Due to development of digital technology, a concept of stage design management is being changed. In addition, stage management technique is changing a viewpoint of the audience watching a stage through the convergence of analogue and digital technology. Three-dimensional media such as LED and hologram and works combining with previous stage performances are rising, and the audience's requirements about spectacles on the stage are increasingly higher. Interaction between a stage, audiences and actors is a communication tool by a work story and its direction. In other words, stage design should newly focus on not only concluded work story but also comprehensive delivery of direction and the expression and extreme delivery. Therefore, this study aims to examine how to combine analogue and digital direction elements in the stage design. To this end, this study looks into everything the audience feels through performances and analogue and digital elements directed for performances and then analyzes and arranges them to present a possibility of various types of work performances. Stage structure, set, and lighting that are analogue direction elements are the basis of stage performance. Analogue direction elements mean a media vehicle that can differentiate except for basic direction of each work. This study aims to analyze new performance culture when analog and digital direction elements are combined through stage performance and a possibility of new stage performance. In addition, through this it desired to seek for a development possibility of Korean leisure culture and art culture. As the work cases, this study shows 10 works through actual stage performances held in Korea and introduces elements directed in those works.

Recently, to develop GaN-based light-emitting diodes (LEDs) with better performances, various approaches have been suggested by many research groups. In particular, using the patterned sapphire substrate technique has shown the improvement in both internal quantum efficiency and light extraction properties of GaN-based LEDs. In this paper, we discuss the influences of the direction of the hexagonal-structure arrays of lens-shaped patterns (HSAPs) formed on sapphire substrates on the crystal, optical, and electrical properties of InGaN/GaN multi-quantum-well (MQW) LEDs. The basic direction of the HSAPs is normal (HSAPN) with respect to the primary flat zone of a c-plane sapphire substrate. Another HSAP tilted by 30o (HSAP30) from the HSAPN structure was used to investigate the effects of the pattern direction. The full width at half maximums (FWHMs) of the double-crystal x-ray diffraction (DCXRD) spectrum for the (0002) and (1-102) planes of the HSAPN are 320.4 and 381.6 arcsecs., respectively, which are relatively narrower compared to those of the HSP30. The photoluminescence intensity for the HSAPN structure was ~1.2 times stronger than that for the HSAP30. From the electroluminescence (EL) measurements, the intensity for both structures are almost similar. In addition, the effects of the area of the individual lens pattern consisting of the hexagonal-structure arrays are discussed using the concept of the planar area fraction (PAF) defined as the following equation; PAF = [1-(patterns area/total unit areas)] For the relatively small PAF region up to 0.494, the influences of the HSAP direction on the LED characteristics were significant. However, the direction effects of the HSAP became small with increasing the PAF.

Along with the increasing need of sea development, the hydraulic stability of seabed structure on a soft seafloor ground is becoming an issue in the course of seaside development recently. However, the movement and hydraulic resistance or hydraulic stability of seafloor ground are mutually coupled with various phenomena, and there has been no clear proof for the issue, which makes it difficult to forecast. Furthermore, most researches are focused on hydraulic variables and the conditions of marine external force, while there have been few researches into the assessment in consideration of the type of a seafloor ground and the geotechnical characteristics. In addition, according to the periodic change of the flow direction, possible changes in hydraulic resistance performance of the seafloor deserves all the recognition. But there is no way to measure the hydraulic unstability of the sea ground due to tidal flow quantitatively. In this study, conventional hydraulic resistance measurement apparatus was improved to consider direction change of the current flow. Various artificial clayey soil specimens were made from Kaolinite and Jumunjin standard sand and hydraulic resistance tests were performed by changing the flow direction to validate the effect of the direction change on the scour of the seafloor.

Behavior of the side force generated at high angles of attack by two ogive-cylinder bodies of revolution with nose fineness ratio of 2.3 (B1) and 3.5 (B2) and the effect of a strip placed close the nose tip of each body (B1S and B2S) are analyzed through the wind tunnel test at ReD=200,000 and a=42~60 deg. The side force generated by B1 is increased by placing a strip. The side force generated by B2 is in the starboard direction and its magnitude is higher than that of the B1S. The effect of the strips with various dimensions placed on B2 is investigated. It is found that the 4-layer strip placed on the starboard reversed the direction of the side force into port direction. It is confirmed by numerical simulations that the strip promotes the flow separation and increases the average pressure on the side where it is placed and consequently produces the side force in the corresponding direction.

