Since the Constitutional Court ruled in July 1999 that the private urban planning facilities were subject to the violation of private property rights, the government has adopted a sunset system for urban parks. While the private business owner s size of urban parks was lowered from 80 % to 70 % in 2014, the cause of the controversy over the project was changed from 100,000㎡ or more in total urban parks to 50,000㎡ or more. Therefore, this study analyzes the causes of failure in the public park formation projects based on the cases in which conflicts are emerging in analyzing similar systems abroad and promoting projects, and analyzes the causes of failure through related experts and surveys. In addition, the causes of conflicts are different, local sentiments and development conditions are different, and the limit of urban park management and response plans for future urban urban planning based on projects focused on the business feasibility and retrofittibility are limited, and urban park plans are less than 50,000㎡.

변형강도 시험용 하중봉의 원형절삭반경 선정연구

박태원,도영수,김광우,Park, Tae-W.,Doh, Young-S.,Kim, Kwang-W. 한국도로학회 2008 한국도로학회논문집 Vol.10 No.2

본 연구에서는 아스팔트 혼합물의 변형강도시험에서 하중봉의 치수가 변형강도 특성에 미치는 영향을 평가하였다. 이를 위하여 직경(D) 40mm, 하단의 원형 절삭 반경(r)을 10.0mm와 10.5mm로 제작한 두 개의 하중봉으로 아스팔트 혼합물의 변형강도를 측정하고, 반복주행시험을 수행하여 얻어진 소성변형 특성치와 상관성 분석을 하였다. 또한 하중봉의 원형 절삭반경에 따른 골재치수에 어떠한 영향을 미치는지를 확인하기 위하여 통계 분석을 하였다. 변형강도 값과 변동계수는 r=10mm하중봉을 사용한 것이 더 낮은 것으로 나타났다. 또한 r=10mm 하중봉이 변형강도와 소성변형 특성치와 상관성 분석에서도 더 높은 상관성을 보였다. 골재치수와 원형 절삭반경은 변형강도에 영향을 미치는 것으로 나타났으나 두 변수의 교호작용에서는 골재의 크기가 $10mm{\sim}19mm$내에서는 r에 영향을 받지 않는 것으로 나타났다. 따라서 소성변형과의 상관성이 더 우수하며 변동계수도 낮은 것으로 나타난 D=40mm, r=10.0mm의 하중봉을 사용하는 것이 적합할 것으로 판단되었다. This study evaluated influence of the loading head dimension on characteristics of deformation strength ($S_D$) of asphalt mixtures. Kim test and Wheel tracking (WT) test were conducted to evaluate $S_D$ characteristics with relation to WT results for various mixtures. The $S_D$ values and coefficient of variation of $S_D$ values of r=10mm were smaller than those of r=10.5mm. It was also found that $S_D$ values obtained using r=10mm loading head showed high correlations with rut parameters of WT test. It was indicated that the aggregate size and radius (r) of round cut were statistically significant variables on $S_D$ at = 0.05 level in the analysis of variance. However, in interaction of r and aggregate size showed no significance within $10{\sim}19mm$ aggregate size at the same level. Therefore, it was concluded that the diameter (D) of 40mm and the bottom edge radius (r) of 10mm was suitable dimension of loading head for deformation strength test.

Cu를 함유한 저합금 고장력강의 기계적 성질에 미치는 열처리의 영향

박태원,심인옥,김영우,강정윤,Park, Tae-Won,Sim, In-Ok,Kim, Yeong-U,Gang, Jeong-Yun 한국재료학회 1995 한국재료학회지 Vol.5 No.3

Cu를 함유한 2종의 저합금 고장력강(HSLA-A, HSLA-B)\ulcorner 기계적 성질에 미치는 시효처리의 영향을 조사하였다. 탄소량이 적음에도 불구하고 Cu첨가로 석출물을 생성시킴으로서 2합금 모두 $650^{\circ}C$에서 시효한 경우 양호한 강도(HSLA-A:Y.S 703Mpa, E.L 22.6% HSLA-B:Y.S 810 Mpa, E.L 23.8%)와 인성(HSLA-A:271.4J, HSLA-B:197.5J at -5$0^{\circ}C$)의 조합을 나타내었다. 50$0^{\circ}C$에서 시효할 때 가장 높은 항복 강도를 나타내나 인성은 아주 낮은 값을 나타내었다. 50$0^{\circ}C$이상 시효 온도가 증가하면 강도는 감소하고 인성은 증가하였다. HSLA-B강의 강도가 HSLA-A 강보다 높은데, \ulcorner칭 상태에서의 강도 차이는 경화능을 증가시키는 원소인 Ni, Mn, Mo, Cu의 첨가량 차이에 의한 기지 조직의 차이에 의한 것이며, 시효한 상태에서의 강도 차이는 기지 조직과 석출 강화에 기여하는 Cu량의 차이에 의한 것으로 판단된다. 시효 경화 곡선에서 $700^{\circ}C$에서의 경도 증가는 오스테나이트-페라이트 2상 영역으로부터 냉각시 생성된 “M-A constituents”에 의한 것이다. HSLA-A강과 HSLA-B강의 충격 천이 온도는 각각 -1$25^{\circ}C$와 -145$^{\circ}C$이었다.

