최근 흥행에 성공한 타이타닉, 스타워즈 에피소드II, 매트릭스, 해리포터, 반지의 제왕 등 대부분 헐리우드 영화는 제작 공정의 50% 이상을 CG기술을 활용하여 제작하였다. 그리고, CG 기술을 활용함으로써 제작 경비도 획기적으로 절감할 수 있었다.(중략)

Portable navigation markets grew up to 95% last year. This study aims to develop a business model for pedestrian-oriented portable navigator for street shoppers. Related previous studies developed successfully the alogrithm for a portable navigator, and the current study seeks for diverse ways to turn this system into a new type of on & off line-based LBS business. The business model proposed in this study adopted two different approaches of benefit yields based on the structural analysis of so-called Wanavi navigation system. One is segmented approach seeking for benefits from each individual system component such as communication network, contents, and platform. The other approach is to run the business by integrating relevant system componts in every possible way to attract customers to this portable navigator. The purpose of this proposal is not limited to activate emerging walking navigator markets, but to aim at creating idealistic free market system where all the shoppers are furnished complete market information to the fullest extent when they go on shopping.

This paper examines agri-food export competitiveness among 4 countries(Korea, USA, Japan, China) based on Porter's Diamond model approach. Korea agri-food competitiveness index is much less than those of other countries. Korea is the lowest ranked among the 4 countries in terms of three determinants(except 1 factor, related and supporting industries) of Porter's Diamond Model: Factor condition, demand condition, firm strategy, structure and rivalry. Korea is assumed to have weak point in the factor condition, demand condition because of low capital and land as well as insufficient investment on the agri-food sector. on the other hand, it seems to have strong factor in consumer condition(demand condition). This paper suggest the following strategies to reinforced the agri-food export sector in Korea. 1) an incentive system for seed development and capital investment, 2) a cluster strategy between agriculture and related industry.

It is an important element increasing ship production to manage an accurate position of transporters(TP) and ship blocks in a shipyard. However, most works are presently being performed by judgment of a system manager and skilled workers. This paper introduced about the system for tracking an accurate position of the transporters and the blocks which are main mobile objects in the shipyard, and proposed a method to decide whether or not a loading/unloading state of the blocks, which is one of the most important functions of the tracking system. Three sensors were used in order to implement the method. One is a RFID reader to identify a target block, another is a RFID reader to estimate a position of the TP as it recognizes a underground tag. The other is a ultrasonic sensor to detect an object. Two experiments were carried out in the shipyard. After correcting errors found on the first experiment. we confirmed that the result could be applied to the shipbuilding yard from the final experiment.

In this research, we try to find the conditions under which profit maximizing labor demand increases with pollution abatement activities under the environmental protection policy. Especially, we focus only on the technological advances in traditional production process caused by the spillover effect of pollution abatement technology. Even if Porter's hypothesis(1995) are given, we argue that it is not enough for the society to enjoy the benefits from the innovation with the strengthen of firms' competitiveness. To spread the benefits over economic agents in a society, especially including labor-owner, the current level of pollution abatement technology is important. When the level of pollution abatement technology is appropriate, both the environment protection and the job creation can be achieved through the government policy for environment protection.

Vehicle engineering analysis in the event of an accident caused by a car built on mechanical design has not been investigated in-depth but relies on the subjective experience knowledge of the investigator. This study analyzed the correlation between the speed, progress, steering, and braking before impact, which is consistent with the final stop position, by drawing a site situation chart using the CAD (CAD) program and repeating 250 crashes using the PC-Crash program. The following situations were investigated: lower impact velocity; greater impact speed of the vehicle, which is not affected significantly by the departure angle; higher vehicle speed, such as the effective impact velocity, after the impact; higher vehicle speed; and lower vehicle speed. (Ed note: I am unsure what you are saying here. It appears contradictory and not a complete sentence. Please check the changes.)The simulation results of this study identified the process of returning to the magnetic progression lane after recognizing the opposite porter while Mighty was carried out on the uphill left-curve section in a position that crossed the center line, and the collision of the porter's front left side, pushing the porter in the right diagonal direction and making the front stop towards approximately 11 o'clock.

The widespread adoption of aluminum slab formwork in modern construction, evident in both domestic and international projects, offers numerous advantages. However, a critical challenge persists regarding the dismantling process for these slabs. The current industry standard involves dropping the slabs to the ground floor upon removal. This practice raises several concerns, notably the generation of significant noise pollution that disrupts nearby communities. More importantly, the risk of worker injuries due to falls from height during the dismantling process is a serious safety hazard. Additionally, the impact from dropping the slabs can damage the aluminum itself, leading to increased replacement costs. These drawbacks necessitate the exploration of alternative dismantling techniques that prioritize worker safety, material sustainability, and overall process efficiency. Accordingly, in this study, when the entire first-generation slab formwork of an apartment house is simultaneously lowered to a reachable position for workers, it is then disassembled and lifted for transport to the next floor. This approach has the potential to demonstrate improvements in safety, quality, economy, and process efficiency.

지금 부터 10년 전 1995년, 한신대지진이 일어났던 일본은 너무나도 갑작스런 큰 지진의 큰 비극을 잊지 못하고 있다. 그 때 전국 각지에서 모여든 자원봉사자들의 많은 활동과 의료복지 분야의 원조, 그리고 일반 회사원들도 장기휴가로 자원봉사 활동에 참가했던 풍경이 아직도 잊혀 지지가 않는다. 지진의 재해에서 피할 수 없는 일보 열도, 지금도 여기저기에서는 작은 지진이 일어나고 있다.
