최근 4차 산업 혁명 및 코로나19로 인해 비대면 서비스 시장의 수요가 증가하고 있으며, 전 세계적으로 로봇을 이용한 다양한 서비스들이 개발되고 있는 추세이다. 본 논문에서는 사람 대신 로봇이 테이블 위에 놓인 물체들을 적절한 수거함들로 옮겨 테이블을 정리해주는 지능형 로봇 서비스를 구현함으로 목표로 한다. 효과적인 목표 서비스 개발을 위해, 본 연구에서는 딥러닝 기반의 심층 물체 자세 추정기를 이용해 물체들의 실시간 위치를 파악하고, 시멘틱 웹 기반의 지능형 로봇 체계를 활용하여 작업 환경에서 동적 상황 정보를 추론해낸다. Recently, due to the 4th Industrial Revolution and COVID-19, demand in the non-face-to-face service market has been increasing and there is a trend to develop various useful robot services around the world. In this paper, we aim to develop an intelligent robot service that the robot cleanups a table by picking and placing objects placed on the table into proper bins instead of human users. In order to develop the target service effectively, we use a deep learning-based object pose estimator to find out real-time pose of individual objects, and make use of a robot intelligence framework based on semantic web technology to infer dynamic context from the task environment.

Orthodontic treatment using mini-tube appliances and customized resin domes using 3D CAD design

( Hye-in Kim ),( Sung-hoon Lim ),( Sung-nam Gang ) 조선대학교 구강생물학연구소 2016 Oral Biology Research (Oral Biol Res) Vol.40 No.3

Mini-tube appliances can be used instead of orthodontic brackets and tubes. This mini-tube is a simple tube without a bonding base and bonded to the tooth by covering the tube with flowable resin. It is more esthetic and hygienic, although there is a limitation that only NiTi wires can be inserted into the mini-tube appliance. However, this mini-tube has no pre-adjusted in-and-out compensations, and therefore wire bending is required for finishing. This report describes a Class I crowding case treated with mini-tubes and customized resin domes using a virtual setup, 3-dimensional (3D) computer-aided design (CAD) and 3D printing. By this customization, wire bending or repositioning of mini-tubes was minimized, and treatment was performed with fewer adjustments and increased patient’s comfort.

In an aging society, there is an increasing possibility of the duplication of the drugs given to patients because they take many kinds of drugs. Among the prescriptions given to the patients who was treated at multiple ambulatory clinics in St. Mary's hospital for one month of September, 2002, in which drugs that has identical or similar effects are prescribed, we analysed and evaluated them by patients' characteristics, kinds of medication, severity of side effects on a case by case basis. More, we assessed the potential additional costs. As a result of this study, the duplication rate turned out to be 6.69% and it was shown that the proportion of the elderly patients over 60 was high. The gastro-intestinal medications took up a large part and most of the cases showed that the danger caused by double taking of medicine was slight, but there were some examples in which the serious side effects were predicted. Expected additional costs were the average 11.349 won and it ranges from the minimum of 56 won to the maximum of 135,720 won. In conclusion, the management of drug histories of the patients who need the plural treatments is very important and the necessity of the individual and professional guidance of taking medicines for the elderly patients is emerged, too.

김혜민(Hye-min Kim),김인겸(In-gyum Kim),이대근(Dae-Geun Lee),임병환(Byunghwan Lim),유승훈(Seung-Hoon Yoo) 한국혁신학회 2018 한국혁신학회지 Vol.13 No.2

본 연구에서는 2000년부터 2015년 동안의 분기별 제주도 평균기온, 전력가격, 전력사용량, 소득 자료를 이용하여 제주지역의 전력수요함수를 추정하였다. 내생시차변수모형을 적용하여 시계열 데이터 사용의 효율성을 향상시키고자 하였으며, 계절더미변수를 추가하였다. 분석 결과, 제주지역에 대한 전력수요의 단기 가격탄력성은 –0.72, 단기 소득탄력성은 0.94로 추정되었다. 제주지역의 기온에 따른 연간 전력수요는 많은 선행연구들에서 밝혀진 바와 같이 U자 모양의 2차 함수 모형이며, 제주지역의 전력수요 임계기온은 12.9℃인 것으로 추정되었다. 또한 전력수요의 장기 소득탄력성은 0.91로, 장기 가격탄력성은 –0.59인 것으로 나타났으며, 전력수요의 장·단기 가격 및 소득탄력성 값은 유의수준 1%에서 통계적으로 유의하다. 기온변수를 추가했을 때가 제외했을 때 보다 통계적 설명력과 적합도가 높아지는 것으로 나타났다. quarterly data of average temperature, electricity price, electricity demand, and GRDP in Jeju over the period 2000 to 2015. Lagged dependent variable model and ordinary least square method had been applied as a robust approach to estimating the parameters of the electricity demand function and add seasonal dummy-variable. he results show that short-run price and income elasticities of the electricity demand are estimated to be -0.72 and 0.94, respectively. The relationship between temperature and electricity demand in Jeju is U-shape relationship as many references. And the threshold temperature of electricity demand is about 12.9℃. Also long-run price- and income-elasticities of electricity demand are estimated to be –0.59 and 0.91, respectively. All of results of price- and income-elasticities of electricity demand are statistically significant at the 1% level. The electricity demand in Jeju is in-elastic with regard to price and income changes according to results of this study. It is shown that power of explanation and goodness-of-fit statistics are improved in the use of the lagged dependent variable model with temperature variables than conventional model without temperature variables.

