In recent years there have been growing interests in the potential environmental effects of global climate change. Of specific interests is the role that climate change may play in altering natural volatile organic compound.(NVOC) emissions from trees and the subsequent impact of this perturbation on air quality and ozone formation. A novel vegetation enclosure chamber method was designed and constructed of Tedlar in order to estimate more accurate and precise NVOC emission rates of either small whole plants or the branches of large trees. The enclosure chamber was initially tested in the laboratory and also successfully evaluated in the field. Overall precision for this enclosure was estimated as RSD<10%(n=9). The overall errors associated with the enclosure method in a laboratory system might be relatively small (say<$\pm$15%); however, they might be rather large(say$\pm$40%) in a field-based system. Two consecutive samples were collected on each sampling day from the two pine species during the test period. Slash pine studies showed that the absolute percentage difference between the first and second samples varied from 0.33 to 29%. The percent differences between consecutive emission for loblolly pines varied from 0.74 to 24.2%.

The effect of thinned trees which are produced from forest thinning on forest fire was studied in this work. To investigate the effect of thinning slash, Yang-yang, In-je, and Ga-pyeong-gun were selected as thinning-areas and non-thinning areas. The research was carried out with the variations of tree's types, area's characteristics, thinning strength, thinning types, and pile types of thinned tree. The survey areas of 14 areas were selected at Yangyang-gun(5 areas), Gapyeong-gun(4 areas), and Inje-gun(5 areas), and on-the-spot investigations were carried out at the thinning areas of 9 and the non-thinning areas of 5, respectively. Non-thinning areas of 5, which are adjacent to thinning areas, were selected for the comparison with thinning areas and for the analysis of risk of forest fire. It is considered that forest fire have no chance to diffuse to a tree trunk because the height of thinned trees was lower than 1 m. However, it is considered that forest fire may affect directly to a tree trunk if it spread to piled thinned tree because there was no space between thinned trees and trees. Furthermore, it was found that re-ignition had a chance to occur due to lots of piled thinning trees.

Loblolly(Pinus taeda L.) and slash(Pinus elliottii Engelm.) pines are the most important timber producing species in the Southern United States. Site index equations to estimate site index curves(base age 25 years) for loblolly pine and slash pine plantations have been developed based on long-term repeated measurement data sets. To check magnitude of errors in estimating site index, each cumulative measurement cycle data sets and all combined data sets were used to recalculate site index values. The Chapman-Richards' growth function was selected for stand height prediction. Anamorphic base age invariant site index curves were presented based on this height prediction equation. Statistics used in the evaluation were mean of the differences and mean of the absolute differences. For plantation ages less than 5 years, site index values showed very sensitive fur both species based on the evaluation test.

We use Borcherds products to give a new construction of the weight 3 paramodular nonlift eigenform f_N for levels N = 61, 73, 79. We classify the congruences of f_N to Gritsenko lifts. We provide techniques that compute eigenvalues to support future modularity applications. Our method does not compute Hecke eigenvalues from Fourier coefficients but instead uses elliptic modular forms, specifically the restrictions of Gritsenko lifts and their images under the slash operator to modular curves.

Strobilus initiation in grafted, 18-year-old slash pine (Pinus elliottii var. elliottii) in a seed orchard was examined in relation to morphological and anatomical characteristics of shoots. Needle weight (total fresh weight of needles per shoot produced during the current growing season) was the most closely related single variable to the number of female flowers produced the following year ($R^2=0.41$). The number of female and male strobili (per shoot) produced the following year was positively and negatively correlated, respectively, with the total weight of current-year needles per shoot. A transition from male to female flowering was associated with increasing vigor (number of needles) of the shoot. Vegetative buds in the upper parts of the crown of poor-flowering trees showed more advanced growth of vascular tissues compared with female-or male-producing buds, indicating a strong favor for vegetative growth.

The aim of this study is to clarify the style of fashion design which represented three types of erotic mood. And it will have its significance in finding out some standards which call be applied to practical designing. The positive analysis on this study is composed of two parts-the analysis of fashion journals and of questionaire. Analysis of fashion design is to seize and to compare frequence of 17 style of fashion design in the delivery of erotic mood in $\ulcorner$Mot$\lrcorner$ and $\ulcorner$Vogue$\lrcorner$. The questionaire is to investigate preference and inclination of perception in erotic mood of 17 style of fashion design by sex and age. The results were as follows: 1) In $\ulcorner$Vogue$\lrcorner$ than in $\ulcorner$Mot$\lrcorner$ erotic style ate actively made use of. 2) To suggest style of fashion design expressed 3 moods of erotic can be applied to practical designing is as follows. Expression of 'romantic & mysterious' mood is desirab]e exposed body line in motion style in male, twenties and thirties. Expression of 'seductive h stimulating' mood is desirable bosom exposure, leg exposure, adhere of bosom, adhere of waist, seen-through leg, slit, exposed body line in motion style in male and twenties and seen-through bosom, adhere of hip, slash style in male. This mood is desirable exposed body line motion style in thirties and forties. Expression of 'sensuous & attractive' mood is desirable bosom exposure, leg exposure, adhere of bosom, adhere of waist, seen-through leg, slit, exposed body line in motion style in male and twenties and adhere of hip, seen-through bosom, slash style ill male. And this mood is desirable adhere of waist, arm exposure style in female and adhere of waist, exposed body line in motif style in thirties and forties.

