The poems in The Rose(1893) represent Yeats’s patriotic attempt to describe the heroic Irish past with “roses” symbolizing ‘eternal beauty’ mixed with pagan wisdom. He concretely suggested “Celtic wisdom” through the epic heroes in Irish myths such as Cuchulain, Fergus, Druid, and Cathleen. They sans, first, wander to get “eternal beauty” as to overcome man’s destiny, living just a day. Second, they don’t pursue impossible knowledge and passionate commitment as shown in Fergus and Cuchulain. Third, they transcend secular passions through the “ancient ways” to go to a Celtic paradise. Fourth, they seek the internal Tree of Life instead of indulging in the external Tree of Knowledge. Fifth, they remember that only such things as the sacrificial behaviors shown by Cathleen will allow us the chances to go to Heaven. So, Yeats wants the Irish and English to seek harmony and reconciliation through the “Celtic wisdom” to get rid of the disharmonious elements in Ireland and English at the end of the 19th century.

자두와 살구의 종간 교잡 과종인 플럼코트 ‘Harmony’ 품종의 생산성 향상을 위해 재식거리 6×3 m 조건에서 덕이 없는 Y자 수형, Y자 팔메트 수형으로 재배하고 수체 생장, 과실 특성, 과실 수확량을 비교하였다. 재식 5년차의 조사 결과에 의하면, 덕이 없는 Y자 수형, Y자 팔메트 수형에서 수체 생장량은 유사하였으나 수관 점유율은 Y자 팔메트 수형에서 높았고, 주당 수확 과실수 및 수확량도 Y자 팔메트 수형에서 높았다. 과실의 과중과 가용성고형물 함량은 수형간에 차이가 미미하였으며 덕이 있는 Y자 수형에서 과실 낙과율이 낮은 경향이었다. 재식 4~5 년차의 결과로 보아 Y자 팔메트 수형은 덕이 없는 Y자 수형에 비해 수관점유율 확대가 빠르며, 과실 착과량이 증가하고, 과실 낙과율을 경감하여 수확량 증대에 기여할 것으로 예상된다.

Based on the findings on similarities and differences in the Korean and Vietnamese cultural features, and the social surveys conducted as part of the project ”Compiling, Publishing and Disseminating the Handbook of Korean-Vietnamese Behavior” by South Korean Studies Center, University of Social Sciences and Humanities, Vietnam National University - Ho Chi Minh City (USSH-VNU-HCM) with the support of the Academy of Korean Studies (AKS) from September to October 2016,the paper covers the three points: First, analyzing similarities that create a special interaction effect between the two cultures. They are ones underlying the spectacular development of the Korea-Vietnam relations during the past time. Among them are similarities in the humanity and tolerance with a distinctive feature of “respect for affection”, playing the most important role;second, analyzing cultural collisions caused by distinctive features in the structures of the two countries’ traditional cultures. They include those of the South Korean culture namely strong hiarachy, high respect of routines, and self-esteem of mono-culture and those of the Vietnamese culture namely strongvillage democracy, low respect of formalities, resistance to imposed culture; and simultaneously analyzing the gaps in the modernity of the Vietnamese workers' culture compared to the requirements of modern production in Korean enterprises so as to point out that they are reasons for the increase of conflicts in Korean enterprises’ operation process in Vietnam; and third, suggesting, based on the analysis, some cultural solutions to increase harmony and reduce conflicts, supporting a sustainable development of the Korea-Vietnam cooperation in Korean enterprises in Vietnam.

For the optimization, we suggest the mathematical modeling of the plane truss which is possible to minimum weight design. In its model, the cost function is minimum weight and constraint function consists of the stress.

무늬 베고니아(Begonia rex) ‘Harmony’s Red Robin’은 독특 한 적색 무늬로 잘 알려지고 인기 있는 실내식물이다. 하지만, 실내 에서는 광환경이 불량하여 무늬의 색상이 퇴색하는 경향이 있어 관 상가치가 감소된다. 본 실험은 무늬 베고니아 ‘Harmony’s Red Robin’ 잎의 적색 무늬 발현에 미치는 광질의 효과를 조사하기 위 해 실시하였다. 실내에서 광원으로 형광등(F)과 LED-백색광(W), 적색광(R), 청색광(B), 녹색광(G), 황색광(Y)과 적·청혼합광(RB, 적색:청색=4:1) 등 7가지로 광 처리하였다. 실내 조건은 기온 25±4℃, 상대습도 60±5%였다. 모든 처리 광원의 광도는 60μ mol·m-2·s-1로 조정하였고 12시간 일장조건으로 8주간 처리하였 다. 그 결과, 생육 특성은 RB, W, B LED에서 양호했다. 전체엽수 는 RB와 B에서 증가했고 총엽면적과 잎의 생체중은 RB, W, B에 서 처리 간에 가장 많이 증가했다. 무늬 발현 특성 중 무늬 비율은 LED RB와 B에서 양호했고 무늬의 적색 발현은 B에서 가장 양호 하였다. 결론적으로, 실내에서 무늬 베고니아 ‘Harmony’s Red Robin’의 적색 발현을 향상시키기 위해 LED 청색광을 적용하는 것이 효과적이나 식물 생장과 인간의 시야 및 미적 환경 등을 고려 할 때 LED 백색광과의 적절한 조합비율의 적용을 위한 추가적인 연구가 필요할 것으로 생각된다.

