Woojae Han,Minki Hong,Taeoh Kim,Sihun Park 한국청각언어재활학회 2020 Audiology and Speech Research Vol.16 No.2

Purpose: The purpose of this study was to compare change in the perception of hearing impairment before and after the handicap experience and to qualitatively analyze accepting attitude and change toward the impairment in college students. Methods: Twenty college students were asked to wear personalized earplugs on their ears to experience the handicap of hearing loss for five days. They reported 12-items questionnaire before and after the experience and had also 1:1 individual interview using a structured format with open questions. Results: Although the negative attitude toward the hearing impairment (78.30%) was high enough before the handicap experience, the positive attitude (78.02%) was prominent after the experience. Further, the participants had expressed negative feeling such as guilt and avoidance toward the hearing impairment before the experience, while showing discrepancies between their cognition and behaviors. However, their perception and attitude were changed with positive recognition after the experience. Conclusion: Although it was a short period of the experience, the present results confirmed that the non-disabled students had an internal understanding and distracted negative attitudes toward the hearing impairment. The systematic and detailed handicap experiences might be expected to maintain a positive attitude toward the students with disabilities for a while.

Pole-Zero Fitting for Transfer Function of Hearing-Aid Receiver: Evidence-Based Review

Han, Woojae,Kim, Noori The Korean Audiological Society and Korean Otologi 2018 Journal of Audiology & Otology Vol.22 No.3

<P>The hearing-aid transducer is ubiquitous in the hearing-aid industry. For example, the balanced armature receiver (BAR), first invented by A.G. Bell, has been used in all telephone earphones because it has the highest output and best frequency response. Nevertheless, previous electro-mechanical studies on these miniature speakers are quite primitive, given the price of the transducers. Thus, more detailed analysis is critically important for the field of hearing science. This review study was motivated by Hunt’s parameter calibration (1954), a widely used commercial hearing-aid receiver (ED series, manufactured by Knowles Electronics, Inc.). In the body of the study, the transfer function of the BAR system (i.e., pressure over voltage) was calculated from Hunt’s parameters, solely from the electrical terminals of the device. The computed transfer function was then further investigated by comparing to the pole-zero fitting method using the methods of Gustavsen and Semlyen (1999) and Prony (1975). Based on our short experiment, the better fitting result was achieved with Gustavsen and Semlyen’s method. By decomposing results of the transfer function fitting into all-pass and minimum-phase parts, the system was confirmed as a delay system. We conclude that the BAR system is linear, time-invariant, stable, and causal while providing an evidence-based understanding of the hearing-aid receiver system.</P>

Does vegetation matter for the criminal behavior among people with serious mental illness?

Han Woojae,Marzell Miesha,Deng Chengbin 한국사회복지학회 2020 Asian Social Work and Policy Review Vol.14 No.1

This study attempts to examine the effect of vegetation on arrests of offenders with and without serious mental illness (SMI). Data from the MacArthur mental health court study were analyzed. Objective arrest data were obtained 12–18 months preand post‐court involvement between 2005 and 2007. Vegetation data were captured by the normalized difference vegetation index, which can be regarded as a general measure of “vegetation” and linked with GeoID, obtained from the American Community Survey. We analyzed data of sociodemographic factors (e.g., age, gender), crime‐related factors (e.g., age of first arrest), and vegetation in related to the crime on 652 offenders with mental illness. Multilevel negative binomial regression revealed no significant effect of vegetation on arrests among offenders without SMI; however, for those with SMI, a significant variation in vegetation on arrests was found among all study models. Our findings suggest that vegetation is significantly associated with arrests, with a positive effect on reducing the recidivism only among offenders with SMI. Given that practice and policy almost exclusively focus on individual factors of crimes, it is important to have more considerations about how neighborhood factors affect criminal behavior, depending on SMI in order to have more comprehensive methods of crime prevention.

