유양석 한국차학회 2015 한국차학회지 Vol.21 No.4

With the passage of the Korea Tea Act in 2014, Korea has a new opportunity to reinvigorate the Korean tea industry. Major tea producing countries, such as India, Sri Lanka and Kenya, have established national institutions, tea boards to provide development leadership and oversights for the tea industry. This study examines the concepts and functions of the tea boards in India, Sri Lanka and Kenya. The findings are expected to provide insights and help guide the implementation of the Korean Tea Act. This study found that these countries have a long history of the tea industry starting in the 1830s. Tea boards were established in India in 1954, in Sri Lanka in 1976 replacing the Tea Propaganda Board of 1932 and in Kenya in 1950. The tea board members represent key areas of the tea industry, such as tea plantations, factories, workers, traders, exporters, government officials, and consumers. The tea board contributes to the development of the tea industry using the funds generated from a tax on tea production and exports, and regulates the tea industry through registration and licenses. The board promotes tea through overseas offices and generates tea industry statistics. This study proposes the establishment of a Korean tea board to help implement the Korea Tea Act.

유양석 한국차학회 2015 한국차학회지 Vol.- No.S

Although the Korean tea culture has undergone various phases throughout the periods of the Three kingdoms (57 B.C. - 936 A.D.), Goryeo kingdom (918-1392 A.D.) and Joseon dynasty (1392-1910 A.D.), the ceremonial offerings of tea and ceremonies involving tea were consistently carried out throughout the Korean history. During the last dynasty of Korea, the Joseon dynasty, there were close to 700 documented references of royal court tea ceremonies. Although the procedures of royal court tea ceremonies remained unchanged in the early Joseon dynasty, the royal court tea ceremonies displayed significant changes during the King Jeongjo (正祖) period (r.1776-1800). The royal court tea ceremony began to represent strong national sentiment, popularization of Korean culture and strengthened royal court. These royal court tea ceremony practices established during King Jeongjo continued on until King Gojong, the last king of the Joseon dynasty. This study was conducted to examine the changes in the royal court tea ceremony practices and the influence of King Jeongjo for the development of the changes.

세계 선차(Zen Tea) 제품에 반영된 선차의 개념과 차 종류

유양석,정호철 한국차학회 2019 한국차학회지 Vol.25 No.4

This study examined Zen tea concepts and tea types in the global market. Using the search term of Zen tea on Google, this study identified ten Zen tea websites with the most relevance to this study regarding their tea product offerings. Based on an analysis of these Zen tea websites, this study found that the most representative concepts of Zen teas are harmony, nature, peace, purification of mind, balanced life, healing, and health. The Zen teas are not limited to one particular type of tea but include a variety of teas, such as blended teas, iced teas, herbal teas, powdered teas, and tea bags. Although there are varieties of Zen teas offered in the market, the common emphasis is on improving the quality of life, achieving harmony of community, pursuing a balanced life, taking care of one's body and nature, and pursuing the time of reflection. Zen tea is not just a tea, but it is an embodiment of various cultural elements, such as tea-lifestyle and tea-ware, that promote happiness and better health of tea drinkers. Reflecting these ideals of healing and harmony and natural environment of Zen teas can help Korean teas achieve higher levels of acceptance in the global market. 본 연구는 동양에서 형성된 선차의 개념이 서양 소비자들에게 어떻게 소개되고 있으며 제품에 어떻게 반영되고 있는지를 찾아보고자 하였다. 검색 엔진 Google에 ‘Zen Tea’라는 검색어를 사용하여 선차제품과 연관성이 높은 10개의 사이트를 연구대상으로 선택하여 진행되었다. 조사기간은 2018년 8월 19일부터 2018년 9월 3일 사이에 진행되었다. 소비자들에게 전달되는 선차 제품들의 개념은 공동체의 화목, 천연적 환경, 평화와 화합, 마음의 정화, 균형 잡힌 삶, 힐링, 건강 등으로 나타났다. 선차의 종류는 특별한 종류의 차에 한정된 것이 아니고 블렌드티, 아이스 티, 허브 티, 가루차, 티백 등 여러 종류의 차가 포함되고 있는 것으로 나타났으며 프리미엄 티를 대체적으로 상징하고 있다. 선차를 통하여 삶의 질을 높이고 공동체의 화목을 조성하고 균형적인 삶을 추구하는 생활을 이루며 자신의 몸과 자연을 돌보며, 자연에 가까운 생활을 이루며 정신을 가다듬는 시간을 갖는 것이 소비자들에게 전달되는 선차의 개념이라고 볼 수 있다. 선차는 단순히 차를 뜻하는 것이 아니라 다기 등 여러 문화 요소와 행복과 건강을 상징하고 있었다. 더 좋은 사회를 이루고 삶의 질을 높이려 하는 세계 소비자들의 요망에 부응하고자 하는 것이 선차 제품들의 공통점으로 볼 수 있다. 이런 세계 소비자들의 요망을 우리 차 제품에 반영하면 세계의 소비자들에게 더 호응을 받을 수 있을 것이다. 차와 힐링, 차와 화합의 연관성을 강조하는 선차제품의 개발을 통해 우리 차의 발전과 세계화를 기대해 본다.

