This paper proposes a shift-register-based multichannel ultrasonic focusing delay control method using a complex programmable logic device (CPLD) for a high resolution of ultrasonic focusing system. The proposed method can achieve the ultrasonic focusing through the delay control of driving signals of each ultrasonic transducer of an ultrasonic array. The delay of the driving signals of all ultrasonic channels can be controlled by setting the shift register in the CPLD. The experiment verified that the frequency of the clock used for the delay control increased, the error of the focusing point decreased, and the diameter of the focusing point decreased as the length of the shift register in the proposed method. The proposed method used only one CPLD for ultrasonic focusing and did not require to use complex hardware circuits. Therefore, the resources required for the design of an ultrasonic focusing system could be reduced. The proposed method can be applied to the fields of human computer interaction (HCI), virtual reality (VR) and augmented reality (AR).

Objectives : Schizophrenia is equally distributed in both sexes. However, later-onset, milder psychopathology, and better outcome are associated with the females. This reason is thought to be partly due to the estrogen system. Recently, it was suggested that estrogen receptor 1(ESR1) gene polymorphisms might affect the expression of ESR1 and were associated with several psychiatric disorders. Thus, we investigated the association between two single nucleotide polymorphisms(SNPs) in the ESR1 gene and Korean schizophrenic patients in this study. Methods : Genotype, allele, and haplotype frequencies of the two SNPs(rs 2234693 and rs 2228480) were analyzed between 218 Korean controls and 158 Korean schizophrenic patients. Also, age of onset and negative symptom scale scores according to genotypes were analyzed in the patients with schizophrenia. Results : There was a significant difference in allele frequencies of rs 2234693 between the schizophrenic patients and the controls(p=0.03). Genotype distributions(p=0.03) and allele frequencies(p=0.01) of rs 2234693 were significantly different between the female schizophrenic patients and the female controls. The frequency of TC-CC genotypes compared with TT genotype in the female schizophrenic patients was significantly higher than that in the female controls(OR=2.36). The mean age of onset in the schizophrenic patients with TC-CC genotypes was significantly lower than that in the patients with TT genotype. The frequency of rs 2234693C- rs 2228480G haplotype in the female schizophrenic patients was relatively higher than that in the female controls. Conclusions : These results of our study support the possibility that the ESR1 gene polymorphisms might be involved in the susceptibility of females to schizophrenia and play a role in sex difference of schizophrenia.

목 적: 현재 한국의 정신과 사 년 차를 대상으로 정신과 전공의 수련 과정에서 이루어지는 약물 치료 이외의 치료 방법들에 대한 현황을 파악하고 분석해 봄으로써 앞으로의 다양한 치료 방법들에 대한 정신과 전공의 수련 교육의 내용과 수준, 교육 방식을 설정하고 문제점 및 개선 방안을 모색해 볼 수 있는 계기를 마련코자 한다. 연구대상 및 방법: 두 달 동안 전국 72개 수련병원에서 근무 중인 전공의 사년 차 126명을 대상으로 설문 검사를 실시하였고 총 63명(50%)이 응답하였다. 설문지의 보기에는 총 39가지의 치료법을 제시하였다. 결 과: 현 전공의 사 년 차가 수련 기간 동안 경험한 치료 술기의 수는 최소 1개에서 최대 17개로, 평균 6.9개의 치료술기를 경험하 였다. 지역별 차이(수도권 지역과 비수도권 지역)와 전공의의 치료 술기의 다양성은 유의한 차이를 보이지 않았다. 병원 내 전문의의 수와 연 차별 전공의의 수는 치료 다양성은 양의 상관관계를 맺고 있었다. 전공의 들은 현재 병원 내에서 시행하고 있지는 않으나 관심이 있는 분야로 최면(45%), EMDR(26.7%), 예술치료(21.7%)를 꼽았다. 결 론: 전공의가 경험하는 치료 내용의 양적 및 질적 차이가 줄어들 수 있도록 본 학회는 물론 각 분과 학회의 배려가 필요할 것이다. Objective:The aim of this study was to survey fourth year psychiatric residents' experience about the application of non-pharmacological therapies during their residency training in Korea. This survey may help trainer to determine how psychiatric trainee think about their level of education, content of education, methods of education, and current problems in psychiatric residency training, as well as to reform the non-pharmacological psychiatric therapies. Methods:A total of 63 subjects completed the questionnaires we sent. 39 types of therapy were included in the questionnaire. Results:The results of our survey showed that the total number of therapies that residents were exposed to during their four years of training ranged from 1 to 17 (6.9±3.3). The regional disparity, the nation’s metropolitan area vs non-metropolitan area, had non-significant effect on the diversity of non-pharmacological psychiatric interventions. The number of faculty members and the number of residents were positively correlated with the diversity of nonpharmacological psychiatric therapies. The results of our survey also showed that many residents were interested in other types of non-pharmacological psychiatric interventions that they have not been exposed to, such as hypnosis (45%), EMDR (26.7%), and art therapy (21.7%). Conclusion:It would be necessary to reduce differences of both quantity and quality of therapies experienced among psychiatric residents for improving in residency training system.
민간건강보험에서 정신과 질환에 대한 보험비 지급 관련 약관 현황과 문제

Objectives : Recently, Korean psychiatrists have noticed the complaints from probands and family members that private health insurance companies do not pay for most psychiatric disorders. Furthermore, Probands cannot even apply for insurance because of their medical record of psychiatric disorders. Authors investigated and reviewed contracts of Korean private insurance companies to find reasons for banning psychiatric disorders from insurance policies. Methods : Authors reviewed more than 800 contracts from 48 insurance companies. Results : Among all the psychiatric diagnoses, few of them-dementia and some other organic mental disorders-are guaranteed to be paid from insurance companies. Less then 10 contracts say they pay for psychiatric illnesses. Most insurance companies have contracts prohibiting F codes ; however, there are not enough reasons in these contracts. Conclusions : In the private health insurance system, Psychiatric illnesses have almost no rooms. It is very urgent to add space for patients with psychiatric illnesses and psychiatrists in the insurance policies.
