Sasang Constitutional Medicine focuses on the different constitutional manifestations of the individual's nature and emotions. The nature and emotions drive the ascending and descending of Qi in the body. And this dynamics of the Qi's ascent and descent shapes the different types of structures, functions and temperaments. Although Sasang Constitutional Medicine has many advantages, its diagnosis of the constitution still depends on the doctors' own idea and has no objective identification. So many doctors in Korea have been trying to solve this problem. Recently, there are several efforts to find out the relationship between genetic information and constitution. By the way, May, 1998 there is a astonishing report about the gene which determines the human performance, that is ACE(angiotensin converting enzyme). And it suggests that the I allele was associated with improved endurance performance. ACE has three genotype including II, ID and DD. "I" means insertion and "D" means deletion. We determined the type of the Sasang constitution with QSCCII questionaire and the one's ACE genotype with PCR of the 127 people and we discovered the relationship between the constitution and the ACE genotype. The result is as follow. Among 39 people who have the II genotype, 7(18%) belong to Taeum(Taiyin), 9(23.1%) belong to Soyang(Shaoyang) and 23(59%) belong to Soeum(Shaoyin). Among 62 people who have the ID genotype, 18(29%) belong to Taeum(Taiyin), 21(33.9%) belong to Soyang(Shaoyang) and 23(37.1%) belong to Soeum(Shaoyin). Among 26 people who have DD genotype, 11(42.3%) belong to Taeum(Taiyin), 4(15.4%) belong to Soyang(Shaoyang) and 11(42.3%) belong to Soeum(Shaoyin). This data indicates that there are implicable relationship between the Sasang constitution and ACE genotype. Especially people who have II genotype have much possibility to be a Soeum(Shaoyin) person (59%) and Soyang(Shaoyang) person have less possibility to have DD genotype (15.4%). With this conclusion, we suggest further study of relationship between the Sasang constitution and ACE genotype and we think that other polymorphism can be a candidate of the partner of Sasang constitution.

An experimental study is performed to evaluate the performance and the efficiency by humidifying MEA and by making the double-tied catalyst layers in a fuel cell system which is taken into account the physical and thermal concept. An electrical output produced by PEFC(Polymer Electrolyte Fuel Cell) is measured to assess the performance of the stack and the efficiency is also evaluated according to the different situation in which is placed with and without the humidification of MEA(Membrane Electrolyte Assembly). Subsequently, It is found that the measured values of stack voltage and current are influenced by the stack temperature, humidification, and the double-tied catalyst layers which gives more enhanced values to apply for electric units.

