The fatigue behavior of thermal butt fusion in safety class III high-density polyethylene (HDPE) buried piping for nuclear power plants was investigated using load-controlled bending fatigue on four-point bend test specimens. Based on the results, the presence of thermal butt fusion beads was confirmed to reduce the fatigue lifetime in the low- and medium-cycle fatigue regions while having a negligible effect in the high-cycle fatigue regions.

Bromidrosis is a disease which is also called huchou[호격] in the oriental medicine. This disease produces an odor and a small amount of sweat from the axillary area. Prognosis of the disease could possibly get better with age. This can be explained by the fact that its symptoms begin usually when a person reaches puberty and as the person gets old, the symptoms reduce or disappear even when specific treatments are not applied. Although the disease is not lethal, many patients have difficulties in leading a normal and comfortable life, physically and psychologically with this in mind and some osbservations gained from the literature studies on the causes,symptoms, and treatments, I embarked on a study aimed at finding out the therapies. My study on the literature has produced the following results ; 1. In the oriental medicine, hu-chou[호격] means the characteric smell or odor produced from the fox. 2. The literature studies point out two causes in the oriental medicine. One is natural. The other is acquired. Acquired cases have the following causes: shi-re-nei-yun[濕熱內蘊]. xie-뱌-bu-huo[血氣不和], gan-qi-yu-jie[肝氣鬱結]. 3 There are two therapies in the oriental medicine. One is internal and the other external. out of the two, external therapies were mainly used according to the literature studies that I have consulted. 4. According to my study, the most frequently used herbal medicine was Alunitum(明 礬)(45 times), followed by Minium(密陀僧)(39 times) and Moschus(?香)(21 times respectively). 5. My study also found that bian-zheng[辨證] was not .rarely listed on old literatures. Therefore, old literatures did not clearly show how to root out the disease. They only taught now to alleviate the symptoms and remove the characteric odor.

Allergic rhinitis is an allergic reaction characterized by sneezing, coughing, itchy nose, mouth and throat, congestion and/or nasal discharge. The offending allergens are usually pollens, molds, dust mites and animal allergens. We aimed to observe inhibitory effects of Bojungikgi-tang on incerase of the number of eosinophil and neutrophil, and protective effects of nasal mucosal tissue in the allergic rhinitis. 1. In Inhibitory Effect of Bojungikgi-tang on Increase of the number of Eosinophil in Serum, Bojungikgi-tang showed significant effects.(p〈0.05) 2. In Inhibitory Effect of Bojungikgi-tang on Increase of the number of Neutrophil in Serum, Bojungikgi-tang showed significant effects.(p〈0.05) 3. In histopathologic change of nasal mucosal tissue, Bojungikgi-tang showed significant protective effects. Depending upon above results, it is considered that Bojungikgi-tang has the inhibitory effects on the process of allergic rhinitis and that it could be used in reliving patients of the symptoms caused by allergic rhinitis.

본 논문에서는 마이크로스트립 개방선로와 선형공진기에 대해서 라인의 측방향 전역함수를 이용하여 모멘트법으로 해석하였다. 마이크로스트립 라인의 기판의 유전율 두께와 라인을 폭을 포함하는 측방향의 상관함수를 유도하였다. 제안된 방법을 검증하기 위하여 몇가지의 수치해석 예제에 대하여 제안 방법과 다른 방법에 대하여 해석하여 그 결과를 비교하였다 이 방식이 기존의 방법에 대해서 보다 더 정확한 결과를 얻을 수 있음이 관측되었다. Microstrip open-end and linear resonator are analyzed by method of moment (MoM) taking the entire-domain current distribution, found in literature, along the transverse direction of microstrip line. A transverse correlation function which incorporates permittivity, thickness and width of the line is derived. Numerical examples are investigated and compared with the available other data and methods in order to give the validity of the proposed method. It is found that the proposed method can generate more accurate results than the conventional methods.

