  • It has become important to explore alternative feed ingredients to reduce feed costs, which are burdensome for livestock production. In addition, it is desirable to find efficient and functional alternative ingredients for traditional feed ingredients in pig diets, considering the stress and sensitivity of disease of pig. Rice is produced around the world like corn that is the typical energy source in pig diets. Although the nutritional quality varies depending on the degree of milling, rice, except whole grains (paddy rice), contains more starch than corn and its structure and granule size are easier to digest than corn. In addition, the fact that rice has fewer non-starch polysaccharides (NSP) and anti-nutritional factors (ANFs) is also effective in improving digestibility and various polyphenols in rice can help modulation of immune responses, which can be beneficial to the gastrointestinal environment and health of pig. Many studies have been conducted on rice focusing on things such as degree of milling, substitution rates of corn, granule size, and processing methods. Most results have shown that rice can be partially or completely used to replace corn in pig diets without negatively affecting pig growth and production. While further research should focus on the precise biological mechanisms at play, it was confirmed that the use of rice could reduce the use of antibiotics and pig removal and protect pigs from gastrointestinal diseases including diarrhea. From this point of view, rice can be evaluated as a valuable feed ingredient for swine diets.

  • Objective The management of psychological distress in patients with cancer is a major concern in clinical practice. In this paper, we discussed how to apply the controlling methods of Seong-Jeong (性情) and covetous desire (心慾) of Sasang constitutional medicine to patients with cancer. Methods We investigated the controlling methods of Seong-Jeong (性情) and covetous desire (心慾) through the literature of " Gyukchigo (格致藁)", "Donguisusebowon-Sasangchobongyun (東醫壽世保元 四象草本卷)", "Donguisusebowon (東醫壽世保元) and "Dongmuyougo (東武遺稿)", and presented the controlling methods of Seong-Jeong (性情) and covetous desire (心慾) for patients with cancer based on the clinical experience. Results We identified the equilibrium and harmony (中節) of sorrow-anger-joy-pleasure (喜怒哀樂) is the basis of treatment and suggested 'understanding of the others (知人)', 'understanding of the diseases (知病)' and 'knowing and acting (知行)' as methods to control of Seong-Jeong (性情) and covetous desire (心慾). The 'understanding of the others (知人)' and 'understanding of the diseases (知病)' could reduce the psychological distress. The 'knowing and acting (知行)' encourages the patients to overcome the covetous desire (心慾) and have a positive attitude to life and disease. Conclusion The controlling method of Seong-Jeong (性情) and covetous desire (心慾) of Sasang constitutional medicine could help cancer treatment controlling the psychological distress of patients with cancer, and could impact positively on the view of life and disease.

  • The Earth's surface deforms vertically in response to a variety of sources relating to lithospheric and sub-lithospheric processes, and distinguishing the continental mechanisms for vertical motions of the lithosphere remains a fundamental challenge in geosciences. A key prerequisite to the challenge is documentation of the temporal and spatial pattern of vertical motions in different tectonic settings. This study is aimed at elucidating the geodynamic factors that can contribute to vertical motions of the Earth's surface in intraplate continental settings including the Neogene uplift in the Korean peninsula based on numerous recent achievements in relevant fields. Ultimately, deciphering the interplay between the Earth's surface and the Earth's interior processes leads us to the notion of "the importance of geomorphic landscape" as a prism to view the dynamics of the Earth's inside.

  • Don DeLillo has shown considerable interest in terror, frequently depicting extreme dread of something terrible to happen, in his literary texts. Since more than three thousand innocent people in New York were killed by the 9-11 terrorist attack in 2001, the anticipation about what kind of fiction he would write as a New Yorker was high. DeLillo's novel Falling Man (2007) in fragmentary detail represents the scene of the terrorism from the perspective of Keith Neudecker, a lawyer who escapes the collapsing world trader center. Neudecker's post-traumatic stress disorder in the first chapter is followed by the free-associative portrayal of various impacts of the 9-11 terror on Neudecker's wife Lienne in the second chapter. The random mixture of the first person narratives from such diverse view-point characters as Neudecker's son Justin, relatives and friends, with dialogues and recollections yields a very close picture of the consequences of terrorism. Reading DeLillo's Falling Man in juxtaposition with a Japanese Canadian novel Obasan by Joy Kogawa, reminiscences of the maltreatment of Japanese Canadians during and after the second world war, surfaces the authorial intention of the two novels. They as trauma literature emerge to aim at curing the readers and proposing post-traumatic ethics. Laurie Vickroy's theory of trauma narrative and cure, E. Ann Kaplan's theory of trauma witness narrative and responsibility, and Emmanuel Levinas's theory of trauma memory and ethics offer theoretical grounds for the convincing analysis of the two texts.

  • The study aims to determine the factors associated with married working women's health-related quality of life (HRQOL) in terms of general, marital, work, and health characteristics. In view of this, data was gathered from a total of 2,060 married working women who participated in the 7th wave (2017-2018) of the Korean Longitudinal Survey of Women and Family (KLoWF), which was conducted by the Korean Women's Development Institute. The data was analyzed using SPSS 25.0. As a result of inputting the general characteristics, marital characteristics, working characteristics, and health characteristics of married women, family's economic status, diagnosed disease, perceived stress were found to have a significant effect on married working women's HRQOL. Based on the study results, educational programs and various policies to help married working women better manage their family-work conflict were proposed as a means to improve their HRQOL. This study is significant as it identified a wide range of factors that affect married working women's HRQOL and discussed health and welfare measures to improve it.

