This study investigated various levels of sodium nitrite and probiotics (SNPro) combination as an alternative to zinc oxide on the growth performance, immune response, intestinal microflora, and morphology of weaned pigs. One hundred and ninety-two weaned pigs (Landrace×Yorkshire×Duroc) with an average body weight of 6.51±0.15 kg were randomly assigned to four treatments(n=6) on the basis of their initial body weight. Experimental period was divided into phase 1 and 2 (each 14 days). The dietary treatments were: 1) Basal diet (control), 2) SNPro1 (control+0.01% SNPro), 3) SNPro2 (control+0.02% SNPro), 4) SNPro3 (control+0.03% SNPro). The average daily gain when SNPro was added to the diet was 288, 309, 319, 324 g in phase 1, 355, 387, 410, 407 g in phase 2 and 321, 348, 364, 366 g in the overall. The concentration of interleukin-8 and interleukin-10 in serum when SNPro was added to the diet were 15, 13.5, 13, 12.8 ng/ml and 165, 162, 155, 145 ng/ml (p<0.05) but toll-like receptor 4 and immunoglobulin G levels in serum were no significantly different. The colonization of Escherichia coli in the ileum and Salmonella spp. in the caecum were significantly decreased as SNPro level increased (p<0.05). However, the population of Lactobacillus spp. did not differ among the groups. Although villus height and villus height to crypt depth ratio were not significantly affected by the treatments, crypt depth in the jejunum was 599, 586, 615, 599 ㎛ as SNPro level increased (p<0.05). In conclusion, SNPro had beneficial effects on growth performance, immune response, intestinal microflora and morphology weaned pigs. Therefore, SNPro not only can be considered as an alternative for the pharmacological level of zinc oxide in weaning pigs but also ideal dietary SNPro level was 0.02%.

This study was conducted to determine the effects of dietary protein level and supplementation of protease on growth performance, nutrient digestibility, gut microflora, intestinal morphology and fecal noxious gas emission in weanling pigs. A total of 240 weaned pigs (Landrace×Yorkshire×Duroc, 5.82±0.3 kg) were used during 4 weeks in 2 phases (days 0-14, phase 1; and days 15-28, phase 2) feeding program based on age and initial body weight. Pigs were allocated to 2×2 factorial arrangement, including 2 protein levels (HP, high protein; LP, low protein) and 2 protease levels (with or without protease). The average daily gain in the LP treatment (357 g/d) was increased rather than the HP treatment (339 g/d). A greater avarage daily gain was observed in dietary suppiemented protease treatment (358 vs 339 g/d). Average feed intake was greater in the LP treatment (544 g/d) rather than the HP treatment (530 g/d). A greater average daily feed intake was observed in dietary supplemented protease treatment (552 vs 523 g/d). Dry matter and crude protein digestibility were increased in dietary supplemented protease treatment (82.62% and 76.08%, respectively) rather than non-supplemented treatment (81.74% and 75.13%, respectively). Ileal Lactobacillus spp. count increased in dietary supplemented protease treatment (7.42 vs 7.32 log10CFU/g). Emission of H2S was decreased in the LP treatment (4.41 ppm) rather than HP treatment (4.78 ppm). Emission of NH3 was decreased in dietary supplemented protease treatment (10.43 ppm vs 11.76 ppm). In conclusion, the decrease of dietary protein level and supplementation of protease had beneficial effects on growth performance, nutrient digestibility, gut microflora, and noxious gas emission in weanling pigs.

It has been known that the global asteroseismic parameters as well as the stellar acoustic mode parameters vary with stellar magnetic activity. Some solar-like stars whose variations are thought to be induced by magnetic activity, however, show mode frequencies changing with dierent magnitude and phase unlike what is expected for the Sun. Therefore, it is of great importance to nd out whether expected relations are consistently manifested regardless of the phase of the stellar magnetic cycle, in the sense that observations are apt to cover a part of a complete cycle of stellar magnetic activity unless observations span several decades. Here, we explore whether the observed relations of the global seismic parameters hold good regardless of the phase of the stellar magnetic cycle, even if observations only cover a part of the stellar magnetic cycle. For this purpose, by analyzing photometric Sun-as-a-star data from 1996 to 2019 covering solar cycles 23 and 24, we compare correlations of the global asteroseismic parameters and magnetic proxies for four separate intervals of the solar cycle: solar minima 2 years, solar minima +4 years, solar maxima 2 years, and solar maxima +4 years. We have found that the photometric magnetic activity proxy, Sph, is an eective proxy for the solar magnetic activity regardless of the phase of the solar cycle. The amplitude of the mode envelope correlates negatively with the solar magnetic activity regardless of the phase of the solar cycle. However, relations between the central frequency of the envelope and the envelope width are vulnerable to the phase of the stellar magnetic cycle.

