The physical condition of rapeseed delivered to fat industry plants plays a significant role in the formation of the qualitative features of the raw material for oil production and, consequently , of the oil itself. Rapeseed is stored in silos , frequently for months, before it is subjected to processing. During the long storage, the conditions of the seed cover is very important, as the seed cover provides natural protection of the seed against the effect of the environment. Seeds with damaged seed cover are more easily affected by mildew, and the rate of chemical processes. Deteriorating the quality of oil contained in the cotyledons is faster in such seeds. Cracked seed covers facilitates also the growth and development of microorgaism. So as rapeseed damage occurring inthe course of harvest and the post-harvest processing have a negative effect of the quality and quantity of oil the sees contain. The study presented here was aimed at examining the typical process of purcha ing and handling of rapeseed in fat industry plants, in the aspect of the occurrence of mechanical damage to the seeds. Special attention was paid to the condition of rapeseed immediately after combine harvesting : next , the successive stages of technological handling of the seed were examined. observing the operation parameters of the particular machinery and equipment in order to identify those operations which caused deterioration in the quality of the material (sees). Seed samples were taken successively from the following the hopper, prior to cleaning , after cleaning , prior to drying , after drying, from dry rape silo. The total level of damage increased through the handling. The content of unusable contaminants had the tendency to decrease in the successive operations. though the actual values still exceeded levels permitted by standards. The study allow to indicate the operation fo postharvest technological process, which cause the most seed damage as well as gave quantita ive description of the losses occurred.

As the amount of radioactive waste and related information to be managed are increasing, some organizations are trying or planning to computerize the management on radioactive waste. When we consider that information on safe management of radioactive waste should be used In association with national radioactive waste management project, standardization of data form and its protocol is required. Korea Institute of Nuclear Safety(KINS) will establish and operate nationwide integrated database in order to effectively manage a large amount of information on national radioactive waste. This database allows not only to trace and manage the trend of radioactive waste occurrence and in storage but also to produce reliable analysis results for the quantity accumulated. Consequently, we can provide necessary information for national radioactive waste management policy and related industry's planing. This study explains the database design which is the essential element for information management.
The performance of spatio-temporal moving pattern mining depends on how to analyze and process the huge set of spatio-temporal data due to the nature of it. The several method was presented in order to solve the problems in which existing spatio-temporal moving pattern mining methods[1-10] have, such as increasing execution time and required memory size during the pattern mining, but they did not solve properly yet. Thus, we proposed the STMP/MST method[11] as a preceding research in order to extract effectively sequential and/or periodical frequent occurrence moving patterns from the huge set of spatio-temporal moving data. The proposed method reduces patterns mining execution time, using the moving sequence tree based on hash tree. And also, to minimize the required memory space, it generalizes detailed historical data including spatio-temporal attributes into the real world scopes of space and time by using spatio-temporal concept hierarchy. In this paper, in order to verify the effectiveness of the STMP/MST method, we compared and analyzed performance with existing spatio-temporal moving pattern mining methods based on the quantity of mining data and minimum support factor.
Soil erosion, transportation, and sedimentation by water flow often occur in a stream. This excessive occurrence threatens the safety of hydraulic structures, and aggravates natural disasters like flood. To prevent soil disaster according to the soil erosion, it is necessary to predict accurate sediment outflow primarily. Besides, it is very important to choose appropriate models by basin characteristics, to estimate accurate quantity of related factors, and to acquire available hydrological data. Therefore, the purpose of this study is to estimate soil erosion amount and sediment amount according to rainfall-runoff by using rainfall, discharge, and sediment in the Seolmacheon experimental catchment. And, it proposed sediment delivery ratio of the Seolmacheon catchment by result of studying sediment delivery ratio. Hereafter, this study will estimate sediment delivery ratio by basin characteristics, and formulate the method of estimating soil erosion and sediment outflow in various conditions by applying the results in other catchments.

