To develop a new cultivar of King oyster mushroom white variety (Pleurotus ferulae), GW10-95 as parental strain was selected by the method of Di-mon crossing between monokaryotic strain ASI 2850-24 derived from ASI 2850 and dikaryotic strain ASI 2803. The GW10-95(ASI 2803 ${\times}$ ASI 2850-24) was shown the best cultural characteristics, selected to be a new cultivar and designed as 'Beesan No.1'. The 'Beesan No.1' was formed incompatibility line distinctly in the confrontation growth of parental strains ASI 2803 and ASI 2850. Analysis of the genetic characteristics of the new cultivar 'Beesan No.1' showed a different DNA profile as that of the control strains, ASI 2803 and ASI 2850, when RAPD(Random Amplified Polymorphic DNA) primer URP6 was used. The optimum temperature and pH arrange for mycelial growth were $25^{\circ}C$ and pH5~8, respectively. Fruiting body production per bottle was about 245 g using demonstration farms. And also the stipe was thick and long. This new cultivar 'Beesan No.1' of Pleurotus ferulae was characterized by fast fruitbody formation, the stipe was thick and long and high quality yield compared to that of other cultuvars. We therefore expect that this new strain will increase of farmer's income by construction of stabilized production system.
To develop a new cultivar of king oyster mushroom(Pleurotus eryngii), G09-21 as parental strain was selected by the method of Di-mon crossing between monokaryotic strain ASI 2824-21 derived from ASI 2824(Keunneutari No. 2) and dikaryotic strain ASI 2887(Aeryni 3). The Pe21-53(G09-21-10 x ASI 2844-9) was shown the best cultural characteristics, selected to be a new cultivar and designated as 'Seolsong'. The 'Seolsong' was distinctly formed incompatibility line in the confrontation growth of parental strains Keunneutari No. 2, Aeryni 3 and ASI 2844. Analysis of the genetic characteristics of the new cultivar 'Seolsong' showed a different DNA profile as that of the control strains, Keunneutari No. 2, Aeryni 3 and ASI 2844, when RAPD(Random Amplified Polymorphic DNA) primer URP4 was used. The optimum temperature and pH arrange for mycelial growth were $25{\sim}30^{\circ}C$ and pH 5~8, respectively. This new cultivar 'Seolsong' of fruiting body production per bottle was about $131.4{{\pm}}43.1$ g which is about 102% quantity compared to that of other cultivar Keunneutari No. 2. And also the stipe is thick and long, but the number of available stipe is few. Particularly, it was tolerant of high moisture above 90% during the growth period after primodia formation. We therefore expect that this new strain will save of labor and cost of cultivation by without culling work.

Shigella strains isloated in the Teagu area during the period from 1973 to 1985 were studied for species distribution, drug resistance, and R plasmids. Approximately 1,200 strains were isolated during this period, and most of them were classified into Shigella flexneri, S. sonnei occupied less than 20%, and S. dysenteriae and S. boydii were very rarely isolated. More than 95% of them were resistant to one or more of these drugs; chloramphenicol (Cm), tetracycline (Tc), streptomycin (Sm), sulfisomidine (Su), ampicillin (Ap), and trimethoprim (Tp). Strains resistant to kanamycin, nalidixic acid (Na), and rifampin (Rf) were rare, and no strain was resistant to cephaloridine, gentamicin, and amikacin. Approximately half of the isolates were resistant to drugs in 1973, but the rate of resistant strains increased to more than 95% from 1977. Strains resistant to the four drugs (Cm, Tc, Sm, and Su) occupied the majority of resistant strains until 1977, but the most prevalent multiplicity of drug resistance increased to six drugs (Cm, Tc, Sm, Su, Ap, and Tp) from 1978 with the marked increase of Ap- and Tp-resistant strains. Approximately 75% of them transferred resistance to Escherichia coli by conjugation, and the resistance was considered to be mediated by R plasmids. Almost all of them transferred the complete patterns of resistance to drugs except Na and Rf. However, among some strains of recent isolates, small numbers of segregants of transferred resistance were observed. The R plasmids in Shigella were mostly classified into Inc FII, and only small numbers into Inc B. Segregants were in most cases unclassified.
The purpose of this study was to analyze the current states of interior design as a major at vocational high schools and to suggest ways in which it can be improved. Three hundred and four students and twelve teachers of two vocational high schools comprised the sample population for this study. Data was collected using two methods, questionnaires and interviews. Frequency distribution, mean, and chi-square tests were used to analyze the data. The findings of this study are as follows: The student respondents were more interested in studying residential design, furniture design and making, drafting and perspective drawing than other areas of study. Most teachers had difficulties teaching the subject of residential design because they were not well educated with this area. Surprisingly most students hoped to extend their education to a university or college after graduation, not to enter the workforce. According to teachers'responses, almost ninety percentage of students entered university or college. And more than two thirds of the students desired to study an interior design related major at the university level. Among graduates having jobs, half of them were working in interior design fields. If the students had to choose their jobs, they would work in interior design fields. The variables differentiating several related careers after graduation were school, grade, and sex. The students viewed interior design, interior coordination, and CAD related work as fields likely to enter upon graduating from vocational high schools; however, teachers viewed furniture making, interior accessorizing, and home fashion as fields more appropriate to the students'level of training. The teacher respondents criticized the textbooks in four categories; suitability with the students'level was average or below average; students'interest level and students'understanding level were average or above average; and whether the book was easy or difficult to be utilized for the purposes of teaching was also average or above average. The criticism was a little diverse depending on each book or each chapter. The teachers pointed out several problems using those books, such as insufficient examples or explanation, lack of coherence between some chapters, and an incompatibility with the allotted time frame in class. The merits of the textbooks varied such as a well organized structure, ability to generate students'interest. This study revealed that the strategy for improving the interior design major at vocational high schools should invoke, 1) dividing students into two groups-one to enter a university; the other to have jobs after graduation to focus their interests. 2) improving textbooks more appropriate to the students. 3) providing present teachers the opportunities for in-service training and hiring new teachers with credentials more suitable to educate students who desire to be interior designers.

