  • The purpose of this study is to investigate the effect of dietary fiber content of rice on the postprandial serum glucose and insulin responses in normal subject. Two rice varieties, Ilpum and Suwon 464 which are different in dietary fiber content, were cooked in pressure cooker and used for the test. The rice with a higher dietary fiber content gave a significantly lower glucose level (p<0.01) and insulin level (p<0.05) than did the normal rice variety. After a meal, the 60-min glucose levels of Suwon 464 and Ilpum were 90.3${\pm}$4.8mg/dl and 111.6${\pm}$2.7mg/dl, respectively. The glycemic index (GI) of Suwon 464 shows 64.5%, which was apparently lower than that of Ilpum. These results indicate that Suwon 464 high in dietary fiber can be useful in low-GI diets.

  • Purpose: A study was designed to compare heart rate variability (HVR) of older adults with postprandial hypotension (PPH) with older adults with no PPH. Methods: The samples were community-dwelling older adults (${\geq}$ 60 years old) with PPH (n=35) and without PPH (n=35). HRV was measured by 10 minutes of electrocardiography using Physiolab 400 and analyzed in time domain (SDNN) and with power spectral analysis in frequency domain (TP, LF, HF, LF/HF). Blood pressure was measured every 15 minutes before and until 120 minutes after the meal. Results: All HRV parameters were lower in the PPH group compared to those with no PPH. Specifically the measures of SDNN, TP, LF, and LF/HF of the PPH group were significantly lower (U=385.0, $p$=.008; U=361.0, $p$=.003; U=375.0, $p$=.005; U=368.0, $p$=.004, respectively). Further, the LF and LF/HF of SBP (${\geq}140$ mmHg) group and the LF/HF of DBP (${\geq}$ 90 mmHg) group were significantly lower ($x^2$=6.33, $p$=.042; $x^2$=33.10, $p$ <.001; $x^2$=11.03, $p$=.004, respectively). Conclusion: These findings indicate that the autonomic nervous functions in persons with PPH are less activated than those persons with no PPH. The findings contribute to an understanding of HRV and the association of autonomic nervous function with the mechanism of PPH.

  • To investigate the effect of cooking form of rice and barley on postprandial serum glucose and insulin response in normal subject, five test carbohydrates calculated to contain 50g of glucose were consumed. Oral ingestions were divided into 5 group, i. e. dextrose(control), ground white rice, ground barley, whole white rice, whole barley, Postprandial glucose and insulin responses were measured over 3hr and showed the following pattern. Dextrose and ground white rice elicited similar postprandial serum glucose and insulin responses whereas ground barley and whole white rice intemediate, whole barley gave the lowest responses in the test group. The ground form of rice and barley were significantly higher responses than the unground form of those as well as whole white rice were higher responses whole barley, The results suggested that the cooking form of rice and barley was an important determinant of the postprandial metabolic responses.

  • Experimental trials of unilateral lung transplantation in dogs have been attempted and satisfactory results were obtained without any noticeable difficulty in surgical techniques. Fourteen dogs with the body weight of around 25 kg were anesthesized by 20~30 mg/kg of intravenous Entobar,; one was sacrificed to make available blood for use during transplantation for the recipient dog. A mid-sternotomy incision was performed and 20 mg/kg of Prostaglandin E1 was infused through the pulmonary artery and Euro-Collin's(E-C) preservation solution, cooled down to 4$^{\circ}C$, was perfused at the rate of 70cc/kg by a pressure of 30 cmH2O. The heart-lung block was then resected out and promptly immersed in the prepared preservation solution at 4$^{\circ}C$. One lung preserved in the EC solution at 4$^{\circ}C$ was anastomosed to the recipient dog in the order of the pulmonary vein, bronchus then pulmomary artery and the thoracotomy incision was closed after the bleeding control and tube thoracostomy. Then the pneumonectomy in the opposite side was perfomed in the same manner and the tailored lung was transplanted in the order of the pulmonary vein, bronchus, then pulmonary artery. We conclude that in the bilateral sequential lung transplantation, the right lung transplantation should precede to better expose the operative field and to prevent reperfusion injury; also, the cardiopulmonary bypass should be consider for certain appropriate cases.

