This paper has aimed to determine how the Suwon Palkyong(水原八景: eight scenic wonders) were formed and the implicature of landscape, such as implicit intention and symbolic significance. For this, the significance and symbolic meaning of the Suwon Palkyong from the time of the 'Hwaseong Chunchu Palgyeong(華城春 秋入景)' have been investigated in order to determine the political and social arguments in Suwon Palkyong that surrounded the formation process and meaning. The 'Hwaseong Chunchu Palkyong' contains a variety of significant elements and factors of Pungmul(Korean drum & dance) as well as formative elements such as a castle. Plantings for beautiful scenery and water use for flood control have also been major elements in the development of Hwaseong. Therefore, it seems that the 'Hwaseong Chunchu Palkyong' is a catchphrase for the future image of the urban landscape. Most Suwon Palkyong sites such as Paldalsan, Namje, Yungneung, Manseokgeo, Chukmanje, Hwahongmun, and Yongji(a pond in Banghwa Suryujeong) are related to the 'Hwaseong Chunchu Palkyong'. 'Gwanggyo Jeokseol(光敎積雪: the landmark mountain, Mt. Gwanggyo with snow)' and 'Paldal Cheongnam(八達晴嵐: Mt. Paldal with shimmering air)' have also been added to Suwon Palkyong. Suwon Palkyong is either directly or indirectly related with water including the origin of Suwoncheon(水原川), an artificial reservoir for flood control and irrigation and Bibopungsu in Yungneung(隆陵), as well as the source of water for rituals after the death of King Jeongjo(正祖大王). Based on Suwon Palkyong, therefore, it can be said that water is a decisive medium in connecting old Suwon with Hwaseong New Town and essential element in the natural landscape. In conclusion, while Hwaseong is a 'Designed Landscape' that was created with a specific intention during the reign of King Jeongjo, the 'Hwaseong Chunchu Palkyong is a 'Desired Landscape' that envisioned a future landscape while Suwon Palkyong is an 'Evolved Landscape' related to the business affairs of the citizens. To completely restore Hwaseong, whose value and importance have been recognized internationally, therefore, the fundamental restoration of a cultural landscape as well as the restoration of the original form of the Hwaseong landscape including Suwon Palkyong is essential.

The Mevelana sect is a spiritual Islamic group experiencing spiritual transaction with their god through a peculiar dancing as a form of religious ritual. The Mevelana, a sect of Islamic Sufism, has their head mosque in Konya in Turkey. Although Mevelana sect is regarded as heretic of Islam, it has exerted considerable influence on the Islamic religion through its peculiar religious worshiping form constituted in dancing and reciting poems. Nowadays, Turkey recognizes the Mevelana dancing as their precious cultural legacy of a long history, exerting public information efforts to give it for wider publicity of Turkey to the world. The Mevelana dress with ornament attired for the ritual dancing performance is regarded to symbolize a spiritual medium, which leads to conciliation with the eternity. The straight lines and curved line characteristic of the Mevelana dancer's trousers, skirt, jacket and such mirrors the image of the Orientals, which is in peculiar contrast with the white and gray colors of the dress with ornament. The impression of the spiritual Mevelana dressing in harmony with the dynamic dancing motion goes beyond mere a religious dressing. It is expressive of a graceful and sophisticated modern formative art, of which the mystic design gives an inspiration to the modern fashion. After Poiret, Islamic factors have emerged in the modern fashion. For instance, a hat with Arabic fashion lapel, a Fez hat of Turkish style, harem pants and such are still popular in the modern fashion. It seems probable that the Iraq War would far more activate the influence of Arabic culture to the modern fashion. By making an analysis on the religious background and formative characteristics of the Mevelana dressing, and by giving design examples on how the Mevelanan dressing has been applied to the modern fashion, this research suggests working out new designs by making a renewed application of their characteristics to the modern fashion.

When performing remote tasks using robots in nuclear power plants, a 3D shape measurement system is advantageous in improving the efficiency of remote operations by easily identifying the current state of the target object for example, size, shape, and distance information. Nuclear power plants have high-radiation and underwater environments therefore the electronic parts that comprise 3D shape measurement systems are prone to degradation and thus cannot be used for a long period of time. Also, given the refraction caused by a medium change in the underwater environment, optical design constraints and calibration methods for them are required. The present study proposed a method for developing an underwater 3D shape measurement system with improved radiation tolerance, which is composed of commercial electric parts and a stereo camera while being capable of easily and readily correcting underwater refraction. In an effort to improve its radiation tolerance, the number of parts that are exposed to a radiation environment was minimized to include only necessary components, such as a line beam laser, a motor to rotate the line beam laser, and a stereo camera. Given that a signal processing circuit and control circuit of the camera is susceptible to radiation, an image sensor and lens of the camera were separated from its main body to improve radiation tolerance. The prototype developed in the present study was made of commercial electric parts, and thus it was possible to improve the overall radiation tolerance at a relatively low cost. Also, it was easy to manufacture because there are few constraints for optical design.

