Purpose: The purpose of this study was to investigate the effect of the intensity of microcurrent stimulation (with currents of 50 ${\mu}A$, 100 ${\mu}A$ and 300 ${\mu}A$ using a pulse frequency of 5 pps) on wound healing in rats. Methods: Sixty male Korean rats were randomly divided into four groups of 15 rats that were subjected to four different treatment protocols (control group, no treatment; experimental groups, treated with currents of 50 ${\mu}A$, 100 ${\mu}A$ or 300 ${\mu}A$). An experimental 20 mm linear wound was made in each animal and all animals in the experimental groups received microcurrent stimulation once a day for 20 minutes until the day of sacrifice on day 1, day 3 and day 6. An optical microscope was used to determine any histological changes. Results: The experimental results were as follows. 1. In an examination with the naked eye, all groups showed similar changes until the first day. However, from the third day, a little intercellular fluid soaked through wound region in the control group rats. In the experimental group animals, little intercellular fluid soaked through wound region, and swelling and redness did not appear, from the third day. 2. In an examination with histological evaluation, more significant changes were observed in all of the experimental group rats than the control group animals. Especially, a stimulation intensity of 50 ${\mu}A$ caused a more significant effect than the use of the other intensities by day 6 of wound healing. In addition, rapid recovery was observed. Conclusion: It was determined that microcurrent stimulation had a positive effect on wound healing. A stimulation intensity of 50 ${\mu}A$ was more effective than the other intensities (100 ${\mu}A$ and 300 ${\mu}A$) utilized for wound healing. Furthermore, low-intensity microcurrent stimulation was more effective for the purpose of wound healing.

현재 우리나라는 수환경은 갈수록 열악해지고 있으며, 환경시설 확충으로 점오염원의 배출량은 감소하는 것에 비해 비점오염원의 관리는 여전히 미흡하다. 따라서 수질개선을 위해서는 오염원의 상당부분을 차지하고 있는 비점오염원의 관리가 필요한 실정이다. 비점오염원은 점오염원과 달리 일정한 배출구를 갖지 않으므로 비점오염에 대한 체계적인 관리가 무엇보다 중요하며 유출특성을 파악하여 오염원의 발생을 근본적으로 차단하고 기술적인 대책과 제도적 대책이 마련되어야 한다. 본 연구는 비점오염 물질의 배출특성을 예측하고, 수질개선 및 환경개선을 위한 비점오염부하평가를 실시하고자 만경강에 위치한 제2소양교 지점에서 2010년 10월~2012년 6월까지 수질·수문 모니터링을 실시하여 체계적인 비점오염관리 대책마련을 위해 필요한 오염물질의 유출특성을 분석하였다. 연구유역은 전라북도 전주시 완주군 용진면 상운리에 위치한 만경강 제2소양교 유역이다. 총 유역면적은 14,851 ㏊이고, 인구는 61,617명이 거주하고 있는 것으로 조사되었다. 연구기간동안 총 강우량은 1956.9 ㎜ 이었으며, 유량은 0.12~21.02 ㎥/s의 범위로 평균 2.28 ㎥/s로 나타났다. 대상유역의 수질특성을 분석하기 위하여 월 1회 채수를 실시하여 분석하였다. 그 결과 Tot-N의 농도는 1.85~5.79㎎/L의 범위로 평균 3.90 ㎎/L로 나타났고, T-P의 농도는 0.01~0.12 ㎎/L의 범위로 평균 0.05 ㎎/L로 나타났다. SS는 29.5~163.5 ㎎/L의 범위로 평균 90.30㎎/L, BOD는 0.7~2.8 ㎎/L의 범위로 평균 1.45㎎/L로 나타났다. 연구기간 중 영양염류의 유출부하량을 산정한 결과 Tot-N은 45.86 ㎏/㏊, Tot-P는 0.35 ㎏/㏊로 각각 산정되었으며, 이중 강우기의 유출부하량이 전체의 70% 이상을 차지하고 있는 것으로 나타났다. 이와 같은 분석결과로 볼 때 강우사상과 더불어 유출량이 증가하는 7월과 8월에 집중되는 오염물질의 수계유입을 차단하기 위한 처리시설 도입과 제도적 방안이 마련되어야 하며, 동 기간 유출특성에 대한 지속적인 연구와 관리가 필요한 것으로 판단된다.

