There is no special law of Landscape architecture in Korea. So, examining the concept from the legal basis of LA with the viewpoint of a natural scientist not a jurist, this study was conducted to grasp the present condition of the name and the related text of the foreign laws in force which were connected with LA.. And those foreign laws were arranged in the name and the text and classified by nations of regional groups and it was considered to the mutual relation with lots of laws which are scattered with the various laws. Current domestic regulations to the various fields of LA are assembled with the many related rules. The governmental organization conducting those business is nonexistent up to now and it is generally known to except the dept. of LA from the office organization in Korea. Being at a disadvantage as mentioned above, this study was progressed under the necessity of the scientific basis for the expected organic law of LA proposed to establish it by every field of LA. Though feels inconvenience if the study for the items itself of LA had been proceeded prior to the study of laws relating to LA throughout the study, such a extensive study will be a subject to be attempted constantly hereafter by all part of landscape architects. The contents of the study are as follows ; 1. The present condition of the foreign laws connected with LA 1. The proposal & analysis of the problems and the solutions to the domestic laws connected with LA 3. The proposal of the reasonable application pklan in order to establish the organic law for LA. Among the items relating to LA such as engineer, contract, planning, design and supervision, construction, maintenance, plant and planting, open space, facilities, aesthetics and sight, park, land use and development planning, urban and regional planning, leisure space planning, environmental conservation and ecology, structural engineering of construction, administration, right and penal regulations, the laws dealing with the matter relating to LA directly or indirectly are prescribed dispersedly in the many other related laws and it is concluded to be impossible for the independent law of LA is likely to be establish with not only selecting and arranging the matter having closed connections to LA directly but also being recognized as the systematic equipment of the LA business. It was to be analyzed the present condition of the collected foreign laws relating to LA. After pointing out the problems to the domestic related laws being at issue, the remedies for it were presented through the questionnaire of the landscape specialist in which the supporting opinions to the recognition to the problems and the solutions were come to a major portion. Three types of application such as applicable, non-applicable, applicable after examination were presented to decide whether or not the foreign related laws were applied to the domestic one. The result of analysis shows that 42 statutes and 9 ordinances are applicable, 4 statutes and 7 ordinances are non-applicable, 1 constitution, 81 statutes and 48 ordinances are applicable after examination.

본 연구에서는 내건성 식물 선발을 위한 최적 인자를 구명하고, 이들 내건성 식물들의 생장특성을 조사하였다. 건조저항인자에 대한 나머지 건조저항일(RD), 엽면적(LD), 단위증산량(UTR), 상대함수량(RWC), 상대수분손실량(RWL), 엽면적(LA), 기공수(SN) 및 기공면적(SA) 등 6개 인자들을 비교한 결과 상대수분손실량과 단위증산량이 건조저항일에 많은 영향을 주는 것으로 나타났다. PCA분석 결과 SA, LA, RD는 한그룹으로 RWC와 SN은 다른 한 그룹으로 구분되었고, UTR은 SA, LA와, RWL은 RWC와 SN과 음의 상관을 보였다. 상기 결과를 종합하여 느릅나무, 도깨비바늘, 뚝갈, 매듭풀, 새, 더위지기, 맑은대쑥, 독말풀, 긴담배풀, 소리쟁이, 비수리, 장구채, 개기장, 도깨비가지를 내건성 식물 종으로 선발하였고, 이들에 대한 생장시험을 수행하였다. 절토사면지에서 내건성 식물의 줄기생장은 식물 종간에 약간의 차이를 보였는데, 줄기생장과 잎의 수는 느릅나무를 제외하고 폿트에서는 차이를 보이지 않았다. 그러나 절토사면지에서 내건성 식물 뿌리 생장과 T/R율은 폿트생장과 큰 차이를 보였고, 특히 T/R율은 폿트묘보다 월등히 낮았다. 이 결과로 보아 선발된 내건성 식물은 절토사면지와 같이 척박한 토양에서도 잘 적응할 것으로 나타나 내건성 식물의 육종 등에 이용될 수 있을 것으로 판단된다.

With rapid land development, land category should be updated on a regular basis. However, manual field surveys have certain limitations. In this study, attempts were made to extract a feature vector considering spectral signature by parcel, PIMP (Percent Imperviousness), texture, and VIs (Vegetation Indices) based on RapidEye satellite image and cadastral map. A total of nine land categories in which feature vectors were significantly extracted from the images were selected and classified using SVM (Support Vector Machine). According to accuracy assessment, by comparing the cadastral map and classification result, the overall accuracy was 0.74. In the paddy-field category, in particular, PO acc. (producer's accuracy) and US acc. (user's accuracy) were highest at 0.85 and 0.86, respectively.

Objective: In dryland areas of China, alfalfa hay (AH) is a possible substitute for concentrate feed for beef cattle. To evaluate the potential benefits of this substitution, we studied the effect of the ratio of AH intake to total dry matter (DM) intake on average daily body-weight gain (ADG), dietary energy utilization status, and economic benefit in Gansu province. Methods: In each of two feeding trials in 2016 (trial 1 [T1], July 3 to 17; trial 2 [T2], August 15 to September 23), crossbred male Simmental calves were allocated to low AH (LA), medium AH (MA), and high AH (HA) feeding groups (n = 4 per group). The target ADG was set as 1 kg for both trials. In a one-way-layout design based on conventional feeding practices in the province, calves received diets containing the different AH amounts, with a constant ratio of corn stover:total DM and decreasing rations of concentrate feed proportional to the increase in AH. Calves in T1 received AH at 15% (T1-LA), 23% (T1-MA), or 31% (T1-HA) of their dietary DM allowances; those in T2 received 9% (T2-LA), 24% (T2-MA), or 34% (T2-HA) AH. Results: Among the T1 groups, both ADG and economic benefit were highest in T1-LA; whereas in T2, they were higher in the T2-LA and T2-MA groups than in T2-HA. Energy digestibility did not significantly differ among the groups in either trial. The dietary AH inclusion ratios of 14% in the warm season and 8% to 21% in the cool season appeared to yield optimal ADG, metabolizable energy intake, and economic benefit. Conclusion: Low-level inclusion of AH, ranging from 8% to 21%, is a practical approach for beef cattle feeding. This modified feeding regimen likely will promote increased growth performance during the fattening stage of beef steers in dryland areas of Gansu province, China.

