이 글은 새로 발굴한 필자 소장본 『여창가요록』을 소개, 고찰한 논문이다. 『여창가요록』 양승민본은 1853년도에 雲谷先生이라는 사람이 鶴仙娘子라는 京妓에게 필사해준 가집이다. 현전 『여창가요록』 중 最古本에 해당하는 이본이다. 늦어도 1853년 이전에 편찬되었기에, 『가곡원류』의 초창기 형성 과정을 보여주는 자료이다. 양승민본 『여창가요록』은 후대 『가곡원류』가 갖춘 기본적 체재를 두루 구비한 이본이다. 따라서 여창 중심으로 편찬된 책이긴 하나 『가곡원류』의 한 이본으로 평가할 수 있다. 적어도 박효관 주변에서 필사된 책이며, 박효관이 직접 엮고 필사한 책일 가능성도 높다. 편찬 시기가 늦어도 1853년이므로, 『가곡원류』와 같은 가집의 체재가 이미 19세기 전반기에 완성되었음을 알 수 있다. 또한 『여창가요록』은 이후의 집대성 완성본 『가곡원류』에서 별도로 파생된 것이 아니라 오히려 먼저 이루어졌다. 여창 중심의 기방 유행본 『가곡원류』가 이미 초기본의 형태로 존재했다. 이후 안민영과의 공동 작업으로 국악원본 『가곡원류』와 같은 증보 완성본이 편찬된 것으로 파악할 수 있다. 양승민본은 『가곡원류』의 형성 시기가 사실상 19세기 전반기임을 보여준다. 이 초기본의 발견으로 『가곡원류』의 형성기 모습 자체에 대한 연구가 구체적으로 가능해졌다. 『가 곡원류』라는 가집은 일시에 완성된 것이 아니라 19세기 가단의 움직임 속에서 다양하고 점진적인 형성 과정이 있었고, 여러 형태의 이본들이 당대의 시대적, 상황적 수요에 따라 유통되었다. This paper presents an introduction and examination of "Yeochanggayorok" of the Yang Seung-min version that had been newly excavated. The Yang Seung-min version of "Yeochanggayorok" was an anthology transcribed and provided by Master Woongok to a Gyeonggi gisaeng called Maiden Hakseon in 1853. It is an early version that is the oldest of the different remaining versions of "Yeochanggayorok." Since it was published before 1853 at the latest, it offers important materials to show the early formation process of "Gagokwonryu." First, the Yang Seung-min version of "Yeochanggayorok" is widely equipped with the formal framework of "Gagokwonryu" and accordingly another version of its in spite of the fact that it was published with a focus on Yeochang. Second, it is estimated that Park Hyo-gwan himself compiled and transcribed the Yang Seung-min version and published it in 1853. Such Yeochang-centric anthologies as the version must have been published before the completion of "Gagokwonryu" and in vogue around gisaengs`` saloons. Third, the version claims its worth as a material to advance the formation time of "Gagokwonryu" to the former half of the 19th century at the latest. The discovery of this early version of "Yeochanggayorok" made it possible to conduct concrete research on the aspects of "Gagokwonryu" themselves during its formation period. Finally, it is estimated that the anthology of "Gagokwonryu" was not completed at a time but went through various gradual formation processes in the middle of the movements of Gadan in the 19th century. As a matter of fact, there was no certain complete version of "Gagokwonryu"; instead, its versions of many different forms were widely distributed according to the demands of the times and situations those days.

The antioxidant properties of the extracts from torrefied wood subjected to superheated steam treatment were investigated. Total polyphenolics, total flavonoids, DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging activity, reducing power, and FRAP (Ferric reducing antioxidant power) were determined to evaluate antioxidant activity. The total polyphenol content was 879.67±40.41 ㎎/mL at a concentration of 25 g/mL when the extract was subjected to a temperature of 300℃ for 10 min, and 759.67±25.17 ㎎/mL at a concentration of 25 g/mL at 350℃ for 10 min. The value of at 300℃ was 15.79% higher than that obtained at 350℃. Total flavonoid content was 111.18±3.55 ㎎/mL at a concentration of 25 g/mL at 300℃ for 10 min, and 80.58±2.58 ㎎/mL at a concentration of 25 g/mL at 350℃ for 10 min. The value at 300℃ was 37.97% higher than that obtained at 350℃. For the DPPH free radical scavenging activity, the highest scavenging activity was observed at a concentration of 6 g/mL. DPPH free radical scavenging activity at a concentration of 6 g/mL at 300℃ for 10 min was 89.83±0.03%, whereas at 350℃ for 10 min at the same concentration, it was found to be 87.99±0.1%. The value at 300℃ was 2.09% higher than that obtained at 350℃. Reducing power was determined to be 3.59±0.04 at a concentration of 25 g/mL at 300℃ for 10 min, and 2.92±0.1 at a concentration of 25 g/mL at 350℃ for 10 min. The value at 300℃ was 22.94% higher than that obtained at 350℃. FRAP was 1742±37 μM at a concentration of 25 g/mL at 300℃ for 10 min, and 1106±8 μM at a at 350℃ for 10 min. At 300℃, the FRAP value was 57.50% higher than that obtained at 350℃. Based on these results, we suggest that torrefied wood treated with superheated steam can be used in various applications because of its effective antioxidant properties.

