목적: ^(99m)Tc-lactosylated serum albumin (^(99m)Tc-LSA)은 간세포에 특이적으로 결합하는 간수용체 영상용 방사성의약품으로 새로이 합성되었다. 간섬유화를 유발하는 dimethylnitrosamine (DMN)을 투여한 간 손상 휜쥐 모델에서 ^(99m)Tc-LSa의 역동학적인 간섭취를 조사하고 간효소치의 변화와 조직학적 소견을 비교하여, LSA의 간섭취가 간기능의 변화를 반영하는지를 연구하였다. 대상 및 방법: SD계 흰쥐에 DMN를 27 mg/kg으로 복강 내 주사하여 급성 간손상을 유도하고 대조군과 비교하였다. DMN을 주사한 흰쥐를 3일(DMN-3), 8일(DMN-8), 21일(DMN-21)에 ^(99m)Tc=LSA (1,665 mg/kg) 29 MBq를 정맥 주사하여, 30분 동안 동적 영상을 획득하고 간과 신장부위에 관심영역을 설정하여 간과 심장부위의 시간방사능 곡선을 얻었다. 간기능 평가를 위해 시간방사능 곡선을 이용하여 간섭취지수와 혈중제거지수를 구하였고 곡선 최적화를 시행하였다. DMN 투여군과 대조군의 간효소치의 변화와 간조직의 광학현미경 소견을 비교하였다. 결과: 대조군에서는 ^(99m)Tc-LSA가 빠르게 간에 섭취되고 혈중에서 제거되었으나 DMN을 처리한 군에서는 간섭취가 낮았다. 간섭취지수의 비교에서 대조군에 비해 DMN 처리군에서 유의하게 간섭취지수가 낮았다(DMN-3: 0.842, DMN-8: 0.898, DMN-21: 0.91, 대조군: 0.96, p<0.05). 혈중제거지수의 비교에서도 대조군에 비해 DMN 처리군에서 혈중제거지수가 유의하게 높았다(DMN-3: 0.731, DMN-8: 0.654, DMN-21: 0.604, 대조군: 0.473, p<0.05). 비선형 회귀분석에서 R_(2) 값은 0.9이상으로 좋은 일치를 보였고, 대조군에ㅓ K값이 DMN처리군에 비해 크고(DMN-3: 0.28, DMN-8: 0.41, DMN-21: 0.46, 대조군: 0.97, p<0.05), T_(1/2)값은 작았다(DMN-3: 2.5, DMN-8: 1.7, DMN-21: 1.5, 대조군: 0.7, p<0.05). 간효소치의 변화는 DMN-3군에서는 대조군에 비해 상승하였으나 DMN-8, DMN-21군에서는 간효소치의 상승이 관찰되지 않았다. 간조직 소견의 경우 DMN-3군에서 중심정맥 주위에 괴사가 관찰되었으나 DMN-8군, DMN-21군에서는 미약한 정도의 염증세포 침윤만이 관찰되었다. 결론: ^(99m)Tc-LSA 간신티그래피의 간섭취 정도는 간손상과 반비례하였으며 간섭취의 변화는 조직학적 손상이 심한 정도와 간손상후 회복되는 과정을 반영하여 주었다. ^(99m)Tc-LSA 간신티그래피가 간손상을 평가하고 간손상후 회복되는 과정을 추적하는 간수용체 영상용 방사성 의약품으로 사용될 수 있을 것으로 생각된다. Objects: ^(99m)Tc-lactosylated human serum albumin(LSA) is a newly synthesized radiopharmaceutical that binds to asialoglycoprotein receptors, which are specifically presented on the hepatocyte membrane. Hepatic uptake and blood clearance of LSA were evaluated in rat with acute hepatic injury induced by dimethylnitrosamine(DMN) and results were compared with corresponding findings of liver enzyme profile and these of histologic changes. Materials and Methods: DMN (27 mg/kg) was injected intraperitoneally in Sprague-Dawley rat to induce acute hepatic injury. At 3(DMN-3), 8(DMN-8), and 21(DMN-21) days after injection of DMN, LSA injected intravenously, and dynamic images of the liver and heart were recorded for 30 minutes. Time-activity curves of the heart and liver were generated from regions of interest drawn over liver and heart area. Degree of hepatic uptake and blood clearance of LSA were evaluated with visual interpretation and semiquantitative analysis using parameters (receptor index : LHL3 and index of blood clearance : HH3), analysis of time-activity curve was also performed with curve fitting using Prism program. Results: Visual assessment of LSA images revealed decreased hepatic uptake in DMN treated rat, compared to control group. In semiquantitative analysis, LHL3 was significantly lower in DMN treated rat group than control rat group (DMN-3:0.842, DMN-8: 0.898, DMN-21: 0.91, Control: 0.96, p<0.05), whereas HH3 was significantly higher than control rat group (DMN-3: 0.731, DMN-8: 0.654, DMN-21: 0.604, Control: 0.473, p<0.05). AST and ALT were significantly higher in DMN-3 group than those of control group. Centrilobular necrosis and infiltration of inflammatory cells were most prominent in DMN-3 group, and were decreased over time. Conclusion: The degree of hepatic uptake of LSA was inversely correlated with liver transaminase and degree of histologic liver injury in rat with acute hepatic injury.

