The management of twenty-two children with blunt abdominal trauma was analyzed. Nineteen cases had intraabdominal injuries; involving the spleen in 7 cases, the liver in 5, the pancreas in one and the bladder in one. There were five case multiple intraabdominal organ injuries. Seventeen out of 19 patients were treated non-operatively, but one was operated upon later because of delayed bleeding. Thirteen patients required transfusion in the non operated group, the mean values of the Pediatric Trauma Score (PTS) was 11.3. The mean lowest hemoglobulin(LHb) was 9.1 g/dL. The mean value of three cases with extraabdominal injuries were 9.0 and 8.3 g/dL respectively. The average amount of transfusion was 17.3 ml/kg. In the operated group, 2 cases were transfused an average of 139.8 ml/kg and their mean PTS was 5 and LHb was 6.6 g/dL. In one out of 16 non-operated cases, intrahepatic hematoma developed and but resolved conservatively. However, two out of 3 operated cases suffer complications such as an intubation granuloma and an intraabdominal abscess with wound dehescence. In conclusion, non-operative management in child with blunt abdominal trauma was safe in Grade I and II solid organ injuries. The decision for operation should be based on the hemodynamic stability after initial resuscitation including transfusion.

Purpose The study was designed to recognize radiation dose by scatter ray of Z axis that patient receives when examine brain CT and measured patient dose that medical team or protector in the CT room. Materials and Methods The research plan was compared to computer tomography of 5 devices that G company’s SDCT, 4 MDCT, 8 MDCT, 16 MDCTwere each 1, P company’s 40 MDCT during brain CT. first method, measured scatter ray of Z-axis at 20cm to 80cm by using ionization chamber. Second, measured by using survey meter at 50cm to 200cm in the CT room. Results 1. TheCTDI was measured on a CT dosimetric phantom by using a pencil ionization chamber for a brain CT which was 9.9mGy in SDCT(120kVp, 100mAs, 5mm section thickness) from the isocenter and 4 MDCT was 15.5mGy, 8 MDCT was 15.8mGy, 16 MDCT was 17.4mGy, 40 MDCT was 15.1mGy and total MDCT average dose rates was 15.95±1.0mGy. 2. Scatter exposure rates were obtained from scattered radiation at distances of 20cm and 80cm from the isocenter by 20cm space. It was decrement dose rates each 0.101mGy, 0.035mGy, 0.013mGy, 0.003mGy(65.3%, 62.9%, 77%) in SDCT and MDCT measured were 0.226mGy, 0.055mGy, 0.022mGy, 0.011mGy(76%, 60%, 50%). 3. Scatter ray was measured on a CT room by using a survey meter which was 0.87mR in SDCT at 50cm from the isocenter by 100mAs and 4 MDCT was measured 2.48mR, 8 MDCT was 2.73mR, 16MDCT was 2.95mR, 40 MDCT was 2.23mR. Average scatter ray dose rates was 2.59±0.3mR in total MDCT, in which compared with the SDCT was increased 66.4%. 4. Scatter exposures were measured with placement of a lead apron on the survey meter adjacent to the scanning, lead apron reduced the scattered exposure by 95.6% at distance of 50cm in SDCT and radiation reduced by 96.6% in MDCT. Scatter exposure rates were obtained from scattered radiation at distances of 100cm and 200cm from the isocenter by 50cmspace. It was reduced by 92.3%, 91.2%, 89.7% in SDCT and MDCT was measured 94.8%, 93.7%, 92.5%. Conclusion We can try reduce radiation dose because sensitive pediatric patient’s or medical team who taken by unnecessary scatter ray and so must use apron or protector during CT examination.

종교는 과연 필요한가?

