Paper records were generally degraded by some factors from atmospheric environments, like temperature, relative humidity or air pollutants. In this study, the degradation behavior of paper records by single or mixed gases of NO₂, SO₂, HCHO and TVOC was evaluated. The mechanical, optical and chemical properties of 4 kinds of paper (acid and neutral-based printing paper, traditional Hanji, and filter paper) were directly and indirectly affected by gaseous harmful materials. The brightness and L<SUP>*</SUP> value in all papers were slightly increased by accelerated aging under gaseous HCHO and TVOCs, but highly decreased by conditions under gases NO₂ and SO₂. The optical properties of paper records were most vulnerable in acid-based paper and high stable in filter paper and traditional Hanji by air pollutant degradation. The aging treatments under mixed gas pollutants including NO₂ resulted in decrease of physical, mechanical and optical properties of paper, so it was supposed that the concentration of NO₂ gas would be strictly controlled for optimum indoor air quality management in domestic storage centers for paper records.

This study concentrates an the trail of the CNU(Chungnam National University) forest. The amount of use and the pattern of damage are considered, as well as the extent of environmental damage. Finally, some managerial strategies are proposed in connection with sustainable maintenance. The trail of the university forest is composed of three sections; one is the neighborhood park and the Institute of Information Technology/Communications, the second is the Institute of Information Technology/Communications and the Dormitory, and the third section is the Dormitory and the Foreign prof's Apt. The total length of the trail is 2.6km. The daily amount of use is 1,269 visitors per day. The amount of using increased three times the amount of that in 1998. This study shows the pattern of damage of the trail in the order of root-exposure, widening, rock-exposure, deepening and the divergence in the frequency of occurrence of all these factors. Environmental damage is also graded thus: grade 3 is 27.4m, grade 4 is 0.8m, grade 5 is 1.5m, and grade 6 is 0.2m. Accordingly, some managerial strategies were proposed in connection with the sustainable trail maintenance.

『포의교집(布衣交集)』에 드러나는 금기 위반의 양상과 초옥의 욕망

이소연 ( Lee So-yeon ) 한국기호학회 2017 기호학연구 Vol.52 No.-

이 글은 『포의교집』의 여주인공 초옥의 욕망에 주목하여 초옥이 금기를 위반하게 된 원인과 방식을 살펴본 것이다. 금기는 사회 체제와 질서 유지를 위한 수단으로 작용하므로 금기를 위반하는 일은 사회를 위협하는 것으로 간주되었다. 금기는 항상 인간들의 강한 욕망을 제지하고 억압한다. 따라서 인간은 금기 위반의 욕구를 가지고 있으며, 인간은 금기와 욕망 사이에서 늘 갈등한다. 초옥은 자신의 오랜 소원이던 문장 잘하는 선비로 인식한 이생을 만나 그를 욕망한다. 그녀의 욕망은 작품 속에서 뚜렷이 드러나며, 너무도 강렬하여 당대 금기를 위반하기에 이른다. 이 글에서는 먼저 초옥의 금기 위반 양상을 살펴보고, 금기 위반이 그녀의 욕망에서 비롯되었다는 점을 밝히기 위해 그레마스(Algirdas Julius Greimas)의 행위소 모형(Actantial model)을 사용하여 작품의 의미 구조를 다각적으로 분석하였다. 다음으로 인간의 욕망이 모방에서 출발한다는 르네 지라르(Rene Girard)의 이론을 통해 초옥의 욕망 또한 모방 욕망(mimetic desire)에서 비롯되었음을 밝히고자 하였다. 지금까지 초옥은 젠더와 신분을 뛰어넘어 양반과의 지기를 욕망하는 진취적 주체이자, 스스로 사랑을 찾아 나서는 주체적인 여성이란 점에서 근대적 인물로 평가되어 왔다. 그러나 지라르의 이론에 따라 초옥의 욕망을 자세하게 살펴보면, 초옥은 중세적 윤리의식에 갇혀 있는 인물이다. 초옥이 꿈꾸는 이상적인 삶의 모델이 되는 여성 모습은 유교 텍스트에서 모범적인 여성상으로 제시되고 있는 인물들이다. 초옥이 욕망하는 이상적인 삶 또한 그녀가 습득한 지식을 기반으로 하고 있기에 전근대적이다. 초옥은 하층민 출신이지만, 높은 지적 수준을 갖게 되었기에 인식과 신분적 차이에서 오는 괴리감이 존재했다. 초옥은 괴리감을 줄이고자 동경하던 상류층 여성의 삶을 모방하고자 한다. 따라서 초옥의 윤리의식도 상당 부분 남성 중심적일 수밖에 없다. 초옥은 강력한 욕망을 실현하기 위해 금기를 위반하지만, 그녀의 욕망은 남성 중심적 윤리관을 바탕으로 하고 있다. 금기와 욕망의 충돌 사이에서 궁극적으로는 욕망이 포기되고, 초옥의 금기 위반은 새로운 세계를 열어주지 못하고 비극으로 끝을 맺는다. Purpose of this paper is to identify the reason and methods she violated the taboo by closely examining the desire of Cho-ok who was a heroine in Po-Eui-Gyo-Jip. Because the taboo acted as a way to maintain social system and orders, the violation of taboo was regarded to threaten the society. Taboo always restrains and suppresses strong human desire. Therefore, human beings have the desire to violate the taboo and are always conflicted between taboo and desire. Cho-ok met and desired Lee-saeong who was her long hope and recognized as a classical scholar with good writing. Her desire appears distinctly evident in her works and it came to violate the contemporary taboo because it was too strong. In order to examine the aspects of Cho-ok’s violation of taboo and show that taboo violation came from her desire, the meaning structure of the work was analyzed in various ways using Actantial model of Algirdas Julius Greimas. Next, through Rene Girard’s theory that human desire starts from the imitation, it was tried to show that Cho-ok’s desire also came from mimetic desire. Until now, Cho-ok has been evaluated as a modern character in the aspect that she was a progressive subject and subjective female who desired the friendship with yangban(the gentry) beyond her gender and class. However, closely looking at Cho-ok’s desire according to Girard’s theory, she is a character who is trapped in the medieval ethical consciousness. The female figure which was a model of the ideal life Cho-ok was dreaming is a character who is suggested as an exemplary female image in the Confucian texts. Ideal life Cho-ok was dreaming is also old-fashioned because it is based on her knowledge she acquired. As Cho-ok could have high intellectual level even though she was from lower class, there was a sense of alienation from the difference of recognition and identity. In order to reduce the sense of alienation, Cho-ok tries to mimic the life of high class women she has been longing. Therefore, the moral consciousness of Cho-ok cannot but man-centered in most parts. Cho-ok violates the taboos to realize her strong desire, but her desire is based on a man-centered ethics. Between taboos and desire, the desire was eventually abandoned and Cho-ok’s taboo violation finally ended in tragedy without opening a new world.