  • A study was carried out to examine the effect of water temperature on daily pattern and rate of total ammonia nitrogen (TAN) excretion in juvenile Pacific cod Gadus macrocephalus (mean body weight: $36.5{\pm}0.8\;g$) under fasting and feeding conditions. Fish were acclimated over 10 days under three different water temperatures (9, 11 and $13^{\circ}C$), and transferred to TAN measuring system under each water-temperature condition. After 72 hours of starving, fasting TAN excretion was measured at each temperature. To investigate post-prandial TAN excretion, fish were hand-fed with a commercial diet containing 40.6% crude protein for 7 days, two times daily at 08:00 and 16:00 h. Water was sampled from both the inlet and outlet of the fish chamber every 2 h over a 24-h period. Both fasting and post-prandial TAN excretion increased with increased water temperatures (p<0.05). Mean fasting TAN excretion rates at 9, 11 and $13^{\circ}C$ were 9.3, 11.0 and $11.9\;mg\;TAN\;kg\;fish^{-1}\;h^{-1}$, respectively. The value of $9^{\circ}C$ was lower than those of 11 and $13^{\circ}C$ (p<0.05), but there was no significant difference between $11^{\circ}C$ and $13^{\circ}C$. Mean post-prandial TAN excretion rates at 9, 11 and $13^{\circ}C$ were 23.0, 31.6 and $45.4\;mg\;TAN\;kg\;fish^{-1}\;h^{-1}$, respectively. A peak value of post-prandial TAN excretion rate occurred after 2 h from each feeding, and the second value is always higher than the first value. Maximum post-prandial TAN excretion rate occurred after 10 h from the first feeding at $9^{\circ}C$ (mean $38.0\;mg\;TAN\;kg\;fish^{-1}\;h^{-1}$), $11^{\circ}C$ ($52.9\;mg\;TAN\;kg\;fish^{-1}\;h^{-1}$) and $13^{\circ}C$ ($77.5\;mg\;TAN\;kg\;fish^{-1}\;h^{-1}$), respectively. The TAN loss for ingested nitrogen at $9^{\circ}C$ (43.9%) was lower than those of $11^{\circ}C$ (46.4%) and $13^{\circ}C$ (48.4%). The overall results indicate that water temperature exhibits a significant effect on the nitrogen excretion of juvenile Pacific cod.

  • The purpose of this study was to observe the effects of fiber free control diet (CD), cellulose diet (CED) and pectin diet (PTD) on diet induced thermogenesis (DIT) in healthy Korean woman for 3 hours. The three test diets were as follows: CD (carbohydrate intake: 63.4% of energy, protein intake: 14.0% of energy and fat intake: 25.8% of energy), CED (carbohydrate intake: 62.5% of energy, protein intake: 14.0% of energy and fat intake: 26.1% of energy) and PTD (carbohydrate intake: 62.7% of energy, protein intake: 14.0% of energy and fat intake: 26.2 of energy). Groups were served 10 g of cellulose for CED and 10 g of pectin for PTD, respectively. DIT was measured at fasting state and at 30, 60, 90, 120, 150 and 180 min after consuming each diet. The mean age of all subjects was $22.3{\pm}1.9$ years. Body weight was $52.5{\pm}8.6$ kg and body mass index was $20.6{\pm}2.7kg/m^2$. Preprandial resting energy expenditure was $0.79{\pm}0.02kcal/min$ and postprandial DIT were $14.05{\pm}0.62%$ for CD, $9.33{\pm}0.62%$ for CED, $11.07{\pm}1.35%$ for PTD as a percentage of the energy load. DIT of CD was significantly higher than those of CED and PTD. There was no significant difference in postprandial change in body temperature after consuming each test diets and the sympathetic nervous system activity measured by heart rate was significantly higher in CD than CED and PTD (p<0.05). With this study, it can be concluded that CED and PTD have significantly lowered in DIT (p<0.05). We didn't show the correlation of the factors that relate in DIT; thus, further experiments on that matter should be followed.

