연구배경: 아세틸 콜린 유발 검사시 발생하는 흉통과 허혈성 심전도 변화가 아세틸 콜린에 의해 발생하는 관상동맥의 내피세포 기능에 어떤 영향을 주는지 알아보고자 했다. 방법: 흉통으로 내원하여 관상동맥 조영술과 아세틸 콜린 유발검사를 시행받은 1,085명의 환자를 대상으로 하였다. 아세틸 콜린 유발 검사를 하는 동안 허혈성 심전도 변화 및 흉통의 발생 유무에 따른 관상동맥 내피세포 기능의 특징을 비교하였다. 결과: 539명의 환자에서 아세틸 콜린 검사시 내피세포 기능 장애가 발생 하였다. 허혈성 심전도 변화가 있었던 그룹이 심전도 변화가 없었던 그룹보다 흉통이 더 많았고(78.1% vs. 60.8%, P=0.007), 관상동맥 조영술상 다발성 관상동맥 경련이 빈번하였고(59.4% vs. 40.6%, P=0.004), 관상동맥의 경련 정도도 더 심하였다(64.1% vs. 46.5%, P=0.006). 흉통이 있었던 그룹이 흉통이 없었던 그룹보다 허혈성 심전도 변화의 빈도가 더 높았다(14.7% vs. 7.5%, P=0.007). 또한 흉통이 있었던 그룹이 관상동맥 경련이 다발성으로 발생하는 경우가 많았고 (50.7% vs. 29.5%, P<0.001), 미만성으로 발생하는 경우가 많았고(87.1% vs. 75%, P<0.001), 관상동맥의 경련의 정도도 더 심하였다(51.6% vs. 43.5%, P=0.041). 결론: 아세틸 콜린 유발검사시 발생하는 허혈성 심전도 변화와 흉통은 관상동맥 경련의 정도와 경련이 발생하는 관상동맥 개수와 연관이 있다. Background: ECG changes and chest pain during acetylcholine (Ach) provocation tests may constitute important clinical parameters for Ach-induced endothelial dysfunction. We investigated the association between ischemic ECG changes and chest pain during the Ach-provocation test and angiographic characteristics of Ach-induced endothelial dysfunction. Methods: A total of 1,085 patients with anginal symptoms underwent diagnostic coronary angiography (CAG) and Ach-provocation tests. We compared angiographic characteristics of Ach-induced endothelial dysfunction according to the presence of ECG change and chest pain. Results: A total of 539 patients experienced Ach-induced endothelial dysfunction. Patients who experienced ECG change group suffered more frequent chest pain (78.1% vs. 60.8%, P=0.007), angiographically more frequent multiple coronary artery spasm (59.4% vs. 40.6%, P=0.004), and more severe coronary artery spasm (64.1% vs. 46.5%, P=0.006) than patients without ECG change. However, there was no difference in the length of endothelial dysfunction between the groups. The incidence of ischemic ECG changes in patients with chest pain was higher than in patients without chest pain (14.7% vs. 7.5%, P=0.007). Patients who experienced chest pain more often experienced multiple (50.7% vs. 29.5%, P<0.001), diffuse (87.1% vs. 75%, P<0.001), and severe coronary artery spasm (51.6% vs. 43.5%, P=0.041) than patients without chest pain. Conclusion: Ischemic ECG changes and chest pain during the Ach-provocation test are associated with multi-vessel involvement and severe coronary artery spasm. Chest pain is associated with the length of endothelial dysfunction, but ischemic ECG change is not.

