김지혜,신창섭,김지혜,김도형,김윤수,이현채 인간식물환경학회 2020 인간식물환경학회지 Vol.23 No.3

Background and objective: In the Republic of Korea, military service is mandatory. Some of new recruits have the stress from the special environment, which could cause psychological maladjustment. The military forces have operated education programs such as green camp and healing camp. The study was conducted to investigate changes in psychological and physiological stress by conducting forest healing activities along with plant scent treatment for soldiers participating in a green camp. Methods: A total of 52 soldiers were participated including maladjustment soldiers and those recommended by their military units to protect the unfit soldiers who participated in forest healing activities in the green camp. The programs that were certified by the Korea Forest Service between 2014 and 2019, and were applied for stress reduction and relaxation training were classified into stress-coping programs and forest experience programs. Post-hoc surveys and cortisol measurements were carried out. Results: Green camp soldiers experience and differences in the level of stress responses were found to be very statistically significant between the treatment and control groups. The techniques for coping with stress were not significantly different in the control group, and the treatment group showed statistically significant results. In addition, the results of analyzing changes in the concentration of cortisol and measuring physiological stress were very statistically significant in forest healing activities at 4 p.m. Conclusion: Once green camp soldiers face stressful situations, forest healing programs using forest plant scents for green camp soldiers can have positive responses and forest healing activities can reduce psychological and physiological stress responses, improving maladjustment behaviors caused by stress and positively affecting the reduction of cortisol.

In Vivo Angiogenic Capacity of Stem Cells from Human Exfoliated Deciduous Teeth with Human Umbilical Vein Endothelial Cells

김지혜,남현,김지혜,김재원,편희장,이재천,이진 한국분자세포생물학회 2016 Molecules and cells Vol.39 No.11

Dental pulp is a highly vascularized tissue requiring ade-quate blood supply for successful regeneration. In this study, we investigated the functional role of stem cells from human exfoliated deciduous teeth (SHEDs) as a perivascular source for in vivo formation of vessel-like structures. Primarily isolated SHEDs showed mesenchymal stem cell (MSC)-like characteristics including the expression of surface antigens and in vitro osteogenic and adipogenic differentiation potentials. Moreover, SHEDs were positive for NG2, -smooth muscle actin (SMA), platelet-derived growth factor receptor beta (PDGFR), and CD146 as pericyte markers. To prove feasibility of SHEDs as perivascular source, SHEDs were transplanted into immunodeficient mouse using Matrigel with or without human umbilical vein endothelial cells (HUVECs). Transplantation of SHEDs alone or HUVECs alone resulted in no formation of vessel-like structures with enough red blood cells. However, when SHEDs and HUVECs were transplanted together, extensive vessel-like structures were formed. The presence of murine erythrocytes within lumens sug-gested the formation of anastomoses between newly formed vessel-like structures in Matrigel plug and the host circulatory system. To understand underlying mechanisms of in vivo angiogenesis, the expression of angiogenic cytokine and chemokine, their receptors, and MMPs was compared between SHEDs and HUVECs. SHEDs showed higher expression of VEGF, SDF-1, and PDGFRthan HUVECs. On the contrary, HUVECs showed higher ex-pression of VEGF receptors, CXCR4, and PDGF-BB than SHEDs. This differential expression pattern suggested reciprocal interactions between SHEDs and HUVECs and their involvement during in vivo angiogenesis. In conclusion, SHEDs could be a feasible source of perivascular cells for in vivo angiogenesis.

고농도 산소가 지적장애인의 혈중 산소 포화도와 심박동률 및 단기 기억에 미치는 영향

김지혜,류세진,김현주,최미현,연홍원,윤희정,김형식,전재훈,김영랑,정순철 대구대학교 특수교육재활과학연구소 2012 특수교육재활과학연구 Vol.51 No.2

