  • Geoparks are worth preserving in an environmentally and heritage. Monitoring and public attention are essential for the conservation and protection of geoparks. The use of Unmanned Aerial Vehicles and the Structure from Motion algorithm enables effective monitoring of geoparks that are difficult to manage due to their wide range of manpower, and various spatial data derived from SfM can be utilized to improve awareness of geoparks that have been lacking. In order to prove this, firstly, we created the 3D spatial data by using the UAV and the SfM algorithm, which is one of the National geoparks of the Hantan-Imjin River area. Using this 3D data for Virtual Reality and 3D printing. After that, we verified the possibility of promoting the geopark through a simple online survey. Finally, we propose a method to utilize all the generated data from each step to promote and research for geoparks.

  • This study aims to develop a field trip program for the Hantan River geopark in Pocheon using Orion's field trip model. The selected learning sites were the Hwajeogyeon and Bidulginang Falls, famous geosites of the Hantan River geopark in Pocheon. The field trip program consisted of six preparatory units, two field trip units, and two summary units. The preparatory stage helped reduce the novelty space considering cognitive, psychological, and geographical factors. In the field trip stage, students acquire concepts linked to learning elements in the curriculum scientifically and encourage interest in science. In the summary stage, students organized the geological phenomena observed in the field and inferred the vicinity of the Pocheon Hantan River region. The field trip program was modified to give enough time for observation activities to increase students' interest in science and to connect concepts with learning elements in the curriculum in the outdoor learning phase to allow students' convergent thinking. Implementing the field trip program raises students' interest and attitude in science.

  • This study aims to identify constructs of cultural competency specifically relevant to the Korean society and to test its reliability and validity among human service workers. For the purpose of the study, authors conducted focus group interviews and conferences with human service workers to draw the concept of cultural competency. Further, this study conducted to two separate pilot tests with 20 social workers with practice experiences in order to clarify descriptions and relevance of scale items. Based on the literature review on the concept of cultural competency and analysis of focus group interviews, 40 items were initially constructed and then were reduced to a 32-item scale after two separate pilot studies. Meantime, suggestions made by an advisory group were also reflected in the scale development process. Finally, one hundred ninety four workers in social service agencies were recruited to evaluate the relevance of the scale items in a 5 point Likert scale. Through exploratory and confirmatory factor analysis, 4 main factors were identified: 1) competency to use culturally relevant skills, 2) cultural awareness and sensitivity, 3) cultural knowledge, and 4) efforts to overcome cultural differences. These factors were consistent with sub-concepts of cultural competency in other studies. Confirmatory factor analysis also showed that the model fitness was at the high level and convergent analysis with the similar scale also showed high correlations. Internal consistency also remained at a high level. Based on the results, implication for social work practice and education were discussed.

  • Objective : This study was designed to evaluate the synergistic effect on cytotoxicity of combination with adriamycin and Palginhonhapwhajucwhan, a traditional prescription for cancer treatment in oriental medicine, in Chang, HL-60, Hep-3B and Alexander cells. Methods : We observed cell viability in Chang, HL-60, Hep-3B, and Alexander cells by crystal violet staining. Those cells were treated with various concentrations of adriamycin alone, Palginhonhapwhajucwhan alone and combination of two medications for 10 hr. On condition of $0.5{\mu}l/ml$ adriamycin alone, $15.6{\mu}l/ml$ Paljintanghapwhajucwhan alone and combination of two medications, at first, we observed colony forming of Chang and HL-60 cells. Second, we observed DNA fragmentation by agarose electrophoresis in Chang, HL-60, Hep-38 and Alexander cells. Third, we measured the catalytic activation of caspase-1, 2, 3, 6, 8, and 9 protease in Chang cells and caspase-3 protease in Chang, HL-60, Hep-3B and Alexander cells by using fluorogenic substrate. Finally, we isolated mRNA of Fas in Chang, HL-60, Hep-38 and Alexander cells and observed that Fas gene was amplified by RT-PCR Results : 1. The combination of adriamycin and Palginhonhapwhajucwhan synergistically augmented the cytotoxicity of Chang and HL-60 cells whereas did not in Hep-38 and Alexander cells. 2. Cotreatment of two drugs also markedly inhibited the colony forming ability both in Chang and HL-60 cells. 3. The cytotoxicity of these medicatons was revealed as apoptosis characterized by high molecular wight DNA fragmentaton. 4. The apoptotic cytotoxicity was mediated by activation of caspase-3 protease in Chang cells. 5. Synergistic increase in apoptotic cytotoxicity by combination of two medications was dependent on the expression of Fas in cancer cells. Conclusions : Combination of adriamycin and Palginhonhapwhajucwhan significantly augmented apoptotic cytotoxicity of Fas-positive cells such as Chang and HL-60 cells via acticaton of apoptosis signaling pathway.