한우재(Han, Woojae),대수민(Dae, Soomin) 한국정신건강사회복지학회 2022 정신보건과 사회사업 Vol.50 No.2

정신질환 범죄자는 꾸준히 그 수가 증가하고 있으며 이들의 재범률은 일반 범죄자에 비해서 높다. 또한, 정신질환 범죄자 중 강력범죄의 비율은 일반 범죄자의 비율보다 5배 이상 높은 것으로 나타났다. 기존 처벌을 중심으로 한 정신질환 범죄자 처우의 효과성에 의문이 제기되면서, 2016년부터 대안적인 사법형태의 하나인 치료명령 제도가 시작되었다. 제도 시행 6년째가 되었지만, 아직까지 치료명령제도의 효과성에 관한 실증적인 연구는 부족한 상황이다. 본 연구의 목적은 치료명령 제도운영의 효과성 및 개선방안을 도출하여, 실효적인 제도의 형성이나 효과적인 운영을 위한 기초자료를 제공하는 것이다. 이를 위해서 본 연구는 보호관찰소에서 치료명령을 담당하는 실무자 중 경험과 지식이 풍부한 보호관찰관을 대상으로 초점집단면접을 진행하였다. 분석결과, 본 연구에서는 ‘목적에 부합하는 운영’, ‘참여자의 특성을 반영한 치료명령’, ‘실무자를 위한 지속 가능한 업무환경조성’, ‘정신질환 범죄자를 위한 체계적인 접근’ 등 4개의 하위주제가 도출되었다. 연구 결과를 바탕으로 정신질환 범죄자를 대상으로 하는 치료명령제도의 효과적인 운영을 위한 실천적 · 정책적 함의를 논하였다. The number of offenders with mental illness is steadily increasing, and their recidivism rate is higher compared to offenders without mental illness. In addition, the rate of severe crime by mentally ill offenders was five times higher than general criminals. As questions were raised about the effectiveness of the current punishment-centered approach for offenders with mental illness, the treatment order started as an alternative criminal justice system in 2016. While it has been only 5 years, there is lack of empirical studies about the treatment order. The purpose of this study is to evaluate the effectiveness of the treatment order and provide the alternatives for better operation by conducting in-depth interviews with probation officers in charge of treatment orders. As a result of the analysis, in this study, four sub-themes were derived: Operation suited to the purpose, Treatment order by participants’ characteristics, Providing sustainable work environment for practitioners, and Systematic approach for offenders with mental illness. Based on the research results, policy and practical implications for the effective operation of the treatment order for offenders with mental illness were discussed.

정신질환 범죄자의 지역사회통합에 대한 소고

한우재(Han, Woojae),백세현(Baek, Sehyun),이성규(Lee, Sungkyu) 한국교정복지학회 2022 교정복지연구 Vol.- No.77

정신질환 범죄자의 지속적인 증가와 높은 재범율로 인해 현행 정신질환 범죄자를 대상으로 한 시설 내 처우의 효과성에 의문이 제기되고 있다. 또한, 정신질환과 범죄라는 복합적인 문제에 대해서 형벌중심의 개입이 아닌 치료중심의 다양한 접근들이 시도되고 있다. 특히, 정신질환 범죄자의 성공적인 재활을 위해 지역사회통합의 개념이 점차 강조되고 있는 상황이다. 하지만 선행연구는 정신질환 범죄자의 처우와 관련하여 치료와 지역사회통합을 이론적 개념적으로만 다룰 뿐, 기본 원칙이나 사례연구를 통해 종합적으로 다루지 못한 한계를 가지고 있다. 이에 본 연구에서는 정신질환 범죄자의 성공적인 재활을 위해 다차원적인 지역사회통합에 대해 논의하고자 하였다. 또한, 해외사례를 바탕으로 정신질환 범죄자의 성공적인 지역사회 재활을 위한 구체적인 방안을 제공하고자 하였다. 이를 위해서 본 연구는 국내 정신질환 범죄자 처우 현황 및 문제점과 지역사회 통합의 다차원적 개념에 대해서 논하였다. 또한, 해외 사례 분석을 통해서 지역사회 통합을 위한 8가지 원칙을 제시하였고, 실제 지역사회 기관 및 교정시설에서 제공하는 프로그램들을 소개하였다. 마지막으로 정신질환 범죄자의 성공적인 지역사회 통합을 위한 과제에 대해 논하였다. An increase and high recidivism rate among offenders with mental illness bring the questions about the effectiveness of institution-centered approach. In addition, there are is various approaches focusing on treatment rather than punishment to deal with complicated issues related crime and mental illness. In particular, the concept of community integration has been emphasized for the successful rehabilitation of offenders with mental illness. However, previous studies only treated this issue in a theoretical and conceptual way without comprehensive understanding using critical principles and practical examples. This study aimed to discuss multidimensional community integration for the successful rehabilitation of offenders with mental illness. Further, we suggested specific and applicable solutions for successful community rehabilitation by introducing examples of other countries. This study discussed the statistics, problems of current approaches for offenders with mental illness in Korea, and the multidimensional concept of community integration. We also provided 8 principles for community integration based on the analysis of foreign case study and introduced various programs in correctional facilities and community agencies. Last, we discussed about tasks for successful community integration of offenders with mental illness.

