The purpose of this investigation is to propose a planning method for the possibility of accepting a housing as a utilization plan of a long term unexecuted park site. Currently, the park has been neglected due to lack of financial resources of the local government. In 2009, It is possible to develop a certain area as a non-park facility under condition that the park is built and donated. In the several cities, various projects for development of parks are being carried out, so the standard for securing the publicness of the park is needed. So, I would like to solve the problems such as social conflict with existing residents due to privatization of the park site and formation of park without considering the conditions of the park, and to study how to effectively utilize the park. To do this, we examine the conditions such as location condition, proximity to public transportation, site size, topography, and contact conditions. And we will present realization methods such as land use, development density, appropriate development method considering landscape, efficient housing type, and type of community facility.

This study investigates when and why the light pink Dan-ryoung appeared as part of the official uniform of the Joseon Dynasty and which official uniform used the light pink color. The Annals of the Joseon Dynasty, books written by scholars, and related laws were used as research materials. The following results were obtained by analyzing the arguments of kings and officials on light pink uniforms and laws related to official uniforms. 1. Red was the color of the king as well as the color of Dang-sang-gwan`s Gong-bok (one of the official uniforms). 2. The colors such as To-hong, Dam-hong, Do-hong, Bun-hong, Cheon-hong that appeared in Sang-bok (among official uniforms) were relatively lighter than red. 3. To-hong started to be used in Sang-bok at the time of King Se-jong and was used at the time of King Seong-jong in Sang-bok because it was the preferred color. 4. In the Joseon Dynasty, safflower (the basis of red color dye) was cultivated extensively; in addition, people liked red dyeing because it was relatively easy apply; subsequently, a ban on red dyeing was continually issued. 5. Kings Se-jong and Jung-jong ordered officials to use Do-hong and Bun-hong to distinguish the red color of the king. After Im-jin-oe-ran, Cheon-hong was officially designated the color of Sang-bok. 6. The reasons why Dam-hong was used in official uniforms were twofold: the preference for red-like colors and the influence of the Confucian hierarchy to distinguish the king.

박현정,Park, Hyun-Jung 한국정보통신학회 2014 한국정보통신학회논문지 Vol.18 No.4

본 연구에서는 지하굴착공사에서 굴착단계별 변위형상도를 미리 예측하는 기법에 관하여 역해석 알고리즘을 이용하여 현장시공사례에 적용하고 그 타당성을 검증하고자 한다. 이를 위해 IT 분야의 정보 처리 지식이 필요하고 전공융합의 필요성이 대두되어 건설 분야에 알고리즘의 적용을 시도하고자 한다. 본 연구의 기법에서 예측변위형상도는 굴착시공 시 연속벽체에 작용하는 토압과 연관이 있으며 이는 앵커 제거 후 시공하는 연속벽체의 안정성에 영향을 미치기 때문에 굴착단계별 변위형상도를 미리 예측하는 것은 아주 중요한 문제이다. 본 연구에서는 이를 위해 3곳의 지하연속벽을 사용한 현장에 반복적 역해석 알고리즘 기법을 세 단계로 적용하여 최종굴착 시 계측변위와 비교하였다. 그 결과 계측치와의 변위형상도가 잘 일치하고 있어 본 연구의 해석기법에 대한 타당성이 있음을 알 수 있었다. In this study, we applieorithmd the inverse analysis alg to the prediction of displacement shape in the example construction and verified the feasibility of suggested algorithm. For this purpose, as information processing knowledge in the field of IT is required and the need for convergence with the major is emerged, it is intended to try to apply the algorithm to the construction sector. Prediction of displacement shape is very important since it is related to the earth pressure of slurry wall and effecting on the safety of slurry wall after anchor removal. 3 levels of inverse analysis were applied to the slurry walls in 3 sites and compared the measured displacement shape with predicted displacement shape of the last excavation construction. As the predicted displacement shape was matched well with the measured one, the applied analysis algorithm in this study can be applied to the excavation construction.

Purpose : To investigate the reproducibility of the conventional and digital radiographs to determine the depth of approximal root cavities. Materials and Methods : A total of 80 artificial root cavities were prepared in the approximal surfaces of premolars, maxillary and mandibular molars. Standardized radiographs were taken at the baseline (0° horizontal and 0° vertical) and at a horizontal angulation of 10° in both mesial and distal directions. Radiographic cavity depths were measured by both conventional and digital radiographs. Results: At 0° horizontal angulation, no statistically significant differences could be determined between the results of conventionally and digitally determined radiographic depths with respect to the actual cavity depths in all premolar, maxillary, and mandibular molar groups. All conventional and digital radiographic depths at both 10° mesial and distal angulations showed statistically significant increases in depth compared to the actual cavity depths (p < 0.05), with the exception of digital radiographic depth at 10° mesial angulation for premolars. There were no statistically significant differences between conventional and digital radiographic depths for all groups. Conclusion: The present study suggests that both conventional and digital radiographs provide reproducible assessment of the depth of the approximal root cavity. But horizontal X-ray beam movements are likely to result in increase in radiographic cavity depth.