The vehicle-track structure dynamic interaction analysis problem can be treated as sliding contact problem, and it is assumed that vehicle run at a constant speed over a rail modeled as beam elements. Unfortunately, Salome-Meca can not satisfy the compatibility condition for the beam master elements, which are consist of the elements with higher order polynomial shape function, in sliding contact problem. In this study, it is suggested to use more finer beam master element mesh as the remedy for incompatibility in sliding contact problem, and the accuracy of the solution is secured. For this, the effect of beam element mesh refinement consisting runway is analysed through simple examples, and the applicability to the dynamic interaction analysis is evaluated. Finally, the dynamic interaction analysis of railway skewed culvert transition problem is carried out to evaluate the effect of supporting stiffness due to backfill pattern changes and track irregularity due to uneven subgrade settlement.

Transfusion related acute lung injury (TRALI) is a serious, potentially life-threatening complication of transfusion therapy that is sometimes under diagnosed and under reported. Patients with TRALI present with dyspnea/respiratory distress and fever. The symptoms, signs and chest radiological findings in TRALI are similar to transfusion associated circulatory overload, which makes it is difficult to distinguish it from circulatory overload. Although the mortality rate in cases of TRALI is relatively low, TRALI is the third most common cause of fatal transfusion reactions next to ABO blood type incompatibility and hepatitis. Mild-to-moderate cases of TRALI may be misdiagnosed as volume overload. Recently, we encountered two cases where the patients suffered from dyspnea and fever after a transfusion. and review of the relevant literature.

In Japan, the vacancy rates of office buildings have been at high in big cities since 1992. This problem is especially acute in Tokyo, where it is estimated that over 2.27 million square meters of office floor area will be oversupplied in 2003: big urban redevelopment projects will be completed in 2003. Under these circumstances, International Cooperative Research and Development on Sustainable Urban Management by Conversion of Buildings, called “SUMCOB”, has been carried out. This research aims to regenerate urban areas by converting redundant offices into flats, although instances of conversion are still very few in Japan. This paper introduces part of current results by SUMCOB, and discusses legal problems with conversion and basic capacity of vacant offices in Tokyo. It has been confirmed that there are no constraints concerned with Real Estate Registration Law (although it requires the change of the registration after conversion). and City Planning Law. However, some criteria are incompatible with Building Standard Law and Fire Service Law if the use of the building is changed from offices to flats. Typical incompatibility between offices and flats is lightening. If the buildings do not satisfy criteria for flats, the cost of renovation works for conversion will increase. To examine the basic capacity of vacant office buildings for conversion, field surveys in Tokyo have carried out at three areas: Kodenmacho (Chuo-ku), Toranomon (Minato-ku), and Iwamonocho (Chiyoda-ku). They are typical office areas that are included in center core of Tokyo. In Chuo-ku, the oldest commercial area in Tokyo, textile merchants have been located their headquarters. In Minato-ku, many rental office buildings have been located and several large scale redevelopments are advancing. Chiyoda-ku includes Marunouchi area, which is the prime office area in Japan. Thirty percent of the buildings in survey areas suffer from over twenty percent vacant floor rate, and fifty five percent were constructed before 1990. Especially most of buildings over forty percent vacant floor rate were constructed in 1980s. Vacant office problems haven't been seen in old buildings in Tokyo yet. The number of dwelling units made from office space will influence the conversion scheme. Seventy percent of the office buildings in survey areas have floor area of less than two hundred square meters. If they have been subdivided into two bedrooms type or three bedrooms type, the number of dwelling units in a floor would be less than three. The difficulty of conversion planning derives from frontage size, depth size, and their proportion. The five categories are proposed to grasp actual requirements for converting offices into flats.

