Two farmed young ostrich chicks were applied to pathology laboratory at Chungnam National University. Grossly, one ostrich showed rotated tibiotarsus, the other showed rolled toes. Case 1 ostrich was hypertrophy of fibualis longus and tibial cranialis tendon and gastrocnemius tendon in crus, inflammation of flexor digitorum longus. In histopathological views, myocytes of fiburalis longus were showed hypertrophy and hyperplasia. It is not found any specific feature in X-ray of the case 2 ostrich. Limb deformities were detected frequently in farmed ostrich chicks in 2- to 3 weeks old. Limb deformities were an important cause of mortality in farmed ostrich chicks during the first 10weeks after hatch. Cause of limb deformities were considered a nutrition problem.

Up to now, analyses of the precision in A.T, have been dealt with hypothesis of error-free on ground control coordinates. In fact, it is not error-free but the precision of ground control surveying is higher than the precision of aerotriangulation. In this investigation, it has, therefore, given weight corresponding to precison of the ground control surveying, and it has analyzed the influence which the precision of ground control coordinates exerts upon the absolute error of check points with the change of the control spacing. Then, the results of this investigation can be concluded as follows: (1) In weight 10^1 case, it has known that ground control coordinates have been permitted error-free. (2) It is thought that it will be desirable to give the corresponding weight when the precision of ground control surveying is had. (3) The absolute error goes to bad with the change of control spacing from 2 models to 4 models. Therefore, it is known that the control spacing influences the absolute error.

In conjunction with a vertical network, horizontal geodetic control points provide the basic framework for topographic mapping and legal survey. The design of such networks as well as the technical means for obtaining their coordinates have been changed in time, and therefore National Geographic Institute has planned and observed the precise geodetic network since 1975. The aim of this study is to investigate the systematic distortions of the precise primary geodetic net in Korea implementing by the simultaneous adjustment. Another aim is to study basic scheme for determination of official coordinates of geodetic control points.

This study is carried out the analysis for the transformation of an overland runoff in urban areas with the progress of urbanization, Urbanization concerned with the concentration of population. activity and expanding the urban area changes a natural environment, and human activity in urban area causes the appearance of a new hydrologic cycle system. This studies defined the concept of urban environment and the role of rivers and investigates the change of natural environment caused by the civilization of urban area, the change of recharge from a surface flow for the fluxing characteristics in urban river, and the flux for suggesting the organization system of a surface flow in urban river. From the analysis of the rainfall-runoff processes in small urban area with the progress of urbanization, the following conclusions is obtained, It is found in the result of calculated geographical parameter that concentration time is quickened by 20-25 minutes rather than the urbanization before. Also, in the analysis of the peak rate of runoff, the peak discharge rise by 6% than the urbanization before.

This treatiese is to provide basic data to contribute to development of our textiles industry by introducing the representing textiles of each times under the studying scope from the ancient times to the Japanese textiles which is culturally neighboring country upon recognition of imporance of the material in fashion. The chronological changes and characteristic style of Japanese textiles are as follows : 1. The origin of textiles in Japan was about 300 years B.C. When the tillage culture was about to begin and the yarn in Jomon(繩文 時代) period was coarse enough which used of bark tress and the faber in Yayoi period(彌生 時代) plan textiles made by cotton fiber now on exhibition. 2. In Aska period(飛鳥 時代) as it was origin of the Japanese art and there were consecutive grid flory pattern, tortoise skin & flower pattern, lion & phoenix pattern's Dokganggeum(獨江錦) 3. In Nare period(奈良 時代) which was golden age in the Japanese history the silk fabric was especially developed and Chinese grass pattern(唐草 文樣) under-tree animal pattern(樹下動物 文樣) and woonkan pattern(量澗 文樣) were the main stream therof. The "lion-tooth pattern silk with speckles"(獅子 齒文 長班錦) of the Seiso-In Hall. 4. In Heian period(平安 時代) the diplomacy with the continent was lessened and the Japanese own culture was formed and the ceremorial costume which emphasized style and color and beauty Some krido of Brocades in Nara period for weaving patterns were "tiger pattern silk under tea tree" of the Seiso-In Hall.

