In order to establish the processing condition of salt-fermented liquefaction of sardine (Sardinops melanoslicta), effect of temperature, pH value, and concentration of salinity on crude enzyme activity of sardine viscera were investigated. The optimum temperature range of crude enzyme activity in sardine viscera was $45{\sim}50^{\circ}C$ and the optimum pH value of it was 9.8. According to the concentration of salinity increased the crude enzyme activity in sardine viscera decreased. The relationship between concentration of salinity (X) and the crude enzyme activity (Y) in sardine viscera is shown as follows; Y=-0.01363X+0.7676 (r=-0.88). For the purpose of processing conditions of rapid- and low salt-fermented liquefaction of sardine, changes of viable cell count, histamine content, and volatile basic nitrogen (VBN) in the chopped whole sardine with 8% NaCl during preheating process at $40^{\circ},\;45^{\circ}$ and $50^{\circ}C$ for 48 hrs were analyzed. During preheating, initial viable cell counts of chopped whole sardine were $10^{4-7}/g$, but they decreased $10^{1-5}/g$ after 48 hrs. Histamine contents during preheating process at $40^{\circ}\;and\;45^{\circ}C$ were gradually increased, whereas at $50^{\circ}C$ were almost the same level after 48 hrs. VBN contents were continuously increased during preheating, but preheating at $50^{\circ}C$ samples were lower level than that of $40^{\circ}\;and\;45^{\circ}C$ ones. For the purpose to accelerate the fermentation and liquefaction of chopped whole sardine, preheating at optimum temperature of crude enzyme activity for 48 hrs was useful processing method and the contents of viable cell count, histamine, and VBN were safety level for food sanitation.

This experiment was carried out to study the effects of light intensity and soil water regimes on the growth of ginseng seedling. The results were as follows: 1. The maximum light intensity and optimum temperature in 1,le photosynthesis of ginseng seedling were 10,000 lux and 23 $^{\circ}C$. Respiration rate was increased at high temperature. 2. Air and soil temperature under the shading were increased as the increase of light intensity but soil water contents were decreased as the increase of light intensity, whereas air and soil temperature were decreased as the increase of precipitation under the shade b5: soil water contents were increased as the increase of precipitation under the shade. 3. The higher the transmittance of the shade, the greater the specific leaf weight (S.L.W.) and stomatal density. In contrast, however, the contents of total chlorophyll, chlorophyll a and b, and stomatal length was decreased. There was no any significant difference light intensity of the a/b ratio of chlorophyll. 4. The highest photosynthesis was occurred in ginseng leaves grown under the shade 5% L.T.R. and net photosynthesis rates increased with increasing soil water contents. 5. Optimum condition for usable seedling yield were 5% L.T.R. and 3.3% precipitation under the shade. Useless seedling increased with increasing precipitation under the shade.

In order to decide the optimum planting time for Bupleurum falcatum L. which is grown widely in Korea, some experiments were carried out in different regions such as mid-north area (Gangwon-do, Gyeonggi-do and Chungcheongnamdo), mid-south area (Jeollanam-do, Jeollabuk-do, Gyeongsangnam-do and Gyeongsangbuk-do). The mid-south area had the highest total saikosaponin contents of 1.001, which is the medicinal ingredients of Bupleurum falcatum L., in accordance with the different Bupleurum falcatum L. regions. Also this area has the highest extract contents of 24.3%. Average dry root yields in mid-north area (Gangwon-do) were $450{\sim}460$ kg/ha at planting time of March 20th to March 30th, 500 kg/ha at the time of March 30th to April 10th, and $470{\sim}480$ kg/ha at the time of March 10th to March 20th in Chungcheongnam-do. The optimum planting time in the mid-south area (Jeollabuk-do) was March 10th to March 30th with the average dry root yield of $490{\sim}550$ kg/ha. Average dry root yield in Euiseong, Gyeongsangbuk-do area was 470 kg/ha, and the optimum planting time was April 10th, which suggested that the yield increased as the planting time was delayed. At Jeju-do, the volcanic soil of farsouthern area, average dry root yield was 510 kg/ha at the time of March 10th, but the yield from non-volcanic soil was lower than from volcanic soil, which had a dry root yield of 470 kg/ha.

최근 터치스크린을 탑재한 휴대폰의 출시가 늘어나면서 기존의 모바일 게임 콘텐츠를 터치스크린 콘텐츠로 변환하여 재사용하고자 하는 요구가 증가하고 있다. 하지만, 기존에 개발된 콘텐츠는 터치스크린 인터페이스를 갖고 있지 않기 때문에 터치스크린 콘텐츠로 자동 변환하는 것은 매우 어려운 문제이다. 본 논문에서는 터치스크린 인터페이스가 없는 모바일 게임 콘텐츠에 대하여 키보드 인터페이스 정보를 이용하여 자동으로 터치스크린 인터페이스를 생성하는 방법을 제안한다. 이 방법은 콘텐츠에서 사용되는 키 이벤트의 종류를 분석하여 최적의 스크린 키보드 레이아웃을 구성하고, 터치스크린 이벤트에 대해 자동으로 대응되는 키 이벤트를 발생시켜 키보드 이벤트 핸들러가 실행되는 터치 스크린 인터페이스를 생성한다. 끝으로, 실험을 통해 콘텐츠에 최적화된 터치스크린 인터페이스가 생성됨을 확인한다.

The results of the manufacturing of instant sweet potatoes from Korea native sweet potatoes and researching nutritional aspects from it. 1. The optimum cooking time for the manufacturing of instant sweet potatoes are 30 minutes, then it water contents are 5%. 2. Along to increasing cooking time, the contents of saccharides and another nutritive is increased, and it has almost constant value in the contents of saccharides. 3. Instant sweet potatoes are a good vitamin food because Vitamin C n the sweet potatoes is destroyed a little through cooking process, but instant sweet potatoes contain much of Vitamin C more than cereal, as 0.146%.

Optimum condition for cultivation of Anemarrhena asphodeloides B$_{UNGE}$ and seasonal variation of saponin and sapogenin contents in the rhizome were investigated. It is confirmed that the best harvest time is 3rd year. Average contents of saponin in rhizome was 8.5% and 5.0%, in fibrous roots, being highest in winter. The facotrs of saponin content variation were seemed to be temperature and humidity. It was also proved that asphonin was the mixture of timosaponin A-III, timosaponin A-I and mangiferin. Mangiferin and isomangiferin were isolated from the flower.
