With the effectuation of Kyoto Protocol, one of the important movement throughout the world is reducing the emission of greenhouse gas which is the main reason of making global warming. The actual factor of greenhouse gas is CO2, and in year of 2002 20% of total CO2 emission was produced only through transportation throughout the South Korea. In the contrary, the recycling of municipal wastes in South Korea was 44.0% in 2002, but it will be targeted upto 53.5% in 2011. All of these show environment-conscious logistics should be implemented together throughout the each stage of distribution with the development of product and service. This study applied survey research for the activities affecting to the emission of CO2 and packaging wastes produced from transportation and packaging stages in logistics area. For this, survey questionary was constructed with five specific areas - strategy, transportation & distribution, custody, packaging, and information. Based on the 148 returned survey questionaries, this study analyzed 52 categories and finally suggests necessary modal shift, collaboration & co-operation in logistics, LCA(life-cycle assessment), and other promoting policies for the environment-conscious logistics in effective way.

In this paper, a minimum time path planning strategy is proposed for multi points manufacturing problems in drilling/spot welding tasks. By optimizing the travelling schedule of the set points and the detailed transfer path between points, the minimum time manufacturing task is realized under fully utilizing the dynamic performance of robotic manipulator. According to the start-stop movement in drilling/spot welding task, the path planning problem can be converted into a traveling salesman problem (TSP) and a series of point to point minimum time transfer path planning problems. Cubic Hermite interpolation polynomial is used to parameterize the transfer path and then the path parameters are optimized to obtain minimum point to point transfer time. A new TSP with minimum time index is constructed by using point-point transfer time as the TSP parameter. The classical genetic algorithm (GA) is applied to obtain the optimal travelling schedule. Several minimum time drilling tasks of a 3-DOF robotic manipulator are used as examples to demonstrate the effectiveness of the proposed approach.

As increasing needs of marine transportation , world merchant fleet and ship's size were enlarged and it caused frequent disasters in human lives and natural environment. By the reason of the above, they started to establish the Vessel Traffic System (VTS) at the European coast in 1960' and most of advanced contries established and managed it to prevent the sea traffic accidents in these days. The concept of traffic control at sea can be divided into three types. First, the initial gathering of informations about ship's identity and movement etc.. Second, monitoring of the traffic flow and amendment of instructions. Third , organization and direction of ships by allocating routes and speeds. Where the goal of traffic control is safety of traffics and developing effectiveness of navigation channel, if traffic volume is less tan channel capacity then the above first or second level of control would be sufficient but if it is bigger than that , more positive policy of control should be adopted as same as third type of the above. In this paper where the strategy of VTS is focused on the control of traffic density to be spread equality, as possible , all over the navigation channels and also improvement of effectiveness , it suggests algorithm to assign the vessels to the channels with balanced traffic density , and other algorithms using D.P. to sequence the vessels assigned to one channel in optimum order which decreases the mean waiting time in sense of channel effectiveness with numerical examples.

본 논문에서는, H.263 부호화기에 있어, 비제한 움직임 벡터(Unrestricted Motion Vector, UMV)모드와 기본 예측 모드(Default Prediction Mode)의 동적 선택을 위한 방법을 제안한다. 여기서, 움직임 보상된 영상과의 오차와 움직임 벡터의 크기를 이용하였다. 제안된 전략에서, UMV 모드는 모션 벡터의 크기와 움직임 보상된 영상의 오차에 따라 동적으로 적용된다. 이러한 전략은 UMV나 DPM을 고정적으로 전체 영상에 적용한 결과에 비해 화질 면에서 개선할 점을 제공한다. UMV 모드가 고정적으로 적용된 경우에 비해 움직임 추정 시 탐색 점의 수를 크게 줄일 수 있다. 제안된 방법은 카메라의 이동을 갖는 보다 긴 영상 신호에 대해 보다 효과적으로 적용될 수 있다.

Purpose: The purposes of this study were to develop a drum club activities program for soldiers and to explore the effects of the program on the mental health of soldiers. Methods: This study used one group pretest-posttest design. A drum club activities program for soldiers was offered for 12 weeks with each session of 2 hours. A total of 33 participants were recruited but eighteen participants who did not participate in sessions of the program more than 3 times were dropped out of the study. Finally, data from 15 participants were analyzed using the SPSS 22.0 program. Mental health status (stress, anxiety and aggression) was measured by Vibraimage technology. Vibraimage technology is a useful and objective method to identify the human psychophysiological state by analyzing the movement of various frequencies and amplitudes of head motion and face image using camera. Results: There is statistically significant difference in anxiety (Z=-3.12, p<.001) after implementation of the program. However, there was no statistically significant difference in stress and aggression. Conclusion: The results indicate that the drum club activities program was effective in decreasing anxiety in soldiers. The drum club activities program can be considered as a possible nursing intervention strategy to reduce anxiety for soldiers.

The import content of exports (ICE) is defined as the amount of foreign input embodied in one unit of export, and it has been used as a measure of the degree of integration into the global production network. In this paper, we suggest an alternative measure based on the decomposition of gross output and imports into the contributions of final demand terms. This measure considers the manner in which a country manages its domestic production base (gross output) and utilizes the foreign sector (imports) simultaneously and can thus be regarded as a more comprehensive measure than ICE. Korea's input-output tables in 1970-2018 are used in this paper. These tables were rearranged according to the same 26-industry classification so that these measures can be computed with time-series continuity and so that the results can be interpreted clearly. The results obtained in this paper are based on extended time-series data and are expected to be reliable and robust. The suggested indicators were applied to these tables, and, based on the results we conclude that the overall importance of the global economy in Korea's economic strategy has risen and that the degree of Korea's integration into the global production network increased over the entire period. This paper also shows that ICE incorrectly measures the movement of the degree of integration into the global production network in some periods.
