For effective stimulation with tDCS, spatial focality of induced electrical field(EF) and current density(CD) is one of the important factors to be considered. Recently, there have been some studies to improve the spatial focality via different types of electrodes and their new configurations: some improvements using ring electrodes were reported over the conventional pad electrodes. However, most of these studies assumed isotropic conductivities in the head. In this work, we have investigated the effect of tissue anisotropy on the spatial focality of tDCS with the 4 + 1 ring electrode configuration via a 3-D high-resolution finite element(FE) head model with anisotropic conductivities in the skull and white matter. By examining the profiles of the induced EF from the head models with isotropic and anisotropic conductivities respectively, we found that the spatial focality of the induced EF significantly drops and get diffused due to tissue anisotropy. Our analysis suggests that it is critical to incorporate tissue anisotropy in the effective stimulation of the brain via tDCS.

1. Objectives : The aim of this study was to survey the ordinary symptoms of TE type(Tae-eumin) and to compare the tendency of their symptoms according to the Exterior- or Interior- disease. 2. Methods : We recruited 659 TE type(Tae-eumin)-subjects in multi-oriental hospitals and researched their ordinary symptoms. Subjects were diagnosed by the Sasang Constitutional specialists in oriental hospitals, and had remarkable improvement in the chief complains after Sasang Constitutional Medication. Subjects were divided two groups. One group had the Exterior-cold disease and they took the prescription for the Exerior-cold disease(such as Taeumjowi-tang, Jowiseungcheong-tang, Nocyongdaebo-tang etc.). The other group had the Interior-febrile disease and they took the prescription for the Interior-febrile disease(such as Galgunhaegui-tang, Yeoldahanso-tang, Cheongsimyeonja-tang, Gongjinhugwon-dan etc.). All subjects answered the questionnaire about their symptoms. We found the differences of answers using the Chi-square test between-group comparisons. We analyzed using SPSS 12.0 for Korean. 3. Results and Conclusions : In symptoms, Quantity of meal(p=.009), Perspiration of head and face(p=.001), Aspect of Excrement(p=.027), Presence of pain after excrement(p=.001), Frequency of urination at night(p=.003), Clarity of urine(p=.041), Sleep during the day(p=.049), Warm or cold feeling on abdomen(p=.007), etc. are different according to the Exterior- or Interior- disease. We found the differences of symptoms between not only the constitutional types but also the types of disease.

Song I-Yeong (1619 ~ 1692), who was an astronomy professor of Gwansanggam (觀象監, Bureau of Astronomy), created the Honcheonsigye (渾天時計, Armillary Clock) in 1669 (10th year of King Hyeonjong Era). Honcheonsigye was a unique astronomical clock which combined an armillary sphere, the traditional astronomical instrument of the Far East, with the power mechanism of western alarm clock. The clock part of this armillary clock is composed of two major parts which are the going-train, power unit used the weight, and the time signal system in a wooden case. The time signal system is composed of four parts which are the time-annunciator, the striking train, the 12 different time-announcing medallions and the sound bell. This clock has been neglected for many years and its several components have been lost. This study is to understand the structure of time signal system and suggests the restoration process.

1. Objectives This paper was written in order to understand formative process of Taeumin's Dry-febrile Symptom. 2. Methods We analysis Taeumin's Dry-febrile Symptom through pathology and prescription in ${\ulcorner}$Dongyisusebowonchobongyun${\lrcorner}$, ${\ulcorner}$Dongyisusebowongabo-bon${\lrcorner}$, ${\ulcorner}$Dongyisusebowonsinchukbon${\lrcorner}$. And we also analysis before study on pathology of Taeumin. 3. Results and Conclusions SCM was controled by Good-Qi. There was explained the strong and weak of Good-Qi to the number of real life. Slightness and Severeness of disease are dependent on the Health Energy of small viscera. So the interior febrile disease of Taeumin is divided to Liver-febrile symptom and Dry-febrile symptom. Because Liver-febrile symptom is reasonable symptom but Dry-febrile symptom is contrary symptom.

