담관이 폐쇄되었을 때 결장점막내 배상세포의 미세구조적 변화를 알아보기 위하여 체중 2㎏ 내외의 집토끼 총담관을 이중으로 결찰한 후 1일, 3일, 5일,7일 및 14일이 경과한 후, 결장원위부의 조직을 절취하였다. 절취된 조직은 전자현미경 관찰을 위하여 통산적 방법으로 고정, 탈수 및 포매하여 JEM 100CX Ⅱ전자현미경으로 관찰하여 다음과 같은 결과를 얻었다. 1. 결장점막상피를 구성하는 세포중 점액을 분비하는 세포로는 장은와원주세포와 배상세포가 있다. 2. 수술후 3일군의 배상세포의 경우 점액과립중 전자밀도가 낮은 것들은 융합되어 있는 경우가 많았고, 과립형질내세망이 다소 확장되어 있었다. 3. 수술후 5일군에서는 미성숙 배상세포가 많이 관찰되었다. 4. 수술후 7일, 14일군의 배상세포는 점액과립의 생성과 분비양상이 정상세포의 것과 같아 보였다. 따라서 총담관이 결찰되면 초기에는 배상세포의 점액방출 및 생성이 억제되나 시일이 경과되면 배상세포의 분화가 활성화되어 점액의 부족분을 보완해 주어 정상상태로 회복되는 것 같다. This experiment was performed to study the morphological changes of the goblet cells in the rabbit colonic mucosa after common bile duct ligation. Healthy adult rabbits weighing about 2㎏ body weight were divided into normal and bile duct ligated groups. Common bile duct ligation was performed under ether anesthesia. Experimental animals were sacrificed on the 1st, 3rd, 5th, 7th and 14th day after the operation. Mucosal specimens from the distal colon were fixed in 2.5% glutaraldelyde-1.5% paraformaldehyde, followed by 1% osmium tetroxide, embedded in araldite mixture, cut with LHB-V ultratome, stained with uranyl acetate-lead citrate, and observed with JEM 100 CX Ⅱ electron microscope. Observed results were as follow: 1. There were two types of mucous secreting cells in the rabbit distal colon; crypt columnar cell and goblet cell. 2. In the 3rd day after bile duct ligation, there found electron lucent mucous granules in the goblet cell which were occasionally fused together, and moderately distended granular endoplasmic reticulum. 3. In the 5th day after operation, the rabbit colonic goblet cells are frequently seen immature type. 4. In the late stage of the experiments, the rabbit colonic goblet cells showed general findings of the mucous granules, and other cell organells were similar to normal ones. Considering the above findings, common bile duct ligation probably resulted the hypoformation and hyposecretion of mucous granules of goblet cells in the early stage, and may facilitate the differentiation of goblet cells in the late stage.

