This study was carried out to obtain the basic data on salted and fermented damsel fish(Jari-Jeot), one of the important traditional marine foods in Cheju-Do. and also to seek salt lowering method for the development of a new local tourist food. The results are as follows : The best organoleptic results were obtained after 60 days' fermentation for 25.0, 12.5 and 10% of salt-added group, and around 45 days for 7.5 and 5% of salt-added group. In raw fish ingredient IMP was abundant which marked 17.7 μmole/g while in fermented fish hypoxanthine was predominant but ATP and ADP were not detected after 30 days' fermentation. Sixteen kinds of free amino acids were detected and identified in Jari-Jeot instead of 17 kinds of those in raw sample. The abundant amino acids in Jari-Jeot after 60 days' fermentation were lysine. alanine, glutamic acid, glycine and leucine, and those were consisted of approximately 60% of the total free amino acids. During fermentation the content of TMAO was decreased gradually and no TMAO was detected after 75 days' fermentation while that of TMA was increased during fermentation up to 45 days' and decreased afterwards. The fatty acid of low-salt Jari-Jeot was composed of 31.9% of saturated acids, 13.2% of monoenoic acids and 54. 9% of of polyenoic acids. While the content of EPA in polyenoic acids was 1.9%, that of DHA was 23.0%. In order to lower salt concentaration of fermented damsel fish, additon of Pediococcus halophilus culture as a starter together with 10-12.596 of salt, 4-5% of KCI, and 2% of glucose gave as good quality as traditionally made Jari-Jeot.

The effects of regular endurance exercise on superoxide dismutase and citrate synthase activity for the soleus and extensor digitorum longus muscles in rats that underwent swimming training for 12 weeks were examined. The correlation between Mn-SOD activity and citrate synyhase activity of the soleus were also examined. Sixteen male rats were randomly divided into 2 groups: SC (sedentary control group) and ET (exercise trained). The blood glucose and total cholesterol level of ET group were significantly lower than those of SC group(p<0.05). The mitochondrial citrate synthase activity of the soleus muscle for the ET group was significantly higher than those for SC rats(p<0.05). However, the correlation between citrate synthase activity and Mn-SOD activity of the soleus was very low. For the conclusion, mitochondrial antioxidant enzyme activity showed low correlation with the endurance exercise performance. However, endurance exercise showed significant improvement in the biochemical indices related aerobic performance and mitochondrial antioxidant enzyme activity.

This dessertation has dealt with the formation process of modern novels and its developing patterns in order to make the history of criticism in modern Korea straight. The following is an outline of the discussion. The theories of patriotic, enlightening novels can be devided into two parts: the reformation of novels and making the then ideology into a logic system. Those who participated in the reformation of novels insisted upon creating historical novels which should be realistic in order to overcome the situation of those days. The movement could be said to be a sort of methodology of creative writing. Through the above discussion of the theories of patriotic, enlightening novels the fact is revealed that the previous studies about the history of Korean criticism was a prejudice.

