This study was made to investigate the degree of rice blast disease developing in various plants and also the relationship between the disease developing and the amount of content of nutrients in rice plants which were differently dressed. Possibility for culture of rice-blast race was studied and the structure of infected leaves were observed by electron microscope. 1) The varieties sampled, Pung-kwang, Jin-heung, Pal-tal, Pung-ok and Tong-il, were seeded and cultivated in pots. When fifth or sixth leaf emerged, the races of blast T,C,N were innoculated in all varieties. In dressing test Pung-ok, which leas susceptible to blast, was dressed with nitrogen fertilizer in ordinary and twofold and in none-dressing or dressing of silicon fertilizer. When the fifth or sixth leaf was appeared, races T, C, N was innoculated in each varieties of pot. In all experiment the degree of infection was checked out according to the order of leaf, and at the same time, the relationship between the degree of disease developing and the contents of nutrients by determining the total nitrogen, total sugar, phosphoric acid, kalium, silicon dioxide soluble nitrogen and soluble sugar was studied. The occurance of symptom was relatively frequent in upper primary or secondary leaf in all varieties regardless of the kind of fertilizers or their dressing amount. Comparing the occurrencies of disease development in examined varieties, Jin heung was lowest and Pung-ok was highest, while Tong-il was completely free from the infection of the disease. The race T-type attacked most seriously the varieties of Jin-heung, Pal-Tal and Pung-kwang except Pung-ok, C-type was moderate and N-type was very weak in Pung-ok. In the amount of dressing, the occurance of disease was very rare in the rice plant of N-ordinary-silicon fertilizer dressed and frequent in that of nitrogen fertilizer-twofold-and-silicon fertilizer none dressed. The disease developing differed with the races, indicating T-type was most poweful, C-type moderate while N-type was weak. In the interaction between the contents of nutrients in riceplant and the degree of disease developing, Pung-ok, which was very abundant in nitrogen, phosporic acid, glutamic acid, asp artic acid glutamine, asparagine, cystine, serine and sucrose but little in sugar, kalium and silicondioxide, was most susceptible to the disease. Jin-heung, resistant one, was opposite to Pung-ok in all aspects. As a result there was a correlation between the kind or amount of nutrients in rice plant and the disease attack. According to the amount of dressed fertilizer, the rice plant dressed in N-twofold and silicon dioxide none dressed had the larger amounts of total nitrogen, phosphoric acid, aspartic acid, glutamic acid and gldtamine but little in sugar and silicon dioxide contents. While in the rice plant dressed with N-ordinary and silicon fertilizer. the tendancy of disease occuring was low respectively. 2) The study on the cultivation of race T,C,N in the media added such organic acid as succinic acid, valeric acid, malic acid, ketoglutaric acid and such phenolic chlorogenic acid and salicylic acid was made. The result of which was as follow: ① There were no differences in growth of T,C,N type races. ② In the media added organic acid the growth was favorable. ③ In the media added chlorogenic acid the growth was promoted but in the one added salicylic acid the growth was inhibited. 3) The morphological changes of the infected waves alls the structure of hypha of blast which had penetrated into the leaf cell of Pung-ok, which was susceptible one to the disease, was observed by electric microscope. The following facts were found. ① In healthy leaves normal nucleus, mitohcondria, chloroplast, entoplasmic reticulum, vacuole and cytoplasm, especially round substances, were chearly observed by electron microspcope. ② In the infected leaves, the space of the nucleus double memberance was enlarged, and some of the nucleu walls were destroyed. The thinlayer structure of glanalamelae in lamela system was enlarged, somewhere spates were appeared while stromas were disappeared. In mitochondria the spaces of the double membrance were enlarged. ③ Cytoplasm of cell which were attacked by hypha was completely destroyed and the hypha lost their normal structure. ④ In the structure of hypha which penetrated into the cell wall of epidermis, nucleus, mitochondria, round ectoplasmic reticulum, vacuole and substances were clearly observed.

