본 연구는 독일 베를린 마르찬 세계정원 내에 조성된 한국전통정원인 서울정원의 현지 이용객을 대상으로 한국정원에 대한 인지성과 정원의 선호요소, 인접한 중국, 일본 전통정원과의 인식차이를 중심으로 분석하였다. 서울정원은 앞서 조성된 중국정원, 일본정원보다 상대적으로 잘 알려진 것으로 나타났다. 마르찬공원 내에서의 한국정원의 특별성에 대한 인지도는 평균수준으로 타 국가의 전통정원과의 차별성을 인식하지 못하고 있었다. 이는 동양 3국의 전통정원이 공원 내에 인접하여 배치되어 있어 이용객들의 연속적인 관람이 이뤄지고 있다는 것과 자연형 배식기법의 적용에 따른 유사한 수종의 구성을 통해 경관이 연출되고 있는데서 그 원인을 찾을 수 있으며, 나아가 한국정원이 타 동양정원과 비교될 만한 독특한 공간구성, 식재 수종의 다양성과 대표성, 설계단계에서의 해당 국민의 동양정원문화에 대한 인지성 분석 등 다각적인 차별화 방안이 향후 제시되어야 함을 의미한다. 방문 전후 한국정원에 대한 이해도 결과는 사전정보 없이 방문한 이용객의 경우 한국정원에 대한 이해도가 높게 나타났고, 재방문 의사도 높게 나타나 서울정원이 한국전통정원의 홍보와 이해에 기여한 것으로 해석된다. 한국성을 표출하고 있는 서울정원의 선호요소 중 수경관의 폭포와 계류, 정자와 자연석에 대한 관심이 많은 것으로 나타났는데, 이는 설계개념에서 제시한 독락당과 별서정원의 입지구조, 독락당 전면 너럭바위와 계류를 모티브로 한 한국정원의 경관연출기법이 중국과 일본의 전통정원과 차별성을 가질 수 있다는 가능성을 보여준다. 물리적 환경에서 지배적인 정원 건축물에 대한 양식적 차이와 함께 한국적 자연경관 형성을 통한 정원의 연출은 외국인에게 독특한 정원요소로 인식될 수 있을 것이다.

본 연구는 유네스코 세계문화유산인 중국 강소성(江蘇省) 소재 소주고전원림(蘇州古典園林) 수경관(水景觀)을 조명한 결과이다. 문헌조사 및 현장조사를 통해 입수구와 출수구 그리고 주변 수경요소 간의 상호관련성을 정량적으로 탐색으로써 중국 고전원림 수구(水口) 고유의 객관적 특성을 파악하는 한편, 한국 전통원림과의 차이점을 준거할 수 있는 기초자료를 모색하고자 한 본 연구의 결과는 다음과 같다. 소주고전원림의 수공간 평균 면적은 1,680.7m²로 계상되었는데 이는 전체 원림면적의 21.3%를 차지하는 것으로 원림별 큰 편차를 보였다. 원림 대부분은 샘물과 우물을 수원(水源)으로 삼았으나 창랑정은 지표수를, 퇴사원은 계절수를 수원으로 하였다. 한편 원림의 수구는 정수구(正水口)와 가수구(假水口)로 구분되는바 가수구는 단지 의경(意景) 효과를 유도하기 위한 모방수구로, 수체계상의 의미를 중시하는 소주고전원림의 경향과 결착(結著)된 것으로 보임에 따라 궁극적으로 원림의 수구 배치는 전통 '감여이론(堪輿理論)ʼ이 작동되고 있음이 확인되었다. 그리고 소주고전원림의 인수(引水) 방식은 직인법(直引法), 명거법(明渠法), 침투법(滲透法), 관도법(管道法), 착정법(鑿井法) 등 5가지 유형이 적용되었다. 이중 직인법, 침투법, 관도법은 출수기법에서도 활용되었는 바 소주고전원림에서의 보편적인 물확보 수법인 침투법과 관도법은 국내 구분 방식으로는 집수법(集水法)과 인수법(引水法)에 비견(比肩)된다고 판단하였다. 그러나 한국 전통정원에서 보이는 현폭(懸瀑)과 비폭(飛瀑) 등의 입수기법은 발견되지 않으며 단지 자일(恣逸)과 잠류(潛流) 그리고 용출(湧出) 기법에 의존한 입수기법이 주로 적용되었고, 무너미를 통한 출수기법은 소주고전원림에서는 발견되지 않았다. 한편 소주고전원림의 입수구와 출수구에서 정태수체는 호수, 소(沼)와 담(潭)이 주류를 이루었으며. 동태 수체는 계류, 폭포와 샘으로 분류되는 가운데 3개 원림의 수공간은 원심적분산배치를, 6개소의 수공간은 구심적 집중배치에 따른 수경관 효과가 반영되었다. 그리고 수경관 연출기법으로 입수구에서는 '격(隔)ʼ과 '파(破)ʼ의 기법이, 출수구에서는 '엄(掩)ʼ과 '파(破)ʼ의 기법이 주로 적용되었다. 예컨대 입수구 주변에는 대부분 교량이 건립되고 사(榭), 헌(軒), 각(閣), 정(亭), 랑(廊) 등이 조성되었으며 첩석박안(疊石駁岸)으로 수구를 은폐한 경향이 감지됨에 따라 "비록 인간이 만들었지만 마치 하늘이 내린 것 같다(雖由人作, 宛自天開)"라는 소주원림의 이수사상(理水思想)을 구현한 것으로 이해된다. 마지막으로 입수구와 출수구의 시각구성상 은폐 및 노출 정도를 분석한 결과, 창랑정의 어비정과 환수산장 문천정 조망점에서만 수구가 노출될 뿐 다른 조망점에서는 수구가 가려져 있음을 확인할 수 있었다. 이와 같은 결과를 볼 때 소주고전원림 수구에서는 한국 전통정원에서 적용되고 있는"물이 들어오는 것은 보이나, 나가는 것은 보이지 않게 한다"는 풍수좌향론 관점에서의 '향향팔미법(向向發微法)' 기법은 거의적 용되지 않은 것으로 판단된다.

