Objectives : Pneumoconisis and noise-induced hearing loss (NIHL) have been reported as main occupational diseases by the Special Health Examination. The Industrial Accident Compensation Insurance has reported various work-related diseases, however, these two diseases occupied almost a half of compensated cases. Therefore, it was not well known about the status of occupational diseases other than pneumoconiosis, NIHL, and cardio-cerebrovascular accident (CVA). This study was conducted to analyze claimed cases as an occupational disease, that was requested to the Korea Industrial Safety and Health Agency (KOSHA). Methods : The local office of the Korea Labor Welfare Corporation (KLWC) has asked the KOSHA for confirmation of claimed cases as an occupational disease. We analyzed 379 cases requested from KLWC, the Ministry of Labor, employers, unions and occupational health agencies from 1992 to 1999. Results : Male was 80.7 % of the requested cases. Their mean age was 42 years old and 75.5 % of them were more than 35 years old. The requested cases were increased rapidly from 25 cases in 1992 to 108 cases in 1999 and the accept rate was 50.7 %. The majority of requested cases were respiratory diseases(22.4%), cancers(18.5%), Neuropsychiatric problems(14.5%), and musculoskeletal problems(13.5%). The accept rate was high in reproductive, respiratory, musculoskeletal and digestive disorders and low in neuropsychiatric, renal and otologic problems and occupational cancers. 73.6% of them were caused by chemical agents, especially 28.5 % were by organic solvents. 67% of them were clinically confirmed at university hospitals. A half of the cases were from KyongIn area, even the request came from the whole country. Conclusions : A claim was common in workers whose age was over 35 years old and exposure history was over 10 years. The respiratory diseases and neuropsychiatric disorders were still main problems in occupational health and occupational cancers was increasing even though its accept rate was not high yet.

DW-166HC (^(166)Holmium (^(166)Ho)-Chitosan complex) is a new radiopharmaceutic anticancer agent with a broad anti-tumorigenic spectrum, especially against human hepatic cancer. DW-166HC was evaluated for the appearance of micronucleus in polychromatic erythrocytes (PCEs) of mouse bone marrow cells after subcutaneous arid intravenous single administration. Bone marrow cells were prepared at 24 hr and 48 hr after DW-166HC-I (^(165)Ho-Chitosan complex : cold compound) administration and at 24 hr, 72 hr and 2 weeks after DW-166HC (^(166)Ho-Chitosan complex : hot compound) administration. The results showed there was no statistically significant increase of the numbers of PCEs with micronucleus in all DW-166HC-I administered groups compared with a negative control group but there was statistically significant increase of the numbers of PCEs with micronucleus at 24 hr arid 72 hr in all DW-166HC administered groups, which was recovered after 2 weeks from the drug administration. The results also showed the ratio of normochromatic erythrocytes (NCEs) to PCEs of all DW-166HC-I administered groups was not significantly different from that of a negative controi group but there was significant difference of this ratio at 24hr and 72 hr in all DW-166HC administered groups compared with that of negative group, which was also recovered after two weeks from the drug administration. These results suggested that DW-166HC-I may not cause any chromosomal damage but DW-166HC has in vivo mutagenic potential because of its radioactivity.

박규태,이상범,류근호 연세대학교 산업기술연구소 1985 논문집 Vol.17 No.1

Dataflow computers exhibit a high degree of parallelism which cannot be exploited in a conventional von-Neumann architecture framework. Among the well-established dataflow computers is an MIT machine, whose driving force is heavily based upon data-driven computation. This paper describes a new dataflow machine which further improves the relatively poor performance exhibited by the MIT machine. Our machine is designed by adding the notion of demand-driven computation to the MIT machine structure.

Suspended particles in the air were captured by high volume air sampler in the 29 sites of south Geyngsang area and measured total suspended particulate (TSP), heavy metals, and ion compounds. The results are following as; The average of TSP is 76.8㎍/㎥ throughout Gyeongnam area, and regional average is 124.9㎍/㎥ in industrial complex, 99.9㎍/㎥ road side area, and 52.9㎍/㎥ residential area. The highest level of TSP is 189.3㎍/㎥ in Yangsan industrial complex area. And the lowest is 34.1㎍/㎥ in Namhae residential area. The artificial contaminant(SO_4^2- and NO_3^-) have higher levels particularly road side area than industrial complex or residential area. Thus, it appears to be affected by emission gas of automobile. Fe is the heavy metal compound which of the highest concentration is 1.919㎍/㎥ in the air and Cd the lowest, 0.001㎍/㎥. In the regional aspect, it appesrs that industrial comples has high levels of Cl^-, Na^+, TSP, and heavry metals such as Zn, Pb and road side area has ion compounds such as SO_4^2-, NO_3^-. And there's no high level of concentration in residential area. The coefficient of correlation between Fe and Mn(P=0.000) is 0.999 in the industrial complex, that of Cr to Cd(P=0.003) is 0.997 in road side, and in the residential area that of Fe to Mn(P=0.000) is 0.867. Also, the correlation between Fe and Mn has totally the highest coefficient which is 0.995.