1. "녹색한우"사업단은 광역 한우 브랜드로서 규모가 크고 품질 고급화를 위하여 사양관리를 통일하고 품질의 균일성 확보를 위하여 중장기 육종전략을 수립하여 한우 브랜드를 육성시키고 있다. 2. 한우 개량을 위한 기본적인 개체정보 수집을 위하여 개체관리 자동화시스템을 구축하여 참여 대상축에 대한 DB를 구축함과 동시에 개체별, 출생정보, 혈통정보, 번식정보, 발육능력정보 등 다양한 정보를 정확하게 수립·관리할 수 있는 기반을 구축하였으며, 이를 근거로 한우 축군의 유전능력평가를 실시하여 우량 암소축군을 구축하고 관리할 수 있는 기반을 마련하였다. 그러나 상당수의 한우 브랜드는 이러한 체계적 관리시스템을 구축하지 못한 실정이며 특정 보증씨수소에 의한 개량의존도가 심화되고 있어 빠른 문제해결을 위한 방안을 마련해야 할 것이다. 3. 유전적으로 능력이 우수한 암소의 경우도 한우산업의 특성상 2산 이상의 경우 경제적 가치의 저하로 인하여 조기에 도축하는 경우가 빈번하게 일어나고 있으며, 이는 정부차원에서 우량 암소의 다산장려 정책을 추진하고 있음에도 농가의 현장적용의 효과가 부족한 것은 유전능력 평가에 의한 검증된 우량 암소 축군의 구축보다는 표현형적 자료에 근거한 표현형 선발이 진행되어 다음 세대의 송아지 능력 예측이 어려운 점 등 육종전략과 계획교배 부재 등으로 인하여 한우 브랜드의 축군 관리지침이 없다는 현실을 반영한 것이라 할 수 있다. 4. 따라서 한우 브랜드의 성공적 육성을 위하여 한우 브랜드에 참여하는 암소 축군에 대한 유전적 평가를 실시하여 우량 암소 축군을 조성한과 동시에 한우 브랜드의 차별화를 위한 자구적 육종전략 수립이 필요하다. The objectives of this study were to establish an automatic individual management system using electronic ear tag with RFID chip in Hanwoo and to evaluate an inbreeding coefficients of herd to counsel the breeding scheme and its development strategies for "Green Hanwoo" brand. The individual management system for the "Green Hanwoo" brand consisted of the 3 factors such as an ear tag with RFID chip, a mobile device for recognizing an ear tag, and a body weight measurement scale with indicator including wireless functions to send the individual information to the mobile device. This system was especially applied to 16 breeding farms only and its herds in "Green Hanwoo" brand and collected automatically the informative individual information such as birth date, sex, pedigree, and growth performance and reproductive records in "Green Hanwoo" herds. All data collected from individuals of Hanwoo herds were analyzed to calculate an inbreeding coefficients based on a pedigree information. Some of individuals in each farm had somewhat higher inbreeding coefficients due to an inappropriate mating scheme which was resulted in a decrement of genetic gain or improvement in entire herds of "Green Hanwoo" brand. Therefore, we should consider the genetic diversity of Korean proven sire and the breeding scheme with the long term development strategies for a distinguished local Hanwoo Brand, "Green Hanwoo".

