도시의 급격한 팽창과 함께 주택부족 현상이 나타나게 되자, 정부는 주택부족 문제 해결을 위해 대규모 택지개발을 통하여 주택보급을 확대시켰다. 이러한 현상으로, 공동주택은 우리나라 전체 주택의 83% 수준을 유지하고 있고, 그 중 아파트가 차지하는 비중은 50%로 꾸준한 증가 추세를 보이고 있다. 이로 인해 아파트의 경우 입주민들의 승용차 보유 증가에 따른 아파트 단지 내 주차공간 부족문제 등 제반 주차 관련 문제가 발생하고 있다. 특히, 주차계획대수 수립 시 교통영향평가의 주차수요예측 중 전용면적을 고려한 주차원단위 산정 방법은 기존 계획보다 세대수는 증가하여도 전용면적이 작아지면 계획주차대수는 감소하는 것으로 나타나, 보다 현실적인 주차원단위 산정이 필요한 실정이다. 이에 본 연구는 공공주택 아파트를 대상으로 현실에 적합한 주차원단위를 산정하고자 한다. 현장조사 및 설문조사를 실시하고, 구득자료에 대한 분석을 수행함으로써, 기존 교통영향평가의 주차원단위 산정 문제점을 도출하였다. 또한, 주차수요예측에 영향을 미치는 요인 선정을 통해 주차원단위 산정모형을 개발하였다. 마지막으로 실제 조사된 아파트 주차원단위 자료를 통해 기존 교통영향평가의 주차원단위 산정과 본 연구에서 제시한 주차원단위 산정모형을 비교 분석하였다. 향후 본 연구에서 개발된 주차원단위 산정모형은 주차장법 기준 정립은 물론 보다 현실적인 주차수요예측 수행에 적극 활용될 수 있을 것으로 판단된다. The rapid expansion of cities led to the shortage of housing in urban areas. The government compensated for this shortage through large scale residential developments that increased the housing supply. The supply of condominium apartments remains above 83% of the entire housing supply, and the proportion of apartments are at a steady increase, at about 50%. Due to the increase, illegally parked cars resulting from the shortage of parking spaces within the apartment complex have become increasingly problematic as they block the transit of emergency vehicles, and heighten the tension among neighboring residents in obtaining a parking space. Especially, the future residents are considered to plan the parking based on the estimated demand for parking. However, the parking unit method utilized to estimate the parking demand accounts for the exclusive use of space, which is believed to be far from the parking demands in reality. The reason for this discrepancy is that, as the number of households decrease, and area of exclusive space is expanded, the planned parking increases. On the other hand, when the number of households increase, and the area of exclusive space is reduced, the planned parking decreases, thus methods to recalculate the parking units based on estimated parking demand is an urgent concern. To estimate the parking units based on condominium apartments, this study first examined the existing research literature, and appointed the field of investigation to collect the necessary data. In addition, field study data and surveys collected and analyzed, in order to identify the problems underlying parking units, and problems regarding the current traffic impact assessment parking unit calculation method were deduced. Through identifying the influential factors on parking demand estimates, and performing a factorial analysis based on the collected data, the variables were selected in relation to the parking demand estimates, to develop the parking unit estimate model. Finally, through comparing and verifying the existing traffic impact assessment parking unit estimate against the newly developed model using collected data, a far more realistic parking unite estimate was suggested, reflecting the characteristics of the residents. The parking unit estimate model developed in this study is anticipated to serve as the guidelines for future parking lot legislature, as wel as the basis to provide a more realistic estimate of parking demands based on the resident characteristics of an apartment complex.

The purpose of this study is to quantitatively evaluate the amount of carbon storage for trees in forest ecosystem to support the foundation for carbon neutrality implementation in Korea National Park. It targeted 22 national parks designated and managed as national parks in Korea, and conducted research on forest trees in the terrestrial ecosystem among various natural and ecological carbon sink. The survey and analysis method followed the IPCC guidelines and the National Greenhouse Gas Inventory in Korea. The amount of tree carbon storage in the forest ecosystem of Korea National Park was confirmed to be about 218,505 thousand CO₂-ton and the amount of carbon storage per unit area was 570.8 CO₂-ton per hectare. Compared to 299.7 CO₂-ton per hectare, the average carbon storage per unit area of the entire Korean forest, it was found that about twice as much carbon was stored when assuming the same area. In other words, it means that the tree carbon storage function of the national park is about twice as high as that of the average tree carbon storage function of entire Korean forest. It has great implications in Korea National Park not only provides biodiversity promotion and exploration services as a national protected area, but also performs excellent functions as a carbon sink.

