The osmolarity of a medium that is commonly used for in vitro culture (IVC) of oocytes and embryos is lower than that of oviductal fluid in pigs. In vivo oocytes and embryos can resist high osmolarities to some extent due to the presence of organic osmolytes such as glycine and alanine. These amino acids act as a protective shield to maintain the shape and viability in high osmotic environments. The aim of this study was to determine the effects of glycine or/and alanine in medium with two different osmolarities (280 and 320 mOsm) during IVC on embryonic development after parthenogenesis (PA) and somatic cell nuclear transfer (SCNT) in pigs. To this end, IVC was divided into two stages; the 0-2 and 3-7 days of IVC. In each stage, embryos were cultured in medium with 280, 320, or 360 mOsm and their combinations with or without glycine or/and alanine according to the experimental design. Treatment groups were termed as, for example, "T(osmolarity of a medium used in 0-2 days of IVC)-(osmolarity of a medium used in 3-7 days of IVC)" T280-280 was served as control. When PA embryos were cultured in medium with various osmolarities, T320-280 showed a significantly higher blastocyst formation (29.0%) than control (22.2%) and T360-360 groups (6.9%). Glycine treatment in T320-280 significantly increased blastocyst formation (50.4%) compared to T320-280 only (36.5%) while no synergistic was observed after treatment with glycine and alanine together in T320-280 (45.7%). In contrast to PA embryonic development, the stimulating effect by the culture in T320-280 was not observed in SCNT blastocyst development (27.6% and 23.7% in T280-280 and T320-280, respectively) whereas the number of inner cell mass cells was significantly increased in T320-280 (6.1 cells vs. 9.6 cells). Glycine treatment significantly improved blastocyst formation of SCNT embryos in both T280-280 (27.6% vs. 38.0%) and T320-280 (23.7% vs. 35.3%). Our results demonstrate that IVC in T320-280 and treatment with glycine improves blastocyst formation of PA and SCNT embryos in pigs.

The purpose of this study was to identify the causal relationships among self management, performance and leadership of Gymnastic coach’s. The instrument for data collection was a questionnaire in which self management as identified by Hu(2003) and performance by An(2002) and leadership as identified by Wright(1996). 280 subjected were selected from Gymnastic teams in Korea by the cluster sampling method. Among these selected subject, 268 responded, and data analyses consisted of employing factor analysis, correlation and covariance structure analysis using SPSS/PC+ 15.0 and AMOS 7.0. The following results were obtained: The relationships among self management, performance and leadership of Gymnastic coach’s were the causal relation. First, leadership statistically and significantly influences self management. Second, self management statistically and significantly influences performance.
스마트폰 디스플레이 및 터치 User Interface의 최신 기술 동향에 대한 분석
이주형 에스케이텔레콤 (주) 2011 Telecommunications Review Vol.21 No.2
본 논문에서는 스마트폰에 채용되고 있는 최신 디스플레이 및 터치 기술의 동향을 정리, 분석하고 있다. 스마트폰에 채용되는 디스플레이는 크게 LCD와 OLED로 양분되며 모두 각각이 갖는 기술적 장점을 활용하여 고해상도, 고화질, 슬림화, 저소비전력의 방향으로 발전하고 있다. 사용자 인터페이스의 대표적 기술인 터치는 멀티 터치 기술을 기본적으로 채용하고 있으며 향후 대형화, 고감도화를 통해 스타일러스 펜 터치까지 가능할 것으로 기대된다. 또한 터치센서와 디스플레이와의 융·복합화 형태인 내장형 TSP (Touch Screen Panel) 기술이 기구적, 광학적 장점에 힘입어향후 주목 받을 것으로 예상된다.

Kye Yongmook wrote 45 short stories from 1924 to 1950. His fiction writing training started with the reception of aestheticism, technicalism and nihilism through the literary journal The Creation. He clung to technicalism and nihilism to the end, while seeking after aestheticism, and realism from time to time. He viewed the lives of all the people of his days as tragic, and tried to depict those who fell into tragic plights in all his works. The whole period of his creative life can be divided into three: first, from late 1920s to early 1930s, second, from late 1930s to early 1940s and third, after the National Liberation. In the first period, he pursued literary realism in his stories, where he depicted the farmers who fell into tragic situations because of the barrier of class distinctions. In the second period, his works were oriented towards aestheticism, portraying diverse people who fell into tragic plights because of various obstacles including diseases. In the third period, he came back to realism, and described the national tragedy caused by the contradictions after the Liberation. But there is no character who gets out of the tragic situation in his stories, as he/she does not analyse its causes, nor try to find a way out, nor fight actively to escape from it. It resulted from the facts that Kye Yongmook, the writer, couldn't recognize the reality of his days deeply, and lacked in the unique insight of life. Consequently, Kye Yongmook stopped writing fiction at the early age of 46 in spite of good health without leaving many good works, for he didn't have an eye for the national realities and lives of the people, and couldn't develop new sources for literary creation. Thanks to the two of his works, “Adada, the Idiot” and “Counting Stars”, which can be evaluated as well written, he has been regarded as a writer who should be recorded in the modern fiction history of Korea, though he cannot belong to the main writers' group.
