  • This study explores the relationship between childhood abuse experiences and subsequent mental disorders in adults, with a particular focus on the moderating role of spiritual well-being. Using self-reported data from 210 graduate students in the Daejeon and Chungcheong regions, the findings demonstrate that spiritual well-being significantly moderate how childhood abuse impacts adult mental health. Specifically, individuals with lower levels of spiritual well-being experience a greater exacerbation of metnal disorders related to past abuse, while those with higher levels show a buffering effect. These results suggest that enhancing spiritual well-being could be a vital component of therapeutic interventions aimed at preventing mental disorders in adults who have experienced childhood abuse. We highlight the potential benefits of incorporating spiritual well-being into mental health strategies and call for additional research to substantiate these findings across broader populations. This unique contribution underscores the importance of considering spiritual factors int the therpeutic process, offering a new and valuable perspective in the field of mental health research.

  • The objective of this study was to investigate the effect of banana flower powder (BAFLOP) supplementation on gas production kinetics and rumen fermentation efficiency in in vitro incubation with different ratios of roughage to concentrate in swamp buffalo and cattle rumen fluid. Two male, rumen fistulated dairy steers and swamp buffaloes were used as rumen fluid donors. The treatments were arranged according to a $2{\times}2{\times}3$ factorial arrangement in a Completely randomized design by using two ratios of roughage to concentrate (R:C; 75:25 and 25:75) and 3 levels of BAFLOP supplementation (0, 2 and 4% of dietary substrate) into two different kinds of rumen fluid (beef cattle and swamp buffalo). Under this investigation, the results revealed that the rumen ecology was affected by R:C ratio. The pH declined as a result of using high concentrate ratio; however, supplementation of BAFLOP could buffer the pH which led to an improvement of ruminal efficiency. BAFLOP supplementation affected acetic acid (C2) when the proportion of concentrate was increased. However, there were no effect on total volatile fatty acid (TVFA) and butyric acid (C4) by BAFLOP supplementation. The microbial community was affected by BAFLOP supplementation, especially the bacterial population. As revealed by real-time PCR, the populations of F. succinogenes and R. albus were reduced by the high concentrate treatments while that of R. flavafaciens were increased. The populations of three dominant cellulolytic bacteria were enhanced by BAFLOP supplementation, especially on high concentrate diet. BAFLOP supplementation did not influence the ammonia nitrogen ($NH_3$-N) concentration, while R:C did. In addition, the in vitro digestibility was improved by either R:C or BAFLOP supplementation. The BAFLOP supplementation showed an effect on gas production kinetics, except for the gas production rate constant for the insoluble fraction (c), while treatments with high concentrate ratio resulted in the highest values. In addition, BAFLOP tended to increase gas production. Based on this study, it could be concluded that R:C had an effect on rumen ecology both in buffalo and cattle rumen fluid and hence, BAFLOP could be used as a rumen buffering agent for enhancing rumen ecology fed on high concentrate diet. It is recommended that level of BAFLOP supplementation should be at 2 to 4% of total dry matter of substrate. However, in vivo trials should be subsequently conducted to investigate the effect of BAFLOP in high concentrate diets on rumen ecology as well as ruminant production.

  • This study has been done for the purpose of determining whether the positive association between social support and depression is attributable to an overall beneficial effect of support(direct effect) or to a process of support protecting persons from adverse effects of stressors such as life events, pain or physical disability (buffering effect). The sample consisted of 214 patients who were identified as the rheumatoid arthritis. The instruments used in this study were Depression Scale(CES-D), Perceived Social Support Scale, Life Events Questionnaire, AIMS Pain Scale, and Physical Disability Scale. The data were analysed by the use of t-test, ANOVA, Pearson Correlation Coefficient and Stepwise Multiple Regression. The results of this study are summerized as follows : 1. The 1st hypothesis, "The higher the life events degree, the higher the depression degree" was supported(r=.49, P=.0001). 2. The 2nd hypothesis, "The higher the pain degree, the higher the depression degree" was supported(r=.44, P=.0001). 3. The 3rd hypothesis, "The higher the physical disability degree, the higher the depression degree" was supported (r=.46, P=.0001). 4. The 4th hypothesis, "The higher the social support degree, the lower the depression degree" was supported(F=84.52, P=.0001). 5. The 5th hypothesis, "There will be different in the relationship between the degrees of life events and depression according to social support degree" was rejected (F=.29, P=.5928). 6. The 6th hypothesis, "There will be different in the relationship between the degrees of pain and depression according to social support degree" was supported (F=3.19, P=.0755). 7. The 7th hypothesis, "There will be different in the relationship between the degrees of physical disability and depression according to social support degree" was supported(F=5.69, P=.018). 8. The predictive variables for depression were the degrees for social support, life events, pain, and physical disability. 9. The depression degree showed a inverse correlation with social support degree (r=-.56, p=.0001). The social support degree showed a inverse correlation with the degrees of life events(r=-.22, p=.0007), pain(r=-.18, p=.0069) and physical disability(r=-.15, p=.0293). 10. The depression degree showed significant differences in the variables of sex (t=2.26, p=.025), educational level(r=.189, P=.006) and the number of treatment method (r=.201, P=.003). In conclusion, it was found that social support had the direct effect on depression and the buffering effect in each relationship between degrees of pain or physical disability and depression in patients with rheumatoid arthritis. So the researcher thinks that it is effective that nurses should provide these patients with social support to reduce depression in cases of having severe pain or physical disability.