This study is a late study of “An Exploratory Study on STI policy impact assessment”. In the research of 2015, in principle, it is necessary to evaluate not only R&D investment but also general policies such as various promotion systems, standards and regulations by putting the term “policy impact assessment” in front of it We emphasized the points. However, it is practically very difficultto collect and analyze detailed data of all STI policies. In addition, it is also restricted to allow policy researchers to access data within a certain range. Therefore, this study focuses on the impact assessment of R&D investment, which accounts for the largest percentage of STI policies. In this research, the impact assessment system of R&D investment is analyzed by classifying it into evaluation of economic impact and social impact assessment. Also, the evaluation of economic impact was analyzed separating into a micro viewpoint and a macro viewpoint. First, The analysis of the economic impact assessment of the micro viewpoint relates to how the government’s R&D investment affects enterprises. Specifically, the main analysis target was the employment and investment of companies, the impact on sales and profits. Second, The Analysis for macroeconomic impact assessment on the economy is related to the influence of government’s R&D investment such as national economic growth, employment etc. We also analyzed the spillover effect by industry according to R&D investment. Third, The social impact assessment is to analyze how R&D investment has impacted technology-based social change. This study is a very difficult attempt. However, we analyzed from the point of view of the consumer considering all social change areas as much as possible. The results of the study are summarized as follows. First, the study of economic impact evaluation shows the effect of R&D investment and it can be used as a basis to improve the efficiency and goal of R&D investment in future sectors such as employment, economic growth and investment. Second, through research on social impact assessment, government R&D investment has focused on specific areas in terms of improving the quality of life and social development of people, and confirmed that most social sectors are neglected. In addition, we proposed policy priorities for specific social change indicators and social sectors and proposed long-term R&D investment strategies. Finally, this study is expected to contribute to the establishment of future strategy of private enterprise through the measurement of social change index, the social influence of private research and development, and the influence of technology shock from abroad.

서한(西漢)의 서역변강정책(西域邊疆政策)

