Bacterial infection of the uterus in Hanwoo can kill embryos. Therefore, many antibiotics have been used to treat this infection in the uterus of repeat breeders. Incorrect use of antibiotics has led to resistance in bacteria. Natural compounds have used as substitutes for antibiotics because they are safe and have very mild side effects. This study was conducted to examine the antimicrobial effects of five extracts from medicinal plants including Humulus japonicas (Hj), Phelledendron amurense (Pa), Viola mandshurica (Vm), Carthamus tinctorius (Ct), and Chelidoni herba (Ch) on bacteria isolated from the uterus of Hanwoo using the paper disc diffusion method. Hj and Pa extracts had potent antimicrobial effects against Staphylococcus lentus, Streptococcus infantarius subsp. coli, and Bacillus pumilus. Pa had the greatest antimicrobial effect among the five medicinal plants and was effective against 19 types of bacteria from bovine uterus. Compared to Pa, Hj showed weaker antimicrobial effects on all the bacteria tested except Pseudomonas aeruginosa. Vm, Ct, and Ch also showed weak antimicrobial effects on the tested bacteria. The results obtained suggest that Hj and Pa are natural compounds suitable for treating bacterial infection in repeat breeders and improving conception rates of Hanwoo.

Despite significant effects on macroscopic migration and distribution of CO₂ injected during geological sequestration, only limited information is available on wettability in microscopic scCO₂-brine-mineral systems due to difficulties in pore-scale observation. In this study, a micromodel had been developed to improve our understanding of how scCO₂ flooding and residual characteristics of porewater are affected by the wettability in scCO₂-water-glass bead systems. The micromodel (a transparent pore structure made of glass beads and glass plates) in a pressurized chamber provided the opportunity to visualize scCO₂ spreading and porewater displacement. CO₂ flooding followed by fingering migration and dewatering followed by formation of residual water were observed through an imaging system. Measurement of contact angles of residual porewater in micromodels were conducted to estimate wettability in a scCO₂-water-glass bead system. The measurement revealed that the brine-3M NaCl solution-is a wetting fluid and the surface of glass beads is water-wet. It is also found that the contact angle at equilibrium decreases as the pressure decreases, whereas it increases as the salinity increases. Such changes in wettability may significantly affect the patterns of scCO₂ migration and porewater residence during the process of CO₂ injection into a saline aquifer at high pressures.

초임계상 이산화탄소 주입으로 인한 공극수 대체에 관한 공극 규모의 마이크로모델 연구

A micromodel was applied to estimate the effects of geological conditions and injection methods on displacement of resident porewater by injecting scCO₂ in the pore scale. Binary images from image analysis were used to distinguish scCO₂-filled-pores from other pore structure. CO₂ flooding followed by porewater displacement, fingering migration, preferential flow and bypassing were observed during scCO₂ injection experiments. Effects of pressure, temperature, salinity, flow rate, and injection methods on storage efficiency in micromodels were represented and examined in terms of areal displacement efficiency. The measurements revealed that the areal displacement efficiency at equilibrium decreases as the salinity increases, whereas it increases as the pressure and temperature increases. It may result from that the overburden pressure and porewater salinity can affect the CO₂ solubility in water and the hydrophilicity of silica surfaces, while the neighboring temperature has a significant effect on viscosity of scCO₂. Increased flow rate could create more preferential flow paths and decrease the areal displacement efficiency. Compared to the continuous injection of scCO₂, the pulse-type injection reduced the probability for occurrence of fingering, subsequently preferential flow paths, and recorded higher areal displacement efficiency. More detailed explanation may need further studies based on closer experimental observations.

