To analyze the seismic reliability of concrete rectangular liquid storage structures (CRLSSs), assuming that the wall thickness and internal liquid depth of CRLSSs are random variables, calculation models of CRLSSs are established by using the Monte Carlo finite element method (FEM). The principal stresses of the over-ground and buried CRLSSs are calculated under three rare fortification intensities, and the failure probabilities of CRLSSs are obtained. The results show that the seismic reliability increases with the increase of wall thickness, whereas it decreases with the increase of liquid depth. Between the two random factors, the seismic reliability of CRLSSs is more sensitive to the change in wall thickness. Compared with the over-ground CRLSS, the buried CRLSS has better reliability.

Due to the increasing demand for convenience and simplicity, Home Meal Replacement (HMR) has become a key trend in the food service industry. This study researched the current consumer trend and analyzed the national and international HMR product trend, aiming to find useful insights for the field. Results showed that in order to expand the HMR market demand, it is possible to consider diversifying the product category by making customized premium products, such as products for the elderly, infants, patients, and sports players, or products with enhanced nutritional fortification. From the industrial aspect, centralization through Central Kitchen (CK) and implementation of the scientific and advanced ISO and HACCP system are necessary. Lastly, to develop high value-added HMR products, it is deemed essential to utilize the so-called 'food tech', the technology which integrates core technologies of the fourth industrial revolution into the food industry.

The NHIS provides free or highly subsidized healthcare to all people by providing financial fortification. However, the financial sustainability of the scheme is threatened by numerous factors. Therefore, this work sought to provide a solution to process claims intelligently. The provided Petri net model demonstrated successful data flow among the various participant. For efficiency, scalability, and performance two main subsystems were modelled and integrated - data input and claims processing subsystems. We provided smart claims processing algorithm that has a simple and efficient error detection method. The complexity of the main algorithm is good but that of the error detection is excellent when compared to literature. Performance indicates that the model output is reachable from input and the token delivery rate is promising.

Nonlinear forced vibration behaviors of sandwich plates having graphene platelets (GPL) based face sheets have been researched in this article. Possessing low weight together with low stiffness, square honeycomb cores are mostly constructed by aluminum. Herein, the square shaped core has been fortified by two skins of GPL-based type in such a way that the skins have uniform and linearly graded GPL dispersions. The square shaped core has the effective material specification according to the relative density concept. The whole formulation has been represented based upon classical plate theory (CPT) while harmonic balance approach is applied for solving the problem and plotting the amplitude-frequency curves. The forced vibration behaviors of such plates are influenced by square-shaped core and the relative density, skin's height and GPL fortification.

This paper aims to emphasize the necessity of beginning and developing judicial politics in Korea. Law is constitutive of politics, and judicial politics is vital in understanding how politics is influenced by law. Disappointingly, social science in Korea has not recognized the importance of judicial politics. Judicial branch in Korea does not have the capacity to constrain the executive or other government agencies governed by elected officials. The rule of law does not work. Judicial politics has not yet been introduced in Korea, despite its enormous importance in shaping political economy. The rule of law and courts are believed to be the institutional foundation for economic growth. Law embodied in "no one is above the law" is recognized to provide fairness and stability with a democracy. Little attention to judicial politics results in leaving behind a missing link in a polity. The fortification of the rule of law is necessary to make democracy consolidated in Korea, as shown in impeachment of former president Park Geunhae. A new scholarship in Korea on judicial politics is in need to discuss what conditions under which the rule of law is possible and how to make it sustainable.

To study the seismic vulnerability of the composite material structure of adobe and timber, we collected and statistically analysed empirical observation samples of 542,214,937 m² and 467,177 buildings that were significantly impacted during the 179 earthquakes that occurred in mainland China from 1976 to 2010. In multi-intensity regions, combined with numerical analysis and a probability model, a non-linear continuous regression model of the vulnerability, considering the empirical seismic damage area (number of buildings) and the ratio of seismic damage, was established. Moreover, a probability matrix model of the empirical seismic damage mean value was provided. Considering the coupling effect of the annual and seismic fortification factors, an empirical seismic vulnerability curve model was constructed in the multiple-intensity regions. A probability matrix model of the mean vulnerability index (MVI) was proposed, and was validated through the above-mentioned reconnaissance sample data. A matrix model of the MVI of the regions (19 provinces in mainland China) based on the parameter (MVI) was established.

Isolation technology has been proven effective in reducing the seismic response of superstructures, where most of the deformation is concentrated in the isolation layer. However, in cases of earthquakes with intensities surpassing the fortification level of the area, or severe near-fault earthquakes, the isolation layer may experience excessive deformation, resulting in damage to the isolation bearings or collisions with the retaining wall or surrounding buildings. In this study, a finite element model using ABAQUS is established and compared with experimental test results to deeply investigate the influence of limit devices on the isolation layer and its response to the superstructure. The findings reveal that a larger limiter stiffness and a smaller reserved gap can achieve a more effective limiting effect. Nevertheless, a smaller reserved gap and a larger limiter stiffness may result in increased response of the superstructure. Therefore, rational selection of the reserved gap and limiter stiffness is crucial to reduce the acceleration response.

