일반인 중 심정지를 목격할 가능성이 가장 높은 중년층 여성들을 대상으로 숫자를 세는 방법에 따른 가슴압 박소생술의 질과 피로도를 비교하여 최초반응자로서의 역할을 위한 심폐소생술 교육 프로그램을 마련하는데 기초자 료를 제공하고자 한다. 3시간의 기본인명구조술 교육을 실시한 후, 확률할당을 통해 45명씩 두 그룹으로 배정하였다. 가슴압박소생술 도중 큰소리로 숫자를 세는 그룹 A, 숫자를 세지 않는 그룹 B로 나누어 인체모형에 2분간의 연구를 진행 하였다. 두 그룹간 가슴압박의 질은 유의한 차이를 보이지 않으면서 가슴압박의 중단시간이 단축되었고, 시간의 경과에 따라 흉부압박의 깊이가 줄어드는 빈도 또한 의미 있게 낮았다. 또한 가슴압박소생술 후 본인이 느끼는 피로 도 또한 의미 있게 낮았다. According to the comparing the quality and fatigue of Hands-only CPR with counting by middle-aged women who is most likely to witness the cardiac arrest. This paper wants to provide the basic data to establish a CPR education program for the role of the first responders. After conducted three hours of basic life support training, it divided into two 45-persons groups by assignment of probability. 2-minutes research conducted with dummy by dividing into Group-A that counting the number loudly during the Hands-Only CPR, And Group-B that does not counting the number during the Hands-Only CPR. Between the two groups, the quality of Hands-Only CPR does not showed its difference clearly and the downtime of Hands-Only CPR was reduced, Depending on the over time, the frequency that reduces the depth of Hands-Only CPR was also significantly lower. And after the Hands-Only CPR, the fatigability who felt themselves was also significantly lower.

해조류 중 생산량이 많고 건강식품 소재로서의 가능성이 높은 미역과 다시마 해조묵을 제조하여 수침저장 중 저장 온도와 시간에 따른 생균수, pH, 적정산도, 겔강도 및 TVN의 변화를 측정하여 적정저장 조건을 검토한 결과 묵 저장 중 겔강도는 약화되었으며, TVN, 생균수는 증가하였다. 조체묵의 수침저장은 $32^{\circ}C$에서는 3일, $18^{\circ}C$ 이하에서는 15일 저장까지도 가능하였으며, 두유혼합묵은 조체묵 보다는 저장 기간이 짧아서 $18^{\circ}C$ 저장시 3일까지 가능한 것으로 판단되었다. Seaweed Jellys(Muks) were prepared with sea mustard and sea tangle. Optimum storage condition was also investigated in terms of bacterial counts, pH, titratable acidity, gel strength and total volatile nitrogen(TVN) as soaking temperature and time in distilled water. Gel strength of Muk decreased, and TVN and baterial counts increased during storage in water. Seaweed Muk has a shelf life of 3 days at $32^{\circ}C$ in water and 15 days at $18^{\circ}C$. Shelf life of seaweed Muk with soy milk was 3 days at 18's and shorter than that of seaweed Muk without soy milk.

미역과 다시마를 원료로 한 해조묵제조를 위한 최적제조조건을 찾기 위하여 해조마쇄액의 용해 및 CaCl₂에 의한 겔화조건 등에 대하여 용해액의 점도 및 겔화한 묵의 젤리강도(jelly strength) 등을 기준으로 연구된 결과는 다음과 같다. 조체용해의 최적조건은 마쇄조체액에 1% K₂HPO₄용액을 1 : 1 (v/v)로 혼합하여 65℃, 1시간 가열이 적당하였다. 겔화시간은 60mesh로 여과한 조체용해액을 3배량(v/v)의 1% CaCl₂용액에 담가 Ca^(++)이 24시간 동안 자연침투되도록 겔화하는 것이 적당하였다. 용해 조체액의 점도와 겔화된 묵의 젤리 강도와의 사이에는 비례관계가 성립되지 않았다. 이때 미역묵의 젤리강도는 500g/㎠ 이상이였으며, 수율은 조체용해여과액의 87.5%였다. 다시마묵은 미역묵에 비해 젤리강도 및 비중은 높았으나 수율은 낮았다. To investigate the optimum conditions of seaweed Mooks prepared with sea mustard(Undaria pinnatifida) and sea tangel(Laminaria japonica), pH, viscosity, yield and jelly strength were studied on the sol and/or gel (Mook) made from homogenized seaweeds. Solubilization conditions of homogenized seaweeds were heating at 65℃ for one hour after mixing homogenized seaweed with 1% K₂HPO₄ by 1:1(v/v). Gelation conditions were 24hrs by natural permeation of Ca^(++) into the sol in three times(v/v) of 1% CaCl₂ solution to solubilized seaweed passed through 60mesh of sieve. There are generally no relationship between viscosity of solubilized seaweed and jelly strength of Mook produced by gelation of the sol in CaCl₂ solution. Jelly strength of sea mustard Mook was more than 500g/㎠, and yield was 87.5% of the solubilized and filtrated seaweed. Jelly strength and specific gravity of sea tangle Mook were higher those of sea mustard Mook, while its yield was lower than that of sea mustard Mook.

