We have studied electro-optic characteristics as a function of passivation thickness existing between common electrode and pixel electrodes in the fringe-field switching (FFS) mode using the LC with positive dielectric anisotropy. A steep increase in the transmission is observed with increase in the passivation layer from $0.29{\mu}m$ to $1.09{\mu}m$ and thereafter it almost saturates over the $1.09{\mu}m$ of passivation layer. This saturation is mainly associated with correlation between transmittance at the center region of pixel electrode and at the center region between pixel electrodes. From the results, optimal thickness of passivation layer can be defined.

Purpose: The purpose of this study is to find out the effects of bisphosphonates (BPs) on the proliferation and the alkaline phosphatase (ALP) activity of human bone marrow derived mesenchymal stem cells (hMSCs), and thus state its correlation with bisphosphonate related osteonecrosis of the jaw (BRONJ). Methods: hMSCs was obtained by collecting and culturing cancellous bone fragments from a patient undergoing iliac bone graft. Alendronate (Aln) and Pamidronate (Pam), Ibandronate (Ibn) were added to the culture media in the concentration from $10^{-3}$ M to $10^{-11}$ M and cell toxicity, viability were measured. For ALP activity evaluation, Aln and Pam were added to the culture media in the concentration from $5{\times}10^{-7}$ M to $1{\times}10^{-8}$ M and were cultured for 1 week, 2 weeks and 3 weeks. ALP activity data were standardized using protein assay. Control groups were prepared for each examination. Results: Aln, Pam and Ibn all failed to increase the proliferation of hMSCs. With 1 week, 2 weeks of $5{\times}10^{-8}$M of Aln treatment, the ALP activity increased. Pam treatment increased the ALP activity with 2 weeks of $5{\times}10^{-8}$ M and$1{\times}10^{-8}$M. Also Ibn treatment increased the ALP activity with 2 weeks of $5{\times}10^{-8}$ M and $1{\times}10^{-8}$ M. Conclusion: It is considered that BPs are not capable of improving the proliferation of hMSCs. Also, after a transient increase in the ALP activity with the lower concentration of BPs, the activity decreased again. Therefore, in patients on long-term medication of BPs, the proliferation and osteoblast differentiation of hMSCs are restrained, and thus delayed wound healing and increase in BRONJ complications may occur.

Cementoblastoma is a benign ectomesenchymal odontogenic neoplasm that forms a mass of cementum or cementum-like tissue continuous with the tooth root. Cementoblastoma represents 1% to 6.2% of all odontogenic tumors, and occurs more than 75% arise in the mandible, with most cases arising in the molar and premolar regions. About 75% arises before the age of 30. Radiographically, it appears as a radiopaque mass with a thin radiolucent rim attached to the roots of a tooth. The recurrence rate is 37% in the current study and cortical expansion and perforation of the cortex are common findings in lesions that subsequently recurred. It is apparent that recurrence rate depends largely on the completeness of removal than any other factor. Here we present a 20 year old, female case of an unusual multiple recurrent cementoblastoma around a previous lesion which had been surgically excised 2 years ago.

BIM 기반의 시공단계 견적데이터를 활용한 일일 진도관리모델 구축 방안

정준호,진상윤,Jung, Jun-Ho,Chin, Sang-Yoon 한국건설관리학회 2011 한국건설관리학회 논문집 Vol.12 No.5

Reliable progress management at construction requires integrated information of cost and schedule, and information is used as a basis for project performance measurement. However, separate handling of cost and schedule information at construction projects makes objective measurement more difficult and decreases management productivity due to additional works for breaking down bill of quantities into corresponding activities. Recently, research related to BIM addresses issues on effective progress management based on BIM with incorporation of daily progress management. Therefore, the objective of this paper is to propose information model for daily progress rate and budgeted cost of work performed by utilizing BTM-based quantity and location information. 건설현장에서 정확한 진도를 관리하기 위해서는 비용정보와 일정정보를 결합한 통합정보가 요구되며 프로젝트의 성과측정을 위한 기초자료가 된다. 그러나 국내 건설공사는 비용과 일정정보를 각각 관리함으로써 객관적인 성과측정이 어려우며 내역서상의 물량을 액티비티에 분개하는 작업을 통해 생산성을 감소시킨다. 한편, BIM을 활용한 연구가 진행되면서 BIM을 통해 보다 효율적으로 진도관리하는 연구가 필요한 실정이며 현장에서는 일일 작업관리에 대한 필요성이 요구되고 있다. 이러한 건설 산업의 흐름에 따라 본 논문에서는 BIM 모델의 위치정보와 BIM기반의 견적데이터를 활용하여 3가지 타입의 진도관리단위를 생성하고 이를 통해 일일 진도율 및 일일 기성액을 파악하는 정보모텔을 제시하고자 한다.

