이어도 기지에서 관측된 파랑 자료는 주변 수중 암초 또는 지형의 영향을 받으므로 수중 암초의 영향을 받지 않는 지역을 대표하는 주변 대표 파랑 자료로의 환산이 필요할 수 있다. 이를 위하여 본 연구에서는 이론적인 쇄파 모형(Lee, 1993)을 통하여 변환기술상 문제점을 파악하고 원형 천퇴에서의 수치실험을 통하여 천퇴 후면에서 파랑의 변형 정도를 파고비를 통하여 분석하였으며 이를 토대로 이어도 수중 암초에서의 파랑 변형이 관측 지점의 파고에 리치는 영향을 평가하였고 그 결과를 관측 치와 비교${\cdot}$분석하였다.

Accurate prediction of wave-structure interactions is important in the safety and design cost effectiveness of fixed and floating offshore structures exposed to extreme environmental conditions. In this study, regular waves and circular column structure interactions for four circular columns in regular waves are analyzed. To simulate 3D two-phase flow, open source computational fluid dynamics libraries, called OpenFOAM, were used. When the four circular columns are arranged in a square array, the interactions according to the incident slopes of the regular waves are analyzed. The wave run-up in the circular column surface was compared according to the slope of the incident wave. It was confirmed that high amplitude waves are generated between the circular columns due to the interaction between the circular column and the incident wave. It is expected that this analytical result will be used as the basic data of the study on the air gap due to the interaction between the structure and incident wave.

Array observations of the vertical component of microtremors are frequently conducted to estimate a subsurface layered-earth structure on the assumption that microtremors consist predominantly of the fundamental mode Rayleigh waves. As a useful tool in the data collection, processing and analysis, the spatial autocorrelation (SPAC) method is widely used, which in practice requires a circle array consisting of M circumferential stations and one centre station (called "M-station circle array", where M is the number of stations). The present paper considers the minimum number of stations required for a circle array for efficient data collection in terms of analytical efficacy and field effort. This study first rearranges the theoretical background of the SPAC algorithm, in which the SPAC coefficient for a circle array with M infinite is solely expressed as the Bessel function, $J_0(rk)$ (r is the radius and k the wavenumber). Secondly, the SPAC coefficient including error terms independent of the microtremor energy field for an M-station circle array is analytically derived within a constraint for the wave direction across the array, and is numerically evaluated in respect of these error terms. The main results of the evaluation are: 1) that the 3-station circle array when compared with other 4-, 5-, and 9-station arrays is the most efficient and favourable for observation of microtremors if the SPAC coefficients are used up to a frequency at which the coefficient takes the first minimum value, and 2) that the Nyquist wavenumber is the most influential factor that determines the upper limit of the frequency range up to which the valid SPAC coefficient can be estimated.

한국 신화는 우리 민족의 정신적, 역사적 원형이며 상상력의 원천이다. 그럼에도 불구하고 타문화권에 비해 신화의 발굴과 대중적 인식이 현저히 부족하다. 그러므로 한국 신화의 창조적 복원을 통해 게임 컨텐츠를 개발하고, 이를 OMSU 사업으로 확장시키며, 나아가서는 한국 신화를 대중화하고 세계화를 달성할 수 있다. 그 시도로써 콘솔용 액션 RPG 게임의 시나리오 창작과, 게임의 성공 핵심이 되는 그래픽 작업 중 캐릭터 디자인을 전개해 보려고 한다. 단순히 고증을 되살리려는 시도보다는 한국적 요소를 게임 캐릭터에 대입하여 한국적 이미지를 도입하는 데 의의가 있으므로 각 시대만의 독창적 요소를 조합하여 새로운 디자인을 시도하였다. 복식은 사료(史料)와 주변 국가의 회화 및 역사자료를 통합한 고증을 토대로 디자인하고, 이를 판타지풍의 게임에 맞게 새롭게 재조명하였다. 본 연구는 한국의 고대 신화와 설화를 원형으로 시나리오를 창작하고, 한국의 복식 요소를 가미한 판타지 게임 캐릭터 디자인을 포함한 문화 컨텐츠를 개발하는 데 목적이 있다. 시나리오는 주인공이 잠시 머무르는 사후의 세계에서 겪게 되는 여러 가지 여정과 적대역 캐릭터들과의 마찰로 기인되는 에피소드를 중심으로 이루어졌다.