장석재 ( Chang Seog Jae ) 중국사학회 2018 中國史硏究 Vol.115 No.-

Prior to the Han’s advance, people in many countries in the Western Regions lived a settled existence in most cases and they had castles, fields, and livestock. They were different from the Xiongnu Wusun, but all of them were subjected to the Xiongnu. Therefore, the Han’s advance into the Western Regions meant a war against the Xiongnu, which was dominating the northwestern border area of the Han. In the early days after foundation, the Han was not stable politically, economically, or militarily. The Han maintained humiliating friendly relationships with the Xiongno, which was dominating the northwestern border area, while offering gold, cotton and, colored silk every year. China entered a new stage during the reign of Wudi, who ascended the throne after ‘the rule of Wenjing.’ Wudi firmed up the centralized power system to construct the power base stably internally and established a foundation of a multi-ethnic feudal state centering on Han Chinese, through the expansion of territories mobilizing the armed forces externally. The Han’s exchange with the Western Regions occupies an important position in the history of east and west traffic and the history of the Western Regions. The basic framework of Chinese northwestern border area policies was also established at this time, and this framework still has important implications in relation to border area issues. In order to understand the basic framework of Chinese border area policies, the view of Heaven’s will(天命觀) since the Western Zhou Dynasty period should be examined. The view of Heaven’s will refers to the proxy rule of the world by a son of Heaven, who is a representative of Heaven. Therefore, the world in the Western Zhou Dynasty period meant the range ruled by a son of Heaven based on Heaven’s will. According to this order, only the world acknowledging the order of the son of Heaven was ‘China(華).’ Xiongnu existed in the marginal area of China. The unified Empire Han made Confucianism into its ideology of ruling. As Confucianism was adopted as national studies during the reign of Wudi, Confucianism was reflected on political ideas in the form of idealized China and barbarian thought and Feudalism. Accordingly, the Emperor emerged as the only ruler in the world who receives Heaven’s will and deputizes Heaven’s intentions, and the ruling territory of the Han was expanded into the world including Yixia(夷夏). Accordingly, political organizations were constructed into the inside the boundary(內藩) and outside the boundary(外藩) under the emperor at the summit and the ruling territory was defined. The inside the boundary area is composed of the county regions directly ruled by the emperor, the kingdoms of feudal lords, and the states of feudal lords. This area was where all of the emperor’s virtue, manners, and laws are effective. The outside the boundary area refers to the regions directly ruled by the chiefs of barbarians, who are politically and militarily independent and the emperor’s ruling power did not directly reach these regions. In these regions, only the civilizing influences of the emperor such as manners and virtues were effective. This study explored the Earlier Han’s strategies to manage the Western Regions and the strategies’ effects on later generations. Thereafter, because this study was conducted from the viewpoint of the history of border area ruling, in this paper, first, the processes of opposition, struggles, and wars between the Han and the Xiongno undergone over the Western Regions were described and second, with what political means and strategies the Han subjugated various countries in the Western Regions and how the Han ruled the countries were examined for the 80 years from the beginning of the Han’s advance into the Western Region to the establishment of the Protectorate of the Western Regions and for the period after the establishment of the Protectorate of the Western Regions to the period of Wangmang(王莽). The Han’s management of the Western Regions is a process of acquiring and controlling colonies by a powerful nation from the people of a small and weak power. China gave the feudalist idea in the idealized form termed China centric world order to the process to interpret the process as a process of the expansion of the territory and the establishment of a multi-national state and mentions this as a tradition and feature of Chinese diplomacy. Considering whether this idea could be realized even when China is weak, analyzing the border area policies of China in early days is thought to be meaningful work. For the ancient Chinese state of which Chang'an was the capital, the stabilization of the northwestern border area was an important issue directly connected to the security of the dynasty. Although the Xiongnu power had been a serious threat to the Han since the early days of the foundation of the country, the Han, which was relatively weak, had no choice but to use friendly relation strategies. The Han, that had been building up its power behind the friendly relation strategies, began to exert its power during the reign of Wudi. Wudi raised the army for the subjugation of the Xiongnu while dispatching Zhang jian to Dayue clan and Wusun clan two times. This opened the road between the Han and the Western Regions. This road, which has an important meaning in the history of east-west traffic and the history of the Western Regions, became the road for the Han’s ruling of most countries in the Western Regions instead of the Xiongnu 80 years later. The modern meaning of the Han’s ruling of the Western Regions is a powerful nation’s colonial ruling of weaker nations. However, the history of China has given the feudalist idea in the form of a Chinese world order. Since then, ‘universal unification(天下一統)’, which means the expansion of the territory and the establishment of a multi-ethnic unified nation, has become an important feature of Chinese foreign relations. The purpose of Zhangjian's first dispatch of troops to the Western Regions was military and strategic one to suppress the Xiongnu by pincer attacks with Dayue clan. However, from the second dispatch of troops, the purpose was changed into spreading the virtue of the son the Heaven to the foreign areas where customs were different. The next step was to open roads for exchanges with many countries in the Western Regions and secure regions necessary in terms of strategies. The targets were Loulan, Gushi, Dawan, and Wusun. Therefore, the Han secured the southern road to the Western Regions through attacks on Loulan and Gushi and informed the status of the son of Heaven of the Han to many countries in the Western Regions and obtained the specialties of the Western Regions such as fine steeds with the first and second attacks on Dawan. Marital policies were also used. Wusun, which was dominating the traffic road at that time, was a strategically important country to fight against the Xiongnu forces. The Han tried to conciliate Wusun with a marital policy. The marital policy, which began in the reign of Wudi, continued for a long time even after the death of Wudi and eventually Wusun betrayed the Xiongnu and became a subordinate state of the Han. Originally, Cheshi(Gushi) was the hub of traffic to the Western Regions. After the subordination of Loulan and Wusun to the Han, the Xiongnu was desperate to secure Cheshi because it could dominate various countries in the Western Regions only through Cheshi. The offensive and defensive battles between the Han and the Xiongnu were fierce. The surrender of the Rizhu king xianxian dan who was responsible for Xiongnu’s management of the Western Regions in the third year of Shenjue was a ground-breaking event. The Han not only recovered Cheshi, which had been occupied by the Xiongnu, but also seized the Western Regions at once in place of the Xiongnu. The Han also secured the traffic road going along the southern slope of Tianshan to the west and the road going from Cheshi feudal lord state to the basin of Yili he on the west. The Han installed the Protectorate of the Western Regions in Wulei Castle. The Han’s establishment of the Protectorate of the Western Regions indicates that the Han's attacks on the Western Regions succeeded decisively and the Han became to dominate the Western Regions. Thereafter, the Han has managed the subordinated countries with its own idealized feudalist idea termed Chinese World Order. The Kings and major government officials of the countries under the jurisdiction of the Protectorate of the Western Regions received approving seals given by the Han’s Royal Court. The five countries, Kangguo, Dayuezhi, Anxi, Jibin, and Wuyishanli, were not subjected to the Protectorate of the Western Regions because they were too far away. In addition, moving nations, which were small nomadic nations that were moving along the water plant and the sheep, were not known where controlled by the Protectorate of the Western Regions. What is important is that the investiture order implemented in the Western Regions at this time became the prototype of Chinese border area policies. The Earlier Han’s ruling of the Western Regions means the expansion of the territory. At that time, the territory was a vast area ranging from the west of Dunhuang to the north of the Pamir Plateau and the Kharakorum mountains and the east and south of Lake Balash. Did the people of the Western Regions willingly accept the rule of Earlier Han? The records about ‘Protectorate General Danqin’, ‘Guju and Tangdou’ and ‘Xuzhili’ made during the period of Wangmang, which is negatively evaluated in the Shishu, indicate that the Han’s rule of various countries in the Western Regions was coercive. Although it does not appear in the records before the Wangmang period, given the conflicts between the Protectorate of the Western Regions and various countries in the Western Regions, it cannot be regarded that the people in the Western Regions willingly accepted the rule by the Protectorate of the Western Regions. Because ‘China’ neglected ‘barbarians’, the rule could not but be coercive and the resultant repulsion was natural.

