"안녕들 하십니까?" 대자보가 2013년 12월 10일에 등장하였다. 이에 동조하는 대자보들이 곳곳에 등장하였으며, 인터넷과 SNS에서 사람들의 입에 뜨겁게 회자하기 시작하였다. 이와 같은 사회현상은 각 언론사의 관점에 따라 의미가 다른 기사의 형태로 독자들에게 전달된다. 또한, 신문의 네칸만화와 만평에서도 특정 사건의 의미전달을 위한 소재로써 적극적으로 활용되어 독자들에게 전달된다. 이는 신문 매체에서 풍자와 비평으로 세상을 관조하는 만화가 독자에게 카타르시스와 함께 사건의 핵심을 쉽고 직관적으로 이해시키는 힘을 갖고 있기 때문이다. "안녕들 하십니까?"의 사회현상은 지나가 버린 과거처럼 언론이나 대중의 관심에서 잊히고 있다. 반면 안녕하지 못한 현상들에 대한 해결은 요원해 보인다. 하지만 만평은 연계관계가 있는 사회현상이 발생할 때 이를 이야기 장치로 활용하여 다시 되새긴다. 독자는 기억 속에서 멀어져간 사회현상을 되새기고 이를 기억하며 사회현상을 다시금 환기한다. 이처럼 만평은 사회적으로 중요한 언론의 역할을 하며, 만화의 장점을 활용한다. 본 연구는 만화가 중요한 사회적 역할과 소임을 가진 중요한 매체임을 주장하는 데 목적이 있다. 신문사의 네칸만화와 만평은 신문사 또는 작가의 관점에 따른 차이는 있을지언정 자기 목소리를 내면서 사회적 역할을 분명히 한다. 만화의 장르 중에서 신문 만화의 사회적 역할은 크게 두 가지로 볼 수 있다. 첫 번째, 사회현상에 적극적으로 개입한다. 즉 과장과 강조, 구체적 지시로 사회현상에 대한 입장과 주장을 분명히 드러낸다. 두 번째, 독자를 설득 또는 이해시킨다. 즉 비슷한 관점을 가진 독자에게 분명한 메시지를 전달한다. 본 연구는 만화의 사회적 역할에 대한 연구의 한 부분으로서, 만화의 부정적인 일부분으로 인해 사회적으로 매도되는 악순환에서 벗어나기를 바라마지 않는다.

