최근 전 세계적 기상이변으로 홍수 가뭄 폭설 혹서 혹한 등의 재해 때문에 많은 사람들이 고통에 시달리고 있다. 기상이변으로 인한 재해는 과거에도 존재하였으며 한민족의 역사와 함께하였다. 온고이지신가 이위사의(溫故而知新可以爲師矣)는 논어의 위정편(爲政編)에 나오는 공자의 말씀이다. '옛 것을 익혀 새것을 알면 남의 스승이 될 수 있다'라는 뜻으로 재난을 연구하는 연구자의 입장에서 보면 반드시 새겨둘 구절이다. 역사 속에서 자연재해는 군주(君主)의 부덕(不德)이나 실정(失政)의 소치(所致)로 여겨지고 나아가서는 왕조나 국운의 쇠퇴와도 관련이 이어지기까지 했다. 이미 과거 자연기록에 있었던 일들이며 이러한 사실은 세계문화유산으로 지정된 "조선왕조실록"을 통해 조선시대의 자연재해 기록을 살펴볼 수 있다. "조선왕조실록"을 보면 경술년 현종 11년(1670년 5월 2일) "가없는 우리백성들이 무슨 죄가 있단 말인가. 아, 허물은 나에게 있는데, 어째서 재앙은 백성에게 내린단 말인가." 1671년 말 경신대기근으로 인한 사망자 수가 100만 명에 이른다고 기록도 있다. 기양의례'란 가뭄, 홍수, 전염병 같은 자연재해만이 아니라 개인의 질병과 불행 등 일상적인 삶의 조건을 위협하는 상황이 닥쳤을 때 이를 소멸하고자 거행하는 대표적인 재난문화의 종류이며 비정기적 의례를 의미한다. 조선시대에 기양의례는 재난대응의 상징적인 의미를 갖고 있다. 현재의 우리나라로 보면 재난안전대책 본부와 비견할 수 있다. 조선시대에는 "기양의례"를 통해 임금을 포함한 조정이 적극적 해결의지를 천명하고 각 고을의 관리와 지방군을 동원하여 수습 복구에 최선을 다했다. 부세를 견감하고 구제곡을 지급하는 등의 진휼정책이 뒤따랐다. 백성들도 오가작통제와 향약을 통해 환난상휼을 실천하였다. 이처럼 조선시대에는 비록 기술적인 부분은 미약했지만 재난대응의 체계만큼은 상당히 앞서있었다. 본 연구에서는 조선시대의 강원도 영동지방 자연재난사례를 조선왕조실록을 통해 조사하고 재난에 대응하기 위한 재난문화를 조사하고자 한다.

This study examined the effects of procedural justice on two facets of OCB (OCBI and OCBO) in local public enterprises and the mediating role of intrinsic motivation in these relationships. We verified the hypothesis established by a structural equation model based on PLS. The research data were collected through a survey of 269 employees working for local public enterprises. Research has shown that procedural fairness has a positive effect on intrinsic motivation, organizational citizenship behavior directed at individuals (OCBI), and organizational citizenship behavior directed at the organization (OCBO), while intrinsic motivation has a positive effect on OCBI and OCBO. In addition, intrinsic motivation has been found to have a partial mediating effect in the procedural justice-OCBI relationship and the procedural justice-OCBO relationship respectively. Finally, we present theoretical and practical implications that organizations need to activate intrinsic motivation so that members can induce voluntary organizational civic action through improved procedural fairness.

In recent years, most domestic colleges of engineering are continuously trying to enhance the quality of education in engineering so as to meet the international requirement of education standards of this era. In consequence, the colleges are willing to acquire the accreditation of education by the ABEEK (Accreditation Board for Engineering Education of Korea) so that they can find the right way for the education of engineering and establish concrete educational programs in engineering. In this contribution, we exemplify a case of the College of Engineering in Mokwon University to survey and analyze the current state of education in engineering. We adopt the AS-IS and TO-BE analysis model to assess the system and try to figure out the right way for custom-designed education. The analysis helps understanding of the current situation of local private universities and consequently be used as important data for acquiring the engineering accreditation for global standard.

Hepatic endoplasmic reticulum (ER) stress contributes to the development of steatosis and insulin resistance. The components of unfolded protein response (UPR) regulate lipid metabolism. Recent studies have reported an association between ER stress and aberrant cellular lipid control; moreover, research has confirmed the involvement of sterol regulatory element-binding proteins (SREBPs)-the central regulators of lipid metabolism-in the process. However, the exact role of SREBPs in controlling lipid metabolism during ER stress and its contribution to fatty liver disease remain unknown. Here, we show that SREBP-1c deficiency protects against ER stress-induced hepatic steatosis in mice by regulating UPR, inflammation, and fatty acid oxidation. SREBP-1c directly regulated inositol-requiring kinase 1α (IRE1α) expression and mediated ER stress-induced tumor necrosis factor-α activation, leading to a reduction in expression of peroxisome proliferator-activated receptor γ coactivator 1-α and subsequent impairment of fatty acid oxidation. However, the genetic ablation of SREBP-1c prevented these events, alleviating hepatic inflammation and steatosis. Although the mechanism by which SREBP-1c deficiency prevents ER stress-induced inflammatory signaling remains to be elucidated, alteration of the IRE1α signal in SREBP-1c-depleted Kupffer cells might be involved in the signaling. Overall, the results suggest that SREBP-1c plays a crucial role in the regulation of UPR and inflammation in ER stress-induced hepatic steatosis.

