Large Language Models (LLMs) are becoming the major trend in the natural language processing field. These models were built based on research data, but information such as types, limitations, and risks of using research data are unknown. This research would present how to analyze and evaluate the LLMs that were built with research data: LLaMA or LLaMA base models such as Alpaca of Stanford, Vicuna of the large model systems organization, and ChatGPT from OpenAI from the perspective of research data. This quality evaluation focuses on the validity, functionality, and reliability of Data Quality Management (DQM). Furthermore, we adopted the Holistic Evaluation of Language Models (HELM) to understand its evaluation criteria and then discussed its limitations. This study presents quality evaluation criteria for LLMs using research data and future development directions.

다중처리기 상에서 실시간 태스크 스케줄링에 대한 연구가 현재 많이 수행되고 있지만, 주로 Pfair(P-fairness)와 EDF(Earliest Deadline First) 알고리즘에 대한 연구이다. Pfair는 이론적인 연구에 초점을 두고 있으며, EDF는 처리기들을 효율적으로 이용하지 못하는 문제점을 가지고 있다. 본 논문에서는 다중처리기 상의 주기적인 실시간 태스크 집합을 대상으로, LLA(Least Laxity Algorithm) 알고리즘이 높은 스케줄링 가능성(schedulability)을 가짐을 먼저 보인다. 다음으로 기존 알고리즘들의 문제점을 보완하기 위해 EDF와 LLA를 결합한 ED/LL(Earliest Deadline/Least Laxity)이라는 알고리즘을 제시한다. ED/LL은 LLA보다 문맥교환 횟수는 적고 EDF보다 스케줄링 가능성이 높으며, 구현 오버헤드도 크지 않다.

Objective : Obesity is associated with degenerative arthropathy giving stress on joints. It also amplifies loads of weight bearing joints by changing the gravity line of the body. Our aim is to investigate the correlation between obesity and lumbar lordosis in obese pre-menopausal Korean females. The hypothesis was tested that there is a correlation between obesity and lumbar lordosis. Methods : A cross-sectional evaluation of 44 Females (baseline age 30.77 ± 6.46) with BMI 31.53 ± 3.82 (kg/㎡) was done. Body composition was measured using bio-impedance analysis (BIA), and anthropometry was done by the same observer. A lateral whole spine X-ray was taken in standing position to measure the lumbar lordotic angle (LLA), Ferguson angle (FA) and lumbar gravity line (LGL). A Pearson correlation was used to measure the correlation between obesity and lumbar lordosis (SPSS 10.0 for windows). Results : Body mass index (BMI kg/㎡) had a negative relationship with LLA((equation omitted)=-0.469), FA((equation omitted) =-0.347) and LGL((equation omitted)=-0.389). Body fat rate had a negative relationship with LLA only(γ=-0.385). Waist circumference had a negative relationship with LLA((equation omitted)=-0.345) and LGL((equation omitted)=-0.346). WH ratio had no relationship with lumbar lordosis. Conclusion : These data show that obesity is related to mechanical structures, such as lumbar lordosis. BMI was the most useful index, which reflects a change of mechanical structure of lumbar, more than other variables in this study.

For real-time systems, multiprocessor support is indispensable to handle the large number of requests. Existing real-time on-line scheduling algorithms such as Earliest Deadline First Algorithm (EDF) and Least Laxity Algorithm (LLA) may not be suitable for scheduling real-time tasks in multiprocessor systems. Although EDF has low context switching overhead, it suffers from "multiple processor anomalies." LLA has been shown as suboptimal, but has the potential for higher context switching overhead. Earliest Deadline Zero Laxity (EDZL) solved somewhat the problems of those algorithms, however is suboptimal for only two processors. Another algorithm EDA2 shows very good performance in overload phase, however, is not suboptimal for muitiprocessors. We propose two on-line scheduling algorithms, Earliest Deadline/Least Laxity (ED/LL) and ED2/LL. ED/LL is suboptimal for multiprocessors, and has low context switching overhead and low deadline miss rate in normal load phase. However, ED/LL is ineffective when the system is overloaded. To solve this problem, ED2/LL uses ED/LL or EDZL in normal load phase and uses EDA2 in overload phase. Experimental results show that ED2/LL achieves good performance in overload phase as wet] as in normal load phase.oad phase.

