Jianguo CHE
Journal of Service Science and Management (JSSM) , 2009, DOI: 10.4236/jssm.2009.23024
Abstract: Multi-item and low-volume process is a production system with multi-input source, interactions between input variables, and frequently changes of system state, etc. Strong interactions between input variables and time-varying of input variables cause poor robustness and large variation range of output quality, which produces high cost, heavy waste and low efficiency of multi-item and low-volume process. Robustness optimization of multi-item and low-volume process is a new, important and need-to-deep research field with multi-item and low-volume production system prevails. It proposed a strategy enhancing robustness of multi-item and low-volume process by Taguchi robust design. Firstly, build and analyze a fitting output response model of multi-item and low-volume process after taking the adjustable variables (or time-varying variables) corresponding to each item and interaction between input variables into fitting output response model of multi-item and low-volume process as input variables uniformly, and treating the parameter value of time-varying variables corresponding to each item as level value of the adjustable variables (or signal factors) of process. Secondly, present robustness evaluation index based on evidential theory, desirability function and dual response surface etc. Finally, choose the proper experiment type and optimize the process. And then the robustness optimization of multi-item and low-volume process can be reached.

Abstract: Hubungan keluarga dalam kajian ini memberi tumpuan kepada aspek gayakeibubapaan dan pola komunikasi keluarga. Selain itu, kajian ini melihat kepentingan ciri anak dalam hubungan tersebut. Secara lebih khusus, kajian bertujuan mengkaji hubungan keluarga dari aspek gaya keibubapaan dan pola komunikasi keluarga dan juga hubungan ciri anak terhadap hubungan keluarga. Pemilihan sampel dijalankan dengan memilih pelajar di sekolah-sekolah di Terengganu dan seramai 435 pelajarterlibat dalam kajian ini. Pengumpulan data berdasarkan kepada soal selidik yang dijawab sendiri oleh responden. Pelajar menjawab empat bahagian soal selidik iaitu a) maklumat demografi, b) maklumat komunikasi keluarga, c) gaya keibubapaan dan d) maklumat personaliti. Sebanyak tiga alat kajian telah digunakan iaitu Revised FamilyCommunication Pattern, Parental Authority Questionnaire, dan Eysenck Personality Questionnaire-Revised. Kaedah analisis korelasi dan regresi digunakan dalam kajian ini. Analisis korelasi menunjukkan personaliti ekstrovert mempunyai hubungan signifikan dengan gaya keibubapaan autoritatif dan juga kedua-dua orientasi komunikasi perbualan dan orientasi konformiti. Analisis regresi pula menunjukkannilai pekali korelasi di antara gabungan pembolehubah personaliti dengan gaya keibubapaan menyumbang kepada peratusan varians yang berbeza kepada pola komunikasi keluarga orientasi perbualan dan orientasi konformiti.
Hubungan empati dan penghargaan kendiri ibubapa dengan gaya keibubapaan
Che Hasniza Che Noh
Jurnal Kemanusiaan , 2011,
Abstract: Artikel ini membincangkan aspek empati dan penghargaan kendiri di kalangan ibubapa dan hubungannya dengan gaya keibubapaan. Berdasarkan Model Keibubapaan Belsky, ciri ibubapa merupakan antara faktor yang mempengaruhi gaya keibubapaan. Dalam kajian ini, empati danpenghargaan kendiri telah dikenalpasti sebagai ciri ibubapa yang penting. Dalam konteks hubungan ibubapa dan anak, ibubapa yang empati akan lebih memahami anak-anak manakala penghargaan kendiri ibubapa akan mempengaruhi penilaian dan pandangan ibubapa terhadap anak-anak. Memahami dan menilai dengan positif adalah dua faktor penting untuk membolehkan ibubapa mendidik anak-anak dengan berkesan. Justeru, satu kajian telah dijalankan terhadap 300 ibu dan 277 bapa di Terengganu untuk melihat ciri ibubapa iaitu empati dan juga penghargaan kendiri. Sementara itu, kajian ini juga melibatkan anak responden yang berada di tingkatan empat bagi tujuan mendapatkan maklumat berkaitan gaya keibubapaan. Dapatan kajian menunjukkan majoriti responden di kalangan ibubapa mempunyai tahap empati dan penghargaan kendiri yangtinggi, serta mengamalkan gaya keibubapaan autoritatif dalam mendidik anak-anak.

