  • The technical feasibility of removing cholesterol from milk fat by supercritical carbon dioxide $(SC-CO_2)$ extraction followed by adsorption on different adsorbents and of fractionating milk fat into different fatty acid composition at $40^{\circ}C/276$ bar was investigated. Cholesterol could be selectively removed from milk fat by adsorption on a typical commercial florisil with $SC-CO_2$ extraction. Lower weight ratio of milk fat feed to florisil showed higher reduction of cholesterol, but gave lower yield in the milk fat fractions. The effective capacity of florisil for removing cholesterol from milk fat was 2.0g/g, which is the ratio of the fat feed to the adsorbent for 89% cholesterol reduction with a fat yield of 57.5%. Fatty acid composition showed higher short-chain and lower unsaturated long-chain fatty acids in the extracted fractions. Milk fat fractionation method by supercritical fluid extraction in coupled with adsorption would appear suitable for removing undesirable ingredients such as cholesterol and for enriching short-chain fatty acids in the fractions.

  • The present study investigated the anti-obesity effects of Sparassis crispa (SC) on mice fed a high-fat (HF, 45 kcal% fat) diet. Mice were fed either a normal control diet and an HF diet or an HF diet supplemented with SC (1%, 3%, and 5%) for 12 weeks. The consumption of an HF diet compared to the NC group resulted in increases in body weight, the food efficiency ratio (FER), retroperitoneal and subcutaneous fat weights, cholesterol and triglyceride levels, fecal fat, and liver lipids. However, the administration of SC significantly decreased body weight gain, food intake, FER, cholesterol and triglyceride levels, and liver lipids in a dose-dependent manner. In particular, treatment with 5% SC significantly reduced the occurrence of fatty liver deposits and steatosis, which are associated with the increased adipocyte size in mice fed an HF diet. Therefore, these results suggested that dietary supplementation with SC exerts anti-obesity effects and could be used as a functional food to control obesity.

  • The purpose of this study was to find out the effect of a torrent control structure using customized tetrapods on the forest water quality conservation and management. The study was conducted in the Honggye valley located in Sanchung-gun, Gyungsangnam-do, and stream water quality was compared before and after construction of torrent control structure. After construction of the torrent control structure using customized tetrapods, pH of stream water didn't get out of the range of River water quality standard class I. After construction of the torrent control structure using customized tetrapods, Dissolved Oxygen concentration didn't change, and Electrical Conductivity measurements agreed well within the range of normal clean stream water quality. After construction of the torrent control structure using customized tetrapods, average of total amount of anion was 3.07/2.30~3.60 mg/L, being slightly greater than before construction. Stream water quality after construction of the torrent control structure was similar to before construction. Therefore, it was find out that the torrent control structure didn't affect stream water quality.

  • Recent aspects of terrorism varies in various ways according to means, targets, and regions. In particular, the 9/11 terrorist attacks in the United States in 2001 changed the paradigm of each country's terrorism, and the South Korea also participated in the enactment and enforcement of the Anti-Terrorism Act in 2016. Based on this, CBRN terrorism is included in general terrorism, and the National Police Agency plays the role of a control tower, and a system supported by related organizations such as the Ministry of Environment is being built and operated. However, restrictions were confirmed in the organizational system, manpower composition, and equipment and materials in operation in preparation for CBRN within the police. Based on the identified limitations, we proposed improvement plans to strengthen the capacity for CBRN terrorism: establishing a dedicated CBRN organization; creating research organization; and securing additional dedicated personnel. Based on this, as an improvement plan to strengthen the capability of CBRN, the establishment of an organization dedicated to CBRN and a research organization within the National Police Agency, and expansion of electronic equipment suitable for the characteristics of CBRN were proposed. It is expected that the police's on-site response capability system for CBRN terrorism will be strengthened via the proposed improvement measures to recover the various restrictions on the response to CBRN terrorism.

  • Asphalt-based waterproofing materials for bridge decks face issues such as softening or liquefaction of the material during the process of pouring hot asphalt concrete on top of the waterproofing layer. This leads to instability and reduced thickness of the waterproofing layer. To address these problems, new solutions beyond the existing materials, including the development and adoption of new materials, are required. Therefore, this study investigates the properties of MMA(Methyl Methacrylate) coating waterproofing material, which meets the basic physical properties for bridge deck waterproofing. We examined the overall quality standards in a system where the substrate concrete, waterproofing material, and paving layer are integrated. The study confirmed the applicability of MMA coating waterproofing material on bridge decks. The results indicate that a stable application of MMA coating waterproofing material for civil engineering structures' bridge decks can be achieved with a mix ratio of hard MMA resin : soft MMA resin : powder = 6 : 34 : 60. Additionally, when using emulsified asphalt with hardening characteristics for the adhesion between the dissimilar materials of MMA waterproofing and asphalt concrete, it is expected to meet the minimum quality standards of the Ministry of Land, Infrastructure, and Transport's 'Guidelines for Asphalt Concrete Pavement Construction (2021.07)'.