Background p19arf, primarily known as a tumor suppressor, has also been reported to play an essential role in normal development of mouse eyes. Consistently, lack of p19arf has been associated with ocular defects, but the mixed background of the knockout (KO) mouse strain used raised a concern on the accuracy of the phenotypes observed in association with the targeted gene due to genetic heterogeneity. Object We carried out a study to investigate into the efect of genetic background on the manifestation of p19arf KO associated phenotypes. Methods We characterized the phenotypes of novel p19arf KO mouse lines generated in FVB/N and C57BL/6J using a transcription activator-like efector nuclease (TALEN) system in comparison to the reported phenotypes of three other p19arf-defcient mouse lines generated using homologous recombination. Results Ninety-fve percent of FVB/N-p19arf KO mice showed ocular opacity from week 4 after birth which worsened rapidly until week 6, while such abnormality was absent in C57BL/6J-p19arf KO mice up to the age of 26 weeks. Histopathological analysis revealed retrolental masses and dysplasia in the retinal layer in FVB/N-p19arf KO mice from week 4. Besides these, both strains developed normally from birth to week 26 without increased tumorigenesis except for a subcutaneous tumor found in a C57BL/6J-p19arf KO mouse. Conclusion Our fndings demonstrated surprisingly variable manifestation of p19arf-linked phenotypes between FVB/N and C57BL/6J mice, and furthermore between our mouse lines and the established lines, indicating a critical impact of genetic background on functional study of genes using gene targeting strategies in mice.

The purpose of this study is to observe and compare the remineralization tendencies of artificial enamel caries lesion by remineralization solutions of different degree of saturations at pH 5.5, using a polarizing microscope and computer programs (Photoshop, Image pro plus, Scion Image, Excel). For this study, 48 sound permanent teeth with no signs of demineralization, cracks, or dental restorations were used. The specimens were immersed in lactic acid demineralization solution for 2 days in order to produce artificial dental caries that consist of surface and subsurface lesions. Each of 9 or 10 specimens was immersed in pH 5.5 lactic acid buffering remineralization solution of four different degrees of saturation (0.507, 0.394, 0.301, and 0.251) for 12 days. After the demineralization and remineralization, images were taken by a polarizing microscope (×100). The results were obtained by observing images of the specimens, and using computer programs, the density of caries lesions were estimated. While the group with the lowest degree of saturation (0.251) showed total remineralization feature from the surface to the subsurface of the lesion, the group with the highest degree of saturation (0.507) showed demineralization mainly on the surface of the lesion at the constant organic acid concentration 0.01 M and pH 5.5. 본 연구에서는 lactic acid를 이용하여 인공 탈회용액을 제조하여 우식이 없는 치아로 시편을 만들고 법랑질 부위에 인공 우식 병소를 생성 시키고 유기산 농도 0.01 M, pH 5.5로 고정한 상태에서 유기산 완충용액의 포화도를 달리하여(0.507, 0.394, 0.301, 0.251) 재광화를 시키고 편광 현미경하에서 관찰 및 디지털 카메라로 촬영하였다. 이를 통해 얻은 상에서 탈회 깊이의 변화, 우식 표면층 폭의 변화, 무기질의 양적 변화를 컴퓨터 프로그램을 이용하여 비교, 통계 분석하여 다음 결과를 얻었다. 1. 재광화 전에 비하여 재광화 후 모든 군에서 10-30% 재광화 양이 증가 하였다. 2. 재광화 후 4군에서는 우식 표면층과 심부 모두에서 재광화가 일어나는 양상이 나타난 반면 1군에서는 심부 보다 우식 표면층 부위의 재광화가 더 일어난 양상이 관찰되었다. 3. 재광화 후 시편의 탈회된 깊이의 변화는 탈회시킨 후와 비교할 때 모든 군에서 유의할만한 변화는 없었으며 군간의 통계적 유의차도 없었다. 결론적으로, 유기산 0.01 M, pH 5.5로 고정한 상태에서 포화도가 가장 낮았던 군(0.251)에서는 우식 표면층에서 심부까지 재광화가 일어난 반면, 포화도가 가장 높았던 군(0.507)에서는 우식 표면층에서 재광화가 주로 일어났다.
