Objective: An experiment was conducted to examine the effect of dietary supplementation of dried and ground foliage of black gram (Vigna mungo L.) on feed intake and utilization, and production performance of crossbred lactating cows. Methods: Eighteen lactating crossbred (Bos taurus${\times}$Bos indicus) cows (body weight $330.93{\pm}10.82kg$) at their second and mid lactation (milk yield $6.77{\pm}0.54kg/d$) were randomly divided into three groups of six each in a completely randomized block design. Three supplements were formulated by quantitatively replacing 0, 50, and 100 per cent of dietary wheat bran of concentrate mixture with dried and ground foliage of black gram. The designated supplement was fed to each group with basal diet of rice straw (ad libitum) to meet the requirements for maintenance and milk production. Daily feed intake and milk yield was recorded. A digestion trial was conducted to determine the total tract digestibility of various nutrients. Results: The daily feed intake was increased (p<0.05) with the supplementation of black gram foliage. Although the digestibility of dry matter, organic matter, crude protein, and ether extract did not vary (p>0.05), the fibre digestibility was increased (p<0.05), which ultimately improved (p<0.05) the total digestible nutrients content of composite diet. Although, the average milk yield (kg/animal/d) and composition did not differ (p>0.05) among the groups, milk yield was increased by 10 per cent with total replacement of wheat bran in concentrate mixture with of black gram foliage. The economics of milk production calculated as feed cost per kg milk yield (INR 10.61 vs 7.98) was reduced by complete replacement of wheat bran with black gram foliage. Conclusion: Black gram foliage could be used as complete replacement for wheat bran in concentrate mixture of dairy cows in formulating least cost ration for economic milk production in small holders' animal production.

This paper is intended on providing solutions for overcoming constraints to the transmission of the Important Intangible Cultural Properties related to dance successors. For accommodating this approach, six career dancers, from the Dance Society of the Important Intangible Cultural Properties, were invited as the research participants for this study. The In-Depth Interviews and the classification analysis are used as a way of structuring and understanding my observations about these tasks. These interviews have also been verified by an expert group. In conclusion, this study identifies numerous obstacles which can restrict the transmission of the Important Intangible Cultural Properties are as follows; first, the dance successors are constrained by personal reasons such as physical strength and mutual understanding at home; second, the dance successors are affected by the structural constraint of programs such as required time for the completion of training, efficiency of the training program and the educational environment; third, the dance successors are constrained by personal relations such as the relationship between themselves, or between the dance successors and holders of Important Intangible Cultural Properties. Suggested solutions for overcoming the constraints to training programs are; building small sized training centers throughout the country; making training time realistic for individuals; and making programs to train the dancers as well as making it sociable.

High dose rate (HDR) brachytherapy in the treatment of cervix carcinoma has become popular, because it eliminated many of the problems with conventional brachytherapy. In order to improve clinical effectiveness with HDR brachytherapy, dose calculation algorithm, optimization procedures, and image registrations should be verified by comparing the dose distributions from a planning computer and those from a humanoid phantom irradiated. Therefore, the humanoid phantom should be designed such that the dose distributions could be quantitatively evaluated by utilizing the dosimeters with high spatial resolution. Therefore, the small size of thermoluminescent dosimeter (TLD) chips with the dimension of 1/8" and film dosimetry with spatial resolution of <1mm used to measure the radiation dosages in the phantom. The humanoid phantom called a pelvic phantom is made of water and tissue-equivalent acrylic plates. In order to firmly hold the HDR applicators in the water phantom, the applicators are inserted into the grooves of the applicator supporters. The dose distributions around the applicators, such as Point A and B, can be measured by placing a series of TLD chips (TLD-to- TLD distance: 5mm) in three TLD holders, and placing three verification films in orthogonal planes.

The transfer of R&D performance is the technology transfer in a narrow sense. This study aimed at fanning the effective managerial systems of the transfer of the academic entrepreneur's R&D performance. For this purpose, this study analysed the characteristics and success factors of R&D performance transfer based on the theory of project life cycle. This research classified the life cycle of academic entrepreneurs' R&D projects into six stages. And the risks associated with the transfer process was categorized using the case study about the establishing processes the mineral-related small finns. Especially, the risk of the technology transfer was investigated by the R&D project implementation stages. Based on this results, this paper suggested the strategic system such as the marketing-oriented thinking, the clear-cut statement of the role among the stake-holders of the R&D and commercialization processes, the dynamic system of the academic entrepreneurs' leadership, the formation of the transfer management system, and the usage of project risk management techniques.

