An ideal program should be comprehensive. It should provide a range of levels and intensities of treatment targeted to severity of illness as well as a range of specific services targeted to individual patients' needs. Assessment should be standardized(e.g., by the Addiction Severity Index) and should be ongoing so that patients are moved from one level of treatment to another based on an assessment of their current condition. Level of treatment should be determined according to generally accepted criteria(e.g., ASAM Patient Placement Criteria). Specific services, e.g., psychiatric services and marital counseling, should be provided in accordance with the specific problems generated in the assessment Treatment modalities should be selected on the basis of proven effectiveness. Consideration should always be given to combining pharmacological with psychological treatments. Treatment show to be ineffective in repeated trials should be discarded. When possible, staff should be retrained to use a more effective modality. Staff and patient need clarity regarding treatment goals as well as the criteria to be met for particular levels and intensities of treatment; program length in general will not be fixed, even though a given number of sessions may be required to complete the basics, e.g., relapse prevention or coping skills training. Attention should be paid to the general ambience of the program, the ease of transition from one level to another, and its user friendliness. Empathy should be encouraged and confrontational approaches discouraged. However, program regulations and expectations should be clear, consistent and reinforced. Finally, the program should have ongoing methods for evaluating itself on a number of dimensions, including patient retention and outcomes.
분산감소광섬유에서의 고차 솔리통 펄스 생성 및 압축을 통한 광시간분할다중시스템 광원의 제작에 대한 연구
이덕기,김나영,박남규 한국광학회 2000 한국광학회지 Vol.11 No.2
We propose a new scheme for generating a pedestal-free, femtosecond soliton pulse train by utilizing quasI-adiabatic high order soliton pulse evolution in dispersion decreasing fiber in conjunction with the intermediate pedestal suppression stage. Compression factor over 280 was achieved from lOGHz sinusoidal input, to 176 is soliton pulse train. train. 본 논문에서는 분산감소광섬유를 이용하여 정현파를 고차 솔리톤으로 진행시켜서 원하는 펄스 압축율을 얻은 후, 수반되는 pedestal을 반응시간이 빠른 포화 흡수제(Fast Saturable Absorber : FSA)로 제거하는 현실적인 방법을 제시하였다. 또한 DDF-MALM-DDF 구조를 제안하여 280 이상의 압축율과 변환 제한에 가까운 솔리톤 펄스열을 생성할 수 있도록 하였다. 그 결과로서 광시간분할다중시스템과 광샘플링 등에 이용될 수 있는, 10GHz의 반복율과 176 fs의 펄스폭을 가지는 고품질의 솔리톤 펄스열을 구현할 수 있는 시스템을 디자인하였다.