  • 최근 국제적으로 생물자원의 중요성이 재인식됨에 따라 이들에 대한 체계적이고 안정적인 정보의 구축 및 활용이 국가경쟁력의 척도로 간주할 정도로 중요성이 커지고 있는 실정이다. 또한, 우리나라는 국토의 64%가 산림으로 되어 있어서 다양한 생물종이 서식하는데 매우 적합한 조건을 갖추고 있다. 이에 따라 산림청과 국립수목원은 국가식물자원정보시스템에 이어 곤충정보에 대한 정보화 사업을 2001년부터 추진해오고 있으며 이 결과로 현재 33만여 점에 곤충표본정보가 구축되기에 이르렀다. 현재까지 국내 유수 곤충표본보유기관 22개 기관이 본 사업에 참여하여 다양하고 내실 있는 정보구축이 이루어져 왔으며 이를 통해 명실 공히 국가적인 곤충자원정보망을 갖추게 되었다. 곤충DB의 국가적인 사업이 추진된 지 6년차에 이르는 2006년도에는 정보통신부의 지원을 받아 14개 표본보유기관이 참여하여 곤충표본DB구축을 중점 추진할 계획이다. 2006년도의 목표량은 곤충표본정보 17,000점으로 기존구축자료 이외에 추가가 필요한 표본정보위주로 구축될 예정이다. 또한, 이미 구축된 곤충표본자원의 활용도와 가치를 높이기 위해서는 더욱 다양하고 많은 자료의 표본을 추가하여 DB화를 추진함은 물론 이들 각각의 정보들을 식물정보와 연계하여 분석 가능토록 하고 GIS시스템을 도입하여 명실공히 국가적인 곤충자원정보의 종합관리가 될 수 있도록 추진하고 있다. 본 사업이 충실히 수행될 경우 국가 주요 생물자원 중 하나인 곤충정보의 DB확대 구축을 통한 전체적인 현황파악 및 체계적인 관리가 가능해 질 것이며, 이와 관련하여 정보화적인 측면, 경제적 측면, 사화 문화적 측면에서 다양한 효과가 기대되며 앞으로도 이에 대한 내실 있는 운영을 위해서는 정부차원의 종합적인 지원 및 관리가 요구되는 시점으로 판단된다.pm3.42$, 저층수 $23.43\pm3.38$이었으며, 전반적으로 해역별 수질기준 I등급 내지는 II등급을 유지하고 있었고, 공간적으로는 외해측으로 갈수록 외해수와 혼합 확산되어 양호한 수질을 나타내었다. 장기적인 변동특성은 세그룹으로 구분되어진다.기 실험결과 용출용매로 증류수와 해수를 이용했을 때, 제강 슬래그에서 용출되는 납, 구리, 카드뮴, 수은의 용출 경향의 차이를 확인할 수 있었고 이에 따라서, 납, 구리, 카드뮴의 용출 유해성은 낮기 때문에 해양구조물로의 제강슬래그 유효이용은 적합할 것으로 판단되었다.im80%$로 계산되었다. 열형광선량계로 측정된 방사선량은 각각 1.8, 1.2, 0.8, 1.2, 0.8 (70 cm 거리) cGy로 측정되었으며, 환자의 복부 표면에서의 서베이메터를 이용한 측정량은 10.9 mR/h였다. 차폐구조물의 사용 시 전체 치료 동안에 태아선량은 약 1 cGy 정도로 평가되었다. 결론 : AAPM Report No.50의 자료에 따르면, 임산부의 방사선 치료 시 태아의 방사선 피폭선량은 5 cGy 이하일 경우에 방사선 피폭에 따른 태아의 위험이 거의 없는 것으로 제시되고 있다. 본원에서 차폐 구조물을 설치하였을 경우에 측정된 태아선량은 약 1 cGy로 측정되었고, 고안된 차폐구조물은 태아에 도달하는 방사선량을 감소시키기에 적합한 설계임이 입증되었다. 아니라 일반종합병원에서도 CTX-M형 ESBL 생성 E. coli와 K. pneumoniae가 존재하며 확산 중임을 시사한다. 앞으로 CTX-M형 ESBL의 만연과 변종 CTX-M형 ESBL의 출연을 감시하기 위한 정기적인 연구와 조사가 필요한 것으로 생각한다., A2-1, B1-1, B2-1의 경우, 강우 일수 감소 이전과 연 유출량 변화는 거의

