The purpose of this study is to compare growth condition of landscape woody plants growing on the different ground structures in apartment complex. I chose Manseok Beach Town Complex 2, in Manseok-dong, Seo-gu, Incheon which has both natural and artificial ground as a subject site. Analysis of three phases of soil showed that artificial ground had average liquid phase of 30.89%, artificial ground mounding 33.88% and natural ground 24.40%. It means that artificial ground has higher water content than natural ground despite having same earthiness. It is believed that artificial ground is not as well drained as natural ground even though it is connected to the natural ground and has a deep soil depth because of mounding. Comparative study between woody plants on natural ground and those on artificial ground demonstrated that trees on natural ground grew 40.4% compared to those on artificial ground(0.875mm more) in terms of diameter growth. Average diameter growth of trees on natural ground was 3.040mm against 2.165mm for those on artificial ground. All 19 tree species which were measured for root diameter growth showed similar or higher growth on natural ground than on artificial ground. When it comes to growth of height, arborvitae showed highest growth on natural ground, followed by Thuja occidentalis, Pinus strobus, Magnolia denudata, Diospyros kaki and Aesculus turbinata. I measured branch growth and rate of leaf adherence of Pinus strobus. Average annual rate of branch growth of woody plants on natural ground was twice as high as those on artificial ground. I could conclude that ground structure influences branch growth of Pinus strobus. Statistics analysis of tree damage demonstrated significant result, meaning that there is a difference in the average damage rate depending on structure of ground. In order to validate growth difference by planting ground, I conducted T-Test of growth of diameter, root diameter, branch and height on woody plants growing on natural and artificial ground. As a result, it is believed that there is a difference in the growth of trees depending on the ground structure. Putting all these results together demonstrates that woody plants on natural ground generally grow better than those on artificial ground, which means ground structure does have an influence on the environment of growth of trees.

Erythema nodosum is a nodular erythematous eruption predominently limited to the pretibial area but occasionally involving the arms or other areas. That is clinical entity defined easily but there are many different opinions about histopathologic findings, Recently erythema nodosum is characterized histopathologically by a septal panniculitis in which the fibrous septa of subcutaneous fat become inflamed. Erythema nodosum has been known to be frequently associated with some kinds of drugs, infections with streptococci, mycobacteria but in $60\%$, no cause is found, Treatment of erythema nodosum consists of supportive care and elimination of underlying causes. Because spontaneous resolution of the lesions can occur in 3 to 6 weeks. Although there are trial treatments are applied to erythema nodosum, ego corticosteroids, NSAIDs, potassium iodine, there isn't any definite. So We report a case of erythema nodosum which was not relieved by NSAIDS but by experimental acupuncture treatment.

최소평균사승 적응알고리즘은 추정오차의 평균사승값을 최소화하는 추정경도방법 가운데 하나이다. 알고리즘의 잠재적인 여러 장점에도 불구하고, 이 알고리즘은 현재 기존의 최소평균자승 알고리즘 보다 실제 적게 주목받고 있다. 그 이유는 최소평균사승 알고리즘의 수렴특성에 관한 통계적 분석이 최소평균자승 알고리즘에 비해 매우 어렵고, 따라서 아직 알고리즘에 대해 모르는 분분이 많이 때문으로 보인다. 본 논문에서는 적응필터의 입력신호가 평균이 영이고 시불변 가우시안 랜덤신호일 경우 최소평균사승 적응알고리즘의 통계적인 수렴특성에 대하여 연구하였다. 이를 위해, 시스템인지 모드에서 알고리즘의 평균 및 평균자승 특성을 나타내는 일련의 관계식을 유도하였다. 그리고 알고리즘의 평균특성이 수렴하기 위한 조건을 찾았는데, 여기서 최소평균사승 적응알고리즘의 수렴특성이 초기치의 선택에 크게 좌우됨을 알 수 있었다. 또한 최소 평균사승 알고리즘의 성능을 기존의 최소평균자승 알고리즘과 실험적으로 비교하였고, 두개의 알고리즘이 정상상태에서 같은 값의 평균자승추정오차를 갖을 때 최소평균사승 알고리즘이 치소평균자승 알고리즘에 비해 매우 빠른 수렴속도를 갖을수 있음을 확인하였다. The least mean fourth (LMF) adaptive algorithm is a stochastic gradient method that minimizes the error in the mean fourth sense. Despite its potential advantages, the algorithm is much less popular than the conventional least mean square (LMS) algorithm in practice. This seems partly because the analysis of the LMF algorithm is much more difficult than that of the LMS algorithm, and thus not much still has been known about the algorithm. In this paper, we explore the statistical convergence behavior of the LMF algorithm when the input to the adaptive filter is zero-mean, wide-sense stationary, and Gaussian. Under a system idenrification mode, a set of nonlinear evolution equations that characterizes the mean and mean-squared behavior of the algorithm is derived. A condition for the conbergence is then found, and it turns out that the conbergence of the LMF algorithm strongly depends on the choice of initial conditions. Performances of the LMF algorithm are compared with those of the LMS algorithm. It is observed that the mean convergence of the LMF algorithm is much faster than that of the LMS algorithm when the two algorithms are designed to achieve the same steady-state mean-squared estimation error.