허문회,조윤희,김홍열 서울大學校 農科大學 1985 서울대농학연구지 Vol.10 No.1

ms-WA에 由來하는 導入CGMS系統에 韓國育成系統을 數回 Backcross하여 CGMS를 置換한 不稔系統을 育成하고, 이들과 導入不稔系統에 대해 높은 稔性回復을 보여 준 國內 育成系統인 稔性回復親을 交配하여 그 雜種들의 生産性을 3가지 相異한 件 下에서 栽培檢討하였다. 그 結果는 다음과 같다. 1. 育成不稔系統들의 維持親은 導入不稔系統들의 維持親에 比하여 平均 48%나 多收인데도 不拘하고 몇 가지 韓國育成品種을 稔性回復親으로 하여 雜種을 만들었을 경우, 育成不稔系統과의 雜種을 導入不稔系統과의 雜種에 比하여 平均 26%나 收量이 낮았다. 同一郡內에 있어서도 組合에 따라 顯著한 差가 있었다. 2. 收量構成形質別로는 導入不稔系統들은 當粒數와 千粒重이 크고 育成不稔系統들은 이들이 낮았으며, 稔性回復系統들은 大體로 이들의 中間이었다. 3. 不稔維持系統의 雜種生産性과 不稔系統의 雜種生産性과의 相關은 顯著하지 못하여 維持系統의 雜種生産性으로 不稔系統의 雜種生産性을 推定하기에는 不充分하였다. 4. Heterobeltiosis로 表示한 雜種强勢는 導入系統들이 顯著하게 높았고 育成系統들에서 낮았으며, 同一郡內에서도 系統에 따라 다르게 나타난다. 5. 導入不稔系統들은 當粒數와 千粒重의 雜種强勢가 크고 育成系統들은 數와 稔實率의 雜種强勢가 크게 나타났다. 6. 不稔系統의 雜種强勢와 維持系統의 雜種强勢와의 相關은 中 程度이었으며, 이러한 傾向은 導入系統에서나 育成系統에서 비슷하다. 7. 導入系統들은 GCA가 높고 SCA가 낮은데 比하여 育成系統들은 GCA가 매우 낮고 SCA는 中 程度이었으며 稔性回復親들은 GCA는 中 程度, SCA는 매우 높았다. 8. "收量이 많은 系統들은 自植收量이 낮고, GCA가 極度로 높으며 SCA와는 相關이 없고 heterobeltiosis가 매우 높은 系統"이라고 말할 수 있는데, 이런 結果가 普遍化 될 수 있는가는 앞으로 더 檢討되어야 할 것이다. Cytoplasmic-Genetic-Male-Sterile (CGMS) lines were bred through backcrosses of ms-Wa derived from foreign CGMS limes to the Korean cultivars. Both the MS and their maintainer lunes of the introduced and the bred were crossed with identified fertility restorer (Rf) lines and their F1 productivity was tested under 3 different environments. The results are summarized as follows: 1. When the Korean cultivars were used as fertility restorer (Rf) the hybrid yield of newly bred CGMS lines was 725.8 kg/ha and those of introduced ones was 844..5 kg/ha in average. The yield of their maintainers were, in average, 558.7 kg/ha and 377.2 kg/ha, respectively. Yield differences among lines within a group of lines were significant. 2. Among the yield component agronomical characters, the number of spikelets per panicle and 1000grain weight contributed significantly to the hybrid yield of introduced ms lines, while those of bred ms lines were not significant and those of Rf lines were in between of them. 3. The correlation between the ms lines hybrid productivity and their maintainer's hybrid productivity was not significant and the correlation coefficient for the hybrid productivity of Chinese ms lines and their maintainers was even lower. This might imply that it is difficult to predict the hybrid productivity of the breeding ms lines with that of the recurrent parent to be used in the backcrosses to introduce the foreign CGMS into the leading Korean cultivars. 4. The hybrid vigor of yield, expressed in terms of Heterobeltiosis, was greater in the hybrids with introduced CGMS lines than the hybrids with breeding lines which are more closely related to the Rf parents, and it was widely variable depending upon the lines and environments. 5. The heterobeltiosis of the introduced CGMS lines were more prominent in the spikelets per panicle and 1000grain weight but the heterobeltiosis of the bred lines were distinct in the number of panicles and % of fertility. 6. The correlation between the yield heterosis of CGMS lines and those of their maintainer lines hybrids was not significant and the trends were same in both of the bred and introduced. 7. The introduced lines showed high GCA and low SCA, while the bred lines showed very low GCA and medium SCA. But, the Rf lines showed medium GCA and very gifh SCA. 8. In this experiment, the highly productive CGMS lines showed rather lower productivity of their maintainer line, extremely high GCA, not significant correlation with SCA and very high yield heterobeltiosis. These results should be conformed through the extended breeding materials.

水稻 品種間 交雜에 있어서 稈長의 遺傳 分離 : Ⅷ. 短稈 Japonica 品種들과 d-t 對應 長稈 檢定親과의 組合 Ⅷ. The segregation of culm length in the crosses between short Japonica cultivars and a tall Indica tester allelic to d-t height.

