Myung‐Jin Lee,Gi‐Hoon Jung,Soon‐Ju Kang 대한임베디드공학회 2006 대한임베디드공학회논문지 Vol.1 No.2

A home network is a typical ubiquitous computing network that consists of various consumer devices and service environments. Home networks are requiring increasingly more complicated services, such as multimedia home theater and the monitoring and controlling of heterogeneous devices. Accordingly, a mutually connecting mechanism is needed among heterogeneous devices and services redundant. The current paper presents a Multimedia Room Bridge Adapter (MRBA) system that is designed to manage heterogeneous devices and support various services. In addition, a hardware and software prototype is implemented based on the proposed architecture.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

강진한,최진영,이종호,정필훈,김명진 대한악안면성형재건외과학회 2000 Maxillofacial Plastic Reconstructive Surgery Vol.22 No.5

Until recent time many studies for relationship of dental abnormalities and cleft lip and palate were reported, higher prevalence of abnormality was revealed. The patients with large cleft size had significantly more missing teeth than patients with small cleft size. The tooth that is most usually missed in normal population is the mandibular second premolar, followed by the maxillary lateral incisor and the upper second premolar. The aim of this study was to analyse the prevalence of dental abnormalities and ectopic eruption in patients with cleft alveolus visiting our hospital. Radiographs, dental cast and records from about 60 patients were analysed to find the relation of missing, malformed, malpositioned tooth and delayed eruption and cleft site.

Purpose : The purpose of this study was to develop a stent-based image guided surgery system and to apply it to oral and maxillofacial surgeries for anatomically complex sites. Materials and Methods : We devised a patient-specific stent for patient-to-image registration and navigation. Threedimensional positions of the reference probe and the tool probe were tracked by an optical camera system and the relative position of the handpiece drill tip to the reference probe was monitored continuously on the monitor of a PC. Using 8 landmarks for measuring accuracy, the spatial discrepancy between CT image coordinate and physical coordinate was calculated for testing the normality. Results : The accuracy over 8 anatomical landmarks showed an overall mean of 0.56±0.16 mm. The developed system was applied to a surgery for a vertical alveolar bone augmentation in right mandibular posterior area and possible interior alveolar nerve injury case of an impacted third molar. The developed system provided continuous monitoring of invisible anatomical structures during operation and 3D information for operation sites. The clinical challenge showed sufficient accuracy and availability of anatomically complex operation sites. Conclusion : The developed system showed sufficient accuracy and availability in oral and maxillofacial surgeries for anatomically complex sites. (Korean J Oral Maxillofac Radiol 2009; 39 : 149-56)

Objectives: This study examined the relationship of fatigue to medical utilization, occupational accident and sickness absence. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project, 2002~2004). A total of 30,146 employees categorized within the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were recruited. A structured-questionnaire was used to assess the participants' sociodemo-graphics, job-related factors, health-related behaviors, personality trait, self=perceived fatigue (MFS) and the frequency of medical utilization, occupational accident and sickness absence. Data on medical utilization and occupational accident were confirmed from company health records. Chi-square test and logistic regression analysis were used to elucidate the relationship of self-perceived fatigue to medical utilization, occupational accident and sickness absence. Results: In logistic regression analyses, self-perceived fatigue was associated with medical utilization (outpatient), occupational accident and sickness absence although the strength of the associations was higher in the blue collar workers except for medical utilization. For medical utilization, the white collar worker's adjusted odds ratios of outpatient utilization for workers scoring in the third quartile and the highest quartile, compared to workers scoring in the lowest quartile were 1.50 (95% CI: 1.20-1.87) and 2.16 (95% CI: 1.69-2.75), respectively. The blue collar workers' adjusted odds ratios of outpatient utilization for workers scoring in the second (OR: 1.23, 95% CI: 1.06-1.43), third (OR: 1.42, 95% CI: 1.22-1.66) and highest quartile (OR:1.83, 95% CI: 1.55-2.17), respectively, compared to workers scoring in the lowest quartile were statistically significant. However, no associations were found between fatigue and inpatient utilization for either the white or blue collar workers. The blue collar workers' adjusted odds ratios of being injured for workers scoring in the second, third and highest quartile were 1.41 (95% CI: 1.00-2.00), 1.57 (95% CI: 1.10-2.22) and 2.41 (95% CI: 1.69-3.44), respectively, compared to those scoring in the lowest quartile, but, those of the white collar workers were not significant. There was more likely to an increased risk of sickness absence in workers scoring in the second, third and highest quartile compared to those scoring in the lowest quartile in both white and blue collar workers, but the magnitudes of risk were higher in the blue collar workers than the white collars workers. Conclusion: This result suggests that fatigue is a determinant predictor of medical utilization, occupational accident and sickness absence, and that the pattern of risks for the three outcomes differs according to the occupational type. Some limitations of this study and considerations for future study were also discussed.

