초거대 언어모델은 과연 수수께끼 문제에 재치있는 답변을 할 수 있을까? 최근 초거대 언어모델(Large language model, LLM)은 강력한 성능 및 유저 만족도를 보이며 세계의 이목을 집중시키고 있다. 여러 태스크들에 대한 정량 평가를 넘어서 최근에는 LLM의 창의력 및 고도화된 언어능력을 평가하는 연구들이 등장하고 있다. 본 논문에서는 이러한 연구 흐름에 따라 LLM의 재치에 관해 고찰해본다. 이때 재치를 평가하기 위한 태스크로 이를 요구하는 말놀이인 수수께끼를 활용한다. 본 논문은 LLM이 수수께끼를 잘 수행하는지를 모델 추론을 통해 평가하며, 모델 추론 시 활용되는 프롬프트들의 성격에 따른 성능 변화를 관찰한다. 또한 수수께끼의 종류에 따른 모델의 능력을 비교 분석하며 LLM의 추론 결과에 대한 오류 분석을 수행한다. 본 논문은 실험을 통해 GPT-4가 가장 높은 성능을 보이며, 설명글이나 데이터 예시를 추가할 시 성능을 한층 더 향상시킬 수 있음을 확인한다. 또한 단어 기반보다는 특성 기반의 수수께끼에 더욱 강력한 성능을 보이며, 오류 유형 분석을 통해 LLM이 환각(hallucination) 문제와 창의력을 동시에 가지고 있다고 분석한다.

The purpose of this study was to verify the effectiveness of an integrated nursing curriculum based on simulation with problem-based learning (PBL) by comparing the clinical competence and the self-confidence of newly graduated nurses. A non-equivalent control group post-test design was employed to compare the clinical competence and the self-confidence in the clinical performance examination using standardized patients between 39 newly graduated nurses with the traditional nursing curriculum and 35 with the integrated nursing curriculum. Data analysis involved Fisher's exact test, t-test, Pearson's correlation coefficient, and ANCOVA with the SPSS 19.0 program. The total clinical competence mean score graded by the standardized patients was not different between the two groups. However, the total clinical competence mean score graded by faculty was significantly higher in the integrated curriculum group than the traditional curriculum group. The mean self-confidence score was significantly higher in the integrated curriculum group than the traditional curriculum group. Active teaching-learning strategies including simulation or PBL in the nursing curriculum could benefit for nursing students by inducing favorable clinical competence and self-confidence. Longitudinal follow-up studies based on observation are needed to explore the patient outcomes in addition to the learner outcomes in clinical settings.

The purpose of this study is to investigate student's Acquisition about the conception of the Earth Rotation between difference of their Spatial Sensibility. In this study, four students were selected out of 83 9th graders in Gwangju, Korea. The spatial sensibility test instrument was developed by the Korean Testing Center, and the test instruments of 'the movement of celestial bodies' were developed by Kim (1997). The results were as follows: Students with higher spatial sensibility understood precisely about the Earth's rotation in stereoscopic space. However, those with lower spatial sensibility failed to grasp the Earth's rotation and memorized it as fragmentary concepts. As for gender effect, male student with higher spatial sensibility explained the concepts clearly, while that with lower spatial sensibility has difficulty with the Earth's rotation in relation to the diurnal motion of celestial bodies. On the other hand, female student with higher spatial sensibility explained the concepts correctly in detail, while that with lower spatial sensibility had difficulty explaining the concepts in stereoscopic space. Therefore, students with higher spatial sensibility should be presented with problems in which they form their own solution. Those with lower spatial sensibility should be allowed to understand the phenomena intuitively. In developing teaching methods, female students should interact with the concepts in stereoscopic space directly, while male students should consider the celestial objects from various viewpoints. Then spatial sensibility in relation to the movement of celestial bodies would be expected to improve.

Purpose: This study was done to develop a scenario and evaluate student performance in simulation learning of care for children with respiratory distress syndrome in neonatal intensive care units. Methods: To test the application effect, a one group pre-test design was applied. The scenario based on actual patients and textbook material was developed through several meetings of experts. The scenario was used with 17 groups of 55 senior nursing students who participated voluntarily. Results: Contents were organized focusing on the nursing process for simulation learning. In the application of knowledge and skills, nursing students had high scores in the contents of observation of oxygen saturation, and care to relieve dyspnea. Participants' ability, especially in suction and oxygen supply in the evaluation of objective structured clinical examination was not adequate. There was a significant positive correlation between problem-solving ability and satisfaction in learning. Conclusion: The respiratory distress syndrome simulation scenario developed in this study was an effective tool to give students experience in problem solving and critical thinking ability under conditions similar to reality. The development of various scenarios for child nursing care is needed.

