Exposure to ultraviolet (UV) light is often associated with skin damage, sometimes very serious, and in recent times has received particular attention as a health risk. As a result, the proper use of sunscreen has long been recommended to protect against skin damage. The continued increase in the use of sunscreen may be linked to increased information about the risk of melanoma and non-melanoma skin cancer caused by prolonged exposure to ultraviolet rays. Natural and harmless materials that block and prevent UV light have emerged as essential household items in the field of skin beauty. New materials need to be considered and evaluated in relation to ultraviolet rays and their harmful effects. This study aims to explain the effect of UV exposure on human skin, the classification of sunscreens, the application of zeolite, nano clay, and LDH in sunscreen formulations, as well as the regulation of this service in various countries around the world.

Echeveria is a genus belonging to the Crassulaceae family that comprises approximately 170 species. It is a representative plant known as a succulent with economic potential in the floriculture industry. Echeveria plants are widely distributed in dry environments and endemic to Mexico. These plants have a rosette formation and varied leaf colors and shapes, which are characteristics of interest for landscaping, cut flowers, or interior decoration. Given their range of locations in different climates or indoor conditions, it is important to have an understanding and knowledge of their leaf morphology and anatomy and how they function to provide optimum care and management. Owing to high demand in horticultural markets, many breeders have crossed their desired species. However, this method has progressively increased the number of species without proper records of parents or other natural unintended crossings, creating phylogenetic problems and identification issues. The use and understanding of phenotypes, anatomical data, and/or research to aid in taxonomic issues and improve cultural management practices have been reviewed and discussed in this paper. In this review, we have provided a brief background of Echeveria species, focusing on the challenges and studies that have attempted to address these issues.

2023년 3월4일 저녁 9시30분 (뉴욕 현지 시각), 속개된 UN BBNJ 정부간회의에서 결국 UN BBNJ 협정 성안이 완성되었다. 본 논문에서는 국가관할권이원 전체를 규율하는 새로운 법문서로 채택될 UN BBNJ 협정이 디지털염기서열정보라는 최첨단 해양바이오 과학기술을 어떻게 규정하고 있는지 조문별로 검토해 보고, 향후 우리의 대응방안에 대해 제언하고자 한다. 이를 위해 UN BBNJ 협정 성안의 연혁과 그 규제 대상인 디지털염기서열정보의 논의 추이를 정리하고, UN BBNJ협정상 디지털염기서열정보 관련 조문을 하나씩 살펴보았다. 그리고 결론에서 향후 UN BBNJ 협정 이행을 위해서 우리가 고려해야 할 사항과 대응 방안을 국내 대응 방안과 국제 대응 방안으로 나누어 제언하였다. 국내 대응 방안으로는 국가관할권이원유래 디지털염기서열정보 통합관리제도 수립을 제언하였다. 그 이유는 현 UN BBNJ 협정 제10조가 국가관할권유래 디지털염기서열정보 통보·관리·보고·추적, 제도 수립을 규정하고 있기 때문이다. UN BBNJ 협정 제10조의 실효적 이행을 위해서는 현재 우리 국가관할권이원유래 디지털염기서열정보 관리상황에 대한 현황조사가 우선되어야 할 것으로 보인다. 국제 대응 방안으로는 첫째 제8조 적용조항 예외 선언 문제에 대한 결정, 둘째 UN BBNJ 정부간회의 당사국 총회 대응 전략 수립, 셋째 적극적인 생물다양성협약 당사국총회 참여를 제안하였다. 제8조에 대한 예외 선언을 하지 않는 경우, UN BBNJ 협정 발효이전에 생성된 디지털염기서열정보가 UN BBNJ 협정의 적용범위에 들어가기 때문에 현재 우리가 생성한 국가관할권이원 유래 디지털염기서열정보 현황에 따라 우리 산학연에 큰 부담이 될 수 있기 때문이다. 그리고 BBNJ 정부간회의 당사국총회와 생물다양성협약 당사국 총회에 대한 적극적이고 전략적인 대응을 제안한 이유는 UN BBNJ 협정이 당사국 총회에 많은 권능을 디지털염기서열정보의 관리 및 이익공유 분야에 부여하고 있기 때문이며, 생물다양성협약 당사국총회의 결정이 향후 UN BBNJ 협정에 큰 영향을 미칠 것으로 예측되기 때문이다. 특히 디지털염기서열정보의 범위와 정의가 아직 확정되지 않은 상황에서 생물다양성협약 당사국총회가 디지털염기서열정보의 범위와 정의에 대한 합의를 도출한다면, UN BBNJ 협정 역시 이를 준용할 가능성이 높으므로 UN BBNJ 협정 당사국총회와 생물다양성협약 당사국총회에 대한 통합적 대응이 필요하다.

