Objectives: Since 1994, the number of North Korean defectors, escaping North Korea and entering South Korea, has increased rapidly.As the number of defectors has increased the role of non-governmental organizations(NGOs) in assisting the defectors' adaptation to their new society has become more important.To increase the successfulness and effectiveness of NGO activities, their experiences were surveyed and analyzed. Methods: Representatives or acting staffs of 11 NGOs presently supporting North Korean defectors' adaptation to South Korean society were interviewed by researchers between June 21 and October 14, 2000.And one focus group discussion meeting with 26 NGO personnel from 13 NGOs was held on November 4, 2000. Results: As for their stated purpose of activity; to help defectors become good citizens (7), to transform defectors into mediate personnel between North and South Korea (5), to protect the human rights of the North Korean people (3), and th advocate their religions (3).Out of the 11 organizations, only 5 had their own educational program for volunteers.The contents of the NGO's support for volunteers were as follows; counseling (7), introduction of employment and job education (6), direct financial support (5), creation of one-to-one relationships (4), assistance for their religious life (2), assistance with English study and mathematics (1), and medical service (1).NGOs listed the following difficulties; financial (7), human relationship with defectors (6), lack of volunteers and management of them (4), problems in the relationship with the South Korean government (3).NGOs stated a need for close cooperation with other NGOs, involving the activation of NGOs Association (5), and co-operative joint actions (4).Conclusion: Firstly, NGOs need to specialize in their field of activity.Their lack of specialized areas and of ability is the man obstacles to NGOs intercooperation and a major impediment on their effective operation.Secondly, NGOs should be careful in their direct financial support to defectors, because such a form of support has many serious governmental cooperation.The government also needs to have a more open mind in its dealings with NGOs.Fourthly, NGOs should cooperate, especially in areas of joint concern such as volunteer education program.Fifthly, NGOs should pay attention to their volunteers' personnel management and development.Sixthly, NGOs need to increase the degree of activeness with which defectors seek support from NGOs.Usually, it is the NGOs, which play an active role in the support process, so that defectors become passive and dependent leading to many problems.

Objectives : In 2002, the Korean Medication Algorithm Project for Major depressive Disorder (KMAP-MD) was published, but there has been a need for a guideline about detailed issues of depressive disorder. We revised KMAP-MDD andreestablished Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) in 2006. Methods : A questionnaire had been developed by the executive committee for KMAP-DD. The review committee consisted of 101 experienced psychiatrists. From the total of 22 questions in the questionnaire, 7 questions were evaluated for these subjects . We classified the expert opinions to 3 categories according to its confidence interval; first, second and third line. Results : SSRI and venlafaxine were the first line antidepressants (AD) for atypical and melancholic depression. For dysthymic disorder and minor depressive disorder, SSRI was recommended as the first line medications. Only AD medications was a preferred initial strategy for treating premenstrual dysphoric disorder, mild to moderate and severe non-psychotic postpartum depression. In severe psychotic postpartum depression, combination therapy of AD and atypical antipsychotics was the treatment of choice. SSRI was preferred when considering sedation, anticholinergic and cardiovascular adverse effects. Also, experts recommended mirtazapine against gastrointestinal adverse effects and bupropion in avoiding sexual dysfunction. Conclusion : These results suggest that clinicians have to consider both clinical situations and drug adverse effects in the choice of antidepressant medications.

Purpose : otal prostate volume has been known to be poorly correlated with other parameters used to assess benign prostatic hyperplasia(BPH), including international prostatic symptom score(IPSS), peak flow rate(Qmax). This study was aimed to investigate the possible correlation between transition zone index(TZI), IPSS and Qmax in patients with clinical benign prostatic hyperplasia(BPH). Materials and methods : From September 1999 to December 2000, A total of 95patients with clinical BPH were evaluated total prostate volume(TV), transition zone volume(TZV), TZI, IPSS and Qmax. TZI was determined as the ratio between transition zone volume(TZV) and total prostate volume(TV). Results : The relationships between IPSS and TV, TZV, and TZI were not statistically significant. A statistically significant relationship was observed between TZV, TZI and Qmax and between TV, TZV, TZI and age. Conclusion : These results suggest that TZV, TZI may not be a useful method to assess symptom severity in BPH patients but may be limited clinical parameters.