  • Objective : The purpose of this study is to examine the impact of maternal risk factors for adverse childhood experiences on children's emotional and physical abuse and neglect as well as parenting stress. Methods : This is a secondary data analysis study utilizing raw data from the 2017 National Survey of Child and Family Life Experiences. A total of 1,937 mothers with at least one adverse childhood experience were categorized into low-risk (1-3), moderate-risk (4-6), and high-risk (7 or more) groups to examine the differences in children's emotional and physical abuse and neglect and parenting stress and identify the influencing factors through regression analysis. Results : Maternal adverse childhood experiences were 50.4% in the low-risk group, 39.8% in the medium-risk group, and 9.7% in the high-risk group. Child emotional abuse was 45.0%, child physical abuse was 13.2%, child neglect was 3.5%, and parenting stress was 2.13 (±0.61) on average. Adverse childhood experiences were significantly more likely to be associated with emotional and physical abuse, neglect, and parenting stress in the medium- and high-risk groups than in the low-risk group. The regression analysis showed that the model explained 35% of child emotional abuse, 25% of child physical abuse, 19% of child neglect, and 16% of parenting stress. Conclusion : The higher the risk of adverse childhood experiences of parents, the more their children experience emotional abuse, physical abuse, child neglect, and parenting stress.

  • This study investigated the effects of Stevia rebaudian bertoni leaf extract on lipid profiles in C57BL/6J mice, as compared to stevioside. Fourty mice were divided into four groups: NC (normal diet and DW), HC (high fat diet and DW), HLSV (high fat diet and stevia leaf extract, 1 mL/kg/day), and HSS (high fat diet and stevioside, 1 mL/kg/day). Serum triglyceride concentrations were significantly lower in the HLSV and HSS groups than in the HC group. Epididymal fat pad weights were significantly lower in the HLSV and HSS groups than in the HC group. We also evaluated the serum and liver carnitine levels (NEC, AIAC, ASAC, TCNE) of all the groups. These results were supported by the mRNA expression of enzymes related to lipid metabolism (ACC, PPAR${\alpha}$, ACS, CPT-I) assessed by RT-PCR. Overall, the results show the antiobesity effects of stevia leaf extract as compared to stevioside in high fat diet induced obese mice.

  • Bangseonmun(訪仙門) is the attractive spots where Shinseon(神仙: Taoist hermit) ideas that makes Mt. Younju(瀛洲山) or the current Mt. Halla mystique has still remained and situated at Hancheon(漢川) Valley. Bangseonmun, which is known as 'Landscape Setting Here($L_{SH}$)' of Youngguchunhwa(瀛丘春花), which is one of ten famous spots in Youngjusipkyung(瀛洲十景), and Deulreonggui refer to 'the gate to the place where Shinseon is living.' It is described as the path to Mt. Youngju for Shinseon and the boundary between the mundane world and the world beyond the mundane. The old scholars at Mt. Halla entered the gate and met Shinseon, carving the word or picture of Bangseonmun, Whanseonmun, Wuseondae or Deungyounggu so as to structure the enchanting image on Bangseonmun. It is the poetic expression of the taste for the arts, breaking from the troublesome mundane world and riding the white deer to become the Shinseon, the desire for the ideal world in Taoism, and the identity of four famous scenic spots of Bangseonmun. Besides its enchanting meaning and the locational value of Bangseonmun, geological features of the valley and river and ecological value prove its unique value as a natural scenic beauty. Not to mention the locational identity and enchanting meaning of the poets carved in Meeaegak of Bangseonmun and the scenic view of 'Youngguchunhwa' as the subject of 10 famous scenes of Youngju, it is the place for communing with nature with the natural beauty of Bangseonmun Valley. As the cultural place for being together with Jeju people, it simultaneously shows the typical model as a scenic spot in our living. Viewing the scenic value and standard from the aspect of the Cultural Properties Protection Law, Bangseonmun Valley in Jeju must be the typical place and space that meet the requirements to become scenic sites.