This paper aims to explain the direction of a long-range policy for the development of fisheries industry and fishing villages in Korea after the Conclusion of the Uruguay Round Negotiations. When the Uruguay Round Negotiations were concluded last year, the government soon set up the Committee of Farming and Fishing Village Development under the direct control of the President and launched on the development of agriculture and fisheries policy to provide for the post-Uruguay Round. The Committee drew up an all-round policy report, "The Problem and Direction of Agriculture Policy Reform" as a result of the six-month activity of this committee from February through July, 1994 in which the author participated, and presented it to the President. The author rearranged the problems of a long-range policy related to fisheries industry and fishing villages apart from this report, and drew up another report under the title, "Fisheries Policy in Korea after the Conclusion of the Uruguay Round Negotiations : Its Problem and Direction," which was reported at the year 1994 autumn symposium of the Korean Pedagogic Society of Fisheries and Marine Sciences.

Until now, Many papers were written by graduate school students and consultents about railway station as main consideration. But there is no paper about specific private-invested station development. So in this paper, Just consider limiting Dong-Incheon private-invested station on a noncompetitive point of view that also constructed as a part of railway station development. This paper will be referenced of private-invested station management and direction of development in Korail railway station development. Private-invested station development is actively drived to now after Seoul private-invested station in 1989 as Korail's first induced private capital. Dong-Incheon private-invested station also built in 1989 and operated to now, but it can't keep up with current market and can't meet changeable commercial business. So in this paper, comparing Dong-Incheon private-invested station with one of the successful private-invested stations which is youngdengpo private-invested station and seeking the improvement direction of Dong-Incheon private-invested station as considering Dong-Incheon private-invested station's floating, traffic system, walking line, the range of station, the development type, facilities, and other nation's developing cases.

This study had two purposes. First, to examine the stages and developmental order of object permanence based on Piaget's theory. Second, to assess the effects of delay, attentiveness, and direction of gaze. Two experiments were conducted to examine the object permanence development in infants. The subjects for the 2 experiments were randomly drawn from a well-baby clinic. The subjects for Experiment 1 were 72 infants, 12 each in 6 age levels : 6, 9, 12, 15, 18, and 21 months old. Experiment 1 was designed to examine the stages and developmental order of object concept development, ana infants received 5 tasks as follows : (1) finding an object partially hidden under one box (2) finding an object completely hidden under one box (3) finding an object after successive visible displacements (4) finding an object after one invisible displacement (5) finding an object after successive invisible displacements. The subjects for Experiment 2 were 24 9-month-olds. Experiment 2 was designed to assess the effects of delay, attentiveness, and direction of gaze for Stage IV of object concept development. Subjects were equally assigned into one of two delay groups: 0-sec delay and 3-sec delay. Attentiveness was rated in terms of a three-point scale, and then divided into high and low attentive groups. Direction of gaze was judged into two directions. In two experiments, infants received three trials of task, and received a score of 0, 1, 2 for each trials. Data were analyzed by ANOVA, Tukey test, and t-test for task performance, and direction of gaze was analyzed by chi-square. The results obtained from two experiments were as follows : 1. In object permanence test, subjects obtained significantly higher scores with age, and 6, 9, 12, 18 months were classified into different developmental stages. 2. In object permanence development, subjects received significantly different scores with task and a developmental order of tasks was found. First of all, infants mastered finding an object partially hidden under one box, and then mastered finding an object completely hidden under one box. Contrary to Piagetian theory, in this study, the development of finding an object after successive visible displacements and finding an object after one invisible displacement were sometimes reversed. Finally, finding an object after successive invisible displacements was mastered, and the concept of object permanence was completed. 3. In Stage IV of object concept development, a 3-sec delay did not significantly affect the performance of tasks. The O-sec delay group didn't perform significantly better than the 3-sec delay group. 4. In Stage IV of object concept development, attentiveness of infants significantly affected the performance of task. So the highly attentive infants obtained better performance scores than the low attentive infants. 5. In Stage IV of object concept development, direction of gaze significantly affected the performance of task. That is, infants who gazed at the box which contained the object showed a higher rate of success than infants who gazed at the box which had already displaced the object.
