정지궤도 위성과 지구국간 광통신을 대기상태와 앙각의 함수로써 해석할 수 있는 한모델(Han's model)을 제시하였다. 한모델에서는 대기상태를 맑은날, 구름낀 날, 안개, 헤이즈, 비, 눈의 여섯가지 전형적인 상태로 구분한다. 비트오류을 $10^{-7}$을 만족하는 데이터 전송속도를 한모델을 이용하여 상향링크와 하향링크에 대해 해석하였다. 상향링크시의 포인팅손실이 하향링크시의 대기에 의한 공간 가간섭 저하보다 크기 때문에 데이터 전송속도는 하향링크 보다 오히려 상향링크시에 제한됨을 알 수 있었다. Han's model, which is able to analyze optical communication between earth station and geo-satellite as a function of atmospheric conditions and elevation angles. is presented. In Han's model, atmospheric conditions are roughly classified into six basic types; clear sky, cloud, haze, fog, rain and snow. Data rate satisfying for the BER below $10^{-7}$ is analyzed by Han's model in case of up-link and down-link, respectively. Data rate is more limited by up-link than by down-link because the pointing loss caused by atmosphere on the up-link is greater than the spatial coherence degradation caused by atmosphere on the down-link.

Background p19arf, primarily known as a tumor suppressor, has also been reported to play an essential role in normal development of mouse eyes. Consistently, lack of p19arf has been associated with ocular defects, but the mixed background of the knockout (KO) mouse strain used raised a concern on the accuracy of the phenotypes observed in association with the targeted gene due to genetic heterogeneity. Object We carried out a study to investigate into the efect of genetic background on the manifestation of p19arf KO associated phenotypes. Methods We characterized the phenotypes of novel p19arf KO mouse lines generated in FVB/N and C57BL/6J using a transcription activator-like efector nuclease (TALEN) system in comparison to the reported phenotypes of three other p19arf-defcient mouse lines generated using homologous recombination. Results Ninety-fve percent of FVB/N-p19arf KO mice showed ocular opacity from week 4 after birth which worsened rapidly until week 6, while such abnormality was absent in C57BL/6J-p19arf KO mice up to the age of 26 weeks. Histopathological analysis revealed retrolental masses and dysplasia in the retinal layer in FVB/N-p19arf KO mice from week 4. Besides these, both strains developed normally from birth to week 26 without increased tumorigenesis except for a subcutaneous tumor found in a C57BL/6J-p19arf KO mouse. Conclusion Our fndings demonstrated surprisingly variable manifestation of p19arf-linked phenotypes between FVB/N and C57BL/6J mice, and furthermore between our mouse lines and the established lines, indicating a critical impact of genetic background on functional study of genes using gene targeting strategies in mice.

We experienced a 25 year-old male patient with typhoid fever complicated with massive hemoptysis. Pulmonary complication in typhoid fever is very rare and to our knowledge, there has been no report of hemoptysis as a main cause of death with this disease. We herein report a rare case of typhoid fever.

小豆 成分育種올 위해 主要化學成分의 遺傳關係를 早期에 推定하고 앞으로의 育種計劃에 대한 基礎資料를 얻고자, F_l, F_2 兩世代의 優性程度 및 遺傳子 分布狀態, 그리고 遺傳力과 相關係數等을 推定한 바, 그 結果는 다음과 같다. 1. 優性程度는 全成分에서 各各 超優性으로 遺傳되었으나 Mg는 不完全優性(F_l世代)과 超優性(F_2世代)으로 世代間에 差異가 있었고, F_l 世代의 粗脂肪, 灰分및 Mg와, F_2 世代의 灰分에서는 非對立遺傳子의 關與가 多少 있었다. 2. 各 成分의 遺傳力은 兩世代間에 비교적 낮았으나 K와 粗脂肪은 他成分보다 높았다. 3. 形質相互間의 相關關係에서 灰水化物은 他成分間과 負의 相關을 보였고, 기타 成分들은 相互 正의 相關이었는데, 蛋白質과 粗脂肪은 F_2世代에서 有意한 正의 相關을 나타내었다. A set of 36 crosses of F/s and F_2's from 9 X9 diallel crosses of nine azdukibean varieties were analyzed for estimating genetic parameters, such as gene action, degree of dominance and genotypic correlation. Seven chemical com positions, i. e., carbohydrate, protein, crude fat, ash, K, Ca and Mg were observed. The results obtained are summarized as follows: 1. In Vr-Wr graphical analyses, all chemical compositions except Mg in F/s were found to be inherited in over dominance. 2. The highest heritability value was found in K in both F/s and F/s, but the value of ash was the lowest. 3. The genotypic correlations between carbohydrate and other chemical compositions were negatively correlated, but that between protein and crude fat was positively correlated in F_2's.

