This study was carried out to give basic information about the environmental conservation in Masan District. It included the actual vegetation the degree of human disturbance of vegetation, plant biomass and biomass production. The natural vegetation was nonexistent and the major plant communities of the secondary forest was P. thunbergii-Q. acutissima and Quercus forest. P. thunbergii-Q. acutissima community area was 29.2% of Masan District and the secondary forest and the afforestation area was 48% and 13% of Masan District respectively. The ecological diversity of the plant community was high value in Q. acutissima- P. thunbergii, Q.aliena and Carpinus laxiflora-Q.variabilis communicty. As the investigation of the ecological succession in Masan Forest, P. thunbergii community is edaphic climax and mixed forest will be changed gradually dominant species of Quercus species. It was implied that Genus Quercus hadnever beenso easily taken ever by the Genus Pinus which forms the edaphic climax at vast areas of forest land. In the degree of human disturbance of vegetation, the degree 7 (secondary forest 1) was 52.8% and the green spaces in Masan cover 65%, which nongreen spaces 35 %. Total amount of plant biomass produced from Masan District was estimated to be 160, 470.95 tons. Annual Production of dry matter biomass amounts to be 32,940.64 tons. Estimated amount for O$_2$produced annually from the vegetated area in Masan was 34,856 tons.

Erosional basins formed in middle and upper reaches of Korean great rivers have been main life space of local small and middle cities, but previous studies on erosional basins are widely apart from residents' life and are in shortage with the endeavor to elucidate the man and environment relationship. This paper analyzes the factors and the modes of land-use changes of hills in the erosional basin. In this paper four erosional basins with different geological conditions are selected to elucidate the effect of geological factor(Geochang: granite, Chogye: metamorphic rock, Angye: gravelly sedimentary rock, Maseong: limestone). And the distribution of land use on the transverse and longitudinal cross-section map of the hill is described. The landscape of erosional basin is consisted of surrounding mountains, hills, dissected valleys, and incoming river's floodplain. Dissected valleys and incoming river's floodplain were reclaimed early as paddy field and hills have been used as woodland up to recently. Residents have a new appreciation of hills as a productive hill out of a traditional holy space[mountain] by influence of capitalistic thought that 'natural environment is a sort of productive resource'. Population increase is the another pressure of hill reclamation. The modes of landscape changes due to natural conditions are as follow: (1) In Geochang basin with dense tectolineament spacing, the gentle part of hill is used as field, orchard and agricultural-industrial complex site and the steep part is as woodland. (2) Hills in Angye basin with sparse tectolineament spacing are relatively flat because of maintaining a part of original denudational surface, and are used as orchids, field, paddy fields and agricultural-industrial complex site. The dissection valleys between hills are gentle concave and are used as paddy fields. (3) Hills in Maseong basin are wide and flat, and are used as fields, orchards, and agricultural-industrial complex site. (4) Because hills in Chogye basin, a closed type, are weared by affluents and are narrow and short. Hills are used as woodland and wide dissected valleys are reclaimed as paddy fields.

Objectives : The purpose of this study is to investigate the characteristics of patients referred for delirium and depressive disorder and to find direction of improvement of consultation-liason psychiatry in general hospital. Methods : We performed a retrospective computed chart review of the 4,966 inpatients hospitalized at Konkuk University Hospital who were referred to the Department of Psychiatry from August 1, 2005 to December 31, 2011. Results : Depressive disorder shows the order of frequency of consultation type Parallel-Complementary-Mending. Delirium shows the order of frequency of consultation type Mending-Parallel-Complementary. When comparing 'follow up consultation' and 'without follow up consultation' group within the depressive disorder, the proportion of men in the 'follow up consultation' group was higher. In the analysis of the consultation type, the 'follow up consultation' group showed the order of consultation type Parallel-Mending- Complementary, and type Parallel-Complementary-Mending in the 'without follow up consultation' group. When comparing 'follow up consultation' and 'without follow up consultation' group within the delirium, the proportion of the surgical field in the 'follow up consultation' group was higher. In the analysis of the consultation type, both group showed the order of consultation type Mending-Parallel- Complementary. Conclusions : Doctors in each department and psychiatrists should pay attention to delirium symptoms that may occur in surgical inpatients and preventive measures should be taken. Screening tests should be conducted in medical patients to properly evaluate coexisting psychiatric diseases. Risk factors of Delirium and Depressive disorder should be identified from the time of hospitalization, and actively discussing treatment plans and early interventions could improve the quality of medical services.
