More than 3,100 species of Phaleothripidae have been recorded around the world and they are divided into 12 tribes in 2 subfamilies. As the result of survey of the specimens preserved in various collections in Korea and additional collection by authors from 1998 to 1999, total 24 genera 35 species of phlaeothripidae were revised including 10 species new to Korean fauna. The descriptions of each species, illustrations for major morphological characters, distributions, host plants, depositaries and identification keys were give. Specimens which have been recorded as Haplothrips chinensis (Priesner) previously in Korea, were recognized as misidentification of H. brevitubus (Karny) on the basis of the shpe of male aedeagus. Elaphrothrips antennalis Bagnall and E. coreanus Woo which were reported that distribute in Korea were excluded from Korean fauna.

In order to evaluate the efficacy and safety of risperidone, 10 patients with chronic schizophrenia were examined for 8 weeks in a silgle-open study. After the wash-out period of 1 week, risperidone was administered. Efficacy was evaluated by means of Positive and Negative syndrome Scale for Schizophernia(PANSS) and Clinical Global Impression(CGI). Safety assessment included the Extrapyramidal Symptom Rating Scale(ESRS), vital signs, body weight, ECG, and laboratory tests. The results were as follows 1) On the PANSS total score, there was significant improvement of total score after 1 week (P<.05) of administratiom. 2) On the PANSS positive and negative subscal, there were significant improvement of posotive and negative scores after 2 weeks (P<.05) of administration. 3) On the PANSS general psychopatholgy subscals, there were significant improvement of general psychopathologyscores after 1 week (P<.05) of administratiom. 4) On the CGI, there was significant decreasement of clinical impression of severity of schizophrenia score after 2 week (P<.05) of administration. 5) A statistically significant increase in body weight (P<.05) was observed after 8 weeks of administration. 6) EPS reached the peak at the end of the 1st week of administration of risperidone (11.8± 24.25) but they were easily relieved by addition of benztropine and clonazepam. There was not significant change in laboratory tests, vital sign, ECG after 8 weeks of administration. These results suggest that Risperidone is an effective antipsychotics and clinically safe except for increased body weight in chronic schizophrenia.

Prediction of thrapeutic response to radioiodine in Graves' disease is poorly understood. Although thyrotropin binding inhibitor immunoglobulin(TBII) level is a strong index for relapse after antithyroid drug medication, conflicting results are reported regarding its prognostic significance in Graves' disease treated with RAI. This study is dengned to evaluate possible relationship between post-treatment hypothyroidism and TBII in Graves' disease treated with RAI. Fourty two patient with Graves' disease after radioiodine treatment were studied retrospectively. The subject were divided into hypothyroid group and euthyroid or hyperthyroid group. We evaluated the association of hypothyroidism and TBII with radioiodine treatment dose. The mean age of hypothyroid group was 48±11 years and euthyroid or hyperthyroid group was 47±12 years. There was no difference in two groups. And there was no significant difference in post- treatment TBII between two groups(49.9±28.5%, 29.9±14.3%, p-value >0.05). The treatment-dose had no influence on post-treatment thyroid state. Euthyroid or hyperthyroid group was done with 13.6±6.9mCi and hypothyroid group was 17.0±10.4mCi(p-value > 0.05). TBII had no prognostic significance on long-term hypothyrodism in Graves' disease treated with radioiodine. And, treatment-dose had no influence on post-treatment thyroid state.