The purpose of this study is to evaluate the bioresorbability of Calcium Polyphosphate added with $Na_2O$ and chitosan. Though calcium phosphate ceramics meet some of the needs for bone replacement, they have some limitation of unresorbability and fibrous encapsulation without direct bone apposition during bone remodelling. To solve these problem, we developed a new ceramic, calcium polyphosphate(CPP), and report the biologic response to CPP in extraction sites of beagle dog. Porous CPP granules were prepared by condensation of anhydrous $Ca(H_2PO_4)_2$ to form non-crystalline $Ca(PO_3)_2$. CPP granules added with $Na_2O$ and chitosan were implanted in extraction sockets and histologic observation were performed at 12 weeks later. Histologic observation at 12 weeks revealed that CPP matrix were mingled with and directly apposed to new bone without any intervention of fibrous connective tissue. CPP granules added with chitosan were well adatped without any adverse tissue reaction and resorbed slowly and spontaneously. CPP granules added with $Na_2O$ and chitosan show multinucleated giant cells and osteoblast-like cells around grafted material and newly formed bone. This result revealed that CPP, regardless of its additive component, had a high affinity for bone and had been resorbed slowly. From this results, it was suggested that CPP is promising ceramic as a bone substitute and addition of $Na_2O$ and chitosan help biodegradation. In further study , it will be determined which concentration of $Na_2O$ help biodegradation and the other additive components increase the degradation rate.

Background: $TiUnite^{TM}$ is a highly crystalline and phosphate enriched titanium oxide surface which has a unique porous surface structure. This improved implant surface enhances bone response and reduces healing period. It also assures early stability of implant. These help to increase the success of implant. The aim of this study is to evaluate the survival rate of $TiUnite^{TM}$ surfaced single implant. Materials and methods: A retrospective analysis of 89 $TiUnite^{TM}$ surfaced implants replacing a single tooth was assessed according to their dental record. The age of the patients ranged from 17 to 82 years (mean age: $45.8{\pm}14.6)$. Data were recorded regarding the survival rate of these implants. Results: Fifty-two implants (57%) were placed in the maxilla, and 37 (43%) in the mandible. Over 75% were placed in the posterior area. Of the placed implants, 67% were the wide type. while 25% were the regular type and only 8% were of the narrow type. The single implants produced an overall clinical survival rate of 96.6% over the observation period (mean 17.9 months). Among 89 implants, only 2 implants were removed and one implant was submerged. Conclusion: According to these data, $TiUnite^{TM}$ surfaced implant in a single tooth restoration showed favorable survival rate although this study was done in a short term period.

지대주 풀림과 조임시 지대주 세척방법에 따른 임플란트 주변 골소실의 양에 대한 평가

양승민,신승윤,계승범,Yang, Seung-Min,Shin, Seung-Yun,Kye, Seung-Beom 대한치주과학회 2007 Journal of Periodontal & Implant Science Vol.37 No.3

Background : Repeated dis/re-connection of implant abutment caused bone loss around implant fixtures due to the new formation of biologic width of the mucosal-implant barrier. The aim of this clinical study was to evaluate whether the repeated dis/re-connection of implant abutment cause bone loss clinically and the effect of cleansing methods on a bone loss during the early healing period. Methods : A total 50 implants were installed in 20 patients and repeated dis/re-connection of abutment was performed at the time of surgery and once per week for 12 weeks. 0.9% normal saline solution as group1 and 0.1% chlorhexidine solution as group 2 was used to clean abutments. All patients had radiographs taken at the placement of implant and 4, 8, and 12 weeks postoperatively. The data for bone loss around implant were analyzed. Results: The marginal bone loss at 12 weeks were $1.28{\pm}0.51mm$, $1,32{\pm}0,57mm$ in the mesial and distal sides in group1, $1.94{\pm}0.75mm$, $1.81{\pm}0.84mm$ in group 2, respectively. In view of marginal bone loss, there was not a significant statistical difference between groups. Conclusions : Repeated dis/re-connection of implant abutment may not cause marginal bone loss around implant fixture although limited samples and short-term observation period. In spite of more bone loss in group 2, there was no statistical significant difference between groups. In context of those results, the clinical significance of the repeated dis/re-connection of implant abutment and the cleansing method of abutments is debatable when it comes to marginal bone loss during early healing period.

