The coastal plains of the Puna and Ka' u Districts of the island of Hawaii are a contradiction to the popular view that the island of Hawaii is a tropical rain forest or a vegetated landscape with abundant water sour This section of the island lies in the rain shadow of Mauna Loa a Kilauea Volcanoes and receives less than 30 inches of annual precipita When rain does come. it is in the form of sudden down pours. givi residents of the area little time to collect and conserve water. Due to porous nature of the rock. there is no standing surface water. In spite of these harsh climatic conditions. archeological evidence indic that an extensive agriculture complex existed not only along the coast. into the most remote parts of what is called the Ka'u Desert. Pass through these agricultural areas are historic and pre - historic t systems. These trail systems apparently played a significant suppor role for exchange between the ahupua's (classic land divisions of Haw and the geopolitical districts. The question arises as to how could vast agricultural complexes a heavy foot travel over miles of arid land exist without dependable wa sources\ulcorner While planting - pits and mounds were designed to make most efficient use of available water and conserve moisture(Carter 19 9). people involved in planting also needed potable water for surv Most publications and research papers dealing with the early population this area make only oblique reference to springs and wells which t populations depended upon. The Federal Cave Resource Protection Act(1988) has served as imprtus for the National Park Service to look closer at the lava tu caves and fault cracks within Hawaii Volcanoes National Park. P visitors to these underground areas found large volumes of standing wa in fault cracks. and abundant drip areas with the lava tubes. Re observes noted that in most cases. where the cracks and caves we located in the arid sections of the park. there has been extens modifiacation or utilization of these water sources by the early Hawaii and others. The variety of western containers used for collection indica that these water sources were used during historic times. William E described similar water sources in his narrative of his trip around island in 1823(Eills 1979), This report is directed at documenting recent observations and a stimulating further research into early Hawaiian water collection syst It also explores the implications that power and political influence of e chiefs in the arid portions of Hawaii could have been linked to the con of the water resources.

This study was initiated by the fact that Kangwon Land and large sized resorts was failed the financial benefit to the local residents. This research analyzed the best important tourist resource among the main tourist resource by perception interviewing local residents and related professionals. This study shows that the leisure resource was most important resource field in Jeong-Seon. So more attention to the leisure resources and investment them. Among natural attraction resources 'Hwa-Ahm cave and Hwa-Ahm mineral water' is estimated to have most potential for the strategic financial support. In leisure sector 'High One resort' is judged to be more important attraction resource by professionals but a case of local residents 'Dong-gang Rafting' and 'Rail Bike' were estimated more important resources rather than 'High One resort;. Lastly, in cultural resources, although the importance is a bit behind natural attraction and leisure resources, 'Jeong-Seon 5th day market' and 'Araree village' should be the core linking other related cultural resources. In order to activate tour industry and development of Jeong-Seon area, it is necessary to find identify of regional owned attraction resources and to build tourist attraction infra structure by selecting core bases of existing major attraction points and linking other various resources to those core bases.

Scales generated inside pipes cause negative effects on heat transfer performance, pressure loss and flow rate due to increased thermal resistance and reduced flow cross-sectional area. If these scales are not prevented or eliminated, thermal-fluid performance of the facilities can be deteriorated, or in extreme cases, accidents such as explosion due to overheating can occur. There are two ways to remove the scales, physically and chemically. Removing the scales physically needs specific machines which are expensive, and removing them chemically may provoke corrosion or shorten the age of the facilities. In this study, an eco-friendly pipe scale cleaner using natural organic acid is developed by applying the concept of a limestone cave generation. The manufactured scale cleaner is applied to remove the scales in industrial, water heating and urinal pipes. The results show that this cleaner removes scales more effectively and safely compared to existing scale treatments. Scale removal efficiencies of this work is 1.2~10.7 times for industrial pipes and 1.8~15.5 times for boiler water heating pipes higher than those of conventional cleaners.

John William Waterhouse (1849-1917) is a painter renown for his romantic beautiful femme fatale images in the late 19th century in England. The purpose of this study is to examine the fashion in Waterhouse's femme fatale images. Waterhouse displays the devilism of femme fatale by the symbols of a wicked woman. He emphasized how wicked she is by means of water such as lake, river, and sea as well as symbols associated with demons such as forest, cave, naked woman, long hair, a monster-headed woman looking like an animal, water lily, and garden. On the other hand, he illustrates the woman's style as an image of a typical feminine beauty. Expressing naturally a fine-curved, immature girl's body with marvel-like white and clear skin in a kneeling down or crouching passive rose and depicting it as an innocent and fragile feminine image, he created a passive and lovely image of a young girl. With her eminent beauty and sex appeals, she lured men into danger. Words such as evil, women, and death had been used in describing her as femme fatale to emphasize her wickedness as well as to deliver the meaning across from the inside and to the outside. They also described her as a type of woman with body posture and fashion corresponding to the sexual ideology during the Victorian Age. His description of this fashion image was to show that femme fatale's fashion, which represents attraction and fatality, does not necessarily translate to an active fashion style that emphasizes sensuality. It also tends to minimize resistance and feelings of being threatened. Therefore, it allons us to acknowledge that even girlish body with innocent and frail-looking fashion can be a form of femme fatale, and that fashion styles is essential in forming the image of femininity.

