The purpose of this study is to investigate the relationship between the development of laterality and bilateral motor abilities measured with respect to various rhythm movements in upper extremity of mentally retared children. The development of laterality was measured by a survey of dominace-hand. The bilateral motor abilities were assessed by means of a tentative rhythm beat test of hands. One hundred sixty eighty subjects with special education needs shose age ranged from 7 to 18 years old were used for an experimental group. Fity nine normal children whose age ranged from 3 to 6 years old were also chosen as a control group. The major findings were a follows: 1. The development of lateral dominace-hand in mentally retared children differed from that of normal subjects with as increase in chronological age; the degree of the attainment of lateral dominance - hand was 75 percest of the mean level of the normal children. Though normal children establish a dominance - hand by ths age of years old, meatally retarded children are likely to show 57 percent of normal development at the age of 7 through 9 years old and 65 percent of normal development at the age of 16 through 18 years old. 2. A greater delay in mentally retarded was found through a rhythm test which was development to assess bilateral motor abilities in upper extremity. A closser relationship betwin chronological age and the development of bilateral motor abilities in mentally retared children was found. 3. In view of these findings, it was indicated that bilateral motor abilities of the retarded and non-retarded children were significantly correlated to the acqusition of dominance-hand.

In order to determine whether foals of move dominant mothers were harassed less by mares than those of lower-ranked mothers, harassment of foals was studied in a herd of Jeju ponies (Equus caballus) consisting of 73 mares, their 53 foals, and one stallion. Mares Harassed the foals on 71 occasions between March to September,1998. The frequency of harassment tended to decrease as foals aged, but the relationship was not significant (P = 0.079). Foals were harassed when sleeping (n = 14), grazing (n = 19), moving (n = 8), approaching a mare in the vicinity (n = 13), or play-fighting with the foal of the harassing mare (n = 17). Mares harassed foals of younger, more subordinate mares than those of older, more dominant mares (P < 0.001). We conclude that early social experience of foals is associated with the dominance rank of its mother.

In this paper, we identified factors that affect the usage of UCC, which is becoming increasingly popular in our society and throughout the globe. Four hypotheses were tested using a new integrative model of UCC usage, which is built up by incorporating the TAM and the PAD(pleasure-arousal-dominace)model. We analyzed the data collected in our survey of 258 individual UCC users during the period from Oct 2006 to Dec 2006. We found that pleasure and arousal showed a strong significant effect on individual's UCC usage, supporting the findings of the exiting research on TAM. To be specific, arousal had an effect on the UCC usage through its effect on pleasure and self efficacy. Pleasure affected the UCC usage in two ways: First, pleasure affected UCC usage through increasing the ease of UCC service. At the same time, pleasure had a direct effect on the UCC usage. Contrary to what the prior research on technology acceptance suggested, we found ease of use and social influence had no significant effect on individual's UCC usage. We further found that such effects of the ease of use and pleasure factors are more positive in the entertainment-based UCC than in the relationship-based UCC.

The purpose of the study was to introduce the fish fauna and distribution in the Shinpo district, North Korea. Sampling was carried out in October 1997, July 1998, May and October 2002, in sites located in the upstream, middle and down of the southern river of Bukcheong and three brackish lakes of Hommanpo, Daein and Hyunkum, respectively. A total of 29 species belonging to 11 families were found. Family Cyprinidae showed the prosperity in species number, comprising 28% among total species found. No natural monument fishes or rare fishes were captured. Ten commercial species, five anadromous ones and five brackish ones were identified. Feeding guilds was identified as 11 carnivores, 2 herbivores and 7 omnivores. Twenty species belonging to 7 families inhabited in the river, 18 species of 6 families in Lake Homanpo, 21 of 7 in Lake Hyunkum and 23 of 8 in Lake Daein, respectively. Ecological indices of richness, diversity and evenness were highest in Lake Daein and the dominace index was highest in Lake Hyunkum.

