Prior to the concrete and practical use of closed schools, this study was designed to identify trends in the use of closed schools, and the possibility and direction of the library's use of closed schools based on the status of closed schools and use cases. As a result of the case analysis, the building of libraries using closed schools can be reborn as libraries with different characteristics from general public libraries, such as providing complex cultural spaces, eco-friendly spaces, and local community places. In addition, based on the results of the study, future direction of library closure is suggested as follows: Provide local economic contribution and local revitalization opportunities, life-friendly and friendly space for local residents, recycling space linked with elderly welfare, care service, urban to rural Immigrants, creation of added value and creation of local business using closed schools, environment-friendly space, recycling as a complex community center, recycled into a space that meets and complements local needs.

Alcaligenes sp. SH-69 can synthesize poly(3-hydroxybutyrate-co-3-hydroxyvalerate) from a single carbon source such as glucose. To clone the phaC gene from Alcaligenes sp. SH-69, a polymerase chain reaction was performed using the oligomers synthesized based on the conserved regions of the phaC genes from other bacteria. A PCR product (550 bp) was partially sequenced and the deduced amino acid sequence was found to be homologous to that of the phaC gene from Alcaligenes eutrophus. Using the PCR fragment Southern blotting of Alcaligenes sp. SH-69 genomic DNA digested with several restriction enzymes was carried out. To prepare a partial genomic library, about 5-Kb genomic DNA fragments digested with EcoRI, which showed a positive signal in the Southern blotting, were eluted from an agarose gel, ligated with pUC19 cleaved with EcoRI, and transformed into Escherichia coli. The partial library was screened using the PCR fragment as a probe and a plasmid, named pPHA11, showing a strong hybridization signal was selected. Restriction mapping of the insert DNA in pPHA11 was performed. Cotransformation into E. coli of the plasmid pPHA11 and the plasmid pPHA21 which has phaA and phaB from A. eutrophus resulted in turbid E. coli colonies which are indicative of PHA accumulation. This result tells us that the Alcaligenes sp. SH-69 phaC gene in the pPHA11 is functionally active in E. coli and can synthesize PHA in the presence of the A. eutrophus phaA and phaB genes.

A silkworm Bombyx mori genomic DNA library was constructed from polyphagous J111 strain and unpolyphagous $C_3$ strain to develop the genomic study by DNA makers. Genomic DNAs of two strains were digested with restriction enzyme EcoRI and ligated into pUC18. The ligated plasmids were transferred into E. coli host strain DH5$\alpha$. When the genomic DNAs were hybridized with insert DNAs from transformant, could be categorized from hybridization patterns to three groups as high repetitive sequence, moderately repetitive sequence, and low-copy number sequences. A total of 219 clones containing single or low-copy number sequence inserts were examined for any polymorphisms between two strains of J111 and $C_3$. Forty six clones showed RFLPs and 10 of these clones were used as a probe of analysis of $F_2$ population derived from crossing between J111 and $C_3$ strain. The genetic inheritance tested with each clones will be important tools to construct the genetic map of the silkworm, Bombyx mori.

A cDNA of coagulation Factor IX gene has been screened from the $\lambda$gt11 human fetal liver cDNA library, and used to construct a 2.8-kb full length cDNA after recombining with the N-terminal fragment from pTZ-FIX. Human genomic DNA was isolated, digested with the restriction endonucleases, TaqI, EcoRI, and HindIII, and Southern hybridization was performed using the full length factor IX cDNA as a probe. The hybridized bands generated by the restriction endonucleases were the followings: TaqI, 0.3, 1.0, 1.6, 1.8, 2.7, 3.7, and 5.3 kb bands; EcoRI, 1.8, 4.8, 4.9, 5.5, 6.8, and 12.6 kb bands; HindIII, 4.1, 4.4, 5.2, 5.8, 7.6, and 12.5 kb bands. When the Southern bands were physically mapped along the genome, about 50-kb continuous region harboring almost all of the genomic region of Factor Ⅸ gene was covered. These results suggest a possibility of using an exonal cDNA probe to diagnose abnormalities including large deletions, insertions, and rearrangements along the genome, if there is any.

Total genomic DNA library of Serratia marcescens was prepared by inserting Sau3AI partial digesting fragments(above 5 kb) into the dephosphorylated BamHl site of pUC19. In primary screening, two colonies were selected by observing the halo around E. coli transformants grown on the swollen colloidal chitin media. Secondary screening was performed by soaking two colonies with a few drops of 4-methylumbelleliferryl N-acetyl-$\beta$-D-glucocosaminide(4-MuNGlcNAc). As 4-MuNGlcNAc is a specific, fluorogenic substrate for chitinase, the positive clones produce light fluorescence by the exposure under the long wave U.V. light(360 nm). From genomic DNA library derived from pUC19, we have isolated two different chitinase clones, pCH1(11.0Kb) and pCH2(7.5Kb), which show completely different restriction map to each other. The cross-hybridization of pCH1EA and pCH2 have not revealed any hybridization signals to each other.

In this paper, we have established the procedures for $CO_2$ emission estimation BIM libraries by using the material takeoff function that BIM tools fundamentally provide, and verified its availability by applying to steel structures. The BIM library set-up procedures were made up of $CO_2$ emission coefficients and parameter extraction, project unit setting, parameter setting, and $CO_2$ emission quantity calculation formula set-up. We used Revit Architecture 2013 as BIM tool, and established the steel members' family libraries as BIM libraries. It is possible to calculate the $CO_2$ emission quantity by following the proposed BIM library set-up procedures, and users have only to input the $CO_2$ emission coefficients and unit weights of steel members being used. We expect that the results contribute to practical use of BIM in field, and vitalizations of the eco-friendly construction.

By SDS-polyacrylamide gel elcctrophoresis (SDS-PAGE) and immunoblot analysis that a protein with 66,000 daltons in size was recognized by P. aeruginosa anti-exotoxin A from P. sp. PY002. The yields of exotoxin A in P. sp. PY002 culture were influenced by the concentration of iron in the culture media. Increasing of the exotoxin A production and siderophore production was made slight increasing in the MKB medium. On the other hand, to clone the gene encoding the exoloxin A genomic library of P. sp. PY002 was constructed in pBluescript SK(+). From this library a exotoxin A homologous gene was isolated by immunological hybridization method using P. aemginosa anti-exoloxin A as a probe. Two putative clones were isolated and designated pETA23 and pETA42. Thc restriction analysis ol pETA42 demonstrated that thc 1760 bp insert contained one NcoI, PvuII, SstI, Kpnl and EcoRI site and three SmaI and HaeD sites.
