To evaluate the effect of simultaneous use of platelet glycoprotein IIb / IIIa receptor blocker and catheter assisted thrombus aspiration in the treatment of coronary stent thrombosis. 267 patients ($64.6{\pm}12.1years$, 187 men) with stent thrombosis on coronary angiography at Chonnam National University Hospital from July 2008 to July 2017 were enrolled. We devided two groups based on treatment modalities: Group I (N=32, platelet glycoprotein IIb / IIIa receptor blocker and thrombo-aspiration), Group II (N =235, either platelet glycoprotein IIb /IIIa receptor blocker or thrombo-aspiration, or none of both), and the major cardiac events including death, revascularization and stent thrombosis were followed up for 1 year. There were no significant differences in clinical characteristics between the two groups including age (Group I: $60.8{\pm}12.9$ vs. Group II: $65.1{\pm}11.9$, p= 0.603), male (Group I: 75.0% vs. Group II: 69.4%, p=0.681), and left ventricular ejection fraction (Group I: $58.1{\pm}9.0%$ vs. Group II: $59.5{\pm}11.9%$, p= 0.127). The major cardiac events did not differ between the two groups (Group I: 12.5% vs. Group II: 23.8%, p=0.180). The secondary endopoints were as followings: The mortality rate (Group I: 0% vs. 13.2%, Group II: p=0.034), target lesion revascularization (Group I: 9.4% vs Group II: 6.4%, p=0.461) and stent thrombosis (Group I: 3.1% vs. Group II: 4.7%, p=1.000). In conclusion, in the treatment of coronary artery stent thrombosis, simultaneous use of platelet glycoprotein IIb / IIIa receptor blocker and thrombus aspiration was associated with better clinical outcomes regarding 1 year mortality.

The purpose of this study is to examine process and organization of local government-managed construction by reviewing official documents and materials in regard to the official residences and castles officially constructed in Dongnae in the 19c Chosun Dynasty. Results of this study can be described as follows. 1) The construction of official residences requires exchanges of official documents among upper and lower governmental agencies concerned. Previously prepared for some 1 or 2 months, the construction was proceeded through proceeded from Paok to Gaegi, Ipju, Sangryang, Gaeok and to Iptaek. Such construction was carried out independently and concurrently Gijang and Yangsan neighboring Dongnae provided cooperation by way of supplying labor and timbers. 2) Dongnaebu castle was constructed under local autonomy system, like other government-oriented works, as governor of Dongnae became responsible for defending such establishment in 1739. The castle was built up in 1731 as an establishment with 6 gated and 15 forts. Directly controlled by governor of Dongnae, the castle continued to be partially repaired until the 19th century. Under the regime of Daewongun, the castle was enlarged and extended for military strengthening. Besides the gate having double-gated structure for the outside wall, the other five gates came to have bastions and 30 forts were additionally established, dramatically changing the structure of the castle as whole. 3) Government-managed construction was often implemented by an organization whose members included local government officials, lower administrative agencies and local influential persons. The construction of official residences was implemented by Gamyeokdogam which was headed by Jwasu of Hyangcheong. In the construction, chief of military officials became supervisor, who was responsibly supported by Saekri. The construction of castled were divided into several works, for example, establishments of fortress, tower gate and quarrying stone were implemented by the organization of Paejang, Gamkwan and Saekri. As a military official, Gamkwan supervised the construction. Saekri was in charge of related internal affairs. Paejang was an technical expert leading several workers. The construction of castles in 1870 were organized as a general rule having particularity of social conditions on Dongnae.

Fish skin peptide-loaded liposomes were prepared in 100 mL and 1 L solution as lab scales, and 10 L solution as a prototype scale. The particle size and zeta potential were measured to determine the optimal conditions for the production of fish skin peptide-loaded liposome. The liposome was manufactured by the following conditions: (1) primary homogenization at 4,000 rpm, 8,000 rpm, and 12,000 rpm for 3 minutes; (2) secondary homogenization at 40 watt (W), 60 W, and 80 W for 3 minutes. From this experimental design, the optimal conditions of homogenization were selected as 4,000 rpm and 60 W. For the next step, fish peptides were prepared as the concentrations of 3, 6, and 12% at the optimum manufacturing conditions of liposome and stored at $4^{\circ}C$. Particle size, polydispersion index (pdI), and zeta potential of peptide-loaded liposome were measured for its stability. Particle size increased significantly as manufacture scale and peptide concentration increased, and decreased over storage time. The zeta potential results increased as storage time increased at 10 L scale. In addition, 12% peptide showed the formation of a sediment layer after 3 weeks, and 6% peptide was considered to be the most suitable for industrial application.

