A comprehensive experimental and numerical study has been conducted to understand the influence of $CH_{3}Cl$ addition on $CH_4/O_2/N_2$ premixed flames under the oxygen enrichment. The laminar flame speeds of $CH_4/CH_{3}Cl/O_2/N_2$ premixed flames at room temperature and atmospheric pressure are experimentally measured using Bunsen nozzle flame technique, varying the amount of $CH_{3}Cl$ in the fuel, the equivalence ratio of the unburned mixture, and the level of the oxygen enrichment. The flame speeds predicted by a detailed chemical kinetic mechanism employed are found to be in excellent agreement with those deduced from experiments. Even though the molar amount of $CH_{3}Cl$ in a methane flame is increased, temperature at the postflame is not significantly varied, but the calculated heat release rate and emission index of NO are largely decreased for the oxygen enhanced flame. The function of $CH_{3}Cl$ as inhibitor on hydrocarbon flames becomes weakened as the level of the oxygen enrichment is increased from 0.21 to 0.5.

목적: 수술 전 동시병용 방사선-항암 화학 요법의 초기 치료성적과 급성 부작용에 대해 알아보고자 하였다. 대상 및 방법: 1999년 6월부터 2002년 4월까지 T3또는 T4 병기의 직장암으로 진단 받고 완전절제가 어렵거나, 종양이 하부직장에 위치하여 수술 시 항문 괄약근의 보존이 불가능하리라고 예견된 40명의 환자에게 수술 전 동시병용 방사선-항암 화학요법을 적용하여 37명의 환자가 수술 전 치료방침을 완료하였다. 방사선치료는 전 골반부에 일일 1.8 Gy씩 5주간에 45 Gy를 엎드린 자세로 조사하였다. 항암 화학요법은 경구 UFT와 Leucovorin (LV)(12명), 정주 5-fluorouracil (FU)와 LV (10명), 정주 5-FU 단독요법(일시 정주 10명, 지속 정주 5명)을 각각 시행하였다. 수술은 수술 전 치료 종료 후 4$\~$6주경에 예정하였으며 35명에 대해서 수술을 시도하였다. 결과: 본 연구의 수술 전 방사선-항암 화학요법에 대한 순응도는 매우 높았. (92.5$\%$, 37/40). 수술 전에 간과 폐에 새로운 원격전이가 확인된 2명을 제외한 35명의 환자에서 절제수술을 시도하였고, 22명(62.9$\%$)에서 항문 괄약근의 보존이 가능하였으나, 2명(5.7$\%$)은 개복 후 절제수술을 포기하였다. 절제수술을 시행한 33명 중 30명은 육안적 완전절제를, 1명은 육안적 불완전절제를 시행하였으며 2명은 병리소견에 관한 정보를 얻을 수 없었다. 수술 및 병리소견에 근거한 병기하강률은 45.5$\%$ (15/33), 절제연 음성 완전절제율은 78.8$\%$ (26/33)였다. 수술 전 방사선치료 도중 급성 부작용으로 Grade 3$\~$4 호중구 감소가 4명(10.8$\%$)에서 발생하였다. 절제수술 후 국소 재발이 12.1$\%$ (4/33), 수술 전 치료방침 완료 후 원격 전이는 21.6$\%$ (8/37)에서 각각 나타났으며, 3년 생존율은 87$\%$였다. 결론: 직장암에 대한 수술 전 동시병용 방사선-항암 화학요법은 낮은 부작용으로 높은 수술절제율, 병기하강률, 완전절제율, 항문 괄약근 보존율 등을 얻을 수 있는 효과적인 방법으로 판단되며 앞으로 장기간에 걸친 추적관찰을 요한다. Purpose: To report the early results of preopeartive concurrent radio-chemotherapy (CRCT) for treating rectal cancer. Materials and Methods: From June 1999 to April 2002, 40 rectal cancer patients who either had lesions with a questionable resectability or were candidates for sphincter-sacrificing surgery received preoperative CRCT. Thirty-seven patients completed the planned CRCT course. 45 Gy by 1.8 Gy daily fraction over 5 weeks was delivered to the whole pelvis in the prone position. The chemotherapy regimens were oral UFT plus oral leucovorin (LV) in 12 patients, intravenous bolus 5-FU plus LV in 10 patients, and intravenous 5-FU alone in 15 patients (bolus infusion in 10, continuous infusion in 5). Surgery was planned in 4$\~$6 weeks of the completion of the preoperative CRCT course, and surgery was attempted in 35 patients. Results: The compliance to the current preoperative CRCT protocol was excellent, where 92.5$\%$ (37/40) completed the planned treatment. Among 35 patients, in whom surgery was attempted after excluding two patients with new metastatic lesions in the liver and the lung, sphincter-preservation was achieved in 22 patients (62.9$\%$), while resection was abandoned during laparotomy in two patients (5.7$\%$). Gross complete resection was peformed in 30 patients, gross incomplete resection was peformed in one patient, and no detailed information on the extent of surgery was available in two patients. Based on the surgical and pathological findings, the down-staging rate was 45.5$\%$ (15/33), and the complete resection rate with the negative resection margin 78.8$\%$ (26/33). During the CRCT course, grade 3 $\~$4 neutropenia developed in four patients (10.8$\%$). Local recurrence after surgical resection developed in 12.1$\%$ (4/33), and distant metastases after the preoperative CRCT start developed in 21.6$\%$ (8/37). The overall 3-years survival rate was 87$\%$. Conclusion: Preoperative CRCT in locally advanced rectal cancer is well tolerated and can lead to high resection rate, down-staging rate, sphincter preservation rate, however, longer term follow-up will be necessary to confirm these results.

