Examined in this article are the Seo’eol figures of the Goryeo period, who were also the former version of the Joseon Seo’eol figures. They were called as a whole as ‘Seo/Eol’ in Joseon, but in Goryeo there was a strict distinction between ‘Seo(庶)’ and ‘Eol(孼).’ In the early half of the Goryeo period, the latter(“Eolja” figures) were not allowed to be appointed to governmental positions, and the former(“Seoja” figures) were in some cases restricted from applying for the dynastic competitive examination and was not allowed to rise above certain level of posts inside the government. But coming into the second half of the Goryeo period, not only cases of Seoja figures but also those of Eolja figures, in which they were able to apply for the dynastic exam and rise to the highest level of posts inside the government, started to emerge. We can see such changes inside the royal family as well, as the Eolja sons of the king, who were formerly without any right to claim succession to the throne and were forced to become Buddhist priests, were now entitled to become governmental officials or receive honorary entitlements. We can see that from the case of King Gongmin-wang’s Eolja son Wang Wu, who was enthroned in 1374 as Gongmin-wang’s successor. Elevation in the Eolja figures’ status in the second half of the Goryeo period was enabled in the wake of the Yuan imperial government’s strong and steady influences and interventions into Goryeo internal affairs. At first, the Eolja figures mounted individual attempts and efforts to use the situation to their advantage. And when they grew sufficiently accustomed to the Yuan imperial order, their acknowledgement of the Yuan order, its law codes which were not without Chinese elements, and the Chinese nature of such behavioral protocols, all enabled them to accept the notion that Eolja figures deserve new chances and especially avenues of career advancement which were not available for them before. The Yuan law code which dictated and defined the status and rights of the ‘Seo(庶)’ figures literally granted the Seo and Eol figures in Goryeo the right to claim fiscal properties and career opportunities. The Goryeo leadership, including all the Confucian intellectuals, positively responded to the situation and recognized the Eolja figures’ political and social rights. Their status elevation did not involve anything abnormal or illegal, and even after Yuan lost its influences, they maintained such elevated status, which explain how the social status of the Seo/Eol figures in the early half of the Joseon period came to be established.

내열성의 cyclomaltodextrin glucanotransferase (CGTase)를 이용하여 열에 안정한 싸이클린 텍스트린 (CD)을 생산하기 위하여 매우 높은 CGTase 활성을 보이는 고열성이며 호알카리성인 B-13 세균을 분리하여 형태적, 생리학적 특성과 16S 리보솜 RNA 서열분석 등을 통하여 Bacillus cereus B-13으로 동정하였다. Bacillus cereus B-13을 2% 가용성 전분, 1% 효모 추출물, 1% Na_(2)CO_(3) 등을 함유하는 SYC 배지 (pH 8.5)에 접종하여 50℃에서 24시간 배양하였을 때 최고의 CGTase 활성(130 U/ml)을 보였다. 또한 부분 정제된 CGTase의 작용 최적 온도와 pH는 각각 65℃, pH 8.5-9.0 이었고 80℃이하와 pH 5.0-10.0에서 안정하였다. 1% 가용성 전분을 부분 정제한 CGTase와 작용 시켰을 때 49%의 CD 수율을 보였다. To produce a thermostable cyclodextrin by using thermotolerant cyclomaltodextrin glucanotransferase(CGTase), a thermophilic and alkalophilic bacterium isolate, designated B-13 showing the highest CGTase activity was isolated from natural sources and identified as Bacillus cereus B-13 based on the morphological and physiological characteristics, and 16S rRNA sequence. The maximal CGTase activity (130 U/ml) was obtained when Bacillus cereus B-13 was cultured in SYC medium containing 2.0% soluble starch, 1.0% yeast extracts, 1% corn steep liquor and 1% Na_(2)CO_(3) (pH 8.5) at 50℃ for 24 h and about 80% of maximal activity was also showed in the culture broth of 60℃ for 18 h . Optimum reaction temperature and pH of the partial purified CGTase for soluble starch were 65℃ and pH 8.5-9.0, respectively. The partial purified CGTase were also stable below 80℃ and pH 5.0-10.0. When 1% soluble starch was digested with the partial purified CGTase, the yield of cyclodextrin was 49%.

Despite the use of aggressive local and systemic treatment including autologous stem cell transplantation in multiple myeloma, extramedullary recurrences are common and the prognosis of these patients is poor. Many novel drugs such as thalidomide, lenalidomide and bortezomib improve the response of treatment of multiple myeloma, but some reports failed to describe thalidomide has effect in extramedullary plasmacytoma. Recent data report on the successful treatment plasmacytomas with bortezomib in patients with advanced multiple myeloma. We treated 4 relapsed or refractory extramedullary plasmacytomas with bortezomib at our institution. We recognized all these extramedullary plasmacytomas decreased and showed more than partial response. This report lends support to the efficacy of bortezomib in the treatment of plasmacytoma and describes the safe use of bortezomib. Responses may, however, be of short duration. Therefore, despite our limited experience, we propose that bortezomib may be considered a therapeutic option for such patients who have risk of radiation therapy