오분자기를 보다 效果的으로 利用하기 위한 基礎資料를 얻기 위하여 오분자기를 脫殼, 凍結한 후 凍結貯藏中의 品質의 變化를 實驗하였다. 凍結貯藏中 pH는 거의 變化가 없었고 drip量 조금씩 增加하였으며 揮發性鹽基窒素도 조금씩 增加하였으나 -35℃의 경우 3個月까지는 좋은 鮮度를 維持하였다. 保水力은 점차 減少하여 貯藏 3個月후에는 -10℃에서 貯藏한 경우가 10%, -35℃는 약 7%까지 減少하였다. hardness는 -10℃와 -35℃ 다 같이 1個月까지 增加하다가 以後 급격하게 減少하였으며 toughness는 계속 減少하였다. cohesiveness는 -10℃의 경우 큰 變化가 없었으나 -35℃의 경우는 2個月에 급격히 減少하였으며 elasticity는 -10℃와 -35℃의 경우 모두 큰 變化가 없었다. 色調의 變化에서 a값은 큰 變化가 없었으나 L값은 계속 減少하였고 b값과 ΔE값은 계속 增加하였다. 組織學的 觀察의 結果 貯藏溫度가 높은 것일수록 氷結晶의 成長과 근속끼리의 응집이 현저함이 確認되어졌다. To obtain the basic data for utilizing abalone, Haliotis diversicolor japonica more effectively the quality changes as pH, drip, water holding capacity (WHC), texture, color difference and histological observation in shelled and frozen products during storage were carried out. It was noticed that the pH of frozen products (-10℃ and -35℃) were not changed markedly, thaw exudate (drip) and volatile basic nitrogen (VBN) were slightly increased as the storing period prolonged but fairly good freshness was maintained until 3 months in the storage of -35℃. The water holding capacity for all frozen products were steadily decreased to show 10% and 7% down at -10℃ and -35℃ respectively with 3 months storage on the base of raw materials. With all frozen products it was observed that hardness was increased up until the 1 month storage period and then suddenly dropped while toughness was decreased steadily. NO significant changes in cohesiveness with the -10℃ storage were observed but with -35℃, it was dropped rapidly after 2 months storage while elasticity was not changed markedly for all frozen products. The color difference expressed as a value was not changed markedly while the L value was decreased steadily. The b and ΔE value were increased continually as the frozen period was extended. It was confirmed that both the growth of ice crystal and aggregates of muscle bundle were prominent at the higher storage temperature in histological observation.

