The first Cybathlon will be held in October 2016 and this contest is designed for developing prosthetic technologies. In this study, we analyzed the Cybathlon and from this analysis we researched advanced prosthetic technologies. In addition, we ascertained some ethical issues about post-human beings with prosthetic equipment, which could rehabilitate disabled people and even serve to enhance non-disabled people. Disability is only one of the inconveniences that a person must endure, but everyone has some sort of inconvenience to endure. We found the possibilities of dissolving boundaries between people with disabilities and their able-bodied counterparts through the Cybathlon and prosthetic devices. The features and role of our body itself will be expanded with the help of these future technologies. Engineers, inventors and designers are making better prostheses for disabilities, but these could help not only disabled people but also every non-disabled people. The dominant ethical debates that appear in bioethics and human- related enhancement are reliability, authenticity and autonomy. Reliability and autonomy are the question of being safe and controllable. In this study, we want to raise a question on authenticity: ‘if a person with a powered-prosthesis sets a better record, should we admit it?’

국내 무단횡단 사고 발생건수는 2014년 4,093건에서 2016년 5,761건으로 계속 증가하고 있다. 이러한 추세는 무단횡단이 또 하나의 사회문제로 떠오르고 있음을 의미한다. 이 연구에서는 이러한 무단횡단 사고가 자주 발생하는 장소를 찾고 그 특징을 분석하여 무단횡단 사고를 예방하기 위한 방안을 제시하고자 한다. 이를 위해 도로교통공단의 TAAS교통사고정보 개방시스템에서 제공한 서울시 보행자 무단횡단사고 데이터를 QGIS의 포인트 매핑(Point Mapping) 및 커널밀도 추정법(Kernel Density Estimation)으로 무단횡단 핫스팟 분석을 실시하였다. 분석결과, 핫스팟 지역으로 선정된 곳은 종로구, 영등포구, 구로구, 중구의 일부 지점으로서 높은 밀도의 핫스팟 그리드를 가지고 있었으며 그 지역을 중심으로 무단횡단 핫스팟 군집을 형성하고 있었다. 이 지점들은 대개 지하철역과 버스정류장과 같이 교통량이 많고 인구이동률이 높은 장소에 분포하고 있었으며 재래시장과 같은 상업시설이 분포해 있었다. 또한 핫스팟으로 선정된 지역에서는 중앙선 및 도보 펜스가 부재하거나 파손된 경우가 많았다. 이 연구는 이러한 무단횡단 핫스팟 분석을 바탕으로 상황적 범죄예방(Situational Crime Prevention) 전략을 통해 무단횡단 발생을 예방하는 방법을 탐색하였다. Domestic jaywalking accidents are continuously increasing from 4,093 cases in 2014 to 5,761 cases in 2016. This trend implies that the jaywalking is emerging as another social problem. In this study, we propose a method to prevent a jaywalking accident by searching for a place where such jaywalking accident happens frequently and analyzing its characteristics. For this purpose, jaywalking hotspot analysis was carried out using the point mapping and kernel density estimation methods through the QGIS using pedestrian jaywalking incident data provided by TAAS traffic accident information opening system of Road Traffic Corporation. As a result of the research, the hotspot areas in Jongno-gu, Yeongdeungpo-gu, Guro-gu, and Jung-gu have high density hotspot grid and they formed an jaywalking hotspot cluster around the area. These areas were mostly located in high traffic areas such as subway stations and bus stops, and high population moving places and commercial facilities such as traditional markets were distributed. Also, in the areas selected as hotspots, the center line and the walking fence were often absent or damaged. Based on the analysis of the jaywalking hotspots, situational crime prevention strategies were sought to prevent the occurrence of jaywalking.

Until recently, colorectal polyps were classified predominantly as hyperplastic or adenomatous. While adenomatous polyps are well-characterized precursor lesions of adenocarcinomas, hyperplastic polyps have been considered as benign lesion. However, some hyperplastic polyps with serrated morphology of the crypts have been recognized to have distinctive features and these polyps were termed ‘serrated adenomas’. Recent data show that sessile serrated adenomas (SSA) might be the precursors of serrated colonic cancers, underlining the necessity of identifying them. SSA is approximately 3% of all polyps, commonly appears as flat or sessile and yellowish due to mucus production. In the pathogenesis of SSA, progression to high grade dysplasia or early invasive carcinoma may be associated with serrated neoplasia pathway different from adenoma-carcinoma sequence. We report a case with a colon polyp diagnosed as sessile serrated adenoma with high grade dysplasia after endoscopic submucosal dissection.

Objectives:This study was to identify weight & metabolic changes in first-episode psychotic patients with antipsychotics use and investigate the differences of weight & metabolic changes between first-episode psychotic patients and controls with antipsychotics use. Method:In this retrospective study, twenty eight first-episode psychotic patients and twenty eight controls with schizophrenia, schizoaffective or bipolar disorder defined by DSM-IV criteria were included. Information about demographic and clinical characteristics of the subjects was gathered from the medical records. Also body weight, sBP, dBP, fasting glucose, lipid profile and WBC count were evaluated before and after antipsychotics use. Rogistic regression was conducted to assess factors associated with weight gain. Results:First-episode psychotic patients showed more weight and BMI changes than controls after antipsychotics use, and these changes continue over 12 months. On the other hand, there were no significant factors associated with weight gain. Conclusion:The results of present study suggest that antispychotics is one of the major causes inducing weight gain of psychotic patients and antipsychotics-induced weight gain is more vulnerable to drug-naive first-episode psychotic patients.

