Objective: An experiment was conducted to evaluate the effect of different levels of crude protein (CP) and two rearing systems (cage and floor), on blood parameters and digestive and reproductive organ development of brown laying hens. Methods: A total of 400 Hisex Brown laying hens between 30 and 45 weeks of age were distributed in a completely randomized design and a 2×4 factorial arrangement, with main effects including two rearing systems (cage and floor) and levels of CP (140, 150, 160, and 180 g/kg), in a total of eight treatments and five replicates of 10 birds each with initial body weight of 1,877 g (laying hen in cage) and 1,866 g (laying hens in floor). The parameters evaluated were plasma total protein, albumin, uric acid, total cholesterol, relative weights of oviduct, abdominal fat, liver, gizzard, crest and dewlap, length of small intestine and oviduct. Results: The blood parameters were similar in birds reared in cage and floor systems. The birds reared on the floor showed greater small intestine and oviduct weight (%) and lower liver and pancreas weight (%). A significant interaction was observed between factors for the relative gizzard, crest and dewlap weight, serum protein, uric acid, and total cholesterol (p<0.05). The diets with 140 g/kg CP resulted in lower serum protein and lower cholesterol in birds reared in floor system, while birds reared in cage system showed no effect of CP on both parameters. Birds reared in cage and fed with 140 and 150 g/kg CP presented lower uric acid. The group of birds reared in floor system fed 180 g/kg had greater uric acid. Conclusion: The dietary protein level can be reduced up to 140 g/kg for Hisex Brown hens (30 to 45 weeks of age) without an important effect on metabolic profile and organ development in both rearing systems.

When it is necessary to wear masks for long periods, such as during the current COVID-19 pandemic, the essential function of masks to prevent contamination (or transmission to others) as well as comfortableness are important. For this study, we used three-dimensional (3D) facial measurements of adult women to compile basic face shape data for designing comfortable and effective masks. This study analyzed the 3D facial data of 127 subjects in their 20s to 30s of the 6th Size Korea. Factor analysis of the survey data produced seven factors that formed the composition of adult female faces. These factors combined to produce three facial types: square (long face and a large lower middle face), oval (smallest central and lower body in the middle), and triangle (short face with a small central and lower large nose). These types reflect that the facial types of adult women show the differences in the nose angle, nose length, bitragion-subnasal arc, bitragion-menton arc. Therefore, properly fitting masks for fine dust particle filtration require 3D customization of a mask's breathing apparatus to fit differently shaped central and lower face parts that interfere with mask fit.

The effects of supplementation with mixed fodder or concentrate were investigated on the performance of a) growth of male lambs and kids grazing extensively under oil palm trees and b) reproduction of ewes and goats stall-fed with native herbage. Supplemented kids and lambs had higher average daily weight gain than controls but the effect was only significant for those which received concentrate (p < 0.05). Final body weight was only significantly different from controls for lambs supplemented with concentrate (p < 0.05). The ages at puberty, first mating, first conception and first kidding of supplemented goats were about 110 days earlier than those for controls (p < 0.05 or better). Supplemented goats had first mating and conceived at lower body weights (p < 0.01) than those in control groups. Different feeding regimes had no effects (p > 0.05) on the reproductive performance of ewes apart from highest body weight of first lambing in animals supplemented with concentrate (p < 0.05). Native herbage available under oil palm trees of 5 years old was sufficient for growth and reproduction of sheep and goats. Concentrate was better than mixed fodder as supplement for enhancing the reproductive performance of goats but both appeared to have limited effects on the performance of reproduction in ewes and growth in male kids.

Recently the demand for natural gas as clean and safe energy due to concerns about global warming and interests in green ship is increasing. The dual fuel(DF) engine, one of environmentally friendly engines, is preferred for general merchant ships and power plants as well as LNG carriers. This is for the reasons of having higher efficiency and lower nitrogen and sulfur oxides emissions by operating on LNG fuel with a small amount of light fuel oil. In this study, the engine body vibration characteristics of 12V50DF in a generator set with engine-resilient-mounted, generator-rigid-mounted and flexible-coupling configuration are investigated through theoretical analysis and comprehensive vibration measurement. This analysis showed the dynamic behavior of engine excitation forces and seismic waves. And the suitable countermeasures for reducing vibration and safe operation are proposed.

This study was performed to identify the effect of Backchulsan and Backpeundu, on the muco-substances of the goblet cells in the small and large intestines of the mouse. After injected castor oil into oral cavity, the experimental animals were administrated with 5.952mg per 30g body weight of Backchulsan, with 0.519mg per 30g body weight of Backpeundu. The specimens used in this study were obtained from the small and large intestines of the mouse. All specimens were stained with periodic acid-Schiff reaction, alcian blue pH 2.5 and alcian blue pH 1.0 procedures. The results were as follows : 1. The most remarkable decrease of neutral and acid mucosubstance was observed in the control group 1 and 6 hours after castor oil administration. 2. Increase of neutral and mucosubstance was observed in Backchulsan administration group 3 hours in comparision with that of control group administrated of castor oil, especially of the upper and lower villi regions. 3. Increase of neutral and acid mucosubstance was observed in Backpeundu administration group 6 hours in comparision with that of control group administration of castor oil. 4. The most remarkable increase of neutral and acid mucosubstance was observed in Backchulsan administration group after 3 hours in comparision with that of Backpeundu administration group.

