This study investigates the characteristics(form, material, structure, method of construction, vegetation) and model of lotus pond in Joseon Royal Tombs for conservation and restoration. The objects of study are the lotus pond of Namyangju Gwangreung, Hyoreung, Gimpo Jangreung and Sungreung that are well-preserved and the record is remaining. The form is two plane types, square shaped include an island and square shaped. The pond is 7.5~81m in width and 6.5~45m in length and the island is 8~16m in diameter. The depth of water is 0.5~1.2m and the cross section form is narrow bottom and wide top. The material of shore protection is soil in Hyoreung, Gimpo Jangreung and Sungreung. The bottom is mud in all sites. I think that the main material of the lotus pond in Joseon Royal Tombs is soil. The lotus pond is built by soil bank in the structure and method of construction. The water supply and drainage are worked through the culvert. There are many kinds of plants in the lotus pond today, however I think that the model of vegetation of lotus pond in Joseon Royal Tombs is lotus the inside, pine tree, fir tree and flowers the around and pine tree the inside of island in compared the present and the old literature. In comparison with the lotus pond in Joseon Royal Tombs and the lotus pond in the Joseon palace, the material is the biggest difference. The main material is soil in Royal Tombs but isodomic in Royal Palace. I think that the difference of material in between two causes the difference of structure and method of construction. The Royal Tombs is valuable in architecture, landscape and esthetics, this study investigated the characteristics and model of lotus pond in Joseon Royal Tombs. I think that this study serves as a momentum to find a traditional technique in Royal water space and offer the foundation to plan in the contemporary water space.

This article is to study the ancient Korean make-up based on ancient men's and women's facial decoration. The adornment is mainly about make-up, but I didn't employ make-up in this article on the ground that it isn't an appropriate concept in men's case. The study on the ancient Korean make-up has been conducted on the basis of Goguryeo mural paintings excavated in the tombs. Contrary to the Baekje and the Silla Kingdoms, Goguryeo women's make-up carne to fashion like China. The Goguryeo mural paintings depicted women's make-up which painted their faces white and lined on the eyebrows to make them raise toward their foreheads after removing their own eyebrows. They outlined their mouths smaller than their own and, in some occasions, applied make-up differently on the upper lip and the lower lip. As the time passed by, women applied the blusher, which attests to the fact that make-up of those days was considerably developed. Unlike women, men didn't put on cosmetics but they grew beard as a symbol of adults. The beard had a diversity in shape such as goat-shaped and fan-shaped beards. It can be understood that women's make-up was applied as a manifestation of adults like men's growing beards.

Four children's cosmetic sets were purchased online, labeled for use from 4 years of age, and 81 components of each were analyzed for lead, cadmium, arsenic, antimony, nickel, cobalt, copper, chromium, and mercury by inductive coupled plasma - mass spectrometry (ICP - MS). The average metal concentrations were as follows: 0.82 ㎍/g for lead, 0.03 ㎍/g for cadmium, 0.97 ㎍/g for arsenic, 0.52 ㎍/g for antimony, 2.32 ㎍/g for nickel and 0.01 ㎍/g for mercury which was lower than the acceptable standards for all products. Higher mean values of lead, antimony, cobalt, and copper were detected in imported than domestic products (p < 0.05). There was a statistically significant difference in the average values of heavy metals according to the type of cosmetics (p < 0.05), with eyeshadow showing the highest mean values of arsenic 2.47 ㎍/g, nickel 6.36 ㎍/g, and chromium 11.06 ㎍/g. and the highest mean concentrations were 1.20 ㎍/g for lead, 1.17 ㎍/g for antimony, and 23.60 ㎍/g for copper in blusher. The levels of cobalt in the 81 children's cosmetics were ND ~ 5.23 ㎍/g, copper were ND ~ 379.61 ㎍/g, and chromium were detected ND ~ 36.95 ㎍/g, respectively. Brown colored cosmetics had the highest mean concentrations of nickel and cobalt. Purple-colored cosmetics had the highest mean concentration of lead and chromium.