Since seagrasses are highly productive and provide a source of organic carbon for a wide variety of marine organisms in coastal and estuarine ecosystem, accurate assessment of seagrass production is critical to understand the functions and values of seagrasses in these ecosystems. Zieman's leaf marking technique has been mostly used to estimate seagrass leaf production rates. However, inherent problems on the traditional leaf marking technique have been discussed by the several researchers, and these problems can cause underestimation of seagrass production. To develop an accurate and reliable assessing method for seagrass production, production rates of eelgrass, Zostera marina in three bay systems on the south coast of the Korean peninsula were estimated using the conventional leaf marking technique and the plastochrone method. The plastochrone method has been recently suggested as an effective method for reliable assessments of seagrass production. In the present study, leaf production rates estimated by the plastochrone method were significantly higher than the rates derived from the traditional leaf marking technique. Annual eelgrass leaf production assessed using the leaf marking technique was about 65 to 89% of the estimated production using the plastochrone method. The differences in annual productions between assessment techniques imply that the conventional leaf marking technique significantly underestimated eelgrass leaf production. Total eelgrass productions estimated using the plastochrone method in the present study sites were about 600 to 806 g DW $m^{-2} y^{-l}$, and below-ground production accounted for about 20 to 23% of the total production. The plastochrone method was suggested to be an effective and accurate assessing method for eelgrass production.

The purpose of this thesis is to discuss corsets that represent an undergarment that later became a popular outerwear. It discusses its forms and distinct characteristics to help create a unique fashion design and its execution. The scope of this study is limited to works from the 1990s to the present, and the materials for the literatures and exploratory study are fashion-related portfolios and the domestic and foreign fashion magazines. The results of this study are summarized as follows: The standard look of corsets in modern fashion can be classified into styles of glamour, revival, and dismantle. The materials used vary from traditional fabrics such as satin or lace to newly developed materials such as metal or glass. Its presentation can also differ in that it may be used as an accessory with additional details, as an outerwear, as an extra decorative layer, or as a revealing innerwear by open outerwear. Characteristics of these various looks of corsets are; first, it redefines the revival of the traditional corsets through introduction of its historic elements and its compromise. Second, glamorous and feminine images are maximized through drastic and direct exposure by using tight lacing, a waist nipper or garter belts that emphasize a woman's curve. Third, it represents borderless dismantlement through experimental and irregular images using unconventional materials, new execution techniques, or alteration from the standard forms.

Recently more than ever, interest in Korean tradition has been on the increase, with an active movement to follow tradition. There are various merits for expression with the use of Korean paper as a clothing material. The purpose of this study was to assess the aesthetic characteristics of men's shirts fashioned using Korean paper (Hanji). The following conclusions were obtained from an analysis of the aesthetic characteristics of Hanji shirts. First, Hanji has a peculiar texture, with natural characteristics due to the direct use of naturally handcrafted materials. Hanji shirts have the natural beauty of pure Hanji, without artificial treatment or other subsidiary materials, with the exception of thread. Secondly, Hanji shirts with decorative details and trimmings, such as frills, pin tuck, embroidery and spangles, express an ornamental beauty. Thirdly, Hanji shirts with frills or a fringe have real movement when worn and spangles give the illusion of movement due to changes in color or twinkling caused by light giving the beauty of rhythmical motion. Fourthly, Hanji shirts produced using the application of various techniques, such as crumple, painting and dying, express artistic beauty. Fifthly, Hanji shirts can express traditional beauty, even if created whit modem designs, but using traditional materials.

