四七論爭에서의「四端」解釋

This essay treats the theoretical disputes over '4 Dan-7 Jong' theory in 'Ri-ki' philosophy between Lee Toigye (1501∼1570) and Ki Ko-bong (1527∼1572) The controversy begun in 1559 and continued for 7 years, can be devided into 3 periods in its development in content, the first of which, the theoretical developments of the two philosophers, has been treated here in their mutual comparisive aspects. Ki Ko-bong refuted Toigye's theory, and Toigye on his side refuted Kobong's refutation supporting his own theory. I here support Toigye on this point on several grounds. I go on thereafter to present the following problems of importance. (1) the Being, defined as 'Thin' in general, is devided into real and ideal Beings. (2) Everything is derived from, and explained by 'Thing', to which is applied Ri-ki logic, the logic which is plane-level logic, unlike the one which goes through contradiction to unification. (3) The method of philosophy is regarded as the way to the progressive realization of Goodness through introspection; the way includes nothing of the conversion from quantity to quality, but only the quantative development. (4) The principle on which to define good and bad is, here, 'Ju-Ri' (Ri as the main role), or 'Ju-Ki' (Ki as the main role), the theory of mutual appearance of Ri and Ki. (5) The problem of the systemic order of values (goodness). The five problems above are very important in establishing Toigye philosophy on a newer and richer ground.

The autochthonous and allochthonous organic carbon loading were measured in Lake Soyang, to estimate the amount of carbon loading into the lake and the contribution of their sources to the lake's carbon loading. Autochthonous carbon loading was estimated from phytoplankton primary production with the extracellular organic carbon(EOC). Allochthonous loding was determined by measuring dissolved organic carbon(DOC) and particulate organic carbon(POC) concentration in the main inflowing Soyang River. Both autochthonous and allochthonous organic carbon loading were high during the summer, from July to September, and accounted for 43.2% and 71.7% of the annual loading, respectively. Primary productivity was elevated up to 1,000 mgCm^(-2)d^(-1)during summer and lowest in winter. EOC production from phytoplankton was also large in summer, resulting in a high DOC concentration in the lake water. Primary production of phytoplankton and allochthonous organic matter loading from the watershed contributed to 53.6% and 46.4% of total loading, respectively. The EOC production accounted for 4.4~21.2% of POC primary production, implying that EOC production of phytolankton must be considered in estimation of primary production.

AC4CH-based metal matrix composites with All_8B_40_33w reinforcement have been produced using squeeze casting method Metal matrix composite that is produced from matrix material AC4CH and inorganic binders Al_2O_3 and TiO_2 are added to the metal matrix composite for strength so binding among the whisker can take place. In this paper, an investigation was performed on frictional abrasion and the fracture toughness of AC4CH alloy reinforced with 20wt% aluminum borate whisker which contained a Al_20_3, TiO_2. The test of fracture toughness was using CT(half-size) specimen of thickness 12.5mm, width 25mm(ASTM E1820). To test for tribo a pin-on-disk machine and lubricant is used without paraffine 8.2CST at room temperature.

The influence of reactant gas composition on the rate of the water gas shift reaction over an iron oxide chromirum oxide catalyst was studied. This method of analyzing experimental tests showed that the rate of initial reaction of the water gas shift reac tion had increased with increasing P_(H_2O), but that had decreased with increasing P_(CO_2). It was found that the mass tranfer affect the rate of the water gas shift reaction except catalyst system. And this experimental results showed that the rate of reaction had increased with increasing P_(CO_2) and P_(H_2O). At this experimental condition, the rate of initial reaction was established γ_0=kP_(CO_2) P_(H_2O)/1+K_(H_2O) P_(H_2O) and the reaction rate constant, K, 225(m㏖/g-cat. hr) and K_(H_2O) is 3.5(atm)^-1.

The study was performed to observe the effects of arthrography on the tissues of temporomandibular joint histopathologically. Among 17 rabbits(34 joints), 2(4 joints) were used as normal control group, others (30 joints) were experimentally arthrographed using 0.03 ml diatrizoate meglumine (Hypaque meglumine 60, Wintrop, U.S.A). The rabbits were sacrificed at 2-hour, 1-, 2-, 4- and 7-day after experiment and the tissues of temporomandibular joint were prepared according to the usual method for light microscopic examination. The results were as follows: 1. There were no changes of the fibrous connective tissues of the condylar fossa, the fibrous connective tissues and hyaline cartilages of the condyle, and the articular disk. 2. In 2-hour experimental group, the proliferation of the surface synovial membrane cells, the congestion and hemorrage of the vessels were observed. 3. In 1 and 2-day experimental group, minimal lymphocytes infiltration was observed with the proliferation of the surface synovial membrane cells, the congestion and hemorrage of the vessels. 4. In 4-day experimental group, the diminution of the proliferation of the surface synovial membrane cells was seen, but there was no vascular changes. 5. In 7-day experimental group, the tissues showed similar appearance to the normal control group.

The modelling of complex dynamic system is one of the most important subjects in engineering. A model is often too complicated to be used in real problems so approximation procedures are often used to achieve simpler models than the original one. The concepts of impulse energy approximation is introduced. The reduced model in obtained from the most significant pairs of alpha and beta parameters. There exists errors because from the most significant pairs of alpha and beta parameters. There exists errors because of the truncation. To overcome this problem an improved impulse energy technique is presented in the paper by appropriately selection alpha and beta parameters. There exists error because of the truncation. To overcome this problem an improved impulse energy technique is presented in paper by appropriately selecting alpha and beta parameters to retain more impulse response of the original system. This algorithm is programed using MATLAB language. A reduced-order model for the excitation system of power plants as an example study is considered This technique seems to be easy to perform and shows a good simulation results.

The axial mixing characteristic were investigaved in a cocurrent bubblecolumn containing vertical rods. The gas hold-up was determined by the bed expansion measuring technique. An impulse response technique was employed to obtain RTD-curves. The RTD-curves were analysed for determination of the mean residence time and the axial disperson coefficient. The gas hold-up was not affected by the ncrease of the number of rods, but there were increasing tendencies of the mean residence time and the axial dipersion coefficient with the increase of she number of rods. Also axial dispersion coefficient was found to increase with superficial liquid and gas velocity. The data weve obtained in the approximate range of gas velocity of 3 ㎝/sec to 10 ㎝/sec and liquid velocity of 0.2 ㎝/sec to 0.9 ㎝/sec.
