The costume style of the Chosun dynasty changed greatly after Imjinwaeran (the Japanese Invasion of Chosun Korea, 1592∼1598). Most of the extant costumes come from the late Chosun, but some costumes produced be-fore Imjinwaeran have been excavated, and in addition, information on these older constumes is contained in contemporary literature. Of especial value in the study of pre-Imjinwaeran Chosun constumes is a mid-sixteenth century palace painting depicting the worship of Buddha, a painting in the collection of the Ho-Am Art Museum in Seoul. The present study of costume during the middle Chosun dynasty focuses on this painting, and compares it with other contemporary palace paintings, and with other contemporary palace paintings, and with Nectar Ritual Paintings. The following conclusion were drawn : * Concerning woman's hair styles of the time, married women wore a large wig. Un-married women braided their hair, and then either let it fall down their back or wore it coiled on top of their head. * The major characteristic of woman's costumes was a ample, tube-like silhouette, with the ratio of the Jeogori(Korean woman's jacket) and skirt being one-to-one. * The style of Jeogori in the painting was like that of excavated remains. Some Jeogoris were simple (without decoration), while some Jeogoris were worn with red sashes. Here we can confirm the continuity of ancient Korean costumes with those of the sixteenth century * Although the skirt covered the ankles, it did not touch the ground. Because the breadth of the skirt was not wide, it seems to have been for ordinary use. Colors of skirts were mainly white or light blue. * All men in the painting wore a headdress. Ordinary men, not Buddhist monks, wore Bok-du (headstring), Chorip (straw hat), or Heuk-rip (black hat). In this painting, men wore a Heukrip which had a round Mojeong (crown). * The men wore sashes fastened around their waist to close their coats, which was different from the late Chosun, in which men bound their sashes around their chest. That gave a ration of the bodice of the coat to the length of the skirt of one-to-one, which was consistent with that of woman's clothing. * In this painting, we cannot see the Buddhist monk's headdress that appeared later in the Chosun, such as Gokkal (peaked hat), Songnak (nun's hat), and Gamtu (horsehair cap). These kinds of headdresses, which appeared in paintings from the seventeenth century, were worn widely inside or outside the home. Buddhist monks wore a light blue long coat, called Jangsam (Buddhist monk's robe) and wore Gasa (Buddhist monk's cope), a kind of ceremonial wrap, round their body. We can see that the Gasa was very splendid in the early years of the Chosun dynasty, a continuing tradition of Buddhist monk's costumes from the Koryo dynasty.

The experiment was conducted to know the varietal difference in changing aspect of daily filling sink during of rice using three cultivars; ‘Suweon 295’ (japonica), ‘Suwoen 264’ and ‘IR 1317-70-1’ (semi-dwarf indica) cultivated in the field and green house of the Crop Experiment Station in 1983. There was not significant varietal difference in flowering habit and duration of flowering period each panicle. Semi-dwarf indica cultivars showed shorter days to physiological maturity of rice kernel than the japonica one. The former also displayed earlier decrease in water content of rice grain during ripening than the latter. Japonica variety revealed larger difference in ripening advancement between vigorous florets and inferior one than semi-dwarf indica varieties. The semi-dwarf indica rice cultivars expressed significantly shrewder parabola of daily filling of sink per panicle during ripening than the japonica one. The time showing maximum capacity of daily filling of sink per panicle during ripening was 10-12 days after anthesis. The filling capacity of daily sink filling per panicle for 'IR 1317-70-1', 'Suweon 264' and 'Suweon 265' at this time were about 240 mg, 165 mg and 145 mg, respectively. Pattern of sink filling per panicle during ripening was slightly changed by the cultural environment. ‘Suweon 295’ showed slightly sharper parabola and 2-3 days earlier time showing maximum capcity of daily sink demand per panicle during ripening in the field than those in the green house.

The objective of this study was to investigate the site and growth characteristics of dominating Cornus controversa in the hardwood stands at Mt. Gariwang and Mt. Joongwang area located in Pyungchang-gun, Kangwon-do. The C. controversa was mainly distributed at the rather steep slope and aspect facing from northeast to northwest, and altitudes ranging from 800 to 1,100m. The C. controversa grew at relatively deep A soil layer with high moisture and nutrients. Major competing species in upper stories were Quercus mongolica, Acer mandshuricum, Salix hulteni, Acer pictum, and herb plants such as Polystichum tripteron, Dryopteris crassirhizoma, Meehania urticifolia, Pseudostellaria pahbiniana, Ligularia fischeri, Impatiens noli-tangere, Corydalis speciosa in the floor. The average annual diameter growth of C. controversa according to the altitude was $4.06({\pm}0.90)mm$ below 900m, $2.51({\pm}0.65)mm$ from 900 to 1,000m, $3.28({\pm}0.12)mm$ from 1,000m to 1,100m and $2.81({\pm}0.35)mm$ above 1,100m. Good annual growth was shown at northwest site, but no difference due to micro-topography.