홍민어 Sciaenops ocellatus에서의 바이러스성 신경괴사증 viral nervous necrosis

김진도,김석렬,정성주,김영진,정태성,최태진,박성우,오명주 한국어병학회 2001 한국어병학회지 Vol.14 No.2

1999년 10월에서 11월 사이에 남해안 일대의 홍민어 종묘 생산장에서 20~30열령의 치어가 척추만곡 및 이상유영을 하며 대량 폐사하였다. 병어는 특이 외부 증상이 없었고, 높은 누적폐사량이 바이러스 질병으로 의심되어, 조직학적 및 분자생물학적인 검사를 행하여 폐사원인을 확인하였다. 폐사개체의 조직을 H-E 염색하여 관찰한 결과 뇌와 안구의 신경세포에서 공포와 괴사가 관찰되었고, 전자현미경 관찰에서는 안구와 뇌에서 바이러스 입자가 관찰되었다. RT-PCR 결과에서는 ≒426 bp의 DNA 단편을 확인할 수 있었다. 이러한 결과로 홍민어에서 발생한 대량폐사는 바이러스성 신경괴사증(VNN)으로 진단되었다. Mass mortalities occurred among red drum lavae, 20 to 30 days old, culturing at hatcheries on southern costal area. No specific external signs were observed except abnormal swimming and spinal deformity. It was, however, suspected as a viral etiology due to high mass mortalities so that histopathological and molecular biological study was performed to evaluate the agent. Both vacuoles and necrosis were observed on nerve cells of brain and eye by H-E staining, and viral particles were observed on electronmicroscopic examination. On the other hand, DNA fragment, approximately 426 bps, was amplified with RT-PCR. The above results were able to diagnosis the etiological agent of mass moralities in red drum larvae as VNN(viral nervous necrosis)virus.

『주역참동계』에 나타난 의학사상 연구

임명진 ( Myung Jin Im ),김병수 ( Byung Soo Kim ),강정수 ( Jung Soo Kang ) 대한한의학원전학회(구 대한원전의사학회) 2011 대한한의학원전학회지 Vol.24 No.5

According to 『Dongeuibogam(東醫寶鑑)』, 『the Shinnong Herb Bible(神農本草經)』, 『Chamdonggo(參同攷)』, come to the conclusion about medical thought of 『the Zhouyi Cantongxie(周易參同契)』. Alchemy is a common field both on the eastern and western civilization, but a process of development is different. Ancient chinese alchemist made a study on external alchemy, but harmful consequences of external alchemy was consecutive, many scholars had turned their interest on internal alchemy which is related in human meridian biology and spirit. In the western alchemy has developed to make a study on analytic psychology and science of religion. Most importantly, the eastern and western alchemy have something in common what at the point of the perfection of self is similar, but the name is different, for example in the eastern alchemy we can be immortals and take a spiritual enlightenment with the elixir of life, in the western we can take a cure of souls as a christian. As for internal alchemy, 『Cantongxie(參同契)』 gives influence to the theories such as the theory of danjeon(lower part of the abdomen), evolution, aging, and life nurturing. Especially, the theory of danjeon shows such merit for studying since it is similar to triple energizers(三焦) and the theory of qi street(氣街) of oriental medicine. The study on 『Cantongxie(參同契)』 was achieved in Korea too, especially Chosun dynasty. 『Candongkao (參同攷)』 by Seo Myung-eung(徐命膺, 1716~1787) are representative. According to 『Candongkao(參同攷)』, Geon(乾), Gon(坤), Gam(坎), and Ri(離), the four trigrams for divination, each are affiliated with lungs, spleen, kidneys, and heart. Nowadays the study on alchemy correspond with modern trends, which are anti-aging and living without any disease. If processed mineral drugs is assured for stability, it can be used for incurable diseases such as cancer.

Methylation Status and Expression of E-cadherin in Oral Squamous Cell Carcinomas Compared to Benign Oral Epithelial Lesions

Son, Hyun-Jin,Chu, Jung-Youb,Cho, Eui-Sic,Lee, Dong-Geun,Min, Myung-Gee,Lee, Suk-Keun,Cho, Nam-Pyo The Korean Academy of Oral Biology 2006 International Journal of Oral Biology Vol.31 No.2

Expression of invasion/metastasis suppressor, E-cadherin, is reduced in many types of human carcinomas. Although somatic and germline utations in the CDH1, which encodes the human E-cadherin, have frequently been reported in cases with diffuse gastric and lobular breast ancers, irreversible genetic inactivations are rare in other human carcinomas. Recently, it has been well documented that some genes in human cancers may be inactivated by altered CpG methylation. Herein, we determined the expression and methylation status of E-cadherin in oral squamous cell carcinoma (SCC) by immunohistochemistry and methylation-specific PCR. The expression of E-cadherin was significantly higher in the well-differentiated oral SCCs than the moderately or poorly differentiated ones. None of eight tested benign pithelial hyperplasias showed aberrant methylation, whereas five of 12 oral squamous cell carcinomas showed aberrant methylation. When we compared E-cadherin expression with methylation status, oral SCCs with normal methylation showed a higher expression of E-cadherin than those with methylation. These findings suggest that aberrant CpG methylation of CDH1 promoter region is closely associated with transcriptional inactivation and might be involved in tumor progression of the oral mucosa.

