Effects of light and grazing on the biomass development of periphyton were evaluated using natural and artificial substrata (unglazed tile: 3.7×9.5x2cm) in a partially shaded 2nd order mountain stream. In open canopy (relative light input 20∼50%), a relatively high biomass (chl. a: 9.5±3.0 mg/m^2, n=25) was maintained than that of closed canopy(<6% of light input. 3.2±0.9 mg/m^2, n= 17). Due to shading and frequent rainfalls, biomass was lower during the summer than in the spring and winter. During the spring, colonization of periphyton on artificial substrata occurred faster than in winter and it took a minimum of 5∼6 weeks to reach the biomass of natural substrata (8∼9mg/m^2). When snails were allowed to freely enter the chamber (mean density: 114 ind./m^2) with artificial substrata, biomass accumulation (chl. a, AFDW) was low compared to the snail excluded enclosure (50∼90% of ungrazed substrata). It was concluded that the light input on periphyton biomass In a partially shaded stream played a more important role than glazing.

The objective of this study was investigated to apply the fucoidan and laminarin extract from low-grade Undaria pinnatifida to real food product, a pork patty. Pork patties added with fucoidan and laminarin showed lower lipid oxidation and the inhibition against lipid oxidation was shown to be dependent on the irradiation doses. The Hunter color values of pork patty added with fucoidan increased significantly with an increase of irradiation dose. The hardness profiles of the patties with fucoidan and laminarin was decreased, but the amount of water in the patties was increased. Also, the combination of gamma irradiation and addition of fucoidan and laminarin was shown to be effective for the microbiological control. These results suggested that gamma irradiation and fucoidan and laminarin treatment showed the positive effect on microbial stability and quality of the pork patty.

To develop a yogurt for sensitive consumer such as infants, children or immuno-compromised patients using gamma irradiation, the effects of gamma irradiation on the microbiological, chemical, and sensory quality in a commercial plain yogurt were investigated. No viable coliform bacteria were detected in the sample and approximately a 6 decimal reduction was achieved in the number of total aerobic bacteria by irradiation at 5 kGy. The initial population of lactic acid bacteria observed in the commercial plain yogurt was 8.95 log CFU/g. Gamma irradiation significantly reduced the initial microbial level to 6.47 and 2.85 log CFU/g after irradiation at 1 and 3 kGy, respectively (p<0.05). However, irradiation dose up to 5 kGy could not completely eliminate the lactic acid bacteria in commercial plain yogurt. pH, color, lactose and lactic acid content, and sensory quality were not affected by irradiation treatment and storage. Our results suggest that irradiation can improve the microbial quality of commercial plain yogurt without impairing the physicochemical and sensory quality.

Objectives : We conducted an epidemiologic survey to evaluate the effect of the aircraft noise exposure on the health of the residents near the military airbases in Pyeongtaek City. Methods : The evaluation of environmental noise level, questionnaire survey, and health examination were performed for 917 residents. The study population consisted of four groups: subjects who lived in the village close to the fighter airbase (high exposure), subjects who lived along the course of fighters (intermediate exposure), and subjects near a helicopter airbase, and the control group. Results : The prevalence of the aircraft noise related accident and irritable bowel syndrome in the exposure groups were higher than that of the control group. The risks of noise induced hearing loss, hypertension and diabetes mellitus were higher in the exposed groups than in the control group. The prevalence of anxiety disorder and primary insomnia were higher in the exposed groups than in the control group. Prevalence odd ratios of the risk for primary insomnia after adjusting age, sex, agricultural noise, and occupation were 4.03 [95% confidence interval (95% Cl) 1.56-10.47] for the subject near the helicopter airbase, 1.23 (95% Cl 0.40-3.76) for those intermediately exposed to fighter noise, and 4.99 (95% Cl 2.14-11.64) for those highly exposed to fighter noise. Conclusions : The results of the present study suggest that the aircraft noise may have adverse effects on hearing function, cardiovascular health and mental health. Therefore, it seems to be needed to take proper measures including the control of the aircraft noise and the management of the exposed people's health.