1991년 작품 Seeing Things를 『사물보기』 혹은 『환영보기』로, 1995년 노벨문학상 직후의 작품인 The Spirit Level을 『기포 수준기』 혹은 『영혼 측정』으로 변역할 수 있는 이유는 작가가 물질세계로부터 영혼세계로의 건너가기를 시도하고 있기 때문이다. 그런데 작가의 이 같은 시도는 부모님의 죽음이 가장 큰 동기였다고 생각한다. 작가는 그에게 영향을 끼친 부모와 지인들의 추억을 그들이 남긴 유품이나 업적과 함께 불멸의 유골 단지인 자신의 시에 보존시키려 한다. 아울러 『영혼 측정』의 많은 시들이 애가나 소네트 그리고 패스티쉬 형식의 헌정 시로 쓰인 점은 필자로 하여금 시인이 다가오 는 자신의 죽음을 준비하고 있다는 생각을 갖게 한다. 이 논문의 목적은 위의 추론을 이 시집 전체의 시를 읽어 증명할 뿐 아니라 수수께끼 같이 어려운 후기 시에 우리 말 번역과 해설을 시도하는 것이다.

In this study, the well-known non-destructive acoustic emission (AE) and electrical resistivity methods were employed to predict quantitative damage in the silo structure of the Wolsong Low and Intermediate Level Radioactive Waste Disposal Center (WLDC), Gyeongju, South Korea. Brazilian tensile test was conducted with a fully saturated specimen with a composition identical to that of the WLDC silo concrete. Bi-axial strain gauges, AE sensors, and electrodes were attached to the surface of the specimen to monitor changes. Both the AE hit and electrical resistance values helped in the anticipation of imminent specimen failure, which was further confirmed using a strain gauge. The quantitative damage (or damage variable) was defined according to the AE hits and electrical resistance and analyzed with stress ratio variations. Approximately 75% of the damage occurred when the stress ratio exceeded 0.5. Quantitative damage from AE hits and electrical resistance showed a good correlation (R = 0.988, RMSE = 0.044). This implies that AE and electrical resistivity can be complementarily used for damage assessment of the structure. In future, damage to dry and heated specimens will be examined using AE hits and electrical resistance, and the results will be compared with those from this study.

The purpose of this study is to investigate the effect of organizational safety and health management activities on safety and health performance by using the results of safety activity level evaluation of public organizations. To this end, a research model was established by using three fields as independent variables among the four areas of the safety activity level evaluation index: safety and health system, safety and health activity plan, and safety and health activity level, and the safety and health activity performance field as a dependent variable. Correlation analysis and regression analysis between major variables were performed. As a result of the correlation analysis, the safety and health activity performance had a significant positive (+) correlation with all of the safety and health system, safety and health activity plan, and safety and health activity level. The safety and health system had a significant positive (+) correlation with the safety and health activity plan and safety and health activity level, and the safety and health activity plan had a significant positive (+) correlation with the safety and health activity level. And as a result of the regression analysis, it was found that the organization’s safety and health system, safety and health activity plan, and safety and health activity level all had a significant positive (+) effect on safety and health activity performance.

