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.

There are increasing needs for welfare in industrial environments in modern society. Industrial health is one of the most important components of industrial welfare, and it includes maintenance and improvement of physical, mental, and social health of the workers, elimination of factors threatening workers, prevention and early intervention of industrial diseases. In this regards the importance of industrial physical therapy is increasingly recognized and the need of physical therapy in industrial field is increasing. The authors surveyed and analyzed the curricula of the departments of physical therapy to promote development of curriculum or program for educating specialized industrial physical therapists. There are 40 institutes opening the department of physical therapy, 4-year courses in 17 and 3-year courses in 23. Only 2 institutes have subjects that are directly related to industrial health. This means that specific educational program for specialized industrial physicaltherapists is not established yet though there are many needs for industrial health and physical therapy in industrial fields. But many topics or knowledge of industrial health or physical therapy are scattered in several subjects. So we suggest the needs of systematic reorganization of specific curriculum that including ergonomics and prevention and treatment of industrial diseases for education of specialized industrial physical therapist.

치간부 골내낭의 치주재생치료는 수술 후 발생할 수 있는 비심미성 때문에 치과의사에게 힘든 과제이다. 본 연구에서는 이러한 문제점을 해결하기 위해 치간부 골내낭의 bovine bone mineral과 enamel matrix derivative (EMD)를 이용한 재생 수술에 골막을 포함한 결합조직 이식을 동반한 임상증례를 소개하고자 한다. 임상적 및 방사선학적인 검사는 술 전과 수술 6개월 이후 시행하였다. 모든 임상 지표들이 개선되었고, 방사선학적 검사에서 골내낭이 감소함을 확인할 수 있었다. 또한, 부가적인 결합조직이식을 통해 치간부 연조직의 증대 및 형태 개선으로 인한 심미성이 증진되는 효과도 확인할 수 있었다. Regenerative therapy in an interproximal intrabony defect is a challenge due to unaesthetic appearance after surgery. In this article, we introduce a case series of additional use of autogenous periosteal barrier membrane combined with bovine bone mineral and enamel matrix derivative (EMD) in interproximal periodontal intrabony defects to overcome an aforementioned shortcoming. During the periodontal regenerative surgery, autogenous periosteal membrane was additionally adopted besides xenograft material and EMD. Clinical and radiographic examinations were performed before surgery and 6 months after surgical treatment. All clinical parameters were improved and the intrabony defects were resolved on the radiography 6 months after surgery. Moreover, soft tissue esthetics such as the contour of interdental papilla was better than that of conventional regenerative therapy. Periodontal regenerative therapy using several graft materials and bioactive materials was effective in the treatment of periodontal intrabony defect. Moreover, using of autogenous periosteal barrier membrane combined with xenograft and EMD has additional effect for the treatment of an interproximal intrabony defect in terms of augmentation of interdental soft tissue volume.

김현주,김성조,최점일,이주연,Kim, Hyun-Joo,Kim, Seong-Jo,Choi, Jeom-Il,Lee, Ju-Youn 대한치주과학회 2009 Journal of Periodontal & Implant Science Vol.39 No.1

Purpose: The non-carious cervical lesion(NCCL) is a loss of tooth structure at the neck of affected teeth that is unrelated to tooth caries. The reported prevalence of NCCL varies from 5% to 85%. Prevalence and severity of lesions have been found to increase with age. They are becoming more significant as people live longer and become more aware of the importance of oral health. The purposes of this study were first, to examine the periodontal conditions associated with NCCL, and second, to investigate the clinical effects of class V restorations of NCCL on periodontal tissues. Materials and methods: The sample size was 982 teeth of 50 subjects(25 male, mean age $52{\pm}7$) who were seen at the Department of Periodontology, Pusan National University Hospital. At the baseline examination, clinical periodontal parameters were measured. After the initial examination, 24 patients who were absent from hypersensitivity were selected. The teeth with NCCL were randomly divided into the test and control groups. The teeth in the test group were restored with flowable resin; the control teeth were not restored. Six months later, the clinical examinations were repeated. The data were analyzed using the SPSS program. Results: The results were as follows: 1) NCCL occurred on 45.8% of examined teeth. The percentage of affected teeth was higher in maxillary and premolar teeth. 2) The shallow saucer type was the most common. 3) Teeth with NCCL had more gingival recession, lower attachment level, and higher incidences of bleeding on probing(BOP) and plaque than NCCL-free teeth. 4) Six months later, gingival recession, attachment level, the percentages of BOP and plaque in the test group were lower than in the control group(p<0.05). Conclusion: NCCLs were more found in maxillary teeth, especially in premolar teeth. The results suggest that the restoration of NCCL could affect some periodontal parameters favorably.

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.