긴 이야기구조의 기승전결인 네 국면의 플롯은 패턴화 되어 도식화된 경향이 있다. 인물의 행동에는 인류의 시작과 궤를 같이 하게 되는데 장편연재만화 플롯은 기본적으로 4국면이지만, 단순 배열이 아닌 인류의 추진력이나 행동과 느낌의 패턴을 정리하여 개발한 복잡 배열이다. 이 연구는 만화전문대학생 설문과 답변으로 결과지를 얻은 후, 통합적으로 추출된 장편연재만화작품의 설문 자료를 통하여 장편연재만화 아리스토텔레스 이론인 플롯의 국면, 네 단계와 캐롤 피어슨의 인물원형이론을 통한 4개의 인물의 유형화, 조셉 캠벨의 영웅의 여정이론을 네 단계로 유형화한다. 복잡한 장편연재만화의 이야기 구조가 가진 요소 중 하나인, 인물이 겪는 삶의 과정을 제시하여 간략성과 체계적 기술을 통해 유형화하는 이 연구는 결국 만화작가가 장편연재만화의 복잡하고 긴 이야기의 구조에서 은유하는 것은 무엇인가를 밝히고자함이다. 아리스토텔레스의 플롯이론을 근거로 하는 도입, 발전, 전개 결말구조의 의미가 인류의 삶과 운명의 메타포이며, 융 이론에 영향 받은 융 연구가 캐롤 피어슨의 인물 원형론의 성장단계가 인류의 삶과 운명의 메타포임을, 역시 융 이론에 영향 받은 인류학자 조셉 캠벨 이론들은 희노애락의 복합감정을 영웅원형에 투사하여 영웅의 여정이란 은유를 통해 인류의 삶과 운명의 메타포임을 밝히고 있다. 최종적으로, 제기된 이론들은 크리스토퍼 보글러의 저서에 작가의 '시나리오작성법'으로 접근하여 소개되고 있다. 한편으로 이 메타포는 이 연구목표이자 목적이기도 하다. 연구에서 추출된 장편연재만화는 긴 이야기가 복잡하고 얽힌 듯이 보여도 인물이 집을 떠나 모험과 난관을 겪고 세계와의 또 다른 만남을 통해 거부와 갈등, 그리고 경쟁과 전쟁, 시련을 겪으며 보상을 얻어 귀환하는 여정의 과정 중 정신적, 심리적, 상징적 성장으로 결국, 영웅으로 획득되며 만화라는 이미지를 통하여 우리의 내면 성찰에 대한 의미 부여를 플롯에 의해 서사적으로 표현하고 있다. 복잡해보이지만 장편연재만화이야기의 기본구조가 플롯 4단계이며 장편연재만화작품에서 범상치 않은 인물이 여행과 모험을 떠나는 과정에서 성장하는 삶의 방식을 크게 나누어 볼 때, 네 단계의 영유아동기, 청년기, 중년기, 말년기의 상징성을 지닌 심리적 성장과정이며, 인물이 유형화된 특성도 크게 네 단계의 부류로 나누어 성장과정을 설명할 수 있게 한다. 성장할 인물의 표상화인 영웅의 여정, 역시 크게 네 단계의 여정으로 압축되어 설명된다. 즉 이론을 통하여 만화의 4국면의 플롯의 복잡 배열은 삶의 순서를 통한 성장구조의 진행과의 흐름이 일치한다는 것을 발견하였다. 동시에 인물이 영웅으로 거듭나는 성찰의 메타포이며 장편연재만화작가들의 작품을 통하여 인생국면 4단계인 인물의 성장과 삶을 통찰하는 은유를 발견하였다. 만화작가가 의도하는 장편연재만화작품의 긴 이야기란, 플롯의 논리적구성법에 의해 인물이 여정을 떠나 역경과 어려움을 겪으며 삶이 변화되고 그의 성장과정은 유형화된 이미지로 제시하여 성찰에 도달함을 영웅적으로 표현하는 것이며, 독자는 삶과 인생에서 만화이야기의 이미지의 시공간을 공유하는 동시에 감동을 통하여 정서상 인물과 같은 체험을 하게 되었음을 인식하게 한다.

This study aimed to investigate the relaxation effects and its underlying mechanisms of Rubus coreanus(RC) extract in contracted rabbit corpus cavernous tissues by phenylephrine(PE) $1{\mu}M$. In order to define the relaxation effects of RC, rabbit corpus cavernous tissues were prepared in $2{\times}2{\times}6mm$ sized strip. The dose-dependent relaxation responses of RC at 0.01-3.0 $mg/m{\ell}$ in contracted strips induced by PE were measured and also observed after endothelial denudation. To analyze the underlying mechanisms of RC-induced relaxation, indomethacin(IM), tetraethylammonium chloride(TEA), $N{\omega}$-nitro-L-arginine (L-NNA), methylene blue(MB) were treated before RC extract infused into precontracted strips induced by PE. To study the effect of RC extract on influx of extracellular $Ca^{2+}$ in corpus cavernous strips, calcium chloride(Ca) 1 mM infused into precontracted strips induced by PE after pretreatment of RC extract in $Ca^{2+}$-free krebs-ringer solution. To investigate cytotoxic activity and nitric oxide(NO) concentration of RC extract on human umbilical vein endothelial cell(HUVEC), cell viability on HUVEC was measured by MTT assay, and NO concentration was measured by Griess reagent system. The cavernous strips were significantly relaxed by RC extract at 1.0 $mg/m{\ell}$, 3.0 $mg/m{\ell}$ and the relaxation responses to RC were inhibited significantly by endothelial disruption. The pretreatment of IM, TEA didn't affect RC extract-induced endothelium-dependent relaxation, but the pretreatment of L-NNA, MB reduced RC extract-induced endothelium-dependent relaxation. When $Ca^{2+}$ was supplied the cavernous strips which were precontracted by PE in a $Ca^{2+}$-free krebs-ringer solution, contraction of strips was increased, but pretreatment of RC inhibited contractile response to $Ca^{2+}$. When RC extract was applicated on HUVEC, NO concentration was increased. Our findings show that RC extract exerts a relaxing effect on corpus cavernosum in part by suppressing influx of extracellular $Ca^{2+}$ through activating the NO-cGMP system.