This study evaluated the physicochemical and sensory characteristics of vanilla ice cream treated with gamma irradiation. The general composition of the vanilla ice cream used for the study was 45.4-53.3% moisture, 5.5-5.9% fat and 3.9-4.1% protein, and these values did not change following gamma irradiation. The Hunter L, a and b values were slightly decreased following gamma irradiation. The fatty acid composition of the ice cream included caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid and stearic acid, and there was no detectable change following irradiation. There was no significant difference in TBARS (2-thiobarbituric acid reactive substances) values between non-irradiated and irradiated samples at a dose of 3 kGy or less (p<0.05). Sensory evaluation indicated that gamma-irradiated vanilla ice cream did not show any difference in color relative to non-irradiated ice cream. However, gamma irradiation did affect the flavor, taste and overall acceptability of ice cream at doses above 3 kGy. These results indicate that gamma irradiation at 3 kGy is an effective treatment for sustaining the physicochemical characteristics of vanilla ice cream with minimal changes in sensory characteristics, though further studies should be carried out to reduce the deterioration of sensory qualities induced by gamma irradiation.

254㎚ 이상의 파장을 갖는 자외선 램프가 설치된 광조사장치를 이용하여 상용성 저밀도 폴리에틸렌을 100시간 동안 광분해시켰다. 20여 단계가 넘는 복잡한 광분해 반응단계 중에서 필름의 물성을 크게 저하시키는 중요 3단계로 정하고 간단하게 변수를 정의하여 반응 모델식을 설정하였으며, IR 스펙트럼을 이용하여 광분해 과정중에 생성되는 과산화물과 카르보닐기의 흡광도를 시간의 함수로 해석하여 각 단계에서의 속도상수와 활성화 에너지를 구하였다. 이들 자료로부터 논란이 되고 있는 반응 메카니즘을 정리할 수 있었으며 속도 결정 단계를 정하였다. The LDPE films were photolyzed for 100 hours in UV apparatus with 400-W medium pressure mercury lamp radiating wavelengths longer than 254㎚. A simple kinetic model was introduced and was applied to interpret the FT-IR absorbance of carbonyl and hydroperoxide bonds as a function of UV exposure time. From these data, the reaction mechanism and the rate determining step of photodegradation were determined.

본 연구에서는 측면연마 된 광섬유 브래그 격자를 측면 연마하고 폴리머 상부층(overlay)를 형성시켜 외부 굴절률과 온도를 동시 측정할 수 있는 광섬유 센서 소자를 제안하였다. 외부굴절률 변화에 민감하지 않는 광섬유 브래그 격자를 이용하여 온도를 측정하고 격자를 측면 연마한 후 폴리머 코팅에 의해 소산장 결합을 유도하여 외부 굴절률 변화를 측정하게 된다. 측면 연마된 광섬유 브래그 격자의 온도 민감도는 0.01 nm/oC로 측정되었고 폴리머 상부층의 온도 민감도는 -0.58 nm/oC로 측정되었고 선형구간 별(1.33-1.39, 1.39-1.42, 1.42-1.44) 굴절률 민감도는 498.8 nm/RIU, 694.9 nm/RIU, 1312 nm/RIU로 측정되었다. A hybrid grating sensing device based on a side-polished fiber Bragg grating (FBG) with a polymer overlay is proposed for simultaneous measurement of external refractive index and temperature. The side-polished FBG, which is insensitive to ambient index change, is utilized for detecting temperature variation, and the polymer overlay is coated on the side-polished FBG for measurement of ambient index change. The temperature sensitivities of the side-polished FBG and the polymer overlay were measured to be 0.01 nm/$^{\circ}C$ and -0.58 nm/$^{\circ}C$, respectively, in a temperature range from $30^{\circ}C$ to $100^{\circ}C$. The ambient index sensitivities of the polymer overlay were measured to be 498.8 nm/RIU in an ambient index range from 1.33 to 1.39, 694.9 nm/RIU from 1.39 to 1.42, and 1312 nm/RIU from 1.42 to 1.44.
