In 2018, as a subset study to discover indigenous prokaryotic species in Korea, a total of 18 unreported bacterial strains were discovered. From the high 16S rRNA gene sequence similarity (>98.8%) and formation of a robust phylogenetic clade, it was determined that each strain belonged an independent and predefined bacterial species. There were no official report that these 18 species were previously described in Korea; therefore, one strain of Williamsia, one strain of Rhodococcus, three strains of Microbacterium, three strains of Agromyces, one strain of Arthrobacter, one strain of Paeniglutamicibacter, one strain of Pseudarthrobacter, one strain of Nocardioides, one strain of Fibrella, one strain of Hymenobacter, one strain of Deinococcus, two strains of Fictibacillus, and one strain of Paenibacillus are described as unreported bacterial species in Korea. Gram reaction, basic biochemical characteristics, and colony and cell morphologies are described in the species description section.

Six bacterial strains 18JY42-3, 18SH, 18JY76-11, 17J11-11, 18JY14-14, and 18JY15-11 assigned to the phylum Proteobacteria, Firmicutes, and Actinobacteria were isolated from soil samples in Korea. The Cohnella species, strain 18JY42-3 was Gram-stain-positive, short rod-shaped and beige-colored. The Methylobacterium species, strains 18SH and 18JY76-11 were Gram-stain-negative, short rod-shaped and pinkcolored. The Microterricola species, strain 17J11-11 was Gram-stain-positive, short rod-shaped and yellowcolored. The Paenarthrobacter species, strains 18JY14-14 and 18JY15-11 were Gram-stain-positive, short rod-shaped and white-colored. Phylogenetic analysis based on 16S rRNA gene sequence showed that strains 18JY42-3, 18SH, 18JY76-11, 17J11-11, 18JY14-14, and 18JY15-11 were most closely related Cohnella rhizosphaerae (MH497628; 98.8%), Methylobacterium goesingense (MH497632; 99.1%), Methylobacterium populi (MH497635; 99.9%), Microterricolagilva (MH504108; 98.4%), Paenarthrobacter nicotinovorans (MH497641; 100%), and Paenarthrobacter nitroguajacolicus (MH497646; 99.2%), respectively. All the six unrecorded strains showed resistance to UV radiation. This is the first report of these six species in Korea.

맹수현,박유나,Sathiyaraj Srinivasan 국립생물자원관 2020 Journal of species research Vol.9 No.3

In 2019, as a subset study to discover indigenous yeast species in Korea, a total of 20 yeast species were isolated from soil samples collected in Pochoen-si. Among them, eight strains were unreported species. From the high 26S rRNA gene sequence similarity and formation of a robust phylogenetic clade with the closest species, it was determined that each strain belonged to independent and predefined yeast species. The 20 strains were assigned to the genera Aureobasidium (1 strain) and Meyerozyma (1 strain) of the phylum Ascomycota and Cystofilobasidium (2 strains), Filobasidium (1 strain), Naganishia (2 strains), Bullera (3 strains), Leucosporidium (9 strains) and Sampaiozyma (1 strain) of the phylum Basidiomycota. There is no official report of the following species in Korea: Leucosporidium creatinivorum (4 strains), Leucosporidium escuderoi (2 strains), Leucosporidium golubevii (1 strain) and Leucosporidium intermedium (2 strains). Basic biochemical characteristics, colony and cell morphology are also described in the species description section.

In order to investigate indigenous prokaryotic species diversity in Korea, various environmental samples from diverse ecosystems were examined. Isolated bacterial strains were identified based on 16S rRNA gene sequences, and those exhibiting at least 98.7% sequence similarity with known bacterial species, but not reported in Korea, were selected as unrecorded species. 28 unrecorded bacterial species belonging to the phylum Bacteroidetes were discovered from various habitats including wastewater, freshwater, freshwater sediment, wet land, reclaimed land, plant root, bird feces, seawater, sea sand, tidal flat sediment, a scallop, marine algae, and seaweed. The unrecorded species were assigned to 18 different genera in five families: Flavobacterium, Epilithonimonas, Dokdonia, Gillisia, Flavicella, Chryseobacterium, Algibacter, Aquimarina, Lacinutrix, Gaetbulibacter, Cellulophaga, Tenacibaculum, and Maribacter of Flavobacteriaceae, Dyadobacter of Cytophagaceae, Draconibacterium of Draconibacterium_f, Sunxiuqinia of Prolixibacteraceae, and Fulvivirga of Fulvivirga_f. The selected isolates were subjected to further taxonomic characterization including analysis of Gram reaction, cellular and colonial morphology, biochemical activities, and phylogenetic trees. Descriptive information of the 28 unrecorded species is provided.