  • 이 연구의 목적은 타액이 산성일때 치아우식과 연관이 있는 Streptococcus mutans 와 Lactobacillus spp.의 양을 조사하여 치아우식의 지표로 사용될 수 있는지를 관찰한 외국인을 대상으로한 임상결과이다. 총 240개의 타액 표본들은 마케도니아(Macedonia), 스코프에(Skopje)에 위치한 St Kiril- Metodi 치과대학병원에서 환자 80명으로부터 얻었다. 표본들은 사전의 파라핀 저작(씹기)법에 의해 타액을 자극하여 얻어졌으나, 타액의 pH의 결정을 위해서 다른 자극은 사용되지 않았다. 치아우식 집단의 타액 1 ml에서 S. mutans는 100%의 confluent growth (CFU > $10^6$$10^4-10^5$) 였으나, Lactobacillus spp.는 78.3%였다. 대조표본 집단(건강하고 손상되지 않은 치아를 가짐)에서, confluent growth (CFU > $10^6$$10^5$)를 가지는 colony는 발견되지 않았다. 이와 달리, 두 집단 모두(60 + 20)에서 타액의 pH와 타액의 완충력으로부터 얻어진 결과는 상호연관이 있었다. 치아우식집단에서, 타액의 pH 결과치는 약산성(5.90 - 6.50)이었고, 타액의 완충력 역시 매우 낮았다(0.7ml 이하). 한편, 대조표본 집단에서, 타액의 pH는 중성(pH 7.01 - 7.7)이었고 타액 완충력은 높았다(1ml 이상). CRT-bacteria 시험법으로부터 얻은 타액 1 ml내($10^5$ CFU 이상)의 S. mutans와 Lactobacillus spp.의 증가된 수는 타액의 산성과 약산성 pH의 결과처럼 치아우식위험을 증가시켰다. 따라서, 타액 pH법과 완충력 측정법은 치아우식 위험을 예측 할 수 있으며, 치아우식 예방을 위해 유용한 측정법으로 사용될 수 있을 것으로 사료된다.

  • This purposes of study are to examine the effect of family related stress and social support on the ways of coping of adolescents and provide a ground necessary to improve it. A survey was conducted on 756 adolescents who were living in Naju. Collected data were analyzed by descriptive statistics, Pearson's correlation, and multiple regression analysis. This study utilized two different models, direct effect model and buffering effect of social support in order to examine the effects of social support on the ways of coping of adolescents. Research findings suggest that the level of coping appeared to be low in general among adolescents. The finding of direct effect model of social support was that mother's support, father's support, sibling's support, lather's grade, mother's grade, and economic level effected the ways of coping of adolescents. But it was not empirically supported that the social support buffered the family related stress on the ways of coping. In other words, the effects of family related stress factor didn't decrease with the increase in the level of social support, however the level of coping increased at a mercy of the age and economic level. Finally, this paper attempted to provide some alternatives to effectively improve the ways of coping among adolescents based on empirical findings.

  • 제주도 안디졸(Andisol) 토양 분포지역 중 화산성 쇄설물과 현무암으로부터 기원된 두 토양의 Bo층을 대상으로 완충능력을 계산하고 토양의 알루미늄 용해도가 완충능력에 미치는 영향을 연구하였다. 주상실험 결과는 pH 6.0과 4.0 부근에서 완충작용이 일어남을 보여 주며, 현무암기원의 토양보다 화산쇄설암기원 토양의 완충능력이 더 큰 것으로 나타났다. 다양한 pH조건에서의 배치평형실험 결과 다량의 알루미늄 함유 광물상을 갖는 제주도 안디졸 토양 Bo층에서의 알루미늄 거동은 $Al(OH)_3$, 이모골라이트 혹은 프로토-이모골라이트 등의 고상에 주로 영향을 받는 것으로 나타났다. Bo층 토양의 광물조성, 배치 평형실험결과, 그리고 주상실험 결과를 종합해 볼 때, pH 4.0 부근에서 나타나는 뚜렷한 완충능력($\beta$)은 깁사이트 및 프로토-이모골라이트의 용해도 특성에 의해서 좌우되는 것으로 해석된다. pH 6.0 내외의 완충작용은 규산염광물의 용해도 및 염기성양이온의 양이온교환반응에 의해 진행되고 있으나, 낮은 염기성 포화도는 토양산성화가 더 진행될 경우 이러한 완충효과가 오래 지속되지 못할 것임을 지시한다.

