This study was performed to find out the cryoprotectants for cryopreservation of trochophores and early D-shaped larvae of surf clam, Spisula sachalinensis. Dimethyl sulfoxide (DMSO), ethylene glycol, 1,2-propanediol and methanol were used as cryoprotectant Each cryoprotectant was made to 1.0 M, 2.0 M, 3.0 M with dilution of 0.2 M fructose and 0.2 M sucrose. The trochophoers and early D-shaped larvae were immersed in each preparation for 10 minutes to reach equilibration and cryopreserved in liquid nitrogen. Survival rates of post-thawed trochophores and early D-shaped larvae in 2.0 M DMSO with 0.2 M sucrose were the highest as $91.4{\%}\;and\;78.9{\%}$, respectively.

Purpose: To analyse the risk factors for recurrence of hemangiomas in extremities after surgical treatment and to compare with those of trunk. Materials and Methods: 120 cases of hemangioma with surgical treatments from June 1998 to September 2009 were analysed. 53 cases with surgical treatment on trunk in the same period were set to be the control group. We analyze several factors: age, location, site, size, histologic types and correlation between recurrence and each risk factor using logistic regression analysis. Results: Recurrence rate was 11.7% in extremities and 9.4% in trunk. There were no correlation between recurrence and age, site, size, histologic type. But, there was stastically significant correlation between recurrence rate and location, especially hand, forearm, feet in extremities and head and neck in trunk. Conclusion: Recurrence after surgical treatment of hemangioma is highly prevalent in anatomical location such as, hand, foot and forearm those are difficult to achieve complete resection because of close to neurovascular structures. Careful observation should be needed owing to incomplete resection can occurs recurrence.

Purpose: Though caustic injury of the upper digestive tract can lead to severe sequelae, there are few clinical studies on this subject. This study was undertaken to evaluate the clinical characteristics, the endoscopic findings and the risk factors of the upper digestive lesions in patient with caustic ingestion injury. Methods: We retrospectively reviewed the medical records of 137 patients who ingested caustic materials and who visited to our emergency room from January, 2000 to June, 2009. Results: The most common ingested agent was sodium hypochlorite (44.5%), followed by acetic acid (19.7%), hydrochloric acid (11.7%) and lye (8.0%). Ingestion for suicidal attempt (62.0%) was more frequent than accidental ingestion (30.7%). Grade IIa injury was the most frequent finding on endoscopy of the esophagus and Grade 1 injury was the most frequent finding on endoscopy of the stomach. For the late sequelae, there were 9 cases (6.6%) of esophageal stricture and 2 cases (1.5%) of gastric outlet obstruction. The initial signs and symptoms did not correlate with the development of stricture, but leukocytosis, and grade III injury were related to the risk of developing stricture. Conclusion: Caustic injury of the upper gastrointestinal tract is frequently observed on early endoscopy and it can cause significant late sequelae such as stricture. Therefore, it is necessary to evaluate these patients with regular follow up endoscopic examinations for the management of late sequelae.

Since the educational guideline on Information and Communication Technology(ICT) was announced, almost every school has taught about ICT during the discretionary classes. Although research on the computer curriculum and comparative studies on computer textbooks have been conducted, a study on the current status of the use of computer textbooks has not been carried out yet. On the basis of such needs, this study was conducted to investigate the current status of the use of computer textbooks in elementary schools(i.e. how teachers use computer textbooks in schools, and what teachers and students think about computer textbooks), and to suggest ideas to be considered in order to improve the quality of computer textbooks. The main finding of this study is that although most teachers use computer textbooks, the frequency of use is low and teachers use the textbook by revising or complementing its content. Also, most teachers respond negatively to some aspects of computer textbooks(i.e. level-based learning, reconstructional facility, systemicity, enhancement of exploring and creative ability, induction of interest, enhancement of self-directed learning, and assignments). In contrast with this result, students respond negatively only to the vocabularies used in computer textbooks. In addition, teachers showed significantly different responses according to their age and teaching experiences, and students demonstrated significantly different responses according to their gender and the frequency of the use of computer textbooks.

근친에 따른 개체의 능력저하 현상은 다양한 식물과 동물에서 밝혀져 왔다. 재래돼지는 국내 유일 품종이며 소규모 집단으로 유지되고 있어 국가차원에서 중요한 유전자원이다. 본 연구의 목적은 총산자수와 생존산자수에 대한 근교계수, 유전모수 및 근친퇴화 효과를 분석하는 것이다. 국립축산과학원에서 보유한 재래돼지 혈통 2,806두와 483개(1~5산차)의 번식성적을 보유한 모돈 303두의 자료를 활용하였다. 각 형질에 대한 유전모수 추정 후 혼합모형으로 근교계수에 대한 근친퇴화 효과를 분석하였다. 유전모수 추정결과, 총산자수와 생존산자수는 고도의 유전력을 유지하였다. 근교계수는 1998년에서 2017~2018년까지 꾸준히 증가하였으나, 각 형질에 대해 1998년 대비 2017~2018년의 능력감소는 확인되지 않았다. 근교계수 증가에 따라 총산자수의 유의적인 근친퇴화(p=0.03)가 확인되었지만, 생존산자수에서는 유의적인 근친퇴화가 없었다(p=0.41). 또한 두 형질 모두 근교계수와 육종가의 긍정적 상호작용이 확인되었다(p<0.05). 본 연구 결과, 재래돼지 산자수에 대한 근친퇴화 효과가 일부 확인되었지만, 세대가 지남에 따라 명확한 표현형 감소는 확인되지 않았다. 이는 현재까지 높은 유전효과로 근친퇴화를 극복할 수 있음을 시사한다. The reduction in performance due to inbreeding (i.e. inbreeding depression) has long been documented in plant and animal populations. The population of Korean native pigs are small and this breed is valuable in Korea.. This study was aimed to investigate effects of inbreeding depression on total number of piglets born (TNB) and number of piglets born alive (NBA) in Korean native pigs. We used 2,806 pedigree and 303 sows’s data with 483 phenotypic records. After estimating genetic parameters for each traits, inbreeding depression was estimated using a mixed model in which the inbreeding coefficient was included as a covariate. Korean native pigs had high heritability for each traits. Inbreeding coefficient constantly increased from 1998 to 2017~2018 but there is no reduction for each traits in 2017~2018 in compared with those in 1998. Significant inbreeding depression was detected for TNB (p=0.03) but not for NBA (p=0.41). In addition there are significantly positive interactions between inbreeding coefficient and breeding value for both traits (p<0.05). These results suggest that Korean native pigs are still having genetic variation for TNB and NBA, which could overcome reproductive risks from inbreeding coefficient increase.

