It is not uncommon in Korea to see the structure and function of a garden remain intact as well as its form. Yi Cheon-bo's Historic House (Gyeonggi-do Cultural Heritage Item No. 55), located in Sang-myeon, Gapyeong-gun, Gyeonggi-do, is considered an example of very valuable garden heritage, although its family history, location, and remaining buildings and natural cultural assets are not fully intact. Along with Yi Cheon-bo's Historic House, this study attempted to explore the possibility of restoration of the forest houses and gardens by highlighting the high value of Yi Cheon-bo's Historic House through research into the typical layout of private households in northern Gyeonggi Province and Gapyeong County, comparative review of aerial photographs from 1954, and interviews with those involved. The results of the study are as follows: In this study, the presence of Banggye-dongmun and Bansukam in the Banggyecheon area, where the location of the garden was well-preserved, was examined across the landscape of the outer garden, while the location of Yi Cheon-bo's Historic House, the appearance of feng shui, and the viewing axis were considered. Also, the appearance of the lost main house was inferred from the arrangement and shape of the Sarangchae and Haengrangchae that remain in the original garden, and the asymmetry of the Sarangchae Numaru and the hapgak shape on the side of the roof. In addition, the three tablets (Pyeonaeks) of Sanggodang (尙古堂), Bangyejeongsa (磻溪精舍), and Okgyeongsanbang (玉聲山房) were used to infer the landscape, use, and symbolism of the men's quarters. Also, a survey was conducted on the trees that existed or existed in the high prices. Incidentally, it was confirmed that information on boards and cultural properties of Yeonha-ri juniper (Gyeonggi-do Monument No. 61) was recorded to a much lesser extent than the actual required standard, and the juniper trees remaining in the front of Haengrangchae should also be re-evaluated after speculation. On the other hand, as a result of estimating the original shape as a way of pursuing completeness of the garden through restoration of the lost women's quarters and shrine, it is estimated that the main house was placed in the form of a '口' or a 'be warped 口' on the right (north) side of the men's quarters. By synthesizing these results, a restoration alternative for Yi Cheon-bo's Historic House was suggested.

In 1995, the costumes were restored in an unknown woman's tomb at the Jeonju Lee's family cemetery in Gapyeong, Gyeonggi-Do, and there are currently nine items remaining. In this study, we first introduced these 9 relics to academia and analyzed the morphological characteristics of the costumes. We also estimated the time and person of burial compared with costumes unearthed from other burials. Jeogories (short jacket) are all four items. One of these items was unusual in shape, and the upper part of the seop (gusset) was wrinkled and shaped. This type of Jeogori appears only till the 1520s in other tombs. There are also two skirts, one of which is characterized by a superimposed pattern. The top and bottom / middle part of the skirt were rolled up, and the skirt, which was double-rolled up in this way, was first discovered. An analysis of the shape of Jeogori and skirt indicated that the person buried in the Jeonju Lee's family tomb was believed to have survived until the early 16th century. Based on these estimated periods, as a result of looking at the genealogy of Jeonju Lee's family, it was concluded that the tomb was probably a woman named Lee Geum Myeong (李金命) born in the mid-15C and died between the late 15C and the early 16C.

Buddha painting cultural properties couldn't avoid the change of colors and the exfoliation phenomenon by the characteristic of material and environmental factors. Especially, because in the beginning of the fine crack and the decoloration phenomenon on the surface of pigment would be significantly decrease stability of the whole object, it is necessary to take particular measure. Therefore, this is a study on conservation of Avalokitesvara in Potalaka in Hyeondeungsa in Gapyeong. It treated damaged parts of the object, carried out backing papers and matching colors. And then, it examined scientific analysis of pigments. Also, it performed nondestructive testing like XRF, FT-IR, and image microscope to investigate the quality of the material of hanji using the object and the component and characteristic of pigments. As a result, FT-IR spectrum matching Korean traditional paper(hanji) was detected in hanji of Avalokitesvara in Potalaka in Hyeondeungsa. The black pigment making a thin layer over the white pigment would estimate carbon compounds of unconfirmed ink stick or soot as XRF and FT-IR. Also, the white pigment was lead white($PbCO_3{\cdot}Pb(OH)_2$) involving Pb(Lead) and a carbonate. It was observed that the crystal of blue pigment had the different sizes of the particles from the microscope. In the case of this blue pigment, it showed cobalt blue and lead white was mixed when it used because both Cu and Pb were highly detected in XRF data.

April, 2005 to October, 2013. The collected species during the survey period were 17 species belonging to 6 families. Dominant species was Zacco koreanus(Relative abundance 59.9%) and subdominant species Pungtungia herzi(8.5%). Korea endemic species were 12, including Coreoleuciscus splendidus. The species of Hemibarbus mylodon was identified as natural monument, and Pseudopungtungia tenuicorpa and Gobiobotia brevibarba were endangered species. Water quality assessment of Gapyeong Stream, had lately maintained the rating of "very good" for nine years, based on the Ministry of the Environment standards notice. It was found that there was a tendency for populations which is Coreoperca herzi carnivorous species decreases, increases omnivorous species Zacco platypus. As a result of community analysis, dominant index was 0.58~0.86, diversity index was 0.94~1.77 and richness index was 0.99~2.39. As a result of using the Rarefaction curve, were analyzed occurrence species expected each year, number of species is estimated from a sample of 151 individuals, up to 12(2005) was at least 5(2007) species. The regression coefficient (b) in relation to length-weight on Z. koreanus population were annual average $3.29{\pm}1.11$, condition factor slope $0.0034{\pm}0.0021$, which maintained good growth condition and stabilized population.

