  • Purpose: The aim of this study was to investigate the statistical properties of four previously developed pediatric coronary artery z score models in healthy Korean children. Methods: The study subjects were 181 healthy Korean children, whose age ranged from 1 month to 15 years. The diameter of each coronary artery was measured using 2-dimensional echocardiography and converted to the z score in the four models (McCrindle, Olivieri, Dallaire, and Japanese model). Descriptive statistical analyses and 1-sample t tests were performed. Results: All calculated z scores had P values of ${\geq}0.050$ using the Kolmogorov-Smirnov test. The one sample t test showed that the mean z scores did not converge to zero except in 1 model, and the mean right coronary artery (RCA) z score was less than zero in all 4 models. The smaller RCA diameter in this study could be associated with the more distal measuring point used to avoid the conal branch. The percentage of subjects with extreme z score values (${\geq}2.0$ and ${\geq}2.5$) for the left main coronary artery (LMCA) seems to be higher in the Dallaire (4.9% and 3.3%) and Japanese models (7.1% and 3.8%). Conclusion: All 4 models showed statistical feasibility of normal distribution. More precise instructions would be needed for the measurement of the RCA. The higher percentage of extreme z scores for the LMCA is compatible with the basic understanding of anatomic variation in the LMCA.

  • The goal of this study was to investigate the chemical and microbiological characteristics of kimchi products distributed in Japan (5 brands, J-products) and Korea (2 brands, K-products). When their average analyses were compared, J-products showed higher values in pH, total sugar and acetic acid contents, while K-products showed higher values in number of lactic acid bacteria, sugar alcohol and lactic acid contents including textural hardness or chewiness. In addition, the analysis showed great variation in composition levels regarding pH, total sugar and acetic acid contents of J-products, and this fact revealed that different manufacturing processes are being attempted in Japan. Interestingly, some J-products had high concentrations of acetic acid with little mannitol, as this result implies that some manufacturers in Japan produce kimchi by adding acetic acid or lactic acid to control the rate of lactic acid fermentation. The result of this study elucidates the Japanese consumer's taste preference as well as the manufacturing processes in Japanese companies.

  • From the late 1920s to the 1930s, Korea's fine art community focused on traditional viewpoints as their main topic. The traditional viewpoints were discussed mainly by Korean students studying in Japan, especially oil painters. Such discussions on tradition can be divided into two separate halves, namely the pre- and post-Sino-Japanese War (1937) periods. Before the war, the modernists among Korea's fine art community tried to gain a fuller understanding of contemporary Western modern art, namely, expressionism, futurism, surrealism, and so forth, on the basis of Orientalism, and borrow from these schools' in order to create their own works. Furthermore, proponents of Joseon's avant-garde fine arts and artists of the pro-fine art school triggered debate on the traditional viewpoints. After the Sino-Japanese War, these artists continued to embrace Western modern art on the basis of Orientalism. However, since Western modern fine art was regressing into Oriental fine art during this period, Korean artists did not need to research Western modern fine art, but sought to study Joseon's classics and create Joseon's own avant- garde fine art in a movement led by the Munjang group. This research reviews the traditional view espoused by the Munjang group, which represented the avant-garde fine art movement of the post-war period. Advocating Joseon's own current of avant-garde fine art through the Munjang literary magazine, Gil Jin - seop, Kim Yong-jun and others accepted the Japanese fine art community's methodology for the restoration of classicism, but refused Orientalism as an ideology, and attempted to renew their perception of Joseon tradition. The advocation of the restoration of classicism by Gil Jin-seop and Kim Yong-jun appears to be similar to that of the Yasuda Yojuro-style restoration of classicism. However, Gil Jin-seop and Kim Yong-jun did not seek their sources of classicism from the Three-Kingdoms and Unified Silla periods, which Japan had promoted as a symbol of unity among the Joseon people; instead they sought classicism from the Joseon fine art which the Japanese had criticized as a hotbed of decadence. It was the Joseon period that the Munjang group chose as classicism when Japan was upholding Fascism as a contemporary extremism, and when Hangeul (Korean writing system) was banned from schools. The group highly evaluated literature written in the style of women, especially women's writings on the royal court, as represented by Hanjungnok (A Story of Sorrowful Days). In the area of fine art, the group renewed the evaluation of not only literary paintings, but also of the authentic landscape paintings refused by, and the values of the Chusa school criticized as decadent by, the colonial bureaucratic artists, there by making great progress in promoting the traditional viewpoint. Kim Yong-jun embraced a painting philosophy based on the painting techniques of Sasaeng (sketching), because he paid keen attention to the tradition of literary paintings, authentic landscape paintings and genre paintings. The literary painting theory of the 20th century, which was highly developed, could naturally shed both the colonial historical viewpoint which regarded Joseon fine art as heteronomical, and the traditional viewpoint which regarded Joseon fine art as decadent. As such, the Munjang group was able to embrace the Joseon period as the source of classicism amid the prevalent colonial historical viewpoint, presumably as it had accumulated first-hand experience in appreciating curios of paintings and calligraphic works, instead of taking a logical approach. Kim Yong-jun, in his fine art theory, defined artistic forms as the expression of mind, and noted that such an artistic mind could be attained by the appreciation of nature and life. This is because, for the Munjang group, the experience of appreciating nature and life begins with the appreciation of curios of paintings and calligraphic works. Furthermore, for the members of the Munjang group, who were purists who valued artistic style, the concept of individuality presumably was an engine that protected them from falling into the then totalitarian world view represented by the Nishita philosophy. Such a 20th century literary painting theory espoused by the Munjang group concurred with the contemporary traditional viewpoint spearheaded by Oh Se-chang in the 1910s. This theory had a great influence on South and North Korea's fine art theories and circles through the Fine Art College of Seoul National University and Pyongyang Fine Art School in the wake of Korea's liberation. In this sense, the significance of the theory should be re-evaluated.