한국 생산물기원신화의 양상과 성격

권태효(Keown Tea-Hyo) 한국무속학회 2006 한국무속학 Vol.0 No.12

한국에는 다양한 기원신화가 존재한다. 하지만 그 신화적 성격이 약화된 모습이어서 신화로서의 온전한 자리매김을 못하고 있는 상황이다. 이 글은 이런 기원신화들 중 생산물기원신화를 살펴 그 의미와 성격을 살피고자 마련된 글이다. 우리의 생산물기원신화는 곡물기원신화와 해산물기원신화로 구분할 수 있다. 곡물기원신화에 해당되는 자료로는 〈동명왕편〉과 〈삼성시조신화〉, 〈세경본풀이〉 등을 들 수 있으며, 곡물의 기원을 천상을 비롯한 외부로부터 가져오는 형태를 보여준다. 해산물기원신화에 해당하는 신화로는 〈문전본풀이〉를 들 수 있으며, 사체화생형 신화의 모습을 보인다. 이런 우리나라 생산물기원신화의 특징을 정리해보면, 첫째, 문헌 및 구전신화 모두로 전승된다는 점, 둘째, 곡물기원과 해산물기원이 서로 다른 신화 형태를 보인다는 점, 셋째, 곡물기원신화는 목축의 기원 및 직물의 기원을 밝히는 것과도 밀접하게 결합되어 있다는 점, 넷째, 해산물기원신화는 사체화생형 신화 모습을 보이지만 측신의 몸에서 생긴다는 점에서 배설물에서 작물이 생겨나는 형태와 관련이 있다는 점을 들 수 있다. 한편 생산물기원신화는 이웃한 일본에도 『고사기』 와 『일본서기』 등에 다양하게 전승되고 있다. 일본의 생산물기원신화는 우리 신화보다 풍부하고 비교적 온전한 양상을 보여주고 있어, 이런 일본신화와의 비교를 통해 우리 생산물기원신화의 성격 및 기능이 보다 명확해질 수 있을 것이다. 일본의 생산물기원신화를 우리 것과 비교해보면 첫째, 한국의 것은 곡물의 기원을 외부로부터 유입하는 데서 찾는 반면 일본의 것은 배설 및 사체화생에서 기원을 찾고 있어 그 존재양상이나 형태에 있어 차이가 적지 않다는 점, 둘째, 양국의 신화 모두 곡물기원과 더불어 목축기원 및 직조기원이 수반되기는 형태이지만 우리 신화의 경우 목축기원과 긴밀히 결합되는 반면 일본 신화는 직조기원과 더 긴밀히 결합되는 양상을 보인다는 점, 셋째, 우리 것보다 일본의 생산물기원신화가 보다 세부적이고 구체적이며 확장된 양상을 보인다는 점 등의 양상을 보인다. There are various ‘origin’ myths in Korea. Considering their weakened mythical characteristics, it seems the founding myths have not taken right places in the Korean mythology. This paper aims to clarify the meanings and characteristics of a specific kind of myths originated from farm or fishing products and this sort of mythology consists of two parts: crops-based myths and sea products-based myths. Literal references for the former are 〈Dongmyeongwangpyeon〉, 〈Samseongsijosinhwa〉, and 〈Segyeongbonpuri〉 and all of these say that the origin of the crop is from outside world including the heaven. 〈Munjeonbonpuri〉 exemplifies the latter with showing phenomena of the second appearance from deceased bodies. A series of research summarize distinctive features of Korea’s origin myths: 1) the origin myths have handed down literally and orally; 2) crops-based myths and sea products-based myths have different types of mythology; 3)crop-based myths are closely related to the origin of livestock farming and textile manufacturing; 4) sea products-based myths show a common factor of phenomena of the second appearance from deceased bodies and considering a point related to deceased bodies, we can find similar origin that crops are from exudates. Meanwhile this kind of origin myth can be found in some Japanese literarys such as 〈Gosagi〉 and 〈Ilbonseogi〉. Since Japanese orogin myths show more sufficient and intact aspects compared to Korean ones, in order to understand the authentic feature of the Korean products origin mythology, it may be a good way to compare two countries’ products origin myths in a systematic way. A comparative study can bring three major points: 1) while Korean myths seek its origin of crops from outside, Japanese ones do from the deceased body or excretion; 2) it is a common feature that both countries’ mythology accompany livestock farming and textile manufacturing. Closely looking at details, Korean myths have close links to livestock farming, while Japanese ones to textile manufacturing; 3) it is true that Japanese mythology in origin based stories, show more comprehensive and extending aspects than Korean ones.

Whose Job Is It? Parents’ Perspectives on Volunteering to Help in New Zealand Kindergartens

Qilong Zhang,Louise Keown,Susan Farruggia 환태평양유아교육연구학회 2015 Asia-Pacific journal of research in early childhoo Vol.9 No.2

Volunteering to help is a traditional type of parental involvement in early childhood education. There have been concerns over the justification of teachers’ practice of leaving their work with parents, particularly for routine tasks such as washing and cleaning, however, little research has been conducted to scrutinize the practice and examine parents’ experiences with volunteering to help. Based on a sample of 25 parents from New Zealand public kindergartens, this study investigates parents ‘experiences with three types of volunteering to help at the kindergarten. Analysis of the semi-structured interview data has revealed enhancers (e.g., benefits for the child, justification of fundraising) and impediments (e.g., limited time, school commitment) to parent volunteering to help as well as the tensions in practice(e.g., relying on core parents, limited resource). The findings support the legitimacy of routine tasks and fundraising and highlight the importance of parent volunteering to help.

형태 표현을 이용한 3-D 물체 인식

김순자,하영호,권오주,정인갑 경북대학교 전자기술연구소 1993 電子技術硏究誌 Vol.14 No.1

The 3-D object recognition is related to the representation of the range data and the matching method of the correspondence. In this paper, we propose the recognition method using fuzzy data-base that reduces the amount of computation and has simple expression of an object. These fuzzy shape representations describe the linguistic primitives of the various objects. The recognition system for synthetic range image produces 2-D and 3-D description of the objects. Matching between the objects and the model is performed by three steps : the grid matching, local matching using fuzzy data, and global matching. The proposed method has advantage of simple object representation and model-base matching computation.