Most of the red ginseng (RG) products contain active substances derived from hot water or alcohol extraction. Since active substances of RG are divided into two types - water-soluble and liposoluble - water or alcohol is needed as an extraction solvent and this leads the different extraction yields and components of the active substances. To overcome the limit, whole red ginseng powder can be used and consumed by consumers. In this study, the physicochemical properties and extractable active substance contents of variable-sized RG powder ($158.00{\mu}m$, $8.45{\mu}m$, and $6.33{\mu}m$) were analyzed, and dispersion stability was measured to investigate the suitable size of RG powder for industrial processing. In the results, no significant difference was found from the changes in color intensity and thiobarbutric acid tests at $4^{\circ}C$, $25^{\circ}C$, and $40^{\circ}C$ for 4 weeks. There was no significant difference on the production of antioxidants and ginsenoside among the samples (p>0.05). In dispersion stability, $RG-158.00{\mu}m$ was precipitated immediately, and the dispersion stabilities between $RG-8.45{\mu}m$ and $RG-6.33{\mu}m$ showed no significant difference. It implies that fine RG is suitable for the production process. With further study, it seemed that the physicochemical effects of RG particle sizes can be clearly revealed.

Background: Many studies have reported that adolescents living with single parent have a high risk of obesity. However, those studies did not explore the implication of the gender of single parent living with adolescents. This study investigated the differences in obesity rates according to status of co-residence with their parents in Korean adolescents. The family living with single parent was classified into the family living with single father and the family living with single mother. Methods: This cross-sectional study involved 59,602 adolescents who participated in the 2017 Korea Youth Risk Behavior Web-based Survey. The data on height, weight, status of co-residence with parents, and the other variables were obtained through online questionnaires. Results: In male adolescents, the family living with single mother was related to a high proportion of obesity (odds ratio [OR] 1.24, 95% confidence interval [CI] 1.09-1.40) and overweight (OR 1.17, 95% CI 1.03-1.34). However, in female adolescents, the family living with single father was related to a high proportion of obesity (OR 1.49, 95% CI 1.23-1.82). In addition, female adolescents living with neither parent were more likely to be obese (OR 1.47, 95% CI 1.13-1.91) and overweight (OR 1.31, 95% CI 1.00-1.70). Conclusions: This study showed a risk of obesity in adolescents living with single parent differs according to the gender of single parent living with adolescents. Not adolescents living with a same-gender parent, but those living with an opposite-gender parent have a high risk of obesity.

Various decipherment technologies, including manual rubbing, have been continuously applied to the Goguryeo Stele in Chungju. However, an official document for advanced decipherment is required as there remain characters to be deciphered. This study focuses on interdisciplinary digital decipherment using digital visualization results based on reflectance transformation imaging and three-dimensional scanning. On that basis, the joint decipherment document in 2019 is classified into eight types according to character changes from 1979 to 2000, and decipherment achievements are discussed. Important outcomes of the joint decipherment document include a new interpretation of four existing characters and the identification of 28 new characters. Additionally, 68 characters on the front face and 20 on the left face, which are listed differently in previous decipherment documents, are determined to be a single character through a consensus process. Compared to the previous decipherment document, the "decision" character is increased by a total of 89 characters (22.6%), and the "different opinion" character is decreased by 126 characters (32.0%). Thus, this digital decipherment greatly contributes to the reexamination of the Goguryeo Stele in Chungju and complements the previous decipherment document through reflectance transformation imaging and three-dimensional scanning. However, continuous research is necessary to enhance decipherment rates, since 123 characters (31.3%) are yet to receive decipherment. In the future, decipherment advancement regarding the Goguryeo Stele in Chungju should be based on convergence research between the humanities and science. Furthermore, it seems that researchers must make constant efforts to apply new imaging analysis technology and to develop customized technology for decipherment.

