Weight change in the postpartum period is a dominant concern of new mothers recently. Postpartum weight retention has important public health implications as well, because retention of gestational weight can be a significant contributor to longterm obesity and associated health risks. As traditional medical practitioners have managed some problems from postpartum weight retention, use some terms translated in Korean like as postpartumedema, obesity. But those have been not given any discuss objective and with evidences for nomenclature. Now reports review normal postpartum weight loss patterns, as well as risk factors for weight retention, ancient literatures, so practitioners can assist their patients in achieving a healthy postpartum weight.

Just after hatching the embryo has a yolk sac and straighted digestive tract. Just after parturition in 5.0mm TL the mouth and anus were opened. In the larval stage of 5.2mm TL, digestive tract could be divided into pharynx, esophagus, stomach, pyloric caeca and intestine of the early differentiated state. The esophagus of larvae in 5.3mm TL has a PAS positive mucous cell. From over 5.7mm TL, PAS positive goblet cell recognized in the intestine. PAS positive absorptive cell began to appear in the intestine from 5.9mm TL. Yolky materials were absorbed completely in 6.0mm TL. In the larvae of B.5mm TL, gastric glands were observed in the mucosa, but the surface epithelium did not have PAS positive granules. From over 9.0mm TL, the histological structure of esophagus showed similar to adult. In the juvenile stage from 13.0mm to 15.0mm TL, histological structure of the stomach, pyloric caeca and intestine showed similar to adult. From the ultrastructural and histochemical study, it is concluded that the functional digestive tract is present in the juvenile stage from 18.0mm to 20.0mm TL.

Abstract Social pathologic phenomenon such as low fertility, nuclear family and one person households seems to be on the rise as Korea moves towards being an aging society. We think many trouble is expected to be exit as aging society progresses, but there were few studies about an aging society, especially funeral culture. Appearance of the aging society in Korea similarly follows the course of Japan. So we studied about similar funeral culture of aging society in Japan and prepared for the funeral culture in Korea. This study will suggest a gaze on realistic objective point of view, through the way to illustrate exactly the concept of "funeral for family (家族葬)" among Japanese funeral culture(Syukacheu(終活), Chyokusou(直葬) and funeral for family(家族葬)) and will be expected to be an important guide for leading the funeral culture in Korea occur due to aging in future. And this study will give a chance to ruminate on our's funeral attitude about the deceased's dignity.

This study analyzed the unit of child rearing in four Household textbooks approved by the Department of Education during the 1920s-30s. These Household textbooks is contained a unit related to child rearing among Household textbooks approved by the Department of Education at that time. The results of the analysis are summarized as follows. First, the structure of the child rearing unit in the Household textbooks were largely composed of 'part, chapter and section' and this structure and contents were similar among all the textbooks. Second. in general, the four textbooks spared a large space for 'childcare,' nursing' and 'new-born babies and infants,' suggesting the importance of these contents. Third, cautions for pregnant women were taught to call attention not only of pregnant women but also of their families to importance of pregnancy. Fourth, the child rearing unit contained many illustrations and pictures and some pictures were shared among the textbooks. Firth, in acquiring medical knowledge related to diseases, the textbooks demanded child-rearing mothers to 'observe' and 'scrutinize' any symptoms appearing in the child. These contents were connected with commercial products but far distant from the realities. The detailed method of 'nursing' also required a lot of time and accuracy impractical in real life.

