Genetic linkage maps have become an indispensable tool for genetics and genomics research. Sea cucumber (Apostichopus japonicus), which is an economically important mariculture species in Asia, is an edible echinoderm with medicinal properties. In this study, the first SNP-based high-density genetic linkage map was constructed by sequencing 132 A. japonicus individuals (2 parents and 130 offspring) according to a genotyping-by-sequencing (GBS) method. The consensus map was 3181.54 cM long, with an average genetic distance of 0.52 cM. A total of 6144 SNPs were assigned to 22 linkage groups (LGs). A Pearson analysis and QTL mapping revealed the correlations among body weight, body length, and papillae number. An important growth-related candidate gene, protein still life, isoforms C/SIF type 2 (sif), was identified in LG18. The gene was significantly highly expressed during the larval developmental stages. Its encoded protein reportedly functions as a guanine nucleotide exchange factor. These results would facilitate the genetic analysis of growth traits and provide valuable genomic resources for the selection and breeding of new varieties of sea cucumbers with excellent production traits.

In painting, line is one of the basic compositional elements and an important "tool" for artists to express their ideas. The combination of line and color, composition, and shape allows the viewer to feel the author's thoughts, emotions, or distinctive thinking through the picture. Foreign cave paintings, European pre-Renaissance oil paintings and modern paintings, and domestic Dunhuang murals, silk paintings of the Warring States period and cave paintings all show that the contour line has never disappeared despite its different roles in the changing times. Therefore, the artist's generalized expression of contour lines can become a characteristic of the picture that makes the artist stand out.

This chapter examines the role of images in the Roman domestic sphere, focusing on the contribution of paintings, mosaics, and other forms of representation to the construction of the Roman house as a place of self-representation and social interaction. Images were essential to the purposes of both shaping the environmental quality of domestic spaces and informing visitors about their character, function, and the behavior that was required from them. The case study of an apparently minor genre of Roman wall painting, that of still-life pictures (i.e., images of food and silverware), allows in-depth discussion of how the choice and understanding of subject matters depended on and relied upon shared mechanisms of recognition, as well as a tight semantics of meanings, values, and habits.

The Chinese themes in Early American art have long been obscured under the veil of Japonisme, Aesthetic movement, boundary-pushing modernism and more significantly because of the political circumstances - decline of China as an empire and complicated Chinese-American interconnections. One of the favoured theme of American academism at the period of the late 19th- early 20th centuries were genre scenes, street scenes, portrait d’intérieur , portraits, still life works related to China and Chinatowns. Nonetheless, the American press through the imagery created by illustrators and caricaturists was largely involved in interpretations of Western encounters with Chinese culture from the highlighted negative light, either being deeply affected by anti-Chinese flows or fuelling those xenophobic moods. Consequently, a few American artists featured Chinese people and Chinese settings from the perspective of admiration of their “otherness”. Only two American artists- Katherine A. Carl and Hubert Vos, succeeded to pave their career path to the Chinese court, enriching American arts of the early 1900s with the unprecedented depictions of high rank Chinese and the scandalously renowned empress Dowager Cixi (1835-1908) in the positive light of fascination. A number of publications have viewed and examined those portraits from the angle of "political self-fashioning”, but our research is another academic attempt to place those oil paintings in the context of China-related subject matter and its extension in the rising American art of the previous century, stressing their artistic value, function and their relations to the intended audiences.

Pelajar didapati sukar melukis bentuk objek khususnya bentuk geometri dan tidak dapat menentukan arah cahaya dan saiz bayang yang tepat semasa melukis. Ini menyebabkan lukisan tidak nampak relistik dari segi bentuk dan konteks pencahayaan. Kajian ini bertujuan untuk mengkaji penggunaan display light board (DLB) dalam meningkatkan kemahiran teknik melukis bentuk geometri secara ‘still life’. Display Light Board menggabungkan unsur cahaya dan latar belakang putih untuk menimbulkan kesan cahaya dinamik dan dramatik kepada bentuk-bentuk geometri yang diletakkan di atasnya. Kajian secara kualitatif dijalankan terhadap 10 orang pelajar tingkatan 4 yang dipilih secara persampelan bertujuan. Data dikumpul menggunakan kaedah pemerhatian dan kajian dokumen. Satu alat inovasi iaitu Model DLB digunakan untuk membantu meningkatkan kemahiran pelajar untuk melukis cahaya dan bayang dengan tepat. Lampu dinyalakan ke arah bentuk-bentuk geometri yang diletakkan diatas papan, sehingga terhasil kesan cahaya dan bayang yang dapat dijadikan panduan kepada pelajar untuk melukis bentuk yang efektif. Hasil penggunaan model DLB  menunjukkan 100% pelajar mudah melihat dan faham arah cahaya serta bentuk bayang yang terhasil daripada cahaya lampu yang dipasang. 90 % daripada mereka dapat melukis objek dengan baik dengan mengenal pasti kedudukan bayang yang tepat pada objek. Justeru, kajian mencadangkan supaya Model  DLB ini dapat digunakan oleh pelajar untuk memahami konsep melukis objek dengan tepat secara ‘still life’ dengan adanya kesan cahaya dan bayang yang jelas. Guru dapat menadikan DLB ini sebagai bahan bantu mengajar yang sesuai untuk meningkatkan pencapaian pelajar.
