The objective of this study is to reduce the gloss of thick denier PET yarn. Pure PET yarn exhibits considerable shine. Since wig fiber is thicker than clothing fiber, it is not easy to reduce the gloss. In this study, three types of inorganic particles, namely, $TiO_2$, $SiO_2$, and talc were added to the PET yarn to test the tendency of gloss reduction. Moreover, the gloss variation was tested according to the cross section of the fiber, the spinning temperature, and the draw ratio. Owing to the addition of the particles, the crystallization of PET was promoted and the crystallization of talc was exceedingly rapid. The manufactured yarn with the added $TiO_2$ was the least glossy. The gloss of the fiber decreased in the following order: star shape > circular shape > peanut shape. The spinning temperature had no effect on the gloss, however, the gloss of the fiber increased as the draw ratio increased.

비싼 임금이 주도한 동반성장: 이론과 사례

임종철 서울대학교 경제연구소 2023 經濟論集 Vol.62 No.1

“나는 방학 때면 늘 몇 개 도시 가장 가난한 사람들이 사는 곳을 찾아갔었다. 그리고 그들이 살고 있는 뒷골목길을 하나하나 걸어다니며 가장 가난한 사람들 얼굴을 살펴보았다. 그런 다음 나는 내 힘이 닿는대로 철저하게 경제학을 연구하기로 결심했다.”

경제발전하의 안정화정책 : 제1차 경제개발 5개년계획의 경험에 비추어 With Respect to the First-Five Year Economic Plan

임종철 성균관대학교 사회과학연구소 1968 社會科學 Vol.7 No.1

To maintain economic stability and sustained economic growth is the main objectives of our economic society. However, it is hard to expect that these goals can be always realized any time and anywhere. In fact, economic policies to implement these two objectives seem to be highly complementary by its intrinsic nature, yet sharply conflicting each other in practice. Our experiences indicate that some country can attain a rapid stable growth; some country, by intensifing these conflicts, yet obtain a rapid growth of an economy. It is also learned that in some countries, the - primary emphasis is placed on stabilization policies at the expense of economic growth. Amongst these alternatives of economic policies, what is the best one depends entirely on the social welfare function and the ultimate value towards it taken by decision makers of economic policies. Nevertheless, a generalization is easily made that stabilization policies are the primary goal of economic policies where wealth is so much accumulated in advanced economies while the $quot;growth-first$quot; policies are the primary targets in developing nations. Such a generalization might seem to be justifiable. However, our experiences indicate that such an generalization is, in fact, extremely difficult one to make. One of the main reasons is that unstabilizing factors are expected to be inherent in developing countries more than in advanced countries, because of the fact that there exists growth potentials in underdeveloped economies. Such inherent unstabilizing factors are as follows. 1. Unstabilizing effects are easily expected when the pattern of wealth composition of an economy is changing. 2. When investment demand is increasing, inflationary pressure might be taken place. 3. There is a widening gap between the living standard and increase in the level of productivity. 4. In a rapidly growing economy, structural changes are easily expected to be occurred. 5. When development plans are formulated with regionally bias within an economy, this might lead to create unstabilizing effects. 6. If the government takes discretionary policies of development plans, this leads to create unstabilizing effects in an economy. Therefore, unless the above effects were completely eliminated or minimizing such effects inherent in a process of economic development, self-sustained economic growth of an economy can hardly be expected. Let us consider stabilization policies necessary to eliminate the above effects. 1. When the pattern of wealth composition of an economy is changing, the government should control investment activities. Therefore, selective investment-control policies are required to stabilize an economy. 2. When an economy is under inflationary pressure, basically caused by an increase in investment demand, expansionary policies should be curtailed by the government to use monetary and fiscal measures properly. 3. In order to wipe out the gap between the living standard and the increase, in the level of productivity minimum standard of living on the part of wage-earners should be maintained. 4. In fact, structural change of an economy is primarily concerned with long-run aspects of economic development. Therefore, the scales of operation in medium-size industries should be changed in order to be optimized. 5. In order to eliminate the regional difference of development it is necessary for the government to carry out decentralization policies of development so that potentiality of medium size industries should be fully utilized. Income equalization policies through fiscal measures are also necessary to increase effective demand of the economy as a whole. 6. In order to mitigate discretionary policies taken by the government, policy criteria should be rationalized in line with economic reasoning. Once a criteria is specified, policy instruments reqnired for the criteria should be used efficiently. Above all, it is needless to say that a set of development projects and policies should be coordinated. I have pointed out the measures necessary to maintain a stable growth in the context of Korean economy. In underdeveloped countries, to make realization of all such measures into effect can be hardly expected, because of lack of administrative techniques of government in underdeveloped countries to implement such measures of development planning. Yet, efforts trying to pay to implement such measures by our government will certainly contribute to maintain economic stability and economic growth of our economy.

A Blockchain is a type of distributed ledger system that consists of a large number of nodes. A block is a container in which transactions are included, and the transactions can be recorded in chronological order by chaining blocks. To work properly, it is essential that the nodes in the Blockchain system have the same image of the chained-blocks. Blockchain systems use various types of consensus algorithms to achieve the same states among the nodes, and the fundamental elements in these algorithms are proof of work and the main chain selection policy, particularly in permissionless Blockchain systems. However, consensus algorithms for permissioned Blockchain systems can be completely different from those of permissionless blockchain systems. In this paper, we overview the basic working mechanism of consensus algorithms, and briefly introduce a few that are currently being applied.

Risk factors of emergence agitation after general anesthesia in adult patients

임종철,김정아,홍정인,박상융,이종환,정찬종 대한마취통증의학회 2016 Anesthesia and pain medicine Vol.11 No.4

Background: Emergence agitation (EA) is one of the most common complications after general anesthesia. The goal of this retrospective study was to determine the risk factors of EA in adult patients who underwent general anesthesia. Methods: We retrospectively investigated the medical records of 5,358 adult patients who stayed in the postanesthesia care unit (PACU) of our hospital after general anesthesia during the 1-year period from January 2014 to December 2014. Psychological and behavioral status in the PACU was determined by the Aono four-point scale. Grade of 3 or 4 were considered as manifestations of EA. Multiple variables assessed EA risk factors. Results: Two-hundred-forty-five patients (4.6%) developed EA. In multivariate analysis, male gender (OR = 1.626, P = 0.001), older age (OR = 1.010, P = 0.035), abdominal surgery (OR = 1.633, P = 0.002), spine surgery (OR = 1.777, P = 0.015), longer duration of anesthesia (OR = 1.002, P < 0.001), postoperative nausea and vomiting (OR = 20.164, P < 0.001) and postoperative pain (OR = 3.614, P < 0.001) were risk factors of EA. Conclusions: Male gender and older patients were risk factors of EA after general anesthesia in adult patients. Careful attention is needed for patients who receive abdominal or spine surgery, and who receive prolonged anesthesia. Adequate postoperative analgesia and antiemetic therapy should be provided to reduce the incidence of EA.