본 연구에서는 92%의 고농도 산소 공급이 지적장애인의 단기기억력(0-back 과제 수행능력)과 생체 신호에 미치는 영향을 관찰하였다. 지적 장애 진단(평균 2.1±0.5급)을 받은 남자 7명(평균 28.9±1.8세)과 여자 7명(평균 34.4±8.3세) 총 14명을 대상으로 실험을 수행하였다. 실험은 고농도 산소 공급 전 Rest 구간(2분), 고농도 산소 공급 후 적응 구간인 Adaptation 구간(1분), 과제 수행 전 안정 상태를 유지하는 Control 구간(2분), 0-back 과제를 수행하는 Task 구간(2분)으로 구성되었다. 모든 실험 참여자는 21%와 92% 고농도산소의 두 가지 산소 농도에서 과제를 수행하였고, 전 구간에서 혈중 산소 포화도와 심박동 률을 측정하였다. 일반 공기중의 산소 농도인 21%에 비해 92%의 고농도 산소 공급 시 정답률은 증가하였으며, 혈중 산소 포화도는 증가하였고, 심박동률은 감소하는 경향이 나타났다. This study investigated changes in working memory (0-back task performance), blood oxygen saturation (SpO2 [%]), and heart rate (HR [bpm]) of intellectual and developmental disability people by supplying two different condition of oxygen (21%, and 92%). 7 males (average 28.9±1.8 years) and 7 females (average 34.4±8.3 years) in intellectual and developmental disability people were selected as the subjects for this study. The each run consisted of four phases, i.e., Rest (2 min.), Adaptation (1 min.), Control (2 min.), and Task (2min.). SpO₂ and HR were measured during each phase. The analysis of cognitive performance with 92% oxygen administration when compared to 21% oxygen revealed that the accuracy rate increased. When supplied 92% oxygen, the blood oxygen saturation was increased while the heart rate was decreased compared to those under 21% oxygen condition. This result supports the hypothesis that hyperoxic air increase oxygen saturation level in the blood, lead to more available oxygen to the brain, thus increase the ability of cognitive processing of intellectual and developmental disability people.

Objective: The object of this study is to evaluate the effect of dentifrice containing sodium bicarbonate and triclosan on the removal of kimchi and garlic odor and its 12 hours lasting efficacy. Methods: To confirm the efficacy of dentifrice on oral malodor in-vitro and clinical trials were conducted. Antibacterial activity on P. intermedia and removal efficacy of kimchi and garlic odor were measured by GC and a Halimeter, in-vitro. Clinical trials were designed by a double blind, crossover study design for subjects aged between 20-40. The removal effect of kimchi odor and its 12 hour long-lasting inhibitory effect of oral malodor were conducted by organoleptic evaluations and/or through a Halimeter. Results: Antibacterial activity on P. intermedia, experiment group 2 (sodium bicarbonate/triclosan), was under 100 CFU/ml. Experiment group 2 showed effective reduction in oral malodor using cultivated saliva with garlic. The result of measuring the effects removing acetic acid among the kimchi odor ingredients using GC showed that compared to the control group, the peak area of experiment group 2 decreased 52.28%. The result of sensory evaluation after brushing under the kimchi intake showed the statistically meaningful effect of oral malodor control for 2 hours after brushing than the control group (p<0.05). In clinical tests through sensory evaluation and Halimeter measuring oral malodor the controlling effect in 12 hours after brushing, the experiment group inhibited oral malodor control more than the control group (p<0.05). Conclusion: It is proven that dentifrice containing sodium bicarbonate and triclosan is more effective on oral malodor control than dentifrice without triclosan and sodium bicarbonate.

This study began with the recent changes in the demographic structure of the labor market in Korea and the changes in the diversification of the economically active population. It has been noted that the diversity of workforce composition is increasing as the number of people with different backgrounds and ages increases. In this context, this study focuses on internal human resources among various factors that determine organizational performance, and examines how the diversity of workforce composition affects public performance and efficiency performance. First, when the labor productivity score classified as the efficiency performance is used as the dependent variable, analysis shows that the diversity by age, gender, position, tenure of service, and level of education do not have any significant effect on the performance. Next, when the main business performance scores classified as public performance are used as dependent variables, diversity by tenure of service and level of education have a positive influence on performance. In this case, the non-linear influence of diversity is confirmed. Additional analysis showed that gender diversity has an inverse U-shaped influence, and diversity by level of education has a positive influence. 최근 우리나라 노동시장에는 인구통계학적 구조 및 경제활동인구의 다양화에 따른 변화가 발생하고 있는데, 특히 공공기관의 경우 여성, 청년, 고졸자 채용 확대 등 국가 정책과제의 시행으로 다양한 배경 및 연령을 가진 인력의 진입이 확대됨에 따라 인력구성의 다양성이 점차 증가하고 있는 상황이다. 이러한 맥락에서 본 연구에서는 조직성과를 결정짓는 다양한 요인 중 내부 인적자원에 초점을 두고 인력구성의 다양성이 공공기관의 공공성 및 효율성 측면의 조직성과에 어떤 영향을 미치는지 대해 알아보기 위해 공기업의 2009년부터 2015년까지 총 7년간 다양성지수와 경영실적평가 점수 간의 관계를 분석하였다. 연구결과에 따르면 근속연 수별, 학력수준별 다양성의 증가로 다양한 근속기간, 학력 및 배경을 가지는 구성원들이 공존하게 되면 조직은 구성원들에게 내재되어 있는 다양한 경력, 경험, 기술 및 정보를 공유하고 활용함으로써 성과에 긍정적인 영향을 유발하는 것으로 나타났다.

