Lacquer, in addition to high-end crafts such as lacquerware inlaid with mother-of-pearl, was an important strategic material used in a wide range of fields such as industry, architecture, and munitions during the Japanese colonial era. In particular, as the demand for lacquer used in munitions soared in the 1940s when the war started, a ticket system was introduced to restrict its distribution. Meanwhile, Japan experienced a chronic shortage of lacquer as a result of the rapidly increasing demand for it, and thus went on to import Chinese lacquer after the late 19th century. After the 1910s, the market share of Chinese lacquer reached 90%, and the local situation in China began to affect the supply and demand for lacquer in Japan. To counteract the issue, the Japanese government increased the production of lacquer in Joseon. As for the project to increase lacquer production in Joseon, objective indicators were prepared through a number of tests in the 1910s and 20s, which paved the way for the project to begin in earnest in the 1930s. Lacquer trees were planted and training classes on how to collect lacquer were held throughout the country. The Japanese government promoted the lacquer production industry as a promising side job for Koreans. The project, implemented in various parts of the country, reaped fruitful results, and it provided the basis for lacquer production in Korea that has continued to this day. At that time, the major regions in the southern part of the country where the project was concentrated were Wonju, Okcheon, and Hamyang, regions that are still known today as major production sites. The improved method of collecting lacquer taught to Koreans by the Japanese has now become the main method of collecting lacquer in Korea. This study attempts to identify the current status of the project to increase lacquer production through various records from the Japanese colonial era with a view to contributing to the study of modern lacquer craft history.

Liaison analysis between school grades in genetics contents of biology textbooks under Korean secondary school was performed. Analyzing the liaisons between Inquiry Topics, Inquiry Patterns, Inquiry Process, and Inquiry Situations, we took grades between the 9th and the 12th except 10th: the number of the Inquiry Topics in average were 12, 10, 22 in 9th, 11th, and 12th grades' textbooks each, and their contents for 'repetition', 'variation', 'development', and 'skipping', were 18, 24, 29, and 29% each for between the 9th and 11th grade, and 17, 13, 35, 35% for between 11th to 12th grades, indicating that development and disparities were increased exclusively compared to repeat and variation as grade rises. 'Inquiry process' composed of performances and materials interpretations mainly, but it requires to change improving self-trial learning and extending the balanced inquiry efficiency. Observing the part of Inquiry Situation, there was the most of 'Pure Science', nevertheless 'Social-Technical' Research Situation should take more portion to help STS thinking. 'Readings' was established into 18, 45, 30% of 'repetition', 'change', and 'development' on the transfer of 9th to 11th grade: having the most of 'change' that suggests contents in a different way. However, 'development' and 'skipping' were increased to 48 and 19% with intensified contents in transferring 11th to 12th grade. Contents of advanced biology-related genetics increased on the 11th and 12th grades, significantly intensifying the capacity and level of biology compared to the 9th grades which mainly is composed with classical Mendel's genetics.

In this study, we evaluated the anti-cancer activity and potential molecular mechanism of 70% ethanol extracts of the Berchemia floribunda (BF) which belongs to Rhamnaceae against human colorectal cancer cells. The treatment of BF decreased the cell proliferation in HCT116 cell and suppressed cellular accumulation of Cyclin D1 protein. Inhibition of proteasomal activity by MG132 attenuated BF-mediated Cyclin D1 downregulation and Cyclin D1 was decreased in the cell treated with BF. These findings indicates that BF-mediated Cyclin D1 downregulation may be result from Cyclin D1 proteasomal degradation. Additionally, BF-mediated Cyclin D1 degradation was blocked in the presence of LiCl, a GSK3β inhibitor, but not PD98059, SP600125, SB203580, Bay11-7082, LY294002 an ERK1/2 inhibitor, JNK inhibitor, p38 inhibitor, IκK inhibitor and PI3K inhibitor. Furthermore, BF phosphorylated Cyclin D1 at threonine-286 (Thr286), and LiCl-induced GSK3β inhibition reduced the BF mediated phosphorylation of Cyclin D1 at Thr286. These results suggested that BF may downregulate Cyclin D1 expression as a potential anti-cancer target through GSK3β dependent Cyclin D1 degradation. Therefore, this study provides that the extract of BF has anticancer activity against human colorectal cancer cells. 이상의 연구 결과로 먹넌출 열매 추출물은 GSK3β 의존성Cyclin D1 단백질의 분해를 통해 대장암세포의 생육 억제와 관련이 있는 것으로 확인된다. 본 결과는 대장암의 항암제 개발을위한 소재로 먹넌출 열매의 활용이 가능할 것으로 판단된다.