  • 탄저병이 발생한 자두에서 분리된 C. acutatum 6개와 C. gloeosporioides 5개 균주에 대한 benoomyl, prochloraz manganese complex, azoxystrobin, pyraclostrobin, tebuconazole 및 dithianon의 균사생장억제효과와 포자발아억제효과를 in vitro에서 검정하였다. 포장 권장사용농도를 기준으로 비교하면, prochloraz manganese가 탄저병 균주의 균사생장을 가장 효과적으로 억제하였다. 포자발아억제에서는 dithianon과 pyraclostrobin의 효과가 가장 높았다. Benomyl, prochloraz manganese complex, azoxystrobin 및 tebuconazole은 포자의 발아를 억제하지는 않았으나, 발아 후 비정상적인 발아관의 신장을 유기하여 균사생장 억제하였다. 본 연구의 결과를 통해 자두 탄저병에 대하여 dithianon은 예방효과, prochloraz manganese, azoxystrobin, tebuconazole 등은 치료효과, pyraclostrobin은 예방 및 치료효과가 높은 약제로 판단되며, 포장 적용시험을 통해 자두의 탄저병을 효과적으로 방제할 수 있는 약제를 선발해야 할 것이다.

  • 본고는 최근 74년만의 개방으로 수많은 관람객이 방문하고 있는 청와대 경복궁 후원 공간의 변화과정을 통하여 후원 경관의 역사적 가치를 규명하고자 조선일기와 조선왕조실록, 도성대지도, 북궐도형, 경복궁 복원기본계획 등의 사료와 도면 등을 근거로 경복궁 후원의 시원과 발달과정을 고찰하였고 이를 통하여 다음의 결과를 도출하였다. 첫째, 조선시대 경복궁 후원은 고려시대부터 명당으로 이름난 지역이었고 당시 남경으로 명명되며 신궁이 조성된 지역이었고 고려시대 이미 풍수도참사상과 주국의 고공기의 영향을 받아 궁성과 궁궐이 조영되었음을 확인하였다. 조선시대 전기 경복궁 후원은 궁궐의 후원으로 각광받지 못하였으나 고종 시기부터 현재까지 국가 통치권자의 생활공간으로서의 장소적 가치를 지니고 있다. 둘째, 후원의 경계는 도성지도, La Coree, 경무대일원, 일본지리풍속대계, 한국사진첩, 조선건축도집, 경성부 도시계획 조사서 등의 문헌을 통해 신무문 밖 현재의 청와대 권역이 경복궁의 경외에 조성된 후원임을 규명하였다. 임진왜란을 겪으면서 황폐화된 지역을 고종시기 중건과정을 거쳐 공사(公私)가 결합된 공간으로 사용되기도 하였다. 일제강점기에는 후원의 전각들이 이건되거나 훼철되며 법궁의 후원으로서의 장소성이 훼손되었으나 광복 후 대통령 관저로 사용되며 다시금 통치자의 장소라는 가치를 회복하게 되었다. 셋째, 경복궁 후원은 왜란과 일제강점기를 통해 공간의 변화가 크게 일어났다. 지형적 변화가 가장 큰 곳은 조선총독부관저가 건립되었던 경농재 일원으로 토지의 용도변화가 빈번하였다. 반면 현 경무대지역과 소정원 옆 수림과 백악의 수림은 전통적 수림의 형태를 계승하며 보존되었다. 이를 명확하게 규명하기 위하여 1:1200의 경무대관저경내부지배치도와 위성사진을 신무문 기준으로 중첩하였고 그 결과 백악에서 발원한 물길이 현재에도 여전히 유존하고 있음을 확인하였고 물길을 따라 오늘날까지도 수림지역이 변화하지 않고 존재하였음을 확인할 수 있었다. 넷째, 전통적 수림경관이 계승된 지역들은 지형의 기능적 변화가 미비하였고 더불어 주요 노거수군이 존치되고 있다. 이 지역에서 확인되는 노거수는 역사적 가치를 가지는 지표수종들이었다. 대표적으로 녹지원에 자리한 반송은 융문당 옆 식재된 반송 중 일부가 보존되어 온 것으로 추정되며 국가원수와 중요 귀빈들의 만찬 시 포토존으로 활용되어온 역사성을 지니고 있다. 마지막으로 청와대 내 경복궁 후원의 가치를 지속적으로 보존관리하기 위해서는 일제강점기 사료들에 대한 발굴을 통해 공간의 가치를 명확히 규명하고 시대별 정원고고학적 층위의 위계를 설정하는 것이 급선무이다. 또한 경복궁으로부터 청와대로 이어지는 조선시대부터 근현대에 이르는 역사경관을 보존하기 위한 근거는 과거부터 영속되어온 청와대 경복군 후원 노거수군의 영역대를 훼손하지 않아야하며 청와대 내 수림을 전수 조사하는 후속연구가 필요하다.

  • This study investigated mechanical properties, drape coefficients and node indices of stretch fabrics. We applied mechanical properties to exhibited tailorability control in HESC and evaluated making-up. The mechanical properties such as tensile, bending, shearing, compression, surface characteristic values, thickness and weight were measured by the KES-F system and drape coefficient by drape tester. The summarized results of this study were as follows; First, stretch fabrics, almost, shown high stretch in weft inserted polyurethane yarn fabric and had a ${\pm}2{\sigma}$(sigma) range of shearing, compression, surface and thickness, except bending and weight, as compared with Japanese women's thin dress fabrics. Second, bending had a positive correlation in stiffness, anti-drape and flexibility & softness. Shearing had a negative correlation in crispness and scroop. Surface properties had a high contribution in fullness & softness. Third, The drape coefficient was found by measuring the mechanical properties according to the obtained regression equation. Forth, many problems are expected in overfeed and cutting operations in sewing process. In the decision of the good external appearance using TVA, only 26 of 55 samples are included in the range of the good external appearance. Fifth, in the regard of the result for sewing control, warp values are not necessary to control in the all kind of items. But weft value in the RT and EM are out of non-control zone. So we need a special management during sewing process.