Zhenghong Che,Zhengmei Che
International Journal of Higher Education , 2012, DOI: 10.5430/ijhe.v1n2p130
Abstract: China and South Korea are two neighboring countries and are both developing countries. Furthermore, the modern and contemporary higher education of these two countries originates from the middle and late 19th Century, so there are a lot of similarities between the two countries. However, although the origination period of modern and contemporary higher education of the two countries is almost similar, the developmental speed of higher education in these two countries is not totally the same due to the different strategic measures taken by the two countries in terms of developmental mode of higher education. Thus, study on differences between the higher education of these two countries and refer to the experience of South Korean higher education is of great and important realistic significance to improve higher education in China and promote and economic and social development. Through an analysis in the development history and educational system of higher education in South Korea, this article makes a comparison of the similarities and differences between China and South Korea in terms of the current condition and reform of their educational system so as to find out the gap between China and South Korea in terms of the higher education and explore a correct path for development of China higher education.

Ziyi He, Fuping Liu, Dewen Wang, Jialin Che, Jialin Che
Open Journal of Clinical Diagnostics (OJCD) , 2014, DOI: 10.4236/ojcd.2014.41008
Abstract: Objective: To investigate the relationship between the single ALT positive (ELSIA-HBV/HCV negative) and NAT-HBV/HCV on blood donor samples. Methods: 28710 samples were surveyed retrospectively from Dec. 2010 to Dec. 2011. ALT was detected by rate method, and the single ALT positive samples were detected by ELSIA-HBV/HCV and NAT-HBV/HCV. The relationship between the single ALT positive and NAT-HBV/HCV were analyzed. 21 samples, values in 40 U/L ≤ ALT ≤ 70 U/L, were selected at random from 2516 samples with single ALT positive, which were second detected by ELISA and NAT in the second donation. Results: 2516 (8.74%) single ALT positive samples (ELSIA-HBV/HCV negative) were found in 28710 donors. Among these samples, 8 (2.8/10000) positive were detected by NAT, including 5 HBV-DNA-positive and 3 HCV-RNA-positive. Obviously, positive rate of NAT from the donors whose ALT value ≤ 70 U/L were lower than those of ≥ 71 U/L (P < 0.01). 21 donors were investigated in the second donation in following 153 to 401 days, All samples were negative by ELISA-HBV/HCV and NAT-HBV/HCV. Conclusions: Donors with single ALT positive (value in 40 U/L-70 U/L) are not likely to become HBV/HCV virus carriers or HBV/HCV patients after half or one year. So it is to set ALT abandone threshlod to ≤ 70 U/L can ensure blood safety, and reduce blood abandone in our center.
Constraints on Jets and Luminosity Function of Gamma-ray Bursts Associated with Supernovae
H. Che
Physics , 1999,
Abstract: If Gamma-ray Bursts (GRBs) are generally associated with supernovae like 1998bw, a relatively wide intrinsic luminosity function is implied, which indicates the existence of a large amount of undetected dim bursts, and a much higher event-rate than is often assumed. If it is assumed that the intrinsic luminosity function of GRBs is a power-law: ${\phi (L)} \propto {L^{-\beta}}$ ($\beta > 0$, $L_{min} \leq L \leq L_{max}$), data from the BATSE 4B catalog can be used to constrain slope index $\beta$ and the dynamic range width Log ${L_{max}\over L_{min}}$. Using a K-S test comparison with the observational Log $N$ - Log $P$, we find constraints on the GRB fireball model, GRB jets, and the possible GRB contribution to cosmic gamma-ray background. We find the acceptable dynamic range for $10^2
