This study was carried out to examine information regarding nutritional intake according to intake of health improving agents. For this study, 593 adults were interviewed face-to-face. The average ages of the participants were 58.8 years old in males and 56.1 years old in females. The percentage of individuals taking agents was significantly higher (p<0.05) among the females (22.1%) than the males (14.1%). Men showed a preference for taking animal protein bases restorative food and health supplements, while women preferred health supplements and nutritional supplements as improving agents. However, there were no significant differences between the two groups. The total daily food intake was also not significantly different according to intake of improving agents in the male and female groups. The male subjects who took improving agents showed significantly lower intake of potato and starches, pulses, fungi and mushrooms, seaweeds, oils and fat, as well as seasoning than those of non-users. Female subjects who took these agents also had a significantly lower intake of pulses, nuts and seeds than nonusers. No difference in the daily energy intake was reported in male and female groups whether the individuals were taking improving agents in male and female groups or not. However, in male subjects who took improving agents, there was a significantly lower intake of protein, dietary fiber, carotene, vitamin $B_1$, folate, vitamin C, vitamin E, plant calcium, potassium and plant iron than the male non-users. This study suggests that practical education be emphasized for proper nutrition intake thorough nutritional management according to improving agents.

This study investigated possibilities for a new reducing shrinkage method of soybean oil(SO) and waste oil(WO) to compare with shrinkage reducing agent(RS) and expansion additive(EA). There was no big difference to flow, air contents, and compressive strength of plain to use SO and WO. For the reducing shrinkage performance, SO and WO was more effective than RS and EA, because their fatty acid reacted with calcium hydroxide of concrete to turn soap. For the pore distribution by porosimter, $0.01{\sim}0.1{\mu}m$ pores of SO and WO were 0 ml/g, and $10{\sim}100{\mu}m$ also remarkably lower than any others. In these results, it inferred that they filled up capillary pore and mitigated autogenous shrinkage by their saponification of their fatty acid and calcium hydroxide.

The application of nature-based solutions, such as low impact development (LID) techniques and green infrastructures, for stormwater management continue to increase in urban areas. Plants are usually utilized in LID facilities to improve their pollutant removal efficiency through phytoremediation. Plants can also reduce maintenance costs and frequency by means of reducing the accumulation of pollutants inside the facility. Plants have long been used in different LID facilities; however, proper plant-selection should be considered since different species tend to exhibit varying pollutant uptake capabilities. This study was conducted to investigate the pollutant uptake capabilities of plants by comparing the dry matter and nutrient contents of different plant species in roadsides, LID facilities, and landscape areas. The dry matter content of the seven herbaceous plants, shrubs, and arboreal trees ranged from 60% to 90%. In terms of nutrient content, the total nitrogen (TN) concentration in the tissues of herbaceous plants continued to increase until the summer season, but gradually decreased in the succeeding periods. TN concentrations in shrubs and trees were observed to be high from early spring up to the late summer seasons. All plant samples collected from the LID facility exhibited high TP content, indicating that the vegetative components of LID systems are efficient in removing phosphorus. Overall, the nutrient content of different plant species was found to be highly influenced by the urban environment which affected the stormwater runoff quality. The results of this study can be beneficial for establishing plant selection criteria for LID facilities.

뇌졸중, 심근경색 등의 심혈관질환은 암과 더불어 우리나라의 주요 사망원인이다. 2002년 통계청이 발표한 2001년 사망원인통계를 보면 인구 10만명 당 암이 123.5명으로 1위, 뇌졸중 등 뇌혈관 질환이 73.8명으로 2위, 심장질환(허혈성 심장질환과 기타 심장질환 포함)이 34.2명으로 3위였다. 이러한 심혈관질환의 예방을 위해서는 평소 뇌혈관질환을 일으킬 수 있는 위험인자들을 잘 관리할 필요가 있다. 사망률이 높은 심혈관질환의 주요 위험요인은 성별, 연령 등 선천적으로 타고나는 고정요인과 흡연, 비만 등 본인의 노력에 따라 생활습관을 바꿔 위험을 낮출 수 있는 변동요인으로 나눌 수 있다. 성별, 연령은 바꿀수 없지만 생활습관은 바꿀 수 있다. 심혈관 질환 예방에 있어서 가장 중요한 것은 기본적인 건강관리 수칙인 금연, 과음하지 않기, 균형있는 올바른 식생활, 규칙적인 운동, 표준체중 유지하기, 정기검진 등이다.특히 심혈관 질환은 채소류와 식물성 단백질, 식물성 지방 등을 위주로 한 식이요법이 도움을 줄 수 있고 튼튼한 혈관을 가지기 위해서 질 좋은 단백질과 비타민ㆍ무기질을 충분히 섭취해야 하며 콜레스테롤의 배설을 돕기 위해 섬유소가 충분한 식사를 한다. 갑자기 추워진 날씨로 생명을 다투는 뇌졸중이나 협심증, 심근경색 등 심혈관 관련 질병이 발생하기 쉬운 겨울철이다. 행사가 많은 연말에 과음을 삼가며 금연하고, 평소 담백한 한식 위주의 식사, 꾸준한 운동 등으로 건강관리에 힘써서 치명적인 심혈관 질환에 미리미리 대비하도록 한다.