전면 개정되어 2018년 1월 19일부터 효력을 발휘할 미국 인간대상연구 보호를 위한 연방정책(Federal Policy for the Protection of Human Subject)인 커먼룰(Common Rule)은 21세기 들어 변화한 연구환경을 반영하는 동시에 연구대상자를 보다 잘 보호하기 위한 것으로서, 중요한 연구를 촉진하고 연구자의 부담과 지연, 모호성을 줄이면서 동시에 현재의 감독 체제를 현대화하고, 단순화하고, 강화시키는 노력으로 개정 목적을 밝히고 있다. 한국 생명윤리 및 안전에 관한 법률의 구성과 시행에 많은 영향을 미쳐 온 미국 커먼룰의 개정은 향후 한국의 연구대상자 보호 정책에도 많은 변화가 필요함을 시사하고 있다. 본 연구에서는 2017년 미국 커먼룰 개정을 중심으로, 미국 커먼룰 제정과 변천 과정을 인간대상연구윤리 관점의 시대적 변화라는 역사적 맥락에서 살펴보고 현재의 커먼룰 개정이 인간대상연구 환경의 변화를 어떻게 반영하고 있는지 보이고자 한다. 이를 통해 한국 생명윤리법 제정과 및 시행 과정에 많은 영향을 미쳐온 커먼룰의 고유한 맥락을 이해하고, 연구대상자 보호와 인간대상연구의 개념 변화의 의의에 대해 논의해 보고자 한다. Fully revised and updated U.S. Common Rule (Federal Policy for the Protection of Human Subject) will come into effect from January 19, 2018. Updated Common Rule reflects the changes in research landscape, as well as public view of human subject research. Purpose of the revision is to modernize, strengthen, and make more effective policy. It is intended to facilitate valuable research, reduce burden, delay, and ambiguity for investigator while better protecting human subject involved in research. Changes in its scope and definitions of Common Rule suggest that Bioethics and Safety Act in Korea may also need substantial revision which can reflect the current shifts in research enterprise. This study focuses on historical development of the Common Rule, and significant changes from pre-2018 rule in the final rule (2017) of the Common Rule which shows changing concept of human research protection. This will help to understand the context of development process of Common Rule that had substantial influence on Korea’s Bioethics and Safety Act.

The purpose of the study is to investigate the effect of a simulation training of BLS in paramedics in pre-hospital situation. This a nonequivalence control quasi-experimental study. The study subjects were 8 paramedics of experimental group and 8 paramedics of control group in K fire department. An informed consent was written by the subjects after explaining of the purpose of the study. The study methods consisted of conventional education and practice training. The conventional education was done for 30 minutes and the practice training was taken by four trainees of one group and the instructor demonstrated Basic Iife Support (BLS) performance for three minutes. Each trainer peformed BLS for ten minutes. In the beginning of the course, two paramedics got off from the ambulance and performed BLS including 5 cycles of Cardiopulmonary Resuscitation (CPR). Soon after the BLS, another two paramedics performed pre-hospital BLS survey. The education was guided by two professors of emergency medical technology, two Basic Iife Support instructors, and two emergency rescue directors. Pre-hospital BLS was measured by a 5-point Likert scale. Higher score means higher performance skills. The data were analyzed using SPSS/WIN 22.0 program set at significance level of p<05. The effect of simulation education was much more significant than the conventional education in BLS. The simulation education is very important and effective in improving the clinical performance skills of paramedics than the conventional education. The simulation education can provide the virtual environment of cardiac arrest to the paramedics. In conclusion, the simulation education can provide the effective teaching methods for various practice performance skills and solution by critical thinking in the paramedics and healthcare providers in the future.

근육분절검사를 위한 관절운동 계측자동화 장치 및 MMI 개발

정준호(Jun-Ho Jung),최광호(Kwang Ho Choi),김동헌(Dong Hun Kim) 한국지능시스템학회 2021 한국지능시스템학회논문지 Vol.31 No.2