임화의 단편서사시의 의미와 ‘감정’의 분화

김지혜 한국문학연구학회 2015 현대문학의 연구 Vol.0 No.55

This paper attempts to reveal that some short epic poetries of Im Hwa, which had the meaning of 'a new style of proletariat poem', were the texts forming integrated sensitivity, beyond the dichotomy between aesthetics and ideology. Consequently, when the <My Brother and a Brazier>, an short epic poetry of him appeared, Kim Gijin and Im Hwa identified the 'emotion' as an important disposition and tried to differently establish each proletariat poem-type of emotion, respectively. Specifically, Kim Gijin believed that the proletariat poem, like the <My Brother and a Brazier>, could be successfully popularized by forming sympathy, a kind of emotion and stimulating readers' sensitivities for their classes. Meanwhile, Im Hwa conducted self-criticism on his own poetries by recognizing that Kim Gijin's emotion theory is just a 'sentimentalism' of the intellectual belonging to a bourgeois, and the sympathy is merely an emotion of the observer. Noteworthy is that reinforcement of an ideology in the proletariat poem is never directly led to weakening of the emotion. Instead, Im Hwa specified a social role of emotion through short epic poetries and planned the formation of revolutionary sensitivity. In other words, as the reason that the emotion can be an essence of the literature, he found that thought and behavior may be keys of the emotion and confirmed the emotion as a meaning of political practice, an 'impulsion in the behavior' Because of the short epic poetries, the emotion in the proletariat poem was positioned as ideological disposition which allowed the practice of revolution, rather than as aesthetical one which was excluded. 본고는 임화의 단편서사시 <우리 오빠와 화로>의 의미를 프로시의 새로운 양식이라는 점에서 찾는 기존 논의가 여전히 미학/이데올로기라는 이분법적 시각에 의거해 시의 사적 의의를 밝힌다는 점을 유념하고, 오히려 단편서사시가 미학/이데올로기라는 이분법을 넘어서는 통합적 감수성을 형성하는 텍스트임을 드러내고자 하였다. 결론적으로 말해, <우리 오빠와 화로>의 출현으로 인해 김기진과 임화는 프로시의 중요한 자질로서 ‘감정’을 발견하고 각기 다른 방향으로 ‘감정’의 의미를 분화시켜 갔음을 알 수 있었다. 통상적으로 이 시기 프로시는 문학의 이념화 또는 운동으로서의 문학이라는 정치적 입장을 강화하는 방향으로 나아갔다고 이해될 수 있지만, 이 시기 주목받은 작품 <우리 오빠와 화로>를 둘러싼 논의들을 보면, 동시에 그것은 일종의 프로시적인 감수성의 형성에 관한 담론이기도 했다. 그 과정에서 ‘감정’이 중요한 자질로서 선택되고 그 외연과 내포를 구축하고 있었던 것이다. 구체적으로 김기진은 <우리 오빠와 화로>처럼 프로시가 ‘동정’의 감정을 형성하여 독자의 계급적 감수성을 자극함으로써 프로시의 대중화에 성공할 수 있다고 보았다. 반면, 임화는 김기진의 감정론이 사실상 부르주아 지식인의 감상주의에 불과하며 동정의 감정이 관찰자의 감정이라는 점을 간파하고, 자신의 시에 대한 자아비판을 감행하게 된다. 주목할 것은 프로시에서 이념성의 강화가 결코 감정의 약화로 직결되지 않는다는 점이다. 오히려 단편서사시를 통과하면서 임화는 감정의 사회적 역할을 구체화 시켰다고 할 수 있는데, 궁극적으로 그것은 혁명적 감수성의 형성으로 나아간다. 즉, 임화는 감정을 문학의 본질일 수 있는 이유로서 감정이 사상과 행동을 요체로 한다는 점을 적극적으로 드러내고, 감정을 ‘행동에의 충동’이라는 정치적 실천의 의미로서 확정했던 것이다. 단편서사시 <우리 오빠와 화로>의 의미는 이 시로 인해 프로시에서 감정이 배제되는 미학적 자질이 아니라 혁명의 실천을 가능하게 하는 이념적 자질로 자리매김하게 되었다는 점에 있다.

Unlike a slender body, vortices are shed off alternately in the wake of a blunt body. In the case of liquid flows, when the pressure falls below the vapor pressure, cavitation occurs in the vortex core and affects the formation of the vortex street. This phenomenon is of major importance in many practical cases because the alternate shedding of vortices creates imbalanced forces on the body. Hence, it is very important to determine the shedding frequency of cavitating vortices. In this paper, the unsteady cavitating flow around a two-dimensional wedge-shaped submerged body was simulated using the commercial code STAR-CCM+. A numerical investigation of the structure of cavitating vortices was performed for a model with an apex angle of 20°. The results were validated by comparing them with experimental measurements carried out at a cavitation tunnel of Chungnam National University (CNU-CT). It was found that the shedding frequency of the vortex increased by up to 18%, which was strongly affected by the development of cavitation.