Treatment of Class I crowding using simple tubes bonded with customized resin coverings: A case report

Seo-Rin Jeong,Hye-In Kim,Sung-Hoon Lim 대한치과교정학회 2019 대한치과교정학회지 Vol.49 No.2

As an alternative to the conventional fixed appliance that uses orthodontic brackets, a simple round tube without a bonding base can be bonded to the tooth surface by covering the tube with flowable resin. In this technique, bent wires cannot be inserted into the simple tubes; therefore, repositioning of the simple tubes is often required for adjustments. To reduce repositioning of simple tubes, a dome-shaped resin covering of the simple tube can be designed with a customized in-and-out compensation, using three-dimensional computer-aided design software based on digital simulation of orthodontic tooth movement. In the present case, the use of simple tubes bonded with customized resin coverings in a Class I nonextraction case is described in a 17-year-old male, in whom moderate crowding of the anterior teeth was treated over an 8-month period. This case shows that simple tubes can be used as an alternative to brackets in some Class I nonextraction cases, with the potential benefit of reducing decalcification.

<P>Catalysts for the oxygen reduction and evolution reactions are central to key renewable-energy technologies including fuel cells and water splitting. Despite tremendous effort, the development of oxygen electrode catalysts with high activity at low cost remains a great challenge. In this study, we report a generalized sol–gel method for the synthesis of various oxide nanocrystals (TiO<SUB>2</SUB>, ZnO, Nb<SUB>2</SUB>O<SUB>5</SUB>, In<SUB>2</SUB>O<SUB>3</SUB>, SnO<SUB>2</SUB>, and Ta<SUB>2</SUB>O<SUB>5</SUB>) with appropriate transition metal dopants for an efficient electrocatalytic oxygen evolution reaction (OER). Although TiO<SUB>2</SUB> and ZnO nanocrystals alone have little activity, all the Mn-, Fe-, Co-, and Ni-doped nanocrystals exhibit greatly enhanced OER activity. A remarkable finding is that Co dopant produces higher OER activity than the other doped metals. X-ray photoelectron and X-ray absorption spectroscopies revealed the highly oxidized metal ions that are responsible for the enhanced catalytic reactivity. The excellent OER activity of the Co-doped nanocrystals was explained by a synergistic effect in which the oxide matrix effectively guards the most active Co dopants at higher oxidation states by withdrawing the electrons from the metal dopants. The metal-doped NCs exhibit enhanced catalytic activity under visible light irradiation, suggesting their potential as efficient solar-driven OER photoelectrocatalysts.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jpccck/2015/jpccck.2015.119.issue-4/jp511561k/production/images/medium/jp-2014-11561k_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/jp511561k'>ACS Electronic Supporting Info</A></P>

Background : The cun measurement System, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and Small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height.

임흥빈,김인숙,김혜영,김경희 단국대학교 1999 論文集 Vol.34 No.-

The sample pretreatment technique using an atmospheric pressure acid digestion for the analysis of magnesia that is a representative material for fine refractory was studied. When magnesia was dissolved by four kinds of acids . i. e.. hydrochloric acid, nitric acid, perchloric acid + hydrochloric acid, phosphioric acid + nitric acid, the intensity change of Cr. B. Fe. Ca. Al were observed by ICP-AES. And, the recovery was measured by spiking the standard solution of 100ppm, the results indicate that the loss of most of elements is 8∼32% for hydrochloric acid and 7∼26% for nitric acid. The recovery is relatively lower value compared to that of perchloric acid+hydrochloric acid(1+2) and phosphoric acid+nitric acid(1+2), of which the recovery is more than 95% for most of elements. Magnesia single crystal and powder were quantitatively analyzed by a standard addition method after optimizing in sample pretreatment using HClO4 + HCl.

남인숙,임혜자 韓國舞踊敎育學會 1999 韓國舞踊敎育學會誌 Vol.10 No.2

The purpose of this study was to investigate subjects' mood change after participating dance activity. The mood changes of three groups were measured; (1) hiphop dance group (2) folk dance group and (3) running group. One hundred twenty middle and high school students(male=18 female=102) participated in this study. The subjets' age was ranged from 15 to 18, with the mean age of 16.5. Dependent measures were positive well-being, psycological distree, and fatigue. Mood was assessed immediately pre-and-post dance activity with the SEES (Subjective Exercise Experience Scale). ANOVAs with repeated measure on the last factor was used to analyze the mood changes. The results of this study showed that three groups are significantly different each other. The results are as followed. The hiphop dance group and folk dance group showed higher positive well-being than the running group. The finding suggest that the hiphop is a representative culture of teenager. It is believed that participating in hiphop may induce to incease the teenager's motivation. Therefore it is concluded that dance activity would increase the positive attitude and reduct the negative attitude and fatigue of participants.
