The establishment of an optimal and functional condylar position (centric relation) as the therapeutic and diagnostic reference position during occlusal treatment for patients with temporomandibular joint and muscle pain. dysfunction has long been an important subject in dentistry. The objective of this study was to compare the reproducibility md the changes of condylar position in normal group to those in patient group after use of the occlusal biteplane splint. For this study, 11 normal adults who had no symptoms of masticatory dysfunction and 18 patients who had visited at the department of occlusion in dental infirmary of Yonsei University were selected. For each subject three centric relation records were recorded before treatment, after 2 weeks and after symptoms were improved. And the condylar positions in centric relation were measured using articulators and a Vericheck. On the basis of this study, the following results were obtained. 1. In normal group, there was no significant difference of reproducibility in condylar position before and after the use of the occlusal biteplane splint for 2 weeks. 2. In patient group there was significant improvement in the reproducibility of condylar position after treatment (P<0.01). The reproducibility in patient group, however, was less than normal group. (P<0.01) 3. The mean distance of condylar movements was $0.38{\pm}0.22mm$ after 2 weeks in normal group. 4. In patient group, condylar movements were $1.36{\pm}0.70mm$ (P<0.01), significantly different from normal group. (P<0.01) 5. In patient group, the main direction of condylar movements after treatment was toward anterior and superior, preponderance being at superior direction.

The antiradical property of hot water extract from dried radish (DR) or dried radish roasted with pressure (DRRP) was investigated in vitro and in LLC-PK1 cell system. The contents of total free amino acid and reducing sugar in DR were decreased by 72.86% and 3.17%, respectively, after pressurized roasting. In vitro test, IC50 for DR and DRRP for DPPH radical scavenging activity were 646.70 and 135.45 μg/mL, 896.10 and 566.98 μg/mL for superoxide anion radical, and 722.26 and 531.84 μg/mL for hydroxy radical, respectively. The radical scavenging effects of DRRP was significantly greater than those for DR (p<0.001). These radical scavenging effects of DR and DRRP were confirmed in LLC-PK1 at which oxidative stresses were induced by superoxide, nitric oxide and peroxynitrite generated in the treatment of pyrogallol, SNP, and SIN-1, respectively. Cell viability was increased in the presence of DR or DRRP, dose dependently (p<0.05), and TBARS formation was decreased. The protective effects of DRRP against oxidative damage in LLC-PK1 were greater than those of DR at the same concentration tested (p<0.05). This superior antiradical activity of DRRP might be due to the products produced during the pressurized roasting in addition to the anti oxidative compounds originally present in the radish. 5-hydroxyl methyl furfural (5-HMF) known as an intermediate product of the maillard reaction was detected in DRRP (0.57 mg/g), but not from DR. In conclusion, daily consumption of DRRP may prevent oxidative damage by retarding oxidative stress.

무말랭이 및 가압볶음 무말랭이 열수 추출물의 항산화 효과를 in vitro와 LLC-PK₁ cellular system에서 살펴보았다. 무말랭이 열수 추출물과 가압볶음 무말랭이 열수 추출물의 라디칼 소거능을 IC??로 비교해 보았을 때 DPPH(646.70 vs 135.45 ㎍/mL), superoxide anion(896.10 vs 566.98 ㎍/mL) 및 hydroxyl radical(722.26 vs 531.84 ㎍/mL)에 대한 가압볶음 열수 추출물의 효과가 유의적으로 높은 것으로 나타났다(p<0.001). 이러한 유리기 소거효과는 LLC-PK₁ cell에서 pyrogallol, SNP 및 SIN-1 처리로 superoxide, nitric oxide 및 peroxynitrite를 생성하여 산화스트레스를 유발한 다음 무말랭이 및 가압볶음 무말랭이 열수추출물을 첨가하였을 때 농도 의존적으로 세포생존율이 증가하고, 과산화물 생성량이 감소하여 세포손상을 보호하는 효과가 관찰되었다. 가압볶음 무말랭이 열수 추출물의 산화손상에 대한 보호 효과는 무말랭이 열수추출물에 비해 모든 유리기에서 유의적으로 높았다(p<0.05). 이러한 무말랭이 열수추출물의 항산화효과는 무에 함유되어 있는 함황 물질, 유리아미노산, 배당체 등에 의한 것으로 생각되며 가압볶음 무말랭이 열수 추출물의 효과가 더 높은 이유는 무말랭이에 함유된 유효성분이 가압볶음에 의해 증가되고 더불어 볶음과정 중에서 생성된 maillard 생성물의 항산화성 때문으로 생각된다. 무말랭이의 환원당 및 유리아미노산 함량은 볶음 후 유의적으로 감소하였으며(p<0.05), 이에 반해 maillard 생성물의 중간산물인 5-hydroxymethyl-2-furfural(5-HMF) 함량은 무말랭이 열수 추출물에서는 검출되지 않았던 것이 가압볶음 무말랭이 열수 추출물에서는 0.57 ㎎/g이 측정되었다. 본 연구 결과가압볶음 무말랭이 차의 섭취는 체내 유리기에 의한 산화적 손상을 보호하는 효과가 높은 것으로 사료된다.

