Processed meat products play a vital role in our daily dietary intake due to their rich protein content and the inherent convenience they offer. However, they often contain synthetic additives and ingredients that may pose health risks when taken excessively. This review explores strategies to improve meat product quality, focusing on three key approaches: substituting synthetic additives, reducing the ingredients potentially harmful when overconsumed like salt and animal fat, and boosting nutritional value. To replace synthetic additives, natural sources like celery and beet powders, as well as atmospheric cold plasma treatment, have been considered. However, for phosphates, the use of organic alternatives is limited due to the low phosphate content in natural substances. Thus, dietary fiber has been used to replicate phosphate functions by enhancing water retention and emulsion stability in meat products. Reducing the excessive salt and animal fat has garnered attention. Plant polysaccharides interact with water, fat, and proteins, improving gel formation and water retention, and enabling the development of low-salt and low-fat products. Replacing saturated fats with vegetable oils is also an option, but it requires techniques like Pickering emulsion or encapsulation to maintain product quality. These strategies aim to reduce or replace synthetic additives and ingredients that can potentially harm health. Dietary fiber offers numerous health benefits, including gut health improvement, calorie reduction, and blood glucose and lipid level regulation. Natural plant extracts not only enhance oxidative stability but also reduce potential carcinogens as antioxidants. Controlling protein and lipid bioavailability is also considered, especially for specific consumer groups like infants, the elderly, and individuals engaged in physical training with dietary management. Future research should explore the full potential of dietary fiber, encompassing synthetic additive substitution, salt and animal fat reduction, and nutritional enhancement. Additionally, optimal sources and dosages of polysaccharides should be determined, considering their distinct properties in interactions with water, proteins, and fats. This holistic approach holds promise for improving meat product quality with minimal processing.

Televiewer is a logging tool capable of scanning the borehole wall. The tool uses a rotating acoustic beam generator that acts as both a transmitter and receiver. The beams are sent toward the wall. The amplitude of a returning signal from the wall has nearly a linear relationship with the reflection coefficient R of the borehole wall, when the wall is smooth. As R depends only on rock impedance for fixed water impedance, the amplitude is directly associated with mass density and seismic velocity of rock. Meanwhile, the amplitude can be further reduced by wall roughness that may be caused by drilling procedures, differences in rock hardness, because the rough surface can easily scatter the acoustic energy and sometimes the hole becomes elongated in all directions according to the degree of weathering. In this sense, the amplitude is related to the hardness of rocks. For convenience of analysis, the measured amplitude image(2-D data(azimuth ${\times}$ depth)) is converted, with an appropriate algorithm, to the 1-D data(depth), where the amplitude image values along a predetermined fracture signature(sinusoid) are summed up and averaged. The resulting values are subsequently scaled simply by a scalar factor that is possibly consistent with a known strength. This scaled Televiewer reflectivity is named, as a matter of convenience,“Televiewer rock strength”. This paper shows, based on abundant representative case studies from about 8 years of Televiewer surveys, that Televiewer rock strength might be regarded, on a continuous basis with depth, as a quitely robust indicator of rock classification and in most cases as an approximate uniaxial strength that is comparable to the rebound value from Schmidt hammer test.

With the globalization of Korean education and the rise in the average level of education, the number of international students in Korea, especially those from China, is rapidly increasing every year. This study aimed to provide the basic information for healthy dietary education by evaluating the dietary and nutritional status of Chinese students living in Gwangju province of Korea. Data from 468 subjects who met the study participation criteria and who had given their written informed consent were used for analysis. Of the total subjects, 52.4 and 80.1% were non-drinkers and non-smokers, respectively (p<0.01). It was observed that women were more stressed than men when they did not have convenient access to a Chinese food market near their place of residence (p=0.032). The subjects with a high cultural adaptation consumed kimbap (p<0.001) and pizza (p=0.017) more frequently than the subjects with a low cultural adaptation. An analysis of the nutrient quotient revealed that male scores were higher than those of the females with regard to water intake (p=0.035) and exercise level (p=0.021). For Chinese students living in Korea to maintain proper dietary habits, it is necessary to educate them on how to purchase convenience foods and improve their lifestyle, including limiting drinking and smoking. It is also necessary to develop emotional support programs for stress management and cultural adaptation.

In this paper, we analyze the existing ecovillages in order to establish a planned-ecovillage model to suggest improvement in direction of ecovillage planning; namely, efficiency of planning elements through analysis of changes in ecovillages. Changes to living environment require increased relaxation and convenience to ensure quality of life. Unlike general ecovillages, planned-ecovillages differ in their introduction of planning elements by autonomous decision-making through discussions and meetings among residents. In the village planning process, complex planning, community facilities, ecology-base facilities, water-resource utilization, and waste disposal can waver from initial planning, giving rise to realistic alternatives to village characteristics for those considering changes to space organization.
