본 연구는 매화나무의 새로운 품종인 대홍의 식품학적 가치평가를 분석하기 위해 일반성분, 유리당, 유기산, 아미노산, 무기질 및 비타민 함량 등을 분석하였다. 대홍의 탄수화물은 46.8±0.92%로 가장 높은 함량을 보였고, 조단백질(18.9±0.01%), 수분함량(11.8±0.13%), 조섬유·조지방·회분(5.7±0.94∼ 6.7±0.52%)순으로 검출되었다. 유리당은 5종 검출되었고 mannitol과 fructose가 대부분을 차지하였고, 무기질은 6종이 검출되었으며, K와 P의 함량이 가장 높게 나타났다. 총 페놀함량은 615.99±0.52 mg/100g 이었고 7가지 유형의 필수 아미노산을 포함하여 대홍의 총 아미노산 함량은 121.42 mg/g이었다. 이러한 결과는 대홍이 건강을 위한 혁신적인 식품으로서 혹은 천연식품 방부와 대체재로서 새로운 제품에 포함될 수 있는 가능성을 보여준다.

The purpose of this study is to evaluate the attributes of consumers global luxury fashion brands and to find the impact of consumer value, meaning the social and pleasure values derived from brands on product purchase involvement. The method in this study was analysis of a total of 298 responses to a questionnaire. The results indicate, first of all, that among the attribute evaluations of global luxury brands, traditionality and splurge affect purchasing involvement. However, prestige and originality were found to have no influence on purchasing involvement. Second, the responses to the questionnaire indicate that social and pleasure values had a statistically significant effect on purchase of luxury brands. Third, the value of cross-group attributes evaluation and consumption value to differences in purchase involvement has had statistically significant results. In conclusion, the traditional and Splurge natures of the luxury global fashion industry’s brand, social consumption value and pleasure consumption value affect the level of purchase involvement. This underscores the importance of attribute Evaluation(traditional and splurge) and consumption value(social and pleasure) when planning consumer marketing strategies for global luxury fashion brands in the future.

Royal jelly (RJ) is a gelatinous substance that bees produce to feed bees and queen bees. It’s frequently sold as a dietary supplement to treat a variety of physical ailments and chronic diseases. While it has long been used in traditional medicine, its applications in Western medicine remain controversial. The inhibitory effect of royal jelly on osteoarthritis was investigated in primary cultured rat cartilage cells and monosodium-iodoacetate (MIA)-induced arthritis rat model 10-hydroxy-2-decenoic acid (10-HAD) is the main fatty acid present in RJ. Among the criteria for RJ quality analysis, 10-HAD content has been proposed as a freshness parameter. We investigated the effect of RJ on the improvement of osteoarthritis on SD rats and they were divided into five groups. In this study, we examined the effect of enzymatic royal jelly (ERJ) administration on osteoarthritis. To determine the antiinflammatory effects of RJ, tumor necrosis factor alpha (TNF-α) and Interleukin-6 (IL-6) expression were measured after lipopolysaccharide (LPS) activation in RAW 264.7 cells. In in vivo animal study, osteoarthritis was induced by intra-articular injection of MIA into knee joints of rats. As a results, ERJ showed that TNF-α and IL-6 levels were decreased by ERJ treatment in a dosedependent manner. In conclusion, ERJ extract was able to inhibit articular cartilage degeneration by preventing extracellular matrix degradation and cartilage cell damage. It was considered that ERJ extract may be a potential therapeutic treatment for degenerative osteoarthritis.

Dentin hypersensitivity (DH) is defined as short and sharp pain caused by external stimuli such as heat, vaporization, contact, osmotic pressure, and chemical stimulation in a normal tooth, rather than due to disease or tooth damage. Its solution is to block the flow of dentinal fluid by physically blocking the dentinal tubule. Of these treatments, fluoride and oxalate type for hypersensitivity can only have a temporary effect. Resins should be used with a suitable bonding system and they may cause hypersensitivity symptoms after treatment. Overcoming these limitations, there is a need for method that can effectively treat dental hypersensitivity lasting long without any side effects. For this reason, experiments with 200 plant extracts as candidates for dentin hypersensitivity, Buddleja officinalis was considered as a candidate for present study. The purpose of this study is to confirm whether the ethanol extract of Buddleja officinalis is effective to protect enamel and dentin by coating tooth surface and resistance to acid or alkali even after tooth coating.

After the permanent shutdown of K1 in 2017, decommissioning processes have attracted great attention. According to the current decommissioning roadmap, the dismantling of the activated components of K1 may start in 2026, following the removal of its spent fuel. Since the reactor vessel (RV) and reactor vessel internal (RVI) of K1 contain massive components and are relatively highly activated, their decommissioning process should be conducted carefully in terms of radiological and industrial safety. For achieving maximum efficiency of nuclear waste management processes for K1, we present activation analysis of the segmentation process and waste classification of the RV and RVI components of K1. For RVI, the active fuel regions and some parts of the upper and lower active regions are classified as intermediate-level waste (ILW), while other components are classified as low-level waste (LLW). Due to the RVI’s complex structure and high activation, we suggest various underwater segmentation techniques which are expected to reduce radiation exposure and generate approximately nine ILW and nineteen very low level waste (VLLW)/LLW packages. For RV, the active fuel region and other components are classified as LLW, VLLW, and clearance waste (CW). In this case, we suggest in-situ remote segmentation in air, which is expected to generate approximately forty-two VLLW/LLW packages.
