Multi-Parameter Maximal Operators Associated with Finite Measures and Arbitrary Sets of Parameters

Heo ,, Y. Springer Science + Business Media 2016 Integral equations and operator theory Vol.86 No.2

<P>In this paper we examine various singular maximal operators, extending the class of operators which have been studied extensively in the past. It extends work that has been done in the one-parameter to the multi-parameter setting. We obtain the -boundedness properties of the multi-parameter maximal operators associated with finite measures and arbitrary sets of parameters by assuming some Fourier decay and a certain geometric condition.</P>

A Study on Optimized Size of a Mobile Harbor for South Korea Coastal Service

Heo,Sung-Kuk,Park,Nam-Kyu 한국항해항만학회 2011 한국항해항만학회지 Vol.35 No.2

The aim of paper is to calculate the optimized size of Mobile Harbor(MH) which would be operated in South Korea coast area. MH is the combined entity which has the function of both ship and container port. In estimating the optimized size, the total cost concept is applied to the different size of MH. Trade-off factors for calculating total cost are MH cost and the over-capacity lost cost. The factors for MH cost estimation are the cargo demand, distance from origin to destination, voyage route and MH's fixed and variable cost in both sailing and port. The other cost is the over-capacity lost cost which is occurred from dead space in case of oversize compared with a voyage demand. The alternatives for the least cost are 250TEU, 500TEU, 750TEU and 1,000TEU sized vessel. The result of research is that 250TEU sized vessel is optimized in a South Korea costal service. If the coastal area be separated in terms of voyage distance or the specific area in considering trade, the optimized size is changed depending upon distance.

Workplace Spirituality And Its Relationship To Leadership

Heo,Kap Soo 한국인적자원관리학회 2010 인적자원관리연구 Vol.17 No.1

직장 영성은 (WS : Work Spirituality) 완전성과 기쁨을 수반하는 작업장 활동을 통해 근로자가 체험하는 초월적 경험으로 정의된다. 영성적 리더쉽은 사명감과 소속감을 동기부여함으로서 근로자들의 영감을 고취시키는 리더의 능력을 뜻한다. 이 두 개념 간의 관계를 밝히기 위해, 본 연구에서는 두 선행 연구를 분석하기로 한다. 첫 번째, Reave의 연구는 영성적 가치와 리더십 효과 간의 관계에 대한 문헌적 증거를 제시한다. 그녀의 연구가 효과적인 리더의 특성을 밝히는데 집중하고 있기 때문에, 환경적 맥락을 구체화시키고 리더-추종자 간 적합성을 고려하는 것이 필요하다고 여겨진다. 두 번째, Duchon과 Plowman은 직장 영성과 수행성과 간의 관계를 고찰하고, 그에 따른 리더의 역할을 추론했다. 샘플의 수가 적고 편향되어 있다는 제한점에도 불구하고, 이 연구는 직장 영성에 대한 경험적 연구의 가능성을 제안해준다. 이선행연구들은 직장 영성에 대한 체계적 이론의 개발과 다양한 산업군에 대해 이론을 적용하는 후속 연구가 필요하다는 점을 시사한다. Workplace spirituality is defined as employees’ transcendental experiences through workplace activities which lead to completeness and joy. Based on this definition, spiritual leadership indicates a leader’s ability of inspiring and motivating other organization members through “calling” and “membership”. In order to identify relations of these concepts, two selected articles were critiqued. First, Reave’s research provided literary evidence of the relationship between spiritual values and leadership effectiveness. While her research focused on the characteristics of effective leader, subsequent research is needed to concretize environmental contexts and consider leader-follower fit. Second, Duchon & Plowman (2005) examined the relationship between work unit spirituality and work unit performance and made inferences about the role of leaders. Though the sample is so small and the composition of sample is somewhat biased, this research presented the potential of empirical study about workplace spirituality.

