발달장애 청소년의 문제행동 감소를 위한 집단미술치료 사례
박창범(Park Chang Bum) 한국통합예술심신치유학회 2017 통합심신치유연구 Vol.4 No.2
본 연구는 장애인주간보호시설을 이용하는 발달장애 청소년에게 집단미술치료 프로그램을 실시하여 문제행동 개선에 어떠한 영향을 미치는지 알아보는 것이다. 사례집단은 2명의 여자와 2명의 남자로 특수학교와 일반학교에 재학중인 지적장애 2, 3급의 발달장애 청소년으로 주의력과 관계성, 공격성의 문제행동이 있는 총 4명으로 구성하였으며, 연령은 15세부터 21세까지이다. 프로그램은 2017년 1월부터 3월까지 매 주 2회기씩 50분으로 총 12회기를 진행하였으며, 선행연구를 통하여 초기 3회기, 중기 6회기, 후기 3회기로 구성하였다. 프로그램의 효과성 분석은 행동상의 문제를 연구자와 사회재활교사와의 상담을 통해서 선정된 주의력, 관계성, 공격성의 차이를 시설의 종사자들에게 행동관찰 기록지를 통해 사전과 사후를 검사하여 비교하였으며 회기별 변화를 기술하였다. 또한 양적 데이터로는 사례수는 적지만 사전, 사후 t검정을 통해 비교하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 주의력이 향상되었다. 둘째, 동료들 간 관계성이 향상되었다. 셋째, 동료를 때리거나 물건을 파손하는 등의 공격성이 감소되었다. 따라서 발달장애 청소년들에게 실시한 집단미술치료 프로그램은 문제행동의 개선에 긍정적인 영향을 미치는 것을 알 수 있었다. This study was to identify how group art therapy has effect on improving problem behavior of adolescents with developmental disabilities who used a daycare center for disabilities. The subjects for this case study were 2 females and 2 males, who were aged from 15 to 21 and attended to special-education school and general school. They were 2nd and 3rd class intellectual disabilities having problem behavior with attentiveness, relationship and aggression. With preceding research, a total of 12 sessions of the program consisted of 3 session of early stage, 6 sessions of mid stage and 3 sessions of latter stage and was carried out 2 sessions a week for 50 minutes. For the effectiveness analysis of the program, the staffs in the center had carried out pre and post test with the behavioral observation recording card and then the change rate that selected by consultation between researcher and social rehabilitation teacher were compared and described the sessional change. Furthermore, pre and post t-test was used although it was small cases as quantitative data. The main results are as follows. First, the attentiveness increased. Second, relationship with other people increased. Third, there was decrease in aggression which is hitting people or throwing stuffs. Therefore, it was showed that the group art therapy conducting with adolescents with developmental disabilities had a positive effect on improving problem behavior.

생체 신호 측정용 저 잡음 저 전력 용량성 계측 증폭기
박창범,정준모,임신일,Park, Chang-Bum,Jung, Jun-Mo,Lim, Shin-Il 한국센서학회 2017 센서학회지 Vol.26 No.5
We present a precision instrument amplifier (IA) designed for bio-potential acquisition. The proposed IA employs a capacitively coupled instrument amplifier (CCIA) structure to achieve a rail-to-rail input common-mode range and low gain error. A positive feedback loop is applied to boost the input impedance. Also, DC servo loop (DSL) with pseudo resistors is adopted to suppress electrode offset for bio-potential sensing. The proposed amplifier was designed in a $0.18{\mu}m$ CMOS technology with 1.8V supply voltage. Simulation results show the integrated noise of $1.276{\mu}Vrms$ in a frequency range from 0.01 Hz to 1 KHz, 65dB SNR, 118dB CMRR, and $58M{\Omega}$ input impedance respectively. The total current of IA is $38{\mu}A$. It occupies $740{\mu}m$ by $1300{\mu}m$ including the passive on-chip low pass filter.

CMOS 소자로만 구성된 1V 이하 저전압 저전력 기준전압 발생기
박창범(Park, Chang-Bum),임신일(Lim, Shin-Il) 한국전기전자학회 2016 전기전자학회논문지 Vol.20 No.2
본 논문에서는 저항과 BJT를 사용하지 않고 sub-threshold 영역에서 동작하는 저전압, 저전력 기준전압 발생기를 설계하였다. CTAT 전압 발생기는 두 개의 NMOS 트랜지스터를 이용하여 구성하였고, 충분한 영역의 CTAT 전압을 발생시키기 위해 바디 바이어스 회로를 이용하였다. PTAT 전압 발생기는 PTAT 전압을 생성하기 위해 MOS 트랜지스터 입력 쌍의 서로 다른 사이즈 비를 이용하는 차동증폭기 형태로 구성하였다. 제안한 회로는 0.18-㎛ 표준 CMOS 공정으로 설계되었다. 시뮬레이션 결과로 290mV의 출력 기준 전압을 가지며, -20˚C 에서 120˚C의 온도 변화에서 92 ppm/˚C의 전압 변화 지수와 전원전압 0.63V에서 15.7nW의 소모 전력을 갖는 것을 확인하였다. In this paper, we present a nanopower CMOS bandgap voltage reference working in sub-threshold region without resisters and bipolar junction transistors (BJT). Complimentary to absolute temperature (CTAT) voltage generator was realized by using two n-MOSFET pair with body bias circuit to make a sufficient amount of CTAT voltage. Proportional to absolute temperature (PTAT) voltage was generated from differential amplifier by using different aspect ratio of input MOSFET pair. The proposed circuits eliminate the use of resisters and BJTs for the operation in a sub-1V low supply voltage and for small die area. The circuits are implemented in 0.18um standard CMOS process. The simulation results show that the proposed sub-BGR generates a reference voltage of 290mV, obtaining temperature coefficient of 92 ppm/˚C in -20 to 120˚C temperature range. The circuits consume 15.7nW at 0.63V supply.