조성호,박해석,조승화,임은정,양호연,하광수,김은지,양승조,정도연,Cho, Sung Ho,Park, Hae Suk,Jo, Seung Wha,Yim, Eun Jung,Yang, Ho Yeon,Ha, Gwang Su,Kim, Eun Ji,Yang, Seung Jo,Jeong, Do Yeon 한국미생물학회 2017 미생물학회지 Vol.53 No.1

전통방식으로 제조하는 전통 장류인 된장과 고추장은 제조하는 환경과 방법, 미생물 그리고 제조자에 따라 다양한 풍미와 특성을 나타낸다고 알려져 있다. 본 연구에서는 전통 된장과 전통 고추장의 미생물 분포도를 제주도(된장 2점, 고추장 2점), 전남권(된장 3점, 고추장 3점), 전북권(된장 7점, 고추장 5점)으로 구분하여 미생물(세균, 진균) 분포의 차이점과 유사점에 대해 차세대 염기서열 분석법을 이용하여 분석하였다. 분석시료는 종균을 이용하지 않고 자연발효 되었고, 1~5년간 발효 숙성된 제품으로 수집되었다. 전통 된장의 세균 분포도를 보면, 3개 지역에서 공통적으로 우점하는 세균은 B. amyloliquefaciens와 Tetragenococcus halophilus이었으며, Bacillus 속은 전남권(43.16%), 전북권(64.54%)에서 주요한 우점균 이었다. 그러나 제주도의 시료는 Bacillus 속이 0.22%로 내륙과 제주도는 현저한 차이를 보여주었다. 진균 분포도를 보면, Candida versatilis는 3개 지역에서 공통적으로 우점 하였으며, Candida 속은 전남권(64.22%), 전북권(33.68%)이었고, Mucor 속은 전북권(36.73%), 전남권(15.66%)의 주요한 우점종이었다. 그러나 제주도 시료는 곰팡이 보다는 효모인 Candida 속과 Zygosaccharomyces rouxii가 우점균이었다. 전통 고추장의 세균 분포도를 보면, 3개 지역에서 공통적으로 우점하는 세균은 B. subtilis와 B. licheniformis이며, B. amyloliquefaciens는 호남권에서만 우점종 이었다. 전반적으로 고추장에서 Bacillus 속이 우점균이라는 내용과 일치되는 결과를 나타냈다(Jin et al., 2007). 진균 분포도를 보면, 3개 권역의 고추장에서 공통적인 우점종이 없었으며, 제주도와 전남권은 Aspergillus 속과 Rhizopus 속이 우세하였고, 전북권은 Zygosaccharomyces rouxii가 우점종이었다. 이러한 결과는 본 연구를 위해 수집된 표본에서는 전통 된장과 전통 고추장은 지역적인 특징보다는 각 시료의 군집특성에 따라 유사 군이 형성된 것으로 사료되었다. 따라서 본 연구결과를 기반으로 하여 우리나라 전국적으로 표본을 수집하여 분석함으로써 보다 명확한 지역적, 시료 특성별 유사점과 차이점에 대한 미생물의 군집 분포도를 정의할 수 있을 것으로 예상되었다. In order to evaluate the diversity of microbial population of Korean traditional Deonjang and Gochujang produced in Jeju, Jeonnam, and Jeonbuk province area, microbial communities were analyzed using next generation sequencing. In this result, the dominant bacteria of Deonjang in three area were Bacillus amyloliquefaciens, Tetragenococcus halophilus, and Bacillus was major dominant bacteria in Jeonnam (43.16%) and Jeonbuk (64.54%) area. But in Jeju area, Bacillus was 0.22%, which was significantly different from the other two. Equally, the dominant fungi of Deonjang in 3 area were Candida versatilis. Common fungus in Jeonnam and Jeonbuk area was Candida sp., respectively, 64.22% and 33.68% and Micor sp. was a common fungus in Jeonnam (15.66%) and Jeonbuk area (36.73%). But in Jeju area, Candida sp. and Zygosaccharomyces rouxii were dominant than mold. Bacillus subtilis, Bacillus licheniformis, and B. amyloliquenfaciens were the preminant bacteria in the traditional Gochujang in three regions. But there were no common dominant fungi in the 3 regions. Aspergillus sp. and Rhizopus sp. prevailed in Jeju and Jeonnam region, and Zygosaccharomycess rouxii predominanted in Jeonbuk area. These results suggested that the difference in the samples collected for the study were classified into similar groups according to the characteristics of each sample rather than regional characteristics.

