King Hyeonjong, the 18th king of the Chosun Dynasty, reigned for 15 years. During his reign, he underwent a political incident named the Controversy about the Confucian Funerary Rituals. This incident was carried out 2 times: 1 time during early days of his reign and 1 time during later days. Although it started out as a trivial dispute over the period Queen Dowager Ja-eui(stepmother of King Hyojong, Hyeonjong's father) had to wear a mourning dress, it advanced to a political incident concerning the acknowledgement of King Hyeonjong's legitimacy and political pride of the king and the vassals. Although existing researches focus on the historical context of this incident, this study focuses on the relationship between this incident and King Hyeonjong's disorders. During the First Controversy about the Confucian Funerary Rituals, King Hyeonjong was treated for various symptoms concerning hypochondria. During the Second Controversy, he suffered from septicemia as well as diabetic complications. This study is based on the texts of "The Daily Records of Royal Secretariat of Chosun Dynasty".

Through articles published in the Seungjeongwon Ilgi, the following conclusions were obtained by analyzing how King Hyeonjong used Five-Transport-points. For the use of Five-Transport-points for King Hyeonjong, Five-Transport-points of most meridians was evenly used, except that no Five-Transport-points of Kidney Meridian were used. The use of Five-Transport-points for King Hyeonjong were evenly used for Jung acupoint, Shu acupoint, Hap acupoint. Among them, the use of Jung acupoint was remarkable. The diseases that were most frequently treated by using of Five-Transport-points for King Hyeonjong are ophthalmology, fever, and common cold. The Five-Transport-points were used most for feverish diseases. When performing the procedure using Five-Transport-points for King Hyeonjong, acupuncture and moxibustion were widely used at 95.7:4.3. It can be seen that this is due to the location of Five-Transport-points.

Objectives : This study is on the acupuncture and moxibustion treatment records of King Hyeonjong, classified according to diseases and chronology. Methods : Records on the acupuncture and moxibustion treatment of King Hyeonjong have been extracted from the web database of "The Daily Records of Royal Secretariat of Chosun Dynasty". First, all articles containing the keywords 'Yakbang (藥房)' and 'Euigwan (醫官)' have been extracted. Then, those during King Hyeonjong's reign have been rearranged in chronological order. Among these records, those regarding acupuncture and moxibustion have been used in this paper. Results : King Hyeonjong was mostly treated on eye diseases, musculoskeletal system disorders, deficient source qi, and tumor. Acupuncture treatment was preferred for eye diseases, and moxibustion treatment for musculoskeletal disorders. Medicine was used 50 times, acupuncture 4 times, and moxibustion 14 times to treat source qi deficiency, showing that acupuncture and moxibustion treatments were used for clear deficiency syndrome. Only on the case of tumor, the number of acupuncture treatments was bigger than that of medicine treatments. Conclusions : In the early days of his reign, King Hyeonjong suffered from hypochondria, as compared to source qi deficiency and septicemia during later days. He received frequent acupuncture and moxibustion treatments, and he especially preferred those treatments for eye diseases and musculoskeletal disorders.

We investigated the records of astronomical phenomena in the Hyeonjong-Donggung-Ilgi written by the educational office for a crown prince, Sigang-won, during the time of a crown prince of the king Hyeonjong (i.e., from 1649 to 1659). Of the total of 3,625 days, 3,044 astronomical accounts were compiled from astronomical records of 2,003 days. We classified these astronomical accounts into 16 items, grouped into five categories, and statistically analyzed each group. In our analysis, the accounts for atmos-pheric optical phenomena equates to 57.9% of the total, and for celestial phenomena visible during the daytime the percentage is 17.3%. The records related to the approach between two objects such as planets, moon, and stars account for 3.3%, and solar or lunar eclipses take up 0.6%. The ratio of accounts regarding meteor, comet, and fire light (火光) stand at 13.8%, 0.30%, and 6.8%, respectively. Sunny days account for 71.1% of all days per year during this period. We determined that the distribution of the fire light by month is similar to that of the solar halo. We also found that the astronomical records from the Annals of the Joseon Dynasty correspond to only 30% of those of the Hyeonjong-Donggung-Ilgi for the same period. In particular, the phenomena of celestial objects occurring outside the atmosphere are transmitted to the Annals of the Joseon Dynasty in a higher proportion than the phenomena inside the air. It is therefore necessary to use a historical diary like a Donggung-Ilgi to interpret the phenomena in the air such as atmospheric optical events, meteor, and fire light.

