산채식물인 영아자(Horned Rampion ; Phyteuma japonicum Miq.)의 영양학적인 가치를 평가코져 야생 및 평지재배 시료를 잎과 줄기로 구분하여 일반성분, 비타민 C, 유리당, 무기물, 핵산관련물질, 구성 아미노산 및 유리아미노산을 분석하였다. 야생과 재배 영아자의 회분은 1.2∼2.7%의 범위였고, 조지방과 조단백질은 재배시료가 조섬유는 야생시료에서 더 높은 함량으로 정량되었고, 전당은 두 시료간에 대차를 보이지 않았다. 비타민 C는 줄기보다는 잎에서 재배시료보다는 야생시료에서 더 높게 정량되었다. 유리당은 야생 및 재배시료 모두 glucose, frucose 및 sucrose가 잎보다 줄기에서 높게 정량되었다. 무기물은 총 9종이 분석되었는데 이중 칼슘의 함량이 가장 높아 재배시료의 경우 잎은 34374.0㎎/㎏, 즐기는 9584.1㎎/㎏였고, 그 다음으로 칼륨, 마그네슘의 순으로 많았으며, 야생시료도 비슷한 경향을 보였다. 핵산 관련물질은 CMP, UMP, IMP, AMP 및 hypoxanthine이 동정되었는데 잎과 줄기 모두 야생시료에서는 hypoxanthine이, 재배시료에서는 AMP가 월등히 높게 정량되었다. 구성아미노산은 총 17종으로 야생시료에서는 glutamic acid, 재배시료는 잎의 경우 aspartic acid, 줄기의 경우 glutamic acid의 함량이 가장 많았다. 유리아미노산은 총 29종이 동정되었고 야생시료의 잎에서는 glutamic acid, 줄기에서는 γ-aminoisobutyric acid, 재배시료의 줄기에서는 asparagine이 가장 높은 함량으로 정량되었다. This research is to establish the basic data of the nutritive value and improve our diet. In the part of th leaf and stem of the wild cultivated horned rampion(Phyteuma japonicum Mig), the components such as chemical composition, vitamin C, free sugar, mineral, nucleotide and its related compounds, composition and free amino acid were analyzed one after another. Content of the crude lipids and proteins was determined much higher in its wildness than in its cultivated horned rampion ; while, that of carbohydrates was higher in the former than in the latter. The content of vitamin C was retained higher in the leaf than in the stem horned rampion. And the content of calcium among the detected minerals was outstanding in all of the samples collected, and potassium and magnesium was the next ones in its order. The main components of free sugars in both the wild and cultivated horned rampion were glucose and fructose, and their content was higher in the stem than in the leaf. Nucleotide and its related compounds were identified with 5 kinds of nuciotides such as CMP, UMP, IMP, AMP and hypoxanthine(Hx), and the content of Hx and AMP was the highest in the wild and cultivated samples, respcetively. In the composition amino acid of the wild horned rampion, glutamic acid, aspartic acid and phenylalanine was outstandingly abundant; while, such amino acid as methionine and proline was small and besides cysteine couldn't be detected in the stem. Total amounts of composition amino acid in the leaf was 2118.0 and 1120.1㎎% in the wild and cultivated sample, respectively. In the free amino acid of horned rampion, the total amount ranged from 8.5 to 50.1㎎%, which were lower level than that of composition amino acid. But the number of free amino acid was 29 kinds, which was bigger in its number than of composition amino acid detected 17 kinds.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

The objectives of this study are to evaluate the pH neutralization and NO_(3)^(-), SO_(4)^(2-) adsorption according to the quantity of acid rain, particle diameter and packing height of oyster shells. Acid rain is mainly of anthropogenic origin due to the strong presence of SO_(2) and NOx gases in the atmosphere. Acid rain causes environmental damages, such as lake acidification, negative effects on the vegetation, in particular forests, changes in the chemical composition of solids and in metal mobility. Neutralization of artificial acid rain was enhanced by smaller particle diameter of powdered oyster shells and larger reaction area of packed column. At the initial 12 hours of reaction time, the pH of acid rain increased rapidly. pH neutralization was appeared the highest at the 48 hours of reaction time. The removal of NO_(3)^(-) was observed and the R3 reactor showed highest efficiency of 27.8%. But, SO_(4)^(2-) removal did not observed in this study.

This study was conducted to develop a simple selection method for herbicide-resistance weeds. Two methods, designated "seedling method" and "stem node method" were employed for screening of barnyardgrass against propanil and butachlor. In the seedling method, shoot and root growth of barnyardgrass were significantly inhibited at quarter of the recommended herbicide rate, while in the stem node method, the similar inhibition was obtained at half of the recommended rate. Thus, it was concluded that the seedling method is more simple and quick method to evaluate response of barnyardgrass to propanil and butachlor compared to stem node method.

