Fifty-one kinds of confections in the market were selected for study. The pH of samples was measured by Bechman φ40 pH meter using the 10ml mixture of 1 gm sample, 2ml saliva, and distilled water. The buffering capacity was measured by titrating the 10ml mixture of 1 gm sample and distilled water by 0.1 N lactic acid to the point of pH 3.00. The buffering capacity in saliva was measured by titrating the 10ml mixture of 1 gm sample, 2ml saliva, and distilled water by same method. The pH drop during fermentation was measured at first and fourth hour during fermentation using the 10ml mixture of 1 gm sample, 2ml saliva and distilled water incubated at 37℃. The acid-producing capacity was measured by titrating the 10ml mixture incubated for four hours by 0.IN NaOH to the point of original pH. 1. The pH was 6.98±0.87, and the pH in saliva was 7.09±0.61. 2. The buffering capacity was 287±710 μl, and the buffering in saliva was 195 ± 76μl. 3. The pH after one hour of incubation was 7.08±0.39, the pH after four hours of incubation was 4.88±0.52, and the acid-producing capacity was 191±77μl. 4. The pH, pH in saliva, buffering capacity, buffering capacity in saliva, pH dropfter one hour of incubation, and pH drop after four hours of incubation were showed statistically significant relationship each other in Spearman's rank correlation (p < 0.05), but the acid-producing capacity did not show any statistically significant relationship with others except the pH drop after four hours of incubation. 5. The oral health professionals, consumers, and manufacturers should cooperate in developing the confections with higher pH, greater buffering capacity and lesser acidproducing capacity.

We added complex functional ingredients that were derived from the fermented product of Ang-Khak into a well-nutritive soybean curd in order to evaluate the function of Ang-Khak and soybean efficiently. In the production process of red soybean curd(RS) according to Ang-Khak concentration, as we compared it with a common soybean curd(CS), there were no obvious differences in the composition and yield. In the color, L- value tended to be reduced, in order of CS>RS1>RS2> RS3>RS4>RS5, as additional concentration of red rice extract increased(P<0.05). a-value tended to be the opposite way of the L-value, in order of RS5>RS4>RS3>RS2>RS1>CS(P<0.05) and b-value appeared lower than CS value overall(P<0.05). The properties of the red soybean curd's texture showed the differences in only hardness and adhesiveness(P<0.05), not in cohesiveness, springiness and gumminess. In overall sensory evaluation, the color of RS appeared red(P<0.05) and the odor(roasty) and texture(hardness) had no differences. RS was almost same value as CS in the taste, but was not as favor as much than CS in overall preference(P<0.05).

The human proteomics-based approaches, which examine the expressed proteins of a tissue or cell type, are increasingly being used. Venous occlusion is commonly employed for stimulating tissue-plasminogen activator (t-PA) and plasminogen activator inhibitor-1 (PAI-l) release from venous endothelial cells, and this has been regarded as a parameter of the individual fibrinolytic capacity of plasma. The present work involved a detailed investigation of the plasma proteome and fibrinolytic activity in normal subjects, with the aim of determining whether correlations exist between various parameters of the fibhnolytic system before and after venous occlusion. We analyzed fibhnolytic parameters and plasma proteome before and after 15-min periods of venous occlusion in the forearm in 10 healthy 3rd-decade volunteers. Proteome analysis was performed using two-dimensional gels. The tryptic digests of some proteins were confirmed by MALDI-TOF and the MS-Fit algorithm. The fibrinolytic response as measured by the absolute amount of t-PA after venous occlusion was increased by venous occlusion (5.5 vs 9.6 ng/㎗, p<0.05), as was PAI-l (46.8 vs 56.1 ng/㎗, p<0.05). However, two-dimensional electrophoresis finding was virtually nonspecific and inconsistent after venous occlusion in healthy male subjects. Venous occlusion does not influence plasma proteome in healthy males. Although the fibhnolytic response to venous occlusion is attributed to an increase in free tUPA antigen, this change is not correlated with plasma proteome.

In order to estimate DOA(Direction Of Arrival) of signal, the adaptive beam forming algorithm based on MUSIC(Multiple Signal Classification) is studied and analyzed. The eigenvalues for the signal component and the noise component are obtained from correlation matrix of the received signal by array antenna. The eigenvalues classified the signal components into the noise components decide the power spectrum of the received signal. From the results, DOA is estimated by the signal and noise spatial vector, and the steering beam pattern is found by weight vectors calculated from the spatial vector, effectively.

The basic ideas of the new community movement were based on the autonomous and voluntary participation of local residents. Since the beginning of the Saemaul Undong in the early 1970, Korean government has been played a major role in igniting and pushing ahead with the new community movement. From intellectual, economic, social, cultural points of view, the new community movement with strong administrative guidlines has attained a lot of achievements during the past 10 years. What is more important, the voluntary participation of local people rather than the administrative directions are urgently needed to activate the rich and affluent villages in the new community movement of the '80. The directions of the desirable administrative guildines in the eighties are as follows; o To convert the directive points into the assistant one in planning functions of local development. o To formulate the group cooperation system in the decision making of local people. o To develop the inventive and suggestive systems of local residents on the new community movement. o To improve the understanding of the mass to make both the national and local development planning together. o To make a suggestion and publish the blue-print of long time development planning.

Mathematicians always try new pursuance for new discoveries and are willing to prove the discovered truth, for the written mathematics already known to us displays a very little portion on the sea level and the fact to be sought as well as its proof remains still unknown under the sea level. Therefore, the mathematics in the secondary school education emphasizes the proofs through the in-class mathematics, however only reveal the proofs made use of already-known proofs. The mathematical activities for creative thoughts are seldom to be found in reality. The purpose of this paper is to classify the formal types of the proofs to be proved, to introduce the meaning together with the formality of the proofs for each type, to obtain an idea for the proofs, and to seek and explore methods of the proofs guaranteeing the certainty by logical developments. For the methods of exploration of proof, this paper considered the understanding the theorem. recollection of the already learning proofs. forward and backward processes. The cultivation of the though power was emphasized through the analysis of the proofs in order to develop improved learning after proof learning.

This study is carried out to investigate the water quality changes in Busan Metropolitan streams. The results are as follows. In Busan Metropolitan streams, the loading rates of contaminants are greater in industrial waste water streams than domestic waste water streams. Some sampling points show a little high loading in autumn, but this needs more investigation to make clear the causes. The level of organic contaminants(BOD_(5) and COD_(MN)) is found to be low and does not show seasonal variation in domestic waste water streams. But, the level of organic contaminants in industrial waste water streams is relatively high and seems to be seasonally variable, which is affected by other factors. The nutrient materials, such as nitrogen(as T-N, about 20mg/L) and phosphorus(as T-P, about 2.0mg/L), are abundant than Nak Dong River and the general trends of contaminants level are similar to those of organic contaminants.
