The purpose of this study was to explore the relationship between cultural identity and the psychosocial adjustment levels of children in international marriage families by focusing on the effects that different types of cultural identity have on children's overall psychosocial adjustment. The data for this study came from a survey conducted on 122 third to sixth grades children with foreign mothers living in Seoul and Gyeonggi-Do. As a result, it was found that children's identification with Korean culture was on average higher than their identification with their mother's culture. Secondly, in terms of identity type, assimilation and separation types appeared to be the most dominant, followed by the integration and marginalization types. Finally, it was found that cultural identities had significant effects on children's psychosocial adjustment in international marriage families. In particular, the level of self-esteem was the highest for children in the integrated group, while it was the lowest for those in the marginalized group. These results indicate that identification with the mother's culture is just as important as one's Korean identity when it comes to determining the degree of psychosocial adjustment of children in international marriage families.

The present study analyzes the diversity and usage of NTFPs and evaluates their importance in the day to day life of the people of rural Meghalaya. People use 172 NTFPs belonging to 139 plant species mainly for food, medicine and fuelwood and to a lesser extent for construction, handicrafts and ornamental purpose. These 139 plants belonged to 117 genera and 70 families with Rosaceae, Poaceae and Fagaceae families as the dominant NTFP yielding families. Fruits from shrubs and trees are most commonly harvested by people. Collection and availability of NTFPs for use as food are more during the summer season, which is also the period with least availability of job. NTFPs for subsistence use are greater in number than those having commercial value. The most commonly harvested plant parts are fruits and leaves. Roots, rhizomes and whole plants are extracted in lesser quantity which is a positive approach from sustainability point of view. NTFPs and other forest products also form a vital part of the rural household's income generation activities.

Investigated was the ground-walking Coleoptera at the moor and adjacent forest at 800 m and rice paddies at lower level of 50 m in altitude. There were 5 species belonging to 5 genera and 2 families, 4 species belonging to 4 genera and 3 families, and 17 species belonging to 11 genera and 2 families respectively. Diplous depressus (Gebler) was the dominant species at the moor and forest in distinctive numbers, while Pheropsophus javanus (Dejean) was the one at the paddies. Three investigated sites supported independently their ground-walking Coleoptera groups. The moor group seemed to fail in establishing the resident Coleoptera community. The fact may imply to be related a kind of the pioneer species in early dry succession that D. depressus was found in a considerable range between forest and moor. The Coleoptera groups of moor and forest was different from that of paddies in species structure.

An ecological survey on the vegetation of Poong Island was conducted for 2 days from August 19 through 20, 1981 and the results obtained are summarized as follows: Flora of this island consist of 65 families, 157 genera, 167 species, 27 varieties and 3 forma of which herbs are classified into 38 families, 98 genera, 98 species, 20 varieties, 2 forma and trees into 33 families, 61 genera, 69 species, 7 varieties and 1 forma. Evergreen broad-leaved trees are scanty in distribution and only Eionymus japonia thunb. and Euonymus forannei var. radicans (Sieb. et Miq) Rehder are observed. The dominant species of this island is Pinus densiflora. Due to the low density of population (149.8) and low pure farming rate of this island, the destruction of nature is rarely to be noticed and therefore natural vegetation may be considered to have been well preserved.

A study on the distribution and community structure of benthic macroinvertebrates on the intertidal zone of Cheju Island was carried out from June 1988 to May 1989. The macroinvertebrates collected and identified were composed of 7 phyla, 14 classes, 29 orders, 71 families and 135 species in this study. The dominant species of the upper tidal zone were Nodilittorina granularis and Heminerita japonica, those of the middle tidal zone were Monodonta neritoides and Lunella coronata coreensis, However, Monodonta neritoides and Chlorostoma arhyrostoma lischkei were dominant in the lower tidal zone. Community dominant indices were significantly high in the upper tidal zone. Macuoinvertebrates species which have the ability of resistance to the physical factors such as, strong waves and exposure to the hot sunlight were mainly distributed on the intertidal zone of Cheju Island. The difference in the number of species among seasons was not significant, but thao among zones was quite apparent and the lower the zone, the more abundant.

The ichthyofauna of Lake Cheongpyeong was investigated from April 2003 to November 2004. During the surveyed period 31 species belonging to nine families were collected. Dominant species in numbers was Hemibarbus labeo (relative abundance: 29.9%), subdominant was Acanthorhodeus gracilis (22.8%). Erythroculter erythropterus (14.6%) and Cyprinus auratus (6.3%) were also numerous. There were nine Korean endemic species belonging to three families, including Acheilgnathus yamatsutae. We need close observation on population fluctuations of Micropterus salmoides, an exotic carnivorous fish from North America, and Hemibarbus labeo and Erythroculter erythropterus, the dominant species by biomass in Lake Cheongpyeong.

Species composition, life form, biomass and soil properties of the halophyte communities were investigated from July to September, 1982. At the reclaimed land of Sanho-ri, sand dune of Jido, salt marsh of Suncheon Bay, and Somjin River estuary of Baealdo, species numbers were 26, 14, 13 and 7, dominant species were Salicornia herbaceae, Carex pumila and Suaeda japonica, respectively. Species composition of the 4 investigated areas was 13 families, 25 genera and 39 species, and of them, 10 families, 21 genera and 24 species were attributed to halophytes. Out of 22 life forms, the representative for Jido was $ G-D_4-R_1-3-e.t$and those for the other sites were Th-G4-R5-e. Above ground biomass of all species for Sanho-ri, Jido, Suncheon Bay and Baealdo were 441.3, 202.0, 150.7 and 353.3 g.dw/m2 and the ratios of above ground biomass halophytes to all species were 93.5, 92.7, 90.8 and 100%, respectively. The leading dominant species formed a continuum according to the salt gradiant. The similarity between Baealo and Suncheon Bay was relatively high, and Jido was quite different from the others in species composition. Aster tripolium was stenohaline and appeared at the low salt concentration, but Suaeda maritima and Suaeda asparagoides were duryhaline and occured at the relatively high salt concentration.

The structure of the nematodes communities has been studied in the sediments on two sites located outside and under the layer of Ahnfeltia tobuchiensis (Kanno and Matsubara 1932; Makijenko 1970). Bottom sediments at the stations were represented by sands with a different degree of silting. Specific structure of nematodes at the stations was significantly different under the similar environmental conditions (water depth, dissolved oxygen saturation, salinity, temperature of the bottom layer and organic carbon content inside of the sediment). Nematodes dominated (75.7 %) in meiobenthos community under the layer of A. tobuchiensis where concentration of silt particles was 12 %. Representatives of the family Comesomatidae were dominant. Low index of species diversity and high Simpson domination index were detected in this community. Under a layer of A. tobuchiensis with the thickness of 30 cm concentration of the silt particles was 5.39 %; nematodes density was low and made 32.1 % of the general density of meiobenthos. Species of the families Xyalidae and Monoposthiidae were dominant. Outside of A. tobuchiensis, field percentage of silt particles was minimal (3.1 %) and representatives of families Cyatholaimidae and Axonolaimidae dominated. The specific structure of nematodes in this type of the ground is characterized by high index of species diversity and low level of domination.