Physicochemical environments and phytoplankton community in the nakdong river middle basin were investigated during a period of 1 year from Nov. 1993 to Oct. 1994. The ranges of Physicochemical environment factors in the nakdong river middle basin were $3.6~27.4{\circ}C$ for temperature, 7.1~9.3 for pH, $7.1~12.7mg/{\ell}$for DO, $0.7~2.1mg/{\ell}$ for BOD, $31~52mg/{\ell}$ for alkalinity, $2.101~3.3mg/{\ell}$ for T-N, $0.052~0.099mg/{\ell}$ for T-p, $5.4~92.3mg/m^{3}$ for chlorophyll-a. The number of Phytoplankton was lowest in Jan. that is, 244ce11s/ml and that was highest in Sep. 1201 cells/ml. The increase of dominant genera were correlated with the total nomber of phytoplanktons. Bacillariaceae, chlorophyceae, cyanophyceae, and euglenophlrceae were to 74.5%, 20%, 3.5%, and 2.2% respectively. Bacillariaceae were abundant during all the year round except for Jun, Jul, Aug. Chlorophyceae were plentiful in Jun, Jul, Aug. Tase-and odor-causing algae and filter clogging algae were 72% in Nov. and 93.5% in Jun. They were abundant all the year round except for winter, so they influenced on the treatment of tap water system. They belong to the general asterionella, cyclotella, melosira, nitzschia of bacillariaceae and actinastrum, pediastrum of chlorophyceae. Dominace index was low in winter and high in umber. Diversity index and equitability index were low in summer and high in winter. Therefore, the structure of phytoplankton community of the nakdong river middle basin was different form season to season.

The parents and F$_1$ seeds from the all possible combinations of the diallel crosses among five upland varieties and a low-land variety were grown in green house in winter and also on paddy field in summer. The durations to heading of all F$_1$'s grown in green house at winter were shorter than those of their parents mean. The shorter duration to heading was due to dominace was partial. And the non-allelic gene interaction was not significant. But in case that the F$_1$'s and the parents were grown on paddy-field in summer. the durations to heading of F$_1$'s were various according to the cross combinations and the non-allelic gene interactions were significant.

Genetic analysis of body pigmentation pattern has been conducted by the reciprocal monohybrid and back crosses using the wild type zebrafish, Danio rerio, and its aquarium morphs (mutants), leopard danio. Also, the effect fo pigmentation mutation was investigated with regard to the survival rates of eggs and larvae for the first 15 days after fertilization. As a result, the pattern pigment distribution was inherited by a single gene having two alleles, and which was basically followed by the principle of dominace and segregaion in Mendelian inheritance. A locus for pigment pattern turned out to be located on an autosomal chromosome. Average survival rates estimated from the various crosses between, and within, wild type zebrafish and leopard danio were as follows ; they were 80.6${\pm}$4.8% from the crosses within leopard danios ($L{\times}L$), 70.6${\pm}$4.2% between leopard female and wild type male ($L{\times}Z$), 73.2${\pm}$2.0% between wild type female and leopard male ($Z{\times}L$), and 83.8${\pm}$6.7% within wild type zebrafish ($Z{\times}Z$). These results indicated that the leopard danio, which were reported as an "aquarium morph" several decades ago and also known as a mutant in pigmentation pattern of the wild type zebrafish, seemed to be genetically stable like the wild type of zebrafish.zebrafish.

In this paper, we propose new method to reduce variance and express mixed feelings in Russell's emotional dimension(A Circumplex model). A Circumplex model shows mean and variance of emotions(joy, sad, happy, enjoy et. al.) in PAD(Pleasure, Arousal, Dominace, et. al.) dimension using self-diagnostic method(SAM: Self-Assessment-Manikin). But other researchers consistently insisted that Russell's model had two problems. First, data(emotional words) gathered by Russell's method have too big variance. So, it is difficult to separate valid value. Second, Russell's model can not properly represent mixed feelings because it has structural problem(It has a single Pleasure dimension). In order to solve these problems, we change survey methods, so that we reduce value of variance. And then we conduct survey(which can induce mixed feelings) to prove Positive/Negative(Pleasure) part in emotion and confirm that Russell's model can be used to express mixed feelings. Using this method, we can obtain high reliability and accuracy of data and Russell's model can be applied in many other fields such as bio-signal, mixed feelings, realistic broadcasting, et. al.
