In virtual environments, such as computer game and animation, we need to enhance naturalness of crowd simulation. So, we propose a method to generate dynamically moving crowd patterns by applying emotional factors to the individual characters of a crowd in the determination of their behavior. The proposed method mimics human behavior and controls each character in a group to decide its own path according to its individual status. And it is able to generate various moving patterns as a result of letting the individuals go to another group depending upon their conditions. In this paper, some temperament and feeling factors are defined and determination rules for calculating the emotional status are also proposed. Moreover we use a fuzzy theory for accurate representation of the ambiguous expressions such as feeling bad, feeling good and so on. Our experiments show that the suggested method can simulate virtual crowd in more natural and diverse ways.

The purpose of the study was to develop a computer access assessment system for improving computer access of individuals with physical disabilities for the first time in Korea. Korea-Computer Access Assessment System (K-CAAS) presented in this article tests five user skills of aim, drag, menu, scan, and switch. Skill levels of the five test areas could be set as low, middle, and high according to individuals' characteristics. All tests have their default set in each level, and skill levels can be selected and controlled by the abilities and goals of a user. Tests could be selected for users' training and their results could be traced and shown. Therefore, the K-CAAS is a training program to improve computer access skills as well as an assessing program. It would help users with physical disabilities operate a computer by themselves as improving their computer access skills.

This study has expanded the existing studies on the characteristics of consumers using the personal level of cultural dimensions and self-construal. As Korean are becoming more individualistic and independent, we have focused on consumer independence in self-construal. The purpose of this study was to investigate the effects of consumer independence on consumers' attitudes and purchase intention toward consensus claim in ads. We hypothesized that individuals with higher in independence are more likely to show negative attitudes and the purchase intention towards the ads focused on consensus claim. Two experiments revealed that consumers higher in independence, depicting consensus claim in ads reduces consumers' attitudes and purchase intention. Based on the results, we suggest that for individuals higher in independence, consensus claims in product advertisement are less effective advertising strategy which ultimately lower consumers' purchase intentions. Important theoretical and practical implications are discussed.

Main purpose of this study is to analyze determinants of household debt among middle and old individuals aged between 32 and 76 that include Korean baby-boomers(born between 1955 and 1963), using a HAPC (Hierarchical Age-Period-Cohort) model and Korean Welfare Panel Study 2006-2016. This study includes 86,056 individuals. Research findings indicate that aging and period effects have statistically significant relationships with household debt levels, however, cohort effects including a baby-boomer generation do not. While household debt increases by 3,530,000 Korean won as age increases by one year, the rate of increase in household debt reduces as individual ages. In addition, employment and health status at the individual level have significant effects on household debt levels. The unemployed are more likely than the employed to have high household debt levels while unhealthy people tend than healthy people to have high household debt levels.

The relationship between floristic composition and soil environmental factors was investigated in the forest vegetation of Mt. Mohu.The forest vegetation unit of the Mt. Mohu could be divided into three communities, Quercus mongolica community, Pinus densiflora community and Quercus variabilis community. There were two subcommunities in Quercus mongolica community, which were Rhododendron schlippcubachii subcommunity and Stephanandra incisa subcommunity. The Quercus mongolica community was distributed at the altitude of 600~900 m, Pinus densiflora and Quercus variabilis communities were distributed on south-west slope at the altitudes of 430~520 m and 400~500 m, respectively.The DBH class of dominant species in each community showed that Quercus mongolica had 9 individuals/a at 11~15 cm class, Quercus variabilis 5.6 individuals/a at 11~15 cm class, and Pinus densiflora 8 individuals/a at 16~20 cm class. Quercus mongolica. Quercus variabilis and Pinus densiflora communities showed a bell-shape distribution.The contents of organic matter and soil water, and cation exchange capacity of the soil increased and the pH decreased in proportion to increased altitude. The soil environmental conditions of Quercus mongolica community were more favorable than those of Pinus densiflora and Quercus variabilis communities.The supposed successional sere of the forest vegetation of Mt. Mohu was as follows: Pinus densiflora community.Quercus variabilis community.Quercus mongolica community

The diet of the walleye pollock Gadus chalcogrammus, was studied by examining the stomach contents of 864 individuals. Using gill nets, samples were collected monthly from January to December 2017 in Jugwang, Sokcho, Yangyang, Uljin, Ganggu, and Gampo, Korea. The specimens ranged in total length (TL) from 16.6 to 75.2 cm. G. chalcogrammus fed mainly on Euphausia pacifica (Euphausiacea) and less on Cephalopoda, Pisces, Mysidacea, and Macrura. The results indicated that G. chalcogrammus is a specialist feeder, feeding mainly Euphausiacea. With growth, however, its diet shifted from Euphausiacea to Cephalopoda, Macrura and Pisces. Smaller individuals (<40.0 cm TL) consumed mainly Euphausiacea. The proportion of Euphausiacea decreased with increasing body size, whereas the consumption of Cephalopoda and Macrura increased gradually.

The feeding habits of Hoplobrotula armata were studied using 269 specimens collected in the coastal waters of Geomun-do, Korea. The size of the specimens ranged from 5.6-56.8 cm in total length (TL). H. armata is a canivore that consumes mainly teleosts and decapods (shrimp, crabs and hermit crabs). Its diet also includes gammarid amphipods, cephalopods, polychaetes and copepods. Smaller individuals (<20 cm TL) fed mainly on fish, shrimp and crabs. The proportion of shrimp and crabs decreased as body size increased, whereas the consumption of fish gradually increased. Fish accounted for almost the entire stomach contents of individuals (larger than 40 cm TL).

Ecological characteristics of Orthrias nudus from the Eoron Stream, Gangwon-do, Korea were investigated from January to December 2009. O. nudus inhabits mainly riffles of the upstream and mid-upstream stretches of Eoron Stream, which were composed of boulder and cobble bottoms. The current velocities in these habitats were 0.42~1.34 m/sec and depths were 15~46 cm. The sex ratio of female to male was 1 : 0.98. It is presumed that the spawning season is from April to June when water temperatures were $15{\sim}19.2^{\circ}C$. Sexually mature individuals appeared to be over one year of age. Frequency analysis of total length indicated that the group 58~99 mm in total length is represented by one-year-old individuals, and the group over 100 mm by two-year-old individuals. The average number of eggs in the ovaries was estimated as 4,119 per mature female. Stomach contents of O. nudus were composed of aquatic insects such as Ephemeroptera, Trichoptera and Diptera.

The feeding habits of Paralichthys olivaceus in the Uljin marine ranching area, located on the mid-eastern coast of Korea, were studied from January to November 2009. In total, 381 specimens were collected; fish ranged in size from 15.4 to 59.0 cm in total length. P. olivaceus is a carnivore, mainly consuming other fishes and crustaceans. The prey items of P. olivaceus changed ontogenetically. Small individuals fed on decapod crustaceans while large ones fed heavily on other fishes. The diet of P. olivaceus varied seasonally. Fish comprised the main prey items throughout the year. The stomach contents index (SCI) of each size class increased and the dietary breadth index (DBI) of each size class decreased as individuals grew.