Estimation of Genetic Parameters for Direct, Maternal and Grandmatemal Genetic Effects for Birth, Weaning and Six Month Weights of Hanwoo (Korean Cattle)

Choi, S.B.,Lee, J.W.,Kim, N.S.,Na, S.H.,Keown, J.F.,Van Vleck, L.D. Asian Australasian Association of Animal Productio 2000 Animal Bioscience Vol.13 No.2

The objectives of this study of Hanwoo (Korean Cattle) were 1) to estimate genetic parameters for direct and maternal genetic effects for birth weight, weaning weight, and six months weight which can be used for genetic evaluations and 2) to compare models with and without grandmatemal effects. Data were obtained from the National Livestock Research Institute in Rural Development Administration (RDA) of Korea and were used to estimate genetic parameters for birth weight (BW, n=10,889), weaning weight at 120-d (WW, n=8,637), and six month weight (W6, n=8,478) in Hanwoo. Total number of animals in pedigrees was 14,949. A single-trait animal model was initially used to obtain starting values for multiple-trait animal models. Estimates of genetic parameters were obtained with MTDFREML using animal models and derivative-free REML (Boldman et al., 1995). Estimates of direct heritability for BW, WW, and W6 analyzed as single-traits were 0.09, 0.03, and 0.02 from Model 3 which included direct and maternal genetic, maternal permanental environmental effects, and effects due to sire ${\times}$ region ${\times}$ year-season interaction, respectively. Ignoring sire ${\times}$ region ${\times}$ year-season interaction effect in the model (Model 2) resulted in larger estimates for direct heritability than for Model 3. Estimates of maternal heritability for BW, WW and W6 were 0.04, 0.05, and 0.07 from Model 3, respectively. The estimates of direct-maternal genetic correlation were positive for BW, WW, and W6 with Model 3 but were negative with Model 2 for WW and W6. Estimates of direct genetic correlations between BW and WW, BW and W6, and WW and W6 were large: 0.52, 0.45, and 0.90, respectively. Genetic correlations were also large and positive for maternal effects for BW with maternal effects for WW and W6 (0.69 and 0.74), and even larger for WW with W6 (0.97). The log likelihood values were the same for models including grandmatemal effects as for models including maternal effects for all traits. These results indicate that grandmatemal effects are not important for these traits for Hanwoo or that the data structure was not adequate for estimating parameters for a grandmatemal model.

Interactions between Drosophila USP and ECR - A in Yeast Using the Two - hybrid System

Lee, Chung Choo,Kim, Se Jae,Chung, Ki Wha,Park, Ji Keown,Ko, In Sook 한국유전학회 1996 Genes & Genomics Vol.18 No.4

ultraspirade gene product (USP) is one of several orphan receptors in Drosophila, sharing significant homology with the mammalian retinoid X receptor. In Drosophila the response to the hormone is mediate in part by USP and ecdysone receptors (ECR), which are members of the nuclear receptor superfamily. Heterodimers of these proteins bind to ecdysone response elements (EcRE) and ecdysone to modulate transcription. We used the yeast two-hybrid assay for detection of protein-protein interactions in vivo to screen for novel partners of USP. The GAL4 DNA-binding domain fused to USP was used as bait to screen a Drosophila embryonic cDNA library in which the cDNA was fused to the GAL4 activation domain. Several cDNA clones encoding proteins that interact with USP were isolated, one of which corresponded to the ecdysone receptor A isoform (ECR-A). Domain analysis on USP revealed that the ligand binding domain is required for heterodimerization with ECR-A. Given the ability of USP to dimerize preferentially with ECR-A, this strategy should be useful for cloning novel partners for USP from a variety of cell types.

It has been well established that glomus tumors may exist in any part of the body. Glomus tumor of the stomach is very rarely found. The most common initial symptom is gastric bleeding and other clinical manifestations are indigeston, nausea, vomiting, constipation and weight loss. In most cases, glomus tumor behaves in a benign fashion but malignant gastric glomus tumor with metastasis has been reported. The diagnosis is not easy, because this tumor is mistaken for certain benign gastric lesions and polyps. Final diagnosis can be made by histopathologic findings of the tumor mass. The authors report a case of gastric glomus tumor with a literature review.