파산절차에 있어서의 중재합의의 효력과 중재절차

오창석 韓國仲裁學會 2005 중재연구 Vol.15 No.1

Bankruptcy proceedings serve the purpose of the collective satisfaction of the debtor's creditors through the realisation of the debtor's assets and the distribution of the proceeds therefrom. Upon the adjudication bankruptcy, the debtor's right to administer and dispose of the property belonging to the bankruptcy estate shall be vested in the administrator. If a mutual contract was not or not completely fulfilled by the debtor and the other party at the time of the adjudication of bankruptcy, the administrator has right to choose wether to fulfil or terminate the contractual relation. Legal acts that have been conducted prior to the adjudication of bankruptcy and that are detrimental to the debtor's creditors may be contested by the administrator. However, these effects of bankruptcy will have not great influence on the arbitration agreement between the debtor and another party. An arbitration agreement that has been conducted prior to the adjudication of bankruptcy is binding the administrator as an universal legal successor of debtor. Only the arbitration agreement directly disadvantageous to the debtor's creditors may be contested by the administrator. Furthermore, it is not at the discretion of administrator whether or not to submit the dispute to arbitration because an arbitration agreement does not belong under the category of Art. 50 Korean Bankruptcy Act which demands a mutual contract. Arbitral proceeding upon the property of the bankruptcy estate and pending for the debtor as plaintiff or against the debtor as defendant at the date of the adjudication of bankruptcy may be taken up at the given status by the administrator. This leads to a change of the party. If a duly summoned party fails to appear in arbitration court, the arbitrator, if satisfied there is no valid excuse, may continue the proceedings and make the award as if all the parties were present. This may be disadvantagious to the debtor's creditors because the arbitral award have the same effects on the participants as the final and conclusive judgement of the court. Even if there is a change of party on side of debtor to the administrator in bankruptcy, the arbitral proceedings will not be automatically postponed or suspended. The matter of how to proceed is at discretion of administrator, when the parties haven't agree on the arbitral proceedings. He can continue the arbitral proceedings without to grant an adjournment of hearing. However, an arbitration award may be challenged by a party dissatisfied and set aside by the court based upon the misconduct that violates the basic rights of the parties to a fair hearing. The arbitrator must treat the parties equally in the arbitral proceedings and give each party a full opportunity to present his case. The arbitrator, therefore, will carefully exercise his discretion in determining whether to continue the arbitral proceedings or to grant a postponing. In the practice, the arbitral proceedings may be usually postponed to grant due process.