This study was performed to investigate the possible role of oxyhemoglobin in the metabolic activation of benzene, styrene and TCE by observing the difference of the SCE frequency between isolated lymphocyte and whole blood lymphocyte cultures exposed to these chemicals. Isolated lymphocyte and fresh heparinized peripheral whole blood samples from a healthy donor(male, smoker) were cultured in the phytohaemagglutinin stimulated culture media for 72 hours. The cells were treated with 100, 300, 1000, 3000 μM benzene, 250, 500, 100, 2000 μM styrene or TCE respectively. Slides were stained with Giemsa's solution for SCE. SCE was analyzed for each subject from coded slides by one researcher. The results were as follows : 1.The frequency of SCE increased dose-dependently with concentration of benzene in isolated lymphocyte and whole blood lymphocyte cultures, however there were no significance. There was no significant difference of SCE frequency between isolated lymphocyte and whole blood lymphocyte cultures. 2.The frequency of SCE in whole blood exposed to sytrene significantly increased in dose-dependant relationship, but not in isolated lymphocyte. The difference of SCE frequency between isolated lymphocyte and whole blood lymphocyte of 2000μM styrene exposure was marginally significant(P=0.0540). 3.In TCE, the frequency of SCE did not increase at any concentration used in this study of isolated lymphocyte and whole blood lymphocyte. Above results suggested that oxyhemoglobin in erythrocytes play an important role in the metabolic activation of styrene but not in benzene or TCE. Key Words : Benzene, Styrene, Trichloroethylene, Sister chromatid exchange, Metabolic activation, Oxyhemoglobin

The purpose of this thesis is to show the actural and present status of the study on old documents owned by Chonbuk province and make a few suggestions about how to make use of them. Old documents are valuable not only as historial materials themselves, but as materials for cultural use as to a study on Korean history. That's why we should collect, document, and preserve the old documents being lost through modernization and industrialization. This thesis consists of two categories. One category is about the present status of the researching and documenting of old documents designated as cultural assests and those which are not. In case of the old ducuments not designated as culturas assets, the status of documenting and researching using old documents is broken into parts according to the places having them. The other is about the ways of aplication using old documents. The way how to store old documents in the computer is presented, including methodology of the regional history and the way of developing th regional culture contents using who's who or a gazetter. The materials used here come from old documents in Iksan region conducted by Iksan Historical Materia! Is Committee.(益山史料조調査委員會) There are 695 old documents designated as cultural assets including those designated as cultural assets by Chonbuk province itself, and 31,575 old documents not designated as cultural assets in Chonbuk. There are also approximately 2,663 old documents belonging to each individual, which are divided into the documents related to a state examination and a government post (42%), a etition and a lawsuit (19%), a family register (19%), and a personal property (14%). The amount of old documents owned by each museum account for more than 90% of the documents belonging to Chonbuk province, and, especially, the Museum of Chonbuk National University has about 18,000 old documents accounting for 57%. Most of the old documents carried in literature are no more than an introduction toan event or a person and they are not fully interpreted or documented. The National History Compilation Committee has comparatively carried out research on historical materials about Iksan in detail by adding images and detailed lists. Also, Museum of Chonbuk National University ha published books about old documents. In addition, of the writings using old documents in Chonbuk province, those referring to Buan Kim's documents(扶安金氏古文書) of the families from the same clan account for the most However, these are likely to change because a research and a study on old documents being underway are not included. Lastly, these findings are based on the condition of the r! esearch and study conducted on September, 2004.

본 연구는 부산지역의 주요기업 변화를 살펴보기 위해 매출액 기준 전국 상위 1,000대 기업에 속하는 부산기업을 조사하여 비교분석을 실시하였다. 분석결과 2005년에 전국 1,000대 기업 중 46개 기업이 부산에 소재하였는데, 2019년에는 12 개가 줄어든 34개 기업만이 전국 1,000대 기업에 포함되었다. 또한, 전국 상위 1,000대 기업의 매출액 기준으로 부산지역 기업의 매출액 비중은 2005년 1.6%에서 2019년 1.4%로 줄어든 것으 로 나타났다. 이는 수도권 집중현상이 점차 강화되고 있기 때문이다. 한편, 부산지역 매출액 기준 상위 10대 기업은 많은 변화가 있었는데, 2005년 상위 10대 기업 중 2019년에도 상위 10대 기 업에 포함된 기업은 ㈜한진중공업, 르노삼성자동차(주), ㈜부산은행, ㈜서원유통 등 4개뿐인 것 으로 나타났다. 통계적 인과 관계는 확정할 수 없으나 지역 대기업의 쇠퇴 및 유출과 지역의 쇠퇴가 동시에 이루어지고 있어 지역 경제의 침체와 대기업의 쇠퇴 및 유출이 상당한 관계가 있음을 유추해 볼 수 있다. 특히 2011년 이후 지역 주력 제조업 기업들이 1000대 기업 진입에 실패하였다는 점을 주목해 볼 필요가 있다. 지역 제조업 대기업의 이탈 또는 쇠퇴는 지역 생산성 하락에 영향을 미 쳤을 가능성이 높고, 낮아진 지역 산업 생산성이 지역 경제성장률 둔화에도 영향을 미칠 가능성 이 있다. 따라서 지역의 경제활력 저하 문제를 제고하기 위해서는 지역 산업구조 개편 문제와 생 산성 향상 방안에 대한 고민이 필요하다.

The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.
