Welfare Effects of Voluntary Import Expansion : Using Cournot Model 쿠르노 모델을 이용하여

Sim, Sung-Hoon 慶州大學校 2005 論文集 Vol.18 No.1

그 동안 수입할당제(import quota)에 대한 대안으로써 자발적 수출제한(voluntary export restraint)이라는 정부의 정책에 관하여 활발하게 연구되어 왔으나, 자발적 수입확대(voluntary import expansion) 정책에 대한 연구는 그리 활발하지 못하였다. 본 연구는 단순한 쿠르노 모델을 이용하여, 자발적 수입확대정책을 채택한 나라의 후생 효과(welfare effect)에 대한 몇 가지 이론적 결론을 도출하였다. 첫째, 자발적 수입확대 정책을 채택한 나라는, 자유무역의 경우에 비하여 가격을 상향하는 전략을 채택함으로써 이익을 극대화 할 수 있음을 보여 준다. 둘째, 자발적 수입확대가 매우 클 경우에는 후생효과가 불확실하다는 결론이 도출되었다. 셋째, 자발적 수입확대와는 다르게 자발적 수출제한은 가격경쟁에 의하여 한 나라를 시장에서 퇴출시키지 못한다는 것을 보여 주었다. 또한 본 연구는 한 나라의 경제 규모가 매주 작은 경우뿐만 아니라, 그 규모가 매우 큰 경우에도 그 나라는 자발적 수입확대를 무시할 수 있다는 점을 이론적으로 보여 준다.

Hong, Sung-Hoon, and Chang-Kook Suh. 2004. Underlying represen-tation in Geminates: from an OT perspective. Studies in Phonetics, Phonology and Morphology. 10.1. 129.144. This research has examined the status of Underlying Representation (UR) in Optimality Theory focusing on the representation of consonant geminates. For this purpose, we have examined geminate/singleton alternation in Ponapean employing Lexicon Optimization (LO), an algorithm proposed to select a UR among multiple inputs. We have seen that simple application of LO is problematic in singling out a UR for the case of alternation. This leads us to the version of LO that is performed on the paradigms, rather than on an individual forms (Tesar and Smolensky 1996, 2000, Inkelas 1995, 1998). After a thorough implementation of LO, we have found that the URs are simply identical to the input forms; geminate UR for the alternating case and singleton UR for the nonalternating case. Further, it was shown that a unique underlying representation of geminates, regardless of their positions in which they occur, can account for the exceptional geminate behaviors.

Underspecification in Optimality Theory: Vowel Harmony in Classical Manchu

Sung-Hoon Hong 한국음운론학회 2002 음성·음운·형태론 연구 Vol.8 No.2

Hong, Sung-Hoon. 2002. Underspecification in Optimality Theory: Vowel Harmony in Classical Manchu. Studies in Phonetics, Phonology and Morphology 8.2. 323-350. This paper addresses some important issues raised by A TR harmony in Classical Manchu, formerly treated as front/back harmony. Here, the front high vowel [i] is totally inactive with respect to the harmony: it is transparent to the harmony, and further, it does not initiate the harmony. I will show that these properties of [i] will be properly explained if we allow underspecified [i] as an option for inputs and output candidate forms. Allowing underspecified [i] in fact accords more with basic notions of Optimality Theory (OT) such as Freedom of Analysis and Richness of the Base than the analyses that do not tolerate this possibility. I will further show that once we allow underspecified [i], its selection in output candidate forms or in input forms is totally governed by OT principles such as constraint interaction and Lexicon Optimization, respectively.

The diagnostic requirements were suggested and explained regarding the systems of differentiation of symptoms and signs in the second year study of standardization and unification of the terms and conditions used for diagnosis in oriental medicine. The systems were as follows; - differential diagnosis according to condition of body fluid, differentiation of syndromes according to the state of qi and blood, differential diagnosis according to relative excessiveness or deficiency of yin and yang(氣血陰陽津液辨證) - differentiation of diseases according to pathological changes of the viscera and their interrelation - analyzing and differentiating of febrile diseases in accordance with the theory of the six channels(傷寒辨證) The individual diagnosis pattern was arranged by the diagnostic requirements in the following order : another name(異名), notion of diagnosis pattern, index of differentiation of symptoms and signs(辨證指標), the main point of diagnosis, analysis of diagnosis pattern(證候分析), discrimination of diagnosis pattern(證候鑑別), a way of curing a diseases(治法), prescription(處方), herb in common use(常用藥物), diseases appearing the diagnosis pattern(常見疾病), documents(文獻調査). This study was carried out on the basis of the Chinese documents and references.