The purpose of this study was to examine what consumers virtyally thought about deconstructional method used in fashion and its cloths. For attaining the purpose, earlier studies were reviewed to see what kind of deconstructional methods were used in fashion and its cloth, and questionnaire survey was carried out based on the result. 10 kinds of deconstructional method were surveyed : indeterminate form, lingerie look, layering, unsymmetrical form, seethrough cloth, slash or making a hole, fray, padded cloth, patchworked cloth, and wrinkled cloth. There appeared 6 kinds of image for deconstructional fashion, esthetics, womanliness, youth, elegance, uniqueness, and fashionability. Consumers considered most deconstructional fashion to be unique but unique but lack elegance. However, they didn\`t feel indeterminate form, fray or padded cloth was unique, and one notable thing was that they had an impression wrinkled cloth was graceful. The design assessed to be generally esthetic was lingerie look, laying, seethrough cloth and wrinkled cloth. Those who were older set more esthetic value on layering, seethrough cloth, fray, padded cloth and wrinkled cloth. On the contrary, they didn\`t have a good impression from slash, making a hole or patchworked cloth. As a result of investigating the subjects\` willingness to wear deconstructional design, there was deconstructional design which they might possibly put on, and those who were older found more difficulties in wearing ir. Toward indeterminate and layering fashion, younger people whose age was ranged from 18 to 22 or from 18 to 22 or from 23 to 27 showed particularly better response. Married woman wanted to wear wrinkled cloth, and considered it possible to put on seethrough design more than unmarried women. Rather, younger people were more unwilling to wear seethrough design.

분명한 것은 한국형 온라인게임의 특징적 원리들이 탑재되고 있는 방식과 현상은 점차 강화되고 있음에도 불구하고 게임사 주도적으로 전개되고 있는 산업의 성장모형은 평가기능으로 작동해야 할 조정 메커니즘의 원활한 흐름을 저해하는 길항관계에 있는 것은 사실이다. 이러한 문제를 인식하고 연구자는 게임연구의 활성화지점과 게임개발 테크놀로지가 가진 길항관계를 보완할 수 있는 디자인에 주목하고자 하였다. 게임디자인은 게임의 미적, 실용적, 경제적 가치를 창출하는 직무이면서 유관 콘텐츠산업과의 연계와 매개 가능성을 함의하고 있다는 측면에서 게임연구의 활성화지점의 매개로서 충분하다는 것이 연구자의 견해이다. 이 같은 주장의 전개를 위하여 국내에서 탄생한 온라인게임에 초점을 맞추고 국내 온라인게임의 전형이 되고 있는 핵 앤 슬래쉬(Hack & Slash) 방식과 허구적 공간에서의 게임화된 사회경험을 추구하는 스토리텔링 방식의 분석을 통해 국내형 온라인게임이 성취한 디자인 좌표를 검증하고, 이를 통해 국내 게임산업에 대두되고 있는 위기 스펙트럼과의 연관성은 어떤 것이며, 디자인은 어떠한 방향으로 매개되어야 할 것인지에 대한 의제로 접근하였다.

The purpose of this study is to analyze the expressive technique of grunge look in knitwear fashion. For this study, I have investigated theories of retro and decontructionism trends, and have examined pictures from professional fashion magazines. The results of study on the expressive technique of grunge look reflected on the knitwear fashion were as follows; (1) patchwork technique, which is an outstanding method of recycling, (2) handknitting technique, which came from retro trend of hippism, (3) unfinished edge, which emphasized the image of poverty and incompleteness, (4) irregular lace knitting and slash technique, which is the typical details of grunge look and denies the traditional fashion order, (5) hand stitch technique using various materials, which gives second-hand mood of hippie look, and (6) fringe details, which originated from the unfinished edge technique.

This paper is intended to suggest how to improve Korean high school students' awareness of the pronunciation in order to foster communicative effectiveness. Initially it is focused on the tasks of listening to the suprasegmental aspects. The strategies used in the listening process are (1)discerning intonation units, (2)recognizing rhythm pattern, and (3)identifying contraction and linking in connected speech. The tasks including in each process are listening discrimination, guided practice activity, and listening and speaking activity. The teacher should avoid methods which yield discouraging outcomes and try to help students enjoy experience of success in doing exercises and activities. So I suggested: students put the slash on the pause perceptible to chunk the stream of speech into the intonation units, and mark the content words to internalize English rhythm. And then I suggested that students listen to pop song English in order to improve the awareness of function words and connected speech in the intonation unit.
