  • Flow through a scaled horizontal axis marine current turbine was numerically simulated after validation and the turbine design was optimized. The computational fluid dynamics (CFD) code Ansys-CFX 16.1 for numerical modeling, an in-house blade element momentum (BEM) code for analytical modeling and an in-house surrogate-based optimization (SBO) code were used to find an optimal turbine design. The blade-pitch angle (${\theta}$) and the number of rotor blades (NR) were taken as design variables. A single objective optimization approach was utilized in the present work. The defined objective function was the turbine's power coefficient ($C_P$). A $3{\times}3$ full-factorial sampling technique was used to define the sample space. This sampling technique gave different turbine designs, which were further evaluated for the objective function by solving the Reynolds-Averaged Navier-Stokes equations (RANS). Finally, the SBO technique with search algorithm produced an optimal design. It is found that the optimal design has improved the objective function by 26.5%. This article presents the solution approach, analysis of the turbine flow field and the predictability of various surrogate based techniques.

  • Tocotrienol $(T_3)$ and tocopherol (T) are well-known antioxidant vitamin E isomers that are enriched in rice bran, most of which is removed during polishing process. To verify the polishing-dependent fractional content of tocotrienol and tocopherol, harvested brown rice of 4 cultivars were polished by 4.0, 6.4, 8.0, 9.6, and $12\%$ (w/w) and resultant bran powder and rice were used for $T_3$ and T analysis. Polishing degree affected bran $T_3$ content in that bran polished by $6.4\%$ exhibited highest $T_3$ content compared to other polishing degrees except in cv. Chucheongbyeo which showed similar $T_3$ content from 4.0 to $8.0\%$ polishing. In case of tocopherol, bran polished by $8.0\%$ exhibited highest T content in all tested cultivars. In general, $T_3$ distributed in higher quantity in exterior i.e., in less polished bran, while T showed relatively less decrease with enhanced polishing degree. Consequently, total vitamin E content in bran as calculated by the summation of $T_3$ and T became less dependent on polishing degree in that bran polished between 6.4 to $9.6\%$ exhibited no statistical differences. The rice of cv. Chuchongbyeo, remained after polishing, exhibited similar vitamin E content up to $6.4\%$ polishing, above which significant vit E loss could be observed. These results suggest that polishing less than $6.4\%$ is desirable to minimize the loss of tocotrienols and tocopherols during polishing.

