A study on the development of material for a light weight partition wall using material of gypsum and waste paper is be considered to improve workability, setting time, properties of strength by use of $\beta$-Gypsum for controling setting time. According th the experiments, as quantity of gypsum in binder increase, workability and strength of specimens deteriorate. Appropriate quantity of $\beta$-Gypsum was 3~6% of binder and When it was used more than 10%, setting time was so fast. When additive quantity of waste paper has increased to 1%, flexural strength decreased to some 8~12% and density decreased abort 3% in comparison with otherwise specimen.

The results from quality measurements of Angake sauce are as followings. The content of solids increased depending on the quantity of added starch. The pH increased with the quantity of added starch, but did not show significant changes. The viscosity increased as the quantity of added starch increased. The preference was the highest for the group with 6% added starch, and preference was shown in order of 6% > 7% > 5% > 8% > 4%. The addition of 6~7% starch to Angake sauce is considered to be most appropriate.

In this paper, the proper quantity of conditioning rounds has been studied using the statistical analysis on the basis of the acceptance test data of K676 and K677 propelling charge for K9 self propelled howitzer. In general, the muzzle velocity of the initial rounds tends to be a little lower than that of the succeeding rounds. The latter rounds are likely to have the constant velocities after firing the appropriate conditioning rounds. The main cause of velocity difference was proved to be the proper quantity of conditioning rounds by doing the correlation analysis among the initial tube temperature, the tube life and the quantity of conditioning rounds. The result of paired t-test shows that two rounds of conditioning projectiles are proved to be enough to maintain the constant velocity in the case of the acceptance test of K676 and K677 propelling charge.

Photovoltaic(PV) system is one of power generation systems. Solar light in PV system is like the fuel of the car. The quantity of electricity generation, therefore, is fully dependent on the available quantity of solar light on the system of each site. If a utility can predict the solar power generation on a planned site, it may be possible to set up an appropriate PV system there. It may be also possible to objectively evaluate the performances of existing solar systems. Based on the theories of astronomy and meteorology, in this paper, Perez model is simulated to estimate the available quantity of solar lights on the prevailed photovoltaic systems. Consequently the conditions for optimal power generation of each PV system can be analyzed. And the maximum quantity of power generation of each system can be also estimated by applying assumed efficiency of PV system. Perez model is simulated in this paper, and the result is compared with the data of the same model of Meteonorm. Simulated site is Daejeon, Korea with typical meteorological year(TMY) data of 1991~2010.

The concept of non-conformity is stipulated at Art. 35, CISG. According to the Art. 35, there is no directly stipulated concept of non-conformity. But Art. 35 said that the Seller must deliver goods which are of the quantity, quality and description required by the contract and which are contained or packaged in the manner required by the contract. Accordingly, the concept of non-conformity contains the conformity of quality, quantity, description, delivery of different goods and documents. Art. 39 does not specify the form of notice required. So parties can require a particular form by agreement. If there is no agreed form of notice, buyer' s notice must be sent by means appropriate in the circumstances. And Art. 39 states that the required notice of lack of conformity must be given to the seller. Notice of defects conveyed by the buyer to an independent third party is not found to have been given by means appropriate in the circumstances. And Art. 39 is subject to the parties' power under Art. 6 to derogate from or vary the effect of any provision of the Convention. When determining which requirement must be satisfied by the buyer is specifying the nature of any lack of conformity, a mixed objective-subjective standard should be applied, which has regard to the respective commercial situation of the buyer and the seller, to any cultural differences, but above all, to the nature of the goods. Also to determine the specificity requirement is to satisfy the purpose of notice of lack of conformity.