배경 : 폐경후 골다공증은 심각한 문제로 대두되고 있다. 현재 Alendronate는 폐경후 골다공증의 치료제로서 널리 쓰이고 있다. 저자는 Alendronate의 골밀도에 효과를 알아보고 골다공증의 위험인자에 따른 Alendronate의 반응 정도를 평가하기 위하여 본 연구를 수행하였다. 방법 : Alendronate를 평균 12개월간 복용한 35명의 폐경후 골다공증환자에서 체질량지수와 폐경후 기간에 따른 치료효과를 조사하였다. 결과 : 전체 대상군에서 Alendronate 10㎎을 12개월간 투여한후 골밀도의 평균 변화율은 요추와 대퇴골 경부에서 각각 7.83±7.39%와 2.99±9.22%이었다. 과체중군에서 평균변화율은 요추와 대퇴골 경부에서 각각 7.15±4.5%와 3.05±2.86%였다. 양군간에 통계적 유의성이 있는 차이는 없었다. 폐경후 7년이 경과되지 않은 군에서의 평균변화율은 요추와 대퇴골 경부에서 각각 6.9±5.3%와 5.71±0.08%였다. 양군간에 통계적인 유의성이 있는 차이는 없었다. 결론 : 마른체형이 골다공증의 발병에는 영향이 있으나, Alendronate 치료효과의 차이는 없는 것을 확인할 수 있었다. 더불어 폐경이 있고 7년이 초과된 군과 년이 경과되지 않은 군에서의 Alendronate 치료효과의 차이는 없는 것을 확인할수 있었다. 이는 골흡수가 상당히 진행된 상태에서도 Alendronate가 치료효과를 가지고 있음을 반영한다고 할 수 있겠다. Postmenopausal osteoporosis is a serious health problem. The aminophosphonate Alendronate is widely used for treatment of postmenopausal osteoporosis. We studied the effect of l0㎎ of alendronate given daily for mean 12 months on bone mineral density in 35 women(mean age 61yrs. mean BMI 23.24㎏/m^(2)) with osteoporosis. An over weight group is defined such that BMI was above 23㎏/m^(2). All the women received 1500㎎ calcium carbonate daily. The bone mineral density of L-spine and femoral neck was measured by dual-energy X-ray absorptiometry. Alendronate increased BMD at mean 12 months at the L-spine (7.15±4.5%) and femoral neck(3.05±2.86%) in normal women. Alendronate increased bone mineral density at 12 months at the L-spine(6.00±5.3%) and femoral neck(4.17±4.87%) in overweight women. There was no difference between two groups. In the less than 7 years group of postmenopausal duration. alendronate increased bone mineral density at 12 months at the L-spine(6.9±4.9%) and femoral neck(3.18±7.1%). In the more than 7 years group of postmenopausal duration, alendronate increased hone mineral density at 1% months at the L-spine(6.5±5.3%) and femoral neck(5.71±0.08%). There was no difference between two groups. In postmenopausal women with osteoporosis, therapy with alendronate produced significant increases in BMD of the L-spine and femoral neck in both group. There was no difference between normal and over-weight groups. and between less than 7 years group and more than 7 years group of postmenopausal duration.

지금까지 퓨리에 변환이 신호 처리법으로 가장 널리 사용되고 있다. 그러나, 이 방법은 신호의 주파수 성분이 시간에 대하여 어떻게 변화하는지를 표현하지 못한다. 따라서, 최근 이와같이 비정상신호를 표현하지 못하는 퓨리에 변환의 단점을 보완하여, 신호의 시간과 주파수에 대한 정보를 동시에 표현할 수 있는 시간-주파수 해석법들이 개발되기 시작하였다. 본 연구에서는 인공열화된 SUS 316강의 초음파 신호를 시간-주파수 해석법으로 분석하였다. 특히, 단시간 퓨리에 변화법과 위그너 빌 분포법을 이용하여 초음파 신호의 주파수 성분과 특성을 분석하였다. Fourier transform has been one of the most commonly used tools in study of frequency characteristics of signal. However, based on the Fourier transform, it is hard to tell whether a signal's frequency contents evolve in time or not. Recently, to overcome Fourier transform fault, not to represent non-stationary signal, time-frequency analysis methods are developed and those can represent informations of signal's time and frequency at the same time. In this study, we analysed ultrasonic signal for degraded SUS 316 with time-frequency analysis method. In particular, the methods such as short time Fourier(STFT) and Wigner-Ville distribution(WVD) were used to extract frequency contents and characteristics from ultrasonic signals.
