsetto registers in dysphonic adult women are reduced compared to non-dysphoinc adult women, indicating that the vocal folds of dysphonic adult women are not easy to vibrate in high pitches. The results of this study would be the basic data for understanding the acoustic features of voice disorders.

In this thesis, the effect of switch maintenance improvement is confirmed after testing and operating the switch monitoring system that were researched and developed originally in order to improve method of electric switch maintenance. However, as in an automatic interlocking station where a ground crew was not placed, repair and inspection could not be carried out until the maintenance person comes in case of switch problems or maintenance. In order to improve this issue, control module was installed in a monitoring system which can communicate through a data radio to a remote computer. Thus, the monitoring device can receive control information which a remote computer commands during the operation of switches. Afterward, it shows information on the real-time status of swith, in particular, anomaly situation through user interface after the switch is operated. By improving performance of the monitoring system in this way which can be managed and controled at a remote place, the prompt countermeasure system in case of disruption will be built and as a result, efficiency and convenience of maintenance improvement will be expected to increase.
