To develop an effective and efficient measurement system for tracking changes of functional status across two measures, it is essential to integrate information and communicate scores across two measures. The lack of communication between two measures leads to score incompatibility. A potential solution would be the development of a crosswalk table between those measures. Prior to creating a crosswalk table, selecting common items between two measures is critical. By using the Oswestry low back pain disability questionnaire (Oswestry) and a short form measuring disability resulting from low back pain, item level statistics as well as differential item functioning (DIF) using the Rasch measurement were investigated. Eighty-two participants with known group validity were recruited. Based on the application of the Rasch measurement model, item difficulties across the two measures were logically and hierarchically ordered. Ceiling effects for both measures were detected, which were not be able to be effectively measured with the two measures. The DIF analysis across the two measures confirmed that five paired items were found to have DIF and five common items were selected for common items. Although five paired items function differently across the Oswestry and the short form, all items of both measures were well targeted study participants. The common items selected by the Rasch measurement model may be effective when creating a crosswalk table between the Oswestry and the short form.

4차 산업혁명과 팬데믹은 비대면 서비스에 대한 의존도를 높이는 결정적인 계기가 되었다. 이에 본 연구는 현재 디지털 네이티브 세대를 중심으로 각광 받고 있는 숏폼 브랜디드 콘텐츠에 대해 논의함으로써 비대면 마케팅에 대한 새로운 전략 방안을 도출하고자 하였다. 특히 소셜 미디어 상에서 숏폼 브랜디드 콘텐츠를 공유하고 소통하는 사회적 시청 현상을 중심으로 노출 유형 (직접 시청 vs. 사회적 시청)이 숏폼 브랜디드 콘텐츠와 콘텐츠가 포함하고 있는 제품에 대한 태도에 어떠한 영향을 미치는지 검증하였다. 더불어 인지된 소속감을 매개 변인으로 제시하고, 사회적 시청 과정에서 소비자가 인지하는 소속감이 노출 유형과 소비자 태도 간의 관계에서 유의한 매개 효과를 주는지 실험을 통해 확인하였다. 연구 결과, 노출 유형은 콘텐츠와 콘텐츠가 포함하고 있는 제품에 대한 태도에 유의한 영향을 미쳤으며, 또한 인지된 소속감 역시 매개 변인으로서 유의한 것으로 나타났다.

본 연구는 코로나19로 인해 모바일을 통한 숏폼 콘텐츠 소비가 증가한 상황에서, 중국의 대표적인 숏폼 플랫폼인 틱톡에서 여행 관련 콘텐츠가 사용자들의 여행 목적지와 여행상품에 대한 방문 의도에 미치는 영향을 조사했다. 2023년 7월에 중국 온라인 설문 기관을 통해 337명을 대상으로 조사를 실시한 결과, 틱톡의 콘텐츠 특성 중 오락성은 관광지 이미지에 영향을 미치지 않았으나, 정보성과 신뢰성은 긍정적인 영향을 미치며, 전문성과 상호작용성도 긍정적인 영향을 미친 것으로 나타났다. 이렇게 숏폼 콘텐츠를 통해 형성되는 관광지 이미지는 방문 의도에 긍정적이고 유의한 영향을 미쳤다. 이 결과는 관광지 및 마케팅 전략 수립 시 고려할 중요한 정보로 활용될 수 있다.

For the development of a short form of the Korean Wechsler Preschool and Primary Scale of Intelligence (K-WPPSI), 360 preschool and primary school children were tested with 4 subtests: Object Assembly, Arithmetic, Block Design, and Comprehension. Transformed scores were derived according to K-WPPSI norms. Interscorer reliability coefficients measured by two independent scorers with the data of 16 children were satisfactory: Comprehension, .92; Arithmetic, .94; Block Design, .97; Object Assembly, .97 Cronbach alpha reliability coefficient for the 4 subtests were very similar to those for the original K-WPPSI, ranging between .71 and .92. Factor analyses revealed 2 factors corresponding to Wechsler's 2 factor theory of intelligence. Discriminant validity was obtained with a Picture-Vocabulary test. Boys performed slightly better than girls on all subtests except for Comprehension. Boys significantly out-performed girls in Arithmetic.

In visible light (VL) positioning based on angle of arrival (AOA) estimation for smart indoor service, the AOA parameters obtained at the receiver has sometimes a random and distributed angle form instead of a point angle form due to the multipath transfer of the actual visible light and short positioning distance. The AOA estimation of a VL signal with a random and parametric distributed angle form may give incorrect AOA parameter estimates, which may result in poor VL positioning performance. In this paper, we classify the AOA parameters of the received VL signal into three forms according to the actual positioning channel environment and consider the short-range VL positioning method. We propose a subspace-based AOA parameter estimation technique and a data fusion method, and analyzed the proposed method by simulation and the measurement of the real VL channel characteristics.

