  • Care of people with severe disabilities requires care throughout their life cycle compared to non-disabled families. For this reason, carers of severely handicapped families are highly likely to have negative feelings throughout the family as well as daily stress. Disabled families also have a high rate of experiencing difficulties between non-disabled children or married couples in life centered on the disabled. In particular, the rapid aging in Korea affects the lives of the elderly disabilities along with the aging of the caregivers. The study explored alternatives to realistic support through the past and present experiences of caregivers with disabilities through qualitative research methods, and derived hopes and expectations for the future as follows.First, after confirming the disability for infants and toddlers with disabilities, information about the support system or system is provided from the rating agency. Second, providing "customized care support" suitable for the type of disability or individual characteristics at the social, political, institutional, and economic levels. Third, the provision of programs for non-disabled children and the provision of healing programs only for families with disabilities or those with disabilities. Fourth, the provision of spaces and programs that provide rest and rest for adults with disabilities. Fifth, the application of a long-term care system for the elderly reflecting the aging age of the disabled and institutionalization of community care for the disabled. The research is meaningful in that it presents discussion points for improving the quality of life of adults and the elderly with disabilities.

  • In this study, a criteria for the SWAT model calibration method in SWAT-CUP which considers multi-site and multi-variable observations was presented. For its application, the SWAT model was simulated using long-term observed flow, soil moisture, and evapotranspiration data in Yongdam study watershed, investigating the hydrological runoff characteristics and water balance in the water cycle analysis. The model was calibrated with different parameter values for each sub-watershed in order to reflect the characteristics of multiple observations through one-by-one calibration, appropriate settings of model simulation run/iteration number (1,000 simulation runs in the first iteration and then 500 simulation runs for the following iterations), and executions of partial and all run in SWAT-CUP. The flow simulation results of watershed outlet point, ENS 0.85, R2 0.87, and PBIAS -7.6%, were compared with the analysis results (ENS 0.52, R2 0.54, and PBIAS -22.4%) applied in the other batch (i.e., non one-by-one) calibration approach and showed better performances of proposed method. From the simulation results of a total of 15 years, it was found that the total runoff (streamflow) and evapotranspiration rates from precipitation are 53 and 39%, and the ratio of surface runoff and baseflow (i.e., sum of lateral and return flow, and recharge deep aquifer) are 35 and 65%, respectively, in Yongdam watershed. In addition, the analytical amount of available water (i.e., water yield), including the total annual streamflow (daily average 21.8 m3/sec) is 6.96 billion m3 per year (about 540 to 900 mm for sub-watersheds).

  • This study focuses on the process of internalizing the perception of negative discrimination among elderly people who have experienced age discrimination. The grounded theory method was used to identify the age discrimination experienced by the elderly in their daily lives and to explore the consequences of such discrimination through self-ageism. According to the analysis results, the elderly respond not only to explicit discrimination but also to implicit discrimination. In this process, the stronger the pain of old age (poverty, disease, ignorance, and solitude) and the stronger the memory of failing to respond to discrimination, the higher the level of self-ageism. "Self-ageism" has internalized the negative image of the elderly, who have been discriminated against by age, resulting in disadvantages in terms of quality of life through various reject/separate/suspension actions in reality. In the presence of supportive resources such as health, institutional support, and caregivers, the elderly have room to overcome self-ageism through more active ways. However elderly people who cannot motivate themselves and they lack these resources, elderly are trapped in negative reflux caused by self-ageism and sustained a depressed and shrinking life. In this state, it is not easy to motivate themselves and make physical, cognitive, emotional and social responses. Therefore, in this analysis, we specifically noted two aspects, contextual conditions and interventional conditions, and proposed programs for synchronizing senior citizens and improving resiliency from a microscopic point of view, and argued for the need to develop systems such as supplementing welfare and health service systems related to the entire life cycle, expanding accessibility and 'age-integration' through 'Community Care', awareness improvement and anti-discrimination laws.