To find the characteristics of stroke patients and the relation between the pathway of admission and characteristics, of the patients including general characteristics, progression of disease and subjective complaints, an analysis was made from the medical record of 291 inpatients due to stroke admitted to a oriental medicine university hospital in 1997. 1. Diagnosis categories of analyzed Patients were 50 cerebral hemorrhage and cerebral infarction. 2. Sex distribution of patients showed 125 male and 165 female and age distribution showed peak 33.7% at 60-69 year old group, 26.5% at 70-79 year old group in descending order(p<05). 3. Thirty four percent of stroke patients had family history of stroke and male showed significantly higher rate of family history of than female(p<05). 4. The type of physical constitution was classified as Tea-Eum-In(太陰人) 43,6%, So-Eum-In(少陰人) 29.9%, So-Yang-In(少陽人) 26.1%, Tea-Yang-In(太陽人) 0.3% in descending order of frequency. 5. Hypertension was the preceding condition for 36.4% of cerebral hemorrhage and 42.7% of cerebral infarction. 6. Sixty nine point four percent of the patients of the patients suffered from the stroke for the first time and 25.4% for the recurred stroke. Major subjective complaints of the patients were motor disturbance, speech difficulty and headache in descending order. 7. As the institution for medical care to this admission, 138 person(47.4%) used western type hospital or clinics, 137 persons(47.1%) passed oriental medicine clinics or hospitals, 6 persons(2.1%) used both type of western medicine and oriental medicine and 10 person(3.4%) used pharmacy folk medicine. 8. As pathway of medical care for cerebral hemorrhage 71.2% of patients used western type hospital or clinic and 26.9% used oriental type of care where as for cerebral infarction 42.3% used western type and 51.5% used oriental type. 9. While admitted to this hospital within one day after occurrence of the disease used oriental type by 87.5% and western type by 14.3%, patient admitted in one week after occurrence of the disease used western type by 66.9% and oriental type by 27.1%. The above results showed that the pathway of medical care for the stroke patients was complicated and make many problems due to delay in the arrival to medical care. So effective health care delivery system for the stroke patients must be made for more efficient medical care.

Da-Young Park,Kyung-Jin Lee,Yangkang So,Zhe Lu,Seulki Lee,Jung-Hwan Lee,Seung Han Oh,Yeon Soo Han,Doo-Byoung Oh,Youngkwan Kim,Kisung Ko 한국당과학회 2010 한국당과학회 학술대회 Vol.2010 No.1

Plant genetic engineering has led to production of plant-derived mAb (mAbP), which can provides a safe and economically effective alternative to the conventional antibody expression methods. In this study, the expression levels of mAbP SO57 with or without ER-retention peptide extensions signal (Lys-Asp-Glu-Leu; KDEL) in transgenic tobacco plants were analysed in transgenic plant. The expression levels of mAbP SO57 with KDEL were significantly higher than that without KDEL regardless of transcription level. mAbP SO57 with KDEL localized surround to the nucleus suggesting that the mAbP with KDEL is localized in ER. The mAbP without KDEL and mAbH had mainly Golgi type glycans, whereas the ER-localized mAbP with KDEL had glycan profile with both oligomannose type (47.6%) and Golgi type (52.4%). The Fc domains of both purified mAbP (with and without KDEL) and human-derived mAb (mAbH) had similar bingding activity to the Fcγ RI receptor (CD64). Both mAbP (with and without KDEL) had a shorter half-life than mAbH. However, both mAbP with and without KDEL was as effective at neutralizing activity of the rabies virus CVS-11 as the mAbH. These results suggest that ER localization of recombinant mAbP by KDEL reprograms glycosylation and enhances production of the functional antivirus therapeutic antibody in the plant.