Isolation and characterization of four unrecorded wild yeasts from the soils of Republic of Korea in winter

박윤아,맹수현,스리니바산 사티야라지 국립생물자원관 2023 Journal of species research Vol.12 No.3

The purpose of this study was to isolate and identify wild yeasts from the soil collected in Gwangju and Pocheon City, Gyeonggi Province, Republic of Korea. Among 10 strains, six strains were already reported, but four strains were unrecorded in Republic of Korea. To identify wild yeast strains, pairwise sequence comparisons of the D1/D2 region of the 26S rRNA gene sequence were performed using Basic Local Alignment Search Tool (BLAST). The cell morphologies were observed by phase contrast microscope and assimilation tests were carried out using API 20C AUX kit. The 10 strains were assigned to the phyla Basidiomycota (8 strains) and Ascomycota (2strains). The unrecorded four yeast strains, NH33, NH19, NH20, and YP416, belong to the phylum Basidiomycota and the genera Buckleyzyma, Leucosporidium, Holtermanniales, and Mrakia, respectively. All strains had oval-shaped and polar budding cells. In this research, the morphological and biochemical properties of four unreported yeast species were characterized intensively, which were not officially reported in Korea

극장 관람료의 합리적 분배에 관한 연구

이현승,맹수현 영상예술학회 2009 영상예술연구 Vol.15 No.-

부율이란 부금비율의 약칭으로 극장에서 거두어들인 입장수입에서 세금을 제한 후, 배급사와 극장 측이 약정에 따라 수입을 분배하는 비율을 의미한다. 국내에서는 통상 서울 지역의 경우 한국영화는 5:5, 외국영화의 경우 6:4(배급사:극장)로 배분하고 있으며, 지방의 경우 한국 영화와 외국영화의 구분없이 5:5의 배분을 하고 있다. 이는 1980년대 후반 할리우드 영화의 직접배급이 시작되면서 할리우드 영화에 비해 한국 영화의 경쟁력이 취약하여 생긴 관행이다. 하지만 한국 영화의 점유율이 15~30%를 유지했던 8·90년대와는 달리, 평균 50~60%의 점유율을 기록하고 있는 2000년대 이후까지 과거의 관행이 유지되고 있다는 것에는 문제가 있다. 또한 2002년부터 한국 영화의 투자 수익률이 하락하고, 투자, 제작, 배급, 홍보 및 마케팅 등 1차 상영관련 시장의 수익률이 적게는 10%에서 많게는 60% 이상의 마이너스 행진을 기록하고 있는 상황 속에서, 극장 상영부분만이 유일하게 이익을 보고 있다는 것은 산업내 왜곡된 수익구조가 존재한다는 의미이기도 하다. 미국이나 일본, 프랑스에서 극장의 관람료 수익 분배 비율은 10~50% 정도이다. 이를 한국 부율 관행과 비교한다면 그리 나쁘지 않은 수익 분배라고 생각할 수 있으나 사실은 그렇지 않다. 세계적으로 윈도우별 영화시장의 규모 중 극장 매출은 31%이다. 즉 극장 이외의 다른 수익 창출 구조가 안정적으로 유지되고 있다는 뜻이다. 하지만 한국의 경우 부가판권 시장의 몰락으로 투자자에게 돌아가는 수익 중 극장 매출이 차지하는 비율은 전체 매출의 약 80%이다. 그렇기 때문에 극장 관람 수입의 합리적인 배분은 그 어느 나라보다 절실한 실정이다. 영화 산업 내 각 분야의 주체들에게 합리적으로 수익이 분배되기 위해서는 다음의 네 가지 사안들이 고려되어야 한다. 첫째, 제작비, 작품의 가치, 흥행 예상 기대치, 마케팅 규모 등을 두로 고려하여 각각의 작품들은 개별적인 부율 책정에 들어가야 한다. 둘째, 미국의 슬라이딩 시스템이나 프랑스의 ‘월요일 협상(au lundi)’, ‘극장의 ‘통로’(Les ‘couloirs’ de salles)’ 방식과 같이 기간에 따라 차별적인 부율을 적용해야 할 것이다. 셋째, 한국 영화산업의 특수성을 고려한 부율 조정이 필요하다. 넷째, 공정한 거래 절차를 유지하여 바람직한 계약 관행을 확립해야 할 것이다. 한국 영화 산업 내에서 부율 책정은 그동안의 오랜 관행으로 각각의 이익집단간의 이해가 상충하여 쉽게 개선이 될 수 있는 문제는 아닐 것이다. 그러나 이는 한국 영화의 투자·제작 기반을 튼튼히 하여 극장에서도 지속적으로 양질의 콘텐츠를 수급할 수 있도록 하기 위함이며, 나아가 각 사업 분야 모두 합리적인 이익 창출을 통한 안정적인 수익 구조를 실현하여 영화 산업 전반의 성장을 구현하기 위함이다. 