이름의 유래는 다양하다. 아래로 향한 꽃잎 모양이 처녀 미니스커트를 닮아 붙였다고 하며, 아래의 가지런한 잎들이 치마모양을 하고 있어 그런 이름을 붙였다는 사람도 있다. 일본 이름을 잘못 번역한 것이라 보고도 있다. 처녀치마는 초본류 중 얼마 안 되는 상록성 식물로써 백합과에 속하며, 고산의 능선 북사면이나 보통 산의 웬만큼 습기가 있는 골짜기에서 흔히 자생한다. 자생지에서 보면 한 겨울 꽁꽁 언 얼음골 옆에서도 녹색을 유지하며 꿋꿋이 견뎌낸다. 연중 상록인 잎 모양도 예쁘지만 봄에 피는 꽃은 매우 아름답다.

In order to retain the freshness of fruits and vegetables and to reduce the rate of disease damage, grafruit seed extract (GPSE), natural microorganism control agent, was applied during the preservation process of fresh fruits and vegetables. GFSE showed an effective inhibitory action against plant putrefactive bacteria and fungi which were involved in the decay of fruits and vegetables. Minimal inhibitory concentrations for GFSE against the microbes were in the range of 50 to 2,000 ppm. Direct observation of microbial cells and spores using electron microscopy showed their function was destroyed by the treatment of the dilute solutions of GFSE. Fresh Welsh onions, onions and red peppers treated with GFSE and stored in polyethylene film (0.1 mm) retained better quality in color and texture than the non-treated control. GFSE was efficient in controlling the germination of potatoes. It was observed that GFSE would reduce disease damages and have bactericidal and fungicidal properties during the storage of such fruits and vegetables as zucchinis, cucumbers, tomatoes and mandarin oranges.

Food consumption pattern between Korea and Japan were compared on the basis of the data from the National Nutrition survey which has been carried out annually in Korea (1969-1988) and in Japan (1950-1988) for the guide of the future food and nutrition policy. Total food intake has been decreased in Japan since 1973. In spite of fluctation of total food intake, there was an increase of food consumption in Korea. The intake of animal food has been increased, while that of vegetable food decreased, in both countries. Proportion of the total food intake from animal sources of Japanese in 1988, 25.3%, was greater than that of Koreans, 20%. The intakes of cereal and grain products have been decreased in both countries, but the amount of these food groups consumed by Koreans was 70 to 80g more than that by Japanese in 1988. When the animal food intake was compared, intakes of meats, fishes, shellfish and eggs have been increased considerably in Korea. Intakes of milk and milk products and meat have been increased, while those of fishes, shellfishes and eggs kept an even level since 1975, in Japan. According to changes of the national standards of height and weight in both countries, the average height has been increased greatly from 1970 to 1980 in Korea, and the tendency was the same for the average weight.

This study was carried out to investigate the plant growth of various ferns affected by the shading and fertilizer application and to recommend the appropriate levels of light intensity. Evergreen ferns like Dryopteris nipponensis Koidz., Cyrtomium falcatum (L. f.) Presl, Onychium japonicum (Thunb.) Kunze and deciduous ferns like Athyrium niponicum (Mett.) Hence, Thelypteris decursive-pinnata Ching, Athyrium brevifrons Kodama ex Nakai were used in this experiment. Evergreen ferns showed the best growth in the shading level of 30~60%. The plant growth and ornamental value (leaf color) of these plants were improved according to the fertilizer application in appropriate shading levels. The survival rate remained constantly in all treatments. Deciduous ferns showed the best growth in different shading levels from 0 to 60%. Some treatments showed improved growth according to fertilizer application, whereas survival rate was in the other treatments. There were differences in plant growth of evergreen and deciduous ferns according to fertilizer application, and additional researches must be executed to explain these reponses.

The accurate and simple extraction method for sterols and fatty acids in sesame oil was developed. The new method improved the extraction efficiency of sesamin in sesame oil and the ratio of sesamin over campesterol. It will be applied to judgement of adulteration of plant edible oils. The minor components of sterols were also confirmed. The simultaneous determination of sterols and fatty acids with derivatization were processed, but it was not enough to confirm adulteration, thus need more experiments.
