A ten-year-old, male cat presented with recent loss of body weight, depression, vomiting, anorexia, polydipsia, and polyuria. General physical findings included depression, weakness, severe dehydration and a strong acetone odor on the breath. A complete blood count and serum biochemical profiles were leukocytosis, hyperglycemia (286 mg/dl), hypokalemia (2.6 mEq/L), hyponatremia, and high serum fructosamine (600 $\mu$mol/L). In blood gas analysis the cat had acidosis (pH 7.127, p$CO_2$26.7 mmHg). In urinalysis glycosuria and ketouria were appeared. On the basis of clinical signs, serum chemistry, blood gas analysis and urinalysis, diabetic ketoacidosis was diagnosed. Treatment included subcutaneous administration of protamine zinc insulin (0.75 U/head) and intravenous administration of 0.9% saline. Potassium phosphate and sodium bicarbonate was added to the fluids. Serum fructosamine for assessment of glycemic control was measured on occasion calls. On day 296, the patient improved clinically and did not experience any problems resulting from diabetic ketoacidosis.

This study explores whether Russian, known to have a process of syllable-final devoicing, reveals differences in vowel duration as a function of the underlying voicing of the coda stop. This paper also examines whether non-native speakers of Russian and English learn typical L2 values in vowel duration. The results indicate that vowels in Russian have a slightly longer mean duration before a voiced stop than before a voiceless stop (a mean difference of 9.52 ms), but in most cases the differences did not exhibit statistical significance. In English the mean difference was 60.05 ms, and the differences were in most cases statistically significant. All native Russian speakers of English produced larger absolute differences in vowel duration for English than for Russian, and all native English speakers of Russian produced smaller absolute differences for Russian than for English. More experienced learners seemed to achieve more native-like values of vowel duration than less experienced learners did, suggesting that learning occurs gradually as the learners gain more experience with the L2.

In DC micro-grid system energy storage systems (ESS) are responsible for storing energy and balancing power. Also, control target of the bidirectional DC-DC converter(BDC) for ESS should be changed depending on the operating mode. During the grid connected mode, the BDC controls the battery current or voltage. When a grid fault occurs, the BDC should change the control target to regulate the DC-bus. The BDC with conventional control method may experience large transient state during the mode change. This paper proposes a control method of BDC for ESS. The proposed control method is able to provide autonomous and seamless mode transfer by a variable current limiter. To validate the proposed concept, simulation results using PSIM and experimental results from a 2kW prototype are provided.

The measurement of $17{\alpha}$-hydroxyprogesterone ($17{\alpha}$-OHP) in a dried blood spot on filter paper is an important for screening of congenital adrenal hyperplasia (CAH). Since high levels of $17{\alpha}$-OHP are frequently observed in premature infants without congenital adrenal hyperplasia, we evaluated cuts-off based on birth weight and performed validation. Birth weight and $17{\alpha}$-OHP concentration data of 292,204 newborn screening subjects in Greencross labopratories were analyzed. The cut-off values based on birth weight were newly evaluated and validated with the original data. The mean $17{\alpha}$-OHP concentration were 7.25 ng/mL in very low birth weight (VLBW) group, 4.02 ng/mL in low birth weight (LBW) group, 2.53 g/mL in normal birth weight (NBW) group, and 2.24 ng/mL in heavy birth weight (HBW) group. The cut-offs for CAH were decided as follows: 21.12 ng/mL for VLBW and LBW groups and 11.14 ng/mL for NBW and HBW groups. When applied new cut-offs for original data, positive rates in VLBW and LBW groups were decreased and positive rates in NBW and HBW groups were increased. The cut-offs based on birth weight should be used in the screening for CAH. We believe that our new cut-off reduce the false positive rate and false negative rate and our experience for cut-off set up and validation will be helpful for other laboratories doing newborn screening test.

Tunneling is one of the challenging tasks in civil engineering because it involves a variety of decision making and engineering judgment based on knowledge and experience. One of the challenges is to construct tunnels in risky areas under shallow overburden. In order to prevent the collapse of ceilings and walls of a large tunnels, in such conditions, either a sequential excavation method (SEM) or ground reinforcing method, or a combination of both, can be utilized. This research deals with the numerical modeling of L-profiles and pipe fore-poling pre-support systems in the adit tunnel in northwestern Iran. The first part of the adit tunnel has been drilled in alluvial material with very weak geotechnical parameters. Despite applying an SEM in constructing this tunnel, analyzing the results of numerical modeling done using FLAC3D, as well as observations during drilling, indicate the tunnel instability. To improve operational safety and to prevent collapse, pre-support systems, including pipe fore-poling and L-profiles were designed and implemented. The results of the numerical modeling coupled with monitoring during operation, as well as the results of instrumentation, indicate the efficacy of both these methods in tunnel collapse prevention. Moreover, the results of modeling using FLAC3D and SECTION BUILDER suggest a double angle with equal legs ($2L100{\times}100{\times}10mm$) in both box profile and tee array as an alternative section to pipe fore-poling system while neither $L80{\times}80{\times}8mm$ nor $2L80{\times}80{\times}8mm$ can sustain the axial and shear stresses exerted on pipe fore-poling system.

This is a descriptive study to understand the preventive stage for STDs to provide a basis for sex education for college students. The colleges were selected by quota sampling in five representative cities in Korea. but the 1,691 college students were selected by convenient sampling in the cities nationwide, and the data were collected by self-reporting using a questionnaire consisting of 33 items. The results were as follows : 1. Their mean ages were 21.8 for female and 23.3 for male students, 2.78.0% of the males md 46.5% of the females permitted premarital sex, 57.1% of male and 10.3% of female college students had experienced sexual intercourse, 7. l% of males and 2.4% of females had experienced pregnancy, 10.3% of males and 3.4% of females had been infected with STDs, 72.1% of male and 13.8% of female didn't use condoms at the time of infection. 3. Most of the factors related to STDs infection, such as drinking, smoking, frequency of sexual intercourse. pregnancy, knowledge of STDs, the score of STDs prevention were statistically higher in the male student group than in the female group. 4. The students' mean score of knowledge about STDs was similar between the male group(7.80) and the female group(7.84) with a possible score range from 0-18. 5. Only fifteen percent of male and 9.6% of female students expressed that they will do something to prevent STD. 6. The group having the experience of sexual intercourse(t=3.924, P=.048) and the group of having experience of contracting STDs(t=16.638, P=.000) had shown statistically higher STDs prevention score than the group not having that kind of experience. but the group having experience with pregnancy didn't show any difference from. the group not having experience with pregnancy. Considering that 57.1% of males and 10.3% of females had sexual intercourse experience, 78% of male and 46.5% of female permitted premarital sex, 10.3% of male and 3.4% of female had been infected with STDs. It could be concluded that the college students were ignorant about the prevention of STDs and had unrealistic stage of the STDs prevention. Therefore, enforcement of education for the prevention of STDs including the dynamics of the sexual intercourse and STDs infection is needed.
