조봉오, 이인녕, 정균근, 장창현. 좌업 시간과 알코올 섭취가 30대 남자 사무직 근로자의 혈압과 혈관탄성에 미치는 영향. 운동과학, 제23권 3호, 241-248, 2014. 본 연구의 목적은 일과 중 대부분을 좌업근무 형태로 업무를 수행하고, 스트레스로 인해 음주가 잦고, 운동이 부족한 30대 남자 사무직 음주자 15명을 대상으로 좌업 시간과 알코올 섭취가 혈압과 혈관탄성에 미치는 영향을 분석하여 사무직 근로자에게 건강관리에 필요한 정보를 제공하는데 있다. S대학 운동 생리학 실험실에서 사전 인적 사항과 설문을 작성하고, 신장, 체중, 채혈, 혈압, 혈관탄성, BMI를 측정하였다. 알코올 섭취 횟수, 섭취량, 좌업 시간, 그리고 음주 섭취 전과 후 및 시간대별 (10분, 40분, 60분) 혈압과 혈관탄성의 변화를 측정 분석한 결과를 요약하면 다음과 같다. 1) 평균 좌업시간이 9.87시간, 음주횟수 및 음주량은 월 평균 9.13회와 12.47잔 이였다. 2) 알코올 섭취횟수 및 섭취량에 따른 BMI, TC, LDL-C, HDL-C, 혈압과 혈관탄성 비교에서 알코올 섭취횟수에서 좌상지 혈관탄성은 통계적으로 유의한 차이를 나타냈다(p<.05). 3) 알코올 섭취 전, 후 비교 분석 결과 우상지와 좌상지의 혈관탄성에서 통계적으로 유의한 차이가 나타났다(p<.05). 4) 알코올 섭취 후 시간대별 우상지 혈관탄성은 통계적으로 유의한 차이를 나타냈다(p<.05). 이상의 결과를 종합해 볼 때, 좌업 시간이 혈압과 혈관탄성에 미치는 영향은 통계적으로 유의하게 나타나지 않았고, 알코올 섭취는 혈관탄성에 통계적으로 유의한 차이를 나타냄을 알 수 있었다. 따라서 이는 직장생활의 스트레스를 음주로 해소하는 경향이 있음을 보여주며 건강에 부정적인 영향을 주고 있음을 알 수 있었다. 또한, 신체가 음주에 적응되어 실험 시 섭취한 적은 양(1/2병)은 1회 12.47잔에 비해 혈압과 혈관탄성에 큰 영향을 미치지 못한 것으로 사료된다. Cho, Bong-Oh, Lee, In-Yeong, Jeong, Gyun-Geun, Jang, Chang-Hyun. Effects of Sedentary Occupation Time and Alcohol Intake on Blood Pressure and Vascular Compliance in 30s Male White-Collar Workers. Exercise Science, 23(3): 241-248. 2014. The purpose of this study was to examine effects of duration of sedentary office work and alcohol intake on blood pressure and vascular compliance in male subjects who were office workers aged between 30 to 39 and frequently drink alcoholic beverages to cope with their stress without exercising for health. The study was to provide health-related information necessary for white-collar workers. We collected data of demographic information, height, weight, blood sample, blood pressure, vascular compliance, and BMI from 15 subjects in S University`s Exercise Physiology Laboratory, and analyzed the frequency and amount of alcohol intake, duration of sedentary work, and changes in blood pressure and vascular compliance at diffident time points (10, 40, and 60 minutes post drinking) from baseline. I t was found that the average time of sedentary work was 9.87 hours, drinking 9.13 times a month on average, 12.47 glasses of alcohol beverages per drink. In comparison of BMI, TC, LDL-C, HDL-C, blood pressure and vascular compliance upon the frequency and amount of alcohol intake, the upper left limb`s vascular compliance had a statistically significant difference (p<.05). In the result of the comparative analysis of pre-and post-drinking, vascular compliance was significantly different in the upper right and left limbs (p<.05). Vascular compliance in the upper right limb after drinking significantly changed (p<.05). As a result, the duration of sedentary work had no statistically significant difference in blood pressure and vascular compliance. T he vascular compliance after drinking h ad a statistically significant difference. This suggested that the result was an index that shows the trend of the office workers releasing their work stress by drinking alcoholic beverages, and that drinking had negative impacts on them. In addition, a small amount of intake (a half bottle) at the test time, after the body was adjusted to drinking, compared with 12.47 glasses per intake, had no great impacts on blood pressure and vascular compliance.