Bioremediation is one of the most effective ways to remediate TPH-contaminated sites. However, under actual field conditions that are not at the optimum temperature, degradation of microorganisms is generally reduced, which is why the efficiency of biodegradation is known to be significantly affected by the soil temperature. Therefore, in this study, the labscale experiment was conducted using indigenous crude oil degrading microorganisms isolated from crude oil contaminated site to evaluate the remediation efficiency. Crude oil degrading microorganisms were isolated from crude oil contaminated soil and temperature, which is a significant factor affecting the remediation efficiency of land farming, was adjusted to evaluate the microbial crude oil degrading ability, degradation time, and remediation efficiency. In order to assess the field applicability, the remediation efficiency was evaluated using crude oil contaminated soil (average TPH concentration of 10,000 mg/kg or more) from the OO premises. Followed by the application of microorganisms at 30℃, the bioremediation process reduced its initial TPH concentration of 10,812 mg/kg down to 1,890 mg/kg in 56 days, which was about an 83% remediation efficiency. By analyzing the correlation among the total number of cells, the number of effective cells, and TPH concentration, it was found that the number of effective microorganisms drastically increased during the period from 10 to 20 days while there was a sharp decrease in TPH concentration. Therefore, we confirmed the applicability of land farming with isolated microorganisms consortium to crude oil contaminated site, which is also expected to be applicable to bioremediation of other recalcitrant materials.

VTS관제사의 최소안전거리에 관한 기초 연구

김종성,Kim, Jong-Sung 해양환경안전학회 2013 해양환경안전학회지 Vol.19 No.5

본 연구에서는 우리나라 각 항만 VTS에서 근무하고 있는 현직 관제사들을 대상으로 관제 구역 내에서 선박의 안전한 운항을 위해 선박과 선박 사이 및 선박과 육지(장애물)와의 최소 안전거리를 조사하여 VTS 관제의 효율성을 제고하는데 그 목적이 있다. 이러한 안전한 선박 통항을 위한 기초 자료를 제시하기 위해 우리나라 각 항만 VTS 관제사들이 관제하는 안전이격거리를 각 VTS 센터별, 개인별로 설문 조사 및 분석을 하고 실습선을 이용하여 선박 통항이 밀집되어 있는 싱가포르와 말라카 해협에서의 관제 거리를 서로 비교하여 VTS 관제사간의 최소안전거리에 어떠한 차이점이 있는지를 조사하였다. 설문조사 결과 같은 VTS 소속임에도 불구하고 개인별로 관제하는 최소안전거리에는 많은 차이가 있고 전체적으로 해안선이 완만한 동해항의 경우 관제 안전거리가 타 항만보다 컸으며 해안선이 복잡하고 어선 및 여객선의 입출항이 잦은 목포항이 관제 안전거리가 가장 짧음을 확인할 수 있었다. 또한 동일한 VTS에 근무하는 관제사들이 정형화된 관제 방법에 따라 관제를 할 수 있도록 항만의 자연조건이나 교통량에 적합한 모듈(Module)을 개발할 필요성이 필요하며 향후에는 표준관제절차 수립을 위한 전문가 집단의 충분한 논의가 있어야 할 것으로 사료된다. This study aims to enhance the effectivity of VTS(Vessel Traffic Service) control by investigating the minimum safe distance between vessel and vessel, vessel and land(obstacle) for the vessel's safe navigation within the VTS control area. In addition, to suggest basic data for the safe navigation, this study has done survey and analysis to each VTS center, and individual on the minimum safe distance to VTS operators of each ports of korea. Through ocean voyage by training ship, Singapore and Malacca strait's congested vessel traffic zone's control distance was compared and investigated the difference on safe distance by the different VTS operators. As a result, there was huge difference of minimum safe distance between the VTS operators belong to the same center. Over all, the port with gentle coastline, like donghae, the safe distance was wider than the other port. On the other hand, port with complex coastline and frequent entry and departure of the vessel, like mokpo, the safe distance was the shortest of all. Therefore, development of module suitable to port's natural conditions and traffic volume's necessity is required, for the operators affiliated to the same VTS center control according to formal method. Lastly, the full discussion by the expert group about establishment of standard control procedure in the future should be considered as well.