  • Bojungikgi-tang has been widely used for enhancement of physical fitness in Korea. The convenient, simple, and accurate high-performance liquid chromatography (HPLC) method was established for simultaneous determination of four marker compounds, liquiritin, nodakenin, hesperidin, and glycyrrhizin in Bojungikgi-tang (Buzhongyiqi-tang in Chinese, Hochuekkito in Japanese), a traditional Korean herbal prescription. The column for optimizing HPLC separation was used a Gemini $C_{18}$ column at column oven temperature of $40^{\circ}C$ with 1.0% (v/v) aqueous acetic acid (A) and 1.0% (v/v) acetic acid in acetonitirle (B) by gradient flow. The flow rate was 1.0 ml/min and the detector was a photodiode array (PDA) set at 254 nm, 280 nm, and 335 nm. Calibration curves of four components were acquired with $r^2$ values ${\geq}0.9999$. The recoveries were found to range 92.11~105.68% with relative standard deviations (RSDs, %) value less than 2.50%. The RSD values of intraand inter-day precision were 0.07~2.50% and 0.16~1.99%, respectively. The contents of liquiritin, nodakenin, hesperidin and glycyrrhizin in Bojungikgi-tang were 3.85~3.92 mg/g, 2.27~2.32 mg/g, 4.14~4.19 mg/g, and 3.39~3.45 mg/g, respectively. The established simultaneous analysis method will be effective for quality control of Bojungikgi-tang.

  • The selected physical and mechanical properties of non-certificated LVL circulated in domestic lumber market were investigated and compared to relevant standards. The tested LVL passed the moisture content and the soaking delamination rate limit as per domestic (KS) and Japanese standard (JAS). The evaluated mechanical properties were flatwise/edgewise bending strength, modulus of elasticity (MOE), horizontal shear and compressive strength. The 30 mm-thick LVL showed significantly higher bending strength than that of the 25 mm-thick LVL. The modulus of elasticity (MOE) showed same tendency in the results of bending strength. The edgewise bending strength and MOE were higher than that of flatwise bending strength and MOE. The horizontal shear strength values were also showed similar results to bending strength values. The tested results were compared each other and each products were graded according to JAS 701 grade specification. The failure mode of LVL in bending test showed the similar failure mode of solidwood that failed in a simple tension manner (splintery tension). The glue line failure was severe in 25 mm-thick specimens due to concentration of shear stress in layer discontinuity containing small voids and starved glue lines. In horizontal shear strength test, failure mode of LVL showed the typical horizontal shear failure. Compressive specimens failed with fiber crushing in company with apparent delamination that splitted along the length of the specimens. From the results, the complete bonding between lamination and consistency in thin veneer layer were considered as a critical factor in the mechanical properties of LVL. Moreover, the standard test procedure and specification for non-certificated LVL should be required to check the performance of uncertificated materials.

  • We analyze the time data recorded in Korean astronomical almanacs for the years from 1913 to 1945, which belong to the period in which Japan occupied Korea (1910-1945). These almanacs, published by Japanese scholars, differ from previous almanacs in terms of organization, content, and calendrical methods. In this study, we first extract twelve kinds of time data from the almanacs at the following times: solar terms, rising and setting of the Sun and Moon, transit of the Sun, phases of the Moon (i.e., new Moon, first quarter Moon, full Moon, and last quarter Moon), and eclipses of the Sun and Moon. Then, we compare the time data with that obtained from modern calculations. Even though all time data in the almanacs are tabulated in units of minutes, we calculate the data in units of seconds and determine the root mean square (RMS) deviation values for each kind of time data to estimate the accuracy of the data. Our findings are as follows: First, the kind and tabulation method of time data changes several times. For instance, solar transit time is listed only for six years from 1937 to 1942. Second, the times of two equinoxes and those of a new Moon are considerably close to midnight. Third, there are some typographical errors in the almanacs, particularly in the times of moonrise and moonset. Fourth, the contact times for lunar eclipses represent the times of the umbra and not of the penumbra, which is different from the times for solar eclipses. Finally, the RMS deviation values are approximately 0.5 min on average in all kinds of time data, even though they show slightly large differences in the times related to the Moon. In conclusion, we believe that this study is useful for investigating the time data in the almanacs of other East Asian countries that were published during the same period, such as China, Japan, and Manchuria.
