Objective: Piglet pre-weaning mortality is an important variable indicating the efficacy of farrowing management and animal well-being during lactation. The present study determined the association of newborn traits measured soon after birth with piglet pre-weaning mortality and growth. Methods: In total, 805 piglets born from 57 multiparous sows were investigated. Their blood oxygen saturation, blood glucose and rectal temperature at 24 h after birth (RT24h) were monitored. Birth order, sex, skin color, integrity of the umbilical cord, attempts to stand and birth intervention were monitored. Piglets were weighed at day 0, 7, and 21 to evaluate average daily gain (ADG). Results: Piglet pre-weaning mortality for lactation period was 12.6% and cumulative mortality during the first 7 days of age was 8.6%. A higher proportion of piglets with pale skin color died compared to piglets with normal skin color (26.7% vs 7.7%, p<0.001). A higher (p<0.001) proportion of piglets that attempted to stand after 5 min (38.5%) died compared to piglets that attempted to stand within 1 min (6.3%) after birth. Piglet body weight at birth ($BW_B$), blood glucose and the number of piglets born alive (BA) were correlated with ADG (p<0.05). Piglets with $BW_B$ <1.30 kg had higher (p<0.001) mortality rate than piglets with $BW_B{\geq}1.80 kg$ (19.0% vs 3.3%) and piglets with $BW_B$ 1.30 to 1.79 kg (4.0%). Piglet with RT24h <$37.0^{\circ}C$ had higher (p<0.001) mortality rate (86.2%) than piglets with RT24h >$38.5^{\circ}C$ (3.9%). Conclusion: Low $BW_B$ and low RT24h compromise piglet survival during the lactation period in the tropical conditions. Piglets in the litters with a high BA, low $BW_B$ and low blood glucose have reduced ADG.

These experiments were conducted to investigate the effects of Cervi cornu extract on lymphocyte blastogenesis in spleen, thymus, lymph node, born marrow cells of Balb/c mouse, haemagglutination reaction against sheep red blood cell (SRBC), plaque forming cell (PFC) assay against SRBC and IL-2 production. Lymphocyte blastogenesis was determined by $[^3H]-thymidine$ incorporation. According to the lymphcoyte blastogenesis test on the immune cell. Ceriv cornu extrat was showed a potent mitogenic activity on the spleen and lymph node cells, but had mild mitogenic activity on the thymus and born marrow cells. Mitogenic active component of Crevi cornu extract was identified to be materials where molecular weights are higher than 5,000 by membrane filteration method. Cervi cornu extrat was shown to increase mitogenic effect on the lipopolysaccharide (LPS)-stimulated spleen cells significantly, but decrease mitogenic effect on the Con A stimulated spleen cell at the concentration 0.3%, 1% and 3%. Ceriv cornu extract didn't show to be haemagglutination reaction and showed to inhibit the Con A-induced haemagglutination reaction against SREC. Result of SRBC-PEC test. Ceriv cornu extract significantly increase the number of PEC at the concentration of 0.1% and 1%. When IL-2 or IL-4 production was determined by proliferation of CTLL-2 cells. Ceriv cornu extract was not shown to stimulate the production of IL-2. From the above results, it is shown that Ceriv cornu extract increased antibody production by B cells, but nor IL-2 production by helper T cells.

This study examined the relationships between socio-demographic background variables, parent-child differentiation, marital stability, and psychological well-being in 382 eco-boomer married women (born in 1979-1992) whose mothers were born in 1955-1963. As a result, the higher the average monthly contact frequency with the mother, the greater the intimacy (connectivity) with the mother. The higher the number of years of marriage, the lower the marriage stability, the higher the education level, and the higher the average household income were related to the higher the self-acceptance. In addition, compared to women in single-income families, married women who receive help raising their children from their mothers did not form reliable relationships with others or show satisfaction compared to women who do not receive the assistance. Those who were well connected with their mother (or had high intimacy) had higher marriage stability, and those with higher marriage stability had higher psychological well-being. They also had better relationships with other people when married women had a higher level of parent-child differentiation.