The 948 goat sera were serologically tested for ten pathogens including bovine viral diarrhea (BVD), bovine herpes virus type-1 (BHV-1) and parainfluenza virus type-3 (PI-3). By viral neutralizaion test, three pathogens including BVD virus, BHV-1, PI-3 were applied for screening each neutralizing antibody and its titration. Among 948 sera, there were 215 seropositives (22.7%) against BVD virus, 25 (2.6%) against BHV-1 virus, and 161 (17.0%) against PI-3 virus, respectively. In the seropositive cases to BVD virus, provincial prevalence of them were recorded as Gyeongnam(30.8%) for the highest one, while as Jeonbuk (15.8%) and Gyeongbuk(l6.7%) relatively for the lower ones. Among them, higher than 1:8 in antibody titration was classified as 74 cases (34.4%) which were suspected the cycle of its infection in their herds. Among the seropositives to BHV-1, it was relatively lower prevalence rate ranging from 1.7% to 6.7% that those of BVD virus and PI-3, but more importantly they were prevailing across the country. Most of the seropositive cases (42.9%) to PI-3 were classified as 1:4-1:16 in titration, but also distributed all around the country. The prevalence in goats varied according to areas (15.8 to 30.8%). Related to the provincial prevalence of three viral agents in Korean goats, it seemed that three viral pathogens would be directly or indirectly involving in various disorders as primary or secondary causative agents resulting in decreased productivity.

The two sets of diallel crosses (5×5 and 9×9 crosses) from nine adzukibean varieties (Yeongdong Jeogdu, Gongju Baegdu, Gyeonggi Gaeguri, Wase Dairuyu No. 1, Natsu Adzuki, Maruba No. 1, Jeogdu, Nesumi Mochi and Hongcheon Jeogdu) were grown in the field for estimating genetic parameters, such as gene action and combining ability in two different generations, F_1 and F_2. From a series of experiments conducted in 1976 to 1977, 1981 to 1982, and two agronomic characters, i.e., days to flowering and 100-grain weight were observed. The results obtained are summarized as follows: 1, In finks and Hayman's (Vr-Wr) graphic analyses, days to flowering and 100-grain weight of F_1's and F_2's from 5×5 and 9×9 crosses were found to be inherited in partial dominance. 2. Mean squares of GCA and SCA were significantly different among two characters in all generations of different crosses, and those of GCA were higher than SCA. 3. The highest GCA effects for days to flowering were expressed Jeogdu in 5×5 cross, Hongcheon Jeogdu in 9×9 cross, ana Jeogdu for 100-grain weight showed relatively high effects in two generations of 5×5 and 9×9 crosses. 4. SCA effects were different among Parents and characters in the different crosses, but the higher SCA effects were exhibited in the hybrid between Yeongdong Jeogdu and Nesumi Mochi in two generations of 5×5 cross.

Thirteen-year-old girl complaining of the swelling and pain on the left midface visited our dental hospital. On the radiogaphic examination, well-defined radiolucent lesion with hyperostotic border was found in the left maxilla accompanying with the external root resorption of the involved teeth and the displaced second molar. CT showed calcified bodies, thinning of hard palate, inferior orbital wall and lateral wall of nasal fossa, and thinning and perforation of the buccal plate of the maxilla. Enucleation and curettage of the lesion and nasoantrostomy was carried out and histopathologic examination mainly showed a solid tumor tissue composed of odontogenic epithelium and pulp tissues admixed with dentin and enamel formation. And some part of reduced follicular epithelium of tooth germ showed a change mimicking calcifying odontogenic cyst, Taken together, we concluded the lesion is an ameloblastic fibro-odontoma with a change of calcifying odontogenic cyst.