Subcutaneous cervicofacial, mediastinal emphysemas are complications associated with head and neck surgery, trauma, infectious processes, tooth extraction. Drill cooling stream and dental syringe air ject are the sources of high pressure air that may enter exposed soft tissue. Since the introduction of the high-speed air turbine drill in the 1960s, The incidence of iatrogenic subcutaneous emphysema has increased. Most cases begin to resolve after 2 to 3 days and residual swelling is usually minimal at the end of 7 to 10 days. Surgical approach is not advised because it is likely to be ineffective. The differential diagnosis of neck swelling after dental procedure includes hematoma, cellulitis, angioedema, allergic reaction, subcutaneous emphysema. We report a rare case of patient with subcutaneous cervicofacial emphysema and mediastinal emphysema secondary to third molar extraction.

조성호 ( Sung Ho Cho ) 한국지역언론학연합회 2006 언론과학연구 Vol.6 No.1

이 연구는 지역방송의 자체편성 프로그램을 분석하여 경쟁력 있는 프로그램을 확인하는데 목적이 있다. 이에 따라 4대 지역을 대상으로 장르별 편성 시간, 진행자의 유명인 여부, 방송 소재의 활용 폭, 프로그램 제작주체, 편성 시간대 등으로 구분해서 편성비율 및 시청률을 이용하여 경쟁력을 비교하였다. 지역방송은 정보(47.5%), 보도(35.0%), 오락(10.2%) 순으로 편성하고 있었다. 편성 프로그램의 경우 유명연예인을 활용한 편성방식이 경쟁력이 있는 것으로 나타났고 프로그램 대상소재도 MBC의 경우는 방송권역(4.0)이 지역민방과 KBS의 경우는 방송지역의 소재만을 활용한 경우가 경쟁력이 가장 높은 것으로 나타났다. 또한 권역공동제작이 자체제작이나 권역외 공동제작보다 시청률이 훨씬 높은 것으로 나타나 권역소재를 활용하고 권역공동제작을 했을 때 가장 경쟁력이 있는 것으로 판단된다. 보도의 경우는 SA급 시간대에 편성프로그램의 경우 A급 시간대에서 가장 경쟁력이 있는 것으로 나타났다. 마지막으로 지역프로그램이 동시에 편성될수록 시청률이 높아지는 것으로 나타났다. The purpose of this study is to identify competitive programs by analysing local broadcasting programming. It examined weekly television schedules of local programming for four major areas such as Busan, Daegu, Kwangju and Daejeon. The competitiveness of local program was analysed based on duration of program, genre, host of program, contents of program, origin of program production, and scheduled time. Further, it was compared with ratings. The results indicated that the proportion order of local programming time was ``information genre(47.5%),`` ``reporting(35.0%)`` and ``entertainment(10.2%),`` The comparison of ratings based on program genre indicated that the rating of reporting genre(6.4) was over twice more than that of entertainment genre(3.1) or information genre(2.9). Programs using famous host except reporting genre got more ratings than using local host. The most competitive programming method for MBC was using mid-wide area contents. However, in the case of private broadcasting using narrow area contents was the most competitive. In addition, the most competitive method for program production was self production or cooperative production in mid-wide area. Thus, the results suggested that using the mixed method of mid-wide contents and cooperative production was the most competitive. Finally, reporting genre had competitiveness in scheduling for SA time zone whereas the other genres was for A time zone.

This study is to suggest architectural types and characteristics of traditional style public buildings of reinforced concrete structure. Because the types of such buildings are very diverse, different from the case of residential architecture of the same style, proper classification criteria is essential for future design and evaluation. For each type of buildings classified by the degree of modern change from the traditional pattern, this paper compares and contrasts them under five different categories: building use, construction year, floor areas, stories, cost. The result of classification shows that among 44 buildings, the number of buildings that conserved the traditional character (classified as type A) was the largest (total 16) whereas that of the most abstract transformation from traditional (type D) was the least as 5. Partially transformed buildings which stand between conserved traditional and abstract traditional and were classified as type B and type C, each has 12 and 10 buildings. The number of these buildings has been increasing since 1990s and the purpose of buildings has expanded from exhibition and sports facilities to education and research facilities, medical facilities, and market places. The size of buildings are mainly 500-1,000㎡ and Construction cost per area of buildings found out to be mostly 500-1,000 ten thousand won per 3.3㎡. As a part of Korean modern architecture trend, there is a constant demand among people for the construction of these buildings with traditional origin, and there would be more of these type of building built in the future. Thus, we need a better way to determine size and cost of construction and direction of architectural design based on the architectural feature of original traditional building during the planning stage.
