  • To develop a ginseng wine, the brewing conditions and sensory evalution of the wine were studied. The ginseng, ginseng marc and red ginseng marc can be made into wine by ethanol fermentation with Saccharomyces cerevisae. The results showed that the higher ginseng concentration was, the faster the brewing velocity became. The ginseng marc wine brewed with 10% ginseng marc and 25% sugar was a great favorite The results from the mixture of ginseng and ginseng marc revealed that the mute the content of ginseng was, the faster the velocity of brewing became. It took 27 days for a wine from 10% ginseng marc to be brewed Into 12% ethanol, 10% ginseng took 10days and red ginseng took 15 days. Among these, a wine from 10% ginseng was superior to others in flavor, color and taste. And the wine from 6.7% red ginseng was favorite. Contents of the favorite wine from ginseng marc were 80mg/ml of reducing sugar, 2.6 of acidity, 12% of ethanol, 28mg/ml of saponin, and it's pH was 3.5. Contents of the favorite wine from red ginseng marc were 58mg/ml of reducing sugar, 2.8 of acidity, 12% of ethanol, 44mg/ml of saponin, and it's pH was 2.8.

  • Government has propelled strongly the Agricultural - cum - Industrial region development project in the nation wide. This project will not only provide employment opportunity for rural inhabitants, but also be designed to activate the rural economy. In addition, it will lead to a balanced development between the urban and rural areas. Under this project, building sites of 3 to 30 hactres will be established in the rural area in order to settle factories which are suitable to the rural condition. In this report, the researches which relating to the achievement conditions of planning, design and constructions of the building sites and the contribution conditions of Agri. - cum - Industrial Region development projects, activated to the rural economy and regional development in the Kyungpook regional areas, were surveyed and studied. On the average evaluation studies the results are as follows : 1. The achievement conditions of the planning, design and construction of the building sites. Very good 27.0 % Good 47.0 % Fair 24.0 % Poor 2.0 % 2. The contribution conditions of the Agri - cum - Industrial factories managements. Very good 17.0 % Good 41.0 % Fair 32.0 % Poor 10.0 %

  • The assesment of the safety of ship's transit in a curved narrow channl consists of the maneuvering safety determined by the chance of running aground, the maneuvering difficulty determined by shop's workload, and shiphandler's subjective evaluation. In this study to examine the correlation between shiphandler's subjectice evaluation and the maneuvering risk, the real-time and full-mission shiphandling simulator in the Korean Marine Training & Research Institutes(KMTRI) was utilized. In the conning bridge of the shiphandling simulator, 50 experienced masters conducted masters conducted the modeled vessel of 60,000 deadweight tonnage along the designed channel under 3 different envrinmental conditions. The findings were as follows: (1) The frequencies of stress levels, work difficulties, vessel controllability and overall workload of shiphandlers are similar irrespective of environmental conditions and they are able to be represented as shiphandler's subjective evaluation. (2) It is possible to assess and analyze theoretically the correlation between the shiphandler's subjective ecaluation and maneuvering risk each environmental cindition by quantifying the data obtioned from the tests. The results are as follows: ① As the degree of maneuvering risk increases, the shiphandler's subjective evaluation increases sharply near the curvature area of the desgined channel. ② In the area of the curvature of the designed channel, maneuvering risk increases sharply with the danger of running aground under the environmental condition of current and wind comung from the stem.

  • 본 논문에서는 분산 무선망에서 CSMA프로토콜을 사용한 무선통신 시스템을 모델링하고, 컴퓨터로 시뮬레이션을 수행하여 패킷의 도착율(arrival rate) 함수에 의한 평균 END-to-END 지연특성을 살펴보았고, 또 모델링 을 수학적으로도 해석하였다. 이 무선 통신시스템은 단방향 통신방식으로 비동기식 1-persistent CSMA프로토콜을 사용하였으며, 또 모든 무선 통신시스템들이 근거러 영역에 적절하게 위치하고 있다고 가정하였고, 트래픽이 공용채널에 포아송 분포를 이루고 있다고 가정하였다. 이 모델의 해석에서는 무선 통신시스템이 breakdown 특성을 갖는 M/D/1 모델을 기본으로 하였다. 결과적으로 본 논문의 모델에 기초한 무선망은 패킷도착율이 2(packet/sec) 미만인 경우 평균지연시간이 패킷전송시간의 2배정도로 잘 동작됨을 확인할 수 있다.

