목적 : 본 연구는 마산, 창원, 거제에 있는 8개 사업장을 대상으로 사업장 응급의료의 현황을 조사하고 최근 4년간 발생한 25례의 사망재해를 분석하여 병 원전단계 응급의료체계의 실태와 문제점을 파악하고자 고안되 었다. 방 법 : 사업장 일반현황에 대한 조사와 사업장 응급의료체계의 실태를 조사하기 위하여 해당 사업장의 안전관리자 및 노동조합의 산업안전부서 담당자에 대한 면접조사를 시행하였으며 사망재해 발생 현황과 사망재해에 대응한 응급의료 실태 분석을 위하여 재해보고서, 사업장 내 의무실 기록, 응급센터의 의무기록을 조사하였다. 결 과 : 8개 사업장의 전체 노동자 수는 1999년 기준으로 26,803명 이었으며 각 사업장에는 작업공정에 특수한 위험 기기 및 공정, 위험 인화 및 폭발물질, 위험 고공 작업 공정이 있었다. 3개의 사업장에 상주 의사가 근무하고 있었으며 나머지 사업장에는 간호사 및 보건직 인력이 상주하고 있었다. 3개의 사업장에서 안전관련 교육을 연간 24시간 시행하였으나 나머지는 연간 8시간 이하의 교육을 시행하였다. 모든 사업장에는 의무실을 갖추고 있었으며 3개의 사업장은 구급차를 보유하고 있었다. 구급차의 동원에 필요한 시간은 6개 사업장에서 5∼10분, 2개 사업장에서 10∼30분이 소요된다고 하였다. 또한 응급센터로의 후송은 30분 이내에 모두 가능하였다. 그러나 모든 사업장이 기도유지 장비나 쇽 처치 장비는 보유하고 있지 않았다. 25례의 사망재해 중 1개 사업장에서 15례가 발생하였으며 4개의 사업장에서는 사망재해가 발생하지 않았다. 사망재해의 경력별 분포에서 10년 이상인 경우가 64 %에 달하였고 68 %의 사례는 낙하, 충돌, 추락 등 재래형 사망재해 유형에 해당하였다. 사망재해시 1차 구조는 대부분 사내외 소방서에 의뢰하였으며 구급차의 동원은 87 %가 10분 이상을 소요하였다. 사망재해 중 48 %에서는 현장내 응급 처치가 전혀 시행되지 않았으며 응급센터로의 후송 시간 역시 50 %에서 30분 이상을 필요로 하였다. 사망시간은 재해 이후 1시간 이내가 40 %, 1∼4시간이 50 %를 차지하였으며 사망원인에서는 68 %가 두경부 및 흥부 손상에 의한 사망이었다. 결 론 : 본 연구를 통하여 파악된 사업장 응급의료 체계의 문제점은 첫째 일반노동자에 대한 재해관련 교육의 부족 둘째, 응급의료 인력에 대한 지식 및 기술의 부족, 전문인력의 상주 및 배치의 부족 셋째, 중증재해에 대비할 수 있는 응급의료 장비의 부족 넷째, 응급센터로의 신속한 후송에 필요한 인적 물적 자원의 부족 등이다. 이를 바탕으로 사업장에 특 이적인 병 원전단계 응급의료체계의 구축을 위하여 보다 세부적인 연구가 필요하다고 사료된다. Objectives : This study was designed to evaluate the problems of pre-hospital Emergency medical care system (EMS) in workplace. We analysed 25 fatal work-place injuries during the recent 4 years and the work-place EMS of 8 enterprises located in Masan-city, Changwon-city and Kuje-island. Methods : The safety managers and the members of Dept. of safety in the labor unions were interviewed about the work-place EMS. And we investigated on the injury reports, the work-place medical-room records and the medical records of emergency center for fatal 25 cases. Results : The enterprises had the at-risk machines and processes, volatile materials and high-altitude working processes. There were duty doctors in only 3 enterprises but a few duty nurses or health-care providers in the others. The time spent for the education to the workers on safety was 24hrs/yr in 3 enterprises in 1998 but less than Bhrs in the others. There were medical service center in all enterprises but the ambulances in three. The time for activation of the ambulance was ranging from 5 minutes to 10 minutes in 6 enterprises, and from 10 minutes to 30 minutes in two. The patient transportation to the emergency center was possible within 30 minutes in all enterprises but there were no equipments for airway maintenance and shock management in all enterprises. The 15 (60%) fatal injuries were occurred at one enterprise. The 64% of casualties had the duration of job-employment more than 10yrs and the 68% were suffered the typical type of work-place injury as descending injuries, collisions and falls. Most of all primary calls for rescue were concentrated on the fire-service agencies. But in 85% of fatal injtories, the tome for the activation of ambulance was more than 10 minutes and no emergency care was taken in the field in 48 percent of casualtles. The transportation time to the emergency center was more than 30 minutes in 50 percent. It toolk from injury to death was less than one hour in the 40 percent of all cases, and from one hour to four in the 50 percent. The causes of death in the 68 percent were the head-and-neck injuries or thoracic injuries. Conclusions : We found that there was Insufficiency of the education associated with work-place injury for workers, manpower and facilities, equipments related to the work-place EMS, the problems of the delay in transportation system.