Objectives The purpose of this study was to analyze the difference of cold-heat pattern according to sasang constitution. Methods 3891 subjects were joined in this study. The sasang cinstitution diagnosis were proceeded by sasang constitution experts. The questionnaires and anthropometric measurements of the subjects were collected. Results The effect of gender and body mass index on the cold-heat pattern according to sasang constitution were significant. The effect of age on the cold-heat pattern according to sasang constitution were not significant. The distribution of short form-12 and blood test on the cold-heat pattern according to sasang constitution were significant. Conclusions There were significant different distribution of cold-heat pattern asscording to sasang constitution by gender, body mass index, short form-12, blood test.

본 연구는 한국 사회에 적용될 수 있는 한국 단축형 사랑중독 척도(Korean-Love addiction Questionnaire-Short Form: K-LAQ-SF)를 타당화하기 위해 수행되었다. 이를 위해 Peabody(2005)의 사랑중독 질문지(Love addicts 40 Questions)를 바탕으로 탐색적 요인분석을 통해 최종 5요인, 15문항을 선정한 뒤, 확인적 요인분석을 통해 최종 척도의 모형 적합도를 확인하였다. 동등성 검증 결과는 축약된 척도의 이론적 구조가 남녀별로 동일한 방식으로 작동하고 있음을 나타내었다. K-LAQ-SF와 원척도와의 상관분석 결과는 본 척도에서 타당화된 단축형 척도가 원척도를 비교적 충실히 대표하고 있음을 나타냈다. 마지막으로 관계중독, 사랑유형, 우울 변인과의 상관분석 결과 통해 수렴, 변별 및 준거타당도를 확보하였다. K-LAQ-SF는 안정적인 신뢰도와 타당도를 바탕으로 짧은 시간에 간편하게 한국 성인의 사랑중독 특성을 측정하는데 유용하게 활용될 수 있다는 점에서 의의가 있다.

Objectives This study was performed to make a short-form of Sasang Constitution Questionnaire for Patient(SSCQ-P). Methods In order to select important questions of SSCQ-P, we got advice from 10 professors of Oriental Medicine. As a result, we chose 37 questions. In addition, we selected 69 questions which had been used more than 12 times in SSCQ-P as the variable. We used some statistical methods to reduce questions. Finally, a total of 40 questions were selected. To find diagnostic accuracy rate of this short-form, discriminant analysis was performed. We used 1378 cases which was collect ed from February 2008 to June 2013 by online system(Sasang-medi data which has selected by web site, http://www.sasangmedi.or.kr), and 68 cases which was collected from November 2006 to September 2007 by the research "Construction of a biological information collection system for the Constitutional scientific diagnosis"(Korea Constitutional Multicenter Bank data, KCMB data) Results We made a short-form of SSCQ-P consisting of 40 questions. Diagnostic accuracy rate of short-form is 66.18% using Sasang-medi data, and 42.65% using KCMB data. Conclusions More cases are needed to improve the diagnostic accuracy rate of this short-form.

Photosynthetic dinoflagellates contain a water-soluble, light-harvesting antenna called the peridinin-chlorophyll-protein (PCP) complex, which has an apoprotein with no sequence similarity to other known proteins. There are two forms of PCP apoproteins; the 15-kDa short form and the 32- to 35­kDa long form. The present study describes the PCP protein and its cDNA from Alexandrium tamarense. A cDNA library was constructed from mRNA isolated from A. tamarense. The complete PCP cDNA was generated by reverse-transcription coupled to polymerase chain reaction (RT-PCR), together with rapid-amplification of cDNA ends (RACE). The A. tamarense PCP cDNA encoded a 55-amino acid signal peptide and a 313-amino acid mature protein with a calculated mass of 32 kDa, which corresponded to that of the long form of PCP. Phylogenetic analysis indicated that the sequence of A. tamarense PCP did not cluster with the short-form PCPs, to which it was only about $55\%$ identical, but which were $79-83\%$ identical to other long-form PCPs. The deduced amino acid sequence of A. tamarense PCP contains an internal duplication, which suggests the possibility that long-form PCPs arose by gene duplication or by the fusion of genes encoding the short form. The abundance of PCP mRNA changed substantially in response to different light conditions, indicating the possible existence of a photo-acclimation response in A. tamarense.

This paper deals with short-term load forecasting. The load model is represented by the state variable form to exploit the Kalman filter technique. The load model is derived from Taylor series expansion and remainder term is considered as noise term. In order to solve recursive filter form, among various algorithm of solving Kalman filter, this paper uses exponential data weighting technique. This paper also deals with the asymptotic stability of filter. Case studies are carried out for the hourly power demand forecasting of the Korea electrical system.
