  • 'Lucky one' is a new orchardgrass (Dactylis glomerata L.) variety developed by the National Institute of Animal Science (NIAS) in 2014. Four superior clones were selected and polycrossed for seed production to develope this new variety of orchardgrass. The agronomic growth characteristics and forage productivity of 'Lucky one' were examined at Cheonan from 2010 to 2011. Regional adaption trials were conducted in Cheonan, Hoengseong, Jinju, and Jeju from 2012 to 2014. 'Lucky one' showed growth habit of medium type in fall and spring. It has short flag leaf length with long upper internode. Plant height of 'Lucky one' was 3 cm more than that of control variety, 'Amba'. Its heading date was 2 days later than that of control variety 'Amba'. Characteristics such as waterlogging and disease resistance of 'Lucky one' were stronger or better than those of control variety, 'Amba', Especially, dry matter yield of 'Lucky one' (16,191 kg/ha) was increased 38% compared to that of control variety, 'Amba'(11,778 kg/ha). Nutritive feed values of 'Lucky one' appeared to be similar to those of control variety 'Amba' except in Vitro dry matter digestibility (IVDMD) and crude protein content.

  • A survey was conducted to investigate infection of anisakid nematode larvae in 243 wild marine fishes caught from the southern coastal area of Korea between 2010 and 2012. The samples comprised fishes from 9 orders, 30 families and 50 species. Total infection rate of anisakid nematode larvae was 10.7% (26/243 fish), which comprised from Yeosu, 7.4% (7/95) in 2010 and 22.7% (5/22) in 2011; from Jeju, 8.2% (5/61) in 2011; from Wando, 40.9% (9/22) in 2012. Anisakid nematode larvae were not detected in Tongyoung and Wando samples in 2011. Molecular identification of the 89 worms from 26 fish was conducted by PCR-RFLP and/or sequence analysis of internal transcribed spacer (ITS) region of ribosomal DNA. From the results, 6 kinds of anisakis species were identified: Anisakis pegreffii (infection rate: 53.9%, 48/89 worms), Hysterothylacium aduncum (38.2%, 34/89), H. fabri (3.4%, 3/89), hybird (A. simplex X A. pegreffii) (2.4%, 2/89), A. simplex (1.1%, 1/89) and Raphidascaris lophii (1.1%, 1/89). The rate of single infection was 80.8% (21/26 infected fish), while 19.2% (5/26) showed mixed infection with 2 to 3 different anisakis species.

  • Most of the Korean performing arts markets are not only small but also show their limitations in terms of their role as a platform for the promotion of performing arts and future growth prospects. This study started from the perception that the domestic performing arts markets need the cooperation between the markets in order to overcome the current situation and become the representative performing arts markets of Asia. To do this, we conducted surveys and in-depth interviews on market collaborations with domestic performing arts officials such as PAMS, Jeju Haevichi Art Festival and G-FAFE. For successful inter-market collaboration, the first is to change ideas and thinking about collaborations, second, to select programs suitable for direct supervision and collaboration based on evaluation of comparative advantage, and third, to establish and operate the 'Performing Arts Market Collaboration Promotion Committee(tentative name)'. And the fourth, starting from the sharing of the network that is most required at this stage, it is necessary to develop the sharing of manpower and places through mutual financial support or sharing between the central government, the metropolitan municipalities.

  • Two unrecorded naturalized species, Stachys agraria Schltdl. & Cham. and Dracocephalum moldavica L (Lamiaceae), are newly reported in Korea. Stachys agraria and D. moldavica were found at Seogwipo-si on Jeju-do and at ChunChen-si in Gangwondo in Korea, respectively. Stachys agraria is distinguished from other related Korean taxa by corolla of 2.4-5.2 mm long with six to twelve flowers in the node. Its local name is "Ae-gi-seok-jam-pul" based on shorter than longer corollar. Dracocephalum moldavica was distinguishable from other Dracocephalum in Korea by the following combination of characters, oblong to ovate-triangular ($1.7-2.4cm{\times}0.8-1.2cm$) leaves and rough crenate at the margin. This taxon is referred to as 'Hyang-yong-meo-ri' in Korean based on its fragrance. We provide a description, illustrations, photographs, and a key of related taxa in Korea.

  • This study was performed to investigate and measure the antimicrobial activity of evergreen woody species extracts on Trichophyton mentagrophytes. To do this, leaves and stems were collected from Wando and Jeju islands, and were used for the extraction with different solvents (i.e., distilled water, 80% ethanol, and 100% methanol), and at different ultrasonic extracting times (i.e., 15, 30, and 45 minutes). The experiment was conducted by using the agar diffusion method. The clear zone was measured after incubating the paper disc containing the plant extract in a bacterial culture medium. The controls were synthetic antimicrobials, methylparaben and phenoxyethanol, at concentrations of 0.4, 1, 2, and 4 mg/disc. Altogether, extracts of 56 out of 64 species used in this study had inhibitory activity, which confirmed their antimicrobial activity against Athlete's foot. Among them, the crude ethanolic extract of Elaeocarpus sylvestris in 45 min showed a zone of inhibition < 20.2 mm, while the clear zone of Actinodaphne lancifolia ethanolic extraction for 30 min was 23.5 mm. Also, Quercus acuta, Dendropanax morbiferus and Daphne odora showed clear zones of 28.0 mm (45 minutes ethanolic extraction), 20.5 mm (45 minutes crude methanolic extraction) and 19.7 mm (45 minutes methanolic extraction), respectively. Thus, these results confirm that the extracts of evergreen woody species have therapeutic potential against Athlete's foot, and suggest that in order to extract adequate amounts of antimicrobial substance from the plant sources, ideal extraction condition has to be considered.

