The subgenus Oropeza Needham, 1908 (Diptera: Tipulidae: Dolichopeza) comprises 27 described species distributed across the Holarctic region. Certain Oropeza species have been reported in neighboring countries of the Korean Peninsula―6 species in Japan, 3 species in China, and 4 species in Russia. Some researchers, such as Byers (1961) and Savchenko (1983), suggested that the distribution of Oropeza cover the East-Palearctic regions, including the entirety of the Korean Peninsula. However, previous records of Oropeza from the Korean Peninsula have not been accepted because of the lack of comprehensive species-level investigations in this region. In this study, we present a new record of the species Dolichopeza (Oropeza) satsuma (Alexander, 1918) in South Korea, with redescription and photographs: general habitus, wing veins, and male genitalia. This finding marks the rediscovery of the subgenus Oropeza in the Korean Peninsula.

In nuclear power plant environments, the analysis of gamma-emitting waste materials with complex shapes can be challenging. ISOCS (In-Situ Objective Counting System) is employed to measure the gamma-emitting radionuclide concentrations. However, it is crucial to validate the accuracy of ISOCS measurements. This study aims to validate the accuracy of ISOCS measurement results for spent filters. The ISOCS measurement process begins with modeling and efficiency calculations of the target spent filters using ISOCS software. ISOCS offers the advantage of direct measurement assessment by incorporating shielding materials and collimators into the detector efficiency calculation during the modeling process, without the need for separate efficiency correction sources. To validate the accuracy of ISOCS measurement results, the measured radioactivity values were used as input data for the MicroShield computer code to derive dose rates. These dose rates were then compared to the dose rates measured on-site, confirming the reliability of ISOCS measurements. In the field, ISOCS gamma measurements and surface dose rates were measured for three Cavity filters and four RCP Seal Injection filters. The measured dose rate for the Cavity filters was around 270 Svhr, and the computed values using MicroShield showed an error of approximately 12%. Despite modeling and calculation errors in computer analysis and potential uncertainties in the measurement environment and instrument, the computed values closely matched the measured values. However, the measured dose rate for the RCP Seal Injection filters ranged 2.9~8 Svhr, which is very low and close to background levels. When compared to the results of computer analysis, an error ranging from 27% to 97% was observed. It is concluded that validating the accuracy in the low dose rate range close to background levels is challenging through a comparison of calculated and measured dose rates.

Currently, in domestic nuclear power plants (NPP), the spent filters (SFs) used for the purpose of reducing and purifying the radiation of the primary cooling water system are temporarily stored in an untreated state. In order to dispose of SFs, radioactive nuclide analysis (RNA) of SFs is required to be conducted. As segmented gamma scanner (SGS) is already being used in Kori NPP, utilizing SGS for RNA of SFs would be practical and economical. In this paper, factors required to be considered to improve accuracy of SGSs for RNA of SFs are studied. The analysis of the nuclide inventory of the packaging drum for radioactive waste should be performed by the indirect drum nuclide analysis method. The material of the SFs is iron (SS304) on the outside, and paper on the inside. In addition, to meet disposal acceptance criteria, radioactive waste drums are packaged in thick grouting or shielding drums. Therefore, it is necessary to derive an appropriate correction method for high inhomogeneity and thick media. Considering these factors, evaluating radionuclides inventory plans to measure gamma rays in SGS mode. Correct the gamma ray measurement by examining the medium attenuation factor and error factors. In this way, the inventory of gamma nuclides is calculated, and the specific radioactivity of beta ray and alpha particle emitting nuclides other than gamma rays is planned to be calculated by applying scaling factors.