This study was conducted to investigate the effects of impact conditions on the acoustic characteristics of a watermelon. The study was crucial to develop a device for nondestructive internal quality evaluation of a watermelon by an acoustic impulse response method. An impact device was constructed with a pendulum to hit the watermelon, a microphone to detect the acoustic impulse responses, and a digital oscilloscope and computer to store and analyze the data. The selected samples were Guemcheon cultivar watermelons(Citrulus Vulgaris Schrad) harvested on Oct. 20,1998. Sixty watermelons were tested on flour different types of sample holders, with four kinds of ball made of different materials, at four bevels of the angular position of the pendulum and distance from the watermelon to the microphone. Since the magnitudes of frequencies obtained by hitting with the steel and rubber ball were relatively small at the bandwidths of above 500 Hz, it was shown that the steel and rubber ball were not suitable far a hitting ball in the pendulum to get informations on internal quality of the watermelon. In case of using broth of the wood and acryl ball, almost the same and good acoustic responses were shown on the wide range of frequency bandwidth. Therefore, it seemed that the acryl ball was more suitable to the test than the wood ball in considering its mechanical properties. The acoustic characteristics of the watermelon were not shown a significant difference between the types of sample holder. The amplitudes of the acoustic signals and the magnitudes of frequencies from the whole samples increased with increase of the angular position of pendulum and with decrease of the distance from the watermelon to the microphone. However, the resonance resonance of the sample were almost the same regardless of the angular positions and the distances.

This study analyzed the effects of TLO's organization size, expertise, and economic compensation on technology transfer performance using the panel data of Government-Funded Research Institutes in 2013-2016. First, the size of TLO personnel and budget have a positive effect on the technology transfer performance. However, in the case of TLO manpower, the statistical significance of the effect on the number of technology transfers was only 90%, and it did not affect royalty. Second, TLO expertise has a strong impact on technology transfer performance. It shows that the number of professional license holders, such as patent attorney or a technology valuer, has a statistically significant effect on the increase of the technology transfer number and the royalty under the 99% confidence level. However, unlike expected, the size of the Ph.D. did not seem to have any effect on technology transfer performance. Finally, the economic compensation for TLO does not affect both the number of technology transfers and the royalty. It does not seem to work as an appropriate incentive system, because the absolute size of the compensation is too small. The results of the above analysis suggest that it is important to secure expertise in order for the TLO organization to play a substantial role, and it is necessary to improve the economic compensation system to attract TLOs to technology transfer.

High dose rate (HDR) brachytherapy for treating a cervix carcinoma has become popular, because it eliminates many of the problems associated with conventional brachytherapy. In order to improve the clinical effectiveness with HDR brachytherapy, a dose calculation algorithm, optimization procedures, and image registrations need to be verified by comparing the dose distributions from a planning computer and those from a phantom. In this study, the phantom was fabricated in order to verify the absolute doses and the relative dose distributions. The measured doses from the phantom were then compared with the treatment planning system for the dose verification. The phantom needs to be designed such that the dose distributions can be quantitatively evaluated by utilizing the dosimeters with a high spatial resolution. Therefore, the small size of the thermoluminescent dosimeter (TLD) chips with a dimension of <1/8"and film dosimetry with a spatial resolution of <1mm used to measure the radiation dosages in the phantom. The phantom called a pelvic phantom was made from water and the tissue-equivalent acrylic plates. In order to firmly hold the HDR applicators in the water phantom, the applicators were inserted into the grooves of the applicator holder. The dose distributions around the applicators, such as Point A and B, were measured by placing a series of TLD chips (TLD-to-TLD distance: 5mm) in the three TLD holders, and placing three verification films in the orthogonal planes. This study used a Nucletron Plato treatment planning system and a Microselectron Ir-192 source unit. The results showed good agreement between the treatment plan and measurement. The comparisons of the absolute dose showed agreement within $\pm$4.0 % of the dose at point A and B, and the bladder and rectum point. In addition, the relative dose distributions by film dosimetry and those calculated by the planning computer show good agreement. This pelvic phantom could be a useful to verify the dose calculation algorithm and the accuracy of the image localization algorithm in the high dose rate (HDR) planning computer. The dose verification with film dosimetry and TLD as quality assurance (QA) tools are currently being undertaken in the Catholic University, Seoul, Korea.