또한 합리적 부율 책정을 통해 한국 영화계의 과제인 다양성 영화의 안정적 제작·배급의 풍토 역시 마련될 수 있을 것임을 기대해본다. Box-office split stands for the rate of distribution of box-office earnings between a distributor and a movie theater according to an agreement between them after deducing tax from the earnings. In Seoul, box-office split is usually 5:5 (distributor:movie theater) for domestic movies and 6:4 for foreign movies. In domestic local areas, it is 5:5 in general, regardless of the origins of movies. The difference of box-office split between domestic and overseas movies has been derived from the lower competitiveness of domestic movies than Hollywood movies since Hollywood movies were directly distributed in the late days of the 1980s. The market share of domestic movies was only 15~30% in the 1980s and 1990s, but it has changed to 50~60% since the 2000s. In this vein, still maintaining the past practice is problematic. Besides, since 2002, the investment returns of domestic movies have decreased gradually and the earning rates of primary screening-related market activities, such as investment, production, distribution, publicity and marketing, has been reduced in the rate of minimal 10% to maximal 60%. However, there still exist profits in the part of movie theaters. It means that there is a distorted earning structure in the domestic film industry. The rate of distribution of box-office earnings in the United States, Japan and France is 10~50%. Comparing to the domestic rate, it seems to be not bad. However, it is not the case in reality. In the world, the sales amount of movie theaters occupies only 31% of total earnings which come from all the sales windows of movie market. This means that in overseas film industry there are stable earning structures other than movie theaters. However, with the destruction of domestic additional copyright market, the sales amount of movie theaters occupies 80% of investors' total income in the domestic film industry. Therefore, it is urgent to rationally distribute the box-office earnings of domestic movie theaters. In order for the box-office earnings of domestic movie theaters to be rationally distributed among all the parties of film industry, following four alternatives must be taken into account:First, each movie must have its own box-office split considering production cost, the value of movie, expected box-office value, marketing scale and so on;second, like American sliding system or French ‘au lundi’ and ‘Les couloirs de salles’ systems, differentiated distribution rates must be applied on the basis of the period; third, we need an adjustment considering Korean films industry's speciality; and fourth, fair transaction procedures and proper contract practices must be established. Since the existing box-office split is a practice of long standing and the interest of every party is contrary, the establishment and improvement of rational box-office split in domestic film industry seems to be not easy. However, to establish a rational box-office split is necessary for strengthening the investment and production base of domestic movies and supplying quality movies to movie theaters. In addition, it is necessary to establish a rational investment return-based stable earning structure for all the related fields of film industry and thus realize the growth of the film industry in general. The investigator hopes that with the establishment of rational distribution rate, the environment of stable production and distribution of diverse movies, a task of long standing in the domestic film industry, will be created in the future.