The purpose of this study was to explore the relationship between the sex-role stereotype of the father and the child. We investigated the following: ⑴ Is there a relationship between the sex-role stereotype of the father and the child? ⑵ Is the age of the child a variable in the relationship between the sex-role stereotype of the father and the child? ⑶ Is the sex of the child a variable in the relationship between the sex-role stereotype of the father and the child? The subjects were 193 13-year-old students attending a middle school in Seoul and their fathers and 70 5-year-olds attending a kindergarten in Kwachon and their fathers. The test for the 193 middle school students and their fathers was the Likert Scale of the Bem Sex-Role Inventory which was utilized by the experimenters after a pretest. The instrument for the 5-year-olds was the 22 story-picture card Williams and Bunnett test(1975) modified by Lee, Sook(1982). The kindergarten fathers were tested with the same instrument as the middle school fathers. The data from these 2 tests were then compared using χ^2 test and percent(%). The result of this study were: ⑴ A relationship between the sex-role stereotype of the father and the child was found only between the sex-role stereotype of the middle school students and their fathers. ⑵ Age of the child was found to be a variable in the relationship between the sex-role stereotype of the father and the child. That is, a significant relationship was found between the sex-role stereotype of the middle school students and their fathers, but not between the sex-role stereotype of the preschool children and their fathers. ⑶ Sex of the child was found to be a variable in the relationship between the sex-role stereotype of the father and the child. That is, a significant relationship was found between the sex-role stereotype of the middle school boys and their fathers, but not between the sex-role stereotype of the middle school girls and their fathers.

In this paper, I am going to utilize the existing OAM cell, without generating an additional traffic. Firstly, I analyzed the basic structure of the existing Fiber Loop Carrier-C(FLC-C). Secondly, by making use of the loopback function, I suggested the OAM function for monitoring the network resources and transmitting the traffic information in the Fiber Loop Carrier-C. Finally, by using this kind of monitoring mechanism that is a simulation model, I measured the cell loss rate and the cell transfer delay with the information of the network traffic.

Unusual localization of digit mucous cyst: fingertip

( Sin Wook Chun ),( Hyun Ok Son ),( Suk Young Lee ),( Jong Baik Kim ),( Han Gyu Choi ),( Han Kyoung Cho ),( Byung In Ro ) 대한피부과학회 2015 대한피부과학회 학술발표대회집 Vol.67 No.1

Digit Mucous Cyst(DMC) is a common condition that is clinically characterized by a round to oval, translucent, smooth nodule. Etiologically, the cyst might rise de novo by fibroblast overproduction of hyaluronic acid. The buildup of mucopolysaccharides pushes the collagen of the dermis upward, forming a pseudocyst. Such pathogenesis is independent from adjacent joint and is considered as a focal cutaneous mucinosis. In addition, a direct connection from an osteoarthritic joint might allow joint fluid to escape and form a mucous cyst. DMC typically involves the lateral or dorsal surfaces of the distal interphalangeal joint or over the proximal nail fold. It is occasionally painful and uncomfortable. Histologically, they are more accurately classified as pseudocysts because there is no epithelial lining of the spaces. Within the stroma, multiple small, cleft-like spaces with a tendency for liquefaction and cavity formation coalesce to form large cystic spaces containing mucin. A 57-year-old male, construction worker patient had a hyperkeratotic corn-like nodule over the tip of his right middle finger for 1 year. Tenderness of the nodule made the patient uncomfortable which eventually made the nodule removed. Shaving biopsy and curettage was performed and mucinous material was drained. Histological examination had revealed characteristic features of a mucinous cyst. Interestingly, the cyst was on the fingertip, a very unusual localization.

SAPHO (synovitis, acne, pustulosis, hyperostosis, osteitis) syndrome is a systemic inflammatory disorder characterized by involving the skin, bone and joints. This osteoarticular and dermatological inflammatory disease was first reported 1987. Inflammatory osteitis can occur in sternoclavicular and sacroiliac joints with pain and tenderness; these symptoms can be a clue for diagnosis. In dermatologic field, acne on face and pustulosis on palm or sole can be seen. Patient was a 53-year-old woman with neck, chest and back tenderness who was consulted from rheumatologic department for evaluation of pustulosis on the palm and sole. Patient had acne scar on the face. Radiologic evaluation revealed that sternoclavicular osteitis without any infectious sign. Skin biopsy had been obtained from the palm and revealed that intraepidermal cavity filled with polymorphonuclear leukocytes associated with spongiform changes within the surrounding epidermis. The diagnosis of SAPHO syndrome was considered because of these clinical findings. We report a case of SAPHO syndrome, because it is rare and can be helpful for dermatologic doctors to diagnosis this disease.

