To utilize abundant poor persimmon fruits effectively, it was studied on alcohol fermentation strains which were isolated and indentified from poor persimmon fruits. The strains which had exellent alcohol production ability were analysized morphogical, cultural characteristics and identified Saccharomyces cerevisiae YJK 20, Sacahroimyces kluveri DJ 97. Alcohol production ability between the isolated strains and industrial alcohol yeasts was compared in the YPD medium, persimmon extract medium. Isolated strains had high alcohol production ability in both of two medium, respectively. So it was expected that the strains, YKJ 20 and DJ 97 had good alcohol fermentation ability of persimmon fruits.

The objective of this study aims to investigate preferred factors of golf knitwears for adult men and women playing golf. The 276 questionnaire was distributed to adult men and women who live in Busan and play golf. The data analysis method was implemented by frequency, t-test, and factor analysis with SPSS_ Win10 program. The results of this study are as follows: 1. The preferred factors were classified by 7 factors: 'luxury', 'function', 'distinct' 'activity', 'casual', 'neat', and 'individual'. 2. As for the 'individual' factor, there was a significant difference between gender. Male golfers considered more important than female golfers in individual and gorgeousness image. 3. There were significant differences between age groups in the 'luxury', the 'distinct', and the 'activity' factors. As for the 'luxury' factor, the group aged 30's considered more important than the group aged over 40's. As for the 'distinct' and the 'activity' factors, the group aged 40's and above were observed to consider more important than the 30's group. 4. As for the 'distinct' and the 'activity', the group aged over 40's were observed to consider more important than the group aged 30's. The older, the more preferred young design. As for the 'function' factor, it was observed that indoor golfers considered more important than outdoor golfers.

Drosera spatulata는 영양분의 요구도가 낮아 1/2MS배지에서 가장 많은 식물체가 재생되었다. 대부분의 Drosera속 식물들은 식물체의 재생과 생장에 질소원의 요구도가 낮아 D. spatulata와 D. rotundifolia의 경우 MS배지의 1/4배에서 가장 많은 식물체가 재생되었다. 적정 sucrose의 농도는 식물의 종마다 달라 D. spatulata의 경우 4%에서 D. rotundifolia는 1%에서 무처리구에 비해 많은 식물체의 재생을 보였다. 대부분 활성탄은 식물체의 재생에 효과적이었으나 뿌리의 형성은 억제되는 경향이었다. D. spatulata는 0.05%에서, D. rotundifolia는 0.01%에서 가장 많은 식물체 재생을 보였다. 식물체 재생은 D. spatulata는 0.6%의 agar를 첨가한 배지에서 D. rotundifolia는 액체배지에서 가장 효과적이었다. pH 실험의 결과 D. spatulata는 pH 4.5에서 가장 많은 식물체 재생을 보였다. The study was conducted to fine out the effect of Drosera species showed generally low nutrient requirement, the highest shoot production was obtained with 1/2 strength of MS medium for D. spatulata than with any other strength of MS medium tested. The nitrogen requirement of Drosera species were also relatively low. The maximum shoot regeneration was achieved when cultured in 1/4 strength of nitrogen contained MS medium. The optimum sucrose concentration for each species was different, such as 4% for D. spatulata; 1% for D. rotundifolia. In general, activated charcoal had positive effect on shoot proliferation, but had negative effect on root formation of Drosera species. The best shoot regeneration was achieved on MS medium containing 0.05% activated charcoal for D. spatulata, 0.01% for D. rotundifolia. Shoot regeneration of Drosera rotundifolia was better in MS liquid medium and D. spatulata showing best results on 0.6% agar. The maximal shoot proliferation was achieved on the media adjusted to pH 4.5 for D. spatulata respectively.

To utilize deteriorated sweet persimmon effectively, response surface methodology(RSM) was used to determine the optimal vinegar fermentation conditions and monitored by a divided two stage fermentation. The optimum conditions for maximum alcohol content were obtained when the first stage (alcohol fermentation) was carried out with an initial sugar concentration of 18.5°Brix, agitation rate of 140.8 rpm, fermentation time of 127.6 hr. When sugar concentration was 14°Brix, maximum alcohol content(7.1%) was predicted at fermentation conditions of 160 rpm in agitation rate, 140 hr in fermentation time. The optimum conditions for maximum acidity were obtained when second stage(vinegar fermentation) was carried out 249.5 rpm in agitation rate, 148.8 hr in fermentation time. Predicted values at the optimum conditions were similar to experimental values.

Grape vinegar(A) and grape onion vinegar(B) added (3% of onion juice) were produced through two stages of fermentation(alcohol fermentation and acetic acid fermentation) to increase the grape's use. Grape wine which contained 5.6% alcohol was produced on the 3rd day of first stage. Then through the second stages, grape vinegar, of which total acidity was 5.37% was produced. The quality of (A) and (B) which was produced through the two stages of fermentation was compared with the traditional grape vinegar(C,D) in the market. The content of sugar in (D) was a little higher such as 5.4 °Brix than others. That of (A) and (B) was 5.13, 4.98 °Brix respectively. The content of remaining alcohol in (C) was high such as 0.23% comparatively, But there was no remaining alcohol in (A) and (B). The content of acetic acid was 4.3~5.3% as a major organic acid of vinegars. The content of tartaric acid was 340.0 in (A), 316.7 in (B), 322.6 in (C) and 391.7㎎% in (D). The content of lactic acid was distinctly high such as 277.4㎎% in (D). There were differences such as 9.2~15.5㎎% in the content of total free amino acids among grape vinegars. (D) contained 15.5㎎% of total free amino acid and (B) also highly such as 12.0㎎%. Potassium was high in grape vinegars. The content of potassium, sodium and copper was higher in (A) than (B).

Recently, the advanced industries using micro parts are rapidly growing. Micro end milling is one of the prominent technology that has wide spectrum of application field ranging from macro to micro parts. Also, the method of micro-grooving using micro end milling is used widely owing to many merit, but has problems of precision and quality of products due to tool wear and tool fracture. This study deals with condition monitoring using acoustic emission(AE) signal in the micro-grooving. First, the feature extraction of AE signal directly related to machining process is executed. Then, the distinctive micro end mill state according to the each tool condition is classified by using the fuzzy C-means algorithm, which is one of the methods to recognize data patterns. These result is effective monitoring method of micro end mill state by the AE sensing techniques which can be expected to be applicable to micro machining processes in the future.

Physicochemical properties of marketing and intensive persimmon vinegar were investigated, the results are as following: Total. acidity in D, H, S, J, sweet persimmon(SP) and persimmon vinegar were 4.20, 3.03. 2.58, 3.30, 5.92 and 5.81%, respectively, and the value of intensive persimmon(IP) vinegars were higher than that of others. SP sample was lower than any other vinegar as compared to L value in colors, no sample was lower than H and S vinegar in turbidity and browning. Brix of IP samples were lower than that of other vinegars, there was a little fructose in the all samples. Among the organic acids, galacturonic acid content except acetic acid was the highest, and ascorbic and malic acid were detected a little. Calium content was the highest of minerals in persimmon vinegars, phosphorus was detected a little. Alcohols of 5~6 types were analyzed in each samples, free amino acids of 17~24 types were analyzed, D and IP vinegars have more alcohols and amino acids, and their contents were higher than the others. Volatile components of 6~9 types were analyzed in each samples, these have more ethanols except acetic acids than other volatile components, and the contents of IP samples were higher than that of marketing persimmon vinegars.