The purpose of this paper is to reveal how Christian ideas are indicative of Theocentricity (God-centeredness) whereas Daesoon Jinrihoe ideas are indicative of anthropocentrism (human-centeredness). This task will be accomplished through comparing incarnation theology from the Bible and The Canonical Scripture. Both Christianity and Daesoon Jinrihoe affirm that there is another world above the human world that cannot be touched by human sense organs. And they both acknowledge a supreme deity who exists in that above world. Furthermore, they share the notion that the supreme deity came into the human world after being born from a woman. Where they depart is that in Christianity, this belief refers to Jesus, the one who was born in Bethlehem more than 2,000 years ago, whereas in Daesoon Jinrihoe, it is instead believed to be Kang Jeungsan (secular name: Kang Il-Sun) who was born in Gaekmang Village in Korea more than 100 years ago. The Christian God came to the human world as an atonement for humanity and died on the cross; The God of Daesoon Jinrihoe came to the human world to help mankind settle all enmities. To this end, he traveled through the realms of Heaven, Earth, and Humanity, to recalibrate the faulty Degree Numbers. The sin mentioned in Christianity means treachery against the supreme deity. It is implied that sin is not tolerated in the world of God. Due to this, the first man, Adam, was driven out of Eden after betraying God, and afterwards, there came to be an infranchissable boundary between the world of God and the world of man. By way of comparison the faulty Degree Numbers, mentioned in Daesoon Jinrihoe, were produced naturally. In other words, the faulty Degree Number existed not only in the human world, but also in the world of divinities, and those two worlds not only interact but also affect each other. Therefore, it can be said that the two worlds of Christianity are worlds in which order and systems are completely different, and that the two worlds of Daesoon Jinrihoe are worlds that operate under the same order and systems. Both explain via this two-part division to emphasize one part as more important than the other. Christianity regards the world of God as the ultimate source and ultimate concern of the human world and emphasizes the absolute faith and worship of God is the highest value in life. But Daesoon Jinrihoe, on the other hand, argues that the human world determines the value of the divine world, and that the co-prosperity of man and his surroundings are the core values of the human era (The Era of Human Nobility). Therefore, the root cause of Christianity's theocentricity is that among the two worlds that are completely cut off from one another, they believe in God's world as the ultimate source and purpose of the human world. The root cause of Daesoon Jinrihoe's anthropocentrism is that among the two worlds that interact and influence each other, they believe the human world determines the meaning of the divine world.

Objective: Triplet-born lambs are less likely to survive to weaning than twin-born or single-born lambs. Appropriate ewe-lamb bonding behaviours and lamb vigour behaviours are necessary for survival of lambs. The aim of this experiment was to determine whether maternal nutrition during late pregnancy influenced behaviour of the ewe and her lambs soon after birth, and to determine whether mid-pregnancy body condition score (BCS) influenced any behavioural response. Methods: The experiments included ewes that were in BCS 2.0, 2.5, or 3.0 in mid-pregnancy and were fed either ad libitum or to pregnancy-maintenance requirements in late-pregnancy (day 115 until 136 in experiment one, and day 128 until 141 in experiment two). The time taken for lambs to stand, contact dam, suck from dam and follow dam was recorded three to 18 h after birth. The number of high- and low-pitched bleats emitted by the ewe and lambs was recorded, along with maternal behaviour score (MBS) of the ewe. Lambs in experiment two underwent a maternal-recognition test at 12 or 24 h. Results: There were significant effects of feeding treatment on bleating behaviour of ewes and lambs, but these were inconsistent among BCS groups and between experiments. Lamb vigour behaviours were not affected by feeding treatment. In experiment one, there was no effect of feeding treatment or BCS on MBS, but in experiment two, ewes in BCS3 in mid-pregnancy had greater MBS than ewes in BCS2 in mid-pregnancy (MBS 3.1/5 vs MBS 2.1/5; p<0.05). Conclusion: Given there were no repeatable effects on behaviour of ewes and lambs, ad libitum feeding rather than feeding for pregnancy-maintenance requirements cannot be used to improve behaviours soon after birth of triplet-bearing ewes in BCS 2-3 and their lambs in extensive pastoral conditions.

This study was to investigate the effect of flavonoid treatment on in vitro development of bovine somatic cell nuclear transfer (SCNT) embryos, and their pregnancy and delivery rate after embryo transfer into recipient. In experiment 1, to optimize the flavonoid concentration, parthenogenetic day 2 ($\geq$ 2-cell) embryos were cultured in 0 (control), 1, 10 and $20\;{\mu}M$ flavonoid for 6 days. In the results, in vitro development rate was the highest in $10\;{\mu}M$ flavonoid group (57.1%) among treatment groups (control, 49.5%; $1\;{\mu}M$, 54.2%; $20\;{\mu}M$, 37.5%), and numbers of total and ICM cells were significantly (p<0.05) higher in $10\;{\mu}M$ flavonoid group than other groups. We found that $10\;{\mu}M$ flavonoid treatment can significantly (p<0.05) decrease the apoptotic index and derive high expression of anti-oxidant, anti-apoptotic, cell growth and development marker genes such as Mn-SOD, Survivin, Bax inhibitor, Glut-5, In-tau, compared to control group. In experiment 2, to produce the cloned Jeju Black Cattle, beef quality index grade 1 bull somatic cells were transferred into enucleated bovine MII oocytes and reconstructed embryos were cultured in $10\;{\mu}M$ flavonoid added medium. When the in vitro produced day 7 or 8 SCNT blastocysts were transferred into a number of recipients, $10\;{\mu}M$ flavonoid treatment group presented higher pregnancy rate (10.2%, 6/59) than control group (5.9%, 2/34). Total three cloned Jeju Black calves were born. Also, two cloned calves in $10\;{\mu}M$ flavonoid group were born and both were all healthy at present, while the one cloned calf born in control group was dead one month after birth. In addition, when the result of short tandem repeat marker analysis of each cloned calf was investigated, microsatellite loci of 11 numbers matched genotype between donor cell and cloned calf tissue. These results demonstrated that the flavonoid addition in culture medium may have beneficial effects on in vitro and in vivo developmental capacity of SCNT embryos and pregnancy rate.