Recently, the textile and fashion industry has adopted 3D printing technology, through which filaments are accumulated continuously in the form of sections to produce digitalized three-dimensional fashion products. Little research has been done regarding the consumer perspectives on 3D printed fashion product. Therefore, the purpose of this study was to investigate the effects of consumer innovativeness, uniqueness, and perception factors on consumer attitudes and purchasing intentions for 3D printed fashion products. A questionnaire was given to consumers living in Seoul and Kyunggi, South Korea. The data obtained from the 159 completed questionnaires was analyzed by regression analysis, factor analysis, and Cronbach’s alpha using SPSS 24.0. The results were as follows: First, consumer innovativeness and uniqueness, in descending order, positively affect the perceived social image. Consumer innovativeness positively affects perceived aesthetics and consumer uniqueness positively affects perceived novelty. Second, social image has a positive effect on consumer attitudes to 3D printed fashion products. Third, consumer attitude positively affects purchasing intentions towards 3D printed fashion products. Fourth, consumer innovativeness and uniqueness, in descending order, have a positive effect on consumer attitudes and purchasing intentions for 3D printed fashion products. Fifth, social image and novelty, in descending order, positively affect purchase intentions for 3D printed fashion products. Therefore fashion firms should develop their marketing strategy to focus on innovative, unique consumers as a main target and aim to enhance buyers’ social image by using 3D printed fashion products.

The need for contents that uses motion capture has increased recently. Motion capture realizes the various motions as the data collected through the marker reacts to the characters after being converted to digital data. However, if generalizing the various methods that have been conducted so far, it is somewhat unreasonable to complete animation only with motion capture. The existing motion capture field have been carried out based on the equipment operation and technology development and the advanced research of motion capture-producing pipeline for the production of animation is insufficient as well. This study suggests the realistic animation-producing pipeline by modeling, character setup, calibration, motion capture, data modification and integration of animation for each phase based on such methods.

간이 입체를 인지하는 기저는 상당히 복잡하며 영상의 시각적 요소에 따라 입체감과 편안함이 다르게 인지된다. 따라서 시각적 영상 요소에 따라 다르게 인지되는 영향 인자를 선정하고 이에 대한 공간감과 편안함의 관계를 실험을 통해 분석하였다. 이를 입체 디스플레이에 적용하여 각각의 요소들을 활용한 표현방법에 대한 차이를 두어 분석한 결과 대부분의 시각적 요소들이 입체감을 인지하는데 영향을 미치는 것으로 분석되었다. 이것은 입체감을 습득하는 것이 이미지의 차이에 의한 것 뿐 만 아니라, 이미지에 표현 되어지는 시각적 요소에 따라서도 입체감의 습득에 영향을 미치기 때문에 입체 콘텐츠 제작 시 장면마다 효과적으로 활용하여 표현하는 것이 중요하다는 것을 알 수 있었다.

3D 입체영상 개발에 사용되어지는 여러 가지 공정 중 입체영상 제작방식의 정확한 흐름, 그리고 연출에 대한 이해 가 보다 정확한 입체영상을 제작할 수 있다. 입체에는 실제감, 질감, 공간인식력의 향상 등 여러 가지 효과가 있다. 입 체영상을 제작함에 있어 이들의 효과를 하나의 입체연출로서 이용함으로써 종래의 영상 한계를 넘어선 새로운 표현을 만들 수 있다. 따라서 본 연구에서는 3D 입체영상 제작방식과 연출 프로세스를 살펴보고, 입체영상 제작 시 고려해야 할 시각현상을 보완한 효과적인 입체영상을 제작하는데 그 목적이 있다.

Lilium lancifolium (LL) is widely cultivated in East Asia and used to attenuate airway diseases. Our current study aimed to investigate the therapeutic effect of LL on pain level and inflammatory response in a rat model of monosodium iodoacetate (MIA)-induced osteoarthritis (OA). We first examined the effect of LL on inflammatory cytokines and inflammatory mediators in IL-1β-treated HTB-94 cells. The LL extract was found to significantly inhibit the levels of Interleukin-6 (IL-6), Interleukin-8 (IL-8), and prostaglandin-E2 (PGE-2) in Interleukin-1 β (IL-1β)-stimulated HTB-94 cells in a dose-dependent manner. Moreover, chronic oral administration of LL effectively restored the weight-bearing distribution in the rat model of MIA-induced OA. In addition, administration of LL inhibited inflammatory cytokines and inflammatory mediators, such as C-reactive protein (CRP), IL-6, leukotriene B4 (LTB-4), PGE-2, and matrix metalloproteinase-9 (MMP-9). Our findings collectively suggested LL as one of the potential therapeutic agents for OA, owing to its properties of reducing pain and inflammatory responses.