Many efforts have been carried out to cure and treat cancer, but there are still a constant increase in death ratio due to cancer. The prevention of cancer is the most important thing because cancer is the fatal disease. There are many ways to prevent cancer, physical activity is one of them. Many studies have investigated the relationship between physical activity and cancer. The results of these studies are as follows; there is around 40-50% less chance of getting colon cancer, 30-40% for breast cancer, and 10-30% for prostate cancer. Even with all these studies it was hard to find Korean studies investigated the relationship between physical activity and cancer. The prevalence rates of cancer are hugely variable due to the difference of gender, ethics, diet habit and physical activity. So it is needed that studies should be done for each ethical group. The variation of physical activity is huge and it depends on many various factors: intensity, frequency, duration, and type. For this reason, it is hard to estimate the total physical activity accurately with large population in a long term study. The inconsistent results could be attributed, in part, to methodological issues, including crude assessment of physical activity. Therefore further studies should be performed to develope more precise methods of estimating total physical activity and investigate the relationship between physical activity and cancer for reducing cancer with Koreans.

The concept of revascularization of necrotic pulps regained interest and became an alternative conservative treatment option for young permanent teeth with immature roots. Revascularization of immature teeth with apical periodontitis depends mainly on disinfection of the canal. Since the infection of the root canal system is considered to be polymicrobial, a combination of drugs would be needed to treat the diverse flora. A triple antibiotic mixture of metronidazole, ciprofloxacin, and minocycline was used as an intracanal medicament. However, discoloration was developed after applying the triple antibiotic mixture. It is believed that the marked discoloration is related to the use of minocycline. The aim of this article was to present cases of coronal discoloration after triple antibiotic therapy in immature tooth and was treated with bleaching technique to control coronal discoloration. In conclusion, revascularization by using triple antibiotics promotes a paradigm shift in treating endodontically involved permanent teeth. However, we should understand that triple antibiotics containing minocycline induces tooth discoloration. Further research to prevent coronal discoloration should be investigated and suggested for the safe use of triple antibiotics. 괴사된 미성숙영구치의 치수치료에 있어서 치수의 재혈관화를 통해 치근단 발육 및 치근형성을 지속하려는 개념이 소개됨 으로써 현재 미성숙영구치의 치수치료의 대안으로 제시되고 있다. 이러한 치근단 염증을 가진 미성숙 영구치의 재혈관화를 위해서는 가장 중요한 것이 근관내 감염된 부분을 확실히 제거하는 살균(disinfection)이다. 근관 내 감염은 여러 세균의 복 합작용으로 일어나기 때문에 철저한 살균에 사용되는 약제의 조합은 다양한 범위의 균주를 모두 제거 가능해야한다. Metronidazole(MN), ciprofloxacin(CF), minocycline(MC)의 세 가지 복합항생제가 약제로 사용되고 있으나 이 복합항생 제 적용 후 치관변색을 일으키는 사례가 보고되고 있다. 이러한 치관변색은 항생제의 성분 중 MC에 의한 것으로 여겨지고 있으며, 본 증례에서는 복합항생제 적용에 의해 야기된 치관변색의 증례를 소개하고 이를 표백술로 처치하여 최종 수복한 증 례를 보고하였다. 복합항생제 적용을 통해 미성숙영구치의 치수치료에 새로운 패러다임을 제시한 것은 분명하지만 치관변색 등의 부작용이 있음을 인지하고 치관변색을 사전에 예방하고 최소화하기 위해 다양한 방법이 강구되어야 할 것이다.

Objective: This study was performed to investigate the relationship between practice of health promoting lifestyle and its related factors among civil servants in Gwang-Ju Metropolitan city. Methods: We enrolled 500 civil servants who worked in Gwang-Ju Metropolitan city hall by random sampling and 419 cases were analyzed. The collection of data was done by self-administered questionnaire which composed of the general characteristics, the occupational characteristics, health related activity, stress, self-efficacy and the Health Promoting Lifestyle Profiles (HPLP). We analysed the data by t-test, analysis of variance, Pearson's correlation analysis, and multiple regression analysis. Results: The mean score of HPLP was 113.6±19.8. In univariate analysis, HPLP was related to marital status, education level, business career, perceived health status, age, body mass index, stress and self-efficacy. As a result of multiple regression analysis, the statistically significant related factors with HPLP were business carrier, perceived health status, and self-efficacy. However, marital status, body mass index and stress were not statistically significant. Conclusions: We concluded that the health promoting activities were related with good subjective perception about their health status, high degree of self-efficacy and longer duration of business carrier.
