Salinity stress is a major threat to plant growth and development, affecting crop yield and quality. This study investigated the effects of different salinity levels on photosynthetic responses and bulb growth of Lilium LA hybrid “‘Serrada’.” Plants were irrigated with 1 L of 0, 200, and 400 mM NaCl solutions every two weeks for 14 weeks in a greenhouse. At the end of the cultivation period, the substrate pH decreased, and electrical conductivity increased with increasing salinity. Regardless of salinity levels, the days to flowering and number of flowers were similar among treatments. In contrast, the flower width, plant height, number of leaves, and leaf area decreased with increasing NaCl concentrations. Although there were no differences in the photosystem II (PSII) operating efficiency and maximum quantum yield of PSII, net CO2 assimilation rates (An) and stomatal conductance (gs) were significantly reduced at 200 and 400 mM NaCl solutions compared to the control. At 400 mM NaCl solution, bulb diameter and weight significantly decreased at the end of the experiment. These results suggest that bulb growth inhibition could be attributed to limiting photosynthetic rate and stem growth. This finding suggests that salinity mitigation is necessary to maintain plant growth and photosynthetic capacity in lily cultivation on salt-affected soils.

기존에는 생산되는 키틴과 키토산의 대부분이 게, 새우등 갑각류 껍질에서 유래하였다. 하지만 어업에 의존하 는 기존 갑각류 비해 친환경적이며 품질 유지에 이점을 가지는 곤충으로부터 유래한 키틴이 최근 주목 받기 시작 하며 연구가 활발해지고 있다. 이에 키토산이 남조류의 응집을 통해 녹조 제거 효과를 가지며 기존에 녹조를 억제하기 위해 널리 사용되던 살조제들이 독성을 띠어 환경에 악영향을 미치는 문제를 해결할 수 있다는 연구를 참고하여 매미 탈피각으로부터 추출한 키토산을 녹조 방제에 활용해 보고자 하였다. 매미 탈피각으로부터 키토 산을 추출하고 대표적인 녹조 원인종인 Microcystis aeruginosa 배양 후 추출한 키토산을 처리하여 녹조의 응집 효과를 관찰하였다. 본 연구에서 새로운 키토산 추출 원으로서 매미 탈피각의 가능성을 제시하였으며 이를 녹조 방제에 활용함으로써 버려지는 자원인 매미 탈피각의 활용 방안을 제시하였다.

Porous carbons are considered promising for CO2 capture due to their high-pressure capture performance, high chemical/ thermal stability, and low humidity sensitivity. But, their low-pressure capture performance, selectivity toward CO2 over N2, and adsorption kinetics need further improvement for practical applications. Herein, we report a novel dual-templating strategy based on molten salts (LiBr/KBr) and hydrogen-bonded triazine molecules (melamine–cyanuric acid complex, MCA) to prepare high-performance porous carbon adsorbents for low-pressure CO2. The comprehensive investigations of pore structure, microstructure, and chemical structure, as well as their correlation with CO2 capture performance, reveal that the dual template plays the role of porogen for multi-hierarchical porous structure based on supermicro-/micro-/meso-/ macro-pores and reactant for high N/O insertion into the carbon framework. Furthermore, they exert a synergistic but independent effect on the carbonization procedure of glucose, avoiding the counter-balance between porous structure and hetero-atom insertion. This enables the preferred formation of pyrrolic N/carboxylic acid functional groups and supermicropores of ~ 0.8 nm, while retaining the micro-/meso-/macro-pores (> 1 nm) more than 60% of the total pore volume. As a result, the dual-templated porous carbon adsorbent (MG-Br-600) simultaneously achieves a high CO2 capture capacity of 3.95 mmol g− 1 at 850 Torr and 0 °C, a CO2/ N2 (15:85) selectivity factor of 31 at 0 °C, and a high intra-particle diffusivity of 0.23 mmol g− 1 min− 0.5 without performance degradation over repeated use. With the molecular scale structure tunability and the large-scale production capability, the dual-templating strategy will offer versatile tools for designing high-performance carbon-based adsorbents for CO2 capture.

Non-destructive estimation of leaf area is a more efficient and convenient method than leaf excision. Thus, several models predicting leaf area have been developed for various horticultural crops. However, there are limited studies on estimating the leaf area of strawberry plants. In this study, we predicted the leaf areas via nonlinear regression analysis using the leaf lengths and widths of three-compound leaves in five domestic strawberry cultivars (‘Arihyang’, ‘Jukhyang’, ‘Keumsil’, ‘Maehyang’, and ‘Seollhyang’). The coefficient of determination (R2) between the actual and estimated leaf areas varied from 0.923 to 0.973. The R2 value varied for each cultivar; thus, leaf area estimation models must be developed for each cultivar. The leaf areas of the three cultivars ‘Jukhyang’, ‘Seolhyang’, and ‘Maehyang’ could be non-destructively predicted using the model developed in this study, as they had R2 values over 0.96. The cultivars ‘Arihyang’ and ‘Geumsil’ had slightly low R2 values, 0.938 and 0.923, respectively. The leaf area estimation model for each cultivar was coded in Python and is provided in this manuscript. The estimation models developed in this study could be used extensively in other strawberry-related studies.

