This study was carried out to investigate a adequate strength of nuttient solution in production of marjoram and oregano by hydroponicsl Two herbs were grown for 40days with the strength of 0.5, 1.0, 2.0, and 3.0 dS${\cdot}m^{-1}$ in herb's nutrient solution developed by European Vegetable R & D Center, Belgium. the growth, vitamin C, and essential oil content of marjormam were higher in the treatment of 0.5 dS${\cdot}m^{-1}$ than the other treatments tested. But marjoram growtn with the sstrength of 20. and 3.0 dS${\cdot}m^{-1}$ had the highest mineral contents and essential oil content, respectively. Elevated strength of nutirent solution decreased chlorophyll content. In oregano, the growth was vest in the stength of 0.5, but withered in the strength of 3.0 The chlorophyll content was the lowest in the strength of 0.2dS${\cdot}m^{-1}$, while vitamin C contents had no statistical differences among treatments, Oregano grown with 1.0 dS${\cdot}m^{-1}$had the highest mineral and essential oil content, but the oil yield washighest in the treatment of 0.5 dS ${\cdot}m^{-1}$. In conclusion, the strength of 0.5 dS${\cdot}m^{-1}$ herb's nutrient solution was adequated in production of marjorma and oregano in hydroponicc system. 본 실험은 수경재배시 마죠람과 오레가노의 알맞은 배양액 농도를 구명하기 위하여 실시했다. 배양액은 유럽채소연구센터 허브액을 사용했다. 처리농도는 0.5, 1.0, 2.0, 3.0배액 등 4수준이었고 재배기간은 40일이었다. 마죠람은 지상부 생육, 지하부 생육, 비타민 C,총 정유생산량은 0.5배액에서 가정 조았다. 그러나 무기물함량은 20.배액에서, 정유함량은 3배액에서 좋았으며 엽록소 함량은 고농도에서 감소하였다. 오래가노의 생육 0.5배야ㅐㄱ에서 조았으며, 3.0배액에서는 고사하였다. 엽록소 함량은 2.0배액에서 낮았으나 비타민 C는 이온농도에 영향을 받지 않았다. 무기물과 정유함량은 1.0배액에서 높았으나, 정유생산량은 0.5배액에서 높았다. 이사의 결과로 볼 때 마죠람과 오레가노 수경재배시 적절한 배양액 농도는 허브 배야액 0.5배인 것으로 생각된다.

Background and Objectives The repetitive Transcranial Magnetic Stimulation (rTMS) is generally performed over the course of several weeks, as its theoretical and experimental validity has been identified in repetitive procedures. If short term application of rTMS is proven to be significantly effective, more effective treatment of tinnitus can be expected. This study was conducted to measure the effect of one session of sham rTMS & one real trial of rTMS in chronic unilateral tinnitus patients. Subjects and Method rTMS stimulation of 1 Hz and 100% magnitude was given 1200 times per day to 33 patients with chronic unilateral tinnitus on their left side, between T3 and C3/T5, following the convention of the 10-20 International EEG system. Visual Analogue Scale (VAS) and Tinnitus Handicap Inventory (THI) scores were measured four times-immediately before rTMS, immediately after sham rTMS, immediately after real rTMS and two weeks after real rTMS. Results VAS and THI scores were found to show a tendency of declining. Immediately after real rTMS application, a significant decrease in VAS and THI scores was observed compared to those measured immediately before rTMS (p<0.05). The longer the duration was, the smaller the changes in THI and VAS scores were after a single session of rTMS treatment, a finding that is statistically significant (p<0.05). No significant changes in THI and VAS scores (p>0.05) attributable to the direction of tinnitus were observed. Conclusion A single session rTMS is thought to be a possible adjunctive treatment for tem-porary relief of tinnitus.

