프로젝션 매핑 기법은 현재 거의 모든 장르의 공연예술에서 다각적으로 활용되고 있으며, 이에 따라 다양한 분야의 예술가들이 이를 활용한 콘텐츠 제작에 참여하고 있는 상황이다. 프로젝션 매핑 콘텐츠의 다양화는 제작자들로 하여금 더욱 참신한 시각 효과에 대한 시도를 하는 계기가 되었고, 이는 곧 기존에는 프로젝션 매핑 콘텐츠 제작에서 사용되지 않았던 카메라 움직임을 활용한 시점의 변화로 이어졌다. 프로젝션 매핑 영상에 있어서 카메라 움직임의 활용은 시각적 촉각성을 극대화시켜 관객이 콘텐츠에 더욱 몰입할 수 있도록 도와주는 것으로 분석된다. 본 논문에서는 이러한 프로젝션 매핑의 새로운 시각적 표현법인 '카메라 움직임'에 대한 이론적 고찰과 이를 적용한 프로젝션 매핑 작품 사례 분석을 진행하였다. 이를 통해 영화적 영상 문법으로만 적용되었던 카메라 움직임을 프로젝션 매핑 환경에 적합하게 재구성하고 최적의 시각 효과를 창출하기 위한 가이드라인을 제시하고자 한다.

무릎의 신전이 방해되는 이유는 여러 가지가 있다. 하지만 우리가 특별히 구조적인 기형을 환자에게서 찾아내지 못하는 한 넙다리근육 강화나 신전을 위한 하지 폄근육군 완화운동 방법을 알려주는 것 이외에 별달리 해줄 수 있는 것이 없다. 이 연구에서 저자는 Sacro-Occipital Technique을 활용한 무릎 움직임 방해 완화에 대하여 새로운 사례연구를 하였다. 이 연구에서는 무릎을 완전히 펴고 서지 못하는 14세의 여학생에게 7회의 S.O.T categoryⅠ. 방법이 적용되었으며 이로서 별다른 방해 없이 무릎을 펴고 설수 있게 되었다. 대체적으로 무릎을 곧바로 펴지 못하는 많은 경우 근육 연조직 마사지 등을 뒤넙다리근에 적용하여 완화 시켜 보기도 한다. 그러나 만약 이러한 방법들이 잘 듣지 않는다면 S.O.T categoryⅠ. 방법을 고려하여 보는 것도 도움이 될 수 있을 것으로 사료된다.

This study measures the subjectivity(opinions, attitudes) of college women. Identifying the schemata (structure of subjectivity) would be a basic step for the sexual educational program and alternative strategies of sexual harassment. More concretely, those following research questions are focused. 1) The subjective schemata : find out typologies based on the opinions and attitudes toward the sexual harassment. 2) Applications : describe the characteristics of each type. 3) Alternatives : provide suggestion of the alternative strategies for solving the sexual harassment problems of women. Q-Methodological method was used for that purpose. As the research method, Q-statements were collected preliminary to the study of through indepth interviews and a literature review. For the study 34 Q-statements were selected. There were 48 college women as subjects for the research. The 48 college women sorted the 34 statements using the principle of Forced Normal Distribution. The principle of Forced Normal Distribution, which has nine scales to measure the individual opinions, was called. Q-Factor Analysis by using PC Quanl Program to supply the material. According to the outcomes of this study, there were four categories of special opinion about the sexual harassment in college women. The first type is called Blaming offenders type. This type is to hold offenders accountable. The second type is called Preventive alternative strategies type. This type is to take preventive measures. The third type is called Blaming social structure type. This type is to hold the society as a whole responsible. The fourth type is called Blaming victims type. This type is to hold victims accountable. As a result, We not need to change our perspective of women's health problems and need to develop realistic way of caring those women in suffering women's problems. Followings are to be suggested of the alternative strategies for solving the sexual harassment problems. Finally, The result of the study will provide us the clue for developing the sexual educational program and alternative strategies for women's sexual harassment problems.

Background: Colorectal cancer is the fourth most common cancer worldwide and the second leading cause of cancer-related death. FOLFOX is the most common regimen used in the first-line chemotherapy in advanced colorectal cancer, but only half of the patients respond to this regimen and we have almost no clue in predicting resistance in such first-line application. Methods: To explore the potential molecular biomarkers predicting the resistance of FOLFOX regimen as the first-line treatment in advanced colorectal cancer, we screened microRNAs in serum samples from drug-responsive and drug-resistant patients by microarrays. Then differential microRNA expression was further validated in an independent population by reverse transcription and quantitative real-time PCR. Results: 62 microRNAs expressing differentially with fold-change >2 were screened out by microarray analysis. Among them, 5 (miR-221, miR-222, miR-122, miR-19a, miR-144) were chosen for further validation in an independent population (N=72). Our results indicated serum miR-19a to be significantly up-regulated in resistance-phase serum (p=0.009). The ROC curve analysis showed that the sensitivity of serum miR-19a to discriminate the resistant patients from the response ones was 66.7%, and the specificity was 63.9% when the AUC was 0.679. We additionally observed serum miR-19a had a complementary value for cancer embryonic antigen (CEA). Stratified analysis further revealed that serum miR-19a predicted both intrinsic and acquired drug resistance. Conclusions: Our findings confirmed aberrant expression of serum miR-19a in FOLFOX chemotherapy resistance patients, suggesting serum miR-19a could be a potential molecular biomarker for predicting and monitoring resistance to first-line FOLFOX chemotherapy regimens in advanced colorectal cancer patients.

