This study is to search a meaning of treagedy to show by the 6th generation through charecter's tragedy in the 6'th Generation Chinese film. For this, it examined an inner characteristic behind of the tragedy's moment and externalized ending in directors' films of the 6'th Generation's representation. The 6'th Generation of Chinese film reorganized newly Chinese film's cultural topography in the 1990s. The 6'th Generation films, which rebelled against the primary melody and the 5'th Generation on the system, is expressed commonly a tragedy moment with the time and space by character's tragedy. Characters of the 6'th Generation in the tragedy moment attempts various efforts to escape from the tragedy moment. However, no one can overcome the wall of reality, and their concealed emotion as keeping it out of the public eye lead that play. The moment that the 6th generation film meets a tragedy, the main character's accumulated tragedy situations begin to unfold all together. A tragedy embodied through : a collapsed tragedy due to the past's wound, a tragedy due to loss of jobs, a tragedy due to a family's departure, a tragedy from a time of chaos, a tragedy of a woman who became a head of a household and other tragedies.

The purpose of this study was to provide basic information on the propriety of the ready to wear garment sizes of Tween Generation(ages from 5th grade to 8th grade) who has different clothing preferences in color, styles, and design and also different body sizes and shapes from younger and older students. The objectives of the study were to ascertain (a) the body figure changes occurring during Tween Generation; (b) the coverage of manufactures'garment sizes. The body measurements of elementary school students(5th & 6th grades) and junior high school students(7th & 8th grades) provide the basic statistics for this study. The mean differences of each size within each figure type are compared by using t-teats. The differences in various manufacturers'apparel sizing and figure size are investigated. Also the body measurements and the apparel sizes of the manufacturers are compared in order to evaluate the suitability of the garment size. Results indicate that the body type factors are different in each age group. And manufactures'sizes come out to be much smaller than the actual body measurements. Young casual wear can cover junior high school students satisfactorily but for elementary school students, because of low drop-value, the overall satisfaction with filling is low.

Dentin bonding system have recently been developed in an effort to simplify and shorten bonding procedure. The intent of this study was to evaluate microleakage of newer generation of dentin bonding system comparing with other generations. Forty extracted human premolar teeth were randomly assigned to four groups for bonding : the 4th generation bonding system (Scotchbond Multi-Purpose). the 5th generation bonding system (Clearfil SE Bond), 6th generation bonding system (AQ bond) and 7th generation bonding $system(i-bond)^{TM}$ Class V cavities were prepared in buccal and lingual surface. The cavities were restored with composite resin (Z100) after the application of dentin bonding systems according to the instructions of the manufacturer Samples were thermocycled and immersed in methylene blue dye(2%). Each sample was sectioned with Isomet and evaluated for microleakage using stereomicroscopy. The mean value of the microleakage in 7th generation bonding system was greater than those of 4, 5, 6th generation dentin bonding system. Statistically, the mean values of microleakage between 4th and 7th generation bonding system were significantly different from each other (p<0.05).

It is important to reduce chair time and procedure in restorative treatment for children. Composite resin is not only used in esthetic restoration of anterior teeth but also posterior teeth by its improved physical property. The 7th generation dentin bonding system was recently developed in order to simplify three steps which is needed to bond composite resin to tooth surface-etchant, primer, adhesive. We compared shear bond strengths of 4, 5, 6, 7th generations dentin bonding systems. The primary dentin was pretreated with 4, 5, 6, 7th generation dentin bonding systems. Then composite resin was cured to the specimen using molds 2.5mm in diameter and 2mm in height. Thermocycling was performed and shear bond strength was finally measured. The results were as follow; 1. The mean values of shear bond strengths in 5th generation dentin bonding system(group 2) were greater than those of 4, 6, 7th generation dentin bonding system(group 1, 3, 4). The differences were statistically significant. 2. The mean values of shear bond strengths in 4th generation dentin bonding system(group 2) were greater than those of 6, 7th generation dentin bonding system(group 1, 3, 4). But, the differences were not statistically significant. 3. Between the mean values of shear bond strengths in 6, 7th generation dentin bonding system(group 3, 4) were similar.

This paper tries to elicit an optimal generation mix of Korea. Two approaches, using the screening curve method and taking advantage of a generation expansion planning tool, WASP-IV, are applied in getting the mix. The data used in this study is based on the 5th basic plan for long-term electricity supply and demand. The Load Duration Curve, that is needed for applying Screening Curve Method(SCM), is made based on the load profile in 2010. In our using SCM, the nuclear plant's operation characteristic, carbon emission cost and spinning reserve are considered. In using WASP-IV to get the adequate generation mix, the base and target demand forecasts in the 5th basic plan are used and the carbon emission cost is also considered. In this paper, It introduces the domestic adequacy generation mix in 2024 though SCM and WASP-IV.

These studies were conducted to investigate the development of chemical resistance in two-spotted spider mite (Tetranychus urticae Koch) through alternate selection for a given period of time with four acaricides including ethion of organophophours compound, dicofol of organo-chlorine compound, cyhexatin of organo-tin compound, and biphenthrin of synthetic pyrethroid compound; and to examine multiple-resistance among the acaricides to the selected populations. The development levels of chemical resistance in the two-spotted spider mite were greatly varied under alternate selection with the different chemical-group combination of four acaricides. Resistant levels of the ethion/dicofol-selected population at 13th-13th generation showed 49.4-fold resistance to ethion and 18.1-fold to dicofol; the ethion/cyhexatin-selected population at 9th-9th generation exhibited 28.1-fold to ethion and 5-fold to cyhexatin; the ethion/biphenthrin-selectd population at 10th-10th generation revealed 39.8-fold to ethion and 19.2-fold to biphenthrin. However, the dicofol/cyhexatin-selected population at 9th-9th generation showed 11.3-fold to dicofol and 4.9-fold to cyhexatin, and the dicofol/biphenthrin-selected population at 12th-12th generation exhibited 11.2-fold to dicofol and 9.4- fold to biphenthrin, while the cyhexatin/biphenthrin-selected population at 9th-9th generation revealed 3.7-fold to cyhexatin and 7.7-fold to biphenthrin. In case of alternate selection, the ehtion/dicofol-selected population revealed moderate multiple-resistance level to biphenthrin. The ethion/cyhexatin-selected and the ethion/biphenthrin-selected populations showed low mutiple-resistance level to biphenthrin and dicofol, respectively. However, the dicofol/cyhexatin-selected, the dicofol/biphenthrin-selected and the cyhexatin/biphenthrin-selected populations exhibited high multiple-resistance level to ethion.
