균일 수용액과 polyacrylic acid(PAA) 존재하에서 3,3'-diethyl oxacarbocyanine(DOC)의 spectra변화를 흡수 및 형광분광학적인 방법으로 연구하였다. 균일 수용액에서 DOC의 농도변화에 따른 흡수 spectra변화는 dimer의 형성에 기인하는 것으로 설명하였다. PAA의 존재하에서 P/D변화에 의한 형광세기의 변화는 흡수 분광학적 방법과 유사한 결과를 얻었다. PAA와 DOC의 상호작용의 반응속도론적인 연구를 흡수 및 형광 정지흐름법으로 수행하였다. PAA-DOC계에서 관측된 이완효과는 두 개의 이완과정이 존재한다고 가정함으로써 정량적으로 설명할 수 있었다. The spectral changes of 3,3'-diethyl oxacarbocyanine(DOC) in the aqueous solution and in the presence of polyacrylic acid(PAA) were studied by means of absorption and fluorescence spectroscopy. The spectral change of DOC in the aqueous solution with concentration changes is attributed to the formation of dimer. In the presence of PAA, the characteristic changes of metachromatic band with changes of P/D (the ratio between available binding site and the dye concentration) are found and the discussions are made in terms of stacking theory. A kinetic study of the interaction between DOC and PAA was also investigated by the absorption and fluorescence stopped-flow spectroscopy. The observed relaxation effect in PAA-DOC system can be described quantitatively by assuming two relaxation processes occur.

3, 3'-Dipropyl oxacarbocyanine(DPC)와 poly(styrenesulfonate)(PSS)의 상호작용효과를 흡수 및 형광 분광학적 방법으로 연구하였으며, 이들 효과는 stacking model로 설명 되었다. DPC와 PSS 계의 상호작용에 대한 반응속도론적 고찰을 흡수 및 형광 정지흐름법에 의하여 연구하였다. DPP-PSS계의 이완효과는 두개의 이완과정을 가정함으로써 정량적으로 설명할 수 있었다. 또한 염효과에 의한 이완시간의 변화를 고찰하여 DPC-PSS계의 회합반응 메카니즘이 두 단계로 일어남을 설명할 수 있었다. The interaction between 3,3'-dipropyl oxacarbocyanine and poly(styrenesulfonate) has been studied by means of absorption and fluorescence spectroscopic methods. The results was interpreted by stacking model. The kinetic studies of the interaction between 3,3'-dipropyl oxacarbocyanine and poly(styrenesulfonate) were carried out by the absorption and fluorescence spectroscopic stopped-flow methods. The observed relaxation effect in DPC-PSS system was described quantitatively by assuming two relaxation processes. The dependence of rate of reaction on the salt concentration of the solution was also studied. The results are consistent with the two-step mechanism.

A clinicll observation on 62 cases of the pelvic bone fractures treated in the 77th Army Hospital from Jan. to Dec. 1967 is presented here. The results were as follows: 1. The pelvic bone fractures were 6.6% in all the fracture patient who were treated in this hospital through last year. 2. The cause of the pelvic bone fractures was all automo비Ie accident, Exclude 2 cases of explosive injury. 3. 51. 6% of the pelvic bone fractures were complicated by other bone fractures and soft tissue injuries. 4. The pubic rami fractures were the most common fractures of the pelvic bone, and bilateral pubic rami fractures were more common than unilateral pubic rami fractures. 5. There were the most complication in bilateral pubic rami fractures, rupture of the bladder and urethral injuries were 60.7% in bilateral pubic rami fractures. 6. Cases in inferior pubic rami fractures were complicated by urethral injuries.

For upland crops the returns from the investment in variety developmet and improvement are manifested through the increased production and superior quality of the crops grown from the new varieties. The varieties must be distributed widely, and rapidly, and sufficient seed or vegetatively propagated materials must be produced so that the varieties can be grown on the farms in the area in which it is adapted. The benefits from the improved varieties can be realized through growing the certified seed with sufficient genetic identity, purity and plumpness. Of the upland crops including wheat and barley, soybeans and other legumes, minor cereals and root and tuber crops, currently important crops were evaluated for the current situation and problems of seed renewing systems, and for the status of the crop production and demand and supply to find out practical problems in seed production. Solutions to the problems have generally been found from the investigation and long experience. For increased production and grain quality improvement of malting barley and rye, seed renewing programs should be strengthened in the near future. Certified seed supply and shortening of good quality seed renewing-year interval must be made through improvement of varietal and regional seed renewing systems. Particularly, for emergent need of wheat seed, foundation seed storing system must be established. In, soybeans six-year interval renewing system would be desirable in practice and should be fully practiced. Soybean seed production has been conducted by the Farmer’s Corporation Agency in accordance with increased soybean production assistance plan. However, certified seed production system and good quality seed production techniques must be applied desirably. Government-leading purchase price for the soybeans produced by farmers must be increased for farmers’ willingness to produce more soybeans. For corn sufficient amount of certified seed must be produced because a quantity of corn seed has been imported to meet the demand. In 1990, estimated amount of corn seed 1,500 to 2,000 M/T would be needed for silage and grain corn production. Past experience of suplus corn seed suggests that low temperature seed storage facility is to be facilitated for safe storage of high quality of corn seed.

Nature of gene action and inheritance of the days to flower in mungbean (Vigna γ-adiata (L.) Wilczek) were determined in the F₁ and F₂ generations of 30 possible combinations of six-parent diallel cross. All the F₁ populations were grown in the pots(1/5,000a) under three different day length conditions (natural, 9-hour and 16-hour photoperiods). The F₂ populations were grown under two different plantings, early and late, in the experimental field of Crop Experiment Station, Suweon, Korea in 1984. The analysis of degree of dominance on the days to flower showed partial-to over-dominance, but the direction of dominance varied with different cross combinations. Early flowering in F₁ generation appeared to over-dominance over the late flowering under 9-hour photoperiod with no general tendency under natural and 16-hour photoperiod. Combining ability analysis indicated that both additive and non-additive gene action were involved in the days to flower. The estimation of broad sense heritability was considerably high for the days to flower (78.3%). The heritability estimates and F₂ distribution suggested that the photo-sensitive factor of V1094, which is photo-insensitive genotype was not expressed due to recessive inhibitor factor.

The combination of early heading time and short grain-filling period is very important to develop early varieties in winter barley. Parents, F₁, F₂ and back-cross generations of four crosses were grown in the controlled greenhouse and field to partition genetic components and evaluate the selection efficiency. The earliness of heading time was due to a few partial dominant and minor genes in two crosses, but the crosses with Tokak showed the transgressive segregation with predominantly early heading individuals in the greenhouse. The grain-filling period was controlled by a few partial dominant or dominant, and minor genes in the greenhouse. The realized heritability estimates for heading time and grain-filling period, depending on the crosses, ranged from 59 to 86% and from 47 to 89% in the field, respectively. The high heritabilities and considerable genetic gains indicated that the selection for two short periods in the early generations might be very effective.