Occurrence of earthworms for turfgrass growing seasons and effect of earthworms by some plant extracts and plant oils in golf courses were investigated at the three locations golf courses in Korea 2005 to 2006. There were no differences in monthly occurrence of earthworm except Anseong Benest Golf Club, namely, Anseong Benest Golf Club was highly occurred in July in 2006. Density of earthworm was not different between fairway and rough in Dongrae Benest Golf Club (opened in 1971) while density was higher in rough than fairway in Anseong Benest Golf Club (opened in 1999) and Gapyeong Benest Golf Club (opened in 2000). In case of Gapyeong Benest Golf Club, earthworm density was higher in old courses than recently opened courses. Effect of plant extracts such as mustard oil, wintergreen oil, Quisqualis indica, Daphne genkwa, Pharbitis nil, Zingiber officinale, Xanthium strumarium, and Camellia sinensis on earthworm, mustard oil, wintergreen oil and tea saponin were highly toxic to earthworm, Eisenia andrei. In the pot experiment, 100% of Eisenia andrei was dead at the treatment of 500-fold of aquatic solution of tea saponin (12.4% a.i.).

Precambrian metamorphic rocks of the Gapyeong-Cheongpyeong area consist of banded gneiss, augen gneiss, leucocratic gneiss, quartz schist and quartzite, together with minor intercalations of serpentinite, amphibolite and marble. Mineral assemblages of meta-sedimentary rocks are classified into three types: sillimanite-free; sillimanite-bearing; and sillimanite+K-feldspar-bearing assemblages. Compositions of metamorphic phases depend on the type of mineral assemblages. In particular, the Ca contents of plagioclase and garnet are high in sillimanite-free assemblges. Kyanite occurs in three samples, and coexists with sillimanite in one sample. The presence of kyanite indicates that metamorphic rocks of the study area have experienced the Barrovian type metamorphism. Peak metamorphic conditions estimated from various geothermobarometers and phase equilibria are 618-674$^{\circ}C$ and 6.5${\pm}$2.0 kbar for sillimanite-free assemblages, and 701-740$^{\circ}C$ and 4.4${\pm}$0.8 kbar for sillimanite-bearing assemblages, respectively. Furthermore, a clockwise P-T-time path is deduced for the study area, based on the following observations: (1) the polymorphic transition of kyanite to sillimanite, (2) the occurrence of sillimanite and K-feldspar belonging to the upper amphibolite facies, and finally (3) the retrograde metamorphism characterized by muscovite-, chlorite-, and actinolite-bearing assemblages.

This study was conducted on October 23, 2020 at the Cheongpyeong Reservoir located in Seorakmyeon, Gapyeong-gun, Gyeonggi-do, and analyzed the horizontal and vertical distribution patterns of fish based on data obtained using fishfinder. The total surface area of fishfinder survey conducted was 782,853 m², and where the water depth (WD) ranges from 10 m to 12 m is widest which 31.7% of total surface area. As a result of the heat map analysis, fish density was highest at right bank under the Gapyeong-bridge, but there was no specific pattern in horizontal distribution of fish. As a result of vertical distribution of fish analysis, 86.6% of fishes are observed at below 6 m of the fish depth (FD, distance from water surface to fish). As a result of the relative height (RH, water depth-distance from bottom to fish ratio) analysis, there was a tendency that fishes are distributed in near surface area more as the WD increased. This tendency could have various reasons such as water temperature gradient along the water depth, and further studies are required for detailed explanation.

Urbanization is a major driver of global amphibian declines. For the study on the effect of urbanization on amphibians, we compared the growth and the health status of Hyla japonica amphibians collected in the urban areas of Incheon and in the rural area of Gapyeong, Korea. The size and weight of Hyla japonica body in the urban area were smaller than those in the rural area. However, there was no significant difference in their condition factors as a health indicator between the two areas. Our study emphasizes the need for research into the specific mechanism of effects of urbanization on amphibian heath status for the further understanding of the relationship between urbanization and amphibians.

This study was conducted to estimate the habitat suitability of 17 benthic macroinvertebrate taxa in the Hwayang stream. Habitat Suitability Index (HSI) of benthic macroinvertebrates from the Hwayang stream was developed based on three physical habitat factors which include current velocity, water depth, and the substrate. The Weibull model was used as a probability density function to analyze the distribution of individual abundance by physical factors. The number of species and the total individual abundance increased along with the increase in current velocity. By means of Canonical Correspondence Analysis (CCA), the relative importance of each factor was determined in the following order: current velocity, water depth, and the mean diameter. The results depicted that, the most influential factor in the growth of benthic macroinvertebrates in the Hwavang system was current velocity. After comparing the analyzed results from the Hwayang stream with the resukts from the Gapyeong stream, the integrated HSI was drawn. The results indicated that current velocity and substrate had similar distributions of HSI in the two streams. This was due to the addition of unmeasured data from previous surveys, or the fact that benthic macroinvertebrates adapted to deeper waters in the Hwayang Stream. Most taxa showed a clear preference for a fast current velocity, deep water depth and coarse substrate except Baetiella, Epeorus, (mayflies), and Hydropsyche (caddisfly).

This study was conducted to develop an environmental index for assessing the vulnerability of areas with invasive alien plants. To that end, "Regional Vulnerability Numerical Index" (RVNI) was developed with a spatial statistical technique and applied to Seoul and Gyeonggi-do area first. The results are as follows. First, RVNI was high in stream areas. Second, RVNI was lowest in mountain areas. It indicates that stream areas are vulnerable to invasive alien plants. In terms of regions, Guri City is most vulnerable and Gapyeong-gun is the least vulnerable. To expand and manage the invasive alien plants, a control protocol should be developed by considering the physiology and ecology by invasive alien plant. Also, related policies should be pursued based on the results. Thus, the findings of this study can be used as baseline data for setting policies for invasive alien species management.