Increasing the gene copy number has been commonly used to enhance the protein expression level in the yeast Pichia pastoris. However, this method has been shown to be effective up to a certain gene copy number, and a further increase of gene dosage can result in a decrease of expression level. Evidences indicate the gene dosage effect is product-dependent, which needs to be determined when expressing a new protein. Here, we describe a direct detection of the gene dosage effect on protein secretion through expressing the enhanced green fluorescent protein (EGFP) gene under the direction of the ${\alpha}$-factor preprosequence in a panel of yeast clones carrying increasing copies of the EGFP gene (from one to six copies). Directly examined under fluorescence microscopy, we found relatively lower levels of EGFP were secreted into the culture medium at one copy and two copies, substantial improvement of secretion appeared at three copies, plateau happened at four and five copies, and an apparent decrease of secretion happened at six copies. The secretion of EGFP being limiting at four and five copies was due to abundant intracellular accumulation of proteins, observed from the fluorescence image of yeast and confirmed by western blotting, which significantly activated the unfolded protein response indicated by the up-regulation of the BiP (the KAR2 gene product) and the protein disulfide isomerase. This study implies that tagging a reporter like GFP to a specific protein would facilitate a direct and rapid determination of the optimal gene copy number for high-yield expression.

We analyzed the line profiles of the planetary nebula (PN) NGC 7009 secured with the Keck I HIES and BOES's spectral data. The 5 positions were taken over the nebular image, 4 points on the bright rim plus 1 point at the central position. The covered spectral wavelength range was $3250{\AA}-8725{\AA}$ in these observations. We decomposed the lines of HI, HeI, HeII, CII, NIII, [ClIII], [NII], [OII], [OIII], [SII], [SIII], [ClIII], and [ArIII] using the IRAF and StarLink/Dipso. After correcting the Earth's movement and the PN's radial velocities, -48.6 & -48.9 km/s, respectively, for the Keck & BOES, we produced the line profiles in a velocity scale. The zero velocity at each line profile clearly indicates which part of the components is approaching or receding, giving a general information of the kinematical structure. Almost all of the low-to-medium excitation lines, such as [NII], [SII], [O III], and [ArIII], secured at the central position and four positions along the major & minor axes, showed 3 components, double peak + a wide wing component, suggesting the fast outflow structures are present. The overall geometry is a prolate shell which also has a fainter outer shell in the halo zone, but there appears to be some peculiar sub-structures inside the main shell. The high excitation He I, HeII, NIII lines which might be formed close to the inner boundary of the shell show unusual features, completely different from the other lines. The HeII and these high excitation lines may be indicative of a relative recent fast outflow from the central star and the permitted lines such as NIII might be affected by the innermost structure. We discuss a possible presence of a jet-like fast outflow structure in an out-flow axis different from the main axis of the spheroid shell.

The hospital situation, timing, and patient restrictions have become obstacles to an optimum therapy session. The crowdedness of the hospital might lead to a tight schedule and a shorter period of therapy. This condition might strike a post-stroke patient in a dilemma where they need regular treatment to recover their nervous system. In this work, we propose an in-house and uncomplex serious game system that can be used for physical therapy. The Kinect camera is used to capture the depth image stream of a human skeleton. Afterwards, the user might use their hand gesture to control the game. Voice recognition is deployed to ease them with play. Users must complete the given challenge to obtain a more significant outcome from this therapy system. Subjects will use their upper limb and hands to capture the 3D objects with different speeds and positions. The more substantial challenge, speed, and location will be increased and random. Each delegated entity will raise the scores. Afterwards, the scores will be further evaluated to correlate with therapy progress. Users are delighted with the system and eager to use it as their daily exercise. The experimental studies show a comparison between score and difficulty that represent characteristics of user and game. Users tend to quickly adapt to easy and medium levels, while high level requires better focus and proper synchronization between hand and eye to capture the 3D objects. The statistical analysis with a confidence rate(α:0.05) of the usability test shows that the proposed gaming is accessible, even without specialized training. It is not only for therapy but also for fitness because it can be used for body exercise. The result of the experiment is very satisfying. Most users enjoy and familiarize themselves quickly. The evaluation study demonstrates user satisfaction and perception during testing. Future work of the proposed serious game might involve haptic devices to stimulate their physical sensation.

저궤도 위성영상 정보의 절대 대기 보정 처리에 의하여 산출되는 지표 반사도는 정확한 식생 분석에 필요한 기본 자료이다. Committee on Earth Observation Satellites (CEOS)는 사용자가 바로 활용할 수 있도록 하는 지표 반사도의 분석 대기 자료(Analysis Ready Data: ARD) 구축과 관련한 연구와 지침 개발이 수행되고 있다. 그러나 이러한 동향은 중저해상도 위성영상을 대상으로 하고 있어서 KOMPSAT-3A나 CAS-500과 같은 고해상도 분광 영상의 ARD를 다루는 연구는 아직 초기 단계이다. 이 연구는 우선 기존 사례를 바탕으로 하여 ARD 자료의 배포 방식을 정리하였다. 그리고 클라우드 환경에서 운영되는 위성 정보 응용 플랫폼 중의 하나인 오픈 데이터 큐브(Open Data Cube: ODC)와 ARD 자료와의 연계성을 설명하였다. 연구의 결과로 고해상도 위성영상의 실무적인 ARD 구축 단계와 ODC와 클라우드 환경에서 배포되는 고해상도 위성영상의 ARD 구축 모델과 몇 가지 유형의 개념적 수준의 응용 모델을 제시하였다. 한편 제시한 구축과 응용 모델에 대하여 데이터 가격 정책, 정확도 품질 문제, 플랫폼 적용성 문제, 클라우드 환경 문제, 국제 교류 이슈 등을 토의 사항에서 정리하였다. 지구관측 위성과 관계된 주요 국제기구인 Group on Earth Observations (GEO)와 CEOS등에서 ARD와 ODC의 확산을 위한 시스템 기술과 표준 개발을 지속하고 있으며 이러한 성과는 민간부문으로 확대되고 있다. 따라서 우리나라도 이러한 국제 추세에 대한 대응 전략을 마련할 필요가 있다.