For high quality of software, it should be necessary for defining and analyzing the exact requirements at the early stage of software development. But readability and understandability of most natural language requirements are inaccurate and difficult for identifying use cases. The requirements are duplicated for objects or temrs with the same meaning. To solve this problem, it should need an effective way of requirement analysis based on linguistic and semantic textual analysis. In this paper, we propose to improve a semantic analysis method adopted with a linguist Fillmore's linguistic mechanism. This method may expect to analyze easily readable and exactly understandable requirements specifications through modeling the goal oriented use cases with natural language based requirements. 고품질의 소프트웨어를 개발하기 위해서는 개발 초기단계에 정확한 요구사항 정의 및 분석이 필요하다. 그러나 대부분의 자연어 기반의 요구사항 문장 표현은 부정확성과 이해도 어려운 실정이다. 또한 요구사항은 같은 의미를 가진 객체나 용어들이 중복 식별된다. 이를 해결하기 위해 고객 요구사항을 언어학적 및 의미적 문맥 분석을 통한 효율적인 요구사항 분석 방법이 필요하다. 본 논문에서는 요구공학 언어학자인 Fillmore의 의미론적 분석 방법을 요구공학에 접목하고, 의미론적 분석 개선 방안을 제안한다. 이 방법은 자연어 기반의 요구사항을 Goal Oriented Use Case Modeling 통해 쉽게 읽고 이해 가능한 요구 사항 분석이 기대된다.

Silk textile has been used for a long time owing to its soft texture and luster. However, its limited elasticity has restricted its textile application causing end users to demand silk textile with improved features such as good extensibility and elasticity. In this study, the silk textile was prepared with high twist silk yarn and subjected to heat treatments to augment its elasticity. The effect of heat treatment on the morphology and mechanical properties of silk textile was examined. As the water temperature and drying temperature increased, the shrinkage ratio of silk textile increased causing the weft silk yarn to become tangled. Further, the breaking strength of silk textile decreased and its elongation increased significantly. Most silk textiles, except the ones immersed in water and dried at $25^{\circ}C$, showed an elastic recovery of 100%. However, the results of tough repetitive extension tests (at 150% elongation condition) showed a small permanent extension of silk textile at the end of the first extension cycle.

선교적 과제로서의 젠더 통합적 리더십(Gender Inclusive Leadership) 형성을 위한 방안

박보경(Bokyoung Park) 한국선교신학회 2016 선교신학 Vol.41 No.-

이 글은 한국교회가 직면한 수직적, 위계적 리더십 구조를 극복하기 위한 선교적 대안으로서 젠더 통합적 리더십(gender inclusive leadership)을 제안한다. 현대의 한국사회는 교육의 기회에 있어서는 남녀의 차별이 없는 것 같으나 일단 사회 속으로 진출하게 되면 심각한 성차별의 유리천장을 경험한다. 그런데 한국교회 안에서의 성차별의 문화는 사회보다 더 심각하다. 이 글은 이어서 여성의 리더십을 증진하기 위하여 리더십의 발휘에 있어서 여성과 남성이 어떻게 차이가 있는지를 조사한 연구들을 살펴보았다. 성과 리더십의 관계를 규명하는 연구들은 1980년도부터 본격화되었는데, 특히 여성들은 남성에 비해 더 민주적인 리더십을 발휘하는 경향이 있으며, 거래적 리더십보다는 변혁적 리더십을 발휘하는 경향이 있음이 밝혀졌다. 이런 여성적 리더십은 조직문화 안에서 보다 다양한 관점을 제공하여 의사결정과정에 보다 바람직한 선택을 하도록 돕는다. 따라서 최근에는 여성들이 리더십 의사결정 과정에 참여토록 함으로써 조직문화의 효율성을 꾀하고 있다. 이런 연구에 기초하여 선교적 과제로서의 젠더 통합적 리더십의 함양을 위하여 필자는 몇 가지 방안을 제안하였다. 첫째, 젠더 통합적 리더십의 형성을 위해서 영적 리더로서 잠재력 있는 여성목회자들을 발굴하고, 여성이 리더십 지위를 수행할 수 있도록 길을 열어야 한다. 둘째, 여성 스스로의 리더십 역량의 증진을 위한 부단한 노력이 필요하다. 셋째, 젠더 통합적 리더십의 형성을 위하여 여성들에게 필요한 또 하나의 과제는 자기연민과 수동성을 극복하는 것이다. 넷째, 여성적 리더십의 바람직한 모델을 현장의 이야기 속에서 발굴해야 하는데, 왜냐하면 이런 긍정적 여성리더의 이미지를 구축함으로 더욱 구체화되기 때문이다. 다섯째, 기혼여성 목회자들의 목회영역의 경력단절 현상을 극복할 수 있는 방안을 마련할 필요가 있다. 여섯째, 온전한 젠더 통합적 리더십의 형성은 남성들의 협력이 절대적으로 필요하다. This study suggest new gender inclusive leadership as the alternative approach to the hierarchical leadership structure prevalent in Korean churches. In the modern Korean society, while women obtain the equal opportunity for education, yet when they enters in the public sphere, they face serious glass-ceiling of gender discrimination. Women were discriminated also in the church due to the highly patriarchal culture. Then the study address the distinctive characteristics of woman in leadership. The study on women leadership has started during 1980s and continued to develop its components. Overall the study concluded that women's leadership tends to be more democratic and more transformational than that of men. Inclusion of female in the leadership and decision-making process results in successful and effective performance in the management of various corporations and organizations. Then, the study had suggested six points to enhance the gender inclusive leadership; first, searching for potential women leaders among women pastors; second, allowing women leader to empower themselves and increase their leadership competence; third, overcoming female stereotype such as self-pity, low- self esteem, and passivity; fourth, developing role-model of women in leadership so that such stories can concretize and inspire other women; fifth, finding a way to solve reentry problems for the married women pastors, and finally, cooperating from male leaders in the churches.