This study attempts to fix an appropriate quantity of space evaluation, focusing on important furniture room visual environment elements. The major results of the study can be summarized as follows; 1. The degree of satisfaction in the living room is affected by an evaluational factor among factors of space evaluation. 2. In the space estimation for the furniture, the wall furniture is important in the living room because the arragement and occupying proportion of the wall furniture varies widely. 3. In the living room of the APT siza for the common people an appropriate quantity of furniture is classified into 3 types of the occuppying proportion. As the floor occupancy proportion supporting furniture is 13~19%, wall furniture is 10~16% and total furniture which combined both the supporting furniture and the wall furniture is 23~34%. Second, the proportion occupying the wall is 6~9% for the supporing furniture, 9~20% for the wall furniture, and 21~31% for the total furniture. Finaly the proportion occupying the space is 6~9% for the supporting furniture, 9~20% for the wall furniture, and 21~31% for the total furniture. Finaly the proportion occupying the space is 6~9% for the supporting, 6~10% for the wall furniture, and 11~16% for the total furniture.

The role of cost modeller is to facilitate the design process by systematic application of cost factors so as to maintain a sensible and economic relationship between cost, quantity, utility and appearance which thus helps in achieving the client's requirements within an agreed budget. There are a number of research on cost estimates in the early design stage based on the improvement of accuracy or impact factors. It is common knowledge that cost estimates are undertaken progressively throughout the design stage and make use of the information that is available at each phase, through the related research up to now. In addition, Cost estimates in the early design stage shall analyze the information under the various kinds of precondition before reaching the more developed design because a design can be modified and changed in all process depending on clients' requirements. Parametric cost estimating models have been adopted to support decision making in a changeable environment, in the early design stage. These models are using a similar instance or a pattern of historical case to be constituted in project information, geographic design features, relevant data to quantity or cost, etc. OLAP technique analyzes a subject data by multi-dimensional points of view; it supports query, analysis, comparison of required information by diverse queries. OLAP's data structure matches well with multiview-analysis framework. Accordingly, this study implements multi-dimensional information system for case based quantity data related to design information that is utilizing OLAP's technology, and then analyzes impact factors of quantity by the design criteria or parameter of the same meaning. On the basis of given factors examined above, this study will generate the rules on quantity measure and produce resemblance class using clustering of data mining. These sorts of knowledge-base consist of a set of classified data as group patterns, of which will be appropriate stand on the parametric cost estimating method.

This research was conducted to investigate the effects of irrigation quantity in irrigation management system controlled by drainage level sensors for perlite bag culture on the growth and yields of tomatoes during different growth stages. Tomato plants were irrigated with four selected methods; supplying small quantity (~70 mL) during entire growth (S-S), large quantity (~145 mL) during entire growth (L-L), small quantity before harvesting the first cluster fruits and large quantity after harvesting (S-L), and large quantity until harvesting the first cluster fruits and small quantity after harvesting (L-S). The irrigation quantity supplied in each time was gradually adjusted along with the ratios as the tomato crop grew during different growth stages. The growth of the tomato plants was unstable and slow during the entire cropping period when the plant was irrigated by small or large quantities (S-S or L-L). In L-S treatment, the growth phase of the tomato was changed from vegetative to generative growth on the basis of the plant development index when each irrigation quantity was changed. The L-S treatment exhibited the largest root volume and yields with stable drainage ratios. Therefore, the optimum irrigation quantity was determined as 145 mL before harvesting the first cluster fruits and 70 mL after harvesting.

Recommender systems reduce information overload and enhance choice quality. This technology is used in many services and industry. Previous studies did not consider recommendation quantity and the repetitive recommendations of an item. This study is the first to examine recommender systems by considering recommendation quantity and repetitive recommendations. Only a limited number of items are displayed in offline stores because of their physical limitations. Determining the type and number of items that will be displayed is an important consideration. In this study, I suggest the use of a user-based recommender system that can recommend the most appropriate items for each store. This model is evaluated by MAE, Precision, Recall, and F1 measure, and shows higher performance than the baseline model. I also suggest a new performance evaluation measure that includes Quantity Precision, Quantity Recall, and Quantity F1 measure. This measure considers the penalty for short or excess recommendation quantity. Novelty is defined as the proportion of items in a recommendation list that consumers may not experience. I evaluate the new revenue creation effect of the suggested model using this novelty measure. Previous research focused on recommendations for customer online, but I expand the recommender system to cover stores offline.
