Background: The initial history, physical examination, and ECG assessment should focus on identification of potentially serious noncardiac or cardiac disorders, including coronary artery disease, congestive heart failure, and electrical instability at the emergency room. additionally, it is essential to define disease severity, stability and need for emergency therapy. echocardiography is a useful tool for this purpose. especially Doppler echocardiography may be more sensitive and time-saving diagnostic tool for the evaluation of patients presenting with cardiogenic symptoms. So we evaluate the feasibility of the echocardiographic measurement by emergency physicain after short-term course. Method and Results: Twenty volunteers(10 male, 38.8±9.3 years) were included in the study for measurement of myocardial performance index and established parameters of ventricular function using conventional echo-Doppler methods. Myocardial performance index: (ICT+IRT)/ET, was obtained by subtracting ejection time(ET) from the interval between cessation and onset of the mitral inflow velocity to give the sum of isovolumic contraction time(ICT) and isovolumic relaxation time(IRT). The most of mean values of echocardiogrphic parameters were not significantly different between those of cardiologist and those of emergency physicians(p<0.01). The duration for measuring myocardial performance index was shortest among echocardiographic parameters. the validity of echocardiographic parameters measured by emergency physicians was proved relatively good. Conclusion: It is proved to be feasible for emergency physician to perform echocardiographic evaluation of ventricular function after short-term course

박탈과 증오의 바람 : 이만희 감독의 <휴일>(1968)을 중심으로

김만석(Kim, Man-Seok),김필남(Kim, Feel-Nam) 한국문학회 2021 韓國文學論叢 Vol.88 No.-

본고는 이만희 감독의 영화 <휴일>을 당대 사회의 반영이나 재현이 아니라, 정동(affect)의 차원에서 분석함으로써 영화가 이데올로기나 선전도구가 아니라 자율적인 영역을 구축했다는 점을 주장한다. 달리 말해 <휴일>은 서사 중심의 영화가 아니라, 인물들의 관계에서 발생하는 힘에 주목하며, 어디로 나아갈지 모르는 카메라의 힘이 운동하는 방향에 주목하고 있는 독특한 구조로 흘러가는 영화임을 분석하고 있다. 먼저 영화는 ‘휴일’이라는 시간을 출발점으로 삼고 있지만 쉼이나 휴식이 아니라 자본주의 체제의 지속을 위한 재생산(reproduction)의 시간임을 인물들 간의 관계를 통해 보여준다. 주인공 ‘허욱’과 ‘지연’은 가난한 연인으로 커피 한 잔 사먹을 돈이 없어 공원에서 데이트를 하고, 아이를 키울 형편이 안 돼 낙태 비용을 마련하기 위해 모욕적인 상황을 마다하지 않는다. 허욱이 낙태 비용을 마련하기 위해 친구들을 만날수록 걷잡을 수 없는 한계 상황으로 내몰리는 것을 확인할 수 있다. 허욱의 친구들 또한 심심해서 처음 만난 여자와 섹스를 하거나, 술에 취해 있거나, 목욕을 여섯 번이나 하는 등 무기력하게 시간을 보내는 인물들로 그려진다. 그런 점에서 이 영화는 ‘휴일’이라는 시간이 진정한 휴식이 아니라 재생산을 위한 시간이며, 생산활동을 하지 않는 인물들은 극한의 상황에 내몰리고 있음을 확인할 수 있다. 허욱은 휴일이 끝나갈수록 더 무기력해지고, 결국 혐오의 시선으로 자신을 바라보던 친구 ‘규제’로 인해 자기 파괴적인 증오의 감정을 표출하기에 이른다. 즉 영화는 허욱을 통해 휴일이라는 시간이 생산활동과 재생산의 세계를 파악하게 만든다. 마지막으로 본고는 사회적 불안정성이 증대되고 변동이 극심화 되어가는 1960년대 후반 기존에 자신이 누리던 지위나 위치를 상실할 경우 사회적으로 취약한 계급이나 계층은 무기력이나 증오의 감정에 더욱 취약할 수밖에 없음을 영화 속 관계들을 통해 분석하고 있다. In this paper, the movie, <A Day Off> directed by Lee Man-hee, was analyzed not as the reflection or reproduction of the society of those times, but at the level of stillness and movements, and it was argued that the film had established an autonomous area rather than had been used as the means of ideology or propaganda. In other words, it was analyzed that <A Day Off> was not a narrative- centered movie, but one focusing on the power generated in the relationships among the characters, and had a unique structure of paying attention to the direction of the camera s dynamic without knowing where it would head. First, the film begins with the time of ‘a day off’, yet it s revealed through the relationships among the characters that it is not rest or break, but the time of regeneration for the continuance of the capitalistic system. The main characters in the movie, ‘Heo Wuk’ and ‘Jiyeon’ are poor lovers, who have a date in the park because they don t have money for a cup of coffee and don t say no to insulting situations when they have to raise money for abortion because they can t afford to raise a child. We can see that the more Heo Wuk meets his friends to prepare to pay for abortion, the more he becomes forced into an uncontrollable critical situation. Heo Wuk s friends are also described as the figures spending time spiritlessly, having intercourse with a woman whom one meets for the first time because he is bored, being drunken, or taking a bath six times a day. In that sense, it can be proven that in this movie, ‘a day off’, doesn t mean true rest, but is just time for reproduction, and those not engaged in production activities are being driven into extreme situations. As the day off is drawing to its close, he becomes lethargic more and more, and ends up expressing the emotion of self-destructive hatred because of his friend, ‘Gyu-je’, who sees him with the eyes of disgust. That is to say, the film makes one figure out the time of a day off showing the world of production activities and reproduction through Heo Wuk. Lastly, in this paper, it was analyzed through the relationships in the movie that in the latter half of 1960s when social instability was increasing and changes were becoming severe, when one lost the position or status that one used to enjoy, the one belonging to the weaker class or rank in the society couldn t help but become more vulnerable to the emotions of lethargy or hatred and disgust.