대중소설론의 변천과 의의 연구

오혜진(Oh Hye-jin) 우리문학회 2007 우리文學硏究 Vol.0 No.22

우리나라에 대중소설이 등장한 시점은 보는 시각에 따라 다르겠지만 필자는 대중소설이 활성화된 시기를 1930년대로 잡아 보았다. 1920년대 말부터 대중소설에 대한 논의들이 주로 카프 쪽에서부터 전개되었는데, 이 논의들은 이후의 대중소설에 관한 부정적인 입장과는 다른 측면을 보인다. 1930년대 들어오면서 주로 신문연재소설을 통해 대중소설이 확산되었고, 이에 따른 논의들이 임화, 이원조, 김남천, 안회남, 윤백남 등에 의해 구체화되었다. 1930년대 김기진에 의해 촉발된 대중소설에 관한 논의들은 임화와 김남천의 장편 및 대중소설과 관련된 평론들로 확대된다. 소설사적으로 보았을 때 최초로 소설론에 대한 관심을 집중시켰던 촉발점이 되기도 하였다. 비록 당대적인 현실 속에서 최선이 아닌 차선으로써 대중소설을 분석하고 비판하였지만 대중소설에 대한 관심과 아울러 대중을 '지향'하는 문학으로의 의식 변화는 매우 중요한 의미 지점이다. 비교적 활발하게 진행되던 대중소설 논의들이 해방 이후에 와서는 작가들에 의해 그 명맥을 유지한다. 김내성, 방인근, 정비석 등 대중소설작가들은 자신들의 작품에 대한 옹호와 아울러 대중소설에 대해 좀더 세부적이고 자세한 내용과 형식들을 짚어나간다. 이러한 논의들에 의해 대중소설에 대한 부정적 측면을 상당 부분 불식하는데 성공하였다고 볼 수 있고, 또 대중소설에 대한 용어도 우리 소설계에 정착시키는데 공헌하였다. 대중소설은 1970년대에 와서야 비평가들의 관심의 대상이 된다. 대중소설에 관해 비판적인 시각을 견지한 평자들로는 최일수, 김우종, 윤재근 등을 꼽을 수 있다. 이들은 통속성이나 상업성, 성적 묘사의 과도함등을 문제점으로 지적하면서 급속히 확산되는 대중소설에 대해 우려를 표명한다. 문제는 어째서 대중소설이 인기를 끌고 있고, 그 원인은 무엇인가 하는 상황적 접근보다는 부정적 측면만을 표면에 부각시킨다. 대중소설을 새로운 문학의 가능성으로 보는 시각은 김병익이나 김현, 오생근과 같은 평자들에 의해서이다. 김병익은 대중소설의 미학적 형상화와 도시적 감수성을 높이 사면서 그 가능성을 타진했고, 오생근과 김현은 대중문화에 대해 열린 시각을 요구했다. 리얼리즘 소설에 대한 시대적 경도에 어느 정도 거리를 두고 있었던 이들은 대중소설이 가지는 언어적 감수성과 미학적 근거들을 찾기 위해 노력을 기울였고, 문학의 엄숙함에 의문을 던졌다. Since the end of 1920s, discussions on popular novel has been led mostly by KAPF, which showed different aspects from those negative views on popular novel thereafter. Since after 1930s, popular novel has expanded mainly through serial publication on newspapers, and discussions on popular novel were concretized by Im, Hwa, Lee, Won-Jo, Kim, Nam-Cheon, Ahn, Hoe-Nam, and Yoon, Baek-Nam. The relatively active discussions on popular novel survived by writers after 1945 Liberation. Writers of popular novel, such as Kim, Nae-Seong, Bang, In-Keun, Jeong, Bi-Seok and others, held on to the value of their own work as well as examined more detailed and up-close content and form of popular novel. It is believed that, thanks to such discussions, a considerable amount of negative aspects on popular novel has been overcome, and that the very term of popular novel has settled in Korean novel circle. Only early in the 1970s did popular novel become the subject of interest by critics. Critics who upheld the critical view on popular novel at the time were Choi, Il-Su, Kim, Woo-Jong, and Yoon, Jae-Keun. Pointing to the problems of popularity, commercialism, excessive suggestiveness, they showed concern about widespread popular novel. Views on popular novel as a new possibility of literature have been taken by such as Kim,Byung-Ik, Kim, Hyun, or Oh, Saeng-Keun. While acclaiming the rural sentiment and aesthetic realization of popular novel, Kim, Byung-Ik sought its possibilities, and Oh, Saeng-Keun, and Kim, Hyun requested open views toward popular culture.