It is important to consider the effects of land-use changes on surface runoff, stream flow, and groundwater recharge. Expansion of urban areas significantly impacts the environment in terms of ground water recharge, water pollution, and storm water drainage. Increase of impervious area due to urbanization leads to an increase in surface runoff volume, contributes to downstream flooding and a net loss in groundwater recharge. Assessment of the hydrologic impacts or urban land-use change traditionally includes models that evaluate how land use change alters peak runoff rates, and these results are then used in the design of drainage systems. Such methods however do not address the long-term hydrologic impacts of urban land use change and often do not consider how pollutants that wash off from different land uses affect water quality. L-THIA (Long-Term Hydrologic Impact Assessment) is an analysis tool that provides site-specific estimates of changes in runoff, recharge and non point source pollution resulting from past or proposed land-use changes. It gives long-term average annual runoff for a land use configuration, based on climate data for that area. In this study, the environmental and hydrological impact from the urbanized basin had been examined with GIS L-THIA in Korea.

Pb-contaminated soil at a clay shooting range was analyzed by the sequential extraction method to identify metal binding properties in terms of detrital and non-detrital forms of the soil. Most of the metals in the soils existed as non-detrital forms, exchangeable and carbonate-bound forms, which could be easily released from the soil by a washing method. Therefore, the characteristics of Pb desorption for remediation of the Pb-contaminated soil were evaluated using hydrochloric acid (HCl) by a washing method. Batch experiments were performed to identify the factors influencing extraction efficiency. The effects of the solid to liquid (S/L) ratio (1:2, 1:3, and 1:4), soil particle size, and extraction time on the removal capacity of Pb by HCl were evaluated. Soil samples were collected from two different areas: a slope area (SA) and a land area (LA) at the field. As results, the optimal conditions at 2.8 to 0.075 mm of particle size were 1:3 of the S/L ratio and 10 min of extraction time for SA, and 1:4 of the S/L ratio and 5 min of extraction time for LA. The characteristics of Pb desorption were adequately described by two-reaction kinetic models.

Urban sanitary sewer systems can aid in preventing inundation, and can improve civil health by effectively disposing stormwater and wastewater. However, since sewage odor can cause adverse effects, numerous technical and administrative studies have been conducted for reducing such odor. European countries and the United States of America (USA) built modern sewer systems in the late 19th century, and have since been endeavoring to eliminate sewage odors. Several cities of the USA, such as Los Angeles (LA) that has a separate sewer system and San Francisco (SF) that has a combined sewer system, have produced and distributed odor control master plan manuals. Features common in the odor reduction plans of both these cities are that the odor reduction programs are operated in all the respective local regions and are supported by administrative systems. The primary aspectual difference between the two said programs is that the city of LA employs a sewage air purification system, whereas the city of SF controls the emission of major odor causing compounds. Compared to the existing sewer odor reduction systems of these two cities, South Korea is still in the initial phase of development. Through technical studies and policy implementations for sewer odor reduction, a foundation can be laid for improving the civil health quality.

최근 내분비장애 추정물질의 분류를 위해 많은 시험법이 연구되고 있으며 미국 EPA와 OECD에서는 시험법을 설정하려고 노력하고 있다. 추후 기등록농약에 대한 자료요구 또는 신규 등록농약 적용 등록기준의 추가 등을 고려하여 내분비계장애 추정물질 관련 OECD와 EPA에서 권장하는 시험법을 확립하고자 본 연구를 수행하였다. 시험약제를 30일간 경구 투여하여 조사한 결과, metribuzin 투여 수컷에서 부고환, 전립선, 정낭의 중량이 증가하였고 갑상선에서는 유의한 중량변화가 나타나지 않았다. 암컷에서는 갑상선의 중량 감소가 나타난 반면에 생식장기 중량에는 유의적인 변화가 없었다. Metribuzin 투여수컷에서 testosterone이 100 mg/kg/day 처리수준에서 감소하였고 FT4가 50, 100 mg/kg 수준에서 증가하였다. 암컷에서는 T3가 50, 100 mg/kg/day 수준에서 증가하여 갑상선 호르몬에 영향이 나타나는 것을 볼 수 있었다. 시험세포를 이용한 시험결과, 시험약제를 1 nM에서 1,000 nM까지 처리하였을 때 음성대조군과 비교할 때 metribuzin은 106-122%의 영향을 나타내어 세포이용시험에서는 metribuzin이 갑상선 호르몬성 영향을 보인 것으로 나타났다. 항갑상선 호르몬성 영향 시험에서는 시험약제 100 nM과 T4의 혼합 처리시 metribuzin은 양성 대조군과 비교하여 감소하여 항갑상선 호르몬성 영향을 나타내었다. 본 시험을 통하여 OECD TG 407과 EDSTAC에서 권고하는 pubertal assay와 수의과학 검역원에서 제조한 HeLaTRE cell을 이용한 in vitro 시험이 갑상선 호르몬성 영향 검색 시험으로 활용될 가능성이 있는 것으로 사료되었다.