본 논문은 신경학적 검사 중 근육분절 검사인 근력검사를 정확한 수치로 검사하기 위하여 관절운동 계측 자동화 장치와 사용자 인터페이스를 위한 MMI(Man Machine Interface)를 제안한다. 근육분절 검사란 척수신경에 연결된 근육 집단을 검사하여 어떤 신경이 손상이 되었는지 확인하는 것이다. 근육분절 검사는 지금까지 의료진의 육안과 손을 통한 검사를 통하여 검사 차트에 손상 정도를 기록하여 왔다. 이러한 검사는 의료진의 판단에 따라 검사결과가 달라지기 때문에 객관적으로 판단하기 어렵다. 이러한 문제점을 해결하기 위하여 본 연구에서는 로드셀 센서를 사용하여 근육분절 검사 시 측정되는 힘의 크기를 실시간 그래프로 보여주고 측정된 데이터를 RMS 값으로 계산하여 하나의 수치로 나타내어 정량화 하는 것을 제안한다. 또한 근육분절 검사 시 측정값에 칼만 필터를 적용하여 사람 또는 하드웨어에서 발생하는 잡음을 필터링하여 정확한 데이터를 보여준다. 근육분절 검사를 위한 사용자 인터페이스는 비주얼 스튜디오의 C#을 사용하여 제작하였고 MS ACCESS를 활용하여 환자의 개인 정보를 측정된 실시간 그래프와 함께 관리하였다. 제안한 자동화 장치는 검사의 신뢰도를 높여주므로 신경과, 신경외과, 정형외과, 재활의학과에서 유용하게 사용될 수 있다. This paper proposes an automation of joint motion instrumentation and its MMI(Man Machine Interface) for user interfaces to examine muscle strength tests. A muscle segmentation test is to examine the muscle groups connected to the spinal cord to determine which nerves have been damaged. Muscle segmentation tests have so far recorded the degree of damage on the examination chart through visual and hand examinations by medical staff. Such tests are difficult to judge objectively because the results of the tests vary depending on the judgment of the medical team. To solve these problems, this study proposes using load cell sensors to show the magnitude of the force measured during muscle segmentation tests in real time graphs and to quantify the measured data by computing it as an RMS value and representing it as a single numerical value. In addition, during muscle segmentation tests, a Kalman filter is applied to reduce the noise generated by people or hardware to show accurate data. The user interface for muscle segmentation testing was created using the Visual Studio"s C# and used MS ACCESS to manage patients" personal information with measured real-time graphs. The proposed automation device increases the reliability of the examination, which can be useful in neurology, neurosurgery, orthopedic surgery, and rehabilitation medicine.

This study is to compare cognition for Taekwondo Poomsaecompetition between referee and athlete, and to suggest basic data in order for introducing Taekwondo Poomsae athlete and expanding the base via effective game operation of referee and transparent judgment. To achieve the goal described above, a survey targeting to Poomsae referee and athlete has been conducted (from 2013 Aug to Sept) by 3 auxiliary researchers. The survey, which was followed by explanation on this research, was conducted on the basis of Self-administration. First, most objects (referees and athletes)selected 'Generally fair'in questionfor fairness of judgment. And 'Referee's qualification' was pointed out by most referees asa reason of unfairness made by referee's Poomsae judgment, while 'Personal relationship' and 'Referee's qualification'were pointed out bymost athletes as the reason. Meanwhile, 'Very good' was selected by most referees for the judgment in comparison with the past (about 5 years ago) judgment, while 'Generally improved' was selected by most athletes. There was no statistically significantdiscrepancy in cognition for fairness between refereeand athlete. Second, 'Generally reliable' was selected by most objects (referee and athlete) for the question of reliability, showing no statistically significant difference between two groups. And 'Athlete' was pointed out by most objects (referee and athlete) as the group having the lowest reliability in terms of referee's judgment, showing statistical difference in significance level (x2 =14.541, p<.01). When it comes to question asking'If referee is admirable', most objects selected 'Generally yes', showing statistical difference in significance level (x2=9.715, p<.05). Third, for cognition of referee and athlete for misjudgment, most referees selected 'Often', while most athletes answered 'Not often', showing statistical difference in significance level (x2=11.451, p<.05). For the frequency of intentional misjudgment made by Poomsae referee, most athletes selected 'Not often', while most referee selected 'Rare', showing statistical difference in significance level (x2=26.492, p<.001).In comparison of cognition about 'Whether judgment can be reversed due to intentional misjudgment or mistake', most referee answered'Generally yes', while most athletes selected 'Not many', showing statistical difference in significance level (x2=25.893, p<.001). Fourth, when it comes tocognition of referee and athlete for factors affecting judgments, most referees pointed out 'Referee's qualification' as the obstacle for enhancing referee's judgment, while most athletes selected 'Personal relationship', showing statistical difference in significance level (x2 =23.041, p<.001). In addition, 'General' was selected by most objects (referee and athletes) as biased judgment, showing statistical difference in significance level (x2=13.730, p<.01). For the resolution to eliminate mistrust among referee and athlete, 'Fair judgment of referee' was selected by most referees, while 'Understanding each other in different point of view' was selected by most athletes, showing statistical difference in significance level (x2=28.933, p<.001). Fifth, as an improvement plan for Poomsae competition, most objects (referee and athlete) answered that 'Current method is reasonable', showing no statistical difference in significance level (x2 =28.933).As an important factors for improving fairness in judgment of referee, most objects (referee and athlete) selected 'Referee's qualification',showing statistical difference in significance level (x2=35.870, p<.001). When it comes to requirement which has to be possessed by referee, most objects (referee and athlete) pointed out 'Effort to judge in fairness', showing no statistical difference in significance level (x2=16.349, p<.001). And, for question asking required policy, most objects (referee and athlete) choose 'Post-competition referee judgment system', showing statisti