短稈 Japonica 品種들의 Semi-dwarf (d-t) gene에 對한 allelism을 檢討하기 위하여 Semi dwarf gene을 가진 wx 817과 그에 대하여 allelic tall 因子를 가진 Binato를 檢定親으로 하여 Binato에 6個의 短稈 Japonica 品種을 交配하여 그 F₁, F₂ 및 F₃를 展開하여 稈長을 調査하였다. 그 結果를 要約하면 다음과 같다. 1. 檢定親稈 組合인 Binato×wx 817의 F₂에서는 長稈:短稈이 3:1로 分離되어 기왕의 報告와 一致하였다. 2. 供試된 短稈 Japonica 品種들은 檢定親인 Binato와의 組合 F₂에서 年次間 變異에 關係없이 모든 組合에서 長稈:短稈이 3:1로 分離되었다. 3. 短稈群에서 選拔된 F₃系統은 選拔 當時의 稈長을 中心으로 正規分布를 나타냈으나, 長稈群에서 選拔된 系統은 分離하는 것과 그렇지 않은 것이 2:1로 分離되어 理論値에 適合하였다. 4. 組合에 따라서는 F₃系統의 稈長 變異의 幅이 F₂集團에 비하여 다소 短稈된 組合과 伸張된 組合이 있었으나 稈長의 分離 樣相은 모든 組合에서 同一하였다. 5. 以上의 結果로 보아 供試된 短稈 Japonica 品種들의 稈長을 支配하는 主??遺傳子는 同一하지만 組合에 따라 서로 다른 微??遺傳子가 存在하는 것으로 推定된다. 6.F₂長桿群에서 選拔한 2群, 長一長群과 長一短群은 F₃에서 분명히 差가 나는 mode를 나타내어 選拔의 를 할 수 있었다. F₂短桿群에서 選拔한 F₃個體들의 變異를 보아 短稈群에서의 選拔도 有意할 것으로 추축되었다. Investigations were made to search for the semi-dwarf Japonicas allelic to the semi-dwarf rice cultivars which is controlled by d-t gene. Six dwarf Japonicas, Reimei,Hoyoku,Shiranui,Kokumasari, M.7 and S.224 were crossed to the tall tester cultivar, Binato. Binato is known having tall allelic gene to semi-dwarf gene d-t. Their F₁, F₂, and F₃ were grown in 1984 and 1985 and culm length were measured at harvest. The results are summarized as follows: 1. In the F₂ of test cross, Binato/wx817, culm ength was segregated 3 tall to 1 short, which conformed the tester's validity. 2. The F₂s of all 6 crosses showed 3 tall to 1 short segregation which indicated the short Japonicas were allelic to the tall tester variety. 3. F₃lines selected from short group of F₂showed no segregation but F₃ lines selected from tall group of F₂ were segregated in to 2 segregating and 1 not-segregating. 4. The range of variation of the short segregants and the tall segregants were variable depending on the cross combination, but the general patterns were similar in all 6 crosses. 5. From the results of F₂and F₃ segregations, it was concluded that the 6 semi-dwarf Japonicas tested here were controlled by same major gene d-t though they were modified by different minor genes. 6. The modes of segregation in F₃s selected from taller tall and selected from shorter tall were significantly different in every crosses which implies the selection effects. The selection effects in the short group also was presumed from their wide variations in F₃.

The discrepancies between theoretical values and measured data of PEFC(Proton Exchange Fuel Cell) is carried out for the machine tool power generation. Rudimental approach of theoretical fuel cell open circuit potential using Gibbs free energy is employed for the examination of PEFC module. The stack temperature, stack voltage and stack current are measured during the operation of PEFC module. It is found that stack voltage and current values show the pronounced discrepancy with the results calculated by Gibbs free energy approach. It is analysed that the discrepancy is due to activation polarization, concentration overvoltage and ohmic overvoltage.

PEMFC (Proton Exchange Membrane Fuel Cell) is considered as an attractive option to produce electric power in many applications. A fundamental step of theoretical fuel cell open circuit potential is examined and compared with the measured data from 1.2KW PEMFC module. The hydrogen pressure and stack temperature are also measured during the operation of PEMFC module. It is found that the stack voltage and current data agree in general with the results calculated by chemical potential approach though they still have a discrepancy. It is analysed that the discrepancy is due to activation polarization, concentration overvoltage and ohmic overvoltage.