해조류 중 생산량이 많고 건강식품 소재로 가능성이 높은 미역과 다시마를 이용하여 두유와 분리대두 단백질이 첨가된 혼합묵의 제조조건을 규명하였다 두유혼합 미역묵의 제조는 두유의 비율을 증가시킴에 따라 겔강도는 감소되었고, 농축한 두유를 혼합할수록 겔강도는 증가하였다. 또한 조체용해액에 대한 두유의 비율을 7 : 1로 혼합하여 $65^{\circ}C$에서 겔화하는 것이 적절하였다. 조체용해액에 분리대두단백질을 $5\%$(w/w)를 혼합하여 $65^{\circ}C$에서 겔화할때 조체묵이나 두유혼합묵에 비해 높은 겔강도$(900g/cm^2)$을 가지는 분리대두단백질 혼합묵제조가 가능하였다 Seaweed Jellys(Muks) were prepared with sea mustard and sea tangle, Optimum conditions for preparation of seaweed Muks with soy protein were investigated. Gel strength of Muks with sea mustard and soymilk decreased as the quantity of soy milk increased, and increased as the moisture content of soy milk had been decreased. Optimum mixing ratio of seaweed and soy milk was 7 : 1 and optimum temperature of gelation was $65^{\circ}C$. Gel strength of seaweed Muk mixed $5\%$(w/w) of soy protein isolate was higher$(900g/cm^2)$ than those of seaweed Muks with and without soy milk.

A type zeolitic crystal film was synthesized on porous supports from the reaction mixture of 1.9 SiO₂-1.5 Na₂O-Al₂O₃-40 H₂O. The zeolite film was characterized by XRD and SEM. The crystals grown on the porous matrix were very closely bound together and the thickness of membrane was about 8 - l5㎛. The densely intergrown crystals could be also synthesized by e hydrothermal treatment at 100℃ after pressing the reaction mixture without addition of water, A zeolite membrane crystallized as a thin film showed the selective permeability of water from water and methanol mixture through the molecular sieving activity of micropores.

Feasibility of simultaneous removal of organic and nitrogen is evaluated as applying microbial entrapping method to treat fish processing wastewater. Treatability test is conducted immobilizing activated sludge from municipal sewage treatment plant to gel matrix made of cellulose triacetate. Stable operation can be possible when applying organic and nitrogen loading rate increasingly to wastewater treatment system composed of anoxic and oxic tank. Organic loading rate and nitrogen loading rate are applied 0.65-1.72kg COD/㎥/d and 0.119-0.317kg T-N/㎥/d, respectively. In case of wastewater from fish processing plant used in this study, it is evaluated that 0.3kg T- N/㎥/d is upper limit of applicable space loading rate because effluent T-N concentration is exceed 60mg/L, legal effluent dishargeable limit of T-N concentration in Korea, when space loading rate is exceed 0.3kg T-N/㎥/d. It is evaluated that nitrification of system is performed efficiently regardless fo variation of applied loading rate because removal efficiency of NH_(4)^(+)-N is relatively constant when the applied NH_(4)^(+)-N loading rate is increased gradually, while decrease of T-N removal efficiency is apparent when the applied loading rate is increased gradually. Nitrate removal efficiency in this study is varied from 98.62% to 99.51% depending on applied loading rate, while nitrification efficiency of oxic reactor is varied from 94.0% to 96.9%. It is showed that COD removal efficiency is varied from 94.2% to 96.6% and T-N removal efficiency is varied from 73.4% to 83.4% depending on loading rate applied in this study.
