Thirteen strains of Bacillus thuringiensis were isolated from soil in Korea and characterized. The all strains produced parasporal crystals and spores in their cells. Two strains had bipyramidal crystals, seven strains contianed round ones and four strains had unregular ones. Only minor biochemical characteristics of the thirteen isolates were different and distinctive, however general characteristics were similar to the known serotypes of B. thuringiensis. Two strains were resistant to ampicilin. Three strains were resistant to bacitracin, six strains were resistant to cephalothin, two strains were resistant to colistin, HL-68 strain was resistant to gentamycin, HL-67 strain was resistant to kanamycin and HL-71 was resistant to tetracycline. Two strains were resistant to penicillin G. Four strains were toxic to Bombyx mori larvae and eleven strains were toxic to Culex pipiens larvae.

The purpose of this study is to develop a science writing teaching strategy, and to apply it to the fourth-graders in elementary science classes. We examined its effect on their motivation, attitude, and understanding of science concept. For the research fourth grade children were grouped into three classes: an experimental class A of 27 children, an experimental class B of 24 and a comparative class of 27. All of them are from H elementary school in Seoul, Korea. Experimental class A learned science writing with a newly developed strategy while experimental class B learned science writing in a traditional method. Comparative class did not learn science writing. As a result, class A showed positive changes on students' science motivation, attitude, and understanding of science concept. In addition, class B with even one science writing task for a chapter had higher achievement in the understanding of science concept than the comparative class had.

An observational study on the recurrences of left abomasal displacement after surgical correction was conducted in 178 Holstein cows. The correction methods were right flank omentopexy (A), right ventral paramedian abomasopexy (B) and left flank abomasopexy (C). Four(5.4) out of 74 cows by method A, 2(2.0) out of 101 cows by method B and 1(33.3%) out of 3 cows by method C had the recurrence of the disease after the first operation. As for the method A, 3 cows and a cow recurred 13-18 months and 27 months after the first operation, respectively. As for the method B, recurrence of the disease in two cows occurred 14 and 19 days after surgery, respectively. In a cow which had been indicated by method C, the recurrence was recurred 14 months after the operation.

Improved hypophysectomy technique and the efficacy of bGH in hypophysectomized female rats were studied as a basis for the function of endocrine gland and hormones. 1. With improved sublaryngeal a, pp.oach by hypophysectomy, 34 rats out of 40 were successfully hypophysectomized(more than 80% of success). The surgical time for hypophysectomy per rat was taken about 3.0$\pm$1.0 min. 2. For the effect of hypophysectomy and bGH on body weight gain among the 5 gruops of A, B, C, D, and E, the weight gains for A, B, C, D, and E, were 93g, 9.2g, 10.7g, 25.1g and 36.2g, respectively, which implied that hypophysectomy had a major effect on body weight. And also, the effect of bGH was paralleled with the level of bGH. There were significant difference between control and hypophysectomized groups, and between the bGH treated and bGH non-treated groups after hypophysectomy(p<0.01). 3. For the effect of hypophysectomy and bGH on the length of femur, tibia, humerus, and anterbrachi, longest was for A, shortest for B, and longer in order of C, D, and E. The A group was significantly longer than B, C, D, and E groups. The B group was shorter than C, D, and E groups(p<0.01). 4. For the effect of hypophysectomy and bGH on the weight of femur, tibia, humerus, and antebrachi, heaviest was for A, lightest for B, and heavier in order of C, D, and E. The A group was significantly heavier than B, C, D, and E groups. The B group was lighter than C, D, and E groups(p<0.01). 5. In changes of body length, and weights of liver and heart, A group was most drastically increased. Among the hypophysectomized groups, the change was increased in order of B, C, D, and E. Especially, the change of A group was significantly greater than B, C, D and E gruops. However, no significant differences were found among B, C, D, and E groups. 6. The hypophysectomy in rat had a significant effect on body growth. The effect of hormone was remarkably different depending upon the level of hormone. It was found that 300$\mu\textrm{g}$ of bGH/kg of body wt/day was slightly lower for normal growth.

Background: The purpose of this study was to investigate the efficacy of muscle energy techniques (MET) of upper trapezius and sternocleidomastoid muscles on Bell's palsy. Methods: In this retrospective study, we screened the medical records of patients with Bell's palsy who had received inpatient and outpatient treatment at the Department of Acupuncture & Moxibustion, Korean Medicine Hospital Dong-Eui University between November 28, 2016 and April 30, 2017. A total of 34 out of 93 Bell's palsy patients met the inclusion criteria. The 34 patients were divided into two groups: Group A patients had undergone Korean-Western combination treatment and MET of upper trapezius and sternocleidomastoid muscles; Group B patients had undergone Korean-Western combination treatment only. MET of upper trapezius and sternocleidomastoid muscles had been performed three times a week during the inpatient period, and two to three times a week during the outpatient period. Yanagihara scores had been assessed at the first visit, and 1, 2, 3, and 4 weeks after the first visit. Results: Group A Yanagihara scores were significantly improved during each interval from the first visit to 4 weeks later. Group B Yanagihara scores were also significantly improved except during the first week. During every period, the improvements observed in Yanagihara score were significantly higher in Group A than in Group B. Conclusion: These results suggest that MET of upper trapezius and sternocleidomastoid muscles may be effective treatment for Bell's palsy.