In this paper, this writer looked into the initial law and fortification, which are two of the most important phonetic changes of Sino-Korean words. Pronunciation and inscription rules of Oriental Medical terminologies have also been studied. Moreover, several problems of meaningful rendering of Oriental Medical Chinese terminologies into Korean have been looked into. As a result, the following conclusions could be drawn. 1. The initial law only applies to Sino-Korean words that consist of more than one syllable. It does not apply to words borrowed from foreign languages. Especially, compound words like Jang-ssi-yu-gyeong(張氏類經) or Im-sin-yuk-hyeol(姙娠衄血) consist of already existing words such as Jang-ssi(張氏), Yu-gyeong(類經), Im-sin(姙娠), and Yuk-hyeol(衄血), and thus the initial law applies to these words. They are inscribed and pronounced 'Jang-ssi-yu-gyeong' and 'Im-sin-yuk-hyeol'. 2. Fortification of Sino-Korean words can be applied variously according to the structure and meaning of the words. Words such as '科', '格', '氣', '法', '病', '症', and '證' are often fortified and at the same time used frequently in Oriental Medicine. Also, many other words are derived from these words. However, there has not been a scholastic consent among the Oriental Medical society as to in which circumstances these words will be fortified. Therefore, a standardization process to stipulate the pronunciation of Oriental Medical terminologies is necessary. 3. Meaningful rendering of Oriental Medical Chinese terminologies into Korean also needs scholastic investigation. Especially, the word 兪 should be meaningfully rendered and pronounced 'su' just like the words 輸 and 腧, but is wrongly pronounced 'yu'. Other than this, the words 井滎兪經合, 秦艽, 膻中, 共振丹, 成無已, and 麗澤通氣湯 should respectively be pronounced 'jeong-hyeong-su-gyeong-hap', 'jin-gyo', 'dan-jung', 'gong-sin-dan', 'Seong-mu-yi', and 'Yi-taek-tong-gi-tang'. Moreover, there are four pronunciations to the word 梴 of 李梴. This should also be standardized. This writer proposes that in the future, correct meaningful rendering of Chinese terminologies into Korean and phonetic signs be inscribed in dictionaries regarding Oriental Medical terminologies.

The prevalence of iron deficiency in later infancy and the toddler years(25% to 40% at 1 year of age) has not decreased remarkably , except in Western countries. The purpose of this study was to 1) determine the relationship between current feeding practices and iron status, and 2) assess compliance to infant feeding instructions. Two groupsof infants were examined. The first group of 302 infants aged 6 to 24months was seen at a well baby clinic while the second group of 135 infants of the same age group was assessed by venipuncture. Cutoff values for laboratory tests were as follows ; hemoglobin<11g/dL, mean corpuscular volume (MCV) <72fl ; red cell distribution width(RDW)>15% ; serum ferritin level<10ng/ml ; and transferrin saturation (serum iron(TIBC)<10%. The diagnosis of iron deficiency anemia (IDA) was made when a low hemoglobin level was associated with either low ferritin orlow transferrin saturation . Of the 302 children brought to the well baby clinic , 12.3%(n=37) were found to have anemia (hemoglobin<11.0/dL). In terms of children grouped according to feeding practices, it was found that children with anemial comprised 32.0% (24/75) of the prolonged breast-fed group (Group A), significantly more than the 4.0%(7/176) of the artificial milk feeding group(Group B). and 3.9%(2/51) of the switched from breast milk to iron -fortified weaning foods group(Group C).Among the 107 children with IDA , iron deficiency in 105 children(98.1%) was suggested by their dietary histories ; exclusive or prolonged breast-feeding for more than 6 months without iron fortification in 98 infants ; cow's milk consumption> 500ml/day without iron fortification during infancy(n=12), or >800ml without iron-fortified foods after infancy(n=15) ; and the use of unfortified forumula or unbalanced diets, mainly limited to rice gruel. Despite the relatively high (79.6%) motivation on the part of the infants mothers and supervison by professional personnel, the poor results in the infants receiving iron fortified foods were due to poor compliance(85.75). Among the mothers of 98 IDA patients who were contacted by telephone , it was revealed that 29% did not give the oral iron preparation for more than 2 months. Furthermore, negligence or disregard by the parents occurred in 14% of the case , discontinuance of the oral iron preparation by the parents due to side effects occurred in 6%, and the children's refusal or poor oral intake and no further trial occurred in 6%. The dietary history of a large group of infants was highly predictive of their risk for anemia . Continued consumption of breast milk until the age of 1 year is not warranted unless iron-fortified foods are given concomitantly. Because there is a problem with compliance, more successful and safe strategies for preventing iron deficiency woold included dual coverage in the from of therapeutic iron supplementation as well use of iron-fortified foods for teddlers who are at risk of iron deficiency.
