향후 21세기는 지금껏 경험해 보지 못한 고령화 사회로서, 골다공증은 심혈관 질환 및 당뇨병에 이어 가장 중요한 노인 질환으로 대두 되어질 것이다. 그러므로 골다공증에 대한 조기 진단과 예방을 위한 진단방법은 매우 중요하나 잘못된 진단으로 조기발견을 놓칠 수 있게 된다. 여러장비 중 Radiographic Absorptiometry는 단순 X선 촬영을 통해서 피질골(손의 metacapal bone)의 두께를 측정하는 방법으로 간단하지만 약간의 오류를 갖고 있어 검사부위의 변환을 통해 결과값을 연구하고자 한다.

The Younsijo is a stream of Korean poem. not simply an aggregate of stanzas, but an organic structure. Younsijo was an appeared in the 16th century. The 16th century was focused on the literature of Sadaebu (noble family, 사대부). And the make an appearance is Danhyungsijo (simply-sijo, 단형시조), Yonsijo and Kasa(가사). In that case, a social stratum is why does singing each other form. The 16th century set metaphysics(성리학) as the national ideology. Metaphysics became most prevalent at the end of the 16th century. Yonsijo also appreared during the 16th century and was closeiy related to the idea of metaphysics. Both Younsijo and metaphysics were formulated by noble family, The Yonsijo was Formed in 16th century. And the 17th century was succession. The Yonsijo in 16th century is devide to Kanghosijo (강호시조) and Hunminsijo (훈민시조). Also, Kanghosijo is devide to Youkgaline Younsijo (육가계 연시조) and Sasigaline Yonsijo (사시가계 연시조). Hunminsijo used an expressive on the order of Oryoun(오륜). Therefore, this study is forced on , , and . These things, all of the end of the utility. This paper deals with Danhyungsijo and Kasa with main emphasis on works of Songgang(송강) Jungcheol(정철). The reason for dealing one writer's works is the discussion needs consistent standard. In analyzing Songgang's Danhyungsijo, Younsijoand and Kasa, one would discern the differences among three. As a result, one could conclude that both Danhyungsijo and Kasa mainly projects individual's emotional esthetic feeling, particularly, Danhyungsijo for emotional implication, and for in-depth emotional revealing. Younsijo were chosen as it supplements the shortcoming of Sijo(as it consists of three-line only) to effectively contain the ideas of metaphysics.

The imagery of Ophelia appeared in Russian literature in the middle of the $19^{th}$ century. In contrast with Hamlet, whose name had been always in the center of the most intense debates through centuries, Ophelia had been understood relatively monotonously and simply associated with the images of a chaste maiden, a tragic heroine and a devoted lover. Only after the feminist literary criticism shed new light on the complicated inner world of the young girl, the imagery of Ophelia radically changed, and now it is not difficult to encounter various Ophelias on the contemporary stages and culture. In this paper we study the remarkable changes of the imagery of Ophelia in Russian modernism poetry, analysing A. Blok, A, Akhmatova, M. Tsvetaeva's Ophelia poems. Ophelia in Russian modernism, on the one hand, succeeding to the traditional view on Ophelia in $19^{th}$ century, assumes interesting new aspects, sometimes preempting feminist point of view.

This article is a follow-up on the concept of philosopher/writer and its transformation in the Age of Enlightenment - 1. the dictionary meaning of the term 'philosopher/writer' and the origins of 'literary fields' of the Enlightenment era. In this article, we analyzed changes in the literary field in the late $17^{th}$ century after the expansion of the publishing market. We examined the conflict surrounding philosophers' identifying between modern and traditional philosophers. We have validated that the formation of new readers has made traditional philosophers more sensitive to the 'horizon of expectations' of readers. Some biographical works are also one of our concern. By the end of the $17^{th}$ century, philosophers and writers suddenly became objects of biographical works unlike in the past. Through our research, we found that readers have sought the arrival of a new hero, a great philosopher or a great writer, that will lead a new era, and due to this anticipation, it has led to the publication of biographical works. In this process, we have revealed conceptual changes about authors, writers, philosophers, and so on. In the next article, we will continue advanced discussion on the concept of philosopher/writer.

While American acoustics had been lagged behind European one in the nineteenth century, Alfred Mayer greatly contributed to enhance American experimental acoustics. He inherited experimental skills in collaboration with Koenig in Paris, and got chances to obtain research ability from leading researchers such as Rayleigh during his visit to England. His accomplishments, which brought him fame in Europe, included the creation of the acoustic pyrometer which measured the high temperature by means of the thermal change of the sound velocity, the discovery of mosquito's hearing by selective resonance, the formalization of the duration of the residual sensation of sound, the invention of the topophone which searched for the direction of the sound source, the construction of the apparatus for visualizing the frequency of sound and so on. He not only added new research results to Europe's acoustics but applied acoustics to physical education to help produce the next generation of American acousticians.