명창 공대일의 삶과 예술세계

이명진(Lee Myung-Jin) 실천민속학회 2010 실천민속학연구 Vol.15 No.-

본 고는 해방 이후 판소리사에서 매우 중요한 역할을 담당한 명창 공대일을 조사ㆍ연구함으로써, 광주 지역에서 전승되던 소리의 일단을 밝혀 판소리사의 불충분한 부분을 보완하고 실증하고자 하였다. 전남은 서편제, 보성소리의 발원지이자, 수많은 명창을 배출한 곳이기도 하다. 특히 광주는 전남지역의 중심도시로써 판소리를 전승시키고, 공부하고, 또 이를 통해 생계를 유지하고자 많은 명창 및 소리꾼들이 모여들었던 판소리의 성지였다. 일제시대 예기양성소로 유명했던 광주권번은 판소리 교육의 중심이었으며, 해방 후에는 광주성악연구회, 호남국악학원, 전남민속예술학원 등 많은 단체들을 통해 판소리가 공연되고 향유되었다. 광주권번이 형성된 이후부터 1960년경까지 광주는 판소리의 지역 거검 역할을 하였다. 이 시기 공대일은 광주를 지역적 기반으로 하여 판소리의 전승과 교육을 담당한 인물로 주목된다. 그는 광주판소리의 최대 전성기에 광주에서 활동하며 많은 제자를 가르쳤고, 서울을 중심으로 명인ㆍ명창들이 활동을 하던 시기에도 계속 광주에 머물면서 판소리 교육에 힘썼다. 무대 활동 보다 후진 양성에 노력을 기울인 관계로 명성과 재물 등은 따르지 않았으나, 광주판소리 전성기라고 할 수 있는 시기에 다른 명창들보다 많은 제자들을 육성하고, 이를 통해 광주 판소리를 더욱 활성화 시켰다. 다시 말해 공대일은 광주 지역의 대표적인 국악학원에서 30여년 간을 활동하며, 광주판소리의 전승과 활로 역할을 담당했던 인물이라고 할 수 있다. 공대일은 광주라는 지역에 묻혀서 빛을 바래지 못했던 옥석이다. 그의 딸인 공옥진의 유명세에 힘을 얻어 광주라는 곳에 판소리 명창 공대일이 있었다는 존재감이 남게 되었지만, 그에 대한 연구는 잠깐의 언급 정도에 지나지 않는다. 그 때문에 출생, 탯자리, 활동까지 제대로 남아있는 자료가 없어 여러 가지 논란을 야기했고, 삶의 족적은 그와 함께 활동했던 그 지역의 예술인들에게 구술로써 전해들은 이야기를 재구성할 수밖에 상황이다. 그러나 필자는 이 글을 통해 공대일이 광주판소리를 논할 때 결코 빼놓을 수 없는 중요한 인물 중의 한명임을 확실하게 해두고 싶다. 광주판소리의 큰 줄기에는 孔家(공창식, 공대일, 공기남)의 힘이 자리 잡고 있기 때문이다. This essay is to research and study on Gong Dae Il who was playing the important role of Pansori in Kwangju Province after the restoration of independence from Japan. Now this research focuses to find. out what kinds of Pansori which is transmitted in Gwang Ju for helping the insufficient part of Pansori history. Jeollanam-do is a place which means the source of Seopyeonje and Boseong Sori and also turned out many Pansori artists. Especially, Kwangju was seem to be the holy centre of Paosori in Jeollanam-do and it has promoted the Pansori and most of people who worked at in this field came to Kwangju for their living hood during that time. Kangju-gwonbon is a famous place for producing the Yaegi who a female entertainer and also the centre of Paosori during Japanese colonial period. Since 1945, the Pansori was playing and enjoyed by Kwangju-Seongak Institute, Honarn-traditional music Institute and the other Institutes. During this time, Gong Dae Il was focused by his activities, transmitting and educating the Pansori in Kwangju area. He taught many students and was trying to promote the education of Pansori but the other expert of Pansoti conducted most of their time in Seoul. In the result of this, Gong Dae Il had lots of students compare with others but there was no money for him as a natural. It means that Gong Dae Il is now commented to play great role of promoting and making a route of Kwangju-Pansori for more than 30 years in his lifetime. Gong Dae Il was a important person in History of Pansori but most of his effort to promote the Pansori is not recognized by fair judgement, However, he is showed how much he meant to be to us by his daughter who is a famous Pansori artist, Gong Ok Jin. But it is not quite enough to explain his achievements and seems to briefly comment his works without his intensive research about him. For this reason, there are many issues about him such as birth, activity, because there are little data about him. This research focuses on Gong Dae Il was one of most important person who did great role of Pansori in Kwangju area and add the family of Gong(Gong Chang Sik, Gong Dae Il, Gong Gi Nam) in the centre of Kwangju-Pansori.
