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㎡.

악골낭종의 임상 방사선학적 연구

박태원,Park Tae Won 대한영상치의학회 1983 Imaging Science in Dentistry Vol.13 No.1

The author analyzed 243 cases clinically and radiographically which were diagnosed as odontogenic cyst in SNUH during 10 years (1974. 1 - 1983. 12). The obtained results were as follows: 1. This cyst occurred more frequently in male than in female and the incidence was the highest in the 3rd decade. 2. Maxilla was more frequently affected than mandible 3. Most of the odontogenic cysts were unilocular type (236 cases, 97.1%), showing distinct border (242 cases, 99.6%) with smooth margin (222 cases, 91.7%). 4. The adjacent teeth showed root resorption in 57 cases (23.5%), and root divergence in 52 cases (21.4%). 5. The cyst in lower jaw caused the displacement of the mandibular canal wall in 30 cases (31.25) 4. and root divergence in 52 5. 6. The cyst in upper jaw extended to the maxillary sinus in 61 cases (41.5%)

Cu를 함유한 저합금 고장력강의 미세 조직에 미치는 열처리의 영향

A study was made to examine the effects of heat-treatment on the microstructures of Cu-bearing HSLA steels. The details of microstructures were studied by using optical microscopy(OM), transmission electron microscopy(TEM) and hardness test. The as-rolled microstructure of HSLA-A consists of ferrite(α) whereas that of HSLA-B consists of needle-shaped phase. The difference in microstructure can be ascribed to the different amount of Ni, Mn, Mo, Cu which affect the hardenability. The sustenite grain size is very small up to 1000℃ owing to the Nb-precipitates. As the austenitizing temperature increases above 1000℃, the austenite grain grows rapidly. There are two hardness peaks in the hardness versus temperature curve, at 500℃ and at 675℃(HSLA-A), 725℃(HSLA-B). The peak at 500℃ result from the formation of Cu-precipitates and second hardness peak is created due to the formation of M-A constituents. The hardness decrease in HSLA-B steel with ageing temperature is small because of the higher amounts of Cu than HSLA-A steel. The fine, round ε-Cu precipitates grow with ageing temperature and finally transform into rod shape.

Cu를 함유한 HSLA-100강 용접 열영향부의 미세 조직 및 인성

A study was made to characterize the microstructures and mechanical properties of the base metal and the heat-affected zone(HAZ) in Cu-bearing HSLA-100 steel. The Gleeble thermal/mechanical simulator was used to simulated the weld HAZ. The relationship between microstructure and toughness of HAZ was studied by impact test, O.M, SEM, TEM, and DSC. The toughness requirement of military specification value was met in a.ll test temperatures for the base metal. The decrease of HAZ toughness comparing to base plate is ascribed to the coarsed-grain and the formation of bainite. Obliquely sectioned Charily specimens show that secondary crack propagate easily along bainite lath. Improved toughness(240J) at HAZ of Tp₂=950℃ is due to the fine grain, and reasonable toughness(160∼200J) in the intercritical reheated HZA is achieved by the addition of small amount of carbon which affects the formation of M-A. Cu precipitated during ageing for increasing the strength of base metal is dissolved during single thermal cycle to 1,350℃ and is precipitated little on cooling and heating during subsequent weld thermal cycle. Thus, the decrease of toughness does not occur owing to the precipitation of Cu.

The authors analyzed the clinical findings, radiological findings and their correlations in the temporomandibular joint disorders. The results were as follows: 1. The most prevalent age group was in the first decade, then the second decade and the third decade. Female were more common with a ratio of 3.4:1. 2. The most common clinical findings was the pain on open mouth position (42.3%), then came the clicking and limitation of mouth opening. 3. The most common bone change on the condyle side was the erosion, then came the flattening, the osteopyte and the sclerosis in that orders. 4. In the case of the crepitus, the coarse crepitus showed more radiological change than the fine crepitus. The 27% of the patients with crepitus showed the bone change and the patients with crepitus showed more bone change than any other clinical symptoms. 5. In the case of the mouth opening limitation, the evaluation of the translatory movement by transcranial projection was in accordance with the clinical evaluation. 6. The correlation between the clinical symptom and the condylar position within the mandibular fossa was not present and in the case of diagnosis of disc displacement, the transcranial projection seemed not to be able to substitute for the arthrography. Radiographically, the most prevalent age group which showed the bone change was in the first, the second and the third decade. And the bone change seemed to have no relationship with aging.

A study was conducted to examine the effects of In addition on the precipitation behaviors of Al-2.1Li-2.9Cu alloy by differential scanning calorimetry, transmission electron microscopy and microhardness tester. DSC analysis was measured over the temperature range of 25∼50℃ at a heating rate of 2∼20℃/min. The heat evolution peaks due to the formation of GP zone and δ` phase shift to higher temperature and the peaks to T₁and θ` phases shift to lower temperature by In addition. From this result, it was proved that the formation of GP zone and δ` phase is suppresed whereas that of T₁and θ` phases are accelerated by the In addition of 0.15wt%. The age hardening curve aged at 190℃ showed that the In bearing alloy(alloy B) has more faster age hardening response and a higher peak hardness than In-free alloy(alloy A), attributed to the fine and homogeneous distribution of T₁and θ` phases. The activation energies for the formation of δ`phase in In-free and In-bearing alloys are 22.3㎉/㏖ and 18.6㎉/㏖, respectively. Those for T₁(+θ`) phase of In-free and In-bearing alloys are 24.3 and 37.5㎉/㏖, respectively. Quenched-in excess vacancies play an important role to the formation of precipitates.

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.