The role of mitogen-activated protein kinase (MAPK) in the decreased contractile response to phorbol ester in aortic smooth muscle strips from deoxycorticosterone acetate (DOCA)-salt hypertensive rats was examined. Norepinephrine (NE) evoked greater contractility in aortic strips from DOCA rats than in those of sham-operated rats. 12-Deoxyphorbol 13-isobutyrate (DPB) induced contraction in $Ca^{2+}-free$ medium, which was diminished in strips from DOCA rats compared to sham-operated rats. Vasoconstrictions induced by these stimulants were inhibited by SB203580 and PD098059, inhibitors of p38 MAPK and extracellular signal-regulated kinase (ERK) 1/2, respectively, in both strips. The phosphorylation of p38 MAPK and ERK1/2 induced by NE was greater in strips from DOCA rats compared to those from sham-operated rats, and this phosphorylation was inhibited by the kinase inhibitors. DPB increased the phosphorylation of p38 MAPK and ERK1/2 in strips from both animals, and the increment of p38 MAPK phosphorylation by the stimulant was diminished in strips from DOCA rats compared to sham-operated rats. These findings suggest that the $Ca^{2+}-independent$ contraction evoked by DPB results from the activation of MAPKs in rat aortic smooth muscle and that the attenuated contractility by DPB in DOCA rat appears to be associated with diminished p38 MAPK activity.

Strengthening with near surface mounted carbon fibre reinforced polymers (NSM-CFRP) is a strengthening technique that have been used for several decades to increase the load carrying capacity of reinforced concrete members. In Iraq, many concrete buildings and bridges were subjected to a wide range of damage as a result of the last war and many other events. Accordingly, there is a progressive increase in the strengthening of concrete structures, bridges in particular, by using CFRP strengthening techniques. Near-surface mounted carbon fibre polymer has been recently proved as a powerful strengthening technique in which the CFRP strips are sufficiently protected against external environmental conditions especially the high-temperature rates in Iraq. However, this technique has not been examined yet under repeated loading conditions such as traffic loads on bridge girders. The main objective of this research was to investigate the effectiveness of NSM-CFRP strips in reinforced concrete beams under repeated loads. Different parameters such as the number of strips, groove size, and two types of bonding materials (epoxy resin and cement-based adhesive) were considered. Fifteen NSM-CFRP strengthened beams were tested under concentrated monotonic and repeated loadings. Three beams were non-strengthened as reference specimens while the remaining were strengthened with NSM-CFRP strips and divided into three groups. Each group comprises two beams tested under monotonic loads and used as control for those tested under repeated loads in the same group. The experimental results are discussed in terms of load-deflection behavior up to failure, ductility factor, cumulative energy absorption, number of cycles to failure, and the mode of failure. The test results proved that strengthening with NSM-CFRP strips increased both the flexural strength and stiffness of the tested beams. An increase in load carrying capacity was obtained in a range of (1.47 to 4.49) times that for the non-strengthened specimens. Also, the increase in total area of CFRPs showed a slight increase in flexural capacity of (1.02) times the value of the control strengthened one tested under repeated loading. Increasing the total area of CFRP strips resulted in a reduction in ductility factor reached to (0.71) while the cumulative energy absorption increased by (1.22) times the values of the strengthened reference specimens tested under repeated loading. Moreover, the replacement of epoxy resin with cement-based adhesive as a bonding material exhibited higher ductility than specimen with epoxy resin tested under monotonic and repeated loading.

A trial was conducted to determine the effect of abrasive strips and abrasive paint in layer cages on claw length and claw sharpness, foot condition, feather cover and mortality of hens. During the preparation of the cages for the experiment it was simpler and took less time to apply the pre-prepared paint with a spatula to the egg guard compared to sticking the abrasive strips onto the egg guard. Fitting the strips took longer because it had to be cut from a 25 mm roll, cut into the appropriate lengths, the tape backing removed and then stuck onto the egg guard section. Abrasive paint was more effective as a claw shortener than abrasive strips. The birds using the abrasive paint had the shortest (p<0.05) claw length and lowest (p<0.05) claw sharpness. One of the original reasons for reducing claw length with claw shorteners was to reduce mortality by minimising skin skin abrasions caused by the claws. Surprisingly hen mortality from prolapse and cannibalism was higher (p<0.05) in cages fitted with abrasives. There are no other reports in the literature showing an increase in prolapse and cannibalism from hens using abrasives.

