The aim of this study was to analysis the landscape equipments of 42 school gardens in Taejon metropolitan city. Outdoor educational landscape equipments were found out at 10 schools out of 42 schools. The materials of main entrance were consisted of steel and stone at 19 schools. The stands at front of the main ground were existed at 21 schools. The pergolas and benches were existed at 20 schools. The living material fences were found out at 21 schools. Plant nameplates were found out at 22 schools. But the contents of the nameplates were so poor. The wetland and roof garden of the school were not existed. School landscape equipments should be introduced by the distinction of elementary school, middle school, and high school as well as by the space of the school site.

Immobilization after a fracture has a therapeutic aspect of treating the fracture, but has problems such as joint restriction and muscle atrophy. One case was a 64-year-old male with ankle dorsiflexion restriction and ankle and plantar pain after ankle immobilization (splint and cast) for about 6 weeks. He was treated with acupuncture, electronic moxibustion, chuna therapy, and pharmacoupuncture and improved. Another one case was a 52-year-old female who underwent immobilization for 4 weeks after a 5th toe fracture, her pain and gait abnormality improved after acupuncture and chuna therapy.

Purpose: Facial palsy is one of the major disease that patients want to be treated by Korean medicine nowadays. Unfortunately, however, it is difficult to quantitatively measure symptoms of facial palsy. This study intends to measure facial movements and detect data through algorithms, compare and analyze them with the evaluation of Korean medicine doctors, and use them as basic data for application development. Methods and Results: This is a protocol for the study of 3D videography of facial movement and analyzing algorithms. A total of 50 eligible participants with facial palsy will be recruited from Dongguk University Bundang Hospital. The trial will include two steps of screening and assessment. All particiapants will be informed to answer basic facial palsy questionnaire and the facial disability index (FDI) questionnaire. Then, they will proceed with videography. Several Korean medicine doctors will evaluate participant's Housebrackman grade, Yanagihara score and Sunnybrook scale based on the video records. Also, through the recorded actual facial movements, algorithms will detect the datas. Finally it will be compared and analyzed with the evaluation of Korean medicine doctors. Conclusion: The result of this trial will provide a basis for the quantitative measurement of facial palsy, supplementing errors in existing facial paralysis diagnosis in clinical settings. Trial Registration: This protocol has been registered in the Clinical Research Information Service (CRIS) with the identification code KCT0008882.

Two cases of concurrent facial paralysis after facelift were reported. One case was a 64-year-old woman with facial paralysis of the left middle and lower face. After about 3 months of acupuncture, electroacupuncture, pharmacopuncture and physical therapy, motor and sensory abnormalities improved. One case was a 41-year-old woman who visited the hospital with motor dysfunction and paresthesia on the left zygomatic and buccal branch. After 2 weeks of treatment, she discontinued her patient visit without significant improvement. In real world, cosmetic procedures are widely practiced. Although this study is only a case report of two cases, one of the significances of this report is that these cosmetic procedures should be considered while identifying the cause of facial paralysis.

Recently, as the stock market continues to boom, the number of investors participating in the stock market is increasing. Although investment should be able to understand the figures of various indicators for stocks, the interfaces and visualizations of existing stock platforms such as HTS and MTS make it difficult for novice investors to accept information. In this paper, we propose an analysis and visualization service for stock portfolio using gamification to compensate for these problems. It presented a stock market information platform that can effectively provide information on the stock market to novice investors in real time by designing information delivery through dynamic effects in the 3D environment with layering methods and providing information such as correlation indicators between social interst and stock indicators, sentiment indicator of stock using news article.
KOH Etching을 통한 4H-SiC Epitaxy 박막에서의 전위결함 거동
신윤지,김원정,문정현,방욱,Shin, Yun-Ji,Kim, Won-Jeong,Moon, Jeong-Hyun,Bahng, Wook 한국전기전자재료학회 2011 전기전자재료학회논문지 Vol.24 No.10
The morphology of etch pits in commercial 4H-SiC epi-wafer were investigated by molten-KOH etching. The etching process was optimized in $525{\sim}570^{\circ}C$ at 2~10 min and the novel type of etch pits was revealed. This type of etch pits have been considered as TED (threading edge dislocation) II, its origin and nature, however, are not reported yet. In this work, the morphology and evolution of etch pits during epitaxial growth were analyzed and the different behavior between TED and TEDII was discussed.
4H-SiC와 산화막 계면에 대한 혼합된 일산화질소 가스를 이용한 산화 후속 열처리 효과

4H-SiC power metal-oxide-semiconductor field effect transistors (MOSFETs) have been developed to achieve lower specific-on-resistance (R<sub>on,sp</sub>), and the gate oxides have been thermally grown. The poor channel mobility resulting from the high interface trap density (D<sub>it</sub>) at the SiO<sub>2</sub>/4H-SiC interface significantly affects the higher switching loss of the power device. Therefore, the development of novel fabrication processes to enhance the quality of the SiO<sub>2</sub>/4H-SiC interface is required. In this paper, NO post-oxidation annealing (POA) by using the conditions of N<sub>2</sub> diluted NO at a high temperature (1,300℃) is proposed to reduce the high interface trap density resulting from thermal oxidation. The NO POA is carried out in various NO ambient (0, 10, 50, and 100% NO mixed with 100, 90, 50, and 0% of high purity N<sub>2</sub> gas to achieve the optimized condition while maintaining a high temperature (1,300℃). To confirm the optimized condition of the NO POA, measuring capacitance-voltage (C-V) and current-voltage (I-V), and time-of-flight secondary-ion mass spectrometry (ToF-SIMS) are employed. It is confirmed that the POA condition of 50% NO at 1,300℃ facilitates the equilibrium state of both the oxidation and nitridation at the SiO<sub>2</sub>/4H-SiC interface, thereby reducing the Dit.

Objectives: This study was performed to evaluate the quality of case reports from the Maternal and Child Health Care & Functional Medicine and Nutrition Association in accordance with CARE (CAse REport) guidelines. Methods: Researchers selected case reports of Maternal and Child Health Care & Functional Medicine and Nutrition Association in the database of Google Scholar. The quality of selected reports was assessed based on CARE guidelines. Results: Total of 12 case reports were included in this study. Reporting rate of each sub-items was 92.59% at the maximum, 62.96% at the minimum, 77.42% at the median. ‘7 Time line’, ‘8b Diagnostic challenges’, ‘10c Intervention adherence and tolerability’, ‘10d Adverse and unanticipated events’, ‘12 Patient perspective or experience’, ‘13 Informed consent’ were missed in more than 50% of the reports. Conclusion: For improvement of the quality of case reports, it is necessary to evaluate case reports from the Maternal and Child Health Care & Functional Medicine and Nutrition Association in adherence to CARE guidelines.