  • This study was conducted to optim ize the composition of CEM (cabbage extract medium) and cryoprotectants on the growth of Lactobacillus plantarum, a probiotics growing in plant and milk. For this, we analyzed the growth characteristics of Lb. plantarum in CEM and subsequently optimized the medium composition by addition of carbon, nitrogen sources and buffering agents. Among carbon sources, glucose showed the best result to increase the cell density after dilution of CEM. When 0.5% yeast extract and 1% soy peptone were supplemented in the diluted CEM, Lb. plantarum grew up to the maximum cell density. Addition of buffering agents in CEM was not significantly effective to increase the cell density. Meanwhile, addition of 12% skim milk, 5% sucrose and 0.5% glycerol showed a cryoprotective effect against cell damage of Lb. plantarum during freeze drying process showing high survival rate after 150 days. This optimized CEM can be used for economical production of bacterial cells particularly originated from a plant-related ecosystem.

  • Objectives: This study was aimed at evaluating the effects of changes in the oral environment of the elderly in long-term care facilities after the intake of Weissella cibaria. Methods: The test group ingested the W. cibaria strain Chonnam Medical University (CMU), and the control group ingested the control food. Of all randomized trial subjects, 62 were analyzed (32 in the experimental group and 30 in the control group). In this 8-week demographic study, we evaluated self-perceived halitosis, changes in halitosis, sensory test results, tongue plaque index scores, saliva buffering capacity, and the salivary flow rate. Results: The W. cibaria CMU intake in the elderly in long-term care facilities during the experimental period did not demonstrate statistically significant changes in the salivary flow rate. However, self-perceived halitosis, organoleptic test results, tongue plaque index scores, and salivary buffering capacity demonstrated statistically significant differences between the experimental and control groups. These findings partially confirmed the beneficial effects of the W. cibaria CMU on the oral environment in the elderly. Conclusions: Research results on the role of probiotics in the oral cavity should be summarized, and utilization plans should be sought to obtain a clearer understanding of the clinical efficacy and related factors. The value of probiotic use may be high in improving the oral health of people by enabling treatment and prevention.

  • Background: The limited studies on the effect of buffering on the clinical efficacy of articaine have reported controversial results. The purpose of this study was to clinically compare the pain of injection, anesthetic success, onset, and duration of pulpal anesthesia of buffered 4% articaine with epinephrine 1:100000 versus a non-buffered 4% articaine with epinephrine 1:100000 formulation for buccal infiltration of the mandibular first molar. Methods: Sixty-three volunteers were enrolled in the study. All volunteers received two injections consisting of a single mandibular first molar buccal infiltration with 1.8 ml of 4% articaine with epinephrine 1:100000 and 1.8 ml of 4% articaine with epinephrine 1:100000 buffered with 8.4% sodium bicarbonate. The infiltrations were applied in two separate appointments spaced at least one week apart. After injection of the anesthetic solution at the examined site, the first molar was pulp-tested every 2 min for the next 60 min. Results: Successful pulpal anesthesia was recorded in 69.8% of cases using non-buffered articaine solution and 76.2% of cases using buffered articaine solution, with no significant difference between the formulations (P = 0.219). The mean time of anesthesia onset for the volunteers with successful anesthetic outcome in both formulations (n = 43) was 6.6 ± 1.6 min for the non-buffered articaine solution and 4.5 ± 1.6 min for the buffered solution, which differed significantly (P = 0.001). In the same volunteers, the mean duration of pulpal anesthesia was 28.4 ± 7.1 min for non-buffered articaine solution and 30.2 ± 8.5 min for buffered articaine solution, with no significant difference between the formulations (P = 0.231). Considering the pain of injection, regardless of the anesthetic success, the mean values of VAS were 11.3 ± 8.2 mm for the non-buffered articaine solution and 7.8 ±6.5 mm for the buffered articaine solution, which differed significantly (P = 0.001 < 0.05). Conclusion: According to the present study, 4% articaine with epinephrine can benefit from buffering and provide better anesthetic behavior, with improved onset and less pain during injection.
