Purpose: This study is to identify the types of role awareness of home health care specialists working at medical institutions, to understand their role awareness correctly by grasping the quality of each type, and to provide useful help in the education of home health care specialists. Method: Q-methodology is used to objectify role awareness of medical institution specialists who may recognize situations differently according to their individual experience and comprehension based on the view of behavior. Q-classification was carried out on 30 home health care specialists working at medical institutions using 30 selected questions. Collected data were examined through factor analysis using QUANL PC program. Results: Three different types of role awareness of home health care specialists working at medical institutions were identified. Type I is 'educational-function-centered', Type II 'patient-centered' and Type III 'professional-service-centered'. Conclusion: Regardless of these types, home health care specialists commonly had a high pride as a specialist and a sense of mission regarding themselves as important persons responsible for patients' health.

The purpose of this study is to investigate the structure of vegetation dominated by deciduous broad-leaved trees at the Beomeosa(Temple) Valley of Mt. Kumjungsan in Busan. To this end, 28 plots were set up and surveyed. The result analyzed by TWINSPAN, one of the classification technique, showed that the communities were divided into six groups which are Carpinus tschonoskii-Deciduous broad-leaved forest community(I), Quercus serrata-C. tschonoskii community(II), C. tschonoskii-Q.s serrata-Pinus densiflora community(III), C. tschonoskii-Quercus serrata-Q. mongolica communtiy(IV), Q. serrata-Deciduous broadleaved forest community(V) and Chamaecyparis obtusa-C. tschonoskii community (VI). Species diversity ranged from 0.3832 to 0.0450. The lowest diversity was Chamaecyparis obtusa community(VI) but the highest was Carpinus tschonoskii-Deciduous broad-leaved forest community(I) and Q. serrata-Deciduous broadleaved forest community(V). The average number of species was 6.8${\pm}$3.2 in the unit area(100$m^2$). Carpinus tschonoskii community at the Beomeosa Valley of Mt. Geumjeongsan was a climatic climax forest having a value to preserve, so a continuous management will be needed.

A survey of the Chundong valley forest in Mt. Sobaek was conducted using 20 sample plots of 500$m^2$ size. The classification by TWINSPAN and DCA, CCA ordination techniques were applied to the study area in order to classify them into several groups based on woody plants and environmental variables. By TWINSPAN techniques, the plant community were divided into four groups. The dividing groups are Pinus densiflora community, Qurcus variabilis -Q. mongolica -P. densiflora community, Fraxinus rhynchophylla community. The successional trends of tree species by DCA ordination techniques and DBH class distribution analysis seems to be from P. densiflora through Q. mongolica. Q. variabilis to F rhynchophylla. The correlation between the score of first two axes and soil pH, soil humus, soil calcium concentration, soil magnesium concentration was significantly positive in CCA ordination. The positive correlation between the score of first two axes of F. rhynchophylla community and soil humus, soil magnesium concentration and between ones of P. densiflora community and soil pH were calculated. But there is no correlation between species and environmental variables.

The purpose of the study is to understand the types and the features of the health behavior of middle-aged women in the Middle East using Q-methodology. A survey was carried out during the period from the 1st of October to the 30th of December, 2006. Data for thirty five (35) women out of forty-nine (49) were analyzed through Principal Component Analysis and WRAP (Weighted Rotational Analytical Procedure). Analysis results showed that the group was divided into four types: Type I is health management; Type II is social activity; Type III is exercise orientation; and Type IV is religious dependency. Types I, II, and III were in a positive correlation with one another, and Type IV was not correlated with the other types. Subjective perception on the health behavior of middle-aged women in the Middle East (Jordan) was investigated and compared with middle-aged Korean women. The results of this study may provide more effective ways to improve the condition of health management and to promote the quality of life.

The purpose of this study is to investigate a vegetation structure around Tongdosa temple forest and provincial park and to provide preliminary data. In order to look over the vegetation status, an actual vegetation map was drawn around study area. Vegetation structure survey was carried out for 6 representative communities of actual vegetation which were Quercus variavilis community, Carpinus tschonoskii community, Pinus densiflora community, P. densiflora-Broadleaf deciduous Forest community, Q. mongolica community and Broadleaf deciduous Forest community. The area of the Tongdosa district measured $29,202,262m^2$. Actual vegetation type were divided into 35 types, and the ratio of Q. variavilis community was 32.35 % ($9,447,932m^2$). To investigate the structure of 6 representative communities, 58 plots were set up and unit area plots measured $100m^2$. The estimated age of the forest is 50~100-years-old and the oldest tree P. densiflora is 113-years-old.

