        김운,김익수,최세진 충남대학교 의과대학 지역사회의학연구소 1977 충남의대잡지 Vol.4 No.2

        To evaluate the specificity and the historical trends of the anesthetic agents and anesthetic methods used in Chungnam National University Hospital, anesthetic experiences of 8686 in total performed at Chungnam National University Hospital from January 1967 to December 1976 were analyzed statistically and clinically according to their age, sex, surgical department, physical status, premedicants, anesthetic agents and anesthetic methods. The results were as follws: 1. The number of the surgical patients has been increased yearly since 1972. (At that time, the Chungnam medical center was changed into Chungnam national university hospital.) 2. The age was in the range from the second to fourth decade in more than 2/3 of the total cases. 3. The number of the male patients 4,583 cases(52.8%) was more than that of the female patients 4,103(47.2%). 4. The frequency of the operations was in that order as follows: General surgery 3,610 cases(41.6%), OB&GY 1,914 cases(22.0%), orthopedic surgery 1,907 cases(21.9%), E.N.T. 729 cases(8.4%). 5. Emergency operation 2,841 cases(32.7%) was 1/3 of the total cases. 6. According to the classification of American Society of Anesthegiologists most of the cases belonged to the class 1, 2,542 eases(28.2%), cases 2, 2,965 cases(34.1%) and class1-2E, 2,354 cases(27.1%). Almost of all the cases were relatively in good physical status. 7. As premedicants, atropine and demerol, 6,027 cases(69.3%) had been used most frequently. But its use decreased recently because the use of the valium 624 cases(6.49%) instead of them has been increased. 8. Thiopental sodium 6,262 cases(75.6%), epontol 1,294 cases(15.6%) and ketamine 117 cases(1.4%) had been used as intravenous induction agents. 9. Ether 4,671 cases(56.4%) had been used mainly as anesthetic agents before 1972. But after the years of 1972, the use of halothane had been increased yearly. 10. The general anesthesia 8,287 cases (95.4%) had been employed in most cases. But recently it shows that the intravenous anesthesia has been increased. 11. The circle absorption system 7,848 cases(94.7%) had been employed in most of the inhalation anesthesia. But it shows that the frequency of the nonrebreathing system has been increased for pediatric anesthesia recently.

        金雲瑞 서울大學校 保健大學院 1974 公衆保健雜誌 Vol.11 No.2

        From March 1 to 31, 1974, surveys were conducted on the employment status of school nurses at 559 primary, middle and high schools in Seoul. The results of surveys are summarized as follows: 1. Questionnaires were stint to a total of 559 primary, middle and high schools in Seoul. Respondent school nurses numbered 210 showing a response rate of 37.4 percent. 2. The age group of 20 to 29 years constituted 46.7 percent of the 210 respondent school nurses, a proportion greater than that of any other age group. Those at the age of 40 years or more occupied only 11.4 percent, particularly at primary schools, the age group of 30 to 39 years constituted a great proportion while the age group of 20 to 29 years was a great proportion at middle and high schools. Their average age was 36.7 years for the primary school, 28.2 years for the middle school and 22.1 years for the high school. 3. Natives of Seoul constituted 56.2 percent, the greatest proportion, broken down into 43.4 percent for the primary school, 59.5 percent for the middle school, and 63.2 percent for the high school. 4. Whether they live together with their family is one of the factors determining the stability of their employment. Only 116 school nurses or 55.2 percent of the respondent nurses lived with their family while the others, 44.8 percent, lived separately from their family. 5. In mast cases, the number of family members of school nurse was five or six, in as much as 26.7 percent accounted for five family members and 32.4 percent for six family members. 6. As for the marital status of school nurses, 71. 4 percent was married and 27.6 percent unmarried. Thus, approximately two-thirds of them were married. 7. By education for which they acquired license, they were broken down into 20 percent for graduates of nursing school 56.2 percent for graduates of four-year nursing college or nursing department of university. At primary schools, 56.6 percent accounted for graduates of nursing high school, and at middle schools, the same accounted for graduates of four-year nursing college or nursing department of university. 8. Most of the school nurses acquired their licenses in or after 1960. In case of Primary schools, the greatest group or 53.3 percent obtained nurse's licenses from 1960 to 1964. At middle and high schools, those who acquired license from 1970 to 1974 constituted the largest proportions, 67.6 percent and 53.3 percent respectively. 9. The number of classes assigned per school nurse reached 90 or more at two primary schools, and 20 to 29 at most of the middle and high schools. 10. The number of student assigned per school nurse was 5,000 or more at 33.3 percent of primary schools. 2,300 to 3,000 at 64.9 percent of middle schools. and 1,000 to 2,000 at 47.4 percent of high schools. 11. As for the length of service of school nurses, the greatest proportion was constituted by those with one or two years of clinical experience, and the second greatest proportion by those with one or two years of experience in their current positions. In terms of the total length of employment, however, the school nurses of primary school showed a longer average period of employment than that of school nurses at other schools. The second longest was for the middle school, and the third for high school. 12. As a whole, 96.2 percent of the school nurses was licensed and 3.8 percent unlicensed. 13. Of the school nurses of primary school, 93.2 percent had received training. Corresponding figures were 21.6 percent for middle schools, and 34.2 percent for high schools. These data indicate that school nurses of primary school had received more training than their counterparts of middle and high schools had. 14. Time those wishing to continue to work as school nurse for first or more years in the future constituted 56.7 percent of school nurses of primary school. That was far higher a ratio as compared with its corresponding figures 16.2 percent for middle school and 23.7 percent for high school. Those wishing to continue to work for lifts occupied 13.4 percent at primary schools. 15. As for desired place of work, 46.6 percent was content with their current positions at primary schools, but corresponding ratios were lower at 16.2 percent for middle schools and 18.4 percent for high school s. 16. At primary schools, the greatest proportion or 40 percent was paid monthly salaries of 40,000 to 50,000 won. At middle and high schools, the greatest proportions, respectively 62.2 percent and 60.5 percent, received 50,000 to 60,000 won.