The objective of this study was to investigate the influence of moisture content on the physicochemical properties of the dried ostrich meat. The influence of moisture content was analyzed by measuring texture properties, Hunter color value, pH, water activity, content of soluble protein, and sensory evaluation. The dried ostrich meats were prepared at 60℃ using a hot-wind dryer, and it was packed by vacuum packaging machinery. Tensile strength of sample increased as the moisture content was decreased from 20% to 12%, and the value of it was 60.6 N, 93.2 N and 130.8 N, respectively. This trend also appeared similarly In puncture force of the samples. The dried ostrich meat had the highest lightness, redness, and yellowness at 16% of moisture content. The soluble protein of the samples was appeared a decreasing trend with the drying time, but the pH did not changed. It indicated that the moisture content did not affect the pH of dried ostrich meat. And Water activity of the samples had a value below 0.62 in all the samples tested. It means that the most of microorganism cannot grow in the dried ostrich meat. The sample with 16% of moisture content had prominent sensory properties. The moisture content had a great influence on the quality of dried ostrich meat. Overall, the dried ostrich meat containing 16% of moisture content was rated most desirable among the three-moisture content.

A study on the dynamic behavior of the Korean next-generation high-speed train

Jeon, Chang-Sung,Kim, Young-Guk,Park, Joon-Hyuk,Kim, Seog-Won,Park, Tae-Won Professional Engineering Publishing Ltd 2016 Proceedings of the Institution of Mechanical Engin Vol. No.

<P>This study describes the dynamic behavior of the HEMU-430X, the Korean next-generation high-speed train. The HEMU-430X was initially analyzed using VAMPIRE, a computer program that is used to examine the dynamics of railway vehicles, based on which it was expected to sway strongly at its tail end. This hunting motion was expected to disappear when the position of the yaw damper was changed. The dynamic behavior of the HEMU-430X was assessed in an on-track test performed using the protocols in the EN14363 standard and measuring the carbody, bogie and axle accelerations; the HEMU-430X was found to satisfy the safety criterion. The hunting motion appeared at speeds of 150, 350 and 387km/h, and countermeasures such as changing the position of the yaw damper, installing carbody dampers, and increasing the damping coefficient of the yaw damper installed on the motor car containing the driver's cab were taken in order to reduce the vibrations. Ultimately, the highest test speed achieved was 421.4km/h. Subsequently, it was found that the critical speed tended to decrease with mileage. This was attributed to excessive lateral damping and a revised design was proposed to solve this problem.</P>