울산지역 췌담관질환 환자의 간흡충 감염 실태 : 담즙검사를 기준으로 based on bile examination

이기영,주광로,김현수,신수진,이효섭,윤태권,추연익,박종호,신정우,방성조,김도하,박능화 대한내과학회 2004 대한내과학회지 Vol.66 No.5

목적 : 간흡충증의 진단은 분변 또는 담즙에서 간흡충의 성충 또는 충란을 발견하는 것이다. 담즙을 통한 간흡충 진단은 간흡충이 존재하는 담관에서 검체를 직접 채취한다는 장점과 이 검체가 분변이나 체액에 의해 희석되지 않으며, 특히 담관 폐색이 있을 경우 담즙배설 장애로 인한 분변검사의 위음성을 줄일 수 있는 가장 정확한 간흡충의 기생충학적 검사로 생각된다. 이에 저자들은 울산지역 췌담관 질환 환자에서 담즙검사를 기준으로 한 간흡충의 감염 실태를 알아보고자 하였다. 방법 : 내시경적 또는 경피경간 담관배액술을 통해 담즙을 채취하여 간흡충 충란 유무를 확인한 309명의 췌담과 질환 환자에서 간흡충 감염 실태를 조사하였다. 결과 : 대상 환자 전체의 충란 양성률은 27.5%였고, 남녀의 충란 양성률은 각각 35.%와 17.6%로 남자에서 더 높았다. 연령별 충란 양성률은 30대 20.0%, 40대 26.7%, 50대 24.2%, 60대 29.9%, 70대 36.2% 그리고 80대 이상이 16.7%로 연량에 따른 통계적 차이는 없었다. 질병별 충란 양성률은 담관암 32.65, 담낭암 38.5%, 파터팽대부암 11.1%, 췌장암 24.0%, 담석질환 26.4%,간흡충담관염 61.5% 그리고 이외 질환이 12.5%로 간흡충 담관염ㅇ르 제외한 질병간 의미있는 차이는 없었으며 결석의 위치, 간흡충 연관질환인지 아닌지가 충란 양성률에 영향을 미치지 못했다. 담관 조영술을 포함한 방사선 검사에서 정상 담관을 보인 환자에서 충란 양성률은 17.0%였다. 결론 : 본 연구 결과 울산지역 췌담관 질환 환자에서 간흡충 감염률은 연령, 성별, 질병의 종류에 관계없이 전반적으로 매우 높았다. 따라서 이러한 자료를 근거로 생각해 볼 때 우리 나라가 아직도 심각한 간흡충 감염의 유행지임을 추론할 수 있겠다. Background : Bile examination is believed to be the most precise method for detecting Clonorchis sinesis (CS) eggs. We carried out bile examination to evaluate infestation state of CS in patients with pancreatobiliary diseases in Ulsan, known as an endemic area of CS infestation. Methods : We examined CS eggs in bile in three hundreds and nine patients with pancreatobiliary diseases. The bile was obtained from endoscopic nasobiliary or percutaneous transhepatic biliary drainage tubes. Results : The overall egg positive rate was 27.5% (35.3% in male,17.6% in female). The egg positive rate was not significantly different according to the age group: 20.0% in thirties, 26.7% in forties, 24.2% in fifties, 29.9% in sixties, 36.2% in seventies and 16.7% in eighties or more. The egg positive rate according to the disease, except CS cholangitis, was not also statistically different: 32.6% in bile duct cancer, 38.5% in gallbladder cancer, 11.1% in ampulla of Vater cancer, 24.0% in pancreatic cancer, 26.4% in gallstone diseases and 12.5% in the reminder. The location of gallstone and whether CS related diseases or CS unrelated diseases did not affect the egg positive rates. The egg positive rate in patients with normal radiological findings including cholangiography was 17.0%. Conclusion : This result shows that regardless of age, sex and sorts of diseases, the infestation rate of CS was very high. On the basis of our results, it if therefore presumes that clonorchiasis is still endemic disease in Korea.
