본 연구는 밤가공 과정에서 폐기물로 나오는 밤껍질에서 분리한 밤 가루의 이화학적 특성을 규명하고, 식품 자원으로의 이용가능성을 검토해보고자 빵, 국수, 묵 등 식품을 제조하여 기호성과 관능검사를 실시하였다. 밤 가루의 물결합능력은 순수한 밤에서 분리한 것보다 껍질에서 분리한 것이 약 40%정도 높았으며 요드반응은 유사한 상태를 보였으며 amylose 분해한도는 밤 껍질에서 분리한 밤가루가 약 8.0%높았다. 밤 가루로 만든 빵, 국수, 묵 등은 냄새, 경도, 탄력성, 응집성, 부착성, 씹힘성, 검성 등에서 밀가루나 도토리로 만든 것과 유의적 차이가 없었다. Chestnut processing plants have wasted large amounts of chestnut inner skin waste, which contains chestnut flesh. To review the availability of the chestnut flesh as a food ingredient, We have analyzed the physiochemical characteristics of the chestnut powder extracted from inner skin waste. Then, we have examined on tastes and other sensory tests using breads, noodles and jellies made from various percents of chestnut powder. The results are as follows; The water absorbing capability and amylose degradability of the powder from the inner skin waste are 40% and 8% higher than those of the core chestnut powder, respectively. Also, the power from the inner skin waste shows similar characteristics with one of the core chestnut in iodine reaction. The breads, noodles and jellies from the chestnut powder have similar characteristics in flavor, hardness, elasticity, cohesiveness, adhesiveness, chewing property, and gumminess with the traditional ones.

스키선수들의 경쟁불안이 경기력에 미치는 영향

The present study aims to provide a foundation for developing the psychological skills drill program for the ski players in order to improve their psychological control which is essential to enhance their athletic performance. For this purpose, the authors investigated rivalry anxiety before and during the competition and analyzed the relationship between multi-level anxiety elements and the athletic performance. The results of the research are as follows: First, there was no significant difference in cognitive anxiety, physical anxiety, and confidence on the measuring time depending on the level of athletic performance, age and experience. Second, there was significant difference in the matter of degree and variance in relation to CSAI-2 on the measuring time. Third, on the measuring time depending on the level of athletic performance, the superior players remained similar level of CSAI-2 in relation to anxiety and confidence, but the common players showed significant individual difference. The results of the research suggested that the degree of anxiety and confidence are different among players. In other words, most of the players regardless of experience, age or athletic performance had anxiety before and during the competition, and the degree of anxiety exerted big influence on their performance. Therefore, it is a matter of great importance to solve the elements of this anxiety Though the results of the present study did not coincide with what the authors intended, we confirmed the individual difference of anxiety before and during the play. Many of the players seemed to be good players at their academic years and did not show much difference in rivalry anxiety. Individual analysis, however, showed a lot of difference in such a way that some had high degree of cognitive and physical anxiety at the beginning, while others had low degree at the beginning but had gradually increased the degree of anxiety. Consequently, the degree of anxiety that the players felt are different depending on the situation. In other words, the difference arises from how much importance the players grant on, who is the rival player, the intensity of practice before the competition and the record during the practice. Especially, it seemed that the gradual increase in physical anxiety over time was because it was the last game, and the players had lost some of their stamina.

인구의 도시집중화와 물질의 소비증가, 일회용품의 대량 사용으로 인한 쓰레기량의 증가는 환경파괴의 원인이 되고 있다. 환경보전과 자원보전의 차원에서 쓰레기 감량을 위해 배출량의 억제와 재활용 증진은 합리적인 쓰레기 처리 계획의 기본 출발점이기도 하다. 도시폐기물에 관련된 종합적이고 세부적인 정보들은 미래의 발생량과 질을 예측하는 등 장기적인 폐기물 관리계획을 수립하는데 중요한 참고자료가 되며 이러한 계획들은 쓰레기 발생량과 질을 예측하기 위한 분석에서부터 시작해야 한다. 광주광역시는 자원화를 위한 처리시설과 재활용률이 다소 부족하므로 체계적인 관리를 통한 개선은 더욱 절실한 실정이다. 본 연구는 7년 동안 우리나라와 광주광역시의 쓰레기 발생량 통계 및 발생경향을 분석함으로서 향후 광주광역시의 현실적이고 실행 가능한 쓰레기 관리계획을 수립하는데 기초 자료로 활용하고자 한다. The growth amount of waste from highly populated cities, increase consumption of material and large usage of disposables cause environmental demolition. Controlling waste discharge and encouragement of recycling are fundamental starting point of the rational waste management plans for environmental preservation and conservation of resources. A city`s synthetic and detailed municipal waste data will predict a future quality and quantity of waste generation and will become important references to establish plans for waste management. The plan should begin with analysis of the quality and quantity of waste for predicting a future quality and quantity of waste generation. Gwangju metropolitan city is lack of handling facilities and rate of recycling for making resourceful materials; therefore, it extremely need to be improved by systematic management. During the seven years of research, by analyzing Korea and Gwangju metropolitan city`s figures of amount of waste generation and trend of generation, we put this fundamental data to establish realistic and deliverable plans for waste management.

음식물쓰레기의 퇴비화에 관한 기초적 연구

전병관(Byung-Gwan Jeon),허당(Dang Hur) 유기성자원학회 1996 유기물자원화 Vol.4 No.2

A fundamental study on composting garbage was performed in a laboratory scale of a high-speed composting reactor. Major parameters were moisture content, temperature and C/N ratio. The results are as follows; pH of the compost was the highest at moisture 60% and anaerobic condition occurred at 70%. It was, also, found that C/N ratio, caused a nitrogen loss due to an occurrence of plentiful NH3 • Under controlling Temperature, pH was the highest at 60.C and an inverse effect for Composting occurred under excessive Temperature as pH at 70.C was lower than that of soil. The variation of pH and C/N ratio was the lowest when C/N ratio was 25. The results obtained from composting garbage revealed that the best condition of composting occurred under 50 to 60% of moisture content, 60.C of temperature, and 25 of C/N ratio. It is believed that composting may be finished with in 56 hours if an optimal condition is setting up. 본 연구는 실험실규모로 제작된 고속퇴비화기를 이용하여 음식물쓰레기를 퇴비화하고자 하였다. 연구의 주된 지표는 수분, 온도, C/N 바였다. 수분을 조건으로한 실험에서 pH 변화는 60%가 가장 높았으며, 70%는 혐기성반응이 일어남을 볼 수 있었고 C/N비 변화에서는 NH3의 다량발생으로 질소소설의 우려가 있는 것으로 드러났다. 온도를 조건으로 한 실험에서 600C의 pH가 가장 높았으며 700C 의 pH는 토양의 pH 보다 낮게 나타나지나친 고온은 퇴비화에 역효과를 나타냄을 볼 수 있었고. C/N비의 실험에서는 C/N비 25가 pH와 C/N 비의 변화가가장작았다. 결과적으로 음식물쓰레기의 퇴비화에서 수분은 50-60%, 온도는 600C, C/N비는 25가 적당함을 알 수 있었으며, 조건을 잘 조절해 준다면 56시간안에 퇴비화가 가능할 것으로 판단된다.