독특한 잎의 형태, 색상과 질감은 높은 관상가치를 나타내는 특 징들이다. 일반적인 녹색 관엽식물에 비해 잎에 두 가지 이상의 색 이 혼입된 무늬 관엽식물은 원예적으로 관상가치가 높다. 관엽 베 고니아인 B. rex ‘Harmony’s Red Robin’은 긴 엽병과 반짝이는 적색 무늬, 그리고 거친 질감의 잎을 가진 동인도 원산의 근경성 품 종이다. 그러나 자연채광이 불량한 실내에서는 낮은 광도로 인해 무늬 식물 고유의 색상이 퇴색되는 경향이 있어 관상가치가 감소된 다. 식물은 적정 광도에서 가장 잘 자란다. 따라서 관상가치를 유지 하기 위해서는 불충분한 실내 광조건이 개선되어야 한다. 따라서 본 연구는 실내에서 무늬 베고니아 ‘Harmony’s Red Robin’의 생 육 적정 광도를 조사하기 위해 실시되었다. 광원은 보편적 실내 광 원인 형광등(fluorescent lamp)을 이용하였고, 광도에 따른 생육 특성과 무늬발현특성, 색소함량을 처리 전 초기값을 기준으로 분석 하였다. 그 결과, 무늬 베고니아 ‘Harmony’s Red Robin’은 60μ mol·m-2·s-1 광도에서 가장 생육이 양호하였으나 적색발현을 나타 내는 적색도와 안토시아닌 함량은 모든 처리에서 초기값보다 감소 했다. 결론적으로, B. rex ‘Harmony’s Red Robin’의 실내에서 적 정광도는 60μmol·m-2·s-1이었다. 그러나, B. rex ‘Harmony’s Red Robin’의 잎 무늬에 있어서 적색발현을 향상시키기 위한 추가적인 연구가 필요하다.

The probability distribution of wind speeds is a mathematical function describing the range and relative frequency of wind speeds at a particular location . In other word , the behavior of wind velocity at a given site can be specified as a probability distribution function. The accuracy of design wind estimation depends on the choice of an appropriate probability distribution model (PDM) and parameter estimation techniques. Generally, parameters for PDMs are estimated with the method of moments(MOM), probability weighted moments(PWM), and maximum likelihood (ML). In this work , we tried to estimate the parameters of PDMs for wind speed data using a recently developed meta-heuristic approach known as a harmony search (HS) that is a phenomenon-mimicking algorithm. The performance of the HS is compared to the genetic algorithm (GA) and conventional method (i.e.,ML) via simulation and case study.

This paper aimed at modeling a triangular mesh for triangular grid dome by using improved harmony search algorithm. For this purpose, an optimization process to find a regular triangular mesh on the curved surface was proposed and a program for this was developed. The objective function consisted of the standard deviations of the area and the boundary length of each triangle, and the design variables were regulated by the upper and lower boundary conditions which were calculated depending on the nodal connectivity. Triangular grid dome, which initially had consisted of irregular triangular meshes, was selected as target example. In dome model, its result was very approached to the minimum standard deviation of the area and the boundary length of each triangle.