The purpose of this study was to perform a kinematic analysis of the high jump techniques of the three men`s medalists at the 2011 IAAF Championships in Daegu (August 27-September 4, 2011), In particular, a three-dimensional coordinates method was used to analyze the last three strides before touchdown, the touchdown techniques, and the movements after takeoff toward the bar. An analysis of the, data for the biomechanical characteristics of the world`s best high jumpers could contribute to an improvement in the performance of a national high jumper. The first conclusion of the data analysis was that the arm movements of the gold medalist, J. Williams, had a single arm form, whereas the arm movements of the other medalists were a double arm form. Second, the difference in the knee joint angles upon touchdown and toe-off was 10˚. Third, J. Williams achieved his maximum CM height after takeoff (1.26m) using the maximum flexion of his knee joint. Fourth, the foot contact duration of A. Dmitrik (0.11 s) was the shortest among the medalists, and the ratio for his transformation of horizontal velocity to vertical velocity was the greatest (75.25%) among the three. Last, the maximum CM height of T. Barry was the greatest, and his foot contact duration was the longest.

The heat performance in a forced circulating cool storage room was numerically investigated. A commercial PHOENICS package was used to simulate 3-D airflow. For solving the governing equations a standard k-ε turbulent model was implemented to calculate steady state turbulent velocity and temperature distributions. The results show that the large air contacting area of products increases the storage quality, because the airflow between products helps to remove the heat from the products by convective heat transfer.

During a long journey of agricultural products from the production area to markets, the quality of agricultural products was always affected by some degree of vibration. The vibration input during the transportation may cause serious agricultural product injury, and this damage is particularly severe whenever the vegetable inside package is free to bounce, and is vibrated at its resonant frequency. The objectives of this study were to determine the resonant frequency of the oriental melon and to investigate the relationships between resonant frequency and physical properties of the oriental melon such as mass, volume and major and minor axes. In this study vibration testing device was constructed to determine the vibration response of the oriental melon in frequency ranges of 5 to 150 Hz. The computer program for controlling the vibration shaker and the function generator and measuring the vibration characteristics of the oriental melon was developed. The ranges of resonant frequency and peak acceleration at resonance of the oriental melon were 51 to 73 Hz and 1.24 to 1.92 G-rms, respectively. The resonant frequency and the peak acceleration decreased with the increase of the sample mass, volume, major and minor axes of the oriental melon. Multiple regression models for resonant frequency and peak acceleration of the oriental melon as a function of mass, major axis and minor axis of the sample were developed and analyzed.
