Hot Electron Transfer Kinetics in Aggregation-Induced Nanoscale Reactor

배주은,김영수 한국공업화학회 2020 한국공업화학회 연구논문 초록집 Vol.2020 No.-

Plasmonic metal nanoparticles have been received increasing attention as visible-light-driven photocatalysts due to their unique optical property by localized surface plasmon resonance (LSPR). However, the electron transfer kinetics of photocatalytic reactions in the colloidal system is limited by the diffusion of the chemical moieties to the vicinity of photocatalysts. To achieve the high-efficiency photocatalysts, It would be a key point that the diffusion length of chemical species for photochemical reaction needs to be shortened. To do this, we designed a nanoscale reactor, in which the chemical species can be confined closely near the photocatalysts, through the surface engineering of nanoparticles and a type of additive. We examined the electron transfer kinetics between the free-standing colloidal nanoparticle system and the colloidal nanoreactor system.

개인형 이동장치의 주행 안전성 및 이동성 평가 연구: 행정중심복합도시 1생활권을 중심으로

배주은,이수진,김충호 국토연구원 2022 국토연구 Vol.113 No.-

This study aims to evaluate the driving safety and mobility of personal mobility devices and to derive the correlation between driving characteristics and driving environments, focusing on the First Neighborhood District of the Multifunctional Administrative City. For this, the study presented a methodology to evaluate the driving safety and mobility of personal mobility devices, and measured acceleration and speed in the driving process after selecting normal bicycles, electric bicycles, and e-scooters as driving test devices. Then, the study conducted correlation analysis, cluster and outlier analysis, and multiple regression analysis in order to understand the effects of driving environments on driving characteristics. As a result, the research reached the following conclusions. First, regardless of the type of personal mobility device, the correlation between driving safety and driving mobility was found to be low overall. Next, the effects of driving environments on driving characteristics differed for each type of personal mobile devices. In terms of driving safety, e-scooters were more affected by road surface environments than electric bicycles. On the other hand, in terms of driving mobility, in addition to road type variables, situational factors such as competition with pedestrians and other personal mobility devices were also judged to be important. 본 연구는 행정중심복합도시의 1생활권을 중심으로 개인형 이동장치의 주행특성을 주행 안전성과 이동성 측면에서 평가하고, 주행특성과 주행환경의 상관관계를 도출하고자 하였다. 이를 위해, 개인형 이동장치의 주행 안전성과 이동성을 평가하는 방법론을 제시하였으며, 일반자전거, 전기자전거, 전동킥보드를 주행실험 장비로 선정하여 주행과정에서의 가속도와 속도를 측정하였다. 이어서, 주행환경이 주행특성에 미치는 영향을 파악하기 위해 상관분석, 클러스터 및 이상치 분석, 다중회귀분석을 실시하여 다음과 같은 결론에 도달하였다. 우선, 개인형 이동장치의 유형과 상관없이 주행 안전성과 주행 이동성의 상관관계는 전반적으로 낮게 나타났다. 다음으로, 개인형 이동장치의 유형별로 주행환경이 주행특성에 미치는 영향은 다르게 나타났다. 특히, 주행 안전성 측면에서 전동킥보드는 전기자전거에 비해 노면 환경에 더 큰 영향을 받은 것으로 분석되었다. 한편, 주행 이동성 측면에서 도로 유형의 변수 외에 보행자 및 다른 개인형 이동장치와의 경합 등 상황적 요소 역시 중요한 것으로 판단되었다.

Objectives: The purpose of this study is to investigate the effect on both herbal medicine periodic therapy and western medicine for polycystic ovary syndrome subfertility. Methods: We searched 8 electronic databases and search keywords were 'PCOS' and 'periodic therapy' or 'cyclic treatment'. We included randomized controlled clinical trials (RCTs) using the periodic therapy combined western medicine for PCOS patients. Results: We selected 8 studies. In studies, there were three studies in which the menstrual cycle was divided into 2 periods, one study divided into 3 periods, and four study divided into 4 periods. The meta-analysis of the 7 trials indicated that pregnancy rates integrated clomiphene and periodic therapy were higher than clomiphene alone. Conclusions: The periodic therapy combined western medicine for PCOS subfertility patients seems to improve pregnancy rates from this research. However, this result should be taken cautiously by unclear risk of bias. It would be necessary to fulfill further clinical study with herbal medicine periodic therapy on PCOS in Korean medicine to establish standard evidence of them.

