To develope a solid culture media for the mass culture of Beauveria bassiana conida, wheat bran was selected as C source and N source. The pellet media were prepared without(P-I) and with(P-II) solidified ingredient. The moisture for the growth of B. bassiana was required over 4 : 2 of Media : D.W (W/V). The growth of Beauveria bassiana on the media type was more effective in media of pellet type than that of powder type. In addition, production of Beauveria bassiana conidia on the media size was more effective in media of S type($\Phi$3mm) than that of L type($\phi$7mm). And the yield of Beauveria bassiana conidia at 2$0^{\circ}C$ cultivation on 3 weeks post inoculation was similar to that of $25^{\circ}C$. Above-mentioned results showed that pellet medium (P-I) was effective to growth of Beauveria, suggesting that the pellet media may be useful in the mass production of Beauveria bassiana conidia.

It has been little known when an Artinian point quotient has the strong Lefschetz property. In this paper, we find the Artinian point star configuration quotient having the strong Lefschetz property. We prove that if ${\mathbb{X}}$ is a star configuration in ${\mathbb{P}}^2$ of type s defined by forms (a-quadratic forms and (s - a)-linear forms) and ${\mathbb{Y}}$ is a star configuration in ${\mathbb{P}}^2$ of type t defined by forms (b-quadratic forms and (t - b)-linear forms) for $b=deg({\mathbb{X}})$ or $deg({\mathbb{X}})-1$, then the Artinian ring $R/(I{\mathbb_{X}}+I{\mathbb_{Y}})$ has the strong Lefschetz property. We also show that if ${\mathbb{X}}$ is a set of (n+ 1)-general points in ${\mathbb{P}}^n$, then the Artinian quotient A of a coordinate ring of ${\mathbb{X}}$ has the strong Lefschetz property.

In this paper, we examined the problem of the structural stability according to the patch load of a rectangular plate that reflects the material properties of A6082-T6 is used primarily for marine plant structure. it applied to the four patch loading shapes, the effect of aspect ratio, a boundary condition and calculated the critical elastic buckling load. Calculating the critical elastic buckling load, During the eigenvalue buckling analysis it is applied to the shell181 as 4 node shell element. when the plate subjected to patch loading compare to the plate under a uniform axial compression load, it is possible observed to occur the different elastic buckling behaviour and it could be confirmed that it is affected significantly on a variable position and type of loadings, such as the effect of the aspect ratio. Also, Critical elastic buckling load according to th patch loading type in simply supported rectangular plate a/b=1.0, ${\gamma}b$=200mm are calculated 67%(Loading type I), 119 %(Loading type II), 76 %(Loading type III), 160 %(Loading type IV), respectively. Loading type I and III could be determined with the strong elastic buckling behavior much more than Loading type II and IV.

Body measurement was held for the subjects of Chinese adult males in their 20s through 40s residing in the Ningbo area of Zhejiang Province in order to provide body type information and raise the fit of clothing products for the advancement into the Chinese market. The following sums up the analysis of body types based on body measurement: 1. Seven factors to compose body types were produced from the analysis of males in their 20s, explaining 76.07% of variables and representing 3 types according to cluster analysis. Type 1 was H-b and appeared as much as 32.14%. Type 2, semi X-d, was 40.81%, while Type 3, A-i, had 27.04%. 2. Eight body type composing factors were extracted from the analysis of men in their 30s and 40s. The factors explained 76.77% of all the variables and represented 4 types according to cluster analysis. Type 1, H-d, had the appearance rate of 18.47%; Type 2, H-b, 40.84%; Type 3, Y-i, 27.71%; and Type 4, semi X-s, 11.95%.

The neurotoxin of Clostridium botulinum type B was purified from a liquid culture. The purification steps consist of ammonium sulfate precipitation of whole culture, treatment of Polymin P(0.15%, v/v), gel filtration on Sephadex G-100 at pH5.6 and DEAE-Sephadex charomatography at pH8.0. The procedure recovered 17% of the toxin assayed in the starting culture. The toxin was homogeneous by sodium dodecyl sulfate(SDS)-polyacrylamide gel electrophoresis and had a molecular weight of 163, 000. Subunits of 106, 000 and 56, 000 molecular weight were found when purified toxin was treated with a disulfide-reducing agent and electro phoresed on SDS-polyacrylamide gels.

The fabrication and characteristics of HTS race-track type field coil for generators was carried out. Field coils are composed of 3 pancake coils wound by 37-filamental Bi-2223/Ag-alloy tapes. The winding machine is horizontal type. The critical currents (I$_c$) of the superconducting tapes were measured with variation of bending strain and external magnetic fields. I$_c$ of both whole field coils and 3 pancake coils were measured as a function of temperature. At 77K under the self-field, I$_c$ of whole field coils was 12A, while in the case of middle pancake coil, I$_c$ was 15A. The distribution of magnetic field B was obtained, using 3-D FEM. Our simulation showed that maximums of B${\bot}$A in x-y plane were locally distributed in both the upper and the lower coils. In addition, the fabrication processes and the characteristics of field coil are described.