  • The charnockite of Jirisan area occurs within the Precambrian high grade metamorphic terrane associated with anorthosite body as many foreign examples. Sm-Nd ages were determined from whole rock-garnet pairs, which turned out $1827\pm$32($2\sigma$) Ma for the massive charnockite and $1820\pm$22(2$\sigma$) Ma for the foliated charnockite with $$\varepsilon$_{Nd}(T)$ of $-5.5\pm$0.2 and $-6.0\pm$0.5 respectively. $^{87}Sr/^{86}Sr$ initial ratios calculated with the these ages are 0.71319 and 0.71532 respectively. The fact that massive and foliated charnockites show identical age, identical Nd isotopic initial ratio, and similar Sr isotopic initial ratios suggest that they were generated at the same time from the same material even through their present textures are different. Initial ratios of Nd and Sr of the charnockites are quite distinct from the mantle values indicating the influence of continental crust. Sm-Nd age determined from the titanium bearing anorthositic rocks intruding the anorthosite body, using mineral separates of garnet, plagioclase, and mafic fraction, is $1792\pm$90(2$\sigma$) Ma with $$\varepsilon$_{Nd}(T)=-3.9$\pm$0.2$. The ^${87}Sr/^{86}Sr$ initial ratios calculated with this age are 0.70616~0.70619. The charnockites and the anorthositic rocks occurring in contact each other also reveal the same age within the error, which suggest a genetic relationship between them. However, chemical compositions of the charnockites and Hadong-Sancheong anorthosites cannot be explained by igneous differentiation. Their differences in Nd and Sr initial isotopic ratios indicate different source materials. Therefore, temporal association between them suggests the possibility of the anorthosite acting as a thermal source for the generation of the charnockite as other studies.

A Study on Jeong Su-yeong's Handscroll of a Sightseeing Trip to the Hangang and Imjingang Rivers through the Lens of Boating and Mountain Outings (선유(船遊)와 유산(遊山)으로 본 정수영(鄭遂榮)의 《한임강유람도권》 고찰)