  • The effect of water temperature on fasting and post-prandial total ammonia excretion (TAN) of the starry flounder Platichthys stellatus (mean body weigh : $42.4{\pm}3.4g$) was studied. The fasting and post-prandial TAN excretions were measured under three different water temperatures (10, 15 and $20^{\circ}C$) for 24 hours using a recirculating system. In each treatment three replicates were set up and total 45 fish were used. Fish were taken to the indoor aquarium, acclimated over 10 days at three temperatures, and transferred to TAN measuring system for measurements of TAN excretion at the same temperatures. After 3 days of starvation, fasting TAN excretion was measured at each temperature. To investigate post-prandial TAN excretion, fish were hand-fed to satiation level with a commercial diet containing 50.2% crude protein for 7 days, two times daily 08 : 00 and 16 : 00 h. The fasting and postprandial TAN excretion increased with increased water temperature (p<0.05). Mean fasting TAN excretion rates at 10, 15 and $20^{\circ}C$ were 10.9, 11.2 and $12.2mg\;TAN\;kg\;fish^{-1}\;h^{-1}$, respectively. The value at $20^{\circ}C$ was higher than those at 10 and $15^{\circ}C$ (p<0.05), but there was no significant difference between $10^{\circ}C$ and $15^{\circ}C$. Mean post-prandial TAN excretion rates at 10, 15 and $20^{\circ}C$ were 33.0, 43.4 and $55.3mg\;TAN\;kg\;fish^{-1}\;h^{-1}$, respectively. Two peaks of post-prandial TAN excretions were observed, and the second peak was always greater than the first. The post-prandial TAN excretion rate reached to the maximum after 10 hours from the first feeding at $10^{\circ}C$($45.3mg\;TAN\;kg\;fish^{-1}\;h^{-1}$), $15^{\circ}C$ ($64.5mg\;TAN\;kg\;fish^{-1}\;h^{-1}$) and $20^{\circ}C$ ($83.2mg\;TAN\;kg\;fish^{-1}\;h^{-1}$), respectively. The TAN loss for ingested nitrogen at $20^{\circ}C$ (48.8%) was higher than that for $10^{\circ}C$ (43.0%) and $15^{\circ}C$ (45.7%). This study provides empirical data for estimating ammonia excretion and managing culture management of starry flounder under given temperatures.

Procedural Changes of Zhuzi(朱子)'s Theory of ZhongHe(中和) and the Theory of Jing(敬) (주자(朱子)의 중화설(中和說) 변천과정과 '경(敬)'공부론(工夫論))

  • In this paper, the writer examined the procedural changes of Zhuzi(朱子)'s theory of ZhongHe(中和), and also investigated the evaluations thereof made by the later generations. In the stage of ZhongHeJiuShuo(中和舊說), Zhuzi(朱子) ignored the theory of Lidong(李?), which was traditional theory argued by DaoNam School(道南學派). He met Zhangshi(張?) of HuXiang School(湖湘學派) and followed the school's philosophy, 'XianChaShiHouHanYang(先察識後涵養)', meaning what you should do first prior to making great efforts in self-cultivation is to examine the past, when desiring to know yourself. Even though Zhuzi(朱子) had learned the method of moral cultivation from Lidong(李?), he was fascinated by such method of moral cultivation as 'XianChaShiHouHanYang(先察識後涵養)' advocated by HuXiang School(湖湘學派) through discussion with Zhangshi(張?). This tells that he only recognized the fact that there were no achievements WeiFa(未發), but only the achievements YiFa(已發). In the stage of ZhongHeXinShuo(中和新說), he realized the mistakes committed in the time of ZhongHeJiuShuo(中和舊說), and put emphasis upon the achievements in the time WeiFa(未發). Zhuzi(朱子) had explained the relationships among mind, nature, and emotional bond as by his theory, 'XinTongXingQing(心統性情)', meaning that mind controls humans' original nature. Also he followed self-cultivation of Respect, no longer believing the Huhong(胡宏)'s XianChaShiHouHanYang(先察識後涵養). Such a method of self-cultivation means that his method of moral cultivation centered on the achievements YiFa(已發), which was originated from HuXiang School(湖湘學派), had been changed into the method of moral cultivation with a focus on the achievements WeiFa(未發), which was theory argued by DaoNam School(道南學派). However, Zhuzi(朱子)'s theory of ZhongHe(中和) that had seemed perfect began to be discussed and polished again during Joseon Period through the debates between Ligu(栗谷) and Niuxi(牛溪) in the 16th century, and through the debates between Youan(尤庵) and Yuxuan(寓軒) in the 17th century, also through the HuLuoLunZheng(湖洛論爭) represented by Nantang(南塘) and Weiyan(巍巖). Since Zhuzi(朱子)'s theory of ZhongHe(中和) had some flaws, it had to put through such debates as mentioned above. Those debates were generated because imperfections were found in the theory of ZhongHe(中和) by Zhuzi(朱子).
