In order to gain a rationalized plan, the test has selected 32 farm-houses which hold over 400 chickens in the Pusan city. Then the actual condition of chickens was investigated from 1 Oct. 1965 to 31 Oct. 1965. The summalized results of the research are as follows; 1. Average 131 gr. of feed for poultry per a chicken are a dosage of a day, the average feed costs 2.06 won, the average laying rates 53 per cent, and the average price of each egg is 8.7 won. 2. This management test demonstrated that the feed cost rate in the total expense was 83 per cent, the egg cost rate in the income was 86 per cent, while the profits per 100 chickens were 100 thousands won annually. 3. According to the method of a simple management test, an index of the commercial profit has got the results as follows; As the commercial profit index exceeds 100 per cent, the poultry raising management is calculated by a benifit management. The average commercial profit index showed 216 per cent in the results of this management test. commercial price of an egg×laying rate÷egg price rate in the total income profit = --------------------------------------------------------------------- index(%) feed cost per a chicken in a day÷feed cost rate in the total expense 8.7×0.53÷0.86 ×100× = ----------------- ≒ 216% 2.06÷0.83 4. All of the farm houses want the improvement of facilities, the spread of well-bred chickens, the enlightenment of feeding, much production of self supply feed (pustures), and the exhaustive preventive of epidemics for the rationalized poultry management. 5. For stabilizing the poultry management, all of the farm houses need for an adequate control of demand and supply of feeds, and a stability of feed and egg prices.

동백종실 및 유박의 식품으로서의 이용성 검토

김영환,정현숙,김용두,최옥자,강성구 順天大學校 師範大學 附屬 科學敎育硏究所 1997 科學과 敎育 Vol.5 No.-

동백종실의 이용성을 검토하기 위해서 NaCl(1.5%), ethanol(99.9%), blanching의 방법으로 쓴맛을 제거하여 관능검사를 한 결과는 다음과 같다. 1. 동백종실의 쓴 맛을 제거하는데는 NaCl용액보다는 알콜이 더 효과적이었으며, blanching, NaCl용액 및 알코올을 병행처리 하였을때 쓴맛이 잘 제거되었다. 그러나 동백종실은 알맹이로 되어 있어 쓴맛의 제거에 많은 시간이 소요되고, 완전하게 쓴맛이 제거되지 않으므로 종실자체를 식품으로 이용하는 것은 문제점이 있다고 생각된다. 2. 동백유박의 쓴맛제거는 증류수와 NaCl용액에서도 쓴맛이 거의 제거되었으며, 알콜의 경우는 30% 농도일 때 가장 효과가 좋은 것으로 나타났다. 동백유박은 동백종실에 비하여 쓴맛의 제거가 훨씬 더 용이하였으며, 식품재료로서의 이용가능성에 대한 기호도가 높은 것으로 나타나 이를 이용한 식품의 개발은 가능하다고 생각된다. This study was carried out to investigate the utilization of Camellia seed and defatted Camellia seed flour as food. We removed bitter taste of Camellia seed and defatted Camellia seed flour by using NaCl solution, ethanol, and blanching method. The following are the results of a sensory evaluation. 1. It was bitter taste rather than color or flavor which has made a great effect on the possibility of utilization for food materials. Alcohol was more effective than NaCl solution in removing bitter taste of Camellia seed, while bitter taste was easily removed when the processing with blanching, NaCl solution, and alcohol was employed. Since Camellia seed was consisted of grain, however, much time was needed to remove bitter taste. Because bitter taste wasn't perfectly removed, it has a problem in using Camellia seed for food materials. 2. Bitter taste of the defatted Camellia seed flour was almost removed in the distilled water, NaCl solution, and alcohol with a variety of concentrations. When various concentrations of alcohol were used, 30% concentration worked best, Bitter taste of defatted Camellia seed flour was removed more easily than that of Camellia seed. In conclusion, it is thought to be possible to develop into food, because of a high possibility of utilization as food materials