The worm development and egg laying pattern of Echinostoma hortense (Trematoda; Echinosto-matidae) were studied in albino rats and the brief clinical course was observed in human volunteers. A total of 21 rats were infected with 20~69 metacercariae each and two humans were with 7 and 27 metacercariae, which were collected from the loaches. For recovery of worms, the rats were sacrificed at irregular intervals from the 6th to 150th day after infection and the human volunteers were treated with praziquantel and purged with magnesium salt on the 26~27th day. The stools of the rats and humans were examined for the eggs. The results were as follows: 1. The worm recovery rate from the rats was not affected by the increase of infection time but varied individually; 9.1~50.0% (31.1 % in average). From humans, 14.3% and 37.0% (32.4% in average) of challenged were recovered. 2. In the rats, it was revealed that the worms rapidly grew for the first 14 days to become 7.59mm in average length and 1.17mm in average width but the growth became much slower thereafter until the 150th day; 7.95mm in length on the 21 th day, 9.04mm on the 28th day, 10.21mm on the 49th day and 12. 62mm on the 150th day. During the early stage of infection, the growth of genital organs (male or female) was expressed as sigmoid curves whereas non-genital organs (such as suckers) was simply as straight lines. 3. The prepatent period of this fluke was 10~12 days in the rats and 16~17 days in men. After the start of oviposition, the egg production by the worms remarkably increased, reached maximum on the 32~33th day, followed by decrease thereafter. The maximum value of E.P.G./worm was 390. 4. The major subjective symptoms in human volunteers were abdominal pain and diarrhea during the early stage of infection. The results show that human is as susceptible as the rats to E. hortense infection and the amount of egg production in the rats is greatly affected by the age of worms.

Brain abscesses in neonates are extremely rare and usually occur in patients with certain risk factors. A 1-month-old boy presented at the hospital with fever and irritability. As a result of preterm delivery and low birth weight, he had a history of admission to the neonatal intensive care unit. Neuroimaging revealed a large, space-occupying lesion in both frontal lobes, which was suspected to be an abscess with the midline shifting to the right. With a single aspiration and abscess drainage along with concurrent prolonged parenteral antibiotic therapy, the patient showed an excellent treatment outcome with normal development. The focus will be placed on minimally invasive surgical management as well as positive outcomes.

The reproductive cycle of ovoviviparous melania snail, Semisulcospira libeytina libertina was studied in the valley near Naewon Temple in Yangsan, Korea. Water temperature (WT) of the habitat ranged from 1.3$^{\circ}C$ to 22.5$^{\circ}C$ The meat weight rate (MWR) reached the maximum with the beginning of WT increase in March and the minimum in August. Monthly changes in average oocyte diameter showed the maximum (249.6$\pm$2.6 ${\mu}{\textrm}{m}$) in July and the minimum (134.3$\pm$2.8 ${\mu}{\textrm}{m}$) in December S. libertina libertina seemed to be a year-round breeder except for mid-summer and mid-winter. Two main reproductive cycle of the species could be divided into five successive stages: multiplicative (March, October), growing (April and May, November), mature (June and July, December), ovulation (August, January), parturition (September and October, March to May) and resting (September, February) stages in female and multiplicative (March, October), growing (April, November), mature (March to June, December), copulatory (July and August, January), resting (September, February) stages in male.

Scenario population projection reflects the high probability of future realization and ease of statistical interpretation. Statistics Korea (2019) also presents the results of 30 combinations, including special scenarios, as official statistics. However, deterministic population projections provide limited information about future uncertainties with several limitations that are not probabilistic. The deterministic population projections are scenario-based estimates and show a perfect autocorrelation of three factors (birth, death, movement) of population variation over time. Therefore, international organizations UN, the Max Planck Population Research Institute (MPIDR) of Germany and the Vienna Population Research Institute (VID) of Austria have suggested stochastic based population estimates. In addition, some National Statistics Offices have also adopted this method to provide information along with the scenario results. This paper calculates the demographics of Korea based on a probabilistic or stochastic basis and then draws the pros and cons and show implications of the scenario (deterministic) population projections.

Objectives : The purpose of this study is to evaluate the effect of the heating-conduction acupuncture therapy on the postpartum low back pain patients. Methods : Heating-conduction acupuncture therapy was administered three and four times on three postpartum low back pain patients. The improvement of clinical symptoms was evaluated by SF-MPQ(short form-McGill pain questionnarie), VAS(visual analogue scale) and ODI(oswestry disability index). Results : After treatment, each three patients' SF-MPQ, VAS and ODI score reduced respectively. Conclusions : Heating-conduction acupuncture therapy for postpartum low back pain patients was effective. Although this cases presented valuable result, further research is encouraged to confirm the effectiveness of this treatment.
