Monthly variations in aneurysmal subarachnoid hemorrhage incidence and mortality: Correlation with weather and pollution

PLoS ONE (2017)

Myung‐Hoon Han Jinhee Kim Kyu-Sun Choi Choong Hyun Kim Jae Min Kim

Although the effect of weather and air pollution on the occurrence of subarachnoid hemorrhage (SAH) has been investigated, results have remained inconsistent. The present study aimed to determine the seasonality of aneurysmal subarachnoid hemorrhage occurrence and mortality.We used the National Inpatient Sample database to evaluate the effect of meteorological factors and air pollutants on patients with subarachnoid hemorrhage in Korea between 2011 and 2014. Monthly variations in SAH occurrence and mortality were analyzed using locally weighted scatter plot smoothing curves. Multivariate Poisson generalized linear regression models were used to evaluate potential independent meteorological and pollutant variables associated with SAH occurrence and mortality.In total, 21,407 patients who underwent clip or coil treatment owing to aneurysmal SAH in Korea from January 1, 2011, to December 31, 2014, were included. The crude incidence rate of SAH in Korea was 10.5 per 100,000 people per year. An approximately 0.5% lower risk of SAH was observed per 1°C increase in mean monthly temperature (relative risk, 0.995; 95% confidence interval [CI], 0.992-0.997; p < 0.001), while an approximately 2.3% higher risk of SAH was observed per 1°C increase in mean monthly diurnal temperature.We showed distinct patterns of seasonal and monthly variation in the occurrence and mortality of SAH. Our findings suggest that meteorological factors may play an important role in monthly variations in the occurrence of aneurysmal SAH.

Gonadal development and reproduction in the trumpet snail, Charonia sauliae

The Korean Journal of Malacology (2009)

Kyoung Ho Kang Jae Min Kim Seung Chun Seon Liang Liang Zhuo Hyun Jung Kim

This study devised and tested a histological staging system for gonadal development in the trumpet snail, Charonia sauliae, which was collected along the south coast of Jeju Island, South Korea. This paper details for the first time the gonadal development characteristics of C. sauliae. Ovary and testis development in C. sauliae can be roughly divided into five stages: growing, mature, spent, degenerative, and resting. The trumpet snail has multiple fecundation and fertilization [cycles?] during the spawning season for out-of-step gonadal development in high-temperature and low-salinity environments. Female trumpet snails tended to have larger shells and were more abundant than males (64.26% of all animals collected were female).

Effects of three microalgae, Tetraselmis suecica, Chaetoceros calcitrans, and Phaeodactylum tricornutum on larvae and spat growth in the trumpet shell Charonia sauliae

The Korean Journal of Malacology (2009)

Kyoung Ho Kang Seung Chun Seon Jae Min Kim Liang Liang Zhuo Hyun Jung Kim

The trumpet shell Charonia sauliae is an endangered and valuable species with potential for aquaculture. For artificial propagation of C. sauliae, the effects of three different food microalgae on the development, growth, and survival rate of the larvae and spat were investigated. For the larval feeding experiments, we utilized six microalgae species as food sources, namely Pavlova lutheri, Tetraselmis suecica, Nannochloris oculata, Isochrysis galbana, Chaetoceros calcitrans, and Phaeodactylum tricornutum; for the larval and spat growth and survival experiments, we utilized T. suecica, C. calcitrans, and P. tricornutum. The results showed that the temporal digestion index (TDI) for the veliger larvae was significantly different for C. sauliae fed the different microalgae species (P < 0.05), that the T. suecica, C. calcitrans, and P. tricornutum cultivars were better suited for larval consumption (P < 0.05), and that the growth and survival of the larvae and spat were significantly influenced by food type, specifically P. tricornutum (P < 0.05). Further research is needed to evaluate the effects of other microalgae species, different algal concentrations, and biochemical composition on the growth and survival of C. sauliae.

Impact of livestock industry on climate change: Case Study in South Korea — A review

Animal Bioscience (2023)

Sun Jin Hur Jae Min Kim Dong-Gyun Yim Yohan Yoon Sang‐Suk Lee

In recent years, there has been a growing argument attributing the primary cause of global climate change to livestock industry, which has led to the perception that the livestock industry is synonymous with greenhouse gas (GHG) emissions. However, a closer examination of the global GHG emission by sector reveals that the energy sector is responsible for the majority, accounting for 76.2% of the total, while agriculture contributes 11.9%. According to data from the Food and Agriculture Organization of the United Nations (FAO), the total GHG emissions associate with the livestock supply chain amount to 14.5%. Within this, emissions from direct sources, such as enteric fermentation and livestock manure treatment, which are not part of the front and rear industries, represent only 7%. Although it is true that the increase in meat consumption driven by global population growth and rising incomes, has contributed to higher methane (CH<sub>4</sub>) emissions resulting from enteric fermentation in ruminant animals, categorizing the livestock industry as the primary source of GHG emissions oversimplifies a complex issue and disregards objective data. Therefore, it may be a misleading to solely focus on the livestock sector without addressing the significant emissions from the energy sector, which is the largest contributor to GHG emissions. The top priority should be the objective and accurate measurement of GHG emissions, followed by the development and implementation of suitable reduction policies for each industrial sector with significant GHG emissions contributions.

