해양치유 프로그램에 대한 관심은 코로나19 팬데믹 이후 정부와 업계 실무자 모두에서 급속도로 증가하고 있다. 그러나 아직까 지 소비자 관점에서 해양치유 프로그램이나 해양치유 체험에 대한 유용성, 만족도, 편익 등을 이해하고자 시도한 연구는 부족한 실정이 다. 이에 이 논문에서는 후기수용모델을 적용하여 해양치유 프로그램 참여자의 지각된 유용성과 기대일치, 만족, 지속참여의도 간 관계를 구조적으로 분석하고자 하였다. 자료수집은 부산시 해양치유 프로그램 운영 기간인 2022년 9～10월까지 매 주말 사전 훈련된 면접원에 의 한 면접조사 방식으로 실시하였고, 총 203부의 유효 표본을 분석에 활용하였다. 분석 결과 해양치유 프로그램에 대한 기대일치는 프로그 램 참여자의 만족과 프로그램의 지각된 유용성에 긍정적인 영향을 미치는 것으로 나타났고, 해양치유 프로그램 참여자 만족은 프로그램 지속참여의도에 긍정적인 영향을 미치는 것으로 나타났다. 해양치유 프로그램에 대한 지각된 유용성 역시 프로그램 참여자 만족 및 지속 참여의도에 긍정적인 영향을 미쳤다.

Background: The hyoid bone is the only non-jointed structure among the skeletal tissues of the head and neck region, and its movement and posture depend on the attached muscle, ligament, and fascia. The location of the hyoid bone is important for airway maintenance, vocalization, chewing, swallowing, breathing, and head and scapular position. In general, the location of the hyoid bone is measured using radiographs and 3D computed tomography, and no studies have reported on clinical measurement methods. Objects: This study was performed to suggest clinical measurement methods for lateral deviation of the hyoid bone and to evaluate their reliability. Methods: In this study, 24 healthy volunteers (12 males, 12 females) in Cheongju-si participated. Two examiners performed the center point test and lateral motion test twice each to measure the lateral displacement of the hyoid bone. The reliability of the center point test was analyzed using intra-class correlation coefficients (ICC), and the reliability of the lateral motion test was analyzed using Cohen’s kappa coefficient. Results: The intra-rater reliability of the center point test was good, and the inter-rater reliability was moderate. The intra- and inter-rater reliability of the lateral motion test showed substantial reliability. Conclusion: Based on these results, the center point test and the lateral motion test can be used as an alternative methods of the measurement of lateral deviation of the hyoid bone for people who have musculoskeletal disorders of the head, neck, and scapula.

Research on salinity stress has strongly increased over the last decade, as salinity stress is a main key factor limiting the global crop production in many regions of the world. In recent years, it is possible to obtain a large amount of genotypic data in a short time due to a reduction in genotyping costs. This wave of genomic information has effected the development of new strategies for the integration of molecular information in breeding programs. However, phenotyping is still a manual activity, and different from each species, environment, and trait. It often generates high labor costs, and can be sensitive to environmental changes, and sometimes includes the individual biased assessments from different people. There is a strong demand for phenotypic data of high quality. The current objective of phenomics is phenotyping a large number of individuals for many traits in a nondestructive manner and with good accuracy. Here we described the image-based technology as applied to alleviate the bottleneck for the development of high-throughput phenotyping platforms. Several trials to measure stress responses of rice plantlets based on image data under the salinity condition are underway to develop automation for the next-level of phenotyping.

Rice is one of the most important cereal crops in the world and a model plant for functional genomics of monocotyledon. Recently, rice crop loss is estimated to be approximately 30% of the total yield due to herbivorous pests, mainly insects. Cry1Ac toxin is a protein produced by the bacterium Bacillus thuringiensis and has insecticidal properties. CryBP1 toxin also is an insecticidal protein produced by the bacterium Bacillus popilliae. These two toxic genes derived bacteria, which were inserted into a binary vector, have been introduced into rice plants by Agrobacterium tumefaciens mediated transformation in order to enhance resistance to insects. Here, we utilized anthers to regenerate transgenic rice plants when it has been plated on the callus induction media as a callus-inducing material. Anther culture has a benefit in terms of being apt to produce doubled haploids in short term in plants breeding compared to seed culture. However, anther culture method in generating transgenic rice still has low productivity of plant regeneration in some genotypes of Japonica rice. Therefore, we examined the efficiency of callus induction and transformation with three different cultivars of Japonica rice, Haiami, Ungwang and Dongjin. In this study, our results showed that Haiami is the best genotype among three cultivars of Japonica rice as callus inducing material in anther culture to produce transgenic rice plants conferring resistance to insects.

Drought and salinity are the major abiotic stresses which are being continued to hamper the ecosystem and agriculture of the affected region. Plant species have adaptations to enhance their ability to tolerate stresses through physiological adjustment. Therefore, substantial amount of research are ongoing to provide insights about those mechanisms which enlighten the stress tolerance in plant. In this study, several rice cultivars were collected from the different parts of the world and ion accumulation experiments were conducted to select the best stress tolerant cultivar in drought and salt stress environment. For stress treatment, five rice cultivars were subjected to salt (200 mM NaCl) and drought (200 mM Mannitol) for 72h. Later Na+, Ca++, K+ concentrations in shoot and root samples were examined at different time interval. In both drought and salt stress, rice cultivar C201 (collected for uzbekistan) showed the lowest levels of Na+ ion and Na+: K+ ratio compared to other cultivars. It was significant parallel observation with pokkali (known salt tolerant cultivar). In this preliminary study, it was observed the C201 had more stress tolerant in terms of ion accumulation; however detail physiological studies are required to strengthen the idea regarding the best stress tolerant physiotype.
