예술의 새로운 표현양식으로서 또는 매체와 장르의 형식적 실험이라는 측면에서 회화와 사진은 영향을 주고 받으며 발전해 왔다. 최근 연극, 영화, 미술, 사진, 문학, 무용, 음악등의 다양한 예술분야가 혼합된 혼성장르 또는 개념으로서의 다원예술(Interdisciplinary Art)은 문화적으로 남용되고 있으며 내용보다는 무분별한 디지털 프로세스 기반의 융합을 통한 시각적 표현작업들이 다원주의적 예술로 인식되고 있다.

Several studies investigating the behavior and environmental distribution of rare earth elements (REEs) have been reviewed to determine the geochemical processes that may affect their concentrations and fractionation patterns in groundwater and whether these elements can be used as tracers for groundwater-rock interactions and groundwater flow paths in small catchments. Inductively coupled plasma-mass spectrometry (ICP-MS), equipped with an ultrasonic nebulizer and active-film multiplier detector, is routinely used as an analytical technique to measure REEs in groundwater, facilitating the analysis of dissolved REE geochemistry. This review focuses on the distribution of REEs in groundwater and their application as tracers for groundwater geochemistry. Our review of existing literature suggests that REEs in ice cores can be used as effective tracers for atmospheric particles, aiding the identification of source regions.

The aim of this review article is to summarize the role of titanium oxide ($TiO_2$) nanomaterials in the remediation of the aquatic environment contaminated with various emerging pollutants. The advanced oxidation process led by the semiconductor $TiO_2$ is an impetus in the remediation technology. Therefore, a vast number of literature works are available in this area. Further, the role of modified $TiO_2$ or thin film materials were discussed in the review. Also, the Localized Surface Plasmon Resonance (LSPR) effect of using noble metaldoped $TiO_2$ played an interesting role in the remediation process.

The purpose of this study is to clarify that critical writing can be a positive stimulus factor for the cultivation of critical thinking through actual cases of writing education targeting engineering students in universities. Critical writing education is a very important way to develop critical thinking necessary for acquiring scientific knowledge, sharing social values, creativity and cultivating new production capacity. Especially, when critical writing education is performed with materials that maintain critical view of social reality such as the movie "Bowling for Columbine", it is characterized by the fact that it is naturally combined with the dimension of engineering ethics faced by engineers from the analysis and judgment of social reality. This is an example of the fact that critical thinking education for engineering students does not necessarily meet their major areas.

The brightness of the Organic Light Emitting Diode (OLED) display is controlled by thin-film transistors (TFTs). Regardless of the materials and the structures of TFTs, an OLED suffers from the instable threshold voltage (V_th) of a TFT during operation. When designing an OLED pixel with circuit simulation tool such as SPICE, a designer needs to take V_th shift into account to improve the reliability of the circuit and various compensation methods have been proposed. In this paper, the effect of the compensation circuits from two typical OLED pixel circuits proposed in the literature are studied by the transient simulation with a SPICE tool in which the stretched-exponential time dependent V_th shift function is implemented. The simulation results show that the compensation circuits improve the reliability at the beginning of each frame, but V_th shifts from all TFTs in a pixel need to be considered to improve long-time reliability.

과거 영화가 예술성을 함유하며 동시대의 문학, 종교, 철학 등을 담아냈던 것과 달리 최근엔 외형적으로 흥미로운 구성과 자극되는 장면위주로 제작되고 있다. 좋은 영화란 흥미로운 스토리 밑에서 스며 나오듯 감독의 주제 메시지가 감동적으로 표현되며 동시대의 사회 면모에 대한 감독의 날카로운 시선인 사회의제를 공감할 수 있어야 한다. 코엔형제들의 영화를 살펴보면 아이러니와 해프닝을 통한 전형적인 블랙 코미디 장르의 오락 영화인 것 같으나 실제로는 자국의 사회문제를 영화 곳곳에 수없이 많이 삽입하며 관조적 시점에서 냉소적으로 자신들의 사회의제를 훌륭히 표현해 내고 있음을 볼 수 있다. 그들의 영화 "위대한 레보스키(1998)"를 보면 주인공 캐릭터들의 천덕스런 모습을 통해 코믹한 내용을 창출해 내고 있는 것 같지만 실제로는 사회 부적응 자를 양산한 역사적 사실에 대한 사회의제를 블랙코미디로 희화화하는 등 베트남전, 포스트모더니즘, 우민화정책 등 미국 사회문제 들을 섭텍스트(sub-text)로 표현하고 있는 감독의 탁월한 연출임을 알 수 있다. 이와 같은 문화적 파급력을 가진 영화를 분석함으로 한국의 영화산업의 진일보에 일조하기를 기대한다.

