Abstract

We introduce HyperCLOVA X, a family of large language models (LLMs) tailored to the Korean language and culture, along with competitive capabilities in English, math, and coding. HyperCLOVA X was trained on a balanced mix of Korean, English, and code data, followed by instruction-tuning with high-quality human-annotated datasets while abiding by strict safety guidelines reflecting our commitment to responsible AI. The model is evaluated across various benchmarks, including comprehensive reasoning, knowledge, commonsense, factuality, coding, math, chatting, instruction-following, and harmlessness, in both Korean and English. HyperCLOVA X exhibits strong reasoning capabilities in Korean backed by a deep understanding of the language and cultural nuances. Further analysis of the inherent bilingual nature and its extension to multilingualism highlights the model's cross-lingual proficiency and strong generalization ability to untargeted languages, including machine translation between several language pairs and cross-lingual inference tasks. We believe that HyperCLOVA X can provide helpful guidance for regions or countries in developing their sovereign LLMs., Comment: 44 pages; updated authors list and fixed author names

Abstract

Sample treatment procedure, and the experimental parameters that need to be considered in size analysis of diesel soot particles using field-flow fractionation (FFF), are discussed. A probe-type sonication of 10 min in water containing 0.05% of Triton X-100 provides well-dispersed suspension of the soot particles. Sample treatment is found to be important for reduction in particle-particle interaction and, thus, for preparation of well-dispersed soot suspension. FFF elution profile of untreated suspension has a long tailing that does not return to the baseline until the external field is removed. The scanning electron micrographs show that the untreated suspension contains aggregated particles. Extraction of chemicals is also found to be important for preparation of welldispersed suspension. The suspensions prepared without the extraction step, have broader and larger size distributions than those prepared with the extraction step, due to the presence of soluble organic fractions (SOF) that cause particle-aggregation. FFF provides an excellent repeatability in size analysis of soot particles. The standard deviation of the mean diameter measured by FlFFF was 3.6%. Both Flow FFF (FlFFF) and sedimentation FFF (SdFFF) are tested for size analysis of soot particles. SdFFF provides higher size-selectivity than FlFFF and is less problematic in terms of the particle-channel interaction. Unlike in SdFFF, FlFFF analysis does not require the density information and, thus, the fractogram can be directly transformed to the size distribution. But FlFFF provides lower size-selectivity and has narrower dynamic range than SdFFF. [ABSTRACT FROM AUTHOR]

33. HIGH PERFORMANCE LIQUID CHROMATOGRAPHIC SEPARATION AND DETERMINATION OF CIPROFLOXACIN AND ITS METABOLITES IN URINE.

Abstract

An improved HPLC procedure for separating ciprofloxacin and its four metabolites, M1, M2, M3, M4 in urine, was developed. The procedure used is reversed phase chromatography, the stationary phase being the C18-column, followed by quantification using a UV detector. The mobile phase is a mixture of isopropanol, acetonitrile, tetrabutylammonium bromide (TBABr), heptanesulfonic acid (HSA), and 0.05% triethylamine, (adjusted to pH=3.0 with phosphoric acid.) In the process of determining the optimum separation condition, the effect of each ion-pairing reagent on the retention of all analytes was investigated and explained as well. This method involves an off-line solid phase extraction, using C18 Sep-Pak cartridges for ciprofloxacin and its metabolites in urine. The desorption condition is investigated by using different kinds of organic solvents, or a mixture of organic solvents and phosphate buffer, adjusted to different values of pH. At the optimum desorption condition, all analytes show a recovery rate over 90%. Based on this optimum condition, this method was applied to pharmacokinetic study of solutes in urine sample.