최근 국내 문화수준이 높아짐에 따라 시각적 디자인 요소도 선호하는 바가 달라지고 있다. 식물 또한 선호하는 식물의 종류가 변화고 있다. 이러한 현대인들이 선호하는 식물 중 미적으로 관상가치가 높은 무늬 관엽식물의 색채와 색채조화미를 분석하여 계속적으로 변화하는 무늬 관엽식물의 색채 트랜드를 보여주고자 하였다. 색채측정은 색측기 (X-rite Eye-One Xtreme iO bundle)를 사용하여 색을 측정하였다. 색채조화미 평가는 문&스펜서와 먼셀조화론을 기준으로 분석하였다. 먼셀조화론에서는 Diffenbachia ‘Marianne’가 가장 조화로웠다. 그 외에 Epiprenum aureum ‘Golden Queen’, Caladium ‘Pink Beauty’, Sansevieria trifasciata ‘Laurentii’, Aglaonema ‘Silver King’, Begonia rex, Peperomia sandersii, Calathea macoyana, Alocasia amazonica, Calathea insignis 순으로 색채 조화미가 높게 나타났다. 문&스펜서의 색채조화론에서는 가장 미도가 높은 식물로 Caladium ‘Pink Beauty’, 다음으로는, Diffenbachia ‘Marianne’, Epiprenum aureum ‘Golden Queen’, Peperomia sandersii, Alocasis amazonica, Sansevieria trifasciata ‘Lurentii’, Calathea macoyana, Begonia rex, Calathea insignis, Aglaonema ‘Silver King’등의 순으로 나타났다. 두 조화론에서 조화미가 높았던 무늬 관엽식물의 색채는 yellow green과 green색상으로 좀 더 자연에 가까운 색상 배색이 더 조화롭게 분석되었다. 또한 명확한 색조 차이를 보이는 배색을 보였고 grayish한 색채보다는 채도가 뚜렷한 색채로 배색되었다.

This research was to find out the effectiveness of the horticultural therapy program based on the therapeutic factors and the most meaningful experiences of the clients. For this purpose "Green harmony" program focused on harmony through horticulture was implemented. It is based on the preposition that holistic health is promoted with harmonious relationships with oneself, other people, community and nature. The program has three-fold structure: In innermost it deals with the task of the late adolescent, i.e., self identity, secondly the experience of communication and solidarity in the group, and finally extension of interest to the community. For the therapeutic intervention, questions using the metaphor of the activity were given to the clients for the establishment of self-identity, while group activity and the donation of the works let the second and third purpose accomplished. Outdoor activity, 'Tire garden project', has provided the clients with chances of the contact with nature, cooperation with other group members, and a contest to provoke enthusiasm. Also recycling and greening of the community were possible by utilizing old tires for the containers and by donating the final works to the community. For the evaluation of the result, the effect of the program on the stress of the college students was tested, and the most meaningful experiences during the participation to the program were asked to identify the therapeutic factors acknowledged by clients. "Green harmony" program has brought positive effects on the stress of the clients in spite of relatively short period of five weeks. The clients has acknowledged plant/nature contact and interactions between group members for the most meaningful experiences. This research suggests "Green harmony" horticultural therapy program based on the therapeutic factors is highly applicable for the general populations.

“Harmony”, a new Saxifraga cultivar was released by the National Institute of Highland Agriculture (NIHA), in 2006. A crossing was made between “Hongsaja” with red purple (RPN66A) petals and “Yangwoo” with red-purple (RP61C) petals in 2004. The selection and flower characteristics were investigated from 2004 to 2006 in greenhouse. The first flowering time of “Harmony” is 28th of September, period of flowering is 29 days and number of flowers per plant was 224.1. The flower color shows a red purple (RPN66A) and number of petals was 11.0. Flower width is 1.8 cm and flower length is 1.4 cm. It can be used for pot flower. 50% shading treatment is a good cultural practice against direct sunlight and soft rot disease occurs usually by over-irrigation.

This paper was written in search for the true classical scholar whom Nammyong think is preferable. In accordance with the method of the Text-linguistics, described cohesion, the author analyzed the situationality, intertextuality, and informativity which were shown in Nammyong's poems, and the results were classified into ① situation analysis, ② coherence, ③ the diagram of the synthetical structure, and ④ translation of the poems. The contents were arranged into two parts : ① the desertion of human desires and ② the harmony with the nature and the pleasure of hermit life. The poems and the analysed contents were like these: The themes of 'the desertion of human desires' and 'the harmony with the nature and the pleasure of hermit life' are different, but they are of the same category. This is because the heavenly morals is conserved when the human desires are abandoned, and the harmony with the nature and the pleasure of human morality can be obtained when the heavenly morals are conserved. Nammyong worried for the classical scholars not to cut off the human desires and to flatter themselves in search for the bureaucratic office. He said, if he became dirty because of the human desires, "He would instantly cut open the stomach, take out the dirty things, and flow down them into the river." And also he tried to put these beliefs into practice. He always carried with himself the letters of ‘Piety(敬) and Righteousness(義)', and tried to be pious internally and to be righteous externally. And so Nammyong could succeed in obtaining the harmony with the nature, and could enjoy the pleasure of hermit life.
