  • This study was aimed at evaluating a proper mixing ratio of making Beaknyuncho(Opuntia ficus-indica var. saboten) Sulgidduk with different types of extraction, a fruit and a stem of Beaknyuncho, and by different making methods. As a result, moisture content was the highest(43.22%) in FP1 and the lowest(38.55%) in SJ60. The low lightness and yellowness are increased with more powder and juice of both fruit and stem added. The mechanical characteristics, hardness, adhesiveness and gumminess were increased as powder and juice were added. And cohesiveness and springiness were decreased. The identification test showed that a sample containing stem juice was the most preferable for taste, chewiness, moistness and after-taste. The preference test showed that a sample containing stem juice was the most preferable for color, texture and overall quality and a sample containing stem powder was preferable for flavor and taste. Both SJ60 mixed with 60% Beaknyuncho stem juice and FP3 mixed with 3% fruit powder proved to be the most desirable in both sensory evaluation and texture characteristics.

  • Objective: The effects of the pre- and postpartum supplementation of cows with Se on their plasma P4 concentrations after calving were investigated. Methods: Thirty-four Holstein cows were used to investigate the effects of dietary selenium supplementation on the postpartum recovery of the luteal function in cows. Selenium-rich yeast (containing 300 ppm selenium) was mixed with total mixed ration fed to 17 pregnant cows from 30 days before they were due to calve (10 g yeast daily) to 100 days after calving (20 g yeast daily). The control cows (n = 17) were fed the same amount of ordinary yeast. The cows' plasma progesterone concentrations were determined every two days using an enzyme immunoassay after calving. Results: Feed intake (total digestive nutrient, crude protein), milk production, body weight and the biochemical properties of blood plasma did not differ between the two groups; however, the plasma selenium concentrations of the supplemented animals were significantly greater than those of the controls at and after calving. The postpartum plasma progesterone concentrations of the selenium-yeast-supplemented group increased earlier than those of the control group. Moreover, during the estrus cycle after the 3rd ovulation or ovulation with estrus between 60 to 80 days after calving, the selenium-supplemented cows exhibited greater progesterone concentrations than the control cows. Conclusion: Selenium supplementation promotes the postpartum progesterone production of cows.

  • Concepts related to the fraction should be taught with formative thinking activities as well as concrete operational activities. Teaching improper fraction should follow the concept of fraction as a relation of two natural numbers. This concept is also important not to be skipped before teaching the fraction such as "4 is a third of 12". Mixed number should be taught as a sum of a natural number and a proper fraction. Fraction as a quotient of a division is a hard concept to be taught since it requires very high abstractive thinking process. Learning the transformation of division into multiplication of fractions should precede that of fraction as a quotient of a division.

  • Purpose: This study investigated knowledge of atopic dermatitis and food allergies, as well as health information literacy, among North Korean refugee mothers with preschool-age children and explored how these variables were related to participants' characteristics. Methods: A descriptive study design was used. Data from 130 North Korean refugee mothers were collected between January and March 2023. Results: The mean scores were 14.48 of 30 for atopic dermatitis knowledge; 2.77 of 10 for food allergy knowledge, and 56.95 of 80 for health information literacy. Significant differences were observed in knowledge of atopic dermatitis based on breastfeeding duration (F=4.12, p=.009), and in knowledge of food allergies based on mixed feeding (F=3.11, p=.049). Health information literacy showed significant relationships with education level (F=3.76, p=.026), occupation (F=3.99, p=.021), checking nutritional information (t=2.91, p=.004), mixed feeding (F=4.50, p=.014), and atopic dermatitis diagnosis (t=6.86, p=.001). Significant positive correlations were observed between atopic dermatitis knowledge, food allergy knowledge, and health information literacy. Conclusion: Personalized educational programs should be implemented to improve awareness of allergies and health information literacy among North Korean refugee mothers, which would help them find, evaluate, and understand health-related information. These programs should focus on providing nutrition and dietary education to promote healthy growth in children and prevent diseases.

  • This study has a goal to read a trend of language research by analysing evaluation tools and methods that researchers have used for assessing young children's language abilities. Thus the study has chosen 237 language ability evaluation methods out of 121 young child's language ability evaluation researches. The treatises were selected from 4 types of early childhood education journals registered on the Korea Research Foundation. The data analysis was employed for processing the frequency and percentage of the collected data. The results were as follows: First, of single age groups the subject group most selected was five-year-olders and of mixed-age groups the subject group most selected was from three to five, and the number of subjects in researches were mostly below fifty children. The researches were sorted into an 'experimental/ investigational researching' type that has been frequently re-utilized by others, an 'interview type' using a data collection method, and a 'difference verification' type using a data analysis method which has been used in majority of studies. Second, the number of treaties that required data analysis has increased since 1996. Concludingly, the analysis of young child's language ability evaluation tools shows that the purposes of many researches were concentrated on studying children's knowledge about language, children's language functions such as speaking, reading, writing and listening, while evaluation contents were focused on speaking and writing.