  • PURPOSE: Aging causes a decrease in muscle mass and a change in posture, which reduces motor function and makes it difficult to perform daily activities independently. As these factors are closely related to the deterioration of the quality of life, it is very important to prevent and manage negative changes in the musculoskeletal system. Forest healing is a nature therapy course that maintains and promotes health using various environmental factors in a forest. The purpose of this study was to identify the effects of the forest healing anti-aging programs on the physical health of the elderly. METHODS: Ten elderly people participated in this study, as part of a forest healing anti-aging program for two days. Functional fitness, muscle strength, gait function, and balance were evaluated before and after the program. RESULTS: The number of arm curls, chair stands, and steps in a 2-min walk significantly increased (p < .05). 8-feet up & go time was significantly decreased (p < .05). Biceps brachii, quadriceps femoris, and calf muscle strength were significantly increased (p < .05). Gait velocity and cadence were significantly increased (p < .05). Step length, stride length, step time, swing time, stance time, and cycle time were significantly decreased (p < .05). Reaching distance in the lateral directions was significantly increased (p < .05). CONCLUSION: The forest healing anti-aging program improves the physical health of the elderly.

  • Urbanization means the sudden increment of a population and the industrialization. The hydrologic water cycle causes many changes due to urbanization. Therefore, the affects that urbanization influences on the precipitation events were analyzed. But the precipitation events are very much influenced many meteorological and climatologically indices besides the effect of an urbanization. So, an analysis was performed by using precipitation data observed in many spots of the Korean peninsula. The analysis data are annual precipitation, the duration 1 daily maximum amount of precipitation, the rainy days, and 10 mm over the rainy days, and 80 mm. seasonal precipitation and seasonal rainy days. The analytical method classified 4 clusters in which the precipitation characteristic is similar through the cluster analysis. It compared and analyzed precipitation events of the urban and rural stations. Moreover, the representative rainfall stations were selected and the urban stations and rural stations were compared. In the analyzed result, the increment of the rainy days was conspicuous over 80mm in which it can cause the heavy rainfall. By using time precipitation data, the design precipitation was calculated. Rainfall events over probability precipitation on duration and return period were analyzed. The times in which it exceeds the probability precipitation in which the urban area is used for the hydrologic structure design in comparison with the rural area more was very much exposed to increase.

  • The purpose of this study is to examine changes in Korean middle school students' affective attitudes toward mathematics over the past 5 cycles of TIMSS. To this end, we first analyzed the changes in students' affective attitudes towards mathematics in five major countries, and then analyzed the changes in Korean students' affective attitudes toward mathematics by item. As a result of the study, there were positive changes in Korean students' interest, confidence, and value perception of mathematics during the recent 5 cycle of TIMSS. Korean male students' affective attitude toward mathematics is higher than that of female students, and the gender gap has been increasing recently. There was a large difference in the affective attitudes toward mathematics among Korean students, depending on their achievement level, and in particular, the affective attitudes toward mathematics of students at the lower achievement level remained significantly low. Item-level analysis revealed a decrease in Korean students' awareness of the necessity of mathematics in daily life. Based on these results, we discussed the implications for cultivating Korean students' affective attitudes. It is hoped that the results of this study will be meaningfully used as basic data for examining the performance of mathematics education in Korea and contribute to developing measures to foster students' positive attitudes toward mathematics.

  • In this study, we compare and analyze the performance of three inventory management policies for raw material inventory management in a Precast Concrete production plant: Fixed Order Quantity Policy (FOQP), Fixed Order Interval Policy (FOIP), and (s, S) Ordering Policy (sSOP). In order to make more realistic conclusion, we developed and utilized the ARENA simulation model, a performance evaluation tool that considers the variance of raw material demand and supply for the entire production process in a PC production plant using multiple raw materials. For the three policies, reorder point, order quantity, target level, and order interval parameters were initialized by using Economic Order Quantity (EOQ) model and then optimized through OptQuest. As a result of optimization, inventory management costs were reduced by an average of 97.28% compared to the EOQ model that does not consider the variance of demand and supply. After setting three influencing factors, Project Occurrence Cycle (POC), Raw Material Lead-time (RML), and Unit Stock-out Cost (USC), a performance evaluation was conducted for the three policies. As a result of evaluation, the inventory management costs of FOQP and sSOP, which determine order intervals by considering inventory levels by real-time or daily, were 30.6% and 27.9% lower than FOIP with fixed order intervals respectively. In addition, inventory management costs were affected by RML and USC factors excluding POC, but the differences were 2.17% and 2.09% respectively, which were not large due to the optimization of parameters for responding the variance of raw material demand and supply.