Structural system identification (SSI) is an inverse problem of difficult solution. Currently, difficulties lie in the development of algorithms which can cater to large size problems. In this paper, a parameter estimation technique based on evolutionary strategy is presented to overcome some of the difficulties encountered in using the traditional system identification methods in terms of convergence. In this paper, a non-traditional form of system identification technique employing evolutionary algorithms is proposed. In order to improve the convergence characteristics, it is proposed to employ immune algorithms which are proved to be built with superior diversification mechanism than the conventional evolutionary algorithms and are being used for several practical complex optimisation problems. In order to reduce the number of design variables, domain decomposition methods are used, where the identification process of the entire structure is carried out in multiple stages rather than in single step. The domain decomposition based methods also help in limiting the number of sensors to be employed during dynamic testing of the structure to be identified, as the process of system identification is carried out in multiple stages. A fifteen storey framed structure, truss bridge and 40 m tall microwave tower are considered as a numerical examples to demonstrate the effectiveness of the domain decomposition based structural system identification technique using immune algorithm.

Magnetic disks have been used for decades in auxiliary storage devices of computer systems. In recent years, the use of NAND flash memory, which is called SSD, is increased as auxiliary storage devices. However, NAND flash memory, unlike traditional magnetic disks, necessarily performs the erase operation before the write operation in order to overwrite data and this leads to degrade the system lifetime and performance of overall NAND flash memory system. Moreover, NAND flash memory has the lower endurance, compared to traditional magnetic disks. To overcome this problem, this paper proposes EPET (Enhanced Prediction and Elapsed Time) wear leveling technique, which is especially efficient to portable devices. EPET wear leveling uses the advantage of PET (Prediction of Elapsed Time) wear leveling and solves long-term system failure time problem. Moreover, EPET wear leveling further improves space efficiency. In our experiments, EPET wear leveling prolonged the first bad time up to 328.9% and prolonged the system lifetime up to 305.9%, compared to other techniques.

Taylor and Ford in the 1910s led to the "scientific management" for the entire industry from the manufacturing spread of TQM Total Quality Management has been structured as a management efficiency, such as 6-Sigma techniques were developed. SW development also introduces the idea, such as CMMI and SPICE-based process management, management practices have evolved. However, in recent years to increase the knowledge of workers in the manufacturing process oriented management approach is under serious challenge. Business performance or productivity will be varied depending all motivation, human relationship, job involvement rather than simply putting a lot of time. Especially in the SW industry which is depending on human resource, Creativity should be limited in traditional management methods. Recently, Google and Apple, Cisco and global advanced companies adopt a human relationship management. Their productivity and creativity in product development has been successful by giving autonomy and motivation, enthusiasm and vision to tile employees. Human relationship management since the mid-1990s, appears as a new paradigm so called Agile process in the field of SW development. Agile processes emphasis on light, flexible and responding to changes immediately in the business environment step away from traditional management approach which is the heavy and complicated process. In this paper, agile project management concepts and practices which is applied to industry will be examined.

Survival analysis mainly deals with the time to event, including death, onset of disease, and bankruptcy. The common characteristic of survival analysis is that it contains "censored" data, in which the time to event cannot be completely observed, but instead represents the lower bound of the time to event. Only the occurrence of either time to event or censoring time is observed. Many traditional statistical methods have been effectively used for analyzing survival data with censored observations. However, with the development of high-throughput technologies for producing "omics" data, more advanced statistical methods, such as regularization, should be required to construct the predictive survival model with high-dimensional genomic data. Furthermore, machine learning approaches have been adapted for survival analysis, to fit nonlinear and complex interaction effects between predictors, and achieve more accurate prediction of individual survival probability. Presently, since most clinicians and medical researchers can easily assess statistical programs for analyzing survival data, a review article is helpful for understanding statistical methods used in survival analysis. We review traditional survival methods and regularization methods, with various penalty functions, for the analysis of high-dimensional genomics, and describe machine learning techniques that have been adapted to survival analysis.

비디오 감시 시스템에서 정확한 물체 추적을 위해서는 움직이는 물체가 없는 정적인 배경 영상이 필수적이다. 하지만 기존의 배경 생성 방법들은 주로 시간 축에 따른 화소 정보를 이용하여 오랫동안 정지해 있는 물체들이 존재하는 경우에는 적용하기 어려운 단점이 있다. 이러한 문제점을 해결하기 위해 본 논문에서는 mean-shift와 fast marching method(FMM)을 이용해 시간 축 화소 정보와 공간 축 화소 정보를 이용하여 배경을 생성하는 방법을 제안한다. mean-shift를 이용해 시간 축에 따른 화소 값의 최빈값을 추정하여 배경을 생성하고, FMM을 이용해공간 축에 따른 화소 정보를 이용하여 일정 기간 동안 움직이지 않은 물체가 있는 환경에서 바람직한 배경을 생성한다. 실험 결과는 제안한 방법이 기존의 시간에 따른 빈도만을 이용하는 방법보다 더 효율적임을 보여준다.
