New ITO thin film of good performance has been developed by brand-new, plasma-damage-free sputtering process at the room temperature. The room temperature-processed ITO films with optimized conditions as neutral beam acceleration bias of -30V and In & Sn composition ratio of 99:01 gives lower resistivity as $4.22{\times}10^{-4}{\Omega}-cm$ and higher transmittance over 90% a wavelength of 550 nm. The transmission electron microscope (TEM) images of the films show a nano-crystalline structure.

CO2 emission makes up more than 80% of whole green gas. Therefore CO2 is recognized as the main culprit of global warming. IPCC (Intergovernmental Panel on Climate Change) is advising the 3 methods measuring CO2 emission. TIER1 is measured CO2 emission by criteria the energy consumption, TIER2 measure by criteria the emission factor according to the emission control technique each kind of vehicle, TIER3 is measured by criteria the distance each kind of vehicle. Currently, the most of CO2 emission measurement is used by TIER1. But it is not standardized that CO2 emission measurement method have the factor as work condition each distance. Specially, it is not suggest that methodology has the condition changing load of equipment according to site condition and the same position work as construction equipment. So, this study is suggested the CO2 emission measurement methodology of construction equipment.

Objectives: Recently, many studies have reported beneficial effects from the application of laser and light-emitting diode (LED) therapy for cerebral nervous disease. Transcranial laser therapy and LED therapy may be an effective method to treat diseases of the cerebral nervous system. This study aims to discuss the possibility of laser and LED therapy for cerebral nervous disease by reviewing literature about its effectiveness. Methods: We searched papers using PubMed, Science Direct, CINAHL, KTKP, Oasis and NDSL, using the keywords "Laser therapy, low-level", "Transcranial laser", "Transcranial light emitting diode" and "stroke", "traumatic brain injury", "dementia", "anxiety", "cognitive", "emotional effects", "psychiatric disorder", "multiple sclerosis", "Parkinson's disease". The search range included randomized controlled trials (RCTs) and clinical case series. Reviews and animal experiments were not included. Studies not matched with inclusion criteria were excluded. Results: A total 1,119 studies were found. 1,100 were excluded from scanning titles and abstracts and finally 9 articles were selected. Among the 9 articles, 5 were RCTs, one was a controlled study, and the other 3 were case reports. They reported that transcranial laser therapy and LED treatment had beneficial effects from photobiomodulation to the cerebral nervous system. Clinical evaluation factors showed favorable trends. Conclusions: Transcranial laser therapy and LED therapy seem to be effective to the cerebral nervous system and they may be a favorable choice for cerebral nervous disease.

The purpose of this review was to identify research trends in acupuncture training systems and models and to analyze acupuncture training using phantom models. Articles on acupuncture training were retrieved from domestic and foreign electronic databases (PubMed, CNKI, CiNii, NDSL, KISS, RISS and KMBase). The search included studies conducted from January 1, 2010 to October 1, 2021. Acupuncture training was analyzed by categorization into acupoint location training and needling training. Acupuncture training was most frequently studied in China, acupoint location training was the most studied in 2012, and needling training was the most studied in 2013 and 2020. Among them, a silicone model with a sensor was used for training in acupoint location, and silicone and agarose gel were frequently used for needling training. Classifications of the phantom models for needling training by topic included phantom development, phantom-based education and evaluation system, phantom-based quantitative measurement, comparison of kinematic characteristics of hand motion between experts and beginners, and phantom models for acupoint location and needling training. Further research on the development of acupuncture practice training systems to improve practical skills is needed.

Advent of Wireless Sensor Networks (WSN) has provided potentials to a variety of construction applications. It is well appreciated that WSNs have advantages over traditional wired system, such as ease of installation and maintenance with increased cost savings and efficiencies. However, the obstruction of wireless signal from physical objects in the heterogeneous construction environment often brings challenges to WSN measurement system. This paper analyzed the obstruction characteristic of construction environment where construction materials, equipment, and built structures obstruct the wireless signal yielding negative effect of measurement system. By adopting evaluation criteria, such as packet reception rate, field experiments have been implemented to quantitatively identify the interference of wireless signal from penetration, reflection, and network traffic under the construction environment. The results show that reliable performance of wireless sensor in construction environment depends on the optimal separation distance between a receiver and a transmitter, obstruction types, obstruction thickness, and transmission interval. In addition, the methodology and experimental results of this paper could be used in the practical design of network topology when hundreds of sensor nodes form a mesh network in the large scale construction applications.

Objectives : The purpose of this study is to examine the effect of Juglandis Semen Herbal Acupuncture Therapy on Chronic Shoulder Pain. Methods : Clinical studies on shoulder pain were carried out on 34 patients who were treated at Department of Acupuncture & Moxibusition, Samse Oriental Hospital from June 1, 2009 to October 15, 2009. Subjects were divided into two groups: Experimental group(Group A, n=17) and Control group(Group B, n=17). Group A were treated by common acupuncture therapy, cupping therapy and Juglandis Semen Pharmacopuncture Therapy and Group B were treated by common acupuncture therapy & cupping therapy. All patients in both groups were treated three times a week over 3 weeks. For evaluating change of pain, we used Shoulder Pain and Disability Index(SPADI), Visual Analogue Scale(VAS), Degree of feeling inconvenient in everyday life and Degree of subjective symptoms of shoulder pain. Evaluations were made at baseline and after one week, two weeks and three weeks of treatment. Results : Both group showed chronic shoulder pain decrease after 3 weeks of treatment. But Group A showed better effect on decreasing SPADI, VAS, Degree of feeling inconvenient in everyday life and Degree of subjective symptoms of chronic shoulder pain than Group B. Conclusions : According to the above-mentioned results, it seems that Juglandis Semen Pharmacopuncture Therapy could be applied as the effective method for reducing shoulder pain.

Electric transmission lines pass through a variety of area. Foundation supporting the conductors and tower are selected properly in accordance with external load, for example dead load, wind load, snow load, construction load etc, and topography and geology condition. Typical types of foundation are as follows: pad foundation for small load and hard soil or rock in mountainous area, pile foundation for medium or large load and soft soil in plain field area. This paper introduced cylindrical foundation design & construction for large load and mountainous area. This foundation failure mode against pulling-out show splitting failure by tensile force toward circumferential direction.

수자원 시스템 거동예측은 수문학적 지속성여부에 대한 판단이 선행 되어야 하며 가용한 시계열자료에 대한 추계학적 분석을 통하여 실시하여야 한다. 본 연구에서는 계절형 ARIMA모형을 통한 안동댐 유역의 강우량, 증발산량 및 유출량 시계열자료를 예측함에 있어 전형적인 Box-jenkins의 방법을 따랐고 모형의 식별, 추정, 검진의 3단계를 거쳐 모형화 하였다. 최적 수문시계열 예측 모형을 통하여 안동댐 유역의 강우량, 증발산량 및 유출량 시계열자료로 월별 수문시스템 거동을 예측하였으며, 예측된 결과를 토대로 TANK모형과 ARIMA+TANK결합모형에 의한 장기유출모의를 실시하였다. 분석결과 관측자료의 특성을 비교적 잘 반영 하였으며, 댐 유입량 예측을 위한 추계학적 결합모형의 적용가능성을 검토하였다. 이는 유출량자료의 보유년한이 짧은 대상유역에 월강우량과 증발산량자료 등의 수문시계열 인자 예측을 통한 유출을 모의함으로서 수자원의 중 장기 전략수립에 도움을 줄 것으로 사료된다.