Eight monitoring stations in the Yeosu National Industrial Complex will determine the concentration of air pollutants measured every hour in 2019, analyze what factors affect them, and how they correlate with the air pollutant measurements. Six air pollutants (SO2, NO2, O3, CO, PM-10 and PM-2.5) measured at eight monitoring stations around Yeosu National Industrial Complex (Seogang-dong, Wolnae-dong, Munsu-dong, Yeocheon-dong, Deokchung-dong, Hwayang-myeon, Yulchon-myeon, Samil-dong) the measurement data for each hour of the year were downloaded to analyze the concentration by weather condition, time zone, season, separation distance from Yeosu Industrial Complex, and separation distance from Gwangyang Industrial Complex. SO2, NO2, and CO concentrations were significantly higher in winter, significantly lower in summer, and O3, PM-10, and PM-2.5 concentrations were significantly higher in spring. SO2, CO, PM-10, and PM-2.5 concentrations were significantly higher between 10 a.m. and 12 p.m., NO2 concentrations were significantly higher between 7 a.m. and 9 a.m., and O3 concentrations were significantly higher between 13 p.m. and 15 p.m.(p<0.001). The concentration of air pollutants (SO2, NO2, CO, PM-10, PM-2.5) excluding O3 was found to have a negative (-) correlation with weather condition, and in the case of O3, it was found to have a positive (+) correlation with PM-10, PM-2.5, temperature and wind speed. It was confirmed that the concentration of air pollutants emitted from the Yeosu National Industrial Complex differs depending on the season, time and distance to the industrial complex. This study aims to establish measures to minimize health damage to residents living relatively close to the industrial complex and contribute to the establishment of management and response measures according to the properties of substances to reduce the concentration of air pollutants in the future.

미생물을 이용한 Gellan Gum 생성의 Kinetic에 관한 연구

金春永,鄭奉佑,張光燁,李銀美 全北大學校 1992 論文集 Vol.34 No.-

Polysaccharides produced microbially, have shown themselves to be commercially significant. The reasons for the commercial exploitation of these microbial polysaccharides is because of their unique physical and consistant chemical properties and regularity of supply. Gellan gum is a recently discovered extracellular polysaccaride. This is an anionic heteropolysaccharide that forms viscous solutions and can under certain conditions, form thermoreversible gels with characteristics similar to those formed by both carrigeenan and agar. The aspect of Gellan gum produced by Pseudomonas elodea were investigated under various concentration of carbon sources and nitrogen sources. Sucrose and glucose are used as carbon source, and Bacto-peptone, Promosoy and (NH_4)_2SO_4 are used as nitrogen source. The maximum Gellan gum production was obtained in the culture medium 30.0g/L glucose, 0.6g/L Promosoy at pH 6.6, 37℃. The molecular weight of Gellan gum was 5 × 10 exp (5) which was determined by gel permeation chromatography.

논 잡초 올챙이고랭이의 화학적 방제

노영덕,이민호,이봉근 경희대학교식량자원개발연구소 2006 硏究論文集 Vol.25 No.-

우리나라의 벼 재배지역에서 최근 그 발생량이 증가 하여, 문제잡초로 되고 있는 올챙이고래이의 효과적인 방제를 위하여, 토양처리 및 경엽처리제초제들의 효과를 시험하였던 바, 그 결과는 다음과 같다. Sulfonylurea계 토양저리 제초제들은 Azimsulforon을 제외하고는 그 방제효과가 우수하였는데, 이들 제초제들은 올챙이고랭이 3~4엽기까지 훌륭한 방제 효과를 나타내었다. 기타 토양처리 제초제들의 경우, Simetryn을 제외하고는 그 방제효과가 미흡하거나, Pretilachlor나 Mefenacet와 같이 발아초기에만 효과가 인정되는 것들이었다. Simetryn의 경우에는 올챙이고랭이 3~4엽기 때까지 효과적인 방제가 가능하였다. 경엽처리의 경우 2,4-D나 graminicide들은 방제효과가 낮았고, Bentazone과 Bentazone 합제들은 우수한 방제효과를 나타내었다. Scirpus juncoides Roxb. is a quite recent problem paddy weed in Korea, but is rapidly wide spreading around the country, especially because it is one of the sedges which are hard to control chemically. For the reason, wide spectrum of paddy herbicides, both soil and foliar applied, were evaluated for the effective control of the problem weed. The most of the sulfonylurea herbicides tested have been effective when treated until 2 to 4 leaf stages except Azimsulfuron. In the other group of soil applied herbicides, other than sulfonylureas, only Simertryn was found effective for the control. Pretilachlor and Mefenacet were also good in the case of pre-emergence treatments, but they could not control the weeds when they were already germinated. Among the foliar applied herbicides, Bentazone and Bentazone mixed formulations appeared effective for the control of problem weed, Scripus juncoides.

황영원,김봉환,이광일,김상하 충남대학교 자연과학연구소 1993 忠南科學硏究誌 Vol.20 No.1

An operating system is program modules within a computer system that govern the control of equipment resources such as processors, main storage, secondary storages, input/output devices, and files. CNUOS is a research project on distributed operating systems being carried out at Chungnam National University. Its goal is to investigate capability-based, object oriented systems and to build a working prototype system to use and evaluate. In this system, user-level server processes provide functions that have been traditionally provided by the operating system. This approach leads to a small(hence more reliable)kernel and makes it easier to provide, modify, and test new services. In this paper, The kernel prototype of CNUOS will be proposed.

