Currently, many enterprises are trying to allocate the investment costs and risks through collaboration, and strengthen their competitiveness by sharing their resources and gains. Intercorporate sharing economy, a type of intercorporate collaboration, refers to the economic activity to share the idle resources of enterprises and enhance their efficiency. For a successful intercorporate economy with the participation of various stakeholders, there is a need to establish the clear allocation method of gains. Accordingly, this study suggested three methods-the MST method that can apply transaction cost incurred when forming a coalition for sharing economy; the average of transaction cost incurred by each participant, and the Shapley Value application method for the transaction cost incurred between the participants. In addition, this study also suggested gain allocation methods such as the "Equal distribution of gain" method, a gain allocation method based on the Cooperative Game Theory, the the "Proportional distribution of gain" method, and the Shapley Value method that takes in consideration the transaction costs.

The objective of this research was to evaluate the effects of two different feeding systems on blood metabolites in Holstein heifers and analyze the economic impacts of the feeding systems. The following two experiments were conducted to investigate the effects of feeding system on blood metabolite changes in Holstein heifers and analyze the economic impacts of the two systems. In experiment 1, the effects of two different feeding systems on cortisol, progesterone, and estradiol in Holstein heifers were examined. In experiment 2, the effects of two different feeding systems on the body weights of Holstein heifers and profitability of the two feeding systems were studied. Results showed that the pasture-raised heifers showed significantly decrease in the levels of blood cortisol (p<0.05) and increases in the levels of progesterone and estradiol (p>0.05) when compared with heifers raised in indoor feeding system. The average daily gain was significantly higher (p<0.05) in indoor-raised heifers (0.73 kg/day) as compared to pasture-raised heifers (0.58 kg/day). Also, 25.2% more profits were obtained from the pasture feeding system as compared to the indoor feeding system. These results together would be useful in the investigation of feeding system and growth performance in dairy cattle.

Data pertaining to first lactation records of 316 Murrah buffaloes, progeny of 47 sires, maintained at NDRI Farm for a period of 18 years were analysed to construct selection indices and to examine their robustness by changing the relative economic values of different economic traits. A total of 120 selection indices were constructed for three sets of relative economic values ( 40 for each set) considering different combinations of seven first lactation traits viz. age at first calving (AFC), first lactation 305 day or less milk yield (FLMY), first lactation length (FLL), first calving interval (FCI), milk yield per day of first lactation length (MY/FLL), milk yield per day of first calving interval (MY/FCI) and milk yield per day age at second calving (MY/ASC). The three sets of relative economic values were based on economic values of different traits, 1% standard deviation of different traits and regression of different traits on FLMY. The 'optimum' indices for the first two sets had five traits each namely AFC, FLMY, FLL, FCI and MY/ASC giving improvement in aggregate genotype of Rupees 269.11 and Rs. 174.88, respectively. The accuracy of selection from both indices was 70.79 and 69.39%, respectively. The 'best' selection index from the third set of data again had five traits (AFC, FLMY, FLL, FCI and MY/FLL) giving genetic gain of Rs. 124.16 and accuracy of selection of 71.81%. The critcal levels or break-even points for FLMY for varying levels of AFC and FCI estimated from the "optimum index" suggested the need of enhancement of present production level of the herd or reduction of AFC or FCI. It was concluded that economic values of various first lactation traits were the most appropriate to construct selection indices as compared to other criteria of assigning relative economic weights in Murrah buffaloes.

The purpose of this paper is to estimate the economic value of Multi-functionality Roles including landscape and so on, which traditional stone fences in Korea possess, using Dichotomous Choice Contingent Valuation Method (DC-CVM). The stone fences is life cultural heritance of regional residents. It has functions like Development of Favorable Landscapes, Maintenance of Cultural Heritage, and Recreation/Relaxation. Expectation from regional visitors shows that the existence and inheritance value of the stone wall is higher then we expected. According to the research that we had done from the people that had agreed to contribute the stone wall. moreover the public commercial value of regional tradition stone was not only 2,900 billion won but also it will increase an economic gain in every year. Therefore, preserving the stone wall that has Multi-functional Roles and values can lead to huge economic value in the future. But farmhouses in the stone wall conservation area are being supported 9 billion won in every year. This is only 0.03% of the income that farmhouse earns per year. Thus, stone wall preservation policy and plan can raise green-tour commercial value of inland area as a long-term inside measurement. Those will have to be propelled continuously.

