TThe results based on Toegye's thought of the body such as the above are as follows : 1.Toegye's thought of the body means Igi Theory(the theory on reason and energy). The above Toegye's thought of the body is based on Igi Theory(the theory on reason and energy). Human body based on I(reason) is made of Gi(energy), and then Yi Toegye maintains that a human should be himself as the master of action. 2. Toegye's meaning of the body based on Igi Theory(the theory on reason and energy) is made of Gi(energy) with the beginning of I(reason). Therefore the today's meaning of the body is considered as Some and Body. 3. Toegye maintains on the basis of his so called Igihobal Theory that since the mind and body of human being are inseparably related to each other, they are simultaneously generated, and that man thus exists as a mental and physical being with both of them. This view of the relationship between mind and body with the theory of psychosomatic units that human mind and body are in inseparable relation, which is today a viewpoint of body in Physical Education.

Among the school gymnastics facilities, perhaps the most common ones are gymnastics apparatus. That's why a historic study in the event of havy gymnastics is required. The researchers here have examined the origin of gymnastics with apparatus centered on Jahn's "turen" exercise. The results are as follows : 1. Heavy gymnastics originally contained a lot of elements from field and track events. It had aims of obtaining natural physical movement and enhancing work efficiency. 2. An outdoor event turnen was banned and changed into an inddor event. The fact that apparatus gymnastics is nowadays held indoors reveals the decisive influnece of Jahn's turnen exercise. 3. Jahn's balance beam exercise was at first played for the purpose of blancing oneself and merely for fun. It has developed into the present from through wide distribution and elaboration. 4. Jahn first used the term of parallel bars and the present women's event of parallel bars resembles Jahn's. 5. Jahn's horizontal bars have also had a great effect on today's event of horizontal bars.

감용제 limonene을 이용하는 EPS 자원 재활용 공정에 있어서, limonene - EPS 혼합 액체의 저장 · 취급시의 화재위험성 평가에 대한 기초 자료로 제시하고자 혼합물의 농도 및 시료량의 변화에 따른 최저발화온도를 측정하였고, 발화와 비발화 영역을 비교하였다 발화온도를 예측하는데 있어서 가장 과학적인 원리로서 이용되고 있는 발화 지연 시간, 활성화 에너지 및 발화온도의 관계식을 선형회귀분석을 이용하여In t= 0.704/T -5.819로서 제시하였다. 또, 가연성 혼합물의 농도 변화에 따른 발화위험성을 예측하기 위하여 혼합물의 농도와 발화온도의 관계식을 비선형회귀분석을 이용하여 T_(m)=248.32+69.27X+172.60X²로서 제시하였다. 그 결과, 발화 지연 시간과 발화온도와의 관계식 및 혼합물의 농도와 발화온도와의 관계식에 의해서 limonene - EPS혼합물의 발화온도의 추정이 가능하게 되었다. In the reutilization process using limonene, the organic solvent to reduce volume of EPS, the AIT was measured with the variation of concentration and volume of mixture, in order to present the fund-mental data on the fire hazard assessment of limonene - EPS mixture at storage and handling. And ignition zone was compared with non-ignition zone. The equation related to AIT, activation energy and ignition delay time, used by the most scientific basis for predicting AIT values, was suggested using linear regression analysis as In t = 0.704/T - 5.819. And the equation related to concentration of mixture and AIT was also suggested to predict ignition hazard of combustible mixture using nonlinear regression analysis as T_(m)= 248.32 + 69.27X + 172.60X², It enabled to predict ignition temperature according to variation of ignition delay time and concentration of mixture by the suggested equations.