다발성 낭종의 증예보고

박태원,이상래,Park Tae Won,Lee Sang Rae 대한영상치의학회 1973 Imaging Science in Dentistry Vol.3 No.1

The authors have interpreted one patient's full mJuth intra-oral films, oblique- lateral film of the left mandible and orthopantomograph which revealed 6 radicular and 1 residual cysts. As a results of interpretation of these serial films, we have drawn following conclusions: 1. Radicular cyst arose from the cell rests contained in an apical granuloma which was sequel to advanced pulpitis due to dental caries. 2. Residual cyst was developed from remaining cell rests after the extraction of a tooth with such a radicular cyst or apical dental granuloma. 3. Cyst grew in size by absorption of fluid into cystic cavity due to difference in osmotic pressure between the cystic fluid and adjacent tissue fluid.

한국인 주의력결핍 과잉행동장애와 세로토닌 1B 수용체 유전자 다형성의 관련성:가족기반 연구 및 환자-대조군 연구

Objective:Attention deficit hyperactivity disorder(ADHD) is the most common childhood psychiatric disorder, affecting 3-5% of school-aged children. Although the biological basis of ADHD is unknown, family studies provide strong evidence that ADHD has a genetic basis. Recent genetic studies have suggested associations between ADHD and serotonin 1B(5HT1B) receptor gene G861C polymorphism. The aim of this study is to test for the association between ADHD and 5HT1B receptor gene G861C polymorphism in Korean population. Method:We processed DNA extraction and genotyping. 106 Korean children with ADHD and their parents were analyzed using the transmission disequilibrium test(TDT) and haplotype-based haplotype relative risk (HHRR). And the ADHD children were compared with 212 age and gender matched normal controls. Results:There was no statistical difference of distributions between ADHD cases and controls. We did not observe any preferential transmission of alleles of 5HT1B receptor gene G861C polymorphism in ADHD. Conclusions:Though there is the possibility of failing to detect small genetic effects, our results show no evidence of an association between ADHD and 5HT1B receptor gene G861C polymorphism in the Korean population and indicate that it is unlikely that the 5HT1B receptor is implicated in the susceptibility to ADHD.

ALKANE의 微生物酸化의 反應條件과 炭素 및 窒素平衡

박태원,Park Tai Won 대한화학회 1969 대한화학회지 Vol.13 No.2

As part of an extensive program on the microbiological oxidation of hydrocarbons, reaction conditions and nutrients consumption of candida lipolytica grown on alkane as carbon source were studied. For optimum growth of yeast, the conditions of pH 5, temperature $30^{\circ}C$, carbon number $C_{16}$& $C_{18}$aeration 25.6 1/l/hr, agitation 3000 r.p.m., hydrocarbon concentration 10% were obtained. Carbon and nitrogen balance related to these conditions were also investigated. In the course of this investigation, some significant effects of pH and carbon number of hydrocarbon variation were observed.

박태원,서형준,Park Tai Won,Suh Hyung Joon 대한화학회 1977 대한화학회지 Vol.21 No.6

脂質 生産의 새로운 供給源으로 고려될 수 있는 石油炭化水素 醱酵에 의한 菌體脂質의 生成에 있어서 炭化水素의 炭素數의 影響과 그 脂肪酸의 組成을 檢討하였다. 菌株로서 Rhodotorula sp., 基質로서 炭素數가 짝수인 n-tetradecane과 n-hexadecane을 使用하여 容量 2l의 醱酵槽에서 溫度 $28^{\circ}C$, pH 4.0 ∼ 4.6, 酸素供給速度 0.4vvm, 攪拌速度 1000 rpm의 條件에서 醱酵시켜 生成된 菌體를 回收, 乾燥後 菌體脂質을 抽出하고 gas-liquid chromatography로 醱酵酸 組成을 檢索한 바, n-tetradecane과 n-hexadecane을 基質로 한 경우, 生成菌體의 脂質含量은 各各 12.0 및 25,8 %이었으며 菌體 脂肪酸은 大部分 炭素數가 짝수인 脂肪酸으로 構成되어 있었다. The effect of carbon number of hydrocarbon used as a carbon source in the production of cellular lipid of Rhodotorula sp. and its fatty acid composition were investigated. Using Rhodotorula sp. on n-tetradecane and n-hexadecane whose carbon numbers are even, fermentation was carried out in a jar fermentor of 2 liter-capacity at $28^{\circ}C$, with pH range of 4.0∼4.6 and at oxygen flowing rate of 0. 4 vvm and agitation velocity of 1000 rpm. Drying the produced cell after completion of fermentation, cellular lipid was extracted from the cell using soxhlet extractor and examined its fatty acid composition by gas-liquid chromatography. Cellular lipid content in the cell produced on n-tetradecane and n-hexadecane were 12.0 % and 25,8 % on the basis of dry cell weight, respectively and their fatty acids were mostly even numbered in carbon number.