광학 시뮬레이션을 이용한 Patterned Sapphire Substrate에 따른 Flip Chip LED의 광 추출 효율 변화에 대한 연구

박현정,이동규,곽준섭,Park, Hyun Jung,Lee, Dong Kyu,Kwak, Joon Seop 한국전기전자재료학회 2015 전기전자재료학회논문지 Vol.28 No.10

Recently many studies being carried out to increase the light efficiency of LED. The external quantum efficiency of LED, generally the light efficiency, is determined by the internal quantum efficiency and the light extraction efficiency. The internal quantum efficiency of LED was already reached to more than 90%, but the light extraction efficiency is still insufficient compared with the internal quantum efficiency because the total internal reflection is generated in the interface between the LED chip and air. Thus, we studied about flip chip LED with PSS and performed the optical simulation which find more optimized PSS for flip chip LED to increase the light extraction efficiency. Decreasing of the total internal reflection and effect of diffused reflection according to PSS improved the light extraction efficiency. To get more higher the efficiency, we simulated flip chip with PSS that the parameters are arrangement, edge spacing, radius, height and shape of PSS.

박현정,고은경,위성환,윤하정,허은정,김영조,이희수,문진산,Park, Hyun-Jung,Go, Eun-Kyung,Wee, Sung-Hwan,Yoon, Ha-Chung,Heo, Eun-Jeong,Kim, Young-Jo,Lee, Hee-Soo,Moon, Jin-San 한국축산식품학회 2012 한국축산식품학회지 Vol.32 No.1

현재 국내 일부 햄과 소시지류 제조공장에서 식중독 세균에 대한 제어방안으로서 1차 가열살균 이후 제품포장 단계에서 2차 가열살균을 추가적으로 실시하고 있다. 이에 본 연구에서는 2010년 2월부터 11월까지 국내 10개 육가공제조회사에서 햄류 53개 품목과 소시지류 37개 품목의 동일 롯트에서 1차 가열 시료와 2차 가열까지 실시한 시료를 각각 6개씩 채취하여 축산물의 가공기준 및 성분규격에 따라 Salmonella spp., S. aureus, L. monocytogenes 및 C. perfringens 식중독 세균 오염 여부를 조사하였다. 햄과 소시지류 총 1,080건에 대한 검사 결과 S. aureus는 2개 제조회사에서 생산한 햄 4개 시료에서 검출되었으며, 그 중 3건은 1차 가열제품에서 나머지 1건은 2차 가열살균까지 처리한 제품에서 검출되었다. L. monocytogenes는 5개 제조회사에서 햄류 4건, 소시지류 8건을 포함하여 총 12건이 검출되었으며, 그 중 7건은 1차 가열 처리한 제품에서, 나머지 5건은 2차 가열까지 처리한 제품에서 각각 검출되었다. C. perfringens는 3개 제조회사의 햄류 1건과 소시지류 2건에서 검출되었으며, 1차 가열만 한 제품에서 1건, 2차 가열까지 한 제품에서 2건이 각각 검출되었다. 이에 반하여 Salmonella spp.는 한 건도 검출되지 않았다. 1차 가열살균 제품과 1차와 2차 가열살균 과정을 모두 처리했을 때를 비교하면 3가지 식중독 세균의 검출률에 있어서 차이가 없는 것으로 분석되었다(p<0.05). 또한, 제조 회사의 햄과 소시지류에서 분리한 L. monocytogenes 균주를 대상으로 유전적 다양성을 조사하기 위하여 PFGE를 실시한 바, 동일 가공장에서 분리된 균주들간 80% 이상의 높은 상동성을 가진 것으로 조사되었다. 이러한 결과에 비추어 볼 때 햄 및 소시지류 제조회사에서 식중독 세균의 제어를 위해서는 원료 및 제조단계에서부터 가공 과정에서의 교차 오염을 예방하기 위한 적절한 위생관리와 철저한 모니터링을 통하여 체계적인 식중독 세균에 대한 위생관리를 완성하여야 할 것으로 판단된다. This study was carried out to examine foodborne pathogenic contamination from 1,080 samples of cooked hams and sausages at 10 Korean processing facilities in 2010. The samples were collected from the six primary and additional sterilization products in same lot. To detect Salmonella spp., Staphylococcus aureus, Listeria monocytogenes and Clostridium perfringens in those products (n=1,080), the domestic standard method for Processing and Ingredients Specification of Livestock Products was used. As a result, Salmonella spp. was not detected in all 636 ham and 444 sausage samples. However, L. monocytogenes was detected in four (0.6%) ham and eight (1.8%) sausage samples from five manufactures. S. aureus was also only detected in 4 (0.6%) ham samples from two manufacturers, and C. perfringens was detected in 3 (0.5%) ham samples from three manufacturers, the contamination levels of these pathogens were less than 100 CFU/g. In conclusion, the results of this study indicate that the additional sterilization step of processing manufacturers could not assist to control the foodborne pathogenic bacteria.
