This study examined geological characteristics of a wetland in Mountain Geumjeong in Busan Metropolitan City. Field survey and laboratory tests were performed to identify topographic features, geological and structural geological characteristics, rock strength along the distance from the wetland, soil profile in the wetland, and chemical property of the wetland soil. The bedrock of the wetland consists of hornblende granite. Hornblende granite and rhyolitic rock around the wetland have the joints with strikes of N-S, E-W, and NE-SW directions and with higher dips greater than $60^{\circ}$. Lower rock strength and higher weathering grades take place towards the wetlands. According to X-ray diffraction analysis of wetland soil samples, kaolinite, montmorillonite, and gibbsite appear which demonstrate weathered products of feldspars in the hornblende granite. The soil profile in the wetland comprises O, A, B, and C horizons from the land surface. The contents of the organic matters decrease from shallow parts to deeper parts of the soil profile. In addition, $K^+$ and $Na^+$ originating from the weathering of feldspars are dominant components among inorganic ions in the wetland soil.

Incantations are reflected in the fundamentals of the Daesoon faith system and are, thus, key to its understanding. Jeungsan, the yeonwon (fountainhead, 淵源) of the Daesoon faith, created new incantations or transformed existing ones that had been used in old religious traditions such as Buddhism and Daoism. However, there has been no in-depth academic research on Jeungsan's incantations until now. This study aims to academically clarify the incantatory archetypes of Jeungsan's incantations based on documents published until the 1970s. Jeungsan's incantations are then compared to those of Mugeuk-do (Limitless Dao) in the 1920s and Taegeuk-do (Great-Ultimate Dao) in the 1950s. Jeongsan's transformed incantations are analyzed through this process. Jeongsan reflected the faith system in Jeungsan's incantations during the period of Mugeuk-do. He transformed the incantations to achieve his goal and realize his wishes by arranging terms that referred to himself before the optative words of the incantations. Jeongsan made several changes to the incantations in the 1950s. First, the majority of incantations used in Mugeuk-do were discarded. This meant making partial changes to the faith system by reflecting awareness because the corresponding incantations were no longer necessary as the Degree Number calibrated by Jeungsan had been realized. Second, Jeongsan organized the incantations in use and institutionalized their instructions. This reflected the essential doctrinal system of the Daesoon faith, namely the completion of the true dharma by Jeongsan. Considering this doctrine, that is, the Fifty Year Holy Work (五十年工夫), the true dharma can be presumed to have been realized before the death of Jeongsan. Accordingly, the institutionalizing and organizing of the incantations were indispensable until the mid-to-late 1950s. Jeongsan, the founder of the Daesoon order, posited himself as the successor of religious orthodox lineage and as the figure who would complete the true dharma by realizing the Degree Number calibrated by Jeungsan. Therefore, Jeongsan interpreted Jeungsan's incantations to be a rough sketch of the Daesoon faith system that had been drawn for him in advance by Jeungsan. Accordingly, Jeongsan transformed Jeungsan's incantations and used them to realize the Degree Number, which Jeungsan had planned. Simultaneously, Jeongsan declared that he would fulfill the Degree Number and establish the true dharma by changing those incantations.

The purpose of this paper was to describe a statistical analysis for the spatial distribution of geographical distances of Erythronium japonicum at Mt. Geumjeong in Korea. The spatial pattern of E. japonicum was analyzed according to the nearest neighbor rule, population aggregation under different plot sizes by dispersion indices, and spatial autocorrelation. Most natural plots of E. japonicum were uniformly distributed in the forest community. Disturbed plots were aggregately distributed within 5 m × 5 m of one another. Neighboring patches of E. japonicum were predominantly 7.5~10 m apart on average. If the natural populations of E. japonicum were disturbed by human activities, then the aggregation occurred in a shorter distance than the 7.5~10 m distance scale. The Morisita index (IM) is related to the patchiness index (PAI) that showed the 2.5 m × 5 m plot had an overly steep slope at the west and south areas when the area was smaller than 5 m × 5 m. When the patch size was one 2.5 m × 5 m quadrat at the west distributed area of Mt. Geumjeong, the cluster was determined by both species characteristics and environmental factors. The comparison of Moran's I values to a logistic regression indicated that individuals in E. japonicum populations at Mt. Geumjeong could be explained by isolation by distance.

This study was carried out to provide a basic data for preservation of Pinus desiflora forest as cultural landscape forest by analyzing characteristics of plant community of P. desiflora forest in Geumjeongsan(mountatin) in Busan city. In order to analyze plant community of P. densiflora in Geumjeongsan, we set up 10 study plots inside and 8 plots outside of Geumjeongsansung(mountain fortress, hereinafter 'Sansung')(unit area: $400m^2$), a total of 18 plots. TWINSPAN analysis divided these 18 study plots into 6 communities which are Querqus serrata-P. desiflora community, P. desiflora community, P. desiflora-Q. serrata community, P. thunbergii-P. densiflora community, P. densiflora-P. thubergii-Q. acutissima community, and P. densiflora-Platycarya strobilacea community. Importance Percentage (I.P.) of each area and DBH class distribution of main species showed that P. densiflora community would succeed to Q. serrata community or C. tschonoskii community. Analysis on tree age found out that communities in the Sansung were 32~37 years old and those outside the Sansung were 44~57 years old. Shannon's species diversity index ranged from 0.4826 to 1.2499. Regarding correlation between species, P. densiflora had negative correlation with Styrax japonica. Based on abovementioned result we expected ecological succession from P. densiflora community to Q. serrata community inside of the Sansung. Outside the Sansung, succession from P. densiflora-P. thunbergii community to C. tschonoskii-Q. serrata community was expected. In order to manage P. densiflora forest as cultural landscape forest, Q. spp in the understory and shrub layer and deciduous broad-leaved arboreal trees should be managed. Tree crown management of deciduous broad-leaved trees in competition with P. desiflora, is also required.

In the past, social insurance premiums, such as national pension and national health insurance, is contained within the costs of construction projects, have been lowered due to price competition of companies participating in the bidding. The government is implementing the "Ex-post settlement system" to improve the problem. Therefore, the purpose of this study is to examine the concept of an Ex-post settlement system and background of its introduction and to identify problems in the management of the system. The problems of the Ex-post settlement system are: 1) avoiding the participation of construction workers, 2) the rigidity of the insurance premium settlement method in construction field, and 3) the cause of direct construction cost reduction. The ways to improve these problems are: 1) excluding social insurance premiums from construction project cost, 2) securing flexibility of the settlement method of insurance premiums in construction field, and 3) expanding the scope of persons eligible to participate in social insurance.

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.