In order to make the high quality Korean cattle, it has been identified the gene which influence to various economic characters. In this paper, we introduce Restricted Partition Method for gene-gene interaction analysis. Further, economic traits, longissimus muscle dorsi area (LMA), carcass cold weight (CWT) and average daily gain (ADG) are applied with Restricted Partition Method (RPM). The SNP (19_1)$^*$SNP (28_2) was selected and was best marker on Single nucleotide polymorphisms (SNPs). It also influenced SNP (19_1)$^*$SNP (28_2) was an very important marker for economic character and to make the thing know it became.

The purpose of this paper is to estimate economic value of multi-functionality roles including landscape and so on, which grassland in Jeju possesses, using Dichotomous Choice Contingent Valuation Method (DC-CVM). Grassland is life cultural heritance of regional residents in Jeju. It has functions like development of favorable landscapes, maintenance of cultural heritage, and recreation/relaxation. Expectation from regional visitors shows that the existence and inheritance value of grassland is higher than we expected. According to the research that we had done from the people that had agreed to contribute grassland. moreover the public commercial value of grassland was not only $397{\sim}419$ billion won but also it will increase an economic gain in every year in Jeju. Therefore, preserving grassland that has multi-functional roles and values can lead to huge economic value in the future in Jeju. Moreover, farm households which are located in the grassland conservation area would be supported $15{\sim}31$ billion won in every year for grassland conservation but it is only $4{\sim}8%$ of the economic value of grassland i.e. $3,971{\sim}4190$ billion won. Thus, grassland preservation policy and plan can raise green-tour commercial value of Jeju area as a long-term inside measurement. Those will have to be propelled continuously.

A study was undertaken to investigate the effect of feeding early weaning diets based on different vegetable protein sources fed to Afghani lambs. Three isonitrogenous and isocaloric complete formula diets viz., A, B and C were prepared having cottonseed meal, soybean meal and canola meal; respectively as major source of protein. Eighteen 30-35 days old Afghani male lambs were randomly allotted to three experimental diets. Lambs were fed individually twice a day for a period of 60 days. Daily feed intake and weekly weight gain was recorded. Results indicated that weight gain was significantly(p<0.05) higher(282 g/lamb/day) in lambs fed diet B as compared to lamvs fed on diets A(231 g/lamb/day) and C(242 g/lamb/day). No significant difference was found in feed intake among the diets. Significant difference(p<0.05) were noticed in feed efficiency in lambs fed on diets A(6.88), B(5.41) and C(6.17).The economic efficiency was observed to be the best on diet B as compared to diets A and C. It was concluded that Afghani lambs(30-35 days) can be reared on early weaning diets and soybean meal was found comparatively better protein source for early weaning diet.

This study was conducted to investigate the effect of fat on gain percent, yield and sensory properties of soybean curd by partial or whole replacement of soybean with defatted soy flour, The results obtained were as follows ; 1. Gain percent and yield of soybean curds were decreased as the fat content of materials decreased. 2. In sensory evaluation, the mean scores for appearance (color and smoothness), texture and acceptability significantly decreased as the ratio of defatted soy flour to soybean increased. However, when the defatted soy flour replaced 20 and 30％ of the soybean, the mean acceptability scores did not differ significantly with whole soybean curd. From the above data, if defatted soy flour will be used for making soybean curds with the aspect of sensory and economic reasons, 25％ level of replacement can be recommended.

Recycled pulp therefore play a very important role in the paper industry today as a substitute for virgin pulp. In many countries of the world, the paper industry could not exist as it does without recycled pulp. Because, this is mainly due to economic reasons. Particularly in our country, the additional reason is the scarcity of native pulpwood resources. Therefore, the use of recycled pulp is very important. This study was aimed to apply recycled pulp to textbook paper. So we made a paper containing 30% recycled pulp and investigated about print quality, such as color reproduction, trapping, contrast, dot gain, gloss and print through. The results showed that is similar to existing textbook papers.