  • Dans l'histoire du $th{\acute{e}}{\hat{a}}tre$ $cor{\acute{e}}en$, la position de Chae yoon-il est $tr{\grave{e}}s$ $particuli{\grave{e}}re$. Il a $consacr{\acute{e}}$, dans ses $carri{\grave{e}}res$ de la mise en $sc{\grave{e}}ne$, toute son ${\acute{e}}nergie$ au $th{\acute{e}}{\hat{a}}tre$ sans jamais $fl{\acute{e}}chir$ contre le pouvoir dictatorial. Un critique a dit que son $th{\acute{e}}{\hat{a}}tre$ est semblable au $th{\acute{e}}{\hat{a}}tre$ de la $cruaut{\acute{e}}$. Pourtant, dans la mesure $o{\grave{u}}$ il respecte le texte dramatique, et que son $th{\acute{e}}{\hat{a}}tre$ a des tendances de la politique et qu'il oriente l'engagement du spectateur, il est certain que son $th{\acute{e}}{\hat{a}}tre$ est loin du $th{\acute{e}}{\hat{a}}tre$ de la $cruaut{\acute{e}}$. Ses $proc{\acute{e}}d{\acute{e}}s$ de la mise en $sc{\grave{e}}ne$ sont $tr{\grave{e}}s$ divers et il n'y a pas de $coh{\acute{e}}rences$ au niveau des styles dramatiques. $Malgr{\acute{e}}$ cela, nous pouvons trouver son $originalit{\acute{e}}$ de la mise en $sc{\grave{e}}ne$ dans la rencontre avec Lee hyun-wha. Le metteur en $sc{\grave{e}}ne$ ${\acute{e}}tablit$ son $esth{\acute{e}}tique$ $th{\acute{e}}{\hat{a}}trale$ en montant sur $sc{\grave{e}}ne$ de cinq $pi{\grave{e}}ces$ de Lee hyun-wha. Alors, en effet qu'est-ce que $l^{\prime}esth{\acute{e}}tique$ de la mise en $sc{\grave{e}}ne$ de Chae yoon-il produite par les ${\oe}uvres$ $th{\acute{e}}{\hat{a}}trales$ de Lee hyun-wha? Dans les $pi{\grave{e}}ces$ de Lee hyun-wha, il y a beaucoup de codes symboliques de la violence sexuelle comme le sadisme et le masochisme. L'implusion sexuelle $cach{\acute{e}}e$ dans le subconscient des personnages s'entrecroise avec le $m{\acute{e}}canisme$ du pouvoir politique. Alors, les abus sexuels et les mauvais traitements sur le corps deviennent une sorte de torture. L'expression cruelle des langages $sc{\acute{e}}niques$ n'est autre que la $r{\acute{e}}volte$ contre la $r{\acute{e}}alit{\acute{e}}$ actuelle de la politique. Son $th{\acute{e}}{\hat{a}}tre$ de torture est donc une sorte de $m{\acute{e}}canisme$ de la catharsis pour dissiper le cauchemar et l'inconscient noir. La fantasie sexuelle construite par le monde inconscient de l'auteur dramatique $s^{\prime}{\acute{e}}panouit$ dans le $th{\acute{e}}{\hat{a}}tre$ de Chae yoon-il qui $r{\hat{e}}ve$ toujours l'esprit de la $libert{\acute{e}}$. Une des convictions dramatiques du metteur en $sc{\grave{e}}ne$, c'est que le $th{\acute{e}}{\hat{a}}tre$ tout d'abord doit ${\hat{e}}tre$ choquant. Il dit : "l'art doit ${\hat{e}}tre$ ${\grave{a}}$ la fois ${\acute{e}}mouvant$ et bouleversant. Cependant, dans la mesure $o{\grave{u}}$ le film ou la $t{\acute{e}}l{\acute{e}}vivion$ fait aujourd'hui une vive impression aux spectateurs, la part $donn{\acute{e}}e$ au $th{\acute{e}}{\hat{a}}tre$ est le choc." Pour donner le choc aux spectateurs, le style de la torture est $tr{\grave{e}}s$ utile. $L^{\prime}esth{\acute{e}}tique$ $th{\acute{e}}{\hat{a}}tral$ du metteur en $sc{\grave{e}}ne$ respecte essentiellement l'intention de l'auteur. $N{\acute{e}}anmois$, le respect sur l'original ne se $d{\acute{e}}range$ pas $l^{\prime}interpr{\acute{e}}tation$ de son propre $id{\acute{e}}e$. Dans l'insistance de la torture, l'analyse rituelle sous la base du choc, il projecte le symbole $arch{\acute{e}}typal$ sur $sc{\grave{e}}ne$. Bien $s{\hat{u}}r$, il renforce le $caract{\grave{e}}re$ de la politique dans le $th{\acute{e}}{\hat{a}}tre$ de torture pour inviter des spectateurs de l'engagement. D'ailleurs, il y a l'aspect d'absurde dans le $th{\acute{e}}{\hat{a}}tre$ de torture qui insiste des violences ${\grave{a}}$ travers les langages $sc{\acute{e}}niques$ comme le $m{\acute{e}}tal$ froid, parce que le metteur en $sc{\grave{e}}ne$ $consid{\grave{e}}re$ que $l^{\prime}{\hat{e}}tre$ humain vit dans l'absurde.