The study was carried out to examine how much clinically useful was the skin thickness in diagnosis of osteoporosis. The project was to look into not only the presumption that patients with osteoporosis have the skin loss at the similar rate of the reduction in the collagen content of the bone but also the correlation between the collagen content and the skin thickness. The skin thickness was measured on the dorsal hand(right) of the patients using an ultrasonic technique with a 20 MHz focused ultrasonic transducer. Measurements of the bone density of the patients were made on both the lumbar spine (L2-4) and the femoral neck using Dual­Energy X­ray Absorptionmeter(DEXA, Norland). An ultrasonic bone densitometer(Mark 6000, Medison Co. Korea) was taken to measure the speed of sound (SOS) on the calcaneus. It was observed that there were some degrees of correlation between the bone density obtained by the DEXA and the SOS of the calcaneous (P<0.01). There was no evidence that the skin thickness was correlated with the DEXA produced bone density and ultrasonically measured SOS.

박호근 숙명여자대학교숙명리더십개발원 2008 숙명리더십연구 Vol.7 No.-

본 논문은 동양고전 중의 하나인 『맹자(孟子)』에서 저자들이 강조하고 있는 지도자상은 무엇이며, 지도자의 자질에는 어떠한 것들이 있고, 그것이 주는 현대적 의미는 무엇인가를 탐색하는데 목적이 있다. 이를 위한 연구방법으로는 리더십에 관한 선행 연구를 기초로 『맹자』원전에 대하여 문헌 연구를 실시하였다. 연구내용은 맹자의 지도자상과 지도자의 자질(자기관리, 조직관리) 등 크게 두 가지로 나누어 고찰하였다. 연구결과 맹자의 지도자상은 곧 대장부이며, 지도자의 자질로써 자기관리는 자기성찰, 인내, 사표, 신용과 성실 등 네 가지의 자질을, 조직관리는 사람에 대한 판별력, 일의 우선순위, 인간존중과 타인에 대한 배려, 원만한 인간관계, 책임감 있는 보좌 등 다섯 가지의 자질을 고찰하였다. The purpose of this study was to investigate the leader's image and natures in the works of Mencius. Research method was literature-centered research which is mainly focused on the original works of Mencius. Study contents were investigated as two types. First, what is leader's image of Mencius. Second, what is the leader's natures in self management part and organization management part. Study results were as follow. First, leader's image of Mencius was "Deajangbu" who has a broad and vast mind, always stands on right point, and also does things 'rightly'. Second, as a self management part, self introspection, endurance, demonstration, credit and self sincerity were investigated. As an organization part, distinction power to the person, setting the priority order of work, human respect and consideration to other people, good human relationship, having a strong sense of responsibility to one's leader were investigated.

Syncope is not uncommon problem that needs broad differential diagnosis. Correct diagnosis of the cause of syncope is important, because although some causes of syncope such as vasodepressor syncope have benign prognosis, others such as ventricular tachycardia may need prompt diagnosis and treatment. We present a retrospective study of the patients with episodes of syncope brought to Emergency Medical Center of Chung Ang Gil Hospital from January 1994 to October 1994 and the results were as followings. 1. The patients with episodes of syncope accounte for 0.5% of total Emergency Department visits. 2. The male to female ratio was 4 : 6 and mean age was about 54-years old. 3. The cause of syncope was identifiable in 48% of the case and not in 52%. The noncardiac cause(56%) was more common than the cardiac(44%) and cardiac, noncardiac, SUO(Syncope of Unknown Origin) ratio was 1 : 1.4 : 2.6. 4. 29% of patients were dignosed by history taking, physical examination, and electrocardiography when they visited the Emergency Department initially, and 88% of patients with identifiable causes were diagnosed through initial Emergency Department investigation and Holter monitioring. 5. The rate of correct diagnosis can be increased if initial investigation includes Holter monitoring, and the further research for more accurate, inexpensive and noninvasive diagnostic method for syncope is needed.