유양석,정용훈,최용,임대철,조양자 한양대학교 의과대학 1998 한양의대 학술지 Vol.18 No.2

CTLA-4, which is homologous to CD28, recognizes the same coutner-receptors B7.1 and B7.2. Although initial researches implied that these molecules may act to each other synergistically, recent data suggest that CTLA-4 may acts as a negative regulator of T cell activation. In this study human CD28 and CTLA-4 cDNAs were amplified from PHA-stimulated human peripheral blood lymphocytes mRNAs by using RT-PCR method. IgG1 Fc portion cDNA was amplified from human peripheral blood lymphocytes of patients with febrile illness and fused to C"-terminal parts of CD28 and CTLA-4 extracellular domains. The fusion constructs were subcloned into pCI-neo vector and then transfected into Sp-2/0murine myeloma cell. Stable cell lines were established by geneticin selection and cloning. In the sequence of CTLA-4 cDNA from 3 different healthy persons it was found that 2 sites of bases were different from that published in original paper and submitted to genbank database. The 49th and 331st bases of open reading frame were changed from adenine to guanine and from guanine to adenine respectively. It was confirmed that the 17th and 111th amino acid of human CTLA-4 were alanine and threonine respectively, 5 different human CTLA-4 clones with serial N'-terminal deletion were constructed. CTLA4/L_1 was intact CTLA-4 gene of native form without any form of mutation. CTLA4/L_2 was a mutatn with deletion in gene coding N'-termial 6 amino acids. CTLA4/L_3 was a mutant with deletion in gene coding N'-termial 11 amino acids. CTLA4/L_4 was a mutant with deletion in gene coding N'-termial 16 amino acids. CTLA4/L_5 was a mutant with deletion in gene coding N'-termial 22 amino acids. Level of surface expression of CTLA4Ig on L_1, L_2, L_3, L_4 and L_5 transfectant cell lines were 5%, 3%, -1.5%, 8%, and 6% respectively. These 2 fusion proteins, CD28Ig and CTLA4Ig, would be useful tools for further researches on role of the costimulations in T cell activation.

KEDI 인성검사를 활용한 초등학생 다도⋅예절수업의 효과 검증 연구

유양석 한국차학회 2019 한국차학회지 Vol.25 No.3

This study administered the Korean Educational Development Institute (KEDI) character test to elementary school students to assess the effect of tea ceremony & etiquette class on students’ character virtues in 2018. The study results showed that tea ceremony and etiquette class had a significant and positive effect on students’ character virtues. The levels of student virtues such as honesty⋅courage increased by 8.4%, social responsibility increased by 7.2%, manners by 6.3%, care⋅communication by 4.6%, self-regulation by 3.8%, self-respect by 3.3% and citizenship by 2.2%. There was a significant gender difference in the levels of changes. The boys showed a higher level of increase in social responsibility, self-regulation and honesty⋅courage than the girls. The girls showed a higher level of increase in sincerity, manners, citizenship, care⋅communication, self-regulation and righteousness than the boys. The study found a positive correlation between care⋅communication and social responsibility, honesty⋅courage, righteousness, self-regulation, manners and sincerity. Further research with a greater number of students is needed to re-assess the differences in the level of changes between the gender and school grade. The use of nationally recognized KEDI character test is expected to help to communicate the positive effect of tea ceremony and etiquette education to a larger audience. 본 연구는 다도⋅예절 수업이 학생들에게 미치는 영향을 측정하기 위하여 한국교육개발원에서 개발한 KEDI 인성검사를 초등학교 학생을 대상으로 2018년에 시행하였다. 다도⋅예절 인성검사를 실시한 결과, 다도⋅예절 수업은 학생들의 인성덕목에 유의하고 긍정적 영향을 미치는 것으로 나타났다. 수업 전과 후의 인성덕목별 평균 점수를 비교하면 정직⋅용기의 수치가 8.4% 증가하였으며 사회적 책임은 7.2%, 예의는 6.3%, 배려⋅소통은 4.6%, 자기조절은 3.8%, 자기존중은 3.3%, 시민성은 2.2% 증가하였다. 남학생들과 여학생들의 증가율은 유의한 차이를 보였다. 남학생은 여학생보다 사회적 책임, 자기조절과 정직⋅용기에 더 높은 증가율을 보였으며 여학생은 남학생보다 성실성, 예의, 시민성, 배려⋅소통, 자기조절, 정의에 더 높은 증가율을 보였다. 인성덕목 사이의 상관관계로 배려⋅소통은 사회적 책임, 정직⋅용기, 정의, 자기조절, 예의, 성실과 긍정적 상관관계를 보여주고 있다. 본 연구는 국가적 인성검사를 사용하여 다도⋅예절 수업이 다양한 인성 덕목에 긍정적 영향을 미친다는 점을 객관적으로 재확인하였다는데 의미가 있다. 추후 연구과제로 더 많은 학생들을 대상으로 성별 차이, 학년별 차이를 측정해보는 연구가 필요하다. KEDI 인성검사와 같은 국가적 인성검사를 활용하여 도출된 다도⋅예절 수업의 효과를 더 널리 알리는 것은 다도⋅예절 교육의 확산에 도움이 될 것으로 기대된다.

차(茶) 연관 인문⋅사회과학 연구 동향 분석과 발전 방안

유양석 한국차학회 2023 한국차학회지 Vol.29 No.2

This study examines tea-related humanities and social science research trends through analysis of studies published over the 28-year period from 1995 to 2022 in the Journal of the Korean Tea Society and the Journal of Tea Culture & Industry Studies. The number of tea-related humanities and social science studies published during that 28-year period was 757. This study categorizes them into 22 fields. The most active research fields are tea industry, tea type, and world tea culture, followed by tea spirit, tea ceremony, education, and marketing. Studies with practical impact showed a rapidly increasing trend. Research in the fields of tea living, healing effects, tea space, and tea events showed a rapidly increasing trend over a 10-year period starting in the mid-2000s. Publication of tea-related humanities and social science research showed an annual increase of 20% from 1995 to 2016, and then shifted to a decreasing trend, especially during the years of COVID 19. To expand the influence of tea research, this study proposes ways to strengthen industry-academia collaboration from a selection of tea research topics and the sharing of tea research results.
