Food consumption and conversion efficiency of new bivoltine hybrids (CSR2$\times$CSR4 and CSR2$\times$CSR5) were studied under restricted feeding levels (10, 20 and 30% less quantity of mulberry leaves). The data were compared with a control fed with standard quantum of feed as per the recommendation. The nutritional indices parameters i. e. ingests, digesta, approximate digestibility (%) and reference ratio were recorded higher in control batches compared to less feed batches while nutritional efficiency parameters i. e., ECI and ECD to cocoon and shell were recorded significantly higher in restricted feeding level batches. This increase is attributed due to the physiological adaptation under nutritional stress condition.

Twelve pure silkworm lines identified based in higher G.C.A values from a line${\times}$Tecter crossing programme, were crossed with twelve breeds showing cocoon shell ratio>22% and hybrids prepared, evaluated in a Multiple index method. Seven hydrids showing average index value>50 in all the 10 economic characters were seclcted and evaluated in the laboratory. However, two hybrids viz., A3${\times}$935E and A3${\times}$916B were finally selected based on the superiority of the breeds in one day shorter larval duration and with and with higher reeling characters compared to control KA${\times}$NB4D2. The breeding procedure involed in evolution hybrids are discussed.

이 연구는 자연발생고혈압쥐(SHR)의 혈압, 골격근에서의 혈관생성 및 혈관내피세포성장인자 발현(VEGF)에 미치는 지구성운동의 효과를 조사하였다. 5주령 SHR와 WKY는 무작위로 정상혈압군(WKY, Wistar-Kyoto rat, n=9), 고혈압통제군(SHR-C, SHR Control, n=9) 및 고혈압운동군(SHR-E, SHR Exercise, n=9)으로 각각 분류하였고, 지구성운동은 트레드밀을 이용하였다(12-20 m/min, 0% grade, 60 min/day, 5 days/wk, 16 wk). 수축기혈압은 지구성운동에 의해 효과적으로 감소되었다(SHR-E vs. SHR-C, $p$ <0.05). 골격근의 모세혈관밀도와 VEGF 단백발현은 고혈압통제군(SHR-C)이 정상혈압군(WKY)보다 모두 감소되었으나, 지구성운동(SHR-E)이 고혈압통제군(SHR-C)에 비해 모두 증가되었다. 이러한 결과들은 지구력운동 트레이닝이 SHR 골격근의 VEGF 단백발현의 증가를 통해 모세혈관밀도를 향상시키고, 이러한 모세혈관밀도의 향상이 SHR의 혈압상승을 억제할 수 있다는 것을 의미한다.

eLearning can be defined as an approach to teaching and teaming that utilises Internet technologies to communicate and collaborate in an educational context. This includes technology that supplements traditional classroom training with web-based components and learning environments where the educational process is experienced online. The use of hypertext as an educational tool has a very rich history. The advent of the internet and one of its major application, the world wide web (WWW), has given a tremendous boost to the theory and practice of hypermedia systems for educational purposes. However, the web suffers from an inability to satisfy the heterogeneous needs of a large number of users. For example, web-based courses present the same static teaming material to students with widely differing knowledge of the subject. Adaptive hypermedia techniques can be used to improve the adaptability of eLearning. In this paper we report an approach to the design a unified implementation framework suitable for web-based eLearning that accommodates the three main dimensions of hypermedia adaptation: content, navigation, and presentation. The framework externalises the adaptation strategies using XML notation. The separation of the adaptation strategies from the source code of the eLearning software enables a system using the framework to quickly implement a variety of adaptation strategies. This work is a part of our more general ongoing work on the design of a framework for adaptive content delivery. parts of the framework discussed in this paper have been imulemented in a commercial eLearning engine.