Preset study was carried out to evaluate characteristics of lactic acid producing bacteria(LAB) in hen's cecum as probiotics value. Distribution of LAB in intestinal tracts was investigated using 5∼25 weeks - old hens. So, 12 strains to LAB with different morphology were isolated purely. Acid tolerance of LAB tested at pH 1, 2, 3, and 4, and bile resistant also tested at 0, 0.3% and 0.5% bile salt concentration. Growth pattern of LAB observed to 60h. All strains of cecal LAB couldn't survive at pH 1, and decreased linearly survival colony after incubation at pH 2 although some strains could survive for 2h. Most of LAB maintained constant number at pH 3 and 4. The bacterial action could increase linearly at 0% bile salt concentration in all of tested strains. However, only one strain could multiply at 0.3% bile salt, others were influenced by bile salt. That tendency was similar at 0.5% bile salt. Growth was peaked at 12 to 18 h after innoculation. After peak, the decreasing pattern of colony was different to strains which some strains decreased rapidly or maintained for long time. The LAB of hen's cecum was similar to intolerance acidity, but different to resistant to bile salt and growth pattern by strain. So, we choose three strains which have probiocs value, and identified as Lactobacillus amylovorus LLA7, Lactobacillus crispatus LLA9 and Lactobacillus vaginalis LLA11.

Objectives: The purpose of this study was to compare the difference of Lumbar Lordosis Angle(LLA) between patients with Low Back Pain(LBP) and control groups. Methods: Questionnaires were completed by 40 adult LBP patients seeking physical therapy services and by 40 controls at the Department of Physical Therapy. Saejong Neurosurgical Clinic in Taegu city from October 1999 to March 2000. LLA was measured on lateral x-ray films in a standing position. The angle between a line parallel to the top of the first Lumbar(L1) and the top of the fifth Lumbar(L5) was defined LLA. Results: LLA of $29.88^{\circ}$ for LBP patients was a statistically significant decrease from that of $35.31^{\circ}$ for controls in the difference of lumbar lordosis(p<0.01). There were statistically significant differences between senders in patient groups. Females$(32.32^{\circ})$ had significantly greater angles than males$(27.32^{\circ})$(p<0.05), while $36.63^{\curc}$ for female was also greater than $34.12^{\circ}$ for male in the controls. No significant difference was found between age. In patient groups, $27.95^{\circ}$ for below age 40 was a smaller than $32.32^{\circ}$ for above, however, $35.82^{\circ}$ for below age 40 was a little greater than $34.27^{\circ}$ for above in controls. Patients in a sitting posture had greater LLA$(31.35^{\circ}$ than those standing$(28.93^{\circ})$, however values for controls were similar to each other. Conclusion: Results from this study indicate that distinct differences exist among patients and controls and gender, whereas little difference exists in age and working posture.

ABA triblock copolymers of L-lactide and trimethylene carbonate with several different compositions were prepared by sequential ring-opening polymerization in the presence of diethylene glycol. Also chain-extension reactions of the resulting copolymers were carried out using hexamethylene diisocyanate to produce relatively high molecular weight polymers, which could be cast into elastomeric tough films. The polymers with certain L-lactide contents were partially crystalline, exhibiting two-phase morphology. The polymer films showed reversible elastic behavior under tensile tension, providing a novel thermoplastic elastomer possessing desirable properties such as biodegradability and good mechanical properties.

This paper proposes a neural network algorithm for real-time multiprocessor scheduling problem. The proposed algorithm is developed base on Hopfield neural network for a benefit of parallel processing, in order to finish a requested task within a deadline time. To compare the performance of the proposed algorithm, we used EDA and LLA algorithm that has studied real-time multiprocessor scheduling before. The proposed algorithm is implemented hardware using VHDL.