The purpose of the study was to understand the symbol and locational meanings in building and relocating Gwangje-jeong(光霽亭) through the analysis and interpretation on the construction background, history, the location and its characteristics. Concerning physical environment, human activities, the symbol and meanings of the formal Gwangje-jeong site and the present location, the study was concluded about the site and its meaning of tradition as following. Gwangje, the name of the pavilion, represents the fidelity of Maedang(梅堂) Yangdon(楊墩) who refused as Seonbee(a man of virtue) to be tainted with the corrupt world, which was related with the situation at that time. It implies Maedang's feeling of realizing Noojeongjeyong(樓亭題詠) of Gwangje-jeong along with the high spirit of Gwangpoongjewol(光風霽月). According to the record about rebuilding Gwangje-jeong, Maedang was the very person who planted plum flowers at the pavilion and put up the tablet of its name, Gwangje. Even after his death, Gwangje-jeong was the symbol indicating Yangdon, given the triple high ground and the planting of plum flowers. Also, Sookho(宿虎) town at the entrance of Gwangje-jeong and Bokhoam(伏虎巖: a rock) at the right side of the pavilion signifies the location for praising Maedang Yangdon, and the Yangjipha's Oensi(五言詩: five words verse) engraved on the rock gives a good description about the place, Agyesa that worshiped Yangdon. As Agye-Sa(阿溪祠) where Yangdon was worshiped and praised had been abolished in the 5th year under the Kojong's reign(1868), the spirit praising Maedang had finally been used for the relocation of Gwangje-jeong. Despite the relocation of Gwangje-jeong, the old Gwangje-jeong site has remained at least for 359years at Hucheonli, and its surroundings have maintained the name 'Gwangje' as the front place name morpheme, for example, 'Gwangje-jeong,' 'Gwangje Town,' 'Gwangje Bridge' and 'Gwangje Creek,' for symbolizing the praising of Maedang. Gwangje-jeong, as the center place of solidarity among Namwon Yang's family clan, has been able to maintain its symbol and meanings in spite of relocation, mainly because of the fellowship among the descendants, family clan and alumni who respected virtuous achievements of ancestors and shared the agony of the time. In addition, the symbolism has been preserved since the spirit of Gwangpoonjewol of Yangdon and his high character were cherished along with the spirit of Bongseon(奉先) that inherited and kept virtuous achievements of ancestors.

This study is aiming to acquire data for enhancing genuineness of restoration through reviewing external and internal scenery of Baegun-dong Wonlim such as Baegun-dong 8 Objects of Scenery(pines, bamboos, chrysanthemum, orchid, maehwa blossom, magnolia, fiddle and crane) and 12 Scenic Spots and reviewing internal and external scenery of Baegun-dong Wonlim such as views and scenery for plantation. For Baegun-dong 8 Young which sang songs about scenic spots of Baegun-dong Wonlim it seemed that its head words were formed through borrowing rhyming words from caption of Baegun-dong Yuseogi(白雲洞幽棲記). Accordingly it seemed these scenery secured its status of Wonlim from the beginning. Particularly the words of fiddle and crane in 琴棋書畵(Geumgisuhha) implied that playing Komungo and brushwriting were firmly rooted as romantic pursuits of classical scholars of that time. In consideration of distance upto Okpanbong which is one of 12 scenic spots of Baegun-dong radius of outer circumference is estimated to be around 1.6km. From Okgpanbong, the epicenter, Sandagyeong, Baegokmae, Hongokpok and Pungdan etc. correspond to transitional space. And inner scenery was formed with hub of thatched cottages and bowers surrounded with chrysanthemums, poenies, rhododendron, Phyllostachys bambusoides, pines and upper and lower water paths. Thus it seemed there was scenic structure of centrifugal nature as well as of multiplicity. Forms of majority of water paths with residual structure found in the country have streamlined forms on the other hand Baegun-dong water paths have straight line which almost dominate inner gardens in terms of scale and forms thus revealing its extraordinary idea and design. In order to promote genuine restoration of Baegun-dong Wonlim it will be necessary to have consideration from standpoint of managing perspective to assure presentation of gradual scenery with elements of scenic objects for outer view among 12 Scenic Spots.