1930년대 아동문학의 전개

오혜진(Oh Hye-jin) 중앙어문학회 2006 語文論集 Vol.34 No.-

To properly understand children’s literature, this study examines various cultural and historical changes that influenced the genre in the 1930s. The works of writers Lee Ju Hong, Lee Tae Jun, and Hyeon Deok are analyzed, as well as social and cultural variables that provide the background to the advent of such literary works. In terms of perspective and treatment, children's literature in the 1930s differed from those exemplified by Bang Jeong Hwan’s works in the early 1920s. Such difference is caused by the influence of the Korean Artists of Proletarian Federation (KAPF) and its criticism on 'Donshimcheonsajeui', as well as by social and cultural changes surrounding children's literature during that period. The external conditions include the presentation of realistic and active imagery in KAPF's children's literature, which are based on proletarian agenda, the relation with Japanese literature, and the flourishing publishing industry of children's books and magazines. By the late 1930s, such activities were under strong pressure from factors such as the Japanese colonial policy and the sudden changes in the educational environment. The rigid suppression and the political situation when the war broke out further overshadowed children's literature of that period. The works of Lee Ju Hong, Lee Tae June and Hyeon Deok show that they yielded to the pressure and accepted their situation. In the early 1930s, when KAFP was at its peak, Lee Ju Hong’s works were marked with their realistic and concrete depiction of the child’s truths. However, when the KAPF began to disintegrate, his works dulled and his stories focused merely on fun and humor. Lee Tae June, whose works were known for their depiction of children’s simple and innocent curiosity and interest in nature, was an outstanding writer in the genre in the 1930s. Lee Tae June’s writing was already fully matured by the titre Hyeon Deok emerged in the late 1930s. Hyeon Deok was a writer of high principles who described the changes in childhood life in the late 1930s amid Japanese suppression. Noma depicted archetypal childhood reality, which reflects the living situation of that period. Of course, it was difficult for him to describe the real situations of his time. However, it is meaningful and significant for him to vividly describe the child’s living conditions despite Japanese oppression. Although such problems were not exclusive to the authors mentioned, the fairy tales that served as metaphor of real life and the realistic children's novels that were popular throughout the 1930s had their own limits, considering that such stories lacked in fantasy and imagination, which are necessary elements in children's literature. It is also hard to find evidence that such children's works in the 1930s pursued the aesthetic form or experimental deviation. The imagined reality is not just in reference to escapism. Dream and imagination give children the power to overcome anxiety and panic and help them to gain maturity. Under the influence of Japanese literature, and in the face of sudden modernization and the arrival of national independence, it may not have been possible for children’s literature to establish itself in that era. That is the reason the exciting elements of sphere of fantasy and imagination, which are important aspects of children's literature, were absent in those works, resulting in lame children's stories. The development of children's literature toward realism was not unavoidable because of the Korean War and other political turmoil that ensued. As a result, children’s literature in the 1930s was marked with limited discourse and lack of imagination.

계몽과 낭만의 소통, 역사 추리소설로 거듭나다

Recently our culture and literature spread out ‘faction’, among the rest ‘Historical- Mystery’ look better. That is the third reason for faction trend. First, a change of history direction flow post-modern and microscopic analysis. And that many public history books are printed or plenty of history dramas and cinemas are maid by clture area. Second it finds inspiration from faction trend of England and U.S.A. Third clture area increase concern about mystery-narrative. Lee jung-myung and Kim da-eun's novels distinguish the third tendency. Two novels are historical- mystery that concerned about murders realated to King Sejong as hero as and Hanguel. Also there show enlightenment, roman and new nationalism.

잎이 강건하고 화색이 엷은 좀비비추 ‘청나래’ 육성

We report a technique for obtaining seeds of ‘Cheongnarae’ (a variety of Hosta minor cultivated at the Korea National Arboretum in 2019) by artificial crossing of H. minor, collected from Jeju Island, as the female parent and H. minor ‘Krossa Regal’, cultivated outside Korea, as the male parent. Among the individuals obtained after sowing, those that showed different morphological characteristics, such as leaf shape and color, were selected. Among these individuals, those with thick leaves and light-colored flowers were further selected. Vegetative propagation and cultivation steps were repeated for evaluation of the characteristics. ‘Cheongnarae’ has relatively thicker leaves and a darker color (RHS 137A) than the control variety ‘Black Hills’ and has wings at the point where the petiole meets the leaf blade. The shape of the leaf blade edge is clearly sinuous, and the flower color is close to white (White N155B). ‘Cheongnarae’ cultivated in this way can be used for pot plant or gardening.