  • Recently the adenosinetriphosphates have massive highlight due to their high energy source for treat and maintained all the cell mechanism in the individual. When the A. T.P. release the terminal phosphate, produces about 8,000 calories instead of the 3,000 calories from common chemical bonds. The high energy-P bond enables the cell to accumulate a great amount of energy in a very small space and the keep it ready to be used as soon as it is needed. The presence of A.T.P. explains why some important cellular functions such as nerve conduction can go on for some time even with complete inhibition of respiration. In recent years the A.T.P. were used in many clinical field with good effects. In this report was used A.T.P. 20mg+Vit $B_1$ 50mg+20% Dextrose 20㏄ through intravenousely for E.N.T. neurologic patient, such as neurogenic hearing impairment, tinnitus, dizziness, soft palate paralysis. By the injection 40% of neurogenic hearing impairment patients were improved and 62% tinnitus patients were improved and all the soft palate paralysis patient were completely recovered.

  • This study was designed to find out the nutritional defect of general Korean diet and the effective way of nutritional supplementation. Seventy weanling Sprague-Dawley male rats weighing 51.8$\pm$0.9g were blocked into ten groups and fed ten different diets ad libitum for eight weeks: Standard groups(st gp) was given 72% sugar-20% casein diet: Cereal-vegetable group(c-v gp) was fed cereal-vegetable diet(c-v diet) composed of rice, barley, soybean, spinach and cabbage: the other eight groups were fed c-v diets supplemented with casein, vitamin $B_{2}$, calcium, vitamin A, vitamin B2 and A, vitamin A and calcium, vitamin $B_{2}$ and calcium, vitamin A and $B_{2}$and calcium, respectively, on the basis of each nutrients content of standard diet. The results were as follows: 1. Food intakes and body weight gains in all the experimental groups were significantly lower than st gp. Among experimental groups, casein gp and vit B2 gp tended to gain more body weights than c-v gp. 2. Through all the experimental period, F.E.R., pp.E.R., and NDPcal% did nod show significant differences among all the experimental groups and st gp. 3. The weights of liver, kidney, and gastrocnemius were significantly lower in all the experimental groups as compared with st gp. But brain and sex organ weights did not show differences among all the groups. 4. Nitrogen contents of total carcass, liver, and gastrocnemius in all the experimental groups tended to be increased as compared with st gp, and among experimental groups, they tended to be increased by casein supplementation and decreased by ca supplementation. 5. Apparent nitrogen digestibility, urinary and fecal nitrogen excretion, the amount of nitrogen retained, and N.P.U. did not show any significant differences among all the groups. 6. Serum total protein concentrations did not show any significant differences among all the groups.

  • Pour Kierkegaard la condition de l'homme naturel est tragique. $D^{\prime}{\hat{e}}tre$ $s^{\prime}{\acute{e}}veiller$, ${\hat{e}}tre$ ignorant et $d{\acute{e}}nier$ sur son vrai ${\hat{e}}tre$, tous causent le $d{\acute{e}}sespoir$. En plus l'homme ne peut avoir une conviction sur son bonheur $jusqu^{\prime}{\grave{a}}$ la mort. Donc sa $th{\acute{e}}orie$ du bonheur ne se base pas sur le bonheur. Tous le monde vit dans une situation $o{\grave{u}}$ il y a une distance entre $l^{\prime}{\hat{e}}tre$ $pr{\acute{e}}sent$ et son vrai ${\hat{e}}tre$. La vie ${\grave{a}}$ la perspective ${\acute{e}}thique$ s'apparaît comme se diriger vers son vrai ${\hat{e}}tre$ et ceci signifie $d^{\prime}{\acute{e}}tablir$ son ${\hat{e}}tre$ $int{\acute{e}}rieur$ en s'echappant la vie $esth{\acute{e}}tique$ qui est la vie sensitive et directe, et aussi faire s'identifier son ${\hat{e}}tre$ $ext{\acute{e}}rieur$ ${\grave{a}}$ son ${\hat{e}}tre$ $int{\acute{e}}rieur$. Le $p{\acute{e}}ch{\acute{e}}$ signifie la $s{\acute{e}}paration$ de son vrai ${\hat{e}}tre$, cela est la source de tout mal. L'obtention parfait de $l^{\prime}{\hat{e}}tre-soi$ exisge ${\hat{e}}tre$ en $pr{\acute{e}}sence$ devant l'Asolu(Dieu) en tant qu'individu unique, et s'accorder avec l'Absolu. Mais du fiat $m{\hat{e}}me$ que ceci est impossible pour tous, tout le monde ne peut vivre qu'ayant un peu de $p{\acute{e}}ch{\acute{e}}$. Donc l'aspect de la vie ${\acute{e}}thique$ s'apparaît une vie dynamique qui $d{\acute{e}}passe$ $soi-m{\hat{e}}me$ sans cesse. En contradiction qu'avec l'analyse sur $l^{\prime}{\hat{e}}tre$ $pr{\acute{e}}sent$ qui est si tragique, la vertu de cette vie ${\acute{e}}thique$ est si optimiste. Elle est l'amour. Cet amour est $tr{\acute{e}}s$ excellent qui $d{\acute{e}}passe$ toute la vertu ${\acute{e}}thique$. En $v{\acute{e}}rit{\acute{e}}$ pour Kierkegaard, bien que le salut $lui-m{\hat{e}}me$ sera donner par la foi, le principe de cet amour est l'unique vertu qui ammene l'homme vers la foi et vers le salut. C'est pourquoi son ${\acute{e}}thique$ est essentiellement s'apparaît 'une ${\acute{e}}thique$ de l'amour', et la recherche sur cet amour, son principe et son aspect reste comme uneque $t{\hat{a}}che$ de $l^{\prime}{\acute{e}}thique$.