The purpose of this study is to understand the environmental traits and significance of the pond place that appears in historic maps in 'Dongchon(東村)', which is the eastern section within the fortress wall of Hanyang. We reviewed various documents and maps to identify the name of the pond, and of those materials we followed the name provided by official national records and geographical titles to designate it 'Eouidongji Pond(於義洞池).' The results of the research showed, first, that from the standpoint of location and environmental characteristics, that the area of the Eouidongji Pond was an area that contained a pastoral atmosphere within the city. It was located in an area where the waters flowing from the mountains gathered, and the boundaries of the pond would change based on water levels within a plot of land about 2,000pyeong(app. $6,600m^2$) in size. Second, when seen from the perspective of its creation background, the Eouidongji Pond seems to have been a naturally occurring pond which was modified when the water system was managed in the city at the beginning of the dynasty. In addition to its role as a reservoir, it was operated as a lotus pond(蓮池) to offer lotus(蓮) related by-products. With the nearby detached palace being actively used, it seems the pond was managed at the same time. The pond had already been filled in by the early 20th century, and although there were efforts to reconstruct the pond, it was eventually destroyed as the area was included in the site of a school during the colonial period. Third, the Eouidongji Pond was appreciated in many cases by individuals or admired as part of the natural landscape by viewing it from afar. In addition, it provided entry landscape near the road entering Dongchon, and was a location that was easily visited in connection with other nearby pleasure grounds. Through studying the location and environmental characteristics, the background of its creation and destruction, operation and management by time period, usage at the time, and characteristics of scenery appreciation of Eouidongji Pond, the Eouidongji Pond was a pond of high practical value to the nation, as it supplemented the water system in the city and was able to provide lotus harvests for the nation. In addition, from a urban environment perspective, it was a lateral landmark with a large area, as well as an effective boundary. It was an open area that the people of the Hanseong-bu could freely use, and it had a high public value due to its ease of accessibility.

유역모형을 통해 우심하천을 제시하는 방법은 많은 노력과 시간이 요구되는 경우가 많다. 본 연구에서는 국가배출부하량 자료를 사용하여 간단하게 오염원별/오염물질별 수질 관리가 요구되는 하천을 선정하는 방법을 제시하고, 우심하천을 선정하였다. 적용 유역은 한강 수계에서 가장 복합한 댐 유역인 충주댐 유역으로 결정하였다. 충주댐 유역의 소유역별 배출부하량을 활용해 하천 관점의 배출부하량을 산정하였다. 하천 관점의 배출부하량 (Stream Total Loads, STL로 명명)은 임의의 하천으로 유입되는 모든 소유역의 배출부하량 합계를 면적 합계로 나누어 산정하는 방법이며, 임의의 하천 지점에서 상류의 모든 소유역이 포함된 단위면적당 배출부하를 의미한다. 따라서 댐 유역 말단의 STL은 유역 전체의 단위면적당 배출부하로 표현되며, 유역 전체의 STL보다 높은 소유역이 연결된 하천을 댐 호소 관점에서 볼 때 관리가 필요한 하천이라 할 수 있다. 댐 유역 말단의 STL은 점오염원-BOD 0.617 kg/km²/day, 점오염원-TP 0.038 kg/km²/day, 비점오염원-BOD 2.909 kg/km²/day, 비점오염원-TP 0.237 kg/km²/day로 산정되었다. 점오염원에 대한 BOD 관리하천은 창리천, 장평천, 지장천하류 등 15개 소유역, TP 관리하천은 주천강시점, 창리천, 주천강상류 등 20개 소유역으로 나타났다. 비점오염에 대한 BOD 관리하천은 주천강시점, 장평천, 제천천하류 등 13개 소유역, TP 관리하천은 주천강시점, 장평천, 주천강상류 등 16개 소유역으로 나타났다. 또한 전체 배출부하에 대한 비점오염원의 배출부하비는 BOD 82.5%, TP 86.2%로 점오염원보다 높았다. 따라서 우선 관리 대상 하천은 TP 비점오염원, BOD 비점오염원, TP 점오염원, BOD 점오염원 순으로 계획될 필요가 있다. 향후 유역 모델링을 수행하고, STL 산정 결과와 비교하여 우심 하천 선정에 대한 적합성을 평가할 예정이다.

