In this work the dynamic heat transfer occurring in a cable penetration fire stop system built in the firewall of nuclear power plants is three-dimensionally investigated to develop a test-simulator that can be used to verify effectiveness of the sealants. Here was carried out an experiment to observe the heat transfer in the cable penetration fire stop system made of DOW CORNING products. The dynamic heat transfer occurring in the fire stop system is formulated in a parabolic partial differential equation subjected to a set of initial and boundary conditions. And it was modeled, simulated, and analyzed. The simulation results were illustrated in three-dimensional graphics and were compared with experimental data. Through the simulations, it was shown clearly that the temperature distribution was influenced very much by the number, position, and temperature of the cable streams. It also was found that the dynamic heat transfer through the cable streams was one of the most dominant factors, and the feature of heat conduction could be understood as an unsteady-state process. It is certain that these numerical results are useful for making a performance-based design for the cable penetration fire stop system.

BACKGROUND/OBJECTIVES: This study aims to determine contribution of meal frequency, self-efficacy for healthy eating, and availability of healthy foods towards diet quality of adolescents in Kuala Lumpur, Malaysia. SUBJECTS/METHODS: This study was conducted among 373 adolescents aged from 13 to 16 years old. Diet quality of the respondents was assessed using the Healthy Eating Index for Malaysians. Meal frequency, self-efficacy for healthy eating, and availability of healthy foods were assessed through the Eating Behaviours Questionnaire (EBQ), self-efficacy for healthy eating scale, and availability of healthy foods scale, respectively. RESULTS: The majority of the respondents (80.7%) were at risk of poor diet quality. Males ($mean=34.2{\pm}8.2%$) had poorer diet quality than females ($mean=39.9{\pm}9.0%$) (t = -5.941, P < 0.05). Malay respondents ($mean=36.9{\pm}8.7%$) had poorer diet quality than Indian respondents ($mean=41.3{\pm}10.0%$) (F = 2.762, P < 0.05). Age (r = 0.123, P < 0.05), self-efficacy for healthy eating (r = 0.129, P < 0.05), and availability of healthy foods (r = 0.159, P < 0.05) were positively correlated with the diet quality of the respondents. However, meal frequency was not correlated with the diet quality of the respondents. Multiple linear regression analysis showed that being a male, being a Malay, low self-efficacy for healthy eating, and low availability of healthy foods contributed significantly towards poor diet quality among respondents. CONCLUSIONS: In short, sex, ethnicity, self-efficacy for healthy eating, and availability of healthy foods were associated with diet quality among adolescents. Health practitioners should take into consideration of differences in sex and ethnicity during implementation of nutrition-related intervention programs. Self-efficacy for healthy eating and availability of healthy foods should be included as important components in improving diet quality of adolescents.

This study sought to find out the level of perception of the effect on women's physical, mental, socio-culture health of the artificial abortion. The research design was a descriptive correlational study and selected by convenient sampling. The subjects were 510 female and male adults who live in Seoul, Korea. Data were collected from 20th September, 1999 to 28th October, 1999. The data were analyzed through the SPSS program by use of frequency, percentage, t-test, ANOVA and Scheffe test as a post hoc contrast, $x^2$-test, Pearson correlation coefficient and stepwise multiple regression. The results of the study are as follows. 1. The subject who experienced artificial abortion was 24.3% and 468% of these had experienced repeated artificial abortion. 54.4% was using the contraceptives and there was a significant difference in the contraceptives between that women wish to use and that women are really using. 2. For the opinion on the artificial abortion, 77.3% of respondents was pro-abortionists and the most acceptable reasons of pro-choice were" In case of unmarried" and "For the women's health". 3. On the whole, the subjects perceived that artificial abortion had a negative effect on the women's health, especially, on the women's mental health. Among the items, 'guilty feeling about the baby' was the highest. 4. The related factors to the level of perception of the effect on women's health of the artificial abortion were in sex, age, occupational status, marital status, educational level, the number of children, abortion history, contraceptives women use, the frequency of the consideration on the problem of artificial abortion and the position toward abortion such as pro or anti. The main influencing factors on the level o0f perception were artificial abortion history, occupational status and the frequency of the consideration on the problem of artificial abortion. Theses factors explained 35% of total variance of the level of perception 5. The variables related to the experience of artificial abortion were age, occupational status, marital status, religion, educational level, the number of children and whether women practice contraceptives or not.