『솟대 평론』은 2015년에 폐간된 『솟대 평론』의 뒤를 이어 2017년에 창간된 장애인 문학 저널이다. 따라서 ‘솟대 문학’이라는 장애인 문학의 기풍을 계승하 고 있다. 그러나 『솟대 평론』은 더욱 다양한 장르의 문학 양식과 장애인 주요 담론을 논의의 장으로 삼고 있다. 『솟대 평론』에 실린 총 6편의 구상솟대문학 상 수상 작품을 살펴보더라도 장애인 문학이 우수함을 알 수 있다. 장애인 문학 은 장애인만이 체험할 수밖에 없는 삶을 통해 인간 삶의 비극성, 삶에 대한 낙 관적 희망, 영적 통찰력 등을 보여주고 있다. 『솟대 평론』은 일반전문 잡지로 인식되나, 장르의 다양성과 장애인의 주체성을 고려해볼 때 특수성을 띤 특수 저널의 성격을 띠기도 한다. 『솟대 평론』은 일반전문 잡지와 특수 저널 사이의 어디엔가 위치한 특수성을 띤 저널이다.

In this review paper, the sources of odor, major odor compounds, and emission characteristics from livestock farms are summarized. The main sources of odor on livestock farms are barn facilities, manure storage facilities, manure composting facilities, and wastewater treatment facilities. High concentrations of odor are emitted during the manure removal process, and livestock odor tends to be the most severe in summer. There was a remarkable difference in odor intensity depending on the farm size and the cleaning condition, and odor intensity varied greatly depending on the weather parameters such as wind direction and speed. The concentrations of ammonia and hydrogen sulfide were high among the odor compounds emitted from livestock farms, and these compounds also contributed to odor intensity. The odor intensity in poultry and swine farms was higher than in cattle farms. Information on livestock odor emission is very useful for managing livestock odor complaints and designing odor abatement technologies.

The livestock industry continues to grow around the world, but livestock odor is becoming an environmental problem that is difficult to solve. In this review paper, the current status of the domestic livestock industry, livestock odor complaints, mediation cases involving environmental disputes related to livestock odor, livestock odor management policies and standards, livestock odor sources, major odor compounds, and emission characteristics are summarized. Domestic meat supply and meat consumption per capita are increasing, and livestock farms are becoming large-scale and intensive. Livestock odor complaints increased 4.5 times over the last five years (2014-2019), and its proportion to total odor complaints was 19%-30%. Livestock facilities larger than a certain size are classified as odor emission facilities and are managed based on the Odor Prevention Act. The information presented in this paper can be used to establish strategies to promote the sustainable development of the livestock industry while resolving air quality deterioration and public health problems caused by odor emissions from livestock farms.

This study aims to promote the necessity for future research from the perspective of the indoor environment by analyzing the trend of domestic COVID-19 confirmed cases and examining previous quantitative research cases. The limitations of the qualitative management plan were identified by analyzing the trend of confirmed cases and deaths in Korea and the trend before and after the implementation of 'social distancing' and 'step-by-step daily recovery', which are actually being applied. The trend of initial and follow-up measures for the outbreak of infectious diseases in Korea is judged to be a case where the importance of qualitative and quantitative management should be confirmed to prepare absolute quarantine measures. The results suggest that examining previous research cases and preparing through advanced research for effective application.

Background: Despite fall prevention strategies suggested by researchers, falls are still a major health concern in older adults. Understanding factors that differentiate successful versus unsuccessful balance recovery may help improve the prevention strategies. Objects: The purpose of this review was to identify biomechanical factors that differentiate successful versus unsuccessful balance recovery in the event of a fall. Methods: The literature was searched through Google Scholar and PubMed. The following keywords were used: ‘falls,‘ ‘protective response,‘ ‘protective strategy,’ ‘automated postural response,’ ‘slips,’ ‘trips,’ ‘stepping strategy,‘ ‘muscle activity,’ ‘balance recovery,‘ ‘successful balance recovery,‘ and ‘failed balance recovery.’ Results: A total of 64 articles were found and reviewed. Most of studies included in this review suggested that kinematics during a fall was important to recover balance successfully. To be successful, appropriate movements were required, which governed by several things depending on the direction and characteristics of the fall. Studies also suggested that lower limb muscle activity and joint moments were important for successful balance recovery. Other factors associated with successful balance recovery included fall direction, age, appropriate protective strategy, overall health, comorbidity, gait speed, sex and anticipation of the fall. Conclusion: This review discusses biomechanical factors related to successful versus unsuccessful balance recovery to help understand falls. Our review should help guide future research, or improve prevention strategies in the area of fall and injuries in older adults.
