On the foundation work of Po-Ryong power plant #3 & #4. It was 30meters away from the running states of #1 & #2 plant site. In order to protect the #1 & #2 power plant facilities & factory structure. Allowable vibration was required below 0.07 gal. Therefore, it had to set up the anti-vibration trench to reduce the vibration reference and secondary. I applied the low gravity and low velocity explosives with M/S delay caps by cautious blasting pattern.

Whole airplane recovery parachute system(WARPS) is a auxiliary safety system to protect occupants in emergency situation where recovery to normal flight condition is impossible. In this paper, application and certification cases of WARPS for Part 23 small airplane is introduced and considerations in certification of the WARPS installed airplane are provided in terms of performance of parachute, function and operation, loads and strength and protection of occupants.

The bipinnate-compound leaf of Parkia clappertoniana has prominent, long petiole with a pulvinal base. The pulvinus has wood, periderm, lenticels and extensive cortical layer. Its vascular bundles are elongated with alternating rays. The vascular bundles of the petiole, rachis and veins are oval, with conspicuous bundle caps. Stomatal complex is predominantly paracytic with occasional occurrence of anomocytic stomata near the midrib. The oval stomata have conspicuous stomatal ledges. Trichomes are unicellular, acicular and restricted to the rachis, petiole and pinnule mid-ribs and margin. Ecological and taxonomic significance of features is discussed.

In this paper, local industry target by analyzing the actual state of engineering education-oriented, demand for engineering education to come up with ways to improve. To this end, training human resources training program in engineering education practice Caps-tone design, Cooperative system, contract-type as the main theme of human resources in the southwestern industrial target academic staff investigate the actual conditions were run cooperative education programs. Survey, southwestern regional industry operating experience, most industry-university cooperative education program that was unsatisfactory. In addition, promoting Cooperative system experience in the industry will promote the future looked reservation position, while the Caps-tone design is somewhat academic partners participating a majority opinion education program run by the model will be developing. Regional strategy based on future demand for industry-oriented engineering education program for running is to come up with ways improvements.

Using the abundant available information about the tomato genome, we developed DNA markers that are linked to disease resistant loci and performed marker-assisted selection (MAS) to construct multi-disease resistant lines and varieties. Resistance markers of Ty-1, T2, and I2, which are linked to disease resistance to Tomato yellow leaf curl virus (TYLCV), Tomato mosaic virus (ToMV), and Fusarium wilt, respectively, were developed in a co-dominant fashion. DNA sequences near the resistance loci of TYLCV, ToMV, and Fusarium wilt were used for primer design. Reported candidate markers for powdery mildew-resistance were screened and the 32.5Cla marker was selected. All four markers (Ty-1, T2, I2, and 32.5Cla) were converted to cleavage amplification polymorphisms (CAPS) markers. Then, the CAPS markers were applied to 96 tomato lines to determine the phenetic relationships among the lines. This information yielded clusters of breeding lines illustrating the distribution of resistant and susceptible characters among lines. These data were utilized further in a MAS program for several generations, and a total of ten varieties and ten inbred lines were constructed. Among four traits, three were introduced to develop varieties and breeding lines through the MAS program; several cultivars possessed up to seven disease resistant traits. These resistant trait-related markers that were developed for the tomato MAS program could be used to select early stage seedlings, saving time and cost, and to construct multi-disease resistant lines and varieties.