Formalin이 넙치(Paralichthys olivaceus) 난 발생 및 부화자어에 미치는 영향
박창범(Chang Bum Park 외 14명),나오수,이치훈,김병호,이영돈,허문수,이정재,정상철,이기완,노 섬,송춘복,최광식,이제희,여인규,전유진 환경독성보건학회 2002 환경독성보건학회지 Vol.17 No.1
Effects of formalin treatment on embryogenesis and larvae growing in fertilized eggs and hatched larvae of olive flounder, Paralichthys olivaceus were investigated. Fertilized eggs and hatched larvae were exposed to aqueous solution with 100, 200, 400, 800 and 1,000 ppm of nominal formalin concentration. They were kept in sea water of 16, 18 and 22℃, respectively. Surviva] rate and hatchability of fertilized eggs were high in control groups more than formalin treated groups in 16, 18 and 22℃, respectively (P<0.05). A similar effect that survival rate of hatched larvae was also observed for control and treatment groups. On the other hand, fertilized eggs treated with 400ppm formalin, were all death in kept in 22℃. These results suggest that high-dose of formalin in fertilized eggs and hatched larvae in olive flounder, Paralichthys olivaceus was inhibited the normal embryogenesis for fertilized eggs and growing for hatched larvae. Also, these inhibited effects was promoted in higher temperature.

박창범 ( Park Chang-bum ),최관호 ( Choi Gwan Ho ) 민주주의법학연구회 2018 민주법학 Vol.0 No.67
2010년에 제정되어 2011년부터 시행되고 있는 “성충동 약물치료법” (Chemical Castration)은 성범죄자의 성욕을 억제시켜서 재범을 방지하고자 도입된 보안처분의 일종이다. 그러나 현재의 성충동 약물치료법은 성범죄자의 동의 없이 검사의 청구와 법원의 판결로 시행될 수 있다는 강제성 때문에 자기결정권의 기본권을 침해한다는 문제가 있다. 그 외에도 성충동 약물치료 판단 시점의 문제, 사용되는 약물로 인한 부작용 가능성 등이 문제점으로 제시되고 있다. 하지만 현재까지 이 치료가 성범죄자의 재범방지에 정말로 효과적인지에 대한 논의는 거의 없었다. 따라서 이 연구에서는 성충동 약물치료의 규범적인 정당성 외에도 의학적으로도 과연 성충동 약물치료가 성범죄자의 재범방지에 효과적인지에 대한 근거를 확인하기 위하여 현재까지 발표된 국내 및 외국의 임상연구들을 검토하였다. 이와 더불어 법령과 시행령의 문제점도 살펴보았다. 결론적으로 성충동 약물치료가 성범죄자의 재범방지에 효과적인지 과학적 근거가 상당히 미약하여 명확히 결론 내기 어려운 반면에 약물치료와 관련된 부작용은 약물치료 대상자들에서 상당수 발생함을 확인할 수 있었다. 이런 논증 과정을 통해서 성충동 약물치료가 법상 요건을 결하였음을 확인하였다. The drug treatment for sexual impulse was legislated on July 23, 2010, and the law has taken effect since July 24, 2011. 'The drug treatment for sexual impulse' stipulated in this law is called as 'Chemical Castration', which was introduced for prevention of the secondary crime of sexual violence crime through the hormone treatment to suppress the sexual desire of the sexual criminals. However, the drug treatment for sexual impulse has some constitutional problems in its nature as well as debates over the likeliness of the prevention of the offenders from committing crimes again. We evaluated the effects of pharmacological interventions on target sexual behavior for people who have been convicted or are at risk of sexual offending using a variety of already published clinical studies. In conclusion, scientific evidences for the drug treatment for sexual impulse were quite too small to decide whether or not this treatment is really efficacious to prevent of recidivism. However, relatively various side effects were reported. Moreover, many guidelines requires informed consents before carrying out the treatment. Thus, current drug treatment for sexual impulse is not scientifically proven to prevent secondary crime of sexual violence criminals and we raise the concerns about maintaining current treatment law.

꽃며느리밥풀 Ethyl acetate 분획물의 예쁜 꼬마선충에 대한 항산화 효과
김준형,박창범,박종현,권강무,황인현,마상용,오석흥,김대근,Kim, Jun Hyeong,Park, Chang Bum,Park, Jong Hyun,Kwon, Kang Mu,Hwang, In Hyun,Ma, Sang Yong,Oh, Suk-Heung,Kim, Dae Keun 한국생약학회 2022 생약학회지 Vol.53 No.2
Caenorhabditis elegans model system was used to investigate the antioxidant activity of methanol extract of Melampyrum roseum (Scrophulariaceae). The ethyl acetate soluble fraction of the M. roseum methanol extract showed the best DPPH radical scavenging activity. The ethyl acetate fraction was measured for the activity of superoxide dismutase (SOD), catalase, and oxidative stress tolerance by using C. elegans along with reactive oxygen species (ROS) level. In addition, to confirm that the regulation of the stress response gene is responsible for the increased stress tolerance of C. elegans treated by the ethyl acetate fraction, SOD-3 expression was measured using a transgenic strain. As a result, the ethyl acetate fraction increased SOD and catalase activity, and decreased ROS accumulation in a dose-dependent manner. In addition, the ethyl acetate fraction-treated CF1553 worm showed higher SOD-3::GFP intensity than the control worm.
