정동원 ( Dong Won Jeong ),한종호 ( Jong Ho Han ) 한국물류학회 2012 물류학회지 Vol.22 No.2

물류산업은 경제 발전에 중요한 역할을 담당하며, 산업경쟁력과 국가경쟁력을 결정하는 중요한 요소로 작용하고 있다. 본 논문에서는 산업연관분석을 이용하여 물류산업의 국민경제적 파급효과를 분석하고자 한다. 먼저 수요유도형 모형을 이용하여 물류산업의 타 산업 생산유발효과, 부가가치 유발효과, 취업유발효과를 살펴본다. 다음으로 상대적으로 복잡성 때문에 잘 사용되지 않았던 공급유도형 모형 및 레온티에프 가격모형을 적용하여 물류산업의 공급지장효과 및 물가파급 효과를 살펴본다. 이러한 분석은 모두 물류산업을 내생부문이 아닌 외생부문으로 다룸으로써 물류산업을 중심으로 이루어지게 된다. 주요 분석결과를 요약하면 다음과 같다. 물류산업의 1원 생산은 타 산업의 생산을 0.5104원만큼 유발하며, 타산업의 부가가가치를 0.1722원만큼 유발한다. 또한 물류산업의 10억원 생산은 타산업에서 2.2554명의 취업을 유발한다. 한편 물류산업에서 1원의 공급이 이루어지지 못할 때, 타 산업에서는 0.9387원의 생산차질이 발생하여 공급지장효과가 제법 큰 편이다. 마지막으로 물류산업의 가격이 10& 상승했을 때, 국민경제 전체적으로 미치는 물가파급효과는 0.0276%로 분석되었다. The logistics industry in Korea plays a major role in the national economy development and to make decision nation and industrial competitiveness, This study attempts to examine the economic impacts of the logistics industry using an inter-industry analysis, Specially, the study investigates production-inducting effect, value added inducing effect, and employment-inducing effect of the logistics industry based on demand-driven model. Moreover, the study deals with supply shortage effect and sectoral price effect by using supply-driven model and leontief price model, respectively, which have been rarely used because of their complications involved in computaiton. These analyses pay particular and close attention to the distribution industry by taking it as exogenous rather than endogenous. Some interesting findings emerge from the study. First, the production of 1.0 won in the logistics industry induces the production of 0.5104 won and the value-added of 0.1722 won in other industries. Second, the production of 1.0 billion won in the logistics industry causes the employment of 2.554 persons in other industries. Third, the supply shortage of 1.0 won in the logistics industry disables other industries to produce 0.9387 won. Finally, an increase of 10% in price level of the logistics industry raises the overall price level by 0.0276%.

N/A This study employed 11 university soccer players for assessing anaerobic capacities related to ATP-PC and/or lactate system. It was investigated correlation among anaerobic capacities from Critical Power test, from Wingate test, and from Isokinetic test. Also, the study investigated regression formula which could expect anaerobic reserve(AR) from variables measured in Wingate and Isokinetic test. There were significant but intermediate correlation between AR and WIN5, (r= .62, P< .05) and WIN30(r= .64, P< .05). There was no statistically significant but intermediate correlation between AR and WIN10 (r= .52, P> .05). The study used stepwise method for multiple regression by Wingate variables to produce AR. The result showed that WIN30 had significant effect and indicated regression formula (Y= 1.3323(WIN30)-14737.758) to explain 41.2% variation of AR. Stepwise method was done for multiple regression on Isokinetic variables to produce AR`s inferred possibility by extensors TW of 60˚ /sec as regression (Y= 10.6737 (TW)+2083.9403) explained 42.9% variation of AR. In the correlation between measured variables of Wingate and Isokinetic extensors there was no significance of intermediate correlation in 60˚ /sec PT and WIN5(r= .53, P> .05) and in TW and WIN5(r= .56 P< .05) statistically. Also, There was significance of intermediate correlation in PT and WIN10 (r= .65, P< .05), no significance in TW and WIN10 (r= .57, P> .05), in PT and WIN30(r= .58), and no significance in TW and WIN30(r= .46, P> .05). In the correlation between measured variables of Wingate and Isokinetic extensors, there was significance of intermediate correlation in 180˚ /sec PT and WIN10 (r= .69, P< .05) and significant correlation in Isokintic 180˚ /sec PT and WIN30(r= .65, P< .05). The data suggested that anaerobic reserve assess true anaerobic ability not including the energy component of anaerobic glycolyses. Also, the study provides preliminary data on the anaerobic abilities in university soccer players as assessed by the Critical Power test, Wingate test, and Isokinetic test.