草盧 李惟泰의 詩世界

劉永奉 한국한문학회 2003 韓國漢文學硏究 Vol.0 No.31

‘忠情五賢’의 한 사람 초려는 조선 중기 ‘山林’의 중요한 구성원이다. 초려는 총 440수의 한시를 남겼는데, 이들은 近體詩의 형식으로만 이루어졌다. 초려의 시는 유배기를 중심으로 양분된다. 유배 이전에 지은 시는 193수이고, 유배 기간 에 지은 시는 모두 247수이다. 유배 이전에 지어진 시들은 濂洛風의 성격을 강하게 지니고 있다. 내용적으로 居敬存心의 진지한 학문적인 자세가 바탕이 된 시들이다. 유배기의 시들은 連作化라는 특징을 지니고 있다. 내용적으로는 家統의 유지라는 현실적인 고민 아래 지어진 시들과 초려 개인의 내밀한 심상이 노출된 시들로 구분이 된다. 사림학자들의 시들과 크게 다른 초려 시만의 두가 내용상의 특징이라고 하겠다. Choryo Lee yoo-tae(AD 1607~1684) is not only one person of Chungchong-ohyun(忠情五賢) but also an important members of Sanlym(山林) in the middle of the Chosun dynasty(朝鮮). He composed a total of four hundred and forty Chinese poetry, and all of them were in the type of modern(近體詩). His Chinese poetry could be divided into two regions according as he was exiled before and after. The number of poetries written before exile was one hundred and ninety three and two hundred and forty seven poetries were written in a period of banishment. Poetries written before deportation have a strong character of Yeomrak style(濂洛風) however, their contents were on the base of sincere academic attitude as honesty (居敬存心). Poetries written in the time of exile have features of prolongation. These could be divided into two classes, and one of which was poetries written under the circumstances of realistic agony such as keeping of a family tradition and lineage. The other were poetries which his inmost thought was exposed. These two characteristics were quite different from those of other Sanlym in term of contents.

목 적 : 정 신분열병 환자의 자기만입 정도에 영향을 미치는 인구학적 변인들 및 질병연관 변인들을 규명해 보고자 하였다. 또한. 환자들의 자기만입과 병식 사이의 연관성. 자기만입과 자존심 사이의 연관성을 알아보고자 하였다. 방 법 : 정신과 의사가 병록지와 면담을 통하여 대상 정신분열병 환자들의 인구학적 변인들 및 질병연관 변인들에 관한 자료를 얻고 환자들의 병식 정도를 평가한 후, 환자들로 하여금 자기보고형의 자기만입 척도와 자존심 척도를 시행하게 하였다. 총 111명의 환자가 연구대상으로 선택되었다. 결과: . 1) 여자가 남자보다 유의하게 높은 자기만입 척도 점수를 나타내었다 2) 질병연관 변인들 중 하위집단 사이에 자기만입 척도 점수의 유의한 차이를 보이는 변은 없었다. 3) 자기만입 척도 점수와 병식 점수 사이에 유의한 상관관계가 없었다. 4) 자기만입 척도 점수와 자존심 척도 점수 사이에 유의한 역상관 관계를 보였다. 결 론 : 본 예비 연구의 결과로 보아 정신분열 병 환자의 병식이 부족한 상태에서도 자기만입이 진행될 수 있으며. 자기만입이 심할수록 환자의 자존심이 저하되는 것으로 생각된다. 또한 여자 환자들이 남자 환자들보다 자기만입에 더 취약한 것으로 생각된다. 따라서 정신분열 병 환자의 이해와 치료를 위하여 자기만입에 관한 지속적인 연구가 필요할 것으로 생각된다. objective : This study was conducted to identify demographic variables and illness related variables which may affect the severity of self-engulfment in the patients with schizophrenia. We also studied the relationship between self-engulfment and insight, and the relationship between self-engulfment and self-esteem. Methods : Data on demographic variables and illness related variables for the subjects were gathered from hospital records and clinical interviews by the psychiatrists. Degree of insight for the subjects was assessed through clinical interviews by the psychiatrists. Degree of self-engulfment and self-esteem for the subjects was assessed from the self-engulfment scale and the self-esteem scale respectively. A total of 111 patients with schizophrenia were selected for statistical analysis. Results 1) The females exhibited significantly higher scores than the males on the self-engulfment scale. 2) There was no illness related variable, which exhibited a significant difference among subgroups on the self-engulfment scale. 3) There was no significant correlation between the self-engulfment scores and the insight 4) There was a significantly inverse correlation between the self-engulfment scores and the self-esteem scores. Conclusion : The results of this preliminary study suggest that self-engulfment may develop despite lack of insight and that there was inverse relationship between self-engulfment and self-esteem in the patients with schizophrenia. It also suggests that females are more subject to self-engulfment than males. So, authors suggest that it is valuable to do further studies of self-engulfment in the patients with schizophrenia.