This study examines the restoration project of Sokkuram, and introduces its preliminary plans by the architect Pai Ki Hyung. The restoration project started in 1958 with an inquiry committee of the restoration project, and was completed in 1964. Despite having undergone extensive repair work under Japanese supervision from 1913 and 1923, the repair work caused water leakages inside Sokkuram, and regular cleaning work that began in 1933 caused a lot of damage to the sculpture. In result of the surveys, the top priority of this project was to protect the sculptures inside Sokkuram by improving the environment of the cave. At that time, the architect Mr. Pai participated as a head of the fourth field surveyors to plan the restoration project and to design the preliminary plans. He proposed the installation of a double dome structure to prevent further water leakages on the concrete addition that was built up around the grotto by the Japanese. However, in 1961, the Cultural Heritage Committee of Korea examined the plans of Mr. Pai and immediately rejected them. The factors of the rejection were the omitting of entrance design, system of new double dome structure that presses the existing structure, and these changes that had to be made outside of the drainage plans. The repair work of Sokkuram began in 1961, and the main construction was building double dome structure and entrance installation. In this we realize that Mr. Pai's double dome structure plans were very important key concept of this project. This study attempts to demonstrate the double dome installations that Mr. Pai initially proposed, which ultimately remains as emblematic factors of Sokkuram's legacy.

During a study to discover indigenous prokaryotic species in Korea in 2016, a total of 42 actinobacterial isolates were recovered from various environmental samples collected from natural cave, squid, sewage, sea water, trees, droppings of birds, freshwater, eelgrass, mud flat, sediment and soil. On the basis of a tight phylogenetic clade with the closest species and high level of 16S rRNA gene sequence similarity, it was shown that each isolate was assigned to independent and previously described bacterial species which were assigned to the phylum Actinobacteria. The following 42 species have not been reported in Korea: eight species in two genera n the order Corynebacteriales, 26 species of 16 genera in the Micrococcales, one species of one genus in the Micromonosporales, one species of one genus in the Propionibacteriales, four species of two genera in the Streptomycetales and two species of two genera in the Streptosporangiale. Cell morphology, Gram staining reaction, colony colors and features, the media and conditions of incubation, physiological and biochemical characteristics, origins of isolation and strain IDs of 42 unrecorded actinobacterial species are presented in the species description.

Jecheon is a place of Korean Medicine with many historical characters, medical tales and cultures. One of the most renowned characters is Lee Gong Gi(李公沂), a 扈聖功臣 (title given to the 86 people that escorted king Seonjo during the Japanese Invasion of Korea in 1592) at the level of Huh Jun(許浚) and famous royal physician of Joseon who served King Seonjo and reached the highest position of chief physician. He was recognized for his talent as a royal physician and was conferred with the title of 扈聖功臣 Rank 3 after attending on King Seonjo during the Japanese Invasion of Korea in 1592. Despite the fact that he was a renowned man of medicine, he didn't get as much attention as 許浚 or Yang Ye Soo(楊禮壽) because documents on his work had not been studied. In this study, the author was able to study Lee Gong Gi(李公沂) based on documents such as "朝鮮王朝實錄(True Record of the Joseon Dynasty)", "內醫院先生案(Naeeuiwonseonsengan)", "醫科先生案(Euigwaseonsengan)" and on "避難行錄(Pinanhengrok)" by Yakpo Jeongtak (1526~1605) who was a govemmental pharmacist at the time of Japanese Invasion of Korea in 1592. According to "內醫院先生案" and "醫科先生案", Lee Gong Gi's son Lee Young Nam followed his father's footsteps and became the chief royal pharmacist and 崇政大夫(one of the governmental titles of Joseon Dynasty). As for Jecheon's Korean medical traditions, many forms of medical tales and cultures are preserved such as the tales of Neokgogae, Mountain Ami's medical water cave, Otmaru and Seonsimgol. These tales are divided into various types of great doctors, medical herbs and devoted sons and have been passed down With the origin of traditional medicine still intact. Moreover, ancient documents and artifacts on Traditional Korean Medicine that reflect the area's medical culture have been discovered. Not only is Jecheon a place of medical culture but along with Jecheon Drug Market it also carries on the tradition of medical herbs production and possesses the largest new medical herbs market in Korea. In conclusion, Jecheon is a traditional place of Korean Medicine with many medical cultures and characters from a unique history.

본 연구는 충청북도에 위치하는 지하수로 포화된 삼성석회석광산에서 발생한 지반침하에 대한 사례연구로서, 대상 지역의 지반조사 및 지반안정성평가를 바탕으로 침하원인을 규명하고 향후 침하가능성에 관하여 검토하였다. 조사 및 안정성평가 결과에 의하면 채굴구역은 강우 유입으로 인한 전단강도 저하로 전반적으로 불안정하게 평가되었으며, 미채굴 구역의 침하발생 주요 원인은 지하수위 하강에 기인한 것으로 판단된다. 향후 침하 가능성과 관련하여, 채굴공동 천단의 암반층 두께가 얇은 구간이나 인장절리 발달이 활발한 구간이 존재하고 채굴공동 주변의 지반상태가 불량하므로 침하가 발생할 경우 침하의 영향은 주변 지반으로 확산될 가능성이 있다. 또한 연구지역 내 석회암 분포지역에서는 석회암층 내자연 용식공동의 함몰이나 양수 등 인위적 요인의 영향으로 인해 지하수위 저하나 강우침투에 의한 공동에서의 유로변화 및 수위변화가 발생할 경우 추가적인 침하가 발생할 수 있으며, 이에 대한 보강 및 관리 대책이 필요할 것으로 판단된다.