  • Vitamin E, consisting of tocotrienols ($\textrm{T}_3$) and tocopherols ($\textrm{T}$) is well-known nutraceutical compound for its antioxidant, anticancer and cholesterol-low-ering activity. The contents of alpha ($\alpha\textrm{-}$), beta ($\beta\textrm{-}$), gamma ($\gamma\textrm{-}$) and delta ($\delta\textrm{-}$) tocotrienols and tocopheyols in some Korean crop seeds were evaluated by using HPLC after saponification. Among tested crops, total 73 contents (mg/110g) were purple perilla 25.06, barley 4.50, corn 3.54, iris 3.04, adlay 2.58, safflower 0.12. Other crops including 5 soybean cultivars, kidneybean, sunflower and perilla contained no tocotrienols. Regarding $\textrm{T}_3$ isomers, $\beta\textrm{-}$$\textrm{T}_3$ were rut observed in adlay and corn, and $\delta$-$\textrm{T}_3$ were not in iris aid purple perilla, while safflower exhibited no detectable $\alpha\textrm{-}$, $\beta\textrm{-}$ and $\delta\textrm{-}$$\textrm{T}_3$. Total T contents (mg/100g) were high in iris (51.82), perilla (40.90), soybean (34.11), sunflower (20.88), and they all contained all $\alpha\textrm{-}$, $\beta\textrm{-}$, $\gamma\textrm{-}$ and $\delta\textrm{-}$ tocopterol isomers. Total Vit E contents (T + $\textrm{T}_3$, mg/100g) were iris 54.86, purple perilla 41.80, perilla 40.90, soybean 34.11, sunflower 20.88, safflower 14.73, corn 11.49, evening-primrose 10.07, barley 7.48, adlay 6.24 and kidneybean 5.27.