中風의 痰因設에 대한 考察

정완우,이원철 동국대학교 한의학연구소 1999 東國韓醫學硏究所論文集 Vol.8 No.1

痰飮은 疾病의 경과중에 발생되는 病理的인 産物로, 痰飮 자체가 疾病의 原因이 될 수 있으며, 疾病의 결과물로 생길수도 있다. 저자는 <內經> 이후의 歷代 文獻 考察을 통해 痰飮이 中風의 발생에 미치는 영향과, 아울러 痰飮과 津液의 관계, 津液과 腦의 관계, 痰飮과 瘀血의 관계 등을 연구하였다. 痰飮은 七情의 不調, 精氣虧損 ,飮食失調, 外感六淫, 體質的 素因 등의 因子로 인해 발생되어 熱痰, 風痰, 濕痰으로 化하고 臟腑ㆍ經絡에 鬱滯하여 氣血의 순환을 막아 中風을 유발하게 된다. 한편 痰飮은 津液으로부터 형성되고, 津液은 氣滯, 火鬱, 寒凝의 病理過程을 통하여 痰飮으로 轉化되며, 腦는 津液의 滋潤과 充??에 의해 그 기능을 유지한다. 따라서 津液이 痰飮으로 轉化되어 氣血運行을 막으면 脛에도 영향을 미칠수 있을 것으로 사료된다. 痰飮과 痰血의 관계를 보면 痰飮은 瘀血과 病理變化에 있어 밀접한 관계에 있으며, 中風發生에 있어서 痰飮이 瘀血에 先行하거나, 瘀血이 먼저 형성된 후에 痰飮이 형성되거나, 혹은 서로 兼하여 발생할수도 있다. "Dan-eum(痰飮)" is the pathological product which is developed in the progress of disease. "Dam-eum" itself can be an etiological factor and id developed as consequential products on diseases. This study is investigated into "Dam-eum" and stroke through the literature since the book, "Hwangje-naekyong(黃帝內經)" and the results are as follows. 1. "Dam-em" is the patholofical product, which is changed into "Yol-Dam(熱痰)", “Pung-dam(風痰)" and "Seub-dam(濕痰)", owing to the disorders of diet and "Chil-jung(七情)", infirmity of "Jung-ki(精氣)", "Oi-gam-yuk-em(外感六淫)", constitutional factors and so forth. In is blocked up "Jangbu-Kyongrak(臟腑經絡)" and brings about stroke with the disorders in circulation of "Gi-hyul(氣血)". 2. "Dan-em" is formed out of "Jin-aek(津液)", which is changed through the pathological process of "Gi-cheh(氣體)", "Hwa-yoi(火鬱)" and “Han-eng(寒凝)", In the meanwhile, the brain keeps its function with nutrition of "Jin-aek", If "Dam-em" isformed by deficiency and cirticulation disorders of "Jin-aek", it can affect the brain 3. "Dam-eum" is correlated with "Eo-hyul(瘀血)", and the pathological trunsformations. In the attack of stroke. "Dam-eum" precedes "Eo-hyul", in reverse or the two are concurrent with each other

Compared to conventional dc motors having the combination of commutators and brushes, a brushless DC (BLDC) motor is one of the highly efficient motors due to its electrical commutation without a brush, and this feature allows the BLDC otor to be more suitable for an application requiring no maintenance due to mechanical wear between a commutator and a brush. Also, the BLDC motor has a few benefits over both a dc motor and an induction motor such as high dynamic response, high efficiency, logn life span, and low noise in wide speed-torque region. This paper investigates the variation of voltage induced in phase windings in a BLDC motor in several cases with respect to stack length, steel grade, and coil material. This study is numerically conducted and it is verified from the theoritical point of view by comparing the result of simulation with that of experimental measurement.