Objective : The purpose of this study was to compare sensory processing ability by smartphone addiction levels in preschool children, and to investigate the correlation between smartphone addiction level and sensory processing ability within smartphone addiction group. Method : The subjects of this study were 324 persons, with 124 persons in the addiction group and 200 in the normal user group. Measurements in this study were a questionnaire about general characteristics of subject, smartphone addiction scale, and short sensory profile. Methods for the data analysis included descriptive statistics, independent t-test, Pearson correlation analysis of SPSS 22.0. Results : There was a significant difference in the total Short Sensory Profile (SSP) score and in all sub-domains between the addiction and normal use groups (p<0.05). In the smartphone addiction group, there was a negative correlation between the SSP total score (r=-.278), auditory filtering (r=-.293), visual/auditory sensitivity (r=-.393) and smartphone addiction level. Conclusion : This study confirmed that there was a difference in smartphone addiction and sensory processing ability between the preschool children addiction and normal use groups. It has been proven that there is an interrelationship between sensory processing ability and smartphone addiction in the addiction group. It is significant in that it provides basic data to prevent smartphone addiction.

The purpose of this study was to measure the bioactivity and antioxidant activity of peel from Gardenia jasminoides Ellis fructus (GJE). GJE have been known to contain functional materials such as crocin, crocetin, geniposide, gardenosid, geniposidic acid, iridoid glycosides etc. We were separated into GJE peel. After that, we determined proanthocyanidin. GJE peel were extracted by 70% methanol, ethyl acetate (EA) and distilled water (DW) of three solvents. To investigate by the solvent extract of flavonoid content and value as a functional food ingredient of GJE peel through antioxidant activities (DPPH radical scavenging activity, ABTS radical scavenging activity, superoxide dismutase like ability, hydroxyl radical scavenging activity, ferrous ion-chelating capacity) were performed. Solvent extract antioxidant activity of increasing concentrations (0.2, 0.4, 0.6 mg/mL) were significantly increased (p<0.05). GJE peel extracts showed lower activity than positive control (ascorbic acid, BHA, EDTA). These results, by a solvent of peel were found that the relationship with the increase of flavonoid content increased physiological activity. The antioxidant activity of the extract from the other except for the EA extract on peel was observed at a high level. The results suggest that GJE peel can be used as nutraceutical foods and natural antioxidant.

Guineagrass (Panicum maximum Jacq.) is an important warm-season forage grass as well as biomass crop. It has both sexual and asexual mode of reproduction (apomictic) depending on cultivar. We developed efficient plant regeneration system for an apomictic (cv. Natsukaze) and a non-apomictic (Noh-PL1) guineagrass by optimizing the level of L-proline in the callus induction and that of $AgNO_3$ in plant regeneration medium. Among the L-proline concentrations tested, the best callus induction was achieved by using 2g/L L-proline in both the genotypes. Immature embryos proved to be the best explant source for tissue culture of guineagrass. The highest frequency of shoot regeneration was obtained on MS plant regeneration medium supplemented with 2 mg/L $AgNO_3$. These results provide a foundation for efficient tissue culture and genetic improvement of guineagrass.

We investigated biofilm formation in various media, growth in low pH, and the hemolytic activity of 14 strains of Cronobacter spp. (Enterobacter sakazakii) isolated from a variety of foods including powdered infant formula (n=75), infant cereal (n=100), honey (n=30), and other infant foods (n=100) in Korea. The Cronobacter spp. adhered and formed biofilms on polyethylene, and a greater extent of biofilm was observed in nutrient-rich media. No clear difference in biofilm-forming ability was noted among the media constituents and the pattern of biofilm formation was strain-dependent. Seven strains out of 14 strains (50%) grew at pH 4.1, indicating that the acid resistance of these Cronobacter spp. isolated in Korea was relatively low. Hemolytic activity was not observed in any of the strains. This study provides basic information for the physiological and biochemical characteristics of Cronobacter spp. isolated from a variety of infant foods in Korea.