이종영,강승원,하명화,김중구,배삼덕,김두희,남복동 大韓産業醫學會 1996 대한직업환경의학회지 Vol.8 No.2

포항 지역 한 철강 제조업에서 1995년 1월부터 10월 사이에 실시한 정기 건강진단을 받은 남자 근로자 11,523명을 대상으로 HBsAg 및 Anti-HBs, HBeAg 및 Auti-HBe은 EIA법으로, SGOT 및 SGPT는 반응속도법(IU)으로 검사하였다. 그리고 이들 대상자에서 교육정보, 근무 형태, 음주 및 흡연습관과 간기능 이상 여부를 조사하여 다음과 같은 결과를 얻었다. 1. B형 간염 표지자의 분포를 보면 HBsAg(+)/Anti-HBs(-)는 8.1%, HBsAg(-)/Anti-HBs(+)는 60.5% 그리고 HBsAg(+)/Anti-HBs는 0.1%이었으며, HBsAg의 양성율은 8.2%, Anti-HBs 양성율은 60.6%이었다. 2. 연령에 따라 HBsAg(+)/Anti-HBs(-)와 HBsAg(-)-HBs(+)가 유의하게 증가한 반면(p<0.05), 교육정도와 근무형태에 있어서는 통계적으로 유의한 차이가 없었다. 3. 음주율은 HBsAg(+)/Anti-HBs(-)에서 HBsAg(-)/Anti-HBs(-)와 HBsAg(-)/Anti-HBs(+)의 84.6% 및 85.7%에 비해 낮지만 73.9%나 되었고, 흡연율은 HBsAg(-)/Anti-HBs(+), HBsAg(+)/Anti-HBs(-) 및 HBsAg(-)/Anti-HBs(-)에서 54.3%, 53.7% 및 53.0%의 순서로 나타났다. HBsAg(+)/Anti-HBs(-)에서 간기능 이상자가 40.1%이었으나 HBsAg(-)Anti-HBs(-)와 HBsAg(-)/Anti-HBs(+)에서도 각각 21.9% 및 18.4%를 차지하였다. 4. HBsAg(+)에서의 e항원에 대한 표지자의 분포를 보면 HBeAg(+)/Anti-HBe(-)는 31.3%, HBeAg(-)/AntiHBe(+)는 55.0% 그리고 HBeAg(+)/Anti-HBe(+)는 1.6%이었고 HBeAg(+)/Anti-HBe(-)는 연령에 따라 감소하고 HBeAg(-)/AntiHBs(-)와 HBeAG(-)/AntiHBe(+)는 증가하였다. HBsAg 양성자중 HBeAg의 총 양성율은 32.9%로 연령이 증가할수록 유의하게 감소하였다. 본 연구는 근로자의 B형 간염 표지자 조사에 있어 Anti-HBs의 검사에서는 EIA 방법으로 실시해야 하는 근거를 제시하는 것이며, 철강산업 근로자에서는 B형간염 이외의 간장질환에도 관심을 가져야 할 것으로 보이며 음주 문제에 대한 대책마련이 시급히 이루어 져야 할 것으로 생각된다. A study for seroprevalence of Hepatitis B virus markers (HBsAg, Anti-HBs, HBeAg and Anti-HBe) by EIA method and the Liver Function Test(SGOT and SGPT) using kinetic method was carried out from January to October 1995 among male workers of a major iron and steel manufacturing company located in Pohang. The results were as follows; 1. The distribution of hepatitis B virus markers showed that the proportions of HBsAg(+)/Anti-HBs(-), HBsAg(-)/Anti-HBs(+) and HBsAg(+)/Anti-HBs(+) were 8.1%, 60.5% and 0.1%, respectively. The positive rate of HBsAg in all subjects was 8.2%, whereas that of anti-HBs was 60.6%. 2. The proportions of HBsAg(+)/Anti-HBs(-) and HBsAg(-)/Anti-HBs(+) increased significantly with age. While the distribution of hepatitis B virus markers exhibited no significant differences among the groups classified by educational background or work type. 3. The proportion of drinkers in HBsAg(+)/Anti-HBs(-)(73.9%) was significantly lower than those of HBsAg(-)/Anti-HBs(-) and HBsAg(-)/Anti-HBs(+) (84.6% and 85.7%, respectively). The proportions of smoking for the three groups of HBsAg(-)/Anti-HBs(+), HBsAg(+)/Anti-HBs(-) and HBsAg(-)/Anti-HBs(-) were 54.3%, 53.7% and 53.0%, respectively(p<0.01). The proportion of the subjects with abnormal liver function test in HBsAg(+)/Anti-HBs(-) was 40.1%, whereas those in HBsAg(-)/Anti-HBs(-) and HBsAg(-)/Anti-HBs(+) were 21.9% and 18.4%, respectively. 4. The distribution of e Ag markers among HBsAg(+) subjects showed that the proportions of HBeAg(+)/Anti-HBe(-), HBeAg(-)/Anti-HBe(+) and HBeAg(+)/Anti-HBe(+) were 31.3%, 55.0% and 1.6%, respectively. The proportion of HBeAg(+)/Anti-HBe(-) decreased significantly with age and those of HBeAg(-)/Anti-HBe(-) and HBeAg(-)/Anti-HBe(+) increased with age. The positive rate of HBeAg among HBsAg(+) subjects was 32.9%. In conclusion, as a screening method, EIA is recommended to test hepatitis B virus markers, especially when examining Anti-HBs more sensitively. For the workers of the iron and steel manufacturing company studied, liver diseases caused by other than hepatitis B should be given a special care including an education avoiding alcohol drinking.

The low temperature storage method has been used to increase the value of agricultural products by reducing quality deterioration and controlling respiration rate. The respiration rate of agricultural products depends on several factors such as temperature, moisture, gas composition and microbe inside the storage room. Among that temperature is the most important factor, which affects respiration rate and causes severe damage. The results obtained from these experiments are that electric consumption is decreased as setting temperature is decreasing and temperature deviation is increasing. In the ventilation experiment, the case ventilated four times a day(every six hours a day) with ten minutes operation each time, was inspected require as much electric consumption as non-ventilation case.

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.

Dong Wan Kim,Soo Hyuk Lee,Jun Ho Choi,Jae Ha Hwang,Kwang Seog Kim,Sam Yong Lee Korean Cleft Palate-Craniofacial Association 2023 Archives of Craniofacial Surgery Vol.24 No.3

Background: Midfacial fractures frequently involve the maxillary sinus, leading to maxillary sinus pathology. We aimed to examine the incidence and contributing factors of maxillary sinus pathology in patients who underwent open reduction and internal fixation (ORIF) for midfacial fractures. Methods: A retrospective analysis was conducted on patients who underwent ORIF for midfacial fractures at our department over the past 10 years. The incidence of maxillary sinus pathology was identified clinically and/or by computed tomography findings. Factors that significantly influenced the groups with and without maxillary sinus pathology were examined. Results: The incidence of maxillary sinus pathology in patients who underwent ORIF for midfacial fractures was found to be 11.27%, with sinusitis being the most common pathology. Maxillary sinus pathology was significantly associated with the presence of a blowout fracture involving both the medial and the inferior orbital walls. Factors such as sex, age, diabetes mellitus, hypertension, smoking, inflammatory disease, follow-up period, use of absorbable plates, and use of titanium plates did not have a significant impact on the development of maxillary sinus pathology. Conclusion: The incidence of maxillary sinus pathology in patients who underwent ORIF for midfacial fractures was relatively low, and in most cases, it resolved without the need for specific treatment. Consequently, there may not be a significant need for concern regarding postoperative maxillary sinus pathology.