N/A Behaved an experiment changing most suitable aeration/non-aeration operating condition for nitrogen and phosphorus removal of low concentration wastewater in sequencing batch reactor of media and electrolysis apparatus. Result is as following. Organic matter removal more than 90% was seen in Run A, B. D, E and a little low removal by microbial secession was seen in Run C in media sticking and an experiment reactor that do not attach, and Run F was looked inclination that is fallen by subordinate increase. When it is each 42.3%, 38.1%, attached-growth in T-N and RUN A that is floating growth formula in T-P removal, more High removal was seen by 66.1%. 50.0% in Run D. T-P removal in Run E appeared highest by 54.2%. and operating hours was ON 90/OFF 30 minutes. Most suitable driving condition increases inflow quantity by 2 times deciding by Run D and was expose that when drove, removal of T-N, T-P becomes low by each 48.15, 30.8%. High removal more than 92% was seen from all reactors without correlation with voltage and effective surface area from reactor that attach electricity cracker. Effective surface area appeared that occasion removal that effective surface area is small by 61.3%. 65.5% from Run 3, 4 that High removal was seen, and reduces effective surface area by 1/2, 1/4 as T-N removal increases voltage by each 73.3%, 75.1%. 79.2% from Run 1, 2, 3 that is same and differs tension is low. In case T-P removal is high voltage by each 78.4%, 84.3%, 87.7% from Run 1, 2, 3, High removal was seen, and when reduces effective surface area, was shown removal that is low by each 71.7%. 64.6% from being Run 4. 5. Is thought that such result originates that cohesion adsorption of Fe ion and phosphorus compound is high as effective surface area is big as voltage is high. So that High T-P removal more than 80% is seen in P a load factor 0.9 T-P mg/Fe cm/day about Fe effective surface area, tension appeared that 3V is optimum voltage.

N/A Flow and water quality was investigated to the separated and combined sewer pipeline for calculation of infiltration and inflow in the Gwangju city and the result is as follows. Flow change appeared changelessly in Pungam site by separated sewer system. Rainfall augmentation by inflow was seen at rainfall from Sangmu site. This is considered for cause of wrong conjunction and construction the sewer pineline. Watched that influent of continuous infiltration/inflow is the combined system in Songam site. Specially, sudden flow rise was seen at rainfall. The high occurrence amount was seen after cooking time of morning and evening on flow change by time from each investigation site. High concentration was seen most for cooking time of morning and evening on concentration by time. If time passes while BOD concentration by initial rain appeared very high at rainfall, tendency that concentration becomes low slowly was seen. Ratio of infiltration/inflow appeared low in Sangum, Pungam, Bonchon site by water consumption estimation, but high ratio was seen by 53.15%, 60.19% in Songam site. Average, lowest flow and water quality evaluation method for the infiltration/ inflow quantity seemed little except Songam site. Despite Sangmu, Pungam, Bonchon site is lowest low flow in work lowest flow evaluation method, because lowest BOD concentration is high, is considered unreasonable application of infiltration/ inflow quantity. Is considered that it is desirable to use method of average-1 in Sangmu, Pungam site in estimation of infiltrationhflow at dry season of each investigation point. Is considered that it is right to calculate infiltration/inflow because Bonchon, Songam site uses average-2 methods. Infiltration/inflow of collected area appeared high in large area as rainy season. But, collected area appeared low at small agency.

자율주행자동차의 등장에 따라 운전자의 패러다임은 변화하고 있다. 기존의 운전자는 오로지 사람만이 가능한 영역이었다면, 스스로 주행할 수 있는 자율주행자동차의 등장을 통해 자율주행자동차도 운전자가 될 수 있다. 이미 미국과 같은 몇몇 나라에서는 자율주행자동차가 운전자가 될 수 있음을시사하고 있으며, 국내에서도 자율주행자동차 개발과 더불어 자율주행자동차의운전자 재 정의를 실시하려 하고 있다. 이러한 연구 동향에 따라 본 논문에서는 자율주행자동차가 운전자가 되기 위해필요한 요건을 주장하고자 한다. 기본적으로 사람이 운전을 하기 위해서는 인지, 판단, 제어의 세 가지 요소를 갖추어야 한다. 자율주행자동차도 마찬가지로 사람의 운전 메커니즘과 같기 때문에, 운전을 하는 운전자가 되기 위해서는 인지, 판단, 제어의 세 가지 요소를 가지고 있어야 한다. 이제 자동차 운전자는 과거처럼 책임자를 내포하는 개념으로 접근해서는 안 된다. 이제는 운전자를 실질적인 운전을 하는 것으로 규정해야 하며, 책임을 지는것은 책임자를 따로 두어야 한다. 따라서 본 논문이 기초가 되어 관련 연구들이활발히 이루어지기를 바란다. The paradigm of driver is changing to the advent of the self-driving car. The existing driver was only people but the self-driving car will be eligible to become the driver because of the appearance of the self-driving car. Already, Some countries like the United States suggest that self-driving cars can become drivers, and Korea is trying to redefine the signification of the driver with the development of self-driving car. According to research trends, This paper suggest necessary the requirements for self-driving car to become driver. Basically, The driver at the human must have three elements that is cognition, judgment and control. The self-driving car must have three elements that is cognition, judgment and control. Because, Driving mechanism of human is same driving mechanism of Self-driving car. Now, The driver should not approach to the concept of the person in charge as in the past. The driver should be defined as actually driving something, and the responsibility should be set a person in charge. Therefore, It is hoped that this paper will be base and the research of the self-driving car will be actively carried out.
