The purpose of this study is to measure the impact of motivation on academic achievement and satisfaction of adult learners in an e-Learning environment, and to come up with strategies to improve the effectiveness of e-Learning for adult learners. In order to find answer, devices were developed, tested for validity and reliability, and use for testing variables for 289 adult learners. To measure the impact of achievement motivation on learning in job training, a multiple regression analysis was performed. The analysis results show that achievement motivation has an impact on academic achievement with significance level .001, but does not have an impact on a learner's satisfaction. Further analyses on the subcategories of achievement motivation show that individual-oriented motivation affects achievement with significance level of .001, while social-oriented motivation does not. From this finding, some strategies to boost individual-oriented motivation are suggested to enhance effectiveness of job training in e-Learning environment. Further strategies to boost individual-oriented motivation should be developed by studying various aspects of e-Learning such as learning environments, learning culture, learning modes and methods, and evaluation.

Manifestation of heterotic genetic interaction was studied in different hybrids made between multivoltine recurrent backcross (RBL)/congenic lines (Con. L) during unfavourable season when temperature and relative humidity are > $30^{\circ}C$ and 86%, respectively. A few number of silkworm race or strain or breed like Nistari (N ＋ p or Np) can sustain the temperature above 3$0^{\circ}C$ and RH above 86%. The present heterosis study screened a hybrid i.e., CB$_{5}$Lm5RBL1M$_{6}$DPC-LmE$^1$RBL and its reciprocal provided heterobeltiotic effect on survival by number and pupation rate at a magnitude of 20% (p < 0.01) and yield by weight of 10% (p < 0.01). Beside all the hybrids expressed heterosis over check - Nistari (N ＋ p) with better quality silk. Therefore, aforesaid hybrid may be useful for utilization at commercial level during adverse seasons of West Bengal.gal.

Phytoecdysteroids with moulting hormone (MH) activity induce different responses in silkworms when used on different day of final instar, which can be manipulated for maximum benefit like early and uniform spinning behaviour, reducing crop loss and to increase cocoon yield. The results showed that application of this hormone on seed crop viz., CSR2, CSR4 and BL44 and BL67 in early stage of 5$^{th}$ instar i.e., at 72 hrs and 96 hrs though induced early and uniform spinning behaviour, there was an adverse effect by 9-36% on the economic characters like cocoon yield, cocoon weight, cocoon shell weight and also on fecundity etc. Application of this hormone in late stage of $5^th$ instar i.e., at the onset of spinning showed non-significant variations in some of the characters like cocoon weight, cocoon shell weight, cocoon shell ratio and fecundity. The physiological implications of phytoecdysteroid in hastening the maturation events and synchronization of spinning activities in different breeds are discussed.

To evolve silkworm hybrids with higher survival and better cocoon characters, evaluation of semen hybrids in the laboratory (short-listed out of 143 hybrids) resulted in the identification of two promising hybrids, A3${\tines}$935 E (HSP1) and A3${\tines}$916 B (HSP2). The hybrids were evaluated at three different Regional Sericultural Research Stations of Central Silk Board during 1997-1998 and also tested with the farmers along with two control hybrids, KAxNB4D2 and PMxNB4D2. Evaluation of the hybrids indicated that these hybrids can be reared in all the seasons, especially during summer season. These hybrids show shorter larval duration (22 days 17 hrs against 23 days in control KAxNB4D2 and better cocoon characters as compared to the crossed breeds PM ${\tines}$NB4D2).

Background: Previous studies have investigated technology-aided needling training systems for acupuncture on phantom models using various measurement techniques. In this study, we developed and validated a vision-based needling training system (noncontact measurement) and compared its training effectiveness with that of the traditional training method. Methods: Needle displacements during manipulation were analyzed using OpenCV to derive three parameters, i.e., needle insertion speed, needle insertion angle (needle tip direction), and needle insertion length. The system was validated in a laboratory setting and a needling training course. The performances of the novices (students) before and after training were compared with the experts. The technology-aided training method was also compared with the traditional training method. Results: Before the training, a significant difference in needle insertion speed was found between experts and novices. After the training, the novices approached the speed of the experts. Both training methods could improve the insertion speed of the novices after 10 training sessions. However, the technology-aided training group already showed improvement after five training sessions. Students and teachers showed positive attitudes toward the system. Conclusion: The results suggest that the technology-aided method using computer vision has similar training effectiveness to the traditional one and can potentially be used to speed up needling training.

Objectives : The Levator Ani Muscles Training(LAMT) is one of the well known very effective prevention and treatment method of some specific diseases in the anal organs, digestion system, urinary organs and genital organs, which means LAMT could be considered as an independent exercise. Methods : Chinese databases were searched and found one good source named CNKI(China National Knowledge Infrastructure) where there were downloaded 154 articles, out of which were finally selected 82 used for the introduction of the historical background, health-effectiveness, working mechanism, training methods, etc. Results : LAMT as an independent exercise, is considered very effective for the prevention of diseases in the anal organs, e.g. hemorrhoids, anal fissure, rectal prolapse; urinary organs, e.g. urinary incontinence, frequent micturition; digestion system, e.g. visceroptosis, diarrhea, chronic enteritis; genital organs, e.g. prostatitis, impotence, premature ejaculation, feminine vaginal relaxation, sexual indifference, etc. It is also told LAMT is effective for coronary heart disease, hyperyension and varicose veins of lower extremity to a certain degree. LAMT is also very similar to the Kegel exercise in couple of aspects. They are equally effective for the urinary incontinence and impotence. Conclusions : LAMT as an independent exercise has developed and become more and more health-effective, especially through the combination with the Qigong exercise, and thus many training methods have been introduced. There are not many scientific research and development with very limited accomplishments even in China. It is strongly required to strengthen the research and development activities so that LAMT will become one of the very effective natural healing soonest possible.

This paper presents an operator training simulator for power system restoration against massive black-out. The system is designed especially focused on the generality and convenient setting up for initial condition of simulation. The former is accomplished by using power flow calculation methodology, and PSS/E data is used to define the initial situation. The proposed simulator consists of three major components - the power flow(PF) module, data conversion(COW) module and GU subsystem. PF module calculates power flow, and then checks overvoltage of buses and overflow of lines. COW module composes an Y-Bus array and a data base at each restoration action. The initial Y-Bus array is constructed from PSS/E data. The user friendly GUI subsystem is developed including graphic editor and built-in operation manual. As a result, the maximum processing time for one step operation is 15 seconds, which is adequate for training purpose. Comparison with PSS/E simulation proves the accuracy and reliability of the training system.