The archival content listed arbitrarily makes it difficult for users to efficiently access the records of major economic policies, especially given that they use it without understanding the required period and context. Using the text mining techniques in the 30-year economic policy direction from 1991 to 2021, this paper derives economic-related keywords and changes that the government mainly dealt with. It collects and preprocesses major economic policies' background, main content, and body text and conducts text frequency, term frequency-inverse document frequency (TF-IDF), network, and time series analyses. Based on these analyses, the following words are recorded in order of frequency: "job(일자리)," "competitive(경쟁력)," and "restructuring(구조조정)." In addition, the relative ratio of "job (일자리)," "real estate(부동산)," and "corporation(기업)," by year was analyzed in terms of chronological order while presenting major keywords mentioned by each government. Based on the results, this study presents implications for developing and broadening the area of archival information services related to economic policies.

The purpose of this study is to consider practical examples of the method of utilizing plant material 'lotus' used by the ancients, and the value and meaning they wanted to get from it. The method of this study to do this is descriptive study to consider and interpret poem and painting reflecting impression and concept world of lotus. Summary of this study is as follows. First, ornamental value of lotus could be divided in effect of group plant and detail value held by the flower, the leaves and the stem. Especially, group plant lotus in large site provides unique landscape differentiated form other flowering plants. As well, another feature of lotus is its high ornamental value spread in detail elements including the flower, the leaves, the stem and the lotus seed. Second, fragrance expressed 'Hyang-won-ik-cheong(香遠益淸)' is an important charm of lotus. Lotus was utilized as olfactory element providing fragrance. The ancients considered lotus fragrance not only for enjoy but as symbolic object comparing noble man's dignity so that they expressed it in poem and painting. Third, lotus was utilized as acoustical element. That is, the sound of raindrops harmonizing the surface of water and wide lotus leaves was called 'hearing lotus fond and rain', enjoying it as classic grace. Fourth, summer play lotus sightseeing was called mind wash up meaning 'washing the mind polluted by the mundane world'. Such poetic taste was widely enjoyed by various classes from general public to royal family. Besides, poetic taste related with lotus is the method of drinking alcohol using the feature of big lotus leave and vacant stem, called 'Beog-tong-ju(碧筒酒)'. And in the Joseon dynasty period, when the distinction between the man and the woman influenced by Confucian, lotus seed and 'lotus collecting song' was important sign to express romance between man and woman. Lotus has been enamored by wide classes transcending cultural background as thought and religion since ancient times. Due to such reasons, various symbolic meaning of lotus and planting examples related to religious facilities as temples could not be considered in various manner is limitation of this study, and which is research project for the future.

This study is intended to analyze the impact of PMMA on color changes comparatively by making 2 types of cheek color items with red-color pigments: one containing PMMA, which is one of the recently developed circular polymers and used when producing color make-up items that have aero powder as the chief ingredient, and the other without it. To accomplish the purpose, we have reviewed literature on raw materials that have aero powder as the chief ingredient. Also, after making compounds of PMMA and pigments lot aero powder, such as Talc, Mica, OMC Talc As, Mica As, we examined them compared to those without PMMA using spectrophotometer, a questionnaire survey, and Digital camera. Besides, the particles were analyzed using SEM. As a result of the analysis, cosmetics containing PMMA represent more vivid and rich colors, putting on one's face softly. Since the entire specific surface area of PMMA is large enough to absorb oil evenly, it yields vivid and rich colors. But, Mica, one of natural pigments, shows a result as opposed to that of Mica As, one of silicon-compounded pigments, suggesting that pearl effect may possibly causes defused reflection. Based on these findings, it is expected that cosmetics will have more vivid colors, or improved color presentation, as well as the softer sense of touch when a circular polymer of PMMa is added to the manufacturing process of color make-up items.