현재의 방사선 치료의학은 고도로 발전하여 다양한 기술의 방사선 치료기술(IMRT, SRS, 3D-RT, 등)이 행하여지고 있다. 자궁경부암의 방사선 치료나 직장암의 방사선 치료에서는 아직까지 보편화된 치료법인 3문조사법이나 4문조사법을 실시하고 있다. 2차원 치료 시 치료부위 피부에 방사선에 의한 화상이 생기게 된다. 이러한 피부 부작용은 방사선 치료의 대표적인 부작용이라 할 수 있다. 지금까지는 피부선량 측정에 있어서 1회 측정으로 총 치료기간을 환산하여 피부선량을 기술하였다. 본 연구에서는 환자의 매회 치료 시 마다 피부선량을 측정하였다. 피부선량 측정에는 누적선량 측정에 적합한 유리선량계를 사용하였다. 피부선량 측정 후 치료계획 장치에서 측정한 피부선량과 비교 분석하였다. 치료기간 동안 매번 측정한 피부선량과 치료 계획 장치에서 계산한 선량을 서로 유의성 분석을 실시한 결과 유의하다는 결과를 없었다. 환자치료 시 움직임에 의한 오차가 있음에도 치료 계획 장치의 계산 선량과 비교하여도 오차범위에 합당하였다. Recently a variety of high technologies for radiation therapy (IMRT, SRS,. 3D-RT, etc.) has been developed. For the cervical and rectal cancer, 3field or 4field radiotherapy have been applied to the patients. In the case of two-dimensional treatment, one of the most typical side-effects is skin burn due to the radiation irradiation. In general the skin dose is evaluated by only a single measurement during the whole treatment period. In this study, however, skin dose was measured in each radiation treatment and the total skin dose was accumulated in a glass dosimeter through all the cases. After simulating the skin dose from treatment planning system, the results were compared with the actual skin doses. The results showed a good agreement between two data sets. Even though there are certain amount of errors caused by the patient movement along the treatment, the difference between actual dose and simulated dose was within the accepted range of error.

