This study was conducted to find out the successive habitual practice of dietary life and all the educational tasks for the purpose of activating with female college students in Korea and Japan. The reesults are as follows. Housewives in both countries prepare 「the same menu」 for dinner about 65%. 「The rate of domestic manufacturing of preservated food 」 is superior in Korea. 「Goch'ujang」 is made by the 92% of Koreans, 「Doenjang」 89%, 「Ganjang」 48%, 「Oiji」 44% and 「Kimchi」 40%. 「Umeboshi」 is made by the 65% of Japanese, 「Rakkyo-Zuke」 37%, 「Kajitsu-syu」 40%, and 「Miso」 27%. Two countries' common seasonings are 「Ganjang」, 「Salt」, 「Chemical condiment」, 「Sugar」, 「Pepper」, 「Doenjang」 and 「Vinegar」. Koreans use the traditional seasonings, and in addition flavoring vegetables and oil which is Korea's own characteristic. Japanese use western seasonings frequently besides traditional seasonings. 「Mother's representative food」 as home dish are conscentrated on each count's native food. 「Kimch'i lyu」 is made by the 42% of Koreans, 「Doenjangchigae」 39%, 「Dakgangjong」 31%, and 「Saongsonmaeuntang」 19%. 「Misoshiru」 is made by the 83% of Japanese, 「Nishime」 76% and 「Nikujaga」 38%. Korea has more diverse kinds of food. People eat out 「when they have special home events」, 「when they would like to do」, and 「when they are going out」, It means that to eat out is one of the daily dinning styles. Therefore, for those who are engaged in eating house business it is necessary to form their righteous view of evaluation. Koreans learn more various items of table manner than Japan, which are the symbols of dietary culture. 「Carriage」 and 「Eating politely」 are common items. The extent to which 「people practice table manner」 and to which 「people think of it as being worth practicing」 are high in Japan than Korea.

본 논문에서는 직장암 환자를 대상으로 일반적 치료방식인 3차원입체조형치료법과 선형가속기 기반의 I MRT, 그리고 토모테라피를 이용한 IMRT의 치료계획을 각각 수립하여 직장암 환자에 대한 최적의 치료법 을 비교하고자 하였다. 치료법 비교 결과 종양조직에서는 처방선량의 95% 이상의 흡수선량을 만족시키고 있었으며 정상조직인 방광, 소장, 넙다리머리뼈의 정상조직의 합병증 발생율의 기준(V40, V30, V20, V10) 을 만족하였다. 다만, 3가지의 치료법에서 선량분포측면에서 가장 효율적인 치료법은 Tomotherapy기반의 I MRT였으며 가장 낮은 효율을 보인 치료법은 3DCRT였다. 직장암의 방사선 치료시 환자의 자세재현성, 개 인적인 신체환경 등을 고려하여 가장 적합한 치료방식을 적용한다면 환자의 예후와 삶의 질에 긍정적인 효과가 나타날 것으로 사료된다.

This study was conducted to evaluate the contents of total polyphenol and flavonoid, and the effect of antioxidant, antimicrobial activities and cytotoxicity in vitro by different solvent fractions from Orostachys japonicus. The ethylacetate fraction extract for O. japonicus contained 634.48 ㎍/g polyphenol and 205.20 ㎍/g flavonoid. The ABTS radical scavenging ability of ethylacetate fraction extract at 1 ㎎/㎖ was higher than 95% which is comparable to ascorbic acid of 97%. The APX enzymatic activity and CAT activity were 1125.89 μmol ascorbate oxidized/min/㎎ protein and 119.87 H2O2 decomposed/ min/㎎ protein, respectively. In disc agar plate diffusion assay, the extract gave rise to a larger inhibition circle with Listeria monocytogenes, Staphylococcus epidermidis, Staphylococcus aureus and Malassezia furfur strains compared with antibiotics kanamycin suggestive of high antibiotic activity. The cytotoxicity of extracts of O. japonicus was significant differences between solvent fractions. That is, the cytotoxic effect against human cancer cell was higher in ethylacetate fraction extract than other fraction extracts. These results suggest that fraction extract of O. japonicus might be very effective and economical in developing natural antioxidant and antimicrobial.