BACKGROUND: Methane is a major greenhouse gas at-tributed to global warming partly contributed by agricul-tural activities from ruminant fermentation and rice pad-dy fields. Methanotrophs are microorganisms that utilize methane. Their unique metabolic lifestyle is enabled by enzymes known as methane monooxygenases (MMOs) catalyzing the oxidation of methane to methanol. Rice ab-sorbs, transports, and releases methane directly from soil water to its stems and the micropores and stomata of the plant epidermis. Methylobacterium species associated with rice are dependent on their host for metabolic sub-strates including methane. METHODS AND RESULTS: Methylobacterium spp. isolated from rice were evaluated for methane oxidation activities and screened for the presence of sMMO mmoCgenes. Qualitatively, the soluble methane mono-oxygenase (sMMO) activities of the selected strains of Methylobacterium spp. were confirmed by the naphthalene oxidation assay. Quantitatively, the sMMO activity ranged from 41.3 to 159.4 nmol min--1 mg of protein-1. PCR-based amplification and sequencing confirmed the presence and identity of 314 bp size fragment of the mmoC gene showing over 97% similarity to the CBMB27 mmoC gene indicating that Methylobacterium strains be-long to a similar group. CONCLUSION(S): Selected Methylobacterium spp. contained the sMMO mmoC gene and possessed methane oxidation activity. As the putative methane oxidizing strains were isolated from rice and have PGP properties, they could be used to simultaneously reduce paddy field methane emission and promote rice growth.

Mother-of-pearls have received attention as a key craft of Korea. They are being activelyproduced and passed down. Techniques of mother-of-pearls encountered changes in manyways in the modern period. Mother-of-pearls was a luxury item of the upper class in the Koreantraditional society. It turned into just a product by the collapse of the feudal manufacture systemand the change in the production and consumption trends. A conversion to the mass productionsystem was required in this process and the production method of mother-of-pearls was alsochanged. It is confirmed in not only change in introduction of a fret saw and design, but also useof lacquer and making nacre. However, the other changes then that fret saw have not been givenattention until now. Change of technique of mother-of-pearls are related to the industrial policy of the JapaneseGovernment General of Korea. In particular, there were a variety of discussions to improve motherof-pearls as a product consumed in Joseon and Japan, and also as a promising export item in the1930’s. The Central Research Laboratory in Colonial Korea proceeded various tests to increase theproduction of lacquer in Joseon. The improvement test of mother-of-pearls was proceeded as aapplied research. The Product Investigation Research established in the Japanese GovernmentGeneral of Korea attempted improved methods through discussions with Japanese industrialistsrelated to production of mother-of-pearls. The improvement methods were reflected andattempted in a policy. The result of it is recorded in the designation reports of master craftsmen,who worked in Japanese colonial era and were designated as intangible cultural heritageNajeonjang after the independence. These improvement methods suggested by the Japanese Government General of Koreawas limited to improve productivity of mother-of-pearls and developed as an export item. Theimprovement of technique of mother-of-pearls focused on developing production efficiency contributed to the popularization of lacquerware inlaid with mother-of-pearls. However,improvements that were limited to production caused harm to the essence of mother-of-pearls. Now is the time to seek its own way, rather than the way developed by the Japanese GovernmentGeneral of Korea. This study is an attempt to go back to the changes of technique of mother-ofpearlin the Modern period and look at the improvement process through industrial policy of theJapanese Government General of Korea. 나전은 예로부터 한국의 대표적인 공예 중 하나로 주목받아 왔으며, 제작활동과 전승 또한 활발히 이뤄지고 있다. 근대에 나전 기술은 여러 방면에서 변화를 맞게 된다. 전통사회에서 상류층의 사치품이었던 나전은 봉건적 경공장 체제가 붕괴되고 제작과 소비의 경향이 변화하면서 상품으로 변모한다. 이 과정에서 대량생산 체제로의 전환이 요구되었으며, 제작방식에 있어서도 변화를 보인다. 선행 연구에서 파악되고 있는 실톱의 도입과 의장의 변화뿐만 아니라 칠의 사용, 섭패 방식 등 다양하게 확인된다. 그러나 실톱을 제외하고그 외의 변화에 대해서는 지금까지 주목된 바가 없었다. 근대에 나전 기술의 변화는 일제강점기 조선총독부의 공업 정책과 연관을 지닌다. 특히 나전칠기의 생산과 수출이 활발했던 1930년대에 나전칠기를 조선과 일본에서 소비되는 상품에서 나아가 유망한 수출품으로서 개량하기 위한 논의가 다양하게 이루어졌다. 중앙시험소에서는 조선에서의 칠 증산을 위한 채칠시험을 진행했으며, 이의 응용 연구로 나전칠기의 개량시험을 진행하였다. 조선총독부 상공장려관 내에 설치된상품조사연구회에서는 실질적으로 나전 생산과 관련하여 종사하는 일본인 공업가들과의 논의를 통해 개량방안을 꾀하였다. 일제에 의해 논의된 개량 방안은 정책에 반영되어 시도되었으며, 그 흔적은 일제강점기에활동하여 해방 이후 무형문화재 나전장으로 지정된 장인들의 지정보고서에 기록되어 있다. 일제의 이러한 개량은 나전 생산의 효율을 향상시켜 재래공업으로서 수출품으로 발전시키는 데에 한정되어 있었다. 생산 효율의 향상에 초점이 맞춰진 나전 기술의 개량은 해방 이후 이뤄진 나전칠기의 저변화에 기여한 면이 있었다. 그러나 생산에 한정된 개량은 나전 본래의 모습을 해치기도 하는 결과도 발생시켰다. 한국 나전의 정체성을 다시 되찾아 근대의 타율적인 개량이 아닌 우리 스스로의 자율적인 개량 방안의모색이 요구되는 시점에서 본 논문은 근대 나전 기술의 변화를 소급하고 일제의 공업 정책을 통한 나전의개량 과정을 짚어보고자 하는 시도이다.
