Purpose: To evaluate the antiadhesive effects and safety of an oxidized regenerated cellulose (Interceed) after thyroidectomy. Methods: Seventy-six thyroidectomized patients were prospectively randomized into two groups with regard to the use of Interceed. We evaluated each group for their adhesive symptoms using four subjective and four objective items at the 2nd week, 3rd and 6th month after thyroidectomy. All patients were examined for vocal cord motility by indirect laryngoscope at each period. Results: Total adhesion scores at each postoperative follow-up period decreased with time, but were not significantly different in each group. The median score for swallowing discomfort for liquid was significantly lower in the Interceed group than in the control group 2 weeks after surgery. In addition, the severity of skin adhesion to the trachea was reduced in the Interceed group compared with the control group 6 months after surgery. During the study, there were no adverse effects or significant differences in postoperative complications between the groups. Conclusion: Interceed appeared to be safe and effective in improving neck discomfort at early postoperative periods and preventing skin adhesion to the trachea 6 months after thyroidectomy.

To determine as optimal sowing time of forage rape in spring time in southern areas of Korea, forage rape cv. Velox, the highest yielding variety among introduced varieties of forage rape, was grown under five different sowing times. Yield components such as plant length, number of branches and number of leaves etc. were higher at the sowing time of Mar. 15 and Mar. 25. The plants sown at Mar. 15 and Mar. 25 also showed highest fresh and dry matter yield. When plants were grown under later sowing time, they showed higher values in content of crude protein and lower values in contents of crude fiber such as Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), cellulose and lignin. There was no relationship between variation of In Vitro Dry matter Digestibility (IVDMD) and sowing time. The plants sown at Mar. 15 and Mar. 25 showed highest digestible dry matter yields.

The leiomyomas of the vulva are rare benign tumors the incidence is 0.024%~0.55% in women. There are no relationship between leiomyomas of the vulva and uterus. But there are some reports that leiomyomas of the vulva and uterus simultaneously. The leiomyomas of the vulva present without symptoms and excision with biopsy is treatment of choice. Tumors of the gynecological apparatus may present without symptoms, or they may mimic other common gynecological conditions. Because of this, any vulva mass must be considered cautiously. We reported this case with a brief review of the concerned literatures.

To find out the optimum fertilizer level for high yielding variety, Velox, experiment was conducted with 15 compositions of fertilizer levels at the experiment field of forage crop in Sunchon National University from Mar. 2000 to Aug. 2000. The effects of nitrogen fertilizer on plant growth were significant but increasing rate of application in potassium and phosphate fertilizers above 6 kg/a had negligible effects on plant growth. The optimum nitrogen application level of fertilizers turned out to be 16-6-6 kg/l0a of N-P2O5-K5O. Content of crude protein was highest and that of crude fiber such as NDF, ADF, cellulose and lignin were lowest at this rate of fertilizer application. Furthermore, IVDMD was high and dry matter yield were highest at the optimum raterate

This study was conducted to investigate the relationships between yearly variations of meteorological elements and yearly variations of productivity in rice. In addition, correlation coefficients among yield and yield components were used to find out the relationships between meteorological elements and productivity. Yearly variation of the mean air temperature in May was large with coefficients of variation(C.V.) of 25.0%, but the variation of the duration of sunshine in May were relative small. No. of panicles per hill and 1,000 grains wt. of brown rice were great with C.V. of 21.1, 19.7%, respectively, brown rice yield show more or less C.V. of 5.5% and milled rice show still less variation. Correlation coefficients between temperatures in period of cultivation from May and yield were positive correlations. Correlation Coefficients between precipitation in period of cultivation from Sep. to Oct. and yield are positive correlations. Correlation coefficients amount the panicle length, no. of panicles, no. of spikelets, ratio of ripened grains, 1,000 grains wt. of brown rice, milled rice yield, brown rice yield and milled rice yield were positively significant at the level of 1 %, respectively.

The conventional non-invasive and invasive technique have limitations in evaluating cardiac prosthetic valves and artificial valves. We have used continuous wave Doppler echocardiography to evaluate 48 patients with tissue and mechanical mitral valves implanted within 4 months prior to examination. The results are as follows. 1) Of these patients, male are 28. The mean ages of male are 35.60 (yr) and female are 41.82. 2) The differences of peak and mean velocities of prosthetic acardiac valves between male and female are not significant, but the differences of valvular size between male and female are significant(male:31.00±1.30(mm), female:29.36±2.11, p<0.01). 3) The difference of size and flow velocities between mechanical (Edwards-Duromedics) and tissue(Ionescue-Shiley) valves are not significant, but the ages of patients with mechanical valves are significantly lower than tissue valves(mechanical valve; 34.05±11.28, tissue valve; 43.62±11.26, p<0.01). 4) The differences of flow velocities between mechanical and tissue valves, sizes of which are 31mm, are significant statistically (peak velocity; 130.15±24.59 vs 110.00±19.41, mean velocity; 74.49±23.14 vs 51.38±12.71, p<0.01). 5) The sizes of valves are larger, the peak and mean velocities are lower, but it is not significant statistically. The results indicated that Doppler echocardiography is a useful method for evaluating function of prosthetic valves.