This study was conducted to optimize the efficiency of cloning and to produce cloned mice. The majority of cloned mammals derived by nuclear transfer (NT) die during gestation and have enlarged and dysfunctional placentas. In this study, the optimized conditions were established to produce clone mice. The parthenogenetic oocytes were activated after 6 h regardless of cytochalasin B (CB) concentration. CB treatment ($2{\mu}g/ml$) was found second polar body. Lower concentration of CB was decreased the activation rate, but the second polar body was the best highly increased during 6 h incubation. The small fragments were exhibited in the $5{\mu}g/ml$ treatment of CB, but it was not found in lower concentration groups (> $2.5{\mu}g/ml$). To examine effects of $SrCl_2$ on the adult cumulus cells, somatic cell NT oocytes were exposed during 0.5, 1 and 6 hrs. The second polar body was significantly greater in 0.5 h exposure group (6.6%) than 1, 6 hrs. Developmental rate from 2-cell to 4-cell was the lowest in 7.5 mM Strontium chloride ($SrCl_2$) groups (84.1% and 64.3%) than 5, 10 m $MSrCl_2$. The implantation rate was not significantly difference among 5, 7.5 and 10 m $MSrCl_2$ group. Three live fetuses were produced by SCNT. SCNT placentas were remarkably heavier than IVF group (8 fetuses) (0.34, 0.34, 0.33 vs 0.14 g) compared with the placenta weight of IVF and SCNT clones.

A nine-month-old intact female Maltese dog (body weight: 1.5 kg) presented with frequent syncopal episodes (1-2/day), exercise intolerance, and dyspnea. Cardiomegaly with marked dilation of right and left atria along with ascites was indicated on radiography. Tricuspid regurgitant jets (4.36 m/s), pulmonary regurgitant jets (3.4 m/s), left-to-right shunting flow at the ductus arteriosus, and an atrial septal defect were observed on echocardiography. A bubble study with agitated saline found right-to-left shunting at the interatrial septum. Based on diagnostic studies, the dog was diagnosed with right-to-left atrial septum defect (ASD) compounded with patent ductus arteriosus (PDA). The treatment was directed to reduce the pulmonary hypertension, improve cardiac performance, and lower fluid retention. Despite medical treatment for 2 months, the dog died of sudden cardiac arrest. Herein, we describe a very rare case of right-to-left ASD compounded with PDA.

Objective: The aim of the study was to investigate pregnancy, obstetric, and neonatal outcomes in women with small (<4 cm) unilateral endometriomas. Methods: This retrospective study included 177 patients: 91 patients with small endometriomas and 86 controls with unexplained or tubal factor infertility who were treated at the Süleymaniye Gynecology and Maternity Training and Research Hospital Infertility Unit between January 2010 and July 2015. The groups were matched with regards to demographic characteristics such as age, body mass index, and infertility duration. All of the women in this study conceived via intracytoplasmic sperm injection. We compared pregnancy, obstetric, and neonatal outcomes between these groups. Results: Women with endometriomas had a higher biochemical pregnancy rate, but lower clinical pregnancy and live birth rates than women with unexplained and tubal factor infertility (p<0.05 for all). However no significant differences were found in terms of obstetric and neonatal complications between the two groups (p>0.05 for all). Conclusion: In this study, we found that women with endometriomas less than 4 cm were more prone to early pregnancy complications. We also showed that this group did not have any increased risks of late pregnancy, obstetric, and neonatal complications.

The purpose of this study is firstly to survey the social and cultural background of 20th century and women's status, and to identify what the ideal body is like and what the elements of outer garment and underwear are and the techniques to incarnate the ideal beauty. Various papers are referenced for theoretical study and the elements and techniques of underwear are analyzed based on photographical materials. This paper concludes as follows. In 1910's, ideal beauty has changed to H-style. In other words, the outer garment has confined the lower part of the body with plain H-type Hobble silhouette to express plump bust, somewhat slim waist, and small hips, As the underwears, cylindrical corsets which fasten from under the bust down to lap, brassiere which are helpful for plump bust, and artificial busts were worn. In 1920's, outer garment were Straight box silhouette style which were cut as tubular without dart, and the underwears were corselets which have been tubular from the bust to hip and the tubular chemi-knickers. The former corsets which had been hard-boned and been fastened with strings have been replaced by the hook closure due to the development of elastic joining method. In 1930's, women pursued perfect body showing the line of bust, waist, and hip. In order to express elegant beauty of female of Slim and long silhouette, Doter and underwear have been cut with bias and gore, and soft and flexible materials were flowed along the body. World war II in 1940's has made the women as social. Ideal beauty has changed to Short straight box silhouette which no more shows body line. Outer and underwears were simple and Practical style. In 1950's, ideal beauty was well-matured, elegant Women which were represented by round shoulder, conical breast, tiny waist and round hip. Outer garment showed Hourglass silhouette representing the body-tight suits with round shoulder pad and the wide flare skirts. As the underwears, conical brassiere by top circular stitch were preferred for plump and bulged bust and tight corsets for tiny waist and magnificent petticoats were worn.

In this paper, we propose a new Intra-body communication system for bio-sensor which is one of applications in PAN(Personal Area Network) using body channel. The communication systems for bio-sensor network usually transmits a lot of data acquired in sensor to the receiver in wrist or waist. So we deign the intra-body modem with high data rate, low power, and small size which are achieved by baseband communication techniques. It is noted that the baseband transmission does not requires any analog IF and RF frontends, and can be operated in lower frequency than bandpass transmission. The proposed modem operates at 10MHz band according to the characteristics of intra-body channel, and shows the capability of 5Mbps data rate at distance of 20cm, with $BER=10^{-5}$. In addition, we implement the modem within $2{\times}2cm$ area.