  • In terms of the fact that Innovation School is the main agent which encourages the innovation of school culture, As it has been ten years since the Innovation School was enforced, we do need a practical, indepth study on the quality of policy management. To make this actualize, this study is for analysis and comparison of basic values and operating evaluation plans which have been managed by Metropolitan City Office of Education(MCOE) & Provincial Office of Education(POE). Each of MCOE & POE have their own vision. Those visions are such things; 'Education for All' for Gangwon, Busan, Chungbuk. 'Future School Orientation' for Gyeonggi, Gyeongnam. 'Educational Community Realization' for Gwangju, Seoul, Ulsan, Jeonbuk, Jeju. 'Normalization of Public Education' for Sejong, Incheon, Chungnam. Like such things, each office possesses different vision by their distinct characteristics and in principle, all emphasis on publicness, democracy, and creativity. Management evaluations of the Innovation School is operated by Self-assessment, Intermediate evaluation, and Extensive assessment. The process and evaluation index of Intermediate evaluation and Extensive assessment are similar. Especially, Those assessment have significance in a role of administrating its management of each school and a role of offering associated documents of educational policy with educational renovations with feedback and some good examples.

  • In this study, the projection of future heating and cooling degree days (HDDs and CDDs) has been conducted over South Korea for the period 1996~2005 with 2046~2055 and 2091~2100, using CCSM3 and MM5 simulations driven by the six IPCC SRES emission scenarios (A2, A1B, A1FI, A1T, B1, and B2). Annual mean surface air temperature increases by $1.2{\sim}3.4^{\circ}C$ at the end of the 21st century comparing to the present-day (1996~2005) in South Korea. HDDs decrease by 8~25% and CDDs increase up to 242~1,448% with corresponding changes in temperature. These increases and decreases also change the duration of HDDs and CDDs. HDDs duration decreases by 1 month, while the expansion of CDDs duration is much longer than 2 months. Thus, projected future HDDs and CDDs changes appear that cooling energy demand in summer season would increase and heating energy demand in winter would decrease in the future. Especially, these remarkable changes would be obvious at high mountain area, Gangwon-do and at south area, Jeju island. In the sense of future energy supply and policy, electrical energy for cooling in summer could be getting much more its importance rather than fossil energy used for heating in winter.

  • Hwangmichal, a yellow waxy corn hybrid, is a single cross hybrid developed in 2014. This hybrid was created by crossing the seed parent KY30 and pollen parent KY9. Hwangmichal has yellow kernels with a conico-cylindrical ear shape. The days to silking of Hwangmichal were similar to that of Ilmichal, a check hybrid. The ear height ratio of Hwangmichal was 50%, which was lower than that of Ilmichal, and its number of tillers was less than that of Ilmichal. The ear size of Hwangmichal was smaller than that of Ilmichal and the kernel set ratio was 89%. Its sensory evaluation was better than that of Ilmichal. The carotenoid content of Hwangmichal was $32.2{\mu}g/g$, which was much higher than that of Ilmichal. Lodging resistance of Hwangmichal was better than that of Ilmichal. Although the number of fresh ears of Hwangmichal was more than that of Ilmichal, the weight of fresh ears was lower than that of Ilmichal. The flowering period of its parent lines was well matched and seed production was 3:1 at a planting density of parent lines of more than 2:1. It is adaptable to the whole country except for Jeju-do. The plant variety protection right of Hwangmichal was registered in June 2017, and its grant number is 6728.

The Poet Kim Shi-Jong living in both Joseon and Japan: the Meaning of 'Zainichi' Expressed in Epic Poem Niigata (조선과 일본에 사는 시인 김시종 - 장편시집 『니이가타』에 표현된 '재일'의 의미)

  • This article considers the meaning of 'Zainichi (在日)' expressed in epic poem Niigata (1970) written by Korean-Japanese poet Kim Shi Jong. Kim sets two points in his creation of poetry. One is summer of liberation released from Japanese colonial domination in 1945. The other is Japan where he lives as a Korean-Japanese. These two points have made him think about the meaning of living in post-colonial era and the national division of Korea, his home country. His thought like this is well expressed in his epic Niigata. Niigata was written in 1959 when the ship returning to North Korea departed from Niigata of Japan. However, Kim couldn't return to his home country at that time. He stowed away from South Korea to Japan in 1949. He participated in antigovernment activities occurred in Jeju Island to block the national division between the south and the north after the liberation in 1945, the so-called 4.3 incident. Besides, he was having conflict with the organization of North Korea at that time because it required a doctrinaire belief and creation in Korean. Kim was writing poems in Japanese and pursued the life of existence as a Korean-Japanese. Therefore, he decided to remain in Japan instead of returning to North Korea. Of course, he could not return to South Korea because he was a refugee. Kim imagined in Niigata, the place located in an extension of the 38th parallel and the spot of national division. He could not cross the division line when he was in his home country, but he could do it in Niigata through imagination. The life as a Korean-Japanese makes it possible. 'Zainichi', which means living in Japan, has been recognized as a worse situation compared to living in Korea. However, Kim changed his way of thinking. Zainichi can embrace South Korea, North Korea, and Japan. This is the very reason why he lives there as a Korean-Japanese. His thought like this is well expressed by symbolic representations and metamorphose as well as the imagination of spatial extension.