양승민,계승범,신승윤,Yang, Seung-Min,Kye, Seung-Beom,Shin, Seung-Yun 대한치주과학회 2008 Journal of Periodontal & Implant Science Vol.38 No.4

Purpose: The guided bone regeneration (GBR) technique is widely used in periradicular surgery. However, there is still some controversy regarding the effectiveness of GBR in promoting bone healing after periradicular surgery. The purpose of this study was to evaluate the resorbable membrane on the osteointegration of immediate implants in sites with periradicular lesion that had been removed by periradicular surgery. Materials and methods: Six roots of lower second premolars and 15 roots of lower third and fourth premolars of dogs were used as control and experimental teeth, respectively. Periradicular lesions were induced only in the experimental teeth. Twelve weeks later, the control and experimental teeth were extracted and implants were placed immediately. Periradicular lesions were removed with osteotomy, curettage and saline irrigation. Resorbable membranes were used in experimental group 1 but not in experimental group 2. After 12 week of healing period, the implants were clinically not mobile and showed no signs of infection. Data obtained by histomorphometric analysis were analyzed by Kruskal-Wallis test. Results: The control group showed a significantly higher bone to implant contact (BIC) ($74.14{\pm}16.18$) than experimental group 1 ($40.28{\pm}15.96$) and 2 ($48.70{\pm}17.75$)(p<0.05). However, there was no significant difference between experimental group 1 and 2. Conclusion: Although BIC in experimental groups were lower than in control group, immediate implant can be successfully placed at extraction socket with periradicular lesion and osseous defect. However, the use of resorbable membrane in bony defect created during periradicular surgery was questioned.

Purpose: The aerosol generated by ultrasonic scaler can contain bacteria or virus which can penetrate into body through respiratory systems of dentists, dental hygienist or patients. The aim of this study is to evaluate the effect of chlorhexidine digluconate as preoperative mouthrinse or lavage for ultrasonic scaler on the reduction of viable organisms in aerosol produced during periodontal treatment using ultrasonic scaler. Methods: 30 patients with moderate chronic periodontitis were included and divided into 3 groups: Control (no preoperative mouthrinse and tap water as lavage), CHG (preoperative mouthrinse with 0.1% chlorhexidine digluconate and tap water as lavage), CHL (no preoperative mouthrinse and 0.1% chlorhexidine digluconate as lavage). Each patient received scaling or subgingival curettage for 30 min. In CHG group, mouthrinse with chlorhexidine digluconate was performed for 1 min. before treatment. Before, during and after scaling or subgingival curettage, air sampling was performed for 7 min. each (1000 L/7 min.) with trypticase-soy agar plate. Agar plates were incubated in $37^{\circ}C$ aerobically. The numbers of colony-forming units (CFU) were counted and compared. Results: The numbers of CFUs of the samples obtained during treatment were $97{\pm}14.0$ in control, $73.1{\pm}14.9$ in CHG group and $44.5{\pm}9.0$ in CHL group. The difference among the 3 groups was determined to be statistically significant (one-way ANOVA with Bonferroni's correction, p-value: 0.0003). In contrast, the numbers of CFU of samples obtained before and after treatment were not significantly different among the groups. Conclusions: Chlorhexidine digluconate used as preoperative mouthrinse or lavage for ultrasonic scaler can reduce the microorganisms in aerosol produced during periodontal treatment using ultrasonic scaler. Less number of microorganisms were detected when chlorhexidine was used as lavage for ultrasonic scaler.

Although brain metastasis of renal cell carcinoma is a major cause of death in Von Hippel-Lindau disease(VHL), it is not easy to distinguish local recurrence of hemangioblastoma from distant metastasis. In addition, hemangioblastoma has several characteristics suitable for recipient of "tumor-to-tumor metastasis". Authors report a case of Von Hippel-Lindau disease that had metastases of renal cell carcinomas.