Mobilization of storage lipids is critical for the germination of oil seeds, as they supply carbon and energy until photosynthesis commences in cotyledons. In this study, we determined the levels of plant carnitine and associated changes in these levels from seed germination to cotyledon senescence. We also examined changes in the content of unsaturated fatty acids throughout seedling development. Carnitine levels peaked on day 3 at 14.5 nM in cotyledons and decreased sharply to 7.2 nM on day 4. On development day 3 carnitine levels were maintained at around 3 nM until day 7. The unsaturated fatty acid content dropped by half at the same time as carnitine peaked (day-3), and storage lipids were almost depleted by day 5. Thereafter, carnitine was hardly detected until the second stage of cotyledon senescence, at which stage the carnitine content was 6.8 nM, similar to that on day 4 at the time of fatty acid depletion in the cotyledons. Unsaturated fatty acids levels remained constant in green cotyledons but slightly increased in the senescing cotyledons. The latter can be explained by intracellular breakdown of membrane lipids. This is the first such discovery in developing cotyledons and may offer clues regarding other roles of the acetyl unit transport system in plants. The expression of BOU was closely associated with carnitine metabolism during seed germination and cotyledon development. The results provide support for the possibility of carbon re-routing during the glyoxylate cycle in the supply of energy for early germination and development.

Three frequently used documents by researchers on the Japanese colonial period-Classified Police Records of the Japanese Government-General of korea on the Anti-Japanese Movement 舊 朝鮮總督府 警務局 抗日獨立運 動關係 秘密記錄, Trial Records of Gyeongseong District Court 京城地方法院 裁判記錄 and Filed Documents of Gyeongseong District Court 京城地方法院 編綴文書(while the latter two were collected by the National Institute of Korean History, the former was collected by Asiatic Research Institute of Korea University)-are among the same records group that the Prosecutor's Office of Gyeongseong District Court produced through registration and compilation. As contents related to ideology suppression and thought control were numerous, it could be assumed that most of the materials were produced by the 'Department of Ideology' of the Prosecutor's Office. By examining the administrative records of the 1920's within this group, the process of how the 'Department of Ideology' was formed is clearly shown. As ideological movements for Korea's independence and revolution grew, execution of regulations was further expanded by the Prosecutor's Office. Since the mid-1920's, information on ideology had been separated from general information, was routinely collected heavily, and was considered more valuable than the general information. By the end of the 1920's, the term Ideology Prosecutor 思想係 檢事(meaning a prosecutor who specializes in ideology verification) and the named 'Department of Ideology'(思想部) emerged on the records.

Non-alcoholic fatty liver disease is an independent risk factor for the development of cardiovascular disease, diabetes, hypertension, and kidney disease, and the clinical importance of non-alcoholic fatty liver disease has recently been increasing. In this study, we aim to extract feature values by applying GLCM, a texture analysis method, to ultrasound images of patients with non-alcoholic fatty liver disease. By applying an artificial neural network model using extracted feature values, we would like to classify the degree of fat deposition in non-alcoholic fatty liver into normal liver, mild fatty liver, moderate fatty liver, and severe fatty liver. As a result of applying the GLCM algorithm, the parameters Autocorrelation, Sum of squares, Sum average, and sum variance showed a tendency for the average value of the feature values to increase as it progressed from mild fatty liver to moderate fatty liver to severe fatty liver. The four parameters of Autocorrelation, Sum of squares, Sum average, and sum variance extracted by applying the GLCM algorithm to ultrasound images of non-alcoholic fatty liver disease were applied as inputs to the artificial neural network model. The classification accuracy was evaluated by applying the GLCM algorithm to the ultrasound images of non-alcoholic fatty liver disease and applying the extracted images to an artificial neural network, showing a high accuracy of 92.5%. Through these results, we would like to present the results of this study as basic data when conducting a texture analysis GLCM study on ultrasound images of patients with non-alcoholic fatty liver disease.

It is necessary to analyze the budget power during the budget process of the local council, paying attention to strengthening the capacity of local council and reinforcing expertise to secure accountability. The budget power of council is expressed in various terms such as power of the purse and the authority to control the budget, and focuses on the role of control and check in the council's budget process. The purpose of this study is to analyze the factors that political·administrative variables, social·economical variables affect the budget power of local council. The budget power of councils was set as the budget net modification rate and the period for processing the budget bill at the plenary session. And the effects of various variables were checked. As a result, the local council confirmed that there was a lack of checks and controls in the budget process.

This study attempted to find out the degree of agreement between ultrasound image findings along with analysis of attenuation index and scatter distribution index values within tissues through quantitative measurement analysis using liver ultrasound images. From August 2022 to October 2022, liver ultrasound was performed on 45 patients who were suspected of having fatty liver and who received a prescription for liver ultrasound. As a result of the study, as a result of analyzing the agreement between the ultrasound image findings and the tissue attenuation index, the Kappa value was 0.82 (p<0.05), showing a very high agreement between the two examination methods. In addition, as a result of the agreement analysis between the ultrasound image findings and the scatter distribution index in the tissue, the Kappa value was 0.642 (p<0.05), showing high agreement between the two examination methods. At the time of fat liver prediction, the use of liver ultrasound findings and quantitative ultrasonography techniques, such as intra-tissue attenuation index and intra-tissue scatter distribution index, may be helpful in determining the degree of progression of fatty liver patients.
