This study was conducted to serve as a basis for education by identifying the correlation of college admission type, college-life satisfaction and academic achievement of radiologic science students. Data were collected from 2 universities and 2 colleges located in Gyeonggi Provice, North Chungcheong Province, North Gyeongsang Province. A total of 371 questionnaires were collected, 363 of which were included in this study. The results showed that there were no differences in academic achievement according to the type of college admission. It could be able to interpret that since department of radiologic science is popular, students with high academic records applies the department of radiologic science and there are less deviation of academic records among students. A correlation analysis of academic achievement showed learning attitude is a statistically valid factor. Learning attitudes can be changed by exposure to the environment. This will require a variety of program development for improving learning attitudes. In addition, academic achievement of radiologic science students is associated with license acquisition. It need to be made together research on determinants and development of learning method to improve the learning attitude.

The studies of Korean traditional gardens have been a lot of diachronic approaches through ancient documents and on-site investigation. Previous research has focused on the characteristics that are inherent symbolism of the traditional landscape space, such as site characteristics. There are many studies for inner gardens, outer gardens and other influential ranges of gardens of the location characteristics. However, studies on the scale of external gardens were not satisfactory from a quantitative perspective. Unlike private life sphere, quantitative analysis was conducted on the role of a sphere of public community life for outer gardens. Visibility analysis was performed through the existing literature and GIS programs to estimate the magnitude of the outer garden. When it was compared with Min G. H.(1982) research, it is almost the same if it is estimated to focus on Buyoung -bong(芙蓉峯) and Ip-am(立巖). Also, as a result of the fractal structure for a variety of symbols in the garden, fractal dimension in landscape elements is relatively concentrated, unlike in other areas. Thus, the external scale can be a means of cultural property protection out of the crucial perspective for the inner garden. There has been consideration of the cooperation with the visual complexity using the concept of fractal structure as one of the elements of landscape analysis.

진하 해수욕장은 부산에서 약 40km 정도 동해안도로를 거슬러 올라가면 경남 울주군 진하리에 위치한 조그마한 자연해변의 해수욕장이다. 해수욕장의 동쪽에서는 회야천이 흘러 들어오고, 이 하천의 3km 상류지점에는 댐을 축조하여 온산공단 및 주변지역의 생활용수를 공급하고 있다. 어울려서, 쾌적한 위락시설 단지로서는 최적이라고 생각된다. 현재 이 해안은 매년 침식이 진행되면서 해수욕을 할 수 있는 해변 공간이 줄어들고 있는 실정이다. 따라서 이 해안을 보전하기 위해서 관청과 주민들은 많은 심혈을 기울이고 있는 실정이다. 본 연구의 조사단은 1987년부터 해마다 수침측량을 실시하여 해수욕장의 지형변화를 조사하고 있다. 특히 이 해수욕장의 사빈은 몇년전 부터, 침식형의 사빈으로 변화되어 매년 많은 모래가 유실되는 현상이 발생하고 있어, 관청 및 주민들의 관심을 집중시키고 있다. 따라서, 금년에도 울주군청에서는 회야강 하구에 생성된 사주를 준설하여 준설된 모래를 해수욕장에 인공적으로 투입하여 양빈을 실시하고 있는 실정이다. 이 작업은 하구폐색의 문제를 해결할 뿐만 아니라 선박의 운행에도 큰 도움을 주고 있다. 이러한 작업은 기초해안 자료를 충분히 검토된 상태에서 실시되어야 한다. 그러치 못할 경우는 인위적으로 투입된 모래는 파랑에 의해서 다시 심해방향이나, 해안류를 따라서 다시 하구로 밀려오는 현상이 일어 날 것이다. 본 연구는 회야강 하구의 지형변화와 진하 해수욕장의 사빈의 변화를 정확히 파악하고져 단기간 동안 심천 측량을 실시한 결과를 이용하여 기존이론으로 해석한 결과를 제시함을 목적으로 한다.고 동시에 광 스트레스에 대한 저해를 감소시키는 것으로 보인다. 있다. 청주권의 무심천도 계획상은 대청댐의 물을 공급 받을수도 있도록 되어 있으나 현실상으로 상수도 원수로서의 공급마저도 매년 심한 원수 수질 문제(5-6월, 10월경의 취수장 부근의 부영양화 현상으로 인한 악취와 물 맛의 문제)를 1984년부터 겪고 있다. 이와 같이 도시권 하천의 수자원은 자연적, 인위적, 경제적, 법적, 제도적 여러 제한 요소로서 특성을 가지고 있으며 이는 날로 심해 가고 있는 실정이다. 그러므로 최적 물관리 시스템의 개발이 새로이 시작하는 수자원 개발 사업에서는 계획 단계에서부터 절실히 요구되는 바이며 기존 시설물의 관리 운영은 과감히 그 운영 관리 기준을 보완 재 정비하여야 할 것이다. 지금까지 대부분의 수자원 종합 개발 계획이 홍수방이나 용수 공급 및 수력 개발 등에 주력하여 왔으나 이제는 보다 더 수자원의 환경 보전적 차원과 도시의 안정적 발달을 위한 지역 및 권역 계획과 연계지워져서 양적인 안정 공급과 더불어 질적인 향상과 연계지워서 경제-사회적 요구에 부응할 수 있도록 도시권의 수자원을 최적 관리할 수 있는 방안을 강구하여야 할 것이다. 이는 각 도시 하천의 수자원의 정량적·정성적인 특성 및 제한 요소를 충분히 감안하여 수요-공급 개념에 의하여 과감히 기존 시설(예: 팔당댐의 운영, 대청댐의 운영 등)의 관리 운영 체계를 개선하여 나가야 할 것이며, 수질 보전적-환경 보전 차원에서 저수관리 체계를 확고히 할 수 있는 방안을 강구하여야 할 것이다.펄스주입법에 의해 증착된 박박은 강유전성 이력을 나타내었다.지역

