This study aims to identify the characteristics of the cancelled districts of housing redevelopment and housing reconstruction project. The subject of this study is 189 project districts(121 promoted districts, 68 cancelled districts). Both 121 promoted districts and 68 cancelled districts were analyzed by Decision Tree Analysis. The first separation of the release zone influencing factors was made by the Development Actors. In other words, the most important independent variable for determining the release zone influence factor was shown to be the presence or absence of propulsion actors. Of the 89 districts without propellers, 41 were lifted and 48 were promoted, and 9 out of 100 districts with propellers were lifted and 91 were promoted. The second separation of the impact factors on the zone was then made by Land Owners, and the probability of cancellation increased if the number of landowners was less than 468 and 37 out of 62 were removed. On the other hand, four out of 27 districts with more than 468 landowners were lifted and 23 districts were promoted. The third separation was made by the Average Land Assessment, and 35 zones were lifted below the standard of KRW 269.64 million/m² approximately KRW 8.91 million per pyeong, and two zones were lifted at higher official prices. In the second division, the number of landowners was 468 or more, and in node4, four areas were removed from areas with a public land area ratio of 29.43% or more, and no areas less were released. This study used SPSS Statistics 26 S/W for analysis.

In order to examine the effect of 'Streptococcus lactis' inoculation on the maturation of cured ham, physicochemical changes in brine solution with and without inoculation were compared during period. The pH value of the curing solution in the inoculated sample were slightly higher than those in uninoculated one after 7 days of curing. The color development of cured meat was accelerated by the inoculation of the isolates as showing a 80% of color development within 7 days of curing. Among the 17 amino acids determined from the water protein, glutamic acid, valine and leucine were higher in the inoculated meat than those in uninoculated meat at the 7 and 10 days of curing. The oleic acid content was the highest among the 13 fatty acids detected from the all samples, and the content of oleic acid and total unsaturated fatty acids in inoculated samples were slightly higher than those in uninoculated samples.

This study was conducted to determine the influence of various extracts from 21 medicinal plants including Bupleurm falcatum on the germination and growth of Lactuca sativa, Oryza native and E. crus-galli var. crus-galli, and the amount of their phenolic acids, fatty acids and organic acids, Water extract(5%) of all the medicinal plants, particularly Acorus gramineus, Cnidium officinale, Aconitum carmicheali, Bulpeurum falcatum, Zingiber officinale, Angelica gigas and Curcuma zeodaria inhibited over 90% of the lettuce seed germination and growth, indicating that medicinal plants contained the biologically active substances. The highest amount of phenolic compounds was observed in Prunus crmenica var, ansu(30.6013mg/g) followed by Aconitum ciliare(29.1008mg/g) and Cnidium officienale(27.2943mg/g) which inhibited markedly the germination of testing plants, showing the close relation of phenolic compounds to inhibitory effects. Cnidium officinale contained the highest amount of fatty acids(24.10mg/g) and organic acids(21.04mg/g) which may be partly related to inhibitory effects.

F. roseum "Graminearum" and F. moniliforme were isolated from hulls of seeds collected from fields. F. roseum "Graminearum" was isolated from brown rice of all the varieties tested. F. moniliforme was isolated from Nagdongbyeo, Seomjinbyeo, Sinsunchalbyeo, Milyang 23, Baegyangbyeo and Samnambyeo. F. moniliforme was isolated from the most of the seeds damaged by sparrow and it formed sporodochia of this fungus. Five species including F. moniliforme were isolated from plant hopper collected from paddy fields in September. To select seed a disinfectant, twelve fungicides were tested and P242 was one of the best effective fungicidetested. After seed treatment with the fungicide, F. moniliforme was not isolated from hulls but was frequently isolated from brown rices.

The purpose of this study was to isolate and characterize fungal deteriogens, which induce discoloration of the cement tunnel, and calcite forming bacteria (CFBs), which have antifungal activity against fungal deteriogens. Isolation of mold, bacteria and yeast was performed using several solid media and partially identified using internal transcribed spacer (ITS); 5.8S rRNA gene sequencing and 16s rDNA sequencing. A total of 19 microbial strains were identified with the most widely distributed fungal strain being Cladospirum sphaerospermum. In addition, five bacteria derived from the tunnel were identified as CFBs. Amongst the latter, Bacillus aryabhatti KNUC205 exhibited antifungal activity against Cladospirum sphaerospermum KNUC253 and Aspergillus niger KCTC6906 as concentrated filtered supernatants.

The protein contents of soy protein isolate (SPI) and soft wheat flours were 83.5% and 8.5%, respectively. The addition of SPI increased the protein content but decreased the sedimentation value. Alkaline water retention capacity (AWRC) value increased with SPI addition and was highly correlated with protein content. Increasing SPI flour content significantly decreased the maximum, minimum and final viscosities. Mixograph peak time was positively correlated with protein content and AWRC. The PH and specific gravity of the cake batter increased with increasing SPI content. The SPI addition reduced the loaf and specific loaf volume compared with soft wheat flour. The lightness of the cake crust decreased, while the redness and yellowness increased, with SPI flour addition. SPI addition resulted in a decrease of overall acceptability, but an increase in hardness.

Recycling glass fiber, 'F-fiber,' was obtained by the separation of the roving layer from waste FRP and the concrete products or structures were considered for its application. Experiment was carried out for the bending strength of aggregate (2.45 of cement) by weight and F-fiber (density of 1.45, volume ratio to all of the aggregate and the cement). Whereas the specimen containing 1% F-fiber showed the bending strength 23% higher than that without F-fiber after curing far 28 days, the one with 0.5% F-fiber did not give any change. It could be found, therefore, that the minimum mixing amount should be larger than 0.5% fur the strength reinforcement. One of the reinforcing concrete product, bench flume, containing 1% F-fiber showed 21% increment of bending strength In contrast to that without F-fiber.

Conidia and cultural characteristics of isolates of chromogenic and teleomorphic strains of Colletotrichum gloeosporioides from apple and red pepper were compared. The mycelial growth of teleomorphic strains was faster than that of chromogenic strains in potato dextrose agar and V-8 agar. The chromogenic isolates from apple and red pepper developed. white gray to gray green mycelial rings interspersed with salmon to apricot colored conidial masses in colonies on potato dextrose agar and V-8 agar and none formed on ascigerous stage in cultures. The chromogenic isolates from red pepper produced conidia, most with one apex attenuated on apple and potato dextrose agar whereas fusiform and smaller conidia were produced in V-8 agar and water agar leaf medium. The chromogenic isolates from apple produced fusiform conidia in the media tested. The teleomorphic isolates from apple and red pepper produced cylindrical conidia, most with both apices rounded, developed white gray to dark olive green in a zonate pattern with small dark spots throughout colonies and formed the ascigerous stage in cultures.