경찰의 정신질환자 경험과 인식이 소진에 미치는 영향

한우재(Han, Woojae),김나영(Kim, Nayoung) 한국정신건강사회복지학회 2023 정신보건과 사회사업 Vol.51 No.3

지역사회 내 정신질환 범죄자 수는 지속해서 늘고 있으며, 지역사회의 문지기(Gate Keeper)로서 경찰의 역할을 매우 중요하다. 하지만 정신질환자를 대하는 경찰을 대상으로 한 실증적인 연구는 부족한 상황이다. 본 연구는 경찰의 정신질환자와의 경험(접촉 빈도, 폭력 경험)이나 인식(태도, 어려움, 자신감)을 알아보고, 이러한 것들이 경찰의 관련 업무의 소진에 미치는 영향을 살펴보았다. 205명의 경찰을 대상으로 설문을 진행하였으며, 경험이나 인식이 소진에 미치는 영향은 회귀분석을 통해 살펴보았다. 연구 결과, 지구대나 파출소에 근무하는 경우 정신질환자와의 접촉의 빈도가 매우 높고(평균 월 1회에서 2~3회 사이), 폭력피해 경험 또한 평균 월 1회에 달하는 것으로 나타났다. 또한, 응답자 대부분은 정신질환자 관련 업무에 대해서 부정적인 태도를 보이고, 대처에도 어려움을 겪고 있었다. 마지막으로 경찰의 정신질환자 관련 업무의 소진에 있어서 부정적 태도, 대처의 어려움, 자신감 등이 유의미한 영향을 미치고 있었다. 연구 결과를 바탕으로 실천적 정책적 함의를 논의하였다. The number of offenders with mental illness in the community continues to grow, and the role of the police as gatekeepers in the community is critical. However, there are few empirical studies on police officers working with people with mental illness. This study aimed to explore the experiences (number of contacts and incidents of violence) and perceptions (attitudes, difficulties, confidence) of police officers regarding individuals with mental illness, as well as to examine the effects of these factors on officer burnout. A questionnaire was conducted with 205 police officers, and the impact of their experiences and perceptions on burnout was investigated through regression analysis. The results showed that police officers have a high frequency of contact with people with mental illness, averaging between 1 to 2 to 3 times a month. Furthermore, they reported experiencing violence, on average, once a month. Additionally, the majority of respondents displayed a negative attitude and encountered difficulties when dealing with individuals with mental illness. Lastly, negative attitudes, work difficulties, and self-confidence related to working with people with mental illness significantly influenced police officer burnout. Practice and policy implications were discussed.

정신질환 범죄자를 대하는 경찰의 경험에 관한 연구 -초점집단면접을 중심으로-

한우재 ( Han Woojae ),대수민 ( Dae Su-min ),박지형 ( Park Ji-hyung ) 한국가족사회복지학회 2022 한국가족복지학 Vol.69 No.2

정신질환 범죄자의 수는 날로 증가하고 있으며 일반 범죄자보다 이들의 재범률은 매우 높은 편이다. 또한, 정신질환 범죄자의 강력범죄 비율은 전체 범죄자와 비교하면 5배 정도 높다. 자연스레 정신질환자의 지역사회 내 사건에 대한 경찰의 개입은 늘고 있으나, 대부분 연구는 관련 이론이나 해외사례를 소개하는 것에 그치고 있다. 특히, 일선에서 정신질환자들을 대하는 경찰에 관한 실증적인 연구는 부족한 실정이다. 따라서 본 연구에서는 지구대에서 근무하는 경찰을 대상으로 초점집단면접을 실시하여 경찰의 정신질환자에 대한 경험을 다양한 차원에서 분석하고자 하였다. 이를 위해 2021년 5월 지구대에 근무하는 경찰 3명을 대상으로 초점집단 면접을 진행하였다. 분석 결과, 본 연구에서는 ‘미숙함과 복합적인 감정’, ‘예정된 실패와 상처’, ‘체계적인 접근 및 협력의 한계’ 등 3개의 하위주제가 도출되었다. 본 연구결과를 바탕으로 지역사회 정신질환자를 대한 경찰을 위한 정책적·실천적 함의를 논하였다. There is increasing number of offenders with mental illness in the community, and their recidivism rate is relatively high compared to general offenders In addition, the felony crime rate of mentally ill offenders is approximately five times higher than that of all offenders. While police intervention for offenders with mental illness is increasing, previous studies only provided theories and case studies from other countries. In particular, there is a lack of empirical research on the police who encounter people with mental illness on the front lines. Thus, this study aims to conduct the focus group interview to further investigate the experience of the police with mentally ill offenders in various dimensions. As a result of the analysis, three sub-themes were derived in this study: ‘immaturity and complex emotions’, ‘predicted failures and stress’, and ‘systematic approach and cooperation’. Based on the results of this study, the policy and practical implications was discussed for the police to work with offender with mental illness.
