One of the main goals of small, medium and large farms is to improve the reproductive performance of rabbit does. Stocks of lower productivity can be improved by crossing with intensive breeds. A better nutritional status of both foetuses and suckling kits has a positive effect on their later productivity. Overfeeding young females before first mating can lead to conditions of fattiness. Using restricted feeding or higher fibre content in the feed and changing it for a higher level ad libitum feeding about one week prior to first mating leads to longer lifespan and higher productive level. Intensive reproductive rhythm creates a negative energy balance in does : they are unable to consume enough feed (energy) for the nutritional requirements of foetus and lactation, and therefore lose most of their fat reserves. Furthermore, primiparous does also expend energy because they are still growing. Under intensive conditions, the 42-d reproductive rhythm (re-mating 11 days after parturition) is recommended. Under extensive conditions, the 18 or 25-d mating interval with 35 to 42-d weaning could be suitable. On small farms, natural mating is favoured; on large farms AI is commonly employed. The main advantage of AI is the all-in, all-out system. Hormonal (PMSG) treatment is used with AI to increase receptivity on d 11. Frequent and high level PMSG use can lead to higher anti-PMSG antibody rates. Lower level (max. 20 IU) and less frequent PMSG injection or non-hormonal alternative methods (short dam-litter separation, changing nursing method or lighting programs) are recommended for this reason.

This study analyzes the U.S. case law which challenges the legal conclusions of the district court with respect to the applicability, and effect, of the doctrine of waiver and estoppel in addition to the doctrine of documentary cure. The impliations are as follows. First, the documentary cure requirement can not be interpreted to mean early enough to allow the beneficiary to cure and represent the documents before the presentment deadline or expiry date of letter of credit. The mere fact that the presentment period expired before the completion of bank's review and notification process does not compel any conclusion about whether the examiner spent a reasonable amount of time examining the documents. Indeed, the reasonable time requirement does not imply that banks examine a presentation out of order or hurry a decision based upon particular needs or desires of a beneficiary. Secondly, even if the doctrine of waiver can apply to letter of credit governed by the strict compliance standard, a one-time acceptance of discrepant documents by a bank does not waive the bank's right to insist upon conforming documents in all subsequent letter of credit transactions between the bank and beneficiary. Revised UCC Article 5 is highly persuasive on this point: waiver of discrepancies by issuer or an applicant in one or more presentation does not waive similar discrepancies in a future presentation. Neither the issuer nor the beneficiary can reasonably rely upon honor over past waivers as a basis for concluding that a future defective presentation will justify honor.

This study is focused on the review of buyer's remedy resulting from the breach of seller's duty in contracts for the international sale of goods focusing on UNCCIS, 1980 and the problems and suggestions of proper ideas for solving the problems. First problem on the buyer's remedy is related to the breach of seller's duty on del ivory of the contracted goods. When seller has failed to deliver the contracted goods to buyer within the stipulated periods, buyer can treat the contract as avoided and claim damages from seller. By the way, since UNCCIS does not provide any stipulation on the time of buyer's avoidance of the contract, buyer can delay the time of avoidance when the price of contracted goods is rising rapidly and enlarge the amount of damages, Since this stipulation is clearly unreasonable, proper solutions are required for UNCCIS. Second problem is related to the breach of seller's duty on deliver of goods which are of the quantity, quality and description required by the contract and which are contained or packged in the manner required by the contract. When seller has failed to deliver goods which are confirm with the contract, buyer may have one of the two rights of damages and the price reduction according to UNCCIS provided that he does not choose the avoidance. But, since the character and position of the price reduction as a buyer's remedy are not sufficient solutions, more detailed review on this point is required. Third, Seller's duty to provide documents is very important for overseas trade, but UNCCIS does not provide any specific buyer's remedy in comparison with the other remedy and also does not provide any stipulation on the Letter of Credit which have important roles for a device of setting payment in overseas trade. This means that trade customs and practice have not sufficiently reflected in UNCCIS. As the problems mentioned above may decrease the evaluation of buyer's remedy in UNCCIS and, furthermore, that of UNCCIS itself, proper solutions on these points are needed.