  • In order to develop a specific genetic marker for the Korean native cattle (Hanwoo), an arbitrarily-primed polymerase chain reaction (AP-PCR) analysis of 6 different cattle breeds was attempted. Eight different arbitrary primers, each longer than 20-mer nucleotides, were used. In comparison to the AP-PCR patterns, several distinctive DNA bands that are specific for a certain breed were detected. When the primer Kpn-X was employed, a 280bp DNA fragment was found to be specific only for Hanwoo. In an individual analysis of Hanwoo, this AP-PCR marker was observed in 123 head of cattle among the 153 that were tested (80.4%). Nucleotide sequencing revealed that this fragment has a short microsatellite sequence of tandem repeat, $A(G)_{1-2}\;(C)_{1-3}AGAG$. According to the analysis of AP-PCR band patterns, Hanwoo was discovered to be genetically most closely-related with Holstein among the various cattle breeds.

  • A micro-fuel processor system integrating steam reformer and partial oxidation reactor was manufactured using low temperature cofired ceramic (LTCC). A CuO/ZnO/$Al_2O_3$ catalyst and Pt-based catalyst prepared by wet impregnation were used for steam reforming and partial oxidation, respectively. The performance of the LTCC micro-fuel processor was measured at various operating conditions such as the effect of the feed flow rate, the ratio of $H_2O/CH_3OH$, and the operating temperature on the LTCC reformer and CO clean-up system. The catalyst layer was loaded with "Fill and Dry" coating for small volume. The product gas was composed of $70\sim75%$ hydrogen, $20\sim25%$ carbon dioxide, and $1\sim2%$ carbon monoxide at $250\sim300^{\circ}C$, respectively.

  • This study was experimented saccharification process added malt extract solution into cooked sweet potato and potato with time, temperature and was tested reducing sugar changes, structural changes, pH and sensory evaluation about cooked shik-hae of rice, glutinous rice, potato, sweet potato. The results are summarized as follows: 1. Enzyme activity was highest in malt after four days of barley germination at a room temperature. 2. Electronmicroscopic observation indicated that raw starch granule of potato and that of sweet potato was 25-60$\mu\textrm{m}$ and 8~18$\mu\textrm{m}$ in size, respectively and its shape is oval and globular for potato and sweet potato respectively. 3. Reducing sugars were 1,682.6mg and 1,695.6mg in rice and glutinous rice, respectively, for 6-hour-saccharification at $50^{\circ}C$. Reducing sugars were 1,689.1mg and 1,497.8mg in sweet potato, potato, respectively, for 6.hour-saccharification at $60^{\circ}C$. 4. pH variation during saccharification for sweet potato and potato was pH 5.8~5.4. 5. Sensory evalution showed that there were more significant differences in sweety odor, roasted nutty taste and sweety taste of sweet potato among four samples than the other's color shininess.

  • The main purpose of this study is to define the characteristics of emvironmental-friendly design which is found on in the planning of apartment housing complex. For this purpose, the subject of analysis were focused on the plans which had been authenticated an apartment housing complex development of Green Buildings. In conclusion, the characteristics of environmental-friendly design in the of apartment housing complex which are analysed through this study can be summarized as follows: It is shown that most plans hardly used the designs items such as 'preserving geographical feature' , 'use of substitutive sources' while the application ratio of 'making streamlets' , 'artificials afforestations' , 'making pedestrain road and bicycle road' is highest. this analysis means many planners and designers depends on only a few design elements when they plan apartment housing complex. it is because they don't have a correct understanding of environmental-friendly development.