A combined technology of transvaginal ovum pick-up(OPU) system with in vitro-oocyte manipulation technique can be used for improving reproductive efficiency in the cattle. The objective of this study was to establish a newly-conceived breeding program using OPU in the pregnant cows. The OPU trial was performed in pregnant cows every 10 days from 40 through 90 days of artificial insemination (Al), and number of follicles in ovary, number of retrieved oocytes and embryo development following in vitro-fertilization, were evaluated. Reduced number of follicles in the ovaries of pregnant cows was firstly detected from 70 days after A' and a significant (P<0.05) decrease in the follicle number (5.4 follicles /donor) was found at 90 days than at 40, 50, 60 and 80 days after Al (8.0~9.2). A similar pattern was also observed in the number of oocytes retrieved by OPU apparatus during experimental period. When retrieved oocytes were matured and inseminated in vitro with frozen bull semen, development of the oocytes to the blastocyst stage was not significantly affected by the retrieval time. Four embryos (morula or blastocyst stage) derived from oocytes retrieved from pregnant cows were nonsurgically transferred to four recipient cows on day 7 of estrus cycle. For the first time in Korea, three of four transferred embryos developed to live calves with normal physiological parameters. In conclusion, an effective breeding program employing pregnant cow can be developed by use of OPU trial and in vitro culture techniques of oocytes ; OPU system could be repeated in pregnant cows with no risk of abortion and viable offsprings were borne after transfer to the recipients.

The interstitial cells of Cajal are the pacemakers in the gastrointestinal tract that modulate gastrointestinal motility. A case of a neonate with intestinal pseudo-obstruction caused by a decreased number of the interstitial cells of Cajal is presented. A premature male infant born at 32 weeks of gestation showed progressive abdominal distention beginning 3 days after initiation of enteral feeding at 15 days of life. No etiologic factors were identified on radiologic studies, a gastrographin enema, and an intestinal biopsy other than a markedly decreased number of the intestinal cells of Cajal. An ileostomy, followed by repair of the ileostomy was done, which resulted in but a limited improvement of the abdominal gas pattern. Respiratory distress, pancytopenia, and abdominal distention persisted, and the infant expired on 142 days of life.

This study was conducted to estimate the effect of the breed, sire-breeds, farrowing year, farrowing season and parity on number of born alive (NBA), number of weaning (NW) and survival rates of weaning (SRW) in swine. The data were obtained from 46,704 litters of the Landrace, Yorkshire, Duroc and Cross breed farrowed from 1996 to 2005 at 142 GP are registered in Korean Animal Improvement Association (KAIA). There was highly significant effect of breed, sire breed, farrowing year, farrowing season and parity on NBA, NW, SRW (p<0.01). The result of this study could be available to genetic improvement of reproductive traits as a basic reference in Korean pig industry. To achieve the more effective improvement of reproductive traits, additional research such as genetic parameter evaluation should be performed.

In the history of fashion, the category of knitted items was traditionally associated with ordinary clothing products like undergarments and socks. However, in a mere century Chanel has changed that idea by bringing into fashion consciousness items such as sports sweaters, jerseys, and suits, and so it has been necessary to upgrade this notion. As the needs of the times and new inventions have an inseparable relationship, knit fashion was also born with a close relationship with the zeitgeist of the time - the feminine movement, the rise of sports fashion and the world war - adapting itself up to the present time through continuous changes. Most brands are elevating knit from a mere decoration into a collection piece in a large number of collections every year. The number of brands that cannot exist without knit is increasing, such as Sonia Rykiel, Missoni, and so on. This essay is written with the purpose to study the birth, growth and future potential of knit items. The first stage concentrates on the age of knit's appearance (1910s-1930s). Contingent upon the collection of further data, this essay will be continued through the second stage (the 1960s - 1970s) and the third stage (after the 1980s).