초등 체육수업에서의 교사의 피드백 분석

신성수(Shin Seong Su) 한국체육교육학회 2002 한국체육교육학회지 Vol.6 No.2

This study is designed to present information necessary for the enhancement of efficiency of physical education through the analytic study of teachers` feedbacks in elementary schools` P.E. With this in mind, the researcher made an analysis of the relationship between feedbacks and ALT-PE, the cause of the time spent by feedback pattern, and the relationship between feedbacks and class flow as a vehicle for a statistical approach method, and at the same time put to use a qualitative approach method by working with two teachers with a high ratio of feedback and two teachers with a low ratio of feedback. In order to achieve the purpose of this study, the researcher worked with a total of 30 teachers in charge of the third and fourth graders at elementary schools at North Chungcheong Province, recording mat-based activities(the scene of students rolling back and forth on a mat) with the aid of a video camera. The researcher analyzed ALT-PE with the help of an interval observation record(six-second observation, six-second record), calculating the percentage of the variables of teaching behavior including feedback on the basis of five-second observation and five-second record with the help of SPSS Ver 10.0 and collecting materials based on class observation, in-depth interviews and descriptive statements by working with the four subjects. The researcher has come to the following conclusions based on the method and procedures of this study. First, the analysis of the correlation between feedbacks and ALT-PE shows that there was no significant correlation between each feedback pattern and ALT-PE. This resulted from the fact that feedbacks, which were required for the accomplishment of learning objectives for lack of contents-knowledge about class assignments, were not realized and that there was no proper feedback after supervision in consideration of a significant negative correlation between supervision and feedbacks. Second, the analysis of the cause of ALT-PE consumption by feedback pattern indicates that the ratio of feedbacks was lower than other teaching behavior and that static behavior feedbacks were more than other feedbacks. This result is attributable to the fact that teachers full or bereft of feedbacks were lacking in abilities to command linguistically and functionally proper feedbacks in the real situation of class for lack of previous training and field training and that their feedbacks were limited to only daily praises for lack of established teaching materials. Third, feedbacks were presented more at stages of unfoldment and settlement. Static behavior feedbacks in particular were more freely used at these stages and static skill feedbacks were least freely used. And negative feedbacks were relatively frequently used at these stages. These results were due to lack of knowledge about learning assignments on the part of teachers and passive supervision

『詩經』에 나타난 占術文化 연구

신성수 ( Sung Soo Shin ) 경희대학교 인문학연구원 2013 인문학연구 Vol.0 No.23

점술문화는 동서양을 막론하고 고대사회의 문화적 특징 가운데 하나이다. 이 논문에서는 동양에서 가장 오래된 문헌인 『詩經』을 통하여 고대 중국인의 점술문화를 살펴보았다. 『시경』속에 담겨 있는 점술문화의 특성을 다음과 같이 정리할 수 있다. 첫째, 『시경』에 나타난 점술유형과 『周禮』에 기술된 점술유형을 볼 때, 占卜과 占筮 그리고 占夢이 고대 점술문화의 원형임을 확인할 수 있다. 둘째, 『周易』筮法과 관련하여 .蓍의 재료가 되는 蓍草가 당시 널리 퍼져 있는 식물이라는 것을 확인할 수 있다. 셋째, 占은 인간의 실존적 삶의 과정에서 펼쳐지는 극한 상황에서 인간으로서의 선한 召命을 받고자 하는 간절한 의도에서 행해졌음을 확인할 수 있다. 그렇지만 지나치게 남용되는 점술로 인한 폐단을 지적하는 내용도 있음을 알 수 있다. 넷째, 『시경』에서는 占星과 관련한 내용은 단 한 군데에 불과했다. 다섯째, 고대사회에 都邑을 정하거나 옮기기 전에 반드시 거북점을 쳤다는 사실을 확인할 수 있다. 첨단 과학문명으로 치닫고 있는 현대사회에도 동서양을 막론하고 점술문화가 여전히 존재하고 있다. 시대와 문명이 달라져도 인간에 내재된 보편적 정서는 달라지지 않는다. 현대인의 생활이나 정서 속에는 고대로부터 형성된 점술문화의 근원적 양상이 여전히 존재하고 있다. 『시경』속의 점술문화와 정서는 지금 이 시대에도 현대인의 실존적 삶 속에 투영되어 있다고 볼 수 있다. In both East and West, divination was one of the cultural characteristics of ancient societies. This paper, explores the divination culture of the ancient China as it is reflected in the Book of Odes(詩經). The Book of Odes is one of the oldest Eastern classics, in which the divination culture of the ancient times has been kept well. The results of this study are as follows: First, the Divination by baked tortoiseshells(占卜), divination by plant sticks(占筮) and divination by dreams(占夢) of ancient divination type was the prototype of the divination culture. Second, divination was conducted for the purpose of finding a solution for the human existential predicament that occurs in the course of life. However, there also happened to be excessive use of divination that aggravated the life of the divination seekers. Third, in the ancient times, divination by baked tortoiseshells (占卜) was also used when the capital city was moved. In modern society, either in East or in West, divination culture is still present. In spite of differences in age and culture, human emotions which are universal do not change radically. Modern life and the emotions, ultimately deriving from the ancient culture, is still pervaded by the desire to know in advance about the future. Divination culture and sentiment in the Book of Odes, even in the age of modern existence, is still effective to illuminate the desire of the human mind for divination.