Objectives : The aim of this study was to examine the effects of electro-acupuncture(EA) at the SP6(Sameumgyo)-GB39(Hyeonjong) on normal human EEG using power spectral analysis. Methods : EEG power spectrum exhibit site-specific and state-related differences in specific frequency bands. In this study, power spectrum was used as a measure of complexity(LAXTHA Co., KOREA). 30 channel EEG study was carried out in 20 subjects $(20\;males;\;age=21.4{\pm}0.5\;years)$. Results : In $\alpha$(alpha) band, the power values at F4 channels(p<0.05) during the SP6-GB39 acupoints treatment was significantly increased. But, the power values at Fz channel during the non-acupoint treatment was significantly decreased . In $\beta$(beta) band, the power values at Fz, FTC1, T3 channels(p<0.05) was significantly increased during the SP6-GB39 acupoints treatment. In $\delta$(delta) band, the power values at F4, C3, Cz, CP1, Pz channels(p<0.05) during SP6-GB39 acupoints treatment were significantly decreased.

1. King Hyeonjong(1641-1674) mainly suffered from eye disease and abscess. He specially took a hot spring bath for cure of eye and skin problems. He probably died of septicemia and the following gastro-intestinal infection at the age of 34, quite early for his age. 2. King Sukjong(1661-1720) was not very well all through his life, but lived quite longer than other Kings in the Joseon Dynasty. He suffered from various diseases like heart-based heat, abscess, edema, upper respiratory infections, etc. He frequently took the treatments of acupuncture and moxibustion. He presumably died of dysfunction of liver and kidney at the age of 60. 3. King Gyeongjong(1688-1724) suffered from political problems from birth to death, so he may have had excessive mental stress for his poor health. He mainly suffered from heart-based heat and abscess. It is quite not sure why he died in only one month from the onset of his symptoms, so many people thought that he was poisoned to death. He probably died of septicemia and the following gastro-intestinal infection at the age of 37. 4. King Yeongjo(1694-1776) lived for 83 years, which is the longest of all the Kings in the Joseon Dynasty. He mainly suffered from hypofunction of gastro-intestinal system with cold symptoms, coughs, uneasiness. He took various kinds of herbal medicine, of which he took ginseng the most. He is supposed to be dead due to his old age at 83.

Queen Myeongseong was the wife of King Hyeonjong, the 18th king of the Joseon Dynasty, and the mother of King Sukjong. The clinical records of Queen Myeongseong are summarized on the basis of the Seungjeongwon Ilgi (The Daily Records of Royal Secretariat of Joseon Dynasty 承政院日記) and reviewed through Donguibogam. Queen Myeongseong gave birth to one male and three female children in the time of the queen. She took Geumgaedangguihwan (金櫃當歸丸), Dalsaengsan (達生散), Antaeum (安胎飮) during her pregnancy and Gungguitang (芎歸湯) during postnatal care. Since 1669, chest tightness, sleeplessness, arm pain and numbness of arms had been appeared. Ondamtang (溫膽湯) and Dodamtang (導痰湯) were used but they were not effective. However, when her symptoms were regarded as a benign tumor due to cold and wetness, there was a difference in the use of Ohjuksan (五積散). In 1683, when king Sukjong was caught in a smallpox, she took care of him. She exorcised in the middle of winter to pray for her son's recovery, and died of the flu.

A new putative laccase gene (soncotA) which show 78% homology with that from Bacillus licheniformis (liccotA) was isolated from draft genome sequence of Bacillus sonorensis KCTC 13918. A 1,545 bp of PCR product corresponding 514 amino acids was cloned into NdeI-NotI site of pET21c and expressed as soluble form in E. coli. About 59 kDa size of recombinant laccase was purified into homogenity by Ni-NTA column and laccase activity was confirmed by zymography. The enzymatic properties of recombinant laccase were characterized. The specific activity of B. sonorensis laccase was 0.033 fold lower than that of Bacillus licheniformis laccase. The finding of new laccase gene broadened the enzymatic diversity of Bacillus species laccases.

Fabricating a surveyed prosthesis beneath an existing partial removable dental prosthesis (PRDP) is a challenging and time-consuming procedure. The computer-aided design/computer-assisted manufacturing (CAD/CAM) technology was applied to fabricate a retrofitted, surveyed zirconia prosthesis to an existing PRDP. CAD/CAM technology enabled precise and easy replication of the contour of the planned surveyed crown on the existing abutment tooth. This technology ensured excellent adaptation and fit of newly fabricated crown to the existing PRDP with minimal adjustments. In this case report, a seventy-year-old male patient presented with fractured existing surveyed crown. Because the existing PRDP was serviceable, new crown was fabricated to the existing PRDP.

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.