이 연구는 유교, 특히 조선 성리학의 도덕교육에 의한 인격변화의 과정과 그 결과를 컴퓨터로 모의 실험하기 위하여, 조선 성리학자들이 이해했던 心의 구조와 그 작동의 모형을 작성해보고자 하는 데 그 궁극적인 목적이 있다. 아울러 그것을 통해서 조선 성리학의 큰 줄기를 형성한 퇴계의 심학과 율곡의 심학을 연구대상으로 포용하고, 그 둘 사이에 나타나는 차이점과 공통점을 살피고, 그 결과를 근거로 일종의 성리학 통합심성모델을 작성해보고자 할 때 필요한 이론적 정지작업을 하는 것이 본 연구의 실제 내용이다. 그 작업을 위하여 먼저 통합심성모델 작성의 이론적 관점과 기반으로서 일종의 구성주의의 관점을 채택한 이유를 밝히고, 그것에 의하여 성리학의 심성론의 해석과 그에 따른 심성모델의 구성 방식을 제시하였다. 아울러 서구의 심리철학에서 이해되는 mind, 인지과학에서 연구되고 있는 인간의 마음, 인공지능에서 이해되는 마음을 분석하고 그것과 구성주의에 의하여 재해석된 성리학자들의 마음과의 비교를 행하였다. 중요한 것은 성리학의 역사로 볼 때 똑같이 주자학 계열의 성리학자이면서도 인간의 심성의 관념에 관해서 대립적인 견해를 지녔던 퇴계와 율곡의 관점을 하나로 묶어서 통합심성모델을 작성하는 작업이다. 이에 대해서 본 연구는 퇴계와 율곡이 근본적으로 禮실천에 의하여 인간의 심성의 순수함과 정직함을 기르고 회복하려는 점에서 동일한 입장이라는 점에 착안하여, 사단과 칠정, 인심과 도심 등에 관한 理氣論적 해석에 차이가 있다고 하더라도 그것을 통합해 볼 수 있는 이론적 체제를 확보하고자 하였다. 현대에 논의되는 서구철학적 관점의 윤리학과는 다소 다른 방향과 관점에서 진행되는 이 논의는 인지과학과 비트겐슈타인류의 언어철학 등의 관점과 상호 통하는 면이 있으며, 현대 서구철학의 윤리학이 해결하지 못하는 인간의 도덕적 앎과 행위와의 괴리를 넘어설 수 있는 이론적 가능성을 보여준다고 전망된다. 그 점을 인지과학자인 프란시스코 바레라, 언어철학자인 허버트 핑가레트 등의 이론을 근거로 추론하였다. 결론적으로 퇴계와 율곡의 성리학 심성모델은 현대 윤리교육에 대해서 인간의 심신관계 및 실천지향의 윤리교육의 기초를 제시할 수 있으며, 나아가서 그에 관한 실용성도 풍부하게 지니는 것으로 생각된다. This study has a purpose to make a structure of mind and its working principles, which had been thought and understood by confucians of Chosun Dynasty, for computer simulating processes of peronalyity changes through Chosun Dynasty's moral education. This study includes Simhak(心學) of famous Chosun confucians, Toegye and Yulgok, and compares commons and differences of two scholar's theory. The key of this study prepares a necessary theoretical foundation for making a Neo-confucian integrated mind model from such results. We explained why we adopt radical constructivism as a theoretical framework for the integrated mind model, and proposed an interpretation of Neo-confucian mind theory and a method of constructing mind model. Futhermore, we look around a mind of western psychological philosophy, a mind of cognitive science, and a mind of artificial intelligence, and we have compared the confucian mind which is re-interpreted as radical constructivism with such minds. An important work is to make an integrated mind model of Toegye and Yulgok because two scholars are same Neo-confucian, but assisted own theories about human mind. Although the interpretations of Sadan(四端) and Chiljung(七情), Insim(人心) and Dosim(道心) are different each other, encouraging and recovering purity and honesty human mind with the practice of rituals is very much alike. Therefore we want to prepare theoretical foundation for integrating both. This argument is different from ethics of modern western philosophy, but have something to do with cognitive science and Wittgenstein-like philosophy of language. We expect that this idea show a theoretical possibility beyond the dissociation between ethical thinking and behavior, which modern western ethics can't solve. Such a conclusion is inferred from the concepts of Francisco Valera, the cognitive scientist, and Herbert Figarette, the linguistic philosoper. Now to conclude, the confucian mind model of Toegye and Yulgok can provide the explainable mind-body relationship and the foundation of practical moral education for modern education. We believe that the model has much possibility for practical use.

The purpose of this research is to evaluate indoor office environment using the concentrations of nicotine, 3-enthenyl-pyridine(3-EP), and respirable suspended particulate(RSP), which are indicators for environmental tobacco smoke(ETS) and the correlations between indicators and environmental conditions(smoking density, smoking index). The mean air charge per hour (ACH) in smoking rooms was 10.4 and most of the smoking rooms showed non-compliance withe ASHRAE standard value except only one smoking rooms. The concentrations of RSP, 3-EP, nicotine showed log=normal distributions, and became different statistically depending on smoking condition(p〈0.01). The geometric mean concentration of RSP in smoking room was 441.7 ug/㎡ that is far exceeded environmental standard(150 ug/㎡). This implies that fine particulate in smoking room should be carefully controlled considering smoking density and ventilation fate. The mean concentrations of nicotine and 3-EP were 93.4 ug/㎥, respectively. The correlation coefficients between RSP and SI, 3-EP and SI, and Nicotine and SI were 0.67, 0.84 and 0.74, respectively. The correlation coefficient between nicotine and 3-EP, nicotine and RSP, and RSP and 3-EP were 0.76,0.78 and 0.57 respectively.