Though the airborne laser scanning (ALS) technique is becoming more popular in many applications, horizontal accuracy of points scanned by the ALS is not yet satisfactory when compared with the accuracy achieved for vertical positions. One of the major reasons is the drift that occurs in the inertial measurement unit (IMU) during the scanning. This paper presents an algorithm that adjusts for the error that is introduced mainly by the drift of the IMU that renders systematic differences between strips on the same area. For this, we set up an observation equation for strip-wise adjustments and completed it with tie point and control point coordinates derived from the scanned strips and information from aerial photos. To effectively capture the tie points, we developed a set of procedures that constructs a digital surface model (DSM) with breaklines and then performed feature-based matching on strips resulting in a set of reliable tie points. Solving the observation equations by the least squares method produced a set of affine transformation equations with 6 parameters that we used to transform the strips for adjusting the horizontal error. Experimental results after evaluation of the accuracy showed a root mean squared error (RMSE) of the adjusted strip points of 0.27 m, which is significant considering the RMSE before adjustment was 0.77 m.

LiDAR (Light Detection And Ranging) strip adjustment is process to improve geo-referencing of the ALS (Airborne Laser Scanner) strips that leads to seamless LiDAR data. Multiple strips are required to collect data over the large areas, thus the strips are overlapped in order to ensure data continuity. The LSA (LiDAR Strip Adjustment) consists of identifying corresponding features and minimizing discrepancies in the overlapping strips. The corresponding features are utilized as control features to estimate transformation parameters. This paper applied SURF (Speeded Up Robust Feature) to identify corresponding features. To improve determination of the corresponding feature, false matching points were removed by applying three schemes: (1) minimizing distance of the SURF feature vectors, (2) selecting reliable matching feature with high cross-correlation, and (3) reflecting geometric characteristics of the matching pattern. In the strip adjustment procedure, corresponding points having large residuals were removed iteratively that could achieve improvement of accuracy of the LSA eventually. Only a few iterations were required to reach reasonably high accuracy. The experiments with simulated and real data show that the proposed method is practical and effective to airborne LSA. At least 80 % accuracy improvement was achieved in terms of RMSE (Root Mean Square Error) after applying the proposed schemes.

The aim of this study was to evaluate the mechanism of vasodilation of Lespedezea cuneata(LC) in rabbit common carotid artery and cavernosal smooth muscle. LC relaxed arterial strips precontracted with norepinephrine and cavernosal strips precontracted with phenylephrine. The arterial relaxation effects of LC was endothelium-dependent. $N{\omega}$-nitro-L-arginine(L-NNA), NOS inhibitor, methylene blue(MB), cGMP inhibitor, indomethacin(IM), cyclo-oxygenase inhibitor and tetraethylammonium chloride(TEA), KCa-channel blocker attenuate the relaxation responses of LC in arterial strips. In $Ca^{2+}$-free krebs-ringer solution, pretreatment of LC extract significantly reduced the contraction induced by addition $Ca^{2+}$. L-NNA reduced LC extract-induced relaxation in cavernosal strips, but IM, TEA and MB didn't affect LC extract-induced relaxation. When LC extract was applicated on human umbilical vein endothelial cell, the nitric oxide concentration was increased. We conclude that in rabbit common carotid artery, LC may suppress influx of extra-cellular $Ca^{2+}$ through the release of endothelium derived relaxing factor including nitric oxide, prostacyclin, endothelium derived hyperpolarizing factor. And LC exerts a relaxing effect on corpus cavernosum through activating the NO.

The punching shear strength of concrete flat plates is one of the topics of intensive research in recent years by various concrete structures researchers. This paper reviews four current methods of analysing the punching shear strength at the corner-and edge-column positions of reinforced concrete flat plates. They include those recommended in the Australian Standard AS3600-1988, the American Concrete Institute ACI318-89 and the British Standard on Concrete Practices (BS8110) as well as the approach developed at the University of Wollongong, Australia. Based on half-scale model test results, a comparative study of these four analysis methods is made with regard to their limitation, accuracy and reliability. It is found that the Wollongong approach in general gives the best performance in predicting the punching shear strength of flat plates with torsion strips and those with spandrel beams. The Australian Standard procedure performs just as satisfactorily for flat plates with torsion strips but tends to be unsafe for those with spandrel beams. Both the ACI and the British methods are applicable only to flat plates with torsion strips; they also tend to give unsafe predictions for the punching shear strength.