Background: Recently symptoms-based screening questionnaires have gained attention for screening for a neuropathic pain component (NePC) in various chronic pain conditions. The present study assessed the usefulness of four commonly used NePC screening questionnaires including the Self-completed douleur neuropathique 4 (S-DN4), the ID Pain, the painDETECT questionnaire (PDQ), and the Self-completed Leeds Assessment of neuropathic Symptoms and Signs (S-LANSS) questionnaire in patients with chronic low back pain (CLBP) to assess the presence of NePC. Methods: This is a single-center cross-sectional study where patients with CLBP, with or without leg pain, were included. Participants were initially screened for NePC presence by a physician according to the regular practice, and later assessed using screening questionnaires. The diagnostic accuracy of these questionnaires was compared assuming the physician-made diagnosis as the gold standard. Results: A total of 215 patients with CLBP of which 164 (76.3%, 95% CI, 70.2-81.5) had a NePC were included. S-DN4, ID Pain, and PDQ have an area under the curve (AUC) > 0.8 indicating excellent discrimination. However, S-LANSS has an AUC of 0.69 (0.62-0.75), indicating low discrimination. S-DN4 has a significantly higher AUC as compared to ID Pain (d(AUC) = 0.063, P < 0.01) and S-LANSS (d(AUC) = 0.197, P < 0.01). But the AUC of S-DN4 does not significantly differ from that of PDQ (d(AUC) = 0.013, P = 0.62). Conclusions: S-DN4, ID Pain, and PDQ, but not S-LANSS, have good discriminant validity to screen for NePCs in patients with CLBP. Despite using all the tests, 20-30% of patients with an NePC were missed. Thus, these questionnaires can only be used as an initial clue in screening for NePCs, but do not replace clinical judgment.

Objectives: According to Korean Medicine theory, the skin color of LU10 serves as a diagnostic clue to dyspeptic symptoms. The aims of this study were (1) to find the difference of skin color in LU10 region between functional dyspepsia (FD) and healthy control (HC) and (2) to examine the relationship between LU10 skin color parameters and dyspeptic symptoms. Methods: 39 participants (29 FD and 10 HC) have participated in this study. They were asked to complete gastrointestinal scale (GIS), gastrointestinal symptom rating scale (GSRS), Nepean dyspepsia index (NDI), functional dyspepsia-related quality of life (FD-QoL), visual analogue scale (VAS) for dyspeptic symptoms, food retention questionnaire (FRQ) and cold heat questionnaire (CHQ). $L^*$ (luminance), $a^*$ (red-green balance) and $b^*$ (yellow-blue balance) values of LU10 region were calculated through digital images of the participant's hand. Then we evaluated test-retest reliability of $L^*$, $a^*$ and $b^*$ values of LU10 region. Additionally, we compared $L^*$, $a^*$ and $b^*$ values of LU10 between FD and HC, and examined the relationship between LU10 color parameters and seven questionnaires scores. Results: Only $L^*$ values in LU10 region were significantly higher in FD compared with HC. GIS scores and the subset scores of NDI had a positive correlation with $L^*$ values significantly. Correlation coefficients of test-retest reliability of skin color measurement of LU10 ranged from 0.871 to 0.936 representing very strongly statistically significant (P<0.001). Conclusions: We confirmed the difference of skin color in LU10 region between FD and HC, and relationship between LU10 skin color parameters and dyspeptic symptoms.

