This study is on dancing dresses of the costumes of Gum-Mu(劍舞, sword dance) in southern, central, and northern region of Korea, focusing on the origin, characteristics and the way of dance. The reason why the Gum-Mu is full of local color is that royal Korean Gisaeng(妓生) and local Gisaeng returned to their hometown and propagated this dance to each regional Kyobang. They combined court sword with each local dance and music and formed the present style of regional Gum-Mu. Dance and music native to area, which has formed today's regional Gum-Mu. The composition of current dancing costume of the sword dance is Jeogori, Chima, Jeondae(戰帶), Jeonrib(戰笠), Kwaeja(快子) Also, The complement colors harmonizing with color of Yin-Yang & Five Elements. which are yellow, blue, white, red, and black, are usually used. And the masculinity in dance were expressed withmore use of blue, and red in the opposite but if a sword dance takes on masculine character, blue color is more used, if feminie character, reddish colors, such as pink and red, are used. Thus, JinJu, Honam, Haeju, Pyeongyang dancing Suit of Gum-Mu feature blue color, Tongyeong, Kyeonggi, Court(seoul)dancing Suit of Gum-Mu feature reddish color.

The rainfall amount data measured by 'Wootaek', a method of measuring how far the moisture had absorbed into the soil when it rains during the Joseon Dynasty, were estimated with the Chugugi data in the 12 sites where both the 'Wootaek' and 'Chugugi' data are available. Excluding the 5 sites (Ganghwa, Jinju, Jeonju, Chuncheon, Hamheung) poor in sample data, the 'Wootaek' data 1 'Ri' and 1 'Seo' in 'Chugugi' unit (Bun) in the 7 sites; Suwon, Gwangju (Gyeonggi-do), Gongju, Daegu, Wonju, Haeju and Pyeongyang, were 11.1/5.6 Bun, 9.4/3.2 Bun, 14.0/5.7 Bun, 9.3/3.9 Bun, 13.6/4.3 Bun, 11.3/4.8 Bun and 16.8/7.4 Bun, respectively. The Chugugi unit 1 'Bun' is equall to approximately 2 'mm'. The average of the 7 sites is 13.1/5.7 Bun, however it becomes small to 11.7/4.5 Bun when the Pyeongyang of which data is considerably distributed over wide range is excluded, showing that the 'Wootaek' data 1 'Ri' is approximately the 2.3~2.6 times of 1 'Seo'. It is recommended to use the individual estimates of the sites in utilizing the 'Wootaek' rainfall data of 352 stations across the country restored from the "Gaksa-deungnok".

Background: This study was conducted to evaluate the hemodynamic performance and the incidence of prosthesis-patient mismatch (PPM) after aortic valve replacement (AVR) using bovine pericardial valves (Carpentier-Edwards Perimount Magana and Magna Ease). Methods: In total, 216 patients (mean age, 70.0±10.5 years) who underwent AVR using stented bovine pericardial valves and had follow-up echocardiography between 3 months and 2 years (mean, 12.0±6.6 months) after surgery were enrolled. The implanted valve sizes were 19, 21, 23, and 25 mm in 32, 56, 99, and 29 patients, respectively. Results: On follow-up echocardiography, the mean transvalvular pressure gradients for the 19-mm, 21-mm, 23-mm, and 25-mm valves were 13.3±4.4, 12.6±4.2, 10.5±3.9, and 10.2±3.7 mm Hg, respectively. The effective orifice area (EOA) was 1.25±0.26, 1.54±0.31, 1.81±0.41, and 1.87±0.33 ㎠, respectively. These values were smaller than those suggested by the manufacturer for the corresponding sizes. No patients had PPM, when based on the reference EOA. However, moderate (EOA index ≤0.85 ㎠/㎡) and severe (EOA index ≤0.65 ㎠/㎡) PPM was present in 56 patients (11.8%) and 9 patients (1.9%), respectively, when using the measured values. Conclusion: Carpentier-Edwards Perimount Magna and Magna Ease bovine pericardial valves showed satisfactory hemodynamic performance with low rates of PPM, although the reference EOA could overestimate the true EOA for individual patients.

In this study, drought of North Korea are analyzed using drought index. 27 weather stations are selected and monthly precipitation and average temperature data are collected for drought analysis. SC-PDSI is used for drought analysis and calculated using collected weather data during 1984~2013 (30 years) in 27 weather stations. From the analysis result of historical drought event using drought index, it is confirmed that severe droughts occurred in the early and mid 2000's at most stations. Secondly, drought frequency analysis was carried out for the derivation of drought severity-duration-frequency (SDF) curves to enable quantitative evaluations of past historical droughts having been occurred in 6 stations (Pyeongyang, Hamheung, Cheongjin, Wonsan, Haeju, Sinuiju). This study can suggest return periods for historical major drought events by using derived SDF curves for each station. In the result, drought events in the early and mid 2000's had return periods of 20~50 years.