Colorectal cancer causes the most cancer-associated death worldwide, having a high cancer incidence. Pectin is a complex polysaccharide present in various fruits, emerging as an anti-carcinogenic candidate. Although pectin has a suppressive capacity for colon carcinogenesis, the effect of reactive oxygen species (ROS) generation and colonic aberrant foci formation in the colon carcinogenesis mouse model remains unclear. Therefore, this study investigates the regulatory effect of pectin supplementation on colon carcinogenesis induced by azoxymethane (AOM) and dextran sodium sulfate (DSS) in mice. In an animal experiment, thirty male institute for cancer research (ICR) mice were divided into two experimental groups; AOM/DSS (control group) and AOM/DSS + pectin (5% in drinking water). Furthermore, the number of aberrant crypt foci (ACF) and aberrant crypt (AC) on colonic mucosa were counted, and thiobarbituric acid-reactive substances (TBARS) assay was performed to estimate lipid peroxidation in feces. Pectin treatment significantly decreased the number of ACF and AC per colon compared with the control. Additionally, fecal TBARS level in the pectin group was significantly lower than those in the control group. Conclusively, these findings indicate that pectin-inhibited hyperplastic alteration and oxidative stress suppress colitis-associated colon carcinogenesis.

In weapon assignment studies to defend against threats such as ballistic missiles and long range artillery, threat assessment was partially lacking in analysis of various threat attributes, and considering the threat characteristics of warheads, which are difficult to judge in the early flight stages, it is very important to apply more reliable optimal solutions than approximate solution using LP model, Meta heuristics Genetic Algorithm, Tabu search and Particle swarm optimization etc. Our studies suggest Generic Rule based threat evaluation and weapon assignment algorithm in the basis of various attributes of threats. First job of studies analyzes information on Various attributes such as the type of target, Flight trajectory and flight time, range and intercept altitude of the intercept system, etc. Second job of studies propose Rule based threat evaluation and weapon assignment algorithm were applied to obtain a more reliable solution by reflection the importance of the interception system. It analyzes ballistic missiles and long-range artillery was assigned to multiple intercept system by real time threat assessment reflecting various threat information. The results of this study are provided reliable solution for Weapon Assignment problem as well as considered to be applicable to establishing a missile and long range artillery defense system.

The present study aimed to investigate rapid weight loss (RWL) and consequent physical and psychological challenges among judo athletes at the national athlete training center in 2017. The following results were obtained. Judo athletes used weight loss methods such as “gradually reduce meal portion,” “skip meals,” “limit water intake,” “wear sweat suit for training,” and “use sauna,” and had physical and mental distress from such unhealthy weight management practices. Information about weight loss was obtained from “colleagues or senior athletes,” “Internet,” and “head coach or coach,” and not experts such as nutritionists or physicians. Thus, athletes are recommended to employ healthy weight control methods based on advice from experts, such as nutritionists and physicians

The aim of the study was to investigate the effects of incentive spirometry and Ujjayi breathing technique on the pulmonary function of smokers. Subjects were individuals who had a smoking habit of at least a year. Subjects were randomly divided into 3 groups: the incentive spirometry group (n=8), Ujjayi breathing technique (n=9), and a group applying both incentive spirometry as well as Ujjayi breathing technique (n=8). Each intervention was performed twice a day, 5 times a week, for a total of 8 weeks whereupon the change in pulmonary function was evaluated. A spirometer was used to measure FVC, FEV1, and FEV1/FVC. The survey used for this study included the Fagerström Test of Nicotine Dependence (FTND) and the Shortness of Breath Questionnaire (SOBQ). Study results for the comparison within groups showed that in the group that performed both the incentive spirometry and Ujjayi breathing technique, FEV1 improved with statistical significance (p<.05). Furthermore, within this comparison the FEV1/FVC improved with statistical significance. Comparison amongst the groups showed no statistically significant differences in all areas. Following, to effectively increase pulmonary function in young adult smokers, both incentive spirometry and Ujjayi breathing technique should be employed together.

The purpose of this study was to investigate the effects of core muscle training on balance ability. Forty subjects in their 20s participated in a 6 week core muscle training program. Balance ability before and after the intervention were assessed and analyzed using the Romberg test, which was conducted on the floor, pedalo, and balancefit. The differences between the measurement methods of balance ability using varied platforms was also compared and analyzed. After the 6-week core exercise training program, the training group represented statistically significant increases in all 3 methods for static balance ability. In the control group, all 3 methods represented no statistically significant increases. Upon comparing the different methods of the Romberg test, there were no notable differences between conducting the test on varying platforms for both groups. This study suggests that the core muscle exercise training program increased the balance ability.