6-OHDA가 흰쥐 등쪽솔기핵내 도파민성 신경세포와 별아교세포에 미치는 영향

신경독성물질인 6-hydroxydopamine (6-OHDA)이 중추신경계통 내 도파민성 신경세포에 미치는 영향과 이에 따른 별아교 세포들의 반응을 형태학적으로 규명하고자 본 연구를 시행하였다. 흰쥐의 가쪽뇌실에 6-OHDA를 투여한 후 면역조직화학 염색을 시행하여 광학현미경 하에서 등쪽솔기핵 내 도파민성 신경세포에 나타나는 퇴행성변화와 주위 별아교세포들의 반응양상 등을 경시적으로 제 3일, 제 5일, 제10일 및 제20일에서 관찰하였던 바 아래와 같은 결과를 얻었다. 6-OHDA에 의한 도파민성 신경세포의 퇴행성변화는 약물투여후 제 3일군에서 세포돌기가 팽대되고, 제 5일군과 제 10일군에서는 세포돌기의 소실과 함께 세포체가 위축되었고, 제20일군에서는 세포체가 소실되었다. 또한 6-OHDA에 의해 도파민성 신경세포들의 손상이 진행되면서 별아교세포들의 반응양상은 제 5일에서 대조군에 비해 급격하게 증가하였으며, 제20일에 이르러 최고값을 보였다. 이상의 결과로부터 6-OHDA가 중추신경계통 내 도파민성 신경세포들에 선택적이고 강한 세포독성을 유발하여 퇴행성 변화가 진행되고, 세포 손상이 시간 경과에 따라 진행되면서 주위의 별아교세포들이 지속적으로 증가된 활동을 보인다는 사실을 알게 되었다. This study was designed to clarify the cytotoxic effects of 6-hydroxydopamine (6-OHDA) on the dopaminergic neurons and astrocytes in the dorsal raphe nucleus (DRN), and to investigate neurodegenerative changes by immunohistochemistry. Adult male rats (Sprague-Dawley strain) weighing from 250 to 350 g were used as experimental animals. 6-OHDA (100 μg dissolved in 0.1% ascorbic acid) was injected into the lateral ventricle of the rat brain with the Hamilton syringe. The control rats were treated with the similar volume of 0.1 % ascorbic acid. The rats were sacrificed at the 3rd, 5th, 10th and 20th day, respectively, after the injection of 6-OHDA. The cytotoxicity of 6-OHDA resulted in severe neurodegeneration of the dopaminergic neurons in the DRN. In the 3rd day, the dopaminergic fibers were dilated. In the 5th and 10th days, the dopaminergic fibers were depleted, and dopaminergic cell bodies were shrunken. In the 20th day, the dopaminergic cell bodies were almost completely disappeared. Astroglial reactions induced by 6-OHDA were also observed in the DRN. In the 5th day, astrocytes were significantly increased as compared with that of the control value. The value were reached at its maximum by the 20th day. Based on the present results, it suggests that 6-OHDA may act as a specific neurotoxin to dopaminergic neurons in the DRN, and induce severe neurodegenerative changes. Also, it suggests that the astroglial reaction in the DRN is gradually activated during the neurodegerative changes

Improvement of Thermomechanical Fatigue Life in Nitrogen Alloyed 316 Stainless Steel

Kim, Dae Whan,Han, Chang Hee,Ryu, Woo Seog Trans Tech Publications, Ltd. 2005 Materials science forum Vol.475 No.-

<P>Fatigue tests of type 316 and 316LN stainless steel were conducted at RT and 600ı, 0.8~1.5% strain range for low cycle fatigue (LCF), 300~600ı, 0% strain range for thermal fatigue (TF) and 300~600ı, 2% strain range, in-phase or out-of-phase for thermomechanical fatigue (TMF). LCF, TF, and TMF lives were increased but saturation stresses were decreased with the addition of nitrogen. The higher temperature was the lower TF life at a same temperature change. The minimum temperature change for TF failure was more than 100ı. TMF life was higher at inphase condition than at out-of-phase condition. Fracture mode was transgranular for LCF and outof- phase of TMF and almost transgranular and small intergranular for TF and in-phase TMF.</P>

Intracranial hemorrhage due to preeclampsia in the postpartum woman is rarely documented. Generally, the incidence of stroke is increased during pregnancy and early postpartum. Preeclampsia is considered a main cause of both nonhemorrhagic and hemorrhagic stroke. We present a 32-year-old woman who had intracranial hemorrhage at 5 days postpartum. At admission, her consciousness was semicomatose with elevated blood pressure. Computerized tomography revealed intracranial hemorrhage on right frontal lobe. Additional angiography did not reveal abnormal vascular lesion. Emergency craniectomy with hematoma removal was done. However, the patient showed no recovery and died 2 weeks later. We conclude that postpartum care of preeclampsia is important to prevent intraparenchymal hemorrhage. Relative high risk of stroke during the postpartum period suggests a causal roles for the large decrease in blood volume or the rapid changes in hormonal status that follow a live birth or stillbirth, perhaps by means of hemodynamics, coagulative, or vessel wall changes.