배 경 : 저알부민혈증 및 C-반응 단백(C-reactive protein, CRP)이 증가된 지속성 외래 복막투석 환자의 사망률이 높은 정확한 이유는 밝혀져 않다. 혈액투석 환자에서처럼 복막투석 환자에서 저알부민혈증 및 염증반응이 심혈관계 질환 위험인자 인지 알아보고자 하였다. 방 법: 비당뇨병성 말기 신부전, 지속성 외래 복막투석 환자 93명의 심혈관계 질환 위험인자들과 복막 투과 특성 및 알부민, CRP 등의 염증지표에 따라 고해상도 초음파를 이용한 경동맥내막-중간막 두께, 내막-중간막 면적, 플라크의 유무 등을 단면적으로 비교하였다. 결 과: 복막 투과 특성은 고투과막군 14명, 중간 고투과막군 38명, 중간 저투과막군 31명, 저투과막군 10명으로 각 군간의 경동맥 내막-중간막 두께, 플라크 유무 및 내막-중간막 면적의 차이는 없었다. 기존 관상동맥 질환 환자는 8예(8.6%)로 내막-중간막 두께는 관상동맥 질환이 없는 환자보다 증가되었고(0.79±0.21 vs 0.60±0.11 mm, p<0.05) 플라크 형성은 더 많이 보이나 통계적 유의성은 없었다(75.0 vs 63.5%, p>0.05). 혈청 알부민치와 경동맥 내막-중간막 면적은 역상관관계를 보였다(r=-0.27, p<0.05). 저알부민혈증 환자(혈청 알부민 <3.5 g/dL)는 정상 알부민혈증 환자보다 내막-중간막 두께가 증가되었고(0.67±0.15 vs 0.61±0.12 mm, p<0.05), 플라크도 유의하게 많았다(68.0 vs 55.8%, p<0.05). 혈청 CRP치와 경동맥 내막-중간막 면적은 양의 상관관계가 있었으며(r=0.21, p<0.05) CRP가 높은 환자(≥0.8 mg/dL, n=18)에서플라크가 많이 관찰되었으나(65.8 vs 50.0%, p<0.05) 경동맥 내막-중간막 두께 및 내막-중간막면적은 양군간에 차이가 없었다. 다변량 회귀 분석상 경동맥 내막-중간막 두께에 영향을 미치는 인자는 고령, 높은 CRP, 기존 심혈관계질환, 낮은 혈청 알부민 순이였다. 결 론 : 복막투석 환자에서 고해상도 초음파를 이용한 경동맥 내막-중간막 두께 측정은 심혈관계 질환 유무 예측의 비침습적 검사가 될 수 있고 저알부민혈증 및 높은 CRP과 같은 만성염증 지속상태가 복막투석 환자에서 죽상 동맥 경화증의 발생을 증가시킨다고 가정할 수 있다. Background : Continuous ambulatory peritoneal dialysis(CAPD) patients with low albumin(LA) and signs of inflammation reflected by increased C-reactive protein(CRP) level have an increased mortality, but the mechanism of this phenomenon is not clear yet. Methods : To answer whether LA and inflammation also enhance cardiovascular risk in CAPD patients, we performed cross sectional study measuring carotid artery intima-media thickness(IMT), calculated intima-media area(cIM area) and the presence of plaque by high-resolution B-mode ultrasonography in 93 non-diabetic CAPD patients. Results : Patients with coronary artery disease (CAD, n=8) had significantly increased IMT(0.79± 0.21 mm vs. 0.60±0.11 mm, p<0.05) and higher prevalence of carotid plaques(75.0% vs. 63.5%) compared to the non-CAD patients. Significant inverse correlation was observed between serum albumin (SA) level and cIM area(r=-0.27, p<0.05). Those patients with LA(SA <3.5 g/dL) had significantly increased IMT compared to non-LA patients(0.67±0.15 mm vs 0.61±0.12 mm, p<0.05). Prevalence of carotid plaques was also significantly higher in LA patients (68.0% vs. 55.8%, p<0.05). CRP level revealed a significant positive correlation with cIM area(r=0.21, p< 0.05). Patients with high CRP(≥0.8 mg/dL, n=18) had higher prevalence of carotid plaques (65.8% vs. 50.0%, p<0.05) compared to those patients with CRP <0.8 mg/dL, but IMT and cIMT area were not different. By multivariate logistic regression analysis, old age, high CRP, history of CAD and low SA were the independent risk factors affecting IMT. Conclusion : Our study strongly suggests that low albumin and chronic inflammatory state of CAPD patients could be associated with increasing atherosclerotic cardiovascular disease.

To evaluate the in-vivo effects of mitomycin-C-polyglycolic acid composite(MMC-PGA) the disk: shaped composite were implanted into the peritoneal cavity of the Sprague-Dawley rats. The pathologic changes were examined at various time points up to 12 weeks. Initially the soft tissue around the inserted disks showed capillary congestion at 3 days. Inflammatory infiltrates with foreign body giant cells appeared from the 2nd week and reached peak response at 6-8 weeks. These reaction diminished prominently at 12 weeks. No specific pathologic change was found in the liver, the kidneys, and the heart. The above results suggest that the MMC-PGA composite can serve as a new device for intraperitoneal chemotherapy of various types of cancers.

To obtain the basic data for utilizing topshell, the changes of quality as pH, drip, free water content, water holding capacity, texture and color difference in shelled and frozen products during storage was studied. It was noticed that the pH of all frozen products (-10℃ and -35℃) were not changed markedly. Thaw exudate(drip) and free water content were increased as the storing period prolonged. The content of thaw exudate was risen slightly while free water content for all frozen products was increased notably marked 2.5 times in comparison with raw ones after 3 months storage. The water holding capacity for all frozen products were fell down steadily, it showed down 10% level at final stage of storage on the base of raw materials. It was revealed that the hardness and toughness were leveled up until the time of 2 months storage and then decreased moderately. There was not a significant change in elasticities and the degree of cohesiveness droped for all frozen storing periods. The color differences, expressed as L value mere reduced, the values of a and b were not changed markedly while the values of ΔE was increased as the frozen peried was extended.