Air void systems in hardened concrete has an important influence on concrete durability such as freeze-thaw resistance, water permeability, surface scaling resistance. Linear traverse method and point count method described at ASTM are the routine analysis of the air void system that have been widely used to estimate the spacing factor in hardened concrete. Recently, many concretes often have a spacing factor higher than the generally accepted 200-250㎛ limit for the usual range of air contents. This study is proposed to estimate the plane spacing factor by calculation of simplicity. The plane spacing factor need two parameters that are air content and numbers of air voids in the hardened concrete. Those obtained from the standard air-void system analysis of the ASTM C 457. The equation is valid for all values of paste-to-air ratio because the estimation of paste content is unnecessary at the using ASTM C 457. The plane spacing factor yields a similar estimate of the standard spacing factor.

전기충격요법 사용에 관한 정신과의사의 견해 및 실시현황

정환증,변원탄 大韓神經精神醫學會 1983 신경정신의학 Vol.22 No.4

한국 정신과 의사 211명의 전기충격요법에 관한 의견을 다음과 같이 요약할 수 있었다. 1. 735가 치료방법으로서의 전기충격요법을 찬성하는 태도였고, 찬성하는 가장 큰 이유로서는 적응증만 잘 고려된다면 일반적으로 우수한 효과를 볼 수 있다는 것이었다. 그러나, 그 실제적인 사용에 있어서는 다수에서 조심스러운 태도를 보이고 있었고, 어떤 견해에 있어서는 미국의 정신과 의사들보다 훨씬 더 소극적인 태도를 가지고 있었다. 2. 전기충격요법의 적응증에 관한 한 역시 예상한 바와 같이 주요 우울장애, 조증 흥분, 정신분열증의 순으로 찬성하는 경향이 많았고, 이 방법을 선택한 이유로는 '응급처치로 시행하거나' 다른 치료방법에 실패했거나' '보다나은 결과를 얻기 위한 병용 치료로서 선택' 등이 가장 많았다. 3. 정신분열증에서의 전기충격요법은 사용의 한계를 나타내고 있었다. 4. 시행 이전의 동의나 시행 전 감사에 대해서는 비교적 엄격한 태도를 유지하고 있으나, 연성 전기충격요법, 편측 전기충격요법의 활용은 적었으며, 강력 또는 유지 전기충격요법 역시 시행율이 낮은 편이였다. 시행빈도는 79%가 주2-3회를 실시하는 것으로 나타났고, 향정신약물을 사용하던 환자에서 전기충격요법을 시행한 경우, 대체로 약간의 약물 감량을 실시하는 것으로 나타났다(59%) 5. 전기충격요법 시행 이후의 합병증으로는 골절이나 탈구, 직업 수행 능력에 영구적인 장애, 자발적인 경련 발작 등이 예상외로 많아 합병증은 역시 소홀히 할 수 없는 문제임을 나타내 보였으며, 전기충격요법 이후 24시간이내 사망을 경험한 예가 6경우가 있었다. The authors of this suveyed the opinions of 211 Korean psychiatrists about the use of Electoconvulsive Theraoy(ECT). The results of the survey are summarized as follows; 1. ECT was accepted with a favorable attitude by 73% of the psychiatrists surveyed. The most common reason for agreement was that if indication is followed the ECT generally produces excellent results. But in actual clinical practice most Korean psychiatrists are hesitant in preforming the ECT and have a somewhat less active attitude towards ECT than psychia trists in America. 2. The major indications for theuse of ECT were major depression, manic excithment and schizophrenia in the order of their frequency. The main reasons for the selection of ECT as a therapeutic tool were emergency therapy, when all other treatment methods have failed and as a combined treatment that can. 3. The use of the ECT for the treatment of schizophrenia was very limited for a few selected cases. 4. Korean psychiatrists showed relatively rigid adherence to obtaining the consent before ECT and the preoperational work-up. The softening and unilateral ECT had received little use in Korea and a similar tendency was shown towards intensive and maintenance ECT. Most psychiatrists(79%) tended to use the ECT 2 or 3 times a ewek with a majority of their patients. In cases where the ECT was used in concomitant with antipsychotic drug therapy, there showed a tendency for a slight reduction in drug dosages during the ECT. 5. Post-ECT complications and/or adverse effects were fracture, dislocation, premanent disability in occupational performane and spontaneous seizures etc. Occurrences of above complications seem to be mlre than expected in this study and this was not negligible. A total of six patients were known to habe expired within twenty-four hours after ECT.