본 연구는 학교 주5일제에 관한 학생과 교사의 의식을 조사분석하여 학교 주5일제 실시에 대응하고자 하였다. 조사 대상자는 초·중·고 학생 1558명과 교사 1077명이었다. 연구결과, 학생들은 현재 학교생활에서 공부하는 즐거움을 알지 못하고 친구들과의 교제에서 즐거움을 찾고 있는 것으로 나타났다. 학교 주5일제 관해서는 학생과 교사 대부분이 찬성하고 있으며, 찬성 이유는 여유있는 하루, 가족과 접촉시간을 갖고 취미활동을 하며 친구와 놀 수 있기 때문이라고 하였다. 교사들은 학교 주5일제로 인한 수업시수의 문제를 감축해도 상관이 없다는 반응이 많았고, 현재의 수업시수를 확보해야 한다는 의견은 적었다. 학생과 교사 대부분은 학교 주5일제는 학생들이 다양한 체험을 할 수 있는 기회를 제공하는 체제로 인식, 긍정적인 반응을 보였다. The purpose of this study is twofold: (ⅰ) to analyze students and teachers' consciousness on the proposed Five-day-work-week School System(FSS) plan; and (ⅱ) to propose a desirable direction of school management including curriculum compatible with the (FSS) plan. This study developed as follows. For the theoretical background of this study, previous research was reviewed. For the items of the questionnaire, the Japanese Ministry of Education Survey on the FSS at school was referred to. The Subjects sampled were 1558 students and 1077 teachers, The data collected from the at elementary, secondary and high school of students and teachers were statistically analyzed by using the SPSS WIN 7.5. The following are the results of the survey. First, in order to adopt the FSS plan, schools have to develop new programs connecting home and school. It is required that school develop special programs that the local community can participate in and cooperate with. Second, most of the respondents support the FSS plan because students can have more chances to be with their family, to become familiar with nature, and to attend various activities sponsored by the local organizations. Third, to argue that it is desirable to adopt the FSS plan even though school has to reduce the minimum class hours. The reason they are against the no-school-on-saturday plan is that there are many families who cannot take care of their children on Saturdays; thus, special programs for them should be prepared before the plan is put into practice. It is also required that we develop various sports or culture events for young adolescents and make up more organizations for youth. We should have school or community facilities open to young adolescents and children whose parents are unavailable to care for them. The latter should have an easy access to those facilities. From these observations, we can conclude that it is imminent to develop various programs before we put the FSS plan into practice. Schools should cooperate fully with homes and the community.