Nicht nur in Philosophie sondern auch im Bereich der meinsten Geisteswissenschaften $best{\ddot{a}}rkt$ sich die Gewichtigkeit des Spielbegriffs immer mehr. Aus diesem Grund wird 'Spiel' in den $vielf{\ddot{a}}ltigen$ Wissenschaftsbereichen, in $vielf{\ddot{a}}ltiger$ Weise definiert, und diese Definitionen sind im Gebrauch auch in $vielf{\ddot{a}}ltiger$ Weise. Aber trotz dieser mit Spiel $zusammenh{\ddot{a}}ngenden$ '$Vielf{\ddot{a}}ltigkeiten$' liegt immer eine identische Voraussetzung am Boden der Definitionen oder Theorien des Spiels, und das ist nichts anderes als, dass Spiel ausnahmslos eine Vertieftsein-$T{\ddot{a}}tigkeit$ ist. Anders gesagt, dass es kein Spiel gibt, in dem man sich nicht $v{\ddot{o}}llig$ aufgeht. Aber diese Ansicht ist vorwiegend nur im Abendland in Geltung, und deswegen ist es sehr bedenklich, ob man das auch auf dem Morgenland gleichfalls zutreffen $k{\ddot{o}}nnte$. Grund $daf{\ddot{u}}r$ ist, dass, weil das traditionelle $Lebensgef{\ddot{u}}hl$ nicht in einem Tage gebildet worden ist, $l{\ddot{a}}sst$ sich es nicht vermeiden, dass dieses $Lebensgef{\ddot{u}}hl$ auf alles, was mit dem Leben Zusammenhang steht, einen unmittelbaren Einfluss $aus{\ddot{u}}bt$. Dann kann man sagen, dass das sich $nat{\ddot{u}}rlich$ in der Ansicht zum Spiel widerspiegelt. Aus diesem Urteil wird man in dieser Arbeit den Vertieftseinsbegriff und den Verfremdungsbegriff gegeneinander stellen, und folglich, wenn man die 'Verfremdung' $f{\ddot{u}}r$ einen sonstigen Charakter des Spiels erachten kann, muss man sie auch in Rechnung ziehen, falls man Spielbegriff studieren will.

Ist der Emotivismus eine $mi{\ss}lungene$ Theorie? Nach der Meinung von Jesse Prinz ist es nicht so. Auf der Humeschen Tradition stehend behauptet er, $da{\ss}$ ein moralisches Urteil ohne das Sentiment von Billigung oder $Mi{\ss}billigung$ nicht zustandekommen kann. Ihm zufolge ist Emotion nicht allein mit moralischen Urteilen verbunden, sondern auch eine notwendige und hinreichende Bedingung $daf{\ddot{u}}r$. Der Grund dessen, warum der Emotivisums nicht ${\ddot{u}}berzeugend$ erschien, liegt darin, $da{\ss}$ $f{\ddot{u}}r$ diesen die Verbindung von Emotion und Moral nur auf den $Gef{\ddot{u}}hlsausdruck$ $beschr{\ddot{a}}nkt$ bleibt. Zwar stellt das moralische Urteil Sentiment dar, aber das bleibt eben nicht als ein $blo{\ss}$ $Gef{\ddot{u}}hlsausdruckendes$. Denn die $Moralit{\ddot{a}}t$ ist nicht die einfache Projektion eines subjektiven Zustandes, vielmehr konstruiert die emotionale Reaktion von Billigung oder $Mi{\ss}billigung$ das moralische Urteil. Daher muss der projektistische Gesichtspunkt des expressionistischen Emotivismus modifiziert werden, so $da{\ss}$ der oft dem Emotivismus kritisch zugeschriebene moralische Nihilismus zu ${\ddot{u}}berwinden$ ist. In diesem Zusammenhang $schl{\ddot{a}}g$ Prinz den konstruktiven Sentimentalismus vor, der als eine hybride Theorie des Moralbegriffs von 'biologiscehn Tatsachen' und 'sozialer Konstruktion' darauf zielt, im moralischen Leben eine Stelle auszumanchen, wo Evolution und Kutur zueinander zusammentreffen $k{\ddot{o}}nnen$.