This paper examines 'Religion Class' in the scheme of the DDC. The major findings of the study are summerized as follows. 1. The first edition of DDC was published in 1876 in order to classify Amherst College Library collections. In spite of the continuous study and revision of the experts, the frameworks of the DDC systems are still kept unchanged. Only their subdivisions, reflecting those developments in the academic world, are developed and detailed more sophisticatedly. 2. The division of 200 does not function as generalities for all class of religion. Therefore, it is necessary to amend the division of 200 to serve generalities for all the religions of the world. 3. Standard subdivision for the christian religion and for the non-christian religion is different. So, the mnemonic nature has become weakened due to the dual standard subdivisions and the classification number becomes much longer and complicated. Therefore, one standard subdivision for all religions of the world is required. 4. Religion science was organized in late 19 C and developed continuously, but the DDC does not accomodate the religion science as a science. Accodingly, the DDC should be revised recognize religion science as a science not the christian science. 5. The deployment of classification scheme in Dewey's 200 is severely biased. That is to say, 9 division were assigned for christian religion, whereas only 1 division was assigned for non-christian religion. Therefore, an adjustment should be made to allocate subdivisions equally to all religions of the world. 6. General classification order of religion is prehistoric, primitive, ancient, modem and world religion in religion science. But, DDC does not accept this general classification order of religion, sticking to the biased expansion towards christianity. Therefore, DDC must adopt the general classification order of religion in the religion science. 7. Lastly, because of the limitation of decimal notation in DC, DDC does not accomodate new subject equally and classification number becomes longer. Therefore, centesimal expansion is proposed in order to make the classification number short, to enlarge its capacity of inclusion of new subject and to maintain consistency in the scheme.

본 논문은 컨볼루션 신경망(CNN)을 이용하여 폭발물 성분의 용량별로 분류할 때의 성능을 평가하는 연구이다. 기존의 폭발물 분류 방식 중에 IMS 증기 탐지기 방식은 폭발물의 농도가 사용자가 장비에서 설정한 임계치를 넘어야만 폭발물의 존재 여부를 판단한다. IMS 증기 탐지기는 폭발물이 존재하더라도 임계치를 넘지 않는 양이면 폭발물이 존재하지 않는다고 판단하는 문제가 있다. 따라서 폭발물 성분의 농도가 임계치를 넘지 않는 양일 때에도 폭발물 성분을 검출하는 방안이 필요하다. 이에 따라 본 논문에서는 폭발물 시계열 데이터를 Gramian Angular Field(GAF) 알고리즘으로 이미지화를 진행한 후 이미지와 영상처리뿐만 아니라 시계열 데이터 처리에도 뛰어난 성능을 보이는 딥러닝 모델인 컨볼루션 신경망(CNN)으로 직접 label을 설정해서 지도학습을 진행한 결과 폭발물 성분의 농도가 임계치를 넘지 않는 양일 때에도 폭발물 성분이 존재한다고 판단함과 동시에 폭발물 성분의 종류와 폭발물 성분의 농도의 양을 같이 판단할 수 있는지 성능평가를 진행했다.

Crossbred dairy does were fed a roughage diet (IVOMD 56%, N 2.27%) ad libitum, and supplemented with urea-molasses (3% W : W) (UM) at levels on an air dry basis of 1.5% or 3% of liveweight or an iso-energetic, iso-nitrogenous mixture of cottonseed meal and molasses (25 : 75 w : w) (CM). Eight does, four lower-producers and four higher-producers (1.9 and 2.5 kg/day respectively in week 7 of lactation) arranged in two Latin Squares, received each of the four diets for three weeks. Dry matter, digestible organic matter and N intakes were higher for high-producers and high levels of supplement but did not differ between nitrogen sources. Milk production was higher by high-producers; interactions were significant between level of supplement and production group and between level of supplement and N-source, with maximum production by high producers on high levels of CM. The main effects of level of supplement were only significant for production or composition. and total solids; N-source did not have significant effects on liveweight, milk production or composition. We conclude that does of moderate capacity for milk production, receiving a diet of two-thirds moderate quality roughage, one third urea-molasses, will not respond to increased level of supplementation or to replacement of urea with cottonseed meal.