Prediction of Retained Austenite Fraction in Quenching-and-Partitioning (Q&P) Steels Using the Gibbs Energy Balance Approach

Seong Hoon Kim,Ji Hoon Kim,Jae Hoon Lee,Dong‑Woo Suh,Jae Sang Lee 대한금속·재료학회 2022 METALS AND MATERIALS International Vol.28 No.9

Prediction of retained austenite fraction is quite important in designing advanced high strength steels since retained austeniteis the source of transformation-induced plasticity. The present study investigates the phase constitution of a medium-carbonQ&P steel by comparing various approaches to the transformation stasis of bainitic ferrite and applying them to the partitioningprocess. Among them, the modified GEB approach gave the best agreement with the experimental observation, includingthe effects of heat-treatment condition and chemical composition on phase constitution. This indicates phase transformationduring partitioning can be effectively described by the physics of Gibbs energy balance approach.

Background : Bleeding after endoscopic procedure of the stomach carries an increased risk of morbidity and mortality. In case of oozing hemorrhage, not in active hemorrhage, powdered sodium alginate may play a role in control of bleeding with convenience. Therefore, we evaluated the clinical effect and efficacy of sodium alginate powder in upper G-Ⅰ bleeding. Methods : Forty-five patients who had upper G-Ⅰ bleeding after endoscopic procedure were enrolled in this study. Twenty-five patients of them were managed by the application of powder preparation of Sodium alginate(ALTO). The others were observed without treatment. The next day, we performed endoscopy in all patients to ascertain the hemostasis. Results : Of 25 patients managed with Sodium alginate, only two patients(8%) had bleeding (hemostatic rate : 92%), On the other hand, of 20 patients who did not receive any treatment, 3 patient(15%) had bleeding (hemostatic rate : 85%). There was no statistical difference between the two groups(p>0.05). Using other endoscopic procedure, We successfully treated the patient who continued to bleed. Conclusion : We evaluated the effect of the spary of sodium alginate on oozing hemorrhage. Although there was no statistical significance in our study, it seems that the spray of sodium alginate may be a useful method for the prevention of bleeding after endoscopic procedure.

양상훈, 김종식. 야외운동기구를 이용한 운동프로그램이 노인들의 활동체력, 대사증후군 위험인자 및 염증인자에 미치는 영향. 운동과학, 제23권 제3호, 229-240, 2014. 본 연구는 여성노인 65세 이상 16명을 대상으로 8주간의 야외운동기구를 이용한 운동프로그램 참여가 활동체력, 대사증후군 위험인자 및 염증인자에 미치는 영향을 규명하였다. 활동체력의 경우 악력은 유의한 차이가 없었으나 하지근력과 유연성은 운동 후 유의하게 증가한 것으로 나타났다. 대사증후군 위험인자의 경우 HDL-C는 운동 후 유의하게 증가하는 것으로 나타났으며, glucose는 유의하게 감소하는 것으로 나타났다. 허리둘레, 수축기 혈압, 이완기 혈압, TG는 유의한 차이가 없었다. 염증인자의 경우 CRP, TNF-α 모두 운동 후 감소하는 것으로 나타났으나 유의한 차이는 없었다. 결론적으로 야외운동기구 운동프로그램은 하지근력, 유연성 강화와 HDL-C 증가, glucose 감소의 연구결과를 보았을 때 더 다양한 야외운동기구를 이용한 운동프로그램을 개발하고 지속적으로 운동의 효율을 높여간다면 노화를 지연시킬 뿐만 아니라 각종 질병을 방지하고 건강을 유지시키는 효과를 기대할 수 있을 것으로 사료된다. Yang, Sang-Hoon, Kim, Jong-Shik. The Effects of Exercise Program Outdoor Exercise Equipment on Activity Fitness, Metabolic Syndrome Risk Factors and Inflammatory Factors in the Elderly. Exercise Science, 23(3): 229-240. 2014. This study is for observing the influence of exercising in outdoor exercise facilities for 8 weeks on activity fitness, risk factors of insulin resistance syndrome and inflammatory factors in 16 females who are aged 65 years or older. The major results on this analysis are as follows: In parameters for activity fitness, there was no significant difference in grasping power but a significant increase in strength of lower limb muscles and flexibility after exercise. For risk factors of insul in resistance syndrome, there was a significant increase in HDL-C after exercise with a significant decrease in gl ucose. There was no significant difference in waist l ine, systol ic bl ood pressure, diastol ic bl ood pressure and TG. For inflammatory factors, there was a decrease in CRP and TNF-α after exercise with no significance. In conclusion, the results showing positive effects on physical fitness of lower limb muscles and physiological markers including HDL-C and glucose indicates that elderly women exercising in outdoor exercise facilities may have benefits of antiaging effect, prevent various diseases and stay healthy if efficiency of exercise using outdoor exercise facilities is continually improved in a variety of training programs.