Objectives: The purpose of this review was to overview and evaluate the efficacy of acupoint sticking therapy for women with endometriosis. Methods: We searched for randomized controlled clinical trials (RCTs) using acupoint sticking therapy on endometriosis in 5 electronic databases such as EMBASE, Pubmed, and CAJ. The results of the studies were analyzed and the risk of bias was assessed by using Cochrane risk of bias tool. Results: Two RCTs were included for analysis. In the selected studies, Treatment group was higher effective cure rate than any control group. In one RCT, Acupoint sticking therapy was only used, but the other RCT was treated acupoint sticking therapy combined with acupuncture. So, Interventions in 2 studies were not same, Quantitative synthesis was impossible. Conclusion: The limitation of this review is that the number of studies included is small. However, our systematic review provides a basis for acupoint sticking therapy for endometriosis. Acupoint sticking therapy was considered as one of external treatment method for patients with endometriosis.

본 연구는 물리적, 환경적, 사회적인 문제를 일으킬 수 있는 태양광 발전시설이 적절한 입지에 설치되어 있는지 평가하기 위해, 경상남도 거창군 태양광 발전시설을 대상으로 입지 현황을 유형화하고, 입지 유형별 특성을 분석하였으며, 태양광 발전시설의 입지 유형별 관리 방안에 대한 정책적 시사점을 도출하였다. 이에 따라, 본 연구는 다음과 같은 결론에 도달하였다. 첫째, 태양광 발전시설의 입지 유형은 일사량, 경사도, 경사향, 주거지와의 거리, 도로와의 거리에 따라 5개 유형으로 분류하였으며, 각 유형마다 고유한 특성이 있었다. 둘째, 거창군의 태양광 발전시설은 대부분 경사가 완만한 곳에 집중되어 있었으며, 상당 수의 시설이 도로와 주거지로부터 200m 이내에 분포하고 있었다. 농지 인근에 위치한 태양광 발전시설의 경우에는 농민들과의 갈등을 유발할 수 있으므로 갈등 조정을 위한 체계 정립이 요구된다. 셋째, 전체 태양광 발전시설의 1/4가량이 산지 및 구릉에 위치하므로 홍수 및 산사태 등 자연재해에 대비할 수 있도록 상시적인 모니터링이 필요하며, 특히 산지 환경에 영향을 미칠 것으로 생각되는 유형에 대해서는 환경영향 평가기준에 따른 정기적인 평가가 요청된다. This study analyzed locational characteristics and types of photovoltaic powerplants in Geochang-gun, and derived policy implications and management measures regarding location type, assessing whether they are installed in appropriate locations not causing physical, environmental, and social problems. As a result, the study reached the following conclusions. First, the locations of photovoltaic powerplants could be classified into five types, based on solar radiation, gradient, slope direction, distance from residence, and distance from road. Each type had its own characteristics. Second, most of the photovoltaic powerplants in Geochang-gun were concentrated in gentle slopes, and many of them were distributed within 200 meters from roads and residences. In the case of photovoltaic powerplants located near farmland, it is necessary to establish a system to manage or mitigate issues as they could cause conflicts with farmers. Third, about a quarter of all photovoltaic powerplants are located in mountains or hills, so regular management is needed to prepare for natural disasters such as floods or landslides, and it is necessary to establish its own environmental impact assessment standards. Especially, it is required to regularly monitor the types that are thought to affect the environment of the mountainous area.

There were no statistically significant relation between pulse energy of left Cheok subtracted from left Chon and KI, MRS hot flush score. 2. When divided depending on MRS hot flush score, There were no statistically significant differences on pulse energy. Conclusions: The results suggest that there is no correlation between hot flush score and pulse energy.

Objectives: This study was performed to review the research trends in the periodic therapy of dysmenorrhea in traditional Chinese medicine (TCM). Methods: We searched articles in Chinese Academic journal (CAJ). Search key words were `dysmenorrhea` and `periodic therapy or cyclic treatment`. Results: We selected 6 studies except unrelated studies. According to study design, study was classified into 1 single group before after study and 5 randomized controlled trials. According to dysmenorrheal type, study was classified into 4 studies on primary dysmenorrhea and 2 studies on secondary dysmenorrhea. In the selected studies, there were four studies in which the menstrual cycle was divided into 2 periods, one study divided into 3 periods, and one study divided into 4 periods. The most used herb was “Angelicae Gigantis Radix”, “Cinnamomi Cortex Spissus”. All studies showed effective results on dysmenorrhea. Conclusions: In TCM, Research on periodic therapy of dysmenorrhea was being conducted more actively than Korean medicine. The periodic therapy seems to be effective on dysmenorrhea from this research. It would be necessary to fulfill further clinical study with periodic therapy on dysmenorrhea in Korean medicine to establish standard evidence of them.