A successful deployment of multimedia applications over wireless environments entails improving the quality of service (QoS), not only from a technical point of view, but also considering the quality of experience (QoE) from the final user's perception. Although objective QoE measure models avoid the difficulties of subjective surveys, subjective QoE assessments are essential to understand the way users evaluate the QoS. In this work, we study the effect of a wide range of parameters on the QoE of VVoIP applications in a real wireless scenario. Through a complete statistical analysis of users' ratings, we identify the following facts. Although the use of VVoIP in wireless networks does not yet represent an advantage for users, there are great expectations for all applications under study, and with greater popularity comes higher expectations. It is easier for respondents to identify good behavior than poor behavior. Whereas the respondents' frequency of Internet use does not impact on the scores, respondents' gender does. Finally, the most determining parameters of quality from a user's perspective were instability, video quality, voice distortion, usefulness, and graphical interface.

An add-on type output regulator is proposed in this paper. By an add-on controller we mean an additional controller which operates harmonically with a pre-designed one. The role of the add-on controller is to reject a sinusoidal disturbance of unknown magnitude and phase but with known frequency. Advantages of the proposed controller include that (1) it can be used only when the performance of disturbance rejection needs to be enhanced, (2) when it is turned on or off, unwanted transient can be avoided (i.e., bumpless transfer), (3) it is designed for perfect disturbance rejection not just for disturbance reduction, (4) ability for perfect rejection is preserved even with uncertain plant model. This design may be promising for optical disc drive (ODD) systems in which disc eccentricity results in a sinusoidal disturbance. For ODD systems, the sensitivity function obtained by the pre-designed controller, which may have been designed by the lead-lag, $H_{\infty}$, or DOB (disturbance observer) technique, does not change much with the add-on controller except at the frequency of the disturbance. Since the add-on controller does the job of rejecting major eccentricity disturbance, the gain of the pre-designed controller does not have to be too high.

To verify the existing theory, non-propagating crack(NPC) does not exist in Ti which fulfills the good conditions for being of NPC, NPC detection in Ti was tried out. Also, the conception of fatigue limit in Ti and a main cause for NPC being were inquired. NPC was detected in both sharp notch root ( $\rho$=0.02mm) and micro pit (diameter = 0.25mm) which held fast to the end under stressing of fatigue limit. Therefore, the existing theory was identified as mistake. But, NPC can not be detected in smooth specimen. This fact would be due to the presumption that NPC is very small or crack does not initiate in smooth specimen. Anyway, the fatigue limit of Ti does not correspond to critical stress of crack initiation but correspond to critical stress of NPC growth. Measurement on the COD of NPC in Ti showed that the crack tip was closed even under the peak stress level at fatigue limit. But, after stress relieving annealing crack tip was opened. Consequently, compressive residual stress which is induced around the crack tip is considered to be the factor causing the NPC being.

The S.G. Policy form contains the words "the good ship or vessel called the.....". The words "good ship" mean that the ship is deemed to be seaworthy at the commencement of the voyage and this was very necessary in the day when a separate policy was issued for each voyage. In fact the warranty do seaworthiness still applies to all voyage policies. Nevertheless, the law does not apply an absolute warranty of seaworthiness to a time policy, so a ship is not required to be seaworthy at the time the hull policy is effected. The implied warranty of seaworthiness does not extend to good, for the underwriter is not responsible for their condition, apart fro the action of the perils insured against. The implied warranty of seaworthiness is limited to the vessel herself, and does not extend to a lighter or other craft used to convey the goods to the ship. The underwriters waive any breach of the implied warranties of the seaworthiness of the ship and fitness of the ship to carry the subject-matter insured to destination, unless the assured or their servants are privy to such unseaworthiness of unfitness.
