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.

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.

According to the amendment of the Enforcement Decree of the Public Records Management Act in 2020, an administrative information dataset record management plan will be enacted, and the National Archives of Korea plans to establish an integrated administrative information dataset management system to support it. However, there is no specific service plan that considers the characteristics of the datasets and the Management Reference Table. Therefore, this paper compared and analyzed the current status of dataset services at 14 domestic and foreign public data portals and archives websites, derived implications, and proposed 6 service plans applicable to the integrated administrative information dataset management system. This study's results will lead to utilizing the administrative datasets and the activation of services. 2020년 「공공기록물에 관한 법률 시행령」 개정에 따라 행정정보 데이터세트 기록관리 방안이 법제화되며, 국가기록원은 행정정보 데이터세트 기록관리 업무를 지원하기 위해 행정정보 데이터세트 종합관리시스템을 구축할 계획을 밝혔다. 하지만 데이터세트와 관리기준표의 특성을 고려한 구체적인 서비스 방안은 부재한 작금이다. 이에 본 논문은 국내⋅외 공공데이터 포털 및 기록관 웹사이트 14곳을 대상으로 데이터세트 서비스 현황을 비교 분석하고 시사점을 도출하여 행정정보 데이터세트 종합관리시스템에 적용 가능한 서비스 방안 6가지를 제안했다. 본 연구의 결과가 행정정보 데이터세트 활용 및 서비스 활성화로 이어지기를 기대한다.

The objective of this study was to predict land use change based on the land use change scenarios for the Hwangguji river watershed, South Korea. The land use change scenario was derived from the representative concentration pathways (RCP) 4.5 and 8.5 scenarios. The CLUE (conversion of land use and its effects) model was used to simulate the land use change. The CLUE is the modeling framework to simulate land use change considering empirically quantified relations between land use types and socioeconomic and biophysical driving factors through dynamical modeling. The Hwangguji river watershed, South Korea was selected as study area. Future land use changes in 2040, 2070, and 2100 were analyzed relative to baseline (2010) under the RCP4.5 and 8.5 scenarios. Binary logistic regressions were carried out to identify the relation between land uses and its driving factors. CN (Curve number) and impervious area based on the RCP4.5 and 8.5 scenarios were calculated and analyzed using the results of future land use changes. The land use change simulation of the RCP4.5 scenario resulted that the area of urban was forecast to increase by 12% and the area of forest was estimated to decrease by 16% between 2010 and 2100. The land use change simulation of the RCP8.5 scenario resulted that the area of urban was forecast to increase by 16% and the area of forest was estimated to decrease by 18% between 2010 and 2100. The values of Kappa and multiple resolution procedure were calculated as 0.61 and 74.03%. CN (Ⅲ) and impervious area were increased by 0-1 and 0-8% from 2010 to 2100, respectively. The study findings may provide a useful tool for estimating the future land use change, which is an important factor for the future extreme flood.

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.

김지혜,Beta Zenia Poliquit,남호성,김상헌,이용민,김광만,고장면 한국물리학회 2012 Current Applied Physics Vol.12 No.1

Dynamic cyclic voltammetry is performed as functions of cycle number and potential window for the electrodeposition of PteRueCo and PteRueNi catalysts on a carbon fiber (CF) web. Surface morphologies of the electrodeposited catalysts are observed by a scanning electron microscope. The electrochemical activity in methanol oxidation is examined by the cyclic voltammetry using a mixed aqueous solution of methanol as an electrolyte component. As the cycle number increases, both the current density and the amount of the electrodeposited metallic particles on the CF web are increased. The PteRueNi/CF catalyst prepared in the potential range of 0.6 to 0.2 V and from the 1:2:2 mixed solution of H2PtCl6,RuCl3·3H2O, and Ni(NO3)2·6H2O, respectively, shows the higher current density, corresponding to the higher catalytic activity.

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.