본 고에서는 재무변수와 경제변수에 의한 한국과 영국, 미국의 전체 주식시장 수익률 예측력을 조사하고 이들 국가들의 자본시장 동조화 현상에 대하여 연구하였다. 단기 금리는 전체 주식시장 수익률을 예측하는 데 중요한 역할을 한다. 배당수익률은 미국과 영국의 주식시장 수익률과 어느 정도 예측력을 가진다. 이익수익률은 세 시장 모두에서 거의 설명력이 없다. 그렇지만 단기 금리만으로는 세 국가 모두에서 주식 수익률을 예측하기 어렵다. 단기 금리와 배당수익률을 동시에 고려할 때 예측력이 가장 높아진다. 그러나 이들 회귀식의 설명력들은 설명력이 매우 낮아서 효율적 시장가설을 기각하는 증거로 받아들이기 어렵다. 한편 미국 관련 변수들은 한국과 영국의 주식수익률예측에 도움이 된다. 영국 관련 변수 역시 미국 시장수익률 예측에 도움이 된다. 이들 시장은 단기적으로 통합되어있지 않으며 특히 한국 시장은 영국과 미국시장과 단기적으로 독립적이다. 그렇지만 전반적으로 이들 3개국 사이에는 오차수정에 의한 장기 균형 관계가 존재하며 기대수익률에 공통된 움직임이 있다는 증거가 있어서 장기적으로 동조화되어 있음을 알 수 있다. 이러한 관계는 표본기간의 후반기인 2000년대에 더욱 두드러지게 나타나서 시장의 균형을 향상 조정속도가 빨라지고 있다

The ice cream, a type of freezing food of condensed state of milk, richer in nutritions and easily available in all seasons, is one of luxuary items. The fatty acids in the milk is the most important component of ice cream which not only improve the nutritional value but also is easier digestive, more rapidly absorbed than those of plant and also has influence up the quality of the goods. In order to see the fatty acid distribution of the fats in the ice cream on the market, the ice creams on the market were selected in accordance with things most in demands of each manufacture divided into the shape. and analyzed for the concentration of total lipid, acid value, iodine value and saponification value. For the compositional analysis of fatty acid of milk as basis and those gas liquid chromatography was also used. The following were the results obtained. 1) The average total lipids in milk and, the 3 kind of ice creams shaped carton, cone and bar were 3.04, 8.34, 6.41, and 5.4% respectively. 2) The average acid values of milk and each of 3-different type of ice creams shaped carton, cone and bar were 0.72, 0.62, 0.76, and 0.95 respectively. 3) The soponification values. Ranged from 180 to 260, varied great degree depending upon. the different manufactures, the average saponification value of the milk and each type of ice cream shaped carton, cone and bar were 208, 226, 226 and 215 respectively. 4) The iodine values varying great degree upon the different manufactures ranged from 10 to 32, the average values of milk and each type of ice cream shaped carton, cone and bar were 29, 20, 19 and 22 respectively. 5) The fatty acids analyzed for milk and ice cream, were 17-different kind, for the milk palmitic acid appeared principal constituents which valued 29.8%, whereas oleic acid were 27.1%. Since the compositions of fatty acid in ice creams for each different manufacture varied so great degree from manufacture to manufacture that the average values of those for the same shaped ice creams seems to have no meaning, if the compositions of fatty acid in the ice cream were considered according to the manufactures such as A, B, C, D and E companies. 27.4% lauric acid which was principal constituents, 17.8% palmitic acid and 11.8% oleic acid which was equal to 1/2 of that in the milk were found in the product of A company, 28.2% oleic acid and 27.8% palmitic acid which had similar pattern with the composition as that of milk in the product of B company, 25.5% palmitic acid, 22.7% oleic acid and 11.6% lauric acid in the product of C company, 34.4% lauric acid, 15.6% palmitic acid and 8.6% oleic acid which amounts to 1/3 of that in the milk in the product of D company, and 24.6% lauric acid and 18% palmitatic acid in the product of E company respectively. For the ratio of saturated to unsaturated fatty acid, these were 84 : 16 in the product of At 62 : 38 in the product of B, 68 : 32 in the product of C, 88 : 12 in the product of D, 79 : 21 in the product of E respectively, while this ratio for milk was 63 : 37. Although the compositional characteristic of fatty acids in the ice creams varied great degree according to the manufactures, all kinds of different shaped product showed the same pattern in composition regardless of the type of ice cream shaped in provided they were made in the same company. The lauric acid was more exuberant, however oleic acid, unsaturated fatty acid, was of less quantity than in the milk fat. In general, there was less quantity of unsaturated fatty acid in the ice creams compared with in milk.

PCDD/F(Polychlirinated dibenzo-p-dioxins and dibenzofurans) in both of treated fabric and untreated fabric for working clothes of a municipal waste incineration were determinated. The treated fabric for working clothes was developed for less exposure of PCDD/F in municipal waste incinerations. The total concentrations of PCDD/F in some parts such as surface, middle layer, inside for treated and untreated fabric were investigated. The I-TEQ value of surface was 0.23370ng ·TEQ/g for treated fabric, 0.15355ng ·TEQ/g for non-treated fabric. On the other hand, the value of middle layer was 0.00077ng ·TEQ/g, 0.00177ng ·TEQ/g, respectively. The surface of the treated fabric containing high levels PCDD/F was caused by absorption of them. Therefore, PCDD/F of the treated fabric in middle layer was less I-TEQ value than that of the untreated fabric. The treated fabric makes effect on preventing PCDD/F from permeating into human body.