  • In this paper, I argue that the Handscroll of a Sightseeing Trip to the Hangang and Imjingang Rivers by Jeong Su-yeong (1743~1831, pseudonym: Jiwujae) is a record of his private journeys to several places on the outskirts of Hanyang (present-day Seoul) and that it successfully embodies the painter's subjective perspective while boating on these rivers and going on outings to nearby mountains. Around 1796, Jeong Su-yeong traveled to different places and documented his travels in this 16-meter-long handscroll. Several leaves of paper, each of which depicts a separate landscape, are pieced together to create this long handscroll. This indicates that the Handscroll of a Sightseeing Trip to the Hangang and Imjingang Rivers reflected the painter's personal subjective experiences as he went along his journey rather than simply depicts travel destinations. The Handscroll of a Sightseeing Trip to the Hangang and Imjingang Rivers features two types of travel: boating and mountain outings on foot. Traveling by boat takes up a large portion of the handscroll, which illustrates the channels of the Hangang and Imjingang Rivers. Mountain outings correspond to the sections describing the regions around Bukhansan, Gwanaksan, and Dobongsan Mountains. Jeong Su-yeong traveled to this wide span of places not just once, but several times. The fact that the Hangang River system are not presented in accordance with their actual locations shows that they were illustrated at different points. After visiting the riversides of the Hangang and Namhangang Rivers twice, Jeong Su-yeong delineated them in fourteen scenes. Among them, the first eight illustrate Jeong's initial trip by boat, while the other six scenes are vistas from his second trip. These fourteen scenes occupy half of this handscroll, indicating that the regions near the Hangang River are painted most frequently. The scenes of Jeong Su-yeong's first boating trip to the system of the Hangang River portray the landscapes that he personally witnessed rather than famous scenes. Some of the eight scenic views of Yeoju, including Yongmunsan Mountain, Cheongsimru Pavilion, and Silleuksa Temple, are included in this handscroll. However, Jeong noted spots that were not often painted and depicted them using an eye-level perspective uncommon for illustrating famous scenic locations. The scenes of Jeong's second boating trip include his friend's villa and a meeting with companions. Moreover, Cheongsimru Pavilion and Silleuksa Temple, which are depicted in the first boating trip, are illustrated again from different perspectives and in unique compositions. Jeong Su-yeong examined the same locations several times from different angles. A sense of realism is demonstrated in the scenes of Jeong's first and second boating trips to the channels of the Hangang River, which depict actual roads. Furthermore, viewers can easily follow the level gaze of Jeong from the boat. The scenes depicting the Imjingang River begin from spots near the Yeongpyeongcheon and Hantangang Rivers and end with places along the waterways of the Imjingang River. Here, diverse perspectives were applied, which is characteristic of Imjingang River scenes. Jeong Su-yeong employed a bird's-eye perspective to illustrate the flow of a waterway starting from the Yeongpyeongcheon River. He also used an eye-level perspective to highlight the rocks of Baegundam Pool. Thus, depending on what he wished to emphasize, Jeong applied different perspectives. Hwajeogyeon Pond located by the Hantangang River is illustrated from a bird's-eye perspective to present a panoramic view of the surroundings and rocks. Similarly, the scenery around Uhwajeong Pavilion by the Imjingang River are depicted from the same perspective. A worm's-eye view was selected for Samseongdae Cliff in Tosangun in the upper regions of the Imjingang River and for Nakhwaam Rock. The scenes of Jeong Su-yeong's mountain outings include pavilions and small temple mainly. In the case of Jaeganjeong Pavilion on Bukhansan Mountain, its actual location remains unidentified since the pavilion did not lead to the route of the boating trip to the system of the Hangang River and was separately depicted from other trips to the mountains. I speculate that Jaeganjeong Pavilion refers to a pavilion either in one of the nine valleys in Wooyi-dong at the foot of Bukhansan Mountain or in Songajang Villa. Since these two pavilions are situated in the valleys of Bukhansan Mountain, their descriptions in written texts are similar. As for Gwanaksan Mountain, Chwihyangjeong and Ilganjeong Pavilions as well as Geomjisan Mountain in the Bukhansan Mountain range are depicted. Ilganjeong Pavilion was a well-known site on Gwanaksan that belonged to Shin Wi. In this handscroll, however, Jeong Su-yeong recorded objective geographic information on the pavilion rather than relating it to Shin Wi. "Chwihyangjeong Pavilion" is presented within the walls, while "Geomjisan Mountain" is illustrated outside the walls. Handscroll of a Sightseeing Trip to the Hangang and Imjingang Rivers also includes two small temples, Mangwolam and Okcheonam, on Dobongsan Mountain. The actual locations of these are unknown today. Nevertheless, Gungojip (Anthology of Gungo) by Yim Cheonsang relates that they were sited on Dobongsan Mountain. Compared to other painters who stressed Dobong Seowon (a private Confucian academy) and Manjangbong Peak when depicting Dobongsan Mountain, Jeong Su-yeong highlighted these two small temples. Jeong placed Yeongsanjeon Hall and Cheonbong Stele in "Mangwolam small temple" and Daeungjeon Hall in front of "Okcheonam small temple." In addition to the buildings of the small temple, Jeong drew the peaks of Dobongsan Mountain without inscribing their names, which indicates that he intended the Dobongsan peaks as a background for the scenery. The Handscroll of a Sightseeing Trip to the Hangang and Imjingang Rivers is of great significance in that it embodies Jeong Su-yeong's personal perceptions of scenic spots on the outskirts of Hanyang and records his trips to these places.