파킨슨병 환자의 음성조절훈련 전·후 호흡, 말속도 및 말명료도 점수 비교

박보경(Park, Bo-kyung),최예린(Choi, Yae-lin) 한국통합치료학회 2021 통합치료연구 Vol.12 No.2

본 연구의 목적은 파킨슨병 환자 1명을 대상으로 음성조절훈련을 구성하여 최대발성지속시간, 말속도(문장읽기속도), 말명료도(자발화)에서의 전·후 차이를 알아보는 것이다. 연구는 4주 간 주 3회 30분씩 총 12회기를 진행하였으며, 프로그램은 조음기관훈련, 호흡훈련, 음성조절훈련 순으로 실시하였다. 조음기관훈련에서는 혀, 볼, 입술운동을 진행하였고 호흡훈련은 울트라브리드를 이용하여 실시하였다. 음성조절 훈련은 일상생활에서 자주 사용하는 단어와 문장과제에서 강도와 음도를 동시에 점진적으로 높이거나, 낮추는 훈련, 강도는 크게 하면서 음도는 낮추기, 강도는 작게 하면서 음도는 높이는 훈련을 하였다. 마지막 훈련은 연구자가 제시하는 말속도에 맞춰 강한 강도로 문장읽기와 대화하기를 실시하였다. 그 결과 음성조절훈련 실시 전·후 최대발성지속시간, 말속도, 말명료도에 호전을 보였다. 이러한 결과는 음성조절훈련이 파킨슨병 환자의 호흡 길이를 증가시키고 말속도를 감소시키며 말명료도를 개선시키는 것에 영향을 미치는 것으로 볼 수 있다. 하지만 본 연구는 1명을 대상으로 진행했으므로 결과를 일반화하기에는 어려움이 있다. 따라서 추후 연구에서는 다수의 파킨슨병 환자들을 대상으로 적용해서 확장시킬 필요성이 있을 것이다. The purpose of this study was to establish a Voice Control Training for one patient with Parkinson s disease to examine the difference in the maximum vocal duration, speech rate (sentence reading speed), and speech intelligibility (voluntary speech) before and after the training. The study was conducted 12 times, 30 minutes a week for 4 weeks. The program was followed by Articulation Training, Breathing Training, and Voice Control Training. In the Articulation Training, tongue, cheek and lip movements were performed and Breathing Training was performed using Ultrabreathe??. In the words and sentences that are frequently used in daily life, the Voice Control Training Program conducted a training which gradually increase or decrease the intensity and pitch at the same time or increase the intensity while decreasing the pitch or decrease the intensity while increasing the pitch. The final training of this program was to read sentences and communicate with a strong intensity at the pace of the words the researcher suggested. As a result, it showed improvement in maximum vocal duration, speech rate and speech intelligibility before and after the Voice Control Training. These results suggest that the Voice Control Training affects the increase in breathing length, decreases speech rate and improves speech intelligibility in Parkinson s disease patients. However, since this study was conducted with one person, it is difficult to generalize the results. Therefore, future studies will need to be extended to a large number of Parkinson s patients.