충청도 사혼제 속의 연행 인형 연구

허용호(Heo Yong-ho) 한국무속학회 2002 한국무속학 Vol.0 No.4

본 연구는 ‘연행 인형’이라는 개념을 사용하여 충청도 사혼제 속에 등장하는 허수아비에 주목한다. 생명이 없는 짚으로 만들어진 허수아비가 어떠한 과정을 거치며 무엇인가를 의미하는 생명이 있는 존재, 곧 연행 인형으로 전환되는 과정을 살핀다. 이러한 고찰의 과정은 곧 충청도 사혼제 속의 허수아비들의 연행 인형화 과정을 기술하는 것이다. 허수아비의 조형 과정과 외양에서 연행 방식 그리고 의미화에 이르는 과정을 기술하는 것이다. 덧붙여 이러한 연행 인형화 과정에서 나타나는 여러 특징들의 나타나는 이유에 대해서도 함께 추론해 보았다. 논의의 결과, 충청도 사혼제 속 허수아비들은 그 조형 과정과 외양에서 짚과 헝겊 등 내구성이 약한 재료로 금기와 제약을 거친 제작자가 짧고 단순한 제작 공정을 거쳐 평면적이고 소박한 연행 인형을 일회적으로 제작한다는 특징을 드러낸다. 연행방식의 경우, 그 발화 연행에서 ‘보이는 연행자 발화의 대상’으로 나타나고 있으며, 움직임 연행에서는 ‘보이는 연행자의 공공연한 조종’이라는 특징을 보인다. 이러한 연행 방식은 ‘드러내는 연행 방식’이라는 공통점을 가진다. 의미화 과정의 경우 ‘축성이라는 의례를 거쳐서 초자연적인 존재인 미혼인 채로 죽은 영혼으로 영속적 변환’이라는 양상을 보인다. 충청도 사혼제 속 허수아비들의 연행 인형화 과정에서 나타나는 이러한 특징들은 종교ㆍ주술적 문화 전통이라는 문화적 기반에서 기인하는 것이다. 즉, 충청도 사혼제의 연행 공동체는 질병이나 재앙의 퇴치 또는 정신적 안정을 보장받기 위해 초월적 존재를 대상으로 제의를 준비한다. 이를 위해 그 대상이 될 연행 인형을 제작한다. 굿이라는 제의 문맥 속에서 초자연적인 존재 인 미혼인 채로 죽은 영혼을 의미하는 연행 인형을 제작한다. 초자연적 존재를 인형과 동일시하고 있다는 점에서 주술적이다. 주술적 의미 작용이 이루어지고 있는 것이다. 여기서 강조되며 중요시되는것은 재미나 흥미 또는 신기함보다는 주술적 효용이나 효과이다. 따라서 연행 인형의 외양이나 연행 방식에 강조점이 두어지지 않는다. 그 결과 나온 특징적 양상이 단순하고 소박한 외양과 드러내는 연행 방식이다. 충청도 사혼제 속 연행 인형의 외양적 특징은 공유된 종교 주술적 믿음 체계 속에서 관념적 존재를 환기시키는 데에 그 강조점이 두어진 주술적 조형임을 드러낸다. 드러내는 연행 방식 역시 종교 주술적 믿음이 중요하고 의례적 행위가 요구되는 주술적 연행 방식임을 드러낸다. 의미화 양상 역시 연행 인형과 초자연적 존재를 동일시하여 연행 인형을 영속적으로 전환시키는 주술적 의미 작용의 양상을 드러내고 있다. 본 연구에서 이루어진 논의는 그 동안 인형극에만 한정된 우리의 인형 연행 연구의 편향성을 교정하는 계기가 된다. 오락ㆍ예술적인 인형극과는 다른 양상을 보이는 주술ㆍ종교적 인형 연행의 양상을 살피게 되어 우리의 인형 연행의 또 다른 측면을 구체적으로 확인하게 된 것이다. 나아가 이 연구는 인형극이라는 한정된 연구에서 인형 연행이라는 보다 개방적이고 너른 연구 영역으로 나아가는 시발점이 될 것이라 믿는다. This study intends to examine the Heo-su-a-bi(scarecrow: 허수아비) in Chungcheong-do SaHonJe(Soul marrage ritual: 사혼제). For this, I will use the concept, 'puppet performing object' which means the material images of humans, animals, or spirits that are created, displayed, or manipulated in narrative or dramatic performance. In chapter Ⅱ, I examine the process of moulding puppet performing object and aspects of their appearances. The process of moulding puppet performing object are simple manufacturing process by shamans who are confined by taboo. The appearances of puppet performing object are figure of the whole body in full dress with a humble and flat face. In conclusion, the process of moulding puppet performing object and aspects of their appearances are the process of completing non-individual appearance with natural markers(biological, and material traits) through the simple manufacturing process by the producer who is restrained with taboo. To make puppet performing object animated, the performance by a human performer is needed. Chapter Ⅲ deals with the acts of a human performer. The performance of a human performer is mainly presented in a way of utterance performance and movement performance. Utterance performance is 'object of a visible performer's utterance'. In this utterance performance, there is no utterance of puppet, which only exists as the object of performer's utterance. Movement performance is 'overt operation by a visible performer'. These performance methods of puppet performing object are common to revealing in performance process. In chapter Ⅳ, I look into the signification of puppet performing object as the whole including the appearance, utterance, and movement. The signification of puppet performing object is the puppet performing object which shows 'transformation(perpetual transformation)' as supernatural existence(the sprit of youth put to death as an unmarried). After passing through some ritual process, the puppet performing object begin to speak and move and are regarded as a living thing by a performer, and then they are transferred into supernatural existence. In chapterⅤ, I examine the puppet performing object and cultural grounds. The puppet performing object of SaHonJe features result from the cultural grounds. The cultural grounds according to each features are summarized as follows. The features in the manufacturing process of puppet performing object are the product of cultural grounds as 'incantatory or religious orientation' which evokes an ideational existence in belief system. In performance process of , the revealing performance is related with the incantatory performance demanding the ritual ceremony and religious belief. In signification of puppet performing object is described as the incantatory signification of ritual performance producing the perpetual transformation into supernatural existence.