Polymer insulating materials such as cross linked polyethylene (XLPE) are employed in electric cables used for extra high voltage. These materials can degrade due to chemical, mechanical and electric stress, possibly caused by voids, the presence of extrinsic materials and protrusions. Therefore, this study measured discharge patterns, discharge phase angle, quantity and occurrence frequency as well as changes in XLPE under different temperatures and applied voltages. To quantitatively analyze the irregular partial discharge patterns measured, the discharge patterns were examined using a statistical program. A three layer sample was fabricated, wherein the upper and lower layers were composed of non-void XLPE, while the middle layer was composed of an air void and copper particles. After heating to room temperature and $50^{\circ}C$ and $80^{\circ}C$ in silicone oil, partial discharge characteristics were studied by increasing the voltage from the inception voltage to the breakdown voltage. Partial discharge statistical analysis showed that when the K-means clustering was carried out at 9 kV to determine the void discharge characteristics, the amount discharged at low temperatures was small but when the temperature was increased to $80^{\circ}C$, the discharge amount increased to be 5.7 times more than that at room temperature because electric charge injection became easier. An analysis of the kurtosis and the skewness confirmed that positive and negative polarity had counterclockwise and clockwise clustering distribution, respectively. When 5 kV was applied to copper particles, the K-means was conducted as the temperature changed from $50^{\circ}C$ to $80^{\circ}C$. The amount of charge at a positive polarity increased 20.3% and the amount of charge at a negative polarity increased 54.9%. The clustering distribution of a positive polarity and negative polarity showed a straight line in the kurtosis and skewness analyses.
Background: Substantial empirical research has shown conflicting results regarding the influence of organizational external factors on construction risk management, suggesting the necessity to introduce a moderator into the study. The present research confirmed whether rules and regulations matter on the relationships between organizational external factors and construction risk management. Methods: Based on discouragement and organizational control theory, this research examined the effects of organizational external factors and rules and regulations on construction risk management among 238 employees operating in construction companies in Abuja and Lagos, Nigeria. A personally administered questionnaire was used to acquire the data. The data were analyzed using partial least squares structural equation modeling. Results: A significant positive relationship between organizational external factors and construction risk management was asserted. This study also found a significant positive relationship between rules and regulations and construction risk management. As anticipated, rules and regulations were found to moderate the relationship between organizational external factors and construction risk management, with a significant positive result. Similarly, a significant interaction effect was also found between rules and regulations and organizational external factors. Implications of the research from a Nigerian point of view have also been discussed. Conclusion: Political, economy, and technology factors helped the construction companies to reduce the chance of risk occurrence during the construction activities. Rules and regulations also helped to lessen the rate of accidents involving construction workers as well as the duration of the projects. Similarly, the influence of the organizational external factors with rules and regulations on construction risk management has proven that most of the construction companies that implement the aforementioned factors have the chance to deliver their projects within the stipulated time, cost, and qualities, which can be used as a yardstick to measure a good project.

The paleovegetation environments relevant to the geomorphic properties were constructed by pollen analysis in the coastal dune (S1) and marginal trench (S4) of Ssangho at the Osan-ri site. The organic sand layer in the coastal dune (S1) accumulated on the remains of the Neolithic Age correlates to approximately 4,000 yr BP and the pollen zone can be divided with a boundary of approximately 2,000 yr BP. Pinus thunbergii definitely dominated and a small quantity of Quercus. Pollenzone I can be characterized by the dominance of AP and Compositae. The pollenzone II as the dominant period of NAP like Gramineae, Artemisia and Fagopyrum shows the properties of agricultural period. During the times of accumulation of upper organic layer in alluvial plain (S4), broad-leaved trees such as Alnus were dominant and Compositae, Gramineae, Artemisia, Typha, Umbelliferae and Persicaria show the high occurrence rates. The pollen composition of S4 indicates the agricultural activities with the dominance of NAP and correlates to the pollenzone II of the coastal dune (S1).

In super-tall building construction projects, schedule risk factors which vertically change and are not found in the low and middle-rise building construction influence duration of a project by vertical attribute; and it makes hard to estimate activity or overall duration of a construction project. However, the existing duration estimating methods, that are based on quantity and productivity assuming activities of the same work item have the same risk and duration regardless of operation space, are not able to consider the schedule risk factors which change by the altitude of operation space. Therefore, in order to advance accuracy of duration estimation of super-tall building projects, the degree of changes of these risk factors according to altitude should be analyzed and incorporated into a duration estimating method. This research proposes a simulation model using Monte Carlo method for estimating activity duration incorporating schedule risk factors by weather conditions in a super-tall building. The research process is as follows. Firstly, the schedule risk factors in super-tall building are identified through literature and expert reviews, and occurrence of non-working days at high altitude by weather condition is identified as one of the critical schedule risk factors. Secondly, a calculating method of the vertical distributions of the weather factors such as temperature and wind speed is analyzed through literature reviews. Then, a probability distribution of the weather factors is developed using the weather database of the past decade. Thirdly, a simulation model and algorithms for estimating non-working days and duration of each activity is developed using Monte-Carlo method. Finally, sensitivity analysis and a case study are carried out for the validation of the proposed model.

In contracts for the international sale of goods, a seller must deliver appropriate goods and hand over relevant documents according to a contract, which will transfer the ownership of the goods to a buyer. In this case, if there are defects in the contracted goods, the warranty liability will occur. However, in the United Nations Convention on Contracts for the International Sale of Goods (CISG), a term-the conformity of the goods to the contract-is used universally instead of the warranty. According to the CISG, a seller must deliver goods in conformance with the relevant contract in terms of quantity, quality, and specifications, and they must be contained in vessels or in packages according to the specifications in the contract. In addition, a certain set of requirements for conformity will be applied implicitly except when there is a separate agreement between parties. Further, the base period of conformity concerning the defects of goods is the point when the risk is transferred to the buyer. A seller shall be obliged to deliver goods that do not belong to a third party or subject to a claim then, and such obligations shall affect the right or claim of a third party to some extent based on intellectual property rights clauses. If the goods delivered by the seller lack conformity, or incur right infringement or claim of a third party, then it shall be regarded as a default item per the obligation of the seller. Thus, the buyer can exercise diverse means of relief as specified in Chapter 2, Section 3 (Article 45-Article 52) of the CISG. However, such means of relief have been utilized in various ways for individual cases as shown in judicial precedents made until now. Contracting parties shall thus keep in mind that it is best for them to make every contract airtight and they should implement each contract thoroughly and faithfully to cope with any possible occurrence of a commercial dispute.