본 논문은 역대 서론에 나타난 품평의 개념과 그 내면의 미학적 가치를 분석하는 것을 목적으로 하였다. 역대 서가 들은 서예를 품평하는데 격조, 자연, 대비 등의 방법을 통 해 간결한 언어와 생동감 있는 비유법을 많이 사용하며, 말로 전달하기 어려운 서예적 특징에 대해 깊이 묘사하고 있어 많은 여운을 남기고 있다. 품평의 등급에서는 먼저 ‘능품(能品)’은 필묵의 기교, 필법, 묵법, 결구, 장법 등이 정통함을 뜻하지만 ‘묘품(妙品)’ 보다 서가의 독창적인 개성미, 풍격미, 자연미, 정서미가 확연하지 않으며, ‘신품(神品)’과 비교해 ‘능품’의 서가는 천부 적인 재능이 부족하고 ‘일품(逸品)’에 비해 정취가 부족함을 뜻한다. ‘일품’과 ‘신품’은 모두 서예의 가장 높은 등급으로써 ‘일 (逸)’은 비교적 노장철학의 무위(無爲) 사상과 가까우며, ‘신(神)’은 비교적 공자철학의 중화사상에 가깝다. 기법 중시의 ‘신품’은 마음이 하고자한 바, 법도를 넘어서지 않는 것이고, 기법을 초월하는 ‘일품’은 자연의 묘와 같은 것이다. 따라서 ‘일품과 신품’은 모두 서예의 최고 형식이지만 ‘신품’이 ‘일품’ 보다 낮다고 보는 이유는, 인위적인 흔적이 그래도 존재하기 때문에 아래에 두고 평가한 것이다.

Chinese Idioms are important as a Part of Chinese Vocabulary, Korean learners who use Chinese as a second language understand and grasp the usage of the Chinese-Korean idiom，It will also play a significant role in learning Chinese for Korean learners. A Comparative Study on Chinese and Korean idiom of same patterns of synonyms provides many conveniences and references for Korean Chinese learners, Nevertheless, there are differences in Chinese and Korean of syntactic, semantic and pragmatic functions of idiom of same patterns of synonyms.

The purpose of this study is to develop guidelines for a Hindi A0 level evaluation test with its standardized Hindi curriculum. The development of a Hindi A0 level evaluation test is a basic requirement for ensuring internal stability of school education, because languages that uses special or unique characters that are not based on Roman alphabets, such as Hindi, Thai, and Persian, require a separate learning process or curriculum as well as their evaluation tests. This is not only in line with the purpose of the ‘Act on the Promotion of Education of Critical Foreign Languages’ enacted on August 2, 2016, but also because it can promote the substantiality of education in other critical foreign languages including Hindi, which had been conducted without a standardized curriculum. In other words, this study explores the concept of the A0 level that is not included in the CEFR, as a first step toward the realization of the ‘Common Asian Framework of Reference for languages’, the letters and pronunciations of which require a lot of time to learn. To this end, a guideline of an evaluation test for Asian languages is also proposed.

When evaluating the extent of the impact of water pollutants on the surrounding area, we would like to present the target level (proposal) of the quality of the environment, which is the standard for evaluation. We propose the environmental quality target level for substances that need to be applied domestically by investigating overseas cases operating the integrated environmental management system and the implications of domestic environmental pollutant management. The appropriateness of the environmental quality target level reviewed in this study was determined using data from the water quality measuring network, and future improvement measures were proposed. We review the available methodologies for setting quality objectives for the environment. It proposed the environmental quality target level for 21 substances that have domestic water pollutant emission standards and do not have environmental standards, and proposed future improvement measures. If it is necessary to add quality target-level items of the environment in the future, it is believed that expansion will be possible based on the methodology presented in this study.

Diets different in crude protein (CP) and undegraded intake protein (UIP) contents were offered to sheep in a metabolism study to describe their effects on nutrient digestibility and nitrogen (N) metabolism. Six Corriedale sheep (body weight=56.2±2.3 kg) were divided in random within a Latin square design (replicated) to 1 of 3 diets: 1) a low-CP diet (LP; 12.2% CP with 35.1% UIP), 2) high CP with low UIP diet (HPLU; 14.9% CP with 33.7% UIP), and 3) high CP with high UIP diet (HPHU; 15.5% CP with 45.8% UIP). High-protein dried distillers grain and soybean meal were the main CP sources for the adjustment of UIP:DIP in the diets. No significant differences were found in feed consumption and nutrient digestibility; however, a greater proportion of CP was digested in sheep fed the HPLU diet (69.4%; P=0.04). Although N intake was greater in sheep receiving HPLU and HPHU diets, loss of N through fecal or urinary route was not different among sheep, which resulted in the highest (12.7 g/d) and lowest N retention (7.40 g/d) in HPHU- and LP-fed sheep, respectively. In conclusion, although CP or UIP content had marginal effects on feed consumption and whole-tract digestibility of the majority of nutrients, with the increased CP and UIP levels in the diet, the efficiency of N utilization was improved with regard to increased N retention with minimal differences in N excretion, which is important from an economic and environmental standpoint.
