The study was conducted to develop two parallel short forms for the Convergent thinking and Problem solving questionnaires which are part of H University's core competency diagnostic tools, based on Multi-Item Response Theory. Item responses of 2,580 students were analyzed using Graded Response Model(GRM) to determine item difficulty and discrimination of each item. The research results are as follows. Two parrallel short tests were developed for the Convergent thinking questionnaire consisting of 12 items which were originally 17 items. Likewise, the Problem solving questionnaire, which originally consisted of 15 questions, was divided into two parallel short forms, each consisting of 9 items. The reliability of the shortened parallel tests was confirmed through internal consistency analysis, and their similarity to the original tests was established through correlation analysis. This study contributed to quality management of competency-based education and programs at H University by developing shortened tests. Based on the results, implications were presented as well as limitations and discussions.

The outbreak of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is spreading globally, and the WHO has declared this outbreak a pandemic. Vaccines are an effective way to prevent the rapid spread of COVID-19. Furthermore, the immune response against SARS-CoV-2 infection needs to be understood for the development of an efficient and safe vaccine. Here, we review the current understanding of vaccine targets and the status of vaccine development for COVID-19. We also describe host immune responses to highly pathogenic human coronaviruses in terms of innate and adaptive immunities.

Near-field source localization algorithms are very sensitive to sensor gain/phase response errors, and so it is important to calibrate the errors. We took into consideration the uniform linear array and are proposing a blind calibration algorithm that can estimate the directions-of-arrival and range parameters of incident signals and sensor gain/phase responses jointly, without the need for any reference source. They are estimated separately by using an iterative approach, but without the need for good initial guesses. The ambiguities in the estimations of 2-D electric angles and sensor gain/phase responses are also analyzed in this paper. We show that the ambiguities can be remedied by assuming that two sensor phase responses of the array have been previously calibrated. The behavior of the proposed method is illustrated through simulation experiments. The simulation results show that the convergent rate is fast and that the convergent precision is high.

A dimensionality assessment procedure DETECT uses the property of being near zero of conditional covariances as an indication of unidimensionality .This study provides the convergent properties to zero of conditional covariances when the dta is unidimensional, with which DETECT extends its theoretical grounds.

Purpose: This study aimed to develop the following scales on women's environmental health and to examine their validity and reliability: severity, susceptibility, response efficacy, self-efficacy, benefit, barrier, personal health behavior, and community health behavior scales. Methods: The item pool was generated based on related scales, a wide literature review, and indepth interviews on women's environmental health according to the revised Rogers' protection motivation theory model. Content validity was verified by three nursing professionals. Exploratory factor analysis, convergent validity, and internal consistency reliability were examined. Results: The scales included 10 items on severity, 11 on susceptibility, 10 on response efficacy, 14 on self-efficacy, 8 on benefits, 10 on barriers, 17 on personal health behavior, and 16 on community health behavior. Convergent validity with the environmental behavior scale for female adolescents was supported. The Cronbach's α values for internal consistency were good for all scales: severity, . 84; susceptibility, .92; response efficacy, .88; self-efficacy, .90; benefits, .91; barriers, .85; personal health behavior, .90; and community health behavior, .91. Conclusion: The evaluation of the psychometric properties shows that these scales are valid and reliable measures of women's environmental health awareness and behaviors. These scales may be helpful for assessing women's environmental health behaviors, thereby contributing to efforts to promote environmental health.

Bilateral convergent strabismus with exophthalmus(BCSE) is an eye disorder affecting many cattle breeds worldwide. BCSE is the most common in cattle at various types of strabismus. Divergent strabismus is of relatively low incidence than convergent strabismus. This report is the to shown a case of convergent and divergent strabismus with unilateral in the exophthalmus in a heifer Holstein cow. A female Holstein calf born with congenital progressive divergent strabismus in right eye and convergent strabismus in left eye was tested. Ocular and blood examination, and activity were checked from the first week, 8 month, and 16 month after birth. The ocular examination includes general inspection, fixation reflex and menace response. The general inspection is checking the degree of deviation of both eyes from the normal visual axis, which was determined by the amount of sclera permanently visible in the temporal corner of the eye. The stage is divided into 4 stages depending on the degree of deviation. The right eye shown in stage 4 continues after birth and the left eye shown stage 2, stage 3 and stage 4 at 1 week, 8 month and 16 month after birth, respectively. In fixation reflex and Menace response, both eye balls showed a normal response at 1 week, 8 month and 16 month after birth. Blood count and serum chemistry test were performed, but a specific factor was not detected outside the reference range.

