We priority given to Jowoo-Kwan this study examined the ideologic backgrounds which had influences on Jowwo-Kwan throughout the Birds Worship Thought and the Yin-Yang and Five-Elements Thought. Jowoo-Kwan with bird-feathers to Jeol-Poong namely the orgin of the Korean Kwan-Mo existed as a northern cultural elements until the Three States. The customs of Joo-Kwan were greatly related to the hunting life of a horse-riding people and they were dominated the Birds Worship Ideology originated from the primitive religion of a northern people namely Shamanism. In the early days Jowoo-Kwan with natural bird-feathers was decorated with golden bird-feathers with the development of a so-ciety and it changed realistic and crative in the form. The results that Jowoo-Kwan is applied to the Yin-Yang and Five-Elements Thought as follows. The Higher front part represents Yang and on the other hand the lower back part does Yin. Thus Jo-woo-kwan consists of a ideologic Yin-Yang. By means of principles of the Five Elements Birds are included in four animals with the mean of God and especially we can confirm it from a red bird. Expresions of Jowoo-Kwan shows the influences of the Five Elements thought.

Reproduction and molt are costly processes in avian life histories. These two fitness-related traits are expected to be under one of physiological trade-offs. Age-related molt is known to be higher in young birds than that in adults presumably due to the cost of reproduction in adults. The present study partially replicated a previous study using a non-invasive method of seasonal wing feather loss instead of capture-inspection for molting progress in oriental storks (Ciconia boyciana). We first examined characteristics of the known six wing feather types (i.e., primaries [P], primary coverts [PC], secondaries [S], secondary coverts [SC], and tertials [T]) from two specimens with four wings. Results were utilized as references for further investigation. We then collected a total of 3,807 wing feathers shedded by 61 captive storks for one year and classified them into six wing feather types based on the reference with structures of vane (i.e., how asymmetrical) and calamus (i.e., how rigidly attached to skin) of wing feathers. Our results indicated that annual losses of all six-type wing feathers decreased with increasing ages, ranging from 29% to 58% for PC, alula, SC, P, S, and T in order. Our results were also comparable to those of a former study, suggesting that the pattern of age-specific molt might be associated with the cost of reproduction in adults. However, juveniles might shed more wing feathers with low quality formed during the previous development stage than older birds.

집비둘기는 도시지역에서 환경오염물질의 생물축적 모니터링을 위한 지표종으로 알려져 있으며, 집비둘기 알은 생물 자체를 죽이지 않고도 생물축적의 경향을 모니터링할 수 있는 시료로서 유용하다. 하지만 알은 유기 오염물질 축적은 잘 되는 반면, 납, 카드뮴 같은 특정 중금속은 저농도로 축적되는 특성이 있기 때문에 중금속에 대한 적절한 모니터링을 위해 대체 시료의 연구가 필요하다. 이에 본 연구에서는 집비둘기의 세척깃털을 이용하여 중금속 축적 특성을 연구하였고, 중금속 모니터링 시료로서의 가능성을 검토하였다. 도시지역인 서울 한강공원과 농촌지역인 함평군 함평공원을 대상으로 2013년 4월~5월에 집비둘기 개체 포획 및 알 채집을 실시하였고, 생체 조직, 세척깃털, 알의 중금속 5종(Pb, Cd, Total Cr, Ni, As)에 대한 축적 농도를 분석하였다. 중금속 5종의 생체 조직 내 축적 특성을 보면, 납(Pb)과 카드뮴(Cd)은 나머지 3종(Total Cr, Ni, As)에 비해 생체 조직 내 축적이 두드러지게 높게 나타났다. 특히, 납은 다른 중금속에 비해 지역 간 비교에서도 두드러진 농도 차이를 보였는데, 뼈, 간, 혈액에서 통계적으로 유의하게 농촌지역인 함평공원보다 도시지역인 한강공원이 높은 농도를 보였다. 이러한 경향은 깃털에서도 나타났다. 알 시료(알 내용물, 껍데기)는 깃털보다는 상대적으로 낮은 농도로 납이 축적되는 경향을 보였다. 깃털 중에서는 꼬리깃과 날개깃이 각각 신장 및 뼈 조직의 납 농도와 통계적으로 유의한 양의 상관관계를 보였다. 이상의 결과로 볼 때, 중금속 배출경로 요소(깃털, 알, 배설물 등) 중 하나인 깃털로 축적되는 납 농도는 다른 요소(예: 알)에 비해 상대적으로 높고, 환경 오염요소(대기, 토양, 먹이 등) 내 납 농도가 서로 차이나는 지역들 내의 집비둘기의 생체 축적농도 차이를 깃털이 어느 정도 반영할 가능성이 있을 것으로 판단된다.