Recently, Japanese cultural contents are being evaluated as a worldwide content. Among them, the animation takes an overwhelming place in the world market as a Japanese representative content. We need to understand that Japanese animation is being recognized world wide, because Japanese culture was grafted in to and it's very important to apply that to our situation. Cultural content to dominate the world has a fundamentally characteristics derived from regional culture. Cultural content includes elements of particular culture prototype. To investigate into cultural content that has globally used and is valuable, in-depth and systematic research for local (country) culture prototype showed be carried out. Our research aim to provide basic data so Korean animation can be developed as axis of Korean Wave. This compares and analyzes the Culture prototype from Korea and Japanese modern civilized media animation. Specifically for the animation shown in the culture prototype, we aim to - Analyze the content of culture prototype shown in Korea's animation: 'Hopi and Chadol Bawi', 'Heung-Bu and Nol-Bu', 'A Admiral's Diary', and 'Oseam'. - Analyze the content of culture prototype shown in Japan's animation: 'Genji', 'The Spiriting away of Sen and Chihiro', 'The Princess Mononoke', and 'Raccoon War Pom Poko'. - Compare and analyze the content of culture prototype depending on classifying criteria shown between Korea and Japan. We finally want to provide the basic data to develop the creation material for the global animation content based on these two countries throughout this research.

Wooden architectural cultural heritages are one of the visible legacies that show the national's identity. Even when the concept of 'the original' of cultural heritages was not accurately understood, the emphasis of preservation and management of cultural heritages was placed on 'preservation of the original form' or 'maintenance of the original form'. Moreover, these days, following the trend of international preservation principles, cultural heritages are considered important as "values as historical objects." This paper is the result of an attempt to determine the scope and content of what parts should be monitored to maintain the original form of wooden architectural cultural heritage. The first thing to be done in monitoring wooden architectural cultural heritage is to check the condition of the ground and foundation. The second is the column. This is because the instability of the column causes damage to the joint with each member and the fitting part, resulting in physical changes leading to damage to the wall. The third is monitor the roof tiles. If the leak continues into the building due to the separation or damage of the roof, the defect should be partially dismantled and repaired, so it should be monitored to maintain its original shape as much as possible. The monitoring range of the base, column, and roof serves as a reference point for identifying what damage is being done to the relevant cultural heritages. In other words, the data at the time when monitoring began becomes the 'original' for the year. Alternatives based on the analysis of monitoring for the preservation of original cultural heritages should be actively introduced. In addition, by sharing the current state and situation of cultural heritages as a result of monitoring with various related organizations, preventive preservation should be established rather than preservation of cultural heritages by "intervention."

The goal of this paper is to analyze the vocabularies and cases related to Kimchi as a cultural history. For this purpose, we extract the vocabularies of Kimchi from the records of Korean Literary Collection in Classical Chinese, Annals of the Choson Dynasty, Records of Daily Reflection, and Diary of the Royal Secretariat. The existing literatures related to Kimchi are confined to some cookbooks, but in this study, we attempt to overcome the existing limitations and adopt a comprehensive and systematic approach. The classic literatures of the Choson Dynasty are mainly recorded in traditional Chinese characters; therefore, the readability is poor, and it is presupposed that a lot of time and effort will be needed for the translation work after securing the data. Therefore, we performed this research with a focus on this part. Next, we tried to reconstruct the archetype of Kimchi culture in the Choson Dynasty by classifying the above materials according to the subject and literature sources.

In order to evaluate the behavior patterns of the ring beam by excavation at the vertical wall with circular section, the measured field datum were analyzed and evaluated in this study. Additionally, stress patterns of the ring beam with the change of excavation depth were estimated by using FE analysis. As the results, it was shown that the tendency of the measured values for the behavior patterns of the ring beam is similar to the analyzed values in FE analysis. From the tendency, it was confirmed that the behaviors of the ring beam due to change of excavation depth can predict by FE analysis using the suggested method in this study.
