The gray vibrissae of Korean males(n= 189) between 15 and 75 years old and females(n=111) between 15 and 74 years old whop visited the department of otorhinolaryngology, Konkuk university Chungju hospital during 1996 to 1998, were counted for the purpose of estimating approximate age range in individuals of unknown age. The lowest age appearing gray hairs in both sexes was 15-year-old. The Pearson's correlation coefficient in both sexes was 0.490 (p<0.01). The age appearing gray vibrissae in females was slightly earlier than that of males, however, the differences between right and left sides of nasal cavity were insignificant. This method of counting gray vibrissae would be useful to estimate age range in personal identification together with other methods available until now.

Background and Objectives : Postural orthostatic tachycardia syndrome (POTS) is characterized by excessive tachycardia without prominent hypotension in the upright position. Most of the patients experience symptoms of orthostatic intolerance such as lightheadedness, dizziness, palpitation, nausea, or headache. There were limited POTS cases presenting as syncope thus, we analyzed syncope patients who showed orthostatic tachycardia in tilt table test. Methods : A single center retrospective analysis was done for patients with POTS who developed syncope. We reviewed their clinical records and results of autonomic function tests (sympathetic skin response, heart rate variability test to hyperventilation, heart rate variability test to Valsalva maneuver, 15:30 ratio and blood pressure and heart rate response to tilt table test). Results : There were 13 patients of POTS with syncope. Mean age of onset was 22.3 (14-38) years old. Men were eight and women were five. In autonomic function tests, mean orthostatic heart rate increments were 35.2 beats per minutes (bpm). Mean maximal heart rate within 10 minutes and the time for maximal heart rate were 99.9 (87-128) bpm and 7 minutes, respectively. Mean systolic blood pressure was not changed significantly during tilt table tests but, mean diastolic blood pressure was increased as much as 14.4 (±8.0) mmHg compared with supine position. Conclusions : POTS patients who manifested assyncopal attack showed similar patterns in clinical characteristics and autonomic function tests compared with ordinary POTS reported previously. These suggest that syncope can be one of the leading features of POTS. This preliminary study suggests that structured and controlled studies about POTS and syncope are needed.

The 948 goat sera were serologically tested for ten pathogens including bovine viral diarrhea (BVD), bovine herpes virus type-1 (BHV-1) and parainfluenza virus type-3 (PI-3). By viral neutralizaion test, three pathogens including BVD virus, BHV-1, PI-3 were applied for screening each neutralizing antibody and its titration. Among 948 sera, there were 215 seropositives (22.7%) against BVD virus, 25 (2.6%) against BHV-1 virus, and 161 (17.0%) against PI-3 virus, respectively. In the seropositive cases to BVD virus, provincial prevalence of them were recorded as Gyeongnam(30.8%) for the highest one, while as Jeonbuk (15.8%) and Gyeongbuk(l6.7%) relatively for the lower ones. Among them, higher than 1:8 in antibody titration was classified as 74 cases (34.4%) which were suspected the cycle of its infection in their herds. Among the seropositives to BHV-1, it was relatively lower prevalence rate ranging from 1.7% to 6.7% that those of BVD virus and PI-3, but more importantly they were prevailing across the country. Most of the seropositive cases (42.9%) to PI-3 were classified as 1:4-1:16 in titration, but also distributed all around the country. The prevalence in goats varied according to areas (15.8 to 30.8%). Related to the provincial prevalence of three viral agents in Korean goats, it seemed that three viral pathogens would be directly or indirectly involving in various disorders as primary or secondary causative agents resulting in decreased productivity.

T. Veblen의 經濟思想에 관한 硏究

朴東局 동아대학교 부설 사회과학연구소 1985 사회과학논집 Vol.3 No.-

The purpose of this paper is to study the critique of the Economics of Adam Smith. by Thorstein Veblen, who established the Institutionalism as a peculiar paradigm. We can regard most part of the Veblen's economics to be constructed with the attack on main postulates in the Classical Economics and the criticism to the content and methodology of the marginalism. Under the influence of J.Dewey, Veblen scrutinized the fundamental preconceptions of A. Smith, distinguished between the animistic and the teleological, and remarked that these two were respectively perceived in the different aspects. Smith's animistic disposition Veblen thought, lacked the causality in that smoothly continuing natural process of things and connected the gaps or intermissions in the causal relationship. In the examination on Smith's theory of value. Veblen attacked the teleological bias; Smith's concept of the real value is the value that is conferred to various commodities by economists under the teleological preconceptions. This real value or natural price has no relationship with the value conferred in the real world and with the teleological theory in the discussion of actual valuation process. Smith's teleological preconceptions according to Veblen was exemplified in the normalization of data or conjectural history and the arbitrariness of Smith can be easily found in the discourse on the origin and the use of money. Veblen ascribed these characteristics of Smith's economics to the preconceptions. And he thought that Smith had perceived the concept of human nature to be somewhat hedonistic, and normalized human motives and activities so to be fit to the requirement of the natural order. After Smith, Veblen argued the consistent normalizations of human nature resulted (almost) from the utilitarian philosophy.