  • Destructive methods are used for the turnup determination of an irradiated PWR fuel. One of the methods includes U, Pu, Nd-148 and Nd-(145+146) determination by an isotope dilution mass spectrometry using triple spikes (U-233, Pu-242 and Nd-150). The method involves two sequential ion exchange resin separation procedures. Pu is eluted from the first anion exchange resin column (Dowex AG 1$\times$8) with 12 M HCl-0.1 M HI mixed solution, followed by U elution with 0.1 M HCl. Nd is isolated from other fission products on the second anion exchange resin column (Dowex AG 1$\times$4) with a nitric acid-methanol eluent. Each fraction is analysed by thermal ionization mass spectrometry. The difference between Nd-148 and Nd-(145+146) method is found with an average 2.07%. The results are compared with those by the heavy element method using U and Pu isotopes and by the destructive y-spectrometric measurement of Cs-137. The dependences of isotope composition of U and Pu on burn-up, and correlation between those isotopes are illustrated graphically.

  • The interspecific estimation for tolerance capacities of upland crop species to excessive soil water stress in paddy field is significant in agricultural practices. Most of upland crops can be damaged by either excessive soil water or capillary rise of the water table during rainy season in paddy fields. The major objective of this study was to evaluate water stress of upland crops under different drainage classes in converted paddy field. This experiment was carried out in poorly drained soil (PDS) and imperfectly drained soil (IDS) of alluvial sloping area located at Toero-ri, Bubuk-myeon, Miryang-si, Gyeongsangnam-do. The soil was Gagog series, which was a member of the fine silty, mixed, nonacid, mesic family of Aeric Endoaquepts (Low Humic-Gley soils). Two drainage methods, namely under Open ditch drainage methods (ODM) and, Closed pipe drainage methods (PDM) were installed within 1-m position at the lower edge of the upper paddy fields. The results showed that sum of excess water days ($SWD_{30}$), which was used to represent the moisture stress index, was 42 days (the lowest) in the PDM compared with 110 days in the ODM. Most of upland crops were more susceptible to excessive soil water during panicle initial stage on more PDS than on IDS. Yield of upland crops in the PDM was continuously increased by the rate of 15.1% on sorghum, 15.4% foxtail millet, 53.6% proso millet, 49.6% soybean and 47.9% adzuki bean as compared in the ODM. The capacity for tolerance by excessive soil water based on yield of each upland crop in the poorly drained sloping paddy fields was the order of sorghum, soybean, foxtail millet, proso millet and adzuki bean. Therefore, Sorghum is relatively tolerant to excessive soil water conditions and, may be grown successfully in converted paddy field.

  • Objectives: This study investigates the impact of M&L psychotherapy on an adolescent with anxiety disorders transitioning into adulthood, using a retrospective mixed-method approach. Methods: An adolescent with Diagnostic Statistical Manual of Mental Disorders (DSM)-5-diagnosed anxiety disorders underwent combined treatment with M&L psychotherapy and complex Korean medicine therapy over a period of approximately two years. Patient records tracked the diagnosis, treatments, and progress. In-depth interviews were also conducted. The study used a convergent parallel mixed-method approach, integrating quantitative analysis from psychological assessments, including the State-Trait Anxiety Inventory (STAI-X), the Core Seven Emotions Inventory-short form (CSEI-s), and the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), with qualitative analyses of traditional Korean medicine counseling session notes, interviews, and other qualitative psychological assessments. Results: State anxiety decreased from 40 to 36, and trait anxiety decreased from 42 to 34. MMPI-2 L scale scores decreased slightly to 64T, whereas S scale scores increased to 62T, and FRS scores decreased to 70T from an initial score of 78T. Qualitative analysis revealed an increase in the MMPI-2 Es scale, identified as "subjectivity." Joy (喜) emerged as the highest emotional profile score in the CSEI-S. Scores for anger (怒), thought (思), fear (恐), and fright (驚) decreased, indicating improved negative emotions. Qualitatively, expressions of determination to "move forward" and "strengthen the mind" were noted, suggesting enhanced "lower danjeon (下丹田)." Conclusions: Integrating traditional Korean medicine treatment with M&L psychotherapy for a vulnerable adolescent with anxiety disorders demonstrated efficacy. Further research is warranted to substantiate the effectiveness of M&L psychotherapy and advocate for its wider adoption in mainstream practice.

  • To improve freshness maintenance function of food containers, many methods have been applied. Most of the methods utilize absorption properties of porous ceramics powders. However, this kind of methods was appeared to be a non-realistic one because of the short effective periods of the produce and reduced die life due to the ceramic powders mixed in the raw materials. Other methods, e.g., CA or MA, need more study for practical application bemuse of the high cost in process. In addition to this, different method should be applied depends on foods. In this paper, a new technology based on information templation was applied in making a food preservation film. It has been known recently that water memorizes informations and this information could be tempelated to other materials through appropriate pretest. One of the participating company developed this process to template informations to PE materials unitizing water as an information rallier. Food packaging film was made using this PE chips. Experimental results of freshness maintenance test of foods showed that it is effective. Results and disussions are reported in this paper.