In this study, the researcher studied the historical background and the traditional culture about dress of Bouyei People of Guizhou Province. The resuits of the study ara as follows. 1. Women`s dress and adorment can be categorized into three styles. In the Zhenning, Guanling and Puding regions and northwestern areas of Guizhou Province, women usually wear blouses with overlapping necks, batik pleated skirts and long aprons. They also wear embroidered kerchiefs or turbans. In the suburbs of Guiyand City and Southwestern Guizhou Province, women like to wear blouses with buttons arranged diagonally on the front, trousers, blue or black and white check cloth kerchiefs. In the Luoping region, women wear blouses with loose sleeves and buttons arranged diagonally on the front and loose-legged trousers. 2. Men usually wear shirts with buttons down the front or arranged on the front, trousers and calottes. 3. Most of their dress materials are white and coloured handwoven, tie-dyed or batik cloth. The exquisite technique of batik and tie-dyeing has a long history, which began to become prevalent in the Song Dynasty. 4. Now, people use all kinds of techniques to make their dress and adornment, including batik, tie-dyeing, cross-stitch, brocade and embroidery, which reflect their peculiar aesthetic temperament.

The aim of this study was to identify the genetic parameters related to leg health and stayability in pigs and discover traits that can be utilized in breeding programs at nucleus farms. We estimated the heritabilities and genetic correlations for several performance traits: standing posture (SP), knee joint (KJ), pastern (PT), claw (CL), and stayability (STAY). The phenotypic records of the test performances and leg conformations of 20,039 and 6,871 pigs, respectively, were evaluated. The heritability ( h² ) was moderate ( h² = 0.15–0.18) for PT, SP, and STAY, and low for CL and KJ. Regarding genetic correlations, SP was strongly positively associated (0.80±0.07) with STAY followed by PT (0.68) and KJ (0.56). For leg conformation traits, SP and PT exhibited relatively high heritabilities of 0.16 and 0.18, respectively. In addition, these two traits showed higher genetic correlations with STAY than the other traits. These findings suggest that SP and PT conformations might be important indicators of improved leg health in pigs. Considering these traits during nucleus breeding selection may enhance sow stayability and increase productivity in pig production systems.

미트라스 숭배의 이란 기원에 관하여

김영신(Kim Young-Sin) 호서사학회 2010 역사와 담론 Vol.0 No.56

In this paper I hope to show Mithras origin. The Mithraic mysteries centered around a secret which was revealed only to those who were initiated into the cult. As a result of this secrecy, the teachings of the cult were never written down. But the Mithraists leaved to posterity a key for unlocking the inner mysteries of their religion. There is one element of the cult's iconography which presented the same form in every mithraeum: the so-called tauroctony, or bull-slaying scene. Attempts by modern scholars to unravel the secret of this bull-slaying scene had taken a path almost as strange as the religion itself, they had been dominated by the work of a single man: the Belgian scholar Franz Cumont. And he interpreted the relationship between dog and snake in the tauroctony as one of intense antagonism, concluding that this was evidence of the presence within Western Mithraism of the primal dualism of Iranian religion. But Hinnells asserts that the dog and the snake go for the eternal blood but they ignore each other. These two figures, therefore, cannot be used as evidence for a dualistic theology of primordial battle. Cumont claimed that the so-called lion-headed god(leontocephaline) whose image was often found in Mithraic temples, represented the Iranian deity Zurvan. However, say Gordon, Cumont simply assumed at every critical point that the Iranian evidence was relevant, and proceeded to argue as though this were an established fact and not merely a working hypothesis. Thus, he concluded that Cumont's Iranian hypothesis was completely invalid. Then, don't we believe Cumont's opinion? But there are contradictions in the many scholars' opinion argued for the Mithras' origin. I think that in the tauroctony the Iranian origin's elements exist. For example, the dog, the snake and the scorpion are important elements in ancient Iranian myth, namely, Bundahishn. And about the bull-slaying scene, I think it has relation to the Yima. Finally, leontocephaline's name also has that of Iranian god. In conclusion, these are able to have Iranian motif. Thus, I think that we are able to acknowledge the Iranian origin of the Mithras cult.