This article reports a spontaneous thoracic teratoma in a laying hen (Deklb brown warren). In this case, a 40 days old hen was submitted for necropsy as part of an investigation into a flock problem suspected Marek's disease to Chonbuk Veterinary Service Laboratory in 1983. On the gross finding, mass was In the cranial subpulmonary cavity and attached to the vertebral column. It contained fully developed contour feathers. Histologically, feathers were arised from feather follicles complete with arrector plumi muscle, nerve, vessel and mucous gland composed with simple tall columnar epithelium. The outer surface of mass was lined by keratinized or nonkeratinized stratified squamous epithelium. It converted to pseudostratified ciliated columnar epithelium in some area. There were lymphocyte infiltration around gland tissue and eosinophilic intranuclear inclusion bodies in nonkeratinized epithelium. This thoracic teratoma was composed of ectodermal origin, squamous epithelium and nerve, and endodermal origin, mucous gland. This case in laying hen has never been reported in the literature in the world.

Objectives : This study was performed to assess the community capacity building ability of health promotion workers of public health centers and to identify influential factors to the ability. Methods : The subjects were 43 public officers from 16 public health centers in Busan Metropolitan City. Questionnaire was developed based on 'Community Capacity Building Tool' of Public Health Agency of Canada which consists of 9 feathers. Each feather of capacity was assessed in 4 point rating scale. Univariate analysis by characteristics of subjects and multivariate analysis by multiple regression was done. Results : The mean score of the 9 features were 2.35. Among the 9 feathers, 'Obtaining resources' scored 3.0 point which was the highest but Community structure scored 2.1 which was the lowest. The mean score of the feathers was relatively lower than that of Canadian data. The significant influential factors affecting community capacity building ability were 'Service length', 'Heath promotion skill level', 'Existence of an executive department', and 'Cooperative partnership for health promotion'. According to the result of multiple linear regression, the 'Existence of an executive department' had significant influence. Conclusions : Community capacity building ability of subjects showed relatively lower scores in general. Building and activating an executive department and cooperative partnerships for health promotion may be helpful to achieve community capacity building ability.

Blood samples were collected from eight native Japanese breeds of chickens (Miyadi-dori, Ohiki, Onaga-dori, Shoukoku, Tosa-Jidori, Tosa-Kukin, Toutenkou and Uzurao) and two foreign breeds of chickens (White Leghorn and Rhode Island Red) to examine the genetic variability and relationships among the breeds by using a microsatellite DNA technique. Except for the Shoukoku breed, the other Japanese chicken breeds all originate from Kochi Prefecture. Ohiki, Onaga-dori, Tosa-Jidori, Toutenkou and Uzurao are fancy fowl, and Miyadi-dori and Tosa-Kukin are utility fowl. Among the fancy fowl, Ohiki, Onaga-dori, and Toutenkou males have thick and long feathers in the saddle and tail. Genetic variabilities of the 20 microsatellites examined, varied depending on the breed: the mean number of alleles per locus ranged from 2.05 (Miyadi-dori) to 3.90 (Rhode Island Red); proportion of polymorphic loci ranged from 0.75 (Miyadi-dori) to 1.00 (Rhode Island Red, Shoukoku and Uzurao); and mean expected heterozygosity ranged from 0.330 (Miyadi-dori) to 0.607 (Rhode Island Red). Unique microsatellite alleles were detected in each breed. Using the neighbour-joining method, phylogenetic trees were constructed based on the genetic distances of D$_{A}$ and D$_{ST}$. Among the breeds originating from Kochi Prefecture, fancy and utility breeds belonged to different clusters. Among the fancy breeds, those having thick and long feathers in the tail and saddle showed a close genetic relationship to the Shoukoku breed, which also has thick and long feathers in the tail and saddle.

A mathematical model has been constructed to estimate the amino acid requirements for growing Taihe silky fowls in early stage. A requirement was taken as the sum of the needs for maintenance, for gain in carcass weight without feathers, and for the feathers. The maintenance requirement was considered to be the sum of the needs for replacing skin and intestinal losses and for the obligatory creatinine excretion in the urine. A comparative slaughter trial and nitrogen balance trials with growing and adult Taihe silky fowls, respectively, were conducted to estimate the parameters in the model. The amino acid requirements were then calculated with the constructed models. The results showed as following: the replacement needs for skin nitrogen loss was determined at 213.41 mg/d for adult male fowls (body weight 1.60 kg); creatinine excretion in these birds was 4.04 mg/d. when fed an nitrogen-free diets, the adult male fowls with body weight 1.60 kg excreted a total of 246.10 mg/d endogenous nitrogen. The net protein requirement for maintenance was estimated at $11.24mg/w_g{^{0.75}}/d$Per gram of body weight gain contained 27.18 mg carcass nitrogen for growing birds in early stage, but feathers nitrogen in per gram of body weight gain increased with age. The amino acid requirements for growing Taihe silky fowls were slightly higher than for starting and growing pullets, but lower than that of broiler chicks. The amino acid requirements patterns changed with weeks of age.