        온라인 플랫폼을 이용한 광고 아이데이션 회의 성과에 관한 탐색적 연구 : 대학생 집단을 중심으로

        김운한(Kim, Woon-Han) 한국광고홍보학회 2021 한국광고홍보학보 Vol.23 No.4

        본 연구의 목적은 온라인 플랫폼을 이용한 광고 아이디어 회의 과정에서 지각된 참여 및 회의성과를 높이는 요인들의 역할을 탐색하는 것이다. 연구 목적을 위해 팀 상호작용에 따른 과제유형 특성과 사안의 긴급성, 개인의 창의적 자아효능감 및 온라인 플랫폼에 대한 태도 변수를 사용하여 온라인 회의 참여도 및 지각된 회의성과가 달라지는지를 알아보았다. 대학생 집단을 대상으로 한 실험 결과는 다음과 같다. 첫째, 창의적 자아효능감이 낮은 집단은 높은 집단에 비해 개인과제에서 지각된 참여가 상대적으로 더 낮았으며, 집단 과제에서는 자아효능감이 높은 집단과 낮은 집단 간 지각된 참여 차이가 적었다. 둘째, 과제유형과 온라인 회의플랫폼에 대한 사전태도에 따른 지각된 참여는 상호작용성이 높은 집단과제와 사전태도가 높은 집단에서 더 높았다. 셋째, 긴급성이 큰 사안의 경우, 회의 인원이 적을 때 지각된 온라인 회의 성과가 더 긍정적이었으나, 긴급성이 적은 사안에서는 회의 인원에 따른 지각된 회의 성과 차이가 없었다. 넷째, 사안의 긴급성에 따른 동조 차이는 회의 집단 규모에 따라 제한적으로 유의하게 나타났다. 동조는 대규모 회의에서 긴급 사안일 경우에 상대적으로 크게 나타났다. 연구결과를 바탕으로 온라인 상황에서 광고 아이데이션 회의 성과를 높이기 위한 몇 가지 방안을 제시하였다. This study aims to explore the performance factors of online advertising idea(Ideation) meetings and college students’ perception of meeting efficiency. For the purpose of the study, two experimental studies are conducted. The results are as follows. First, individual creative self-efficacy and task type showed significant interaction effects on perceived participation in online meetings. Second, perceived participation was higher in the group task with high interactivity, and the perceived participation of the group was higher with high attitude toward the online platform. Third, the preference for online meetings was greater when the number of meetings was small with tasks with high work urgency. Fourth, the degree of conformity showed marginal significant differences according to the group size and the urgency of work. Based on the results, some practical implications are suggested to increase the outcome of the advertising idea meetings both for education and business fields.