The recent development of IT, consolidation of communication and multimedia technology have brought enormous changes in many organizations. Theses changes are enabling the new educational opportunities such as distance teaming and virtual class room. Recently, e-Learning has grown rapidly in business training field, In the context of companies, e-Learning has merits in terms of access convenience, costs reduction self-directed learning, reciprocity, and flexibility. In this regard, the primary purpose of this study is to investigate which factors of e-Learning influence the effectiveness of education and transfer of loaming in business organizations. Based on the prior studies of the education and business training field, research model and research hypotheses were developed. Factors studied in this paper were as follows: 1) learners' characteristics, 2) organizational support and 3) system environments. The results of our study are as follows. (1) Motivation perceived usefulness in Learner factors had an significant influence on both learning effectiveness and transfer of teaming, whereas Ability, expectation had an influence on transfer of teaming. (2) Support from peer, support from supervisor in Organization factors had an significant influence on both Loaming effectiveness and transfer of teaming, whereas support from organization had influence on learning effectiveness. (3) Appropriate contents in system circumstance had an significant influence on both teaming effectiveness and transfer of teaming, whereas interface design had an influence on learning effectiveness.

The present study was designed to investigate the effect of altruistic TV viewing and verbal training on the altruistic behavior of preschoolers. The subjects of this study were a total of 56 boys and 57 girls from a kindergarten in Kwachon, Kyung-gi do. The subjects were assigned to one of three conditions: in the first condition subjects were shown video tapes designed to portray prosocial themes (TV modeling group) ; in the second condition subjects saw the video tapes in addition to verbal training (TV modeling plus verbal training group); in the third condition subjects received neither TV modeling nor verbal training (control group). Statistical analysis was by ANOVA and $Scherr\acute{e}$ test. Significant differences were found in altruistic behavior between the TV modeling and the TV modeling with verbal training groups.

This paper presents the educational methodology shipboard training methods of Maritime Colleges in U.S.A. and the fields of engagement in business of the graduates from them. There are two Maritime Academies, i.e. U.S. Merchant Marine Academy (USMMA) and U.S. Coast Guard Academy, which are supported by federal government and six Maritime Colleges operated by each State. Maritime Administration (MARAD) in the Department of Transportation (DOT) supports the training of merchant marine officers and crew members with a focus on safety in U.S. waterborne commerce. The shipboard training methods are not unique, but have various process. One is continuous sea term training onboard during sophomore (100 days) and junior year (200 days) in case of USMMA, the other is summer sea term training onboard every three months during freshman, sophomore and junior years in case of SUNY Maritime College. They offer also one month ship simulator training ashore. The employment status for the 1999 year graduates from USMMA shows 43 percent in the field of maritime afloat, 34 percent of maritime ashore, 22 percent of active duty military and 1 percent of others.

A Language model with neural networks commonly trained with likelihood loss. Such that the model can learn the sequence of human text. State-of-the-art results achieved in various language generation tasks, e.g., text summarization, dialogue response generation, and text generation, by utilizing the language model's next token output probabilities. Monotonous and boring outputs are a well-known problem of this model, yet only a few solutions proposed to address this problem. Several decoding techniques proposed to suppress repetitive tokens. Unlikelihood training approached this problem by penalizing candidate tokens probabilities if the tokens already seen in previous steps. While the method successfully showed a less repetitive generated token, the method has a large memory consumption because of the training need a big vocabulary size. We effectively reduced memory footprint by encoding words as sequences of subword units. Finally, we report competitive results with token level unlikelihood training in several automatic evaluations compared to the previous work.

TBM의 운전 전문인력은 세계적으로 부족한 상황이며 신규 인력의 시공경험 부족은 각종 시공리스크 발생 시 대응능력 저하를 가져올 수 있다. TBM 시공품질이 TBM 운전자의 숙련도와 경험에 크게 좌우되는 점과 숙련인력 부족에 의한 생산성 저하, 숙련도 저하에 의한 안전성 저하는 TBM산업에서의 자주 거론되는 문제점이다. 이를 위해 국외의 몇 개 업체와 기관에서 시뮬레이터를 개발하였고 국내에서도 시뮬레이터 개발이 이루어지고 있다. 국제터널협회에서는 강의실 교육, e-learning, 시뮬레이터 교육 및 현장 실습을 포함하는 포괄적인 교육을 계획하고 있다. 국내외 진행상황으로 볼 때, TBM 운전자 교육 및 인증 또는 라이센스를 통한 공식적인 교육 인정은 멀지 않은 미래에 표준이 될 것으로 예상된다.