The SBR(Sequencing Batch Reactor) process is ideally suited to treat high loading wastewater due to its high dilution rate. SBR operates by a cycle of periods consisting of filling, reacting, settling, decanting and idling. The react phases such as aeration or non-aeration, organic oxidation, nitrification, denitrification and other biological reactions can be achieved in a reactor. Although the whole reactions can be achieved in a SBR with time distributing, it is hard to manage the SBR as a normal condition without recognizing a present state. The present state can be observed with nutrient sensors such as NH₄^(-)-N, NO₂^(-)-N, NO₃^(-)-N and PO₄^(3-)-P. However, there is still a disadvantage to use the nutrient sensors because of their high expense and inconvenience to manage. Therefore, it is very useful to use common on-line sensors such as DO, ORP and pH, which are less expensive and more convient. Moreover, the present states and unexpected changes of SBR might be predicted by using of them. This study was conducted to get basic materials for making an inference of SBR process from ORP(oxidation reduction potential) of synthetic wastewater. The profiles of ORP, DO, and pH were under normal nitrification and denitrification were obtained to compare abnormal condition. And also, nitrite and nitrate accumulation were investigated during reaction of SBR. The bending point on ORP profile was not entirely in the low COD/NOx ratio condition. In this case, NOx was not entirely removed, and minimum ORP value was presented over -300mV. Under suitable COD/NOx ratio which complete denitrification was achieved, ORP bending point was observed and minimum ORP value was under -300mV. Under high COD/NOx ratio, ORP bending point was not detected at the first subcycle because of the fast denitrification and minimum ORP value was under -300mV at the time.

The corrosion behavior of copper in neutral aerated synthetic tap water was investigated using electrochemical methods, SEM and XPS. All potentiodynamic polarization curves showed active corrosion behavior, and the corrosion rate was more sensitive to flow velocity than Cl^(-) ion concentration and temperature. The result of potentiostatic test indicated that the current density decreased with increasing time regardless of Cl^(-) ion concentration and temperature in stagnant condition because copper compounds were formed uniformly on the surface. The EIS plot was changed from two time constants to three time constants with the formation of Cu₂O, and the charge transfer resistance (R_(ct)) was very large and increased with increasing immersion time. From all results, copper had good corrosion resistance in this potable water system.

The study is tried to look for the quantitative approach to Budgeting-Making the public sector and to be classified roughly Budgeting-Making into three fields private, city-government and federal government. The generalization of the approach is to be construed with traits and common features of each fields that are to be traced on three fields. The budget would be the combination between scarce resources and limitless desires and so the budged is the product of Politics. The study is to adjust the focus of the possibility which in forming the produce would be available to make it scientific to pool all social powers and represent social equality and values. The quantification sometimes loses sight of the nature of the subjects and will become to be a parochial, but the substance of the quantification would be criteria which leads to explain in more detail lots of phenomena and to guide the settlement and then it would not be far from a science. The quantitative approaches are consisted of two demensions-one is micro and other macro. Two demensions are reciprocal in nature and according to objects they will be applied to each other. Incrementalism is based on the approach and in fact it would be criticized as actualistic, negative or satisfied, but only the contents and the effects of the budget could be so. The nature of the budget is concentrated on its effectiveness and results than actualistic or negative. The quantitification of the budget therefore could accelerate that the budget is to be a science and could bring it to be scrutinized. The quantification could not mean the sole-equation but could come multi-demensionals and a complex of all elements to be simple and warm.

T. Y. SHIM, S. H. SHIN, S. I. OH, J. I-. MUN. EMG Analysis for Investigation Muscle-Collaborated Relationship during Golf Swing. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 177-189, 2004. Kinematic and kinetic analysis using 3D Motion Capture system are common, yet there is little in the literature that discuss the relationship and coactivity between muscles during the golf swing. The purpose of this study was to describe the relationship between the employed 16 muscles during golf swing. We could observe 3 muscle patterns such as 'Line' shape, 'L' shape, and 'Loop' shape for the golf swing activity. The 'Line' shape indicates that two muscles act almost perfectly in phase, and the 'L' shape represents that two muscles act in a reciprocating manner(When one is active, the other is quiescent and vice versa). And the 'Loop' shape indicates that two muscles act sequently(After one is active, the other act). In these results, we knew the muscle patterns during golf swing is similar to the patterns during gait. And we presented it was possible to show the consistence of golf swing through the frequency analysis of muscle patterns. We believe that the results potentially useful for the golf players and coaches to analyze their performance.

The connected components algorithm is one of the techniques used to divide a binary image into regions and to assign unique number into connected regions. In this paper, a fast connected components algorithm based on chain codes is proposed. The algorithm uses look-up table based on parity checking of the contour. We proposed the new look-up table which can separate starting, ending and ignore points. In addition to the algorithm can be applied to extract chain codes form binary images and restore the image form chain codes. Comparison of the proposed method and ones existing method are provided.