This study was intended to investigate and analyze the current status of the plant community structure in order to provide basic data for the systematic conservation and management of the Buxus sinica area appearing on the ridgeline connecting the Gyeokjabong(Mt.) and Keungiljae, on Bogildo Island. In consideration of location characteristics such as density, topography, and direction of B. sinica appearing in the shrub layers, a total of 26 sites were set as the survey area for representative vegetation communities or areas with changes in topography. According to DCA and TWINSPAN, it was classified into 6 communities, namely Carpinus turczaninovii-Deciduous broad-leaved, C. turczaninovii, C. turczaninovii-B. sinica, C. turczaninovii-Evergreen broad-leaved, Q. acuta, and D. trifidus-Q. acuta. The community dominated by C. turczaninovii maintains the status quo for the present moment, however, Q. acuta will dominate the surrounding area in the long term, so Q. acuta has high succesion potential. In the case of the Q. acuta and D. trifidus-Q. acuta communities, Q. acuta, known as the climax species of warm-temperate forests, will maintain dominant status. In a case of B. sinica, the community dominated by C. turczaninovii will remain in good status due to the topographical conditions, but the community dominated by Q. acuta growth difficulties are expected due to the high coverage. In the relationship between environmental factors and vegetation distribution, analysis showed that only soil pH affect vegetation distribution. Furthermore, the soil acidity (pH) was 3.78-5.30, the electrical conductivity was 0.186-0.543 dS/m, and the organic matter content was 2.25-2.89%.

This study was carried out to draw up the planting plan of bridge type ecological corridor for animals migration at Hakgogae(ridge) destroyed by road construction in Yongin, Gyeonggi-do, South Korea. It was conducted with two steps, survey and planting master plan. We surveyed the structure of topography, plant community, and animal habitat. We also selected the target species migrate ecological corridor and suggested a concept of each planting area, the planting species, and the planting density based on the analyzed data and finally drew up the planting plan. The structure of topography was a steep slope due to the mountain ridge destruction so the bridge type ecological corridor was could be applied in this study and we supposed that the animals migrate along the both edge of corridor. As the results of analyzed plant community structure in two sides, the dominant woody species, Quercus serrata and Q. variabilis were distributed on the bottom and the belly of a mountain, while Pinus densiflora community was distributed on the mountain ridge as edaphic climax. The similarity between Q. serrata -Q. mongolica -Q. variabilis community on the West of survey site and Q. serrata -Q. mongolica community on the East of survey site was high in 71.0 percentages. As the results of surveying birds and some mammalia, seven species and fifty-seven individuals of birds were founded in survey area, and two species and two individuals of rodents were founded. We selected birds and some mammals for the migration species that supposed to migrate ecological corridor in drawing up the planting plan. And then we divided the planting areas into bird corridor and habitat, and mammals corridor, also suggested the planting areas in detail as follows: community planting area of shrub at slope adjacent to the bridge exit as a buffer zone, screen planting area, community planting area of herb at steep slope connected with mountain areas, inducement planting area of the animals, community planting area for bird migration, community planting area for mammals migration, and community planting area for bird habitat. We selected the planting woody species which were the constancy ratio based on the analyzed data of plant community around mountain areas was high, and suggested the planting master plan each space.

In order to monitor the vegetation restoration in the evergreen broad-leaved forest, eighteen experimental plots including control plots were established at Wando Arboretum in 1996. Several treatments such as density control, selective cutting and warm temperate species planting were done in the experimental plots. Seven years after the restoration experiments, the important percentage of Quercus acuta showed a tendency to a higher increase in the experiment plots than control plots in Q. Acutu. Also the important percentage of Q. Acuta in Q. acute Carpinus tschonoskii community increased in the tree layer. Pinus densiflora community was increased highly in important percentage of Q. Acuta, As a whole, vegetation structure in the experiment plot showed successional stage to Q. Acutu community. In addition, important percentage of evergreen broad-leaved trees and shrubs and number of warm temperate species and basal area were increased in the experiment plots while the introduced evergreen broad-leaved trees were declined.

To compare ecological succession stage between 1987 and 1992, this study was executed in Mt. Puk'an. 26 sample plots of 500$m^2$ were set up. The results were summarized as follows; 1. To analysis plant community structure, the classification by TWINSPAN and CCA, DCA and RA ordination were applied to the study area. That of Mt. Puk'an was divided 4 groups by altitude. The dividing groups are Robinia pseudo-acacia-Quercus spp. community, mixed forest community, Q. serrata community, and Q. mongolica community. The successional trends of tree species over 500m seem to be from Pinus densiflora to Q. mongolica and below 500m in altitude seem to be from Robinia pseudo-acacia through Quercus acutissima, Q. mongolica, Prunus sargentii, Sorbus alnifolia to Q. serrata in the canopy layer. In the case of understory and shrub layer, the successional trends to be from Corylus sieboldiana, Zanthoxylum schinifolium through Rhus trichocarpa, Rhododendron mucronulatum, Rh. schlippenbachii to Acer pseudo-sieboldianum. 2. In comparing successional trends with 1987', the advanced data was not obtained in 1992. It was postulated that succession is not progressed by human disturbance and air pollution.