勤勞者들의 勞使關係에 關한 意識調査 및 檢定的 分析

鄭原圭 釜山敎育大學 1981 부산교육대학 논문집 Vol.17 No.1

The study is to aim at finding the problem by surveying and analyzing the constructure of consciousness on the relations between labour and management of Korean labours under such conditions as the right to labour restricted partially, and at finding a pl an for the desirable, coopeative relations between labour and management. The results and study surveyed and analyzed are as follows: 1. Manual labours don't have an elementary knowledge on the relations between labour and management because of their shortage of education an enlightment and as a result, they misundesrtand a labour union and a council of labour union necessary for them. Therefore it is necessary for us to educate and enlighten them in order to shape the desirable, cooperative relations between labour and management through dialog. 2. There is no tendency to work in close cooperation between labour and management because labours don't know well the principle and idea of their company owing to the lack of communication for employees of the company itself and the negligence of the management of the relations between labor and management. The policy that appeals to labours and makes them understand the company clearly should be shaped by employer. 3. Many labours hope the paternalistic relations between labour and management and be live that they can get much benefit through the positive participation and adjustment of the nation in order to keep the desirable relations between labour and management. This means that they believe only the nation, neither the labour union nor the ente rprise. The self-control, cooperative system through dialog will be led by the gove rnment but it is premature to carry out the plan. 4. Labours are conscious that human relation in the enterprise is lacking and the company is not concerned with their welfare. The company should be much concered with the improcement of human rlation and welfare as much as possible. 5. Korean labors are so thorough in the consciousness of nation security that they take it for granted that their lavour movement is strongly controlled by nation from the view point of reality of Korea, and desire a social peace and enployment peace. 6. The majority(70.6%) of labours are conscious that New Community Movement in Factory is essential and must be developed more. But some (29.4%) of them think it to be profit for the company and it is significaut for them to think it to be uninteresting. Therefore it is proved that some enterprises can;t take the interest and support of some employees because the fruit-bearing of New Community Movement in Factory can't meet the earnings and welfare of employees according to the rational distributions in some enterprises and there is tendency to misunderstand this movement as if it is labor service of labours. Therefore, the principle that the enterprise will be develope by returning the results of New Community Movement in Factory to the employees should be planed and carried out. It is believed that the consciousness of sharing their fortune with each other is shaped and cooperative system of the relation between labour and management indigenous to korean is shaped.