This study analyzes through the review of literature and laws the exposure time, clinical frequency, and radiation exposure of intraoral and extraoral radiography as well as of panoramic radiography performed by dental hygienists in dental clinics, compares the dental radiology curriculums of radiological science and dental hygiene departments, and proposes the expansion of dental hygienists' radiography operations. The radiology curriculums were compared between the radiological science and dental hygiene departments of colleges. For new analysis by radiography for dental diagnosis, the exposure time, radiation absorbed dose, effective dose, and number of days of natural radiation were compared by the type of oral radiation films and radiographical techniques proposed by domestic and international studies. The exposure time of panoramic radiography is 15 seconds and it takes about two minutes for completion, whereas the exposure time of the standard radiography is 0.2~0.8 seconds and it takes 10 times longer for completion of the radiography of full mouth than the panoramic radiography. The standard radiography can cause distortions of radiation at severely curved parts of dental arch and palatopharyngeal reflex. However, panoramic radiography can be performed even for lock jaw patients, causes less inconvenience to patients and is much simpler than the standard radiography. The percentage of dental clinics where radiography is performed by dental hygienists was 92.0%, and the percentage of standard film radiography by dental hygienists was 98% whereas the percentage of panoramic radiography by dental hygienists was 92%. For the absorbed dose which is an indicator of radiation exposure, the When the effective dose which is an indicator of the danger of radiation exposure was converted to the number of days of natural radiation, it was 3.3 days for panoramic radiography, but 13.9 days for the full mouth standard radiography by bisecting angle technique which was 4.2 times longer than the panoramic radiography. There were two colleges that had a dental radiology course with two credits in the departments of radiological science. The credits for dental radiology courses in the department of dental hygiene ranged varied by college, ranging from 3 to 8; on average, the theory course was 2.2 credits and the practice course was 2.02 credits. To summarize the above results, the percentage of dental clinics where panoramic radiography is performed by dental hygienists under the guidance of dentists is high. Panoramic radiography has become an essential facility for dental clinics. It is faster than standard film radiography and less dangerous due to low radiation exposure. Panoramic radiography is a simple mechanical job that does not require training of oral radiography by radiotechnologist. Because panoramic radiography is one of major operations which must be performed at all times in dental clinics, it must be designated as intraoral technique rather than extraoral technique, or legalized for inclusion in the scope of operations of dental hygienists.

이상의 시와 그의 표상은 다양한 영상매체에서 활용되고 있다. 매체 및 장르의 특성에 따라 시인 이상의 표상과 그의 시는 각기 다른 방식으로 선택되며 변주된다. 문학이 다양한 매체들과 통섭하는 현대에서 한 시인의 초상이 어떻게 형상화되고 있는가를 검토하는 것은 텍스트가 한 인물을 통해 대중에게 전달하고자 하는 바를 읽어내는 과정이기도 하다. 본 연구는 시인 이상의 표상이 다양한 영상매체에서 활용된 양상을 검토하였으며, 각 텍스트들에서 시인 이상이 표상화되는 방식을 비교 분석하였다. 특히 영화 <건축무한육면각체의 비밀>과 드라마 <이상 그 이상>을 중심으로 논의를 진행하였다. 영화 <건축무한육면각체의 비밀>에서는 이상의 시를 사건의 단서가 숨겨진 퍼즐로 활용하고 있다. 이 영화는 대중적으로 널리 알려진 이상의 '천재' 표상을 활용하여 이상의 비밀을 추적하는 방식으로 서사를 전개하였다. 이로 인해 이 영화는 추리스릴러라는 장르의 관습에 충실한 방식으로 이상을 표상화하고 있다. 이에 비해 드라마 <이상 그 이상>은 시인 이상을 내면에 열정을 지닌 청년으로 새로이 표상하고자 하였다. 이상의 텍스트에서 드러나는 냉소적인 태도 또한 민족과 시대를 향한 애정의 이면으로 재조명하고 있는 것이다. 이러한 서로 다른 표상의 방식은 '이상'이라는 문학가의 대중적 인식과 새로운 표상화 시도의 전략이라는 측면에서 주목할 만한 가치가 있다.

A rigorous research is underway in our team, for the design and development of high figure of merits (ZT= 1.5${\sim}$2.0) micro-thermoelectric coolers. This paper discusses the fabrication process that we are using for developing the $Sb_2Te_3-Bi_2Te_3$ micro-thermoelectric cooling modules. It describes how to obtain the mechanical properties of the thin film TEC elements and reports the results of an equation-based multiphysics modeling of the micro-TEC modules. In this study the thermoelectric thin films were deposited on Si substrates using co-sputtering method. The physical mechanical properties of the prepared films were measured by nanoindentation testing method while the thermal and electrical properties required for modeling were obtained from existing literature. A finite element model was developed using an equation-based multiphysics modeling by the commercial finite element code FEMLAB. The model was solved for different operating conditions. The temperature and the stress distributions in the P and N elements of the TEC as well as in the metal connector were obtained. The temperature distributions of the system obtained from simulation results showed good agreement with the analytical results existing in literature. In addition, it was found that the maximum stress in the system occurs at the bonding part of the TEC i.e. between the metal connectors and TE elements of the module.

After its inception in 1994, the Journal of the Microelectronics and Packaging Society has continued to make significant strides in the number and quality of publications within its field. The interest in the microelectronics and packaging research has become more critical as consumer electronic products continue its increasing trend towards thinner and lighter devices that tests the boundaries of electronic devices. This study utilizes social network analysis of all published literature in the Journal for the past 22 years. Using the keywords and abstracts available within each individual article, the publications within the Journal has focused on major topics covering (1) flip chip, (2) reliability, (3) Cu, (4) IMC (intermetallic compounds), and (5) thin film. Using the social network relationship between keywords within articles, flip chip was closely associated with reliability, BGA (ball grid array), contact resistance, electromigration in many of the published research works within the Journal. From the centrality analysis, it was found that flip chip, reliability, Cu, thin film, IMC, and RF (radio frequency) to have a high degree of centrality suggesting these key areas of research have relatively high connectivity with other research topics within the Journal and is central to many of the research fields within the micro-electronics and packaging area. The cohesiveness analysis showed research clustering of five major cohesive sub-groups and was mapped to better understand the major area of research within this field. Research within the field of micro-electronics and packaging converges many disciplines of science and engineering. The continued evolution within this field requires an understanding of the rapidly changing industry environment and the consumer needs.