최근 터빈 로타 디스크 키웨이에서 많은 응력부식균열이 발견되었으며, 터빈설비의 중대한 파손을 예방하기 위해 이러한 균열은 조기에 검출 및 평가되어야 한다. 본 연구에서는 초음파탐상의 RF(radio frequency) 신호를 역전파 알고리즘에 근거한 신경회로망에 적용하여 키웨이 주변의 균열에 대한 위치, 크기 및 방향성을 평가하였다. 각 반사영역에서 수신된 여러개의 피크로 나타나는 RF 신호를 각 반사영역에 대해 하나의 최대 피크를 가지도록 처리한 후, 트랜스듀서의 위치 정보와 각 반사파의 도달시간이 들어있는 주사 데이터를 작성하였다. 이 주사 데이터로부터 각 반사영역 사이의 시간차이와 트랜스듀서의 위치 정보를 신경회로망에 적용한 결과 키웨이에서 시작된 균열의 위치, 크기 및 방향성을 평가하는데 유용함을 알 수 있었다. A number of stress corrosion cracks in turbine rotor disk keyway in power plants have been found and the necessity has been raised to detect and evaluate the cracks prior to the catastrophic failure of turbine disk. By ultrasonic RF signal analysis and using a neural network based on back-propagation algorithm, we tried to evaluate the location, size and orientation of cracks around keyway. Because RF signals received from each reflector have a number of peaks, they were processed to have a single peak for each reflector. Using the processed RF signals, scan data that contain the information on the position of transducer and the arrival time of reflected waves from each reflector were obtained. The time difference between each reflector and the position of transducer extracted from the scan data were then applied to the back-propagation neural network. As a result, the neural network was found useful to evaluate the location, size and orientation of cracks initiated from keyway.

Osteopetrosis is a rare skeletal disease of unknown etiology. Osteomyelitic changes in the jaw bones are frequently seen in this disease, especially in the mandible and may follow upon tooth extractioin. A case is reported of a 31-year-old male who was seen because of intraorally exposed bony spicule and chronic dull pain. Radiographic and haematological investigations led to the diagnosis of osteopertrosis with osteomyelitis. The striking radiologic findings were pathologic mandibular fracture and generalized skeletal thickening. The present case could be grouped under the benign form, type II osteopetrosis. With the conservative and minimally invasive modes of treatment including administration of penicillin G sodium, curettage and closed reduction, we could successfully manage the osteomyelitis and pathologic fracture associated osteopetrosis.

To obtain the fundamental data on a surface speaker made to lure fish school by pure sound, three surface speakers were made of moving coil driver units of 75W and 50W respectively. Their frequency characteristic was measured in the range of 200 - 4mHz that could be used in luring fish school. The results of the measurements in air and sea are follows. 1. The input and output wave forms of a surface speaker were similar to each other in measurement frequencies in air. Then sound pressure of a surface speaker made of 75W driver units among them was over 130dB(0dB re 20μ Pa) in the range of 300 - 400Hz maximally. 2. When the surface speaker with 75W driver units emitted the measurement frequencies at sea. Sound pressure classified by the depth of water were over 140dB at 1m and 120dB at 20m(0dB re 1μ Pa) respectively.

이종일,서경원 대한방사선 방어학회 1994 방사선방어학회지 Vol.19 No.1

공기중 방사성요드 농도로부터 체내피폭선량을 간편하게 평가할 수 있는 전산프로그램 TCMI(Three-Compartment Model for Iodine)를 개발하였다. 이 프로그램은 국제방사선방어위원회 권고 54(ICRP Publ. 54)의 3격실모델 및 호흡기모델에 따라 작업시간과 작업장의 공기중 방사성요드 농도로부터 갑상선부하량, 선량당량, 예탁선량당량 및 뇨를 통한 배출율을 시간의 함수로 평가한다. TCMI 코드를 이용함으로써 급성, 만성 및 급만성 등 구체적 피폭형태에 따른 갑상선부하량과 선량당량 그리고 뇨를 통한 배출율을 평가하여 체내피폭평가의 적용성을 검토하였다. 또한 공기중 I-131 농도와 작업시간에 따른 갑상선부하량과 피폭선량을 간편하게 평가할 수 있는 식과 표를 제시하였다. The TCMI(Three-Compartment Model for Iodine) computer code has been developed, which is based on the three-compartment model and the respiratory model recommended in ICRP publication 54. This code is able to evaluate the thyroid burden, dose equivalent, committed dose equivalent and urinary excretion rate as time-dependent functions from the input data: wording time and the radioiodine concentration in air. Using the TCMI code, the time-dependent thyroid burdens, the thyroid doses and the urinary excretion rates were calculated for three specific exposure patterns ; acute, chronic and periodic. Applicability as an internal dose evaluation method has been assessed by comparing the results with some operational experiences. Simple equations and tables are provided to ve used in the evaluation of thyroid burden and the resulting doses for given I-131 concentration in air and the working time.

Stabilization of organic sludges using earthworms was conducted in a laboratory to investigate the effect of feed rate on the vermistabilization, and feasibility of vermistabilization of various sludge was also carried out to further wider application of vermistabilization. Sludges used in this study were septic tank sludge, papermill sludge and brewery sludge. Sludge reduction, cast production, earthworm growth rate and cocoon production were monitored periodically to check degree of stabilization. Feed rate of septic tank sludge did not have a notable effect on the sludge reduction and cast production per unit weight or earthworm. There was also no difference in the earthworm growth rate per unit weight of the sludge removed among the different sludge feed rate. The amount of septic tank sludge, papermill sludge and brewery sludge per gram of earthworm per day were 0.06, 0.05, and 0.02g, respectively. The weight of increase of earthworm per unit weight of the sludge removed was 0.18g/g for the septic tank sludge, 0.21g/g for the papermill sludge, and only 0.06g/g for the brewery sludge. It was therefore concluded that brewery sludge was not suitable for vermistabilization mainly due to high organic content to be easily converted organic acid. The concentrations of several heavy metals, volatile solids, total organic carbon and total kjeldahl nitrogen in the cast were generally lower than those in the raw sludges.