To investigate the cycle and relative frequences and the fine structure of seminiferous epithelia in mature Jindo dogs, histologic study was performed. The results obtained were summarized as follows; 1. Type A spermatogonia appeared approximately 1.6 times as many at stage II as compared to stage I while type In spermatogonia appeared small amount in stage III, IV and V. type B spermatogonia were found during the stage VI to VIII, though not detectable during stage I to V. The type B spermatogonia divided at stage VII to produce the preleptotene primary spermatocytes at stage VIII. The number of primary spermatocytes of the leptotene phase markedly increased during stage I to II, and the primary spermatocytes of the pachytene phase were shown the least in number at stage IV. The secondary spermatocytes could be seen only at stage IV. 2. The relative frequencies of each stage from stages I to VIII of the cycle of seminiferous epithelia were 31.6, 11.9, 10.0, 3.2, 8.2, 10.1, 11.7 and 13.2% respectively. 3. On electron microscopic observations, acrosomal vesicle of spermatids appeared larger though the bulk of germ cells were the morphologically same as those of the other animal species. Thread line structures light microscopically observed in the cytoplasm of Sertoli cell were the longitudinal orientation of mitochondria.

From the 70% EtOH extract of the roots of Astragalus membranaceus (Leguminosae), fifteen saponins were isolated and identified as astragaloside I (1), isoastragaloside II (2), astragaloside II (3), agroastragaloside I (4), cyclogaleginoside B (5), cycloaraloside A (6), brachyoside B (7), agroastragaloside II (8), astragaloside III (9), astragaloside IV (10), astramembranoside A (11), astramembranoside B (12), cylocanthoside E (13), cyclounifolioside B (14) and azukisaponin V methyl ester (15) by spectroscopic methods. Ten compounds 1 - 3, 5 - 7, 9 - 11 and 14 have cycloastragenol as an aglycon, and four compounds 4, 8 , 12, and 13 have cyclocanthogenin as an aglycon. The hairy roots of A. membranaceus were shown to produce previously unreported cycloartane-type saponins such as agroastragalosides I (4) and II (8) and cycloastragenol $3-O-{\beta}-D-xyloside$ (5), together with the known saponins. This is the first report of these saponins (4, 5, and 8) from the intact plant. Although the occurrence of the oleanane-type triterpene saponin, azukisaponin V methyl ester (15), in Astragalus plants has been demonstrated by others, this is the first report of the azukisaponin V methyl ester (15) from the Astragalus plants.

In epistatic grouping of uvs genes in A. nidulans based on the sensitivities to 4-NQO, the same epistatic grouping was obtained as those for UV and MMS-sensitivities. Based on the MMS-sensitivities, uvsA demonstrated synergistic interactions to uvsF and uvsH, the UvsF group genes, but exhibited epistatic interactions to uvsB and uvsC. The same epistatic grouping was also seen for uvsI when UV was irradiated after 4h germination of conidia, showing synergistic interactions to uvsH, uvsC, and uvsB. However, epistatic interactions were observed with uvsF, which were different from those obtained in quiescent conidia by UV. Intergenic and intragenic recombination frequencies were normal in uvsI compared with wild type.

The author observed the positional relationship of maxillary cuspid to ala-lacrimal duct line in the 594 Koreans(329 male, 265 female) who had relatively normal teeth arrangement, aged 16 to 70. The relationship of ala-lacrimal duct line to the distal angie of maxilly cuspid of the subjects were classified as follows; Type A : Ala-lacrimal duct line was lotated more medially than the distal angle of maxillary cuspid. Type B : Ala-lacrimal duct line coincided with the distal angle of maxillary cuspid. Type C: Ala-lacrimal duct line was located more distally than the distal angle of maxillary cuspid. The occlusal relationship of the maxillary first molar to the mandibular first molar of the subjects were classified as follows; Group I : Group of neutrocclusion relationship. Group II : Group of distocclusion relationship. Group III : Group of mesiocclusion relationship. The obtained results were as follows; 1) The positional relationship of maxillary cuspid to ala-lacrimal duct line were as follows; (Male) Type A: $68.5%{\pm}1.58m%$, Type B: $22.5%{\pm}2.30m%$, Type C: $9.1%{\pm}\1.58m%$ (Female) Type A : $64.5%{\pm}2.94m%$, Type B: $26.5%{\pm}2.71m%$, TypeC: $8.9%{\pm}1.73m%$ 2) Ala-lacrimal duct line located more distally in group II and group III than group I at the point of the positional relationship of upper and lower first molar. 3) Average distance and standard deviation in type A were as follows; (Male) Right: $2.17mm.{\pm}1.01mm.$ Left: $2.27mm.{\pm}1.02mm.$ (Female) Right: $2.06mm.{\pm}0.70mm.$ Left: $2.24mm.{\pm}0.80mm.$ 4) Average distance and standard deviation in type C were as follows; (Male), Right: $1.47mm.{\pm}0.85mm.$ Left: $1.52mm.{\pm}0.97mm.$ (Female) Right: $1.04mm.{\pm}0.44mm.$ Left: $1.26mm.{\pm}0.89mm.$ The results of 3) and 4) had no significant difference between the male and female.