George Bernard Shaw의 Social Drama硏究 : 作品 Major Barbara를 中心으로

鄭元植 건국대학교 1987 論文集 Vol.24 No.1

George Bernard Shaw(1856-1950) has been hailed as the greatest British dramatist since Shakespeare. His drama is essentially drama of ideas ; the elements of melodrama, personal conflict, suspense, and Wit are intended merely to support and convey to intellectual content. One of the fruitful mysteries of Shaw's drama is why his special distortions in character-drawing should provoke such different reactions among his readers. His drama style is polemical, his talent is devoted almost entirely to demonstrating the wrongness of the opposing cause. At one tome an active member of the Fabian Society, Shaw remained throughout his career an advocate of public ownership of resources and of a more equitable division of social wealth. He is antagonistic toward the capitalistic class not because he believes it to be inherently wicked, but because he believes it must be disenfranchised before any worthwhile social amelioration can take place. Surely Shaw is liberal and socialist, but of a peculiar cut. He cannot be assigned to any literary school, potitical party. or philosophical movement ; his ideology is highly individualistic, although no part of it is totally unique. Through the medium of his work Shaw always continued to explore the religious consciousness and to point out societys complicity in its own evils. His work "Major Barbara" is a drama which the story of the daughter of a wealthy munitions manufacturer who johns the Salvation Army to defy her father, preaches the still timely lesson that poverty is the root of all evils. In his work "Major Barbara"(written and performed in 1905), Barbara Undershaft, a major in the Salvation Army, discovers that her estranged father, a munitions manufacturer, may be dealer in Death, but that his principles and practice, however unorthodox, are religious in the highest sense, white those of the Salvation Army require the hypocrisies of often-false public comfessien and the donations of the distillers and the armorers against which it piously inveighs. and Undershaft, father of major Barbara, is simply a man who, having grasped the fact that poverty is a crime, knows that when society offered him the alternative of poverty or a lucrative trade in death and destruction, it offered him, not a choice between opulent villainy and humble virtue, but between energetic enterprise and cowardly infamy Shaw. shows in this drama that he used his dramas as a means of public thinking on the ideological conflicts of his time. Consequently the central conflict of the drama is between the ideas of Andrew Underashft on the one hand, and the ideas of the whole society, represented by his whole family on the other. In these circumatances I think it is greatly valuabe to examine and study what happened in the work "Major Barbara" for social reform.

환경기초시설의 인 기준 강화에 따른 팔당호 유입 수계의 수질개선 효과분석

정원구,한영한,임재명 江原大學校 産業技術硏究所 2010 産業技術硏究 Vol.30 No.B

The influences on water quality of each river by effluents from environmental facilities located in 14 unit watersheds of North- and South-Han River, and Gyungan-cheon were analyzed. Also, the water quality modeling for study area was carried out to analyze the improvement effect of water quality by the strengthening of T-P effluent standard of environmental facilities. For the calibration and verification of model, water quality data and effluent loading calculated for 2006 were used. Data of low water period were used for calibration, and normal water period for verification. The results of calibration and verification were well matched with the real water quality dataset of revers. Also, the validity of the results were estimated using RI(Reliability Index) method. When the T-P effluent standards for environmental facilities were strengthened, T-P concentrations were predicted to improve from 0.025㎎/ℓ to 0.023㎎/ℓ in the outlet location of North-Han River, from 0.056㎎/ℓ to 0.040㎎/ℓ for South-Han River, and from 0.233㎎/ℓ to 0.146㎎/ℓ for Gyungan-cheon. Also, the T-P concentrations of tributaries including Jojong-cheon, Dal-cheong, Sumgang, Chungmi-cheon, Bokha-cheon, Heuk-cheon, and Wonju-cheon were predicted to improve from 0.063㎎/ℓ to 0.010㎎/ℓ, from 0.091㎎/ℓ to 0.053㎎/ℓ, from 0.199㎎/ℓ to 0.100㎎/ℓ, from 0.168㎎/ℓ to 0.148㎎/ℓ, from 0.186㎎/ℓ to 0.105㎎/ℓ, from 0.019㎎/ℓ to 0.013㎎/ℓ, and from 0.822㎎/ℓ to 0.236㎎/ℓ, respectively.