A previous study on the model coatings based on latex-bound plastic pigment coatings (1) has been extended to latex-bound No. 1 clay, ultra-fine ground calcium carbonate (UFGCC), and clay-carbonate pigment mixture coatings, which are being widely used in the paper industry. The latex binder used was a good film-forming, monodisperse S/B latex or 0.15$\mu\textrm{m}$. No. 1 clay was representative of plate-like pigment particles, whereas UFGCC was of somewhat rounded rhombohedral pigment particlel. Both of them had negatively skewed triangular particle size distributions having the mean particle suet of 0.7${\mu}{\textrm}{m}$ and 0.6$\mu\textrm{m}$, respectively. Their packing volumes were found to be 62.5% and 657%, respectively. while their critical pigment volume concentrations (CPVC's) were determined to be 52.7% and 50.5% ( average of 45% caused by the incompatibility and 55.9% extrapolated) by coating porosity, respectively. Each pigment/latex coating system has shown its unique relationship between coating properties and pigment concentrations, especially above its CPVC. Notably, the clay/latex coating system hat shown higher coating porosity than the UFGCC/latex system at high pigment concentrations above their respective CPVC's. It was also found that their coating porosity and gloss were inter-related to each other above the CPVC's, as predicted by the theory. More interestingly, the blends of these two pigments have shown unique rheological and coating properties which may explain why such pigment blends are widely used in the industry. These findings have suggested that the unique structure of clay coatings and the unique high-shear rheology of ground calcium carbonate coatings can be judiciously combined to achieve superior coatings. Importantly, the low-shear viscosity of the blends was indicative of their unique packing and coating structure, whereas their high-shear rheology was represented by a common mixing rule, i.e., a viscosity-averaging. Transmission and scanning electron and atomic force microscopes were used to probe the state of pigment / latex dispersions, coating surfaces, freeze fractured coating cross-sections, and coating surface topography. These microscopic studies complemented the above observations. In addition, the ratio, R, of CPVC/(Pigment Packing Volume) has been proposed as a measure of the binder efficiency for a given pigment or pigment mixtures or as a measure of binder-pigment interactions. Also, a mathematical model has been proposed to estimate the packing volumes of clay and ground calcium carbonate pigments with their respective particle size distributions. As well known in the particle packing, the narrower the particle size distributions, the lower the packing volumes and the greater the coating porosity, regardless of particle shapes.
In this study, we performed ovule culture after reciprocal crosses of two Alstroemeria accessions and investigated genetic contribution of parents by using RAPD markers. The best method was half-ovule culture on MS medium supplemented with $60g{\cdot}L^{-1}$ sucrose and $2.2g{\cdot}L^{-1}$ gelrite at 14 days after pollination. Embryos began to germinate after 6 weeks of culture. The complete plantlets were formed after 4 months of culture. In eight progenies and two parental cultivars, 59 polymorphic bands were obtained out of 89 total bands by RAPD analysis using 7 primers. Eight $F_1$ progenies from the crosses between two accessions using reciprocal crosses showed 1:1 contribution of maternal and paternal parents. It is confirmed that $F_1$ progenies were obtained from parental accessions by using RAPD markers. We conclude this cross combination showed pre-fertilization barriers with incompatibility between stigma or style, and pollen because progeny number was different in each cross combination. Thereby, it warrants overcoming pre-fertilization barrier together with post-fertilization barrier in order to broaden the heterozygosity within progeny populations in Alstroemeria breeding program.
