인터넷 환경에서 이러닝 시스템과 같은 고신뢰성의 정보를 원한다. 인터넷 시스템에서 프로그램과 데이터의 결함이 발생할 수 있기 때문에 신뢰성 분석이 매우 어렵다. 이 논문에서는 인터넷 환경에서 프로그램 신뢰성을 예측하기 위해서 유색 패트리넷 모델을 이용하는 신뢰도 예측 모델을 제안한다. 제안한 모델에 적용하는 신뢰도 분석 절차는 다음과 같다. 먼저, 인터넷 프로그램 모델을 만든다. 이를 유색 패트리넷으로 변환한 후 인터넷 시스템 모델의 신뢰도를 예측한다. 이 방법은 신뢰성 있는 인터넷 프로그램을 개발하는 데 도움을 줄 수 있고, 신뢰도 예측 방법이 매우 간단하기 때문에 적용하기 편리하다.

South Korea and developing countries like Uganda have sought to re-energize their agriculture sector growth using 6th Industrialization of Agriculture strategies. These strategies seek to upgrade farming households from just being producers or primary industry players to participants in the secondary and tertiary industry. This convergence is known as 1x2x3 = 6th Industrialization. This involves farmers strengthening production and investing in higher value chain activities such as agrotourism, agro-processing, farm restaurants, and the export market. These developments are driven by investment in institutional arrangements and technology that is often beyond the capacity of individual farming households as well as some farmer organizations and cooperatives. Qualitative approaches were used to draw lessons from two typical rice farmer organizations and two rice value addition groups and other sector players to investigate group formation dyanamics and the capacity of farmer organizations to attain goals for grouping. The results show being a member of a farmer organization increases access to inputs such as machinery, however, the key determinant to joining is trust/mistrust of leadership. In regard to attainment of 6th Industrialization, farmer organizations still have to hassle with uncertainty of marketing a new 6th industry product. Nevertheless farmer organizations seem closer to attaining the 6th industry goal due to exposure to primary processing and export business. Some implications have been drawn for Korea as well as localization to Uganda’s situation.

The purpose of this study is to show objective data about the amount of the activity of the referee in an actual game, and to use these for the referee training in the future. As a result of consideration, the main referee became clear that an equal ability of moved distance, the movement speed, and the turn frequency, etc. with the field player was demanded. The main referee showed total moved distance twice the sub?referee, and this moved distance was almost equal to the field player. Moreover, it has been understood that a considerably high ability is demanded from the main referee about brilliant because the frequency about four times the sub?referee of the turn is done. Therefore, the main referee is doing advanced work of giving a decision while equal stamina's with the field player being demanded and repeating the turn and the movement according to a diagonal method. On the other hand, the moved distance of the sub?referee was main referee and field player's halves. Moreover, it is thought that the sub?referee is giving the judgment (offside and ball out) in the stopped state at the moment from low?speed movement frequency high. The future tasks are to analyze the accuracy of the work of the sub?referee by comparing sub?referee's position with the position of an offside line, and to consider the sub ?referee qualitatively.

The purpose of this study was to make clear what affects the running speed of a player in a game. This research made the game of soccer of two games a research object. Two games of these were Japan versus UAE and Sanfrecce Hiroshima versus Yokohama Marinos. The method of calculating the amount of the activity used three dimensions DLT method. First of all, it takes a picture to install the entire pitch from the main stand rooftop in the competition site on each camera in two video cameras and this image is capture in PC every 1/3 seconds. And, the three?dimensional image analysis software was used, digitized, player's movement and the ball were converted into objective positional coordinates, and the amount of the activity was calculated on coordinate data. The following results were obtained by analyzing these data. In the J league game, the average speed of the ball was 6.04±6.26m/sec in the first half, and 6.23±5.52m/sec in the second half. In the game Japan versus UAE, the average speed of the ball was 6.11±6.29 in the first half, and 5.12±6.56 in the second half. The change of the average running speed of the field players of a team was highly affected by the change of the ball speed from both 2games.