As breast cancer shows the highest incidence among women's cancers, the use of mammography is also increasing as a screening test. Mammography should produce high-quality images for accurate diagnosis. For this, it is necessary to manage the performance and image quality of mammography. Thus, in order to investigate quality control, the present study conducted a questionnaire survey of 37 hospitals registered as breast cancer medical examination centers in Gwang-Ju, concerning their quality control of mammography. In the results of surveying the characteristics of apparatus use for mammography, many respondents did not know about the equipment that they were using. Of the hospitals, 19 (49%) were using film, 19 (49%) CR, and 1 DR. In the results of asking how to do quality control, only 38% answered that they inspected according to the manual. In addition, all the surveyed hospitals had specialized agencies do quality control for them. As to the reason for using agencies, 65% mentioned limitations in personnel, time, distance, etc, and 44% mentioned the absence of machines and materials. These results suggest that quality control is being performed perfunctorily, as well as passively and indifferently as it relies on specialized agencies. Accordingly, it is necessary to provide regular education for enhancing people's perception of quality control and to perform quality control adequately in the presence of Radiologist.

The present study used one of research techniques which is eye gaze tracking for neuromarketing. When pupil's size of men dilated over than three sigma (0.135%), the interest and eye movement in observation were measured. According to statistical analysis of previous studies, three sigma range is meaningful therefore sigma range was used as operational definition because 'pupil dilatation' is difficult to be define in eye gaze tracking data. Pictures of basketball games were selected as visual stimuli and 90% effective ratio of total 7,200 data were calculated. Thus, 29 of 34 participants were used for test. Pupil's size was calculated by applying pupil's width and height into a formular; [Pupil's size = Pupil width/2${\times}$Pupil height/$2{\times}{\pi}$]. In conclusion, billboard utilized for sports marketing had meaningless effects because gaze frequency to basketball player and surrounding environment was higher than that to billboard when participantsas game spectators diltaed their pupil's size over than three sigma. Thus, it was required using new marketing strategies like neuromarketing to increase utility through the present study.

The aim of this study was to characterize the forest vegetation and site of Tongdaesan(Odaesan National Park) for ecological forest management. The deciduous forests of Tongdaesan are the result of cool, temperate climate. Direction and slope morphology contribute to differences in species composition and vegetaion structure. Based on the BRAUN-BLANQUET-approach, 242 releves were recorded and subsequently classified. The vegetation could be divided into two forest community groups, seven forest communities, and several groups. South exposed, dry slopes were covered with forests of the Quercus mongolica-Acer pseudo-sieboldianum community group. Differential species included grasses and sedges, e.g., Calamagrostis langsdorfii, Carex humilis and C. lanceolata. Quercus mongolica-Acer pseudo-sieboldianum community group could be subdivided into Rhododendron mucronulatum var. ciliatum community, Lespedeza${\times}$tomentella community, Carex humilis-Maackia amurensis community, Quercus mongolica-Acer pseudosieboldianum typical community and Pimpinella brachycarpa community. Carex humilis-Maackia amurensis community was divided into Galium kinuta subcommunity and typical subcommunity. Pimpinella brachycarpa community was divided into Vicia venosa var. cuspidata subcommunity and typical subcommunity. On north exposed, more humid and moist sites, forests of the Dryopteris crassirhizoma-Cornus controversa community group were found. This group was subdivided into Acer tschonoskii var. rubripes-Acer tegmentosum community and Deutzia glabrata-Ulmus laciniata community. Deutzia glabrata-Ulmus laciniata community was divided into Acer tegmentosum subcommunity, Saxifraga punctata subcommunity and typical subcommunity.

People generally focus on the supply side when conducting a study on the movie industry. However, to understand the movie industry better, one needs to analyze both sides - the demand and supply of movies. This paper analyzes demand-side factors that have long been taken for granted in Korea's movie industry. The study used data for 1991~2008 on the following demand-factors : the average ticket prices, the number of working days and hours, the average personal income, the number of spectators for the two major professional sports, cable TV, the number of movies released each year and the number of movie screens. This study shows that ticket prices do not conform to the law of demand. According to the law of demand, increasing price leads to a decline in demand. However, in reality, the number of viewers went up along with ticket prices. The study found that demand for movies was correlated to income levels and leisure time. An increase in the number of leisure hours and income levels pushed up demand. Contrary to general belief, a growth in the availability of substitutes, such as professional sports(soccer and baseball), did not result in a fall in demand for movies. The audiences for both sports and movies grew simultaneously as the amount of leisure time increased. Contrary to the general expectations that more diversified genres of movies will draw larger audiences by satisfying different individual tastes, the diversification had little impact, but the number of movie screens was positively correlated with audience size. In sum, changes in ticket prices and the quantity of substitutes had little influence on demand in the movie industry. Rather, it was the supply side of the industry that induced demand.