Background: The current standard treatment for patients with newly diagnosed diffuse large B cell lymphoma (DLBCL) is rituximab combined with cyclophosphamide, doxorubicin, vincristine and prednisolone (CHOP). A significant number of patients were not treated with recommended dose of rituximab due to limited financial resources in Malaysia. This study evaluates the efficacy of R-CHOP like chemotherapy in Malaysian patients with DLBCL. Materials and Methods: The study comprised a retrospective analysis of patients with DLBCL treated at a single centre. The outcome was compared with patients who were treated with R-CHOP like and CHOP like chemotherapy. Patients who were treated with lower dose of rituximab was subanalysed for outcome. Results: A total of 86 patients who had CHOP-like chemotherapy were included. Only 39 (45%) patients had rituximab and only 12 (29%) patients had the recommended dose. The overall response (OR) and complete response (CR) rates were 88% and 81% respectively. There was no significant difference in OR and CR in patients who had rituximab and those without rituxmab. Those with International Prognostic Index (IPI) score of ${\leq}2$ had significant higher CR rate, progression free survival (PFS) and overall survival (p<0.001). Conclusions: The lack of significant improvement in CR and DFS in our patients may be due to an inadequate dose of rituximab.

Purpose: The aim of this study was to investigate the accuracy of cone-beam computed tomography (CBCT) in the diagnosis of vertical root fractures in a tooth with gutta-percha and prefabricated posts. Materials and Methods: This study selected 96 extracted molar and premolar teeth of the mandible. These teeth were divided into six groups as follows: Groups A, B, and C consisted of teeth with vertical root fractures, and groups D, E, and F had teeth without vertical root fractures; groups A and D had teeth with gutta-percha and prefabricated posts; groups B and E had teeth with gutta-percha but without prefabricated posts, and groups C and F had teeth without gutta-percha or prefabricated posts. Then, the CBCT scans were obtained and examined by three oral and maxillofacial radiologists in order to determine the presence of vertical root fractures. The data were analyzed using IBM SPSS 20.0 (IBM Corp., Armonk, NY, USA). Results: The kappa coefficient was $0.875{\pm}0.049$. Groups A and D showed a sensitivity of 81% and a specificity of 100%; groups E and B, a sensitivity of 94% and a specificity of 100%; and groups C and F, a sensitivity of 88% and a specificity of 100%. Conclusion: The CBCT scans revealed a high accuracy in the diagnosis of vertical root fractures; the accuracy did not decrease in the presence of gutta-percha. The presence of prefabricated posts also had little effect on the accuracy of the system, which was, of course, not statistically significant.

This study was to determine the characteristics of vapor-permeable waterproof finished fabric by the coating method. 4 different kinds of coating fabrics (A : wet, porous, polyurethane, B : dry, no porous, polyurethane, C : shape memory polyurethane and D : dry, porous polyurethane) were used, which were developed recently With this sample, moisture transport rate ($40^{\circ}C$, 45%RH & $40^{\circ}C$, 95%RH), changes of coating side's shape by washing times, water repellency rate, contracted length, qmax, heat conductivity, heat keeping rate, heat keeping rate with cotton, heat keeping rate on humidity temperature and humidity within clothing etc. were checked. And it was done in a climate chamber under $20{\pm}2^{\circ}C$, $65{\pm}5%RH$. The results of this study were as follow; In the moisture vapor transmission of sample B and C increased on high temperature and high humidity while sample A and D decreased, on this condition. Qmax rate had high relation with ground fabric's surface properties and the order was A>C>D>B. Heat conductivity had high relation with thickness and surface properties. Heat keeping rates on sweat condition showed around half percents of heat keeping rates on normal condition, but had no relation with moisture vapor transport rate. Changes of the fabric's properties by washing times were different in accordance with the construction of fabrics and the coating resin. Sample C had tow heat keeping rate on the high temperature and humidity and high heat keeping rate on the low temperature and humidity Moisture transport rate of vapor-permeable waterproof finished fabrics had high relation with the properties of ground fabrics on low humidity condition, but on the high humidity condition, it was highly related with the properties of coating resin.