Background : CD14 is the receptor for lipopolysaccharides and heat shock protein (HSP), which has been suggested being associated with increased risk of coronary artery disease (CAD). We investigated whether the response to infectious agents or HSP is different according to CD14 polymorphism in Koreans. Materials and Methods : Antibody titers to Helicobacter pylori, Chlamydia pneumoniae, and human HSP60 (hHSP60) were measured in 48 patients with stable CAD and in 41 healthy controls by ELISA. CD14 genotype was determined by PCR and high-sensitivity C-reactive protein (hs-CRP) was measured. Results : Seropositivity to C. pneumoniae and H. pylori, and antibody titer to hHSP60 were not significantly associated with the presence of CAD. CD14 genotype distribution was 31 TT (35%), 43 CT (48%), and 15 CC (17%). To compare the response to the infectious organism and hHSP60, we divided study population into 3 groups; CAD patients with non-TT genotype (group I, n=30), CAD patients with TT genotype (group II, n=18), and normal controls (group III, n=41). Seropositivity to C. pneumoniae and H. pylori, and antibody titer to hHSP60 were not significantly different among 3 groups. Though hs-CRP level was significantly different among 3 groups, post-Hoc analysis showed that hs-CRP level was not significantly different between group I and group II (group I: 1.6[1.1-3.5] mg/L and group II: 0.35[0.1-2.0] mg/L). Conclusions : This study suggests that the inflammatory responses to infectious organisms and HSP do not differ according to the CD14 genotype in Koreans. 목적 : 만성적인 세균 감염이나 자가 면역 반응이 동맥경화와 연관되어 있다는 주장이 제기되어 왔다. CD14은 lipopolysaccharides (LPS)와 heat shock protein(HSP)의 수용체로 C(-260)→T 다형성이 관상동맥 질환의 위험과 관련되어 있다고 제안되어 왔다. 본 연구에서는 한국인에서 CD14 다형성에 따른 LPS와 HSP에 대한 반응성을 염증표지자를 측정하여 살펴보고자 하였다. 재료 및 방법 : 안정형 관상동맥 환자 48명과 정상 대조군 41명을 대상으로 Chlamydia pneumoniae, Helicobacter pylori 항체 및 인체 HSP60 (hHSP60) 항체 역가를 enzyme-linked immunosorbent assay (ELISA) 방법으로 측정하였다. CD14 유전자형은 중합효소연쇄반응을 이용하여 결정하였고 hs-CRP를 측정하였다. 결과 : C. pneumonias 및 H. pylori 항체 양성 여부 및 항체 역가, 그리고 hHSP60에 대한 항체 역가는 안정형 관상동맥 질환의 유무와 유의한 상관관계는 없었다. CD14 유전자형의 분포는 TT 30명(39%), CT 31명(40%), 그리고 CC 16명(21%)이었다. 관상동맥 질환 군에서 TT 유전자형은 38%, 대조군에서는 32%로 TT 유전자형과 관상동맥 질환의 유무와는 유의한 상관관계가 발견되지 않았다(P>0.05). CD14 유전자형에 따라 C. pneumonias와 H.pylori 감염 및 hHSP60에 따른 반응에 차이가 있는지 여 부를 알아보기 위해, 관상동맥 질환 군을 다시 TT 유전자형 군과 non-TT 유전자형 군으로 나누어, 전체적으로 세군에서 항체 양성률과 역가를 비교하였다(I군: CD14 TT 유전자형을 가진 안정형 관상동맥 환자, II군: CD14 TT 유전자형을 가진 안정형 관상동맥 환자, III군: 정상 대조군). 세 군에서 C. pneumonias와 H. pylori 항체 양성률 및 hHSP60 항체 역가에는 유의한 차이가 없었다. 세 군사이에 hs-CRP 값에 유의한 차이가 있었지만, post-Hoc분석에서 II군의 hs-CRP 값이 I군에 비해 유의하게 높지는 않았다(0.35 [0.1-2.0] mg/L in group II vs. 1.6 [1.1-3.5]mg/L in group I, P>0.05). 결론 : 본 연구는 한국인에서 CD14 유전자형에 따라 LPS나 HSP에 대한 반응이 유의하게 다르지 않음을 시사한다.

Pilomatricoma was histopathologically diagnosed in a 2.5-year-old male Alaskan malamute. The patient was referred to Chungnam National University, Veterinary Medical Teaching Hospital with solitary, firm and well-circumscribed mass at shoulder. Grossly, the mass was dome shaped to tumor like and 10 x 8 x 5㎝ in size. Some lesions had gritty or bony consistency and was chalky when sectioned Histopathologic feature included mumerous clusters of tightly arranged, basaloid cells with evenly distributed chromatin and ghost cells were characterized by a central unstained zone. The ghost cells often become calcified and osseous metaplasia was also present.

Sulfadimethoxine (SM) is one of the anti-thyroid (goitrogenic) agents and has a thyroid tumor promoting effects. In this study, we analyzed the pathology of SM induced thyroid proliferative lesions to see if these lesions showed any distinctive features. Five-week-old male F344 rats were given a single subcutaneous injection of N-bis(2-hydroxypropyl)nitrosamine (DHPN: 2800㎎/㎏, body weight). Starting one week thereafter, SM (1000 ppm in drinking water) was administered for 12 weeks. All animals were autopsied and histopathological observation of the thyroids was perfomed. Thyroid follicular proliferative lesions were induced in all rats treated with SM. In addition, the formation of thick perithyroidal fibrous capsule and pleomorphic follicles within the capsule were observed. These pleomorphic follicles showed invasive figure in some area, especially around follicular adenomas and adenocarcinomas. This confuses adenoma with adenocarcinoma. However, pleomorphic follicles were also observed in the area without adenomas and adenocarcinomas. Therefore, we suggest that it should be careful to diagnose adenoma and adenocarcinoma in the presence of the invasive lesions in surrounding fibrous tissue, especially SM induced thyroid lesion.