  • Background and objective: With increasing land use intensity in urban areas, apartment buildings have been recognized as a typical type of urban residence. In this study, the impacts of different views through a window on health-related responses were investigated using psychological and physiological parameters. Methods: Photos of three different types of views taken on low (2-12 m), middle (28-35 m), and high (over 54 m) floors of dense apartment building areas were used as visual stimuli. Twenty-two healthy adults participated in the indoor experiment. Semantic differential methods and profile of mood states were used as psychological tools. Autonomic nervous activity was evaluated using blood pressures, pulse rate and heart rate variability (HRV). Results: Analytic data showed different characteristics of psychological and physiological outcomes in three different apartment views. In the analysis of psychological parameters, significantly negative responses to the views on middle floors were found in the subscales of tension-anxiety and anger-hostility, compared to low floors. Significantly positive scores in the subscale of vigor were found on low floors with abundance of vegetation and high floors with a view of the sky. A significantly increased value of HF was found on low floors (2,294.96 ± 169.79), compared to the middle(1,553.45 ± 84.66) and high (1,523.02 ± 70.49) floors. Despite the high scores in openness and vigor, high floor views showed significantly higher LF/HF values (1.83 ± 0.09), the indicator of the sympathetic nervous system, than low (1.30 ± 0.07) and middle floor views (1.34 ± 0.06), which might be related to the unconscious fear of heights. Conclusion: Views from different heights in an apartment building can affect the psychological states of residents. Green space through the window may have a positive health outcome by reducing physiological stress.

  • This research was carried out to investigate seed germination and growth of the perennial plant Apocynum lancifolium under different NaCl concentrations, with a view for future cultivation on reclaimed land. Initial characterization revealed that the average length and weight of A. lancifolium seed pods was 133.6 mm and 0.23 g, respectively, and the thousand-grain weight was 0.59 g. Upon examining the effects of light on seed germination, we found germination to be 1.7% higher under light conditions (90%) than under dark conditions (88.3%). In terms of the response to salt stress, we found that 90% of seeds germinated in the 0.00%, 0.25%, and 0.50% salt treatment groups. Although salt treatment up to a concentration of 0.5% was found to have little effect on seed germination, the rate of germination decreased at higher concentrations and was completely inhibited in the 2% treatment. We also established that germination rates were higher in seeds sown in horticultural topsoil than in the coarse sandy soil found in the plant's natural habitats. Although the growth of A. lancifolium tends to decrease with an increase in salt concentration, we found that the stem thickness, fresh weight, and dry weight of A. lancifolium seedlings subjected to 0.25%-1.0% salt were comparable to those of the control seedling that were not exposed to salt. Furthermore, in contrast to those plants subjected to 2.0% salt, these plants continued to grow and remained viable.

  • Industrialized and modular construction is a growing construction technique that can transfer a large portion of the construction process to off-site fabrication yards. This method of construction often involves the fabrication, pre-assembly, and transportation of massive and long volumetric modules. The module weight keeps increasing as the modules become more complete (with infill) to minimize the work at the site and, as higher productivity can be achieved at the fabrication shop. Thus, a volumetric module delivery gets more challenging and risky. Despite its importance, past research paid relatively insufficient attention to the problem related to the lifting of heavy modules. This can be a complex and time-consuming problem with multiple lifting for transportation-and-installation operations both in fabrication yard and jobsite, and require complex crane operations (sometimes, more than one crane) due to crane load capacity and load balance/stability. This study investigates this problem by focusing on the structural perspective of lifting such long volumetric modules through simulation studies. Various scenarios of lifting a weighty module from the top using four lifting cables attached to crane hooks (either a single crane or double crane) are simulated in SAP software. The simulations account for various factors pertaining to structural indices, e.g., bending stress and deflection, to identify a proper method of module lifting from a structural point of view. The method can identify differences in structural indices allowing identification of structural efficiency and safety levels during lifting, which further allows the selection of the number of cranes and location of lifting points.

  • Prediction of damage caused by low-velocity impact in laminated composite plate is an important problem faced by designers using composites. Not only the inplane stresses but also the interlaminar normal and shear stresses playa role in estimating the damage caused. But it is well known that the conventional approach based on the homogenization has the limit in description of damage. The work reported here is an effort in getting better predictions of dynamic behavior and damage in composite plate using DNS approach. In the DNS model, we discretize the composite plates through separate modeling of fiber and matrix for the local microscopic analysis. In the view of microscopic mechanics with DNS model, interlaminar stress behaviors in the inside of composite materials are investigated and compared with the results of the homogenized model which has been used in the conventional approach to impact analysis. Also the multiscale model based on DNS concept is developed in order to enhance the effectiveness of impact analysis, and we present the results of multiscale analysis considering micro and macro structures simultaneously.

  • Austenitic stainless steels and Ni-base alloys are widely used as structural materials for major components and piping system in pressurized water reactors (PWRs). These austenitic alloys are known to be susceptible to environmental assisted cracking (EAC), such as environmentally-assisted fatigue (EAF) and primary water stress corrosion cracking (PWSCC) during long-term exposure to PWR primary water environment. In this paper, the current understanding on the phenomena and mechanisms of these EAC are briefly introduced using experimental results and literature review. The mechanisms for EAF and PWSCC for austenitic stainless steels and Ni-base alloys are discussed. Currently, austenitic stainless steels are known to be more susceptible to EAF, while less susceptible to PWSCC than Ni-base alloys. The possible explanations to such behaviors are proposed and discussed in view of the role of hydrogen and internal oxidation.