複合組織鋼의 母相粒徑과 軸斷面形狀이 破壞擧動에 미치는 影響

吳世旭,姜鎬珉 東亞大學校 1985 東亞論叢 Vol.22 No.1

The weight reduction and reliability, stability of various steel materials used in industrial machinery have become a great importance as industry developes. For this reason a study on dual phase steel has been performed by the reporter with great interest. It was pointed out that fatigue fracture behaviours of MEF dual phase steel were dependent upon a unit of ferrite grain size when the plastic constraint effect and the internal stress were constant. However, when the plastic constraint effect and the internal stress were constant, fracture behaviours of MEF dual phase steel might be expected to depend upon the ferrite grain size and the shape of section. Specimens were prepared the combined microstructures having different size of ferrite grain which has approximatly the constant plastic constraint effect and the constant internal stress through careful heat treatments. Each of tensile specimens and fatigue specimens was conducted by universal testing machine and rotary bending fatigue test machine. They were prepared to be able to apply the stress intensity factor equations(K₁=σ? πℓ. F(?): solid shaft, K₁=k₁.k₂σ? πℓ:hollow shaft). The relationship between fatigue crack length, fatigue crack propagation velocity, stress intensity factor and scanning electron microscope investigation of tensile fracture surface and fatigue fracture surface was investigated during the test. The results of the experiment are as follows. 1. Fracture behaviours of MEF dual phase steel with the constant plastic constraint effect and the constant internal stress depend on great and small size of ferrite grain. It has been found that Hall-petch equation is applied dual phase-poly crystallization. 2. The crack propagation length and number of cycles of hollow specimen and solid specimen approaches nearly and makes a gentle slope in case of small ferrite grain size under low stress level. 3. The difference of fatigue crack propagation velocity is large about the influence of shape of specimen at the same △K value under high stress level and that is approached under low stress level. 4. It can be had for light weighted purpose as use of hollow shaft with MEF dual phase and MEF dual phase steel demands minute ferrite grain size under low stress level. 5. It has been found that the shape of striation changes according to shape difference of specimen. The space of striation is narrow as the ferrite grain size and the stress level are small.

MA저장중 몇가지 싹기름 채소의 저장성 비교

저장중 5가지 싹채소(무, 적무, 적양배추, 알팔파, 브로콜리)의 생체중은 50㎛ LDPE필름으로 밀폐하여 2℃와 8℃ 모두 99%이상 유지되었다. 저장중 포장재 내 이산화탄소 농도는 8℃에서 2℃에서 보다 높았으며 작물별로 무와 적무가 높았다. 산소농도는 이와 정반대로 2℃에서 높게 유지되었고, 무와 적무가 가장 낮은 농도를 보였는데 특히 8℃ 저장 3일째는 3%미만까지 낮아지기도 하였다. 에틸렌 농도도 2℃에 비해 8℃에서 다소 높았으며 작물별로는 알팔파가 0.1ppm으로 기장 낮았고 나머지 4 작물은 작물간 농도차이에 유의성 없이 1ppm미만으로 낮았다. 이취는 산소농도가 가장 낮았던 무와 적무에서 오히려 낮은 수준을 보였으며 온도별로 큰 차이가 없었다. 외관상 품질은 역시 2℃가 8℃보다 높게 유지되었으며, 두 온도 모두에서 무가 기장 높게 유지되었고, 다음으로 적무, 브로콜리, 적양배추, 알팔파 순서였다. 이상의 결과에서 싹채소의 작물간 저장성에 차이를 알 수 있었는데 무와 알팔파의 경우 4~5일의 저장기한의 차이를 보였다. 따라서 싹채소 유통에 있어 직물별 관리가 다르게 실시되어야 할 것이라 생각된다. This study was conducted to compare the storability of some sprout vegetables; alfalfa, broccoli, radish, red-cabbage, and red-radish, packed with 50 low density polyethylene (LOPE) film in MA storage. Most of all 5 different sprout vegetable crops maintained the fresh weight higher than 99% until 10 days storage at 2 and 8℃. The carbon dioxide concentration in packages was higher at 8 than at 2℃. It was higher in radish and red-radish sprouts than other crops. As the oxygen concentration showed opposite trends to carbon dioxide, that of radish and red-radish sprouts decreased more than 3% after 3 days in 8 storage. Ethylene concentration in the packages of alfalfa was 0.1 ppm, significantly higher than other four crops with less than 1.0 ppm. Temperature treatment, however, did not influence the ethylene concentration in packages. The radish and red-radish sprouts, with lowest oxygen concentration in package, showed lowest off-flavor compared to the others. The visual quality of these sprouts in packages showed higher at 2℃ than at 8℃ and was maintained the highest in radish sprouts, followed by red-radish, broccoli, red-cabbage, and alfalfa sprouts in that order. In conclusion, as the sprout vegetables have different shelf-life, of which radish was 4~5 days longer than that of alfalfa, the distributed condition of sprout vegetables should be differently controlled according to kinds of crops.
