Recently, silk farming trends are changed from silk production to functional production because of a slump in only silk production. The 'Functional silk farming production promotion and assistant ACT', which has been enacted and effective since 2009, provides an environment to create the integrated functional sericulture production program. The purpose of this study is to derive the current industry status and the development strategy resulting in promoting and creating a new value-added industry. The main items to be improved in current sericulture industry are production infra and facilities, post-harvest storage technology, processing and marketing, sericulture farming products trading, exporting and merchandised promoting, farm management and farm income etc. Future sericulture industry should be focus on Mulberry production and Processing instead of silk farming only for a new valued added industry.

The present study investigated the feasibility of using the ethanolic extract of Hermetia illucens larvae (HIE) as a whitening improvement material. In cell viability assays using B16F1 melanoma cells, no cytotoxicity was recorded up to 200 ㎍·mL^-1 of HIE. Moreover, while tyrosinase inhibitory activity increased, melanin content decreased in a dose-dependent manner, indicating that HIE likely inhibited tyrosine-induced intracellular melanin biosynthesis in B16F1 melanoma cells. Therefore, HIE is expected to serve as a potent whitening improvement material.

The purpose of this study is to organize research trends by analyzing healing studies using emotional insects, and to suggest future research directions. As a result, only six emotional insect species were used for healing purposes, and most of the age groups of the test subjects were elementary school students and the elderly. As for the type of research, field application of the healing program was dominant at 76.5%. Effectiveness verification was mainly conducted through questionnaires before and after participating in the healing program. In some cases, stress-related salivary hormones were used as indicators or clinical tests were conducted by medical staff. Based on the results of this analysis, future strategies such as finding new emotional insect species, developing various types of healing program models, and expanding and subdividing the target subjects were suggested to promote the growth of the healing industry using emotional insects in the future.

This study aimed to investigate the psychological effect of a healing agricultural program using insect resources and to confirm the persistence of the healing effect. The applied insect was silkworm Bombyx mori (Linnaeus) and 28 adolescents from local children's centers were used as the subjects. The healing agricultural program was applied at the centers for 4 weeks, and stress was measured using salivary α-amylase levels and a survey on life satisfaction, happiness, and insect preference. The results indicated that stress levels decreased, and life satisfaction and insect preference increased after participating in the the healing agricultural program. Furthermore, it was confirmed that this healing effect continued until 4 weeks after the end of the program.

We introduce a method for preserving yellow mealworm (Tenebrio molitor Linnaeus) larvae for an extended period and show that a high percentage of larvae can survive in good health under low-temperature storage conditions combined with specific diapause termination conditions. Our study revealed that we can regulate important development stages such as pupation, emergence, and larval duration by adjusting these termination conditions. When storing larvae aged 6-8 weeks for 140 days, the storage temperature can be varied based on our goals, giving us control over yellow mealworm production to meet specific demands. To produce adult beetles, storing larvae at 15 ℃ with wheat bran and ending diapause at 30 ℃ resulted in 90% pupation rate, with 60% becoming adults in 21 days. If our aim is larvae production, storing them at 10-12 ℃ with wheat bran and ending diapause at 25-30 ℃ allows the larvae to reach a suitable weight for processing. This straightforward approach ensures long-term storage of yellow mealworm larvae and provides a practical way to control their development, allowing efficient mass production tailored to market demands.

5.16 군사정부의 탄생과 함께 적지 적산주의 권농정책에 힘입어 오늘날 크게 발전을 보게된 한국의 양잠업은 사실인즉 이조중엽까지만 하여도 전국 방방곡곡에 크게 번성하였던 민족산업의 하나이었다. 그러나 이조말 서정이 혼탁하면서 강요되기 시작한 가혹한 공납행위와 정상배에 의한 수탈행위의 혹독함에 견디다 못한 생산농민은 뽕나무를 "병민지초"라 부르는 일방, 나무뿌리에 몰래 독즙을 주입하여 자연고사케 함으로써 관으로부터 양잠농을 패업한데 대한 직접적인 질분을 피하면서 가혹한 수탈대상으로부터 가까스로 탈출에 성공할 수 있었다. 그리하여 천혜의 양잠적지가 상전벽해로 되버린 쓰라린 역사를 다시 거슬러 극복하고 1960연대에 이르러 번영의 잠업농으로 재구축하여 놓은 것이다.

우리나라의 잠사업은 농가의 소득증대와 수출산업으로서 계속 성장해 왔다. 그러나 지금까지는 양적인 광대에 치중한 나머지 질적인 면에서 미흡한 점이 있어 국제수준에 비하면 그생산수준이 상당히 낮은 실정에 있다. 그러므로 잠사업이 계속 안정된 산업으로 성장발전해 나가자면 무엇보다 생산량과 직결되는 양잠농가의 기술적인 개량과 경영의 합리화를 꾀하여 생산성의 향상을 기하고 생산비를 절감하여 농가의 실질소득을 증대시키는 동시에 국제시장에 있어서의 경쟁력을 강화해야 할 것이다.(중략)

The study aimed to investigate the psychological effect of the emotional insect-assisted healing program on the stress experienced by 43 children in a community child center. Silkworm (Bombyx mori [Linnaeus]) was used in the healing programs, and the stress was measured using salivary alpha-amylase levels. Saliva samples and a survey on insect preference were collected before and after the healing programs, respectively. After the program, the satisfaction score for participation was evaluated. Results indicate that the emotional insect-assisted healing programs led to statistically significant lowering of salivary alpha-amylase levels and increased the preference for insects. The children's satisfaction in the healing program activities using silkworms was 4.23 points out of 5.
