본 연구는 자기관리중재전략을 포함한 자기점검표 사용이 지적장애학생의 작업 생산성에 미치는 영향을 분석하고자 실시되었다. 이를 위해 전공과에 재학 중인 지적장애 학생 1명을 대상으로 구조화된 교실 환경에서 실험을 진행하였다. 실험은 행동 간 중다기초선설계를 사용하여 진행하였다. 독립변인은 자기점검 카드를 작성하는 자기점검, 자기평가, 자기강화를 포함한 자기관리 중재이며 자기점검 카드로 구체화하였다. 종속변인은 조립작업, 분류작업, 포장작업행동의 작업 생산성이었으며 1회기 동안 생산한 생산품 개수와 정품의 비율로 측정하였다. 중재의 투입은 조립작업행동, 분류작업행동, 포장작업행동의 순서로 투입되었으며, 이전 행동에서의 효과가 나타나고 반응이 안정되면 다음 행동에서 중재를 투입하였다. 중재기간 동안 모든 작업 행동에서 1회기 동안 총 생산품 개수가 증가하였고 정품의 비율도 향상되었다. 중재가 종료된 후에도 향상된 작업 생산성은 유지되거나 더 향상되었다. 이러한 연구 결과는 자기점검표 사용이 학생의 작업 생산성에 긍정적인 영향을 미쳤음을 보여준다. The purpose of this study was to analyze the effects of using self-monitoring checklist containing self-management intervention on work productivity. For this purpose a student with intellectual disability who placed in special schools’ majoring courses was selected as a participant, and the experiment was conducted in a structured classroom setting. For this study, a multiple probe design across settings was used to identify a potential functional relationship between independent and dependent variables. The independent variable of this study was the self-management intervention which was materialized as ‘Self-Monitoring card’ including self-monitoring, self-evaluation, and self-reinforcement. The dependent variable of this study was the student’s work productivity which was measured by the number of products and the ratio of products without error at one period. During the intervention student’s work productivity was improved in all working settings, and the improved work productivity was maintained or more improved after the intervention. The result from this study demonstrated that the self-monitoring checklist has a positive effects on student’s work productivity.

Perillae Herba has been traditionally used for the sedation in the oriental countries. Therefore, this study was conducted to determine whether Perillae Herba ethanol extract (PHEE) enhances pentobarbital-induced sleeping behaviors in animals. In addition, the possible mechanisms are demonstrated. PHEE (12.5, 25 and 50 mg/kg. p.o.) reduced the locomotor activity in mice. PHEE reduced sleep latency and augmented the total sleep time in pentobarbital (42 mg/kg, i.p.)-induced sleep in mice. Furthermore, the number of sleeping mice treated with sub-hypnotic pentobarbital (28 mg/kg, i.p.) increased. PHEE (50 mg/kg. p.o.) decreased the sleep/wake cycles and wakefulness, and increased total sleeping time and NREM sleep in electroencephalogram (EEG) of rats. In addition, PHEE (0.1, 1.0 and 10 mg/ml) increased the intracellular Cl- level through the GABA receptors in the hypothalamus of rats. Moreover, the protein of glutamate decarboxylase (GAD) was overexpressed by PFEE. It was found that PHEE enhanced pentobarbital-induced sleeping behaviors through GABAA-ergic transmissions.

Sinomenium acutum has been long used in the preparations of traditional medicine in Japan, China and Korea for the treatment of various disorders including rheumatism, fever, pulmonary diseases and mood disorders. Recently, it was reported that Sinomenium acutum, has sedative and anxiolytic effects mediated by GABA-ergic systems. These experiments were performed to investigate whether sinomenine (SIN), an alkaloid derived from Sinomenium acutum enhances pentobarbital-induced sleep via γ-aminobutyric acid (GABA)-ergic systems, and modulates sleep architecture in mice. Oral administration of SIN (40 mg/kg) markedly reduced spontaneous locomotor activity, similar to diazepam (a benzodiazepine agonist) in mice. SIN shortened sleep latency, and increased total sleep time in a dose-dependent manner when co-administrated with pentobarbital (42 mg/kg, i.p.). SIN also increased the number of sleeping mice and total sleep time by concomitant administration with the sub-hypnotic dosage of pentobarbital (28 mg/kg, i.p.). SIN reduced the number of sleep-wake cycles, and increased total sleep time and non-rapid eye movement (NREM) sleep. In addition, SIN also increased chloride influx in the primary cultured hypothalamic neuronal cells. Furthermore, protein overexpression of glutamic acid decarboxylase (GAD65/67) and GABAA receptor subunits by western blot were found, being activated by SIN. In conclusion, SIN augments pentobarbital-induced sleeping behaviors through GABAA-ergic systems, and increased NREM sleep. It could be a candidate for the treatment of insomnia.