매실의 野生酵母를 발효 실험을 통하여 酵母의 同定, 酒精, Fusel oil 및 香氣 成分을 分析한 結果는 다음과 같다. 매실에서 발견된 野生酵母는 Saccharomyce cervisiaeSP. 5종 Pichti속 3종. Torulopsis 2종을 同定하였다. 酒精 生成力은 일발연 1호가 16%였으며 野生 酵母Ⅰ,Ⅱ.Ⅲ,Ⅳ는 각각 15.2%, 14.1%, 7.64% 및 13.5%였다. Fusel oil 生命力은 일발연 1호가 2.7%, 396호가 2.6%였으며 野生 酵母 Ⅰ,Ⅱ,Ⅲ,Ⅳ는 각각 0.5%, 0.3%, 0.3% 및 0.5%로 나타 香氣 成分은 일반연1호, 396호, 野生 酵母Ⅰ은 비슷하였으며 野生 酵母Ⅱ, Ⅲ, Ⅳ는 香氣 成分이 많은 것으로 나타났다. This study was conducted to evaluate the alcohols and flavors through fermentational using the wild yeast isolated in Mume(prunus mume s.e.t.z.)and the wild yeasts were identified, concurrently. The alcohols and flavors were analyzed by chromatography. 5 species(Sacch,cerevisiae sp.), 3 species(Pichia genus)and 2 spcecies(Torulopsis sp.)were identified. In the alcohol yielding ability test of yeasts, the yielding ability was 16% in Sacch cerevisiae, and 15.2%, 14.1%, 7.6%and 13.5% in the wild yeasts(#1,2,3,4), respectively, while in the fusel, the percentage of fusel oil was 2.7% in Sacch. cerevisiae, 2.6% in sacch. formosensis, and 0.5%, 0.3%, 0.3%and 0.8% in the wild yeasts(#1,2,3,4,)respectively. The amount of flavors made by yeasts such as Sacch cervisiae, Sacch. formosensis and wild yeast #1 was similar in each case but that of the wild yearst #2,3,4 was much more than above 3 species yeasts.

This report aims to get a rationalization of dairy fanning and maximization of dairy income. In order to gain the suvey, I have selected -'0 dairy farm-houses in Pusan city. Then I have been caught some points of farm improvement and presented some rational plan of dairy farming through farm business survey and analysis from 1 May to 30 Nov. 1967. The summalized results of the research are as follows; 1. Out of 225 heads were milking-cow 120 heads, dry-up-cow 18 heads, rasing cattle 87 heads. 2. Average milk yield per a year of 138 heads milking-cow(including dry-up-cow) was 3.690kg. 3. Average 9.4kg of concentrate and 9.Okg of rougiiage(air dry matter) for milking-cow per a head were the daily feeding ration, nutrient content was 9.09kg of TDN and 1.24. kg of DCP, these content were more 53% of TDN and 82% of DCP than feeding standard (NRC). 4. The feed cost was 44%, the cost of labor 27%, manure and materials cost 5%, charge for renting and land rent 5%, depreciation cost of dairy cattle and building 16%, cost of small farming tools and other cost 3% of the total production cost. 5. Average production cost of milk per 1kg of milk was 32.25 won. average profit per 1kg of milk was 10.95 won (milk price was 43.2 won per 1kg). But it may be less than 28 won per 1kg of milk. 6. Average working time per 1 head of a year was 470 hours. But it may be less than 350 hours for the management of 8~10 heads per 1 person. 7. Out of the dairy farm-households surveyed, 11 houses were in the blade farming and 6 houses were in the red farming. Average pure profit per 1 head of a year was gained 20 thousand won that the rate of income may low. 8. Acording to the method of a simply commercial profit was gained to the rate of milk price for the gross profit and the rate of feed and labor cost for the production cost. Average commercial profit index has show 1.29 in the result of this farm survey. Commercial Profit index = milk price/rate of milk price for gross profit/cost of feed & labor/rate of feed & labor cost for production cost x 100 =17,956 thousand won/0.86/11,781 thousand won/0.71 x 100=1.29 It may be over 1.5 of the cmmercial profit index for 35 thousand won of the income per 1 head of a year.