The Effect of Broodstock Age on the Spawning Performance of Cultured Haliotis discus hannai

The Korean Journal of Malacology (2003)

Byoung-Hak Kim Kyoung Ho Kang Zhi Feng Zhang Jae Min Kim Jan Di Kim

The effect of broodstock age on the spawning performance of cultured abalone, Haliotis discus hannai, was assessed for five age groups (3, 4, 5, 6, 7 years old). Spawning performance of the five age groups was assessed in terms of the percentage of spawning abalone, eggs per spawning female, fertilization rates, hatch rates and attachment rates per spawning. The percentage of spawning abalone increased along with broodstock age, reached maximum in female groups of 5- and 6-year age (60%), and in male group of 6-year age (100%), subsequently decreased in 7-year age group. The number of eggs produced per spawning also increased with broodstock age, and the maximum was found in 6-year age. Although the number of spawned eggs for the oldest abalone declined, it still spawned much more eggs than 3, 4, and 5 years old females. The fertilization and hatch rates were obviously larger for 4-6 years old group than the younger and older abalones. The maxima were found in 5-year age group (96.0% and 84.5%), and the minimum were appeared in 7-year age group (79.3% and 58.2%). The attachment rate increased with broodstock age, reached maximum in 6-year age group (33.6%), although the increment gradually declined. The attachment rate for 7-year age group rapidly decreased (16.6%). These results suggested that broodstock age affected the spawning performance of H. discus hannai, which peaked between 5 and 6 years old, and broodstock should be bred during this period for hatchery production.

Greenhouse gas emission status in agriculture and livestock sectors of Korea: A mini review

Food and Life (2024)

Sun Jin Hur Jae Min Kim Dong-Gyun Yim Yohan Yoon Sang‐Suk Lee

The goal of achieving carbon neutrality is now a shared objective for humanity, with countries worldwide setting specific greenhouse gas (GHG) reduction targets by 2030. While initial concerns about global warming focused on fossil fuel use post-industrial revolution, perceptions shifted in the 2010s, highlighting the livestock industry as a significant contributor. However, a survey showed that the energy sector accounts for 71.2%, while agriculture contributes to only 11.9% of global GHG emissions, with only 7% of agricultural GHG coming from livestock. According to data from the Food and Agriculture Organization, the livestock sector accounts for 13.5% of the total GHG emissions. In Korea, GHG emissions from the agricultural sector are reported to be 2.9%, of which the livestock sector accounts for 1.3%. These findings underscore that the livestock industry is not the primary GHG emitter, emphasizing the need for intensive reduction efforts across high-emission industries like energy. Hence, setting accurate, data-based reduction targets and guidelines is crucial for effective GHG emissions mitigation.

Economic and Environmental Geology (2015)

Jae Min Kim Jung Chan Choi

본 연구의 목적은 예비조사 방법으로서 점검표를 이용하여 토질사면에 대한 산사태 취약도를 평가하고, 산사태 재해위험지도를 만드는 것이다. 국립재난안전연구원이 제안한 표들이 사면 안정성 평가에 적용되었으며, 이 표들은 토질사면에 대한 안정성 점검표로 구성되어 있다. 흙의 공학적 특성을 포함한 자료들은 부산 중심부의 황령산 지역에 대한 현지조사와 기존 연구를 통하여 획득되었다. 주제도를 만드는데 관련된 모든 자료는 ArcGIS 10.0을 이용하여 변환되었다. 이 방법을 사용한 결과 연구지역의 토질사면은 매우 안정-안정 영역에 분포되었으며, 중간 정도의 안정성 영역은 산의 말단부를 따라 부분적으로 분포한다. 산사태 위험도 지도의 결과는 산사태에 의한 피해를 방지하고, 적절한 토지이용계획을 수립하는 데 이용될 수 있을 것이다. The objective of this study is to evaluate landslide hazard susceptibility and produce the landslide hazard maps for soil slope using checklists as a preliminary investigation method. Tables, proposed by NDMI (National Disaster Management Institute), are applied for slope stability assessment, and are comprised of checklists on soil slopes. Database including engineering properties of soil is constructed through the field survey and results from previous studies for The Mt. Hwangryoeng area at center of Busan. All data related to creating the thematic maps was carried out using ArcGIS 10.0. Results from using this method indicated that soil slope are evaluated from very stable to stable. Moderate stability has been partially presented along the edge of mountain. Results from landslide hazard maps can be used to prevent damage from landslides and facilitate appropriate land use planning.