Since the thirteenth century, large scale facilities and various instruments for astronomical observation were built and installed in East Asia. During the Yuan Dynasty, S. ti.ntai (Beijing astronomical observatory in the Yuan Dynasty, 司天臺) was built in Beijing in 1279. Various astronomical instruments, including Ganui (Jianyi, simplified armillary sphere, 簡儀), Yang-yi (upward hemisphere, 仰儀) and Gyupyo (gnomon, 圭表) were installed in this observatory. These astronomical instruments were modified and improved by researchers of the Joseon Dynasty. Ganuidae (Joseon astronomical observatory, 簡儀臺) was built in Gyeongbokgung (or Gyeongbok palace, 景福宮), Seoul. Its scale was 31 Cheok (Korean feet in the Joseon Dynasty, 尺) in height, 47 Cheok in length and 32 Cheok in width. Lee, Cheon (李?, 1376~1451), a responsible leader of Ganuidae project, set up various astronomical instruments with his colleagues. Ganui and Jeongbangan (direction-determining board, 正方案) were installed at the top of this observatory. Gyupyo was installed at the west side of this observatory and Honui (armillary sphere, 渾儀) and Honsang (celestial globe, 渾象) were installed in a small pavilion which was located next to Gyupyo. A decade after installation, this observatory was moved to the north-west side of the palace but almost destroyed during Japanese invasion of Korea in 1592 except Ganuidae. We have analyzed documents about Ganuidae and investigated Chinese remains of astronomical observatories and artifacts of astronomical instruments. In this paper, we suggest the appearance, structure, arrangement and scale of Ganuidae, which are expected to be used for the restoration of Ganuidae at some day in the near future.

조선 천체위치측정기기의 구조 혁신 - 소간의, 일성정시의, 적도경위의를 중심으로 -

The Ganui (簡儀, simplified armillary sphere) is a representative of astronomical instruments in Joseon Dynasty of Korea, as well as Yuan Dynasty and Ming Dynasty of China. In early 15th century, Joseon's scientists and engineers uniquely developed the Soganui (小簡儀, small simplified armillary sphere) and the Ilseongjeongsiui (日星定時儀, sun-and-star time determining instrument) from the structural characteristic of Ganui. These two astronomical instruments had a new design by the miniaturization and felt convinced a similar performance of Ganui in the harmony with Korean Astronomy and Astrology Cultures. Since mid-18th century after the enforcement of shixian-li (時憲曆), the Soganui and Ilseongjeongsiui handed over the Jeokdogyeongwiui (赤道經緯儀, equatorial armilla) by a change of the observational framework such as the time and angle measures. The Jeokdogyeongwiui made by Gwansanggam (觀象監, Bureau of Astronomy in Joseon Dynasty) adopted the new observational framework. We studied the structural characteristics and scientific values of these 3 astronomical instruments with theirs observation methods.

Objectives For the methodological review on the accuracy study of questionnaire for Sasang constitution diagnosis, we searched the various diagnostic accuracy study of the questionnaires for Sasang constitution. Methods We searched MEDLINE, the Cochrane Library, KISS, and DBPIA. Additionally, We hand-searched the main oriental medical journals. All articles were independently reviewed and selected by two evaluators. And selected articles were assessed by "Quality Assessment of Diagnostic Accuracy Studies Tool"(QUADAS Tool) for the methodological review. Results The twenty eight studies initially identified studies were included in the methodological review. The part of "Acceptable reference standard", "Uninterpretable results reported" and "Withdrawals explained" was very weak in the risk of bias. The part of "Representative spectrum", "Acceptable delay between tests", "Incorporation avoided", "Reference standard results blinded", "Index test results blinded" was unclear in the description. Conclusions For the further study on the accuracy study of Sasang constitution diagnosis, we have to improve the aforementioned errors. Additionally, the checklist for the description of study might be needed.