김경재(Kyung Jae Kim) 전남대학교 종교문화연구소 2008 종교문화학보 Vol.5 No.-

이 논문의 논제 “종교는 과연 필요한가?” 라는 다소 도발적인 제목은 21세기 현대사회에서 종교가 당면한 위기의식을 대중적 표현으로 드러낸 표제다. 현대서구 정신사 속에서, 종교의 무용론과 허구성과 그 해악성에 대한 비판적 사상가들로서 니이체, 프로이드, 마르크스, 그리고 현대 분자생물학자 도킨스 등을 대표로 언급할 수 있다. 논자는 먼저 이들의 종교비판의 요지 중 현대사회에서 특히, 한국 사회에서 여전히 경청해야 할만한 요지들을 간추려 요약했다. 그러나, 폴 틸리히의 표현을 빌린다면, ‘종교 혹은 신앙은 인간의 궁극적 관심’이다. 궁극적 관심으로서의 종교는 이 논문 서두에 소개한 종교비판가들의 비판으로써 난파당하는 것이 아니다. 그들은 왜곡된 종교들, 타락한 종교들에 대한 비판으로서는 타당한 면이 있다. 그러나 본래적 의미에서의 종교, 생동하는 신앙의 순기능은, 죤 힉의 표현을 빌려 말하면, “ 자기중심적 존재인 인간을 창조적으로 변화시켜 실재중심의 인간에로 변화” 시키는데 있다. 이러한 인간존재의 존재론적 전환은 ‘무명과 죄에 매인 인간’을 개방적 존재로, 자유로운 존재로, 사랑하고 자비행을 실천하는 인간으로 변화시킨다. 이러한 존재의 변화능력이 종교의 진면목이며, 전통종교들의 교리체계나 상징 의례면에서의 다양한 차이에도 불구하고 세계적 종교에서 발견되는 공통된 특징이다. 제 2차 바티칸 회의 (1962-65) 이후, 세계 지성세계는 종교의 다양성을 인정하고, 상호대화, 상호협력을 넘어서, 서로 배움을 통한 자기종교의 창조적 변화까지를 두려워하지 않는 깨달음에로 나아가고 있다. “등잔의 모양은 다양하나 불빛은 같다”라는 신비가의 은유적 표현에 동의한다. 세계지구촌사호에서도 그렇거니와, 한국사회에서도 셈족계 종교 특히 그리스도교의 오만과 우월의식이 비판대상이 되고 있다. 오늘날 종교지도자들의 도덕적 -영적 지도력 상실만이 아니라, 성숙해진 현대사회인의 가치관과 실재관을 따라가지 못하는 형국이다. 이 글에서 필자는 종교가 오늘과 미래사회에서도 여전히 필요하고 인간사회를 건강하게 만드는데 순기능으로 작동하기 위해서 몇 가지 필수적으로 변화해야할 쟁점들을 제시하였다. 건강한 종교는 개인을 정화시키는 인간내면성의 변화와 함께 사회 구조적 악과 모순을 극복하는데 노력해야 한다. 상징적으로 표현한다면, 신(종교)과 혁명(정치)이 하나 되어야 한다. 인격적 유신론과 동양종교의 비인격적 공사상, 그리고 역사지향적 서구종교와 우주지향적 동양종교의 상호통전이 이뤄져야 한다. 무엇보다도, 종교가 현대인에게 의미를 갖는 실재가 되려면, 권위적 가부장문화에 침윤된 전통종교 모습에서 탈바꿈하여 자비와 긍휼심을 핵으로 하는 모성적 종교의 영성에로 전화되어야 하며, 권력지향적 국가종교 이데올로기로부터 스스로 해방하여 억압받고 가난한 사람들을 돕고 해방시키는 종교에로 탈바꿈해야 할 것이다. Is religion requisite just as one thought for the contemporary society? In this provocative theme, I will attempt to evaluate critically some negative influences of modern religions on sociocultural human life, and then to propose the urgent transformations of the korean religions in meeting the needs of the times. In this article, I attempt to trace and analyze the criticism on the deteriorate religion from F. Nietsche, S. Freud, K. Marx, and R. Dawkins. And then I try to propose some corrections of shortcomings in regards to Korean religious situation. Faith is, according to P. Tillich, the state of being ultimately concerned. Since faith as the authentic religious phenomenon is an act of the most centered act of the human mind, it participates in the dynamics of personal life and transforms the personality as a whole toward a creative new being. In Hick's views, this radical change of human being means a transformation of human existence from self-centeredness to Reality-centeredness. This creative transformation is essentially the same occurrence within the different religious traditions. It may be that, in the words of a muslim mystic, “the lamps are different but the light is the same”. Since Vatican Council II (1962-65), the actual attitudes of the mature man of faith have been implicitly pluralistic. It has become obvious that we are living at a turning point in the history of religion. Appreciative understanding of other religious traditions in terms of religious pluralism has become widespread globally, and criticism of the arrogance and imperialism of Christianity is commonplace in Korean society as well as world one. In 21st century era, the living world religions have attempted to take into account the purification of the person and the humanization of the social structure . That implies, in other words, the unification of God and revolution, the reconciliation of the Real as personal God with the Ultimate Reality as Emptiness, Change from the authoritative partriarch-religion to the compasionate matriarch-religion, and the integration of historical religion and cosmic religion, and finally change from the Emperor sanctioned religion to the religion for the oppressed and the poor.

The quantity of discharged oil from a compressor is one of the most important issues for proper operation of refrigeration system. If the oil is increased in the system not only pressure drop is increased in other components, such as evaporator and gas cooler but also heat transfer coefficient in the heat exchangers is decreased. In addition, the lack of oil in the compressor may cause a critical of the system failure. In this study, one stage single rotary compressor is used for measuring oil circulation ratio(OCR). Carbon dioxide and PAG oil are used as refrigerant and lubricant. Using a U-tube densimeter, mixture density is measured. Characteristics of oil circulation ratio have been investigated for CO₂ rotary compressor in the range of operation frequency 45 ㎐ to 63 ㎐ and the suction temperature range of 0℃ to 15℃. The results obtained indicate that the oil circulation ratio is increased as the suction temperature or compressor operating frequency is increased.

The oil separation in an oil separator is one of the most important characteristics for proper compressor operation. In this study, a gravity type of oil separator is used. Oil separation characteristics has been investigated for CO2/PAG mixture in the range of oil concentration 0 to 5 weight-percent and the mixture temperature range of 0℃ to 15℃ and 70℃ to 90℃. The results obtained indicate that the oil separation is increased with an increase in the oil concentration. It is also found that the oil separation in liquid state is increased with an increase in the mixture temperature while the oil separation in gas state is decreased.