Soil samples were screened for actinomycete strains capable of producing phospholipase D, and a strain, Streptomyces sp. YU100, showing a high transphosphatidylation activity was isolated. This strain secreted phospholipase D in a culture broth after 12 h of cultivation, and its productivity continued to increase for 36 h of fermentation. In addition, its transphosphatidylation rate of phosphatidylcholine to phosphatidylserine was almost $68\%$ within 1 h. The morphological and chemotaxonomical characteristics showed that this strain could be classified as a number of the Streptomycetaceae family, particularly due to the spiral form of its spore chain consisting of 60-70 smooth spores $(0.75{\times}1.0{\mu}m$) on an aerial mycelium, FA-2c type of fatty acid profile in the cell wall, and LL-DAP component in the cell wall peptidoglycan. A phylogenetic analysis of the 16S rDNA provided a clue that the strain YU100 was actually a member of the genus Streptomyces, because the determined sequence exhibited a higher homology with Streptomyes sp. ASB27, S. peucetius JCM9920, and S. griseus ATCC10137. A dendrogram based on the 16S rDNA sequences also showed a phylogenetic relationship between the strain YU100 and these strains. However, the strain YU100 has not yet been assigned to a particular species, because of absence of any other classified species with a high matching score.

Solar wind density depletions are phenomena that solar wind density is rapidly decreased and keep the state. They are generally believed to be caused by the interplanetary (IP) shocks. However, there are other cases that are hardly associated with IP shocks. We set up a hypothesis for this phenomenon and analyze this study. We have collected the solar wind parameters such as density, speed and interplanetary magnetic field (IMF) data related to the solar wind density depletion events during the period from 1996 to 2013 that are obtained with the advanced composition explorer (ACE) and the Wind satellite. We also calculate two pressures (magnetic, dynamic) and analyze the relation with density depletion. As a result, we found total 53 events and the most these phenomena's sources caused by IP shock are interplanetary coronal mass ejection (ICME). We also found that solar wind density depletions are scarcely related with IP shock's parameters. The solar wind density is correlated with solar wind dynamic pressure within density depletion. However, the solar wind density has an little anti-correlation with IMF strength during all events of solar wind density depletion, regardless of the presence of IP shocks. Additionally, In 47 events of IP shocks, we find 6 events that show a feature of blast wave. The quantities of IP shocks are weaker than blast wave from the Sun, they are declined in a short time after increasing rapidly. We thus argue that IMF strength or dynamic pressure are an important factor in understanding the nature of solar wind density depletion. Since IMF strength and solar wind speed varies with solar cycle, we will also investigate the characteristics of solar wind density depletion events in different phases of solar cycle as an additional clue to their physical nature.

Capitalism is based on a material desire of the human being. the social control of capital value and the management of capital ability reflects the actual condition of the capitalism well. The unconstrained growing and the expansion of capitalism, it finally lost social meaning and an importance of human being element and the safety of the civilian life, began to threat the security of citizen by forming over the material center structure of society. Improving human life quality and material richness on their life leads positive factor of capitalism whereas is causing several crimes through the society which is being threatened around a human being life for a negative factor of the capitalism. Therefore capitalistic social system has offered both a positive factor 'growing' and 'richness' and that of a negative 'structural poverty' and 'lack of security' and they have been remaining the assignment of capitalism 'poverty' and 'security' by settlement in the society for a extremely phenomenon of both sides. The objective of this research is to build its study theory and establish its causal relation by illuminating for the social environment of capitalism for a private guard or a development background of the civil security contributing for citizen security, as well as gets the clue of the development possibility of the civil guard and escort field and the development of capitalism. In Korea because their recognition of the study approach and the social safety for social security control function is still staying first step and our daily life is annoying from various threat of the society, many studies and the realistic necessity of experience related with social security is being studied. In addition, The development possibility of the civil guard and defense at the civil field which will be keep the social security has a wide position but its study approach and realistic comprehension is still in insufficient condition. Consequently, this research is started to grasp the security of civil fiend and to grope a development possibility through the research of capitalism.

In the study of iron artifacts, microstructure investigation is an indispensable step to find out the manufacturing method and skill. The iron weapons that we have excavated and investigated at the ruins of Gohyun Castle site, Hadong-gun, Kyungnam Province are traced to the era of Choson Dynasty. By sampling specimens of some artifacts, we have made microstructure investigation and component analysis of them. For microstructure investigation we used metallographic microscopes, and for component analysis we used the methods of C/S analysis and Inductively coupled plasma emission spectrometry (ICP) analysis which is designed to verify components and contenets of a very small amount elememt. Microstructure of the artifacts is mainly divided into three parts. Inner part is Widmanstatten, a typical overheated structure, upon which we can see another part with fine grains and with extremely small quantities of carbon. And on the surface, there is a carbonized part. When the shape is formed through forging process at a high temperature the carbon content of the surface is getting down and the grains come to be finer. Next, carbonizing process is to be done for hardening the surface, which is followed by cooling process. Cooling rates seem to be different from artifacts to artifacts. All artifacts have clearly distinguishable grain boundaries in their unique structure. Since this kind of structure is rarely found, it seems to offer a clue to find out the manufacturing method. The outcome of component analysis is almost the same with that of microstructure investigation. As is demonstrated by C/S analysis, carbon content is 0.39-1.24% and sulfur is contained 0.0005-0.010%.