A Newly proposed control methodology applied to the aeroelastic system experiencing flutter is investigated and its performance is verified experimentally. The flexible cantilever beam slicked with piezofilm sensor and piezoceramic actuator is modelled in physical domain. Dynamic moment equation for the system is derived via Ito's stochastic differential equation and F-P-K equation. Also system's characteristics in stochastic domain is analyzed simultaneously. LQG controller is designed and used in physical and stochastic domain. It is shown experimentally that the vibration of beam is controlled effectively by designed LQG controller in physical domain. By comparing the result with that of LQG controller designed in stochastic domain, it is shown that the new control method, called Heo-stochastic control technique, has better performance as a controller.

Objectives: The purpose of this study was to assess the correlation relationship between personal exposure and urinary hippuric acid in biological monitoring for airborne toluene in an industrial complex and in general environments. Methods: Personal exposure to toluene and its metabolite, hippuric acid, in urine were simultaneously measured in occupational environments area near an industrial complex and in general environments. The study subjects were divided into three types: 137 workers who use organic solvents in the workplace, 210 residents living near a dyeing industrial complex, and 379 residents living in general environments. The toluene exposures of workers and residents were measured by a passive sampler for four days. The urine of participants was sampled when the passive samplers of personal exposure were collected. Results: The toluene and hippuric acid concentrations of workers were the highest, followed by the concentrations of residents living near a dyeing industrial complex and residents living in general environments. The coefficient of correlation between the concentrations of toluene and hippuric acid among workers was 0.749 (p<0.01) in the workplace. On the contrary, correlations between the concentrations of toluene and hippuric acid among residents living near a dyeing industrial complex and residents living in general environments were all not significant. The relationship between the concentrations of hippuric acid and toluene in three types could be described by the exponential growth model. Conclusions: This study analyzed the relationships between toluene exposure and the concentrations of hippuric acid in urine in high, middle, and low exposure environments, and could be described by the exponential growth model.

