This study investigated the size selectivity of the round traps for greenling (Hexagrammos otakii) in the western sea of Korea. The selection curve for the greenling from the experiments on Oct. 2000 and Ar. 2001 was fitted by Kitahara's method to a polynomial equation and two parameter logistic selection curve. The selectio curve of the latter was more reasonable than that of the former. The equation of selectivity curve obtained using a logistic function with least square method was , s(R)=1/1+exp(-1.1169R+6.4565), where R=1/m, and 1 and m are total length and mesh size, respectively. The size selectivity curve showed that the current regulated mesh size(35mm) in case of the round trap was close to the L50 (37.0mm) of the selection curve for the biological minimum length (21.4cm) of the greenling.

Cholpyon, a traditional Korean rice cake, was prepared using pigmented rice and the quality characteristics them were compared with Cholpyon made of brown and white ice during 24 hr storage at 20$\^{C}$. In proximate composition, crude protein contents were not significantly different among three rice varieties whereas the contents of crude lipid and ash in pigmented and brown rice were higher than that of white rice. In mechanical characteristics, 100% pigmented rice Cholpyon showed lower values for hardness, cohesiveness, springiness and chewiness, and higher value far adhesiveness compared with those of white rice Cholpyon. These results were maintained for 24 hours. Sensory Characteristics of 100% pigmented rice Cholpyon such as color, hardness and overall quality were better than those of white rice Cholpyon. Brown rice Cholpyon had similar mechanical properties to 100% pigmented rice Cholpyon, but showed the lowest preference in color.

Yukwa was prepared with the glutinous rice by the addition of different ratio of pigmented rice (0, 3, 5, 7, 10%) and were steeped for 7 days at 20$^{\circ}C$. No significant differences were found among the samples when the textural properties of Yukwa dough and base were measured using a texture analyzer. But the crispness was decreased with tile increase of the addition level of pigmented rice. The redness (a value) and yellowness (b value) of the dough and Yukwa base were increased and the lightness (L value) was decreased as the addition levels increased. The expansion rate of Yukwa was decreased with the increase of addition levels. The overall acceptability of Yukwa prepared with the addition of 7% pigmented rice was the best in the sensory evaluation.

The infection stasus of the loaches, Misgurnus anguillicaudatus, with the metacercariae of Echinostoma hortense, was studied in Korea. A total of 154 loaches purchased at 4 local markets (Seoul, Kimhae, Naju-gun and Kangjin-gun) were examined their infection rate as well as the density and location of the metacercariae in the fish body. The results are as follows: 1. The loaches carrying the metacerariae of E. hortense were 64 (41.6%) in total number and the metacercarial density ranged 1-29 per infected loach with an average value of 8.1. The highest infection rate and metacercarial density were obtained from the loaches purchased at Kangjin-gun, Jeonranam-do. 2. The metacercariae of E. hortense were chiefly distributed in the distal intestinal wall and the adjacent mesentery, the perianal tissues, and the head and gill of the loaches examined. From the results, it is concluded that the loach is one of the important second intermediate hosts of E. hortense in Korea, and their infection rate and metacercarial density are considerably high.

Fashion is a cultural element expressing general and common aesthetic awareness in a relevant region in the relevant times. On the aspect that shoes are also a part of fashion reflecting the unique aesthetic awareness of Korea, this paper aims to analyze the aesthetic awareness contained in the aesthetic features observed in the traditional boots. The aesthetic features in terms of the form were the balanced usage of each element including curves, straight lines, simple shapes, contrast colors and materials, and the application and ideological significance as the symbol of social position and status in terms of the contents. Aesthetic awareness pursues the beauty of moderation through the compromise between curves and straight lines, as both elements accept each other's features and keep balance without inclination to one element. Next, solid and void are naturally expressed by appropriately adjusting the expression on colors, materials and shapes through the harmony of composure and techniques. While traditional boots were used as the sign indicating social position and status as the unity of spirit and a thing, they pursue the value of rhythmic vitality by giving spiritual meaning to a thing.

An free-fall object is received only force of gravity. Movement that only accept gravity is free-fall movement, and a free-falling object is free falling body. In other words, free falling body is only freely falling objects under the influence of gravity, regardless of the initial state of objects movement. In this paper, we assume, ignoring the resistance of the air, and the free-fall acceleration by the height does not change within the range of the short distance in the vertical direction. Under these assumptions, we can know about time and maximum height to reach the peak point from jumping vertically upward direction, time and speed of the car return to the starting position, and time and speed when the car fall to the ground. It can be measured by jumping degree and risk of accident from car or motorcycle in telematics.
