2Dn(3)(9 n=2m +1 not a prime) CAN BE CHARACTERIZED BY ITS ORDER COMPONENTS
Guiyun Chen,Huaguo Shi 한국전산응용수학회 2005 Journal of applied mathematics & informatics Vol.19 No.1-2
In this paper we prove that if G is a finite group, 2Dn(3)(9 ≤ n =2m +1 not a prime), G and M have the same order components, then

Objectives This study examined feasibility and reliability of a mobile application to measure depression in breast cancer patients. Methods Forty-two breast cancer patients from the Department of Surgery at Asan Medical Center were included in the study. The Beck Depression Inventory (BDI), EuroQol Five Dimensional Questionnaire, and EuroQol Visual Analogue Scale were assessed at baseline and twice after surgery at regular intervals. The Patient Health Questionnaire-9 (PHQ-9) was delivered by as a push notification via mobile application every two weeks for 12 months. Feasibility was calculated using number of respondents and total number of PHQ-9 completed. Reliability was calculated from the relationship between PHQ-9 and BDI scores obtained within each two week period. Agreement between PHQ-9 and BDI scores in the diagnosis of depression was evaluated by kappa statistic and McNemar s test. Results One thousand and ninety-two notifications for PHQ-9 were sent, and 622 responses were reported (compliance rate=57%). The compliance rate was not related to demographic factors except for the date of the first use of the application. Pearson s r between PHQ-9 and BDI scores was 0.599 (p<0.001), and kappa analysis demonstrated moderate level of agreement in diagnosis of depression (κ=0.431). Conclusion The compliance rate for patients reporting their symptoms by mobile application is high and the scores of PHQ-9 and BDI are correlated, which suggests that the mobile data measuring depression is reliable. However, this is a preliminary study and further study is needed to determine other factors that influence compliance rate.

A finite group G is called an NSN-group if every proper sub-group of G is either normal in G or self-normalizing. In this paper, thenon-NSN-groups whose proper subgroups are all NSN-groups are deter-mined.

It is proved that if M = Bp(3) orCp(3), p is an odd prime, G is a finite group and has the same order components of M, then G <기호>Bp(3) or Cp(3). It is proved that if M = Bp(3) orCp(3), p is an odd prime, G is a finite group and has the same order components of M, then G <기호>Bp(3) or Cp(3).

A finite group G is called a QNS-group if every minimal subgroup X of G is either quasinormal in G or self-normalizing. In this paper the authors classify the non-QNS-groups whose proper subgroups are all QNS-groups.

The present work is aimed at studying the synergistic catalysis of the bimetal ZIFs containing Co and Znmetal ions prepared by solvothermal method in the degradation of organic pollutants under ambientconditions. The bimetal mixed ZIFs were further characterized by some techniques such as XRD, SEM,TG-DTG, XPS, UV–vis, ESR, and N2-adsorption. Interestingly, the sample prepared with equal metal ions(1Zn:1Co) showed the highest catalytic performance for methylene blue (MB) degradation (94.10 %). Thismay be associated with the interaction between cobalt and zinc within the adjacent lattice, which makethe MB molecule to be easily adsorbed and degraded on empty electron orbit. Furthermore, the highestdegradation of MB was achieved with 98.83 % under the optimized conditions (catalyst weight of 50 mg,pH of 5, 3 h, 30 C). Besides, the various substrates such as methyl orange, indole, rofloxacin, methyl blue,and tetracycline were also investigated under the same conditions. Additionally, the DFT calculationresults suggested the more orbital distribution (LUMO, HOMO) of ZIF(1Zn:1Co) can result to more electronsbeing easily captured, and generate more radicals via electron transfer. Finally, the photocatalyticdegradation of MB is consistent with the first law of kinetics, and the activation energy is 26.797 KJ/molin the presence of ZIF(1Zn:1Co).