The Precambrian granite, and the Yuli group and the Hyeondong gneisss complex are studied to unravel the metamorphic history of the northeastern Sobaeksan massif. The Hongjesa granite, emplaced at 650-$700^{\circ}C$ and $3{\pm}1$ kbar, has been altered at 310-$568^{\circ}C$. Not only the chloritization of biotite but also the sericitization and saussuritization of plagioclase occur at the subsolidus stage. Biotites of the Hongjesa granite vary in their Al, Fe and Mg contents through dioctahedral and tschermakitic substitutions during the subsolidus stage. Secondary muscovites from biotite and feldspars are enriched in their Si and Mg+Fe contents through tschermakitic and trictahedral substitutuions. The metamorphic pressures and temperatures estimated from the Hyeondong gneiss complex are 3.6-6.6 kbar and 593-$718^{\circ}C$, respectively. Local migmatization producing the cordierite-bearing assemblage occurs in the Hyeondong gneiss complex. The Gibbs' method applied to the assemblage of garnet+biotite+plagioclase+quartz in banded gneiss suggests a complex P-T history of the Hyeondong gneiss complex.

Objective: Inbreeding depression of reproduction is a major concern in the conservation of native chicken genetic resources. Here, based on the successful development of strongly inbred (Sinb) and weakly inbred (Winb) Langshan chickens, we aimed to evaluate inbreeding effects on reproductive traits and identify candidate genes involved in inbreeding depression of reproduction in Langshan chickens. Methods: A two-sample t-test was performed to estimate the differences in phenotypic values of reproductive traits between Sinb and Winb chicken groups. Three healthy chickens with reproductive trait values around the group mean values were selected from each of the groups. Differences in ovarian and hypothalamus transcriptomes between the two groups of chickens were analyzed by RNA sequencing (RNA-Seq). Results: The Sinb chicken group showed an obvious inbreeding depression in reproduction, especially for traits of age at the first egg and egg number at 300 days (p<0.01). Furthermore, 68 and 618 differentially expressed genes (DEGs) were obtained in the hypothalamus and ovary between the two chicken groups, respectively. In the hypothalamus, DEGs were mainly enriched in the pathways related to vitamin metabolism, signal transduction and development of the reproductive system, such as the riboflavin metabolism, Wnt signaling pathway, extracellular matrix-receptor interaction and focal adhesion pathways, including stimulated by retinoic acid 6, serpin family F member 1, secreted frizzled related protein 2, Wnt family member 6, and frizzled class receptor 4 genes. In the ovary, DEGs were significantly enriched in pathways associated with basic metabolism, including amino acid metabolism, oxidative phosphorylation, and glycosaminoglycan degradation. A series of key DEGs involved in folate biosynthesis (gamma-glutamyl hydrolase, guanosine triphosphate cyclohydrolase 1), oocyte meiosis and ovarian function (cytoplasmic polyadenylation element binding protein 1, structural maintenance of chromosomes 1B, and speedy/RINGO cell cycle regulator family member A), spermatogenesis and male fertility (prostaglandin D2 synthase 21 kDa), Mov10 RISC complex RNA helicase like 1, and deuterosome assembly protein 1) were identified, and these may play important roles in inbreeding depression in reproduction. Conclusion: The results improve our understanding of the regulatory mechanisms underlying inbreeding depression in chicken reproduction and provide a theoretical basis for the conservation of species resources.

Plant parasitic nematodes are causing significant damage in crop production. There is a need to develop eco-friendly nematicide that reduces the damage of nematode and has little effect on the environment and human. In this study, we have isolated a substance having nematicidal activity from Ginkgo biloba L. outer seedcoat. Studies of G. biloba L. outer seedcoat are insufficient compared to the seed and leaves due to their odor and toxicity. The dried G. biloba L. outer seedcoat was extracted with dichloromethane:methanol (1:1) and fractionated into hexane, ethyl acetate and H₂O. Four steps TLC were performed from EtOAc fraction to purely isolate GB4-3 with nematicidal activity. To compare nematicidal activity, G. biloba L. seedcoat methanol extract and purified GB4-3 were investigated in terms of treatment concentration and time. As a result, the nematicidal activity increased with concentration and time. In the place treated with 20 ㎍/mL of crude G. biloba L. seedcoat MeOH extract, strong activity appeared after 12 hours, and 46% nematicidal activity shown after 18 hours. About 69% of nematicidal activity was confirmed in the place where GB4-3 purified from outer seedcoat was treated with 20 ㎍/mL, and the possibility of development as nematicide was very high. This study could be used as a basic data for the development of a nematode preparation from G. biloba L. outer seedcoat.