  • The war that broke out on October 7, 2023 is prolonging and expanding into the Middle East. Although the damage from war is increasing, humanitarian aid to the Gaza Strip has been halted due to UNRWA's deviant actions. Powerful countries have suspended support, and the UN is appealing for support for the Gaza Strip. All damage is borne by civilians in the Gaza Strip, especially women, children, and the elderly. Israel has selected an evacuation zone and evacuation route in the Gaza Strip and established a humanitarian aid route in the border area. However, Hamas's resistance in underground tunnels, using civilian-dense areas and civilian facilities such as hospitals and schools as shields, further amplified civilian casualties. This Israel-Hamas war requires the international community to approach it from a human security perspective. We must strengthen the UN's functions and roles to ensure that humanitarian supplies reach the field and humanitarian intervention forces ensure human dignity and basic rights. We must restore the credibility of the UN's role through the Israel-Hamas war. In addition, Korea should urge the introduction of humanitarian aid and goods, and provide humanitarian goods such as daily necessities and medicine. We must also prepare for deployment as a member of the UN peacekeeping force in the future. These activities will help Korea develop into a model country that fulfills its role as a 'global pivotal nation' and will have a virtuous cycle of international support in the event of a future crisis on the Korean Peninsula.

  • Multiple ovulation and embryo transfer (MOET) has the potential to increase the rates of genetic improvement in cattle. Thus this study was performed to investigate several factors influencing in vivo embryo production in Holstein cattle under field conditions. The donors were superovulated with Folltropin-V and $PGF_2{\alpha}$ combination method. From Day 10 onward, donors were superovulated by i.m., twice daily, administration of 400mg Folltropin-V given in a series of decreasing doses over a 4-day period: on the first day, 3.5ml; on the second day, 3.0ml; on the third day, 2.0ml; and on the fourth day, 1.5ml (20ml in total, equivalent to 400mg of NIH-FSH-P1). Estrus was induced by i.m. administration of 25mg prostaglandin $F_2{\alpha}$ on the sixth and seventh of FSH treatment. Estrus detection was performed twice daily beginning 24h after the first prostaglandin $F_2{\alpha}$ injection. Donor cows were artificially inseminated 12 and 24 h after first standing estrus with semen from a proven Holstein sire. Embryos used in this study were recovered Day 7.5 of the cycle (Day 0: first standing estrus). From 195 superovulated dairy cows, 2,104 eggs were recovered, of which 1,172 were classified as transferable embryos based on morphological evaluation of quality. The results are summarized as follows: 1. The numbers of recovered and transferable embryos did not significantly differ among the capacity of milk production that were < 10,000kg/305days (group 1), $10,000{\sim}12,000\;kg$/305days (group 2) or > 12,000kg/305 days (group 3) (p>0.05, Table 1). 2. No differences in the numbers of recovered and transferable embryos were found among the donor's postparient days (p>0.05, Table 2). 3. Also, the numbers of recovered and transferable embryos of each superovulation seasons did not significantly differ among the four groups (p>0.05, Table 3).

  • Analysis of a long cycle or a trend of time series data based on a long-term observation would require comparability between data observed in the past and the present. In the present study, we proposed an approach to ensure the compatibility among the instruments used for the long-term observation, which would allow to secure continuity of the data. An open-path gas analyzer (Model LI-7500, LI-COR, Inc., USA) has been used for eddy covariance flux measurement in the Gwangneung deciduous forest for more than 10 years. The open-path gas analyzer was replaced by an enclosed-path gas analyzer (Model EC155, Campbell Scientific, Inc., USA) in July 2015. Before completely replacing the gas analyzer, the carbon dioxide ($CO_2$) and latent heat fluxes were collected using both gas analyzers simultaneously during a five-month period from August to December in 2015. It was found that the $CO_2$ fluxes were not significantly different between the gas analyzers under the condition that the daily mean temperature was higher than $0^{\circ}C$. However, the $CO_2$ flux measured by the open-path gas analyzer was negatively biased (from positive sign, i.e., carbon source, to 0 or negative sign, i.e., carbon neutral or sink) due to the instrument surface heating under the condition that the daily mean temperature was lower than $0^{\circ}C$. Despite applying the frequency response correction associated with tube attenuation of water vapor, the latent heat flux measured by the enclosed-path gas analyzer was on average 9% smaller than that measured by the open-path gas analyzer, which resulted in >20% difference of the sums over the study period. These results indicated that application of the additional air density correction would be needed due to the instrument heat and analysis of the long-term observational flux data would be facilitated by understanding the underestimation tendency of latent heat flux measurements by an enclosed-path gas analyzer.