남북한 분업생산을 통한 산업협력모델

朴東局 東亞大學校 大學院 2002 大學院論文集 Vol.27 No.-

In this thesis, various aspects of comparative advantage and complementary structure of industries in the North and South korea are first analyzed as a basis of the research in the areas of industrial cooperation between them. Upon this, two model of short-term and long-term industrial cooperation ar scrutinized for feasibility study. Until today, the main direction of the North-South economic cooperation has been the consigned production of processed goods. However, this hierarchical divison of labor between two Koreas has to be changed into a more horizontal division of labor if we want to open the new era of economic coexistence, to build an economic community, and to assist the North's economic growth. It is true that the main direction should focus on the raising industrial competitiveness and efficiency of both North and South Korean economies through the division of production based on the principle of comparative advantage. A more differentiated and elaborated system of production between both Koreas might be needed for that purpose. The short-term cooperation model discussed in this paper emphasizes North Korea's economic needs and South Korea's economic conditions. In specific, North Korea must develop what she needs, that is a sector where North Korea can easily learn and borrow the technical expertise from the South. On the contrary, South Korea must cooperate with the North expecially in the field where an idle production capacity among low growth industrial sectors exist. These sectors include food, medical, fertilizer, textile, clothing, and shoes, which are labor-intensive in nature but give a high level of spill-over effect on employment and production values. The mid-term and long-term cooperation model envisions a technology-intensive sector which requires a huge sum of capital, construction, and installation. The specific areas include communication and information industries, computer, semi-conductor, and such heavy industries as steel, ship-building, and automobile, and finally, an industrial sector of machinery where North Korea itself has long built some production capabilities during its own development course.

所得稅制의 改編方案에 관한 考察

朴東局 東亞大學校 大學院 1993 大學院論文集 Vol.18 No.-

The main purpose of this study is to analyze the current income tax system in Korea and thereby to provide the basis of alternative policy choices. This task seems very important in considering the current debate on the desirability and probability of the "real-name banking system (i.e., financial system of real-name tansaction)." the proposed real-name banking system is now deeply divided by both sides. Preponents of the system argue that it is absolutely necessary to solve the equity problem creatd by the decades-old policies that have placed extra advantages on the rich who often accumulated their wealth by somewhat illegal methods. Income tax system, they argue, is only taking money from those who make live ona small amount of salaries. However, oppenents of the many distorted aspects in the econmomy, for instance, a vast amount of underground financing and an exceedingly high rate on income tax, the new banking system would drive the necessary capital out of market. Our analysis shows that the current income tax system is never realized as the current income tax system intended to do. Therefore, there seems to be a compelling necessity to combine the proposed "real-name banking system" in the overall ibncome tax system. The following alternative routes to improve income tax system can be initiated if we try to get the equity problems solved and at the same time to continue our economic growth: 1) Comprehensive income tax system should be fully expanded, in particular to extract income sources of the undergound hidden economy. 2) The proportion of direct tax among government revenue should be lessened in order to protect the disadvantaged strata of the society. 3) A number of tax-rebate schemes should be changed in the direction of giving tax-break for those disadvantaged. No tax-break should be given before imposing the required tax rate on the income. 4) Some technical advances should be made in order to get the most out of possible incomes. Morality aspect of tax-payers should also be educayed in the process of socialization. 5) the size of tax-breaks for political or "policy reasons" should also be decreased to get the equity among people.

이동활,이종대,전진혁,박노국,류시옥,이태진 嶺南大學校 工業技術硏究所 2003 工業技術硏究所論文集 Vol.31 No.2

This study was performed to manufacture tungsten carbide from CO reduction- carburization of WO₃using zeolite-NaX catalyst. Zeolite-NaX catalyst could improve the reduction property of WO₃. Moreover, zeoite-HX and KX catalysts also improved the reduction property of WO₃. This improvement of reduction property leaded to the decrease of reaction temperature. The size of WC particle was 50∼60 nm at 650 ℃ for 10h. From these results, it is concluded that the various zeolite X catalysts could be used for the reduction-carburization of W0₃ as the catalysts.