The heading responses of rice varieties that originated from South Korea, North Korea, and northern China were examined under the temperature and day-length conditions of 13 major rice production areas in North Korea. Kenjiandao3 and Nongdae3 originated from China, Olbyeo1, Olbyeo2 and Sonbong9 from North Korea, and Joun from South Korea demonstrated the earliest heading stage depending on the regional environment. Out of 40 rice varieties, 34 reached the heading stage within the regional safe marginal heading date (SMHD) under Haeju and Sariwon environmental conditions, while 16 to 17 varieties reached the heading stage under Wonsan, Changjon, Supung, and Yongyon environmental conditions. Some middle and mid-late maturing varieties that originated from South Korea reached the heading stage within the SMHD under the temperature and day-length conditions of Kaesong, Haeju, Sariwon, Nampo, and Pyongyang that are located in the west-southern plain. The majority of early maturing varieties, but not the middle or mid-late ones, reached the heading stage within the SMHD under the environmental conditions of Singye, Anju, Kusong, and Sinuiju. Only a few early maturing varieties demonstrated the heading stage within the SMHD under Yongyon, Changjon, and Wonsan environments. The number of days to heading was highly positively correlated among all regions; however, it was not consistent among the rice varieties. The 40 rice varieties that had been tested were classified into seven groups according to their heading responses to the temperature and day-length variations of the 13 regional conditions at 65% similarity level in cluster analysis.

The purpose of the current study was to identify expectations regarding aging and health-promoting behaviors and to examine whether expectation regarding aging was associated with health-promoting behaviors among community-residing Korean adults. Data were collected from 233 adults dwelling in the community of Daegu and Kyungpook province. The influence of expectations regarding on health-promoting behaviors was analyzed through hierarchical multiple regression controlling for sociodemographic variables. As a result, the mean score of expectations regarding aging was significantly lower in 40s and 50s than 20s and 30s. The participants had the lowest expectations regarding aging in terms of physical health domain and the highest expectations in terms of mental health domain. No significant differences were found in health-promoting behaviors among different age groups. After controlling for sociodemographic variables, expectations regarding aging were independently associated with health-promoting behaviors in adults in 20s~30s but not in those in 40s~50s. The findings suggest the need for encouraging Korean adults to strive for having positive and active perspective on aging and for getting higher expectations regarding aging, in particular, for 20s and 30s, as a health-promoting strategy.

In Korea, aside from their official administrative names, aliases of each province or some regions are widely used not only today but also during the Joseon period when the provincial system as local administrative system was firmly implemented. Of aliases, the most representative were Giho, Gwandong, Hoseo, Haeseo, Honam, Yaeongnam, Gwanseo, and Gwanbuk representing the eight provinces (precisely, Gyeonggi and seven provinces) of Chosun Dynasty, as well as Yeongdong and Yeongseo that represent the east and the west of Gangwon-do. These aliases are mostly based on topographical features and physiographical elements, and compared to the official names of eight provinces which depended solely on city names. Of aliases, some appeared in literature during 13-l4th centuries, and all provincial aliases seem to have been widely used after the late 15th century. Aliases continued to be used for 500 to over 700 years. Aliases of eight provinces, geographically, played not lesser role than their official names. Aliases of the eight provinces and regions during the Chosun Dynasty that have been handed down are considered as holding their places' cultural and historical backgrounds, and have become important enough to be accepted as a unit of geographical regional division. The origin and meaning of aliases of each province have been partially disclosed to the geographical circle and the general public. However, the details should be reviewed. First of all, Gwan in Gwanbuk, Gwanseo and Gwandong, as well as Yeong in Yeongnam, Yeongdong and Yeongseo, are each considered as meaning Sobaek Mountain Range and Taebaek Mountain Range with many borderline areas (borders) and military strategic hubs. Also, Ho in Honam, Hoseo, and Giho, are considered as based on the Geum River and Eurimji, and Haeseo are considered as meaning the west of the Gyeonggi Bay, and having relevancy with the first letters of Haeju and Seoha (Pungcheon).

Smart cities are expanding their spatial scope to urban areas and regions. Linking regional economic development strategies beyond the borders with smart city planning can lead to cooperation and economic development between regions and countries as well. The purpose of this study is to suggest cooperation and regional development of the three nations - Korea, North Korea and China - through the Yellow Sea Rim Smart Region. To this end, smart city strategies and economic development plan with implementation status in the three countries including special economic zones have analyzed that could be the spatial basis of the smart region. On the west coast of Korea facing the Yellow Sea, lots of projects related to smart cities are actively underway in Saemangeum, Yellow Sea Free Economic Zone(YESFEZ), and Incheon Free Economic Zone(IFEZ). Although the political situation is still uncertain, North Korea is analyzed to have economic and technical potential in the west coast connecting Haeju, Nampo, and Sinuiju. In Liaoning and Shandong provinces of China, smart city projects have been actively promoted in recent years especially in the state-supporting industrial cities. Restoration of economic cooperation between South Korea and China, linkage of transportation networks, vitalization of cross-border cooperation projects between China and North Korea centered on Dandong and Sinuiju, and the connecting of smart city infrastructure and services for China and South Korea's economic cooperation process will make the Yellow Sea Rim as a world prosperous economic region. However, it is necessary to establish and operate a governance system through long-term planning for transnational consultation and establishment of a promotion organization.

Monitoring technology based on electrical resistivity is widely used for non-destructive data collection and health analysis of underground structures and tunnels. Vulnerable sections such as fault zone generates many problems during construction of the tunnel. These problems cause displacement and stress changes of the ground. Therefore, it is necessary to predict the state of the fault zone section to ensure the mechanical stability of the underground structure. Monitoring the size of joints and the porosity of the fillings is essential for rocks. Previous studies have not considered the variety of fillings in rock joints. In this study, electrical resistivity tests were conducted according to the particle mixing state of the sandy fillings. When the size of fillings is decreased at the constant porosity, the electrical resistivity tends to increase. The results of this study are expected to be useful as basic electrical resistivity data for predicting the ground conditions and evaluation of the ground behavior that is containing sandy fillings in the rock joint for tunnels.