In this study, we investigated the stone materials used in the Woldae of Kwanghwamun gate to estimate their provenances. The Woldae was partly reconstructed in 2010 using red-colored original stone and greyish new stone. We carried out geological survey in Mt. Bukhan (Bukhansan) and Mt. Surak (Suraksan) to estimate the source of stone, where red-colored granitic rocks are widely distributed. Though the petrographical features of the granitic rocks from the surveyed area are quite similar, there exists a slight variation of magnetic susceptibility and color index of the rocks: the granitic rocks from Mt. Surak have higher value of magnetic susceptibility and clearer reddish feature. A series of evidence, such as historical records, stone cutting traces and petrographical features, for the source of stone materials used in the Woldae tells that Mt. Surak would have been the provenance for the stone materials used in the Woldae. We also conducted a nondestructive test to examine the physical property of the rocks. The original stone shows low compressive strength (147 MPa) due to the weathering, whereas the rock in Mt. Surak has higher compressive strength (244 MPa) capable of being used as building materials. If there were any difficulties to use the granitic rocks in Mt. Surak, some granitic rocks that have similar petrological characteristics, such as Changsu stone and Yeongjung stone from the Pocheon area, could be used as building material instead.

Sports wear in relation to sports life is being developed in fashion industry with increasing leisure time. However, design development for swimwear including trend analysis is still required. In this research, we analyzed design trends in domestic social and cultural environment, and fashion design elements for the development for swimwear. We collected 9,549 picture images totally through 138 swimwear product catalogues in 1970s to 2014, and 8 web sites. We analyzed formative characteristics such as silhouettes, materials, colors, and textile designs. Because of the shorter cycle of social changes, and various trend, design changes of swimwear are getting diverse. Especially, color and textile design are remarkable. Also, new materials and printing technology make the design of swimming wear more comfortable and fashionable. This research would be a basic research for the design development of swimming wear.

This paper investigates both the spatial patterns of aging population and its formal regional structure in 2010. The results are as follows: first, aging index shows high values in remote mountainous and coastal regions while showing relatively low values in Capital Region and large provincial cities. Aging index has low negative correlation with such variables as population increasing rate, ratio of youth population, ratio of apartments, and ratio of newly built housing. However, aging index shows high positive correlation with variables including ratio of single unit house, ratio of aged peoples' house ownerships, ratio of welfare recipients, ratio of old housing, and number of public healthcare facilities. Secondly, four factors are identified from factor analysis including aging factor, welfare factor, economic vitality factor, and new town factor. The aging level of a region is negatively related to the strong level of those factors. Thirdly, cluster analysis results in four different types of formal regions including rural mountainous coastal type, rural non-capital region type, large metropolitan type, and provincial industrial city type.

With the coming of the digital era, encryption has become common in everyday life. Almost anyone can easily acquire encryption software and use it to prevent unwanted third parties from accessing one's private information. However, the spread of encryption has also seriously hindered law enforcement during the investigation of cybercrimes, which hides incriminating digital evidence in encrypted hard drives and files. Therefore, many countries have attempted to compel criminals to decrypt encrypted evidence and it has been inevitable to examine privilege against self-incrimination as basic right on the side of constitution. This study analyzed the past court decisions on the issue of compelled decryption in the US and whether the Government can compel a defendant to disclose his password in Korean legal system on the constitutional side. Finally, this study suggests an approach to create a legal procedure to make it a crime for a suspect or defendant to refuse to disclose his password to law enforcement for criminal cases in Korea.