키네틱 교육(Kinetic education)은 모션을 인식하는 디지털 기기인 체감형 게임기(motion based game device)를 사용하여 교육행위에 운동성을 접목하는 융합형 교육방안이다. 본 논문은 키네틱 교육의 필요성과 의미를 탐색하고, 영미문학 서사 교육, 전신반응 활동에 기반을 둔 스토리텔링(Total Physical Response-Storytelling) 교수법의 특성을 상보적으로 결합시켜 새로운 방식의 디지털교육 콘텐츠의 방향성을 제안해보고자 한다. 이러한 '영문학 기반 키네틱 교육 콘텐츠' 기획을 위한 구체적인 방안과 예시는 '아기돼지 삼형제'(The Story of the Three Little Pigs) 동화를 활용하여 1) 어린이 영문학 작품 선정 및 분석, 2) 콘텐츠 프로토타입 설계 및 개발, 3) 동작 데이터베이스 구축 세 단계로 구분하여 제시하였다. 본 연구는 서사문화 교육과 스토리텔링의 문화콘텐츠 개발을 위한 새로운 융합적 모형을 제안할 것으로 기대된다. 영문학 서사 기반의 키네틱 콘텐츠의 교육적 연계성과 인문학적 가치를 부연하였다.

Oil spills pose significant threats to marine ecosystems, human health, socioeconomic aspects, and coastal communities. Accurate real-time predictions of oil slick transport along coastlines are paramount for quick preparedness and response efforts. This study used an open-source OpenOil numerical model to simulate the fate and trajectories of oil slicks released during the 2007 Hebei Spirit accident along the Korean coasts. Six combinations of input parameters, derived from a five-day met-ocean dataset incorporating various hydrodynamic, meteorological, and wave models, were investigated to determine the input variables that lead to the most reasonable results. The predictive performance of each combination was evaluated quantitatively by comparing the dimensions and matching rates between the simulated and observed oil slicks extracted from synthetic aperture radar (SAR) data on the ocean surface. The results show that the combination incorporating the Hybrid Coordinate Ocean Model (HYCOM) for hydrodynamic parameters exhibited more substantial agreement with the observed spill areas than Copernicus Marine Environment Monitoring Service (CMEMS), yielding up to 88% and 53% similarity, respectively, during a more than four-day oil transportation near Taean coasts. This study underscores the importance of integrating high-resolution met-ocean models into oil spill modeling efforts to enhance the predictive accuracy regarding oil spill dynamics and weathering processes.

본 논문에서는 ADHD 진단을 해주는 전문가시스템을 설계 및 구현한다. DSM-IV-TR을 이용하여 ADHD 진단기준을 연령대에 따라 단어를 바꾸어 구체화한다. 이 진단지를 가지고 오브젝트와 해당 값을 설정하고 규칙을 생성한다. 그리고 'ADHD 진단 시스템 엔진'과 '사용자 질의응답 프로그램'으로 구성된 진단시스템을 설계한다. 'ADHD 진단 시스템 엔진'은 규칙 기반 추론 엔진으로 Prolog 언어로 구현하여, INPUT을 '사용자 질의응답 프로그램'으로부터 받는다. INPUT에 의해 규칙은 ADHD 진단기준을 기반으로 점화되며 진단결과를 추론해서 OUTPUT을 다시 '사용자 질의응답 프로그램'으로 보낸다. '사용자 질의응답 프로그램'은 Python 언어로 구현하여 사용자와의 대화를 처리하는 인터페이스 역할을 한다. 'ADHD 진단 시스템 엔진'과 '사용자 질의응답 프로그램'의 중간다리 역할을 Pyswip 라이브러리를 통해서 수행한다. 결과적으로 ADHD 진단 전문가시스템을 통해 진단비용 절감과 간편한 이용으로 치료계획에 도움을 주고자한다.