The aim of this study was to observe the effects of kinesiotaping and joint mobilization on the metatarsophalangeal joint angle and pain in hallux valgus patients Twenty-one female hallux valgus patients in their 20s were divided into two groups, a Kinesiotaping group (KT, n=10) and another group with the addition of joint mobilization (KTJM, n=11). After undergoing 6 weeks of intervention, the change in the metatarsophalangeal joint and pain were measured. Metatarsophalangeal joint angle was significantly increased both the KT and the KTMJ group after intervention. In the change of pain, both the KT and KTJM groups on an individual basis also experienced a significant decrease in pain, though comparison between the two groups failed to represent a significant difference. These findings suggest that Kinesiotatping and joint mobilization increased the joint angle and reduced pain.

The purpose of this study was to compare the effects of respiratory exercise on cardiopulmonary function and muscle activity of rectus abdominis in smokers and non-smokers with elderly people. All the participants were older than 65 years, and twenty non-smokers, and twenty smokers participated. Non-smokers and smokers were randomly divined into 10 feedback breathing exercises (FBE) and a balloonblowing exercise (BBE) group. The FBE and the BBE were performed three times a week for four weeks. Forced vital capacity (FVC), forced expiratory volume at one second (FEV1), forced expiratory volume at one second/forced vital capacity (FEV1/FVC), peak expiratory flow (PEF), and vital capacity (VC) were measured as pulmonary function. EMG was used to measure the activity of the rectus abdominis. In the FBE and BBE groups, FEV1 was significantly lower in non-smokers compared to smokers at two and four weeks (p<.05), FEV1/FVC, PEF and VC were significantly lower in non-smokers compared to smokers to pre-test, two weeks, four weeks and six weeks (p<.05). Muscle activity of rectus abdominis was significantly difference in the BBE group at pre-test, two weeks, four weeks, and six weeks (p<.05). These results suggest that respiratory exercise was effective in improving pulmonary function and rectus muscle activity.

This study used both kinesiotaping and extracorporeal shock wave therapy on patients diagnosed with frozen shoulder - a common musculoskeletal disorder in adults - in order to observe the effects on the joint range of motion. 21 adult(male 12, female 9) were selected and distributed into randomized groups. One group received kinesiotaping (n=10) and the other group received kinesiotaping together with extracorporeal shockwave therapy (n=11). After a 6 week duration of receiving kinesiotaping and extracorporeal shockwave therapy, changes in the joint range of motion in the patients were observed. Post-treatment of frozen shoulder, the changes in abduction within the shoulder joint were as follows: in both groups there was a noticeable increase in the joint range of motion (p<.05). Post-treatment of frozen shoulder, the changes in external rotation within the shoulder joint were as follows: both groups showed a significant increase in the joint range of motion (p<.05). The result of suggest that, it can be inferred that both the extracorporeal shockwave therapy and kinesiotaping are effective in increasing the joint range of motion in patients with frozen shoulder.

The purpose of this study was to determine the effects of music therapy and ball exercise on women experiencing menstrual discomforts, thereby identifying the validity of these methods as interventions against menstrual discomforts, with a particular goal of presenting basic data for clinical use. Twenty university students in their 20s were assigned to two therapy groups in a sequence via simple random sampling; ten subjects attended a ball exercise combined with music therapy group and the other ten subjects attended a music therapy group. Ball exercises were conducted 3 times per week for a total of 12 times, starting from 3 weeks before the expected first day of the menstrual period and ending on the last day of the menstrual period. Similarly, the subjects participated in music therapy by listening to music for 35 minutes per session and 3 sessions per week, starting from 3 weeks before the expected first day of the menstrual period and ending on the last day of the menstrual period. Five out of six categories of menstrual discomforts were significantly decreased in both music therapy and ball exercise, the exception being changes in the autonomic nervous system, while those in the music therapy group showed a significant difference only in the category of behavioral changes. The results of the present study demonstrate that the ball exercise combined with music therapy more effective in improving menstrual discomforts than the music therapy group.

A powder injection molding process is developed and optimized for piezoelectric PAN-PZT ceramics. Torque rheometer experiments are conducted to determine the optimal solids loading, and the rheological property of the feedstock is evaluated using a capillary rheometer. Appropriate debinding conditions are chosen using a thermal gravity analyzer, and the debound specimens are sintered using sintering conditions determined in a preliminary investigation. Piezoelectric performance measures, including the piezoelectric charge constant and dielectric constant, are measured to verify the developed process. The average values of the measured piezoelectric charge constant and dielectric constant are 455 pC/N and 1904, respectively. Powder injection molded piezoelectric ceramics produced by the optimized process show adequate piezoelectric performance compared to press-sintered piezoelectric ceramics.