Background : The effective components of Omija(Schisandra chinensis Bailllon) are lignans (schizandrins and gomisins), and this components were contented mostly in seed part on Omija, which have various physiological functionalities such as anti-cancer, anti-inflammatory, and antioxidant activities. Methods and Results : This study was carried out to determine effective condition(CO2, CO2+ethanol) on extraction using supercritical carbon dioxide extraction (SFE) system and to find interrelation on effective components and antioxidant activity of extracts and residues obtained after extraction. Effective components were analysed lignans and phenolic compounds and antioxidant activirty was determined for DPPH radical scavenging ability on methanol extracts of SFE-extract and SFE-residue. On SFE with ethanol, SFE extract was separated two phase, upper(water phase) and lower(oil phase). SFE-extract showed the highest total lignans content(61.36 mg/g, 72.14 mg/g on lower, 50.58 mg/g on upper) and the lowest total phenolic compounds(6.52 mg/100g) and SFE-residue showed the lowest total lignans content(1.45 mg/g) and the highest total phenolic compounds(16.23 mg/100g) by extracted on CO2+ethanol treatment. SFE-residue methanol extract showed the highest DPPH radical scavenging abilities and SFE-extract upper showed the lowest. Conclusion : Thus, this results showed SFE-extract showed the highest total lignans content, but SFE-residue showed the highest DPPH radical scavenging ability although the lowest total lignans content.

In this study, the leaching characteristics of magnesium from mine residue by acid leaching method was studied. First, It was confirmed the effect of the particle size. The particle size was selected 80 mesh in consideration of the leaching amount and recycling rate of Mg. And after, It was compared to the leaching characteristics of magnesium by H2SO4, HCl and HNO3. Among them, leaching efficiency of H2SO4 was best. After the experiments were conducted with H2SO4. The effect of various parameters such as acid concentration, reaction temperature, and liquid/solid ratio on the leaching process were investigated. It was determined that the leaching amount of magnesium increased with reaction acid concentration, temperature, and liquid/solid ratio, and decreasing particle size. Maximum leaching amount of magnesium was obtained at the condition of particle size blow 80 mesh, temperature 80oC, 6 M H2SO4, 10/1 liquid/solid ratio, 6 h of reaction time and 180 rpm.

Municipal Solid Wastes (MSW) are disposed of three types (recycling, incineration, landfill). The ashes made after the incineration are also recycled to minimize the volume of waste owing to reducing the amount of landfill. However, MSW incinerations (MSWI) in Seoul are not satisfied with the policy of Korea as a result of experiments about the chemical characteristics of the ash (Ignition loss, pH, Chloride, Cyanide, metals leaching). So, according to the policy, the MSWI in Seoul must be pretreated so as to recycle the MSWI. There are many pretreatments, three pretreatments (washing, weathering, CO2 aging) of which are selected through the literature review. Through Washing, the value of pH and chloride decrease. The optimal ratio (S/L) and time of Washing treatment is 1 : 10 (S/L) and 60 minutes, respectively. The CO2 aging method compensates the defect of weathering method which is required to react long-period time. After CO2 aging, pH and some Heavy metals decrease. So, We will compare and evaluate pre-treatment methods and we find the best method or new method.

The low quality fresh ginseng was fermented by Phelinus linteus or Hericium erinaceum mycelium. This fermented ginseng was extracted by water at 100℃ or water with ultrasonification at 60℃. Total phenolic compounds was improved by ultrasonification extraction process, compare to conventional water extraction. All extracts enhanced the growth of human B and T cells, showing 2.68 times and 3.43 times higher, respectively, than the control. The secretion of TNF-α and IL-6 from human immune cells was enhanced as 3.53×10-4 pg/cell, 3.40×10-4 pg/cell by adding H. erinaceum mycelium fermented ginseng. H. erinaceum mycelium fermented ginseng yielded higher nitric oxide production from macrophage than Lipopolysaccharides (LPS). The cytotoxicity on human normal kidney cell (HEK293) was as low as 20.5% in adding the maximum concentration of 1.0 mg/ml of fermented ginseng. Generally, the extracts from ultrasonification extraction process showed 10% lower toxicity than that by conventional process. H. erinaceum mycelium fermented ginseng had the highest anticancer activity on human lung cancer and stomach cancer cells as 69.33% and 75.32%, respectively at 1.0 mg/ml. It can be concluded that, in general, H. erinaceum mycelium fermented ginseng has relatively better immune and anticancer activities than P. linteus fermented ginseng. Expecially, the extracts treated with ultrasonification had higher activities than that from conventional extraction process.

As the marine traffic thickens all over the world, the rate of marine casualities is on the increase, Also in Korea the number of the killed and the injured resulting from marine casualities such as ship's collision, increase continuously and the rate of marine casualities in 1992 came to the highest level in the world. The reason of rapid increasing the rte of marine casualities is the mistake of ship's steering in most case. By the way, because the administration of marine traffic is regarded as the belongs of land traffic, the scope of application in laws related to the safety of marine traffic is duplicated or unreasonable. In the view, in case of ship's collision, it is important to know the scope of application in Korean marine traffic laws and to point out the problems companies with them. Therefore, I suggest the improvement of marine traffic laws related to the safety of traffic administration.