  • Twenty four Hanwoo cull cows were assigned to 2 groups, control and melengerol acetate(MGA)+selenium supplement containing vitamin E(SeE), based on the parity(6.5±1.7 birth) and body weight (493.17±55.61kg), and the experiment was conducted to establish the reasonable fattening method of cull cows for 240 days. Average daily body gains during 240 days were 0.51kg and 0.63kg in control and MGA+SeE, respectively(P<0.10). DDMI/ADG of MGA+SeE group improved compared to control group(P<0.05). Therefore, supplementation of MGA+SeE in concentrates may accelerate both of the growth rate and feed efficiency in Hanwoo cull cows. MQI from MGA+SeE was more developed based on the larger rib-eye area and thinner backfat thickness in carcass than that from control. Marbling score for MGA+SeE tended to increase compared to control. Dietary Se supplementation significantly affected muscle Se concentration in longissimus dorsi meat of MGA+SeE group(P<0.05). Similar results to Se were obtained from α-Tocoperol concentration. During 7 days of simulated retail display, accumulations of thiobarbituric acid reactive substances(TBARS) concentration in beef was greater(P<0.05) in control than in supplemented cows. These results supported the hypothesis that supplementation of MGA+SeE improve the growth performance and carcass grade both by the growth stimulating effect of MGA+SeE and by preventing the oxidation of the longissimus dorsi muscle in Hanwoo cull cows.

  • Objectives : Gimun-chimbub(Jimen-zhenfa) is the method of needling which is based on Gimun-hak (Jimen-xue), and it is the most excellent method of needling than any other methods. In spite of the superiority of Gimun-chimbub(Jimen-zhenfa), there are few documents which explain it in details. The purpose of this study is to make clear principle of Gimun(Jimen) & apptication of Gimun-chimbub(Jimen-zhenfa) so many clinicians can make good use of it. Methods : Through investigation of many documents concerning Gimun(Jimen), Gimun-chimbub(Jimen-zhenfa) and Bosa(buxie), the author first explained principle of Gimun(Jimen) and then made clear how to apply it in needling and how to perform Bosa(buxie). Conclusions : 1. Gimun-hak(Jimen-xue) is constituted combinations of infinite change of Chen-Gy-In Samje(Tianrendi Sancai) and Hado lakse(Hetu Luoshu). Gimun-hak(Jimen-xue), is the study which shows us the change of space time e- ntangling at once, and it is applied to troublous times and critical situations. Gimun-chimbub(Jimen-zhenfa) combines of the method of needling with the time when Chen(Tian) opens and closes. So according to each cases, doctor must consider the adequate time. For example, in case of acute disease, the first day when the patient got ill is ta - ken. In case of chronic disease, the day when the patient came to see a doctor is taken. In Gimun-chimbub(Jimen-zhenfa), first it uses Jik-Sa-Mun(zhishimen) which can ac - cept Chen-Gi(tianqi). When needling, doctor must find the accurate acu-points and perform Bosa(buxie). Finally it uses Saeng-Mun(shengmen) which stirs up the vit - ality. Using Saeng-Mun(shengmen) decreases the rate of relapse of diseases.

  • This study is intended to reveal the nutritional realities of school children due to their box lunch. The samples were chosen at random from the third grade to the sixth grade children in an elementary school in Seoul : 122 male and 111 female children, 233 children in all. among the subjects, 44.3% have a family of four, 34.3% have over 500,000 won of family income a month, and 44.3% of their mothers graduated from a high school. The average intake of calories is 573.6 Kcal, and the ratios of the calory intakes to the recommended amounts are 90.6% in the third grade children and from the fourth grade to the sixth grade, 79.5% in the male children and 82.9% in the female children. The average consumption of protein is 21.0g and the ratio of animal protein is 41.4%. the ratio of energy yield nutrients is 67.4% : 14.5 : 18.0 (carbohydrate : protein " fat). Considering the recommended amounts, the intake of protein is enough; the consumption of vit, A, thiamine, niacin are appropriate;and the intake of calories, Riboflabin and ascorbic acid, calcium, iron are deficient. Even though there is no significant difference between the socioeconomic factors (the standard of education of the subjects' mothers and family income0 and the intakes of calories and protein, there is a tendency that the consumption of protein intake si more abundant in the middle class than in any other class. The subjects' distribution of the physical growth index, is as follows; A (6.9%), B(19.3%), C(48.5%), D(13.7%) and E (11.6%). As the subjects' intake of calcium increases, the weight shows significant improvement (p<0.001). As the consumption of calories increases, the physical development shows significant improvement (p<0.05), and the weight shows significant increase (p<0.001).