Aims: Chronic Hepatitis C Virus (HCV) infection increases the risk for progressive liver disease, hepatocellular carcinoma and negatively impacts the patient’s quality of life. HCV treatment is evolving with direct acting antivirals but IFN based therapy has been the standard of care for many years and remains available in some countries. The MOSAIC study aims to characterize patients with chronic HCV infection and assess the impact of IFN-containing treatment on health-related quality of life, work related productivity and health care utilization. Methods: MOSAIC is an international prospective multicenter observational study that has been conducted in 20 countries. Consecutive patients with chronic HCV infection were enrolled and those who initiated an IFN based regimen were prospectively followed for 48 weeks. We report results from the Korean cohort Results: 100 patients were enrolled: 86 were treatment naïve and 14 were treatment experienced. 33 patients initiated an IFN based regimen: 6 patients started IFN + RBV, 26 patients started Peg-IFN + RBV, none started Peg-IFN + RBV + DAA and 1 patient received other treatment. Among the treated cohort, demographic and disease characteristics were the following: the mean age was 54.5 years; 14 patients were male. 14 had minimal or no fibrosis, 2 portal fibrosis, 3 bridging fibrosis and 6 patients suffered from cirrhosis. HCV Genotype distribution was as follows: genotype 1: 11; genotype 2: 19 and genotype 3: 3. Table 1 describes the results at baseline and changes over 4, 12 and 48 weeks and end-of-treatment (EOT) for the quality of life and work productivity outcome measures (EQ-5D-5L, HCV-PRO and WPAI). Conclusions: Results from the Korean cohort of the MOSAIC study show a moderate trend for deterioration of health-related quality of life and work productivity associated with IFN based treatment for patients with chronic HCV infection during treatment period.

A Case of Erythema Multiforme A ssociated with Malignant Lymphoma Un Cheol Yeo, M.D., Kwang Hyun Cho, M.D., Yoo Shin Lee, M.D., Dae Seog Heo*, M.D., Seoung Chul Lee**, M.D Department of Dermatology and Internal Medicine*, College of Medicine, Seoul National University, Seoul, Korea, Department of Dermatology**, College of Medicine, Inha University, Kyung Gi Do, Korea We report a case of erythema multiforme associated with malignant lymphoma. Fifty-six-year-old male patient visited our clinic complaining generalized skin lesions which were compatible with erythema multiforme clinically and histopathologically. The skin lesions were treatment-resistant, recurrent and persistent for 3 years. In consideration of old age, atypical features of erythema multiforme and no other demonstrable etiology of erythema multiforme, we studied for internal malignancy. Malignant lymphoma at the duodenum was revealed by UGI series, abdominal CT, and endoscopic biopsy. After chemotherapy, the tumor mass and active skin lesions were cleared simultaneously. Erythema multiforme may be regarded as one of the paraneoplastic syndromes.

고등학생과 대학생의 기체의 성질에 관한 오개념 비교

윤회정,우애자 이화여자대학교 교과교육연구소 2007 교과교육학연구 Vol.11 No.2

본 연구의 목적은 고등학생과 대학생의 기체의 확산과 온도변화에 따른 부피변화에 대한 개념을 살펴보고, 학생들이 가지고 있는 오개념의 종류와 학년 간에 나타나는 오개념의 차이점을 조사하는 것이다. 본 연구를 통해 얻은 결론은 다음과 같다. 전반적으로 대학생은 고등학생에 비하여 기체의 성질을 올바르게 이해하고 있는 것으로 나타났고, 대학생의 경우 학년에 따른 이해도 차이는 거의 없는 것으로 보인다. 대학생은 고등학생보다 적은 종류의 오개념을 가지고 있는데 이는 학습을 통하여 일부 오개념이 수정되기 때문으로 판단된다. 기체에 관한 입자적 수준에서의 이해에 대한 부족으로 생긴 오개념은 학습에 의해 일부 올바른 개념으로 전환되기도 하지만 고등학생과 대학생에게 공통적으로 나타나는 것으로 보아 쉽게 수정되는 것은 아님을 알 수 있다. 또한 학생들은 수업에서 많이 사용되는 익숙한 내용의 문항에는 공식이나 암기한 지식들을 그대로 이용하여 설명하는 경향이 있고, 이런 경향은 고등학생들보다 대학생들에게 더 많이 나타난다.

The aim of this paper is to search an efficient academic translation skill for improvement of university students' reading ability. For this aim, I had referred to the views of specialists in practical business field. First of all, to select of the suitable meaning of a word in a sentence is very important and basic factor as we translate. Therefore, using dictionary might be very helpful to translator. Secondly, precise reading of a text is very effective to avoid mistranslation of text. The third, a literal translation is more efficient than the free. In addition, most specialists seem to concede that the literal translation is very recommendable method too, because it has many merits which can fulfil to various readers who are having different purposes. Lastly, I want to add that the most important thing in translation is the ability of Korean. For it will be the intermediator of a culture content, besides we would be appreciate the original writings with our mother tongue.