KSTAR(Korea Superconducting Tokamak Advanced Research) 토카막에 설치되어 있는 ICRF(Ion Cyclotron Range Frequency) 시스템을 이용한 방전세정을 2008년에 이어 2009 KSTAR 플라즈마 campaign 동안에도 시행하였다. ICRF 시스템을 이용한 방전세정인 ICWC(Ion Cyclotron Wall Cleaning)는 ITER와 DEMO 같은 초전도 자석을 이용하는 토카막에서 토카막 shot 중간에 자장을 낮추지 않고 바로 방전 세정을 할 수 있는 방법이다. 토카막에서 방전세정은 탄소나 산소 화합물과 같은 불순물을 제거하여 방사에 의한 플라즈마 냉각을 막고 토카막 초기 start-up시 진공 챔버 벽면으로부터 의도하지 않은 연료주입을 제거하는 역할을 한다. 본 연구에서는 ICWC 방전 세정 플라즈마의 밀도특성과 균일도를 간섭계와 $H_{\alpha}$ line 세기를 통해 관측하고 RGA를 통해서 C, $H_2O$, $O^2$ 불순물의 제거량을 파악하는 한편 토카막의 신뢰성 있는 start-up을 위해 요구되는 벽면에서 토카막 방전가스의 제거량을 HD양을 통해서 조사하였다. 플라즈마 선적분 밀도는 약 $1{\sim}3{\times}10^{17}#/m^2$로 측정되었는데 이는 보통 He을 이용한 방전세정 플라즈마의 밀도에 해당한다. 한편 $H_{\alpha}$ line의 세기를 통해 ICWC 방전 플라즈마의 균일도를 살펴본 결과 안테나 전류띠의 중간이 아닌 끝부분에서 $H_{\alpha}$의 세기가 큰 것으로 나타났는데 이는 ICWC 플라즈마가 Inductive 방전보다는 capacitive 방전에 의해 생성되는 것으로 추정된다. ICWC 방전에서 C, $H_2O$, $O_2$ 불순물의 제거율은 각각 약 $4.2{\times}10^{-5}\;mbar{\cdot}l/sec$, $1.4{\times}10^{-3}\;mbar{\cdot}l/sec$ 그리고 $1.72{\times}10^{-4}\;mbar{\cdot}l/sec$로 각각 나타났는데 ICWC shot이 진행될수록 이 양은 점점 줄어들었다. 대표적인 He/$H_2$, He ICWC 방전 shot인 2118, 2123 shot에서 벽면에서 $D_2$의 제거율은 각각 약 $0.12\;mbar{\cdot}l/sec$와 $3.9{\times}10^{-3}\;mbar{\cdot}l/sec$로 나타났다. 이는 수소의 첨가로 인해 HD의 형태로 $D_2$의 제거율이 증가되었기 때문이다. 한편 $H_2$의 첨가는 챔버 벽면에 흡착되는 $H_2$ 양을 또한 증가시키므로 차후에 $H_2$ 만을 제거하는 He ICWC를 수행해야 할 것이다.

Following the previous study focused on the period until the middle of the 20th century, this study tried to show how STS-related ideas have been developed historically in British science education, particularly focused on the period of the 2nd half of the 20th century. Like the USA, the UK witnessed the development of numerous academically-oriented programs, such as Nuffield projects, during the 1950-60s. However, during the 1970s, there had been growing criticism against the discipline-centered science education and some new noticeable approaches had been made to compensate the contemporary trend. For example, although its main focus was on the integrated approach in school science, the SCISP was quite successful to illustrate the importance of the relationship between science and society. Following this example, Science in Society and SISCON-in-Schools were more ambitious in developing genuine STS programs. These two projects were developed simultaneously and took the form of modules, rather than of textbooks. Nevertheless, Science in Society was more concerned with the applied and industrial aspects of science while SISCON-in-Schools was more inclined to the historical, philosophical and social aspects of science. During the 1980s, far more ambitious attempts had been made to develop full-scale STS programs, i.e. Salters' Chemistry/Science and SATIS. These two programs have been developed with the active corporation from the ASE and soon became the typical examples of the STS approach across the world. Besides the similarities between them, Salters' approach is more application-oriented, subject-oriented, and textbook-like while SATIS is more socially-oriented, issue-oriented and module-style. In summary, the history of STS approach in school science shows that the STS programs were developed under the different social backgrounds and initiated by different groups of the people who have different views towards the purposes of school science and that the STS approach is certainly not the exclusive characteristic of the last period of the 20th century. Finally, the features of the major STS programs developed in Britain during the 20th century are summarized and compared in relation to the Ziman's criteria of the possible approaches in STS education. And some general conclusion are drown based on the study of the history of the STS approaches in Britain.