Gui-Sun Moon, Sun-Woong Kim, Jeong-Ah Shin, Hae-Kyung Wee, Jong Un Park, Myung-Kwan Park, and Wonil Chung. 2018. Voice Mismatch Meets Neurolinguistics. Studies in Modern Grammar 99, 85-115. This paper aims to investigate Korean advanced L2 English learners’ strategies for ellipsis resolution during sentence processing. Ellipsis resolution is known to involve several stages of information processing from the initial step of detecting an ellipsis-licensing element by the parser to the final stage of integrating the ellipsis site with the information retrieved from the antecedent of the ellipsis site. In examining these steps, we have manipulated three factors: (i) TP vs. VP-ellipsis; (ii) two types of discourse coherence relations (resemblance(-contrast) vs. cause-effect relations); (iii) voice match vs. mismatch. We found through the ERP recordings that voice mismatch in TP ellipsis elicited N400, followed by P600, irrespective of discourse coherence relations. In contrast, voice mismatch in VP-ellipsis registered N400 only in resemblance(-contrast) relation, but not in cause-effect relation. These findings lead us to conclude that Korean advanced L2 learners of English seem to undergo the full sequence of processing stages required for ellipsis resolution.

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.

This study is deep sematical investigation about tie kinds & the shapes of the ornaments for men used in the end of Chosun (about from 1700 to 1850) through the genre pictures and the other pictures kept in national museum From this study. we can get the esthetic sense and esthetic symbol of the people those who lived in that time. Wearing ornaments for everyday life was not governed by nation power but by social customs. And these can be divided by these kinds of series, i. e., Libja, Keon, Sushik, Libshik, Dae and Hae, etc. Ⅰ am dealing its shapes, materials, way of use in Section Ⅲ. Section Ⅳ is a symbolic investigation for those ornaments in which we can see the times, the culture, the customs and the way of thinking. Most of ornaments used in the end of Chosun didn't aim purely to decorate, instead, the people of that times added some kinds of decoration sense to the object having practical and functional propensity and through this procedure, they got the esthetical satisfaction. As its example, there is Libja, Keon and Dushik..Libshik (Mangkeon, Tangkeon, Donggot, Pungiam, Kwanja, etc). In these kinds of decoration for head. its shapes and wearing figures formed everyday life style of those days and showed us their Confucian totalitarian mind. As the Confucian ideas came to be whole social basic thinking, the shapes, the kinds, and the print of ornaments discriminated between upper and lower class. In addition to that, because that period was consisted of each social class, it occurred variously that a phenomenon of using high-quality and expensive raw materials for higher class. There were Hoeja and Kwanja which divided the materials up to 'Pum' class, and also were Pungjam and Ibyoung which indicated the level of class with the way of use in raw materials. Therefore, through these ornaments, we can see the fact that these kinds of ornaments played the symbolic role that showed and indicated the promotion in class 'Sunbi, scholar', In the end of Chosun, lower class who made big fortune by doing practical science, started to mimick the upper class ornaments. So, upper class, in order to defend this kind of propensity and to differenciate from lower class, started to effort to have and keep their own ornaments. Those efforts were resulted in the various kinds of shapes of ornaments. Its representative example is the change of the shapes in 'Kat'. Through the shapes and the print of the ornaments which had symbolic meaning, i.e. 'Ui, a symbolic thing or meaning earned by experience', 'Sadaebu, the man of noble birth' wanted to show symbolically their mental desire of hope. In the shape of Kwanja or at the edge of Heuklib and in the print of some part of Yangtae, etc. we can see these ornaments having 'Ui'.

Objective: This study was carried out to investigate if the measurement of range of motion(ROM) could be applied in the diagnosis of Myofascial Pain Syndrome(MPS) and to determine the severity by analyzing ROM in MPS patients. Methods: The study subjects were 476 female telephone number information service workers. Southampton Protocol and Pittsburgh Protocol were used to diagnose MPS and to measure ROM. ROMs were measured by 2 inclinometers exercising each shoulder passively and actively in 5 directions ; abduction, forward flexion, extension, external rotation, and internal rotation. Results: Compared to the normal group (n=147), the mean of right side ROM in the subjects (n=270) with same side MPS was 2.1˚ (SD=11.5) lesser in active extension and 1.7˚ (SD=10.4) lesser in passive extension. Compared to the mild group (n=210), the mean of right side ROM in the patients with same side severe MPS (N=58) was lesser in all directions. Especially in active forward flexion, passive forward flexion, active extension, passive extension and active external rotation, ROM in the subjects with severe MPS was lesser by 6.5˚ (SD=13.1), 5.1˚ (SD=12.8), 5.9˚ (SD=11.8), 5.0˚ (SD=10.6) and 3.9˚ (SD=9.8), respectively, than those of the subjects with mild MPS. Compared to the subjects with left side mild MPS(n=172), ROM in the subjects with left side severe MPS (n=59) was 5.3˚ (SD=13.3) lesser in active forward flexion. Conclusions: In this study, ROMs in the subjects with severe MPS tended to be lesser than those in mild patients. This tendency was more prominent in the right side than the left, active range of motion than passive and forward flexion and extension than others. The results of this study are expected to help diagnose shoulder MPS and determine severity.
