  • Abnormally high waves occurring at the east coast of korea were observed at five field measurement stations and their characteristics were analyzed with the use of wind data provided by the Korean Meteorological Administration. The high waves occurred because strong Donghae twister that was developed by extratropical cyclone blew while high swell arrived at the east coast of Korea. At Sokcho, the most northern site among the five measurement stations, maximum gust speed was 63.7 m/s and significant wave height reached at its maximum of 9.69 m with the corresponding peak wave period of 12.8 s. The reason for appearance of the abnormally high waves is that high swell continued while the twister blew strongly. Moreover, the wind direction was the same as the direction of swell propagation, which maximizes the increase of wave height due to superposition of swell and wind-generated waves. On the east coast of Korea, outbreak of this type of storm waves is very probable in winter season so that it is requested to establish a countermeasure of minimizing possible damage caused by the storm waves.

  • Objectives This study investigated the effects of Cheongyeonsan for allergic rhinitis. Methods First, the GS/MS was used to analyze the effects of Cheongyeonsan by measuring inflammatory markers. Second, 3 groups of 10 6-week-old BALB/c mice were divided into Ctrl (no treatment), ARE (allergic rhinitis-induced without treatment), and CRT (allergic rhinitis-induced after Cheongyeonsan treatment) groups. Ovalbumin (OVA) was used as an antigen to induce allergic rhinitis and sensitization was performed by intraperitoneal injection of 0.1% OVA solution 21, 14, and 7 days before the onset of allergic rhinitis. Allergic rhinitis was induced by dropping OVA solution on the nasal cavity of each mouse for 5 days after the last sensitization. Seven days after the first induction, second induction was introduced by the same method. After making the section, MMP-9, substance P, $TNF-{\alpha}$, $NF-{\kappa}B$ p65, COX-2, iNOS and Nrf, apoptotic cells were observed by Masson trichrome staining, immunohistochemical staining, TUNEL of nasal mucosal tissues of each group. Results GC/MS results showed undecanoic acid. Masson trichrome results showed that the CRT group had less respiratory epithelial damage. Immunohistochemical staining showed CRT group had 58% decrease in MMP-9, 61% decrease in substance P, 55% decrease in $TNF-{\alpha}$, 38% decrease in $NF-{\kappa}B$ p65, 53% decrease in COX-2, 54% decrease in iNOS, 87% increase in Nrf compared to those of the ARE group. TUNEL showed a positive reaction of 84% increase in apoptotic cells greater than that of the ARE group. Conclusions Cheongyeonsan alleviates nasal mucosal damage and reduces inflammatory mediators from allergic rhinitis-induced mice.

  • In this study, characteristics of swell-like high waves in the East Sea were analyzed using observed wave data and predicted meteorological data from the National Oceanic and Atmospheric Administration (NOAA). And, the wave prediction system using the data from the NOAA has been established. Furthermore, the applicability of the system has been verified by comparing the predicted results with the corresponding observed data. For some case, there were two times of wave height increase and the second increase occurred in a calm weather condition on the coast which might cause casualties. The direction of wave energy propagation was estimated from observed wave data in February, 2008. Through comparison between the direction of wave energy propagation and the meteorological data, it turns out that the second increase of waves is originated from the seas between Russia and Japan which is far from the East Sea.

  • 일본 문화청 소속의 정부조직이었던 나라국립문화재연구소가 국가조직의 행정개혁에 따라 현재의 독립행정법인 나라문화재연구소로 변혁하면서 나타나고 있는 여러가지 상황에 대해서 살펴보고자 한다. 나분켄은 동아시아에서도 잘 알려진 국보 호류지금당벽화의 소실이 문화재 분야의 큰 문제로 부각되면서 종합적이고 학술적인 문화재의 연구 보호 종합기관의 설립 필요성에 의해 만들어진 기관이었다. 연구분야에서 보면 초기에는 역사, 건축, 미술공예, 정원, 유적 등 다양한 분야에서 출발했으나 나라지역의 헤이조큐 유적보존 문제가 주요 이슈로 떠오르면서 매장문화재의 발굴 중심으로 그 역할이 강화되는 변화를 겪에 되었다. 그러나 선사고고학이 아닌 역사고고학이 중심이었기 때문에 건축사나 정원사, 보존과학 등 서로 다른 학문이 융합하여 연구할 수 있는 강점이 강화되어 설립목적은 견지하면서 변모하였다. 독립행정법인으로의 변화는 1999년의 제145차 통상국회에서 "독립행정법인통칙법"이 성립되면서 부터였다. 독립행정법인의 취지는 독립 운영하는 쪽이 효율적인 부분을 분리시켜 법인격을 가진 기관으로 바꾸면서 운영교부금을 주무관청으로부터 받아 사용처를 독자적 재량에 맡기면서 이윤을 올릴 수도 있게 한 것이다. 또한 조직과 인사의 자율성을 보장받는 장점도 있으나 평가시스템이 되입되는 정신적 부담도 공존하게 된다. 즉, 민간 방법의 도입에 따라 국가의 부담을 경감하고자하는 의미가 내재되어있다. 나분켄의 독립행정법인화는 동시에 도쿄문화재연구소의 통합을 수반하게 되었다. 도분켄은 원래 미술공예품을 중심으로한 동산문화재 연구와 보존과학부분에 충실한 조직이었으므로 부동산문화재 중심의 나분켄과 통합에 우려의 목소리가 있었다. 그러나 불행중 다행으로 다카마쓰즈카 고분벽화의 열화문제와 키토라 고분 벽화의 보존문제로 인하여 전무후무한 협업연구가 진행되고 양 연구소의 역량을 결집할 수 있는 계기가 되었다. 결론적으로 말하자면, 독립행정법인화는 매년 예산을 중기계획이나 연도계획과 정합성을 유지하면서 독자적인 판단을 통해 편성하는 등 극히 유연한 대응이 가능하다는 장점을 가지고 있는 반면, 문화재 보존을 위한 연구라는 공공적인 목적을 가진 조직이 정부의 의도대로 독자적으로 이윤을 올리는 사업을 확립하여 국가의 부담을 경감하는 방향으로 나아갈 수 있는가라는 부분에서는 의심할 여지가 남아 있다.

  • The Forbidden City in Beijing, China, served as the imperial palace and was a significant political and cultural center during the Ming and Qing dynasties. The complex architectural structure and artistic, symbolic elements of the Forbidden City continue to inspire modern artists and designers. However, there has been relatively little research on developing jewelry designs inspired by the Forbidden City, particularly in terms of color, form, and other elements. This study selected six major buildings from the Forbidden City and analyzed their exteriors and patterns, creating sketches based on this analysis. The colors were analyzed using the HSB color model. The research used the analyzed forms (double-eaved hipped roof, double-eaves gable and hip roof, and single-eaved hipped roof with four ridges), decorations (dragon patterns, three intersecting six-petal lattice), and color differences, the Hall of Supreme Harmony bracelet, Hall of Preserving Harmony earrings, and Hall of Central Harmony ring were completed. The study reinterprets the historical value and artistic beauty of the Forbidden City through contemporary jewelry design, presenting a new design paradigm that harmonizes tradition and modernity.
